Description

Technical Field

[0001] This utility model relates to the field of water treatment and disinfection technology, and in particular to a titanium electrode electrolytic ozone water disinfection device based on conductive electrode descaling technology. Background Technology

[0002] Current electrolytic ozone water sterilizers typically use titanium anodes coated with precious metals (such as iridium and ruthenium oxide) and stainless steel cathodes. Their main drawbacks include: Scaling: Calcium and magnesium ions in the water form stubborn scale (CaCO3, Mg(OH)2) on the cathode surface during electrolysis. The damage caused by scaling includes: Efficiency degradation: Scale covers the electrode's active coating, increasing resistance and leading to a sharp drop in ozone production efficiency and increased energy consumption. Shortened lifespan: Scale causes localized overheating, damaging the valuable titanium coating, permanently damaging the electrodes, and significantly shortening the equipment's lifespan. Difficult maintenance: Frequent cleaning with acidic cleaning agents is required, which is inconvenient and poses safety hazards.

[0003] Existing descaling technologies (such as mechanical scraping and ultrasonic descaling) are complex and costly to use in small household appliances. Therefore, there is an urgent need for a household ozone water disinfection technology that can automatically, online, and non-destructively remove limescale. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 and Figure 2The illustrated titanium electrode electrolytic ozone water sterilizer based on conductive electrode descaling technology includes an electrolytic cell housing 1, a display and control panel 4 on the front of the housing, a water flow channel and a constant current power supply 7 inside the housing, an inlet 2 and an outlet 3 at both ends of the water flow channel, a pre-filtration module 5 and a sterilization module 6 within the water flow channel, the sterilization module including a titanium-coated anode 10 and a titanium cathode 11, with a conductive electrode 12 positioned between the titanium-coated anode and the titanium cathode, and a circuit control system that controls the positive and negative polarity changes of the titanium-coated anode, titanium cathode, and conductive electrode. In this embodiment, the sterilization module adds a third electrode—a conductive electrode—to the original structure, made of titanium, which can be controlled by the circuit control system to change its positive and negative polarity.

[0021] Specifically, such as Figure 3 and Figure 4 As shown, the titanium-coated anode, titanium cathode, and conductive stage all include conductive rods 8. Multiple conductive laminates 9 are connected to the conductive rods 8, each made of titanium substrate. The conductive rods 8 are connected to a power source via wires. Through holes are provided on each titanium substrate, and the conductive rods pass through these holes and are then positioned and fixed using fasteners. To facilitate the regular arrangement of the conductive laminates, gaps are created at different positions on adjacent laminates, allowing for neat arrangement and connection.

[0022] Specifically, the circuit control system includes a power switching module and a control unit; the control unit is used to control the power switching module to switch the positive and negative terminals of the DC power supply, thereby switching between ozone generation mode and descaling mode. The circuit control system primarily achieves the switching between two main operating modes.

[0023] Specifically, the power switching module is an H-bridge circuit or a relay group, and the control unit is an MCU microcontroller.

[0024] Specifically, the pre-filtration module includes a 304 stainless steel filter element. This filter element performs primary filtration of the water.

[0025] Specifically, a water flow sensor is installed on the water flow channel. The water flow sensor detects the flow rate of the treated water and displays it on the panel in real time, making it easy to check the working status at any time.

[0026] The working process of this utility model is as follows:

[0027] Normal operating mode (ozone generation mode): The control unit controls the power switching module to connect the DC positive terminal to the titanium-coated anode and the DC negative terminal to the titanium cathode. At this time, the titanium-coated anode undergoes an oxidation reaction to produce ozone (O3) and oxygen (O2), while the titanium cathode undergoes a reduction reaction to produce hydrogen (H2) and attract calcium and magnesium ions, thus initiating scaling.

[0028] Descaling Mode: The control unit automatically activates the descaling mode according to a preset cycle (e.g., every 30 minutes) or based on an algorithm (e.g., judging the degree of scaling based on current / voltage changes). In this mode, the control unit controls the power switching module to switch the DC positive terminal to the conductor and the DC negative terminal to the titanium cathode. At this time, the circuit loop becomes: conductor (new anode) -> electrolyte -> titanium cathode (new cathode). Under the action of a strong electric field, the scale (mainly CaCO3, Mg(OH)2) adhering to the surface of the titanium cathode will undergo an electrolytic reaction or an acid dissolution reaction: Electrolysis: The hydrogen gas generated at the cathode makes the local area alkaline, while oxygen and protons (H+) are generated on the conductor, which is the new anode. + These H + It will quickly diffuse to the cathode surface, neutralize in the alkaline environment, and directly dissolve the scale: CaCO3 + 2H2O + ->Ca 2+ +CO2↑+H2O;Mg(OH)2+2H + ->Mg 2+ +2H2O.

[0029] Physical stripping: The tiny hydrogen bubbles generated at the cathode also have a physical flushing and stripping effect on the scale layer. After a brief descaling operation (e.g., 10-300 seconds), the system automatically switches back to normal operating mode and continues to produce high-concentration ozone water.

[0030] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
