[0003] This application relates to the field of air purification technology, and in particular to an air purification device. Background Technology

[0004] With the acceleration of industrialization and the continuous advancement of urbanization, air pollution has become an increasingly serious problem, and the decline in air quality has become a global public health concern. Air purification equipment, as an important device for improving indoor air quality, has been widely used. However, during use, the filters of air purification equipment easily accumulate large amounts of dirt, leading to clogging and consequently affecting the overall purification efficiency of the equipment. Utility Model Content

[0005] In view of this, embodiments of this application provide an air purification device that uses the pressing structure of the cleaning component to compress dirt in the collection box, thereby increasing the amount of dirt compressed in the collection box, increasing the capacity utilization of the collection box, reducing the frequency of users emptying the collection box, and facilitating maintenance.

[0006] According to an embodiment of this application, an air purification device is provided, comprising: a main body; a filter screen disposed on the main body; a collection box disposed below the filter screen; a cleaning component configured to be movable relative to the filter screen; and a pressing structure for squeezing dirt in the collection box provided on the side of the cleaning component facing the collection box.

[0007] For example, the pressing structure includes a pressing plate and / or pressing ribs, the pressing plate being arranged parallel to or inclined to the bottom wall of the collection box.

[0008] For example, the air purification device further includes: a drive assembly disposed on the main body; a cleaning assembly including a fixed frame and a comb tooth abutting against a filter screen; the drive assembly being configured to be poweredly connected to the fixed frame to drive the comb tooth to move relative to the filter screen; and a pressing structure disposed on the fixed frame and / or the comb tooth.

[0009] For example, the fixing frame is provided with pressure ribs.

[0010] For example, the comb teeth are provided with a pressure plate.

[0011] For example, the collection box is movably disposed on the main body, and when the cleaning component runs to the bottom, the pressing structure is higher than the upper edge of the rear wall of the collection box at the relative position.

[0012] For example, the upper edge of the rear wall of the collection box is provided with a clearance notch, which is used to avoid the pressing structure running to the bottom.

[0013] For example, the collection box is movably disposed on the main body, and when the cleaning component runs to the bottom, the bottom of the pressing structure is lower than the upper edge of the rear wall of the collection box at the relative position.

[0014] For example, the comb portion has multiple cleaning teeth spaced apart on its edge for contacting the filter screen. The cleaning teeth are used to scrape off dirt from the filter screen. The pressure plate is connected to the comb portion.

[0015] For example, the pressing structure also includes a connecting plate, the first end of which is connected to the pressing plate, and the second end of which is connected to the comb teeth and located above the cleaning teeth.

[0016] For example, the pressing structure also includes support plates located on both sides of the connecting plate, the support plates connecting the connecting plate and the pressing plate.

[0017] For example, the pressure structure is disposed close to the drive assembly, and the pressure plate includes a beveled section, the end of the beveled section near the drive assembly being lower than the end of the beveled section away from the drive assembly.

[0018] For example, the comb teeth are an integral structure; or the comb teeth and the fixing frame are an integral structure; or the comb teeth and the fixing frame are separate structures.

[0019] The air purification device provided in this application embodiment may include a main body, a filter, a collection box, and a cleaning component. By providing a pressing structure on the side of the cleaning component facing the collection box, the dirt inside the collection box is compressed under the action of the pressing structure, thereby increasing the capacity utilization of the collection box. This allows more dirt to be accommodated without increasing the volume of the collection box, extending the emptying cycle of the collection box and reducing the frequency of maintenance for users.

Detailed Implementation

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] like Figures 1 to 23 The embodiments of this application provide an air purification device 10, which includes, but is not limited to, air purifiers, air conditioners, humidifiers and other devices. The embodiments of this application are described using an air purifier as an example.

[0049] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 15 , Figure 17 As shown, the air purification device 10 provided in this application embodiment includes: a main body 100; a filter screen 120 disposed on the main body 100; a collection box 400 disposed below the filter screen 120; a cleaning component 300 configured to be movable relative to the filter screen 120; and a pressing structure 370 for squeezing dirt in the collection box 400 is provided on the side of the cleaning component 300 facing the collection box 400.

[0050] Among them, such as Figure 1 , Figure 2 , Figure 13 and Figure 14As shown, the air purifier 10 may include a main body 100, a filter 120, and a collection box 400. The filter 120 is disposed on the main body 100. Airflow passes through the filter 120, and the filter 120 can filter the airflow, so that the dirt carried in the airflow is filtered by the filter 120 and collected on the filter 120. The air purifier 10 also includes a collection box 400 located below the filter 120.

[0051] like Figure 2 and Figure 14 As shown, by setting a collection box 400 below the filter screen 120, dirt on the filter screen 120 will fall and be collected in the collection box 400 under the action of gravity or the action of the cleaning component 300. Simultaneously, as the cleaning component 300 moves towards the collection box 400, the dirt gradually accumulates and is eventually collected in the collection box 400. This achieves centralized collection of dirt during the cleaning process of the cleaning component 300 on the filter screen 120, preventing secondary contamination and ensuring that the cleaning component 300 remains clean, allowing the equipment to operate continuously and efficiently. Furthermore, the collection box 400 facilitates centralized processing of dirt, making it more convenient for users to clean the collected dirt; simply empty the collection box 400 periodically, making operation convenient.

[0052] Among them, such as Figure 2 , Figure 5 , Figure 6 , Figure 14 As shown, the cleaning component 300 is configured to be movable relative to the filter 140. For example, the cleaning component 300 is movably mounted on the main body 100. Through interference between the cleaning component 300 and the filter 120, such as when the cleaning component 300 abuts against the filter 120, the cleaning component 300 can perform a cleaning operation on the filter 120 during its movement relative to the filter 120, removing at least some of the dirt from the filter 120. This achieves self-cleaning of the filter 120, resulting in higher cleanliness of the filter 120, improving its ventilation, reducing clogging caused by dust and particulate matter accumulation, and thus improving the purification efficiency of the air purifier 10. Furthermore, compared to manually cleaning the filter 120, this design simplifies the user's manual cleaning operation, improves the cleaning experience of the filter 120, reduces the user's maintenance needs, and enhances ease of use and user experience.

[0053] like Figure 2 , Figure 4 , Figure 15 and Figure 17As shown, by providing a pressing structure 370 on the side of the cleaning component 300 facing the collection box 400, the pressing structure 370 compresses the dirt inside the collection box 400, increasing the capacity utilization of the collection box 400. This allows it to hold more dirt without increasing its volume, extending the emptying cycle of the collection box 400 and reducing the frequency of maintenance for users. Simultaneously, the pressing structure 370 reduces the loose accumulation of dirt inside the collection box 400, ensuring it is compacted and reduced, decreasing the possibility of dirt scattering when emptying the collection box 400 and further reducing secondary pollution.

