[0011] Optionally, the upper cover is configured as an elastic upper cover.
[0012] Optionally, the shampoo brush further comprises:
[0013] An elastic member is sleeved on the sealing column, and two ends of the elastic member are respectively in contact with the upper cover and the partition plate.
[0014] Optionally, some of the brush teeth include:
[0015] First brush your teeth;
[0016] Second brush teeth, a plurality of the second brush teeth are arranged at intervals from the first brush teeth, and a plurality of the second brush teeth are all provided with a liquid flow hole communicated with the delay cavity.
[0017] Optionally, a transparent window is further provided on the outer peripheral surface of the brush head body, and the transparent window is used to observe the liquid level of the liquid storage tank.

When washing the hair, the shampooing agent stored in the shampooing brush 10 can be used to directly clean the head, so that the user does not need to temporarily take the shampooing agent from the shampoo bottle when washing the hair, and can avoid scratching the upper scalp with fingers, thereby ensuring convenience and safety when washing the hair.
[0037] Please refer to Figure 2 and Figure 3The shampooing brush 10 comprises a brush head body 11, an upper cover 12 and a sealing column 13. The brush head body 11 is provided with a delay chamber 111, a liquid reservoir 112 and a partition 113. The partition 113 is used to separate the delay chamber 111 from the liquid reservoir 112, that is, the partition 113 is located between the delay chamber 111 and the liquid reservoir 112. The liquid reservoir 112 is used to store shampoo reagents, and the delay chamber 111 is used to temporarily store shampoo reagents. A leakage hole 1131 is opened on the partition 113, and the liquid reservoir 112 and the delay chamber 111 are connected through the leakage hole 1131, that is, the shampoo reagent stored in the liquid reservoir 112 enters the delay chamber 111 through the leakage hole 1131. 1, a liquid outlet 1111 is provided on the cavity wall of the delay cavity 111 away from the partition 113, and the shampoo reagent entering the delay cavity 111 flows out through the liquid outlet 1111 to reach the washing and care position of the user, effectively slowing down the speed of the shampoo reagent reaching the liquid outlet 1111 from the liquid storage tank 112, preventing the shampoo reagent from being excessively squeezed out of the liquid outlet 1111, so that the shampoo reagent can be evenly applied to the hair when the user washes his hair, thereby effectively improving the user's shampooing comfort and efficiency; a plurality of brush teeth 114 are provided on the outer cavity wall of the delay cavity 111, and the brush teeth 114 are used to clean the user's scalp and evenly apply the shampoo reagent.The upper cover 12 is detachably connected to the notch of the liquid storage tank 112, and the upper cover 12 is used to close the liquid storage tank 112.

The ring portion 132, the first liquid outlet ring portion 131 is located in the area of the liquid storage tank 112, that is, the first liquid outlet ring portion 131 is provided on the area where the sealing column 13 is located in the liquid storage tank 112; the second liquid outlet ring portion 132 is located in the area of the delay chamber 111, that is, the second liquid outlet ring portion 132 is provided on the area where the sealing column 13 is located in the delay chamber 111; when the user washes the hair, the upper cover 12 is pressed to make the first liquid outlet ring portion 131 slide into the leakage hole 1131, and the leakage hole 1131 is turned on, and the shampoo reagent flows from the liquid storage tank 112 into the delay chamber 111 through the leakage hole 1131; at the same time, the second liquid outlet ring portion 132 will slide into the liquid outlet hole 1111, connect the liquid outlet hole 1111, and the shampoo reagent will then flow out of the delay chamber 111 through the liquid outlet hole 1111 to reach the washing and care position of the user; that is, when the user presses the upper cover 12, the shampoo reagent in the liquid storage tank 112 will first enter the delay chamber 111 through the leakage hole 1131, and then reach the liquid outlet hole 1111 and flow out after passing through the delay chamber 111, thereby reaching the washing and care position of the user; when the user releases the upper cover 12, the upper cover 12 drives the sealing column 13 to rebound, and the upper cover 12 drives the first liquid outlet ring part 131 to slide out of the leakage hole 1131, sealing the leakage hole 11 31 is closed, and at the same time, the upper cover 12 also drives the second liquid outlet ring part 132 to slide out of the liquid outlet hole 1111, and seals and closes the liquid outlet hole 1111, that is, the sealing column 13 will seal the leakage hole 1131 and the liquid outlet hole 1111 at the same time; at this time, the shampoo reagent in the liquid storage tank 112 will no longer flow into the delay chamber 111, and the shampoo reagent in the delay chamber 111 will no longer flow out through the liquid outlet hole 1111, that is, a part of the shampoo reagent is intercepted in the delay chamber 111; therefore, the amount of shampoo reagent flowing out of the liquid outlet hole 1111 is less than the amount of shampoo reagent flowing out of the leakage hole 1131, thereby avoiding excessive amount of shampoo reagent flowing out of the shampoo brush 10.
[0038] In some embodiments, the shampooing brush 10 includes a brush head body 11, an upper cover 12 and a sealing column 13. The brush head body 11 is provided with a delay chamber 111, a liquid reservoir 112 and a partition 113.
