In addition, the first knife foot 6, the second knife foot 7 and the third knife foot 8 are all provided with cutting grooves 9, which can enhance the cutting ability of the knife foot and better capture and cut off the beard during the shaving process.

[0026] The utility model also has a first positioning groove 10 on the upper cutter disc 1 and a second positioning groove 11 on the lower cutter disc 2. The arrangement of these positioning grooves helps to ensure accurate alignment of the upper cutter disc 1 and the lower cutter disc 2 during assembly, thereby improving assembly accuracy and structural stability.

[0027] according to Figure 4 As shown, a first through hole 12 is provided at the center of the blade disc, and a second through hole 13 is provided at the center of the lower blade disc 2. The diameter of the first through hole 12 is smaller than that of the second through hole 13. The mounting shaft 3 is mounted in the first through hole 12 and the second through hole 13. An annular groove 14 is provided on the mounting shaft 3, and the edge of the second through hole 13 is clamped in the annular groove 14, thereby ensuring the stable connection between the mounting shaft 3 and the lower blade disc 2. A first convex rib 15 is also provided on the mounting shaft 3, and a first groove 16 is provided on the upper blade disc 1. The first convex rib 15 is inserted into the first groove 16, thereby further fixing the position of the upper blade disc 1. A second convex rib 17 is provided in the annular groove 14, and a second groove 18 is provided on the lower blade disc 2. The second convex rib 17 is inserted into the second groove 18, thereby further fixing the position of the lower blade disc 2.

[0028] The angles between the first blade foot 6, the second blade foot 7 and the upper blade disc 1 are 50°-55°, and the angle between the third blade foot 8 and the lower blade disc 2 is 50°-55°, which can effectively improve the shaving efficiency, reduce the pulling and irritation to the skin, and improve the comfort of shaving.

[0029] The utility model discloses a shaver, comprising a body and a cutter head arranged on the body, the cutter head comprising a base and a shell arranged on the base, a double-layer three-ring movable cutter is arranged in the shell, a cutter net assembly on a cutter net frame comprises a first annular end face and a second annular end face which are concentric, wherein the diameter of the first annular end face is smaller than the second annular end face, first shaving grooves are sequentially distributed on the first annular end face, second shaving grooves are sequentially distributed on the second annular end face, a first cutter foot 6 and a second cutter foot 7 are arranged corresponding to the first shaving groove, and a third cutter foot 8 is arranged corresponding to the second shaving groove. Such a structure ensures that the shaver can efficiently capture and cut beards of different lengths and directions during use, thereby achieving a clean shaving effect.

[0030] When assembling the utility model, align the upper cutter disc 1 and the lower cutter disc 2 so that the first through hole 12 and the second through hole 13 overlap, insert the installation shaft 3 into the first through hole 12 and the second through hole 13, ensure that the annular groove 14 of the installation shaft 3 is clamped on the edge of the second through hole 13, so that the upper cutter disc 1 and the lower cutter disc 2 are firmly connected, ensure that the first convex rib 15 on the installation shaft 3 is inserted into the first groove 16 on the upper cutter disc 1 to fix the position of the upper cutter disc 1, and ensure that the second convex rib 17 in the annular groove 14 is inserted into the second groove 18 on the lower cutter disc 2 to fix the position of the lower cutter disc 2. Put the assembled double-layer three-ring movable knife into the housing to ensure that the various parts of the movable knife can move freely and will not interfere with each other. Install the knife net frame on the housing to ensure that the knife net frame is firmly fixed. Install the knife net assembly on the knife net frame to ensure that the first annular end face and the second annular end face are aligned with the positions of the first knife foot 6, the second knife foot 7 and the third knife foot 8 respectively. Install the assembled shell onto the base, ensure that the shell is firmly connected to the base and not loose, and finally install the assembled cutter head onto the body of the shaver. When in use, when the shaver contacts the skin, the shaving grooves on the first annular end face and the second annular end face of the cutter net assembly will capture the beard, the first blade foot 6 and the second blade foot 7 on the upper cutter disc 1 will rotate under the corresponding first shaving groove to cut the beard on the first annular end face, and the third blade foot 8 on the lower cutter disc 2 will move under the corresponding second shaving groove to cut the beard on the second annular end face. The precise coordination between the blade and the cutter net ensures that the beard can be cut efficiently and cleanly without causing damage to the skin.
