Description

Technical Field

[0001] The present invention relates to the technical field of air treatment, and specifically provides a plasma generation module, a plasma generation device, and an air conditioner. Background Art

[0002] An air conditioner usually adjusts the temperature of an indoor space by exchanging heat between indoor air and an indoor heat exchanger. After being used for a long time like this, a large amount of bacteria, viruses, and particulate matter will accumulate inside. When the indoor air exchanges heat with the indoor heat exchanger, it will carry the bacteria, viruses, and particulate matter in the air conditioner into the indoor space, resulting in a decline in the air quality of the indoor space and seriously endangering people's health. Moreover, since the doors and windows are usually closed during the operation of the air conditioner, peculiar smells will be generated indoors. People's activities indoors will also generate cigarette smells, toilet odors, etc. Families with pets will also generate corresponding peculiar smells, which seriously affect the comfort level.

[0003] Therefore, people usually configure a sterilization device on the air conditioner for sterilization treatment and an odor removal device for odor removal treatment, which is costly. In the prior art, ozone devices and silver ion devices can usually only perform sterilization treatment, and activated carbon filters and photocatalyst devices can usually only perform odor removal treatment. Configuring two devices at the same time is costly and requires a lot of space. Moreover, ozone itself is a harmful substance, and it needs to be harmlessly treated while using it for sterilization, resulting in a complex structure of the ozone device and a high overall cost. The initiative of silver ion sterilization is poor, and air can only be sterilized after passing through the silver ion device. The efficiency of the activated carbon filter for odor removal is poor. To improve the odor removal effect, usually a large number of activated carbon filters need to be configured, which requires a large amount of space, generates wind resistance at the same time, and needs to be replaced regularly. Otherwise, it will overflow and cause secondary pollution after adsorption saturation. The photocatalyst device usually uses a light source and a catalyst mesh in combination, which also requires a relatively large amount of space, generates wind resistance at the same time, and has a high cost. The negative ion device can perform both sterilization and odor removal treatment, but negative ions are extremely easy to be adsorbed and neutralized by particulate matter (such as dust, etc.) due to carrying negative charges, and have a short lifespan, and are consumed within a short distance range and are difficult to reach a position far away from it, so the sterilization and odor removal effects are limited.

[0004] Correspondingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] The present invention aims to solve the above technical problems, that is, to solve the problems of low efficiency of sterilization and odor removal, large space occupation, high cost, etc. of the sterilization and odor removal devices in the prior art.

[0006] In a first aspect, the present invention provides a plasma generation module. The plasma generation module (11) includes at least one plasma generation component (111). The plasma generation component (111) includes a first electrode (1111), a second electrode (1112), and an insulating dielectric layer (1113). The first electrode (1111) and the second electrode (1112) are respectively disposed on both sides of the insulating dielectric layer (1113), and the first electrode (1111) and the second electrode (1112) are in contact with each other on both sides of the insulating dielectric layer (1113). When the plasma generation component (111) is powered on, the electrical properties of the first electrode (1111) and the second electrode (1112) are opposite.

[0007] In a preferred technical solution of the above plasma generation module, an installation position is formed on the side of the insulating dielectric layer (1113), and the first electrode (1111) and / or the second electrode (1112) is embedded in the installation position.

[0008] In a preferred technical solution of the above plasma generation module, the size of one of the first electrode (1111) and the second electrode (1112) is smaller than the size of the other.

[0009] In a preferred technical solution of the above plasma generation module, a first through hole (11111) is provided on the first electrode (1111), and the first through hole (11111) penetrates the first electrode (1111) along the thickness direction of the first electrode (1111); and / or

[0010] A second through hole (11121) is provided on the second electrode (1112), and the second through hole (11121) penetrates the second electrode (1112) along the thickness direction of the second electrode (1112).

[0011] In a preferred technical solution of the above plasma generation module, the plasma generation module (11) further includes a base (12). The plasma generation component (111) is clamped in the base (12), and the plasma generation module (11) is disposed on a target component through the base (12).

[0012] In a preferred technical solution of the above plasma generation module, the plasma generation module (11) further includes a housing (13). The housing (13) is disposed on the base (12). A ventilation structure (131) is provided on the housing (13), and the housing (13) covers the outside of the plasma generation module (11).

