Description

Technical Field

[0001] The present application relates to the technical field of dental medical equipment, and in particular to a small sterilizing autoclave for dentists. Background Art

[0002] Dental disease has become a common disease in people's lives. Due to physiological and cosmetic needs, more and more people go to hospitals and beauty clinics for dental treatment. During dental treatment, it is generally necessary to rinse the mouth with water, so the sanitary condition of the water system is directly related to the health and safety of the patient. In dental treatment, a water tank is generally used in combination with a water pump to transport water to multiple dental chairs to meet the oral rinsing needs during treatment. Because the pipelines of the water system are thin and long, air will enter the pipeline when the treatment is stopped, causing bacteria and viruses to grow on the inner wall of the pipeline. Bacteria and virus plaques that fall off from time to time enter the patient's mouth with water, which can easily cause infection in patients with wounds.

[0003] At present, the methods for disinfecting water pipelines mainly include ultraviolet disinfection and chemical dosing. Among them, ultraviolet disinfection has high requirements for water volume, and needs to control the water volume in the pipeline to be small, and also has certain requirements for the uniformity of water flow. The agents added by the chemical dosing method need to undergo relevant oral toxicity tests to ensure that they will not cause additional damage to the human body, such as hypochlorous acid disinfectant.

[0004] However, in actual use, it is often difficult to achieve precise control of the water volume and uniformity of the water flow, resulting in poor disinfection effects of ultraviolet disinfection; and hypochlorous acid disinfectants are unstable and can easily become ineffective after long-term storage, affecting the disinfection effect, which in turn results in poor disinfection effects on water pipelines.

[0005] The above-mentioned related technologies have the defect of poor disinfection effect on dental treatment water pipelines. Summary of the invention

[0006] In order to improve the problem of poor disinfection effect of dental treatment water pipelines, the present application provides a small disinfection kettle for dentists.

[0007] The small-sized sterilizing kettle for dentists provided in this application adopts the following technical solution: A small dental sterilizer is provided on one side of a dental chair. The small dental sterilizer includes: a carbon dioxide output mechanism that holds carbon dioxide gas; a sodium hypochlorite output mechanism that holds a sodium hypochlorite solution; a reaction kettle. The carbon dioxide output mechanism is provided below the reaction kettle, and the carbon dioxide output mechanism communicates with the lower end of the reaction kettle for delivering carbon dioxide gas into the reaction kettle from bottom to top. The sodium hypochlorite output mechanism is provided above the reaction kettle, and the sodium hypochlorite output mechanism communicates with the upper end of the reaction kettle for delivering the sodium hypochlorite solution into the reaction kettle from top to bottom; a conveying mechanism. The conveying mechanism includes an input component and an output component. The input component and the output component are respectively provided on both sides of the reaction kettle. The input component is used to input water into the reaction kettle. The first end of the output component is connected to the reaction kettle, and the second end of the output component is connected to a rinsing mechanism on one side of the dental chair for rinsing the oral cavity. The output component is used to convey the mixed liquid in the reaction kettle to the rinsing mechanism; an adjusting mechanism. The adjusting mechanism is provided inside the reaction kettle. The adjusting mechanism includes a baffle and a reset driving member. The baffle is slidably connected to the reaction kettle. One side of the baffle faces the output end of the input component, and the baffle is spaced from the output end of the input component. The baffle is used to block the water flow output by the input component. The first end of the reset driving member is connected to the reaction kettle, and the second end of the reset driving member is connected to the baffle. The reset driving member is used to drive the baffle to reset.

