Description

Technical Field

[0001] The utility model belongs to the technical field of hair trimming, in particular to an electric hair trimmer. Background Art

[0002] The close contact between the fixed blade 3 and the movable blade 1 of the hair trimmer is the key to ensure hair cutting. If the pressure is too small, hair cutting cannot be achieved and the noise is loud. If the pressure is too high, the discharge amount will increase. The existing technologies on the market are all achieved by springs 2 (such as Figure 1 As shown), however, the force error of spring 2 is large and difficult to control, and the elastic force of the spring will gradually weaken over time, resulting in subsequent inability to shear hair. Utility Model Content

[0003] The technical problem to be solved by the utility model is how to enable the moving knife to obtain a more stable pressure.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] An electric hair trimmer comprises a fixed blade part, a movable blade part, a movable blade driving mechanism, a shell and a power supply. The fixed blade part is provided with one or more magnetic suction parts for making the movable blade and the fixed blade in close contact.

[0006] When the magnetic attraction component is arranged between the movable knife part and the fixed knife part, a recessed portion for installing the magnetic attraction component is provided on the inner wall of the fixed knife part, and the fixed knife part magnetically matched with the magnetic attraction component is made of a material that can be attracted by a magnet, so that the movable knife and the fixed knife end can fit tightly after the magnetic attraction component is installed.

[0007] Preferably, the magnetic attraction member is a magnet.

[0008] Preferably, a mounting groove is provided on the fixed knife assembly where the magnetic attraction member is mounted, and the magnetic attraction member is fixedly mounted in the mounting groove.

[0009] Preferably, the magnetic attraction member is in the shape of an elongated strip.

[0010] The beneficial effect of the utility model is that the utility model replaces the traditional spring with a magnetic suction part, and the stable magnetic suction force ensures that the movable knife assembly can be in better and closer contact with the fixed knife, so that the sharpness and noise of hair cutting are improved. The present invention preferably adopts the method of setting a magnetic component between the fixed knife assembly and the movable knife assembly, and fixing the magnetic suction part on one side of the fixed knife, which has the advantage of ensuring stable suction force without affecting the product appearance, and improving the product experience.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figure 2 and Figure 3 , the figure shows an electric hair trimmer, which is actually a hair clipper, including a fixed blade 3 part, a movable blade 1 part, a movable blade driving mechanism 6, a housing 4, a switch 7 and a power supply 8. These mechanisms are conventional technologies on the market and will not be elaborated in detail here. It is worth noting that in this embodiment, a magnetic attraction part 5 is provided between the movable blade 1 part and the fixed blade 3 part to enable the movable blade 1 and the fixed blade 3 to be in close contact. The magnetic attraction part 5 is a magnet. The magnetic part can be one or more pieces. This embodiment adopts one piece and is designed as a long strip structure. After the magnet is installed in the fixed blade assembly, the magnet does not contact the surface of the movable blade assembly, thereby ensuring that the movable blade assembly can run smoothly. In this embodiment, a recessed part for installing the magnetic attraction part 5 is provided on the inner wall of the fixed blade 3 part. The fixed blade 3 part that is magnetically matched with the magnetic attraction part 5 is made of a material that can be attracted by a magnet, so that the movable blade 1 and the fixed blade 3 end can fit closely after the magnetic attraction part 5 is installed.

[0019] A mounting groove is provided on the fixed knife 3 component where the magnetic suction member 5 is mounted, and the magnetic suction member 5 is fixedly mounted in the mounting groove. The connection can be made by tight fitting, bonding, etc. The present invention uses a strong magnet to adsorb the movable knife 1 component, ensuring that the movable knife 1 component always maintains the same suction force when moving to different positions at high speed.
