[0099] 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.

[0100] Please refer to Figures 1 to 3 The air handling device 100 provided in this application embodiment includes a base 10, a housing, a head (not shown in the figure), and a filter assembly 30.

[0101] The housing surrounds the filter assembly 30, and the housing and filter assembly 30 are connected between the base 10 and the head unit. The specific structure of the head unit is not specifically limited in this embodiment, as long as it can output airflow. For example, the head unit includes a fan and an exhaust hood, the exhaust hood being connected to the top of the housing. The fan includes fan blades and a blower, the fan blades being connected to the blower. The fan blades rotate under the action of the blower, creating an airflow channel within the housing. Figure 2 The arrows shown indicate the direction of airflow. This airflow channel allows air to enter through the housing, flow through the filter assembly, and then exit through the exhaust hood, thus filtering pollutants from the air and improving air quality.

[0102] According to relevant technologies, after a period of use, dust, hair, and other pollutants easily accumulate on the surface of the filter components of air purifiers. If not cleaned for a long time, this not only reduces the air purification effect but also increases the stress on the fan, affecting its lifespan. Currently, manually cleaning the filter components is time-consuming and labor-intensive, significantly reducing the user experience.

[0103] Based on this, embodiments of this application provide a filter cleaning device 40, which can achieve automatic cleaning, saving time and effort and improving the user experience. Embodiments of this application also provide an air handling device 100 with a filter cleaning device 40. This air handling device 100 uses at least a first rotating component 42 to drive the primary filter assembly 50 to rotate, and uses a cleaning mechanism 41 disposed around the primary filter assembly 50 to remove pollutants accumulated on its surface, achieving automatic cleaning, saving time and effort and improving the user experience.

[0104] The primary filter assembly is the first line of defense in a filter-type air purifier, mainly used to intercept large particulate pollutants in the air; it can also be other types of filters on the outermost layer.

[0105] The structure of the filter cleaning device 40 will be described in detail below using an air handling unit with a filter cleaning device 40 as an example.

[0106] For details, please refer to Figures 3 to 6 The filter cleaning device 40 provided in this embodiment includes a cleaning mechanism 41 and a first rotating component 42. The filter assembly 30 includes a primary filter assembly 50, which is connected to the first rotating component 42 and rotates vertically under the action of the first rotating component 42. The cleaning mechanism 41 is connected to the base 10 and located around the primary filter assembly 50. When the primary filter assembly 50 rotates, the cleaning mechanism 41 acts on the surface of the primary filter assembly 50 to remove contaminants from the surface of the primary filter assembly 50.

[0107] The number of filter cleaning devices 40 is not specifically limited in this embodiment of the application, and can be set according to factors such as the size of the air handling device 100, for example: one, two, three, four, or five.

[0108] In an alternative embodiment, when the number of filter cleaning devices 40 is at least two, each filter cleaning device 40 is circumferentially distributed around the rotation axis of the first rotating assembly 42.

[0109] In one alternative embodiment, at least two filter cleaning devices 40 are circumferentially distributed around the rotation axis of the first rotating assembly 42. Figure 4 The diagram shows an air handling unit 100 equipped with two filter cleaning devices 40, which are located around and evenly distributed around a primary filter assembly 50 with a circular cross-section.

[0110] In one alternative embodiment, please refer to Figure 3 , Figure 7 , Figure 8 and Figure 9 The cleaning mechanism 41 includes a scraper 411, which is rotatably connected to the base 10 and moves along a first direction (i.e., Figure 2 As shown by the arrow s1, when the primary filter assembly 50 rotates, the scraper 411 abuts against the surface of the primary filter assembly 50, and the first direction is the direction of the rotation axis 4111 of the first rotating assembly 42.

[0111] The scraper 411, which comes into contact with the surface of the pre-filter assembly 50, scrapes up the pollutants accumulated on the surface of the pre-filter assembly 50, allowing the pollutants to detach from the pre-filter assembly 50. Removing the pollutants from the surface of the pre-filter assembly 50 significantly reduces the impact of pollutant blockage on the air purification effect.

