Cigarette smoking.
Above-mentioned warning device 13 and speech player 2 collectively constitute warning system, when indoor smog concentration over-standard, the police
Various pieces in reporting system are simultaneously emitted by alarm and voice signal.
Preferably, Smoke Sensor 3 is arranged at the position of roof 15 of interior, and smog 1 is higher than indoor air temperature, the smog of high temperature
1 ramps up, therefore, and the position of roof 15 that Smoke Sensor 3 is arranged at into interior can more easily detect that indoor smog is dense
Degree.
It is further preferred that ventilation shaft 5 is also communicated in the roof 15 of interior, it is arranged such, can easily facilitates and utilize row
Indoor smog 1 is drawn into outdoor by gas fan 4.
In order to further improve the automaticity of public place ban on opium-smoking and the opium trade device, it is preferable that this programme is sensed in smog
Automatic control system is connected between device 3, exhaust fan 4, air exhauster 8, gas reflux apparatus 9 and warning system, specifically
Single chip computer automatic control system or relay automatic control circuit etc. can be used, those skilled in the art can be according to each portion
Part realizes that function carrys out the specific connection for setting all parts, repeats no more herein.
The course of work that this programme is discussed in detail in Fig. 2 is refer to below：
The indoor smokescope of detection, and judge the smokescope of interior whether beyond normal in real time of Smoke Sensor 3
Standard level, when someone's smoking in public place, indoor smokescope rises, and triggers Smoke Sensor 3, i.e. smog and passes
Sensor 3 judges that indoor smog is exceeded, now, and the exhaust fan 4 at the control ventilation shaft 5 of Smoke Sensor 3 two ends, air exhauster 8 are gentle
Body reflux 9 works, at the same time, and warning device 13 sends alarm signal, points out the keeper in Control Room 14 public
Someone's smoking in place, makes and gone before keeper prevention, also, the speech player 2 being arranged on indoor wall 16 also can be simultaneously
Work, plays the related ban on opium-smoking and the opium trade voice messaging such as " no smoking ".After exhaust fan 4 is by 1 suction ventilation pipeline 5 of smog, smog 1 is passed through
In the filter screen 6 and the adsorbent doped with activated carbon crossed in the middle of ventilation shaft 5, the adsorbable smog 1 of gas adsorbing device 7
The harmful substance such as carbon monoxide and nicotine.Smog 1 after adsorbed is pulled out ventilation shaft 5 by the air exhauster 8 at rear
Rear, by gas reflux apparatus 9, smog 1 is returned to after exhaust fan 4, smog 1 carried out using gas adsorbing device 7
Repeated multiple times absorption, it is therefore an objective to be fully absorbed the harmful substance in smog 1.The connected timing dress of gas reflux apparatus 9
Install and set circulation time (such as 3 minutes), after circulation time terminates, gas reflux apparatus 9 is stopped, after repeatedly adsorbing
Smog 1 be pulled out to outdoor by air exhauster 8.Now, indoor smokescope is reduced to normal level, Smoke Sensor 3
Stopping is triggered, and exhaust fan 4 and air exhauster 8 are stopped, and warning system is released therewith.
It should be noted that above-mentioned gas reflux 9 can also be connected to Smoke Sensor 3, when indoor smog concentration
It is reduced to after normal level, Smoke Sensor 3 can control gas reflux apparatus 9 to be stopped, it is not necessary to by timing means
Automatically controlling for gas reflux apparatus 9 can also be realized.
In summary, the utility model can realize the ban on opium-smoking and the opium trade one of the public place of the indoor environments such as market or public lavatory
Change control, from smoking is found to removing smoke removing and pernicious gas, then to the behavior for preventing smoker, truly realize public affairs
The ban on opium-smoking and the opium trade control in place altogether.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.A variety of modifications to these embodiments will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where not departing from spirit or scope of the present utility model.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
