The utility model provides a hand warmer.

In an embodiment of the present utility model, as shown in fig. 1 to 3, the hand warmer includes: a housing 10, wherein the housing 10 is provided with a receiving cavity 11 and a drawing port communicated with the receiving cavity 11; the rotating and winding piece 20 is rotatably arranged in the accommodating cavity 11, and the drawing port is positioned on the periphery side of the rotating and winding piece 20; the enclosing and hanging belt 30 comprises an enclosing and hanging body 31, a hanging rope 32 and a connecting body 33, wherein the hanging rope 32 is wound on the rotating and winding piece 20, and the hanging rope 32 can be pulled out of the containing cavity 11 through the drawing opening or wound back into the containing cavity 11 by the rotating and winding piece 20; the connecting body 33 fixedly connects the surrounding hanging body 31 with the hanging rope 32, and the hardness of the connecting body 33 is greater than that of the surrounding hanging body 31.

In this embodiment, the casing 10 is specifically configured to form an overall appearance structure of the hand warmer, and the casing 10 may be rectangular, cylindrical or spherical, which is not limited herein. For example, the housing 10 may be cobble-shaped for easy grasping by a user. The rotating member 20 may be hollow, cylindrical or solid, and is not limited herein, and may be rotated in the accommodating cavity 11 and wound with the hanging rope 32. The turn-around member 20 has a peripheral surface and two end surfaces, and the drawing port is opposed to the peripheral surface of the turn-around member 20. During outward stretching of the hanging rope 32, the force is transmitted to the rotating member 20, and the rotating member 20 rotates synchronously to gradually release the hanging rope 32. The other end of the hanging rope 32 may be connected to the winding member 20 to prevent the hanging rope 32 from being difficult to retract after being completely pulled out of the receiving cavity 11.

When it is desired to retract the hanging cord 32, the user can wind the hanging cord 32 back into the receiving chamber 11 by driving the rotating member 20 to rotate in the opposite direction. The driving of the winding member 20 may be by means of a driving motor, or may be manually or by means of a reset spring 50 or a reset spring piece, which is not limited herein; it is only necessary that the turnbuckle 20 be rotatable to retract the lanyard 32.

For example, the hand warmer further comprises a reset spring 50 mounted in the accommodating cavity 11, the reset spring 50 is connected with the winding member 20, and the reset spring 50 is used for winding the hanging rope 32 by driving the winding member 20 to reset and rotate. When the hanging rope 32 is pulled out of the accommodating cavity 11 and the winding piece 20 rotates forward, the winding piece 20 elastically deforms the reset spring 50 to accumulate elastic potential energy; when the tension on the hanging rope 32 is removed, the reset spring 50 is elastically restored to drive the turning piece 20 to turn, so that the hanging rope 32 can be automatically wound up.

The enclosure body 31 may be provided as a flexible band to facilitate bending deformation and improve the tactile experience for the user. The enclosing and hanging body 31 can be switched between a storage state and an unfolding state, when a user needs to use the hand warmer, the enclosing and hanging body 31 enters the unfolding state, and at the moment, the enclosing and hanging body 31 is unfolded relative to the shell 10 and encloses and forms an enclosing and hanging space. The surrounding space may be formed by surrounding the surrounding body 31 after the surrounding body is in the unfolded state, or may be a shape in which the surrounding body 31 is kept surrounding the neck hanging space at any time, which is not limited herein.

After the enclosing and hanging body 31 enters the unfolding state, a user can enclose and hang the enclosing and hanging body 31 on the neck, so that the shell 10 is kept at a position capable of contacting the body, and then the heat is generated through the heating sheet 40; the heat generating sheet 40 may generate heat by electric energy or chemical energy, and is not limited herein. The heat emitted from the heat generating fins 40 is transferred to the body part of the user through the housing 10 for heating the user.

After the hand warmer is used, the user can switch the surrounding hanging body 31 to a storage state, and the surrounding hanging body 31 is close to the shell 10. It will be appreciated that the enclosure 31 and the connector 33 are always located outside the housing 10, and that a portion of the hanging cord 32 connected to the connector 33 is also always located outside the housing 10. When the hanging rope 32 is pulled outwards, the surrounding hanging body 31 and the connecting body 33 are relatively far away from the shell 10; when the hanging rope 32 is wound up, the surrounding hanging body 31 and the connecting body 33 are relatively close to the casing 10.

The connection between the hanging rope 32 and the enclosing hanging body 31, namely the connection between the connecting body 33 and the enclosing hanging body 31 and the hanging rope 32, because the hardness of the connecting body 33 is higher, the connecting body 33 can increase the structural strength of the connection between the enclosing hanging body 31 and the hanging rope 32, so that the friction or other acting force of the hanging rope 32 can not directly act on the enclosing hanging body 31, and the abrasion to the enclosing hanging body 31 is reduced.

In the technical scheme of the hand warmer, the surrounding hanging body 31 and the hanging rope 32 are mutually fixed through the connecting body 33 with higher hardness, the acting force of the hanging rope 32 can be born by the connecting body 33, and the connecting body 33 is more hard to wear and deform due to higher hardness, so that the overall structural stability of the surrounding hanging body 31 can be improved; the surrounding hanging body 31 with smaller hardness can ensure wearing comfort of a user so as to improve user experience.
