[0002] Tlhe present invention also rel=ates to a blower type ch. emical diffusing apparatus as a blower type vermin or insect pest econtrol apparatuss for applying airflow to a c¢ hemical receptacle retai ning a vermin or insect control component to emanate or diffuse such «control componen t together with air into an atmmosphere.
[0003] The present invention also rel ates to a blower type clmemical diffusing apparatus as a blower type chemical emanating apparatus provided with a chemical receptacle charged with a volatile clmemaical serving ass an insecticide, repellent, areomatic, deodorant, germi cide or fungicide and an air blower whereby afir is drawn through an air inlet port and air is emanated or diffused through an outlet port mnto an atmosphe re together with such volatile chemical volatilizing fr-om the chemical receptacle and occluded into air.
[0004] The present invention also relates to a chemical cartri dge for retaining a volatile chemical such ass an insect pest control agent, aromatic, deodorant or germicide and permitting such volatile chemi- cal to be emanated or diffused into arm atmosphere from the ckemical cartridge when used in a blower type ¢ hemical diffusing appara_tus.
[0005] The present invention also rel ates to a chemical impregnated body or rmember for retaining a volattile chemical such as am insect pest cont rol agent, aromatic, deodorant or germicide and per mitting such vola_tile chemical to be emanated or diffused into an atmosphere from the chemical cartridge when useed in a blower type chemi cal dif- fusing ap paratus.
Background Art
[0006] There is known a bloswer type chemical diffusing apparatus ams disclosed in JP 2002-291392 A.
[0007] Such a blower type chemical diffusing apparatus is provide=d in its body with an air blower, a chemical receptacle (chemical ca" tridge) and a power supply c ontainer wherein the air blower includes a fan and a motor, the chemical receptacle is stored with a volatile chemical and the power supp ly container contains a battery.
[0008] And, the motor is dri ven to rotate the fan, which causes air to flow through the chemical receptacle, which in turn volatilizes vol=- tile chemical and diffuses it nto an atmosphere.
[0009] With the volatile chemical and the battery becoming ineffe c- tive and ending their lives writh its use, the conventional blower type chemical diffusing apparatuss of the type described above 1s designed to make them replaceable for its continued use.
[0010] Thus, for example, the power supply container is designed to contain the battery replacea bly and have the chemical receptacle r-e- placeably mounted therewith and to be itself mounted replaceably in the apparatus body so that removing the power supply container froem the apparatus body allows replacing the chemical receptacle and tlhe battery.
[0011] This arrangement e mtails detachably interconnecting a pl u- rality of members together te enable replacing the chemical receptacle and battery and thus makes the structure complicated and costly.
[0012] Also, the need to rermove the power supply container from t he apparatus body and then to take the chemical receptacle and batte-ry out of the removed power s upply container for replacement requir-es troublesome handling and gzives rise to a chance that either the appa- ratus body or the power supply container may be lost while they amre detached one from the other .
[0018] Further, the inability to connect the motor for the air blower mounted in the apparatus body to the battery received in the powzer supply container by any cord calls for a complicated structure for electrically connecting them together. ——
[00147 Further, a volume of chem=dcal receptacle in the st=te where it fills a_ large number of particulate chemical impregnated bodies in a porou s receptacle body must be lar ge in thickness.
[00157] This requires that the apparatus body be large in t hickness.
[0016] There is also known a blower type apparatus for controlling harmful insects as disclosed in JP 2001-197856 A.
[0017] Such an insect control app aratus includes a chemical recepta- cle re taining an insect control cormponent or ingredient, a fan and a motor- which are all contained in aan apparatus body (in the form of a chamber) which in turn has an air inlet and an air outlet port wherein the rotation of the fan by means of the motor causes air to be drawn throu gh the air inlet port, to strikze the chemical receptac le and to 1s- sue tlhrough the air outlet port toggether with insect control ingredient into aan atmosphere, thereby eman_ating or diffusing the irsect control ingreadient into the atmosphere. [0018 1 A conventional insect control apparatus of this t=pe to make its in sect control function effective when il 1s carried on. a user and used in the outdoors, has its body formed with a pair of air outlet ports facing upwards and downwa rds, respectively, so tha t when used carrieed on the user it causes air containing insect control ingredient to 1ss ue both upwards and downw ards through the upwar d and down- ward facing air outlet ports, respe ctively. [0019 ] A conventional insect control apparatus of this type having its appar-atus body formed with upward and downward facirg air outlet ports so that when used as carriecl on a waist of the user it can cause air containing insect control ingr edient to issue selectively both up- wardss and downwards is designe d to have insect contrael ingredient reach. both the user's head and feset. With such a conven-tional insect contr ol apparatus formed simply with such upward an d downward facingz outlet ports alone, however, it takes time the insect control in- gredi ent reaches the user’s head a_nd feet and it is thus not possible to contr ol harmful insect from the v-ery beginning of use of the appara- tus.
[002] In an open space such as -the outdoors where the apparatus is used, air currents produced by w-ind flow and movements of the user —_— 3—
tend to fluctuate air flows disclhharged and prevent them from diffuks: ing into target directions and may not protect the user from sufferimg from insect attack.
[0021] Also, in a blower type chemical diffusing apparatus as dms- closed in JP 2004-24161 A whic h is designed to draw air through aan air intake or suction port by an air blower and to cause chemical vol a- tilizing from a chemical receptacle (chemical cartridge) to issue through an air discharge port together with air drawn, as shown in
Figs. 23 and 24 the apparatus body 241 is formed on its top with t he suction port 242 for drawing adr and on its two opposed sides wi.th such air discharge ports 243 for- emanating chemical entrained in air drawn. And, the suction port 242 on the top of the apparatus body 2 41 is provided with the chemical or chemical accommodating receptacle 244 in which the chemical is ret ained. This chemical receptacle 244 is formed in both its top and bottom with slits 245 opening in the fomrm of annual rings (or annual grow&h rings of a tree) through which air is allowed to flow. Further, the apparatus body 241 is provided in its In- side with the air blower 246 and has battery cells 247 received at t—wo opposite sides of the air blower 246, respectively, as a power supply for moving the latter.
[0022] With the apparatus 241 made up in this way, the air blowrer 246 built therein to work energrzed by the battery cells 247 draws air from the suction port 242 at its top through the chemical receptacle 244 and causes air drawn into and past the chemical receptacle 2244 while carrying chemical volatilizing there to emanate and diffuase through the air discharge ports 243 at its side faces into its environ- ment.
[0023] On the other hand, the apparatus body 241 has a wearing b elt 248 attached thereto to enable it to be worn on a user’s wrist or tthe like. Such a wearing belt 248 is flexible, thin and elongate and with a buckle 249 at one of its ends w ith which the apparatus body 241 can be worn on the user’s wrist or the like, thereby enabling the subj ect blower type chemical diffusing apparatus to be used fitted on &the wrist or the like.
[0024] A conventional blower type chemical diffusing apparatus of this type thus requires it’s appar atus body to include a chermical re- ceptacle containing a volatile ch emical, an air blower for «diffusing chemical volatilizing from the chemical receptacle into the environ- mnent and further a battery as a power supply for energizinsg the air blower as the weightiest component. As a result, the appara tus body tends to become large in size and heavy in weight, giving ri se to the «hance that this makes the user feel it hard to use the appar atus. Es- pecially in case the subject blower type chemical diffusing a pparatus 4s used as worn on the wrist or the like, the user may feel it dis- agreeable with the feeling of its size and weight.
[0025] There is also known a blower type chemical diffusing appara- tus as disclosed in JP 2002-29139 2 A.
[0026] In a blower type chemical diffusing apparatus of this type, its apparatus body includes an air blower, a chemical cartrid ge and a power supply container wherein the air blower has a fan and. a motor, the chemical cartridge comprising a porous receptacle that c.ontains a large number of particulate chem ical impregnated bodies impregnated with a chemical, and the powewx supply container accommmodates a battery.
[0027] And, it is so designed that rotating the fan with t-he motor causes air to pass through the re ceptacle and to emanate with chemi- cal entrained therein into the atmosphere.
[0028] A conventional chemical cartridge as mentioned aloove com- prises a porous receptacle that needs to contain a large n_ umber of particulate chemical impregnated bodies impregnated with a chemical must be large in thickness, requiring such a chemical cartrmdge to be large in thickness.
[0029] As a result, a blower type chemical diffusing apparatzus of this type requiring a chemical cartrid ge, an air blower and battemy cells to be all mounted within its app aratus body must become large in thickness as a whole.
[0030] Further, the convention al chemical cartridge as rmentioned above comprises a porous receptacle containing a large mumber of particulate chemical impregnated bodies impregnated with am chemical, and the chemical in these particulate chemical impregnat:ed bodies ugoon volatilization is entrained in air p assed through the receptacle amd emitted progressively into the atm osphere. When the chemical irmpregnated in the chemical impregnated bodies is depleted, the re: cexptacle as it carries the particulate cheemical impregnated bodies is tlkarown away as waste. [©031] Such chemical cartridges which thus require that they when u sed out be thrown away as waste, are unfavorable under social c1 cmumstances nowadays such as waste and energy-saving problems.
[032] There is also known a chemical i mpregnated body as disclosed im JP 2001-200239 A.
[033] This chemical impregnated bocly comprises a plurality of chemical carrying nets composed of twdsted yarn and laid one ov-er a nother wherein each of the nets is impr egnated with a chemical. [@034] A conventional chemical impreegnated body as mentioned a_bove in which a plurality of nets are laid one on another, can Tbe made, but may make the user feel it lmard to use this chemical irm- p- regnated body as having a plurality of nets laid one on another amd moreover may cause a user's hand to b e stained with chemical froem s uch a chemical impregnated body when held by the hand.
When the chemical impregnated in the nets is depleted, the mets are thrown away as waste like the chemical cartridge mention ed above. Such chemical impregnated body is unfavorable under social circumstances nowadays such as waste amand energy-saving problems. [ 0035] There is also known a chemical cartridge as disclosed in JP
IDesign Registration No. 1173150. [ 0036] This chemical cartridge comprisses a receptacle defined by an outer casing having an opening and an inner casing having an ope=n- i. ng wherein a large number of particulate chemical impregnated bod- ies impregnated with a chemical are re ceived in a space between t he outer and inner casings.
[0037] This chemical cartridge is dessigned to contain particulate —hemical impregnated bodies impregraated with a chemical in a
Limited portion of the volume of the c:artridge through which air is passed to entrain volatilizing chemical therein for diffusion into tthe s;atmosphere, is limited in the amount of chemical it can contain per wanit volume and if this is made largem must be larger in diamet er, —G—
volume and if this is made la rger must be larger in diam eter, thus making the cartridge body larger in size as a whole.
[0038] As a result, such a chemical cartridge requires a l=arge space for its accommodation in a blower type chemical diffusing apparatus and thus makes the apparatus body large in size. 10039] JP 2002-291392 previously mentioned also disclose s a chemi- cal impregnated body which uses a large number of carrie r particles impregnated with a chemical amd retained in a porous recep tacle.
[0040] As a result, this requixes that the receptacle be lazxge in size and hence in thickness as well, making here again the body of a blower type chemical diffusing apparatus as a whole large im size. [0041) In contrast, the chemical impregnated body if maade in the form of a sheet as a carrier impregnated with a chemical a nd thereby retaining the chemical can be sufficiently thin that it holdss the appa- ratus body thin enough.
[0042] However, a chemical irmpregnated body so made in wthe form of a sheet is so weak in rigidity that it cannot sustain itsel.[ its given shape. Thus, an attempt is made to sustain a given shape eof a chemi- cal impregnated body by supporting it in its central, outer peripheral and intermediate regions with its retainer receptacle.
[0043] These regions of the chemical impregnated body su:pported by the retainer receptacle are large in surface area and becorme entirely useless in serving to emanate and diffuse chemical impr-egnated in these regions because air cann ot pass through the regions.
[0044] In this connection there is also known a chemical irmpregnated body as disclosed in JP H11-9 2303 A which is in the form of a honey" comb impregnated with a chemical that is stronger in r-igidity and larger in the amount contain ing chemical per unit volumae than the sheet-like chemical impregnat ed body.
[0045] However, whichever of sheet-like or honeycomb type, such a conventional chemical impreg nated body once it is used o ut or spent in a blower type chemical diffusing apparatus in diffusirag chemical into an atmosphere must be thhrown away as waste.
[0046] Such a conventional chemical impregnated body of throwaway type is unfavorable under social circumstances nowaday~s at waste —
and resource-saving standpoints.
[0047] For this reason, it is conceivable to ma ke spent chemical im" pregn ated body reusable by impregnating it a gain with chemical to have mt retain the chemical again.
[0048] Then, while it may be possible to m ake reusable a spent chem cal impregnated body especially if of she et type by dripping to impre=gnate it with chemical and have it retai n chemical again, im- pregn_ ating a honeycomb type impregnated bodZy, shaped to include a large number of cores, with chemical requires dipping the honeycomb body in a container filled with a large quanti ty of chemical or con- tinuirag to supply it with a large quantity of chemical and for a time period enough to achieve required impregnation. Not only does this requi re such a large quantity of chemical but also there will a spe- cializ ed facility become mandatory in dealing wath the chemical.
[00498] Thus, while a large number of chemic al impregnated bodies can b-e re-impregnated with chemical and thereeby made reusable suc- cessiwely as in a factory or manufacturing plarmt without difficulty to meet these requirements, it is altogether impra ctical for an individual user to attempt to make a conventional spent chemical retainer or cartridge reusable because a surplus chemical is wasted and cannot be de alt with.
Discl osure of the Invention
[0050] It is an object of the present inventiosn to provide a blower type chemical diffusing apparatus that is simp Je in structure and low in co st to enable a chemical cartridge and a Battery to be renewed, that is easy to operate in renewing a chemical cartridge and a battery, that facilitates electrical connection of the battcery to the motor in the bloweer and yet that is thinned as a whole.
[00571] It is another object of the present 1 nvention to provide a blower type chemical diffusing apparatus that configures the air dis- charage port so as to discharge air forcibly in desired directions and, whera the apparatus is used worn on the use r’s waist, to cause the harmful insect control component to reach the head and feet quickly, thereby making it effective to control harmful insects from the begin-
ning of use of the apparatus.
[0052] It is still another object of the present invention to provi de a blower type chemical diffusing apparatus that is smaller in size and light in weight and can be used comfor tably by the user without feel- ing it disagreeable.
[0053] It is a further object of the p-resent invention to provi de a chemical cartridge that is thinned, that can sustain its given slaape, that is easy to handle and free from contaminating a use’s hand. and whic h when used out can be refilled with chemical and can be re-used over and again. [005 4] It is still a further object of thes present invention to prov ide a chemical cartridge that is large in ammount of chemical per unit vol- ume and that can be smaller in overall size. [005 5] It is yet a further object of the present invention to prov ide a chemical impregnated body that can hold its given shape, thas can emit the chemical it retains into an at mosphere efficiently and vwhich whem depleted of chemical can be refill ed with chemical by a user eas" ily. [005 6] There is provided in accordanc e with the present inventi on in a first aspect thereof a blower type chemical diffusing apparatus hav- ing an apparatus casing body, an air b lower, a chemical cartridge and a battery, characterized in that the apparatus casing body comprises a fixst side and a second side counter part casing body openably= cou- pled together by a hinge, the first side casing body having a b lower mow nting recess, an airflow section zand a battery accepting recess, the second side casing body having an airflow section spaced fromm the airflow section in the first side casings body; the air blower has a fan adapted for rotation by a motor, the faan and the motor being mo-unted in t he blower mounting recess; the ch-emical cartridge is disposed be- tween the air blower in the first side casing body and the airflow sec- tiom in the second side casing body; th_e battery is removably accepted in the battery accommodating recess; the blower mounting and bat: terys accommodating recesses are spaeced apart from each other in a plamar direction and positioned not to overlap in a direction of” their thicknesses; and the chemical cartrid_ge contains a chemical inmmpreg-
nated bo«dy having a carrier in the form o fa sheet impregnated vwith a chemical .
[0057] Aa blower type chemical diffusing apparatus in this asp ect of the present invention, which permits the chemical cartridge amad the battery in the first side counterpart casing body to be taken owt and reloaded simply by turning open the sec ond side counter part casing body about the hinge from the first sides counterpart casing bo-dy, 1s simple amd reduced in cost structurally ir enabling these consumables to be remewed.
[0058] Since opening the second side co unter casing body simply al lows thes chemical cartridge and the battery to be replace, their re- placememt is easy. Moreover, with these two counterpart casingss then held cou pled together, there can either o f them be lost from the other by no means.
[0059] Moreover, since the motor and tlhe battery for the fan i= posi- tioned im the first side counter part casi ng body as a common c=asing, it is altogether easy to electrically conn ect them; the motor aiad the battery can easily be connected electrical ly.
[0060] WFurther, since the chemical cartridge is thin and the cheemical cartridge and the battery are positioned without overlapping ir a di- rection of their thicknesses, the entire apparatus is thinned.
[0061] Xn a blower type chemical difftasing apparatus as setz forth above, tThe apparatus casing body may bes formed with a hook emgage- ment se ction to which a hook of a hangmng aid can be engaged and a hole in which a fitting section of hanging: aid can be fitted.
[0062] "This feature allows the apparatuas to be used while it is hung or left to stand on a table or the like.
[0063] "The present invention also provicles in a second aspect thereof a blowe r type insect pest control appar atus including: an app aratus casing body having an air inlet port and a first and a second amir dis- charge poort, and a chemical receptacle, a fan and a motor in tthe ap- paratus casing body, the chemical receptacle retaining a chemiacal im- pregnat ed body impregnated with an irisect pest control component, whereby rotating the fan by the motor a llows air to be drawn through the air dnlet port and air drawn to strikes on the chemical impre gnated body in the chemical receptacle and air entraiming insect pest control componemt therein from the chemical impregmated body to emanate and difftase into an environmental atmosphere , characterized in that: the first and second air discharge ports are ea~ch in the form of a hole having a. radial length and inclined to a circummferential direction in which th:e fan rotates whereby when the appaaratus is used with the apparatuas casing body worn on a user, air is discharged upwards through the first air discharge port and down wards through the sec: ond air discharge port.
[0064] Mm blower type insect pest control apparatus in this aspect of the pres ent invention, which permits air corataining an insect pest control component to be forcibly discharged through the first and second a ir discharge ports, is advantageously applicable to where the apparatias is used with its casing body worn on the user’s waist 1n that air containing an insect pest control com ponent is allowed to is- sue forcibly through the first and second air d ischarge ports and thus allowed to reach the user’s head and feet quickly
[0065] This provides an apparatus that acts e=fficiently from the very beginnimg of its use.
[0066] Ln a blower type insect pest control apparatus as set forth above, the first and second air discharge pomts may each be in the form of = hole that communicates its inner inl et opposed to the fan to its outer- outlet open in an outer face of the apparatus casing body and wherein the hole has an upstream side guide face connecting an up- stream sside inlet hole edge of the inner inle® and an upstream side outlet hele edge of the outer outlet continuously to each other and a downstream side guide face connecting dowrastream side inlet hole edge of #the inner inlet and a downstream side outlet hole edge of the outer owatlet continuously each other, the up stream side and down- stream side guide faces being each inclined to a circumferential direc: tion in which the fan rotates.
[0067] With the upstream side and downstresam side guide faces each inclined towards a circumferential direction i n which the fan rotates according to this feature, air containing the =nsect pest control com- ponent can be flushed not only forcibly but also smoothly.
[0 068] In a blower type insect pest control apparafbus as set forth above, the apparatus casing body may be configureed to comprise a bzise member having the first and second air discharges ports and a fan acccommodating chamber, a cover member having th e air inlet port ard removably attached to the base member at one -of its sides in a di rection of its thickness and a chemical accommo dating chamber di sposed between the base and cover members and opeen to the fan ac: coommodating chamber. T hen, the base member may bee formed with a m otor accommodating chaamber and a battery accommodating chamber which are open in a rear face of the base member at its opposite side to- the cover member; and the motor and battery accommodating chambers may be adapted to accommodate the motor and the battery, re= spectively, and positioned so that the motor and th e battery do not oirerlap in a direction of thickness of the base member .
