Description

Technical Field

[0001] This utility model relates to the field of cosmetic brush technology, and more specifically, to an ultra-fine cosmetic brush. Background Technology

[0002] Eyebrow pencils are a common makeup tool used to shape and define eyebrows, helping to correct uneven thickness and asymmetry. Fine-tipped eyebrow pencils allow for more precise application, creating fuller, brighter brows. They produce more natural-looking brows, making them easier for both experienced users and beginners to achieve a satisfactory result with every stroke.

[0003] However, traditional eyebrow pencils require sharpening like a pencil, and the fine tip is relatively troublesome to handle and prone to breakage. Current makeup pencils use adjustable fine tips, with the tip housed within the pencil body; however, the exposed tip is extremely fragile and easily breaks. If the exposed tip is short, it becomes relatively difficult to apply precisely. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an ultra-fine cosmetic brush that solves the problems of troublesome material adjustment and easy breakage of the material head.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An ultra-fine cosmetic brush includes a material body, a protective sleeve, a brush tip, a mounting sleeve, and a brush body. The lower half of the mounting sleeve is inserted into and fixed to the top of the brush body. A mounting assembly is fixed inside the mounting sleeve. The bottom end of the material body is vertically inserted into the top of the mounting assembly. The brush tip includes an upper conical brush tip and a lower insert cylinder. The insert cylinder is rotatably inserted into the upper half of the mounting sleeve. The protective sleeve includes a protective sleeve head, a cylindrical movable sleeve, and a square movable sleeve arranged sequentially from top to bottom. The protective sleeve is inserted into the brush tip from the bottom and extends the protective sleeve head to the outside of the top of the conical brush tip. A helical spring is installed on the mounting assembly. The bottom of the square movable sleeve abuts against the top of the helical spring. The top end of the material body passes through the protective sleeve and extends into the protective sleeve head.

[0007] The present invention is further configured such that: the installation assembly includes an installation column and an adjusting bolt rod, the installation column is fixed in the lower half of the installation cylinder, the adjusting bolt rod includes a bolt rod and a sleeve rod, the top end of the bolt rod is connected to the bottom end of the sleeve rod, the bolt rod is spirally inserted from the center position of the top of the installation column, and the bottom end of the material is inserted into the top of the sleeve rod.

[0008] The present invention is further configured such that: the sleeve rod is a square insert rod, and the top end of the sleeve rod is movably inserted into the interior of the square movable cylinder from the bottom.

[0009] The present invention is further configured such that: multiple limiting protrusions are provided on the outer wall of the insertion cylinder and the inner wall of the upper half of the mounting cylinder.

[0010] The present invention is further configured such that: the outer diameter of the bottom end of the cone-shaped pen tip is the same as the outer diameter of the top end of the mounting cylinder; the outer wall of the cone-shaped pen tip and the upper outer wall of the mounting cylinder are inclined surfaces with the same inclination; and the upper outer wall of the mounting cylinder is provided with semi-circular protrusions evenly distributed around the circumference.

[0011] The present invention is further configured such that the top of the protective sleeve is an annular arc surface.

[0012] The present invention is further configured such that the protective cylinder is made of transparent plastic.

[0013] This utility model has the following beneficial effects:

[0014] 1. When not applying makeup, the product head is inside the protective cap. When applying makeup, the protective cap will press down and retract inwards towards the tip when it touches the makeup area, so that the product head touches the makeup area. Due to the protection of the protective cap, the product head is not easy to break during makeup application, effectively protecting the product head. In addition, the protective cap is transparent, so it does not affect the observation of the product head position during makeup application, and the makeup effect will not be affected by the protective cap.

