With continued reference to FIGS. 1A-1G , the ozone generator 1 can include a cooling device 131 (e.g., a cooling fan) disposed on the top panel 13.

[0055] It will be appreciated that the ozone generation unit (which can also be referred to as an "ozone generation module") of embodiments of the present application can be adapted not only to the integrated ozone generator as shown in FIGS. 2A-13C , but also to other forms of ozone generators or combinations or arrays of different ozone generators, which fall within the scope of the present application.

[0056] For example, in further embodiments, an ozone generator in the form of a rack can be provided, which can include a rack, a plurality of ozone generation units, a gas distribution system, and a cooling fluid distribution system. In such a rack-form ozone generator, the plurality of ozone generation units can share one or more sets of electrical components.

[0058] With reference to FIGS. 3A-4DThis 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. FIGS. 3A-3C As stated above.

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

[0061] Accordingly, such as FIGS. 2A-2C 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 FIGS. 3A-4D 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] Continue to refer to FIG. 4A 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.

[0065] like FIG. 4C and FIG. 4A As 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.

[0066] As shown in FIG. 4C and FIG. 4A each planar recess 2010 includes a first curve at a first end 2013 and a second curve at a second end 2014. In particular, the first curve 2015 can be a first parabolic curve 2015 and the second curve 2016 can be a second parabolic curve 2016.

[0067] As shown in FIG. 4C and FIG. 4A the ground electrode 20 can further include an air inlet micro-hole 2011 and an air outlet hole 2012 within the envelope of each planar recess 2010, the air inlet micro-hole 2011 being disposed proximate to the first end 2013 and the air outlet hole 2012 being disposed proximate to the second end 2014. In FIG. 4C and FIGS. 2A-13C the air inlet micro-hole 2011 is disposed substantially at the focal point of the first parabolic curve. More particularly, the center of the air inlet micro-hole 2011 can substantially coincide with the focal point of the first parabolic curve. Similarly, the air outlet hole 2012 is disposed substantially at the focal point of the second parabolic curve. More particularly, the center of the air outlet hole 2012 can substantially coincide with the focal point of the second parabolic curve.

[0068] In the embodiments of the present application, the "micro-hole" can be determined according to the size of the ground electrode 20, for example, specifically less than or equal to 2 mm. In the preferred embodiments, the air inlet micro-hole 2011 has a hole diameter of 0.1 mm to 1 mm, preferably 0.2 mm to 0.5 mm, more preferably 0.2 mm to 0.3 mm.

[0069] In the embodiments of the present application, the thickness of the ground electrode can be determined based on the constraint of the micro-hole, thereby obtaining a thin ground electrode. Preferably, in the embodiments shown in FIG. 4A the ratio of the thickness of the one-piece body of the ground electrode to the hole diameter of the air inlet micro-hole 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 one-piece 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 appreciated that the intersection of the two can be taken. In the preferred embodiments shown in the drawings, the air inlet micro-hole can have a thickness of 0.3 mm, and the ratio of the thickness of the one-piece body to the hole diameter of the air inlet micro-hole can be 13.3.

[0070] As described herein, the air outlet hole 2012 can not be limited to be a "micro-hole" and can have a wider hole diameter size. In the preferred embodiments, the ratio of the hole diameter of the air outlet hole 2012 to the air inlet micro-hole 2011 is in the range of 1.5 to 15, preferably in the range of 2 to 10, preferably in the range of 2 to 8.

[0071] AsFIG. 4C and FIG. 4A 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.

[0072] like FIG. 4C and FIG. 4A 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... FIG. 4C and FIGS. 3A-5B As shown, the diversion groove 2018 connects the topmost planar groove 2010 and the bottommost planar groove 2010. (Refer to reference...) FIG. 4A 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.

[0073] Continue to refer to FIG. 4C and FIGS. 4A-4D Preferably, all planar grooves 2010 are "almost" closed, except for the diversion grooves 2018.

[0074] The following section continues to describe other fluid flow structures of the ground electrode 20.

[0075] Continue to refer to FIG. 4B As 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.

[0076] like FIG. 4D and FIG. 4B 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.

[0077] Specifically, such as FIG. 4D and FIG. 4BAs shown, the first gas flow channel 2021 is orthogonal to the first gas inlet hole 282, the second gas flow channel 2022 is orthogonal to the first gas outlet hole 292, the cooling flow channel 2020 is orthogonal to the first flow inlet hole 262 at one end and orthogonal to the first flow outlet hole 272 at the other end, and the gas inlet micro-hole 2011 is in communication with the first gas flow channel 2021 and the corresponding planar groove 2010, and the gas outlet hole 2012 is in communication with the corresponding planar groove 2010 and the second gas flow channel 2022.

[0078] As shown in FIG. 4D and FIG. 4B , the first gas flow channel 2021 of the second surface 202 is in communication with the gas inlet micro-hole 2011 of the first surface 201 through the stepped hole structure 2026, and the aperture of the stepped hole structure 2026 is larger than the aperture of the gas inlet micro-hole 2011. Specifically, the stepped hole structure 2026 is a one-stage stepped hole or a multi-stage stepped hole, and the aperture of the one-stage stepped hole or the first aperture of the multi-stage stepped hole can be substantially equal to the aperture of the gas outlet hole 2012. In FIG. 4D and FIGS. 3A-4D the embodiment shown, the stepped hole structure 2026 is a one-stage stepped hole.

[0079] Thus, as shown in FIG. 4A , the first gas inlet hole 282, the first gas flow channel 2021, the gas inlet micro-hole 2011, the planar groove 2010, the gas outlet hole 2012, the second gas flow channel 2022, and the first gas outlet hole 292 form a gas flow distribution structure in the ground electrode 20 in sequence.

[0080] As shown in FIG. 4C and FIGS. 3A-4D , the ground electrode 20 forms a surrounding groove around the first gas inlet hole 282, a surrounding groove around the first gas outlet hole 292, a surrounding groove around the first flow inlet hole 262, and a surrounding groove around the first flow outlet hole 272 on the first surface 201.

