[0035] Example 1

[0036] like Figures 1-4 The mobile phone fan includes a base 100, a fan body 200, and a folding unit 300. The base 100 includes a fixed seat 101 and a rotating seat 102 that rotates relative to the fixed seat 101. The fixed seat 101 is magnetically attached to the back cover of the mobile phone. Specifically, the fixed seat 101 has a built-in annular magnet 103.

[0037] The fan body 200 includes a cylindrical outer shell 201, a cylindrical inner shell 202, and a fan 203 built into the inner shell 202. The inner shell 202 has an air inlet 207 and an air outlet 208 formed at both axial ends. An electromechanical cavity 204 is defined between the inner shell 202 and the outer shell 201. The electromechanical cavity 204 houses a battery 205 suitable for functioning the fan 203 and a control circuit board 206 suitable for regulating the fan 203's on / off state and power. The outer shell 201 includes a strip-shaped stop portion 209 arranged along its axial direction. A limit plate 210 extends from the end of the stop portion 209 near the air outlet 208, and the end of the stop portion 209 near the air inlet 207 is pivotally connected to the folding unit 300. Furthermore, the battery 205 is positioned adjacent to the stop portion 209, thereby lowering the center of gravity of the fan body 200 and facilitating stability. The folding unit 300 includes a first folding part 301 and an extension part 302. The first folding part 301 is pivotally connected to the extension part 302 and the fan body 200 respectively. The rotating seat 102 forms an adjustment groove 104. The extension part 302 is telescopically accommodated in the adjustment groove 104. The base 100, the folding unit 300 and the fan body 200 form a Z-shaped folding structure.

[0038] In this embodiment, the adjustment groove 104 includes a plurality of positioning grooves 105 arranged along the extension direction of the extension 302. Positioning protrusions 303 are provided on both sides of the extension 302 near the bottom end. The positioning protrusions 303 engage with one of the positioning grooves 105 to restrict the movement of the extension 302 and achieve positioning.

[0039] The edges of a mobile phone include the long axis edge and the short axis edge. The long axis edge can also be referred to as the top and bottom edges when the phone is held vertically, and the short axis edge can also be referred to as the left and right edges when the phone is held vertically.

[0040] In this embodiment, in the folded state, the extension portion 302 extends at least partially out of the positioning groove 105, the first folded portion 301 flips over to overlap the extension portion 302, and the air inlet end 207 is in contact with the rotating seat. The folding unit 300 extends partially out of the short axis edge, and the rotating seat 102 can drive the folding unit 300 to rotate to be set parallel to the short axis edge, so that the mobile phone can completely cover the fan body 200 and the folding unit 300.

[0041] In this embodiment, the process of changing from a folded state to an unfolded state is as follows: First, if the phone is placed horizontally, rotate the rotating base 102 so that the adjustment slot 104 changes from being parallel to the edge of the short axis to being perpendicular to the edge of the short axis; if the phone is placed vertically, there is no need to rotate the rotating base 102. Simply pull the extension 302 completely out of the adjustment slot 104. Second, adjust the extension length of the extension 302 and flip the first fold 301 so that the air outlet 208 faces the front of the phone. Furthermore, a damping element is provided between the fan body 200 and the first fold 301 to allow the fan body 200 to hover at any angle, making it convenient for the user to adjust the air delivery angle.

[0042] Further adjustments, such that the short or long axis edge is suitable for supporting the stop portion 209, can provide two-point support for the fan body 200, resulting in better stability and mitigating vibrations caused by the operation of the fan 203. Adjusting the fan body 200 to be perpendicular to the phone and moving it backwards allows the limiting plate 210 to work with the phone to limit the fan body 200 along its axial direction, while also minimizing the interference of the fan body 200 on the user's line of sight.

[0043] Example 2

[0044] A mobile phone fan, compared to embodiment 1, differs in that the folding unit 300 includes a first folding portion 301 adapted to pivotally connect to the fan body 200 and a second folding portion adapted to rotatably connect to the base 100. The extension length of the folding unit 300 is adjusted by adjusting the folding angle between the first folding portion 301 and the second folding portion. Specifically, when the first folding portion 301 and the second folding portion are unfolded, the fan body 200 is adapted to extend beyond the long axis edge of the mobile phone; when the first folding portion 301 and the second folding portion overlap, the fan body 200 is adapted to extend beyond the short axis edge of the mobile phone.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
