Abstract
Description
Technical field
[0001] The utility model relates to a rotary shaver blade net capable of shaving long and short hairs, and also relates to a cutting assembly. [Background Technology]
[0002] The blade mesh of existing rotary shavers is usually stamped out of metal sheets, and the hair feed structure thereon is usually punched out or cut out by a grinding wheel. Since long hair is generally difficult to enter through the hair feed groove or hair feed hole, the existing blade mesh is generally used to shave short beards. The long hair here generally refers to beards or other hair that are longer than short beards. In order to shave long hair, some blade meshes will punch out serrations with one end suspended in the shaving ring corresponding to the outer shaving track, such as the Chinese patent No. CN111673801A, entitled "An Electric Shaver Net Cover". The serrations serve as fixed cutting teeth that cooperate with the movable cutting teeth of the movable knife to cut hair, thereby facilitating the entry and cutting of long hair. Since the serrations are a structure with one end suspended in the air, in order to ensure the structural strength of the serrations, the serrations usually have a relatively thick material thickness, or have a large width and a short length. However, if the saw teeth are wider, their number will be smaller, resulting in lower cutting efficiency. Since the movable cutting teeth of the movable blade need to be located on the inner side of the saw teeth to ensure safety, if the saw teeth are short, the effective cutting length of the saw teeth and the movable cutting teeth will be very small, resulting in lower cutting efficiency. Since the thickness of the same shaving ring is basically the same, a thicker material will make it difficult for the shaving ring where the saw teeth are located to shave hair cleanly, and can only shave long hairs short. Although a shaving ring with a conventional hair feed groove or hair feed hole structure is provided on the inner side of the outer shaving ring, and this shaving ring can be made very thin to shave hair cleanly, the shaving ring on the outer side generally has the greatest effect when shaving with a blade mesh. The shaving ring on the inner side occupies a smaller effective shaving area and has a relatively lower shaving efficiency, which significantly reduces shaving efficiency.
[0003] The present invention is made based on this situation. [Utility Model Content]
[0004] The technical problem to be solved by the utility model is to provide a rotary shaver blade net which can shave long and short hairs, has the characteristics of simple structure, and is convenient for shaving long hairs and cleanly shaving short hairs.
[0005] The utility model is realized through the following technical solutions:
[0006] A rotary shaver blade net capable of shaving long and short hairs comprises a blade net body, the blade net body being provided with a plurality of annular shaving tracks for rotating the movable cutting teeth of the movable blade, the top of the blade net body being provided with a shaving ring corresponding to each shaving track, the top of the shaving ring being upwardly raised in a plurality of areas and the thickness of the shaving ring being increased in the raised areas, thereby making the shaving ring have a thin area with a thin material thickness and a thick area with a thick material thickness, the thick area being provided with a tooth-shaped fixed cutting tooth with one end suspended, and the thin area being provided with a hair feeding hole and / or a hair feeding groove.
[0007] As described above, the rotary shaver blade net capable of shaving long and short hairs has the heads of the fixed cutting teeth provided with thickened heads.
[0008] As described above, in the rotary shaver foil capable of shaving long and short hairs, the material thickness T1 of the thick region is greater than the material thickness T2 of the thin region by more than 0.1 mm.
[0009] As described above, in the rotary shaver foil capable of shaving long and short hairs, the thick area is a fan-shaped area distributed on the shaving ring.
[0010] As described above, the rotary shaver blade net capable of shaving long and short hairs has two or more thick areas and two or more thin areas on the same shaving ring, and the thick areas and the thin areas are alternately arranged in the circumferential direction.
[0011] As described above, the rotary shaver blade foil capable of shaving long and short hairs has a smooth transition between the thick area and the thin area.
[0012] As described above, the rotary shaver blade net capable of shaving long and short hairs has two or more shaving rings provided inside and outside the shaving track, and the shaving rings corresponding to two adjacent shaving tracks are spaced apart or connected together.
[0013] As described above, the rotary shaver blade foil capable of shaving long and short hairs has a thin area and a thick area on the outermost shaving ring.
[0014] As described above, the blade net of the rotary shaver capable of shaving long and short hairs, the blade net body and the net top are formed by powder metallurgy, and the thin area, thick area and fixed cutting teeth are formed by powder metallurgy.