[0013] In the preferred technical solution of the above plasma generation module, the plasma generation module (11) includes a plurality of plasma generation components (111), at least some of the plasma generation components (111) are arranged at intervals along the length direction of the base (12), and at least a part of the ventilation structure (131) is aligned with the gap between two adjacent plasma generation components (111).

[0014] In the preferred technical solution of the above plasma generation module, the plasma generation component (111) includes two insulating dielectric layers (1113), and one of the first electrode (1111) and the second electrode (1112) is arranged between the two insulating dielectric layers (1113), and the other of the first electrode (1111) and the second electrode (1112) is respectively arranged on the side parts of the two insulating dielectric layers (1113) facing away from each other.

[0015] In the technical solution of the present invention, the plasma generation module includes at least one plasma generation component, and each plasma generation component includes a first electrode, a second electrode and an insulating dielectric layer. The first electrode and the second electrode are respectively arranged on both sides of the insulating dielectric layer, and the first electrode and the second electrode are respectively in contact with the insulating dielectric layer. When the plasma generation component is powered on and operates, the electric polarities of the first electrode and the second electrode are opposite. In this way, the two electrodes and the insulating dielectric layer are assembled together to form a plasma generation component. When the plasma generation component is powered on, under the action of the insulating dielectric layer, a uniform electric field can be formed between the two electrodes. When air flows through the plasma generation component, oxygen, water molecules, etc. in the air are ionized to generate high-density and high-energy plasma, rather than generating harmful ozone. Through this plasma, the air can be quickly sterilized and deodorized, and the energy of the plasma is relatively high, and it can diffuse into the space where the plasma generation module is located along with the air flow, further sterilizing and deodorizing the air and objects in the space. Compared with negative ions, better sterilization and deodorization effects can be obtained.

[0016] Further, the size of one of the first electrode and the second electrode is smaller than that of the other. In this way, when the plasma generation module is powered on, an electric field similar to a spindle shape can be formed between the first electrode and the second electrode, effectively increasing the area covered by the electric field and improving the ionization efficiency.

[0017] Further, a first through-hole and a second through-hole are respectively provided on the first electrode and the second electrode. The first through-hole and the second through-hole respectively penetrate the first electrode and the second electrode along the thickness directions of the first electrode and the second electrode. When the plasma generating component is powered on, a discharge point can be formed at each of the first through-hole and the second through-hole, which is equivalent to forming a plurality of discharge points on the two electrodes that can ionize air to generate plasma, effectively improving the ionization efficiency and enabling the generation of more plasma.

[0018] Further, the plasma generating component includes two insulating dielectric layers. One of the first electrode and the second electrode is disposed between the two insulating dielectric layers, and the other of the first electrode and the second electrode is respectively disposed on the side portions of the two insulating dielectric layers facing away from each other. In this way, it is equivalent to a plasma generating component having two pairs of first electrodes and second electrodes, capable of forming two electric fields, thereby enabling the ionization to generate more plasma.

[0019] In a second aspect, the present invention further provides a plasma generating device, which includes the plasma generating module according to any one of the foregoing solutions.

[0020] It should be noted that this plasma generating device has all the technical effects of the foregoing plasma generating module, which will not be elaborated herein.

[0021] In a third aspect, the present invention further provides an air conditioner, which is configured with the plasma generating module or the plasma generating device according to any one of the foregoing solutions.

[0022] It should be noted that this air conditioner has all the technical effects of the foregoing plasma generating module or plasma generating device, which will not be elaborated herein. Description of the Drawings

[0040] The preferred implementation manners of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. It should be noted that although the above is described by taking the plasma generating device arranged in a wall-mounted air conditioner as an example, it is obvious that it can also be arranged in other types of air conditioners such as cabinet air conditioners, central air conditioners, duct machines, window machines, or other types of air purification equipment such as air purifiers and disinfection machines.

