Embodiment 1
[0040] Please also refer to figure 1 and figure 2 , the present embodiment provides a water supply machine 100 , which includes a water pump 110 , a pressure sensor 120 , a controller 130 and a case 150 . The pressure sensor 120 is electrically connected to the controller 130 . The water pump 110 is provided with a non-contact switch 140 , and the controller 130 is electrically connected to the water pump 110 through the non-contact switch 140 . The pressure sensor 120 is used to sense the water supply pressure of the water pump 110 , and the controller 130 controls the on-off of the non-contact switch 140 according to the pressure sensed by the pressure sensor 120 .
[0041] As mentioned above, the water pump 110, the pressure sensor 120 and the controller 130 form a closed-loop control to control the water supply pressure of the water supply machine 100 at all times. The water pump 110 keeps working when the pressure does not reach the set value, and the water supply pres...
