Description

Technical Field

[0001] This utility model belongs to the field of cutting tool processing technology, specifically relating to a stamped cutting tool mesh. Background Technology

[0002] The stamped foil is an important component of an electric shaver. Its main function is to conform to the skin, guide the hair through the mesh, and remove the hair by cutting it based on the movement of the blades.

[0003] Currently, stamping cutter nets include a cutter net body with mesh openings. The front of the cutter net body forms a skin-contact surface, and the back forms a cutting surface. Simultaneously, the cutting surface forms a cutting edge from the edge of the mesh openings. Then, the moving blade and the moving cutting edge perform shearing to remove burrs. That is, the moving blade needs to conform to the entire back (cutting surface) to form the moving shear. However, in actual operation, the following technical defects exist: 1) The moving blade not only contacts the cutting edge but also the entire back side. Therefore, during the cutting motion of the moving blade, the temperature of the blade mesh rises, which in turn affects the feel on the skin. 2) Because the blade is flush with the back, the cutting depends entirely on the movement of the blade. If the hair is thick, it will not only cause a cutting edge, but also pull the hair and cause pain. There will still be stubble left after shaving, resulting in a seriously poor shaving experience. 3) The front side is smooth, and the connection between the two meshes is relatively weak. In order to provide a better contact effect, the outer edge of the mesh needs to be optimized. Otherwise, during the contact with the skin, not only will the hair not be able to be smoothly guided, but the edge of the mesh will also increase the risk of scratches or abrasions to the skin. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved stamping cutter head.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A stamped blade mesh includes a blade mesh body with mesh openings, wherein the front side of the blade mesh body is a skin-feel contact surface. In particular, the mesh openings are stamped from the front side to the back side, and the formed skin-feel contact surface is based on the stamping concavity and the edges of each mesh opening are rounded. The mesh opening edges punched from the back side form mesh opening cutting portions protruding from the back side, wherein the mesh opening cutting portions are aligned with the cutting edge face away from the front side to form a cutting surface that matches the moving blade.

[0006] Preferably, the length of the mesh cutting edge is less than the thickness of the blade body. This avoids excessively long protrusions formed during stamping, which not only affect the performance of the mesh cutting edge itself but also directly impact the shearing effect achieved through the interaction of the moving blades.

[0007] Furthermore, the length of the mesh cutting edge is 1 / 5 to 1 / 3 of the thickness of the blade body. In some specific embodiments, the length of the mesh cutting edge is 3 / 11 of the thickness of the blade body. This appropriate length and thickness matching provides optimal cutting performance.

[0008] According to a specific embodiment and preferred aspect of this utility model, the radius (R) of the rounded corner transition is ≤10μm. Based on this limitation of the radius (R), not only can the skin be brought close to or inserted into the mesh to form a cut at the hair root position, but the rounded corner can also more smoothly guide the hair into the mesh (higher guide rate). Furthermore, since the radius (R) is formed during stamping, the deformation caused by stamping can be fully utilized to improve the hair entry and shaving quality of the foil.

[0009] According to another specific embodiment and preferred aspect of this utility model, the connecting portions between two adjacent mesh openings are kept flush to form a skin-feeling contact surface. The skin-fitting effect created by this flush connection improves tactile comfort.

[0010] In some specific implementations, the cutting surface is parallel to the skin-feel contact surface. This parallelism avoids unevenness in the skin-feel contact surface caused by the mesh cutting edge mating with the moving blade.

[0011] According to another specific embodiment and preferred aspect of this utility model, the stamped mesh is distributed in an array. The array-layout mesh allows for relatively uniform introduction of hair fibers.

[0012] Preferably, the array includes a first array and a second array, wherein the mesh openings of the first array and the second array are staggered. This staggered arrangement of multiple arrays results in a denser mesh distribution, which is more conducive to the introduction of hairs.

