[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] With the improvement of living standards, people pay more and more attention to indoor air quality. More and more electrical appliances such as air conditioners and air purifiers are equipped with sterilization modules. In related technologies, a plasma generator is set in an electronic device as a sterilization module. The plasma generator can ionize the air to generate plasma, so that the plasma reacts with pollutants to achieve the purpose of sterilization and disinfection. Since plasma is invisible, it is impossible to intuitively judge the working status of the plasma generator, and when the plasma generator fails, it cannot be discovered immediately.

[0056] In order to solve the above problems, the present invention provides a plasma generating device 100 .

[0057] See also Figures 1 to 5In one embodiment of the present invention, a plasma generating device 100 includes a reaction module 1 and a display structure 2, wherein the reaction module 1 includes a first electrode 11 and a second electrode 12, and the first electrode 11 and the second electrode 12 are arranged at an interval; the display structure 2 includes at least one of a temperature-sensitive color-changing structure 21, an ultraviolet color-developing structure 22, and a rare gas light-emitting structure 23, and the display structure 2 has a first display state and a second display state; wherein the display structure 2 can present the first display state in response to the physical radiation generated when the plasma is generated, and the display structure 2 presents the second display state when the plasma generating device 100 is not working.

[0058] The plasma generating device 100 includes a reaction module 1 for ionizing a fluid to form a plasma, and the reaction module 1 includes a first electrode 11 and a second electrode 12 arranged at intervals; the first electrode 11 and the second electrode 12 can adopt a pin-plate electrode structure, and ionize the air in the form of corona discharge; or a dielectric structure 13 can be arranged between the first electrode 11 and the second electrode 12, and the air can be ionized in the form of dielectric barrier discharge.

[0059] When the plasma generating device 100 is used, an AC voltage is input between the first electrode 11 and the second electrode 12, and acts on the fluid (for example, air, exhaust gas or liquid from certain processes) flowing through the first electrode 11 and the second electrode 12, so that the fluid and the substances in the fluid are charged and become a plasma state, so as to generate plasma, so as to kill VOCs and viruses and bacteria in the fluid, generate water and carbon dioxide, and thus achieve a purification effect.

[0060] In the embodiment of the present application, a display structure 2 is further provided in the plasma generating device 100, and the display structure 2 is located in the plasma generating area. The display structure 2 can be set as a temperature-sensitive color-changing structure 21. When the plasma generating device 100 is in a working state and ionizes air to generate plasma, heat is also released. The heat is transferred to the temperature-sensitive color-changing structure 21, which will change the color of the temperature-sensitive color-changing structure 21, and the display structure 2 presents a first display state; when the plasma generating device 100 is not applied with voltage or fails, the plasma generating device 100 does not work, no plasma is generated, the temperature-sensitive color-changing structure 21 maintains the original color of the natural state, and the display structure 2 presents a second display state.

[0061] The display structure 2 can also be set as an ultraviolet color development structure 22. When the plasma generating device 100 is in operation, it will also emit lavender light and ultraviolet light, but the lavender light is relatively weak and difficult to be directly seen. The ultraviolet color development structure 22 can change color in response to the ultraviolet light generated during the plasma generation process, so that the display structure 2 presents a first display state; when the plasma generating device 100 is not working, the ultraviolet color development structure 22 maintains the original color, and the display structure 2 presents a second display state.

[0062] The display structure 2 can also be set as a rare gas light-emitting structure 23. The display structure 2 is formed with a filling cavity, and rare gas is filled in the filling cavity, such as at least one of helium, neon, argon, krypton, xenon and radon. When the plasma module is working, there will be a strong alternating electric field in the working area. The rare gas light-emitting structure 23 is located in the alternating electric field. In the alternating electric field, charged particles are accelerated to obtain a large amount of energy. The charged particles collide with gas molecules, which can cause rare gases such as helium, neon, argon, krypton, and xenon to ionize and emit light. In addition, the temperature-sensitive color-changing structure 21, the ultraviolet color-developing structure 22, and the rare gas light-emitting structure 23 are used as the display structure 2, and the heat, ultraviolet light, and electromagnetic field generated by the plasma generator 100 in the working state are used to change the display state. Physical radiation, such as, for example, the heat, ultraviolet light, and electromagnetic field generated by the plasma generator 100 in the working state can be used to intuitively indicate the working state of the plasma generator 100, and there is no need to input additional energy, reduce energy consumption, and there is no need to consider the access method of additional energy, simplifying the structure of the plasma generator 100.