[0112] In addition, the rotation of the pre-filter assembly 50 can reduce the concentration of pollutants during filtration. This can be understood as follows: pollutants always enter from a certain position of the housing. For example, pets always like to rub against a certain position of the housing. The hair generated during the rubbing process always concentrates at a certain position of the pre-filter assembly 50, putting great pressure on the pre-filter assembly 50. The rotation of the pre-filter assembly 50 can disperse the pollutants that concentrate from a certain position, thereby improving the purification effect.

[0113] In an alternative embodiment, the scraper member 411 and the primary filter assembly 50 are in a first direction (i.e., Figure 2 The lengths in the direction of arrow s1 shown in the diagram match. This can be understood as the scraper member 411 having the same length as the primary filter assembly 50 in the first direction, thereby ensuring that the scraper member 411 can contact the entire surface of the primary filter assembly 50 and guarantee the scraping effect.

[0114] In an optional embodiment, the length of the scraper member 411 in the first direction may be greater than or less than that of the pre-filter assembly 50. When the length of the scraper member 411 is greater than the length of the pre-filter assembly 50, the cleaning force at the bottom and top of the pre-filter assembly 50 can be guaranteed. When the length of the scraper member 411 is less than the length of the pre-filter assembly 50, space can be reduced, energy can be saved, and cleaning efficiency can be guaranteed.

[0115] In one alternative embodiment, please refer to Figure 3 , Figure 4 and Figure 5 The cleaning mechanism 41 also includes a dust collection box 412, which is connected to the base 10 and extends along a first direction. The dust collection box 412 has an inlet 4124, through which the scraper 411 scrapes pollutants from the surface of the primary filter assembly 50 and enters the storage space 4121 of the dust collection box 412 through the inlet 4124.

[0116] The dust collection box 412 collects the pollutants scraped off from the primary filter assembly 50 by the scraper 411, which greatly reduces the re-adhesion of the scraped pollutants onto the surface of the primary filter assembly 50 and improves the air purification effect.

[0117] In an optional embodiment, the cleaning mechanism 41 further includes an elastic element 413 connected between the scraper 411 and the dust collection box 412, so that the scraper 411 adaptively abuts against the surface of the primary filter assembly 50. The elastic element 413 can be a compression spring or a torsion spring, and this embodiment does not impose a specific limitation.

[0118] The elastic element 413 ensures that the scraper element 411 always abuts against the surface of the primary filter assembly 50, guaranteeing the scraping effect of the scraper element 411 on the primary filter assembly 50. This avoids uneven force during the scraping process of the scraper element 411 on the surface of the primary filter assembly 50 due to deformation of the primary filter assembly 50 after long-term use or the accumulation of a lot of contaminants on a certain part of its surface. When the scraper element 411 is subjected to uneven force, it will rotate and detach from the surface of the primary filter assembly 50.

[0119] In an optional embodiment, the scraper 411 can be rotatably connected to the dust collection box 412 via the pivot 4111, and with the help of the elastic member 413, it is kept in contact with the surface of the primary filter assembly 50 at all times, so as to prevent the scraper 411 from detaching from the surface of the primary filter assembly 50 and further ensure the cleaning effect.

[0120] In an optional embodiment, the dust collection box 412 is provided with a groove (not shown in the figure), and the scraper 411 matches the groove and can move in the groove. Through the design of the groove, the scraper 411 can also be provided with a certain degree of freedom, thereby ensuring that the scraper 411 can always abut against the surface of the primary filter assembly 50 under the action of the elastic member 413.

[0121] The cleaning mechanism 41 also includes a roller brush assembly 414. The roller brush assembly 414 is configured to send the contaminants scraped off the surface of the primary filter assembly 50 by the scraper 411 into the storage space 4121 of the dust collection box 412, thereby achieving self-cleaning and self-collection of contaminants and solving the possibility of secondary pollution caused by the contaminants scraped off by the scraper 411.

[0122] The following is a detailed introduction to the roller brush assembly 414.

[0123] For details, please refer to Figure 3 , Figure 7 , Figure 8 and Figure 9 The roller brush assembly 414 includes a roller brush 4141, a roller 4142, and a roller brush drive 4143. The roller brush 4141 is fitted onto the roller 4142, and the roller 4142 is connected to the roller brush drive 4143. The roller 4142 is rotatably connected to the base 10. Under the driving force of the roller brush drive 4143, the roller brush 4141 rotates around its own axis following the roller 4142. The roller brush drive 4143 is a rotary motor, but it is not limited to this.