[0041] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "inner", "outer", "left", "right", etc. are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In addition, it should also be noted that in the description of the present application, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0043] At present, common ozone devices and silver ion devices can usually only perform sterilization treatment, and activated carbon filter screens and photocatalyst devices can usually only perform odor removal treatment. To perform sterilization and odor removal treatment on air, two devices need to be configured simultaneously, and the sterilization and odor removal efficiency of each device is relatively low, occupying a large space and having a high cost. The negative ions generated by the negative ion device that can perform sterilization and odor removal treatment simultaneously are extremely easy to be adsorbed and neutralized, with a short lifespan and difficult to reach positions far away from it, resulting in limited sterilization and odor removal effects. Therefore, the plasma generation module of the present application includes at least one plasma generation component, each plasma generation component includes a first electrode and a second electrode with opposite electric charges, and an insulating dielectric layer disposed between the first electrode and the second electrode, so as to be able to form a uniform electric field between the first electrode and the second electrode, ionize air to generate plasma, and perform sterilization and odor removal treatment on air through the plasma.

[0044] The following will Figures 1 to 14 describe possible implementation manners of the plasma generation device of the present invention.

[0045] As Figures 1 to 6As shown in the figure, the plasma generating device 1 includes at least one plasma generating module 11, and the plasma generating module 11 includes at least one plasma generating component 111. The plasma generating component 111 includes a first electrode 1111, a second electrode 1112, and an insulating dielectric layer 1113. The first electrode 1111, the second electrode 1112, and the insulating dielectric layer 1113 are all substantially rectangular structures. The first electrode 1111 and the second electrode 1112 are respectively disposed on both sides of the insulating dielectric layer 1113, and the two electrodes are respectively attached to the side portions of the insulating dielectric layer 1113, so that the two electrodes and the insulating dielectric layer 1113 are assembled together to form the plasma generating component 111. When the plasma generating component 111 is powered on, the electric polarities of the first electrode 1111 and the second electrode 1112 are opposite, and there is a potential difference between the two electrodes, forming a high-voltage electric field. Under the action of the insulating dielectric layer 1113, the electric field formed between the two electrodes can be made more uniform. In this way, when air flows through the plasma generating component 111, only oxygen, water molecules, etc. in the air are ionized to generate high-density and high-energy plasma, rather than generating harmful ozone. Plasma generally includes ionization clusters such as positive and negative ions, electrons, and reactive oxygen species (ROS). The charged particles can attach to microparticles (such as dust) to increase their weight and cause them to settle or be captured by a filter. The reactive oxygen species can decompose and transform harmful gases (VOCs, etc.) and inactivate microorganisms (such as bacteria, viruses, etc.) in the air, turning them into harmless or relatively stable substances. Thus, it can be seen that the air can be quickly sterilized and deodorized by this plasma, and the energy of the plasma is relatively high, and it can diffuse into the space where the plasma generating device 1 is located along with the air flow, further sterilizing and deodorizing the air and objects in the space. Compared with negative ions, a better sterilization and deodorization effect can be obtained.

[0046] It should be noted that the plasma generating device 1 of the present application is powered by an AC high-voltage power supply (such as a voltage of 2000V - 3000V, etc.). During the working process, the electric polarities of the first electrode 1111 and the second electrode 1112 are always opposite. Specifically, when the first electrode 1111 is the positive electrode, the second electrode 1112 is the negative electrode, and when the first electrode 1111 is the negative electrode, the second electrode 1112 is the positive electrode.

[0047] In a possible implementation manner, the first electrode 1111 and the second electrode 1112 can be prepared from metal materials such as copper, stainless steel, and tungsten, and the insulating dielectric layer 1113 can be prepared from inorganic insulating materials with a relatively large dielectric constant such as ceramics and glass. Preferably, the first electrode 1111 and the second electrode 1112 are made of brass, and the insulating dielectric layer 1113 is made of ceramics.

[0048] As Figures 1 to 6As shown, each plasma generation component 111 includes two insulating dielectric layers 1113. A first electrode 1111 is disposed between the two insulating dielectric layers 1113, and a second electrode 1112 is respectively disposed on side portions of the two insulating dielectric layers 1113 facing away from each other. According to Figure 6 shown in, the plasma generation component 111 is composed of a second electrode 1112, an insulating dielectric layer 1113, a first electrode 1111, an insulating dielectric layer 1113, and a second electrode 1112 arranged in sequence from left to right. In this way, it is equivalent to a plasma generation component 111 having two pairs of first electrodes 1111 and second electrodes 1112, capable of forming two electric fields, thereby being able to ionize and generate more plasma. Moreover, the size of the first electrode 1111 is smaller than that of the second electrode 1112, so that an electric field similar to a spindle shape can be formed between the first electrode 1111 and the second electrode 1112. Such an electric field has a larger ionization area, can obtain a higher ionization efficiency, and thus can generate more plasma. Obviously, it is also possible to dispose the second electrode 1112 between the two insulating dielectric layers 1113.

