Description

Technical Field

[0001] This utility model relates to the field of medical ozone generation technology, specifically to a medical ozone discharge cavity. Background Technology

[0002] The medical ozone discharge tube is the core component of a medical ozone generator. Its main function is to allow dry oxygen or air to undergo an ionization reaction within the tube through specific discharge methods, such as surface discharge or gap discharge, and decompose it to generate ozone with medical uses. It is the key carrier for realizing the "oxygen → ozone" conversion in a medical ozone discharge tube.

[0003] Currently, although some discharge cavities are equipped with simple heat dissipation structures, they are mostly single flat or straight toothed heat sinks, which have problems such as limited heat dissipation contact area, poor air circulation, and low heat transfer efficiency. They are difficult to meet the heat dissipation requirements under continuous discharge conditions. Especially in medical scenarios where ozone concentration stability is required, the shortcomings of existing heat dissipation structures will significantly affect the reliability and performance of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a medical ozone discharge cavity to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a medical ozone discharge cavity, including an external electrode. The outer wall of the external electrode is provided with multiple heat dissipation components. The top of the heat dissipation component is provided with a toothed barrier. The bottom of the groove is formed between two adjacent heat dissipation components and the bottom of the groove. The portion of the two heat dissipation components near the toothed barrier is provided as a widening groove. A narrowing opening is formed between the toothed barriers. The top recessed portion of the toothed barrier is provided with multiple arc-shaped grooves.

[0006] Furthermore, a dielectric ceramic tube is installed on the inner wall of the tank bottom, and an oxygen channel is provided on the side of the dielectric ceramic tube away from the external electrode, and an internal electrode is provided on the side of the oxygen channel away from the dielectric ceramic tube.

[0007] Furthermore, the material of the internal electrode is set as titanium alloy stainless steel.

[0008] Furthermore, the heat sink is made of aluminum alloy.

[0009] Furthermore, a first sealing plug is provided at one end of the dielectric ceramic tube, and an ozone outlet pipe is provided at the top of the first sealing plug.

[0010] Furthermore, a second sealing plug is fixedly installed at the other end of the dielectric ceramic tube, and an oxygen inlet pipe is fixedly installed on the outer wall of the second sealing plug, with the other end of the oxygen inlet pipe extending into the interior of the oxygen channel.

[0011] Furthermore, the heat dissipation components are arranged in a ring-shaped uniform arrangement on the outer wall of the outer electrode.

[0012] Furthermore, the width of the groove bottom is less than the width of the widening groove, and the width of the widening groove is greater than the width of the toothed barrier.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. In this invention, a high voltage is applied to the inner and outer electrodes, forming a discharge electric field through a dielectric ceramic tube. Oxygen ionizes in the oxygen channel to generate ozone, and the outer electrode continuously generates heat during this process. Multiple heat sinks on the outer wall of the outer electrode rapidly conduct heat to themselves. Adjacent heat sinks, the bottom of the groove, the widened groove, and the narrowed opening form an airflow channel, allowing external air to enter. The arc-shaped groove and recessed inner toothed groove structure at the top of the toothed barrier increase the contact area between the heat sink and the air, allowing the air to fully contact the heat sink and carry away heat, achieving continuous heat dissipation and preventing the high temperature of the tube cavity from affecting ozone generation.

[0014] 2. In this utility model, the dielectric ceramic tube installed on the inner wall of the tank bottom, with its insulation properties, prevents short circuits between the inner and outer electrodes, helping them to stably form a high-voltage electric field and ensuring the continuous progress of the oxygen ionization reaction; the oxygen channel on the side of the dielectric ceramic tube away from the outer electrode is located between the inner electrode and the dielectric ceramic tube, in the core area of ​​the high-voltage electric field, allowing oxygen to directly contact the electric field and reducing its stay in non-electric field areas, and the channel guides the orderly flow of oxygen, avoiding uneven distribution that affects the reaction efficiency; the inner electrode on the side of the oxygen channel away from the dielectric ceramic tube is closer to the channel, which can strengthen the effect of the electric field on oxygen and ensure that oxygen is fully ionized to generate ozone.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 This utility model provides a technical solution: See Figures 1-5 As shown, a medical ozone discharge cavity includes an external electrode 4. The outer wall of the external electrode 4 is provided with a plurality of heat dissipation components 5. The top of the heat dissipation component 5 is provided with a toothed barrier 9. A groove bottom 6 is formed between two adjacent heat dissipation components 5 and the groove bottom 6. The part of the two heat dissipation components 5 near the toothed barrier 9 is provided as a widening groove 7. A narrowing opening 8 is formed between the toothed barriers 9. A plurality of arc-shaped grooves 10 are opened in the top recessed part of the toothed barrier 9.

