Description

Technical Field

[0001] This invention belongs to the field of electrode cleaning technology and provides an integrated device for cleaning and drying electrodes of a general surface charge measuring instrument. Background Technology

[0002] Surface charge is the charge distribution characteristic formed at the interface when a material comes into contact with a liquid, and it is one of the important parameters characterizing the interfacial properties of materials. When a solid comes into contact with a liquid, due to reasons such as "ion adsorption," "molecular ionization," or "lattice defects," the solid surface becomes charged, while the surrounding liquid contains an equal amount of counterions with opposite signs, forming the so-called "electric double layer" (EDL). This surface charge phenomenon is ubiquitous in nature and industrial applications, playing a crucial role in fields ranging from micro- and nano-fluidic systems and biomedical detection to the development of energy materials. Surface charge density and its related potential parameters (such as zeta potential and surface potential) directly affect processes such as "interfacial chemical reactions," "molecular adsorption behavior," "colloidal stability," and "electromechanical phenomena" (such as electroosmosis and electrophoresis).

[0003] The research and development of surface charge measurement technology is of great significance for a deeper understanding of interfacial phenomena, optimization of material properties, and design of novel functional systems. For example, in microfluidic chips, surface charge determines fluid flow characteristics and molecular transport efficiency; in the field of biosensors, surface charge affects protein adsorption and cell behavior; and in energy materials, surface charge regulates interfacial energy conversion efficiency and charge storage mechanisms. With the rapid development of nanotechnology and biotechnology, higher demands are being placed on the accuracy, spatial resolution, and applicable environment of surface charge measurement technology, driving the emergence and development of various innovative measurement methods.

[0004] The sample testing process of the surface charge analyzer (USCA-2001) developed by the applicant is briefly as follows: The sample is placed in the sample tray of the instrument, the computer software system sets the relevant parameters, the instrument starts automatic testing, and after the test, the instrument automatically calculates the test results and records and saves the data. The instrument operation during the testing process is briefly as follows: First, all moving parts of the instrument are reset and ready according to the method transmitted by the software. The computer host sends instructions, and the two electrodes are ready to begin calibration. The software records each calibration result and converts the signal value into a standard curve, which is then stored for subsequent calculations. After calibration, the instrument automatically tests the sample; the entire process requires no manual operation. During instrument operation, the electrodes are first cleaned with pure water (ensuring thorough cleaning). After cleaning, the electrodes need to be dried (no water droplets are allowed, but the bulb should remain moist). Once the electrodes are dry, the next step can be performed. The electrodes need to be cleaned after each test.

[0005] However, traditional methods involve manually stirring the electrodes in a cup of pure water, changing the water after each stirring, and then gently absorbing the water with lint-free absorbent paper or vigorously shaking them dry. This traditional washing method wastes a lot of water and cannot guarantee that the washing water is not contaminated. Traditional drying methods, where absorbent paper directly contacts the electrode bulb, can easily introduce foreign matter, and absorbing or wiping the electrode can scratch it. Foreign matter on the electrode bulb can cause measurement errors, and scratches render the electrode unusable. Vigorous shaking is cumbersome; the electrode must not collide with surrounding objects during the process, and it cannot guarantee uniform drying. Furthermore, it cannot ensure close contact between the positive and negative electrodes, as the process may cause the electrode to be inverted, creating air bubbles. Inadequate contact between the positive and negative electrodes and the presence of air bubbles in the electrode solution both affect the measurement results.

