Description

Technical field

The present invention relates to a chemical cartridge for retaining a volatile chemical such as an insect, aromatic, deodorant or germicidal pest control agent and allowing the release or diffusion of said volatile chemical into an atmosphere from the chemical cartridge when used in a blower type chemical diffusion device.

Prior art

A blower type chemical diffusion apparatus is known as disclosed in JP 2002-291392 A.

Said blower type chemical diffusion apparatus is provided in its body with an air blower, a chemical receptacle (chemical cartridge) and a power supply container in which the air blower includes a fan and A motor, the chemical receptacle is stored a volatile chemical and the power supply container contains a battery.

And, the motor is driven to rotate the fan, which causes air to flow through the chemical receptacle, which in turn volatilizes the volatile chemical and diffuses it into the atmosphere.

As the volatile chemical and the battery are ineffective and end their useful lives with the use, the conventional blower type chemical diffusion apparatus of the type described above is designed to allow its replacement for continued use.

Therefore, for example, the power supply container is designed to contain the battery in a substitutable manner and to present the chemical receptacle mounted therein in a replaceable manner and to itself replaceably mount in the body of the apparatus so that the removal of the power supply container from the body of the apparatus makes it possible to replace the chemical receptacle and the battery.

This arrangement involves detachably interconnecting a plurality of elements from each other to allow replacing the chemical receptacle and the battery and therefore makes the structure complicated and expensive.

In addition, the need to remove the power supply container from the body of the apparatus and then remove the chemical receptacle and the battery from the removed power supply container for replacement requires difficult handling and gives rise to the possibility of that either the body of the appliance or the power supply container may be lost while dismantling with respect to each other.

In addition, the inability to connect the motor for the air blower mounted in the body of the apparatus to the battery housed in the power supply vessel by any cable requires a complicated structure to electrically connect them to each other.

In addition, a volume of chemical receptacle in the state in which it is filled with a large number of bodies impregnated with particulate chemicals in a porous receptacle body must have a large thickness.

This requires that the body of the apparatus have a large thickness.

A blower type apparatus for controlling harmful insects is also known as disclosed in JP 2001-197856 A.

An insect control apparatus of this type includes a chemical receptacle that retains an ingredient

or insect control component, a fan and an engine, all contained in a body of the apparatus (in the form of a chamber) which in turn has an air inlet and air outlet opening in which the rotation of the fan by the engine causes air to be drawn through the air inlet opening, impacting the chemical receptacle and exiting through the air outlet opening together with an insect control component into the atmosphere, emanating or thus spreading the insect control component into the atmosphere.

A conventional insect control apparatus of this type to make its insect control function effective when placed in a user and used outdoors, has its body formed with a pair of air outlet openings directed upwards. and down, respectively, so that when used in the user, the air containing the insect control component is expelled both up and down through the air outlet openings directed up and down respectively.

A conventional insect control apparatus of this type presenting its body of the apparatus formed with air outlet openings directed upwards and downwards so that when used placed on the user's waist can cause the air containing the component of insect control selectively exit both up and down is designed so that the insect control component reaches both the head and feet of the user. With such a conventional insect control apparatus formed simply with such outlet openings directed up and down only, however, a time is necessary for the insect control component to reach the user's head and feet and therefore it is not possible to control harmful insects since the device starts to be used.

In an open space such as in the open air in which the apparatus is used, the air currents produced by the wind flow and the movement of the user tend to fluctuate the discharged air flows and prevent them from diffusing towards target directions and They may not protect the user from being attacked by insects.

In addition, in a blower type chemical diffusion apparatus as disclosed in JP 2004-24161 A which is designed to aspirate air through an air intake or intake opening by means of an air blower and to cause the chemical that is volatilized from a chemical receptacle (chemical cartridge) to exit through an air discharge opening together with the aspirated air, as shown in Figures 23 and 24, the body of the apparatus 241 is formed in its upper part with the suction opening 242 to aspirate air and on its two opposite sides with such air discharge openings 243 to emanate the chemical entrained in the aspirated air. And, the suction opening 242 in the upper part of the body of the apparatus 241 is provided with the chemical or receptacle that houses the chemical 244 in which the chemical is retained. This chemical receptacle 244 is formed both in its upper and lower part with grooves 245 that open in the form of annular rings (or annular growth rings of a tree) through which air flow is allowed. In addition, the body of the apparatus 241 is provided inside the air blower 246 and has battery cells 247 housed on two opposite sides of the air blower 246, respectively, as a power source for moving the latter.

With the apparatus 241 realized in this way, the air blower 246 constructed therein to operate energized by the battery cells 247 draws air from the suction opening 242 at its top through the chemical receptacle 244 and causes the air sucked into and beyond the chemical receptacle 244 while carrying the chemical that volatilizes therein and diffuses through the air discharge openings 243 on its lateral faces towards its surroundings.

On the other hand, the body of the apparatus 241 has a positioning strap 248 attached thereto to allow its placement on the wrist or the like of a user. A positioning strap 248 of this type is flexible, thin and elongated and has a buckle 249 at one of its ends with which the body of the device 241 can be placed on the wrist or the like of the user, thereby allowing the use of the device of diffusion of blower type chemical products object adjusted on the wrist or similar.

A conventional blower type chemical diffusion apparatus of this type therefore requires that its body of the apparatus include a chemical receptacle containing a volatile chemical, an air blower for diffusing the volatile chemical from the receptacle. of chemical towards the environment and also a battery as a power source to energize the air blower as the heaviest component. As a result, the body of the apparatus tends to have a large size and a high weight, giving rise to the possibility that the user may find it difficult to use the apparatus. Especially in the case that the diffusion apparatus of the object blower type chemical products is used placed on the wrist or the like, the user can perceive it as unpleasant with the perception of its size and weight.

A blower type chemical diffusion apparatus is also known as disclosed in JP 2002-291392 A.

In a blower type chemical diffusion apparatus of this type, its apparatus body includes an air blower, a chemical cartridge and a power supply container in which the air blower has a fan and a motor , the chemical cartridge comprising a porous receptacle containing a large number of bodies impregnated with particulate chemicals impregnated with a chemical, and the power supply container houses a battery.

And it is conceived in such a way that the rotation of the fan with the motor causes the air to pass through the receptacle and emanates with the chemical dragged therein into the atmosphere.

A conventional chemical cartridge as mentioned above comprises a porous receptacle that requires containing a large number of bodies impregnated with particulate chemicals impregnated with a chemical must have a large thickness, which requires that a chemical cartridge of this type present a large thickness.

As a result, a blower type diffusion chemical apparatus of this type that requires that a chemical cartridge, an air blower and battery cells be mounted within its body of the apparatus must be of overall thickness as a whole.

In addition, the conventional chemical cartridge as mentioned above comprises a porous receptacle containing a large number of bodies impregnated with particulate chemicals impregnated with a chemical, and the chemical in these bodies impregnated with volatile particulate chemicals. it drags with the air that passes through the receptacle and emits progressively into the atmosphere. When the chemical impregnated in the bodies impregnated with chemicals is exhausted, the receptacle that presents the bodies impregnated with particulate chemicals is disposed of as waste.

Chemical cartridges of this type that therefore require disposal as waste when consumed, are currently unfavorable in social circumstances such as energy saving and waste problems.

A body impregnated with chemical is also known as disclosed in JP 2001-200239 A.

This chemical impregnated body comprises a plurality of chemical carrier networks comprised of braided wires and arranged one above the other in which each of these networks is impregnated with a chemical.

A body impregnated with conventional chemical can be prepared as mentioned above in which a plurality of networks are arranged one above the other, but it can make it difficult for the user to use this body impregnated with chemical because it has a plurality of networks. arranged on top of each other and can also cause a user's hand to get stained with the chemical coming from a body impregnated with this type of chemical when it is held by hand.

When the chemical impregnated in the networks is depleted, the networks are discarded as waste as the chemical cartridge mentioned above. A body impregnated with chemical of this type is unfavorable in social circumstances currently such as energy saving and waste problems.

It is also known a chemical cartridge as disclosed in the design register JP No. 1173150.

This chemical cartridge comprises a receptacle defined by an outer shell that has an opening and an inner shell that has an opening in which a large number of bodies impregnated with particulate chemicals impregnated with a chemical are housed in a space between the external and internal housings.

This chemical cartridge that is designed to contain bodies impregnated with particulate chemicals impregnated with a chemical in a limited part of the volume of the cartridge through which air is passed to carry away the chemical that volatilizes in it for diffusion into the atmosphere, it is limited in the amount of chemical that it can contain per unit volume and if it is enlarged it must have a larger diameter, thus making the body of the cartridge larger together.

As a result, such a chemical cartridge requires a large space to accommodate it in a blower type chemical diffusion apparatus and therefore makes the apparatus body present a large size.

JP 2002-291392 mentioned above also discloses a body impregnated with chemical that uses a large number of carrier particles impregnated with a chemical and retained in a porous receptacle.

As a result, this requires that the receptacle have a large size and therefore also a large thickness, again making the body of a blower-type chemical diffusion apparatus together present a large size.

On the contrary, the body impregnated with chemical if it is made in the form of a sheet as a carrier impregnated with a chemical and thus retaining the chemical can be thin enough to keep the body of the apparatus sufficiently thin.

However, a body impregnated with chemical produced in this way in the form of a sheet is so weak with respect to its rigidity that it cannot maintain its own given shape. Therefore, an attempt is made to maintain a given form of a body impregnated with chemical by supporting it in its intermediate, outer peripheral and central areas with its retention receptacle.

These areas of the body impregnated with chemical supported by the retention receptacle have a large surface area and become completely useless when serving to emanate and diffuse the chemical impregnated in these areas because the air cannot pass Through the zones.

A chemical impregnated body is also known in this regard as disclosed in JP H11-92303 A which is in the form of a honeycomb honeycomb impregnated with a chemical that is more resistant to its stiffness. and larger than the amount it contains of chemical per unit volume than the body impregnated with sheet-like chemical.

However, either honeycomb foil or honeycomb type, a body impregnated with conventional chemical of this type once used or spent in a blower type chemical diffusion apparatus to diffuse a chemical into the atmosphere must be discarded as waste.

Such a body impregnated with a conventional disposable chemical is unfavorable in social circumstances currently from the point of view of waste and resource savings.

For this reason, it is conceivable to make a body impregnated with spent chemical reusable by impregnating it with chemical so that it retains the chemical again.

Then, while it is possible for a body impregnated with spent chemical to be reusable especially if it is a drip type to impregnate it with a chemical and to retain the chemical again, to impregnate a honeycomb impregnated body of shaped honeycomb To include a large number of cores, using a chemical requires submerging the honeycomb honeycomb body in a container filled with a large amount of chemical or continuing to provide a large amount of chemical and for a period of time sufficient to reach the impregnation required. Not only does this require a large amount of such a chemical, but a specialized facility to handle the chemical will also be mandatory.

Therefore, although a large number of bodies impregnated with chemical products can be re-impregnated with a chemical and thus make them reusable successively as in a factory or production plant without difficulty in meeting these requirements, it is generally impractical for an individual user try to make a conventional spent chemical cartridge or retainer element reusable because too much chemical is wasted and cannot be handled.

Description of the invention

An objective of the present invention is to provide a thinned chemical cartridge, which can maintain its given shape, which is easy to handle and does not contaminate the hands of a user and which when spent can be filled with chemical and can return to be used again and again.

In a first aspect there is provided a diffusion apparatus for chemical products of the blower type which is not part of the present invention which has an apparatus housing body, an air blower, a chemical cartridge and a battery, in which The apparatus housing body comprises a homologous first and second-sided housing body coupled together so that they can be opened by a hinge, the first-sided housing body presenting a blower mounting recess, a flow section of air and a recess to accommodate the battery, the second-side housing body having an air flow section separated from the air flow section in the first-side housing body; the air blower has a fan adapted for rotation by means of a motor, the fan and the motor being mounted in the blower mounting recess; the chemical cartridge is disposed between the air blower in the first side housing body and the air flow section in the second side housing body; the battery is removably housed in the recess that houses the battery; the recess that houses the battery and the blower assembly are spaced apart in a planar direction and placed so as not to overlap in a direction of their thicknesses; and the chemical cartridge contains a chemical impregnated body that has a carrier in the form of a sheet impregnated with a chemical.

A blower-type chemical diffusion apparatus in this aspect, which allows the chemical cartridge and the battery to be removed in the first-sided homologous housing body and recharged simply by opening the second-sided homologous housing body with respect to the hinge From the first-sided homologous housing body, it is simple and structurally reduced in cost to allow these consumer items to be renewed.

Since the opening of the second-sided complementary housing body makes it easy to replace the chemical cartridge and the battery, its replacement is simple. Moreover, then, with these two homologous housings held coupled to each other, in no way can any of them be lost.

In addition, since the motor and the fan battery are placed in the first-sided homologous housing body as a common housing, it is generally easy to connect them electrically; The motor and battery can be connected electrically easily.

In addition, since the chemical cartridge is thin and the chemical cartridge and the battery are positioned without overlapping in a direction of their thicknesses, the entire apparatus is thinned.

In a blower type chemical diffusion apparatus as set forth above, the apparatus housing body may be formed with a hook coupling section to which a hook of a hanging auxiliary element and a hole in the device can be attached. that a fitting section of the hanging auxiliary element can be fitted.

This feature allows the device to be used while it is hanging or resting on a table or similar.

In a second aspect there is provided a blower insect pest control apparatus which includes: an apparatus housing body having an air inlet opening and first and second air discharge openings, and a receptacle chemical, a fan and a motor in the device housing body, the chemical receptacle retaining a chemical impregnated body impregnated with an insect pest control component, allowing the fan to rotate through the motor that the air is drawn through the air inlet opening and the air intake to impact the chemical impregnated body in the chemical receptacle and the air inlet of the insect pest control component from the body impregnated with chemical for its emanation and diffusion in an atmosphere of the environment, characterized in that: the first and second discharge openings ga air are each in the form of a hole that has a radial length and inclined in a circumferential direction in which the fan rotates, so that when the apparatus is used with the apparatus housing body arranged in a user, The air is discharged up through the first air discharge opening and down through the second air discharge opening.

A blower-like insect pest control apparatus in this regard, which allows air containing an insect pest control component to be forcedly discharged through the first and second air discharge openings, can be advantageously applied. when the device is used with its housing body placed on the user's wrist because the air containing an insect pest control component is allowed to forcefully exit through the first and second air discharge openings and by Both are allowed to reach the user's head and feet quickly.

This provides an apparatus that acts effectively since it begins to be used.

In a blower insect pest control apparatus as set forth above, the first and second air discharge openings can each be in the form of a hole that communicates its inner entrance opposite the fan with its outer outlet opening on an outer face of the apparatus housing body and in which the hole has an upstream side guiding face that connects a side entrance hole edge upstream of the interior entrance and a side exit hole edge upstream of the outer outlet continuously with each other and a side guide side downstream that connects the side entrance hole edge downstream of the inner entrance and a side outlet hole edge downstream of the outer outlet continuously with each other, the faces being of lateral guidance downstream and lateral upstream each inclined towards a circumferential direction in which the fan rotates.

With each side guidance side upstream and downstream inclined towards a circumferential direction in which the fan rotates according to this characteristic, air containing the insect pest control component can be emitted not only in a forced but also in a gentle manner.

In a blower insect pest control apparatus as set forth above, the apparatus housing body may be configured to comprise a base element having the first and second air discharge openings and a chamber that houses the fan, a cover element that presents the air inlet opening and removably attached to the base element on one of its sides in a direction of its thickness and a chamber that houses the chemical disposed between the base and the elements of covered and open towards the chamber that houses the fan. Then, the base element may be formed with a chamber that houses the motor and a chamber that houses the battery that open on a rear face of the base element on its side opposite the cover element; and the chambers that house the motor and the battery may be adapted to accommodate the motor and the battery, respectively, and positioned so that the motor and the battery do not overlap in a thickness direction of the base element.

This feature allows the cover element to be removed to allow the chemical receptacle to be removed. In addition, since the motor and the battery are arranged so that they do not overlap in a direction of the thickness of the base element, the entire apparatus can become thin.

In a blower insect pest control apparatus as set forth above, the apparatus housing body may be additionally formed with a third air discharge opening to discharge air that drives the insect pest control component into the same, the third air discharge opening being in the form of a hole having a radial length and being inclined towards a circumferential direction in which the fan rotates so that when the apparatus is used with the apparatus housing body placed In a user, the air is discharged obliquely up or obliquely down through the third air discharge opening.

According to this characteristic, since air containing the insect pest control component is allowed to flow out through the third air discharge opening obliquely upwards or obliquely downwards, it is possible to send the insect pest control component more either towards the head or the feet than towards any other place.

