Description

Technical Field

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

[0002] An air conditioner usually exchanges heat between indoor air and an indoor heat exchanger to adjust the temperature of the indoor space. After being used for a long time like this, a large amount of bacteria, viruses and particulate matters will accumulate inside. When the indoor air exchanges heat with the indoor heat exchanger, it will carry the bacteria, viruses and particulate matters 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, and these peculiar smells seriously affect the comfort.

[0003] Therefore, people usually configure a sterilization device on the air conditioner for sterilization treatment and configure an odor removal device for odor removal treatment, which has a high cost. In the prior art, ozone devices and silver ion devices usually can only perform sterilization treatment, and activated carbon filters and photocatalyst devices usually can only perform odor removal treatment. Configuring two devices at the same time has a high cost and requires a large amount 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. Photocatalyst devices usually use 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. Negative ion devices can perform both sterilization and odor removal treatments, but negative ions are extremely easy to be adsorbed and neutralized by particulate matters (such as dust, etc.) due to carrying negative charges, and have a short lifespan, and are consumed within a short distance range, and it is 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 in the prior art that the devices for sterilization and odor removal have low efficiency of sterilization and odor removal, require a large amount of space, and have a high cost.

[0006] In a first aspect, the present invention provides a plasma generating device, which includes at least one plasma generating part. The plasma generating part includes a first electrode, a second electrode, and an insulating dielectric layer. The first electrode is disposed outside the insulating dielectric layer, and the axis of the first electrode is parallel to the axis of the insulating dielectric layer. The second electrode penetrates through the insulating dielectric layer, and at least a part of the second electrode extends axially along the first electrode and the insulating dielectric layer.

[0007] In a preferred technical solution of the above plasma generating device, at least one recessed area is provided on the outer wall of the insulating dielectric layer, and at least a part of the recessed area extends circumferentially along the insulating dielectric layer.

[0008] In a preferred technical solution of the above plasma generating device, the first electrode includes a main body part and a mounting part that are electrically connected to each other. The main body part is arranged in a cylindrical structure and is provided with ventilation holes. The main body part extends axially along the insulating dielectric layer, and the mounting part is disposed at an axial end of the main body part.

[0009] In a preferred technical solution of the above plasma generating device, at least one docking structure is provided at a position near the outer edge of the mounting part, and at least one protruding end extends outward from an end of the main body part. The protruding end is adapted to the docking structure.

[0010] In a preferred technical solution of the above plasma generating device, the insulating dielectric layer is provided with a through hole that axially penetrates the insulating dielectric layer, and the second electrode penetrates through the through hole.

[0011] In a preferred technical solution of the above plasma generating device, the plasma generating device further includes a base. At least one mounting position is formed on a side of the base close to the plasma generating part. The plasma generating part is disposed in the mounting position, and when assembled, at least a part of the plasma generating part is embedded in the mounting position.

[0012] In a preferred technical solution of the above plasma generating device, a plurality of mounting positions are provided on the base, and at least a part of the plurality of mounting positions are arranged along the length direction of the base. When assembled, the axis of the plasma generating part extends along the length direction of the base.

[0013] In a preferred technical solution of the above plasma generating device, the first electrode further includes an electrical connection end that extends outward from the mounting part. When assembled, at least a part of the electrical connection end extends into the base.

[0014] In the technical solution of the present invention, the plasma generating device includes at least one plasma generating part, and the plasma generating part includes a first electrode, a second electrode and an insulating dielectric layer. The first electrode is disposed on the first side of the insulating dielectric layer, and the axis of the first electrode is parallel to the axis of the insulating dielectric layer. The second electrode penetrates through the second side of the insulating dielectric layer, and at least a part of the second electrode extends axially along the first electrode and the insulating dielectric layer. That is to say, the first electrode, the second electrode and the insulating dielectric layer of the plasma generating part all extend in the same direction. In this way, when the plasma generating device is powered on, a uniform electric field is formed between the two electrodes under the blocking of the insulating dielectric layer. No matter from which direction the air flows through the plasma generating device, it can be ionized by the electric field to generate high-density and high-energy plasma, rather than generating harmful ozone. The generated plasma can quickly sterilize and remove odors from the air, and the energy of the plasma is relatively high, and it can diffuse into the space where the plasma generating device is located along with the air flow, further sterilizing and removing odors from the air and objects in the space. Compared with negative ions, better sterilization and odor removal effects can be obtained.

