Technical Field

[0001] This utility model relates to the field of air purifier filter technology, specifically to an air purifier filter that is easy to assemble. Background Technology

[0002] Air purifiers, also known as "air cleaners," "air fresheners," or "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. Their most important structure is the filter element in the filtration section.

[0003] Most commonly available filter cartridges on the market require regular cleaning and replacement. Otherwise, dust, hair, and other foreign objects adsorbed on the surface will clog the filter pores, thus affecting the purification effect. The filter section of a conventional air purifier is a complete unit, and the entire filter cartridge needs to be replaced. It is also not easy to clean the dust in the corners and crevices. Utility Model Content

[0004] Therefore, this utility model provides an air purifier filter that is easy to splice. By using the filter element body, it solves the problem that conventional air purifier filter sections are a complete unit, requiring the replacement of the entire filter element, and making it difficult to clean dust from corners and crevices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air purifier filter that is easy to assemble, comprising a filter element body installed inside an air purifier body. The filter element body includes a base plate, and multiple limiting strips are fixedly provided on the top of the base plate. Each of the multiple limiting strips has a limiting groove on one side. A connecting unit and a filter element unit are provided on the top of the base plate. The connecting unit includes a cover plate, and a cavity is provided inside the cover plate. Multiple blocks are fixedly provided inside the cavity. Multiple through holes are provided inside the cover plate. An obstacle avoidance groove is provided on the top of the cover plate. A connecting ring is provided inside the cavity. Multiple limiting blocks are fixedly provided outside the connecting ring. A spring is connected inside the connecting ring. A control block is fixedly provided on the top of the connecting ring. The filter element unit includes a frame, and a filter element is sleeved on the outside of the frame.

[0006] Preferably, the top of the limiting strip plate has a through hole and is slidably connected to the through hole.

[0007] Preferably, the connecting ring is disposed inside the cavity and is slidably connected to the cavity.

[0008] Preferably, the limiting block extends into the limiting groove and is slidably connected to the limiting groove.

[0009] Preferably, the spring is located inside the cavity, with one end of the spring fixedly connected to the connecting ring and the other end of the spring fixedly connected to one side wall of the cavity.

[0010] Preferably, the control block extends through the obstacle avoidance groove and is slidably connected to the obstacle avoidance groove.

[0011] Preferably, the bottom of the keel frame is fixedly connected to the top of the base plate, and the top of the keel frame is in contact with the bottom of the cover plate.

[0012] Preferably, the filter element is fitted onto the outside of the keel frame and slidably connected to the keel frame.

[0013] The present invention has the following advantages:

[0014] 1. By rotating the control block, the connecting ring drives the limiting block to slide out of the limiting groove, and at the same time, the spring spring contracts, releasing the limitation strip plate from the cover plate, thus making it easy to remove the cover plate, so that the top of the filter element is unrestrained, making it easier to replace the filter element individually, and at the same time, the filter element body can be disassembled for separate cleaning, providing a cleaning effect.

[0015] 2. When the lid is placed over the limiting strip, the control block is released. The retracted spring causes the connecting ring to rotate the limiting block into the limiting groove, thus fixing the top of the limiting strip inside the lid. This completes the splicing of the limiting strip and the lid. The splicing and disassembly steps are simple and require no additional tools. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] See attached document Figure 1 - Appendix Figure 6 This utility model provides an air purifier filter that is easy to assemble, including a filter body 2. The filter body 2 is installed inside the air purifier body 1. The filter body 2 includes a base plate 21. Multiple limiting strips 22 are fixedly provided on the top of the base plate 21. Each of the multiple limiting strips 22 has a limiting groove 23 on one side. A connecting unit and a filter unit are provided on the top of the base plate 21. The connecting unit includes a cover plate 31. A cavity 32 is opened inside the cover plate 31. Multiple blocks 33 are fixedly provided inside the cavity 32. Multiple through holes 34 are opened inside the cover plate 31. An obstacle avoidance groove 35 is opened on the top of the cover plate 31. A connecting ring 36 is provided inside the cavity 32. Multiple limiting blocks 37 are fixedly provided outside the connecting ring 36. A spring 38 is connected inside the connecting ring 36. A control block 39 is fixedly provided on the top of the connecting ring 36. The filter unit includes a frame 41. The filter 42 is sleeved on the outside of the frame 41.

[0027] In this embodiment, to facilitate the replacement of filter element 42, when filter element 42 needs to be replaced, filter element body 2 is removed from air purifier body 1, and then control block 39 is pushed to rotate counterclockwise along obstacle avoidance groove 35. The rotation of control block 39 causes limit block 37 to slide out of limit groove 23 through connecting ring 36, and at the same time causes spring 38 to contract, releasing the restriction of limit bar 22 in cover plate 31, thereby making it easy to remove cover plate 31, so that the top of filter element 42 is unrestrained, making it easy to replace filter element 42 individually. At the same time, filter element body 2 can be disassembled for separate cleaning, providing a cleaning effect, preventing cleaning dead corners, and reducing replacement costs.

[0028] To achieve the connection between the base plate 21, the frame 41, and the cover plate 31, the device employs the following technical solution: the top of the limiting strip 22 passes through the through hole 34 and is slidably connected to the through hole 34; the bottom of the frame 41 is fixedly connected to the top of the base plate 21; the top of the frame 41 contacts the bottom of the cover plate 31; the filter element 42 is sleeved on the outside of the frame 41 and is slidably connected to the frame 41; the bottom of the frame 41 is fixed to the top of the base plate 21; the top of the frame 41 contacts the bottom of the cover plate 31; and the top of the limiting strip 22 passes through the through hole 34 and is fixed inside the cover plate 31 by the limiting block 37, thereby fixing the cover plate 31, the frame 41, and the base plate 21 together.

[0029] To achieve the goal of automatically sliding the limiting block 37 into the limiting groove 23 to limit the limiting strip 22, the device employs the following technical solution: a connecting ring 36 is located inside the cavity 32 and is slidably connected to the cavity 32; the limiting block 37 extends into the limiting groove 23 and is slidably connected to the limiting groove 23; a spring 38 is located inside the cavity 32, with one end of the spring 38 fixedly connected to the connecting ring 36 and the other end fixedly connected to one side wall of the cavity 32; a control block 39 passes through the obstacle avoidance groove 35 and is slidably connected to the obstacle avoidance groove 35; when the cover plate 31 is fitted onto the outside of the limiting strip 22 through the through hole 34, the control block 39 is released, and the contracted spring 38, through its elastic force, causes the connecting ring 36 to drive the limiting block 37 into the limiting groove 23, thereby fixing the top of the limiting strip 22 inside the cover plate 31, thus completing the splicing of the limiting strip 22 and the cover plate 31.

[0030] The usage process of this utility model is as follows: When using this utility model, if the filter element 42 needs to be replaced, remove the filter element body 2 from the air purifier body 1, and then push the control block 39 to rotate counterclockwise along the obstacle avoidance groove 35. The rotation of the control block 39 causes the limiting block 37 to slide out of the limiting groove 23 through the connecting ring 36, and at the same time causes the spring 38 to contract, releasing the limitation strip 22 in the cover plate 31, thereby making it easy to remove the cover plate 31, so that the top of the filter element 42 is unrestrained, making it easy to replace the filter element 42 separately. At the same time, the filter element body 2 can be disassembled for separate cleaning, providing a cleaning effect, preventing cleaning dead corners, and reducing replacement costs. The installation is the reverse of the above operation. The disassembly and assembly steps are simple and do not require additional tools.

[0031] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
