Description

Technical Field

[0001] The utility model relates to the field of drains, in particular to a drain with a built-in overflow function. Background Art

[0002] The drainer is used to be installed on the drain hole of the wash basin. The wash basin can be used to store and release water through the drainer. In order to prevent excessive water from overflowing the wash basin, most of the existing wash basins are provided with an overflow port on the wash basin so as to discharge excess water. However, providing an overflow port will destroy the integrity of the wash basin, affect its appearance and easily hide dirt. In addition, some wash basins that do not have an overflow port for the sake of appearance do not have the overflow function.

[0003] As disclosed in application number: CN201820007824.5, a drain with an overflow function is provided with an overflow assembly on the drain, so that the drain has an overflow function without providing an overflow port on the wash basin, thereby overcoming the above problems. However, its overflow assembly is assembled through an overflow pipe, a drain pipe and a connector, and the structure is relatively complicated. In addition, the overflow pipe and the drain pipe are both corrugated pipes, which cannot independently maintain the connector above the top cover of the drain. When in use, the connector needs to be fixed to the outer wall of the wash basin to achieve the overflow function, which is inconvenient to install. In addition, the overflow pipe, the drain pipe and the connector have multiple connection points, which easily increase the risk of leakage. In addition, according to the attached drawings, the overflow main body is threadedly connected to the upper main body, and the direction of the overflow port is difficult to adjust using the threaded tightening structure, which is inconvenient to use. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a drain with a self-flowing water function.

[0005] In order to achieve the above content, the utility model adopts the following technical scheme: a water drain with built-in overflow function, including a water drain body, a bouncing core assembly and an overflow pipe, an overflow port and a drain port are arranged on one side of the water drain body, the overflow port is located above the drain port, the overflow pipe includes a hard pipe part and a soft pipe part, the port of the hard pipe part is installed on the overflow port, the port of the soft pipe part is installed on the drain port, the hard pipe part is composed of a horizontal hard pipe and a lifting hard pipe, one end of the lifting hard pipe is connected to the horizontal hard pipe, and the other end of the lifting hard pipe is located above the connection, a water storage port is arranged on the water drain body between the overflow port and the drain port, and a water storage gasket is arranged in the middle of the bouncing core assembly.
