Technical Field

[0001] This application relates to the field of air treatment technology, and in particular to an air treatment device. Background Technology

[0002] Air purifiers use multiple layers of filters to filter pollutants in the air. After prolonged use, dust, hair, and other pollutants tend to accumulate on the filter surface, requiring timely cleaning to maintain filtration efficiency. However, most air purifiers currently only offer one cleaning method for their filters, which fails to meet the diverse filter cleaning needs of users and has limited cleaning effectiveness.

This achieves modularity of the roller brush assembly and the vacuuming assembly in the air handling device, allowing users to choose to install either the roller brush assembly or the vacuuming assembly on the housing as needed to form a roller brush cleaning mode or a vacuuming cleaning mode for the filter assembly, improving user autonomy. Moreover, after one of the roller brush assembly and the vacuuming assembly has finished cleaning, it can be replaced with the other, forming a sequential operation of two cleaning methods for the filter assembly, improving the cleaning effect of the filter assembly.

[0021] The pressure plate in the roller brush assembly can concentrate the contaminants carried away from the surface of the filter assembly by the roller brush to at least one end of the roller brush along the first direction, thereby improving the space utilization of the dust collection chamber 320 of the dust collection box. The pressure plate can also clean the contaminants attached to the surface of the roller brush away from the filter assembly in a timely manner, ensuring the continuous cleaning effect of the roller brush on the filter assembly.

[0022] The vacuum cleaner assembly features an inlet on the connecting wall of the housing, which connects to the mounting port on the casing. The cross-sectional area of ​​the inlet increases from the end closer to the filter assembly to the end farther away, creating an amplification effect on the airflow entering the vacuum cleaner assembly through the inlet. This allows contaminants carried in the airflow to be quickly discharged through the dust outlet of the vacuum cleaner assembly, improving cleaning efficiency. Furthermore, the "narrow slit" design of the inlet enhances the suction power of the filter assembly, ensuring thorough cleaning of the deeper layers of the filter, rather than just the surface.

[0023] The cross-sectional area of ​​the suction component decreases from the end closer to the filter assembly to the end farther away from the filter assembly. This forms a funnel-shaped structure, which increases the suction area of ​​the suction component acting on the surface of the filter assembly, thereby improving suction efficiency.

[0062] The air handling device provided in this application is illustrated using an air purifier as an example, but it is not limited to air purifiers.

[0063] This application provides an air handling device 100, with reference to... Figure 1 and Figure 15 The air handling unit 100 includes: a main body 10, a filter assembly 20, a roller brush assembly 30, and a dust collection assembly 40.

[0064] Reference Figure 1 and Figure 15 The main body 10 includes a housing 11 and an air inlet 101 and an air outlet 102 that are connected to each other. (See reference...) Figure 5 The filter assembly 20 is disposed inside the housing 10. The filter assembly 20 can be used to filter the air entering from the air inlet 101 so that the filtered air is output from the air outlet 102, thereby achieving air filtration and purification.

[0065] The roller brush assembly 30 and the dust collection assembly 40 are configured to be installed on the housing 11 interchangeably. The roller brush assembly 30 and the dust collection assembly 40 can act on the surface of the filter assembly 20 to remove contaminants from the surface of the filter assembly 20.

[0066] Air purifiers use multiple layers of filters to filter pollutants in the air. However, after prolonged use, dust, hair, and other pollutants tend to accumulate on the filter surface, requiring timely cleaning to maintain filtration efficiency. Currently, most air purifiers only offer one cleaning method for their filters, which fails to meet diverse user needs and provides limited cleaning effectiveness.

