Description

Technical Field

[0001] This utility model relates to a hair trimming component, and more specifically to a hair trimming scissor net, which is mainly used in the field of personal care tools such as razors and hair clippers. Background Technology

[0002] The foils used in reciprocating shavers or hair clippers are generally U-shaped. The moving blades are installed in the moving blade holder and located below the foil, fitting snugly against it. As the moving blade holder swings back and forth with the drive mechanism, the moving blades can cut off hairs such as beards that extend into the U-shaped foil.

[0003] However, when the moving blade swings back and forth along the blade mesh, the two ends of the moving blade will lift up during the swing process, causing the two ends of the moving blade to hit the two ends of the blade mesh. Therefore, after a period of use, the two ends of the blade mesh are very prone to breakage, which reduces the service life of the blade mesh. Utility Model Content

[0004] To solve the above technical problems, this utility model provides a trimming scissor mesh. This scissor mesh not only improves the trimming effect but also effectively strengthens the strength of its two ends, preventing breakage when the moving blades impact, and extending the service life of the scissor mesh.

The intersection point of the +X axis and the -X axis with the Y-axis is the origin o. The substrate is bent into a U-shape along the +X axis and the -X axis. The entry holes penetrate the substrate with the origin o as the center, and are arranged alternately along the Y-axis, +X-axis and -X-axis to form a number of entry holes on the substrate; The substrate has an outer surface that comes into contact with the skin and an inner surface that mates with the moving blade, with an integral isolation layer formed on the inner surface.

[0029] The beneficial effect of this invention is that the spacing L between adjacent feed holes arranged in the substrate, at least in the +X axis and / or -X axis directions, is different, and the spacing L between adjacent feed holes increases with the distance from the origin o. Since the change in spacing L increases with the distance from the origin o, it means that the spacing L between adjacent feed holes farther from the origin o becomes wider and wider, and the spacing between adjacent feed holes closer to the two ends of the substrate is even wider. This allows for a larger force-bearing area closer to the edges of the substrate, greatly improving the working strength of the two ends of the substrate. When the moving blades impact the cutting mesh due to tilting during the oscillating cutting process, it effectively prevents the ends of the cutting mesh from breaking due to the impact of the moving blades, ensuring the working performance of the cutting mesh and extending its service life.

[0037] The following is in conjunction with the appendix Figures 1-7 The embodiments of this utility model are further described below:

[0038] In existing reciprocating shavers or hair trimmers, the moving blades oscillate along the foil, causing their ends to lift up during the oscillation. This results in the moving blades' ends striking the ends of the foil, making the foil prone to breakage after a period of use, thus reducing its lifespan. To address this technical problem of the foil's easy breakage during use, this invention proposes the following implementation methods:

[0039] Example 1:

[0040] like Figure 1 As shown, the trimming shear mesh includes a substrate 1. During production, the substrate 1 is mostly cut into a square shape according to actual needs. The substrate 1 has a Y-axis at the center of its length direction, and +X and -X axes on both sides of the Y-axis in its width direction. The intersection point of the +X and -X axes with the Y-axis is the origin o. The substrate 1 is bent into a U-shape along the +X and -X axes. The moving blade is semi-circular (not shown in the figure) and always keeps in contact with the inner surface of the U-shaped blade mesh.

[0041] The entry holes 2 penetrate the substrate 1 with the origin o as the center, and are arranged alternately along the Y-axis, +X-axis and -X-axis to form a number of horizontal and vertical entry holes 2 on the substrate 1. The entry holes 2 are used to capture hair such as beards. When the hair such as beards enters the blade net, it can be cut by the moving blade (not shown in the figure) located below the blade net, so as to achieve the purpose of trimming hair such as beards.