In a blower insect pest control apparatus as set forth above, the third air discharge opening may be in the form of a hole communicating its internal inlet opposite the fan with its external outlet open on an external face of the apparatus housing body and in which the hole has an upstream side guiding face that connects a side entrance hole edge upstream of the internal entrance and a side exit hole edge upstream of the external outlet so it continues with each other and a side guide side downstream which connects a side of the side entrance hole downstream of the internal entrance and a side of the side exit hole downstream of the external outlet continuously with each other, each face being lateral guidance upstream and downstream inclined towards a circumferential direction in which the fan rotates.

According to this characteristic, air containing the insect pest control component can be discharged not only in a forced manner but also in a gentle manner.

In a blower insect pest control apparatus as set forth above, the apparatus housing body is formed with an auxiliary air discharge opening adapted to discharge air laterally when the apparatus is used with the housing element. device placed in a user, thus allowing the device to emit air in all directions including up and down.

According to this characteristic, when the apparatus is used placed in the user, the insect pest control component can spread evenly around the user.

In a blower insect pest control apparatus as set forth above, the auxiliary air discharge opening may be greater in terms of air resistance than the first and second air discharge openings or discharge openings air first, second and third.

This feature can be applied advantageously when the device is used placed on the user's waist because air containing the insect pest control component can be emitted in a less forced but adequately lateral way with respect to the user and at the same time sufficiently forced to his head and feet.

In a blower insect pest control apparatus as set forth above, the auxiliary air discharge opening may be in the form of a hole that communicates its internal inlet opposite the fan with its external outlet open on an external face of the apparatus housing body and in which the hole has an upstream side guiding face that connects a side entrance hole edge upstream of the internal entrance and a side exit hole edge upstream of the external outlet so it continues with each other and a side guide side downstream which connects a side of the side entrance hole downstream of the internal entrance and a side of the side exit hole downstream of the external outlet continuously with each other, each face being lateral guidance upstream and downstream inclined towards a circumferential direction in which the fan rotates. Then, the auxiliary air discharge opening may be less open in the direction of rotation of the fan than the first and second air discharge openings or the first, second and third air discharge openings.

According to this characteristic, air can be forcedly discharged through the first and second air discharge openings or first, second and third without fail while air is less forcedly discharged through the auxiliary air discharge opening without fail.

In another aspect, a blower type chemical diffusion apparatus is provided which has an air blower and a chemical receptacle in which a volatile chemical is stored, comprising: an apparatus housing body in which it sucks air through the fan through an air inlet opening and is discharged through an air discharge opening while the chemical from the chemical receptacle is dragged into it; a power housing body separated from the device housing body to contain a power source for the air blower in the device housing body; and a connection cable for connecting the device housing body and the feeding housing body to each other and for electrically energizing the air blower in the device housing body from the power supply in the housing body of feeding.

A blower type chemical diffusion apparatus in this aspect is designed to separate the power supply section (battery) as the heaviest component from the other components and for inclusion separately in a power housing body and a device housing body and thereby to reduce the device housing body both in size and weight so that it can be conveniently placed on the user's wrist. Then, the feeding carcass body can be placed separately, for example, in a pocket in pants or a suit, thereby allowing the apparatus to be used comfortably preventing the unpleasant sensation that the user had when wearing the apparatus. Conventional large size and weight. In addition, a connection cable is conveniently provided as set forth.

In a blower type chemical diffusion apparatus as set forth above, a connection cable as set forth may be advantageously such that it can be removably attached to the apparatus housing body and / or the body of power housing

This feature allows the connection cable connected first to only some or none of the apparatus and the power housing bodies to each other or both only after adjustment, thereby greatly facilitating their individual adjustment operations.

In a blower type chemical diffusion apparatus as set forth above, it may have adjustment means for adjusting the apparatus housing to an object to be adjusted.

In a blower type chemical diffusion apparatus as set forth above, it may have adjustment means for adjusting the feed housing to an object to be adjusted.

In a blower type chemical diffusion apparatus as set forth above, it may have adjustment means for adjusting the connection cable to an object to be adjusted.

These characteristics allow the blower type chemical diffusion apparatus to be easily configured by means of the proper adjustment of the apparatus housing body, the feeding housing body and the connecting cable individually.

A chemical cartridge is provided in another aspect, comprising: a body impregnated with chemical in the form of a sheet that absorbs liquid and permeable to air impregnated with a chemical; a retention receptacle for retaining the body impregnated with chemical product, the retention receptacle having a clamping section for holding an upper and lower face of the body impregnated with chemical through it and an air passage section through which air flows; and a space formed between the clamping section and the body impregnated with chemical and that is opened to the outside through an air flow section formed in the clamping section.

According to this aspect, a thinned chemical cartridge is provided using a chemical impregnated body that is thin in the form of a sheet held by a retention receptacle that also serves to maintain its given shape and to protect the hand from contamination by the chemical product.

In addition, a volume of chemical retained in the areas of a chemical-impregnated body where the retention receptacle contains it and where there is no direct air flow, is admitted to the indicated space in which it is carried in air flowing in the same and then it is discharged into the surrounding atmosphere. Therefore, substantially no volume of chemical retained in the body impregnated with chemical will become of little use.

In a chemical cartridge as set forth above, the clamping section may have: a recess formed where the clamping section is in contact with a lower face of the body impregnated with chemical; a space formed between the recess and a lower face of the body impregnated with chemical; and an air flow hole formed where the clamping section is in contact with an upper face of the body impregnated with chemical, so that it opposes the recess, thus providing an air flow section.

According to this configuration of the chemical cartridge, the recess can be used to accumulate a liquid chemical discharged therein through the air flow orifice. The accumulated liquid chemical in the recess is allowed to permeate inside the body of progressively depleted chemical and thereby regenerate in a chemical impregnated body.

A chemical cartridge is still provided in another aspect, comprising: a body impregnated with chemical in the form of a sheet that absorbs liquid and permeable to air impregnated with a chemical; and a retention receptacle having a receptacle base element and a cover element for holding a body impregnated with chemical in which: the receptacle base element comprises a central support section, a peripheral support section and a plurality of intermediate support sections connecting the central support section with the peripheral support section to form an air flow passage section, the receptacle base element being formed with a recess in at least one of the upper faces of the central, peripheral and intermediate sections and with a space between this recess and a lower face of the body impregnated with liquid, the cover element comprises a central clamping section, a peripheral clamping section and a plurality of intermediate clamping sections that connect the central clamping section and the peripheral clamping section to each other to form a air flow passage section, the cover element being formed with an air flow hole in at least one of the central, peripheral and intermediate clamping sections so as to oppose the recess, whereby the element of receptacle base and cover element can be detachably adjusted and coupled to each other to allow air to flow through the air flow passage section in the receptacle base element and the air flow passage section in The cover element.

Again in this case, a chemical cartridge is provided which can be thin, which can keep a body impregnated with chemical in its given form and which can protect the hand from chemical contamination.

Furthermore, with its central, peripheral and intermediate sections fastened with the central support and support section, the peripheral support and support sections and the intermediate sections of the receptacle base and the cover elements, a body impregnated with thin chemical can Hold firm and is also easy to handle and maintain.

In addition, a volume of chemical retained in at least one area of a body impregnated with chemical in which it is held by a support and a clamping section and where there is no direct air flow is admitted to the indicated recess in which it drags in air that flows in it and then discharges into the surrounding atmosphere. Therefore, substantially no volume of chemical retained in the body impregnated with chemical will become of little use.

The recess, again in this case, can be used to accumulate a liquid chemical poured into it through the air flow hole. The accumulated liquid chemical in the recess is allowed to permeate inside the body of progressively depleted chemical and thereby regenerate in a chemical impregnated body.

In a chemical cartridge as set forth above, the receptacle base element may be formed with a recess in the central support section and an annular recess in the peripheral support section.

According to this characteristic, the annular recess in the peripheral support section allows the liquid chemical to permeate inside the body of spent chemical from its global periphery evenly throughout its entire area.

In a chemical cartridge as set forth above, the central, peripheral and intermediate support sections are identical in shape and size to the central, peripheral and intermediate clamping sections, respectively, so that the flow passage sections of Air are identical in shape and size with each other.

This configuration allows air to flow smoothly along the air flow passage sections of both the base of the receptacle and the cover elements and therefore that the chemical in the body impregnated with chemical emanates and diffuses towards the surrounding atmosphere in a smooth and effective way.

The present invention provides a chemical cartridge according to the appended claim.

A chemical cartridge of this type, again in this case, is advantageous because it can be refilled after use. For this purpose, liquid chemical is supplied to the recess in the central area of the retention receptacle, and the liquid chemical accumulated in this recess of the retention receptacle is allowed to permeate towards its periphery and then into the sheet body so uniform throughout its entire area.

Therefore, a chemical cartridge can be used again and again.

In addition, being placed in the center of the retention receptacle, the recess of liquid accumulation in no way prevents the flow of air from the fan which can therefore be used without waste and effectively used to diffuse the chemical into the surrounding atmosphere .

In addition, with the body impregnated with thin chemical in the form of a sheet retained by a retention receptacle, the chemical cartridge can be thinned.

In addition, a chemical receptacle as defined above is suitable for maintaining a chemical receptacle in its given form and also does not contaminate the hand with chemical.

In a chemical cartridge as set forth above, the retention receptacle may be formed in a peripheral area with a liquid accumulation recess such that the liquid chemical stored in the liquid accumulation recess is allowed to permeate a central area of the sheet. The retention receptacle is formed in a peripheral zone with a liquid accumulation recess such that the liquid chemical stored in the liquid accumulation recess is allowed to permeate towards a central area of the sheet.

This configuration allows the liquid chemical supplied to and stored in the liquid accumulation recess in a central area of a body to permeate its peripheral zone and the liquid chemical supplied to and stored in the peripheral zone to permeate to the central zone. Therefore, even a large body can be impregnated with a relatively large chemical.

In a chemical cartridge as set forth above, a peripheral fluid accumulation recess formed by a peripheral recess formed in the peripheral support section and a peripheral supply section formed in the peripheral fastener section may be present.

With its central and peripheral sections fastened between the base of the receptacle and the cover elements in this case, the chemical impregnated body can be firmly held in a chemical cartridge, facilitating its handling and maintenance.

In another aspect a chemical cartridge is provided comprising: a body impregnated with chemical in the form of a sheet and a retention receptacle containing the body impregnated with chemical in which: the body impregnated with chemical comprises a carrier in the form of a sheet that absorbs liquid and permeable to air that has a zone of high liquid retention located and impregnated with a chemical.

In this case, the body being impregnated with thin chemical in the form of a sheet and being held by its retention receptacle, a chemical cartridge can be provided that is easy to handle.

A chemical cartridge thus constructed is, in this case also, advantageous because when its chemical is depleted after use, chemical can be returned to the carrier in the area of high liquid retention. It is then allowed that the liquid chemical impregnated in the high liquid retention zone of the carrier progressively permeate throughout the body, thereby regenerating it to give a body impregnated with new chemical. Therefore, a chemical cartridge can be used again and again.

In addition, the carrier can accept a large amount of liquid chemical in its high liquid retention zone at once. The liquid chemical supplied in the area of high liquid content can then permeate therein progressively throughout its entire area. Therefore, a uniformly impregnated body is regenerated with a retained chemical.

In a chemical cartridge as set forth above, a part of the carrier may be thicker than its remaining parts to constitute the high liquid retention zone.

Thus, the upper high liquid retention zone can provide a sign that can be visually observed if liquid chemical has been supplied.

In another aspect a chemical cartridge is provided comprising a body impregnated with chemical in the form of a folded flat sheet material having a large number of impregnated folds with chemical, the folds are formed by mountain-shaped folds and Alternate valley-shaped folds of the sheet material at certain widths, the sheet material itself being absorbing liquid and permeable to air, the folded sheet material presenting a joined peripheral zone to prevent the folds from losing shape.

With a chemical cartridge thus manufactured, its body impregnated with chemical can retain an increased amount of chemical per unit volume, and the cartridge itself can therefore have a smaller size.

In particular, a chemical cartridge can therefore be provided that retains a large amount of chemical but is thin.

A folded sheet material whose periphery is treated to prevent the folds from losing their shape allows air to flow substantially uniformly throughout their entire area and therefore to diffuse chemical substantially substantially from the body impregnated with chemical full.

Better ways to practice the invention

At the beginning, an embodiment is mentioned that is not part of the present invention.

Referring to Figures 1 to 4, a blower type chemical diffusion apparatus includes a main body of housing or apparatus 1, and an air blower 2, a chemical cartridge 3 and a battery 4 that are connected in the main housing body 1.

The casing main body 1 comprises first and second interconnected homologous casing elements 10 and 11 so that they can be opened by a hinge 12 so that the casing main body 1 can be opened and closed.

The first housing element 10 has an extremely small thickness compared to its planar size, specifically of thin plate type. It is formed with a blower mounting recess 13, open air passages 14 towards the blower mounting recess 13 and a recess that houses the battery 15. The blower mounting recess 13 and the recess to accommodate the battery 15 are open each towards an inner side side face 10a of the first housing element 10 and are separated from each other in a plane thereof so that they are not located one above the other in a thickness direction. The air passages 14 open the blower mounting recess 13 towards an external surface 10b of the first housing element 10.

The second housing element 11 has an extremely small thickness compared to its planar size, specifically of thin plate type. It can take two positions, that is, one in which it covers and the other in which it discovers, both the blower mounting recess 13 and the recess that houses the battery 15. The second housing element 11 is formed with air passages. 16 in an area thereof that opposes the blower mounting recess 13 of the first housing element 10.

The air blower 2 includes a fan 20 and a motor 21 mounted as received within the blower mounting recess 13 and is designed so that the rotation of the fan 20 by the motor 21 when the second housing element 11 is in its closed state causes air to flow through the air passages 14 of the first housing element 10 and the air passages 16 of the second housing element 11.

For example, air can be drawn through the air passages 16 of the second housing element 11 and discharged through the air passages 14 of the first housing element 10 into the atmosphere, or vice versa.

The chemical cartridge 3 includes a chemical impregnated body that is a carrier in the form of a sheet impregnated with a chemical that is placed on an annular edge in the blower mounting recess 13 and, when the second housing element 11 is brought to its closed position, held against the annular edge with an internal face 11b thereof.

The recess that houses the battery 15 provides a space in which the battery 3 in the form of dry batteries can be removably placed.

With the apparatus configured as mentioned above, bringing the second housing element 11 to its open position in relation to the first housing element 10 allows to remove, place in place and exchange the cartridge 3 and the battery 4.

And bringing the second housing element 11 to its closed position in relation to the first housing element 10 followed by driving the motor 21 to rotate the fan 20 allows air to pass through the chemical impregnated body in the product cartridge chemical and that air that presents chemical product dragged into it emanates and diffuses into the surrounding atmosphere.

In addition, the device housing body 1 even in its closed position has an extremely small thickness in comparison to its planar size, specifically thin and plate-like. In this case, its planar size is as large as slightly larger than that of the fan 20 and the battery 4, specifically a planar size without practically presenting no other area than the area in which the fan 20 and the battery 4 can only be housed inside. of the casing body of apparatus 1 (therefore, omitting any planar space without utility).

Therefore, the device casing body 1 is manufactured thin and compact, which allows the blower type chemical diffusion apparatus to be manufactured thin and compact.

The handling of the apparatus is thus facilitated and that its required molds have a smaller size and that the storage material is smaller, thus also reducing its manufacturing cost.

Specifically, as observed in its planar form, the apparatus housing body 1 comprises a first zone 1a that is almost circular, a second zone 1b that is almost rectangular and a third zone or intermediate zone 1c that interconnects the first and second 1a and 1b, and as a whole it is almost rectangular except for the first zone 1a that is almost circular.

The first almost circular zone 1a has a planar size that is slightly larger than the external diameter of the fan 20, the second almost rectangular area 1b has a planar size that is slightly larger than that of the battery 4 and the intermediate zone 1c is in the planar shape of a pair of triangles simply to make the first and second zones contiguous so that there is no useless space in the contour and volume of the apparatus.

As a result, the apparatus housing body 1 presents its appropriately convex and concave surface contour, aesthetically emphasizing its overall shape and making the apparatus visually appealing to the user.

On the contrary, the housing body of such a conventional apparatus is monotonous in its surface contour without an emphasis of this type so that its appearance was not very attractive to the user.

The air passages 14 can be formed not only in the first zone 1a but also on both sides of the intermediate zone 1c so that it can emanate and diffuse chemical towards a greater number of directions.

Additional configurations of the device components are mentioned below.

The first carcass element 10 includes an outer sheath 17, an inner sheath 18 and an inner plate 19. The outer sheath 17 has a disk shape comprising a surface plate 17a provided with side plates 17b along it and formed with air passage notches 50 and also with a first and second coupling section 51 and 52.

The inner liner 18 comprises a base plate 18a provided with a side plate and fits into the outer liner 17.

