Description

Technical Field

[0001] This utility model relates to the field of cosmetic equipment technology, specifically to a round-headed movable-head makeup brush. Background Technology

[0002] Makeup brushes, as commonly used beauty tools in the makeup process, are widely used for applying various cosmetics such as foundation, blush, highlighter, and contour. Existing makeup brushes typically consist of a handle and a brush head, with the brush head comprising a brush head base for holding the bristles and a bristle tuft fixed within it. The shape, density, and material of the bristle tuft directly affect the evenness and adherence of the makeup application; therefore, when designing makeup brushes, people often pay attention to the selection of bristle materials and the shaping process.

[0003] The shortcomings of existing technology: 1. Fixed structure, angle cannot be adjusted. Traditional makeup brushes typically use a fixed connection between the handle and the brush head, which means the brush head angle cannot be adjusted. Users need to frequently change their wrist position to adapt to different makeup angles, which can easily cause fatigue and makes it difficult to ensure that the bristles fit the skin optimally.

[0004] 2. Lacks an angle positioning mechanism, resulting in unstable adjustment. While some improved movable-head makeup brushes feature a rotatable connection between the brush head and handle, these are typically simple rotating shaft structures lacking effective positioning or damping mechanisms. During use, the brush head is prone to loosening, unstable rotation, or wobbling, affecting makeup application accuracy and the user experience.

[0005] 3. Insufficient grip comfort Some makeup brush handles are made of hard plastic or metal, with a smooth and slippery surface. Prolonged use can cause sweaty or tired hands, and they lack ergonomic anti-slip designs.

[0006] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0007] In view of the problems existing in the prior art, this utility model provides a round-headed movable makeup brush.

[0008] To achieve the above objectives, the specific solution of this utility model is as follows: This utility model provides a round-headed, movable-head makeup brush, comprising: handle; A connecting seat is provided at the upper end of the handle; and a brush head assembly disposed on the connector; The brush head assembly includes a cup-shaped brush head seat that accommodates a bristle bundle and a bristle bundle that is fixedly connected to the brush head seat. The exposed end of the bristle bundle forms a dome-shaped round head shape. The brush head holder and the connecting seat are rotatably connected by a pivot hinge assembly around a pivot axis that is arranged laterally. Furthermore, a positioning mechanism is provided between the brush head base and the connecting base to position and hold the brush head assembly at multiple angular positions.

[0009] Furthermore, the pivot hinge assembly includes a first pivot pin, a fork-shaped support disposed at the upper end of the connecting seat, and an ear seat disposed at the lower end of the brush head seat; The fork-shaped support has first shaft holes on both sides, and the ear seat has a second shaft hole that is coaxially engaged with the first shaft holes. The ear seat is disposed between the fork-shaped supports. The first shaft pin passes through the first shaft hole and the second shaft hole in sequence to form the rotating shaft arranged in the transverse direction.

[0010] Furthermore, the positioning mechanism includes a first toothed ring disposed on the outside of the ear seat and coaxial with the rotating shaft, and a second toothed ring disposed on the inside of the fork-shaped support and meshing with the first toothed ring. The first toothed ring and the second toothed ring mesh with each other to form a segmented angular positioning and provide damping force, thereby preventing the brush head assembly from loosening during use.

[0011] Furthermore, the bristle bundle is a detachable structure. The bristle bundle is installed in the replaceable brush head holder and is detachably connected to the inner wall of the brush head holder through interlocking flanges and slots, so as to facilitate removal for cleaning or replacement of different types of bristle bundles.

[0012] Furthermore, the handle adopts a secondary injection molding structure, and its outer wall is covered with a molded elastomeric anti-slip layer; The bristles are made of synthetic fiber and have an elliptical cross-section and an arc shape to better fit the curves of the face.

