Description

[Technical field]

[0001] The utility model relates to a side port protection piece and also relates to a reciprocating shaving head with the side port protection piece. [Background technology]

[0002] The existing reciprocating razor usually consists of a fixed blade fixed on a fixed blade support to form a fixed blade with a hollow structure at two ends, and the movable blade is located in the hollow structure and reciprocates between the two ends. The top surface of the fixed blade is used as the skin contact surface during shaving. Since the fixed blade is very thin, there is a risk of scratching the skin. Generally, a collar is put on the outside of it to block the exposed end, and the skin is contacted through the collar. The material thickness of the collar is much thicker than that of the fixed blade, usually more than one or two times. The skin is contacted through the end of the collar. The thicker the collar, the better the safety, so that the skin can be protected, such as the technical solution disclosed in the patent technology of a reciprocating electric razor head with multi-directional cutting, such as the announcement number CN209682252U. Since the collar protrudes from the outside of the fixed blade, when the top surface of the fixed blade is close to the skin for shaving, the collar forms a step protruding toward the skin at both ends of the fixed blade. The more obvious the step, the greater the impact on the skin feel. Therefore, while ensuring shaving safety and production feasibility, it is hoped that the thickness of the ring can be reduced. When shaving hair in concave parts, such as armpits and inner thighs, the end of the ring is easy to contact or squeeze the skin. The smaller the thickness of the ring, the more obvious the stimulation of the end of the ring on the skin. This makes it difficult to achieve a good balance between shaving safety and the skin feel of the top and end surfaces. The purpose of the utility model is to provide a technical solution with good safety and comfortable skin feel. [Contents of the utility model]

[0034] like Figures 1 to 3 A side port protection member 1 is shown, which is integrally formed of metal, and includes an end cover top wall 101, and end cover side walls 102 bent downward from the end cover top wall 101 to the left and right sides, the end cover top wall 101 and the end cover side walls 102 form a connecting port 103, and the end cover top wall 101 is provided with a downward edging 104 on the edge of one end, and a chamfer 106 is provided between the end cover top wall 101 and the edging 104.

[0035] The edging 104 extends downward from the end cover top wall 101 to form a wall surrounding the bottom of the end cover top wall 101, and the lower end surface 1041 of the edging 104 faces downward. When the end cover top wall 101 moves against the skin, the lower end surface 1041 of the edging 104 is avoided from facing the skin. The height d of the side port protection piece 1 at the end where the edging is located, that is, the height from the lower end surface 1041 of the edging to the top surface of the end cover top wall 101, is greater than the material thickness of the end cover top wall 101. Therefore, the height d of the side port protection piece 1 at the end where the edging is located can be controlled by controlling the depth of the edging. When the end where the edging is located of the side port protection piece 1 contacts the skin, the stimulation to the skin is small, and a chamfer 106 is provided between the end cover top wall 101 and the edging 104, which can provide a smooth feeling when contacting the skin. The hemming improves the skin feel of the hemmed end of the side port protection member 1, so the material thickness of the end cover top wall 101 can be reduced, such as using a metal material with a thickness of less than 0.4 mm to manufacture the side port protection member 1, preferably a material with a thickness of between 0.15 mm and 0.3 mm, such as Figures 8 to 11As shown, when the side port protection member 1 is put on the outer side of the end of the fixed blade of the reciprocating shaver head with the connecting port 103, the step formed by the protrusion of the end cover top wall 101 on the top surface of the fixed blade will become smaller, reducing the impact on the skin feel; wherein the edging 104 is located on the outer side of the end of the fixed blade, the fixed blade on the top of the fixed blade is shielded from the end surface, preventing the fixed blade from contacting the skin during shaving, and having good safety.

[0036] The side port protection member 1 has a smooth chamfer 108 between the surface where the metal material thickness is located and other outer surfaces. The smooth chamfer 108 can be obtained by polishing the product to eliminate the corners after stamping.

The end cover top wall 101 is provided with an end of a edging 104 extending outward from the outside of the end cover side wall 102. The edging 104 is provided with arc-shaped edges 105 bent toward the end cover side wall 102 at both ends. The arc-shaped edges 105 make a smooth transition between the edging 104 and the end cover side wall 102, thereby improving the skin feel of the outer side surrounded by the edging 104 and the end cover side wall 102.

[0038] The left and right ends of the edging 104 are respectively connected to the left and right end cover side walls 102. On the side of the side port protection component 1, the edging 104 is connected to the upper part of the end cover side wall 102 to form a whole. It has a simple structure and good strength. The top surface and the outer surface of the side port protection component 1 are smoothly connected to form a whole, which improves the skin feel.
