Elastic floor drain core with water seal

Abstract

The invention discloses an elastic floor drain core with a water seal. The elastic floor drain core mainly comprises an upturning edge, a seal ring, an upper cylindrical surface, an intermediate conical surface, a lower cylindrical surface, connecting passages, elastic closing passages and a water seal tank, wherein the quantity of the connecting passages is 1-6 and the quality of the elastic closing passages is the same as that of the connecting passages. The elastic floor drain core with the water seal can be made of silica gel, rubber or emulsion and also can be made of nylon or plastic. The water seal of the water seal tank is 5-90 mm in height, and ponding water in the water seal tank can more effectively prevent odor in a sewage conduit from emerging. The elastic floor drain core with the water seal can be mounted together with a novel floor drain for use, can also be instantly inserted into a conventional old floor drain for direct use, and is extensively applied to sanitary equipment of houses and residential buildings.

Description

technical field [0001] The invention relates to an elastic floor drain core with a water seal. It belongs to the plumbing fittings used in sanitary equipment. technical background [0002] Floor drains widely used in ground drainage in housing and residential building sanitary equipment often adopt a blister structure, which is composed of a water storage bowl, a drain pipe and a blister, which can effectively drain the accumulated water on the ground. Its shortcoming is that the height of the water seal liquid level formed by the water storage bowl, drain pipe and bubble cover of common floor drains is small, generally less than 10mm. When the water in the water storage bowl evaporates, the floor drain will be lost With the function of water seal, the odor under the floor drain will immediately come out of the floor drain, seriously polluting the surrounding air. [0003] In order to solve the problem of odor in the sewer pipe, a silicone floor drain core recently appeare...

Problems solved by technology

Its shortcoming is that the height of the water seal liquid level formed by the water storage bowl, drain pipe and bubble cover of common floor drains is small, generally less than 10mm. When the water in the water storage bowl evaporates, the floor drain will be lost Water seal function, the odor under the floor drain will immediately come out of the floor drain, seriously polluting the surrounding air

However, there is a small gap in the closed channel of the silicone floor drain core due to the use of the compression molding manufacturing process, and there is no water seal structure, so it cannot completely prevent the gas in the drain pipe below the floor drain from escaping upwards.

This kind of silica gel floor drain core also has only one closed channel, and the drainage flow rate is small, which cannot meet the drainage demand of larger flow rate when people bathe and do laundry.
