Description
Technical field
The present invention at first relates to a kind of method with the hand held cleaner dust suction, wherein, the dust dust collecting container of at first packing into, for example in the bag dust filter, then with its removing, also by a kind of absorbent, for example active carbon absorbs stink.
Background technology
This method is known, wherein adopts the absorption filter in order to absorb stink, and their chief component is the loading material that is used for the absorbent of bonding stink generation material and is applicable to fixed adsorbent.Adopt porous material as absorbent, in many cases applied activated carbon for example.But also can adopt other materials, for example the organic polymer of zeolite or porous.Absorbent is made up of particle mostly, and particle can exist with different shapes and particle diameter.They are by different bearing structures, and as foam, fabric, nonwoven, honeycomb etc., mode in accordance with regulations is distributed in the filter.A kind of like this stink filter is contained in the instrument in such a way, and promptly the air that is transferred simultaneously at tool work flows through it.Common this filter is contained on the preceding suction side of fan, so that because of the temperature that raises behind motor/fan unit the adsorption equilibrium in filtering is not brought adverse influence.Known in addition to cover undesirable stink adopts the impregnated with fragrances of porous in indoor air-purifier and dust catcher medium.More known in this respect monolithics and coccoid, they are placed in the filter bag or are contained in the air flow path.The deposition of stink generation material in dust catcher proposed special requirement.With for example different in indoor air-purifier, the dust that receives in dust catcher is detained and is collected in bag dust filter or other the special-purpose dust collecting containers.The dust of collecting rests in the regular hour in filter bag or the container.The microbial degradation of various dust constituents has produced a large amount of undesirable stink generation materials during this period.Under the situation of dust catcher, the known arrangement significant disadvantage is, as with because to flow transmission and flow air flows into the result of the stink generation electrodeposition substance of stink filter, the deposition of stink generation material is carried out simultaneously in dust catcher work basically.On the one hand, the through-flow that interrelates with it causes the undesirable high pressure loss of filter.In addition, high odor unit in the suction air that produces suddenly after connecting dust catcher requires filter that extraordinary absorption power is arranged.
Summary of the invention
In view of above-mentioned prior art, technical purpose of the present invention at first is, develops the method with the hand held cleaner dust suction in an advantageous manner, that is especially is suppressed at the stink wave that takes place suddenly behind the connection dust catcher when taking low pressure loss into account.
This purpose at first and mainly realizes based on the described method of claim 1, wherein, supposes in direct input of absorbent or the adding dust-collecting cavity.Provide a kind of method according to this design, wherein with foul smell generation material at the place of its generation bonding.Be to realize this point, absorbent just be placed in the dust that is sucked near.The amount of absorbent can be smaller, for example, each traditional dust-collecting cavity substantially 3 and 30g between, preferably 5 and 50g between.Absorbent especially is in the absorbent particulate state that loosely adds or inserts.Air-flow when stink generation material is not only worked by dust catcher transmits to absorbent.Exactly, this transmission especially also during this instrument quits work the diffusion of the generation material by stink carry out.Adopt the invention of being advised to eliminate the pressure loss that is caused by filter in an advantageous manner, filter is flow through by air when tool work.In addition, prevented a large amount of stink generation material aggregations in bag dust filter or dust collecting container, this is because formed stink generation material constantly spreads also bonding there to absorbent.This means, different with the filter of known stink, a large amount of stink generation material of absorptance at short notice.By diffusion type stink of the present invention filter thereby can be with medium absorption dynamically working, the stink wave of emerging strong in the time of can not up tool taking place.The stink molecule of discharging has immediately been eliminated in employing when the dust suction behind up tool by method of the present invention.Absorbent can directly be imported or add in the dust-collecting cavity in diverse ways.For example it is contemplated that, the first time aspiration procedure begin preceding or when each aspiration procedure begins, absorbent added in the dust-collecting cavity, add in the bag dust filter in case of necessity.In this regard, might provide a kind of absorbent, for example with fragment/spherical or the active carbon that exists as fiber, a being present in the bag, this bag can be packed