The charging and discharging module 3 is disposed in the handle housing 2 to supply power to the handheld air blowing device, thereby meeting the need for using the handheld air blowing device anytime and anywhere in an outdoor or mobile scenario, and exhibiting high portability.

Specifically, in this embodiment, as shown in FIGS. 1 and 2, the fan main body 1 has a tubular structure, and an air blowing assembly 13 is mounted in the fan main body 1. The air blowing assembly 13 is capable of generating an air flow when connected to a power source, thereby achieving the fan function. The bottom of the fan main body 1 is provided with a recessed mounting groove 11, the recessed mounting groove 11 has a closed frame shape, and the recessed mounting groove 11 is configured to match the handle housing 2 for mounting. More specifically, in this embodiment, the handle housing 2 has a columnar hollow cavity structure with an open upper end, and a shape of the opening matches a shape of the recessed mounting groove 11. The upper end of the handle housing 2 is inserted into the recessed mounting groove 11, and the handle housing 2 and the fan main body 1 are fastened and mounted together through connectors, thereby forming an overall structure of the fan. To connect the handle housing 2 and the fan main body 1, two sets of first connecting holes 12 are arranged symmetrically in the inner sides of the recessed mounting groove 11 along the longitudinal direction of the fan main body 1, and each set includes two holes. Correspondingly, two sets of second connecting holes 21 corresponding to first connecting holes 12 are arranged symmetrically on the upper end of the handle housing 2 on both sides, and each set includes two holes. The connectors are conventional self-tapping screws. After the handle housing 2 is inserted into the recessed mounting groove 11, the connectors pass through the second connecting holes 21 and are fastened and mounted to the first connecting holes 12, such that the handle housing 2 is securely mounted onto the fan main body 1 to form a complete fan. It should be noted that in some embodiments, dot-shaped protrusions (not shown) may be configured at positions of the second connecting holes 21. When the handle housing 2 is inserted into the recessed mounting groove 11, the dot-shaped protrusions directly snap into the first connecting holes 12, thereby facilitating disassembly and assembly of the handle housing 2 and the fan main body 1. The disassembled handle housing 2 and fan main body 1 are only connected by a wire, which helps improve the portability and storage of the air blowing device.
