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, the plasma and the solution in the liquid will produce a series of complex reactions, including the generation of hydroxyl radicals (OH·), singlet oxygen ( 1 O 2 ), superoxide anion (O 2 ·- ), hydronium ion (H 3 O + ), nanoparticles and other active substances, which can kill microorganisms such as bacteria and viruses.

[0003] Through the resonance of electromagnetic field and mechanical wave energy, or through electric field and hydrodynamic cavitation effect, sustainable plasma excitation can be achieved with a lower voltage to obtain 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 requirements for sterilization and disinfection, especially the sterilization and disinfection requirements in medical and other fields. Summary of the invention

[0004] The present disclosure provides a plasma liquid activation system, comprising:

[0005] a plasma liquid generator for activating the liquid; and

[0006] The circulation chamber is communicated with the plasma liquid generator and is used for conveying the liquid to be activated to the plasma liquid generator and receiving the activated liquid from the plasma liquid generator so as to perform circulation activation treatment on the liquid.

[0034] Figure 1 A schematic structural diagram of a plasma liquid activation system 100 according to some embodiments of the present disclosure is shown. Figure 2 A schematic diagram showing 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 showing the internal back structure of a plasma liquid activation system 100 according to some embodiments of the present disclosure is shown.

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the present disclosure, the 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 the liquid. The circulation chamber 102 is in communication with the plasma liquid generator 101, and is used to transport the liquid to be activated to the plasma liquid generator 101, and receive the activated liquid from the plasma liquid generator 101, so as to perform a circulation activation treatment on the liquid.

[0036] In the plasma liquid activation system 100 of the present disclosure, the activated liquid passes through the plasma liquid generator 101, and the concentration of active substances can be further improved. The plasma liquid activation system 100 of some embodiments of the present disclosure, by providing a circulation chamber 102, allows the activated liquid to circulate multiple times to increase the content of active substances, thereby improving the sterilization and disinfection performance of the plasma liquid.

[0037] In some embodiments, the liquid to be activated may include a 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 a 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.

[0038] 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.

[0039] like Figure 4As 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 run for a predetermined time or a predetermined number of cycles to perform a cyclic activation treatment on the liquid. It will be appreciated by those skilled in the art that the control system 121 may include a single controller or a plurality of 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 a control circuit, control software, and the like.

[0040] 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-input into the control system 121 to realize the automation of liquid activation and obtain the desired activated liquid.

[0041] 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 the circulation activation. The liquid storage tank 105 may include a liquid storage inlet 1051. The circulation chamber 102 may also 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, and is used to receive the plasma liquid after the circulation activation.

[0042] 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 .

[0043] 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 lower than a circulation chamber low threshold (eg, Figure 1 The control system 121 can also be used to respond to the liquid level of the circulation chamber 102 being higher than the circulation chamber high threshold value (for example, the high liquid level signal of the circulation chamber detected by the circulation chamber liquid level detection device 104), stop the liquid discharge of the circulation chamber 102 (for example, control the circulation chamber liquid outlet valve 107 to be closed), and start the liquid inlet of the circulation chamber 102 (for example, control the circulation chamber liquid inlet valve 109 to be opened). The control system 121 can also be used to respond to the liquid level of the circulation chamber 102 being higher than the circulation chamber high threshold value (for example, the circulation chamber high liquid level signal detected by the circulation chamber liquid level detection device 104), stop the liquid inlet (for example, control the circulation chamber liquid inlet valve 109 to be closed), and control the plasma liquid generator 101 to run for a predetermined time or a predetermined number of cycles to perform a circulation activation treatment on the liquid.

[0044] 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 .

[0045] 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 lower than a liquid tank low threshold (eg, Figure 1 The control system 121 can also be used to respond to the liquid level of the liquid tank 105 being higher than the high threshold value of the liquid tank (for example, the high liquid level signal of the liquid tank 105 detected by the liquid tank liquid level detection device 106), stop the liquid tank 105 from being filled with liquid (for example, the control system 121 controls the circulating chamber liquid outlet valve 107 and the liquid tank liquid inlet pump 108 to be closed).

[0046] In some embodiments of the present disclosure, the control system 121 may also be used to control the liquid inlet and outlet 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 .

