The inner rotor motor for the air blower is applicable to environment with a high waterproof grade and guarantees the performance of the inner rotor motor for the air blower working in the environment with a high waterproof grade.

Description

A kind of blower fan inner rotor motor
Technical field
The utility model relates to the blower fan technical field, specifically is a kind of blower fan inner rotor motor.
Background technology
A kind of blower fan inner rotor motor is arranged at present, it comprises cast housing, plastic jacket and rotating shaft, cast housing and plastic jacket axially are assembled together along rotating shaft, plastic jacket is provided with the through hole that stretches out for roller end, roller end is provided with for the whorl brace rod that connects wind wheel, whorl brace rod is used for axially locking wind wheel, because said structure only can reach the IPx4 classification of waterproof, so be not suitable for the environment for use of the higher classification of waterproof requirement of requirement.
The utility model content
The technical problems to be solved in the utility model is a kind of blower fan inner rotor motor that is applicable to the environment for use that requires high classification of waterproof requirement to be provided, thereby to ensure the blower fan performance of inner rotor motor in high classification of waterproof requirement environment for use.
The technical solution of the utility model is, a kind of blower fan inner rotor motor of the utility model, it comprises cast housing, plastic jacket and rotating shaft, cast housing and plastic jacket axially are assembled together along rotating shaft, plastic jacket is provided with the through hole that stretches out for roller end, roller end is provided with for the whorl brace rod that connects wind wheel, it also comprises the waterproof cover that roller end is covered, waterproof cover is provided with first axial hole, second axial hole that supplies whorl brace rod to pass, the end face of rotating shaft is provided with the axial projection of passing first axial hole, be arranged with first vibration isolator on the whorl brace rod, one surface of the first shock insulation pad fits with the outer end face of waterproof cover, another surface of the first shock insulation pad is provided with a plurality of circumferential equally distributed elasticity posts, the outer surface of described waterproof cover is provided with first guiding gutter of the annular that circumferentially centers on the setting of second axial hole, many second guiding gutters that distribute radially, one end of every second guiding gutter all is communicated with first guiding gutter, and every second guiding gutter all extends to the edge of waterproof cover.
After adopting said structure, the utility model compared with prior art, have the following advantages: because the utility model blower fan is provided with the waterproof cover that roller end is covered with inner rotor motor, like this, when not influencing the motor self performance, carry out waterproof by waterproof cover, make classification of waterproof of the present utility model can reach IPx6, so the utlity model has the advantage that is applicable to the environment for use that requires high classification of waterproof requirement, thereby ensure the blower fan performance of inner rotor motor in high classification of waterproof requirement environment for use, first vibration isolator can effectively intercept the vibrations of wind wheel simultaneously, elasticity post on the first shock insulation pad can further intercept the vibrations of wind wheel, can prevent effectively that water from flowing to second axial hole and at the lateral surface of waterproof cover guiding gutter is set, the general vertical placement of aluminium lid when this blower fan uses with inner rotor motor, when water flows through from second guiding gutter on first guiding gutter, water flows into first guiding gutter and flows out by second guiding gutter of the first guiding gutter lower end then, make water can not flow to second axial hole, water can't be entered in the motor, more be conducive to waterproof effect of the present utility model.
As improvement, described waterproof cover is truncated cone-shaped, and the inner top surface of waterproof cover pastes mutually with the end face of rotating shaft; Like this, the waterproof cover water guide of truncated cone-shaped is faster, more is conducive to the raising of the utility model water resistance.
As improvement, waterproof cover is aluminium lid, and like this, aluminium lid is corrosion-resistant, and intensity is good, and long service life more is conducive to the raising of the utility model life-span and reliability.
As improvement, be provided with second vibration isolator between the inner top surface of described waterproof cover and the end face of rotating shaft, like this, have better vibration isolating effect, more be conducive to the raising of the utility model life-span and reliability.
