Description

Technical Field

[0001] The invention relates to the technical field of agricultural product preservation, and in particular to a backpack plasma activated water generating device. Background Art

[0002] During the storage and transportation of fruits and vegetables, extending their shelf life is an important task. This is not only related to maintaining the freshness and nutritional quality of fruits and vegetables, but also crucial to reducing losses, reducing costs and improving economic benefits. Among them, sterilization and disinfection are particularly important during the storage and transportation of fruits and vegetables. However, traditional liquid disinfectants are easy to solidify and remain, which may cause damage to the organic molecular structure of food. Therefore, how to sterilize and disinfect fruits and vegetables more effectively without destroying the ingredients of fruits and vegetables is an urgent problem to be solved during the storage and transportation of fruits and vegetables.

[0003] Recent studies have found that water treated with plasma activation has a highly effective sterilization and disinfection effect. Plasma-activated water directly acts on bacteria and viruses and can have a similar sterilization and disinfection effect as disinfectants. However, the current plasma-activated water equipment on the market has poor flexibility and portability and cannot adapt to complex transportation and storage environments. In response to this, the present invention proposes a backpack plasma-activated water generator. Summary of the invention

[0009] Preferably, the plasma activated water generated in the plasma activated water generator assembly flows through the water pipe, successively passes through the third three-way joint, the fifth solenoid valve and the second water inlet arranged on the water pipe, and flows back to the large water tank; At the same time, the plasma activated water generated in the plasma activated water generator assembly flows through the water pipe, successively through the third three-way joint, the sixth solenoid valve and the water inlet of the small water tank, and flows into the small water tank; Through this design, the concentration of plasma-activated water in the large water tank can be continuously increased until the set value is reached, or a portion of low-concentration plasma-activated water can be preferentially prepared and stored in a small water tank.

[0026] A controller 5 is provided above the small water tank 2, and the controller 5 contains a high-voltage power supply 501 and a battery. The high-voltage power supply 501 is electrically connected to the plasma activated water generator assembly 9, and the battery supplies power to the entire device; The controller 5 is electrically connected to the first ion concentration detection sensor 1201 , the second ion concentration detection sensor 1202 , the first ultrasonic radar level meter 23 , the second ultrasonic radar level meter 24 and the display module 4 and communicates with the devices; The first ion concentration detection sensor 1201 and the second ion concentration detection sensor 1202 collect the concentration data of the plasma-activated water in the small water tank 2 and the large water tank 1 in real time and send it to the controller 5; the first ultrasonic radar level meter 23 and the second ultrasonic radar level meter 24 collect the water level data of the small water tank 2 and the large water tank 1 in real time and send it to the controller 5; the controller 5 can control the display module 4 to display the concentration data and water level data of the plasma-activated water in the large water tank 1 and the small water tank 2 in real time.

[0027] The large water tank 1, the small water tank 2 and the plasma activated water generator assembly 9 are connected to each other through a water pipe 16, and the water pipe 16 is provided with a first solenoid valve 301, a second solenoid valve 302, a third solenoid valve 303, a fourth solenoid valve 304, a fifth solenoid valve 305, a sixth solenoid valve 306, an eighth solenoid valve 308, a ninth solenoid valve 309, a first water pump 601, a second water pump 602, a first three-way joint 701, a second three-way joint 702, a third three-way joint 703, and a fourth three-way joint 704; the first three-way joint 701 is provided with a spray head 8 in the connection direction of the plasma activated water generator assembly 9; one end of the water pipe 16 is connected to the outside of the box body 13 and is connected to the spray gun 10.

[0028] The controller 5 is electrically connected to the first solenoid valve 301, the second solenoid valve 302, the third solenoid valve 303, the fourth solenoid valve 304, the fifth solenoid valve 305, the sixth solenoid valve 306, the seventh solenoid valve 307, the eighth solenoid valve 308, the ninth solenoid valve 309, the tenth solenoid valve 310, the first water pump 601, the second water pump 602 and the plasma-activated water generator assembly 9 and controls the switching of the devices. Example 2

[0029] See also Figure 1On the basis of the above-mentioned embodiment, in the backpack plasma activated water generating device, the water in the large water tank 1 flows through the large water tank outlet 17, the first solenoid valve 301, the second three-way joint 702, the first water pump 601, the first three-way joint 701 and the third solenoid valve 303 arranged on the water pipe 16 to the spray head 8. After passing through the spray head 8, the water becomes water mist and reaches the plasma activated water generator assembly 9. The plasma activated water generator assembly 9 generates plasma activated water through the high voltage provided by the high-voltage power supply 501. After passing through the spray head, the water becomes water mist, which is more conducive to contact with the plasma activated water generator assembly so as to more effectively generate plasma activated water.