[0081] Similarly, as shown in FIG. 4B , the flow inlet hole 262, the meandering cooling flow channel 2020, and the flow outlet hole 272 form a cooling flow distribution structure in the ground electrode 20 in sequence.

[0082] As shown in FIG. 4D and FIG. 11 in combination with FIG. 12 and FIGS. 2A-2CAs 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.

[0083] In the illustrated embodiment, as FIGS. 3A-3C 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.

[0084] 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.

[0085] These seals can serve as alignment and positioning structures when ozone generating units are grouped together, as further described below.

[0086] In addition, several first bolt holes 207 can be formed in the ground electrode 20.

[0087] The following text is based on references. FIGS. 5A-10B as well as FIGS. 2A-3C This describes the high-voltage discharge component of ozone generation unit 2.

[0088] like FIGS. 3A-3C In the illustrated embodiment, the high-voltage discharge assembly 21 is placed between the first surfaces of adjacent ground electrodes 20.

[0089] like FIGS. 5A-10B as well as FIGS. 4CAs 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.

[0090] like FIGS. 6A-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 ( FIGS. 6A-6D )middle.

[0091] For details, please refer to the following: FIGS. 3A-3C 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.

(Referring to the reference...) FIG. 5B as well as FIGS. 7A-9C and FIGS. 4C The first pressure balancing groove 2103 extends beyond the envelope of the dielectric plate 216, thereby connecting the diversion groove 2018 outside the dielectric plate to receive the reaction gas from the diversion groove 2018 of the ground electrode 20 and divert it to the pressure balancing region 2100, which may be a hollow portion 2101 formed in the elastic frame member 210.

[0092] 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.

[0093] refer to FIGS. 5A-5B 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.

[0094] As shown, the elastic pad assembly 212 is floatingly mounted in the thickness direction to the pressure balancing region 2100 of the elastic frame member 210. Specifically, as shown FIGS. 7A-7C , the elastic frame member 210 includes a plurality of positioning bosses 2105, which are preferably vulcanized. As shown FIGS. 5A-5B and FIGS. 7A-8B , the elastic pad assembly 212 includes a plurality of positioning notches for mounting to the plurality of positioning bosses 2105. Accordingly, the elastic pad 212 can have positioning notches 2125, and the heat conducting plate 214 can also have positioning notches 2145. The body 2140 of the heat conducting plate 214 is of a heat conducting metal material, such as stainless steel, and can be subjected to suitable material treatment.

[0095] As shown FIGS. 4A-4D , 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 a first side and a second gap G2 on an opposite second side of the pressure balancing region 2100. In addition, gaps can also be formed at the top and bottom of the elastic pad assembly.

[0096] Referring to FIGS. 7A-8B , the elastic pad 212 includes a number of balancing grooves 2121, preferably two sets of balancing grooves 2121 located on the two side faces of the elastic pad. The balancing grooves 2121 have open first and second ends. In this embodiment, the open first and second ends have end openings 2126, 2127. In this embodiment, the number of balancing grooves form a number of balancing channels with the corresponding heat conducting plate 214 for balancing the flow of gas. In combination with reference to FIGS. 8A-9C and FIGS. 4A-4D , the number of balancing grooves 2121 of the elastic pad 212 corresponds to the number of planar grooves 2010 of the ground electrode 20 for reaction of the reaction gas, and at least some of the balancing grooves have substantially the same shape as the corresponding planar grooves. In this embodiment, at least some of the balancing grooves have substantially the same planar shape and substantially the same depth as the corresponding planar grooves.

[0097] Referring to FIGS. 7A-8B , the elastic pad assembly can also have notches for giving way to the elastic contact pieces 2111. Accordingly, the elastic pad 212 can have notches 2124, and the heat conducting plate 214 can also have notches 2144. In combination with reference to FIGS. 10A-10B and FIGS. 3A-3C , the balancing grooves have substantially the same shape as the corresponding planar grooves except for the notches.

The dielectric plate 216 has a conductor-coated region 2161 on the back side in electrical contact with the elastic contact tab and an enamel-coated region 2162 on the front side facing the reaction region. The dielectric plate 216 also includes an uncoated edge region 2163 surrounding the conductor-coated region 2161. The conductor-coated region 2161 can be a silver-coated region. See FIG. 10B and FIGS. 5A-6D and FIGS. 5A-6D The uncoated edge region 2163 is configured such that the conductor-coated 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-coated region 2161, thereby forming an electrical creepage structure.

[0099] In addition, as previously described, the elastic pad assembly and the frame structure of the frame member 210 form a gap G1, G2, etc., thereby the gap forms a further electrical creepage structure.

[0100] Referring to FIGS. 5A-6D The elastic frame member 210 of the high-voltage discharge assembly 21 can include a second gas inlet through-hole 283, a second gas outlet through-hole 293, a second fluid inlet through-hole 263, and a second fluid outlet through-hole 273 outside the dielectric plate 216.

These sealing ridges can engage the corresponding surrounding grooves of the ground electrode 20 that engage adjacent ground electrodes.

[0101] These sealing ridges can also serve as alignment positioning structures of the ground electrode 20 and the high-voltage discharge assembly 21.

[0102] Continuing to refer to FIGS. 5A-6D and FIGS. 13A-13B The high-voltage discharge assembly 21 also includes pad block holes 2117, 2118 in the elastic frame member 210 and rigid pad blocks 217, 218 for accommodating in the pad block holes. As shown in FIGS. 5A-6D and FIGS. 5A-6D The rigid pad blocks 1218 on both sides of the elastic frame member 210 have thick portions at both ends and a thin portion in the middle and the corresponding pad block holes 218 have through portions at both ends and a thinned portion in the middle. The rigid pad blocks 217 on the top and bottom of the elastic frame member 210 and the corresponding pad block holes 2117 are circular.

[0103] Referring to FIGS. 2A-13C The elastic frame member 210 of the high-voltage discharge assembly 21 can also include a second bolt through-hole 2116.