[0013] Furthermore, a limiting structure is provided between the connecting seat and the brush head seat. The limiting structure is formed by the cooperation of a limiting boss provided on the connecting seat and a limiting groove provided on the brush head seat, so as to limit the rotation range of the brush head assembly relative to the connecting seat to 0° to 90°.

[0014] Furthermore, the inner end face of the cup-shaped brush head seat is an arc transition surface that matches the shape of the root of the bristle bundle. The cup-shaped brush head holder has an annular pressure ring at its rim. The annular pressure ring is connected to the brush head holder by screwing or snapping and presses down on the root of the bristle bundle.

[0015] The technical solution of this utility model has the following beneficial effects: 1. Achieve adjustable brush head angle and strong fit. By setting a pivot hinge assembly between the connector and the brush head, the brush head assembly can rotate and adjust around the horizontal pivot. Users can freely adjust the brush head angle according to different parts of the face, thereby achieving smooth and even makeup application to curved areas such as the nose, chin, and cheekbones, significantly improving the precision and naturalness of makeup.

[0016] 2. Possesses segmented positioning and damping stability. By setting a first toothed ring and a second toothed ring that mesh with each other between the fork-shaped support and the ear seat, a segmented angle positioning structure is formed, and a moderate damping force is generated between the meshing, which can effectively prevent the brush head from loosening or drifting due to external force during use, and ensure the stability and repeatability of angle adjustment.

[0017] 3. Provides limit protection to prevent damage from excessive rotation. A limiting structure with a limiting boss and a limiting groove is set between the connecting seat and the brush head seat to limit the rotation angle within the range of 0° to 90°, which can avoid structural damage or loosening caused by excessive rotation during use and improve overall durability.

[0018] 4. Comfortable grip and excellent anti-slip effect The handle is formed using a secondary injection molding process, with an outer layer covered with an elastomer anti-slip layer to improve grip friction and comfort. It is not easy to slip even when hands are wet, making it convenient for long-term use and precise operation. Attached Figure Description

[0024] Combination Figures 1-4 As shown, this utility model provides a round-headed movable makeup brush, comprising: Handle 1; The connecting seat 2 is provided at the upper end of the handle 1; And the brush head assembly 3 disposed on the connector 2; The brush head assembly 3 includes a cup-shaped brush head seat 4 that accommodates the bristle bundle 5 and the bristle bundle 5 that is fixedly connected to the brush head seat 4. The exposed end of the bristle bundle 5 forms a dome-shaped round head shape. The brush head holder 4 and the connecting seat 2 are rotatably connected by a pivot hinge assembly 6 around a pivot arranged in the horizontal direction. Furthermore, a positioning mechanism 7 is provided between the brush head base 4 and the connecting base 2 to position and hold the brush head assembly 3 at multiple angular positions.

[0025] The pivot hinge assembly 6 includes a first pivot pin 8, a fork-shaped support 9 disposed on the upper end of the connecting seat 2, and an ear seat 10 disposed on the lower end of the brush head seat 4. The fork-shaped support 9 has first shaft holes 11 on both sides, and the ear seat 10 has a second shaft hole 12 that is coaxially engaged with the first shaft holes 11. The ear seat 10 is disposed between the fork-shaped supports 9. The first shaft pin 8 passes through the first shaft hole 11 and the second shaft hole 12 in sequence to form the rotating shaft arranged in the transverse direction.

[0026] The positioning mechanism 7 includes a first toothed ring 13 disposed on the outside of the ear seat 10 and coaxial with the rotating shaft, and a second toothed ring 14 disposed on the inside of the fork-shaped support 9 and meshing with the first toothed ring 13. The first toothed ring 13 and the second toothed ring 14 mesh with each other to form a segmented angular positioning and provide damping force, thereby preventing the brush head assembly 3 from loosening during use.

[0027] The bristle bundle 5 is a detachable structure. The bristle bundle 5 is installed in the replaceable brush head seat 4 and is detachably connected to the inner wall of the brush head seat 4 through interlocking flanges and slots, so as to facilitate removal for cleaning or replacement of different types of bristle bundles 5.

