Urinal water supply and drainage device

Abstract

The invention discloses a urinal water supply and drainage device. The upper end of a water supply pipe is arranged in a water supply and drainage tank. A pedal plate is arranged under the tank. An elastic reset component and a water supply valve are arranged under the pedal plate. The water supply valve is connected with the water supply pipe. The upper end of the water supply pipe is provided with a water supply pipe water outlet, and the pipe on the upper end is internally provided with a top plug. The top plug is connected with one end of a lever in the tank, and the other end of the lever is connected with a tank drainage port flip in a suspended manner. The tank drainage port flip is provided with a sealing portion. The tank is internally provided with a pull rod fulcrum which supports two ends of a pull rod to move up and down. When the pedal plate is stepped by a foot, the water supply valve is automatically opened to supply water to the tank, and meanwhile the top plug is jacked up, so as to drive the other end of the lever to press downward the tank drainage port flip, to seal and close off the tank water outlet. When the foot leaves the pedal plate, elastic force makes the water supply valve close, the top plug goes down to drive the other end of the pull rod to lift up the tank drainage port flip, and water in the tank is drained to a urinal to flush the urinal through the tank water outlet. The device prevents bacterial infection by contacting the buttons by a finger, and use is more sanitary.

Description

technical field [0001] The invention relates to a urinal, in particular to a water supply and drainage device used in the urinal. Background technique [0002] During the use of existing urinals, users generally need to press the button for drainage and flushing after use. However, because many people are afraid that the button is unhygienic, they do not press the button for drainage and flushing after use, forget to press the button, or Some users use their feet to step on the button after use, which makes the button more messy, which is not conducive to the use and flushing of the urinal and is not conducive to the normal maintenance of the service life of the urinal components; although some use automatic induction However, the urinal water supply and drainage device has the problems of complicated structure and high manufacturing success. Contents of the invention [0003] In order to solve the current situation of existing urinals such as inconvenient flushing with d...
