Waterproof exhaust pipe device

Abstract

The invention relates to a waterproof exhaust pipe device. The waterproof exhaust pipe device comprises a main exhaust pipe, an auxiliary exhaust pipe, an electromagnetic valve and a silencer. The auxiliary exhaust pipe is arranged at the upper end of the middle of the main exhaust pipe and is in the shape of an inverted U, and the lower two pipe ports of the auxiliary exhaust pipe are connected with the main exhaust pipe; the electromagnetic valve is arranged in the middle of the main exhaust pipe and between the lower two pipe ports of the auxiliary exhaust pipe and controls the opening and closing of the middle of the main exhaust pipe; the silencer is connected at one end of the main exhaust pipe, and the connecting portion between the silencer and the main exhaust pipe is provided with a gauze screen. Compared with the prior art, the waterproof exhaust pipe device is simple in structure, good in waterproof effects and heat dissipating effects and mouseproof.

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
