Technical Field

[0002] As the quality of life continues to improve, users' requirements for products are getting higher and higher. This is especially true in the home appliance industry, where traditional functions can no longer meet user needs. For example, for indoor air disinfection, traditional air disinfection is carried out through circulating gas, but the sterilization efficiency is relatively low, and it can only disinfect the air in unmanned areas indoors, which is also prone to secondary pollution. Therefore, how to achieve a safe and efficient disinfection process without regional restrictions has become an urgent problem to be solved in the home appliance industry.

[0003] With the continuous breakthroughs in plasma technology, this technology is increasingly favored by various industries. Plasma technology has been applied to industries such as medical equipment, food preservation, and agricultural disinfection, and has played a very critical role. Since plasma activated mist has a strong disinfection function and can dynamically disinfect indoor air when people are present, it does not harm people and objects and does not cause secondary pollution to the environment. It has been increasingly used in the home appliance industry. However, in the existing plasma activated mist disinfection system, the activated mist reaction device has a non-compact structure and a relatively large volume, which is not conducive to the miniaturization of the product, and the discharge area is relatively small, and the preparation efficiency of plasma activated mist is low. Utility Model Content

[0004] In view of this, the utility model provides an activated mist reaction device and an air disinfection system to solve the problems in the prior art that the activated mist reaction device has a non-compact structure, a relatively large volume, a relatively small discharge area, and a low efficiency in preparing plasma activated mist.

[0007] The plasma generating unit comprises an electrode structure arranged in the shell, the electrode structure is wound into a vortex shape, and the electrode structure is used to ionize the air in the shell to form plasma;

[0008] The plasma generated by the discharge of the electrode structure is mixed with the atomizing gas entering the shell from the atomizing gas inlet to generate plasma activated mist.

[0009] Beneficial effects: By setting the electrode structure of the plasma generating unit to a vortex shape, the structure of the plasma generating unit is made more compact, which is more conducive to the miniaturized design of the product. Compared with the traditional flat, cylindrical, and needle-shaped electrode structures, the spiral electrode structure is not only more compact, but also has a larger effective processing area per unit time and a larger discharge area, which can effectively improve the mixing efficiency of plasma and atomized gas, thereby improving the preparation efficiency of activated mist, thereby improving the sterilization efficiency, and effectively solving the problems in the prior art that the activated mist reaction device has a non-compact structure, a relatively large volume, a relatively small discharge area, and a low preparation efficiency of plasma activated mist.

In addition, according to the dielectric barrier discharge, the discharge area is directly proportional to the concentration of the generated plasma, that is, the larger the discharge area, the more plasma is generated under the same conditions. The present application can maximize the discharge area of ​​the electrode structure within a limited space by arranging the electrode structure in a vortex shape, and by arranging two second electrodes on both sides of the first electrode, discharge can be performed on both sides of the electrode structure, and the discharge area is doubled, thereby doubling the preparation efficiency of the activated mist.

The second activated mist outlet adopts a design of several air outlet holes, which can make the plasma activated mist spray out evenly in a mist form, and the sterilization effect is better.

[0036] In an optional embodiment, the plasma generating unit further comprises:

[0037] The AC power supply is located in the shell, the electrode structure is connected to the AC power supply, and the AC power supply and the electrode structure are integrated.

[0074] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0075] Combine the following Figures 1 to 12 , describing an embodiment of the utility model.

[0076] According to an embodiment of the present utility model, on the one hand, combined with Figures 1 to 10 As shown, the utility model provides an activated mist reaction device 20, comprising: a shell 21 and a plasma generating unit 22, the shell 21 having an atomizing gas inlet and an activated mist outlet; the plasma generating unit 22 comprises an electrode structure 221 arranged in the shell 21, the electrode structure 221 is wound into a vortex shape, and the electrode structure 221 is used to ionize the air in the shell 21 to form plasma; the plasma generated by the discharge of the electrode structure 221 is mixed with the atomizing gas entering the shell 21 from the atomizing gas inlet to generate plasma activated mist.