[0054] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 15 and Figure 17 As shown, in some embodiments, the pressing structure 370 includes a pressing plate 371 and / or pressing ribs 313. That is, the pressing structure 370 may include a pressing plate 371, or it may include pressing ribs 313, or it may include both a pressing plate 371 and pressing ribs 313. This allows for the fulfillment of different structural requirements for the pressing structure 370 and facilitates its implementation. Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments, the pressing structure 370 includes a pressing plate 371, which is parallel to or inclined to the bottom wall of the collection box 400. Specifically, the pressing plate 371 can be located at the bottom end of the pressing structure 370. Since the bottom end of the pressing structure 370 preferentially and directly contacts the dirt in the collection box 400, by setting the pressing plate 371 parallel to the bottom wall of the collection box 400, or setting the pressing plate 371 inclined to the bottom wall of the collection box 400, the projected area of ​​the pressing plate 371 on the plane where the bottom wall of the collection box 400 is located is larger, which increases the contact area between the pressing structure 370 and the dirt in the collection box 400. This can improve the compression of the dirt in the collection box 400, which is beneficial to further increase the capacity utilization of the collection box 400, so that more dirt can be accommodated without increasing the volume of the collection box 400. At the same time, this allows the waste inside the collection box 400 to be further compacted, effectively reducing the phenomenon of loose accumulation of waste inside the collection box 400, reducing the possibility of waste scattering when emptying the collection box 400, further reducing secondary pollution of waste, reducing the frequency of users emptying the collection box 400, and improving the user experience of emptying the collection box 400.

[0055] Furthermore, such as Figure 2 and Figure 14 As shown, the collection box 400 is movably disposed on the main body 100. The collection box 400 can be movably connected to the main body 100 via a pull-out method, a snap-fit ​​method, a plug-in method, or a magnetic attraction method. It can be understood that the collection box 400 can be detachably connected to the main body 100, meaning the collection box 400 and the main body 100 can be separated. This facilitates the assembly and disassembly of the collection box 400 from the main body 100, making it convenient to handle the dirt inside the collection box 400. For example, the collection box 400 can be removed from the main body 100, and the collected dirt inside can be emptied. This operation is convenient and also facilitates the cleaning of the collection box 400. It can be understood that in some examples, the collection box 400 can be movably connected to the main body 100, causing their relative positions to change; however, they can remain inseparable.

[0056] Furthermore, the collection box 400 is removably mounted on the main body 100, simplifying the connection structure. The collection box 400 can be easily detached from the main body 100 via a simple pull-out mechanism, making operation simple and convenient. Simultaneously, this design improves the sealing performance of the collection box 400 when it is installed on the main body 100, reducing the possibility of secondary pollution caused by spillage of contaminants from the collection box 400 into the external environment. It also enhances the aesthetic appeal and tidiness of the air purification device 10.

[0057] Specifically, the collection box 400 can be horizontally pulled out of the main body 100 so that it can be located below the cleaning component 300, effectively containing dirt. Figure 2 As shown, the collection box 400 is slidably mounted on the main body 100 in the front-to-back direction, allowing for easy assembly and disassembly of the collection box 400 from the main body 100 by simply pulling it out in this direction. The front-to-back direction can be... Figure 2 As indicated by the arrow Y in the diagram.

[0058] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 14 As shown, in some embodiments, the air purification device 10 further includes: a drive assembly 200 disposed on the main body 100; a cleaning assembly 300 including a fixed frame 310 and a comb tooth 320 connected to each other, the comb tooth 320 abutting against the filter screen 120, the drive assembly 200 being configured to be poweredly connected to the fixed frame 310 to drive the comb tooth 320 to move relative to the filter screen 120, and a pressing structure 370 disposed on the fixed frame 310 and / or the comb tooth 320.

[0059] In the air purification device 10 provided in this embodiment, the comb teeth 320 of the cleaning component 300 abuts against the filter screen 120, and the fixing frame 310 of the cleaning component 300 is poweredly connected to the drive component 200. In this way, when the drive component 200 moves, the fixing frame 310 can drive the comb teeth 320 to move relative to the filter screen 120. During the movement, the comb teeth 320 abuts against the filter screen 120, so that the comb teeth 320 can perform a cleaning operation on the filter screen 120 during the movement relative to the filter screen 120, removing at least some of the dirt on the filter screen 120, thereby realizing the self-cleaning operation of the filter screen 120, making the filter screen 120 have high cleanliness, which is beneficial to improving the ventilation of the filter screen 120.

[0060] The pressing structure 370 can be set on the fixed frame 310, or it can be set on the comb tooth 320, or it can be set on both the fixed frame 310 and the comb tooth 320. This can meet the needs of different setting positions of the pressing structure 370. It can be understood that the pressing structure 370 set on the fixed frame 310 may include a pressing plate 371 and / or a pressing rib 313, and the pressing structure 370 set on the comb tooth 320 may include a pressing plate 371 and / or a pressing rib 313.

[0061] like Figure 15 and Figure 17 As shown, in some embodiments, the mounting bracket 310 is provided with pressure ribs 313. Specifically, the mounting bracket 310 has pressure ribs 313 on the side facing the collection box 400. When dirt on the filter screen 120 is collected into the collection box 400, the pressure ribs 313 can compress the dirt inside the collection box 400. This compression helps to compress the dirt, thereby increasing the capacity utilization of the collection box 400. This means that more dirt can be accommodated without increasing the volume of the collection box 400, extending the emptying cycle of the collection box 400 and reducing the frequency of user maintenance. Furthermore, the design of the pressure ribs 313 helps prevent loose accumulation of dirt inside the collection box 400, reducing the likelihood of dirt scattering when emptying the collection box 400. This design not only improves the efficiency of the air purifier 10 but also enhances the user experience, making equipment maintenance simpler and cleaner.

[0062] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, the comb tooth 320 is provided with a pressure plate 371, that is, a pressure plate 371 is provided on the side of the comb tooth 320 facing the collection box 400. The pressure plate 371 is used to squeeze the dirt in the collection box 400, so that the dirt in the dust box is compressed under the action of the pressure plate 371, thereby increasing the capacity utilization of the collection box 400. This allows more dirt to be accommodated without increasing the volume of the collection box 400, extending the emptying cycle of the collection box 400 and reducing the frequency of maintenance by the user. At the same time, the setting of the pressure plate 371 can reduce the loose accumulation of dirt in the collection box 400, making the dirt more compacted in the collection box 400, reducing the possibility of dirt scattering when emptying the collection box 400, and further reducing secondary pollution from dirt.

[0063] It is understandable that, such as Figure 2 , Figure 4 , Figure 12 , Figure 14 As shown, the comb tooth 320 can reciprocate relative to the filter screen 120, such as the comb tooth 320 being able to move up and down relative to the filter screen 120 in the vertical direction. The vertical direction can be as follows: Figure 2 As indicated by arrow Z in the diagram. The comb tooth 320 can operate to both the bottom and top ends, meaning the position of the comb tooth 320 relative to the filter screen 120 includes both extreme positions close to and far from the collection box 400. Specifically, Figure 2 and Figure 4 The image shows the comb tooth 320 in its extreme position relative to the filter screen 120, close to the collection box 400. At this point, the comb tooth 320 has reached its bottom position. Figure 12 and Figure 14 The diagram shows the comb teeth 320 at its extreme position relative to the filter screen 120, far from the collection box 400, at which point the comb teeth 320 has reached its top position. Specifically, when the comb teeth 320 reaches its bottom position, that is, when the comb teeth 320 has reached its lowest position relative to the filter screen 120 in the direction closer to the collection box 400, as shown... Figure 2 and Figure 4 As shown, when the comb tooth 320 can no longer move towards the collection box 400, it indicates that the comb tooth 320 has reached its limit position relative to the filter screen 120, close to the collection box 400. When the comb tooth 320 reaches its top, that is, when the comb tooth 320 has reached its highest position relative to the filter screen 120, away from the collection box 400, as... Figure 12As shown, when the comb tooth 320 can no longer move away from the collection box 400, it indicates that the comb tooth 320 has reached its extreme position relative to the filter screen 120, away from the collection box 400. In practical applications, the comb tooth 320 switches between the top and bottom ends, that is, the comb tooth 320 moves relative to the filter screen 120 and alternates between the extreme position near the collection box 400 and the extreme position far from the collection box 400, so as to realize the reciprocating motion of the comb tooth 320 relative to the filter screen 120.

