[0040] In the description of the embodiments in this application, the orientation or positional relationship of "inner," "outer," "head," and "tail" refers to the orientation or positional relationship of the ion generator during normal use. For example, Figure 2 The orientation or positional relationship shown. The terms "first / second" are merely to distinguish different objects and do not indicate that they are the same or related. It should be understood that these orientation terms are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] One embodiment of this application provides an ion generating device; please refer to [link to relevant documentation]. Figures 1 to 4 The ion generating device includes a shell 1, a first electrode 2, a second electrode 3, and a gas supply pipe 4. The shell 1 is used for circulating water.

[0042] Specifically, the casing 1 has an inlet 1b, an outlet 1c, and a flow channel 1a communicating with the inlet 1b and the outlet 1c. Water can flow into the flow channel 1a from the inlet 1b and out of the flow channel 1a from the outlet 1c.

[0043] The second electrode 3 is spaced apart from the first electrode 2, and the space between the first electrode 2 and the second electrode 3 is an ionization channel 2a. The ionization channel 2a is connected to the shell 1, and a potential difference is formed between the first electrode 2 and the second electrode 3 to ionize the airflow in the ionization channel 2a. For example, the first electrode 2 is a low-voltage electrode, conductively connected to the low-voltage end of a high-voltage power supply or grounded. The second electrode 3 is a high-voltage electrode, conductively connected to the high-voltage end of a high-voltage power supply, which can be a high-frequency alternating current with a voltage between 1kV and 30kV. After gas is introduced into the ionization channel 2a, the first electrode 2 and the second electrode 3 discharge under the action of the high-voltage power supply, ionizing the gas flowing through the ionization channel 2a and generating high-energy electrons, hydroxyl groups, free radicals, ozone, hydrogen peroxide, and other active components. After ionization, the gas containing the above-mentioned active components flows into the flow channel 1a along the ionization channel 2a and mixes with the water flow.

[0044] The gas supply pipe 4 is electrically connected to the second electrode 3. The second electrode 3 is connected to the high-voltage terminal of an external high-voltage power supply through the gas supply pipe 4, and the gas supply pipe 4 has an outlet 4a that communicates with the ionization gas channel 2a. That is to say, a gas supply channel 4c that communicates with the outlet 4a is formed inside the gas supply pipe 4, and external gas flows into the ionization gas channel 2a through the outlet 4a along the gas supply channel 4c.

[0045] Specifically, in one embodiment, the gas supply pipe 4 is located outside the ionization gas channel 2a. The gas supply pipe 4 is a conductor and is electrically connected to the high-voltage end of the high-voltage power supply. The tail end of the gas supply pipe 4 is electrically connected to the head end of the second electrode 3. The gas outlet 4a is located outside the ionization gas channel 2a and communicates with the opening at the head end of the ionization gas channel 2a. That is, the gas supply pipe 4 is located outside the ionization gas channel 2a, and while supplying gas, the gas supply pipe 4 also acts as a conductor to supply power to the second electrode 3. In another embodiment, a portion of the gas supply pipe 4 extends into the ionization gas channel 2a. The gas supply pipe 4 is a conductor and is electrically connected to the high-voltage end of the high-voltage power supply. The portion of the gas supply pipe 4 extending into the ionization gas channel 2a is electrically connected to the second electrode 3, and the portion of the gas supply pipe 4 extending into the ionization gas channel 2a forms a gas outlet 4a communicating with the ionization gas channel 2a.

[0046] The ion generating device provided in this application embodiment has, on the one hand, a gas supply pipe 4 with an outlet 4a connected to the ionization gas channel 2a to provide airflow to the ionization gas channel 2a; on the other hand, the gas supply pipe 4 itself is a conductive wire and is conductively connected to the second electrode 3. That is, the gas supply pipe 4 has the dual function of conducting electricity and supplying gas, so that the second electrode 3 does not need to be provided with an additional wire to connect to an external high-voltage power supply. The overall structure of the ion generating device is more compact and the overall size is smaller.

