Embodiment
User is in the time cleaning carpet at present, and the blower fan part of motor can suck a large amount of addle, and the acid-base material in water can make motor bearings damage fast, reduces the working life of motor; Traditional motor structurally face also can play certain waterproof action, but effect is good not, in use still has a large amount of addle and flows to bearing the inside, causes bearing damage, and motor lost efficacy.
The utility model is for deficiency of the prior art; a kind of blower fan of carpet cleaner is provided, and the bearing upside of blower fan is provided with waterproof ring to block bearing home record gap, prevents that sewage from entering bearing inside; avoid the damage of bearing; by tank is set on end cap, the sewage entering in blower fan can major part be barred from tank again, reduces the sewage quantity entering in electric machine assembly; avoid waterproof ring to cause corrosion; effectively protection bearing, in the working life of improving motor, reduces user cost.
To be clearly and completely described the technical solution of the utility model by embodiment below.Obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
Please also refer to Fig. 1 to Fig. 3, as shown in the figure, a kind of blower fan of carpet cleaner, comprises the electric machine assembly, fan blade 5, end cap 6, movable vane wheel 7 and the fan housing 8 that set gradually from the bottom to top, electric machine assembly comprises electrical machinery cover 1, motor 2 and rotating shaft 3, is provided with bearing 4 on the output terminal of rotating shaft 3.Movable vane wheel, fan blade are fixedly installed in rotating shaft, are synchronized with the movement with rotating shaft.
Electrical machinery cover 1, end cap 6 and fan housing 8 are removably fixing successively, and fan housing 8 centers are provided with intake grill 9, and fan housing 8 borders are provided with exhaust outlet 10, and rotating shaft drives moving wheel rotation through intake grill air amount and steam, after throw away blower fan outside from exhaust outlet 10.
On blower fan, be also provided with waterproof mechanism, waterproof mechanism comprises the waterproof ring 11 for blocking bearing 4 home record gaps, and takes shape in and suck the tank 14 of sewage for storing on end cap 6 upper surfaces, and waterproof ring 11 is sheathed in rotating shaft 3 and is close to bearing 4 upside settings.When work, rotating shaft 3 drives 7 rotations of movable vane wheel to carry out suction process to the drain tank of washing machine, form negative pressure, due to the difference of the inside and outside portion of drain tank pressure, sewage sucks in drain tank by the road, in water absorption course, a small amount of sewage steam can suck blower fan inside by intake grill 9, now, movable vane wheel 7 rotates generation centrifugal force makes most of sewage throw away outside blower fan through exhaust outlet 10, part of contaminated water intersperses among on end cap upper surface and is stored in tank 14, and small part sewage enters bearing 4 upsides through rotating shaft 3 surfaces, is stopped by waterproof ring 11.
Waterproof ring 11 is enclosed within rotating shaft 3 and fits tightly with bearing 4 above, and with rotating shaft 3 rotations, the home record gap of bearing 4 is effectively sheltered from, pack into after waterproof ring 11, motor waterproof ring in the time of work is blocked in sewage steam outside bearing, stops steam to enter bearing face, and bearing is not fragile, effectively extend the working life of washing machine, reduce user cost.
Tank 14 is for being uniformly distributed in the multiple annular concentric grooves on end cap 6 upper surfaces.Each tank upper end-face edge place is one-body molded water retaining ribs 15.By tank and water retaining ribs mating reaction are set on end cap, water retaining ribs can be kept off the pH value solution in liquid and water in tank, prevents from that acid & alkali liquid from flowing on waterproof ring, to corrode waterproof ring, working life and the protective ability of raising waterproof ring.
The outer wall of water retaining ribs 15 and carry out rounding processing with the joint of tank 14, makes its entirety be streamlined structure, avoids particle packing in sewage in joint, to facilitate the later stage to clean.
Fan housing 8 connects and fixes with end cap 6, and movable vane wheel 7 rotates and is arranged between fan housing 8 and end cap 6.Wherein, fan housing 8 edges form clamping limit 16, and end cap 6 edges form snap fit 17, and mate mutually with snap fit 17 on clamping limit 16, facilitate dismounting and the installation of blower fan.
End cap 6 upper center positions are provided with trim ring 13, and trim ring 13 is fixedly installed in rotating shaft 3, is synchronized with the movement with rotating shaft.By arrange trim ring realize end cap is carried out spacing, avoid end cap occur axially collect together.The size of trim ring is greater than the size of end cap central bore, above it center hole is played to certain effect of blocking, and reduces sewage steam and enters bearing by center hole.Wherein the quantity of trim ring can be 1 or be arranged in parallel multiple, specifically do not limit.
On waterproof ring 11, be also compressed with lining 12, lining 12 is fixedly installed in rotating shaft 3.By lining being set to compress waterproof ring, ensure closely cooperating between waterproof ring and bearing.
The center-hole diameter of end cap is 13.5mm.Lining 12 is arranged in the center hole of end cap 6, and between center hole and lining, monolateral gap is 0.5mm.Traditional end cap central bore diameter is 16mm, and the monolateral gap between center hole and lining is 1.75mm, by reducing above-mentioned size, to ensure that reducing as much as possible soda acid liquid enters bearing face by the gap between center hole and lining, effectively protects waterproof ring.
The utility model discloses a kind of blower fan of carpet cleaner, comprise the electric machine assembly, fan blade, end cap, movable vane wheel and the fan housing that set gradually from the bottom to top, electric machine assembly comprises electrical machinery cover, motor and rotating shaft, on the output terminal of rotating shaft, be provided with bearing, on blower fan, be also provided with waterproof mechanism, waterproof mechanism comprises the waterproof ring for blocking described bearing home record gap, and take shape in and suck the tank of sewage for storing on end cap upper surface, waterproof ring is sheathed in rotating shaft and is close to the setting of described bearing upside.Waterproof ring is enclosed within above rotating shaft and fits tightly with bearing, and rotate with rotating shaft, the home record gap of bearing is effectively sheltered from, pack into after waterproof ring, motor waterproof ring in the time of work is blocked in sewage steam outside bearing, stops steam to enter bearing face, and bearing is not fragile, effectively extend the working life of washing machine, reduce user cost.
By tank and water retaining ribs mating reaction are set on end cap, water retaining ribs can be kept off the pH value solution in liquid and water in tank, prevents from that acid & alkali liquid from flowing on waterproof ring, to corrode waterproof ring, working life and the protective ability of raising waterproof ring.
In addition,, by by end cap central bore size and lining and center hole gap minimum as far as possible, farthest reduce acid & alkali liquid and enter bearing face corrosion waterproof ring.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to these embodiments' multiple amendment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
