That is, the inner wall of the recessed portion 52 and the belt body 20 are surrounded to form a storage cavity 50. Furthermore, the storage cavity 50 and the housing 10 are an integrated structure, and the processing is simple.

[0036] In this embodiment, a plurality of through holes 53 are provided on the cavity wall of the storage cavity 50, and the plurality of through holes 53 are arranged at intervals along the circumference of the recessed portion 52. One side of the through hole 53 is connected to the air duct 13, and the other side of the through hole 53 is connected to the storage cavity 50, thereby realizing the connection between the storage cavity 50 and the air duct 13.

[0037] Furthermore, the storage cavity 50 has an opening 51, and the opening 51 is used for placing items in the storage cavity 50, and the belt body 20 can open and close the opening 51. In this embodiment, the storage cavity 50 is arranged at the lower position of the shell 10, and the opening 51 is arranged at the bottom of the shell 10. The belt body 20 is detachably connected to the shell 10, and the belt body 20 can open / close the opening in response to being connected or disassembled from the shell 10. That is, the belt body 20 closes the opening 51 while being detachably connected to the shell 10. Under this structure, there is no need to set a separate cover to close the opening 51, which simplifies the structure, makes the overall structure more compact, and reduces the manufacturing cost. In addition, after the belt body 20 is damaged, the belt body 20 can be replaced separately to extend the service life of the entire multifunctional wrist fan.

[0038] See also Figure 2 The belt body 20 is detachably connected to the housing 10 through a connecting piece 60. The housing 10 is provided with a first through hole 62 for the connecting piece 60 to pass through, and the belt body 20 is provided with a second through hole 64 for the connecting piece 60 to pass through.
