Description

Heat preservation device capable of controlling temperature in different areas
Technical Field
The invention relates to a heat preservation device, in particular to a heat preservation device capable of controlling temperature in different regions.
Background
The heat preservation devices such as the heat preservation cup, the heat preservation lunch box and the like are daily necessities widely used in daily life, the heat preservation device with excellent working performance can slow down and even block heat transfer between liquid in the device and the outside, the effect of keeping the temperature of the liquid in the device for a longer time is achieved, and great convenience is provided for people to preserve, drink or eat liquid and food with different temperatures. The double-layer vacuum cup mainly utilizes a gap layer existing in a double-layer cup shell as a heat insulation material for delaying heat dissipation, the vacuum cup is based on the double-layer vacuum cup, air between the gap layers is pumped out to form vacuum, liquid in the cup is delayed to dissipate heat through the vacuum heat insulation layer, the purpose of heat preservation is achieved, and the vacuum cup is a high-grade vacuum cup with better heat preservation effect. The vacuum thermos cups used by people at present are generally made of materials such as double-layer stainless steel, glass, ceramics and the like.
Although the thermos cup brings convenience to life of people, the function of the traditional thermos cup is only limited to delay heat exchange of solution in the cup body, and the thermos cup has singleness and has various inconveniences and insecurities in the use process. Firstly, for the freshly poured solution of hot water, tea, coffee and the like, the temperature of the solution in a container is generally reduced after long waiting time and the like are needed when people drink the solution, and when the freshly brewed high-temperature tea, coffee and the like are not cooled to a temperature suitable for drinking, the people drink the solution, so that the burning of organs such as lip skin, the inner side of an oral cavity, esophagus, intestines and stomach and the like is easily caused, and serious consequences are caused. Secondly, because the vacuum cup has good heat preservation effect, the temperature of 100 ℃ boiled water is generally required to be reduced to 65 ℃ for 3-6 hours, and people usually can open the cover of the vacuum cup to dissipate heat in order to obtain a temperature suitable for drinking as soon as possible, but even though the waiting time is long, people who drink urgently can continuously try to find out whether the temperature of surface liquid is suitable for drinking or not by mouth, so that the lips and the oral cavity are often scalded. In order to solve the problem that water with proper temperature needs to be drunk in a short time, a vacuum cup in the prior art adopts a thermal phase change technology, liquid capable of absorbing heat is added into a gap layer, and the heat of the liquid in the cup is rapidly absorbed through shaking to reduce the temperature, so that all the liquid in the cup is simultaneously reduced in temperature, and the long-acting heat preservation function of the vacuum cup is lost. Therefore, there is a need for a thermos cup that can rapidly lower the temperature of the liquid to be drunk while maintaining a long-term insulation to make it suitable for drinking, which has been overlooked and lacking in the prior art.
Taking coffee as an example, people like hot coffee like tea, coffee and the like have a great interest in obtaining good taste because the aroma volatile aroma contained in hot coffee liquid is emitted by heating, so that the coffee smells strong and tastes special flavor, the temperature of the coffee often determines the taste of the coffee and the volatile gas quantity of aroma volatile component compounds contained in the coffee liquid in a drinking inlet, the best hot water brewing temperature of the known coffee is 90-95 ℃, the temperature generally recommended for the coffee liquid in the drinking inlet is 55-65 ℃, and thus the concentration of the aroma volatile component compounds in fresh coffee entering a nasal cavity is best, and the coffee liquid can be prevented from becoming sour and bitter. Generally, in order to quickly cool brewed coffee to a temperature suitable for drinking, people can place the brewed coffee in a cup and open the cup in the air, so that the heat of coffee liquid in the cup is continuously reduced, aromatic volatile aroma component compounds contained in the coffee liquid in the cup are volatilized slowly in the air, at the moment, the coffee liquid becomes sour and bitter, and is not fragrant and delicious, so that the coffee liquid which is not drunk up in the cup can be discarded frequently. Therefore, a vacuum cup which can delay the overall coffee liquid temperature emission speed in the cup so that coffee can be drunk for a longer time and can keep the coffee liquid temperature of each drinking inlet between 55 and 65 ℃ at the optimal drinking temperature is a key for solving the problem and is lacking in the prior art.
In a similar way, the heat preservation devices such as the heat preservation lunch box and the heat preservation soup pot which are usually used by people all have the same defects, and when the long-time heat preservation effect is pursued, due to the integral heat preservation design of the heat preservation device, the temperature which is suitable for eating or drinking can not be quickly reduced by a simple and quick mode, so that the use is inconvenient. An insulating device capable of rapidly lowering the temperature of a desired liquid or food to make it suitable for drinking or eating while maintaining a long-term insulation is overlooked and lacking in the prior art.
