Abstract

The invention relates to the technical field of automobiles, in particular to a gas discharging device. The gas discharging device comprises a valve body and a casing; the valve body is used for beingarranged in a cavity of the fuel tank; a wall plate of the valve body is connected with a wall plate of the fuel tank; a cavity of the valve body is communicated with the cavity of the fuel tank; thecasing is positioned above the valve body in a vertical direction; a bottom plate of the casing is connected with the wall plate of the valve body; a through hole is formed in the bottom plate of thecasing; a cavity of the casing is communicated with the cavity of the valve body through the through hole; and a joint for being connected with a pipeline is arranged on the upper part of the casing.The gas discharging device integrates the casing for storing leaked fuel and the fuel tank into a whole structure, the fuel tank and a carbon tank are communicated through one pipeline, and two joints are arranged between the pipeline and a liquid collector, so that a connecting structure between the fuel tank and the carbon tank is more stable, and the risk that gas leakage exists, even the pipeline is separated in the joint position caused by vibration is reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an exhaust device, a fuel tank and an automobile. Background technique [0002] The fuel tank is an important component of the car and is used to store fuel. Because the fuel is volatile, the fuel tank will be filled with evaporated gas, so the pressure in the fuel tank will increase accordingly. In order to balance the pressure in the fuel tank and avoid danger, an exhaust pipe is arranged on the fuel tank, and the fuel vapor is discharged into the outside atmosphere through the exhaust pipe. However, fuel vapor will reduce air quality and pollute the environment, and direct discharge of fuel vapor will also cause waste of resources. [0003] In order to solve the above problems, a carbon canister is arranged between the fuel tank and the engine in the prior art, and activated carbon with strong adsorption capacity is filled in the carbon canister; after the gas in the fue...