[0064] Specifically, when the comb tooth 320 moves downward relative to the filter screen 120, that is, when the comb tooth 320 moves from the extreme position away from the collection box 400 to the extreme position close to the collection box 400, that is, when the comb tooth 320 moves to the bottom, the comb tooth 320 abuts and interferes with the filter screen 120 to achieve the cleaning operation of the filter screen 120, and collects the scraped dirt in the collection box 400, and uses the pressing structure 370 to press the dirt in the collection box 400. When the comb tooth 320 moves to the limit position near the collection box 400, that is, when the comb tooth 320 moves to the bottom, the comb tooth 320 will move upward for a short time. For a short time, the comb tooth 320 will move away from the limit position of the collection box 400, that is, the comb tooth 320 will move to the top. When the comb tooth 320 reaches the limit position away from the collection box 400, that is, when the comb tooth 320 moves to the top, it will continue to move towards the position near the collection box 400 for a short time, and so on.

[0065] like Figure 4 As shown, in some embodiments, when the cleaning component 300 is running to the bottom, that is, when the comb tooth 320 is running to the bottom, the pressing structure 370 is higher than the upper edge of the rear wall of the collection box 400 at the relative position, wherein the pressing structure 370 includes a pressing plate 371 and / or pressing ribs 313.

[0066] In other words, when the cleaning component 300 reaches its bottom position, that is, when the comb tooth 320 moves to its limit position near the collection box 400 relative to the filter screen 120, the pressure plate 371 and / or pressure ribs 313 are located above the upper edge of the rear wall of the collection box 400 at the relative position. This ensures that the pressure plate 371 and / or pressure ribs 313 do not obstruct the collection box 400 from moving relative to the main body 100 to a preset position. The preset position can be to pull the collection box 400 out of the main body 100 for easy emptying of the collection box 400, or to move the collection box 400 to another position relative to the main body 100 for easy handling of the dirt in the collection box 400. In other words, the pressure structure 370 does not affect the use of the equipment. Users can move the collection box 400 to the preset position at any time, such as pulling the collection box 400 out of the main body 100, improving the convenience of user operation and user satisfaction.

[0067] like Figure 4 As shown, in the above embodiment, the upper edge of the rear wall of the collection box 400 is provided with an avoidance notch 401, which is used to avoid the pressure structure 370 when it reaches the bottom. The avoidance notch 401 allows the collection box 400 to avoid the pressure structure 370 when the comb tooth 320 reaches the bottom, i.e., when the comb tooth 320 is at its extreme position close to the collection box 400. This reduces the possibility of interference between the collection box 400 and the pressure plate 371 and / or pressure ribs 313 during the process of moving to the preset position. Therefore, the collection box 400 can move smoothly to the preset position and detach smoothly from the main body 100, ensuring that the pressure structure 370 does not affect the assembly or disassembly of the collection box 400. This allows the user to pull the collection box 400 out of the main body 100 at any time, improving the convenience of user operation and increasing user satisfaction. Meanwhile, this configuration allows the pressure plate 371 and / or pressure ribs 313 to extend as far into the collection box 400 as possible when the comb tooth 320 reaches the bottom. This minimizes the distance between the pressure plate 371 and / or pressure ribs 313 and the bottom wall of the collection box 400. Consequently, the pressure plate 371 and / or pressure ribs 313 can compress the waste in the collection box 400 more tightly, further increasing the amount of waste compressed. This is beneficial for increasing the capacity utilization of the collection box 400, allowing it to hold more waste without increasing its volume, reducing the frequency of emptying the collection box 400, and facilitating maintenance.

[0068] like Figure 2As shown, in some embodiments, when the cleaning assembly 300 is at its bottom, i.e., when the comb tooth 320 is at its bottom, the bottom of the pressing structure 370 is lower than the upper edge of the rear wall of the collection box 400 at the opposite position. The pressing structure 370 includes a pressing plate 371 and / or pressing ribs 313.

[0069] In other words, when the cleaning component 300 reaches its bottom position, that is, when the comb 320 moves to the limit position near the collection box 400 relative to the filter screen 120, the pressure plate 371 and / or pressure ribs 313 will prevent the collection box 400 from moving smoothly to the preset position relative to the main body 100. For example, since the bottom of the pressure plate 371 and / or pressure ribs 313 is lower than the upper edge of the rear wall of the collection box 400 at the relative position, when the collection box 400 is pulled horizontally, the upper edge of the rear wall of the collection box 400 will interfere with the pressure plate 371 and / or pressure ribs 313, and the pressure plate 371 and / or pressure ribs 313 will prevent the collection box 400 from detaching from the main body 100. It is understandable that when the comb tooth 320 moves to the bottom, it will move to the top in a short time, so that the pressure plate 371 and / or pressure rib 313 can be higher than the upper edge of the rear wall of the collection box 400 in a short time. This allows the collection box 400 to move smoothly to the preset position relative to the main body 100, such as the collection box 400 being able to detach smoothly from the main body 100. In other words, this situation has little impact on the user. Meanwhile, this design allows for a smaller distance between the bottom of the pressure plate 371 and / or the pressure ribs 313 and the bottom wall of the collection box 400 when the comb tooth 320 reaches its bottom. This allows the pressure plate 371 and / or the pressure ribs 313 to extend deeper into the collection box 400. Consequently, the pressure plate 371 and / or the pressure ribs 313 can compress the waste inside the collection box 400 more tightly, further increasing the amount of waste compressed. This is beneficial for increasing the capacity utilization of the collection box 400, allowing it to hold more waste without increasing its volume, reducing the frequency of emptying the collection box 400, and facilitating maintenance.

[0070] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the comb member 320 also includes a comb tooth portion 360, the bottom edge of which is configured to abut against the filter screen 120, thereby scraping off dirt from the filter screen 120 to achieve a cleaning operation of the filter screen 120.

[0071] The pressing structure 370 is located on the side of the comb tooth section 360 away from the filter screen 120, so that the pressing structure 370 will not obstruct the smooth and reliable contact between the comb tooth section 360 and the filter screen 120, so that the comb tooth section 360 has a good cleaning effect.

