A cleaning component is provided on the side of the back plate 051 near the second installation cavity 021.

[0026] See also Figure 1 and Figure 3 In this embodiment, in order to better install and fix the filter cartridge 04, support feet 014 are provided at the four corners of the bottom end of the outer box body 01, and a limit ring 022 is provided at a position of the inner wall of the first installation cavity 02 near the second installation cavity 021. The exhaust fan 011 is installed at a position of the inner wall of the first installation cavity 02 near the top, and the fence 012 is provided at a position above the exhaust fan 011 on the inner wall of the first installation cavity 02. When the filter cartridge 04 is installed, its top end will contact the limit ring 022 under the push of the spring 034 and the movable chassis 03, thereby completing the installation and fixation. The exhaust fan 011 will discharge air upward, and draw the outside air into the filter cartridge 04 through the air inlet 013, and then pass through the filter cartridge 04 from the first installation cavity 02 through the exhaust fan 011 to be discharged;

[0027] The movable cavity 032 is opened at the bottom of the inner cavity of the second installation cavity 021 and a limiting flange is provided on the inner wall of the movable cavity 032 near the top. The movable chassis 03 is movably clamped between the interior of the movable cavity 032 and the limiting flange. The flange is used to limit the movable chassis 03 in the movable cavity 032, and cooperates with the spring 034 to enable the movable chassis 03 to move up and down within a certain range in the movable cavity 032, and exert an upward force on the filter cartridge 04.

[0028] See also Figure 1 and Figure 3 It should be noted that, in order to better adjust the orientation of the filter cartridge 04, there are several mounting cartridges 033 and they are respectively arranged at the bottom of the inner cavity of the movable cavity 032, the number of springs 034 corresponds to the number of mounting cartridges 033 and they are respectively arranged in the inner cavity of the mounting cartridges 033, and the height of several springs 034 protrudes from the mounting cartridges 033 and contacts the bottom end surface of the movable chassis 03;

[0029] The adjusting groove 036 is opened at the center of the bottom end of the outer box body 01, and the handle 037 is arranged in the adjusting groove 036. The bottom end of the connecting rod 035 is connected to the handle 037 and the top end passes through the outer box body 01 and the movable cavity 032 and is connected to the center position of the bottom end surface of the movable chassis 03. There are several limit sleeves 031, which are respectively arranged at the top of the movable chassis 03. The number and position of the limit blocks 041 correspond to the limit sleeves 031 and are respectively arranged on the outside of the filter cartridge 04 near the bottom end. The limit sleeve 031 is fixedly connected to the movable chassis 03, and the limit block 041 is fixedly connected to the filter cartridge 04. The limit sleeve 031 is designed as an n-shaped structure and the size of the groove matches the limit block 041.

[0030] When installing the filter cartridge 04, first align the limit block 041 on the outer side of the bottom end of the filter cartridge 04 with the limit sleeve 031 on the movable chassis 03 and snap it in, then press the filter cartridge 04 downward, so that the movable chassis 03 moves down to compress the spring 034. After pressing down, the top of the filter cartridge 04 is snapped in from the bottom of the first installation cavity 02 and rests under the limit ring 022 to complete the installation. When it is necessary to adjust the position of the filter cartridge 04 from the outside, first grasp the handle 037 and rotate it to drive the connecting rod 035 and the movable chassis 03 to rotate in the movable cavity 032, thereby using the movable chassis 03 to drive the limit sleeve 031 and the limit block 041 to rotate, thereby driving the filter cartridge 04 to rotate and adjust the position.

[0031] See also Figure 1 and Figure 4Specifically, in order to better clean the dust on the outer surface of the filter cartridge 04, the cleaning assembly includes an adjustment plate 06, a fixed plug rod 061, a connecting block 062, a vertical rod 063 and bristles 064. Blocks 052 are provided at the central positions of the top and bottom ends of the back plate 051. Slots 05 that fit the block 052 are provided at positions on the back of the outer box body 01 that correspond to the block 052. The connecting block 062 is fixedly connected to the back plate 051.

[0032] There are two adjustment plates 06 and they are respectively arranged on one side of the back plate 051 close to the second installation cavity 021. One end of the connecting block 062 is rotatably connected to the inner side of the adjustment plate 06. The fixed plug rod 061 passes through the adjustment plate 06 and is movably plugged into the top of the connecting block 062. The vertical rod 063 is arranged on the side of the top of the connecting block 062 away from the adjustment plate 06.
