Drain plug assembly

Abstract

A drain plug assembly includes an operation unit including a button and a cable is connected between the button and a plug unit which is located in a drain hole of a drain pipe. The cable that is located close to the button is received in a part of a sink and the cable that is located close to the plug unit is received in the drain pipe. A positioning unit is located between the button and the cable so as to control the button at different positions and to drive the cable to move the plug unit. A hose is mounted to the cable. When pushing the button, the cable is moved upward to push the plug upward for draining purpose. The cable is well protected and does not expose so that the cable is not tangled, pulled or damaged by foreign objects.

1 . A drain plug assembly comprising:
 an operation unit including a button and a cable which has one end connected to an underside of the button and the other end of the cable connected to a plug unit which is located in a drain hole of a drain pipe, the first end of the cable that is located close to the button is received in a part of a sink and the second end of the cable that is located close to the plug unit is received in the drain pipe;   a positioning unit located between the button and the cable so as to control the button at different positions and to drive the cable to move the plug unit, and   a hose mounted to the cable.   
   
   
       2 . The drain plug assembly as claimed in  claim 1 , wherein the plug unit includes a central tube and a plurality of radial plates extend radially from the central tube and are connected to a collar, a protrusion extends from a first end of the central tube and a connector is connected to a second end of the central tube, a plug is connected to the protrusion. 
   
   
       3 . The drain plug assembly as claimed in  claim 2 , wherein the second end of the cable extends through the connector and is connected to the protrusion in the central tube. 
   
   
       4 . The drain plug assembly as claimed in  claim 1 , wherein a seal member is connected to the hose and located between the sink and the drain pipe. 
   
   
       5 . The drain plug assembly as claimed in  claim 1 , wherein the positioning unit includes a cylindrical case and a tube extends from an end of the cylindrical case, a polygonal passage is defined through the tube and a polygonal rod is movably inserted into the polygonal passage, an end of the polygonal rod is connected to the button and the other end of the polygonal rod is connected with a rotational member, a first spring is mounted to the polygonal rod, an inner piece is inserted into the other end of the cylindrical case and includes a plurality of spikes which are located in the cylindrical case. 
   
   
       6 . The drain plug assembly as claimed in  claim 5 , wherein the first end of the cable extends through the inner piece and is connected to a push rod located at a center of the spikes, the push rod is connected to the rotational member.
