Example Embodiment

[0017] The solution is described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018] See Figure 1-3 , The present invention provides a technical solution: a motor with noise reduction and vibration reduction functions, comprising a rotor core 13, a shock absorber 14 and a noise reduction box 20, the upper and lower ends of the rotor core 13 are movably connected with The stator winding 4, the upper end of the stator winding 4 is fixedly connected with a stator core 6, the middle of the stator core 6 is provided with a shaft 1, and the upper end of the stator core 6 is fixedly connected with a soundproof housing 5. The right end of the rotor core 13 is fixedly connected to the rotor winding 12, the right side of the rotor winding 12 is provided with a bearing 11, and the bearing 11 is movably connected with the shaft 1, and the inner part of the shock absorber 14 is movably connected with The piston rod 17 has a balance hole 21 through the right end of the noise reduction box 20.

[0019] Further, a slip ring 10 is provided on the right side of the bearing 11, and the slip ring 10 is movably connected to the shaft 1, and the slip ring 10 changes the commutation of output and input current.

[0020] Further, a brush 8 is fixedly connected to the upper end of the slip ring 10, a brush cover 7 is fixedly connected to the upper end of the brush 8, and an end cover 9 is fixedly connected to the right end of the brush cover 7 through the electric The brush cover 7 protects the brush for 8 periods.

[0021] Further, a fan cover 3 is provided on the left side of the soundproof housing 5, a fan 2 is provided on the right side of the fan cover 3, and the fan 2 is movably connected to the shaft 1, and the fan 2 in the device The heat is dissipated to ensure that the device works for a long time.

[0022] Further, the middle of the front end of the piston rod 17 is movably connected with a second piston valve 18, the lower side of the second piston valve 18 is provided with a main piston valve 19, and the outer wall of the piston rod 17 is respectively provided with a support spring 16 And the limit spring 15, through the support spring 16 and the limit spring 15 to dampen the device, prevent severe shaking and damage the parts.

[0023] Further, a sound-absorbing sponge 22 is fixedly connected to the inside of the noise reduction box 20, and the sound-absorbing sponge 22 absorbs noise generated in the device to reduce noise.

[0024] Working principle: This kind of motor with noise reduction and shock absorption function, firstly, connect the power supply, and drive the rotor winding 12 to rotate through the rotation of the rotor core 13 and then drive the device to rotate. The fan 2 radiates the heat in the device and passes The fan cover 3 protects the fan 2 to ensure that the device can run for a long time. Secondly, the support spring 16, the limit spring 15 and the piston rod 17 in the shock absorber 14 disperse the pressure generated during the operation of the motor to ensure that the device does not It will shake violently to protect the parts from loosening. A soundproof housing 5 is installed outside the motor, and the noise is absorbed by the sound-absorbing sponge 22 in the noise reduction box 20, which can reduce the noise and make the user comfortable to use. Finally, in use After that, turn off the power.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible for those skilled in the art to modify the technical solutions described in the foregoing embodiments, or make equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
