See also Fig. 1, Fig. 2 and Fig. 3, be respectively among three-dimensional exploded view, three-dimensional combination figure and Fig. 2 of fast disassembly type fan of the present utility model sectional view along the A-A line.The utility model provides a kind of fast disassembly type fan, comprises stator 1, rotor 2 and protecting wire net 3; Wherein:

This stator 1 is constituted by the motor of fan, and can be provided with framework 10 in stator 1 periphery, is provided with fixed base 11 in the framework 10, is located on the fixed base 11 for stator 1 and is positioned at framework 10.

This rotor 2 is constituted by the flabellum of fan, comprise impeller 20 and two or more and be located in the outer blade 21 of this impeller 20, and have axially extended axle center 23, the impeller of being positioned at 20 centers, rotor 2 is hubbed on the said stator 1 by this axle center 23.As shown in Figure 3, in the present embodiment, described axle center 23 is fixedly arranged on the fixed base 11 of stator 1, and axle center 23 outer sheathed bearings 201, this bearing 201 is connected on the impeller 20 of rotor 2, sheathed again axle sleeve 110 outside this bearing 201 in addition, and 110 on this axle sleeve is fixedly arranged on the fixed base 11.In addition, as shown in Figure 4, in another embodiment, described axle center 23 is fixedly arranged in the impeller 20 of rotor 2, and the bearings 201 that are sheathed on outside the axle center 23 are fixedly arranged on the fixed base 11 with 110 on axle sleeves.

This protecting wire net 3 can be made by materials such as metal, plastics or plastic-steels, covers at above-mentioned rotor 2 tops, and can further be fixedly arranged on the above-mentioned framework 10.Protecting wire net 3 comprises central part 30 and the ventilation unit 31 around this central part 30; The ventilation unit 31 of the utility model illustrated embodiment is made of the concentric circle rigidity coil that two or more vary in size, has the effect of ventilation to form as structure as netted, protecting wire net 3 also is provided with two supports 310 in addition, this support 310 is by central part 30 radially oppositely extending along ventilation unit 31, by establishing assembly 33, pass two supports 310 respectively with further protecting wire net 3 is locked in 10 4 jiaos of default screws 100 in place of framework as spiral shells such as screws.

See also Fig. 1 again to shown in Figure 3, the utility model is mainly on impeller 20 end faces of rotor 2, be provided with first magnet assembly 22 in corresponding axle center 23, then be provided with second magnet assembly 32 in the central part 30 corresponding surfaces of protecting wire net 3 in addition, as shown in Figure 3, this second magnet assembly 32 is positioned at the top of this first magnet assembly 22, described first, two

magnet assemblies

22,32 with the corresponding setting of homopolar-repulsion mode, make rotor 2 energy by spacing with mutual expelling force towards stator 1 place by homopolarity magnetic, can and not contact with protecting wire net 3 maintenance spacings again simultaneously, can not produce the problems such as friction that cause because of contact.And the utility model for embodiment in, on impeller 20 end faces, be concaved with first groove 200, for described first magnet assembly, 22 build-ins in this first groove 200; In addition then be concaved with second groove 300 in central part 30 corresponding surfaces, for described second magnet assembly, 32 build-ins in this second groove 300.Described first and

second magnet assembly

22,32 can be respectively magnet.

Therefore, by above-mentioned contexture, can obtain fast disassembly type fan of the present utility model.

In view of the above, thereby fan of the present utility model can be assemblied in casing constitutes the casing with above-mentioned fast disassembly type fan of the present utility model, see also shown in Figure 5, fan of the present utility model can be installed on the positions such as radiation hole 40 as the casing 4 of computer or power supply unit, and can be by default locking hole 41, utilize spiral shell such as bolt to establish assembly 34 fan is locked on the casing 4.See also again shown in Figure 6,2 of the stator 1 of this fan and rotors except with axle center 23 as articulating, there is no technology or the means that any other fixed in hardware engages and exist, so when fan running, rotor 2 still can normally rotate; And when desire dismounting rotor 2, after only protecting wire net 3 need being unloaded, can in framework 10, take out rotors 2 easily, so that remove the dust on its impeller 20 and the blade 21, even after taking off rotor 2, just can be in framework 10 inboards are cleared up.

What deserves to be mentioned is: as shown in Figure 7, protecting wire net 3 also can lock or be directly molded on exhaust outlet 42 positions of casing 4, be not limited to be fixedly arranged on the framework 10, after only framework 10 need being taken off from casing 4 this moment, can remove the mutual expelling force that 32 pairs first magnet assemblies of second magnet assembly 22 produce, and then can rotor 2 be taken out easily for the user.In addition, as shown in Figure 8, described protecting wire net 3 also can constitute by two or more through holes are set on the plate body, and has a central part 30, and through hole herein promptly can be considered aforementioned ventilation unit 31, and can be cellular, to be located in around the central part 30, this second magnet assembly 32 is located on this central part 30.

Therefore,, utilize the principle of magnetic homopolar-repulsion, produce mutual expelling force, make fan on-stream, can keep the annexation that is pivoted that rotor 2 does not break away from stator 1 to push flabellum rotor 2 to motor stator 1 by fast disassembly type fan of the present utility model; And can be when rotor 2 decommissions, because of 2 of stator 1 and rotors except that articulating, do not have technology or the means that other fixed in hardware engages and exist, so can the confession user take off rotor 2 easily, reach the purpose of quick detach.

But the above only is a preferable possible embodiments of the present utility model, is not so limits to claim of the present utility model, so the equivalent structure that uses the utility model content to be done such as changes, all in like manner is included in the scope of the present utility model.
