Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, and in particular to a collection device and an air purifier. Background Technology

[0002] In related technologies, air purifiers draw air from the surrounding environment into the device, purify it through an internal filter module, and then return the purified air to the environment. However, in environments with a lot of pet hair, such as homes with cats and dogs, or pet shops, hair can easily clog the air purifier's filter module. Cleaning a clogged filter module requires disassembling the entire unit, which is cumbersome. Furthermore, cleaning hair from the filter module is difficult and can easily cause hair and allergens to scatter and fly around, leading to secondary pollution. Secondly, long-term clogging of the filter module also shortens its lifespan, resulting in high operating costs due to frequent filter replacements. Utility Model Content

[0063] In related technologies, air purifiers draw air from the surrounding environment into the device, purify it through an internal filter module, and then return the purified air to the environment. However, in environments with a lot of pet hair, such as homes with cats and dogs, or pet shops, hair can easily clog the air purifier's filter module. Cleaning a clogged filter module requires disassembling the entire unit, which is cumbersome. Furthermore, cleaning hair from the filter module is difficult and can easily cause hair and allergens to scatter and fly around, leading to secondary pollution. Secondly, long-term clogging of the filter module also shortens its lifespan, resulting in high operating costs due to frequent filter replacements.

[0064] In view of this, the present invention proposes a collection device that can be applied to an air purifier to improve or solve the problem of high equipment operating costs caused by the filter module being easily clogged by hair, as well as to solve problems such as troublesome cleaning and secondary pollution from hair and allergens during cleaning.

[0065] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the collection device 100 includes a breathable collection bag 110 and an installation structure (see reference). Figure 2 The elastic fastening ring 120 (120) in the bag and the breathable collection bag 110 have a collection cavity 111 and a bag opening 112 communicating with the collection cavity 111, and are used to collect hair-like materials. The mounting structure is provided at the bag opening 112. The hair-like materials include, but are not limited to, human hair, animal hair, animal fibers, fabric fibers, and fiber fluff formed by fiber shedding, or hair clumps formed by hair aggregation.

[0066] Specifically, please refer to Figures 3 to 5The air purifier comprises a housing 200, a fan 300, and a filter module 400. The housing 200 has an air duct 201, an air inlet 230 connecting to the air duct 201, and an air outlet 204. The air inlet 230 is connected to the air intake side of the fan 300, and the air outlet 204 is connected to the air outlet side of the fan 300. Under the action of the fan 300, air flows into the air duct 201 from the air inlet 230 and flows out from the air outlet 204. The air is purified by the filtration of the filter module 400 within the air duct 201, thus providing users with cleaner and more comfortable air.

[0067] The installation structure of the collection device 100 is used to detachably install the bag opening 112 of the breathable collection bag 110 at the air inlet 230, so that the collection chamber 111 of the breathable collection bag 110 is connected to the air inlet 230.

[0068] Specifically, the air to be treated flowing in from the air inlet 230 must first pass through the breathable collection bag 110 before entering the downstream fan 300 and filter module 400. Hair-like particles carried in the air to be treated are intercepted at the breathable collection bag 110 and collected in the collection chamber 111 for subsequent processing by the user. Thus, the hair-like particles are filtered out by the breathable collection bag 110, resulting in less or virtually no hair-like particles in the air flowing to the filter module 400. This avoids the problem of the filter module 400 being easily clogged by hair-like particles, which would significantly shorten its service life.

[0069] Secondly, since the opening 112 of the breathable collection bag 110 can be detachably installed with the air inlet 230 via the mounting structure, users can remove the breathable collection bag 110 from the air inlet 230 themselves to facilitate the disposal of dirt containing lint accumulated inside the breathable collection bag 110. The disposal method for this dirt is either to remove it from the breathable collection bag 110 and throw it in the trash can, then wash the breathable collection bag 110 and reuse it, or to throw the breathable collection bag 110 along with the dirt inside into the trash can, and then install a new breathable collection bag 110 into the air inlet 230.

[0070] It is understandable that in the latter treatment method, the breathable collection bag 110 is equivalent to a garbage bag, and is discarded along with the garbage inside. This not only saves users the trouble of cleaning the breathable collection bag 110 and washing it, but also prevents the lint in the dirt from accidentally escaping into the environment during the cleaning process, thus avoiding secondary pollution. In other words, it avoids secondary dust pollution. The collection device 100 in this case is equivalent to a consumable that can be manufactured and sold separately, providing consumers with a consumable that is easy to install and disassemble, and convenient for collecting and cleaning lint.

[0071] It is understandable that the filter module 400 has high filtration performance requirements (e.g., the ability to filter fine particulate matter) and a long service life, thus its manufacturing cost is usually high. However, the breathable collection bag 110 of this invention only needs to filter lint and has a short service life, therefore its manufacturing cost is lower. In other words, the cost of the breathable collection bag 110 is significantly lower than the cost of the filter module 400. Therefore, even if the old breathable collection bag 110 is discarded and replaced with a new one, compared to the frequent replacement of the filter module 400 due to lint blockage, the technical solution of this invention can still reduce the equipment operating cost of the air purifier.

[0072] This invention addresses the issue of lint buildup by installing a collection device 100 at the air inlet 230 of an air purifier and using a detachable, breathable collection bag 110 to filter out hair. This results in less or no hair in the air flowing into the filter module 400, preventing lint buildup and thus avoiding clogging. This solution addresses the problems of cumbersome operation, difficult cleaning, and secondary contamination from hair and allergens associated with cleaning the filter module 400. Furthermore, it extends the lifespan of the filter module 400, thereby reducing or eliminating the high operating costs associated with frequent replacements.

