Description
Technical field
the present invention relates to a kind of mute dust collector, particularly a kind of have the dust catcher that regular distribution has the silencing apparatus of micropore.
Background technology
dust catcher is a kind of by aspirating to get on except the electrical equipment of the dirts such as dust from floor or carpet.In dust catcher, the air containing dirt, through the inside of dust catcher, then discharges dust catcher through air outlet.But, air-flow is rapidly produced because air is sucked rapidly dust catcher, the parts of air-flow and dust catcher inside clash into strongly rapidly, thus when dust catcher is inner, produce very large noise at air, and this noise like is generally high-frequency noise, high-frequency noise makes user feel to be difficult to stand, the health of harm people, and can shorten the service life of dust catcher.
for solving the problem, motor or blower fan surrounding is overlayed on sponge-rubber pad in prior art, it is actual is a kind of impedance type noise reduction, namely just air-flow is stopped in certain space, air-flow can not promptly be eliminated by dispersion, air-flow is failed separated and is discharged into dust catcher outside smoothly, the noise that high velocity air produces still is present in a certain space in machine, effectively can not play noise reduction at all, but also machine itself can be made to increase extra unfavorable factor, as caused, the motor temperature of machine increases, the flow of body itself and efficiency reduce greatly.
Summary of the invention
for the problems referred to above, the object of this invention is to provide a kind of mute dust collector, its noise be low, little to harm, efficiency is high, motor produce heat distribute soon.
for solving the problems of the technologies described above, the technical solution used in the present invention is:
a kind of mute dust collector, comprise the shell of hollow, blower fan is in the enclosure set, the air-out passage being opened in the air outlet on shell and being formed between described blower fan and described air outlet, a silencing means is provided with in described air-out passage, described silencing means comprises the first dividing plate and second partition that arrange around described blower fan, described first dividing plate is between blower fan and second partition, a vortex cavity is formed between described first dividing plate and blower fan, a cushion chamber is formed between described first dividing plate and second partition, described first dividing plate offering one supplies air-flow to be circulated to the opening of cushion chamber by vortex cavity, described second partition offers multiple micropore, air-flow in air-out passage flows through vortex cavity successively, opening, cushion chamber, micropore.
preferably, the connecting portion that described second partition comprises the body parallel with the first dividing plate and is fixedly connected between described body and the first dividing plate, described body offers multiple micropores of regular distribution.
more preferably, this dust catcher also comprises the air inlet being opened in described side wall of outer shell bottom, the dust cover be arranged in described shell, and 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 first dividing plate is fixedly connected between described upper sealing gasket and lower seal plate.
more preferably, the body of described first dividing plate, second partition is the cylindrical shape of hollow.
preferably, the axial line of described opening parallels with the axial line of micropore.
preferably, described opening is opened in the centre position in the first divider height direction.
preferably, described air outlet is multiple 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, clean gas flow is formed after dust cover filters, vortex cavity is entered by blower fan running drive, air herein forms high velocity air owing to being subject to the pull of vacuum effect after the stirring of blower fan and motor running, high velocity air is discharged in the first dividing plate vortex cavity Inner eycle buffering of circulation silencing apparatus, consume the energy that part high velocity air and interior wall friction form high frequency noise, air-flow enters cushion chamber by the first bulkhead apertures again, air-flow continues circulation in second partition cushion chamber, according to the principle of flow dispersion in hydrodynamics, air-flow is respectively by the micropore dispersion of multiple regular shape simultaneously, the further energy consuming formation high frequency noise, finally discharged by air outlet.
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 by dispersed for the audio frequency of high velocity air, reduces noise; Compared with prior art, noise abatement of not only can thoroughly eliminating the noise, the amount of heat that simultaneously it also avoid motor running generation comparatively fast can not discharge the problem of air outlet, prevents the reduction of the flow of dust catcher own and efficiency.