[0019] When the medical ozone discharge tube is working, a high voltage is applied between the inner electrode 1 and the outer electrode 4. Under the isolation of the dielectric ceramic tube 3, a discharge electric field is formed. Oxygen undergoes an ionization reaction within the oxygen channel 2 to generate ozone. During this process, the outer electrode 4 continuously generates heat. Multiple heat sinks 5 on the outer wall of the outer electrode 4 rapidly conduct the heat to themselves. Simultaneously, the groove bottom 6 formed by two adjacent heat sinks 5 and the groove bottom 6, the widened groove 7 of the heat sink 5 near the toothed barrier 9, and the narrowed opening 8 between the toothed barriers 9 together constitute an airflow channel, allowing external air to enter naturally or be forced into the channel. Furthermore, the multiple arc-shaped grooves 10 on the recessed part of the top of the toothed barrier 9, as well as its own recessed inner toothed groove structure, further increase the contact area between the heat sink 5 and the air, allowing the air to more fully contact the heat sink 5 as it flows within the channel, carrying away the heat from the heat sink 5. This ultimately achieves continuous and efficient heat dissipation of the discharge tube, preventing excessively high tube temperatures from affecting ozone generation.

[0020] The multiple heat sinks 5 on the outer wall of the outer electrode 4 have already increased the heat dissipation contact area. Combined with the arc-shaped groove 10 at the top of the toothed barrier 9 and the recessed inner toothed groove structure, this further increases the heat exchange area between the heat sink 5 and the air, enabling faster transfer of heat generated by the outer electrode 4 into the air. Simultaneously, the flow channel formed by the groove bottom 6, the widened groove 7, and the narrowed opening 8 guides the orderly flow of air, allowing the air to more comprehensively cover the heat sink 5, reducing heat accumulation, ensuring the discharge cavity remains at a suitable operating temperature, preventing ozone decomposition due to high temperatures, and ensuring stable ozone generation efficiency and concentration.

[0021] See Figure 2-3A dielectric ceramic tube 3 is installed on the inner wall of the tank bottom 6. An oxygen channel 2 is provided on the side of the dielectric ceramic tube 3 away from the external electrode 4. An internal electrode 1 is provided on the side of the oxygen channel 2 away from the dielectric ceramic tube 3.

[0022] A dielectric ceramic tube 3 is installed on the inner wall of the tank bottom 6. The insulating properties of the dielectric ceramic tube 3 prevent direct contact between the inner electrode 1 and the outer electrode 4, thus avoiding a short circuit. This allows a stable high-voltage electric field to be formed between the inner electrode 1 and the outer electrode 4, ensuring the continuous oxygen ionization reaction. An oxygen channel 2 is located on the side of the dielectric ceramic tube 3 furthest from the outer electrode 4, between the inner electrode 1 and the dielectric ceramic tube 3. This location is precisely the core area of ​​the high-voltage electric field. Oxygen entering the oxygen channel 2 can directly contact the electric field, reducing the amount of oxygen remaining in non-field areas and allowing more oxygen to participate in ionization. The reaction is facilitated by the channel structure, which also guides the orderly flow of oxygen and avoids uneven oxygen distribution from affecting the reaction efficiency. The inner electrode 1 is set on the side of the oxygen channel 2 away from the dielectric ceramic tube 3, which allows the inner electrode 1 to be closer to the oxygen channel 2, further enhancing the effect of the electric field on the oxygen and ensuring that the oxygen is fully ionized to generate ozone. Moreover, the inner electrode 1, oxygen channel 2, and dielectric ceramic tube 3 are arranged sequentially from the inside to the outside at the relevant positions on the bottom 6 of the tank. The positions of each component are fixed and independent, so there is no need to disassemble the core structure of the discharge tube cavity during later inspection or replacement, which reduces the difficulty of maintenance and reduces the impact on other components.

[0023] See Figure 2-3 The material of the inner electrode 1 is set as titanium alloy and stainless steel.

[0024] The inner electrode 1 is made of titanium alloy stainless steel, which firstly ensures good conductivity, allowing a stable high-voltage electric field to be formed between the inner electrode 1 and the outer electrode 4, meeting the power requirements for the ionization of oxygen to generate ozone. Secondly, titanium alloy stainless steel has strong corrosion resistance, while ozone has strong oxidizing properties. During long-term use, it can prevent the inner electrode 1 from being corroded by ozone or small impurities that may be generated during the discharge process, thus extending the service life of the inner electrode 1. At the same time, this material also has good structural strength. During the operation of the discharge cavity, even if it is affected by slight vibration or temperature changes, it is not easy to deform and can always maintain a stable shape and position, ensuring that the relative position between it and the oxygen channel 2 and the dielectric ceramic tube 3 remains unchanged, maintaining the stability of the electric field, and ensuring the stability of ozone generation efficiency and concentration.

[0025] See Figure 2-3 The heat sink 5 is made of aluminum alloy.

