Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, and specifically to a filter component for an air purifier. Background Technology

[0002] Air purifiers, also known as air cleaners, air fresheners, or air purifiers, are products that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to effectively improve air cleanliness. They are mainly divided into household, commercial, industrial, and building types.

[0003] Existing air purifiers typically consist of filters including dust filters, activated carbon odor filters, and sterilization devices. Activated carbon has a shelf life of six months, and needs to be replaced every three months in heavily polluted environments. However, existing filter components are usually connected by bolts and threads, which are prone to rusting over time, making it difficult to disassemble and separate the filter components for cleaning, replacing activated carbon, and repairing the sterilization device. Therefore, it is necessary to solve the problem of the inconvenience of disassembling and separating existing air purifier filter components for cleaning, replacing activated carbon, and repairing the sterilization device. Utility Model Content

[0004] In view of the problems existing in the current filter assembly for air purifiers, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a filter component for air purifiers, which solves the problem that existing air purifier filter components are inconvenient to disassemble and separate for cleaning the filter, replacing the activated carbon, and repairing the sterilization and purification device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A filter assembly for an air purifier includes a base, a U-shaped hollow plate fixedly connected to the top of the base, honeycomb silicone breathable plates fixedly connected to the outer and inner walls of both ends of the U-shaped hollow plate through openings, activated carbon filling layers in the cavities at both ends of the U-shaped hollow plate, a snap-fit ​​seat fixedly connected to the top of the base, a mounting shell snapped into the cavity of the snap-fit ​​seat, a limiting mechanism for insertion into the mounting shell on the side wall of the snap-fit ​​seat, mounting openings at both ends of the top of the mounting shell for inserting filter screens, L-shaped snap-fit ​​plates fixedly connected to the bottom and top of the side walls of the mounting shell, a pre-filter screen plate snapped between the side walls of the two L-shaped snap-fit ​​plates, and a high-voltage electrostatic sterilization device snapped into the cavity of the mounting shell through an elastic support mechanism.

[0008] Preferably, the limiting mechanism includes a limiting rod, a first spring, and a socket. The limiting rod is slidably connected to both ends of the side wall of the snap-fit ​​seat through an opening. The first spring is sleeved on the rod wall of both ends of the limiting rod. The socket is provided at both ends of the side wall of the mounting shell. The other end of the first spring at both ends is inserted into the corresponding socket.

[0009] Preferably, the elastic support mechanism includes a second spring, a connecting plate, a snap-fit ​​slide rail, and a pressure plate. Multiple second springs are fixedly connected to the top of the cavity of the mounting shell, a connecting plate is fixedly connected to the bottom of the second spring, a snap-fit ​​slide rail is fixedly connected to the bottom of the connecting plate, the bottom of the snap-fit ​​slide rail is slidably connected to one end of the high-voltage electrostatic sterilization device, and pressure plates are fixedly connected to the side walls of both ends of the snap-fit ​​slide rail. The bottom of the pressure plates at both ends snaps into the openings at the top of both ends of the U-shaped hollow plate.

[0010] Preferably, the high-voltage electrostatic sterilization device includes a high-voltage generator and an electrode plate, with the electrode plate fixedly connected to the output end of the high-voltage generator.

[0011] Furthermore, a connecting ring is rotatably connected to one end of the filter screen.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a filter component for an air purifier.

[0026] This utility model provides, for example Figures 1-4The air purifier filter assembly shown includes a base 1, a U-shaped hollow plate 2 fixedly connected to the top of the base 1, honeycomb silicone breathable plates 3 fixedly connected to both outer and inner side walls of the U-shaped hollow plate 2 through openings, activated carbon filling layers 4 provided in the cavities of both ends of the U-shaped hollow plate 2, a snap-fit ​​seat 5 fixedly connected to the top of the base 1, a mounting shell 6 snapped into the cavity of the snap-fit ​​seat 5, a limiting mechanism for insertion into the mounting shell 6 provided on the side wall of the snap-fit ​​seat 5, mounting openings 7 at both ends of the top of the mounting shell 6, through which filter screen plates 8 are inserted, L-shaped snap-fit ​​plates 9 fixedly connected to the bottom and top of the side walls of the mounting shell 6, a pre-filter plate 10 snapped between the side walls of the two L-shaped snap-fit ​​plates 9, and a high-voltage electrostatic sterilization device 11 snapped into the cavity of the mounting shell 6 through an elastic support mechanism. The pre-filter plate 10, located between the side walls of the two L-shaped snap-fit ​​plates 9, effectively filters large particulate impurities and hair in the air. The system is designed to be easily disassembled and cleaned. A filter screen 8, located in the mounting port 7, further filters impurities from the air and is easy to disassemble and clean. Honeycomb silicone breathable plates 3, located on the inner and outer walls of the U-shaped hollow plate 2, and activated carbon filling layer 4 within the cavity, purify odors from the air and facilitate replacement of the activated carbon filling layer 4. A high-voltage electrostatic sterilization device 11 effectively removes particulate matter and microorganisms from the air through high-voltage electrostatic adsorption air disinfection technology, while remaining harmless to humans. A mounting shell 6, fixed in the locking seat 5 by a limiting mechanism, allows for easy disassembly of the mounting shell 6 to clean and replace internal components. This solves the problem of existing air purifiers where filter components are difficult to disassemble for cleaning, activated carbon replacement, and maintenance of the sterilization and purification device.

