It includes a liquid collection pipe arranged in the tank body and used to absorb residual liquid, a sewage valve arranged on the outer peripheral wall of the tank body, and a collecting pipe connected to a collecting piece. The collecting pipe and the liquid collection pipe are respectively sealed and connected to the sewage valve, and one end of the liquid collection pipe away from the sewage valve is located at the lower part of the tank body; the pressure inside the tank body is greater than the pressure inside the collecting pipe. When the sewage valve is in an open state, due to the presence of a large amount of gas such as saturated vapor of propane inside the tank body, the pressure inside the tank body is greater than the pressure difference formed by the pressure in the liquid collection pipe. The pressure in the tank body can press the residual liquid at the bottom of the tank body into the liquid collection pipe, and the residual liquid flows to the collecting piece through the liquid collection pipe, the sewage valve, and the collecting pipe in turn for collection. The present application has the effect of facilitating the user to discharge the residual liquid.