[0067] The air handling device 100 provided in this application embodiment configures the roller brush assembly 30 and the dust collection assembly 40 to be interchangeably mounted on the housing 11, so that the roller brush assembly 30 and the dust collection assembly 40 can respectively act on the surface of the filter assembly 20 to remove contaminants from the surface of the filter assembly 20. This achieves modular arrangement of the roller brush assembly 30 and the dust collection assembly 40 in the air handling device 100, allowing the user to choose to install the roller brush assembly 30 or the dust collection assembly 40 on the housing 11 as needed to form a roller brush cleaning mode or a dust collection mode for the filter assembly 20, improving the user's autonomy and choice. Moreover, in the process of cleaning the filter assembly... During the cleaning process of filter assembly 20, one of the roller brush assembly 30 and the vacuuming assembly 40 can be replaced with the other after cleaning is completed. That is, after the roller brush assembly 30 completes the roller brush cleaning, the roller brush assembly 30 can be removed from the housing 11 and the vacuuming assembly 40 can be installed on the housing 11 to form a vacuuming cleaning of filter assembly 20. Alternatively, after the vacuuming assembly 40 completes the vacuuming cleaning, the vacuuming assembly 40 can be removed from the housing 11 and the roller brush assembly 30 can be installed on the housing 11 to form a roller brush cleaning of filter assembly 20. This allows for the sequential execution of two cleaning methods for filter assembly 20, improving the cleaning effect of filter assembly 20.

[0068] Among them, reference Figure 1 and Figure 15 The main body 10 also includes an airflow generating component 12. The specific structure of the airflow generating component 12 is not specifically limited in this embodiment, as long as it can output airflow. For example, the airflow generating component 12 includes a fan and an exhaust hood. The exhaust hood is connected to the top of the housing 11, and the air outlet 102 is disposed on the exhaust hood. The fan includes fan blades and a fan motor. The fan blades are connected to the fan motor, and the fan blades rotate under the action of the fan motor, forming an airflow channel within the housing. This allows airflow to enter the housing 11 through the air inlet 101, flow through the filter assembly 20, and then be discharged from the air outlet 102 on the exhaust hood, thereby filtering pollutants in the air and improving air quality.

[0069] Reference Figure 1 and Figure 15 The air handling unit 100 has a first direction X, and the air inlet 101 and the air outlet 102 are arranged opposite to each other along the first direction X. In some other embodiments, the air inlet 101 can be opened on the side wall of the housing 11, which can be selected according to the actual use requirements.

[0070] Wherein, the first direction X is parallel to the height direction of the air handling device 100 and perpendicular to the bearing surface of the air handling device 100. For example, the air handling device 100 is placed on the ground and the first direction X is perpendicular to the ground, or the air handling device 100 is placed on a table and the first direction X is perpendicular to the table.

[0071] In some embodiments, the filter assembly 20 is rotatably disposed inside the housing 11. This rotatable design allows the roller brush assembly 30, when installed in the housing 11, to work in conjunction with the rotating filter assembly 20 to perform roller brush cleaning on the entire surface of the filter assembly 20, thus improving the cleaning effect and efficiency of the roller brush cleaning. Similarly, when the vacuum assembly 40 replaces the roller brush assembly 30 and is installed in the housing 11, the vacuum assembly 40, in conjunction with the rotating filter assembly 20, can perform vacuum cleaning on the entire surface of the filter assembly 20, thus improving the cleaning effect and efficiency of the vacuum cleaning.

[0072] In addition, the rotation of the filter assembly 20 can reduce the concentration of pollutants. This can be understood as the pollutants always entering from a certain position of the housing. For example, a pet always likes to rub against a certain position of the housing 11. The hair generated during the rubbing process always concentrates at a certain position of the filter assembly 20, putting great pressure on the filter assembly 20. The rotation of the filter assembly 20 can disperse the pollutants that concentrate from a certain position, thereby improving the purification effect.

[0073] The main body 10 also includes a first rotating assembly (not shown in the figure), to which the filter assembly 20 is connected, and the filter assembly 20 rotates around a first direction X under the action of the first rotating assembly. The first rotating assembly includes a rotating drive and a first rotating disk, which is connected to the rotating drive and drives the filter assembly 20 to rotate under the driving action of the rotating drive. The rotating drive can be a rotary motor, but is not limited to this. The output shaft of the rotary motor drives the gear to rotate, and the first rotating disk has circular teeth that mesh with the gear. Under the driving action of the rotary motor, the gear drives the circular teeth to rotate together with it. The number of rotating drive components can be set according to requirements, and can be one, two, or three.

