[0023] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] A magnetic levitation centrifugal blower comprises a magnetic levitation blower 1, an air inlet pipe 2 is fixedly connected to one side of the magnetic levitation blower 1, an anti-blocking mechanism is arranged on the outer side of the air inlet pipe 2, the air inlet pipe 2 is connected to the air inlet position of the magnetic levitation blower 1, so that the magnetic levitation blower 1 can take in air through the air inlet pipe 2, and the anti-blocking mechanism can be installed on the outer side of the air inlet pipe 2.

[0026] The anti-clogging mechanism includes a filter plate 31 arranged inside the air inlet pipe 2, a first hollow block 32 is fixedly connected to the outside of the air inlet pipe 2, a rotating rod 33 is rotatably connected inside the first hollow block 32, a gear 34 is fixedly connected to one side of the rotating rod 33, a rack 35 is slidably connected to the outside of the air inlet pipe 2, and the rack 35 and the gear 34 are meshed with each other, a slide groove 36 is opened on one side of the air inlet pipe 2, and a slider 37 is slidably connected to the air inlet pipe 2 located inside the slide groove 36, and the slider 37 is fixedly connected to the filter plate 31.

[0027] The filter plate 31 is located inside the air inlet pipe 2, so that when the magnetic levitation blower 1 takes in air through the air inlet pipe 2, the filter plate 31 can filter and block large and small debris, thereby preventing the magnetic levitation blower 1 from being blocked or damaged.

[0028] When the filter plate 31 is blocked after long-term use and needs to be unblocked, the rotating rod 33 can be directly rotated to drive the gear 34 to rotate, and the gear 34 will drive the rack 35 to move. The slider 37 can connect the rack 35 and the filter plate 31, so that the rack 35 can drive the filter plate 31 to move inside the air inlet pipe 2 through the slider 37 until it is moved out of the air inlet pipe 2. At this time, the debris on the surface of the filter plate 31 can be cleaned and unblocked. After unblocking, the filter plate 31 can be moved back to its original position. The rack 35 is located on the upper side of the slide groove 36, which can realize the closure of the slide groove 36, so that the air inlet pipe 2 can smoothly take in air.

[0029] See also Figure 4 A second hollow block 41 is fixedly connected to the lower side of the rack 35, and a bolt 42 is threadedly connected to the interior of the second hollow block 41. A threaded groove 43 is provided on one side of the slider 37, and the bolt 42 is threadedly connected to the interior of the threaded groove 43. The bolt 42 can be connected to the interior of the second hollow block 41 and the threaded groove 43, thereby achieving the function of fixedly connecting the rack 35 and the slider 37, so that the rack 35 can smoothly drive the slider 37 to move when moving. At the same time, the bolt 42 can also be disengaged from the threaded groove 43 by rotation, thereby facilitating the disassembly of the filter plate 31, and achieving the effect of replacing and cleaning the filter plate 31.

[0030] See also Figure 3 A support block 5 is provided on one side of the filter plate 31, and the support block 5 is fixedly connected to the magnetic levitation blower 1. The support block 5 can limit the filter plate 31, so that the filter plate 31 is not easily deformed and damaged backward when air enters.

[0031] See also Figure 2 A third hollow block 61 is fixedly connected to the upper side of the first hollow block 32, and a threaded rod 62 is connected to the inner thread of the third hollow block 61, and the threaded rod 62 is located on the upper side of the rotating rod 33. The threaded rod 62 can rotate inside the third hollow block 61, thereby realizing the up and down movement, and squeezing the rotating rod 33 when moving, so that the rotating rod 33 and the gear 34 are not easy to rotate, and then the rack 35 and the filter plate 31 are not easy to move, and are more stable.

[0032] See also Figure 2 A first limiting ring 71 is provided on one side of the first hollow block 32, and a second limiting ring 72 is provided on the side of the first hollow block 32 away from the first limiting ring 71, and the first limiting ring 71 and the second limiting ring 72 are both fixedly connected to the rotating rod 33. The first limiting ring 71 and the second limiting ring 72 can limit the rotating rod 33, so that the rotating rod 33 is not easy to move, thereby making the gear 34 not easy to move, which can make the gear 34 not easy to disengage from the meshing with the rack 35.

[0033] See also Figure 1An n-shaped reinforcement block 8 is provided on the outer side of the rack 35, and the n-shaped reinforcement block 8 is fixedly connected to the air inlet pipe 2. The n-shaped reinforcement block 8 can limit the rack 35, so that the rack 35 is not easily offset on the outer side of the air inlet pipe 2, thereby successfully closing the slide groove 36.

[0034] See also Figure 1 A cover plate 91 is movably hinged on one side of the air inlet pipe 2 through a hinge, a first magnet block 92 is fixedly connected to one side of the cover plate 91, a mounting groove 93 is provided on one side of the air inlet pipe 2, and the air inlet pipe 2 is located inside the mounting groove 93 and is fixedly connected to a second magnet block 94. The cover plate 91 can seal the entrance of the air inlet pipe 2 by rotation, so that when the magnetic levitation blower 1 is not in use, foreign matter is not easy to enter the interior of the air inlet pipe 2, and the first magnet block 92 can be driven by the cover plate 91 to move into the interior of the mounting groove 93 and adsorbed with the second magnet block 94, which can enable the cover plate 91 to stably block the air inlet pipe 2 and prevent it from falling off.

[0035] The working principle and use process of the utility model are as follows: when using the device, first, the magnetic levitation blower 1 can take in air through the air inlet pipe 2, and the filter plate 31 inside the air inlet pipe 2 can filter and block foreign matter, so that it is not easy for large and small debris to cause the magnetic levitation blower 1 to be blocked and damaged. When the filter plate 31 is blocked after long-term use and needs to be dredged, the rotating rod 33 can be rotated first to drive the gear 34 to rotate, and the gear 34 will drive the rack 35 to move. At the same time, the rack 35 will drive the filter plate 31 to move inside the air inlet pipe 2 through the slider 37 until it is moved out of the air inlet pipe 2. At this time, the filter plate 31 can be cleaned and dredged. If the filter plate 31 is damaged, the bolt 42 can be rotated to disengage the threaded groove 43 to disassemble and replace the filter plate 31, and then the rotating rod 33 can be reversed to move the filter plate 31 back to its original position. At this time, the problem that the diameter of the air inlet pipe 2 is large, it is not easy to prevent some smaller items from being blocked when the air is taken in, and the blower is prone to damage over a long period of time can be solved.

[0036] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
