Description
technical field [0001] The invention relates to the field of railway train feces collection systems. Background technique [0002] As the country has higher and higher requirements on the environmental protection and sanitation of railway passenger trains, the direct discharge of feces from passenger trains in the past will be gradually banned. At present, the structure of the excrement collection system for railway trains is relatively complicated and the cost is high, which is not conducive to popularization and promotion on railway trains. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a railway train excrement collection system that can be used and popularized on trains. For this reason, the present invention adopts the following technical solutions: it includes a toilet and a dirt box, and the system is also provided with a vacuum device for the dirt box; the system is also provided with a water booster, a...