[0072] like Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments, the comb portion 360, which abuts against the filter screen 120, has multiple cleaning teeth 322 spaced apart on its edge. These cleaning teeth 322 scrape away dirt from the filter screen 120. The pressure plate 371 is connected to the comb portion 360. The scraping action of the cleaning teeth 322 improves the cleaning efficiency and effectiveness of the cleaning assembly 300 on the filter screen 120, further enhancing the cleanliness of the filter screen 120. Simultaneously, the arrangement of the cleaning teeth 322 reduces the possibility of the comb portion 320 itself becoming entangled with hair. If the cleaning teeth 322 are arranged in rows, the spaced arrangement of the cleaning teeth 322 reduces the risk of long, thin dirt such as hair becoming entangled between the teeth during cleaning, reducing the possibility of performance degradation or equipment failure due to entanglement of the cleaning teeth 322. This allows the equipment to maintain efficient filtration and cleaning effects even after prolonged operation, providing users with a more reliable and low-maintenance user experience. Specifically, cleaning teeth 322 can be arranged at the bottom edge of the comb teeth 360, and the cleaning teeth 322 can abut against the filter screen 120 to scrape off the dirt on the filter screen 120.

[0073] Furthermore, the pressure plate 371 is connected to the comb teeth 360. It can be understood that the pressure plate 371 can be directly connected to the comb teeth 360, or indirectly connected to the comb teeth 360 through other components. The pressure plate 371 is located below the cleaning teeth 322, allowing it to extend into the collection box 400 before the cleaning assembly 300 moves towards it. This compresses the dirt inside the collection box 400, increasing its capacity utilization. This provides space for the cleaning teeth 322, located behind the pressure plate 371 in the direction of movement, to scrape away dirt as they move towards the collection box 400. This allows the collection box 400 to hold more dirt and reduces the possibility of overflow. This ensures efficient use of the space within the collection box 400, further improving its capacity utilization, reducing the frequency of emptying the collection box, and facilitating maintenance.

[0074] Furthermore, such as Figure 8As shown, the tips of the cleaning teeth 322 are designed with a rounded arc structure 323, meaning the cleaning teeth 322 have a rounded tooth structure. This design makes the outer edge of the cleaning teeth 322 a relatively smooth curved surface structure, which reduces the possibility of the sharp corners of the outer edge of the cleaning teeth 322 scratching the user and improving user safety. At the same time, making the tips of the cleaning teeth 322 into a rounded arc structure 323 allows the tips of the arc structure 323 to penetrate into the interior of hair clumps and other accumulated dirt, effectively scraping away hair and other dirt, improving the cleaning effect of dirt, and thus improving the cleanliness of the filter screen 120. Meanwhile, this design allows the cleaning teeth 322 to contact the filter screen 120 through the arc structure 323. That is, the outer edge of the cleaning teeth 322 in contact with the filter screen 120 can be a relatively smooth curved surface. This reduces the possibility of the cleaning teeth 322 having sharp corners that could scratch or abrade the filter screen 120, thus reducing wear and tear and extending the lifespan of the filter screen 120. Overall, this design ensures that the cleaning teeth 322 provide excellent cleaning performance while preventing scratches and wear on the filter screen, improving user safety and extending the lifespan of the filter screen 120.

[0075] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 As shown, the pressing structure also includes a connecting plate 372. The first end of the connecting plate 372 is connected to the pressing plate 371, and the second end of the connecting plate 372 is connected to the comb tooth portion 360 and located above the cleaning teeth 322. The connecting plate 372 connects the pressing plate 371 and the comb tooth portion 360, ensuring a reliable connection between the pressing structure 370 and the comb tooth portion 360. Furthermore, by bending the connecting plate 372 and the pressing plate 371, the pressing structure 370 can form a frame structure. This allows the pressing plate 371 to be arranged parallel to or inclined to the bottom wall of the collection box 400, resulting in a larger contact area between the pressing plate 371 and the dirt inside the collection box 400. By positioning the second end of the connecting plate 372 above the cleaning teeth 322, the pressing structure 370 and the cleaning teeth 322 will not interfere with each other, preventing the pressing structure 370 from clogging the cleaning teeth 322, thus ensuring that the cleaning teeth 322 have good cleaning and anti-tangling effects.

[0076] Furthermore, the connecting plate 372 is connected to the pressure plate 371 on the side near the filter screen 120, so that the entire pressure structure is located on the side of the cleaning teeth 322 away from the filter screen 120. This design ensures that the connecting plate 372 does not obstruct the smooth contact between the cleaning teeth 322 and the filter screen 120, so that the cleaning teeth 322 have a good cleaning effect. At the same time, the connecting plate 372 can prevent the dirt on the filter screen 120 from falling onto the pressure plate 371, so that the pressure structure 370 has good cleanability, and the dirt on the filter screen 120 can fall into the collection box 400 in a more concentrated manner, reducing the possibility of secondary pollution from dirt.

[0077] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the pressing structure also includes support plates 373 located on both sides of the connecting plate 372, which connect the pressing plate 371 and the connecting plate 372. The support plates 373 improve the reliability and stability of the connection between the connecting plate 372 and the pressing plate 371, enhance the strength of the pressing structure 370, and enable the pressing plate 371 to have good ability to squeeze out dirt and be less prone to damage, thus extending the service life of the pressing structure 370 and improving the overall service life of the cleaning assembly 300.

[0078] The pressing structure has an opening on the side away from the filter screen 120. Because the opening is positioned away from the filter screen 120, it reduces the likelihood of dirt on the filter screen 120 falling onto the pressing plate 371, thus improving the cleanliness of the pressing structure 370. This allows dirt on the filter screen 120 to fall more concentratedly into the collection box 400, reducing the possibility of secondary contamination. Simultaneously, the opening reduces the material required for the pressing structure, helping to save costs.

[0079] Specifically, the connecting plate 372 of the pressing structure 370 is arranged opposite to the cleaning tooth 322, and there is a gap between the connecting plate 372 and the cleaning tooth 322. The gap provides a certain flow space for the dirt scraped by the cleaning tooth 322, reducing the phenomenon of dirt clogging or wrapping around the cleaning tooth 322, so that the cleaning tooth 322 can maintain a clean state and has a good ability to scrape dirt, thereby improving the cleaning efficiency and cleaning effect of the cleaning component 300.

[0080] In some embodiments, such as Figure 2 As shown, the drive assembly 200 drives the comb tooth 320 to move vertically relative to the filter screen 120 via the fixing frame 310. The vertical direction is as follows: Figure 2 As shown by arrow Z, the cleaning teeth 322 are arranged in rows along the horizontal direction, and the horizontal direction can be as follows: Figure 2As indicated by arrow X in the diagram. Thus, during the vertical relative movement of the comb teeth 320 and the filter screen 120, the horizontally arranged rows of cleaning teeth 322 contact the filter screen 120, providing a large contact area that comprehensively covers the entire surface area of ​​the filter screen 120. This effectively removes dirt from the filter screen 120, resulting in high cleaning efficiency and effectiveness. It is understood that in some examples, the drive assembly 200, via the mounting bracket 310, can drive the comb teeth 320 to move relative to the filter screen 120 in a horizontal or other direction, and the first cleaning teeth 322 can be arranged in rows in a vertical or other direction.

[0081] Understandable, Figure 2 The arrow Z in the image can also represent the height direction of filter 120. Figure 2 The arrow X in the image can also represent the width direction of filter 120. Figure 2 Y in the text can also represent the thickness direction of filter 120. Its cleaning principle is the same as that described above, and will not be repeated here.

