Lifting-and-lowering assembly and cleaning device

A cleaning device, comprising:

• a device body;
• and
• a lifting-and-lowering assembly,
• wherein the lifting-and-lowering assembly comprises:
• a mounting seat;
• a distance-sensing module liftably and lowerably arranged at the mounting seat, wherein the distance-sensing module comprises a sensing body and a movable body movably connected to the sensing body, the movable body has a first trigger structure, and the sensing body has a protective switch located in a movement path of the first trigger structure;
• and
• a drive control module assembled with the mounting seat, comprising a control main board, a drive motor and an adapting member in transmission connection with the drive motor, wherein the sensing body is arranged on the adapting member, and the drive motor and the protective switch are each electrically connected to the control main board to drive the distance-sensing module to lift and lower,
• wherein the device body has a receiving cavity, and the lifting-and-lowering assembly is assembled in the receiving cavity;
• and the distance-sensing module has a first operating state where the distance-sensing module is received in the receiving cavity and a second operating state where the distance-sensing module protrudes above a top of the device body in a lifting-and-lowering direction.