[0049] It should be noted that it is also possible that the size of the second electrode 1112 is smaller than that of the first electrode 1111. Of course, the sizes of the first electrode 1111 and the second electrode 1112 can also be the same.

[0050] It should be noted that each plasma generation component 111 can also include only one insulating dielectric layer 1113. In this case, the plasma generation component 111 includes one first electrode 1111 and one second electrode 1112. Obviously, each plasma generation component 111 can also include three, four, five or more insulating dielectric layers 1113. In this case, the first electrode 1111 and the second electrode 1112 are disposed on side portions of each insulating dielectric layer 1113 in an alternating manner. Taking the plasma generation component 111 including four insulating dielectric layers 1113 as an example, the plasma generation component 111 can be stacked in the manner of a first electrode 1111, an insulating dielectric layer 1113, a second electrode 1112, an insulating dielectric layer 1113, a first electrode 1111, an insulating dielectric layer 1113, a second electrode 1112, an insulating dielectric layer 1113, and a first electrode 1111.

[0051] For the convenience of description, hereinafter, taking the plasma generation component 111 including a second electrode 1112, an insulating dielectric layer 1113, a first electrode 1111, an insulating dielectric layer 1113, and a second electrode 1112 arranged in sequence as an example and in combination with Figures 1 to 13 to elaborate in detail on possible implementation manners of the plasma generation device 1 of the present invention.

[0052] As Figures 1 to 6As shown, on the relatively arranged side parts of the two insulating dielectric layers 1113, first grooves 11131 serving as installation positions are formed by inward depression. The first grooves 11131 are generally rectangular, and the size of the groove bottom is approximately equivalent to the size of the first electrode 1111. On the outer sides of the two insulating dielectric layers 1113, second grooves 11132 serving as installation positions are formed by inward depression. The second grooves 11132 are generally rectangular, and the size of the groove bottom is approximately equivalent to the size of the second electrode 1112. Mounting holes 11133 are also provided on the two insulating dielectric layers 1113, and the mounting holes 11133 are located below the installation positions. During assembly, fasteners (such as screws, bolts, etc.) are passed through the two mounting holes 11133 to fasten the two insulating dielectric layers 1113 to each other. The two relatively arranged first grooves 11131 are fastened to each other to form an installation space, and the first electrode 1111 is clamped in this installation space. Then, the two second electrodes 1112 are respectively embedded in the second grooves 11132 on the outer sides of the two insulating dielectric layers 1113, and then the fasteners are tightened. In this way, one first electrode 1111, two second electrodes 1112, and two insulating dielectric layers 1113 are assembled together to form a plasma generating assembly 111. When assembled, the two second electrodes 1112 are respectively located on the outer sides of the plasma generating assembly 111, and the first electrode 1111 is located between the two insulating dielectric layers 1113. Moreover, the outer edges of the first electrode 1111 and the second electrode 1112 are respectively wrapped by the outer edges of the insulating dielectric layers 1113. In this way, the electric field generated between the first electrode 1111 and the second electrode 1112 can be made more uniform, and the occurrence of ozone due to tip discharge at the outer edges of the first electrode 1111 and the second electrode 1112 can be avoided. To ensure the stable installation of the second electrode 1112 on the outer sides of the two insulating dielectric layers 1113, a limiting structure can be provided at the top of the second groove 11132. The limiting structure can be a circumferentially distributed structure or a pair of symmetrically arranged limiting pieces, etc.