[0074] In some embodiments, refer to Figures 2-4 as well as Figure 6 The roller brush assembly 30 includes a roller brush 31 and a dust collection box 32. The roller brush 31 is disposed on one side of the filter assembly 20 and can act on the surface of the filter assembly 20 to remove contaminants from the surface of the filter assembly 20. (Refer to...) Figure 13 The dust collection box 32 has a dust collection chamber 320 inside, and a dust collection port 321 communicating with the dust collection chamber 320 is opened on the dust collection box 32. The roller brush 31 is connected to the dust collection box 32 and located at the dust collection port 321. The pollutants carried away from the surface of the filter assembly 20 by the roller brush 31 can enter the dust collection chamber 320 through the dust collection port 321. The cooperative design of the roller brush 31 and the dust collection box 32 allows the pollutants carried away from the surface of the filter assembly 20 by the roller brush 31 to be stored in the dust collection chamber 320, thereby achieving long-term cleaning of the surface of the filter assembly 20 by the roller brush 31.

[0075] In some embodiments, refer to Figures 3-5 The housing 11 has a mounting opening 111 that extends through the housing 11 along its thickness direction, exposing a portion of the surface of the filter assembly 20. (Refer to...) Figure 6 as well as Figures 13-14 The dust collection box 32 has a cover 322 and a box body 323. The cover 322 is detachably connected to the box body 323 to define a dust collection chamber 320. A dust collection port 321 is formed on the box body 323 and can communicate with the mounting port 111. Specifically, when the dust collection assembly 30 is installed on the housing 11, the dust collection port 321 communicates with the mounting port 111. (Refer to...) Figures 3-5 The dust collection assembly 30 is mounted on the housing 11, and the box 323 is embedded in the mounting port 111, so that the dust collection port 321 communicates with the inside of the housing 11. The cover 322 covers the mounting port 111. Since the roller brush 31 is located at the dust collection port 321, and the dust collection port 321 communicates with the inside of the housing 11, one side of the roller brush 31 can be located inside the housing 11, so that the roller brush 31 can interfere with the surface of the filter assembly 20 to remove contaminants from the surface of the filter assembly 20 and ensure the cleaning effect on the surface of the filter assembly 20.

[0076] In some embodiments, refer to Figure 8 The roller brush assembly 30 also includes a roller 33 and a first drive member 34. The roller brush 31 is sleeved on the roller 33, which extends along a first direction X. One end of the roller 33 is connected to the first drive member 34. Under the driving force of the first drive member 34, the roller brush 31 rotates around its own axis following the roller 33. The first drive member 34 is a rotary motor, but it is not limited to this. The rotatable structure of the roller brush 31 can improve the removal effect of the roller brush 31 on the surface of the filter assembly 20, thereby improving the cleaning effect.

[0077] In some embodiments, the rotation direction of the filter assembly 20 is opposite to that of the roller brush 31. This allows the filter assembly 20 and the roller brush 31 to interact relative to each other, improving the cleaning effect of the roller brush 31 on the surface of the filter assembly 20.

[0078] In some embodiments, refer to Figure 13 A second latching part 3231 protrudes from the inner wall of the box body 323, as shown in the reference. Figure 14 A buckle 3222 protrudes from the inner wall of the cover 322. The cover 322 covers the box 323, and the buckle 3222 engages with the second engaging part 3231, thus achieving a detachable connection between the cover 322 and the box 323. In other embodiments, other connection methods can be used between the cover 322 and the box 323, such as bolt connection. The specific method can be selected according to actual usage requirements, as long as a detachable connection is achieved.

[0079] In some embodiments, refer to Figure 6 and Figure 14 A magnetic element 3221 is provided at one end of the cover 322, as shown in the reference. Figure 3 and Figure 4 The housing 11 is provided with a magnetic suction part 114, and the dust collection box 32 is embedded in the first recess 113. The magnetic suction part 3221 is magnetically connected to the magnetic suction part 114, which ensures the stability of the roller brush assembly 30 on the housing 11, while making it easy to remove the roller brush assembly 30 from the housing 11 for subsequent replacement with the vacuuming assembly 40.

[0080] In some embodiments, refer to Figure 4 and Figure 5 A first snap-fit ​​portion 115 is provided on the bottom wall 1131 of the first recess 113 of the housing 11. The box body 323 is snap-fitted to the housing 11 through the first snap-fit ​​portion 115 to realize the detachable connection between the roller brush assembly 30 and the housing 11.

