Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, specifically providing a plasma generating module, a plasma generating device, and an air conditioner. Background Technology

[0002] Air conditioners typically regulate indoor temperature by exchanging heat between indoor air and an indoor heat exchanger. Over time, this process accumulates bacteria, viruses, and particulate matter inside the air conditioner. When indoor air exchanges heat with the heat exchanger, it carries these bacteria, viruses, and particulate matter into the room, leading to a decline in indoor air quality and, in severe cases, harming people's health. Furthermore, since doors and windows are usually closed during air conditioner operation, unpleasant odors can develop indoors. Human activity indoors can also produce smoke, bathroom odors, and pet-related smells, all of which significantly impact comfort.

[0003] Therefore, people usually equip air conditioners with sterilization devices for sterilization and odor removal devices for odor removal, which is costly. In existing technologies, ozone and silver ion devices typically only perform sterilization, while activated carbon filters and photocatalytic devices typically only perform odor removal. Equipping both types of devices is costly and requires significant space. Furthermore, ozone itself is a harmful substance, requiring detoxification treatment before sterilization, leading to complex ozone equipment structures and high overall costs. Silver ion sterilization is less proactive; air can only be sterilized after passing through a silver ion device. Activated carbon filters have poor odor removal efficiency; to improve odor removal, multiple activated carbon filters are usually required, occupying a large space, creating air resistance, and needing regular replacement to prevent overflow and secondary pollution once saturated. Photocatalytic devices typically use a light source and a photocatalyst mesh, requiring a large space and creating air resistance, resulting in high costs. Negative ion devices can simultaneously sterilize and deodorize, but because negative ions carry a negative charge, they are easily adsorbed and neutralized by particulate matter (such as dust), have a short lifespan, and are consumed within a short distance, making it difficult for them to reach distant locations, thus limiting their sterilization and deodorization effects.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problems of low sterilization and odor removal efficiency, large space occupation, and high cost of existing sterilization and odor removal equipment.

[0006] In a first aspect, the present invention provides a plasma generating module, the plasma generating module (11) including at least one plasma generating component (111), the plasma generating component (111) including a first electrode (1111), a second electrode (1112) and an insulating dielectric layer (1113), the first electrode (1111) and the second electrode (1112) being respectively disposed on both sides of the insulating dielectric layer (1113), the first electrode (1111) and the second electrode (1112) being respectively attached to each other on both sides of the insulating dielectric layer (1113), and when the plasma generating component (111) is energized, the first electrode (1111) and the second electrode (1112) have opposite electrical properties.

[0007] In the preferred embodiment of the plasma generating module described above, a mounting position is formed on the side of the insulating dielectric layer (1113), and the first electrode (1111) and / or the second electrode (1112) are embedded in the mounting position.

[0008] In the preferred embodiment of the plasma generating module described above, the size of one of the first electrode (1111) and the second electrode (1112) is smaller than the size of the other.

[0009] In the preferred embodiment of the plasma generating module described above, 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] The second electrode (1112) is provided with a second through hole (11121), which penetrates the second electrode (1112) along the thickness direction of the second electrode (1112).

[0011] In the preferred embodiment of the plasma generating module described above, the plasma generating module (11) further includes a base (12), the plasma generating component (111) is fitted onto the base (12), and the plasma generating module (11) is mounted on the target component via the base (12).

[0012] In the preferred embodiment of the plasma generating module described above, the plasma generating module (11) further includes a cover (13), the cover (13) is disposed on the base (12), the cover (13) is provided with a ventilation structure (131), and the cover (13) covers the outside of the plasma generating module (11).

[0013] In the preferred embodiment of the plasma generating module described above, the plasma generating module (11) includes a plurality of plasma generating components (111), at least some of the plasma generating components (111) are spaced apart along the length direction of the base (12), and at least a portion of the ventilation structure (131) is aligned with the gap between two adjacent plasma generating components (111).

[0014] In the preferred embodiment of the plasma generating module described above, the plasma generating component (111) includes two insulating dielectric layers (1113), one of the first electrode (1111) and the second electrode (1112) is disposed between the two insulating dielectric layers (1113), and the other of the first electrode (1111) and the second electrode (1112) is disposed on the side portion of the two insulating dielectric layers (1113) facing away from each other.

