Mostly research shows that PM2.5, PM10 cause significant danger to human health, especially respiratory system and the circulatory system in environment
Evil, and the forecast data of country PM2.5 only can only explain the air quality of monitoring station, indoor smoking, cooking, roadside community vapour
Situations such as tail gas is enriched with easily causes local PM2.5 concentration obviously to increase, for the susceptible personnel such as old man, infant, pregnant woman
For, the PM2.5 detections of specific environment are more crucial.Pass through the investigation to hand-held air quality detector product, Wo Menfa
Now a large amount of home equipment is moderate, but accuracy and consistency are often poor, it is difficult to meet testing requirements, and above-mentioned inspection
Surveying instrument does not have the function of collecting sample, can not carry out depth analysis to the ingredient and content of particulate matter.
As CN 201615883U disclose a kind of sensor of dust concentration, including dust passage and extraction fan, the powder
Dirt channel includes dust inlet channel and dust outlet passageway, and extraction fan is arranged in dust outlet passageway one end, dust air inlet
Channel is in horizontally disposed, and dust outlet passageway is arranged vertically, and dust is easy under the action of extraction fan and its its own gravity
It falls, will not be deposited in channel, ensure that the measurement accuracy of sensor of dust concentration.But the use of the device is by side
To limitation, it is necessary to which just can guarantee in dust outlet passageway vertical state will not deposit dust, cannot comprehensively and effectively solve powder
Dust sensor measurement accuracy problem.
To solve the above-mentioned problems, those skilled in the art are badly in need of a kind of air quality sample testing meter of hand-held, no
It is only capable of conveniently acquiring air sample and detects air quality data, and can guarantee the accuracy of detection data.
Invention content
The present invention provides a kind of air quality sample testing meter, can not only conveniently acquire air sample, can be with
Air quality data is detected, ensures the accuracy of detection data.

Air sample is acquired, air quality data can be detected, can be printed air regime data to sampler using flag member
The support plate upper surface at edge.When inverting air-blowing gear, air can be entered from air outlet slit, reversely purges entire air duct
And the sensor of detection air quality, play the role of clean air channel and sensor, ensures the standard of detector testing result
Exactness and consistency save the high calibration expense that detector needs calibration to be spent after a period of use.
Detector further includes gas control valve, and the gas control valve is between transfer tube and air outlet slit, the gas control
Valve processed includes test position and backwashing position, and when manually controlling gas control valve to test position, gear phase is evacuated with transfer tube
It is corresponding, it is corresponding with transfer tube air-blowing gear when manually controlling the gas control valve to backwashing position, it recoils in gas control valve
Position one end is equipped with air-filtering membrane.The gas control valve is connected to transfer tube, and air outlet slit is located at the valve body of gas control valve
End, the first situation, gas control valve are swivel tee valve, and one end is connected to transfer tube, and in addition both ends are test position respectively
And backwashing position, and it is equipped with air-filtering membrane in backwashing position one end, swivel tee valve includes valve body, valve chamber and handle, handle
Application valve body rotates in valve chamber, and when valve body closes one end of backwashing position, handle direct detection position, transfer tube is rotating forward
It is evacuated gear, air need to be detected and entered from air intlet, chamber, sampling cavity, transfer tube, are finally discharged by air outlet slit after testing,
Air sample is acquired under this state, detects air quality data;When valve body closes one end of test position, handle is directed toward recoil
Position, transfer tube need to detect air and enter from air outlet slit, through transfer tube, sampling cavity, test chamber, most in reversion air-blowing gear
It is discharged afterwards by air intlet, because being equipped with air-filtering membrane in backwashing position one end, passes through the cleaning of air-filtering membrane under this state
Air back flush air duct and sensor ensure accuracy and the consistency of detector testing result.
The air duct inner wall is equipped with not viscous grey coating, which prevents particulate matter to be adhered in air duct
Accuracy of detection is influenced on wall.Ash processing cannot not be done viscously in entire air duct inner wall, avoids the PM2.5 in air in sampling process
Equal particulate matters influence accuracy of detection because the reasons such as electrostatic are adhered to air duct inner wall, contribute to transfer tube back flush
Air duct.Specifically not viscous grey treatment process selection:Antistatic surface ingredient coating process, the coating work of water vapor condensation
Skill, mirror-polishing processing promote its finish.
The air duct is internally provided with an at least wake turbulence fan, the wake turbulence fan be located at air intlet to transfer tube it
Between air duct inside, prevent particulate matter remain in test chamber dead angle influence accuracy of detection.The wake turbulence fan is suspended on sky
Gas channel interior, is preferably provided inside test chamber, by the effect of transfer tube, need to detect air and be flowed in air duct,
Wake turbulence fan rotate as air flows, the need of agitation air channel interior detection air, makes air rotational flow, in air
Particulate matter be not easy to be adhered on air duct inner wall, ensure the precision of detector.
The air duct is equipped with the sampling pipe for extending to hull outside, which is connected with air acquisition head, the sky
Gas collection head is in the umbrella shape of inner hollow, and air intlet is uniformly distributed on air acquisition head outer surface, air acquisition head it is interior
Portion is hollow to be connected with test chamber.The sampling pipe is the extraneous sampling channel of connection, has elongated the sampled distance of air intlet, can
Go deep into special inside cavity, local inside cavity is detected air acquisition and carries out Detection of Air Quality, guarantee particular surroundings
Under accuracy of detection.To ensure that the detection air of acquisition belongs to a wide range of sample, it is not subrange sample, is set in hull outside
There is air collection head, which is circumferentially positioned at detector top, can be in umbrella, flat, cylindric, gengon
Shape etc., the inner hollow of the air acquisition head are connected with the test chamber of air duct, equal using air acquisition head surface
The air intlet acquisition testing air of even distribution, the structure design are conducive to air quality data stabilization, ensure accuracy of detection.
Described control unit further includes alarm module, on & off switch, power module, and the alarm module is received in control unit
When the air quality data that sensor detects reaches predetermined pollution numerical value, which sends out alarm;The switch
Key mapping is at the upper shell of shell, startup and stopping for controlling detector;The power module is located in the shell of shell
