The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0031] The inventors discovered that relatively enclosed spaces such as trains, cars, and restrooms have poor air circulation, and that conventional methods of disinfecting object surfaces produce irritating odors.

[0032] To address the aforementioned issues, the applicant proposes a portable multifunctional plasma sterilization device according to embodiments of this application, comprising: a plasma ionization device 1, a power supply device 5, a compression device 2, and an oxygen generating device 3.

The air inlet of the oxygen generating device 3 is connected to the air outlet of the compression device 2 to store the gas transmitted through the compression device 2. The air outlet of the oxygen generating device 3 releases oxygen from the gas. Surface disinfection is performed using plasma, and the generated ozone is decomposed into oxygen through compression. Simultaneously, the air is pressurized, and after separation, pure oxygen is collected. This solves the problem of surface aging and corrosion caused by commercial disinfection methods, as well as the problems of surface odor generation and VOC volatilization. It also provides fresh oxygen for enclosed, densely populated areas, improving the user experience. The portable multifunctional plasma sterilization device will be described in detail in the following embodiments.

[0033] The following is combined Figure 1 and Figure 2 The portable multifunctional plasma sterilization device provided in the embodiments of this application is described below:

[0034] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of a portable multifunctional plasma sterilization device provided in this application embodiment. In this embodiment, the portable multifunctional plasma sterilization device may include a plasma ionization device 1, a power supply device 5, a compression device 2, and an oxygen generation device 3.

[0035] The plasma ionization device 1 includes a first electrode layer 11, an insulating layer 12, and a second electrode layer 13 stacked sequentially. The first electrode layer 11 can be a grounded electrode, the second electrode layer 13 can be a high-voltage electrode, and the insulating layer 12 is a high-voltage, high-temperature resistant insulating sheet. (See attached diagram.) Figure 1The power supply device 5 connects the first electrode layer 11 to the low-voltage end of the power supply device 5 and the second electrode layer 13 to the high-voltage end of the power supply device 5. It is used for plasma surface discharge and collection of odors, VOCs, etc. on the surface of objects. When the power is on, the high-voltage electrode plate and the ground electrode plate have a high-voltage AC high-frequency discharge gap, which ionizes the air and produces uniform glow discharge. The high-energy plasma can produce etching, radiation and active groups to inactivate bacteria and viruses. At the same time, it can also break the molecular bonds of odor molecules and VOCs, decomposing them into carbon dioxide and water.

[0036] The electrode layer can be selected from DBD plasma discharge sheets.

[0037] The air inlet of the compression device 2 is connected to the second electrode layer 13 to obtain the gas transmitted through the through hole 6 and compress it to the air outlet of the compression device 2. The air inlet of the oxygen generating device 3 is connected to the air outlet of the compression device 2 to store the gas transmitted through the compression device 2. The air outlet of the oxygen generating device 3 releases the oxygen in the gas. The sterilized and disinfected air enters the oxygen generating device 3 from the compression device 2.

[0038] In this embodiment of the application, the plasma generated by the plasma ionization device 1 can effectively kill microorganisms such as bacteria, viruses and fungi in the air. The device can remove odors, formaldehyde and other harmful gases and volatile organic compounds from the surface of objects. The oxygen generating device 3 can obtain gas from the compression device 2 and release oxygen, which is suitable for some scenarios that require additional oxygen supply.

[0039] It should be noted that a switch can be installed on the power supply device 5 to control the operation and start-up of this device.

[0040] In one embodiment, the portable multifunctional plasma sterilization device further includes:

[0041] The filter device 4 includes a gas screening device 41 and a gas release valve 42. The inlet end of the gas screening device 41 is connected to the outlet of the compression device 2, and the outlet end of the gas screening device 41 is connected to the inlet of the oxygen generating device 3. The gas release valve 42 is located on the top of the gas screening device 41.

[0042] In this embodiment, after the DBD plasma discharge sheet discharges, it breaks down the air, collects oxygen atoms to generate a large amount of ozone. As the air passes through the compression device 2, the ozone decomposes into oxygen molecules due to pressure. The oxygen and nitrogen-containing mixed gas are compressed and pressurized before entering the gas screening device 41. Under a certain pressure, the gas screening device 41 absorbs nitrogen and separates oxygen, which is stored in the oxygen generating device 3 and discharged when the usage requirements are met or the gas is full.

[0043] When nitrogen is saturated, the gas release valve 42 located at the top can release the pressure, and the nitrogen will be automatically released, so that the gas screening device 41 can be reused.

