(fourth embodiment)
The utility model fourth embodiment provides a kind of air supply device 2, as shown in Figure 1, air supply device 2 includes: shell
21, fresh wind port 22, air outlet 23, return air inlet 24, exhaust outlet 25, gas supply blower 26, exhaust blower 27, gas supply air-supply access
28, exhaust air-supply access 29.Detection device 1a/1b/1c is placed in gas supply air-supply access 28.
Composition about air supply device 2 illustrates that for details, reference can be made to the compositions of the air supply device in first embodiment, herein not
It repeats again.The course of work of air supply device will be illustrated next.
The course of work of air supply device: air supply device 2 is started to work, and outdoor air enters gas supply air-supply by fresh wind port 22
Access 28 flows into interior by air outlet 23, room air enters exhaust air-supply by return air inlet 24 and leads to by the processing of purification portion
Road 29 flows into outdoor by exhaust outlet 25.When needing to detect, air-valve motor 13 drives air-valve 12 to open air guide hole 15, air guide hole 15
Direction towards the gas supply air-supply hollow flow of air of access 28, air constantly enter the detection space of sampling box 11 and will test space
Interior original air is gradually discharged outside detection space；Each sensor that control unit 3 controls in sensor group 14 is prepared place
Reason, after detecting in space full of the air entered from gas supply air-supply access 28, air-valve motor 13 controls air-valve 12 and closes wind-guiding
Mouth 15, while the sensor in sensor group 14 detects the air in sampling box 11.
It should be noted that the sensor of sensor group starts to need to be prepared processing before detection, such as to sensing
Device is powered, and preheats its luminous or heat generating components in advance.In the course of work of detection device, if do not had in preparation processing
Air guide hole is closed when having completion, just will appear the test object object such as dust in the air before starting detection in detection space
Equal sinkages, test object object detects after sinking in order to prevent, causes testing result inaccurate, needs closing air guide hole
It is detected simultaneously, that is to say, that need to begin preparing processing in the front sensor for closing air guide hole, closing the same of air guide hole
When sensor complete preparation processing, sensor detected immediately.Time for preparing processing is pre-set, such as
The preparation processing time set, control unit 10s before closing air guide hole started each sensor in sensor group as 10s, closed
Prepare processing when closing air guide hole terminates just, and sensor enters detecting state.
