Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, embodiment described herein only is used for description and interpretation the present invention, is not limited to the present invention.
In the present invention, Fig. 1 is the schematic diagram of the suction tude of prior art, and Fig. 2 is the schematic diagram of the preferred implementation of suction tude of the present invention.The entrance of the suction tude in two figure all on the right, the left side for the outlet.
The invention provides a kind of suction tude, this suction tude is connected with the air-strainer of automobile, and wherein, this suction tude comprises eddy flow pipeline section 1, noise reduction pipeline section 2 and the air guide pipeline section 3 that connects successively, wherein
This eddy flow pipeline section 1 is used for filtering the impurity of charge air flow;
This noise reduction pipeline section 2 is for reducing induction noise;
This air guide pipeline section 3 is communicated with described air-strainer, is used for the charge air flow that described noise reduction pipeline section 2 flows out is imported described air-strainer.
Different from the suction tude that mainly plays the air-flow leading role in prior art, suction tude of the present invention has a plurality of pipeline sections that have respectively difference in functionality.Wherein, eddy flow pipeline section 1 is used for filtering the impurity of charge air flow, and noise reduction pipeline section 2 is for reducing the noise of air inlet, and air guide pipeline section 3 is used for the guiding of charge air flow.
The present invention limits in this function to each pipeline section, and each pipeline section is realized that the means of above-mentioned functions are not limited.And any applicable method may be used to realize above-mentioned purpose in the present invention, the objective of the invention is to protect the suction tude that realizes difference in functionality by different pipeline sections is set, and the means of each pipeline section practical function are not limited.
For example, the purpose of eddy flow pipeline section 1 is charge air flow is carried out pre-filtering, can utilize the modes such as air filter screen or extra electric field to realize; The purpose of noise reduction pipeline section 2 is to reduce the induction noise of charge air flow, can utilize on the inwall of this pipeline section to form projection or to utilize the mode such as sound absorbing material to realize.
Below only each pipeline section of suction tude of the present invention is realized that the means of its function simply exemplify, thereby the suction tude that technological scheme of the present invention is protected is supported fully, and be not that its mode of execution is limited to this.The mode of execution that below will introduce is the preferred implementation of suction tude of the present invention.
Pass through technique scheme, suction tude of the present invention comprises eddy flow pipeline section, noise reduction pipeline section and the air guide pipeline section that connects successively, wherein the eddy flow pipeline section filters charge air flow, and the noise reduction pipeline section reduces induction noise, and the charge air flow that flows through the noise reduction pipeline section flows into air-strainer by the guiding pipeline section.Suction tude of the present invention not only effectively reduces induction noise, can also improve the dust containing capacity of gas handling system, and has compact structure, and weight is lighter, and the characteristics of being convenient to assemble easily realize industrialization.
Preferably, the entrance of described eddy flow pipeline section 1 is provided with a plurality of rotation blades 12 regularly.In addition, preferably, the entrance of described eddy flow pipeline section 1 is provided with airstrainer.
More than exemplified the preferred implementation of two kinds of eddy flow pipeline sections 1.Airstrainer is a kind of fairly simple air-filtering mode commonly used, installs airstrainer additional to improve airfiltering effect on the suction tude before air-strainer, improves the quality of charge air flow, can protect better motor.

Preferably, described inner wall layer is formed by the cotton thread braiding.Not only cost is lower for the inner wall layer of cotton thread braiding, is convenient to assembling, and material softness, is conducive to reduce noise.
Preferably, be threaded connection between described eddy flow pipeline section 1 and/or described noise reduction pipeline section 2 and/or described guiding pipeline section 3.
Because each pipeline section of suction tude of the present invention has respectively separately function, therefore usually form respectively and then fit together.And suction tude of the present invention is made by plastic materials etc. usually.Therefore preferably adopt the mode that is threaded to link together between each pipeline section, form respectively the screw thread that cooperatively interacts on the inner and outer wall of two pipeline sections that are connected, be threaded by this and can be directly the body of pipeline section be linked together, easy accessibility not only, and do not need extra link, simple in structure.
Certainly, can connect by other means between each pipeline section, such as form the modes such as hole of passing link at tube wall, the present invention is not limited this.
Air guide pipeline section 3 in suction tude of the present invention plays the effect of air-flow guiding, because the mode of execution that is applicable to air guide pipeline section 3 of the present invention much also is readily appreciated that, its structure is not limited and introduces at this.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned mode of execution; in technical conceive scope of the present invention; can carry out multiple simple variant to technological scheme of the present invention, these simple variant all belong to protection scope of the present invention.
Need to prove in addition, each concrete technical characteristics described in above-mentioned embodiment in reconcilable situation, can make up by any suitable mode, for fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible compound modes.
In addition, also can carry out combination in any between various mode of execution of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
