[0002] The current development direction is to use semiconductor thermoelectric power generation chips and use the waste heat of the equipment to generate electricity. For example, Chinese patent document CN 205619389U discloses a power generation device suitable for a picnic gas stove, and proposes a scheme to use the waste heat of the stove body to generate electricity. In the prior art, other waste heat power generation stoves, including this stove body, have a common disadvantage: the existing thermoelectric power generation kettle mainly sets a thermoelectric chip at the bottom, and uses the bottom heat dissipation temperature difference and water temperature difference to generate electricity, but the power generation power is small and the waste heat temperature that is not dissipated into the air is high and not fully utilized. In addition, due to the underutilization of heat, the handle of the kettle becomes hot when it is taken off, which can easily burn your hands.

[0003] Therefore, the technical problem to be solved by the present invention is: how to recycle the waste heat as much as possible and convert the waste heat into electrical energy. Summary of the invention
