Background technology:
The anti-down cigarette device of tradition smoke exhaust ventilator generally is at the exhaust opening place valve to be opened/closed to be installed, and opens valve when smoke evacuation, then closes valve when not discharging fume, and utilizes valve will fall smoke shelf firmly, is the stifled cigarette mode of passive type; This device has two shortcomings, and 1, valve always has after closing the slit to exist, and when in the flue oil smoke being arranged, still can be dispersed into indoor by the valve slit; 2, after use a period of time, because oil stain attached on exhaust opening and the valve, makes its switching malfunctioning, thereby loses the effect of anti-down cigarette.
Summary of the invention:
The utility model provides a kind of air-exhaust type smoke exhaust ventilator to prevent the device of falling the cigarette, utilizes oil smoke to flow to from flue when indoor, can drive draft fan reverse rotation phenomenon lentamente, detects to have or not the situation of falling the cigarette, starts ventilating fan simultaneously and gets rid of cigarette.Bad sealing that has overcome the passive stifled cigarette of traditional anti-down cigarette device and occurred easily and the malfunctioning problem of control.
The utility model adopts following technical solution: by rotation direction sensor 7, draft fan 6, signaling interface 1, microprocessor 2, control interface 3, electric machine controller 4, fan electromotor 5 is formed the utility model, the induction end device of rotation direction sensor 7 detects turn signal on draft fan 6, signaling interface 1 one ends are connected with rotation direction sensor 7, the other end is connected with microprocessor 2 inputs, the turn signal of rotation direction sensor 7 outputs is converted to the signal that can discern and receive sends into microprocessor 2, microprocessor 2 output bus fall smoke signal through 3 pairs of control interfaces and drive and isolate, and connection electric machine controller 4 sends control signal, the control motor was with suitable rotation at a slow speed after electric machine controller 4 was received signal, to stop in the oil smoke inlet chamber, reached the purpose of anti-down cigarette.
Good effect of the present utility model is: install rotation direction sensor additional at exhaust opening, generation when falling cigarette fan keeps off oil smoke outside exhaust outlet with suitable rotation at a slow speed, reaches the purpose of anti-down cigarette, is active anti-down cigarette device.It is obvious that this installs anti-down cigarette effect, reliable working performance.

The specific embodiment:
According to shown in Figure 1, rotation direction sensor 7 output fans 6 turn signals are transported to microprocessor 2 behind signaling interface, when microprocessor 2 detects draft fan 6 counter-rotatings, just send smoke signal to electric machine controller 4 through control interface 3, the control motor was with suitable rotation at a slow speed after electric machine controller 4 was received signal, to stop in the oil smoke inlet chamber, so just reached the purpose of anti-down cigarette.The effect of signaling interface 1 is: the turn signal of rotation direction sensor 7 outputs is converted to the signal that microprocessor 2 can be discerned and receive; The effect of control interface 1 is: drive and isolate falling smoke signal, so that electric machine controller 4 can receive this signal and prevent that electric machine controller from disturbing microprocessor 2.
According to Fig. 2, present embodiment 1 adopts little magnetic patch and magnetic induction part 8 to constitute rotation direction sensor 7 as position sensor.A little magnetic patch 11 is fixed on the magnetic patch carrier 12, the magnetic patch carrier 12 is coaxial with fan 6, and rotate with fan 6, three magnetic induction parts 8,9,10 are distributed in around the magnetic patch carrier 12, when little magnetic patch 11 rotates with the magnetic patch carrier 12 can with three magnetic induction parts 8,9,10 overlap, magnetic induction part will send signal during coincidence, the signal output part of three magnetic induction parts connects the input of signaling interface 1, the output of signaling interface 1 meets the P10 of single-chip microcomputer 2, P11, P12, single-chip microcomputer 2 sends down smoke signal by P14, P14 is connected with the input of control interface 1, the control end of electric machine controller 4 is received in the output of control interface 3, and the output of electric machine controller 4 is connected with fan electromotor 5.
In Fig. 3, adopt angular displacement sensor as rotation direction sensor 7, microprocessor 2 is a single-chip microcomputer.The axle of fan 6 is connected with the incremental encoder rotor, drive the rotor rotation of incremental encoder during fan 6 rotation, when the encoder rotor turns clockwise, the leading B of encoder A road signal phase road signal then, when being rotated counterclockwise, the leading A of encoder B road signal phase road signal then.Signaling interface 1 is made of two latch and respective logic circuit, incremental encoder A road signal connects the input of latch A, B road signal connects the input of latch B, the output of latch A connects single-chip microcomputer T0 (input of timer/counter 0) pin, and the output of latch B connects single-chip microcomputer T1 (input of timer/counter 1) pin.When the pulse signal of the leading B of pulse signal phase place road, A road, signaling interface is the output output of A road pulse signal by latch A, and B road pulse signal is not exported, and the output of latch B does not have pulse output; When the pulse signal of the leading A of pulse signal phase place road, B road, signaling interface is the output output of B road pulse signal by latch B, and A road pulse signal is not exported, and the output of latch A does not have pulse output.
Single-chip microcomputer sends down smoke signal by P14, and P14 is connected with the input of control interface 3, and the control end of electric machine controller 4 is received in the output of control interface 3, and the output of electric machine controller 4 is connected with fan electromotor 5.
