Unless otherwise specified, "plurality" means two or more.

[0023] It should also be understood that the terms used in the utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0024] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0025] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a bristle, and a plurality of powder hanging grooves are arranged on the surface of the bristle. Specifically, the powder hanging grooves on the surface of the bristle can conveniently and effectively pick up various loose powder textures, thereby improving the powder absorption and powder hanging properties of the bristle.

[0026] Powder pickup experiment: Three brush heads with different materials, the same number of hairs or fibers, and the same head shape were made of ordinary fibers, wool, and the bristles of this embodiment, and were installed on the same base or brush handle.

[0027] Experimental method: Under the same force, use the three brush heads mentioned above to pick up the same powder once, and detect the powder area under a high-power microscope; the above operation is repeated 10 times, and the average value is taken to obtain the experimental data shown in the following table.

[0028] Brush head material Carbon fiber wool This embodiment of the bristles Pickup performance 100％ 138％ 160％

[0029] During the specific implementation of this embodiment, the powder hanging groove is an elliptical groove. By corroding and oxidizing the bristles, tiny elliptical grooves are formed on the surface of the bristles to improve the powder absorption and powder hanging properties of the bristles. The elliptical shape is more conducive to uniform powder brushing and powder release.

[0030] In the specific implementation of this embodiment, the length of the powder hanging groove is 90um, and other values ​​in the range of 70-110um can also be selected in other embodiments; the width of the powder hanging groove is 18um, and other values ​​in the range of 16-20um can also be selected in other embodiments.

[0031] In the specific implementation of this embodiment, the depth of the powder hanging groove is 7 um. In other embodiments, other values ​​in the range of 6-8 um can also be selected.

[0032] During the specific implementation of this embodiment, the tail of the bristles is in a spiral structure or a wavy structure, and the multiple curved parts on the bristles can increase the powder hanging performance, which is conducive to multiple and uniform powder release and is softer and more comfortable to touch on the face; when the entire bundle of bristles is made into a brush head, the gap between the bristles is increased, and the powder is released faster and more evenly when applying makeup.

[0033] During the specific implementation of this embodiment, the roots of the bristles are cylindrical in structure, which can increase the hardness and support of the bristles.

[0034] In the specific implementation process of this embodiment, the material of the bristles is PBT, and in other embodiments, PET or other synthetic fibers can also be selected. Specifically, nanomaterials can be added to the bristle material to change the molecular structure of the bristles and improve the fiber elasticity.

[0035] Based on the same inventive concept as the above-mentioned bristles, the embodiment of the present application also provides a brush head, which includes a plurality of bristles as described in any one of the above items. Specifically, the brush head of the embodiment of the present application has good powder pickup performance, and it is easier to release powder gently, evenly and rhythmically during the makeup process, which can better and quickly create a uniform makeup effect and present a delicate texture.

[0036] Based on the same inventive concept as the bristles, the embodiment of the present application also provides a makeup brush, including a brush handle and the brush head as described above, the brush head being mounted on the brush handle. Specifically, the makeup brush of the embodiment of the present application has good powder pickup performance, and is more likely to release powder gently, evenly, and rhythmically during the makeup process, which can better and quickly create a uniform makeup effect and present a delicate texture.

[0037] Regarding the embodiments of the present utility model, it should also be noted that, in the absence of conflict, the embodiments of the present utility model and the features therein can be combined with each other to obtain new embodiments.

[0038] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. The protection scope of the utility model shall be based on the protection scope of the claims. Although the utility model has been disclosed as a preferred embodiment, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modify the technical content disclosed above to an equivalent embodiment with equivalent changes without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of the technical solution of the utility model.