[0008] By adopting the above technical solution, the problem that bacteria and viruses are likely to breed in dental water can be effectively solved. The carbon dioxide output mechanism and the sodium hypochlorite output mechanism respectively deliver carbon dioxide gas and sodium hypochlorite solution into the reaction kettle, and water is input into the reaction kettle through the input component, so that carbon dioxide and sodium hypochlorite react chemically in water to generate a hypochlorous acid solution with bactericidal and disinfectant effects, reducing the risk of bacteria and viruses entering the patient's oral cavity with the water flow and causing infection; the reaction kettle provides a space for the reaction of carbon dioxide and sodium hypochlorite. The conveying mechanism arranges the input component and the output component on both sides of the reaction kettle, realizing the complete process of water input, generation of the mixed liquid, and delivery to the rinsing mechanism, ensuring that the disinfected water can be promptly used for dental treatment; the baffle and the reset driving member in the adjusting mechanism can be dynamically adjusted according to the water flow situation, effectively blocking the water flow output by the input component, reducing the risk of the water flow flowing out of the reaction kettle too quickly due to the too high flow rate of the water flow input into the reaction kettle, extending the flow path of the water flow in the reaction kettle, increasing the reaction rate in the reaction kettle, alleviating the problem of the decline in mixing uniformity. At the same time, making the water flow relatively slow can also extend the time for different substances to contact and react with each other, helping to enhance the sterilization effect; and because the baffle can move slowly under the action of the water flow push, it helps to provide an auxiliary stirring effect and make the chemical reaction more complete.

[0009] Optionally, the adjusting mechanism includes a first guide member, a second guide member, a first reset member, and a second reset member. The first guide member is disposed above the baffle, and the second guide member is disposed below the baffle. The upper end of the baffle abuts against the lower side of the first guide member, and the lower end of the baffle abuts against the upper side of the second guide member. Both the first guide member and the second guide member are slidably connected to the reaction kettle. Both the first guide member and the second guide member are inclined, and the inclination directions of the first guide member and the second guide member are opposite, so that the vertical distance between the first guide member and the second guide member at the end close to the input assembly is greater than the vertical distance between the first guide member and the second guide member at the end far from the input assembly. The first reset member is disposed on the side of the first guide member away from the baffle, and the first reset member is used to push the first guide member downward to reset. The second reset member is disposed on the side of the second guide member away from the baffle, and the second reset member is used to push the second guide member upward to reset.

[0010] By adopting the above technical solution, the upper end of the baffle abuts against the lower side of the first guide member, and the lower end abuts against the upper side of the second guide member. The inclination directions of the first guide member and the second guide member are opposite, so that the vertical distance at the end close to the input assembly is greater than the vertical distance at the end far from the input assembly. When the water flow impacts the baffle, the baffle drives the first guide member and the second guide member to slide, extending the water flow path and reducing the flow rate, which helps to enhance the water flow mixing effect. The first reset member pushes the first guide member downward to reset, and the second reset member pushes the second guide member upward to reset, enabling the baffle to repeatedly adjust its position, further improving the mixing efficiency, thereby effectively improving the mixing uniformity of the sodium hypochlorite solution and the carbon dioxide gas, and ensuring that the generated disinfectant has a stable bactericidal effect.

[0011] Optionally, the adjusting mechanism includes a first impeller and a second impeller. Both the first impeller and the second impeller are rotatably connected to the reaction kettle. The first impeller and the second impeller are horizontally disposed between the input assembly and the baffle. The first impeller cooperates with the first guide member to make the liquid in the reaction kettle flow along the first guide member towards the first impeller, driving the first impeller to rotate. The second impeller cooperates with the second guide member to make the liquid in the reaction kettle flow along the second guide member towards the second impeller, driving the second impeller to rotate.

[0012] By adopting the above technical solution, the first impeller cooperates with the first guide member, enabling the liquid to flow towards the first impeller along the first guide member and driving the first impeller to rotate, thereby enhancing the mixing effect of the liquid; the second impeller cooperates with the second guide member, enabling the liquid to flow towards the second impeller along the second guide member and driving the second impeller to rotate, further improving the mixing uniformity of the liquid. This design creates a turbulent flow inside the reaction kettle, which helps to enhance the dispersion degree of carbon dioxide gas and sodium hypochlorite solution in water, promotes the chemical reaction among the three, and thus improves the disinfection effect.

