Description

Technical Field

[0001] This utility model relates to the field of beauty and hair care electrical appliances, and in particular to an electric hair clipper with vibration reduction and noise reduction functions. Background Technology

[0002] Electric hair clippers are a common hairdressing tool, one of the most frequently used tools by hairdressers. They generally consist of the clipper head and the clipper body. The clipper body is the main functional component, primarily including the motor, battery, PCB control board, spring washers, rubber pads, and other auxiliary parts. The motor drives the rotation of an eccentric shaft, which in turn drives the clipper head. In existing technology, the motor mechanism of these electric hair clippers is mainly located on the body, and the motor uses a common internal rotor motor. However, this common motor is directly fixed inside the body, and when running at high speed, it generates vibration and loud noise, which greatly affects the user experience.

[0003] However, it is necessary to develop a powerful motor to overcome the aforementioned shortcomings, which would not only solve the problem of insufficient force but also allow users to more intuitively observe the motor's operation, and provide a fixing method that reduces vibration and noise. Therefore, it is necessary to improve the motor mechanism of traditional electric clippers. Utility Model Content

[0004] The purpose of this invention is to provide an electric clipper with vibration reduction and noise reduction functions, which can achieve the effect of noise reduction and at the same time make it convenient for users to observe the operation of the motor.

[0005] To achieve the above objectives, a vibration-damping and noise-reducing electric hair clipper is provided, comprising a housing, a fixed plate fixedly connected inside the housing, an external rotor motor disposed at the lower end of the fixed plate, a screw disposed inside the fixed plate, a spring washer disposed on the surface of the screw, a rubber pad disposed at the upper end of the external rotor motor, an eccentric shaft disposed inside the housing, a movable blade holder disposed at the upper end of the eccentric shaft, a blade head body disposed at the upper end of the movable blade holder, and an on / off switch disposed on the surface of the housing.

[0006] According to the electric clipper with vibration reduction and noise reduction function, the spring washer is positioned on the surface of the screw, and the spring washer is sleeved on the surface of the screw. By sleeved on the surface of the screw, the device is better fixed.

[0007] According to the electric clipper with vibration reduction and noise reduction function, the rubber pad is positioned at the upper end of the outer rotor motor. The rubber pad is in contact with the upper end of the outer rotor motor. By the rubber pad being in contact with the upper end of the outer rotor motor, the device reduces the vibration and noise caused by collision.

[0008] According to the electric clipper with vibration reduction and noise reduction function, the screw is located inside the fixing plate, and the screw is connected to the internal thread of the fixing plate, thereby making the device more secure.

[0009] This utility model has the following beneficial effects:

[0010] 1. Compared with existing technologies, the external rotor motor is fixed to the main body by spring washers and rubber pads. Due to the elasticity of the spring washers and the softness of the rubber pads, the two are more effectively reduced to avoid collisions and vibrations and noise, thereby achieving the effect of noise reduction.

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0017] Reference Figure 1-2This utility model discloses an electric hair clipper with vibration reduction and noise reduction functions. It includes a housing 1, a fixing plate 2 fixedly connected inside the housing 1, an external rotor motor 3 located at the lower end of the fixing plate 2, and screws 4 located inside the fixing plate 2. The screws 4 are threadedly connected to the inside of the fixing plate 2, thus ensuring better fixation of the device. A spring washer 5 is provided on the surface of the screw 4, fitting snugly against the surface of the screw 4. This fit further secures the device. A rubber pad 6 is provided at the upper end of the external rotor motor 3. At the upper end of the rotor motor 3, the rubber pad 6 is attached to the upper end of the outer rotor motor 3. The attachment of the rubber pad 6 to the upper end of the outer rotor motor 3 reduces the vibration and noise caused by collision. An eccentric shaft 7 is provided inside the housing 1. A movable tool holder 8 is provided at the upper end of the eccentric shaft 7. A tool head body 9 is provided at the upper end of the movable tool holder 8. An on / off switch 10 is provided on the surface of the housing 1. One end of the motor shaft is fixed to the motor rotor, and the other end is fixed to the eccentric shaft 7.
