Description

Technical Field

[0001] This invention relates to the field of blade manufacturing technology, and more particularly to a razor. Background Technology

[0002] Existing razors include a stationary blade and a moving blade. The stationary blade has a stationary cutting section that forms stationary blade teeth. The moving blade can move relative to the stationary blade and has two moving blades connected as a whole. Both moving blades have moving blade teeth at the same end, forming moving blade teeth. The two moving blade teeth together form a moving blade cutting section that cooperates with the stationary blade cutting section.

[0003] The static blade is a comb-shaped outer blade. Hair enters directly from the guide groove in the middle of the top of the comb-shaped outer blade, achieving hair introduction and capture. However, each guide groove on the comb-shaped outer blade extends along its width, which prevents the hair from moving along the length of the blade, resulting in a relatively poor shaving effect. Summary of the Invention

[0004] The main objective of this invention is to provide a razor that enhances the ability to guide and capture hair, thereby improving the shaving effect.

[0005] To achieve the above objectives, the present invention provides a razor comprising a blade body having a faceplate that contacts the skin and a side plate disposed on at least one side of the faceplate and connected to the faceplate. At least one edge of the faceplate has a plurality of spaced-apart cutting teeth, with an outward-facing hair guide groove formed between adjacent cutting teeth. An open groove is provided in the faceplate, penetrating the faceplate to allow hair to move along the length of the faceplate, and an inward-facing hair guide groove is provided in each cutting tooth, communicating with the open groove.

[0006] Optionally, a plurality of the cutting teeth arranged at intervals constitute a cutting tooth group, and the length of the open slot is equal to, greater than or less than the length of the cutting tooth group.

[0007] Optionally, the open slot is smaller than the length of the cutting tooth group, and the open slot is centrally located along the cutting tooth group or located at either end of the cutting tooth group.

[0008] Optionally, both sides of the panel are provided with cutting tooth groups, and the cutting teeth in the two cutting tooth groups are relatively staggered or symmetrically arranged.

[0009] Optionally, the open slot is provided with a partition block, which divides the open slot into two parts to form a first open slot and a second open slot.

[0010] Optionally, the open slot is provided with a plurality of connecting blocks perpendicular to the open slot, so that the open slot forms a plurality of relatively independent hair inlet areas.

[0011] Optionally, a side opening groove is provided on the side plate, and the side opening groove is connected to the outer guide groove.

[0012] Optionally, the side-opening slot includes a plurality of staggered first side-opening sub-slots and second side-opening sub-slots, wherein the first side-opening sub-slot and its connected external guide groove form a "U" shape, and the second side-opening sub-slot and its connected external guide groove form a "T" shape.

[0013] Optionally, the inner guide groove and the outer guide groove are staggered or on the same straight line.

[0014] Optionally, the panel is in an arc shape that curves upward or downward in the orthographic projection direction of the outer surface of the side panel; the panel is in an arc shape that curves upward or downward in the orthographic projection direction at either end of its two ends.

[0015] In the technical solution of this invention, the razor includes a blade body, which has a panel that contacts the skin and a side plate connected to the panel on at least one side of the panel. At least one edge of the panel has a plurality of spaced-apart cutting teeth, with an outward-facing hair-guiding groove formed between adjacent cutting teeth. An open groove is provided in the panel, penetrating the panel and allowing hair to move along the length of the panel. An inner hair-guiding groove, opening inward and communicating with the open groove, is provided in each cutting tooth. It can be understood that by providing an open groove in the panel and an inner hair-guiding groove in the cutting teeth, this invention enables hair to move not only along the length of the panel in the open groove but also along the width of the panel during shaving. This achieves hair guidance and capture in both the length and width directions of the panel, greatly improving the hair guidance and capture capabilities and effectively enhancing the shaving effect.

[0028] This invention proposes a razor, especially a hair razor, etc., which is not limited thereto.

[0029] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the razor includes a blade body, the blade body having a panel 10 that contacts the skin and a side plate 20 that is disposed on at least one side of the panel 10 and connected to the panel 10. A plurality of spaced cutting teeth 11 are provided at at least one edge of the two sides of the panel 10, and an outward-facing hair guide groove 101 is formed between two adjacent cutting teeth 11. An open groove 102 is provided in the panel 10, which penetrates the panel 10 and allows hair to move along the length direction of the panel 10, and an inner hair guide groove 103 with an inward-facing opening and communicating with the open groove 102 is provided in each cutting tooth 11.

[0030] In this embodiment, the open slot 102 can be a three-dimensional space extending along the length of the panel between the cutting teeth 11 arranged opposite to each other on both sides of the panel 10. This three-dimensional space can be a single structure or composed of multiple spaced sub-spaces, and is not limited here. By providing a three-dimensional open slot 102 on the panel 10, hair extending in different directions can be guided and captured by the open slot 102 of the panel 10.

[0031] The inner hair guide groove 103 can also be a three-dimensional space in two adjacent cutting teeth 11 along the length direction of the panel 10. This three-dimensional space is connected to the aforementioned open groove 102 three-dimensional space to jointly guide and capture hair, so that the hair entering can move along the length direction of the panel 10 and also along the width direction of the panel 10.

