Embodiment of the utility model is illustrated below by accompanying drawings.

Fig. 1 is a schematic diagram of an embodiment of the utility model.

Fig. 2 is a structural principle diagram of the time-delay automatic switching valve in the embodiment of Fig. 1 .

Fig. 3 is the electrical control schematic diagram of the utility model.

In the embodiment of Fig. 1, two water storage cabinets 10 and 15 are placed respectively under the bathroom washbasin 3 and the kitchen sink 5 for washing vegetables. It is advisable that the bottoms of the two water storage tanks are connected by the pipe 15 laid along the kitchen to the bathroom floor so that the water in the two water storage tanks can communicate with each other. The water storage cabinet is connected to the drain outlet of the vegetable washing sink or washbasin and the sewage sewer pipe with PVC plastic pipe fittings, and a secondary valve is installed at the drain outlet of the vegetable washing sink and washbasin, whose function is similar to that commonly used in hydraulic and pneumatic transmission. The position three-way rotary valve is used as the drainage selector valve 4 for the user to choose whether to discharge the used waste water into the sewage sewer pipe or to discharge it into the water storage tank for subsequent use. The overflow port 17 provided on the top of the water storage tank is also connected with the sewage sewer pipe with PVC plastic pipe fittings. When the water in the water storage tank is full, it can overflow to the sewage sewer pipeline automatically, so that vegetables can be washed when the water in the water storage tank is full. Keep sink or washbasin drains clear. The water pump 9 installed under the water storage tank is mainly controlled by the pressure relay 7 connected in the pipeline. The water pump 9 pumps the water from the bottom of the water storage tank 10 to the toilet tank through the pipeline. Direction valve 8, accumulator 6 and time-delay automatic switching valve 2, when water pump 9 works, the pressure of water can make time-delay automatic switching valve 2 be in the connection state that makes the connection pipeline of water pump pipeline and flush toilet tank, simultaneously Make the connection pipeline between the tap water and the flush toilet water tank 1 be in a disconnected state, so that the water pump 9 can supply water to the flush toilet water tank 1 . When the water pump 9 supplies water to the toilet tank 1, as the water level in the toilet tank 1 increases, the opening of the float valve in the toilet tank decreases, and the pressure in the pipeline gradually increases, and the accumulator 6 connected to the pipeline simultaneously increases. Some pressure water has been accumulated. When the pressure rises to a certain level, the pressure relay 7 connected in the pipeline will act to cut off the power supply of the water pump 9 to stop working. At this time, due to the release of the check valve 8 and the accumulator 6 The combined effect of energy keeps a certain pressure in the pipeline so that the pressure switch 7 cannot be reset to turn on the power supply, and the water pump 9 is kept in a stopped working state. When the water level in the toilet water tank 1 was reduced after flushing the toilet, the pressure in the pipeline also decreased thereupon. At this moment, due to the time-delay effect of the delay automatic switching valve 2, the connection pipeline between the tap water pipeline and the toilet water tank 1 could not be closed immediately. Connect, the pressure relay 7 reconnects the power supply of the water pump 9 when the pressure in the pipeline drops to a certain degree, and the water pump 9 returns to the working state to supply water to the toilet water tank 1. A water level protection device controlled by a floating ball 11 is also installed in the water storage tank 10. It utilizes a float 11 that can float on the water surface as a water level sensing element. When the float floats up and down, it swings around a fulcrum. Magnet 12, when the water level in the cabinet lowers, float swings downwards, and the magnet 12 of its other end then swings upwards. There is also a magnet 13 with the same magnetism outside the water storage tank, and its other end is equipped with an electric contact. When the magnet 12 swings up and meets the magnet 13, because the magnets repel each other with the same sex, the magnet 13 is repelled downward so that the electric contact Disconnecting the circuit of the water pump 9 makes the water pump 9 unable to work even when the pressure relay 7 is connected, so as to protect the water pump 9 from idling in the case of water shortage. When the water pump 9 still cannot supply water to the toilet tank 1 after a period of time, the delay automatic switching valve 2 is switched to supply water from the tap water to the toilet tank 1 under the action of tap water pressure, and cut off the water supply path from the water pump 9 to the toilet tank 1 at the same time .

Fig. 2 is a structural principle diagram of the time-delay automatic switching valve in the embodiment of the utility model. Among the figure 1 is valve body, on valve body 1 there is the connection port that can be connected with tap water, water pump and flush toilet water tank respectively. The spool 2 is installed inside the valve body 1 and can slide axially. Normally, the spool 2 is located at the left end of the valve body 1 under the pressure of the spring 5 and the pipeline between the water pump and the toilet tank, and is in the passage from the water pump to the toilet tank. And cut off running water to the state of flush toilet water tank access. When the water pump is not supplying water, tap water can enter the sealed chamber A formed by the left end of the valve core 2 and the valve body 1 through the channel inside the valve body 1, and move to the right against the spring force of the spring 5 to squeeze the right end of the valve core 2 and the valve body 1. The liquid in the formed sealed cavity B, because the one-way valve 3 is in the closed state at this time, the liquid in the B cavity can only flow out through the damping hole 4, so the valve core 2 moves slowly, thus achieving the time delay when the water pump is not working. The purpose of connecting the pipeline passage between the tap water and the flush toilet water tank and cutting off the passage between the water pump and the flush toilet water tank at the same time. When the water pump resumes to work, the spool 2 is at the right end of the valve body 1 at this time, and the water pumped out of the water pump enters the chamber B through the passage inside the valve body 1 through the check valve 3, so that the spool 2 is quickly pushed to the left end and is at the right end again. Cut off the state of the water supply channel from the tap water to the flush toilet tank, and switch to the state of water supply from the water pump to the flush toilet tank.

Fig. 3 is the electrical control schematic diagram of the utility model. YJ is a pressure relay. When the pressure in the pipeline that the water pump supplies water to the toilet tank is lower than a certain value, YJ is in the on state, and when the pressure in the pipeline that the water pump supplies water to the toilet tank rises to a certain value, YJ is in the off state .