[0015] In the technical solution of this utility model, the plasma generating module includes at least one plasma generating component. Each plasma generating component includes a first electrode, a second electrode, and an insulating dielectric layer. The first electrode and the second electrode are respectively disposed on both sides of the insulating dielectric layer, and the first electrode and the second electrode are respectively attached to each other with the insulating dielectric layer. When the plasma generating component is energized, the first electrode and the second electrode have opposite electrical properties. In this way, the two electrodes and the insulating dielectric layer are assembled together to form the plasma generating component. When the plasma generating component is energized, a uniform electric field can be formed between the two electrodes under the action of the insulating dielectric layer. When air flows through the plasma generating component, it ionizes oxygen and water molecules in the air to generate high-density, high-energy plasma, instead of producing harmful ozone. This plasma can quickly sterilize and deodorize the air, and because the plasma has high energy, it can diffuse with the airflow into the space where the plasma generating module is located, further sterilizing and deodorizing the air and objects in the space. Compared with negative ions, it can achieve better sterilization and deodorization effects.

[0016] Furthermore, the size of one of the first and second electrodes is smaller than that of the other. This allows a spindle-shaped electric field to be formed between the first and second electrodes when the plasma generation module is energized, effectively increasing the area covered by the electric field and improving the ionization efficiency.

[0017] Furthermore, 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 penetrate the first electrode and the second electrode along the thickness direction of the first electrode and the second electrode, respectively. When the plasma generating component is energized, a discharge point can be formed at each of the first through hole and the second through hole. This is equivalent to forming multiple discharge points on the two electrodes that can ionize air and generate plasma, which effectively improves the ionization efficiency and can generate more plasma.

[0018] Furthermore, the plasma generating assembly includes two insulating dielectric layers, with one of the first and second electrodes disposed between the two insulating dielectric layers, and the other of the first and second electrodes disposed on the sides of the two insulating dielectric layers facing away from each other. In this way, a plasma generating assembly is equivalent to having two pairs of first and second electrodes, capable of forming two electric fields, thereby ionizing and generating more plasma.

[0019] Secondly, this utility model also provides a plasma generating device, which includes the plasma generating module described in any of the foregoing embodiments.

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

[0022] It should be noted that this air conditioner has all the technical effects of the aforementioned plasma generating module or plasma generating device, which will not be repeated here. Attached Figure Description

[0040] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this utility model and are not intended to limit the scope of protection of this utility model. It should be noted that although the above description uses a plasma generating device installed in a wall-mounted air conditioner as an example, it can obviously also be installed in other types of air conditioners such as cabinet air conditioners, central air conditioners, ducted air conditioners, and window air conditioners, or in other types of air purification equipment such as air purifiers and sterilizers.

[0041] It should be noted that in the description of this utility model, terms such as "inner," "outer," "left," and "right," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] Currently, common ozone and silver ion devices typically only perform sterilization, while activated carbon filters and photocatalyst devices typically only remove odors. Both types of devices are required for both air sterilization and odor removal, and each device has low efficiency in both, occupies more space, and is more expensive. Negative ion devices, which can simultaneously sterilize and remove odors, generate negative ions that are easily adsorbed and neutralized, have a short lifespan, and struggle to reach distant locations, resulting in limited sterilization and odor removal effects. Therefore, the plasma generating module of this application includes at least one plasma generating component. Each plasma generating component includes a first electrode and a second electrode with opposite electrical polarities, and an insulating dielectric layer disposed between the first and second electrodes. This allows a uniform electric field to be formed between the first and second electrodes, ionizing the air to generate plasma, which then sterilizes and removes odors from the air.

[0044] The following is combined Figures 1 to 14 This paper describes possible implementations of the plasma generating device of this utility model.

