Description

[Technical field]

[0001] The utility model relates to a circular blade net of a rotary shaver. [Background technology]

[0002] The circular blade net of the existing rotary shaver is usually required to have a strong structural strength and be able to resist deformation. Therefore, its manufacturing process is usually to first punch out a blank with a circular shaving track from a metal plate with a thickness of about 0.5 mm, then thin the shaving area, and open a hair feeding structure on the shaving track. The most commonly used hair feeding structure is to open a straight groove to form a straight groove type hair feeding hole. Generally, a straight groove is cut on the shaving track by rotating a grinding wheel. The straight groove cuts through the shaving track to form a hair feeding hole. The straight groove generally runs through the shaving track at the same time. The top and side surfaces of this structure of pores, when the top of the blade mesh moves against the skin, due to the characteristics of the skin, the skin is easy to squeeze into the blade mesh from the straight slot on the side, and move to the cutting area where the top of the shaving track cooperates with the moving knife, which has the risk of being cut. Therefore, a very thin grinding wheel is generally used to process the straight slot, and the slot width of the straight slot is usually designed to be very small, generally around 0.26mm, and the skin is blocked by the narrow slot width, so that the arch of the skin does not enter the blade mesh to ensure safety. However, the width of the straight slot is small, and the diameter of the short beard is about 0.1mm, which reduces the probability of the beard entering the shaving track through the straight slot and being shaved, and it takes repeated shaving to shave cleanly.

[0003] The utility model is made based on this purpose. [Contents of the utility model]

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figures 1 to 9 The circular blade net of the rotary shaver shown in the figure comprises a top wall 1 and a plurality of annular side walls 2, the circular blade net is provided with a plurality of groove-shaped hair inlet holes 3, the groove-shaped hair inlet holes 3 are distributed along a straight line L in the inner and outer directions, the groove-shaped hair inlet holes 3 pass through the top wall 1 and one or two of the side walls 2, the groove-shaped hair inlet holes 3 comprise a slit 31 and a wide groove 32, the slit 31 is formed on the side wall 2 and on the top wall 1 near the side wall 2, the wide groove 32 is formed in the middle part of the top wall 1 and is connected to the slit 31, and the width of the wide groove 32 is larger than that of the slit 31.

[0029] When shaving, the shaver is placed against the skin with the top wall 1 of the circular blade net. When the shaver moves, the narrow opening 31 can prevent the skin from squeezing into the groove-shaped hair entry holes 3. The wide grooves 32 on the top wall 1 can increase the effective hair entry area, thereby improving the hair entry efficiency and the hair cutting efficiency.

[0030] In order to improve the skin feel, the outer edge of the groove-shaped pore 3 is polished to form a smooth chamfer 30.

[0031] like Figures 1 to 7 As shown, there are more than two side walls 2 disposed inside and outside, wherein the two side walls 2 and the top wall 1 therebetween form a ring-shaped shaving track 4, and the interior of the shaving track 4 forms an inner track 5 for the movable knife to rotate.

[0032] like Figures 1 to 3 In one embodiment shown in the figure, the groove-shaped hair-entry hole 3 penetrates the top wall 1 and the inner and outer side walls 2 of the shaving track 4 at the same time, and a slit 31 is formed on the inner and outer side walls 2 and the top wall 1 near the inner and outer side walls 2. Looking down from the top, the wide groove 32 is a "()"-shaped structure connecting the inner and outer slits 31. The slit 31 and the wide groove 32 are distributed along the straight line L, and the structure is simple and easy to manufacture. Figure 4 As shown, during manufacturing, a straight groove can be firstly made on the mesh blank of the circular knife net to process the straight groove type inlet pores, and then the hole walls on both sides of the middle of the straight groove type inlet pores are reduced to make the hole walls concave, forming a bracket-shaped structure, and the production process is simple; after processing, the hole walls are concave to form an arc-shaped wall that evenly transitions from the gorge 31, and the hole wall reduction method can be mechanical processing, electrochemical corrosion or polishing. Of course, other processes can also be used to produce and process the circular knife net with a "()"-shaped structure of grooved inlet pores.

[0033] The smaller the width of the gorge 31, the better the safety, the larger the width of the wide groove, the larger the hair feeding area, but the larger the width of the wide groove 32, the lower the safety, so further, the width d of the gorge 31 is ≤ 0.26mm, the width w of the wide groove 32 at the widest position is ≤ 0.4mm, and the hair feeding efficiency is high. Preferably, the width w of the wide groove 32 at the widest position is between 0.28mm and 0.35mm, which increases the hair feeding area while ensuring safety and improves cutting efficiency.