into wherein before using bag dust filter or dust-collecting cavity for the first time by the user with packing into.This absorbent bag for example is made of the thin supatex fabric that paper or meltblown constitute the ventilative especially material in a place.In order to accomplish absorbent spatial distribution fully in dust-collecting cavity or in bag dust filter in the method, a plurality of less bags that contain absorbent are inserted in suggestion, and 5 two bags that restrain active carbons are for example respectively arranged.Propose in the replaceable structure of this method, absorbent is present in dust-collecting cavity or the bag dust filter by the form of disperseing.Do like this and confirmed following advantage already, promptly the dust of absorbent and suction is in close state of contact, so stink generation material can especially easily spread to absorbent.The user can for example insert the absorbent of ormal weight or insert in the dust-collecting cavity by the filling mouth of bag dust filter by means of a measuring container.Alternatively, the absorbent of active carbon form also can be placed in the paper bag aly.Therefore the user can be before the aspiration procedure first time begins, that is after putting into a new bag dust filter or after emptying dust-collecting cavity, the absorbent of the predetermined umber of filling.Another substitute mode regulation is placed on absorbent on the floor that will clean, and in the dust that is sucked enters dust-collecting cavity or bag dust filter.Therefore, absorbent sucks in empty the ripple dirt bag or dust-collecting cavity as loose unpacked material with the form of particle.Here also can imagine, absorbent can diffuse on the floor that will aspirate by measuring container.Propose in another kind of alternative plan with the absorbent that scatters ormal weight, absorbent is placed in the reservoir vessel that is in dust-collecting cavity or the bag dust filter, and in the process of dust suction by from the reservoir vessel sucking-off.For example can enter the bag of adorning an edge opening in the opening or the container of a cup-shaped at bag dust filter or dust-collecting cavity suction air, after changing bag dust filter or the dust catcher behind the emptying dust-collecting cavity when putting into operation for the first time, or at dust-collecting cavity or hold in the process of the filter chamber of bag dust filter closing, therefrom absorbent is inserted in bag dust filter or the dust-collecting cavity.Also can imagine in this case,, absorbent be discharged automatically so that be distributed in this chamber by local failure reservoir bag or container at least.It is contemplated that some schemes in addition, in these schemes, container is provided with one can or move to the lid of the open position that discharges absorbent by suction airstream by the negative pressure that exists in dust-collecting cavity or bag dust filter.
The invention still further relates in addition and be used for dust catcher, especially be applied to according to the bag dust filter in or the multinomial described method in the right 1 to 5, wherein, in this case, initial stink blast when connecting dust catcher in order to reduce, there is a kind of absorbent in suggestion by the form of disperseing in bag dust filter.According to this design, the dust of absorbent and suction is in close state of contact, so stink generation material can especially easily spread to absorbent.Based on this, stink produce material in the place of its generation bonding on the spot.Confirmed already in this respect that particularly advantageous was that this diffusion type stink filter in bag dust filter inside can not occur in the stink blast of emerging strong when connecting dust catcher with medium absorption dynamically working.In this case, can for example adopt the polymer of active carbon, zeolite or porous as absorber material, they exist with fragment/spherical or as fiber.The Size Distribution of absorbent, chemical species (bactericide and fungicide material) and quantity with the volume and the use field of bag dust filter, that is estimate that the material that will aspirate is suitable.Important here point at first is to adsorb as far as possible effectively undesirable stink and produces material, and to this, the ratio of the macropore in absorbent, mesopore and micropore is relevant.In addition, the operation technique standard also is very important.For example, the absorbent of bag dust filter has a characteristic that is evenly distributed in the bag according to the present invention, and can be deposited on the characteristic on the inboard of bag wall as far as possible enduringly.At this on the one hand, might stipulate that also these require to be satisfied by the broken charcoal of fine granular.But also can consider to adopt other material, for example pulverous molecular sieve.Advantageously can also add the medium (for example silica gel) of bonding moisture, so that the life condition of microorganism in bag dust filter degenerated and meanwhile improve the adsorption capacity of active carbon.It is contemplated that under the simplest situation graininess, that is after changing new bag dust filter, is dispersed on the floor that will aspirate and sucks in the empty bag dust filter