[35] The solar water pump disclosed by the present invention mainly comprises a solar panel 1, a forward diode 3, a battery 4, a single chip microcomputer 9, a reed switch 11, a first switching element 10, and a water pump 14. The solar panel 1 is connected to the battery 4 through the forward diode 3 for charging. The solar panel 1 is connected to the water pump 14 through the first switching element 10 via the forward diode 3, and supplies sufficient power to the water pump 14 through the first switching element 10, and the battery 4 is connected to the water pump 14 through the first switching element 10, in the event of insufficient sunlight or nighttime.

When the water pump 14 is in the open (operating) state, the battery detecting voltage dividing device 7 detects that the battery 4 voltage drop reaches the set maintaining voltage 吋, and the single chip microcomputer 9 controls the water pump 14 to be turned off to stop the output, but the tripping device does not stop. The power supply required by the single chip microcomputer 9 is maintained to maintain the memory function, but when the voltage of the battery 14 drops below the minimum required voltage required by the battery, the hardware voltage detecting circuit 5 cuts off the total circuit switching element 6 and completely cuts off the output of the battery 4 to ensure that the battery 4 output is completely cut off. The battery will not be over-discharged. The voltage of the battery 4 exceeds the protection voltage. The voltage detection circuit 5 of the hardware will turn on the main circuit switching element 6 to turn on the power of the single-chip microcomputer 9. The single-chip microcomputer 9 is in the standby state, waiting for the customer to trigger the opening again.

[39] In this embodiment, the battery 4 is also connected to one end of a branch composed of the current limiting resistor 15 and the light emitting diode 13, and the other end of the branch passes through the first stage when the sunlight is insufficient or the night is supplied to the light emitting diode 13.