[0081] In some embodiments, refer to Figure 3 and Figure 4 The housing 11 has an outer wall surface 112, on which a first recess 113 is formed. The first recess 113 has a bottom wall 1131, and a mounting opening 111 is formed in the bottom wall 1131. (Refer to...) Figure 2 The dust collection box 32 is inserted into the first recess 113, as shown in the reference. Figure 1 The cover 322 fits over the opening of the first recess 113, and the side of the cover 322 facing away from the box 323 is flush with the outer wall surface 112 of the housing 11. The formation of the first recess 113 on the outer wall surface 112 of the housing 11 provides a space for the dust collection box 32 to be installed on the housing 11, so that the side of the cover 322 facing away from the box 323 is flush with the outer wall surface 112 of the housing 11, thereby improving the overall aesthetics of the air handling unit 100.

[0082] In some embodiments, refer to Figure 9The roller brush assembly 30 also includes a pressing plate 35, which is disposed in the dust collection chamber 320. The pressing plate 35 is adjacent to the roller brush 31, which extends along a first direction X. The pressing plate 35 is movable along the first direction X and can act on the surface of the roller brush 31 away from the filter assembly 20 to concentrate contaminants on the surface of the roller brush 31 to at least one end of the roller brush 31 along the first direction X. The placement of the pressing plate 35 and its movable nature along the first direction X enable it to concentrate contaminants carried away from the surface of the filter assembly 20 by the roller brush 31 to at least one end of the roller brush 31 along the first direction X. This improves the space utilization rate inside the dust collection chamber 320 and allows for timely cleaning of contaminants adhering to the surface of the roller brush 31 away from the filter assembly 20, ensuring a continuous cleaning effect of the roller brush 31 on the filter assembly 20 and guaranteeing long-term cleaning.

[0083] In some embodiments, refer to Figure 9 The roller brush assembly 30 also includes a support shaft 352 and a second driving member (not shown in the figure). The support shaft 352 is disposed in the dust collection chamber 320 and extends along the first direction X. The bristle pressing plate 35 is sleeved on the support shaft 352. One end of the support shaft 352 is connected to the second driving member. The second driving member drives the support shaft 352 to rotate, thereby driving the bristle pressing plate 35 to move along the first direction X. The support shaft 352 is a lead screw, and the bristle pressing plate 35 is threadedly connected to the support shaft 352, so that the rotation of the support shaft 352 can drive the bristle pressing plate 35 to move along the first direction X.

[0084] In some embodiments, refer to Figure 10 The pressing plate 35 has a second recess 351 on one side adjacent to the roller brush 31. The second recess 351 surrounds part of the outer periphery of the roller brush 31 along the circumferential direction. The pressing plate 35 acts on the surface of the roller brush 31 through the second recess 351 to concentrate the pollutants attached to the surface of the roller brush 31 to at least one end of the roller brush 31 along the first direction X, thereby expanding the space of the dust collection chamber 320 for collecting pollutants and improving the space utilization rate of the dust collection chamber 320.

[0085] In some embodiments, refer to Figure 7 The roller brush assembly 30 also includes at least one scraper member 36, which is disposed on at least one side of the roller brush member 31, as shown in the figure. Figure 6The scraper 36 is located at the dust collection port 231 and adjacent to the filter assembly 20. Contaminants on the surface of the filter assembly 20 are carried away by the roller brush 31 and then detached from the surface of the roller brush 31 by the scraper 36. The scraper 36 ensures that contaminants carried away from the surface of the filter assembly 20 by the roller brush 31 are promptly scraped off, guaranteeing the cleaning effect of the roller brush 31 on the surface of the filter assembly 20. In some implementations, two scrapers 36 are used, respectively positioned on opposite sides of the roller brush 31, ensuring effective scraping of the roller brush 31's surface.

