[0053] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0055] With the improvement of living standards, indoor air quality is receiving increasing attention, and more and more electrical appliances, such as air conditioners and air purifiers, are equipped with sterilization modules. In related technologies, plasma generators are incorporated into electronic devices as sterilization modules. These generators ionize the air to produce plasma, which then reacts with pollutants to achieve sterilization and disinfection. However, because plasma is invisible, the working status of the plasma generator cannot be directly determined, and malfunctions in the plasma generator cannot be detected immediately.

[0056] To address the aforementioned problems, the present invention proposes a plasma generating device 100.

[0057] Please see Figures 1 to 5In one embodiment of the present invention, the plasma generating device 100 includes a reaction module 1 and a display structure 2. The reaction module 1 includes a first electrode 11 and a second electrode 12, which are spaced apart. The display structure 2 includes at least one of a thermosensitive color-changing structure 21, an ultraviolet color-developing structure 22, and a rare gas light-emitting structure 23. The display structure 2 has a first display state and a second display state. The display structure 2 can present the first display state in response to the physical radiation generated when plasma is generated, and present 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 fluid to form plasma. 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 needle plate electrode structure and ionize air by corona discharge. Alternatively, a dielectric structure 13 can be provided between the first electrode 11 and the second electrode 12 to ionize air by dielectric barrier discharge.

[0059] When the plasma generator 100 is used, an AC voltage is input between the first electrode 11 and the second electrode 12 and applied to the fluid (e.g., air, exhaust gas or liquid from certain processes) flowing through the first electrode 11 and the second electrode 12, causing the fluid and the substances in the fluid to become charged and become plasma, thereby generating plasma to kill VOCs and viruses and bacteria in the fluid and generate water and carbon dioxide, thereby achieving a purification effect.

[0060] In this embodiment, a display structure 2 is also 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 configured as a thermosensitive color-changing structure 21. When the plasma generating device 100 is in working state and generates plasma by ionizing air, it will also release heat. The heat is transferred to the thermosensitive color-changing structure 21, which will cause the thermosensitive color-changing structure 21 to change color, and the display structure 2 will present a first display state. When the plasma generating device 100 is not subjected to voltage or malfunctions, the plasma generating device 100 does not work and no plasma is generated. The thermosensitive color-changing structure 21 maintains its original color in its natural state, and the display structure 2 presents a second display state.

[0061] The display structure 2 can also be configured as an ultraviolet color-changing structure 22. When the plasma generator 100 is in operation, it also emits pale purple light and ultraviolet light. The pale purple light is relatively weak and difficult to see directly. The ultraviolet color-changing structure 22 can change color in response to the ultraviolet light generated during plasma generation, so that the display structure 2 presents a first display state; when the plasma generator 100 is not in operation, the ultraviolet color-changing structure 22 maintains its original color, and the display structure 2 presents a second display state.

[0062] The display structure 2 can also be configured as a rare gas luminescent structure 23. The display structure 2 has a filling cavity filled with a rare gas, such as at least one of helium, neon, argon, krypton, xenon, and radon. When the plasma module is working, a strong alternating electric field exists in the working area. The rare gas luminescent structure 23 is located within this alternating electric field. In this field, charged particles accelerate and gain a large amount of energy. Collisions between the charged particles and gas molecules ionize and emit light from rare gases such as helium, neon, argon, krypton, and xenon. Furthermore, by employing a thermosensitive color-changing structure 21, an ultraviolet color-developing structure 22, and a rare gas luminescent structure 23 as the display structure 2, the display state changes due to the heat, ultraviolet light, and electromagnetic field generated by the plasma generator 100 during operation. This allows for a direct indication of the plasma generator 100's operating status without requiring additional energy input, reducing energy consumption and simplifying the structure of the plasma generator 100 by eliminating the need to consider additional energy input methods.

[0063] It should be noted that, in this embodiment, the display structure 2 may include one thermochromic structure 21, or two or more thermochromic structures 21; similarly, the display structure 2 may include one ultraviolet color-changing structure 22 or one rare gas luminescent structure 23, or two or more ultraviolet color-changing structures 22 and two or more rare gas luminescent structures 23. Furthermore, the display structure 2 may simultaneously include two or three of the thermochromic structure 21, ultraviolet color-changing structure 22, and rare gas luminescent structure 23; no specific limitation is made here.

