BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for analyzing water quality or properties of any liquid, mainly an aqueous solution.
[0002]
[Prior art]
Natural water includes rainwater, river water, lake water, groundwater, spring water, hot spring water, inorganic acid water, salt water, seawater, etc. On the other hand, there are naturally-derived products such as fruit juices from plants and squeezed juice from sap plants, and there are also liquids made by processing alcohol, vinegar, enzyme solution, etc. made by fermentation. Speaking of animals, there was milk, sheep and goat milk. There are various types of liquids, and until now, these liquids have been measured in the same way, and the analysis method to determine what kind of liquid the liquid is and what properties it has. There was no.
[0003]
For example, the physical properties of water include "specific gravity, density", "water vapor pressure", "boiling point", "evaporation heat", "heat of fusion", "specific heat", "thermal conductivity", "surface tension", "dielectric constant", and " The conventional measurement technology area includes “pH”, “redox potential”, and the like. Although the properties of the liquid to be measured can be analyzed by these measurements, the fact that the values of physical properties are the same does not mean that the liquids are the same. It was only a way to see an analytical aspect of the physical properties of these liquids.
[0004]
[Problems to be solved by the invention]
For example, it is extremely convenient to be able to determine what kind of liquid the liquid taken out in front of you is. In terms of water, it is a clean water, active water, and mineral water boom. If it is possible to determine whether the water brought out in front of the eyes is simply made by passing tap water through a water purifier or is valuable mineral water that is difficult to extract, it can be sold responsibly to consumers. Every human fingerprint is different. Each person can be identified by the fingerprint. Even if it does not go so far, it will be very useful in many ways if water can be discriminated depending on the type of water, the place of production, and the way it is processed.
[0005]
[Means for Solving the Problems]
Even with the same liquid, the frequency difference of the applied clock signal, unlike the phase difference between the transmission clock signal taken out after applying the clock signal and for applying a variable constant area was applied at any time interval It was found that a unique pattern was drawn for each liquid under the frequency signal. By using this technique, the pattern drawn for each liquid is different, and the liquid can be specified by looking at the pattern, thus solving the above-described problem.

DETAILED DESCRIPTION OF THE INVENTION
This will be described below with reference to the drawings. FIG. 1 is a basic block diagram for explaining a liquid property analysis method and a property analyzer according to the present invention. 2 is a variable frequency generating means, 4 is a liquid measuring section, 6 is a detecting means, 8 is a calculating means, and 10 is a display means. In this variable frequency generation means 2, for example , a signal having a frequency of 1 kHz is output from the output line 12 and the output line 14 at the beginning. Then, the frequency value is added and changed every 1 ms. Finally, a signal having a frequency of 4352 kHz is output in 4096 steps.
[0009]
The output clock signal is transmitted from the output line 14 to the first electrode 16, passes through the liquid to be inspected 5 of the liquid measuring unit 4, is taken out by the second electrode 18, and is sent to the input line 20. The original clock signal output from the variable frequency generating means 2 that is transmitted through the detection means in the 6 output lines 12 (pulse signal) detected by the detecting means 6 Both transmission clock signal transmitted through the input line 20 To do.
[0010]
Both the detected clock signals are compared and calculated by the calculation means 8. If the original clock signal sent from the output line 12 is an A signal and the transmitted clock signal sent from the input line 20 is an A ′ signal, the A ′ signal is delayed by passing through the liquid 5 to be inspected. To be precise, the more conductive impurities are in the liquid to be inspected, the more the resistance works and the longer the delay. Therefore, this delay is not the case with pure water. This change can be detected only by detecting a transparent clock signal sent from the input line 20 when grasping it as a change in voltage or current, but since the change value itself is extremely small, the A signal and A ′ The difference from the signal was taken to highlight only the change value, and fluctuations due to other factors were eliminated.
[0011]
This result is displayed on the display means 10. The display means 10 takes the frequency value that varies along the horizontal axis and the change value (voltage coefficient) along the vertical axis. FIG. 2 is a display example of a certain tap water (X ₁ and X ₂ ) drawn by the display means 10 as a result of such measurement. Although it is the same tap water, the state of the river basin and the middle of the river basin are different, and the state of industrial water and household wastewater flowing in is also different, so the solid line X ₁ and the broken line X ₂ are clearly different. Yes. As a result of the experiment, it was found that the same pattern was drawn for the same liquid when the same electrode material was used and the distance between the electrodes was the same, and the measurement was performed using the measurement method shown in FIG. It was confirmed that drawing different display patterns depending on the type of liquid and extracting the patterns were reproducible.
[0012]
The resistance value between the two electrodes 16 and 18 immersed in the liquid 5 to be inspected is considered as 1 / 2πfc1 when considered as a capacitor, and as 1 / 2πfL1 when considered as a coil. These combined a ₁ × 1 / 2πfc1 + b ₁ × 1 / 2πfL1 values become resistance values as liquids, and it is considered that a unique pattern for each liquid was created by taking into account resonance action by a specific frequency.
[0013]
Already using various liquids and repeating the measurement experiment according to the present invention, for example, liquor, vinegar, etc ... It has been found to show. Among them, if the patterns of genuine taste or standard products are organized and the computer recognizes the patterns, the quality of the newly measured liquid can be visually recognized.

Then, the holding portion 23 is slid downward to return the support base 22 to the original position, and the first electrode 16 and the second electrode 18 are inserted into the liquid 3 in the container 21 . These electrodes 16 and 18 have a diameter of 0.3 cm, for example, and are made of a brass base plated with gold to a length of 7 cm. The Each of these electrodes 16 and 18 s attached insulating film 26 and 28, without contact portion of the insulating film 26, for example, part of 2cm from one end is in contact with the liquid, otherwise to avoid contact is there. Also contains liquid 3 thus for soaking up portions of the insulating film over the contact portions, the contact portion of each of the two electrodes 16 and 18 facing each other are immersed in the liquid 3 and constant 2cm Become .
[0016]
A clock signal having a predetermined variable frequency is applied to the liquid 3 from the lead wire 32 connected to the output line 14 from the variable frequency generating means 2 in FIG. the receive transmission clock signal transmitted through the second electrode 18, transmission clock signal received is sent to the input line 20 of FIG. 1 via a lead wire 34 from the second electrode 18.
