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

[0021] Please see Figure 1-3 This utility model provides a technical solution: a filter structure for a household air disinfection and purifier, including a purifier body 1, a support component 7 at the bottom of the inner cavity of the purifier body 1, a limiting frame 8 at the top of the inner cavity of the purifier body 1, a detachable filter component 10 between the support component 7 and the limiting frame 8, and a base 2 on the lower surface of the purifier body 1.

[0022] The filter assembly 10 includes a mounting base frame 101 and a mounting top frame 105. Inside the mounting base frame 101, an inner filter cylinder 110 and an outer filter cylinder 109 are arranged sequentially from the inside to the outside. A connecting ring 103 is threadedly connected to the bottom of the mounting top frame 105. Multiple sets of reinforcing beams 102 are arranged between the connecting ring 103 and the mounting base frame 101. The outer filter cylinder 109 is arranged between the multiple sets of reinforcing beams 102. A side hole 104 is opened on the outer side of the connecting ring 103. A lever 111 that passes through the side hole 104 is threadedly connected to the upper outer side of the outer filter cylinder 109.

[0023] The lower surface of the inner filter cylinder 110 is provided with multiple sets of positioning blocks, and the bottom of the inner cavity of the mounting base frame 101 is provided with positioning holes 112 for the multiple sets of positioning blocks to be embedded. The positioning blocks improve the stability of the inner filter cylinder 110 and prevent the inner filter cylinder 110 from rotating with the outer filter cylinder 109.

[0024] The top frame 105 is internally fixedly connected to an inner ring 106 that communicates with the inner filter cartridge 110. Two sets of ultraviolet disinfection lamps 107 are installed on the inner wall of the inner ring 106. An ion generator 108 is installed in the inner cavity of the inner ring 106. The ultraviolet disinfection lamps 107 are equipped with a photocatalytic purification structure, which is a photocatalytic purification layer with titanium dioxide on it. Under ultraviolet irradiation, it can decompose organic compounds, some inorganic compounds, bacteria and viruses, etc., effectively optimize the air, effectively kill a variety of bacteria, and decompose and harmlessly treat the toxins released by bacteria or fungi. The ion generator 108 is existing technology and will not be described in detail.

[0025] The support assembly 7 includes a chassis 71. A screw sleeve 73 is provided in the middle of the lower surface of the chassis 71. An adjusting bolt 74 is threadedly connected to the lower end of the screw sleeve 73. The adjusting bolt 74 is rotatably located at the bottom of the purifier body 1. A bottom hole is provided at the bottom of the inner cavity of the purifier body 1 for the screw sleeve 73 to slide. The position of the chassis 71 can be easily and quickly adjusted by adjusting the bolt 74, thereby allowing the filter assembly 10 to be disengaged from the limit frame 8, thus improving the efficiency of disassembly and assembly of the filter assembly 10.

[0026] Multiple sets of telescopic rods 75 are fixedly connected to the lower surface of the chassis 71. All sets of telescopic rods 75 are fixedly connected to the bottom of the inner cavity of the purifier body 1. An auxiliary spring 76 is sleeved on the outer side of each set of telescopic rods 75. Multiple sets of anti-detachment blocks 72 are provided on the upper surface of the chassis 71. The springs on the telescopic rods 75 facilitate the reset of the chassis 71. At the same time, the telescopic rods 75 limit the angle of the chassis 71, which facilitates the chassis 71 to drive the filter assembly 10 to rise and fall, thereby improving the installation efficiency of the filter assembly 10.

[0027] The inner cavity of the limiting frame 8 is equipped with a diffusion fan 9. The limiting frame 8 is connected to the inner filter cylinder 110. Multiple air inlets 4 are opened on the outer side of the purifier body 1. The diffusion motor can easily draw outside air into the filter assembly 10, thereby facilitating air filtration.

[0028] The upper surface of the purifier body 1 is provided with a control panel 6, the upper outer side of the purifier body 1 is provided with an air outlet honeycomb mesh cover 5 for air outlet, and the outer side of the purifier body 1 is provided with an openable side door 3. The side door 3 facilitates quick and easy removal and placement of the filter assembly 10, improving the efficiency of disassembling and assembling the filter assembly 10.

[0029] In use, the diffuser fan 9 is activated to draw air out of the inner filter cartridge 110, allowing outside air to enter the purifier body 1 through the air inlet 4. The air first passes through the outer filter cartridge 109, then the inner filter cartridge 110, and finally enters the limiting frame 8. The outer filter cartridge 109 filters large dust particles, while the inner filter cartridge 110 filters and adsorbs small dust particles and odors in the air. The air is then disinfected by the ultraviolet disinfection lamp 107 and then by the ion generator 108, improving the air purification effect. When the filter assembly 10 needs cleaning, the side door 3 is opened, and the purifier body is rotated. The bottom adjusting bolt 74 is used to adjust the height of the chassis 71, generally disengaging the filter assembly 10 from the limiting frame 8, thus facilitating the removal and cleaning of the filter assembly 10. After cleaning, the filter assembly 10 is placed on the chassis 71, and the chassis 71 is raised by rotating the adjusting bolt 74 in the opposite direction, causing the filter assembly 10 to contact the limiting frame 8, thereby completing the installation of the filter assembly 10. The angle of the outer filter cylinder 109 can be adjusted by the lever 111, facilitating the adjustment of the overlap of the filter holes of the inner filter cylinder 110 and the outer filter cylinder 109, thereby facilitating the adjustment of the air purification effect, improving the applicability of the purifier body 1, and enhancing its practicality.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