[0042] To improve the working strength of the blade mesh and prevent it from breaking due to impact from the blades at both ends, the spacing L between adjacent entry holes 2 in the substrate 1, at least in the +X axis and / or -X axis directions, is different, and the spacing L between adjacent entry holes 2 increases with the distance from the origin o. For example... Figure 1 As shown, taking the origin o in substrate 1 as a reference (which can also be understood as taking the Y-axis as a reference), among a number of entry holes 2 arranged linearly along the +X axis, the spacing L between any two adjacent entry holes 2 is different. To facilitate the understanding of the key improvements of this technical solution by relevant personnel, in Figure 1Two points, L1 and L2, were randomly selected as auxiliary references. It is evident that L2 > L1 > L. Since the spacing L increases with the distance from the origin o, it means that the spacing L between adjacent feed holes 2 further away from the origin o becomes wider and wider. The spacing between adjacent feed holes 2 is larger closer to the edges of the substrate 1. This increases the stress area of ​​the substrate 1 closer to the edges, greatly improving the working strength of the edges of the substrate 1. When the moving blades impact the blade mesh due to tilting during the oscillating cutting process, it can effectively prevent the blade mesh from breaking due to the impact of the moving blades, ensuring the working performance of the blade mesh and extending its service life.

[0043] Similarly, the spacing L between several entry holes 2 set in the -X axis direction of the substrate 1 and the spacing L between entry holes 2 set in the +X axis direction are mirror-symmetrical about the origin o. The spacing L between adjacent entry holes 2 in symmetrical positions is the same.

[0044] In theory, not setting the entry holes 2 at the positions in the blade mesh that are easily hit by the blade can improve the working strength of the blade mesh and prevent it from breaking. However, not setting the entry holes 2 reduces the surface utilization rate of the blade mesh and reduces the entry area of ​​the blade mesh. Therefore, this embodiment improves the working strength of the blade mesh by increasing the spacing L between adjacent entry holes 2 without reducing the entry area of ​​the blade mesh.

[0045] In actual production, the spacing L between several linearly arranged fiber entry holes 2 in the +X and -X axis directions of the substrate 1 can be set to different values. For example, the spacing L between several fiber entry holes 2 in the -X axis direction of the substrate 1 can be smaller than the spacing L between several linearly arranged fiber entry holes 2 in the +X axis direction. In this case, the arrangement density of several fiber entry holes 2 in the -X axis direction of the substrate 1 will be greater than the arrangement density of fiber entry holes 2 in the X axis direction. Although this can increase the fiber entry efficiency in the -X axis direction of the substrate 1, it relatively reduces the workload in the -X axis direction of the substrate 1. Therefore, it is a preferred embodiment to use symmetrically arranged fiber entry holes 2 with the same spacing in the +X and -X axis directions of the substrate 1. Please note that the same spacing mentioned here means that the spacing of fiber entry holes 2 at the same symmetrical position in the +X and -X axis directions of the substrate 1 is the same, not that the spacing of fiber entry holes 2 linearly arranged on one side of the origin o in the substrate 1 is the same.

[0046] To maximize the working strength of the blade mesh, the spacing L between adjacent feed holes 2, located further from the origin o along the +X and -X axes of the substrate 1, is greater than the radius R of the feed holes 2. Since the feed holes 2 are linearly arranged along the +X and -X axes of the substrate 1, the further the feed holes 2 are from the origin o, the larger the spacing L between adjacent feed holes 2 becomes (forming spacing L1 or L2). When the spacing L1 or L2 is greater than the radius R of the feed holes 2, the stress-bearing area at both ends of the blade mesh is correspondingly increased, which greatly enhances the working strength at the edges of the blade mesh, thereby minimizing the risk of breakage due to impact from the blades and extending the service life of the blade mesh.

[0047] Example 2:

[0048] Unlike the method used in Example 1, which controls the spacing L between the feed holes 2 to improve the working strength of the cutting edge, this example achieves the purpose of improving the working strength of the cutting edge by controlling the size of the feed holes 2. Specifically:

[0049] like Figure 2 As shown, the trimming shear mesh includes a substrate 1. During production, the substrate 1 is mostly cut into a square shape according to actual needs. The substrate 1 has a Y-axis at the center of its length direction, and +X and -X axes on both sides of the Y-axis in its width direction. The intersection point of the +X and -X axes with the Y-axis is the origin o. The substrate 1 is bent into a U-shape along the +X and -X axes. The moving blade is semi-circular (not shown in the figure) and always keeps in contact with the inner surface of the U-shaped blade mesh.

