The invention discloses a double-acting flushing button switch, an excrement collecting system and an excrement collecting method. The double-acting flushing button switch comprises a button cap, thebutton cap is arranged in a shell, a shaft end fixing block is further fixedly arranged in the shell, a first spring is arranged between the shaft end fixing block and the button cap, and a proximityswitch is fixed to the end of the shaft end fixing block; the shaft end fixing block is connected with a manual valve assembly, the button cap and the outer shell can reciprocate in the same direction, the proximity switch is triggered when the button cap moves independently, and the manual valve assembly is opened when the button cap and the outer shell move at the same time.

Description

technical field [0001] The invention belongs to the technical field of sanitary toilet collection on trains, and in particular relates to a double-function flushing button switch, a stool collection system and a method. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, when passengers go to the toilet in the train toilet, they generally lightly press the flushing button to provide an electrical signal to the stool collection system, thereby triggering the flushing process and flushing the toilet. Yet the contriver finds, under the situation that there is no gas source and power supply on the train, the train toilet is unusable, and is in locked state. Now it is proposed that the train toilet toilet collection system can still be used normally without air source and power supply, but this button currently used cannot meet this requirement...