[0069] This feature perrmits the cover member to be removed to en- alble the chemical receptacle to be removed. Also, since the motor and tlhe battery are arranged not to over lap in a direction of the thickness of the base member, the entire apparatus can be thinn_ed.
[0070] In a blower type insect pest control apparawus as set forth aloove, the apparatus cas ing body may further be formed with a third air discharge port for discharging air entraining inssect pest control component therein, the third air discharge port being in the form of a hole having a radial lemgth and being inclined to a circumferential di rection in which the fan rotates whereby when the apparatus is ussed with the apparatus casing body worn on a user, zair is discharged obliquely upwards or obliquely downwards through tThe third air dis- charge port. (071) According to this feature, since air containing the insect pest control component is allowed to issue through the thi rd air discharge port obliquely upwards or obliquely downwards, it is possible to send tlhe insect pest control component more to either the head or the feet tlaan to elsewhere.
[072] In a blower type insect pest control appara-tus as set forth above, the third air discharge port may be in the for:am of a hole that communicates its inner inlet opposed to the fan to its outer outlet —i2-—
open in an. outer face of the apparatus casing body and wherein the hole has ain upstream side guide face conrecting an upstream side inlet hole edge of the inner inlet and an wapstream side outlet hole edge of thee outer outlet continuously to eack other and a downstream side guide face connecting a downstream sade inlet hole edge of the inner inlet and a downstream side outlet ho le edge of the outer outlet continuouszly each other, the upstream si de and downstream side guide facess being each inclined to a circumfearential direction in which the fan rot ates.
[0073] Acczording to this feature, air containing the insect pest con- trol compoment can be discharge not only for cibly but also smoothly.
[0074] In a blower type insect pest control apparatus as set forth above, the apparatus casing body is formed with a subsidiary air dis- charge por-t adapted to discharge air laterally when the apparatus is used with the apparatus casing member womn on a user, thereby ena- bling the apparatus to emit air in all directions with upwards and downwardss inclusive.
[0075] According to this feature, when the sapparatus is used as worn on the use 1, the insect pest control component can be diffused evenly around thes user.
[0076] In a blower type insect pest control apparatus as set forth above, the subsidiary air discharge port m ay be larger in air resis: tance than. the first and second air discharges ports or the first, second and third sir discharge ports.
[0077] Th is feature is advantageously app_licable where the appara- tus is usecd as worn on the user’s waist in tzhat air containing the in- sect pest control component can be emitt ed less forcibly but ade- quately laterally of the user and at the samme time forcibly enough to its head ard feet.
[0078] In a blower type insect pest contreol apparatus as set forth above, the subsidiary air discharge port ma y be in the form of a hole that comme unicates its inner inlet opposed tco the fan to its outer out- let open ini an outer face of the apparatus ca sing body and wherein the hole has =an upstream side guide face conmmecting an upstream side inlet hole edge of the inner inlet and an wupstream side outlet hole edge of the outer o utlet continuously to each o ther and a downstream side guide face coranecting a downstream side inlet hole edge of the inner inlet and a downstream side outlet hole sedge of the outer outlet continuously each other, the upstream side and downstream side guide faces being e-ach inclined to a circumfere ntial direction in which the fan rotates. Then, the subsidiary air discharge port ma be less open in the direction of rotation of the fan th-an the first and second air discharge ports. or the first, second and third air discharge ports.
[0079] According to this feature, air can be discharged forcibly through the first and second or the first, seccond and third air dis- charge ports withosut fail while air is discharged less forcibly through the subsidiary air discharge port without fail.
[0080] The presemt invention also provides in. another aspect thereof a blower type chermical diffusing apparatus having an air blower and a chemical recepta_cle stored with a volatile chemical, characterized in that it comprises: an apparatus casing body vaherein air is drawn by the fan through am air inlet port and dischar ged through an air dis- charge port while entraining chemical from #the chemical receptacle therein; a power casing body separated fromm the apparatus casing body for containingz a power supply for the air "blower in the apparatus casing body: and a connection cord for connec ting the apparatus cas- ing body and the power casing body to each osther and for electrically energizing the air blower in the apparatus casang body from the power supply in the power casing body.
[0081] A blower type chemical diffusing apparatus in this aspect of the present invention is designed to separate the power supply (bat- tery) section as thme weightiest component frorm the other components and to include them separately in a power ca sing body and an appa- ratus casing body and thereby to reduce the a pparatus casing body in both size and weight as can conveniently be wrorn on the user's wrist.
Then, the power casing body can be worn sepa rately, e. g., in a pocket in a pant, trouser or suit, thereby permitting the apparatus to be used comfortably while relieving the user from feeling of disagreeableness it has had when w=earing the conventional app aratus large in size and heavy in weight. [Ln addition, a connection cor d as set forth is conven-
lemtly provided.
[08082] In a blower type chemical diffusing apparatus as set fo rth abe ove, a connection cord as set forth mmay advantageously be such t’hat it can be removably attached to the apparatus casing body and/or the poewer casing body. [0 083] This feature allows the connection cord first connected to o nly either or neither of the apparatus amd power casing bodies to be at- ta ched to the other or both only afte they are fitted on, thereby fa- cillitating their individual fitting operaations markedly. [0 084] In a blower type chemical d iffusing apparatus as set forth al>ove, it may have a fitting means fo r fitting the apparatus casing to ar object to be fitted. [0 085] In a blower type chemical d.iffusing apparatus as set forth above, it may have a fitting means for fitting the power casing toe an olo>ject to be fitted. [De 086] In a blower type chemical d_iffusing apparatus as set forth aloove, it may have a fitting means for fitting the connection cord to ar object to be fitted.
[0087] These features allow the blower type chemical diffusing appa: r=atus to be readily set up by suitaloly fitting the apparatus casing body, the power casing body and the connection cord individually.
[088] The present invention also pr-ovides in another aspect the reof a chemical cartridge, characterized Gn that it comprises: a chem ical irmpregnated body in the form of an air permeable and liquid absorp: ti. ve sheet impregnated with a chemi cal; a retainer receptacle for re- taining the chemical impregnated body, the retainer receptacle hawing a hold section for holding an upper zand a lower face of the chemmical irmpregnated body across them and an air passage section through w~ hich air flows; and a space formed between hold section and chemi: caal impregnated body and opening t.o an outside through an air flow seection formed in the hold section. [D089] According to this aspect of tThe present invention, a chemical csartridge is provided that is thinned by utilizing a chemical imp-reg- n.ated body that is thin in the form of a sheet held by a retainer" re- ceeptacle which also serves to sustai n its given shape and to protect the hand fr om contamination by chemical.
[0090] Also, a volume of chemical retai. ned in those areas of a chemi- cal impregmated body where it is held Woy the retainer receptacle and where ther e is no direct flow of air is admitted into the space s tated where it is entrained in air flowing the=re and then discharge int o the environmental atmosphere. Hence, subsstantially no volume of chemi- cal retained in the chemical impregnate d body will become useless.
[0091] In a chemical cartridge as set forth above, the hold section may have: a recess formed where thes hold section is contactdng a lower face of the chemical impregnated body: a space formed between the recess and a lower face of the chem_ical impregnated body; amd an airflow hole formed, where the hold ssection 1s contacting an -upper face of the chemical impregnated body, so that it is opposed to recess, thereby providing an air flow section.
[0092] According to this makeup of thee chemical cartridge, the recess can be use d to pool a liquid chemical gpoured into it through th e air- flow hole. The liquid chemical pooled in Lhe recess is allowed te per: meate into the chemical depleted bods, progressively and thereby to regenerate: into a chemical impregnated body.
[0093] Th e present invention provides in still another aspect thereof a chemical cartridge, characterized in that it comprises: a chemical impregnat-ed body in the form of an aizx permeable and liquid albsorp- tive sheet impregnated with a chemi cal; and a retainer receptacle having a receptacle base member ancd a cover member for holding chemical -mpregnated body wherein: the receptacle base member comprises a central support section, a peripheral support sectiomn and a plurality of intermediate support s ections connecting the c entral support sesction to the peripheral suppoort section to form an airflow passage sexction, the receptacle base rmember being formed with a re- cess in at least one of upper faces of the central, peripheral a nd in- termediatee sections and with a space Ibetween this recess and a lower face of thes liquid impregnated body, cover member comprises a central hold section, a peripheral hold section and a plurality of interm ediate hold secti ons connecting the central Inaold section and the peripheral hold section to each other to form a.n airflow passage section, the cover memnber being formed with an airflow ole in at least one of #he central, p-eripheral and intermediate hold sections so that it is oOp- posed to —the recess, whereby the receptacle: base member and co-ver member ¢ an detachably be fitted with and coupled to each other to al- low air to flow through the airflow passage section in the recepta_cle base mem ber and the airflow passage section. in the cover member.
[0094] Heere again, a chemical cartridge is provided that can be thin, that can keep a chemical impregnated bod-y in its given shape and that can protect the hand from contaminatiom by chemical.
[0095] Also, with its central, peripheral a nd intermediate secti=ons held with the central support and hold section, the peripheral suppsort and hold sections and the intermediate secti ons of the receptacle b ase and cover members, a thin chemical impreg nated body can be firrmed held and also is easy to handle and maintain .
[0096] Moreover, a volume of chemical retamined in at least one a rea of a chemical impregnated body where it is held by a support an d a hold sectdon and where there is no direct flaow of air is admitted 1 nto the reces s stated where it is entrained in a ir flowing there and t_hen discharge= into the environmental atmospher e. Hence, substantially= no volume o f chemical retained in the chemic al impregnated body will become u seless.
[0097] T he recess, here again, can be used to pool a liquid chem ical poured irmto it through the airflow hole. The liquid chemical pooled in the recess is allowed to permeate into thes chemical depleted b ody progressi vely and thereby to regenerate int o a chemical impregnamted body.
[0098] Ir a chemical cartridge as set forth above, the receptacle I»ase member may be formed with a recess in tle central support secstion and annular recess in the peripheral supporst section.
[0099] A_ccording to this feature, the annular recess in the peripheeral support ssection allows liquid chemical to peermeate into the chem_ical depleted body from its whole periphery uniformly over its entire area.
[0100] Im a chemical cartridge as set fortch above, the central, pe- ripheral and intermediate support sections are identical in shape and size to tlhe central, peripheral and intermed.iate hold sections, res—pec-
tively. so that the airflow passage sections are identical in shape and size to each other. [01010 This makeup allows air to flow smoothly over the airflow pas- sage sections of both the receptacle Bbase and cover members an d thus chemi cal in the chemical impregnaxed body to emanate and diffuse into tBhe environmental atmosphere smoothly and efficiently. [01020 The present invention also perovides in a further aspect t hereof a che-mical cartridge characterized in that it comprises a chemical impre gnated body in the form of an air permeable and liquid a bsorp- tive sheet impregnated with a chem ical and a retainer recepta cle for containing the chemical impregnated body wherein the retairer re- ceptacle is formed in a central area thereof with a liquid pool recess such that liquid chemical stored in t he liquid pool recess is allo-wed to permeate towards a peripheral area «of the sheet.
[01037] Such a chemical cartridge is, here again, advantageous &n that it after use can be refilled. To this end, liquid chemical is supplied into the recess in the central area o f the retainer receptacle, amd liq: uid chemical pooled in this recess of the retainer receptacle is a llowed to permeate towards its periphery and then into the sheet bodly uni- formlw over its entire area.
[0104] A chemical cartridge can thu s be reused over and again.
[0105] Also, by being positioned at a_ center of the retainer receptacle, the li quid pool recess in no way immpedes the airflow from t_he fan which. can thus be used without was te and exploited efficiently to dif- fuse t he chemical into the environmental atmosphere. . [01067] Further, with the chemical impregnated body thin in th e form of a sheet retained by a retainer r eceptacle, the chemical camtridge can be thinned.
[01077] Moreover, a chemical recept-acle as defined above is ad-equate in keesping a chemical receptacle in_ its given shape and is also free from contaminating the hand with ckemical.
[01087] In a chemical cartridge as set forth above, the retainer recep- tacle may be formed in a peripheral area with a liquid pool recess such shat liquid chemical stored in the liquid pool recess is allo wed to permeate towards a central area of the sheet. the retainer receptacle is formed in a peripheral area with a lig uid pool recess sucka that lig uid che mical stored in the liquid pool r ecess is allowed to permeate towards a central area of the sheet.
[0109] This makeup allows liquid chemical supplied into stored in the liguaid pool recess in a central area o fa body to permeate towards its peripheral are and liquid chemical stapplied into and sto red in the periphe ral area to permeate towards th_e central area. Thus, even a large body can be impregnated with chemical relatively quickly.
[0110] In a chemical cartridge as set forth above, the retai ner recep- tacle for containing the chemical impre gnated body may c-omprise a recepta cle base member and a cover member; the receptacle base membewx comprises a central support s ection, a peripheral support section and a plurality of connecting se ctions connecting t he central and percipheral support sections to each other to form an airflow pas- sage se ction; the cover member comprise s a central hold sec tion, a pe- riphera_] hold section and a plurality of ¢c onnecting sections connecting the cen tral and peripheral hold sections to each other to form an air- flow pemssage section; a central liquid p ool recess formed of a recess formed in the central support section and a supply port formed in central hold section; and a peripheral 1 iquid pool recess formed of a peripheral recess formed in the periphe ral support section and a pe- riphera_l supply section formed in the peripheral hold sectior.
[0111] With its central and peripheral sections held betwe=en the re- ceptacl e€ base and cover members here, tlhe chemical impregmated body can be held firmly in a chemical cartridge, facilitating its handling and ma_intenance.
[0112] The present invention also provicles in a further aspeect thereof a chemmical cartridge characterized in that it comprises’ & chemical impreg nated body in the form of a sheet and a retainer receptacle contaimming the chemical impregnated boedy wherein’ the ch-emical im- pregna ted body comprises a carrier in “the form of an air permeable and ligguid absorptive sheet having a localized high liquidl retention region and impregnated with a chemical_
[0113] Here, with the chemical impreg-nated body being t hin in the form of a sheet and held by its retainesr receptacle, a chesmical car-
tradge that is easy to handle can b e provided. 6 [0 114] A chemical cartridge so co nstructed is, here too, advantageeous in that when its chemical is de pleted after use the career car be re -supplied with chemical in the Thigh .liquid retention region. Li quid chemical impregnated in the high liquid retention region of the career is then allowed to permeate pr-ogressively over into entire be ody, thmereby regenerating it into a faxresh chemical impregnated bod vy. A chemical cartridge can thus be used over and again.
[115] Moreover, the career cara accept a large quantity of li quid chemical at its high liquid retention region at a time. Liquid chemmical supplied into the high liquid region can then permeate into it pro- gwessively over its entire area. Thus, there 1s regenerated a body uni formly impregnated with and retaining chemical. [O116] In a chemical cartridge =is set forth above, a portion off the carrier may be made larger in thickness than its remaining portions to constitute the high liquid reteration region. [©1171] So made, the high liquid retention region higher in heigh=t can pxovide a sign that can be visuallly seen to if liquid chemical has been swpplied. [O118) The present invention provides in an another aspect ther eof a chemical cartridge characterized in that it comprises a chemica 1 im- p regnated body in the form of a pleated flat sheet material having a lzarge number of pleats impregnated with a chemical, the pleats are formed by alternating mountain fold and valley fold of the sheets ma- terial at certain widths, the sheet material itself being air permeeable a nd liquid absorptive, the pleate d sheet material having a peripheral a_rea jointed to prevent the pleats from getting out of shape. [€0119] With a chemical cartridgse so made its chemical impregmated be ody can retain an increased ameount of chemical per unit volumee and t he cartridge itself can thus be mmade smaller in size. [ 0120] In particular, a chemiacal cartridge that retains a large amount of chemical but is thin can thus be provided. [ 0121] A pleated sheet material whose periphery is processed tO pre- went the pleats from getting out. of shape allows air to flow subo sub- stantially uniformly over its ent ire area and thus chemical to d=ffuse substantially uniformly from the emxtire chemical impregna ted body. [O®122] A chemical cartridge as set forth above may furth er comprise a fixture for holding a peripheral area of the chemical i mpregnated b ody. [©1238] A chemical cartridge as set forth above may furth er comprise a receptacle containing the chemical impregnated body an d having an a irflow section. [©0124] Then, with the fixture or »eceptacle that can be held by the h.and a chemical cartridge can be provided that is easy to handle : while protecting the hand from con-tamination by chemical retained by t he chemical impregnated body. [€0125] The present invention also provides in another as pect thereof a_ chemical cartridge characterized in that it comprises: a chemical impregnated body in the form of a pleated flat sheet mater-ial having a large number of pleats impregnated with a chemical, thee pleats are formed by alternating mountain fo 1d and valley fold of thee sheet ma- t erial at certain widths, the sheet material itself being ai r permeable aend liquid absorptive; and a fixture for holding a periph eral area of t he pleated sheet material with that area squeezed to kee: p the pleats rot getting out of shape. [ 0126] With a chemical cartridge so made its chemical mmpregnated body can retain an increased amount of chemical per unit volume and t he cartridge itself can thus be made smaller in size. [ 0127] In particular, a chemical cartridge that retamns a large amount of chemical but is thin can thus be provided. [ 0128] Also, with its peripheral amea squeezed to keep thae pleats not getting out of shape, the pleated sheet material allows air to flow substantially uniformly over its ar ea and thus the chemical to diffuse substantially uniformly from the emtire chemical impregnated body.
[0129] Further, with the fixture that can be held by the hand, a chemical cartridge can be provided that is easy to handl_e while pro- ttecting the hand from contamination by chemical.
[0130] Moreover, with its peripheral area squeezed witlna the fixture to keep the pleats not getting out of shape, the pleated sh_eet material reed not be jointed separately and can be manufactured with greater ol easiness.
[0131] The present iravention also provides in a further aspect thereof a chemical cartridge characterized in that it comprises: a ch emical impregnated body in the form of a pleated flat sheet material heaving a large number of plea ts impregnated with a chemical, the pleats are formed by alternating mountain fold and valley fold of the she et ma- terial at certain widths, the sheet material itself being air permmeable and liquid absorptive; and a receptacle containing the chemical im- pregnated body and h aving an airflow section.
[0132] With a chemi cal cartridge so made its chemical impre gnated body can retain an increased amount of chemical per unit volurme and the cartridge itself can thus be made smaller in size.
[0133] In particular, a chemical cartridge that retains a. large amount of chemical b ut is thin can thus be provided.
[0134] Further, witha the receptacle that can be held by the Inand, a chemical cartridge can be provided that is easy to handle while pro- tecting the hand from contamination by chemical.
[0135] The present invention also provides in yet another aspect thereof a chemical cartridge characterized in that it comprises: a chemical impregnate d body in the form of a pleated flat shee® mate- rial having a large number of pleats impregnated with a chemical, the pleats are formed by alternating mountain fold and valley fold of the sheet material at cextain widths, the sheet material itself be ing air permeable and liquid absorptive, the pleated sheet material being deformable into a hollow cylindrical shape; and a rec-eptacle configured to includes an annular hollow and an axial hollow, t o allow air to flow through these hollows, and to accept the clemical impregnated body in the annular hollow.
[0136] With a chem ical cartridge so made its chemical retaimer can retain an increased amount of chemical per unit volume and tthe car- tridge itself can thus be made smaller in size.
[0137] In particular, a chemical cartridge that retains =x large amount of chemical but is thin can thus be provided.
[0138] Further, with the receptacle that can be held by the “hand, a chemical cartridge c an be provided that is easy to handle wh_ile pro-
te=cting the hand from conta mination by chemical. [®139] According to a che mical cartridge so constructed, a pleated skeet material which itself is liquid absorptive can, afte r use or de: pletion be, be refilled and thoroughly impregnated with liquid chemi cal; it can be reused over arad again. [D140] The present inven tion also provides in yet another aspect tkhereof a chemical impregnated body characterized in that it com- prises: a honeycomb body having a large number of honeycomb cores open to a pair of opposed s ide faces thereof in a direction of its thick: n ess and providing airflow passages parallel to the thickness direc tmon; and a sheet body disposed adjacent to one of side faces over an e ntire area thereof wherei n the honeycomb and sheet bodies are im- p regnated with a chemical.
