Detailed ways

The specific content of the utility model is described in detail in conjunction with the accompanying drawings. An intelligent water level monitoring and control device includes a water inlet pipe 1, a straight-through water tap 2 and a solenoid valve 3 connected between the water inlet pipe 1 and the straight-through water tap 2. The solenoid valve 3 is composed of 220V power supply, the water outlet of the straight-through faucet 2 is provided with an ultrasonic transmitting and receiving module 4, and one side of the straight-through faucet 2 is provided with a main control circuit board 5, and the main control circuit board 5 is provided with a ready indicator light 6 and a water outlet indication Lamp 7, display screen 8, buzzer and control button 9, the interior of main control circuit board 5 is provided with control circuit and power supply, and this control circuit comprises single-chip microcomputer 15 and the reset circuit 10 that links to each other with single-chip microcomputer 15 pins, alarm circuit 11 , a relay circuit 12, an indicator light circuit 13, a crystal oscillator circuit 14, an ultrasonic transmitting and receiving module circuit 16, a button circuit 17 and a display circuit 18.

As shown in Figure 1, first set the water outlet control button on the main control circuit board, set the water outlet level, and then the ultrasonic transmitting and receiving module detects the change of the water level in the container or cup. Initially, when the container is placed directly under the faucet, the ultrasonic transmitting and receiving module detects When the distance changes, the signal is sent to the single-chip microcomputer on the main control circuit board, and the single-chip microcomputer processes and responds to judge whether there is water. If the water outlet condition is met, the main control circuit board controls the solenoid valve to energize the water outlet, and when the change of the liquid level distance meets the set value of the water outlet, the main control circuit board turns off the solenoid valve to stop the water outlet.
