Description

Technical Field

[0001] The present application relates to the technical field of ozone treatment, and more particularly to a liquid storage tank for an ozone water generating device and an ozone water generating device. Background Art

[0002] Ozone, also known as superoxide, is a strong oxidant and can effectively sterilize. Therefore, ozone water containing ozone is widely used in fields such as environmental protection, medical and health, water treatment, pharmaceuticals, food preparation, and cosmetics preparation that require sterilization or disinfection.

[0003] However, the current generation of ozone water involves large-scale generating devices with complex structures, and the concentration of the generated ozone water is not high and the concentration value is unstable. Generating high-concentration ozone water requires numerous process flows. Moreover, the current large-scale devices have a low output of ozone water. In addition, the half-life of ozone water is extremely short, and the storage of the generated ozone water also faces problems.

[0004] However, it is desirable to provide an ozone water generation solution that can provide high-concentration and controllable large-flow ozone water with a relatively simple and compact structure.

[0005] The above description is only for understanding the relevant technology in this field and does not admit that it belongs to the prior art. Summary of the Invention

[0006] Therefore, an embodiment of the present invention provides a liquid storage tank for an ozone water generating device with a relatively simple and compact structure. The ozone water generating device using this liquid storage tank has the ability to provide large-flow, high-concentration, and controllable ozone water.

[0015] Wherein, the third surrounding baffle is located outside the first and second surrounding baffles, thereby defining a transition zone between the first and second surrounding baffles and the third surrounding baffle.

[0016] Wherein, one of the first and second surrounding baffles surrounds the other, thereby defining an ozone water mixing zone within the first and second baffles and defining a communication channel within the first and second baffles that communicates the ozone water mixing zone and the transition zone.

[0021] In an embodiment of the present invention, the liquid storage tank for the ozone water generating device further includes an exhaust gas treatment device for treating ozone escaping from the ozone water.

[0022] In an embodiment of the present invention, the liquid storage tank includes an exhaust gas discharge pipe connected to the exhaust gas treatment device, including a first opening at the top of the ozone water mixing zone and a second opening at the top of the raw water buffer zone.

[0024] In an embodiment of the present invention, the communication channel has an annular inlet adjacent to the ozone water mixing zone and an annular outlet adjacent to the transition zone.

[0025] In an embodiment of the present invention, the water inlet is arranged at the bottom of the liquid storage tank and outside the third surrounding baffle; the water outlet is arranged in the ozone water mixing zone and at the center of the bottom of the liquid storage tank.

[0026] In an embodiment of the present invention, the water outlet includes a first valve with controllable flow rate adjustment and a second valve for user operation to allow the superoxide water to flow out through the water outlet, wherein the opening degree of the first valve is controlled based on the concentration of the superoxide water and the circulation state, and the opening degree of the first valve restricts the maximum flow rate through the water outlet.

[0083] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the detailed implementation manners and the drawings. Herein, the illustrative implementation manners and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0084] In the descriptions of the "ground electrode" and the "high-voltage discharge device" and their plate-like components herein, the "surface" refers to the side of the extension surface of the plate, and can also be referred to as the "(plate) surface", which is not limited to a plane and may have different heights (such as depressions or protrusions) on the same "surface"; the "side edge" refers to the narrow side edge of the plate other than the top and bottom.

[0085] In this article, "first" and "second" do not reflect relative importance and order, but are only used to distinguish different elements or features.

[0086] In an embodiment of the present invention, an ozone generation device and its liquid storage tank are provided, which provide ozone water with large flow rate, high concentration and stable concentration in a relatively compact structure. In an embodiment of the present invention, on the one hand, when continuously supplying ozone, the pump provides continuous circulation of the ozone water. On the other hand, multiple liquid regions are provided in the liquid storage tank, which can realize the possibility of providing large-flow and controllable high-concentration ozone water with a simple structure. In particular, by means of the settings of the mixing zone, the communication channel and the transition zone, and the positive pressure relative to the raw water provided by the pump, ozone water with a very high concentration and highly controllable concentration accuracy can be realized with a very simple structure. Optionally, by means of the raw water in the raw water buffer zone, the pressure stability under the above-mentioned circulation can be ensured, promoting the effective mixing of ozone and water, and forming relatively more stable ozone water (liquid).

[0087] With reference to Figures 1 to 5 Fig. 1 shows an ozone water generation device 1 according to an embodiment of the present invention.

[0088] As Figures 1 to 5 shown in the embodiment, the ozone water generation device 1 may include an ozone generator 2, a liquid storage tank 10, a first communication pipe 18, a second communication pipe 16 and a pump 5. Optionally, the ozone water generation device 1 may further include a gas-liquid separator 6.

[0089] Continue to refer to Figures 1 to 5, the ozone generator 2 has a reaction gas inlet 21 for receiving reaction gas, an ozone outlet 22 for outputting ozone, a cooling fluid inlet 23 for cooling fluid inflow, and a cooling fluid outlet 24 for cooling fluid outflow. An exemplary ozone generator will be described below with reference to Figures 6 to 32 for description.

[0090] Continuing to refer to Figures 1 to 5 , the liquid storage tank 10 may include a tank body 11, a water inlet 11' for inputting raw water, a water outlet 16 for outputting superoxide water, a circulating liquid supply pipe 15 for supplying the superoxide water mixed with the raw water and the ozone, a circulating liquid outlet 18', a first surrounding baffle 12 extending from the bottom to near the top, a second surrounding baffle 13 extending from the top to near the bottom, and a third surrounding baffle 14 extending from the bottom to a certain height. In the embodiments of the present invention, the "near" can be clearly determined by those skilled in the art after reading the teachings of the present invention. If not clear, the "near" or "adjacent" means that the distance to the top or bottom is less than 10% of the height of the liquid storage tank, preferably 8%, more preferably 5%. In some embodiments, the "certain height" is in the range of 15% to 80% of the height of the liquid storage tank, preferably in the range of 20% to 80%, preferably in the range of 20% to 70%, more preferably in the range of 20% to 60%, and more preferably in the range of 20% to 50%.