[0063] It should be noted that in the embodiment of the present application, the display structure 2 may include a temperature-sensitive color-changing structure 21, or two or more temperature-sensitive color-changing structures 21 may be provided; similarly, the display structure 2 may be provided with a UV color-developing structure 22 or a rare gas light-emitting structure 23, or two or more UV color-developing structures 22 may be provided, and two or more rare gas light-emitting structures 23 may be provided. In addition, the display structure 2 may be provided with two or three of the temperature-sensitive color-changing structure 21, the UV color-developing structure 22, and the rare gas light-emitting structure 23 at the same time, which is not specifically limited here.

[0064] That is, the technical solution of the present invention is to set at least one of the temperature-sensitive color-changing structure 21, the ultraviolet color-developing structure 22 and the rare gas light-emitting structure 23 as the display structure 2 in the plasma generator 100, so that the display structure 2 can present different display states according to the change of at least one physical property in the environment. In the process of the plasma generator 100 ionizing air to generate plasma when working normally, physical radiation such as heat, ultraviolet rays, and electromagnetic waves will be generated at the same time. At this time, the display structure 2 can be changed in color or emit light to present a first display state. When the plasma generator 100 is not working or fails, the display structure 2 displays the original color or does not emit light to present a second display state; such a setting makes the working state of the plasma generator 100 visualized, and the working state of the plasma generator 100 can be intuitively judged through the display state of the display structure 2.

[0065] See also Figure 3 , Figure 7 as well as Fig.11In some embodiments, a temperature-sensitive color-changing layer is provided on the surface of at least one of the first electrode 11 and the second electrode 12 , and the temperature-sensitive color-changing layer serves as the temperature-sensitive color-changing structure 21 .

[0066] In this embodiment, a temperature-sensitive color-changing layer can be provided on at least part of the surface of the first electrode 11 as the temperature-sensitive color-changing structure 21, or a temperature-sensitive color-changing layer can be provided on at least part of the surface of the second electrode 12 as the temperature-sensitive color-changing structure 21; of course, a temperature-sensitive color-changing layer can also be provided on the surfaces of both the first electrode 11 and the second electrode 12. It can be understood that when the plasma generating device 100 is working, an alternating current is applied to the first electrode 11 and the second electrode 12 to ionize the air; the temperature-sensitive color-changing layer is provided on at least one of the first electrode 11 and the second electrode 12, so that the temperature-sensitive color-changing structure 21 can respond faster and more accurately to the temperature change when the plasma is generated, thereby improving the sensitivity. At the same time, the temperature-sensitive color-changing layer is provided on the surfaces of the first electrode 11 and the second electrode 12, so that the working state of the plasma generating device 100 can be more accurately judged by the display state of the temperature-sensitive color-changing structure 21 at different positions.

[0067] Moreover, this arrangement, using the first electrode 11 and the second electrode 12 to carry the temperature-sensitive color-changing structure 21, eliminates the need to set up additional structural parts in the plasma generating device 100, reduces the number of components of the plasma generating device, simplifies the structure of the plasma generating device 100, and is also conducive to the miniaturization of the plasma generating device 100.

[0068] See also Figure 4 , Figure 8 as well as Fig.12 In some embodiments, a surface of at least one of the first electrode 11 and the second electrode 12 is provided with an ultraviolet color development layer, and the ultraviolet color development layer serves as the ultraviolet color development structure 22 .