[0050] The entry holes 2 penetrate the substrate 1 with the origin o as the center, and are arranged alternately along the Y-axis, +X-axis and -X-axis to form a number of horizontal and vertical entry holes 2 on the substrate 1. The entry holes 2 are used to capture hair such as beards. When the hair such as beards enters the blade net, it can be cut by the passive blade (not shown in the figure) to achieve the purpose of trimming hair such as beards.

[0051] To improve the working strength of the blade mesh and prevent it from breaking due to impact from the blades at both ends, the substrate 1 has several entry holes 2 with different radii R arranged in at least the +X axis and / or -X axis directions, and the radius R of the entry holes 2 decreases as the distance from the origin o increases. For example... Figure 2 As shown, taking the origin o in substrate 1 as a reference (which can also be understood as taking the Y-axis as a reference), among a number of entry holes 2 arranged linearly along the +X axis, the radii R of any two adjacent entry holes 2 are different. To facilitate understanding of the key improvements of this technical solution by relevant personnel, in Figure 2Two entry holes 2 were randomly selected as auxiliary references, namely R1 and R2. It can be clearly seen that R2 > R1 > R. Since the radius R of the entry hole 2 decreases with the distance from the origin o, it means that the radius R of the entry hole 2 further away from the origin o becomes smaller and smaller. The radius R of the entry hole 2 is smaller closer to the two ends of the substrate 1. This relatively widens the distance L between adjacent entry holes 2 in the X and Y axis directions, significantly increasing the force-bearing area of ​​the edge region of the substrate 1. This greatly improves the working strength of the two ends of the substrate 1. When the two ends of the moving blade collide with the blade mesh due to the lifting during the oscillating cutting process, it can effectively prevent the two ends of the blade mesh from breaking due to the impact of the moving blade, ensuring the working performance of the blade mesh and extending its service life.

[0052] Similarly, the radius R of several entry holes 2 set in the -X axis direction of the substrate 1 is mirror-symmetrical with respect to the origin o, and the radius R of the entry holes 2 set in the +X axis direction is the same.

[0053] In actual production, the radii R of the entry holes 2 in the substrate 1 along the +X axis and -X axis may be the same or different. The entry holes 2 preferably use the same radius R. That is, the entry holes 2 arranged linearly in the +X axis direction and the entry holes 2 arranged linearly in the -X axis direction are symmetrically arranged with the origin as the reference. The radii R of the entry holes 2 at the symmetrical positions are the same. This can make the overall working strength of the blade mesh more balanced and the working stability of the blade mesh higher.

[0054] However, considering the efficiency of burr entry in the blade mesh, the burr entry holes 2 in the substrate 1 along the +X and -X axes can have different radii R. For example, the radius R of the burr entry holes 2 linearly arranged along the -X axis can be smaller than the radius R of the corresponding burr entry holes 2 linearly arranged along the +X axis. This increases the density of burr entry holes 2 in the -X axis direction of the substrate 1, thus improving the burr entry efficiency. However, using different radii of burr entry holes 2 in the +X and -X axis directions on both sides of the origin o of the substrate 1 will cause inconsistent working strength at both ends of the blade mesh, making one end of the blade mesh more susceptible to breakage due to impact from the blade. Therefore, using the same radius of burr entry holes 2 is the preferred implementation.

[0055] In Embodiment 1, a technical solution was disclosed to improve the working strength at both ends of the blade mesh by increasing the spacing L between adjacent entry holes 2 in the substrate 1. In this embodiment, different spacings L can also be superimposed with different radii R of entry holes 2. Even if the spacing L between adjacent entry holes 2 in the +X and -X axis directions of the substrate 1 is the same or different, the working strength at both ends of the blade mesh can still be increased. Preferably, the spacing L is the same, meaning the spacing L between adjacent entry holes 2 in the +X and -X axis directions of the substrate 1 is the same, which can balance the entry efficiency and working strength of the blade mesh. However, if different spacings are used between adjacent entry holes 2 in the +X and -X axis directions of the substrate 1, it will not only reduce the entry efficiency on one side of the origin o in the substrate 1, but also make the working strength on both sides of the origin o in the substrate 1 inconsistent, affecting the working stability of the blade mesh. Therefore, the use of the same spacing L is the preferred implementation method in this embodiment.

