[0014] Figure 3 is Figure 1 an enlarged view of part A of

[0015] Figure 4 is a schematic structural diagram of Embodiment 2 of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Embodiment 1, as Figures 1 - 3 shown, a multi-edge cutter head for a self-help hair clipper includes a moving blade 100 and a stationary blade 200. Both the moving blade 100 and the stationary blade 200 are circular ring structures. The moving blade 100 and the stationary blade 200 both have a center of a circle, and the centers of the moving blade 100 and the stationary blade 200 coincide. An annular toothed cutting edge a is provided on the outer rings of the moving blade 100 and the stationary blade 200 with the center of the circle as the center point. After the moving blade 100 and the stationary blade 200 are assembled, a cavity is formed. An annular cutter head 300 is provided in the cavity with the center of the circle as the center point. The stationary blade 200 is provided with mesh holes 210 evenly distributed with the center of the circle as the center point. The working principle of hair-cutting is the same as that of a traditional hair clipper, that is, the moving blade 100 and the stationary blade 200 cooperate to achieve hair-cutting. The advantage of setting multiple cutter heads is that when cutting hair, multiple cutter heads can fully contact the hair, which can effectively improve the hair-cutting efficiency and the neatness of hair-cutting.

[0017] An annular toothed cutting edge a is provided on the outer rings of the moving blade 100 and the stationary blade 200. In this embodiment, a matching annular toothed cutting edge a is provided on the outer rings of the moving blade 100 and the stationary blade 200.

[0018] The moving blade 100 has an assembly hole 110 for assembling with the annular cutter head 300. The annular cutter head 300 has an assembly post 310 adapted to the assembly hole 110. The annular cutter head 300 passes through the assembly hole 110 of the moving blade 100 through the assembly post 310 and is connected to the drive assembly of the hair clipper. The moving blade 100 and the annular cutter head 300 move synchronously. The assembly structure of the moving blade 100, the annular cutter head 300 and the drive assembly of the hair clipper is basically the same as that of the traditional hair clipper, and will not be elaborated here too much.

[0019] The stationary blade 200 and the moving blade 100 are arranged in an up-and-down distribution structure. The outer diameter of the stationary blade 200 is larger than that of the moving blade 100, and the inner diameter of the stationary blade 200 is smaller than that of the moving blade 100. This solution is more convenient for processing and assembly, and this solution is preferably adopted.

[0020] The inner ring side wall of the stationary blade 200 is provided with a bayonet 220 for fixedly assembling with the hair clipper. The moving blade 100 has a travel slot 120 through which a bolt passes. The travel slot 120 is an arc-shaped long slot that fits the annular cutter body, mainly used to limit the rotation travel of the moving blade 100.

[0021] Arc-shaped bosses 230 are provided at the bottom ends of the annular tooth-shaped cutting edges a of the stationary blade 200. The function of the arc-shaped bosses is that they will not scratch the skin during hair cutting. That is, when the hair clipper is pushed on the scalp, the arc-shaped bosses 230 at the end of the cutter head first contact the scalp, avoiding the tooth-shaped knife tips from scratching the scalp.

[0022] Embodiment 2, as Figure 4 shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, annular tooth-shaped cutting edges a are provided on the inner rings of the moving blade 100 and the stationary blade 200.

[0023] Embodiment 3, the difference between this embodiment and Embodiments 1 and 2 is that in this embodiment, annular tooth-shaped cutting edges a are provided on both the inner rings and the outer rings of the moving blade 100 and the stationary blade 200.

[0024] The present utility model provides a multi-edge cutter head for a self-service hair clipper. By changing the traditional single-edge cutter head to a multi-edge cutter head, when in use, the contact range between the cutter head and the hair is larger. The inner or outer cutter head is convenient for cutting long hair, while the annular cutter head, that is, the middle net cutter, is convenient for cutting short hair and hair roots. It is more convenient to use, improves the hair cutting efficiency and the neatness of hair cutting, and is convenient and fast to use, and is suitable for the elderly and people who need to cut short hair or shave their heads.

[0025] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, simple modifications and substitutions made by ordinary technical personnel in the art are within the protection scope of the present utility model.
