[0032] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0033] like Figures 1 to 6 As shown, the embodiment of the utility model provides a cosmetic brush with quickly replaceable bristles, including a brush handle cover 10, a rotary joint 20, a bristle body 30, a locking limit column 40, a spring 50 and an unlocking slider 60;

[0034] The bristle body 30 is arranged on the rotary joint 20, and the bristle body 30 is used to apply cosmetic materials; the bristle body 30 is the part of the makeup brush that actually contacts the cosmetics and applies them to the skin. Bristle bodies 30 of different types and shapes can be suitable for applying different types of cosmetics, such as foundation, eye shadow, blush, etc.

[0035] A positioning column 101 is provided on the top of the brush handle cover 10, and the positioning column 101 is connected to the inner wall of the brush handle cover 10 through a connecting rib 102. A positioning sleeve 201 is provided at the bottom of the rotary joint 20 for the positioning column 101 to be inserted and connected; the positioning sleeve 201 can be inserted on the positioning column 101, so that the rotary joint 20 and the brush handle cover 10 can be accurately positioned during installation.

[0036] like Figures 2 to 4As shown, the top inner wall of the brush handle cover 10 is provided with two symmetrically arranged blocks 103, the outer wall of the positioning sleeve 201 is provided with a slide groove 202, and both sides of the positioning sleeve 201 are provided with slots 203, one end of the slide groove 202 extends into the slot 203, and the block 103 is used to slide into or out of the slot 203 to the slide groove 202 as the rotary joint 20 rotates; when the rotary joint 20 is installed, the position of the slot 203 can be aligned with the block 103, and the positioning sleeve 201 is inserted into the positioning column 101, and then the rotary joint 20 is rotated so that the block 103 can slide into the slide groove 202, thereby realizing the locking of the rotary joint 20 in the vertical direction and preventing the rotary joint 20 from loosening up and down.

[0037] like Figures 3 to 6 As shown, the brush handle cover 10 has an accommodating chamber inside, the locking limit column 40 is arranged in the accommodating chamber, the top of the locking limit column 40 is provided with a limit block 401, the locking limit column 40 is provided with a retaining ring 402, the spring 50 is sleeved on the locking limit column 40 below the retaining ring 402, and the spring 50 is used to apply an upward elastic force to the locking limit column 40 so that the limit block 401 abuts against the groove 203 to achieve rotation locking of the rotary joint 20, thereby preventing the rotary joint 20 from accidentally rotating and slipping off the brush handle cover 10.

[0038] like Figure 5 As shown, the brush handle cover 10 is provided with an unlocking groove 100, the unlocking slider 60 is arranged in the unlocking groove 100, and a pressure block 601 is arranged on the back of the unlocking slider 60, the pressure block 601 abuts against the end of the retaining ring 402 away from the spring 50, and the unlocking slider 60 is used to drive the limit block 401 to withdraw from the slot 203 when subjected to a downward pulling force, so as to release the rotation lock of the rotary joint 20. When the bristle body 30 needs to be replaced, the elastic force of the spring 50 can be overcome by pulling down and sliding the unlocking slider 60, so as to cause the locking limit column 40 to move downward, so that the limit block 401 withdraws from the slot 203. When the limit block 401 withdraws from the slot 203, the rotary joint 20 is no longer restricted by the rotation lock. At this time, the user can slide the block 103 out of the slide slot 202 by rotating the rotary joint 20, thereby realizing the disassembly and separation between the rotary joint 20 and the brush handle cover 10.