[0045] like Figures 1 to 6As shown, the plasma generating device 1 includes at least one plasma generating module 11, which 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 approximately rectangular in shape. 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 sides of the insulating dielectric layer 1113, thus assembling the two electrodes and the insulating dielectric layer 1113 together to form the plasma generating component 111. When the plasma generating component 111 is energized, the first electrode 1111 and the second electrode 1112 have opposite electrical polarities, 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. Thus, when air flows through the plasma generating component 111, only oxygen and water molecules in the air are ionized to generate high-density, high-energy plasma, rather than harmful ozone. Plasma typically includes ionized clusters of positive and negative ions, electrons, and reactive oxygen species (ROS). Charged particles can attach to particles (such as dust) to increase their weight, causing them to settle or be captured by filters. Reactive oxygen species can decompose and transform harmful gases (VOCs) and inactivate microorganisms (bacteria, viruses, etc.) in the air, turning them into harmless or relatively stable substances. Therefore, this plasma can quickly sterilize and deodorize the air. Furthermore, the high energy of the plasma allows it to diffuse with the airflow into the space where the plasma generating device 1 is located, further sterilizing and deodorizing the air and objects within the space. Compared to negative ions, it achieves better sterilization and deodorization effects.

[0046] It should be noted that the plasma generating device 1 of this application is powered by an AC high-voltage power supply (e.g., a voltage of 2000V to 3000V). During operation, the electrical 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 one possible implementation, the first electrode 1111 and the second electrode 1112 can be made of metallic materials such as copper, stainless steel, or tungsten, and the insulating dielectric layer 1113 can be made of inorganic insulating materials with a high dielectric constant, such as ceramics or glass. Preferably, the first electrode 1111 and the second electrode 1112 are made of brass, and the insulating dielectric layer 1113 is made of ceramic.

[0048] like Figures 1 to 6As shown, each plasma generating assembly 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 disposed on the side of each insulating dielectric layer 1113 facing away from each other. Figure 6 As shown, the plasma generating assembly 111 consists of a second electrode 1112, an insulating dielectric layer 1113, a first electrode 1111, another insulating dielectric layer 1113, and the second electrode 1112 arranged sequentially from left to right. This effectively means that one plasma generating assembly 111 has two pairs of first electrodes 1111 and second electrodes 1112, forming two electric fields, thereby ionizing and generating more plasma. Furthermore, the size of the first electrode 1111 is smaller than the size of the second electrode 1112, thus forming a spindle-shaped electric field between the first electrode 1111 and the second electrode 1112. This electric field has a larger ionization area, achieving higher ionization efficiency and generating more plasma. Obviously, the second electrode 1112 can also be positioned between the two insulating dielectric layers 1113.

[0049] It should be noted that the size of the second electrode 1112 can also be smaller than the size 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 generating component 111 may also include only one insulating dielectric layer 1113. In this case, the plasma generating component 111 includes a first electrode 1111 and a second electrode 1112. Obviously, each plasma generating component 111 may also include three, four, five, or more insulating dielectric layers 1113. In this case, the first electrode 1111 and the second electrode 1112 are arranged alternately on the side of each insulating dielectric layer 1113. Taking a plasma generating component 111 including four insulating dielectric layers 1113 as an example, the plasma generating component 111 can be stacked in the following manner: first electrode 1111, insulating dielectric layer 1113, second electrode 1112, insulating dielectric layer 1113, first electrode 1111, insulating dielectric layer 1113, second electrode 1112, insulating dielectric layer 1113, and first electrode 1111.

[0051] For ease of explanation, the following description uses a plasma generating assembly 111 comprising a second electrode 1112, an insulating dielectric layer 1113, a first electrode 1111, an insulating dielectric layer 1113, and a second electrode 1112 arranged sequentially as an example, and combines this with... Figures 1 to 13 The possible implementations of the plasma generating device 1 of this utility model will be described in detail below.

