Description

Technical Field

[0001] The invention belongs to the technical field of sterilization and disinfection, and in particular relates to a plasma water channel disinfector for a comprehensive oral treatment table. Background Art

[0002] The comprehensive oral treatment unit is an important device for the diagnosis and treatment of dental diseases. Its water system consists of narrow and slender pipes, which are prone to breeding bacteria and forming biofilms. The biofilm has a special structure and is difficult to remove by conventional means. It can enter the patient's mouth with water or be transmitted through aerosols, causing cross-infection in the hospital.

[0003] Solutions in the existing technology include physical and chemical methods. Physical methods, such as centralized pure water supply, filtration or anti-backflow equipment, can only prevent foreign bacteria, but cannot solve the problem of old biofilms, and are prone to clogging and failure, with high maintenance costs; chemical methods, such as manual preparation of chlorine-containing disinfectants, installation of hypochlorous acid or ozone water disinfectors, etc., are cumbersome and pose safety hazards. Chlorine-containing disinfectants will corrode pipelines if used for a long time; installation of hypochlorous acid disinfectors requires regular addition of chemical reagents, and long-term use will pollute the environment due to chemical residues; installation of ozone water disinfectors can usually only be used for water flushing and disinfection, and cannot be used for daily diagnosis and treatment, because excessively high concentrations of ozone water will damage the human oral mucosa.

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0032] like Figures 1 to 2 FIG. 1 is a structural diagram of a plasma waterway disinfector for a dental comprehensive treatment table according to an embodiment of the present invention, comprising:

[0033] Housing 10;

[0034] A plasma discharge chamber 11 is provided in the housing 10 and is used to ionize air to generate active particles;

[0035] a high-voltage power supply 14 , disposed in the housing 10 and connected to the plasma discharge chamber 11 , to supply power to the plasma discharge chamber 11 ;

[0036] The plasma water treatment tank 6 is used to store unsterilized tap water. The active particles generated by the plasma discharge chamber 11 react with the tap water to produce activated water.

[0037] The semiconductor condensation reflux module 12 is provided in the housing 10 and connected between the plasma water treatment tank 6 and the plasma discharge chamber 11, and is used to dehumidify the airflow flowing out of the plasma water treatment tank 6;

[0038] An air pump is connected between the plasma discharge chamber 11 and the plasma water treatment tank 6, and is used to drive air flow through the plasma discharge chamber 11 to mix the active particles with the tap water;

[0039] The water storage tank 13 is disposed in the housing 10 and is connected to the plasma water treatment tank 6 for storing activated water.

[0040] In one embodiment of the present invention, the plasma water disinfector for a comprehensive oral treatment table is provided with a plasma discharge chamber 11, a semiconductor condensation reflux module 12, a water storage tank 13 and a high-voltage power supply 14 to address the problems raised in the prior art. The plasma water disinfector can ionize the air under high pressure to produce high-concentration active oxygen and active nitrogen particles. The airflow generated by the air pump flows through the discharge area, continuously mixing and reacting the high-concentration active oxygen and active nitrogen particles with tap water, thereby producing activated water rich in strong oxidizing substances such as hydrogen peroxide and ozone.

[0041] like Figure 3 As shown, as a preferred embodiment of the present invention, the plasma discharge chamber 11 includes:

[0042] Shell 1;

[0043] Shell 2 2 is sealed and connected to shell 1;

[0044] The discharge needle circuit board 3 and the ground electrode plate 4 are mounted on the housing 1 through the insulating bracket 5 and are used to ionize the air under high voltage to generate active oxygen and active nitrogen particles;

[0045] Specifically, a silicone sealing gasket is provided between the housing 1 and the housing 2;

[0046] Specifically, the discharge needle tip of the discharge needle circuit board 3 is tapered, and the ground electrode plate 4 is provided with an opening that matches the discharge needle tip.

[0047] The plasma discharge chamber 11 includes a shell 1 and a shell 2 that are fully welded by laser. A silicone sealing gasket is installed between the shell 1 and the shell 2 to prevent ozone leakage. The plasma electrode device consists of a discharge needle circuit board 3, a ground electrode plate 4 and an insulating bracket 5. In order to enhance the discharge intensity, the distance between the discharge needle circuit board 3 and the ground electrode plate 4 is controlled within 5-10 mm. The tip of the discharge needle of the discharge needle circuit board 3 is conical, and the radius is less than 0.1 mm. In order to stabilize the discharge, a high-voltage current-limiting resistor with a resistance of 1-100 MΩ and a power of 1-10 W is required to be connected in series between the discharge needle circuit board 3 and the high-voltage output end of the high-voltage power supply 14. At the same time, a hole is opened on the ground electrode plate 4 with the discharge needle tip as the center, and the aperture is 5-15 mm; the discharge needle circuit board 3 and the ground electrode plate 4 are fixed to the shell 1 by the insulating bracket 5. The insulating bracket 5 is preferably made of an insulating material with good insulation performance such as Teflon and nylon. The distance between the electrode device and the shell is not less than 20 mm;

[0048] During disinfection, the electrode device of the plasma discharge chamber 11 ionizes the air under high pressure to produce high-concentration active oxygen and active nitrogen particles. When the airflow generated by the air pump flows through the discharge area, the high-concentration active particles are continuously mixed and reacted with tap water, thereby producing activated water rich in strong oxidizing substances such as hydrogen peroxide and ozone. The activated water can destroy the cell structure of bacterial microorganisms or damage genetic material, thereby achieving sterilization and disinfection.