The base plate 18a is formed with a recess 53 open towards the surface plate 17a of the external lining 17. The motor 21 is received and mounted in its position in the recess 53 from which its output shaft 21a protrudes passing through of the base plate 18a and presents the fan 20 attached thereto. The fan 20 is in this case a Sirocco fan but it can be a propeller fan or the like.

The side plate 18b is provided with a plurality of suction guides 54 and also with a coupling section 55 for coupling with the coupling section 51.

The internal plate 19 has an annular recess 56 defining a circular opening 57 and is formed with a coupling section 58 for coupling with the coupling section 52 of the external lining 1 to cover the fan 20.

The configuration described above allows the air blower 2 to be easily placed in its position in the first housing element 10, specifically housing and mounting the motor 21 in position in the recess 53 of the inner liner 18 and fitting the inner liner 18 into this state in the external lining 17, followed by the union of the fan 20 and then adjusting the internal plate 19. This structure is not only easy to assemble but also has a pleasant appearance with the motor 21 out of sight by the external lining 17.

The outer sheath 17 and the inner sheath 18 also constitute the recess that houses the battery 15.

The second housing element 11 has a disk shape comprising a surface plate 11b provided with a side plate 11c, which is formed with the coupling section 59 that is designed to engage with the coupling section 55 of the inner liner 18. The surface plate 11b has a round raised area 11d formed with the air passages 16, for example, in the form of a plurality of grooves as shown.

The side plate 17b of the outer lining 17 in the first housing element 10 is formed halfway along its length with a notch 17c while the side plate 11c of the second housing element 11 is also formed halfway along its length with a notch 11e, these notches being formed opposite each other to provide air passages 14, as shown in figure 1.

The chemical cartridge 3 includes a round disk-shaped receptacle 30 with an open side, a chemical-impregnated body 31 with a disk-shaped shape loaded in this round receptacle 30 and a round lid 32 embedded in the latter. In this case, the round receptacle 30 and the round lid 32 are formed with air passages 30a and air passages 32a, respectively.

The chemical-impregnated body 31 is a chemical carrier in the form of a thin or sheet-like disk impregnated with a chemical.

The round receptacle 30 is placed in the annular recess 56 of the inner plate 19 to fit and be carried by it. Then, by bringing the second housing element 11 to its closed position, its raised round area 11d is placed in opposition to the round cover 32.

This places the round receptacle 30 (and the chemical cartridge 3) firmly in position in the housing body of apparatus 1.

The air blower 2 and the battery 4 are separated from each other in the planar position and do not overlap in the thickness direction while the chemical cartridge 3 using a carrier or body impregnated with chemical in the form of a sheet is thin.

In combination they give rise to a diffusion apparatus for chemical products of the blower type which together is thin.

The housing body of apparatus 1 so that it can be used in suspension is provided on its side face with a suspension clip 60 and also on its lower face with a suspension opening 61, which can alternatively be used for engagement.

The suspension clip 60 can be formed, for example, by a U-shaped part 62 raised in relation to and made integral with one of the side plates 18b of the inner liner 18 in the first housing element 10 of the device housing body 1 .

The suspension opening 61 may be formed in an almost L-shaped connection piece 63 raised in relation to and made integral with the surface plate 17a of the external lining 17 in the first housing element 10 of the apparatus housing body 1.

As shown in Figures 5 and 6, a hanger (suspension tool) 64 having a first hook 60 and a second hook 66 can be used to engage parts 62 and 63 for the suspension clip 65 and the suspension opening 61, respectively.

Thus equipped as mentioned above, a diffusion apparatus for chemical products of the blower type according to the present invention can be carried by the user hung on the hanger 64 which, as shown in Figure 5, can be hung in turn from the belt that carries the user.

In addition, the use of the hanger 64 as a fall protection for the device housing body 1 after inserting the hook 66 into the opening 61 and erecting the housing body 1 longitudinally to be in a support plane as shown in the Figure 6 allows the use of a diffusion apparatus for chemical products of the blower type according to the present invention resting on the floor, a table or the like.

In addition, a rope can be attached to the suspension clip 60 and then used to hang the apparatus from a wall or the like or from a body part or a garment of the user's clothing.

In addition, the device that is therefore thin and compact can be easily manipulated by any user from a child to an elderly person, with its housing body attached to the wrist, neck, arm or leg.

In Figures 1 and 4, a switch 5 and a lamp 6 are also shown. The switch 5 is turned on and off to energize and de-energize the motor 21 while the lamp 6 turns on and off, respectively.

The sheet-like carrier used impregnated with a chemical is representatively made of a porous paper, fabric, net material or woven or non-woven textile material. Considering its stability when placed, it is desirable that the body impregnated with chemical for its use is firmly held by a receptacle and its cover or cover part, for example, an outer peripheral part of the body impregnated with sheet-type chemical with a resin or similar. In addition, considering its portability, it is desirable that the carrier is a thin sheet having a thickness of 2 to 5 mm and an area of 700 to

2

3,000 mm

The chemical for use in the present invention may be an insect pest control agent such as an insecticide, acaricide, parasite or pest repellant, parasite growth retardant or suction inhibitor, aromatic agent, deodorant or bactericidal , and must be volatile.

Such chemicals, if used to kill insects, may be a variety of volatile insecticides known to date, of which pyrethroid chemicals, carbamates, organophosphorus, etc., can be listed, of which pyrethroid chemicals can be used. preferably with generally high security.

In addition, specific chemicals such as metoflutrin, transflutrin, empentrine, teraletrin and proflutrin that are highly active and that in a small amount show efficacy can be used as they can make the chemical carrier thin and small.

The power supply for the motor 21 can be representatively one or more dry batteries such as alkaline dry batteries of size AAAA, AAA, AA, C and D, dry manganese batteries of size AAAA, AAA, AA, C and D , alkaline battery with rectangular shape (9 volts), lithium batteries and lithium button batteries that can be used individually or in combination.

The fan 20 for use in the present invention may be a centrifugal fan preferably having a size as set forth below.

The centrifugal fan preferably has a diameter D of 30 mm to 60 mm. If it has a smaller diameter, then its rotation will not produce a sufficient centrifugal force, which requires more energy to make it rotate faster and energy efficiency deteriorates.

This also reduces the volume of the internal space it occupies, which in turn reduces the engine's chances

21. Conversely, making the fan have a D larger than 60 mm will cause the device to be larger and that its portability is poor.

The centrifugal fan preferably has a ratio: D / d of external diameter D with respect to internal diameter d which is 1.05 to 1.6. If it is less than 1.05, then a reduction in the width of a fan blade will not produce enough wind. Conversely, if it exceeds 1.6, then the rotation resistance received by the fan blade will become excessive, again deteriorating its energy efficiency.

The centrifugal fan preferably has an effective blade height h ranging from 2 mm to 10 mm. If it is less than 2 mm in height, the blade will not have enough surface area to produce adequate wind. Conversely, a height of more than 10 mm will not only make the fan inadequate to make the device thin but also a resulting increase in resistance to rotation will reduce its energy efficiency.

If the motor is placed in any place other than in the common internal space in which the centrifugal fan is placed, there will be no bad influence on the wind inlet, but then the apparatus is required to have a thickness that at least is sum of the fan and motor. This has been the path taken by the prior art, however, it is not possible to manufacture such an apparatus as small in thickness as in size as in this case.

If the motor housing (that is, the recess 53 in Figure 2) in which the motor 21 is received occupies more than 60% of the internal space destined to receive the centrifugal fan, then the compensation space will be insufficient for the fan develop sufficient air flow and for it to function effectively.

Therefore, the motor housing (that is, the recess 53 in Figure 2) with the motor 21 housed must be sized to occupy a volume within 60% of the internal space for the centrifugal fan to make the apparatus thin and small in size as a whole while it works effectively to spread a chemical.

This proportion, 60%, of space occupation of the motor housing (ie, recess 53 in Figure 2) should preferably be approximated.

Referring to Figures 7, 8 and 9, an apparatus housing body 101 is shown which has a chemical receptacle (chemical cartridge) 102, a fan 103 and a motor 104 housed therein whereby when the fan 103 rotates by means of the engine 104, air is sucked through the air inlet openings 105 into the chemical receptacle 102 and strikes the chemical receptacle 102 which has a body impregnated with chemical impregnated with a product chemical that is an insect pest control component). Air is then discharged into the same chemical from the body impregnated with chemical in the chemical receptacle 102 through a first and second air discharge opening 106 and 107 to the outside of the housing body 101.

When the apparatus is used with the housing body 101 placed and carried by the user, air containing the insect or chemical pest control component is discharged both through the first air discharge opening 106 upwards and to through the second air discharge opening 107 down.

The first and second air discharge openings 106 and 107 are each in the form of an inclined hole having a radial length and with an inlet 110 that is inside and opens towards the fan 103 and an outlet 111 that is It is located outside and opens on an outer face 101a of the housing body 101. In each of the first and second air discharge openings 106 and 107, the external outlet 111 is defined with its water outlet side edges upstream and downstream 111a and 111b while the internal inlet 110 is defined with its upstream and downstream side entry hole edges 110a and 110b. In each of the first and second air discharge openings 106 and 107, an upstream side guiding face 112 connects the upstream side inlet opening edge 110a at the internal inlet 110 and the outgoing side outlet opening edge upwardly 111a to each other while a downstream side guide face 113 connects the downstream side entry hole edge 110b and the downstream side outlet hole edge 111b to each other.

In each of the first and second air discharge openings 106 and 107, the upstream side guide face 112 is inclined so that the upstream side outlet opening edge 111a is downstream of the inlet opening edge upstream side 110a, preferably the arcuate guide face 112.

In each of the first and second air discharge openings 106 and 107, the downstream side guiding face 113 is inclined so that the downstream side outlet opening edge 111b is downstream of the inlet opening edge downstream side 110b, preferably the arcuate guide face 113.

The internal upstream side orifice edge 110a in the first air discharge opening 106 (for example, the upstream side air discharge opening) and the internal downstream side orifice edge 110b in the second air discharge opening 107 (for example, the downstream side air discharge opening) are preferably close to, and more preferably also act as, the downstream side inlet opening edge 110b in the second air discharge opening 107 and the edge of upstream side inlet opening 110a in the first air discharge opening 106, respectively.

Here, the terms "upstream" and "downstream" are used in relation to the direction in which the fan 103 rotates.

In addition, the term "inclined" is used for the state of being inclined in a radial direction.

In other words, the first and second air discharge openings 106 and 107 are each in the form of an inclined hole in a direction of rotation of the fan.

With the configuration described above, the rotation of the fan 103 causes forced air to escape through the first and second air discharge openings 106 and 107 as indicated by the arrows a and b.

Therefore, when the apparatus is used with the housing body 101 attached to the waist of a user, air containing an insect pest control component is allowed to be forced into its head and feet. Therefore, since the insect pest control component is allowed to reach the head and feet quickly, it is possible to protect the user from harmful insects immediately after starting to use the apparatus.

The specific configurations of device components are mentioned below.

The apparatus housing body 101 comprises a base element 120 and a cover element 121 removably attached thereto and is provided with a fan, a chemical and a chamber that houses the motor 122, 123 and 124.

The chamber that houses the fan 122 is round, in which a fan 103 is rotatably mounted. The chamber housing the fan 122 has a round peripheral face 122a in which the first and second air discharge openings 106 and 107, or their respective internal inlets 110, are opened.

In communication with the chamber that houses the fan 122, the chamber that houses the chemical 123 opposes and is defined with the cover element 121, the cover element 121 being formed with the air inlet openings 105.

The chamber that houses the motor 124 is formed in the base element 120 opening in its rear face 120a and is separated from the chamber that houses the fan 122 by a wall of the base element 120, through which the axis of output 104a of a motor 104 entering the chamber housing the fan 122 in which it is coupled with the fan 103.

In the base element 120 there is also a section that houses the battery 126 that is formed so that it does not open towards the chamber that houses the fan 122 and also does not overlap with the chamber that houses the motor 124 in the direction of its thicknesses The section that houses the battery 126 is formed in the base element 120 as an open recess towards its rear face 120a and is continuous in relation to the space with the chamber that houses the motor 124.

In this section that houses the battery 126, normally in two compartments thereof arranged as shown along the chamber housing the engine 124, two battery cells 127 are accepted, respectively.

With this battery or these battery cells 127, the engine 104 is energized and driven.

With the housing body 101 constructed as mentioned above, its thickness H can be minimized since the battery 127 and the engine 104 can no longer overlap in their thickness direction.

In addition, the chamber that houses the motor 124 and the section that houses the battery (recesses or compartments) that open on the rear face 120a of the base element 120 may be with its cap or plugs for closing.

The housing body 101 is also provided in its base element 120 with a suspension clip 128 and a suspension hole 129.

The suspension clip 128 as shown in Fig. 7 allows the housing body 101 to be hung on a suspension tool 130 which can in turn be attached to or attached to a user's belt or the like in the use of the apparatus.

The suspension utensil 130 as shown in Figure 10 has a hook 131 at one of its ends that can be attached to the suspension clip 128 to engage the housing body 101 in the suspension utensil 130, which has its other end the hook 132 that can fit into the hole 129.

With the hook 132 fitted in the hole 129 as shown in Figure 7, therefore, the utensil 130 when oriented so that it rests as indicated by the imaginary line with the hook 131 placed in contact with a support plane such as a table can also be used to support the housing body 101, specifically the apparatus placed thereon.

Of course, the apparatus can also be used with the rear face 120a of the base element 120 placed on such a support surface.

The chemical receptacle 102 as shown in Fig. 11 comprises a round disk-shaped receptacle 140 with one of its sides open and has a disk-shaped body impregnated with chemical 141 loaded in this round receptacle 140 and a Round lid 142 fitted to the last. In this case, the round receptacle 140 and the round lid 142 are formed with air passages 140a, air passages 142a, respectively.

The chemical impregnated body 141 is a chemical carrier in the form of a thin or sheet-like disk impregnated with a chemical.

The round receptacle 140 is placed on the annular reentrant 143 formed on a front face 120b of the base element 120 so that it fits with and carries it.

As mentioned earlier, the chemical receptacle 102 which uses a body integrated with chemical 141 in the form of a sheet-type carrier impregnated with an insect pest control component is thin and can make the carcass body of apparatus 101 is of small thickness H.

Mention is made below of additional details of the first and second air discharge openings 106 and 107.

Referring to Fig. 8, the fan 103 has its outer peripheral face 103a that is preferably separated from the upstream side entrance hole edge 110a at a distance A ranging between 0.1 mm and 5 mm.

The fan 103 has its center 103b which is preferably separated from the edge of the upstream side entrance hole 110a at a distance R having the ratio: r = 1.05 XRX ∼ 2.5 XR where r is the distance between the center 103b of fan 103 and the upstream side outlet edge 111a.

This converges the wind flows produced by the rotation of the fan 103 so that they effectively converge in the first and second air discharge openings 106 (through these flow paths) and 107, thereby causing the air containing the Insect pest control component is forcedly discharged through it.

Namely, although it is desirable on the one hand that the distance A approaches A = 0 infinitely, on the other hand if A <0.1 mm then it becomes difficult to control the precision of the elements of which the apparatus is composed. Then, an inaccuracy will produce an interference between the fan 103 and the upstream side entry orifice edge, which can be avoided only at a significant additional cost then required to achieve due accuracy.

Conversely, if A> 5 mm, the fan wind 103 will then tend to drive less into the first and second air discharge openings 106 and 107 and to pass rather around the distance zones A and circulate almost in of the chamber that houses the fan 122. Then, wind force will be lost there with a consequent loss of diffusion efficiency.

In addition, if r <1.05 x R, then the width of the first and second air discharge openings 106 and 107 will become so small that the wind of the fan 103 as it passes through them experiences a loss of pressure.

Conversely, if r> 2.5 x R, then the width of the first and second air discharge openings 106 and 107 will become so large that the fan wind 103 suddenly spreads there, again losing its pressure with a consequent loss of diffusion efficiency.

In this case, the expression "width of the first and second air discharge openings 106 and 107" is used with the meaning of the radial distance between the internal inlet 110 and the external outlet 111.

Although the first and second air discharge openings 106 and 107 are normally constructed as mentioned above to present an identical air resistance to discharge an identical air flow through it so that an identical amount of the control component can be emitted From insect pests to both the head and the feet of the user, it may be desirable depending on a place of use to emit more of it to one of these areas than to the other.

Then, the air resistance of an opening selected from the first and second air discharge openings 106 and 107 can be made lower than that of the other to make the air carry more of the insect pest control component to be emitted through of the selected air discharge opening to the outside air. Alternatively, a third air discharge opening may additionally be formed in the base element 120 through which air is made that contains the insect pest control component up or down.

For example, in a modification in this case as shown in Figure 12, a first, a second and a third air discharge opening 106, 107 and 108 can be formed angularly separated at an angle of 120 ° in a vertical plane so that air is emitted through the first, second and third air discharge openings 106, 107 and 108 upwards, downwards and obliquely upwards as indicated by the arrows a, b and c, respectively.

