[0038] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] To improve the sterilization effect in low-temperature storage environments, this invention provides a sterilization device for low-temperature storage environments, which may include a first discharge device and a second discharge device. The first discharge device can generate plasma and / or ozone, and the second discharge device can generate ozone. The plasma generated by the device can charge and collect particles in the low-temperature storage environment, thereby avoiding particle contamination of the stored products. In addition, the ozone generated by the device can diffuse throughout the low-temperature storage environment, thereby eliminating microorganisms in the low-temperature storage environment and achieving a highly efficient sterilization effect in the low-temperature storage environment.

[0040] Reference Figure 1a The diagram shows a sterilization device for low-temperature storage environments according to an embodiment of the present invention. The device may include a first discharge device and a second discharge device.

[0041] The first discharge device includes two first plates arranged opposite each other, and a high-voltage electrode located between the two first plates; the two first plates are grounded, and the high-voltage electrode is connected to a first power supply; the high-voltage electrode is located at the first end of the two first plates.

[0042] The second discharge device is located between the two first plates of the first discharge device, and the second discharge device is located at the second end of the first discharge device; the second discharge device includes two opposing second plates and a plate-shaped discharge electrode located between the two second plates; the plate-shaped discharge electrode is connected to a second power source.

[0043] In practical applications, the first electrode and the high-voltage electrode in the first discharge device can form a stable electric field; thus, the high-voltage electrode can impart a charge to the particles in the low-temperature storage environment; the charged particles will be captured by the first electrode. The low-temperature storage environment can refer to a cold storage room, refrigerator, etc., and this embodiment of the invention does not limit this.

[0044] Specifically, the two first plates in the first discharge device can be arranged parallel to each other in a low-temperature storage environment; the two first plates can be grounded respectively; the high-voltage electrode in the first discharge device can be arranged between the two first plates, and the high-voltage electrode can be connected to a first power source; the first power source can supply power to the high-voltage electrode, thereby forming a stable electric field between the first plates and the high-voltage electrode.

[0045] After the high-voltage electrode is powered by the first power source, it can generate and release plasma in all directions. The released plasma can come into contact with particles in the low-temperature storage environment, thereby charging the particles. The charged particles will be affected by the electric field formed between the first electrode and the high-voltage electrode, and will move closer to the first electrode, thus being captured and collected by the first electrode. Thus, the first dust collection is completed.

[0046] In one embodiment of the present invention, the high-voltage electrode can be a tungsten wire or a tungsten rod, and the high-voltage electrode can have a small radius of curvature to facilitate plasma excitation.

[0047] The aforementioned device may also include a second discharge device, in which a stable electric field can be formed between the second electrode plate and the plate-shaped discharge electrode to capture particles a second time. Additionally, the second discharge device can convert oxygen in the air to generate ozone for sterilization and disinfection of the low-temperature storage environment.

[0048] In practical applications, the second discharge device can be set between the two first plates; specifically, the high voltage electrode can be set at the first end of the two first plates, and the second discharge device can be set between the two first plates and at the second end of the two first plates; that is, the high voltage electrode and the second discharge device are located at different ends of the first plates.

[0049] The two second plates of the second discharge device can be arranged opposite to each other and are parallel to each other; and the two second plates are parallel to the two first plates. The distance between the two first plates is greater than the distance between the two second plates, for example, the distance between the two first plates is 10-20 mm and the distance between the two second plates is 3-5 mm. This embodiment of the invention does not impose such limitations.

[0050] The plate-shaped discharge electrode of the second discharge device can be located between two second plates and parallel to each of the two second plates. The plate-shaped discharge electrode can be connected to a second power source, which can supply power to the plate-shaped discharge electrode so that a stable electric field can be formed between the second plates and the plate-shaped discharge electrode. This allows for a second dust collection in the dust collection area through the plate-shaped discharge electrode and the electric field. Figure 1b As shown; moreover, the plate-shaped discharge electrode can convert oxygen in the air to obtain ozone for sterilization and disinfection of the low-temperature storage environment.

[0051] As an example, a low-temperature storage environment can be a cold and humid environment; ozone can combine with water vapor in the environment to form ozone water, which can then be used to sterilize and disinfect the surface of objects.

[0052] In practical applications, the electrode plates are made of metal; when the edges of the electrode plates are too sharp, there may be edge-limited discharge problems; and due to the large variability in the roughness of the metal surface, or due to process factors causing the metal surface to be sharp, arcing problems may also occur; in order to avoid the above problems, in one embodiment of the present invention, the first electrode plate and the second electrode plate are wrapped with a composite insulating material.

