Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Please refer to fig. 1 and fig. 3, which are schematic structural diagrams of a magnetic suspension fan according to an embodiment of the present invention. Only the portions related to the present embodiment are shown for convenience of explanation.
Referring to fig. 1 to 3, a magnetic levitation fan 1 provided in an embodiment of the present application includes an annular stator 10, an electromagnetic coil 20 disposed concentrically with the annular stator 10, a fan blade 30 disposed in the electromagnetic coil 20, and a permanent magnet 40, where the permanent magnet 40 is disposed on the fan blade 30.
In one embodiment, the fan blade 30 has a vane 301 and a shaft core 302 fixed to the vane 301, and the permanent magnet 40 is disposed on the outer edge of the vane 301. In the present embodiment, the number of the lobes 301 is 3. In other embodiments, the number of lobes 301 may be adjusted according to product requirements.
In one embodiment, the permanent magnet 40 can be secured to the outer edges of the lobes 301 by a snap lock.
In an embodiment, the fan blade 301 is made of an aluminum alloy, an aluminum material, or a plastic material. The material of the fan blade needs to meet the requirement of strength in light weight. The lightness makes the overall mass of the fan blade 301 lighter, so that the loss of energy consumption for turning it is smaller.
In one embodiment, the magnetically levitated fan further comprises a housing (not shown) fixedly connected to the annular stator 10.
The annular stator 10, the electromagnetic coil 20, the fan blade 30 and the permanent magnet 40 which are concentrically arranged with the annular stator 10 are sealed and fixed through the outer cover, and the outer cover is designed to be a hollow structure, so that the generated wind can come out of the hollow structure when the magnetic suspension fan works.
Magnetic suspension fan is after the circular telegram, and annular solenoid 20 produces 360 degrees unipolar magnetism magnetic poles, for example S utmost point or N utmost point, permanent magnet 40 on fan leaf 30 with solenoid 20' S magnetism is opposite, forms opposite poles and attracts mutually, utilizes magnetic action to suspend the fan leaf in midair to make fan leaf 30 with do not have mechanical contact between the annular stator 10, neither can produce the noise and influence user experience, also can not have the problem that the loss of friction energy consumption influences product life.
Specifically, after the magnetic suspension fan is powered on, magnetic induction lines generated by the electromagnetic coil 20 are perpendicular to magnetic suspension lines generated by the permanent magnet 40, the fan blades 30 are parallel to the magnetic suspension lines generated by the permanent magnet 40, the weight of the fan blades 30 is fixed on a running track of the fan blades, and the whole fan blades 30 are suspended on the fixed running track by using a shaft core with almost no load to prop against the direction of the magnetic suspension lines, so that the fan blades 30 are not in mechanical contact with the annular stator 10. Therefore, the noise is not generated to influence the user experience, and the problem that the service life of a product is influenced by abrasion and energy consumption loss is avoided.
For current electric fan needs motor drive fan axle to rotate, produces noise and energy consumption loss easily, influences the problem that user experience feels and product life, this application embodiment utilizes the magnetic force effect of electromagnetic coil 20 after the circular telegram between with permanent magnet 40 for fan leaf 30 can directly suspend on the motion track, and drive the fan leaf rotatory, need not motor drive, and need not the fan axle, both saved the part cost, and make no friction between magnetic levitation fan axle and the bearing again, this application magnetic levitation fan embodiment overcome puzzlement tradition fan and produced the noise by motor drive, easy wearing and tearing between the part and influence product life scheduling problem, this application magnetic levitation fan has superior performance such as spin stabilization, no shake, the noise is low, high temperature resistant, product long service life, and do not have electrostatic discharge.
The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, without thereby limiting the scope of the invention. Any modification, equivalent replacement and improvement made by those skilled in the art without departing from the scope and spirit of the present invention should be within the scope of the claims of the present invention.
