Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air purification devices, and more specifically, to a primary filter structure and a pet air purifier. Background Art
[0002] Pet hair shedding is likely to float in the air and cause harm when inhaled into the lungs. In addition, if the pet's excrement is not cleaned up in time during excretion, it will emit odors and pollute the indoor air. Therefore, more and more pet-owning families are equipped with pet air purifiers to purify the indoor air. An air purifier generally uses a primary filter to conduct primary filtration on dust particles larger than 5 μm in the air. During the purification process, the filter adsorbs pet hair and dust to filter the air. Long-term attachment of pet hair to the filter will breed bacteria. Therefore, the filter needs to be replaced and cleaned regularly to maintain the purification effect. When replacing the filter, the hand is easily in contact with the filter, and the bacteria bred on the filter are easily adhered to the hand, which is not conducive to human health.
[0003] In view of this, the applicant has put forward this application after studying the existing technologies. Summary of the Utility Model
[0004] The utility model provides a primary filter structure and a pet air purifier, aiming to improve at least one of the above technical problems.
[0005] To solve the above technical problems, the utility model provides a primary filter structure, which includes an upper cover, a support frame, and a filter. The upper cover is joined to the support frame through a rotating shaft to form an openable and closable box body. A plurality of inclined upward grid bars are arranged in parallel on the top of the upper cover. The bottom of the support frame is hollowed out so that air flow can pass through the box body. The filter is placed inside the box body. The support frame is connected with an openable and closable sewage discharge cover on a side wall adjacent to one of the rotating shafts, so that when the sewage discharge cover is opened, the filter can slide out of the box body by inclining the box body.
[0006] As a further optimization, the upper cover is provided with an elastic sheet on a side opposite to the rotating shaft, and the support frame is provided with a buckle adapted to the elastic sheet on a side opposite to the rotating shaft. The box body is fixed and closed through the cooperation of the elastic sheet and the buckle.
[0007] As a further optimization, the bottom of the support frame is constructed as a grid structure.
[0008] As a further optimization, the sewage discharge cover is provided with a handle, and the handle is provided with a magnet. The side wall of the support frame is provided with an adsorption strip adapted to the magnet, so that the sewage discharge cover can be fixed by magnetic attraction when it is closed.
[0009] As a further optimization, the handle is disposed in the middle of the sewage cover, and grooves are provided on the side walls of the upper cover and the support frame at positions corresponding to the handle, so that when the sewage cover is closed, the handle can be placed in the groove.
[0010] As a further optimization, a horizontal bar is provided at the middle position of the top of the upper cover, the inclined directions of the grid bars on both sides of the horizontal bar are opposite, and the handle protrudes above the horizontal bar.
[0011] As a further optimization, the upper cover is made of a transparent material.
[0012] As a further optimization, the filter screen is electrostatic cotton.
[0013] As a further optimization, it further includes a housing, the box body is disposed in the housing, and an air outlet is provided on the housing, which includes a combined air cover and a base.
[0014] This application further provides a pet air purifier, including the primary filter structure described in any one of the above.
[0015] By adopting the above technical solutions, the following technical effects can be achieved by the present utility model:
[0016] In a primary filter structure of this application, a box body is formed by an upper cover and a support frame joined by a rotating shaft, a filter screen is placed in the box body, and a plurality of inclined upward grid bars are arranged in parallel on the top of the upper cover to form a grid structure. A sewage cover is opened on the side wall of the support frame. When replacing the filter cotton, open the sewage cover on the side wall and tilt the box body, and the filter screen can be directly poured into the garbage bag without touching the contaminated filter screen with the hand. The design of the inclined upward grid bars can further prevent the user's hand from contacting the pollution source, realizing contactless replacement and preventing bacteria on the contaminated filter screen from sticking to the hand, which is not conducive to health.

[0025] Embodiment 1
[0026] As Figures 1 to 4 shown, the embodiment of the present utility model provides a primary filter structure, including an upper cover 1, a support frame 2 and a filter net 3. The upper cover 1 is joined to one side wall of the support frame 2 through a rotating shaft, so that the two form an openable and closable box body. A plurality of grid bars 11 inclined upward are arranged in parallel on the top of the upper cover 1 to form a grid structure. The bottom of the support frame 2 is hollowed out, so that air flow can pass through the box body. Among them, the hollowed-out structure at the bottom of the support frame 2 is preferably a grid structure; the grid bars 11 inclined upward, the filter net 3 is placed in the box body, so that the air can be filtered when passing through the box body; in this application, the filter net preferably uses electrostatic cotton, and an adsorption layer can be added to the electrostatic cotton. The adsorption layer can be designed as a pet pattern to enhance the recognition of the filter net for pet air purifiers. The support frame 2 is connected with an openable and closable sewage cover 4 on one side wall adjacent to one of the rotating shafts. The two ends of the sewage cover 4 can be connected to the support frame 2 through shaft pins. When the sewage cover 4 is opened, the filter net 3 can be slid out of the box body by tilting the box body.
[0027] Specifically, on one side of the upper cover 1 opposite to the rotating shaft, there is a elastic sheet 12, and on one side of the support frame 2 opposite to the rotating shaft, there is a buckle 21 adapted to the elastic sheet 12. The box body is fixed and closed through the cooperation of the elastic sheet 12 and the buckle 22. The sewage discharge cover 4 is provided with a handle 41 at the middle position, and a magnet 42 is provided on the handle 41. An adsorption strip adapted to the magnet 42 is provided on the side wall of the support frame 2, so that the sewage discharge cover 4 can be fixed by magnetic adsorption when closed. Grooves 5 are provided on the side walls of the upper cover 1 and the support frame 2 at positions corresponding to the handle 41. The adsorption strip is arranged in the groove on the support frame 2, so that when the sewage discharge cover 4 is closed, the handle 41 can be placed in the groove 5 to prevent the handle from protruding from the side wall of the box body. A cross bar 13 is provided at the middle position on the top of the upper cover 1. The inclined directions of the grid bars 11 on both sides of the cross bar 13 are opposite. The handle 41 is higher than the cross bar 13, which is convenient for the user to open the sewage discharge cover 4.
[0028] Embodiment 2
[0029] Refer to Figure 4 and Figure 5 As shown, an outer shell can be configured outside the box body. The outer shell is formed by joining a wind cover 6 and a base 7. An air outlet 8 is provided on the outer shell, and the base 7 can be connected to the pet air purifier. When replacing, open the wind cover 6, take out the box body, then open the sewage discharge cover 4, tilt the box body and directly pour the contaminated filter net 3 into the trash can. After that, open the upper cover 1, install a new filter net, and close the upper cover 1 and the sewage discharge cover 4 to complete the replacement, without the need to touch the contaminated filter net by hand, realizing contactless replacement. In this application, the upper cover 1 can be made of a transparent material, enabling the user to clearly see the pet hair adsorbed by the filter net and making the user perceive the effectiveness of the product.