[0047] In some embodiments of the present disclosure, the control system 121 may be configured to respond to the liquid level of the liquid tank 105 being below a liquid tank low threshold (eg, 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 value (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 into the circulating chamber 102 (for example, controlling the circulating chamber liquid inlet valve 109 to open).

[0048] 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 a middle threshold of the liquid storage tank (for example, a 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 a low threshold of the circulation chamber.

[0049] 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 lower than a liquid tank low threshold (eg, Figure 1In some embodiments, the control system 121 may also be used to respond to the liquid level of the liquid storage tank 105 being lower than the middle threshold of the liquid storage tank (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 not lower than the low threshold of the circulation chamber, start the liquid discharge of the circulation chamber 102 (for example, control the circulation chamber liquid discharge valve 107 and the liquid storage tank liquid inlet pump 108 to be turned on).

[0050] In some embodiments, when the liquid level of the liquid storage tank 105 is lower than a preset value, for example, lower than a lower threshold value of the liquid storage tank or lower than a middle threshold value of the liquid storage tank, the control system 121 will first determine whether there is any plasma liquid after circulation activation in the circulation chamber 102 (for example, determine whether the liquid level of the circulation chamber 102 is lower than the lower threshold value of the circulation chamber). If so (for example, determine whether the liquid level of the circulation chamber 102 is not lower than the lower threshold value of the circulation chamber), the liquid discharge of the circulation chamber 102 will be started first (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 lower threshold value of the circulation chamber, the control system 121 stops the liquid discharge of the circulation chamber 102 and starts the liquid intake of the circulation chamber 102 to prepare the plasma liquid after circulation activation again.

[0051] In some embodiments, the liquid level of the liquid storage tank 105 is lower than the 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 cyclic activated plasma liquid. When the liquid level of the liquid storage tank 105 is lower than the liquid storage tank low threshold, the control system 121 will first determine whether there is cyclic activated plasma liquid in the circulation chamber 102 (for example, it can be determined based on the circulation chamber liquid level detection device 104). If there is, the cyclic activated plasma liquid is first output (for example, delivered to the liquid storage tank 105 or discharged as waste liquid), and then the circulation chamber 102 is controlled to start liquid inlet to prepare the cyclic activated plasma liquid again.

[0052] In some embodiments of the present disclosure, the control system 121 can be used to start the liquid inflow 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, the activated liquid has been processed, and the activated liquid is obtained (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 liquid inflow 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).

[0053] In some embodiments of the present disclosure, the control system 121 may also be configured to respond to the mass of the liquid injected into the circulation chamber 102 being lower than a mass threshold (e.g., based on Figure 1 The water quality sensor 111 shown in the figure senses the water quality of the circulation chamber 102 ), and stops the liquid inlet into the circulation chamber 102 (for example, the control system 121 controls the circulation chamber liquid inlet valve 109 to be closed).

[0054] like Figure 1 and Figure 2 As 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 communicated with 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 communicated with the outlet of the plasma liquid generator 101, and is used to receive the activated liquid from the plasma liquid generator 101, so as to perform a circulation activation treatment on the liquid.

[0055] 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 communicated with the circulation outlet 1022 of the circulation chamber 102, and the liquid outlet is communicated with 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.

[0056] 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 run for a predetermined time or a predetermined number of cycles to perform a cyclic activation treatment on the liquid.

[0057] 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 is repeated 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.

[0058] 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.

[0059] In some embodiments, the circulation pump 103 is used to provide liquid circulation power to the plasma liquid activation system 100, especially to provide the required liquid pressure to the plasma liquid generator 101, so the maximum pressure of the circulation pump 103 generally needs to reach 1MPa or more. In some embodiments, the circulation pump 103 can include a diaphragm pump, a plunger pump, or other liquid pump that can provide a relatively high pressure.

[0060] 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 communicatively connected to the control system 121 and is used to detect the liquid level in the circulation chamber 102 .

[0061] 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.

[0062] In some embodiments, the control system 121 is used to control the circulation chamber 102 to enter liquid 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., the low liquid level signal of the circulation chamber 102 detected by the circulation chamber low liquid level sensor 1042), so as to restart the circulation activation treatment of the liquid. The control system 121 is used to control the circulation chamber to stop entering 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., the high liquid level signal of the circulation chamber 102 detected by the circulation chamber high liquid level sensor 1041).

