[0037] In one embodiment of the magnetic POGO PIN quick-release fan of this utility model, please refer to... Figures 1 to 5A magnetic POGO PIN quick-release fan includes an outer frame 100, an adapter plate 200, and a detachable fan module 300. The outer frame 100 has an inner cavity 110 with a top opening. The bottom of the inner cavity 110 is integrally formed with a mounting groove 120. The mounting groove 120 includes a positioning post 130 extending vertically upward from its center. A first magnetic ring 140 is coaxially embedded on the outer periphery of the positioning post 130. The top end of the positioning post 130 extends beyond the upper surface of the first magnetic ring 140. One end of the side wall of the mounting groove 120 is recessed downward to form a stepped mounting position 150. The mounting position 150 has an upwardly extending fixing post 151. The adapter plate 200 includes a POGO PIN male connector 210, a fixing hole 230, and a first PCB board 220. The POGO PIN male connector 210 and the fixing hole 230 are located on the first PCB board 220. The fixing hole 230 engages with the fixing post 151 to axially fix the adapter plate 200 at the bottom of the inner cavity 110. The detachable fan module 300 includes a motor assembly 310, a second PCB board 320, and a fan body 330. The fan body 330 has multiple fan blades 331 on its outer periphery. The second PCB board 320 is located at the bottom of the motor assembly 310. The motor assembly 310 has a positioning tube 311 extending vertically downwards from the bottom surface of the second PCB board 320. The fan body 330 is rotatably connected to the positioning tube 311 via a rotating shaft 331 and is located above the motor assembly 310. The bottom end of the positioning tube 311 has a stepped hole 312. A second magnetic ring 340, which magnetically engages with the first magnetic ring 140, is coaxially embedded in the stepped hole 312. The positioning tube 311 is axially magnetically positioned by adapting to the positioning post 130 through the stepped hole 312. The bottom surface of the second PCB board 320 has an annular female connector 321 electrically connected to the POGO PIN male connector 210.

[0038] Specifically, the outer frame 100 has a stepped mounting position 130, and the mounting position 130 extends upward to a fixing post 151. The first PCB board 220 of the adapter board has a fixing hole 230. The adapter board 200 is fixed to the bottom of the inner cavity 110 of the outer frame by snapping into the fixing post 151 through the fixing hole 230. The fixing hole 230 and the fixing post 151 are engaged and axially limited to ensure that the adapter board 200 is stable and does not fall off. Moreover, the disassembly and assembly method is simple and can be disassembled and separated without professional tools, which is convenient for cleaning the outer frame 100. Since the mounting groove 120 of the outer frame is provided with a coaxial positioning post 130 and a first magnetic ring 140 at its center, and the positioning tube 311 at the bottom of the detachable fan module 300 is provided with a stepped hole 312, and a coaxial second magnetic ring 340 is embedded in the stepped hole 312, the stepped hole 312 of the detachable fan module is aligned with the positioning post 130 for positioning, and at the same time the first magnetic ring 140 and the second magnetic ring 340 are automatically guided and attracted, magnetically fixing the detachable fan module 300 to the inner cavity 110 of the outer frame; the coaxial design ensures vertical and precise alignment, prevents deviation during assembly, and avoids poor contact caused by misalignment of the POGO PIN male connector 210 and female connector 321. Additionally, the adapter board 200 features a POGO PIN male connector 210, and the second PCB board 320 at the bottom of the detachable fan module features a ring-shaped female connector 321. The ring-shaped design of the female connector 321 ensures that the detachable fan module 300, after being rotated into the inner cavity 110, makes contact with the POGO PIN male connector 210, enabling the fan to function normally. No professional tools or personnel are required; individuals can quickly install the fan. When it is necessary to separate the detachable fan module 300 from the outer frame 100, simply lift the fan blades 332. When the pulling force exceeds the attraction between the magnetic rings, the fan breaks free from the magnetic rings, completing the disassembly of the detachable fan module 300. The fan can be quickly removed by hand for easy cleaning. If the fan malfunctions, only the detachable fan module 300 needs to be removed for replacement or repair; other components remain unchanged. This type of quick-release structure with magnetic POGO PIN connection reduces the disassembly and assembly process, allowing for quick and efficient disassembly and assembly by hand.

