Abstract
Description
Technical Field
[0001] This application relates to the field of shaving, and more particularly to a shaving system. Background Technology
[0002] like Figure 1 As shown, in the existing shaver head, the front side of its head frame has a contact structure 210 that slides in contact with the elastic skin 300 during shaving. The contact structure 210 is located directly in front of the blade 221 of the shaver head blade 220. The contact structure 210 is also flush with the blade 221 of the shaver head blade 220 along the direction from front to back of the head frame (see the direction indicated by arrow B).
[0003] Therefore, during the shaving process of the existing razor head, the elastic skin 300 protrudes from top to bottom along the head frame (see the direction indicated by arrow C) between the contact structure 210 and the blade 221. The blade 221 presses against the protruding position 310 of the elastic skin 300, which causes the blade 221 to irritate or even scratch the elastic skin 300 during the shaving process 230, thus affecting the shaving comfort.
[0004] Therefore, there is an urgent need for a shaving system to overcome the above-mentioned defects.
[0005] Application content
[0006] The purpose of this application is to provide a shaving system that ensures the blades smoothly cut the hair on the skin to ensure a comfortable shaving experience.
[0007] To achieve the above objectives, the shaving system of this application includes a shaving head frame, a blade, a left retainer, and a right retainer. The shaving head frame has a receiving space, in which the blade is located and extends along the left-right direction of the shaving head frame. The left and right ends of the blade are supported by the shaving head frame, and the cutting edge of the blade faces the front of the shaving head frame. The left retainer extends horizontally across the left end of the blade from above and is fitted to the shaving head frame. The left retainer, together with the shaving head frame, clamps the left end of the blade. The right retainer extends horizontally across the right end of the blade from above and is fitted to the shaving head frame. The right retainer, together with the shaving head frame, clamps the right end of the blade. The front side of the shaving head frame has an inclined extension structure that extends downwards towards the cutting edge of the blade. The inclined extension structure is located between the left and right retainers along the left-right direction of the shaving head frame, and the highest point of the inclined extension structure is higher than the cutting edge of the blade adjacent to the inclined extension structure.
[0008] Preferably, the lowest point of the inclined extension structure is higher than the cutting edge of the blade adjacent to the inclined extension structure.
[0009] Preferably, the inclined extension structure extends rearward to a position protruding from the front side of the cutter head frame to enclose the wall of the receiving space; or, the inclined extension structure extends rearward to a position flush with the front side of the cutter head frame to enclose the receiving space; or, the inclined extension structure extends rearward to a position at a predetermined gap from the front side of the cutter head frame to enclose the receiving space.
[0010] Preferably, the inclined extension structure has a plurality of guide channels arranged at intervals along the left and right directions of the cutter head frame. The guide channels extend along the front and back directions of the cutter head frame and also penetrate the top, front and back of the inclined extension structure. The guide channels divide the inclined extension structure into a corresponding number of strip-shaped comb teeth.
[0011] Preferably, the front and / or rear ends of the strip-shaped comb teeth are each provided with a chamfer.
[0012] Preferably, the strip-shaped comb teeth and the guide channel extend in an arc shape, and the arc centers of the strip-shaped comb teeth and the guide channel coincide.
[0013] Preferably, all the guide channels are arranged at equal intervals.
[0014] Preferably, the inclined extension structure has chamfers at its front end and / or rear end.
[0015] Preferably, the projection of the top profile of the inclined extension structure onto the transverse plane is an arc, the extension of which extends from below the cutting edge adjacent to the inclined extension structure, and the cutting edge adjacent to the inclined extension structure is perpendicular to the transverse plane.
[0016] Preferably, a protective member is mounted on the front side of the cutter head frame in front of the inclined extension structure, and a lubricating strip is mounted on the rear side of the cutter head frame. The protective member and the lubricating strip extend along the left and right directions of the cutter head frame, and the protective member and the lubricating strip are located between the left fixing member and the right fixing member.
