Embodiment Construction

[0022] In general, the present invention provides a drain valve core and a drainage device using the drain valve core. The present invention is not limited to the type of specific drainage equipment, but as the most commonly used type, the drainage equipment of the present invention refers to those equipments that rely on the gravity of water to naturally drain water, such as sewers and floor drains. However, the invention is in fact also applicable to drainage installations which rely on additional powered equipment, such as pumps, to provide the flow of water. Moreover, the "drainage" mentioned in the present invention does not only refer to "draining water", but also refers to "transferring water from one container to another container", that is, as long as there is a scene of water flow, the present invention can be applied.

[0023] In addition, although it is referred to as "drainage" equipment in the present invention, the present invention is not limited to "water" in ...

Abstract

The invention discloses a drain valve element and a corresponding drain device. The drain valve element comprises shell (1) and seal (2); the upper portion of the shell (1) is barrel (11) having the two ends opened; the lower portion of the shell (1) is provided with at least three support arms (12) extended down from the lower end of the barrel (11). The lower ends of the support arms (12) are bent into the shell (1), the tail end of each support arm (12) is provided with slider (13). The lateral side of the seal is provided with slide channel (23) mating with the sliders. A permanent magnetis arranged in each of the seal and the sliders; mutual action of the permanent magnets enable the seal to tend to move up such that the upper portion of the seal can contact the inner side of the barrel under no action of external force to seal the drain valve element. The drain valve element can be automatically sealed, rarely causes dirt deposition, and has the advantages of smooth sliding, high water-entering speed, good durability and the like.

Description

technical field [0001] The invention belongs to the technical field of drainage equipment, and in particular relates to a drainage valve core used for drainage equipment such as a sink of a pool and a floor drain, and drainage equipment using the drainage valve core. Background technique [0002] The drain spool is the main functional component of various drainage equipment. In order to prevent backwater, deodorize, and insects, etc., the drain valve core is usually required to have a self-sealing function, so that the drain port can be closed when there is no water. There are many kinds of self-enclosed drain valve cores in the prior art, and if they are divided according to their principles, they can generally be divided into elastic return type and magnetic suction type. Among them, the magnetic suction drain valve core is more and more popular because of its simple structure and durability. However, the current magnetic suction type drain valve core also has its obviou...