[0047] The material of the casing 1 includes, but is not limited to, lightweight materials with poor conductivity such as plastics, for example, polyethylene, polypropylene, and polyvinyl chloride. Plastics are lightweight, which can reduce the overall structural weight. At the same time, plastics have high insulation properties, which can prevent the internal electrodes of the casing 1 from conducting electricity to the casing 1 and causing electric shock hazards to personnel, thus improving structural safety.

[0048] The materials of the first electrode 2, the second electrode 3, and the gas supply pipe 4 include, but are not limited to, metal materials with good electrical conductivity, such as copper, aluminum, and other alloy materials.

[0049] The method of conductive connection between the air supply pipe 4 and the second electrode 3 is not limited; for example, welding, threaded connection, or snap-fit ​​can be used. In one embodiment, please refer to... Figure 1 , Figure 4 and Figure 6 The second electrode 3 and the gas supply pipe 4 are integrally formed. The integrally formed structure can make the overall strength of the gas supply pipe 4 and the second electrode 3 better, the resistance of their conductive connection is small, the thermal resistance loss of the high voltage power supply is lower, and the ionization efficiency of the ion generator is higher.

[0050] As an example, in one embodiment, please refer to Figure 1 , Figure 4 and Figure 6 The air supply pipe 4 is a hollow tubular structure, and the second electrode 3 is a solid columnar structure. The air supply pipe 4 and the second electrode 3 are coaxially arranged. The end face of one axial end of the air supply pipe 4 is connected to the end face of one axial end of the second electrode 3. An air supply channel 4c is formed inside the air supply pipe 4. The axial end of the air supply channel 4c away from the second electrode 3 is connected to an external air source. The end of the air supply channel 4c close to the second electrode 3 is connected to the air outlet 4a. The air outlet 4a is formed on the circumferential wall of the part of the air supply pipe 4 that extends into the ionization channel 2a.

[0051] The number of air outlets 4a is unlimited. Multiple air outlets 4a can increase the air supply efficiency of the air supply channel 4c, and the gas can flow more smoothly into the ionization channel 2a.

[0052] In one embodiment, the first electrode 2 includes a conductive electrode and a grounding electrode electrically connected to the conductive electrode. The conductive electrode and the second electrode 3 are spaced apart to form an ionization channel 2a. The grounding electrode is used to be electrically connected to the low-voltage end of a high-voltage power supply or grounded. That is, during operation, a potential difference is generated between the conductive electrode and the second electrode 3 to ionize the airflow located in the ionization channel 2a. The grounding electrode is electrically connected to the conductive electrode on one hand, and externally connected to the low-voltage end of a high-voltage power supply or grounded on the other hand, so as to provide power to the conductive electrode.

[0053] The structure of the first electrode 2 is not limited. As an example, in one embodiment, please refer to... Figure 1 , Figure 4 and Figure 6 The conductive electrode is an electrode tube 21, the second electrode is sleeved in the electrode tube 21, and the electrical electrode is an electrical ring 22, which is arranged around the outer periphery of the electrode tube 21.

[0054] Both the first electrode 2 and the second electrode 3 can be disposed outside or inside the casing 1. In one embodiment, the casing 1 is fitted over the electrode tube 21. That is, both the first electrode 2 and the second electrode 3 are disposed inside the casing 1, and the electrode tube 21 is connected to the low-voltage end of a high-voltage power supply via a connecting ring 22 or directly grounded. On the one hand, disposing of the first electrode 2 and the second electrode 3 inside the casing 1 makes full use of the space inside the casing 1, thereby reducing the overall structural size of the ion generator. On the other hand, since the casing 1 has a flow channel 1a, it can provide heat dissipation for the first electrode 2 and the second electrode 3. The water flowing in the flow channel 1a can carry away the additional heat generated by the first electrode 2 and the second electrode 3 during operation, thereby ensuring that the ion generator operates more reliably.

