Embodiment Construction
[0012] In the accompanying drawings, an automatic drainage device for an automobile exhaust pipe includes an exhaust pipe 1, and the two ends of the exhaust pipe 1 are respectively provided with an air inlet 2 and an air outlet 6; the pipe body of the exhaust pipe 1 The bottom is provided with a drainage hole 5; the drainage hole 5 is blocked by an arc-shaped shrapnel 4 that expands with heat and contracts with cold;
[0013] One end of the arc-shaped single piece 4 is connected to the mounting frame 3, and the outer arc surface of the other end is closely attached to the wall of the exhaust pipe 1. When the exhaust pipe 1 is working, its internal temperature rises, and the arc-shaped shrapnel 4 Thermal expansion and elongation block the drain hole 5. After the car stops, the temperature in the exhaust pipe will gradually decrease due to the engine stopping. discharge.
[0014] The mounting frame 3 is a semi-closed type, which can not only protect the drain hole 5 to a certai...

The invention relates to an automatic draining device of a vehicle exhausting pipe. The automatic draining device comprises an exhausting pipe, wherein an air inlet and an air outlet are respectively formed in the two ends of the exhausting pipe; a drain hole is formed in the bottom of the pipe body of the exhausting pipe and is blocked by an arc spring plate which expands in case of heat and contracts in case of cold; the arc spring plate is connected with a mounting frame arranged on the wall of the exhausting pipe. The drain hole is formed in the exhausting pipe, the closing state between the arc spring plate and the drain hole is adjusted through temperature, and water in the exhausting pipe is timely drained through the drain hole, so that the problems of the air leakage and high noise of the exhausting pipe of the current vehicle, caused by corrosion, are solved, the service life of the exhausting pipe is prolonged, and money is saved for a user.
Description
technical field [0001] The invention relates to an automatic drainage device for an automobile exhaust pipe. Background technique [0002] With the improvement of people's living standards, cars have entered thousands of households, but the engine exhaust pipes of automobiles are frequently damaged, and some have to be replaced once a year. There is still a lot of water in the exhaust pipe that has not been discharged, which causes the bottom end of the exhaust pipe to be damaged due to long-term corrosion and air leakage, which brings inconvenience to people using the car and increases road noise pollution and exhaust pipe damage. The replacement frequency reduces the service life of the automobile exhaust pipe, thus causing a waste of user funds. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an automatic drainage device for automobile exhaust pipes. Drainage holes are arranged on the exhaust pipe, and the closed ...
