The mounting portions 221 of the mop holder 202 are formed in a boss shape and provided on both sides of the mop holder 202, and when the mop holder 202 is mounted, the mounting portions 221 of the mop holder 202 are engaged with the concave portions 231 of the water outlet upper cover 213. Therefore, the cleaning assembly 200 provided in the embodiment of the present application is more compact in structure by the above arrangement, and the mounting portion 221 of the mop support 202 does not affect the shape of the side wall 111 and the bottom surface 112 of the box body 101, and does not block the dust or garbage in the dust storage cavity 12, thereby preventing the dust or garbage from accumulating in the dust storage cavity 12 of the box body 101, and solving the problem of dust accumulation in the dust storage cavity 12 of the box body 101.

Referring to fig. 5, in some embodiments of the present application, a water outlet channel is provided on the lower water outlet cover 214, the water outlet channel is formed by a liquid inlet 215, a hose 216, a flow channel 217 and a liquid outlet 218, the liquid outlet 218 is communicated with the liquid inlet 215 through the flow channel 217 and the hose 216, the flow channel 217 is formed by enclosing the upper water outlet cover 213 and the lower water outlet cover 214, the flow channel 217 is provided between mounting parts 221 of the mop support 202, and the liquid outlet 217 is provided at the end of the flow channel 217.

When it is required to supply the cleaning solution to the mop below the mop support 202, the air pump of the cleaning robot is operated to increase the pressure in the liquid storage tank 200, wherein the stored cleaning solution flows in from the liquid inlet 215, flows into the flow channel 217 through the hose 216, and finally flows onto the mop through the liquid outlet 218, as shown in fig. 5, the number of the liquid outlets 218 is two, and the liquid outlets are respectively positioned at two ends of the flow channel 217, so that the cleaning solution flows out from the hose 216, flows out from the middle to the liquid outlets 218 at two sides through the flow channel 217, and thus the cleaning solution can be uniformly split, and the cleaning solution can be ensured to uniformly flow onto the mop, thereby further improving the cleaning effect. In some embodiments of the application, the width of the flow channel 217 is twice the aperture of the outlet 218, so that the cleaning liquid can be further evenly split, ensuring that the cleaning liquid can flow evenly onto the mop. As shown in fig. 5, the hose 216 is bent in a tubular shape, and the cleaning liquid is pressed into the hose 216 only when the air pump increases the pressure in the tank 200, and the cleaning liquid is difficult to flow into the hose 216 when the tank 200 is left standing, thereby preventing the tank standing leakage problem.

The embodiment of the present application further provides a cleaning robot, which includes a robot body and a cleaning assembly 200, and the specific structure of the cleaning assembly refers to the above embodiment. Wherein, clean subassembly and robot body can dismantle the connection.

Specifically, the cleaning robot provided by the embodiment of the application is a robot capable of cleaning an object, the cleaning robot comprises a robot body and a cleaning assembly 200, and the cleaning assembly 200 is mounted on the robot body.
