Specific embodiment
In order to make those skilled in the art better understand the present invention program, below in conjunction in the embodiment of the present invention
Attached drawing, the technical scheme in the embodiment of the invention is clearly and completely described.
Embodiment 1
As shown in Figure 1-3, a kind of quantitative PH testing cassete based on smart phone, including shell 1, it is provided on shell 1 for putting
It sets the detection zone of PH reagent paper 2 and is symmetricly set on detection zone two sides for placing the colorimetric region of standard color comparison card 3, inspection
It surveys region to be parallel to each other with colorimetric region, detection zone includes the rectangle card slot 11 and visual windows 12 for having recess 13, can
The plastic, transparent piece 14 at least provided with a dripping hole 15 is provided on viewing window.Standard color comparison card is 1 ~ 14 extensive PH test paper mark
Quasi- colorimetric card is used for and 2 color of PH reagent paper is contrasted.Shell is plastic rectangular shell for fixing PH test paper and standard colorimetric
Card, dripping hole 15 are the hole of round hollow out, and in the top of PH test paper for test fluid to be added dropwise, the rectangle card slot 11 of recess 13 is
For placing PH reagent paper 2, wherein recess 13 is for taking out PH reagent paper 2, that is, PH reagent paper 2 is that have part
It is exposed to be convenient for changing PH reagent paper 2 outside shell 1.Smart phone is exactly that generally there are commonly the intelligence of camera function in life
Energy mobile phone, the inside is equipped with the APP of the automatic software for calculation of coloration, firstly, standard color comparison card and PH test paper are placed in testing cassete
In fixation position, prepare liquid is added drop-wise on PH test paper by dripping hole 15, after the discoloration of PH test paper, about 2s and standard colorimetric
Card comparison, taken pictures immediately with smart phone, when taking pictures, mobile phone testing cassete top 10cm or so, the top of mobile phone and
The top keeping parallelism of testing cassete makes testing cassete in the most middle position of mobile phone photograph picture, as far as possible in light when taking pictures as far as possible
It is not too dark and too bright place, calculates coloration automatically with software, realizes that pH value obtains accurate quantification interpretation.
In order to which comparison result is more accurate, standard color comparison card 3 includes acidic region, basic region and neutral region, plastics
Setting is there are three dripping hole 15 on slide 14, the position of three dripping holes 15 respectively with acidic region, basic region and in
Property region is corresponding.In actual operation, we often have certain understanding to detected substance, are all often to know this
Detected substance is acid, alkalinity or neutral, at this point, it is different detected substance can be respectively dropped into corresponding position
In dripping hole 15, in this way when taking pictures imaging contrast's color, the position in detection zone and colorimetric region is more closely, read
Numerical value it is also more accurate.In addition, the spacing between detection zone and colorimetric region is 0.5cm-1.0cm, distance too closely can be dirty
Standard color comparison card is contaminated, apart from too far, illumination condition has difference, and color difference can be obvious, and further, the aperture of dripping hole 15 is
Diameter 0.5cm is best, because the width of common PH reagent paper 2 is in 0.9cm or so, the aperture of the dripping hole 15 of 0.5cm can be located at
The middle position of visual windows.
In order to be more applicable for outdoor use, PH reagent paper 2 of the invention be it is band-like, it is band-like that storage is provided in shell 1

Or filter paper and moisture absorption layer 23 are Openworks shape.Briefly, band-like PH reagent paper 21 of the invention is to be stored in accepting regions, will
Band-like 21 initial segment of PH reagent paper is placed in the detection area and the end position of band-like PH reagent paper 21 is located at this in recess 13
Appearance, after the band-like PH reagent paper 21 in detection zone is used, it is only necessary to the reagent paper at recess 13 gently one is drawn,
The reagent paper being previously used is pulled out to the outside of shell 1, the part used is then fallen with tearing, is deposited in detection zone over there
Interior reagent paper be exactly it is new, can reuse so that it is convenient in replacement reagent paper, it is particularly convenient open air use.In addition, being
Make used PH reagent paper 2 will not pollution detection region, PH reagent paper 2 includes test paper layer 22,23 and of moisture absorption layer
Resin film 24, test paper layer 22 is for detecting and showing color change results, and moisture absorption layer 23 is for absorbing extra liquid, so that being detected
Liquid will not retain on the bottom plate of rectangle card slot 11, will not influence and detect next time, further, the bottom of test paper layer 22
Layer is provided with resin film 24, due to the water isolating of resin film 24, can give one layer more than the bottom plate of rectangle card slot 11 of guarantor
Shield.
In the present embodiment, accepting regions include storing shell 41a, the bracket 42 at the top of storage shell 41a, being located at bracket
The first roller bearing 431 on 42 is stored and is provided with windowing 44 on shell 41a, and the second roller bearing 432, band-like PH examination are provided in windowing 44
Agent paper 21 fold zigzag be accommodated in storage shell 41a in, that is, band-like PH reagent paper 21 fold back and forth be placed on storage shell
In 41a, one end of band-like PH reagent paper 21 by the second roller bearing 432 from being extended in windowing 44 outside storage shell 41a, using
First roller bearing 431 extends in rectangle card slot 11, when band-like PH reagent paper 21 passes through the first roller bearing 431 and the second roller bearing 432
When, it can guarantee that band-like PH reagent paper 21 for level, that is to say the band-like PH reagent positioned at the first roller bearing 431 and the second roller bearing 432
Paper 21 is smooth, to ensure that into that the band-like PH reagent paper 21 in rectangle card slot 11 is smooth.In addition, band-like PH
The end of reagent paper 21 is located at recess 13, and zigzag cutter is provided on recess 13, can make to be previously used so band-like
PH reagent paper 21 can quickly be torn.
