[0002] Makeup brushes are common makeup tools used for applying makeup, contouring, and foundation. They typically consist of a handle and a brush head. The brush head, made of bristles, is used to pick up makeup and apply it evenly to the face. Traditional makeup brushes usually have a fixed brush head structure, with a rigid connection between the brush head and the handle. During use, the brush head's posture is fixed, and the user can only adjust the direction and angle of contact between the brush head and the face by changing the angle of their wrist.

[0003] Shortcomings of existing technology: 1. Insufficient freedom of angle adjustment Existing makeup brushes lack a rotating mechanism and a reliable angle positioning structure. When the user applies pressure, they cannot maintain stability at different angles, resulting in a poor user experience.

[0004] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0022] The positioning mechanism 7 includes a first toothed ring coaxially disposed on both sides of the ear seat 12 of the brush head seat 4 and a second toothed ring disposed on the inner side of the fork-shaped support 10. The first toothed ring and the second toothed ring mesh with each other to form a segmented angle positioning damping force to prevent the brush head assembly 3 from loosening during use.

[0023] The bristle bundle 5 is a detachable structure. The bristle bundle 5 is fixed to the replaceable brush head base 4 and is detachably connected to the inner wall of the brush head base 4 through interlocking flanges and slots for easy replacement and cleaning.

[0024] The upper end of the handle 1 is provided with a connecting groove that mates with the lower end of the connecting seat 2. The outer surface of the handle shell is provided with wavy anti-slip ribs along the axial direction, and an elliptical operating area is formed in the middle to improve grip stability.

[0025] The handle shell adopts a secondary injection molding structure with a hard plastic matrix and an overmolded elastomeric anti-slip layer. The bristle bundle 5 is made of synthetic fiber and has an overall elliptical cross-section arc shape to fit the curved surface of the face.

[0026] The principle of this utility model is as follows: The handheld movable head makeup brush of this utility model is mainly composed of a handle 1, a connecting seat 2, a brush head assembly 3, and a positioning mechanism 7.

[0027] The brush head assembly 3 can rotate relative to the connecting seat 2 about the transverse pivot via the pivot hinge assembly 6, thereby achieving adjustment of the brush head angle.

[0028] When the user applies external force to change the direction of the brush head, the brush head base 4 can rotate relative to the connecting base 2 to a suitable angle, and the angle position is stably maintained by the segmented positioning mechanism 7 set between the two, so that the brush head can adapt to different facial angles for even makeup application.

[0029] 1. Working principle of the hinge assembly 6 The pivot hinge assembly 6 consists of a left pivot pin 8, a right pivot pin 9, a fork-shaped support 10, and an ear seat 12. The fork-shaped support 10 is formed at the upper end of the connecting seat 2, and the two sides are provided with the first shaft hole 11 coaxial with the left shaft pin 8 and the right shaft pin 9; The ear seat 12 is located at the lower end of the brush head seat 4 and has a corresponding second shaft hole 13; After the left shaft pin 8 and the right shaft pin 9 pass through the first shaft hole 11 and the second shaft hole 13, the brush head seat 4 can form a rotatable connection with the connecting seat 2. The anti-slip ring set at the outer end of the pin serves to limit and prevent slippage, ensuring that the brush head seat 4 will not loosen or shift during long-term use and rotation.

[0030] In actual use, when the user adjusts the brush head angle, the left shaft pin 8 and the right shaft pin 9 serve as the pivot points to provide fulcrum, allowing the brush head seat 4 to rotate smoothly around the transverse axis. The rotational friction is controlled by the clearance between the shaft pin and the shaft hole to achieve smooth angle adjustment.

[0031] 2. Working principle of the segmentation and positioning mechanism 7 The grading and positioning mechanism 7 consists of a first gear ring and a second gear ring, which are respectively located on both sides of the ear seat 12 of the brush head seat 4 and the inside of the fork-shaped support 10, and maintain a coaxial meshing relationship.

[0032] When the brush head holder 4 rotates around the shaft, the first gear ring drives the second gear ring to produce tooth surface meshing and sliding, and the friction between the teeth generates positioning damping force. The spacing between the toothed rings is designed as a segmented structure, allowing the brush head to stop at multiple preset angle positions. When the user stops applying force, the frictional damping between the toothed rings prevents the brush head assembly 3 from rotating automatically due to inertia or vibration, maintaining a stable angle.

[0033] 3. Working principle of the detachable brush head structure The bristle bundle 5 is fixed to the replaceable brush head holder 4, and the two are detachably connected by a snap-fit ​​flange and a slot. When the brush head needs to be replaced or cleaned, the user can disengage the snap-fit ​​part by slightly rotating or pulling it. After cleaning or replacing the bristle bundle 5, simply insert the brush head seat 4 in the original direction and tighten it to re-engage the flange with the slot.

[0034] 4. Ergonomics and Handle 1 Structure and Fit Principle The upper end of the handle 1 is connected to the lower end of the connecting seat 2 for installation, so as to achieve overall assembly and positioning.

[0035] The wavy anti-slip ribs arranged axially on the surface of the handle housing provide friction and prevent slippage; The oval-shaped recessed operating area in the middle conforms to the force distribution of the fingers, making the grip more stable; The handle 1 adopts a two-stage injection molding structure with a hard plastic matrix and an elastomer anti-slip layer, which not only ensures strength but also improves the grip and appearance.

[0036] 5. The principle of bristle tuft 5 adhering to the skin and applying makeup. The bristle bundle 5 is made of synthetic fiber and has an overall elliptical cross-section. The bristles are soft and moderately dense, allowing for even contact with facial skin during makeup application; The elliptical arc structure matches the curvature of the face, allowing it to fit naturally in different areas and achieve a continuous, smooth makeup effect.

[0037] 6. Comprehensive Work Process Description During use, the user holds the handle 1 and grips it stably through the wavy anti-slip ribs and the recessed operating area; The brush head angle can be adjusted via the pivot hinge assembly 6 according to the shape of different areas of the face and the direction of force applied. The segmented positioning mechanism 7 provides damping retention at each angle position, ensuring that the brush head remains stable in the selected position.

[0038] When the bristle bundle 5 comes into contact with the skin, its flexible arc structure allows cosmetics to be evenly distributed on the face, achieving a natural and fitting makeup effect. After use, the brush head can be quickly disassembled and cleaned using the snap-fit ​​mechanism to maintain cleanliness and hygiene.

[0039] In summary, this makeup brush achieves an overall working principle of adjustable angle, stable positioning, reliable structure, convenient cleaning, and comfortable operation through the comprehensive cooperation of the mechanical rotating shaft 6, toothed ring positioning mechanism 7, detachable brush head base 4, and ergonomic handle 1.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
