[0019] Figure 2 is Figure 1 the three-dimensional exploded structural schematic diagram of the cutting type cutter head shown.

[0020] Figure 3 is along Figure 1 the planar structural schematic diagram projected in the direction indicated by the arrow C in Detailed Description of the Embodiments

[0021] In order to elaborate in detail the technical content and structural features of the present invention, the following further description is made in conjunction with the embodiments and with reference to the drawings.

[0022] Please refer to Figures 1 to 3 , the cutting type cutter head 100 of the present invention includes a cutter head frame 10, a blade 20 and a clip 30. The cutter head frame 10 is provided with an assembly accommodation cavity 111 for assembling and accommodating the blade 20. Preferably, the assembly accommodation cavity 111 is located in the middle of the cutter head frame 10 and is designed as a square cavity, so that the length direction of the assembly accommodation cavity 111 is arranged along the left-right direction of the cutter head frame 10, and the width direction of the assembly accommodation cavity 111 is arranged along the front-back direction of the cutter head frame 10, thereby improving the utilization rate of the cutter head frame 10; of course, according to actual needs, the assembly accommodation cavity 111 can also be designed into other shapes, so it is not limited thereto; the blade 20 is located in the assembly accommodation cavity 111, the cutting edge 21 of the blade 20 faces the front of the cutter head frame 10, the left end of the blade 20 is embedded in the left side 11 of the cutter head frame 10, the right end of the blade 20 is embedded in the right side 12 of the cutter head frame 10, and the cutter head frame 10 supports the blade 20; the clips 30 are respectively assembled on the left and right sides 11(12) of the cutter head frame 10 and press the left and right ends of the blade 20 to prevent the blade 20 from running out of the cutter head frame 10 during shaving. Preferably, in Figures 1 to 3Among them, the clip 30 located on the left side 11 of the cutter head frame 10 and the clip 30 located on the right side 12 of the cutter head frame 10 are independent of each other and not connected to each other. Of course, according to actual needs, they can be integrated into one body. Specifically, an intermediate connecting bar is provided between them, so it is not limited to the drawings; on the front side 13 of the cutter head frame 10, there are seventeen comb-shaped ridges 40 arranged at intervals in the left-right direction of the cutter head frame 10 and extending forward along the cutter head frame 10. The comb-shaped ridges 40 are located in front of the cutting edge 21 of the blade 20, and the comb-shaped ridges 40 are also inclined relative to the plane P1 perpendicular to the cutting edge 21 of the blade 20. The state is shown in Figure 3 as shown. Specifically, in Figures 1 to 3 Among them, the comb-shaped ridges 40 are symmetric about the left and right to ensure that the shape of the diversion channel 40a surrounded by two adjacent comb-shaped ridges 40 for guiding hair during shaving is regularly arranged, improving the reliability of hair diversion. It can be understood that according to actual needs, the number of the comb-shaped ridges 40 can also be two, three, four, five or six, etc., which is determined by the left-right size of the blade frame 10, so it is not limited to the drawings. More specifically, as follows:

[0023] As Figure 3 shown, the inclination angle α of the left-right symmetry plane P2 of the comb-shaped ridge 40 relative to the plane P1 perpendicular to the cutting edge 21 of the blade 20 is greater than 0 and less than 90 degrees; specifically, the inclination angle α of the left-right symmetry plane P2 of the comb-shaped ridge 40 relative to the plane P1 perpendicular to the cutting edge 21 of the blade 20 is greater than 0 and less than or equal to 10 degrees, such as 1 degree, 2 degrees, 3 degrees, 4 degrees, 5 degrees, 6 degrees, 7 degrees, 8 degrees, 9 degrees or 10 degrees. Such a design enables the hair to flow to the cutting edge 21 of the blade 20 at the most suitable inclination angle during shaving, effectively avoiding the serious defect that the cutting type razor head 100 of the present invention moves back and forth in its left-right direction when the hair flows to the cutting edge 21 of the blade 20 at a large inclination angle. More specifically, in Figure 3 Among them, the projection of the comb-shaped ridge 40 in the up-down direction of the cutter head frame 10 is a straight strip for the convenience of manufacturing the comb-shaped ridge 40. Of course, in other embodiments, the projection of the comb-shaped ridge 40 in the up-down direction of the cutter head frame 10 is a curved strip, such as the curved strip is an "S" strip, so it is not limited to the drawings.

