[0052] It will be understood that the ozone generator may optionally be equipped with the above-mentioned or other processing circuits, transformer mechanisms and / or power conversion modules and other functional components related to the power supply and monitoring of the ozone generator as needed, which will not be described in detail here.

[0056] For example, in another embodiment, a rack-type ozone generator may be provided, which may include a rack, a plurality of ozone generating units, a gas distribution system, and a cooling fluid distribution system. In this rack-type ozone generator, the plurality of ozone generating units may share one or more sets of electrical components.
[0057] For example, in another embodiment, an ozone generating apparatus combining a rack and an integrated ozone generator may 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] Combined with reference Figures 2A-13C , describing 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 embodiment shown, the ozone generating unit 2 may include a plurality of stacked ground electrodes, which are plate-type ground electrodes, as described below with reference to Figures 3A to 4D As stated.
[0060] The ozone generating unit 2 may further include a high voltage discharge assembly disposed between the ground electrodes, as described below with reference to Figures 3A to 3C as well as Figures 5A to 10B As stated.
[0061] Accordingly, if Figures 3A to 3C As shown, the ground electrode 20 and the high-voltage discharge assembly 21 can jointly form a discharge chamber for 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 air outlet pipe 290 connected to the first end cover 22. The inlet pipe 260, the outlet pipe 270, the air inlet pipe 280, and the air outlet pipe 290 define an inflow interface 126, an outflow interface 127, an air inlet interface 128, and an air outlet interface 129.
[0064] Continue to refer Figures 3A to 4D A plurality of stacked plate-type ground electrodes 20 according to some embodiments of the present invention are described. In the illustrated embodiment, the plate-type ground electrode 20 may include a single-piece or integral body. The body of the plate-type ground electrode 20 may be made of an aluminum alloy coated with a nano-ceramic material.
[0065] like Figure 4A and Figure 4C As shown, the ground electrode 20 may include a reaction zone 2000 formed within at least one of the first surface 201 and the second surface 202 of the single-piece body 200, and a plurality of planar grooves 2010 extending transversely within the reaction zone. In the illustrated embodiment, the reaction zone 2000 is formed only on the first surface 201. In embodiments of the present invention, the planar grooves 2010 may also be referred to as planar (micro) grooves. Thus, the planar grooves 2010, together with the dielectric plate 216 of the high-voltage discharge assembly 21, can form gas (micro) flow channels with an extremely high aspect ratio. 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] like Figure 4A and Figure 4C As shown, each planar groove 2010 includes a first curve at a first end 2013 and a second curve at a second end 2014. Specifically, the first curve 2015 may be a first parabola 2015, and the second curve 2016 may be a second parabola 2016.
[0067] like Figure 4A and Figure 4C As shown, the ground electrode 20 may further include an air inlet micropore 2011 and an air outlet pore 2012 located within the envelope of each planar groove 2010, wherein the air inlet micropore 2011 is disposed adjacent to the first end 2013 and the air outlet pore 2012 is disposed adjacent to the second end 2014. Figure 4A and Figure 4C In the illustrated embodiment, the air inlet micropore 2011 is positioned approximately at the focus of the first parabola. More specifically, the center of the air inlet micropore 2011 may approximately coincide with the focus of the first parabola. Similarly, the air outlet 2012 is positioned approximately at the focus of the second parabola. More specifically, the center of the air outlet 2012 may approximately coincide with the focus of the second parabola.
[0068] In the embodiment of the present application, the "micropore" can be specifically determined based on the size of the ground electrode 20, for example, less than or equal to 2 mm. In a preferred embodiment, the air inlet micropore 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.
[0069] In the embodiment of the present application, the thickness of the ground electrode can be determined based on the constraints of the micropores, thereby obtaining a thin ground electrode. Figures 2A to 13C In the illustrated embodiment, the ratio of the thickness of the ground electrode's single-piece body to the diameter of the air inlet micropores 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, and more preferably greater than or equal to 8 and less than or equal to 15. Preferably, the single-piece body has a thickness of 3 mm to 15 mm, preferably 3 mm to 10 mm, and more preferably 4 mm to 6 mm. It will be appreciated that the intersection of the two can be used. In the illustrated preferred embodiment, the air inlet micropores can have a thickness of 0.3 mm, and the ratio of the thickness of the single-piece body to the diameter of the air inlet micropores can be 13.3.
[0070] As described herein, the exhaust pores 2012 are not limited to being "micropores" and can have a wider range of pore sizes. In a preferred embodiment, the ratio of the pore size of the exhaust pores 2012 to the pore size of the inlet micropores 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.
[0071] like Figure 4A and Figure 4C As shown, the reaction zone 2000 is substantially rectangular, and the single-piece body 200 of the ground electrode 20 may further form a reaction zone surrounding groove 2019 on the first surface 201 that defines the reaction zone 2000. Thus, features on the first surface 201 that are located outside the reaction zone 2000 are sealed and isolated from the reaction zone 2000.
[0072] like Figure 4A and Figure 4C As shown, the ground electrode 20 also includes a first pressure balancing structure. The first pressure balancing structure is in the form of a groove. Specifically, the ground electrode 20 includes a diversion groove 2018 located in the reaction zone 2000 and symmetrically connected to one or more planar grooves 2010 at the first end 2013. Figure 4A and Figure 4C As shown, the diversion groove 2018 connects the topmost planar groove 2010 and the bottommost planar groove 2010. Figures 3A to 5B The diversion groove 2018 extends beyond the envelope of the dielectric plate 216 of the high-voltage discharge assembly 21 to divert the reaction gas in the corresponding planar groove 2010 to the high-voltage discharge assembly 21, as further described below.