[0056] Example 3:

[0057] Inspired by embodiments 1 and 2 above, this embodiment combines the technical solution of forming different spacing L between adjacent entry holes 2 disclosed in embodiment 1 with the technical solution of different entry hole radii R disclosed in embodiment 2, specifically as follows:

[0058] like Figure 3 As shown, the trimming shear mesh includes a substrate 1. During production, the substrate 1 is mostly cut into a square shape according to actual needs. The substrate 1 has a Y-axis at the center of its length direction, and +X and -X axes on both sides of the Y-axis in its width direction. The intersection point of the +X and -X axes with the Y-axis is the origin o. The substrate 1 is bent into a U-shape along the +X and -X axes. The moving blade is semi-circular (not shown in the figure) and always keeps in contact with the inner surface of the U-shaped blade mesh.

[0059] The entry holes 2 penetrate the substrate 1 with the origin o as the center, and are arranged alternately along the Y-axis, +X-axis and -X-axis to form a number of horizontal and vertical entry holes 2 on the substrate 1. The entry holes 2 are used to capture hair such as beards. When the hair such as beards enters the blade net, it can be cut by the passive blade (not shown in the figure) to achieve the purpose of trimming hair such as beards.

[0060] To improve the working strength of the blade mesh and prevent it from breaking due to impact from the blades at both ends, the spacing L and radius R between adjacent entry holes 2 arranged in the substrate 1, at least in the +X axis and / or -X axis directions, are different. Furthermore, as the distance from the origin o increases, the spacing L between adjacent entry holes 2 becomes larger and the radius R of adjacent entry holes 2 becomes smaller. For example... Figure 3As shown, taking the origin o in substrate 1 as a reference (which can also be understood as taking the Y-axis as a reference), among a number of entry holes 2 arranged linearly along the +X axis, the spacing L between any two adjacent entry holes 2 is different. To facilitate the understanding of the key improvements of this technical solution by relevant personnel, in Figure 3 Two points, L1 and L2, were randomly selected as auxiliary references. It is evident that L2 > L1 > L. Since the spacing L increases with the distance from the origin o, it means that the spacing L between adjacent entry holes 2 further away from the origin o becomes wider and wider. The spacing between adjacent entry holes 2 is larger closer to the two ends of the substrate 1. This allows the force-bearing area of ​​the substrate 1 to be larger closer to the edge, which can greatly improve the working strength of the two ends of the substrate 1.

[0061] Secondly Figure 3 The document also demonstrates several entry holes 2 arranged linearly along the +X axis, with the origin o in substrate 1 as the reference (which can also be understood as the Y-axis as the reference). The radii R of any two adjacent entry holes 2 are different. To facilitate understanding of the key improvements in this technical solution, [further details are provided]. Figure 3 Two entry holes 2 were randomly selected as auxiliary references, namely R1 and R2. It can be clearly seen that R2 > R1 > R. Since the radius R of the entry hole 2 decreases with the distance from the origin o, it means that the radius R of the entry hole 2 becomes smaller and smaller further away from the origin o. The radius R of the entry hole 2 is smaller closer to the two ends of the substrate 1. This relatively widens the distance L between adjacent entry holes 2 in the X and Y axis directions, and significantly increases the force-bearing area in the edge region of the substrate 1.

[0062] By combining the two technical solutions mentioned above to increase the working strength of both ends of the substrate 1, the working strength of the edges at both ends of the substrate 1 can be greatly improved. When the moving blade ends collide with the blade mesh due to the lifting during the swing cutting process, the blade mesh ends can be effectively prevented from breaking due to the impact of the moving blade, thus ensuring the working performance of the blade mesh and extending its service life.