[0055] As an example, in one embodiment, please refer to Figure 1 , Figure 4 and Figure 6 The contact ring 22 is located at the axial beginning of the electrode tube 21. The gas supply pipe 4 extends from the beginning of the electrode tube 21 into the ionization gas passage 2a. The end face of the contact ring 22 facing the axial end of the electrode tube 21 has a mounting groove 22a, and the tube shell 1 is inserted into the mounting groove 22a. Specifically, the contact ring 22 is an annular plate structure, and the mounting groove 22a is formed on the end face of the contact ring 22. The electrode tube 21 is a tubular structure with openings at both ends along the axial direction. The gas supply pipe 4 passes through the contact ring 22 and extends into the beginning of the electrode tube 21. The outer peripheral wall of the beginning of the tube shell 1 mates with the inner peripheral wall of the mounting groove 22a of the contact ring 22, so that the tube shell 1 is fitted into the mounting groove 22a. With this arrangement, the mounting groove 22a can cover the outer periphery of the tube shell 1, which facilitates the conductive connection of the contact ring 22 to the low-voltage end of the high-voltage power supply or direct grounding.

[0056] In one embodiment, please refer to Figure 1 The contact ring 22 has a wiring structure 221 for connecting external wires. The wiring structure 221 facilitates the electrical connection between the contact ring 22 and the conductor. The structure of the wiring structure 221 is not limited; for example, it can be a terminal block or a terminal hole. As an example, in one embodiment, please refer to... Figure 1 The wiring structure 221 is a wiring hole, which is located on the outer peripheral wall of the contact ring 22. Operators can pass wires through the wiring hole and then tighten them using fixing screws, making wiring convenient and quick.

[0057] To ensure that the casing 1 will not easily detach from the mounting groove 22a and to improve the overall structural reliability, the mounting groove 22a and the casing 1 can be fixed by means of snap-fit, welding, adhesive bonding, or threaded connection. For example, in one embodiment, please refer to... Figures 1 to 3 and Figure 6 The circumferential surface of the mounting groove 22aa forms a limiting groove 22aa, and the outer circumferential surface of the tube shell 1 forms a limiting protrusion 11. The limiting protrusion 11 is located within the limiting groove 22aa and abuts against the groove wall of the limiting groove 22aa. In other words, the tube shell 1 and the mounting groove 22aa are fixed by snap-fit. Compared with threaded connection, the limiting protrusion 11 is set on the outer circumferential wall of the tube shell 1, which will not damage the sealing of the flow channel 1a inside the tube shell 1. At the same time, the structure is simple and easy to fix. Compared with welding and gluing, the tube shell 1 and the first electrode 2 are easy to disassemble, which facilitates the maintenance and replacement of the ion generator and increases the number of times the structural components can be reused.

[0058] In one embodiment, please refer to Figure 4 , Figure 6 and Figure 7 The ion generating device includes a sealing gasket 5. The first end of the tube shell 1 along the axial direction has an opening 1d that communicates with the flow channel 1a of the tube shell 1. The electrode tube 21 extends into the flow channel 1a from the opening 1d. The sealing gasket 5 is sealed and clamped between the surrounding area of ​​the opening 1d and the wall surface of the mounting groove 22a. That is, the opening 1d is the end face of the tube shell 1 facing the contact ring 22. The tail ends of the electrode tube 21, the second electrode 3, and the gas supply pipe 4 can all be axially fitted into the tube shell 1 through the opening 1d, making installation simple. Furthermore, the electrode tube 21, the second electrode 3, and the gas supply pipe 4 are all coaxially arranged with the tube shell 1, resulting in good structural symmetry. To ensure the sealing within the flow channel 1a, the sealing gasket 5 is clamped between the tail end face of the mounting groove 22a facing the opening 1d and the first end face of the opening 1d facing the mounting groove 22a. The material of the sealing gasket 5 includes, but is not limited to, silicone, a material with excellent sealing performance.

[0059] In one embodiment, please refer to Figure 4 and Figure 6 The ion generator includes a gas outlet 6 sleeved outside the first electrode 2, with a portion of the gas outlet 6 extending into the shell 1. The shell 1 has a flow channel 1a. When the gas outlet 6 is placed in the shell 1, the gas flowing out of the gas outlet 6 enters the flow channel 1a with a larger flow cross-section from the ionization gas channel 2a with a smaller flow cross-section. Turbulence will be generated at the outlet of the gas outlet 6, and the gas and liquid phases will converge at the outlet of the gas outlet 6. The gas pressure and velocity of the gas from the gas outlet 6 will decrease rapidly. Under the combined action of rapid pressure release and turbulent kinetic energy, a large number of microbubbles will be generated at the outlet of the gas outlet 6. Microbubbles are beneficial for carrying active ingredients. Microbubbles will break under the action of turbulence and pressure difference, and the broken bubbles will aggravate the disturbance of the water liquid around the bubbles, thereby improving the mixing effect of the ionized gas with active ingredients and the water liquid.

