Description

Technical Field

[0001] This technical solution relates to the field of cosmetic tools technology, specifically to a cosmetic applicator head. Background Technology

[0002] Cosmetic tools are products used to apply cosmetics evenly and precisely to specific areas of the skin or face using an applicator. For example, a lip gloss typically consists of a bottle containing the cosmetic, a cap screwed onto the top of the bottle to seal the opening, and an applicator. The brush head of the applicator is used to pick up the cosmetic from the bottle and apply it.

[0003] For example, Chinese patent CN207626758U discloses a new type of lip gloss bottle, including a bottle body, an outer cap, a brush rod, and a brush head. The outer cap is fitted onto the bottle body, the upper end of the brush rod is fixed inside the outer cap, the lower end of the brush rod extends into the bottle body, and a brush head is fixed at its lower end. A brush head mounting hole is opened axially on the lower end face of the brush rod, and a brush head connecting post is provided on the brush head, which is fixed in the brush head mounting hole.

[0004] In the design of the aforementioned new lip gloss bottle, the brush head is made of rigid or low-elasticity material. During application, it is difficult to provide effective real-time force feedback. The brush head itself lacks sufficient elastic deformation capacity and cannot adapt to the curvature of the lips or the amount of force applied by the user. This results in the brush head and the lip surface always being in hard contact, which limits the smoothness and adherence of the application. It can easily lead to inaccurate control of the amount used, reduced uniformity of the makeup effect, and reduced comfort and controllability during use. Summary of the Invention

[0005] This technical solution aims to improve the problem of uneven application and poor controllability caused by the lack of adaptive deformation ability due to excessive rigidity of the brush head. It provides a cosmetic applicator head.

[0006] The purpose of this technical solution is achieved as follows: A cosmetic applicator head includes a base for mounting on the brush handle of a matching cosmetic tool; The applicator is used to pick up and apply makeup. An elastomer has its two ends disposed on the base and the applicator head, respectively, and the applicator head is elastically connected to the base via the elastomer.

[0007] Through the above technical solution, when a cosmetic applicator head is in normal use, the applicator head is mounted on the cosmetic container via a base. After the applicator head picks up the makeup, during the process of the user applying pressure to the skin for application, the elastic body connecting the base and the applicator head provides elasticity, and the applicator head oscillates adaptively, thereby dynamically conforming to the facial contour curve. This elastic support and oscillation mechanism buffers the operating pressure, improves the fit between the applicator head and the skin, and makes the overall application operation more controllable.

[0008] Preferably, it further includes a connecting block, which is connected to the elastomer, and the applicator head is fixed on the connecting block.

[0009] With the above technical solution, the applicator head can be installed separately on the connecting block, and then the connecting block can be connected to the elastic element. Therefore, the connecting block and the applicator head can be made of different materials. For example, the connecting block can be made of a rigid material that can be firmly connected, and the applicator head can be made of a flexible material suitable for feeding, and brush bristles can be attached.

[0010] Preferably, the elastic body is a spring, and an annular groove one is formed at the end of the base, and an annular groove two is formed at the end of the connecting block. The two ends of the spring are respectively nested and fixed in the annular groove one and the annular groove two.

[0011] The above technical solution clarifies that the elastic body is a spring. The spring is fixed by having its two ends of the spring segments embedded in the first and second annular grooves, ensuring that the spring is securely confined between the base and the application head. This facilitates assembly, reduces costs, and the spring compresses and deforms to generate a rebound force, which drives the oscillation.

[0012] Preferably, one end of the elastomer is integrally connected to the base, and the other end of the elastomer is integrally connected to the connecting block.

[0013] Through the above technical solution, the base, elastomer and connecting block are designed as an integrated unit, eliminating the need for additional connection and assembly, reducing the number of parts and making the structure more stable.

[0014] Preferably, the connecting block includes a block body, the block body having a snap-fit ​​ring groove along its outer wall, the applicator having a cavity for inserting the connecting block, the cavity having a snap-fit ​​ring protruding along its inner wall, the snap-fit ​​ring fitting into the snap-fit ​​ring groove.

[0015] With the above technical solution, the block is inserted into the cavity, and the block is squeezed and passes through the locking protrusion in the cavity until it is inserted into the designated position. Then, the locking protrusion rebounds and embeds into the locking ring groove, forming a firm axial limit. The block is confined in the cavity, forming a firm circumferential fixation, making the assembly of the applicator head more convenient.

[0016] Preferably, the outer side of the applicator head has a recessed area and a raised ridge, the locking groove is located close to the recessed area, and the raised ridge has an applicator arc surface.

[0017] Through the above technical solution, the setting of the concave area makes the lower end of the applicator head form a raised structure, and the applicator arc surface of the ridge can better fit the facial contour, so as to achieve uniform and smooth material spreading.

[0018] Preferably, the connecting block further includes a second block, and the applicator head is provided with a corresponding locking groove. When the locking protrusion and the locking ring groove are engaged, the positioning block is locked in the locking groove.

[0019] Through the above technical solution, based on the special design of the recessed area on the outside of the applicator head, the cavity structure on one side of this area is difficult to extend. A locking groove with a size smaller than the cavity is opened at the end of the recessed area side of the applicator head. During assembly, the positioning block of the base is embedded in the matching locking groove, which further improves the overall assembly stability and connection reliability.