[0091] In the illustrated embodiment, the third surrounding baffle 14 is located on the outside, that is, outside the first and second surrounding baffles 12 and 13. In the illustrated embodiment, the first surrounding baffle 12 is located on the inside, and the second surrounding baffle 13 surrounds the first surrounding baffle 12. Thus, a superoxide water mixing zone 12' can be defined within the first and second baffles 12 and 13, a communication channel 13' can be defined between the first and second surrounding baffles 12 and 13, a transition zone 14' can be defined between the first and second surrounding baffles 12 and 13 and the third surrounding baffle 14, and the communication channel 13' communicates the superoxide water mixing zone 12' and the transition zone 14'. Further, a raw water buffer zone 14" is defined outside the third surrounding baffle 14 (between it and the tank body 11). In the embodiments of the present invention, the regions are generally divided according to the structure of the surrounding baffles (and their relationship with the tank body), but no precise boundaries are provided. Under the teachings of the present invention, those skilled in the art know how to implement the present invention, including setting the baffles and defining the corresponding regions.

[0092] As Figures 1 to 5In the illustrated embodiment, the communication channel 13' has an inlet (not labeled), such as an annular inlet, near the top, and an outlet (not labeled), such as an annular outlet, near the bottom. The inlet and the outlet, such as the annular inlet and the annular outlet, can be defined, for example, jointly by corresponding portions of the first and second surrounding baffles near the top or the bottom of the liquid storage tank. In the illustrated embodiment, the annular inlet of the communication channel is near the superoxide water mixing zone, and the annular outlet is near the transition zone.

[0093] such as Figures 1 to 5 In the illustrated embodiment, the circulating liquid supply pipe 15 extends into the superoxide water mixing zone 12'. As shown in the figure, the circulating liquid supply pipe 15 has end openings 15', as shown, a plurality of which are circumferentially symmetrically arranged around the end of the circulating liquid supply pipe 15. such as Figures 1 to 5 In the illustrated embodiment, the end openings 15' are arranged away from the annular inlet, and here they are arranged near the bottom.

[0094] In such as Figures 1 to 5 In the illustrated embodiment, the second surrounding baffle 13 surrounds the first surrounding baffle 12, but a reverse structure can be envisioned, that is, the first surrounding baffle surrounds the second surrounding baffle. In this embodiment, the inlet and outlet of the communication channel, as well as the circulating liquid supply pipe and its end openings, can be set accordingly according to the teachings of the present invention.

[0095] In such as Figures 1 to 5 In the illustrated embodiment, the cross-sections of the first, second, and third surrounding baffles 12, 13, 14 are substantially circular and are coaxially arranged. As shown in the figure, the cross-section of the liquid storage tank or the tank body 11 is also substantially circular and is coaxially arranged with the first, second, and third surrounding baffles 12, 13, 14. Here, the superoxide water mixing zone can have a circular cross-section, and the communication channel and the transition zone can have an annular cross-section.

[0096] In such as Figures 1 to 5 In the illustrated embodiment, further, the water inlet 11' is arranged in the raw water buffer zone 14". such as Figure 1 Best shown, the water inlet 11' is arranged at the bottom of the liquid storage tank body 11 and is located outside the third surrounding baffle 14.

[0097] In such as Figures 1 to 5In the illustrated embodiment, further, the water outlet 16 is provided in the ozone water mixing zone 12", preferably adjacent to the end opening 15' of the circulating liquid supply pipe 15. In the illustrated preferred embodiment, the water outlet 16 is provided at the center of the bottom of the liquid storage tank body 11. In an embodiment of the present invention, the water outlet 16 may include a first, controllable flow regulating valve (not shown) and a second, operating valve (not shown). In some embodiments of the present invention, the concentration controller may control the opening degree of the first valve according to different ozone water concentrations and circulating states, as described below. The user can operate the second valve to allow the ozone water to flow out through the water outlet. Specifically, the user can operate the opening degree of the second valve according to the desired ozone water flow rate. Additionally, the first valve restricts the maximum flow rate that can flow out through this water outlet, and the user can operate the second valve as needed to allow the ozone water flow rate flowing out through the water outlet to be controlled within a range less than or equal to this maximum flow rate.

[0098] As Figure 2 Best shown, the circulating liquid outlet 18' is provided in the transition zone 14'. In the illustrated preferred embodiment, the circulating liquid outlet 18' is provided at the bottom of the liquid storage tank body 11, within the annular region of the transition zone 14'.

[0099] As Figures 1 to 5 Shown, the circulating liquid outlet 18' is connected to the first connecting pipe 18, and one end of the circulating liquid supply pipe 15 remote from the end opening is connected to the second connecting pipe 16.

[0100] Continuing to refer Figures 1 to 5 , the ozone water generating device 1, specifically the liquid storage tank 10, may further include an exhaust gas treatment device 17 for treating the ozone escaping from the ozone water. Further, the liquid storage tank may include an exhaust gas discharge pipe 170 connected to the exhaust gas treatment device 17, which may generally be in a U shape. As Figure 1 And Figure 3 Shown, the exhaust gas discharge pipe 170 may include a first opening 171 at the top of the ozone water mixing zone and a second opening 172 at the top of the tank body and outside the first and second surrounding baffles. In some embodiments, the exhaust gas treatment device 17 may contain an ozone destroying agent, such as an ozone destroying catalyst. In some embodiments, a gas-liquid separation element (not shown) may be provided in the exhaust gas discharge pipe 170.

[0101] Continuing to refer Figures 1 to 5, the superoxide water generating device 1, specifically the liquid storage tank 10, may further include a liquid level controller 19 located outside the first and second surrounding baffles. The liquid level controller 19 is configured to allow the pump to pump in response to detecting that the liquid level reaches the low liquid level 101 (i.e., greater than or equal to), and to stop the input of the raw water through the water inlet in response to detecting that the liquid level reaches the high liquid level 102. In some embodiments, when the liquid level is lower than the low liquid level, pumping may be stopped, and optionally the water inlet may be automatically opened to allow the supply of raw water. In the embodiments of the present invention, the low liquid level can be set as needed, for example, at the 20% height position, 30% height position, 40% height position, 50% height position of the liquid storage tank 10; the high liquid level can be set as needed, for example, at the 60% height position, 70% height position, 80% height position, 90% height position of the liquid storage tank 10.

[0102] As Figures 1 to 5 shown, the pump 5 is connected between the first connecting pipe 18 and the second connecting pipe 16, more specifically connected to the first connecting pipe 18, and the ozone flow outlet 22 of the ozone generator 2 is at the position of the pump 5, as shown in the figure as the docking part of the pump and the first connecting pipe, and is connected into the circulation loop as described below.

[0103] As Figures 1 to 5 shown, the gas-liquid separator 6 is arranged between the pump 5 and the second connecting pipe 16. More specifically, the gas-liquid separator 6 includes a fluid inlet 61 connecting the pump 5, a first liquid outlet 62 connecting the second connecting pipe 16, and a second gas outlet 63 for separating out the tail gas. The second gas outlet 63 can be connected to the tail gas treatment device 17.

