Water drain corrosion-proof system, water drain corrosion-proof silencer and water drain corrosion-proof method

Abstract

The present invention relates to a draining and rust-preventing system, a draining and rust-preventing muffler and a draining and rust-preventing method. The muffler comprises a muffling chamber, a pressure storage tank, an output channel, a controller and a drainage-executing mechanism; wherein, an exhausting pipe is inserted in the muffling chamber; the pressure storage tank is communicated with the muffling chamber through an one-way channel; the output channel is communicated with the pressure storage tank and can output the air in the pressure storage tank; the controller can control theopening and closing of the output channel; and the startup of the drainage-executing mechanism is driven by the air outputted from the output channel. Through the one-way channel, the pressure storage tank can bring in and store the air with a certain pressure coming from the muffling chamber, and the muffling chamber is provided with at least one drain hole, which can be closed or opened by the drainage-executing mechanism. The present invention utilizes the controller to transfer the pressure stored in the pressure storage tank to the drainage-executing mechanism, which then utilizes the air pressure to control the opening and closing of the drain holes of the muffler, so that the interior drainage function of the muffler can be fulfilled, and thereby, the water accumulation problem of the muffler can be thoroughly resolved. The muffler has a reasonable structure and can automatically utilize the air pressure to drain water.

Description

technical field [0001] The invention relates to a motor vehicle exhaust system, and more specifically relates to a drainage anti-corrosion system using air pressure for drainage, a drainage anti-corrosion muffler and a drainage anti-corrosion method. Background technique [0002] According to the combustion products of the engine, it is normal to have water vapor in the exhaust of motor vehicles (especially automobiles). When the temperature is low, there will be water in the exhaust pipe or at least water vapor will emerge. Water accumulation is a normal phenomenon. Since the muffler is a sealed structure, long-term water accumulation will cause the muffler to rust, eventually leak, and freeze the exhaust pipe in winter. [0003] For the current common situation of water accumulation in the exhaust pipe, there are some countermeasures: [0004] 1. Internal design of the muffler [0005] Through the design of the outlet inner pipe of the muffler, such as the direction and ...

Problems solved by technology

[0007] 2) When the temperature is relatively low, if the parking time is relatively long, the accumulated water in the exhaust pipe and muffler will freeze and block the exhaust pipe, making it difficult to start the car

[0008] 3) In the rainy season, due to parking in the rain and other reasons, rainwater or accumulated water will be poured into the muffler, and the exhaust port of the muffler is generally higher than the muffler shell due to design problems, so the accumulated water often cannot flow out completely

[0012] After parking, slam on the accelerator to drain water, or change gears at high speed during driving, and use inertia to discharge the water deposited inside, but this is not a long-term solution