as the absorbent of bulk cargo before the first time, aspiration procedure began.Then, this absorbent contacts closely with the dust of suction, thereby stink generation material can be spread to absorbent especially easily.Alternative is absorbent might be placed in the reservoir vessel that is fixed on the bag dust filter outside, is used for entering in the bag dust filter by hand.By this way, when a new bag dust filter is inserted dust catcher, for example bag of having filled a part of sorbing material and for example removably being fixed on the bag dust filter fixed head is taken off and tears, so that the sorbing material that will be contained in the bag scatters in the bag dust filter by suction inlet.The bag of this pattern also can be attached troops to a unit in bag dust filter by form in bulk, has such possibility thus for the user, that is, can directly be sprinkled in the bag dust filter or be distributed on the floor that will aspirate being contained in sorbing material in the bag.As another kind of alternative, the present invention proposes in the ventilative overcoat that absorbent is included in a special use that is in bag dust filter inside., apply mechanically a kind of ventilative material manufacturing in addition here, for example thin supatex fabric that is made of paper or meltblown is made.This absorbent bag can just be inserted in the bag dust filter in factory.But such possibility is also arranged, and it is in bulk or removably be provided on the fixed head of bag dust filter to be about to this absorbent bag.The user inserts this absorbent bag in the bag dust filter by import before bag dust filter comes into operation for the first time, and the size of absorbent overcoat should be suitable with the cross section of bag dust filter import in this case.In this case, preferably, the surface extension degree of overcoat is the part of bag dust filter inlet diameter size.For guarantee that further absorbent distributes on the space fully in bag dust filter, advise in bag dust filter, can containing or in bag dust filter, can inserting a plurality of absorbent bags.Advise in addition in an overcoat, always containing a plurality of adsorbent particles.For example advise in a bag dust filter, putting two bags that 5 gram active carbons are respectively arranged.In another alternative structure of the present invention, propose, one can be contained on the bag dust filter inwall by the absorbent reservoir vessel that air-flow or negative pressure are opened.For example, a reservoir vessel that extends in the bag dust filter import at first can be set, when it connects dust catcher for the first time after changing bag dust filter,, move into bag dust filter inside from import by air-flow or the negative pressure that in bag dust filter, exists.At this container for example can be a bag that is filled with absorbent, and this bag initial fixation is near the import inward flange.It is removed from entrance region under air-flow or suction function, and its content can escape into the inner chamber of bag by the opening of establishing in the container afterwards.Form as an alternative, this container also can be punch format, in this case when connecting dust catcher container along perforated tear and discharge the absorbent that comprises.Replace form as another kind, this container also can calyculus, so that initially seal the import cross section of bag dust filter.Can imagine in addition, container is equipped with near the edge of fixed head downside, filling access.For example can establish a toroidal container around filling access at the fixed head downside, it is peeled off from fixed head with the release absorbent by air-flow or this container of existing negative pressure when connecting dust catcher for the first time, or the effect by air-flow or negative pressure moves on to a position that discharges absorbent with a lid or an analog that absorbent is retained in the container in container.Possibility in addition, making absorbent be arranged on one can be by tearing in the reservoir vessel of opening, for example at a bag, the suction joint register of this container and bag dust filter.Before bag dust filter came into operation for the first time, the user can tear this container according to the present invention, so that the absorbent that includes is distributed in the bag dust filter.This structure optimization ground uses when passing the suction joint opening that aspirates the bag dust filter fixed head when the suction joint cuts out in the filter chamber of fixing filter bag, and wherein, the suction joint links to each other with suction tube aspect gas flow.Therefore, close in the filter chamber that the absorbent reservoir vessel that is provided with aliging of suction joint opening in the closed procedure is sucked that joint is torn and thereby open so that absorbent discharged and be distributed in the bag dust filter.Proved already particularly advantageous be select particle diameter 0.15 and 0.25mm between active carbon powder and screenings be less than 2% low-level on as absorbent.Particularly advantageous is that also can to adopt diameter 0.01 to 0.1mm and fibre length be 10 to 100mm NACF.The CTC value of being made by coconut husk also is especially efficiently greater than 60% active carbon powder.
