Through the above structure, due to the first hand warmer unit and the second hand warmer unit, the first hand warmer unit is provided with the first connecting portion, and the second hand warmer unit is provided with the second connecting portion; the first connecting portion and the second connecting portion are detachably connected, so that the first hand warmer unit and the second hand warmer unit are combined into a whole. When a user needs to use the hand warmer to simultaneously warm the hands/multiple body parts, the first hand warmer unit can be separated from the second hand warmer unit, so that the first hand warmer unit and the second hand warmer unit can be used for warming the two hands/multiple different body parts respectively. When a user only needs to use the hand warmer to warm one hand/one body part, the first connecting portion can be connected to the second connecting portion to combine the first hand warmer unit with the second hand warmer unit into a whole, so as to enlarge a warming area of the hand warmer for one hand/one body part and improve the warming effect. Furthermore, when a user needs to carry or store the hand warmer, the user can select to separately carry and store the first hand warmer and the second hand warmer according to an actual situation, or select to combine the first hand warmer with the second hand warmer into a whole to satisfy the use in multiple scenarios by a user, which greatly improves the user experience.

The second buckle portion is a second buckle slot 32, and the second buckle fitting portion is a second buckle 42. When the first buckle 31 is detachably plugged into the first buckle slot 41, the second buckle 42 is detachably plugged into the second buckle slot 32. Through the above structure, the structure is simple, the connection is stable, and the detachable connection between the first connecting portion and the second connecting portion is effectively achieved. Moreover, in this embodiment, the detachable connection between the first connecting portion and the second connecting portion can be further achieved by using a detachable connection mode such as male and female snappers and male and female hook and loop fasteners.

In this embodiment, the first connecting portion 3 further includes a first positioning column 33, and the second connecting portion 4 further includes a first positioning hole 43; and when the first positioning column 33 is located in the first positioning hole 43, the first buckle 31 is detachably plugged into the first buckle slot 41, and the second buckle 42 is detachably plugged into the second buckle slot 32. The first connecting portion 3 further includes a second positioning hole 34, and the second connecting portion 4 further includes a second positioning column 44; and when the first positioning column 33 is located in the first positioning hole 43 and the second positioning column 44 is located in the second positioning hole 34, the first buckle 31 is detachably plugged into the first buckle slot 41, and the second buckle 42 is detachably plugged into the second buckle slot 32.
