Intelligent auto-sensing pumping device

Abstract

The present creation includes at least a control circuit for performing the start, stop or test run modes of a motor, and a detection loop composed of two detection circuits, the two detection circuits connecting the control circuit to the motor and the guide of a waterproof case respectively. When there is no water or the water is pumped off, the pumping device remains in the stopped state due to disconnection of the detection loop. As the water level reaches the guide and enables conduction in the detection loop, the circuits of the motor would be actuated and work in accordance with the modes set by the control circuit.

1 . An intelligent auto-sensing pumping device comprising:
 a pump casing, provided for configuring a channel which varies the flow velocity and the flow capacity of liquid;   a motor, correspondingly arranged on the top of the pump casing and equipped with a rotating shaft correspondingly passing through the pump casing and extending into the interior thereof;   an impeller, enclosed in the pump casing and connected with the rotating shaft of the motor;   a waterproof case, correspondingly mounted on the exterior of the motor and a guide being disposed thereon;   a control circuit, disposed inside the waterproof case and provided with a converter unit to perform the operating mode of the motor; and   a detection loop, composed of two detection circuits, the two detection circuits connecting the control circuit to the motor and the guide respectively.   
   
   
       2 . The pumping device as described in  claim 1 , wherein the guide is an oil hole screw disposed at the waterproof case, and the oil hole screw is connected with the detection circuit by a copper pin. 
   
   
       3 . The pumping device as described in  claim 1 , wherein the guide is a sensor bar disposed at the waterproof case. 
   
   
       4 . The pumping device as described in  claim 1 , wherein the control circuit automatically determines whether the motor is no-load running and triggers the motor to turn off. 
   
   
       5 . The pumping device as described in  claim 1 , wherein the control circuit automatically determines whether the motor is overload running and triggers the motor to turn off. 
   
   
       6 . The pumping device as described in  claim 1 , wherein the control circuit can set up an intelligent restart function to restart the operation of the motor with automatic timing after the motor stops due to the occurrence of abnormal circumstances. 
   
   
       7 . The pumping device as described in  claim 1 , wherein the detection loop automatically triggers the motor to turn off under the condition of the guide covered by sludge. 
   
   
       8 . The pumping device as described in  claim 1 , wherein the control circuit automatically determines whether the motor is no-load or overload running and triggers the motor to turn off; and restarts the operation of the motor with automatic timing after the motor stops due to the occurrence of abnormal circumstances; and the detection loop automatically triggers the motor to turn off under the condition of the guide covered by sludge. 
   
   
       9 . The pumping device as described in  claim 1 , wherein the guide is disposed on the top of the waterproof case.
