[0083] The mop has the following beneficial effects:

[0084] 1, the water outlet is formed in the side of the protective cover 22 close to the cleaning area 10, when the button 3 is located at the first position, the user can directly observe the conductive pin 200 in the pin area 210 through the water outlet or manually push the button 3 to the second position to observe the conductive pin 200 in the pin area 210, the user can directly observe the pin state to replace the pin in time, avoid the potential danger caused by the aging and oxidation of the pin, and when the button 3 is located at the first position or the second position, the accumulated water in the pin area 210 can flow into the cleaning area 10 from the water outlet, so that the pin of the charger is not easy to be oxidized, and the service life is prolonged.

[0085] 2. By tilting the upper end face 211 of the support base 21 downward toward the cleaning area 10, the water in the needle insertion area 210 flows to the cleaning area 10 by gravity without human intervention.

[0086] 3. By providing a boss 23 between the conductive pin 200 and the support base 21, and the upper surface 230 of the boss 23 being higher than the upper end surface 211 of the support base 21, the water in the cleaning area 10 is less likely to touch the conductive pin 200.

[0087] 4. By opening a guide groove 231 on the upper surface 230 of the boss 23, preferably with the bottom of the guide groove 231 inclined downward toward the cleaning area 10, it is easy for the water in the pin insertion area 210 to be discharged into the cleaning area 10 through the guide groove 231, and to avoid the boss 23 from obstructing the flow of water in the pin insertion area 210.

[0088] 5. By setting a sealing ring between the boss 23 and the support base 21, water accumulated in the pin area 210 is prevented from flowing into the support base 21, thus avoiding short circuit of the conductive parts 20 in the support base 21 caused by water accumulation.

[0089] 6. A non-locking switch 24 is installed between the conductive component 20 and the charging base circuit board 25. Under the control of button 3, the non-locking switch 24 controls the connection and disconnection between the conductive component 20 and the charging base circuit board 25. During the placement of the cleaning device on the charging base, the cleaning device body and button 3 are triggered to move. During the movement of button 3, the non-locking switch 24 is closed, thus connecting the charging circuit. After the cleaning device is removed from the charging base, button 3 is reset by spring 12, causing the non-locking switch 24 to open, thereby disconnecting the charging circuit. This ensures that the conductive component 20 in the charging base is only energized when connected to the mop, preventing oxidation of the metal pins in the conductive component 20.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
