Rotating brush

Abstract

A rotating brush includes a main body, a cavity for storing a cleaning solution, and a controlling device. The cavity and the controlling device are arranged in the main body. The main body is provided with a motor, whose output shaft is provided with a brush disk. A lower surface of the brush disk is uniformly provided with bristles. The motor can drive the brush disk to operate to drive the bristles to clean the to-be-cleaned surface. The controlling device can control the cleaning solution in the cavity to be sprayed toward the to-be-cleaned surface to help the bristles clean the stubborn stains.

What is claimed is: 
     
         1 . A rotating brush, comprising:

         2 . The rotating brush of  claim 1 , wherein the cavity comprises a cavity body, a dispensing device and a first nozzle;
 a mouth of the cavity body is provided with a cap; the cap is threadedly connected to the mouth; and a first through-hole is arranged at a center portion of the cap;   the first nozzle is configured to pass through the first through-hole; and the dispensing device is threadedly fixed to an upper end portion of the first nozzle;   a center portion of the dispensing device is provided with a second through-hole; a water-stopping ball is provided in the second through-hole; the water-stopping ball is configured to move along the second through-hole to block both ends of the second through-hole;   the upper end portion of the first nozzle is vertically provided with a first counterbore hole; a lower end portion of the first nozzle is vertically provided with a second counterbore hole; and the first counterbore hole is communicated with the second counterbore hole; a stopper is provided in the first counterbore hole; the stopper is configured to move vertically to block communication between the first counterbore hole and the second counterbore hole;   the upper end portion of the first nozzle is provided with a sealing ring; the dispensing device is provided with a first water outlet; the first water outlet is communicated with the first counterbore hole; and the sealing ring is configured to seal the first water outlet; and   a top of the rotating brush body is provided with a groove; the groove is configured to fit the cap; an ejector block is provided at a bottom center of the groove; the ejector block is provided with a second water outlet; and in response to a case that the cap is inserted into the groove, the ejector block is configured to be inserted into the second counterbore hole and squeeze the stopper upward, so as to achieve communication among the first counterbore hole, the second counterbore hole and the second water outlet.   
     
     
         3 . The rotating brush of  claim 2 , wherein an upper portion of the dispensing device is threadedly provided with a second nozzle for liquid suction; and a water flow channel is provided inside the second nozzle. 
     
     
         4 . The rotating brush of  claim 3 , wherein a lower end portion of the second through-hole is tapered to allow the water-stopping ball to plug the lower end portion of the second through-hole; a diameter of the water flow channel is smaller than that of the water-stopping ball; an upper end portion of the second through-hole is configured to fit the second nozzle to allow the water-stopping ball to plug the upper end portion of the second through-hole. 
     
     
         5 . The rotating brush of  claim 2 , wherein a spring is provided between the sealing ring and the stopper. 
     
     
         6 . The rotating brush of  claim 1 , wherein a main body of the controlling device is provided with a negative-pressure chamber; the negative-pressure chamber is provided with a button; and the button is configured to control pressure change of the negative-pressure chamber;
 a first reset spring is provided between a bottom of the negative-pressure chamber and the button; and the first reset spring is configured to reset the button in response to a case that the button is released;   the negative-pressure chamber is communicated with a water inlet channel and a water outlet channel; the water inlet channel is communicated with a water inlet pipe; the water inlet pipe is communicated with the second water outlet; and the water outlet channel is communicated with a water outlet pipe;   the water outlet pipe is configured to carry the cleaning solution inside the cavity to the to-be-cleaned surface;   a first water-stopping ball 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 and the first water-stopping ball;   in response to a case that a pressure inside the negative-pressure chamber increases to overcome a pressure applied by the second reset spring, the first water-stopping ball is configured to plug the end of the water inlet channel away from the negative-pressure chamber; and in response to a case that the pressure inside the negative-pressure chamber decreases, the first water-stopping ball is configured to move away from the end of the water inlet channel away from the negative-pressure chamber under the action of the second reset spring;   a second water-stopping ball is provided at an end of the water outlet channel near the negative-pressure chamber;   a third reset spring is provided between an end of the water outlet channel away from the negative-pressure chamber and the second water-stopping ball; and   in response to a case that the pressure in the negative-pressure chamber increases to overcome a pressure applied by the third reset spring, the second water-stopping ball is configured to move away from the end of the water outlet channel near the negative-pressure chamber; and in response to a case that the pressure in the negative-pressure chamber decreases, the second water-stopping ball is configured to plug the end of the water outlet channel near the negative-pressure chamber under the action of the third reset spring.   
     
     
         7 . The rotating brush of  claim 6 , wherein a battery is provided in the main body of the controlling device; the battery is configured to supply power to the motor.