[0052] like Figures 1 to 6As shown, the opposing sides of the two insulating dielectric layers 1113 are recessed inward to form a first groove 11131 serving as a mounting position. The first groove 11131 is approximately rectangular, and its bottom dimension is approximately equivalent to the dimension of the first electrode 1111. The outer sides of the two insulating dielectric layers 1113 are also recessed inward to form a second groove 11132 serving as a mounting position. The second groove 11132 is approximately rectangular, and its bottom dimension is approximately equivalent to the dimension of the second electrode 1112. Mounting holes 11133 are also provided on the two insulating dielectric layers 1113, located below the mounting positions. During assembly, fasteners (such as screws, bolts, etc.) are passed through two mounting holes 11133 to fasten the two insulating dielectric layers 1113 together. The two first grooves 11131 that are arranged opposite each other are fastened to form a mounting space. The first electrode 1111 is inserted into the mounting space. Then, the two second electrodes 1112 are respectively embedded in the second grooves 11132 on the outside of the two insulating dielectric layers 1113. 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 located on the outside of the plasma generating component 111, and the first electrode 1111 is located between the two insulating dielectric layers 1113. Furthermore, 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. This ensures a more uniform electric field between the first electrode 1111 and the second electrode 1112, preventing ozone generation due to tip discharge at the outer edges of the first electrode 1111 and the second electrode 1112. To ensure stable installation of the second electrode 1112 on the outside of the two insulating dielectric layers 1113, a limiting structure can be provided at the top of the second groove 11132. This limiting structure can be a circumferentially distributed structure or a pair of symmetrically arranged limiting plates, etc.

[0053] It should be noted that the first electrode 1111 and the second electrode 1112 can also be fixedly disposed on both sides of the insulating dielectric layer 1113 by means of bonding, snap-fitting, or plugging. Taking snap-fitting as an example, snap fasteners are provided on both sides of the insulating dielectric layer 1113, and snap holes 1213 are provided on the first electrode 1111 and the second electrode 1112 at corresponding positions. The first electrode 1111 and the second electrode 1112 are respectively disposed on both sides of the insulating dielectric layer 1113 through the matching of the snap fasteners and snap holes 1213. Without departing from the basic principles of this application, those skilled in the art can flexibly choose according to the specific application scenario, as long as the first electrode 1111 and the second electrode 1112 can be disposed on both sides of the insulating dielectric layer 1113.

[0054] like Figures 1 to 6As shown, the first electrode 1111 has multiple first through holes 11111, and the second electrode 1112 has multiple second through holes 11121. Both the first through holes 11111 and the second through holes 11121 are approximately circular holes, penetrating the first electrode 1111 and the second electrode 1112 along their respective thickness directions. The multiple first through holes 11111 and the multiple second through holes 11121 are arranged in an array on the first electrode 1111 and the second electrode 1112, forming a honeycomb-like structure. When the plasma generating component 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. This is equivalent to forming multiple discharge points on the two electrodes that can ionize air and generate plasma, effectively improving ionization efficiency and generating more plasma.

[0055] To gain a clearer understanding of the electric field distribution of the plasma generating component 111, the inventors of this application conducted a simulation in COMSOL. The specific results are available in [link to simulation]. Figures 10 to 13 COMSOL is a widely used multiphysics simulation software; its specific parameters and simulation process 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 component 111 is relatively uniform, and the potential distribution is also relatively uniform. Under the action of such an electric field, ionizing air will only produce plasma, and will not produce toxic ozone.

[0056] It should be noted that the first through hole 11111 and the second through hole 11121 can also be configured as other possible shapes such as polygons, rectangles, squares, and ellipses. Alternatively, only the first electrode 1111 may have the first through hole 11111, or only the second electrode 1112 may have the second through hole 11121. Obviously, neither the first electrode 1111 nor the second electrode 1112 may have through holes, and plasma may be generated solely through surface discharge of the first electrode 1111 and the second electrode 1112.

[0057] Continue to refer to Figures 1 to 6The plasma generating assembly 111 also includes an insulating member 1114. The size of the insulating member 1114 is smaller than that of the insulating dielectric layer 1113, and is approximately the same size and shape as the portion of the insulating dielectric layer 1113 except for the first groove 11131 and the second groove 11132. It has screw holes 11141. During assembly, the two insulating members 1114 are respectively placed on the outer sides of the two insulating dielectric layers 1113, with the screw holes 11141 aligned with the mounting holes 11133. Fasteners pass through one insulating member 1114, the two insulating dielectric layers 1113, and the other insulating member 1114 in sequence, fixing the two insulating members 1114 to the outer sides of the two insulating dielectric layers 1113. The insulating member 1114 ensures insulation between adjacent plasma generating assemblies 111 and also prevents the second electrode 1112 from falling away from the insulating dielectric layer 1113.