[0053] It should be noted that the first electrode 1111 and the second electrode 1112 can also be fixedly arranged on both sides of the insulating dielectric layer 1113 by means of bonding, clamping, plugging, etc. Taking clamping as an example, buckles are respectively provided on both sides of the insulating dielectric layer 1113, and clamping holes 1213 are respectively provided at corresponding positions on the first electrode 1111 and the second electrode 1112. The first electrode 1111 and the second electrode 1112 are respectively arranged on both sides of the insulating dielectric layer 1113 through the matching of the buckles and the clamping holes 1213. Without departing from the basic principle of the present application, those skilled in the art can flexibly select according to specific application scenarios as long as the first electrode 1111 and the second electrode 1112 can be arranged on both sides of the insulating dielectric layer 1113.

[0054] As Figures 1 to 6As shown, a plurality of first through-holes 11111 are provided on the first electrode 1111, and a plurality of second through-holes 11121 are provided on the second electrode 1112. The first through-holes 11111 and the second through-holes 11121 are both substantially circular holes, and penetrate the first electrode 1111 and the second electrode 1112 along the thickness directions of the first electrode 1111 and the second electrode 1112 respectively. The plurality of first through-holes 11111 and the plurality of second through-holes 11121 are respectively arranged on the first electrode 1111 and the second electrode 1112 in an array manner, forming a structure similar to a honeycomb. When the plasma generating assembly 111 is energized and a high-voltage electric field is formed between the first electrode 1111 and the second electrode 1112, a discharge point can be formed at each of the first through-holes 11111 and the second through-holes 11121, which is equivalent to forming a plurality of discharge points on the two electrodes that can ionize air to generate plasma, effectively improving the ionization efficiency and being able to generate more plasma.

[0055] In order to more clearly understand the electric field distribution of the plasma generating assembly 111, the inventor of the present application performed a simulation in COMSOL. For the specific results, please refer to Figures 10 to 13 . Among them, COMSOL is a multi-physics simulation software with wide applications. The specific parameters and simulation process thereof will not be elaborated here. It can be seen that under the action of the insulating dielectric layer 1113, the electric field generated by the plasma generating assembly 111 is relatively uniform, and the potential distribution is also relatively uniform. Under the action of such an electric field, ionizing air will only generate plasma and will not generate toxic ozone.

[0056] It should be noted that the first through-holes 11111 and the second through-holes 11121 can also be set as holes in other possible shapes such as polygons, rectangles, squares, ellipses, etc. Of course, only the first through-holes 11111 can be provided on the first electrode 1111 or only the second through-holes 11121 can be provided on the second electrode 1112. Obviously, through-holes can also not be provided on both the first electrode 1111 and the second electrode 1112, and plasma can be generated only by surface discharge of the first electrode 1111 and the second electrode 1112.

[0057] Continue to refer to Figures 1 to 6, the plasma generating assembly 111 further includes an insulating member 1114. The size of the insulating member 1114 is smaller than that of the insulating dielectric layer 1113, and is substantially equivalent to the size and shape of the portion of the insulating dielectric layer 1113 except for the first groove 11131 and the second groove 11132 provided thereon. A screw hole 11141 is provided thereon. During assembly, the two insulating members 1114 are respectively disposed outside the two insulating dielectric layers 1113, and the screw holes 11141 thereon are respectively aligned with the mounting holes 11133. The fasteners sequentially pass through one insulating member 1114, the two insulating dielectric layers 1113, and the other insulating member 1114, and the two insulating members 1114 are respectively fixedly disposed outside the two insulating dielectric layers 1113. Through the insulating member 1114, the insulation between two adjacent plasma generating assemblies 111 can be ensured, and at the same time, the second electrode 1112 can be blocked from falling away from the insulating dielectric layer 1113.

[0058] As Figures 1 to 9 shown, the plasma generating device 1 further includes a base 12. The base 12 is generally a long strip-shaped structure, including a first part 121 and a second part 122. The first part 121 is generally an inverted cover-shaped structure, and the inner wall of its circumferential side wall is recessed inward to form four clamping grooves 1211. The four clamping grooves 1211 are grouped in pairs and symmetrically disposed inside the two long side walls of the circumferential side wall and distributed along the length direction of the base 12. The second part 122 is generally a rectangular plate-shaped structure, and two mounting plates 1221 are provided on the side portion thereof facing the first part 121. The mounting plates 1221 extend along the circumference of the second part 122, and four clamping blocks 1222 are provided at corresponding positions. The four clamping blocks 1222 are grouped in pairs and symmetrically disposed outside the two long sides of the mounting plates 1221 and distributed along the length direction of the base 12. The first part 121 and the second part 122 are snapped together through the matching connection of the clamping grooves 1211 and the corresponding clamping blocks 1222. Obviously, it is also possible to provide clamping blocks 1222 on the circumferential side wall of the first part 121, and clamping grooves 1211 or clamping holes 1213 on the mounting plates 1221 of the second part 122. The present application does not specifically limit the way in which the first part 121 and the second part 122 are snapped together, as long as the first part 121 and the second part 122 can be snapped together.