The invention still further relates in addition and be used for dust catcher, especially be applied to by the dust-collecting cavity in or the multinomial described method in the claim 1 to 5, wherein, in order to reduce initial stink blast when connecting dust catcher, there is the absorbent of discrete form in suggestion in dust-collecting cavity.This dust catcher is known, and here the dust of Xi Ruing is deposited in the dust-collecting cavity in the system of no filter.The dust-collecting cavity of filling can take out from tool outer casing for emptying.According to this design of the present invention, the dust of absorbent and suction is in close state of contact, so stink generation material can especially easily spread to absorbent.Therefore stink generation material in its spot bonding on the spot.Proved already in this respect that particularly advantageous was just can work the stink blast of emerging strong in the time of can not occurring in the connection dust catcher with medium absorption power in inner this diffusion type stink filter of dust-collecting cavity.As an example, the polymer of active carbon, zeolite or porous can be used as absorber material in this case, and they exist with fragment/spherical or as fiber.The Size Distribution of absorbent, chemical species (bactericide and fungicide material) and quantity, with the volume and the use field of bag dust filter, that is the predetermined material that will aspirate is suitable.Important here point at first is to adsorb as far as possible effectively undesirable stink generation material, and to this, the ratio of the macropore in absorbent, mesopore and micropore is conclusive.In addition, the operation technique standard also is very important.For example, the absorbent of dust-collecting cavity has the characteristic that is evenly distributed in the dust-collecting cavity according to the present invention, and can be deposited on the characteristic on the inboard of chamber wall as far as possible enduringly.At this on the one hand, also might satisfy these requirements by the broken charcoal of particulate very.But also can consider to adopt other material, for example pulverous molecular sieve.Advantageously can also add the medium (for example silica gel) of bonding moisture, so that the life condition of microorganism in bag dust filter degenerated and meanwhile improve the adsorption capacity of active carbon.It is contemplated that under the simplest situation the absorbent of graininess bulk cargo that is behind the emptying dust-collecting cavity, is dispersed on the floor that will aspirate and sucks in the empty dust-collecting cavity before the first time, aspiration procedure began.Therefore this absorbent contacts closely with the dust of suction, thereby stink generation material can be spread to absorbent especially easily.The scheme of replacing is absorbent might be placed in the reservoir vessel, so that manual entering in the dust-collecting cavity.By this way, after the dust-collecting cavity emptying, for example bag of having adorned a part of sorbing material is torn and the sorbing material that is contained in the bag is sprinkled in the dust-collecting cavity.
By means of such distribution pouch, also the sorbing material that wherein contains can be distributed on the floor that to aspirate.As a kind of alternative, propose absorbent and be included in the ventilative overcoat of a special use that is in dust-collecting cavity inside., apply mechanically a kind of ventilative material manufacturing in addition here, for example a kind of thin supatex fabric that constitutes by paper or meltblown.The user inserts this bag in the dust-collecting cavity when dust-collecting cavity comes into operation for the first time, and the overcoat size of absorbent should be suitable with the cross section of dust-collecting cavity import in this case.Here preferably the surface extension degree of overcoat is the part of dust-collecting cavity inlet diameter size.For guaranteeing that further absorbent has sufficient spatial distribution in dust-collecting cavity, advise in dust-collecting cavity, can containing or in dust-collecting cavity, can inserting a plurality of adsorbent bags.Be defined in addition in the overcoat and always contain a plurality of adsorption particles.For example, two bags that 5 gram active carbons are respectively arranged are put in suggestion in a dust-collecting cavity.In by another alternative design of the present invention, stipulate, one can be contained on the dust-collecting cavity inwall by the absorbent reservoir vessel that air-flow or negative pressure are opened.This container for example can be a bag that is filled with absorbent, and this bag for example is fixed on the inboard of dust-collecting cavity inwall at first.Because air-flow or suction function, it is stripped from or tears, and its content can be escaped in the dust-collecting cavity by set opening by pocket afterwards.Form as an alternative, this container also can be designed as punch format, in this case when connecting dust catcher container along perforated tear and discharge the absorbent that comprises.What replace is that this container also can form cup-shaped.In addition, also can imagine absorbent is contained in one can be by tearing in the reservoir vessel of opening, for example in a bag.According to the present invention, the user can tear this reservoir vessel before dust-collecting cavity comes into operation for the first time, so that the absorbent that includes is distributed in the dust-collecting cavity.This tearing also can be finished in the process of dust-collecting cavity shutoff operation automatically, for example by the apparatus part in instrument one side is inserted dust-collecting cavity.Proved already particularly advantageous be select particle diameter 0.15 and 0.25mm between and the screenings ratio be less than 2% low-level active carbon powder as absorbent.Particularly advantageous is that also can to adopt diameter 0.01 to 0.1mm and fibre length be 10 to 100mm NACF.The CTC value of being made by coconut husk also is especially efficiently greater than 60% active carbon powder.
