[0049] Furthermore, when the detection device 2 does not detect that there is AC power input to the AC power supply device 1, the detection device 2 will feed back a no AC voltage signal to the control board 7, and transmit the DC power to the main switch 3 through the battery 6. The main switch 3 turns on the DC power, and then adjusts the voltage output by the battery 6 through the control board 7, so that the voltage transmitted to the DC motor pump 8 is stable, thereby driving the DC motor pump 8 to work.

[0066] Specifically, Figure 2 As shown, firstly, an AC power supply device 1 is used to provide a preset AC power supply, and then a detection device 2 is used to determine whether the AC power supply device 1 has an AC power input.

[0067] Furthermore, when the detection device 2 determines that the AC power supply device 1 has AC power input, the main switch 3 is used to connect the control board 7, the control board 7 adjusts the AC power to a stable state, and turns on the AC motor pump 4 to drive the high-pressure cleaning machine to work; when the detection device 2 determines that the AC power supply device 1 has no AC power input, the detection device 2 will feedback the no AC voltage signal to the control board 7, drive the main switch 3 to turn on the control board 7 through the battery 6, and the control board 7 adjusts the voltage transmitted by the battery 6 to a stable state, and turns on the DC motor pump 8 with the stable voltage to drive the high-pressure cleaning machine to work.
