Structural improvement of a water drainer in a cistern

Abstract

A structural improvement of a water drainer in a cistern is disclosed. The water drainer has a draining part which has a moving module inside. The moving module has a central hole, in addition, has an upper float-ball and a lower float-ball at inner space to match the upper slot and the lower slot which both are set up on the draining part. Furthermore, an outer convex ring set on a rubber module is fixed into the draining hole on the bottom of the cistern, and an outer convex ring on the cylinder at the lower portion of the draining part is inserted into the hole of the rubber module, meanwhile the latch of the cylinder is hooked onto the bottom of the rubber module to make the water drainer be fixed. With the structural improvement, a purpose of two-stage water draining can be achieved.

1 . A structural improvement of a water drainer in a cistern, comprising:
 a moving module which has a central hole, has a flush valve at lower portion, and has an upper float-ball and a lower float-ball at inner space;   a draining part which is installed at outside of the moving module, has an upper slot and a lower slot, also has an outside-tapered cylinder at lower portion; the cylinder has at least one or more than one of outer convex ring and latch on the surface, and a base on it; and   a rubber module which is installed at outside of the cylinder of the draining part, has flanges separately at top and bottom, and has an outer convex ring at middle; the hole of rubber module is hollow shaped with internal taper.   
     
     
         2 . The structural improvement of a water drainer in a cistern as defined in  claim 1 , wherein the inner space of the cylinder of the draining part and the base are outlet holes which has a flange on it, the flange is conjugated with a flush valve. 
     
     
         3 . The structural improvement of a water drainer in a cistern as defined in  claim 1 , wherein one end of the upper float-ball and the lower float-ball of the moving module has a plate separately, each plate has an engaging-surface on it. 
     
     
         4 . The structural improvement of a water drainer in a cistern as defined in  claim 1 , wherein the outer convex ring of the rubber module is conjugated and fixed into the draining hole on the bottom of the cistern; the outer convex ring of the cylinder at lower portion of the draining part is clicked into the hole of the rubber module, meanwhile the latch of the cylinder is hooked with the bottom of the rubber module to make the water drainer be fixed.
