The elastic lock catch is inserted into the buckle hole and abuts against the elastic unlocking part. The elastic unlocking part drives the elastic lock catch to be separated from the buckle hole to unlock the connection between the end cover and the brush handle. In the technical solution, the elastic unlocking part abutting against the elastic lock catch is arranged on the brush handle. The elastic unlocking part triggers the unlocking mechanism. Compared with the mechanism of unlocking by pressing the elastic lock catch, since the elastic lock catch is formed on the end cover, the user needs to keep pressing the elastic lock catch with one hand and take the end cover with the other hand. It is inconvenient to keep pressing the elastic lock catch, and it is more laborious and time-consuming to unlock. In the technical solution, when the elastic unlocking part is pressed, the elastic unlocking part drives the elastic lock catch to be separated from the buckle hole by elastic deformation, so that the end cover is unlocked with the brush handle.

[0037] More specifically, as shown in Figure 2 and Figure 4 , the accommodating cavity 11 extends along the length direction of the brush handle 1, and the size of the liquid storage bottle 3 is matched with the size of the accommodating cavity 11. The accommodating cavity 11 extends along the length direction of the brush handle 1, so that the accommodating cavity 11 can fully utilize the internal space of the brush handle 1, thereby providing a larger accommodation space for the liquid storage bottle 3. The size of the liquid storage bottle 3 is matched with the size of the accommodating cavity 11, which ensures that the size of the liquid storage bottle 3 is as large as possible, thereby being able to accommodate more cleaning liquid. The close cooperation between the liquid storage bottle 3 and the accommodating cavity 11 reduces the risk of liquid leakage and enhances the durability and reliability of the cleaning brush. The length of the bottle body 31 is greater than or equal to two-thirds of the length of the brush handle 1, which ensures that the liquid storage bottle 3 has sufficient capacity to store cleaning liquid. More cleaning liquid can be stored in the liquid storage bottle 3, reducing the need for frequent cleaning liquid replenishment and improving the continuity of cleaning work. The large-capacity liquid storage bottle 3 makes the cleaning brush suitable for various cleaning scenarios and meets various cleaning needs, which is more practical.

The spray head 32 can move along the length direction of the brush handle 1 to realize telescopic movement through the accommodating cavity 11. When the liquid storage bottle 3 is installed in the accommodating cavity 11, the spray head 32 extends out of the opening 12 along the accommodating cavity 11, the positioning protrusion 321 enters into the limiting groove 14 along the length direction of the brush handle 1, and the positioning protrusion 321 rotates to limit the limiting groove 14 in the circumferential direction, so that the spray head 32 is rotate locked, the spray head 32 has a stable spraying direction, and the spray head 32 can be kept in the set direction during use to prevent the spraying direction from changing due to accidental rotation. When the liquid storage bottle 3 is separated from the accommodating cavity 11, the spray head 32 is retracted into the opening 12 along the accommodating cavity 11, and the positioning protrusion 321 is separated from the limiting groove 14 along the length direction of the brush handle 1, so as not to interfere with the disassembly of the liquid storage bottle 3. The matching structure is simple and reliable. On the other hand, the positions of the positioning protrusion 321 and the limiting groove 14 in the scheme can be interchanged. The positioning protrusion 321 can be arranged at the opening 12, and the limiting groove 14 is correspondingly arranged on the spray head 32.

The rotationally connected structure is simple and reliable, so that the cleaning brush can adapt to different angle and direction cleaning requirements, and the flexibility of operation is improved. The elastic limiting structure is installed in the connecting part 26. The elastic limiting structure is used to rotationally lock the rotating shaft 15. The elastic limiting structure is used to rotationally lock the rotating shaft 15 when the brush head 2 rotates to a specific position. The elastic limiting structure allows the brush head 2 to freely rotate within a certain angle range, and can lock the position after rotation, preventing displacement due to external force, and ensuring the stability of the brush head 2 when the angle needs to be fixed. Especially when the brush head 2 rotates to the parallel and perpendicular positions of the brush handle 1, the stability of the position of the brush head 2 during cleaning is enhanced, preventing the brush head 2 from rotating due to accidental touch or pressure, so that the cleaning work is more efficient.
