Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] refer to Figure 1 This utility model discloses a magnetic fan 10, which can be attached to external devices to provide localized cooling for users or to assist in the heat dissipation of external devices.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The magnetic fan 10 includes a fan assembly 11, a magnetic base 12, and a support frame 13. The fan assembly 11 includes a housing 111, a fan assembly 112, and a power module 113. The fan assembly 112 and the power module 113 are respectively disposed within the housing 111. The power module 113 supplies power to the fan assembly 112. The housing 111 has a first air inlet 111a and an air outlet 111b, with the air outlet 111b located on the side of the housing 111. The magnetic base 12 is used to magnetically engage with an external device, such as a mobile phone 20, to attach the magnetic fan 10 to the external device. The support frame 13 is connected to the housing 111 and the magnetic base 12. The housing 111 can drive the support frame 13 to rotate relative to the magnetic base 12 in a first direction to change the angle between the fan assembly 11 and the magnetic base 12. The housing 111 can also rotate relative to the support frame 13 in a second direction to change the orientation of the air outlet 111b. In some implementations, the first direction is perpendicular to the second direction.

[0028] The aforementioned magnetic fan 10 includes a magnetic base 12 and a support frame 13. On the one hand, the magnetic fan 10 can be attached to external devices such as mobile phones 20 and tablets through the magnetic base 12 to dissipate heat for the user during the use of these devices. Alternatively, the magnetic fan 10 can be directly supported on a flat surface such as a desk through the magnetic base 12 to expand the usage scenarios. On the other hand, by adjusting the angle between the housing 111 and the support frame 13 and the rotation of the housing 111 relative to the magnetic base 12, the orientation of the air outlet 111b of the housing 111 can be changed more flexibly to facilitate airflow and heat dissipation for the human body, such as the face, thus improving the convenience of use.

[0029] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 In some embodiments, the magnetic base 12 includes a base body 121 and a connecting frame 122. The base body 121 has a telescopic groove 1211. One end of the connecting frame 122 is rotatably connected to a support frame 13 so that the support frame 13 can rotate relative to the connecting frame 122 about a first direction. The other end of the connecting frame 122 is telescopically disposed in the telescopic groove 1211. Specifically, as shown... Figure 4 As shown, the base 121 may include a first housing 1212 and a second housing 1213 connected to the first housing 1212. The first housing 1212 has a limiting groove 12121 and together with the second housing 1213 forms a telescopic groove 1211. The first housing 1212 includes a protrusion 12122 protruding from the bottom of the limiting groove 12121. The connecting frame 122 has a connecting hole 1221 extending along the length of the connecting frame 122. When the connecting frame 122 is assembled to the base 121, the portion of the connecting frame 122 with the connecting hole 1221 can be accommodated within the telescopic groove 1211. The connecting hole 1221 is fitted onto the protrusion 12122 to limit the range of movement of the connecting frame 122 and prevent the connecting frame 122 from disengaging from the telescopic groove 1211. The magnetic fan 10 adjusts the position between the fan assembly 11 and the magnetic base 12 by the telescopic movement of the connecting bracket 122 relative to the base 121. Figure 8 When the magnetic base 12 is attached to the back of the mobile phone 20, the fan assembly 11 can protrude from the top of the mobile phone 20 by the telescopic movement of the connecting frame 122 relative to the base 121 and the rotation of the support frame 13 relative to the connecting frame 122. Combined with the rotation of the housing 111 relative to the support frame 13, the orientation of the air outlet 111b can be adjusted, for example, so that the air outlet 111b faces the user for cooling.

[0030] refer to Figure 9 and Figure 10When the connecting bracket 122 does not need to extend or retract relative to the base 121, the magnetic fan 10 can be stably placed on a support such as a desktop by rotating the support frame 13 relative to the connecting bracket 122. The orientation of the air outlet 111b can be adjusted by rotating the housing 111 relative to the support frame 13 to dissipate heat for the user or electronic equipment. Furthermore, in Figure 9 In the embodiment shown, electronic devices such as mobile phones 20 can be magnetically attached to the magnetic base 12, and the magnetic fan 10 can be used as a stand for mobile phones 20 or electronic devices, improving the convenience of use and expanding the application scenarios of the magnetic fan 10.

[0031] Of course, for reference Figure 11 When the connecting bracket 122 does not need to extend or retract relative to the base 121, the fan assembly 11 can be stacked on the magnetic base 12 by rotating the support bracket 13 relative to the connecting bracket 122. The airflow from the fan assembly 11 to the back of the phone 20 increases air convection, cools the user's hand, and provides some cooling for the phone 20.

