Mechanical friction feedback center air-conditioning tube clearing mechanism

The utility model discloses a mechanical friction feedback central air-conditioning pipeline cleaning mechanism. A driving gear is driven by power output by a motor, and two sets of double-sliding chute swinging mechanisms which are the same in structure and are symmetrically arranged on a cleaning base are driven to rotate by the driving gear; brushes are arranged on the driven belt wheels of the double-sliding chute mechanisms; two pairs of sliding chutes and holes arranged on the cleaning base and a brush clamp are connected by a shaft to form a double-sliding chute swinging mechanism, and the brush can tightly cling to the wall surface for cleaning by friction force feedback, thus the wall surface can be effectively cleaned when walking errors appears and the section of a pipeline is changed, and the positive pressure of the brush on the wall surface is large when the friction force of the wall surface is large. Therefore, the cleaning efficiency is higher even when the wall surface is dirtier. A fastenin
