Abstract: An plug storage structure of a cleaning robot is presented. A charging structure includes a charging base and a main body of an electronic device. The charging base includes a charging terminal and a projecting portion. The main body has an external housing, charging plugs and an plug storage device. When the main body reaches the charging base, the projecting portion triggers the plug storage device, so that the charging plugs protrude from the external housing, so as to be connected to the charging terminal. When the main body leaves the charging base, the plug storage device automatically receives the charging plugs inside the external housing, so as to keep the plugs of the cleaning robot received inside the external housing during cleaning, thereby preventing the plugs of the cleaning robot from colliding with and damaging adjacent furniture.

Abstract: A transmission assembly and a wheel thereof are presented, and the wheel includes a wheel frame and a tire skin. The wheel frame has a ring-shaped joint surface surrounding the wheel frame, and the joint surface is disposed with at least one slot. The slot has two opposite side walls and at least one stopping wall, and the stopping wall is located between the two side walls. The tire skin is ring-shaped. The tire skin is sleeved on the wheel frame, and attached to the joint surface. The tire skin has at least one protruding rib, and the protruding rib is located in the slot. The stopping wall limits displacement of the protruding rib in a direction of a wheel shaft, and the two side walls limit displacement of the protruding rib in a direction of rotation, thus achieving a good combination effect between the tire skin and the wheel frame.

Abstract: The dust container is disposed in the dust collector, so as to receive dirt drawn by the dust collector. The dust container includes a fastening device. The dust container can be taken out from the dust collector by operating the fastening device in one operation, and then installed back into the dust collector after the dirt is cleared away, thereby completing actions of disassembling, assembling and clearing the dust container quickly and cleanly.
