Description of the Invention: [Technical Field] The present invention relates to a magnetic floating suspension fan, in particular to magnetic floating of a magnetic floating housing having an impeller by a magnetic floating principle. [Prior Art] Due to the faster processing speed of today's computers, the computer generates a large amount of waste heat. In order to make the waste heat quickly drain out of the computer casing, most of the fans are equipped with more fans to help Cooling. However, the vibration generated when the fan rotates causes the casing to resonate, so that other electronic devices mounted on the casing are affected by the vibration. In particular, a storage device such as a hard disk is extremely susceptible to the aforementioned vibration during operation, resulting in scratching of the hard disk by the read head, resulting in damage to the data and damage to the data. In severe cases, the hard disk is more likely to be damaged. It is a common practice to add a shock-absorbing design between the inside of the casing and the fan, for example, a gasket is added between the fan and the casing to buffer the vibration transmitted by the fan, but since the fan is still through the gasket and When the casing is in contact, the effect of damping is limited, and the damping effect cannot meet the requirements. Another method is to add a magnetic float between the impeller and the motor of the fan, but since the motor drives the impeller at a very high speed and the fan itself is locked to the casing, the vibration of the motor itself and the impeller rotate rapidly to drive The vibration generated by the airflow will still be transmitted to the casing. If the number of fans 201215775 is large, the minimum vibration requirement cannot be achieved. SUMMARY OF THE INVENTION In order to solve the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a magnetic floating fan device that is split into a fixed housing and a magnetic floating housing according to a housing of a general fan. A magnet early element is respectively disposed on the magnetic floating shell, and the magnetic housing is magnetically floated on the fixed housing by the repulsive magnetic force between the two magnets to prevent the vibration of the magnetic floating shell from being transmitted to the fixed housing. In order to achieve the above object, the present invention provides a magnetic floating fan device comprising: a fixed housing, a first magnet unit, a magnetic floating housing, an impeller, and a second magnet unit. The fixed housing can be attached to a fan frame that can be mounted to the housing or as part of the housing. The first magnet unit is disposed on the upper side of the fixed housing. The maglev housing is located above the stationary housing. The impeller is disposed inside the maglev housing. The second magnet unit is disposed on a lower side of the maglev housing and corresponds to the first magnet unit. When the first magnet unit and the second magnet unit are opposite to each other by the magnetic repulsive surface, the maglev housing is magnetically sequenced in the magnetic ocean direction. In summary, the magnetic floating fan device of the present invention utilizes the principle of magnetic levitation, so that the magnetic floating shell provided with the impeller does not directly contact the fixed housing and the fan frame, and can reduce most of the components compared with the prior art. Due to the vibration generated by the maglev housing, lower vibration requirements can be achieved. In addition, the user can install the magnetic floating fan device of the present invention on a general fan frame without changing the structure of the original fan frame to reduce the vibration inside the casing of the machine 201215775.