[0073] It is understood that this utility model's technical solution is particularly suitable for environments with a lot of hair, such as homes with cats and dogs, or pet stores. Of course, in environments with less hair, the rate at which the breathable collection bag 110 collects hair will be lower, and the frequency of disassembly, cleaning, or replacement of the breathable collection bag 110 will also be less.

[0074] Optionally, the breathable collection bag 110 is configured to be made of at least one of a fabric mesh, a plastic mesh, and a metal mesh. The fabric mesh can be nylon mesh, polyester mesh, or non-woven mesh; the plastic mesh can be nylon mesh or fiber mesh, etc.; and the metal mesh can be stainless steel mesh or aluminum mesh, etc. The mesh count of the breathable collection bag 110 ranges from 20 mesh to 200 mesh, for example, 50 mesh, 70 mesh, 90 mesh, or 120 mesh. It is understood that although a single hair is small, it often clumps together, especially the hair shed by cats and dogs. Therefore, the mesh count of the breathable collection bag 110 does not need to be set very high to effectively intercept hair and hair clumps, while also reducing the resistance encountered by the airflow when passing through the breathable collection bag 110.

[0075] The installation structure can take many forms; for example, please refer to [link / reference]. Figure 2 and Figure 5In the first embodiment, the installation structure includes an elastic fastening ring 120, which is disposed at the bag opening 112 and can elastically fit the bag opening 112 onto the edge of the air inlet 230. That is, by providing the elastic fastening ring 120 at the bag opening 112, the bag opening 112 becomes an elastically deformable opening. Thus, the structure is simple and easy to operate, and it reduces the risk of dirt escaping from the breathable collection bag 110 and re-polluting the environment.

[0076] Specifically, before installing the breathable collection bag 110 to the air inlet 230, an operating force is applied to enlarge the opening size of the elastic fastening ring 120 so that the opening size of the bag opening 112 is larger than the contour size of the circumferential side of the air inlet 230, so that the bag opening 112 can fit onto the circumferential side wall of the air inlet 230; then the operating force on the elastic fastening ring 120 is released, and the bag opening 112 will automatically tighten under the elastic action of the elastic fastening ring 120, thereby tightly fitting onto the circumferential side wall of the air inlet 230, thus completing the installation of the breathable collection bag 110.

[0077] When a certain amount of dirt accumulates in the breathable collection bag 110 and needs to be cleaned, since the elastic fastening ring 120 is tightly fitted around the peripheral wall of the air inlet 230, an operating force must first be applied to enlarge the opening size of the elastic fastening ring 120 so that the opening size of the bag opening 112 is larger than the outline size of the peripheral side of the air inlet 230, so that the bag opening 112 can easily detach from the peripheral wall of the air inlet 230; then the operating force on the elastic fastening ring 120 is released, and under the elastic action of the elastic fastening ring 120, the bag opening 112 will automatically shrink, or even shrink to the point of being basically closed, thereby effectively reducing the risk of dirt escaping from the breathable collection bag 110 and re-polluting the environment.

[0078] To improve the installation stability of the elastic fastener 120 on the side wall of the air inlet 230, please refer to... Figure 5 In the first embodiment, optionally, a limiting rib 234 is provided on the outer peripheral surface of the air inlet 230, and the elastic fastening ring 120 can be limited and abutted against the side of the limiting rib 234 away from the center of the collection cavity 111. Thus, when the breathable collection bag 110 is installed, after the elastic fastening ring 120 moves outward and passes the limiting rib 234, it can be tightly fitted onto the outer peripheral surface of the air inlet 230 and cannot be retracted due to the obstruction of the limiting rib 234. Of course, in other embodiments, the limiting rib 234 may not be provided; for example, a limiting annular groove may be provided on the outer peripheral surface of the air inlet 230, and the elastic fastening ring 120 can be adapted to be embedded in the limiting annular groove.

[0079] Of course, when disassembling the breathable collection bag 110, it is not necessary to apply operating force first to enlarge the opening size of the elastic fastening ring 120. Instead, the breathable collection bag 110 can be dragged directly away from the air inlet 230. This will also allow the elastic fastening ring 120 and the bag opening 112 to automatically enlarge and come out of the peripheral wall of the air inlet 230.

[0080] In the second embodiment, the mounting structure includes Velcro, with one of the hook side and the loop side of the Velcro located at the edge of the air inlet 230 and the other at the edge of the bag opening 112. That is, the breathable collection bag 110 and the air inlet 230 are detachably mounted using Velcro. This results in a simple structure that is easy to assemble and disassemble.

[0081] It is understandable that when the collection device 100 is sold as a consumable item, it may only include the hook side or the loop side of the Velcro, without needing to be sold as a whole. For example, if the hook side of the Velcro is fixedly installed on the peripheral wall of the air inlet 230 by means of adhesive or screw, then as a consumable item, the collection device 100 only needs to have the loop side of the Velcro on the breathable collection bag 110. The user can then install the breathable collection bag 110 with the loop side onto the hook side of the air inlet 230 to complete the replacement of the consumable item.

