Description

Technical Field

[0001] The present disclosure relates to the field of plasma processing technology, and in particular to a plasma liquid activation system. Background Art

[0002] Plasma activated liquid is a liquid activated by plasma excitation to form a liquid with active ingredients, also known as low temperature plasma activated liquid. In this process, plasma and liquid solution will produce a series of complex reactions, including the generation of hydroxyl radicals (OH·), singlet oxygen ( 1 O2), superoxide anion (O2 ·- ), hydronium ion (H3O + ), nanoparticles and other active substances, which can kill microorganisms such as bacteria and viruses.

[0003] Through the resonance of electromagnetic fields and mechanical wave energy, or through electric fields and hydrodynamic cavitation effects, sustainable plasma excitation can be achieved with a lower voltage to obtain a plasma activated liquid. However, although the obtained plasma activated liquid has a certain bactericidal and disinfecting ability, it cannot meet the requirements of use scenarios with higher sterilization and disinfection requirements, especially the sterilization and disinfection requirements in medical and other fields.

[0090] Figure 1 FIG. 1 is a schematic structural diagram of a plasma liquid activation system 100 according to some embodiments of the present disclosure. Figure 2A schematic diagram of the internal front structure of a plasma liquid activation system 100 according to some embodiments of the present disclosure is shown. Figure 3 A schematic diagram of the internal upper structure of a plasma liquid activation system 100 according to some embodiments of the present disclosure is shown. Figure 4 A schematic diagram of the back side structure of the plasma liquid activation system 100 according to some embodiments of the present disclosure is shown.

[0091] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments of the present disclosure, a plasma liquid activation system 100 may include a plasma liquid generator 101 and a circulation chamber 102. The plasma liquid generator 101 is used to activate liquid. The circulation chamber 102 is in communication with the plasma liquid generator 101 and is used to deliver the liquid to be activated to the plasma liquid generator 101 and receive the activated liquid from the plasma liquid generator 101 to perform a circulating activation process on the liquid.

[0092] In the plasma liquid activation system 100 of the present disclosure, the activated liquid is then passed through the plasma liquid generator 101, where the concentration of active substances can be further increased. In some embodiments of the plasma liquid activation system 100 of the present disclosure, the circulation chamber 102 is provided, allowing the activated liquid to circulate multiple times, thereby increasing the active substance content and improving the sterilization and disinfection properties of the plasma liquid.

[0093] In some embodiments, the liquid to be activated may include liquid that has never been activated by the plasma liquid generator 101 and will be transported to the plasma liquid generator 101 for activation, and liquid that has been activated by the plasma liquid generator 101 and will be circulated and transported to the plasma liquid generator 101 for activation again.

[0094] In some embodiments, the liquid may include various suitable liquid substances, such as tap water, purified water, mineral water, physiological saline, domestic sewage, milk, beverages, natural water, acidic solutions, alkaline solutions, etc.

[0095] like Figure 4 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a control system 121. The control system 121 is used to control the plasma liquid generator 101 to operate for a predetermined time or a predetermined number of cycles to perform a cyclic activation treatment on the liquid. Those skilled in the art will appreciate that the control system 121 may include a single controller or multiple separate controllers. The controller may be implemented in any suitable form, including but not limited to hardware, firmware, software, or any combination thereof, such as control circuitry, control software, and the like.

[0096] In some embodiments, the predetermined operating time of the plasma liquid generator 101 or the predetermined number of cycles of the liquid to be activated may be pre-inputted into the control system 121 to automate the liquid activation and obtain the desired activated liquid.

[0097] like Figure 1 and Figure 2 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a liquid storage tank 105. The liquid storage tank 105 may be used to store the plasma liquid after cyclic activation. The liquid storage tank 105 may include a liquid storage inlet 1051. The circulation chamber 102 may further include a liquid outlet 1024. The liquid storage inlet 1051 of the liquid storage tank 105 is connected to the liquid outlet 1024 of the circulation chamber 102 to receive the cyclic activated plasma liquid.

[0098] In some embodiments of the present disclosure, the control system 121 may be used to control the inflow and outflow of liquid into and out of the circulation chamber 102 based on the liquid level of the circulation chamber 102 .

[0099] In some embodiments of the present disclosure, the control system 121 may be configured to respond to the liquid level of the circulation chamber 102 being below a circulation chamber low threshold (e.g., Figure 1 The control system 121 may also be configured to, in response to the liquid level of the circulation chamber 102 being higher than a high threshold value (e.g., a high liquid level signal of the circulation chamber detected by the circulation chamber liquid level detection device 104), stop the liquid from flowing out of the circulation chamber 102 (e.g., control the circulation chamber liquid outlet valve 107 to be closed), and start the liquid from flowing into the circulation chamber 102 (e.g., control the circulation chamber liquid inlet valve 109 to be opened). The control system 121 may also be configured to, in response to the liquid level of the circulation chamber 102 being higher than a high threshold value (e.g., a high liquid level signal of the circulation chamber detected by the circulation chamber liquid level detection device 104), stop the liquid from flowing in (e.g., control the circulation chamber liquid inlet valve 109 to be closed), and control the plasma liquid generator 101 to operate for a predetermined time or a predetermined number of cycles to perform a cyclic activation treatment on the liquid.

