Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of detection, warning, the full-automatic ventilation fan of ventilation, it comprises ventilating fan 1, also comprises:
The gas leak detector of forming by sensor 2, signal converting controller 3 and alarm 4;
The output terminal of described signal converting controller 3 also is connected with ventilating fan 1.
Below in conjunction with Fig. 1 Placement between ventilating fan and the gas leak detector is described.
The output terminal of sensor 2 is connected with the input end of signal converting controller 3, and the output terminal of signal converting controller 3 is connected with the input end of alarm 4 with ventilating fan 1 respectively.
Like this, when 4 work of signal converting controller 3 control alarms, control ventilating fan 1 work simultaneously, thereby indoor harmful gas is drained into outdoor.
Especially, also comprise gas-monitoring switch 5, the output terminal of described gas-monitoring switch 5 is connected with the input end of signal converting controller 3, and the output terminal of signal converting controller 3 is connected with the input end of sensor 2; Like this,, can signal be delivered to sensor 2 by signal converting controller 3 when gas-monitoring switch 5 is opened, thus 2 work of control sensor.Whether therefore, can select to control sensor by gas-monitoring switch 5 in running order.
Especially, also comprise ventilating fan switch 6, the output terminal of described ventilating fan switch 6 is connected with ventilating fan 1.Ventilating fan switch 6 is the control ventilating fans separately, can wait the work of independent control ventilating fan when needed like this and are not limited to when harmful gas is revealed.
As can be seen, the utility model will possess part at least, i.e. test section and do-part.
The test section is a sensor, can detect by sensor to reach certain density harmful gas;
Do-part is alarm and ventilating fan.
After the test section detects harmful gas,, receive conversion, control do-part work then by signal converting controller with regard to output signal.
If house-owner is in, can take measures, and this moment, ventilating fan was worked, and can not cause danger.After indoor harmful gas was deflated the fan discharge, sensor was less than harmful gas, so quit work by signal converting controller control alarm and ventilation fan.
If house-owner stays out, because ventilating fan is discharged indoor coal gas automatically, it is indoor to have avoided coal gas to be trapped in a large number, has eliminated potential safety hazard.
The utility model also should comprise control section, i.e. line switching, and line switching preferably has two, and one is used for controlling entire circuit, and another is used for controlling ventilating fan.The switch of control entire circuit is a gas-monitoring switch 5, and after connecting the 220V power supply, gas-monitoring switch 5 closures, thereby conducting entire circuit make whole device be in holding state, in case the gas leakage of detecting, ventilating fan, alarm be work at once just.The switch of control ventilating fan is a ventilating fan switch 6, and it only is used for controlling ventilation fan, when no gas leakage, and the ventilating fan switch 6 that closes, ventilating fan work can realize the function of conventional fan.
Preferably, above-mentioned gas monitoring switch 5 and ventilating fan switch 6 all are rotary switches, the advantage of have easy-to-operat, saving the space.Certainly in actual use, can change the switch of other form as required, as long as can realize any switch, all within protection domain of the present utility model to the control of circuit.
Preferably, described sensor 2 and alarm 4 all are fixed on the ventilating fan 1, have convenient processing, advantage simple, that save the space is installed.Be understandable that the position that sensor 2 and alarm 4 are fixed on the ventilating fan 1 does not need to limit, as long as can realize the combination of the two.Can be at the left side of ventilating fan sensor installation, alarm is installed on the right, also can location swap.Have some apertures 7 on the surface of ventilating fan, the contact of sensor installation below the hole, aperture can supplied gas pass through like this, makes things convenient for sensor; Can put protection net in the contact surface of sensor 2, protection net can avoid the contact of sensor 2 to be subjected to the pollution of oil smoke and dust, the sensitivity of assurance device.The bonnet of ventilation fan can be dismantled, and is convenient to the cleaning sensor contact.Alarm can be to be similar to the same shape of radio receiver loudspeaker, also has some apertures 7 on the ventilation fan surface of alarm front end, is convenient to sound during warning and spreads out of.
When ventilation fan described in the utility model is installed in indoorly when being used to monitor coal gas, described sensor is a gas sensor.Because the density of coal gas is littler than the air, should be suitably higher so install.For making its coal gas that better detects leakage, the position of installation is preferably in 1.5 meters scopes of source of the gas.But note ventilation fan to be installed in the gas ring top.
When sensor described in the utility model is carbon dioxide sensor, can be used for monitoring carbon dioxide, the ventilation fan of this moment can be used for the place that carbon dioxide such as basement, room, garage are easily assembled.
Replacing sensor described in the utility model is become other sensors to any gas sensitization, all can be used for monitoring this gas, for this purpose to use of the present utility model all within the protection domain of this patent.
In addition; present embodiment just is not the protection domain that limits it to illustrating of this patent; those skilled in the art can carry out the change of local techniques scheme to it according to scheme described in the utility model; in every case be to obtain without creative work according to the change that the described scheme of the utility model is done; all be considered as the replacement that is equal to this patent, all should be within the protection domain of this patent.