[0077] In the above embodiment, by setting the electrode structure 221 of the plasma generating unit 22 to a vortex shape, the structure of the plasma generating unit 22 is made more compact, which is more conducive to the miniaturized design of the product. Compared with the traditional flat, cylindrical, and needle-shaped electrode structures, the spiral electrode structure 221 is not only more compact in structure, but also has a larger effective processing area per unit time and a larger discharge area, which can effectively improve the mixing efficiency of plasma and atomized gas, thereby improving the preparation efficiency of activated mist, thereby improving the sterilization efficiency, and effectively solving the problem that the activated mist reaction device 20 in the prior art has a non-compact structure, a relatively large volume, a relatively small discharge area, and a low preparation efficiency of plasma activated mist.

[0078] Specifically, a chamber is provided in the shell 21, and an atomizing gas inlet and an activated mist outlet are respectively connected to the chamber of the shell 21, wherein the atomizing gas inlet is used to supply atomizing gas to enter the shell 21, and the electrode structure 221 can utilize high-voltage alternating current to break through the air in the shell 21 to form plasma. The plasma generated by the discharge of the electrode structure 221 can be mixed with the atomizing gas entering from the atomizing gas inlet to generate activated mist, which is then discharged from the activated mist outlet for disinfecting the air.

[0079] In some embodiments, in combination Figures 1 to 5 As shown, the electrode structure 221 includes a first electrode 2211 , a second electrode 2212 , and an insulating dielectric layer 2213 . There are two second electrodes 2212 , and the two second electrodes 2212 are distributed on both sides of the first electrode 2211 . The insulating dielectric layer 2213 is disposed between the first electrode 2211 and the second electrode 2212 .

[0080] In the above embodiment, the electrode structure 221 can form a dielectric barrier discharge by adopting the design of the first electrode 2211, the second electrode 2212, and the insulating dielectric layer 2213, and after applying a certain voltage between the first electrode 2211 and the second electrode 2212, a large amount of strong electric field will be generated between the two electrodes, thereby ionizing and breaking down the air, and then generating plasma. In addition, according to the dielectric barrier discharge, the discharge area is proportional to the concentration of the generated plasma, that is, the larger the discharge area, the more plasma is generated under the same conditions. The present application can maximize the discharge area of ​​the electrode structure 221 within a limited space by setting the electrode structure 221 in a vortex shape, and by setting two second electrodes 2212 on both sides of the first electrode 2211, discharge can be performed on both sides of the electrode structure 221, and the discharge area is doubled, thereby doubling the preparation efficiency of the activated mist.

[0081] Specifically, the electrode structure 221 includes a first electrode 2211, two second electrodes 2212 and an insulating dielectric layer 2213, and there is a set potential difference between the first electrode 2211 and the second electrode 2212. One of the first electrode 2211 and the second electrode 2212 is connected to the high voltage end of the AC power supply, and the other is connected to the low voltage end, or, it can also be said that one of the first electrode 2211 and the second electrode 2212 is connected to the positive pole of the AC power supply and the other is connected to the negative pole, or, it can also be said that one of the first electrode 2211 and the second electrode 2212 is connected to the high voltage end of the AC power supply and the other is grounded. Optionally, the first electrode 2211 is connected to the low voltage end of the AC power supply, and the second electrode 2212 is connected to the high voltage end of the AC power supply.

[0082] Furthermore, since the second electrode 2212 is exposed to the environment for a long time during operation and the discharge process will produce highly oxidizing particles, the second electrode 2212 should consider using a conductive material with high corrosion resistance and not easy to oxidize when selecting the material, such as stainless steel or titanium alloy. The first electrode 2211 is hidden in the insulating dielectric layer 2213, and the material performance requirements of the first electrode 2211 are conductive metals, such as copper and aluminum. Of course, the first electrode 2211 can also use metal materials such as stainless steel or titanium alloy. The insulating dielectric layer 2213 is the dielectric layer required for discharge, and its material can be selected from a flexible insulating material with strong electrical breakdown resistance, high corrosion resistance and not easy to oxidize.

[0083] In some embodiments, in combination Figures 3 to 5 As shown, a plurality of through holes 22120 are defined on the second electrode 2212 .

