Description

Technical Field

[0001] This application relates to the field of air purification, and more particularly to an air purifier. Background Technology

[0002] In pet-owning homes, pet hair is one of the main air pollutants. This hair not only continuously sheds and remains suspended in the air, affecting indoor air quality, but also settles and adheres to various surfaces such as floors, furniture, and curtains, forming accumulations that are difficult to remove completely. This dual nature of the problem makes simple cleaning insufficient to effectively maintain a clean environment, necessitating air purification equipment to provide continuous and efficient air purification capabilities.

[0003] Current air purification devices used in such scenarios generally employ a single air channel for both intake and exhaust. This single-channel structure severely limits the total amount of gas the device can process per unit time. Insufficient air intake directly prevents the device from quickly drawing in and processing the large amount of suspended hair scattered throughout a large space, thus hindering rapid air purification.

[0051] This application provides an air purifier, which includes a filter drive assembly 100. The filter drive assembly 100 includes a gas drive assembly 110 and a filter assembly 120. The gas drive assembly 110 has an air inlet and at least one air outlet channel 101. Each air outlet channel 101 has at least two air outlets. The filter assembly 120 is provided at both the top and bottom of the gas drive assembly 110. The gas drive assembly 110 is used to drive the gas filtered by the filter assembly 120 to be delivered to the air outlet.

[0052] Please see Figure 3 and Figure 4As shown, the gas-driven assembly 110 of this application has two air outlet channels 101, and each air outlet channel 101 has two air outlets, that is, the gas-driven assembly 110 has four air outlets. Since the gas-driven assembly 110 has filter components 120 at both the top and bottom, and the gas-driven assembly 110 has corresponding air inlets connected to the filter components 120 at both the top and bottom, that is, the gas-driven assembly 110 has two air inlets. With the cooperation of the two air inlets, the two air outlet channels 101 and the four air outlets, it can quickly drive external air to pass through the filter components 120 for filtration, and discharge it to the outside through the four air outlets. Compared with the existing single-duct method, it increases the air intake and exhaust volume, thereby improving the efficiency of air purification. It can quickly purify air containing suspended hair and dust, ensuring the cleanliness of the air.

[0053] The air purifier also includes a base 200 and a top seat 300. Specifically, the base 200 is located at the bottom of the filter drive assembly 100 and has a first air intake channel 201 that is connected to the air inlet. A barrier mesh is provided at the location of the first air intake channel 201. The top seat 300 is located at the top of the filter drive assembly 100 and has a second air intake channel 301 that is connected to the air inlet.

[0054] The air purifier disclosed in this embodiment has a first direction X, a second direction Y, and a third direction Z. It can be understood that the first direction X is the left-right horizontal direction, the second direction Y is the front-back vertical direction, and the third direction Z is the vertical direction.

[0055] Please see Figure 1 and Figure 2 As shown, this application mainly sets the air intake channels at the top and bottom of the entire air purifier, and sets the air outlet channel 101 in the middle of the two air intake channels in the vertical direction. That is, the air outlet channel 101 is set in the middle of the air purifier, and the corresponding air outlet is also located in the middle of the height direction of the air purifier. The purpose of this design is that when a pet (in this embodiment, a cat is used as an example) sheds hair, the hair will sink to the ground under the action of gravity. At this time, the hair on the ground will be sucked into the first air intake channel 201 by the gas suction force. Since there is a barrier net at the position of the first air intake channel 201, the hair can be blocked to the outside of the purifier through the barrier net, preventing the hair from entering the purifier and causing blockage of the gas channel, thus preventing it from playing a role in air purification.

[0056] The second air intake channel 301 at the top of the air purifier can suck up hair suspended in the air and bring the hair into the second air intake channel 301. Since there is a barrier net at the location of the second air intake channel 301, the hair will be blocked by the barrier net and will not be able to enter the purifier.

[0057] In one embodiment, the first air intake channel 201 and the second air intake channel 301 are respectively located at the bottom and top of the purifier. This not only allows for the suction of pet hair on the ground but also for the suction of hair suspended in the air, thereby blocking the hair at the barrier net. The pet hair will stick tightly to the barrier net, achieving the function of removing hair from the ground and the air while purifying the air, thus keeping the ground and the air clean.

