Abstract
The utility model discloses an automatic heating lunch box which comprises a box body and a box cover, wherein one side of the box cover is hinged to the box body, and the other side of the box cover is clamped with the box body in a sealed mode; a solar cell is arranged on the upper surface of the box cover; the box body comprises a shell and a liner; a storage battery, a charging and discharging controller and a heating wire are arranged at the bottom of an inner cavity of the shell; a control switch for controlling current conduction of the heating wire is arranged on the box body; the solar cell and the charging and discharging controller are electrically connected with the storage battery; the heating wire, the control switch and the storage battery are electrically connected with one another. The solar cell collects solar energy and converts the solar energy into electric energy for charging the storage battery, and the storage battery supplies power to the heating wire, so that the heating wire generates heat to heat foods in the liner. When the temperature in the liner reaches a certain value, the heating wire automatically stops heating and is kept in a constant temperature state, and when the lunch box is not used, the control switch is switched off. The lunch box is particularly suitable for students, has an energy-saving effect and is convenient to use, and the students can eat hot meals with the automatic heating lunch box.
Description
Technical field
The utility model relates to a kind of automatic heating lunch box.
Background technology
