In the present invention, the electric quantity display and the adjustment circuit of the output voltage of the lithium battery pack are as shown in FIG. 8, and the specific working principle is as follows:

The switch S1 is closed, the current passes through the D2 diode (full speed state, the current flows through the D3 diode in the half speed state), and the battery pack voltage is divided by R1, R2, and R3 and then sent to U1 for detection. When U1 detects that the voltage across R3 is greater than or equal to At 2.5V, turn on test point 19 to Gnd, current flows through LED1 and R5, and illuminate green LED1, indicating that the battery pack is fully charged. At the same time, the voltage division of R8, R9, and R10 makes U2 due to the clamp of D1 diode. When the detection voltage is less than 2.5V, U2 cannot turn on test point 20 to Gnd, so that red LED 2 does not light up at the same time as green LED1;

When the battery pack voltage is reduced, after R1, R2, and R3 are divided and then U1 is less than 2.5V, U1 turns off the conduction test point 19 to Gnd, and the test point 19 position voltage is raised by the R4 pull-up to the battery pack voltage. Quite, the green LED1 turns off, the clamping effect of the diode D1 disappears, the battery pack voltage is divided by R8, R9, R10 and then sent to U2 detection. U2 detects that the voltage across R10 is greater than or equal to 2.5V, and the test point 20 is turned on. To Gnd, the current flows through the red LEDs 2 and R6, and the LED 2 is lit, indicating that the battery pack is not much charged;

When the battery pack voltage continues to decrease, the voltage is divided by R8, R9, and R10 and then sent to U2 to detect that the voltage across R10 is less than 2.5V, U2 is turned off to conduct test point 20 to Gnd, and the voltage at test point 20 is increased by R7 pull-up. Up to the voltage of the battery pack, the red LED2 is turned off, indicating that the battery pack is exhausted.

In the prior art, the pesticide is often sprayed in a water tank and sprayed on the crop.