[0020] The key and beneficial technical effects of this technical solution compared to existing technologies are: 1. This technical solution connects the base and the applicator head separately through an elastomer, enabling the applicator head to swing in multiple directions relative to the base. During use, the applicator head adapts to the facial contours under pressure through the elastomer, improving fit and controllability, and achieving a uniform and smooth application effect.

[0021] 2. This technical solution uses a spring as the elastomer, with both ends of the spring nested in the annular groove one of the base and the annular groove two of the application head for fixation. This makes assembly convenient and reduces costs.

[0022] 3. This technical solution integrates the base, elastomer, and connecting block into a single unit, eliminating the need for additional connections and assembly, reducing the number of parts, and making the structure more stable. Attached Figure Description

[0025] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1: See Figure 1 A cosmetic applicator head includes a base 1, an applicator head 2, and an elastic body 3. The elastic body 3 is located between the base 1 and the applicator head 2. The elastic body 3 is preferably a spring 31, with its two ends fixed to the opposite ends of the base 1 and the applicator head 2, respectively. The base 1 can be mounted on the brush handle of a matching cosmetic tool. This mounting method is existing technology and will not be described in detail here. For example, a conventional lip gloss bottle includes a bottle body and a bottle cap. A brush handle extends and is fixed to the inner side of the bottle cap. The base 1 is mounted on the end of the brush handle. When the bottle cap is threaded to the bottle body, the applicator head 2 is correspondingly immersed in the lip gloss inside the bottle body. The applicator head 2 is used to pick up and apply makeup.

[0027] See Figure 2 It also includes a connecting block 11, which includes a block 111. The spring 31 is specifically fixed by having an annular groove 41 at the lower end of the base 1, which is opened along the outer peripheral wall of the end of the base 1. The end of the block 111 is correspondingly provided with an annular groove 42 along the outer peripheral wall. One end of the spring 31 is embedded in the annular groove 41 and the other end is embedded in the annular groove 42, so that the two ends of the spring 31 are respectively clamped to the opposite ends of the base 1 and the applicator head 2, thereby realizing the fixed connection between the base 1, the elastomer 3 and the applicator head 2.

[0028] The applicator head 2 is made of an elastic or non-elastic material, such as rubber, ceramic, metal, or plastic flocking. The applicator head 2 has a recessed area 91 and a raised ridge 92. The recessed area 91 is recessed on the outer side of the applicator head 2. This recessed design makes the two sides convex. The raised ridge 92 is located on the side of the recessed area 91 away from the spring 31. In conjunction with the recessed structure, the overall shape of the applicator head 2 is C-shaped. The raised ridge 92 has an applicating arc surface 10. This arc surface is easy to conform to the facial contours, giving the makeup good extensibility.

[0029] The specific work process of this plan is as follows: This technical solution involves mounting the applicator 1 onto a cosmetic container. After the applicator 2 picks up the makeup, during the application process when the user applies pressure to the skin, the elastic body 3 connecting the base 1 and the applicator 2 provides elasticity. This allows the applicator 2 to not only have a tendency to move away from the base 1, but also to generate adaptive oscillation, thereby dynamically conforming to the facial contour curve. This elastic support and oscillation mechanism buffers the operating pressure, improves the fit between the applicator 2 and the skin, and makes the overall application operation more controllable.

[0030] Example 2: See Figure 3 and Figure 4 A cosmetic applicator head, which differs from Embodiment 1 in that the base 1 is integrally connected to an elastomer 3, and the connecting block 11 is integrally connected to the end of the elastomer 3 away from the base 1.

[0031] See Figure 5 , Figure 6 and Figure 7 The applicator head 2 has a cavity 6, the size of which matches the connecting block 13. The connecting block 11 also includes a second block 112, which protrudes from the end face of the elastic body 3 near the connecting block 13. The applicator head 2 also has a locking groove 8 corresponding to the position of the positioning block 7. One side of the locking groove 8 is connected to the cavity 6. The locking groove 8 is located near the recessed area 91. Since the recessed area 91 has occupied a lot of space in the vertical direction, the groove depth of the locking groove 8 is less than the depth of the cavity 6. The first block 111 has a locking ring groove 51, which is opened on the outer peripheral wall of the first block 111. The cavity 6 has a corresponding locking protrusion ring 52 protruding along the inner side wall. The locking protrusion ring 52 is adapted to the locking ring groove 51. When the first block 111 is embedded in the cavity 6, the locking protrusion ring 52 and the locking ring groove 51 are engaged.

[0032] The specific work process of this plan is as follows: This technical solution involves embedding block 111 into cavity 6. Since the applicator head 2 is made of elastic material, block 111 compresses and holds the snap ring 52 until it is inserted into the designated position. At this point, the snap ring 52 springs back and embeds into the snap ring groove 51, forming a firm axial limit. Block 111 is confined within the matching cavity 6. Meanwhile, block 212 is embedded in the locking groove 8, forming a firm circumferential fixation. This makes the assembly of the applicator head 2 more convenient.
