The upper part of the brush holder 1 is provided with a puncturing part 11 for puncturing the cleaning agent container 4, the puncturing part 11 corresponds to the connector 41, and the middle part of the brush holder 1 is provided with a through hole 12 communicated with the interior of the cleaning agent container 4.

Referring to fig. 6, a one-way valve 13 and a fixing ring 14 for fixing the one-way valve 13 are disposed at the lower end of the handle 1, and the fixing ring 14 is connected with the handle 1 by a snap-fit connection. The check valve 13 includes a plurality of flow restricting flaps 131, and the check valve 13 is used to restrict the flow of the cleaning agent from the through hole 12 in a non-squeezed state.

The brush head 2 is externally sleeved with a brush part 21, and the brush part 21 is brush, sponge, cleaning ball or woven fabric. The brush head 2 is provided with a drainage hole 22 communicated with the through hole 12. Preferably, the bristle part 21 is composed of a plurality of radially extending bristles 211.

In the use, firstly, the cleaning agent container 4 is fixed in the cavity, the cleaning agent container 4 is communicated with the through hole 12, then the sliding button 32 is pushed to enable the pressing block 31 to extrude the telescopic part 42 of the cleaning agent container 4, the air pressure in the cleaning agent container 4 is increased, then the cleaning agent enters the through hole 12 through the puncture part 11, then the cleaning agent reaches the one-way valve 13 and enables the flow limiting flap 131 to deform and pass through, finally reaches the flow guide hole 22 and flows out, and then cleaning can be carried out. When the slide button 32 is released, the expansion part 42 is reset to indirectly reset the pressing block 31 and the slide button 32.

The one-way nozzle 5 is used to inject air into the cleaning agent container 4 and prevent the cleaning agent from flowing out through the nozzle a. During the resetting process of the telescopic part 42, negative pressure is generated in the cleaning agent container 4, and air enters through the nozzle a of the one-way nozzle 5, so that the suction of the through hole 12 or the drainage hole 22 is prevented.

Referring to fig. 10, a sealing ring 61 is disposed on the outer peripheral surface of the silicone pad 6, and the sealing ring 61 improves the sealing effect between the silicone pad 6 and the inner wall of the cleaning agent container 4. And a second air hole 43 is formed at one end of the cleaning agent container 4 close to the silica gel pad 6. The second vent hole 43 is used to keep the air pressure in the cleaning agent container 4 stable and allow the silica gel pad 6 to move with the cleaning agent.

The cleaning agent container 4 is cylindrical, and the handle 3 is provided with a circular opening 33 corresponding to the cleaning agent container 4.

The brush further comprises a buffer part 7 located between the brush handle 1 and the handle 3, two ends of the buffer part 7 are respectively in threaded connection with the brush handle 1 and the handle 3, a buffer chamber 71 capable of containing a cleaning agent is arranged in the buffer part 7, and the buffer part 7 is provided with an extrusion cap 72 used for extruding the buffer chamber 71.

The end part of the handle 3 is provided with a first one-way flow limiting nozzle 34, the buffer part 7 is provided with a second one-way flow limiting nozzle 73, the first one-way flow limiting nozzle 34 and the second one-way flow limiting nozzle 73 are both provided with nozzles a with gradually reduced openings, the nozzle a of the first one-way flow limiting nozzle 34 faces the buffer cavity 71, and the nozzle a of the second one-way flow limiting nozzle 73 faces the through hole 12 of the brush holder 1. The first one-way flow limiting nozzle 34 and the second one-way flow limiting nozzle 73 are respectively connected and fixed by a fixing ring 14, and the fixing ring 14 is respectively connected with the handle 3 and the buffer part 7 in a buckling manner.

In the using process, the cleaning agent in the cleaning agent container 4 flows to the buffer chamber 71 through the first one-way flow limiting nozzle 34 by continuously pressing the pressing cap 72, then flows to the through hole 12 through the second one-way flow limiting nozzle 73, and finally flows to the drainage hole 22. The user then holds the handle 3 to start washing.
