TECHNICAL FIELD

[0024] Please refer to Figs. 1-3 In this embodiment, a water quality ion concentration detection device, including host computer 1, probe 2, connecting line 3 of host computer 1 and probe 2;Wherein, the probe 2 includes shell 21, electrode assembly 22 arranged in shell 21;Shell 21 is provided with hole site 4 for accommodating the sensing end 221 of electrode assembly 22.The host computer 1 is responsible for data transmission and processing, and the water sample to be detected is titrated to the surface of the probe 2, the electrode assembly 22 and the ion in the water sample are inducted to form a channel, a potential difference is generated, the potential signal is transmitted to the host computer 1 by the connecting line 3, and the potential signal is converted into concentration data and displayed.

[0025] Further, the electrode assembly 22 includes magnesium ion electrode 222, calcium ion electrode 223 and reference electrode 224.Magnesium ion electrode 222 is mainly used for measuring the concentration of magnesium ions in water sample, and the concentration of magnesium ions is responded by potential change, so as to realize quantitative detection of magnesium ion concentration;Calcium ion electrode 223 is used for measuring the concentration of calcium ions in solution, and the potential signal related to the concentration of calcium ions is generated by electrochemical reaction with calcium ions, so as to realize accurate measurement of the concentration of calcium ions;The reference electrode 224 and the working electrode (magnesium ion electrode 222, calcium ion electrode 223) jointly constitute an electrochemical circuit, so that the current can flow in the circuit, thereby realizing detection and conversion of electrochemical signal.

[0026] Further, the shell 21 is also provided with temperature sensor 23.Temperature sensor 23 is used for detecting the temperature of water sample, and the temperature signal is also transmitted to host computer 1 for processing and converted into temperature display.

[0027] Further, the sensing end 221 is lower than the end face height of the shell 21.The sinking design of the electrode sensing end avoids the contact between the electrode and the outside when not in use, prevents the electrode material from being worn and falling off due to frequent friction or improper storage.

[0028] In other embodiments, the end face of the shell 21 provided with hole site 4 is inwardly recessed, further protecting the electrode from wear and tear and prolonging the service life of the electrode.

[0029] Further, the sensing end 221 of each electrode is covered with an ion protection film 2211. The ion protection film 2211 provides physical protection for the electrode, reduces direct contact between the sensing end of the electrode and the external environment, and reduces electrode material wear and shedding caused by mechanical factors such as friction and collision. In addition, the ion protection film can selectively allow certain ions to pass through while blocking other interfering ions, thereby improving the detection selectivity and sensitivity of the electrode to target ions (such as calcium and magnesium ions).

[0030] Further, the shell 21 includes an upper shell 211 and a lower shell 212 that are sealed together. The connecting line 3 is made of a soft material, and the connection end of the connecting line 3 is sealed by a silicone wire plug 5, thereby avoiding the influence of repeated plugging and unplugging on the sealing performance.

The purpose is to convert the potential signal and the temperature signal into a numerical value and a temperature, which are displayed on the display 12.

[0032] In use, the water sample to be detected is titrated onto the surface of the probe. The water sample is communicated to the electrode and the temperature sensor through the micro-flow channel between the upper shell and the sensing end. The electrode and the magnesium ions and calcium ions in the water sample form a channel, generating a potential difference. The wire harness transmits the potential signal and the temperature signal to the data processing and transmission module. The scale data and the temperature data established by the built-in chip convert the electrical signal into the concentration of calcium and magnesium ions in the solution, and display the specific numerical value and temperature on the display. The built-in wireless transmission device can transmit the water sample data to the cloud platform in real time.
