Phase change heat accumulation fast cooling temperature control cup

Abstract

The invention relates to a phase change heat accumulation fast cooling temperature control cup, which comprises a cup body, wherein the cup body is provided with a cup cover (1), an inner liner (3) and an outer liner (2), wherein a vacuum cavity (4) is formed between the inner liner (3) and the outer liner (2); the temperature control cup also comprises a plurality of groups of phase change heat conduction structures and a control switch; the plurality of groups of phase change heat conduction structures are uniformly arranged in the vacuum cavity, and comprise arc-shaped heat conduction cases(5), phase change materials (6), heat conduction sheets (14) and position limiting sheets (15); the control switch is arranged at the bottom of the cup body, and comprises inner and outer magnet groups in paired configuration and a regulating ring (11); in a heat radiation state, the regulating ring (11) rotates, so that magnetic poles of the inner and outer magnets become different to mutually attract; the inner magnet (16) drives the heat conduction sheet (14) to be in contact with the outer liner (2) for heat radiation; when the temperature in the cup is too high, the arc-shaped heat conduction case (5) is heated to expand and is in contact with the outer liner (2) for transmitting the heat out of the cup; in the heat insulation state, the regulating ring (11) rotates, so that the magnetic poles of the inner and outer magnets become identical to repellent mutually; the inner magnet (16) drives the heat conduction sheet (14) to be separated from the outer liner (2) for heat insulation. The cup can be used for fast cooling, and can also maintain the temperature at the value suitable for drinking for a long time.

Description

technical field [0001] The invention relates to a temperature-controlled cup, in particular to a temperature-controlled cup with rapid cooling and controllable thermal insulation. Background technique [0002] The thermos cups currently on the market are generally water containers made of ceramics or stainless steel plus a vacuum layer. There is a cover on the top and the seal is tight. The purpose is to minimize heat loss and achieve heat preservation. To reduce heat loss, it is necessary to consider the three basic ways of heat transfer, namely heat conduction, heat convection and heat radiation. [0003] (1) Heat conduction: When there is no relative displacement between parts of an object or direct contact between different objects, the heat transfer generated by the thermal motion of molecules, atoms, free electrons and other microscopic particles of the substance is called heat conduction (heat conduction), Theoretically speaking, heat conduction can be carried out in...

AI Technical Summary

Problems solved by technology

[0010] In daily life, after pouring hot water into the thermos cup, due to the heat preservation effect of the thermos cup, it cannot quickly drop to a temperature suitable for drinking, and when it is cooled enough to drink, it cannot be kept at this temperature for a long time.

In addition, the existing quick-cooling thermos cups on the market only have a better quick-cooling effect for the first cup of hot water, and the quick-cooling effect cannot be achieved when the next cup of hot water is poured in immediately.