[0032] Furthermore, one of the base 121 and the connecting frame 122 is provided with a locking block 12c, and the other is provided with a plurality of first locking slots 12d distributed along the telescopic direction, so that during the telescopic extension and retraction of the connecting frame 122 relative to the base 121, the locking block 12c moves from one first locking slot 12d to another. For example, as shown... Figure 4 As shown, the base 121 may be provided with a locking block 12c, and the connecting frame 122 may have a first locking groove 12d. During the extension and retraction of the connecting frame 122 relative to the base 121, the locking block 12c of the base 121 moves from one first locking groove 12d to another first locking groove 12d to achieve locking of the base 121 and the connecting frame 122, maintaining the relative position of the fan assembly 11 and the magnetic base 12. When the user needs to drive the connecting frame 122 to extend and retract relative to the base 121 again, it is only necessary to overcome the resistance of the locking block 12c relative to the groove wall of the first locking groove 12d, thereby conveniently controlling the extension and retraction length of the connecting frame 122 relative to the base 121.

[0033] Specifically, the locking block 12c can be cylindrical. The protrusion 12122 of the first housing 1212 has a locking block groove 12124 for accommodating and limiting the locking block 12c, and a locking block opening 12125 communicating with the telescopic groove 1211. After the locking block 12c is disposed in the locking block groove 12124, part of the structure of the locking block 12c protrudes from the protrusion 12122 through the locking block opening 12125 for engaging with the first locking groove 12d of the connecting frame 122.

[0034] refer to Figure 2 , Figure 3 and Figure 4In some embodiments, the magnetic holder 12 includes a first surface 12a and a second surface 12b disposed opposite to each other. The first surface 12a is used to attach to an external device, and the magnetic holder 12 includes a hanging member 123 disposed on the side where the second surface 12b is located. The hanging member 123 is used to hang the magnetic fan 10 on an external support. Specifically, the first housing 1212 has a first surface 12a, which is located on the side of the first housing 1212 opposite to the second housing 1213. The second housing 1213 has a second surface 12b, which is located on the side of the second housing 1213 opposite to the first housing 1212. The magnetic holder 12 includes a magnetic cover 124 and a magnet 125 disposed on a first housing 1212. The magnetic cover 124 and the magnet 125 may be annular. The first housing 1212 may have an annular groove 12123. The magnet 125 is accommodated in the groove 12123. The magnetic cover 124 covers the groove 12123 and is connected to the first housing 1212. The connection method may be adhesive bonding or snap-fit, so as to fix the magnetic cover 124 to the first housing 1212 and prevent the magnet 125 from detaching from the groove 12123. The magnet 125 can be used for magnetic attraction with external devices to attract the magnetic fan 10 to the external device.

[0035] In some embodiments, the magnetic fan 10 may include accessories such as a magnetic sheet. For a mobile phone 20 equipped with a magnetic ring inside, the magnetic base 12 is directly attracted to the mobile phone 20 through the magnet 125. For a mobile phone 20 without a magnetic ring inside, the magnetic sheet can be pasted on the back of the mobile phone 20, and then the magnetic base 12 can be attracted to the magnetic sheet to attract the magnetic fan 10 to the mobile phone 20.

[0036] Continue to refer to Figure 2 , Figure 3 and Figure 4 In some embodiments, the hanging member 123 may include an integrally formed first end 1231 and second end 1232, with the first end 1231 of the hanging member 123 fixedly connected to the second housing 1213. During use, the user can squeeze a collar or backpack strap, etc., between the second end 1232 of the hanging member 123 and the seat 121, thereby increasing the gap between the second end 1232 of the hanging member 123 and the seat 121, thus opening the hanging member 123 relative to the seat 121. The deformation of the bent portion of the hanging member 123 can accumulate elastic potential energy. In other words, when a support with thickness enters the space between the hanging member 123 and the base 121, it can cause the bent part of the hanging member 123 to undergo elastic deformation. The restoring force of the elastic deformation causes the second end 1232 of the hanging member 123 to tend to converge towards the base 121, thereby reliably clamping the support such as the collar or backpack strap between the hanging member 123 and the base 121, preventing the magnetic fan 10 from easily falling off the external support.

[0037] Continue to refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the housing 111 includes a first mounting base 1111 and a second mounting base 1112 connected to the first mounting base 1111. The first mounting base 1111 has a first air inlet 111a and an air outlet 111b, with the air outlet 111b located on the side of the first mounting base 1111. A fan assembly 112 is disposed within the first mounting base 1111, and a power module 113 is disposed within the second mounting base 1112 and used to supply power to the fan assembly 112. The magnetic base 12 can be stacked on the side of the second mounting base 1112 opposite to the first mounting base 1111 via a support frame 13 to reduce the size of the magnetic fan 10 and facilitate storage.

