As shown in fig. 3, the hand warmer further includes a hanging rope 70 and a winding member 60, the casing 10 is provided with a drawing port, the winding member 60 is rotatably installed in the casing 10, the hanging rope 70 is at least partially wound around the winding member 60, and the hanging rope 70 can be pulled out of the installation cavity 11 through the drawing port or wound back into the installation cavity 11 by the winding member 60; the rotating member 60 is linked with the control module 30, and when the rotating member 60 rotates, the control module 30 is triggered to start the display screen 20.

The hand warmer has two using modes, one is directly held by the hand and the other is hung on the body part of the user. In the idle state or the hand-held use state of the hand warmer, the hanging rope 70 is wound on the winding piece 60 in a winding manner and is hidden in the installation cavity 11. When it is desired to hang the hand warming bag on a body part, such as the neck, the user can grasp the hanging cord 70 and pull it outwardly from the pull opening to pull the hanging cord 70 out of the mounting cavity 11. During the pulling of the hanging rope 70, the acting force is transmitted to the rotating and winding member 60, and the rotating and winding member 60 rotates synchronously to release the hanging rope 70 gradually. The other end of the hanging string 70 may be connected to the swivel 60 to prevent the hanging string 70 from being difficult to retract after being completely pulled out of the installation cavity 11. After the hanging rope 70 is pulled out of the installation cavity 11, a user can wind or bind the hanging rope 70 on a preset part of the body, so that the hand warmer can heat near the body surface without holding the hand.

The winding member 60 may have a cylindrical shape or a cylindrical shape, a square cylindrical shape or a square cylindrical shape, or may have other irregular shapes, and is not limited herein, and may be rotated in the installation cavity 11 and wound with the hanging rope 70.

After the hand warmer is used, the user can wind the hanging rope 70 back to the installation cavity 11 by driving the rotating and reverse rotating. The driving of the winding member 60 may be by a driving motor, or may be by a manual operation or by a reset spring or a reset spring piece, which is not limited herein; it is only necessary that the swivel member 60 be rotatable to retract the hanging cord 70.

The linkage of the winding member 60 and the control module 30 may be mechanical linkage, or may be triggered by an inductive switch, which is not limited herein. It is only necessary to trigger the control module 30 to turn on the display screen 20 when the rotating member 60 rotates. For example, a magnetic member is mounted on the winding member 60, and the control module 30 is connected to a magnetic induction switch, and when the hanging rope 70 is not pulled out, the magnetic member is in an initial position, which may be a position close to the magnetic induction switch. When the hanging rope 70 is pulled out, the rotating member 60 rotates, and the magnetic member synchronously rotates to change the relative position with the magnetic induction switch, so that the magnetic induction switch is triggered, and the control module 30 is triggered. That is, each time the hanger wire 70 is pulled to rotate the rotating member 60, the magnetic member moves away from the initial position to trigger the magnetic induction switch. Therefore, the user can randomly display the graphic information on the display screen 20 by pulling the hanging rope 70 each time, so as to obtain different visual experiences.

As shown in fig. 2 and 3, the hand warmer further includes a battery and a surrounding hanging belt 80, the battery is mounted in the mounting cavity 11, the surrounding hanging belt 80 is movably disposed on the outer wall of the casing 10, and the surrounding hanging belt 80 is connected to the outer end of the hanging rope 70; the heating element comprises a heating sheet arranged in the surrounding hanging belt 80, and a wire is arranged in the hanging rope 70 and electrically connects the battery with the heating sheet. The strapping 80 is intended to be worn by a user on a body part, such as the neck; the hanging rope 70 is used for realizing movable connection between the surrounding hanging belt 80 and the shell 10, so that the distance between the surrounding hanging belt 80 and the shell 10 can be increased or reduced, and the wearing of a user is facilitated. The heating element can increase the temperature of the surrounding hanging belt 80, so that the body part of the user can be effectively warmed through the surrounding hanging belt 80, and the warming effect is improved. The lead is threaded through the hanging rope 70, so that a conductive rope can be formed by the lead and the hanging rope 70, and the conductive rope can realize the physical connection between the surrounding hanging belt 80 and the shell 10 and the electric connection between the battery and the heating piece, thereby improving the effective utilization rate of the hanging rope 70.

Illustratively, the hand warmer further comprises a circuit board and an adjusting key, wherein the circuit board is installed in the installation cavity 11, the adjusting key is installed in the shell 10, and the adjusting key, the wires and the battery are all electrically connected with the circuit board. Through setting up the regulating key, the user can control the temperature of piece that generates heat at any time to control encloses the temperature of hanging area 80, so that the user can adjust the temperature of hand warmer according to self heating demand, further improves user experience.
