Description

Technical Field

[0001] This invention relates to the field of ozone generators, and more specifically to a ground electrode for ozone generators. Background Technology

[0002] Ozone is a strong oxidant that can effectively sterilize, and therefore it is widely used in fields that require sterilization or disinfection, such as environmental protection, medical and health care, water treatment, pharmaceuticals, food preparation, and cosmetics preparation.

[0003] To address this, various ozone generators and related devices have been proposed, which typically utilize electrical discharges to generate low-temperature plasma gas.

[0004] Common types of ozone generators include tubular, tank-type, or cabinet-type ozone generators. However, these ozone generators are often customized to specific needs, resulting in poor scalability. Furthermore, these ozone generators are typically part of large-scale equipment or auxiliary equipment, failing to flexibly meet diverse user requirements. The inventors have also discovered certain scalable plate-type ozone generators.

[0005] As a crucial component of plate-type ozone generators, there is a current need to continuously improve the structure of plate-shaped ground electrodes in order to achieve more efficient ozone production.

[0006] The above description is provided only as background information for understanding the relevant technologies in this field and does not constitute an admission that it belongs to the prior art. Summary of the Invention

[0007] Therefore, it is desirable to provide a ground electrode that can further improve gas production efficiency, as well as an ozone generating unit and an ozone generator having the ground electrode.

[0008] In a first aspect, a ground electrode is provided, comprising a one-piece body, the ground electrode further comprising a reaction zone formed within at least one of the first and second surfaces of the one-piece body and a plurality of planar grooves extending laterally in the reaction zone, each planar groove comprising a first curve at a first end and a second curve at a second end, the ground electrode further comprising an inlet micro-hole and an outlet micro-hole located within the envelope of each planar groove, the inlet micro-hole being disposed near the first end and the outlet micro-hole being disposed near the second end, the one-piece body further comprising a first air passage communicating with the inlet micro-hole, a second air passage communicating with the outlet micro-hole and a cooling passage.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0044] In the description of the "ground electrode" and the "high-voltage discharge assembly" and their plate-like components herein, "surface" refers to the side of the extended surface of the plate-like component, also known as the "(plate) surface," and is not limited to a plane and may have different heights (e.g., recesses or protrusions) on the same "surface." Furthermore, it is conceivable that the ozone generating unit described in the embodiments of this application may be defined in multiple different directions based on the orientation of the ground electrode, such as lateral, vertical, and longitudinal, wherein the lateral direction can be the width direction of the ground electrode, the vertical direction can be the height direction of the ground electrode, and the longitudinal direction can be the thickness direction or stacking direction of the ground electrode.

[0045] The embodiments shown in the accompanying drawings will be described below with reference to the accompanying drawings.

[0046] In several embodiments of the present invention, an ozone generator is provided, such as a gas corona discharge type ozone generator, which in particular includes one or more plate ozone generating units.

[0047] refer to Figures 1A to 1G An ozone generator 1 according to an embodiment of the present invention is shown, which, as shown, is, for example, an integrated ozone generator. The integrated ozone generator 1 includes a housing 10. The housing 10 may include a front panel 11, a rear panel 12, a top panel 13, a base 14, and side panels.

[0048] Continue to refer to Figures 1A to 1G According to embodiments of the present invention, the various functional components can be housed in the integrated ozone generator. The ozone generator 1 may include an ozone generating unit 2, a high-voltage terminal block 3 for the ozone generating unit 2, and various electrical components.

[0049] In the illustrated embodiment, the ozone generating unit 2 may include a plurality of stacked ground electrodes 20 and a high-voltage discharge unit 21 disposed between the ground electrodes 20. Embodiments of the plate-type ozone generating unit will be further described below.

[0050] like Figures 1A to 1G As shown, the enclosure of the ozone generator 1 may include a partition 16, which can be installed within the enclosure to separate an electrical chamber and a gas generation chamber that are isolated from each other. For example, the partition 16 may be horizontally installed within the enclosure to separate an upper chamber serving as the electrical chamber and a lower chamber serving as the gas generation chamber, wherein the plate-type ozone generating unit 2 is installed in the gas generation chamber, and a plurality of electrical components are installed in the electrical chamber. In some embodiments, the partition 16 is installed within the enclosure such that the electrical chamber and the gas generation chamber are electromagnetically isolated from each other. In some embodiments, the partition 16 may be made of a non-metallic shielding material. Further, the enclosure may also include at least a front guard plate, a rear guard plate, a pair of side guard plates, and / or a top guard plate (not shown) made of a non-metallic shielding material disposed within the electrical chamber. The guard plates may be formed separately; alternatively, the guard plates may be integrated into the front panel, rear panel, or side panel, or the front panel, rear panel, or side panel may have a guard plate function, for example, being at least partially made of a non-metallic shielding material or having a shielding layer. Optionally, the partition 16 is installed in the enclosure such that the electrical compartment and the gas generation compartment are moisture-proof and / or explosion-proof to each other.

[0051] Continue to refer to Figures 1A to 1GThe enclosure can accommodate various necessary electrical components. These components include, but are not limited to, a power supply module 6, a high-voltage transformer 7 electrically connected to the power supply module, a resonant inductor 8 electrically connected to the high-voltage transformer, and a filter reactor 9. In some embodiments, the resonant inductor 8 is connected to the high-voltage terminal block 3, for example, via a high-voltage bus. In some embodiments, the current output from the power supply module 6 is boosted through the high-voltage transformer 7 and the resonant inductor 8 to achieve the high voltage required by the plate-type ozone generator module 2.

[0052] It will be understood that ozone generators may optionally be equipped with the aforementioned or other processing circuits, transformer mechanisms, and / or power conversion modules, as well as other functional components related to the power supply and monitoring of the ozone generator, which will not be elaborated upon here.

[0053] Continue to refer to Figures 1A to 1G The ozone generator 1 may include an inlet port 126 and an outlet port 127 for cooling fluid, which are provided on the rear panel 12. The ozone generator 1 may also include an air inlet port 128 and an air outlet port 129, which are provided on the rear panel 12. The ozone generator 1 may also include a communication interface 121 and a power connector 122, which are provided on the rear panel 12.

[0054] Continue to refer to Figures 1A to 1G The ozone generator 1 may include a touch panel 110 and a power button 111 disposed on the front panel 11. (Continue to the previous section) Figures 1A to 1G The ozone generator 1 may include a heat dissipation device 131 (such as a cooling fan) disposed on the top panel 13.

[0055] People will understand that the ozone generating unit (also referred to as "ozone generating module") of the present invention can be applied not only to, for example... Figures 1A to 1G The integrated ozone generator shown can also be applied to other types of ozone generators or combinations or arrays of different ozone generators, which fall within the scope of this invention.

[0056] For example, in another embodiment, a rack-mounted ozone generator may be provided, which may include a rack, multiple ozone generating units, a gas distribution system, and a cooling fluid distribution system. In this rack-mounted ozone generator, the multiple ozone generating units may share one or more sets of electrical components.

[0057] For example, in another embodiment, an ozone generating device combining a rack and integrated ozone generators can be provided, which may include multiple integrated ozone generators, a mounting platform, and a gas distribution system and a cooling fluid distribution system shared by the multiple integrated ozone generators.

[0058] Reference Figures 2A-13CThis document describes an ozone generating unit 2 according to a first embodiment of the present invention. In the illustrated embodiment, the ozone generating unit 2 may be configured as a plate-type ozone generating unit, and it may be modular, and may also be referred to herein as an ozone generating module.

[0059] In the illustrated embodiment, the ozone generating unit 2 may include multiple stacked ground electrodes, which are plate-type ground electrodes, as described below. Figures 3A to 4D As stated above.

[0060] Ozone generating unit 2 may also include a high-voltage discharge assembly disposed between the ground electrodes, as described below. Figures 3A to 3C as well as Figures 5A to 10B As stated above.

[0061] Accordingly, such as Figures 3A to 3C As shown, the ground electrode 20 and the high-voltage discharge assembly 21 can together form a discharge chamber for the discharge reaction.

[0062] In the illustrated embodiment, the ozone generating unit 2 may further include a first end cap 22 located at the first end and a second end cap 23 located at the second end.

[0063] like Figures 2A to 2C As shown, the ozone generating unit 2 may further include an inlet pipe 260, an outlet pipe 270, an air inlet pipe 280, and an exhaust pipe 290 connected to the first end cap 22. The inlet pipe 260, outlet pipe 270, air inlet pipe 280, and exhaust pipe 290 define an inlet port 126, an outlet port 127, an air inlet port 128, and an air outlet port 129.

[0064] Earth electrode

[0065] Continue to refer to Figures 3A to 4D The invention describes a plurality of stacked plate ground electrodes 20 according to some embodiments of the invention. In the illustrated embodiments, the plate ground electrode 20 may include a single-piece or integral body. The body of the plate ground electrode 20 may be made of an aluminum alloy coated with a nano-ceramic material.

[0066] like Figure 4A and Figure 4CAs shown, the ground electrode 20 may include a reaction region 2000 formed within at least one of a first surface 201 and a second surface 202 of the monolithic body 200, and a plurality of planar grooves 2010 extending laterally within the reaction region. In the illustrated embodiment, the reaction region 2000 is formed only on the first surface 201. In embodiments of the invention, the planar grooves 2010 may also be referred to as planar (micro)grooves, thereby allowing the planar grooves 2010 to form gas (micro)channels with extremely high aspect ratios together with the dielectric plate 216 of the high-voltage discharge assembly 21. In some preferred embodiments, the aspect ratio of the planar (micro)grooves 2010 is, for example, 10:1 to 200:1, more preferably 20:1 to 200:1, and even more preferably 50:1 to 150:1.

[0067] like Figure 4A and Figure 4C As shown, each planar groove 2010 includes a first curve located at the first end 2013 and a second curve located at the second end 2014. Specifically, the first curve 2015 can be a first parabolic curve 2015, and the second curve 2016 can be a second parabolic curve 2016.

[0068] like Figure 4A and Figure 4C As shown, the ground electrode 20 may further include an inlet micro-hole 2011 and an outlet micro-hole 2012 located within the envelope of each planar groove 2010. The inlet micro-hole 2011 is disposed near the first end 2013, and the outlet micro-hole 2012 is disposed near the second end 2014. Figure 4A and Figure 4C In the illustrated embodiment, the air inlet micro-orifice 2011 is generally located at the focal point of the first parabolic curve. More specifically, the center of the air inlet micro-orifice 2011 may approximately coincide with the focal point of the first parabolic curve. Similarly, the air outlet 2012 is generally located at the focal point of the second parabolic curve. More specifically, the center of the air outlet 2012 may approximately coincide with the focal point of the second parabolic curve.

[0069] In the embodiments of this application, the "micro-orifice" can be specifically determined according to the size of the ground electrode 20, for example, it can be less than or equal to 2 mm. In a preferred embodiment, the air inlet micro-orifice 2011 has a pore size of 0.1 mm to 1 mm, preferably 0.2 mm to 0.5 mm, and more preferably 0.2 mm to 0.3 mm.