[0038] refer to Figure 3 and Figure 5 In some embodiments, the power module 113 may include a battery 1131 and a circuit board 1132. The circuit board 1132 is electrically connected to the battery 1131, and the fan assembly 112 is electrically connected to the circuit board 1132. The battery 1131 may be a lithium battery capable of repeated charging and discharging, sufficient to provide power to the fan assembly 112. The control circuit of the fan assembly 112 may be integrated on the circuit board 1132 to realize functions such as turning on and off the magnetic fan 10.

[0039] refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, an air intake channel 1113 extending circumferentially around the fan assembly 11 is formed between the first mounting base 1111 and the second mounting base 1112, and the air intake channel 1113 communicates with the first air inlet 111a. The air intake channel 1113 may surround the entire fan assembly 11. One end of the support frame 13 extends into the air intake channel 1113 and is rotatably connected to at least one of the first mounting base 1111 and the second mounting base 1112. Alternatively, one end of the support frame 13 extends between the first mounting base 1111 and the second mounting base 1112. In other embodiments, the air intake channel 1113 does not necessarily surround the entire fan assembly 11; for example, the central angle of the air intake channel 1113 is 270 degrees to 300 degrees. In some embodiments, the first mounting base 1111 and the second mounting base 1112 may be cylindrical and have substantially the same diameter, so that the fan assembly 11 is cylindrical in shape. The first mounting base 1111 and the second mounting base 1112 are fixedly connected and have an axial gap between them to form an air intake channel 1113. The width of the air intake channel 1113 in the axial direction of the fan assembly 11 is not less than the thickness of the support frame 13, so that one end of the support frame 13 can rotate relative to the first mounting base 1111 in the air intake channel 1113.

[0040] refer to Figure 2 , Figure 3, Figure 5 and Figure 7 In some embodiments, the second mounting base 1112 forms a protruding mounting portion 1112a on the side facing the first mounting base 1111. The mounting portion 1112a is detachably connected to the first mounting base 1111, and one end of the support frame 13 extends into the air intake channel 1113 and is rotatably connected to the mounting portion 1112a. Specifically, the mounting portion 1112a can be ring-shaped, and the first mounting base 1111 is provided with a connecting platform 1111a that matches the mounting portion 1112a. The mounting portion 1112a and the connecting platform 1111a each have a cable routing hole 111c. The cable routing hole 111c is used to pass cables through to realize the electrical connection between the power module 113 and the fan assembly 11, preventing the cables from getting tangled or damaged when the fan assembly 11 rotates relative to the support frame 13. Multiple first air inlets 111a can be provided and extend circumferentially along the connecting platform 1111a and are spaced apart around the connecting platform 1111a. The mounting part 1112a is detachably connected to the connecting platform 1111a, for example, by means of screws.

[0041] Furthermore, the fan assembly 11 includes a resilient locking member 114 disposed on the mounting portion 1112a, and the support frame 13 has a limiting hole 131, which is fitted onto the mounting portion 1112a, and the inner wall of the limiting hole 131 has a plurality of second slots 131a. During the rotation of the support frame 13 relative to the mounting base, the resilient locking member 114 can extend and retract relative to the mounting portion 1112a to engage with the second slots 131a. Specifically, as... Figure 5As shown, the elastic clip 114 can be approximately V-shaped. The second mounting base 1112 may have a clip groove 1112b for accommodating the elastic clip 114 within the mounting portion 1112a, and a clip opening 1112c provided on one side wall of the clip groove 1112b. The elastic clip 114 is accommodated and confined within the clip groove 1112b, and the protruding portion of the elastic clip 114 protrudes from the mounting portion 1112a through the clip opening 1112c for engaging with the second clip groove 131a of the support frame 13. The inner wall of the limiting hole 131 of the support frame 13 may have multiple teeth 132, and the second clip groove 131a is formed between adjacent teeth 132. During the rotation of the support frame 13 relative to the fan assembly 11, the support frame 13 rotates relative to the mounting portion 1112a. The elastic locking member 114, due to its elastic deformation, is pressed against the locking teeth 132, causing it to extend and retract relative to the mounting portion 1112a, sliding from one second locking slot 131a into another adjacent second locking slot 131a. This locks the support frame 13 and the mounting portion 1112a, preventing the fan assembly 11 from easily rotating relative to the support frame 13 and maintaining the relative position of the air outlet 111b. When the user needs to drive the support frame 13 to rotate relative to the fan assembly 11 again, it only needs to overcome the resistance of the locking teeth 132 on the elastic locking member 114. During this process, the elastic locking member 114 and the locking teeth 132 continuously and alternately engage, providing a tactile feedback and ensuring reliable positioning of the fan assembly 11 on the support frame 13 to maintain the orientation of the air outlet 111b. In some embodiments, the elastic clip 114 can be formed by processing a sheet-like substrate with elasticity, such as a stainless steel spring. The specific processing techniques are disclosed in the prior art and will not be described in detail here.