[0073] Continue to refer Figure 4A and Figure 4C , preferably all planar grooves 2010 are “almost” closed, for example except for the diverter grooves 2018 .
[0074] Other fluid flow structures of the ground electrode 20 are described below.
[0075] Continue to refer Figures 4A to 4D As shown, outside the reaction zone 2000, the ground electrode 20 also includes a plurality of through holes used as part of the fluid supply channel of the ozone generating unit 2, such as the first air inlet through hole 282 as part of the air inlet channel, the first exhaust through hole 292 as part of the exhaust channel, the first air inlet flow hole 262 as part of the inlet channel, and the first exhaust flow hole 272 as the exhaust channel.
[0076] like Figure 4B and Figure 4D As shown, the single-piece body 200 may further include a first air flow channel 2021 communicating with the air inlet micropores 2011, a second air flow channel 2022 communicating with the air outlet pores 2012, and a cooling flow channel 2020 on the second surface 202. All of these are open flow channels. Here, the cooling flow channel 2020 has a zigzag structure, such as an M-shape.
[0077] Specifically, if Figure 4B and Figure 4D As shown, the first air path channel 2021 is orthogonal to the first air inlet through hole 282, the second air path channel 2022 is orthogonal to the first exhaust through hole 292, one end of the cooling channel 2020 is orthogonal to the first air inlet flow hole 262, and the other end is orthogonal to the first row of flow holes 272, the air inlet micropore 2011 connects the first air path channel 2021 and the corresponding planar groove 2010, and the exhaust hole 2012 connects the corresponding planar groove 2010 and the second air path channel 2022.
[0078] like Figure 4B and Figure 4D As shown, the first air path 2021 on the second surface 202 is connected to the air inlet micropore 2011 on the first surface 201 through the stepped hole structure 2026. The aperture of the stepped hole structure 2026 is larger than the aperture of the air inlet micropore 2011. Specifically, the stepped hole structure 2026 is a single-stage stepped hole or a multi-stage stepped hole. The aperture of the single-stage stepped hole or the first-stage aperture of the multi-stage stepped hole can be approximately equal to the aperture of the exhaust hole 2012. Figure 4B and Figure 4D In the illustrated embodiment, the stepped hole structure 2026 is a single-stage stepped hole.
[0079] Therefore, if Figures 3A to 4D As shown, the first air inlet hole 282, the first air path channel 2021, the air inlet micropores 2011, the planar grooves 2010, the exhaust holes 2012, the second air path channel 2022 and the first exhaust hole 292 sequentially form an airflow distribution structure in the ground electrode 20.
[0080] like Figure 4A and Figure 4CAs shown, the ground electrode 20 forms a surrounding groove surrounding the first air inlet through hole 282 , a surrounding groove surrounding the first air outlet through hole 292 , a surrounding groove surrounding the first air inlet flow hole 262 , and a surrounding groove surrounding the first row of flow holes 272 on the first surface 201 .
[0081] Similarly, if Figures 3A to 4D As shown, the inlet flow hole 262 , the tortuous cooling flow channel 2020 and the exhaust flow hole 272 sequentially form a cooling flow distribution structure in the ground electrode 20 .
[0082] like Figure 4B and Figure 4D Combine Figure 11 and Figure 12 As shown, the second surface 202 of the single-piece body 200 may further form a first gas path surrounding groove 2024 surrounding the first gas path flow channel 2021 and the intake through-hole 282, a second gas path surrounding groove 2025 surrounding the second gas path flow channel 2022 and the exhaust through-hole 293, and a cooling flow surrounding groove 2023 surrounding the intake flow hole 262, the cooling flow channel 2020, and the exhaust flow hole 272. Accordingly, a first gas path surrounding seal 204 may be installed in the first gas path surrounding groove 2024, a second gas path surrounding seal 205 may be installed in the second gas path surrounding groove 2025, and a cooling flow surrounding seal 203 may be installed in the cooling flow surrounding groove 2023.
[0083] In the embodiment shown, Figures 2A to 2C As shown, the ground electrodes 20 can be aligned with each other at their second surfaces 202, such that the first gas flow channels 2021 of the pair of ground electrodes 20 jointly form a circumferentially closed first airflow space, the second gas flow channels 2022 jointly form a circumferentially closed second airflow space, and the cooling flow channels 2020 jointly form a circumferentially closed cooling flow space. Thus, the aligned first gas flow surrounding grooves 2024 of the aligned pair of ground electrodes 20 can jointly accommodate the first gas flow surrounding seal 204, the aligned second gas flow surrounding grooves 2025 can jointly accommodate the second gas flow 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 path surrounding groove and the cooling flow surrounding groove have a common section; the second air path surrounding groove and the cooling flow surrounding groove have a common section. Preferably, the first air path surrounding seal and the cooling flow surrounding seal have a slightly larger width in the common section and form an extrusion seal in the common section; the second air path surrounding seal and the cooling flow surrounding seal have a slightly larger width in the common section and form an extrusion seal in the common section.
[0085] These seals may serve as alignment features for grouping the ozone generating units, as further described below.
[0086] In addition, a plurality of first bolt holes 207 may be formed in the ground electrode 20 .
[0087] The following reference Figures 3A to 3C as well as Figures 5A to 10B , describing the high voltage discharge components of the ozone generating unit 2.
[0088] 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 .
[0089] 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 further include an elastic pad assembly.
[0090] like 5A to 6D As shown, the elastic frame member 210 includes a joint portion 2110, a terminal held by the joint portion and extending from the top of the joint portion, and a pair of elastic contact pieces 2111 electrically connected to the terminal. The pair of elastic contact pieces electrically contact the back sides of the pair of dielectric plates 216. The joint portion 2110 can be accommodated in the limiting groove 2017 ( Figure 4C )middle.