[0044] In one embodiment, the gas screening device 41 includes a molecular sieve for collecting nitrogen gas from the gas compressed by the compressor 22, and the nitrogen gas from the gas compressed by the compressor 22 is transferred from the molecular sieve to the oxygen generating device 3.

[0045] In this embodiment, the molecular sieve in the gas screening device 41 can effectively filter nitrogen in the gas compressed by the compressor 22. The inlet end of the screening device 21 is connected to the outlet of the compressor 2, and the outlet end of the screening device 21 is connected to the inlet of the oxygen generating device 3. The gas release valve 42 is set on the top of the gas screening device 41, which can realize the flow direction control of nitrogen. The gas screening device 41 can ensure the purity of oxygen and improve the working efficiency of the oxygen generating device 3. This allows for more effective storage and release of oxygen, providing a high-quality oxygen supply.

[0046] In one embodiment, the compression device 2 includes an air intake device 21 and a compressor 22. The air intake port of the air intake device 21 is connected to the second electrode layer 13, the air outlet of the air intake device 21 is connected to the air intake port of the compressor 22, and the air outlet of the compressor 22 is connected to the gas screening device 41.

[0047] In this embodiment, as air passes through the oil-free compressor 22, ozone decomposes into oxygen molecules due to pressure. The oxygen and nitrogen-containing mixture enters the compression device 2 through the air intake device 21. The air intake device 21 may include an air pump or other suction device, with its outlet facing the air intake of the compressor 22. The air intake device 21 can be, but is not limited to, other power sources. After being pressurized by the compressor 22, the air enters the molecular sieve. Under a certain pressure, the molecular sieve absorbs nitrogen and separates oxygen, which is then stored in the oxygen generation device 3.

[0048] In one embodiment, the oxygen generating device 3 includes an oxygen storage device 31 and a power unit 32. The oxygen storage device 31 is used to collect oxygen filtered by a molecular sieve, and the power unit 32 is disposed above the oxygen storage device 31.

[0049] In this embodiment, the oxygen storage device 31 serves as a buffer, slowly storing the compressed oxygen in the storage tank. The power equipment 32 at the oxygen production outlet can be configured with various types of power, such as a fan-type power, like a centrifugal fan or an axial fan.

[0050] In this embodiment of the application, the device uses plasma for surface disinfection, and the generated ozone is decomposed into oxygen by compression. At the same time, the air is pressurized and then separated by a molecular sieve, and the pure oxygen is collected.

[0051] In one embodiment, the power supply device 5 includes: a high-voltage AC power supply device, the low-voltage end of which is connected to the first electrode layer 11, and the high-voltage end of which is connected to the second electrode layer 13.

[0052] Specifically, when operating under alternating current, the high-voltage electrode plate and the grounding electrode plate have a high-voltage alternating high-frequency discharge gap, which ionizes the air to produce a uniform glow discharge. The high-energy plasma can generate etching, radiation, and active groups to inactivate bacteria and viruses.

[0053] It should be noted that the power supply device 5 may also include other DC or AC power supplies, which can supply power to the compressor device 2 and the oxygen generating device 3 by connecting to them, and provide power supplement to the air intake device 21, the compressor 22 and the power device 32.

[0054] Please see Figure 2 , Figure 2 This is a schematic diagram of the bottom structure of a plasma ionization device 1 provided in an embodiment of this application.

[0055] In one embodiment, the first electrode layer 11, the insulating layer 12, and the second electrode layer 13 are all provided with through holes 6.

[0056] In this embodiment, both the high-voltage electrode sheet and the grounding electrode sheet are conductive media, and the insulating sheet is not limited to any material (such as high-temperature resistant silicone, ceramic, quartz, etc.). After the three insulating sheets are overlapped, multiple ventilation holes are penetrated in the middle for plasma surface discharge and collection of odors, VOCs, etc. from the surface of objects.

[0057] In one embodiment, the through-hole 6 is uniformly distributed through the superimposed first electrode layer 11, insulating layer 12 and second electrode layer 13.

[0058] In this embodiment, the through holes 6 are uniformly distributed through the first electrode layer 11, the insulating layer 12, and the second electrode layer 13. This design allows the plasma discharge to be evenly distributed throughout the entire effective area of ​​the device, improving the uniformity and comprehensiveness of the sterilization effect.

[0059] The ability of gas to flow between the first electrode layer 11, the insulating layer 12, and the second electrode layer 13 ensures gas circulation within the device and promotes the normal operation of the plasma sterilization device.

