Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the description of the specific embodiments is intended for purposes of illustration only and is not intended to limit the scope of the present disclosure.

A double-ring convex cambered surface ultra-large area shaver head comprises a head 1 and a cutter mesh 2 matched with the head.

As shown in fig. 1, the cutter head is provided with an inner ring cutter blade 1.1, an outer ring cutter blade 1.2, slag holes 1.3 and reinforcing ribs 1.4. The inner ring blade and the outer ring blade are arranged in an inner concentric manner, the inner ring blade is arranged circumferentially around the center of the cutter head, the cutting edge of the inner ring blade is arc-shaped, the outer ring blade is arranged outside the inner ring blade and also arranged circumferentially around the center of the cutter head, and the cutting edge of the outer ring blade is arc-shaped. Six inner ring blades and nine outer ring blades are arranged on the cutter head.

The outer ring blade is arranged at the edge of the cutter head, and is formed by bending, and the included angle between the outer ring blade and the plane of the cutter head is 40-70 degrees. The included angle between the inner ring blade and the plane of the cutter head is equal to the included angle between the outer ring blade and the plane of the cutter head, the included angle between the inner ring blade and the plane of the cutter head is 40-70 degrees, and the inner ring blade is formed by punching. When the inner ring blade breaks on the plane of the cutter head and turns up to be formed, a vacant hole site is formed at each broken position to serve as a slag-off hole, a slag-off hole is formed below the cutting edge of each inner ring blade, and shaved beard slag can be discharged downwards from the slag-off hole and cannot be accumulated on the cutter head. The reinforcing rib is arranged between the two adjacent inner ring blades and protrudes from the top surface of the cutter head and extends along the radial direction of the cutter head, so that the strength and rigidity of the cutter head can be enhanced, the deformation is reduced, the stability in use is improved, the size of the cutter head can be greatly increased, the requirements of shaving, shaving and light head are met, and the complexity of the whole structure and the production cost are reduced.

As shown in fig. 3, the cutter head is provided with a center piece. The center piece comprises a clamping ring 3, a base 4 and a spring 5. The clamping ring is fixed at the center of the cutter head, the base is hooked by the triangular hook to pull the clamping ring, and the spring is arranged between the clamp and the base. The center piece can adjust the error of the height and concentricity of the cutter head when the cutter head is installed on the whole machine.

The knife net is provided with an inner ring net 2.1 and an outer ring net 2.2. The inner ring network and the outer ring network are arranged inside and outside concentrically. The inner ring net is provided with a plurality of whisker feeding grooves which are circumferentially arranged around the center of the cutter net. The outer ring net is also provided with a plurality of whisker feeding grooves which are circumferentially arranged around the center of the cutter net. The whisker feeding grooves are V-shaped grooves, the large opening ends of the V-shaped grooves are positioned on the top surface of the cutter mesh, and the small opening ends of the V-shaped grooves are positioned on the bottom surface of the cutter mesh.

The inner ring net is in an upward arched arc shape (which is matched with the shape of the cutting edge of the inner ring cutting edge), the curvature radius of the top surface of the inner ring net (R1 in figure 10) is 2-6mm, and the curvature radius of the top surface of the inner ring net is slightly larger than that of the bottom surface. The outer ring net is in an upward arched arc shape (which is matched with the shape of the cutting edge of the outer ring cutting edge), the curvature radius of the top surface of the outer ring net (R2 in figure 10) is 2-6mm, and the curvature radius of the top surface of the outer ring net is slightly larger than that of the bottom surface. The shearing angle between the inner ring blade and the inner ring net and between the outer ring blade and the outer ring net is controlled between 15 and 30 degrees.

The arc-shaped inner ring net and the arc-shaped outer ring net are contacted with the face to generate a certain horn angle, so that the face is more faced, the beard is smoothly fed, and the shaving speed is high, so that the beard and the hair are effectively shaved thoroughly, the face is ensured to be clean and comfortable, the shaving time is greatly shortened, and the power consumption of a machine battery is saved; meanwhile, the strength and the rigidity of the cutter mesh are also increased, the service life of the cutter mesh is prolonged, and the size of the cutter mesh can be increased and matched with a cutter head with a large diameter for use.

Preferred embodiments of the present utility model are shown in the drawings. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