At last, the invention still further relates to a kind of ventilative overcoat that is included in, the absorber material in the non-woven material for example, wherein, the size of overcoat and dust-collecting cavity or bag dust filter import cross section are suitable.Based on this design, can be inserted in the dust-collecting cavity or in the bag dust filter by import by the absorber material of the overcoat encirclement of breathe freely.Obtaining an important advantage thus is, absorbent be positioned at the dust that is inhaled into just nearby, thereby prevented a large amount of stink generation material aggregations in dust-collecting cavity or bag dust filter, this be because stink generation material continuously to absorbent diffusion and bonding there.Also suggestion in this respect, the surface size of overcoat is equivalent to the part of dust-collecting cavity or bag dust filter inlet diameter size.For example the surface size of overcoat can be approximately 1/5th to 1/10th of inlet diameter size.Here for example each absorbent bag can be equipped with preferably 5 gram sorbing material, for example active carbons of 3 to 10 grams.
Be used to filter stink or be used to constitute diffusion or design that stink filters has outstanding advantage by top illustrated the present invention.For example different with known standard absorption filter, stink filter (absorbent no matter be contained in the bag also the form to disperse) directly is not in the flow path.In addition, when adopting the absorbent of discrete form, bearing structure can be saved, different geometric layouts can be imagined in this case.Also have, compare and to ignore with the pressure loss that causes by standard filter by the pressure loss that diffusion type stink filter according to the present invention causes.In addition, even also can bring into play its effect at the instrument state that quits work, thereby prevent from bag dust filter or in dust-collecting cavity, form a large amount of stinks to produce material by diffusion type stink filter of the present invention.The remarkable technology of simplifying interrelates when cancelling bearing structure and saving material and manufacturing.In addition, adsorption capacity can be by absorbed dose of radiation and its need adapt (for example the dust that strong odor arranged that by pet feeding caused) of user by adding independent selection.Also proof advantageously because structure diffusion type stink of the present invention filter can be disposed during when changing bag dust filter or at each emptying dust-collecting cavity each.Therefore the stink filter is in the state with optimal adsorption characteristic after replacing/emptying.In addition, diameter has been realized high efficient less than the activated carbon of 0.5mm.

The specific embodiment
At first illustrate that with reference to Fig. 1 has a dust catcher 1 that is fixed on the bag dust filter 3 in the filter chamber 2.When dust catcher 1 work, suction nozzle 5 districts of motor/fan unit 4 one side on the floor that schematically shows produce negative pressure, remove dust and dirt particle by means of this negative pressure from the floor 6 that will purify, and be transported in the bag dust filter 3 via the suction channel (not shown) by suction airstream.Motor/fan unit 4 is connected bag dust filter 3 downstreams along airflow direction.
The bag dust filter 3 interior dusts of packing into stop the regular hour there.Microbial degradation owing to contained material in the various dusts produces stink generation material during this period, and these stink generation materials are absorbed as the back describes in detail.
