Description

Technical Field

[0001] This utility model relates to the field of shaver technology, and in particular to a ball-bearing blade mesh structure, a blade head assembly, and a shaver. Background Technology

[0002] The blades of rotary electric shavers currently on the market have simple structures, all being rotating bodies with slits on the foil for hair entry. During use, as the foil contacts the skin and moves back and forth, the large contact area between the blade and the skin, coupled with the skin's flexibility, creates a "head wave phenomenon" (skin pushing and piling up), resulting in high resistance, low smoothness, and a poor shaving experience.

[0003] To address the issue of resistance caused by friction between the mesh and the skin, existing technologies typically employ the following two solutions: 1. Apply a low-friction coefficient coating to the mesh surface.

[0004] 2. The mesh structure is optimized from a flat surface to a curved surface to reduce the contact area with the skin.

[0005] However, both of these methods still present significant resistance to movement, especially when dealing with oily or sweaty skin, resulting in limited improvement. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this utility model proposes a ball-bearing shaving foil structure, which reduces friction between the foil surface and the skin by setting the rolling of the balls, thereby improving the smoothness of shaving.

[0007] This utility model also provides a razor head assembly and a razor using the above-mentioned ball-bearing foil structure, which improves the smoothness of movement, shaving comfort, reduces redness and irritation, and enhances shaving efficiency and fit.

[0008] The technical solution adopted in this utility model is: A ball bearing type blade mesh structure includes a blade mesh body. A decorative piece is provided on the central platform of the blade mesh body. One or more balls are protruding from the decorative piece. The balls are fixed in a fixing groove between the central platform and the decorative piece and are supported by the central platform.

[0009] Furthermore, there is a fitting gap between the fixing groove and the ball, which facilitates the flexible rolling of the ball.

[0010] Furthermore, the fixing groove is an annular groove, a hollowed-out groove, or a recessed spherical groove.

[0011] Furthermore, the ball is a spherical structure with a diameter ranging from 1.0 to 6.0 mm.

[0012] Furthermore, the ball is a rolling element made of ceramic, stainless steel, or plastic.

[0013] Furthermore, the balls are arranged on the decorative piece at equal intervals, along the axis, or in a ring.

[0014] Furthermore, the decorative piece is fixed to the central table surface by adhesive bonding, central shaft fixing, or fastening.

[0015] Furthermore, the inner and outer rings of the blade mesh body are provided with evenly distributed ball bearings.

[0016] The cutter head assembly includes the ball-bearing cutter head structure described in any of the above technical solutions.

[0017] A razor, including the ball-bearing foil structure described in any of the above technical solutions.

[0018] The beneficial effects of this utility model are: 1. Improve smoothness of movement: Eliminate the "head wave phenomenon". When moving with a traditional shaver, the skin's softness accumulates, forming a resistance wave (head wave phenomenon). The ball bearing avoids the resistance caused by the skin pushing, achieving resistance-free gliding.

[0019] 2. Improve shaving comfort: The beneficial roller arrangement can provide a warming and massaging effect on the skin.

[0020] 3. Reduce redness and irritation: Rolling friction replaces sliding friction, significantly reducing mechanical pulling on sensitive skin and reducing redness and burning sensation after shaving.

[0021] 4. Improve shaving efficiency and fit: The roller ball helps the foil adapt more flexibly to the contours of the face (such as the curves of the chin and neck), reducing blind spots during shaving. Attached Figure Description

[0039] Example 1

[0040] Reference Figure 1 , Figure 2This embodiment provides a ball-bearing blade mesh structure, including a blade mesh body 1. A decorative piece 3 is disposed on the central platform 2 of the blade mesh body 1. One or more balls 4 protrude from the decorative piece 3. The balls 4 are fixed in a fixing groove 5 between the central platform 2 and the decorative piece 3 and are supported by the central platform 2. That is, the balls 4 in this embodiment are embedded and can roll freely. The partial protrusion of the balls 4 from the upper surface of the decorative piece 3 forms a rolling support point.

[0041] In this embodiment, five ball bearings 4 protrude from the decorative piece 3. The ball bearings 4 are arranged in a ring with equal spacing. Each ball bearing 4 has a spherical structure with a diameter ranging from 1.0 to 6.0 mm. The ball bearings 4 are rolling elements made of ceramic, stainless steel, or plastic. Alternatively, the ball bearings 4 can be arranged irregularly.

[0042] In this embodiment, the fixing groove 5 and the ball 4 have a fitting clearance to facilitate the flexible rolling of the ball 4. The fixing groove 5 is an annular groove, see... Figure 3 As shown; of course, the fixing groove 5 can also be a hollow groove; of course, the fixing groove 5 can also be a recessed spherical groove. The fixing groove 5 can be formed by stamping in one step.

[0043] In this embodiment, the decorative piece 3 is fixedly connected to the central platform 2 via a central shaft 6. This can be achieved by bonding the central shaft 6 to the shaft hole using liquid adhesive, thereby fixing the ball bearing 4 within the fixing groove 5 between the blade and the decorative piece 3. Alternatively, the decorative piece 3 can be fixed by bonding its back to the central platform 2. The decorative piece 3 and the central platform 2 can also be connected using other fixing methods such as laser engraving or riveting.

[0044] This invention features embedded ball bearings 4 on the shaving net, which transforms the sliding friction between the shaving net and the skin into rolling friction, thereby eliminating the "head wave phenomenon," significantly reducing mechanical pulling on sensitive skin, reducing redness and burning sensation after shaving, and helping the shaving net to more flexibly adapt to facial contours (such as the curves of the chin and neck), reducing shaving dead angles.

The back of the decorative piece 3 is provided with several fasteners 7, and several corresponding fastening holes are punched on the corresponding central platform 2. The ball bearings 4 are fixed in the fixing groove 5 formed between the decorative piece 3 and the central platform 2 by a fastening fixing method. The fixing groove 5 can also be a hollow groove.