[0100] In some embodiments of the present disclosure, the control system 121 may also be used to control the inflow and outflow of liquid into and out of the liquid storage tank 105 based on the liquid level of the liquid storage tank 105 .

[0101] In some embodiments of the present disclosure, the control system 121 is configured to respond to the liquid level of the liquid tank 105 being below a liquid tank low threshold (e.g., Figure 1The control system 121 may also be configured to, in response to the liquid level of the liquid tank 105 being higher than a high threshold value (e.g., a high liquid level signal of the liquid tank 105 detected by the liquid level detection device 106), stop the liquid from being fed into the liquid tank 105 (e.g., the control system 121 controls the circulation chamber outlet valve 107 and the liquid tank inlet pump 108 to be closed).

[0102] In some embodiments of the present disclosure, the control system 121 may also be used to control the inflow and outflow of liquid into and out of the circulation chamber 102 based on the liquid level of the liquid storage tank 105 and the liquid level of the circulation chamber 102 .

[0103] In some embodiments of the present disclosure, the control system 121 may be configured to respond to the liquid level of the tank 105 falling below a tank low threshold (e.g., Figure 1 The low liquid level signal of the liquid storage tank 105 detected by the liquid storage tank liquid level detection device 106 in the liquid storage tank 105 is detected), and in response to the liquid level of the circulation chamber 102 being lower than the circulation chamber low threshold (for example, Figure 1 The circulating chamber liquid level detection device 104 detects a low liquid level signal of the circulating chamber 102), and starts the liquid inlet to the circulating chamber 102 (for example, controlling the circulating chamber liquid inlet valve 109 to open).

[0104] In some embodiments, the control system 121 can also be used to start liquid inflow into the circulation chamber 102 in response to the liquid level of the liquid storage tank 105 being lower than the liquid storage tank middle threshold (for example, the middle liquid level signal of the liquid storage tank 105 detected by the liquid storage tank liquid level detection device 106), and in response to the liquid level of the circulation chamber 102 being lower than the circulation chamber low threshold.

[0105] In some embodiments of the present disclosure, the control system 121 may also be configured to respond to the liquid level of the liquid tank 105 being below a liquid tank low threshold (e.g., Figure 1 In some embodiments, the control system 121 may also be configured to respond to the liquid level of the liquid tank 105 being lower than a middle threshold value of the liquid tank (e.g., a middle liquid level signal of the liquid tank 105 detected by the liquid tank liquid level detection device 106), and in response to the liquid level of the circulation chamber 102 being no lower than a low threshold value of the circulation chamber, initiate the discharge of liquid from the circulation chamber 102 (e.g., control the circulation chamber liquid outlet valve 107 and the liquid tank inlet pump 108 to be turned on).

[0106] In some embodiments, when the liquid level of the liquid storage tank 105 is lower than a preset value, for example, lower than the liquid storage tank low threshold or lower than the liquid storage tank middle threshold, the control system 121 will first determine whether there is circulating activated plasma liquid in the circulation chamber 102 (for example, determine whether the liquid level of the circulation chamber 102 is lower than the circulation chamber low threshold). If so (for example, determine that the liquid level of the circulation chamber 102 is not lower than the circulation chamber low threshold), the circulation chamber 102 will be started to discharge liquid (for example, transported to the liquid storage tank 105 or discharged as waste liquid). When the liquid level of the circulation chamber 102 is lower than the circulation chamber low threshold, the control system 121 stops the circulation chamber 102 from discharging liquid and starts the circulation chamber 102 from inlet to prepare the circulating activated plasma liquid again.

[0107] In some embodiments, the liquid level in the liquid storage tank 105 is below a liquid storage tank low threshold, which is a mandatory start-up condition for the plasma liquid activation system 100 to continue processing to obtain the recycled activated plasma liquid. When the liquid level in the liquid storage tank 105 is below the liquid storage tank low threshold, the control system 121 first determines whether the recycled activated plasma liquid is present in the circulation chamber 102 (for example, this determination can be made based on the circulation chamber liquid level detection device 104). If so, the recycled activated plasma liquid is first output (for example, to the liquid storage tank 105 or discharged as waste liquid), and then controls the circulation chamber 102 to begin liquid inflow to prepare the recycled activated plasma liquid again.