[0017] Compared to existing technologies, the shaving head frame has an inclined extension structure on its front side that extends downward toward the blade edge. This inclined extension structure is located between the left and right fixing members along the left-right direction of the shaving head frame, and its highest point is higher than the blade edge adjacent to it. Therefore, during shaving, the elastic skin between the highest point of the inclined extension structure and the blade edge gradually extends downward and backward along the inclined extension structure. In other words, the forward-high and backward-lower angle of the inclined extension structure provides space for the elastic skin to gradually extend downward and backward, and the elastic skin that extends downward and backward is guided toward the blade edge along the inclined extension structure. This allows the blade to smoothly cut the hair on the elastic skin, reducing irritation and even scratches, thus ensuring a comfortable shaving experience. Attached Figure Description

[0023] To illustrate the technical content and structural features of this application in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0024] Please see Figures 2 to 4 The shaving system 100 of this application includes a head frame 10, three blades 20, a left retainer 30, and a right retainer 40. The head frame 10 has a receiving space 11. Preferably, the head frame 10 is square, and correspondingly, the receiving space 11 is also square, so that the receiving space 11 can maximize the utilization of the size of the head frame 10. Of course, the head frame 10 and the receiving space 11 can also be other shapes, so it is not limited to these. Figure 2As shown in the diagram; the blade 20 is located in the receiving space 11 and extends along the left and right direction of the cutter head frame 10. The left and right ends of the blade 20 are supported by the cutter head frame 10 from below. The cutting edge 21 of the blade 20 faces the front of the cutter head frame 10. The left fixing member 30 crosses the left end of the blade 20 from above and is assembled to the cutter head frame 10. The left fixing member 30 and the cutter head frame 10 together clamp the left end of the blade 20. The right fixing member 40 crosses the right end of the blade 20 from above and is assembled to the cutter head frame 10. The right fixing member 40 and the cutter head frame 10 together clamp the left end of the blade 20. The frame 10 together clamps the right end of the blade 20, that is, the left end of the blade 20 is secured by the left fixing member 30 and the blade head frame 10, and the right end of the blade 20 is secured by the right fixing member 40 and the blade head frame 10; the front side 12 of the blade head frame 10 has an inclined extension structure 50 that extends downward toward the cutting edge 21 of the blade 21. The inclined extension structure 50 is located between the left fixing member 30 and the right fixing member 40 in the left-right direction of the blade head frame 10. The highest point 51 of the inclined extension structure 50 is higher than the cutting edge 21 of the blade 20 adjacent to the inclined extension structure 50, as shown in the figure. Figure 5 As shown in the enlarged image, during the shaving process, the inclined extension structure 50 pairs of elastic skin 300 (see...) Figure 5 The elastic skin 300 is pressed against the left and right fixing members 30 and 40 along the left and right directions of the shaving head frame 10, causing it to flow along the inclined extension structure 50 to the cutting edge 21 of the blade 20. This allows the cutting edge 21 of the blade 20 to smoothly cut the hair 230 on the elastic skin 300, reducing irritation and even scratches to the elastic skin 300, thus ensuring a comfortable shaving experience. It should be noted that... Figure 2 and Figure 3 In this configuration, the left end of the inclined extension structure 50 extends to a position adjacent to the left fixing member 30, and the right end of the inclined extension structure 50 extends to a position adjacent to the right fixing member 40, so that the dimension of the inclined extension structure 50 in the left-right direction of the cutter head frame 10 occupies as much space as possible between the left fixing member 30 and the right fixing member 40. Of course, depending on actual needs, the dimension of the inclined extension structure 50 in the left-right direction of the cutter head frame 10 can be 0.5 to 0.95 times the distance between the left fixing member 30 and the right fixing member 40; furthermore, although Figures 2 to 4 The number of blades shown is three, but of course, depending on the actual needs, one, two, or four can be selected. Therefore, it is not specified. Figures 2 to 4 The above is a limited description; furthermore, the cutting edge 21 can be considered a straight line structure. More specifically, as follows:
[0025] like Figures 2 to 4As shown, a protective member 60 is mounted on the front side 12 of the shaving head frame 10, located in front of the inclined extension structure 50. A lubricating strip 70 is mounted on the rear side 14 of the shaving head frame 10. The protective member 60 and the lubricating strip 70 extend along the left and right directions of the shaving head frame 10, respectively, and are located between the left fixing member 30 and the right fixing member 40. During shaving, the protective member 60 provides tension to the elastic skin 300 located in front of the inclined extension structure 50, and the lubricating strip 70 provides lubrication to the elastic skin 300 located behind the blade 20. For example, the protective member 60 is a rolling element, so that the protective member 60 contacts the elastic skin 300 in a rolling manner during shaving. Of course, depending on actual needs, the protective member 60 can also be made into a structure fixed to the front side 12 of the shaving head frame 10, so it is not necessary to use the protective member 60. Figures 2 to 4 The illustration is for illustrative purposes only. It is understood that, depending on actual needs, one or both of the protective component 60 and the lubricating strip 70 may be removed.
[0026] like Figure 4 As shown, the lowest point 52 of the inclined extension structure 50 is higher than the cutting edge 21 of the blade 20 adjacent to the inclined extension structure 20 (i.e., Figure 4 The leftmost blade 20's cutting edge 21 is designed to further prevent the elastic skin 300, which extends gradually downwards and backwards along the inclined extension structure 50 from front to back along the blade frame 10, from bulging downwards relative to the cutting edge 21 of the blade 20 adjacent to the inclined extension structure 20, thus further reducing the irritation or even scratching of the elastic skin 300 by the cutting edge 21. Specifically, in Figure 4 In the middle, the projection of the top profile of the inclined extension structure 50 onto the transverse plane P is an arc L1, and the extension line L2 of the arc L1 (see Figure 4 (As shown by the dashed line in the enlarged view) Extending from below the cutting edge 21 adjacent to the inclined extension structure 50, the cutting edge 21 adjacent to the inclined extension structure 50 is perpendicular to the transverse plane P. This design aims to minimize the downward bulge of the elastic skin 300, which gradually extends backward and downward along the inclined extension structure 50 in the direction from front to back along the blade frame 10, relative to the cutting edge 21 of the blade 20 adjacent to the inclined extension structure 20. More specifically, in Figure 4 In the middle, the inclined extension structure 50 has a chamfer 55 at its front end and / or rear end to ensure smooth contact between the inclined extension structure 50 and the elastic skin 300. Of course, the chamfer 55 can be deleted according to actual needs, so it is not required. Figure 4 The above is the limit.
