The motor and / or motor bracket of the fan body 3 are fixed at the fan body fixing seat 14 of the first housing 1. Specifically, the fixing can be achieved by screws or buckles.

[0028] Please refer to the following: Figure 2 and Figure 3 The first connecting rib 12 of the first outer shell 1 and the second connecting rib 22 of the second outer shell 2 are detachably fixed to each other after passing through the mounting hole 10a of the sheet 10.

[0029] The first fixed edge 11 of the first outer shell 1 and the second fixed edge 21 of the second outer shell 2 are capable of clamping the sheet 10 from both sides of the sheet 10 respectively.

[0030] Please refer to the following: Figure 2 -and Figure 4 In this embodiment, the first connecting rib 12 of the first outer shell 1 is provided with a first thread 12a, which is integrally formed with the first connecting rib 12; the second connecting rib 22 of the second outer shell 2 is provided with a second thread 22a, which is integrally formed with the second connecting rib 22; the first connecting rib 12 of the first outer shell 1 and the second connecting rib 22 of the second outer shell 2 are screwed together, so that the first connecting rib 12 of the first outer shell 1 and the second connecting rib 22 of the second outer shell 2 can be detachably fixed to each other.

[0031] In some other possible embodiments, a first fastening structure (e.g., a snap-fit ​​claw integrally formed on the first connecting rib 12) is provided at the first connecting rib 12 of the first housing 1; a second fastening structure (e.g., a snap-fit ​​groove integrally formed on the second connecting rib 22) is provided at the second connecting rib 22 of the second housing 2; the first connecting rib 12 of the first housing 1 and the second connecting rib 22 of the second housing 2 fasten to each other, and in this way, the first connecting rib 12 of the first housing 1 and the second connecting rib 22 of the second housing 2 can also be detachably fixed to each other.

[0032] Furthermore, a friction-enhancing structure 20 suitable for contacting the sheet 10 is provided at the first fixed edge 11 of the first housing 1 and / or the second fixed edge 21 of the second housing 2.

[0033] More specifically, the friction-enhancing structure 20 is a structure that protrudes / recesses relative to the surface of the first fixed edge 11 of the first housing 1 and / or the second fixed edge 21 of the second housing 2.

[0034] Please refer to the following: Figure 4 In this embodiment, the friction enhancement structure 20 is a rib-shaped protrusion structure integrally formed on the surface of the first fixed edge 11 of the first housing 1; in other possible embodiments, the friction enhancement structure 20 may also be a rib-shaped protrusion structure, a groove-shaped recessed structure, or a friction texture structure (e.g., a mesh texture or a frosted texture) integrally formed on the surface of the first fixed edge 11 of the first housing 1 and / or the second fixed edge 21 of the second housing 2.

[0035] In this embodiment, the fan module is used by unscrewing the first outer shell 1 and the second outer shell 2. The first connecting rib 12 of the first outer shell 1 and the second connecting rib 22 of the second outer shell 2 are then passed through the mounting holes 10a of the sheet 10. Using the first thread 12a of the first connecting rib 12 and the second thread 22a of the second connecting rib 22, the first connecting rib 12 of the first outer shell 1 and the second connecting rib 22 of the second connecting rib 22 are screwed together, thereby fixing the first outer shell 1 and the second outer shell 2 as a single unit. At this time, the first fixing edge 11 of the first outer shell 1 and the second fixing edge 21 of the second outer shell 2 can be opened from both ends of the sheet 10. The sheet 10 is clamped on both sides. At the same time, the friction enhancement structure 20 at the first fixed edge 11 of the first shell 1 and / or the second fixed edge 21 of the second shell 2 can enhance the friction between the first fixed edge 11 of the first shell 1 and / or the second fixed edge 21 of the second shell 2 and the sheet 10. In this way, without the need for fixing methods such as adhesive, buckles, screw-nut locking or sewing, and without setting any fixing structure on the sheet 10, the fan module can be stably fixed on the sheet 10, thereby providing inflation or ventilation function for daily necessities made from the sheet 10.

[0036] When the fan module of this embodiment is disassembled relative to the sheet 10, it can be easily disassembled by simply unscrewing the first outer shell 1 and the second outer shell 2, which is simple, efficient and quick.

[0037] In this embodiment, the first connecting rib 12 of the first outer shell 1 and the second connecting rib 22 of the second outer shell 2 pass through the mounting hole 10a of the sheet 10 and are detachably fixed to each other. The first fixing edge 11 of the first outer shell 1 and the second fixing edge 21 of the second outer shell 2 can clamp the sheet 10 from both sides. Without the need for adhesive, clips, screw-nut locking or sewing, and without setting any fixing structure at the sheet 10, the fan module can be stably fixed at the sheet 10, thereby providing inflation or ventilation functions for daily necessities made of the sheet 10. The fan module can be easily, efficiently and quickly disassembled by simply unscrewing the first outer shell 1 and the second outer shell 2, which improves the user experience of daily necessities made of sheet 10 (such as cloth, mesh, fiber, non-woven fabric and composite materials, etc.), such as tents, inflatable dolls, cartoon costumes, mosquito nets and ventilated mattresses.
