Vacuum cup capable of cooling rapidly and being opened conveniently

Abstract

The invention provides a vacuum cup capable of cooling rapidly and being opened conveniently, and relates to the technical filed of vacuum cup. The vacuum cup capable of cooling rapidly and being opened conveniently comprises a cup body; a liner is fixedly installed in the cup body; an insulating layer is fixedly installed on the periphery of the liner in the cup body; a round hole is opened at the center of the bottom of the cup body; a cylindrical groove is opened under the round hole of the bottom of the cup body; and a rubber head is fixedly connected in the cylindrical groove by a spring.By adoption of the vacuum cup capable of cooling rapidly and being opened conveniently, part of the hot water in the liner flows into the cooling groove to accelerate cooling, so that the water can be drunk directly and other container is unnecessary; moreover, the hands can be warmed by the hot water in the cooling groove, so that the practicability of the vacuum cup is improved; when the cup cover is difficult to be opened due to the pressure difference between the inside and the outside, the internal space of the cup body can be reduced to increase the pressure in the cup body; and thus, the cup cover can be opened normally.

Description

technical field [0001] The invention relates to the technical field of thermos cups, in particular to a thermos cup that can quickly cool down and is easy to open. Background technique [0002] The thermos cup is a kind of cup that can make the temperature of the drinking water in the cup change slowly. It is generally a water container made of ceramics or stainless steel with a vacuum layer. There is a cover on the top, which is tightly sealed. Wait for the liquid to delay heat dissipation to achieve the purpose of heat preservation. With the development of science and technology, many different heat insulation materials have gradually appeared, making the types of thermos cups more and more. [0003] But no matter what kind of thermos cup, in order to achieve the effect of heat preservation, it needs to have high airtightness, but when hot water is poured into the thermos cup with high airtightness, as the water temperature drops slowly, the inside of the thermos cup The ...

AI Technical Summary

Problems solved by technology

[0003] But no matter what kind of thermos cup, in order to achieve the effect of heat preservation, it needs to have high airtightness, but when hot water is poured into the thermos cup with high airtightness, as the water temperature drops slowly, the inside of the thermos cup The pressure will gradually decrease, so under the action of atmospheric pressure, the cup lid becomes difficult to open, and the obvious defect of the traditional thermos cup is that the inside is full of high-temperature hot water, which cannot be drunk immediately and needs to be poured into other containers cooling, so it cannot meet the immediate needs of users