[0070] In this embodiment, the thickness of the ground electrode can be determined based on the constraint of the micropores, thereby obtaining a thin ground electrode. Preferably, in Figures 2A to 13CIn the illustrated embodiment, the ratio of the thickness of the monolithic body of the ground electrode to the aperture of the air inlet micro-orifice is greater than or equal to 5 and less than or equal to 20, preferably greater than or equal to 6 and less than or equal to 16, more preferably greater than or equal to 8 and less than or equal to 15; preferably, the monolithic body has a thickness of 3 mm to 15 mm, preferably 3 mm to 10 mm, more preferably 4 mm to 6 mm. It will be understood that the intersection of both can be taken. In the illustrated preferred embodiment, the air inlet micro-orifice can have a thickness of 0.3 mm, and the ratio of the thickness of the monolithic body to the aperture of the air inlet micro-orifice can be 13.3.

[0071] As described herein, the exhaust port 2012 may not be limited to a "micro-orifice" and may have a wider range of aperture sizes. In a preferred embodiment, the aperture ratio of the exhaust port 2012 to the intake micro-orifice 2011 is in the range of 1.5 to 15, preferably in the range of 2 to 10, and more preferably in the range of 2 to 8.

[0072] like Figure 4A and Figure 4C As shown, the reaction zone 2000 is generally rectangular, and the one-piece body 200 of the ground electrode 20 can also form a reaction zone surrounding groove 2019 defining the reaction zone 2000 on the first surface 201. Thus, features on the first surface 201 located outside the reaction zone 2000 will be sealed and isolated from the reaction zone 2000.

[0073] like Figure 4A and Figure 4C As shown, the ground electrode 20 also includes a first pressure balancing structure. This first pressure balancing structure is in the form of a trench. Specifically, the ground electrode 20 includes a diversion trench 2018 located within the reaction zone 2000, symmetrically connected at its first end 2013 to one or more planar grooves 2010. For example... Figure 4A and Figure 4C As shown, the diversion groove 2018 connects the topmost planar groove 2010 and the bottommost planar groove 2010. (Refer to reference...) Figures 3A to 5B The diversion trench 2018 extends beyond the envelope of the dielectric plate 216 of the high-voltage discharge assembly 21 to divert the reactive gas within the corresponding planar groove 2010 to the high-voltage discharge assembly 21, as further described below.

[0074] Continue to refer to Figure 4A and Figure 4C Preferably, all planar grooves 2010 are "almost" closed, except for the diversion grooves 2018.

[0075] The following section continues to describe other fluid flow structures of the ground electrode 20.

[0076] Continue to refer to Figures 4A to 4DAs shown, outside the reaction zone 2000, the ground electrode 20 also includes a plurality of through holes that serve as part of the fluid supply channel of the ozone generating unit 2. For example, these are a first air inlet through hole 282 that serves as part of the air inlet channel, a first exhaust through hole 292 that serves as part of the exhaust channel, a first inlet flow hole 262 that serves as part of the inlet flow channel, and a first exhaust flow hole 272 that serves as the exhaust flow channel.

[0077] like Figure 4B and Figure 4D As shown, the single-piece body 200 may also form a first air passage 2021 communicating with the air inlet micro-hole 2011, a second air passage 2022 communicating with the air outlet 2012, and a cooling passage 2020 on the second surface 202, all of which are open passages. Here, the cooling passage 2020 has a tortuous structure, for example, an M-shape.

[0078] Specifically, such as Figure 4B and Figure 4D As shown, the first air passage 2021 is orthogonal to the first air inlet hole 282, the second air passage 2022 is orthogonal to the first exhaust hole 292, one end of the cooling passage 2020 is orthogonal to the first air inlet hole 262, and the other end is orthogonal to the first exhaust hole 272. The air inlet micro-hole 2011 connects the first air passage 2021 and the corresponding planar groove 2010, and the exhaust hole 2012 connects the corresponding planar groove 2010 and the second air passage 2022.

[0079] like Figure 4B and Figure 4D As shown, the first air passage 2021 on the second surface 202 is connected to the inlet micro-orifice 2011 on the first surface 201 via a stepped hole structure 2026. The diameter of the stepped hole structure 2026 is larger than the diameter of the inlet micro-orifice 2011. Specifically, the stepped hole structure 2026 is a single-stage or multi-stage stepped hole, and the diameter of the single-stage stepped hole or the first stage diameter of the multi-stage stepped hole can be approximately equal to the diameter of the exhaust hole 2012. Figure 4B and Figure 4D In the embodiment shown, the stepped hole structure 2026 is a single-stage stepped hole.

[0080] Therefore, as Figures 3A to 4D As shown, the first air inlet 282, the first air passage 2021, each air inlet micro-hole 2011, each planar groove 2010, each exhaust hole 2012, the second air passage 2022 and the first exhaust 292 form the airflow distribution structure in the ground electrode 20 in sequence.

[0081] like Figure 4A and Figure 4CAs shown, the ground electrode 20 forms a surrounding groove around the first air inlet hole 282, a surrounding groove around the first exhaust hole 292, a surrounding groove around the first air inlet hole 262, and a surrounding groove around the first exhaust hole 272 on the first surface 201.

[0082] Similarly, such as Figures 3A to 4D As shown, the inlet flow hole 262, the tortuous cooling channel 2020, and the outlet flow hole 272 form the cooling flow distribution structure in the ground electrode 20 in sequence.

[0083] like Figure 4B and Figure 4D Combination Figure 11 and Figure 12 As shown, the second surface 202 of the single-piece body 200 may also form a first air passage surrounding groove 2024 surrounding the first air passage 2021 and the air inlet 282, a second air passage surrounding groove 2025 surrounding the second air passage 2022 and the exhaust 293, and a cooling flow surrounding groove 2023 surrounding the air inlet 262, the cooling passage 2020, and the exhaust 272. Accordingly, a first air passage surrounding seal 204 may be installed in the first air passage surrounding groove 2024, a second air passage surrounding seal 205 may be installed in the second air passage surrounding groove 2025, and a cooling flow surrounding seal 203 may be installed in the cooling flow surrounding groove 2023.

[0084] In the illustrated embodiment, as Figures 2A to 2C As shown, the ground electrodes 20 can be abutted with their second surfaces 202 such that the first air passages 2021 of the pair of ground electrodes 20 together form a circumferentially closed first airflow space, the second air passages 2022 together form a circumferentially closed second airflow space, and the cooling passages 2020 together form a circumferentially closed cooling flow space. Thus, the aligned first air passage surrounding grooves 2024 of the abutted pair of ground electrodes 20 can jointly accommodate the first air passage surrounding seal 204, the aligned second air passage surrounding grooves 2025 can jointly accommodate the second air passage surrounding seal 205, and the aligned cooling flow surrounding grooves 2023 can jointly accommodate the cooling flow surrounding seal 203.

[0085] As shown in the figure, the first air passage surrounding groove and the cooling flow surrounding groove share a common section; the second air passage surrounding groove and the cooling flow surrounding groove share a common section. Preferably, the first air passage surrounding seal and the cooling flow surrounding seal have a slightly larger width in the common section to form a compression seal in the common section; the second air passage surrounding seal and the cooling flow surrounding seal have a slightly larger width in the common section to form a compression seal in the common section.

[0086] These seals can serve as alignment and positioning structures when ozone generating units are grouped together, as further described below.

[0087] In addition, several first bolt holes 207 can be formed in the ground electrode 20.

[0088] The following text is based on references. Figures 3A to 3C as well as Figures 5A to 10B This describes the high-voltage discharge component of ozone generation unit 2.

[0089] like Figures 2A to 3C In the illustrated embodiment, the high-voltage discharge assembly 21 is placed between the first surfaces of adjacent ground electrodes 20.

[0090] like Figures 3A to 3C as well as Figures 5A to 10B As shown, the high-voltage discharge assembly 21 may include an elastic frame member 210 and a pair of dielectric plates 216 on both sides. In addition, the high-voltage discharge assembly 21 may also include an elastic pad assembly.

[0091] like Figures 5A to 6D As shown, the elastic frame member 210 includes a connector portion 2110, a terminal held by the connector portion and extending from the top of the connector portion, and a pair of elastic contact pieces 2111 electrically connected to the terminal, the pair of elastic contact pieces electrically contacting the back side of the pair of dielectric plates 216. The connector portion 2110 can be accommodated in the limiting groove 2017 ( Figure 4C )middle.

[0092] For details, please refer to the following: Figures 6A to 6D The elastic frame member 210 may have a frame structure defining a pressure balance region 2100 located on the back side of the pair of dielectric plates 216. The elastic frame member also includes a second pressure balance structure comprising one or more pressure balance grooves 2102, 2103, 2104 disposed near the air inlet end of the ground electrode 20, the pressure balance grooves having at least one, preferably at least one pair, and preferably symmetrically arranged openings on a first side of the pressure balance region 2100 near the air inlet end. Figures 6A to 6D In the illustrated embodiment, the pressure balancing trench specifically includes a first pressure balancing trench 2102 that extends at least partially beyond the envelope of the dielectric plate 216 and a plurality of second pressure balancing trenches 2103, 2104, the first ends of the plurality of (2) second pressure balancing trenches being connected to the first pressure balancing trench 2103. (Referring to the reference...)

[0093] As shown in the figure, several laterally extending balancing channels will be provided in the pressure balancing zone 2100. In the illustrated embodiment, the balancing channels are provided by an elastic pad assembly.

[0094] refer to Figures 7A to 9C The elastic pad assembly includes an elastic pad 212 and heat-conducting plates 214 located on both sides of the elastic pad. The heat-conducting plates 214 are preferably bonded to the elastic pad 212, for example by accommodating adhesive in the gap area 2123 between the elastic protrusions 2122 of the elastic pad 212. The adhesive may be, for example, a thermally conductive adhesive.

[0095] As shown in the figure, the elastic pad assembly 212 is floatingly mounted in the thickness direction within the pressure balance zone 2100 of the elastic frame member 210. Specifically, as... Figures 5A to 6D As shown, the elastic frame member 210 includes a plurality of positioning bosses 2105, which are preferably vulcanized. For example... Figures 5A to 5B and Figures 7A to 7C As shown, the elastic pad assembly 212 includes multiple positioning notches for mounting to the plurality of positioning bosses 2105. Accordingly, the elastic pad 212 may have positioning notches 2125, and the heat-conducting plate 214 may also have positioning notches 2145. The body 2140 of the heat-conducting plate 214 is made of a thermally conductive metal, such as stainless steel, and may be subject to suitable material treatment.

[0096] like Figures 5A to 5B The elastic pad assembly is floatingly mounted in the thickness direction, such that the elastic pad assembly is spaced apart from the frame structure of the elastic frame member 210 to form a first gap G1 on the first side of the pressure balance zone 2100 and a second gap G2 on the opposite second side. Furthermore, gaps may also be formed at the top and bottom of the elastic pad assembly.

[0097] refer to Figures 7A to 8B The elastic pad 212 includes a plurality of balancing grooves 2121, preferably two sets of balancing grooves 2121 located on both sides of the elastic pad. Each balancing groove 2121 has an open first end and a second end. In this embodiment, the open first end and the second end have end openings 2126 and 2127. In this embodiment, the plurality of balancing grooves and the corresponding heat-conducting plate 214 form a plurality of balancing channels for balancing gas flow. (Refer to reference...) Figures 4A to 4D as well as Figures 7A to 8BThe number of the plurality of balancing grooves 2121 of the elastic pad 212 corresponds to the number of planar grooves 2010 of the ground electrode 20 for the reaction of the reactive gas, and at least some of the balancing grooves have a shape substantially the same as the corresponding planar grooves.