[0042] In some embodiments, the connection frame 122 and the locking block 12c can also be coupled by the elastic locking element 114 and the mounting part 1112a, so that the locking block 12c makes elastic contact with the groove wall of the first locking groove 12d to obtain a better locking feel.

[0043] refer to Figure 2 , Figure 3 and Figure 5In some embodiments, the second mounting base 1112 may include a protective shell 11121 and a cover 11122. The cover 11122 has a mounting portion 1112a on the side facing the first mounting base 1111. The protective shell 11121 has a mounting cavity 1112d for mounting the power module 113. The cover 11122 has a mounting portion 1112a on the side facing away from the mounting cavity 1112d. The cover 11122 covers the mounting cavity 1112d and is connected to the protective shell 11121 to protect the power module 113 disposed in the mounting cavity. The wiring hole 111c communicates with the mounting cavity 1112d. In some embodiments, the cover 11122 has a locking groove 1112e, and the protective shell 11121 has a locking protrusion 1112f that matches the locking groove 1112e of the cover 11122. The protective shell 11121 matches the locking groove 1112e of the cover 11122 through the locking protrusion 1112f, so as to realize the assembly of the protective shell 11121 and the cover 11122.

[0044] refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 In some embodiments, the first mounting base 1111 has a second air inlet 1111b on the side opposite to the second mounting base 1112. Specifically, the first mounting base 1111 includes a protective cover 11111, a mounting plate 11112 connected to one side of the protective cover 11111, a light-transmitting element 11113 connected to the other side of the protective cover 11111, and a decorative cover 11114 connected to the light-transmitting element 11113. The protective cover 11111 and the light-transmitting element 11113 enclose a receiving cavity 11115. The fan assembly 112 is connected to the mounting plate 11112 and housed within the receiving cavity 11115. The protective cover 11111 has an air outlet 111b, and the mounting plate 11112 is connected to the second mounting base 1112 and has a first air inlet 111a. Along the axial direction of the fan assembly 112, the decorative cover 11114 is located on the side of the light-transmitting element 11113 away from the second mounting base 1112. The decorative cover 11114 and the light-transmitting element 11113 form a second air inlet 1111b. The first air inlet 111a and the second air inlet 1111b are distributed on opposite sides of the axial direction of the fan assembly 112. Since the first air inlet 111a and the second air inlet 1111b are provided on opposite sides of the axial direction of the fan assembly 112, the fan assembly 11 can have a larger air intake volume than a single air inlet during operation, so as to form a better positive pressure effect in the receiving cavity 11115, increase the air flow rate of the air outlet 111b, and enhance the heat dissipation effect.

[0045] Specifically, such as Figure 6As shown, the mounting plate 11112 has a first mounting groove 1111c, and the protective cover 11111 is provided with a first mounting protrusion 1111d that matches the first mounting groove 1111c. The protective cover 11111 matches the first mounting groove 1111c of the mounting plate 11112 via the first mounting protrusion 1111d to connect and confine the protective cover 11111 to the mounting plate 11112, preventing the protective cover 11111 from rotating relative to the mounting plate 11112. In some embodiments, the light-transmitting element 11113 has a second mounting groove 1111e, and the mounting base is provided with a second mounting protrusion 1111f that matches the second mounting groove 1111e. The light-transmitting element 11113 matches the second mounting protrusion 1111f of the mounting plate 11112 via the second mounting groove 1111e to assemble the light-transmitting element 11113 onto the mounting plate 11112.

