[0042] It can be understood that, through the opening 1111, the connecting member 113 and the support rod 12 can be rotated relative to the fan assembly 112, thereby adjusting the state of the fan 1, facilitating the storage and use of the fan 1, and improving the user experience. Specifically, the connecting member 113 and the support rod 12 can be rotated relative to the fan housing 111 and the fan assembly 112, so that the connecting member 113 can switch between a first state and a second state. In the first state, the rotation axis direction of the fan assembly 112 is the same as the support direction of the support rod 12, so that the fan 1 is in the third storage state. In the second state, the rotation axis direction of the fan assembly 112 is perpendicular to the support direction of the support rod 12, so that the fan 1 is in the third support state.

[0043] In this embodiment, the second base plate 1113 has an air outlet 1113a, and the first side wall structure 1114 has a plurality of air inlets 1114a; the fan assembly 112 includes an air guide shell 1121 and a fan blade structure 1122 located in the air guide shell 1121, and a driving structure 1123 connected to the fan blade structure 1122; the fan 1 also includes a light source 115 arranged on the second base plate 1113, and a light source cover 116 arranged around the light source 115 and connected to the second base plate 1113; the air outlet 1113a is a plurality of air outlets 1113a arranged around the light source 115; the fan 1 also includes a focusing bracket 117 installed on the second base plate 1113, The focusing bracket 117 has a avoidance opening 1171 and a plurality of ventilation openings 1172 arranged around the avoidance opening 1171, the avoidance opening 1171 corresponds to the light source cover 116, and the ventilation openings 1172 correspond to the air outlet 1113a. The focusing bracket 117 is used to adjust the distance between the light source cover 116 and the light source 115 for focusing, and the light source cover 116 is a convex lens; the fan housing 111 also includes a movable plate 1115, which is movably connected to the first side wall structure 1114, and the movable plate 1115 can switch between a shielding state of shielding the second opening 1111b and an opening state of opening the second opening 1111b.

[0044] By providing the air inlet 1114a, the air outlet 1113a and the drive structure 1123, the overall structural design of the fan assembly 112 is reasonable and compact, which can achieve good wind efficiency without affecting the state switching of the fan 1. By providing the light source 115 and the light source cover 116, the fan 1 also has a lighting effect, which provides a better user experience. Through the focusing bracket 117, the distance between the light source cover 116 and the light source 115 can be adjusted to achieve different lighting effects, further improving the user experience.

The slide groove 131 is located inside the base 13, and the end of the second side wall structure 133 close to the fourth bottom plate 132 has a notch 1321 corresponding to the supporting foot 14 and connected to the slide groove 131. The supporting foot 14 can extend from the notch 1321 to be in the first supporting state, and in the first storage state, at least a portion of the supporting foot 14 is located in the notch 1321.

[0052] It can be understood that in the first storage state, at least part of the support foot 14 is located in the notch 1321, and the outer surface of the support foot 14 located in the notch 1321 and the outer surface of the second side wall structure 133 can be flush and smoothly transitioned, thereby achieving a better storage effect, improving the aesthetics of the storage state, and also helping to reduce the volume of the storage state and improve portability.

[0053] In this embodiment, the cross-sectional shape and size of the first side wall structure 1114 of the fan housing 111 are consistent with the cross-sectional shape and size of the second side wall structure 133 of the base 13, so that the base 13 and the fan housing 111 can be overlapped and in a folded state; the cross-sectional shape of the first side wall structure 1114 of the fan housing 111 and the cross-sectional shape of the second side wall structure 133 of the base 13 are both circular, so that the fan 1 is cylindrical when in the folded state.

[0054] It can be understood that through the design of the above structure, the fan 1 is cylindrical when in the folded state, which further achieves a better storage effect, improves the aesthetics of the stored state, and is also conducive to reducing the volume of the stored state and improving portability.

[0055] In this embodiment, the fan 1 also includes a wire 18, and the fan 1 also includes a battery 19 arranged in the base 13. The wire 18 passes through the interior of the support rod 12, and one end of the wire 18 is electrically connected to the fan head 11, and the other end of the wire 18 is electrically connected to the battery 19; the number of the batteries 19 corresponds to the support legs 14, and one battery 19 is arranged between two adjacent support legs 14.

[0056] By installing a battery 19 in the base 13, and allowing for multiple batteries 19, not only does it facilitate unplugged use and improve battery life, but the batteries 19 also increase the weight of the base 13, improving its support stability. Furthermore, the number of batteries 19 corresponds to the number of support legs 14, with one battery 19 installed between two adjacent support legs 14. This also makes the internal components of the base 13 reasonably compact, better balanced, and more stable.
