Small ozone gas-water mixing pump

Abstract

The present invention provides a small ozone gas-water mixing pump. The rotation of the leaves drives water to produce intense turbulence vortex, and the bubbles in the water are torn up producing more and smaller bubbles, so that the gas-water contacting area is enlarged, and the ozone is efficiently dissolved into water. The magnetic force between the permanent magnet A on impeller and the permanent magnet B on motor enables the motor driving the impeller without using shaft, so as to avoid sealing problems of the pump driving shaft. The present invention is simple in structure, low cost, safe, stable, and has high ozone dissolving efficiency, so that it is especially applicable to the household appliances, such as dish washers and washing machines, etc.

1 . A ozone-water mixing pump having the motor output power less than 50 W, comprising a pump casing, an impeller, and a motor, wherein a permanent magnet A ( 4 ) is mounted on the impeller, outside of the pump casing, at a place corresponding to the permanent magnet A ( 4 ), a permanent magnet B ( 5 ) is mounted on a device connected with the rotor of the motor. 
   
   
       2 . The ozone-water mixing pump, as recited in  claim 1 , wherein the mixing pump is vortex type. 
   
   
       3 . The ozone-water mixing pump, as recited in  claim 1 , wherein N-S polar direction of the permanent magnets A and B is the axial direction of the motor and the impeller. 
   
   
       4 . The ozone-water mixing pump, as recited in  claim 1 , wherein the adjacent permanent magnets A have opposite magnetic polarity. 
   
   
       5 . The ozone-water mixing pump, as recited in  claim 1 , wherein the permanent magnets A and B are made of Nd—Fe—B. 
   
   
       6 . The ozone-water mixing pump, as recited in  claim 1 , wherein the pump casing is made of plastic. 
   
   
       7 . The ozone-water mixing pump, as recited in  claim 1 , wherein the permanent A ( 4 ) is imbedded in the impeller.
