Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Example 1

[0030] The fans 7 are arranged in two groups, in one group, the air is taken in by the air duct 1 6 and the air is discharged by the air duct 2 8, and an air filter plate 24 is arranged in the air duct 1 6, and in the other end group, the air is discharged by the air duct 1 6 and the air is taken in by the air duct 2 8, and no air filter plate 24 is arranged in the air duct 1 6.

[0031] When in use, the motor 12 simultaneously drives the two fans 7 to rotate in opposite directions, so that the air duct 1 6 provided with an air filter plate 24 takes in air from the air duct 1 6 and exhausts air from the air duct 2 8, and the air duct 1 6 not provided with an air filter plate 24 exhausts air from the air duct 1 6 and takes in air from the air duct 2 8. One group of fans 7 generates negative pressure in the air duct 1 6 and positive pressure in the air duct 2 8, and the other group of fans 7 generates positive pressure in the air duct 1 6 and negative pressure in the air duct 2 8, thereby rotating the blocking plate 9, and separating the blocking plate 9 from the magnetic body 10. When the fans 7 stop rotating, the blocking plate 9 is in a vertical state under the action of gravity, and the magnetic force generated by the magnetic body 10 attracts the blocking plate 9, thereby keeping the blocking plate 9 in a vertical state.

[0032] The device is provided with a magnetic body 10, and the magnetic force generated by the magnetic body 10 is used to attract the sealing plate 9, so that when the fan 7 is not in operation, the sealing plate 9 has a sealing effect on the air inlet and outlet of the air supply component 3, thereby solving the defect that smaller pollutants will enter the air outlet hood through the circular hole and be absorbed by the activated carbon when the device is not in operation, thereby increasing the service life of the air filter plate 24.

[0035] The device is provided with a bevel gear 13, which drives the bevel gear 3 15 and the bevel gear 2 14 to rotate simultaneously, so that the two fans 7 rotate at the same time, so that the two fans 7 rotate in opposite directions and reduce the power mechanism, thereby reducing the cost of the device.

[0036] like Figure 1 As shown, the fixing mechanism 2 includes a ring 18 and a sponge block 19, one side of the sponge block 19 is fixedly connected to the side of the ring 18, and a plurality of suction cups 20 are fixedly connected to the side of the ring 18 in a circular array; the ring 18 of one group of fixing mechanisms 2 is fixedly connected to the outer surface of the barrel 1, and the inner surface of the ring 18 of another group of fixing mechanisms 2 is fixedly connected to a plurality of plug-in blocks 22 in a circular axis array, and the surface of the gear box 11 is provided with a plug-in groove 21 adapted to the plug-in block 22.

[0037] The device is provided with a suction cup 20. The suction cup 20 of the fixing mechanism 2 fixed on the surface of the drum 1 first sucks the fixing surface, and then the plug-in block 22 of another group of the fixing mechanism 2 is inserted into the plug-in groove 21 on the surface of the drum 1, so that the suction cup 20 of the other group is also adsorbed on the fixing surface. Since the plug-in block 22 can slide back and forth in the plug-in groove 21, the device can be fixed on the fixing surface of different thicknesses, thereby increasing the applicability of the device.

[0038] Working principle: insert the drum 1 into the hole opened on the fixed surface, and make the suction cup 20 of the fixing mechanism 2 fixed on the surface of the drum 1 suck the fixed surface first, and then insert the plug-in block 22 of the other set of fixing mechanism 2 into the plug-in groove 21 on the surface of the drum 1, so that the suction cup 20 of the other set is also adsorbed on the fixed surface, and use the bevel gear 13 to drive the bevel gear 3 15 and the bevel gear 2 14 to rotate at the same time, so that the two fans 7 rotate at the same time and in opposite directions, so that the air filter plate 24 is set in the air duct 1 6, and the air enters from the air duct 1 6 and the air enters from the air duct 2 8 for air outlet, no air filter plate 24 is provided in air duct one 6, air is discharged from air duct one 6 and air is taken in from air duct two 8, one group of fans 7 generates negative pressure in air duct one 6 and positive pressure in air duct two 8, and another group of fans 7 generates positive pressure in air duct one 6 and negative pressure in air duct two 8, thereby rotating the blocking plate 9, and separating the blocking plate 9 from the magnetic body 10, when the fans 7 stop rotating, the blocking plate 9 is in a vertical state under the action of gravity, and the magnetic force generated by the magnetic body 10 attracts the blocking plate 9, thereby keeping the blocking plate 9 in a vertical state.

When the motor 12 rotates, the magnetic body 10 stops supplying power, and when the motor 12 does not rotate, the magnetic body 10 is powered, thereby making the opening and closing of the blocking plate 9 more reliable.

[0042] Working principle: The processing module 4 is used to simultaneously control whether the motor 12 rotates and whether the magnetic body 10 is powered.