[0069] In this embodiment, an ultraviolet color developing layer can be provided on at least part of the surface of the first electrode 11 as the ultraviolet color developing structure 22, or an ultraviolet color developing layer can be provided on at least part of the surface of the second electrode 12 as the ultraviolet color developing structure 22; of course, an ultraviolet color developing layer can also be provided on the surface of both the first electrode 11 and the second electrode 12. It can be understood that when the plasma generating device 100 is working, an alternating current is applied to the first electrode 11 and the second electrode 12 to ionize the air; the ultraviolet color developing layer is provided on at least one of the first electrode 11 and the second electrode 12, so that the ultraviolet color developing structure 22 can respond faster and more accurately to the ultraviolet light generated when the plasma is generated, thereby improving the sensitivity. At the same time, the ultraviolet color developing layer is provided on the surface of the first electrode 11 and the second electrode 12, so that the working state of the plasma generating device 100 can be more accurately judged by the display state of the ultraviolet color developing structure 22 at different positions.

[0070] Moreover, this arrangement, using the first electrode 11 and the second electrode 12 to carry the ultraviolet color development structure 22, eliminates the need to provide additional structural parts in the plasma generating device 100, reduces the number of components of the plasma generating device, simplifies the structure of the plasma generating device 100, and is also conducive to the miniaturization of the plasma generating device 100.

[0071] In some embodiments, a temperature-sensitive color-changing layer may be disposed on the surface of one of the first electrode 11 and the second electrode 12, and an ultraviolet color-developing layer may be disposed on the other of the first electrode 11 and the second electrode 12, so that the working state of the plasma generating device 100 may be more accurately judged according to the display states of different display structures 2.

[0072] See also Figure 5 , Fig. 9 as well as Fig.13 In some embodiments, the reaction module 1 and the display structure 2 are separately provided.

[0073] In this embodiment, the display structure 2 may be disposed on the housing 3 for mounting the reaction module 1 , or a bracket or other bearing structure may be separately disposed for fixing the display structure 2 .

[0074] See also Figures 2 to 9 In some embodiments, the reaction module 1 further includes a dielectric structure 13 , and the first electrode 11 and the second electrode 12 are respectively located on two sides of the dielectric structure 13 that are arranged back to back.

[0075] In this embodiment, the reaction module 1 further includes a dielectric structure 13, which is arranged between the first electrode 11 and the second electrode 12. The dielectric structure 13 can be made of ceramic, quartz or other insulating materials, and can be a planar dielectric structure, or the dielectric structure 13 can be formed into a tubular structure or a box structure, which is used to cover at least part of the second electrode 12 or the first electrode 11; the first electrode 11 and the second electrode 12 are respectively arranged on the two sides of the dielectric structure 13 that are arranged back to back, and are separated from each other by the dielectric structure 13; for example, the first electrode 11 and the second electrode 12 can be respectively arranged on the two sides of the planar dielectric structure, or the first electrode 11 and the second electrode 12 can be respectively arranged on the inner side and the outer side of the tubular dielectric structure. When the first electrode 11 and the second electrode 12 are energized, a dielectric barrier discharge can be formed on the surface of the dielectric structure 13, and act on the fluid (for example, air, exhaust gas or liquid from certain processes) flowing through the first electrode 11 and the second electrode 12, so that the fluid and the substances in the fluid are charged and become plasma state, so as to generate plasma, so as to kill VOC and viruses and bacteria in the fluid, and generate water and carbon dioxide, so as to achieve purification.

[0076] See also Figures 2 to 4In some embodiments, the display structure 2 is disposed on the dielectric structure 13; wherein the display structure 2 may be fixed on the dielectric structure 13, for example, at least one of a temperature-sensitive color-changing layer and an ultraviolet color-developing layer is disposed on the surface of the dielectric structure 13, or the dielectric structure 13 may be used to fix the rare gas light-emitting structure 23; the dielectric structure 13 may also be reused as the rare gas light-emitting structure 23 as in the following embodiments, which is not limited here.

[0077] See also Figure 5 and Fig. 9 In some embodiments, the dielectric structure 13 is separately provided from the display structure 2. The display structure 2 may be provided on the first electrode 11, the second electrode 12 or the housing 3 in the following embodiment, or a bearing structure for providing the display structure 2 may be separately provided from the dielectric structure 13.