[0034] like Figures 5 to 7 In another embodiment shown, the groove-type hair-entry hole 3 penetrates the top wall 1 and one of the side walls 2 of the shaving track 4 at the same time, and the groove-type hair-entry hole 3 extends from one end of the side wall 2 on the top wall 1 of the shaving track 4 to the middle of the shaving track 4. Looking down from the top, the gorge 31 and the wide groove 32 are distributed along the straight line L. The groove-type hair-entry hole 3 is a teardrop-shaped structure, that is, the groove-type hair-entry hole 3 has a terminal end on the top wall 1, and the wide groove 32 gradually increases in width from the position of the gorge 31 to the terminal end and then narrows to the terminal end. The top wall 1 has a terminal end, which has the effect of preventing the hair entering the wide groove 32 from escaping. Since the moving blade of the razor rotates at a high speed, it is beneficial to improve the shaving efficiency.

[0035] Preferably, on the same shaving track 4, the groove-shaped hair-entry holes 3 have two inner and outer circles, wherein the groove-shaped hair-entry holes 3 of the outer circle penetrate the top wall 1 and the outer side wall 2 of the shaving track 4 at the same time, while the groove-shaped hair-entry holes 3 of the inner circle penetrate the top wall 1 and the inner side wall 2 of the shaving track 4 at the same time, the groove-shaped hair-entry holes 3 of the outer circle and the groove-shaped hair-entry holes 3 of the inner circle are staggered, the groove-shaped hair-entry holes 3 of the outer circle terminate near the inner side wall 2 on the top wall 1 of the shaving track 4, while the groove-shaped hair-entry holes 3 of the inner circle terminate near the outer side wall 2 on the top wall 1 of the shaving track 4. The inner and outer circles of the groove-shaped hair-entry holes 3 facilitate the hair to enter from the inner and outer sides of the shaving track 4 through the gorge 31 of the inner and outer groove-shaped hair-entry holes 3, while increasing the number of the groove-shaped hair-entry holes 3.

[0036] Since two adjacent groove-shaped hair-feeding holes 3 on the same circle are separated by groove-shaped hair-feeding holes 3 on another circle, sufficient space is reserved between two adjacent groove-shaped hair-feeding holes 3 on the same circle. By utilizing this space, an outer trumpet hair-guiding opening 7 corresponding to the groove-shaped hair-feeding holes 3 and used for guiding hair into the groove-shaped hair-feeding holes 3 is provided at the turning point between the top wall 1 and the side wall 2 on the shaving track 4. Preferably, the outer trumpet hair-guiding opening 7 is a V-shaped opening inclined upward, and hair is guided through the outer trumpet hair-guiding opening 7 to further improve the hair-feeding efficiency.

[0037] like Figure 8In the embodiment shown, on the same shaving track 4, there are two types of slot-type hair inlet holes 3, wherein the first type of slot-type hair inlet holes 3a simultaneously penetrates the top wall 1 and the outer side wall 2 of the shaving track 4, and the first type of slot-type hair inlet holes 3a extends from one end of the outer side wall 2 on the top wall 1 of the shaving track 4 to the middle of the shaving track 4, and when viewed from the top, the first type of slot-type hair inlet holes 3a is a teardrop-shaped structure; while the second type of slot-type hair inlet holes 3b simultaneously penetrates the top wall 1 and the inner and outer side walls 2 of the shaving track 4, and the second type of slot-type hair inlet holes 3b form gorges 31 on the inner and outer side walls 2, and on the top wall 1 near the inner and outer side walls 2, respectively, and when viewed from the top, the wide groove 32 is a "()"-shaped structure connecting the inner and outer gorges 31, and the first type of slot-type hair inlet holes 3a and the second type of slot-type hair inlet holes 3b are alternately distributed. The groove-shaped inlet holes 3 divide the top wall 1 into a plurality of mesh strips 11. The mesh strips 11 need to have a certain width to ensure their strength. Figure 4 As shown, on the same shaving track, the smaller the radius of the circle, the smaller the width of the mesh strip at the corresponding position. The staggered distribution of the first slot-type feed holes 3a and the second slot-type feed holes 3b can effectively increase the number of slot-type feed holes, improve the strength of the mesh strip 11, and avoid the mesh strip 11 being too narrow at the position close to the inner wall 2.

[0038] like Fig. 9 In another embodiment shown, the side wall 2 has a top wall 1 which is a continuous dome. The side wall 2 and the top wall 1 form an inner cavity for the rotating movement of the movable knife. The groove-shaped feed holes 3 are distributed on the outer edge of the top wall 1. A circular hole 8 is provided on the top wall 1 on the inner side of the groove-shaped feed holes 3.
