Abstract
Description
Technical Field
[0001] The utility model relates to a rotary shaver net with a large hair inlet area.
Background Art
[0002] For the shaver net of the existing rotary shaver, its hair inlet structure generally has two types: a groove-shaped hair inlet groove and a hole-shaped hair inlet hole. Among them, the hair inlet groove is usually cut out by a grinding wheel, and the hair inlet hole is usually punched out. From top to bottom, the sizes of the hair inlet groove or the hair inlet hole are generally the same or basically the same. The area corresponding to the upper port of the hair inlet groove or the hair inlet hole is the hair inlet area. In the area where the hair inlet groove is located, generally, the total hair inlet area of the hair inlet groove accounts for less than 50%, and the distance between the hair inlet holes is usually relatively large for convenient punching, and the proportion of its hair inlet area is smaller than that of the hair inlet groove. And the smaller the proportion of the total hair inlet area, the lower the hair inlet efficiency and cutting efficiency.
[0003] When shaving, the skin is generally attached to the top surface of the shaver net. The smaller the total hair inlet area, the larger the area pressing on the skin. As the shaver net moves on the skin, the hair is easily pressed down or crooked, and some crooked hair cannot stand up in time in the hair inlet groove to be cut, and it needs to be shaved repeatedly many times to be shaved clean.
[0004] The present utility model is made based on this situation.
Content of the Utility Model
[0005] The technical problem to be solved by the present utility model is to provide a rotary shaver net with a large hair inlet area, which has a simple structure, a large hair inlet area at the upper end inlet of the hair inlet groove or the hair inlet hole, is beneficial to increasing the proportion of the total hair inlet area, and improving the hair inlet efficiency and shaving efficiency.

Specific Embodiments
[0031] The following further describes the present utility model in conjunction with the accompanying drawings:
[0032] As Figures 1 to 8A rotary shaver net with a large beard-entering area is shown, which includes a rigid net body 1 of the shaver net. A shaving track 2 is provided on the net top 10 of the net body 1. A hair inlet groove 3 or a hair inlet pore 4 for hair to enter the shaving track 2 is provided on the net top 10 corresponding to the shaving track 2. Of course, a hair inlet groove 3 and a hair inlet pore 4 for hair to enter the shaving track 2 can also be provided on the net top 10 corresponding to the shaving track 2 at the same time. A plurality of pits 5 recessed downward from the top surface of the net top 10 are provided on the side walls of the hair inlet groove 3 and / or the hair inlet pore 4. One side of the pit 5 is integrated with the hair inlet groove 3 or the hair inlet pore 4, thereby expanding the beard-entering area of the upper end inlet of the hair inlet groove 3 or the hair inlet pore 4, making it easier for hair to enter the hair inlet groove 3 or the hair inlet pore 4 and improving the hair inlet efficiency.
[0033] In addition, the pit 5 is a local depression point provided at the upper end of the side wall of the hair inlet groove or the hair inlet pore. The pit 5 provides more space for the tilted beards to stand up so that they can be better cut, improving the cutting efficiency. And when shaving, when the net top moves on the skin, the skin will be squeezed downward and arched in the hair inlet groove or the hair inlet pore, and the pit 5 improves the undulation change of the skin so that the tilted beards can better stand up and enter the hair inlet groove 3 or the hair inlet pore 4 to be cut.
[0034] Preferably, as Figure 4 、 9 shown in 10, the pit 5 does not penetrate the net top 10 downward to prevent the skin from being squeezed into the shaving track 2 through the pit 5 and being cut.
[0035] Preferably, as Figures 1 - 6 shown in the embodiment, a hair inlet groove 3 is provided on the net top 10 corresponding to the shaving track 2. Pits 5 recessed downward from the top surface of the net top 10 are respectively provided on the left and right side walls of the same hair inlet groove 3, and the beard-entering area of the hair inlet groove 3 is large.
