Abstract
The utility model discloses an exhaust-air fan, which comprises a housing, an electric motor, a wind blade and a bracket. The stator iron core, the coil, the magnetic circuit-separating chip as well as the short-circuiting ring of the electric motor are fixed in the center of the bracket. The rotor and an end of the rotary axle of the electric motor are fixed in the front bottom of the cylinder-style wind blade bracket. Thus, the electric motor is positioned inside the cylinder-style wind blade bracket when the electric motor is arranged completely by employing the connecting piece. Therefore, when the electric motor rotates, the radial running amplitude of the train axis is very small, which reduces the friction, but the rotating speed of the wind blade is relatively quicker and bigger, the power consumption becomes small, and the operational life span will then be prolonged. In addition, the built-in electric motor structure leads to the reduction of thickness of the whole exhaust-air fan. The utility model is nice in appearance, and can be widely applied.
Description
Technical field
The utility model relates to a kind of ventilating fan.
Background technique
Existing ventilating fan comprises case, support, and motor is fixed on the support, and fan blade props up to be located on the rotatingshaft that motor stretches out.The ventilating fan of this structure, during use, the radial-play of motor rotation axis is bigger, and friction is big, noise is also bigger, thereby rotating speed is slower, and air displacement is little, and power consumption is just big, and the radial-play of motor rotation axis is big, is easy to cause motor shaft to damage, and the working life of motor is shorter.
Summary of the invention
The purpose of this utility model provides that a kind of noise is little, air displacement is big, the ventilating fan of the long service life of motor.
The technical solution of the utility model is such: a kind of ventilating fan, comprise case, motor, fan blade and support, the stator iron core of above-mentioned motor, coil, magnetic by pass plate and short-circuited conducting sleeve are fixed in the above-mentioned support, one end of the rotor of above-mentioned motor and rotatingshaft is fixed on the above-mentioned fan blade, and the rotor of above-mentioned motor, rotatingshaft and stator iron core, coil, magnetic by pass plate, short-circuited conducting sleeve are assembled into a complete motor by link.
Above-mentioned fan blade comprises cylindric bearing and around the blade of being located on the cylindric bearing cylinder, one end of above-mentioned rotor and rotatingshaft is fixed in the inboard, preceding bottom surface of above-mentioned cylindric bearing, the other end then stretches to the back bottom surface of above-mentioned cylindric bearing opening, after the assembling, above-mentioned motor just is built in the cylindric bearing of above-mentioned fan blade.
A kind of ventilating fan of the utility model, stator iron core, coil, magnetic by pass plate and the short-circuited conducting sleeve of motor are fixed on the support, and an end of the rotor of motor and rotatingshaft is fixed in the inboard, preceding bottom surface of cylindric fan blade bearing, like this, by link motor is assembled when complete, motor just is built in cylindric fan blade bearing inside, thereby, the radial-play spoke degree of rotatingshaft was very little when motor rotated, reduced friction, thereby the rotating speed of fan blade is very fast, air displacement is also big, power consumption is just little, and then prolongs the working life of motor.And built-in electric machine structure makes the less thick of whole ventilating fan, and profile is more attractive in appearance, and Applicable scope is wider.