Figures 3A to 3C as well as Figure 5A and Figure 5BThe first pressure balancing groove 2103 extends beyond the envelope of the dielectric plate 216, thereby connecting to 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 area 2100. The pressure balancing area can be a hollow portion 2101 formed in the elastic frame member 210.

The body 2140 of the heat conducting plate 214 is made of a heat conducting metal material, such as stainless steel, and may be treated with suitable materials.
[0095] like Figures 5A to 5B The elastic pad assembly is mounted in a floating manner in the thickness direction, so that the elastic pad assembly is spaced apart from the frame structure of the elastic frame member 210, thereby forming a first gap G1 on a first side of the pressure balance area 2100 and a second gap G2 on an opposite second side. In addition, gaps may also be formed at the top and bottom of the elastic pad assembly.
[0096] refer to Figures 7A to 8B The elastic pad 212 includes a plurality of balancing grooves 2121, preferably two groups of balancing grooves 2121 located on both sides of the elastic pad.

[0098] Continue to refer FIG. 10A to FIG. 10B The dielectric plate 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 plate 216 has a conductor coating area 2161 on the back side that is in electrical contact with the elastic contact piece and a glaze coating area 2162 on the front side facing the reaction zone. The dielectric plate 216 also includes an uncoated edge area 2163 surrounding the conductor coating area 2161. The conductor coating area 2161 can be a silver coating area. Figures 3A to 3C as well as Figure 10A and Figure 10B The uncoated edge area 2163 is configured so that the conductor coating area 2161 is separated from the frame structure of the frame member 210, and the thermal conductive plate 214 of the elastic pad assembly basically covers the conductor coating area 2161, thereby forming a surface discharge suppression structure.
[0099] In addition, as mentioned above, the elastic pad assembly and the frame structure of the frame member 210 form gaps G1, G2, etc., whereby the gaps form a further creeping discharge suppression structure.

These sealing ribs may engage with corresponding surrounding grooves of the ground electrode 20 that engage with adjacent ground electrodes.
[0101] These sealing ridges can also serve as alignment and positioning structures for the ground electrode 20 and the high-voltage discharge assembly 21 .

[0104] refer to 5A to 6D The elastic frame member 210 of the high-voltage discharge assembly 21 may also have a surrounding ridge 2119, which can be accommodated in the reaction zone surrounding groove 2019 to provide sealing.
[0105] The following will refer to Figures 2A to 13C The installation (grouping) and corresponding alignment and sealing of the ozone generating unit 2 according to the first embodiment of the present application are described.
[0106] In the assembled ozone generating unit 2, the ground electrodes 20 are arranged in pairs, wherein the paired ground electrodes 20 are attached to each other on the second surface 202, and adjacent pairs of ground electrodes 20 are opposed to each other on the first surface 201 and sandwiched with a high-voltage discharge assembly 21, thereby forming a discharge chamber between the first surfaces 201 of the opposing ground electrodes 20 (and the high-voltage discharge assembly 21). Figures 2A to 2C As best shown, the elastic frame member 210 (frame structure) of the high voltage discharge assembly 21 also constitutes a portion of the thickness of the ozone generating unit 2 .
[0107] The following continues to describe the assembly of the ozone generating unit 2. First, the second end cover 23 can be placed on a plane, and the ground electrode 20 and the high-voltage discharge assembly 21 can be stacked according to the stacking method described above (for example, except for the ground electrode 20 at the end, a high-voltage discharge assembly 21 is stacked after every two ground electrodes 20 are stacked). At this time, the adjacent ground electrodes 20 and the adjacent high-voltage discharge assemblies 21 are pre-aligned with the aid of an alignment and positioning structure, which includes but is not limited to the first gas path surrounding seal 204 contained in the first gas path surrounding groove 2024 of the adjacent ground electrodes 20, the second gas path surrounding seal 205 contained in the second gas path surrounding groove 2025 of the adjacent ground electrodes 20, and the cooling flow surrounding seal 203 in the cooling flow surrounding groove 2023 of the adjacent ground electrodes 20, and the sealing rib 2113 surrounding the second air inlet through hole 283, the sealing rib 2114 surrounding the second exhaust through hole 293, the sealing rib 2115 surrounding the second inlet flow hole 263, and the sealing rib 2116 surrounding the second row of flow holes 273. Figure 3B and Figure 4B As shown, the alignment and positioning structure on the second surface 202 occupies at least 60%, preferably 70%-90% of the lateral dimension and at least 60%, preferably 70%-90% of the vertical dimension of the single-piece 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 on the upper end, so that the alignment and positioning structure is accurately self-aligned due to being pressed. Figure 2C As 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 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 to distinguish different end caps, and do not limit the use of specific end caps for compression.
[0109] Subsequently, the bolts 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 holes 221 of the second end cover 23 through the threads provided in the bolt holes 221 of the second end cover 23.
[0110] Through the above assembly process, the various components of the ozone generating unit 2 can be accurately aligned and sealed, thereby ensuring the performance and stability of the equipment.
[0111] The following describes the fluid supply (exhaust) of the assembled ozone generator and the fluid distribution within the electrodes.
[0112] Combined with reference Figure 2A and Figure 3CThe first air inlet holes of each electrode of the installed ozone generating unit and the second air inlet holes of each high-voltage discharge assembly are aligned along the stacking direction to form an air inlet channel that spans each electrode, and the air inlet channel is configured to be axially aligned with the air inlet pipe for the ozone generating unit. Similarly, the first exhaust holes of each electrode of the installed ozone generating unit and the second exhaust holes of each high-voltage discharge assembly are aligned along the stacking direction to form an exhaust channel that spans each electrode, and the exhaust channel is configured to be axially aligned with the exhaust pipe for the ozone generating unit. Similarly, the first inlet holes of each electrode of the installed ozone generating unit and the second inlet holes of each high-voltage discharge assembly are aligned along the stacking direction to form an inlet channel that spans each electrode, and the inlet channel is configured to be axially aligned with the inlet pipe for the ozone generating unit. Similarly, the first row of flow holes of each electrode of the installed ozone generating unit and the second row of flow holes of each high-voltage discharge assembly are aligned along the stacking direction to form a discharge channel that spans each electrode, and the discharge channel is configured to be axially aligned with the discharge pipe for the ozone generating unit.
[0113] Here, the reactant gas will enter the intake channel from the aforementioned intake pipe, then flow into the first gas flow channel of each crossed ground electrode (the ground electrode pair in close contact), pass through the intake micropores, and then enter the planar groove for reaction. The generated gas will flow from the exhaust hole to the second gas flow channel, then into the exhaust channel and into the exhaust pipe. Therefore, the gas supply (exhaust) structure will not be directly connected to the planar groove.
[0114] Similarly, the cooling fluid will enter the inlet channel from the aforementioned inlet pipe, then flow into the M-shaped cooling channel of each crossing ground electrode (the ground electrode pair in close contact), and then flow into the discharge channel and then into the discharge pipe. As a result, the cooling fluid branch pipe will be eliminated, and the inlet and discharge channels integrated into the ozone generation unit will provide cooling fluid supply and discharge.