[0104] Thus, the pump 5 is configured to pump the raw water, the ozone, and the mixed superoxide water through a cycle that passes through the liquid storage tank 10, the second connecting pipe 18, optionally the gas-liquid separator 6, the first connecting pipe 16, and returns to the liquid storage tank. In a specific embodiment of the present invention, the cycle passes through the superoxide water mixing area 12' of the liquid storage tank, the communication channel 13', optionally the transition area 14', the first connecting pipe 18, optionally the gas-liquid separator 6, the second connecting pipe 16, the circulating liquid supply pipe 15, and then enters the superoxide water mixing area 12' of the liquid storage tank 10.

[0105] Although not shown in the figures, the superoxide water generating device 1 may further include a concentration controller for controlling the concentration of superoxide water in the liquid storage tank 10, more specifically, the superoxide water mixing zone 12' of the liquid storage tank 10, whereby the concentration of the superoxide water discharged from the water outlet 16 can be controlled. In a preferred embodiment of the present invention, the concentration controller may be configured to control the concentration of the superoxide water by controlling the number of cycles of the superoxide water. For example, in one embodiment, the number of cycles of the superoxide water can be correspondingly controlled according to the superoxide water concentration set by the user. In the embodiment of the present invention, the number of cycles can be determined in various ways, such as determined based on the pumping flow rate and ozone concentration (and can be multiplied by a weighting factor), or can be determined according to the pumping / ozone concentration-superoxide water concentration curve or look-up table based on the cycle (flow rate). By means of circulating a predetermined number of cycles, superoxide water with a high concentration and highly controllable concentration can be achieved by a very simple means, and the generated superoxide water has a better mixing effect and a longer half-life due to the impact between multiple components.

[0106] In addition, by providing a plurality of surrounding baffles in the liquid storage tank 10 and thereby defining a plurality of regions, while maintaining a large amount of raw water in the buffer (cache) zone of the raw water in the tank, for example, the specific structures of the mixing zone, the communication channel, and the transition zone allow the superoxide water participating in the cycle to continuously add ozone to increase the concentration of the superoxide water, and the positive pressure applied from the communication channel to the transition zone ensures the concentration of the liquid participating in the cycle. Thus, superoxide water can be provided in a large flow rate and a controlled high concentration.

[0107] Optionally, the circulation and the optional supply of ozone can be stopped after reaching the corresponding number of cycles.

[0108] In a preferred embodiment of the present invention, the concentration controller may be configured to control the pump to pump at a first pumping pressure within a predetermined number of cycles in response to the set superoxide water concentration.

[0109] In some embodiments of the present invention, the pumping can be stopped when the predetermined number of cycles is reached.

[0110] However, in another preferred embodiment, after reaching a predetermined number of cycles, the pump is controlled to pump at a second pumping pressure. Specifically, after the user sets a predetermined concentration of superoxide water, for example, the pump circulates a predetermined number of times at the optimal power (first pumping pressure) of the pump and / or at (e.g., maximum) the first ozone supply flow rate as described above. After reaching the predetermined number of cycles, the pump circulates at a pump power (second pumping pressure) and / or a second ozone supply flow rate different from the foregoing (e.g., called a maintenance cycle). The latter cycle can be used to maintain the set concentration of superoxide water in the main superoxide water tank. In some embodiments, the different pump powers (pumping pressures) can be such that the second pumping pressure curve is different from the first pumping pressure curve and / or the second pumping pressure is less than the first pumping pressure. For example, when the pump is a constant pressure or constant power pump, the first pumping pressure curve can be a horizontal line of continuous operation, and the second pumping pressure curve is a substantially intermittent pressure curve, that is, after reaching the predetermined cycle, the pump pumps intermittently to substantially maintain the concentration of superoxide water. It can also be envisioned that the second pumping pressure curve can also be a horizontal line of continuous operation, but the pumping pressure (power) is lower than the first pumping pressure (power); or, it can be envisioned that the second pumping pressure is a combination of the two, for example, the second pumping pressure curve is pulsating.

[0111] In a preferred embodiment of the present invention, the concentration controller can be configured to control the ozone outlet to output the ozone at a first ozone concentration within a predetermined number of cycles in response to the set concentration of superoxide water. In some preferred embodiments, the first ozone concentration can be the maximum ozone concentration that the ozone generator can supply.

[0112] In some embodiments of the present invention, after reaching a predetermined number of cycles, the output (supply) of ozone can be stopped.

[0113] However, in another preferred embodiment, after reaching a predetermined number of cycles, such as in a maintenance cycle, the ozone outlet can be controlled to output the ozone at a second ozone concentration. Similarly, the second ozone concentration can be lower than the first ozone concentration. Or the ozone concentration supplied after reaching the predetermined number of cycles can vary pulsatingly or intermittently. Such a configuration allows the concentration control accuracy of the superoxide water generating device of the embodiments of the present invention to be maintained at an extremely high level and still ensure a relatively large flow rate of superoxide water supply.

[0114] In some embodiments, when the concentration in the superoxide water mixing zone 12' reaches the set concentration, such as when a predetermined cycle is reached, it can be notified or indicated in various ways that the superoxide water has reached the set concentration and can be used. At this time, the second valve of the aforementioned water outlet can be operated to use the superoxide water. In the embodiments of the present invention, the first valve of the water outlet can be automatically opened when the predetermined cycle is reached, or opened in response to the opening of the second valve. In the embodiments of the present invention, the concentration controller can be configured to dynamically adjust the pumping pressure (power) of the pump and / or the ozone concentration according to the set concentration and dynamically control the opening degree of the second valve to maintain the concentration of the superoxide water in the superoxide water mixing zone at the set concentration. This can be determined, for example, according to the aforementioned pumping / ozone concentration - superoxide water concentration curve based on the cycle (flow rate) or by looking up a table (taking into account the flow rate loss caused by the opening degree of the second valve). Such a setting can particularly advantageously stabilize the high-concentration superoxide water. In this embodiment, for example, the third pumping pressure and / or the third concentration can be set as needed.

[0115] For example, in some embodiments of the present invention, the first stage, the second stage, and the third stage can be set correspondingly. For example, the first stage is the stage where the set concentration has not been reached (the predetermined cycle has not been reached); the second stage is the stage where the set concentration has been reached and the superoxide water has not been used; the third stage is the stage where the set concentration has been reached, but the superoxide water is being used. In the embodiments of the present invention, the definitions of these three stages can enable the superoxide water generating device according to the embodiments of the present invention to provide superoxide water with a large flow rate and highly controllable high concentration, and these three stages can transition smoothly. For example, when the continuous use of the superoxide water causes the concentration of the superoxide water to be discharged to be lower than the set concentration, the concentration controller may control the opening degree of the second valve to gradually decrease until it is closed to maintain the concentration in the superoxide water mixing zone 12'.