[0015] 2. Adjusting the material extension is simple; just rotate the tip of the cone. The operation is easy and the length is controllable. Attached Figure Description

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] Specifically, it refers to an ultra-fine cosmetic brush, including a material body 5, a protective tube, a brush tip, a mounting tube 2, and a brush body 3. The lower half of the mounting tube 2 is inserted into and fixed from the top of the brush body. An installation component is fixed inside the mounting tube 2. The bottom end of the material body is vertically inserted into the top of the installation component. The brush tip includes an upper conical brush tip 1 and a lower insert cylinder 11. The insert cylinder 11 is rotatably inserted into the upper half of the mounting tube 2. The protective tube includes a protective sleeve 4, a cylindrical movable tube 41, and a square movable tube 42 connected sequentially from top to bottom. The protective tube is inserted into the interior from the bottom of the brush tip and extends the protective sleeve 4 to the outside of the top of the conical brush tip 1. A spiral spring 6 is installed on the mounting component. The bottom of the square movable tube 42 abuts against the top of the spiral spring 6. The top end of the material body 5 passes through the protective tube and extends into the protective sleeve 4.

[0027] When not applying makeup, the top of the material 5 can be tucked into the tip of the cone-shaped pen by rotating the tip 1, or the exposed protective cap 4 can be used to protect the top of the material 5.

[0028] When applying makeup, the top of the product 5 is inside the protective cap 4. When applying makeup, the protective cap 4 is touched and pushed into the cone-shaped pen tip 1. Because the elasticity of the spiral spring is not high, it is easy to press down the protective cap 4 to expose the top of the product 5 for makeup application. During the makeup process, when the product 5 is bent to the side by force, the protective cap 4 is not easy to bend to the side, effectively protecting the product 5 from being broken.

[0029] The square movable tube 42 is slightly wider than the cylindrical movable tube 41, so that the square movable tube 42 cannot be inserted into the cone-shaped pen tip 1 into which the cylindrical movable tube 41 is inserted, thus ensuring that the protective cap 4 protrudes beyond the top of the cone-shaped pen tip 1 by a limited length.

[0030] The installation assembly includes an installation column 8 and an adjustment bolt rod. The installation column 8 is fixed inside the lower half of the installation cylinder 2. The adjustment bolt rod includes a bolt rod 71 and a sleeve rod 7. The top end of the bolt rod 71 is connected to the bottom end of the sleeve rod 7. The bolt rod 71 is spirally inserted from the center position of the top of the installation column 8. The bottom end of the material body 5 is inserted into the top of the sleeve rod 7.

[0031] The sleeve rod 7 is a square insert rod, and the top end of the sleeve rod 7 is inserted into the square movable cylinder 42 from the bottom.

[0032] The material body 5 has a certain length, making it convenient for multiple uses without replacement. When the head of the material body 5 is shortened due to makeup application, the cone-shaped pen tip 1 is rotated. Since the inside of the insert cylinder 11 has a square hole that matches the square outer wall of the square movable cylinder 42, the square movable cylinder 42 is rotated. The sleeve rod 7 is also square and rotates synchronously, causing the bolt rod 71 to rotate inside the mounting column 8. This allows the bolt rod 71 to rise and fall during rotation, thereby adjusting the rise and fall of the material body 5.

[0033] Multiple limiting protrusions 111 are provided on the outer wall of the insertion cylinder 11 and the inner wall of the upper half of the mounting cylinder 2. The limiting protrusions 111 can deform. After insertion, the insertion cylinder 11 and the upper limiting protrusions 111 on the inner wall of the mounting cylinder 2 will limit each other, making it difficult for the insertion cylinder 11 to come out, but ensuring the rotation effect.

[0034] The outer diameter of the bottom end of the cone-shaped pen tip 1 is the same as the outer diameter of the top end of the mounting cylinder 2. The outer wall of the cone-shaped pen tip 1 and the upper outer wall of the mounting cylinder 2 are inclined surfaces with the same angle. The upper outer wall of the mounting cylinder 2 is provided with semi-circular protrusions 20 evenly distributed around its circumference. This design ensures smoothness and ease of grip. The semi-circular protrusions 20 prevent slippage when held in this position, and also facilitate control of force.

[0035] The top of the protective cap 4 is an annular arc-shaped top 43. It feels more comfortable when it touches the skin, and is more comfortable than a flat top with edges.

[0036] The protective tube is made of transparent plastic. It allows for easy penetration through the top of the product, facilitating control over the makeup effect.