[0104] refer to FIGS. 2A-2C 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.

[0105] The following will refer to FIG. 3B 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.

[0106] 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). FIG. 4B 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.

[0107] 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. FIG. 2C and FIG. 2A 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.

[0108] 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 alignment and positioning structure is precisely self-aligned due to the pressing. FIG. 3CAs best shown, the compression 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 2 times, preferably more than 5 times, the weight of the ground electrode 20. It will be appreciated that the first end cap 22 and the second end cap 23 are merely distinguished here, and are not limiting to the specific end cap for compression.

[0109] Subsequently, the bolts can be screwed into the bolt through holes 221 of the second end cap 23, so that the bolts pass through the first end cap 22, the ground electrode 20 and the high voltage discharge assembly 21 to screw into the bolt through holes 221 of the second end cap 23.

[0110] Through the above assembly process, the various components of the ozone generation unit 2 can achieve accurate alignment and sealing, thereby ensuring the performance and stability of the equipment.

[0111] The fluid supply (discharge) of the assembled ozone generator and the fluid distribution in each ground electrode will be described below.

[0112] In combination with reference to FIGS. 14-23 and FIG. 14 , the first gas inlet through holes of each ground electrode and the second gas inlet through holes of each high voltage discharge assembly of the installed ozone generation unit are aligned in the stacking direction to form a gas inlet passage across each ground electrode, and the gas inlet passage is configured to be axially aligned with a gas inlet pipe for the ozone generation unit. Similarly, the first gas outlet through holes of each ground electrode and the second gas outlet through holes of each high voltage discharge assembly of the installed ozone generation unit are aligned in the stacking direction to form a gas outlet passage across each ground electrode, and the gas outlet passage is configured to be axially aligned with a gas outlet pipe for the ozone generation unit. Similarly, the first flow inlet through holes of each ground electrode and the second flow inlet through holes of each high voltage discharge assembly of the installed ozone generation unit are aligned in the stacking direction to form a flow inlet passage across each ground electrode, and the flow inlet passage is configured to be axially aligned with a flow inlet pipe for the ozone generation unit. Similarly, the first flow outlet through holes of each ground electrode and the second flow outlet through holes of each high voltage discharge assembly of the installed ozone generation unit are aligned in the stacking direction to form a flow outlet passage across each ground electrode, and the flow outlet passage is configured to be axially aligned with a flow outlet pipe for the ozone generation unit.

[0113] Here, the reaction gas will enter the gas inlet passage from the above-mentioned gas inlet pipe, then flow into the first gas path flow channel of each ground electrode (ground electrode pair) across the ground electrode, pass through the gas inlet micro-pores and then enter the planar recess for reaction, and the generated gas will flow from the gas outlet hole to the second gas path flow channel and then flow into the gas outlet passage and then enter the gas outlet pipe. Thus, the gas supply (discharge) structure will not directly communicate with the planar recess.

[0114] Similarly, the cooling fluid will enter the inlet flow channel from the inlet flow tube, then flow into the M-shaped cooling flow channel of each cross-over ground electrode (the pair of abutting ground electrodes), and then flow into the outlet flow channel and then into the outlet flow tube. Thus, the cooling fluid branch tube will be omitted, and the cooling fluid supply and discharge will be provided by the inlet and outlet flow channels incorporated into the ozone generation unit.

Unlike the first and second embodiments, however, in this third embodiment the ozone generation unit 2" is configured such that each ground electrode 20", 25" is arranged alternately with each high-voltage discharge assembly 21", i.e., not as a ground electrode pair.

The air inlet micro-hole 2021" is disposed substantially at the focal point of the first parabolic curve. More particularly, the center of the air inlet micro-hole 2021" can substantially coincide with the focal point of the first parabolic curve. Similarly, the air outlet hole 2022" is disposed substantially at the focal point of the second parabolic curve. More particularly, the center of the air outlet hole 2022" can substantially coincide with the focal point of the second parabolic curve.

[0149] The structure and size of the air inlet micro-hole and the air inlet hole of the third embodiment can refer to the first or second embodiment, but the air inlet micro-hole and the air inlet hole of the ground electrode 20" of the third embodiment are disposed in both surfaces.

[0150] In the embodiments of the present application, the thickness of the ground electrode can be determined based on the constraint of the micro-hole, thereby obtaining a thin ground electrode. Preferably, in the embodiments of the present application, the thickness of the ground electrode is less than or equal to 30 mm, preferably less than or equal to 25 mm, more preferably less than or equal to 20 mm, and most preferably less than or equal to 15 mm.

[0152] Referring to FIG. 24 and FIGS. 26A-26F the reaction zone 2000" is substantially rectangular, and the one-piece body 200" of the ground electrode 20" can further form a reaction zone surrounding groove 2019", 2029" on both the first surface 201" and the second surface 202" that defines the reaction zone 2000".

[0153] Referring to FIG. 24 and FIGS. 26A-26FThe ground electrode 20" further comprises a first pressure balancing structure. The first pressure balancing structure is in the form of a groove. In the embodiment shown, the first pressure balancing structure is formed on only the first surface, but it is contemplated that it could be formed on the second surface as well or on both surfaces. In particular, the ground electrode 20" comprises a shunt groove 2018" within the reaction zone 2000 that is symmetrically connected at the first end 2013 to a planar recess 2010" (intermediate planar recess). The shunt groove 2018" extends to and only to the gas inlet micro-holes 2011" in the planar recess.

[0154] With reference to FIG. 24 and FIGS. 26A-26F , preferably all of the planar recesses 2010" on the first surface are nearly closed, e.g., except for the shunt groove 2018"; preferably all of the planar recesses 2020" on the second surface are closed.

[0155] Other fluid flow structures of the ground electrode 20" are described below.

[0156] With reference to FIG. 24 and ​ , in addition to the reaction zone 2000", the ground electrode 20" further comprises a plurality of through-holes that serve as part of the fluid supply channels of the ozone generation unit 2", e.g., first gas inlet through-holes 282" that are part of the gas inlet channel, second gas outlet through-holes 292" that are part of the gas outlet channel, first flow inlet through-holes 262" that are part of the flow inlet channel, and first flow outlet through-holes 272" that are part of the flow outlet channel.

