[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] In order to better describe and illustrate the embodiments of the present application, reference may be made to one or more drawings, but the additional details or examples used to describe the drawings should not be considered as limiting the scope of the utility model creation of the present application, any of the currently described embodiments or preferred methods.

[0026] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" are based on the positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention. They do not indicate that the device referred to must have a specific direction or operate in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0027] 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.

[0028] The blade and blade holder of the razors currently on the market are assembled and disassembled by magnetic attraction. However, the normal magnet-to-magnet attraction will produce a relatively strong magnetic attraction force on the moving blade in the blade head, which will easily cause the moving blade to deviate when rotating, resulting in an increase in the load during shaving, thereby increasing the current of the razor and reducing the endurance of the razor.

[0029] In view of this, the utility model provides a magnetic fixing structure of a shaver. Figure 1-4 This is an embodiment of the magnetic fixing structure of the shaver provided by the utility model. Figure 1-4 The magnetic fixing structure 100 of the shaver includes a mounting base 1, a magnet 2, a cutter head 3 and an iron part 4.

[0030] Specifically, the mounting seat 1 is arranged on the shaver body. For a single-head, double-head or triple-head shaver, the mounting seat 1 is also set to a corresponding number. Each mounting seat 1 is provided with a plurality of mounting grooves 11 for mounting each magnet 2 by bonding or interference fit. The cutter head 3 is mounted on the mounting seat 1 by magnetic attraction. The cutter head 3 includes an inner bracket 31 and an outer bracket 32 ​​connected to each other. A rotatable circular knife 33 is mounted on the inner bracket 31. The outer bracket 32 ​​has a circular opening 322. A mesh cover 34 is installed in the opening 322. When the beard extends into the mesh cover 34, the rotating circular knife 33 is matched to achieve shearing. An iron piece 4 is arranged below the inner bracket 31 and is arranged corresponding to the magnet 2. When the cutter head 3 is installed, the iron piece 4 at the bottom thereof is aligned with the magnet 2 on the mounting seat 1. Similarly, when disassembling, it is only necessary to remove the magnetic attraction effect.

[0031] It should be noted that the iron piece 3 has a certain shielding effect on the magnetic field generated by the magnet 2. When the magnetic field is close to the iron piece 3, the free electrons in the iron piece 3 will be affected by the external magnetic field and move, thereby generating a reverse magnetic field, which acts together with the external magnetic field to offset the external magnetic field, that is, reduce the strength of the magnetic field.

[0032] In the technical solution of the utility model, a magnet 2 is arranged on a mounting seat 1 far away from the circular blade 33, and an iron piece 4 is arranged on a cutter head 3 close to the circular blade 33, so that the magnetic attraction force generated by the magnet 2 on the circular blade 33 is reduced while realizing the magnetic attraction type disassembly and assembly of the cutter head 3, thereby preventing the circular blade 33 from being offset during rotation, reducing the load current, and improving the endurance performance of the shaver.

[0033] To improve the stability of the cutter head 3 after installation, please refer to Figure 4 In one embodiment of the utility model, there are multiple magnets 2, and they are distributed along the circumference of the mounting base 1. Since the iron piece 4 is installed corresponding to the magnet 2, the magnetic attraction force received by the cutter head 3 can be more uniform, thereby ensuring the stability of the cutter head 3 during shaving.

[0034] Further, in order to facilitate the circumferentially mounted magnets 2 to adsorb the iron piece 4, please refer to Figure 4 In one embodiment of the present invention, the iron piece 4 is in a circular ring shape, which further improves the stability of the cutter head 3 after installation.

[0035] To facilitate the installation of the ironwork 4, please refer to Figure 4 In one embodiment of the utility model, the iron piece 4 is provided with a plurality of first snap-in openings 41 , and the inner bracket 31 is provided with a plurality of first snap-in openings 311 , and each of the first snap-in openings 41 and each of the first snap-in openings 311 are snap-connected with each other.

[0036] As a preferred embodiment, four of the first bayonet 41 and four of the first buckle 311 are provided and are distributed along the circumferential direction to improve the stability of the iron piece 4 after installation.

[0037] To facilitate the connection of the inner bracket 31 and the outer bracket 32, please refer to Figure 4 In one embodiment of the utility model, the inner bracket 31 is provided with a plurality of second bayonet holes 312 , and the outer bracket 32 ​​is provided with a plurality of second buckles 321 , and each of the second bayonet holes 312 and each of the second buckles 321 are mutually engaged to fix the inner bracket 31 and the outer bracket 32 ​​together.

[0038] In order to enable the circular knife 33 to rotate in the mesh cover 34, please refer to Figure 4 In one embodiment of the present utility model, a rotating hole 313 is provided in the middle of the inner bracket 31 , and the rotating shaft 331 of the circular knife 33 is installed in the rotating hole 313 .

[0039] It should be understood that when installing the cutter head 3, the circular cutter 33 and the mesh cover 34 are first installed in the outer bracket 32, and fixed by the inner bracket 31, and then the iron piece 4 is clamped under the inner bracket 31 to form the entire cutter head 3. The magnet 2 is fixed in the mounting groove 11 of the mounting seat 1 to form the entire magnetic fixing structure 100.

[0040] The utility model also provides a shaver, which includes the magnetic attraction fixing structure of the shaver mentioned above, and of course also includes a driving part and a shell of the shaver.

[0041] 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.

[0042] 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.