[0032] It is understood that by providing an open groove 102 in the panel 10 and an inner hair guide groove 103 in the cutting teeth 11, the present invention enables hair to move not only along the length direction of the panel 10 in the open groove 102, but also along the width direction of the panel 10 in the inner hair guide groove 103 during shaving. In other words, the shaver can guide and capture hair not only in the width direction of the panel 10, but also in the length direction of the panel 10, which greatly improves the ability to guide and capture hair and effectively improves the shaving effect.

[0033] Reference Figures 1 to 5 In some embodiments, a plurality of spaced cutting teeth 11 form a cutting tooth group along the length of the panel 10, and the length of the open slot 102 may be equal to, greater than or less than the length of the cutting tooth group.

[0034] In this embodiment, the several spaced cutting teeth 11 are regarded as a whole cutting tooth group. With the cutting tooth group as a reference, the length of the open groove 102 can be the same as the cutting tooth group, or it can be longer or shorter than the cutting tooth group.

[0035] Furthermore, when the open slot 102 is less than the length of the cutting tooth assembly, the open slot 102 can be centrally located along the cutting tooth assembly or located at either end of the cutting tooth assembly; there is no limitation on this.

[0036] In other words, any method that moves the introduced hair along the length of the panel 10 by providing an open slot 102 in the middle of the panel 10 is within the scope of this invention.

[0037] To further improve the shaving effect, in one embodiment, both sides of the panel 10 can be provided with a cutting tooth group, and the cutting teeth 11 in the two cutting tooth groups are relatively staggered or symmetrically arranged.

[0038] Main reference Figure 4 In one embodiment, a partition block 12 may be provided in the open slot 102, dividing the open slot 102 into two parts to form a first open slot 1021 and a second open slot 1022. Thus, by adding the partition block 12 to the panel 10, the movement space of hair along the width direction of the open slot 102 can be relatively restricted, accelerating the entry of hair into the inner guide slot 103, thereby improving shaving efficiency. Furthermore, providing the partition block 12 on the panel 10 can also improve the overall strength of the panel 10, thereby enhancing the deformation resistance of the razor's stationary blades.

[0039] To further enhance the effectiveness and efficiency of hair cutting, the main reference is... Figure 5 In one embodiment, a plurality of connecting blocks 13 perpendicular to the open slot 102 are provided in the middle of the open slot 102, so that the open slot 102 forms a plurality of relatively independent hair entry areas. In this way, the connecting blocks 13 divide the open slot 102 into multiple parts, making the open slot 102 a de facto hair cutting groove, blocking the lateral movement of hair and cooperating with the moving blade to cut the hair, so that the hair can be cut without entering the inner hair guide groove 103, and the connecting blocks 13 can also improve the working strength of the two cutting tooth groups.

[0040] In this embodiment, the connecting block 13 can prevent the hair from moving laterally and can work with the moving blade to cut the hair, thereby further improving the shaving efficiency.

[0041] In existing technologies, some razors have stationary blades located on the upper surface of the stationary blade, with hair being guided and captured from the upper surface. However, the left and right sides of the stationary blade do not have hair guiding and capturing functions, resulting in a relatively poor trimming effect and efficiency.

[0042] In this regard, the present invention has made the following improvements:

[0043] Reference Figures 1 to 5 In some embodiments, a side open groove 201 is provided on the side plate 20, and the side open groove 201 is connected to the outer guide groove 101 to form a three-dimensional spatial structure.

[0044] It is understood that during the hair cutting process, the hair can enter the razor from at least two directions, namely the open slot 102 on the panel 10 and the side open slot 201 on the side plate 20, for hair cutting. During the hair entry process, hair in any direction can be captured by the three-dimensional space formed by the open slot 102 and the inner hair guide slot 103 or the three-dimensional space formed by the side open slot 201 and the outer hair guide slot 101, thereby greatly improving the hair trimming effect and cutting efficiency.

[0045] To further improve hair import and capture effects, the main reference is... Figure 3 In one embodiment, the side open slot 201 includes a plurality of staggered first side open sub-slots 2011 and second side open sub-slots 2012. The first side open sub-slot 2011 and the external guide groove 101 connected to it form a "U" shape, and the second side open sub-slot 2012 and the external guide groove 101 connected to it form a "T" shape.

[0046] Furthermore, the inner hair guide groove 103 and the outer hair guide groove 101 can be staggered to make the most of the space in the panel 10 and make the size of the shaver more compact. Of course, if the panel 10 is large enough, the inner hair guide groove 103 and the outer hair guide groove 101 can be on the same straight line.

[0047] Additionally, refer to Figure 1 , Figures 3 to 5 In some embodiments, the panel 10 is in an arc shape that is curved upward or downward in the orthographic projection direction of the outer surface of the side panel 20, and the panel 10 is in an arc shape that is curved upward or downward in the orthographic projection direction of either end of its two ends.

[0048] The present invention uses a convex or concave static blade panel 10. Compared with the existing static blades with flat shaving surfaces, the static blade teeth of the present invention have a smaller contact area with the skin during the shaving process, which effectively improves the comfort of shaving.

[0049] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
