A waterproof exhaust pipe device

Abstract

The invention relates to a waterproof exhaust pipe device, which includes a main exhaust pipe, an exhaust auxiliary pipe, a solenoid valve and a muffler. The exhaust auxiliary pipe is placed at the upper end of the middle part of the exhaust main pipe. Inverted U-shaped, the lower two nozzles of the auxiliary exhaust pipe are connected to the main exhaust pipe; the solenoid valve is placed in the middle of the main exhaust pipe, and the solenoid valve is located Between the ports, the electromagnetic valve controls the conduction and closure of the middle part of the exhaust main pipe; the muffler is connected to one end of the exhaust main pipe; the connection between the muffler and the exhaust main pipe is provided with iron gauze. Compared with the prior art, the invention has the advantages of simple structure, good waterproof effect, good heat dissipation effect, and can prevent rats.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a waterproof exhaust pipe device. Background technique [0002] Most of the existing automobile exhaust devices are mufflers lying under the longitudinal beams, or arranged on the outside of the frame, but these arrangements have always had the problem that the exhaust port is easy to enter water, especially when it rains in summer, many roads are prone to water accumulation , causing the vehicle to be impassable, if the vehicle forcibly fords water, the water reaching a certain depth will enter the engine through the exhaust pipe, causing the engine to stall, and when it is re-ignited, it is also prone to engine explosion, which will bring unnecessary damage. The situation is serious and will cause personal injury or death; the exhaust pipe will become relatively hot after the car has been running for a period of time. Since many exhaust pipes are exposed outside the car, it ...

[0002] Most of the existing automobile exhaust devices are mufflers lying under the longitudinal beams, or arranged outside the frame, but these arrangements have always had the problem that the exhaust port is easy to enter water, especially when it rains in summer, many roads are prone to water accumulation , causing the vehicle to be impassable, if the vehicle is forcibly wading through water, the water reaching a certain depth will enter the engine through the exhaust pipe, causing the engine to stall, and the engine will easily burst when it is re-ignited, causing unnecessary damage. The situation is serious and will cause personal injury or death; the exhaust pipe will become relatively hot after the car has been running for a period of time. Since many exhaust pipes are exposed outside the car, it is easy to touch the exhaust pipe if you do not pay attention, and it is easy to damage the exhaust pipe. man inflicted injury