[0027] In order to limit the position of the mounting shell 6 in the card slot 5, such as Figure 1 and 2 As shown, the limiting mechanism includes a limiting rod 12, a first spring 13, and a socket 14. The limiting rod 12 is slidably connected to both ends of the side wall of the snap-fit ​​base 5 through openings. The first spring 13 is sleeved on the rod wall of the limiting rod 12 at both ends. The socket 14 is opened at both ends of the side wall of the mounting shell 6. The other end of the first spring 13 at both ends is inserted into the corresponding socket 14. By using the limiting rod 12 set at both ends of the side wall of the snap-fit ​​base 5, the mounting shell 6 is limited in the snap-fit ​​base 5 by inserting one end into the socket 14 opened in the mounting shell 6.

[0028] In order to ensure that the end pressure plates 18 and the U-shaped hollow plate 2 are pressed together, preventing the component from tipping over or tilting and causing the activated carbon filling layer 4 to flow out, such as Figure 1 and 4As shown, the elastic support mechanism includes a second spring 15, a connecting plate 16, a snap-fit ​​slide rail 17, and a pressure plate 18. Multiple second springs 15 are fixedly connected to the top of the cavity of the mounting shell 6. The bottom of the second spring 15 is fixedly connected to the connecting plate 16. The bottom of the connecting plate 16 is fixedly connected to the snap-fit ​​slide rail 17. The bottom of the snap-fit ​​slide rail 17 is slidably connected to one end of the high-voltage electrostatic sterilization device 11. Pressure plates 18 are fixedly connected to both side walls of the snap-fit ​​slide rail 17. The bottom of the two pressure plates 18 is snapped into the openings at the top of both ends of the U-shaped hollow plate 2. The snap-fit ​​slide rail 17 is used to install the high-voltage electrostatic sterilization device 11 and facilitate disassembly and maintenance. The pressure plates 18 at both ends of the snap-fit ​​slide rail 17 are pressed by the second springs 15 to press the two pressure plates 18 against the openings at both ends of the U-shaped hollow plate 2, preventing the components from tipping over or tilting and causing the activated carbon filling layer 4 to flow out.

[0029] In order for the high-voltage electrostatic sterilization device 11 to achieve the adsorption sterilization function, such as Figure 1 and 4 As shown, the high-voltage electrostatic sterilization device 11 includes a high-voltage generator 19 and an electrode plate 20. The output end of the high-voltage generator 19 is fixedly connected to the electrode plate 20. By utilizing the high-voltage electrostatic sterilization device 11 composed of the high-voltage generator 19 and the electrode plate 20, the high-voltage electrostatic sterilization device 11 can achieve the adsorption sterilization function.

[0030] To facilitate the removal of the filter screens 8 at both ends, such as Figure 1 As shown, a connecting ring 21 is rotatably connected to one end of the filter screen plate 8. The connecting ring 21 facilitates the removal of the filter screen plates 8 from the mounting port 7 at both ends.

[0031] Finally, to facilitate the movement of the filter components, such as... Figure 1 and 2 As shown, a rotating handle 22 is fixedly connected to the top of the mounting housing 6, which facilitates the movement of the filter assembly.

[0032] How to use:

[0033] When components are damaged and require repair, replacement, or cleaning, the mounting shell 6 and the snap-fit ​​seat 5 are separated by pulling out the limit rod 12. The activated carbon layer 4 in the U-shaped hollow plate 2 at the top of the base 1 is replaced. The pre-filter plate 10 is removed between the side walls of the L-shaped snap-fit ​​plates 9 at both ends by sliding it left and right, making it easy to clean the pre-filter plate 10. The filter plates 8 at both ends are removed from the mounting port 7 by the connecting rings 21 at both ends, making it easy to clean the filter plates 8 at both ends. The high-voltage electrostatic sterilization device 11 is separated from the snap-fit ​​slide rail 17 by sliding it left and right, making it easy to maintain the high-voltage electrostatic sterilization device 11.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
