In this embodiment, the device flushes the toilet by combining sewage and clean water, which reduces the water consumption for single flushing, and at the same time, there will be some clean water for cleaning after flushing, ensuring the cleanliness of the squatting toilet . The design of the device is simple and reasonable in structure and easy to install; the whole device can be made of cheap PVC material, which is low in cost and easy to maintain; based on fluid mechanics and related mechanical principles, the process has no energy consumption and is economical. Moreover, the device will not change the structure of the original squatting toilet, can be popularized in a large range, and can be used in public toilets and family squatting toilets, and can achieve remarkable water-saving effects.

The specific embodiment: the device is composed of an auxiliary water tank, a discharge disc 19 and a water outlet valve 8 in three parts. The function of the auxiliary water tank is to collect the domestic waste water in the washbasin 1. The water inlet of the auxiliary water tank contains a simple filter system to filter the domestic waste water, and the water with less impurities will be collected into the auxiliary water tank. The upper part of the discharge disc 19 device is connected with the squatting pan water tank (main water tank) through a pipe, and the lower part is connected with the valve control device through a connecting rod. Through the openings on the discharge disc 19, the water flows out and mixes with the sewage to flush the toilet. When the amount of clean water on the discharge device is reduced to the theoretical calculation value, the sewage valve device connected through the connecting rod will be automatically closed, and the remaining clean water will flow out through the discharge device to flush the residual waste water in the pipeline and urinal, and act as an auxiliary water tank When the water intake is too much, excess water will flow into the water outlet from the overflow pipe 14. When the waste water in the auxiliary water tank is exhausted, resulting in the inability to provide waste water for flushing the toilet, the device uses the principle of toilet water tank water intake in a mobile way. The water inlet valve at the bottom of the auxiliary water tank can keep the water level in the auxiliary water tank at a certain height to avoid no water As a supplementary question, solid particles and other sundries may be mixed in the waste water flowing down from the sink 1, which needs to be simply filtered. The filter screen structure on the upper part of the auxiliary water tank is shown in the figure. When the waste water flows down from the sink, it flows through the fan-shaped filter screens on both sides to ensure that the waste water will not be filtered in time due to too fast flow. The filter screen is designed as a detachable structure, which is convenient for cleaning the filter screen. The main function of the three-way pipe 6 is to control the opening of the sewage valve to discharge the sewage for flushing the toilet by pressing down the discharge disc 19 while the main water tank is discharging water. A spring with an elastic constant of 200 N/m is built in the orifice of the disk 7, and is connected with the discharge disk 19. When the water in the main water tank flows down and hits the discharge disc 19, due to the large amount of water at the beginning, it will press down the discharge disc 19, and drive the No. 1 connecting rod 9 and No. 2 connecting rod 10 to move, thereby opening the water outlet valve 8, Simultaneously, the water on the discharge disc 19 flows down through the discharge holes on it, so that the sewage and clean water are mixed for flushing. When the water yield is reduced to its pressure not enough to depress the disk, the spring elasticity makes the disk 7 reset, the water outlet valve 8 is closed, and the remaining clean water continues to flow down from the discharge hole to clean the sewage in the pipeline and squatting pan. Considering that the connecting rod may deviate under repeated movement. Therefore it is designed as a connecting rod with a movable end and a limit setting. When the water in the main water tank makes the discharge disc 19 move down, it drives the connecting rod to move, and then drives the baffle, and finally opens the outlet valve 8. In order to ensure the normal sealing of the outlet valve 8, and the force of the connecting rod Make sure it opens to release waste water. The device uses the principle of engineering fluid mechanics. When the baffle is placed with a certain inclination angle, its pressure center is 1/3 away from the lower end. The connection between the baffle and the pipeline is designed to be below its pressure center, so as to ensure that the valve can achieve self-locking (guarantee its sealing) in the non-working state, and can be opened under the force of the connecting rod. In addition, the valve is designed with an inlaid structure around it and sealed with sealing strips, which can effectively prevent water leakage at the edge of the valve. Since the waste water from the auxiliary water tank must pass through the pipeline during use, it is very easy to form impurities at the bottom under long-term work, and the pipeline is closed. It is very difficult to clean up, and it will greatly affect the installation work after a long period of time. Therefore, the pipeline is inclined at a certain angle during installation, so that impurities flow to the lower edge of the pipeline with the water. Special treatment shall be given to the pipes connected to the outlet valve. As shown in the figure, the bottom edge of the rectangular valve forms a curved surface with the surrounding pipes. After the valve is opened, the impurities will be washed away with the water flow, thereby solving the problem of impurities accumulation. The water inlet pipe at the upper end of the auxiliary water tank is connected to the bottom of the sink, and the water in sink 1 flows through the auxiliary water tank. The simple filter screen stored in the auxiliary water tank is ready for use. The filter screen is used to filter large particles of impurities to avoid clogging the pipeline, and it is set as a detachable structure for easy disassembly and cleaning. The device ingeniously transfers the water storage principle of the main water tank. When the sewage content in the water tank is too little, the water inlet valve 16 will automatically replenish clean water; Auxiliary water tank water outlet is connected with discharge disk 19 and the sewage valve device in the three-way pipeline by pipeline, and the upper end of the discharge mechanism connects squatting pan water tank, and the left end is connected with auxiliary water tank water outlet, and the right end is used as squatting pan drainage. When the main water tank comes out, the water flow presses down the discharge disc 19 according to the momentum, and the first connecting rod 9 and the second connecting rod 10 connect the water outlet valve 8 to open, so that the sewage flows out, and at the same time, the clean water passes through the discharge valve 19 on the discharge disc 19. The outflow from the small hole is mixed with the sewage to flush the toilet. When the remaining clean water is about 400ml, due to the elastic force of the spring between the disc 7 and the connecting rod, the disc 7 is bounced up, the sewage valve is closed, and the remaining clean water flows down to achieve the purpose of cleaning the pipeline and squatting toilet.

The above-mentioned technical solutions only reflect the preferred technical solutions of the technical solutions of the present invention, and some changes that those skilled in the art may make to certain parts reflect the principles of the present invention and fall within the protection scope of the present invention.
