Furthermore, the connection through the connecting through hole 1141 ensures a highly reliable connection, meeting the applicability requirements for outdoor scenarios.

[0038] refer to Figure 2 In some embodiments, the magnetic support structure 1 includes an annular platform 11 disposed on the outside of the housing 110 of the portable fan 100 and arranged coaxially with the fan shaft, and a magnetic part 12 disposed on the surface of the annular platform 11 facing away from the housing 110 of the fan.

[0039] The angle adjustment structure 2 is provided with a magnet (not shown in the figure) corresponding to the position of the magnetic attraction part 12. The angle adjustment structure 2 and the magnetic support structure 1 are detachably connected by the magnetic attraction part 12 and the magnet.

[0046] In some embodiments, the connector 114 is columnar and has a connecting through hole 114 along its axial direction.

[0047] In other embodiments, the intermediate cylinder 112 and the connector 114 are integrally formed. This integral structural design improves the reliability of the structure.

[0048] In some embodiments, the outer diameter of the cylindrical body 111 is smaller than the outer diameter of the intermediate cylindrical body 112, and the outer diameter of the intermediate cylindrical body 112 is smaller than the outer diameter of the annular disk 113.

[0055] In some embodiments, the ring 21 is designed directly using a magnetic material to form the magnetic part described above.

[0056] In another embodiment, the ring 21 is magnetized using a magnetization process to form the magnetic attraction part described above.

[0057] Specifically, addressing the drawback of a type of portable desktop fan that lacks angle adjustment, this application provides a solution that allows the fan to connect to a mobile phone holder with Magsafe magnetic attachment, eliminating the need to carry an additional holder and further enhancing its portability.

[0058] The overall effect is shown below. The image below only shows the desktop application of the small fan with the bracket of this application installed. At the same time, it can be used for wall mounting, clip-on, vehicle mounting and other application scenarios through various standard interfaces, which greatly expands the application range of the small fan.

[0059] Main functions:

[0060] The bracket in this application can achieve the following functions to enable all-weather operation.

[0061] 1) The small fan and the magnetic bracket can be quickly attached and detached using magnetic attraction, allowing for fan angle control (more suitable for indoor scenarios).

[0062] 2) The small fan and the universal photography accessory (including the universal photography accessory in the external multi-degree-of-freedom device 200) are installed more securely and reliably to achieve fan angle control (more suitable for outdoor scenes).

[0063] Main design:

[0064] The bracket of this application includes a magnetic support structure 1 and an angle adjustment structure 2. The bottom of the magnetic support structure 1 is designed with an iron ring or a Magsafe receiving magnet, which is connected to the angle adjustment structure 2.

[0065] The cylinder 111 and the ring disc 113 are made of nylon plastic, while the intermediate cylinder 112 and the connecting body 114 are made of aluminum alloy. The surface of the ring disc 113 facing away from the intermediate cylinder 112 has an iron ring or magnet. Specifically, the intermediate cylinder 112 and the connecting body 114 are integrally formed.

[0066] refer to Figure 3 The dimensions are as follows:

[0067] D1 is taken as the standard outer diameter of the magnetic suction part 12, i.e., 54-60mm.

[0068] D2 is the outer diameter of the intermediate cylinder 112, which is consistent with the size of the central disc on the back of the fan to avoid affecting the air intake at the back of the fan. This size is 35-40mm.

[0069] D3 is the outer diameter of the cylinder 111, which is set between 32-42mm. The cylinder 111 is used to connect to the back cover 110 of the fan to ensure a certain contact area and to ensure the strength of the magnetic support structure 1.

[0070] The D4 connection has a through-hole diameter with a 3 / 8” interface (approximately 9mm).

[0071] In this application, considering that the hole reserved for the bearing of a 4-inch small fan motor is usually 8mm, which is between the 3 / 8” or 1 / 4” interface size, a 3 / 8” interface is reserved. This setting does not affect the maintenance of the fan later (the 1 / 4” interface is more universal on small photography equipment).

[0072] Further, refer to Figure 5 and Figure 6 To ensure that the magnetic support structure 1 does not obstruct the fan's air intake, with D1 = 55mm, the distance H between the lower end face of the ring plate 113 and the lower end face of the ring platform 111 must be at least 8-15mm. Testing has shown that this does not affect the normal operation of the fan. Simultaneously, this distance avoids interference from the bracket of this application to the magnetic field of the internal motor of the fan. It is understood that the lower end face of the ring platform 111 is the end face that fits against the fan housing, while the lower end face of the ring plate 113 is the end face facing the fan housing.

[0073] Extended applications:

[0074] refer to Figure 7 In some scenarios (such as outdoor environments), magnetic connection is not a stable connection method. In this case, the connection through hole 1141 of the standard 3 / 8” interface (or 1 / 4” in the center part of the magnetic support structure 1) can be used for expansion connection.

[0075] A second aspect of the embodiments of this disclosure provides a portable fan 100, the portable fan 100 including the bracket described above.

[0076] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
