Please refer to FIG. 1, which is a schematic diagram of a cooperation structure of an oral medical device disinfection device provided by a specific embodiment of the present invention.

In a specific embodiment, the oral medical device disinfection device provided by the present invention includes a disinfection pipeline 11, a filter 111, an electrolysis device 112, a main storage tank 113, and a water pump 114 that are sequentially connected along the liquid flow direction on the disinfection pipeline 11. The upstream of the filter 111 is connected to the tap water supply equipment, the downstream of the water pump 114 is connected to the water pipeline of the oral medical equipment, the electrolytic device 112 is connected to the electrolyte storage tank 115, and the main storage tank 113 and the water pump 114 are connected to each other. Valve 116.

The filter 111 may include a replaceable filter, the filter may be an activated carbon filter containing coal-based activated carbon or coconut shell activated carbon, a PP (Polypropylene) fiber cotton filter, a resin filter, or Ceramic filter element sintered with diatomaceous earth.

Although the above-mentioned check valve 116 is a separate component from the water pump 114, in one embodiment, the check valve 116 may be built in the water pump 114, thereby further simplifying the composition and quantity of components on the disinfection pipeline 11. . Reduce the chance of individual components being exposed to the outside of the sterilization pipeline 11 and being easily damaged.

In yet another embodiment, the check valve 116 can be omitted, and the liquid in the disinfection pipeline 11 can be prevented from flowing backward only by the pressure difference between the upstream and downstream of the disinfection pipeline 11.

During the working process, the tap water is filtered by the filter 111 and then directly passed into the electrolytic device 112. At the same time, the electrolytic solution is passed through the electrolytic storage tank 115 into the electrolytic device 112, and then electrolysis is performed. After the electrolysis, a liquid containing hypochlorous acid is passed. After entering the main storage tank 113, the disinfection operation is performed in the pipeline to be sterilized by the pump 114 through the check valve 116 and the pump 114 to the inlet cavity medical equipment. Among them, hypochlorous acid produced after electrolysis has a strong oxidizing ability. After contacting with microorganisms, it can quickly destroy the cell membrane of harmful microorganisms, cause the death of microorganisms, and achieve the sterilization effect. The entire disinfection implementation process of the oral medical equipment disinfection device is simple, fast, and efficient. The disinfection effect is thorough, and no side effects or by-products are generated during the disinfection process, which ensures the cleanliness of the internal environment of the related equipment.

During actual work, the chloride ions in the electrolyte at the anode in the electrolytic device 112 are oxidized to generate chlorine gas. The main reaction formula is as follows:

2Cl- → Cl ₂ ＋ 2e-;

After that, the chlorine gas generated at the anode further reacts with water to form hypochlorous acid (HClO). The corresponding reaction formula is as follows:

Cl ₂ + H ₂ O → HClO + HCl.

Hypochloric acid produced after electrolysis has strong oxidizing ability. It can damage cell membranes after contact with microorganisms, so that proteins, RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) in the cell can not play normal biochemical activities and quickly destroy. The cell membrane of harmful microorganisms causes the death of microorganisms and achieves bactericidal effect.

Further, a direct supply line 12 is connected between the upstream water path of the filter 111 and the downstream water path of the water pump 114. The direct supply line 12 is connected in parallel with the sterilization line 11, and a solenoid valve 121 is provided on the direct supply line 12. When the electrolysis device 112 or other components on the sterilization pipeline 11 fail or cannot work normally, open the solenoid valve 121 and directly send the tap water from the tap water supply equipment to the water pipeline of the oral medical equipment through the direct supply pipeline 12 In order to ensure the normal use of water for clinical terminal equipment of oral medical equipment and the smooth implementation of corresponding medical operations. In more detail, the direct supply pipeline 12 and the disinfection pipeline 11 are branches of the upstream waterway. The disinfection pipeline 11 is directly connected to the filter 111, and the direct supply pipeline 12 is directly connected to the disinfection pipeline 11 downstream of the water pump 114. In the section, even if the upstream filter 111, electrolysis device 112, check valve 116, or water pump 114 fails, the direct supply line 12 can still supply water to the clinical terminal equipment through the opening of the solenoid valve 121.

In another embodiment, the downstream end of the direct supply line 12 may be directly connected to the sterilization line 11 section between the check valve 116 and the water pump 114. When the water pump 114 is operable, even the upstream The filter 111, the electrolytic device 112, or the check valve 116 fails, and the direct supply line 12 can still normally supply water to the clinical terminal equipment through the opening of the solenoid valve 121.

In yet another embodiment, the downstream end of the direct supply line 12 may be connected to the sterilization line 11 section between the main storage tank 113 and the check valve 116, and the water pump 114 and the check valve 116 may operate. In the situation, even if the upstream filter 111, the electrolysis device 112 or the check valve 116 fails, the direct supply pipeline 12 can still normally supply water to the clinical terminal equipment through the opening of the solenoid valve 121.

More specifically, a flow meter 117 is connected between the filter 111 and the electrolytic device 112. The flow meter 117 can efficiently adjust the amount of tap water flowing into the electrolysis device 112, and accordingly adjust the ratio of the electrolytic solution to the tap water in the electrolysis device 112, thereby making the preparation of hypochlorous acid water more accurate and controllable.

In addition, the electrolytic device 112 is a diaphragm-free electrolytic device, and an electrode of the electrolytic device 112 is a titanium-based Pt-Ir (platinum-iridium) electrode. This type of diaphragm-free electrolysis device generally has an electrolytic cell structure, which has high electrolysis efficiency and large preparation volume, and can further improve the working efficiency and disinfection effect of the oral medical equipment disinfection device.

On the other hand, the effluent pH of the electrolysis device is 5.0 to 6.5, and the effective chlorine concentration of the effluent is 10 to 40 ppm (parts per million concentration). The water parameters can effectively ensure the disinfection effect and operation efficiency.

In addition, a peristaltic pump (not shown in the figure) is provided in the electrolytic device 112 to cooperate with the electrolyte storage tank 115.
