[0013] Preferably, the two rotating shafts are rotatably connected to a fixing plate fixed to an inner wall of one side of the box body, and one end of one of the rotating shafts is connected to a servo motor installed on the fixing plate.

[0014] The rotating shaft on the rotating shell is rotatably supported by the fixing plate, and the output shaft of the servo motor drives the rotating shaft to rotate, thereby rotating the rotating shell.

[0015] Preferably, the spherical tube and the filter cartridge form a plug-in fit, and the outer diameter of the spherical tube is larger than the inner diameter of the filter cartridge, and one end of the fixing rod away from the spherical tube is fixed to the inner wall of the box body.

[0016] The spherical tube is plugged and connected with the filter cartridge, so that air can circulate in the entire dust removal mechanism.

[0017] Preferably, a dust hood is inserted into one end of one of the connecting tubes away from the spherical tube, and a built-in fan is installed in the other connecting tube.

[0018] The air is circulated by a built-in fan in the connecting pipe, and the suction hood expands the suction of external air by the connecting pipe.

[0019] The beneficial effects of the utility model are:

[0020] The servo motor drives the rotating shell to rotate. During the rotation of the rotating shell, the connecting components on both sides are pushed, and the connecting tube and the spherical tube move away from the rotating shell, causing the telescopic spring to elastically contract. When the rotating shell rotates to align the next filter cartridge with the spherical tube, the telescopic spring pushes the connecting tube close to the rotating shell, causing the spherical tube to dock with the filter cartridge. The filter cartridge to be cleaned moves to the outside of the box as the rotating shell rotates, which is convenient for taking out and cleaning the filter cartridge. The problem that the dust bag in the prior art is easily blocked due to excessive dust and needs to be replaced frequently, and the machine needs to be stopped and disassembled for replacement, which is inconvenient.
