The invention provides a push-pull type excrement collector. The sewage inlet pipe is provided with an upper end opening, a sewage receiving port and a sewage discharge port, the upper end opening is communicated with the connecting pipe and connected to the bedpan, the sewage inlet pipe is communicated with the bedpan blow-off pipe, and an L-shaped structure is formed between the sewage inlet pipe and the bedpan blow-off pipe; the sewage discharge outlet is communicated with the sewage buffer area; the jet pipe is mounted at one end of the sewage receiving port; the opening direction of the jet pipe is consistent with that of the sewage discharge port; the jet pipe is connected with a gas source or a pressurized water source through a jet control valve, and a liquid jet source or a gas jet source is connected to the sewage inlet pipe. When the jet pipe sprays at a high speed, a vacuum area is formed in the sewage inlet pipe, and sewage discharge is promoted. The excrement collector further comprises an ejector, an ejector body is connected with the blow-off pipe, and a gap is formed between the ejector body and the blow-off pipe. An air inlet is formed in the ejector body, and the circumferential folding reducing pipe is connected to the ejector body. When high-speed compressed air is introduced into the ejector main body, the circumferential folding reducing pipe shrinks, a vacuum area is formed to prevent ejected air molecules from flowing back, and sewage discharge is promoted.
本发明提供一种推挽式集便器。进污管具有上端开口、承接污水口和污水排放口,上端开口与连接管连通并连接至便盆,进污管连通便盆排污管,二者之间形成L型结构;污水排放口与污水缓冲区连通;射流管安装在承接污水口一端,射流管开口方向与污水排放口一致;射流管通过射流控制阀与气源或增压水源相接,向进污管接入液体射流源或气体射流源。当射流管高速喷射时,进污管内形成真空区域,促进污水排放。集便器还包括喷射器,喷射器主体连接排污管,与排污管之间形成间隙。喷射器主体上设置有进气口,圆周折叠缩径管连接至喷射器主体。当向喷射器主体通入高速压空气,圆周折叠缩径管收缩,形成真空区域防止喷射出去的空气分子反流,促进污水排放。
