AI Technical Summary

Technical Problem

In the existing technology, it is difficult to adjust the drinking chamber volume of ordinary water cups according to the different physical conditions of patients, which makes it impossible to accurately limit the amount of water consumed.

Method used

A water cup was designed that uses a liftable stopper to divide the inner cavity of the cup into a water storage chamber and a drinking chamber. By using a sealing component and a flow guide channel, combined with a telescopic hose and a column, the volume of the drinking chamber can be flexibly adjusted and automatically controlled.

Benefits of technology

It allows for adjusting the amount of water consumed according to the needs of different users, ensuring the accuracy and convenience of the drinking volume, and the volume can be easily observed through a transparent viewing window and scale.

Abstract

This utility model relates to the field of water cup technology, specifically to a water cup that facilitates control of drinking volume. It includes a cup body with a bottom cover at the bottom and a spout fixed through the top. A movable stopper plate is located inside the cup body, dividing the inner cavity into a lower water storage chamber and an upper drinking chamber. A flow channel is located at the center of the stopper plate, and a protruding tube is fixed at the top opening of the flow channel on the upper side of the stopper plate. A flexible retractable tube connects the top of the protruding tube to the bottom of the spout. A water outlet is located on the bottom side wall of the protruding tube. When the cup is inverted, water from the water storage chamber enters the drinking chamber through the flow channel and the water outlet. A sealing element is installed within the flow channel. When the cup is upright, the sealing element seals the bottom opening of the flow channel to prevent water from the drinking chamber from flowing back into the water storage chamber. When the cup is inverted, the sealing element releases the seal on the flow channel, allowing water from the water storage chamber to enter the drinking chamber.
