The present disclosure relates to the technical field of fans, and in particular, to a folding rotatable handheld fan.
A handheld fan is a handheld cooling product. It is loved by the great majority of consumers due to its portability.
In the related technology, a folding rotatable handheld fan mainly includes a hand grip, a rotating handle, and a fan assembly. An end portion of the rotating handle is connected to an end portion of the hand grip through a rotating shaft. The fan assembly is mounted at an end portion of the rotating handle away from the rotating shaft. Turning the rotating handle around an axial line of the rotating shaft can fold the handheld fan to shorten the handheld fan. In order to inform a user of a gear and battery level of the handheld fan, a display module will be arranged on a surface of the hand grip. The display module is connected to a battery inside the rotating handle through a wire passing through the rotating shaft.
Regarding the above-mentioned related technology, when the handheld fan is used, the rotating handle is rotated around the axial line of the rotating shaft and drives the rotating shaft to rotate. During multiple rotations of the rotating handle, the wire between the display module and the battery will be worn out. Meanwhile, due to the non-directional rotation of the rotating handle, the wire for connecting the display module to the battery will be entangled together. Over time, the wire will pull welding points on the display module and the battery, and the wire at the welding points falls off. As a result, the handheld fan fails to be used and needs to be disassembled for repair. This shortens the service life of the handheld fan.
In order to prolonging the service life of the handheld fan, the present application provides a folding rotatable handheld fan.

The display module 6 is arranged in the rotating handle 2, so that the display module 6 and the battery 4 are located in the same shell, and the display 62 is arranged in the rotating ring 5. When the rotating handle 2 is driven to rotate, the rotating handle 2 drives the display module 6 to rotate. Meanwhile, the rotating handle 2 drives the rotating ring 5 to rotate, so as not to cause wire wear and entanglement, which is conducive to prolonging the service life of the handheld fan. Moreover, when the handheld fan is used, a gear and battery level of the handheld fan can be observed through the display 62 arranged inside the rotating ring 5.

When the rotating handle 2 needs to be stored, the rotating handle 2 is rotated, so that the rotating handle 2 enters a space between the first baffle plate 11 and the second baffle plate 12, and the hand grip 1 stores the rotating handle 2. When the fan needs to be used, the rotating handle 2 is rotated 180° around an axial line of the rotating ring 5. The rotating handle 2 is rotated out of the hand grip 1 to use the fan. The hand grip 1 and the rotating handle 2 are rotated to be folded, making the fan have a smaller volume and easier to carry. The hand grip 1 also provides protection for the fan and the rotating handle 2.
The rotating handle 2 includes an upper shell 21 and a lower shell 22. The upper shell 21 and the lower shell 22 are clamped by buckles. The fan assembly 3 includes a brush motor 31, a mounting assembly 32, and a fan blade 33. The mounting assembly 32 includes a mounting plate 321 and a limiting plate 322. The brush motor 31 is mounted in the upper shell 21 and the lower shell 22. The brush motor 31 is located at one end of the upper shell 21 close to the support plate 111 and one end of the lower shell 22 close to the support plate 111. An output shaft of the brush motor 31 faces the upper shell 21 and extends out of the upper shell 21. A middle position of a side surface of the mounting plate 321 is connected with a connecting rod 323. The output shaft of the brush motor 31 is plugged into the connecting rod 323 from an end surface of the connecting rod 323. The output shaft of the brush motor 31 is in interference with the connecting rod 323. The side surface of the mounting plate 321 close to the connecting rod 323 is connected with two mounting columns 324. A side surface of the limiting plate 322 is provided with two limiting slots 3221 for plugging the two mounting columns 324.

The two rotating blocks 331 sleeve circumferential surfaces of the two mounting columns 324, and the fan blades 33 are located between the second baffle plate 12 and the upper shell 21.
When the fan is used, the motor 31 drives the mounting plate 321 to rotate, and the mounting plate 321 drives the limiting plate 322 and the fan blade 33 to rotate together. The fan blades 33 are gradually unfolded under the action of a centrifugal force, which can induce an air flow. When the fan is stored, the fan blades 33 rotate around the mounting columns 324 under the own gravity, and the two fan blades 33 are gathered together and are stored between the second baffle plate 12 and the upper shell 21.
The side surface of the second baffle plate 12 close to the first baffle plate 11 is provided with a positioning plate 122; a plurality of arc-shaped positioning slots 1221 are arranged at an end portion of the positioning plate 122 away from the second baffle plate 12; and a side edge of the fan blade 33 is clamped in the positioning slots 1221. When the fan blade 33 is stored between the second baffle plate 12 and the upper shell 21, as the fan blade 33 is a twisted blade, the side edge of the fan blade 33 is clamped in the positioning slots 1221. The positioning slots 1221 fix the fan blade 33, making it difficult for the fan blade 33 to run out of the space between the second baffle plate 12 and the upper shell 21 when a user carries the fan, thus protecting the fan blade 33.