[0084] In the above embodiment, since a large amount of air is required to participate in the reaction during the discharge of the plasma generating unit 22 to generate plasma, that is, the larger the contact area between the second electrode 2212 and the air, the more plasma is generated. Therefore, the present application forms a porous structure of the second electrode 2212 by opening a plurality of through holes 22120 on the second electrode 2212, which can further increase its discharge area, thereby increasing the plasma output and further improving the preparation efficiency of the activated mist.

[0085] In some embodiments, the first electrode 2211 and the second electrode 2212 are both strip-shaped conductive sheets; the insulating dielectric layer 2213 wraps around the first electrode 2211 , and the two second electrodes 2212 are correspondingly attached to and fixed on the outside of the insulating dielectric layer 2213 on both sides of the first electrode 2211 .

[0086] In the above embodiment, the first electrode 2211 and the second electrode 2212 are configured as strip-shaped conductive sheets for easy winding, and the two second electrodes 2212 are fitted and fixed to the outside of the insulating medium layer 2213 located on both sides of the first electrode 2211, so that the entire electrode structure 221 forms a sandwich structure, i.e., the first electrode 2211-insulating medium layer 2213-second electrode 2212, and the structure is more compact.

[0087] Specifically, the first electrode 2211 and the second electrode 2212 are both strip-shaped metal sheets, and the insulating medium layer 2213 can completely wrap the first electrode 2211, and then the first electrode 2211 is connected through one end of the lead, and the other end passes through the insulating medium layer 2213 to connect to the low voltage end of the AC power supply or ground.

[0088] Furthermore, the first electrode 2211 has two shaped side surfaces that are opposite to each other, and the two second electrodes 2212 are fixed outside the insulating medium layer 2213 outside the two shaped side surfaces of the first electrode 2211 .

[0089] Optionally, the second electrode 2212 is bonded and fixed on the outer surface of the insulating dielectric layer 2213 .

[0090] In some embodiments, in combination Figure 1 , Figures 6 to 10 As shown, the inner cavity of the shell 21 is divided into two chambers, and the electrode structure 221 is movably arranged between the two chambers; the chamber includes a first chamber 211 and a second chamber 212, and the atomization gas inlet includes a first atomization gas inlet 2111 arranged on the first chamber 211 and a second atomization gas inlet 2121 arranged on the second chamber 212; the activated mist outlet includes a first activated mist outlet 2112 arranged on the first chamber 211 and a second activated mist outlet 2122 arranged on the second chamber 212; the first atomization gas inlet 2111 is arranged at the top or bottom of the first chamber 211, and the first activated mist outlet 2112 is arranged on the side of the first chamber 211; one of the second atomization gas inlet 2121 and the second activated mist outlet 2122 is arranged at the top of the second chamber 212, and the other is arranged at the bottom of the second chamber 212.

[0091] In the above embodiment, by dividing the inner cavity of the shell 21 into a first chamber 211 and a second chamber 212, and different chambers adopt the above-mentioned design of atomizing gas inlet and activated mist outlet at different positions, the flow path lengths of the atomizing gas in the two chambers can be made different, so that activated mist with different mixing efficiency and sterilization efficiency can be prepared to meet the needs of different scenarios, and by movably setting the electrode structure 221 between the two chambers, switching between different modes is convenient, so that a balance between efficient sterilization and low energy consumption can be taken into account, and the purpose of efficient energy saving can be achieved while meeting the sterilization efficiency.

[0092] Specifically, in this embodiment, the first atomizing gas inlet 2111 is arranged at the top or bottom of the first chamber 211, and the first activated mist outlet 2112 is arranged on the side of the second chamber 212. When the vortex-shaped electrode structure 221 is located in the first chamber 211, after the atomizing gas enters from the first atomizing gas inlet 2111, it can enter the vortex channel 2210 from the upper and lower ends of the vortex channel 2210 formed by the vortex-shaped electrode structure 221, and follow the vortex trajectory of the vortex channel 2210. After fully contacting and mixing with the plasma in the vortex channel 2210, it flows from the end of the vortex channel 2210 to the first activated mist outlet 2112, and then is discharged from the first activated mist outlet 2112. The atomizing gas has a spiral flow trajectory in the first chamber 211, with a longer residence reaction time and more complete mixing with the plasma, so that the prepared plasma activated mist has a higher concentration, a better sterilization effect, and is more suitable for a deep disinfection mode.