[0027] like Figure 4As shown, the inclined extension structure 50 extends rearward to a position flush with the wall 13 of the front side 12 of the cutter head frame 10 used to enclose the receiving space 11, as shown in the figure. Figure 4 As shown in the enlarged view, this design aims to facilitate the molding of the blade frame 10 while ensuring that the inclined extension structure 50 gradually extends backward and downward relative to the elastic skin 300. Of course, depending on actual needs, the inclined extension structure 50 can also extend backward to a position protruding from the front side 12 of the blade frame 10 to enclose the wall 13 of the receiving space 11; or, the inclined extension structure 50 can extend backward to a position at a predetermined gap from the wall 13 of the front side 12 of the blade frame 10 used to enclose the receiving space 11. Therefore, it is not necessary to... Figure 4 The above is the limit.
[0028] like Figure 2 and Figure 3 As shown, the inclined extension structure 50 has multiple guide channels 53 spaced apart along the left and right directions of the blade frame 10. The guide channels 53 extend along the front and back directions of the blade frame 10 and also penetrate the top, front, and rear of the inclined extension structure 50. The guide channels 53 divide the inclined extension structure 50 into a corresponding number of strip-shaped comb teeth 54. This design ensures that the elastic skin 300 gradually stretches backward and downward along the inclined extension structure 50, while also facilitating the hair 230 on the elastic skin 300 to cross the inclined extension structure 50 along the guide channels 53. This is beneficial for the roots of the hair 230 to stand upright relative to the elastic skin 300, thus making it easier for the cutting edge 21 of the blade 20 adjacent to the inclined extension structure 50 to cut the hair 230. Specifically, in Figure 2 and Figure 3 In this configuration, all the guiding channels 53 are arranged at equal intervals to more effectively comb and guide the hair 230 of the elastic skin 300. Simultaneously, in... Figure 4 In this design, the strip-shaped comb teeth 54 and the guide channels 53 extend in an arc shape, with their arc centers coinciding to facilitate manufacturing and processing. It should be noted that, as described above, the inclined extension structure 50 has chamfers 55 at its front and / or rear ends. When the inclined extension structure 50 is divided into a corresponding number of strip-shaped comb teeth 54 by multiple guide channels 53, the front and / or rear ends of the strip-shaped comb teeth 54 will correspondingly have chamfers 55. Furthermore, when the inclined extension structure 50 does not require guide channels 53, the inclined extension structure 50 will not be divided into a corresponding number of strip-shaped comb teeth 54.
[0029] Compared with the prior art, the front side 12 of the shaving head frame 10 has an inclined extension structure 50 that extends downward toward the cutting edge 21 of the blade 20. The inclined extension structure 50 is located between the left fixing member 30 and the right fixing member 40 in the left-right direction of the shaving head frame 10. The highest point 51 of the inclined extension structure 50 is higher than the cutting edge 21 of the blade 20 adjacent to the inclined extension structure 50. Therefore, during shaving, the elastic skin 300 located between the highest point 51 of the inclined extension structure 50 and the cutting edge 21 of the blade 20 gradually stretches backward and downward along the inclined extension structure 50. That is to say, the front-high and rear-low of the inclined extension structure 50 provides space for the elastic skin 300 located between the inclined extension structure 50 and the cutting edge 21 of the blade 20 to gradually stretch backward and downward, and the elastic skin 300 stretching backward and downward is guided along the inclined extension structure 50 toward the cutting edge 21 of the blade 20. See the state. Figure 5 As shown, this allows the blade 21 to smoothly cut the hair 230 on the elastic skin 300, reducing irritation or even scratches to the elastic skin 300, thus ensuring a comfortable shaving experience.
[0030] It should be noted that arrow A in the attached diagram points from left to right on the cutter head frame 10, arrow B points from front to back on the cutter head frame 10, and arrow C points from top to bottom on the cutter head frame 10; furthermore, although Figure 2 and Figure 3 The left fixing member 30 and the right fixing member 40 shown are two independent and separate plate-shaped components. Of course, depending on actual needs, the left fixing member 30 and the right fixing member 40 can be connected into a single component. Therefore, they are not considered as separate components. Figure 2 and Figure 3 The above is the limit.
[0031] The above-disclosed examples are merely preferred embodiments of this application and should not be construed as limiting the scope of this application. Therefore, any equivalent variations made in accordance with the claims of this application shall still fall within the scope of this application.