[0026] The heat sink 5 is made of aluminum alloy. Firstly, aluminum alloy has excellent thermal conductivity, which can quickly conduct the heat generated by the external electrode 4 during discharge to its own surface and then dissipate it through contact with the air, avoiding excessively high internal temperature of the discharge tube that could affect ozone generation. Secondly, aluminum alloy is lightweight, so when installed on the outer wall of the external electrode 4, it will not significantly increase the overall weight of the discharge tube, facilitating the overall assembly and layout of the equipment. At the same time, aluminum alloy has good corrosion resistance, resisting moisture in the air or small amounts of corrosive substances that may be generated during discharge, reducing the occurrence of rust on the heat sink 5 and extending its service life. Moreover, aluminum alloy is relatively easy to process and can be easily made into the required shape, adapting to the toothed isolation 9, arc groove 10, and other structures on the heat sink 5, ensuring heat dissipation while reducing production and processing costs.

[0027] See Figure 1 One end of the dielectric ceramic tube 3 is provided with a first sealing plug 11, and the top of the first sealing plug 11 is provided with an ozone outlet tube 13.

[0028] A first sealing plug 11 is provided at one end of the dielectric ceramic tube 3, which can seal that end of the dielectric ceramic tube 3 to prevent oxygen leakage when it flows and participates in the reaction inside the dielectric ceramic tube 3, and also to prevent external impurities from entering the interior of the dielectric ceramic tube 3 and affecting the ozone purity. An ozone outlet pipe 13 is provided at the top of the first sealing plug 11, which allows the ozone generated inside the dielectric ceramic tube 3 to be directly discharged through the ozone outlet pipe 13, without the need to open an outlet on the dielectric ceramic tube 3, reducing damage to the structure of the dielectric ceramic tube 3. At the same time, the ozone outlet pipe 13 can guide the ozone to be discharged in an orderly manner, which is convenient for connection with subsequent ozone delivery pipelines or medical equipment, ensuring that the generated ozone can be stably supplied to the medical use process.

[0029] See Figure 1 The other end of the dielectric ceramic tube 3 is fixedly installed with a second sealing plug 12, and an oxygen inlet pipe is fixedly installed on the outer wall of the second sealing plug 12. The other end of the oxygen inlet pipe extends into the interior of the oxygen channel 2.

[0030] The other end of the dielectric ceramic tube 3 is fixed with a second sealing plug 12, which can cooperate with the first sealing plug 11 to seal both ends of the dielectric ceramic tube 3, preventing the leakage of oxygen participating in the reaction inside the tube, and also preventing external dust, water vapor and other impurities from entering the interior of the dielectric ceramic tube 3 and affecting the purity of ozone generation. The oxygen inlet pipe fixed to the outer wall of the second sealing plug 12 extends into the interior of the oxygen channel 2, which can directly and accurately deliver external oxygen into the oxygen channel 2 without the need for additional holes in the dielectric ceramic tube 3 or other components, reducing damage to the overall structure. At the same time, it can ensure that oxygen enters the reaction area stably, avoiding oxygen loss or uneven distribution during the delivery process, and ensuring the smooth progress of the subsequent ionization reaction.

[0031] See Figure 2-3The heat sink 5 is arranged in a ring and uniformly on the outer wall of the outer electrode 4.

[0032] The heat sink 5 is arranged in a ring and uniformly on the outer wall of the outer electrode 4. This allows the heat generated in each part of the outer electrode 4 to be conducted by the nearby heat sink 5 in a timely manner, avoiding excessive local temperature of the outer electrode 4 and ensuring uniform temperature of the outer electrode 4. At the same time, the uniform arrangement of the heat sink 5 allows for more sufficient contact between the surrounding air and the heat sink 5, preventing heat dissipation dead zones caused by uneven distribution of the heat sink 5, thus improving the overall heat dissipation efficiency. Moreover, this arrangement allows the heat sink 5 to provide more balanced support for the outer electrode 4, reducing the deformation of the outer electrode 4 due to uneven stress and ensuring long-term stable operation of the discharge cavity.

[0033] See Figure 5 The width of the bottom of the groove 6 is less than the width of the widening groove 7, and the width of the widening groove 7 is greater than the width of the toothed barrier 9.

[0034] The width of the bottom 6 is smaller than the width of the widening groove 7, allowing the widening groove 7 to form a more spacious space, facilitating airflow between the heat sinks 5, reducing airflow resistance, and allowing heat to be carried away more smoothly. The width of the widening groove 7 is greater than the width of the toothed barrier 9, which prevents the toothed barrier 9 from affecting airflow within the widening groove 7, while also guiding airflow to a certain extent, preventing uneven heat dissipation caused by disordered airflow. At the same time, this width setting allows for a more compact structure of the heat sink 5 while ensuring heat dissipation effect, without taking up too much internal space of the equipment, and also enhances the structural stability of the heat sink 5 itself, reducing the possibility of deformation after long-term use.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