[0086] In some embodiments, refer to Figure 11 The scraper component 36 includes a first scraper component 361 and a second scraper component 362, which are respectively located on both sides of the roller brush component 31. Pollutants on the surface of the filter assembly 20 are carried away by the roller brush component 31 and detached from its surface by the first scraper component 361 and the second scraper component 362, enabling timely collection of pollutants and preventing secondary contamination of the filter assembly 20 during rotation. The first scraper component 361 and the second scraper component 362 can be symmetrically or asymmetrically arranged on both sides of the roller brush component 31; the positions of the first scraper component 361 and the second scraper component 362 are not limited here.

[0087] In some embodiments, refer to Figure 11 A first roller brush 311 is attached to the surface of the roller 33. The first roller brush 311 can act on the surface of the filter assembly 20 to remove contaminants from its surface. A first bristle 3611 is attached to the first scraper 361. The first scraper 361 corresponds to a portion of the roller brush 31. The first bristle 3611 is attached to the side of the first scraper 361 near the roller 33, and when the roller 33 rotates, the first bristle 3611 can at least contact the first roller brush 311.

[0088] A second roller brush 312 is also attached to the surface of the roller 33. The second roller brush 312 can act on the surface of the filter assembly 20 to remove contaminants from its surface. A second bristle 3621 is attached to the second scraper 362. The second scraper 362 corresponds to a portion of the roller 33, and the second bristle 3621 is attached to the side of the second scraper 362 closest to the roller 33. When the roller 33 rotates, the second bristle 3621 can at least contact the second roller brush 312. The first bristle 3611 and the second bristle 3621 are used to improve the scraping effect on the contaminants adhering to the first roller brush 311 and the second roller brush 312, thereby improving the cleaning effect of the roller brush assembly 30 on the filter assembly 20.

[0089] In some embodiments, refer to Figure 11 The roller brush assembly 30 also includes a first torsion spring 381, which abuts against the first scraper member 361. Under the torsion of the first torsion spring 381, the first scraper member 361 can resist the roller brush member 31. The roller brush assembly 30 also includes a second torsion spring 382, ​​which abuts against the second scraper member 362. Under the torsion of the second torsion spring 382, ​​the second scraper member 362 can resist the roller brush member 31. When the first scraper 361 is subjected to the torque of the first torsion spring 381, the shape of the first scraper 361 near the roller 33 is adapted to the roller 33; similarly, when the second scraper 362 is subjected to the torque of the second torsion spring 382, ​​the shape of the second scraper 362 near the roller 33 is adapted to the roller 33, for example, both are arc-shaped structures, which can ensure that the roller 33 can generate resistance with the first scraper 361 and the second scraper 362 during rotation, thereby improving the dust collection effect.

[0090] In some embodiments, refer to Figure 11 The roller 33 has a limiting groove 331 on the side near the dust collection box 32, and the dust collection box 32 has a limiting post 332 that matches the limiting groove 331. When the roller 33 reciprocates, the limiting post 332 limits the rotation angle of the roller 33. The setting of the limiting groove 331 and the limiting post 332 can also realize the automatic angle return function. Specifically, when the user stops the cleaning operation of the roller brush assembly 30, the position state of the roller 33 when it stops rotating is random. When the user starts the roller brush assembly 30, the roller 33 starts to rotate. The limiting groove 331 can block the rotation angle of the roller 33 and can calibrate the rotation angle of the roller 33, ensuring that the first roller brush 311 and the second roller brush 312 that are attached to the roller 33 can correspond to the first bristle 3611 and the second bristle 3621 respectively, thereby ensuring the cleaning effect of the roller brush assembly 30.

[0091] In some embodiments, refer to Figure 12 The scraper 36 extends along the first direction X. When the filter assembly 20 rotates, the scraper 36 abuts against the surface of the filter assembly 20 to scrape up the pollutants accumulated on the surface of the filter assembly 20, so that the pollutants can be removed from the filter assembly 20. After the pollutants on the surface of the filter assembly 20 are removed, the impact of pollutants on the air purification effect can be greatly reduced.

