Brief description
Fig. 1 is that a kind of carbon dioxide of this utility model detects warning system module connection diagram.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become apparent from, below in conjunction with drawings and Examples, right
This utility model is further elaborated.It should be appreciated that specific embodiment described herein is only in order to explain this reality
With new, it is not used to limit this utility model.
As shown in figure 1, a kind of carbon dioxide detects warning system 100, intelligent absorption unit of dioxide carbon is when certain
Interior, room air is circulated, during air circulation, by the carbon dioxide absorption of in the air, by indoor dioxy
Change concentration of carbon to reduce；It include an air channel, be arranged on the first gas concentration lwevel transmitter 140 at this air inlet of air duct,
It is arranged on the carbon dioxide absorption assembly in the middle of this air channel and blower fan, the second gas concentration lwevel being arranged at ducting outlet become
Send device 150 and main control unit 120；Described main control unit 120 is believed with the first gas concentration lwevel transmitter 140 and blower fan respectively
Number connect；Described second carbon dioxide transmitter is in order to detect the dense carbon dioxide of out air after carbon-dioxide absorbent
Degree, described second carbon dioxide transmitter is connected with main control unit 120 signal, and described main control unit 120 is by the first carbon dioxide