[0060] In one embodiment, please refer to Figure 4 and Figure 6 The outlet nozzle 6 includes a gas-gathering pipe section 61 connected to the tail end of the ionization gas channel 2a. The cross-sectional area of ​​the gas-gathering pipe section 61 gradually decreases from near the ionization gas channel 2a to far away from it. Specifically, the outlet nozzle 6 connects the ionization gas channel 2a and the flow channel 1a. The cross-sectional area of ​​the ionization gas channel 2a is equal at any position. After the airflow in the ionization gas channel 2a flows through the gas-gathering pipe section 61, the cross-sectional area gradually decreases, and the airflow velocity and pressure gradually increase. When the airflow flows into the flow channel 1a from the tail end of the gas-gathering pipe section 61, the turbulent kinetic energy generated at the outlet of the gas-gathering pipe section 61 is greater and the gas pressure is greater due to the faster gas velocity. The relative pressure difference after the pressure of the gas flowing into the flow channel 1a is also greater. Therefore, the gas movement at the outlet of the gas-gathering pipe section 61 is more intense, thereby generating more microbubbles and further improving the water-air mixing effect.

[0061] The material of the air outlet 6 is not limited; for example, it can be made of plastic materials such as polyethylene, polypropylene, and polyvinyl chloride. Plastic materials are lighter, which can reduce the overall structural weight. At the same time, plastic has high insulation properties, which can prevent the internal electrodes of the tube shell 1 from conducting electricity to the tube shell 1 and causing electric shock hazards to personnel, thus improving structural safety.

[0062] In one embodiment, please refer to Figure 4 and Figure 6 The air outlet 6 includes an air outlet section 62 connected to the tail end of the air-gathering pipe section 61. The cross-sectional area of ​​the flow passage at any position in the air outlet section 62 is equal, but the cross-sectional area of ​​the flow passage at any position in the air outlet section 62 is smaller than the minimum cross-sectional area of ​​the air-gathering pipe section 61. The airflow flows into the air outlet section 62 along the air-gathering pipe section 61. The tail end of the air outlet section 62 is connected to the flow channel 1a. Because the airflow accelerated by the air-gathering pipe section 61 flows into the flow channel 1a along the air outlet section 62, the airflow velocity in the air outlet section 62 is faster and the airflow pressure is greater than that in the air-gathering pipe section 61. Therefore, the pressure difference after pressure release at the tail end outlet of the air outlet section 62 is also greater, the gas movement at the tail end outlet of the air outlet section 62 is more intense, more microbubbles are generated, and the mixing effect of the airflow with active ingredients and water is better.

[0063] As an example, in one embodiment, please refer to Figure 4 and Figure 6 The gas-gathering pipe section 61 is a hollow tubular structure with a conical circumferential wall. The conical structure is easy to process, and the cross-sectional area of ​​the flow path changes uniformly. In one embodiment, the gas-exit pipe section 62 is a hollow tubular structure with a cylindrical circumferential wall.

[0064] In one embodiment, please refer to Figure 4 and Figure 6The flow channel 1a includes a steady flow section 1aa and an outlet section 1ab. The first electrode 2 is located in the steady flow section 1aa, and the inlet 1b is located in the steady flow section 1aa. The outlet section 1ab connects the steady flow section 1aa and the outlet 1c. The air outlet pipe section 62 extends into the outlet section 1ab. The water flow in the steady flow section 1aa can cool and dissipate heat for the first electrode 2 during operation. The outlet 1c is located in the outlet section 1ab, and the tail end of the air outlet pipe section 62 is close to the outlet 1c to mix water and air in the outlet section 1ab.