[0064] In other words, the technical solution of the present invention, by setting at least one of a thermosensitive color-changing structure 21, an ultraviolet color-developing structure 22, and a rare gas light-emitting structure 23 as a display structure 2 in the plasma generator 100, allows the display structure 2 to present different display states according to changes in at least one physical characteristic of the environment. During the normal operation of the plasma generator 100 in ionizing air to generate plasma, physical radiation such as heat, ultraviolet rays, and electromagnetic waves is simultaneously generated. At this time, the display structure 2 can change color or emit light to present a first display state. When the plasma generator 100 is not working or malfunctions, the display structure 2 displays its original color or does not emit light to present a second display state. This arrangement makes the working state of the plasma generator 100 visible, and the working state of the plasma generator 100 can be intuitively judged by the display state of the display structure 2.

[0065] Please see Figure 3 , Figure 7 as well as Figure 11In some embodiments, at least one of the first electrode 11 and the second electrode 12 has a thermochromic layer on its surface, which serves as a thermochromic structure 21.

[0066] In this embodiment, a thermochromic layer can be provided on at least a portion of the surface of the first electrode 11 as a thermochromic structure 21, or a thermochromic layer can be provided on at least a portion of the surface of the second electrode 12 as a thermochromic structure 21; of course, thermochromic layers can also be provided on the surfaces of both the first electrode 11 and the second electrode 12. It is understood that when the plasma generator 100 is operating, alternating current is applied to the first electrode 11 and the second electrode 12 to ionize the air; by providing a thermochromic layer on at least one of the first electrode 11 and the second electrode 12, the thermochromic structure 21 can respond more quickly and accurately to temperature changes during plasma generation, thus improving sensitivity. Simultaneously, by providing thermochromic layers on the surfaces of the first electrode 11 and the second electrode 12, the operating state of the plasma generator 100 can be more accurately determined by observing the display status of the thermochromic structure 21 at different locations.

[0067] Furthermore, this configuration, which utilizes the first electrode 11 and the second electrode 12 to support the thermosensitive color-changing structure 21, eliminates the need for additional structural components in the plasma generator 100, reduces the number of components in the plasma generator, simplifies the structure of the plasma generator 100, and also facilitates the miniaturization of the plasma generator 100.

[0068] Please see Figure 4 , Figure 8 as well as Figure 12 In some embodiments, at least one of the first electrode 11 and the second electrode 12 has an ultraviolet color-developing layer on its surface, which serves as the ultraviolet color-developing structure 22.

[0069] In this embodiment, an ultraviolet (UV) color-developing layer can be disposed on at least a portion of the surface of the first electrode 11 as the UV color-developing structure 22, or an UV color-developing layer can be disposed on at least a portion of the surface of the second electrode 12 as the UV color-developing structure 22; of course, UV color-developing layers can also be disposed on the surfaces of both the first electrode 11 and the second electrode 12. It is understood that when the plasma generator 100 is operating, applying alternating current to the first electrode 11 and the second electrode 12 ionizes the air; disposing the UV color-developing layer on at least one of the first electrode 11 and the second electrode 12 allows the UV color-developing structure 22 to respond more quickly and accurately to the UV light generated during plasma generation, thus improving sensitivity. Simultaneously, disposing the UV color-developing layer on the surfaces of the first electrode 11 and the second electrode 12 allows for a more accurate determination of the operating state of the plasma generator 100 by observing the display status of the UV color-developing structures 22 at different locations.

[0070] Furthermore, this configuration, which utilizes the first electrode 11 and the second electrode 12 to support the ultraviolet color development structure 22, eliminates the need for additional structural components in the plasma generator 100, reduces the number of components in the plasma generator, simplifies the structure of the plasma generator 100, and also facilitates the miniaturization of the plasma generator 100.

[0071] In some embodiments, a thermosensitive color-changing layer can be provided on the surface of one of the first electrode 11 and the second electrode 12, and an ultraviolet color-developing layer can be provided on the other of the first electrode 11 and the second electrode 12, so that the working state of the plasma generator 100 can be more accurately determined according to the display state of different display structures 2.

[0072] Please see Figure 5 , Figure 9 as well as Figure 13 In some implementations, the reaction module 1 and the display structure 2 are set separately.

