Обычные термосы способны лишь сохранять тепло., в то время как термосы, которые могут вскипятить воду (также известный как “самонагревающиеся термосы”) может быстро вскипятить воду посредством химических реакций или электрического нагрева без источника питания. Этот тип продукта подходит для путешествий на открытом воздухе., командировки, или экстренное использование.
1. Heating principle of a thermos cup that can boil water
There are currently three main heating methods on the market
(1) Electric heating insulated cup (requires power supply)
A. Принцип: Built in electric heating tube, powered by USB/Type-C or car power supply (usually 12V-24V).
Б. Функции: Can be heated to 100 ℃, some support constant temperature insulation (такой как 55 ℃, 70 ℃), power is generally between 50W-100W, занимает 5-10 minutes to boil a cup of water. Suitable for office and car use, but dependent on power supply.
(2) Chemical self heating insulated cup (no power required)
A. Принцип: By utilizing the chemical reaction of magnesium powder, iron powder, and salt, heat is released after adding water, causing the water temperature in the cup to rise.
Б. Функции: Can be heated to 60-80 ℃ in 3-5 минуты, disposable, non reusable. Suitable for outdoor emergencies, but the cost is relatively high.
(3) Solar heated insulated cup
A. Принцип: The cup body adopts a solar heat absorbing coating and is heated by concentrated light reflection.
Б. Функции: Slow heating (30-60 minutes to heat up), greatly affected by weather. Suitable for camping, but less practical.
2. Меры предосторожности при использовании
(1) Electric heating cup: Avoid dry burning without water, which may damage the heating element. Some products do not support automatic power-off after boiling and require manual control.
(2) Chemical self heating cup: produces hydrogen gas during heating and needs to be used in a ventilated environment. Cannot hold beverages, otherwise harmful substances may be produced.
(3) Solar cup: Poor effect on cloudy days, suitable for sunny areas.
