Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: this utility model comprises hand warmer bag body and to the charging rack of hand warmer bag body electrified regulation, heating wire and restorability thermal protector RT is provided with in hand warmer bag body, charging rack has the power line connecting civil power, described hand warmer bag body is provided with two core sockets, described charging rack is provided with the holes plug with two core socket couplings, the a1 pole of two core sockets, b1 pole respectively with a pole of holes plug, b is extremely connected, the a1 pole of two core sockets is connected with described restorability thermal protector RT, the electromotion pilot lamp of hand warmer bag body is located on described charging rack, control circuit is provided with in charging rack, control circuit comprises inductive coupler L, controllable silicon G and light emitting diode D, light emitting diode D is exactly described electromotion pilot lamp, the positive pole of controllable silicon G is connected with the negative pole of light emitting diode D, the negative pole of controllable silicon G is extremely connected with the b of the holes plug of charging rack, the b pole of holes plug is extremely connected with the input power B of charging rack, the control pole of controllable silicon G is connected with the negative pole of controllable silicon G through the secondary coil L2 of inductive coupler L, the positive pole of light emitting diode D is extremely connected with the input power A of charging rack, input power A pole is extremely connected with a of the holes plug of charging rack through the primary coil L1 of inductive coupler L.During with charging rack to hand warmer bag body electrified regulation; the a1 pole of two core sockets of hand warmer bag body, b1 pole are extremely connected with a pole of the holes plug of charging rack, b respectively; again the power line of charging rack is connected civil power; heating wire now in hand warmer bag body obtains electric heating; controlled silicon conducting; light emitting diode is lighted; along with the water temperature in bag slowly raises; restorability thermal protector RT works; disconnecting circuit; then light emitting diode extinguishes, and the microswitch simultaneously on charging rack disconnects, and charging rack stops powering to hand warmer bag body.Because electromotion pilot lamp of the present utility model is located on charging rack, therefore can guarantee the sealing property of bag, improve safety, between charging rack and hand warmer bag body, adopt two core connectors to connect simultaneously, decrease angle, improve contact reliability.
Certain control circuit also can adopt relay to replace controllable silicon to realize, and the normally opened contact switch of relay and light emitting diode series connection, the drive end of relay is connected with restorability thermal protector.When relay is driven, then its normally opened contact switch connection, light emitting diode is lighted.
As preferably, described control circuit comprises electric capacity C and resistance R, and the secondary coil L2 of the inductive coupler L that electric capacity C, resistance R are equal and described is in parallel.
As preferably, described restorability thermal protector RT is close to the medial surface of described hand warmer bag body.The temperature that restorability thermal protector is sensed and bag surface temperature close, guarantee user catch tactile bag time the temperature felt meet heating requirement.
The beneficial effects of the utility model are: electromotion pilot lamp is located on charging rack, improve the sealing of hand warmer bag body, reduce potential safety hazard; Between charging rack and hand warmer bag body, adopt two core connectors to connect, reduce angle, improve contact reliability.