[0157] Unlike the first and second embodiments, with reference to ​ and Figures 26A-26F , the ground electrode 20" can further comprise a first gas path flow channel 205" formed inside the one-piece body 200" that is a vertical flow channel intersecting the first gas inlet through-holes. The ground electrode 20" can further comprise a second gas path flow channel 206" formed inside the one-piece body 200" that is a vertical flow channel intersecting the first gas outlet through-holes.

[0158] With reference to Figure 24 and Figures 26A-26F , the ground electrode 20" can further comprise end portion (top and bottom) sealing grooves 2001" for forming the above-described transverse communication structures, and sealing cover plates for closing the above-described end portion sealing grooves 2001" at the end portions and pressing plates (not shown) for pressing the sealing cover plates.

[0159] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and the associated alignment positioning structure as described in the first or second embodiment can not be provided in the third embodiment.

[0160] In addition, a plurality of first bolt holes 207" can be formed in the ground electrode 20".

[0161] The ground electrode 25" can be formed similar to the ground electrode 20", but differs in that the first surface 251" of the ground electrode 25" is not provided with the reaction zone and the associated features.

[0162] Referring to Figure 24 and Figures 25A-25F , the ground electrode 25" can include a reaction zone 2500" formed in the second surface 252" of the single-piece body 250". The ground electrode 25" can include a plurality of planar grooves 2520" extending laterally in the reaction zone.

[0163] Each planar groove 2520" on the second surface 252" includes a first curve at a first end 2523" and a second curve at a second end 2524". In particular, 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" can also include an air inlet micro-hole 2521" and an air outlet hole 2522" within the envelope of each planar groove 2520", the air inlet micro-hole 2521" being disposed adjacent to the first end 2523" and the air outlet hole 2522" being disposed adjacent to the second end 2524". The air inlet micro-hole 2521" is disposed substantially at the focal point of the first parabolic curve. More particularly, the center of the air inlet micro-hole 2521" can substantially coincide with the focal point of the first parabolic curve. Similarly, the air outlet hole 2522" is disposed substantially at the focal point of the second parabolic curve. More particularly, the center of the air outlet hole 2522" can substantially coincide with the focal point of the second parabolic curve.

[0164] The structure and size of the air inlet micro-hole and the air inlet hole of the ground electrode 25" can refer to the ground electrode 20", but the air inlet micro-hole and the air inlet hole of the ground electrode 25" of the third embodiment are disposed in the second surface.

[0165] In the embodiments of the present application, the thickness of the ground electrode can be determined based on the constraints of the micro-hole, thereby obtaining a thin ground electrode.

[0166] Referring to Figure 24 and Figures 25A-25F , the reaction zone 2500" is substantially rectangular, and the single-piece body 250" of the ground electrode 25" can also form a reaction zone surrounding groove 2529" in the second surface 252" that defines the reaction zone 2500".

[0167] Referring to Figure 24 andFigures 25A-25F Unlike ground electrode 20", ground electrode 25" is not provided with the first pressure balancing structure. However, it is conceivable that the first pressure balancing structure is provided in ground electrode 25".

[0168] Reference is made to Figure 24 and Figures 25A-25F Preferably, all of the planar grooves 2520" on the second surface are closed.

[0169] Further fluid flow structures of ground electrode 25" are described below.

[0170] Reference is made to Figure 24 and Figures 25A-25F In addition to the reaction zone 2500", ground electrode 20" further comprises a plurality of through holes serving as part of the fluid supply channels of ozone generation unit 2", here for example a first gas inlet through hole 282" serving as part of the gas inlet channel, a second gas outlet through hole 292" serving as part of the gas outlet channel, a first flow inlet through hole 262" serving as part of the flow inlet channel, and a first flow outlet through hole 272" serving as part of the flow outlet channel.

[0171] Unlike the first and second embodiments, reference is made to Figure 24 and Figures 25A-25F Ground electrode 25" can further comprise a first gas path flow channel 255" formed inside the one-piece body 250", which is a vertical flow channel intersecting the first gas inlet through hole. Ground electrode 25" can further comprise a second gas path flow channel 256" formed inside the one-piece body 250", which is a vertical flow channel intersecting the first gas outlet through hole. Ground electrode 25" can further comprise a cooling flow channel 254" formed inside the one-piece body 250", which comprises a plurality of parallel vertical flow channels formed inside the one-piece body and a top and bottom end portion transverse communication structure 2542" communicating the vertical flow channels, a first vertical flow channel of the plurality of parallel vertical flow channels intersecting the first flow inlet through hole, and a second vertical flow channel of the plurality of parallel vertical flow channels intersecting the first flow outlet through hole.

[0172] Reference is made to Figure 24 and Figures 26A-29B Ground electrode 25" can further comprise an end portion (top and bottom) sealing groove 2501" for forming the above-mentioned transverse communication structure, and a sealing cover plate for closing the above-mentioned end portion sealing groove 2501" at the end portion, and a pressing plate (not shown) for pressing the sealing cover plate.

[0173] Since the fluid distribution structure is formed inside the one-piece body, in the third embodiment, the annular seal and the associated alignment positioning structure as described in the first or second embodiment can not be provided.

[0174] In addition, a plurality of first bolt holes 257" can be formed in ground electrode 25".

[0175] In the third embodiment, the through hole for fluid supply (discharge) is circular, unlike the first or second embodiments.

[0176] Furthermore, it will be appreciated that, although the ground electrode of one end is described above, the ground electrode of the other end can be symmetrically conceived.

[0177] The third embodiment will be described below in conjunction with the reference Figure 24 and Figures 26A-29B of the high-voltage discharge assembly 21" of the ozone generation unit 2" of the third embodiment.