[0078] See also Figures 6 to 8 In some embodiments, at least a portion of the surface of the dielectric structure 13 is provided with at least one of a temperature-sensitive color-changing layer and an ultraviolet color-developing layer to form a display structure 3 on the surface of the dielectric structure 13 .

[0079] In this embodiment, a temperature-sensitive color-changing layer may be provided on at least part of the surface of the dielectric structure 13 as the temperature-sensitive color-changing structure 21, and an ultraviolet color-developing layer may be provided on at least part of the surface of the dielectric structure 13 as the ultraviolet color-developing structure 22; in addition, a temperature-sensitive color-changing layer may be provided on part of the surface of the dielectric structure 13, and an ultraviolet color-developing layer may be provided on another part of the surface. In this way, at least one of the temperature-sensitive color-changing structure 21 and the ultraviolet color-developing structure 22 is provided as a coating on the surface of the dielectric structure 13. On the one hand, it is not necessary to provide an additional structural member in the plasma generator 100 to fix the display structure 2, and the volume of the combined structure of the dielectric structure 13 and the display structure 2 may be reduced, which is conducive to the miniaturization of the plasma generator 100.

[0080] In some embodiments, the material components of the dielectric structure 13 include at least one of a temperature-sensitive color-changing material and an ultraviolet color-developing material, so that the dielectric structure 13 forms a display structure 2 .

[0081] This arrangement is to reuse the dielectric structure 13 itself as the display structure 2. The dielectric structure 13 has a first display state and a second display state. The dielectric structure 13 can change color under the action of heat or ultraviolet light. When the plasma generating device 100 is working normally, the dielectric structure 13 can change color in response to at least one physical radiation of the generated heat and ultraviolet light to present the first display state. When the plasma generating device 100 is not working, the dielectric structure 13 displays the original color to present the second display state. By using the dielectric structure 13 as the display structure 2, the working state of the plasma generating device 100 can be reflected faster and more accurately, and the number of components of the plasma generating device 100 is reduced. There is no need to install and set up an additional display structure 2, making the disassembly and assembly of the plasma generating device 100 more convenient.

[0082] In some embodiments, at least a portion of the dielectric structure 13 is configured as a light-transmitting structure, a closed filling cavity is formed in the dielectric structure 13 , and the filling cavity is filled with a rare gas, so that the dielectric structure 13 serves as a rare gas light-emitting structure 23 .

[0083] In this embodiment, the dielectric structure 13 has a hollow filling cavity, in which a rare gas is filled, and at least part of the dielectric structure 13 is transparent, for example, the dielectric structure 13 is entirely made of quartz or transparent plastic material, and part of the cavity wall of the filling cavity can also be made of transparent material; thus, the dielectric structure 13 can be reused as a rare gas light-emitting structure 23. This arrangement does not require the provision of an additional bulb as a display structure 3, thereby reducing the use of components in the plasma generator 100; when the plasma generator 100 is working normally to generate an alternating electric field, the rare gas light-emitting structure 23 formed by the dielectric structure 13 can be at a position with a higher field strength in the alternating electric field, thereby better stimulating the rare gas to emit light, improving the light brightness, and allowing the user to better observe and judge the working state of the plasma generator 100.

[0084] See also Figures 2 to 5 In some embodiments, at least a portion of the first electrode 11 is configured as a strip structure, the dielectric structure 13 is coated on the outside of at least a portion of the strip structure, and the second electrode 12 is disposed on the outside of the dielectric structure 13 .

[0085] In this embodiment, at least part of the first electrode 11 can be set as a strip structure, such as a linear electrode or a rectangular electrode, and the dielectric structure 13 is coated on the outside of the part of the first electrode 11 set as a strip structure. The dielectric structure 13 can be attached to the outer surface of the first electrode 11, or can be set at a distance from the first electrode 11, such as a round tube, a square tube or other polygonal tube set around the strip structure; the second electrode 12 is set on the outside of the dielectric structure 13; in this setting method, the first electrode 11 and the second electrode 12 are respectively set on the inner and outer sides of the dielectric structure 13, so that the first electrode 11 and the second electrode 12 are separated by the dielectric structure 13, which can make the structure of the plasma generating device 100 more compact.