[0082] In the third embodiment, the mounting structure includes a first magnetic attractor and a second magnetic attractor that are magnetically attracted to each other. The first magnetic attractor is located at the edge of the bag opening 112, and the second magnetic attractor is located at the edge of the air inlet 230. That is, the breathable collection bag 110 and the air inlet 230 are detachably installed by magnetic attraction. When the bag opening 112 of the breathable collection bag 110 is installed in place on the air inlet 230, the first magnetic attractor and the second magnetic attractor will attract each other to constrain the breathable collection bag 110 to the air inlet 230. Thus, the structure is simple and easy to assemble and disassemble. At least one of the first magnetic attractor and the second magnetic attractor is configured as a magnet such as neodymium iron boron, and the other can be either a magnet or a magnetic metal such as steel.

[0083] In the fourth embodiment, the installation structure includes a zipper. One zipper strap is located at the edge of the bag opening 112, and the other zipper strap is located at the edge of the air inlet 230. The two straps can be joined or separated. That is, the zipper enables detachable installation between the breathable collection bag 110 and the air inlet 230. This results in a simple structure that is easy to assemble and disassemble. Specifically, one strap can be glued or sewn onto the peripheral wall of the air inlet 230, and then another strap can be glued or sewn onto the breathable collection bag 110. The two straps can be joined or separated by sliding the zipper pull.

[0084] It is understandable that when the collection device 100 is sold as a consumable item, it may consist of only one zipper strap, rather than being sold as a whole with both zipper straps. For example, if a zipper strap and a zipper pull are fixedly installed on the peripheral wall of the air inlet 230 by means of adhesive or screwing, then as a consumable item, the collection device 100 only needs to have another zipper strap on the breathable collection bag 110. The user can then install the breathable collection bag 110 with the zipper strap onto the zipper strap of the air inlet 230 to complete the replacement of the consumable item.

[0085] In the fifth embodiment, the mounting structure includes a mounting bracket, on which the edge of the bag opening 112 is mounted. The mounting bracket is connected to the edge of the air inlet 230 via a snap-fit ​​structure and / or screws. That is, a mounting bracket is provided on the breathable collection bag 110, and the bag is connected to the air inlet 230 via this bracket. Thus, the structure is simple and easy to implement.

[0086] In the fifth embodiment, optionally, the mounting bracket is a frame structure, with the bag opening 112 fitted onto the frame opening of the mounting bracket, and the collection cavity 111 communicating with the air inlet 230 through the frame opening of the mounting bracket. Thus, the mounting bracket also serves to support and constrain the outer contour of the bag opening 112, thereby ensuring complete alignment and seamless communication between the bag opening 112 and the air inlet 230. Of course, in other embodiments, the mounting bracket can also have other structural forms, such as including two mounting rods, with the two mounting rods respectively disposed on opposite sides of the bag opening 112.

[0087] In the sixth embodiment, the installation structure includes a matching card plate 130 and a card slot 252. The edge of the air inlet 230 is provided with the card slot 252. The middle part of the card plate 130 is provided with an air passage hole 131 corresponding to the air inlet 230. The edge of the bag opening 112 is connected to the periphery of the card plate 130. The card plate 130 can slide into the card slot 252 in the direction intersecting with the air inlet 230.

[0088] Specifically, in the sixth embodiment, two slots may be provided on the opposite sides of the air inlet 230, such as the left and right sides, with the slot openings facing each other. When installing the card plate, the card plate's orientation is adjusted so that its surface is perpendicular or nearly perpendicular to the axis of the air inlet. Then, the left and right sides of the card plate are aligned with the two slots respectively. The card plate is then moved from top to bottom or bottom to top so that the left side slides into the left slot and the right side slides into the right slot, until the air passage on the card plate is aligned with the air inlet 230. It can be understood that the two slots on the opposite sides of the air inlet 230 act as sliding grooves during the installation and removal of the card plate. The card plate can be made of cardboard, plastic, iron, or wood, etc., and this application does not specifically limit its form. Thus, the installation structure has low cost and facilitates the installation and removal of the breathable collection bag 110.

[0089] Alternatively, slots can be provided on all three side edges of the air inlet 230, with the three slots connected together. Two opposing slots serve as sliding grooves for the left and right side edges of the card plate to slide into. When the card plate moves to the point where the air passage is aligned with the air inlet 230, the lower side edge of the card plate inserts into the third slot. Broadly speaking, the three slots together form a U-shaped groove, with one side opening allowing the card plate to slide in or out.

[0090] The collection device 100 also includes a one-way valve that is rotatably disposed at the bag opening 112. The one-way valve is normally closed but can be opened by inward rotation under airflow. That is, in this embodiment, the collection device 100 has a built-in one-way valve. When the collection device 100 is removed, the one-way valve is in a closed state, sealing the bag opening and preventing dirt from leaking out of the breathable collection bag 110. For example, in an embodiment where the mounting structure includes a slot and a plate, the one-way valve can be rotatably mounted on the plate, and the one-way valve closes to seal the air passage of the plate. In this way, even if the bag opening cannot be tightened due to the indeformability of the plate, the one-way valve can still effectively seal the bag opening, thereby preventing dirt from leaking out of the breathable collection bag 110. Of course, in other embodiments, the one-way valve can also be disposed on the air inlet 230.

[0091] Of course, in other embodiments, the mounting structure can also be a free combination of the above-mentioned structural forms. For example, the mounting structure includes an elastic fastening ring 120, a first magnetic attractor, and a second magnetic attractor.