Correspondingly, the elastic pad 212 may have a notch 2124, and the heat-conducting plate 214 may also have a notch 2144. (Refer to reference...) Figures 4A to 4D as well as Figures 7A to 8B The shape of the balancing groove, except for the notch, is approximately the same as the shape of the corresponding planar groove.

[0099] Continue to refer to Figures 10A to 10B The dielectric substrate 216 has a single-piece body 2160 and includes a front side facing the ground electrode and a back side facing away from the ground electrode. The dielectric substrate 216 has a conductor-coated region 2161 on the back side that is in electrical contact with the elastic contact piece, and an enamel-coated region 2162 on the front side facing the reaction region. The dielectric substrate 216 also includes an uncoated edge region 2163 surrounding the conductor-coated region 2161. The conductor-coated region 2161 may be a silver-coated region. (Refer to reference...) Figures 3A to 3C as well as Figure 10A and Figure 10B The uncoated edge region 2163 is configured such that the conductor coating region 2161 is spaced apart from the frame structure of the frame member 210, and the heat-conducting plate 214 of the elastic pad assembly substantially covers the conductor coating region 2161, thereby forming a surface discharge suppression structure.

[0100] Furthermore, as mentioned above, the elastic pad assembly and the frame structure of the frame member 210 form gaps G1, G2, etc., thereby forming a further surface discharge suppression structure.

[0101] refer to Figures 5A to 6D The elastic frame member 210 of the high-voltage discharge assembly 21 may include a second air inlet 283, a second exhaust 293, a second inlet flow hole 263, and a second outlet flow hole 273 located outside the dielectric plate 216.

These sealing ridges may engage with corresponding surrounding grooves of adjacent ground electrodes of the ground electrode 20.

[0102] These sealing protrusions can also serve as alignment and positioning structures for the ground electrode 20 and the high-voltage discharge assembly 21.

[0103] Continue to refer to Figures 5A to 6D and Figures 13A to 13C The high-voltage discharge assembly 21 also includes pad holes 2117 and 2118 located in the elastic frame member 210 and rigid pads 217 and 218 for being accommodated in the pad holes.

The rigid pads 217 at the top and bottom of the elastic frame member 210 and the corresponding pad holes 2117 are circular.

[0104] refer to Figures 5A to 6D The elastic frame 210 of the high-voltage discharge assembly 21 may also include a second bolt through hole 2116.

[0105] refer to Figures 5A to 6D The elastic frame 210 of the high-voltage discharge assembly 21 may also have a surrounding ridge 2119, which can be accommodated within the surrounding groove 2019 of the reaction zone to provide a seal.

[0106] The following will refer to Figures 2A to 13C The installation (grouping) of the ozone generating unit 2 according to the first embodiment of this application, as well as the corresponding alignment and sealing, are described.

[0107] In the assembled ozone generating unit 2, ground electrodes 20 are arranged in pairs, with the pairs of ground electrodes 20 attached to the second surface 202, and adjacent pairs of ground electrodes 20 facing each other on the first surface 201 and sandwiched with a high-voltage discharge component 21, thereby forming a discharge chamber between the first surfaces 201 of the opposing ground electrodes 20 (and the high-voltage discharge component 21). Figures 2A to 2C As best shown, the elastic frame member 210 (frame structure) of the high-voltage discharge assembly 21 also constitutes part of the thickness of the ozone generating unit 2.

[0108] The assembly of ozone generating unit 2 is described below. First, the second end cap 23 can be placed on a flat surface, and the ground electrode 20 and the high-voltage discharge component 21 can be stacked in the manner described above (e.g., except for the end ground electrode 20, a high-voltage discharge component 21 is stacked after every two ground electrodes 20). At this time, the mating ground electrodes 20 and adjacent high-voltage discharge components 21 are pre-aligned by means of an alignment and positioning structure. This alignment and positioning structure includes, but is not limited to, the first air passage surrounding seal 204 housed in the first air passage surrounding groove 2024 of the mating ground electrodes 20, the second air passage surrounding seal 205 in the second air passage surrounding groove 2025 of the mating ground electrodes 20, the cooling flow surrounding seal 203 in the cooling flow surrounding groove 2023 of the mating ground electrodes 20, and the sealing ridge 2113 surrounding the second air inlet hole 283, the sealing ridge 2114 surrounding the second exhaust hole 293, the sealing ridge 2115 surrounding the second air inlet hole 263, and the sealing ridge 2116 surrounding the second exhaust hole 273. Figure 3B and Figure 4B As shown, the alignment and positioning structure on the second surface 202 accounts for at least 60%, preferably 70%-90%, of the lateral dimension and at least 60%, preferably 70%-90%, of the vertical dimension of the monolithic body 200.

[0109] After the ground electrode 20 and the high-voltage discharge assembly 21 are stacked, the first end cap 22 can be pressed tightly at the top, thereby ensuring that the aforementioned alignment and positioning structure is precisely self-aligned due to the pressing. Figure 2C Ideally, the clamping of the first end cap 22 is achieved by gravity, for example, the weight (or thickness) of the first end cap 22 is more than twice, preferably more than five times, that of the ground electrode 20. It will be understood that the first end cap 22 and the second end cap 23 are used here only to distinguish different end caps, and not to limit the use of a particular end cap for clamping.

[0110] Subsequently, the bolt can be tightened by passing through the first end cover 22, the ground electrode 20 and the high-voltage discharge assembly 21 into the bolt through hole 221 of the second end cover 23 through the thread provided in the bolt through hole 221.

[0111] Through the above assembly process, the various components of ozone generating unit 2 can be precisely aligned and sealed, thereby ensuring the performance and stability of the equipment.

[0112] The fluid supply (discharge) of the assembled ozone generator and the fluid distribution within the electrodes in various locations will be described below.

[0113] Reference Figure 2A and Figure 3CThe first air inlet holes of the local electrodes and the second air inlet holes of each high-voltage discharge component of the installed ozone generating unit are aligned along the stacking direction to form an air inlet channel spanning the local electrodes, and the air inlet channel is configured to be axially aligned with the air inlet pipe of the ozone generating unit. Similarly, the first exhaust holes of the local electrodes and the second exhaust holes of each high-voltage discharge component of the installed ozone generating unit are aligned along the stacking direction to form an exhaust channel spanning the local electrodes, and the exhaust channel is configured to be axially aligned with the exhaust pipe of the ozone generating unit. Similarly, the first flow inlet holes of the local electrodes and the second flow inlet holes of each high-voltage discharge component of the installed ozone generating unit are aligned along the stacking direction to form a flow inlet channel spanning the local electrodes, and the flow inlet channel is configured to be axially aligned with the flow inlet pipe of the ozone generating unit. Similarly, the first drain holes of the local electrodes and the second drain holes of each high-voltage discharge component of the installed ozone generating unit are aligned along the stacking direction to form a drain channel spanning the local electrodes, and the drain channel is configured to be axially aligned with the drain pipe of the ozone generating unit.

[0114] Here, the reacting gas enters the intake channel from the aforementioned intake pipe, then flows into the first gas path of each cross-passing ground electrode (the closely attached ground electrode pair), passes through the intake micro-holes, and enters the planar groove for reaction. The generated gas flows from the exhaust port to the second gas path, then into the exhaust channel, and finally into the exhaust pipe. Thus, the gas supply (exhaust) structure is not directly connected to the planar groove.

[0115] Similarly, the cooling fluid will enter the inlet channel from the aforementioned inlet pipe, then flow into the M-shaped cooling channel across each of the ground electrodes (closely adjacent ground electrode pairs), and then into the outlet pipe after flowing into the outlet channel. Thus, the cooling fluid branch pipes will be eliminated, and the cooling fluid supply and discharge will be provided by the inlet and outlet channels integrated into the ozone generating unit.

[0151] In this embodiment, the thickness of the ground electrode can be determined based on the constraint of the micropores, thereby obtaining a thin ground electrode. Preferably, in Figures 24-29BIn the third embodiment shown, the ratio of the thickness of the single-piece ground electrode body to the diameter of the air inlet micropore is greater than or equal to 10 and less than or equal to 35, preferably greater than or equal to 14 and less than or equal to 32, and more preferably greater than or equal to 16 and less than or equal to 30; preferably, the single-piece body has a thickness of 8 mm to 25 mm, preferably 10 mm to 20 mm, and more preferably 12 mm to 16 mm. It will be understood that the intersection of the two can be taken.

[0152] As described herein, the exhaust port 2012 may not be limited to a "micro-orifice" and may have a wider range of aperture sizes. In a preferred embodiment, the aperture ratio of the exhaust port 2012 to the intake micro-orifice 2011 is in the range of 1.5 to 15, preferably in the range of 2 to 10, and more preferably in the range of 2 to 8.

[0153] refer to Figure 24 and Figures 26A to 26F The reaction zone 2000” is roughly rectangular. The single-piece body 200” of the ground electrode 20” can also form reaction zone surrounding trenches 2019” and 2029 that define the reaction zone 2000” on both the first surface 201” and the second surface 202”.

[0154] refer to Figure 24 and Figures 26A to 26F The ground electrode 20" also includes a first pressure balancing structure. This first pressure balancing structure is in the form of a trench. In the illustrated embodiment, the first pressure balancing structure is formed only on the first surface, but it is conceivable that it could be formed on both surfaces. Specifically, the ground electrode 20" includes a diversion trench 2018 located within the reaction zone 2000, symmetrically connected at the first end 2013 to a planar groove 2010 (intermediate planar groove). The diversion trench 2018" extends only to the inlet micro-hole 2011 within the planar groove.

[0155] refer to Figure 24 and Figures 26A to 26F Preferably, all planar grooves 2010” on the first surface are almost closed, for example, except for the diversion groove 2018”; preferably, all planar grooves 2020” on the second surface are closed.

[0156] The following section continues to describe the other fluid flow structures of the ground electrode 20".

[0158] Unlike the first and second embodiments, reference is made to... Figure 24 and Figures 26A to 26F The ground electrode 20” may further include a first air passage 205” formed inside the one-piece body 200”, which is a vertical passage intersecting with the first air inlet hole.

The first vertical passage among the plurality of parallel vertical passages intersects with the first air inlet hole, and the second vertical passage intersects with the first exhaust hole.

[0159] refer to Figure 24 and Figures 26A to 26F The ground electrode 20” may also include an end (top and bottom) sealing groove 2001” for forming the above-mentioned transverse communication structure, a sealing cover for closing the end sealing groove 2001” at the end, and a pressing plate (not shown) for pressing the sealing cover.

[0160] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and associated alignment and positioning structure as described in the first or second embodiments may not be provided in the third embodiment.

[0161] In addition, several first bolt holes 207 can be formed in the ground electrode 20".

[0162] Ground electrode 25” can be formed similarly to ground electrode 20”, but the difference is that the first surface 251” of ground electrode 25” does not have a reaction zone and related features.

[0163] refer to Figure 24 and Figures 25A to 25F The ground electrode 25” may include a reaction region 2500 formed in the second surface 252” of the monolithic body 250”. The ground electrode 25” may include a plurality of planar grooves 2520 extending laterally in the reaction region.