[0049] like Figure 4 As shown, as a preferred embodiment of the present invention, the semiconductor condensation reflux module 12 includes:

[0050] The condensation reflux housing 7 is installed at the opening of the plasma water treatment tank 6, and the condensation reflux housing 7 is provided with an air outlet 15 and a reflux hole 16;

[0051] The cold conducting plate 8 is mounted on the condensing reflux housing 7. One side of the cold conducting plate 8 is provided with a parallel spaced partition, and the other side is connected to the semiconductor refrigeration module 9.

[0052] Specifically, rectangular partitions are provided around the reflux hole 16 .

[0053] The semiconductor condensation reflux module 12 includes a condensation reflux housing 7, a cold plate 8 and a semiconductor refrigeration module 9. The plasma water treatment tank 6 stores tap water to be disinfected. The condensation reflux housing 7 is installed at the opening of the plasma water treatment tank 6. An air outlet 15 and a plurality of reflux holes 16 are provided on its surface. A rectangular partition is provided around the reflux hole 16. The distance from the bottom end of the partition to the bottom surface of the plasma water treatment tank 6 is 10 to 30 mm to prevent the aerated air flow from leaking out of the reflux hole. The cold plate 8 is made of metals such as aluminum alloy and copper alloy with high thermal conductivity. One side of the cold plate has a There are partitions arranged in parallel at intervals, and the other side is installed with the semiconductor refrigeration module 9. The cold conduction plate 8 is installed on the condensation reflux housing 7, which can form an S-shaped airflow channel; during disinfection, the surface temperature of the cold conduction plate 8 is close to zero degrees under the action of the semiconductor refrigeration module 9. The air flow with saturated water vapor flowing out of the activated water flows into the S-shaped channel from the air outlet 15, and condenses into droplets on the surface of the cold conduction plate 8, and then flows into the plasma water treatment water tank 6 from the reflux hole 16, thereby ensuring that the air flow entering the semiconductor condensation reflux module 12 will not condense into water droplets on the electrode surface and cause abnormal discharge.

[0054] When the plasma water disinfector is used in a comprehensive oral treatment unit, the logic flow is as follows: Figure 5 As shown, the specific process is:

[0055] Tap water flows into the product from the water inlet and is connected to the two-way solenoid valve. The plasma water treatment tank 6 is used to store tap water to be disinfected. A water level sensor 1 is installed at the highest liquid level. The water level sensor 2 is a pipeline water level sensor that can detect the lack of water in the plasma water treatment tank 6 in time. Water storage 13 is used to store activated water that has been disinfected by plasma. A water level sensor 3 is installed at the highest liquid level. The plasma discharge chamber 11, the air pump, the plasma water treatment tank 6 and the semiconductor condensation reflux module 12 together constitute a water treatment aeration circulation channel. During disinfection, the high-voltage power supply 14, the air pump and the semiconductor The cooling module 12 is turned on at the same time, and the electrode device in the plasma discharge chamber 11 ionizes the air under high pressure to produce high-concentration active oxygen and active nitrogen particles. The airflow generated by the air pump flows through the discharge area to continuously mix and react the high-concentration active particles with the tap water in the plasma water treatment tank 6, thereby producing activated water rich in strong oxidizing substances such as hydrogen peroxide and ozone. In order to avoid abnormal discharge caused by condensation on the surface of the electrode device, the airflow containing saturated water vapor flowing out of the plasma water treatment tank 6 must first pass through the semiconductor condensation reflux module 12 for dehumidification before returning to the plasma discharge chamber 11; when the pressure switch detects that the water pressure in the water channel is lower than When the pressure reaches the lower limit of the set pressure range, the booster pump starts to pump the water in the water tank 13 into the pipeline in the oral comprehensive treatment table. Once the liquid level in the water tank 13 is lower than the height set by the water level sensor 3, the self-priming pump starts immediately to pump the water in the plasma water treatment tank 6 into the water tank 13 until the liquid level in the water tank 13 rises to the height set by the water level sensor 3. When the liquid level in the water tank 13 reaches the scale set by the water level sensor 3, the self-priming pump stops working. As the working time increases, when the plasma water treatment tank 6 is in a water shortage state, that is, when the water level sensor detects water shortage, the solenoid valve is opened to fill water into the plasma water treatment tank 6. Until the height corresponding to the second water level sensor is reached, water is poured into the water tank while the high-voltage power supply 14, the air pump and the semiconductor refrigeration module 12 are started to disinfect the plasma water treatment tank 6. When the entire plasma water treatment time reaches the set value, the high-voltage power supply and the air pump are stopped, and whether to start the self-priming pump to fill the water tank 13 is determined according to the current water level of the water storage tank 13. During the entire plasma water disinfection period, the plasma water treatment tank 6 cannot fill the water storage tank 13. When the pressure switch detects that the water pressure in the water channel is higher than the upper limit of the set pressure range, the booster pump stops working. The flow meter is used to detect the water flow in the pipeline in real time.

[0056] There are two disinfection modes for the plasma water disinfector of the oral comprehensive treatment table. One is the daily medical water disinfection and antibacterial mode, which requires that the residual ozone in the water after disinfection should be less than 0.3 mg / L. Therefore, the plasma water disinfection time setting value cannot be too long, usually in the range of 5-10 minutes; the other is the water channel strong disinfection and flushing mode, which is used to disinfect the biofilm that may form on the surface of the oral comprehensive treatment table pipes, and is not used as medical water. Therefore, the plasma water disinfection time setting value is usually 20-40 minutes.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