[0036] In a preferred embodiment, as Figures 1 - 3 and Figure 5 shown, the pits 5 on the left and right side walls of the same hair inlet groove 3 are opposite to each other left and right, so that the left and right pits 5 form a large opening conducive to the entry of the skin and beard hair.
[0037] In another preferred embodiment, as Figure 6As shown, the pits 5 on the left and right side walls of the same hair inlet groove 3 are arranged in a staggered manner, so as to avoid the insufficient structural strength of the mesh strip 30 between adjacent two hair inlet grooves 3 at the pits 5 and being easily broken, and also enable the skin to form a variety of different squeezing states and deformed arching states in the length direction of the hair inlet groove, so that the beard is more likely to stand up and slide into the hair inlet groove 3. Further, along the rotation direction of the moving cutter teeth 7, the pits 5 on the front side wall of the hair inlet groove 3 are arranged away from the middle of the shaving track 2, and the pits 5 on the rear side wall are arranged close to the middle of the shaving track 2.
[0038] Or, as Figures 7 - 8 shown in the embodiment, along the rotation direction of the moving cutter teeth 7, the front side wall of the hair inlet groove 3 is used to cooperate with the moving cutter teeth for cutting, and the pits 5 are arranged on the rear side wall of the hair inlet groove 3, so as to avoid the reduction of the strength of the front side wall and being easily dulled during the cutting use process.
[0039] Preferably, as Figure 4 shown, the material thickness of the mesh top 10 corresponding to the shaving track 2 is thin at the middle position of the shaving track 2 and becomes thicker towards both sides, and the pits 5 are arranged on both sides of the middle of the shaving track 2. The material thickness of the mesh top 10 is thin at the middle position of the shaving track 2 to improve the shaving cleanliness, and has thicker materials on both sides of the middle of the shaving track 2. The pits 5 are arranged at the thicker materials, which is beneficial to increasing the depth of the pits 5 concave downwards, and at the same time avoiding the insufficient structural strength of the mesh strip 30 between adjacent two hair inlet grooves 3 and being easily broken.
[0040] As Figures 1 - 3 and Figures 5 - 7 shown in the embodiment, the hair inlet groove 3 is a straight groove; or as Figure 8 shown in the embodiment, the hair inlet groove 3 is in a curved shape.
[0041] Preferably, as Figure 5 、 9 、10 shown, a chamfer R is provided at the upper end edge of the hair inlet groove 3 and / or the hair inlet pore 4 to improve the skin feel; a sharp blade 6 is provided at the lower end edge of the hair inlet groove 3 and / or the hair inlet pore 4 to improve the cutting sharpness.
[0042] Preferably, the cutter net body 1, the hair inlet groove 3 and / or the hair inlet pore 4 thereon, and the corresponding pits 5 are integrally injection molded by powder metallurgy, with a simple structure and being beneficial to production and manufacturing. In the prior art, the hair inlet groove is realized by grooving with a grinding wheel, and the hair inlet pore is realized by stamping. It is difficult to locally provide pits on the side wall of the hair inlet groove or the hair inlet pore, while the rotary shaver cutter net is integrally formed by powder metallurgy, which is convenient to locally form pits on the side wall of the hair inlet groove or the hair inlet pore.
[0043] For the powder metallurgy forming process, it includes the following steps: injecting a raw material with stainless steel powder through an injection molding machine to obtain a cutter net blank, the cutter net blank including a cutter net body, the cutter net body having an inner cavity with an opening facing downwards, an inlet hair groove and / or an inlet pore integrally formed on the mesh top of the cutter net body, and a pit on the side wall of the inlet hair groove and / or the inlet pore; putting the cutter net blank into a degreasing furnace for degreasing; putting the degreased cutter net blank into a sintering furnace for sintering; performing heat treatment hardening on the sintered cutter net blank; shaving off part of the material from the bottom of the mesh top of the cutter net body to form a shaving track for the rotary movement of the moving cutter teeth 7, so that the inlet hair groove and / or the inlet pore penetrate from top to bottom to the corresponding shaving track.