[0015] Further, at least one recessed area is provided on the outer wall of the insulating dielectric layer, and at least a part of the recessed area extends circumferentially along the insulating dielectric layer. In this way, at least one flow passage is formed between the first electrode and the insulating dielectric layer. When the air flows through the plasma generating device, at least a part of the air will enter the flow passage, fully contact with the first electrode, and be ionized to generate more plasma.

[0016] Further, the first electrode includes a main body part and a mounting part that are electrically connected to each other. The main body part is arranged in a cylindrical structure and extends axially along the insulating dielectric layer. The mounting part is arranged at the end of the main body part, and ventilation holes are provided on the main body part. When assembled, there is at least a gap between the inner wall of the main body part and the recessed area. When the plasma generating device is powered on, an electric field can be formed between the first electrode and the second electrode, and an electric field can also be generated at the ventilation holes. In this way, when the air flows through the plasma generating device, at least a part of the air will enter the flow passage between the main body part and the recessed area through the ventilation holes, or be discharged from the flow passage between the main body part and the recessed area through the ventilation holes. During this process, this part of the air can be fully ionized by the electric field at the ventilation holes and between the first electrode and the second electrode to generate more plasma.

[0017] Further, the insulating dielectric layer is provided with a through hole that penetrates the insulating dielectric layer along the axial direction thereof, and the second electrode is inserted through the through hole. That is to say, the second electrode also extends along the axial direction of the insulating dielectric layer, and its axis is parallel to the axes of the first electrode and the insulating dielectric layer. In this way, the electric field generated between the second electrode and the first electrode can be made more uniform.

[0018] In a second aspect, the present invention also provides an air conditioner configured with the plasma generating device according to any one of the foregoing solutions.

[0019] In a preferred technical solution of the above air conditioner, the air conditioner includes a housing having an air outlet, and the plasma generating device is disposed at a position close to the air outlet and extends along the length direction of the air outlet.

[0020] It should be noted that the air conditioner has all the technical effects of the foregoing plasma generating device, which will not be elaborated herein. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] 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 air conditioners, or other types of air purification equipment such as air purifiers and disinfection machines.

[0031] It should be noted that in the description of the present invention, the terms indicating directions or positional relationships such as "down", "inside", "outside", "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, so it cannot be understood as a limitation of the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] 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.

[0033] 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. Moreover, the sterilization and odor removal efficiency of each device is relatively low, which requires a large amount of space and incurs high costs. The negative ions generated by negative ion devices that can perform sterilization and odor removal treatment simultaneously are extremely easy to be adsorbed and neutralized, have a short lifespan, and it is very difficult to reach positions far away from them, resulting in limited sterilization and odor removal effects. Therefore, the plasma generation part of the plasma generation device of the present application includes an insulating dielectric layer, a first electrode and a second electrode extending axially along the insulating dielectric layer, with the first electrode disposed on the first side of the insulating dielectric layer and the second electrode passing through the insulating dielectric layer. Thus, no matter which direction the air flows through the plasma generation device, it can be ionized by the uniform electric field formed between the first electrode and the second electrode to generate plasma, and the air is sterilized and deodorized through the plasma.

[0034] The following will Figures 1 to 5 describe the possible implementation manners of the plasma generation device of the present invention.