For this reason, in bag dust filter 3, import or add the absorbent 7 of active carbon, zeolite or porous polymer form.
According to exemplary embodiment shown in Figure 1, for this purpose, absorbent 7 is dispersed in by means of measuring container 8 on the floor 6 that will aspirate, afterwards when dust catcher 1 is started working in the dust that is sucked enters bag dust filter 3.Measuring container 8 has the function of the sugar bowl of spreading, and discharges the absorbent 7 of predetermined fraction whereby after toppling over measuring container.But adsorption capacity can be adapted with special requirement by the absorbent 7 (by scattering out the absorbent of more shares) that adds the amount of selecting separately by the user.For example, if dust because pet feeding and stink is strong can be put the absorbent of two shares on the floor 6 that will aspirate.
Preferably, scattering absorbent or will absorbent 7 suck and import in the bag dust filter 3 changing finishes when bag dust filter rear dust collector 1 starts for the first time once.
Fig. 2 schematically illustrates dust catcher 1, and it has a separator and a dust-collecting cavity 9 that is connected thereafter for the dirt/dust granule that holds suction.The removable when needed bag dust filter that this dust catcher 1 does not have according to first embodiment.The dust-collecting cavity of exactly here filling 9 is emptying in addition when needed.
In its this form of this dust catcher, same owing to the dust that receives will be detained the regular hour, thus cause the microbial degradation of contained material in the different dusts, consequently produce undesirable stink generation material.Especially when connecting dust catcher 1, cause undesirable initial stink blast thus, resisted by in dust-collecting cavity 9, putting into absorbent 7 according to the present invention.
As among first embodiment of reference Fig. 1, in this second embodiment, absorbent 7 also is dispersed on the floor 6 that will purify by means of measuring container 8, and after this in the dust that will aspirate enters dust-collecting cavity 9.
By absorbent 7 is added in bag dust filter 3 or the dust-collecting cavity 9, absorbent is in close state of contact with the suction dust, so stink generation material can especially easily spread to absorbent.
Fig. 3 has represented a bag dust filter 3, it can be before using for the first time filling absorbent 7.In this case, the embodiment that has illustrated above this filling is similar to carries out by means of measuring container 8, and measuring container is used to discharge the absorbent of a predetermined fraction.Absorbent 7 is sprinkled into by bag dust filter 3 imports 10 and directly adds in the bag dust filter 3.In this case, the absorbent 7 of the amount that the user equally might be by adding independent selection need adapt characterization of adsorption and its.
In addition, a absorbent is scattered from measuring container 8, can in the dust-collecting cavity of dust catcher shown in Figure 21, carry out equally.
As another kind of alternative, absorbent 7 also can use for the user by the form of dividing composition in advance, and for example with the form of the bag 11 that contains a absorbent, and its loosely and bag dust filter 3 are packaging together.Shown in Figure 4 and 5, a kind of like this distribution pouch 11 that constitutes reservoir vessel 13 also can be attached troops to a unit in bag dust filter 3, for example by can dividually bag 11 being placed on the upside of bag dust filter fixed head 12.Bag 11 can be placed on the fixed head 12 by the user with ignoring, and here the basic configuration of bag 11 can be designed to similar in appearance to an arrow by illustrated embodiment.Take off bag 11 from fixed head 12 after, the absorbent that is included in the bag 11 can be sprinkled in the bag dust filter 3 by import 10.For this reason, bag 11 can be torn along a preferred perforation line.
Replace form as another kind, absorbent 7 can be contained in the reservoir vessel 13 for using.
In this regard, represented a kind of embodiment among Fig. 6 and 7, wherein 13 bags of shape ground of reservoir vessel are shaped, and have around edge 14.Contain the absorbent 7 of scheduled volume at the bag that so is shaped.
