Problems solved by technology

[0006] In addition, the existing vacuum cleaners usually have sound-absorbing cotton on the side wall of the motor body, which will block the air from the motor body and affect the performance of the vacuum cleaner.
[0007] There are also vacuum cleaners on the market. A vibration isolation support is set between the motor body and the motor body casing to isolate the noise and vibration generated when the motor body is working. This requires at least four vibration isolation supports to be evenly arranged between the motor body and the motor casing The support, which will also block the air outlet of the motor body to a certain extent, thus affecting the performance of the vacuum cleaner

Embodiment 1

[0063] Please refer to figure 1 and figure 2 , figure 1 and figure 2 They are respectively the exploded schematic diagram and the assembled structure schematic diagram of the suspension noise reduction motor provided in this embodiment. The present invention provides a suspension type noise reduction motor, comprising a motor body 1 and a motor cover 2 at least partially containing the motor body 1, a sealing ring 6 is set on the air inlet 101 of the motor body, and the bottom of the motor body 1 is suspended, so that The main body of the motor 1 is "suspended" in the axial direction.

[0064] At least one elastic mechanism 4 is provided between the motor body 1 and the motor cover 2. The elastic mechanism 4 provides support or pulling force to the motor body 1 to offset the gravity of the motor body 1. The elastic mechanism 4 makes the motor body 1 "suspend" in the radial direction stand up.

[0065] In order to prevent the motor body 1 from colliding with the motor co...

Embodiment 2

[0075] Please refer to Figure 4 to Figure 6 , this embodiment discloses another implementation of the suspension noise reduction motor, the difference between this embodiment and Embodiment 1 is as follows:

[0076] The limit mechanism 5 is sleeved on the support frame 9, and the support frame 9 is fixed on the motor cover 2, and the support frame 9 can be fixed on the motor cover 2 by screwing. One end of the elastic mechanism 4 is fixed on the motor, and the other end is fixed on the support frame 9 through the support frame rubber 901. A limiting cavity 10 is formed between the support frame 9 and the motor cover 2, and the support frame is fixed to the motor cover by screws 902. superior. The limit mechanism includes a guide post 502, the head of the guide post 5021 is arranged in the limit cavity 10, the tail of the guide post is fixed on the motor, and the limit cavity 10 allows the head of the guide post 5021 to move up and down in the limit cavity 10 reciprocating m...

Abstract

A suspension noise-reduction motor comprises a motor body and a motor housing at least partially containing the motor body, an air inlet of the motor body is sleeved with a seal ring, at least one elastic mechanism is arranged between the motor body and the motor housing and provides supporting force or tension force for the motor body to offset gravity of the motor body, each elastic mechanism is arranged on a limiting mechanism in a sleeving mode, and the limiting mechanisms have the function of limiting the motor body in the deformation direction of the elastic mechanisms. Due to the elastic mechanisms and the limiting mechanisms, the motor body can only move within a certain range, and the elastic mechanisms and the limiting mechanisms have the limiting effect on the motor body to play roles in shock absorption and noise reduction; as few components are arranged around the motor, an air outlet of the motor body will not be blocked, and performance of a dust collector is guaranteed.

Description

technical field [0001] The invention relates to a suspension type noise-reducing motor, which is used in a vacuum cleaner and belongs to the technical field of vacuum cleaner equipment. Background technique [0002] Vacuum cleaners on the market, including upright vacuum cleaners, canister vacuum cleaners, hand-held vacuum cleaners, barrel vacuum cleaners, stick vacuum cleaners, backpack vacuum cleaners, carpet cleaners, bed vacuum cleaners, etc., will generate a lot of noise when users are using them , generally about 80 decibels, the noise of the vacuum cleaner is easy to upset, and it will affect the comfort of the user during use. [0003] At present, most vacuum cleaners are sound-proofed by installing a double-motor cover sound insulation structure of the motor inner cover and the motor outer cover outside the motor, and filling the air duct between the inner and outer cover of the motor to reduce noise energy, so as to achieve better reduction. noise effect. However...