[0108] In some embodiments of the present disclosure, the control system 121 can be used to start the flow of liquid from the circulation chamber 102 to the liquid storage tank 105 in response to the plasma liquid generator 101 running for a predetermined time or a predetermined number of cycles, and the activated liquid has been processed to obtain activated liquid (for example, the control system 121 controls the circulation chamber outlet valve 107 and the liquid storage tank inlet pump 108 to be turned on). The control system 121 can also be used to stop the flow of liquid from the circulation chamber 102 to the liquid storage tank 105 in response to the liquid level of the circulation chamber 102 being lower than the circulation chamber low threshold or in response to the liquid level of the liquid storage tank 105 being higher than the liquid storage tank high threshold (for example, the control system 121 controls the circulation chamber outlet valve 107 and the liquid storage tank inlet pump 108 to be turned off).

[0109] In some embodiments of the present disclosure, the control system 121 may also be configured to respond to the quality of the liquid injected into the circulation chamber 102 being lower than a quality threshold (e.g., based on Figure 1 The water quality sensor 111 shown in FIG. 1 detects the water quality of the circulation chamber 102 ), and stops the liquid inlet to the circulation chamber 102 (for example, the control system 121 controls the circulation chamber liquid inlet valve 109 to be closed).

[0110] like Figure 1 and Figure 2As shown, in some embodiments of the present disclosure, the circulation chamber 102 may include a liquid injection inlet 1021, a circulation outlet 1022, and a circulation inlet 1023. The liquid injection inlet 1021 is used to receive liquid input. The circulation outlet 1022 is connected to the inlet of the plasma liquid generator 101 and is used to deliver the liquid to be activated to the plasma liquid generator 101. The circulation inlet 1023 is connected to the outlet of the plasma liquid generator 101 and is used to receive the activated liquid from the plasma liquid generator 101 to perform a circulation activation process on the liquid.

[0111] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a circulation pump 103. The liquid inlet of the circulation pump 103 is connected to the circulation outlet 1022 of the circulation chamber 102, and the liquid outlet is connected to the inlet of the plasma liquid generator 101. The circulation pump 103 is in communication with the control system 121 and is used to pump the liquid to be activated to the plasma liquid generator 101.

[0112] In some embodiments, the control system 121 may be in communication with the plasma liquid generator 101 and the circulation pump 103 to control the plasma liquid generator 101 and the circulation pump 103 to operate for a predetermined time or a predetermined number of cycles to perform a cyclic activation treatment on the liquid.

[0113] In some embodiments, the control system 121 sends an instruction to start the circulation pump 103 and the plasma liquid generator 101 to start running. The liquid in the circulation chamber 102 will be sent to the plasma liquid generator 101 by the circulation pump 103 for activation. The circulation chamber 102 receives the activated liquid from the plasma liquid generator 101, and the cycle repeats in this way. When the predetermined time (for example, 1-5 minutes) or the predetermined number of cycles (for example, the circulation pump 103 pumps a predetermined multiple of the volume of the liquid in the circulation chamber 102) of the control system 121 is reached, the plasma liquid generator 101 and the circulation pump 103 are controlled to stop running, and the circulation process will stop automatically.

[0114] In some embodiments, the control system 121 may first send an instruction to start the circulation pump 103 and then control the plasma liquid generator 101 to start. For example, the plasma liquid generator 101 may be started several seconds after the circulation is started.

[0115] In some embodiments, the circulation pump 103 is used to provide liquid circulation power for the plasma liquid activation system 100, and in particular, to provide the required liquid pressure for the plasma liquid generator 101. Therefore, the maximum pressure of the circulation pump 103 is generally required to be above 1 MPa. In some embodiments, the circulation pump 103 can include a diaphragm pump, a plunger pump, or other liquid pump capable of providing a relatively high pressure.

[0116] like Figure 1 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a circulation chamber liquid level detection device 104 , which is in communication with the control system 121 and is used to detect the liquid level in the circulation chamber 102 .

[0117] like Figure 1 As shown, in some embodiments of the present disclosure, the circulation chamber liquid level detection device 104 may include a circulation chamber high liquid level sensor 1041 and a circulation chamber low liquid level sensor 1042. The circulation chamber high liquid level sensor 1041 is disposed in the circulation chamber 102. The circulation chamber low liquid level sensor 1042 is disposed in the circulation chamber 102 and is located below the circulation chamber high liquid level sensor 1041.

[0118] In some embodiments, the control system 121 is configured to control the flow of liquid into the circulation chamber 102 in response to the liquid level of the circulation chamber 102 detected by the circulation chamber low liquid level sensor 1042 being lower than the circulation chamber low threshold (e.g., a low liquid level signal of the circulation chamber 102 detected by the circulation chamber low liquid level sensor 1042) to restart the circulation activation process for the liquid. The control system 121 is configured to control the circulation chamber 102 to stop flowing liquid in response to the liquid level of the circulation chamber 102 detected by the circulation chamber high liquid level sensor 1041 being higher than the circulation chamber high threshold (e.g., a high liquid level signal of the circulation chamber 102 detected by the circulation chamber high liquid level sensor 1041).