[0116] Continuing to refer to Figures 1 to 5 , the superoxide water generating device 1 may further include a reaction gas generator 3, such as an oxygen generator, which is connected to the reaction gas inlet 21 of the ozone generator. Continuing to refer to Figures 1 to 5 , the superoxide water generating device 1 may further include a cooling fluid generator 7, which may include an outlet 71 connected to the cooling fluid inlet 23 of the ozone generator 2 and an inlet 72 connected to the cooling fluid outlet 24 of the ozone generator.

[0117] Continuing to refer to Figures 1 to 5 , the superoxide water generating device 1 may further include an electrical control system (not labeled), and the aforementioned concentration controller may or may not be integrated in this electrical control system.

[0118] Continuing to refer to Figures 1 to 5 , the superoxide water generating device 1 may further include a frame 4 for supporting each component of the superoxide water generating device.

[0119] In multiple embodiments of the present invention, there is provided an ozone generator 2, in particular an ozone generator based on a plate-type ozone generation module and related ozone generator components, which can be used in the ozone water generation device 1 according to the embodiments of the present invention. The plate-type ozone generation module of the ozone generator may include a plurality of stacked plate-shaped ground electrodes and at least one high-voltage discharge device located between adjacent ground electrodes.

[0120] In some embodiments of the present invention, the ozone generator, in particular the ozone generator based on the plate-type ozone generation module, can be applied to a portable small chassis scenario, where the plate-type ozone generation module is, for example, optionally non-expandable.

[0121] The following refers to the embodiments shown in the accompanying drawings.

[0122] In some embodiments of the present invention, the ozone generator, in particular the ozone generator based on the plate-type ozone generation module, can be applied to a portable small chassis scenario (such as a 100g output product), where the plate-type ozone generation module is, for example, non-expandable. The ozone generator can be used in the ozone water generation device according to the embodiments of the present invention.

[0123] Reference Figures 6 to 10 , shows an ozone generation device according to an embodiment of the present invention, such as a chassis-type ozone generator 2, which can be used in the ozone water generation device according to the embodiments of the present invention. The chassis-type ozone generator 2 may include a box body, a plate-type ozone generation module 20, and a heating electrical component 26. In the shown embodiment, the plate-type ozone generation module 20 may include a pair of ground electrodes (such as a pair of end ground electrodes), a high-voltage discharge device (not shown) disposed between the ground electrodes, and a high-voltage fuse device (not shown) electrically connected to the high-voltage discharge device, and the electrical connection is realized, for example, through a plug connector. In some embodiments, the pair of ground electrodes (such as a pair of end ground electrodes) is, for example, in Figures 11 to 18 or Figures 19 to 26 as shown. In some embodiments, the high-voltage discharge device is, for example, in Figures 27 to 28 as shown. In some embodiments, the high-voltage fuse device 23 is, for example, in Figures 29 to 32 as shown.

[0124] In the shown embodiment, the box body includes a front panel 251, a rear panel 252, a bottom plate, a top plate (the top plate is removed to show the internal structure), and a pair of side plates (one of the side plates is removed to show the internal structure). In the shown embodiment, the bottom plate includes a pair of flanges 254. In the shown embodiment, the box body may further include a pair of top longitudinal beams 253. In the shown embodiment, the bottom plate and its flanges form a bottom groove 255 at the bottom of the box body. Similarly, the top plate and the longitudinal beams 53 form a top groove 257 at the top of the box body.

[0125] Continue to refer to Figures 6 to 10 , the chassis-type ozone generator 2 may further include a partition 250 vertically installed in the cabinet, whereby the partition divides a gas generation chamber at the rear side and an electrical chamber at the front side in the cabinet. The plate-type ozone generation module 20 is located in the gas generation chamber, and a plurality of heating electrical components are arranged in the electrical chamber.

[0126] In the illustrated embodiment, the partition at least partially defines a bottom opening 258 and a top opening 259. As Figure 6 shown, the bottom plate and its folded edge 254 and the partition 250 together form the bottom opening 258. More specifically, with the partition 250 supported by the folded edge 254, the bottom opening 258 is formed in the bottom groove 255 formed in the bottom plate. As Figure 6 shown, the longitudinal beam 253 can space the top plate from the partition 250 to form the top opening 259. More specifically, with the partition 250 supporting the longitudinal beam 253, the top opening 259 is formed in the top groove 257.

[0127] Combined with Figures 6 to 10 shown, the top opening 259 is a long and narrow opening. In the illustrated embodiment, the top opening 259 has a width greater than that of the bottom opening 258 and an area smaller than that of the bottom opening. In these embodiments, reducing the height and area of the top opening seemingly does not contribute to forming a good circulating cooling air flow, but the inventors found that this can achieve a balance of higher and more stable circulating air flow and improve the cooling effect, while also ensuring safety and moisture isolation effects.

[0128] In the illustrated embodiment, a forced air supply device 290, such as a blower, may also be provided at the bottom opening 258 for forming a circulating cooling air flow that circulates through the top opening and the bottom opening in the gas generation chamber and the electrical chamber, especially for forming a circulating cooling air flow that flows from the gas generation chamber into the electrical chamber through the bottom opening and flows from the electrical chamber into the gas generation chamber through the top opening. As Figure 6 shown, the bottom opening 258 is completely covered by the forced air supply device 290, which can obtain higher cooling fluid stability.

[0129] Accordingly, the chassis-type ozone generator of the embodiments of the present invention not only has an extremely compact structure to achieve portability, but also realizes high safety by substantially separating the gas reaction components and the electrical components, and can also reduce or avoid the condensation of the gas reaction components and reduce or avoid the influence of moisture on the electrical components. Further, by means of the top and bottom openings in the embodiments of the present invention, and further by means of the forced air supply device, the cooling of the heating electrical components can be effectively achieved. In particular, the forced air supply device according to the embodiments of the present invention, such as a fan, is not arranged in an intuitive manner to directly blow the heating element, but together with the top and bottom openings, it creates the circulating cooling air flow, instead achieving a higher cooling effect, and the cooling effect is more continuous and stable. This may contribute to the ozone generator being able to stably maintain a high ozone generation efficiency for a long time.