[0059] Obviously, the plasma generating assembly 111 may also not include the insulating member 1114. In this case, the base 12 is made of an insulating material, and ensuring the distance between two adjacent plasma generating assemblies 111 can also ensure the insulation between two adjacent plasma generating assemblies 111.

[0060] Continue to refer to Figures 1 to 9, the plasma generating device 1 includes two plasma generating modules 11, and each plasma generating module 11 includes five plasma generating components 111. The five plasma generating components 111 are arranged at intervals along the length direction of the base 12. When assembled, there is a gap between two adjacent plasma generating components 111. In this way, when air flows through the plasma generating device 1, it can be fully ionized by the plasma generating components 111 surrounding it on both sides to generate plasma, so that the air can be sterilized and deodorized more fully. At both sides of the lower ends of each insulating dielectric layer 1113 and insulating part 1114, a clamping space 113 is respectively formed, and a strip-shaped electrode 112 is arranged in each of the two clamping spaces 113. The lower ends of the first electrode 1111 and the second electrode 1112 extend downward, and clamping positions are formed at their ends. All the first electrodes 1111 are clamped to the strip-shaped electrode 112 on the right side, and all the second electrodes 1112 are clamped to the strip-shaped electrode 112 on the left side. In this way, the two types of electrodes of each plasma generating module 11 are connected together, which is more convenient for the overall control of the plasma generating module 11. Obviously, each plasma generating module 11 can also be configured with a base 12 respectively.

[0061] It should be noted that the plasma generating device 1 can also include only one, or three, four, five or more plasma generating modules 11. Each plasma generating module 11 can also include four, three, two or fewer, or six, seven, eight or more plasma generating components 111. In this embodiment, the specific number of plasma generating modules 11 included in the plasma generating device 1 and the specific number of plasma generating components 111 included in each plasma generating module 11 are not limited.

[0062] It should be noted that in this embodiment, the length direction of the base 12 is approximately Figure 7 the horizontal direction in

[0063] Continue to refer to Figures 1 to 9, on the side of the second part 122 facing the first part 121, there is also an installation platform 1223. The installation platform 1223 is located inside the installation plate 1221 and includes two relatively arranged strip-shaped blocks. The two strip-shaped blocks are arranged parallel to each other and there is a gap between them. On the sides of the two strip-shaped blocks facing away from each other, there are respectively strip-shaped protrusions 1224, and the strip-shaped protrusions 1224 extend along the length direction of the base 12. On the side of the first part 121 facing the second part 122, there is a perforation 1212 formed, and the perforation 1212 is generally a rectangular hole. At the lower ends of the two insulating dielectric layers 1113, there is a recessed area 11134 that is generally arched. The distance between the opposite sides of the recessed area 11134 is approximately equal to the distance between the two sides of the two strip-shaped blocks facing away from each other. The two opposite sides are recessed away from each other to form a clamping position 11135. During assembly, the lower ends of the two insulating dielectric layers 1113 are passed through the perforation 1212, and with a little force, the two strip-shaped blocks are slightly deformed towards each other, so that the clamping position 11135 is matched and connected with the strip-shaped protrusion 1224, thereby clamping the plasma generating assembly 111 on the base 12. Five plasma generating assemblies 111 are sequentially clamped on the base 12 along the length direction of the base 12. When installed, there is a gap between two adjacent plasma generating assemblies 111. That is to say, the five plasma generating assemblies 111 are arranged at intervals along the length direction of the base 12 on the base 12. It should be noted that the perforation 1212 can also be set as a hole in other possible shapes such as square, circular, elliptical, polygonal, etc.

