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 efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: a motor housing for multi-directional buffering and efficient heat dissipation of small household appliances, including a base 1, a housing 2 is fixedly installed at the upper end of the base 1, a vibration damping damper 3 is fixedly installed at the outer end of the housing 2, and a cooling chamber 4 is fixedly installed at the inner side of the vibration damping damper 3 and at the outer end of the housing 2. The cooling chambers 4 are equidistantly distributed at the outer end of the housing 2, and a through port 5 is fixedly arranged at the front end of the housing 2.

By installing the buffer arc plate 6, the outside of the motor can be supported. When the motor vibrates during operation, the damping liquid inside the vibration damping damper 3 is squeezed by the connecting block 7, thereby reducing vibration and greatly improving the shock absorption and noise reduction capabilities of the device.

[0023] Furthermore, a protection block 9 is fixedly installed at the outer end of the connecting block 7, a rubber block 10 is fixedly installed at the inner end of the housing 2, the shortest distance between the rubber block 10 and the protection block 9 is the same as the shortest distance between the connecting block 7 and the flow cavity 8, and a heat-conducting coating 11 is fixedly arranged at the outer end of the buffer arc plate 6. A circulation water pump 12 is fixedly installed inside the housing 2 below the buffer arc plate 6. By making the shortest distance between the rubber block 10 and the protection block 9 the same as the shortest distance between the connecting block 7 and the flow cavity 8, damage to the flow cavity 8 caused by excessive force on the connecting block 7 is avoided, and the service life of the device is greatly improved.

[0024] Furthermore, the connecting block 7 is of a hollow structure. A support seat 13 is fixedly installed inside the connecting block 7. A positioning rod 14 is fixedly installed at the inner end of the support seat 13. A return spring 15 is fixedly installed at the outer end of the positioning rod 14. A fixing block 16 is fixedly installed at the outer end of the buffer arc plate 6. The fixing block 16 is fixedly connected to the support seat 13 through the return spring 15. By installing the return spring 15, the fixing block 16 can apply a force to the support seat 13 to complete the outward movement of the connecting block 7. When the vibration reduction work is completed, the return spring 15 can automatically reset. By installing the positioning rod 14, it can prevent the return spring 15 from being overly distorted due to excessive force and resulting in the situation of being unable to reset, greatly improving the practicality of the device.

[0025] Furthermore, a slider 17 is fixedly installed at the outer end of the fixing block 16. A chute 18 is fixedly arranged at the inner end of the connecting block 7. The chute 18 is adapted to the slider 17. A buffer worm 19 is fixedly installed inside the housing 2 on the left side of the buffer arc plate 6. The inner end of the buffer worm 19 is meshed with a buffer worm gear 20. By making the chute 18 adapted to the slider 17, it is convenient for the fixing block 16 to move smoothly inside the connecting block 7. The transmission end of the motor passes through the inner end of the buffer worm gear 20 and extends to the outside of the through port 5. By making the inner end of the buffer worm 19 meshed with the buffer worm gear 20, the stability of the device is greatly improved.

[0026] Furthermore, a cooling pipe 21 is fixedly communicated with the outer end of the circulating water pump 12. A flow dividing valve 22 is fixedly installed at the outer end of the cooling pipe 21. The cooling pipe 21 extends into the cooling chamber 4. By installing the circulating water pump 12, it is convenient for the device to cool down. And the cooling pipe 21 extends into the cooling chamber 4. A heat conducting coating 11 is arranged at the outer end of the buffer arc plate 6, greatly improving the heat dissipation effect of the device.

[0027] Working principle: First, the driving end of the motor passes through the inner end of the buffer worm gear 20 and extends to the outside of the through port 5. By engaging the inner end of the buffer worm 19 with the buffer worm gear 20, the stability of the device is greatly improved. Then, the buffer arc plate 6 can support the outside of the motor. When the motor vibrates during operation, the damping liquid inside the shock absorber 3 is squeezed by the connecting block 7, thereby reducing vibration and greatly improving the shock absorption and noise reduction capabilities of the device. The shortest distance between the rubber block 10 and the protection block 9 is the same as the shortest distance between the connecting block 7 and the circulation cavity 8, thus avoiding excessive force on the connecting block 7 and damaging the circulation cavity 8, and greatly improving the service life of the device. Then, the return spring 15 enables the fixed block 16 to apply force to the support seat 13 to complete the outward movement of the connecting block 7. When the shock absorption work is completed, the return spring 15 can automatically reset. The positioning rod 14 can prevent the return spring 15 from being overly distorted due to excessive force and unable to reset, greatly improving the practicality of the device. The sliding groove 18 is adapted to the slider 17, facilitating the smooth movement of the fixed block 16 inside the connecting block 7. Finally, the circulating water pump 12 facilitates the cooling work of the device, and the cooling pipe 21 extends into the cooling chamber 4. The outer end of the buffer arc plate 6 is provided with a heat-conducting coating 11, greatly improving the heat dissipation effect of the device.
