Abstract
The invention discloses an air filter integrated with an internally-inserted pipe. The air filter comprises an air inlet side expansion cavity which is communicated with an air inlet pipe, a filter core, and an air outlet side cavity which is communicated with an air outlet pipe, wherein the air outlet pipe is communicated with the air outlet side cavity through the internally-inserted pipe; the air inlet end of the internally-inserted pipe is positioned in the air outlet side cavity; the air inlet end of the internally-inserted pipe is flared, and is over against the filter core of the air filter; the air outlet end of the internally-inserted pipe is connected with the air inlet end of the air outlet pipe. By adopting the air filter, the noise can be reduced, and the resistance loss of air current can be reduced.
Description
Technical field
The present invention relates to the structure of air filter of automobile, relate to a kind of air filter being integrated with interpolation pipe in particular.
Background technique
Existing air filter being provided with the silencer element for eliminating the noise, being provided with the honeycomb duct for water conservancy diversion in addition, but do not play the pipeline of water conservancy diversion and noise elimination effect simultaneously.The effect of silencer element reduces noise, and the effect of honeycomb duct reduces resistance, but reduce resistance and reduce noise to be two paradox.The general interpolation pipe that increases in air filter cavity all can form inhibition to air flowing to reduce noise, thus increases the resistance of whole air filter system.
The external structure of existing air filter and the structure of Fig. 1 similar, shown in Fig. 1 and Fig. 4, existing air filter comprises the air inlet side expansion chamber 21, filter core 22 and the side cavity 23 of giving vent to anger that is communicated with steam outlet pipe 3 that are communicated with suction tude 1.Air draught enters air inlet side expansion chamber 21 by suction tude 1, after filter core 22 filters, then is incorporated in motor through steam outlet pipe 3 by side cavity 23 of giving vent to anger.Air draught is when directly entering steam outlet pipe 3 by side cavity 23 of giving vent to anger, and because airflow cross section diminishes suddenly, change in flow is too large, without any in water conservancy diversion situation, drag losses is increased, forms larger noise simultaneously, thus the requirement of motor to intake resistance and noise cannot be met.
Summary of the invention
The object of this invention is to provide a kind of air filter being integrated with interpolation pipe, it can not only reduce noise, but also can reduce the drag losses of air-flow.
The air filter being integrated with interpolation pipe of the present invention, the side cavity and at air inlet side expansion chamber and the filter core of giving vent to anger between the cavity of side of giving vent to anger comprising that the air inlet side expansion chamber that is communicated with suction tude is communicated with steam outlet pipe, described steam outlet pipe is communicated with by interpolation pipe with giving vent to anger between the cavity of side; Give vent to anger described in the inlet end of interpolation pipe is positioned at side cavity, the inlet end of interpolation pipe is bell mouth shape, and just to the filter core of air filter; The outlet side of interpolation pipe is connected with steam outlet pipe inlet end.
Further, described interpolation pipe is connected in sequence by horn mouth, honeycomb duct and connecting tube.
Further, the external diameter of described connecting tube equals the internal diameter of steam outlet pipe inlet end, and connecting tube is positioned at steam outlet pipe inlet end, is made that interpolation pipe and steam outlet pipe are airtight to be connected by clip, avoids interpolation pipe and steam outlet pipe joint preferably and produces and leak gas.
During use, air draught enters air inlet side expansion chamber by suction tude, after filter element filtering, enters honeycomb duct, enter steam outlet pipe, be incorporated in motor by connecting tube by the interpolation pipe horn mouth water conservancy diversion of interpolation pipe.
The air filter being integrated with interpolation pipe of the present invention, interpolation pipe is had owing to increasing, steam outlet pipe is entered by horn mouth water conservancy diversion by the air of filter core, reduce the loss of resistance, air-flow is seamlessly transitted by horn mouth, avoid side cavity of giving vent to anger to diminish suddenly to steam outlet pipe airflow cross section, thus reduce the noise of air filter.Structure of the present invention is simple, with low cost, changes less, but serve good effect for original structure.Present invention reduces intake resistance, thus improve engine operating efficiency and life-span; Reduce engine noise, improve motor sound quality.Analyzed by automobile CFD, specify that the length of interpolation pipe, particular location and bell-mouthed shape size, different automobile types also can carry out corresponding optimal design according to the layout in space.