[0093] Furthermore, the second atomizing gas inlet 2121 and the second activated mist outlet 2122 located in the second chamber 212 adopt a vertical straight-through design. After entering the second chamber 212, the atomizing gas directly passes through the upper and lower ends of the vortex channel of the electrode structure 221. The atomizing gas goes straight in and out, and the reaction time with the plasma generated by the electrode structure 221 is short, so the concentration of the prepared plasma activated mist is relatively low, which is more suitable for ordinary disinfection mode.

[0094] Preferably, in this embodiment, the first chamber 211 and the second chamber 212 are arranged left and right.

[0095] In some embodiments, in combination Figure 1 , Figure 2 , Figures 6 to 8 As shown, the electrode structure 221 forms a vortex channel 2210, and the vortex channel 2210 has a rolling end located in the center and a tail end located on the periphery; the electrode structure 221 has a first working position located in the first chamber 211 and a second working position located in the second chamber 212; when the electrode structure 221 is located at the first working position, the first atomizing gas inlet 2111 corresponds to the rolling end in the center of the vortex channel 2210, and the tail end of the vortex channel 2210 faces the first activated mist outlet 2112.

[0096] In the above embodiment, the first atomizing gas inlet 2111 is arranged at the center position of the top or bottom of the first chamber 211, and corresponds to the rolling end in the center of the vortex channel 2210, so that when the vortex-shaped electrode structure 221 is located in the first chamber 211, the entering atomizing gas can enter the vortex channel from the rolling end in the center of the electrode structure 221, and then be discharged from the tail end of the vortex channel 2210 to the first activated mist outlet 2112, and be discharged from the first activated mist outlet 2112. Through the above design, the atomizing gas can flow from the rolling end to the end of the vortex channel, through the entire vortex channel, and the flow path is the longest, thereby maximizing the reaction time between the atomizing gas and the plasma and increasing the concentration of the plasma activated mist.

[0097] Preferably, in this embodiment, the first atomizing gas inlet 2111 and the second atomizing gas inlet 2121 are located on the same side of the shell 21. For example, when the first atomizing gas inlet 2111 is arranged at the top of the first chamber 211, the second atomizing gas inlet 2121 is also arranged at the top of the second chamber 212; when the first atomizing gas inlet 2111 is arranged at the bottom of the first chamber 211, the second atomizing gas inlet 2121 is also arranged at the bottom of the second chamber 212. By arranging the first atomizing gas inlet 2111 and the second atomizing gas inlet 2121 on the same side, it is convenient to connect with the outlet end of the atomizing device 10 later.

[0098] In some embodiments, the plasma generating unit 22 is slidably connected in the shell 21, and the activated mist reaction device 20 also includes a first driving mechanism, which is connected to the electrode structure 221 and is suitable for driving the electrode structure 221 to move between the first working position and the second working position.

[0099] In the above embodiment, the design of the sliding plasma generating unit 22 facilitates the adjustment of its position in the shell 21. The first driving mechanism is provided to facilitate the automatic switching of the activated mist reaction device 20 between different disinfection modes, which has a higher degree of automation and intelligence.

[0100] Specifically, the plasma generating unit 22 can be slidably connected in the shell 21 by means of a slide rail or a slide groove. Preferably, it can also be guided and limited by structures such as balls and guide wheels. The first driving mechanism can adopt a motor or an electric push rod. The first driving mechanism can be installed inside the shell 21 or outside the shell 21. Preferably, the first driving mechanism is installed outside the shell 21 and does not occupy the internal space of the shell 21.

[0101] Optionally, in this embodiment, the plasma generating unit 22 also includes an electrode terminal plate 222, and the electrode terminal plates 222 have two electrodes, which are arranged on both sides of the electrode structure 221. The electrode terminal plates 222 are integrated with the electrode structure 221, and the electrode terminal plates 222 are slidably connected in the shell 21, thereby ensuring that the plasma generating unit 22 remains connected to the shell 21 when switching modes.