[0141] A chemical impregmated body as mentioned above can sustain ints given shape wherein za honeycomb body acts also to reinforce a be ody.
[0142] A honeycomb body through which air flows smoothly does not i-mpede air flowing through a sheet body; the chemical re tained in the honeycomb and sheet bodies can be diffused efficiently ir to the envi- ronmental atmosphere. [ 0143] When the honeycoanb and sheet bodies are depleted of chemi- —=al, the sheet body can be supplied with chemical to allow the sup- plied chemical to permeate into the sheet body itself and also into the honeycomb progressively.
[0144] Thus, the user can readily regenerate a chemical impregnated body from a depleted body by simply a sheet body in the depleted body w~ith chemical to allow the supplied chemical to permeate into the sheet and honeycomb bodi es.
R0145] A chemical impregnated body as set forth above may further comprise a retainer receptacle for retaining therein honeycomb and sheet bodies and holding them in intimate contact with e ach other.
[0146] With a honeycoml> and a sheet body brought together into in- ~timate contact, .liquid chemical supplied to the sheet body is allowed -to permeate into the honeycomb body without fail.
[0147] In a chemical imp regnated body as set forth abo ve, the recep-
tacle comprises a receptacle base member having a support sectiosn for supporting the sheet body; and a hold member for fitting engage ment with the receptacle base member to hold the honeycomb and sheet bodies in intimate contact w=ith each other.
[0148] According to this m akeup, a honeycomb and a sheet body are brought into intimate contact without fail when the sheet bo dy 18 supported from a support s ection of a receptacle base member which is then fitted with and thereby coupled to a hold member.
[0149] In a chemical impregnated body as set forth above, the sup- port section is formed with a liquid chemical pool section and a chemical inlet port for supplying liquid chemical into the Liquid chemical pool section.
[0150] This makeup facilit ates supplying a honeycomb body wit h lig- uid chemical when liquid «<hemical is poured into a liquid che mical pool section through a supply inlet and the supplied liquid pooled is allowed to permeate into th e sheet body over its entire area.

Best Modes for Carrying Out the Inven®ion
[0152] At the outset, mention is made of a first form of imple=menta- tiom of the present invention.
[0153] Referring to Figs. 1 to 4, a blower type chemical diffussing ap- paratus according to the first form of immplementation of the in-vention includes an apparatus or casing main body 1, and an air blowver 2, a chemical cartridge 3 and a battery 4 which are contained in the casing main body 1.
[0154] The casing main body 1 compr-ises a first and a secon d coun- terpart casing member 10 and 11 open_ably interconnected by a hinge 12 =o they can make the casing main body 1 open and closed.
[0155] The first casing member 10 is extremely small in thaickness comapared with its planar size, namely thin plate-like. It is formed wit h a blower mounting recess 13, air passages 14 open to thes blower mournting recess 13, and a battery accommodating recess 15. Tae bloweer mounting recess 13 and the battery accepting recess 15 a-re each open to an inner side lateral face 10a of the first casing memb er amd are mutually spaced apart in a plane thereof so that they «do not lie one above the other in a direction of it s thickness. The air pa_s- sagess 14 open the blower mounting recess 13 to an outer surface 1@b of th e first casing member 10.
[0158] The second casing member 11 is extremely small in thickne ss compared with its planar size, namely thin plate-like. It can take twwo positions, viz. one in which it covers, and the other in which it uncov- : ers, both the blower mounting recess 13 and -the battery accommodat- ing wecess 15. The second casing member 11 1s formed with air pas- sage s 16 in an area thereof that is opposed to the blower mounti ng recesss 13 of the first casing member 10. [015 7] The air blower 2 includes a fan 20 an d a motor 21 mounted as recedved within the blower mounting recess 1 3 and is designed so tlmat the votation of the fan 20 by the motor 21 when the second casi ng member 11 is in its closed state causes air —to flow over the air paas- sage-s 14 of the first casing member 10 and the air passages 16 of t-he seco nd casing member 11. [015-8] For example, air may be drawn throu gh the air passages 16 of the second casing member 11 and discharged through the air passages 14 o fthe first casing member 10 into the atm osphere, or vice versa.
[019] The chemical cartridge 3 includes a chemical impregnat-ed bods’ that is a carrier in the form of a sheet impregnated witlm a chermical placed on an annular edge in the blower mounting recess 13 and. when the second casing member 11 is b rought into its closed goo- sition, is held against the annular edge with an inner face A 1b ther-eof.
[0160] The battery accommodating recess 15 provides a space in whi ch the battery 3 in the form of dry cells can removably be set.
[0161] With the apparatus configured as m_entioned above, bring=ing the second casing member 11 into its operm position relative to the first casing member 10 allows removing, ssetting In place and ex- chamging the cartridge 3 and the battery 4.
[0162] And, bringi ng the second casing member 11 into its close posi- tion relative to th e first casing member 10 followed by driving the motor 21 to rotate the fan 20 permits air to pass th rough the chemical impregnated body in the chemical cartridge and a ir having chemical entrained therein ®o be emanated and diffused int© an environmental atmosphere.
[0163] Further, tlhe apparatus casing body 1 even. in its closed posi- tion is itself extre mely small in thickness compar~ed with its planar size, namely thin and plate-like. Here, its planar size is as large as slightly larger tha n those of the fan 20 and the b attery 4, namely a planar size practic ally without having any area othaer than the area in which the fan 20 and the battery 4 can just be acccommodated within the apparatus casi ng body 1 (thus, omitting any useeless planar space).
[0164] Thus, the apparatus casing body 1 is made= thin and compact, permitting the bloswer type chemical diffusing apparatus to be made thin and compact.
[0165] This make s the apparatus easy to handle and renders its re- quired molds smaller in size and stock material leess in amount, thus reducing its cost of manufacture as well.
[0166] Specifically, as seen in its planar shape tlme apparatus casing body 1 comprises a first region la that is nearly ci rcular, a second re- gion 1b that is nearly rectangular and a third or mntermediate region ic interconnecting the first and second regions l.a and 1b, and as a whole is nearly rectangular except for the first region la that is nearly circular.
[0167] The first, nearly circular region la has a planar size that is slightly larger th an the outer diameter of the ffan 20, the second, nearly rectangulax region 1b has a planar size thzat is slightly larger than that of the battery 4 and the intermediate region lc is in the planar form of a p air of deltas simply to make the first and second re- gions contiguous so that there is no useless sp:ace in contour and volume of the apparatus.
[0168] As a result, the apparatus casing body 1 Chas its surface con- tour appropriately convexed and concaved, giving aesthetic accentua- tion to its overall shape and making the apparatuss visually attractive to the user.
[0169] In contrast, the cas ing body of a conventional amoparatus of this type was is monotonous in its surface contour without such an accentuation so that its ap-pearance was not much attractive to the user.
[0170] The air passages 14 can be formed not only in the first region la but also in both sides of the intermediate region lc so that chemi- cal can be emanated and diffused towards a greater numloer of direc: tions.
[0171] Mention is next made of further configurations of the appara- tus components.
[0172] The first casing mermber 10 includes an outer shell 17, an in- ner shell 18 and an inner p late 19. The outer shell 17 is dish shaped comprising a surface plate 17a provided with side plates 17b along it and formed with air passage cutouts 50 and also with a first and a second engagement section 51 and 52
[0173] The inner shell 18 ¢c omprises a base plate 18a prowided with a side plate and is fitted into the outer shell 17.
[0174] The base plate 18a @s formed with a recess 53 oper to the sur- face plate 17a of the outem shell 17. The motor 21 is r eceived and mounted in position in the recess 53 from which its outpwat shaft 21a projects passing through tke base plate 18a and has the fan 20 at- tached thereto. The fan 20 is here a sirocco fan but may be a propeller fan or the like.
[0175] The side plate 18b is provided with a plurality of draft guides 54 and also with an engagi ng section 55 for engagement with the en- gagement section 51.
[0176] The inner plate 19 has an annular reentrant 5& defining a circular opening 57 and is formed with an engaging section 58 for en- gagement with the engagement section 52 of the outer shezll 1 to cover the fan 20.
[0177] The makeup described above allows the air blo wer 2 to be readily set in position in tthe first casing member 10, namely by ac- commodating and mountingz the motor 21 in position in t he recess 53 of the inner shell 18 and fTitting the inner shell 18 in th_ is state into the outer shell 17, followed by attaching the fam 20 and then fitting the inner p late 19. Not only is this structure «easy to assemble but also it look s agreeable with the motor 21 placed out of view by the outer shell 17.
[0178] The outer shell 17 and the inner shell A8 also make the bat: tery accommodating recess 15.
[0179] The second casing member 11 is dish shaped comprising a surface plate 11b provided with a side plate 11c, which is formed with engagement section 59 that is designed to eng age with the engage- ment section 55 of the inner shell 18. The surface plate 11b has a round raised area 11d formed with the air passages 16, e. g., in the form of a pl urality of slits as shown.
[0180] The side plate 17b of the outer shell 7 in the first casing member 10 is formed midway of its length with =a cutout 17¢ while the side plate 11c of the second casing member 1 is likewise formed midway of ats length with a cutout lle, these cu touts being formed as opposed to each other to provide the air passage s 14, as shown 1n Fig. 1.
[0181] The chemical cartridge 3 includes a roumd dish-shaped recep- tacle 30 with its one side open, a disk-shaped «chemical impregnated body 31 loaded in this round receptacle 30 and a round lid 32 fitted into the latter. Here, the round receptacle 30 and round lid 32 are formed with air passages 30a air passages 32a, rmespectively.
[0182] The chemical impregnated body 31 is a cchemical carrier in the form of a shheet-like or thin disk impregnated with a chemical.
[0183] The round receptacle 30 is placed on thes annular reentrant 56 of the inner plate 19 so as to fit with and be carried by it. Then, bringing thhe second casing member 11 into its closed position places its round raised area 11d in opposition to the rownd lid 32.
[0184] Thi s sets the round receptacle 30 (and he chemical cartridge 3) in position firmly in the apparatus casing bod.y 1.
[0185] The air blower 2 and the battery 4 are s paced apart from each other in pl anar position and do not overlap in the direction of thick- ness while the chemical cartridge 3 using a chemical impregnated body or carrier in the form of a sheet is thin.
[0186] These in combination sgive rise to a blower type chermical dif fusing apparatus which as a whole is thin.
[0187] The apparatus casing body 1 so that it can be used im suspen- sion is provided on its side face with a hanger loop 60 and also in its bottom face with a hanger o pening 61, which can be alternatively used for hooking.
[0188] The hanger loop 60 ma y be formed, for example, of a U-shaped piece 62 raised from and made= integral with one of the side lates 18b of the inner shell 18 in the first casing member 10 of the apparatus casing body 1.
[0189] The hanger opening 6 1 may be formed in a nearly L-shaped attachment piece 63 raised fr om and made integral with tlme surface plate 17a of the outer shell 1.7 in the first casing member 10 of the apparatus casing body 1.
[0190] As shown in Figs. 5 amd 6, a hanger (hanging utensil) 64 may be used that has a first hooks 60 and a second hook 66 whxdch are to engage the pieces 62 and 63 for the hanger loup 65 and tlae hanger opening 61, respectively.
[0191] So equipped as menti-oned above, a blower type che mical dif- fusing apparatus according to the present invention can be carried by the user by being hung on the: hanger 64 which as shown in Fig. 5 can in turn be hung on a belt the maser wears.
[0192] Also, the use of the hanger 64 as a fall protector for the appa- ratus casing body 1 upon insesrting the hook 66 in the openi ng 61 and erecting the casing body 1 longitudinally to stand on a ssupporting plane as shown in Fig. 6 allo ws a blower type chemical diffusing ap- paratus according to the pres ent invention to be used as it rests on a floor, table or the like.
[0193] Further, a string can be tied to the hanger loop 60 ard then be used to hang the apparatus on a wall or the like or on a peart of the body or a piece of clothing of &he user.
[0194] Also, the apparatus that is thus thin and compa ct can be readily handled by any user from a child to a grownup, with its casing body attached to the waist, neck, arm or leg.
[0195] In Figs. 1 and 4, a sweitch 5 and a lamp 6 are also s hown. The switch 5 is turned on a nd off to energize and deenergize the motor 21 while turning the lamp 6 on and off, respectively.
[0196] The sheet-like carrier used as impregnated with a chemical in the present invention is illustratively made of a porous pap er, cloth, woven or nonwoven fab ric or net material. Taking its stability as it 1s placed into consideration, it is desirable that the chemical impreg" nated body for use be firmly held by a receptacle and its lid oor coating a portion, e. g., an outer peripheral portion, of the sheet-like chemical impregnated body with a resin or the like. Further, considlering its portability, it is desirable that the carrier be a thin sheet having a thickness of 2 to 5 mm and an area of 700 to 3,000 mm?2.
[0197] The chemical for use in the present invention may be an insect pest control agent such as an insecticide, miticide, vermin ox pest re" pellent, vermin growth retardant or sucking inhibitor, arormatic, de- odorant or bactericide, and should be volatile.
[0198] Such chemicals, if used to kill insects, may be a variety of volatile insecticides so far known, of which pyrethroid, carbamate, organophosphorus chermicals and so on can be listed, further of which pyrethroid chemicals can preferably be used as generally high in safety.
[0199] Further, such specific chemicals as methofluthrin, transflu- thrin, empenthrin, ter allethrin and profluthrin which are highly ac- tive and which in a small amount exhibit efficaciousness can desira- bly be used as they carn make the chemical carrier thin and small.
[0200] The power supply for the motor 21 can illustratively be one or more of dry cells such as alkaline dry cells of size AAAA, AAA, AA, C and D, manganese dry cells of size AAAA, AAA, AA, C and ID, rectan- gular-shaped alkaline cell (9 volts), lithium cells and lithitam button cells which can be used singly or in combination.
[0201] The fan 20 for use in the present invention can be a centrifu- gal fan which preferably has a size as stated below.
[0202] The centrifugal fan preferably has a diameter D of 30 mm to 60 mm. If it is smallex in diameter, then its rotation will not produce a sufficient centrifugal force, which requires larger energy t-o rotate it more rapidly and detexiorates energy efficiency. _35—
[0203] This alsso reduces the volume of the internal space that it takes, which ira turn reduces choices of the mmotor 21. Conversely, making the fan larger in D than 60 mm will maake the apparatus lar- ger in size and Dts portability poor.
[0204] The ceratrifugal fan preferably has a ratio: D/d of outer di- ameter D to inrer diameter d that is 1.05 to 1. 6. If it is smaller than 1.05, then a co-msequential reduction of a fan belade in width will not produce enough wind. Conversely, if it exceeds 1.6, then the resis: tance to rotatieon that the fan blade receives —will become excessive, again deteriora_ting its energy efficiency.
[0205] The cemmtrifugal fan preferably has an effective height of blade h ranging betw een 2 mm to 10 mm. If it is lowe r than 2 mm in height, the blade will mot have enough surface area to produce adequate wind.
Conversely, not only will a height more than 1#0 mm make the fan in- adequate to m=ake the apparatus thin but also a resultant increase in resistance to rotation will reduce its energy effi ciency.
[0206] If the rmotor is placed anywhere other than in the common in- ternal space ir which the centrifugal fan is p laced, there will be no bad influence on wind inlet but it is then required that the apparatus have a thickne=ss at the minimum that is the sum of those of the fan and motor. This has been the way adopted by the prior art, however, in failing to maake an apparatus of this type so small in both thickness and size as herre.
[0207] If the rmotor housing (i. e., the recess 53 in Fig. 2) in which the motor 21 is accepted takes more than 60 % of t he internal space taken to accept the «centrifugal fan, then the balanc e space will be 1nsuffi- cient for the famn to develop enough air flow andl operate efficiently.
[0208] Accord ingly, the motor housing (i. e., ®he recess 53 in Fig. 2) stored with thee motor 21 should be sized to takze a volume within 60 % of the internall space for the centrifugal fan to make the apparatus as a whole thin sand small in size while operating efficiently to diffuse a chemical.
[0209] This proportion, 60 %, of space occuparacy of the motor housing (i. e., the recesss 53 in Fig. 2) should preferably- be approached.
[0210] An expplanation is next given in respect of a second form of implementation of the present invention.
[0211] Referring to Figs. 7, 8 and 9, there is shown an apparatus casing body 101 having a chemical receptacle (chemical carti-idge) 102, a fan 103 and a motor 104 s tored therein whereby with th e fan 103 rotated by the motor 104 air dis drawn through air inlet ports 105 into the inside of the chemical receptacle 102 and strikes on the chemical receptacle 102 having a chem ical impregnated body impregn ated with a chemical that is an insect: pest control component). Air then en: training therein such chemicaml from the chemical impregnated body in the chemical receptacle 102 is discharged through a first andl a second air discharge port 106 and 10-7 into the outside of the casing body 101.
[0212] When the apparatus is used with the casing body 101 worn and carried by the user, air containing the insect pest contr ol compo- nent or chemical is discharg ed both through the first air discharge port 106 upwards and through the second air discharge port 107 downwards.
[0213] The first and second air discharge ports 106 and 107 are each in the form of an inclined hele having a radial length andl with an inlet 110 that lies inner and open to the fan 103 and an o utlet 111 that lies outer and open in ar outer face 101la of the casing "body 101.
In each of the first and secorad air discharge ports 106 and 107, the outer outlet 111 is defined vwith its upstream and downstir-eam side outlet hole edges 111a and 1711b while the inner inlet 110 i s defined with its upstream and down stream side inlet hole edges "110a and 110b. In each of the first and second air discharge ports 106 and 107, an upstream side guide face 1 12 connects the upstream side Zinlet hole edge 110a in the inner inlet 110 and the upstream side ouatlet hole edge 111a to each other while a downstream side guide face 113 con- nects the downstream side in_let hole edge 110b and the dowvnstream side outlet hole edge 111b to esach other.
[0214] In each of the first and. second air discharge ports 106 and 107, the upstream side guide face 7112 is inclined so that the upsti—eam side outlet hole edge 111a lies dowsnstream of the upstream side inlet hole edge 110a, the guide face 112 being preferably arcuate.
[0215] In each of the first and. second air discharge ports 106 and 107,
the downstream seside guide face 113 is immclined so that the dowrn- stream side outlett hole edge 111b lies down stream of the downstream side inlet hole edgze 110b, the guide face 113 being preferably arcuate.
[0216] The upstream side inner hole edge 110a in the first air d is charge port 106 (e. g., the upstream side acir discharge port) and t-he downstream side i.nner hole edge 110b in the second air discharge port 107 (e. g., the downstream side air discharg e port) lie preferably close to, and more prefferably also act as, the downstream side inlet hole edge 110b in the second air discharge port B07 and the upstream si. de inlet hole edge 11a in the first air discharg-e port 106, respectively.
[0217] Here, the terms “upstream” and “do-wnstream” are used in ke" lation to the direcstion in which the fan 103 1 s rotated.
[0218] Also, the t erm “inclined” is used to ®he state of being inclin ed to a radial direction.
[0219] In other wwords, the first and seconed air discharge ports 1 Ob and 107 are each din the form of a hole inclirmed to a direction of rotza- tion of the fan.
[0220] With the mmakeup described above, t-he rotation of the fan 1403 causes air to issue= forcibly through the first: and second air dischar ge ports 106 and 107 as indicated by the arrowss a and b.
[0221] Thus, whe_n the apparatus is used =with the casing body 1€1 attached to the waist of a user, air containing an insect pest control component is allovved to issue forcibly towar=ds his/her head and feet.
Since the insect peest control component is t herefore allowed to reach the head and feewt quickly, it is possible ®to protect the user from harmful insects im mediately after the apparaatus begins to be used.
[0222] Mention is next made of specific comfigurations of apparatws components.
[0223] The apparaatus casing body 101 comporises a base member 1220 and a cover memb er 121 removably attachecd thereto and is provided with a fan, a chemmical and a motor accommodating chamber 122, 1223 and 124.