[0063] 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 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.

[0064] In some embodiments, the circulation chamber 102 is used to accommodate the total amount of liquid to be activated in the circulation of the liquid, and is designed to be slender, narrow and high, which is conducive to improving the efficiency and circulation uniformity of the liquid to be activated. Through a simple structure, no other auxiliary equipment is required, and it can effectively prevent some liquids from being unable to be effectively circulated. In some embodiments, the ratio of the height to the width of the circulation chamber can be greater than 1, for example, the ratio of the height to the width can be any interval or any value of 1.1-2, 1.5-5, 2-20.

[0065] 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 communicatively connected to the control system 121 and is used to detect the liquid level in the liquid tank 105 .

[0066] like Figure 1 As shown, in some embodiments of the present disclosure, the liquid tank liquid 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.

[0067] In some embodiments, when the liquid storage tank 105 receives the plasma liquid after the circulation activation of the circulation chamber 102, the control system 121 responds 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 (for example, 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 responds 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 (for example, controlling the liquid storage tank 105 to stop taking in liquid. When the liquid in the liquid storage tank 105 is discharged (for example, when the user takes water), the liquid storage tank low level sensor 1062 detects the low liquid level signal of the liquid storage tank 105), and controls the liquid storage tank 105 to stop discharging liquid.

[0068] In some embodiments, the control system 121 can be used to start the liquid inflow of the circulation chamber 102 in response to the liquid level of the liquid tank 105 detected by the liquid tank low liquid level sensor 1062 being lower than the liquid tank low threshold and the liquid level of the circulation chamber 102 detected by the circulation chamber low liquid level detection device 1042 being lower than the circulation chamber low threshold. The control system 121 can also be used to start the liquid outflow of the circulation chamber 102 in response to the liquid level of the liquid tank 105 detected by the liquid tank low liquid level sensor 1062 being lower than the liquid tank low threshold and the liquid level of the circulation chamber 102 not being lower than the circulation chamber low threshold.

[0069] In other embodiments of the present disclosure, the liquid level detection device 106 of the liquid storage tank may further include a liquid level sensor in the liquid storage tank (not shown in the figure), which is arranged in the liquid storage tank 105 and located between the high liquid level sensor 1061 and the low liquid level sensor 1062 of the liquid storage tank. The liquid level sensor in the liquid storage tank may be arranged at any position between the high liquid level sensor 1061 and the low liquid level sensor 1062 of the liquid storage tank, for example, in the middle of the high liquid level sensor 1061 and the low liquid level sensor 1062 of the liquid storage tank, or closer to the high liquid level sensor 1061 of the liquid storage tank, or closer to the low liquid level sensor 1062 of the liquid storage tank. The liquid level sensor in the liquid storage tank is used to monitor the liquid level of the liquid storage tank 105 between the high liquid level and the low liquid level.

[0070] In some embodiments, the control system 121 can be used to start the liquid inflow of 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 the liquid tank medium threshold (for example, the 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 the circulation chamber low threshold. Starting the liquid inflow of the circulation chamber 102 based on the liquid level of the liquid tank 105 being lower than the liquid tank medium threshold can ensure that the user will not be short of water when taking water from the liquid tank 105 or reduce the waiting time of the user.

[0071] In some embodiments, the control system 121 can also be used to start the liquid discharge of 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 and the liquid level of the circulation chamber 102 being not lower than the circulation chamber low threshold. In this way, when there is still liquid in the liquid storage tank 105, the liquid that has been circulated and activated can be added to the liquid storage tank 105 from the circulation chamber 102 in advance to avoid running out of liquid in the liquid storage tank 105.

[0072] In some embodiments, after the liquid storage tank 105 receives the plasma liquid after cyclic activation, the control system 121 can automatically start the liquid discharge action of the liquid storage tank 105 based on the signal that the liquid level of the liquid storage tank low liquid level sensor 1062 is not lower than the liquid storage tank low threshold, for example, when the liquid storage tank outlet valve 114 is open.

[0073] like Figure 1 and Figure 2 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may also 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.

