[0073] The inlet end of the hot water outlet pipe 39 is connected to the hot water outlet end of the integrated water circuit board 32, and the outlet end of the hot water outlet pipe 39 is connected to the inlet end of the faucet 12.

[0074] In addition, hot and cold water are delivered by the water pressure of the tap water pipe, while the detergent is delivered by an electromagnetic pump. In this embodiment, the electromagnetic pump can be set at the detergent inlet pipe 33 or other suitable location. This is a conventional structure and is not shown in the figure.

[0075] The working principle of this embodiment is as follows:

[0076] (1) When cleaning, first open the box cover 113, then hold the handle 212 to take the entire cleaning brush 2 out of the storage box 112. Next, adjust the angle between the handle 212 and the housing 211 as needed, and finally start the cleaning brush 2. The drive mechanism 23 drives the brush head 22 to rotate.

[0077] When the surface is dirty and requires cleaning agent, the cleaning agent in the cleaning agent bottle 31 enters the integrated water circuit board 32 through the cleaning agent inlet pipe 33, and then is delivered to the spray nozzle 2213 of the brush head 22 through the cleaning agent outlet pipe 36 and the water gun 2112 to be sprayed out and applied to the surface to be cleaned.

[0078] When it is necessary to clean the dirt with water, cold or hot water enters the integrated water circuit board 32 through the cold water inlet pipe 34 or the hot water inlet pipe 35, and then is delivered to the spray hole 2213 of the brush head 22 through the cold and hot water pipes 37 and the water gun 2112 to clean the surface to be cleaned.

[0079] When cleaning curved surfaces (such as the outer wall of a pot), the outer brush plate 222 is flush with the inner brush plate 221. Since the height of the outer brush strip 2221 is greater than the height of the inner brush strip 2211, the surface of the brush head 22 forms a concave structure.

[0080] When cleaning the inner curved surface (such as the inner wall of a pot), the outer brush plate 222 deforms toward the shell 211 under the action of the inner curved surface, so that the outer brush strip 2221 can freely fit according to the state of the curved surface;

[0081] (2) After cleaning, first adjust the angle between the handle 212 and the housing 211 to 90°, then hold the handle 212 and put the entire cleaning brush 2 into the storage box 112, then close the box cover 113, and finally start the cleaning brush 2. The drive mechanism 23 drives the brush head 22 to rotate, and at the same time the cleaning medium supply device 3 supplies cleaning water to the cleaning brush 2 and sprays it out from the spray hole 2213 to rinse the brush head 22. The wastewater is discharged through the drain port 1122, thereby realizing the self-cleaning of the brush head 22.
