Drainer with quick drainage and improved structure

Abstract

A drainer with quick drainage and improved structure has a drain body and a draining unit disposed in the drain body for stopping and draining water; the draining unit includes a base, a movable element, a rotatable element, a spring for ejection, an engaging ring element, an upper cover, and a rubber piece. The base has an inner tube in the middle, a periphery ring body, and a plurality of connecting ribs. The inner tube has a top end being higher than a top of the periphery ring body and an engaging space formed on the inner periphery thereof for the base to be disposed inside the drain body. The spring for ejection, the rotatable element, and the movable element are sequentially disposed in the inner tube and then the engaging ring element is mounted on the top end of the inner tube to form a movable unit for pressing with the upper cover mounted on the movable element and the rubber piece mounted on the periphery of the upper cover.

What is claimed is: 
     
         1 . A drainer with quick drainage and improved structure, comprising a drain body and a draining unit disposed in the drain body for stopping and draining water; the draining unit including a base, a movable element, a rotatable element, a spring for ejection, an engaging ring element, an upper cover, and a rubber piece;
 wherein the base has an inner tube in the middle, a periphery ring body, and a plurality of connecting ribs; the inner tube having a top end being higher than a top of the periphery ring body and having an engaging space formed on the inner periphery thereof for the base being disposed inside the drain body; the spring for ejection, the rotatable element, and the movable element being sequentially disposed in the inner tube; then the engaging ring element being mounted on the top end of the inner tube, forming a movable unit for pressing with the upper cover mounted on the movable element and the rubber piece mounted on the periphery of the upper cover.   
     
     
         2 . The drainer with quick drainage and improved structure as claimed in  claim 1 , wherein the connecting ribs are spirally arranged. 
     
     
         3 . The drainer with quick drainage and improved structure as claimed in  claim 2 , wherein each connecting rib further has a guiding concave arranged thereon. 
     
     
         4 . The drainer with quick drainage and improved structure as claimed in  claim 1 , wherein the drain body has inner screw threads arranged therein and the periphery ring body has outer screw threads arranged on the periphery thereof for engaging the base and the drain body, therefore disposing the base inside the drain body. 
     
     
         5 . The drainer with quick drainage and improved structure as claimed in  claim 1 , wherein the movable element has a protrusion end on the top thereof that has a threaded periphery for engaging inside screw threads arranged at the bottom periphery of the upper cover, therefore fixedly mounting the upper cover on the movable element. 
     
     
         6 . The drainer with quick drainage and improved structure as claimed in  claim 1 , wherein the rubber piece has a flange formed around the periphery thereof.