[0063] In actual production, the radii R of the entry holes 2 in the substrate 1 along the +X axis and -X axis may be the same or different. The entry holes 2 preferably use the same radius R. That is, the entry holes 2 arranged linearly in the +X axis direction and the entry holes 2 arranged linearly in the -X axis direction are symmetrically arranged with the origin as the reference. The radius R of the entry holes 2 at the symmetrical position is the same. This can make the overall working strength of the blade mesh more balanced and the working stability of the blade mesh higher.

[0064] However, considering the efficiency of burr entry in the blade mesh, the burr entry holes 2 in the substrate 1 along the +X and -X axes can have different radii R. For example, the radius R of the burr entry holes 2 linearly arranged along the -X axis can be smaller than the radius R of the corresponding burr entry holes 2 linearly arranged along the +X axis. This increases the density of burr entry holes 2 in the -X axis direction of the substrate 1, thus improving the burr entry efficiency. However, using different radii of burr entry holes 2 in the +X and -X axis directions on both sides of the origin o of the substrate 1 will cause inconsistent working strength at both ends of the blade mesh, making one end of the blade mesh more susceptible to breakage due to impact from the blade. Therefore, using the same radius of burr entry holes 2 is the preferred implementation.

[0065] In Embodiment 1, a technical solution was disclosed to improve the working strength at both ends of the blade mesh by increasing the spacing L between adjacent entry holes 2 in the substrate 1. In this embodiment, different spacings L can also be superimposed with different radii R of entry holes 2. Even if the spacing L between adjacent entry holes 2 in the +X and -X axis directions of the substrate 1 is the same or different, the working strength at both ends of the blade mesh can still be increased. Preferably, the spacing L is the same, meaning the spacing L between adjacent entry holes 2 in the +X and -X axis directions of the substrate 1 is the same, which can balance the entry efficiency and working strength of the blade mesh. However, if different spacings are used between adjacent entry holes 2 in the +X and -X axis directions of the substrate 1, it will not only reduce the entry efficiency on one side of the origin o in the substrate 1, but also cause the working strength on both sides of the origin o in the substrate 1 to be inconsistent, affecting the working stability of the blade mesh. Therefore, the use of the same spacing L is the preferred implementation method in this embodiment.

[0066] Example 4:

[0067] like Figure 4-7 As shown, the trimming scissor net includes a base plate 1. During production, the base plate 1 is mostly cut into a square shape according to actual needs. A Y-axis is located at the center of the base plate 1 along its length. A +X-axis and a -X-axis are located on either side of the Y-axis along the width of the base plate 1. The intersection point of the +X-axis and -X-axis with the Y-axis is the origin o. Hair inlets 2 penetrate the base plate 1 with the origin o as the center, and are arranged alternately along the Y-axis, +X-axis, and -X-axis, forming several horizontally and vertically arranged hair inlets 2 on the base plate 1. The hair inlets 2 are used to capture beard hairs, etc. When beard hairs enter the scissor net, they are cut by the moving blades (not shown in the figure), achieving the purpose of trimming beard hairs. The base plate 1 is bent into a U-shape along the +X-axis and -X-axis, and the moving blades are semi-circular (not shown in the figure), always maintaining contact with the inner surface of the U-shaped scissor net.

[0068] To enhance the working strength of the blade mesh and prevent it from cracking due to impact from the blades at both ends, a first thickness D1 is formed with the origin o in substrate 1 as the reference, while a second thickness D2 is formed at the edges of substrate 1 along the +X and -X axes. Furthermore, the first thickness D1 and the second thickness D2 are different. In actual production, the first thickness D1 is smaller than the second thickness D2, and the thickness gradually increases from the origin o to the second thickness D2.

[0069] like Figure 4-6 As shown, the first thickness D1 at the origin o of substrate 1 is less than the second thickness D2 at both ends of substrate 1. During use, the blade is curved into a U-shape. Basically, the apex of the curve contacts the skin and the blade cuts hairs such as beards. When the first thickness D1 at the origin o of substrate 1 is less than the second thickness D2 at both ends of substrate 1, the hair roots remaining on the skin surface after the beards and other hairs are cut are shorter, which effectively improves the trimming effect of the blade.

