[0035] This disclosure provides a micro electrochemical workstation, with reference to Figures 1 to 5 As shown, the micro electrochemical workstation includes:

[0036] The workstation housing 1 contains a power supply component 2, a control component and a wireless transmission component 4, which are connected in communication with each other.

[0037] The adapter housing 5 is partially inserted into the first end of the workstation housing 1. The adapter housing 5 is provided with a three-electrode plug-in terminal 6. The three-electrode plug-in terminal 6 is electrically connected to the control component. The end of the three-electrode plug-in terminal 6 away from the workstation housing 1 is provided with a three-electrode interface 61.

[0039] The micro electrochemical workstation disclosed herein has a three-electrode interface 61 exposed at the end of the adapter housing 5 away from the workstation housing 1 via the first mounting interface 51. Users can select appropriate electrodes from the working electrode, reference electrode, and counter electrode for electrochemical testing according to experimental needs. The micro electrochemical workstation is equipped with a power supply component 2 and a wireless transmission component 4. The power supply component 2 is electrically connected to the control component, which can provide stable power support for the micro electrochemical workstation. The wireless transmission component 4 enables the workstation to have wireless transmission capabilities, facilitating remote monitoring and data sharing.

[0040] Specifically, please refer to the overall structure of the micro electrochemical workstation provided in this disclosure. Figure 1 As shown, Figure 2 This shows an exploded schematic diagram of one embodiment of a micro electrochemical workstation. Figure 3 A schematic diagram showing the matching of the workstation housing 1 and the adapter housing 5 in one embodiment of the micro electrochemical workstation is shown.

[0041] In one exemplary embodiment of this disclosure, reference is made to Figure 1 As shown, the workstation housing 1 includes an upper housing 11 and a lower housing 12, which are mated to form the workstation housing 1. (Reference) Figure 2 , Figure 3 As shown, the upper housing 11 and the lower housing 12 are matched by slots on three sides of the workstation housing 1 in the circumferential direction; so that after the upper housing 11 and the lower housing 12 are aligned, a second mounting interface 13 is formed at the first end. The second mounting interface 13 is used to match the adapter housing 5, and the adapter housing 5 is inserted into the second mounting interface 13 and connected to the adapter housing 5.

[0042] For example, the upper housing 11 and the lower housing 12 are detachably connected, which makes it convenient for users to replace the battery of the power supply component 2 or to perform maintenance.

[0043] For example, the workstation housing 1 has an overall cuboid structure with a length of approximately 60-65 mm, a width of 25-30 mm, and a height of 10-15 mm. For instance, in one embodiment, the length, width, and height of the workstation housing 1 are 62 mm, 27 mm, and 14 mm, respectively, and it has a compact design that is easy to carry and store.

[0044] For example, refer to Figure 2 , Figure 4 As shown, the control components include a PCB motherboard 3 and current and voltage control chips, charge pump boost integrated chips, operational amplifiers, surface-mount transistors, surface-mount capacitors, and surface-mount resistors electrically connected to the PCB motherboard 3. Other integrated circuit components may also be included. For example, the PCB motherboard 3 includes a main control module, which includes an LM9100 integrated chip for precise current and voltage control; it also includes an HX4002-MFC charge pump boost integrated chip, a TZ1333TR operational amplifier, and MMBT5401 (RANGE:200-300) surface-mount transistors, surface-mount capacitors (4.7uF±10% 16V), and surface-mount resistors (4.7kΩ±1% 100mW thick film resistors), ensuring the accuracy and stability of the workstation. In one exemplary embodiment, the micro electrochemical workstation of this disclosure is equipped with a variety of electrochemical testing functions, such as at least IT (chronoamperometry) testing, LSV (linear voltammetry) testing, CV (cyclic voltammetry) testing, DPV (differential pulse voltammetry) testing, SWV (square wave voltammetry) testing, RES (resistance testing), and OCP (open circuit voltage) testing.

[0045] The wireless transmission component 4 is electrically connected to the PCB motherboard 3. For example, the wireless transmission component 4 includes a Bluetooth integrated circuit, which can realize real-time data transmission through Bluetooth technology, facilitating remote monitoring and data sharing. Specifically, the Bluetooth integrated circuit can be a surface-mount / 2.4G / Bluetooth Low Energy (BLE) module.

