Description

Technical Field

[0001] This utility model relates to the field of air treatment technology, specifically providing an ion generator and an air conditioner having the ion generator. Background Technology

[0002] Air conditioners typically regulate indoor temperature by exchanging heat between indoor air and an indoor heat exchanger. Over time, however, a large amount of bacteria, viruses, and particulate matter accumulates inside the air conditioner. When indoor air exchanges heat with the heat exchanger, it carries these bacteria, viruses, and particulate matter from the air conditioner into the indoor space, leading to a decline in indoor air quality and, in severe cases, endangering people's health.

[0003] Therefore, air conditioners are typically equipped with purification devices for sterilization and dust removal. These devices usually include ozone generators, silver ion generators, activated carbon filters, photocatalyst devices, and negative ion generators. However, ozone can only sterilize and is itself a harmful substance. It requires subsequent detoxification treatment, leading to complex ozone equipment structures and high overall costs. Silver ions can only sterilize air passing through them, exhibiting poor activity. Activated carbon filters typically adsorb particulate matter, but multiple layers are usually required for effective dust removal, resulting in significant space requirements, increased airflow resistance, and the need for regular replacement. Photocatalyst devices typically combine a light source with a photocatalyst filter, also requiring considerable space and generating airflow resistance, leading to higher costs. Negative ion generators produce negative ions that are easily adsorbed and neutralized by particulate matter (such as dust), resulting in a short lifespan and consumption within a short distance, making it difficult to reach distant locations.

[0004] Therefore, there is a need in the field for a new device 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 existing purification devices having relatively simple effects, low efficiency in sterilization and dust removal, large space requirements, and high costs.

[0006] In a first aspect, the present invention provides an ion generator, the ion generator 1 including a housing 11 and a plasma generating module 12 and a negative ion generating module 13 disposed within the housing 11. The negative ion generating module 13 is disposed on the side of the plasma generating module 12. The housing 11 is provided with a ventilation structure 1113. The plasma generating module 12 is configured to ionize air to generate plasma when powered on, and the negative ion generating module 13 is configured to ionize air to generate negative ions when powered on.

[0007] In the preferred embodiment of the above-mentioned ion generator, the housing 11 includes a cover 111 and a base 112 that are fastened to each other, the plasma generating module 12 and the negative ion generating module 13 are both disposed on the base 112, and the ventilation structure 1113 is disposed on the cover 111.

[0008] In the preferred embodiment of the above-mentioned ion generator, the ventilation structure 1113 includes a first ventilation hole 11131 and a second ventilation hole 11132. The first ventilation hole 11131 is at least aligned with a portion of the plasma generating module 12, and the second ventilation hole 11132 is at least aligned with a portion of the negative ion generating module 13.

[0009] In the preferred embodiment of the ion generator described above, the base 112 is provided with a first mounting position and a second mounting position, the first mounting position and the second mounting position are arranged along the length direction of the base 112, the plasma generating module 12 is disposed at the first mounting position, and the negative ion generating module 13 is disposed at the second mounting position.

[0010] In the preferred embodiment of the above-mentioned ion generator, the base 112 includes a first part 1121 and a second part 1122 that are fastened to each other. The cover 111 is fastened to the first part 1121. The first part 1121 is provided with a first mounting hole 11214 and a second mounting hole 11215 on the side opposite to the top of the cover 111. The plasma generating module 12 is disposed in the first mounting hole 11214, and the negative ion generating module 13 is disposed in the second mounting hole 11215.

[0011] In the preferred embodiment of the ion generator described above, the first mounting hole 11214 is configured as a rectangular hole, the long side of which extends along the length direction of the base 112, and the second mounting hole 11215 is located outside the short side of the rectangular hole.

[0012] In the preferred embodiment of the above-described ion generator, the plasma generating module 12 includes a plasma generating section 121. The plasma generating section 121 includes a first electrode 1211, a second electrode 1212, and an insulating dielectric layer 1213 coaxially arranged. The first electrode 1211 is disposed on the outside of the insulating dielectric layer 1213, and the second electrode 1212 passes through the insulating dielectric layer 1213. At least a portion of the plasma generating section 121 extends into the rectangular hole.

[0013] When assembled, the plasma generating unit 121 extends axially along the length direction of the base 112.

[0014] In the preferred embodiment of the above-mentioned ion generator, the ion generator 1 includes one plasma generating module 12 and two negative ion generating modules 13, with the two negative ion generating modules 13 respectively disposed on two sides of the plasma generating module 12.

[0015] In the preferred embodiment of the ion generator described above, the ion generator 1 further includes a power supply module. The plasma generating module 12 and the negative ion generating module 13 are electrically connected to the power supply module, and the power supply module is configured to supply power to the plasma generating module 12 and the negative ion generating module 13.