[0035] As Figures 1 to 5As shown, the plasma generating device 1 includes at least one plasma generating part 11, and the plasma generating part 11 includes a first electrode 111, a second electrode 112 and an insulating dielectric layer 113. The first electrode 111 is disposed on the first side of the insulating dielectric layer 113 (substantially the outer side of the insulating dielectric layer 113), and the axis of the first electrode 111 is parallel to the axis of the insulating dielectric layer 113. The second electrode 112 penetrates through the second side of the insulating dielectric layer 113 (substantially the inner side of the insulating dielectric layer 113), and at least a part of the second electrode 112 extends along the axial direction of the first electrode 111 and the insulating dielectric layer 113. That is to say, the first electrode 111, the second electrode 112 and the insulating dielectric layer 113 of the plasma generating part 11 all extend in the same direction. The first electrode 111 and the second electrode 112 are respectively electrically connected to a power supply, and the electrical properties of the two electrodes are opposite after the plasma generating device 1 is powered on. In this way, a potential difference can be formed between the two electrodes, and then a high-voltage electric field can be formed. Under the blocking action of the insulating dielectric layer 113, the electric field formed between the two electrodes can be made more uniform. The uniform electric field extends along the axial direction of the insulating dielectric layer 113 and at least partially surrounds the circumferential direction of the insulating dielectric layer 113. In this way, no matter from which direction the air flows through the plasma generating device 1, it can be ionized by the electric field distributed along the circumferential direction of the insulating dielectric layer 113 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, reactive oxygen species (ROS), etc. Charged particles can attach to particles (such as dust) to increase their weight and cause them to settle or be captured by a filter. Reactive oxygen species can decompose and transform harmful gases (such as VOCs) and inactivate microorganisms (such as bacteria and viruses) in the air, turning them into harmless or relatively stable substances. It can be seen that the plasma generated by using the plasma generating device 1 of the present invention can quickly sterilize and remove odors from the air, 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 removing odors from the air and objects in the space. Compared with negative ions, better sterilization and odor removal effects can be obtained.

[0036] It should be noted that in this embodiment, the axial direction of the insulating dielectric layer 113 is substantially Figure 1 the horizontal direction in

[0037] 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 to 3000V, etc.). During operation, the electrical polarities of the first electrode 111 and the second electrode 112 are always opposite. Obviously, a high-voltage battery pack can also be used to power the plasma generating device 1. Among them, the high-voltage battery pack can process the input DC power supply or AC power supply through an EMI processing circuit and a lightning protection circuit, and then raise the low voltage to an AC high voltage through circuits such as a pulse oscillation circuit, overvoltage current limiting, and high-low voltage isolation. The AC high voltage has no positive and negative poles. After the first electrode 111 and the second electrode 112 are electrically connected to the high-voltage battery pack, their electrical polarities are opposite. When the first electrode 111 is the positive pole, the second electrode 112 is the negative pole; when the second electrode 112 is the positive pole, the first electrode 111 is the negative pole. The first electrode 111 and the second electrode 112 intermittently switch between the positive and negative poles.

[0038] In a possible implementation manner, the first electrode 111 and the second electrode 112 can be prepared from metal materials such as copper, stainless steel, and tungsten, and the insulating dielectric layer 113 can be prepared from inorganic insulating materials with a relatively large dielectric constant such as ceramics and glass.

[0039] Preferably, the first electrode 111 is made of brass, the second electrode 112 is made of stainless steel, and the insulating dielectric layer 113 is made of ceramics. In this way, the first electrode 111 can discharge continuously and stably, the second electrode 112 has a high hardness, is not easily oxidized during discharge, and can be used for a long time. The insulating dielectric layer 113 has a relatively high dielectric constant, which can ensure effective insulation between the first electrode 111 and the second electrode 112, thus ensuring the service life of the plasma generating part 11.