[0058] like Figures 1 to 9 As shown, the plasma generating device 1 also includes a base 12, which is generally a long strip structure, comprising a first part 121 and a second part 122. The first part 121 is generally an inverted cover-like structure, with four recessed slots 1211 formed on the inner wall of its circumferential sidewall. The four slots 1211 are grouped in pairs and symmetrically arranged on the inner side of the two long sidewalls of the circumferential sidewall, distributed along the length of the base 12. The second part 122 is generally a rectangular plate structure, with two mounting plates 1221 on its side facing the first part 121. The mounting plates 1221 extend circumferentially along the second part 122, and four locking blocks 1222 are provided at corresponding positions on the mounting plates 1221. The four locking blocks 1222 are grouped in pairs and symmetrically arranged on the outer side of the two long sides of the mounting plates 1221, distributed along the length of the base 12. The first part 121 and the second part 122 are fastened together by the matching connection of the slots 1211 and the corresponding locking blocks 1222. Obviously, it is also possible that a locking block 1222 is provided on the circumferential sidewall of the first part 121, and a locking groove 1211 or a locking hole 1213 is provided on the mounting plate 1221 of the second part 122. This application does not impose specific restrictions on the way the first part 121 and the second part 122 are engaged with each other, as long as the first part 121 and the second part 122 can be engaged with each other.

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

[0060] Continue to refer to Figures 1 to 9The plasma generating device 1 includes two plasma generating modules 11, each of which includes five plasma generating components 111. These five components are spaced apart along the length of the base 12. When assembled, there is a gap between adjacent plasma generating components 111. This allows the plasma generating device 1 to be fully ionized by the components surrounding it when air flows through it, thus enabling more thorough sterilization and deodorization of the air. Each insulating dielectric layer 1113 and insulating component 1114 has a locking space 113 on both sides of its lower end. A strip electrode 112 is disposed within each of the two locking spaces 113. The lower ends of the first electrode 1111 and the second electrode 1112 extend downwards, with clamping positions formed at their ends. All the first electrodes 1111 are clamped to the right-side strip electrode 112, and all the second electrodes 1112 are clamped to the left-side strip electrode 112. This connects the two types of electrodes of each plasma generating module 11 together, making it easier to control the plasma generating module 11 as a whole. Obviously, each plasma generating module 11 can also be equipped with its own base 12.

[0061] It should be noted that the plasma generating device 1 may include only one, or three, four, five or more plasma generating modules 11, and each plasma generating module 11 may include four, three, two or fewer, or six, seven, eight or more plasma generating components 111. In this embodiment, no limitation is made on the specific number of plasma generating modules 11 included in the plasma generating device 1, or the specific number of plasma generating components 111 included in each plasma generating module 11.

[0062] It should be noted that in this embodiment, the length direction of the base 12 is approximately as follows: Figure 7 The horizontal direction in the middle.

[0063] Continue to refer to Figures 1 to 9The second part 122, facing the side of the first part 121, is also provided with a mounting platform 1223. This mounting platform 1223 is located inside the mounting plate 1221 and includes two opposing strip blocks. The two strip blocks are parallel to each other and have a gap between them. Each of the two strip blocks has a strip-shaped protrusion 1224 on its side facing away from each other, extending along the length of the base 12. A through hole 1212 is formed on the side of the first part 121 opposite to the second part 122. This through hole 1212 is approximately rectangular. The lower ends of the two insulating dielectric layers 1113 form approximately arched recessed areas 11134. The distance between the opposite sides of these recessed areas 11134 is approximately equal to the distance between the two opposite sides of the two strip blocks. The two opposite sides are recessed away from each other to form locking positions 11135. During assembly, the lower ends of the two insulating dielectric layers 1113 are passed through the perforation 1212. Slight force is applied to slightly deform the two strip blocks towards each other, allowing the locking position 11135 to mate and connect with the strip protrusion 1224, thereby securing the plasma generating assembly 111 onto the base 12. Five plasma generating assemblies 111 are sequentially secured onto the base 12 along its length. When installed, there is a gap between adjacent plasma generating assemblies 111; that is, the five plasma generating assemblies 111 are spaced apart along the length of the base 12. It should be noted that the perforation 1212 can also be square, circular, elliptical, polygonal, or other possible shapes.

