[0040] like Figure 1-6The multifunctional mobile phone fan comprises a fan body 100, a seat body 300 and a folding bracket 200 suitable for connecting the fan body 100 and the seat body 300. The fan body 100 comprises a housing and a fan 101, the fan 101 is an axial flow fan, the housing comprises an inner housing 102 and an outer housing 103, the inner housing 102 and the outer housing 103 are coaxially sleeved, the inner housing 102 is suitable for accommodating the fan 101 and forming an air inlet end 104 and an air outlet end 105 at two axial ends, and the fan 101 is suitable for driving the airflow from the air inlet end 104 to the air outlet end 105. The inner shell 102 and the outer shell 103 enclose a first cavity 106 and a second cavity 107 disposed on the periphery of the air outlet end 105. The first cavity 106 is suitable for accommodating a control circuit board 112 and a battery 113. The second cavity 107 is suitable for accommodating a fill light. The battery 113 is suitable for powering the fan 101 and the fill light. The control circuit board 112 is suitable for controlling the fan 101 and the fill light to start and stop independently. The folding bracket 200 includes a first bracket 201 and a second bracket 202. The first bracket 201 is hinged to the outer shell 103 and the second bracket 202, respectively. The base body 300 includes a fixed part 301, a rotating part 302 and a sliding part 303. The fixed part 301 is in a circular ring shape and has a built-in annular magnet 305, which can be magnetically attracted to the back shell of the mobile phone. The rotating part 302 rotates with the fixed part 301. The sliding part 303 is relatively fixedly arranged on the rotating part 302. The sliding part 303 includes a sliding groove 304 arranged along its length direction. The second bracket 202 can be telescopically accommodated in the sliding groove 304.

The control circuit board 112 and the battery 113 are symmetrically arranged on the upper and lower sides of the inner shell 102. This design is conducive to making full use of the first cavity 106, with a compact structure and balanced counterweight. Furthermore, the battery 113 is arranged below the inner shell 102, and the battery 113 is centered in the first cavity 106. This design can lower the center of gravity of the fan body 100 and when holding the mobile phone, and keep the center of gravity at or close to the middle area, thereby improving the user experience. The fan body 100 rotates at least 180° to switch between the unfolded state and the folded state.

[0045] In this embodiment, the sliding part 303 is arranged along the radial direction of the fixed part 301, and the sliding part 303 is provided with a guide groove 306 facing the back shell of the mobile phone. The sliding part 303 and the rotating part 302 are enclosed to form a vent 307 suitable for connecting the guide groove 306, and the vent 307 is arranged on both sides of the sliding part 303. When the fixed part 301 is magnetically attracted to the back shell of the mobile phone, the adsorption surface of the fixed part 301 and the back shell of the mobile phone does not have sealing performance. In some other embodiments, the fixed part 301 has a notch suitable for connecting the guide groove 306. In the folded state, the air inlet end 104 is flipped to cover the vent 307, and the fan 101 is suitable for driving the airflow through the guide groove 306 and taking away the heat of the back shell of the mobile phone, and then entering the air inlet end 104 through the vent 307, effectively reducing the temperature of the back shell of the mobile phone and improving the user experience.

[0046] In some other embodiments, the fan 101 is a centrifugal fan 101, the inner shell 102 is suitable for forming an air inlet end 104 and an air outlet end 105 that are perpendicular to each other, the outer shell 103 is suitable for exposing the air outlet end 105, the control circuit board 112 is arranged above the inner shell 102, the battery 113 is arranged above the inner shell 102 or at one end of the inner shell 102 away from the air outlet, and the fan body 100 rotates at least 90° to switch between the unfolded state and the folded state.

[0047] In this embodiment, one end of the first bracket 201 is pivoted to the outer shell 103 through a first hinge assembly, the first hinge assembly includes a first rotating shaft 203 and a first damping member 204 sleeved on the first rotating shaft 203, and the first damping member 204 is suitable for providing damping to enable the fan body 100 to hover relative to the first bracket 201. The other end of the first bracket 201 is pivoted to the second bracket 202 through a second hinge assembly, the second hinge assembly includes a second hinge shaft 205 and a second damping member 206, and the second damping member 206 is suitable for providing damping to enable the fan body 100 to hover relative to the first bracket 201. The first rotating shaft 203 and the second rotating shaft are both arranged parallel to the mobile phone. Through the design of the hinge assembly and the damping member, the user can easily adjust the position of the fan body 100 to achieve hovering, and the operation is simple.

[0048] In this embodiment, the outer shell 103 includes a strip-shaped stop portion 108 arranged along its axial direction, and a limit plate 109 extends from one end of the stop portion 108 close to the air outlet, and one end of the stop portion 108 close to the air inlet is pivotally connected to the folding bracket 200. Furthermore, the battery 113 is arranged adjacent to the stop portion 108, thereby lowering the center of gravity of the fan body, which is conducive to maintaining stability. If further adjustment is made so that the short axis edge or the long axis edge is suitable for supporting the stop portion 108, a two-point support can be formed for the fan body, and the support stability is better, which can alleviate the vibration caused by the operation of the fan 101. If the fan body is adjusted to be perpendicular to the mobile phone, and the fan body is moved backward so that the limit plate 109 can cooperate with the mobile phone to limit the fan body along its axial direction, it also minimizes the interference of the fan body on the user's line of sight.

[0049] In this embodiment, the second cavity 107 of the folding bracket 200 includes a circular light-transmitting cover plate 111, and the fill light includes an LED lamp bead group 110 that matches the shape of the light-transmitting cover plate 111. The ring-shaped LED lamp bead group 110 can provide uniform and soft lighting, so that a more natural and bright skin color can be obtained when taking selfies, and can expand the fill light range and reduce the shadow of the face, so that the photographed effect is clearer and more three-dimensional. The LED lamp bead group 110 includes a plurality of unit lamp beads, and the control circuit board 112 includes a PWM module, which is suitable for adjusting the light emission ratio of the unit lamp beads and then adjusting the brightness of the LED lamp bead group 110.