[0164] The planar grooves 2520" on the second surface 252" include a first curve located at the first end 2523" and a second curve located at the second end 2524". Specifically, the first curve can be a first parabolic curve 2525", and the second curve can be a second parabolic curve 2526". Similarly, the ground electrode 25" may also include an inlet micro-hole 2521" and an outlet micro-hole 2522" located within the envelope of each planar groove 2520". The inlet micro-hole 2521" is located near the first end 2523", and the outlet micro-hole 2522" is located near the second end 2524". The inlet micro-hole 2521" is generally located at the focal point of the first parabolic curve. More specifically, the center of the inlet micro-hole 2521" may generally coincide with the focal point of the first parabolic curve. Similarly, the outlet micro-hole 2522" is generally located at the focal point of the second parabolic curve. More specifically, the center of the outlet micro-hole 2522" may generally coincide with the focal point of the second parabolic curve.

[0165] The structure and size of the air inlet micro-hole and air inlet hole of the ground electrode 25” can be referenced to the ground electrode 20”, but the air inlet micro-hole and air inlet hole of the ground electrode 25” in the third embodiment are provided in the second surface.

[0166] In the embodiments of this application, the thickness of the ground electrode can be determined based on the constraint of the micropores, thereby obtaining a thin ground electrode.

[0167] refer to Figure 24 and Figures 25A to 25F The reaction zone 2500” is roughly rectangular, and the single-piece body 250” of the ground electrode 25” can also form a reaction zone surrounding groove 2529 that defines the reaction zone 2500” on the second surface 252”.

[0168] refer to Figure 24 and Figures 25A to 25F Unlike ground electrode 20", ground electrode 25" does not have a first pressure balancing structure. However, it is conceivable that the first pressure balancing structure could be included in ground electrode 25".

[0169] refer to Figure 24 and Figures 25A to 25F Preferably, all planar grooves 2520 on the second surface are closed.

[0170] The following section continues to describe the other fluid flow structures of the ground electrode 25”.

[0171] refer to Figure 24 and Figures 25A to 25FOutside the reaction zone 2500”, the ground electrode 20” also includes a plurality of through holes that serve as part of the fluid supply channel of the ozone generating unit 2”, such as, for example, a first air inlet through hole 282” as part of the air inlet channel, a second exhaust through hole 292” as part of the exhaust channel, a first inlet flow hole 262” as part of the inlet flow channel, and a first exhaust flow hole 272” as the exhaust flow channel.

[0172] Unlike the first and second embodiments, reference is made to... Figure 24 and Figures 25A to 25F The ground electrode 25” may also include a first air passage 255” formed inside the one-piece body 250”, which is a vertical passage intersecting with the first air inlet hole. The ground electrode 25” may also include a second air passage 256” formed inside the one-piece body 250”, which is a vertical passage intersecting with the first exhaust hole. The ground electrode 25” may also include a cooling passage 254” formed inside the one-piece body 250”, which includes a plurality of parallel vertical passages formed inside the one-piece body and a transverse connecting structure 2542” at the top and bottom connecting the vertical passages. The first vertical passage among the plurality of parallel vertical passages intersects with the first air inlet hole, and the second vertical passage intersects with the first exhaust hole.

[0173] refer to Figure 24 and Figures 25A to 25F The ground electrode 25” may also include an end (top and bottom) sealing groove 2501” for forming the above-mentioned transverse communication structure, a sealing cover for closing the end sealing groove 2501” at the end, and a pressing plate (not shown) for pressing the sealing cover.

[0174] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and associated alignment and positioning structure as described in the first or second embodiments may not be provided in the third embodiment.

[0175] In addition, several first bolt holes 257 can be formed in the ground electrode 25".

[0176] Unlike the first or second embodiment, in the third embodiment, the through-hole for fluid supply (discharge) is circular.

[0177] Furthermore, one will understand that although the above describes a ground electrode at one end, one can imagine a ground electrode at the other end that is symmetrical.

[0178] The following text is based on references. Figure 24 as well as Figures 26A to 29B The high-voltage discharge component 21 of the ozone generating unit 2" in the third embodiment is described.

[0179] like Figure 24 as well as Figures 26A to 29BAs shown, the high-voltage discharge assembly 21” may include an elastic frame member 210” and a pair of dielectric plates 216” on both sides. In addition, the high-voltage discharge assembly 21” may also include an elastic pad assembly.

[0180] like Figure 24 as well as Figures 26A to 29B As shown, the elastic frame member 210” includes a connector portion 2110”, a terminal held by the connector portion and extending from the top of the connector portion, and a pair of elastic contact pieces 2111” electrically connected to the terminal, the pair of elastic contact pieces electrically contacting the back side of the pair of dielectric plates 216. The connector portion 2110” can be accommodated in a limiting groove 2017” or 2527”.

[0181] The elastic frame member 210” may have a frame structure defining a pressure balance region 2100” located on the back side of the pair of dielectric plates 216”. The elastic frame member also includes a second pressure balance structure, including a V-shaped pressure balance groove 2102” with a pair of openings. The V-shaped pressure balance groove extends beyond the envelope of the dielectric plates 216”, thereby communicating with the diversion groove 2018” outside the dielectric plates to receive the reaction gas from the diversion groove 2018’ of the ground electrode 20 and divert it to the pressure balance region 2100”. The pressure balance region may be a hollow portion 2101 formed in the elastic frame member 210”.

[0182] As shown in the figure, several laterally extending balance channels will be provided in the pressure balance zone 2100”, which are provided by the elastic pad assembly.

[0183] like Figure 24 as well as Figures 26A to 29B As shown, the elastic pad assembly includes an elastic pad 212” and heat-conducting plates 214” located on both sides of the elastic pad”. The heat-conducting plates 214” are preferably bonded to the elastic pad 212”.

[0184] As shown in the figure, the elastic pad assembly 212” is floatingly mounted in the thickness direction into the pressure balance zone 2100” of the elastic frame member 210”. Specifically, the elastic frame member 210” includes a plurality of positioning bosses 2105”. The elastic pad assembly 212” includes a plurality of positioning notches for mounting to the plurality of positioning bosses 2105”. Correspondingly, the elastic pad 212 may have a positioning notch 2125”, and the heat-conducting plate 214 may also have a positioning notch 2145”.

[0185] The elastic pad assembly is floatingly mounted in the thickness direction, such that the elastic pad assembly is spaced apart from the frame structure of the elastic frame member 210”, to form a first gap G1” on the first side of the pressure balance zone 2100” and a second gap G2” on the opposite second side. In addition, gaps may also be formed at the top and bottom of the elastic pad assembly.

[0186] like Figure 24 as well as Figures 26A to 29B As shown, the elastic pad 212” includes a plurality of balancing grooves 2121”, preferably two sets of balancing grooves 2121” located on both sides of the elastic pad. The balancing grooves 2121 have an open first end and a second end. In this embodiment, the open first end and the second end have beveled surfaces. In this embodiment, the plurality of balancing grooves and the corresponding heat-conducting plate 214” form a plurality of balancing channels for balancing gas flow. The number of the plurality of balancing grooves 2121” of the elastic pad 212” corresponds to the number of planar grooves for the reaction of the reactant gas on the ground electrodes 20” and 25”, and at least some of the balancing grooves have a shape substantially the same as the corresponding planar grooves.

[0187] like Figure 24 as well as Figures 26A to 29B As shown, the elastic pad assembly may also have a notch to allow the elastic contact piece 2111” to pass through. The shape of the balancing groove, except for the notch, is approximately the same as the shape of the corresponding planar groove.

[0188] like Figure 24 as well as Figures 26A to 29B As shown, there are connecting channels 2128 between several balancing grooves 2121” and between elastic protrusions 2122”, and there are gap regions 2123 between the elastic protrusions.

[0189] Similar to the first and second embodiments, dielectric plate 216” has a single-piece body and includes a front side facing the ground electrode and a back side facing away from the ground electrode. The back side of the dielectric plate has a conductor-coated region that is in electrical contact with the resilient contact piece, and the front side has an enamel-coated region facing the reaction region. The dielectric plate 216” also includes an uncoated edge region surrounding the conductor-coated region. Similarly, a surface discharge suppression structure is formed.

[0190] Furthermore, as mentioned above, the elastic pad assembly and the frame structure of the frame member 210” form gaps G1, G2, etc., thereby forming a further surface discharge suppression structure.

[0191] like Figure 24 as well as Figures 26A to 29B As shown, the elastic frame member 210 of the high-voltage discharge assembly 21” may include a second air inlet 283”, a second exhaust 293”, a second inlet flow hole 263”, and a second outlet flow hole 273” located outside the dielectric plate 216”. Figure 24 as well as Figures 26A to 29B As shown, the second air inlet 283”, the second exhaust 293”, the second air inlet 263”, and the second air outlet 273” are formed by sealing rings. These sealing rings can engage the corresponding surrounding grooves of the adjacent ground electrodes of the ground electrode 20”.

[0192] Unlike the first or second embodiments, the elastic frame member in the third embodiment does not constitute part of the thickness of the ozone generating unit; that is, the thickness of the relevant portion is formed by the ground electrode, thereby allowing the high-voltage discharge assembly to be accommodated in the recessed reaction zone. Accordingly, unlike the first or second embodiments, the third embodiment does not have a pad.

[0193] The elastic frame of the high-voltage discharge assembly may also include a second bolt through hole (not shown).

[0194] like Figure 24 as well as Figures 26A to 29B As shown, the elastic frame 210 of the high-voltage discharge assembly 21” may also have a surrounding ridge 2119”, which can be accommodated in the surrounding groove 2019” of the reaction zone to provide a seal.

[0195] Unlike the first or second embodiment, in the third embodiment, the ground electrode and the high-voltage discharge assembly are installed alternately. The installation method can be carried out in a conventional stacking manner, and they can be tightened with a bolt tightening mechanism.

[0196] Similar to the first or second embodiment, in the third embodiment, as... Figure 24 As shown, the first air inlet holes of the local electrodes and the second air inlet holes of each high-voltage discharge component of the installed ozone generating unit 2” are aligned along the stacking direction to form an air inlet channel spanning the local electrodes, and the air inlet channel is configured to be axially aligned with the air inlet pipe of the ozone generating unit. Similarly, the first exhaust holes of the local electrodes and the second exhaust holes of each high-voltage discharge component of the installed ozone generating unit are aligned along the stacking direction to form an exhaust channel spanning the local electrodes, and the exhaust channel is configured to be axially aligned with the exhaust pipe of the ozone generating unit. Similarly, the first flow inlet holes of the local electrodes and the second flow inlet holes of each high-voltage discharge component of the installed ozone generating unit are aligned along the stacking direction to form a flow inlet channel spanning the local electrodes, and the flow inlet channel is configured to be axially aligned with the flow inlet pipe of the ozone generating unit. Similarly, the first drain holes of the local electrodes and the second drain holes of each high-voltage discharge component of the installed ozone generating unit are aligned along the stacking direction to form a drain channel spanning the local electrodes, and the drain channel is configured to be axially aligned with the drain pipe of the ozone generating unit.

[0197] Here, the reacting gas enters the intake channel from the aforementioned intake pipe, then flows into the first gas path of each cross-crossing ground electrode, passes through the intake micro-hole, and enters the planar groove for reaction. The generated gas flows from the exhaust port to the second gas path, then into the exhaust channel, and finally into the exhaust pipe. Thus, the gas supply (exhaust) structure is not directly connected to the planar groove.