[0102] In some embodiments, in combination Figure 1 , Fig. 9 , Fig.10 As shown, the top or bottom of the second chamber 212 is open to form a second atomizing gas inlet 2121 ; the second activated mist outlet 2122 includes a plurality of gas outlet holes opened on the bottom or top of the second chamber 212 .

[0103] In the above embodiment, the second atomizing gas inlet 2121 is formed by opening the top or bottom of the second chamber 212. The opening area of ​​the second atomizing gas inlet 2121 is larger, which is convenient for more atomizing gas to enter. The second activated mist outlet 2122 adopts a design of several small air outlet holes, which can make the plasma activated mist spray out evenly in a mist form, and has a better sterilization effect.

[0104] Specifically, in this embodiment, the shell 21 is a rectangular box body, and a barrier 210 is arranged in the middle of the rectangular box body to separate it into a first chamber 211 and a second chamber 212. The first electrode 2211 and the second electrode 2212 are both strip-shaped conductive sheets, and the widths of the first electrode 2211 and the second electrode 2212 match the height of the rectangular shell 21. The axial direction of the vortex-shaped electrode structure 221 is consistent with the height direction of the shell 21. When the electrode structure 221 is in the second working position, the upper and lower ends of the vortex channel of the electrode structure 221 are respectively connected to the second atomization gas inlet 2121 and the second activated mist outlet 2122 on the upper and lower sides of the second chamber 212, and a plurality of air outlets can be opened on the top wall or bottom wall of the second chamber 212 along the vortex trajectory of the vortex channel to facilitate the discharge of activated mist.

[0105] Optionally, in this embodiment, the first atomizing gas inlet 2111 is arranged on the bottom wall of the first chamber 211 , the second atomizing gas inlet 2121 is arranged on the bottom wall of the second chamber 212 , and the second activated mist outlet 2122 is arranged on the top wall of the second chamber 212 .

[0106] In other more preferred embodiments, the first atomizing gas inlet 2111 is arranged on the top wall of the first chamber 211, the second atomizing gas inlet 2121 is arranged on the top wall of the second chamber 212, and the second activated mist outlet 2122 is arranged on the bottom wall of the second chamber 212. With such a design, the plasma generating unit 22 can be slidably connected to the bottom walls of the first chamber 211 and the second chamber 212, thereby avoiding the second atomizing gas inlet 2121 being arranged on the bottom wall of the second chamber 212, which has a larger opening and will cause the plasma generating unit 22 to appear suspended.

[0107] In some embodiments, the plasma generating unit 22 further includes an AC power supply, which is located in the housing 21 , and the electrode structure 221 is connected to the AC power supply, and the AC power supply and the electrode structure 221 are integrated.

[0108] In the above embodiment, the AC power supply is arranged in the shell 21 and integrated with the electrode structure 221. When the driving mechanism adjusts the position of the electrode structure 221, the AC power supply can move with the electrode structure 221, thereby avoiding the problem that the AC power supply does not move, the line between it and the electrode structure 221 is pulled, and it is easy to be damaged, or it causes friction interference with other components, which poses a high safety hazard.

[0109] Optionally, in some specific embodiments, the AC power supply and the electrode structure 221 are fixed on the same mounting plate, and the mounting plate is slidably connected to the housing 21. Alternatively, in other embodiments, the AC power supply and the electrode structure 221 can be integrated in the same box body, and the box body is slidably connected to the housing 21. This embodiment does not limit the specific integration method of the AC power supply and the electrode structure 221, as long as the two can move synchronously.

[0110] In some embodiments, the activated mist reaction device 20 also includes a barrier 210 and a second driving mechanism, the barrier 210 has a barrier position that divides the inner cavity of the shell 21 into two chambers and an open position that connects the two chambers; the second driving mechanism is connected to the barrier 210 and is suitable for driving the barrier 210 to switch between the barrier position and the open position.

[0111] In the above embodiment, the shell 21 is divided into two chambers by the barrier 210, so that the two areas can be spatially independent and the independent airtightness of each chamber in different modes can be ensured. In addition, the barrier 210 can be driven to move between the barrier position and the open position by the second driving mechanism, so as to facilitate the adjustment of the position of the plasma generating unit 22 in the shell 21, so as to realize the switching of different modes according to different sterilization requirements.

