Self-heating lunch box based on single-chip microcomputer

Abstract

The invention provides a self-heating lunch box based on a single-chip microcomputer. The lunch box comprises a lunch box body, and a containing groove is formed in the upper side in the lunch box body; a partition plate is arranged in the middle of the containing groove, and a temperature detection module is arranged in the middle of the partition plate; an inner meal box is placed in the containing groove; a temperature control module is arranged on the lower side of the containing groove; a control cavity is formed in the lower side in the lunch box body; a heat-insulating plate is arrangedon the upper side of the control cavity; a battery jar is arranged on the right side in the control cavity; a power module is placed in the battery jar, a single-chip microcomputer control module, atime setting module and a temperature setting module are arranged on the left side in the control cavity, a touch screen is arranged on the surface of the outer side of the control cavity, and the single-chip microcomputer control module is electrically connected with the time setting module, the temperature setting module, the temperature control module, the temperature detection module, the power module and the touch screen. The heating time and the heating temperature are set through the time setting module and the temperature setting module, the single-chip microcomputer controls the temperature control module to heat the inner lunch box, intelligent control over the lunch box is achieved, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to the field of lunch box heating, in particular to a self-heating lunch box based on a single-chip microcomputer. Background technique [0002] Office workers, students often need to bring meals when they go to school or take care of patients. The existing common lunch boxes are only used to hold food such as meals. The heated lunch box mainly uses the power module and the heating liner to realize the heating function. The existing electric lunch boxes are generally only equipped with a heating function. After the heating is completed, the user needs to press the switch to stop the heating of the electric lunch box. [0003] The electric heating lunch box is in front of it, so the electric heating lunch box may be in a heating state for a long time, which will affect the taste of the food and easily cause damage to the electric heating lunch box. So it becomes very important to solve this problem. Contents of the invention ...
