[0025] The acid-base concentration analyzer with temperature regulation function of this embodiment adopts a temperature control component to generate a high-temperature airflow or a low-temperature airflow to enter the temperature control tube 8, and regulate the temperature of the temperature control cavity 7, thereby controlling the temperature of the containing chamber 6 and the solution to be tested contained therein to a specific temperature, eliminating the influence of temperature on the acid-base concentration test results and improving the detection accuracy.

[0026] A bracket 4 is provided on the base 1 , and a clamping plate is provided on the top of the bracket 4 , and the clamping plate is used to support the probe 3 .

[0027] The first valve 12 and the second valve 14 are both three-way valves; the setting of the three-way valve allows the first valve 12 and the second valve 14 to both guide the airflow out of the detection box 5, ensuring that only the temperature control chamber 7 can be heated or cooled at the same time.

[0028] An exhaust port 15 is provided on one side of the top of the detection box 5 , and the exhaust port 15 is connected to the temperature control tube 8 .

[0030] Vortex tube 9 refrigeration is a method that uses the action of the vortex tube 9 to create a vortex in a high-speed airflow, separating it into cold and hot airflows. The cold airflow is then used to achieve refrigeration. The compressed and cooled gas enters the nozzle, where it expands and accelerates to the speed of sound. It then enters the vortex chamber tangentially, forming a free vortex. The angular velocity of the free vortex increases as it approaches the center. Due to the different angular velocities, friction is generated between the layers of the free vortex. The airflow in the center has the highest angular velocity. As a result, friction transfers energy to the outer layers of the airflow, which have lower angular velocities. The airflow in the center loses energy, resulting in lower kinetic energy, reduced velocity, and lower temperature. This airflow is then drawn out of one end through the orifice plate at the center of the vortex tube 9, producing the cold airflow needed for refrigeration. The airflow in the outer layers, on the other hand, gains momentum, increasing its kinetic energy. At the same time, friction with the turbine tube wall converts some of this kinetic energy into heat energy, which is then drawn out of the other end of the vortex tube 9, forming a hot airflow.

[0031] Working principle: First, inject the liquid to be tested into the holding chamber 6, select the detection temperature through the button on the display 2, and compare it with the temperature of the temperature sensor in the temperature control chamber 7 to determine whether heating or cooling is needed. Then the temperature control component works, compressed air enters the vortex tube 9, the cold air flow enters the cold pipe 11, and the hot air flow enters the heat pipe 13. When heating is required, the second valve 14 connects the heat pipe 13 and the temperature control tube 8, and the first valve 12 guides the cold air flow in the cold pipe 11 to discharge, heating the temperature control chamber 7 and the holding chamber 6. When cooling is required, the first valve 12 connects the cold pipe 11 and the temperature control tube 8, and the second valve 14 guides the hot air flow in the heat pipe 13 to discharge until the temperature sensor reads stabilize at the preset detection temperature. At this time, the compressed air injection stops, the temperature control component stops working, and then the end of the probe 3 is inserted into the liquid to be tested to perform acid-base concentration analysis, and the analysis results are displayed on the display screen.