[0016] In the technical solution of this utility model, the ion generator includes a housing and a plasma generating module and a negative ion generating module disposed within the housing. The negative ion generating module is disposed on the side of the plasma generating module, and the housing is provided with a ventilation structure. This allows air to enter and exit the housing through the ventilation structure. When the ion generator is running, it can simultaneously ionize the air through the plasma generating module and the negative ion generating module to generate plasma and negative ions, and simultaneously release plasma and negative ions. The negative ions are used for dust removal, and the plasma sterilizes the air. Furthermore, due to the high energy of the plasma, it can carry negative ions with the airflow and diffuse into the space where the ion generator is located, further sterilizing and removing dust from the space, thereby achieving better sterilization and dust removal effects.

[0017] Furthermore, the housing includes a cover and a base that interlock with each other. Both the plasma generating module and the negative ion generating module are mounted on the base, and the ventilation structure is mounted on the cover. This allows air to enter the housing through the ventilation structure as it flows through the ion generator, coming into contact with the plasma generating module and the negative ion generating module. The air is then ionized to generate plasma and negative ions, which can sterilize and remove dust from the air. Simultaneously, the air travels through the ventilation structure to the outside of the housing.

[0018] Furthermore, the base is provided with a first mounting position and a second mounting position, which are arranged along the length of the base. The plasma generating module is located at the first mounting position, and the negative ion generating module is located at the second mounting position. In this way, the plasma generating module and the negative ion generating module are placed inside the housing along the length of the base, completely covering the space inside the housing along the length of the base. This allows for the full ionization of the air flowing through the ion generator, producing a large amount of plasma and negative ions.

[0019] Secondly, this utility model also provides an air conditioner equipped with an ion generator 1 as described in any of the aforementioned embodiments.

[0020] It should be noted that this air conditioner has all the technical effects of the aforementioned ion generator, which will not be repeated here. Attached Figure Description

[0030] 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 an ion generator 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.

[0031] It should be noted that in the description of this utility model, the terms "upper," "lower," "inner," "outer," "left," and "right," which indicate 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," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] 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.

[0033] Currently, ozone generators, silver ion generators, and photocatalytic generators typically only perform sterilization. Ozone generated by ozone generators is itself a harmful substance and requires neutralization treatment. Silver ion generators can only sterilize the air flowing through them. Photocatalytic generators require a light source and a catalyst mesh, and occupy a significant amount of space. Activated carbon filters typically only perform dust removal, and usually require multiple layers to achieve good dust removal results, also requiring considerable space. Negative ion generators produce negative ions that are easily adsorbed and neutralized, have a short lifespan, and limited sterilization and dust removal effects. Therefore, the ion generator of this application incorporates both a plasma generation module and a negative ion generation module within its housing. This allows air flowing through the ion generator to be simultaneously ionized by both modules, generating plasma and negative ions. The plasma and negative ions simultaneously sterilize and remove dust from the air, resulting in better sterilization and dust removal effects.

[0034] The following is combined Figures 1 to 6 This paper will describe possible implementations of the ion generator 1 of this utility model.

[0035] like Figure 1 , Figure 5 as well as Figure 6As shown, the wall-mounted air conditioner includes a casing (not shown), a heat exchanger (not shown), and a fan (not shown) installed inside the casing. The casing has an air inlet and an air outlet. Under the action of the fan, indoor air enters the casing through the air inlet to exchange heat with the heat exchanger, and then returns to the indoor space through the air outlet. The wall-mounted air conditioner is equipped with an ion generator 1. An installation structure is provided inside the casing near the air outlet. The ion generator 1 is installed near the air outlet by means of snap-fit, screw-fit, adhesive, or other possible methods. In this way, when the wall-mounted air conditioner is running, at least a portion of the air delivered through the air outlet will flow through the ion generator 1. The ion generator 1 includes a housing 11, a plasma generating module 12, and a negative ion generating module 13. The housing 11 is generally a long strip structure with an internal receiving space. The plasma generating module 12 and the negative ion generating module 13 are installed in this receiving space, with the negative ion generating module 13 located on the side of the plasma generating module 12. A ventilation structure 1113 is provided on the housing 11, so that when air flows through the ion generator 1, it can enter the housing 11 through the ventilation structure 1113, be ionized, and then flow out of the housing 11 through the ventilation structure 1113. When the ion generator 1 is running, plasma is generated by ionizing air through the plasma generation module 12, and negative ions are generated by ionizing air through the negative ion generation module 13, thus releasing plasma and negative ions simultaneously. Plasma typically includes ionized clusters of charged particles, electrons, and reactive oxygen species (ROS). Charged particles and negative ions generated by the negative ion generation module 13 can attach to particles (such as dust), especially negative ions, which easily combine with particulate matter, increasing their weight and causing them to settle or be captured by the filter, thereby achieving a better dust removal effect. Reactive oxygen species can decompose and transform harmful gases (VOCs, etc.) and inactivate microorganisms (bacteria, viruses, etc.) in the air, turning them into harmless or relatively stable substances, thereby achieving a better sterilization effect. Furthermore, due to the high energy of the plasma, as it flows out of the casing 11 with the air, it carries negative ions and diffuses into the space where the wall-mounted air conditioner is located, where it works together with the negative ions to sterilize and remove dust. By combining the sterilization function of plasma with the dust removal function of negative ions in this way, a better sterilization and dust removal effect can be achieved.