[0112] For example, when it is necessary to switch from the normal disinfection mode to the deep disinfection mode, the second driving mechanism drives the barrier 210 to move to the open position, and then the first driving mechanism drives the plasma generating unit 22 to move from the second chamber 212 to the first chamber 211.

[0113] Optionally, the barrier 210 may be a sliding partition, a pull-out partition, a telescopic plate or a rolling shutter, and the second driving mechanism may be a motor, an electric push rod, a hydraulic cylinder, etc. Preferably, the second driving mechanism is installed outside the shell 21.

[0114] In some specific examples, combined with Figure 1 , Figures 6 to 10 As shown, the shell 21 is divided into two left and right areas, namely a first chamber 211 and a second chamber 212. The bottom surface of the first chamber 211 provided with a first atomizing gas inlet 2111 is set as surface a, and the side surface of the first chamber 211 provided with a first activated mist outlet 2112 is set as surface b. The bottom surface of the second chamber 212 provided with a second atomizing gas inlet 2121 is set as surface c, and the side surface of the second chamber 212 provided with a second activated mist outlet 2122 is set as surface d. The efficiency of activated mist generated by the electrode structure 221 in different areas is different.

[0115] like Figures 6 to 8 As shown, in the high-efficiency disinfection mode, when the electrode structure 221 is in the first chamber 211, the electrode structure 221 discharges in the first chamber 211 to generate plasma, and the atomized gas enters from the first atomized gas inlet 2111, and then flows from the center of the vortex-shaped electrode structure 221 along the vortex channel from the starting end to the tail end, and then is discharged from the first activated mist outlet 2112. The atomized gas flows in a vortex shape in the first chamber 211, and the flow path and residence time are longer, so it can be fully mixed with the plasma, and the prepared activated mist has a higher concentration and a better sterilization effect.

[0116] As attached Fig. 9 , Fig.10 As shown, in the normal disinfection mode, when the electrode structure 221 is in the second chamber 212, the atomized gas enters the second chamber 212 from the second atomized gas inlet 2121 on the c side, and then enters the vortex channel from the lower end of the vortex channel of the electrode structure 221, where the atomized gas mixes with the plasma to form an activated mist, and then is discharged from the upper end of the vortex channel, the second activated mist outlet 2122 on the d side, in a straight line.

[0117] It should be explained that the factors affecting the efficiency of preparing activated mist include the residence time of activated mist in the discharge area and the mixing efficiency. The efficiency of preparing activated mist and the concentration of activated mist in the first chamber 211 are higher than those in the second chamber 212. However, since the flow path of the atomized gas in the first chamber 211 is spiral and the flow path in the second chamber 212 is straight, the resistance in the first chamber 211 is greater than that in the second chamber 212, and more energy is required to overcome the resistance. Therefore, the resistance can be overcome by increasing the power of the atomized gas in the first chamber 211, for example, by combining Fig.11 As shown, the power of the airflow driving member 15 in the atomizing device 10 can be increased to increase the power of the atomized gas. In other alternative embodiments, an exhaust fan or the like can also be provided at the first activated mist outlet 2112. The activated mist in the high-efficiency disinfection mode has higher preparation efficiency and concentration, and better sterilization effect. The ordinary disinfection mode has a slightly lower sterilization effect than the high-efficiency disinfection mode, but requires less energy consumption. Therefore, different modes can be switched according to the needs of different places, taking into account the efficiency and low energy consumption of the activated mist preparation, so as to achieve the purpose of high efficiency and energy saving.

[0118] This embodiment provides a miniature and compact multi-mode activated mist reaction device 20, which can effectively improve the sterilization efficiency by adopting a spiral porous electrode structure 221 design. At the same time, different modes can be adjusted according to needs to achieve the purpose of improving the sterilization efficiency and saving energy consumption.

