Abstract
The invention discloses a noise reduction structure of a motor of a vacuum cleaner, which comprises a motor inner cover and a motor outer cover surrounding the motor. The noise reduction structure is characterized in that the lateral wall of the motor inner cover is provided with at least one sound deadening chamber. Compared with the prior art, because the lateral wall of the motor inner cover is provided with at least one sound deadening chamber which plays a good role in sound insulation and noise elimination, the noise reduction effect of the noise reduction structure of the motor of the vacuum cleaner is greatly enhanced.
Description
Technical field
The present invention relates to a kind of noise reduction structure of motor of vacuum cleaner.
Background technology
Basic identical to the comparatively effective denoising structure of motor of dust collector at present; The bi-motor cover sound insulating structure that promptly utilizes the motor inner cover to add the motor outer cover produces the effect of sound insulation; And increase sound-absorbing material (like the noise reduction sponge) reduction noise energy in the air channel between the motor inside and outside cover, to reach better noise reduction.Yet in the existing this denoising structure; Owing to be the single wall thick structure with the most approaching motor inner cover of motor; Itself can't play further sound insulation or sound deadening, and reduction noise energy that can't be strong is so limited to the whole noise reduction of denoising structure greatly.
Summary of the invention
The present invention seeks to: provide a kind of noise reduction better noise reduction structure of motor of vacuum cleaner.
Technical scheme of the present invention is: a kind of noise reduction structure of motor of vacuum cleaner, comprise the motor inner cover and the motor outer cover that surround motor, and it is characterized in that the lateral wall of said motor inner cover is provided with at least one silencing cavity.
Silencing cavity described in the present invention can be closed cavity.
When the silencing cavity among the present invention was closed cavity, this silencing cavity can adopt conventional air supporting injection mold moulding to form.Certainly; Processing also of said silencing cavity can be adopted following mode: with said motor inner cover adopt two on motor inner cover inner casing and motor inner cover shell independently parts combine to process the said enclosed silencing cavity of formation after combining between said motor inner cover inner casing and the motor inner cover shell through ultrasonic bonding or other connected mode (for example glue coheres).
Silencing cavity described in the present invention can be an open cavity also, and further is provided with the inner cover quieter material in it.
The quieter material of inner cover described in the present invention is specially inner cover noise reduction sponge or inner cover noise reduction felt or expanded material.
Among the present invention; The same with prior art; Offer first air outlet that is communicated with motor on the said motor inner cover, and offer second air outlet on the motor outer cover, said first air outlet is connected with second air outlet through the air channel that is formed between the inside and outside cover of motor.
And further be provided with outer cover noise reduction sponge in the said air channel.
And be filled with the air-out sponge in said second air outlet, and also be provided with air-out sea handkerchief in second air outlet outside.
On said motor outer cover inwall, further post the noise reduction felt relative among the present invention, keep n at regular intervals, n＞0 between the said noise reduction felt and first air outlet with first air outlet.The spacing size is decided according to actual conditions, can guarantee that the noise reduction felt can not stop up first air outlet and get final product.
Further be provided with motor noise reduction sponge between motor described in the present invention and the motor inner cover.
If the silencing cavity open cavity among the present invention, it directly can adopt conventional injection molding on the motor inner cover, to form so.
Advantage of the present invention is:
1. this noise reduction structure of motor of vacuum cleaner of the present invention; Compare prior art; Owing on the lateral wall of motor inner cover, set up at least one silencing cavity, this silencing cavity has played good sound insulation and sound deadening, thereby has strengthened the noise reduction of noise reduction structure of motor of vacuum cleaner greatly.
2. this noise reduction structure of motor of vacuum cleaner of the present invention because it has also filled the inner cover quieter material in silencing cavity, can further be cut down noise energy, thereby obtain better noise reduction.
