Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-3, the present utility model provides a technical solution: a self-heating portable hand warmer, comprising a hand warmer 1, an interlayer 2 is opened inside the front side of the hand warmer 1, and a front side of the hand warmer 1 is provided. The left side is provided with an opening 3, the outside of the opening 3 is movably connected with a flip 4, the lower end of the flip 4 is provided with a buttonhole 5, the bottom of the opening 3 is fixedly connected with a button 6, the buttonhole 5 is movably connected with the button 6, the opening 3 and the interlayer 2 In the interlayer 2, the mobile power supply 7 and the hot water bottle 11 are movably connected, the mobile power supply 7 and the hot water bottle 11 are movably connected through the connection port 9, the upper end of the mobile power supply 7 is provided with a charging hole 8, and the upper end of the mobile power supply 7 is fixedly connected with a switch 10, The upper right corner of the hot water bottle 11 is provided with a water exchange port 13, which is movably connected with the water exchange port cover 12, and a waterproof casing 14 and a heating ring 15 are fixedly connected in the hot water bottle 11, and the heating ring 15 is movably connected with the connection port 9.
