Problems solved by technology

[0002] At present, the toilet feces widely used in passenger trains flow directly to the roadbed through the defecation pipe, which consumes a lot of water. With the continuous increase of the train speed, the feces that flow down are blown up by the wind, seriously polluting the train compartment, corroding the train chassis, and affecting The train is running safely, and at the same time, if the scraped feces enter the compartment, it will endanger the health of passengers

Abstract

The toilet excrement discharge system for high speed train includes urinal, water jet, two pneumatic valves, small container, vacuum generator, solenoid valves, button, emergency switch, small water tank, electromagnetic water valve, vacuum and pressure detecting unit, etc. The urinal is flushed with jetted water in small quantity, and excrement is concentrated in the bottom of the urinal and vacuum sucked into one small container before pressurized to jet to railway bed via the discharge port or to the large container in the lower part of the train. The present invention can avoid blowing of excrement, reduce train pollution and rust and ensure safe running of the train and the health of passengers. The technology of the present invention may be used also in coach bus, hotel in water-lacking area, etc.

Description

Technical field [0001] The invention relates to a high-speed train toilet excrement discharge system. Background technique [0002] At present, the toilet feces widely used in passenger trains flow directly to the roadbed through the defecation pipe, which consumes a lot of water. With the continuous increase of the train speed, the feces that flow down are blown up by the wind, seriously polluting the train compartment, corroding the train chassis, and affecting The train runs safely, and the excrement blown up simultaneously enters the compartment, endangering the health of passengers. Contents of the invention [0003] The object of the present invention is to provide a feces discharge system for high-speed train toilets, which uses high pressure to spray a small amount of water to flush the urinal so that the feces are concentrated at the bottom of the urinal, and vacuumizes the feces into a small container Then pressurize to make the feces spray from the system disch...
