The utility model enters carbon monoxide transducer from collection port by the ventilation hole ventilating air from shell, air,
If containing carbon monoxide in air, carbon monoxide transducer issues electric signal and controls the circuit of power supply and alarm.If an oxygen
Change concentration of carbon is higher, then what carbon monoxide transducer issued is higher than preset threshold electric signal, receives and senses from carbon monoxide
The relay of device signal then connects the circuit between power supply and alarm, promotes alarm work.When carbonomonoxide concentration reduces
When, the electric signal that carbon monoxide transducer issues dies down, and is lower than preset threshold, receives from carbon monoxide transducer signal
Circuit between relay auto power off and alarm realizes being automatically closed for alarm.
Carbon monooxide alarm device is integrated on car key by the utility model, when not using automobile, is taken away with personnel,
Avoid sensitivity and the service life of the gases affect carbon monooxide alarm device in automobile.Start since starting automobile needs key
Or control, when driver enters automobile, interior carbonomonoxide concentration can be detected, remove artificial actively starting inspection from
Step is surveyed, the safety accident for forgetting detection operation and appearance is prevented.In addition, while the car is driving, carbonic oxide alarming dress
Setting can be with the concentration of complete monitoring car carbon monoxide, timely warning reminding.
Further, above-mentioned ventilation hole is in horn-like, and the first port of ventilation hole is located at the outer surface of shell, ventilation hole
The connection of the collection port of second port and carbon monoxide transducer, the bore of first port are greater than the bore of the second port.
The utility model is easier ventilating air in horn-like ventilation hole, makes the detection of carbon monoxide much sooner.This
Outside, ventilation hole is single hole, it is easier to be blocked, after alarm equipment alarm, can block ventilation hole manually, terminate alarm work
Make.
Further, above-mentioned power supply is the battery of key body.
When the key body and carbon monooxide alarm device of the utility model share a power supply, car key can be improved
Globality.
Further, above-mentioned power supply is independent current source and the inside that shell is arranged in.
When the carbon monooxide alarm device of the utility model uses independent current source, key body and carbon monoxide can be extended
The respective service life of warning device.
Further, above-mentioned power supply is button cell.
Further, above-mentioned shell is equipped with display lamp, and display lamp is electrically connected to a power source.
Further, multiple apertures are equipped on the above-mentioned shell and position of corresponding alarm.
Further, above-mentioned carbon monoxide transducer is electrochemical carbon monoxide sensor.
Electrochemical carbon monoxide sensor has good linear measurement range and very high selectivity, anti-cross-over gases
Interference performance is also very strong, and is zero-power type, without heating.
Further, the quantity of above-mentioned carbon monoxide transducer is that 2,2 carbon monoxide transducers pass through relay respectively
It is connect with alarm.
The utility model has the following beneficial effects:
(1) carbon monooxide alarm device is integrated on car key by the utility model, do not use automobile when, with personnel with
It walks, avoids sensitivity and the service life of the gases affect carbon monooxide alarm device in automobile.
(2) start or control since starting automobile needs key, when driver enters automobile, the utility model
Carbon monooxide alarm device can detect interior carbonomonoxide concentration, remove from and manually actively start detecting step, prevent
The safety accident forgetting detection operation and occurring.
(3) while the car is driving, the carbon monooxide alarm device of the utility model can be with complete monitoring car one
The concentration of carbonoxide, timely warning reminding.
It (4), can be with one of space locating for real-time detection carrier since car key can be easy to carry and can carry
The concentration of carbonoxide, timely warning reminding.