[0130] Continue to refer to Figures 6 to 10 , the chassis-type ozone generator 2 may further include at least one (for example, a pair) of top hanging plates 291 and at least one bottom support leg 292 for hanging and supporting the plate-type ozone generation module in the gas generation chamber to form a clearance for avoiding the top opening and the bottom opening. In this embodiment, the clearance of the plate-type ozone generation module, especially the ground electrode, avoiding the top opening 259 / bottom opening 258 may seem to have lower heat exchange efficiency than when the top and bottom openings directly face the plate-type ozone generation module, especially the ground electrode (plate-like structure). However, the inventor found that the clearance (formed by means of the bottom groove 255 and the top groove 257, for example) can provide improved cooling efficiency. This is not necessarily an explanation of the principle (nor should it be a limitation). Perhaps it is because the clearance in the embodiment improves the circulation efficiency of the circulating air flow, thereby obtaining an improved heat exchange effect.

[0131] Continue to refer to Figures 6 to 10 , the electrical components 26 may include a drive variable-frequency power supply 261, a conversion transformer 262 electrically connected to the drive variable-frequency power supply 261, and a resonant high-voltage coil 263 electrically connected to the conversion transformer 262. In some embodiments, the current output by the drive variable-frequency power supply 261 can be boosted in two stages through the conversion transformer 262 and the resonant high-voltage coil 263 to achieve the high voltage required by the plate-type ozone generation module 20. In the shown embodiment, the drive variable-frequency power supply 261 is vertically arranged between the conversion transformer 262 and the resonant high-voltage coil 263.

[0132] Continue to refer to Figures 6 to 10, the electrical component 26 may further include a filter unit 266 connected to the drive variable-frequency power supply, a control power supply 265 connected to the filter unit 266, and a control and display unit 264 connected to the control power supply 265. By providing a filter unit in the electrical connection line, the control power supply can be obtained from the drive power supply and still operate properly, avoiding the need for the control power supply to be provided by a separate line or for additional voltage transformation and rectification devices to be provided for the control power supply. In the illustrated embodiment, the control and display unit 264 is disposed vertically adjacent to the drive variable-frequency unit 261 and away from the resonant high-voltage coil. With this structure, the influence of the resonant high-voltage coil on the control unit is minimized.

[0133] Continuing to refer Figures 6 to 10 , the ozone generator 2 may further include a cooling fluid inlet fitting 281, a cooling fluid outlet fitting 282, an air inlet fitting 283, and an air outlet fitting 284 for the plate-type ozone generation module 20 of the ozone generator 2. The fittings can be used to Figures 11 to 18 and / or Figures 19 to 26 supply or receive cooling fluid or supply or receive gas to or from the ground electrode.

[0134] Continuing to refer Figures 6 to 10 , the ozone generator 2 may further include a flowmeter fitting 288 for detecting and controlling the flow rate of the plate-type ozone generation module 20.

[0135] Continuing to refer Figures 6 to 10 , the ozone generator 2 may further include a power supply terminal 296 located in the rear panel 252, which can be electrically connected to the drive variable-frequency power supply 261, for example. In the illustrated embodiment, the electrical connection lines are not shown but can be provided as needed, for example, by passing through the partition from the gas generation chamber to the electrical chamber.

[0136] As previously described, the plate-type ozone generation module 20 may include a stacked ground electrode and a high-voltage discharge device disposed between the ground electrodes.

[0137] Refer Figures 11 to 18 , a plurality of embodiments of the ground electrode according to embodiments of the present invention are described.

[0138] As Figures 11 to 14A ground electrode 221 according to an embodiment of the present invention is shown. The ground electrode 221 includes a plate body having a first surface 200, a second surface 202, a first side and a second side, and a cooling fluid channel 2211 formed inside the plate body. The cooling fluid channel 2211 may include a borehole formed inside the plate body and a connecting groove 22114 connecting adjacent boreholes, so that, for example, a single-loop tortuous cooling fluid circuit can be formed in the ground electrode 221. Optionally, a cooling fluid channel connected to an adjacent ground electrode can be formed, for example, by means of the connecting groove 2114. Optionally, the borehole can be selectively closed or opened, so as to form a bottom (or top) inlet and outlet for the cooling fluid to flow into or out of the ground electrode. The specific structure and function of the cooling fluid channel are not repeated here.

[0139] Continue to refer Figures 11 to 14 In the embodiment shown, the plate body has a contact surface 2210 for close contact with the high-voltage discharge device in at least one of the first surface and the second surface (the first surface 200 in the embodiment shown) and a plurality of transversely juxtaposed micro-air channels 2212 formed by being recessed from the contact surface 2210. In the embodiment shown, the contact surface 2210 and the micro-air channels 2212 can be formed in a surface depression of the plate body, for example. In the embodiment shown, the ground electrode 221 can also include a first longitudinal air groove 2213 located at the first side edge and a second longitudinal air groove 2214 located at the second side edge. In the embodiment shown, the first longitudinal air groove 2213 and the second longitudinal air groove 2214 are sink grooves.

[0140] Continue to refer Figures 11 to 14 Each micro air channel 2212 may extend from the first longitudinal air groove 2213 to the second longitudinal air groove 2214 and have a narrowing portion 22120 adjacent to the second longitudinal air groove 2214 .

[0141] Therefore, the ground electrode of the embodiment of the present invention has a highly integrated plate-like structure. In addition, compared with the intuitive concept of increasing the flow area of ​​the microchannel as much as possible to increase the gas production rate and ensuring the uniform distribution of the channels as much as possible to ensure uniform airflow to increase the gas production rate, it is surprisingly found that the embodiment of the present invention is provided with a narrowing portion that partially reduces the flow area of ​​the microchannel and seems to cause an unstable airflow to obtain a more efficient ozone production efficiency.

[0142] like Figures 11 to 14 As shown, the narrowing portion includes a necking section, preferably an arc-shaped necking section with symmetrical arc-shaped edges. Optionally, the necking ratio of the necking section is between 1:2.5 and 1:15, preferably between 1:5 and 1:10. Setting a significantly narrowed necking ratio can provide a more efficient ozone production efficiency. Optionally, the ratio of the length of the necking section to the length of the micro-airway is between 1:5 and 1:20.

