AI Technical Summary
The existing shaver head cannot effectively hold the hair during shaving, resulting in the hair roots being unable to extend outward and the shaving is not clean.
A cutting head frame is designed to include a structure with flexible and elastic flexible comb teeth on the front side wall. These flexible comb teeth are arranged in a longitudinal direction of the blade head frame and extend in a height direction to form free parts. During the shaving process, they are bent and deformed by the skin pushing and holding the hair together with the front side wall.
Through the bending deformation of the soft-elastic comb teeth and the cooperation of the front side wall, we can effectively hold the hair, so that the root of the hair is pulled outward during the movement of the blade head frame, achieving a cleaner shaving effect.

[0002] As everyone knows, in existing shavers, it can be divided into these two major categories of manual shavers and electric shavers. Wherein, for manual shavers, because it has the advantages of shaving more thoroughly and not needing power supply, so, it occupies the overwhelming majority of the share in the market.
[0003] Currently, in Figure 1 The existing razor head 100' shown comprises a razor head frame 10', a blade and a protective member 20'. The razor head frame 10' is composed of a front side wall 11', a rear side wall 12', a left side wall 13' and a right side wall 14'. The left end of the blade is mounted on the left side wall 13', and the right end of the blade is mounted on the right side wall 14'. The protective member 20' is mounted on the front side wall 11' and protrudes from the front side wall 11'. Therefore, during the shaving process of the existing razor head 100', the protective member 20' presses the hair 500 on the skin 400, so that the hair 500 contacts the skin 400; this causes the roots of the hair 500 to be unable to extend outward during the shaving process, thereby resulting in the defect of an unclean shave.
[0004] Therefore, there is an urgent need for a cutter head frame, a razor head and a razor to overcome one or more of the above-mentioned defects.

[0029] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.
[0030] See also Figure 2 , Figure 3 , Figure 5 and Figure 7 The razor 1000 of the present invention comprises a razor head 100 and a handle 200. The handle 200 is rotatably assembled with the razor head frame 10 in the razor head 100, so that the razor head 100 can rotate relative to the handle 200 during shaving to better fit the skin 400. Figure 2 , Figure 3 , Figure 5 and Figure 7 Although the handle 200 is shown to be directly assembled and connected to the cutter head frame 10 of the razor head 100, of course, in other embodiments, the handle 200 can also be indirectly assembled and connected to the cutter head frame 10 through an interconnecting member; when the interconnecting member is introduced, the handle 200 is slightly structurally adjusted due to the cooperation with the interconnecting member, but these are well known in the art; in addition, the present application does not involve any improvement on them, so they will not be described here.
[0031] Meanwhile, the razor head 100 comprises the aforementioned razor head frame 10 and a blade not shown in the figure. The blade extends along the longitudinal direction of the razor head frame 10 (i.e., the left and right direction of the razor head frame 10), and the blade is also assembled and connected with the left side wall 13 and the right side wall 14 described below, respectively, and the left and right side walls 14 provide support for the blade. Since the structure of the blade and the assembly method of the blade with the left side wall 13 and the right side wall 14 are well known in the art, they will not be described here.