[0065] In one embodiment, please refer to Figure 4 and Figure 6 The steady flow section 1aa includes a straight section 1aaa and a confluence section 1aab. The confluence section 1aab connects the straight section 1aaa and the outlet section 1ab. The cross-sectional area of ​​the straight section 1aaa is larger than that of the outlet section 1ab. The cross-sectional area of ​​the confluence section 1aab gradually decreases from the straight section 1aaa to the outlet section 1ab. Specifically, the gas gathering pipe section 61 is located at the confluence section 1aab, the first end of the gas outlet pipe section 62 is located at the confluence section 1aab, and the tail end of the gas outlet pipe section 62 extends into the outlet section 1ab. The cross-sectional area of ​​the straight section 1aaa is equal at any position. Similarly, when the gas outlet pipe section 62 does not extend into the outlet section 1ab, the cross-sectional area of ​​the outlet section 1ab is also equal at any position. As the water flow in the straight section 1aaa gradually decreases in cross-sectional area after passing through the confluence section 1aab, the flow velocity gradually increases. When the water flows from the confluence section 1aab into the outflow section 1ab, the flow velocity in the outflow section 1ab is greater than that in the confluence section 1aab. At the same time, the tail end of the gas outlet section 62 extends into the outflow section 1ab. When the water flows past the tail end outlet of the gas outlet section 62, the faster-flowing and higher-pressure gas and the faster-flowing and higher-pressure water converge at the tail end outlet of the gas outlet section 62. The turbulence formed by the gas-liquid two-phase convergence is more intense, and the relative pressure difference after the gas and liquid are released is greater. Under the combined action of greater pressure release and more intense turbulence, more tiny bubbles are generated at the tail end outlet of the gas outlet section 62, further improving the water-gas mixing effect.

[0066] As an example, in one embodiment, please refer to Figure 4 and Figure 6 The confluence section 1aab is a hollow tubular structure with a conical circumferential wall. The conical structure is easy to process, and the cross-sectional area of ​​the flow path changes uniformly. In one embodiment, the straight section 1aaa is a hollow tubular structure with a cylindrical circumferential wall, and / or, the outflow section 1ab is a hollow tubular structure with a cylindrical circumferential wall.

[0067] In one embodiment, please refer to Figures 4 to 6The ion generating device includes a support member 8 located within a flow channel 1a. One end of the support member 8 is connected to the circumferential surface of the flow channel 1a, and the other end of the support member 8, away from the circumferential surface of the flow channel 1a, can abut against the first electrode 2. The support member 8 is used to support the first electrode 2 located within the flow channel 1a. The support member 8 ensures that the first electrode 2 will not collide with the inner wall of the casing 1, and the first electrode 2 can be stably fitted within the flow channel 1a, making it less prone to shaking and displacement, thus improving the overall reliability of the device.

[0068] The connection method between the support member 8 and the shell 1 is not limited; for example, welding, threaded connection, or snap-fit ​​can be used. As an example, in one embodiment, please refer to... Figures 4 to 6 The support member 8 and the shell 1 are integrally formed. The integrally formed structure of the support member 8 and the shell 1 has higher overall strength. The support member 8 can enhance the structural strength of the shell 1, and the shell 1 is not easily deformed.

[0069] In one embodiment, please refer to Figures 4 to 6 Multiple support members 8 are arranged circumferentially along the flow channel 1a to define support spaces 8a. The first electrode 2 is located within the support space 8a, and the area between two adjacent support members 8 is a stable flow zone 8b for water flow. On the one hand, the support space 8a can fix the first electrode 2 to the axial region of the flow channel 1a, and the spatial distribution of the flow cross-section at any position in the flow channel 1a is relatively uniform. On the other hand, the multiple support members 8 divide the flow channel 1a into multiple stable flow zones 8b, which can guide the flow, making the water flow more smoothly within the stable flow zone 8b.

[0070] As an example, in one embodiment, please refer to Figures 4 to 6 The support member 8 is a strip-shaped plate structure extending along the water flow direction. The support member 8 extends from the straight section 1aaa to the confluence section 1aab. Within the confluence section 1aab, the end of the support member 8 furthest from the casing 1 abuts against the outer peripheral wall of the gas-gathering pipe section 61 of the gas outlet 6. Within the straight section 1aaa, the end of the support member 8 furthest from the casing 1 can abut against the outer peripheral wall of the first electrode 2.

