Water cup closed automatically in case of falling down

Abstract

The invention provides a water cup in case of falling down. The water cup comprises a cup cover and a cup body, wherein the cup cover is connected with the cup body through a hinge pin; an embedded iron block is arranged in the cup cover; an inductance coil and an iron core are arranged inside the side wall of the cup body; the iron core is positioned in the inductance coil; one end of the inductance coil is connected with one pole of a battery through a power switch, and the other end of the inductance coil is connected with the other pole of the battery through a liquid closed switch; the liquid closed switch comprises an enclosed container and conducting liquid filled into the enclosed container; the bottom surface and the top surface of the enclosed container are made of a conducting material; the side face of the enclosed container is made of an insulating material. The liquid closed switch is similar to the water-holding cup body in structure. When the water cup falls down accidentally, the liquid closed switch is switched on, the inductance coil and the iron core undergo electromagnetic induction, attraction is generated on the embedded iron block, and the cup cover is closed, thereby effectively solving the problem of water leakage in case of accidental falling down of the water cup.

Description

technical field [0001] The invention belongs to the field of daily necessities, in particular to a water cup that can be automatically closed when the water cup is accidentally toppled over. Background technique [0002] As a necessity in daily life, water cups have many shapes and functions. In terms of function, the water cup has the functions of heat preservation, leak prevention, balance or adjustment of weak alkalinity, negative potential and oxygen content of water. As far as the leak-proof function is concerned, the leak-proof function of the water cup in the past is mainly realized by adding a rubber sealing ring. Weakness: it only supports the leak-proof when the user has completely closed the cup lid. Water glasses with straws are also partially leak-proof, but their weaknesses are also prominent: the spout is small, and when pouring, a small amount of water will still leak through the straw that is not tightly closed. In addition, there is a water cup that has a...
