A thermos cup capable of rapid cooling and easy to open

Abstract

The invention provides a thermos cup capable of rapidly cooling down and being easy to open, and relates to the technical field of thermos cups. The thermos cup capable of quickly cooling down and being easy to open includes a cup body, an inner liner is fixedly installed inside the cup body, an insulation layer is fixedly installed on the periphery of the inner liner in the cup body, and a center of the bottom of the cup body is opened. A circular hole, a cylindrical groove is opened below the circular hole at the bottom of the cup, and a rubber head is fixedly connected to the inside of the cylindrical groove through a spring. The thermos cup that can quickly cool down and is easy to open can make part of the hot water in the inner tank flow into the cooling tank to accelerate cooling, so that it can be drunk directly when drinking is needed, and does not need to use other containers, while the hot water in the cooling tank It can also warm hands, thereby improving the practicability of the thermos cup. When the lid is difficult to open due to the pressure difference between the inside and outside, the inner space of the cup body can be reduced to increase the pressure in the cup body, which is helpful for the normal operation of the cup lid. Open.

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 ...

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
