Description
Technical field
the present invention relates to a kind of mute dust collector, particularly a kind of have a dust catcher that regular distribution has the silencing apparatus of micropore.
Background technology
dust catcher be a kind of by suction from floor or carpet get on except the electrical equipment of the dirts such as dust.In dust catcher, the air that contains dirt, through the inside of dust catcher, is then discharged dust catcher through air outlet.But, because being sucked rapidly dust catcher, air produces air-flow rapidly, the parts of air-flow and dust catcher inside clash into strongly rapidly, thereby when air is inner through dust catcher, produce very large noise, and this noise like is generally high-frequency noise, high-frequency noise makes user feel endurable, endangers people's health, and can shorten the service life of dust catcher.
for addressing the above problem, in prior art, with sponge-rubber pad, overlay on motor or blower fan surrounding, it is actual is a kind of impedance type noise reduction, just air-flow is stopped in certain space, air-flow can not promptly be dispersed elimination, air-flow is failed separated and is discharged into smoothly dust catcher outside, the noise that high velocity air produces is still present in a certain space in machine, can not effectively play noise reduction at all, but also can make machine itself increase extra unfavorable factor, as cause the motor temperature of machine to increase, the flow of body itself and efficiency reduce greatly etc.
Summary of the invention
for the problems referred to above, the object of this invention is to provide a kind of mute dust collector, the dissipation of heat that its noise is low, little to harm, efficiency is high, motor produces is fast.
for solving the problems of the technologies described above, the technical solution used in the present invention is:
a kind of mute dust collector, the shell that comprises hollow, blower fan is in the enclosure set, be opened in the air outlet on shell and be formed at described blower fan and described air outlet between air-out passage, in described air-out passage, be provided with a silencing means, described silencing means comprises the first dividing plate and the second partition arranging around described blower fan, described the first dividing plate is between blower fan and second partition, between described the first dividing plate and blower fan, form a vortex cavity, between described the first dividing plate and second partition, form a cushion chamber, on described the first dividing plate, offer one and by vortex cavity, be circulated to the opening of cushion chamber for air-flow, on described second partition, offer a plurality of micropores, air-flow in the air-out passage vortex cavity of flowing through successively, opening, cushion chamber, micropore.
preferably, described second partition comprise the body parallel with the first dividing plate and be fixedly connected on described body and the first dividing plate between connecting portion, on described body, offer a plurality of micropores of regular distribution.
more preferably, this dust catcher also comprise be opened in described side wall of outer shell bottom an air inlet, be arranged on the dust cover in described shell, the axial line of described air inlet is vertical with the axial line of dust cover.
further, the axial line of the body of described dust cover, blower fan, the first dividing plate and second partition parallels.
preferably, the top of described blower fan and below are respectively arranged with sealing gasket and lower seal plate, and described the first dividing plate is fixedly connected between described upper sealing gasket and lower seal plate.
more preferably, the body of described the first dividing plate, second partition is the cylindric of hollow.
preferably, the axial line of described opening and the axial line of micropore parallel.
preferably, described opening is opened in the centre position of the first dividing plate short transverse.
preferably, described air outlet is a plurality of and is opened in the top of side wall of outer shell.
operation principle of the present invention is as follows: dust-contained airflow is entered by air inlet, after filtering, dust cover forms clean gas flow, by blower fan running, drive and enter vortex cavity, air herein forms high velocity air owing to being subject to the stirring of blower fan and the pull of vacuum effect after motor running, high velocity air circular buffering in the first dividing plate vortex cavity of circulation silencing apparatus is discharged, consume the energy that part high velocity air and interior wall friction form high frequency noise, air-flow enters cushion chamber by the first dividing plate opening part again, air-flow continues circulation in second partition cushion chamber, the principle of disperseing according to flow in hydrodynamics, simultaneously air-flow is respectively by the micropore dispersion of a plurality of regular shapes, further consume the energy that forms high frequency noise, finally by air outlet, discharged.
the present invention adopts above structure, and tool has the following advantages: high velocity air first cushions in the first dividing plate, then by the micropore of regular shape in second partition cushion chamber, the audio frequency of high velocity air is dispersed, reduces noise; Compared with prior art, the noise abatement of not only can thoroughly eliminating the noise, the amount of heat of also having avoided motor running to produce simultaneously can not comparatively fast be discharged the problem of air outlet, prevents the reduction of the flow of dust catcher own and efficiency.
