The controlling device 3 is configured to control the cleaning solution in the cavity 2 to be sprayed toward the to-be-cleaned surface, so as to help the plurality of bristles remove stains from the to-be-cleaned surface.

Specifically, the cavity 2 includes a cavity body 21, a dispensing device 22 and a first nozzle 25. A mouth (not shown in the figures) of the cavity body 21 is provided with a cap 24. The cap 24 is threadedly connected to the mouth. A first through-hole (not shown in the figures) is arranged at a center portion of the cap 24. The first nozzle 25 is configured to pass through the first through-hole. The dispensing device 22 is threadedly fixed to an upper end portion of the first nozzle 25. A center portion of the dispensing device 22 is provided with a second through-hole (not shown in the figures). A first water-stopping ball 23 is provided in the second through-hole, and the first water-stopping ball 23 is configured to move along the second through-hole to block both ends of the second through-hole. An upper portion of the dispensing device 22 is threadedly provided with a second nozzle 30 for liquid suction, in which a water flow channel (not shown in the figures) is provided. A diameter of the water flow channel is smaller than that of the first water-stopping ball 23. A lower end portion of the second through-hole is tapered to allow the first water-stopping ball 23 to plug the lower end portion of the second through-hole. An upper end portion of the second through-hole is configured to fit the second nozzle 30 to allow the first water-stopping ball 23 to plug the upper end portion of the second through-hole. The upper end of the first nozzle 25 is vertically provided with a first counterbore hole (not shown in the figures). A lower end portion of the first nozzle 25 is vertically provided with a second counterbore hole (not shown in the figures). The first counterbore hole is communicated with the second counterbore hole. A stopper 28 is provided in the first counterbore hole, and is configured to move vertically to block communication between the first counterbore hole and the second counterbore hole. A sealing ring 26 is provided at the upper end portion of the first nozzle 25. A spring 27 is provided between the sealing ring 26 and the stopper 28. The dispensing device 22 is provided with a first water outlet 221. The first water outlet 221 is communicated with the first counterbore hole.

The groove is configured to fit the cap 24. An ejector block 29 is provided at a bottom center of the groove. The ejector block 29 is provided with a second water outlet 291. In response to a case that the cap 24 is inserted into the groove, the ejector block 29 is configured to be inserted into the second counterbore hole and squeeze the stopper 28 upward, so as to achieve the communication among the first counterbore hole, the second counterbore hole and the second water outlet 291. When the cap 24 is pulled out from the groove, the ejector block 29 does not squeeze the stopper 28 upwardly, and the area between the first counterbore hole and the second counterbore hole is blocked by the stopper 28.

The controlling device 3 includes a main body (not shown in the figures). A main body of the controlling device is provided with a negative-pressure chamber 33. The negative-pressure chamber 33 is provided with a button 31. The button 31 is configured to control pressure change of the negative-pressure chamber 33. A first reset spring 32 is provided between a bottom of the negative-pressure chamber 33 and the button 31, and is configured to reset the button 31 when the button 31 is released. The negative-pressure chamber 33 is communicated with a water inlet channel and a water outlet channel. The water inlet channel is communicated with a water inlet pipe 4. The water inlet pipe 4 is communicated with the second water outlet 291. The water outlet channel is communicated with a water outlet pipe 5. The water outlet pipe 5 is configured to carry the cleaning solution inside the cavity 2 to the to-be-cleaned surface. A second water-stopping ball (not shown in the figures) is provided at an end of the water inlet channel away from the negative-pressure chamber. A second reset spring is provided between an end of the water inlet channel near the negative-pressure chamber 33 and the second water-stopping ball. When a pressure inside the negative-pressure chamber 33 increases to overcome a pressure applied by the second reset spring, the second water-stopping ball is configured to plug the end of the water inlet channel away from the negative-pressure chamber 33, and at this time, no water can enter the water inlet channel. When the pressure inside the negative-pressure chamber 33 decreases, the second water-stopping ball is configured to move away from the end of the water inlet channel away from the negative-pressure chamber 33 under the action of the second reset spring, and at this time, water is allowed to enter the water inlet channel. A third water-stopping ball (not shown in the figures) is provided at an end of the water outlet channel near the negative-pressure chamber 33. A third reset spring is provided between an end of the water outlet channel away from the negative pressure chamber 33 and the third water-stopping ball. When the pressure in the negative-pressure chamber 33 increases to overcome a pressure applied by the third reset spring, the third water-stopping ball is configured to move away from the end of the water outlet channel near the negative-pressure chamber 33, and at this time, the water outlet channel is configured to discharge water. When the pressure in the negative-pressure chamber 33 decreases, the third water-stopping ball is configured to plug the end of the water outlet channel near the negative-pressure chamber 33 under the action of the third reset spring, and at this time, no water can flow out of the water outlet channel.

