Problems solved by technology

[0003] 1. Work hard on the motor itself to obtain low noise output by reducing power consumption while ensuring its working efficiency. However, the cost of this approach is high, and the actual noise reduction effect is not ideal;
[0004] 2. Improve the air guide channel inside the motor shell, such as improving the shape of the dynamic and static wind guide wheels, or reducing noise by adding structures such as anechoic chambers and air guide pipes. The disadvantage is that the structural design of the motor shell is complicated. The difficulty of model manufacturing increases and the cost increases;
[0005]3. Since the low-frequency noise of the vacuum cleaner mainly comes from the vibration of the motor, in order to reduce the vibration of the motor, the industry fixes the motor by fixing the motor sealing ring and the motor press seat front and back into the motor cover, but the existing motor and motor cover are mostly rigidly connected, the noise reduction effect is still limited, and resonance may also occur, making it impossible to achieve low noise of the motor

Abstract

The present invention discloses a motor denoising structure applied to vacuum cleaners, with a spring device 4 disposed between a motor support 3 and a motor cover 2 to support the motor support 3; in the present invention the motor cover 2 supports the motor support 3 through the spring device 4, such a flexible connection reducing noise while reducing vibration.

Description

technical field [0001] The invention relates to a motor noise reduction structure applied to a vacuum cleaner. Background technique [0002] As the motor power of the vacuum cleaner gradually increases, the noise of the vacuum cleaner also increases. In the prior art, in order to solve the noise problem of the vacuum cleaner motor, various manufacturers usually adopt the following methods: [0003] 1. Work hard on the motor itself to obtain low noise output by reducing power consumption while ensuring its working efficiency. However, the cost of this approach is high, and the actual noise reduction effect is not ideal; [0004] 2. Improve the air guide channel inside the motor shell, such as improving the shape of the dynamic and static wind guide wheels, or reducing noise by adding structures such as anechoic chambers and air guide pipes. The disadvantage is that the structural design of the motor shell is complicated. The difficulty of model manufacturing increases and th...