[0143] As shown Figures 11 to 14 in the figure, the constriction portion further includes a small-diameter section 22122 connecting the necking section and the second longitudinal air groove. Preferably, the small-diameter section is a straight section or a slightly expanding section. The length of the small-diameter section is significantly smaller than the length of the necking section. For example, the ratio of the length of the small-diameter section to the length of the necking section is less than 1:10. Surprisingly, setting the small-diameter section with a smaller length can be beneficial to further improve the ozone production efficiency. By way of explanation and not limitation, it is speculated that the small-diameter section can be beneficial to the rapid discharge of the generated ozone, while the necking section allows the reaction oxygen to fully react through discharge to generate ozone.

[0144] In the embodiment as Figures 11 to 14 shown, the ground electrode 221 is a first-end ground electrode, such as a start-end ground electrode. The plate body of the first-end ground electrode 221 has only the contact surface 2210 and the micro air duct 2212 on the first surface 200, and the second surface of the plate body forms an end face.

[0145] As Figure 14 shown, the plate body of the first-end ground electrode 221 further includes an air inlet hole 2215 located on the first side and extending from the second surface 2202 towards the first surface 200, and an air outlet hole 2216 located on the second side and extending from the second surface 2202 towards the first surface 200. In the shown embodiment, the air inlet hole 2215 is offset from the first longitudinal air groove 2213, that is, in the planar projection, the air inlet hole 2215 is located outside the first longitudinal air groove 2213. In the shown embodiment, the air outlet hole 2216 is offset from the second longitudinal air groove 2214. As Figure 13 shown, the plate body of the first-end ground electrode 221 further includes at least one (such as a pair) of first long holes 2217 for communicating the air inlet hole 2215 and the first longitudinal air groove 2213, and at least one (such as a pair) of second long holes 2218 for communicating the second longitudinal air groove 2214 and the air outlet hole 2216. In the shown embodiment, the pair of first long holes 2217 is symmetrically arranged with respect to the transverse center axis of the ground electrode; the pair of second long holes 2218 is symmetrically arranged with respect to the transverse center axis of the ground electrode. As Figure 12 best shown, the first long holes are parallel and offset from the first longitudinal air groove. In the shown embodiment, the first longitudinal air groove 2213 is located at a first height on the first surface 200, and the first long holes 2217 are located at a second height higher than the first height on the first surface 200. As Figure 12Best shown, the second long hole 2218 is disposed parallel and offset to the second longitudinal air groove 2214. The second longitudinal air groove 2214 is located at a third height in the first surface 200 (e.g., at the same height as the first longitudinal air groove), and the second long hole 2218 is located at a fourth height higher than the third height in the first surface 200 (e.g., at the same height as the first long hole).

[0146] As Figure 12 shown, the plate body may further include a drilled hole for communicating the long hole and the inlet / outlet air hole, which may be parallel to the longitudinal air groove.

[0147] Continuing to refer to Figures 15 to 18 , the ground electrode 222 according to another embodiment of the present invention is shown. The ground electrode 222 includes a plate body having a first surface 200, a second surface 202, a first side edge, and a second side edge, and a cooling fluid channel formed inside the plate body.

[0148] Continuing to refer to Figures 15 to 18 , in the illustrated embodiment, the plate body has a contact surface for closely adhering to the high-voltage discharge device in at least one of the first surface and the second surface (in the illustrated embodiment, it is the first surface 202), and a plurality of laterally juxtaposed micro air channels 2222 formed by recessing from the contact surface. In the embodiment, the contact surface and the micro air channels 2222 may be formed, for example, in the surface recessed area of the plate body. In the illustrated embodiment, the ground electrode 222 may further include a first longitudinal air groove 2223 located at the first side edge and a second longitudinal air groove 2224 located at the second side edge. In the illustrated embodiment, the first longitudinal air groove 2223 and the second longitudinal air groove 2224 are sunk grooves.

[0149] Continuing to refer to Figures 15 to 18 , each micro air channel extends from the first longitudinal air groove to the second longitudinal air groove and has a narrowing portion 22220 adjacent to the second longitudinal air groove.

[0150] In the embodiment as Figures 15 to 18 shown, the ground electrode 222 is a second end ground electrode, for example, a terminal ground electrode, and its plate body has only the contact surface and the micro air channels on the second surface 2202, and the first surface of the plate body constitutes an end surface.

[0151] The ground electrode 222 has similar contact surfaces, micro air channels, and longitudinal air grooves, and the main difference from the ground electrode 221 is that the contact surface, the micro air channels, and the longitudinal air grooves of the ground electrode 222 are formed in the second surface 2202. Optionally, the surface recessed area of the ground electrode 222 is deeper. Compared with the ground electrode 221, the ground electrode 222 does not have an air inlet hole and an air outlet hole.

[0152] In the illustrated embodiment, the ground electrode 222 may further include a receiving groove 2229 in the second surface for receiving the connector head of the high-voltage discharge device.

[0153] Although not shown in the drawings, in some embodiments, a ground electrode pair for an ozone generator is provided, which includes stacked end ground electrodes such as Figures 11 to 18 the pair of end ground electrodes of the illustrated embodiment. In these embodiments, the first longitudinal gas grooves of the pair of end ground electrodes communicate with each other in the stacking direction, and the second longitudinal gas grooves of the pair of end ground electrodes communicate with each other in the stacking direction.

[0154] In a preferred embodiment, in the projection on a plane, the first longitudinal groove and the offset first elongated hole of the first end ground electrode are located within the envelope of the first longitudinal groove of the second end ground electrode, and the second longitudinal groove and the offset second elongated hole of the first end ground electrode are located within the envelope of the second longitudinal groove of the second end ground electrode. This can improve the gas production efficiency.

[0155] Although not shown in the drawings, in some embodiments, a plate-type ozone generation module is provided, which includes the stacked ground electrode pair described above and a plurality of high-voltage discharge devices located between adjacent ground electrodes. In a preferred embodiment, in the projection on a plane, the first longitudinal groove and the offset first elongated hole of the first end ground electrode are located within the envelope of the first longitudinal groove of the second end ground electrode, and the second longitudinal groove and the offset second elongated hole of the first end ground electrode are located within the envelope of the second longitudinal groove of the second end ground electrode. This can improve the gas production efficiency. In a further preferred embodiment, in the projection on a plane, the first elongated hole and the second elongated hole of the first end ground electrode are located outside the envelope of the high-voltage discharge device. This can greatly improve the gas production efficiency.

[0156] In an embodiment of the present invention, the intake pipe connector 283 can serve as Figures 1 to 5 the reaction gas inlet 21 of the illustrated embodiment, and the outlet pipe connector 284 can serve as Figures 1 to 5 the ozone outlet 22 shown in 2 of the illustrated embodiment. In an embodiment of the present invention, the cooling fluid inlet pipe connector 281 can serve as Figures 1 to 5 the cooling fluid inlet 23 of the illustrated embodiment, and the cooling fluid outlet pipe connector 282 can serve as Figures 1 to 5 the cooling fluid outlet 24 of the illustrated embodiment.

