Abstract
The utility model discloses a noise reduction structure for a motor of a dust collector. The noise reduction structure comprises an air inlet, a movable air guide wheel and a static air guide wheel, wherein the air inlet is positioned on a motor shell, and the movable air guide wheel and the static air guide wheel are arranged in the motor shell and sequentially arranged below the air inlet; the noise reduction structure is characterized in that a noise reduction hood made from noise-reduction materials is arranged between the periphery of the static air guide wheel and the inner wall of the motor shell. Compared with the prior art, the noise reduction structure has the advantages of simple structure, easiness for implementation, low cost and good noise reduction effect.
Description
Technical field
The utility model 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 utility model purpose is: provide a kind of cost the low and noise reduction structure of motor of vacuum cleaner of excellent noise reduction effect.
The technical solution of the utility model 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 utility model, 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 utility model 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 utility model in the form of a ring.
Preferably, quieter material described in the utility model is the noise reduction sponge.
The utility model operation principle 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 utility model 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.
The utility model has the advantages that:
The utility model 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 utility model is further described:
Fig. 1 is a half sectional view of the present utility model;
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.
The utility model operation principle 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 utility model 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 utility model 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 utility model and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the spiritual essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