[0092] In the seventh embodiment, the collecting device 100 further includes a support structure (not shown in the figures) corresponding to the collecting cavity 111, the support structure being used to constrain the outer contour of the collecting cavity 111. It should be noted that the outer contour of the constrained collection cavity 111 can be either a support structure located inside the collection cavity 111 to support the breathable collection bag 110 and maintain a certain three-dimensional shape for both the breathable collection bag 110 and the collection cavity 111, such as a cuboid shape; or a support structure located outside the collection cavity 111 and connected to the periphery of the breathable collection bag 110 (e.g., by adhesive) to maintain the breathable collection bag 110 in a certain shape, such as a cuboid shape; or a support structure located outside the collection cavity 111 but not connected to the periphery of the breathable collection bag 110, only connected to the edge of the bag opening 112. Under the negative pressure generated by the fan 300, the breathable collection bag 110 will deform and bulge due to the airflow, but because it is constrained by the support structure, it cannot deform and bulge at will, and can only deform and bulge within the space defined by the support structure.

[0093] The support structure can be mounted on either the housing 200 or the collection device 100. In the embodiment where the support structure is mounted on the collection device 100, the support structure can be sold separately as a consumable along with the breathable collection bag 110, or it can be detachably mounted with the breathable collection bag 110 for continuous use. When the support structure is detachably mounted with the breathable collection bag 110 for continuous use, only the breathable collection bag 110 and its mounting structure need to be replaced. In this case, the support structure can be either fixedly connected to the housing 200 or detachably connected to the housing 200.

[0094] In the seventh embodiment, optionally, a support structure is disposed around the outer periphery of the breathable collection bag 110. In this case, the support structure can be connected to or separated from the peripheral side of the breathable collection bag 110. Thus, the breathable collection bag 110 maintains a certain shape within the space defined by the support structure, preventing it from becoming entangled or knotted due to airflow, which would reduce the amount of hair that can be collected in the collection cavity 111. This ensures that the breathable collection bag 110 can collect more hair.

[0095] Secondly, since the support structure is located outside the breathable collection bag 110, it is not easily contaminated by dirt inside the collection chamber 111, and dirt is not easily retained on the support structure during the disassembly and disposal of the breathable collection bag 110. In this way, the difficulty of cleaning the support structure can be reduced, and the risk of dirt retained on the support structure accidentally falling into the environmental space and causing the environmental space to be contaminated again can be reduced.

[0096] In the seventh embodiment, optionally, the support structure is configured as a cylindrical support frame, with multiple ventilation holes on the cylindrical wall connecting the collection chamber 111. These ventilation holes connect the collection chamber 111 and the air duct 201, allowing air inside the breathable collection bag 110 to flow to the fan 300. Thus, the cylindrical support frame has good structural strength and rigidity, providing continuous and effective support and constraint for the breathable collection bag 110.

[0097] In embodiments where the mounting structure includes a mounting bracket, the support structure and the mounting bracket may optionally be connected. Further, the support structure and the mounting bracket may be integrally formed. This simplifies the structure of the collection device 100, reduces its manufacturing costs and assembly steps, and enhances the connection strength between the support structure and the breathable collection bag 110, preventing structural failure due to detachment. Of course, in other embodiments, the support structure and the mounting bracket may be separate components, or there may be no direct connection between them.

[0098] In the eighth embodiment, the support structure is located inside the collection chamber 111. This ensures that the breathable collection bag 110 maintains its shape and effectively prevents it from tangling or knotting, eliminating the need for the user to perform any additional operations to organize the bag. Furthermore, in this embodiment, the support structure and the breathable collection bag 110 are both consumables; that is, when disassembling the breathable collection bag 110 containing waste, it can be discarded along with the mounting structure and support structure. A newly purchased collection device 100 includes a new breathable collection bag 110, mounting structure, and support structure.

[0099] Please see Figures 1 to 3 This utility model also proposes an air purifier, which includes a housing 200, a fan 300, a filter module 400, and a collection device 100. The specific structure of the collection device 100 is as described in the above embodiments. Since this air purifier adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0100] Please refer to the following: Figure 5The housing 200 includes an air duct 201, an air inlet 230 connected to the air duct 201, and an air outlet 204. A fan 300 is located in the air duct 201, with its inlet side connected to the air inlet 230 and its outlet side connected to the air outlet 204. A filter module 400 is located in the air duct 201. The opening 112 of the breathable collection bag 110 of the collection device 100 is connected to the air inlet 230. Specifically, the filter module 400 and the fan 300 are both located downstream of the breathable collection bag 110. That is, the airflow flows directly into the breathable collection bag 110 from the air inlet 230, passes through the pre-filter of the breathable collection bag 110 to remove lint, and then passes through the high-efficiency filter of the filter module 400 before being discharged into the ambient space. Optionally, the filter module 400 can be a single filter element, such as a HEPA filter, or a composite filter element; this application does not specifically limit this.

[0101] Generally speaking, although hair-like objects float in the air, in relatively calm environments, they will eventually fall to the ground due to gravity, thus accumulating in large quantities on the ground.

[0102] To improve the efficiency and effectiveness of the air purifier in collecting hair, the air inlet 230 can optionally be located at the bottom of the casing 200. This allows hair on the ground to be more easily drawn into the air inlet 230 and the breathable collection bag 110 along with the airflow, and then intercepted by the breathable collection bag 110, thus enabling the hair on the ground to be cleaned more quickly. Alternatively, in other embodiments, the air inlet 230 can be located in the middle of the side wall, top wall, or bottom wall of the casing 200. When the air inlet 230 is on the bottom wall, it faces downwards and has a certain gap with the ground to allow hair to pass through.

