Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the application of the automobile engine muffler drainage device in the prior art is limited by the structure of the muffler, and to provide a vehicle muffler that can flexibly control the pressure difference at both ends of the suction pipe, even at the water inlet and outlet of the drain pipe. When the height difference of the nozzle is large or the viscous resistance of the stagnant water is large, the drainage device of the muffler can also effectively remove the stagnant water in the muffler chamber

Abstract

The present invention relates to an automotive muffler. The muffler comprises an air inlet pipe, an air outlet pipe (5) and a muffling cavity (1), and wherein, the air inlet pipe and the air outlet pipe (5) are connected with the muffling cavity (1). The muffler also comprises a drainage, which comprises a choke tube (2) and a suction tube (24); wherein, the choke tube (2) comprises a first part (21), a second part (22) and a third part (23) which are orderly communicated with one another; the sectional area (A1) of the first part (21) is less than the sectional area (A2) of the second part (22); and moreover, relative to the sectional area (A1) of the first part (21), the sectional areas of the connected parts of the second part (22) and the first part (21) are abruptly expanded. The automotive muffler can flexibly control the pressure difference of both ends of the suction tube (24), and the accumulated water in the muffling cavity can be effectively removed.

Description

technical field [0001] The invention relates to a muffler, more specifically, to a vehicle muffler. Background technique [0002] The muffler is an important part of the automobile exhaust system. The design, manufacture and daily maintenance of the muffler are extremely important to the muffler's muffler effect, the exhaust pipe and the service life of the muffler. The muffler usually includes an inlet pipe, an outlet pipe and a muffler chamber. After the gas mixed with fuel is burned in the combustion chamber of the engine, a part of water vapor will be produced, which will be discharged through the exhaust system of the car, that is, it will first enter the exhaust pipe of the exhaust system, and then enter the muffler chamber of the muffler through the intake pipe of the muffler. After muffler, it enters the exhaust tailpipe of the exhaust system through the outlet pipe of the muffler, and finally exhausts to the atmosphere through the exhaust tailpipe. Because the temp...
