Abstract
An automatic cleaning apparatus includes: a chassis; a front housing arranged at a front end of the chassis; and a sensing device capable sensing movement of the front housing and sending a signal to a control mainboard of the automatic cleaning apparatus when the front housing touches an obstacle and moves relative to the chassis. The sensing device includes a dust blocking member and a rocker arm that triggers the sensing device to send the signal. The rocker arm has a first end rotatably arranged inside the sensing device, and a second end passing through the dust blocking member and extending out of the sensing device. A front housing reset device is arranged on the chassis and capable of biasing the front housing toward an initial position of the front housing.
