water quantity adjusting function: when the system is in normal operation, the water shortage indicator lamp is always on (the indicator lamp is arranged on the shell of the spraying equipment), and when the water shortage of the water tank is detected, the LED flashes; when the water shortage of the spray head is detected, the water pump is started to enable the water level to reach the detection position, the spray head liquid level probe works and then the liquid level detection power supply is turned on, the liquid level detection power supply is turned off at idle time, the adhesion of electrolyte on the surface of the electrode is reduced, and the service life of the electrode is prolonged.

the first state, currently illuminated, presses the key (i.e., spray key 14) and the system turns off the current illumination;

in the second state, when the key (i.e., spray key 14) is not currently illuminated, the system turns on the current illumination and resets the timer, first turning on the N-hour illumination function, turning off, and then turning on after an interval of N hours.