[0053] Specifically, a layer of composite insulating material, such as organosilicon or silicone, can be included on the outside of the first and second electrodes. By wrapping the first and second electrodes with the composite insulating material, on the one hand, the smoothness of the first and second electrodes can be improved and the roughness of the first and second electrodes can be reduced, making the first and second electrodes smoother; on the other hand, the electric field strength of the first electrode and the second discharge device can be weakened, avoiding energy concentration; furthermore, the electrodes are easier to maintain after being covered with the composite insulating material, and electrochemical corrosion of the electrodes can be avoided.

[0054] In one embodiment of the present invention, the second power source is an AC power source.

[0055] Specifically, the second power source can be an AC power source; thus, by changing the second power source, the polarity of the second plate and the plate-shaped discharge electrode can be adjusted according to the discharge frequency of the second power source; for example, when the output of the second power source makes the plate-shaped discharge electrode a positive high voltage potential, the two second plates are at ground potential; conversely, if the output of the second power source makes the plate-shaped discharge electrode a ground potential, the two second plates are at a positive high voltage potential.

[0056] As an example, the AC power supply of the second power source can be an AC DBD (Dielectric Barrier Discharge) power supply, and this embodiment of the invention does not limit this.

[0057] In practical applications, high concentrations of ozone may harm human health. To avoid ozone used for sterilization and disinfection in low-temperature storage environments from harming the health of people entering the low-temperature storage environment, the above-mentioned equipment may also include a reduction device, which can be used to reduce ozone in the low-temperature storage environment to oxygen.

[0058] Specifically, the aforementioned equipment may further include a reduction device, which includes a reduction grid and a fan; the reduction grid is used to reduce the ozone generated by the first discharge device and the second discharge device into oxygen; the fan is used to blow the ozone toward the reduction grid.

[0059] The fan can be used to blow air from the low-temperature storage environment toward the reduction network, thereby blowing the ozone generated by the first and second discharge devices in the low-temperature storage environment toward the reduction network; the ozone blown toward the reduction network will be reduced into oxygen by the reduction network.

[0060] As an example, the reduction network may include a target catalyst for converting ozone into oxygen.

[0061] Specifically, a reduction network can be formed using a target catalyst for converting ozone into oxygen; wherein the target catalyst can be a halogen atom, and the embodiments of the present invention are not limited thereto.

[0062] In practical applications, the above-mentioned equipment can be installed at the return air vent of the air conditioner's cold storage or refrigerator; to avoid the risk of electric shock caused by accidental contact, a fence can be installed to isolate people from the equipment, thereby preventing people from accidentally touching the equipment.

[0063] This invention provides a sterilization device for low-temperature storage environments, which may include a first discharge device and a second discharge device. The first discharge device can generate plasma and / or ozone, and the second discharge device can generate ozone. The plasma generated by the device can charge and collect particles in the low-temperature storage environment, thereby avoiding particle contamination of the stored environment. In addition, the ozone generated by the device can diffuse throughout the low-temperature storage environment, thereby eliminating microorganisms in the low-temperature storage environment and achieving a highly efficient sterilization effect on the low-temperature storage environment.

[0064] In addition, the first and second discharge devices can collect particles from the environment multiple times, thereby improving the dust removal effect.

[0065] In practical applications, different disinfection modes may be required for low-temperature storage environments, such as routine disinfection and deep disinfection. To make the above-mentioned equipment applicable to different scenarios, this embodiment of the invention also provides a sterilization method for low-temperature storage environments, referring to... Figure 2 The flowchart of the method is shown.

[0066] This method can be applied to the above-mentioned devices, which may include a daily disinfection mode and a deep disinfection mode;

[0067] Specifically, the method may include the following steps:

[0068] Step 201: In response to the first command, control the first power supply to start the daily disinfection mode of the device.

[0069] In practical applications, when routine disinfection of the low-temperature storage environment is required, a first command can be input to the device. The first command can be used to control the first power supply so that the device can sterilize and disinfect the low-temperature storage environment based on the routine disinfection mode.

[0070] Specifically, upon receiving the first instruction, the aforementioned device can respond to the first instruction by controlling the first power supply in order to activate the device's daily disinfection mode.

[0071] As an example, in response to a first command, the first power supply can be controlled to output a positive high voltage to the high voltage electrode.

[0072] After the first power source outputs a positive high voltage to the high-voltage electrode, the high-voltage electrode will also have a positive high voltage. At this time, the high-voltage electrode can release plasma to charge the particles in the low-temperature storage environment. The charged particles will be attracted to the first electrode by the electric field formed by the positive high voltage electrode and the first electrode plate, thus achieving the first dust collection.