[0024] As Figures 1 to 3 shown, the cutting type razor head 100 of the present invention further includes a protective member 50 installed on the front side 13 of the cutter head frame 10. The comb-shaped ridges 40 are simultaneously formed on the protective member 50 and the front side 13 of the cutter head frame 10 so that the distance between the comb-shaped ridges 40 and the cutting edge 21 of the blade 20 is smaller; of course, according to actual needs, the comb-shaped ridges 40 can be formed only on the protective member 50, so it is not limited to the drawings. Specifically, in Figures 1 to 3In the embodiment, the comb teeth ridge 40 includes a first portion 41 formed on the protective member 50 and a second portion 42 formed on the front side 13 of the cutter head frame 10, and the first portion 41 and the second portion 42 extend in abutment with each other. Figure 1 In the embodiment, the rear end of the first part 41 extends an embedding structure 411 embedded in the second part 42, and the second part 42 is provided with an embedding space 421 for the embedding structure 411 to be embedded. The embedding structure 411 of the first part 41 is higher than the second part 42. This design makes it possible for the skin to not contact the second part 42 when sliding along the first part 41 to the second part 42 during shaving, and needs to continue to slide over the embedding structure 41 before being supported by the second part 42, thereby reducing the amount of skin sinking in the space between the blade 21 of the blade 20 and the embedding structure 41, thereby improving the hair cutting effect of the blade 20 and avoiding damage to the skin. More specifically, in Figures 1 to 3 In the embodiment, the first part 41 includes a front extension 41a and a lower extension 41b bent downward from the end of the front extension 41a. The size of the front extension 41a along the left and right direction of the cutter head frame 10 is arranged to be large in the middle and small at the front and rear ends. The intersection of the lower extension 41b and the front extension 41a is an arc transition 41c. This design makes the guide channel 40a surrounded by two adjacent comb tooth ridges 40 large at the front and rear ends and small in the middle, so as to facilitate the operation of capturing hair in the front and releasing hair in the back. For example, the first part 41 is a flexible material, such as but not limited to silicone material; the second part 42 is a hard material, such as but not limited to plastic, so that the second part 42 is molded together during the injection molding process of the cutter head frame 10. This design can improve shaving comfort.

[0025] In order to improve the shaving comfort, a lubricating strip 50 is installed on the rear side 14 of the cutter head frame 10. Of course, the lubricating strip 50 can be deleted according to actual needs, so it is not limited to this. Figures 1 to 3 In the embodiment, all the comb teeth protrusions 40 are aligned with each other and arranged in a row along the right-hand direction of the cutter head frame 10. Preferably, all the comb teeth protrusions 40 are arranged in a row at equal intervals, but not limited thereto.

[0026] Compared with the prior art, since there are a plurality of comb teeth ridges 40 spaced apart in the left-right direction of the cutter head frame 10 and extending forward along the cutter head frame 10 on the front side 13 of the cutter head frame 10, the comb teeth ridges 40 are located in front of the cutting edge 21 of the blade 20, and the comb teeth ridges 40 are also inclined relative to the plane P1 perpendicular to the cutting edge 21 of the blade 20; therefore, during shaving, the hairs collected and diverted by the comb teeth ridges 40 flow to the cutting edge 21 of the blade 20 in a direction inclined relative to the cutting edge 21 of the blade 20. Thus, while the cutting edge 21 of the blade 20 performs a pulling cut action on the hairs, there is also a cutting action, realizing the cutting action of the cutting edge 21 of the blade 20 on the hairs and reducing the force received by each hair when being cut, so that while improving the shaving effect, the skin pulling pain can be reduced and the shaving comfort can be improved.

[0027] It should be noted that the direction indicated by the arrow A in the drawings is the left-to-right direction of the cutter head frame 10, the direction indicated by the arrow B in the drawings is the front-to-back direction of the cutter head frame 10, and the direction indicated by the arrow C in the drawings is the up-to-down direction of the cutter head frame 10. Therefore, the left-right direction of the cutter head frame 10 is the direction indicated by the arrow A and the opposite direction, the front-back direction of the cutter head frame 10 is the direction indicated by the arrow B and the opposite direction, and the up-down direction of the cutter head frame 10 is the direction indicated by the arrow C and the opposite direction. In addition, although the drawings show that the number of blades 20 is only three, it can be one, two, four or five according to actual needs, but not limited thereto.

[0028] The above-disclosed are only the preferred examples of the present invention, and of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
