Smart pump

Abstract

A smart water pump includes a housing ( 5 ). An outlet box cover ( 13 ) is arranged on the top of the housing ( 5 ), and a power plug ( 1 ) is arranged at an upper part of the outlet box cover ( 13 ). A circuit board ( 2 ) is arranged within the housing ( 5 ); a rotor ( 4 ) and a stator ( 6 ) are arranged under the circuit board ( 2 ). A motor front cover ( 7 ) is arranged at a lower part of the housing ( 5 ); a turbine housing ( 8 ) is arranged under the motor front cover ( 7 ); an impeller ( 10 ) is arranged within the turbine housing ( 8 ), and the impeller ( 10 ) shares a rotary shaft ( 3 ) with the rotor ( 4 ). A water outflow pipe ( 14 ) is arranged on one side of the housing ( 5 ), and a water level sensor ( 12 ) is arranged on the other side of the housing ( 5 ). The water level sensor ( 12 ) includes a sensor box ( 15 ). A sensing probe is arranged on the sensor box ( 15 ), and includes a high water level probe ( 16 ), a low water level probe ( 17 ), and a ground probe ( 18 ). The high water level probe ( 16 ) is shorter than the low water level probe ( 17 ), and the low water level probe ( 17 ) is shorter than the ground probe ( 18 ). Water pumps employing the water level sensor ( 12 ) can control the rotation of the water pump on the basis of the water level, ameliorating a common scenario with existing water pumps in which the water pump does not work when water is available and works when water is unavailable.

What is claimed is: 
     
         1 . A smart water pump, comprising a housing ( 5 ), wherein an outlet box cover ( 13 ) is arranged on the top of the housing ( 5 ), and a power plug ( 1 ) is arranged at an upper part of the outlet box cover ( 13 ); a circuit board ( 2 ) is arranged within the housing ( 5 ); a rotor ( 4 ) and a stator ( 6 ) are arranged under the circuit board ( 2 ); a motor front cover ( 7 ) is arranged at a lower part of the housing ( 5 ); a turbine housing ( 8 ) is arranged under the motor front cover ( 7 ); an impeller ( 10 ) is arranged within the turbine housing ( 8 ), and the impeller ( 10 ) shares a rotary shaft ( 3 ) with the rotor ( 4 ); a water outflow pipe ( 14 ) is arranged on one side of the housing ( 5 ), and a water level sensor ( 12 ) is arranged on the other side of the housing ( 5 ). 
     
     
         2 . The smart water pump according to  claim 1 , wherein the water level sensor ( 12 ) comprises a sensor box ( 15 ), and a sensing probe is arranged on the sensor box ( 15 ). 
     
     
         3 . The smart water pump according to  claim 1 , wherein the sensing probe comprises a high water level probe ( 16 ), a low water level probe ( 17 ), and a ground probe ( 18 ); the high water level probe ( 16 ) is shorter than the low water level probe ( 17 ), and the low water level probe ( 17 ) is shorter than the ground probe ( 18 ). 
     
     
         4 . The smart water pump according to  claim 1 , wherein a strainer ( 9 ) is arranged under the turbine housing ( 8 ), and a small strainer ( 11 ) is arranged at a position where the water level sensor ( 12 ) is installed in the housing ( 5 ).
