AI Technical Summary

Technical Problem

In existing electrolytic cell designs, the electrode layout of the three-electrode system leads to a crowded operating space, and the working electrode and reference electrode are prone to collision with the counter electrode during adjustment, affecting measurement accuracy and safety.

Method used

The counter electrode is placed at the bottom of the electrolytic cell body. The elastic electrolytic cell is floatingly connected to the support base by a buffer spring. Combined with the lifting drive mechanism and liquid suction component, the electrode collision is avoided and the space utilization is optimized.

Benefits of technology

It eliminates the risk of collision between electrodes, optimizes the use of space above the electrolytic cell, and improves the ease of operation, accuracy, and safety of measurement.

Abstract

The application provides a three-electrode measuring system and relates to the field of electrochemical measuring instruments. The three-electrode measuring system comprises: an electrode holder, which is provided with a reference electrode and a rotating electrode; an elastic electrolytic cell, which is arranged below the electrode holder and comprises an electrolytic cell body, a counter electrode arranged at the bottom of the electrolytic cell body, and a conductive part penetrating through the cell wall and electrically connected with the counter electrode; a lifting driving mechanism, which comprises a linear driving module, a bearing seat and a buffer spring, the cell body of the elastic electrolytic cell is floatingly connected to the bearing seat through the buffer spring, and the linear driving module is connected with the bearing seat; and a liquid suction assembly. In the scheme, the counter electrode is built-in at the bottom of the electrolytic cell body, thereby avoiding the problem that the counter electrode occupies the space above, when the working electrode or the reference electrode is in contact during adjustment of the immersion depth, the floating characteristics of the buffer spring allow the electrolytic cell body to produce a certain displacement to buffer the impact.