[0119] like Figure 1 and Figure 2 As shown, in some embodiments of the present disclosure, the circulation chamber 102 is slender, such as a slender cylinder, including but not limited to a cylinder, a prism, an elliptical cylinder, etc. The liquid injection inlet 1021 and the circulation inlet 1023 are both located at the upper part of the circulation chamber 102, and the circulation outlet 1022 and the liquid outlet 1024 are both located at the lower part of the circulation chamber 102.

[0120] In some embodiments, the circulation chamber 102 is used to accommodate the total amount of liquid to be circulated by the activated liquid. It is designed to be elongated, narrow, and tall, which helps improve the efficiency and uniformity of the activated liquid circulation. This simple structure, without the need for additional auxiliary equipment, effectively prevents some liquid from being effectively circulated. In some embodiments, the height-to-width ratio of the circulation chamber can be greater than 1. For example, the height-to-width ratio can be any range or value from 1.1-2, 1.5-5, or 2-20.

[0121] like Figure 1 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a liquid tank level detection device 106 , which is in communication with the control system 121 and is used to detect the liquid level in the liquid tank 105 .

[0122] like Figure 1 As shown, in some embodiments of the present disclosure, the liquid tank level detection device 106 may include a liquid tank high liquid level sensor 1061 and a liquid tank low liquid level sensor 1062. The liquid tank high liquid level sensor 1061 is disposed in the liquid tank 105. The liquid tank low liquid level sensor 1062 is disposed in the liquid tank 105 and is located below the liquid tank high liquid level sensor 1061.

[0123] In some embodiments, when the liquid storage tank 105 receives the activated plasma liquid after circulation from the circulation chamber 102, the control system 121 controls the liquid storage tank 105 to stop discharging liquid in response to the liquid level of the liquid storage tank 105 detected by the liquid storage tank high level sensor 1061 being higher than the liquid storage tank high threshold (e.g., the high liquid level signal of the liquid storage tank 105 detected by the liquid storage tank high level sensor 1061). The control system 121 controls the liquid storage tank 105 to stop discharging liquid in response to the liquid level of the liquid storage tank 105 detected by the liquid storage tank low level sensor 1062 being lower than the liquid storage tank low threshold (e.g., controlling the liquid storage tank 105 to stop receiving liquid. When liquid is discharged from the liquid storage tank 105 (e.g., when a user draws water), the low liquid level sensor 1062 detects the low liquid level signal of the liquid storage tank 105).

[0124] In some embodiments, the control system 121 can be configured to initiate liquid inflow into the circulation chamber 102 in response to the liquid level of the liquid tank 105 detected by the liquid tank low level sensor 1062 being lower than a liquid tank low threshold and the liquid level of the circulation chamber 102 detected by the circulation chamber low level detection device 1042 being lower than a circulation chamber low threshold. The control system 121 can also be configured to initiate liquid outflow from the circulation chamber 102 in response to the liquid level of the liquid tank 105 detected by the liquid tank low level sensor 1062 being lower than a liquid tank low threshold and the liquid level of the circulation chamber 102 not being lower than the circulation chamber low threshold.

[0125] In other embodiments of the present disclosure, the liquid tank liquid level detection device 106 may further include a liquid tank mid-level sensor (not shown), which is disposed in the liquid tank 105 and located between the liquid tank high liquid level sensor 1061 and the liquid tank low liquid level sensor 1062. The liquid tank mid-level sensor may be disposed at any position between the liquid tank high liquid level sensor 1061 and the liquid tank low liquid level sensor 1062, for example, in the middle of the liquid tank high liquid level sensor 1061 and the low liquid level sensor 1062, or closer to the liquid tank high liquid level sensor 1061 or closer to the liquid tank low liquid level sensor 1062. The liquid tank mid-level sensor is used to monitor the liquid level of the liquid tank 105 between the high liquid level and the low liquid level.

[0126] In some embodiments, the control system 121 can be configured to initiate liquid inflow into the circulation chamber 102 in response to the liquid level of the liquid tank 105 detected by the liquid level sensor in the liquid tank being lower than a liquid tank medium threshold (e.g., a medium liquid level signal of the liquid tank 105 detected by the liquid level sensor in the liquid tank) and the liquid level of the circulation chamber 102 detected by the circulation chamber low liquid level detection device 1042 being lower than a circulation chamber low threshold. Initiating liquid inflow into the circulation chamber 102 based on the liquid level of the liquid tank 105 being lower than the liquid tank medium threshold can minimize water shortages when a user draws water from the liquid tank 105 or reduce user waiting time.