[0198] Similarly, the cooling fluid will enter the inlet channel from the aforementioned inlet pipe, then flow into the parallel cooling channels that cross each ground electrode, and then into the outlet pipe after passing through the outlet channel. Thus, the cooling fluid branch pipes will be eliminated, and the cooling fluid supply and discharge will be provided by the inlet and outlet channels that are incorporated into the ozone generating unit.

[0199] Reference Figures 30-33B This describes an ozone generating unit 2”' according to a fourth embodiment of the present invention. In the illustrated embodiment, the ozone generating unit 2”' can be configured as a plate-type ozone generating unit, and it can be modular, and may also be referred to herein as an ozone generating module.

[0200] In the fourth embodiment shown, the ozone generating unit 2”' may include a plurality of stacked ground electrodes, which are plate-type ground electrodes. In the fourth embodiment shown, the ground electrodes may include conventional ground electrodes 20”. In the fourth embodiment shown, the ozone generating unit 2”' may also include a first end cap 22”' located at a first end and a second end cap 23”' located at a second end. In the fourth embodiment shown, the end caps 22”' or 23”' (also referred to as end ground electrodes) may be configured as end ground electrodes, which may be implemented, for example, with reference to the end ground electrode 25”' of the third embodiment.

[0201] The ozone generating unit 2”' may also include a high-voltage discharge assembly 21”' disposed between the ground electrodes.

[0202] Accordingly, the ground electrode 20”' and the high-voltage discharge assembly 21”' (as well as the end ground electrode, adjacent ground electrodes, and the high-voltage discharge assembly between them) can together form a discharge chamber for the discharge reaction. However, unlike the first and second embodiments, in this fourth embodiment, the ozone generating unit 2”' is configured such that the ground electrodes 20”', 22”', or 23”' are alternately arranged with each high-voltage discharge assembly 21”', that is, they do not form a ground electrode pair.

[0203] The ozone generating unit 2”' may also include an inlet pipe 261”', an outlet pipe 271”', an air inlet pipe 281”', and an exhaust pipe 291”' connected to the first end cap 22”'. The inlet pipe 261”', the outlet pipe 271”', the air inlet pipe 281”', and the exhaust pipe 291”' may also define an inlet port 126, an outlet port 127, an air inlet port 128, and an air outlet port 129.

[0204] Reference Figures 30-33B The ground electrode 20”' may include a reaction zone 2000”' formed in both the first surface 201”' and the second surface 202”' of the single-piece body 200”'. The ground electrode 20”' may include a plurality of planar grooves 2010”' and 2020”' located laterally extending in the reaction zone.

[0205] Similarly, each planar groove 2010"' on the first surface 201"' includes a first curve located at the first end 2013"' and a second curve located at the second end 2014"'. Specifically, the first curve can be a first parabolic curve 2015"', and the second curve can be a second parabolic curve 2016"'. Similarly, the ground electrode 20"' may also include an inlet microhole 2011"' and an outlet microhole 2012"' located within the envelope of each planar groove 2010"', with the inlet microhole 2011"' positioned near the first end 2013"' and the outlet microhole 2012"' positioned near the second end 2014"'. The inlet microhole 2011"' is generally located at the focal point of the first parabolic curve. More specifically, the center of the inlet microhole 2011"' may approximately coincide with the focal point of the first parabolic curve. Similarly, the vent 2012”’ is approximately located at the focus of the second parabola. More specifically, the center of the vent 2012”’ can approximately coincide with the focus of the second parabola.

[0206] Similar to the first surface, each planar groove 2020”' on the second surface 202”' includes a first curve located at the first end 2023”' and a second curve located at the second end 2024”'. Specifically, the first curve can be a first parabolic curve 2025”', and the second curve can be a second parabolic curve 2026”'. Similarly, the ground electrode 20”' may also include an inlet micro-hole 2021”' and an outlet micro-hole 2022”' located within the envelope of each planar groove 2020”', with the inlet micro-hole 2021”' positioned near the first end 2023”' and the outlet micro-hole 2022”' positioned near the second end 2024”'. The inlet micro-hole 2021”' is generally located at the focal point of the first parabolic curve. More specifically, the center of the inlet micro-hole 2021”' may approximately coincide with the focal point of the first parabolic curve. Similarly, the vent 2022”’ is approximately located at the focus of the second parabola. More specifically, the center of the vent 2022”’ can approximately coincide with the focus of the second parabola.

[0207] The structure and size of the air intake micro-hole and air intake hole in the fourth embodiment can refer to the first or second embodiment, but the air intake micro-hole and air intake hole of the ground electrode 20”' in the fourth embodiment are provided on both surfaces.

[0208] Unlike the first to third embodiments, the suboptimal embodiment shown in the fourth embodiment is not a thin ground electrode obtained by determining the thickness of the ground electrode based on the constraint of micropores, but a ground electrode of conventional thickness. However, it is conceivable that other features of this embodiment can be combined with other embodiments in a non-contradictory manner, or that this embodiment can be modified to produce a thin ground electrode.

[0209] Reference Figures 30-33BThe reaction zone 2000”' is roughly rectangular. The single-piece body 200”' of the ground electrode 20”' can also form reaction zone surrounding trenches 2019”' and 2029”' that define the reaction zone 2000”' on both the first surface 201”' and the second surface 202”'.

[0210] Reference Figures 30-33B The ground electrode 20”' also includes a first pressure balancing structure. This first pressure balancing structure is in the form of a trench. In the illustrated embodiment, the first pressure balancing structure is formed only on the first surface, but it is conceivable that it could be formed on both surfaces. Specifically, the ground electrode 20”' includes a diversion trench 2018”' located within the reaction zone 2000, symmetrically connected at the first end 2013 to a planar groove 2010”' (intermediate planar groove). The diversion trench 2018”' extends to and only extends to the air inlet micro-hole 2011”' within the planar groove.

[0211] refer to Figure 24 and Figures 26A to 26F Preferably, all planar grooves 2010”' on the first surface are almost closed, for example, except for the diversion groove 2018”'; preferably, all planar grooves 2020”' on the second surface are closed.

[0212] The following section continues to describe the other fluid flow structures of the ground electrode 20”’.

[0213] Reference Figures 30-33B Outside the reaction zone 2000”’, the ground electrode 20”’ also includes a plurality of through holes that serve as part of the fluid supply channel for the ozone generating unit 2”’, such as, for example, a first air inlet through hole 282”’ as part of the air inlet channel, a second exhaust through hole 292”’ as part of the exhaust channel, a first inlet flow hole 262”’ as part of the inlet flow channel, and a first exhaust flow hole 272”’ as the exhaust flow channel.

[0214] Similar to the third embodiment, in conjunction with the reference Figures 30-33B The ground electrode 20”' may also include a first air passage 205”' formed inside the one-piece body 200”', which is a vertical passage intersecting with the first air inlet hole. The ground electrode 20”' may also include a second air passage 206”' formed inside the one-piece body 200”', which is a vertical passage intersecting with the first exhaust hole. The ground electrode 20”' may also include a cooling passage 204”' formed inside the one-piece body 200”', which includes a plurality of parallel vertical passages formed inside the one-piece body and a transverse connecting structure 2042”' connecting the vertical passages at the top and bottom. The first vertical passage among the plurality of parallel vertical passages intersects with the first air inlet hole, and the second vertical passage intersects with the first exhaust hole.

[0215] However, unlike the third embodiment, in conjunction with the reference... Figures 30-33B In the fourth embodiment, the connecting structure is located on the surface of the monolithic body (such as the first surface), thereby the flow channel in the fourth embodiment can be conventionally sealed with screws.

[0216] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and associated alignment and positioning structure as described in the first or second embodiments may not be provided in the fourth embodiment.

[0217] In addition, several first bolt holes 207”’ can be formed in the ground electrode 20”’.

[0218] The first end cap (end ground electrode) 22”' can be formed similarly to the ground electrode 20”', but the difference is that the first surface 221”' of the ground electrode 22”' does not have a reaction zone and related features.

[0219] Reference Figures 30-33B The first end cap 22”' may include a reaction zone 2200”' formed in the second surface 222”' of the one-piece body 220”'. The ground electrode 22”' may include a plurality of planar grooves 2220”' located laterally extending in the reaction zone.

[0220] The planar grooves 2220" on the second surface 222"' include a first curve located at the first end 2223"' and a second curve located at the second end 2224"'. Specifically, the first curve can be a first parabolic curve 2225"', and the second curve can be a second parabolic curve 2226"'. Similarly, the first end cap 22"' may also include an inlet micro-hole 2221"' and an outlet micro-hole 2222"' located within the envelope of each planar groove 2220"', with the inlet micro-hole 2221"' positioned near the first end 2223"' and the outlet micro-hole 2222"' positioned near the second end 2224"'. The inlet micro-hole 2221"' is generally located at the focal point of the first parabolic curve. More specifically, the center of the inlet micro-hole 2221"' may approximately coincide with the focal point of the first parabolic curve. Similarly, the vent 2222”’ is approximately located at the focus of the second parabola. More specifically, the center of the vent 2222”’ can approximately coincide with the focus of the second parabola.

[0221] The structure and size of the air inlet micro-hole and air inlet hole of the first end cap 22”' can be referenced to the ground electrode 20”', but the air inlet micro-hole and air inlet hole of the first end cap 22”' in the fourth embodiment are provided in the second surface.

[0222] Reference Figures 30-33BThe reaction zone 2200”' is roughly rectangular, and the one-piece body 220”' of the first end cap 22”' can also form a reaction zone surrounding groove 2229”' that defines the reaction zone 2200”' on the second surface 222”'.

[0223] Reference Figures 30-33B Similar to the ground electrode 20”', the first end cap 22”' also includes a first pressure balancing structure. This first pressure balancing structure is in the form of a groove. Specifically, the first end cap 22”' includes a diversion groove 2218”' located within the reaction zone 2200, symmetrically connected to a planar groove 2210”' (intermediate planar groove) at the first end 2213”'. This diversion groove 2218”' extends to and only extends to the air inlet micro-hole 2211”' within the planar groove.

[0224] Reference Figures 30-33B Preferably, all planar grooves 2520”' on the second surface are closed except for the aforementioned diversion grooves 2018”'.

[0225] The following section continues to describe the other fluid flow structures of the first end cap 22”'.

[0226] Reference Figures 30-33B Outside the reaction zone 2200”', the ground electrode 22”' and the first end cap 22”' also include a plurality of through holes that serve as part of the fluid supply channel for the ozone generating unit 2”', such as, for example, a first air inlet through hole 282”' as part of the air inlet channel, a second exhaust through hole 292”' as part of the exhaust channel, a first inlet flow hole 262”' as part of the inlet flow channel, and a first exhaust flow hole 272”' as the exhaust flow channel.

[0227] Similar to the third embodiment, the first end cap 22”' may further include a first air passage 225”' formed inside the one-piece body 220”', which is a vertical passage intersecting with the first air inlet hole. The first end cap 22”' may further include a second air passage 226”' formed inside the one-piece body 220”', which is a vertical passage intersecting with the first exhaust hole. The first end cap 22”' may further include a cooling passage 224”' formed inside the one-piece body 220”', which includes a plurality of parallel vertical passages formed inside the one-piece body and a transverse connecting structure 2242”' connecting the vertical passages at the top and bottom. The first vertical passage among the plurality of parallel vertical passages intersects with the first air inlet hole, and the second vertical passage intersects with the first exhaust hole.

