Description
Technical field
The present invention relates to blower fan technical field, be especially a kind of blower fan inner rotor motor.
Background technology
Having a kind of blower fan inner rotor motor at present, it includes cast housing, plastic jacket and rotating shaft, cast housing and plastic jacket
Being axially mounted to together along rotating shaft, plastic jacket is provided with the through hole stretched out for roller end, and roller end is provided with for connecting wind
The whorl brace rod of wheel, whorl brace rod is used for axial lock wind wheel, and owing to said structure is only capable of, to reach IPx4 waterproof etc.
Level, so not being suitable for the use environment of requirement higher classification of waterproof requirement.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of blower fan using environment being applicable to requirement height classification of waterproof requirement
With inner rotor motor, thus ensure blower fan inner rotor motor performance in high classification of waterproof requirement uses environment.
The technical scheme is that, one blower fan inner rotor motor of the present invention, it includes cast housing, plastic jacket and turns
Axle, together with cast housing and plastic jacket are axially mounted to along rotating shaft, plastic jacket is provided with the through hole stretched out for roller end, turns
Shaft end is provided with the whorl brace rod for connecting wind wheel, and it also includes waterproof cover roller end covered, and waterproof cover sets
Having the first axial hole, the second axial hole passed for whorl brace rod, the end face of rotating shaft is provided through the axial of the first axial hole
Projection, whorl brace rod is arranged with the first isolation cushion, and a surface of the first isolation cushion fits with the outer end face of waterproof cover,
Another surface of first isolation cushion is provided with the equally distributed elastic of multiple circumference, and the outer surface of described waterproof cover is provided with week
To around second axial hole arrange annular the first guiding gutter, a plurality of the second guiding gutter being distributed radially, every second
One end of guiding gutter all connects with the first guiding gutter, and every second guiding gutter all extends to the edge of waterproof cover；
Described waterproof cover is truncated cone-shaped, and the inner top surface of waterproof cover is affixed with the end face of rotating shaft；
Waterproof cover is aluminium lid.
After using said structure, the present invention compared with prior art, has the advantage that due to blower fan internal rotor of the present invention
Motor is provided with waterproof cover roller end covered, and so, while not affecting motor self performance, enters waterproof cover
Row is waterproof, enables the classification of waterproof of the present invention to reach IPx6, so the present invention has is applicable to requirement height classification of waterproof requirement
The advantage using environment, thus ensure that blower fan inner rotor motor uses the performance in environment in high classification of waterproof requirement, with
Time the first isolation cushion can effectively intercept the vibrations of wind wheel, the elastic on the first isolation cushion can intercept the shake of wind wheel further
Dynamic, and guiding gutter is set on the lateral surface of waterproof cover and can effectively prevent water from flowing to the second axial hole, this blower fan internal rotor
When motor uses, aluminium lid is the most vertically placed, when water flows through from the second guiding gutter of the first guiding gutter upper end, and water inflow the
Then one guiding gutter is flowed out by the second guiding gutter of the first guiding gutter lower end so that water will not flow to the second axial hole, the most just
Make water cannot be introduced in motor, be more beneficial for the waterproof effect of the present invention.
The waterproof cover water guide of truncated cone-shaped faster, is more beneficial for the raising of water resistance of the present invention.
Aluminium lid is corrosion-resistant, and intensity is good, and service life is long, is more beneficial for the raising of present invention life-span and reliability.
As improvement, it is provided with the second isolation cushion between inner top surface and the end face of rotating shaft of described waterproof cover, so, has more
Good isolating affection, is more beneficial for the raising of present invention life-span and reliability.