Specifically, the ground electrode 20" includes a diverter groove 2018" located in the reaction zone 2000 and symmetrically connected to a planar groove 2010" (middle planar groove) at the first end 2013. The diverter groove 2018" extends to and only extends to the air inlet micropore 2011" in the planar groove.

[0159] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and the associated alignment and positioning structure as described in the first or second embodiment may not be provided in the third embodiment.
[0160] In addition, a plurality of first bolt holes 207" may be formed in the ground electrode 20".
[0161] The ground electrode 25 ″ may be formed similarly to the ground electrode 20 ″, but differs in that the first surface 251 ″ of the ground electrode 25 ″ is not provided with a reaction zone and related features.

[0163] Each planar recess 2520" on the second surface 252" includes a first curve at the first end 2523" and a second curve at the second end 2524".

[0164] The structure and size of the air inlet micro-hole and the air inlet hole of the ground electrode 25" can be similar to those of 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 constraint of the micro-hole, thereby obtaining a thin ground electrode.
[0166] Reference is made to Figure 24 and Figures 25A to 25F The reaction zone 2500" is substantially rectangular, and the one-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] Reference is made to Figure 24 and Figures 25A to 25F Unlike the ground electrode 20", the ground electrode 25" does not have the first pressure balancing structure. However, it is contemplated that the first pressure balancing structure can be provided in the ground electrode 25".
[0168] Reference is made to Figure 24 and Figures 25A to 25F Preferably, all the planar recesses 2520" on the second surface are closed.
[0169] Other fluid flow structures of the ground electrode 25" are described below.
[0170] Reference is made to Figure 24 and Figures 25A to 25FOutside the reaction zone 2500", the ground electrode 20" also includes a plurality of through holes used as part of the fluid supply channel of the ozone generating unit 2", 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 air inlet flow hole 262" as part of the inlet channel, and a first exhaust flow hole 272" as the exhaust channel.
[0171] Unlike the first and second embodiments, reference Figure 24 and Figures 25A to 25F The ground electrode 25" may also include a first gas path flow channel 255" formed inside the single-piece body 250", which is a vertical flow channel intersecting with the first air inlet through hole.

