The invention relates to a push-pull type anti-reverse-spraying excrement collecting device. The device comprises a toilet stool, a large sewage tank, a cylinder body, a piston arranged in the cylinder body and sealing a cavity of the cylinder body, a driving mechanism capable of driving the piston to move in the axial direction of the cylinder body, and a one-way valve arranged in a sewage discharge pipe, wherein a sewage inlet pipe is connected to the lower end of the toilet stool; the sewage discharge pipe is connected with the large sewage tank; one end of the cylinder body is provided with a sewage outlet connected with the sewage discharge pipe, and the side wall of the cylinder body is provided with a sewage inlet connected with the sewage inlet pipe; and the piston closes the sewage inlet when the excrement collecting device does not work and moves towards the other end of the cylinder body firstly during sewage discharging so that negative pressure can be formed in the cavityclose to the sewage outlet and the sewage inlet pipe can be communicated to suck in sewage in the toilet stool, and then the piston moves towards one end of cylinder body so that positive pressure canbe formed in the cavity close to the sewage outlet and the one-way valve can be opened to enable the sewage in the cavity to enter the large sewage tank. The excrement collecting device is simple andreliable in structure and beneficial to saving production and use cost, and has a good anti-reverse-spraying effect.

    本发明涉及一种推拉式防反喷集便装置,包括便器和大污箱,所述便器下端连接有进污管,所述大污箱上连接有排污管,还包括缸体、设于缸体内并密封缸体空腔的活塞、可驱动活塞沿缸体轴向移动的驱动机构以及设于排污管中的单向阀;所述缸体的一端设有与排污管相连的排污口而侧壁上设有与进污管相连的进污口;所述活塞于集便装置不工作时封闭进污口而在排污时先向缸体的另一端运动以使靠近排污口的空腔形成负压并导通进污管管路以吸入便器中的污物而后向缸体的所述一端运动以使靠近排污口的空腔形成正压以将单向阀打开使空腔中的污物进入大污箱。该集便装置结构简单可靠,有利于节约生产和使用成本,并具有很好的防反喷效果。
