The waterproof insulation layer 1 is filled with a filling liquid 4 that can be heated. The inner wall of the waterproof insulation layer 1 is fixedly connected to a heating unit 5. The waterproof insulation layer 1 can be made of a dual material of waterproof material as the inner layer and thermal insulation material as the outer layer. It can be made by fitting and fixing, or it can be directly made of waterproof and heat-insulating materials. There are already a large number of such materials on the market, so no specific examples are given here; the filling liquid 4 can be supersaturated salt solution or water; heating Unit 5 includes a temperature sensor, a controller and a heater. The temperature sensor is installed in the waterproof insulation layer 1 to detect the temperature of the filling liquid 4 and transmit the temperature signal to the controller. When the filling liquid 4 reaches a certain temperature, the controller controls the heater. Start or stop operation; the heater can use heating sheets, heating rods, resistance wires and other elements that can generate heat after being energized;

Covering layer 2, the covering layer 2 is provided on the surface of the waterproof insulation layer 1; the covering layer 2 can be made of soft materials, such as silica gel, cotton layer, etc., to improve the user's comfort during use;