[0178] As shown in Figure 24 and Figures 26A-29B , the high-voltage discharge assembly 21" can include a resilient frame member 210" and a pair of dielectric plates 216" on two sides thereof. In addition, the high-voltage discharge assembly 21" can further include a resilient pad assembly.

[0179] As shown in Figure 24 and Figures 26A-29B , the resilient frame member 210" includes a joint portion 2110", a terminal held by the joint portion and extending out of the top of the joint portion, and a pair of resilient contact pieces 2111" electrically connecting the terminal, which electrically contact the back side of the pair of dielectric plates 216". The joint portion 2110" can be accommodated in the limiting recess 2017" or 2527".

[0180] The resilient frame member 210" can have a frame structure defining a pressure balancing region 2100" located at the back side of the pair of dielectric plates 216". The resilient frame member further includes a second pressure balancing structure including a V-shaped pressure balancing groove 2102" having a pair of openings. The V-shaped pressure balancing groove extends out of the envelope of the dielectric plates 216" so as to communicate with the shunt groove 2018" outside the dielectric plates to receive the reaction gas from the shunt groove 2018' of the ground electrode 20 and shunt to the pressure balancing region 2100", which can be a hollow portion 2101" formed in the resilient frame member 210".

[0181] As shown, a plurality of laterally extending balancing channels will be provided in the pressure balancing region 2100", which are provided by the resilient pad assembly.

[0182] As shown in Figure 24 and Figures 26A-29B , the resilient pad assembly includes a resilient pad 212" and a pair of heat-conducting plates 214" located on two sides of the resilient pad. The heat-conducting plates 214" are preferably bonded to the resilient pad 212".

[0183] 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”.

[0184] 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.

[0185] like Figure 24 as well as Figures 26A-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.

[0186] like Figure 24 as well as Figures 26A-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.

[0187] like Figure 24 as well as Figures 26A-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.

[0188] 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.

[0189] 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.

[0190] like Figure 24 as well as Figures 26A-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-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”.

[0191] 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.

[0192] The elastic frame of the high-voltage discharge assembly may also include a second bolt through hole (not shown).

[0193] like Figure 24 as well as Figures 26A-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.

[0194] 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.

[0195] Similar to the first or second embodiment, in the third embodiment, as... Figure 24As shown, the first gas inlet holes of the installed ground electrodes and the second gas inlet holes of the installed high-voltage discharge assemblies are aligned along the stacking direction to form a gas inlet passage across the ground electrodes, and the gas inlet passage is configured to be axially aligned with a gas inlet tube for the ozone generation unit. Similarly, the first gas outlet holes of the installed ground electrodes and the second gas outlet holes of the installed high-voltage discharge assemblies are aligned along the stacking direction to form a gas outlet passage across the ground electrodes, and the gas outlet passage is configured to be axially aligned with a gas outlet tube for the ozone generation unit. Similarly, the first flow inlet holes of the installed ground electrodes and the second flow inlet holes of the installed high-voltage discharge assemblies are aligned along the stacking direction to form a flow inlet passage across the ground electrodes, and the flow inlet passage is configured to be axially aligned with a flow inlet tube for the ozone generation unit. Similarly, the first flow outlet holes of the installed ground electrodes and the second flow outlet holes of the installed high-voltage discharge assemblies are aligned along the stacking direction to form a flow outlet passage across the ground electrodes, and the flow outlet passage is configured to be axially aligned with a flow outlet tube for the ozone generation unit.

[0196] Here, the reaction gas will enter the gas inlet passage from the gas inlet tube, then flow into the first gas path flow channel of each ground electrode across which it flows through the gas inlet micro-holes into the planar recess for reaction, and the generated gas will flow from the gas outlet holes into the second gas path flow channel and then into the gas outlet passage into the gas outlet tube. In this way, the gas supply (discharge) structure will not directly communicate with the planar recess.

[0197] Similarly, the cooling fluid will enter the flow inlet passage from the flow inlet tube, then flow into the parallel cooling flow channels of each ground electrode across which it flows into the flow outlet passage and then into the flow outlet tube. In this way, the cooling fluid branch will be dispensed with, and the cooling fluid supply and discharge will be provided by the flow inlet and outlet passages incorporated into the ozone generation unit.

[0198] With reference to the drawings Figures 30-33B An ozone generation unit 2"' according to a fourth embodiment of the present application is described. In the illustrated embodiment, the ozone generation unit 2"' can be configured as a plate-type ozone generation unit, and it can be modular, which can also be referred to herein as an ozone generation module.

[0199] In the illustrated fourth embodiment, the ozone generation unit 2"' can include a plurality of stacked ground electrodes, which are plate-type ground electrodes. In the illustrated fourth embodiment, the ground electrodes can include conventional ground electrodes 20". In the illustrated fourth embodiment, the ozone generation unit 2"' can also include a first end cap 22"' at a first end and a second end cap 23"' at a second end. In the illustrated fourth embodiment, the end cap 22"' or 23"' (which can also be referred to as an end ground electrode) can be configured as an end ground electrode, which can be implemented, for example, with reference to the end ground electrode 25"' of the third embodiment.

[0200] The ozone generation unit 2"' can further include a high-voltage discharge assembly 21"' disposed between the ground electrodes.

[0201] Correspondingly, the ground electrodes 20"' and the high-voltage discharge assemblies 21"' (as well as the end ground electrodes, the adjacent ground electrodes, and the high-voltage discharge assemblies therebetween) can collectively form a discharge chamber for the discharge reaction. However, unlike the first and second embodiments, in this fourth embodiment, the ozone generation unit 2"' is configured such that each ground electrode 20"', 22"', or 23"' is arranged alternately with each high-voltage discharge assembly 21"', i.e., not forming a ground electrode pair.

[0202] The ozone generation unit 2"' can further include an inflow pipe 261"', an outflow pipe 271"', an air inlet pipe 281"', and an air outlet pipe 291"' connected to the first end cover 22"'. The inflow pipe 261"', the outflow pipe 271"', the air inlet pipe 281"', and the air outlet pipe 291"' can also define the inflow interface 126, the outflow interface 127, the air inlet interface 128, and the air outlet interface 129.

