Specific implementation mode
The embodiment of the utility model is described in detail below with reference to accompanying drawings and embodiments, whereby to the utility model
How applied technology method solves technical problem, and the realization process for reaching technique effect can fully understand and implement.
If it should be noted that do not constitute conflict, each feature in each embodiment and each embodiment in the utility model
It can be combined with each other, be formed by technical solution and both be within the protection scope of the present invention.
It is illustrated by taking m=4 as an example, 4 water quality detection chambers 3 are respectively used to TDS detections, pH detections, colorimetric detection and turbid
Degree detection.Chemical agent and medicament carrier needed for corresponding detection project are placed in advance in 4 water quality detection chambers 3 respectively.
First, the tap water (water sample) that tap flows out is poured into sampling of water quality from the head cover water inlet of sampling of water quality chamber 2
Chamber 2, water sample are separately flowed into through 4 tubules 6 in 4 water quality detection chambers 3, water sample and the chemical agent and medicine in water quality detection chamber 3
Agent carrier reacts, and stands.
Organic matter to be checked in water is reacted with chemical agent, and makes different feedbacks.
TDS is detected：TDS is the abbreviation of English total dissolved solids, and Chinese translation is that the solid of dissolving is total
Amount, units of measurement are mg/litre (mg/L), it shows in 1 liter of water dissolved with how many milligrams of dissolved solids.It include inorganic salts and
The total amount of organic matter.By detecting total dissolved solid, you can analyze the total salinity of water quality, and measuring principle is actually
By measuring the conductivity of water to reflect TDS values indirectly.For in the physical sense, dissolved matter is more in water, the TDS of water
Value is bigger, and the electric conductivity of water is also better, and conductivity value is also bigger.
PH is detected：For detecting hydrogen ion concentration in measured object and being converted into corresponding electric signal output.
Colorimetric detection：Coloration is caused jointly by suspension substance, colloid karyolysis substance, and qualitative description is generally used
Mode.Water sample stands clarification after entering water quality detection chamber 3, and sensor 7 sends out detection light beam to water sample and receives through water sample
The reflected beams, and convert optical signals into electric signal and be sent to control unit 4, the reflected beams of reception include the coloration letter of water sample
Breath, different Pt-Co color ranges correspond to different value of electrical signals.
Turbidity measurement：Turbidity be caused by the suspended particulate in water, suspended particulate can diffusing reflection incident light, scattering light with
Turbidity meets multistage linear relationship.Testing principle is that sensor internal is the infrared mutual-tube of an IR958 and PT958 encapsulation,
When light passes through a certain amount of water, the transit dose of light depends on the dirty degree of the water, and water is more dirty, and the light of transmission is got over
It is few.The luminous intensity of transmission is converted to corresponding size of current by optical receiving end, and the light of transmission is more, and electric current is big, otherwise the light penetrated
Few, electric current is small.The value of electrical signals of different dirt degree outputs is different.
Water sample in above-mentioned 4 water quality detection chambers 3 through standing after a period of time, and after enabling it fully react, it is single to start control
Member 4 works, and control unit 4 includes the identical control circuit of four groups of structures, and four control circuits are corresponding, receive 4 biographies respectively
The electric signal that sensor 7 is fed back, and be respectively processed.
It is illustrated so that TDS detects corresponding control circuit as an example, the electric signal of TDS sensors output is sent to amplifier A
In-phase input end, the inverting input access of amplifier A is reference electrical signal, when being more than the reference electrical signal, amplifier A output
High level, LED2 is bright, and LED1 goes out, exceeded to characterize TDS.Conversely, the electric signal of TDS sensors output is less than reference electrical signal
When, amplifier A exports low level, and LED1 is bright, and LED2 goes out, not exceeded to characterize TDS.The size of the reference electrical signal is obtained by R2 adjustment
?.
The principle of others detection control circuit is identical, and respective reference signal is different, by respective control circuit
R2 adjusts to realize.
Portable water quality detector provided in this embodiment, a length of 8 centimetres, width be 4 centimetres, it is 4 centimetres a height of, it is small
Ingeniously, easy to carry, it can realize quick detection, convenient and efficient, visual result is illustrated, and residential households can be used.