[0030] Further, in this embodiment, the plasma activated water generated in the plasma activated water generator assembly 9 flows through the water pipe 16, successively through the third three-way joint 703, the fifth solenoid valve 305 and the second water inlet 18 provided on the water pipe 16, and flows back to the large water tank 1; At the same time, the plasma activated water generated in the plasma activated water generator assembly 9 flows through the water pipe 16, successively through the third three-way connector 703, the sixth solenoid valve 306 and the small water tank water inlet 20 arranged on the water pipe 16, and flows to the small water tank 2; Through this design, the concentration of plasma activated water in the large water tank 1 can be continuously increased until the set value is reached, or a portion of low-concentration plasma activated water can be preferentially prepared and stored in the small water tank.

[0031] Further, in the present embodiment, the low-concentration plasma-activated water in the small water tank 2 flows through the water pipe 16, successively through the first water outlet 19, the second solenoid valve 302, the second three-way joint 702, the first water pump 601, the first three-way joint 701, the third solenoid valve 303 and the spray head 8 to reach the plasma-activated water generator assembly 9; The low-concentration plasma-activated water in the water pipe 16 flows through the plasma-activated water generator assembly 9 to increase its concentration, and then flows through the water pipe 16, successively through the third three-way connector 703, the sixth solenoid valve 306 and the small water tank water inlet 20 provided on the water pipe 16, and flows back to the small water tank 2; Through this design, the concentration of plasma activated water in small water tank 2 can be continuously increased until it reaches the set value.

[0032] Furthermore, in the present embodiment, after the concentration of the plasma-activated water in the large water tank 1 reaches a set value through the second ion concentration detection sensor 1202, the plasma-activated water flows through the large water tank outlet 17, the first solenoid valve 301, the second three-way joint 702, the first water pump 601, the first three-way joint 701, the fourth solenoid valve 304, the eighth solenoid valve 308 and the fourth three-way joint 704 arranged on the water pipe 16 to the spray gun 10, and then the plasma-activated water is sprayed out through the spray gun 10.

[0033] After the concentration of the plasma activated water in the small water tank 2 reaches the set value through the first ion concentration detection sensor 1201, it flows through the water pipe 16, successively through the second water outlet 21 of the small water tank arranged on the water pipe 16, the second water pump 602, the ninth solenoid valve 309 and the fourth three-way connector 704 to the spray gun 10, and then the plasma activated water is sprayed out through the spray gun 10.