[0127] In some embodiments, the control system 121 may also be configured to initiate the discharge of liquid from the circulation chamber 102 in response to the liquid level in the liquid storage tank 105 falling below a liquid storage tank middle threshold and the liquid level in the circulation chamber 102 not falling below a circulation chamber low threshold. In this manner, if there is still liquid in the liquid storage tank 105, pre-circulated activated liquid can be added from the circulation chamber 102 to the liquid storage tank 105 to prevent the liquid in the liquid storage tank 105 from being depleted.

[0128] In some embodiments, after the liquid storage tank 105 receives the plasma liquid after circulation activation, the control system 121 can automatically start the liquid discharge action of the liquid storage tank 105 based on the signal of the liquid level of the liquid storage tank low liquid level sensor 1062 being not lower than the liquid storage tank low threshold, for example, when the liquid storage tank outlet valve 114 is open.

[0129] like Figure 1 and Figure 2 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a circulation chamber liquid outlet valve 107 and a liquid storage tank liquid inlet pump 108, which are sequentially arranged on the connecting pipeline between the liquid outlet 1024 of the circulation chamber 102 and the liquid storage inlet 1051 of the liquid storage tank 105, and are communicatively connected to the control system 121.

[0130] In some embodiments, the circulation chamber outlet valve 107 is used to control the liquid path from the circulation chamber 102 to the liquid storage tank 105. The liquid storage tank inlet pump 108 is used to provide power for transporting the activated plasma liquid from the circulation chamber 102 to the liquid storage tank 105. When liquid needs to be transported from the circulation chamber 102 to the liquid storage tank 105, the control system can control the opening of the circulation chamber outlet valve 107 and the liquid storage tank inlet pump 108 to achieve the delivery of the circulated and activated plasma liquid to the liquid storage tank 105. In some embodiments, the circulation chamber outlet valve 107 may include an electric valve, and there are no particular limitations on the specific type of electric valve. Furthermore, there are no particular limitations on the type of the liquid storage tank inlet pump 108.

[0131] like Figure 1 and Figure 2As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a circulation chamber liquid inlet valve 109 , which is disposed on an injection pipeline connected to the injection inlet 1021 of the circulation chamber 102 and is in communication with the control system 121 .

[0132] In some embodiments, the circulation chamber inlet valve 109 is used to control the flow of an external liquid source (e.g., tap water, purified water, mineral water, saline, domestic sewage, milk, beverages, etc.) into the circulation chamber 102 of the plasma liquid activation system 100. When the circulation chamber 102 needs to be fed with liquid, the control system 121 controls the circulation chamber inlet valve 109 to open. When the flow of liquid into the circulation chamber 102 needs to be stopped, the control system 121 controls the circulation chamber inlet valve 109 to close. For example, in response to the circulation chamber low liquid level sensor 1042 detecting that the liquid level of the circulation chamber 102 is below the circulation chamber low threshold, the control system 121 controls the circulation chamber inlet valve 109 to open, allowing liquid to flow into the circulation chamber 102 to restart the circulation activation process. In response to the circulation chamber high liquid level sensor 1041 detecting that the liquid level of the circulation chamber 102 is above the circulation chamber high threshold, the control system 121 controls the circulation chamber inlet valve 109 to close, stopping the flow of liquid into the circulation chamber 102.

[0133] In some embodiments, the circulation chamber inlet valve 109 may include a solenoid valve or any other suitable type of electric valve.

[0134] like Figure 1 and Figure 2 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a water quality sensor 111 , which is disposed on an injection pipeline connected to the injection inlet 1021 of the circulation chamber 102 and is in communication with the control system 121 .

[0135] In some embodiments, the water quality sensor 111 is used to monitor the water quality of the external liquid source. The water quality sensor 111 may include, but is not limited to, a conductivity meter, a thermometer, and a pH meter.

[0136] In some embodiments of the present disclosure, the control system 121 can be used to control the closure of the circulation chamber inlet valve 109 based on the water quality of the circulation chamber sensed by the water quality sensor 111. For example, when the water quality sensed by the water quality sensor 111 is lower than a preset value, the circulation chamber inlet valve 109 can be controlled to close.

[0137] like Figure 1 and Figure 2 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a filter 110 , which is disposed in an injection pipeline connected to the injection inlet 1021 of the circulation chamber 102 , for example, between the circulation chamber inlet valve 109 and the water quality sensor 111 .

[0138] In some embodiments, the filter 110 may include various suitable filters, such as a coarse filter, which can be used to improve water quality, such as filtering out sediment, particulate matter, hair, etc. from an external liquid source to prevent such substances from entering the plasma liquid activation system 100 and damaging the pumps or pipelines within the system.

[0139] like Figure 1 and Figure 2 As shown, in some embodiments, the circulation chamber liquid inlet valve 109, the filter 110 and the water quality sensor 111 are arranged in sequence on the liquid injection pipeline connected to the liquid injection inlet 1021 of the circulation chamber 102, and the external liquid source enters the circulation chamber 102 after passing through the circulation chamber liquid inlet valve 109, the filter 110 and the water quality sensor 111 in sequence.