[0119] According to an embodiment of the present utility model, on the other hand, in combination Figure 1 , Fig.11 , Fig.12 As shown, an air disinfection system is provided, including an atomizing device 10, an activated fog reaction device 20 of any of the above-mentioned embodiments, and an automatic control device 30. The atomizing device 10 is used to convert liquid water into atomized gas, and the outlet end of the atomizing device 10 is connected to the atomized gas inlet of the activated fog reaction device 20; the automatic control device 30 is respectively connected to the atomizing device 10 and the activated fog reaction device 20, and is used to control the operation of the atomizing device 10 and the activated fog reaction device 20.

[0120] Optionally, an air outlet pipeline 16 is provided at the outlet end of the atomizing device 10, and the air outlet pipeline 16 includes a first air outlet pipeline and a second air outlet pipeline, the first air outlet pipeline is connected to the first atomizing gas inlet 2111, and the second air outlet pipeline is connected to the second atomizing gas inlet 2121, and the first air outlet pipeline and the second air outlet pipeline are respectively provided with switch valves.

[0121] In some embodiments, the air disinfection system has a normal disinfection mode and a deep disinfection mode; the activated mist reaction device 20 also includes a first driving mechanism connected to the electrode structure 221, and the shell 21 is divided into a first chamber 211 and a second chamber 212; when the air disinfection system starts the deep disinfection mode, the first driving mechanism drives the electrode structure 221 to move to a first working position located in the first chamber 211; when the air disinfection system starts the normal disinfection mode, the first driving mechanism drives the electrode structure 221 to move to a second working position located in the second chamber 212.

[0122] In the above embodiment, the automatic control device 30 of the air disinfection system can control the air disinfection system to switch between the deep disinfection mode and the ordinary disinfection mode according to the needs of different places, taking into account the effectiveness and low energy consumption of the activated mist preparation, and achieving the purpose of high efficiency and energy saving.

[0123] Exemplarily, when the user selects the deep disinfection mode, the automatic control device 30 controls the second driving mechanism to drive the barrier 210 between the first chamber 211 and the second chamber 212 to open, and the first driving mechanism drives the electrode structure 221 to move to the first working position in the first chamber 211. After the electrode structure 221 moves to the first working position, the second driving mechanism drives the barrier 210 to reset to the blocking position to ensure the independence of the first chamber 211 and the second chamber 212, and then controls the switch valve on the first air outlet duct to open, and the switch valve on the second air outlet duct to close, and finally, controls the atomization device 10 and the plasma generating unit 22 to start respectively to start preparing the activated mist.

[0124] In some embodiments, Fig.11 and Fig.12 As shown, the atomizing device 10 includes a housing 11 and a semiconductor condenser 12 and an atomizer 13 integrated in the housing 11. The semiconductor condenser 12 is used to condense air, and the atomizer 13 is used to convert liquid water condensed by the semiconductor condenser 12 into atomized gas.

[0125] In the above embodiment, the semiconductor condenser 12 is provided to directly obtain water vapor in the air for condensation to generate liquid water, and then the liquid water is atomized by the atomizer 13 to generate atomized gas, so that air sterilization can be achieved without manual water addition, which provides a better user experience and can also achieve the purpose of saving water. In addition, the semiconductor condenser 12 is smaller in size than the water tank, and the semiconductor condenser 12 and the atomizer 13 are integrated into a design to have a more compact structure, which is more conducive to the miniaturization of the product, and effectively solves the problem of the plasma activated mist preparation device in the prior art, in which the atomizer 10 is usually provided with a larger water tank, which not only requires manual water addition, but also causes the entire device to be large in size and inconvenient to install.

[0126] In some embodiments, the atomization device 10 further includes a guide structure 14 disposed between the semiconductor condenser 12 and the atomizer 13 , and configured to guide the liquid water condensed by the semiconductor condenser 12 to the atomizer 13 .

[0127] In the above embodiment, the guide structure 14 is provided to facilitate guiding and converging the liquid water condensed by the semiconductor condenser 12 to the atomizer 13 for atomization.

[0128] In some embodiments, the atomizer 13 is disposed obliquely below the semiconductor condenser 12 , and the guide structure 14 is obliquely connected between the semiconductor condenser 12 and the atomizer 13 , and the guide structure 14 includes a guide plate or a guide tube.

