Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1:

[0023] Please see Figures 1-7 As shown, this utility model provides a detachable high and low voltage universal magnetic levitation blower, including a magnetic levitation blower unit 1, a main control unit 2, a latch 18, a surge port 21, and a transformer unit 3. The magnetic levitation blower unit 1 mainly includes a magnetic levitation motor 4, an impeller body 6, a volute 7, a guide impeller 12, a first air inlet 28, an air outlet 22, and a second cable passage 32. The main control unit 2 mainly includes a blower frequency converter 5, a blower control panel 8, a reactor 23, a main controller 20, a second air inlet 29, and a first cable passage 31. The transformer unit 3 mainly includes a transformer 27, a cooling fan 26, a third air inlet 30, and a third cable passage 33. The magnetic levitation motor 4 mainly consists of a stator 10, a rotor 11, a permanent magnet 13, an alloy sheath 14, a magnetic levitation motor housing 9, a front radial magnetic bearing 15, a rear radial magnetic bearing 16, and an axial magnetic bearing 17.

[0024] This technical solution solves the problems of traditional blowers being limited to low-pressure or high-pressure applications, being difficult to disassemble, being difficult and costly to convert from low-pressure to high-pressure, and requiring extensive modifications to the on-site power supply structure. It features simple disassembly, convenient maintenance, high flexibility, and strong reliability.

[0025] Example 2:

[0026] Based on Embodiment 1, this utility model is as follows: Figures 1-7As shown, there are ventilation openings between the magnetic levitation blower unit 1, the main control unit 2 and the transformer unit 3. The adjustable base 19 can be adjusted according to the actual position required by the transformer 27. The guide impeller 12 is connected to the non-drive end of the magnetic levitation motor 4. A first ventilation opening 24 is provided between the main control unit 2 and the magnetic levitation blower unit 1, and a second ventilation opening 25 is provided between the main control unit 2 and the transformer unit 3. The latch 18 is usually composed of a body and a latch pin.

[0027] Using the above technical solution, the gas drawn in from the air inlet flows into the magnetic levitation blower unit 1, and then through the impeller body 6, the gas is drawn into the volute 7. After being compressed inside the volute 7, the gas is generated into a fluid with a certain flow rate, pressure, and temperature, and then transported to the application environment. The base 19 facilitates installation and debugging by the user.

[0028] The working principle of this utility model is as follows: The magnetic levitation blower unit 1, the main control unit 2, and the transformer unit 3 are interconnected by ventilation openings. Air drawn in through the inlets flows into the magnetic levitation blower unit 1, and then through the impeller body 6, it is drawn into the volute 7. Inside the volute 7, the air is compressed, generating a fluid with a certain flow rate, pressure, and temperature, which is then transported to the application environment. The air inlets mainly consist of a first air inlet 28, a second air inlet 29, and a third air inlet 30, allowing a large amount of air at standard atmospheric pressure to be drawn into each unit. Internal ventilation openings allow external air to be drawn in. Intermittent air is transferred to the magnetic levitation blower unit 1. The transformer unit 3 cools the transformer structure through the cooling fan 26. The transformer unit 3 can be disassembled and reassembled with the main control unit 2 and the magnetic levitation blower unit 1 at any time according to the operating conditions without affecting the main structure of the blower unit, which is flexible and convenient. The adjustable base 19 of the transformer 27 can be adjusted according to the actual position required by the transformer 27, which is convenient for users to install and debug. Under high voltage conditions, the main control unit 2 supplies the low voltage AC power converted from the transformer unit 3 to the magnetic levitation blower unit 1 to meet the required power plant operating conditions. Under low-voltage conditions, Unit 2 does not require transformer Unit 3; power is directly introduced into the main control unit 2. After being filtered by reactor 23, the power enters the magnetic levitation blower unit 1. The main controller 20 controls the blower according to the operating conditions. The guide impeller 12 is connected to the non-drive end of the magnetic levitation motor 4. Through the rotation of the guide impeller 12, the air around the magnetic levitation motor 4 is circulated, which cools the motor. The magnetic levitation motor 4 compresses the gas in the impeller body 6 and the volute 7 and discharges it to the air outlet 22. A surge port 21 is provided to reduce overall vibration and noise. Under high-voltage conditions, the external cable enters the main control unit 2 through the first cable port 31, then enters the transformer unit 3 through the second cable port 32. The stepped-down 380V AC power enters the main control unit 2 through the third cable port 33. The control logic of the main control unit 2 enables coordinated control of the magnetic levitation motor 4. Under low-voltage conditions, the transformer unit 3 is directly disconnected. The external cable also enters the magnetic levitation blower unit 1 through the third cable port 33 after passing through the control logic of the main control unit 2, thus enabling control of the magnetic levitation blower and ensuring the integrity of the blower unit control structure.
