[0031] To describe the technical content, achieved purposes and effects of the present utility model in detail, the following is described in conjunction with embodiments and accompanied by drawings.

[0032] Currently, the adsorption effect of air purifiers on pet hair is insufficient and cannot meet the needs of pet-owning people.

[0033] Based on this, please refer to Figures 1 to 8 , the present utility model provides a housing 21, including a long-strip air inlet 211, the air inlet 211 is arranged on the side wall of the housing 21, and the air inlet 211 is distributed along the height direction of the housing 21. Setting a long-strip air inlet along the height direction on the housing can make the air enter the housing tangentially, concentrate the inhaled air flow, increase the suction force, and effectively improve the adsorption effect on pet hair.

[0034] Specifically, the air inlet 211 can be rectangular or oblong. Such a setting enables the air inlet 211 to facilitate the entry of hair into the interior of the housing 21 along the air inlet 211, effectively preventing pet hair from sticking to the air inlet 211, and avoiding the blockage of the air inlet 211 during long-term use.

[0035] In some embodiments, a notch is formed on the side wall of the housing 21, and an arc-shaped diversion piece 212 is arranged in the notch;

[0036] In the circumferential direction of the housing 21, the arc-shaped diversion piece 212 extends from one side of the notch to the other side of the notch, so that an air inlet 211 is formed between the arc-shaped diversion piece 212 and the side wall of the housing. During use, after the internal components of the housing 21 drive the air to flow, the air entering the air inlet 211 flows along the surface of the arc-shaped diversion piece 212, forming a negative pressure structure, increasing the suction force on the hair, and effectively improving the adsorption ability of pet hair. Further, the arc-shaped diversion piece 212 is integrally distributed in a spiral shape on the housing 21, further enhancing the adsorption ability of pet hair.

[0037] Please refer to Figures 1 to 8, the present utility model further provides a filtering component 1, which is disposed inside the housing 21 as described above arbitrarily. The projection area of the filtering component 1 on the side wall of the housing 21 covers the air inlet 211. That is, the air inlet 211 of the housing 21 entirely surrounds the filtering component 1 in the height direction. Within the height range of the air inlet 211 and the filtering component 1, the air entering the housing 21 along the air inlet 211 can directly contact the filtering component 1, accelerating the contact speed, avoiding the settlement and accumulation of hair during the flow process, and avoiding the occurrence of clogging problems.

[0038] In some embodiments, it includes a filter element 12 and a filter mesh 11. The filter mesh 11 is detachably disposed on the air inlet surface of the filter element 12, and the filter mesh 11 is an overall wavy three-dimensional mesh structure.

[0039] The filter mesh 11 adopts an overall wavy three-dimensional mesh structure, which can increase the surface area of the filter mesh 11 within a limited space, better collect hair, and prevent the hair from adhering to the filter element 12. At the same time, the detachable design enables the filter mesh 11 and the filter element 12 to be separated and cleaned, which is convenient to use.

[0040] It can be understood that a detachable filter mesh 11 is disposed on the air inlet surface of the filter element 12. The filter mesh 11 can block pet hair from entering the filter element 12 when the filter element 12 purifies the air. The detachable design is convenient for users to clean the filter mesh 11. At the same time, the wavy three-dimensional mesh structure can increase the specific surface area of the filter mesh 11, block a large amount of pet hair, extend the cleaning interval, and effectively improve the user experience.

[0041] In some embodiments, the material of the filter mesh 11 is electret fiber. Specifically, the electret fiber enables the filter mesh 11 to obtain electrostatic adsorption ability, which can improve the adsorption ability of the filter mesh 11 to hair and enhance the interception effect of the filter mesh 11 on hair.

[0042] In some embodiments, the filter mesh 11 is formed by interweaving a plurality of fiber filaments with each other. The filter mesh 11 adopts the way of interweaving electret fibers, which can obtain a single-layer three-dimensional mesh structure. It not only occupies a small area, but also enables the filter mesh 11 to bend and deform without changing the three-dimensional structure, can be cleaned daily, and can adapt to the shapes of different filter elements 12.

