[0022] Furthermore, the cylinder body of the electric drum 1 is made of galvanized carbon steel, and is provided with a sprocket to drive a steel mesh.

[0023] Specifically, the electric roller 1 is the active part of the system, between the left support plate 2 and the right support plate 3, the left support plate 2 is on the left part of the system and the right support plate 3 is on the right part of the system, playing a supporting and fixing role, the driving gear 4 is located between the electric roller 1 and the left support plate 2, the rotary encoder 5 system is installed on the left support plate 2, and the driver of the electric roller 1, the rotary encoder 5 system and the controller of the device are electrically connected.

[0024] Furthermore, the left support plate 2 is composed of a support plate 2.1 and a bearing 2.2. The support plate 2.1 is made of 45 steel with a galvanized surface. The bearing 2.2 should be compatible with the encoder sleeve shaft 5.2 constituting the rotary encoder system 5.

[0025] Furthermore, the material 3 of the right support plate is 45 steel with a galvanized surface.

[0026] Furthermore, the driving gear 4 is made of 45 steel with a galvanized surface, and its inner hole is adapted to the supporting shaft of the electric drum 1 and is adapted to the driven gear 5 . 1 of the rotary encoder system 5 .

At this time, the filter screen can effectively filter the air. When the controller determines that the filtered air is abnormal, the controller controls the electric drum 1 and then controls the entire transmission system. At this time, when the electric drum 1 rotates, the driving gear 4 also rotates synchronously with the electric drum 1. Since the driven gear 5.1 of the rotary encoder system is meshed with it and drives it to rotate, the rotary encoder 5 counts. Through the rotation speed of the electric drum 1 and the gear ratio of the driving gear 4 to the driven gear 5.1, the length of the steel mesh lifted or lowered by the electric drum 1 when the rotary encoder 5.4 rotates one circle can be calculated.