[0040] Such as Figure 2 、 Figure 3 、 Figure 5As shown, the insulating dielectric layer 113 is generally a cylindrical structure, and two recessed regions 1131 are provided on its outer wall. Each recessed region 1131 extends along the circumferential direction of the insulating dielectric layer 113 to form a generally annular recessed region 1131, and the two recessed regions 1131 are arranged in sequence along the axial direction of the insulating dielectric layer 113. The first electrode 111 includes a main body portion 1111 and a mounting portion 1112 that are electrically connected to each other. The main body portion 1111 is arranged as a cylindrical structure and extends along the axial direction of the insulating dielectric layer 113. The cylindrical structure can be directly integrally cast from brass, or can be prepared from brass into two rectangles, and then bent so that the side edges of the two rectangles are butt-jointed with each other to enclose and form. A plurality of ventilation holes 1113 are provided on the main body portion 1111. The ventilation holes 1113 are circular holes, and the plurality of circular holes are uniformly arranged in an array along the circumferential direction of the main body portion 1111, and the distances between adjacent two ventilation holes 1113 are all equal. When the plasma generating device 1 is energized, an electric field can be formed between the first electrode 111 and the second electrode 112, and at the same time, an electric field can also be generated at each ventilation hole 1113, and the electric fields at each ventilation hole 1113 are relatively uniform. The mounting portion 1112 is generally annular, and a plurality of first notches serving as docking structures 11121 are provided at positions close to the outer edge. The plurality of first notches are uniformly distributed along the circumferential direction of the mounting portion 1112. Both ends of the insulating dielectric layer 113 along its axial direction (roughly the Figure 2 left and right ends of the insulating dielectric layer 113 shown in the figure) are respectively provided with annular mounting plates 1132. The outer diameter of the annular mounting plate 1132 is larger than the outer diameter of the insulating dielectric layer 113 and is roughly equivalent to the outer diameter of the mounting portion 1112, and the center of the annular mounting plate 1132 is located on the axis of the insulating dielectric layer 113. One end of the insulating dielectric layer 113 (roughly the Figure 2 right end of the insulating dielectric layer 113 shown in the figure) forms an annular mounting groove at a position close to the annular mounting plate 1132. A clamping position 1133 is formed between the annular mounting groove and the annular mounting plate 1132, and the mounting portion 1112 is clamped in the clamping position 1133. The end of the main body portion 1111 close to the mounting portion 1112 (roughly the Figure 2At the right end of the main body 1111 shown in the figure, a plurality of protruding ends 11111 extend outward. The protruding ends 11111 extend axially outward along the main body 1111 and are substantially arc-shaped pieces. The protruding ends 11111 correspond to the first notches one by one. When assembled, each protruding end 11111 is respectively snapped into the corresponding first notch. The main body 1111 is coaxially arranged with the insulating dielectric layer 113, and the outer edge of the main body 1111 is flush with the outer edges of the mounting portion 1112 and the annular mounting plate 1132. In this way, through the adaptation of the annular mounting plate 1132, the mounting portion 1112, and the protruding ends 11111 and the first notches, the first electrode 111 is fixedly arranged on the first side of the insulating dielectric layer 113 (substantially the outer side of the insulating dielectric layer 113). When assembled, there is at least a gap between the inner wall of the first electrode 111 and the recessed area 1131 of the insulating dielectric layer 113, so that a flow channel is formed at least at one place between the first electrode 111 and the insulating dielectric layer 113. When air flows through the plasma generating device 1, at least a part of the air enters the flow channel through the ventilation holes 1113 or is discharged from the flow channel through the ventilation holes 1113. When in the flow channel and during the process of entering and leaving the flow channel, the air can be fully ionized by the electric field between the first electrode 111 and the second electrode 112 and the electric field at the ventilation holes 1113, thereby generating more plasma. Obviously, there may also be a gap between the inner wall of the first electrode 111 and the non-recessed area 1131 of the insulating dielectric layer 113, so as to more conveniently allow air to pass through the electric field formed between the first electrode 111 and the second electrode 112, and then be better ionized to generate plasma.

[0041] It should be noted that the recessed area 1131 may not be set as a ring shape, but may be other possible shapes such as arc-shaped, curved, wavy, etc. Obviously, only one recessed area 1131 may be provided on the outer wall of the insulating dielectric layer 113, or three, four or more recessed areas 1131 may be provided. Without departing from the basic principle of the present application, those skilled in the art can flexibly determine the specific shape and specific number of the recessed area 1131 according to the specific application scenario, as long as a flow channel can be formed between the inner wall of the first electrode 111 and the insulating dielectric layer 113.

[0042] It should be noted that the docking structure 11121 may not be set as the first notch, but may be a hole in a rectangular, square, fan-shaped or other possible shape near the outer edge of the mounting portion 1112, or a mounting groove on the mounting portion 1112 whose projection on the mounting portion 1112 is in a rectangular, square, fan-shaped or other possible shape, as long as it can be adapted to the protruding ends 11111.

