The inner rotor motor is suitable for a use environment with a high waterproofing grade requirement, and the performance of the inner rotor motor for the fan in the use environment with the high waterproofing grade requirement is ensured.
Description
Technical field
The present invention relates to blower fan technical field, is specifically a kind of blower fan inner rotor motor.
Background technology
There is a kind of blower fan inner rotor motor at present, it comprises cast housing, plastic jacket and rotating shaft, cast housing and plastic jacket are axially assembled together along rotating shaft, plastic jacket is provided with the through hole stretched out for roller end, roller end is provided with the whorl brace rod for connecting wind wheel, whorl brace rod is used for axially locking wind wheel, because said structure only can reach IPx4 classification of waterproof, so be not suitable for the environment for use of the higher classification of waterproof requirement of requirement.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of blower fan inner rotor motor being applicable to the environment for use requiring high classification of waterproof requirement, thus ensures that blower fan inner rotor motor requires the performance in environment for use at high classification of waterproof.
Technical scheme of the present invention is, a kind of blower fan inner rotor motor of the present invention, it comprises cast housing, plastic jacket and rotating shaft, cast housing and plastic jacket are axially assembled together along rotating shaft, plastic jacket is provided with the through hole stretched out for roller end, roller end is provided with the whorl brace rod for connecting wind wheel, it also comprises waterproof cover roller end covered, waterproof cover is provided with the first axial hole, for the second axial hole that whorl brace rod passes, the end face of rotating shaft is provided with the axial projection through the first axial hole, whorl brace rod is arranged with the first vibration isolator, one 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, the outer surface of described waterproof cover is provided with the first guiding gutter of the annular that circumference is arranged around the second axial hole, many the second guiding gutters distributed radially, one end of every bar second guiding gutter is all communicated with the first guiding gutter, every bar second guiding gutter all extends to the edge of waterproof cover.
After adopting said structure, the present invention compared with prior art, have the following advantages: because blower fan inner rotor motor of the present invention is provided with waterproof cover roller end covered, like this, while not affecting motor self performance, waterproof is carried out by waterproof cover, classification of waterproof of the present invention is enable to reach IPx6, so the present invention has the advantage being applicable to the environment for use requiring high classification of waterproof requirement, thus ensure that blower fan inner rotor motor requires the performance in environment for use at high classification of waterproof, first vibration isolator effectively can intercept the vibrations of wind wheel simultaneously, elastic on first isolation cushion can intercept the vibrations of wind wheel further, and guiding gutter is set on the lateral surface of waterproof cover can effectively prevents water from flowing to the second axial hole, aluminium lid generally vertical placement when this blower fan inner rotor motor uses, when water flows through from the second guiding gutter of the first guiding gutter upper end, water is flowed into the first guiding gutter and is then flowed out by the second guiding gutter of the first guiding gutter lower end, make water can not flow to the second axial hole, also water is just made cannot to enter in motor, more be conducive to waterproof effect of the present invention.
As improvement, described waterproof cover is truncated cone-shaped, and the inner top surface of waterproof cover and the end face of rotating shaft are affixed; Like this, the waterproof cover water guide of truncated cone-shaped is faster, is more conducive to the raising of water resistance of the present invention.
As improvement, waterproof cover is aluminium lid, and like this, aluminium lid is corrosion-resistant, and intensity is good, long service life, is more conducive to the raising of life-span of the present invention and reliability.
As improvement, between the inner top surface of described waterproof cover and the end face of rotating shaft, be provided with the second vibration isolator, like this, there is better vibration isolating effect, be more conducive to the raising of life-span of the present invention and reliability.