[0224] The fan acecommodating chamber 122 is round in which a fan 103 is rotatably meounted. The fan accommodating chamber 122 has a round peripheral face 122a in which are opem the first and second a ir
0 discTharge ports 106 and 107, or their re=spective inner inlet s 110. [022 5] Communicating with the fan ac commodating chamber 122, the chemical accommodating chamber 123 i_s opposed and defin ed with the cove ¥ member 121, the cover member 121 being formed with the air inlet ports 105. [022 6] The motor accommodating charmber 124 is formed in the base member 120 by opening in its rear fac-e 120a and is partitioned from the #fan accommodating chamber 122 by a wall of the base mmember 120, thro ugh which the output shaft 104a of a motor 104 is passsed project" ing finto the fan accommodating chamb er 122 wherein it iss coupled to the #an 103. : [022 7] Also lying in the base member B20 is a battery acco. mmodating sect@mon 126 that is formed so as not teo open the fan acco mmodating chamber 122 and further not to over lap the motor acco mmodating chamber 124 in the direction of their thicknesses.
The “battery ac- commnodating section 126 is formed in the base member 1 20 as a re- cess open to its rear face 120a and spa tially continuous with the mo- tor smccommodating chamber 124. [022 8] In this battery accommodating section 126, typicaally in two compoartments thereof disposed as showwn across the motom accommo: datimng chamber 124 are accepted two battery cells 127, respectively. [022 9] With this battery or these batteery cells 127, the m_otor 104 1s ener gized and driven. [023 0] With the casing body 101 constructed as mentionecd above, its thiclksness H can be minimized since the battery 127 and the motor 104 can mo longer overlap in its thickness dmrection. [023 1] Further, the motor accommodatting chamber 124 amd the bat- tery accommodating section (recesses or compartments) which are open in the rear face 120a of the base member 120 can be with their cap or caps for closure. [023 2] The casing body 101 is also provided in its base mmember 120 with a hanger loop 128 and a hanger ho le 129. [023 3] The hanger loop 128 as shown. in Fig. 7 enables the casing body- 101 to be hung on a hanging ute nsil 130 which can in turn be attached to or clipped on a user’s belt or the like in use of the appa-
ratus.
[0234] The hanging utensil 130 as shown in Fig. 10 has at its one end a hook 131 that can engage the hanger loop 128 to hosok the casing body 101 on the hanging utensil 130, which has at its other end an- other hook 132 that can be fitted into the hole 129.
[0235] With the hook 132 fitted in the hole 129 as shown in Fig. 7, therefore, the utensil 130 when oriented to stand as inclicated by the imaginary line with the hook 131 placed in contact witln a supporting plane such as a table can also be used to support the cassing body 101, namely the apparatus placed on thereon.
[0236] Of course, the app aratus can also be used with the rear face 120a of the base member 120 placed on such a supportingg surface.
[0237] The chemical receptacle 102 as shown in Fig. 1 1 comprises a round dish-shaped receptacle 140 with its one side op en and has a disk-shaped chemical impregnated body 141 loaded in his round re- ceptacle 140 and a round lid 142 fitted into the latter. Heere, the round receptacle 140 and round lid 142 are formed with air yoassages 140a air passages 142a, respecti vely.
[0238] The chemical impregnated body 141 is a chemi_cal carrier in the form of a sheet-like or thin disk impregnated with a echemical.
[0239] The round receptacle 140 is placed on the annular reentrant 143 formed in a front face 120b of the base member 1220 so as to fit with and be carried by it.
[0240] As mentioned above, the chemical receptacle 102 using a chemical integrate body 1 41 in the form of a sheet-likze carrier im- pregnated with an insect p est control component is thin and can make the apparatus casing body 101 small in thickness H.
[0241] Mention is next ma de of further details of the fir-st and second air discharge ports 106 and 107.
[0242] Referring to Fig. 8, the fan 103 has its outer pesripheral face 103a which is preferably spaced from the upstream side inlet hole edge 110a by a distance A yanging from 0.1 mm to 5 mm.
[0243] The fan 103 has its center 103b which is prefeerably spaced from the upstream side in let hole edge 110a by a dista nce R having relationship: r = 1.05 X R ~ 2.5 X R where r is distzance between the center 1033b of the fan 103 and the upstream side ovatlet hole edge 111a.
[0244] This c¢ onverges wind flows produc ed by rotation of the fan 103 to converge efficiently in the first and se cond air dischaarge ports 106 (through thes e flow paths) and 107, thereby causing -air containing the insect pe st control component to bee forcibly disc:harged there: through.
[0245] To wits, although it is desirable ora the one hand. that distance
A approach A = 0 infinitely, on the other hand if A < O.1 mm it then becomes diffic ult to control accuracy of tke members of which the ap- paratus is maade. Then, an inaccuracy vill produce am interference between the f=an 103 and the upstream sicde inlet hole edge, which can be avoided omrly at a significant additional cost them required to achieve due precision.
[0246] Convewsely, if A > 5 mm, the wimd by the fan 103 will then tend to be led. less into the first and sec ond air discha._rge ports 106 and 107 and rather pass round the region s of distance A and circulate almost within the fan accommodating ch amber 122. Tkaen, the wind will be lost of its force there with a consequent loss of diffusion effi- ciency.
[0247] Also, iX r < 1.05 x R, then the width of the first a_nd second air discharge port s 106 and 107 will become s © small that th e wind by the fan 103 while passing through them suffer-s a pressure lo ss.
[0248] Conver-sely, if r > 2.5 x R, then th e width of the first and sec- ond air discha.rge ports 106 and 107 will become so largzge in that the wind by the fzn 103 spreads out suddenly there, losing its pressure again with a consequent loss of diffusion e fficiency.
[0249] Here, the term “width of the firs t and second .air discharge ports 106 and 107” is used to mean the rradial distance between the inner inlet 110 and the outer outlet 111.
[0250] While t=he first and second air discharge ports 106 and 107 are typically constructed as mentioned above to have an ide ntical air re- sistance to discharge an identical air flo w therethroug h so that an identical amou nt of the insect pest control component maay be emitted towards both tlhe user's head and foot regi.ons, it may be desirable de-
pending on a place of use to emit more of it towards one of tlnese re- gions than towards the ot her.
[0251] Then, the air resistance of a selected one of the first &and sec: ond air discharge ports 1906 and 107 can be made smaller than that of the other to cause air eratraining more in amount of the insect pest control component to be emitted through the selected air di scharge port into the outside air. Alternatively, a third air discharge peort may additionally be formed in the base member 120 through w hich to cause air containing the insect pest control component to be emitted towards upwards or down wards.
[0252] For example, in a amodification here as shown in Fig. 12 a first, a second and a third aix discharge port 106, 107 and 108 may be formed as angularly spaced apart by an angle of 120° in a —vertical plane such that air is em itted through the first, second and third air discharge ports 106, 107 and 108 upwards, downwards and ololiquely upwards as indicated by t he arrows a, b and ¢, respectively. : [0253] This modification therefore permits the insect pest component to be emitted more upwar ds.
[0254] Should the apparatus be designed to cause the inse ct pest control component to be emitted more downwards, the third exhaust port 108 can be so arranged and configured as to discharge air obliquely downwards. For example, the apparatus can take a position vertically opposite to that shown in Fig. 12.
[0255] While only the fimst and second air discharge ports 1 06 and 107 or the first, second armd third air discharge ports 106, 107 amnd 108 are shown above to be provided, the apparatus especially wken de- signed for use as worn on. the waist may be formed with a sub sidiary air discharge port or por ts to direct air laterally thereof wheere the insect pest control component may become deficient so that. air is emitted in all directions w=ith upwards and downwards inclusive.
[0256] For example, subsidiary air discharge ports 109 facing later- ally right and left sides may be formed in a second modification here as shown in Fig. 13.
[0257] Such a subsidiary air discharge port 109 is substantially iden- tical in shape to but large rin air resistance than the first and second air discha rge ports 106 and 107 ment@oned above. For examp le, it is less open in the direction of rotation of the fan and less in the amount of air discharged and less energetic th an the first and second air dis- charge poxts 106 and 107.
[0258] Thaus, the sizes in the rotatio n of the fan between —the up- stream sicle inlet hole edge 110a and sthe downstream side inlet hole edge 110b and between the upstream side outlet hole edge 1X 1a and the downsstream side outlet hole edge 111b in the subsidiary air dis- charge pomt 109 are smaller in than th-ose in the first ands second air discharge ports 106 band 107.
[0259] Simce this allows air containin.g the insect pest contr ol com- ponent to be discharged laterally towa_ rds the right and left sides as indicated by the arrows d and e, the insect pest control compon ent can be emitted laterally of the user's waists, as well as towards the user’s head and Feet.
[0260] Ore or two such subsidiary air discharge ports 109 may be provided on only one or both of the ri ght and left hand sides of the user's waisst.
[0261] In effect, there need be no limmtation imposed on the mumber of subsidiary air discharge ports as merationed above.
[0262] Th e total number of air dischamge ports 1s preferably at most six, includ.ing two main air discharge ports in the up and dow n sides (first and air discharge ports 106 and 1-07) or three main air discharge ports in tkree sides (first, second and third air discharge ports 106, 107 and 108) and one or more subsidiar y air discharge ports 10 9. That will be sufficient to cover insect pest control effects in lateral direc: tions and more than that will merely weaken the power of air up- wards and downwards.
[0263] To prevent entry of contaminamnts through the first, second and third air discharge ports 106, 1077, 108 and subsidiary air dis- charge ports 109, a plurality of curremt plates may be provided for these air discharge ports, which are preferably oriented horiz ontally parallel to wind flows and mutually spamced apart by a distance of 1 to mm.
[0264] Ea ch such current plate is preferably shaped rectangu lar, el-
liptical or in the form of a water drop or any other that does raot im- pede wind flows.
[0265] The chemical fox use in the present invention may be z= mitl cide, vermin or pest rep ellent, insecticide, or vermin growth ret ardant or sucking inhibitor, and should be volatile.
[0266] Such chemicals, if used to kill insects, may be a vardety of volatile insecticides so far known, of which pyrethroid, carbamate, organophosphorus chem icals and so on can be listed, further of” which pyrethroid chemicals c an preferably be used as generally high in safety.
[0267] Further, such specific chemicals as methofluthrin, transflu- thrin, empenthrin, tera llethrin and profluthrin which are highly ac" tive and which in a sm all amount exhibit efficaciousness can «desira- bly be used as they can make the chemical carrier thin and small
[0268] The sheet-like c arrier used as impregnated with a chemical in the present invention is illustratively made of a porous paper, cloth, woven or nonwoven fabwxic or net material. Taking its stability =as it 1s placed into consideration, it is desirable that the chemical immpreg- nated body for use be fixmly held by a receptacle and its lid or coating a portion, e. g., an outew peripheral portion, of the sheet like chemical impregnated body with a resin or the like. The receptacle and 13d may be composed of a matewial such as polyethylene terephthalate , poly- propylene, polyethylene , polyacetal, nylon, acrylic, ABS, paper, AS or metal. Further, considering its portability, it is desirable th at the carrier be a thin sheet having a thickness of 2 to 5 mm and an area of 700 to 3,000 mm?2.
[0269] Especially, nomwoven fabric is suitable, prefera bly a “metsuke” (mass per umnit area) of 10 g/m? and more preferably 20 to 50 g/m?2. If it exceeds 1 00 g/m2, then the chemical impregnate d body will become too large in air resistance to pass the wind by the fan and to diffuse the chemical smoothly. Conversely, it is smaller tkhan 10 g/m2, the chemical in ammount that can be retained in the ch_emical carrier will be too little and soon become short of supply to justify its manufacture.
[0270] The fan may be a centrifugal fan such as a sirocco fan, radial fan or turbo fan.
[0271] The fan should be rotated at a rate of rotation o f preferably 500 to 4,000 rpm and more prefexably 700 to 3,000 rpm.
[0272] The centrifugal fan should have a diameter preferably of 20 to 100 m m and preferably 30 to 60 mm. It should have a hei ght prefera- bly of 2 to 50 mm and more preferably 5 to 20 mm.
[0273] The fan, especially sirocco fan or radial fan, should preferably have am number of blades of 10 to 50.
[0274] The power supply for dri ving the fan can illustrat ively be one or moxre of dry cells such as alka line dry cells of size AAAA, AAA, AA,
C and D, manganese dry cells of size AAAA, AAA, AA, C and D, rec- tangular-shaped alkaline cell (9 volts), lithium cells and Rithium but- ton ce lls which can be used single or in combination. A plurality such dry ce 1ls can be used connected xn series or parallel. A secondary bat- tery caan also be used preferably equipped with an AC adapter for re- charging by a domestic power supply (at AC 100 volts).
[0275] The casing body 101 cam be attached to the user not only by the ha_nger as shown but also in any way such as by means of a clip or with which to hang the apparatus on or a hole formed thirough which a belt or strap can be passed to attach the apparatus on a region of the us er’s feet, waist or the arms.
[0276] The casing body 101 can be equipped with a switcEka to turn on off energizing the apparatus and also with an indicator of LED, neon lamp oor liquid crystal type for displaying the apparatus being ener- gized. Further, the fan itself cara be made visible from the outside so that tlhe state of the apparatus being energized can be se en from the fan rotating.
[0277] It should also be advantageous to set both the battery and chemiccal impregnated body in the chemical receptacle t o end their suppli es simultaneously. Then, the battery and the chemi cal recepta- cle cam be mounted in a cartridge so that they can be re placed as a body, thereby improving the expediency of the apparatus in mainte- nance.
[0278] Conversely, if the batters and the chemical impregnated body are not made ending simultaneously, then it should be desirable to make the respective endpoimts of the battery and the chemical 1m" pregnated body in the chermical receptacle indicated by being dis played individually.
[0279] While the casing body 101 (base member 120) is shown above as its peripheral region forming the fan accommodating chamber 122 is larger in thickness to form the air discharge ports, this is not a limitation.
[0280] For example, a region of the casing body 101 that is outer to the fan accommodating chamber 122 is formed with a plurality of guide blades circumferentially spaced apart such that interstices be- tween these guide blades form air discharge ports.
[0281] A substitute battery accommodating chamber or chambers may be provided in a region or regions lateral of the casing body 101 and to the base member 120.
[0282] Although the foregoimg description implies the user primarily : as a human being, the term is here applicable to a pet such as a dog or livestock such as a cow. Jn this case, a front to back region of it from its head to tail or from its face to belly and rear feet is an area of interest to which the insect p est control component is to be directed.
[0283] An explanation is next given in respect of a third form of im- plementation of the present 1 nvention.
[0284] As shown in Figs. 14, 15 and 16 a blower type chemical dif- fusing apparatus according to this form of implementation of the in- vention includes a chemical receptacle (chemical cartridge) 201 and an air blower 202. It further comprises a main casing body 205 having an air intake port 203 through which air is drawn by the air blower 202 and an air discharge port 204 through which air entraining therein a the chemical volatilizing from the chemical receptacle 201 is emitted; a power casing body 208 separated from the main casing body 205 and containing a power source 207 for the air blower 202 in the main casing body 205; a nd an electrical cord 209 connecting be- tween the main casing body 205 and the power casing body 208 for energizing the air blower 20 2 in the main casing body 205 from the power source 207 in the powe r casing body 208.
[0285] More specifically, the main casing body 205 is in the form generally of a circular cylinder that is axially short. And, it forms the air inlet port that is largely open upw ards while forming th e air dis charge port 204 which is open in the form of a plurality of sl-ts in one of its side facees. It should be noted he re that the number off such air discharge por#ts and the size and shap e of each of such air inlet and outlet ports arse not limited to those shown and described.
[0286] And, the main casing body 205 has in its inside and b-eneath it the air blower 202 positioned. The air blower 202 comprisess a motor 211 and a sirocco fan 212 as a sort of the centrifugal fan wh erein the motor 211 hawing its output shaft cormnected to the fan 2122. The si- rocco fan 212 has a number of slantimg blades 213 circumferentially equidistantly spaced apart, which are rotated by the motor 211 to draw air thro—ugh the air inlet port 203 at the top of the si rocco fan 212 to cause =air drawn to flow centrifugally within the ma in casing body 205 and to emanate through the air discharge port 204 from the side face of tthe main casing body 205 . However, the use he=re of the sirocco fan 21 2 being a sort of the certrifugal fan as the a ir blower 202 is not a liomitation but any other suitable fan such as, for- example, a propeller fara having an impeller in the form of a propeller about its axis may be ussed. When such a propeller fan is used as the blower fan, the main casi ng body 205 may be foramed at its bottom with an air passage hole serving as an air inlet port and may use the albovemen- tioned port 20@3 as an air discharge port. And, adjacent to tche latter there may, as mentioned below, be disposed the chemical r eceptacle 201 charged w~ith a volatile chemical s« that air drawn by tle blower fan through fthe air inlet port at tlwe bottom passes threough the chemical receptacle 201 at the air discharge port across thae blower fan and upon entraining therein the volatilizing chemical to i.ssue into the outside.
[0287] The clhemical receptacle 201 charged with the chennical and disposed as shown within the main ca sing body 205 is fitted with a region of the mmain casing body 205 defining the air inlet po rt 203 at its top so thats it lies above the air blower 202. As shown ims Fig. 17, the chemical receptacle 201 is round amd small in thickness and com- prises an uppeer and a lower member 2214 and 215 which to accept a chemical carrier (chemical impregnated body) between them and are fitted together. The upper and lower members 214 and 215 are for med with large apertures 217 amd large apertures 218, respectively, through which air passes to cause chemical contained in the chemical carrier 216 to volatilize.
[0288] The volatile chemical wzith which the chemical carrier is t o be impregnated in the chemical receptacle 201 is a chemical that serves as an insecticide, repellent, ar omatic, deodorant, germicide or fu ngi- cide. Such chemicals, if used to kill insects, may be a variety of v—ola- tile insecticides so far known , of which pyrethroid, carbamate, or: ganophosphorus chemicals and so on can be listed, further of wiIhich pyrethroid chemicals can preferably be used as generally high in safety. Further, such specific chemicals as methofluthrin, transflu- thrin, empenthrin, terallethrirm and profluthrin which are highly ac- tive and which in a small amo unt exhibit efficaciousness can desira- bly be used as they can make the chemical carrier thin and small.
[0289] Also, the chemical receptacle 201 and the chemical carrier 216 are not limited to types as described but may be any ones suitabl e to retain a volatile chemical. For example, the chemical carrier 216 may not only be in the form of a she et but also may be in the form of a met, lattices, a honeycomb, a flocculate, a sponge and may be large number of particles which are impregnated with a chemical. Further, the chemical receptacle 201 need riot be one in which a chemical car rier 216 impregnated with a chemical is retained but may be one which itself is made of a hard sponge or foamed body and impregnated wvith a chemical, namely which itself retains the chemical therein. Such a chemical receptacle 201 may be of any suitable shape and of any suitable material as desired.
[0290] The main casing body 205 is formed at its lower face with a fitting 219 for attaching theret o a fitting means 206 that enables the main casing body 205 to be fitted onto an object wherein the fitting 219 is here in the form of a thin and elongate hole extending in_ its depth across a full length of the casing main body 205.
[0291] Then, the fitting means 206 that enables attaching the main casing body 205 to an object is attached to the fitting 219 which has a thin hole passing through the main casing body 205. The fitting me ans 206 is here in the form of a flexible and elon gate belt 221 which with a buckle had at its one end can be worn on & user's wrist.
Th is wearing belt enables the main casing body 205 for the subject blower type chemical diffusing apparatus to be fitted to a user's wrist or the like for its use.
[0292] The fitting means 206 shown by the wearing beelt 221 is not limited to that described but may have a length ranging from several centimeters that enables its fitting around a user's wristc or the like to 1 Or 2 meters suitable for fitti ng around a user’s waist o r any suitable supporting object and thus may be of a length as desire d. It may also take any of a variety of form s including a belt, band a_nd string. Its material is not limited but m aay be any known suitable material such as synthetic resin, leather, cl oth, textile and rubber. Tle attachment means used for the wearing belt 221 need not be a louckle 222 as shown but may take a button form, hook form, a plug-i:mn belt form, a
Hook-and-Loop fastener (e. g_, “magic tape” [registered trade markl) form or the like.
[0293] Further, the fitting m eans 206 need not be limisted to a wear- ing belt 221 as shown but may take a form of a belt to be worn around a Leg, a hook 223 for hooking at a belt worn on a pant eor at a pocket as shown in Fig. 18, or a forma of pin or clip to be attacked directly to clothing.