[0043] It should be noted that the annular mounting plate 1132 can be prepared integrally with the insulating dielectric layer 113, or can be arranged at both ends of the insulating dielectric layer 113 by means of screwing, clamping, bonding, etc. Among them, the preparation material of the annular mounting plate 1132 can be the same as that of the insulating dielectric layer 113, or can be made of an insulating material different from that of the insulating dielectric layer 113. Of course, the outer diameter of the annular mounting plate 1132 can also be smaller than or larger than the outer diameter of the mounting portion 1112.

[0044] It should be noted that the first electrode 111 can also only include the main body portion 1111. In this case, the first electrode 111 can be arranged on the outer side of the insulating dielectric layer 113 by means of embedding, clamping, bonding or other possible means. Taking the first electrode 111 clamped on the outer side of the insulating dielectric layer 113 as an example, the first electrode 111 is provided with buckles, and the insulating dielectric layer 113 is provided with a plurality of card slots at corresponding positions. The first electrode 111 is clamped on the outer side of the insulating dielectric layer 113 through the matching connection of the buckles and the card slots.

[0045] As Figure 2 , Figure 3 , Figure 5 shown, the insulating dielectric layer 113 is provided with a through hole 1134. The through hole 1134 penetrates the insulating dielectric layer 113 along the axial direction of the insulating dielectric layer 113. The cross section of the through hole 1134 is approximately circular, and its center is located on the axis of the insulating dielectric layer 113. The second electrode 112 is set as a stainless steel rod with a circular cross section. The diameter of the through hole 1134 is slightly larger than the diameter of the stainless steel rod. The second electrode 112 is inserted into the through hole 1134, so that the second electrode 112 is arranged on the second side of the insulating dielectric layer 113. When assembled, the first electrode 111, the second electrode 112 and the insulating dielectric layer 113 are coaxially arranged. In this way, the distance between the first electrode 111 and the second electrode 112 is equal everywhere. When the plasma generating device 1 is powered on, all the potential differences between the first electrode 111 and the second electrode 112 are exactly the same, so that a more uniform electric field can be generated between the two. Obviously, the cross section of the through hole 1134 can also be set as an ellipse, a polygon, a square or other possible shapes, as long as it allows the stainless steel rod to pass through.

[0046] As Figures 1 to 5As shown, the plasma generating device 1 further includes a base 12, which is generally in a long strip shape and includes a first part 121 and a second part 122. The first part 121 is generally in an inverted cover shape, and six card slots 1211 are formed by the inward depression of the inner wall of its circumferential side wall. The six card slots 1211 are divided into three groups, symmetrically arranged on the inner sides of the two long side walls of the circumferential side wall, and the three card slots 1211 on each side are arranged in sequence along the length direction of the base 12. The second part 122 is generally in a rectangular plate shape, and a mounting plate 1221 is provided on the side facing the first part 121. The mounting plate 1221 extends along the circumference of the second part 122, and six blocks 1222 are provided at corresponding positions on the mounting plate 1221. The six blocks 1222 are divided into three groups, symmetrically arranged on the outer sides of the two long sides of the mounting plate 1221, and the three blocks 1222 on each side are arranged in sequence along the length direction of the base 12. The first part 121 and the second part 122 are buckled together through the matching connection of the card slots 1211 and the corresponding blocks 1222. Obviously, it is also possible to provide blocks 1222 on the circumferential side wall of the first part 121 and card slots 1211 or card holes 1217 on the mounting plate 1221 of the second part 122. The present application does not specifically limit the way the first part 121 and the second part 122 are buckled together, as long as the first part 121 and the second part 122 can be buckled together.

