Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.
In prior art air inlet system, because connecting tube is arranged between suction tude resonant cavity, there is the problem large, structure is not compact that takes up room.For solving the problem of prior art, the utility model proposes a kind of air inlet system that is little, compact structure that takes up room, described air inlet system comprises: the connecting tube of suction tude, resonant cavity, connection suction tude resonant cavity, described connecting tube is inserted in described resonant cavity at least partly.
Compared with prior art, when connecting tube has equal length, air inlet system of the present utility model is by being inserted in connecting tube at least partly in resonant cavity, not only there is the effect of noise decrease, and the length of the connecting tube between suction tude and resonant cavity can be reduced, have compressed taking up room of connecting tube, thus air inlet system entirety is taken up room reduction, structure is compacter.
Refer to Fig. 2, Fig. 2 is the generalized section of air inlet system first mode of execution of the present utility model.Air inlet system comprises suction tude 1, resonant cavity 2 and is communicated in the connecting tube 3 of suction tude 1 resonant cavity 2.Wherein, resonant cavity 3 comprises near the superstructure of suction tude 1 and the substructure away from suction tude 1, and superstructure is connected in a welding manner with substructure.Superstructure has an opening, and connecting tube 3 is inserted in resonant cavity 2 inside at least partly by this opening removably or in a welding manner.By being inserted at least partly in resonant cavity 2 by connecting tube 3, the length of the connecting tube 3 between suction tude 1 and resonant cavity 2 being reduced, have compressed taking up room of connecting tube, thus air inlet system entirety is taken up room reduction, structure is compacter.
Refer to Fig. 3, Fig. 3 is the generalized section of air inlet system second mode of execution of the present utility model.Air inlet system comprises suction tude 1, first resonant cavity 21, second resonant cavity 22, is communicated in the first connecting tube of suction tude 1 and the first resonant cavity 21 and is communicated in the second connecting tube of suction tude 1 and the second resonant cavity 22.Wherein, first connecting tube comprises the first pipeline section 31 in the first resonant cavity 21 and the second pipeline section 32 between the first resonant cavity 21 and suction tude 1, second connecting tube comprises the 3rd pipeline section 33 of in the second resonant cavity 22 and the 4th pipeline section 34 between the second resonant cavity 22 and suction tude 1, wherein, second pipeline section 32 and the 4th pipeline section 34 have identical length, and the first pipeline section 31 and the 3rd pipeline section 33 have different length.Frequency of noise elimination due to resonant cavity follows the length of the volume of cavity and connecting tube relevant, and volume is different, and length is different, and the frequency of noise elimination of resonant cavity is different.Therefore, multiple resonant cavity is provided with in present embodiment, and the connecting tube length being positioned at each resonant cavity is different, length between resonant cavity with connecting tube is identical, setting like this not only have compressed taking up room of connecting tube, but also the noise of multi-frequency can be reduced, make frequency of noise elimination coverage area wider, thus better anti-noise effect can be reached.
Be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, technological scheme in each mode of execution also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
A series of detailed description listed is above only illustrating for feasibility mode of execution of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.
