Problems solved by technology

When arranging, it is necessary to install an absorption-type intake muffler on the inlet pipe. The intake muffler is to arrange a certain number of round holes with a certain diameter on the outer periphery of the air filter inlet pipe. The airtight chamber forms the intake muffler, because it is difficult to ensure sealing and ventilation at the same time in the structure, so the effect is very poor

Embodiment Construction

[0010] see figure 1 , the structure of the present invention is formed by the combination of two parts of the pipe body A and the pipe body B, wherein the joint part of the pipe body A is integrally formed with a convex shape muffler cavity 1, and the joint part of the pipe body B is formed on the pipe wall The round holes 2 are evenly arranged, and after being inserted into the junction of the pipe body A, it can just seal the muffler cavity 1, that is, it is combined with the muffler cavity 1 to form an intake muffler, and a circle is integrally formed outside the pipe body B The sealing edge 3 is connected to coincide with the adjacent outer wall of the muffler cavity 1, and is welded or bonded to each other to realize sealing and positioning.

Abstract

The present invention relates to an air filter intake pipe structure of engine. It is made up by combining two pipe bodies. The combined portion of pipe body A is made into the form of integrally-formed outwards-projected silencer cavity, on the pipe wall of combined portion of pipe body B several circular holes are uniformly distributed, the combined portion of pipe body A is inserted, the silencer cavity just can be sealed, said combined portion and the silencer cavity can be commonly formed into intake silencer, and on the exterior of said pipe body B a turn of connecting seal edge can be integrally-formed.

Description

technical field [0001] The invention relates to the air filter technology of an automobile engine. Background technique [0002] The air filter inlet pipes of automobile engines used in the market are all independent rubber pipes or plastic pipes. When arranging, it is necessary to install an absorption-type intake muffler on the intake pipe. The intake muffler is to arrange a certain number of circular holes with a certain diameter on the outer periphery of the air filter intake pipe, and arrange a certain volume at the circular hole. The airtight cavity forms the intake muffler, and the effect is very poor because it is difficult to ensure sealing and ventilation at the same time in structure. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide an air filter inlet pipe structure of the engine with simple structure and good sealing performance. ...