[0074] In some embodiments, the circulation chamber outlet valve 107 is used to control the liquid circuit switch from the circulation chamber 102 to the liquid storage tank 105, and 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 it is necessary to infuse liquid 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 realize the delivery of the circulated activated plasma liquid to the liquid storage tank 105. In some embodiments, the circulation chamber outlet valve 107 can include an electric valve, and there is no particular limitation on the specific type of the electric valve. Moreover, there is no particular limitation on the type of the liquid storage tank inlet pump 108.

[0075] 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 inlet valve 109 , which is disposed on an injection pipeline connected to an injection inlet 1021 of the circulation chamber 102 and is in communication with the control system 121 .

[0076] In some embodiments, the circulation chamber inlet valve 109 is used to control the external liquid source (such as tap water, purified water, mineral water, physiological saline, domestic sewage, milk, beverage, etc.) to enter the circulation chamber 102 of the plasma liquid activation system 100. When the circulation chamber 102 needs to be filled with liquid, the control system 121 controls the circulation chamber inlet valve 109 to open. When it is necessary to stop the liquid from entering the circulation chamber 102, the control system 121 controls the circulation chamber inlet valve 109 to close. For example, 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, the control system 121 controls the circulation chamber inlet valve 109 to open, and the circulation chamber 102 is filled with liquid, so as to restart the circulation activation treatment of the 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, the control system 121 controls the circulation chamber inlet valve 109 to close, and the circulation chamber 102 stops filling with liquid.

[0077] In some embodiments, the circulation chamber inlet valve 109 may include a solenoid valve or any other suitable type of electric valve.

[0078] 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 an injection inlet 1021 of the circulation chamber 102 and is in communication with a control system 121 .

[0079] 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.

[0080] In some embodiments of the present disclosure, the control system 121 can be used to control the closing 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.

[0081] 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 disposed in an injection pipeline connected to the injection inlet 1021 of the circulation chamber 102 , for example, disposed between the circulation chamber inlet valve 109 and the water quality sensor 111 .

[0082] 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 mud, particulate matter, hair, etc. in an external liquid source to prevent such substances from entering the plasma liquid activation system 100 and damaging the pumps or pipelines in the system.

[0083] 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 sequentially arranged 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.

[0084] like Figure 1 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a liquid storage tank outlet pump 112, a pressure sensor 113, and a liquid storage tank outlet valve 114, which are arranged on a liquid outlet pipeline connected to the liquid storage outlet 1052 of the liquid storage tank 105, and the liquid storage tank outlet pump 112 and the pressure sensor 113 are communicatively connected to the control system 121. The liquid storage tank outlet valve 114 may also be optionally communicatively connected to the control system 121.

[0085] 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 storage outlet 1052 of the liquid storage tank 105. The control system 121 is used to control the opening and closing of the liquid storage tank outlet pump 112 based on the pressure sensed by the pressure sensor 113, so as to realize the automatic start and stop of the liquid storage tank outlet pump 112. For example, when the pressure sensor 113 senses that the outlet pressure of the liquid storage outlet 1052 of the liquid storage tank 105 becomes smaller or lower than a certain threshold, the control system 121 sends an instruction to control the opening of the liquid storage tank outlet pump 112. When it is sensed that the outlet pressure of the liquid storage outlet 1052 of the liquid storage tank 105 becomes larger or higher than a certain threshold, the control system 121 sends an instruction to close the outlet pump.

[0086] In some embodiments, there is no particular limitation on the type of the liquid tank outlet pump 112. The liquid tank outlet valve 114 is used to control the switch of the liquid outlet pipeline of the plasma liquid activation system 100. The liquid tank outlet valve 114 can be an automatic valve to communicate with the control system 121. The liquid tank outlet valve 114 can also be a manual valve (e.g., a manual ball valve), which is determined according to the actual application scenario.

[0087] like Figure 1 As 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 a 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. 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 to generate an electric field and adjust the frequency of the electric field.

[0088] 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).

[0089] 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.