The reservoir vessel 13 of bag shape is positioned and bag dust filter fixed head 12 imports 10 corresponding positions, and around the zone at edge 14 in, it is can be between the fixed head 12 of multilayer two-layer loosely equipped and fix.In addition fixed head 12 by each layer outside the traditional approach layer adhered to one another, does not connect mutually in that part of zone at fixing bag edge 14.Also can imagine in this respect, the two-layer annulus around bag rim 14 of fixing bag shape reservoir vessel 13 by clamping is provided with groove, for example embossing.
After bag dust filter 3 had inserted dust catcher 1 and after this started apparatus, the reservoir vessel 13 of bag shape sucked in the bag dust filters 3 from import 10 under the suction function of air-flow or foundation in bag dust filter 3.Afterwards, absorbent 7 can be distributed in the bag dust filter 3, for this reason, the reservoir vessel of this bag shape 13 along around the part periphery at edge 14 do not seal.
Based on this design, the absorbent of bag dust filter 3 automatic filling predetermined fraction, after this it be present in the bag dust filter 3 with the state that disperses at this.
Fig. 8 and 9 has represented to be fixed on the reservoir vessel 13 another kind of designs of fixed head 12 downsides.Represented a reservoir vessel 13 of seeing to be essentially rectangle in plane here, it covers import 10 at the downside of fixed head 12.Reservoir vessel 13 is being bonded on the fixed head downside on the whole surface in the zone between the import 10 of fixed head 12 and narrow side.Reservoir vessel 13 has an opening 16 away from the free end of this bonded areas 15, and it is sealed by a plug 17 that is connected material one on the reservoir vessel 13 when bag dust filter shown in Figure 93 unused states.
The reservoir vessel 13 that includes predetermined fraction absorbent 7 is essentially from supporting type, and with in not use location shown in Figure 9, reservoir vessel 13 almost is parallel to the mode that fixed head 12 extends.
Air-flow that produces when dust catcher 1 starting or the negative pressure of setting up bag dust filter 2 in cause reservoir vessel 13 towards the deflecting down of bag dust filter inside, and meanwhile siphon away plug 17 so that with opening 16 releases.Afterwards, the absorbent 7 of storage can be discharged from and be distributed in the bag dust filter 3.
Also can imagine in this respect, reservoir vessel 13 is designed to form paper or tubular film of opening, and it is (for example as the result who free end is inserted in the import 10) below the end folds and be fixed on fixed head 12 imports 10.
The another kind of embodiment different with the embodiment that has just illustrated is illustrated among Figure 10.The figure shows the reservoir vessel 13 of paper or tubular film form, its folding free end is fixed on fixed head 12 downsides.In illustrated embodiment, this realizes by a kind of wax binding agent that can throw off easily.The beginning of suction airstream makes free end peel off from wax glue 18, so that discharge absorbent 7.
According to Figure 11, as the scheme that another kind can Gong be selected for use, reservoir vessel 13 can be provided with perforation 19.Reservoir vessel is the form of bag or bag, and it for example is bonded to the following example of fixed head 12 in the edge of fixed head, superimposedly around import 10.Perforation line preferably with the justified margin of import.
When dust catcher 1 starting, this reservoir vessel 13 by air-flow or the negative pressure that bag dust filter 3 in, forms along perforation 19 whole or just the part tear, after this, the opening by formation in perforation 19 districts can freely enter the absorbent 7 of storage in the bag dust filter 3.
Usually, at reservoir vessel 13 is among the embodiment of bag or flexible pipe form, the fact is, the absorbents 7 that are stored in peelable or the reservoir vessel 13 opened are all discharged from reservoir vessel 13, and this discharge is by sucking bag dust filter 3 supported from container absorbent.
For between suction channel and the bag dust filter 3 by a suction joint 20 that passes import 10 guidings at the dust catcher that flows and is communicated with, the release that is stored in the absorbent 7 in the reservoir vessel 13 also can be by realizing by suction joint 20 destruction reservoir vessels 13.
