Abstract

An electric heating device with constant power comprises a power supply module, a plurality of electric heating elements and a switching unit. The power supply module obtains a direct-current power supply of any battery among various batteries with different input voltages in a matched manner, the electric heating elements are provided with loads, the loads can be driven by electric energy of the direct-current power supply to generate heat energy, and the switching unit switches different loads according to the different input voltages, so that the output power applied to the loads is controlled within a constant range. As the electric heating device is applicable to the various batteries, consumers can conveniently use the electric heating device, and manufacturers also easily control materials / parts.

Description

technical field [0001] The present invention relates to an electric heating device, in particular to a fixed power electric heating device that can maintain a fixed output power in conjunction with multiple input voltages. Background technique [0002] In the cold season, wearing close-fitting electric heating clothes or electric heating boots is an indispensable way to keep out the cold. In order to facilitate movement, battery power must be used. [0003] refer to figure 1 and figure 2 , a known electric heating device mainly includes a control box 940 and a heating wire 913 . [0004] The heating wire 913 itself is bent into several bending sections to uniformly heat a predetermined area, and the heating wire 913 can also be replaced by a tubular or block heating element; the heating wire 913 and the control box 940 are electrically connected by a wire 914 . [0005] The control box 940 has a control circuit 920 and a battery pack 930. The control circuit 920 has a sw...