[0090] 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 driving device and / or a second driving device (not shown in the figure), and at least one sensor (e.g., sensor 10151). The first driving device is used to drive the first electrode 1012 to move so as to perform electrode compensation of the first electrode 1012. The second driving device is used to drive the second electrode 1013 to move so as to perform electrode compensation of the second electrode 1013. At least one sensor (e.g., sensor 10151) is coupled to the generating chamber 1011 to sense signals of the first electrode 1012 and / or the second electrode 1013.

[0091] 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., the sensor 10151).

[0092] In some embodiments, the sensor 10151 may include a photosensitive sensor, which is disposed on the generating chamber 1011 and can be used to detect the light intensity of the activation area 10112 and feed back 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 feed a first set length.

[0093] 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.

[0094] 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 electrode at the water outlet, and the electrode rod is thicker and has less loss. It can usually be used for a long time, such as more than one year. After reaching the service life, it can be directly replaced. The first electrode 1012 located at the water inlet end wears faster, so in some embodiments, the electrode compensation device 1015 can be set only at the first electrode 1012 at the water inlet end. By driving the first electrode 1012 to move, the first electrode 1012 can still maintain the original plasma water production efficiency when it is continuously worn, and the service life of the equipment can be extended. The setting of the second electrode 1013 makes the plasma liquid generator simpler in structure and reduces production costs without affecting the plasma water production efficiency.

[0095] 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 in the figure). 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.

[0096] 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 in 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.

[0097] like Figure 1 , Figure 2 , Figure 3 and Figure 4As 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.

[0098] In some embodiments of the present disclosure, the electric energy of the plasma activation power supply 1014 is input to the second electrode 1013 of the plasma liquid generator 101 through the plug 1017. By designing the plug 1017, it is convenient to plug and unplug, so that the plasma liquid generator 101 can be modularly designed and separated from the plasma activation power supply 1014, so that it can be assembled or maintained separately, which is more convenient to use.

[0099] In some embodiments, the control system 121 may be an electronic and electrical control system in the entire plasma liquid activation system 100, and may be a single chip control system, a PLC control system, or other chip control systems. The control system 121 may include chips, auxiliary circuit PCB boards, relays, and other auxiliary control devices. Various 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 all be connected to the control system 121, and 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 connected to the control system 121 for communication and control by the control system 121 to realize full automation of the plasma liquid activation system.

[0100] Figure 5 FIG. 1 shows an external view of a plasma liquid activation system 100 according to some embodiments of the present disclosure.

[0101] 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 Figure 1 , Figure 2 Circulation chamber 102 shown in FIG.

[0102] In some embodiments, the housing 115 is an exterior structural component of the plasma liquid activation system 100 and can play a certain role in frame support. In some embodiments, the housing 115 can be made of sheet metal to shield the high-frequency signal emitted by the plasma activation power supply 1014 of the plasma liquid activation system 100, so that other devices are protected from electromagnetic interference.

[0103] like Figure 4 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a heat dissipation fan 116. The heat dissipation fan 116 is disposed in the housing 115 and is used to dissipate heat from the plasma liquid generator 101.

[0104] like Figure 5 As shown, in some embodiments of the present disclosure, the plasma liquid activation system 100 may further include a working indicator light 117. The working indicator light 117 is disposed on the housing 115 and connected to the control system 121 to indicate different working states of the plasma liquid activation system 100.

[0105] 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 power is provided to the plasma liquid activation system 100 through the power inlet 118. In some embodiments, the power inlet 118 may be connected to AC220V mains power.

[0106] 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 disposed on the housing 115 and communicates with the liquid injection inlet 1021 of the circulation chamber 102 (for example, Figure 1 , Figure 2 The liquid injection inlet 1021 of the circulation chamber 102 is shown in FIG.

[0107] In some embodiments, the external liquid source of the plasma liquid activation system 100 enters from the liquid inlet 119. The liquid inlet 119 may include a quick-plug interface, for example, a 2-point quick-plug interface or a 3-point quick-plug interface commonly used in the market.

[0108] 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 disposed on the housing 115 and communicates with the liquid storage outlet 1052 of the liquid storage tank 105 (for example, Figure 1 The liquid storage outlet 1052 of the liquid storage tank 105 is shown in FIG.

[0109] 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.

[0110] The plasma liquid activation system of some embodiments of the present disclosure is small in size, easy to operate, and can be used immediately, thus having a wide range of applications.

