Specific implementation mode
Below in conjunction with attached drawing, invention is further described in detail.
As shown in Figure 1, the embodiment of the present invention includes shell 1, particle detector 2, gas componant detector 3, environmental aspects
Detector 4, instruction device 5 and data processor 6, shell 1 include receiving portion 101, test section 102 and instruction unit 103.Inspection
Opening is provided in survey portion 102, particle detector 2 is arranged in test section 102, and detection particle is required to be passed through using part
Opening is in direct contact with air.The window of observation is provided in instruction unit 103, instruction device 5 is arranged in instruction unit 103,
It can be observed by user by window the part of instruction.Gas componant detector 3, ambient condition detectors 4 and number
It is arranged in receiving portion 101 according to processor 6.
As shown in Figure 1, the gas componant detector 3 of the embodiment of the present invention is arranged at the rear of particle detector 2.Particle is examined
Survey the air inlet being provided between device 2 and gas componant detector 3 for accelerating gas to be detected filling speed in receiving portion 101
Fan 7.Ambient condition detectors 4 are arranged between supply fan 7 and particle detector 2.Supply fan 7 is arranged in gas componant
The side of supply fan 7 is arranged in the front of detector 3, ambient condition detectors 4.Since particle is fixed in air, so most
It is easy to be led to the inaccuracy of detection by the barrier in structure, so particle detector 2 needs ingress of air at first, Bu Nengyou
Any barrier just can guarantee that the total number of particles entered in particle detector 2 is correct.And gas componant detector 3 is at one
It carries out sampling made testing result often in relatively small environment than carrying out sampling institute in a larger environment
The testing result made is accurate, because the distribution of pernicious gas may be non-uniform in larger environment, and gas componant is examined
The part that the relatively entire environment in part that device 3 can use indicates a very little is surveyed, error is caused to rise, and gas componant is detected
When device 3 is arranged in receiving portion 101, receiving portion 101 is formed comparatively small detection environment, and cooperation supply fan 7 moves
Gas equilibrium can be rapidly achieved by, which making, makes gas ratio in receiving portion 101 closer to the actual proportions in overall situation.But
Supply fan can cause the air on air-out direction to flow at work, this can be to ambient condition detectors 4 to humiture
Use interfere, so ambient condition detectors 4 can only be arranged in the side of supply fan 7, avoid air flow stream, promote inspection
Survey precision.The present embodiment is by causing reason to study the real work principle of each detector and the error of work
Obtain the above this spatial arrangement with logicality can reduce to the maximum extent due to structure design it is unreasonable caused by
Error increases the problem of generated function rather than those skilled in the art and goes to carry out sampling pair repeatedly using the algorithm of program
This cumbersome approaches of ratio go to solve the problems, such as function.
As shown in Figure 1, being provided with module fixed plate 8 in the receiving portion 101 of the embodiment of the present invention, module fixed plate 8 passes through
The card slot 104 being arranged on 101 inner wall of receiving portion is connect with receiving portion 101, and mainboard 9, mainboard 9 are additionally provided in receiving portion 101
It is attached by socket 10 with module fixed plate 8.Particle detector 2, gas componant detector 3, ambient condition detectors 4 with
And instruction device 5 is arranged in module fixed plate 8, data processor 6 is arranged on mainboard 9.It is additionally provided with USB on shell 1
Socket 11, USB jack 11 are connect with mainboard 9.This embodiment facilitates according to specific use demand and replaces different rule
The demand of the detector of lattice, while being also convenient for the operation to data processor 6 such as the export of data and the rewriting of programmed algorithm.
Particle detector 2 is PM2.5 dust sensors, specially DSM501A or same originals in the embodiment of the present invention
The dust sensor of reason.Gas componant detector 3 is that the formaldehyde of formaldehyde sensor CH20/S-10 or same principles senses
Device.Gas componant detector 3 or other special gas sensors simultaneously.Ambient condition detectors 4 pass for humiture
Sensor.Wherein humidity sensor uses humistor or Ceramic Humidity Sensor.Instruction device 5 is to pass through gradual change color indication
The led indicator lights of corresponding testing result can also directly be carried out numerical value or word etc. by liquid crystal display display screen and intuitively be exported.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the design of the present invention
It is defined with range.Under the premise of not departing from design concept of the present invention, technical side of the ordinary people in the field to the present invention
The all variations and modifications that case is made, should all drop into protection scope of the present invention, the claimed technology contents of the present invention,
Through all recording in detail in the claims.