[0092] In some embodiments, refer to Figure 12The roller brush assembly 30 also includes a roller brush scraper 363, which scrapes away contaminants remaining on the surface of the roller brush 31 and places the scraped contaminants into the dust collection chamber 320 of the dust collection box 32, thereby greatly reducing the residue of contaminants on the surface of the roller brush 31 and also reducing the possibility of secondary pollution. Specifically, the roller brush scraper 363, the scraper 36, and the roller brush 31 are all located at the dust collection port 321 of the dust collection box 32. The roller brush 31 is located between the roller brush scraper 363 and the scraper 36. The contaminants scraped by the scraper 36 enter the dust collection chamber 320 of the dust collection box 32 under the rotation of the roller brush 31 and are removed from the roller brush 31 by the blocking effect of the roller brush scraper 363.

[0093] It is understood that the above embodiments are merely examples of the roller brush assembly 30. In practical applications, brush plates or other roller brush assemblies 30 capable of cleaning the filter screen may also be used. The structure of the roller brush assembly 30 is not limited here.

[0094] In some embodiments, refer to Figure 6 The box body 323 is provided with a first connector 371, as shown in the reference. Figure 7 A second connector 372 is provided at one end of the roller 33 opposite to the roller brush drive 34 along the first direction X. The second connector 372 is sleeved on the first connector 371 to ensure the installation stability of the roller 33 on the housing 323, the rotational stability of the roller brush 31, and the cleaning effect on the filter assembly 20.

[0095] In some embodiments, refer to Figure 18 and Figure 20 The vacuuming assembly 40 includes a vacuuming component 41, as shown in the reference. Figure 18 The vacuuming component 41 includes a suction end 411 and a dust outlet end 412 connected to each other. The vacuuming component 41 is disposed on one side of the filter assembly 20, with the suction end 411 facing the surface of the filter assembly 20. The vacuuming component 41 can act on the surface of the filter assembly 20 through the suction end 411 to remove contaminants from the surface of the filter assembly 20. The vacuuming component 40 acts on the surface of the filter assembly 20 by suction through the suction component 41, removing contaminants from the surface of the filter assembly 20 without needing to detach from it. Therefore, it employs a different cleaning method than the roller brush assembly 30, ensuring a better cleaning effect on the filter assembly 20.

[0096] In some embodiments, refer to Figures 15-19 The vacuum assembly 40 also includes a housing 42 and a vacuum motor 43. The housing 42 has a connecting wall 421, and the housing 42 can be detachably mounted on the housing 11 via the connecting wall 421. Specifically, see reference... Figure 21 The connecting wall 421 is detachably mounted on the outer wall surface 112 of the housing 11, as shown in the figure. Figure 19The suction end 411 is mounted on the connecting wall 421, and the suction motor 43 is located inside the housing 42. The suction motor 43 can create a negative pressure inside the housing 42, causing the suction component 41 to act on the surface of the filter assembly 20. The cooperation between the suction motor 43 and the housing 42, and the mounting of the suction component 41 on the connecting wall 421 of the housing 42, ensures the installation stability of the suction component 41 and its suction cleaning effect. The placement of the suction motor 43 ensures that the suction component 41 continuously acts on the surface of the filter assembly 20, guaranteeing a cleaning effect on the filter assembly 20.

[0097] It is understood that in other embodiments, the vacuuming assembly 40 may be configured to be flush with the outer wall surface 112 of the housing 11 when it is mounted on the housing 11, and the mounting position and shape of the vacuuming assembly 40 are not limited here.

[0098] In some embodiments, refer to Figures 3-5 The housing 11 has a mounting opening 111 that extends through the housing 11 along its thickness direction, exposing a portion of the surface of the filter assembly 20. (Refer to...) Figure 16 and Figure 18 The connecting wall 421 has an inlet 4211 that communicates with the mounting port 111, as shown in the figure. Figure 19 The suction end 411 of the suction component 41 is covered by the inlet 4211, and the cross-sectional area of ​​the inlet 4211 increases from the end closer to the filter assembly 20 to the end farther away from the filter assembly 20. The suction component 41 generates airflow by drawing air from the inside of the housing 11 through the negative pressure generated by the suction motor 43. The airflow carries contaminants from the surface of the filter assembly 20 and is drawn into the suction component 41 through the inlet 4211. The structural design of the inlet 4211 increasing in cross-sectional area from the end closer to the filter assembly 20 to the end farther away from the filter assembly 20 can amplify the airflow entering the suction component 41 through the inlet 4211, increase the airflow velocity entering the suction component 41, and allow the contaminants carried in the airflow to be quickly discharged through the dust outlet 412, thereby improving the suction cleaning efficiency.

