Detailed description of the invention
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is further non-limitingly described in detail.
Referring to figs. 1 through Fig. 2, corresponding to the dust catcher of present pre-ferred embodiments, it is mainly used in family and other Code in Hazardous Special Locations cleanings, it motor 12 comprising housing section 10 and be positioned at housing section 10.Air inlet 25 is set in the below of motor 12, and air outlet 24 is arranged in housing section 10.In addition, housing section 10 comprises lower cover 15 and the top cover 14 be arranged on lower cover 15.
With further reference to Fig. 3 to Fig. 4, above-mentioned dust catcher also comprises exhaust air flue 34, and it is arranged between the air inlet 25 of described dust catcher and air outlet 24.At least one anechoic chamber that described exhaust air flue 34 is provided with power house 11 and is connected with power house 11.Above-mentioned motor 12 is arranged in power house 11, and its upper/lower terminal is equipped with cushion blocking 17, and the perisporium of motor 11 arranges ripple 18, and described ripple 18 size is uneven, makes sound wave cancel out each other weak because reflection angle is different.
Airflow direction in the airflow direction of power house 11 and at least one anechoic chamber described exists and overturns break-in on three-dimensional space position.Particularly, at least one anechoic chamber above-mentioned comprises and is arranged on the first other anechoic chamber 27 of power house 11 side and the second anechoic chamber 28 above power house 11 and the first anechoic chamber 27.Airflow direction in the airflow direction of power house 11 and the first anechoic chamber 28 of anechoic chamber 27, second exists and overturns break-in on three-dimensional space position, the angle of upset break-in is between 90-180 degree, and be sudden change between the area of section size of power house 11, first anechoic chamber 27 and the second anechoic chamber 28 three, wherein abrupt-change cross section amasss more than 3 times into air inlet 25 area.Described exhaust air flue 34 inwall adds and posts quieter material 38.Exhaust air flue described above is also provided with the disturbing flow device between the first anechoic chamber 27 and the second anechoic chamber 28, this disturbing flow device comprises the first aperture wooden partition 1, air-flow d in the air-flow e of this first aperture wooden partition 1 and the second anechoic chamber 28 collides with each other, and is convenient to like this reduce noise.In addition, the aperture gross area of described first aperture wooden partition 1 is more than 2.5 times of air inlet 25 area, and the small hole center of the first aperture wooden partition 1 distance and aperture are than more than 1.75, bring up to make noise the high-frequency range that people's ear can not listen valve.And exhaust air flue 34 is also provided with the second orifice wooden partition 2 being positioned at air outlet 24 place, the aperture gross area of described second orifice wooden partition 2 is more than 3 times of air inlet 25 area.The aperture gross area of above-mentioned second orifice wooden partition 2 is more than 3 times of air inlet 25 area.
In addition, the one deck of formation between the walls Air spacing pocket 16 of above-mentioned top cover 14 and the second anechoic chamber 28, because air is different with refraction angle to the spread speed of sound from solid, so just sound wave is cancelled out each other, energy is weak.
The exhaust air flue of disclosed dust catcher, as arrow a, b, c, shown in d, (arrow a) enters from air inlet its air-flow, first through power house upwards (arrow b), then roughly spatially turn over to turn 90 degrees at three dimensions and enter the first anechoic chamber (arrow c), overturn 90-180 degree more obliquely and enter the second anechoic chamber (arrow d) from airduct 19, fraction air-flow (as arrowe) upwards flows out from the first aperture wooden partition 1 of disturbing flow device and also enters the second anechoic chamber simultaneously, two gangs of air-flow d and e in the second anechoic chamber 28 are collided and noise reduction mutually, last air-flow flows out from air outlet through second orifice wooden partition.Visible, exhaust air flue takes full advantage of cavity space, the multiple noise reduction measure of compound, and noise reduction frequency range is wide, and complete machine is super-silent, and ear sense is good.
It is pointed out that above-mentioned preferred embodiment is only and technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
