Specifically, during the plasma discharge process, high-energy electrons will frequently collide with gas molecules, so that the gas molecules are excited or ionized, and the free radicals such as active oxygen and active hydrogen generated by ionization are used to achieve the purification effect. However, the gas-phase plasma generated by the existing purification device during the ionization process is not stable enough to achieve long-distance transmission, and the purification effect and range are small.

[0006] a first insulating member, mounted in the first installation cavity, extending along the inner wall of the first installation cavity and dividing the first installation cavity into a reaction space and a purification space that are isolated from each other, and the first air outlet and the first communication port are both connected to the purification space;

[0007] The purification component comprises a first electrode and a second electrode, wherein the first electrode is connected to the first communication port, and the second electrode is connected to the reaction space; and an atomizer is connected to the second installation cavity.

[0008] In the technical solution of the embodiment of the present application, the purification device uses the first electrode and the second electrode in the purification component to ionize and generate plasma, and generates water mist through the atomizer and mixes with the plasma to form liquid plasma. Liquid plasma has stronger redox performance and more stable structural performance than gas plasma, can achieve a larger range of propagation, and has a better purification effect. And by further providing a grounded shell and a first insulating member, stable insulation conditions are established for the discharge reaction, and the first electrode and the second electrode to ensure the normal use of the product.

[0009] In one embodiment, an inert medium is further included, and the inert medium is filled in the reaction space.

[0010] In the technical solution of the embodiment of the present application, the inert medium has a low ionization energy, and is easy to ionize to form a stable plasma during the discharge of the second electrode, reducing discharge fluctuations or arc discontinuity, which is conducive to improving the discharge stability of the second electrode. In addition, in a high temperature or high energy ionization environment, the inert medium can prevent the second electrode from undergoing an oxidation reaction, thereby increasing the service life of the product.

[0011] In one embodiment, the inert medium is an inert gas.

[0012] In one embodiment, a second insulating member is further included. A second communication port is formed on the first insulating member. The second insulating member is detachably connected to the first insulating member and is used to open and close the second communication port.

[0014] In one embodiment, the first insulating member is made of a visible insulating material.

[0015] In the technical solution of the embodiment of the present application, the first insulating part is made of visible insulating material, which can facilitate the user to observe the discharge condition of the second electrode and the material condition of the second electrode, thereby facilitating the user to respond promptly to abnormal conditions generated by the second electrode during the discharge process, and to replace and repair the second electrode in time when it is damaged, thereby ensuring the normal operation of the purification device.

At the same time, the second electrode and the high-voltage electrode are connected to generate high-voltage charges, and the high-voltage charges will propagate through the reaction space to the surface attached to the first insulating member 11. In this way, after the mixed gas uniformly mixed with low-voltage charges enters the purification space of the first installation cavity, it can better discharge the high-voltage charges generated by the second electrode on the surface of the first insulating member, thereby ionizing to form a larger number of liquid-phase plasmas, thereby effectively improving the sterilization effect of the liquid-phase plasma.

[0018] In one embodiment, the swirl element is inclined at a preset angle A from an end thereof facing away from the first insulating element toward an end thereof close to the first insulating element, and the preset angle A satisfies the condition: 30°≤A≤80°.

[0019] In the technical solution of the embodiment of the present application, the cyclone component is tilted so that the mixed gas uniformly mixed with low-pressure charges can be concentratedly guided to the surface of the first insulating component by the cyclone component, which is conducive to a more complete discharge reaction between the mixed gas containing low-pressure charges and the high-voltage charges generated by the second electrode, so as to ionize and form a larger number of liquid phase plasmas, thereby effectively improving the sterilization effect of the liquid phase plasma.

[0020] In one embodiment, the first communication port extends along the inner wall of the first installation cavity and surrounds the outer circumference of the first insulating member.

[0021] In the technical solution of the embodiment of the present application, the flow rate of the mixed gas is increased by increasing the area of ​​the first connecting port, and the contact area between the mixed gas and the surface of the first insulating member can be further increased, which is conducive to a more complete discharge reaction between the mixed gas containing low-voltage charges and the high-voltage charges generated by the second electrode, thereby enhancing the sterilization effect of the liquid plasma.

[0022] In one embodiment, the grounded housing further includes a third installation cavity and a second air outlet, the first air outlet is connected between the second installation cavity and the third installation cavity, and the second air outlet is connected to the third installation cavity;

[0040] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0044] With the development of social economy and the gradual improvement of people's living standards, the indoor air quality has attracted increasing attention. At the same time, due to the discovery of the air-borne characteristics of some viruses, a safe and clean indoor air environment has become an urgent need for the general public.