This modification therefore allows the component against insect pests to be emitted higher.

If the apparatus is designed to cause the insect pest control component to be emitted further down, the third outlet opening 108 may be arranged and configured such that it discharges air obliquely downwards. For example, the apparatus may adopt a vertical position opposite to that shown in Figure 12.

Although it is only shown above that the first and second air discharge openings 106 and 107 or the first, second and third air discharge openings 106, 107 and 108 are provided, the apparatus especially when designed for use placed in the The waist may be formed with an auxiliary air discharge opening or openings to direct air laterally therefrom when the insect pest control component may become deficient so that air is emitted in all directions including up and down.

For example, auxiliary air discharge openings 109 oriented laterally to the right and left sides may be formed in a second modification in this case as shown in Figure 13.

An auxiliary air discharge opening 109 of this type is substantially identical but of greater air resistance than the first and second air discharge openings 106 and 107 mentioned above. For example, it is less open in the direction of fan rotation and is of a smaller amount of discharged air and less energetic than the first and second air discharge openings 106 and 107.

Thus, the sizes in the rotation of the fan between the upstream side entrance hole edge 110a and the downstream side entrance hole edge 110b and between the upstream side outlet hole edge 111a and the orifice edge of downstream side outlet 111b in the auxiliary air discharge opening 109 are smaller than in the first and second air discharge openings 106 and 107.

Since this allows air that contains the insect pest control component to be discharged laterally to the right and left sides as indicated by the arrows dye, the insect pest control component can be emitted laterally with respect to the waist of the user, as well as towards the head and feet of the user.

One or two such auxiliary air discharge openings 109 may be provided only on one or both of the right and left sides of the user's waist.

Indeed, it is not necessary that there be any limitations imposed on the number of secondary air discharge openings as mentioned above.

The total number of air discharge openings is preferably a maximum of six, including two main air discharge openings on the upstream and downstream sides (first and 106 and 107 air discharge openings) or three air discharge openings main air on three sides (first, second and third air discharge openings 106, 107 and 108) and one or more auxiliary air discharge openings 109. That will be sufficient to cover insect pest control effects in lateral directions and more than it would simply weaken the air power up and down.

In order to prevent the entry of contaminants through the first and second air discharge openings and third 106, 107, 108 and auxiliary air discharge openings 109, a plurality of current plates can be provided for these air discharge openings , which are preferably oriented horizontally parallel to the wind flows and separated from each other by a distance of 1 to mm.

Each of the current plates of this type has a preferably rectangular, elliptical shape or in the form of a drop of water or any other that does not prevent wind flows.

The chemical for use in the present invention may be an acaricide, parasite or pest repellent, insecticide, or parasite growth retardant or suction inhibitor, and must be volatile.

Such chemicals, if used to kill insects, may be a variety of volatile insecticides known so far, of which pyrethroid, carbamate, organophosphorus, etc. chemicals may be listed, of which pyrethroid chemicals may already be preferably used. They generally have high security.

In addition, specific chemicals of this type such as metroflutrin, transflutrin, empentrine, teraletrin and proflutrin can be used which are highly active and in a small amount are effective as they can make the chemical carrier thin and small.

The sheet-like carrier used impregnated with a chemical in the present invention is manufactured in a representative manner of a porous paper, fabric, net material or woven or non-woven textile material. Taking into account its stability when placed, it is desirable that the body impregnated with chemical for its use is firmly held by a receptacle and its covering part or lid, for example, an outer peripheral part of the body impregnated with chemical type sheet with a resin or similar. The receptacle and lid may be composed of a material such as poly (ethylene terephthalate), polypropylene, polyethylene, polyacetal, nylon, acrylic material, ABS, paper, AS or metal. In addition, considering its portability, it is desirable that the carrier is a thin sheet having a thickness of 2 to 5 mm and an area of 700 to

2

3,000 mm

Especially suitable is the non-woven textile material, preferably a "metsuke" (mass per unit area) of

2 22

10 g / m and more preferably 20 to 50 g / m. If it exceeds 100 g / m, then the body impregnated with chemical will have an air resistance that is too large for the wind to pass through the fan and diffuse the chemical gently. Conversely, if it is less than 10 g / m2, the amount of the chemical that can be retained in the chemical carrier will be too small and soon scarce to justify its manufacture.

The fan can be a centrifugal fan such as a Sirocco fan, radial fan or turbo fan.

The fan should be rotated at a rotation speed of preferably 500 to 4,000 rpm and more preferably 700 to 3,000 rpm.

The centrifugal fan should have a diameter preferably of 20 to 100 mm and preferably 30 to 60 mm. It should have a height preferably from 2 to 50 mm and more preferably from 5 to 20 mm.

The fan, especially a Sirocco fan or radial fan, should preferably have a number of blades from 10 to 50.

The power supply for driving the fan can be representatively one or more of dry batteries such as alkaline dry batteries of size AAAA, AAA, AA, C and D, dried manganese batteries of size AAAA, AAA, AA, C and D, rectangular alkaline battery (9 volts), lithium batteries and lithium button batteries that can be used individually or in combination. A plurality of such dry batteries connected in series can be used

or in parallel. A secondary battery preferably equipped with an AC adapter can also be used to recharge using a domestic power supply (at 100 volts AC).

The housing body 101 can be attached to the user not only by means of the hanger as shown but also in any way such as by means of a clasp or thereby hanging the apparatus in or a hole formed through which a belt can be passed or belt to join the device in an area of the user's feet, waist or arms.

The housing body 101 can be equipped with a switch for activation and deactivation that energizes the device and also with an LED indicator, neon lamp or liquid crystal type for displaying the device being energized. In addition, the fan itself can be made visible from the outside so that the state of the apparatus being energized by the rotation of the fan can be observed.

It should also be advantageous to fix both the battery and the body impregnated with chemical in the chemical receptacle so that their supplies run out simultaneously. Then, the battery and the chemical receptacle can be mounted in a cartridge so that they can be replaced as a body, thereby improving the convenience of the apparatus in maintenance.

Conversely, if the battery and the chemical-impregnated body are not terminated simultaneously, then it should be desirable to indicate the respective endpoints of the battery and the chemical-impregnated body in the chemical receptacle. displayed individually.

Although the housing body 101 (base element 120) is shown above being its peripheral zone forming the chamber that houses the thicker fan 122 to form the air discharge openings, this is not a limitation.

For example, an area of the housing body 101 that is external to the chamber housing the fan 122 is formed with a plurality of guide blades circumferentially so that interstices between these guide blades form air discharge openings.

A replacement camera or chambers can be provided that house the battery in a zone or lateral areas of the housing body 101 and the base element 120.

Although the above description implies the user mainly as a human being, the term is applicable in this case to a pet such as a dog or cattle such as a cow. In this case, an area from anterior to posterior thereof, from its head to the tail or from its face to the belly and the back of the legs is an area of interest to which the control component of the insect pests

As shown in Figures 14, 15 and 16, a blower type chemical diffusion apparatus according to this embodiment a chemical receptacle (chemical cartridge) 201 and an air blower 202. It further comprises a main housing body 205 having an air intake opening 203 through which air is sucked through the air blower 202 and an air discharge opening 204 through which the air that is entrained therein is emitted the chemical that volatilizes from the chemical receptacle 201; a feed housing body 208 separated from the main housing body 205 and containing a power supply 207 for the air blower 202 in the main housing body 205; and an electric cable 209 connecting between the main housing body 205 and the feeding housing body 208 to energize the air blower 202 in the main housing body 205 from the power source 207 in the feeding housing body 208 .

More specifically, the main housing body 205 is generally in the form of a circular cylinder that is axially short. And, it forms the air inlet opening that opens largely upward while forming the air discharge opening 204 that opens in the form of a plurality of grooves in one of its side faces. It should be noted in this case that the number of such air discharge openings and the size and shape of each air inlet of this type and the outlet openings are not limited to those shown and described.

And, the main housing body 205 has inside it and below it the air blower 202 placed. The air blower 202 comprises a motor 211 and a Sirocco 212 fan as a class of the centrifugal fan in which the motor 211 having its output shaft connected to the fan 212. The Sirocco 212 fan has several inclined blades 213 spaced apart in an equidistant manner. circumferentially, which are rotated by the motor 211 to aspirate air through the air inlet opening 203 at the top of the Sirocco 212 fan to cause the aspirated air to flow centrifugally into the main housing body 205 and that it emanates through the air discharge opening 204 from the side face of the main housing body 205. However, the use in this case of the Sirocco 212 fan which is a kind of the centrifugal fan such as the air blower 202 does not it is a limitation but any other suitable fan can be used such as, for example, a propeller fan having an impeller in the form of a propeller around its axis. When such a propeller fan is used as the blower fan, the main housing body 205 may be formed at its bottom with an air passage opening that serves as an air inlet opening and can use the opening 203 mentioned above as an air discharge opening. And, adjacent to the latter, the chemical receptacle 201 loaded with a volatile chemical can be arranged, as mentioned below, so that the air drawn by the blower fan through the air inlet opening in the bottom part passes through the chemical receptacle 201 in the air discharge opening along the blower fan and with the entrainment therein of the volatile chemical so that it is emitted outside.

The chemical receptacle 201 loaded with the chemical and disposed as shown within the main housing body 205 is fitted with an area of the main housing body 205 defining the air inlet opening 203 at its upper part so that which is located above the air blower 202. As shown in Figure 17, the chemical receptacle 201 is round and of small thickness and comprises an upper and a lower element 214 and 215 that accept a chemical carrier (body impregnated with chemical) between them and fit together. The upper and lower elements 214 and 215 are formed with large openings 217 and large openings 218, respectively, through which air passes to volatilize the chemical contained in the chemical carrier 216.

The volatile chemical with which the chemical carrier is to be impregnated in the chemical receptacle 201 is a chemical that serves as an insecticide, repellent, aromatic agent, deodorant, germicide or fungicide. Such chemicals, if used to kill insects, may be a variety of volatile insecticides known so far, of which pyrethroid, carbamate, organophosphorus, etc. chemicals may be listed, of which pyrethroid chemicals may already be preferably used. They generally have high security. In addition, specific chemicals of this type such as metroflutrin, transflutrin, empentrine, teraletrin and proflutrin can be used which are highly active and in a small amount are effective as they can make the chemical carrier thin and small.

In addition, the chemical receptacle 201 and the chemical carrier 216 are not limited to the types described but may be any suitable for retaining a volatile chemical. For example, the chemical carrier 216 can not only be in the form of a sheet but can also be in the form of a net, grids, a honeycomb honeycomb, a flocculate, a sponge and can be a large number of particles that are impregnated with a chemical. In addition, it is not necessary that the chemical receptacle 201 be one in which a chemical carrier 216 impregnated with a chemical is retained but may be one that is manufactured in itself from a hard sponge or foamed body and is impregnates with a chemical, specifically that retains the chemical itself. A chemical receptacle 201 of this type may be of any suitable form and of any suitable material as desired.

The main housing body 205 is formed on its lower face with an adjustment element 219 for attaching to the same adjustment means 206 which allow the main housing body 205 to be adjusted on an object in which the adjustment element 219 is in this case in the form of a thin and elongated hole that extends in its depth along a full length of the main housing body 205.

Then, the adjustment means 206 that allow the main housing body 205 to be attached to an object are attached to the adjustment element 219 having a thin hole that passes through the main housing body 205. The adjustment means 206 are in this case, in the form of a flexible and elongated strap 221 which, when presenting a buckle at one of its ends, can be placed on a user's wrist. This positioning strap allows the main housing body 205 to be adjusted for the diffusion device of chemical products of the type blower object to the wrist of a user or the like for use.

The adjustment means 206 shown by the positioning strap 221 are not limited to what has been described but may have a length ranging from several centimeters, which allows adjustment around the wrist of a user or the like and 1 or 2 meters suitable for adjustment around a user's waist or any suitable protection object and therefore can be of a length as desired. It can also take a variety of forms including a belt, band and rope. Its material is not limited but it can be any suitable known material such as synthetic resin, leather, fabric, fabric and rubber. It is not necessary that the joining means used for the positioning strap 221 be a buckle 222 as shown, but may take the form of a button, a hook shape, a connection strap form, a hook closure form and clip (for example, “magic tape”) or similar.

In addition, it is not necessary that the adjustment means 206 be limited to a positioning strap 221 as shown, but may take the form of a strap to be placed around one leg, a hook 223 to engage in a belt that is placed in pants or in a pocket as shown in figure 18,

or a shape of a clothespin or a clasp to directly join the clothes.

The power housing body 208 includes the power supply 207 for the air blower 202 in the main housing body 205 and is separated from the main housing body 205. The power supply 207 included in the power housing body 208 it is a battery 224. The power housing body 208 is a box of a size that is the minimum to accept the required battery 224, for example, comprising two dry batteries. The battery 224 other than a dry cell or batteries may be a rechargeable battery. The separation of the feeding housing body 208 from the main housing body 205 allows the feeding housing body 208 to be made larger so that the larger battery 224 and the dry batteries 224 in larger numbers accepted therein can be used . This in turn makes it possible to increase the voltage that can be applied to the main housing body 205 so that it is possible to fine-tune the output power of the air blower 202, for example, the intensity of the driven fan, while doing that the diffusion apparatus of the subject blower type chemicals can be used for a prolonged period of time.

The feed housing body 208 can also be adapted so that it can have adjustment means 206 attached thereto which allow it to be an object. The adjustment means 206 may also, in this case, be a positioning strap 221, a hook 223, or a clamp or a clasp as mentioned above.

The coupling cable 209 extending between the main housing body 205 and the feeding housing body 208 to connect them to each other is an electrical cable to electrically energize the air blower 202 in the main housing body 205 from the battery 224 as the power supply 207 in the feed housing body 208. The connection cable 209 should preferably be manufactured as small in diameter as possible. The connection cable 209 can optionally be provided in its intermediate part or at one of its ends with a collection mechanism to make its length adjustable.

In Fig. 19, the connection cable 209 is also shown provided with adjustment means 206 which allow it to be attached to an object. The adjustment means 206 in this case are a connecting element 225 which can be a hook and loop closure tape (for example, a "magic tape" -registered mark) attached to the connecting cable 209 in its intermediate part and which It presents surface irregularities to allow the element to stick to clothing or the like. The connecting element 225 is, of course, not limited to this particular example but may be a safety pin or clothespin or any other suitable means that may cause the connection cable 209 to adhere to clothing or the like. .

The connection cable 209 may be adapted to allow it to be removed from the main housing body 205 or the feeding housing body 208 or both.

With the connection cable 209 which is made to be detachable from both the main housing body 205 and the feeding housing body 208, as shown in Figure 20, the main housing body 205 can be provided on its side face of a pin 226 protruding therefrom and the feed housing body 208 provided on its side face with a female connection 227 recessed therein. Then, the connection cable 20 can be provided at one of its ends with a female connection 228 and at its other end with a pin 229. This allows the main housing body 205 and the feeding housing body 208 to be used which normally they are connected to each other by means of the connection cable 209 for the use of the apparatus to be used in the state in which they are connected directly to each other depending on particular circumstances of their use.

In an example of the use of the blower-type chemical diffusion apparatus constructed as mentioned above, the main housing body 205 is adjusted to a wrist, leg or waist part of a user's body by means of the positioning strap 221. On the other hand, the feeding carcass body 208 is accepted in a pocket of clothes or pants of the user or is attached to the user's waist by another positioning strap 221. Then, the main carcass body 205 and the power housing body 208 is connected to each other by the connection cable 209 and electrical current is passed to the main housing body 205 from the power housing body 208 via the connection cable 209 to operate the blower of air 202 in the main housing body 205. Then, the air blower 202 in the main housing body 205 draws air through the air openings run of air 203 and causes the aspirated air to pass through the chemical receptacle 201 included in the main housing body 205 and dragging the air into the same chemical that is volatilized from the chemical receptacle 201 to emanate and diffuse laterally to the outside through the air discharge openings.

With a blower type chemical diffusion apparatus which as mentioned above comprises a main housing body 205 whereby the air sucked by an air blower 202 is caused to emanate along with a chemical that volatilizes from a chemical receptacle 201 and entrained therein, a power housing body 208 separated from the main housing body 205 to accommodate a battery 224 as a power source 207 for the air blower 202, and a connection cable 209 to connect the main housing body 205 and the feeding housing body 208 with each other, the main housing body 205 is made of small size and light weight by virtue of the fact that the feeding housing body 208 containing the battery 224 as the power source 207 which is the heaviest component of the apparatus, it is made to be separated from the main housing body 205 and it is allowed that e the main housing body 205 contains only the chemical receptacle 201 and the air blower 202. This allows a user, for example, to adjust the main housing body 205 of the diffusion apparatus of the object-type blower chemicals on your wrist or the like using a positioning strap 221 and store the feeding casing body 208 in a pocket of your clothes and then use the device comfortably without an unpleasant sensation by the size and weight of the appliance.