[0046] Continue to refer to Figure 2 , Figure 3 , Figure 6 and Figure 7 In some embodiments, the fan assembly 11 includes a circuit board 115, a light-emitting module 116, a display module 117, and a fixing member 118. The circuit board 115 is connected to a light-transmitting element 11113. The light-emitting module 116 and the display module 117 are electrically connected to the circuit board 115 and disposed on the side of the circuit board 115 opposite to the second mounting base 1112. The light-transmitting element 11113 covers the light-emitting module 116, and the decorative cover 11114 covers the display module 117. The mounting plate 11112 may have a wiring channel 1111g, through which the circuit board 115 can be electrically connected to the power module 113 to supply power to the light-emitting module 116 and the display module 117. The second air inlet 1111b extends from the side of the light-transmitting element 11113 opposite to the second mounting base 1112, through the circuit board 115, and into the receiving cavity 11115. Specifically, the light-transmitting element 11113 has a receiving groove 1111h and a first through hole 1111i on the side facing the mounting base. The fixing element 118 has a second through hole 1181. The circuit board 115 and the light-emitting module 116 are received and confined within the receiving groove 1111h. The display module 117 passes through the first through hole 1111i and the second through hole 1181 and is covered by a decorative cover 11114. In some embodiments, the light-transmitting element 11113 may have a frosted surface and cover the light-emitting module 116, which has a certain degree of light transmittance, for example, a light transmittance of 50%-60%. The light-emitting module 116 may be an LED lamp, thereby providing supplemental lighting for the user when powered on.

[0047] like Figure 12When the magnetic base 12 is attached to the back of the phone 20, the telescopic movement of the connecting bracket 122 relative to the base 121, combined with the rotation of the support bracket 13 relative to the connecting bracket 122, allows the fan assembly 11 to protrude from the top of the phone 20. Furthermore, the rotation of the housing 111 relative to the support bracket 13 ensures that the light-emitting side of the light-emitting module 116 faces the face, thus providing supplementary lighting for the user's photography. Figure 11 In the illustrated embodiment, when the magnetic fan 10 is stacked on the back of the mobile phone 20, the light-emitting module 116 can also emit light to provide backlighting for the user in dim environments, improving eye comfort. Figure 9 In the illustrated embodiment, when the magnetic fan 10 is used as a phone holder 20, the light-emitting module 116 can also emit light to provide backlighting for the user in dim environments, improving eye comfort. Of course, in Figure 10 In the illustrated embodiment, the magnetic fan 10 is supported on a table or other support via the magnetic base 12. The light-emitting module 116 can also emit light, serving as background lighting, or combining the functions of air blowing, heat dissipation, and supplementary lighting. That is, the operation of the light-emitting module 116 and the operation of the fan assembly 112 can be independent of each other.

[0048] The decorative cover 11114 covers the display module 117 and has a certain degree of light transmittance, for example, a light transmittance of 50%-60%. The display module 117 can be a digital tube for displaying the power information of the battery 1131. In some embodiments, the light-transmitting element 11113 has a through hole 1111j, and the fixing member 118 and the light-transmitting element 11113 are axially spaced apart in the fan assembly 11. The through hole 1111j is configured as part or all of the second air inlet 1111b.

[0049] refer to Figure 3 , Figure 6 , Figure 7 and 13In some embodiments, the fan assembly 112 may include a drive element 1121 and a fan blade 1122 linked to the drive element 1121. The fan assembly 112, driven by the drive element 1121, rotates the fan blade 1122 around the axial direction of the drive element 1121 to draw in gas from the first air inlet 111a and blow it out from the air outlet 111b. The drive element 1121 may be a combination of a rotor and a stator to reduce the size of the magnetic fan 10. The fan blade 1122 includes an integrally formed blade 11221, a support 11222, and a retaining ring 11223. The support 11222 has a groove 1122a for accommodating the drive element 1121. One end of the blade 11221 is connected to the support 11222, and the other end is connected to the retaining ring 11223, fixing both ends of the blade 11221 to prevent the blade 11221 from shaking during high-speed rotation, thereby enhancing the stability of the fan blade 1122. In the axial direction of the fan blade 1122, a retaining ring 11223 is located at the end of the blade 11221 opposite to the second mounting base 112 and surrounds the support 11222, and is radially spaced from the support 11222. The spaced arrangement of the retaining ring 11223 and the support 11222 ensures that there is no obstruction between the second air inlet 1111b and the blade 11221, allowing the blade 11221 to directly engage with the second air inlet 1111b to improve air intake efficiency. In the radial direction of the fan blade 1122, one side of the blade 11221 is concave, and the opposite side is convex, forming an arc-shaped surface. When rotating, the arc-shaped surface can exert a force on the surrounding gas, causing the airflow to form a directional flow, thereby achieving the effect of driving the airflow. In some embodiments, the drive component 1132 can be a combination of a rotor and a stator to reduce the size of the magnetic fan 10.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