[0070] like Figure 4 As shown, in the actual production process, the first thickness D1 formed at the origin o of substrate 1 can be formed by uniformly cutting from the two planes of substrate 1 towards the origin o, or it can be formed as follows: Figure 5 As shown in Figure 6, the cutting can be performed from either of the two planes of the substrate 1. The specific method depends on the actual available process conditions or production facilities. This embodiment does not impose further restrictions.

[0071] Secondly, since the second thickness D2 at both ends of the substrate 1 is thicker than the first thickness D1, the working strength of the two ends of the substrate 1 is higher. When the two ends of the moving blade collide with the blade mesh due to the lifting during the swing cutting process, it can effectively prevent the two ends of the blade mesh from being broken by the impact of the moving blade, thus ensuring the working performance of the blade mesh and extending its service life.

[0072] To improve the overall working strength and stability of the cutter head, a third thickness D3 is formed on both sides of the substrate 1, with the Y-axis as the reference. The first thickness D1 is smaller than the third thickness D3, and the thickness gradually increases from the origin o to the third thickness D3. Existing cutter heads are mostly curved into a U-shape, and assembly utilizes the two side walls of the U-shape. Since the thickness of the side walls of existing U-shaped cutter heads is the same as the thickness of the middle curved section, the installation firmness is relatively low due to the thickness of the side walls. For example... Figure 7 As shown, by adjusting the material thickness at the edge of the substrate 1 along the Y-axis, a third thickness D3 greater than the first thickness D1 is formed. This not only improves the hair trimming effect of the blade mesh by utilizing the thinner first thickness D1, but also significantly enhances the working strength of the side walls on both sides of the U-shaped blade mesh. When the blade mesh is installed and fixed with the stationary blade holder (not shown in the figure), the installation firmness of the blade mesh can be effectively improved.

[0073] In actual production, the second thickness D2 and the third thickness D3 in substrate 1 can be the same or different, preferably the same thickness. If different thicknesses are used, it will affect the overall working strength of the blade mesh and also complicate the production process, reducing production efficiency. Therefore, using the same thickness is the preferred implementation method in this embodiment. Secondly, the thickness of the edges in the Y-axis direction on both sides of the origin o in substrate 1 can be the same or different, as long as the installation firmness of the blade mesh can be guaranteed. This embodiment does not make further limitations.

[0074] To balance the trimming effect and work intensity of the blade mesh, the first thickness D1 in the substrate 1 is greater than or equal to half of the second thickness D2 or the third thickness D3. In actual production, the second thickness D2 and the third thickness D3 are the same, which is also the initial material thickness of the substrate 1. The first thickness D1 is set to be less than the second thickness D2 or the third thickness D3. When the substrate 1 is bent into a U-shape, the first thickness D1 is at the apex of the bend. During use, it directly contacts the skin and works with the moving blade to cut hairs such as beards that extend into the blade mesh. When the first thickness D1 becomes thinner, the hair roots of the beards and other hairs cut by the moving blade are shortened accordingly, improving the hair trimming effect of the blade mesh.

[0075] The thickness of the existing substrate 1 is mostly less than 0.5mm, meaning that the second thickness D2 or the third thickness D3 is also less than 0.5mm. Setting the first thickness D1 in the substrate 1 to be greater than or equal to half of the second thickness D2 or the third thickness D3 ensures the hair trimming effect of the blade mesh while maximizing its working strength, preventing it from being torn by the blade due to an excessively thin first thickness D1, thus guaranteeing the performance and lifespan of the blade mesh. Alternatively, the first thickness D1 in the substrate 1 could be set to be less than half of the second thickness D2 or the third thickness D3. However, since the blade mesh material itself is thin (mostly less than 0.5mm), setting the first thickness D1 to be less than half of the second thickness D2, while improving the hair trimming effect, would correspondingly reduce the working strength of the blade mesh at its bends, making it more susceptible to tearing from the high-frequency reciprocating cutting of the blade. Therefore, setting the first thickness D1 to half or more of the second thickness D2 or the third thickness D3 is the preferred embodiment of this practice.