In addition, since the main housing body 205 and the feeding housing body 208 which are separated from each other are used in the state in which they are connected to each other by means of the connecting cable 209, although it happens that either the housing body main 205 or the power housing body 208 in use falls off when separated from the body of the user in which they are placed, the connecting cable 209 that couples them together prevents them from being lost together.

In addition, making the connection cable 209 can be removed from the main housing body 205 and the supply housing 208 allows the connection cable 209 to use the device after adjusting either the main housing body 205 or the body of feeding housing 208 on the user's body to be connected thereto, thereby facilitating its fixation on the user's body.

In addition, providing the main housing body 205, the feeding housing body 208, the connecting cable 209 or each of two or all of them of adjustment means 206, for example, a positioning strap 221, a hook 223, a clamp or a clasp, which allows them to fit on any support object as desired, allows the blower-type chemical diffusion apparatus to be easily adjusted on any desired part of the user's body or any other object of support.

Although it is shown that the battery 224 contained as a power source 207 in the power housing body 208 comprises a dry cell or batteries, it may be a solar cell or batteries. If a solar cell or battery is used as the power source 207 or the battery 224, the diffusion apparatus of the subject blower type chemicals can be used as shown in Figure 21 after pasting the feed housing body 208 onto the brim of a hat worn by the user or a shoulder or the like of the user while adjusting the main housing body 205 on the wrist of a user by means of the positioning strap 221.

In addition, the diffusion apparatus of the object blower type chemicals can be used not only by a human being. For example, it can be used on a pet such as a dog. In this case, as shown in Figure 22, the main carcass body 205 can be fitted to a collar 231 of the pet by means of the adjustment means 206 such as a hook and the feed carcass body 208 fit over a doll or similar of its owner. Then, a connection cable 209 to extend between the main housing body 205 and the feeding housing body 208 can be placed together with a strap 232 to extend between the collar 231 of the pet and the hand of a user to form a belt with cable incorporated for use in a pet.

Furthermore, although in the embodiments described above, the adjustment means 206 are necessarily attached to the main housing body 205, this is not a limitation. The adjustment means 206 described can be attached to each of the main housing body 205, the feeding housing body 208 and the connecting cable 209 or one or each of two of them. It is also possible to provide a diffusion apparatus of object blower chemicals that omits the adjustment means 206.

In addition, although in the embodiments described above, the main housing body 205 is shown as having the chemical receptacle 201 disposed adjacent to the air inlet openings 203, the chemical receptacle 201 may be disposed adjacent to the air discharge openings 204 when equipped with suitable mounting means therefor. In addition, it is possible to provide a chemical receptacle 201 for each of the air discharge and air inlet openings 203 and 204. It is also possible to dispose a chemical receptacle 201 on an outer or inner peripheral side of the Sirocco 212 fan and then integrating the chemical receptacle 201 with the air blower 202, or presenting the Sirocco 212 fan in the air blower 202 supporting a chemical and making it removable, or joining or arranging a chemical receptacle 201 in form of a porous sheet in the front of a large number of blades 213 in the Sirocco 212 fan and make it can be removed.

Referring to Figure 25, a chemical cartridge of the present invention will be described, as an example of its use, applied to a blower type chemical diffusion apparatus using a chemical cartridge to diffuse a chemical into the atmosphere.

As shown in Figure 25, a main housing body 301 is provided with an air blower 302 and has a chemical cartridge 303 removably attached thereto in which a fan 304 of the air blower 302 is made rotate through an engine 305 to allow air to pass through the chemical cartridge 303.

The main housing body 301 includes a base element 310 and a cover element 311, is formed with a blower mounting section 312 and a battery acceptance section 313 and has an air inlet section 314 and a section of air discharge 315.

The air blower 302 has a fan 304 and a motor 305 mounted in a housing 306 provided in the blower mounting section 312. The housing 306 has an air inlet opening 306a that communicates with the air inlet section 314 and also has an air discharge opening (not shown) that communicates with the air discharge section 315.

A battery 307 shown as comprising two dry batteries is attached in the battery acceptance section 313.

The cover element 311 is connected to the main housing body 310 so that it can be opened and closed, whereby opening the cover element 311 allows the chemical cartridge 303 and the battery 307 to be removed and fitted.

The chemical cartridge 303 is adapted to accept a chemical carrier or impregnated body 320 in the form of an air-permeable or porous sheet that absorbs liquid impregnated with a chemical, and has a retainer or retention receptacle 321 for retaining the body impregnated with chemical 320.

In other words, since the body impregnated with chemical 320, which is in the form of a sheet of this type, which absorbs so much liquid and is so weak in stiffness that it cannot be sustained and if it is held directly with one hand , a chemical therein may adhere to the hand, it is held along a part thereof with the retention receptacle 321 to cause air to pass through other parts thereof.

Thus configured and arranged, the chemical cartridge 303 can be made thin because the chemical carrier or impregnated body 320 is in this case thin and the retention receptacle 321 can be made thin.

Therefore, the use of such a chemical cartridge 303 allows a blower-type chemical diffusion apparatus to be thinned as described.

The holding receptacle 321 includes a clamping section 321a that holds the upper and lower faces of the body impregnated with chemical 320 from above and below and an air flow section 321b through which air flows.

Between the clamping section 321a and the chemical-impregnated body 320 there is formed a space 321c, which opens to the outside through a ventilation section 321d formed in the clamping section 321a so that air can be passed through the 321c space.

Preferably, the clamping section 321a is formed with a recess in which it is in contact with the lower face of the body impregnated with chemical 320 and the space 321c is formed between this recess and the lower face of the body impregnated with chemical 320. And, the clamping section 321a in which it is in contact with the upper face of the body impregnated with chemical 320 is formed with ventilation holes constituting the ventilation section 321d and through which the space 321c (recess) opens To the exterior.

Thus constructed, the holding receptacle 321 can retain the body impregnated with chemical 320 in the form of a sheet while maintaining its shape and can be held with one hand without fear that the chemical can contaminate the hand.

In addition, although the chemical in an area of the body impregnated with chemical 320 in which it is held by the clamping section 321a is not volatilized with an air flow since air flows are prevented there, the chemical is still it is volatilizing in space 321c and from the latter to the outside through the air flow section 321b and, therefore, is allowed to emanate and diffuse into the surrounding atmosphere.

Although specific mention is made below of the holding receptacle 321 as to its possible shape, it should be understood that this is by way of example only and does not limit it.

The retention receptacle 321 as shown in Figures 25 to 31 comprises a receptacle body element 330 and a receptacle cover element 340 by and between which the body impregnated with chemical 320 is held and retained.

The receptacle body member 330 has a central support section 331, a peripheral support section 332 separated from and around the central support section 330 and a plurality of intermediate support sections 333 connecting the peripheral support section 332 to the central support section 331 in which a space defined with the central support section 331, the peripheral support section 332 and neighboring intermediate support sections 333 connected to each other by the peripheral support section 332 is open constituting a flow section of air 334.

The central support section 331 has its upper face 331a formed with a recess 335 in which it is in contact with the lower face of the body impregnated with chemical 320 and which forms the space 321c in another place where it is opposite the face lower body impregnated with chemical 320.

The peripheral support sections 332 have their upper face 332a formed with an annular recess 336 in which they are in contact with the lower face of the body impregnated with chemical 320 and which forms the space 321c in another place where it is opposite to the lower body face impregnated with chemical 320.

The intermediate support sections 333 have their upper faces 333a formed with recesses 337 in which they are in contact with the lower face of the body impregnated with chemical 320, recesses that communicate between the recess 335 and the annular recess 336, forming the upper faces 333a the space 321c in another place where they are opposite the lower face of the body impregnated with chemical 320.

The receptacle cover element 340 has a central clamping section 341, a plurality of separate peripheral clamping sections 342 and around the central clamping section 341 and a plurality of intermediate clamping sections 343 connecting the peripheral clamping section 342 to the central clamping section 341 in which a space defined with the central clamping section 341, the peripheral clamping section 342 and neighboring intermediate clamping sections 343 connected to each other by the peripheral section 342 is open constituting a flow section of air 344.

The central clamping section 341 is identical in size to the central support section 331 and has a ventilation hole 345 opposite the recess 335.

The peripheral clamping section 342 is identical in size to the peripheral support section 332 and has a vent hole 346 opposite the annular recess 336.

The intermediate clamping sections 343 are identical in shape and size to the intermediate supporting sections 333, and the air flow sections 344 are opposite to the air flow sections 334 so that air flows smoothly through both air flow sections 334 and 344. The intermediate clamping sections 343 are formed with ventilation holes 347 so that they are opposite to recesses 337, respectively.

The receptacle body element 330 and the receptacle cover element 340 are detachably joined together.

In the embodiment shown, the peripheral support section 332 has its raised outer edge from its upper face 332a to form a raised flange 332b in the form of a ring in which the body impregnated with chemical 320 and then the element of receptacle cover 340.

As an alternative to this joint design, the cover element 340 can be formed with such a raised flange that can be adjusted over the outer edge or flange of the peripheral support section 332 to join the cover element 340 to the body element of receptacle 330. Still alternatively, the receptacle body and cover elements 330 and 340 can be provided with a pin and a hole that can coincide with each other to join these elements together.

Furthermore, although in this embodiment the intermediate support and clamping sections 333 and 343 are each shown as comprising a plurality of radially extending subsections, not only can such subsections be, if adopted, in the form of a grid. but it can also comprise each section 333, 343, for example, a porous plate or the like.

Thus constructed and arranged as mentioned above, the retention receptacle 321 acts to hold and support the body impregnated with chemical 320 supporting and holding a central area thereof with and between the central support and clamping sections 331 and 341, a peripheral zone thereof with and between peripheral support and clamping sections 332 and 342 and an intermediate zone thereof with and between intermediate support and clamping sections 333 and 343.

This allows air to flow through the air flow sections 334 and 344 to pass through the body impregnated with chemical 320.

Air is also allowed to flow through the space 321c formed between recesses 335, 336 and 337 and the lower face of the body impregnated with chemical 320.

Thus constructed and adapted as mentioned above, the chemical cartridge 303 is loaded into the main housing body 301 and in this embodiment is attached to the upper face of the housing 306.

And, the rotation of the fan 304 causes air to flow through the body impregnated with chemical 320 and to emanate and diffuse chemical into the surrounding atmosphere.

In addition, chemical is allowed to volatilize in an area of the body impregnated with chemical 320 which is held between each pair of support and clamping sections in space 321c and then it is dragged into the air flowing from the orifices of ventilation whereby air is emitted that presents chemical entrained therein into the atmosphere as fan 304 is rotated.

Furthermore, with the support sections 331, 332 and 333 formed on their upper faces with the recesses 335, 336 and 337 to form the space 321c and with the clamping sections 341, 342 and 343 formed with the ventilation holes 345, 346 and 347 to make the space 321c open to the outside, it is possible to use the recesses 335, 336 and 337 to present a carrier of used chemical 320 re-impregnated with a chemical.

For example, a chemical cartridge used (with a chemical-depleted chemical carrier) 303 is removed from the main housing body 301 and liquid chemical is poured into the ventilation holes 345, 346 and 347 to supply and store the recesses 335, 336 and 337 with them.

The liquid chemical stored in the recesses 335, 336 and 337 is allowed to be impregnated in the chemical carrier 320 throughout the body to form an unused chemical cartridge impregnated with the chemical.

Since liquid chemical charged in the recess 335 is impregnated in a central area of the chemical carrier 320, liquid chemical charged in the annular recess 336 is impregnated in a peripheral area of the chemical carrier 320 and liquid chemical is impregnated loaded into recess 337 for communication in an intermediate zone of the chemical carrier 320, the chemical carrier 320 is impregnated with chemical rapidly throughout the body.

In this case, the ways in which a liquid chemical is supplied can visually check its supply quantity using a calibrated drip pipette, a dosing vial, a measuring container or a container with a measuring cup, or a nozzle.

Furthermore, since when supplying a chemical it is convenient that its delivery time can be visually checked, it is desirable to use a body impregnated with chemical 320 that can be of known type with an indicator that displays its depletion time.

Although in the embodiment described above, the receptacle body element 330 is shown as having three support sections 331, 332 and 333 formed on its upper faces 331a, 332a and 333a with recesses 335, 336 and 337 and the element of receptacle cover 340 as having three clamping sections 341, 342 and 343 formed with ventilation holes 345, 346 and 347, which do not limit the same and have only a couple of opposite support and clamping sections formed with a recess and a ventilation hole, respectively, or two pairs of opposing support and clamping sections formed with recesses and ventilation holes, respectively.

Namely, there must be at least one pair of opposing support and clamping sections formed with a recess and a vent hole, respectively.

For example, in a modification as shown in Figures 32 and 33, the peripheral support section 332 in the receptacle body member 330 may have its inner edge folded inwardly to form an annular recess 336 whose cross section is in form of a V, providing a space 321c between itself and the lower face of the body impregnated with chemical 320.

On the other hand, parts of the peripheral clamping section 342 in the receptacle cover element 340, for example parts in which it continues to the intermediate clamping sections, can be folded inward to form recesses 348.

These recesses 348 are formed to provide ventilation sections 321d between themselves and the raised flange 332b of the receptacle body member 330.

Although in this case the space 321c is formed below the body impregnated with chemical 320, it can alternatively be formed above or both above and below the body impregnated with chemical 320.

Not only is a chemical cartridge 303 according to the present invention used with a blower type chemical diffusion apparatus as described above, but it can also be attached directly to the fan in an air blower and can be otherwise integrated into the fan. In addition, it can be arranged either in an air inlet or an outlet side. Even more, it can be attached to the blow outlet opening of an air conditioner.

The chemical that can be impregnated in a chemical carrier or impregnated body of the present invention can be an insect pest control agent (insecticide, repellent, growth inhibitor, acaricide, insect control essential oil or the like), aromatic agent, aromatic deodorant, deodorant, fungicide, disinfectant or parasite repellent, and especially such a chemical that is volatile at a common temperature or airflow conditions.

Such chemicals, if used to kill insects, may be a variety of volatile insecticides known so far, of which pyrethroid, carbamate, organophosphorus, etc. chemicals may be listed, of which pyrethroid chemicals may already be preferably used. They generally have high security.

In addition, specific chemicals of this type such as metroflutrin, transflutrin, empentrine, teraletrin and proflutrin can be used which are highly active and in a small amount are effective as they can make the chemical carrier thin and small.

Model materials from which the chemical carrier of the present invention can be formed include natural and chemical fibers, non-woven textile material (from natural, chemical and carbon fibers), resin network (polyester, polypropylene, poly (chloride of vinyl)), fabric (woven or knitted), paper thread (paste, linter, synthetic paper). The material can be a formed body such as in the form of a sheet, net, honeycomb honeycomb, drain board or grid, a deformable body to maintain its shape when confined, or is a flocculate or a sponge.

Of these materials, a sheet-like material of nonwoven fabric that is distinguished by its air permeability and chemical retention is preferred.

Referring to Figure 34, a chemical cartridge will be described in another form of the present invention, as an example of its use, applied to a blower type chemical diffusion apparatus using a chemical cartridge to diffuse a product. Chemical into the atmosphere.

As shown in Figure 34, a main housing body 401 is provided with an air blower 402 and has a chemical cartridge 403 removably attached thereto in which a fan 404 of the air blower 402 is made rotate through an engine 405 to allow air to pass through the chemical cartridge 403.

The main housing body 401 includes a base element 410 and a cover element 411, is formed with a blower mounting section 412 and a battery acceptance section 413 and has an air inlet section 414 and a section of air discharge 415.

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 an air inlet opening 406a that communicates with the air inlet section 414 and also has an air discharge opening (not shown) that communicates with the air discharge section 415.

A battery 407 shown as comprising two dry batteries is attached in the battery acceptance section 413.

The cover element 411 is thus connected to the main housing body 410 so that it can be opened and closed, whereby opening the cover element 411 allows the chemical cartridge 403 and the battery 407 to be removed and fitted.

The chemical cartridge 403 is adapted to accept a chemical carrier or impregnated body 420 in the form of an air-permeable or porous sheet that absorbs liquid impregnated with a chemical, and has a retainer or retention receptacle 421 to retain the body impregnated with chemical 420.

In other words, since the body impregnated with chemical 420, which is in the form of such a sheet, that absorbs so much liquid and is so weak in stiffness that it cannot be sustained and if it is held directly with one hand , a chemical therein may adhere to the hand, is held along a part thereof with the retention receptacle 421 to cause air to pass through other parts thereof.

The retention receptacle 421 includes a clamping section 421a that holds the chemical impregnated body 420 and an air flow section 421b through which air flows. The clamping section 421a has a liquid accumulation recess 421c in its center, specifically in the center of the retention receptacle

421

The housing 406 is formed with a recess 406b in which the retention receptacle 421 fits and sits firmly. Then, the rotation of the fan 404 causes air to flow through the body impregnated with chemical 420 and to emanate and diffuse chemical product with the same towards the surrounding atmosphere.

