Description

Technical Field

[0001] The utility model relates to the technical field of cosmetics, and in particular to a telescopic brush head applied to a cosmetic bottle. Background Art

[0002] A cosmetic bottle typically consists of a bottle body and a lid with a brush attached. The brush consists of a stem and a brush head secured within the lid. To use, unscrew the lid and lift the brush out of the bottle, leaving the brush head coated with the product. Examples include nail polish and lip gloss bottles.

[0003] In current use, the main problem is that the lower end of the brush head is at the bottom of the beauty bottle only when the lid is screwed on the beauty bottle. When the brush head is rotated to open, there is a certain height difference between the brush head and the bottom of the beauty bottle, making it difficult for the brush head to adhere to the material at the bottom of the beauty bottle.

[0004] Therefore, improvements need to be made to this. Utility Model Content

[0005] The technical problem solved by the present invention is to address the defects existing in the above-mentioned prior art and provide a telescopic brush head applied to a beauty bottle to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: A telescopic brush head applied to a beauty bottle, comprising: a brush head body, a brush head is provided at the first end of the brush head body, a first hollow accommodating space is provided at the second end of the brush head body, and one or more radially extending protrusions are provided on the outside of the second end of the brush head body; an elastic member, the elastic member is placed in the first accommodating space; an end cover, the end cover is provided with a second hollow accommodating space, the end cover is sleeved on the second end of the brush head body through the second accommodating space, and the inner wall of the end cover is provided with a guide groove cooperating with the protrusion; wherein, under the elastic force of the elastic member, the end cover moves relative to the second end of the brush head body.

[0007] Furthermore, the elastic member is a spring.

[0008] Furthermore, the guide groove passes through the end cover.

[0009] Furthermore, the guide groove is arranged longitudinally.

[0010] Furthermore, the brush head body is provided with a radially arranged step, and the step is used to limit the downward movement distance of the end cover.

[0011] Furthermore, the outer peripheral surface of the end cap is provided with axially arranged ribs, and the ribs are used for assembling and fixing with the beauty bottle cap.

[0012] Compared with the prior art, the present invention has the following advantages: by adding an elastic member between the end cap and the brush head body, the end cap cooperates with the lid of the cosmetic bottle. When the lid is rotated open, the elastic member acts to extend the brush head body relative to the end cap, allowing the brush head on the brush head body to always be at the bottom of the cosmetic bottle. This avoids waste of raw materials and makes the operation of attaching raw materials more convenient.

[0013] Between the end cover and the brush head body, the convex portion provided on the brush head body cooperates with the guide groove on the end cover, making the movement more orderly and stable. BRIEF DESCRIPTION OF THE DRAWINGS