[0076] This embodiment mainly improves the working strength of the cutting mesh by using different thicknesses of the substrate 1. Embodiment 1 discloses improving the working strength of both ends of the cutting mesh by increasing the spacing L between adjacent feed holes 2. In actual production, the technical solution of varying the spacing L between adjacent feed holes 2 disclosed in Embodiment 1 can also be combined with this embodiment. That is, the spacing L between adjacent feed holes 2 arranged in the substrate 1 at least in the +X axis and / or -X axis direction is different, and the spacing L between adjacent feed holes 2 increases with the distance from the origin o. This can maximize the working strength of both ends of the cutting mesh. When the moving blade ends collide with the cutting mesh due to tilting during the swing cutting process, it can effectively prevent the ends of the cutting mesh from breaking due to the impact of the moving blade, ensuring the working performance of the cutting mesh and extending the service life of the cutting mesh.

[0077] This embodiment mainly improves the working strength of the cutting mesh by using different thicknesses of the substrate 1. Embodiment 1 discloses improving the working strength of both ends of the cutting mesh by increasing the spacing L between adjacent entry holes 2. In actual production, the technical solution of gradually reducing the radius R of adjacent entry holes 2 disclosed in Embodiment 2 can also be combined with this embodiment. That is, the radius R of several entry holes 2 arranged in the substrate 1 in at least the +X axis and / or -X axis directions is different, and the radius R of entry holes 2 becomes smaller as the distance from the origin o increases. By controlling the gradual reduction of the radius R of the linearly arranged entry holes 2, the spacing L between adjacent entry holes 2 in the Y axis direction of the substrate 1 is relatively increased. This can also effectively improve the working strength of both ends of the cutting mesh. When the two ends of the moving blade hit the cutting mesh due to the lifting during the swing cutting process, it can prevent the two ends of the cutting mesh from breaking due to the impact of the moving blade, ensuring the working performance of the cutting mesh and extending the service life of the cutting mesh.

[0078] Example 5:

[0079] like Figure 7 As shown, the substrate 1 is cut into a square shape according to actual needs during production. The substrate 1 has a Y-axis at the center of its length direction, and a +X axis and a -X axis on both sides of the Y-axis in the width direction of the substrate 1. The intersection point of the +X axis and the -X axis with the Y-axis is the origin o. The substrate 1 is bent into a U-shape along the +X axis and the -X axis. The moving blade is semi-circular (not shown in the figure) and always keeps in contact with the inner surface of the U-shaped blade mesh.

[0080] The entry holes 2 penetrate the substrate 1 with the origin o as the center, and are arranged alternately along the Y-axis, +X-axis and -X-axis to form a number of horizontal and vertical entry holes 2 on the substrate 1. The entry holes 2 are used to capture hair such as beards. When the hair such as beards enters the blade net, it can be cut by the blade (not shown in the figure) to achieve the purpose of trimming hair such as beards.

[0081] To enhance the working strength of the blade mesh and prevent it from breaking due to impact from the moving blades at both ends, the substrate 1 has an outer surface that contacts the skin and an inner surface that mates with the moving blades. An integral isolation layer 3 is formed on the inner surface. By forming an integral isolation layer 3 on the inner surface of the blade mesh, the isolation layer 3 effectively acts as a buffer when the moving blades impact the blade mesh during oscillating cutting, thus preventing the blade mesh from breaking due to impact, ensuring the working performance of the blade mesh, and extending its service life.

[0082] Furthermore, since existing blade mesh materials are primarily made of electroformed nickel through metal electrodeposition, their thickness is relatively thin, mostly around 0.20mm. While they possess good corrosion resistance, their strength is relatively low. As the base material for the blade mesh, after a period of use, the cutting edges of the entry holes 2 will curl or chip, resulting in a significant decrease in sharpness. To avoid this, users need to add lubricating oil between the moving blade and the blade mesh each time they use it to reduce wear; however, adding lubricating oil before each use increases the cumbersomeness of use and results in a relatively poor user experience. Therefore, by adding an isolation layer 3 to the inner surface of the blade mesh, lubricating oil is not required when the moving blade reciprocates along the inner surface of the blade mesh. This also effectively reduces wear on the blade mesh, protects it from curling or chipping of the cutting edges of the entry holes 2, improves the cutting sharpness of the blade mesh, and effectively extends the service life of both the blade mesh and the cutting edges of the entry holes 2.

