Description

Hair trimmer, main machine of hair trimmer and assembling method of main machine

Technical Field

The present invention relates to the field of manual cutting tools, and more particularly to a hair trimmer, a main body of the hair trimmer, and an assembling method thereof.

Background

Shavers, hair clippers and the like are common hair trimmers in life. The hair trimmer drives the cutter head to work through the motor to remove the hair.

A typical hair trimmer includes a housing, a cutter head, and a power supply and power assembly enclosed by the housing, the power supply and power assembly being disposed directly within the housing so that the power supply and power assembly is isolated from the environment only by the housing. The power assembly obtains electric energy from the power supply, and after the electric energy is converted into kinetic energy, the power assembly drives the outer head outside the shell to work, and the power assembly can vibrate when generating the kinetic energy to drive the whole hair trimmer to vibrate. Since the power assembly is spaced from the outside only by the housing, the vibration generated by the power assembly is directly transmitted to the user's hand through the housing. When a user holds the shell of the hair trimmer, the user can feel the vibration transmitted by the power assembly through the shell directly, the vibration sense is strong, and the user can be uncomfortable.

The environment of use of hair trimmers is often accompanied by water, hair-use detergents, conditioners and other fluids. If the shaver contacts shaving water during use, the shaver contacts depilating water, the hair pusher contacts shampoo and the like, various fluids may flow into the interior of the housing through gaps in the housing, gaps between the cutter head and the housing due to installation, and the like, and contact the power source and the power assembly. Fluid contact with the power supply has the potential to cause leakage, and fluid contact with the power assembly has the potential to damage the power assembly. Merely encasing the power supply and power assembly with a separate housing does not isolate the flow of fluid into the interior of the housing, resulting in a short life of the hair trimmer.

Furthermore, different brands of hair trimmers have their own unique or novel design requirements, but the internal power supply and power components are not subject to much design variation due to the maturity and stability of the technology. Therefore, the housing of the hair trimmer is changed more, but the internal design is often changed less, the housing is adjusted according to the requirement of the appearance design, and the internal power supply and the power assembly are required to be installed in a matching mode. The stable installation of internal power source and power component need utilize multiple tiny structures such as screens structure, fixed knot to construct, if the shell uses plastic material, the realization degree of difficulty angle of these tiny structures. However, the housing made of plastic material is cheap and has insufficient design feeling and texture. If the shell is made of metal materials, the aesthetic feeling and the design feeling are strong, but the manufacturing difficulty for realizing a fine structure is large, so that the shell made of the metal materials is difficult to realize the stable installation of an internal power supply and a power assembly. And the power supply is directly wrapped by the shell made of metal materials, so that the hidden troubles of electric conduction and electric leakage exist.
