[0001] This utility model relates to the field of medical device disinfection technology, specifically a two-stage electrolysis and photocatalytic sterile water circulation device. Background Technology

[0002] In settings such as dental treatment units and dental clinics, automated disinfection of dental chairs is required. When performing disinfection, the dual-stage electrolysis and photocatalytic sterile water circulation equipment needs to circulate the electrolysis water (electrolyte).

[0003] A photocatalytic sterilization and disinfection device with application publication number CN117414456A includes a disinfection box. An activated carbon layer is slidably installed inside the disinfection box. A titanium dioxide photocatalyst plate is slidably installed below the activated carbon layer inside the disinfection box. An ultraviolet lamp is fixedly installed between the activated carbon layer and the titanium dioxide photocatalyst plate inside the disinfection box. An ozone generator and a plasma generator are fixedly installed at both ends on the lower surface of the disinfection box, respectively. A fan is fixedly installed between the ozone generator and the plasma generator inside the disinfection box. However, the above document still has shortcomings. During use, the motor, driven by the cooperation of a first driving mechanism and a cleaning mechanism, drives the cleaning mechanism... The belt rotates, causing the first drive shaft to rotate, which in turn causes the first drive shaft to rotate the first bevel gear. Then, through the interaction of the first and second bevel gears, the first bevel gear rotates the second bevel gear, which in turn causes the second bevel gear to rotate the second drive shaft. This causes the second drive shaft to carry the cleaning plate to clean the filter. At the same time, through the interaction of the rotating shaft and the motor, the motor rotates the rotating shaft, which in turn causes the rotating shaft to rotate the drive disc, which in turn causes the drive disc to rotate the drive block. The drive block causes the knocking rod to slide up and down reciprocally within the guide rod. When the above-mentioned photocatalytic sterilization and disinfection equipment is used for automated disinfection of dental chairs, there are problems such as low disinfection efficiency, complicated operation, and easy contamination of the water system.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The electrolysis cell is fixedly installed inside the primary disinfection tank. The primary disinfection tank is fixedly connected to the outer wall of one end of the inlet pipe. The outer wall of the inlet pipe is equipped with a tap water inlet manual valve, an inlet pressure sensor, an inlet solenoid valve, and an inlet filter. The primary disinfection tank is fixedly connected to the outer wall of one end of the second discharge pipe.

[0007] Preferably, a primary water tank level controller is fixedly installed inside the primary disinfection tank, and the primary disinfection tank is fixedly connected to the outer wall of one end of the first pipeline.

[0012] Preferably, the secondary disinfection tank is connected to the primary disinfection tank via a fourth pipe.

[0013] Preferably, the secondary disinfection tank is fixedly connected to the outer wall of one end of the first discharge pipe.

[0014] The dual-stage electrolysis and photocatalytic sterile water circulation device proposed in this utility model has the following advantages: Water from the primary disinfection tank enters the secondary disinfection tank through a fourth pipe. The titanium dioxide photocatalytic layer and ultraviolet lamp inside the secondary disinfection tank further disinfect the tap water, achieving photocatalytic sterilization. The secondary tank level controller keeps the tap water level within a certain range.

[0022] See attached document Figure 1-5 In this embodiment, the two-stage electrolysis and photocatalytic sterile water circulation equipment includes a primary disinfection tank 1 and an electrolytic cell 2. The electrolytic cell 2 is fixedly installed inside the primary disinfection tank 1. The electrolytic cell 2 contains titanium-plated ruthenium-iridium anode rods and titanium cathode rods. Electrolysis using the titanium-plated ruthenium-iridium anode rods and titanium cathode rods achieves sterilization of the dental chair. The electrolytic cell uses titanium-plated ruthenium-iridium anodes and titanium cathode rods, with a current density of 10-20 mA / cm². 2The process involves electrolysis to generate hypochlorous acid (effective chlorine concentration 20-60 mg / L) for 1-3 minutes, killing 99.9% of bacteria and viruses. The primary disinfection tank 1 is fixedly connected to the outer wall of one end of the inlet pipe 3. Water is injected into the primary disinfection tank 1 through the inlet pipe 3. The outer wall of the inlet pipe 3 is equipped with a manual water inlet valve 4, an inlet pressure sensor 5, an inlet solenoid valve 6, and an inlet filter 7. The manual water inlet valve 4 controls the opening and closing of the inlet pipe 3. The inlet pressure sensor 5 detects the water pressure inside the inlet pipe 3. The inlet filter 7 is a 0.5-micron filter that removes impurities from the tap water. The primary disinfection tank 1 is fixedly connected to the outer wall of one end of the second discharge pipe 21, which facilitates the discharge of water from the primary disinfection tank 1. The water is discharged, and a control valve is installed on the outer wall of the second discharge pipe 21 to control its opening and closing. A primary water tank level controller 8 is fixedly installed inside the primary disinfection water tank 1. The primary water tank level controller 8 controls the liquid level inside the primary disinfection water tank 1 within a certain range. The primary disinfection water tank 1 is fixedly connected to the outer wall of one end of the first pipe 9. The primary disinfection water tank 1 is connected to the first pipe 9. The other end of the first pipe 9 is fixedly connected to the dental chair 10 through a flange. The first pipe 9 is connected to the dental chair 10. The dental chair 10 includes a dental chair inside. The right side of the dental chair 10 is fixedly connected to the second pipe 11 through a flange. The dental chair 10 is connected to the second pipe 11.

