Abstract
The invention discloses a de-noising structure of a dust collector motor. The structure comprises an air inlet positioned on a motor shell, and a dynamic wind guide wheel and a static wind guide wheel which are arranged in the motor shell and sequentially arranged below the air inlet. The structure is characterized in that: a silencing hood made of silencing material is arranged between the periphery of the static wind guide wheel and the inner wall of the motor shell. Compared with the prior art, the structure is simple and easy to implement, and has low cost and good de-noising effect.
Description
Technical field
The present invention relates to a kind of noise reduction structure of motor of vacuum cleaner.
Background technology
In the prior art in order to solve the noise problem of motor of dust collector, each producer usually summarize take following two kinds by way of, a kind of is to work hard from motor itself, obtain to export by when guaranteeing its operating efficiency, reducing power consumption than low noise, yet this by way of cost higher, and actual noise reduction is not satisfactory; Another kind of then be that air-guiding aisle to motor housing inside improves, for example improve the shape of dynamic and static inducer, perhaps cut down noise by setting up structures such as anechoic chamber, wind-guiding pipeline, its shortcoming is to cause the motor housing complex structural designs, the model manufacture difficulty increases, cost up.
Summary of the invention
The present invention seeks to: provide a kind of cost the low and noise reduction structure of motor of vacuum cleaner of excellent noise reduction effect.
Technical scheme of the present invention is: a kind of noise reduction structure of motor of vacuum cleaner comprises the air inlet that is positioned on the motor housing, and is located at moving inducer and the quiet inducer that also is arranged in the air inlet below in the motor housing successively; It is characterized in that being provided with the silencer cover of making by quieter material between described quiet inducer periphery and the motor housing inwall.
The same with routine techniques, motor body is installed in the motor housing described in the present invention, described moving inducer is fixed in the motor body rotating shaft, and quiet inducer is fixed on the motor body.
Further, quiet inducer described in the present invention peripheral with the motor housing inwall between be provided with the wind-guiding gap that communicates with moving inducer impeller clearance, described wind-guiding is provided with the silencer cover of being made by quieter material in the gap.
Preferably, silencer cover described in the present invention in the form of a ring.
Preferably, quieter material described in the present invention is the noise reduction sponge.
Operation principle of the present invention is as follows: after the motor of dust collector running, the passive inducer of outside air sucks in the air inlet, to discharging all around, discharge to the motor rear portion impeller clearance that enters quiet inducer by the wind-guiding gap between quiet inducer and the motor housing inwall at last along the impeller clearance of moving inducer.Owing to added silencer cover in the wind-guiding gap of the present invention between quiet inducer and motor housing inwall, can greatly absorb and weaken the acoustic energy of the air-flow of flowing through, thereby effectively reduce motor noise.
Advantage of the present invention is:
The present invention compared to existing technology, it is simple in structure, and is easy to implement, cost is low, and excellent noise reduction effect.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is a half sectional view of the present invention;
Fig. 2 is the A-A view of Fig. 1.
Wherein: 1, motor housing; 2, air inlet; 3, moving inducer; 4, quiet inducer; 5, silencer cover; 6, motor body.
The specific embodiment
Embodiment: in conjunction with Fig. 1, shown in Figure 2, this noise reduction structure of motor of vacuum cleaner that present embodiment provides, have motor housing 1 and the motor body 6 that is installed in the motor housing 1, described motor housing 1 is provided with air inlet 2, be fixed with moving inducer 3 in described motor body 6 rotating shafts, described moving inducer 3 is positioned at air inlet 2 belows, and is fixed with the quiet inducer 4 that is positioned at moving inducer 3 belows on the motor body 6.Described moving inducer 3 and quiet inducer 4 all are positioned at motor housing 1.Described quiet inducer 4 peripheral with motor housing 1 inwall between be provided with the wind-guiding gap that communicates with moving inducer 3 impeller clearances, be provided with the silencer cover of making by quieter material 5 in the described wind-guiding gap.In the present embodiment this silencer cover 5 in the form of a ring, and described quieter material is the noise reduction sponge.
Operation principle of the present invention is as follows: after the motor of dust collector running, the passive inducer 3 of outside air sucks in the air inlet 2, to discharging all around, discharge to the motor rear portion impeller clearance that enters quiet inducer 4 by the wind-guiding gap between quiet inducer 4 and motor housing 1 inwall at last along the impeller clearance of moving inducer 3.Owing to added silencer cover 5 in the wind-guiding gap of the present invention between quiet inducer 4 and motor housing 1 inwall, can greatly absorb and weaken the acoustic energy of the air-flow of flowing through, thereby effectively reduce motor noise.
The present invention compared to existing technology, it is simple in structure, and is easy to implement, cost is low, and excellent noise reduction effect.
Certainly the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.The all spiritual essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