[0099] Understandably, the "narrow slit" design of the inlet 4211 enhances the suction power of the filter assembly 20, ensuring thorough cleaning of the deeper layers of the filter, rather than just the surface. Generally, air handling equipment can have multiple layers of filters; the aforementioned design of the suction assembly 40 allows for deep cleaning of these filters.

[0100] In some embodiments, refer to Figure 18The cross-sectional area of ​​the suction component 41 decreases from the end closer to the filter assembly 20 to the end farther away from the filter assembly 20. This forms a trumpet-shaped structure for the suction component 41. The relatively large cross-sectional area of ​​the suction end 411 of the suction component 41 closer to the filter assembly 20 increases the suction area of ​​the suction component 41 acting on the surface of the filter assembly 20, thereby improving suction efficiency.

[0101] In some embodiments, refer to Figure 19 and Figure 22 The vacuuming assembly 40 also includes a dust collection bag 44, a support member 45, and a first filter 46 disposed on the support member 45. The dust collection bag 44 is connected to the dust outlet end 412 of the vacuuming assembly 41 through a dust collection pipe 441 to collect the contaminants sucked up by the vacuuming assembly 41. The dust collection bag 44 and the vacuuming motor 43 are spaced apart along the first direction X, and the support member 45 is disposed between the vacuuming motor 43 and the dust collection bag 44. The support member 45 can prevent the dust collection bag 44 from being sucked into the air inlet end 431 of the vacuuming motor 43, ensuring the safety and service life of the dust collection bag 44. The first filter 46 can filter the air entering the vacuuming motor 43 through the air inlet end 431, ensuring the service life and safety of the vacuuming motor 43.

[0102] In some embodiments, the first filter element 46 is a high-efficiency particulate air (HEPA) filter.

[0103] In some embodiments, refer to Figure 19 and Figure 22 The vacuuming assembly 40 also includes an exhaust duct 47, which is disposed inside the housing 42, as shown in the reference. Figure 17 The housing 42 has an exhaust port 423. Specifically, the exhaust port 423 is located on the side wall 424 of the housing 42. One end of the exhaust pipe 47 is connected to the exhaust end 432 of the vacuum motor 43, and the other end is connected to the exhaust port 423. The exhaust pipe 47 can discharge the air sucked in by the vacuum motor 43 out of the housing 42 through the exhaust port 423. (Refer to...) Figure 22 The cross-sectional area of ​​the air outlet duct 47 increases from the end near the air outlet 432 to the end near the exhaust port 423, so that the structure of the air outlet duct 47 forms a volute shape, which plays a role in noise reduction and reduces the noise generated by the vacuum cleaner fan 43 during operation.

[0104] In some embodiments, a second filter element (not shown in the figure) is provided at one end of the air outlet 47 near the exhaust port 423. The second filter element can filter the air discharged through the exhaust port 423 to ensure the air filtration effect of the air filtration device 100.

[0105] In some embodiments, the second filter element is a HEPA filter.

[0106] In some embodiments, refer to Figure 18 The housing 42 is connected to a partition 425, which extends along the first direction X to divide the internal space of the housing 42 into two compartments arranged at intervals. The dust collection component 41 is disposed in the compartment adjacent to the filter assembly 20. The dust collection motor 43, dust bag 44, support member 45, first filter 46 and air outlet pipe 47 are disposed in the compartment away from the filter assembly 20. The dust collection pipe 441 is inserted into the partition 425 to connect the dust outlet end 412 of the dust collection component 41 with the dust bag 44.

[0107] In some embodiments, a one-way valve (not shown in the figure) is provided at the connection between the dust collection bag 44 and the dust collection pipe 441 to prevent pollutants entering the dust collection bag 44 from flowing back into the dust collection pipe 441.

[0108] In some embodiments, refer to Figure 5 The filter assembly 20 includes a first filter unit 21 and a second filter unit 22, with the second filter unit 22 surrounding the outside of the first filter unit 21. The roller brush assembly 30 and the vacuuming assembly 40 are configured to be interchangeably mounted on the housing 11, and the roller brush assembly 30 and the vacuuming assembly 40 can respectively act on the surface of the filter assembly 20 to remove contaminants from the surface of the filter assembly 20.

