Reach radiator fan and cannot meet requirement on market, these outer rotor DC Brushless Motor radiator fan waterproof employing stator coils and
PCB electronic component vacuum coating or vacuum glue pouring technique, cost is high, complex process, and cannot reprocess；And outer rotor brush DC
Rotor magnetic steel and the magnet steel sheath of motor radiating fan process owing to the aequum ensureing operating is not suitable for doing waterproof processing, therefore
The magnet steel of outer rotor DC Brushless Motor cooling fan rotor and magnet steel sheath easily make moist rustization, cause outer rotor brush DC
The performance reliability of motor radiating fan declines, reduced lifetime.
Therefore, for the above, need prior art is reasonably improved.
Utility model content
For disadvantages described above, this utility model provides a kind of outer rotor DC Brushless Motor radiator fan water proof and dust proof dress
Put, make the stator coil within outer rotor DC Brushless Motor radiator fan, PCB electronic component, rotor magnetic steel and magnet steel sheath
Do not make moist, waterproof guarantee its performance and life-span, solve many deficiencies of prior art.
For achieving the above object, this utility model is by the following technical solutions:
A kind of outer rotor DC Brushless Motor radiator fan dust and water proof apparatus, including fixing seat, rotor shaft core, flabellum,
Ball bearing, bonnet, described fixing seat extends inward and forms a U-shaped circle cup with depression, described U-shaped circle cup interposition
Putting and manage to internal the extension in formation one of cup, fixedly mount stator module in this outside pipe, a step is extended in middle pipe inboard
And these step two ends are fixedly installed ball bearing, penetrate rotor shaft core inside described ball bearing and this rotor shaft core is stretched out
Part fixed installation flabellum outside ball bearing；
Set up at the rim of a cup of described U-shaped circle cup and increase by one between the rim of a cup of a bonnet and this bonnet and U-shaped circle cup
Seal gasket, flabellum loads armature spindle core inner and installs a sealing ring between this flabellum and adjacent ball bearing, sealing
Enclose and compressed to ball bearing by rustless steel card；Described middle pipe increases a cannelure towards the opening in flabellum direction, this
Cannelure is mutually inserted fixing with the annular ring of flabellum, and described flabellum is internal increases dust discharge blading.
Correspondingly, the internal diameter of described sealing ring and rotor shaft core external diameter are interference fit；Described rustless steel card external diameter with
Middle bore interference fit, described cannelure keeps a determining deviation with the annular ring of flabellum.
Having the beneficial effect that of outer rotor DC Brushless Motor radiator fan dust and water proof apparatus described in the utility model is right
High temperature, air humidity in the market demand are big, dust is big, have in the severe rugged environment of water and can normally use, this outer rotor direct current without
Brush motor radiating fan dust and water proof apparatus takes the internal structure sealed, and makes inside outer rotor DC Brushless Motor radiator fan
Stator coil, PCB electronic component, rotor magnetic steel and magnet steel sheath do not make moist, it is ensured that its performance and life-span.

Detailed description of the invention
As Figure 1-4, the outer rotor DC Brushless Motor radiator fan water proof and dust proof described in this utility model embodiment
Device, including fixing seat 11, rotor shaft core 21, flabellum 22, ball bearing 5, bonnet 6, described fixing seat 11 extends inward shape
Become the size of a U-shaped circle cup 1 with depression and this U-shaped circle cup 1 according to actual outer rotor DC Brushless Motor radiation air
Depending on fan, described U-shaped circle cup 1 centre position forms a middle pipe 2 to internal extension of cup, fixes outer rotor straight in this outside pipe 2
The stator module 3 of stream brushless motor radiator fan, a step 4 is extended in middle pipe 2 inboard and this step 4 two ends are fixedly installed
Ball bearing 5, described ball bearing 5 inside penetrates rotor shaft core 21 and this rotor shaft core 21 is stretched out outside ball bearing 5
Part fixed installation flabellum 22；
Correspondingly, set up at the rim of a cup of described U-shaped circle cup 1 bonnet 6 and this bonnet 6 and U-shaped circle cup 1 rim of a cup it
Between increase a seal gasket 7, it is internal and install between this flabellum 22 with adjacent ball bearing 5 that flabellum 22 loads rotor shaft core 21
One sealing ring 8, the internal diameter of sealing ring 8 and rotor shaft core 21 external diameter are interference fit, sealing ring 8 by rustless steel card 9 to rolling
Pearl bearing 5 compresses, rustless steel card 9 external diameter and middle pipe 2 internal diameter interference fit, so that outer rotor DC Brushless Motor radiation air
Fan the effect reaching water proof and dust proof when running well.
Correspondingly, described middle pipe 2 increases a cannelure 23 towards the opening in flabellum 22 direction, this cannelure 23 with
