[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0022] Please see Figure 1-5This utility model provides a technical solution: a high-efficiency silent fan for oxygen concentrators, including a silent fan body 1, a drive device 2, a connection port 3, a slot 4, a transmission head 5, an insertion rod 6, a magnetic 7, and an iron block 8. The drive device 2 is fixedly installed on one side of the silent fan body 1. The connection port 3 is opened on one side of the drive device 2. Slots 4 are symmetrically opened on both sides of the connection port 3 on one side of the drive device 2. The transmission head 5 is movably connected inside the connection port 3. An insertion rod 6 is symmetrically fixedly installed on one side of the transmission head 5. An insertion rod 6 is symmetrically fixedly installed on one side of the insertion rod 6. Magnetic 7 is fixedly installed on one side of each insertion rod 6, and an iron block 8 is movably contacted on one side of each magnetic 7. The magnetic poles of the magnetic 7 and the iron block 8 are opposite and have mutual attraction. The iron block 8 is located inside the slot 4. A dustproof net 9 is movably connected to the other side of the silent fan body 1. Multiple disassembly components 10 are provided at the outer end of the dustproof net 9. A maintenance component 11 is provided on the top of the drive device 2.

[0023] The staff inserts the insertion rod 6 on one side of the dustproof net 9 into the slot 4, and at the same time inserts the transmission head 5 into the connection port 3. The insertion rod 6 is fixed by the attraction between the magnetic part 7 and the iron block 8, making the transmission head 5 more secure. Example 2

[0024] The disassembly assembly 10 includes a fixing slot 101, each fixing slot 101 being opened on the other side of the silent fan body 1, and a fixing block 102 being movably connected inside each fixing slot 101. The fixing block 102 and the fixing slot 101 are size-matched. Each fixing block 102 has symmetrical storage slots 103 inside, and multiple springs 104 are fixedly installed inside each storage slot 103. Multiple support plates 105 are installed on one side of each spring 104. A connecting plate 106 is fixedly installed on one side of each fixing block 102. The connecting plate 106 is fixedly connected to the dustproof net 9.

[0025] Before insertion, the support plate 105 is stored inside the storage slot 103. The worker inserts the fixing block 102 on one side of the dustproof net 9 into the fixing slot 101. After insertion, the support plate 105 is adjusted by the elasticity of the spring 104. The two support plates 105 are used to fix the fixing block 102 inside the fixing slot 101, thus fixing the dustproof net 9 in place. Example 3

[0026] The maintenance component 11 includes a connecting groove 111, each connecting groove 111 being opened on the top of the drive device 2, and a thermal expansion and contraction ring 112 being fixedly installed inside each connecting groove 111.

A sealing groove 116 is opened at the outer end of each connecting rod 114.

[0027] Then, the connecting rod 114 below the heat dissipation frame 115 is inserted into the inside of the connecting groove 111 to cool the heat conduction cylinder 113. The heat conduction cylinder 113 cools the thermal expansion and contraction ring 112, causing the internal space of the thermal expansion and contraction ring 112 to shrink. The thermal expansion and contraction ring 112 shrinks into the inside of the sealing groove 116, and the heat dissipation frame 115 is fixedly installed.

[0028] In summary, the working principle of this technical solution is as follows: Before insertion, the support plate 105 is housed inside the storage slot 103. The operator inserts the fixing block 102 on one side of the dustproof net 9 into the fixing slot 101. After insertion, the support plate 105 is adjusted using the elasticity of the spring 104. The two support plates 105 are used to fix the fixing block 102 inside the fixing slot 101, thus fixing the dustproof net 9 in place. The operator then inserts the insertion rod 6 on one side of the dustproof net 9 into the slot 4, and simultaneously... The transmission head 5 is inserted into the connector 3. The insertion rod 6 is fixed by the attraction between the magnetic 7 and the iron block 8, making the transmission head 5 more secure. Then, the connecting rod 114 below the heat dissipation frame 115 is inserted into the connecting groove 111 to cool the heat conduction cylinder 113. The heat conduction cylinder 113 cools the thermal expansion and contraction ring 112, causing the internal space of the thermal expansion and contraction ring 112 to shrink. The thermal expansion and contraction ring 112 shrinks into the sealing groove 116, and the heat dissipation frame 115 is fixedly installed.