[0013] In some specific implementations, the row spacing of the first array and the second array are equal, and the column spacing of the first array and the second array are equal.

[0014] Preferably, the center-to-center distance between two adjacent rows of meshes in the row spacing direction is L1, and the center-to-center distance between two meshes in each row in the column spacing direction is L2, where L1 > L2. Further limitations on the row and column spacing of the array allow for a more compact mesh layout, enabling the introduction of hairs into the mesh from multiple angles.

[0015] In addition, assembly holes are provided on opposite sides of the blade body. These assembly holes facilitate the assembly of the stamped blade and the blade head.

[0016] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art: In existing shaving systems, the moving blade not only contacts the cutting edge but also the entire back surface during the cutting process. This causes the shaving mesh to heat up during the cutting motion, affecting the skin feel. Furthermore, because the cutting edge is flush with the back surface, the cutting relies entirely on the moving blade. If the hair is coarse, this not only results in a sharp cutting edge but also causes pulling pain and leaves stubble, severely compromising the shaving experience. Additionally, the smooth front surface weakens the connection between the two mesh openings, requiring optimization of the mesh edges for better contact. Otherwise, it hinders hair guidance during skin contact and increases the risk of scratches or abrasions. This invention, however, features a holistic design based on a stamped shaving mesh structure, cleverly... This invention cleverly addresses the shortcomings and defects of existing technologies by employing a stamped blade mesh. The edges of the mesh formed by stamping are rounded to guide the hair in. Then, the cutting surface formed by the protruding blade on the back side, which matches the moving blade, shears and removes the hair through the relative movement of the blade and the cutting surface. Therefore, this invention, on the one hand, improves the hair guide rate of the skin-contact surface by using rounded edges formed by stamping, enhancing the safety and tactile comfort of the skin-contact surface, while further reducing stubble residue. On the other hand, the blade layout on the back side and the shearing action between the moving blade and the blade surface reduce the contact area between the blade mesh and the moving blade, lowering the temperature rise of the blade mesh and improving the tactile feel. Furthermore, the sharp shearing action of the blade and the moving blade improves the efficiency and quality of hair removal. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0024] like Figures 1 to 5 As shown, the stamped blade mesh of this embodiment includes a blade mesh body 1 with mesh holes 10. The front side of the blade mesh body is a skin-feel contact surface 1a. The mesh holes 10 are stamped from the front side to the back side. The skin-feel contact surface 1a is formed by stamping concavity and the edges of each mesh hole 10 are rounded. The edges of the mesh holes 10 punched from the back side form mesh hole cutting portions 1b that protrude from the back side. The mesh hole cutting portions 1b are aligned away from the cutting edge surface 10b on the front side to form a cutting surface that matches the moving blade.

[0025] Specifically, the connecting portions between two adjacent mesh openings 10 are kept flush to form a skin-feeling contact surface 1a. This flush fit improves tactile comfort. The cutting surface is parallel to the skin-feeling contact surface 1a. This parallelism prevents unevenness in the tactile contact surface caused by the mesh cutting edge engaging with the moving blade.

[0026] In some specific embodiments, the stamped mesh openings are arranged in an array. The mesh openings 10, based on the array layout, allow for relatively uniform introduction of hair. The array includes a first array and a second array, wherein the mesh openings 10 of the first and second arrays are staggered at intervals. This relatively staggered arrangement of multiple arrays results in a denser mesh distribution, which is more conducive to the introduction of hair.

[0027] In this example, the row spacing and column spacing of the first and second arrays are equal. The center-to-center distance between any two adjacent rows of mesh 10 in the row spacing direction is L1, and the center-to-center distance between any two meshes in each row in the column spacing direction is L2, where L1 > L2. Further constraints on the row and column spacing of the arrays allow for a more compact mesh layout, enabling the introduction of hairs into the mesh from multiple angles.

