Under the action of the bolts, the filter box 1 can be in contact with the external ceiling, so that the inlet 2 is connected with the external air inlet;

[0043] A pair of outlets 3 are formed in two side walls of the filter box 1;

[0044] A square groove 4 is formed on the inner upper end surface of the filter box 1 and is located outside the inlet 2;

[0045] The filter cartridge 5 is arranged in the filter box 1, and the top end is plugged into the square groove 4;

[0046] An opening is formed in a side wall of the filter cartridge 5;

[0047] A filter 6 is arranged in the opening;

[0048] The filter screen 6 is fixedly installed in the opening and can be kept fixed, and the filter screen 6 can filter the gas entering the inlet 2;

[0049] A lifting mechanism is provided on the inner lower end surface of the filter box 1 and is used to carry the filter cartridge 5;

[0050] A rotating shaft 7 is rotatably mounted in the outlet 3;

[0051] A sealing plate 8 is provided on the outer surface of the rotating shaft 7;

[0052] The sealing plate 8 is fixedly mounted on the outer surface of the rotating shaft 7 and can be relatively fixed. At the same time, the rotation of the rotating shaft 7 can drive the sealing plate 8 to flip, so that it seals the outlet 3 to prevent external dust from entering the filter box 1;

[0053] The driving mechanism is arranged on the outer wall surface of the filter box 1 and is used for driving the rotating shaft 7 to rotate.

[0054] Specifically, the lifting mechanism includes:

[0055] The lifting plate 9 is arranged in the filter box 1, and the upper end surface of the lifting plate 9 contacts the lower end surface of the filter cartridge 5;

[0056] The limiting groove 10 is formed in the inner lower end surface of the filter box 1;

[0057] The limiting rod 11 is fixedly mounted on the lower end surface of the lifting plate 9 and is slidably connected to the limiting groove 10;

[0058] The screw rod 12 is disposed on the lower wall of the filter box 1, and one end of the screw rod is rotatably connected to the lower end surface of the lifting plate 9, and the other end of the screw rod is provided with a handle;

[0059] The screw 12 is threadedly connected to the lower wall of the filter box 1. When the staff turns the handle, the screw 12 can be driven to rotate at the same time, which can drive the lifting plate 9 to rise, so that the filter cartridge 5 it carries can move at the same time. When the lifting plate 9 moves, it can drive the limiting rod 11 to slide outside the limiting groove 10. Under the action of the limiting groove 10 and the limiting rod 11, the lifting plate 9 can be made more stable when moving.

[0060] Specifically, the driving mechanism includes:

[0061] A pair of worm gears 13 are provided on one side of the filter box 1 and are fixedly connected to one end of a pair of rotating shafts 7 respectively;

[0062] A pair of fixing blocks 14 are arranged on the outer wall of the filter box 1;

[0063] The worm 15 has two ends that penetrate through a pair of fixing blocks 14 and are meshed with a pair of worm wheels 13;

[0064] A driving member 16 is provided on the outer wall surface of the filter box 1;

[0065] A pair of sprockets 17 are fixedly connected to the outer surface of the worm 15 and the output end of the driving member 16 respectively;

[0066] The chain 18 is meshed and connected with a pair of sprockets 17;

[0067] The driving member 16 is a motor, and the rotation of its output end can drive a sprocket 17 to rotate at the same time. At this time, under the action of the chain 17, another sprocket 17 and the worm 15 can be driven to rotate at the same time. The rotation of the worm 15 can respectively drive a pair of worm wheels 13 to rotate at the same time. At this time, the rotation of a pair of worm wheels 13 can respectively drive a pair of rotating shafts 7 to rotate at the same time.

[0068] Specifically, a sealing gasket 19 is provided on the inner upper end surface of the square groove 4, and the upper end surface of the filter cartridge 5 contacts the outer surface of the sealing gasket 19;

[0069] The sealing gasket 19 is bonded to the inner upper end surface of the square groove 4 , and can seal the gap between the square groove 4 and the filter cartridge 5 .

[0070] Specifically, a sealing door 20 is hingedly connected to one side wall of the filter box 1;

[0071] When the sealing door 20 is flipped closed, the filter box 1 can be sealed. When it is flipped open, it is convenient for the staff to collect the filter cartridge 5 and clean the dust on the filter screen 6.

[0072] Working principle: When in use, the staff starts the driving member 16, and the output end of the driving member 16 rotates to drive a sprocket 17 to rotate at the same time. At this time, under the action of the chain 17, another sprocket 17 and the worm 15 can be driven to rotate at the same time. The rotation of the worm 15 can respectively drive a pair of worm wheels 13 to rotate at the same time. At this time, the rotation of the pair of worm wheels 13 can respectively drive a pair of rotating shafts 7 to rotate at the same time. At this time, the rotation of the rotating shaft 7 can drive the sealing plate 8 to flip and open the outlet 3. At this time, the external gas enters the filter cartridge 5 from the inlet 2, and the filter screen 6 filters it. The filtered gas is then discharged from the outlet 3 to prevent indoor air pollution. When it is necessary to clean the dust in the filter cartridge 5, the staff flips the sealing door 20, opens the filter box 1, and turns the handle at the same time to drive the screw 12 to rotate, so that the lifting plate 9 moves downward, so that the upper end of the filter cartridge 5 can be disengaged from the square groove 4, which is convenient for the staff to take out the filter cartridge 5, clean the dust in the filter cartridge 5 and clean the filter screen 6. At the same time, when not in use, the staff starts the driving member 16 to flip its output end, so that the rotating shaft 7 drives the sealing plate 8 to flip and seal the outlet 3 to prevent external dust from entering the filter box 1 from the outlet 3 and polluting the space inside the filter box 1, bringing convenience to people.