[0047] Continue to refer to Figures 1 to 5 , two openings 1212 are formed on the opposite sides (generally the top side of the first part 121 shown in Figure 3 ) of the first part 121 and the second part 122. The two openings 1212 are arranged along the length direction of the base 12. The openings 1212 are generally rectangular, and the long side edges thereof extend along the length direction of the base 12. Moreover, the size of the long side edge of the opening 1212 is generally equivalent to the size of the first electrode 111 along its axial direction. A mounting platform 1213 is further provided on the top side of the first part 121. Two mounting platforms 1213 are respectively provided near each opening 1212, and the two mounting platforms 1213 are respectively located on the left and right sides of the corresponding opening 1212. Each mounting platform 1213 extends along the width direction of the opening 1212, and two mounting columns 1214 are provided on each mounting platform 1213. The mounting columns 1214 extend along the direction perpendicular to the top side of the first part 121, and the two mounting columns 1214 are arranged along the width direction of the opening 1212. A first through hole 1215 is provided between the two mounting columns 1214, and the first through hole 1215 penetrates the top side of the first part 121. In this way, the opening 1212 and the mounting platform 1213 constitute an installation position for arranging the plasma generating part 11.

[0048] Each plasma generating unit 11 further includes two strip-shaped mounting pieces 114. Two mounting holes 1141 are formed on each strip-shaped mounting piece 114, and a second through hole 1142 is provided between the two mounting holes 1141. Both ends of the second electrode 112 extend out of the insulating dielectric layer 113 along its axial direction, and slot holes 1121 are respectively provided at both ends thereof. The slot holes 1121 are formed by inward depression at the ends of the second electrode 112. Third through holes 1122 are respectively provided at positions of the second electrode 112 near both ends. The third through holes 1122 penetrate the second electrode 112 and the slot holes 1121 along the radial direction of the second electrode 112. During assembly, the lower part of the plasma generating unit 11 is inserted into the corresponding opening 1212, the strip-shaped mounting pieces 114 are respectively inserted into the corresponding slot holes 1121, the second through holes 1142 are respectively aligned with the corresponding third through holes 1122, and then the mounting holes 1141 on the strip-shaped mounting pieces 114 are respectively aligned with the corresponding mounting posts 1214 to be adapted to the corresponding mounting posts 1214, so as to realize the assembly of the second electrode 112 and the base 12, and thus the plasma generating unit 11 can be stably arranged on the base 12. When assembled, at least a part of the plasma generating unit 11 passes through the opening 1212 and extends into the base 12, so that at least a part of the plasma generating unit 11 is embedded in the installation position, and when assembled, the axis of the plasma generating unit 11 extends along the length direction of the base 12. Moreover, the first through hole 1215, the second through hole 1142 and the third through hole 1122 are aligned with each other, which is convenient for the electrical connector connected to the power supply to pass through these through holes and be electrically connected to the second electrode 112, thereby ensuring the power supply of the second electrode 112.

[0049] It should be noted that the opening 1212 can also be replaced by a groove formed by inward depression from the top side of the first part 121, and the mounting table 1213 can be replaced by a downwardly depressed clamping groove. Correspondingly, a clamping buckle or a clamping block is correspondingly provided on the strip-shaped mounting piece 114, and the fixed installation of the second electrode 112 can also be realized through the adaptation of the clamping buckle or the clamping block and the clamping groove. Obviously, the installation position may not be composed of the opening 1212 and the mounting table 1213, and may also only include the opening 1212 or the mounting table 1213. Taking the installation position only including the mounting table 1213 as an example, the height of the mounting table 1213 is approximately equal to the radius of the first electrode 111. Through the adaptation of the mounting holes 1141 on the strip-shaped mounting piece 114 and the mounting posts 1214 on the mounting table 1213, the plasma generating unit 11 can also be fixed on the base 12. Without departing from the basic principle of the present application, those skilled in the art can flexibly select the specific composition mode of the installation position according to the specific application scenario as long as the installation of the plasma generating unit 11 can be realized.

[0050] It should be noted that the long side of the opening 1212 may not extend along the length direction of the base 12, but may form an angle with the length direction of the base 12. Of course, only one mounting position may be provided on the base 12, or three, four or more mounting positions may be provided. When multiple mounting positions are provided on the base 12, the multiple mounting positions may not be arranged along the length direction of the base 12, and the connection line between the multiple mounting positions may also form an angle with the length direction of the base 12. On the premise of not deviating from the basic principle of this application, those skilled in the art can flexibly select the number of mounting positions and the specific extension mode of the mounting positions according to the specific application scenario, as long as the installation of the plasma generating part 11 can be realized.

