A foldable food warming pad, comprising:
- a panel, being bendable and provided with a heat source;
- and the heat source being configured to form a heating area on a first surface of the panel;
- and
- a controller comprising:
- a housing, a main control circuit board, and a battery;
- the main control circuit board and the battery being arranged in the housing;
- the heat source and the battery being electrically connected to the main control circuit board respectively;
- and the panel being fixedly connected to a first side of the housing;
- wherein the panel comprises a second surface opposite to the first surface, the second surface of the panel is provided with a plurality of support bodies, the plurality of support bodies are parallel to the first side of the housing, and the plurality of support bodies extend in a direction away from the second surface of the panel, a thickness of the panel is smaller than a thickness of the housing, and a height of the plurality of support bodies is configured to compensate for a thickness difference between the panel and the housing;
- wherein the foldable food warming pad is bendable in a manner that, in a first state, the first surface of the panel is coplanar with an upper surface of the controller, and the first surface of the panel extend from an edge of the controller toward a direction away from the controller;
- and in a second state, at least one of the plurality of support bodies abuts against a lower surface of the controller.
