Description

Technical Field

[0001] This utility model relates to the field of hair trimming equipment technology, specifically to a tool for trimming side hair. Background Technology

[0002] In existing technologies, most blades are unable to efficiently trim the edges and corners of the ears when trimming hair, resulting in incomplete hair trimming. Summary of the Invention

[0003] In view of this, the present invention provides a tool for trimming side hair.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A tool for trimming side hair includes a moving blade, a stationary blade, and an eccentric wheel. The eccentric wheel is connected to the moving blade. The moving blade has a plurality of spaced-apart moving blade teeth, and the stationary blade has a plurality of spaced-apart stationary blade teeth. The eccentric wheel has an eccentricity C. The shortest distance between the moving blade teeth on one side edge of the moving blade and the stationary blade teeth on the same side edge of the stationary blade is B, where C ≥ B.

[0005] Preferably, the shortest distance B between the stationary cutter teeth is equal to the eccentricity C plus (0-1mm).

[0006] Preferably, the shortest distance between the edge of the moving blade on one side and the edge of the stationary blade on the same side is D, where D ≤ 1 mm.

[0007] Preferably, the distance from the tooth wall on one side edge of the stationary cutter away from the center of the stationary cutter to the same side edge of the stationary cutter is A, and the straight-line distance between the center lines of two adjacent stationary cutter teeth is G, wherein A = 1G~2G.

[0008] Preferably, the moving cutter tooth has a moving cutter tooth tip, the stationary cutter tooth has a stationary cutter tooth tip, and the shortest distance between the side edge of the moving cutter tooth tip away from the adjacent moving cutter tooth and the side edge of the stationary cutter tooth tip away from the adjacent stationary cutter tooth is F, wherein F ≥ 0 mm.

[0009] The beneficial effects of this utility model are as follows: by setting the shortest distance B between the moving blade teeth on one side edge of the moving blade and the stationary blade teeth on the same side edge of the stationary blade to be less than or equal to the eccentricity C of the eccentric wheel, since side hair is often difficult to trim, this design allows the blade to fit more closely to the skin during trimming, trimming the hair more cleanly, reducing trimming dead angles, and improving the user experience.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] The present invention will now be further described with reference to the accompanying drawings.

[0014] This utility model provides the following technical solution: As attached Figure 1-3 As shown, this utility model discloses a tool for trimming side hair, including a movable blade 1, a stationary blade 2, and an eccentric wheel 3. The eccentric wheel 3 is connected to the movable blade 1. The movable blade 1 has a plurality of spaced movable blade teeth 4, and the stationary blade 2 has a plurality of spaced stationary blade teeth 5. The eccentric wheel 3 has an eccentricity C. The shortest distance B between the movable blade teeth 4 on one side edge of the movable blade 1 and the stationary blade teeth 5 on the same side edge of the stationary blade 2 is defined as C ≥ B. Specifically, in this design, by setting the shortest distance B between the movable blade teeth 4 on one side edge of the movable blade 1 and the stationary blade teeth 5 on the same side edge of the stationary blade 2 to be less than or equal to the eccentricity C of the eccentric wheel 3, since side hair is often difficult to trim, this design allows the tool to fit more closely to the skin during trimming, resulting in cleaner hair trimming, reducing trimming blind spots, and improving the user experience.

[0015] Furthermore, the shortest distance B between the stationary blade teeth 5 is equal to the eccentricity C plus (0-1mm). Specifically, in this embodiment, by setting the shortest distance B between the stationary blade teeth 5 to be equal to the eccentricity C plus 0-1mm, the edge of the moving blade 1 can be made infinitely close to the edge of the stationary blade 2, so that when the blade edge cuts hair, it can reach the shortest edge. This design allows the moving blade teeth 4 to cooperate more closely with the stationary blade teeth 5 during operation, thereby achieving higher efficiency in cutting hair, especially when trimming hard-to-reach areas such as side corners, significantly improving the trimming effect, making the hair trimmed more thoroughly, while reducing skin irritation and enhancing user comfort.

[0016] Furthermore, the minimum distance between one edge of the moving blade 1 and the same edge of the stationary blade 2 is D, where D ≤ 1mm. Specifically, in this embodiment, by setting the distance D between one edge of the moving blade 1 and the same edge of the stationary blade 2 to less than or equal to 1mm, the fit and trimming effect of the blades when trimming side hair can be further ensured. This design makes the gap between the moving blade 1 and the stationary blade 2 smaller, reducing the possibility of hair escaping, thereby improving the accuracy and efficiency of trimming.

[0017] Furthermore, the distance from the side wall of the stationary blade 5 away from the center of the stationary blade 2 to the same side edge of the stationary blade 2 is A, and the straight-line distance between the center lines of two adjacent stationary blade teeth 5 is G, where A = 1G~2G. Specifically, in this embodiment, by setting the distance A from the side wall of the stationary blade tooth 5 away from the center of the stationary blade 2 to the same side edge of the stationary blade 2 to 1 to 2 times the straight-line distance G between the center lines of two adjacent stationary blade teeth 5, it can be ensured that the moving blade 1 cooperates more harmoniously with the stationary blade 2 during operation. When the unilateral running distance of the moving blade tooth 4 is between 1 and 2 times the distance of the stationary blade tooth 5, the best shaving effect can be achieved. This design not only improves trimming efficiency but also ensures the uniformity and comfort of trimming, avoiding unnecessary irritation to the skin caused by uneven shaving force.

[0018] Furthermore, the movable blade 4 has a movable blade tip 6, and the stationary blade 5 has a stationary blade tip 7. The shortest distance F between the edge of the movable blade tip 6 away from the adjacent movable blade 4 and the edge of the stationary blade tip 7 away from the adjacent stationary blade 5 is ≥ 0 mm. Specifically, in this embodiment, by setting the shortest distance F between the edge of the movable blade tip 6 away from the adjacent movable blade 4 and the edge of the stationary blade tip 7 away from the adjacent stationary blade 5 to be greater than or equal to 0 mm, the tightness of the movable blade 4 and the stationary blade 5 during engagement can be further ensured. When F is 0 mm, the movable blade tip 6 and the stationary blade tip 7 have almost no gap in their engagement. This design maximizes the use of the blade's cutting edge, improving trimming efficiency and accuracy. Simultaneously, since trimming side hair often requires close contact with the skin, this design also reduces unnecessary skin irritation and improves user comfort.

[0019] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
