Abstract
The utility model relates to a structure for installing an electric-heating device of an electrothermal hand warmer, which comprises a bag chamber. The electric-heating device is arranged inside the bag chamber. The electric-heating device comprises an isolation cover and an electric-heating body fixed inside the isolation cover. The structure is characterized in that a fixing rod is arranged on the outer surface of the isolation cover; and the fixing rod is fixedly connected with the inner wall of the bag chamber. By arranging the electric-heating body inside the isolation cover and further fixing the electric-heating device inside the bag chamber through the fixing rod, the structure provided by the utility model prevents the electric-heating device from being in a dissociated state and further prevents the electric-heating body from being exposed out of a heat storage liquid surface due to the inclination of a bag body or heating expansion and resulting in dry burning accidents. The electric-heating body which is placed inside the isolation cover is fully prevented from contacting the inner wall of the bag chamber. The bag body is thus prevented from being burnt. The service lifetime of the electrothermal hand warmer is thus effectively prolonged.