[0013] Optionally, the carbon dioxide output mechanism includes a lower bearing box, a gas cylinder, a lower connecting member, and a plurality of lower spraying members. The lower bearing box is arranged below the reaction kettle. The gas cylinder is used to store carbon dioxide and is detachably placed in the lower bearing box. The first end of the lower connecting member is detachably connected to the output end of the gas cylinder. The second end of the lower connecting member is provided with a plurality of the lower spraying members, which are correspondingly arranged with the second end of the lower connecting member. The lower spraying members are correspondingly connected to the second end of the lower connecting member. The plurality of lower spraying members are evenly distributed at the lower end of the reaction kettle, so that the carbon dioxide in the gas cylinder is evenly sprayed into the reaction kettle.

[0014] By adopting the above technical solution, the uniform spraying of carbon dioxide inside the reaction kettle is realized. The gas cylinder can be detachably placed in the lower bearing box, which is convenient for replacement and maintenance; the detachable connection design between the lower connecting member and the output end of the gas cylinder improves the assembly flexibility; the plurality of lower spraying members are evenly distributed at the lower end of the reaction kettle, ensuring that the carbon dioxide gas can fully cover the inside of the reaction kettle in all directions, thereby effectively promoting its full mixing with the sodium hypochlorite solution and improving the disinfection effect.

[0015] Optionally, the sodium hypochlorite output mechanism includes an upper bearing box, a containing member, an upper connecting member, and a plurality of upper spraying members. The upper bearing box is arranged above the reaction kettle. The containing member is used to store sodium hypochlorite and is detachably arranged in the upper bearing box. The first end of the upper connecting member is connected to the output end of the containing member. The second end of the upper connecting member is provided with a plurality of the upper spraying members, which are correspondingly arranged with the second end of the upper connecting member. The upper spraying members are correspondingly connected to the second end of the upper connecting member. The plurality of upper connecting members are evenly distributed at the upper end of the reaction kettle, so that the sodium hypochlorite in the containing member is evenly sprayed into the reaction kettle.

[0016] By adopting the above technical solution, the uniform spraying of sodium hypochlorite in the reaction kettle can be achieved. The setting of the upper bearing box provides a stable placement position for the accommodating member, ensuring the smooth and reliable storage and output process of the sodium hypochlorite solution; the detachable design of the accommodating member facilitates the replacement and replenishment of the sodium hypochlorite solution, improving the maintenance convenience of the equipment; the cooperation between the upper connecting member and several upper spraying members enables the sodium hypochlorite solution to be evenly sprayed into the reaction kettle, improving the mixing efficiency and disinfection effect.

[0017] Optionally, at least one of the upper spraying members sprays towards the same side of the first impeller to assist in driving the rotation of the first impeller; at least one of the lower spraying members sprays towards the same side of the second impeller to assist in driving the rotation of the second impeller.

[0018] By adopting the above technical solution, at least one upper spraying member sprays the sodium hypochlorite solution towards the first impeller, which can provide additional driving force for the first impeller, enhance the rotation effect of the first impeller, and improve the mixing efficiency. At the same time, at least one lower spraying member sprays carbon dioxide gas towards the second impeller, which can also assist in driving the rotation of the second impeller, ensuring the full mixing of carbon dioxide gas and sodium hypochlorite solution, and enhancing the disinfection effect.

[0019] Optionally, the accommodating member is provided with a feeding port.

[0020] By adopting the above technical solution, the setting of the feeding port makes the replenishment of the sodium hypochlorite solution more convenient. The feeding operation can be realized without disassembling the accommodating member, improving the use convenience of the equipment, and ensuring the sufficient supply of the disinfectant solution, thus ensuring the continuous and stable disinfection effect.

[0021] Optionally, the adjusting mechanism includes several spoiler columns, the spoiler columns are arranged in the reaction kettle, and the spoiler columns are distributed between the baffle and the first end of the output assembly.

[0022] By adopting the above technical solution, the setting of the spoiler columns can effectively change the flow direction and velocity distribution of the liquid in the reaction kettle. Specifically, the spoiler columns are distributed between the baffle and the first end of the output assembly, which can block and guide the water flow, making the water flow form a more complex flow path in the reaction kettle, thereby increasing the mixing efficiency between carbon dioxide gas and sodium hypochlorite solution. This efficient mixing process helps to generate a more stable hypochlorous acid solution, thereby improving the killing effect on bacteria and viruses in water and ensuring higher hygienic safety of the water finally delivered to the dental chair flushing mechanism.

