Referring to
The hand warmer body 1 includes outer shell 11, heating film 13 disposed on each of two sides of the outer shell 11, and aluminum alloy thermally-conductive cover plate 15 covered on the heating film 13.
The outer shell 11 is internally provided with Hall switch 114 that is tightly attached to the first surface and magnetic steel 115 located on a side of the Hall switch 114. When the first surfaces of the two hand warmer bodies 1 are opposite and attached to each other, Hall switches 114 and magnetic steels 115 inside the two hand warmer bodies 1 are opposite, and the Hall switches 114 are triggered. A switch-type Hall sensor is mainly configured to measure a quantity of revolutions, a revolving speed, a wind speed, a flow rate, a proximity switch, a door closing notification device, an alarm apparatus, and an automatic control circuit. In this embodiment, the Hall switch 114 is configured to disconnect the heating film 13 located on the flat surface of the outer shell 11, as shown in
Specifically, there is at least one Hall switch 114 and at least one magnetic steel 115 inside the outer shell 11, as shown in
Specifically, the two sides of the outer shell 11 each are provided with heat insulation groove 12, and the heating film 13 is disposed inside the heat insulation groove 12. With the heat insulation groove 12, the overhead heating film 13 is away from battery 16, reducing an impact of heat on the battery 16.
Specifically, the heat insulation groove 12, the heating film 13, and the aluminum alloy thermally-conductive cover plate 15 that are located on a cambered surface of the outer shell 11 are all arc-shaped, while the heat insulation groove 12, the heating film 13, and the aluminum alloy thermally-conductive cover plate 15 that are located on a flat surface of the outer shell 11 each have a flat surface. The heat insulation groove 12 is internally provided with waterproof ring 14, which is used for sealing treatment between the aluminum alloy thermally-conductive cover plate 15 and the heat insulation groove 12.
Specifically, the hand warmer body 1 is internally provided with the battery 16 and the circuit control board 17 electrically connected to the battery 16, the heating film 13, and the Hall switch 114, and the circuit control board 17 is provided with a switch and a charging interface.
Specifically, the outer shell 11 is provided with waterproof switch button 111 and waterproof charging rubber plug 112 that are respectively corresponding to the switch and the charging interface. The waterproof switch button 111 and the waterproof charging rubber plug 112 are respectively used for waterproof treatment of the switch and the charging interface.
Specifically, the two sides of the outer shell 11 each are provided with non-slip rubber strip 19. The non-slip rubber strip 19 provides more comfortable grasping, absorbs sweat, and is not easy to slip off.
Specifically, a magnet is provided on the flat surface inside the outer shell 11. Through the magnet, the two hand warmer bodies 1 can be tightly adhered together. Magnets of the two hand warmer bodies 1 have opposite magnetic properties and attract each other.
Specifically, the outer shell 11 includes an upper shell and a lower shell, shell sealing ring 18 is provided between the upper shell and the lower shell, and the shell sealing ring 18 is provided with rubber strip sealing ring 181 attached to the non-slip rubber strip 19.