[0173] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and the associated alignment and positioning structure as described in the first or second embodiment may not be provided in the third embodiment.
[0174] In addition, a plurality of first bolt holes 257" may be formed in the ground electrode 25".
[0175] Unlike the first or second embodiment, in the third embodiment, the through hole for fluid supply (discharge) is circular.
[0176] Furthermore, it will be appreciated that although a ground electrode at one end is described above, a ground electrode at the other end that is symmetrical is contemplated.
[0177] The following reference Figure 24 as well as Figures 26A to 29B , describing the high-voltage discharge assembly 21 ″ of the ozone generating unit 2 ″ of the third embodiment.
[0178] 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 further include an elastic pad assembly.
[0179] like Figure 24 as well as Figures 26A to 29B As shown, the elastic frame member 210" includes a joint portion 2110", a terminal held by the joint portion and extending from the top of the joint portion, and a pair of elastic contact pieces 2111" electrically connected to the terminal, the pair of elastic contact pieces electrically contacting the back sides of the pair of dielectric plates 216. The joint portion 2110" can be accommodated in a limiting groove 2017" or 2527".
[0180] The elastic frame member 210" may have a frame structure that defines a pressure balance zone 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"", which has a pair of openings. The V-shaped pressure balance groove extends beyond the envelope of the dielectric plate 216", thereby connecting to 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 balance zone 2100". The pressure balance zone can be a hollow portion 2101" formed in the elastic frame member 210".
[0181] As shown in the figure, a number of laterally extending balancing channels will be set in the pressure balancing area 2100", which are provided by elastic pad assemblies.
[0182] 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".
[0183] As shown in the figure, the elastic pad assembly 212" is floatingly mounted in the pressure balance area 2100" of the elastic frame member 210" in the thickness direction. 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". Accordingly, 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 installed in a floating manner in the thickness direction so that the elastic pad assembly is spaced apart from the frame structure of the elastic frame member 210", so as to form a first gap G1" on a first side of the pressure balance area 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 to 29B As shown, the elastic pad 212" includes a plurality of balancing grooves 2121", preferably two groups of balancing grooves 2121" located on both side surfaces 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 a beveled surface. In this embodiment, the plurality of balancing grooves and the corresponding heat conducting plates 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 reaction of the reaction gas of the ground electrodes 20", 25", and at least some of the balancing grooves have a shape substantially the same as that of the corresponding planar grooves.
[0186] like Figure 24 as well as Figures 26A to 29B As shown, the elastic pad assembly may further have a notch for allowing the elastic contact piece 2111 ″. The shape of the balancing groove except the notch is substantially the same as that of the corresponding planar groove.
[0187] like Figure 24 as well as Figures 26A to 29B As shown, there are connecting channels 2128" between the plurality of balancing grooves 2121" and gap areas 2123" between the elastic ridges 2122".
[0188] Similar to the first and second embodiments, the dielectric plate 216" has a single-piece body and includes a positive side facing the ground electrode and a back side facing away from the ground electrode. The dielectric plate has a conductor coating area on the back side that is in electrical contact with the elastic contact piece and a glaze coating area on the positive side facing the reaction area. The dielectric plate 216" also includes an uncoated edge area surrounding the conductor coating area. Similarly, a surface discharge suppression structure is formed.
[0189] In addition, 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 creeping discharge suppression structure.
[0190] 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 hole 283", a second air outlet hole 293", a second air inlet hole 263", and a second row of air holes 273" located outside the dielectric plate 216". Figure 24 as well as Figures 26A to 29B As shown, the second air inlet through-hole 283", the second air outlet through-hole 293", the second air inlet flow hole 263" and the second row of flow holes 273" are formed by sealing rings. These sealing rings can engage corresponding surrounding grooves of the ground electrode 20" that engage adjacent ground electrodes.
[0191] Unlike the first or second embodiments, the elastic frame member in the third embodiment does not constitute a portion of the thickness of the ozone generating unit. Specifically, the relevant portion of the thickness 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 include a spacer.
[0192] The elastic frame member of the high-voltage discharge assembly may further include a second bolt through hole (not shown).
[0193] 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 also have a surrounding rib 2119 ″, which may be accommodated in the reaction zone surrounding groove 2019 ″ to provide sealing.
[0194] Different from the first or second embodiment, the ground electrode and the high-voltage discharge assembly of the third embodiment are installed alternately. The installation method can be performed according to the conventional stacking method and can be tightened by a bolt tightening mechanism.
[0195] Similar to the first or second embodiment, in the third embodiment, as Figure 24 As shown, the first air inlet through-holes of each electrode of the installed ozone generating unit 2" and the second air inlet through-holes of each high-voltage discharge assembly are aligned in the stacking direction to form an air inlet channel that spans each electrode, and the air inlet channel is configured to be axially aligned with the air inlet pipe for the ozone generating unit. Similarly, the first exhaust through-holes of each electrode of the installed ozone generating unit and the second exhaust through-holes of each high-voltage discharge assembly are aligned in the stacking direction to form an exhaust channel that spans each electrode, and the exhaust channel is configured to be axially aligned with the exhaust pipe for the ozone generating unit. Similarly, the first inlet flow holes of each electrode of the installed ozone generating unit and the second inlet flow holes of each high-voltage discharge assembly are aligned in the stacking direction to form an inlet flow channel that spans each electrode, and the inlet flow channel is configured to be axially aligned with the inlet flow pipe for the ozone generating unit. Similarly, the first row of flow holes of each electrode of the installed ozone generating unit and the second row of flow holes of each high-voltage discharge assembly are aligned in the stacking direction to form a discharge channel that spans each electrode, and the discharge channel is configured to be axially aligned with the discharge pipe for the ozone generating unit.
[0196] Here, the reactant gas will enter the inlet channel from the aforementioned inlet pipe, then flow into the first gas flow channel of each crossing ground electrode, pass through the gas inlet micropores, and then enter the planar groove for reaction. The generated gas will flow from the exhaust hole to the second gas flow channel, then into the exhaust channel and into the exhaust pipe. Therefore, the gas supply (exhaust) structure will not directly connect to the planar groove.
[0197] Similarly, the cooling fluid will flow from the aforementioned inlet pipe into the inlet channel, then into the parallel cooling channels of each ground electrode, and then into the outlet channel and finally into the outlet pipe. Thus, the cooling fluid branch pipe is eliminated, and the inlet and outlet channels integrated into the ozone generating unit provide cooling fluid supply and exhaust.
[0198] Combined with reference Figure 30-33B , describing 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 can also be referred to as an ozone generating module in this article.
[0199] 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 electrode may include a conventional ground electrode 20". In the fourth embodiment shown, 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. In the fourth embodiment shown, the end cap 22'' or 23'' (also referred to as an end ground electrode) may be configured as an end ground electrode, which may be implemented, for example, with reference to the end ground electrode 25'' of the third embodiment.
[0200] The ozone generating unit 2''' may further include a high voltage discharge assembly 21''' disposed between the ground electrodes.
[0201] Accordingly, the ground electrode 20'' and the high-voltage discharge assembly 21'' (as well as the end ground electrode, the adjacent ground electrode and the high-voltage discharge assembly therebetween) can jointly 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'' and the high-voltage discharge assemblies 21'' are alternately arranged, that is, no ground electrode pair is formed.
[0202] The ozone generating unit 2'' may further include an inlet pipe 261'', an outlet pipe 271'', an air inlet pipe 281'', and an exhaust pipe 291'' connected to the first end cover 22''.