[0064] It should be noted that the installation platform 1223 can also be composed of only one strip-shaped block, and the width of the strip-shaped block is approximately equal to the distance between the opposite sides of the recessed area 11134 of the insulating dielectric layer 1113. Obviously, it can also be that a groove is formed on the installation platform 1223, and the opposite sides of the recessed area 11134 are correspondingly formed with hooks inward, and the insulating dielectric layer 1113 is clamped on the installation platform 1223 through the matching of the hooks and the groove. Of course, the lower end of the insulating dielectric layer 1113 may not form a recessed area 11134. In this case, a hook or a buckle can be formed outward on the outer edge of the lower end of the insulating dielectric layer 1113, and the second part 122 is provided with a card hole 1213 or a card slot 1211, etc. at the corresponding position. It should also be noted that the base 12 may not be formed by buckling the first part 121 and the second part 122 with each other, but is an integral body, and the plasma generating assembly 111 is directly clamped on the base 12. Of course, the plasma generating assembly 111 can also be arranged on the base 12 by other possible methods such as plugging, bonding, screwing, etc.

[0065] Such as Figures 1 to 9As shown in the figure, the plasma generating device 1 further includes two housing cases 13. A ventilation structure 131 is provided on the housing case 13. The housing case 13 is generally an arched structure with openings 1214 at both ends. The ventilation structure 131 includes a first ventilation hole 1311 and a second ventilation hole 1312. The first ventilation hole 1311 is provided on the side of the housing case 13 opposite to the base 12 and is generally a kidney-shaped hole. The second ventilation hole 1312 extends from a position close to the first ventilation hole 1311 towards the lower edge of the housing case 13 and is generally an arc-shaped hole. A clamping block (not shown) is provided on the inner wall of the housing case 13 close to its lower edge. A clamping hole 1213 is provided at a position corresponding to the side of the first part 121 opposite to the second part 122. The housing case 13 is clamped to the base 12 through the matching connection of the clamping block and the corresponding clamping hole 1213. When assembled, the housing case 13 covers the outside of the corresponding plasma generating module 11, and the first ventilation hole 1311 aligns with the gap between adjacent two plasma generating components 111 from above the plasma generating assembly 111, and the second ventilation hole 1312 aligns with the gap between adjacent two plasma generating components 111 from the sides of the plasma generating assembly 111 respectively. In this way, when air flows through the plasma generating device 1, it can enter the housing case 13 through the openings 1214 at both ends to contact and be ionized by each plasma generating component 111. At the same time, it can also flow through the gap between adjacent two plasma generating components 111 via the first through-hole 11111 and the second through-hole 11121. This part of the air is wrapped by the high-voltage electrodes on both sides and is fully ionized, so that more plasma can be generated, and the air can be better sterilized and deodorized.

[0066] It should be noted that the first through-hole 11111 and the second through-hole 11121 can also be circular holes, oval holes or holes of other possible shapes such as polygonal holes. Of course, the ventilation structure 131 can also only include the first through-hole 11111 or the second through-hole 11121.

[0067] It should be noted that it can also be that the lower edge of the housing case 13 is provided with a clamping hole 1213, and the first part 121 is provided with a clamping block at the corresponding position. The housing case 13 can also be clamped to the base 12 through the matching connection of the clamping hole 1213 and the clamping block. Obviously, the housing case 13 and the base 12 can also be clamped in other ways. Of course, the housing case 13 can also be arranged on the base 12 by other possible ways such as screwing, bonding, plugging, etc.

[0068] Such as Figures 1 to 9As shown, the plasma generating device 1 further includes an indicator light (not shown), which can be an LED light strip. Through this indicator light, the operating state of the plasma generating device 1 can be displayed, and users can clearly know the actual operating condition of the plasma generating device through the indicator light. For example, when the indicator light shows red, it means that the plasma component is not operating; when the indicator light shows green, it means that the plasma component is operating normally, etc. Obviously, the indicator light can also be an LED lamp bead, etc. A limiting block 1225 is respectively provided corresponding between the mounting plate 1221 and each mounting table 1223 of the second part 122. An installation space is formed by surrounding between the limiting block 1225 and the mounting plate 1221, and the indicator light is arranged in the installation space in a screwed or clamped manner. An opening 1214 is provided at one end of the first part 121 along the length direction of the base 12. Through this opening 1214, the through holes 1212 and clamping holes 1213 provided on the first part 121, etc., users can clearly see the actual condition of the indicator light. That is to say, each plasma generating module 11 of the present application is respectively configured with an indicator light, and users can clearly know the specific operating state of each plasma generating module 11 through the display of each indicator light, which is convenient for users to understand the actual operating condition of the plasma generating device 1 in real time. It should be noted that it is also possible that the entire plasma generating device 1 is configured with an indicator light, or multiple plasma generating modules 11 are grouped, and each group of plasma generating modules 11 is jointly configured with an indicator light. Obviously, the plasma generating device 1 may not be configured with an indicator light.