[0203] With reference to Figures 30-33B The ground electrode 20"' can include a reaction zone 2000"' formed in both the first surface 201"' and the second surface 202"' of the one-piece body 200"'. The ground electrode 20"' can include a plurality of planar grooves 2010"', 2020"' extending laterally in the reaction zone.

[0204] Similarly, each planar groove 2010"' on the first surface 201"' includes a first curve at a first end 2013"' and a second curve at a 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"' can also include an air inlet micro-hole 2011"' and an air outlet hole 2012"' within an envelope of each planar groove 2010"', the air inlet micro-hole 2011"' being disposed proximate to the first end 2013"', and the air outlet hole 2012"' being disposed proximate to the second end 2014"'. The air inlet micro-hole 2011"' is disposed substantially at a focal point of the first parabolic curve. More specifically, a center of the air inlet micro-hole 2011"' can substantially coincide with the focal point of the first parabolic curve. Similarly, the air outlet hole 2012"' is disposed substantially at a focal point of the second parabolic curve. More specifically, a center of the air outlet hole 2012"' can substantially coincide with the focal point of the second parabolic curve.

[0205] Similarly to the first surface, each planar recess 2020"' on the second surface 202"' comprises a first curve at the first end 2023"' and a second curve at the second end 2024"'. In particular, 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"' can further comprise an air inlet micro-hole 2021"' and an air outlet hole 2022"' located within the envelope of each planar recess 2020"', the air inlet micro-hole 2021"' being located proximate to the first end 2023"' and the air outlet hole 2022"' being located proximate to the second end 2024"'. The air inlet micro-hole 2021"' is located substantially at the focal point of the first parabolic curve. More particularly, the centre of the air inlet micro-hole 2021"' can substantially coincide with the focal point of the first parabolic curve. Similarly, the air outlet hole 2022"' is located substantially at the focal point of the second parabolic curve. More particularly, the centre of the air outlet hole 2022"' can substantially coincide with the focal point of the second parabolic curve.

[0206] The structure and dimensions of the air inlet micro-hole and the air inlet hole of this fourth embodiment can refer to the first or second embodiment, but the air inlet micro-hole and the air inlet hole of the ground electrode 20"' of this fourth embodiment are provided in both surfaces.

[0207] Unlike the first to third embodiments, the sub-optimal embodiment illustrated in the fourth embodiment is not a thin ground electrode obtained by determining the thickness of the ground electrode based on the constraints of the micro-hole, 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 is modified into a thin ground electrode.

[0208] With reference to Figures 30-33B , the reaction zone 2000"' is substantially rectangular and the one-piece body 200"' of the ground electrode 20"' can further form, on both the first surface 201"' and the second surface 202"', a reaction zone circumferential groove 2019"', 2029"' delimiting the reaction zone 2000"'.

[0209] With reference to Figures 30-33B , the ground electrode 20"' further comprises a first pressure balancing structure. This first pressure balancing structure is in the form of a groove. In the illustrated embodiment, the first pressure balancing structure is formed only on the first surface, but it is conceivable that it is the other way around or that it is formed on both surfaces. In particular, the ground electrode 20"' comprises, within the reaction zone 2000", a flow splitting groove 2018"' connecting symmetrically one planar recess 2010"' (intermediate planar recess) at the first end 2013. This flow splitting groove 2018"' extends to and only to the air inlet micro-hole 2011"' in this planar recess.

[0210] With reference to Figure 24 and Figures 26A-26FPreferably, all planar grooves 2010"'on the first surface are almost closed, e.g. except for the shunt groove 2018"'; preferably, all planar grooves 2020"'on the second surface are closed.

[0211] Further fluid flow structures of the ground electrode 20"'are described below.

[0212] With reference to Figures 30-33B In addition to the reaction zone 2000" ', the ground electrode 20"'comprises a plurality of through holes which serve as part of the fluid supply channels of the ozone generation unit 2" ', here for example a first gas inlet through hole 282"'which serves as part of the gas inlet channel, a second gas outlet through hole 292"'which serves as part of the gas outlet channel, a first flow inlet through hole 262"'which serves as part of the flow inlet channel, and a first flow outlet through hole 272"'which serves as part of the flow outlet channel.

[0213] Similar to the third embodiment, with reference to Figures 30-33B The ground electrode 20"'can further comprise a first gas path flow channel 205"'formed inside the one-piece body 200" ', which is a vertical flow channel intersecting the first gas inlet through hole. The ground electrode 20"'can further comprise a second gas path flow channel 206"'formed inside the one-piece body 200" ', which is a vertical flow channel intersecting the first gas outlet through hole. The ground electrode 20"'can further comprise a cooling flow channel 204"'formed inside the one-piece body 200" ', which comprises a plurality of parallel vertical flow channels formed inside the one-piece body and a transverse communication structure 2042"'at the top and bottom and communicating the vertical flow channels, a first one of the plurality of parallel vertical flow channels intersecting the first flow inlet through hole and a second one of the plurality of parallel vertical flow channels intersecting the first flow outlet through hole.

[0214] However, unlike the third embodiment, with reference to Figures 30-33B In the fourth embodiment, the communication structure is located at a surface of the one-piece body, e.g. the first surface, whereby the flow channels in the fourth embodiment can be conventionally sealed with screws.

[0215] Since the fluid distribution structure is formed inside the one-piece body, the annular seal and the associated alignment positioning structure as described in the first or second embodiment can not be provided in the fourth embodiment.

[0216] In addition, a plurality of first bolt holes 207"'can be formed in the ground electrode 20" '.

[0217] The first end cap (end ground electrode) 22"'can be formed similar to the ground electrode 20" ', but with the difference that the first surface 221"'of the ground electrode 22"'is not provided with the reaction zone and the associated features.

[0218] With reference to Figures 30-33BThe first end cap 22"'can include a reaction zone 2200"'formed in the second surface 222"'of the single-piece body 220" '. The ground electrode 22"'can include a plurality of planar grooves 2220"'extending laterally in the reaction zone.