This scheme is illustrated in Figure 12 and 13 with exemplary forms, wherein, is fixed on the downside of fixed head 12 to cover import 10 according to reservoir vessel embodiment illustrated in fig. 11 13 in Figure 12.When the filter chamber 2 that holds bag dust filter 3 closes, pass the suction joint 20 of the import 10 of fixed head 12 and tear reservoir vessel 13 along perforation 19, container is fallen in the bag dust filter 3 afterwards.Stored absorbent 7 can drop out from disrupted reservoir vessel 13.Any residue in reservoir vessel 13 can be when dust catcher 1 starting in the bag dust filter 3 of container suction from then on.
Figure 13 has represented the reservoir vessel 13 of a cup-shaped, and it is provided with one around edge 21.The latter is fixed between multilayer fixed head 12 two-layer.For this reason, one deck has an annular groove around import 10 at least, to hold limit 21.
The cup-shaped reservoir vessel 13 that the position is gone in the import 10 includes an absorbent backup (a store ofabsorbent).
This reservoir vessel 13 its profiles are consistent with the cross section of import 10 basically also for example to be made with paper material.
When changing bag dust filter and closing filter chamber 2 after this, suction joint 20 pass that import 10 is inserted and in this process by tearing the reservoir vessel 13 that this container destroys cup-shaped simultaneously in the zone of container cover 22 with in container bottom 23 zones, stored in this case absorbent 7 also can freely enter in the bag dust filter 3.
In addition, Figure 14 has represented a kind of design of replacement, wherein, cup-shaped reservoir vessel 13 is fixed near the edge of fixed head 12 downsides, import 10, this reservoir vessel 13 has bottom 23, for example split along boring a hole by the negative pressure of air-flow or foundation when dust catcher 1 starting or tear in this bottom 23, so that discharge absorbent 7.
The variety of way of illustrated filling bag dust filter 3 also can be used in dust-collecting cavity shown in Figure 29 basically.Absorbent 7 as bulk cargo has outstanding advantage, and especially, it can contact closely with the dust that sucks, so stink generation material can be especially easily to absorbent 7 diffusions.
As shown in figure 15, another kind of possibility is that absorbent 7 is contained in the ventilative overcoat 24 of a special use.For example, can adopt the coccoid bag of a plurality of adsorbent particles in this case.
The bag 25 of this filling part absorbent can factory loosely be contained in the bag dust filter 3.But also can imagine, these bags 25 are thrown away before bag dust filter 3 or dust-collecting cavity 9 put into operation into wherein by the user.For this reason, it is corresponding with the part of the diameter dimension b of bag dust filter 3 interior imports 10 or suction joint opening that degree a is extended on the surface of regulation overcoat 24, or corresponding with dust-collecting cavity 9 under the situation of dust catcher shown in Figure 2.For example the surface of overcoat 24 extension degree a can equal 1/5th to 1/10th of import 10 diameter dimensions substantially.
For the absorbent 7 that guarantees to be contained in the overcoat 24 has sufficient spatial distribution in bag dust filter 3 or dust-collecting cavity 9, adopt a plurality of little bags 25 that absorbent 7 is housed.
As the result of above-mentioned embodiment according to the inventive subject matter, absorbent 7 be in suction dust near.Not only eliminated the stink generation material of when dust catcher is worked, being carried to absorbent thus, and this conveying during quitting work, this apparatus is undertaken by the diffusion of stink generation material also by air-flow.Prevented from bag dust filter 3 to assemble a large amount of foul smell generation materials, this is because institute forms continuously the foul smell generation material that spreads to absorbent 7 bonding there.The diffusion type stink filter that so constitutes can realize with medium absorption power, need not to worry the stink blast that can emerge strong when up tool.
The absorbents of introducing in the bag dust filter 3 by the form of disperseing 7 (referring to Fig. 1 to 14) have the characteristic that is evenly distributed in the bag dust filter 3, can be deposited on the characteristic on the inwall of bag dust filter 3 or dust-collecting cavity 9 as far as possible enduringly.Advantageously also can add the medium of bonding moisture, silica gel for example so that make microorganism in bag dust filter 3 or the life condition in dust-collecting cavity 9 degenerate, and meanwhile improve the adsorption capacity of absorbent.
