Abstract

This invention relates to a blow-off device in the lavatory of train carriages including a bed pan, a channel conducting to the bed pan, a dirt storage box and a controlled valve mounted at the outlet of the box. Advantages: the controller controls the open and close of the controlled valve, 2, the controller controls the speed of the open or close of the controlled valve to control discharging dirt slowly or quickly, 3, the controller of the controlled box is installed out of the lavatory easy to be operated by the train attendants, who discharge them away from the station or quickly to a place, 4, when the train stops at a station, it's not necessary to limit passengers using lavatories.

Description

(1) Technical field [0001] The invention relates to a sewage discharge device in a train compartment toilet. (2) Background technology [0002] As we all know, in order to keep the cleanliness of the train station and prevent the waste from the compartment toilets from being discharged into the station, at present, before the train enters the station, the conductor locks the compartment toilet door, restricting the use of passengers, and waiting for the train to leave. After leaving the station, the conductor opened the toilet door again. This makes it extremely inconvenient for passengers and conductors who urgently use the toilet. Especially for the people who are using the toilet in the compartment when the train will enter the station, the use must be terminated immediately and come out from the toilet, making it very uncomfortable and extremely embarrassing. The difficulties caused by people who urgently need to use the toilet due to illness are even more self-evident...