[0015] As described above, the rotary shaver blade for shaving long and short hairs has a cutting edge with an acute angle on one side or both sides of the fixed cutting teeth.
[0016] Another technical problem to be solved by the present invention is to provide a cutting assembly which has the characteristics of simple structure, good safety, and is convenient for shaving long hair and cleanly shaving short hair.
[0017] The utility model is realized through the following technical solutions:
[0018] The cutting assembly of the rotary shaver blade net capable of shaving long and short hairs comprises a blade net and a movable blade, wherein the movable blade is provided with movable cutting teeth located in the shaving track and inside the head of the fixed cutting teeth.
[0019] As described above in the cutting assembly, the head of the fixed cutting tooth is provided with a thickened head, and the movable cutting tooth is located inside the thickened head.
[0020] Compared with the prior art, the utility model has the following advantages:
[0021] 1. The rotary shaver blade of this utility model has a thin area and a thick area within the same shaving ring. The thick area is thicker and has fixed cutting teeth thereon, which provide better structural strength. The fixed cutting teeth facilitate the entry and cutting of long hairs, while the thin area is thinner, allowing for a clean shave without leaving any hair roots too long. Therefore, within the same shaving ring, the fixed cutting teeth in the thick area facilitate shaving long hairs shorter, while the thin area facilitates a clean shave of short hairs.
[0022] 2. The rotary shaver blade of the present invention is in the same shaving ring. Since it can shave the thin area cleanly, it can avoid making the fixed cutting teeth thereon thin. The material thickness of the fixed cutting teeth is thick and has good structural strength, which is conducive to making the width of the fixed cutting teeth smaller so that more fixed cutting teeth can be provided within the same area. It is also conducive to making the length of the fixed cutting teeth longer, thereby increasing the effective cutting length of the fixed cutting teeth and the dynamic cutting teeth, and improving the cutting efficiency.
[0023] 3. The head of the fixed cutting tooth of the present invention is provided with a thickened thickening head, and the outward surface of the thickening head is smooth. The thickening head can avoid irritation to the skin when the head of the fixed cutting tooth is relatively small, so that the width of the fixed cutting tooth can be made smaller. Moreover, the thickening head reduces the width of the tooth groove entrance in the tooth groove formed between two adjacent fixed cutting teeth, which can better prevent the skin from squeezing in from the tooth groove entrance, thereby improving safety. On the basis that the dynamic cutting tooth is located on the inner side of the thickening head, the dynamic cutting tooth can be better leaned to the outside, thereby increasing the effective cutting length of the dynamic cutting tooth.
[0024] 4. The blade mesh body of the present invention is formed by powder metallurgy, which is conducive to forming thin areas, thick areas, fixed cutting teeth and thickened heads through powder metallurgy. It has a simple structure and a simple manufacturing process.

[0037] The present invention will be further described below with reference to the accompanying drawings:
[0038] like Figures 1 to 10 The rotary shaver blade net 100 shown in the figure, which can shave long and short hair, includes a blade net body 1, on which are provided a plurality of annular shaving tracks 2 for rotating the movable cutting teeth of the movable blade. The top 10 of the blade net body 1 is provided with a shaving ring 3 corresponding to each shaving track 2. The top of the shaving ring 3 protrudes upward in several areas, and the thickness of the shaving ring 3 in the protruding areas is increased, so that the shaving ring 3 has a thin area 31 with thin material thickness and a thick area 32 with thick material thickness. The thick area 32 is provided with a tooth-shaped fixed cutting tooth 4 with one end suspended in the air, and the thin area 31 is provided with a hair feeding hole 5 and / or a hair feeding groove 6.
[0039] During operation, the movable cutting teeth of the movable cutter rotate within the shaving track 2, along the top surface of the shaving track 2. During this rotation, the top surface of the shaving track 2 corresponding to the movable cutting teeth is circumferentially aligned or substantially aligned. The top surface of the shaving track 2 is also the bottom surface of the shaving ring 3. Several regions of the shaving ring 3 protrude upward from the top, forming thick regions 32. This results in a thin region 31 and a thick region 32 within the same shaving ring 3. The thick region 32 is thicker, and the fixed cutting teeth 4 disposed thereon provide greater structural strength. The fixed cutting teeth 4 facilitate entry and cutting of long hairs, while the thin region 31 is thinner, allowing for clean shaving and preventing hair roots from remaining excessively long. Therefore, within the same shaving ring 3, the fixed cutting teeth 4 in the thick region 32 facilitate shaving of long hairs, while the thin region 31 facilitates clean shaving of short hairs.