[0034] Specifically, when in use, when the user needs plasma activated water, the water inlet cover 14 needs to be opened to inject water into the large water tank 1 through the first water inlet 22 of the large water tank. The second ultrasonic radar level gauge 24 sends the water level information of the large water tank 1 to the controller 5. After the controller 5 detects the change in the water level of the large water tank 1, the first solenoid valve 301, the third solenoid valve 303, the sixth solenoid valve 306, the seventh solenoid valve 307, the tenth solenoid valve 310 and the first water pump 601 are opened. The water in the large water tank 1 is pressurized by the first water pump 601 and transported to the spray head 8 through the water pipe 16. After passing through the spray head 8, the water becomes water mist and reaches the plasma activated water generator assembly 9 and reacts with the plasma generated by the plasma activated water generator assembly 9 to become low-concentration plasma activated water. After the low-concentration plasma activated water is generated, it continues to be transported to the small water tank 2 through the water pipe 16. This operation is continued and the water level of the small water tank 2 is continuously detected through the first ultrasonic radar level gauge 23. When the water level of the small water tank 2 reaches the threshold, the controller 5 closes the first solenoid valve 301 and opens the second solenoid valve 302. The other solenoid valves and the water pump remain in the same state. The first water pump 601 pressurizes and extracts low-concentration plasma-activated water from the small water tank 2. The low-concentration plasma-activated water is atomized through the spray head 8 and then enters the plasma-activated water generator assembly 9 to react with the plasma again to increase the concentration of the plasma-activated water and then returns to the small water tank 2. This operation is circulated and the concentration of the plasma-activated water in the small water tank 2 is continuously detected through the first ion concentration detection sensor 1201. When the concentration of the plasma activated water in the small water tank 2 reaches the threshold, the controller 5 prompts the user through the display module 4 that the preparation of the plasma activated water in the small water tank 2 is completed and opens the ninth solenoid valve 309 and the second water pump 602. The second water pump 602 pressurizes the activated water in the small water tank 2 so that it can be transported to the atomizing gun 10 through the water pipe 16, so that the user can use the atomizing gun 10 to spray the activated water from the small water tank 2; When the controller 5 opens the ninth solenoid valve 309 and the second water pump 602, the first solenoid valve 301 and the fifth solenoid valve 305 are opened, and the second solenoid valve 302 and the sixth solenoid valve 306 are closed. The other solenoid valves and water pumps remain unchanged. The water in the large water tank 1 is pressurized by the first water pump 601 and transported to the spray head 8 through the water pipe 16. After passing through the spray head 8, the water becomes water mist and reaches the plasma activated water generator component 9 and reacts with the plasma generated by the plasma activated water generator component 9 to become low-concentration plasma activated water. After the low-concentration plasma activated water is generated, it continues to be transported to the large water tank 1 through the water pipe 16. This operation is repeated and continuously detected by the second ion concentration detection sensor 1202. The concentration of plasma activated water in the large water tank 1 is adjusted; when the concentration of plasma activated water in the large water tank 1 reaches a threshold value, the controller 5 prompts the user through the display module 4 that the preparation of plasma activated water in the large water tank 1 is completed, and opens the fourth solenoid valve 304 and the eighth solenoid valve 308 while closing the third solenoid valve 303, the fifth solenoid valve 305, the ninth solenoid valve 309, the second water pump 602 and the plasma activated water generator assembly 9, and the states of the other solenoid valves and water pumps remain unchanged, so that the device no longer generates plasma, and the plasma activated water in the large water tank 1 is pressurized by the first water pump 601 and preferentially transported to the atomizer gun 10 through the water pipe 16, so that the user can use the atomizer gun 10 to spray the activated water from the large water tank 1.

[0035] While the user is using the activated water in the large water tank 1, the controller 5 continuously detects the water level of the large water tank 1 through the second ultrasonic radar level gauge 24. When the water level of the large water tank 1 is lower than a certain water shortage threshold, the controller 5 alerts the user of the water shortage through the control display module 4. At the same time, the controller 5 opens the third solenoid valve 303 and the sixth solenoid valve 306 to ensure that the atomizer gun 10 supplies plasma activated water while replenishing plasma activated water to the small water tank 2. When the water level of the small water tank 2 reaches the threshold, the third solenoid valve 303 and the sixth solenoid valve 306 are closed. When the water level of the large water tank 1 is lower than the minimum water level threshold, the controller 5 alerts the user of the water shortage through the control display module 4. At the same time, the ninth solenoid valve 309 and the second water pump 602 are opened to keep the seventh solenoid valve 307 open, and the remaining solenoid valves and water pumps are closed to allow the user to use the atomizer gun 10 to spray the activated water from the small water tank 2 until the activated water in the small water tank 2 is lower than the minimum water level threshold.

[0036] Through the design of the large and small water tanks and the above-mentioned control method, the liquid in the small water tank 2 can be pre-treated, and then the liquid in the large water tank 1 can be treated, which can greatly shorten the activation time and allow users to use the plasma activated water produced by this equipment as quickly as possible when plasma activated water is needed. In addition, the plasma activated water in the small water tank 2 can also be used when the water supply is urgent, which can ensure the longest application of plasma activated water.

[0037] The solution in this embodiment can be selectively combined with the solutions in other embodiments for use. Example 3

The anode plate 902 and the cathode plate 906 are wrapped by carbon fiber 903 and a glass tube 905, and insulating sealing rings 901 are installed on the upper and lower sides.

[0039] The anode plate 902 and the cathode plate 906 do not generate any secondary pollutants such as ozone during the preparation of plasma activated water.