[0023] A pipe pressure sensor 12 is installed on the outer wall of the second pipe 11. The pipe pressure sensor 12 detects the water pressure inside the second pipe 11. The end of the second pipe 11 is fixedly connected to the circulating water pump 13, and the second pipe 11 is connected to the circulating water pump 13. A third pipe 14 is fixedly connected to the output end of the circulating water pump 13, and the circulating water pump 13 is connected to the third pipe 14. The outer wall of the end of the third pipe 14 is fixedly connected to the secondary disinfection tank 15, and the third pipe 14 is connected to the secondary disinfection tank 15. A secondary water tank level controller is fixedly installed inside the secondary disinfection tank 15. 16. Titanium dioxide photocatalyst layer 17 and ultraviolet lamp 18, secondary water tank level controller 16 controls the liquid level inside the secondary disinfection tank 15 within a certain range. The secondary disinfection tank 15 is connected to the primary disinfection tank 1 through the fourth pipe 19. Water inside the primary disinfection tank 1 enters the interior of the secondary disinfection tank 15 through the fourth pipe 19. The secondary disinfection tank 15 is fixedly connected to the outer wall of one end of the first discharge pipe 20. The water inside the secondary disinfection tank 15 can be discharged through the first discharge pipe 20. The outer wall of the first discharge pipe 20 is provided with a control valve to control its opening and closing.

[0024] Water from the primary disinfection tank 2 enters the secondary disinfection tank 15 through the fourth pipe 19. The titanium dioxide photocatalyst layer 17 and ultraviolet lamp 18 inside the secondary disinfection tank 16 further disinfect the tap water, achieving photocatalytic sterility. The secondary tank level controller 16 controls the tap water level in the secondary disinfection tank 15 within a certain range. The circulating water pump 13 is started, and the circulating water pump 13 draws water from the secondary disinfection tank 15 through the third pipe 14 and draws it into the dental chair 10 through the second pipe 11. The sterile water from the dual-stage electrolysis and photocatalysis enters the dental chair 10 to automatically disinfect the dental chair. After the water has been automatically disinfected inside the dental chair 10, it returns to the primary disinfection tank 1 through the first pipe 9, realizing water circulation. This achieves the circulation of sterile water from the dual-stage electrolysis and photocatalysis. When automatically disinfecting the dental chair, there are no problems such as low disinfection efficiency, complicated operation, and easy water contamination.

[0025] The dual-stage electrolysis and photocatalytic synergistic disinfection equipment achieves highly efficient disinfection and continuous antibacterial effects in the water system through the synergistic action of an automatic water inlet system, a dual-stage disinfection system, and an automatic control system. The first-stage electrolysis cell electrolyzes tap water to generate hypochlorous acid, while the second-stage photocatalytic water tank uses ultraviolet light to excite the photocatalyst to generate hydroxyl radicals. The dual-stage synergistic disinfection efficiency is improved by more than 90%. The equipment features one-button start, automatic mode switching, and real-time residual chlorine monitoring. It solves the problems of low disinfection efficiency, complex operation, and water system contamination associated with traditional dental chairs, and is suitable for medical settings or scenarios requiring comprehensive disinfection and treatment of the water and pipelines used.

[0026] Working principle:

[0027] When using a dual-stage electrolysis and photocatalytic aseptic water circulation system for automated disinfection of dental chairs, both the first pipe 9 and the second pipe 11 are connected to the dental chair 10 via flanges. An external water source is connected to the inlet pipe 3, allowing the external water to enter the primary disinfection tank 1. The primary tank level controller 8 maintains the tap water level within the primary disinfection tank 1 at a certain height. The manual inlet valve 4 controls the opening and closing of the inlet pipe 3, and the inlet pressure sensor 5 monitors the water pressure inside the inlet pipe 3. The inlet solenoid valve 6 uses electromagnetic principles to control the opening and closing of the inlet pipe 3. The inlet filter 7 is a 0.5-micron filter that removes impurities from the tap water. The tap water enters the first-stage disinfection tank 2, where the electrolysis cell 2 electrolyzes the tap water. The electrolysis cell 2 is equipped with titanium-plated ruthenium-iridium anode rods and titanium cathode rods. The electrolysis of these titanium-plated ruthenium-iridium anode rods and titanium cathode rods achieves thorough disinfection of the dental chair. The electrolysis cell uses titanium-plated ruthenium-iridium anodes and titanium cathode rods, with a current density of 10-20 mA / cm². 2 Electrolysis generates hypochlorous acid (effective chlorine concentration 20-60 mg / L), with an electrolysis time of 1-3 minutes, killing 99.9% of bacteria and viruses;

[0028] Water from the primary disinfection tank 2 enters the secondary disinfection tank 15 through the fourth pipe 19. The titanium dioxide photocatalyst layer 17 and ultraviolet lamp 18 inside the secondary disinfection tank 16 further disinfect the tap water, achieving photocatalytic sterilization. The secondary tank level controller 16 maintains the tap water level in the secondary disinfection tank 15 within a certain range. The circulating water pump 13 is activated, drawing water from the secondary disinfection tank 15 through the third pipe 14 and pumping it into the dental chair 10 through the second pipe 11. The sterile water from the dual-stage electrolysis and photocatalysis enters the dental chair 10. The dental chair 10 is automatically disinfected inside. After the dental chair 10 is automatically disinfected inside, the water returns to the first disinfection tank 1 through the first pipe 9, realizing water circulation. This achieves a dual-stage electrolysis and photocatalytic sterile water circulation. When the dental chair is automatically disinfected, there are no problems such as low disinfection efficiency, complicated operation, and easy water contamination. The tap water in the second disinfection tank 15 is discharged through the first discharge pipe 20, and the tap water in the first disinfection tank 1 is discharged through the second discharge pipe 21. The dental chair 10 is then disassembled from the first pipe 9 and the second pipe 11.
