Referring to fig. 4 to 6, a razor head with non-cutting members according to a second embodiment of the present invention is shown, the razor head 100' of this embodiment has substantially the same structure as the razor head 100 of the first embodiment, and the differences between the two embodiments are the non-cutting members, and the differences are as follows:

(1) in the present embodiment, there are two non-cutting members 30 ', and correspondingly, the two non-cutting members 30' divide the assembly accommodating chamber 15 into three assembly accommodating chamber units 151, so the number of the blades 20 is three. In the first embodiment, the number of the blades 20 is two because the non-cutting member 30 is one and divides the fitting accommodation chamber 15 into two fitting accommodation chamber units 151.

(2) In the present embodiment, the top surface 31 of the non-cutting member 30' is a plane, preferably, the front and rear corners of the top surface 31 are circular arc transitions; in the first embodiment, the top surface 31 of the non-cutting member 30 is an arc curved surface which is arched along the front-to-rear direction of the tool bit frame 10, the top surface 31 of the non-cutting member 30 has a plurality of comb teeth protruding strips 32 which are arranged at intervals along the left-right direction of the tool bit frame 10 and extend along the front-to-rear direction of the tool bit frame 10, the comb teeth protruding strips 32 are arched along the front-to-rear direction of the tool bit frame 10, the non-cutting member 30 is provided with hollow cavities 33 which penetrate through the tool bit frame 10 in the up-and-down direction, and a hollow cavity 33 is formed between two adjacent comb teeth protruding strips 32.

Except for the differences (1) and (2), they are the same as those of the first embodiment, and thus are not described herein again.

Referring to fig. 7, a third embodiment of the razor head with non-cutting members of the present invention is shown, and the razor head with non-cutting members 100 ″ of this embodiment has substantially the same structure as the razor head with non-cutting members 100 of the first embodiment, with the following differences:

(a) in the third embodiment, the cutter head frame 10 is divided into an upper cover 10a and a lower frame 10b which are coupled to each other in a covering manner in the up-down direction of the cutter head frame 10, the upper cover 10a and the lower frame 10b clamp the cutter blade 20 together, and the non-cutting member 30 and the upper cover 10a constitute an integrated structure together, so that the cutter blade 20 can be assembled and fixed quickly by the covering coupling of the upper cover 10a and the lower frame 10 b. In the first embodiment, the blades 20 are pressed by the clips 40 mounted on the bit frame 10. It should be noted that, because the upper cover 10a and the lower frame 10b are covered and connected together, before the covering and connecting, the upper cover 10a and the lower frame 10b are two independent parts, that is, they are manufactured separately, and at the same time, the upper cover 10a and the lower frame 10b can be covered and connected together through the inserting and connecting fit between the inserting column and the inserting slot hole, so that the upper cover 10a and the lower frame 10b have the disassembling function, of course, the upper cover 10a and the lower frame 10b can be covered and connected together through the glue connection, the ultrasonic welding, and the like, so that the upper cover 10a and the lower frame 10b do not have the disassembling function; in addition, since the head frame 10 is divided into the upper cover 10a and the lower frame 10b which are coupled to each other in a covering manner, and the head frame 10 includes the front wall 11, the rear wall 12, the left wall 13, and the right wall 14, some or all of the front wall 11, the rear wall 12, the left wall 13, and the right wall 14 may be divided into upper and lower portions.

(b) In the third embodiment, the guard member 50 and the lubricating strip 60 may not be provided.

Except for the above differences, the other embodiments are the same as the first embodiment, and therefore, the description thereof is omitted.

Compared with the prior art, since the non-cutting member 30(30 ') is located in the assembly accommodating cavity 15 and extends in the left-right direction of the bit frame 10, the non-cutting member 30(30 ') is further spaced apart from the blade 20 in the front-rear direction of the bit frame 10, and the left end of the non-cutting member 30(30 ') and the left side wall 13 and/or the right end of the non-cutting member 30(30 ') and the right side wall 14 together form an integral structure, the non-cutting member 30(30 ') and the bit frame 10 are formed by integral forming (such as, but not limited to, injection molding), the assembly step between the existing non-cutting member and the bit frame and a separate mold opening are omitted, so that the manufacturing process is simplified and the cost is reduced.

It should be noted that the direction indicated by the arrow a in the drawing is a direction from left to right of the cutter head frame 10, the direction indicated by the arrow B in the drawing is a direction from front to back of the cutter head frame 10, and the direction indicated by the arrow C in the drawing is a direction from top to bottom of the cutter head frame 10, so that the left and right directions of the cutter head frame 10 are the direction indicated by the arrow a and the opposite direction, the front and back directions of the cutter head frame 10 are the direction indicated by the arrow B and the opposite direction, and the up and down directions of the cutter head frame 10 are the direction indicated by the arrow C and the opposite direction. Further, the non-cutting member 30 (30') referred to herein means a member having no shaving function or cutting function, and functions to divide the set receiving chamber 15 into a corresponding number of set receiving chamber units 151 to establish a preferable exposure position of the blade 20 with the front and rear side walls 11 and 12 of the head frame 10, respectively.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be limited thereto, since the equivalent changes and modifications of the present invention are intended to fall within the scope of the present invention.
