Abstract

The invention relates to an electric heating box for double feet, comprising a box body E, foot rests D, a heating element C, warm keeping foot sleeves B which are tightly hooped on a box edge 6, and the like. Because the heating element of a traditional heating box is directly connected with the mains supply through a simple silicon controlled voltage regulation circuit, the heating element and a power supply have no electric isolation, a heated part of the human body is a certain distance from the heating element while heating, and heat generated by the heating element is transmitted to the human body in a radiation mode; and moreover, the traditional heating element has no warm keeping measures, thus great heat loss is caused, and the use of the traditional heating element has the defects of unsafety and energy waste. In the electric heating box for double feet, safety voltage is used for supplying power to the heating element, the heated part of the human body is in direct contact with the heating element, and the heat generated by the heating element is transmitted to the human body mainly in a conduction mode. In addition, the warm keeping foot sleeves and the warm keeping box body form a tight heating chamber to ensure that the heat loss is less, the heating power required by the human body to absorb the same quantity of heat is greatly reduced, and the electric heating box is safe to use and saves energy.
