[0002] At present, the electric rice cooker of the prior art includes a pot body and a cover body, wherein the cover body includes a temperature-sensing bag, a heat-insulating cover plate and an upper cover injection molded part, wherein the temperature-sensing bag is sealed with the heat-insulating seat plate through a sealing ring, and the sealing ring is pressed on the upper cover injection molded part by the heat-insulating cover plate, and the temperature-sensing bag penetrates into the pot body through the hole on the sealing ring and the hole on the heat-insulating cover plate to detect the temperature in the inner cavity of the pot body when cooking. This method of setting the temperature-sensing bag is not suitable for setting the float in the micro-pressure electric rice cooker, because during the cooking process, the air pressure in the inner cavity of the pot body is greater than the atmospheric pressure, and the fastening strength of the heat-insulating cover plate itself is insufficient. If the heat-insulating cover plate is used to fix the sealing ring at this time, the sealing ring will be pushed open by the air pressure and cannot be used normally. In addition, since the heat-insulating seat plate is large, it is easy to block the line of sight during assembly, resulting in the installation of the float being offset and inconvenient to operate.