[0219] Each planar groove 2220"'on the second surface 222"'includes a first curve at a first end 2223"'and a second curve at a second end 2224" '.

Similarly, the air outlet hole 2222"'is disposed substantially at the focal point of the second parabolic curve. More specifically, the center of the air outlet hole 2222"'can substantially coincide with the focal point of the second parabolic curve.

[0220] The structure and size of the air inlet micro-hole and the air inlet hole of the first end cap 22"'can be referred to the ground electrode 20" ', but the air inlet micro-hole and the air inlet hole of the first end cap 22"'of the fourth embodiment are disposed in the second surface.

[0221] With reference to Figures 30-33B The reaction zone 2200"'is substantially rectangular, and the single-piece body 220"'of the first end cap 22"'can also form a reaction zone surrounding groove 2229"'in the second surface 222"'defining the reaction zone 2200" '.

[0222] With reference to Figures 30-33B Similarly to the ground electrode 20" ', the first end cap 22"'can also include a first pressure balancing structure. The first pressure balancing structure is in the form of a groove. Specifically, the first end cap 22"'includes a shunt groove 2218"'within the reaction zone 2200"'symmetrically connecting one planar groove 2210"'(the middle planar groove) at the first end 2213" '. The shunt groove 2018"'extends to and only to the air inlet micro-hole 2211"'in the planar groove.

[0223] With reference to Figures 30-33B Preferably, all the planar grooves 2520"'on the second surface are closed except for the shunt groove 2018"'described above.

[0224] Other fluid flow structures of the first end cap 22"'are described below.

[0225] With reference to Figures 30-33B In addition to the reaction zone 2200" ', the ground electrode 22" ', the first end cap 22"'further comprises a plurality of through holes serving as part of the fluid supply channels of the ozone generating unit 2" ', here for example a first inlet gas through hole 282"'as part of the inlet gas channel, a second outlet gas through hole 292"'as part of the outlet gas channel, a first inlet flow through hole 262"'as part of the inlet flow channel and a first outlet flow through hole 272"'as part of the outlet flow channel.

[0227] Similar to the ground electrode 20" ', with reference to Figures 30-33B The communication structure shown in the fourth embodiment is located at the surface of the one-piece body (e.g. the first surface), whereby the flow channels in the fourth embodiment can be conventionally sealed with screws.

[0228] Since the fluid distribution structure is formed inside the one-piece body, the annular seal and the associated alignment positioning structure as described in the first or second embodiment can not be provided in the fourth embodiment.

[0229] In addition, a number of first bolt holes 227"'can be formed in the first end cap 22" '.

[0230] Unlike the first or second embodiment, in the fourth embodiment, the through holes for fluid supply (discharge) are circular.

[0231] In addition, it will be appreciated that, although a ground electrode of one end portion is described above, a ground electrode of the opposite end portion can be envisaged.

[0232] With reference to Figures 30-33B The high voltage discharge assembly 21"'of the ozone generating unit 2"'of the fourth embodiment is described below.

[0233] As Figures 30-33BAs 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.

[0234] 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.

[0235] 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.

[0236] like Figures 30-33B 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”'. 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.

[0237] 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.

[0238] like Figures 30-33BAs shown, the elastic pad 212"' includes a plurality of balancing grooves, preferably two sets of balancing grooves 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 and second ends have beveled surfaces. In this embodiment, the plurality of balancing grooves form a plurality of balancing channels with the corresponding heat conducting plate 214"' for balancing gas flow. The number of the plurality of balancing grooves of the elastic pad 212"' corresponds to the number of planar grooves of the ground electrodes 20"', 22"' for reaction gas reaction, and at least some of the balancing grooves have substantially the same shape as the corresponding planar grooves.

[0239] As shown in FIG. 21, the elastic pad assembly can also have a notch to allow the elastic contact tab to pass through. The shape of the balancing grooves, except for the notch, is substantially the same as the shape of the corresponding planar grooves. Figures 30-33B

[0240] As shown in FIG. 21, the plurality of balancing grooves 2121"' have channels 2128"' between the elastic ridges 2122"' that communicate with the gap regions 2123"' between the elastic ridges. Figures 30-33B

[0241] Similar to the first, second, and third embodiments, the dielectric plate 216"' has an edge discharge suppression structure. In addition, as previously described, the elastic pad assembly forms a gap with the frame structure of the frame member 210"', whereby the gap forms a further edge discharge suppression structure.

[0242] As shown in FIG. 21, the elastic frame member 210"' of the high voltage discharge assembly 21"' can include a second gas inlet passage hole, a second gas outlet passage hole, a second flow inlet passage hole, and a second flow outlet passage hole outside of the dielectric plate 216"', which are formed by sealing rings. These sealing rings can engage the corresponding surrounding grooves of the ground electrodes that engage adjacent ground electrodes. Figure 1F

[0243] Similar to the third embodiment, the elastic frame member in the fourth embodiment does not form part of the thickness of the ozone generation unit, i.e., the relevant part of the thickness is formed by the ground electrodes, whereby the high voltage discharge assembly can be accommodated in a recessed reaction zone. Accordingly, unlike the first or second embodiments, the fourth embodiment does not have a pad block.

[0244] The elastic frame member of the high voltage discharge assembly can also include a second bolt passage hole (not shown).

[0245] The elastic frame member 210"' of the high voltage discharge assembly 21"' can also have a surrounding ridge that can be accommodated in the surrounding groove of the reaction zone to provide a seal.

[0246] ​​​Similarly to the third embodiment, the ground electrodes and high-voltage discharge assemblies of the fourth embodiment are alternately mounted, which can be mounted according to the conventional stacking, and can be fastened by the bolt fastening mechanism 24" '.

[0247] 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 here.

[0248] As described above, in particular with reference to Figure 1G and Figures 1A-33B The plate-type ozone generation unit 2 of the ozone generator 10 can be connected to the electrical elements through the wiring row (or wiring terminal).