[0058] By placing the air outlet 101 in the middle of the purifier, it is possible to prevent the blown airflow from disturbing the ground and lifting hair from the ground into the air, thus aggravating airborne pollution.

[0059] Understandably, when pet hair needs to be cleaned, simply removing the hair from the barrier screen is sufficient.

[0060] In some embodiments, the filter drive assembly 100 includes a gas drive assembly 110 and a filter assembly 120. The gas drive assembly 110 has two air outlet channels 101. The top and bottom of the gas drive assembly 110 are provided with filter assemblies 120. The two filter assemblies 120 are respectively connected to the first air inlet channel 201 and the second air inlet channel 301.

[0061] Please see Figure 2 As shown, the gas drive assembly 110 has two air outlet channels 101. It can be understood that in order to improve the suction efficiency, the gas drive assembly 110 has two power components for suction. The power component is the gas drive device 114 mentioned below. The air inlet end of each power component is connected to the first air inlet channel 201 and the second air inlet channel 301 respectively, thereby forming two gas channels, so that the two gas channels do not affect each other and are independent of each other.

[0062] In some embodiments, the gas-driven assembly 110 includes a mounting plate 111, which has a first side and a second side. Side plates 112 integrally formed with the mounting plate 111 are provided at both edges of the first side and both edges of the second side. Air inlet covers 113 are provided on both side plates 112 on the same side of the mounting plate 111. The mounting plate 111, side plates 112 and air inlet covers 113 surround to form an air outlet channel 101. Gas driving devices 114 are provided on both the first side and the second side. The gas driving devices 114 are located in the air outlet channel 101, and the air inlet end of the gas driving devices 114 faces the air inlet cover 113.

[0063] Please see Figure 3 and Figure 4 As shown, the first and second surfaces of the mounting plate 111 are the upper and lower surfaces in the height direction, respectively. Side plates 112 are provided at both sides of the upper surface of the mounting plate 111, and correspondingly, side plates 112 are also provided at both sides of the lower surface of the mounting plate 111. In this embodiment, the mounting plate 111 and all the side plates 112 are integrally formed. For example, injection molding can be used to integrally form the mounting plate 111 and all the side plates 112. The purpose of this is to prevent gaps from forming at the connection between the mounting plate 111 and the side plates 112, so that the filtered gas can overflow from the gaps and cannot be discharged to the outside according to the preset trajectory. Integral molding can create a seamless connection between the two, so that the filtered gas can be discharged to the outside according to the trajectory of the exhaust channel 101.

[0064] Please continue reading. Figure 3 and Figure 4 As shown, the side plates 112 on the upper and lower sides of the mounting plate 111 are also connected to the air inlet cover 113. An air outlet channel 101 is formed on each side of the mounting plate 111 under the enclosure of the mounting plate 111, the two side plates 112 and the air inlet cover 113. In this embodiment, the air outlet channel 101 on each side is open from front to back, that is, the air outlet channel 101 on each side has two air outlets. It can be further understood that the purifier disclosed in this embodiment has two air outlet channels 101 and four air outlets.

[0065] Correspondingly, a gas drive device 114 is installed in each air outlet channel 101, and the gas filtered and purified from the filter assembly 120 is discharged to the outside from the air outlet of the air outlet channel 101 through the gas drive device 114.

[0066] In some embodiments, the air inlet cover 113 includes a cover body 1131 detachably connected to the side plate 112. The side of the cover body 1131 opposite to the side plate 112 is recessed to form a guide surface 1132, and a first grille 1133 is provided on the guide surface 1132.

[0067] Please see Figure 5 As shown, the side of the cover 1131 facing away from the side plate 112, i.e. the side of the cover 1131 in the air intake direction, is concave to form a guide surface 1132. Specifically, the guide surface 1132 forms a groove, which can obtain a larger air intake area. Its concave arc shape has a guiding function. In order to allow the gas to enter the gas driving device 114 located in the air outlet channel 101, a first convex grille 1133 is provided at the middle position of the guide surface 1132. This allows the gas filtered and purified by the filter assembly 120 to enter the gas driving device 114 through the first grille 1133. The gas driving device 114 then discharges the filtered and purified gas to the outside through the air outlet of the air outlet channel 101.

