A phase change thermostat cup

Abstract

The invention relates to a phase transition temperature adjusting cup, which comprises a cup body outer casing, a cup body inner casing and a top cover, and the composite phase transition material is filled between the inner casing and the outer casing. The composite phase transition material comprises phase transition material, a nucleating agent, heat conduction filling material and a thickening agent. The phase transition material is selected from one or more of sodium acetate trihydrate, sodium thiosulfate pentahydrate, twelve disodium hydrogen phosphate, sodium sulfate decahydrate and decahydrate. <{EN4}>The nucleating agent is selected from one or more of borax, sodium phosphate dibasic anhydrous, diatomaceous earth, silica, sodium silicate, eight water strontium hydroxide, hexahydrate chloride strontium. <{EN5}>The heat conduction filling material is selected from one or more of graphite, carbon nanotube, expanded graphite, carbon fiber, graphene, three-dimensional graphite foam, silicon carbide, copper powder. <{EN6}>The thickening agent is selected from one of polyacrylic acid emulsion or carboxymethylcellulose sodium. <{EN7}>Compared with existing temperature adjusting cups, the phase transition temperature adjusting cup of the present invention has the advantages of rapid cooling, simple structure convenient operation, 3-4 hours of comfort temperature zone, and not being restricted from external environment.

Description

technical field [0001] The invention relates to a phase change temperature regulating system, in particular to a phase change temperature regulating cup. Background technique [0002] With the development of society, people have higher and higher requirements for the taste and convenience of daily life. Among them, there are more and more functional requirements for drinking water cups. The cups with the function of adjusting water temperature are the most important among all functional cups. highlights. The specific requirements for temperature adjustment include: cooling with boiling water, cooling with normal temperature water, heating with cold water, etc. The current patents for temperature-regulating cups are as follows: Application No. CN201220702850 describes a cup with a temperature-raising and cooling-adjusting function. The temperature-raising adjustment adopts an electric heating device, and the temperature-lowering adjustment adopts the method of adding stirrin...

Problems solved by technology

[0003] The first type of thermos cup requires an external power supply, so the system is more complicated, and there are many limiting factors in the use process.

The second and third types of thermostat cups need to master the time and accurately judge whether the temperature of the liquid in the cup reaches the appropriate temperature range, so the accuracy of temperature control will be low.

The fourth type of thermos cup achieves the function of rapid cooling by adjusting the external heat exchange structure of the cup. This type of thermos cup has the same disadvantages as the second and third types, and you need to control it yourself and judge whether it reaches the appropriate temperature. , and the system design of this type is complex, and the requirements for the operator are slightly higher, and certain skills are required to bring out the excellent performance of this type of product. In addition, this type of thermostat cup can only realize one-way temperature adjustment, and cannot realize Liquid heating function

The fifth type of thermostat cup uses the characteristics of phase change materials to realize the temperature regulation function. This method is innovative, basically not limited by other factors, and easy to operate. Still lacking in speed
