[0031] The utility model provides the following technical solutions:

[0032] As attached Figure 1-6 As shown, the utility model discloses a multi-net static knife, including an outer ring static knife 1 and at least one inner ring static knife 2, wherein the inner ring static knife 2 and the outer ring static knife 1 are arranged in a concentric ring structure, and under the action of an external force, the outer ring static knife 1 and the inner ring static knife 2 can float downward in the axial direction relatively independently and automatically reset. Specifically, in this design, by arranging the outer ring static knife 1 and the inner ring static knife 2 in a concentric ring structure, and the outer ring static knife 1 and the inner ring static knife 2 floating on the driving source 6 are relatively independent, so that the comfort of shaving contacting the skin can be improved and the shaving efficiency can be improved.

[0033] Further, a static knife connection structure is provided between the inner ring static knife 2 and the outer ring static knife 1, and the static knife connection structure includes a static knife transmission part 3 provided on the outer ring side of the inner ring static knife 2 and a static knife transmission end 4 provided on the inner ring side of the outer ring static knife 1, a static knife transmission groove 31 is provided on the static knife transmission part 3, the bottom of the inner ring side of the outer ring static knife 1 presses the static knife transmission part 3, and the static knife transmission end 4 extends into the static knife transmission groove 31 to connect with the inner ring static knife 2. Specifically, in this embodiment, when the outer ring static knife 1 is forced to float downward, the static knife transmission end 4 on the outer ring static knife 1 moves downward in the static knife transmission groove 31, and will not drive the inner ring static knife 2 to float during the movement. When the inner ring static knife 2 is forced to float downward, the inner ring static knife 2 moves downward together through the static knife transmission part 3 and the static knife transmission groove 31, and at this time, the static knife transmission end 4 moves downward together in the static knife transmission groove 31, thereby driving the outer ring static knife 1 to float.

[0034] Furthermore, the outer ring side of the inner ring static knife 2 fits with the inner ring side of the outer ring static knife 1. Specifically, in this embodiment, the outer ring side of the inner ring static knife 2 fits tightly with the inner ring side of the outer ring static knife 1, ensuring the stability between the two and avoiding shaking or misalignment during use. This fitting design not only enhances the stability of the overall structure, but also helps to improve the accuracy and efficiency of shaving.

[0035] Furthermore, a gap is formed between the inner ring side of the inner ring static knife 2 and the outer ring side of the outer ring static knife 1, the inner ring static knife 2 and the outer ring static knife 1 are gap-matched, and the gap between the inner ring static knife and the outer ring static knife is less than 1 mm. Specifically, in this embodiment, the outer ring static knife 1 and the inner ring static knife 2 adopt a gap-matched structure, which can prevent hair from getting stuck, affecting the shaving experience and the cleaning effect after shaving.

[0036] Furthermore, the inner ring static blade 2 can be displaced axially upward under the action of an external force to be flush with the outer ring static blade 1. Specifically, in this embodiment, the inner ring static blade 2 has the ability to be displaced axially upward under the action of an external force, so that it can be flush with the outer ring static blade 1. This design enables the inner ring static blade 2 to adaptively adjust its position when encountering an uneven skin surface during shaving, and maintain a relatively consistent height with the outer ring static blade 1, thereby ensuring uniformity and comfort of shaving.

[0037] Furthermore, the inner circle static knife 2 and the outer circle static knife 1 are provided with an inner circle hair inlet pore 33 and an outer circle hair inlet pore 34, respectively, and the cross-sectional shapes of the inner circle hair inlet pore 33 and the outer circle hair inlet pore 34 are the same shape or different shapes. Specifically, the inner circle hair inlet pore 33 and the outer circle hair inlet pore 34 with different cross-sectional shapes can guide the hair in different directions when entering, thereby improving the efficiency of shaving. In addition, the asymmetric structure can also effectively prevent the hair from being blocked or entangled in the hair inlet pore, further improving the smoothness of shaving and user experience. Specifically, the inner circle hair inlet pore 33 is a shape such as a circle, a square, or a diamond, which is suitable for the introduction of short hair, and the outer circle hair inlet pore 35 can be a strip with a larger cross-sectional shape, which is suitable for the introduction of long hair.

[0038] Furthermore, the top surface of the outer ring static blade 1 is straight, convex or concave, and the top surface of the inner ring static blade 2 is straight, convex or concave. Specifically, in this embodiment, the top surfaces of the outer ring static blade 1 and the inner ring static blade 2 can be designed according to actual needs. For example, when the shaving efficiency needs to be improved, the top surface of the outer ring static blade 1 can be designed to be a convex arc shape to better fit the skin and capture hair; while the top surface of the inner ring static blade 2 can be designed to be straight to provide a stable shaving effect.

[0039] Furthermore, the arc directions of the top surfaces of the outer ring static blade 1 and the inner ring static blade 2 are the same and are continuous arc segments. Specifically, in this embodiment, the top surfaces of the outer ring static blade 1 and the inner ring static blade 2 are designed with continuous arc segments in the same direction. This design can ensure that during the shaving process, the static blade can better fit the curve of the skin surface, thereby improving the comfort and efficiency of shaving.