[0294] The power casing body 208 includes the power source 207 for the air blower 202 in the main casing body 205 and is separate from the main casing body 205. The power source 207 included in the power casing body 208 is a battery 224. The power casing bod-y 208 is a box of a size that is the minimum for accepting the battery 224 required, forr example, comprising two dry cells. The battery 224. other than a dry cell or cells may be a rechargeable battery. Separat ing the power casing body 208 from the main casing body 205 allow—s making the power casing body 208 larger in size so that the battery 224 larger in size and dry cells 224 larger £n number can be used acceepted therein.
Thuis in turn permits increasimg the voltage that can be applied to the main casing body 205 so as to make the output power of the air blower
202, e. g., the: strength of the driven fan, finely acljustable while making the subject blower type chemical diffusing ap paratus usable over a prolonge=d time span.
[0295] The powwer casing body 208 may also be adapted so it can have a fitting meanss 206 attached thereto that enables it to be an object.
The fitting me ans 206 may, here too, be a wearing belt 221, a hook 223, or a pin or" clip as mentioned above.
[0296] The co upling cord 209 extending between thae main casing body 205 and #&he power casing body 208 to connect them together is an electrical cord for electrically energizing the air blower 202 in the casing main bosdy 205 from the battery 224 as the power source 207 in the power casimg body 208. The connection cord 209 sh ould preferably be made as small in diameter as possible. The connection cord 209 may optionally= be provided midway or at its one end with a take-up mechanism to make its length adjustable.
[0297] In Fig- 19, the connection cord 209 is showr also provided with a fitting rmeans 206 that enables itself to be attacthed to an object.
The fitting me:ans 206 here is an attaching member 22-5 that may be a
Hook-and-Loop fastener tape (e. g., a “magic tape” - registered trademark) at-tached to the connection cord 209 at i ts midway and having surface irregularities to enable the member to stick to clothing or the like. Thee attaching member 225 is, of course, not limited to this particular exa mple but may be a safety pin or a clothespin or any other suitable means that can make the connection coord 209 clinging to clothing or tthe like.
[0298] The coennection cord 209 may be adapted to make itself de- tachable from the main casing body 205 or the power casing body 208 or both.
[0299] With t he connection cord 209 made detachablee from both the main casing body 205 and the power casing body 208, =as shown in Fig. the main c.asing body 205 may be provided on its sside face with a pin 226 projec.ting therefrom and the power casing body 208 provided in its side faces with a jack 227 recessed therein. Then , the connection cord 20 may Me provided at its one end with a jack 228 and at its other end witlh a pin 229. This permits the main casirg body 205 and the power casing body 208 which are normally conrmected together via the connection cord 2 09 for use of the apparatus to be used in the state that they are directly connected together dep-ending on particu: lar circumstances of their use.
[0300] In an example of the use of the blower type chemical diffusing apparatus constructed as mentioned above, the man casing body 205 is fitted to a wrist, le g or waist portion of the bod= of a user via the wearing belt 221. On the other hand, the power casing body 208 is accepted in a pocket of clothing or a pant of the wmser or attached to the user's waist via a mother wearing belt 221. Them, the main casing body 205 and the povewer casing body 208 are conn ected together via the connection cord 209 and electric current is p=assed to the main casing body 205 from the power casing body 208 via the connection cord 209 to operate the air blower 202 in the maim casing body 205.
Then, the air blower 202 in the main casing bosdy 205 draws air through the air inlet ports 203 and causes air dravvn to pass through the chemical receptacle 201 included in the main casing body 205 and air entraining thereirm chemical volatilizing from t"he chemical recep" tacle 201 to emanate and diffuse laterally into tlhe outside through the air discharge portss.
[0301] With a blowe r type chemical diffusing apparatus which as mentioned above comprises a main casing body 205 whereby air drawn by an air blower 202 is emanated togethe r with a chemical volatilizing from a clwemical receptacle 201 and eratrained therein, a power casing body 208 separate from the main casing body 205 for accommodating a batt-ery 224 as a power supply 20° for the air blower 202, and a connectiora cord 209 for connecting the main casing body 205 and the power casing body 208 to each othew, the main casing body 205 is rendered small in size and light in weight by virtue of the fact that the power casing body 208 containing the battery 224 as the power supply 207 tha tis the weightiest of componeants of the appara- tus is made separates from the main casing body 205 and that the main casing body 205 is allowed merely to contai n the chemical re- ceptacle 201 and the air blower 202. This allows a user, for example, to fit the main casin g body 205 of the subject blower type chemical _5]—
diffussing apparatus on its wrist or the like using a wearing b elt 221 and t-o store the power casing body 208 in a pocket of its clothi.ng and then to use the apparatus comfortably wi thout feeling disagmreeable with the size and weight of the apparatus.
[0302] Also, since the main casing body 205 and the power casing body 208 which are separated from each o ther are used in th e state that they are connected together via the connection cord 209, even if eithe r the main casing body 205 or the powver casing body 208 in use happ-en to fall upon detaching from the use r’s body on which tEaey are worn , the connection cord 209 coupling them together prevent-s them from being lost together.
[0303] Also, making the connection cord 209 removable from the main casing body 205 and the power casings 208 allows the conection cord 209 in the use of the apparatus after e ither the main casirg body 205 or the power casing body 208 is fitted onto the user’s bod y to be connected to it, thereby facilitating its fittizng onto the user’s body.
[0304] Further, providing the main casing body 205, the power~ casing body 208, the connecting cord 209 or each of two or all of them with a fittin_g means 206, e. g., a wearing belt 221, a hook 223, a pin o xr a clip, that enables the same to be fitted on any supporting object as desired allow=s the subject blower type chemical diffusing apparatus to be eas: ily fi tted onto any desired part of the use r's body or any oth-er sup- porti ng object.
[0305] The blower type chemical diffusing apparatus accordingz to the present invention is not limited to the particular forms of impo lemen- tation illustrated above. For example, while the battery 224 corntained as th e power source 207 in the power casingg body 208 is illustr ated as comp rising a dry cell or cells, it may be a solar cell or cells. Should a solar cell or cells be used as the power sou rce 207 or the batte ry 224, the subject blower type chemical diffusing apparatus may be mised as show n in Fig. 21 upon sticking the power casing body 208 omto the brim of a hat the user wears or a shoulder or the like of the use r while fittimmg the main casing body 205 onto a wrist of the user by m eans of the wearing belt 221.
[0306] Also, the subject blower type chemical diffusing appara tus can be used not only by a human being. For example, it may be used on a pet such as a dog. In this case, as shown in Fig. 22 the main casing body 20.5 may be fitted to a collar 231 of the pet by means of the fit ting me=ans 206 such as a hook and the power casing body 208 fitted onto a wvrist or the like of its owner. T hen, a connection cord 209 to extend between the main casing body 2 05 and the power casing body 208 may be put together with a lead 232 to extend between the pet's collar 2531 and a owner’s hand to form a cord incorporated lead for use on a pet ..
[08307] .Also, while in the forms of implementation described above, the fitting means 206 is shown as necessarily attached to the main casing body 205, this is not a limitatio n. A fitting means 206 as de- scribed may be attached to each of the main casing body 205, the power c=asing body 208 and the connect3on cord 209 or one or each of two of them. It is also possible to provide a subject blower type chemica 1 diffusing apparatus omitting the fitting means 206.
[0308] Also, while in the forms of implementation described above, the maim casing body 205 is shown as maving the chemical receptacle 201 disposed adjacent to the air inlet ports 203, the chemical recepta- cle 201 omay be disposed adjacent to the air discharge ports 204 when equippeed with a suitable mounting meams therefor. Further, it is pos- sible to provide a chemical receptacle 201 for each of the air inlet and air disc harge ports 203 and 204. It is also possible to disposed a chemica 1 receptacle 201 at an inner or outer peripheral side of the si- rocco fam 212 and then to integrate the chemical receptacle 201 with the air blower 202, or to have the sirocco fan 212 in the air blower 202 carry a chemical and to make it removable, or to attach or dispose a chemica 1 receptacle 201 in the form of a porous sheet at the front of a large ntamber of blades 213 in the siroc co fan 212 and to make it re- movable .
[0309] -An explanation is next given in respect of a fourth form of im- plement ation of the present invention.
[0310] “While with reference to Fig. 25 a chemical cartridge of the present invention will, as an example of its use, be described as ap- plied to a blower type chemical diffusing apparatus using a chemical cartriclge to diffuse a chemical into ar atmosphere, it wi ll be under: stood —that the present invention wher applied is not linnited to this particwmalar use.
[0311] As shown in Fig. 25, a main cemsing body 301 is pmovided with an alr blower 302 and has a chemical cartridge 303 re-movably at- tached thereto wherein a fan 304 of th e air blower 302 is rotated by a motor 305 to pass air through the chemical cartridge 303.
[0312] The main casing body 301 incl udes a base member 310 and a cover member 311, is formed with a bl ower mounting secstion 312 and a batt ery accepting section 313 and h as an air inlet secttion 314 and an air discharge section 315.
[0313] The air blower 302 has a fan 3 04 and a motor 305 mounted in a hou sing 306 provided in the blow er mounting section 312. The housirag 306 has an air inlet port 306a communicating —with the air inlet section 314 and also has an air discharge port (not shown) com- munic ating with the air discharge sectaon 315.
[0314] A battery 307 shown as comprising two dry cells is attached into the battery accepting section 313.
[0315] The cover member 311 is so coranected to the main casing body 310 tha at it can be opened and closed whereby opening thes cover mem- ber 31.1 allows the chemical cartridge 303 and the batte ry 307 to be remov ed and fitted in.
[0316] The chemical cartridge 303 is adapted to accept: a chemical carrie or impregnated body 320 in the form of a porous oer air perme- able aind liquid absorptive sheet impregnated with a claemical, and has a retainer or retainer receptacle 3821 for retaining the chemical impregznated body 320.
[0317] In other words, since the ch emical impregnate d body 320, which is in the form of such a sheet, seo liquid-absorptive and so weak in stiffness that it cannot sustain itse 1f and if it is held «directly by a hand, a chemical therein may adhere to the hand, it is “held along a portiom thereof with the retainer rece ptacle 321 to cause air to pass througzh other portions thereof.
[0318] So configured and arranged, th e chemical cartridgze 303 can be made thin because the chemical carrier or impregnated body 320 is here thin and the retainer receptacle 321 can be made thin.
[319] Therefore, using such a chemical cartridge 303 allows thin- nAng a blower type chemical diffusi ng apparatus as described.
[0320] The retainer receptacle 321 includes a holder section 321a holding upper and lower faces of the chemical impregnated body 320 fr-om up and down and an air flow section 321b through which air fl ows. [®321] Between the holder section 321a and the chemical impreg" n=ated body 320 there is formed a s pace 321c, which is open to the out" si_de through a vent section 321d formed in holder section 321a so that alr may be passed through the space 321c. [©322] Preferably, the holder sec tion 321a is formed with a recess w here it is contacting the lower face of the chemical impregnated body 3=20 and the space 321c is formed between this recess and the lower famce of the chemical impregnated body 320. And, the holder section 3=21a where it is contacting the upper face of the chemical impreg- nated body 320 is formed with vent holes constituting the vent section 3=21d and through which the space 321c (recess) is open to the outside.
[323] So constructed, the retaimer receptacle 321 can retain the chemical impregnated body 320 im the form of a sheet while main- taining its shape and can be held with a hand without the fear that chemical may contaminate the han d. [™324] Also, while chemical in a xegion of the chemical impregnated beody 320 where it is held by the h older section 321a is no volatilizing w- ith air flow since air flow is pre vented there, the chemical there is still volatilizing into the space 32 Ec and from the latter to the outside tkarough the air flow section 321b and thus allowed to emanate and d-iffuse into the environmental atmosphere. [D325] While mention is specifically made below of the retainer re- ceeptacle 321 as regards its possible shape, it should be understood tkat this is by way of example only and not limiting the same.
[326] The retainer receptacle 321 as shown in Figs. 25 to 31 com- prises a receptacle body member 330 and a receptacle cover member 3 40 by and between which the che mical impregnated body 320 1s held amd retained.
[0327] The receptacle bo dy member 330 has a central smupport section 331, a peripheral suppoxt section 332 spaced from an.d around the central support section 330 and a plurality of interme=diate support sections 333 connecting t he peripheral support section 3 32 to the cen- tral support section 331 wherein a space defined wit h the central support section 331, the peripheral support section 332 and neighboring intermediate support sections 333 connecte=d together by the peripheral support section 332 is open constitutin g an air flow section 334.
[0328] The central support section 331 has its upp er face 33la formed with a recess 335 where it is contacting the low-er face of the chemical impregnated body 320 and forming the space 3=21c elsewhere where it is opposed to the lower face of the chemical impregnated body 320.
[0329] The peripheral support sections 332 have its up per face 332a formed with an annular recess 336 where they are ceontacting the lower face of the chemical impregnated body 320 and. forming the space 321c elsewhere thew are opposed to the lower face of the chemi- cal impregnated body 320.
[0330] The intermediate support sections 333 have thei_r upper faces 333a formed with recesses 337 where they are contactmng the lower face of the chemical impregnated body 320 which recessses communi- cate between the recess 8335 and the annular recess 336, the upper faces 333a forming the space 321c elsewhere where thew are opposed to the lower face of the ch emical impregnated body 320.
[0331] The receptacle cover member 340 has a central hold section 341, a plurality of peripheral hold sections 342 spaced arad around the central hold section 341 and a plurality of intermediate hold sections 343 connecting the perip heral hold section 342 to the central hold section 341 wherein a spa ce defined with the central hold section 341, the peripheral hold section 342 and neighboring interamediate hold sections 343 connected together by the peripheral sectiomy 342 is open constituting an air flow section 344.
[0332] The central hold section 341 is identical in size too the central support section 331 and has a vent hole 345 opposed to thae recess 335.
[0333] The pe=ripheral hold section 342 is identical in size to the p e- ripheral support section 332 and has a vent hole 346 opposed to the annular recess 336.
[0334] The in termediate hold sections 343 ar—e identical in shape ard size to the instermediate support sections 33 3, and the air flow se c tions 344 are Opposed to the air flow sections 334 so that air smooth ly flows through both the air flow sections 334 and 344. The intermedi ate hold sections 343 are formed with vent h_oles 347 so they are oTp- posed to the rezcesses 337, respectively.
[0335] The receptacle body member 330 amd the receptacle coveer member 340 awe detachably attached together .
[0336] In the form of implementation illu strated, the peripher.al support sectiom 332 has its outer edge raised from its upper face 332a to form a raised rim 332b in the form of a rintg in which is the chem 1 cal impregnatesd body 320 and then the receptacle cover member 3410 fitted.
[0337] As an alternative to this attachment d_esign, the cover membear 340 may be for-med with such a raised rim whiich can be fitted over tine outer edge or rim of the peripheral support s ection 332 to attach the cover member 340 to the receptacle body member 330. Yet altern=a- tively, the rec eptacle body and cover membe-rs 330 and 340 may loe provided with a pin and a hole which can be mmated with each other #®o attach these m embers together.
[0338] Also, wvhile in this firm of implemen tation the intermediate support and heold sections 333 and 343 are ezach shown comprising a plurality of sulbsections extending radially, noot only may such subsea: tions if adopte d be in the form of a lattice bumt also each section 3333, 343 may, for example, comprise a porous plate or the like.
[0339] So consstructed and arranged as mentieoned above, the retainer receptacle 321 acts to hold and support the chemical impregnate-d body 320 by supporting and holding a central region thereof with an d between the cesntral support and hold sectionss 331 and 341, a periph: eral region the-reof with and between the peripheral support and hol.d sections 332 a.nd 342 and an intermediate r-egion thereof with an d between the in termediate support and hold secctions 333 and 343.
[0340] This al lows air flowing throug h the air flow sectio ms 334 and 344 to pass thr ough the chemical impr-egnated body 320.
[0341] Air is also allowed to flow thr ough the space 321c formed be- tween the recessses 335, 336 and 337 aand the lower face of the chemi- cal impregnate:d body 320.
[0342] So cons-tructed and adapted as mentioned above, thee chemical cartridge 303 i s loaded in the main camsing body 301 and ir this form of implementat ion is attached to the upper face of the housi ng 306.
[0343] And, rotating the fan 304 causes air to flow tlarough the chemical impregnated body 320 and chemical to emanate =and diffuse into the enviroramental atmosphere. :
[0344] Also, chemical in a region of ®he chemical impregriated body 320 which is h-eld between each pair eof support and hold sections is allowed to vola-tilize the space 321c an d then to be entrained there in air flowing fromm the vent holes whereby air having chemicall entrained therein is emitt=ed into the atmosphere as the fan 304 is rotated.
[0345] Also, woth the support section s 331, 332 and 333 formed on their upper faces with the recesses 335 , 336 and 337 to form the space 321c and with the hold sections 341, 342 and 343 formed with the vent holes 345, 346 and 347 to make t=he space 321c open ®&o the out- side, it is possilole to use the recesses 335, 336 and 337 to h-ave a used chemical carriem 320 impregnated agair with a chemical.
[0346] For exammple, a used chemical cartridge (with a che mical car- rier depleted of” chemical) 303 is remowed from the main casing body 301 and liquid chemical is poured into the vent holes 345, 346 and 347 to supply and stzore the recesses 335, 336 and 337 therewith.
[0847] Liquid c=hemical stored in the r-ecesses 335, 336 and 337 is al- lowed to impregnate into the chemical carrier 320 over its e ntire body to form an unus ed chemical cartridge impregnated with the echemical.
[0348] Since liquid chemical loaded in the recess 335 is im pregnated into a center r-egion of the chemical carrier 320, liquid chemical loaded in the aranular recess 336 is impregnated into a peri pheral re- gion of the chemical carrier 320 and licguid chemical loaded in the re- cess 337 for cormmunication is impregiated into an interm ediate re- gion of the chemmical carrier 320, the chemical carrier 320 ®s impreg-
nated with chemical quickly over its entir~e body.
[0349] Here, ways in which to supply a liquid chemical may visuaally check an amount of its supply using a calibrated dropping pipette=, a dosage ampule, a metered container or =a container with a metering cup, om a nozzle.
[0350] Also, since in supplying a chemical it is convenient if the t1 me of its supply can visually be checked, it i= desirable to use a chemi cal impregnated body 320 that may be of kraown type with an indicator displaying the time of its depletion.
[0351] While in the form of implementa tion described above the re: ceptac le body member 330 is shown as having three support sections 331, 3 32 and 333 formed in their upper faces 331a, 332a and 333a with r-ecesses 335, 336 and 337 and the receptacle cover member 340 as hav ing three hold sections 341, 342 ancl 343 formed with vent holes 345, 3 46 and 347, not limiting the same= and they may have only= a pair of opposed support and hold sections: formed with a recess and a vent h ole, respectively, or two pairs of opposed support and hold seec- tions feormed with recesses and vent holes,. respectively.
[0352] To wit, there should be at least a pair of opposed support a nd hold sections formed with a recess and a v ent hole, respectively.
[0353] For example, in a modification ass shown in Figs. 32 and 33, the pewipheral support section 332 in the receptacle body member 3 30 may hzave its inner edge bent inwards to form an annular recess 3 36 whose cross section is in the form of a V_ providing a space 321c loe- tween -itself and the lower face of the chemical impregnated body 32€D.
[0354] On the other hand, portions of the peripheral hold section 3 42 in the receptacle cover member 340, e. g. portions where it continu_es to the intermediate hold sections, may b-e bent inwards to form i—e- cesses 348.
[0355] These recesses 348 are formed to provide vent sections 321d betwee n themselves and the raised rim Z332b of the receptacle boedy membe xr 330.
[0356] While in this case the space 3Z21lc is formed beneath tihe chemic al impregnated body 320, it may al-ternatively be formed above or both. above and beneath the chemical im: pregnated body 320.
[0357] Not only is a chemical cartridgge 303 according to thee present inventi on used with a blower type ckaemical diffusing apparatus as describ ed above, but also it can be directly attached to the fan in an air blower and may otherwise be integzrated into the fan. Further, it can be disposed in either an air inlet or outlet side. Yet furth er, it can be attached at the blowout port of an a:ir conditioner.