[0006] Therefore, the traditional electrode cleaning method needs to be improved to meet the requirements of less manual labor, automation, and integrated cleaning and drying. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated electrode cleaning and drying device for a general-purpose surface charge measuring instrument that is efficient, automated, and low-risk. It mainly solves the problems of low efficiency and potential damage to electrodes caused by traditional electrode cleaning, so as to improve the efficiency of cleaning and drying by reducing manual operation, while ensuring the integrity of the electrode and the accuracy of measurement, thereby extending the service life of the electrode and ensuring its normal use.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] This utility model discloses an integrated electrode cleaning and drying device for a general surface charge measuring instrument, comprising a cleaning cup for cleaning and drying electrodes. The cleaning cup consists of a top sleeve and a washing tank. The top sleeve is connected to a water inlet connector and an air inlet connector. The top sleeve is fitted onto the upper end of the washing tank, and a drain connector is connected to its bottom end. The top sleeve has a water inlet channel, a water inlet annular groove, an air inlet channel, and an air inlet annular groove. The water inlet annular groove and air inlet annular groove are arranged radially around the top sleeve at intervals along the axial direction. The water inlet channel connects the water inlet connector and the water inlet annular groove. The air inlet channel connects the air inlet connector and the air inlet annular groove. The washing tank has a water outlet channel, an air outlet channel, an open cavity chamber, and a drain channel. The open cavity chamber is used to accommodate the entry and exit of electrodes. Multiple water outlet channels and air outlet channels are arranged radially around the washing tank at intervals along the axial direction. The water outlet channels connect the water inlet annular groove and the open cavity chamber. The air outlet channels connect the air inlet annular groove and the open cavity chamber. The drain channel connects the open cavity chamber and the drain connector. By adopting the above scheme, this integrated electrode cleaning and drying device can meet the stringent requirements of the general surface charge measuring instrument for electrode cleaning and drying.

[0010] Optionally, up to two water inlet ring grooves and at least two air inlet ring grooves are provided, with the water inlet ring grooves and air inlet ring grooves arranged alternately, and one air inlet ring groove located on the upper part of the top sleeve. This design can avoid interference between two directly adjacent grooves, ensuring smoother flow of water and gas during the cleaning process; and through this structure and arrangement, the cleaning device can achieve a more efficient cleaning effect, improving the performance and reliability of the equipment.

[0011] Optionally, the water outlet and air outlet are angled downwards. This angled design enhances the flow of the cleaning cup, improving cleaning and ventilation efficiency and making it more effective and reliable.

[0012] Optionally, the water outlet and air outlet channels can be configured with tapered orifices that gradually taper from the outside in. This tapered orifice design not only improves fluid flow performance but also enhances the overall efficiency and reliability of the cleaning cup.

[0013] Optionally, the bottom of the open chamber of the washing tank is provided with a transition arc section and an inverted frustum section, with the inverted frustum section connecting to the drainage channel. In this way, due to the design of the transition arc section and the inverted frustum section, the washing tank can improve the fluidity and drainage efficiency of the waste liquid during the cleaning process, providing better performance and reliability for the cleaning process.

[0014] Optionally, the cleaning cup also includes an outer shell mounted on the top sleeve and used to fit over the top sleeve and the sink. The top of the outer shell has a recessed platform, and the top of the top sleeve has a protrusion that matches the recessed platform. This allows for a tight fit between the two, enhancing overall stability. This design not only increases the structural stability of the cleaning cup and improves its aesthetics and user experience, but also facilitates later maintenance and cleaning. Users can easily disassemble the outer shell to clean the internal structure.

[0015] Optionally, a pure water tank and an air compressor are also included. The air compressor is connected to an air inlet connector via an air inlet pipe, and also connected to the pure water tank via a blowing pipe. The pure water tank is connected to a water inlet connector via a water inlet pipe. Using this solution, firstly, the cleaning process uses the air compressor to deliver pure water from the pure water tank to the cleaning cup, which is then sprayed out sequentially through the water inlet connector, water inlet channel, water inlet ring groove, and water outlet, forming a continuous and stable water flow to rinse the electrodes. This process ensures that the electrodes are quickly cleaned while minimizing secondary contamination of the water source. Secondly, after rinsing, the drying process uses the air compressor to deliver compressed air or room temperature air to the cleaning cup, which is then sprayed out sequentially through the air inlet connector, air inlet channel, air inlet ring groove, and air outlet, forming a continuous and stable dry air flow to thoroughly dry the electrodes. This process effectively reduces contact between the electrodes and other media, thereby reducing the risk of tipping during the drying process and ensuring the stability of the internal liquid. In addition, using room temperature air to dry the electrode can avoid drastic temperature changes, thereby preventing changes in electrode performance and ensuring the accuracy of the measurement results.