[0124] The roller brush 4141 and the scraper 411 are arranged adjacent to each other with a gap between them. During the rotation process, the roller brush 4141 carries the pollutants scraped off from the primary filter assembly 50 by the scraper 411 into the storage space 4121 of the dust collection box 412.

[0125] Please refer to Figure 4 and Figure 5 In an alternative embodiment, the primary filter assembly 50 can be rotated clockwise (i.e., Figure 5 The rollers rotate (in the direction of arrow r1 shown in the image) and the rollers 4142 rotate counterclockwise (that is, ...). Figure 5 The direction of the arrow r2 shown in the image is rotated.

[0126] The counterclockwise rotating roller 4142 carries the contaminants that have detached from the surface of the primary filter assembly 50 into the dust collection box 412. The contaminants enter the dust collection box 412 through the gap between the roller brush 4141 and the scraper 411.

[0127] It should be noted that the primary filter assembly 50 is not limited to clockwise rotation, but can also rotate counterclockwise. The selection can be based on the specific structure of the scraper 411, so as to scrape up and collect the contaminants on the surface of the primary filter assembly 50.

[0128] In an alternative embodiment, in the first direction (i.e., Figure 2 As shown by arrow s1 in the diagram, the length of the roller brush 4141 is equal to the length of the scraper 411. This ensures that all contaminants scraped off by the scraper 411 in the first direction can be affected by the roller brush 4141.

[0129] In an optional embodiment, in the first direction, the length of the roller brush 4141 is greater than or less than the length of the scraper 411. When the length of the roller brush 4141 is greater than the length of the scraper 411, the roller brush 4141 can achieve the cleaning force of the top and bottom ends of the scraper 411. Since contaminants tend to accumulate in the middle of the primary filter assembly 50, setting the length of the roller brush 4141 to be less than the length of the scraper 411 reduces space occupation, saves energy, and ensures cleaning efficiency.

[0130] The cleaning mechanism 41 also includes a roller brush scraper 415, which scrapes away contaminants remaining on the surface of the roller brush 4141 and places the scraped contaminants in the storage space 4121 of the dust collection box 412, thereby greatly reducing the residue of contaminants on the surface of the roller brush 4141 and also reducing the possibility of secondary pollution.

[0131] The following is a detailed introduction to the roller brush scraper 415.

[0132] Specifically, the roller brush scraper 415 contacts the roller brush 4141 and is used to scrape off contaminants remaining on the surface of the roller brush 4141 during rotation.

[0133] In an optional embodiment, the roller brush scraper 415, the scraper 411, and the roller brush 4141 are all located at the inlet 4124 of the dust collection box 412. The roller brush 4141 is located between the roller brush scraper 415 and the scraper 411. The contaminants scraped by the scraper 411 enter the storage space 4121 of the dust collection box 412 under the rotation of the roller brush 4141, and are removed from the roller brush 4141 by the blocking effect of the roller brush scraper 415.

[0134] The scraper 411 scrapes away contaminants from the surface of the rotating primary filter assembly 50. The scraped contaminants enter the storage space 4121 of the dust collection box 412 under the action of the roller brush 4141. Some contaminants remain on the surface of the roller brush 4141. The contaminants remaining on the surface of the roller brush 4141 are removed from the surface of the primary filter assembly 50 by the obstruction of the roller brush scraper 415 and are collected in the storage space 4121 of the dust collection box 412.

[0135] The roller brush scraper 415, scraper 411, and roller brush 4141 are all located at the inlet 4124 of the dust collection box 412. This not only allows the pollutants scraped off by the scraper 411 to be carried into the storage space 4121 of the dust collection box 412, but also prevents the pollutants in the storage space 4121 of the dust collection box 412 from leaving. This greatly reduces the possibility of secondary pollution caused by pollutants scraped off from the surface of the primary filter assembly 50, improves the cleaning effect on the primary filter assembly 50, and further improves the air purification effect of the air handling device 100.

