The connecting groove 32 is recessed from the inner side surface 240 of the second body 20 toward the outer side surface 241, and does not penetrate through the outer side surface 241, and when the first body 10 is connected to the second body 20, the outer side surface 241 of the first body 10 is flush with the outer side surface 241 of the second body 20. The depth of the connecting groove 32 from the inner side 240 to the outer side 241 of the second body 20 is less than the thickness of the second body 20, and when the first body 10 is connected with the second body 20, the outer side 241 of the first body 10 is flush with the outer side 241 of the second body 20, so that the outer side 241 of the neck hanging fan is smooth and flat, and the appearance is improved; next, the rotational direction of the first body 10 with respect to the second body 20 can be restricted, and the stability of the first body 10 and the second body 20 after switching from the folded state to the unfolded state in use can be ensured.

Optionally, the groove 312 and the positioning bead 311 are respectively disposed on two opposite side surfaces of the connecting portion 31, and extension lines of connecting lines of the positioning bead 311 intersect with the top surface 243 and the bottom surface 244 respectively. The positioning beads 311 are respectively disposed on two opposite side surfaces of the connecting portion 31 parallel to the top surface 243 and the bottom surface 244, so that when the first body 10 and the second body 20 rotate relative to each other with the positioning beads 311 as an origin, the rotation direction is limited to only include a direction toward the inner side surface 240 of the first body 10 and a direction away from the inner side surface 240 of the first body 10, a folded state is formed in which the second body 20 rotates and folds toward the inner side surface 240 of the first body 10 relative to the first body 10, and the second body 20 rotates from the folded state toward the direction away from the inner side surface 240 relative to the first body 10 until the outer side surfaces 241 of the first body 10 and the second body 20 keep a parallel unfolded state.

In some embodiments, an elastic member is disposed between the positioning ball 311 and the surface surrounding the groove 312, and the elastic member naturally exerts an abutting force on the positioning ball 311, so that the positioning ball 311 partially protrudes out of the groove 312. The two ends of the elastic element are respectively connected with the positioning ball 311 and the surface surrounding the groove 312, and through the arrangement of the elastic element, when the positioning ball 311 is not subjected to external extrusion acting force, the positioning ball 311 partially protrudes out of the groove 312 under the action of the elastic element; when the first body 10 and the second body 20 are connected, in the process that the connecting portion 31 is inserted into the connecting groove 32, the portion of the positioning bead 311 protruding out of the groove 312 is pressed by the surface surrounding the connecting groove 32, the elastic member is compressed, the positioning bead 311 is accommodated in the groove 312, when the connecting portion 31 moves in the connecting groove 32 until the positioning bead 311 aligns with the positioning groove 320, the positioning bead 311 is no longer pressed by the surface surrounding the connecting groove 32, the elastic member recovers from the compressed state and deforms to abut against the positioning bead 311 to protrude out of the groove 312 again, at this time, the positioning bead 311 protruding out of the groove 312 is accommodated in the positioning groove 320, and the purpose of connecting the first body 10 and the second body 20 is achieved. On the contrary, when the first body 10 and the second body 20 need to be detached from each other, only the first body 10 and the second body 20 need to be held to apply force in the direction away from each other, so that the positioning beads 311 slide out of the corresponding positioning grooves 320, and after the positioning beads 311 slide out of the positioning grooves 320, the positioning beads 311 are squeezed by the surface enclosing the connecting groove 32 to squeeze the elastic member, so that the elastic member is compressed, and the positioning beads 311 are accommodated in the grooves 312, until the connecting portion 31 is separated from the connecting groove 32, and the elastic member is restored from the compressed state to be deformed and restored to the state before the second body 20 is disconnected from the first body 10. Alternatively, the elastic member may be a spring.

In some embodiments, a recessed portion 25 is disposed on the outer side surface 241 of the second body 20 along the length direction thereof, an air inlet 22 corresponding to the position of the fan 41 and a cover plate 26 covering the recessed portion 25 are disposed in the recessed portion 25, a gap is formed between the cover plate 26 and the surface of the second body 20 forming the recessed portion 25, and the air inlet 22 is communicated with the external environment through the gap. The concave portion 25 is communicated with the air inlet 22, and the cover plate 26 is arranged to prevent dust and other impurities from entering the interior of the neck hanging fan from the air inlet 22, so that the service life of the fan 41 is affected, and the hair of a user can be prevented from being hinged into the air inlet 22 in a wearing state, so that the use experience of the user is affected. Due to the arrangement of the concave portion 25, air in the external environment can be firstly stored in the concave portion 25 through the gap and then enters the second body 20 from the air inlet 22, so that the air inlet speed of the air inlet 22 is increased.
