Description

Technical Field

[0001] This utility model relates to the field of electric clippers, and in particular to an electric clipper with a viewing window. Background Technology

[0002] Electric clippers are a common hairdressing tool, and one of the most frequently used tools by hairdressers. They generally consist of clipper heads and clipper bodies. The clipper body is the main functional component of the clipper, mainly including a motor, battery, PCB control board, and other accessories. The motor drives the rotation of the eccentric shaft, which in turn drives the clipper head.

[0003] In existing technologies, the motor mechanism of electric hair clippers is mainly located on the main body, and the motor is usually a common internal rotor motor. However, the lifespan of a common internal rotor motor is short, which makes electric hair clippers prone to failure, thus affecting their normal service life. In addition, the torque output of a common internal rotor motor is relatively small, which directly results in insufficient force when the electric hair clipper is working. When trimming thick and coarse hair, it often gets stuck and difficult to cut, failing to provide users with an efficient and smooth trimming experience. Therefore, there is a need for an electric hair clipper with a viewing window. Utility Model Content

[0004] The purpose of this invention is to provide an electric hair clipper with a viewing window. The motor rotor is located outside the stator. With the rotor on the outside, the moment of inertia is larger, and it can output greater torque at the same power. This avoids jamming and difficulty in cutting thick and coarse hair, improving the user experience. In addition, the greater output torque at the same power can better drive large loads. When driving the same load, the workload of the external rotor motor is relatively lower, and the wear inside the motor is also relatively smaller, thus extending the service life of the electric hair clipper.

[0005] To achieve the above objectives, an electric hair clipper with a viewing window is provided, comprising an electric hair clipper body, a transparent window fixedly connected to the electric hair clipper body, a motor stator fixedly connected to the inner surface of the electric hair clipper body, a motor rotor disposed on the motor stator, an output shaft fixedly connected to the motor rotor, an eccentric shaft fixedly connected to the output shaft, a movable blade holder fixedly connected to the eccentric shaft, and a blade head disposed on the movable blade holder.

[0006] According to the electric clipper with a viewing window, the main body of the electric clipper is respectively provided with a power indicator light cover and a power switch.

[0007] According to the electric clipper with a viewing window, the output shaft and the eccentric shaft are both located inside the electric clipper body.

[0008] The above-mentioned solution has the following beneficial effects:

[0009] By designing the motor rotor, stator, and output shaft, this solution places the motor rotor outside the stator. With the rotor external, its rotational inertia is greater, allowing it to output more torque at the same power. This prevents jamming and difficulty in cutting thicker, stiffer hair, improving the user experience. Furthermore, the greater torque at the same power allows for better driving of heavy loads. When driving the same load, the external rotor motor has a relatively lower workload, resulting in less internal wear and extending the lifespan of the electric hair clippers.

[0010] The transparent window allows for clear observation of the motor rotor's movement. By directly observing the rotor's motion, users can see its rotation trajectory, speed uniformity, and other characteristics. Any abnormalities can be detected promptly, thus increasing the overall practicality of the device.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0018] 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.

[0019] Reference Figure 1-3This utility model discloses an electric hair clipper device with a viewing window, comprising an electric hair clipper body 1, a transparent window 2 fixedly connected to the electric hair clipper body 1, a motor stator 4 fixedly connected to the inner surface of the electric hair clipper body 1, a motor rotor 3 mounted on the motor stator 4, an output shaft 5 fixedly connected to the motor rotor 3, an eccentric shaft 6 fixedly connected to the output shaft 5, a movable blade holder 7 fixedly connected to the eccentric shaft 6, and a blade head 8 mounted on the movable blade holder 7. The electric hair clipper body 1 is respectively provided with a power indicator light cover 9 and a power switch 10. The output shaft 5 and the eccentric shaft 6 are both located inside the electric hair clipper body 1. It should be noted that the motor rotor 3... The motor rotor 3 is electrically connected to the switch 10 via an external power supply. The operating principle of the motor rotor 3 is that coils are usually wound on the motor rotor 3. When current flows through the coils, these current-carrying conductors are subjected to Ampere force in the magnetic field generated by the motor stator 4. Due to the coil distribution on the motor rotor 3 and the characteristics of the magnetic field of the motor stator 4, these Ampere forces will form a torque that makes the motor rotor 3 rotate, thereby driving the motor rotor 3 to rotate. Furthermore, various patterns can be set on the motor rotor 3, and beautiful patterns can be seen whether it is running or stopped, which can effectively relieve the mental stress of the user during operation.

[0020] Working principle: The motor rotor 3, motor stator 4 and output shaft 5 form an external rotor motor. When the motor is started by the switch 10 on the electric clipper body 1, the motor rotor 3 and output shaft 5 can rotate together. The rotating output shaft 5 can drive the eccentric shaft 6 to rotate. At this time, the rotating eccentric shaft 6 can drive the movable blade holder 7 and the blade head 8 on the movable blade holder 7 to start operating. At this time, the electric clipper body 1 can be used normally. Through the transparent window 2 set on the electric clipper body 1, the movement of the motor rotor 3 can be clearly observed. By observing the movement of the motor rotor 3, it is possible to intuitively judge whether its operation is stable, allowing the user to detect any abnormalities of the motor rotor 3 in time.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