[0136] In one alternative embodiment, please refer to Figure 6 and Figure 8 The dust collection box 412 is provided with a cover 4122 and a box body 4123. The cover 4122 is detachably connected to the box body 4123. The box body 4123, the cover 4122 and the base 10 constitute the storage space 4121 of the dust collection box 412. The cover 4122 is connected to the outer edge of the base 10.

[0137] The inlet 4124 of the dust collection box 412 is located on the box body 4123. The connection method between the cover 4122 and the box body 4123 is not specifically limited in this embodiment; for example, a snap-fit ​​connection can be used to facilitate the removal and installation of the cover 4122 from the box body 4123. The cover 4122 is connected to the outer edge of the base 10, allowing the user to easily remove the cover 4122 and also facilitating the removal of contaminants stored in the storage space 4121 within the dust collection box 412.

[0138] In an optional embodiment, the scraper member 411 abutting against the end of the primary filter assembly 50 is made of one of silicone, hard rubber, or a brush.

[0139] In one alternative embodiment, please refer to Figure 3 and Figure 5 The angle between the tangent of the circle where the primary filter assembly 50 contacts the scraper 411 and the scraper 411 (i.e., Figure 5 The angle a) shown is less than or equal to 90 degrees. This angle range can improve the scraping effect of the scraper 411 on the surface of the primary filter assembly 50 for removing contaminants.

[0140] In an optional embodiment, the angle between the tangent of the circle containing the contact point between the primary filter assembly 50 and the scraper member 411 and the scraper member 411 (i.e., Figure 5 The angle a) shown is less than or equal to 60 degrees. This angle range can further improve the scraping effect of the scraper 411 on the surface of the primary filter assembly 50 for removing contaminants.

[0141] In an alternative embodiment, the roller brush 4141 is a brush cloth or silicone. The brush cloth or silicone more easily carries contaminants into the dust collection box 412, improving cleaning effectiveness.

[0142] In an optional embodiment, the distance between the roller brush 4141 and the pre-filter assembly 50 is less than or equal to 9 mm. The closer the roller brush 4141 is to the pre-filter assembly 50, the less contaminants accumulate between the scraper 411 and the roller brush 4141, thus avoiding contaminant buildup and improving cleaning efficiency and cleaning effect.

[0143] In an optional embodiment, the distance between the roller brush 4141 and the pre-filter assembly 50 is less than or equal to 6 mm. This range of distances between the roller brush 4141 and the pre-filter assembly 50 can further improve the cleaning effect.

[0144] In an optional embodiment, the end of the roller brush scraper 415 that contacts the roller brush 4141 is fitted with a brush cloth.

[0145] In an optional embodiment, the end of the roller brush scraper 415 that contacts the roller brush 4141 has a comb-tooth structure, which can improve the scraping effect of the roller brush scraper 415 on the roller brush 4141.

[0146] In one alternative embodiment, please refer to Figure 3The first rotating assembly 42 includes a first rotating drive 421 and a first rotating disk 422. The first rotating disk 422 is connected to the first rotating drive 421, and the first rotating disk 422 drives the primary filter assembly 50 to rotate together under the driving action of the first rotating drive 421. The first rotating drive 421 can be a rotary motor, but it is not limited to this.

[0147] The output shaft of the rotary motor drives the gear to rotate. The first rotating disk 422 is provided with 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 the first rotary drive component 421 can be set according to the requirements, and can be one, two, or three.

[0148] The roller brush drive 4143 can share a motor with the first rotary drive 421 and be connected by gears, or it can use two separate motors.

[0149] In an optional embodiment, the pre-filter assembly 50 includes a first support 510 and a pre-filter (not shown), the pre-filter being connected to the side of the first support 510 near the cleaning mechanism 41. The pre-filter is used to filter out large particulate pollutants, such as pet and human hair, dust, pollen, willow catkins, and flying insects.

[0150] The first bracket 510 is connected to the first rotating disk 422. When the first rotating disk 422 rotates, it can drive the first bracket 510 to rotate together.