[0203] Combined with reference Figure 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'', 2020'' extending laterally in the reaction zone.
[0204] 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 parabola 2015"', and the second curve can be a second parabola 2016"'. Similarly, the ground electrode 20"' may also include an air inlet micropore 2011"' and an air outlet pore 2012"' located within the envelope of each planar groove 2010"', the air inlet micropore 2011"' being arranged adjacent to the first end 2013"', and the air outlet pore 2012"' being arranged adjacent to the second end 2014"'. The air inlet micropore 2011"' is approximately arranged at the focus of the first parabola. More specifically, the center of the air inlet micropore 2011"' may approximately coincide with the focus of the first parabola. Similarly, the air outlet hole 2012'' is substantially disposed at the focus of the second parabola. More specifically, the center of the air outlet hole 2012'' may substantially coincide with the focus of the second parabola.
[0205] 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 parabola 2025"', and the second curve can be a second parabola 2026"'. Similarly, the ground electrode 20"' may also include an air inlet micropore 2021"' and an air outlet pore 2022"' located within the envelope of each planar groove 2020"', the air inlet micropore 2021"' being arranged adjacent to the first end 2023"', and the air outlet pore 2022"' being arranged adjacent to the second end 2024"'. The air inlet micropore 2021"' is approximately arranged at the focus of the first parabola. More specifically, the center of the air inlet micropore 2021"' may approximately coincide with the focus of the first parabola. Similarly, the air outlet hole 2022''' is substantially disposed at the focus of the second parabola. More specifically, the center of the air outlet hole 2022''' may substantially coincide with the focus of the second parabola.
[0206] The structure and size of the air inlet micropores and air inlet holes of the fourth embodiment may refer to the first or second embodiment, but the air inlet micropores and air inlet holes of the ground electrode 20'' of the fourth embodiment are provided on both surfaces.
[0207] 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 constraints of the micropores, but rather a ground electrode of conventional thickness. However, it is conceivable that the other features of this embodiment can be combined with other embodiments in a non-incompatible manner, or that this embodiment can be modified to form a thin ground electrode.
[0208] Combined with reference Figure 30-33BThe reaction zone 2000'' is roughly rectangular, and the single-piece body 200'' of the ground electrode 20'' can also form reaction zone surrounding grooves 2019'' and 2029'' on the first surface 201'' and the second surface 202'' to define the reaction zone 2000''.
[0209] Combined with reference Figure 30-33B , the ground electrode 20'' also includes 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 only on the first surface, but it is conceivable that it is formed in reverse or on both surfaces. Specifically, the ground electrode 20'' includes a diverter groove 2018'' located in the reaction zone 2000 and symmetrically connected to a planar groove 2010'' (middle planar groove) at the first end 2013. The diverter groove 2018'' extends to and only extends to the air inlet micropores 2011'' in the planar groove.
[0210] 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 diverter grooves 2018''; preferably, all planar grooves 2020'' on the second surface are closed.
[0211] Other fluid flow structures of the ground electrode 20'' are described below.
[0212] Combined with reference Figure 30-33B Outside the reaction zone 2000', the ground electrode 20'' further includes a plurality of through holes serving as part of a fluid supply channel of the ozone generating unit 2'', for example, a first air inlet through hole 282'' serving as part of an air inlet channel, a second air exhaust through hole 292'' serving as part of an air exhaust channel, a first air inlet flow hole 262'' serving as part of an inlet channel, and a first exhaust flow hole 272'' serving as an exhaust channel.
[0213] Similar to the third embodiment, Figure 30-33B The ground electrode 20'' may further include a first gas path channel 205'' formed inside the single-piece body 200'', which is a vertical flow channel intersecting with the first air inlet through-hole. The ground electrode 20'' may further include a second gas path channel 206'' formed inside the single-piece body 200'', which is a vertical flow channel intersecting with the first exhaust through-hole. The ground electrode 20'' may further include a cooling flow channel 204'' formed inside the single-piece body 200'', which includes a plurality of parallel vertical flow channels formed inside the single-piece body and a horizontal connecting structure 2042'' at the top and bottom and connecting with the vertical flow channels, the first vertical flow channel among the plurality of parallel vertical flow channels intersecting with the first air inlet through-hole, and the second vertical flow channel intersecting with the first row of flow holes.
[0214] However, unlike the third embodiment, Figure 30-33B , the communicating structure shown in the fourth embodiment is located on the surface (such as the first surface) of the one-piece body, so that the flow channel in the fourth embodiment can be conventionally sealed with screws.
[0215] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and the associated alignment and positioning structure as described in the first or second embodiment may not be provided in the fourth embodiment.
[0216] In addition, a plurality of first bolt holes 207'' may be formed in the ground electrode 20''.
[0217] The first end cap (end ground electrode) 22'" may be formed similarly to the ground electrode 20'", but differs in that the first surface 221'" of the ground electrode 22'" is not provided with a reaction zone and related features.
[0218] Combined with reference Figure 30-33B The first end cap 22'" may include a reaction zone 2200'" formed in a second surface 222'" of the one-piece body 220'". The ground electrode 22'" may 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 located at the first end 2223"' and a second curve located at the second end 2224"'. Specifically, the first curve may be a first parabola 2225"', and the second curve may be a second parabola 2226"'. Similarly, the first end cover 22"' may also include an air inlet micropore 2221"' and an air outlet pore 2222"' located within the envelope of each planar groove 2220"', the air inlet micropore 2221"' being arranged adjacent to the first end 2223"', and the air outlet pore 2222"' being arranged adjacent to the second end 2224"'. The air inlet micropore 2221"' is approximately arranged at the focus of the first parabola. More specifically, the center of the air inlet micropore 2521"' may approximately coincide with the focus of the first parabola. Similarly, the air outlet hole 2222''' is substantially disposed at the focus of the second parabola. More specifically, the center of the air outlet hole 2222''' may substantially coincide with the focus of the second parabola.
[0220] The structure and size of the air inlet micropores and air inlet holes of the first end cover 22'' can refer to the ground electrode 20'', but the air inlet micropores and air inlet holes of the first end cover 22'' of the fourth embodiment are arranged in the second surface.
[0221] Combined with reference Figure 30-33BThe reaction zone 2200" is substantially rectangular, and the single-piece body 220" of the first end cap 22" further defines a reaction zone surrounding groove 2229" in the second surface 222" that defines the reaction zone 2200".
[0222] With reference to Figure 30-33B Like the ground electrode 20", the first end cap 22" further includes 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" in the reaction zone 2200 that symmetrically connects a planar recess 2210" (intermediate planar recess) at the first end 2213". The shunt groove 2218" extends to and only to a gas inlet micro-hole 2211" in the planar recess.
[0223] With reference to Figure 30-33B Preferably, all of the planar recesses 2520" in the second surface are closed except for the shunt groove 2218" described above.

