Description
Technical field
The present invention relates to the technical field of dust catcher, a kind of specifically mute ducting system of dust catcher.
Background technology
Dust catcher is as common electric appliance, since motor is typically all to be directly installed in main body, without remaining sealing
Sound arrester causes dust catcher at present on the market that can generate very big noise in use, makes one to upset, seriously
Influence user experience.Most of dust catchers be all by installing the sound insulating structures such as inner motor cover and outer cover outside motor come sound insulation,
But the noise reduction of this dust catcher is general, hard due to motor and motor cover contacts, and when use still sends out loud noise, because
This motor typically directly uses sponge to carry out noise reduction as sound-absorbing material, and still, when wind is by air duct, generated noise is also
One big puzzlement.

After more than structure, the mute ducting system of a kind of dust catcher of the invention has following excellent compared with prior art
Point：
1st, sound-absorbing sponge has the hole and bubble of inside and outside connection, when sound wave is injected into sponge, causes gap hollow
Gas vibrates, and due to the viscosity resistance of air, air generates friction with gap hole wall so that most of acoustic energy be converted to thermal energy and by
Consumption, remaining sound wave gradually decreases on the surface that wave crest sound-absorbing sponge rises and falls by refraction repeatedly, in addition when air is exhausted
During hot compression, heat exchange constantly occurs between air and gap hole wall, also part acoustic energy can be made to be converted to thermal energy, so as to further
Achieve the effect that sound-absorbing；
2nd, with motor long-play, internal carbon brush can generate carbon dust, carbon dust since main component is carbon
It is blown in air duct from air outlet, sponge is due to the gentle puff of hole to the effect of filtering carbon dust；
3rd, air outlet is equipped with the scattered type silencer of through-hole resistance, can effectively weaken the noise at air outlet；
4th, motor periphery wall is coated with heat radiation coating, improves the heat dissipation of motor；
5th, third wave crest sound-absorbing sponge is equipped with a fixed plate towards air duct lower flow channel face, and through-hole is provided in fixed plate, fixed
Plate plays the role of fixed third wave crest sound-absorbing sponge, and because there is through-hole, fixed plate does not hinder the wind after filtering.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description.
Embodiment one, the present invention provide a kind of mute ducting system of dust catcher, as shown in Figure 1, it includes fan housing 1, wind turbine
2nd, motor 3 and air duct 4, fan housing 1 and air inlet 5 form air intake vent channel, suck air from air intake vent channel, wind turbine 2 is located at wind
In cover 1, motor 3 is connected with wind turbine 2, and 4 one end of air duct is connected with wind turbine 2, and the other end is wind passage mouth 12, and motor 3 is located in air duct 4
And equipped with air outlet 6.3 periphery wall of motor is around wave first peak sound-absorbing sponge 7,8 direction of wave crest face of primary peak sound-absorbing sponge 7
3 periphery wall of motor, the sound wave that motor 3 generates are injected in primary peak sound-absorbing sponge 7, have because of primary peak sound-absorbing sponge 7 in
The hole and bubble of outer connection, sound wave cause air vibration in gap, and air generates friction with gap hole wall so that most of sound
Thermal energy can be converted to and be consumed；In addition, a part of sound wave passes through folding repeatedly on the surface that primary peak sound-absorbing sponge 7 rises and falls
It penetrates and gradually decreases；When air adiabatic compresses, heat exchange constantly occurs between air and gap hole wall, can also make part acoustic energy
Thermal energy is converted to, so as to further achieve the effect that sound-absorbing；4 internal perisporium of air duct is equipped with secondary peak sound-absorbing sponge 9, and the second wave
The wave crest face 8 of peak sound-absorbing sponge 9 is made an uproar towards in air duct 4 from the wind that 3 air outlet 6 of motor comes out by generating wind during air duct 4, wind
Noise waves are injected in secondary peak sound-absorbing sponge 9, and 9 principle of noise reduction of secondary peak sound-absorbing sponge is removed with primary peak sound-absorbing sponge 7
Noise Reduction, primary peak sound-absorbing sponge 7 and secondary peak sound-absorbing sponge 9 also act as the effect of filtering carbon dust；By second
Wave crest sound-absorbing sponge it is distinguished and admirable to wind passage mouth 12, the third wave crest sound-absorbing sponge 10 on wind passage mouth 12 further functions as noise reduction
And the effect of filtering carbon dust.
It advanced optimizes, as shown in Fig. 2, 8 shape of wave crest face is sinusoidal waveform or pyramid or wedge shape, to high frequency
Absorbability is very strong, and can good buffering vibration, protect equipment, with motor 3 operate and the heat that generates, motor 3
Temperature constantly increases, fire-retardant characteristic, can effectively avoid hidden danger on fire, it is ensured that 3 safe operation of motor, in addition because of wave crest face 8
Shape is in undulated, and the wind come out from air outlet 6 contacts area increase, so as to enhance filtering carbon dust ability.
It advanced optimizes, 3 periphery wall of motor is coated with heat radiation coating, is a kind of radiating efficiency for improving 3 surface of motor, drops
The sapecial coating of low temperature ensures that motor 3 is in the temperature of safety and operates.
It advanced optimizes, air outlet 6 is equipped with through-hole resistance and dissipates type silencer, and principle is dropped using sound-absorbing porous material
Low noise, when sound wave enters muffler, a part of acoustic energy rubs in the hole of porous material and is converted to thermal energy consumption and dissipates,
Make to weaken by the sound wave of muffler, reach noise reduction purpose.
It advanced optimizes, third wave crest sound-absorbing sponge 10 is fixed on by fixed plate 11 at wind passage mouth 12.
Embodiment two, 10 two sides of third wave crest sound-absorbing sponge are all wave crest face 8, and fixed plate 11 is between two wave crest faces 8
And be fixed on 4 inner wall of air duct, remaining is the same as embodiment one.
Embodiment three, third wave crest sound-absorbing sponge 10 are equidistantly set layer by layer along 4 inner wall of air duct, correspondingly, fixed plate 11
Also it is equidistantly fixed on layer by layer on 4 inner wall of air duct, remaining is the same as embodiment one.
Preferred embodiments of the present invention are described above, but are not to be construed as limiting the scope of the invention.This hair
Bright to be not only limited to above example, concrete structure is allowed to vary, as air duct shape is not only limited to folding as shown in Figure 1
Bending shape and length can also be irregular shape etc., all various changes made in the protection domain of demand for independence of the present invention
Within the scope of the present invention.
