There is provided a kind of blower fan of carpet cleaner, the bearing upside of blower fan for deficiency of the prior art by the present invention
Water proof ring is provided with to block bearing home record gap, prevents sewage from entering Bearing inner, it is to avoid the damage of bearing, further through at end
Setting tank is covered, largely can be barred from into the sewage in blower fan in tank, the sewage quantity entered in electric machine assembly is reduced,
Avoid causing water proof ring corrosion, effectively protect bearing, improve the service life of motor, reduce use cost.
Technical scheme will be clearly and completely described by embodiment below.Obviously, retouched
The embodiment stated is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, sheet
The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to the present invention
The scope of protection.
Please also refer to Fig. 1 to Fig. 3, as illustrated, a kind of blower fan of carpet cleaner, including set gradually from the bottom to top
Electric machine assembly, fan blade 5, end cap 6, movable vane wheel 7 and fan housing 8, electric machine assembly includes motor cover 1, motor 2 and rotating shaft 3, rotating shaft
Bearing 4 is provided with 3 output end.Movable vane wheel, fan blade are fixedly installed in rotating shaft, are synchronized with the movement with rotating shaft.
Motor cover 1, end cap 6 and fan housing 8 are removably secured successively, and the center of fan housing 8 is provided with air inlet 9, fan housing 8
Border is provided with air outlet 10, and rotating shaft drives dynamic wheel rotation to suck air and steam through air inlet, after thrown away from air outlet 10
Outside blower fan.
Proof mechanism of water is additionally provided with blower fan, proof mechanism of water includes the water proof ring 11 for being used to block the home record gap of bearing 4, with
And the tank 14 that being used on the upper surface of end cap 6 store suction sewage is taken shape in, water proof ring 11 is sheathed in rotating shaft 3 and is close to axle
Hold 4 upside settings.During work, rotating shaft 3 drives movable vane wheel 7 to rotate and carries out suction process to the foul water tank of cleaning machine, forms negative pressure,
Due to the difference of the inside and outside portion's pressure of foul water tank, sewage is sucked in foul water tank by the road, in water absorption course, a small amount of sewage steam
Blower interior can be sucked by air inlet 9, now, movable vane wheel 7, which rotates generation centrifugal force, makes most of sewage be thrown away through air outlet 10
Outside blower fan, part of contaminated water is interspersed among on end cap upper surface and is stored in tank 14, and small part sewage enters axle through the surface of rotating shaft 3
4 upsides are held, are stopped by water proof ring 11.
Water proof ring 11 is enclosed on rotating shaft 3 and is brought into close contact above with bearing 4, and is rotated with rotating shaft 3, by the home record of bearing 4
Gap is effectively sheltered from, load water proof ring 11 after, motor operationally water proof ring by sewage moisture barrier outside bearing, prevent water
Vapour enters bearing face, and bearing is hardly damaged, effectively the service life of extension cleaning machine, reduces use cost.
Tank 14 is the multiple annular concentric grooves being uniformly distributed on the upper surface of end cap 6.It is integral at each tank upper end-face edge
Form water retaining ribs 15.By setting tank and water retaining ribs mating reaction on end cap, water retaining ribs can be by liquid and water
Acid-base property solution keep off in the sink, prevent acid ＆ alkali liquid is flowed to from corroding water proof ring on water proof ring, improve water proof ring service life and
Protective capacities.
The outer wall of water retaining ribs 15 and the junction progress rounding processing with tank 14, make its overall streamlined structure,
Particle packing in sewage is avoided in junction, to facilitate the later stage to clean.
Fan housing 8 is connected and fixed with end cap 6, and movable vane wheel 7 is rotated and is arranged between fan housing 8 and end cap 6.Wherein, the edge of fan housing 8
Clamping side 16 is formed, the edge formation of end cap 6 has snap fit 17, and clamping side 16 is mutually matched with snap fit 17, facilitates the dismounting of blower fan
And install.
End cap 6 is provided with trim ring 13 at upper center position, and trim ring 13 is fixedly installed in rotating shaft 3, is synchronously transported with rotating shaft
It is dynamic.It is spacing to end cap progress by setting trim ring to realize, it is to avoid axial moving occurs in end cap.The size of trim ring is more than end cap central
The size in hole, plays certain effect of blocking to centre bore above it, reduces sewage steam and enters bearing by centre bore.Its
The quantity of middle trim ring can for 1 or be arranged in parallel it is multiple, be not limited specifically.
Bushing 12 is also compressed with water proof ring 11, bushing 12 is fixedly installed in rotating shaft 3.By setting bushing to press
Tight water proof ring, it is ensured that the tight fit between water proof ring and bearing.
The center-hole diameter of end cap is 13.5mm.Bushing 12 is located in the centre bore of end cap 6, and single between centre bore and bushing
Side gap is 0.5mm.The a diameter of 16mm of traditional end cap central bore, the unilateral gap between centre bore and bushing is 1.75mm, is led to
Cross and reduce above-mentioned size, to ensure that reduce soda acid liquid as far as possible enters bearing end by the gap between centre bore and bushing
Face, effectively protects water proof ring.
The invention discloses a kind of blower fan of carpet cleaner, including set gradually from the bottom to top electric machine assembly, fan blade,
End cap, movable vane wheel and fan housing, electric machine assembly include being provided with bearing, wind in motor cover, motor and rotating shaft, the output end of rotating shaft
Proof mechanism of water is additionally provided with machine, proof mechanism of water includes the water proof ring for being used to block the bearing home record gap, and takes shape in
Being used on end cap upper surface stores the tank of suction sewage, and water proof ring is sheathed in rotating shaft and is close to set on the upside of the bearing
Put.Water proof ring is enclosed on above rotating shaft to be brought into close contact with bearing, and is rotated with rotating shaft, and the home record gap of bearing is effectively blocked
Firmly, load after water proof ring, operationally water proof ring is by sewage moisture barrier outside bearing for motor, and prevention steam enters bearing end
Face, bearing is hardly damaged, effectively the service life of extension cleaning machine, reduces use cost.
By setting tank and water retaining ribs mating reaction on end cap, water retaining ribs can be molten by the acid-base property in liquid and water
Liquid is kept off in the sink, prevents acid ＆ alkali liquid is flowed to from corroding water proof ring on water proof ring, improves the service life and protective capacities of water proof ring.
In addition, by the way that end cap central bore size and bushing and center interporal lacuna are tried one's best minimum, farthest reducing
Acid ＆ alkali liquid enters bearing face and corrodes water proof ring.
