Detailed Description

As shown in fig. 1, a reclaimed water inlet pipe 2, a tap water inlet pipe 3 and a water outlet pipe 4 are installed on the side surface of a water storage tank 1, a normally open type electromagnetic valve 5, a water flow sensor 6, a one-way valve 7, a relay 8, a filter 9 and a water level sensor 10 are installed in the water storage tank 1, the water level sensor 10 is positioned at the lower part of the water storage tank 1, and a water pump 11 is installed at the bottom of the water storage tank 1. The filter 9 is provided with a filter screen, and the reclaimed water inlet pipe 2 is communicated with the filter 9. The tap water inlet pipe 3 is communicated with a water inlet of a normally open type electromagnetic valve 5, a water outlet of the normally open type electromagnetic valve 5 is communicated with a water inlet of a water flow sensor 6 and a water outlet of a one-way valve 7, a water outlet pipe 4 is communicated with a water outlet of the water flow sensor 6, a water outlet of a water pump 11 is communicated with a water inlet of the one-way valve 7, and a water inlet of the water pump 11 is positioned at the bottom of the water storage tank 1. An overflow pipe 12 is arranged at the upper part of the water storage tank 1 and is communicated with the outside of the water storage tank 1, and is used for draining water when the waste water in the water storage tank 1 is excessive.

Fig. 2 is a circuit diagram of the present embodiment, the power supply is a 12V dc power supply, the water level sensor 10 and the water flow sensor 6 are connected by a wire to form a series circuit, one end of the series circuit is connected to the negative electrode of the power supply, the other end is connected to the input loop of the relay 8, and the relay 8 is connected to the power supply.