[0083] In actual production, the isolation layer 3 is attached to the inner surface of the blade mesh using an electroplating process. The thickness of the isolation layer 3 is less than or equal to 5μm, preferably 2μm. To improve the service life of the blade mesh, the isolation layer 3 is formed by electroplating any one of the following high-hardness materials: diamond-like carbon, graphene, titanium nitride, tool titanium, tungsten carbide, chromium plating, nickel-cobalt (Ni-Co) alloy, nickel-phosphorus (Ni-P) alloy, boron carbide, and silicon carbide, so that the hardness of the isolation layer 3 is greater than or equal to 500HV. By increasing the hardness of the isolation layer 3, the cutting edge of the entry hole 2 in the blade mesh can be effectively protected, ensuring the cutting sharpness of the blade mesh. Furthermore, it can prevent the passive blade from being broken by the blade when the moving blade ends impact the blade mesh due to warping during the oscillating cutting process. Since the electroplating process or electroplating material is a mature existing technology, it will not be described in detail in this embodiment.

[0084] To further enhance the working strength of the cutting mesh, the spacing L between adjacent feed holes 2 arranged in the substrate 1, at least in the +X axis and / or -X axis directions, is different, and the spacing L between adjacent feed holes 2 increases with the distance from the origin o. Example 1 describes a method to improve the overall working strength of the cutting mesh by controlling the spacing L between the feed holes 2. Combining this with the technical solution of setting an isolation layer 3 can effectively improve the overall working strength of the cutting mesh, preventing the passive blade from breaking when the moving blades impact the mesh due to their tilting during the oscillating cutting process, thus providing a double protective effect.

[0085] To maximize the working strength of the cutting mesh, the substrate 1 contains several entry holes 2 with varying radii R, arranged along at least the +X and / or -X axes. The radius R of the entry holes 2 decreases with increasing distance from the origin o. Example 2 describes a method to enhance the overall working strength of the cutting mesh by controlling and reducing the radius of the entry holes 2. Combining this with the technique of setting an isolation layer 3 maximizes the overall working strength of the cutting mesh, preventing it from being broken by the passive blade when the moving blades impact the mesh during oscillating cutting. This provides triple protection for the cutting mesh.

[0086] To achieve optimal protection for the blade mesh and prevent it from being punctured by the passive blade when the moving blades at both ends collide with the mesh during oscillating cutting, a first thickness D1 is formed in the substrate 1 with the origin o as the reference, and a second thickness D2 is formed at the edges of the substrate 1 along the +X and -X axes. The first thickness D1 is smaller than the second thickness D2, and the thickness gradually increases from the origin o to the second thickness D2. Example 4 describes improving the overall working strength of the blade mesh by varying the thickness of the substrate 1. Combining this with the technical solution of setting the isolation layer 3 effectively strengthens and enhances the overall working performance of the blade mesh, maximizing the prevention of puncture by the passive blade when the moving blades at both ends collide with the mesh during oscillating cutting, thus providing quadruple protection for the blade mesh.

[0087] To improve the overall working strength and stability of the cutter head, a third thickness D3 is formed on both sides of the substrate 1, with the Y-axis as the reference. The first thickness D1 is smaller than the third thickness D3, and the thickness gradually increases from the origin o to the third thickness D3. Existing cutter heads are mostly curved into a U-shape, and assembly utilizes the two side walls of the U-shape. Since the thickness of the side walls of existing U-shaped cutter heads is the same as the thickness of the middle curved section, the installation firmness is relatively low due to the thickness of the side walls. For example... Figure 7As shown, by adjusting the material thickness at the edge of the substrate 1 along the Y-axis, a third thickness D3 greater than the first thickness D1 is formed. This not only improves the hair trimming effect of the blade mesh by utilizing the thinner first thickness D1, but also significantly enhances the working strength of the side walls on both sides of the U-shaped blade mesh. When the blade mesh is installed and fixed with the stationary blade holder, the installation firmness of the blade mesh can be effectively improved.

[0088] The above embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