[0043] In some embodiments, the filter element 12 is a hollow cylindrical shape. The outer surface of the filter element 12 is the air inlet surface, and the inner surface of the filter element 12 is the air outlet surface. The filter element 12 adopts a cylindrical structure, which can obtain a larger air inlet surface and improve the purification range. Specifically, when the filter mesh 11 is unfolded, it is a planar mesh structure. At least one end in the length direction of the filter mesh 11 is provided with a connecting member, so that the filter mesh 11 is connected end to end and sleeved on the surface of the filter element 12.

[0044] Please refer to Figures 1 to 8, the present utility model also provides an air purifier 2, which includes a driving component 22 and the filtering component 1 as described above; the driving component 22 is arranged inside the housing 21, an air outlet 213 is provided at the top of the housing 21, and the driving component 22 is communicated with the air outlet surface of the filtering component 1 and the air outlet 213. The air purifier 2 uses the filtering component 1 with a detachable filter screen 11, and the driving component 22 drives the air to flow, so that the air in the space enters the filtering component 1 through the housing 21 and is purified and discharged. It can not only handle conventional particulate matter, but also intercept pet hair, expanding the usage environment of the air purifier 2.

[0045] In some embodiments, the driving component 22 includes a driving motor 221 and an impeller 222, and the impeller 222 is arranged at the output end of the driving motor 221. The driving motor 221 directly drives the impeller 222 to rotate, ensuring the stability of the overall suction intensity.

[0046] In some embodiments, it further includes a flow guide cover 223, and the driving motor 221 and the impeller 222 are arranged inside the flow guide cover 223. The flow guide cover 223 can make the air flow formed by the driving motor 221 and the impeller 222 more concentrated, enhancing the adsorption effect while reducing noise and improving the user experience.

[0047] In some embodiments, it further includes a fixed grille 23, and the fixed grille 23 is arranged between the driving component 22 and the filtering component 1. The fixed grille 23 fixes the driving component 22 and the filtering component 1 in the housing 21 respectively without affecting the air flow transportation effect, facilitating the user to clean or repair the driving component 22 and the filtering component 1 separately.

[0048] Please refer to Figures 1 to 8 , Embodiment 1 of the present utility model is:

[0049] An air purifier 2, which includes a housing 21, a driving component 22 and a filtering component 1;

[0050] The housing 21 is provided with a long-strip air inlet 211, and the air inlet 211 is arranged on the side wall of the housing 21 along the height direction of the housing 21. The air inlet 211 is provided with an arc-shaped drainage piece 212, and the arc-shaped drainage piece 212 extends from the air inlet 211 into the interior of the housing 21. The driving component 22 and the filtering component 1 are arranged inside the housing 21, and the driving component 22 is communicated with the air outlet surface of the filtering component 1 and the air outlet 213.

[0051] The filtering component 1 includes a filter element 12 and a filter screen 11, and the filter screen 11 is detachably arranged on the air inlet surface of the filter element 12. The filter screen 11 is an overall wavy three-dimensional mesh structure.

[0052] In this embodiment, the filter screen 11 is formed by fiber interweaving, and the material of the filter screen 11 is electret fiber.

[0053] The working principle of the present utility model is as follows: The drive motor 221 of the drive assembly 22 drives the impeller 222 to rotate at a high speed, causing the air flow to enter the filter assembly 1 along the air inlet 211 of the housing 21 and flow out from the air outlet 213. The rectangular air inlet 211 and the diversion pieces form a relatively large negative pressure air flow structure, causing pet hair to float up and enter the housing 21 together with the air flow, and being adsorbed and intercepted by the filter screen 11 formed by the interweaving of electret fibers. The remaining air enters the filter element 12, is adsorbed by the filter element 12, and is discharged from the air outlet 213 of the housing 21.

[0054] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in the relevant technical fields, shall be included in the patent protection scope of the present utility model by the same token.
