Intelligent temperature control efficient heat preservation cup

Abstract

The invention provides an intelligent temperature control efficient heat preservation cup. The intelligent temperature control efficient heat preservation cup comprises a cup body, and is characterized in that the cup body comprises an inner cylinder wall, a heat conduction phase change layer, an aerogel thermal insulating layer and an outer cylinder wall, which are sequentially arranged from inside to outside. Due to the fact that the intelligent temperature control efficient heat preservation cup is made of high thermal conductivity phase change material and aerogel material, the intelligent temperature control efficient heat preservation cup has the remarkable advantages of being rapidly cooled to needed temperature, and capable of maintaining the needed temperature for a long time. The intelligent temperature control efficient heat preservation cup is wide in use, can replace a daily hollow thermal insulating cup and a daily vacuum thermal insulating cup in daily water drinking, and further can be used as a tea cup, a child milk drinking cup and the like.

Description

technical field [0001] The invention relates to a thermos cup, in particular to an intelligent temperature-controlled high-efficiency thermos cup. Background technique [0002] At present, common thermos cups on the market are generally sandwich-type vacuum or hollow thermos cups made of stainless steel, glass or pottery. Due to its good thermal insulation performance, the boiled water poured into the cup is in a high temperature state for a long time and cannot be drunk in time. , not conducive to drinking for a long time. In addition, for tea making (such as green tea at about 80°C), children's milk powder preparation (40 to 50°C), and milk drinking (about 40°C) thermos cups, due to the high temperature of boiling water, the useful ingredients in tea and milk powder will deteriorate. , lose nutritional value, and cannot drink quickly. [0003] Therefore, there is a need for a high-efficiency thermos cup that can quickly reduce boiling water to the required temperature i...

Problems solved by technology

[0006] Chinese patents CN92100602.0 and CN93201178.0 report a kind of rapid cooling heat preservation container, which is composed of phase change materials on the inner and outer walls of the container and the middle layer. The heat preservation container has widely used various phase change materials, but the inorganic salt Phase change materials like phase change materials have the problems of low thermal conductivity and poor cycle stability. Among them, phase change materials of fatty acids have the phenomenon of corroding the inner wall, and phase change materials of paraffin phase change materials have the problem of low thermal conductivity. In addition, the thermos cup is not well used Therefore, the practical application effect of the heat preservation container is limited; CN201110184586.8 reports a layered insulation cup, which is composed of conventional paraffin phase change materials and ordinary insulation layers, but the paraffin wax used The thermal conductivity is low, and the insulation effect of the insulation layer is average. Therefore, the layered insulation cup has a slow cooling efficiency of the water temperature in the cup (8 minutes to 70°C, 20 minutes to the drinking temperature of 50°C), the water temperature cannot be adjusted, and the insulation effect is limited. and other obvious practical problems; CN201420208307.6 reports a thermos cup with a nested phase change heat storage layer, which adopts a cylindrical phase change storage tank made of stainless steel with a closed interlayer side wall formed by a double wall. Heat layer, the preparation process of the airtight sandwich heat storage layer structure is extremely complicated, and there is a problem of deformation of the heat storage layer caused by the phase change material in the interlayer due to the alternating and repeated expansion and contraction during the long-term melting and solidification process, which in turn affects the inner tube wall. Close fit, resulting in a limited cooling effect due to the greatly reduced heat transfer efficiency of the hot water in the cup to the heat storage layer

In addition, the heat storage layer uses sodium acetate trihydrate, an inorganic hydrated salt, as a phase change material, which has the problems of low thermal conductivity (about 0.5W / mK), uncontrollable and poor cycle stability; CN201320414844.1 report A rapid cooling thermos cup is proposed, which is composed of a heat conduction layer (the inner wall of the thermos cup), an alloy metal phase change material, and a heat insulation layer. Due to the use of a metal phase change material with high thermal conductivity, the water temperature in the cup can be effectively cooled. However, the bismuth, gallium, indium, and tin alloy phase change materials have poor cycle stability, and have a strong corrosion effect on the inner wall and certain toxicity, so it is not easy to apply in large quantities

In addition, the thermos cup adopts traditional heat insulation methods such as vacuum glass, plastic or heat-insulating ceramics. Among them, the vacuum glass manufacturing process is complicated and there are large safety hazards, and plastic (0.2W / mK to 0.5W / mK) and ceramics (0.5W / mK to 5W / mK) has high thermal conductivity and poor heat insulation performance, so it is not suitable for long-term heat preservation

CN203953160U, CN200320116231.6 and other publicly reported phase-change thermos cups also have the above-mentioned similar failure to achieve good practical effects due to the limited functions of phase-change materials and heat-insulating layer materials.

[0007] The problems of the quick-cooling insulation cup (container) based on phase change material heat storage described in the above-mentioned published patents mainly include: (1) the thermal conductivity of the phase change material used is low; (2) the phase change of the phase change material The latent heat is limited; (3) the cycle stability of the phase change material is poor; (4) the thermal expansion rate of the phase change material is large; (5) the phase change material has certain toxicity; (6) the phase change material is expensive; (7) rapid cooling and heat preservation Cup insulation does not adopt heat insulation measures or the heat insulation effect is limited; (8) The long-term heat preservation performance is not good; (9) It is difficult to manufacture