[0073] In this embodiment, the display structure 2 can be mounted on the housing 3 used to install the reaction module 1, or a separate bracket or other supporting structure can be used to fix the display structure 2.

[0074] Please see Figures 2 to 9 In some embodiments, the reaction module 1 further includes a dielectric structure 13, with the first electrode 11 and the second electrode 12 located on opposite sides of the dielectric structure 13.

[0075] In this embodiment, the reaction module 1 further includes a dielectric structure 13, which is disposed between the first electrode 11 and the second electrode 12. The dielectric structure 13 can be made of ceramic, quartz, or other insulating materials. It can be a planar dielectric structure, or it can be formed into a tubular or box-like structure 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 disposed on opposite sides of the dielectric structure 13 and separated from each other by the dielectric structure 13. For example, the first electrode 11 and the second electrode 12 can be disposed on opposite sides of the planar dielectric structure, or the first electrode 11 and the second electrode 12 can be disposed on the inner and outer sides 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 (e.g., air, exhaust gas or liquid from certain processes) flowing through the first electrode 11 and the second electrode 12, causing the fluid and substances in the fluid to become charged and become plasma, thereby generating plasma to kill VOCs and viruses and bacteria in the fluid and generate water and carbon dioxide, thereby achieving a purification effect.

[0076] Please see 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 thermosensitive color-changing layer and an ultraviolet color-developing layer may be disposed on the surface of the dielectric structure 13, or the rare gas light-emitting structure 23 may be fixed using the dielectric structure 13; the dielectric structure 13 may also be reused as the rare gas light-emitting structure 23 in the following embodiments, which is not limited here.

[0077] Please see Figure 5 and Figure 9 In some embodiments, the dielectric structure 13 and the display structure 2 are separately configured. The display structure 2 can be disposed on the first electrode 11, the second electrode 12, or the housing 3 in the following embodiments, or the carrier structure for disposing of the display structure 2 can be separately configured from the dielectric structure 13.

[0078] Please see 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 thermochromic 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 thermochromic layer can be formed on at least a portion of the surface of the dielectric structure 13 as a thermochromic structure 21, or an ultraviolet color-developing layer can be formed on at least a portion of the surface of the dielectric structure 13 as an ultraviolet color-developing structure 22; alternatively, a thermochromic layer can be formed on a portion of the surface of the dielectric structure 13, and an ultraviolet color-developing layer can be formed on another portion of the surface. This configuration, where at least one of the thermochromic structure 21 and the ultraviolet color-developing structure 22 is a coating on the surface of the dielectric structure 13, eliminates the need for additional structural components to fix the display structure 2 in the plasma generator 100, and also reduces the volume of the combined structure of the dielectric structure 13 and the display structure 2, thus facilitating the miniaturization of the plasma generator 100.

[0080] In some embodiments, the material composition of the dielectric structure 13 includes at least one of a thermochromic material and an ultraviolet color-developing material, so that the dielectric structure 13 forms the display structure 2.

[0081] This configuration allows the dielectric structure 13 to be reused as a display structure 2. The dielectric structure 13 has a first display state and a second display state, and it can change color under heat or ultraviolet light. When the plasma generator 100 is operating normally, the dielectric structure 13 can change color in response to at least one physical radiation, such as generated heat or ultraviolet light, to present the first display state. When the plasma generator 100 is not operating, the dielectric structure 13 displays its original color to present the second display state. By using the dielectric structure 13 as the display structure 2, the operating status of the plasma generator 100 can be reflected more quickly and accurately. It also reduces the number of components in the plasma generator 100 and eliminates the need for additional display structures 2, making the assembly and disassembly of the plasma generator 100 more convenient.

[0082] In some embodiments, at least a portion of the dielectric structure 13 is configured as a light-transmitting structure, and a closed filling cavity is formed within the dielectric structure 13, which 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 filled with a rare gas, and at least a portion of the dielectric structure 13 is light-transmitting. For example, the entire dielectric structure 13 can be made of quartz or a light-transmitting plastic material, or part of the cavity wall can be made of a light-transmitting material. Thus, the dielectric structure 13 can be reused as a rare gas luminescent structure 23. This configuration eliminates the need for an additional bulb as the display structure 3, reducing the number of components used in the plasma generator 100. When the plasma generator 100 is operating normally and generating an alternating electric field, the rare gas luminescent structure 23 formed by the dielectric structure 13 can be positioned at a higher field strength within the alternating electric field, thereby better exciting the rare gas to emit light, increasing the brightness, and allowing the user to better observe and judge the operating status of the plasma generator 100.

