[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0029] The rotary shaver heads on the market are basically flat, and the cutting grooves are mostly straight grooves. At the same time, the blade width is designed to be narrow, which cannot cover the cutting edge on the knife net well, resulting in low shaving efficiency and poor movement comfort.
[0030] In view of this, the utility model provides a cutter head assembly with a curved mesh cover, which is generally installed on the head of a shaving device and is used to fit the skin and cut hair. Figure 1-4 This is an embodiment of a cutter head assembly with a curved mesh cover provided by the utility model. Figure 1-4 The blade head assembly 100 with a curved mesh cover comprises a blade net 1 and a circular blade 2. The blade net 1 is also a curved mesh cover.
[0031] Specifically, the blade net 1 is disc-shaped, and an inner ring shaving track 11 and an outer ring shaving track 12 are formed on its surface. The inner ring shaving track 11 and the outer ring shaving track 12 are concentrically arranged and arched from the outer surface of the blade net 1, so that the inner and outer shaving tracks have arc surfaces. The inner and outer shaving tracks are provided with a plurality of holes for inserting beards. The circular knife 2 is rotatably arranged on one side of the inner surface of the blade net 1, and has a plurality of transverse blades 21 arranged near the inner surfaces of the inner ring shaving track 11 and the outer ring shaving track 12. The beards are shaved by the shearing action between the transverse blades 21 and the holes of the inner and outer shaving tracks.
[0032] In the technical solution of the utility model, the blade net 1 is provided with an arched and concentric inner ring shaving track 11 and outer ring shaving track 12. Such a structure can not only increase the shaving area and improve the shaving efficiency, but also facilitate movement and close contact during shaving, thereby improving shaving comfort.
[0033] To improve shaving efficiency, refer to Figure 1 and Figure 2 In one embodiment of the utility model, the width of the inner ring shaving track 11 is greater than the width of the outer ring shaving track 12. After the beard enters the outer ring shaving track 12 and is cut, the thicker beard enters the wide inner ring shaving track 11 again and can be well captured and then cut short. Since the shearing force of the circular knife 2 in the inner ring shaving track 11 is greater, it is easier to cut short the thicker beard. Such a design can not only increase the shaving area, but also improve the shaving efficiency.
[0034] See also Figure 1 and Figure 2 In one embodiment of the utility model, each transverse blade 21 is evenly distributed along the circumferential direction of the circular blade 2. In this embodiment, there are 6 transverse blades 21, and of course other numbers can be set, which can be distributed according to the radius of the shaving track. Each transverse blade 21 is located at the inner ring shaving track 11 and the outer ring shaving track 12, so that it can cut the beards in the inner and outer shaving tracks at the same time.
[0035] To facilitate the beard to enter the knife net 1, please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the holes on the blade net 1 include strip holes 1a and round holes 1b. When the shaver is used, whether it is inserted straight or moved, the beard can be well captured.
[0036] Further, to better utilize the inner ring shaving track 11, please refer to Figure 1 and Figure 2In one embodiment of the utility model, the strip holes 1a and the round holes 1b are alternately arranged and evenly distributed along the circumference of the inner ring shaving track 11. The round holes 1b are more likely to capture thicker beards when inserted directly, and the strip holes 1a are used to capture the beards that enter the inner ring shaving track 11 after being cut by the outer ring shaving track 12. Since the shearing force of the circular knife 2 on the inner ring shaving track 11 is greater, such a hole design of the inner ring shaving track 11 can better utilize the use area of the inner ring shaving track 11.
[0037] Further, in order to better utilize the outer ring shaving track 12, please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the strip holes 1a are evenly distributed in the circumferential direction of the outer ring shaving track 12. Since the width of the outer ring shaving track 12 is narrow and the shear force of the circular knife 2 on the outer ring shaving track 12 is large, it is not suitable to set the circular hole 1b. Here, only the strip holes 1a are provided to facilitate the short cutting of thin beards during movement.
[0038] To facilitate the cutting of the cross blade 21 and the strip hole 1a, please refer to Figure 1 and Figure 2 In one embodiment of the utility model, each strip hole 1a is obliquely arranged on the outer surface of the inner ring shaving track 11 and the outer ring shaving track 12, that is, it is offset relative to the radial direction. Since the blade edge of the transverse blade 21 extends in the radial direction, a suitable shearing angle can be provided between the obliquely arranged strip hole 1a and the transverse blade 21, and the angle can be between 10° and 20°.
[0039] See also Figure 3 and Figure 4 In one embodiment of the utility model, a mounting piece 2a is fixedly provided at the center of the circular knife 22, a rotating hole 22 is provided at the center of the mounting piece 2a toward one end of the knife net 11, a cylinder 13 matching the shape of the rotating hole 22 is provided at the center of the knife net 11, and the rotating hole 22 can rotate around the cylinder 13 to position the circular knife 2; the other end of the mounting piece 2a is connected to the rotating shaft of the driving motor to drive the circular knife 22 to rotate.
[0040] See also Figure 4 In one embodiment of the utility model, the circular knife 22 is in the shape of a disc, and each transverse blade 21 is formed integrally with the main body of the circular knife 22; that is, the blade of the transverse blade 21 is formed by cutting the main body of the circular knife 22, so that the base material can be effectively used to increase the strength and rigidity of the main body of the circular knife 22. In addition, the blade of the transverse blade 21 is widened, and its width is at least 50% wider than that of similar products, and the shearing efficiency is higher.
[0041] The utility model also proposes a shaver, which includes at least one of the above-mentioned blade head components 100 with curved mesh cover, which is commonly used in some double-head or triple-head shavers; it should be understood that the shaver also includes structures such as a motor, a power supply and a casing.
[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0043] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