[0028] The handle 1 adopts a secondary injection molding structure, and its outer wall is covered with a molded elastomer anti-slip layer 15. The bristle bundle 5 is made of synthetic fiber and has an elliptical cross-section and an arc shape to better fit the curvature of the face.

[0029] A limiting structure is provided between the connecting seat 2 and the brush head seat 4. The limiting structure is formed by the cooperation of the limiting boss 16 provided on the connecting seat 2 and the limiting groove 17 provided on the brush head seat 4, so as to limit the rotation range of the brush head assembly 3 relative to the connecting seat 2 to 0°~90°.

[0030] The inner end face of the cup-shaped brush head holder 4 is a rounded transition surface and matches the shape of the root of the bristle bundle 5. The cup-shaped brush head base 4 has an annular pressure ring at its rim. The annular pressure ring is connected to the brush head base 4 by screwing or snapping and presses down on the root of the bristle bundle 5.

[0031] The principle of this utility model is as follows: When a user holds the handle 1 to perform makeup application, the connecting seat 2 at the upper end of the handle 1 is rotatably connected to the brush head assembly 3 via a pivot hinge assembly 6. The pivot hinge assembly 6 consists of a fork-shaped support 9, an ear seat 10, and a first pivot pin 8 passing through both, allowing the brush head assembly 3 to rotate laterally relative to the handle 1. During use, the user can adjust the posture of the brush head assembly 3 by slightly rotating it according to the curvature of different parts of the face and the angle of application, ensuring that the contact surface of the bristles 5 always maintains optimal contact with the skin surface, thereby achieving a more even and natural makeup application effect.

[0032] When the brush head assembly 3 is rotated to a suitable angle, the first retaining ring 13 located on the outside of the ear seat 10 and the second retaining ring 14 located on the inside of the fork-shaped support 9 engage with each other. Through the segmented structure between the rings and the friction damping, a stable positioning and holding effect can be formed at the predetermined angle position, preventing the brush head from automatically swinging or rebounding due to external force during the makeup process, thus ensuring the stability and accuracy of use.

[0033] To prevent structural damage from excessive rotation, the limiting boss 16 and the limiting groove 17 between the connecting seat 2 and the brush head seat 4 cooperate to physically limit and control the rotation angle of the brush head assembly 3, limiting its rotation range to between 0° and 90°. This not only meets the usage requirements at different angles but also effectively prevents the brush head from becoming loose due to excessive rotation during use or cleaning.

[0034] The bristle bundle 5 is installed inside the cup-shaped brush head base 4 and is held in place by screwing or snapping together with an annular pressure ring. The inner end face of the cup-shaped brush head base 4 is an arc transition surface that matches the shape of the root of the bristle bundle 5. This provides uniform support during holding, making the bristles dense and stable, thus ensuring a smooth touch and even force during makeup application.

[0035] When the bristle bundle 5 needs cleaning or replacement, the user simply needs to loosen the ring or release the locking mechanism to remove the bristle bundle 5 from the brush head holder 4. Bristle bundles 5 of different shapes, hardness, or density can be interchanged to adapt to different makeup needs such as foundation, blush, and highlighter, making them flexible and convenient to use.

[0036] In addition, the handle 1 adopts a secondary injection molding structure, and the outer wall is covered with a molded elastomer anti-slip layer 15, which can provide a comfortable grip and prevent hand slippage during use, making the operation more stable.

[0037] In summary, this utility model, through the coordinated structure of adjustable pivot, toothed ring positioning, limit protection, detachable bristles, and anti-slip handle, achieves a comprehensive technical effect of adjustable makeup angle, stable posture, comfortable use, and convenient cleaning, significantly improving the functionality and user experience of makeup brushes.

[0038] 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. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the protection scope of the present utility model.
