Problems solved by technology

[0007] Traditional ventilating fans are displayed visually by people, usually as fixed displays, and there are also rotating displays. The electric fan is supported by the full gravity of the booth, driven by electricity, which produces noise and consumes a lot of energy for long-term operation.

Embodiment 1

[0050] combine figure 1 , figure 2 , image 3 and Figure 4 Take the opening to closing process of the magnetic levitation ventilation fan of the present invention as an example. The working process of the maglev ventilation fan includes a fan opening process, a fan working process and a fan closing process.

[0051] When the fan is turned on, the power coil 3 and the balance coil 9 are energized and generate a magnetic field, and at the same time the limiting part is closed, and the suspension part 6 is under the influence of its own gravity G and the attractive force F of the first magnet 2. 1 And the magnetic field force F formed by the magnetic field generated by the balance coil 9 2 Under the action of the resultant force, it moves toward the fixed seat 8, and the floating part 6 generates a rotational movement during the movement toward the fixed seat 8, and the impeller speed of the floating part 6 is in the process of approaching the fixed seat 8. The reaction fo...

Abstract

The present invention relates to a magnetic levitation ventilation fan. When the magnetic levitation ventilation fan is in operation, the control unit provided on the first fixed part measures the emptying rate and air parameters obtained by measuring the real-time rotational speed information of the levitation part based on the rotational speed sensor. It is measured that the suspension part is subjected to the reaction force F3 of the air, the gravity G of the suspension part itself, and the attractive force generated by the first magnet on the first fixed part to the second magnet on the suspension part. F1 sets the current intensity through the balance coil in real time to generate a correspondingly changing magnetic field to form a force F2 on the levitation part and make the levitation part realize vertical direction under the condition of G, F1, F2 and F3 Force balanced and in suspension.

Description

technical field [0001] The invention relates to a magnetic levitation device, in particular to a magnetic levitation ventilation fan. Background technique [0002] Magnetic levitation technology refers to a technology that uses magnetic force to overcome gravity to levitate objects. The current levitation technologies mainly include magnetic levitation, light levitation, acoustic levitation, air levitation, electric levitation, particle beam levitation, etc. Among them, the levitation technology of magnetic levitation is relatively mature. Magnetic levitation technology (electromagnetic levitation, electromagnetic suspension) is referred to as EML technology (or EMS technology). There are many forms of magnetic levitation technology, which can be mainly divided into passive levitation in which the system is self-stabilizing and active levitation in which the system cannot be self-stabilizing. [0003] The system of magnetic levitation technology is composed of four parts: ...