[0073] In addition, the high-voltage electrode of the positive high voltage can also convert oxygen in the air; specifically, because positively charged particles have large mass and slow movement, their corona discharge range is small and the generation rate of active oxygen is low; thus, a small amount of ozone can be generated through the high-voltage electrode of the positive high voltage to carry out routine sterilization and disinfection of the low-temperature storage environment.

[0074] Step 202: In response to the second command, control the first power supply to activate the device's deep disinfection mode.

[0075] When deep disinfection of the low-temperature storage environment is required, a second command can be input to the device; the second command can be used to control the first power supply so that the device can sterilize and disinfect the low-temperature storage environment based on the deep disinfection mode.

[0076] Specifically, upon receiving the second instruction, the aforementioned device can respond to the second instruction by controlling the first power supply in order to activate the device's deep disinfection mode.

[0077] As an example, in response to a second command, the first power supply can be controlled to output a negative high voltage to the high voltage electrode.

[0078] After the first power source outputs a negative high voltage to the high-voltage electrode, the high-voltage electrode will also have a negative high voltage. At this time, the high-voltage electrode can release plasma to give the particles in the low-temperature storage environment a charge. The charged particles will be attracted to the first electrode by the electric field formed by the negative high voltage electrode and the first electrode plate, thus achieving the first dust collection.

[0079] In addition, the high-voltage electrode of the negative high voltage can also convert oxygen in the air; specifically, because positively charged particles have small mass and fast movement, their corona discharge range is large and they easily combine with oxygen molecules; thus, a large amount of ozone can be generated through the high-voltage electrode of the negative high voltage to deeply sterilize and disinfect the low-temperature storage environment.

[0080] In one embodiment of the present invention, when sterilizing and disinfecting the low-temperature storage environment, the second power source can supply power to the plate-shaped discharge electrode so that a stable electric field can be formed between the second plate and the plate-shaped discharge electrode, thereby performing a second dust collection through the plate-shaped discharge electrode and the electric field; and the plate-shaped discharge electrode can convert oxygen in the air to obtain ozone for sterilizing and disinfecting the low-temperature storage environment.

[0081] In this embodiment of the invention, the device can respond to a first instruction to control the first power supply to activate the device's daily disinfection mode; and respond to a second instruction to control the first power supply to activate the device's deep disinfection mode. Through this embodiment of the invention, the device can be adapted for disinfection in different scenarios.

[0082] It should be noted that, for the sake of simplicity, the method embodiments are all described as a series of actions.

[0083] The following is a specific example to illustrate the above-mentioned equipment and method:

[0084] like Figure 3 As shown, the device can be divided into daily disinfection mode and deep disinfection mode. When the user turns on the device, he / she can enter the corresponding command to activate the different modes of the device. The daily disinfection mode can be used for storage during busy farming seasons, while the deep disinfection mode can be used for use during slack farming seasons.

[0085] When using the daily disinfection mode, the first power supply can be controlled to output a positive high voltage to the high voltage electrode; at this time, the first discharge device will be in a low-concentration ozone generation mode; the low-concentration ozone can be used to sterilize and disinfect the low-temperature storage environment; the first discharge device can also generate plasma to collect dust in the air to purify the air.

[0086] When using the deep disinfection mode, the first power supply can be controlled to output a negative high voltage to the high voltage electrode; at this time, the first discharge device will be in a high-concentration ozone generation mode (for example, the ozone concentration can be controlled at 5~10ppm in a short time); the high concentration of ozone can be used to sterilize and disinfect the low-temperature storage environment; the first discharge device can also generate plasma to collect dust in the air to purify the air.

[0087] Reference Figure 4The diagram shows a structural schematic of a sterilization device for low-temperature storage environment according to an embodiment of the present invention. The device can be applied to the above-mentioned equipment and may include a daily sterilization mode and a deep sterilization mode.

[0088] Specifically, the device may include the following modules:

[0089] The daily disinfection module 401 is used to control the first power supply in response to the first command, so as to start the daily disinfection mode of the device;

[0090] The deep disinfection module 402 is used to control the first power supply in response to the second command, so as to start the deep disinfection mode of the device.

[0091] In an optional embodiment of the present invention, the daily disinfection module 401 is used to control the first power supply to output a positive high voltage to the high voltage electrode in response to a first instruction;

[0092] The deep disinfection module 402 is used to respond to the second command and control the first power supply to output negative high voltage to the high voltage electrode.

[0093] In this embodiment of the invention, the device can respond to a first instruction to control the first power supply to activate the device's daily disinfection mode; and respond to a second instruction to control the first power supply to activate the device's deep disinfection mode. Through this embodiment of the invention, the device can be adapted for disinfection in different scenarios.
