Efficient exhaust pipe device

Abstract

The invention relates to an efficient exhaust pipe device which 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 part of the main exhaust pipe and is in an inverted U shaped; two pipe orifices of the lower part of the auxiliary exhaust pipe are connected with the main exhaust pipe; the electromagnetic valve is arranged at the middle part of the main exhaust pipe and is also arranged between the two pipe orifices of the lower part of the auxiliary exhaust pipe; the electromagnetic valve controls conduction and closing of the middle part of the main exhaust pipe; the silencer is connected to one end of the main exhaust pipe; an iron gauze is arranged at the connecting part of the silencer and the main exhaust pipe; and an electrostatic neutralizer is arranged on the main exhaust pipe and is used for neutralizing static electricity in the main exhaust pipe. Compared with the prior art, the efficient exhaust pipe device is of a simple structure, is good in waterproof effect and heat dissipation and high in exhaust efficiency and can resist rats.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an efficient 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 ...

Problems solved by technology

[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 is easy to touch the exhaust pipe if you do not pay attention, and it is easy to damage the exhaust pipe. Injuries caused by accident; moreover, after a long period of use, the drainpipe is easy to form debris accumulation, which affects the exhaust efficiency