[0103] Please see Figure 2 and Figure 5 Optionally, the bottom wall of the air inlet 230 is provided with a guiding slope 233, which extends downwards in an outward direction. Thus, the guiding slope 233 acts as a ramp, better guiding hair-like debris on the ground into the air inlet 230 with the airflow, thereby improving the device's collection and cleaning effect on hair-like debris. Of course, in other embodiments, the guiding slope 233 may not be provided.

[0104] Please see Figure 5 Optionally, the lower edge of the air inlet 230 is flush with or lower than the bottom surface of the housing 200. This reduces the gap between the lower edge of the air inlet 230 and the ground, thereby reducing the amount of lint trapped in this gap and further improving the device's lint collection and cleaning efficiency. Of course, in other embodiments, the lower edge of the air inlet 230 may be higher than the bottom surface of the housing 200.

[0105] Please see Figure 5 Optionally, the filter module 400 is located on the air inlet side of the fan 300, with the fan 300, filter module 400, and breathable collection bag 110 arranged sequentially from top to bottom. In this arrangement, the filter module 400 is located upstream of the fan 300 and downstream of the breathable collection bag 110, resulting in less contaminant in the air flowing into the fan 300, which is more conducive to keeping the fan 300 clean and functioning properly. Furthermore, the sequential arrangement of the fan 300, filter module 400, and breathable collection bag 110 from top to bottom allows for a more compact internal structure, facilitating miniaturization and thinner design. Of course, in other embodiments, the filter module 400 can also be located on the air outlet side of the fan 300.

[0106] Please see Figure 3 Optionally, the fan 300 is configured as a centrifugal fan, with its axis extending vertically. At least one outlet 204 is located on the side wall of the casing 200, and the side wall of the casing 200 where the outlet 204 is located is on a different side from the side wall of the casing 200 where the inlet 230 is located. That is, the centrifugal fan is arranged in a horizontal position. This avoids the airflow from the outlet 204 from interfering with the airflow into the inlet 230, and reduces the risk of hair near the inlet 230 being blown up by the airflow from the outlet 204, thus ensuring that hair on the ground is orderly sucked into the breathable collection bag 110. Secondly, the horizontal position of the centrifugal fan and the location of the outlet 204 on the side wall of the casing 200 not only make the airflow within the duct 201 smoother, but also reduce the height of the equipment, which is beneficial for the thin design of the equipment.

[0107] Of course, in other embodiments, the centrifugal fan may also be in a vertical position. For example, the axis of the centrifugal fan extends in the front-back direction or the left-right direction, and at least one air outlet 204 is provided on the side wall or top wall of the casing 200. In other embodiments, the fan 300 may also be configured as a cross-flow fan 300 or an axial flow fan 300, etc.

[0108] In embodiments where the centrifugal fan's axis extends along the front-back or left-right direction, the centrifugal fan has single-sided or double-sided air intake, and a filter module 400 is provided on each air intake side of the centrifugal fan. That is, if the centrifugal fan has double-sided air intake, i.e., air intake sides are formed on both sides of the centrifugal fan's axis, then two filter modules are provided accordingly, and two air inlets are also provided accordingly, with one air inlet, one filter module, and one air intake side of the centrifugal fan arranged in a one-to-one correspondence.

[0109] Please see Figure 3In this embodiment, optionally, two centrifugal fans are provided, distributed along the length of the casing 200. The air duct 201 includes a connected filter chamber 202 and a fan chamber 203. Two fan chambers 203 and two air outlets 204 are provided and are relatively independent. One fan 300 corresponds to one fan chamber 203 and one air outlet 204. The air outlet 204 is located on the side wall of the fan chamber 203. The two air outlets 204 are located on opposite sides of the casing 200. The filter chamber 202 is connected below the two fan chambers 203. The filter module 400 and the breathable collection bag 110 are both located in the filter chamber 202, and the filter module 400 simultaneously covers the connection point of the two fan chambers 203 on the filter chamber 202. The air inlet 230 is located on the side wall of the filter chamber 202. Specifically, the airflow flowing into the filter chamber 202 through the air inlet 230 and the breathable collection bag 110 is highly filtered by the filter module 400 and then split into two streams that enter the two fan chambers 203 respectively. The air then flows out through the air outlets 204 on the side walls of the fan chambers 203, creating a dual-sided airflow effect. In this way, the equipment structure is more compact while increasing airflow and purification capacity. Of course, in other embodiments, only one fan 300 may be provided, or three or more may be provided.

[0110] Please see Figure 2 and Figure 5 Optionally, the housing 200 includes a main housing 210 and an air inlet panel 220. The main housing 210 has a loading / unloading port 211, and the air inlet panel 220 is detachably installed on the loading / unloading port 211 and has an air inlet 230. A mounting structure connects to the air inlet panel 220. Thus, by providing a detachable air inlet panel 220, the collection device 100 can be easily disassembled and replaced, thereby improving the ease of use of the hair collection function. Specifically, when it is necessary to disassemble and replace the collection device 100, the air inlet panel 220 is first removed from the main housing 210. Since the collection device 100 is installed on the air inlet panel 220, the collection device 100 will be removed along with the air inlet panel 220. After removing the air inlet panel 220, the breathable collection bag 110 containing the dirt is removed from the air inlet panel 220. A new breathable collection bag 110 is then installed on the air inlet panel 220. Finally, the air inlet panel 220 is reinstalled on the main housing 210, allowing the breathable collection bag 110 to extend into the filter chamber 202 through the loading / unloading port 211, thus completing the replacement of the breathable collection bag 110. Alternatively, in other embodiments, the air inlet panel 220 may not be required. For example, the housing 200 may consist of upper and lower housings. Removing the upper housing exposes the filter chamber 202 and the breathable collection bag 110 within it, allowing for replacement of the breathable collection bag 110.

