[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] The following is combined with Figure 1-7 To further explain this application,

[0039] The present embodiment discloses an air purifier comprising a bottom U-shaped plate 1 and a snap-on filter 4. An air outlet cover 2 is screwed to the top of the bottom U-shaped plate 1. The air outlet cover 2 is provided with two symmetrical air outlets 201. This provides more uniform airflow distribution, avoids the possibility of localized over- or under-flow caused by single-point air outlet, and improves indoor air quality. Air inlet covers 3 are snapped onto both sides of the bottom U-shaped plate 1.

[0040] There are two snap-on filters 4, which are located on the inner sides of the air inlet cover 3 on both sides;

[0041] Upward-bent protrusions 101 are provided on both sides of the bottom of the U-shaped plate 1. Mounting blocks 8 that mate with and plug into protrusions 101 are located on the bottom wall of the U-shaped plate 1 and located inside protrusions 101. Protrusions 101 are screwed to the mounting blocks 8 via screws extending through them. This increases the stability and strength of the structure while facilitating the installation and removal of the mounting blocks 8, improving the overall reliability of the product. Mounting blocks 8 are provided with open slots 801 that mate with protrusions 101 for insertion and positioning. This allows for more precise alignment between the mounting blocks 8 and protrusions 101, facilitating quick positioning and securing of the mounting blocks 8. Furthermore, protrusions 101 limit the mounting blocks 8, preventing them from shifting or loosening, thereby improving installation efficiency.

[0042] Mounting block 8 defines a transverse concave groove 802. Springs 5 ​​are arranged at equal intervals within concave groove 802, with one end of the spring 5 secured to the bottom wall of concave groove 802 and the other end secured to the bottom of positioning groove 6. The even distribution of springs 5 ​​helps evenly secure the snap-on filter 4, reducing damage to the snap-on filter 4 caused by uneven pressure and providing a better filtering effect. By pressing on the snap-on filter 4, the springs 5 ​​are compressed, allowing the snap-on filter 4 to move downward for removal, facilitating installation and removal of the snap-on filter 4.

[0043] The bottom of the snap-on filter 4 is inserted into the positioning groove 6 supported by the spring 5, and the top of the snap-on filter 4 is limited and abutted under the baffle 7. The positioning groove 6 cooperates with the concave groove 802 to guide the insertion. This ensures the precise positioning and guidance of the snap-on filter 4, simplifies the installation process, reduces installation errors, and improves the assembly quality of the product.

[0044] The snap-on filter screen 4 is positioned and snapped onto the inner side of the bottom U-shaped plate 1 from the upper and lower ends of the snap-on filter screen 4 through the cooperation of the baffle 7 and the positioning groove 6, and after the snap-on filter screen 4 is snapped, the left and right sides of the snap-on filter screen 4 are tightly pressed against the inner wall of the bottom U-shaped plate 1.

[0045] The snap-on filter 4 includes a frame 401 that fits into the positioning slots 6 and a filter cloth 402 fixed to the inside of the frame 401. Two positioning pins 403 are located on either side of the top of the frame 401. The design of the frame 401 makes the filter more stable, and the positioning pins 403 ensure that the snap-on filter 4 is accurately installed and not easily removed.

[0046] The baffle 7 includes an integrally formed side panel 701, a limiting plate 702 located at the top of the side panel 701, and mounting panels 703 located on both sides of the side panel 701; a ventilation hole 704 is provided on the side panel 701; the mounting panel 703 is mounted on the bottom U-shaped plate 1 by bolts, and the side panel 701 cooperates with the side of the snap-on filter 4 to limit the top position. The integrally formed design improves the integrity and strength of the structure, and the ventilation hole 704 helps to disperse the airflow, reduce noise, and improve air circulation. The limiting plate 702 limits the top of the frame 401, and the positioning pin 403 at the top of the frame 401 is inserted into the U-shaped slot 705 provided on the limiting plate 702. This design provides a dual fixing mechanism to ensure the stability of the snap-on filter 4 at the top position and avoid displacement of the snap-on filter 4 during operation.

[0047] Compared with the air inlet cover 3 and the filter plate 100 fixed by bolts, the air purifier adopts the design of snap-on filter 4 and snap-on air inlet cover 3, which allows the user to quickly install and replace the filter without using tools, thereby improving user convenience. The snap-on design simplifies the operating steps, and the user only needs to gently operate to complete the installation and removal of the filter, which reduces technical requirements. Since no additional screws and tools are required, the snap-on design can reduce maintenance costs, while reducing repair costs caused by damaged or lost screws.

[0048] After the snap-on filter 4 is snapped on, the left and right sides are tightly pressed against the inner wall of the bottom U-shaped plate 1. The snap-on design can ensure the sealing between the filter and the air inlet cover 3, prevent air leakage, and thus improve the purification efficiency.

[0049] The snap-on filter 4, combined with the positioning slots 6 and baffle 7, enhances overall stability and prevents structural instability caused by loose screws. This design reduces the use of screws, thereby reducing problems caused by screw fatigue and corrosion, and improving product durability. If the filter needs to be upgraded in the future, the snap-on design allows for quick replacement of components.

[0050] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