[0028] In some specific embodiments, the length of the mesh cutting edge 1b is less than the thickness of the blade body 1. This avoids the formation of excessively long protrusions during stamping, which not only affects the performance of the mesh cutting edge itself but also directly impacts the shearing effect achieved through the interaction of the moving blades.

[0029] In this example, the length of the mesh blade 1b is 1 / 5 to 1 / 3 of the thickness of the foil body 1. In some specific embodiments, the length of the mesh blade is 3 / 11 of the thickness of the foil body. Based on the appropriate length and thickness matching, the best cutting effect is provided. At the same time, the R-angle of the stamped concave shape and the rounded corner transition of each mesh 10 is ≤10μm. Due to the limitation of the R-angle, not only can the skin be brought close to or inserted into the mesh to form a cut at the root of the hair, but the rounded corner can also guide the hair into the mesh more smoothly (higher guide rate). In addition, since the R-angle is formed during stamping, the deformation caused by stamping can also be fully utilized to improve the hair entry and shaving quality of the foil.

[0030] In addition, assembly holes 11 are provided on opposite sides of the blade body 1. The assembly holes 11 are provided to facilitate the assembly of the stamped blade and the blade head.

[0031] In summary, by employing this stamped blade mesh, the edges of the mesh formed by stamping are all rounded to guide the hair in. Then, the cutting surface formed by the protruding blade on the back side, which matches the moving blade, shears and removes the hair through the relative movement of the moving blade and the cutting surface. Therefore, this invention, on the one hand, improves the hair removal rate of the skin-contact surface by using the rounded edges of the stamped mesh, enhancing the safety and tactile comfort of the skin-contact surface, while further reducing stubble residue. On the other hand, the blade layout on the back side and the shearing action between the moving blade and the blade surface reduce the contact area between the blade mesh and the moving blade, lowering the temperature rise of the blade mesh and improving the tactile feel. Furthermore, the sharp shearing effect achieved by the cutting edge and blade improves the efficiency and quality of hair removal; thirdly, the length of the mesh cutting edge is less than the thickness of the mesh body, avoiding excessive protrusion caused by stamping, which not only affects the performance of the mesh cutting edge itself but also directly affects the shearing effect formed by the moving blade. In some specific embodiments, the length of the mesh cutting edge is 3 / 11 of the thickness of the mesh body. Based on the appropriate length and thickness matching, the best shearing effect is provided; fourthly, the rounded corner R angle used is ≤10μm. Based on the limitation of the rounded corner R angle, not only can the skin be brought close to or inserted into the mesh to form a shear at the root of the hair, but the rounded corner can also more smoothly guide the hair into the mesh. (High hair induction rate); furthermore, its R-angle is based on the stamping process, thus fully utilizing the deformation caused by stamping to improve the hair intake and shaving quality of the foil; fifthly, the connecting parts between two adjacent mesh openings are kept flush to form a skin-feeling contact surface, and the skin fit formed by the flush surface improves the tactile comfort; sixthly, the cutting surface is parallel to the skin-feeling contact surface, and the parallelism avoids unevenness of the tactile contact surface caused by the mesh cutting edge and the moving blade; seventhly, the mesh openings are arranged in an array to guide hair relatively evenly, and the array includes a first array and a second array, wherein the mesh openings of the first array and the second array are staggered, based on multiple arrays. The relatively staggered layout makes the mesh distribution denser, which is more conducive to the introduction of hair. In addition, the row spacing of the first array and the column spacing of the second array are equal, the center distance formed by the mesh of each two adjacent rows in the row spacing direction is L1, and the center distance between two meshes in each row in the column spacing direction is L2, where L1>L2. Based on the further limitation of the row spacing and column spacing of the array, the mesh layout is made more compact, thereby introducing hair into the mesh from multiple angles. In the eighth aspect, assembly holes are also provided on opposite sides of the blade mesh body. Here, the assembly holes are set to facilitate the assembly of the stamping blade mesh and the blade head.

[0032] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