[0140] like Figure 1 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a liquid tank outlet pump 112, a pressure sensor 113, and a liquid tank outlet valve 114, which are disposed on a liquid outlet pipeline connected to the liquid storage outlet 1052 of the liquid storage tank 105. The liquid tank outlet pump 112 and the pressure sensor 113 are communicatively connected to a control system 121. The liquid tank outlet valve 114 may also be optionally communicatively connected to the control system 121.

[0141] In some embodiments of the present disclosure, the control system 121 is in communication with the liquid tank outlet pump 112 and the pressure sensor 113. The pressure sensor 113 is used to sense the outlet pressure of the liquid at the liquid storage outlet 1052 of the liquid storage tank 105. The control system 121 is used to control the opening and closing of the liquid tank outlet pump 112 based on the pressure sensed by the pressure sensor 113, thereby achieving automatic start and stop of the liquid tank outlet pump 112. For example, when the pressure sensor 113 senses that the outlet pressure of the liquid at the liquid storage outlet 1052 of the liquid storage tank 105 decreases or falls below a certain threshold, the control system 121 sends an instruction to control the liquid tank outlet pump 112 to turn on. When the pressure of the liquid at the liquid storage outlet 1052 of the liquid storage tank 105 increases or rises above a certain threshold, the control system 121 sends an instruction to turn off the liquid pump.

[0142] In some embodiments, there are no particular limitations on the type of liquid tank outlet pump 112. Liquid tank outlet valve 114 is used to control the opening and closing of the liquid outlet pipeline of plasma liquid activation system 100. Liquid tank outlet valve 114 can be an automatic valve to communicate with control system 121. Alternatively, liquid tank outlet valve 114 can be a manual valve (e.g., a manual ball valve), depending on the actual application scenario.

[0143] like Figure 1As shown, in some embodiments of the present disclosure, the plasma liquid generator 101 may include a generating chamber 1011, a first electrode 1012, and a second electrode 1013. The generating chamber 1011 may include an activation zone 10112 and an impact structure 10111. The impact structure 10111 is used to form a liquid shock wave and / or cavitation effect in the activation zone 10112. For example, water with a certain kinetic energy passes through the impact structure 10111, which can form a shock wave in the activation zone 10112. The first electrode 1012 is coupled to the generating chamber 1011. The second electrode 1013 is coupled to the generating chamber 1011, and is used to work together with the first electrode 1012 to generate an electric field in the activation zone 10112. As shown in FIG. Figure 1 and Figure 3 As shown, in some embodiments of the present disclosure, the plasma liquid generator 101 may include a plasma activation power supply 1014. The plasma activation power supply 1014 is connected to the first electrode 1012 and the second electrode 1013, and is in communication with the control system 121 for generating an electric field and adjusting the frequency of the electric field.

[0144] In some embodiments, the control system 121 can control the plasma activation power supply 1014 to turn on based on the liquid level of the circulation chamber 102 detected by the circulation chamber high liquid level sensor 1041 being higher than the circulation chamber high threshold, so as to start the circulation activation treatment of the liquid in the circulation chamber 102, and can control the plasma activation power supply 1014 to turn off based on the predetermined time of the control system 121 (for example, the plasma activation power supply 1014 is turned on for 1-5 minutes) or the predetermined number of cycles (for example, after the circulation pump 103 pumps a predetermined multiple of the volume of the liquid in the circulation chamber 102).

[0145] In some embodiments of the present disclosure, the frequency of the electric field resonates with the frequency of the liquid shock wave to efficiently activate the liquid.

[0146] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments of the present disclosure, the plasma liquid generator 101 may include an electrode compensation device (e.g., electrode compensation device 1015). The electrode compensation device 1015 may include a first drive device and / or a second drive device (not shown in the figure), and at least one sensor (e.g., sensor 10151). The first drive device is used to drive the first electrode 1012 to move to perform electrode compensation for the first electrode 1012. The second drive device is used to drive the second electrode 1013 to move to perform electrode compensation for the second electrode 1013. At least one sensor (e.g., sensor 10151) is coupled to the generator chamber 1011 to sense signals from the first electrode 1012 and / or the second electrode 1013.

[0147] like Figure 1 As shown, in some embodiments, the control system 121 is connected to the electrode compensation device (e.g., the electrode compensation device 1015) and is used to control the first driving device of the electrode compensation device to drive the first electrode 1012 to compensate the first electrode 1012, and / or control the second driving device of the electrode compensation device to drive the second electrode 1013 to compensate the second electrode 1013 based on the signals of the first electrode 1012 and the second electrode 1013 sensed by at least one sensor (e.g., sensor 10151).

[0148] In some embodiments, the sensor 10151 may include a photosensor disposed on the generator chamber 1011, capable of detecting the light intensity in the activation area 10112 and providing feedback to the control system 121. The control system 121 compares the light intensity with a set threshold. In response to the light intensity being lower than the set threshold, the control system 121 controls the first motor to drive the first electrode 1012 to move, for example, to advance the first set length.

