DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0038] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0039] Example 1

[0040] like Figure 1-6 As shown, a mobile phone fan includes a fan body 100, a base 300 and a support frame 200 suitable for connecting the fan body 100 and the base 300. The fan body 100 includes a shell and a fan 101 built into the shell. The shell is formed with an air inlet end 104 and an air outlet end 105. The air outlet end 105 is arranged toward the front of the mobile phone. The fan 101 is suitable for driving the air flow from the air inlet end 104 to the air outlet end 105. The base 300 includes a mounting portion 301, which is a circular ring with a built-in magnet 304. The mounting portion 301 is assembled to the back shell of the mobile phone by magnetic attraction. In some other embodiments, the mounting portion 301 can also be assembled to the back shell of the mobile phone by clamping, wrapping or gluing. The support frame 200 enables the fan body 100 to extend out of the edge of the mobile phone and deliver air toward the human body.

[0041] In this embodiment, the support frame 200 is a foldable structure comprising a pivotally connected first bracket 201 and a second bracket 202. The first bracket 201 is pivotally connected to the housing via a hinge assembly, and the second bracket 202 slides along the length of the base 300 to adjust the extension distance of the fan body 100. In some other embodiments, the second bracket 202 is pivotally connected to the base 300, or the second bracket 202 is a retractable structure, wherein the second bracket 202 and the base 300 are relatively fixedly connected. All of these designs can adjust the extension height of the fan body 100.

[0042] In the unfolded state, the air outlet 105 can be flipped to face the front of the phone for cooling the body. In the folded state, the fan body 100 can be flipped to face the base 300. In some other embodiments, the first bracket 201 and the second bracket 202 do not overlap in the folded state, which can achieve a more compact and thin folded state.

[0043] In this embodiment, the hinge assembly includes a first rotating shaft 203 and a damping device 204 mounted on the first rotating shaft 203. The damping device 204 is fixedly mounted on the first rotating shaft 203 and is in sliding contact with the shell to provide damping, so as to achieve hovering relative to the first bracket 201 and thereby adjust the setting angle of the fan body 100.

[0044] In this embodiment, the base 300 includes a sliding area 302, which is a sliding groove structure suitable for accommodating the second bracket 202. The side of the second bracket 202 is telescopically aligned with the sliding area 302. Specifically, the base 300 is arranged parallel to and closely adjacent to the back of the mobile phone. The sliding groove structure and the second bracket 202 slide in a direction parallel to the mobile phone to directly adjust the height of the fan body 100, allowing the user to directly observe and experience the adjustment effect. Furthermore, the second bracket 202 is adapted to be positioned relative to the base 300 via a second positioning device. The second positioning device includes a second contact 205 disposed on the second bracket 202. The base 300 includes a plurality of second positioning slots 303 arranged along the sliding direction. The second contact 205 can selectively engage one of the second positioning slots 303 to position the second bracket 202.

[0045] In this embodiment, the shell includes an inner shell 102 and an outer shell 103 that are coaxially arranged. The inner shell 102 is suitable for accommodating the fan 101 and is suitable for forming an air inlet end 104 and an air outlet end 105. An electromechanical cavity 108 is formed between the inner shell 102 and the outer shell 103. The electromechanical cavity 108 has a built-in battery 107 suitable for the function of the fan 101 and a control circuit board 106 suitable for regulating the opening and closing and power of the fan 101. The fan body 100 is independently powered by the battery 107 to reduce the battery life pressure of the mobile phone, especially in hot outdoor environments. Adding a power bank is even more burdensome.

[0046] Example 2

[0047] A mobile phone fan differs from Example 1 in that the support frame 200 is a retractable structure comprising a telescopic rod. The telescopic rod comprises a starting unit rod and a terminal unit rod. The starting unit rod is pivotally connected to the fan body 100 via a hinge assembly, while the terminal unit rod is fixedly connected to the base 300. When the telescopic rod is stowed, it creates a compact structure, providing a more comfortable user experience. Furthermore, the telescopic rod has a rectangular cross-section, providing excellent support for the fan body 100 and a more uniform overall structure.

[0048] In some other embodiments, the support frame 200 includes a plurality of parallel telescopic rods, wherein the plurality of starting unit rods are pivotally connected to the fan body 100 on the same axis. The terminal unit rods can also be pivotally connected to the base 300 and slidably engaged to obtain a larger adjustment range.

[0049] In this embodiment, the fan body 100 is adapted to be suspended relative to the support frame 200 by a first positioning device to adjust the setting angle of the fan body 100. The first positioning device includes a first positioning contact and a plurality of circumferentially distributed first positioning slots. The first positioning contact rotates synchronously with the fan body 100 about the first rotating shaft 203, while the first positioning slot remains relatively fixed relative to the first positioning slot. The first positioning contact can selectively engage one of the first positioning slots to achieve positioning of the fan body 100.

[0050] In this embodiment, the base body 300 includes a mounting portion 301 and a rotating portion. The mounting portion 301 is a circular ring with a built-in magnet 304. The mounting portion 301 includes an inner periphery arranged on the mounting portion 301. The rotating groove is annular or arc-shaped. The central angle corresponding to the rotating groove is 270°. The rotating portion includes a rotating block arranged on the outer periphery of the rotating portion. The rotating block is suitable for extending into the rotating groove and slidingly cooperating with it. The rotating portion thereby drives the fan body 100 to rotate 270° through the support frame 200.

[0051] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