[0068] In some embodiments, the gas drive device 114 includes a rotary drive member 1141, which is provided with a plurality of connecting arms 1142 connected to the mounting plate 111. Each connecting arm 1142 is provided with a shock-absorbing pad 1143 at the connection between it and the mounting plate 111. The rotating end of the rotary drive member 1141 is connected to a fan wheel 1144, which has an air inlet end and an air outlet end. The air inlet end faces the air inlet cover 113, and the air outlet end faces the air outlet channel 101.

[0069] Please see Figure 3 , Figure 4 , Figure 5 as well as Figure 6 In this embodiment, the gas drive device 114 is fixedly installed on the mounting plate 111. Specifically, at least two connecting arms 1142 are provided on the periphery of the rotary drive component 1141, and each connecting arm 1142 is provided with a shock-absorbing pad 1143 at the connection with the mounting plate 111. The shock-absorbing pad 1143 buffers the vibration force generated by the rotary drive component 1141 during operation, thereby reducing the noise generated. The impeller 1144 is installed on the rotating end of the rotary drive component 1141. The rotary drive component 1141 drives the impeller 1144 to rotate. The air inlet end of the impeller 1144 faces the first grille 1133 of the air inlet cover 113. That is, the gas filtered by the filter assembly 120 enters the air inlet end of the impeller 1144 through the first grille 1133. The rotation of the impeller 1144 draws the filtered gas from the first grille 1133 and discharges it to the outside.

[0070] In this embodiment, the cover 1131 has an annular groove on the side facing the mounting plate 111, and the surface of the impeller 1144 facing the air inlet cover 113 is an arc-shaped surface. The arc-shaped part of the impeller 1144 extends into the annular groove, so that the air inlet end of the impeller 1144 can fit more closely with the position of the first grille 1133, allowing the gas to fully enter the impeller 1144. Furthermore, the surface of the impeller 1144 facing the rotary drive member 1141 is recessed, so that the rotary drive member 1141 can fully enter the recessed position. Through the annular groove and the recessed setting of the impeller 1144, the space occupied by the entire gas drive device 114 in the height direction can be greatly reduced, thereby meeting the design requirements of the purifier height.

[0071] In some embodiments, the filter assembly 120 includes a housing 121 forming a receiving chamber. The receiving chamber is provided with at least one fixing frame 122, which divides the receiving chamber into a plurality of receiving cavities. Each receiving cavity is provided with filter media. The receiving chamber has a first opening and a second opening. Each receiving cavity is interconnected and communicates with both the first opening and the second opening. A support frame 123 is provided at the first opening, and a limit ring 124 is provided at the second opening.

[0072] See Figure 7 , Figure 8 as well as Figure 9 As shown, each air inlet cover 113 is equipped with a filter assembly 120. The gas filtered by the filter assembly 120 will enter the gas drive device 114 through the air inlet cover 113, and then the gas drive device 114 will discharge the filtered gas to the outside.

[0073] Specifically, in general, multiple filter media are needed to filter the gas to the required cleanliness level. In this embodiment, a combination of multiple filter media is used to purify the air. Specifically, the fixing frame 122 divides the accommodating chamber into multiple accommodating cavities, and each accommodating cavity is equipped with a corresponding filter media. By filtering with multiple filter media, the gas can be filtered and purified to the required level.

[0074] To prevent the filter media from detaching from the containment chamber due to gravity or vibration during handling, a support frame 123 is installed at the first opening of the containment chamber, and a limiting ring 124 is installed at the second opening. Under the limiting of the support frame 123 and the limiting ring 124, the filter media located in each containment chamber is confined inside, so that the filter media cannot detach from the containment chamber and can play a role in filtration and purification.