[0086] In this embodiment, the display structure 2 can be arranged on the dielectric structure 13, for example, at least one of a temperature-sensitive color-changing layer and an ultraviolet color-developing layer can be arranged on the outer surface of the dielectric structure 13, and at least one of a temperature-sensitive color-changing material and an ultraviolet color-developing material can be mixed into the raw materials of the dielectric structure 13, so that the dielectric structure 13 itself can change color in response to temperature changes and ultraviolet light; a filling cavity filled with a rare gas can also be arranged in the dielectric structure 13, and at least part of the outer surface of the dielectric structure 13 can be transparent, so that the dielectric structure 13 serves as a rare gas light-emitting structure 23. In addition, at least one of a temperature-sensitive color-changing layer and an ultraviolet color-developing layer can also be arranged on the surface of the first electrode 11 that is not wrapped by the dielectric structure 13, and at least one of a temperature-sensitive color-changing layer and an ultraviolet color-developing layer can also be arranged on the surface of the second electrode 12. Of course, the display structure 2 can be separately arranged from the dielectric structure 13, the first electrode 11 and the second electrode 12, and the display structure 2 can be arranged adjacent to the second electrode 12, so that when the plasma generating device 100 works normally, the display structure 2 can be located in the physical radiation field generated when the plasma is generated, ensuring that the display structure 2 can respond to at least one physical radiation of heat, ultraviolet light and electromagnetic field generated when the plasma is generated and present the first display state.

[0087] Optionally, the dielectric structure 13 can be made of a rigid material such as quartz, ceramic, etc., to improve the structural stability of the dielectric structure 13 and the plasma generator 100. In some embodiments, the first electrode 11, the dielectric structure 13, and the second electrode 12 can also be set as a bendable and deformable structure, for example, the first electrode 11 and the second electrode 12 are made of a flexible and completely metal wire or metal strip; the dielectric structure 13 can be made of resin, plastic, silicone rubber, PVC (polyvinyl chloride) and other materials to form an insulating and flexible insulating outer skin, or a number of quartz and ceramic particles can be attached to a flexible carrier. In this way, the plasma generator 100 can be bent and coiled according to the different use environments and installation spaces to suit different use scenarios.

[0088] See also Figures 2 to 5 In some embodiments, the second electrode 12 is wound around the outside of the dielectric structure 13. The second electrode 12 can be set as a spiral electrode extending spirally along the outer surface of the dielectric structure 13, or can be set as a mesh electrode or other structure. This setting can increase the discharge area between the first electrode 11 and the second electrode 12, so that more plasma is generated between the first electrode 11 and the second electrode 12.

[0090] In this embodiment, at least part of the dielectric structure 13 is set as a planar dielectric structure, for example, the dielectric structure 13 can be set as a plate structure as a whole, or the dielectric structure 13 can be set as a cover structure with a planar sidewall; the planar dielectric structure is arranged between the first electrode 11 and the second electrode 12, and when a voltage is applied to the first electrode 11 and the second electrode 12, a surface dielectric barrier discharge can be formed, and plasma can be formed on the surface of the dielectric structure 13. Among them, the first electrode 11 and the second electrode 12 can be both linear electrodes, or both planar electrodes, or one of the first electrode 11 and the second electrode 12 can be set as a flat strip electrode, which is not limited here.

The plate electrode is disposed opposite to the planar dielectric structure, and a larger reaction area is provided on one side of the second electrode 12, so that a larger area of ​​air can be ionized to generate plasma. The second electrode 12 is configured as a strip electrode, such as a linear electrode or a rectangular electrode, so that the generation area and diffusion area of ​​the plasma can be controlled, which is convenient for utilizing the plasma.