Thus constructed as mentioned above, the chemical cartridge 403 after use, specifically with chemical carrier 420 depleted of chemical, is removed from the main housing body 401, and liquid chemical is supplied in the accumulation recess of liquid 421c and accumulates there.

The accumulated liquid chemical in the liquid accumulation recess 421c is allowed to permeate the chemical carrier 420 progressively therewith through the entire body to form an unused chemical cartridge impregnated with the chemical.

Therefore, this is a chemical cartridge that can be used repeatedly by re-supplying chemical every time it is consumed.

Since the chemical cartridge 403 sits opposite the fan 404 with its center opposite the center of the fan 404, the center of the retention receptacle 421 is opposite that of the fan 404.

Therefore, provided that it is located in the center of the retention receptacle 421, the liquid accumulation recess 421c in the use of the apparatus is in an area where the airflows by the rotation of the fan 404 are scarce, and few prevents, allowing almost all of them to pass through the body impregnated with chemical 420 and so that it is consumed effectively to diffuse chemical into the atmosphere with little loss of the air blower outlet 402.

Namely, the liquid accumulation recess 421c as shown in Figure 34 is positioned to be opposite the center of the fan 404 coupled to the rotation axis 405a of the motor 405 when the air flows from the fan 404 reach the minimum a around it and are not substantially prevented in any way by the presence of the liquid accumulation recess 421c.

In addition, the chemical cartridge 403 can be made thin because the chemical carrier or impregnated body 420 is in this case thin and the retention receptacle 321 can be made thin.

Mentioned below is a specific form of the retention receptacle 421.

The retention receptacle 421 as shown in Figures 34 and 35 comprises a receptacle body element 430 and a receptacle cover element 440 by and between which the body impregnated with chemical 420 is held and retained.

The receptacle body member 430 has a central support section 431, a peripheral support section 432 separated from and around the central support section 430 and a plurality of connection support sections 433 connecting the peripheral support section 432 to the central support section 431 in which a space defined with the central support section 431, the peripheral support section 432 and neighboring connection support sections 433 connected to each other by the peripheral support section 432 is open constituting a section air flow 434.

The central support section 431 has its support face 431a formed with a recess 435.

The receptacle cover element 440 has a central clamping section 441, a plurality of separate peripheral clamping sections 442 and around the central clamping section 441 and a plurality of connecting clamping sections 443 connecting the peripheral clamping section 442 to the central clamping section 441 in which a space defined with the central clamping section 441, the peripheral clamping section 442 and neighboring connection clamping sections 443 connected to each other by the peripheral section 442 is open constituting a section of air flow 444.

The central clamping section 441 is identical in size to the central support section 431 and has a supply opening 445 opposite the recess 435, the supply opening 445 and the recess 435 constituting the liquid accumulation recess 421c.

The peripheral clamping section 442 is identical in size to the peripheral support section 432.

The connection clamp sections 443 are identical in shape and size to the connection support sections 433, and the air flow sections 444 are opposite to the air flow sections 434 so that air flows smoothly through of both air flow sections 434 and 444.

The receptacle body element 430 and the receptacle cover element 440 are detachably joined together.

In the embodiment shown, the peripheral support section 432 has its raised outer edge from its support face 432a to form a raised flange 432b in the form of a ring in which the body impregnated with chemical 420 fits and then fits the receptacle cover element 440.

Alternatively to this joint design, the cover element 440 may be formed with such a raised flange that can be adjusted over the outer edge or flange of the peripheral support section 432 to join the cover element 440 to the body element of receptacle 430. Still alternatively, the receptacle body and the cover elements 430 and 440 can be provided with a pin and a hole that can coincide with each other to join these elements together.

Furthermore, although in this embodiment the connection support and clamping sections 433 and 443 are each shown as comprising a plurality of radially extending subsections, not only that such subsections may be, if adopted, in the form of a grid but can also comprise each section 433, 443, for example, a porous plate or the like.

Thus constructed and arranged as mentioned above, the retention receptacle 421 acts to hold and support the chemical cartridge 420 supporting and holding a central area thereof with and between the central support and clamping sections 431 and 441, an area peripheral thereof with and between peripheral support and clamping sections 432 and 442 and an intermediate zone thereof with and between connection support and clamping sections 433 and 443.

This allows air to flow through the air flow sections 434 and 444 to pass through the body impregnated with chemical 420.

Therefore, a chemical cartridge used (with a chemical carrier depleted of chemical) 403 is removed from the main housing body 401 and liquid chemical is poured into the supply opening 445 to supply and store the recess 435, or the recess 435 and the supply opening 445 therewith.

The liquid chemical stored in the recess 435 is allowed to be impregnated in the chemical carrier 320 throughout the body to form an unused chemical cartridge impregnated with the chemical.

The depth of the liquid accumulation recess 421c can be determined depending on the amount of chemical to be supplied and has no particular limitation. If the lower face of the sheet and the upper face of the recess 435 abut against each other, the depth can then be such that the liquid chemical supplied remains at its surface tension with the sheet body. If the depth is excessive, then part of the liquid may remain without being in contact with the sheet.

Mention is made below of a first modification of the chemical cartridge mentioned above.

As shown in Figures 36 and 37, the central support section 431 of the receptacle body element 430 is made larger than the central fastening section 441 of the receptacle cover element 440 with the recess 435 larger than the central clamping section 441.

The central clamping section of the cover element 440 becomes thicker than the connection section 443 so that it protrudes downward beyond each connection section 443 to press the chemical impregnated body 420 towards the recess 435 therewith .

This helps the chemical stored in the recess 435 permeate the sheet in the body.

If the sheet is placed to be near or in contact with the base of the recess 435 as shown in Figure 37, the depth of the recess 421c is determined depending on the amount of chemical to be supplied and does not need to be much since the chemical as soon as it is supplied will begin to permeate around it.

The above embodiment and its first modification mentioned above are particularly advantageous if the body impregnated with chemical 420 is small. If it is large, it is desirable that a recess of liquid accumulation be formed in the peripheral section also so that chemical can be supplied both in the central and peripheral sections so that it permeates both from the central part to the periphery and from the peripheral to the central.

This is effective for quickly disposing of a permeate of chemical throughout the body of a sheet and therefore advantageous in the manufacture of such products by man.

For example, in a second modification as shown in Figures 38 and 39, in the receptacle body element 431, the central support section 431 is formed with the recess 435 and the peripheral section 432 is formed with a peripheral recess 436 which is, for example, void.

The central clamping section 441 in the cover element 440 is formed with the supply opening 445. Each connecting section 443 extends outwardly to protrude from each peripheral clamping section 442, forming an extension 443a in contact with the raised edge. 432b while providing a gap between the peripheral clamping section 442 and the raised edge 432b to constitute a peripheral supply opening 446.

A peripheral recess 436 thus formed is made to act as a liquid accumulation recess 421c in the peripheral section.

In this second modification, the peripheral clamping section 442 becomes thicker than the central clamping section 441 to press a peripheral edge of the body impregnated with chemical 420 towards the peripheral recess 436 to help the chemical permeate in the body impregnated with chemical 420.

In addition, in a third modification as shown in Figures 40 and 41, the peripheral support section 432 of the receptacle body element 430 is folded down so that a peripheral recess 436 is formed by the folded peripheral support section 432 and the raised edge 432b.

The connection sections 443 of the cover element 440 are also folded down so that the peripheral fastening section 442 is adapted to the bent peripheral support section 432.

This presses a peripheral edge of the body impregnated with chemical 420 against the peripheral support section 432.

Parts of the peripheral clamping section 442 of the cover element 440, for example, where it is connected to the connection sections 443, deform to form teeth 442a there, thereby forming openings between these teeth and the raised edge 432b, respectively , to constitute peripheral supply openings 446.

In addition, in a fourth modification as shown in Figures 42 and 43, the central fastening section 441 of the cover element 440 is formed with a downwardly oriented recess 445a which is in turn formed on its upper face with a plurality of small supply holes 445b whereby the downwardly oriented recess 445a and the supply holes 445b constitute a supply opening 445 and the supply opening 445 and the recess 435 constitute a liquid accumulation recess 421c.

The peripheral clamping section 442 of the cover element 440 comprises an internal vertical subsection 448 and an upper flat subsection 449 defining a downwardly oriented recess 446a in which the upper flat subsection is formed with peripheral supply holes 446b which together with the Downwardly oriented recess 446a constitute a peripheral supply opening 446 and the latter and peripheral recess 436 constitute a liquid accumulation recess 421c in the peripheral section.

In addition, it is possible to improve the surface tension of the liquid chemical with the sheet. For this purpose, the internal base of each of the recesses can be processed by embossing or similar to confer surface irregularities thereto, to create small spaces in the form of a grid, or a plurality of raised edges can be provided to form striations .

As mentioned earlier, the ways in which a liquid chemical is supplied in a liquid accumulation recess 421c can visually check its supply amount using a calibrated drip pipette, a dosing vial, a measuring vessel or a container. with a measuring cup, or a mouthpiece.

In addition, since when supplying a chemical it is convenient that its delivery time can be visually checked, it is desirable to use a body impregnated with chemical 420 that can be of known type with an indicator that displays its depletion time.

Furthermore, it is not only a chemical cartridge 403 according to the present invention used with a blower type chemical diffusion apparatus as described above, but it can also be attached directly to the fan in an air blower and can be integrated in Another mode on the fan. In addition, it can be arranged either in an air inlet or an outlet side. Even more, it can be attached to the blow outlet opening of an air conditioner.

The chemical that can be impregnated in a chemical carrier or impregnated body 420 of the present invention can be an insect pest control agent (insecticide, repellent, growth inhibitor, acaricide, insect control essential oil or the like) , aromatic agent, aromatic deodorant, deodorant, fungicide, disinfectant or parasite repellent, and especially such a chemical that is volatile at a common temperature or air flow conditions.

Such chemicals, if used to kill insects, may be a variety of volatile insecticides known so far, of which pyrethroid, carbamate, organophosphorus, etc. chemicals may be listed, of which pyrethroid chemicals may already be preferably used. They generally have high security.

In addition, specific chemicals of this type such as metroflutrin, transflutrin, empentrine, teraletrin and proflutrin can be used which are highly active and in a small amount are effective as they can make the chemical carrier thin and small.

Model materials from which the chemical carrier of the present invention can be formed include natural and chemical fibers, non-woven textile material (from natural, chemical and carbon fibers), resin network (polyester, polypropylene, poly (chloride of vinyl)), fabric (woven or knitted), paper thread (paste, linter, synthetic paper). The material can be a body formed in the form of a sheet, net, honeycomb honeycomb, drain board or grid, a deformable body to maintain its shape when it is confined, or is a flocculate or a sponge.

Of these materials, a sheet-like material of nonwoven fabric that is distinguished by its air permeability and chemical retention is preferred.

Referring to Figure 44, a chemical cartridge that is not part of the invention will be described, as an example of its use, applied to a blower type chemical diffusion apparatus using a chemical cartridge to diffuse a chemical into the atmosphere

As shown in Figure 44, a main housing body 501 is provided with an air blower 502 and has a chemical cartridge 503 removably attached thereto in which a fan 504 of the air blower 502 is made rotate using a 505 engine to allow air to pass through the 503 chemical cartridge.

The main housing body 501 includes a base element 510 and a cover element 511, is formed with a blower mounting section 512 and a battery acceptance section 513 and has an air inlet section 514 and a section of air discharge 515.

The air blower 502 has a fan 504 and an engine 505 mounted in a housing 506 provided in the blower mounting section 512. The housing 506 has an air inlet opening 506a that communicates with the air inlet section 514 and also has an air discharge opening (not shown) that communicates with the air discharge section 515.

A battery 507 shown as comprising two dry batteries is attached in the battery acceptance section 513.

The cover element 511 is thus connected to the main housing body 510 so that it can be opened and closed, whereby the opening of the cover element 511 allows the chemical cartridge 503 and the battery 507 to be removed and fitted.

The chemical cartridge 503 is adapted to accept a body impregnated with chemical 520 in the form of a sheet and has a retainer or retention receptacle 530 to retain the body impregnated with chemical 520.

That is, since the body impregnated with chemical 520, which is in the form of a sheet of this type, which absorbs so much liquid and is so weak in stiffness that it cannot be sustained and if it is held directly with one hand, A chemical in it can adhere to the hand, it is held along a part of it with the retention receptacle 530 to cause air to pass through other parts thereof.

This allows the chemical cartridge 520 to become thin and easy to handle.

The chemical-impregnated body 520 comprises a carrier 521 in the form of a sheet impregnated with and retaining in it a chemical in a given amount.

The sheet-type carrier 521 of the body impregnated with chemical 520 has a high liquid retention zone 522 that can at the same time be impregnated with and capture a large amount of chemical, which progressively permeates the carrier 521 throughout the body .

Thus constructed and adapted as mentioned above, a chemical cartridge 503 when consumed (when the chemical contained in the carrier 521 of the body impregnated with chemical 520 is depleted or diffuses completely into the surrounding atmosphere and the carrier 521 does not have such a chemical contained therein) allows it to be re-supplied by dripping and thus a large amount of chemical is supplied in the high liquid retention zone 522 to allow the chemical to progressively permeate in the carrier 521 for the entire body until the carrier 521 is fully loaded with the chemical, thereby reproducing an unused chemical cartridge.

Therefore, this is a chemical cartridge that can be used repeatedly by re-supplying chemical every time it is consumed.

In addition, since also in the manufacturing phase, a large amount of chemical can be supplied to the carrier 521 of a chemical impregnated body 520 with a large amount of chemical to allow it to gradually permeate the carrier 521 through the entire body, it is possible to impregnate carrier 521 evenly throughout the entire body with chemical.

Mention is made specifically below of a currently preferred but not exclusive example of the chemical cartridge 503 with reference to Figures 45 and 46.

The carrier 521 of this body impregnated with chemical 520 is in the form of a sheet whose central part is thicker than any other thereof, constituting the high liquid retention zone 522.

The high liquid retention zone 522 is formed in its upper part with a recess 522a to help the chemical to be absorbed when easily supplied inside.

Although the liquid absorption capacity (the magnitude of a quantity of liquid that can be absorbed in an area unit) of the carrier 521 is uniform throughout its area, its central area that has become thin can absorb a large amount of chemical and may constitute the high liquid retention zone 522.

Preferably, however, the carrier 421 can be made to absorb more liquid in its central part than in the other parts, allowing this part (the high liquid retention zone 522) to be impregnated with a maximum amount of chemical.

However, if the high liquid retention zone 522 of the carrier 521 becomes of greater liquid absorbing power than its other zones, this zone can be made of the same thickness as the other zones.

Therefore, the high liquid retention zone 522 of a carrier 521 may indeed be an area in which the amount of liquid that can be absorbed per unit volume is greater than in any other part thereof.

In addition, the high liquid retention zone 522 can have any shape, that is, not only round as mentioned but also rectangular, semicircular or in elevation, depending on its model material used.

The retention receptacle 530 comprises a receptacle body element 540 and a clamping element 550 by and between which the body impregnated with chemical 520 is held and retained.

The receptacle body member 540 has a central support section 541, a peripheral support section 542 and a plurality of connection support sections 543 connecting the peripheral support section 542 to the central support section 541 in which a space defined with the central support section 541, the peripheral support section 542 and neighboring connection support sections 543 connected to each other by the peripheral support section 542 is open constituting an air flow section 544.

The peripheral support section 542 has its raised outer edge from its upper face to form a raised edge 545 in the form of a ring.

The chemical-impregnated body 520 is placed on and supported by the upper faces 541a, 542a and 543a of the central and peripheral and connection support sections 541, 542 and 543.

The clamping element 550 is in the form of a ring that can be adjusted with the raised ring-shaped edge 545 to hold a peripheral part of the body impregnated with chemical 520 by and between the clamping element 50 and the peripheral support section 542 .

The chemical cartridge 503 as shown in Figure 44 is mounted by adjusting with its mounting section 506b of the housing 506 and opposite the fan 504 of the air blower 502 so that the central part 504a of the fan 404 with low flow of Air (specifically, in which the axis of rotation 505a of the motor 505 is coupled thereto) is opposite to the central part (the high liquid retention zone 522) of the carrier 521 of the body impregnated with chemical 520.

Therefore, through the high liquid retention zone 522 there will be much less air flow than anywhere else around it to allow air to flow smoothly through the body impregnated with chemical 520 without being prevented by the area of high liquid retention 522 despite its thickness.

Being placed on the upper face 541a of the central support section 541 of the retention receptacle 540, the high liquid retention zone 522 to which a large amount of chemical is supplied when refilled to increase its weight, is prevents it from falling apart.

In addition, being identical in size or greater than the high liquid retention zone 522, the central support section 541 prevents liquid chemical from escaping downward from the underside of the high liquid retention zone 522 when it is It supplies a large amount of liquid chemical.