[0157] Although not shown in the drawings, in some embodiments, a plate-type ozone generation module is provided, which includes the stacked ground electrode pair described above and a high-voltage discharge device located between adjacent ground electrodes.

[0158] Reference Figures 19 to 26 describes multiple embodiments of the ground electrode according to the embodiments of the present invention.

[0159] like Figures 19 to 22 A ground electrode 224 according to an embodiment of the present invention is shown. The ground electrode 224 comprises a plate body having a first surface, a second surface, a first side edge and a second side edge, and a cooling fluid channel formed inside the plate body.

[0160] like Figures 19 to 22 In the illustrated embodiment, the plate body has a contact surface 2240 for close contact with the high-voltage discharge device in at least one of the first surface and the second surface (here the first surface), and at least one (here one) micro-air channel 2242 formed by being recessed from the contact surface.

[0161] The ground electrode 224 may further include a first longitudinal air groove 2243 located at the first side and a second longitudinal air groove 2244 located at the second side. In the illustrated embodiment, the first longitudinal air groove 2243 and the second longitudinal air groove 2244 are sink grooves.

[0162] like Figures 19 to 22 In the illustrated embodiment, the micro air channel 2242 extends from the first longitudinal air groove 2243 to the second longitudinal air groove 2244 in a zigzag manner. Thus, the ground electrode of the embodiment of the present invention has a highly integrated plate-like structure. In addition, compared with the intuitive concept of increasing the flow area of ​​the micro channel as much as possible to increase the gas production rate and ensuring that the straight channels are arranged in parallel and evenly as much as possible to ensure uniform airflow to increase the gas production rate, it is surprisingly found that the zigzag micro air channel of the embodiment of the present invention seems to cause the micro channel and its flow area to be unevenly distributed to obtain a more efficient ozone production efficiency.

[0163] like Figures 19 to 22 In the illustrated embodiment, the micro air channel 2242 may include an inflow section 22420 adjacent to the first longitudinal air groove, an outflow section 22421 adjacent to the second longitudinal air groove, and an intermediate tortuous section 22424 between the inflow section and the outflow section.

[0164] like Figures 19 to 22 In the embodiment shown, the intermediate tortuous section 22424 has a flared portion 22427, such as an arc-shaped flared portion, adjacent to the inflow section and / or a narrowed portion 22428, such as an arc-shaped narrowed portion, adjacent to the outflow section. Surprisingly, it has been found that the ozone production efficiency can be effectively improved by means of a flared portion connected to a narrower inflow section and a narrowed portion connected to a narrower outflow section.

[0165] like Figures 19 to 22 In the embodiment shown, the inflow section 22420 is rotationally symmetrical with the outflow section 22421. In addition, the intermediate zigzag section 22424 has a rotationally symmetrical shape relative to itself. Figures 19 to 22In the illustrated embodiment, the centers of rotation of the inflow section and the outflow section coincide with the center of rotation of the intermediate meandering section. The rotationally symmetric structure of the meandering micro-air channel can further improve the ozone production efficiency.

[0166] As Figures 19 to 22 In the illustrated embodiment, the intermediate meandering section 22424 includes a plurality of longitudinal straight sections (here 3) and at least one transverse curved arc section (here two) connecting adjacent longitudinal straight sections. The illustrated intermediate meandering section 22424 is generally in the shape of a fallen S. As shown in the figure, the oncoming flow surfaces of the intermediate meandering section are all arcuately arranged.

[0167] As Figures 19 to 22 In the illustrated embodiment, the intermediate meandering section 22424 includes a partition strip 22426 extending along the intermediate meandering section 22424 along the width center line of the intermediate meandering section 2424. Optionally, the partition strip extends substantially along the entire length of the intermediate meandering section and is spaced apart from the inflow section and the outflow section, for example, extending within the range of 10% (±8%) to 90% (±8%) of the intermediate meandering section. Optionally, the partition strip is configured to be able to closely adhere to the high-voltage discharge device. In these embodiments, the endpoints of the partition strip are arranged adjacent to the inflow section and the outflow section, seemingly causing unstable air flow but obtaining a more efficient ozone production efficiency.

[0168] As Figures 19 to 22 In the illustrated embodiment, the intermediate meandering section 22424 has a wider width and a smaller depth than the inflow section 22420 and / or the outflow section 22421. Preferably, the ratio of the width of the intermediate meandering section to the width of the inflow section and / or the outflow section is greater than 2:1, preferably between 3:1 and 10:1. Optionally, the ratio of the depth of the intermediate meandering section to the depth of the inflow section and / or the outflow section is less than 1:2, preferably between 1:3 and 1:10. Such a width / depth ratio can effectively obtain a higher gas production efficiency.

[0169] As Figures 19 to 22 In the illustrated embodiment, the ground electrode 224 is a first-end ground electrode, and the plate body of the first-end ground electrode has only the contact surface and the micro-air channel on the first surface, and the second surface of the plate body constitutes an end face.

[0170] As Figures 19 to 22In the illustrated embodiment, the plate body of the first end ground electrode 224 further includes an air inlet hole 2245 located on the first side and extending from the second surface toward the first surface, and an air outlet hole 2246 located on the second side and extending from the second surface toward the first surface. In the illustrated embodiment, the air inlet hole 2245 and the air outlet hole 2246 penetrate the plate body and communicate with the longitudinal air grooves. For example, the air inlet hole 2245 intersects with the first longitudinal air groove 2243 such that the outer longitudinal side of the first longitudinal air groove 2243 extends through the diameter of the air inlet hole 2245, and the air outlet hole 2246 intersects with the second longitudinal air groove 2244 such that the outer longitudinal side of the second longitudinal air groove 2244 extends through the diameter of the air outlet hole 2246.

[0171] Reference Figures 23 to 26 , a ground electrode 225 of another embodiment is shown. The ground electrode 225 is a second end ground electrode. The plate body of the second end ground electrode has only the contact surface and the micro air channels on the second surface, and the first surface of the plate body forms an end face.

[0172] Similar to the ground electrode 224, the ground electrode 225 also has a micro air channel 2252 that extends tortuously from the first longitudinal air groove to the second longitudinal air groove. Similarly, the micro air channel 2252 may include an inflow section 22520 adjacent to the first longitudinal air groove, an outflow section 22521 adjacent to the second longitudinal air groove, and an intermediate tortuous section 22524 between the inflow section and the outflow section. Similarly, the intermediate tortuous section 22524 includes a partition strip 22526 that extends along the width center line of the intermediate tortuous section 22524. The difference is that these micro air channel related features are formed on the second surface.