A battery 14 is provided in the main body of the controlling device 3, and is configured to supply power to the motor 11.

In this embodiment, the sealing ring 26 and the stopper 28 are made of a rubber material, respectively.

During the operation, the cap 24 is inserted into the groove, and the ejector block 29 is inserted into the second counterbore hole to squeeze the stopper 28 upward, so as to achieve the communication among the first counterbore hole, the second counterbore hole and the second water outlet 291. The motor 11 is started to drive the brush disk 13 to rotate, so as to drive the bristles thereon to clean a to-be-cleaned surface. As needed, the button 31 is pressed to spray the cleaning solution in the cavity 2. In a case that the cavity 2 is vertical, the lower end portion of the second through-hole is plugged by the first water-stopping ball 23. When the button 31 is pressed and the pressure in the negative-pressure chamber 33 increases to overcome a pressure applied by the third reset spring, the third water-stopping ball will move away from the end of the water inlet channel near the negative-pressure chamber 33. At this time, liquid can be output through the water outlet channel, and the cleaning solution inside the cavity 2 can be carried to the to-be-cleaned surface through the water outlet pipe 5 is configured to carry to. At the same time, the pressure inside the negative-pressure chamber 33 increases to overcome a pressure applied by the second reset spring, such that the second water-stopping ball can plug the end of the water inlet channel away from the negative-pressure chamber 33. At this time, no water can enter the water inlet channel. After the button 31 is released, the button 31 is reset under the action of the first reset spring 32. At this time, the pressure inside the negative-pressure chamber 33 decreases, and the second water-stopping ball will move away from the end of the water inlet channel away from the negative-pressure chamber 33 under the action of the second reset spring, such that water can enter the water inlet channel. Meanwhile, the sealing ring 26 is deformed under the action of negative pressure to achieve the communication between the first water outlet 221 and the first counterbore hole. In this way, the cleaning solution in the cavity 2 can pass through the first water outlet 221, the first counterbore hole, the second counterbore hole and the second water outlet 291 in turn into the water inlet pipe 4 and then into the negative-pressure chamber 33. Simultaneously, the third water-stopping ball can plug the end of the water outlet channel near the negative-pressure chamber 33 under the action of the third reset spring, and no water can come out of the water outlet channel. The above operations are repeated to complete the cleaning of the to-be-cleaned surface. In a case that the cavity 2 is inverted, the first water-stopping ball 23 seals the upper end portion of the second through-hole. When the button 31 is pressed and the pressure in the negative-pressure chamber 33 increases to overcome a pressure applied by the third reset spring, the third water-stopping ball will move away from the end of the water inlet channel near the negative-pressure chamber 33, and at this time, liquid can be output through the water outlet channel, and the cleaning solution inside the cavity 2 can be carried to the to-be-cleaned surface through the water outlet pipe 5. At the same time, when the pressure inside the negative-pressure chamber 33 can overcome a pressure applied by the second reset spring, the second water-stopping ball plugs the end of the water inlet channel away from the negative-pressure chamber 33, such that no water can enter the water inlet channel. After the button 31 is released, the button 31 is reset under the action of the first reset spring 32. At this time, the pressure inside the negative-pressure chamber 33 decreases, and the second water-stopping ball will move away from the end of the water inlet channel away from the negative-pressure chamber 33 under the action of the second reset spring, and liquid can enter the water inlet channel. At this time, the first water-stopping ball 23 will float upwardly under the action of the negative pressure to achieve the communication between the second through-hole and the first counterbore hole. The cleaning solution in the cavity 2 can pass through the second nozzle 30, the second through-hole, the first counterbore hole, the second counterbore hole and the second water outlet 291 in turn into the water inlet pipe 4 and then into the negative-pressure chamber 33. Simultaneously, the third water-stopping ball can plug the end of the water outlet channel near the negative-pressure chamber 33 under the action of the third reset spring, and no water can come out of the water outlet channel. These operations are repeated to complete the cleaning of the to-be-cleaned surface.