[0082] In some embodiments, such as Figure 9 , Figure 10 , Figure 11 As shown, the comb tooth 320 also includes a connecting portion 361 and an elastic connecting portion 362. The connecting portion 361 is connected to the fixing frame 310, and the elastic connecting portion 362 connects the top of the comb tooth 360 and the connecting portion 361. The elastic connecting portion 362 is configured to generate elastic deformation under the support of the filter screen 120 so that the comb tooth 360 supports the filter screen 120.

[0083] Because the filter screen 120 has dimensional tolerances in the thickness direction, the elastic connecting part 362 ensures that the comb teeth 360 of the comb component 320 and the filter screen 120 are always kept in a pressed state. When external force is applied to the cleaning component 300, such as when the comb teeth 360 abuts against the filter screen 120, the elastic connecting part 362 can absorb and buffer these forces, thus protecting the comb teeth 360 and the filter screen 120 and ensuring they remain pressed together. This reduces the possibility of damage to the comb teeth 360 and other components, resulting in a better cleaning effect for the comb component 320 and extending the service life of the cleaning component 300. Simultaneously, this design prevents excessive friction between the comb teeth 360 and the filter screen 120, thus avoiding excessive noise and overload on the drive component 200, improving user comfort and the stability of the drive component 200 operation.

[0084] Furthermore, to ensure reliable contact between the comb teeth 360 and the filter screen 120, a pre-pressure amount is typically set for the comb teeth 360. However, in practical applications, the dimensional tolerance of the filter screen 120 in the thickness direction increases, potentially leading to a failure to reliably press the comb teeth 360 and the filter screen 120 together. Therefore, an elastic connecting part 362 is provided. This elastic connecting part 362 has good deformation capacity, which, combined with the pre-pressure amount of the comb teeth 360, ensures a tight fit between the comb teeth 360 and the filter screen 120, improving cleaning efficiency. Simultaneously, it prevents excessive friction between the comb teeth 360 and the filter screen 120, thus avoiding excessive noise and overload on the drive assembly 200, improving user comfort and operational stability of the drive assembly 200.

[0085] In the above embodiments, the elastic connecting portion 362 has a plate-like structure, and the thickness of the elastic connecting portion 362 is as follows: Figure 11 As shown in D0, the thickness of the elastic connecting portion 362 ranges from 0.8 mm to 1.2 mm. The plate-like elastic connecting portion 362 has good elastic deformation capability and a large connection area, which enables reliable connection between the comb tooth portion 360 and the connecting portion 361 through the elastic connecting portion 362, thereby improving the overall reliability of the comb tooth component 320.

[0086] By reasonably setting the thickness range of the elastic connecting part 362, the elastic deformation capability of the elastic connecting part 362 can be controlled within a certain range. This deformation capability, combined with the pre-compression amount of the comb tooth part 360, can keep the comb tooth part 360 and the filter screen 120 in close contact, achieving better cleaning operation. At the same time, it prevents the friction between the comb tooth part 360 and the filter screen 120 from being too great, thus avoiding excessive noise and excessive load on the drive component 200, improving user comfort and the stability of the drive component 200 operation. Specifically, the thickness D0 of the elastic connecting part 362 can be any dimension from 0.8mm, 0.9mm, 1.0mm, 1.1mm, 1.2mm, or 0.8mm to 1.2mm.

[0087] Furthermore, by setting the elastic connecting part 362 and the connecting part 361 at an angle, that is, by bending the elastic connecting part 362 and the connecting part 361, when the comb tooth part 360 contacts the filter screen 120 and is subjected to force, deformation easily occurs at the bending point of the elastic connecting part 362 and the connecting part 361, causing the angle between the elastic connecting part 362 and the connecting part 361 to change. This adjusts the fit between the comb tooth part 360 and the filter screen 120, ensuring that the comb tooth part 360 and the filter screen 120 remain in close contact, and preventing excessive friction between them from causing excessive noise or excessive load on the drive component 200.

[0088] Furthermore, the elastic connecting portion 362 and the comb tooth portion 360 are set at an angle, that is, the elastic connecting portion 362 and the comb tooth portion 360 are bent. Therefore, when the comb tooth portion 360 contacts the filter screen 120 and is subjected to force, deformation easily occurs at the bend of the elastic connecting portion 362 and the comb tooth portion 360, which causes the angle between the elastic connecting portion 362 and the connecting portion 361 to change. This adjusts the fit between the comb tooth portion 360 and the filter screen 120, so that the comb tooth portion 360 and the filter screen 120 remain in a tight fit, and the friction between the two is not too great, which would cause excessive noise and excessive load on the drive component 200.

[0089] It is understood that the elastic connecting part 362 may be set at an angle to the connecting part 361, or the elastic connecting part 362 may be set at an angle to the comb part 360, or one end of the elastic connecting part 362 may be set at an angle to the connecting part 361, while the other end of the elastic connecting part 362 may be set at an angle to the comb part 360.

[0090] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 As shown, two comb teeth 320 are connected to opposite sides of the fixed frame 310, meaning the fixed frame 310 is located between the two comb teeth 320. Thus, by connecting the fixed frame 310 in the middle to the drive assembly 200, the two comb teeth 320 can be moved relative to the filter screen 120. In other words, by using one drive assembly 200 connected to the fixed frame 310 in the middle, the entire cleaning assembly 300 can be driven to move relative to the filter screen 120. Compared to using two drive assemblies 200 connected to the cleaning assembly 300 from both sides to drive the entire cleaning assembly 300 relative to the filter screen 120, this simplifies the number of drive assemblies 200, saves costs, and meets the design requirements of a compact structure and small size for the air purification device 10, making it suitable for widespread application.

[0091] In some embodiments, the air purifier 10 has an air inlet 110 on its main body 100, and the filter 120 is connected to the air inlet 110. The air inlet 110 is located at the center of the filter 120, so most of the dirt such as hair filtered by the filter 120 will be concentrated in the middle of the filter 120. That is to say, there is more dirt in the middle of the collection box 400, and the drive assembly 200 is usually connected to the middle of the filter 120.

[0092] Therefore, by setting the pressing structure 370 close to the drive assembly 200, that is, setting the pressing structure 370 close to the middle of the filter screen 120, the pressing plate 371 includes an inclined section 374. The end of the inclined section 374 near the drive assembly 200 is lower than the end of the inclined section 374 away from the drive assembly 200, so that the pressing plate 371 can better press down the more and higher dirt in the middle of the collection box 400 by using the inclined section 374, reducing the situation of excessive dirt in the middle of the collection box 400 and local overflow, increasing the amount of dirt compressed in the collection box 400, which is conducive to further increasing the capacity utilization rate of the collection box 400.

[0093] In some embodiments, such as Figure 10 As shown, the comb tooth component 320 has a one-piece structure, integrating components such as the pressure structure 370, comb teeth 360, connecting part 361, and elastic connecting part 362 into a single unit. This design improves the structural strength and stability of the comb tooth component 320, eliminates loosening or misalignment problems that may occur due to the connection between multiple independent parts, simplifies the manufacturing process, reduces assembly steps and time, and helps reduce production costs. Furthermore, the one-piece structure reduces potential failure points, improving the durability and reliability of the comb tooth component 320. Since there are no redundant connecting parts, the comb tooth component 320 can transmit force and motion more efficiently during operation, improving its working efficiency.

