Description

Technical FieldThe present invention relates to the technical field of electric devices for beauty and hair care, and more particularly to an electric hair clipper having vibration and noise reduction function.Prior ArtAn electric hair clipper is a frequently used tool for hair clipping and hair care and is among the most frequently used tools of hairdressers. It generally consists of an electric hair clipper head and an electric hair clipper housing. The electric hair clipper housing is the central functional unit of the apparatus and mainly comprises a motor, a battery, a PCB control board, and other accessories such as a spring washer and a rubber pad. The motor drives the eccentric shaft, which in turn drives the cutting head in motion. In the existing art, the motor device of the above electric hair clipper is mainly mounted on the housing, which is a conventional internal rotor motor. Since this motor is directly fastened in the housing, vibrations and strong noises are produced at high rotational speeds, which considerably impairs the user's experience of use.However, it is necessary to develop a high-performance motor device in order to solve the above-mentioned shortcomings. This should not only solve the problem of insufficient performance, but also allow the user to observe the operation of the motor more directly and, moreover, reduce vibrations and noises by an improved attachment method. Therefore, an improvement in motor construction of conventional electric hair clippers is necessary.Content of the Present Utility ModelThe object of the present invention is to provide an electric hair clipper having vibration and noise reduction functions, which enables effective noise reduction while facilitating the user to observe the operation of the motor.To achieve the above object, there is provided an electric hair clipper having vibration and noise reduction function, comprising a housing, a fixing plate being fixedly connected inside the housing, an outer rotor motor being disposed at the lower end of the fixing plate, screws being disposed inside the fixing plate, a spring washer being disposed on the surface of each of the screws, a rubber pad being disposed on the upper end of the outer rotor motor, an eccentric shaft being disposed inside the housing, a movable blade support being disposed at the upper end of the eccentric shaft, a blade body being disposed at the upper end of the movable blade support, and a switching knob being disposed at the surface of the housing.In the electric hair clipper having vibration and noise reduction functions, the position of the spring washer is disposed on the surface of the screw, and the spring washer is fitted on the surface of the screw. By placing the spring washer on the surface of the screw, the device is better fixed.In the electric hair clipper having vibration and noise reduction functions, the position of the rubber pad is located at the upper end of the outer rotor motor and the rubber pad abuts the upper end of the outer rotor motor. By abutting the rubber pad on the upper end of the outer rotor motor, the apparatus can reduce vibrations and noises caused by collisions.In the electric hair clipper having vibration and noise reduction functions, the position of the screw is disposed inside the fixing plate and connected to the internal thread of the fixing plate, so that the apparatus can be fixed more firmly.The present invention has the following advantageous effects: 1. the external rotor motor is fixed to the main body by means of spring washers and rubber pad, as compared with the prior art. Due to the elastic properties of the spring washer and the softness of the rubber pad, collisions and vibrations and noises caused thereby between both components are reduced more effectively, so that a noise reduction is achieved.Summary of the FiguresThe present utility model is explained in more detail below with reference to the figures and exemplary embodiments. FIG. 1 is a front view of an electric hair clipper having vibration and noise reduction functions according to this utility model. FIG. 2 is a side view of an electric hair clipper having vibration and noise reduction functions according to this utility model.Reference Number:1. Housing; 2. fastening plate; 3. external rotor motor; 4. screw; 5. spring washer; 6. rubber pad; 7. eccentric shaft; 8. movable blade carrier; 9. blade body; 10. switch knob.DETAILED EMBODIMENTSIn this section, the concrete embodiments of the present invention will be described in detail. The preferred embodiments are illustrated in the accompanying figures. The figures serve to graphically supplement the text descriptions of the patent specification, so that each technical property and the entire technical concept of the utility model can be understood in an illustrative and pictorial manner. However, they should not be taken as limiting the scope of the utility model.Referring to FIGS. 1 and 2, the electric hair clipper having vibration and noise reduction functions according to an embodiment of the present invention includes a housing 1, a fixing plate 2 is fixedly connected inside the housing 1, an external rotor motor 3 is disposed at the lower end of the fixing plate 2, screws 4 screwed to the internal threads of the fixing plate 2 are disposed inside the fixing plate 2, so that the apparatus is more firmly fixed. Spring washer 5 is arranged on the surface of each of the screws 4, the position of the spring washer 5 is arranged on the surface of the screw 4 and the spring washer 5 is fitted on the surface of the screw 4. By placing the spring washer 5 on the surface of the screw 4, the device is better fixed. A rubber pad 6 is disposed on the upper end of the outer rotor motor 3, and the position of the rubber pad 6 is disposed at the upper end of the outer rotor motor 3 and the rubber pad 6 abuts the upper end of the outer rotor motor 3. By abutting the rubber pad 6 on the upper end of the outer rotor motor 3, the apparatus can reduce vibrations and noises caused by collisions. An eccentric shaft 7 is arranged inside the housing 1, a movable blade support 8 is arranged at the upper end of the eccentric shaft 7, a blade body 9 is arranged at the upper end of the movable blade support 8, and a switching knob 10 is arranged on the surface of the housing 1. On the surface of the housing 1 is a knob 10, one end of the motor shaft is connected to the motor rotor, the other end to the eccentric shaft 7, and when the motor is energized through the knob 10, the shaft rotates together with the motor rotor; the other end, the eccentric shaft 7, rotates and drives the movable blade support 8. The upper blade is mounted on the movable blade carrier 8 so that the movement of the movable blade carrier 8 actuates the upper blade.Operating principle: The external rotor motor 3 is fastened to the main housing by means of spring washers 5 and the rubber support 6. Due to the elasticity of the spring washer 5 and the soft characteristics of the rubber pad 6, vibrations and noises caused by collisions between both components are more effectively reduced, so that noise reduction is achieved. One end of the motor shaft is connected to the motor rotor, the other end to the eccentric shaft 7, and when the motor is energized through the switch knob 10, the shaft and the motor rotor rotate together, and the eccentric shaft 7 at the other end drives the movable blade support 8. The upper blade is mounted on the movable blade carrier 8. The movement of the movable blade carrier 8 thus causes the operation of the upper blade, which makes it easier for the user to observe the motor operation.Above, an embodiment of this utility model has been explained in detail with reference to the attached figures. However, the utility model is not limited to the above-mentioned embodiments. Within the skill of one of ordinary skill in the art, various changes may be made without departing from the spirit of this utility model.