[0228] Similar to ground electrode 20”', in conjunction with reference Figures 30-33B In the fourth embodiment, the connecting structure is located on the surface of the monolithic body (such as the first surface), thereby the flow channel in the fourth embodiment can be conventionally sealed with screws.

[0229] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and associated alignment and positioning structure as described in the first or second embodiments may not be provided in the fourth embodiment.

[0230] In addition, several first bolt holes 227”’ can be formed in the first end cap 22”’.

[0231] Unlike the first or second embodiment, in the fourth embodiment, the through-hole for fluid supply (discharge) is circular.

[0232] Furthermore, one will understand that although the above describes a ground electrode at one end, one can imagine a ground electrode at the other end that is symmetrical.

[0233] The following text is based on references. Figures 30-33B The high-voltage discharge component 21”' of the ozone generating unit 2”' of the fourth embodiment is described.

[0234] like Figures 30-33B As shown, the high-voltage discharge assembly 21”' may include an elastic frame member 210”' and a pair of dielectric plates 216”' on both sides. In addition, the high-voltage discharge assembly 21”' may also include an elastic pad assembly.

[0235] The resilient frame member 210”' includes a connector, a terminal held by the connector and extending from the top of the connector, and a pair of resilient contact pieces electrically connected to the terminal, the pair of resilient contact pieces electrically contacting the back side of the pair of dielectric plates 216”'. The connector can be accommodated in a limiting groove.

[0236] The resilient frame member 210”' may have a frame structure defining a pressure balancing zone located on the back side of the pair of dielectric plates 216”'. Similar to the third embodiment, the resilient frame member also includes a second pressure balancing structure, including a pressure balancing groove having an opening. The pressure balancing groove extends beyond the envelope of the dielectric plate 216”', thereby communicating with a diversion groove outside the dielectric plate to receive reactant gas from the diversion groove of the ground electrode and divert it to the pressure balancing zone, which may be a hollow portion formed in the resilient frame member. A plurality of laterally extending balancing channels, provided by the resilient pad assembly, will be provided in the pressure balancing zone.

[0237] like Figures 30-33BAs shown, the elastic pad assembly includes an elastic pad 212”' and heat-conducting plates 214”' located on both sides of the elastic pad. The heat-conducting plates 214”' are preferably bonded to the elastic pad 212”'. The elastic pad assembly 212”' is floatingly mounted in the thickness direction within the pressure balance zone of the elastic frame member 210”'. Specifically, the elastic frame member 210”' includes a plurality of positioning bosses (not shown). The elastic pad assembly 212”' includes a plurality of positioning notches (not shown) for mounting to the plurality of positioning bosses.

[0238] The elastic pad assembly is floatingly mounted in the thickness direction, such that the elastic pad assembly is spaced apart from the frame structure of the elastic frame member 210”', to form a first gap on the first side of the pressure balance zone 2100”' and a second gap on the opposite second side. In addition, gaps may also be formed at the top and bottom of the elastic pad assembly.

[0239] like Figures 30-33B As shown, the elastic pad 212”' includes a plurality of balancing grooves, preferably two sets of balancing grooves located on both sides of the elastic pad. The balancing grooves have an open first end and a second end. In this embodiment, the open first end and the second end have beveled surfaces. In this embodiment, the plurality of balancing grooves, together with the corresponding heat-conducting plate 214”', form a plurality of balancing channels for balancing gas flow. The number of the plurality of balancing grooves of the elastic pad 212”' corresponds to the number of planar grooves for the reaction gas of the ground electrodes 20”' and 22”', and at least some of the balancing grooves have a shape substantially the same as the corresponding planar grooves.

[0240] like Figures 30-33B As shown, the elastic pad assembly may also have a notch to allow for the elastic contact piece. The shape of the balancing groove, except for the notch, is substantially the same as the shape of the corresponding planar groove.

[0241] like Figures 30-33B As shown, there are connecting channels 2128”' between several balancing grooves 2121”' and elastic protrusions 2122”', and there are gap regions 2123”' between the elastic protrusions.

[0242] Similar to the first, second, and third embodiments, the dielectric plate 216”' has a surface discharge suppression structure. Furthermore, as previously described, the elastic pad assembly forms a gap with the frame structure of the frame member 210”', thereby creating a further surface discharge suppression structure.

[0243] As Figures 30-33B As shown, the elastic frame 210"' of the high-voltage discharge assembly 21"' may include a second inlet port, a second outlet port, a second inlet flow port, and a second outlet flow port located outside the dielectric plate 216"', which are formed by sealing rings. These sealing rings can engage the corresponding surrounding grooves of adjacent ground electrodes of the ground electrode.

[0244] Similar to the third embodiment, in the fourth embodiment, the elastic frame does not constitute part of the thickness of the ozone generating unit; that is, the thickness of the relevant portion is formed by the ground electrode, thereby allowing the high-voltage discharge assembly to be accommodated in the recessed reaction zone. Accordingly, unlike the first or second embodiments, the fourth embodiment does not have a pad.

[0245] The elastic frame of the high-voltage discharge assembly may also include a second bolt through hole (not shown).

[0246] The elastic frame 210”’ of the high-voltage discharge assembly 21”’ may also have a surrounding ridge that can be accommodated in a surrounding groove of the reaction zone to provide a seal.

[0247] Similar to the third embodiment, the ground electrode and high-voltage discharge assembly in the fourth embodiment are installed alternately. The installation method can be carried out in a conventional stacking manner, and they can be tightened by the bolt tightening mechanism 24”’.

[0248] The fluid supply (discharge) structure and distribution structure of the fourth embodiment are similar to those of the third embodiment, and will not be described in detail here.

[0249] As mentioned earlier, especially the reference Figure 1F and Figure 1G The plate-type ozone generating unit 2 of the ozone generator 10 can be connected to electrical components via a terminal block (or terminal block).

[0250] As previously described, the ozone generating unit 2 may include a plurality of stacked ground electrodes and one or more high-voltage discharge components disposed between the plurality of stacked ground electrodes. Accordingly, one or more high-voltage discharge components may be electrically connected to a high-voltage terminal block 3 (or a high-voltage terminal), and the ground electrodes may be electrically connected to a second busbar 31, 31” (or a second terminal). Not shown in the figure, the high-voltage terminal block 3 (or high-voltage terminal) may include or be connected to one or more parallel high-voltage fuses electrically connected to the plurality of high-voltage discharge devices. The above-mentioned electrical connection is achieved, for example, through a connector (not shown).

[0251] According to embodiments of the present invention, the high-voltage safety device included in an ozone generator, such as an ozone generating unit, may be a high-voltage safety device specifically designed for ozone generators or generating units.

[0252] Accordingly, the second bus 31 can be connected to the ground terminal, which is fixed to the ground electrode 20, for example, by means of screws.

[0253] Since these are not the main focus, the specific structures of high-voltage terminal blocks, high-voltage fuse devices, and second busbars will not be described in detail here.

[0254] The following describes multiple embodiments of the present invention in an overview form.

[0275] Example 1.16: An ozone generator comprising at least one ozone generating unit according to Example 1.15.

[0276] The first set of embodiments involves Figures 1A to 33B Furthermore, it involves a novel ground electrode structure.

[0277] In some techniques known to the inventors, ozone gas generation has been achieved by using a planar groove as a reaction space.

[0278] In a further technique known to the inventors based on planar grooves, it is "desired" to provide the largest possible flow rate of reactant gas in the planar microgroove in order to provide more reactant gas and a higher flow rate of generated gas in the planar microgroove. For this purpose, open ends are formed at both ends of the planar groove, and elongated gas cavities are formed in the recessed areas of the stacked ground electrodes by forming elongated holes or elongated grooves in the recessed areas.

[0279] In another known technique based on planar grooves, inlet and outlet holes are formed through the planar grooves of the paired ground electrodes. Based on the "desire" to increase the flow rate of the reactant gas, this technique employs multiple inlet and outlet holes penetrating the ground electrode body, and recesses formed at the locations of the inlet and outlet holes that further descend from the planar grooves as a smooth diffusion structure.

[0280] However, the inventors have discovered that by significantly reducing the size of the air inlet hole in the connected planar groove to an air inlet micro-hole (the outlet hole size can have a higher margin) and allowing the air inlet micro-hole to be close to the curved end, the ozone reaction efficiency can be significantly improved, resulting in a significantly higher output per unit volume (per unit weight) for the ozone generating unit. Compared with the two aforementioned technologies based on planar grooves, the air inlet micro-hole and its structure combined with the curved end in the embodiments of the present invention intentionally reduce the size of the inlet, which to some extent violates the intuition of maximizing the inlet to increase the flow rate of the reactant gas and thus improve the gas production efficiency; moreover, it also eliminates the need for a specially designed diffusion structure, achieving an unexpected effect. Correspondingly, the present invention embodiment 1.1 further improves the gas production efficiency by combining the outlet hole with the curved end, but the inventors realized that the design of the outlet hole size can have a higher margin (as described in embodiment 1.5), rather than having to be reduced to a micro-hole.

[0281] Furthermore, and even more surprisingly, embodiments 1.2 and 1.3 of the present invention, by using a parabolic curve, especially by setting the inlet micro-hole (and preferably the outlet hole as well) at the focal point of the parabola, particularly coinciding with the focal point, can better improve gas production efficiency by providing a smooth gas flow along the curve.

[0282] Furthermore, embodiments 1.4 and 1.5 of the present invention can further improve the flow distribution of the reactant gas by making the curve end partially or almost entirely closed, thereby further improving the gas production efficiency.

[0283] Furthermore, the structure of the inlet micropores (and outlet pores) combined with the curved end adopted in the embodiments of the present invention eliminates the need for the reaction zone to be a recessed area or to be formed in a recessed area. This enables the compact structure of the ozone generating unit and its discharge chamber, and also makes the thin ground electrode possible, as described in the 8th group of embodiments.

[0284] Furthermore, the air inlet micropores described in the embodiments of the present invention also allow the ground electrode itself to form an efficient and compact reactive gas distribution structure and a cold zone fluid distribution structure and associated structure (as described in Examples 1.9 to 1.14), and may also form advantageous inventions by combining the air inlet micropores with these structures, such as the fluid distribution structures and related sealing and positioning structures described in the 5th, 6th, 7th and 9th sets of embodiments.

[0285] Furthermore, the air intake micropore structure described in the embodiments of this application enables novel discharge chamber-related components, structures, or parts, such as the ground electrode, high-voltage discharge components, and related pressure balance structures, thermal balance structures, and surface discharge suppression structures described in the second, third, and fourth sets of embodiments.

[0287] The following describes a second set of embodiments of this application, which includes embodiments 2.1-2.13.

[0288] Example 2.1: A ground electrode includes a single-piece body. The ground electrode further includes a reaction zone formed in at least one of the first and second surfaces of the single-piece body and a plurality of planar grooves extending laterally in the reaction zone. Each planar groove includes a first end and a second end. The ground electrode also includes an inlet micro-hole disposed near the first end and an outlet structure disposed near the second end. The single-piece body further forms a first gas flow channel and a cooling flow channel communicating with the inlet micro-hole. The ground electrode further includes a first pressure balancing structure. The first pressure balancing structure includes a diversion trench connecting, preferably symmetrically connecting, one or more planar grooves at the first end.