[0023] Optionally, the adjusting mechanism includes several inclined plates, the inclined plates are connected to the reaction kettle, several of the inclined plates are distributed between the baffle and the first end of the output assembly, the inclination directions of adjacent inclined plates are opposite, and adjacent inclined plates are arranged in a vertically staggered manner.

[0024] By adopting the above technical solution, the setting of the inclined plate can effectively guide the flow direction of the liquid in the reaction kettle, causing the liquid to generate a turbulent flow effect when flowing through the inclined plate, thereby enhancing the liquid mixing effect. The opposite inclination directions of adjacent inclined plates and the vertical dislocation setting further increase the complexity of the liquid flow, ensuring that the carbon dioxide gas and the sodium hypochlorite solution are fully contacted and react to generate a sodium hypochlorite solution with a disinfection effect.

[0025] Optionally, the conveying mechanism includes a water conveying component. The first end of the water conveying component is connected to the input end of the input component, and the second end of the water conveying component is connected to the flushing mechanism. The water conveying component is used to input water into the flushing mechanism.

[0026] By adopting the above technical solution, it is possible to guide the water from the input component to the flushing mechanism, ensuring that the water flow is stably conveyed to the flushing mechanism on one side of the dental chair, thereby providing necessary water source support for the treatment of patients.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the synergistic effect of the carbon dioxide output mechanism and the sodium hypochlorite output mechanism, a highly efficient disinfectant is generated in the reaction kettle, which can effectively kill bacteria and viruses in water, reduce the growth of biological plaques in the pipeline, and reduce the risk of patient infection; 2. The baffle and the reset driving member in the adjusting mechanism cooperate with the change of the water flow to realize the adjustment of the water flow speed and direction, improve the mixing uniformity, and enhance the disinfection effect.

[0034] As Figure 1 、 Figure 2 and Figure 3 As shown in

[0035] The carbon dioxide output mechanism 1 holds carbon dioxide gas. The carbon dioxide output mechanism 1 is arranged below the reaction kettle 3. The carbon dioxide output mechanism 1 is connected to the lower end of the reaction kettle 3 and is used to transport carbon dioxide gas into the reaction kettle 3 from bottom to top. The sodium hypochlorite output mechanism 2 holds sodium hypochlorite solution. The sodium hypochlorite output mechanism 2 is arranged above the reaction kettle 3. The sodium hypochlorite output mechanism 2 is connected to the upper end of the reaction kettle 3 and is used to transport sodium hypochlorite solution into the reaction kettle 3 from top to bottom. The conveying mechanism 4 includes an input component 41 and an output component 42. The input component 41 and the output component 42 are respectively arranged on both sides of the reaction kettle 3. The input component 41 is used to input water into the reaction kettle 3. The first end of the output component 42 is connected to the reaction kettle 3, and the second end of the output component 42 is connected to a rinsing mechanism 200 on one side of the dental chair 100 for rinsing the oral cavity. The output component 42 is used to transport the mixed liquid in the reaction kettle 3 to the rinsing mechanism 200. The adjusting mechanism 5 is arranged in the reaction kettle 3. The adjusting mechanism 5 includes a baffle 511 and a reset driving member 512. The baffle 511 is slidably connected to the reaction kettle 3. One side of the baffle 511 faces the output end of the input component 41, and the baffle 511 is spaced from the output end of the input component 41. The baffle 511 is used to block the water flow output by the input component 41. The reset driving member 512 is used to drive the baffle 511 to reset. The first end of the reset driving member 512 is connected to the reaction kettle 3, and the second end of the reset driving member 512 is connected to the side of the baffle 511 away from the input component 41, so that the baffle 511 can move horizontally in a direction close to or away from the output end of the input component 41. The input component 41 includes an input pipeline 411, and the output component 42 includes an output pipeline 421.