[0173] The micro air channels and longitudinal air grooves of the ground electrode 225 may be similar to those of the ground electrode 224, but are flip-symmetrical. The difference is that the ground electrode 225 does not have air inlet / outlet holes. In addition, the ground electrode 225 may further include a receiving groove in the second surface for receiving the connector head of the high-voltage discharge device.

[0174] Although not shown in the drawings, in some embodiments, a pair of ground electrodes for an ozone generator is provided, which includes stacked, for example Figures 19 to 26 the above-mentioned first end ground electrode and second end ground electrode of the illustrated embodiment. In these embodiments, the first longitudinal air grooves of the pair of end ground electrodes are connected and communicated in the stacking direction, and the second longitudinal air grooves of the pair of end ground electrodes are connected and communicated in the stacking direction.

[0175] In a preferred embodiment, in the projection on a plane, the first longitudinal groove and the air inlet hole of the first end ground electrode are located within the envelope of the first longitudinal groove of the second end ground electrode, and the second longitudinal groove and the air outlet hole of the first end ground electrode are located within the envelope of the second longitudinal groove of the second end ground electrode. This can improve the gas production efficiency.

[0176] Although not shown in the drawings, in some embodiments, a plate-type ozone generation module is provided, which includes the above-mentioned ground electrode pairs stacked and a high-voltage discharge device located between adjacent ground electrodes.

[0177] Reference Figure 27 and Figure 28 shows a high-voltage discharge device 24 according to an embodiment of the present invention. In the shown embodiment, the high-voltage discharge device 24 may include a connection head 242 for electrically connecting a high-voltage fuse device (for example, the connection is achieved by means of a plug), a high-voltage electrode plate 246, and a pair of dielectric plates 244 located on both sides of the electrode plate.

[0178] In some embodiments, the high-voltage discharge device 24 is used to generate a high-voltage corona discharge to cause a gas to react in the micro-air channels of the ground electrode to generate ozone. The principle and component composition of the high-voltage discharge device will not be elaborated here.

[0179] In some embodiments, the high-voltage discharge device 240 may have a width wider than the contact surface of the ground electrode, and thus extend into the longitudinal air grooves on both sides and partially cover the longitudinal air grooves on both sides.

[0180] Reference Figures 29 to 32 , shows an embodiment of a high-voltage fuse device 23 for an ozone generator. The shown high-voltage fuse device 23 may include a first wire 2321 at the first end; a second wire 2322 at the second end; a fuse tube 2325; a heat-conducting insulating plate 2326 provided in the fuse tube 325; at least one (shown as a circumferentially fully wrapped one) insulating heat-insulating film 2327; a fuse wire 2328 extending in the sealed cavity and connecting the first wire and the second wire, and extinguishing particles 2329 or extinguishing fluid installed in the fuse tube 2325. The extinguishing particles 2329 are, for example, quartz sand. In the shown embodiment, the high-voltage fuse device 23 may further include a first elastic insulating sheath 2323 sleeved on the fuse tube at the first end and a second elastic insulating sheath 2324 sleeved on the fuse tube at the second end.

[0181] As Figure 29 and Figure 31As shown, at least one piece of insulating and heat-insulating film 2327 covers the heat-conducting insulating plate 2326 to enclose a sealed cavity. Thus, the high-voltage fuse device for an ozone generator according to an embodiment of the present invention can have the ability to work stably for a long time and has extremely high safety. By way of explanation and not limitation, in particular, by means of the heat-conducting insulating plate, on the one hand, it can allow the high temperature that is in harsh conditions and usually causes the fuse to quickly conduct heat out through the heat-conducting insulating plate, and can also ensure that the heat-conducting medium insulating plate maintains high structural stability; on the other hand, it can also effectively conduct the extremely high temperature that may be caused when the fuse is overloaded and fails to the entire heat-conducting insulating plate, so that the insulating and heat-insulating film melts and forms extinguishing particles or extinguishing fluid to cover the fuse, avoiding causing a fire or quickly extinguishing the generated combustion as soon as possible.

[0182] As Figure 32 shown, the heat-conducting insulating plate 2326 may include a plurality of long holes 23260, 23262, 23264 (for example, an odd number, here 3) arranged at intervals in the axial direction and the spaced portions 23266, 23267 located between the plurality of long holes. In some embodiments, the fuse extends along the plurality of long holes and straddles the spaced portions. Thus, the working stability and structural strength of the high-voltage fuse device can be greatly improved by the fuse extending in the long holes and straddling the spaced portions. In Figure 31 the embodiment shown, the fuse extends along the plurality of long holes and alternately straddles the spaced portions on the top surface and the bottom surface of the heat-conducting insulating plate. This can further balance the fuse structure loading and provide higher working stability and structural length.

[0183] As Figure 32 shown, the long holes 23260, 23262, 23264 may include positioning acute angles 23261, 23263, 23265 located at the axial ends. With the help of the positioning acute angles, the working stability of the high-voltage fuse device can be further improved, which especially enables the wires and the fuse at both ends to be better aligned.

[0184] As Figure 32 shown, the high-voltage fuse device further includes two electrical connection portions 23268, 23269 located at both ends of the heat-conducting insulating plate, for electrically connecting the two ends of the fuse to the first wire and the second wire respectively. With reference to Figure 29 and Figure 31 , the electrical connection portions 23268, 23269 are covered between the heat-conducting insulating plate and the insulating and heat-insulating film. This covered electrical connection portion can prevent the connection part from becoming the main heat conduction part of the fuse failure, which is believed to significantly improve the working stability of the high-voltage fuse device. Preferably, the electrical connection portion is welding, such as soldering.

[0185] In one embodiment, the thermally conductive insulating plate is made of a high-temperature resistant inorganic dielectric material, preferably made of ceramic.

[0186] In one embodiment, the fuse tube is transparent, preferably a transparent quartz tube. This can provide better failure monitoring capabilities for operators or monitoring devices.

[0187] In some embodiments, the insulating and heat-insulating film may have a melting point higher than that of the fuse wire.

[0188] Unless explicitly stated, the methods or steps described according to the embodiments of the present invention do not necessarily have to be executed in a specific order and can still achieve the desired results. In certain embodiments, multitasking and parallel processing are also possible or may be advantageous.