[0071] With this configuration, the stabilizing zone 8b extends further along the axial direction, and the support member 8 can abut against both the outlet nozzle 6 and the first electrode 2, providing better support. At the same time, since the outer peripheral wall of the gas gathering pipe section 61 is a conical surface, the support member 8 abuts against the conical surface of the outer peripheral wall of the gas gathering pipe section 61. After abutting, it can ensure that the outlet nozzle 6 will not slide radially relative to the pipe shell 1, resulting in high reliability.

[0072] In one embodiment, the air outlet 6, the first electrode 2, and the tube shell 1 are arranged coaxially. The coaxial arrangement provides good alignment and a more uniform spatial distribution of the flow cross section at any position within the flow channel 1a.

[0073] In one embodiment, please refer to Figures 4 to 6 The outlet 1c is formed at the tail end face of the outflow section 1ab along the direction of water flow, and the inlet 1b is formed on the circumferential wall of the straight section 1aaa. The first end of the support member 8 is located on the side of the inlet 1b closest to the outlet 1c. That is to say, the extension length of the support member 8 within the straight section 1aaa does not interfere with the inlet 1b, ensuring smooth water flow. The inlet 1b is located on the circumferential wall of the straight section 1aaa, providing more space for pipe connection and preventing interference with the air supply pipe 4 located at one end of the axial direction.

[0074] As an example, in one embodiment, please refer to Figures 4 to 6 The ion generator includes a pipe connector 91 connected to the inlet 1b, and the cross-sectional area of ​​the pipe connector 91 is larger than that of the outlet 1c. In other words, the cross-sectional area of ​​the inlet 1b is larger than that of the outlet 1c. This configuration ensures that the inlet flow rate of the inlet 1b is greater than the outlet flow rate of the outlet 1c. This allows the flow channel 1a to remain filled with water during operation, preventing vacuum or air intake within the flow channel 1a. This ensures a continuous water flow within the flow channel 1a, reliably carrying away the heat generated during the ionization process of the first electrode 2 and the second electrode 3, and preventing overheating of the first electrode 2 or the second electrode 3 that could burn out the casing 1 and cause a short circuit in the outlet 6.

[0075] In one embodiment, please refer to Figure 4 and Figure 6 The circumferential surface of the gas-gathering pipe section 61 has multiple limiting ribs 611, which are arranged at intervals along the circumference to define a limiting space 611a. The tail end of the second electrode 3 extends into the limiting space 611a along the axial direction and abuts against the limiting ribs 611. The limiting ribs 611 have good support properties, ensuring that the tail end of the second electrode 3 does not contact the first electrode 2 and cause a short circuit, thus ensuring the overall reliability of the device. At the same time, the limiting ribs 611 can also strengthen the structural strength of the gas outlet 6, ensuring that the overall structure of the gas-gathering pipe section 61 is not easily deformed.

[0076] As an example, in one embodiment, please refer to Figure 4 and Figure 6 The tail end of the second electrode 3 is a conical surface, and the limiting rib 611 abuts against the conical surface of the tail end of the second electrode 3. The conical surface abutment ensures that the second electrode 3 will not slide radially after abutment, resulting in high reliability. In one embodiment, the second electrode 3 is coaxially arranged relative to the first electrode 2. The coaxial arrangement provides good alignment, and the spatial distribution of the flow cross-section is uniform at any position within the ionization gas channel 2a.

[0077] In one embodiment, please refer to Figure 1 , Figure 4 , Figure 6 and Figure 7The ion generating device includes an end cap 7, a first electrode 2 forming a cavity, a second electrode 3 located within the cavity, and a first end opening 2b communicating with the cavity. The end cap 7 seals and closes the first end opening 2b of the first electrode 2. That is, the first electrode 2 has openings at both ends along the axial direction, and the ionization gas channel 2a connects the first end opening 2b and the tail end opening of the first electrode 2 along the axial direction. Specifically, the first end opening 2b of the first electrode 2 is located on the contact ring 22, and the tail ends of the second electrode 3 and the gas supply pipe 4 extend into the ionization gas channel 2a along the first end opening 2b of the first electrode 2. The end cap 7 has an axially extending vent hole, and the end cap 7 is fitted onto the outer peripheral wall of the gas supply pipe 4 through the vent hole, with the tail end face of the end cap 7 abutting against the first end face of the contact ring 22 to seal and close the first end opening 2b on the contact ring 22.