[0036] Such as Figure 1 , Figure 2 and Figure 3As shown, by utilizing the effect of NaClO + CO2 + H2O → HClO + NaHCO3, sodium hypochlorite (NaClO) undergoes a chemical reaction with carbon dioxide and water to produce hypochlorous acid (HClO) and sodium bicarbonate (NaHCO3). Sodium bicarbonate is harmless to the human body and can be used together with hypochlorous acid. That is, by mixing and reacting sodium hypochlorite, carbon dioxide, and water, a 5 ppm concentration of hypochlorous acid disinfectant is prepared on-site for use by dentists and patients. Carbon dioxide gas and sodium hypochlorite solution are respectively transported into the reaction kettle 3 through the carbon dioxide output mechanism 1 and the sodium hypochlorite output mechanism 2, and water is input into the reaction kettle 3 through the input component 41, enabling carbon dioxide and sodium hypochlorite to undergo a chemical reaction in water to generate a hypochlorous acid solution with bactericidal and disinfectant effects, reducing the risk of bacteria and viruses entering the patient's oral cavity with the water flow and causing infection. The reaction kettle 3 provides a space for the reaction of carbon dioxide and sodium hypochlorite. The conveying mechanism 4 separates the input component 41 and the output component 42 on both sides of the reaction kettle 3, realizing the complete process of water input, generation of the mixed solution, and transportation to the flushing mechanism 200, ensuring that the disinfected water can be promptly used for dental treatment. The baffle 511 and the reset driving part 512 in the adjusting mechanism 5 can be dynamically adjusted according to the water flow situation, effectively blocking the water flow output by the input component 41, reducing the risk of the water flow flowing out of the reaction kettle 3 too quickly due to the too high flow rate of the water flow input into the reaction kettle 3, extending the flow path of the water flow in the reaction kettle 3, increasing the reaction rate in the reaction kettle 3, and alleviating the problem of the decline in mixing uniformity. At the same time, making the water flow relatively slow can also extend the time for different substances to come into contact and react with each other, helping to enhance the bactericidal effect; moreover, since the baffle 511 can move slowly under the pushing action of the water flow, it helps to provide an auxiliary stirring effect, making the chemical reaction more complete.

[0037] As Figure 1 , Figure 2 and Figure 3 shown, optionally, the carbon dioxide output mechanism 1 includes a lower bearing box 11, a gas cylinder 12, a lower connecting piece 13, and a plurality of lower spraying parts 14. The lower bearing box 11 is arranged below the reaction kettle 3, and the gas cylinder 12 is used to store carbon dioxide. The gas cylinder 12 is detachably placed in the lower bearing box 11, which is convenient for replacement and maintenance. The first end of the lower connecting piece 13 is detachably connected to the output end of the gas cylinder 12, improving the assembly flexibility. A plurality of second ends are provided at the second end of the lower connecting piece 13, and the lower spraying parts 14 are correspondingly arranged with the second end of the lower connecting piece 13. The lower spraying parts 14 are correspondingly connected to the second end of the lower connecting piece 13, and the plurality of lower spraying parts 14 are evenly distributed at the lower end of the reaction kettle 3, enabling the carbon dioxide in the gas cylinder 12 to be evenly sprayed into the reaction kettle 3. The plurality of lower spraying parts 14 are evenly distributed at the lower end of the reaction kettle 3, ensuring that the carbon dioxide gas can fully cover the inside of the reaction kettle 3 in all directions, thereby effectively promoting its full mixing with the sodium hypochlorite solution and improving the disinfection effect.