[0045] As a household appliance and similar appliances with a certain removal ability for one or more pollutants such as particulate matter, gaseous pollutants, and microorganisms in the air, the purification device has the characteristics of simple installation, convenient maintenance, and fast purification speed, and thus becomes the first choice for dealing with household air pollution.

[0046] Existing purification devices usually adopt dielectric barrier discharge plasma purification technology to achieve air purification. Specifically, during the plasma discharge process, high-energy electrons will collide frequently with gas molecules, so that the gas molecules are excited or ionized, and the generated active oxygen, active hydrogen and other free radicals are used to achieve the purification effect. However, the gas-phase plasma generated during the ionization process of existing purification devices is not stable enough, cannot be transmitted over a long distance, and the purification effect and range are small.

[0047] Based on the above considerations, in order to solve the above problems, in one or more embodiments of the present application, a purification device 100 is provided, which uses the first electrode 121 and the second electrode 122 in the purification component 12 to ionize and generate plasma, and generates water mist through the atomizing member 16 and mixes it with the plasma to form liquid-phase plasma. Compared with gas-phase plasma, liquid-phase plasma has stronger redox performance and more stable structural performance, can be transmitted over a larger range, and has a better purification effect.

[0048] It should be noted that in this application, gas-phase plasma refers to plasma generated in a gas. Liquid-phase plasma refers to plasma generated in a liquid or on the liquid surface, or plasma generated in combination with a liquid.

[0049] It should also be noted that the water mist generated by the atomizer 16 easily affects the stability of the discharge reaction of the first electrode 121 and the second electrode 122, and in the discharge reaction and high redox environment, it is easy to cause material corrosion to the first electrode 121 and the second electrode 122, seriously reducing the service life of the product. To this end, the present application further uses the grounding shell 10 and the first insulating member 11 to construct stable insulation conditions for the discharge reaction and the first electrode 121 and the second electrode 122 to ensure the normal use of the product.

[0050] Specifically, see Figure 1 and Figure 2 In the present application, the purification device 100 includes a grounded shell 10, a first insulating member 11, a purification assembly 12 and an atomizer 16. The grounded shell 10 includes a first installation cavity 101, a second installation cavity 102, a first connecting port 104, an air inlet 105 and a first air outlet 106. The first connecting port 104 is connected between the first installation cavity 101 and the second installation cavity 102. The first air outlet 106 is connected to the first installation cavity 101, and the air inlet 105 is connected to the second installation cavity 102. The first insulating member 11 is fitted in the first installation cavity 101, and the first insulating member 11 extends along the inner wall of the first installation cavity 101, and divides the first installation cavity 101 into a reaction space 1011 and a purification space 1012 that are separated from each other, and the first air outlet 106 and the first connecting port 104 are both connected to the purification space 1012. The purification component 12 includes a first electrode 121 and a second electrode 122. The first electrode 121 is connected to the first communication port 104, and the second electrode 122 is connected to the reaction space 1011. The atomizer 16 is connected to the second installation cavity 102.

[0051] It is understandable that, during the specific operation of the purification device 100, it is necessary to connect the first electrode 121 to the low-voltage power supply 18, connect the second electrode 122 to the high-voltage power supply 18, connect the grounded shell 10 to the bottom surface, and turn on the atomizer 16 to produce water mist. Thereafter, the outside air to be treated enters the second installation cavity 102 from the air inlet 105 and mixes with the water mist produced by the atomizer 16. Further, the mixed gas formed by the mixture of the air to be treated and the water mist enters the purification space 1012 of the first installation cavity 101 through the first connecting port 104, and the mixed gas will flow through the first electrode 121 in the process of passing through the first connecting port 104, and the first electrode 121 will be attached with a low-voltage charge. At the same time, the second electrode 122 is connected to the high-voltage electrode to generate a high-voltage charge, and the high-voltage charge will propagate through the reaction space 1011 to the surface attached to the first insulating member 11. In this way, after the mixed gas with low-voltage charge enters the purification space 1012 of the first installation cavity 101, it will produce a discharge reaction with the high-voltage charge generated by the second electrode 122 on the surface of the first insulating part 11, thereby ionizing to form liquid plasma. The liquid plasma can achieve a sterilization effect on the mixed gas and can be further discharged to the outside from the first air outlet 106, thereby purifying the external environment.