[0111] Optionally, the air inlet panel 220 can be detachably connected to the body in various ways, such as by magnetic attraction, snap-fit ​​or screw connection. This application does not make any specific limitation on this.

[0112] To reduce the risk of waste escaping from the breathable collection bag 110, please refer to Figure 3 and Figure 5 In one embodiment, the air inlet 230 includes a first channel 231 and a second channel 232 that are connected to each other. The second channel 232 is located downstream and extends into the breathable collection bag 110. The cross-sectional area of ​​the second channel 232 gradually decreases from the outside to the inside. Thus, the funnel-shaped second channel 232 can provide a certain degree of unidirectional drainage to prevent dirt from flowing back out. Secondly, the funnel-shaped second channel 232 can also serve as a guide, facilitating the installation of the breathable collection bag 110 onto the peripheral wall of the air inlet 230. Of course, in other embodiments, the second channel 232 may not be provided.

[0113] Please see Figure 5 Optionally, the bottom wall of the first channel 231 extends upwards at an inward angle. Specifically, the central axes of the first channel 231 and the second channel 232 extend upwards at an inward angle, and the cross-sectional area of ​​the first channel 231 remains unchanged, causing the bottom wall of the first channel 231 to extend upwards at an inward angle. Thus, with both the bottom walls of the first channel 231 and the second channel 232 extending upwards at an inward angle, the height difference between the outlet of the second channel 232 and the bottom wall of the filter chamber 202 is relatively large. Since the lint accumulated in the breathable collection bag 110 will begin to accumulate from the bottom wall of the filter chamber 202 under the influence of gravity, this accumulated lint is unlikely to cross the outlet of the second channel 232 and flow back into the air inlet 230, thereby further reducing the probability of dirt flowing out backwards.

[0114] It should be noted that in the embodiment where a guide slope 233 is provided on the bottom wall of the air inlet 230, the guide slope 233 may optionally be provided on the bottom wall of the first channel 231.

[0115] Please see Figure 3 and Figure 5Optionally, the air purifier also includes a one-way valve 240 located at the air inlet 230. The one-way valve 240 is normally closed but can be opened by inverting under the action of airflow. This further reduces the probability of dirt flowing out backward. Specifically, when not under the action of the airflow, the one-way valve 240 is closed inside the air inlet 230 to isolate the breathable collection bag 110 from the outside. When the fan 300 is working and an airflow is generated at the air inlet 230, the one-way valve 240 is opened by the airflow to allow the breathable collection bag 110 to connect with the outside, thus allowing the airflow and lint to enter the breathable collection bag 110. Of course, in other embodiments, the one-way valve 240 may not be provided, or the one-way valve may be located at the opening of the breathable collection bag 110.

[0116] In one embodiment where an air inlet panel 220 is provided, a one-way valve 240 is provided on the air inlet panel 220. Further, the one-way valve 240 is located at the intersection of the first channel 231 and the second channel 232, and its rotation axis is located on the top wall of the air inlet 230.

[0117] It is worth mentioning that, in this embodiment of the present invention, the number of air inlets 230 and collecting devices 100 is not specifically limited, and can be one, two, or more. In some embodiments, the number of air inlets 230 and collecting devices 100 corresponds one-to-one. For example, in one embodiment, there are two air inlets 230 and two collecting devices 100, with the two air inlets 230 located on opposite sides of the housing 200, and a breathable collection bag 110 of one collecting device 100 correspondingly installed on one air inlet 230. In other embodiments, the number of air inlets 230 and collecting devices 100 is not in a one-to-one correspondence; for example, two or more air inlets 230 can simultaneously connect to the same collecting device 100.

[0118] Please see Figures 6 to 8 ,in, Figure 6 This is a partial structural diagram of another embodiment of the air purifier provided by this utility model. The diagram only shows the bottom structure of one air purifier, concealing other structures located above the illustrated structure, such as the fan and air outlet panel. Optionally, in another embodiment, the breathable collection bag 110 has at least two bag openings 112, and the housing 200 has at least two corresponding air inlets 230. The at least two bag openings 112 are connected to the two air inlets 230 in a one-to-one correspondence. Thus, by having multiple air inlets 230 and multiple bag openings 112 work together, the collection efficiency of lint can be improved.

[0119] Please refer to the following: Figure 9 and Figure 11Optionally, in another embodiment, both the bag opening 112 and the air inlet 230 are provided as two, with the two air inlets 230 located on opposite sides of the housing 200. This allows for the collection of hair-like debris from different locations within the device, achieving a more comprehensive and omnidirectional collection effect. For example, one air inlet 230 can be located on the front side of the housing 200, and the other air inlet 230 on the rear side. In this case, the two bag openings 112 of the breathable collection bag 110 can be distributed along the front-to-back direction, with one bag opening 112 facing the front air inlet 230 and the other bag opening 112 facing the rear air inlet 230. Of course, in other embodiments, two air inlets 230 may be located on adjacent sides of the housing 200, or air inlets 230 may be provided on each side of the housing 200. For example, in an embodiment where the housing 200 is rectangular, air inlets 230 may be provided on the front, back, left, and right sides of the housing 200.

