In the embodiment, the external power 7 is a commercial power, and the transformer unit 5 is used to convert the utility power into AC24V and is provided to the control board 41. The control board 41 then controls the electromagnetic contactor 42 to operate by AC24V. The control board 41 converts the AC24V to DC24V to control the warning light group 61 to display the light number and to control the buzzer 62 to emit a warning sound.

In use, when the switch signal corresponds to an abnormal state in which the bucket cover is not covered by the filter bucket, the pressure signal is an abnormal state corresponding to the pressure of the fluid being less than or greater than a preset pressure range, or the flow rate When the signal is an abnormal state corresponding to the flow of the fluid being less than or greater than a predetermined flow range, the control panel controls the buzzer 62 to emit a warning tone, and controls the warning light group 61 to display the light signal.

The following four abnormal states are described. When the switch signal corresponds to an abnormal state in which the bucket cover is not covered by the filter bucket, the control panel 41 controls the electromagnetic contactor 42 to electrically disconnect the external power 7 . The motor 3, while the motor 3 is not operating, controls the panel 41 and controls the red light to illuminate.

When the pressure signal is an abnormal state corresponding to the pressure of the fluid being less than the preset pressure range, the control board 41 controls the electromagnetic contactor 42 to electrically connect the external power 7 to the motor 3, so that the motor 3 Without functioning, the control panel 41 controls and causes the blue light 613 and the red light 611 to illuminate.