[0016] Optionally, a first pressure gauge and a first valve are installed on the air inlet pipe; a second pressure gauge and a second valve are installed on the air blowing pipe. The first pressure gauge on the air inlet pipe monitors the air pressure in real time, ensuring appropriate air pressure data is obtained before the drying operation. The first valve, such as a solenoid valve, controls the amount of air flowing in and the pressure reaching the inlet. Users can set the pressure as needed, flexibly adjusting the air flow and pressure to achieve optimal drying results. The second pressure gauge on the air blowing pipe monitors the pressure of the pure water. This helps ensure that the water pressure is appropriate during rinsing to effectively wash away contaminants adhering to the electrode bulbs. The second valve can adjust the water flow and pressure, ensuring that the water flow force applied during rinsing can be adjusted as needed, thus achieving flexibility under different cleaning requirements.

[0017] Compared with the prior art, the present invention has one or more of the following advantages:

[0018] 1) High-efficiency cleaning: This integrated electrode cleaning and drying device can achieve automated control of components such as compressors and valves through a PLC controller, and realize the automated design of cleaning cup in water spray rinsing and air drying. This enables the electrode cleaning and drying process to be completed quickly, greatly improving work efficiency and reducing the risks of manual operation and damage to the electrodes.

[0019] 2) Reduced risk of contamination and improved temperature stability: This integrated electrode cleaning and drying device can provide a continuous and stable flow of clean water and air at a certain pressure. This not only effectively prevents water contamination during the cleaning process, but also avoids the negative impact of temperature changes on electrode performance by drying with room temperature air, thus improving the accuracy and repeatability of measurements.

[0020] In summary, this integrated electrode cleaning and drying device provides an efficient, automated, and low-risk solution to meet the electrode cleaning and drying requirements of general surface charge measuring instruments.

[0021] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0031] like Figure 1As shown, this integrated electrode cleaning and drying device for a general-purpose surface charge measuring instrument mainly includes a cleaning cup 1, a pure water tank 2, and an air compressor 3. The cleaning cup 1 is used to clean and dry the electrode 11. Its internal structure consists of a top sleeve 102 and a washing tank 105. The top sleeve 102 is threadedly connected to a water inlet connector 103 and an air inlet connector 104 for connecting pure water for cleaning and air for drying, respectively. The top sleeve 102 is fitted onto the upper end of the washing tank 105 with a sealed interference fit, and a drain connector 1 is threadedly connected to its bottom end. 06 is used to discharge the waste liquid formed after rinsing with pure water; the air compressor 3 is connected to the air inlet connector 104 through the air inlet pipe 4 to deliver compressed air or room temperature air to the cleaning cup 1, thereby achieving the purpose of air purging and drying the electrode; the air compressor 3 is also connected to the pure water tank 2 through the air blowing pipe 7, and the pure water tank 2 stores pure water for cleaning, and is connected to the water inlet connector 103 through the water inlet pipe 10, so that the pure water in the pure water tank 2 is squeezed out and delivered to the cleaning cup 1 by the air pressure provided by the air compressor 3, thereby achieving the purpose of rinsing and cleaning the electrode. Using the above scheme, this integrated electrode cleaning and drying device first uses pure water to rinse the electrode, which can ensure that the electrode is quickly cleaned and the flowing water can ensure that the water source is not contaminated; then it uses air blowing to dry the electrode, that is, using compressed air or room temperature air provided by the air compressor to dry the electrode ball in all directions, and room temperature air drying can reduce the contact between the electrode and other media, prevent the electrode from being inverted and ensure the stability of the electrode liquid, and prevent the ambient temperature around the electrode from changing drastically (drastic temperature changes will change the electrode performance and affect the measurement results). In addition, conventional automation controllers, such as PLC-controlled programmable controllers, can be added to automate the control of components such as air compressors and valves, thereby reducing manual intervention and improving cleaning efficiency. In this way, this integrated electrode cleaning and drying device can not only achieve efficient cleaning but also rapid drying after cleaning.

