[0030] Reference Figures 1 to 5 As shown, a curved brush is provided, comprising:

[0031] The brush handle 1 has a connecting groove 11 at its bottom end and a positioning protrusion 12 on one side of the connecting groove 11.

[0032] The brush head includes a housing 2 and a connecting plate. The housing 2 is detachably connected to the bottom end of the brush handle 1. The end of the housing 2 near the brush handle 1 is provided with a protrusion 21 that cooperates with the connecting groove 11. One side of the protrusion 21 is provided with a positioning groove 22 that cooperates with the positioning protrusion 12. The connecting plate is fixedly installed at the end of the housing 2 away from the brush handle 1. The connecting plate is provided with several bristles.

[0033] In this embodiment, the brush head is slidably inserted into the connecting groove 11 on the brush handle 1 by aligning the protrusion 21 on the housing 2 with the positioning groove 22 on the housing 2 until it is fully engaged with the positioning protrusion 12 on the brush handle 1. At this time, the brush head is fixedly connected to the brush handle 1. If the brush head needs to be removed, the housing 2 needs to be pushed outward to disengage the positioning protrusion 12 from the positioning groove 22. The protrusion 21 slides out along the length of the connecting groove 11, and the removal is completed. After removal, other brush heads can be replaced, which is suitable for various usage scenarios and saves costs.

[0034] Preferably, one side of the positioning protrusion 12 is provided with a slope to facilitate the sliding engagement of the positioning groove 22 on the housing 2.

[0035] In one embodiment of this utility model, the brush handle 1 is inclined and has a hollow structure inside. The inclined structure of the brush handle 1 relative to the shell 2 makes it easier for the user to grip and use, and makes gripping more comfortable. The hollow structure inside the brush handle 1 can effectively reduce the weight of the brush itself, making it easier to grip and work.

[0036] In one embodiment of the present invention, the brush handle 1 includes a gripping part 13 and a connecting part 14. A stop part 141 is provided on the connecting part 14. The stop part 141 is provided at one end of the connecting part 14. The stop part 141 is used to restrict the shell 2 from continuing to slide, and at the same time plays a guiding role, preventing the shell 2 from being inserted from one side of the stop part 141, and only allowing it to enter from the other side.

[0037] Furthermore, the end of the gripping part 13 away from the connecting part 14 is provided with a hanging hole 131, which is elliptical in shape, so that the curved brush can be hung on the wall.

[0038] Furthermore, the end of the housing 2 near the brush handle 1 is provided with a recess 23 that cooperates with the stop part 141. The recess 23 is used to guide the user to slide the housing 2 into the brush handle 1 from the position of the recess 23 until the positioning protrusion 12 and the positioning groove 22 cooperate and engage, and the recess 23 and the stop part 141 fit together.

[0039] In one embodiment of this utility model, the brush handle 1 is provided with a reinforcing rib 15 inside to increase the strength of the brush handle 1 and prevent it from deforming.

[0040] In one embodiment of this utility model, the thickness of the top end of the brush handle 1 is less than the thickness of the bottom end of the brush handle 1. The thickness of the top end of the brush handle 1 is just right for the user's grip comfort, thereby improving the user's experience.

[0041] In one embodiment of this utility model, the outer surface of the housing 2 has a convex surface 24 protruding outward, and a size mark 25 is provided in the middle of the convex surface 24. When disassembling and replacing the housing 2, it is convenient for the user to see the size of the housing to be replaced, so as to achieve quick and accurate installation.

[0042] In one embodiment of this utility model, the interior of the shell 2 is provided with several annular reinforcing ribs 26 to strengthen the shell 2 and prevent it from deforming.

[0043] In one embodiment of this utility model, magnets are provided at the top of the housing 2 and the bottom of the brush handle 1. The top of the housing 2 and the bottom of the brush handle 1 are magnetically connected. The magnetic force of the two magnets needs to be released by human force, which is sufficient to make the top of the housing 2 and the bottom of the brush handle 1 magnetically attracted together, further fixing the connection between the housing 2 and the brush handle 1.

[0044] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