[0111] Figure 1 The plasma liquid generator 101 shown is only an exemplary structure, and other suitable structures of plasma liquid generators may also be used. For example, Figure 6 A schematic structural diagram of a plasma liquid generator 101a according to some other embodiments of the present disclosure is shown.

[0112] like Figure 6 As shown, in some other embodiments of the present disclosure, the impact structure 10111a includes a drum 101111 disposed in the activation zone 10112a of the generating chamber 1011a. The 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 in the generating chamber 1011a, so that the liquid passing through the through hole 101112 of the rotating drum 101111 forms a shock wave. The plasma liquid generator 101a may also include a driving device (not shown) for driving the rotating shaft 101113 to rotate, such as a motor.

[0113] like Figure 6 As shown, the impact structure 10111a may further include a housing chamber 101114 for housing 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 .

[0114] like Figure 1 The circulation pump 103 shown can be used with Figure 6 The generating chamber 1011a shown is connected, and the liquid enters the containing chamber 101114 through the upstream chamber 10113 under the pressure of the circulating pump 103, and a liquid shock wave is generated under the action of the high-speed rotating drum 101113.

[0115] like Figure 6As 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 the left end). Figure 6 right end as shown).

[0116] like Figure 6 As shown, in some embodiments of the present disclosure, the first electrode 1012a can be disposed in the upstream space of the generating chamber 1011a, upstream of the impact structure 10111a, and the second electrode 1013a can be disposed in the downstream space of the generating chamber 1011a, downstream of the impact structure 10111a.

[0117] In some embodiments of the present disclosure, the first electrode 1012 may be disposed on the outer side wall of the generating chamber 1011, and the second electrode 1013 may also be disposed on the outer side wall 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 in the activation zone 10112.

[0118] In some embodiments of the present disclosure, Figure 6 As shown, the plasma liquid generator 101a may also 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. Resonance can be achieved by adjusting the frequency of the electric field (for example, adjusting the frequency of the power supply) or adjusting the frequency of the liquid shock wave (for example, adjusting the pressure of the circulating pump 103). In some embodiments of the present disclosure, the frequency of the plasma activation power supply 1014a can be 2KHZ-200KHZ, and the pressure of the circulating pump 103 or the frequency of the plasma activation power supply 1014a can be used to make the frequency or frequency multiple of the liquid shock wave generated in the activation zone 10112a close to the frequency or frequency multiple of the electric field, thereby completing the preparation of the plasma liquid.

Among them, the right column is the sterilization test result of the plasma water obtained by cyclic treatment 7 times by the plasma liquid activation system 100. The left column is the sterilization test result of the activated water obtained by being treated once by the plasma liquid generator 101. A00 is the control group, which is the test result of directly dripping the bacterial liquid into ordinary tap water, taking an appropriate amount of the mixed liquid, and applying it to the culture dish. A0 is the test result of dripping the bacterial liquid into the activated water, taking a sample immediately after stirring, and applying it to the culture dish. A1 is the test result of dripping the bacterial liquid into the activated water, stirring, standing for 10 minutes, taking a sample, and applying it to the culture dish. A2 is the test result of dripping the bacterial liquid into the activated water, stirring, standing for 30 minutes, taking a sample, and applying it to the culture dish.

[0120] like Figure 7 As shown, the sterilization ability of the plasma liquid (e.g., plasma water) after cyclic activation obtained by the plasma liquid activation system 100 according to some embodiments of the present disclosure, especially the short-term rapid sterilization ability, is greatly improved, and the instantaneous sterilization ability can be almost 100% (see Figure 7 Right column A0).

[0121] By using the plasma liquid activation system 100 in some embodiments of the present disclosure, the content of active substances in the plasma-activated water can be increased through circulation, thereby improving the bactericidal and disinfecting performance of the plasma liquid after the cyclic activation, especially improving the short-time and rapid bactericidal and disinfecting performance of the plasma liquid after the cyclic activation, so that it can be applied to disease treatment, oral care, food preservation, fruit and vegetable washing, beauty, water purification and other fields with high requirements for bactericidal and disinfecting.

[0122] It should be pointed out that the above are only exemplary embodiments of the present disclosure and are not intended to limit the present disclosure.