[0149] In some embodiments, the driving device may include a motor (not shown in the figure). The motor can be used to drive the first electrode 1012 to move (eg, feed) to perform electrode compensation.

[0150] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the plasma liquid activation system 100 may only include an electrode compensation device 1015 for electrode compensation of the first electrode 1012. The second electrode 1013 is the outlet electrode. The electrode rod is thicker and has less wear and tear. It can generally be used for a long time, for example, more than a year, and can be directly replaced after reaching its service life. The first electrode 1012 at the water inlet wears more quickly. Therefore, in some embodiments, the electrode compensation device 1015 may be installed only at the first electrode 1012 at the water inlet. By driving the first electrode 1012 to move, the first electrode 1012 can maintain its original plasma water production efficiency even when it is continuously worn, thereby extending the service life of the equipment. The provision of the second electrode 1013 simplifies the structure of the plasma liquid generator and reduces production costs without affecting the plasma water production efficiency.

[0151] like Figure 1 As shown, in some embodiments of the present disclosure, the plasma liquid generator 101 may further include a housing 1016 and a buffer layer (not shown). The buffer layer is disposed between the inner wall of the housing 1016 and the generating chamber 1011 to wrap and fix the generating chamber 1011.

[0152] In some embodiments, the buffer layer can be a potting glue poured into the shell 1016, for example, any one or more of epoxy resin potting glue, polyurethane potting glue, silicone potting glue, and polyacrylate potting glue. The material used for the buffer layer has the advantages of high dielectric properties, anti-surface leakage, and arc resistance, which can effectively improve electrical safety. In the present disclosure, part of the structure of the generating chamber 1011, the first electrode 1012, and the second electrode 1013 is wrapped and fixed in the shell 1016 by the buffer layer. The buffer layer has high structural strength and hardness, and is chemically stable, acid-resistant, alkali-resistant, and corrosion-resistant. It can resist damage from the impact of water bodies, is fixed and shock-absorbing, and is waterproof and moisture-proof, thereby extending the service life of the equipment. In addition, the potting and fixing method enables the plasma liquid generator to be modular, easy to replace, and applicable to more application scenarios.

[0153] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments of the present disclosure, the plasma liquid generator 101 may further include a plug 1017. One end of the plug 1017 is connected to the plasma activation power supply 1014, and the other end is connected to the first electrode 1012 or the second electrode 1013.

[0154] In some embodiments of the present disclosure, the power of the plasma activation power supply 1014 is input to the second electrode 1013 of the plasma liquid generator 101 through the plug 1017. The plug 1017 is designed to facilitate plugging and unplugging, thereby achieving a modular design of the plasma liquid generator 101. The plug 1017 is separated from the plasma activation power supply 1014, allowing for separate assembly or maintenance, making it more convenient to use.

[0155] In some embodiments, the control system 121 may be an electronic and electrical control system for the entire plasma liquid activation system 100, and may be a single-chip microcomputer control system, a PLC control system, or other chip control system. The control system 121 may include chips, auxiliary circuit PCB boards, relays, and other auxiliary control components. All sensor signals of the plasma liquid activation system 100 (circulation chamber high liquid level sensor 1041, circulation chamber low liquid level sensor 1042, liquid storage tank high liquid level sensor 1061, liquid storage tank low liquid level sensor 1062, liquid storage tank middle liquid level sensor, water quality sensor 111, pressure sensor 113 and photosensor, etc.) can be connected to the control system 121. All electric pumps (including circulation pump 103, liquid storage tank inlet pump 108, liquid storage tank outlet pump 112), electric valves (including circulation chamber outlet valve 107, liquid storage tank outlet valve 114), plasma activation power supply 1014, electrode compensation device 1015, etc. can be communicated with the control system 121 and controlled by the control system 121 to achieve full automation of the plasma liquid activation system.

[0156] Figure 5 FIG. 1 shows an external view of a plasma liquid activation system 100 according to some embodiments of the present disclosure.

[0157] like Figure 5 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a housing 115 for accommodating a plasma liquid generator (e.g., Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The plasma liquid generator 101 shown in FIG. Figure 1 、 Figure 2 Circulation chamber 102 shown in FIG.

[0158] In some embodiments, housing 115 serves as a structural component of the plasma liquid activation system 100 and also provides a certain degree of structural support. In some embodiments, housing 115 may be made of sheet metal to shield the high-frequency signals emitted by the plasma activation power supply 1014 of the plasma liquid activation system 100, thereby protecting other devices from electromagnetic interference.

[0159] like Figure 4 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a cooling fan 116. The cooling fan 116 is disposed in the housing 115 and is used to dissipate heat from the plasma liquid generator 101.

