As depicted in figs. 1 and 2, in one embodiment, a kind of air filter noise reduction processing mechanism, comprising: air inlet ontology
100, separator 200 and communicating pipe 300.Inlet plenum 110 is offered inside the air inlet ontology 100, the separator 200 fills
It is located inside the inlet plenum 110, and the inlet plenum 110 is divided into the first noise reduction chamber 111 by the separator 200
With the second noise reduction chamber 112.The communicating pipe 300 is installed on the separator 200, and the inlet end of the communicating pipe 300
In the first noise reduction chamber 111, the outlet side of the communicating pipe 300 is located in the second noise reduction chamber 112.
Above-mentioned air filter noise reduction processing mechanism when in use, first according to the shape of air filter or shape, determines that gas exists
Air inlet sounding frequency range inside inlet plenum 110.Wherein, when the expansion penetration distance inside inlet plenum 110 changes,
Sounding frequency range inside inlet plenum 110 can change, so that gas is formed in inlet plenum 110 and air inlet
The corresponding reflection sounding frequency range of sound wave frequency range, realizes the counteracting of sound wave.According to air inlet of the gas inside inlet plenum 110
Sounding frequency range determines installation site of the separator 200 inside inlet plenum 110.At this point, being separated out first by separator 200
Noise reduction chamber 111 and the second noise reduction chamber 112, gas carry out the noise elimination of sounding frequency range in the first noise reduction chamber 111 first, so
Afterwards, gas is eliminated the noise by communicating pipe 300 into the second noise reduction chamber 112 again.Therefore, above-mentioned air filter noise reduction processor
Structure can effectively be handled sound.
Specifically, in the present embodiment, separator 200 is isolation board or spacer, separator 200 and air inlet ontology 100
The first noise reduction chamber 111 for surrounding of a portion side wall.Gas initially enters the first noise reduction chamber 111, at this point, gas exists
Into air inlet sound can be generated during the first noise reduction chamber 111, meanwhile, gas will do it stream in the first noise reduction chamber 111
Dynamic, air inlet sound is reflected under the expansion penetration distance of the first noise reduction chamber 111, so as to generate and air inlet sound same frequency
The reflected sound of section, reflected sound are propagated in opposite directions with air inlet sound, realize sound in the noise elimination of the first noise reduction chamber 111.Further,
Gas can enter the second noise reduction chamber 112 by communicating pipe 300, at this time since second disappears after 111 noise reduction of the first noise reduction chamber
Sound chamber 112 is different from the volume of the first noise reduction chamber 111, therefore, expansion penetration distance inside the second noise reduction chamber 112 with
Expansion penetration distance inside first noise reduction chamber 111 is not identical, i.e., gas enters the first noise reduction chamber 111 and the second silencing cavity
Behind room 112, gas can generate the reflected sound of two frequency ranges, offset the air inlet sound of gas by the reflected sound of two frequency ranges at this time,
Reflected sound can be greatly improved to the neutralization of air inlet sound, that is, improve the noise reduction effect of above-mentioned air filter noise reduction processing mechanism
Fruit.
Further, when the expansion penetration distance inside inlet plenum 110 changes, inside inlet plenum 110
Sounding frequency range can change so that gas formed in inlet plenum 110 it is corresponding with air inlet sound wave frequency range
Reflection sounding frequency range.When the expansion area ratio of gas changes (when referring to that gas passes through the outflow of different openings area, gas
Sonic wave amplitude can change), the sonic wave amplitude inside inlet plenum 110 can change so that gas into
Reflected acoustic wave amplitude corresponding with air inlet sonic wave amplitude is formed in gas chamber 110, that is, is formd and air inlet sound wave sounding frequency range
And the reflected acoustic wave that sonic wave amplitude is all the same, realize the counteracting of sound wave.Specifically, in the present embodiment, by changing air inlet
The opening size of mouth can change sonic wave amplitude of the gas inside the first noise reduction chamber 111, change the open-mouth ruler of communicating pipe 300
The very little sonic wave amplitude that can change gas inside the second noise reduction chamber 112.