[0358] The chemical that can be impregnated into a chemical carrier or impmegnated body of the present i mvention may be a in sect pest control agent (insecticide, repellent, gr-owth inhibitor, miticicle, insect control essential oil or the like), arommatic, aromatic deodo rant, de: odorants, fungicide, disinfectant or ve rmin repellent, and e= specially such a «hemical that is volatile at an oxdinary temperature om air flow conditions.
[0359] Such chemicals, if used to kil.l insects, may be a v ariety of volatile insecticides so far known, of which pyrethroid, ca rbamate, organophosphorus chemicals and so on can be listed, further of which pyrethroid chemicals can preferably be used as generally high in safety.
[0360] Further, such specific chemicals as methofluthrin, transflu- thrin, empenthrin, terallethrin and pr-ofluthrin which are h ighly ac- tive ane which in a small amount exh 1bit efficaciousness cam desira- bly be wmsed as they can make the chem# cal carrier thin and small.
[0361] The blank materials of which t-he chemical carrier of the pre- sent in-—vention may be formed includes natural and chemical fibers, nonwov en fabric (of natural, chemical. and carbon fibers), 1—esin net (polyester, polypropylene, polyvinyl chl oride), cloth (woven or knitted), paper y=arn (pulp, linter, synthetic paper). The material may be a formed body such in the form of a shee-t, net, honeycomb, drazn board, or lattice, a body yieldable to keep its sshape when confined, or floccu- late or sponge.
[0362] Of these materials, a sheet-lik_e material of nonwoven fabric that excels in air permeability and chermical retention is prefe rred.
[0363] An explanation is next given ira respect of a fifth for m of im- plementation of the present invention.
[0364] While with reference to Fig. 334 a chemical cartridg-e in an- —60—
I other form of the present invention will, as an example of its use, be described as applied to a blower type chemical diffusirmg apparatus using a chemical c artridge to diffuse a chemical into an atmosphere, this particular use is not a limitation of the invention.
[0365] As shown im Fig. 34, a main casing body 401 is p rovided with an air blower 402 and has a chemical cartridge 403 removably at- tached thereto whe rein a fan 404 of the air blower 402 is rotated by a motor 405 to pass air through the chemical cartridge 403.
[0366] The main c asing body 401 includes a base member 410 and a cover member 411, is formed with a blower mounting sec tion 412 and a battery accepting section 413 and has an air inlet section 414 and an alr discharge section 415.
[0367] The air blower 402 has a fan 404 and a motor 405 mounted in a housing 406 provided in the blower mounting section 412. The housing 406 has am air inlet port 406a communicating ~with the air inlet section 414 and also has an air discharge port (not shown) com- municating with th e air discharge section 415.
[0368] A battery 407 shown as comprising two dry cells. is attached into the battery accepting section 413.
[0369] The cover member 411 is so connected to the main casing body 410 that it can be opened and closed whereby opening the cover mem- ber 411 allows the chemical cartridge 403 and the battemy 407 to be removed and fitted in.
[0370] The chemic al cartridge 403 is adapted to accept- a chemical carrier or impregnated body 420 in the form of a porous o r air perme- able and liquid absorptive sheet impregnated with a ch_emical, and has a retainer or retainer receptacle 421 for retaining t he chemical impregnated body 4-20.
[0371] In other weords, since the chemical impregnated body 420, which is in the form of such a sheet, so liquid-absorptive sand so weak in stiffness that it «<annot sustain itself and if it is held Airectly by a hand, a chemical therein may adhere to the hand, it is laeld along a portion thereof with the retainer receptacle 421 to cause air to pass through other portions thereof.
[0372] The retainer receptacle 421 includes a holder s ection 421a molding the chemical impreagnated body 420 and an aim flow section 4.21b through which air flo ws. The holder section 421a_ has a liquid p- ool recess 421c at its center, namely at the center of th e retainer re c eptacle 421.
[0373] The housing 406 is formed with a recess 406b in which the re- t.ainer receptacle 421 is fitted and firmly seated. Then_ rotating the faan 404 causes air to flow tharough the chemical impregnated body 420 a.nd chemical to emanate and diffuse therewith into the environ: mental atmosphere.
[374] So constructed as mentioned above, the chemical cartridge 403 a fter use, namely with chemmical carrier 420 depleted of chemical, is reemoved from the main casing body 401, and liquid cheamical 1s sup- p lied into the liquid pool recess 421c and pooled there.
[0375] Liquid chemical pooled in the liquid pool recess 421c is al lowed to impregnate the chemical carrier 420 progressiv ely therewith o—ver its entire body to formm an unused chemical carticidge impreg- n ated with the chemical. [O376] Therefore, this is a chemical cartridge that can be repeatedly u sed by being re-supplied with chemical each time it is u=sed up.
[0377] Since the chemical cartridge 403 is seated oppos-ed to the fan 4+Q4 with its center opposed to the center of the fan 404, the center of tke retainer receptacle 421 i s opposed to that of the fan 4-04.
[378] Thus, provided positioned at the center of the restainer recep- tzacle 421, the liquid pool re-cess 421c in the use of the a pparatus lies ir an area where the air flows by rotation of the fan 44 are scarce, amd little impedes them, permitting almost all of them to pass tharough the chemical impresgnated body 420 and thereloy to be con- sumed effectively to diffuse chemical into the atmosphe. re with little lowss of the output of the air blower 402. [O379] To wit, the liquid pool recess 421c as shown in Fug. 34 is posi- ti oned to lie opposed to the center of the fan 404 coupled to the axis of rotation 405a of the motor =405 where the air flows froma the fan 404 resach least around it and ar e substantially in no way im peded by the presence of the liquid pool rescess 421c. [o»380] Also, the chemical ca rtridge 403 can be made thi because the —g2—
chemical carrier or im pregnated body 420 is here thin and. the re- tainer receptacle 321 can be made thin.
[0381] Mention is nex® made of a specific shape of the ret=iner re- ceptacle 421.
[0382] The retainer receptacle 421 as shown in Figs. 34 and 35 com- prises a receptacle body member 430 and a receptacle cover member 440 by and between wh ich the chemical impregnated body 420 is held and retained.
[0383] The receptacle body member 430 has a central suppor section 431, a peripheral supp ort section 432 spaced from and aro und the central support section 430 and a plurality of connecting support sec" tions 433 connecting the peripheral support section 432 to the central support section 431 wherein a space defined with the central support “section 431, the peripheral support section 432 and neighbor ing con- necting support sectioras 433 connected together by the pe ripheral support section 432 is opgpen constituting an air flow section 434.
[0384] The central support section 431 has its support fa ce 43la formed with a recess 435.
[0385] The receptacle cover member 440 has a central hold section 441, a plurality of perip heral hold sections 442 spaced and aro=und the central hold section 4471 and a plurality of connecting hold sections 443 connecting the per ipheral hold section 442 to the cent¥ral hold section 441 wherein a space defined with the central hold sectaon 441, the peripheral hold sectzion 442 and neighboring connecting h old sec- tions 443 connected toggether by the peripheral section 442 1s open constituting an air flow section 444.
[0386] The central hold. section 441 is identical in size to the central support section 431 and. has a supply port 445 opposed to the recess 435, the supply port 44-5 and the recess 435 constituting the liquid pool recess 421c.
[0387] The peripheral hold section 442 is identical in size to the pe- ripheral support section 432.
[0388] The connecting “hold sections 443 are identical in shape and size to the connecting swupport sections 433, and the air flow sections 444 are opposed to the a ir flow sections 434 so that air smoothly flows through tooth the air flow sections 434 and 444.
[0389] The receptacle body member 430 and the receptacle cover member 4440 are detachably attached to-gether.
[0390] Ir the form of implementation illustrated, the peripheral support section 432 has its outer edg e raised from its suppo xt face 432a to Form a raised rim 432b in th.e form of a ring in which the chemical impregnated body 420 is fitteed and then the receptacle cover member 440 is fitted.
[0391] A s an alternative to this attach ment design, the cover member 440 may be formed with such a raised rim which can be fitted o=ver the outer edg=e or rim of the peripheral sugpport section 432 to attach the cover me mber 440 to the receptacle b ody member 430. Yet a lterna- tively, th_e receptacle body and cover members 430 and 440 rmay be provided with a pin and a hole which c¢ an be mated with each o ther to attach th ese members together.
[0392] A 1so, while in this firm of immplementation the conraecting support sand hold sections 433 and 443 are each shown comprasing a plurality of subsections extending radiaally, not only may such subsec- tions if a dopted be in the form of a latttice but also each section 433, 443 may, for example, comprise a porous plate or the like.
[0393] Seo constructed and arranged ass mentioned above, the retainer receptacle 421 acts to hold and supporft the chemical cartridge 420 by supportimg and holding a central regiom thereof with and between the central support and hold sections 431 and 441, a peripheral region thereof wsith and between the periphe=ral support and hold sections 432 and 442 and an intermediate regiom thereof with and between the connectin:g support and hold sections 433 and 443.
[0394] TrChis allows air flowing through the air flow sections 4-34 and 444 to pa ss through the chemical impre gnated body 420.
[0395] Thus, a used chemical cartridegge (with a chemical carr ier de- pleted of chemical) 403 is removed fron the main casing body 4 01 and liquid chemical is poured into the supp ly port 445 to supply and store the recess 435, or the recess 435 and th.e supply port 445 therew=ith.
[0396] L=iquid chemical stored in the recess 435 is allowed to im- pregnate into the chemical carrier 320 over its entire body to form an unused chemical cartridge impregnated with the chemical.
[0397] The depth of the liquid pool rescess 421c can be determined depending on the amount of chemical t o be supplied and has no par’ ticular limitation. If the lower face of tThe sheet and the upper face of the reecess 435 abut each other, the deppth may then be such that the liquid chemical supplied stays by its s urface tension with t he sheet body. If the depth is excessive, then so me liquid may be left without contac ting the sheet.
[0398] Mention is next made of a firs® modification of the chemical cartriclge mentioned above.
[0399] As shown in Figs. 36 and 37, tlhe central support section 431 of the receptacle body member 430 is made larger in size than the centra 1 hold section 441 of the receptacle cover member 440 with re- cess 4335 larger in size than the central Ihold section 441.
[0400] The central hold section of thee cover member 440 is made thicke r than the connecting section 4413 so it protrudes do-wnwards beyond each connecting section 443 to p ress the chemical impregnated body 4-20 into the recess 435 therewith.
[0401] This assists the chemical stored in the recess 435 to impreg- nate imto the body the sheet.
[0402] If the sheet is positioned to lie close to or in contact with the base oef the recess 435 as shown in Figg. 37, the depth of tlhe recess 421c i s determined depending on the ammount of chemical tos be sup- plied =and need not be much since the «chemical as soon as 1 tis sup- plied will begin to permeate around.
[0403] The preceding form of implememtation and its first rmodifica- tion mentioned above are particularly advantageous if the chemical impresznated body 420 is small. If it is “large, it is desirable to form a liquid pool recess in the peripheral section as well so that chemical may b e supplied into both the central aand peripheral section s to per- meate both from central towards perip heral and from peripheral to: wards central.
[0404] This is effective to have chemi cal permeate quickly into the entire body of a sheet and thus advanta geous in the man manufacture of sucEa products.
[0405] For exarmple, in a second modifica tion as shown in Figs. 338 and 39, in the rexceptacle body member 431 the central support sectiom 431 is formed w=ith the recess 435 and thes peripheral section 432 1s formed with a pesripheral recess 436 that is e. g., annular.
[0406] The cen-tral hold section 441 in -the cover member 440 is formed with thes supply port 445. Each cornnecting section 443 1s ex tend outwards teo project from each periphe ral hold section 442, form. - ing an extensiorm 443a in contact with the r aised edge 432b while pro=- viding a gap between the peripheral hold ssection 442 and the raised edge 432b to con stitute a peripheral supply port 446.
[0407] A periph eral recess 436 thus formed is made to act as a liquid pool recess 421c in the peripheral section.
[0408] In this s econd modification, the per ipheral hold section 442 1 s made thicker th an the central hold section. 441 to press a peripheral edge of the chemical impregnated body 420 into the peripheral reces s 436 to assist the chemical to permeate into the chemical impregnate«d body 420.
[0409] Also, in a third modification as sho wn in Figs. 40 and 41, the peripheral suppeort section 432 of the receptacle body member 430 1s bent downwards so that a peripheral recess 436 is formed by the ben t peripheral support section 432 and the raised edge 432b.
[0410] The conrecting sections 443 of the ecover member 440 are als-o bent downwardss so the peripheral hold se ction 442 conforms to the bent peripheral support section 432.
[0411] This pre sses a peripheral edge of the chemical impregnated body 420 against the peripheral support sec tion 432.
[0412] Portions of the peripheral hold sectzion 442 of the cover mem - ber 440, e. g., where it connects to the co-mnecting sections 443, are deformed to formn dents 442a there, thereby forming openings betweem these dents and the raised edge 432b, respectively, to constitute pe-- ripheral supply Jports 446.
[0413] Also, in a fourth modification as shown in Figs. 42 and 43, th e central hold section 441 of the cover member 440 is formed with = downward facings recess 445a which is in turn formed on its top face with a plurality of small supply holes 445b whereby the downward facing recess 445a and the supply holes 445b constitute a ssupply port 445 and the supply port 445 andl the recess 435 constitu~te a liquid pool recess 421c.
[0414] The peripheral hold sectio n 442 of the cover membe=1 440 com" prises an inner vertical subsectiom 448 and a top flat subssection 449 which define a downward facing recess 446a wherein the top flat sub- section is formed with peripheral supply holes 446b whic-h together with the downward facing recess 446a constitute a peripheral supply port 446 and the latter and the peripheral recess 436 const itute a liq- uid pool recess 421c in the peripheral section.
[0415] Also, it is possible to enhance the surface tensiom of liquid chemical with the sheet. To this e nd, the inner base of eacl of the re- cesses may be processed by embossing or the like to impart surface irregularities thereto, to create srmall spaces in the form o f a lattice, or a plurality of raised edges may be provided to form groov es.
[0416] As mentioned before, ways in which to supply a liq uid chemi- cal into a liquid pool recess 421c rmay visually check an am_ount of its supply using a calibrated dropping pipette, a dosage amp ule, a me- tered container or a container with a metering cup, or a noz zle.
[0417] Also, since in supplying a <hemical it is convenient if the time of its supply can visually be checked, it is desirable to use a chemical impregnated body 420 that may be of known type with ar indicator displaying the time of its depletion.
[0418] Further, not only is a chermical cartridge 403 according to the present invention used with a blower type chemical diffusimng appara: tus as described above, but also it can be directly attached to the fan in an air blower and may otherwise be integrated into the fan. Fur- ther, it can be disposed in either an air inlet or outlet sid-e. Yet fur- ther, it can be attached at the blowout port of an air conditieoner.
[0419] The chemical that can be impregnated into a chemi cal carrier or impregnated body 420 of the present invention may be a fnsect pest control agent (insecticide, repellemt, growth inhibitor, mitic-ide, insect control essential oil or the like), aromatic, aromatic deod orant, de- odorant, fungicide, disinfectant or vermin repellent, and especially such a chemical that is volatile at an ordinary temperature or air flow — eT —
conditions-.
[0420] Swu.ch chemicals, if used to kill insects, may be a variety of volatile irsecticides so far known, of which pyrethroid, carkoamate, organophossphorus chemicals and so on can be listed, further o=f which pyrethroid chemicals can preferably b e used as generally righ n safety.
[0421] Further, such specific chemical s as methofluthrin, tr-ansflu- thrin, empenthrin, terallethrin and pro fluthrin which are highly ac tive and vvhich in a small amount exhiloit efficaciousness can desira- bly be use d as they can make the chemic-al carrier thin and small.
[0422] Thae blank materials of which th_e chemical carrier of t he pre- sent invertion may be formed include natural and chemical fibers, nonwoven fabric (of natural, chemical and carbon fibers), ressin net (polyester , polypropylene, polyvinyl chlo ride), cloth (woven or k=nitted), paper yar n (pulp, linter, synthetic paper). The material ma y be a formed bo dy in the form of a sheet, ne t, honeycomb, drain board or lattice, a body yieldable to keep its shap-e when confined, or flo cculate or sponge.
[0423] Of these materials, a sheet-like material of nonwoven: fabric that excelss in air permeability and chem ical retention is preferred.
[0424] Am explanation is next given in respect of a sixth form_ of im- plementat ion of the present invention.
[0425] WHEaile with reference to Fig. 44 a chemical cartridge in an- other form of the present invention will , as an example of its use, be described as applied to a blower type chemical diffusing apparatus using a ch emical cartridge to diffuse a chemical into an atmosp bere, it will be urmderstood that the present irmvention when applied is not limited to this particular use.
[0426] As shown in Fig. 44, a main caszing body 501 is provided with an air blower 502 and has a chemical cartridge 503 remova bly at: tached thereto wherein a fan 504 of the air blower 502 is rotatezd by a motor 505 to pass air through the chemical cartridge 503.
[0427] Th_e main casing body 501 inclucdes a base member 510 and a cover member 511, is formed with a blower mounting section 5 12 and a battery -accepting section 513 and has an air inlet section 5 14 and
& an a ir discharge section 515. [042 8] The air blower 502 has a fan 504 and a motor 505 mounted In a housing 506 provided in the blower mounting section 5-12. The houssing 506 has an air inlet port 506a communicating with the air inlet: section 514 and also has an air discharge port (not shov=n) com- mun_icating with the air discharge sectiora 515. [042 9] A battery 507 shown as comprising two dry cells is =attached into the battery accepting section 513. [043 0] The cover member 511 is so connected to the main cas ing body 510 that it can be opened and closed whereby opening the cov-er mem- ber 511 allows the chemical cartridge 5€3 and the battery 5 07 to be remaoved and fitted in. [043-1] The chemical cartridge 503 is adapted to accept a ochemical impmegnated body 520 in the form of a skeet and has a retain._er or re- tain er receptacle 530 for retaining the chemical impregnatzed body 520. : [0432] In other words, since the chemical impregnated body 520, which is in the form of such a sheet, so 1 iquid-absorptive and so weak ’ in stiffness that it cannot sustain itself and if it is held direactly by a haned, a chemical therein may adhere to- the hand, it is held_ along a port-ion thereof with the retainer recept acle 530 to cause air~ to pass throsugh other portions thereof. [04% 3] This permits the chemical cartri dge 520 to be made -thin and easy” to handle.
[0434] The chemical impregnated body 520 comprises a carriesr 521 in the form of a sheet impregnated with and retaining therein a - chemical in a given amount.
[0435] The sheet-like carrier 521 of the chemical impregnated body 520 has a high liquid retention region 522 that can at a timsze be im- pregznated with and capture a large am ount of chemical, which pro- gresssively permeates into the carrier 521 over its entire body.
[0436] So constructed and adapted as mentioned above, a chemical cart=ridge 503 when used out (when chermical contained in th e carrier 521 of the chemical impregnated body 520 is depleted or co mpletely diffwased into the environmental atmosphere and the carrier 521 has no such chemic al contained therein) allows re-s upply by dropping and thereby supplyzing a large amount of chemical i nto the high liquid re- tention region 522 to allow the chemical to p-rogressively permeate into the carriem 521 over its entire body until the carrier 521 is fully charged with t he chemical, thereby reproducimg an unused chemical cartridge.
[0437] Therefosre, this is a chemical cartridge —that can be repeatedly used by being re supplied with chemical each timme it is used up.
[0438] Also, si nce in the stage of manufacture as well, the carrier 521 of a chemical immpregnated body 520 can be supplied in its high liquid retention regio=n 522 with a large amount of chemical to allow it to permeate into the carrier 521 progressively over its entire body, it 1s possible to impregnate the carrier 521 uniform ly over its entire body with chemical.
[0439] Mentiom is next made specifically of a presently preferred but not exclusive e xample of the chemical cartridge 503 with reference to
Figs. 45 and 465.
[0440] The cawmrier 521 of this chemical impre=gnated body 520 is in the form of a sheet whose central part is thicker than elsewhere thereof, constitzuting the high liquid retention resgion 522.