[0038] AsFigure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , optionally, the sodium hypochlorite output mechanism 2 includes an upper carrier box 21, a container 22, an upper connecting piece 23 and a plurality of upper spraying pieces 24. The upper carrier box 21 is arranged above the reaction kettle 3, and the container 22 is used for storing sodium hypochlorite. The setting of the upper carrier box 21 provides a stable placement position for the container 22, ensuring the stable and reliable storage and output process of the sodium hypochlorite solution. A water pump 25 can be arranged in the container 22 to facilitate the output of the sodium hypochlorite solution in the container 22. The container 22 is detachably arranged in the upper carrier box 21, which is convenient for replacing and supplementing the sodium hypochlorite solution, improving the maintenance convenience of the equipment. The first end of the upper connecting piece 23 is connected to the output end of the container 22. The upper connecting piece 23 is provided with a plurality of second ends. The upper spraying pieces 24 are correspondingly arranged with the second ends of the upper connecting piece 23. The upper spraying pieces 24 are correspondingly connected to the second ends of the upper connecting piece 23. The plurality of upper connecting pieces 23 are evenly distributed at the upper end of the reaction kettle 3, so that the sodium hypochlorite in the container 22 is evenly sprayed into the reaction kettle 3, improving the mixing efficiency and disinfection effect. The upper connecting piece 23 and the lower connecting piece 13 can both be pipelines; the upper spraying pieces 24 and the lower spraying pieces 14 are both nozzles; according to the use requirements, a small amount of HCL can also be added into the container 22.

[0039] Optionally, the container 22 is provided with a feeding port 221. The setting of the feeding port 221 makes the supplement of the sodium hypochlorite solution more convenient. The feeding operation can be realized without disassembling the container 22, improving the use convenience of the equipment. At the same time, it ensures the sufficient supply of the disinfectant solution, thus ensuring the continuous and stable disinfection effect.

[0040] As Figure 1 , Figure 2 and Figure 3As shown, optionally, the adjusting mechanism 5 includes a first guiding member 521, a second guiding member 522, a first restoring member 523 and a second restoring member 524. The first guiding member 521 is disposed above the baffle 511, and the upper end of the baffle 511 abuts against the lower side of the first guiding member 521; the second guiding member 522 is disposed below the baffle 511, and the lower end of the baffle 511 abuts against the upper side of the second guiding member 522. Both the first guiding member 521 and the second guiding member 522 are slidably connected to the reaction kettle 3. Both the first guiding member 521 and the second guiding member 522 are inclined, and the inclination directions of the first guiding member 521 and the second guiding member 522 are opposite, so that the vertical distance between the first guiding member 521 and the second guiding member 522 at the end close to the input assembly 41 is greater than the vertical distance between the first guiding member 521 and the second guiding member 522 at the end far from the input assembly 41. The first restoring member 523 is disposed on the side of the first guiding member 521 away from the baffle 511, and the first restoring member 523 is used to push the first guiding member 521 to move downward for resetting; the second restoring member 524 is disposed on the side of the second guiding member 522 away from the baffle 511, and the second restoring member 524 is used to push the second guiding member 522 to move upward for resetting. A plurality of sliding rails are provided in the reaction kettle 3, and the baffle 511, the first guiding member 521 and the second guiding member 522 are all slidably connected to the corresponding sliding rails, so that the baffle 511 slides horizontally, and the first guiding member 521 and the second guiding member 522 both slide vertically. The first guiding member 521 and the second guiding member 522 are in the shape of plates; the reset driving member 512, the first restoring member 523 and the second restoring member 524 can all be springs.

[0041] When the water flow impacts the baffle 511, the horizontal movement of the baffle 511 drives the first guiding member 521 and the second guiding member 522 to slide vertically in opposite directions, changing the water flow direction, extending the water flow path, reducing the flow rate, and helping to enhance the water flow mixing effect. The first restoring member 523 pushes the first guiding member 521 to move downward for resetting, and the second restoring member 524 pushes the second guiding member 522 to move upward for resetting, so that the baffle 511 can repeatedly adjust its position, playing a certain stirring role, further improving the mixing efficiency, thereby effectively improving the mixing uniformity of the sodium hypochlorite solution and the carbon dioxide gas, and being used in time to ensure that the generated disinfectant has a stable bactericidal effect.