[0109] The roller brush assembly 30 can act on the second filter unit 22 to remove contaminants from its surface. The vacuuming assembly 40 can act on at least the first filter unit 21 to remove contaminants from its surface. It is understood that, in one example, the vacuuming assembly 40 can not only use suction to clean contaminants from the inner first filter unit 21, but also remove surface contaminants from the outer second filter unit 22.

[0110] The air filtration device 100 utilizes the cooperation of the first filter unit 21 and the second filter unit 22 in the filter assembly 20 to filter harmful substances in the outside air entering through the air inlet 101, and then discharges them through the air outlet 102, thus completing air purification. However, outside air may contain large particles such as dust or hair, which may adhere to the surface of the filter assembly 20 during the filtration process, affecting the purification effect. Therefore, the surface of the filter assembly 20 needs to be cleaned regularly to ensure the filtration effect.

[0111] The first filter unit 21 is a HEPA filter, which is a high-efficiency particulate filter used to filter small particulate matter. The second filter unit 22 is a pre-filter (or pre-filter) used to filter large particulate matter. The roller brush assembly 30 acts on the surface of the second filter unit 22 to scrape away large particulate matter adhering to the surface of the second filter unit 22. The vacuuming assembly 40 acts on at least the surface of the first filter unit 21 to remove small particulate matter from the surface of the first filter unit 21. Thus, through the structural design where the roller brush assembly 30 and the vacuuming assembly 40 are interchangeably mounted on the housing 11, cleaning can be achieved for both the outer second filter unit 22 and the inner first filter unit 21, ensuring cleaning effectiveness and guaranteeing the filtration effect and service life of the air filtration device 100.

[0112] In some embodiments, refer to Figure 1 and Figure 15 The air filter device 100 also includes a plug 70, which is electrically connected to the body 10 and is used to receive an external power source to provide electrical energy to the air filter device 100.

[0113] In some embodiments, refer to Figure 23 Along the first direction X, the height of the housing 42 is less than the height of the body 10. This creates a height difference between the housing 42 of the vacuum assembly 40 and the body 10. This height difference can be used to install support pads 50 on the top surface 103 of the body 10 and the top wall 422 of the housing 40. The support pads 50 provide space for pets to play on the air filter device 100 and can also protect the surface of the air filter device 100.

[0114] In some embodiments, refer to Figure 24 The air handling unit 100 also includes a feeding device 60 disposed adjacent to the housing 42. The feeding device 60 is used to provide food to pets. Specifically, the feeding device 60 includes a food storage box 601 and a feeding tray 602. The food storage box 601 is used to supply food (such as cat food or dog food) to the feeding tray 602. The pet can open the food storage box 601 by pressing to feed the pet to the feeding tray 602, or the food storage box 601 can supply food to the feeding tray 602 at regular intervals and in measured quantities. The food storage box 601 and the feeding tray 602 are disposed at intervals on the top wall 422 of the housing 40, thereby expanding the scope of use of the air handling unit 100.

[0115] In some embodiments, refer to Figure 24The air handling unit 100 also includes a water inlet device 61 disposed adjacent to the housing 42. The water inlet device 61 is used to provide drinking water to the pet. Specifically, the water inlet device 61 includes a water tank 612 and a water tray 611. The water tank 612 is used to supply drinking water to the water tray 611. The pet can open the water tank 612 to supply water to the water tray 611 by pressing, or the water tank 612 can supply drinking water to the water tray 611 at regular intervals and in measured amounts. The water tank 612 and the water tray 611 are disposed at intervals on the top wall 422 of the housing 40, thereby expanding the scope of use of the air handling unit 100.

[0116] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations included in the claims. Various modifications and changes can be made to the above embodiments without departing from the scope of this disclosure. Similarly, the various technical features of the above embodiments can be arbitrarily combined to form other embodiments of this application that may not be explicitly described. Therefore, the above embodiments only illustrate several implementations of this application and do not limit the scope of protection of this patent application.
