In this embodiment, the external power 7 is the mains power. The transformer unit 5 is used to convert the mains power to AC24V and provide it to the control board 41. The control board 41 then controls the electromagnetic contactor 42 to operate with AC24V. The control board 41 converts AC24V to DC24V to control the warning light group 61 to display a light signal and control the buzzer 62 to emit a warning sound.

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

The following describes four abnormal states.
