Description
Technical field
The present invention relates to a kind of ventilation fan.
Background technology
When not working, the air of ventilation fan both sides can also be circulated traditional ventilation fan by the gap between flabellum,
Therefore the effect for stopping mosquito can not be realized, more it is essential that when winter, bathing indoor ventilation fan becomes cold air
The passage of entrance, causes to bathe indoor temperature too low.To solve this problem, some ventilation fans, which add, is automatically closed air inlet
Function, its concrete technical scheme is that shutter is equipped with the outside of ventilation fan, and the window leaf of shutter is installed in shaft, need
When taking a breath, shutter is opened be rotated up the window leaf of shutter using the air-flow of ventilation fan, and need not taken a breath
When, the self gravitation of window leaf rotates down it and closes ventilation mouth.Above-mentioned ventilation fan is there are following problems, due to the weight of window leaf
Power is smaller, when the wind-force in the external world is larger, easily blows open window leaf, loses the effect of closing ventilation mouth, and in external air flow
Under the action of, window leaf can be opened and closed repeatedly, send irritating noise.
The content of the invention
The purpose of the present invention is to propose to the ventilation fan that a kind of air inlet can be automatically closed, this kind of ventilation fan can not work
When reliably close ventilation mouth.
The ventilation fan that the air inlet of the present invention can be automatically closed includes：
The fan body of frame-type, fan body center are equipped with ventilation mouth, and motor is provided with mouth of taking a breath and utilizes motor-driven flabellum；
Some gate leaves, the side of fan body are equipped with some rotation axis for being used to install window leaf, and window leaf can freely turn around rotation axis
It is dynamic；Window leaf is arranged in the prominent part of movable axis in the side away from rotation axis, the movable axis of fenestrate leaf be connected with connecting rod, the connecting rod
End be arranged in the prominent part of guide rod perpendicular to connecting rod, the fan body is equipped with the guide groove of arc, the end position of the guide rod
In in guide groove, the radius of the guide groove is equal to the spacing of rotation axis and movable axis on same window leaf, the center of circle of guide groove
Angle is 90 degree；The end of connecting rod is equipped with magnet；
Electromagnet, is made of iron core and the coil being wound on iron core, and the coil passes through ac-dc conversion circuit and ventilation fan
Power supply connection；Electromagnet is installed on fan body, and the lower end of face guide groove.
The course of work of above-mentioned ventilation fan is as follows：
After ventilation fan power-off is stopped, window leaf rotates down under the action of self gravitation around rotation axis, while passes through work
Moving axis drive connecting rod move down, connecting rod under the guiding role of guide rod and guide groove, can only along arc trajectory downwards and
The rear of fan body（I.e. indoor direction）It is mobile, until the magnet adsorption of interlinking lever end is on the iron core of electromagnet, at this time, window leaf
90 degree are have rotated around rotation axis, all window leaves cooperate, the same equivalent to shutter, close ventilation mouth.On connecting rod
The iron core of magnet and electromagnet is attached together, and connecting rod is fixed at the end position of guide groove, while makes window leaf can not be by
Extraneous air-flow is blown.
And after ventilation fan energization work, magnet spool obtains electric and produces magnetic, electromagnet and the magnet on connecting rod
Identical charges repel each other, and electromagnet is applied with repulsive force to the magnet on connecting rod so that the guide groove of connecting rod arcuately upwards, to fan body
Front is moved, so as to rotate synchronously and open with active window leaf, in addition, the air-flow that flabellum is formed can also blow flabellum, it is ensured that change
Gas port is opened.
Further, the upper and lower ends of the connecting rod are equipped with guide rod and magnet, so that the flabellum of upper and lower can
Smoothly open and close.
Further, the leading flank of the fan body is equipped with the boss for being used for limiting window leaf rotational angle, so that window leaf is closing
When closing, vertical angle is parked in just.
Further, in the window leaf, the section of middle part window leaf is parallelogram, the bottom surface and bottom of top window leaf
The top surface of portion's window leaf is inclined-plane, and so when window leaf is closed, the intersection of neighbouring window leaf is inclined-plane rather than level
Face, the bottom of eyebrow window leaf are pressed in the top end of lower part window leaf, and blowing to active force that indoor wind is applied can be by eyebrow window leaf
It is pressed on the window leaf of lower part so that window leaf more they tends to closed mode, it is ensured that window leaf will not be opened automatically under the action of external wind
Open.
The ventilation fan of the present invention passes through the installing connecting rods on window leaf so that the fenestrate leaf of institute can only rotate synchronously, and solve list
The problem of a window leaf is easily blown up；The electromagnet and magnet acted at the same time further through limiting rod, can close in window leaf
When for window leaf provide a relatively stable position-limiting action power, it is ensured that the stabilization of window leaf closed mode.