[0039] Preferably, the outer frame 100 is also provided with assembly stations 180 at its four corners. Specifically, the fan can be stably assembled onto the terminal through the assembly stations 180 on the outer frame without affecting the individual quick-release and quick-installation of the detachable fan module 300.

[0040] Furthermore, the annular female connector 321 includes at least two concentrically arranged conductive rings 322, and the POGO PIN male connector 210 is provided with multiple spring pins 211. The multiple conductive rings 322 and the multiple spring pins 211 form an elastic compression connection; the conductive rings 322 are coaxially arranged with the positioning tube 311. Specifically, the spring pins 211 are elastic. When the annular female connector 321 of the second PCB board is pressed against the POGO PIN male connector 210, the spring pins 211 on the POGO PIN male connector 210 will retract downwards to relieve the downward pressure of the motor assembly 310 and the second PCB board 320, reduce the gravitational contact friction between the female connector 321 and the POGO PIN male connector 210, thereby preventing the oxidation and peeling of the surface plating of the conductive rings 322 and the spring pins 211, which would cause poor contact.

[0041] Furthermore, the surface of the conductive ring 322 is gold-plated. Specifically, the gold plating layer has strong conductivity and corrosion resistance, improving the durability of the female connector 321.

[0042] Furthermore, multiple conductive rings 322 are arranged radially from the outside to the inside on the bottom surface of the second PCB board 320, with the innermost conductive ring 322 having a gap from the outer wall of the positioning tube 311. Specifically, the gap ensures that when the stepped hole 312 of the positioning tube is fitted with the positioning post 130, it does not easily rub against the conductive ring 322.

[0043] Furthermore, the height of the fixing post 151 is lower than the top of the side wall of the mounting groove 120. The fixing post 151 is also provided with a connecting hole 152. A locking member passes through the fixing hole 230 and the connecting hole 152 to lock the adapter plate 200. Specifically, the height of the fixing post 151 being lower than the top of the side wall of the mounting groove 120 facilitates optimized spatial layout and saves longitudinal space. The locking member enhances the axial limiting effect, further locking and fixing the adapter plate 200 within the outer frame 100. Preferably, there are two fixing posts 151, respectively located on both sides of the POGOPIN male connector 210. Specifically, they limit the two sides of the adapter plate 200, ensuring the assembly stability of the adapter plate 200 within the outer frame 100.

[0044] Furthermore, one end of the mounting position 150 extends to the side wall of the outer frame 100, and the adapter plate 200 is connected to a wire 240. The end of the wire 240 is provided with an electrical connector 250. The wire 240 and the electrical connector 250 extend along the mounting position 150 to the outside of the outer frame 100. Specifically, the stepped mounting position 150 facilitates the storage of the wire 240 to prevent the wire 240 from being exposed and pulled, and the electrical connector 250 is located on the outside for easy plugging and unplugging.

[0045] Furthermore, the top of the positioning post 130 is provided with a clearance hole 131 to prevent the rotating shaft 331 from being exposed to air. Specifically, since the rotating shaft 331 is rotatably connected to the positioning tube 311 of the motor assembly, and the end of the positioning tube 311 is provided with a stepped hole 312, the positioning tube 311 is fully connected, and the positioning post 130 fits into the stepped hole 312 to enter the positioning tube 311. The clearance hole 131 prevents the end of the rotating shaft 311 from being exposed to air, making the detachable fan module 300 compact and space-saving.

[0046] Furthermore, the mounting groove 120 is also provided with a limiting sleeve 160, the inner wall of which is in clearance fit with the outer diameter of the first magnetic ring 140. The outer wall of the limiting sleeve 160 is provided with circumferentially distributed protrusions 161. Specifically, the protrusions 161 are used to limit the outer side of the end of the positioning sleeve 160, thereby enhancing the stability of the connection between the detachable fan module 300 and the outer frame 100.

[0047] Furthermore, at least three radially extending limiting bosses 170 are provided on the inner sidewall of the mounting groove 120 for radially limiting the second PCB board 320. Specifically, the limiting bosses 170 engage with the edge of the second PCB board 320 to stabilize the crimping between the female connector 321 and the POGO PIN male connector 210, thereby reducing the vibration impact of the fan blade 332 during operation.

[0048] Furthermore, the first magnetic ring 140 and the second magnetic ring 340 are made of neodymium iron boron. Specifically, neodymium iron boron has the strongest magnetic force in the same volume and is highly machinable, making it suitable for designs of different sizes and shapes.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