[0441] The high liquid retention region 522 is formed in its top with a recess 522a t-o assist chemical when supplied to be absorbed into its inside easily.
[0442] Even if” the liquid absorptivity (the mag nitude of an amount of liquid that can be absorbed in unit area) of the carrier 521 is uniform ‘over its entire area, its central area made th:in can absorb a large amount of chemical and can constitute the higzh liquid retention re- gion 522.
[0443] Prefera_bly, however, the carrier 421 ca n be made more liquid absorptive in i-ts central part than in the other parts, permitting this part (the high liquid retention region 522) to We impregnated with a maximum amo-unt of chemical.
[0444] However, if the high liquid retention re-gion 522 of the carrier 521 is made h_igher in liquid absorptiveness tthan its other regions, this region can. be made equal in thickness to time other regions.
[0445] Thus, the high liquid retentiom region 522 of a carri er 521 can in effect be a region where the amount of liquid that can be absorbed per unit volume is larger than elsewhere thereof.
[0446] Also, the high liquid retention region 522 may have =any shape, i. e., not only round as mentioned buat also rectangular, se micircular or raising, depending on its blank material used.
[0447] The retainer receptacle 530 comprises a receptcacle body member 540 and a hold member 550 by and between which the chemical impregnated body 520 is held and retained.
[0448] The receptacle body member 540 has a central suppeort section 541, a peripheral support section 542 and a plurality of sconnecting support sections 543 connecting the peripheral support sect-ion 542 to the central support section 541 wherein a space defined witch the cen- tral support section 541, the perip heral support sectiora 542 and neighboring connecting support sect ions 543 connected together by the peripheral support section 542 is open constituting a n air flow section 544.
[0449] The peripheral support section 542 has its outer e dge raised from its upper face to form a raised eclge 545 in the form of =a ring.
[0450] The chemical impregnated b ody 520 is placed on and sup- ported by the upper faces 541a, 542a and 543a of the centr—al and pe- ripheral and connecting support sections 541, 542 and 543.
[0451] The hold member 550 is in the form of a ring that ca_n be fitted with the ring-shaped raised edge 545 to hold a peripheral part of the chemical impregnated body 520 by amd between the hold rmember 50 and the peripheral support section 54 2.
[0452] The chemical cartridge 503 as shown in Fig. 44 i=s mounted fitting with its mounting section 5065 of the housing 506 arnd opposed to the fan 504 of the air blower 502 so that the central pamrt 504a of the fan 404 little in air flow (namely, where the axis of rot ation 505a of the motor 505 is coupled thereto) iss opposed to the centra_lpart (the high liquid retention region 522) of the carrier 521 of thes chemical impregnated body 520.
[0453] Thus, through the high liquid retention region 522 there will air flow much less than elsewhere around it to allow a_ir to flow smoothly through the chemical impregnated body 520 without being impeded by the high liquid retention region 522 d espite its thickness.
[0454] Bei ng placed on the upper face 541a of tlhe central supporting section 541 of the retainer receptacle 540, the high liquid retention region 522 supplied with a large amount of che mical when it 1s re- filled to ad d to its weight is prevented from comirmg down.
[0455] Als o, being identical to or larger than the high liquid reten- tion region 522 in size, the central support sectiom 541 prevents liquid chemical frrom leaking down from the lower face «of the high liquid re- tention reggion 522 when it is supplied with a la rge amount of liquid chemical.
[0456] The central support section 541 may be i n the form of a shal- low and demted dish
[0457] A rmention is next made of modifications of this form of im- plementati on.
[0458] The central support section 541 of the rec eptacle body member 540 may be smaller in size than the high liquid retention region 522.
Further, the connecting sections 643 may only be six but also four, three or th e like in number.
[0459] In a first modification as shown in Figs. 47A and 47B, the hold membeer 550 may have a central ring 551, aa peripheral ring 552 and a pluwality of stays 553 connecting the cemtral and peripheral rings 551 and 552 to form openings 554 and may" so be made that the central rin g 551 fits with the high liquid retention region 522 and the peripheral ring 552 fits with the ring-shaped ra ised edge 545 of the receptacle body member 540.
[0460] This allows the central ring 551 to prowide an indication of chemical d ropped and supplied.
[0461] In this case, the central support section 541 of the receptacle body member 540 may be in the form of a ring.
[0462] Also, in this case, the central ring 551 of the hold member 550 may abut on the upper face of the high liquid re tention region 522 to hold it with the central support section 541.
[0463] Also, the central ring 551 may be large in height than the high liquid retention region 522 to prevent liquid chemical supplied from leaking.
[0464] In a second mod ification as shown in Figs. 484 and 48B, the chemical impregnated body 520 may have its high liqui.d retention re- gion 522 located closer to the periphery of the carrier 5221.
[0465] For example, the carrier 521 may have a plurality of high lig uid retention regions 522 positioned circumferentiall® spaced apart from each other along a peripheral area thereof. ) [0466] In a third and a fourth modification as shown mn Figs. 49 and 50, the high liquid reterition region 522 of the chemicaal impregnated body 520 is in the form of a narrow band extending =nd continuous diametrically. The high liquid retention region 522 heere is supplied with liquid chemical froom the central region, such as t he central ring 551, of the hold member 550 in the arrangement shown. in Fig. 49 and from the peripheral region, such as openings 554 formeed between the dents 552a of the perip heral ring 552 deformed of thee hold member 550 and the ring-shape d raised edge 545 of the peripheral support section 542 of the receptacle body member 540 in th e arrangement shown in Fig. 50. In further modifications not shown. a plurality of such band-shaped high liquid retention regions 522 mmay be formed and arranged in the forrm of a lattice, or one or more o#f such high lig- uid retention regions 52= may be positioned suitably as desired.
[0467] The high liquid retention region 522 of the ch emical impreg- nated body 520 may be formed separately from the c arrier 521 and may be laid above and/ow below the carrier 521.
[0468] For example, in a fifth modification as shown ina Fig. 51, a pair of carriers 521 are used to hold a high liquid retention region 522 be- tween them.
[0469] Also, in a further modification not shown, the high liquid re- tention region as a sepa rate body is fitted into the cen®tral ring 551 of the hold member 550 an d thereby mounted while the hold member 550 is attached the receptacle body member 40 so as to brirmg the high lig- uid retention region 522 into contact with the carrier 5221.
[0470] Alternatively, tlhe carrier 521 may be laid on -the high liquid retention region 522 mounted as a separate body on the central sup- port section 541 of the receptacle body member 540.
[0471] Mention is next made of how the high liquid restention region 522 described above may specifically be implemented.
[0472] The high liquid retention region 522 as a sepoarate body 1s formed of a same material or a material dissimilar to that of which the carrier 521 is formed, and is integrated with, or bonded to, seamed with, placed on or welded to the carrier 521.
[0473] Alternatively, a blank material is blown by spe cial machining on a portion of the carrier 521 to make “metsuke” lar ge to build up there a high liquid retention region 522.
[0474] The blank materials of which the carrier 521 osf the chemical impregnated body 520 or the high liquid retention re=gion 522 as a separate body in the present invention may be formed i nclude natural and chemical fibers, nonwoven fabric (of natural, chemi cal and carbon fibers), resin net (polyester, polypropylene, polyvinyl chloride), cloth (woven or knitted), paper warn (pulp, linter, synthetic paper). The material may be a formed b ody such in the form of a s heet, net, hon- eycomb, drain board, lattice or fold, a body yieldable to keep its shape when confined, or flocculate or sponge, and further foamed beads, foamed urethane, and wooden or bamboo charcoal.
[0475] Of these materials, a sheet-like material of nonwoven fabric that excels in air permeability and chemical retention is preferred.
[0476] In the present inve ntion, ways in which to s upply a liquid chemical into a high liquid retention region 522 may visually check an amount of its supply using a calibrated dropping pip ette, a dosage ampule, a metered containex or a container with a met ering cup, or a nozzle.
[0477] Also, since in supplying a chemical it is conveni ent if the time of its re-supply can visually be checked, it is desir—able to use a chemical impregnated body 420 that may be of knowra type with an indicator displaying the time of its depletion.
[0478] The chemical that can be impregnated into the carrier 521 of a chemical impregnated body 521 for use in the present invention may be an insect pest control agent (insecticide, repellent, growth inhibi- tor, miticide, insect control essential oil or the like), aromatic, aro- matic deodorant, deodorant, fungicide, disinfectant or vermin repel m4 lent, and especially such a chemical that is volatile at an oerdinary temperature or air flow comditions.
[0479] Such chemicals, if used to kill insects, may be a va riety of volatile insecticides so far known, of which pyrethroid, carbamate, organophosphorus chemicals and so on can be listed, further of which pyrethroid chemicals can preferably be used as generally high in safety.
[0480] Further, such spe cific chemicals as methofluthrin, transflu- thrin, empenthrin, teralle thrin and profluthrin which are highly ac- tive and which in a small amount exhibit efficaciousness can desira- bly be used as they can make the chemical carrier thin and sm all.
[0481] Further, not only is a chemical cartridge 503 accordin g to the present invention used wi th a blower type chemical diffusing appara- tus as described above, buat also it can be directly attached to the fan in an air blower and may otherwise be integrated into the fan. Fur- ther, it can be disposed in either an air inlet or outlet side. "Yet fur- ther, it can be attached at the blowout port of an air conditioner. ] [0482] An explanation is mext given of a seventh form of impl ementa- tion of the present inventi on.
[0483] While with refere nce to Fig. 52 a chemical cartridge in an- other form of the present invention will, as an example of its use, be described as applied to a. blower type chemical diffusing apsparatus using a chemical cartridges to diffuse a chemical into an atmosphere, it will be understood that the present invention when applied is not limited to this particular use.
[0484] As shown in Fig. 52, a main casing body 601 is provided with an air blower 602 and h as a chemical cartridge 603 remov ably at- tached thereto wherein a fan 604 of the air blower 602 is rota ted by a motor 605 to pass air thro ugh the chemical cartridge 603.
[0485] The main casing body 601 includes a base member 61.0 and a cover member 611, is formed with a blower mounting section 612 and a battery accepting section 613 and has an air inlet section 614 and an air discharge section61 5.
[0486] The air blower 602 has a fan 604 and a motor 605 morunted in a housing 606 provided in the blower mounting section 6 12. The housing 606 has an air inlet port 606a co mmunicating with the air inlet section 614 znd also has an air discharge port (not shown) <com- municating with t he air discharge section 6 15.
[0487] A battery 607 shown as comprising two dry cells 1s atta ched into the battery aeccepting section 613.
[0488] The cover member 611 is so connect-ed to the main casing body 610 that it can be opened and closed where by opening the cover rem" ber 611 allows th.e chemical cartridge 603 and the battery 607 fo be removed and fitte d in.
[0489] The chem ical cartridge 603 includes a chemical retainer or chemical impregmated body 620 and a fixture 630, although. the chemical cartridge 603 is not limited to a combination of su ch a chemical impregriated body 620 and a fixture but may comprise a chemical impregrmated body 620 and a reeceptacle that will be de- scribed later or mmay comprise only a chemical impregnated body 620.
[0490] The chem ical impregnated body 620 as shown in Figs. 52 to 56 is made of a por ous or air permeable and liquid absorptive pleated sheet material 6221 that is flat and impregnated with a chemical, as shown. A number of pleats of the chemical impregnated body 62 O are formed by alternating mountain fold and walley fold of the shee® ma- terial at certain wwvidths.
[0491] The chem ical impregnated body 62 O made of such a sheet ma- terial 621 which is thus large in surface amwea per unit volume amd ca- pable of retaining liquid chemical can reta:in a large amount of Liquid chemical per unit volume and moreover c an be enough if it is made small in size.
[0492] For exam. ple, it is possible to provide a thin chemical im preg- nated body 620 ceontaining a large amount of liquid chemical.
[0493] This sheet 621 is prevented from losing its pleated shape by jointing, e. g. thermally fusing its peripheral edge 622, across wwhich pleats are made parallel, to maintain a pitch of pleats. To it , if a pleated sheet is left with its pleats as they are, under an external force it tends to lose its shape and become unable to mainta in its original pitch of plates.
[0494] So processsed, the sheet material 621 allows air to pass uni- ne —
formly over its entire area and in turn chemical to emanate f rom the chemical impregnated body 620 uniformly over its entire area.
[0495] This thus permits a volume of chemical retained in the chemical impregnated bod=y to be consumed substantially uriformly over its entire area, thereby rendering the utilization of a chemical for this purse effective and efficient.
[0496] In the form of implementation illustrated, the chem ical 1m- pregnated body 620 is round in its planar shape with its pe ripheral edge 622 in the form of a ci rcular ring.
[0497] This does not excl ude the possibility that the chem ical i1m- pregnated body 620 may be square or rectangular in its plana.r shape; then two opposed edges of i-t may be fused.
[0498] The fixture 630 acts to hold the peripheral edge of thee chemi- cal impregnated body 620 to maintain its shape and prevent it from deforming. It also serves ®o enable the chemical cartridge 6 03 to be held by fingers while presventing chemical from contamina ting the hand. Air is, of course, all owed to pass through the chemical impreg- nated body 620 except in its limited area where it is held by~ the fix- ture 630.
[0499] Thus, the fixture 6 30 has a hold section that holds th e chemi- cal impregnated body 620 and an air passage section through which air flows.
[0500] For example, the faxture 630 comprises a support mermber 631 and a hold member 632, and the support member 631 commprises a raised fitting ring 633 and, as a support element, a support ring 634 projecting inwards from a mn inner face 633a of the raised fitating ring 633 below 1t.
[0501] The hold section 6 32 is here in the form of a ring that can be fitted with a ring-shaped r-aised edge 633 of the support memloer 631.
[0502] Then, the chemical impregnated body 620 is loade d in the support member 631 witch its peripheral edge 622 fitted —with the raised fitting ring 633 and placed on the support ring 634, amd there- after the hold member 6332 is fitted into the raised fitting ring 633 with itself pressed on th e peripheral edge of the chemical impreg- nated body 620 to hold tthe same between the hold member 632 and the support ri ng 634 in the raised fitting ring 633 of the suppeort member 631.
[0503] Thus, the ring-shaped support mermber 631 and the haold member 632 tosgether constitute the aboveme ntioned hold section &and the space in tlhe hold section constitutes the abovementioned air [D2as- sage section.
[0504] In this form of implementation, as slmown in Fig. 56 when the processed shee t material 621 is held by the fi xture 630, it will be s een that its fused peripheral edge 622 is held lyirag at a position vertically midway of the height of the fixture 630 with its upper and lower con- tour lines 621a and 621b projecting upwards- and downwards, respec" tively, to en eq ual extent from that vertically midway position.
[0505] Dependling on the relative thicknesse s of the support and Inold rings 634 and 632 that can be chosen, however, it is also possible: to hold the fused peripheral edge 622 of the pl eated sheet material 621 by the fixture 620 and as in a first modification shown in Fig. 577 to position the sheet material 621 in the fixtur e 630 such that its lo wer contour line 6 21b is relatively flat and its upper contour line 6 21a projects relatiwely largely upwards.
[0506] In any way, it is possible to make tle lower face 620a of the chemical impregnated body 620 substantia lly flush and preferably precisely flush with the lower face 630a of the fixture 630, ther~eby improving the placeablility of the chemical cartridge 603 on the ap- paratus casing body 601. Also, since the support and hold rings 634 and 632 can be thin, it is possible make the fixture 630 small in th_ick- ness and size.
[0507] For ex ample, it will be seen in the arrangement shown in Fig. 52 in which t he chemical cartridge 603 must be placed on a sh oul dered top face 606b of the housing 606 that it is necessary to mmake the lower face 620a of the chemical cartridges 620 flush with the loswer surface 630a of the fixture 630 in order toe make the chemical car: tridge 630 eassily placeable on the housing 6 06. Otherwise, the he ight
H2 of the fixture 630 for the chemical cartridge 603 shown in Figs. 56 tends to becorme larger than the height H1 of the chemical cartradge 603 shown in Fig. 57 by a thickness (height) of the support ring 63 4. — 7g
[0508] Being not only be :air permeable but also liquid absorp tive, the pleated sheet material 62 1 of the chemical impregnated body 620 af- ter depletion of its chemical, namely once the chemical cartridge 1s used out by the fact that the amount of chemical I contains kas been altogether diffused into the environmental atmosphere, can again be supplied and impregnated with chemical over its entire area to pro: vide a chemical impregnated body.
[0509] Hence, a chemical cartridge is provided, which each t ime it 1s depleted can be reused repetitively upon refilling.
[0510] Mention is next m ade of a preferred chemical cartridge that 1s suitable for refilling after depletion, reference being made to Figs. 58 and 59.
[0511] The support elememt 634, illustrated above as the support ring, in the fixture 630 now comprises an outer and an inner peripheral ring 634a and 634b and connecting bars 634c that connect them to- gether.
[0512] Likewise, the hold member 632 of the fixture now comprises an outer and an inner rimg 632a and 632b and connecting bears 632c that connect them together.
[0513] With the cartridge so constructed, the chemical imp regnated body 620 can be supplied with chemical into a region enclosed by the inner ring 632b and refilled easily.
[0514] With the fixture ®630 shown in Figs. 58 and 59, the chemical impregnated body 620 ha ving its upper and lower faces supported by and between the inner rings 632b and 634b and the connecting bars 632c and 634c is prevent.ed from its coming down. In this c ase, only one of the support and hold members 631 and 632 may have such an inner ring and connecting bars.
[0515] The inner rings a.re arbitrary in size, shape and nurmber and can be determined according to the size of the chemical impregnated body 620, the material u sed for the pleated sheet and the a mount of impregnation of chemical .
[0516] Providing an inner ring and connecting bars only for the sup- port member 631 to forma recesses on its upper face allows refilling liquid chemical to stay an these recesses and to be prevemxted from leaking and coming down.
[0517] Although not shown, an indication of refilling a chemical by a color or mark may be provided on a surface of the picocessed sheet material 621 in the chemical cartridge shown in Fig. 54.
[0518] Mention is ne xt made of further modifications.
[0519] As shown in Fig. 60, for the chemical impregnatzed body 620 a pleated sheet material 621 with its peripheral edge 622 that remains unprocessed (unfused) may also be used.
[0520] Then, the fixture 630 in holding the pleated sheet material 621 acts to squeeze its unprocessed peripheral edge 622, thereby holding the same firm to prevent the pleats from getting out of shape.
[0521] It may then be further desirable that the hold rmember 632 be : threadedly engaged with the raised ring 633 of the suapport member 630 to hold the peripheral edge 622 of the pleated sheet material 621..
[0522] A chemical cartridge may simply be a chemiceal impregnated body 620 with its peripheral edge 622 processed as shown in Fig. 53.
[0523] Incorporating a chemical impregnated body 62® into a reccp- tacle 640 having an air passage region may provide aa chemical car: tridge 603.
[0524] For example, in a second modification as show=n in Fig. 61 a receptacle 640 in the form of a ring has its inner round area providing the air passage region and is formed with an inwardly facing annular recess 641 in its outer ring section. The processed peripheral edge 622 of the chemical impxegnated body 620 is fitted into this annular re- cess 641 to incorporate the chemical impregnated body~ 620 in the re- ceptacle 640.
[0525] In a third modification as shown in Fig. 62, t_he unprocessed peripheral edge 622 of the chemical impregnated bod_y 620 is fitted into this annular recess 641 to incorporate the chemic al impregnated body 620 in the receptacle 640.
[0526] So constructed, the receptacle 640 can be h eld by a hand without causing the hand to be contaminated by chem3cal and is easy to handle.
[0527] While in the various examples of implementa tion mentioned above the chemical impregnated body 620 is shown to be round with the fixture 630 and the receptacle 640 being ring-shaped, the c hemi" cal impregnated body 620 may al=o be rectangular, triangul ar or semicircular with the fixture 630 a nd the receptacle 640 beings then likewise rectangular, triangular or s emicircular.
[0528] Thus, the fixture 630 will be enough if it is configured as be- ing capable of holding and pressing the peripheral edge of a chemical impregnated body 620 and having ar air passage region. Likewise, the receptacle 640 will be enough if it ds configured as accommodating a chemical impregnated body 620 and having an air passage regloru.