[0042] Such as Figure 1 、 Figure 2 and Figure 3As shown, optionally, the adjusting mechanism 5 includes a first impeller 531 and a second impeller 532. Both the first impeller 531 and the second impeller 532 are rotatably connected to the reaction kettle 3. The first impeller 531 and the second impeller 532 are horizontally arranged between the input assembly 41 and the baffle 511. The first impeller 531 cooperates with the first guide member 521 to make the liquid in the reaction kettle 3 flow towards the first impeller 531 along the first guide member 521, driving the first impeller 531 to rotate; the second impeller 532 cooperates with the second guide member 522 to make the liquid in the reaction kettle 3 flow towards the second impeller 532 along the second guide member 522, driving the second impeller 532 to rotate.

[0043] The first impeller 531 cooperates with the first guide member 521 to make the liquid flow towards the first impeller 531 along the first guide member 521 and drive the first impeller 531 to rotate, thereby enhancing the mixing effect of the liquid. The second impeller 532 cooperates with the second guide member 522 to make the liquid flow towards the second impeller 532 along the second guide member 522 and drive the second impeller 532 to rotate, further improving the mixing uniformity of the liquid. This design creates a turbulent flow in the reaction kettle 3, which helps to improve the dispersion degree of carbon dioxide gas and sodium hypochlorite solution in water and promotes the chemical reaction among the three, thereby improving the disinfection effect.

[0044] As Figure 1 , Figure 2 and Figure 3 shown, optionally, at least one upper jet member 24 jets towards the same side of the first impeller 531 to assist in driving the first impeller 531 to rotate, and the jet directions of the other upper jet members 24 do not contact the first impeller 531. At least one lower jet member 14 jets towards the same side of the second impeller 532 to assist in driving the second impeller 532 to rotate, and the jet directions of the other lower jet members 14 do not contact the second impeller 532 to avoid causing rotational resistance. That is, the upper jet members 24 that impact the first impeller 531 all impact the same side of the rotation center of the first impeller 531, and the lower jet members 14 that impact the second impeller 532 all impact the same side of the rotation center of the second impeller 532, which can provide additional driving force for the first impeller 531 and the second impeller 532, enhance the rotation effect of the first impeller 531 and the second impeller 532, improve the mixing effect, ensure the full mixing of carbon dioxide gas and sodium hypochlorite solution, and enhance the disinfection effect.

[0045] Optionally, the adjusting mechanism 5 includes a plurality of spoiler columns 54. The spoiler columns 54 are arranged inside the reaction kettle 3 and are distributed between the baffle 511 and the first end of the output assembly 42. The arrangement of the spoiler columns 54 can effectively change the flow direction and velocity distribution of the liquid inside the reaction kettle 3. The plurality of spoiler columns 54 can be arranged corresponding to the upper injection member 24 and the lower injection member 14, so that the carbon dioxide and sodium hypochlorite injection flows injected into the reaction kettle 3 are disturbed, improving the mixing uniformity. The spoiler columns 54 are distributed between the baffle 511 and the first end of the output assembly 42, and can block and guide the water flow, causing the water flow to form a more complex flow path inside the reaction kettle 3, thereby increasing the mixing efficiency between the carbon dioxide gas and the sodium hypochlorite solution. This efficient mixing process helps to generate a more stable sodium hypochlorite solution, thereby improving the killing effect on bacteria and viruses in water and ensuring that the water finally delivered to the rinsing mechanism 200 of the dental chair 100 has higher hygienic safety.

[0046] As Figure 1 , Figure 2 and Figure 3 shown, optionally, the adjusting mechanism 5 includes a plurality of inclined plates 55. The inclined plates 55 are connected to the reaction kettle 3. The plurality of inclined plates 55 are distributed between the baffle 511 and the first end of the output assembly 42. The inclination directions of adjacent inclined plates 55 are opposite, and adjacent inclined plates 55 are arranged vertically offset, and the plurality of inclined plates 55 can be distributed in a fishbone shape.

[0047] The spoiler columns 54 are distributed above and below the inclined plates 55. The arrangement of the spoiler columns 54 and the inclined plates 55 can effectively guide the flow direction of the liquid inside the reaction kettle 3, causing the liquid to generate a turbulent flow effect when flowing through the inclined plates 55, thereby enhancing the liquid mixing effect. The opposite inclination directions and vertical offset arrangement of adjacent inclined plates 55 further increase the complexity of the liquid flow, ensuring that the carbon dioxide gas and the sodium hypochlorite solution are fully contacted and react to generate a sodium hypochlorite solution with a disinfection effect.