[0040] In the same shaving ring 3, since the thin area 31 is provided for shaving, the fixed cutting teeth 4 thereon can be prevented from being made thin. The material thickness of the fixed cutting teeth 4 is thick and has good structural strength, which is conducive to making the width of the fixed cutting teeth 4 smaller so that more fixed cutting teeth 4 can be provided within the same area. It is also conducive to making the length of the fixed cutting teeth 4 longer, thereby increasing the effective cutting length of the fixed cutting teeth 4 in cooperation with the dynamic cutting teeth and improving the cutting efficiency.
[0041] The outermost shaving ring 3 has a thin area 31 and a thick area 32, which is beneficial for shaving long hairs shorter and cleanly, thereby improving shaving efficiency.
[0042] like Figure 9 and Figure 10 The cutting assembly shown includes the blade net 100 and the movable blade 200. The movable blade 200 is provided with movable cutting teeth 201. The movable cutting teeth 201 are located in the shaving track 2 and the movable cutting teeth 201 are located on the inner side of the head of the fixed cutting teeth 4 to prevent the fixed cutting teeth 4 from cutting the skin.
[0043] like Figure 11 The shaving head shown has a plurality of cutting components including the blade net 100 arranged around the circumference of the shaving head frame 300, which can be used on a bald head machine. When used for shaving the head, the shaving head moves continuously against the scalp to better shave the hair.
[0044] Furthermore, if Figure 1-9As shown, the head of the fixed cutting tooth 4 is provided with a thickened thickening head 41, and the outward surface of the thickening head 41 is smooth. The thickening head 41 can avoid the head of the fixed cutting tooth 4 from irritating the skin when it is relatively small, so that the width of the fixed cutting tooth 4 can be made smaller, and the tooth groove formed between two adjacent fixed cutting teeth 4, the thickening head 41 reduces the width of the tooth groove entrance, which can better prevent the skin from squeezing in from the tooth groove entrance, thereby improving safety. On the basis that the dynamic cutting tooth 201 is located on the inner side of the thickening head 41, the dynamic cutting tooth 201 can be better leaned to the outside, thereby increasing the effective cutting length of the dynamic cutting tooth.
[0045] Preferably, the material thickness T1 of the thick area 32 is greater than the material thickness T2 of the thin area 31 by more than 0.1 mm. Preferably, the material thickness T2 of the thin area 31 can refer to the thickness of the knife net in the cutting area in the prior art, and T2 is between 0.08 mm and 0.15 mm.
[0046] The thick area 32 is a fan-shaped area distributed on the shaving ring 3, such as Figure 7 and Figure 8 In the embodiment shown, there may be more than two thick areas 32 and thin areas 31 on the same shaving ring 3, and the thick areas 32 and thin areas 31 are arranged alternately around the circumference; Figure 1 and Figure 2 As shown, the shaving ring 3 is composed of a thick area 32 and a thin area 31 .
[0047] Preferably, the thick area 32 and the thin area 31 transition smoothly, and the thickness transitions gradually from the thin area 31 to the thick area 32 to avoid forming obvious steps, so as to improve skin feel.
[0048] The shaving track 2 is provided with more than two inside and outside, such as Figure 1-3 In the embodiment shown, the shaving rings 3 corresponding to two adjacent shaving tracks 2 are spaced apart; Figure 4 In the embodiment shown, the shaving rings 3 corresponding to two adjacent shaving tracks 2 are connected together, so that the top surface between the two shaving rings 3 is continuous and serves as a skin-contacting surface, providing a good skin feel.
[0049] Preferably, one side or both sides of the fixed cutting teeth 4 have sharp-angled cutting edges 42 to improve cutting sharpness.
[0050] Preferably, the blade net body 1 and its net top are formed by powder metallurgy, and the thin area 31, the thick area 32 and the fixed cutting teeth 4 are formed by powder metallurgy, which has a simple structure and a simple manufacturing process.
