Embodiment 1
[0045] During the implementation of the technical solution of the present application, the initial state of the device is as follows figure 1 As shown, at this time, the pneumatic rod is in the rising state under the action of the spring, the magnet is far away from the Hall switch, the Hall switch is disconnected, and the fan does not work when the power is off; The controller starts the electric air pump, at this time the electric air pump pumps high-pressure air into the air intake pipe through the L-shaped pipe, the high-pressure air enters the connecting pipe and the exhaust pipe through the four-way pipe, and the high-pressure air is blown in through several air holes in the exhaust pipe The distribution box blows up the dust in the distribution box, and the blown dust finally falls on the bottom surface of the insulating inner shell and slides along the bottom surface to the vicinity of the suction pipe. At the same time, the high-pressure airflow enters the next four T...
Embodiment 2
[0047] The magnet on the lower end face of the pneumatic rod is removed, and the Hall switch is replaced by a button switch or a pressure switch, and the others are the same as in Embodiment 1.