[0051] It should be noted that in this embodiment, the length direction of the base 12 is approximately Figure 2 the horizontal direction in

[0052] As Figures 1 to 3 shown, the first electrode 111 further includes an electrical connection end 1114, which extends outward from the outer edge of the mounting portion 1112. It is generally a strip-shaped structure, and the end away from the mounting portion 1112 is rounded. When assembled, the electrical connection end 1114 extends downward from the first electrode 111, passes through the opening 1212 provided in the first part 121 and extends into the base 12, and then is electrically connected to the power supply through an electrical connector to ensure the power supply of the first electrode 111. Obviously, the first electrode 111 may not be provided with the strip-shaped electrical connection end 1114, but a connection portion may be formed on the main body portion 1111 or the mounting portion 1112, and the electrical connector electrically connected to the power supply passes through the slot and is electrically connected to this connection portion, so that the electrical connection between the first electrode 111 and the power supply can also be realized.

[0053] As Figures 1 to 4As shown, the plasma generating device 1 further includes a housing 13. A ventilation structure 131 is provided on the housing 13. The housing 13 is generally an arched structure with openings 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 13 opposite to the base 12 and is generally a kidney-shaped hole. The second ventilation hole 1312 extends from a position near the first ventilation hole 1311 towards the lower edge of the housing 13 and is generally an arc-shaped hole. A buckle 132 is provided on the inner wall of the housing 13 near its lower edge. A clamping hole 1217 is provided at a position corresponding to the opposite side of the first part 121 and the second part 122. The housing 13 is clamped to the base 12 through the matching connection of the buckle 132 and the corresponding clamping hole 1217. When assembled, the housing 13 covers the outside of the plasma generating part 11. In this way, when air flows through the plasma generating device 1, it can enter the housing 13 through the openings 1212 at both ends, the first ventilation hole 1311, and the second ventilation hole 1312, contact the plasma generating part 11, and be ionized, so that more plasma can be generated, and the air can be better sterilized and deodorized.

[0054] It should be noted that the first ventilation hole 1311 and the second ventilation hole 1312 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 ventilation hole 1311 or the second ventilation hole 1312.

[0055] It should be noted that it can also be that a clamping hole 1217 is provided at the lower edge of the housing 13, and a buckle 132 is provided at the corresponding position of the first part 121. The housing 13 can also be clamped to the base 12 through the matching connection of the clamping hole 1217 and the buckle 132. Obviously, the housing 13 and the base 12 can also be clamped in other ways. Of course, the housing 13 can also be arranged on the base 12 by other possible ways such as screwing, bonding, and plugging.

[0056] Continue to refer to Figure 3, the plasma generating device 1 further includes an indicator light 14, which can be an LED light strip. Through this indicator light 14, the operating state of the plasma generating device 1 can be displayed. For example, when the indicator light 14 shows red, it means that the plasma component is not operating; when the indicator light 14 shows green, it means that the plasma component is operating normally, etc. Obviously, the indicator light 14 can also be an LED lamp bead, etc. The second part 122 is further provided with a limiting block 1223 near the mounting plate 1221. An installation space is formed by enclosing between the limiting block 1223 and the mounting plate 1221. The indicator light 14 is arranged in the installation space in a screwed or clamped manner. One end of the first part 121 along the length direction of the base 12 is provided with a second notch 1216. Through this second notch 1216, the perforations and clamping holes 1217 provided on the first part 121, etc., the user can clearly see the actual condition of the indicator light 14. That is to say, each plasma generating part 11 of the present application is respectively provided with an indicator light 14. Through the display of each indicator light 14, the user can clearly know the specific operating state of each plasma generating part 11, which is convenient for the user to understand the actual situation of the operation 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 provided with one indicator light 14, or multiple plasma generating parts 11 are grouped, and each group of plasma generating parts 11 is jointly provided with one indicator light 14. Obviously, the plasma generating device 1 can also be not provided with an indicator light 14.