[0048] As Figure 1 , Figure 2 and Figure 3 shown, optionally, the conveying mechanism 4 includes a water conveying assembly 43. The first end of the water conveying assembly 43 is connected to the input end of the input assembly 41, and the second end of the water conveying assembly 43 is connected to the rinsing mechanism 200. The water conveying assembly 43 is used to input water into the rinsing mechanism 200. The conveying mechanism 4 can realize guiding the water from the input assembly 41 to the rinsing mechanism 200, ensuring that the water flow is stably conveyed to the rinsing mechanism 200 on one side of the dental chair 100, thereby providing necessary water source support for the patient during treatment. In this embodiment, one end of the input pipeline 411 is connected to the water storage structure, and the other end is connected to the reaction kettle 3. The water conveying assembly 43 includes a water conveying pipeline 431, one end of which is connected to the water storage structure, and the other end is connected to the rinsing mechanism 200.

[0049] AsFigure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , in this embodiment, the sterilization kettle further includes necessary control valves, including but not limited to a carbon dioxide control valve 15, an input control valve 412 and a water supply control valve 432. The carbon dioxide control valve 15 is used to control the output of carbon dioxide in the gas cylinder 12; the input control valve 412 is arranged on the input pipeline 411 and is used to control whether the input component 41 inputs water into the reaction kettle 3, and the water supply control valve 432 is arranged on the water supply pipeline 431 and is used to control whether to directly supply water to the flushing mechanism 200. The sterilization kettle may further include a plurality of flow meters to accurately measure the flow rates of carbon dioxide, sodium hypochlorite and water input into the reaction kettle 3 respectively, so as to control the concentration of the obtained sodium hypochlorite disinfectant solution. A flow regulating valve may also be provided to facilitate the adjustment of the concentration of the disinfectant solution. The valve bodies of the carbon dioxide control valve 15, the input control valve 412 and the water supply control valve 432 are not limited in type, and appropriate solenoid valves or other different types of valve bodies can be selected according to needs. A control member, such as a two-way twisting faucet, is provided at the flushing mechanism 200, and it can be selected to make the outlet water be clean water or disinfectant according to needs, and the control principle is not limited. Through the setting of the above control structure, it is ensured that the input amounts of various materials can be accurately controlled according to the needs of doctors, and the quality and immediate supply of the disinfectant solution are ensured.

[0050] It can be understood that the sterilization kettle further includes necessary structures for functions such as connection, support, drive, positioning, limit, sealing and control, so that the sterilization kettle can operate normally; parameters such as the shape, size, material and setting quantity of each part of the sterilization kettle can be determined according to needs, as long as the corresponding functions can be realized.

[0051] The implementation principle of a small dental sterilization kettle in an embodiment of the present application is as follows: Carbon dioxide gas and sodium hypochlorite solution are respectively transported into the reaction kettle 3 through the carbon dioxide output mechanism 1 and the sodium hypochlorite output mechanism 2, and water is input into the reaction kettle 3 through the input component 41, so that carbon dioxide and sodium hypochlorite react chemically in water to generate a sodium hypochlorite solution with a bactericidal and disinfecting effect, reducing the risk of bacteria and viruses entering the patient's oral cavity with the water flow and causing infection; the baffle and the reset driving member in the adjusting mechanism can be dynamically adjusted according to the water flow situation, effectively blocking the water flow output by the input component, reducing the risk that the water flow input into the reaction kettle flows out of the reaction kettle too fast due to the too high flow rate of the water flow input into the reaction kettle and cannot react sufficiently, extending the flow path of the water flow in the reaction kettle, increasing the reaction rate in the reaction kettle, alleviating the problem of the decline in mixing uniformity, and helping to enhance the sterilization effect; and, since the baffle can move slowly under the pushing action of the water flow, it helps to provide an auxiliary stirring effect and make the chemical reaction more sufficient.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