[0160] like Figure 5 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include an operating indicator light 117. The operating indicator light 117 is disposed on the housing 115 and connected to the control system 121 to indicate different operating states of the plasma liquid activation system 100.

[0161] like Figure 5 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a power inlet 118. The power inlet 118 is disposed on the housing 115 and provides power to the plasma liquid activation system 100. In some embodiments, the power inlet 118 may be connected to an AC 220V mains power supply.

[0162] like Figure 5 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a liquid inlet 119. The liquid inlet 119 is provided on the housing 115 and communicates with the liquid injection inlet 1021 of the circulation chamber 102 (e.g., Figure 1 、 Figure 2 The liquid injection inlet 1021 of the circulation chamber 102 is shown in FIG.

[0163] In some embodiments, the external liquid source of the plasma liquid activation system 100 enters through the liquid inlet 119. The liquid inlet 119 may include a quick-connect interface, such as a 2-way quick-connect interface or a 3-way quick-connect interface commonly used on the market.

[0164] like Figure 1 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a liquid outlet 120. The liquid outlet 120 is provided on the housing 115 and communicates with the liquid storage outlet 1052 of the liquid storage tank 105 (e.g., Figure 1 1052 of the liquid storage tank 105 shown in FIG.

[0165] In some embodiments, the activated plasma liquid can be output from the liquid outlet 120. The liquid outlet 120 can include a quick-connect connector.

[0166] Figure 1 The plasma liquid generator 101 shown is only an exemplary structure, and other suitable plasma liquid generators may also be used. For example, Figure 6 Schematic diagrams of the structure of a plasma liquid generator 101a according to other embodiments of the present disclosure are shown.

[0167] like Figure 6 As shown, in some other embodiments of the present disclosure, the impact structure 10111a includes a rotating drum 101111 disposed in the activation area 10112a of the generating chamber 1011a. The rotating drum 101111 includes a plurality of through holes 101112 disposed on the side wall. Figure 6 As shown, the impact structure 10111a further includes a rotating shaft 101113, which is fixedly connected to the rotating drum 101111 to drive the rotating drum 101111 to rotate within the generating chamber 1011a, thereby generating shock waves in the liquid passing through the through hole 101112 of the rotating drum 101111. The plasma liquid generator 101a may further include a driving device (not shown), such as a motor, for driving the rotating shaft 101113 to rotate.

[0168] like Figure 6 As shown, the impact structure 10111a may further include a housing chamber 101114 for accommodating the drum 101111, and the generating chamber 1011a may further include an upstream chamber 10113 located upstream of the housing chamber 101114 and communicating with the housing chamber 101114, and a downstream chamber 10114 located downstream of the housing chamber 101114 and communicating with the housing chamber 101114. Figure 6 As shown, the cross-sectional dimensions of the upstream cavity 10113 and the downstream cavity 10114 are smaller than the cross-sectional dimensions of the accommodating cavity 101114 .

[0169] like Figure 1The circulating pump 103 shown can be used with Figure 6 The generating chamber 1011a shown is connected, and the liquid enters the accommodating chamber 101114 through the upstream chamber 10113 under the pressure of the circulating pump 103, and generates a liquid shock wave under the action of the high-speed rotating drum 101113.

[0170] like Figure 6 As shown, the plasma liquid generator 101a may further include a first electrode 1012a and a second electrode 1013a. The first electrode 1012a is disposed upstream or downstream of the impact structure 10111a, and the second electrode 1013a is disposed downstream of the impact structure 10111a. Figure 6 As shown, the first electrode 1012a is disposed at the upstream end of the upstream cavity 10113 (e.g., Figure 6 The second electrode 1013a is disposed at the downstream end of the downstream chamber 10114 (eg, as shown in FIG. Figure 6 right end as shown).

[0171] like Figure 6 As shown, in some embodiments of the present disclosure, the first electrode 1012a can be set in the upstream space of the generating chamber 1011a, upstream of the impact structure 10111a, and the second electrode 1013a can be set in the downstream space of the generating chamber 1011a, downstream of the impact structure 10111a.

[0172] In some embodiments of the present disclosure, the first electrode 1012 may be disposed on the outer sidewall of the generating chamber 1011, and the second electrode 1013 may also be disposed on the outer sidewall of the generating chamber 1011, and may be spaced apart from the first electrode. The first electrode 1012 may be located upstream of the impact structure 10111, and the second electrode 1013 may be located downstream of the impact structure 10111. Alternatively, both the first electrode 1012 and the second electrode 1013 may be located downstream of the impact structure 10111 and within the activation zone 10112.

[0173] In some embodiments of the present disclosure, Figure 6As shown, the plasma liquid generator 101a may further include a plasma activation power supply 1014a, which is connected to the first electrode 1012a and the second electrode 1013a and can be used to generate an electric field. In some embodiments of the present disclosure, the plasma activation power supply 1014a can also adjust the frequency of the electric field.
