Abstract

The utility model relates to a shaving head assembly of a rotary type electric shaver. A foil of an existing rotary type dual-ring shaving head is mainly formed by conducting upward and downward bending multiple times, coaxiality accuracy of a plurality of tools distributed on the same annular structure of the foil is hardly ensured, and therefore the phenomenon that the foil and a foil body are matched poorly is easily caused. The shaving head assembly comprises a shaving head foil and a foil body. The foil body is composed of an inner-ring foil main body and an outer-ring foil main body, wherein the inner-ring foil main body and the outer-ring foil main body are coaxial with each other and isolated through an isolation ring. The shaving head assembly is characterized in that a plurality of rectangular beard entering holes are formed in the outer-ring foil main body and the inner-ring foil main body, and annular concave faces are formed in the inner-ring foil main body and the outer-ring foil main body respectively. According to the shaving head assembly, the coaxiality of multiple tools on the annular structure can be effectively controlled, consistency of running tracks is high when the tools work, the service life of the tools can be prolonged, the matching degree between the foil and the foil body is increased, sharpness is better, and sound consistency is higher.

Description

Shaving head assembly of a rotary electric shaver

technical field

The utility model relates to a shaving head assembly of a rotary electric shaver.

Background technique

The blades of the existing rotary double-ring shaving heads are mostly bent downwards and upwards. It is difficult to guarantee the coaxiality accuracy of multiple knives distributed on the same ring structure on the blade, which will easily lead to the cooperation between the blade and the knife net. Bad, the sharpness and sound quality of the razor are not good, and the cutting edge is also easy to wear, which reduces the service life of the shaving head. However, the existing blade structure is obtained by bending downwards and upwards in multiple ways, which requires more raw materials, lower material utilization rate, and serious waste of materials, which is not conducive to energy saving and environmental protection. Knives are single ply and will leave residue after shaving. At the same time, the knife net is thicker due to its strength, and it is easy to have residue after shaving.

Utility model content

The purpose of the utility model is to provide a rotary electric shaver shaving head assembly, thereby increasing the strength of the cutter, prolonging the life and improving the overall performance of the shaver.

For this reason, the utility model adopts the following technical solutions: a rotary electric shaver shaving head assembly, including a razor blade and a knife net, and the knife net is composed of two coaxial inner ring knife nets and The outer ring knife net is composed of the inner ring knife net and the outer ring knife net separated by an isolation ring. It is characterized in that the outer ring knife net and the outer ring knife net have a plurality of rectangular beard holes. Both the knife net and the outer ring knife net form an annular concave surface.

The razor blade includes two sets of coaxial inner ring cutters and outer ring cutters arranged on the base of the main blade, and the inner ring cutter is formed by secondary bending after being cut from the base.

The bottom of the main blade base is provided with an auxiliary blade, and the periphery of the auxiliary blade is provided with an elastic auxiliary tool; the auxiliary tool is arranged at the front end of the working part when the outer ring tool of the main blade rotates, and the auxiliary tool forms an included angle with the outer ring tool of the main blade. , the auxiliary tool rebounds after touching the beard and then touches the outer ring tool and then lifts up. After the auxiliary blade is assembled, it has a certain preloading force. Before the main knife shaves, the auxiliary blade can lift the beard under the action of the preloading force. After shaving, the skin elasticity will pull the stubble back into the skin, and shave For a cleaner, improved shave.

The lower part of the auxiliary tool is integrally connected with the base, the base is arranged obliquely downward, and the auxiliary tool is arranged obliquely relative to the outer ring cutter.

The outer ring cutter is connected to the base of the main blade through a bending arm, and a bayonet is formed on the auxiliary cutter, and the bayonet is sleeved on the bending wall.

The lower part of the base of the main blade is provided with a reinforced base, and the reinforced base has a tooth-shaped structure with upper and lower layers.

The center of the knife net is provided with a cylinder for cooperating with the knife.

The utility model has the following advantages: 1. The inner ring tool is formed by double upward bending, which can effectively control the coaxiality of multiple tools on the ring structure, so that the running track consistency of the tool is relatively high. It can increase the service life of the tool, improve the matching degree of the blade and the knife net, the sharpness is better, and the sound consistency is higher; 2. The inner ring tool of the blade is directly cut from the base and then bent upwards to form, without punching the tool first Cut out and then bend, this solution can effectively enhance the strength of the matrix; 3. An auxiliary blade is added to the outer ring of the blade, and the auxiliary blade pulls the beard to the outside of the skin, and then the blade cuts the beard. The elasticity of the skin pulls the stubble back into the skin, making the shave cleaner and improving the shaving effect; 4. Arc-shaped arc grooves are processed on the working surface of the knife net to reduce the thickness of the working surface of the knife net.

specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.

As shown in Figure 1-4, a rotary electric shaver shaving head assembly includes a razor blade and a knife net, and the knife net consists of two coaxial inner ring knife nets 12 and outer ring knife nets 13 Composition, the inner ring knife net 12 and the outer ring knife net 13 are separated by the isolation ring 11, there are a plurality of rectangular beard inlet holes 14 on the inner ring knife net 12 and the outer ring knife net 13, the inner ring knife net 12 and the outer ring knife net 13 A ring-shaped concave surface 15 is formed on the outer ring knife screen 13 .

The razor blade includes two sets of coaxial inner ring cutters and outer ring cutters arranged on the base of the main blade, and the inner ring cutter is formed by secondary bending after cutting from the base. The bottom of the main blade base 1 is provided with an auxiliary blade, and the periphery of the auxiliary blade is provided with an elastic auxiliary tool 4; horn. The bottom of the auxiliary cutter 4 is integrally connected with the negative film 3, the negative film 3 is arranged obliquely downward, and the auxiliary cutter 4 is arranged obliquely relative to the outer ring cutter 5. The outer ring cutter 5 is connected to the main blade base 1 through a bending arm 6 , a bayonet is formed on the auxiliary cutter 4 , and the bayonet 4 is set on the bending wall 6 . The inner ring cutter 2 is formed by secondary bending after being cut from the base 1 . The bottom of main blade base 1 is provided with reinforcing base 8, and reinforcing base 8 is the tooth-shaped structure of upper and lower layers, and the middle part of reinforcing base 8 is provided with the plastic part 7 that cooperates with knife net.

When shaving, the counseling cutter is blocked by the beard to retreat, and then blocked by the main knife blade to rise, so that the beard is pulled into the knife net, and the shave is more thorough without residue. The knife net consists of a series of elongated gaps forming two rings and small concave cylinders. There are arc-shaped grooves on the rings. Beards enter the knife net from the gaps and shave during the rotation of the knife. , because of the groove, the shaving part is closer to the root of the beard, the beard left after shaving is shorter, and the shave is cleaner. Small cylinders are used for assembly with tools.

It should be pointed out that the above-mentioned embodiment is only limited to the description of the embodiment, but the utility model is not limited to the above-mentioned way, and those skilled in the art can conveniently make modifications without departing from the scope of the utility model. Therefore, the scope of the present invention should include the maximum scope of the principles and new features disclosed in the present invention.
