Multifunctional lunch box

Abstract

The invention discloses a multifunctional lunch box comprising a box body, a box cover arranged on the box body and a handle arranged on the box cover. The multifunctional lunch box is characterized in that a generator is arranged in the box cover, one end of the handle is rotationally connected with a connecting rod, the other end of the handle is detachably connected with the surface of the box cover, the connecting rod penetrates through the shell of the box cover to be fixed on the rotor of the generator, and when the connecting rod drives the rotor to rotate, an annular groove is formed in the surface of the box cover along the movement orbit of the connecting rod. The generator is shook by a hand to generate power to finish such works as cooking, charging, and the like, and the multifunctional lunch box is reasonable in structural design, smart and novel in conception, complete in functions, convenient to use, convenient to carry and beautiful and elegant in appearance.

Description

technical field [0001] The invention belongs to lunch boxes, in particular to a multifunctional lunch box capable of automatically generating electricity. Background technique [0002] In people's daily life, lunch boxes are often used to deliver or bring meals to facilitate work, study or take care of patients. At present, various styles of thermal insulation lunch boxes have appeared on the market for people to use. Existing thermal insulation lunch boxes usually include a lid, a shell and an inner pot. In order to keep warm for a long time after heating, some heat-insulating lunch boxes are also equipped with a heat-insulating structure in the shell. By reducing the heat transfer efficiency inside and outside the heat-insulating structure, the heat transfer speed inside and outside the shell is slowed down, thereby achieving long-term heat preservation. the goal of. However, the manufacturing cost of the thermal insulation structure with good thermal insulation effec...