[0228] Since the fluid distribution structure is formed inside the single-piece body, the annular seal and the associated alignment and positioning structure as described in the first or second embodiment may not be provided in the fourth embodiment.
[0229] In addition, a plurality of first bolt holes 227'' may be formed in the first end cover 22''.
[0230] Unlike the first or second embodiment, in the fourth embodiment, the through hole for fluid supply (discharge) is circular.
[0231] Furthermore, it will be appreciated that although a ground electrode at one end is described above, a ground electrode at the other end that is symmetrical is contemplated.
[0232] The following reference Figure 30-33B , describing the high-voltage discharge assembly 21'' of the ozone generating unit 2'' of the fourth embodiment.
[0233] like Figure 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 further include an elastic pad assembly.

The joint portion can be accommodated in a limiting groove.
[0235] The elastic frame member 210'' may have a frame structure that defines a pressure balance zone located on the back side of the pair of dielectric plates 216''. Similar to the third embodiment, the elastic frame member also includes a second pressure balance structure, including a pressure balance groove, which has an opening. The pressure balance groove extends beyond the envelope of the dielectric plate 216'', thereby connecting to the diversion groove outside the dielectric plate to receive the reaction gas from the diversion groove of the ground electrode and divert it to the pressure balance zone, which can be a hollow portion formed in the elastic frame member. A number of laterally extending balance channels will be set in the pressure balance zone, which are provided by the elastic pad assembly.
[0236] like Figure 30-33BAs shown, the elastic pad assembly includes an elastic pad 212'' and a heat conducting plate 214'' located on both side surfaces of the elastic pad. The heat conducting plate 214'' is preferably bonded to the elastic pad 212''.

Specifically, the elastic frame member 210'' includes a plurality of positioning bosses (not shown).

[0239] like Figure 30-33B As shown, the elastic pad assembly may further include a notch for allowing the elastic contact piece to pass through. The shape of the balancing groove, except for the notch, is substantially the same as that of the corresponding planar groove.
[0240] like Figure 30-33B As shown, a plurality of balancing grooves 2121 ″′ have communicating channels 2128 ″′ between the elastic ridges 2122 ″′, and gap areas 2123 ″′ are formed between the elastic ridges.
[0241] Similar to the first, second and third embodiments, the dielectric plate 216'' has a creeping discharge suppression structure. In addition, as previously described, the elastic pad assembly forms a gap with the frame structure of the frame member 210'', thereby forming a further creeping discharge suppression structure.
[0242] Ruru Figure 30-33B As shown, the elastic frame member 210'' of the high-voltage discharge assembly 21'' may include a second air inlet through-hole, a second air outlet through-hole, a second air inlet flow hole and a second row of flow holes located outside the dielectric plate 216'', which are formed by sealing rings. These sealing rings can engage the corresponding surrounding grooves of the ground electrode and the adjacent ground electrode.
[0243] Similarly to the third embodiment, the elastic frame member in the fourth embodiment does not constitute a part of the thickness of the ozone generating unit, i.e. the relevant part of the thickness is constituted by the ground electrode, whereby the high voltage discharge assembly can be accommodated in the recessed reaction zone. Correspondingly, in contrast to the first or second embodiment, the fourth embodiment does not have a spacer.
[0244] The elastic frame member of the high voltage discharge assembly can further comprise a second bolt through hole (not shown).
[0245] The elastic frame member 210" of the high voltage discharge assembly 21"' of the fourth embodiment can further have a surrounding ridge, which can be accommodated in the surrounding groove of the reaction zone to provide a seal.
[0246] Similarly to the third embodiment, the ground electrode and the high voltage discharge assembly of the fourth embodiment are mounted alternately, which can be done according to the conventional stacking and can be tightened by the bolt tightening mechanism 24"'.
[0247] The fluid supply (discharge) structure and the distribution structure of the fourth embodiment are similar to those of the third embodiment and will not be described here again.
[0248] As mentioned before, in particular with reference to Figure 1F and Figure 1G The plate-type ozone generating unit 2 of the ozone generator 10 can be connected to the electrical elements by means of a wiring strip (or wiring terminal).
[0249] As mentioned before, the ozone generating unit 2 can comprise a plurality of stacked ground electrodes, one or more high voltage discharge assemblies arranged between the plurality of stacked ground electrodes. Correspondingly, the one or more high voltage discharge assemblies can be electrically connected to the high voltage wiring strip 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 figures, the high voltage wiring strip 3 (or high voltage wiring terminal) can comprise or be connected to one or more parallel arranged high voltage fuse devices electrically connected to the plurality of high voltage discharge devices. The electrical connections mentioned above can be realized, for example, by means of plug-in connectors (not shown).

