Temperature, relative to using low melting point phase-change metal to be used to cool down completely, reduces thermostatic glass cost, while also mitigate weight.Adopt
Heat is absorbed in cooling with inorganic hydrated salt compound phase solution and phase-change metal, latent heat of phase change is released when drink temperature reduces
For keeping the temperature, inorganic hydrated salt compound phase solution is at the same time as heat medium when keeping the temperature.When heat release is completed, drink temperature is into one
When step reduces, kept the temperature using microwave heating to the temperature of setting.Can be quickly by hot drink（Reach as high as 100 DEG C）Rapidly（About
60 seconds）It is cooled to potable temperature（40 DEG C -60 DEG C related to drink species）, and keep permanent for a long time by microwave heating
Constant temperature degree.
Solid state microwave sources use GaN（Gallium nitride）Semiconductor power amplification pipe, operating voltage are low（Direct current 50V）, can adopt
Powered with internal battery.Relative to 4000 volts of high pressures needed for conventional magnetron pipe microwave generator, the height in complex and expensive can be saved
Generation device is pressed, cost is lower, security higher.Solid state microwave sources use GaN（Gallium nitride）Semiconductor power amplification pipe, than
LDMOS（Laterally Diffused Metal Oxide Semiconductor, lateral diffusion metal oxide semiconductor）
Semiconductor power amplification tube efficiency improves 10%, and power density improves 3-4 times, and antenna volume can be made minimum, further reduce phase transformation
The volume of liquid heating chamber so that constant temperature cup volumes can be suitable with common thermal insulation cup.When temperature further reduces, inorganic hydrated salt
When the sensible heat and latent heat treatment of composite phase-change liquid and low melting point phase-change alloy finish, inorganic hydrated salt is heated using microwave heating effect
The shortcomings that moisture in composite phase-change solution, avoids the length of traditional Electric heating time of use " Joule effect ", and efficiency is low,
Reach long-time heat preservation purpose.