[0084] Please see 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 covers 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 a portion of the first electrode 11 can be configured as a strip structure, such as a linear electrode or a rectangular electrode. The dielectric structure 13 covers the outer side of the portion of the first electrode 11 configured as a strip structure. The dielectric structure 13 can be attached to the outer surface of the first electrode 11 or can be spaced apart from the first electrode 11, for example, configured as a circular tube, square tube or other polygonal tube surrounding the strip structure. The second electrode 12 is disposed outside the dielectric structure 13. This arrangement, with the first electrode 11 and the second electrode 12 respectively disposed on the inner and outer sides of the dielectric structure 13, and the first electrode 11 and the second electrode 12 separated by the dielectric structure 13, can make the structure of the plasma generator 100 more compact.

[0086] In this embodiment, the display structure 2 can be disposed on the dielectric structure 13. For example, at least one of a thermochromic layer and an ultraviolet color-developing layer can be disposed on the outer surface of the dielectric structure 13. Alternatively, at least one of a thermochromic 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 rare gas can also be disposed within the dielectric structure 13, and at least a portion of the outer surface of the dielectric structure 13 can be light-transmitting, thereby making the dielectric structure 13 a rare gas light-emitting structure 23. Furthermore, at least one of a thermochromic layer and an ultraviolet color-developing layer can be disposed on the surface of the first electrode 11 not enclosed by the dielectric structure 13, and at least one of a thermochromic layer and an ultraviolet color-developing layer can also be disposed 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, with the display structure 2 located near the second electrode 12, so that when the plasma generator 100 is working 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 present the first display state in response to at least one physical radiation of heat, ultraviolet light and electromagnetic field generated when the plasma is generated.

[0087] Optionally, the dielectric structure 13 can be made of a rigid material such as quartz or ceramic 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 configured as flexible and deformable structures, for example, the first electrode 11 and the second electrode 12 can be made of flexible and fully flexible metal wire or metal strip; the dielectric structure 13 can be made of resin, plastic, silicone rubber, PVC (polyvinyl chloride), etc. to form an insulating and flexible insulating outer skin, or several quartz or ceramic particles can be attached to a flexible carrier. This configuration allows the plasma generator 100 to be bent and coiled according to different usage environments and installation spaces to suit different application scenarios.

[0088] Please see 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 configured as a helical electrode extending spirally along the outer surface of the dielectric structure 13, or as a mesh electrode or other structures. This configuration increases the discharge area between the first electrode 11 and the second electrode 12, resulting in more plasma being generated between them.

[0089] Please see Figures 6 to 9 In some embodiments, at least part of the dielectric structure 13 is a planar dielectric structure, and the first electrode 11 and the second electrode 12 are respectively set as two sides of the planar dielectric structure facing each other.

[0090] In this embodiment, at least a portion of the dielectric structure 13 is configured as a planar dielectric structure. For example, the entire dielectric structure 13 can be configured as a plate structure, or it can be configured as a shell structure with planar sidewalls. The planar dielectric structure is disposed between the first electrode 11 and the second electrode 12. 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. The first electrode 11 and the second electrode 12 can both be linear electrodes, or both can be planar electrodes, or one of the first electrode 11 and the second electrode 12 can be configured as a flat strip electrode; no limitation is made here.

[0091] Please see Figures 6 to 9 In some embodiments, the first electrode 11 is a plate-shaped electrode or a strip electrode disposed opposite to the planar dielectric structure. When a plate-shaped electrode is disposed opposite to the planar dielectric structure, a large reaction area is formed on one side of the first electrode 11, allowing for the ionization of a larger area of ​​air to generate plasma. Setting the first electrode 11 as a strip electrode, such as a linear electrode or a rectangular electrode, allows for control of the plasma generation and diffusion areas, facilitating the utilization of the plasma.