[0069] The following will refer to Figures 1 to 9 、 Figure 14 to illustrate the possible implementation manners of installing the plasma generating device 1 of the present application on a wall-mounted air conditioner.

[0070] As Figures 1 to 9 、 Figure 14As shown, the wall-mounted air conditioner includes a housing 2. Inside the housing 2, there are a heat exchanger (not shown) and a blower (not shown). The housing 2 has an air inlet 21 and an air outlet 22. Under the action of the blower, indoor air enters the housing 2 through the air inlet 21, exchanges heat with the heat exchanger, and then returns to the indoor space through the air outlet 22. Inside the housing 2, three mounting structures are provided near the air outlet 22. For example, the mounting structure can be an adhesive layer, a mounting groove, a mounting hole, a buckle, or other possible structures. The three plasma generating devices 1 are respectively and matingly connected to the corresponding mounting structures through their bases 12, and are thus arranged near the air outlet 22. And when installed, the length direction of the plasma generating device 1 is parallel to the length direction of the housing 2. Among them, the base 12 can be matingly connected to the mounting structure by possible means such as screwing, clamping, or bonding. When the wall-mounted air conditioner is operating, the air sent out through the air outlet 22 will flow through the plasma generating device 1 and pass through the gaps between adjacent two plasma generating components 111, make full contact with the electrodes of the plasma generating components 111, and be ionized to generate more plasma, so as to fully perform sterilization and odor removal treatment on it. And because the energy of the plasma is relatively high, it can also diffuse into the indoor space along with the air flow, further perform sterilization and odor removal treatment on the air and the surfaces of objects in the indoor space, and obtain better sterilization and odor removal effects. The housing 2 is provided with a protective cover 23 on the outside of the plasma generating device 1. The protective cover 23 is composed of multiple pairs of arc-shaped structures, so as to form protection for the plasma generating device 1, and at the same time can also guide the air flow to the plasma generating device 1 and even between adjacent two plasma generating components 111, so that the air can be better ionized and better sterilization and odor removal effects can be obtained.

[0071] In summary, in the preferred technical solution of the present invention, by making the plasma generating device 1 include at least one plasma generating module 11, each plasma generating module 11 includes at least one plasma generating component 111, each plasma generating component 111 includes a first electrode 1111, a second electrode 1112 and an insulating dielectric layer 1113, and making the first electrode 1111 and the second electrode 1112 respectively adhere to both sides of the insulating dielectric layer 1113, a uniform electric field can be formed between the two electrodes, ionizing air to generate plasma, thereby realizing the sterilization and deodorization treatment of air. Moreover, the plasma can reach the space where the plasma generating device 1 is located along with the air flow, and further perform sterilization and deodorization treatment on the air and the surface of objects in the space. By making each plasma generating component 111 include two insulating dielectric layers 1113, making the size of the first electrode 1111 disposed between the two insulating dielectric layers 1113 smaller than the size of the second electrode 1112 disposed outside, and providing a first through hole 11111 and a second through hole 11121 on the first electrode 1111 and the second electrode 1112 respectively, in this way, it is equivalent to forming two spindle-shaped electric fields, and multiple discharge points are formed on the surfaces of the first electrode 1111 and the second electrode 1112, thereby effectively improving the ionization efficiency and being able to generate more plasma. Through the setting of the base 12, arranging multiple plasma generating components 111 of each plasma generating module 11 at intervals along the length direction of the base 12, and providing multiple plasma generating modules 11 on one base 12, through the wrapping of the air by two adjacent plasma generating components 111, a better sterilization and deodorization effect can be obtained.