[0151] However, the primary filter assembly 50 and other filter assemblies need to be replaced after a long period of use. When replacing them, the primary filter assembly 50 needs to be disassembled. The primary filter assembly 50 needs to rotate with the first rotating disk 422. How to make the primary filter assembly 50 rotate with the first rotating disk 422 while also making it easy to disassemble the primary filter assembly 50 is a problem that needs to be solved.

[0152] Based on this, the first limiting member 4221 and the second limiting member 511 in the embodiments of this application can enable the primary filter assembly 50 to rotate together with the first rotating disk 422, and can easily disassemble the primary filter assembly 50.

[0153] For details, please refer to Figure 10a , Figure 10b and Figure 11 The first rotating disk 422 is provided with a first limiting member 4221, which extends in its radial direction. The first bracket 510 is provided with a second limiting member 511 that matches the first limiting member 4221. Under the action of the first limiting member 4221 and the second limiting member 511, the primary filter assembly 50 rotates together with the first rotating disk 422.

[0154] In an optional embodiment, the first limiting member 4221 is a first protruding rib 4222 provided on the first rotating disk 422, and the second limiting member 511 is a first slot 5111 provided on the first bracket 510. The first protruding rib 4222 and the first slot 5111 both extend radially along the first rotating disk 422, and the first protruding rib 4222 matches the first slot 5111.

[0155] Please refer to Figure 11 Since the first limiting member 4221 extends radially along the first rotating disk 422, when the first bracket 510 needs to be disassembled, the first bracket 510 can be moved out radially, making disassembly and assembly convenient and quick.

[0156] It should be noted that, please refer to Figure 6 The first bracket 510 is composed of two semi-circular brackets joined together. The two semi-circular brackets can be connected by magnetic attraction, but this is not the only method. The magnetic connection between the two semi-circular brackets allows one of the semi-circular brackets to be easily removed from the air handling unit 100.

[0157] In an optional embodiment, the air handling device 100 further includes a high-efficiency filter assembly 60, with a pre-filter assembly 50 surrounding the high-efficiency filter assembly 60. The high-efficiency filter assembly 60 includes a high-efficiency filter and a second support 610, with the high-efficiency filter connected to the second support 610 on the side closer to the pre-filter assembly 50.

[0158] High-efficiency particulate filters are used to filter small particulate pollutants, such as smoke, bacteria, viruses, dust mite excrement, pet dander, asbestos fibers, odors, formaldehyde, etc., such as HEPA or activated carbon. There is no limitation on the type of high-efficiency filter here, and you can choose according to actual needs.

[0159] This can be understood as first using a pre-filter to remove larger particulate pollutants, and then using a high-efficiency filter to remove smaller particulate pollutants, thereby improving the filtration effect of the air handling unit 100. Of course, the air handling unit 100 can also be equipped with a third or fourth filter to improve the filtration effect; however, this application embodiment does not limit the number or type of filters.

[0160] In one alternative embodiment, please refer to Figure 6 The second bracket 610 is connected to the base 10, which can be understood as the second bracket 610 not rotating with the first rotating component 42.

[0161] In an optional embodiment, the air handling unit 100 further includes a support column 70 connected to the base 10 and used to support the head of the air handling unit 100. The support column 70 can improve the structural stability of the device, thereby ensuring the air purification effect.

[0162] There are two support columns 70, which are symmetrically arranged. The second bracket 610 includes two arc-shaped brackets that are connected to the support columns 70, thus sealing the HEPA filter with the support columns 70 to ensure the filtration effect of the HEPA filter. Of course, the number of support columns 70 is not limited to two; it can also be three or four. The corresponding number of arc-shaped brackets is also not limited to two.

[0163] It should be noted that when there are many arc-shaped supports and it is inconvenient to move them radially, the high-efficiency filter can be moved out from the machine head along the first direction to replace it.

[0164] In one alternative embodiment, please refer to Figure 12 The filter cleaning device 40 also includes a second rotating component, which is mounted on the base 10 and connected to the primary filter assembly 50. The second bracket 610 is connected to the second rotating component, and the primary filter assembly 50 and the high-efficiency filter assembly 60 rotate together under the action of the second rotating component.