[0529] While in the various examples of implementation mentioned above the chemical impregnated body 620 is shown to be plamar to make the chemical cartridge thin, t™he chemical impregnated body 620 may be in the form of a cylinder an d the receptacle 640 may be c¢ylin- drical having an annular hollow in which to receive the chemic al im- pregnated body 620 to provide a che mical cartridge.
[0530] For example, in a forth modification as shown in Figs. 63 and 64, an inner and an outer cylinder 642 and 643 and a pair of emmd face plates 644 and 645 constitute a receptacle 640 having an annular hol- low 646 and an axial hollow 647.
[0531] The inner and outer cylinders 642 and 643 are formed with vents 642a and 643a and one end f ace plate 644 has an airflow open- ing 644a.
[0532] The chemical impregnated Tbody 620 here comprises a pleated sheet material 621 that is air perrmeable and liquid absorptive. This pleated sheet material 621 has its peak to valley height substa ntially equal to a radial with of the annula_r hollow 646 that 1s a difference in radius between the outer and inner cylinders 643 and 642 so it can be fitted in the latter. The pleated sheet material 621 is fitted so its pleat contours conform to opposed walls of the annular hollow 646, and then is impregnated with a liguaid chemical.
[0533] The receptacle 640 thus loa_ded in its annular hollow 646 with the chemical impregnated body 620 provides a chemical cartridge 620.
[0534] The chemical cartridge 620 is removably loaded into the ap- paratus casing body 601.
[0535] For example, in the cartridge 603 the one end face plate 644 is — 8 1-
formed with =n outwardly projecting key element 648 where it define s the air passa ge opening 644a while in tlne apparatus casing body 60°71 is formed with an inward facing key recess 649 where it defines the air inlet operning 614 such that when the key element 649 engages th e key hole 649 the chemical cartridge 603 and the apparatus casin g body 601 are brought firm together whaile bringing the air passage opening 644am and the air inlet opening 614 into communication wit h each other.
[0536] And, with the fan 604 of the air blower 602 driven by the mo- tor 605, air is allowed to flow through the vents 643a of the outer cylinder 643, the annual hollow 646, the vents 642a of the inner cy: inder 642, th_e axial hollow 647, the air goassage opening 644a, the arr inlet section 614 and the air discharge sesction 615, thereby entrainin g chemical fromm the chemical impregnate d body 620 therein for diffua- sion into the environmental atmosphere.
[0537] So constructed, adapted and arr—anged as mentioned above, a chemical impregnated body 620 as in t he preceding forms of imple: mentation can retain an increased amo unt of chemical per unit vo I ume and can yet be made small in size.
[0538] Accowding to this form of impl ementation, with a chemical impregnated body 620 that can retain a mn increased amount of chem i- cal and can be reduced in diameter, a chemical cartridge 603 can bbe made small -in diameter, yet having an increased chemical absorptiw: ity.
[0539] Also, with a receptacle 640 macle easy to handle and sealed, not only cam it be handled easily, but also it does protect the user’s hand from c ontamination with a chemi cal carried by a chemical 1m- pregnated body 620.
[0540] Further, although not shown partition plates may be provided in the annular hollow 646 of the recept acle 640 to prevent the pleats of the pleated sheet material 621 from getting out of shape. Yet fu x ther, the iriner cylinder 642 may ha-ve a plurality of projectioxas circumferenstially spaced apart such tknat adjacent such projectioms hold the peak of each of the pleats to prrevent the pleated sheet mat e- rial 621 froma getting out of shape.
[0541] While a chemical cartridge according to the present inverition is shown above as mounted im the apparatus casing body 601 of a blower type chemical diffusing apparatus so that when blown by an air blower 602 it can emit chiemical into the environmental atmos" phere, it should be understood that the chemical cartridge in this as- pect of the invention is not limited to such a particular use th ereof but can simply be used with a suitable mounting means for place ment in a living room or the like so that it can spontaneously emit chexmical into the atmosphere.
[0542] In this case, the chemical cartridge may be made in the form of a fan, lantern, accordion or curtain.
[0543] The sheet for use to fo rm a pleated sheet material 621 im the present invention is preferably” made of a woven or nonwoven fab ric to meet the requirements of its a ir permeability and liquid absorpt ivity.
It is further desirable that th e material be resistant to chemical de- pending on particular types of chemical used. For example, the raw materials applicable include pulse, cotton, wool, flax and silk as natural fiber, polypropylene, polyethylene, polyamide, polyeth ylene terephthalate, polybutylene terephthalate, polysulfone, r ayon, methacrylate resin and glass fiber as synthetic fiber.
[0544] The pleated sheet material 621 should have as a sheet a thickness preferably ranging between 0.02 mm and 1.0 mm to ke ep its liquid absorptivity and retenti on.
[0545] Also, to facilitate che mical emission (air transmission), the sheet should preferably have a density of 0.05 to 1.0 g/cm3.
[0546] While the fold width of the pleated sheet material 621 c annot be determined outright as it also relates to its fold-up width, <where the object is to make the chemical cartridge smaller and espe cially thinner it cannot be desirable to increase the fold width since this tends to increase the thickne ss of chemical; it should thus be desir: able to determine it dependirig on the area of the chemical impreg- nated body 620. Thus, the fold with should typically range betwreen 2 mm and 30 mm.
[0547] In the case of a cylimadrical chemical cartridge as shown in
Figs. 63 and 64, however, the pleated sheet material 621 may ave a fold width in excess of 30 mm.
[0548] As to the peak to peak distance of pleats of the pleated shee t material 621 there appears to be no particular limitation impose d thereon. However, the wider the distance, the less the amount of chemical can be contained, and if the pleats are densified, an increas e in the amount of chemical abs orbed also impedes air flow and chemm- cal emission. Thus, the distance should typically be mot more than 1 0 mm and not less than 1 mm (where the pleats when visually seen are barely contacting each other).
[0549] Not only can the pleats be even in height (where the fol d width is equal to the fold-up width) but also they be irregular 1n height (where the fold width varies and the distance remains cor: stant) or higher in their center. They may also be either straight or curved in center line. If their peripheries are thermally fused, a rounded periphery will result.
[0550] The materials of which the fixture 630 may be made includie resins (polyethylene tereph thalate, polypropylene, polyethylenee, polyacetal, nylon, acryl, ABS and AS), synthetic paper materials amd metals.
[0551] The volatile chemicals that can be used in the present inver- tion include an insect pest control agent (insecticide, repellen t, growth inhibitor, miticide, insect control essential oil or the like-), aromatic, aromatic deodorant, deodorant, fungicide, disinfectant or vermin repellent, and especially such a chemical that 1s volatile at aan ordinary temperature or air flow conditions. Such chemical may pre f- erably be at least one insect pest control agent selected from such specific chemicals as methofluthrin, empenthrin, terallethrin, tran s: fluthrin and profluthrin.
[0552] These chemicals are highly active and exhibit high deadly rates. Exhibiting efficaciousness in a small amount, they can desir.a bly be used and can be the optimum for use in a chemical cartridge smaller 1n size.
[0553] In addition to a chemical as mentioned above, there may koe added thereto where necessary a volatile adjustor (petrolatum, glycol etc), dissolving agent (paraffin, polyalcohol, fatty ester etc), antioxxi- _84—
dant, (BHT, BHA etc), indicator (a llochroic coloring agent) ard ultra violet absorber
[0554] As mentioned above, ways in which to re-supply a liquid chemical into a chemical cartridge used out may visually check an amount of its supply using a calibrated dropping pipette, =a dosage ampule, a metered container or a container with a metering cup, or a nozzle.
[0555] Also, since in supplying a chemical it is convenient if the time of its re-supply can visually be checked, it is desirable ®to use a chemical impregnated body 620 that may be of known type with an indicator displaying the time of its depletion.
[0556] An explanation is next ma de of an eight form of imp lementa- tion of the present invention. -
[0557] Referring to Fig. 65, there is shown a blower type chemical diffusing apparatus using a chemical impregnated body according to the present invention to diffuse c hemical volatilizing theref“rom into the environmental atmosphere.
[0558] In the apparatus shown, an apparatus or main cas.ing body 701 has an air blower 702, a battery 703 and a chemical cartmidge 704 including a chemical impregnated body 704 accommodated therein, wherein with a fan 702a rotated by a motor 702b, air @:s drawn through an air inlet port 705, passes through the chemicall impreg- nated body 704a and is discharged through an air discharge port 706 to emit chemical volatilizing from the chemical impregna ted body 704a and carried in air into the en vironmental atmosphere.
[0559] The apparatus casing body 701 has a portion 701la ogoposed to the chemical cartridge 704 where the latter can be detachecd and at- tached.
[0560] Made of a base member 707 and a cover member 7083, the ap- paratus casing body 701 is here designed, for example, to zallow the cover member 708 to be opened a.nd closed and the user to open the cover member 708 to remove the <hemical cartridge 704 and the bat- tery 703 and to fit them in positiom.
[0561] The chemical impregnated body 704a comprises a heoneycomb body 710 and an air permeable amd liquid absorptive sheet body 720 which are impregnated with a chemical.
[0562] The honeycomb beody 710 has a large number of cores 711 which are open at its bot_h side faces 710a and 710b in the direction its thickness.
[0563] The sheet body 72 0 is laid at one of these side faces, prefera- bly at the side, 710b, whee air flows out, over the side face.
[0564] Preferably, the honeycomb body 710 is much smaller in thick" ness than in width and length, namely a thin and “flat™ body that is large in planar area, having a large number of cores 71.1 open in the direction of its thickness, and over that large area the sheet body 720 is laid at its side where ai r flows out.
[0565] The cores 711 of t_he honeycomb body 710 may im cross section be not only polygonal bug also be, for example, corrugated, circular, triangular, square or triargular.
[0566] Further, the cores 711 may not only be laminar but also be spiral. The cores 711 may> be formed of a material that can be any of those of which the sheet bmody 729 may be formed as will be mentioned below.
[0567] These features m_ake it possible to make the chemical car- tridge 704 thin and henece the apparatus casing body 701 small in thickness.
[0568] Further, reinforced by the honeycomb body 7 19, the sheet body 720 can keep its given shape.
[0569] The honeycomb b ody 710 also permits air to fl ow through it smoothly and can effectiv-ely emit the chemical it retairas into the en- vironmental atmosphere without impeding the air flovw through the sheet body 720 1t reinforc es.
[05670] Also, being mourated on the apparatus casing body 701 as shown in Fig. 65, the hormeycomb body 710 and the shee=t body 720 al- low air to pass and flow through them, permitting the chemical held in them to be carried on air to emanate and diffuse int o the environ- mental atmosphere as the fan 702a is rotated as mentioraed above.
[0571] Also, the honeyco-mb and sheet bodies 710 and 7 20 of chemical impregnated body 704a wapon depletion of the chemical they have re- tained can be removed a s the chemical impregnated body 704a from _86—
the apparatus casing body 701, placed in the stacte that the sheet body 720 lies above the honeycomb body 710 and refilled with the chemical.
In this cas e, the sheet body 720 is supplied with liquid chemical by dropping li quid chemical at a limited area there of, the liquid chemical being then permeated progressively over the entire sheet body 720 and at the same time permeated into and through the honeycomb body 710 progre ssively over the entire honeycomb body 710 as well. There thus result s a chemical impregnated body 704a xefilled.
[0572] More specifically, since the sheet body 720 is disposed to lie over an en tire area in which a large number of walls 712 lie consti tuting the cores 711 of the honeycomb body 7E0 and oriented in the direction o fits thickness, the chemical is retaired upon impregnation or flooding on, along and into these walls 712.
[0573] Such a chemical cartridge 704 includimmg a chemical 1mpreg- nated body= 704a on reloading in the apparatus casing body 701 is al- lowed to ermit chemical into the environmental atmosphere.
[0574] Cheemical refilling by dropping liquid «<hemical on the sheet body 720 amllows chemical to be impregnated in to and retained by the honeycombo body 710 over its entire volume as well. Since the amount of chemica_l for refilling the sheet body 720 may be commensurate to that neede=d to impregnate the honeycomb and sheet bodies 710 and 720, it is p ossible to avoid waste of chemical.
[0575] It is therefor possible for the user to easily regenerate a chemical i mpregnate body 704a after use by refilling the honeycomb and sheet bodies 710 and 720 with chemical.
[0576] Wi th the sheet body 720 disposed in int imate contact with one of the sides faces (e. g., side face 710b) of the honeycomb body 710 in the direction of its thickness, the chemical supplied into the sheet body 720 is allowed to smoothly permeate into and throughout the honeycomb body 710 (i. e. the wall materials 71 2).
[0577] Witch the sheet and honeycomb bodies 720 and 710 so arranged, chemical is allowed to permeate from the sheet body 720 to the hon- eycomb bo dy 710 (i. e. wall materials 712) smoothly and without fail.
[0578] In this form of implementation, a retainer receptacle 730 is used to br-ing the sheet body 720 into intimate contact with one side _87—
face (e. g., side face 710b) of the honeycomb body 710.
[0579] The retainer receptacle 730 comprises a receptacle body member 7 40 and a hold member 750 each of which is in the form of a ring. The chemical impregnated body 704a is put in to the retainer re- ceptacle 7 40, and the hold member 750 is fitted into and coupled with the recep tacle body member 740 to hold the honeycomb and sheet bodies 710 and 720 by and between them with the sheet body 720 ly- ing in int imate contact with the one side face of thee honeycomb body 710.
[0580] This arrangement allows the sheet materia 1 720 to come into intimate contact firmly with one side face of the horaeycomb body 710.
[0581] Mention is next made of a first modification of the chemical cartridge 704 including the chemical impregnated b>ody 704a with ref- erence to Figs. 66 to 68.
[0582] The receptacle body member 740 comprises a central support section 7-41, a peripheral support section 742 and a plurality of stays 743 conn ecting the central and peripheral support sections 741 and 742 toget her wherein a space defined with the cent ral support section 741, the peripheral support section 742 and neigchboring stays 743 connected] together by the peripheral support section 742 is open con" stituting an air flow section 744 and the periphercal support section 742 has a raised support ring 745 made integral therewith.
[0583] T he hold member 750 is in the form of a rin g that can be fitted with the raised ring 745.
[0584] The honeycomb body 710 is fitted in the raised support ring 745 and the sheet body 720 is and placed on and supported by the upper surfaces of the central and peripheral support sections 741 and 742 and the stays 743 in contact therewith.
[0585] The hold member 750 is fitted with the r-aised support ring 745 and, coming into contact with a peripheral edge of the one side face 710=: of the honeycomb body 710, holds such peripheral areas of the hone ycomb and sheet bodies 710 and 720.
[0586] The central support section 741 is formed with a liquid chemical pool section 746 open in a support face 71, which section is open to the outside through an inlet port 747 form ed at its side oppo-
s ite to the support face 741.
[60587] In this arrangement, the chemical cartridge 704 (th e retainer r eceptacle 730) is taken out and placed upon turning it upsicle down. [#0588] And, chemical is dropped. and supplied through the inlet port 7 47 into the liquid chemical pool section 746 and pooled there.
[60589] This allows liquid chemic al to permeate from the certer of the o f the sheet body 720 progressi-vely over its entire area a.nd at the s ame time to permeate from the sheet body 720 through t he face of t he honeycomb body 720 in intimate contact with the sheet body 720, t hen into and through the sheet Body 720 progressively over its entire a_rea as well, [#0690] Mention is next made of =a second modification of the chemical ¢ artridge 704 including the chemical impregnate body 704a. [#0591] As shown in Figs. 69 to 7 0, the peripheral support section 742 o f the receptacle body member 7-40 is formed in its support face 742a warith an annular liquid chemical pool section 746 that is o pen in its leower face through an inlet port «47. [#0592] In this arrangement, liq uid chemical is supplied mnto a pe- r ipheral part of the sheet body amd is allowed to permeate teowards its ¢ entral part. [#0593] Mention is next made of a third modification of the chemical ¢ artridge 704 including the chemical impregnate body 704a.
[10594] As shown in Figs. 71 and. 72, the receptacle body member 740 iss formed in each of the central and peripheral support sections 741 a_nd 742 with a liquid chemical pool section 746 and an inlet port 747.
[0595] In this arrangement, lig-uid chemical is supplied irato both a ¢c entral and a peripheral part of the sheet body 720 so that ¢c hemical is a_llowed to permeate both its peripheral and central parts. T his allows ¢ hemical to fill the honeycomb body 710 efficiently in a short period of t ame.
[00596] While the sheet body 720 is shown above to lie abov e the hon- e ycomb body 710 to supply liquid chemical directly on the sheet body 7°20, alternatively the sheet body 720 may be positioned below the
Im oneycomb body 710 so that lig uid chemical is supplied from above t he honeycomb body 710 into the cores 711 and then supplie=d into the sheet body 720.
[0597] In this case, both the need to form the inlet port 74-7 shown in
Figs. 68 and 72 and the need to make the liquid chemical pool section 746 deep as shown in Figs. 68 and 72 are eliminated.
[0598] For example, in a fourth modification as shown in Figs. 73 and 74, a shallow liquid chemical pool section 746 is formed in each of the central and peripheral support sections 741 and 742.
[0599] And, liquid chemical is supplied from the cores 711 both in the central and peripheral parts of the honeycomb body 710 irato the cen- tral and peripheral parts of the sheet body 720.
[0600] Also, to identify where the chemical can be supplied, a ring collar may be applied on a hold section opposed to the liqu id chemical pool section to indicate that the chemical should be supplied there.
Alternatively, a color may be applied as an indication to those cores where the chemical should be supplied.
[0601] While in the preceding examples of implemen tation, the chemical impregnated body 704a is shown mounted so thaat the sheet and honeycomb bodies 720 and 710 lie inside and outside, x-espectively, they may be positioned vice versa, i. e., to lie outside andl inside, re- spectively.
[0602] For example, depending on types of chemicals used, the sheet body 720 may be positioned to face outwards and the hone ycomb body 710 to face inwards.
[0603] Also, while in the above examples of implemeratation, the chemical impregnate body 704a is shown having a sheet body 720 dis- posed to lie in intimate contact with one side face of a honeycomb body 710, two sheet bodies 720 may be used to lie in intinnaate contact with the two opposite side faces of a honeycomb body 'Z10, respec- tively.
[0604] The chemical that can be impregnated into a hone:ycomb body 710 of a chemical impregnated body 704a for use in the present in- vention may be an insect pest control agent (insecticide, repellent, growth inhibitor, miticide, insect control essential oil oer the like), aromatic, aromatic deodorant, deodorant, fungicide, disanfectant or vermin repellent, and especially such a chemical that is volatile at an ordinary temperature or air flow cond. itions.
[0605] Such chemicals, if used to k_ill insects, may be a variesty of volatile insecticides so far known, of which pyrethroid, carba mate, organophosphorus chemicals and so on can be listed, further of ~which pyrethroid chemicals can preferablys be used as generally hi gh in safety.
[0606] Further, such specific chemi cals as methofluthrin, tra nsflu- thrin, empenthrin, terallethrin and profluthrin which are high ly ac- tive and which in a small amount exhibit efficaciousness can d_esira- bly be used as they can make the che mical impregnated body thn and small.
[0607] The blank materials of which. a sheet body 720 may be formed include natural and chemical fiber s, nonwoven fabric (of natural, chemical and carbon fibers), resin ne=t (polyester, polypropylene . poly- vinyl chloride), cloth (woven or kn itted), paper yarn (pulp, inter, synthetic paper). The material may I»e a formed body such in the form of a sheet, net, honeycomb, drain bo ard, lattice or fold, a body yield- able to keep its shape when confined, or flocculate or sponge.
[0608] Of these materials, a sheet-Jdike material of nonwoven fabric that excels in air permeability and chemical retention is preferred.
[0609] In the present invention, w ays in which to supply a liquid chemical into a chemical impregnamte body may visually che=ck an amount of its supply using a calibsrated dropping pipette, a dosage ampule, a metered container or a comtainer with a metering cup, or a nozzle.
[0610] Also, since in supplying a cheemical it is convenient if th_e time of its re-supply can visually be checked, it is desirable to use a hon- eycomb body 710 in a chemical impr-egnated body 704 that max be of known type with an indicator displaysing the time of its depletiom.