[0249] As described above, the ozone generation unit 2 can include a plurality of stacked ground electrodes, and one or more high-voltage discharge assemblies arranged between the plurality of stacked ground electrodes. Accordingly, the one or more high-voltage discharge assemblies can be electrically connected to the high-voltage wiring row 3 (or high-voltage wiring terminal), and the ground electrodes can be electrically connected to the second bus bar 31, 31" (or second wiring terminal). Not shown in the figure, the high-voltage wiring row 3 (or high-voltage wiring terminal) can include or be connected to one or more parallel high-voltage fuse devices electrically connected to the plurality of high-voltage discharge devices. The above-mentioned electrical connection is achieved, for example, by a plug connector (not shown).

[0250] The high-voltage fuse device included in the ozone generator, such as the ozone generation unit, according to the embodiments of the present application can be a high-voltage fuse device dedicated to the ozone generator or generation unit.

[0251] Accordingly, the second bus bar 31 can be connected to the wiring ground terminal, which is fixed to the ground electrode 20, for example, by means of a screw.

[0252] The specific structure of the high-voltage wiring row, high-voltage fuse device, second bus bar, etc. will not be described here, as it is not the focus.

[0275] The first group of embodiments relates to Figures 1A-29B , and relates to a novel ground electrode structure.

[0276] In some technologies known to the inventor, it is proposed to achieve the generation of ozone gas by planar grooves as reaction space.

[0277] In further technologies known to the inventor based on planar grooves, it is "desired" to provide as large a flow of reaction gas as possible in the planar micro-grooves to provide more reaction gas to the planar micro-grooves and to provide a higher flow of generated gas, for which open ends are formed at both ends of the planar grooves, and long holes or elongated grooves are formed in the recessed areas to form elongated gas cavities in the recessed areas of the stacked ground electrodes.

[0278] In another technology known to the inventor based on planar grooves, gas inlet and outlet holes are formed in the planar grooves of the pair of ground electrodes, which pass through the ground electrode. And based on the "desire" to improve the flow of reaction gas, a plurality of gas inlet through holes and a plurality of gas outlet through holes are used in the technology, which pass through the body of the ground electrode, and a further recessed seat is formed from the planar groove at the position of the gas inlet through hole and the gas outlet through hole as a smooth diffusion structure.

[0279] However, the present inventors have found that, by significantly reducing the size of the inlet holes of the communicating planar grooves to be micro-inlet holes (the size of the outlet holes can have a higher margin) and allowing the micro-inlet holes to be adjacent to the curved end in the embodiment 1.1 of the present application, the ozone reaction efficiency can be significantly improved, and the ozone generation unit has a significantly higher yield per unit volume (unit weight). Compared with the two aforementioned technologies based on planar grooves, the structure of the micro-inlet holes and the curved end combined thereof in the embodiment of the present application intentionally reduces the size of the flow inlet, to some extent, against the intuition of expanding the flow inlet as much as possible to increase the flow of reaction gas and thus improve the gas production efficiency; and also saves the specially arranged diffusion structure, achieving unexpected effects. Accordingly, the embodiment 1.1 of the present application further improves the gas production efficiency by combining the curved end with the outlet holes, but the present inventors realize that the design of the size of the outlet holes can have a higher margin (as described in embodiment 1.5), rather than necessarily being reduced to micro-holes.

[0280] Further, more surprisingly, it is found that, by the parabolic curve, especially by arranging the micro-inlet holes (and preferably also the outlet holes) at the focal point of the parabolic curve, especially coinciding with the focal point, the embodiments 1.2 and 1.3 of the present application can more optimally improve the gas production efficiency by providing smooth gas flow along the curve.

[0281] Further, the embodiments 1.4 and 1.5 of the present application can further improve the reaction gas flow distribution effect by making part or almost all of the curved end form a closed end, thereby further improving the gas production efficiency.

[0282] In addition, the structure of the micro-inlet holes (and the outlet holes) combined with the curved end adopted in the embodiments of the present application makes it unnecessary for the reaction zone to be a recessed area or to be formed in a recessed area, which makes it possible to realize the compact structure of the ozone generation unit and its discharge chamber, and also makes it possible to have a thin electrode, as described in the eighth group of embodiments.

[0283] In addition, the micro-inlet holes described in the embodiments of the present application also allow the electrode itself to form an efficient and compact reaction gas distribution structure and a cold zone fluid distribution structure and associated structures (as described in embodiments 1.9 to 1.14), and it is also possible to form advantageous applications by combining the micro-inlet holes with these structures, such as novel fluid distribution structures and related sealing and positioning structures.

[0284] In addition, the micro-inlet hole structure described in the embodiments of the present application makes it possible to have novel discharge chamber related components, structures or parts, such as novel electrodes, high-voltage discharge assemblies and related pressure balancing structures, heat balancing structures, surface discharge suppression structures, etc.

[0297] Embodiment 8.11, an ozone generator, comprising at least one ozone generation unit according to Embodiment 8.10.

[0298] The eighth group of embodiments relates to ​ and to novel thin ground electrodes of ozone generation units.

[0299] In the related art of ozone-related devices such as plate-type ozone generators, although product thinning is one of the goals pursued, it is ranked behind key indicators such as gas production efficiency, continuous operation time, and working life, and due to safety redundancy requirements, related designers often do not consider or are difficult to come up with design ideas for thinning the ground electrode.

[0300] However, in the embodiments of the present application, the inventors propose to significantly reduce the flow of the reaction gas through the gas inlet micro-holes (the outlet hole size can have a higher margin or even other outlet structures), which can help to significantly improve the ozone reaction efficiency, so that the ozone generation unit has significantly higher unit volume (unit weight) production. On this basis, in the eighth group of embodiments of the present application, the inventors innovatively propose novel structures of thin ground electrodes for single-sided reaction (such as Embodiment 8.1) and double-sided reaction (such as Embodiment 8.5) ground electrode structures, respectively, with the gas inlet micro-holes (reduced flow) as a constraint. In comparison, the ground electrode can have a thickness of 2 to 6 times.