[0165] The high-efficiency filter assembly 60 rotates together with the pre-filter assembly 50. On the one hand, the gap between the high-efficiency filter assembly 60 and the pre-filter assembly 50 can be very small or even non-existent, thereby improving the support strength of the pre-filter assembly 50 and the high-efficiency filter assembly 60. On the other hand, the rotation of the pre-filter assembly 50 and the high-efficiency filter assembly 60 together can improve the resistance to the scraper 411, thereby improving the cleaning effect and greatly reducing the possibility of deformation of the pre-filter assembly 50.

[0166] In an optional embodiment, the high-efficiency filter assembly 60 is connected to the pre-filter assembly 50. For example, the high-efficiency filter assembly 60 and the pre-filter assembly 50 are connected together by snap-fit, which can further improve the support strength and stability of the pre-filter assembly 50, and also facilitate disassembly and installation as a single unit.

[0167] Figure 12 The diagram shows a second bracket 610 embedded in a first bracket 510, which greatly increases the support for the primary filter assembly 50 and the high-efficiency filter assembly 60, thereby ensuring the structural stability of the air handling unit 100.

[0168] It should be noted that the high-efficiency filter and the pre-filter are not shown in the figure. The position between the second bracket 610 and the first bracket 510 is used to install the high-efficiency filter.

[0169] In an optional embodiment, the second rotating component includes a second rotating drive (not shown in the figure) and a second rotating disk 431. The second rotating drive is connected to the base, and the second rotating disk 431 is rotatably connected to the base 10. The second rotating disk 431 is connected to the second rotating drive, and the second rotating disk 431 drives the primary filter assembly 50 and the high-efficiency filter assembly 60 to rotate together under the driving action of the second rotating drive.

[0170] In one optional embodiment, the first support 510, the pre-filter, the second support 610, and the high-efficiency filter are all integrally formed structures.

[0171] The one-piece molding structure can greatly increase its structural strength. The structural strength of the first support 510, the pre-filter, the second support 610 and the high-efficiency filter are all enhanced. The structural strength of the four connected together will be more stable, thus providing greater resistance to the scraper 411 during the cleaning process, so that the scraper 411 can stick tightly to the pre-filter and achieve a better cleaning effect.

[0172] Additionally, when it is necessary to disassemble the pre-filter assembly 50 or the high-efficiency filter assembly 60, the pre-filter assembly 50 and the high-efficiency filter assembly 60 can be disassembled as a whole to improve the ease of disassembly. For example, they can be disassembled as a whole from the head or from the side of the housing.

[0173] It should be noted that when the primary filter assembly 50 and the high-efficiency filter assembly 60 rotate together, there is a difference between the first rotating assembly 42 and the second rotating assembly. The difference is that the second rotating disk 431 has a larger area and can support both the first support 510 and the second support 610 at the same time.

[0174] Furthermore, when the first support 510, the pre-filter, the second support 610, and the high-efficiency filter are all integrally molded structures, the connection method between the second rotating disk 431 and the first support 510 or the second support 610 is different, so as to facilitate the disassembly and assembly of the pre-filter assembly 50 and the high-efficiency filter assembly 60. However, when the first support 510, the pre-filter, the second support 610, and the high-efficiency filter are all spliced ​​structures, the connection method between the second rotating disk 431 and the first support 510 or the second support 610 can be the same as the connection method between the first rotating disk 422 and the first support 510. This application does not impose any restrictions, and the choice can be made according to specific needs.

[0175] In an optional embodiment, when the first bracket 510, the pre-filter, the second bracket 610, and the high-efficiency filter are all integrally formed structures, and it is necessary to disassemble the pre-filter assembly 50 and the high-efficiency filter assembly 60 as a whole from the side of the housing, the second rotating disk 431 is connected to the first bracket 510 by magnetic attraction. While ensuring that the pre-filter assembly 50 and the high-efficiency filter assembly 60 rotate with the second rotating disk 431, they can also be disassembled from the side of the housing.

[0176] Of course, the connection between the second rotating disk 431 and the first bracket 510 is not limited to magnetic attraction; they can also be connected by mechanical snap-fit. This application embodiment does not make specific limitations.

[0177] This application also provides an air purification device, including the air handling apparatus provided in any of the above embodiments.

[0178] 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.
