The fan driven by the magnetic repellence is simple in structure, the cost can be reduced, and the utilization rate of electric energy converted into mechanical energy can be improved greatly.
Description
Technical field
The present invention relates to fan art, relate in particular to a kind of fan that drives by magnetic repellence.
Background technique
At present, the structure of conventional fan is generally by magnet, flabellum and a rotor of forming; The stator of forming by silicon steel plate, coil and bearing; And control circuit constitutes.The working principle of fan is that hot-wire coil is stressed and rotate in magnetic field, and electric energy mainly is converted into mechanical energy.But because coil has the effect of resistance, fan inevitably some electric energy will be converted into interior energy, the utilization ratio of electric energy is not high, and because parts such as motor, not only complex structure are installed in the flabellum, and increased the resistance that flabellum rotates, further reduce the utilization ratio of electric energy.
Summary of the invention
At above-mentioned defective, the technical problem that the present invention solves is to provide a kind of fan that drives by magnetic repellence, and is not only simple in structure, can reduce cost, and can improve the utilization ratio that is converted into mechanical energy of electric energy greatly.
In order to solve above technical problem, the fan that drives by magnetic repellence provided by the invention, comprise motor, framework and the flabellum of forming at base portion by at least two above vanes fixed, described flabellum by base portion rotating shaft and Bearing Installation on described framework, be fixed with on the described flabellum and decide magnetic, on the described framework motor is installed, be equipped with in the rotating shaft of described motor with described and decide the moving magnetic that magnetic matches, described moving magnetic is with described to decide the relative end magnetic pole of magnetic identical.
Preferably, described motor is installed on the described framework by support, is provided with pillar between described support and the described framework, and described pillar will be separated with one section space between described support and described framework.
Preferably, described to decide magnetic be more than two, describedly decides magnetic and evenly distribute on the same circumference of described flabellum, described moving magnetic and described to decide magnetic quantity supporting.
Preferably, describedly decide on the base portion that magnetic is installed in described flabellum.
Preferably, describedly decide magnetic and/or described to decide magnetic be magnet.
Preferably, described motor is a direct current generator.
The fan that drives by magnetic repellence provided by the invention is equipped with motor on the framework, be equipped with in the rotating shaft of described motor with described to decide the moving magnetic that magnetic matches, and described moving magnetic is with described to decide the relative end magnetic pole of magnetic identical.The principle that this fan utilizes the magnetic same sex to repel mutually drives moving magnetic and rotates when motor rotates, decide magnetic and begin rotation under the promotion of moving magnetic magnetic force, decides magnetic and then drive flabellum to rotate, and fan is started working.Compared with prior art, the fan that drives by magnetic repellence provided by the invention is owing to cancelled the parts such as motor that are installed on the flabellum base portion, not only make simple in structure, reduced cost, and flabellum when rotating friction reduce, improve the utilization ratio that is converted into mechanical energy of electric energy greatly.
Further, separate fully as the flabellum of rotating part with as the motor of power section in the fan that drives by magnetic repellence provided by the invention, promote flabellum by magnetic force and rotate, can accomplish separating of flabellum and motor.Therefore, this may be used on the environment that conventional fan can not be applied to by the fan that magnetic repellence drives, as in the water, oil is medium.

Embodiment
For those skilled in the art can understand technological scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
See also Fig. 1, Fig. 2, Fig. 1 is the structural representation of the fan that drives by magnetic repellence among the present invention; Fig. 2 is the decomposition texture schematic representation of the fan that drives by magnetic repellence among the present invention.
The fan that drives by magnetic repellence provided by the invention comprises direct current generator 1, framework 9 and is fixed on the flabellum that base portion 7 is formed by six blades 6, and flabellum passes through the rotating shaft of base portion 7 and Bearing Installation on framework 9.Two L shaped panel beatings 8 stick together by glue with two fixed magnets 10 respectively, and then are bonded at by glue on the base portion 7 of flabellum; Two L shaped panel beatings 8 are installed in base portion 7 edges, guarantee fixed magnet 10 alinements simultaneously.The framework 9 of fan is fixed with two pillars 4, and support 2 is fixed on the pillar 4 by screw 3, and pillar 4 is separated with one section space with support 2 and 9 of frameworks.Direct current generator 1 is installed on the middle part of support 2, installs in the rotating shaft of direct current generator 1 with long strip rotor 5, the two ends of rotor 5 are pasted with two moving magnets 11 that match with fixed magnet 10 by glue, and the end magnetic pole that moving magnet 11 and fixed magnet 10 are relative is identical.
Certainly, the fan that drives by magnetic repellence provided by the invention be supporting with two moving magnets and two fixed magnets be that example is done and illustrated and set forth technology contents of the present invention, in addition, the present invention can also be that a moving magnet and a fixed magnet are supporting, perhaps three above moving magnets and three above fixed magnets are supporting, can realize technical purpose of the present invention equally, not repeat them here.
See also Fig. 3, this figure is the fundamental diagram of the fan that drives by magnetic repellence among the present invention.The working principle and the process of the fan that drives by magnetic repellence provided by the invention are as follows:
The present invention is a principle of utilizing the magnet same sex to repel mutually.When direct current generator 1 rotates, drive moving magnet 11 rotations, fixed magnet 10 is in the promotion rotation of homo-polarity magnetic, when magnetic force can promote flabellum, the fan rotation of starting working.After direct current generator 1 outage, the gravity of flabellum overcomes magnetic force gradually, quits work.
Compared with prior art, the fan that drives by magnetic repellence provided by the invention is owing to cancelled the parts such as motor that are installed on the flabellum base portion, not only make simple in structure, reduced cost, and flabellum when rotating friction reduce, improve the utilization ratio that is converted into mechanical energy of electric energy greatly.
Further, separate fully as the flabellum of rotating part with as the motor of power section in the fan that drives by magnetic repellence provided by the invention, promote flabellum by magnetic force and rotate, can accomplish separating of flabellum and motor.Therefore, this may be used on the environment that conventional fan can not be applied to by the fan that magnetic repellence drives, as in the water, oil is medium.
Certainly, the above only is a preferred implementation of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