[0052] In the present application, the first insulating member 11 can isolate the water mist from the second electrode 122, so that the second electrode 122 can be kept away from the high redox environment, thereby preventing the second electrode 122 from being corroded, thereby effectively improving the service life of the product. In addition, the grounded shell 10 can dissipate the excess charge in the purification space 1012, and the grounded shell 10 and the first electrode 121 are at the same potential, so that the abnormal situation of unstable discharge caused by the water mist and the second electrode 122 at the same position can be avoided, so as to ensure the normal operation of the purification device 100.

[0053] That is to say, the purification device 100 provided in the embodiment of the present application uses the first electrode 121 and the second electrode 122 in the purification component 12 to ionize and generate plasma, and generates water mist through the atomizer 16 and mixes with the plasma to form liquid plasma. Liquid plasma has stronger redox performance and more stable structural performance than gaseous plasma, can achieve a larger range of propagation, and has a better purification effect. And by further providing a grounded shell 10 and a first insulating member 11, stable insulation conditions are constructed for the discharge reaction, and the first electrode 121 and the second electrode 122 to ensure the normal use of the product.

[0054] Furthermore, the specific material of the first insulating member 11 is not limited. Figure 1 , Figure 3 and Figure 4The first insulating member 11 is made of a visible insulating material, such as glass, ceramic, polycarbonate, polymethyl methacrylate, etc.

[0055] It is understandable that the visible insulating material refers to a functional material that has both transparent / translucent properties and excellent insulating properties, and can allow visual observation or optical detection while ensuring electrical safety. The present application uses a visible insulating material to make the first insulating member 11, which can facilitate the user to observe the discharge condition of the second electrode 122 and the material condition of the second electrode 122, thereby facilitating the user to respond promptly to abnormal conditions generated by the second electrode 122 during the discharge process, and to replace and repair the second electrode 122 in a timely manner when it is damaged, thereby ensuring the normal operation of the purification device 100.

[0056] In some embodiments, see Figure 1 and Figure 3 The purification device 100 further includes an inert medium 15 , which is filled in the reaction space 1011 .

[0057] It is understandable that the inert medium 15 has a low ionization energy and is easy to ionize to form a stable plasma during the discharge of the second electrode 122, reducing discharge fluctuations or arc discontinuity, which is beneficial to improving the discharge stability of the second electrode 122. In addition, in a high temperature or high energy ionization environment, the inert medium 15 can prevent the second electrode 122 from undergoing an oxidation reaction, thereby increasing the service life of the product.

[0058] In the present application, the specific type of the inert medium 15 is not limited. In some embodiments, the inert medium 15 is an inert gas, such as argon, helium, neon, etc.

[0059] Specifically in the embodiment of the present application, the inert medium 15 is argon gas, and the ionization energy of argon gas is 15.76 eV (electron volt). During the discharge process of the second electrode 122, it is easy to ionize to form a stable plasma, reduce discharge fluctuations or arc discontinuity, and is beneficial to improving the discharge stability of the second electrode 122.

[0060] In some embodiments, see Figure 1 and Figure 3 The purification device 100 further includes a second insulating member 13 . A second communication port 111 is formed on the first insulating member 11 . The second insulating member 13 is detachably connected to the first insulating member 11 and is used to open and close the second communication port 111 .

[0061] It can be understood that by controlling the opening and closing of the second communication port 111 through the second insulating member 13, it is convenient to fill the reaction space 1011 with the inert medium 15 and to assemble the second electrode 122. The second insulating member 13 can seal the second communication port 111 and isolate the water mist from the second electrode 122, so that the second electrode 122 can be kept away from a high redox environment, thereby preventing the second electrode 122 from being corroded, thereby effectively improving the service life of the product.

[0062] In some embodiments, see Figure 1 and Figure 5 The purification device 100 further includes a swirl member 14 , which is configured to guide the airflow to swirl. The swirl member 14 is connected to the first communication port 104 and is located on a side of the first electrode 121 close to the first installation cavity 101 .