The central support section 541 may be in the form of a shallow and serrated disc.

Mention is made below of modifications to this embodiment.

The central support section 541 of the receptacle body element 540 may be smaller than the high liquid retention zone 522. In addition, the connection sections 643 may be only six but also four, three or similar in number.

In a first modification as shown in Figures 47A and 47B, the clamping element 550 may have a central ring 551, a peripheral ring 552 and a plurality of braces 553 connecting the central and peripheral rings 551 and 552 to form openings 554 and so that the central ring 551 can be adjusted with the high liquid retention zone 522 and the peripheral ring 552 is adjusted with the raised ring-shaped edge 545 of the receptacle body member 540.

This allows the central ring 551 to provide an indication of chemical added dropwise and supplied.

In this case, the central support section 541 of the receptacle body element 540 may be in the form of a ring.

Furthermore, in this case, the central ring 551 of the clamping element 550 can butt on the upper face of the high liquid retention area 522 to secure it with the central support section 541.

In addition, the central ring 551 may be of greater height than the high liquid retention zone 522 to prevent the liquid chemical supplied from escaping.

In a second modification as shown in Figures 48A and 48B, the chemical impregnated body 520 may have its high liquid retention zone 522 located closest to the periphery of the carrier 521.

For example, the carrier 521 may have a plurality of high liquid retention areas 522 located circumferentially spaced from each other along a peripheral zone thereof.

In a third and fourth modification as shown in Figures 49 and 50, the high liquid retention zone 522 of the chemical impregnated body 520 is in the form of a narrow band that extends and is diametrically continuous. In this case the liquid chemical retention zone 522 is supplied in this case with liquid chemical coming from the central zone, such as the central ring 551, of the clamping element 550 in the arrangement shown in Figure 49 and from the peripheral zone, such as openings 554 formed between the teeth 552a of the deformed peripheral ring 552 of the clamping element 550 and the raised ring-shaped edge 545 of the peripheral support section 542 of the receptacle body element 540 in the arrangement shown in Figure 50 In additional modifications not shown, a plurality of high liquid retention zones in the form of a band 522 of this type may be formed and arranged in the form of a grid, or one or more of high retention areas may be suitably located. of liquid 522 of this type, as desired.

The high liquid retention zone 522 of the body impregnated with chemical 520 may be formed separately from the carrier 521 and may be disposed above and / or below the carrier 521.

For example, in a fifth modification as shown in Figure 51, a pair of carriers 521 are used to hold a high liquid retention zone 522 therebetween.

In addition, in a further modification not shown, the high liquid retention zone as a separate body fits into the central ring 551 of the clamping element 550 and is thus mounted while the clamping element 550 is attached to the body element of receptacle 40 so that it puts the high liquid retention zone 522 in contact with the carrier 521.

Alternatively, the carrier 521 may be disposed on the high liquid retention zone 522 mounted as a separate body on the central support section 541 of the receptacle body element 540.

Mention is made below of how the high liquid retention zone 522 described above can be specifically implemented.

The high liquid retention zone 522 as a separate body is formed of the same material or a material other than the material from which the carrier 521 is formed, and is integrated with, or is attached to, sewn with, placed on or weld to bearer 521.

Alternatively, a model material is blown by special machining on a portion of the carrier 521 to perform a large "metsuke" so that a high liquid retention zone 522 accumulates.

Model materials from which the carrier 521 of the body impregnated with chemical 520 or the high liquid retention zone 522 as a separate body can be formed include natural and chemical fibers, non-woven textile material (of natural, chemical and carbon fibers) , resin net (polyester, polypropylene, polyvinyl chloride), fabric (woven or knitted), paper thread (paste, linter, synthetic paper). The material can be a formed body such as in the form of a sheet, net, honeycomb honeycomb, drain board, grid or crease, a deformable body to maintain its shape when it is confined, or is a flocculate or a sponge, and also foamed pearls, foamed urethane and charcoal made of wood or bamboo.

Of these materials, a sheet-like material of non-woven textile material that is distinguished by its air permeability and chemical retention is preferred.

The ways in which a liquid chemical is supplied in a high liquid retention zone 522 can visually check its supply quantity using a calibrated drip pipette, a dosing vial, a measuring vessel or a vessel with a measuring vessel , or a mouthpiece.

In addition, since when supplying a chemical it is convenient that its time of new supply can be checked visually, it is desirable to use a body impregnated with chemical 420 that can be of known type with an indicator that displays its depletion time.

The chemical that can be impregnated in the carrier 521 of a body impregnated with chemical 521 for use in the present invention may be an insect pest control agent (insecticide, repellent, growth inhibitor, acaricide, control essential oil of insects or the like), aromatic agent, aromatic deodorant, deodorant, fungicide, disinfectant or parasite repellent, and especially such a chemical that is volatile at a common temperature or airflow conditions.

Such chemicals, if used to kill insects, may be a variety of volatile insecticides known so far, of which pyrethroid, carbamate, organophosphorus, etc. chemicals may be mentioned, of which pyrethroid chemicals may already be preferably used already. They generally have high security.

In addition, specific chemicals of this type such as metroflutrin, transflutrin, empentrine, teraletrin and proflutrin can be used which are highly active and in a small amount are effective as they can make the chemical carrier thin and small.

In addition, it is not only a 503 chemical cartridge used with a blower type chemical diffusion apparatus as described above, but it can also be attached directly to the fan in an air blower and can otherwise be integrated into the fan. In addition, it can be arranged either in an air inlet or an outlet side. Even more, it can be attached to the blow outlet opening of an air conditioner.

Referring to Figure 52, a chemical cartridge that is not part of the present invention will be described, as an example of its use, applied to a blower type chemical diffuser using a chemical cartridge to diffuse A chemical towards the atmosphere.

As shown in Figure 52, a main housing body 601 is provided with an air blower 602 and has a chemical cartridge 603 removably attached thereto in which a fan 604 of the air blower 602 is made rotate using a 605 engine to allow air to pass through the 603 chemical cartridge.

The main housing body 601 includes a base element 610 and a cover element 611, is formed with a blower mounting section 612 and a battery acceptance section 613 and has an air inlet section 614 and a section of air discharge 615.

The air blower 602 has a fan 604 and a motor 605 mounted in a housing 606 provided in the blower mounting section 612. The housing 606 has an air inlet opening 606a that communicates with the air inlet section 614 and also has an air discharge opening (not shown) that communicates with the air discharge section 615.

A battery 607 shown as comprising two dry batteries is attached in the battery acceptance section 613.

The cover element 611 is connected to the main housing body 610 so that it can be opened and closed, whereby the opening of the cover element 611 allows the chemical cartridge 603 and the battery 607 to be removed and fitted.

The chemical cartridge 603 includes a chemical retainer or body impregnated with chemical 620 and a fixation 630, although the chemical cartridge 603 is not limited to a combination of such a body impregnated with chemical 620 and fixation but can comprising a body impregnated with chemical 620 and a receptacle which will be described below or may comprise only a body impregnated with chemical 620.

The chemical-impregnated body 620 as shown in Figures 52 to 56 is made of an air-permeable or porous material that absorbs folded sheet liquid 621 that is flat and impregnated with a chemical, as shown. . Several folds of the body impregnated with chemical 620 are formed by mountain-shaped folds and alternate valley-shaped folds of the sheet material at certain widths.

The chemical-impregnated body 620 made of such a sheet material 621 that is therefore of large surface area per unit volume and which can retain liquid chemical, can retain a large amount of liquid chemical per unit of volume and in addition it can be sufficient if it is made of small size.

For example, it is possible to provide a body impregnated with thin chemical 620 containing a large amount of liquid chemical.

This sheet 621 is prevented from losing its folded shape by assembly, for example by thermally melting its peripheral edge 622, along which the folds are made to be parallel, to maintain a passage of the folds. To do this, if a folded sheet with its folds is left as they are, under an external force it tends to lose its shape and cannot maintain its original passage of the plates.

Thus treated, the sheet material 621 allows air to pass uniformly throughout its area and in turn to emit chemical from the body impregnated with chemical 620 uniformly throughout its area.

This therefore allows a volume of chemical retained in the body impregnated with chemical in a substantially uniform manner throughout its area to be consumed, thus making the use of a chemical to obtain this effective and efficient.

In the embodiment shown, the chemical-impregnated body 620 is round in its flat shape with its peripheral edge 622 in the form of a circular ring.

This does not exclude the possibility that the body impregnated with chemical 620 may be square or rectangular in its flat form; then two opposite edges of it can melt.

Fixing 630 acts to hold the peripheral edge of the body impregnated with chemical 620 to maintain its shape and prevent it from deforming. It also serves to allow the chemical cartridge 603 to be held with the fingers while preventing the chemical from contaminating the hand. Of course, air is allowed to pass through the body impregnated with chemical 620 except in its limited area where it is held by fixing 630.

Therefore, the fixing 630 has a clamping section that holds the body impregnated with chemical 620 and an air passage section through which air flows.

For example, the fastener 630 comprises a support element 631 and a fastener element 632, and the support element 631 comprises a raised adjustment ring 633 and, as a support element, a support ring 634 protruding inward from a inner face 633a of the raised adjustment ring 633 below it.

The clamping section 632 is in this case in the form of a ring that can be adjusted with a raised ring-shaped edge 633 of the support element 631.

Then, the chemical-impregnated body 620 is loaded into the support element 631 with its peripheral edge 622 adjusted with the raised adjustment ring 633 and placed on the support ring 634, and subsequently the clamping element 632 fits into the raised adjustment ring 633 with itself pressed on the peripheral edge of the chemical impregnated body 620 to hold the same between the clamping element 632 and the support ring 634 in the raised adjustment ring 633 of the support element 631.

Therefore, the ring-shaped support element 631 and the clamping element 632 together constitute the aforementioned clamping section and the space in the clamping section constitutes the aforementioned air passage section.

In this embodiment, as shown in Figure 56, when the treated sheet material 621 is held by fixing 630, it will be noted that its molten peripheral edge 622 is held in a position vertically in the intermediate part of the fixing height 630 with its upper and lower contour lines 621a and 621b protruding up and down, respectively, to an equal extent from that position vertically in the intermediate part.

Depending on the relative thicknesses of the support and clamping rings 634 and 632 that can be selected, however, it is also possible to hold the molten peripheral edge 622 of the folded sheet material 621 by means of fastening 620 and as in a first modification shown in the Figure 57 locating the sheet material 621 in the attachment 630 so that its lower contour line 621b is relatively flat and its upper contour line 621a protrudes relatively largely upwards.

In any case, it is possible to make the lower face 620a of the body impregnated with chemical 620 substantially level and preferably accurately level with the lower face 630a of the attachment 630, thereby improving the ability to place the cartridge of chemical 603 on the casing body of apparatus 601. Furthermore, since the support and clamping rings 634 and 632 can be thin, it is possible to make the fastener 630 of small thickness and size.

For example, it will be seen in the arrangement shown in Figure 52 in which the chemical cartridge 603 must be placed on an upper face with flange 606b of the housing 606, which is necessary to make the lower face 620a of the product cartridge chemical 620 is level with the bottom surface 630a of the attachment 630 to make the chemical cartridge 630 easily placed on the housing

606. Otherwise, the height H2 of the attachment 630 for the chemical cartridge 603 shown in Figure 56 tends to become greater than the height H1 of the chemical cartridge 603 shown in Figure 57 at a thickness (height) of the support ring 634.

Being not only air permeable but also absorbs liquid, the folded sheet material 621 of the body impregnated with chemical 620 after the depletion of its chemical product, specifically once the chemical cartridge is consumed by the fact that The amount of chemical it contains has diffused completely into the surrounding atmosphere, it can be supplied again and impregnated with chemical throughout its area to provide a body impregnated with chemical.

Thus, a chemical cartridge is provided, which can be used repeatedly after refilling.

Mention is made below of a preferred chemical cartridge that is suitable for refilling after exhaustion, with reference to Figures 58 and 59.

The support element 634, previously represented as the support ring, in the attachment 630 now comprises an outer and inner peripheral ring 634a and 634b and connecting bars 634c connecting them together.

Likewise, the fastener 632 of the fastener then comprises an outer and inner ring 632a and 632b and connecting rods 632c that connect them together.

With the cartridge thus constructed, the chemical-impregnated body 620 can be supplied with chemical in an area enclosed by the inner ring 632b and easily refilled.

With the fastener 630 shown in Figures 58 and 59, the chemical-impregnated body 620 having its upper and lower faces supported by and between the inner rings 632b and 634b and the connecting rods 632c and 634c, prevents it from coming down. In this case, only one of the support and clamping elements 631 and 632 can have an internal ring and connecting rods of this type.

The inner rings are of arbitrary size, shape and number and can be determined according to the size of the body impregnated with chemical 620, the material used for the folded sheet and the amount of impregnation of the chemical.

Providing an inner ring and connecting rods only for the support element 631 to form recesses on its upper face allows liquid chemical to be filled to remain in these recesses and to prevent it from escaping and collapsing.

Although not shown, an indication of filling of a chemical by a color can be provided

or a mark on a surface of the treated sheet material 621 on the chemical cartridge shown in Figure 54.

Mention is made below of additional modifications.

As shown in Figure 60, a folded sheet material 621 with its peripheral edge 622 that remains untreated (unmelted) can also be used for the chemical impregnated body 620.

Then, the fixation 630 in the fastener of the folded sheet material 621 acts to compress its unprocessed peripheral edge 622, thereby holding it firmly to prevent the folds from losing shape.

It may then be further desirable that the fastener 632 be threadedly engaged with the raised ring 633 of the support member 630 to secure the peripheral edge 622 of the folded sheet material 621.

A chemical cartridge may simply be a body impregnated with chemical 620 with its peripheral edge 622 treated as shown in Figure 53.

The incorporation of a body impregnated with chemical 620 in a receptacle 640 having an air passage zone can provide a chemical cartridge 603.

For example, in a second modification as shown in Figure 61, a ring-shaped receptacle 640 has its inner round zone that provides the air passage zone and is formed with an annular inwardly oriented recess 641 in its outer ring section. The treated peripheral edge 622 of the chemical impregnated body 620 fits into this annular recess 641 to incorporate the chemical impregnated body 620 into the receptacle 640.

In a third modification as shown in Figure 62, the unprocessed peripheral edge 622 of the chemical impregnated body 620 is fitted into this annular recess 641 to incorporate the chemical impregnated body 620 into the receptacle 640.

Thus constructed, the receptacle 640 can be held with one hand without causing the hand to be contaminated by the chemical and is easy to handle.

Although the various examples of implementation mentioned above show that the body impregnated with chemical 620 is round, with the attachment 630 and the receptacle 640 being ring-shaped, the body impregnated with chemical 620 can also be rectangular, triangular or semicircular, then fixing 630 and receptacle 640 are also rectangular, triangular or semicircular.

Therefore, the fixation 630 will be sufficient if it is configured to be able to hold and press the peripheral edge of a body impregnated with chemical 620 and present an air passage zone. Also, the receptacle 640 will be sufficient if it is configured by housing a body impregnated with chemical 620 and presenting an air passage zone.

Although the various examples of implementation mentioned above show that the chemical impregnated body 620 is flat to make the chemical cartridge thin, the chemical impregnated body 620 may be in the form of a cylinder and the receptacle 640 can be cylindrical, presenting an annular recess in which the body impregnated with chemical 620 is housed to provide a chemical cartridge.

For example, in a fourth modification as shown in Figures 63 and 64, an inner and outer cylinder 642 and 643 and a pair of end face plates 644 and 645 constitute a receptacle 640 having an annular recess 646 and an axial gap 647.

The internal and external cylinders 642 and 643 are formed with ventilation holes 642a and 643a and an end face plate 644 has an air flow opening 644a.

The chemical-impregnated body 620 in this case comprises a folded sheet material 621 that is permeable to air and absorbs liquid. This folded sheet material 621 has its peak-valley height substantially equal to a radial width of the annular recess 646 which is at a radius difference between the external and internal cylinders 643 and 642 so that it can fit into the latter. The folded sheet material 621 is adjusted so that its fold contours are adapted to opposite walls of the annular recess 646, and then impregnated with a liquid chemical.

The receptacle 640 thus loaded in its annular recess 646 with the body impregnated with chemical 620 provides a chemical cartridge 620.

The chemical cartridge 620 is removably loaded in the apparatus housing body 601.

For example, in the cartridge 603 the one end face plate 644 is formed with a cotter element protruding outward 648 in which it defines the air passage opening 644a although in the apparatus housing body 601 it is formed with an inwardly oriented key recess 649 in which it defines the air inlet opening 614 so that when the key element 649 is coupled with the key hole 649 the chemical cartridge 603 and the apparatus housing body 601 they are firmly joined while putting the air passage opening 644a and the air inlet opening 614 in communication with each other.

