The invention provides a miniature excrement collector which can be applied to an excrement collecting system of a train. The invention provides a piston pump structure which is used in cooperation with a bedpan and a flushing unit of a train excrement collecting system. The piston pump comprises two cylinder body sections, a first piston and a second piston are arranged in the cylinder body sections at the two ends respectively, and the two pistons are connected through a piston rod. A sewage inlet of the piston pump is connected to a sewage outlet of the excrement collector, a sewage outlet is connected with a sewage discharge pipe through a pipeline, and sewage is collected to a sewage collection box; a first valve gas source inlet is connected with a gas source, a first valve waste gas port is connected to a sewage inlet, and a first valve driving gas port is connected to a first piston pump gas hole; a valve II gas source inlet is connected with a gas source, a valve II driving gas port is connected to a second piston pump gas hole, and a valve II waste gas port is connected to a blow-off pipe; the controller controls opening and closing of the first valve and the second valve. The suction effect which can only be achieved through a large-capacity negative pressure space is achieved through piston movement, a vacuum structure is constructed, and the structure of the vacuum excrement collector can be simplified.
本发明提供一种微型集便器,可应用于列车集便系统。本发明提出一种活塞泵结构,配合列车集便系统便盆和冲水单元使用。活塞泵包括两个缸体段,两端缸体段内分别设置第一活塞和第二活塞,两个活塞经活塞杆连接;活塞泵的污水进口连接至集便器的排污口,污水出口经管路连接排污管,并收集至污物收集箱;阀一气源入口连接气源,阀一废气口连接至污水进口,阀一驱动气口连接至第一活塞泵气孔;阀二气源入口连接气源,阀二驱动气口连接至第二活塞泵气孔,阀二废气口连接至排污管;控制器控制阀一和阀二的开闭。本发明利用活塞运动达到了只有用大容量负压空间才能实现的抽吸效果,构造真空结构,可以简化真空集便器的结构。
