Abstract
The invention discloses a motor for a dust collector. The motor comprises an air inlet positioned on a motor housing, and a movable inducer, a stationary inducer and a motor body which are arranged in the motor housing and sequentially distributed below the air inlet. The motor is characterized in that: a silencing hood made from a silencing material is arranged between the periphery of the stationary inducer and the inner wall of the motor housing; and simultaneously, a silencing partition board made from the silencing material is arranged between the stationary inducer and the motor body. The motor for the dust collector has low cost and good noise reduction effects.
Description
Technical field
the present invention relates to a kind of motor of dust collector.
Background technology
In
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 through 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 through 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 motor of dust collector comprises the air inlet that is positioned on the motor housing, and is located at moving inducer, quiet inducer and the motor body 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 processing by quieter material between said quiet inducer periphery and the motor housing inwall, be provided with the sound gobo of processing by quieter material between quiet inducer and the motor body simultaneously.
are further, and sound gobo described in the present invention is clamped and fixed between quiet inducer and the motor body, have the hole that the rotating shaft of power supply machine body is stretched out on it.
are 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, said wind-guiding is provided with the silencer cover of being processed by quieter material in the gap.
are the same with routine techniques, and moving inducer is fixed in the rotating shaft of motor body described in the present invention; Said quiet inducer and motor housing inwall are fixed.
are preferred, and silencer cover described in the present invention in the form of a ring.
are preferred, and the quieter material of silencer cover described in the present invention and sound gobo is the noise reduction sponge.
operation principle of the present invention is following: after the motor of dust collector running; The passive inducer of outside air sucks in the air inlet; Along the impeller clearance of moving inducer to around discharge; Through the last impeller clearance that gets into quiet inducer, the wind-guiding gap between quiet inducer and the motor housing inwall; Through motor body, discharge to the motor housing rear portion at last subsequently.Owing to added silencer cover in the wind-guiding gap of the present invention between quiet inducer and motor housing inwall; Simultaneously between quiet inducer and motor body, be provided with sound gobo; These two noise reduction parts can greatly absorb and weaken the acoustic energy of the air-flow of flowing through, thereby effectively reduce motor noise more.
Advantage of the present invention is:
this motor of dust collector 1. provided by the invention, it compares prior art, and is simple in structure, easy to implement, and cost is low, and excellent noise reduction effect.
this motor of dust collector 2. provided by the invention; It is compared, and increase noise reduction parts weaken outside the air-flow acoustic energy of flowing through here in the simple wind-guiding gap between quiet inducer and motor housing inwall; Also take into account the noise reduction process of the air-flow between quiet inducer and the motor body of flowing through simultaneously, effectively raised noise reduction more.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
Fig. 1 is half sectional view of the present invention (white arrow is the air-flow trend among the figure);
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; 7, sound gobo.
Embodiment
embodiment: combine 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; Said motor housing 1 is provided with air inlet 2; Be fixed with moving inducer 3 in the rotating shaft of said motor body 6; Said moving inducer 3 is positioned at air inlet 2 belows, and through screw the quiet inducer 4 that is positioned at moving inducer 3 belows is arranged on motor housing 1 inwall.Grip the sound gobo of processing by quieter material 7 between said quiet inducer 4 and the motor body 6, have the hole that the rotating shaft of power supply machine body 6 is stretched out on this sound gobo 7.Said 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 processing by quieter material 5 in the said wind-guiding gap.Silencer cover described in the present embodiment 5 in the form of a ring, and the quieter material of said silencer cover 5 and sound gobo 7 is the noise reduction sponge.
operation principle of the present invention is following: after the motor of dust collector running; The passive inducer 3 of outside air sucks in the air inlet 2; Along the impeller clearance of moving inducer 3 to around discharge; Through the last impeller clearance that gets into quiet inducer 4, the wind-guiding gap between quiet inducer 4 and motor housing 1 inwall; Through motor body 6, discharge to motor housing 1 rear portion at last subsequently.Owing to added silencer cover 5 in the wind-guiding gap of the present invention between quiet inducer 4 and motor housing 1 inwall; Simultaneously between quiet inducer 4 and motor body 6, be provided with sound gobo 7; These two noise reduction parts can greatly absorb and weaken the acoustic energy of the air-flow of flowing through, thereby effectively reduce motor noise.
this motor of dust collector that present embodiment provides is compared prior art, and it is simple in structure, and is easy to implement, and cost is low, and excellent noise reduction effect.
This motor of dust collector that
present embodiment provides; It is compared, and increase noise reduction parts weaken outside the air-flow acoustic energy of flowing through here in the simple wind-guiding gap between quiet inducer 4 and motor housing 1 inwall; Also take into account the noise reduction process of the air-flow between quiet inducer 4 and the motor body 6 of flowing through simultaneously, effectively raised noise reduction more.
the foregoing description certainly only are 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 spirit 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.
