[0002] With the widespread use of portable electronic devices such as smartphones, the problem of mobile phone heating is becoming increasingly serious as processor performance continues to improve and user usage time increases. Traditional heat dissipation methods such as metal back shells and graphite heat dissipation films cannot meet the heat dissipation requirements brought by high-performance processors. Especially when used for a long time or running large applications, the problem of mobile phone heating is particularly prominent. Although existing portable fan products can cool the human body, they cannot directly dissipate heat from the mobile phone, and are inconvenient to carry, making them unsuitable for long-term outdoor or mobile use scenarios. Most existing heat dissipation products or portable fans can only meet a single heat dissipation requirement and cannot be adjusted according to the specific needs of users, lacking flexibility.

DETAILED DESCRIPTION

[0026] 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.

[0027] 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.

[0028] 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.

[0029] like Figure 1-4A mobile phone fan includes a fan body 100, a base 200, and a folding bracket 300. The folding bracket 300 is suitable for connecting the base 200 and the fan body 100 to form a foldable structure. The fan body 100 includes a housing 101, an axial flow fan 102 built into the housing 101, and an air inlet 103 and an air outlet 104 arranged at both axial ends of the housing 101. The base 200 includes a mounting component, which includes a mounting ring 201 with a built-in magnetic body 202 and a flow guide component 203 arranged radially along the mounting ring 201. The mounting component is assembled to the back shell of the mobile phone by magnetic attraction. The flow guide component 203 includes a plurality of flow guide grooves 204 arranged facing the back shell of the mobile phone and an adjustment groove 205 arranged along its length. The two sides of the flow guide component 203 and the inner periphery of the mounting ring 201 combine to form two symmetrically arranged ventilation openings 207. More specifically, the guide grooves 204 are evenly arranged in parallel along a direction perpendicular to the guide member 203. The guide grooves 204 include open ports at both longitudinal ends thereof, and the vents 207 are adapted to connect the open ports with the air inlet 103. The folding bracket 300 includes a first folding unit 301 and a second folding unit 302. The second folding unit 302 includes a folding end 305 and a sliding end 306. The first folding unit 301 includes a distal end 303 adapted to pivotally connect to the housing 101 and a proximal end 304 adapted to pivotally connect to the folding section. The second folding unit 302 is retractably accommodated in the adjustment groove 205. Specifically, the sliding end 306 includes a columnar or spherical positioning portion 307. Several positioning grooves 206 are arranged on the inner sidewall of the adjustment groove 205. The sliding end 306 slidably engages with the inner sidewall of the adjustment groove 205, and the positioning portion 307 can selectively engage one of the positioning grooves 206 to achieve positioning.

[0030] In the unfolded state, the air outlet end 104 can be flipped to face the front of the mobile phone to cool the human body. At the same time, the setting height of the fan body 100 can be adjusted by adjusting the extension length of the second folding unit 302 to obtain the optimal air supply height or adapt to different models of mobile phones.

[0031] The process of switching from the unfolded state to the folded state is as follows: first, the second folding unit 302 is extended to the maximum extent, then the proximal end 304 drives the first folding unit 301 to flip backward 90° and overlap with the second folding unit 302, and finally, the fan body 100 flips backward at least 90° relative to the distal end 303 so that the air inlet end 103 contacts the base 200, and the air inlet end 103 completely covers the vent 207.

[0032] In the folded state, the axial flow fan 102 is adapted to drive the airflow continuously through the guide groove 204 into the air inlet end 103 to remove the heat of the mobile phone. At the same time, the fan body 100 can also be supported between the table and the mobile phone to act as a mobile phone holder.

[0033] In this embodiment, the mounting ring 201 is magnetically attached to the back of the phone but not sealed, allowing airflow to flow through the gap between the mounting ring 201 and the back of the phone into the guide groove 204. The mounting ring 201 may also be provided with an air inlet notch, allowing airflow to flow through the air inlet notch into the guide groove 204 and then into the air inlet end 103 through the vent 207.

[0034] In some other embodiments, a plurality of radially arranged guide grooves 204 are evenly disposed on the side of the mounting ring 201 facing the back shell of the mobile phone, and the inner periphery of the mounting ring 201 forms a vent 207 .

[0035] In some other embodiments, the mounting component can be clamped to the edge of the mobile phone by setting a clamping claw, the mounting component can also be set as a mobile phone case structure wrapped around the outside of the mobile phone, or the mounting component can be directly adhered to the back of the mobile phone or the back of the mobile phone case.

[0036] In this embodiment, the distal end 303 is pivotally connected to the end of the shell 101 close to the air inlet end 103 so that the air inlet end 103 can be in full contact with the base 200, and the vent 207 is not blocked by the folding bracket 300, which has a good wind gathering effect and improves the heat dissipation effect.

[0037] In some other embodiments, the fan body 100 includes a housing 101, a centrifugal fan built into the housing 101, an air inlet end 103 and an air outlet end 104 that are perpendicular to each other, and a distal end 303 pivotally connected to the end of the housing 101 near the air supply end. The process of switching from the unfolded state to the folded state is as follows: first, the second folding unit 302 is extended to its maximum extent, then the proximal end 304 drives the first folding unit 301 to flip backward 90° and overlap with the second folding unit 302. The fan body 100 then fully contacts the base 200, with the air inlet end 103 covering the vent 207.

[0038] In other embodiments, the second folding unit 302 is pivotally connected to one end of the air guide member 203. The process of switching from the unfolded state to the folded state is as follows: first, the second folding unit 302 flips to lie flat against the air guide member 203. Then, the proximal portion 304 drives the first folding unit 301 to flip backward 90° so that it overlaps with the second folding unit 302. Finally, the fan body 100 flips backward at least 90° relative to the distal portion 303 so that the air inlet end 103 contacts the base 200 and completely covers the vent 207.

[0039] 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.
