The specific embodiment
Below in conjunction with preferred embodiment and accompanying drawing thereof, technical solution of the present invention is done further nonrestrictive detailed description.
Referring to figs. 1 through Fig. 2, corresponding to the dust catcher of preferred embodiment of the present invention, it is mainly used in family and other Code in Hazardous Special Locations cleanings, the motor 12 that it comprises housing section 10 and is positioned at housing section 10.Air inlet 25 is set, and air outlet 24 is arranged on housing section 10 below motor 12.In addition, housing section 10 comprises lower cover 15 and the top cover 14 that is arranged on lower cover 15.
With further reference to Fig. 3 to Fig. 4, above-mentioned dust catcher also comprises air-out air channel 34, and it is arranged between the air inlet 25 and air outlet 24 of described dust catcher.At least one anechoic chamber that described air-out air channel 34 is provided with power house 11 and is connected with power house 11.Said 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 sizes are uneven, sound wave cancelled out each other weak because reflection angle is different.
There is the upset break-in in airflow direction in the airflow direction of power house 11 and described at least one anechoic chamber on three-dimensional space position.Particularly, above-mentioned at least one anechoic chamber comprises and is arranged on power house 11 sides other the first anechoic chamber 27 and the second anechoic chamber 28 above power house 11 and the first anechoic chamber 27.There is the upset break-in in airflow direction in the airflow direction of power house 11 and the first anechoic chamber 27, the second anechoic chamber 28 on three-dimensional space position, the angle of upset break-in is between the 90-180 degree, and be sudden change between power house 11, the first anechoic chamber 27 and the second 28 threes' of anechoic chamber area of section size, wherein abrupt-change cross section is long-pending is more than 3 times of air inlet 25 areas.Described air-out air channel 34 inwalls add and post quieter material 38.Air-out described above air channel also is 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 the first aperture wooden partition 1 is more than 2.5 times of air inlet 25 areas, and the aperture centre-to-centre spacing of the first aperture wooden partition 1 and aperture ratio are more than 1.75, so that noise is brought up to the high-frequency range that people's ear can not be listened valve.And air-out air channel 34 also is provided with the second orifice wooden partition 2 that is positioned at air outlet 24 places, and the aperture gross area of described second orifice wooden partition 2 is more than 3 times of air inlet 25 areas.The aperture gross area of above-mentioned second orifice wooden partition 2 is more than 3 times of air inlet 25 areas.
In addition, the between the walls of above-mentioned top cover 14 and the second anechoic chamber 28 forms a layer of air separate space 16, because air is different to spread speed and the refraction angle of sound from solid, so just makes sound wave cancel out each other, and energy is weak.
the air-out air channel of disclosed dust catcher, as arrow a, b, c, shown in d, (arrow a) enters from air inlet its air-flow, at first through power house make progress (arrow b), then roughly turn over to turn 90 degrees on the three dimensions space and enter the first anechoic chamber (arrow c), the 90-180 degree that overturns obliquely again enters the second anechoic chamber (arrow d) from airduct 19, simultaneously fraction air-flow (as shown in arrow e) upwards flows out from the first aperture wooden partition 1 of disturbing flow device and also enters the second anechoic chamber, make two gangs of air-flow d and e in the second anechoic chamber 28 mutually collide and noise reduction, last air-flow flows out from air outlet through the second orifice wooden partition.As seen, the air-out air channel takes full advantage of cavity space, compound multiple noise reduction measure, and the noise reduction frequency range is wide, and complete machine is super-silent, and the ear sense is good.
It is pointed out that above-mentioned preferred embodiment only is explanation technical conceive of the present invention and characteristics, its purpose is to allow person skilled in the art scholar can understand content of the present invention and implement according to this, can not limit protection scope of the present invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