[0032] Furthermore, the cutter head frame 10 includes a front side wall 11, a rear side wall 12, a left side wall 13, a right side wall 14, and seventeen flexible comb teeth 15 provided on the front side wall 11. The front side wall 11 extends along the longitudinal direction of the cutter head frame 10, and the rear side wall 12 extends along the longitudinal direction of the cutter head frame 10. The rear side wall 12 is also separated from the front side wall 11 along the transverse width direction of the cutter head frame 10 (i.e., the front-to-back direction of the cutter head frame 10). The left side wall 13 extends along the transverse width direction of the cutter head frame 10, and the left side wall 13 is also connected to the left ends of the front side wall 11 and the rear side wall 12 respectively. The right side wall 14 extends along the transverse width direction of the cutter head frame 10, and the right side wall 14 is also connected to the right ends of the front side wall 11 and the rear side wall 12 respectively, so as to meet the need that the front side wall 11, the rear side wall 12, the left side wall 13 and the right side wall 14 after being connected together form a substantially square frame. All the flexible comb teeth 15 are arranged in a spaced relationship along the longitudinal direction of the cutter head frame 10. The flexible comb teeth 15 are flexible and elastic, and the flexible comb teeth 15 also extend along the height direction of the cutter head frame 10 to form a free portion 15a. The free portion 15a is configured to be pushed by the skin 400 during the shaving process and bend and deform close to the front side wall 11, so that the front side wall 11 and the bent and deformed free portion 15a jointly hold the hair 500. Figure 6 and Figure 7 More specifically, as follows:
[0033] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, the front side wall 11 is provided with a groove 113 which passes through the front side surface 111 and the top surface 112 of the front side wall 11, and the groove 113 extends along the longitudinal direction of the cutter head frame 10 to a position adjacent to the left side wall 13 and the right side wall 14, that is, the groove 113 extends along the longitudinal direction of the cutter head frame 10 to a position adjacent to the left side wall 13, and the groove 113 also extends along the longitudinal direction of the cutter head frame 10 to a position adjacent to the right side wall 14, so as to control the groove 113 to be located between the left side wall 13 and the right side wall 14 along the longitudinal direction of the cutter head frame 10. The flexible comb teeth 15 are located in the grooves 113, and the free portions 15a also partially extend out of the grooves 113. This design allows the flexible comb teeth 15 to mainly occupy the inner position of the front side wall 11, thereby preventing the flexible comb teeth 15 from being placed outside the front side wall 11 and causing the size of the cutter head frame 10 to increase in the height direction due to being placed outside the front side wall 11. More importantly, by positioning the flexible comb teeth 15 in the grooves 113, the bent and deformed free portions 15a and the front side wall 11 (specifically, the top surface 112 of the front side wall 11) can more reliably hold the hair 500 together, and more effectively pull the roots of the hair 500 held in the gap 16 outward during the movement of the razor head 100, thereby further improving the cleanliness of the blade's shaving of the roots of the protruding hair 500.
[0034] like Figures 2 to 4 As shown, the free portion 15a is a cone-shaped structure, and the cone top 151 of the cone-shaped structure is far away from the front side wall 11. This design makes the size of the gap 16 increase along the height direction of the cutter head frame 10, so that the hair 500 can enter the gap 16 before the skin 40 pushes the free portion 15a to bend and deform. Figure 4 As an example, the two side surfaces 152 of the cone-shaped structure separated in the longitudinal direction of the cutter head frame 10 are symmetrically arranged to ensure that the size of the gap 16 is gradually increased along the height direction of the cutter head frame 10; of course, in other embodiments, the two side surfaces 152 of the cone-shaped structure opposite to each other in the longitudinal direction of the cutter head frame 10 may be asymmetrically arranged. Figure 4 Limits shown.
[0035] like Figures 5 to 7 As shown in FIG. 1 , in two adjacent flexible comb teeth 15, the end of the right free portion 15a is bent and deformed toward the left free portion 15a. Of course, in other embodiments, it can also be designed that in two adjacent flexible comb teeth 15, the ends of the free portions 15a of both are bent and deformed toward each other, so as to achieve the purpose of holding the hair 500 by the bent and deformed free portions 15a and the front side wall 11. Therefore, it is not necessary to Figures 5 to 7 Limits shown.
[0036] like Figures 2 to 3 As shown, all the flexible comb teeth 15 are arranged in a row at equal intervals on the front side wall 11 to ensure the uniformity of the arrangement of the flexible comb teeth 15 on the front side wall 11, thereby ensuring the consistency of the size of the gap 16 between any two adjacent flexible comb teeth 15; of course, in other embodiments, all the flexible comb teeth 15 can be arranged at equal intervals on the front side wall 11 and not in a row, so it is not necessary to Figures 2 to 3 In other embodiments, the number of the flexible comb teeth 15 can be other, which is flexibly selected by those skilled in the art according to the length of the front side wall 11 and the size of the flexible comb teeth 15. Figures 2 to 3 Limits shown.
[0037] Compared with the prior art, with the aid of a plurality of flexible and elastic comb teeth 15 which are arranged on the front side wall 11 and spaced apart along the longitudinal direction of the cutter head frame 10, and the flexible comb teeth 15 also extend along the height direction of the cutter head frame 10 to form a free portion 15a, the free portion 15a is configured to be pushed by the skin 400 (i.e., pushed by the skin 400) during shaving and bend and deform close to the front side wall 11, so that the front side wall 11 and the bent and deformed free portion 15a jointly hold the hair 500, so that the roots of the hair 500 are pulled outward during the movement of the razor head 100 on the skin 400, and the roots of the protruding hair 500 are shaved by the blade, so that the shaving is cleaner.
[0038] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