[0092] Please see Figures 6 to 9 In some embodiments, the second electrode 12 is a plate-shaped electrode or a strip electrode disposed opposite to the planar dielectric structure. When a plate-shaped electrode is disposed opposite to the planar dielectric structure, a larger reaction area is formed on one side of the second electrode 12, allowing for the ionization of a larger area of ​​air to generate plasma. Constructing the second electrode 12 as a strip electrode, such as a linear electrode or a rectangular electrode, allows for control of the plasma generation and diffusion areas, facilitating the utilization of 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 can be set as a strip electrode and the second electrode 12 can be set as a plate electrode. Alternatively, when both the first electrode 11 and the second electrode 12 are strip electrodes, the end of the second electrode 12 can be blunted to the end of the first electrode 11. In both cases, the field strength on the side of the first electrode 11 can be higher than that on the side of the second electrode 12, thereby causing more plasma to be concentrated on the side of the first electrode 11 with higher field strength.

[0094] Please see 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-shaped electrode; or, the first electrode 11 and the second electrode 12 have tips disposed opposite to each other.

[0095] In this embodiment, the reaction module 1 in the plasma generator 100 ionizes air using corona discharge to generate plasma. The first electrode 11 and the second electrode 12 are arranged opposite each other, with at least one of them having a pointed tip. This can be achieved by configuring the first electrode 11 as a plate-shaped electrode and the second electrode 12 as a needle-shaped electrode; alternatively, the first electrode 11 can be a needle-shaped electrode and the second electrode 12 as a plate-shaped electrode; or both the first electrode 11 and the second electrode 12 can have a pointed tip pointing towards the other electrode. This arrangement...

[0096] The display structure 2 can be constructed by providing at least one of a thermochromic layer and an ultraviolet color-developing layer on the surface of the first electrode 11, or by providing at least one of a thermochromic layer and an ultraviolet color-developing layer on the second electrode 12, or by providing at least one of a thermochromic structure 21, an ultraviolet color-developing structure 22, and a rare gas luminescent structure 23 near the first electrode 11, or by providing at least one of a thermochromic structure 21, an ultraviolet color-developing structure 22, and a rare gas luminescent structure 23 near the second electrode 12.

[0097] Please see Figures 11 to 13 In some embodiments, when one of the first electrode 11 and the second electrode 12 is provided with a tip, the display structure 2 can be provided on the surface of the electrode with the tip, which is provided with at least one of a thermosensitive color-changing layer and an ultraviolet color-developing layer. Alternatively, at least one of a thermosensitive color-changing structure 21, an ultraviolet color-developing structure 22, and a rare gas luminescent structure 23 can be provided near the electrode as the display structure 2. This arrangement allows the display structure 2 to be near the electrode with a higher field strength, thereby responding better and more sensitively to heat, ultraviolet light, or alternating electric fields to change color or emit light.

[0098] Please see Figure 1 In some embodiments, the plasma generating device 100 further includes a housing 3, which has a mounting cavity 31 and an opening communicating with the mounting cavity 31, and the reaction module 1 is disposed in the mounting cavity 31.

[0099] In this embodiment, a housing 3 is provided in the plasma generator 100, and the reaction module 1 is housed in the mounting cavity 31 of the housing 3. The plasma generated by the plasma generator 100 during operation can diffuse outward from the opening of the housing 3, which facilitates control of the plasma diffusion position. Furthermore, by integrating the dielectric structure 13, the first electrode 11, and the second electrode 12 into an integral structure, the relative positions of the various structures of the reaction module 1 can be kept stable, improving the performance stability of the plasma generator 100. Moreover, when the plasma generator 100 is applied to electrical equipment, the plasma generator 100 can be disassembled and assembled as a whole, eliminating the need to disassemble and assemble the individual components of the plasma generator 100 separately in the electrical equipment, thus improving ease of use.

[0100] In this embodiment, the display structure 2 can be disposed 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 disposed on the housing 3, or for example, the display structure 2 can be fixed on the housing 3, or the housing 3 can be reused as the display structure 2; in addition, the display structure 2 can also be disposed on the outside of the housing 3 and disposed separately from the housing 3, which is not limited here.

[0101] Please see Figure 1 In some embodiments, the display structure 2 is separately disposed from the housing 3; or, the display structure 2 is disposed within the housing 3.

[0102] In this embodiment, the display structure 2 can be separately disposed from the housing 3. For example, the display structure 2 can be disposed on at least one of the dielectric structure 13, the first electrode 11, and the second electrode 12 located inside the housing 3. Alternatively, the display structure 2 can be disposed on the outside of the housing 3. For example, a support structure such as a bracket can be provided on the outside of the housing 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 to the equipment.