[0075] In this embodiment, the support frame 123 is integrally molded and connected to the shell 121, and the limiting ring 124 is detachably connected to the shell 121. Specifically, the limiting ring 124 is connected to the shell 121 by snap-fit.

[0076] It should be noted that, in order to ensure that the gas enters the gas drive device 114 after being filtered by each filter material, both the support frame 123 and the fixing frame 122 have hollow areas. The hollow areas ensure that the gas can pass through smoothly without obstructing its passage.

[0077] In some embodiments, the number of fixing frames 122 is N, satisfying: N≥1. When N=1, the fixing frames 122 divide the accommodating chamber into a first accommodating cavity 1211 and a second accommodating cavity 1212. A first filter material 1251 is disposed in the first accommodating cavity 1211. The support frame 123 and the fixing frame 122 restrict the first filter material 1251 within the first accommodating cavity 1211. A second filter material 1252 is disposed in the second accommodating cavity 1212. The fixing frame 122 and the limiting ring 124 restrict the second filter material 1252 within the second accommodating cavity 1212.

[0078] Please continue reading. Figure 8 and Figure 9 As shown, taking one fixing frame 122 as an example, a fixing frame 122 is set in the receiving chamber. The fixing frame 122 divides the receiving chamber into a first receiving cavity 1211 and a second receiving cavity 1212. A first filter material 1251 and a second filter material 1252 are respectively set in the first receiving cavity 1211 and the second receiving cavity 1212. Under the blocking action of the support frame 123 and the limiting ring 124, the positions of the first filter material 1251 and the second filter material 1252 are limited to prevent them from leaving the receiving chamber.

[0079] For example, the first filter material 1251 is a carbon brick and the second filter material 1252 is a HEPA filter paper. In order to adapt to the shape of the carbon brick, multiple evenly distributed hollow areas are provided on the support frame 123 and the fixing frame 122. Specifically, the hollow areas are distributed in a nine-square grid. The limiting ring 124 abuts against the upper surface of the second filter material 1252 to limit it and prevent it from shaking.

[0080] The purpose of placing the first filter material 1251 and the second filter material 1252 in the housing is that when they need to be replaced, only the entire housing 121 needs to be removed from the purifier, and then the first filter material 1251 and the second filter material 1252 can be replaced separately. It is not necessary to remove the first filter material 1251 and the second filter material 1252 from the purifier separately, which greatly reduces the cumbersomeness of replacing the filter material and improves the replacement efficiency.

[0081] In some embodiments, the limiting ring 124 includes a first rib 1241 detachably connected to the shell 121, a second rib 1242 is provided inside the first rib 1241, a rib 1243 is provided at the connection between the first rib 1241 and the second rib 1242, and the rib 1243 and the first rib 1241 form a limiting groove 1244, and the end of the side wall of the shell 121 is located in the limiting groove 1244.

[0082] See Figure 10 As shown, multiple locking blocks are arranged along the circumference of the inner sidewall of the first stiffening plate 1241. Correspondingly, multiple locking grooves adapted to the locking blocks are arranged on the top outer wall of the shell 121. The first stiffening plate 1241 and the shell 121 are detachably connected by locking the locking blocks and locking grooves. In order to limit the contact of the second filter material 1252, a second stiffening plate 1242 is integrally provided on the top of the inner sidewall of the first stiffening plate 1241. The second stiffening plate 1242 abuts against the top of the second filter material 1252 to limit its position and prevent the second filter material 1252 from falling out of the second receiving cavity 1212.

[0083] For example, the first stiffener 1241 and the second stiffener 1242 can be integrally molded by injection molding.

[0084] Furthermore, in order to improve the connection strength between the entire limiting ring 124 and the shell 121, multiple ribs 1243 are provided at intervals at the connection between the first rib 1241 and the second rib 1242, and the ribs 1243 are arranged parallel to the first rib 1241. A limiting groove 1244 is formed between the ribs 1243 and the first rib 1241. The top area of ​​the shell 121 is located in the limiting groove 1244, thereby limiting the shell 121. Under the limitation of the limiting groove 1244, the shell 121's ability to resist deformation under force can be improved to a certain extent.