[0300] Example 2.12: According to Example 2.10 or Example 2.11, the high-voltage discharge assembly further includes an elastic pad assembly that is floatingly mounted to the elastic frame member in the thickness direction. The elastic pad assembly includes an elastic pad and heat-conducting plates located on both sides of the elastic pad. The elastic pad includes a plurality of balancing grooves, and the plurality of balancing grooves and the corresponding heat-conducting plates form the plurality of balancing channels.

[0301] Example 2.13: An ozone generating unit includes a plurality of stacked ground electrodes and at least one high-voltage discharge component located between the plurality of stacked ground electrodes, wherein the ground electrodes are ground electrodes according to any one of Examples 2.1 to 2.5 and / or the high-voltage discharge component is a high-voltage discharge component according to any one of Examples 2.6 to 2.12.

[0302] Example 2.14: An ozone generating unit, comprising:

[0303] Multiple stacked ground electrodes, each ground electrode comprising a single-piece body, the ground electrode further comprising a reaction zone formed within at least one of the first and second surfaces of the single-piece body and a plurality of laterally extending planar grooves located in the reaction zone, each planar groove comprising a first end and a second end, the ground electrode further comprising an inlet micro-hole disposed near the first end and an outlet micro-hole disposed near the second end, the single-piece body further comprising a first air passage communicating with the inlet micro-hole, a second air passage communicating with the outlet micro-hole, and a cooling passage, wherein the ground electrode further comprises a first pressure balancing structure, the first pressure balancing structure comprising a diversion trench connecting, preferably symmetrically connecting, one or more planar grooves at the first end, the diversion trench extending at least partially beyond the dielectric plate envelope of the high-voltage discharge assembly; and

[0304] At least one high-voltage discharge assembly is located between the plurality of stacked ground electrodes. Each high-voltage discharge assembly includes an elastic frame member and a pair of dielectric plates on two side faces. The elastic frame member includes a connector, a terminal held by the connector and extending from the top of the connector, and a pair of elastic contact pieces electrically connected to the terminal. The pair of elastic contact pieces electrically contact the back side of the pair of dielectric plates. The elastic frame member has a frame structure defining a pressure balance zone located on the back side of the pair of dielectric plates. The elastic frame member also includes a second pressure balance structure, which includes one or more pressure balance grooves disposed near the air inlet end of the ground electrode. The pressure balance grooves have at least one, preferably at least one pair, more preferably symmetrically arranged openings on a first side of the pressure balance zone near the air inlet end. The pressure balance grooves extend beyond the envelope of the dielectric plates and engage with the diversion grooves.

[0305] Example 2.15: An ozone generator comprising at least one ozone generating unit according to Example 2.13 or Example 2.14.

[0306] The second set of embodiments involves Figures 1A to 33B Furthermore, it involves the pressure tank balance structure of the discharge chamber of the ozone generation unit and its related characteristics.

[0307] In related technologies based on planar grooves, in order to improve gas production efficiency, it may be considered to optimize the fluid flow in the ground electrode from the reactive gas supply end to the generated gas outlet end, especially the planar groove and / or the fluid flow into / out of the planar groove.

[0308] However, in the second set of embodiments of the present invention (or a combination of this set of embodiments with other embodiments), a structure is intentionally provided to divert the reactant gas from the planar groove based on the inlet microporous structure. This structure diverts the remaining gas from the planar groove to the back side of the dielectric plate of the high-voltage discharge assembly, thereby providing a balanced gas flow effect on both sides of the dielectric plate, which surprisingly improves the gas production efficiency. Moreover, it can be combined with other embodiments, features, and components to obtain other excellent effects (such as in combination with the third set of embodiments, etc.). Here, the inventors have actually further improved the gas production efficiency by seemingly "disadvantagingly" diverting (reducing) the reactant gas used for the reaction.

[0309] Furthermore, in the second embodiment of the present invention, the flow direction of the pressure balancing structure (such as a flow-diverting structure) in the planar groove is opposite to the conventional gas flow direction from the first end to the second end. However, the pressure balancing structure (such as a flow-diverting structure) in the second embodiment of the present invention can be achieved by combining an inlet micropore structure, and can be better achieved, for example, by combining a curve, especially a parabolic curve, at the first end (as in Embodiment 2.4). In addition, the inventors have carefully selected that the flow-diverting structure is only provided at the first end near the inlet micropore, and not at the second end near the outlet, and preferably only at the flow-diverting groove, which is beneficial for achieving the optimized distribution in the planar groove as described in the first embodiment, and also beneficial for achieving the desired flow-diverted reactive gas for pressure balancing in the second embodiment.

[0310] Furthermore, embodiments 2.10 to 2.12 of the present invention (or embodiments of the second group combined with embodiments of the third group) also propose that the pressure balancing structure further includes forming a pressure balancing channel on the back side of the dielectric plate, providing a further optimized pressure balancing effect, thereby further optimizing the flow of reactant gas in the discharge chamber of the ozone generating unit, thereby further improving the gas production efficiency; in addition, it may also bring other further effects (as described below). Even further, by setting two sets of pressure balancing channels and combining the spacing between the pressure balancing channels and the frame member (pressure balancing groove opening), the flow of reactant gas in the discharge chamber is further optimized by improving the pressure balance between the groups; in addition, the gap thus set may also bring further effects (as described below).

[0313] Example 3.1: An elastic pad assembly for a high-voltage discharge component of an ozone generator, comprising an elastic pad and a pair of heat-conducting plates fixed, preferably bonded, to both sides of the elastic pad. The elastic pad includes a plurality of balancing grooves, preferably two sets of balancing grooves located on both sides of the elastic pad.

[0336] The following describes a fourth set of embodiments of this application, which includes embodiments 4.1-4.10.

[0337] Example 4.1: A high-voltage discharge assembly includes an elastic frame, an elastic pad assembly, and a pair of dielectric plates disposed on both sides.

[0338] The elastic frame member includes a connector, a terminal held by the connector and extending from the top of the connector, and a pair of elastic contact pieces electrically connected to the terminal.

[0339] The elastic pad assembly includes an elastic pad and heat-conducting plates located on both sides of the elastic pad;

[0340] Each dielectric plate includes a front side facing the ground electrode and a back side facing away from the ground electrode.

The uncoated edge area is configured such that the conductor-coated area is spaced apart from the frame structure.

[0341] The heat-conducting plate substantially covers the conductor coating area so that the conductor coating area is spaced apart from the elastic pad.

[0342] Example 4.2: According to the high-voltage discharge assembly of Example 4.1, the elastic pad assembly is floatingly mounted to the elastic frame member in a manner that is spaced apart on at least one side, preferably around the perimeter, so as to form a gap on at least one side, preferably around the perimeter, to suppress surface discharge of the conductor coating area.

[0343] Example 4.3: According to the high-voltage discharge assembly of Example 4.2, the elastic frame member includes a plurality of positioning bosses, and the elastic pad assembly includes a plurality of positioning notches for mounting to the plurality of positioning bosses. Preferably, the positioning bosses are vulcanized.

[0344] Example 4.4: In the high-voltage discharge assembly according to Example 4.2 or Example 4.3, the width of the gap is in the range of 1.5mm to 4mm, preferably in the range of 2mm to 3mm.

[0345] Example 4.5: In the high-voltage discharge assembly according to any one of Examples 4.1 to 4.4, the width of the uncoated edge region is in the range of 2 mm to 6 mm, preferably in the range of 3 mm to 5 mm.

[0346] Example 4.6: A high-voltage discharge assembly includes an elastic frame, an elastic pad assembly, and a pair of dielectric plates disposed on both sides.

[0347] The elastic frame member includes a connector, a terminal held by the connector and extending from the top of the connector, and a pair of elastic contact pieces electrically connected to the terminal. The elastic frame member has a frame structure that defines a hollow portion, in which the elastic pad assembly is located.

[0348] The elastic pad assembly includes an elastic pad and heat-conducting plates located on both sides of the elastic pad;

[0349] Each dielectric plate includes a front side facing the ground electrode and a back side facing away from the ground electrode, and each dielectric plate has a conductor coating area on the back side that is in electrical contact with the elastic contact piece.

[0350] The heat-conducting plate substantially covers the conductor coating area so that the conductor coating area is spaced apart from the elastic pad;

[0351] The elastic pad assembly is floatingly mounted to the elastic frame member in a manner that is spaced apart on at least one side, preferably around the perimeter, to form a gap on at least one side, preferably around the perimeter, to suppress surface discharge of the conductor coating area.

[0352] Example 4.7: According to the high-voltage discharge assembly of Example 4.6, the elastic frame member includes a plurality of positioning bosses, and the elastic pad assembly includes a plurality of positioning notches for mounting to the plurality of positioning bosses. Preferably, the positioning bosses are vulcanized.

[0353] Example 4.8: In the high-voltage discharge assembly according to Example 4.6 or Example 4.7, the width of the gap is in the range of 1.5mm to 4mm, preferably in the range of 2mm to 3mm.

[0354] Example 4.9: An ozone generating unit includes a plurality of stacked ground electrodes and at least one high-voltage discharge component located between the plurality of stacked ground electrodes, wherein the high-voltage discharge component is a high-voltage discharge component according to any one of Examples 4.1 to 4.8.

[0356] The fourth set of embodiments involves Figures 1A to 33B Furthermore, it involves the surface discharge suppression structure of the discharge chamber of the ozone generation unit.

[0357] In plate-type ozone generators, suppressing surface discharge (on the dielectric plate) is a long-standing and desirable problem. To explain rather than limit this, ozone generators typically utilize discharge to produce low-temperature plasma gas for ozone generation. This discharge occurs between the dielectric plate and the ground electrode, and inevitably, other discharges occur along the sides of the dielectric plate, which can sometimes be detrimental. For example, in plate-type ozone generators, especially in the high-voltage discharge assembly within the discharge chamber, elastic (bulk) materials or non-rigid / metallic materials are often used. These detrimental surface discharges can cause aging, carbonization, or even ignition of these materials, adversely affecting the continuous operating time and even the lifespan of the ozone generator. Furthermore, certain detrimental surface discharges can also lead to a decrease in gas production efficiency.

[0358] In the known related technologies of plate ozone generators, it is proposed to form an excessive rounded portion at the corner of the rigid electrode to slow down the accumulation of surface discharge at the corner where surface discharge is most likely to accumulate, which would lead to aging of the non-metallic material of the high-voltage discharge unit or adversely affect the gas production rate.

[0359] In contrast, in the fourth embodiment of the present invention, by forming a surface discharge suppression means on the back side of the dielectric plate, possible surface discharges on the back side are comprehensively suppressed, not just at the corners, thereby improving the continuous operating time and lifespan of the ozone generating unit and avoiding the adverse effects of unwanted surface discharges on gas production efficiency. This is achieved, for example, by an uncoated edge area on the back side of the dielectric plate spaced apart from the frame structure (combined with a conductive plate covering an elastic pad) as described in Embodiment 4.1, or by a floating and gap-mounted elastic pad assembly relative to the elastic frame member as described in Embodiment 4.5 (combined with a heat-conducting plate substantially separating the conductor coating area and the elastic pad), or by a combination of both and / or further combinations of other features.

[0424] Preferably, the alignment and positioning structure on the second surface is located at the four corners outside the reaction zone.

