As shown in FIG. 3, FIG. 4 and FIG. 5, the mop head assembly 4 has a mop head housing 4a on which a rotatable cleaning roller 4b is disposed. Preferably, the mop head housing 4a is internally provided with a motor for driving the cleaning roller 4b, and the motor is connected to the cleaning roller 4b through a transmission mechanism assembly. Preferably, the transmission mechanism assembly comprises a change gear set, a drive belt and a roller connector 4d; the motor 4c, the change gear set, the drive belt and the roller connector 4d are sequentially connected; the roller connector 4d is rotatably disposed on the mop head housing 4a; and the cleaning roller 4b is fitted to the roller connector 4d. Preferably, one end of the roller connector 4d is correspondingly connected to a pulley of the drive belt at one end, the roller connector 4d is fitted at the other end, and the roller connector 4d is mounted on the mop head housing 4a by a bearing.

As shown in FIG. 4 to FIG. 7 the cleaning base assembly 5 has a casing member 5a; a cleaning tank 5aa is formed in an upper surface of the casing member; a decontamination assembly for scrubbing the mop is disposed in the cleaning tank 5aa, and the housing member 5a is provided with a drainage system for discharging sewage. Preferably, a positioning groove 5ab for placing the mop head is disposed in the cleaning tank 5aa. Preferably, the decontamination assembly comprises a squeezing scraper strip 5b, and the squeezing scraper strip 5b is disposed at an edge of the positioning groove 5ab. Preferably, the drainage system comprises a drain valve 5c, an water inlet end of the drain valve 5c is connected into the cleaning tank 5aa, a water outlet end of the drain valve Sc is connected to the outside of the casing member 5a, and a button 5d for starting the drain valve 5c is disposed on the casing member 5a.

The specific structural form of the cleaning base assembly 5 is given in this embodiment, wherein the casing member 5a is the body of the cleaning base assembly 5, and the cleaning tank 5aa is used for containing water for cleaning the mop. The decontamination assembly is used to help the roller on the mop to discharge the adsorbed sewage. In the specific implementation, in order to naturally discharge sewage out of the cleaning tank 5aa, the bottom surface of the cleaning tank 5aa is set as an inclined surface to facilitate the natural flowing and drainage of the sewage. The casing member 5a is integrally formed; therefore, as shown in the figure, the cleaning tank 5aa is formed by recessing downward the whole upper plate surface of the casing member 5a, and correspondingly the positioning groove 5ab is also formed by entirely recessing the casing member 5a. Through the bending of the main plate surface of the casing member 5a, a cavity is naturally formed underneath it for arranging the relevant components of the drainage system.

Preferably, the drainage system comprises a drain valve 5c, an water inlet end of the drain valve 5c is connected into the cleaning tank 5aa, and a water outlet end of the drain valve 5c is connected to the outside of the casing member 5a. Preferably, a button 5d for starting the drain valve 5c is disposed on the casing member 5a. Preferably, a switch of the drain valve Sc is provided with a first rack Se for starting the switch; the valve body of the drain valve 5c is further provided with a duplex gear 5f and a second rack 5g; the duplex gear 5f has a gear portion with a larger outer diameter to mesh with the first rack Se, the duplex gear has a gear portion with a smaller outer diameter to mesh with the second rack 5g, and the second rack 5g is connected to the button 5d.

In the above embodiments, as a preferred solution, the button 5d is pressed down to drive the second rack 5g, the second rack 5g then drives the duplex gear 5f to rotate, the duplex gear 5f drives the first rack Se to move, and the switch of the drain valve 5c is opened by the movement of the first rack Se. Based on this, the drain valve 5c may be a spring one-way valve, and the returning of the action of opening the valve is realized by using a spring of the spring one-way valve, that is, when the pressure on the button 5d is removed, under the action of the spring of the spring one-way valve, the valve flap in the valve returns back to drive the switch of the valve to return back, thereby causing the first rack Se, the duplex gear 5f and the second rack 5g to move in the opposite direction, and further realizing the reverse return of the above-mentioned related components. The drain valve 5c is connected to the outside of the casing member 5a through the drain pipe 5h, which is advantageous for the drainage effect.
