Therefore, they should not be construed as limitations on this application.

[0031] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] This utility model provides a magnetic coupling component that can be used in high-voltage DC fans or other transmission components. This embodiment is described using a high-voltage DC fan as an example. The high-voltage DC fan mainly includes a motor assembly and a pump head assembly connected by a transmission connection. No special limitations are placed on the motor assembly and the pump head assembly.

[0034] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the magnetic coupling assembly includes a driving magnetic structure and a driven magnetic structure respectively mounted on the driving shaft and the driven shaft; the driving magnetic structure includes a driving seat 100 and a plurality of first magnets 200, the inner side of the driving seat 100 is provided with a first mounting groove 110 for mounting the first magnets 200, and the side of the first magnets 200 near the driven magnetic structure is provided with a potting layer 300, and the driving seat 100 is engaged with the potting layer 300; the driven magnetic structure includes a driven seat 400 and a plurality of second magnets, the inner side of the driven seat 400 is provided with a plurality of second mounting grooves for mounting the second magnets.

[0035] Understandably, this invention provides a first mounting groove 110 and a second mounting groove on the drive seat 100 and the driven seat 400, respectively, to limit and fix the first magnet 200 and the second magnet. Furthermore, the drive seat 100 engages with the potting layer 300, further securing the position of the first magnet 200. The connection method is simple and easy to disassemble. This invention avoids the traditional method of fixing magnets using bolts, screws, or specialized fixing devices. The magnet is fixed simply by providing mounting grooves and an engaging connection, making the fixing method simple and disassembly convenient.

[0036] In some embodiments of this utility model, such as Figure 4 As shown, the potting layer 300 includes a mounting plate 310 and a partition plate 320. The mounting plate 310 has a through hole 311 in the middle. There are multiple partition plates 320, which are axially and evenly arranged on the side of the mounting plate 310 near the first magnet 200. Adjacent partition plates 320 form a second mounting groove corresponding to the first mounting groove 110. The first mounting groove 110 and the second mounting groove cooperate with each other to limit and fix the first magnet 200.

[0037] Optionally, one end of the partition plate 320 extends along a first direction and protrudes beyond the outer edge of the mounting plate 310 to form a first extension 321, and the other end of the partition plate 320 extends along a second direction and protrudes beyond the inner edge of the mounting plate 310 to form a second extension 322. The first direction is the direction from the through hole 311 to the outer edge of the mounting plate 310, and the second direction is opposite to the first direction. The drive seat 100 is engaged with the potting layer 300 through the first extension 321 and the second extension 322. Since the partition plate 320 can be engaged with the drive seat 100, the installation and disassembly process does not require any auxiliary tools, making the replacement process more convenient.

[0038] In some embodiments of this utility model, such as Figure 1 and Figure 5 As shown, the drive seat 100 includes an end cap 120, a first annular plate 130, and a second annular plate 140. The first annular plate 130 extends from the outer edge of the end cap 120 toward the potting layer 300, and the inner side of the first annular plate 130 is provided with a first engaging portion that matches the first extension 321. The second annular plate 140 extends from the middle of the end cap 120 toward the potting layer 300, and the outer side of the second annular plate 140 is provided with a second engaging portion that matches the second extension 322. In addition, a bearing mounting portion 150 is provided at the middle of the outer side of the drive seat 100 for mounting the drive shaft. The structure of the driven seat 400 is preferably the same as that of the drive seat 100.

[0039] Understandably, the first engaging portion can be a protruding structure extending from the inner side of the first annular plate 130 toward the center of the drive seat 100, and the second engaging portion can be a protruding structure extending from the outer side of the second annular plate 140 toward the outer edge of the drive seat 100. In use, the first extension 321 and the first engaging portion can be matched by pressing and rotating to achieve the engaging connection between the drive seat 100 and the potting layer 300.

[0040] In some embodiments of this utility model, such as Figure 2 As shown, a wind-blocking baffle 500 is provided between the driving magnetic structure and the driven magnetic structure.

[0041] Understandably, the wind baffle 500 can separate the drive seat 100 and the driven seat 400, effectively preventing gas from entering the motor through the axial clearance, reducing axial clearance leakage, ensuring wind resistance, and improving the volumetric efficiency and working performance of the high-pressure air pump.

[0042] Optionally, the areas of both the drive seat 100 and the driven seat 400 are smaller than the area of ​​the baffle 500, resulting in better wind resistance. Furthermore, an annular wind-resistant partition can be provided on the outer side of the baffle 500, located outside the drive seat, to further enhance the wind resistance. Additionally, the baffle 500 has multiple mounting holes 510 circumferentially, through which the baffle 500 is connected to the pump head assembly.

[0043] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