[0063] It is understandable that during the specific operation of the purification device 100, the outside air to be treated enters the second installation cavity 102 from the air inlet 105 and mixes with the water mist generated by the atomizer 16. Furthermore, the mixed gas formed by the mixture of the air to be treated and the water mist enters the purification space 1012 of the first installation cavity 101 through the first connecting port 104, and the mixed gas will flow through the swirl member 14 and the first electrode 121 in the process of passing through the first connecting port 104. Among them, the swirl member 14 can guide the mixed gas to rotate and flow, so that the water mist and the air to be treated are fully and evenly mixed, and the low-voltage charge generated by the first electrode 121 can be further mixed with the mixed gas. At the same time, the second electrode 122 is connected to the high-voltage electrode to generate a high-voltage charge, and the high-voltage charge will propagate through the reaction space 1011 to the surface attached to the first insulating member 11. In this way, after the mixed gas evenly mixed with low-voltage charges enters the purification space 1012 of the first installation cavity 101, it can better produce a discharge reaction with the high-voltage charges generated by the second electrode 122 on the surface of the first insulating part 11, thereby ionizing to form a larger number of liquid phase plasmas, thereby effectively improving the sterilization effect of the liquid phase plasma.

[0064] For further information, see Figure 5 and Figure 6 The swirl member 14 is inclined from an end thereof away from the first insulating member 11 toward an end thereof close to the first insulating member 11 .

[0065] It can be understood that by tilting the swirl member 14, the swirl member 14 can be used to guide the mixed gas uniformly mixed with low-pressure charges to the surface of the first insulating member 11, which is conducive to a more complete discharge reaction between the mixed gas containing low-pressure charges and the high-voltage charges generated by the second electrode 122, so as to ionize and form a larger number of liquid phase plasmas, thereby effectively improving the sterilization effect of the liquid phase plasma.

[0066] Specifically in the embodiment of the present application, the swirl member 14 is inclined at a preset angle A from its end away from the first insulating member 11 toward its end close to the first insulating member 11, and the preset angle A satisfies the condition: 30°≤A≤80°.

[0067] It can be understood that when the swirl element 14 is tilted at an angle within the range of 30° to 80°, the swirl element 14 can better evenly mix the mixed gas with low-pressure charges and concentrate it on the surface of the first insulating element 11 to achieve a more sufficient discharge reaction, thereby enabling the purification device 100 to obtain a better sterilization effect.

[0068] It should be noted that the specific value of the preset angle A is obtained through experimental testing, and the parameters, steps, etc. related to the experimental testing of the specific value of the preset angle A are conventional techniques of those skilled in the art and will not be elaborated here.

[0069] In some embodiments, see Figure 1 and Figure 2 The first communication port 104 extends along the inner wall of the first installation cavity 101 and surrounds the outer peripheral side of the first insulating member 11. In this way, by increasing the area of ​​the first communication port 104 to increase the flow rate of the mixed gas, the contact area between the mixed gas and the surface of the first insulating member 11 can be further increased, which is conducive to a more complete discharge reaction between the mixed gas with low-voltage charges and the high-voltage charges generated by the second electrode 122, thereby improving the sterilization effect of the liquid phase plasma.

[0070] In some embodiments, see Figure 1 and Figure 2 The grounded housing 10 further includes a third installation cavity 103 and a second air outlet 107. The first air outlet 106 is connected between the second installation cavity 102 and the third installation cavity 103. The second air outlet 107 is connected to the third installation cavity 103. The purification device 100 further includes a fan 17, which is connected to the third installation cavity 103.

[0071] It is understandable that, during the specific operation of the purification device 100, the fan 17 rotates to generate negative pressure to drive the outside air to be treated from the air inlet 105 into the second installation cavity 102, and mixes with the water mist generated by the atomizer 16. Further, the mixed gas formed by the mixture of the air to be treated and the water mist enters the purification space 1012 of the first installation cavity 101 through the first connecting port 104, and the mixed gas will flow through the swirl member 14 and the first electrode 121 in the process of passing through the first connecting port 104. Among them, the swirl member 14 can guide the mixed gas to rotate and flow, so that the water mist and the air to be treated are fully and evenly mixed, and the low-voltage charge generated by the first electrode 121 can be further mixed with the mixed gas. At the same time, the second electrode 122 is connected to the high-voltage electrode to generate a high-voltage charge, and the high-voltage charge will propagate through the reaction space 1011 to the surface attached to the first insulating member 11. In this way, after the mixed gas uniformly mixed with low-voltage charges enters the purification space 1012 of the first installation cavity 101, it can better discharge the high-voltage charges generated by the second electrode 122 on the surface of the first insulating member 11, thereby ionizing to form a larger number of liquid-phase plasmas. Thereafter, the liquid-phase plasma flows from the first air outlet 106 to the third installation cavity 103 under the action of the fan 17, and is discharged to the outside through the second air outlet 107, thereby purifying the external environment.

The purification device 100 can purify and sterilize the storage space in the refrigerator, thereby improving the freshness preservation effect of the refrigerator.