[0032] Specifically, such as Figure 2-6As shown, the cleaning cup 1 has a water inlet channel 1021, a water inlet annular groove 1022, an air inlet channel 1023, and an air inlet annular groove 1024 inside the top sleeve 102. The water inlet annular groove 1022 and the air inlet annular groove 1024 are arranged radially at intervals along the axial direction of the top sleeve 102. The water inlet channel 1021 is responsible for introducing water flow and connects the water inlet connector 103 and the water inlet annular groove 1022 to ensure smooth water flow. The air inlet channel 1023 is used to introduce gas and connects the air inlet connector 104 and the air inlet annular groove 1024 to allow gas to enter smoothly. The washing tank 105 has a water outlet channel 1051, an air outlet channel 1052, an open chamber 1053, and a drainage channel 1056. The open chamber 1053 is used to accommodate the entry and exit of the electrode 11. Multiple water outlet channels 1051 and air outlet channels 1052 are arranged radially at intervals along the axial direction of the washing tank 105. For example, in this example, the water outlet channels 1051 and air outlet channels 1052 corresponding to the single-layer water inlet ring groove 1022 or air inlet ring groove 1024 are set to 6-12. The water outlet channel 1051 is used to connect the water inlet ring groove 1022 and the open chamber 1053, and is responsible for introducing water into the open chamber 1053. The air outlet channel 1052 is used to connect the air inlet ring groove 1024 and the open chamber 1053, and is responsible for introducing gas into the open chamber 1053. The drainage channel 1056 is used to connect the open chamber 1053 and the drainage connector 106, and is responsible for discharging the waste liquid after cleaning. In the design of the washing tank 105 and the top sleeve 102, the channels and annular grooves are arranged at intervals along the axial direction and distributed in a radial ring. This design can effectively ensure the efficient flow of water and gas and reduce cross interference.

[0033] In this embodiment, at most two water inlet annular grooves 1022 are provided, such as one water inlet annular groove 1022 located in the second layer in this example. At least two air inlet annular grooves 1024 are provided, such as three air inlet annular grooves located in the first, third, and fourth layers in this example. This design improves the inflow efficiency of water and gas, ensuring full utilization of gas during the cleaning process. Furthermore, the water inlet annular grooves 1022 and air inlet annular grooves 1024 are arranged alternately to ensure uniform distribution of liquid and gas, reduce mutual interference, and an air inlet annular groove 1024 is located on the upper part of the top sleeve 102. This ensures that gas is always present in the open chamber of the washing tank after the electrode is retracted, allowing for effective air blowing and drying, thus ensuring the cleaning effect.

[0034] In this embodiment, the water outlet channel 1051 and the air outlet channel 1052 are inclined downwards. This inclined design of the water outlet and air outlet channels helps reduce fluid flow resistance, increases flow velocity, and enhances the cleaning effect on the electrodes. It also reduces water and gas retention, preventing water and gas from accumulating inside the channels, thereby improving overall efficiency.

[0035] In this embodiment, the water outlet channel 1051 and the air outlet channel 1052 are configured as tapered orifices that gradually decrease in size from the outside to the inside. This tapered orifice design allows the fluid to flow at a faster velocity as the orifice diameter gradually decreases. This characteristic helps to enhance the flow efficiency of both water and gas.