[0129] In the above embodiment, by arranging the atomizer 13 obliquely below the semiconductor condenser 12, and obliquely connecting the guide structure 14 between the semiconductor condenser 12 and the atomizer 13, the water flow can automatically converge into the atomizer 13 along the guide structure 14 under the action of gravity, and the obliquely arranged guide structure 14 can also speed up the flow rate of the water flow and improve the guide effect. Moreover, the guide structure 14 adopts the form of a guide plate or a guide tube, which has a simple structure and a good guide effect.

[0130] Optionally, the guide plate may adopt a plate-shaped structure with a V-shaped or U-shaped cross-section. The guide plate can prevent water from overflowing while guiding the flow by adopting a V-shaped plate or a U-shaped plate.

[0131] In some embodiments, the semiconductor condenser 12 includes a cooling end and a heating end, the cooling end is located inside the shell 11, and the heating end is located outside the shell 11; the guide plate is connected between the cooling end of the semiconductor condenser 12 and the atomizer 13.

[0132] In the above embodiment, the shell 11 is connected to the external space, and the cooling end of the semiconductor condenser 12 is located inside the shell 11, which can reduce the temperature of the surrounding air and thus achieve the effect of condensing the air. The heating end of the semiconductor condenser 12 is located outside the shell 11 and will not affect the condensation effect. The guide plate is connected between the cooling end of the semiconductor condenser 12 and the atomizer 13, and can guide the condensed water directly into the atomizer 13.

[0133] In some embodiments, the shell 11 has an air inlet and an air outlet, wherein the air inlet is connected to the outside air, and the air outlet is connected to the inner cavity of the shell 21; the atomization device 10 also includes an airflow driving member 15, which is arranged in the shell 11 and is used to drive the atomization gas in the shell 11 into the inner cavity of the shell 21.

[0134] In the above embodiment, the airflow driving member 15 is arranged in the housing 11, and the airflow driving member 15 can drive the atomized gas generated by the atomizer 13 to be quickly transferred to the inner cavity of the shell 21, thereby improving the preparation efficiency of the plasma activated mist.

[0135] In some embodiments, the airflow driving member 15 includes an air guide fan disposed at the air outlet.

[0136] In the above embodiment, the airflow driving member 15 can directionally guide the atomized gas generated by the atomizer 13 into the inner cavity of the housing 21 by using an air guide fan, thereby improving the preparation efficiency of the plasma activated mist.

[0137] In some embodiments, the atomization device 10 is connected to the activated mist reaction device 20 via an air outlet pipeline 16 , and the air outlet pipeline 16 includes the first air outlet pipeline and the second air outlet pipeline mentioned above.

[0138] In the above embodiment, by setting an air duct between the atomizing device 10 and the activated mist reaction device 20, the atomized gas blown out from the air outlet of the atomizing device 10 can be guided into the activated mist reaction device 20, so as to be conveniently mixed with the plasma in the activated mist reaction device 20 to generate plasma activated mist.

[0139] In some embodiments, Fig.12 As shown, a baffle plate 110 is provided in the housing 11, and the baffle plate 110 divides the inner cavity of the housing 11 into a third chamber 111 and a fourth chamber 112 which are independent of each other; wherein the third chamber 111 is connected to the external environment space, and the fourth chamber 112 is not connected to the external environment space, the semiconductor condenser 12 is arranged in the third chamber 111, and the atomizer 13 is arranged in the fourth chamber 112. Through the above-mentioned baffle design, it can be ensured that the semiconductor condenser 12 can directly obtain air for condensation, and the atomized gas generated by the atomizer 13 can be prevented from diffusing into the external environment space, which affects the preparation efficiency of the plasma activated mist.

[0140] This embodiment is aimed at the air disinfection system of the prior art. The activated mist reaction device used for air sterilization has the problems of low efficiency and complex structure. The atomization device and the electrode structure are very complex and large in size, which are not suitable for product miniaturization design. In addition, the discharge area is relatively small, which leads to the low efficiency of the activated mist. A compact multi-mode switchable air disinfection system is provided, which has a compact structure and can be commercialized, greatly improving the competitiveness of the product.
