Description
Technical field
The present invention relates to a kind of fan structures, more particularly to a kind of novel drip-proof fan structure.
Background technique
When fan work, driven using motor of dust collector.Standard vacuum motor high speed rotation sucks empty from suction inlet
Gas makes dirt case generate certain vacuum, and dust enters the bag dust filter in dirt case by scrubbing brush, adapter tube, handle, hose, main suction pipe,
Dust is left in bag dust filter, and filtered air enters motor using one layer of filter, into motor air through motor
Outflow, and in the case where aqueous in dust impurity or dust catcher sucking water, because filter can not cross drainage, water is directly by dust catcher
Into motor, due to contained a large amount of impurities in sucking water with great corrosivity and water band it is conductive, water enters motor
Motor can be corroded in a short period of time afterwards, and the electric conductivity of water will cause electric motor short circuit leads to motor failure, or even burn.
In easily sucking moisture occasion, people use Wet-dry motor of dust collector, under the action of high-speed rotating movable vane wheel centrifugal force
By in air and foreign-body aspiration dust catcher, and Wet-dry dust catcher allows to suck when in use water, and water and air-flow meeting
By motor of dust collector air inlet sucking motor fan inside by fan cover air outlet outflow motor, but bad working environments be lauched with it is miscellaneous
Matter can penetrate into bearing chamber, and motor bearings failure is caused even to be penetrated into through bearing to motor due to water and impurity after long-term operating
Inside causes electric motor short circuit to burn, motor failure, serious curtailment motor useful life.
Motor inner conductor generates heating effect of current after being powered when motor operates, over time, the temperature of conductive surface
Degree constantly rises, and the temperature of motor is caused constantly to increase.Standard vacuum motor is the air draught that will suck by motor wind
Machine is directly entered motor, and air draught air while sucking dust impurity in dust catcher also cools down motor；It is dry
The principle of wet two-purpose dust collector motor be in the air draught that will be sucked and water and moisture impurity by Wet-dry motor of dust collector
Exclusion motor blower side dispersion or concentrated, and the motor other end cools down motor inner conductor equipped with cooling device, has
Body is that Wet-dry motor of dust collector rotor after the operating that is powered is run at high speed with 30000~50000rpm/min, rotor shaft
Upper that movable vane wheel is housed, movable vane wheel forms negative pressure in inducer and fan housing when telling operating, by air-flow with water and impurity by entering the wind
Mouth sucking excludes Wet-dry motor of dust collector by the air outlet for dispersing or concentrating, since the impurity in water and water has pole
Big corrosivity, motor bearings position, corrosion electrical motor can be flowed to impurities in water by electric motor end cap by being lauched in bad working environments condition
Bearing leads to motor failure, or even causes electric machine conductors short since water and impurities in water flow into inside motor through the gap of bearing
Road directly causes motor to burn failure.
Therefore, fan can accomplish waterproof but also the ideal not to the utmost that effectively prolongs the service life at present, need now find one kind
New technical solution solves the above technical problem.
Summary of the invention
The technical problem to be solved by the present invention is in order to overcome the defects of the prior art, now provide a kind of novel waterproof
Fan structure, air draught and impurities in water are sucked in motor fan housing and inducer by motor air inlet when motor runs at high speed,
Motor is discharged by air outlet, with motor run at high speed drip-proof fan centrifugal force effect under by the subtle water and impurity of entrance
It throws away, has prevented water completely and impurity enters situation inside motor bearings even motor, both realized the waterproof of fan structure
Function, and the service life of fan has been effectively ensured.
