Description

TECHNICAL FIELD

[0001] The utility model relates to a razor screen, especially a three-ring concave screen of an electric shaver. BACKGROUND

[0002] CN215968887U discloses an electric shaver screen, which comprises an inner ring and an outer ring coaxially arranged on the end face of the screen body; the inner ring and the outer ring are both formed by regularly arranging a plurality of straight grooves, and are both inwardly concave inner arc surfaces; a middle ring is further arranged between the inner ring and the outer ring, and the middle ring is formed by regularly arranging a plurality of harrow-shaped grooves; the harrow-shaped grooves are arranged at equal intervals between every two adjacent harrow-shaped grooves. The screen should be able to improve the shaving efficiency under the cooperation of the corresponding shaver head, and has a trimming function to meet the needs of people. The deficiency is that the trimming function and trimming efficiency need to be improved. SUMMARY

[0003] The utility model aims at overcoming the deficiency of the above background technology, and provides a three-ring concave screen of an electric shaver, which can quickly and efficiently shave and cut hair under the cooperation of the corresponding shaver head.

[0004] The technical scheme provided by the utility model is as follows:

[0005] A three-ring concave screen of an electric shaver, which comprises an outer ring and an inner ring coaxially arranged on the end face of the screen, and the outer ring and the inner ring are both formed by regularly arranging a plurality of straight grooves in a ring shape; characterized in that: a middle ring is coaxially arranged between the outer ring and the inner ring, and the middle ring comprises a plurality of bidirectional harrow-shaped grooves regularly arranged in a ring shape, and a plurality of harrow tooth grooves on each bidirectional harrow-shaped groove respectively extend towards the inner diameter direction and the outer diameter direction of the screen.

[0006] Every two adjacent bidirectional harrow-shaped grooves are arranged at equal distances.

[0007] The screen is in the shape of a concave spherical surface, and the middle ring is located on the concave spherical surface.

[0008] The outer ring and the inner ring are also located on the concave spherical surface.

[0009] The utility model has the beneficial effects that: since a plurality of bidirectional harrow-shaped grooves regularly arranged in a ring shape are arranged between the inner ring and the outer ring, the hair and the hair that have not entered the inner ring and the outer ring can all quickly enter the harrow tooth grooves of the bidirectional harrow-shaped grooves for shaving; the outer harrow tooth has a protection function, which can effectively prevent the raised skin tissue (such as acne, sarcoma, etc.) from entering the screen to be cut; in addition to the shaving function of the inner ring and the outer ring, the shaving capacity, the shaving efficiency and the use safety of the utility model are obviously improved, the shaving time is correspondingly reduced, and the cheeks after use are cleaner and more thorough.

[0015] The utility model will be further explained in connection with the embodiment shown in the drawing.

[0016] The three-ring concave cutter net of the electric shaver shown in the drawing, including outer ring 1 and inner ring 4 arranged coaxially at the cutter net end face, the outer ring is formed by arranging multiple straight grooves into annular, and the inner ring is also formed by arranging multiple straight grooves into annular; this is similar to the existing cutter net of the electric shaver.

[0017] The improvement of the utility model: still coaxially arrange a middle ring 2 between the outer ring and the inner ring, the middle ring includes several bidirectional nail harrow grooves 3 arranged into annular, all bidirectional nail harrow groove center lines 3-1 are at the same circumferential position, and several harrow tooth grooves on each bidirectional nail harrow groove all respectively extend towards the inner diameter direction and the outer diameter direction of the cutter net.

[0018] Further, the distance between every two adjacent bidirectional nail harrow grooves is equal.

[0019] Further, the cutter net is concave spherical, and the middle ring is located on the concave spherical surface.

[0020] The outer ring and the inner ring are also located on the concave spherical surface.

[0021] The utility model discloses when using, the razor with the knife net reciprocatingly moves on the user's cheek, the part beard and hair not entering the outer ring and the inner ring can be easily inserted in the rake tooth slot of bidirectional nail rake slot in the middle ring, thereby being shaved by the matched cutter head, and the reciprocating direction of razor always can be close to the vertical direction of the center line of at least three bidirectional nail rake tooth slots, so that every movement of razor is favorable for beard and hair to enter the rake tooth slot of bidirectional nail rake slot from the outer diameter direction or the inner diameter direction of the knife net, and moreover, the longer and denser hair also easily enters the rake tooth slot of bidirectional nail rake slot and is cut, and the nail rake tooth of outside has the protection function, can effectively prevent the raised skin tissue (such as pimple, sarcoma etc.) from entering the knife net and being cut, thereby the shaving efficiency and use safety are improved obviously. The middle ring, the outer ring and the inner ring are at the concave spherical surface, improve the adhesion with human cheek, have the characteristics of good skin moistening feeling, comfortable face sticking, also increase the net surface strength, prolong the service life.