[0120] It is understood that in embodiments where at least two bag openings 112 are provided, the number of breathable collection bags 110 and the number of bag openings 112 can be either in a one-to-one correspondence or a non-one-to-one correspondence. For example, in some embodiments, at least two breathable collection bags 110 are provided, and each breathable collection bag 110 has only one bag opening 112. In other embodiments, at least one breathable collection bag 110 has two bag openings 112, for example, the breathable collection bag 110 may have one bag opening 112 on each of its opposite sides.

[0121] Secondly, the number of collection chambers 111 and the number of bag openings 112 can be either in a one-to-one correspondence or a non-one-to-one correspondence. For example, in some embodiments, the same collection chamber 111 is connected to at least two bag openings 112. For example, please refer to... Figure 9 and Figure 11 When the breathable collection bag 110 has two opposing openings 112, its collection chamber 111 is a continuous cavity. In other embodiments, the same breathable collection bag 110 is divided into at least two collection chambers 111, and at least two openings 112 are connected to the two collection chambers 111 in a one-to-one correspondence.

[0122] For example, a breathable collection bag 110 can be divided into two collection chambers 111, and the breathable collection bag 110 has two opposing openings 112, each opening 112 connecting to a collection chamber 111. That is, by dividing the inner cavity of the same breathable collection bag 110 into sections, and using independent collection chambers 111 to handle the lint flowing in from different directions, the risk of lint escaping from other openings 112 due to negative pressure can be reduced.

[0123] Furthermore, the breathable collection bag 110 can be divided into multiple collection chambers 111 in various ways, and this application does not specifically limit this. For example, in some embodiments, the inner cavity of the breathable collection bag 110 is divided into multiple collection chambers 111 by sewing a sewing thread onto it. In other embodiments, the inner cavity of the breathable collection bag 110 is divided into multiple collection chambers 111 by hot pressing, melting, or welding.

[0124] Please see Figure 9 and Figure 10 Optionally, in another embodiment, the housing 200 includes a main housing 210 and a mounting base 250. The main housing 210 is provided with a loading / unloading port 211, and the mounting base 250 is detachably mounted to the loading / unloading port 211 and is provided with at least one air inlet 230. The breathable collection bag 110 is mounted to the mounting base 250 via a mounting structure. The installation operation of the main housing 210, the mounting base 250, and the breathable collection bag 110 can be performed by first assembling the breathable collection bag 110 with the mounting base 250 as a whole, and then inserting the entire assembly formed by these two components into the main housing 210 through the loading / unloading port 211. When it is necessary to disassemble and replace the breathable collection bag 110, the mounting base 250 is first removed from the loading / unloading port 211. At this time, the mounting base 250 is exposed outside the equipment, providing more operating space, facilitating the removal of the breathable collection bag 110 from the mounting base 250, and then installing a new breathable collection bag 110 onto the mounting base 250.

[0125] Of course, in other embodiments, the mounting base 250 can be installed into the main housing 210 first, and then the breathable collection bag 110 can be installed onto the mounting base 250.

[0126] Please see Figures 8 to 10 Optionally, in another embodiment, the loading and unloading port 211 is provided on one side of the main housing 210, and the side of the mounting base 250 is provided with one air inlet 230 corresponding to the loading and unloading port 211, and the other side of the main housing 210 is provided with another air inlet 230; the breathable collection bag 110 is pre-installed on the mounting base 250 so that one of the bag openings 112 is connected to the air inlet 230 provided corresponding to the loading and unloading port 211; after the breathable collection bag 110 is installed into the main housing 210 along with the mounting base 250, the other bag opening 112 is connected to the other air inlet 230 located on the main housing 210.

[0127] That is, in this embodiment, one of the two air inlets 230 is disposed on the main housing 210, and the other is disposed on the mounting base 250. The breathable collection bag 110 is first installed on the mounting base 250 to pre-constrain its two bag openings 112 in a predetermined direction and position, and to pre-align one of the bag openings 112 with the air inlet 230 located on the mounting base 250. Secondly, when the breathable collection bag 110 is inserted into the main housing 210 along with the mounting base 250, the other bag opening 112 automatically aligns with the air inlet 230 located on the main housing 210, thereby enabling the installation of the mounting base 250 and the breathable collection bag 110 in one step, simultaneously achieving the goal of aligning the bag opening 112 with the air inlet 230. This improves the ease of installation of the mounting base 250 and the breathable collection bag 110.

[0128] Please refer to the following: Figure 6 Optionally, in another embodiment, the air inlet 230 and the loading / unloading port 211 on the mounting base 250 are arranged opposite each other in the first direction, the two bag openings 112 of the breathable collection bag 110 are arranged opposite each other in the first direction, and the mounting base 250 is loaded into or removed from the loading / unloading port 211 in the first direction.