[0078] The sealing method between the end cap 7 and the first electrode 2 includes bonding with sealant or sealing with a sealing structure. For example, in one embodiment, please refer to... Figure 7 The ion generating device includes a sealing ring 90. A stepped surface 4b is formed on the outer periphery of the portion of the gas supply pipe 4 located within the ionization gas passage 2a. The sealing ring 90 is sealed and clamped between the stepped surface 4b and the end cap 7. The stepped surface 4b clamps the sealing ring 90 tightly against the tail end face of the end cap 7, preventing gas flow within the ionization gas passage 2a from leaking from the opening 2b at the first end of the first electrode 2.

[0079] In one embodiment, please refer to Figure 1 and Figure 6 A support post 222 is formed on the surface of the contact ring 22 away from the outer casing, and a screw hole 222a for fixing the ion generating device is formed within the support post 222. Specifically, the support post 222 extends axially away from the contact ring 22, and the screw hole 222a is formed on the axial end face of the support post 222 away from the contact ring 22. The ion generating device can be conveniently fixed by connecting the screw hole 222a within the support post 222.

[0080] In one embodiment, please refer to Figure 1 and Figure 6 There are multiple support pillars 222, which are arranged at intervals along the circumference of the grounding ring 22. This ensures that the support pillars 222 are evenly distributed on the grounding ring 22, resulting in a more stable fixation.

[0081] In one embodiment, please refer to Figure 1 and Figure 6The end cap 7 has an assembly groove 7a on its axial end face facing the tube shell 1, which is adapted to fit the support column 222. A connecting hole 7aa is formed in the assembly groove 7a. The support column 222 is fitted into the assembly groove 7a, and the connecting hole 7aa communicates with the screw hole 222a. On the one hand, the support column 222 fitted into the assembly groove 7a can restrict the end cap 7 from rotating circumferentially along the tube shell 1. On the other hand, the end cap 7 covers the support column 222, which can prevent the support column 222 from being damaged by impact, thus preventing it from being fixed. The structure has high reliability.

[0082] The end cap 7 can be made of plastic, which has good insulation properties to prevent personnel from accidentally touching the contact ring 22 and causing electric shock. At the same time, the outer surface of the contact ring 22 is provided with an insulating coating, which can further improve safety.

[0083] In one embodiment, please refer to Figures 4 to 7 The ion generating device includes an insulating tube 92, a first electrode 2 sleeved outside the insulating tube 92, and a second electrode 3 sleeved inside the insulating tube 92 without contacting it. In other words, the insulating tube 92 is positioned between the first electrode 2 and the second electrode 3 to prevent the second electrode 3, which is conductively connected to the high-voltage end of the high-voltage power supply, from directly contacting the first electrode 2, which is conductively connected to the low-voltage end of the high-voltage power supply or directly grounded, thus preventing the safety hazard of short circuits and damage to electrical equipment. Specifically, the insulating tube 92 is open at both ends along the axial direction and sleeved on the inner peripheral wall of the electrode tube 21 of the first electrode 2. The first end of the gas-gathering tube section 61 of the gas outlet 6 is sleeved on the outer peripheral wall of the insulating tube 92, and the axial first end face of the gas-gathering tube section 61 abuts against the electrode tube 21. In one embodiment, the insulating tube 92 is made of a ceramic material with good insulation properties.

Water from the outlet 1c can enter the washing chamber. The garment processing device can be a washing machine, a washer-dryer combo, a dryer, a garment steamer, etc.

The washing tub is located inside the outer tub, the water outlet of the spray pipe is located at the garment loading port of the outer tub, the ion generator is located on the top side of the outer tub, and the water outlet 1c is connected to the spray pipe.

[0086] In one embodiment, the garment processing equipment includes an air pump and a water inlet pipe.

The water inlet pipe is used to connect the garment processing equipment's circulating water circuit or to a connecting water inlet valve or water tank connected to an external water source.