[0094] In some embodiments, such as Figure 5 As shown, the comb tooth component 320 and the fixing frame 310 are separate structures, and the comb tooth component 320 and the fixing frame 310 are configured for detachable connection. This design facilitates the assembly and disassembly of the comb tooth component 320 and the fixing frame 310, allowing for individual repair or replacement of the comb tooth component 320 and the fixing frame 310, thus improving repair efficiency and saving repair costs. Specifically, the comb tooth component 320 and the fixing frame 310 can be detachably connected using at least one of the following methods: bolt structure, snap-fit ​​structure, plug-in structure, tenon structure, and magnetic structure. Specifically, as... Figure 5 As shown, the cleaning assembly also includes connecting screws 380, and each comb tooth 320 is fixed to the mounting bracket 310 by the connecting screws 380, making it easy to assemble and disassemble. Figure 5 The comb tooth 320 and the retainer 310 are shown to be connected by connecting screws 380.

[0095] In some embodiments, such as Figure 6As shown, the comb teeth 320 and the fixing frame 310 are an integral structure. This design improves the structural strength and stability of the cleaning assembly 300, eliminates loosening or misalignment problems that may occur due to the connection between multiple independent parts, and simplifies the manufacturing process, reducing assembly steps and time, thus lowering production costs. Furthermore, the integral structure reduces potential failure points, improving the durability and reliability of the cleaning assembly 300. Without redundant connecting parts, the cleaning assembly 300 can transmit force and motion more efficiently during operation, improving its working efficiency.

[0096] In some embodiments, such as Figure 2 As shown, the air purification device 10 also includes a transmission component 250, which is disposed on the main body 100 and connected to the drive component 200. The transmission component 250 is threadedly driven to the cleaning component 300, and similarly, to the fixing frame 310. This threaded drive design converts rotational motion into linear motion. Driving the cleaning component 300 via a threaded drive provides higher precision, ensuring stable speed and direction during transmission without slippage or deviation. The precision of the threaded drive allows the cleaning component 300 to move in minute steps, achieving a more comprehensive and uniform cleaning of the filter 120. This allows the cleaning component 300 to move smoothly and precisely along the surface of the filter 120 under the drive of the transmission component 250. This design not only improves the stability and reliability of the cleaning process but also effectively reduces the problems of uneven cleaning and damage to the filter 120 that may occur during manual cleaning, making it suitable for widespread application.

[0097] In some implementations, such as Figure 2 As shown, the transmission assembly 250 includes a transmission rod rotatably mounted on the main body 100. The transmission rod can be a screw, such as... Figure 5 As shown, the cleaning component 300 has a threaded hole 214. The cleaning component 300 is fitted onto the screw through the threaded hole 214 on the fixing bracket 310 and is threadedly driven by the screw. Under the drive of the screw, the cleaning component 300 can move relative to the filter screen 120 along the axial direction of the screw and clean the filter screen 120. The transmission component 250 is designed to include a rotatable screw. The cleaning component 300 has a threaded hole 214 that matches the screw, so that the cleaning component 300 can be connected to the transmission rod through threaded transmission. When the transmission rod rotates, the cleaning component 300 moves along the axial direction of the transmission rod under the action of the thread. This design allows the cleaning component 300 to effectively perform linear movement under the drive of the transmission rod, thereby performing a cleaning operation relative to the filter screen 120.

[0098] In some implementations, such as Figure 2 and Figure 3 As shown, the drive assembly 200 includes a drive member 210, a drive gear 220 connected to the drive member 210, and a transmission gear 230 that is pulsatorically connected to the drive gear 220. The screw has a transmission end, and the transmission gear 230 is pulsatorically connected to the transmission end to drive the rotation of the screw.

[0099] The drive assembly 200 comprises a drive element 210, a drive gear 220, and a transmission gear 230. The drive element 210 can be a motor or other type of power device, transmitting power to the transmission gear 230 via the drive gear 220. The transmission gear 230 is further connected to the transmission end of the screw, thereby driving the screw's rotation. This design effectively transmits the power of the drive element 210 to the screw through a gear transmission system, enabling the screw to rotate stably and efficiently. This structure not only improves the efficiency of the transmission system but also makes the operation of the entire device more precise and reliable.

[0100] Specifically, such as Figure 3 As shown, in some embodiments, the drive assembly 200 further includes at least one transition gear 240 that is transmissionally connected between the drive gear 220 and the transmission gear 230. Thus, the power of the drive member 210 is transmitted to the screw via the drive gear 220, transition gear 240, and transmission gear 230 to drive the screw to rotate. The arrangement of the drive gear 220, transition gear 240, and transmission gear 230 can achieve speed regulation. For example, by reasonably setting the number of teeth on the drive gear 220, transition gear 240, and transmission gear 230, and appropriately setting the transmission ratio, the screw can run smoothly at a suitable speed, thereby improving the smoothness of the cleaning assembly 300's operation.

[0101] In some implementations, such as Figure 1 As shown, the main body 100 includes a detachably connected front cover 101 and a housing 102. The housing 102 can be detachably connected to the front cover 101 through snap-fit, threaded connection, interference fit, or other means. The housing 102 and / or the front cover 101 form an air inlet. For example, the front cover 101 and the housing 102, when connected, together enclose an air inlet communicating with the filter 120; or, the air inlet is directly opened on the front cover 101; or, the air inlet is directly opened on the housing 102, etc. These are merely illustrative examples and do not indicate or imply that the air inlet can only be set in this way. Specifically, the filter 120 is located on the housing 102, the drive assembly 200 is located on the housing 102, and the transmission assembly 250 is located on the housing 102.

[0102] Please see Figure 13 , Figure 14 and Figure 15In some embodiments, this application provides an air purification device 10, which includes a main body 100, a drive assembly 200, and a cleaning assembly 300. The main body 100 has an air inlet 110 and a filter 120 communicating with the air inlet 110. The drive assembly 200 is disposed on the main body 100. The cleaning assembly 300 includes a fixing frame 310 and a comb tooth 320 connected to the fixing frame 310. The comb tooth 320 abuts against the filter 120. The fixing frame 310 is connected to the drive assembly 200. The drive assembly 200 is used to drive the fixing frame 310 and the comb tooth 320 connected to the fixing frame 310 to move relative to the filter 120 to clean the filter 120.

[0103] The aforementioned air purification device 10 has at least the following beneficial effects: By setting up the drive component 200 and the cleaning component 300, automatic cleaning of the filter 120 is achieved, reducing maintenance costs and time, and making it more convenient to use. During the cleaning process, the contact movement between the comb teeth 320 and the filter 120 not only removes attached dust and particles, but also prevents the cleaning component 300 from clogging due to dirt entanglement. Driven by the drive component 200, the comb teeth 320 can effectively remove dust and particles from the filter 120, improving the unobstructed flow of the filter 120, increasing the overall purification efficiency of the air purification device 10, reducing the operating load of the device, extending the service life of the air purification device 10, and improving the reliability and durability of the device.

