Background technology
At present, as the continuous development of society, the environmental consciousness of people are gradually strengthened, people want to air quality
Seek also more and more higher.Present Portable type room organic gas material (VOCs)/formaldehyde tables most of on the market are substantially all simply
Single sensor is equipped with, sensor directly contacts sampling, the more passive sample mode of category with environmental ambient air.Therefore,
In addition to the pollution concentration of surrounding enviroment, the air stream size of sensor proximity can also influence the signal that sensor receives, and hold
It is unstable to be easily caused reception signal, so as to impact analysis result.Meanwhile all indoor organic gas material on the market at present
In itself there is also instability problem, the sensor that the same same batch of brand is produced can all have differences sensor.This
A little reasons result in analysis result inaccuracy.
Utility model content
The utility model provides a kind of gas-detecting device, it is intended to solves technical problem existing for above-mentioned prior art, energy
Enough improve the accuracy of organic gas material concentration detection.
In order to solve the above technical problems, technical solution adopted in the utility model is：
A kind of gas-detecting device, including air storage chamber, gas input mechanism, gas output mechanism and two or more VOC are passed
Sensor, the gas input mechanism and gas output mechanism connect with air storage chamber, and the VOC sensors are arranged at air storage chamber
It is interior.
Preferably, the VOC sensors are three.
Further, in addition to control cabinet, the VOC sensors, gas input mechanism and gas output mechanism with control
Case processed is connected.
Preferably, the control cabinet is provided with display screen.
Preferably, the gas input mechanism and gas output mechanism are air pump.
Further, the air pump is certain amount of air pump.
Preferably, the control cabinet is additionally provided with alarm.
Further, the air storage chamber, gas input mechanism, gas output mechanism and VOC sensors are arranged at housing
It is interior.
It is using beneficial effect caused by above-mentioned technical proposal：The utility model passes through gas input mechanism and gas
Output mechanism makes gas storage indoor gas be in flow regime, and this active sample detecting is able to ensure that VOC sensors in air storage chamber
Do not influenceed by other external factors outside environment depollution source, so as to improve accuracy in detection；Passed simultaneously using several VOC
Sensor is detected simultaneously, and the multi-group data collected, which is averaged, to reduce inaccuracy caused by sensor difference itself,
Further improve the degree of accuracy of gas detection.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural representation for gas-detecting device that the utility model embodiment provides.
Embodiment
With reference to the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, a kind of gas-detecting device provided by the utility model, including air storage chamber, gas input mechanism, gas
Output mechanism and two or more VOC sensors, the gas input mechanism and gas output mechanism connect with air storage chamber, described
VOC sensors are arranged in air storage chamber.Gas storage indoor gas is made in flowing by gas input mechanism and gas output mechanism
State, this active sample detecting be able to ensure that VOC sensors in air storage chamber not by outside environment depollution source other are external
Factor influences, so as to improve accuracy in detection；Detected simultaneously using several VOC sensors simultaneously, the multigroup number that will be collected
Inaccuracy caused by sensor difference itself can be reduced according to averaging, further improve the degree of accuracy of gas detection.
Wherein, the VOC sensors can be selected three.For the unstability of VOC sensors in itself, to each batch
Sensor according to its data results do relatively to sort out, be divided into A, the class of B, C tri-;Respectively again by A, the sensing of the class of B, C tri-
One is respectively taken to be applied in the utility model in device, 3 VOC sensor sensings are pumped into the gas of air storage chamber, turn to electric signal
Each output, 3 sensors share 3 groups of data, take its mean values to calculate VOCs concentration, improve the accurate of detection according to this
Degree.
As further preferred scheme, in addition to control cabinet, the VOC sensors, gas input mechanism and gas are defeated
Go out mechanism with control cabinet to be connected.VOC sensors, gas input mechanism and gas output mechanism can be realized by control cabinet
Automatically control, while the detection numerical value of multiple VOC sensors can be calculated by average value by calculation procedure in control cabinet, and then
Intuitively draw on display screen on control cabinet, calculated without artificial, it is directly perceived quick, while also reduce and calculate wrong probability.
In a preferred embodiment of the present utility model, the gas input mechanism and gas output mechanism are gas
Pump.Certain amount of air pump can be selected in air pump used, the air-flow into air storage chamber is kept quantitative disengaging by two certain amount of air pumps,
Using a quantitative pumping ambient air to air storage chamber, another will be pumped into air storage chamber and has made the gas pump of data analysis
Go out, realize the flow detection of gas storage room air.By peripheral quantitative air in certain amount of air pump pumping surrounding air to air storage chamber
Perform an analysis output data to VOC sensors, then walked by another certain amount of air pump pump, so circulation.
In a specific embodiment of the present utility model, the control cabinet is additionally provided with alarm, can according to being actually needed
The setup parameter value in control cabinet, when gaseous contamination degree reaches the parameter value upper limit, that is, alarm is sent, prompt gaseous contamination to surpass
Mark.
In order to facilitate carrying, air storage chamber, gas input mechanism, gas output mechanism and VOC sensors can be arranged at
In housing, joint and display screen are correspondingly arranged on housing, it is convenient to connect power supply and observation data.
In summary, the utility model has the advantages of simple in construction, easy to operate, gas accuracy in detection is high, passes through
Two certain amount of air pumps realize that flowing gas state is detected in air storage chamber, and air storage chamber is pumped into using three VOC sensor sensings
Gas, turns to electric signal and each exports and obtain 3 groups of data, takes its mean values to calculate VOCs concentration, and sensor is poor in itself
Inaccuracy reduces caused by different, VOC sensors is not influenceed by other external factors outside environment depollution source, further carries
The degree of accuracy of high gas detection.
Many details are elaborated in superincumbent description in order to fully understand the utility model, but this practicality is new
Type can also be different from other manner described here using other to be implemented, and those skilled in the art can be without prejudice to this reality
With doing similar popularization in the case of new intension, therefore the utility model is not limited by particular embodiments disclosed above.
