Abstract

The invention provides a multifunctional solar energy heating and heat preservation lunch box which comprises a solar panel, a box cover, an outer casing, an intermediate casing, an inner casing, a storage battery, a heater strip, a water storage layer, a vacuum layer, a lunch box main body, a charging jack, a storage battery switch, a conducting wire, a metal contact, a water storage layer cover, a movable handle and an insulating layer. According to the invention, the storage battery can be charged through the solar panel and can also be charged by a power supply; the storage battery supplies power to the heater strip to heat the water storage layer, so that food can be heated and kept warm, and hot water for drinking can be supplied; and a double-layered vacuum casing is arranged between the intermediate casing and the outer casing, so that the heat preservation effect is better, and the multifunctional solar energy heating and heat preservation lunch box is very suitable for people needing to take food in daily work and people going out for playing.

Description

technical field [0001] The invention relates to a lunch box, in particular to a multifunctional solar heating and heat preservation lunch box. Background technique [0002] When people go to work, they often need to bring food and water with them, but now many lunch boxes do not have the function of heating, let alone the function of heating hot water. People often eat cold rice and cold dishes. On the one hand, the food has no taste when it is cold. On the one hand, it is not conducive to human health. There are some heated lunch boxes on the market, some can only be heated by electricity, and some are heated by chemical reaction or fuel, but the use of chemical fuel will pollute the environment. Solar energy is a kind of clean energy, its technology has been developed relatively mature, and it is convenient and easy to obtain. There is no sale on the market of the multifunctional heating lunch box combining power supply and solar energy. Contents of the invention [0...