[0093] In some embodiments, the shapes of the first electrode 11 and the second electrode 12 can be different, for example, the first electrode 11 is set as a strip electrode and the second electrode 12 is set as a plate electrode; or, when the first electrode 11 and the second electrode 12 are both strip electrodes, the end of the second electrode 12 is blunter than the end of the first electrode 11, both of which can make the field strength on the first electrode 11 side higher than the field strength on the second electrode 12 side, so that more plasma is concentrated on the side of the first electrode 11 with higher field strength.

[0094] See also Figures 10 to 13 In some embodiments, one of the first electrode 11 and the second electrode 12 has a tip facing the other electrode, and the other of the first electrode 11 and the second electrode 12 is a plate electrode; or, the first electrode 11 and the second electrode 12 have tips arranged opposite to each other.

The first electrode 11 and the second electrode 12 are arranged relative to each other, so that at least one of the first electrode 11 and the second electrode 12 is provided with a tip, and the first electrode 11 is arranged as a plate electrode and the second electrode 12 is arranged as a needle electrode; or the first electrode 11 is arranged as a needle electrode and the second electrode 12 is arranged as a plate electrode, and the first electrode 11 and the second electrode 12 are both provided with a tip facing the other electrode.

This arrangement allows the display structure 2 to be adjacent to an electrode with a higher field strength, thereby better and more sensitively responding to heat, ultraviolet light or an alternating electric field to change color or emit light.

[0098] See also Figure 1 In some embodiments, the plasma generating device 100 further includes a shell 3 , the shell 3 is formed with an installation cavity 31 , the shell 3 has an opening connected to the installation cavity 31 , and the reaction module 1 is disposed in the installation cavity 31 .

[0099] In this embodiment, a shell 3 is provided in the plasma generator 100, and the reaction module 1 is accommodated in the installation cavity 31 of the shell 3. The plasma generated by the plasma generator 100 when working can diffuse outward from the opening of the shell 3, which is convenient for controlling the diffusion position of the plasma. In addition, the dielectric structure 13, the first electrode 11 and the second electrode 12 are integrated into an integral structure, which can keep the relative positions of the structures of the reaction module 1 stable, and improve the performance stability of the plasma generator 100; and when the plasma generator 100 is applied to electrical equipment, the plasma generator 100 can be disassembled as a whole, without the need to separately disassemble and assemble the various components of the plasma generator 100 in the electrical equipment, thereby improving the convenience of use.

[0100] In this embodiment, the display structure 2 can be set on at least one of the dielectric structure 13, the first electrode 11 and the second electrode 12 as in the above embodiment, or it can be set on the shell 3, or for example, the display structure 2 can be fixed on the shell 3, or the shell 3 can be reused as the display structure 2; in addition, the display structure 2 can also be set on the outside of the shell 3 and separated from the shell 3, which is not limited here.

[0101] See also Figure 1 In some embodiments, the display structure 2 and the shell 3 are separately provided; or, the display structure 2 is provided in the shell 3.

[0102] In this embodiment, the display structure 2 can be separately provided from the shell 3, for example, the display structure 2 is provided on at least one of the dielectric structure 13, the first electrode 11 and the second electrode 12 located on the inner side of the shell 3; the display structure 2 can also be provided on the outer side of the shell 3, for example, a support structure such as a bracket is provided on the outer side of the shell 3 to fix the display structure 2. When the plasma generating device 100 is applied to equipment such as air conditioners and air purifiers, the display structure 2 can also be fixed on the equipment.

[0103] In addition, the display structure 2 can also be set on the shell 3, for example, the display structure 2 can be set on the surface of the shell 3, and the shell 3 can also be reused as at least one of the temperature-sensitive color-changing structure 21, the ultraviolet color-developing structure 22 and the rare gas light-emitting structure 23. The specific implementation method refers to the following embodiment and is not repeated here.

[0104] See also Figure 1In some embodiments, the display structure 2 is disposed around the opening of the housing 3. In this arrangement, the display structure 2 is disposed near the plasma generating area, so as to more sensitively respond to the physical radiation such as heat, ultraviolet light, and electromagnetic field generated when the plasma is generated and switch the display state, and the display structure 2 is exposed outside the housing 3, so that the user can observe the display state of the display structure 2 to judge the working state of the plasma generating device 100.

