Pump for foot bath

Abstract

A pump for a foot bath includes a lower cover, an upper cover, a rotation disk, and a power motor. The lower cover has an inside formed with a mounting hole. The upper cover has an inside formed with a chamber. The rotation disk is rotatably mounted between the upper cover and the lower cover. The power motor has a lower portion provided with a rotation shaft secured to the rotation disk so that the rotation disk is rotated in concert with the rotation shaft synchronously. Thus, the lower portion of the power motor is extended into the inside of the upper cover and encompassed by the upper cover, thereby greatly reducing the sound produced during rotation of the power motor.

1 . A pump, comprising a lower cover, an upper cover, a rotation disk, and a power motor, wherein: 
 the lower cover has an inside formed with a mounting hole;    the upper cover is mounted on the lower cover and has an inside formed with a chamber communicating with the inside of the lower cover;    the rotation disk is rotatably mounted between the upper cover and the lower cover;    the power motor is mounted on the upper cover and has a lower portion provided with a rotation shaft extended into the upper cover and secured to the rotation disk so that the rotation disk is rotated in concert with the rotation shaft of the power motor synchronously.    
     
     
         2 . The pump in accordance with  claim 1 , wherein the lower cover has a plurality of mounting plates mounted in the mounting hole and a plurality of flow passages defined between the mounting plates and communicating with the inside of the lower cover.  
     
     
         3 . The pump in accordance with  claim 1 , wherein the lower cover  1  has a side formed with a lower semi-circular hole communicating with the inside of the lower cover, and the upper cover has a side formed with an upper semi-circular hole communicating with the chamber and juxtaposed to the lower semi-circular hole of the lower cover to form a circular flow channel.  
     
     
         4 . The pump in accordance with  claim 1 , wherein the lower cover  1  as a periphery formed with a plurality of fixing ears, and the upper cover has a periphery formed with a plurality of fixing ears secured to the fixing ears of the lower cover by a plurality of locking screws so that the upper cover is secured to the lower cover.  
     
     
         5 . The pump in accordance with  claim 1 , wherein the upper cover has a protruding post extended into the chamber.  
     
     
         6 . The pump in accordance with  claim 5 , wherein the protruding post of the upper cover has an inside formed with a mounting bore, and the lower portion of the power motor has a protruding mounting portion mounted in the mounting bore of the protruding post of the upper cover.  
     
     
         7 . The pump in accordance with  claim 6 , wherein the protruding post of the upper cover has a periphery formed with a plurality of elongated slots surrounding the mounting bore.  
     
     
         8 . The pump in accordance with  claim 1 , wherein the upper cover has a bottom having a periphery formed with an elongated protruding strips inserted into a top of the lower cover to provide an air-tight effect between the upper cover and the lower cover.  
     
     
         9 . The pump in accordance with  claim 1 , wherein the rotation disk has a substantially inverted hill shape.  
     
     
         10 . The pump in accordance with  claim 1 , wherein the rotation disk has a lower portion formed with a protruding block received in the mounting hole of the lower cover.  
     
     
         11 . The pump in accordance with  claim 1 , wherein the rotation disk has a periphery provided with a plurality of longer blades and a plurality of shorter blades arranged in a staggered manner.  
     
     
         12 . The pump in accordance with  claim 1 , wherein the lower portion of the power motor is extended into the inside of the upper cover and encompassed by the upper cover.  
     
     
         13 . The pump in accordance with  claim 6 , wherein the rotation shaft of the power motor is extended through the mounting bore of the protruding post of the upper cover.  
     
     
         14 . The pump in accordance with  claim 1 , wherein the lower cover  1  has a side formed with two parallel lower semi-circular holes communicating with the inside of the lower cover, and the upper cover has a side formed with two parallel upper semi-circular holes communicating with the chamber and juxtaposed to the lower semi-circular holes of the lower cover to form two circular flow channels.