[0060] In one embodiment, the air intake device 21 includes an air pump or a suction device.

[0061] In one embodiment, the insulating layer 12 is made of a non-conductive material, including: ceramic quartz.

[0062] In this embodiment, after the DBD plasma discharge sheet discharges, it breaks down the air, collecting oxygen atoms to generate a large amount of ozone. As the air passes through the oil-free compressor 22, the ozone decomposes into oxygen molecules due to pressure. The oxygen and nitrogen-containing gas mixture is then compressed and pressurized before entering the molecular sieve. Under a certain pressure, the molecular sieve absorbs the nitrogen while separating the oxygen, which is stored in an oxygen storage tank and discharged by a power unit. When the nitrogen is saturated, the pressure can be released, and the nitrogen is automatically released, allowing the molecular sieve to be reused.

[0063] This device can achieve disinfection and oxygen generation effects with only power consumption. It has a good effect on air purification, surface odors, organic waste gas, and existing surface bacteria, while generating oxygen and discharging it into a relatively enclosed space.

[0064] In this embodiment, the device generates plasma, which, through its bactericidal properties, effectively kills bacteria, viruses, and other microorganisms in the air. The reactive oxygen species and other chemicals released by the plasma destroy the cell membranes and nucleic acid structures of bacteria and viruses, thus achieving the effect of killing pathogens. The device is equipped with a filter 4, which can screen and filter the gas entering the device, effectively filtering out nitrogen and oxygen, and storing them separately to provide pure oxygen for human use. The device is designed to be portable, convenient to carry and use, and suitable for different places and environments. People can carry it with them whenever needed to purify and sterilize the air, improving air quality and hygiene.

[0065] It plays a positive role in improving indoor air quality, preventing the spread of infectious diseases, and providing a clean oxygen supply.

[0066] Working Process: When disinfection of items needs to be cleaned, the portable multi-functional plasma sterilization device is placed on the surface of the item to be cleaned. The plasma ionization device 1 contacts the surface of the item. The low-voltage end of the high-voltage AC power supply is connected to the first electrode layer 1 of the plasma ionization device 1, and the high-voltage end of the high-voltage AC power supply is connected to the second electrode layer 13 of the plasma ionization device 1. The high-voltage AC power supply device can be equipped with a start switch to control its start-up operation. After starting and operating, the high-frequency discharge gap of the high-voltage AC power supply ionizes the air to produce a uniform glow discharge, and the high-energy plasma can... The device generates etching, radiation, and active groups to inactivate bacteria and viruses on the surface of the object. At the same time, it can break the molecular bonds of odor molecules and VOCs, causing them to decompose into carbon dioxide and water. At this time, after the DBD plasma discharge sheet discharges, it breaks down the air, collects oxygen atoms, and generates a large amount of ozone. The ozone, along with the remaining air, enters the compression device 2 through the through holes 6 that are uniformly distributed on the superimposed first electrode layer 11, insulating layer 12, and second electrode layer 13. The power supply device 5 may also include other power supply equipment, which can supply power to the compression device 2 and the oxygen generating device 3. During the power-on process, the air intake device 21 in the compression device 2 starts working. It can use an air pump or a suction (fan) to draw the gas from the surface of the object contacted by the first electrode layer 11 into the air intake device 21 through the through hole 6. The air intake device 21 introduces the air into the compressor 22 for compression. During this process, the ozone carried in the air decomposes into oxygen molecules due to the pressure. The oxygen molecules and some nitrogen-containing mixed gas are compressed and pressurized together and then enter the filter device 4. The gas screening device 41 in the filter device 4 absorbs the nitrogen in the mixed gas, and the remaining oxygen flows into the oxygen generating device 3. The oxygen generating device 3 is equipped with an oxygen storage device 31 to store oxygen. In addition, the oxygen generating device 3 is also equipped with a power device 32, which can include various types of fans or gas guiding devices. It can be equipped with a separate power supply and control switch. When the user needs to use it in a crowded and poorly ventilated environment, the device is triggered to generate oxygen. In addition, when the nitrogen storage in the gas screening device 41 is full, the gas release valve 42 located above the gas screening device 41 can automatically remove the excess nitrogen.

[0067] This device can achieve disinfection and oxygen generation simply by being powered. It has a good effect on purifying the air, eliminating and inactivating odors, organic waste gases, and surface bacteria. At the same time, the oxygen generated can be discharged into a relatively enclosed space.