[0057] The following will be described with reference to Figures 1 to 6 to illustrate the possible implementation manners of installing the plasma generating device 1 of the present application on a wall-mounted air conditioner.

[0058] As Figures 1 to 6As shown in the figure, 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. An installation structure is provided inside the housing 2 near the air outlet 22. The plasma generating device 1 is arranged near the air outlet 22 through the matching connection of the base 12 with the installation structure. Among them, the base 12 can be matched and connected with the installation structure by possible means such as screwing, clamping, bonding, etc. When installed, the plasma generating device 1 extends along the length direction of the air outlet 22. That is to say, the axis of the plasma generating part 11 is parallel to the length direction of the air outlet 22. In this way, when the wall-mounted air conditioner operates, the air sent out through the air outlet 22 will flow through the plasma generating device 1 along the radial direction of the plasma generating part 11, which is beneficial for the air to enter the flow channel between the first electrode 111 and the insulating dielectric layer 113 through the ventilation holes 1113 on the first electrode 111. This part of the air can be fully ionized by the electric field between the first electrode 111 and the second electrode 112 and the electric field at the ventilation holes 1113, generating more plasma and fully performing sterilization and odor removal treatment on it. At the same time, due to the high energy of the plasma, it can also diffuse into the indoor space along with the air flow, further performing sterilization and odor removal treatment on the air and the surface of objects in the indoor space, obtaining a better sterilization and odor removal effect. A protective cover 23 is provided outside the plasma generating device 11 on the housing 2. The protective cover 23 is composed of multiple pairs of arc-shaped structures to form protection for the plasma generating device 11, and at the same time, it can also guide the air flow to the plasma generating device 11 and even between two adjacent plasma generating components 111, so as to better ionize the air and obtain a better sterilization and odor removal effect.

[0059] In summary, in the preferred technical solution of the present invention, by making the plasma generating device 1 include at least one plasma generating part 11, each plasma generating part 11 includes a first electrode 111, a second electrode 112 and an insulating dielectric layer 113, and making the axes of the first electrode 111 and the insulating dielectric layer 113 parallel to each other, and making the second electrode 112 penetrate through the insulating dielectric layer 113, a uniform electric field can be formed between the two electrodes, ionizing air to generate plasma, and further realizing the sterilization and deodorization treatment of air. And 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 providing at least one recessed area 1131 on the outer wall of the insulating dielectric layer 113 and providing ventilation holes 1113 on the main body part 1111 of the first electrode 111, a flow channel can be formed between the first electrode 111 and the insulating dielectric layer 113. During the process of air entering and leaving this flow channel, the air can be ionized more thoroughly, so that the sterilization and deodorization treatment of air can be better performed. By making the second electrode 112 penetrate through the through hole 1134 extending along the axial direction of the insulating dielectric layer 113, the first electrode 111, the second electrode 112 and the insulating dielectric layer 113 can be coaxially arranged, so that a more uniform electric field can be generated. By providing at least one installation position on the base 12, making at least a part of the plasma generating part 11 embedded in the installation position, and arranging a plurality of installation positions along the length direction of the base 12, the plasma generating part 11 can be stably arranged on the base 12, and through the wrapping of the air by two adjacent plasma generating parts 11, a better sterilization and deodorization effect can be obtained.

[0060] In addition, the present invention also provides an air conditioner, which is configured with the aforementioned plasma generating device 1.

[0061] In the preferred technical solution of the aforementioned air conditioner, the air conditioner includes a housing 2, the housing 2 has an air outlet 22, the plasma generating device 1 is arranged at a position close to the air outlet 22, and the plasma generating device 1 extends along the length direction of the air outlet.

[0062] It should be noted that the air conditioner has all the technical effects of the aforementioned plasma generating device 1, which will not be elaborated here.

[0063] Of course, the above replaceable embodiments, as well as between the replaceable embodiments and the preferred embodiments, can also be used in cross combination to combine new embodiments to be applicable to more specific application scenarios.

[0064] In addition, those skilled in the art can understand that although some of the embodiments described herein include certain features included in other embodiments rather than other features, the combination of features of different embodiments means that it is within the scope of the present invention and forms different embodiments.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