[0425] Example 7.5: In an ozone generating unit according to any one of Examples 7.1 to 7.4, at least a portion of the rigid pads and corresponding pad holes are circular and / or at least a portion of the rigid pads have thick portions at both ends and thin portions in the middle, and the corresponding pad holes have through portions at both ends and thinned portions in the middle.

[0426] Example 7.6: According to one of Examples 7.1 to 7.5, the ozone generating unit, the first end cap is configured to achieve self-alignment by means of the weight of the first end cap, preferably, the weight of the first end cap is more than 2 times, preferably more than 5 times, of the ground electrode.

[0427] Example 7.7: An ozone generating unit according to one of Examples 7.1 to 7.6, wherein the bolt tightening mechanism includes a thread formed in a bolt hole of the second end cap and a bolt capable of being tightened to the thread.

[0428] Example 7.8: An ozone generator comprising an ozone generating unit according to any one of Examples 7.1 to 7.7.

[0429] Example 7.9: An installation method for an ozone generating unit, wherein the ozone generating unit is an ozone generating unit according to any one of Examples 7.1 to 7.7;

[0430] The installation method includes:

[0431] The ground electrode and the high-voltage discharge assembly are stacked on a second end cap that is placed in a plane, wherein the ground electrodes that are in contact with each other and the adjacent high-voltage discharge assemblies are pre-aligned by means of the alignment and positioning structure during stacking.

[0432] The first end cap is pressed firmly onto the stacked ground electrode and high-voltage discharge assembly to ensure precise self-alignment of the pre-positioned ground electrode and high-voltage discharge assembly; and

[0433] The bolt tightening mechanism passes through the bolt holes of the second end cap, ground electrode, high-voltage discharge assembly, and first end cap to tighten and fix the stacked second end cap, ground electrode, high-voltage discharge assembly, and first end cap.

[0434] The rigid pad maintains the compression thickness of the high-voltage discharge assembly during both the pressing and fixing of the first end cap.

[0435] Example 7.10: According to the installation method described in Example 7.9, the ozone generating unit is the ozone generating unit described in Example 7.7;

[0436] The tightening and fixing step includes: tightening the bolts onto the threads of the bolt holes of the second end cap.

[0437] The 7th set of embodiments involves Figures 1A to 23 Furthermore, it relates to a novel alignment and positioning structure for ozone generating units, particularly an alignment and positioning structure based on a combination of a sealing structure and a rigid pad.

[0438] In the known technology of plate-type ozone generators, when installing plate-type ozone generating units (modules), there may be a problem of inaccurate alignment between adjacent ground electrodes when there are many layers in a group. To address this, in these ozone generating units, the high-voltage discharge device, made of elastic material, is itself housed in the recessed area of ​​the plate-type ground electrode, thus requiring only alignment of the plate-type ground electrode. However, even with a large number of layers in a group, the problem of misalignment of the plate-type ground electrodes may still exist. In this case, it may be necessary to use tools such as a rubber mallet to tap the corresponding parts of the ground electrode to facilitate alignment.

[0439] In some embodiments of the present invention, it is desirable to provide a high-voltage discharge unit that constitutes a portion of the thickness of the ozone generating unit in order to obtain other design benefits, such as eliminating the recessed area to obtain a thin ground electrode. However, this further increases the difficulty of alignment when ozone generating units are stacked in a group.

[0440] In the seventh embodiment of the present invention, for example, through the sealing structure with alignment and positioning capability located on both sides of the ground electrode as described in Embodiment 7.1, pre-alignment between ground electrodes and between ground electrodes and high-voltage discharge components (frame members) is achieved when stacked in groups. Furthermore, self-alignment between ground electrodes and between ground electrodes and high-voltage discharge components (frame members) is achieved by combining end cap pressure, for example by the gravity of the end cap (as in Embodiment 7.6). Moreover, during stacking, pressing and subsequent bolt tightening, the thickness of the high-voltage discharge components (frame members) is maintained by a number of rigid pads located outside the reaction zone of the frame members.

[0441] In a preferred embodiment 7.7 and 7.10, the ozone generating units (modules) can be tightened from the top by selecting the thread of the end cap, without needing to expose the bottom surface of the second end cap as in a bolt and nut structure, which might require lifting the group of ozone generating units (modules).

[0456] In ozone-related technologies such as plate ozone generators, although product thinning is one of the goals, it ranks after key indicators such as gas production efficiency, continuous operating time, and service life. Moreover, due to safety redundancy requirements, designers often do not consider it and find it difficult to propose design ideas for thinning the ground electrode.

[0457] However, in this embodiment of the invention, the inventors propose an inlet micro-orifice (with a larger margin in the outlet size or even other outlet structures) that seemingly disadvantageously reduces the flow rate of the reacting gas, which can significantly improve the ozone reaction efficiency, resulting in a significantly higher yield per unit volume (per unit weight) for the ozone generating unit. Based on this, in the eighth embodiment of the invention, the inventors, constrained by the inlet micro-orifice (reduced flow rate), innovatively propose a novel thin-film ground electrode structure for both single-sided (e.g., Example 8.1) and double-sided (e.g., Example 8.5) ground electrode constructions, compared to control ground electrodes which may have a thickness of 2 to 6 times.

[0458] Thus, the eighth embodiment of the present invention achieves a thin ground electrode with significantly reduced thickness while ensuring gas production efficiency. Such ground electrodes, when grouped together, will allow ozone generating units or ozone generators to have significantly higher unit gas production efficiency.

[0459] Group 9 Examples

[0463] Multiple high-voltage discharge components located between the multiple stacked ground electrodes include an elastic frame member and a pair of dielectric plates on both sides. The elastic frame member includes a connector, a terminal held by the connector and extending from the top of the connector, and a pair of elastic contact pieces electrically connected to the terminal, the pair of elastic contact pieces electrically contacting the back side of the pair of dielectric plates.

[0464] Among them, the single-piece body of each electrode includes a first air inlet, a first exhaust, a first inlet flow, and a first outlet flow located outside the reaction zone; the elastic frame of each high-voltage discharge component includes a second air inlet, a second exhaust, a second inlet flow, and a second outlet flow located outside the dielectric plate.

[0466] The first exhaust ports of the local electrodes of the ozone generating unit and the second exhaust ports of each high-voltage discharge component are aligned along the stacking direction to form an exhaust channel spanning the local electrodes, and the exhaust channel is configured to be axially aligned with the exhaust pipe of the ozone generating unit.

[0467] The first inlet holes of each local electrode of the ozone generating unit and the second inlet holes of each high-voltage discharge component are aligned along the stacking direction to form an inlet channel spanning the local electrodes, and the inlet channel is configured to be axially aligned with the inlet pipe of the ozone generating unit.

[0468] The first drain holes of each local electrode of the ozone generating unit and the second drain holes of each high-voltage discharge component are aligned along the stacking direction to form a drain channel spanning the local electrodes, and the drain channel is configured to be axially aligned with the drain pipe of the ozone generating unit.

[0470] Example 9.3: In the ozone generating unit according to Example 9.1 or Example 9.2, the air inlet pipe, exhaust pipe, inlet pipe, and outlet pipe are connected to the same end of the ozone generating unit.

[0472] The ozone generating unit is configured such that adjacent ground electrodes are attached to each other with their second surfaces to form a ground electrode pair, and the first surfaces of the ground electrode pairs are opposite each other and the high-voltage discharge component is placed between the first surfaces of the adjacent ground electrode pairs.

[0473] Example 9.5: According to the ozone generating unit described in Example 9.4, each electrode has a surrounding groove on its first surface that surrounds a first air inlet hole, a surrounding groove that surrounds a first exhaust hole, a surrounding groove that surrounds a first inlet flow hole, and a surrounding groove that surrounds a first exhaust flow hole. The elastic frame of the high-voltage discharge assembly has a sealing ridge surrounding a second air inlet hole, a sealing ridge surrounding a second exhaust hole, a sealing ridge surrounding a second inlet flow hole, and a sealing ridge surrounding a second exhaust flow hole. Each electrode has a first air passage surrounding groove surrounding a first air passage and an air inlet hole, and a second air passage surrounding a second air passage and an exhaust flow hole on its second surface. The air passage surrounds the groove and the cooling flow surrounds the inlet and outlet passages; thus, the sealing ridge of the frame member of the high-voltage ground electrode placed between adjacent ground electrode pairs seals the corresponding surround groove of the adjacent ground electrode, and the first air passage surround groove of the mating ground electrode pair together accommodates the first air passage surround seal, the second air passage surround groove of the mating ground electrode pair together accommodates the second air passage surround seal, and the cooling flow surround groove of the mating ground electrode pair together accommodates the cooling flow surround seal, thereby circumferentially sealing the inlet passage, the exhaust passage, the inlet passage, and the outlet passage across the ground electrodes.

The frame member of the high-voltage discharge assembly has a sealing ring forming a second air inlet hole, a sealing ring forming a second exhaust hole, a sealing ring forming a second inlet flow hole, and a sealing ring forming a second exhaust flow hole. Thus, the sealing rings of the frame member of the high-voltage ground electrode placed between adjacent ground electrodes seal and engage with the corresponding annular grooves of the adjacent ground electrodes, thereby circumferentially sealing the air inlet channel, the exhaust channel, the inlet flow channel, and the exhaust flow channel spanning the ground electrodes.

[0478] Example 9.10: An ozone generator comprising an ozone generating unit according to any one of Examples 9.1 to 9.9.

[0479] The 9th set of embodiments involves Figures 1A to 33B Furthermore, it involves a novel gas / cold zone fluid supply (exhaust) channel structure for the ozone generating unit.

[0480] In related technologies for plate-type ozone generators, the fluid supply (discharge) structure can be quite space-consuming, thus reducing the number of fluid supply (discharge) pipes is desirable. Furthermore, the inventors are also seeking to improve the impact of fluid supply (discharge) on fluid flow in the reaction zone (planar groove) within related technologies based on planar grooves.

[0481] Therefore, in the ninth embodiment of the present invention, both the gas supply (exhaust) structure and the cooling fluid supply (exhaust) structure are internalized inside the ozone generating unit. This significantly reduces the number of pipes required for the fluid supply (exhaust) structure, i.e., forming several supply (exhaust) channels across the ground electrode instead of the external connection pipes that might otherwise be needed.

[0482] Furthermore, in the ninth embodiment of the present invention, by arranging the gas supply (exhaust) structure inside the ozone generating unit but outside the reaction zone, it is beneficial to achieve improved distribution and flow of the gas (reacting gas or generated gas), especially in the reaction zone. In addition, the ninth embodiment of the present invention can further optimize the gas distribution and flow by incorporating inlet micropores (exhaust pores).

[0483] Furthermore, in the ninth embodiment of the present invention, by placing the cooling flow supply (discharge) structure inside the ozone generating unit and aligning the cooling flow supply (discharge) structure with the cooling flow pipe, the cooling flow pipe that would normally need to be parallel to and span across the ozone generating unit is eliminated, and the number of cooling flow inlet points is significantly reduced, thereby reducing the risk of leakage. Moreover, by placing the cooling flow supply (discharge) structure inside and across the ozone generating unit, cooling flow supply (discharge) can be achieved in each ground electrode (or each pair of ground electrodes), avoiding the situation in some known technologies where the cooling flow needs to flow through several ground electrodes.