[0046] For example, one end of the three-electrode plug-in terminal 6 is electrically connected to the PCB motherboard 3 via a pin, and the other end of the three-electrode plug-in terminal 6 is provided with a three-electrode interface 61. The adapter housing 5 is fixedly connected to the workstation housing 1. The three-electrode interface 61 is exposed in the adapter housing 5 through the first mounting interface 51, as shown in the reference. Figure 3 As shown.

[0047] In an exemplary embodiment of this disclosure, electrochemical detection can be performed by connecting a three-electrode system via the three-electrode interface 61, or the three-electrode interface 61 can be connected to a screen-printed electrode, thereby allowing the screen-printed electrode to be directly connected to the electrochemical workstation to complete different types of tests. Specifically, the control component can apply a voltage signal to the electrode system via the three-electrode interface 61, for example, applying a bias voltage to the counter electrode and the working electrode, applying a positive voltage to the counter electrode and a negative voltage to the working electrode, with the reference electrode serving as a stable voltage measurement feedback. The current of the working electrode is collected as a response electrical signal. The data can be transmitted to a mobile device APP via the Bluetooth function of the wireless transmission component 4, enabling experimental data to be transmitted to a remote device in real time, facilitating remote monitoring by experimental personnel. Exemplarily, the current detection accuracy of the micro electrochemical workstation of this disclosure is 10 pA.

[0048] For example, the inner sidewall of the lower housing 12 is provided with a plurality of positioning posts, and the PCB motherboard 3 is provided with a plurality of corresponding positioning holes. The positioning holes on the PCB motherboard 3 are matched one-to-one with the positioning posts of the lower housing 12, thereby fixing the PCB motherboard 3 in the lower housing 12 and preventing the PCB motherboard 3 from shaking or falling off the lower housing 12.

[0049] In one exemplary embodiment of this disclosure, reference is made to Figure 2 As shown, a first hole 14 is formed through the top surface of the upper housing 11. One end of a button 71 is installed in the first hole 14, and the other end of the button 71 is connected to a control component. The control component responds to the action of the button 71 to turn on or off the circuit that supplies power from the power supply component 2 to the control component. For example, the power switch on the PCB motherboard 3 responds to the action of the button 71 to turn on or off. For example, the power supply component 2 includes a lithium battery electrically connected to one side of the PCB motherboard 3, such as the side of the PCB motherboard 3 near the lower housing 12. The lithium battery can supply power to the electrical components of the workstation. The power supply component 2 may also include peripheral circuits such as a battery protection circuit. For example, the power supply component 2 includes a rechargeable lithium battery with a supply voltage of 3.7V, supporting fast charging to ensure long-term use.

[0050] For example, refer to Figure 2 , Figure 4 As shown, a charging interface 21 is electrically connected to the other side of the PCB motherboard 3. The charging interface 21 is used to connect to an external power source to charge the lithium battery. For example, the charging interface 21 is a Type-C interface. In addition to connecting to an external power source to charge the lithium battery, the charging interface 21 can also be connected to control components to save experimental data to an external storage device or transfer it to a computer for further analysis.

[0051] In one exemplary embodiment of this disclosure, reference is made to Figure 1As shown, the workstation housing 1 has a through third mounting interface 15 at its second end opposite to the first end. The third mounting interface 15 exposes at least the charging interface 21, allowing the workstation housing 1 to protect the charging interface 21 without affecting its function. For example, the third mounting interface 15 is located on the upper housing 11.

[0052] In one exemplary embodiment of this disclosure, reference is made to Figure 2 as well as Figure 5 As shown, a button protective sleeve 72 is provided between the upper housing 11 and the button 71. Figure 5 A schematic diagram of the assembly of button cover 72 and button 71 is shown. At least a portion of button cover 72 is in contact with the inner wall of the first hole 14. Button cover 72 has a button mounting portion 721. One end of button 71 is mounted in button mounting portion 721, and the other end of button 71 protrudes outside button cover 72 and is connected to power supply component 2.

[0053] In one exemplary embodiment of this disclosure, the button protective cover 72 is made of silicone. The button protective cover 72 can protect and fix the button 71, and can improve the feel of pressing the button 71.