[0036] In this embodiment, the bottom of the open chamber 1053 of the washing tank 105 is sequentially provided with a transition arc section 1054 and an inverted frustum section 1055, with the inverted frustum section 1055 connecting to the drainage channel 1056. The transition arc section 1054 is located at the initial position at the bottom of the open chamber 1053, and its main function is to connect different parts, ensuring a smooth transition of water flow. It helps to mitigate abrupt changes in water flow, reducing potential turbulence and impact, thereby providing a more stable flow environment. The inverted frustum section 1055 is a downwardly tapering structure, designed to further guide the water flow towards the drainage channel 1056; simultaneously, the inverted frustum section 1055 is directly connected to the drainage channel 1056. This structural design ensures that the waste liquid after rinsing in the washing tank can be smoothly discharged, improving drainage efficiency and preventing water accumulation. Thus, by setting the transition arc section and the inverted frustum section, the water flow path in the washing tank is optimized, reducing flow obstruction and thereby enhancing the cleaning effect. It also improves drainage efficiency. The design of the inverted truncated cone section further enhances the effect of gravity, allowing the water in the washing tank to be discharged more quickly and effectively, maintaining a smooth washing process.

[0037] In this embodiment, the cleaning cup 1 also includes a housing 101 disposed on the top sleeve 102 and used to fit over the top sleeve 102 and the washing tank 105. The top of the housing 101 has a recess 1011, and the top of the top sleeve 102 has a protrusion 1025 that matches the recess 1011, thus achieving a stable connection and fixation. The housing 101 not only protects the built-in top sleeve 102 and washing tank 105 but also has a decorative effect, providing an aesthetically pleasing design. The connection method uses screws to fix the entire structure together, which enhances the strength of the connection and ensures that it will not loosen or detach during use.

[0038] In this embodiment, a first pressure gauge 5 and a first valve 6 are installed on the air inlet pipe 4; a second pressure gauge 8 and a second valve 9 are installed on the air blowing pipe 7. Thus, during pure water rinsing, the pure water with a certain pressure (adjustable) is supplied via the second pressure gauge 8 and the second valve 9, ensuring that contaminants adhering to the electrode bulb are more easily washed away; this pressure control helps improve the rinsing effect and cleaning efficiency. During air drying, the air with a certain pressure (adjustable) is supplied via the first pressure gauge 5 and the first valve 6, blowing away large water droplets on the electrode surface and ensuring that the water adhering to them vaporizes quickly. Furthermore, by controlling the drying time and air pressure, the hydration film on the electrode surface can be preserved to a certain extent, preventing surface damage caused by complete drying. Therefore, by effectively controlling the fluid pressure and flow rate during rinsing and drying, the overall performance and applicability of the cleaning equipment are improved, ensuring optimized and flexible control of the cleaning and drying processes.

[0039] The core technology of this utility model lies in providing an integrated electrode cleaning and drying device that combines cleaning and drying functions, has a high degree of automation, effectively protects electrodes, and improves measurement accuracy and efficiency, in order to meet the electrode cleaning and drying requirements of general surface charge measuring instruments. Specifically, it is embodied in:

[0040] 1) Integrated cleaning and drying structure design. Pure water rinsing and air drying are achieved through a single cleaning cup, resulting in a compact structure and continuous operation; furthermore, the design of the top sleeve and washing tank allows for independent control and efficient guidance of multi-channel fluids (water and air).

[0041] 2) Optimized arrangement of annular grooves and channels. The water inlet annular grooves and air inlet annular grooves are arranged alternately to avoid fluid interference; and the water outlet / air outlet channels are inclined downward and have a conical design to enhance fluid dynamics and cleaning effect.

[0042] 3) Optimized bottom structure for drainage and anti-accumulation. The bottom of the open chamber of the washing tank adopts a transition arc section + inverted truncated cone section design, which can effectively guide the smooth discharge of waste liquid and avoid water accumulation.

[0043] 4) External system integration and pressure control. By using an air compressor, pure water tank, pressure gauge and valves, the pressure of the cleaning and drying process can be adjusted and the process can be controlled; and the use of pure water for continuous and stable one-time clean rinsing with a certain pressure can ensure that the electrodes are clean; and the use of room temperature air to dry can not only quickly dry the electrode surface, but also avoid the impact of temperature changes on electrode performance.

[0044] 5) Automation and replacement of manual labor: The cleaning and drying process can be fully automated through PLC and other controllers, reducing manual intervention and lowering operational risks and electrode damage.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