[0129] The first direction can be the front-to-back direction. That is, the two openings 112 of the breathable collection bag 110 are distributed in the front-to-back direction, the loading and unloading port 211 is located on the front side of the main housing 210, one air inlet 230 is located on the front side of the mounting base 250 corresponding to the loading and unloading port 211, and the other air inlet 230 is located on the rear side of the main housing 210. The mounting base 250 can be inserted into or removed from the main housing 210 through the loading and unloading port 211 in the front-to-back direction. After the mounting base 250 is inserted into the main housing 210, the rearward-facing opening 112 of the breathable collection bag 110 will automatically align and connect with the air inlet 230 located on the rear side of the main housing 210.

[0130] The mounting base 250 may have two slide rails 253 spaced apart in the left-right direction on its bottom surface, and the bottom wall of the main housing 210 may have a guide rail 212 extending in the front-back direction corresponding to the slide rails 253. The slide rails 253 and the guide rails 212 cooperate to facilitate the insertion or removal of the mounting base 250 from the main housing 210.

[0131] Please see Figure 9 , Figure 11 and Figure 12Optionally, in another embodiment, the mounting structure includes a mating plate 130 and a slot 252. The center of the plate 130 has an air passage hole 131 corresponding to the air inlet 230. The edge of the bag opening 112 is connected to the periphery of the plate 130. The mounting base 250 has a slot 252, and the plate 130 can slide into the slot 252 in a direction intersecting the axis of the air inlet 230. That is, in the mating structure of the plate 130 and slot 252 mentioned in the sixth embodiment above, the slot 252 is disposed on the main housing 210 of this embodiment. It can be understood that in embodiments where the housing 200 includes the main housing 210 and the air inlet panel 220, the slot 252 may be disposed on the air inlet panel 220.

[0132] The mounting base 250 can have various structural forms. For example, please refer to... Figure 9 In another embodiment, the mounting base 250 has a generally box-shaped structure with the opening facing upwards, and the opening connects to the air inlet side of the fan 300 located thereon. The front side wall of the mounting base 250 has an air inlet 230, and the rear side wall has an air passage 251 corresponding to the air inlet 230 located on the rear side of the main housing 210. The left and right edges of the air passage 251 are provided with slots 252, with the openings of these two slots facing each other. These slots 252 are used to install a retaining plate 130 connected to the edge of the rear bag opening 112. The air inlet 230 of the mounting base 250 also has slots 252 on its left and right edges, with the openings of these two slots facing each other. These slots 252 are used to install a retaining plate 130 connected to the edge of the front bag opening 112.

[0133] Please see Figure 8 , Figure 9 and Figure 12 Optionally, in another embodiment, the housing 200 further includes at least two air ducts 260 with openings at both ends. A retaining plate 130 is correspondingly fitted onto the outer peripheral surface of one air duct 260. The collection chamber 111 is connected to the air inlet 230 through the inner cavity of the air duct 260. The edge of the air duct 260 has a retaining ring protrusion 261, which is arranged opposite to the retaining plate 130 and is inserted into the retaining groove 252 together. In this way, on the one hand, by adding the air duct 260, hair can be better introduced into the breathable collection bag 110, and the probability of hair escaping outward can be reduced. On the other hand, the retaining ring protrusion 261 of the air duct 260 and the retaining plate 130 are inserted into the retaining groove 252 together, which is equivalent to reusing the retaining groove 252 as the installation structure of the air duct 260, which simplifies the structure of the mounting base 250 and improves the installation reliability of the retaining plate 130 and the breathable collection bag 110.

[0134] Of course, in other embodiments, the air duct 260 and the snap ring protrusion 261 may not be provided, and only the snap plate 130 is inserted into the snap slot 252.

[0135] Please see Figure 8 In the direction from the outside in, the cross-sectional area of ​​the air guide duct 260 gradually decreases, at least in its inner end region. This reduces the risk of lint escaping from the breathable collection bag 110. Of course, in other embodiments, the cross-sectional area of ​​the air guide duct 260 may remain constant in the direction from the outside in, or the cross-sectional area of ​​the air guide duct 260 may gradually increase.

[0136] It should be noted that the collection device 100, as a consumable, may only include a breathable collection bag 110 and a card plate 130 fixed to the breathable collection bag 110, while the air duct 260 can be used continuously and is not considered a consumable. In this case, the card plate 130 and the air duct 260 may have a simple abutting relationship, or the card plate 130 may have adhesive backing to be bonded and fixed to the snap ring protrusion 261 of the air duct 260. The card plate 130 may be in the form of cardboard, plastic sheet, iron plate, or wood, etc., and this application does not specifically limit it.

[0137] Specifically, please refer to Figures 9 to 12 In another embodiment, the breathable collection bag 110 is provided with a bag opening 112 and a card plate 130 on both the front and rear sides. The four corners of the mounting base 250 are provided with card slots 252 extending in the vertical direction. The two front card slots 252 are used to install one card plate 130 and one air guide duct 260, and the two rear card slots 252 are used to install another card plate 130 and another air guide duct 260. When installing the breathable collection bag 110 and the retaining plate 130, which are consumables, onto the mounting base 250, first slip the retaining plate 130 onto the air guide 260 so that the retaining plate 130 abuts against the inner end face of the retaining ring protrusion 261. Then adjust the posture of the retaining plate 130 and the air guide 260 so that the two side edges of the retaining plate 130 and the retaining ring protrusion 261 are aligned with the two left and right retaining slots 252, and slide it into the retaining slots 252 from top to bottom, until the air passage hole 131 on the retaining plate 130 is aligned with the air inlet 230. The process of disassembling the breathable collection bag 110 and the retaining plate 130 is the reverse, so it will not be described in detail.

[0138] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