[0104] Please see Figure 16 In some embodiments, the cleaning assembly 300 further includes an elastic element 330. The fixing frame 310 includes a fixing frame 310 and a comb tooth 320. The fixing frame 310 is connected to the drive assembly 200. The elastic element 330 elastically abuts between the fixing frame 310 and the comb tooth 320, so that the comb tooth 320 can be held against the filter screen 120 under the elastic force of the elastic element 330. The elastic element 330 elastically abuts between the fixing frame 310 and the comb tooth 320, and can continuously apply appropriate pressure to hold the comb tooth 320 against the filter screen 120. This design improves the automatic adjustment of the pressure applied by the comb tooth 320 to the filter screen 120, which improves the cleaning effect and reduces excessive wear on the filter screen 120. The elastic element 330 can also buffer the wear or damage that may occur to the cleaning assembly 300 during operation, thus extending the service life of the equipment. In addition, this design allows the comb teeth 320 to adapt to filters 120 of different thicknesses or materials, improving the adaptability and versatility of the air purification device 10, thereby significantly enhancing the overall performance of the device and the user experience.

[0105] Specifically, such as Figure 16 and Figure 17As shown, in some embodiments, the cleaning component 300 further includes a snap-fit ​​portion 340, which is disposed on the side of the comb tooth 320 facing the fixing frame 310. The fixing frame 310 is provided with a limiting groove 3111 on the side facing the comb tooth 320. A snap-fit ​​hole 3112 is provided at the bottom of the limiting groove 3111. The snap-fit ​​portion 340 passes through the snap-fit ​​hole 3112 and can snap onto the periphery of the snap-fit ​​hole 3112. An elastic member 330 is sleeved on the snap-fit ​​portion 340 and elastically abuts against the bottom of the limiting groove 3111 and the comb tooth 320.

[0106] More specifically, such as Figure 17 As shown, in some embodiments, the outer peripheral surface of the snap-fit ​​portion 340 away from the comb tooth 320 is provided with a snap-fit ​​rib 341, which can snap onto the periphery of the snap hole 3112 on the side opposite to the comb tooth 320. The snap-fit ​​portion 340 is located on the side of the comb tooth 320 facing the fixing frame 310 and passes through the snap hole 3112 at the bottom of the limiting groove 3111 of the fixing frame 310, and fits tightly with the periphery of the snap hole 3112. This design improves the reliability of the connection between the two fixing frames 310, reduces the possibility of loosening or displacement of the components during operation, and thus improves the overall stability of the equipment. At the same time, the elastic member 330 is sleeved on the snap-fit ​​portion 340, and its two ends elastically abut against the bottom of the limiting groove 3111 and the comb tooth 320, respectively. This not only provides the necessary elasticity so that the cleaning component 300 can effectively apply appropriate pressure to the filter screen 120, but also reduces the wear of the component caused by vibration or impact through buffering. This enhances the durability of the equipment and extends its service life. Furthermore, the design simplifies installation and maintenance; the cleverly designed snap-fit ​​mechanism 340 makes component assembly and disassembly easier, facilitating subsequent maintenance and cleaning.

[0107] More specifically, such as Figure 17As shown, in some embodiments, the engaging portion 340 is columnar and its length is greater than the depth of the locking hole 3112. When the comb teeth 320 press against the elastic member 330 under the pressure of the filter screen 120, the engaging portion 340 can extend and retract within the locking hole 3112. The engaging portion 340 is designed to be columnar, and its length is greater than the depth of the locking hole 3112. This design allows the engaging portion 340 to extend and retract within the locking hole 3112. When the comb teeth 320 press against the filter screen 120, it pushes the comb teeth 320 to press against the elastic member 330. At this time, the engaging portion 340 can extend and retract within the locking hole 3112, thereby providing a certain buffer space. This flexibility allows the cleaning component 300 to better adapt to changes when subjected to external forces, reducing the impact of direct impacts and pressures on the component, thereby improving the structural integrity of the component. This design not only improves the durability of the component but also enhances its adaptability under different working conditions, improving the stability and effectiveness of the cleaning function. In this way, the equipment can cope with various external interferences more smoothly during operation, thus extending its service life.

[0108] Please see Figure 19 In some embodiments, the retaining frame 310 and the comb teeth 320 are integrally formed. This integral design improves the structural strength and stability of the assembly, eliminating potential loosening or misalignment issues that could arise from connections between multiple independent components. Secondly, this design simplifies the manufacturing process, reducing assembly steps and time, thereby lowering production costs. Furthermore, the integral structure reduces potential points of failure, enhancing the durability and reliability of the assembly. With no unnecessary connecting parts, the cleaning assembly 300 can transmit force and motion more efficiently during operation, improving its working efficiency.

[0109] Specifically, such as Figure 19 As shown, in some embodiments, the comb member 320 further includes comb teeth 360 and an elastic connecting plate 350. One end of the elastic connecting plate 350 is connected to the fixing frame 310, and the other end is connected to the comb teeth 360. The fixing frame 310 is integrally formed with the elastic connecting plate 350 and the comb teeth 360. The elastic connecting plate 350 can elastically deform under the support of the filter screen 120 so that the comb teeth 360 always abuts against the filter screen 120. One end of the elastic connecting plate 350 is connected to the fixing frame 310, and the other end is connected to the comb teeth 360. The elastic connecting plate 350 can elastically deform under the support of the filter screen 120. This means that when external forces act on the cleaning component 300, the elastic connecting plate 350 can absorb and buffer these forces, thereby protecting the comb teeth 360 and other components from damage. In addition, this elastic deformation improves the firmness of the close contact between the comb teeth 360 and the filter screen 120, improving the cleaning effect.

[0110] More specifically, such as Figure 19 As shown, in some embodiments, the resilient connecting plate 350 has a groove 351 extending along the width direction of the filter screen 120. The resilient connecting plate 350 can elastically deform at the groove 351 under the resistance of the filter screen 120. The design of the groove 351 enhances the elastic characteristics of the resilient connecting plate 350. By designing the groove 351 in a specific direction, i.e., the groove 351 can be approximately elongated and extend along the width direction of the filter screen 120, the resilient connecting plate 350 can deform more easily when subjected to force, thereby effectively absorbing and buffering external forces. This helps protect the comb teeth 360 and other related components, extending their service life. The design of the groove 351 allows the resilient connecting plate 350 to more flexibly adapt to the surface shape and irregularities of the filter screen 120. The groove 351 allows the resilient connecting plate 350 to flexibly adjust its shape to adapt to the surface of the filter screen 120 while maintaining sufficient contact force, thereby improving the comprehensiveness and consistency of the cleaning effect. Furthermore, the grooves 351 extending along the width direction effectively distribute and manage stress, allowing the resilient connecting plate 350 to bear pressure evenly during operation. This not only improves the durability of the component but also reduces the risk of damage caused by localized stress concentration. Finally, this design enhances the functionality and reliability of the cleaning component 300 without adding extra complexity, providing users with a more efficient and durable solution. It also reduces the amount of material used in the cleaning component 300, which helps reduce manufacturing costs and lighten its weight.

[0111] Please see Figure 20 In some embodiments, the comb teeth 320 have sharp edges that abut against the filter screen 120 and are used to scrape away dirt from the filter screen 120. The sharp edges of the comb teeth 320 effectively scrape away dirt, such as dust and hair, adhering to the filter screen 120, directly improving the cleanliness and permeability of the filter screen 120, enabling the device to operate continuously and efficiently. By reducing the accumulation of dirt, the dust removal blade 321 also reduces the risk of filter screen 120 clogging, thereby maintaining optimal device performance.