[0064] It should be noted that the mounting platform 1223 may also consist of a single strip block, the width of which is approximately equal to the distance between the opposite sides of the recessed area 11134 of the insulating dielectric layer 1113. Alternatively, a groove may be formed on the mounting platform 1223, with corresponding hooks formed inward on the opposite sides of the recessed area 11134, allowing the insulating dielectric layer 1113 to be engaged with the mounting platform 1223 through the matching of the hooks and the groove. Of course, the lower end of the insulating dielectric layer 1113 may not have a recessed area 11134. In this case, the outer edge of the lower end of the insulating dielectric layer 1113 may have hooks or latches formed outward, and the second part 122 may have corresponding holes 1213 or slots 1211. It should also be noted that the base 12 may not be formed by the first part 121 and the second part 122 interlocking, but rather as a single unit, with the plasma generating assembly 111 directly engaged with the base 12. Of course, the plasma generating component 111 can also be mounted on the base 12 by other possible methods such as plugging, bonding, or screwing.

[0065] like Figures 1 to 9As shown, the plasma generating device 1 also includes two housings 13. Each housing 13 has a ventilation structure 131. The housing 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 located on the side of the housing 13 opposite to the base 12 and is approximately waist-shaped. The second ventilation hole 1312 extends from near the first ventilation hole 1311 towards the lower edge of the housing 13 and is approximately arc-shaped. A locking block (not shown) is provided on the inner wall of the housing 13 near its lower edge. Locking holes 1213 are provided at corresponding positions on the sides of the first part 121 and the second part 122. The housing 13 is locked to the base 12 by the matching connection between the locking block and the corresponding locking hole 1213. When assembled, the housing 13 covers the outside of the corresponding plasma generating module 11, with the first ventilation hole 1311 aligned from above the plasma generating component 111 with the gap between each two adjacent plasma generating components 111, and the second ventilation hole 1312 aligned from the side of the plasma generating component 111 with the gap between each two adjacent plasma generating components 111. In this way, when air flows through the plasma generating device 1, it can enter the housing 13 through the openings 1214 at both ends, contact the plasma generating components 111, and be ionized. Simultaneously, it can also flow through the first through hole 11111 and the second through hole 11121 through the gap between two adjacent plasma generating components 111. This air is enveloped by the high-voltage electrodes on both sides and fully ionized, thereby generating more plasma and better sterilizing and deodorizing the air.

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

[0067] It should be noted that, alternatively, the lower edge of the cover 13 may have a locking hole 1213, and the first part 121 may have a locking block at the corresponding position. The cover 13 can also be snapped onto the base 12 through the matching connection of the locking hole 1213 and the locking block. Obviously, other methods can also be used to achieve the snap-fit ​​connection between the cover 13 and the base 12. Of course, the cover 13 can also be attached to the base 12 using other possible methods such as screwing, gluing, or plugging.

[0068] like Figures 1 to 9As shown, the plasma generator 1 also includes indicator lights (not shown). These indicator lights can be LED strips, which display the operating status of the plasma generator 1. Users can clearly understand the actual operating status of the plasma generator through the indicator lights. For example, a red indicator light indicates that the plasma component is not operating, while a green indicator light indicates that the plasma component is operating normally, and so on. Obviously, the indicator lights can also be LED beads, etc. The second part 122 has limit blocks 1225 respectively set between the mounting plate 1221 and each mounting stage 1223. The limit blocks 1225 and the mounting plate 1221 enclose an installation space, and the indicator lights are set in the installation space by screwing or snapping. The first part 121 has an opening 1214 at one end along the length of the base 12. Users can clearly see the actual status of the indicator lights through the opening 1214 and the through holes 1212 and snap holes 1213 provided on the first part 121. In other words, each plasma generating module 11 in this application is equipped with an indicator light. Users can clearly understand the specific operating status of each plasma generating module 11 through the display of each indicator light, facilitating real-time monitoring of the actual operation of the plasma generating device 1. It should be noted that the entire plasma generating device 1 can also be equipped with only one indicator light, or multiple plasma generating modules 11 can be grouped together, with each group sharing one indicator light. Obviously, the plasma generating device 1 can also be configured without indicator lights.

