The wherein output control signal of controller 6, control signal when gas-detecting device 4 detects default pernicious gas,
Indicator 2 is set to swing between the original position of mark point 3 and the final position of mark point 3, final position is corresponding to be preset with
Evil gas concentration is more than the corresponding default harmful gas concentration of original position；The output alarm signal of controller 6, alarm signal is referring to
When showing the predeterminated position of the arrow mark point 3 of pin 2, control warning device 5 is reported to the police.
It should be noted that default pernicious gas can include：The pernicious gases such as toluene, formaldehyde, carbon monoxide.
Here, gas-detecting device 4 can detect one or more pernicious gas, generally sensor element.Work as gas
When detection means 4 detects various pernicious gases, multiple indicators 2 can be set, by different color or shape size etc. in addition
Distinguish, that is, different indicator correspondences indicates different pernicious gases.
It should be noted that mark point 3 is provided with default, but need not be excessive.
Preferably, mark point 3 can arrange three, to the concentration scale for dividing default pernicious gas, different dense of correspondence
Angle value.Specifically, the first mark point can be located at the original position of mark point 3, and the concentration of its pernicious gas is low, represent safety；The
Two mark points can be located at the point midway of mark point 3, and the concentration of its pernicious gas represents there is potential safety hazard up to exceeded critical；
3rd mark point can be located at the final position of mark point 3, and the concentration of its pernicious gas is high, represents dangerous.
Here, when the predeterminated position of the arrow mark point 3 of indicator 2, the output alarm signal of controller 6, control is reported to the police and is filled
Put 5 warnings.It should be noted that, predeterminated position one harmful gas concentration of correspondence, the harmful gas concentration is generally default setting, can
Be pernicious gas the corresponding position of concentration critical value, or pernicious gas concentration maxima position, certainly
It can be a certain position between critical value and maximum.
As shown in Figure 3, it is preferred that warning device to harmful gas may also include：Inside alarm housing 1, for receiving
The control signal, the stepper motor 7 for driving indicator 2 to swing, stepper motor 7 is electrically connected with controller 6.
Here, stepper motor 7 is connected with indicator 2, for the control signal for receiving to be converted into into corresponding angular displacement
Or the centrifugal pump of displacement of the lines, so as to drive indicator 2 to shift, that is, swing.It should be noted that harmful gas concentration
Difference correspondence controllers 6 produce control signals it is also different.
Preferably, warning device to harmful gas may also include：Inside alarm housing 1, for showing default harmful gas
The display screen 8 of bulk concentration value, display screen 8 is electrically connected with controller 6.
It should be noted that the concentration value transmission of the default pernicious gas that can detect gas-detecting device 4 of controller 6
To display screen 8, display screen 8 is set in real time to show the current concentration value of default pernicious gas.
Here, as shown in Fig. 2 being provided with transparent display screen baffle plate 9 corresponding with display screen 8 on alarm housing 1.This is saturating
Substantially display screen baffle plate 9 plays the effective protection to display screen 8, while being easy to user to read shown on display screen 8 being preset with
The concentration value of evil gas.
It should be noted that display screen 8 can show the concentration value of various pernicious gases, it is also possible to arrange multiple display screens
8 are used to show the concentration value of different pernicious gases.
Preferably, warning device to harmful gas may also include：Inside alarm housing 1, for indicating default harmful gas
The indicator lamp 10 of bulk concentration difference, the indicator lamp 10 is electrically connected with controller 6；Wherein the output indication signal of controller 6, indicates letter
Number when gas-detecting device 4 detects default harmful gas concentration value and reaches predetermined threshold value, make corresponding indicator lamp bright.
Here can illustrate, as shown in figure 3, three kinds of different colours indicator lamps, green indicating lamp, yellow indicator lamp and
Red led, electrically connects respectively with controller 6.Specifically, reach when gas-detecting device 4 detects default harmful gas concentration
During to the first predetermined threshold value, controller 6 exports the first indication signal, makes green indicating lamp bright；When gas-detecting device 4 is detected
When default harmful gas concentration reaches the second predetermined threshold value, controller 6 exports the second indication signal, makes yellow indicator lamp bright；When
When gas-detecting device 4 detects default harmful gas concentration and reaches three predetermined threshold values, the output of controller 6 the 3rd indicates letter
Number, make red led bright.
Here, the concentration of the pernicious gas of the first predetermined threshold value is low, represents safety；The pernicious gas of the second predetermined threshold value
Concentration represents there is potential safety hazard up to exceeded critical；The concentration of the pernicious gas of the second predetermined threshold value is high, represents dangerous.
Specifically, transparent indicator lamp baffle plate corresponding with indicator lamp 10 is provided with mark point 3.
It should be noted that while the control indicator lamp of controller 6 is bright, also can control indicator 2 and swing to correspondence instruction
The bright position of lamp, that is, at mark point 3.
Here, transparent indicator lamp baffle plate plays the effective protection to indicator lamp 10, while being easy to user's viewing lamp
State, so as to the state according to indicator lamp takes appropriate measures.
Specifically, indicator lamp 10 is Light-Emitting Diode, by the different resistance of resistance of connecting, realizes 6 pairs of differences of controller
The control of the light on and off of indicator lamp.
Preferably, warning device 5 is loudspeaker, is certainly not limited to loudspeaker, and other can play the device of warning effect
Can adopt.
It should be noted that the inside of warning device to harmful gas is additionally provided with power supply, for the inside of alarm housing 1
Appliance arrangement and components and parts are powered.
Preferential, the contour structures of alarm housing 1 of the present utility model are nose-shaped structure.Certainly, it is not limited to nose-shaped knot
Structure, other portable constructions, and the material of alarm housing 1 are not also limited.