[0112] Specifically, in some embodiments, the comb teeth 320 extend along the width direction of the filter screen 120. By extending along the width direction, the comb teeth 320 can cover a larger surface area of ​​the filter screen 120, allowing for more comprehensive contact with dirt on the filter screen 120 during cleaning. This enables more efficient removal of dust, hair, and other adhering substances, improving the overall cleaning effect and permeability of the filter screen 120. Furthermore, the width-direction extension design helps achieve uniform cleaning force, reducing potential damage to the filter screen 120 caused by excessive localized pressure, thereby extending the service life of the filter screen 120.

[0113] More specifically, such as Figure 20 As shown, in some embodiments, the comb-like component 320 has multiple cleaning teeth 322 spaced apart along the width direction of the filter screen 120 on its edge abutting against the filter screen 120. The cleaning teeth 322 are used to scrape away dirt from the filter screen 120. The spacing between any two adjacent cleaning teeth 322 in the width direction of the filter screen 120 can be 5-6 mm, and the height of each cleaning tooth 322 can be 2-4 mm. The comb-like component 320 is designed with multiple cleaning teeth 322 spaced apart on its edge abutting against the filter screen 120. The main purpose of this design is to effectively scrape away dirt from the filter screen 120 while reducing the risk of the comb teeth themselves becoming entangled with hair. The spaced cleaning teeth 322 reduce the risk of long, thin dirt such as hair becoming entangled between the teeth during cleaning. This design not only improves cleaning efficiency but also reduces maintenance difficulty because the cleaning teeth 322 are less likely to be clogged or have their normal function affected by entanglement. This allows the equipment to maintain efficient filtration and cleaning even after long-term operation, reducing potential performance degradation or equipment failure caused by the cleaning teeth 322 becoming entangled. Overall, this design provides users with a more reliable and low-maintenance user experience.

[0114] Please see Figure 18 In some embodiments, the air purification device 10 further includes a collection box 400, which is located on the side of the filter 120 near the air inlet 110 and below the cleaning component 300. The comb teeth 320 can move up and down along the height direction of the filter 120 under the drive component 200 to sweep off the dirt on the filter 120 and collect it into the collection box 400. By setting the collection box 400 on the side of the filter 120 near the air inlet 110 and positioning it below the cleaning component 300, the system can efficiently collect the cleaned dirt. The comb teeth 320 moves up and down along the height direction of the filter 120 under the drive component 200, which allows the comb teeth 320 to cover the entire surface area of ​​the filter 120 relatively comprehensively. During the cleaning process, the comb teeth 320 effectively sweep off the dust, hair, and other dirt attached to the filter 120 through its up and down movement and directly guide it into the collection box 400 below. This design not only improves cleaning efficiency but also enables centralized collection of waste, preventing secondary pollution. Furthermore, the collection box 400 makes cleaning the collected waste more convenient for users; they simply need to empty it periodically.

[0115] Please see Figure 21 and Figure 22In some embodiments, the bottom edge of the filter 120 is provided with a plurality of anti-fouling teeth 121 spaced apart along its width direction. When the comb 320 moves under the drive assembly 200 to below the filter 120 and then rises again, the anti-fouling teeth 121 can abut against the comb 320 to scrape off residual dirt on the comb 320 and collect it into the collection box 400. The bottom edge of the filter 120 is designed with a plurality of anti-fouling teeth 121, which are spaced apart along the width direction of the filter 120. This design further improves cleaning efficiency, especially for dirt that may remain on the comb 320. When the comb 320 moves under the drive assembly 200 to below the filter 120 and is about to rise again, the anti-fouling teeth 121 will contact the comb 320, and the anti-fouling teeth 121 can effectively scrape off residual dust, hair and other dirt on the comb 320. The scraped-off dirt falls off and is collected in the collection box 400 below. This design not only improves the cleanliness of the filter 120 but also ensures that the comb teeth 320 are relatively clean after each cleaning cycle, thereby improving the overall efficiency and performance of the cleaning assembly 300. Furthermore, this automated cleaning method reduces the need for manual intervention, lowers maintenance complexity, and provides users with a more convenient experience.

[0116] Specifically, in some embodiments, the gap between any two adjacent cleaning teeth 322 corresponds to at least one anti-fouling tooth 121. This design allows the anti-fouling tooth 121 to comprehensively cover and act on the entire surface of the comb during cleaning, particularly scraping away any dirt that may remain in the gap between any two adjacent cleaning teeth 322, thereby maximizing the removal of residual dirt. This structural arrangement not only improves cleaning efficiency but also reduces the possibility of dirt residue.

[0117] Please see Figure 18In some embodiments, the mounting bracket 310 has pressure ribs 313 on the side facing the collection box 400. When dirt on the filter screen 120 is collected into the collection box 400, the pressure ribs 313 can compress the dirt inside the collection box 400. In these embodiments, the mounting bracket 310 is designed to be more intelligent, with pressure ribs 313 on the side facing the collection box 400. When dirt on the filter screen 120 is swept off and collected into the collection box 400, the pressure ribs 313 can compress the dirt inside the collection box 400. This compression helps to compress the dirt, thereby increasing the capacity utilization of the collection box 400. This means that more dirt can be accommodated without increasing the volume of the collection box 400, extending the emptying cycle of the collection box 400 and reducing the frequency of maintenance for users. In addition, the design of the pressure ribs 313 helps to prevent loose accumulation of dirt inside the collection box 400, reducing the scattering of dirt when emptying the collection box 400. This design not only improves the efficiency of the air purifier 10, but also enhances the user experience, making the maintenance of the device simpler and cleaner.

[0118] Please see Figure 23 In some embodiments, the filter 120 includes a frame 122 and a filter portion 123 embedded within the frame 122. In these embodiments, the filter 120 is designed with two main parts: the frame 122 and the filter portion 123 embedded within the frame 122. The frame 122 provides structural support and stability, allowing the filter portion 123 to maintain its shape and position. This is crucial to prevent the filter 120 from deforming or shifting during use, thereby improving the stability and consistency of the filtration effect. Furthermore, this combined structure allows for the selection of different materials and technologies during design and manufacturing to optimize filtration performance. For example, the frame 122 can be made of a robust and durable material, while the filter portion 123 can be made of a material with specific filtration properties to meet different filtration needs. This flexibility allows the filter 120 to adapt to various application scenarios and usage conditions.

[0119] Specifically, in some embodiments, the frame 122 and the filter section 123 are integrally injection molded. This integral injection molding process simplifies the production process, reduces production costs, improves manufacturing efficiency, and shortens the production cycle. Furthermore, the integral injection molding eliminates seams or connection points between the frame 122 and the filter section 123, thereby enhancing the overall structural strength and stability. This reduces the risk of damage due to stress or pressure during use.

[0120] Specifically, in some embodiments, the filter section 123 is a PET mesh or a stainless steel mesh.

[0121] Specifically, in some embodiments, the thickness of the filter portion 123 is 0.15-0.2 mm.

[0122] Specifically, in some embodiments, the mesh density of the filter section 123 is 40-60 meshes per square inch. This range of mesh densities provides a balance, allowing the filter to effectively filter particles of a specific size while improving flowability. Here are some characteristics and applications of this mesh density: a 40-60 mesh density is suitable for filtering medium-sized particles. This density can capture larger particles while allowing smaller particles to pass through, thus achieving a balance between filtration efficiency and flowability.