[0085] In some embodiments, the base 200 includes a base plate 210, and a first limiting plate 220 and a second limiting plate 230 are respectively provided on the two edges of the base plate 210 facing the side of the filter drive assembly 100.

A hair collection assembly 400 is provided in the first air intake channel 201. The hair collection assembly 400 includes a collection shell 410, and a second grille 420 is provided on the collection shell 410. The collection shell 410 and the second grille 420 define an air intake channel 430 communicating with the outside.

[0086] See Figure 2 and Figure 11As shown, a first limiting plate 220 and a second limiting plate 230 are respectively provided on both sides of the upper surface of the base plate 210. A first air intake channel 201 is formed under the enclosure of the base plate 210, the first limiting plate 220 and the second limiting plate 230. The first air intake channel 201 is designed to be transparent in the front and back directions, that is, the first air intake channel 201 has two air intake channels in the front and back, which improves the air intake efficiency. The upper opening of the first air intake channel 201 is connected to the filter assembly 120 at the bottom, so that the air from the air intake channel enters the filter assembly 120 for filtration.

[0087] To prevent hair on the ground from entering the filter assembly 120 through the first air intake channel 201 and clogging the filter material, a collection shell 410 is installed in the first air intake channel 201. The upper opening of the collection shell 410 faces the filter assembly 120. A second grille 420 is detachably installed at the upper opening of the collection shell 410. Specifically, the second grille 420 is detachably connected to the collection shell 410 by a snap-fit ​​method. The collection shell 410 and the second grille 420 define an air intake channel 430, which is open at both ends, i.e., it has two air inlets. To further prevent hair from entering the filter assembly 120, a barrier mesh is installed inside the second grille 420 to block hair and prevent it from entering the filter assembly 120 and clogging the filter material.

[0088] When it is necessary to clean the hair located on the barrier mesh, simply slide the hair collection component 400 out of the first air intake channel 201, remove the second grille 420 from the collection shell 410, clean the hair on the barrier mesh of the second grille 420, and then reattach the second grille 420 with the barrier mesh to the collection shell 410. Finally, slide the collection shell 410 into the first air intake channel 201 to complete the installation of the hair collection component 400.

[0089] In some embodiments, the top seat 300 includes a grille 310 and a cover plate 320, the grille 310 and the cover plate 320 defining a second air intake channel 301, a third grille 500 is provided in the second air intake channel 301, and a barrier mesh is provided on the third grille 500; the cover plate 320 includes a first plate 321 and a second plate 322, the first plate 321 and the second plate 322 cooperate to form a mounting cavity, at least one easy-to-remove component 330 is provided in the mounting cavity, the easy-to-remove component 330 is used for detachable connection of the grille 310 and the cover plate 320.

[0090] Please see Figure 2 and Figure 12As shown, the third grille 500 is installed into the second air intake channel 301 formed by the grille plate 310 and the cover plate 320 by sliding. The barrier mesh on the third grille 500 blocks suspended particles in the air, preventing them from entering the filter assembly 120 and clogging the filter media. When it is necessary to clean the suspended particles or hair on the barrier mesh, simply slide the third grille 500 out of the second air intake channel 301 to clean the suspended particles or hair on the barrier mesh. Finally, slide the cleaned third grille 500 back into the second air intake channel 301 to complete the installation. It can be understood that in order to facilitate the sliding of the third grille 500, the grille plate 310 has a corresponding slide rail, so as to facilitate the sliding of the third grille 500 into the second air intake channel 301.

[0091] To facilitate the disassembly and installation of the cover plate 320 and the grid plate 310, a disassembly assembly 330 is provided on the first plate 321 for quick disassembly and installation of the grid plate 310 and the cover plate 320, thereby improving the production efficiency of the purifier and facilitating the disassembly and maintenance of the purifier.

[0092] For example, the barrier net is a mesh yarn.