[0105] See also Figure 1 In some embodiments, the display structure 2 is disposed on the outer surface of the housing 3. For example, at least one of the rare gas light-emitting structure 23, the temperature-sensitive color-changing structure 21, and the ultraviolet color-developing structure 22 can be fixed on the outer surface of the housing 3. This arrangement makes it easy for the user to observe the display state of the display structure 2 to determine the working state of the plasma generating device 100. In addition, by using the housing 3 to carry the display structure 2, it is not necessary to set an additional structural member in the plasma generating device 100 to fix the color-developing device, thereby reducing the number of components of the plasma generating device, simplifying the structure of the plasma generating device 100, and facilitating the miniaturization of the plasma generating device 100.

[0106] In some embodiments, at least one of a temperature-sensitive color-changing layer and an ultraviolet color-developing layer is disposed on the surface of the shell 3 to form a display structure 2 on the surface of the shell 3 .

[0107] In this embodiment, a temperature-sensitive color-changing layer can be provided on at least part of the surface of the housing 3 as the temperature-sensitive color-changing structure 21, and an ultraviolet color-developing layer can be provided on at least part of the surface of the housing 3 as the ultraviolet color-developing structure 22; in addition, a temperature-sensitive color-changing layer can be provided on part of the surface of the housing 3, and an ultraviolet color-developing layer can be provided on another part of the surface. In this way, at least one of the temperature-sensitive color-changing structure 21 and the ultraviolet color-developing structure 22 is provided as a coating on the surface of the housing 3. On the one hand, it is not necessary to provide an additional structural member in the plasma generator 100 to fix the display structure 2, and the volume of the combined structure of the housing 3 and the display structure 2 can be reduced, which is conducive to the miniaturization of the plasma generator 100.

[0108] In some embodiments, the material components of the shell 3 include at least one of a temperature-sensitive color-changing material and an ultraviolet color-developing material, so that the shell 3 serves as a display structure 2 .

[0109] Among them, a thermochromic material can be added to the material components for preparing the shell 3, so that the shell 3 itself has the ability to change color according to temperature changes; an ultraviolet color-developing material can also be added to the material components for preparing the shell 3, so that the shell 3 itself has the ability to change color in response to ultraviolet light; in addition, a thermochromic material and an ultraviolet color-developing material can be added to the material components for preparing the shell 3 at the same time, and the material components at different positions of the shell 3 can also include a thermochromic material and an ultraviolet color-developing material respectively. This setting method is to reuse the shell 3 as the display structure 2, and the working state of the plasma generator 100 can be intuitively judged by the change of the display state of the shell 3. The structure of the plasma generator 100 is relatively simple and easy to manufacture.

[0110] In some embodiments, at least a portion of the shell wall of the shell 3 is made of a light-transmitting material, a filling cavity is formed in the shell wall, and the filling cavity is filled with a rare gas, so that the shell 3 serves as a rare gas light-emitting structure 23 .

[0111] In this embodiment, at least part of the shell wall of the shell 3 has a hollow filling cavity, and at least one rare gas among helium, neon, argon, krypton, xenon and radon is filled in the filling cavity, and the shell wall enclosing the filling cavity is made transparent, for example, the shell 3 is set as a quartz or light-transmitting plastic material as a whole, and part of the cavity wall of the filling cavity can also be set as a light-transmitting material; thereby, the shell 3 can be reused as a rare gas light-emitting structure 23. This setting method does not require the provision of an additional bulb as a display structure 3, reducing the use of parts in the plasma generator 100; when the plasma generator 100 works normally to generate an alternating electric field, the rare gas in the filling cavity emits light under the action of the electric field and is transmitted from the shell 3, which is convenient for users to observe and judge the working state of the plasma generator 100.

The electrical device may be, but is not limited to, an air conditioner, an air purifier, etc. The specific structure of the plasma generator 100 refers to the above embodiments.