And, with the fan 604 of the air blower 602 driven by the engine 605, air is allowed to flow through the ventilation holes 643a of the external cylinder 643, the annular gap 646, the ventilation holes 642a of the internal cylinder 642, the axial hole 647, the air passage opening 644a, the air inlet section 614 and the air discharge section 615, thereby dragging chemical from the body impregnated with chemical 620 therein for diffusion towards the surrounding atmosphere.

Thus constructed, adapted and arranged as mentioned above, a body impregnated with chemical 620 as in the previous embodiments can retain an increased amount of chemical per unit volume and can still be made small.

According to this embodiment, with a body impregnated with chemical 620 that can retain an increased amount of chemical and its diameter can be reduced, a chemical cartridge 603 can be made of small diameter, still presenting an increased product absorption capacity chemical.

In addition, with a receptacle 640 that is made easy to handle and sealed, not only can it be easily handled, but also protects the user's hand from contamination with a chemical supported by a body impregnated with chemical 620.

In addition, although not shown, partition plates may be provided in the annular recess 646 of the receptacle 640 to prevent the folds of the folded sheet material 621 from losing shape. Furthermore, the inner cylinder 642 may have a plurality of circumferentially separated projections such that adjacent projections hold the peak of each of the folds to prevent the folded sheet material 621 from losing shape.

Although a chemical cartridge is shown mounted on the device housing body 601 of the blower type chemical diffusion apparatus so that when it is blown by an air blower 602 it can emit chemical into the surrounding atmosphere, it must it is appreciated that the chemical cartridge in this aspect of the invention is not limited to a particular use of this type thereof but can simply be used with mounting means suitable for placement in a room or the like so that it can emit spontaneously chemical into the atmosphere

In this case, the chemical cartridge can be manufactured in the form of a fan, lantern, accordion or curtain.

The sheet for use to form a folded sheet material 621 is preferably made of a woven or nonwoven textile material to meet the requirements of its air permeability and liquid absorption capacity. In addition, it is desirable that the material be resistant to chemicals depending on the particular types of chemicals used. For example, applicable raw materials include legumes, cotton, wool, linen and silk such as natural fiber, polypropylene, polyethylene, polyamide, poly (ethylene terephthalate), poly (butylene terephthalate), polysulfone, rayon, methacrylate resin and fiber of glass as synthetic fiber.

The folded sheet material 621 should have as a sheet a thickness that preferably ranges from 0.02 mm to 1.0 mm to maintain its retention and liquid absorption capacity.

In addition, to facilitate the emission of chemical products (air transmission), the sheet should preferably have a density of 0.05 to 1.0 g / cm3.

Although the folding width of the folded sheet material 621 cannot be determined flatly as it also refers to its refolding width, when the objective is to make the chemical cartridge smaller and especially thinner, it may not be it is desirable to increase the bending width since this tends to increase the thickness of the chemical; therefore, it should be desirable to determine it depending on the area of the body impregnated with chemical 620. Therefore, the bending width should normally range between 2mm and 30mm.

In the case of a cylindrical chemical cartridge as shown in Figures 63 and 64, however, the folded sheet material 621 may have a bending width greater than 30 mm.

As for the peak-to-peak distance of the folds of the folded sheet material 621, there seems to be no particular limitation imposed on it. However, the wider the distance, the smaller the amount of chemical that may be contained, and if the folds are densified, an increase in the amount of chemical absorbed also prevents air flow and the emission of chemical . Therefore, the distance should normally be no more than 10 mm and not less than 1 mm (in which the folds when visually observed are barely in contact with each other).

Not only can the folds be of uniform height (when the folding width is equal to the folding width) but they can also be irregular height (when folding width varies and the distance remains constant) or greater in its center. They can also be straight or curved centerline. If its peripheries melt thermally, a rounded periphery will result.

Materials from which 630 fixation can be manufactured include resins (poly (ethylene terephthalate), polypropylene, polyethylene, polyacetal, nylon, acrylic material, ABS and AS), synthetic paper materials and metals.

Volatile chemicals that can be used in the present invention include an insect pest control agent (insecticide, repellent, growth inhibitor, acaricide, insect control essential oil

or similar), aromatic agent, aromatic deodorant, deodorant, fungicide, disinfectant or parasite repellent, and especially such a chemical that is volatile at a common temperature or airflow conditions. A chemical of this type may preferably be at least one insect pest control agent selected from specific chemicals of this type such as metoflutrin, empentrine, teraletrin, transflutrin and proflutrin.

These chemicals are extremely active and have high mortality rates. By presenting efficacy in a small amount, they can be used desirably and may be optimal for use in a smaller chemical cartridge.

In addition to a chemical as mentioned above, a volatile regulator (petrolatum, glycol, etc.), dissolving agent (paraffin, polyalcohol, fatty ester, etc.), antioxidant, (BHT, can be added thereto) BHA, etc.), indicator (alocroic coloring agent) and ultraviolet absorber.

As mentioned earlier, the ways in which a liquid chemical is re-supplied in a chemical cartridge can visually check its supply quantity using a calibrated drip pipette, a dosing vial, a measuring vessel or a container with a measuring cup, or a mouthpiece.

In addition, since when supplying a chemical it is convenient that its time of new supply can be checked visually, it is desirable to use a body impregnated with chemical 620 that can be of known type with an indicator that displays its depletion time.

Referring to Figure 65, a blower type chemical diffusion apparatus is shown using a chemical impregnated body according to the present invention to diffuse chemical that volatilizes therefrom into the surrounding atmosphere.

In the apparatus shown, a main housing apparatus or body 701 has an air blower 702, a battery 703 and a chemical cartridge 704 that includes a body impregnated with chemical 704 housed therein, in which with a fan 702a that is rotated by a motor 702b, air is drawn through an air inlet opening 705, passes through the body impregnated with chemical 704a and is discharged through an air discharge opening 706 to emit product chemical that volatilizes from the body impregnated with chemical 704a and is transported in the air to the surrounding atmosphere.

The apparatus housing body 701 has a part 701a opposite the chemical cartridge 704 in which the latter can be disassembled and joined.

Composed of a base element 707 and a cover element 708, the apparatus housing body 701 is designed in this case, for example, to allow the cover element 708 to open and close and the user opens the housing element. 708 cover to remove the chemical cartridge 704 and battery 703 and adjust them in position.

The chemical impregnated body 704a comprises a honeycomb honeycomb body 710 and a sheet body that absorbs liquid and air permeable 720 that are impregnated with a chemical.

The honeycomb honeycomb body 710 has a large number of cores 711 that are open on its two side faces 710a and 710b in the direction of their thickness.

The sheet body 720 is disposed on one of these side faces, preferably on the side, 710b, in which the air exits, on the side face.

Preferably, the honeycomb honeycomb body 710 is of much smaller thickness than width and length, specifically a thin and "flat" body that is of large flat area, presenting a large number of open cores 711 in the direction of its thickness, and on that large area the sheet body 720 is disposed on its side where the air comes out.

The cores 711 of the honeycomb honeycomb body 710 can be of cross-section not only polygonal but can also be, for example, corrugated, circular, triangular, square or triangular.

In addition, the cores 711 can be not only laminar but also can be spirals. The cores 711 can be formed of a material that can be any of which the sheet body 729 can be formed as will be mentioned below.

These characteristics make it possible to manufacture the thin 704 chemical cartridge and therefore the device shell body 701 of small thickness.

Furthermore, reinforced by the honeycomb honeycomb body 719, the sheet body 720 can maintain its given shape.

The honeycomb honeycomb body 710 also allows air to flow through it smoothly and can effectively emit the chemical that it retains into the surrounding atmosphere without impeding the flow of air through the reinforcing sheet body 720 .

In addition, being mounted on the apparatus housing body 701 as shown in Figure 65, the honeycomb honeycomb body 710 and the sheet body 720 allow air to pass through and flow through them, allowing the chemical held in them to be transported in the air so that it emanates and diffuses into the surrounding atmosphere as fan 702a is rotated as mentioned above.

In addition, honeycomb and sheet honeycomb bodies 710 and 720 of the chemical impregnated body 704a after the depletion of the chemical being retained can be removed as the chemical impregnated body 704a of the apparatus housing body 701, placed in the state in which the sheet body 720 is located above the honeycomb honeycomb body 710 and filled with chemical. In this case, the liquid chemical body 720 is supplied with liquid chemical by adding liquid chemical dropwise in a limited area thereof, then permeating the liquid chemical product progressively throughout the entire sheet body 720 and at the same time permeating through the honeycomb honeycomb body 710 progressively throughout the honeycomb honeycomb body 710 as well. Therefore, a body impregnated with filled chemical 704a results.

More specifically, since the sheet body 720 is arranged to meet an entire area in which there is a large number of walls 712 that constitute the cores 711 of the honeycomb honeycomb body 710 and oriented in the direction of its thickness, the chemical is retained with the impregnation or bath on, along and in these walls 712.

A chemical cartridge 704 of this type that includes a body impregnated with chemical 704a with the recharge in the apparatus housing body 701 is allowed to emit chemical into the surrounding atmosphere.

The chemical filling by the dropwise addition of liquid chemical onto the sheet body 720 allows the chemical to be impregnated and retained by the honeycomb honeycomb body 710 for its entire volume as well. Since the amount of chemical to fill the sheet body 720 may be in accordance with that which is necessary to impregnate the honeycomb and sheet honeycomb bodies 710 and 720, it is possible to avoid chemical residue.

Therefore, it is possible for the user to easily regenerate a body impregnated with chemical 704a after use by filling the honeycomb and sheet honeycomb bodies 710 and 720 with chemical.

With the sheet body 720 arranged in intimate contact with one of the side faces (for example, side face 710b) of the honeycomb honeycomb body 710 in the direction of its thickness, the chemical supplied in the body is allowed of sheet 720 gently permeate in and throughout the honeycomb honeycomb body 710 (i.e., wall materials 712).

With the honeycomb foil and honeycomb bodies 720 and 710 so arranged, chemical is allowed to permeate from the foil body 720 to the honeycomb honeycomb body 710 (i.e., wall materials 712) smoothly and without failures.

In this embodiment, a retention receptacle 730 is used to bring the sheet body 720 into intimate contact with a side face (e.g., side face 710b) of the honeycomb honeycomb body 710.

The retaining receptacle 730 comprises a receptacle body element 740 and a clamping element 750 which is each in the form of a ring. The chemical-impregnated body 704a is placed in the retention receptacle 740, and the clamping element 750 engages in and engages with the receptacle body element 740 to hold the honeycomb and sheet honeycomb bodies 710 and 720 by and between them with the sheet body 720 which is in intimate contact with the one side face of the honeycomb honeycomb body 710.

This arrangement allows the sheet material 720 to come into intimate contact firmly with a side face of the honeycomb honeycomb body 710.

Mention is made below of a first modification of the chemical cartridge 704 which includes the body impregnated with chemical 704a with reference to Figures 66 to 68.

The receptacle body element 740 comprises a central support section 741, a peripheral support section 742 and a plurality of braces 743 connecting the central and peripheral support sections 741 and 742 to each other in which a space defined with the section of central support 741, the peripheral support section 742 and neighboring braces 743 connected to each other by the peripheral support section 742 is open constituting an air flow section 744 and the peripheral support section 742 has a raised support ring 745 manufactured supportive of it.

The clamping element 750 is in the form of a ring that can be adjusted with the raised ring 745.

The honeycomb honeycomb body 710 fits into the raised support ring 745 and the sheet body 720 is and is placed on and supported by the upper surfaces of the central and peripheral support sections 741 and 742 and the braces 743 in contact with them.

The clamping element 750 is adjusted with the raised support ring 745 and, in contact with a peripheral edge of the one side face 710a of the honeycomb honeycomb body 710, holds such peripheral areas of the nest honeycomb bodies of bee and sheet 710 and 720.

The central support section 741 is formed with a liquid chemical accumulation section 746 open on a support face 741, a section that opens to the outside through an inlet opening 747 formed on its side opposite the support face 741

In this arrangement, the chemical cartridge 704 (the retention receptacle 730) is removed and placed after turning it over.

And, chemical is added dropwise and is supplied through the inlet opening 747 in the liquid chemical accumulation section 746 and accumulates there.

This allows liquid chemical to permeate from the center of the sheet body 720 progressively throughout its area and at the same time permeate from the sheet body 720 through the face of the honeycomb honeycomb body 720 in intimate contact with the sheet body 720, then inside and through the sheet body 720 progressively throughout its area as well.

Mention is made below of a second modification of the chemical cartridge 704 which includes the body impregnated with chemical 704a.

As shown in Figures 69 to 70, the peripheral support section 742 of the receptacle body element 740 is formed in its support face 742a with an accumulation section of annular liquid chemical 746 that opens in its lower face through an inlet opening 747.

In this arrangement, liquid chemical is supplied in a peripheral part of the sheet body and allowed to permeate towards its central part.

Mention is made below of a third modification of the chemical cartridge 704 which includes the body impregnated with chemical 704a.

As shown in Figures 71 and 72, the receptacle body element 740 is formed in each of the central and peripheral support sections 741 and 742 with a liquid chemical accumulation section 746 and an inlet opening 747.

In this arrangement, liquid chemical is supplied both in a central part and in a peripheral of the sheet body 720 so that chemical is allowed to permeate both in its peripheral and central parts. This allows the chemical to fill the honeycomb honeycomb body 710 effectively in a short period of time.

Although it was previously shown that the sheet body 720 is located above the honeycomb honeycomb body 710 to deliver liquid chemical directly onto the sheet body 720, alternatively the sheet body 720 can be located below the honeycomb body of honeycomb 710 so that liquid chemical is supplied from above the honeycomb body of honeycomb 710 in cores 711 and then supplied to sheet body 720.

In this case, both the need to form the inlet opening 747 shown in Figures 68 and 72 and the need to make the accumulation section of liquid chemical 746 deep as shown in Figures 68 and 72 are eliminated .

For example, in a fourth modification as shown in Figures 73 and 74, a shallow liquid chemical accumulation section 746 is formed in each of the central and peripheral support sections 741 and 742.

And, liquid chemical is supplied from the cores 711 both in the central and peripheral part of the honeycomb honeycomb body 710 in the central and peripheral parts of the sheet body 720.

In addition, to identify when the chemical can be supplied, an annular collar can be applied over a clamping section opposite the liquid chemical accumulation section to indicate that the chemical must be supplied there. Alternatively, a color may be applied as an indication for the cores in which the chemical should be supplied.

Although in the previous examples of implementation the body impregnated with chemical 704a is shown mounted so that the honeycomb foil and honeycomb bodies 720 and 710 are located inside and outside, respectively, can be placed at the inverse, that is, being outside and inside, respectively.

For example, depending on the types of chemicals used, the sheet body 720 can be positioned to be oriented outwards and the honeycomb body 710 to be oriented inwards.

Furthermore, although in the previous examples of implementation the body impregnated with chemical 704a is shown presenting a sheet body 720 arranged to be in intimate contact with a side face of a honeycomb honeycomb body 710, two can be used sheet bodies 720 to be in intimate contact with the two opposite side faces of a honeycomb honeycomb body 710, respectively.

The chemical that can be impregnated in a honeycomb honeycomb body 710 of a body impregnated with chemical 704a can be an insect pest control agent (insecticide, repellent, growth inhibitor, acaricide, control essential oil insects or similar), aromatic agent, aromatic deodorant, deodorant, fungicide, disinfectant or parasite repellent, and especially such a chemical that is volatile at a common temperature or air flow conditions.

Such chemicals, if used to kill insects, may be a variety of volatile insecticides known so far, of which pyrethroid, carbamate, organophosphorus, etc. chemicals may be mentioned, of which pyrethroid chemicals may already be preferably used already. They generally have high security.

In addition, specific chemicals of this type such as metroflutrin, transflutrin, empentrine, teraletrin and proflutrin can be used which are extremely active and in a small amount are effective since they can make the body impregnated with chemical product thin and small .

Model materials from which a 720 body can be formed include natural and chemical fibers, non-woven textile material (from natural, chemical and carbon fibers), resin network (polyester, polypropylene, polyvinyl chloride), fabric (woven or knitted), paper thread (paste, linter, synthetic paper). The material can be a formed body such as in the form of a sheet, net, honeycomb honeycomb, drainage board, grid or fold, a deformable body to maintain its shape when confined, or is a flocculate or a sponge.

Of these materials, a sheet-like material of nonwoven fabric that is distinguished by its air permeability and chemical retention is preferred.

In the present invention, the ways in which a liquid chemical is supplied in a chemical impregnated body can visually check its supply quantity using a calibrated drip pipette, a dosing vial, a measuring vessel or a container with a measuring cup, or a mouthpiece.

In addition, since when supplying a chemical it is convenient that its time of new supply can be checked visually, it is desirable to use a honeycomb honeycomb body 710 in a body impregnated with chemical 704 that can be of known type with an indicator that visualizes your exhaustion time.
