Abstract: A universal non-convex press type drain, comprising: a drainpipe, having an upper stop section and a lower stop section; a pressing drain arranged inside the drainpipe and positioned by the lower stop section, the pressing drain has a stopper for stopping and draining water, the rise and fall of the stopper can be control by pressing; and a moveable strainer, the moveable strainer has a compression spring and has a pressing block below the moveable strainer; when the moveable strainer is not pressed, the compression spring makes the top edge of the moveable strainer aligned to the top edge of the drainpipe. So as to provide a non-convex press type drain which top edge is aligned to the installed surface and has the effect of preventing smell and insect.

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.