[0103] Alternatively, the display structure 2 can be disposed on the housing 3, for example, the display structure 2 can be disposed on the surface of the housing 3. The housing 3 can also be reused as at least one of the thermosensitive color-changing structure 21, the ultraviolet color-producing structure 22 and the rare gas light-emitting structure 23. For specific implementation methods, please refer to the following embodiments, which will not be elaborated here.

[0104] Please see Figure 1In some embodiments, the display structure 2 is located around the opening of the housing 3. This arrangement allows the display structure 2 to be positioned close to the plasma generation area, enabling it to respond more sensitively to physical radiation such as heat, ultraviolet light, and electromagnetic fields generated during plasma generation and switch display states accordingly. Furthermore, the display structure 2 is exposed on the outside of the housing 3, making it convenient for the user to observe the display state of the display structure 2 to determine the operating status of the plasma generator 100.

[0105] Please see 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 a rare gas luminescent structure 23, a thermosensitive color-changing structure 21, and an ultraviolet color-developing structure 22 can be fixed on the outer surface of the housing 3. This arrangement facilitates the user's observation of the display status of the display structure 2 to determine the operating status of the plasma generator 100. Furthermore, by using the housing 3 to support the display structure 2, it is unnecessary to set additional structural components to fix the color-developing device in the plasma generator 100, thereby reducing the number of components in the plasma generator, simplifying the structure of the plasma generator 100, and also facilitating the miniaturization of the plasma generator 100.

[0106] In some embodiments, the surface of the housing 3 is provided with at least one of a thermochromic layer and an ultraviolet color-developing layer to form a display structure 2 on the surface of the housing 3.

[0107] In this embodiment, a thermochromic layer can be provided on at least a portion of the surface of the housing 3 as a thermochromic structure 21, and an ultraviolet color-developing layer can be provided on at least a portion of the surface of the housing 3 as an ultraviolet color-developing structure 22. Alternatively, a thermochromic layer can be provided on a portion of the surface of the housing 3, and an ultraviolet color-developing layer can be provided on another portion of the surface. This configuration, where at least one of the thermochromic structure 21 and the ultraviolet color-developing structure 22 is a coating on the surface of the housing 3, eliminates the need for additional structural components to fix the display structure 2 in the plasma generator 100, and also reduces the volume of the combined structure of the housing 3 and the display structure 2, thus facilitating the miniaturization of the plasma generator 100.

[0108] In some embodiments, the material composition of the housing 3 includes at least one of a thermochromic material and an ultraviolet color-developing material, so that the housing 3 serves as the display structure 2.

[0109] In this design, a thermochromic material can be added to the material composition of the housing 3, enabling the housing 3 to change color according to temperature changes; alternatively, an ultraviolet (UV) color-developing material can be added to the material composition of the housing 3, enabling the housing 3 to change color in response to UV light; furthermore, both thermochromic and UV color-developing materials can be added to the material composition of the housing 3 simultaneously, or the material composition at different locations on the housing 3 can include both thermochromic and UV color-developing materials respectively. This configuration reuses the housing 3 as the display structure 2. The operating status of the plasma generator 100 can be intuitively determined by the changes in the display state of the housing 3. The plasma generator 100 has a relatively simple structure and is 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, and a filling cavity is formed inside the shell wall. 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 a portion of the shell wall of the housing 3 has a hollow filling cavity, which is filled with at least one rare gas selected from helium, neon, argon, krypton, xenon, and radon. The shell wall enclosing the filling cavity is light-transmitting; for example, the entire housing 3 can be made of quartz or translucent plastic, or a portion of the cavity wall can be made of a translucent material. Thus, the housing 3 can be reused as a rare gas light-emitting structure 23. This configuration eliminates the need for an additional bulb as the display structure 3, reducing the number of components used in the plasma generator 100. When the plasma generator 100 is operating normally and generating an alternating electric field, the rare gas in the filling cavity emits light under the influence of the electric field and shines through the housing 3, making it easy for the user to observe and judge the operating status of the plasma generator 100.

[0112] The present invention also proposes an electrical device, which includes a plasma generator 100 as described in any of the foregoing embodiments. 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 is as described in the foregoing embodiments. Since this electrical device adopts all the technical solutions of all the foregoing embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the foregoing embodiments, which will not be elaborated further here.

[0113] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