[0069] The following reference Figures 1 to 9 , Figure 14 This paper describes a possible implementation of the plasma generating device 1 of this application installed on a wall-mounted air conditioner.

[0070] like Figures 1 to 9 , Figure 14As shown, the wall-mounted air conditioner includes a casing 2, inside which a heat exchanger (not shown) and a fan (not shown) are installed. The casing 2 has an air inlet 21 and an air outlet 22. Under the action of the fan, indoor air enters the casing 2 through the air inlet 21 to exchange heat with the heat exchanger, and then returns to the indoor space through the air outlet 22. Three mounting structures are provided inside the casing 2 near the air outlet 22. For example, the mounting structures can be adhesive layers, mounting grooves, mounting holes, clips, or other possible structures. Three plasma generators 1 are respectively connected to their corresponding mounting structures via their bases 12, and are thus positioned near the air outlet 22. Furthermore, when installed, the length direction of the plasma generators 1 is parallel to the length direction of the casing 2. The bases 12 can be connected to the mounting structures by means of screws, clips, adhesives, or other possible methods. When the wall-mounted air conditioner is running, the air delivered through the air outlet 22 flows through the plasma generator 1 and passes through the gap between two adjacent plasma generating components 111, making full contact with the electrodes of the plasma generating component 111 and being ionized to generate a large amount of plasma, which thoroughly sterilizes and removes odors. Furthermore, due to the high energy of the plasma, it can also diffuse into the indoor space with the airflow, further sterilizing and removing odors from the air and surfaces of objects in the indoor space, achieving better sterilization and odor removal effects. The casing 2 has a protective cover 23 on the outside of the plasma generator 1. This cover 23 is composed of multiple pairs of arc-shaped structures to protect the plasma generator 1 and guide airflow to the plasma generator 1, and even between two adjacent plasma generating components 111, thereby better ionizing the air and achieving better sterilization and odor removal effects.

[0071] In summary, in the preferred embodiment of this utility model, by including at least one plasma generating module 11 in the plasma generating device 1, each plasma generating module 11 including at least one plasma generating component 111, each plasma generating component 111 including a first electrode 1111, a second electrode 1112 and an insulating dielectric layer 1113, and by attaching the first electrode 1111 and the second electrode 1112 to both sides of the insulating dielectric layer 1113 respectively, a uniform electric field can be formed between the two electrodes, ionizing the air to generate plasma, thereby achieving sterilization and deodorization of the air. Furthermore, the plasma can reach the space where the plasma generating device 1 is located with the airflow, and further sterilize and deodorize the air and object surfaces in the space. By including two insulating dielectric layers 1113 in each plasma generating component 111, 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 on the outer side, and providing a first through hole 11111 and a second through hole 11121 on the first electrode 1111 and the second electrode 1112 respectively, two spindle-shaped electric fields are formed, 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 generating more plasma. By setting up the base 12, arranging multiple plasma generating components 111 of each plasma generating module 11 at intervals along the length of the base 12, and setting multiple plasma generating modules 11 on one base 12, the air encapsulation by adjacent plasma generating components 111 achieves better sterilization and deodorization effects.

[0072] In addition, this utility model also provides a plasma generating device, which includes the plasma generating module described in any of the foregoing embodiments.

[0074] In addition, this utility model also provides an air conditioner equipped with the aforementioned plasma generating device.

[0075] It should be noted that this air conditioner has all the technical effects of the aforementioned plasma generating device, which will not be repeated here.
