Abstract
The utility model provides a four-in-one indoor air contaminant detector, belonging to the field of detection equipment. The four-in-one indoor air contaminant detector can detect hazardous substances generated due to indoor decoration through a lightweight and portable device. According to the four-in-one indoor air contaminant detector, control buttons and a display screen are arranged on a shell body, a detection module is mounted on the shell body, the edge of the detection module is provided with a circular and annular opening, the center of the detection module is provided with a colorimetric bottle hole, and a movable cover covers outside the detection module. According to the four-in-one indoor air contaminant detector, the problems are excellently solved by adopting a photoelectric color sensor, a colorimetric device (such as a colorimetric bottle) can be detected in a manner that the interior of the detector has no need of a monochromatic light source, and meanwhile, the photoelectric color sensor is adopted to carry out comparison for reagent paper strip colorimetry, so that the error is reduced. The four-in-one indoor air contaminant detector can detect the content of indoor contaminants, such as formaldehyde, benzene series, ammonia and TVOC (Total Volatile Organic Compound), in a simple and convenient, rapid and on-site manner.
Description
Technical field
The utility model belongs to the checkout equipment field.
Background technology
Formaldehyde (HCHO) is a kind of colourless molten irritative gas that is prone to; Formaldehyde can absorb through respiratory tract; Its WS " formalin " can absorb through alimentary canal, and the formaldehyde in the room air is mainly derived from the artificial boards such as scale board, core-board, medium density fibre board (MDF) and particieboard that are used for indoor ornamentation.Benzene is a kind of colourless liquid with special aromatic odor, and boiling point is 80.1 ℃, and toluene, xylene belong to substituted benzene; It all is the pyrolysis product of coal tar fractional distillation or oil; Benzene in the room air is mainly from using a large amount of chemical raw materials in the building decoration, like coating, and filler and various organic solvents etc.; All contain a large amount of organic compounds, behind finishing, evaporate into indoor.Ammonia is a kind of colourless and have the gas of intense stimulus property stink, and lta (proportion is 0.5) can feel that least concentration is 5.3ppm.Ammonia is a kind of alkaline matter, and it all has corrosion and spread effect to the skin histology of contact, and ammonia derives from the concrete admixture that uses in the building operation, mainly contains two kinds: a kind of is in the construction in winter process, in concrete wall, adds concrete antifreezer; Another kind is in order to improve concrete setting rate, to use high-alkali cement expansive material and early strength agent.TVOC is the abbreviation of TOVC.It comprises formaldehyde, benzene, to () (neighbour) xylene, styrene, ethylbenzene, butyl acetate, triclene, methenyl choloride, undecane etc.Interior architecture and ornament materials are the main sources of TVOC in the air.At present, on the market detection means of this pollutant generally all adopted the instrument or the test strips colourimetry of AAS.The instrument of AAS at first will have a stable monochromatic source, colorimetric device (like colorimetric bottle), detecting device.And other relevant supplementary measures will be arranged, could keep the consistance of instrument, more complicated.And the test strips colourimetry is easy to generate than mistake owing to adopt eyes and the colorimetric card comparison.
Summary of the invention
The purpose of the utility model provides a kind of objectionable impurities that indoor decoration is produced can unify the indoor air pollutants detectors through four of a light Equipment Inspection.
The utility model has control button and display screen on housing, detection module is installed on the housing, and the annulus opening is arranged on the edge of detection module, and there is the colorimetric bottle hole at the detection module center, and the detection module outside is covered with removable cover.
The utility model adopts the photoelectricity color sensor to solve above-mentioned problem well; Instrument internal does not need monochromatic source to detect by contrast colors device (like colorimetric bottle); Adopt the photoelectricity color sensor to compare to the test strips colourimetry simultaneously, reduced error.Can easy, quick, the on-the-spot content that detects indoor pollutant formaldehyde, benzene series thing, ammonia, TVOC.Instrument is the basis with the colorimetric analysis method, and the testing result intuitive is good.Large-screen lc shows, the man-machine interactive operation.Instrument adopts color detection module scheme, and modern design is easy to use.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
The utility model has control button 1 and display screen 2 on housing 3, detection module 4 is installed on the housing 3, on the edge 5 of detection module 4, annulus opening 8 is arranged, and there is colorimetric bottle hole 7 at detection module 4 centers, and detection module 4 outsides are covered with removable cover 6.
The utility model is based in the sample measured matter and behind extraction and cleaning, generates colored compound with the developer reaction, the instrument of a kind of colorimetric analysis that the principle that visible light is absorbed selectively according to this compound is set up.
When adopting photometry to detect, put into color detection module top annulus center to colorimetric device (like colorimetric bottle), get final product.
When adopting the test strips colourimetry to detect, test strips is put into color detection module top annulus opening part get final product.After detection finishes the color detection module lid is covered on the color detection module.
This instrument just can be worked under natural light.
The utility model principle of work: after testing begins; Colorimetric device (like colorimetric bottle) or test strips are placed on the color detection module, and the color sensor in the color detection module is sent to detection signal the concentration that can obtain material to be detected after the microprocessor processes.
Color sensor has adopted the integrated electro sensor, and the microprocessor major parameter is 8 single-chip microcomputers, internal storage 64K.The output signal that microprocessor is used for the receiving color sensor line data of going forward side by side is handled, and the information after the processing is shown by LCD MODULE.
Introduce the method for application of the utility model indoor air pollutants detector below in conjunction with concrete operations.
With for use after the chromogenic reagent preparation completion.
With putting into colorimetric device (like colorimetric bottle) after the preparation of gas absorption liquid; Put into color detection module annulus to colorimetric device (like colorimetric bottle) then; Drop in five of colorimetric devices (like colorimetric bottle) to chromogenic reagent then, start can show testing result.
The preparation of test strips is at first fetched blank test paper and is put into related reagent and soaked 20 minutes, treats that related reagent is dissolved in taking out behind the test paper fully to dry in the shade, and color detection module annulus opening is put in the airtight test paper barrel of packing into after the size shearing of test strips place, and is for use.
Doing when detecting, test strips is placed in color detection module annulus opening part, drop on the test strips one to chromogenic reagent then, start can show testing result.