[0275] The first group of embodiments relates to Figures 1A to 33B , and relates to a novel ground electrode structure.
[0276] In some techniques known to the inventor, it is proposed to realize the generation of ozone gas by a planar groove as the reaction space.
[0277] In further techniques 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-groove to provide more reaction gas to the planar micro-groove and to provide a higher flow of generated gas, for which an open end is formed at both ends of the planar groove, and a long hole or long groove is formed in the recessed area to form a long gas cavity in the recessed area of the stacked ground electrodes.
[0278] In another technique 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 electrodes. And based on the "desire" to improve the flow of reaction gas, in this technique a plurality of gas inlet and outlet through-holes are used 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 and outlet through-holes as a smooth diffusion structure.
[0279] However, the inventor found that in the embodiment 1.1 of the invention, by significantly reducing the size of the gas inlet hole connected to the planar groove to a gas inlet micro-hole (the size of the gas outlet hole can have a higher margin) and allowing the gas inlet micro-hole to be adjacent to the curved end, the ozone reaction efficiency can be significantly improved, so that the ozone generation unit has a significantly higher yield per unit volume (unit weight). Compared with the two aforementioned techniques based on planar grooves, the gas inlet micro-hole and the structure of the curved end combined with it in the embodiment of the invention intentionally reduces the size of the flow inlet, to some extent against the intuition of expanding the flow inlet as much as possible to improve the flow of reaction gas and thus improve the gas production efficiency; and also saves the specially arranged diffusion structure, achieving unexpected results. Accordingly, the embodiment 1.1 of the invention further improves the gas production efficiency by combining the curved end structure with the gas outlet hole, but the inventor realizes that the design of the gas outlet hole size can have a higher margin (as described in embodiment 1.5), rather than necessarily reducing it to a micro-hole.
[0280] Further, more surprisingly, it is found that embodiments 1.2 and 1.3 of the invention can more optimally improve the gas production efficiency by providing smooth gas flow along the curve by setting the gas inlet micro-hole (and preferably also the gas outlet hole) at the focal point of the parabolic curve, especially coinciding with the focal point.
[0281] Further, embodiments 1.4 and 1.5 of the invention 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] Furthermore, the gas inlet micro-holes (and gas outlet holes) of the embodiments of the present application are combined with the curved end structure, which makes the reaction zone not necessarily a recessed zone or formed in a recessed zone, which makes the compact structure of the ozone generation unit and its discharge chamber possible, and also makes the thin ground electrode possible, such as the thin ground electrode described in the 8th group of embodiments.
[0283] Furthermore, the gas inlet micro-holes of the embodiments of the present application also allow the ground electrode itself to form an efficient and compact reaction gas distribution structure and cold zone fluid distribution structure and associated structures (as described in embodiments 1.9 to 1.14), and also possibly form advantageous applications by combining the gas inlet micro-holes with these structures, such as novel fluid distribution structures and related sealing, positioning structures.
[0284] Furthermore, the gas inlet micro-hole structure of the embodiments of the present application makes novel discharge chamber related components, structures or parts possible, such as novel ground electrodes, high-voltage discharge assemblies and related pressure balance structures, heat balance structures, surface discharge suppression structures, etc.

[0306] The fourth group of embodiments involves Figures 1A to 33B , and relates to a surface discharge suppression structure of a discharge chamber of an ozone generating unit.
[0307] In the related art of plate-type ozone generators, suppressing surface (dielectric plate) discharge is a practical problem that is desired to be solved but has long existed. As an explanation and not a limitation, ozone generators usually use discharge to generate low-temperature plasma gas to achieve ozone generation, thereby generating discharge between the dielectric plate and the ground electrode, and inevitably generating other discharges along the side of the dielectric plate, the latter of which is sometimes unfavorable. For example, in plate-type ozone generating units, especially in high-voltage discharge components within the discharge chamber, elastic (body) materials or non-rigid / metal materials are usually used. The above-mentioned unfavorable surface discharge may cause aging, carbonization, or even fire of the relevant materials, adversely affecting the continuous working time of the ozone generating unit and even affecting the life of the ozone generating unit. In addition, certain unfavorable surface discharges may also lead to a decrease in gas production efficiency.
[0308] In the related art of plate-type ozone generators known to the inventors, it is proposed to form excessively rounded portions at the corners of the rigid ground electrode to slow down the accumulation of creeping discharge at the corners where creeping discharge is most likely to accumulate, causing aging of the non-metallic materials of the high-voltage discharge unit or adversely affecting the gas production yield.
[0309] In contrast, in the fourth set of embodiments of the present invention, by forming a creeping discharge suppression device on the back side of the dielectric plate, possible creeping discharge on the back side is comprehensively suppressed, not just at the corners. This improves the continuous operating time and lifespan of the ozone generating unit, while preventing undesirable creeping discharge from adversely affecting gas production efficiency. This is achieved, for example, by providing an uncoated edge region on the back side of the dielectric plate separated from the frame structure (in combination with a conductive plate covering the elastic pad), as described in Example 4.1, or by floating and gap-mounting the elastic pad assembly relative to the elastic frame member (in combination with a heat-conducting plate substantially separating the conductive coating region and the elastic pad), as described in Example 4.5, or by a combination of both and / or further in combination with other features.
[0310] Furthermore, those skilled in the art will appreciate that the methods and steps described in accordance with the embodiments of the present disclosure can be applied to the apparatuses and devices described in accordance with the embodiments of the present disclosure to form new apparatus and device embodiments, without conflict. Conversely, the methods, procedures, and steps described for the apparatuses and devices described in accordance with the embodiments of the present disclosure can also be incorporated into the methods of the embodiments of the present disclosure to form new method embodiments, without conflict.
[0311] While the exemplary apparatus, systems, and methods of the present invention have been specifically shown and described with reference to the foregoing embodiments, these are merely illustrative of the best modes for implementing the present systems and methods. Those skilled in the art will appreciate that various modifications may be made to the embodiments of the systems and methods described herein when implementing the present systems and / or methods without departing from the spirit and scope of the present invention as defined in the appended claims.