A heating element can be selectively installed inside the climbing mat, and a power supply circuit is installed in the mounting cavity. Electrode elements are installed on the second plate 322 and electrically connected to the power supply circuit. After the connection end of the heating element is connected to the electrode element, the climbing mat is heated by the heating element to meet the pet cat's temperature requirements. For example, to precisely control the temperature of the climbing mat, a corresponding temperature sensor can be installed on the second plate 322 for real-time monitoring. Furthermore, a weighing sensor can be installed at the connection between the cover plate 320 and the grid plate 310 to weigh the pet cat sitting on it. Correspondingly, to control the temperature and view the weight, a corresponding controller can also be installed. The controller has a wireless receiving and transmitting module, through which the temperature can be remotely adjusted and the weight can be viewed.

[0095] In some embodiments, the first plate 321 has a first side and a second side, and the easy-to-disassemble component 330 is disposed at the first side position.

The plurality of elongated holes 3311 are fitted with guide posts on the corresponding first plate 321. A baffle 3321 is disposed on the first plate 321. The sliding shell 331 has an inner cavity. An elastic element 332 is disposed in the inner cavity. One end of the elastic element 332 abuts against the baffle 3321, and the other end of the elastic element 332 away from the baffle 3321 abuts against the inner wall of the inner cavity. An inclined guide groove 3312 is disposed on one side of the sliding shell 331. An unlocking component 333 is slidably disposed on the side wall, and the unlocking component 333 abuts against the inclined guide groove 3312. A locking part 3313 is disposed at the end of the sliding shell 331. A plurality of first locking blocks 334 are fixedly disposed on the grid plate 310. The first locking blocks 334 are distributed on the first side and the second side of the first plate 321. The first plate 321 is provided with a relief groove 3341 corresponding to the first locking block 334. The first locking block 334 at the first side position passes through the relief groove 3341 and locks with the sliding shell 331. At least one second locking block 3342 is also disposed on the first plate 321 at the second side position. The first locking block 334 at the second side position passes through the relief groove 3341 and locks with the second locking block 3342.

[0096] Please see Figure 2 , Figure 12 , Figure 13 as well as Figure 14 As shown, two sliding shells 331 are provided on the right side of the first plate 321. Specifically, two guide posts are provided at the position of each sliding shell 331. The elongated hole 3311 of the sliding shell 331 is sleeved on the guide post, and a baffle 3321 is fixedly provided on one side of one of the guide posts. One end of the elastic member 332 located in the inner cavity of the sliding shell 331 abuts against the baffle 3321, and the other end abuts against the inner wall of the inner cavity. In addition, an unlocking member 333 is slidably provided on the first plate 321. The unlocking member 333 has an inclined guide surface. In the initial state, under the elastic force of the elastic member 332, the inclined guide surface of the unlocking member 333 abuts against the inner side wall of the inclined guide groove 3312, and the locking part 3313 is locked and fixed to the first locking block 334 on the right side of the grid plate 310, while the first locking block 334 on the left side is locked to the second locking block 3342, thereby realizing the locking of the entire second plate 322 and the grid plate 310.

[0097] For example, the first plate 321 has two snap-fit ​​parts 3313 on the right side and two second snap-fit ​​blocks 3342 on the left side. During snap-fit ​​installation, the clearance groove 3341 is first set at the position of the first snap-fit ​​block 334, and then the first snap-fit ​​block 334 passes through the clearance groove 3341. Next, the first plate 321 is moved in the lateral direction so that the first snap-fit ​​block 334 on the left side snaps into the second snap-fit ​​block 3342, and the first snap-fit ​​block 334 on the right side snaps into the snap-fit ​​part 3313, thereby completing the snap-fit ​​of the entire cover plate 320.

[0098] When unlocking is required, simply press the unlocking component 333 and move it towards the inclined guide groove 3312. Under the contact between the inclined guide surface of the unlocking component 333 and the inner side wall of the inclined guide groove 3312, the elastic force of the elastic component 332 is overcome, causing the sliding shell 331 to move away from the first locking block 334, thereby disengaging the locking part 3313 from the first locking block 334. Next, simply move the cover plate 320 laterally to disengage the first locking block 334 on the left from the second locking block 3342, thus completing the disassembly of the cover plate 320 and the grid plate 310.