[0036] like Figures 1 to 6As shown, the housing 11 includes a cover 111 and a base 112 that are interlocked. The plasma generating module 12 and the negative ion generating module 13 are both mounted on the base 112, and the ventilation structure 1113 is mounted on the cover 111. When air flows through the ion generator 1, it first enters the housing 11 through the ventilation structure 1113, comes into contact with the plasma generating module 12 and the negative ion generating module 13, and is ionized to generate plasma and negative ions. The plasma and negative ions sterilize and remove dust from the air, and at the same time, they travel with the air through the ventilation structure 1113 to the outside of the housing 11 for further sterilization and dust removal of the air in the space.

[0037] Let's combine the following... Figures 1 to 6 This will illustrate the possible implementations of the housing 11 of this utility model.

[0038] like Figures 1 to 6 As shown and in accordance with Figure 1 As shown, the cover 111 is a roughly elongated cover structure. Its two lower edges, which extend along the length of the base 112, are respectively provided with four protruding ends 1112. The inner side of the cover 111 is provided with a first buckle 1111 above the protruding ends 1112.

[0039] The base 112 is generally a long strip structure, comprising a first part 1121 and a second part 1122. The first part 1121 is generally an inverted cover-like structure, with a boss 11211 formed on its upper surface, creating a step-like structure. The shape and size of the boss 11211 are roughly equivalent to the shape and size of the lower end of the cover 111. Eight insertion holes 11212 are provided on the upper surface of the first part 1121 at its junction with the boss 11211. These eight insertion holes 11212 are located on two opposite sides of the boss 11211 along the length of the base 112, each corresponding to a protruding end 1112. A first locking groove 11213 is provided on the side of the boss 11211 at a position corresponding to each insertion hole 11212. Each first locking groove 11213 is located above the insertion hole 11212 and corresponds to a first latch 1111. When the cover 111 and the base 112 are fastened together, the protruding end 1112 is inserted into the insertion hole 11212, the first buckle 1111 and the first slot 11213 are matched and engaged, and the cover 111 covers the outside of the boss 11211.

[0040] The second part 1122 is a roughly rectangular plate-like structure, its side facing the first part 1121 (roughly...) Figure 1A mounting plate 11221 is provided on the upper side of the first part 1122. The mounting plate 11221 extends circumferentially along the second part 1122. Six second buckles 11222 are provided on the outer side of the mounting plate 11221. The six second buckles 11222 are divided into two groups of three. The two groups of second buckles 11222 are respectively provided on the two sides of the mounting plate 11221 extending along the length direction of the base 112. Six second slots (not shown) are provided at corresponding positions on the inner side of the downward extending side of the first part 1121. The first part 1121 and the second part 1122 can be fastened to each other by the interlocking of the second buckles 11222 with the second slots. Obviously, the first buckle 1111 is disposed on the first part 1121 and the first slot 11213 is disposed on the cover 111, or the first buckle 1111 is disposed on the protruding end 1112, or the second buckle 11222 is disposed on the first part 1121 and the second slot is disposed on the second part 1122. This embodiment does not limit the specific snap-fit ​​method between the cover 111 and the first part 1121, or between the first part 1121 and the second part 1122. Of course, the cover 111 and the first part 1121, or the first part 1121 and the second part 1122, can also be snapped together by magnetic adsorption, adhesion, or other possible methods, as long as the snap-fit ​​between the cover 111 and the base 112, and between the first part 1121 and the second part 1122, is achieved. It should also be noted that the cover 111 can also be snapped together with the second part 1122 by snap-fit, magnetic adsorption, adhesion, or other possible methods.

[0041] It should be noted that in this embodiment, the length direction of the base 112 refers to the extension direction of the long side of the base 112, which is approximately... Figure 1 The horizontal direction in the middle.

[0042] like Figure 1 , Figure 5 , Figure 6As shown, the ion generator 1 includes one plasma generating module 12 and two negative ion generating modules 13. These three modules are arranged sequentially along the length of the base 112 in the order of negative ion generating module 13, plasma generating module 12, and negative ion generating module 13. That is, the two negative ion generating modules 13 are respectively located on the left and right sides of the plasma generating module 12. Obviously, the ion generator 1 can also include other numbers of plasma generating modules 12 and negative ion generating modules 13, for example, including two plasma generating modules 12 and one negative ion generating module 13, or including two plasma generating modules 12 and three negative ion generating modules 13, etc. Without departing from the basic principles of this application, those skilled in the art can flexibly select the specific number of plasma generating modules 12 and negative ion generating modules 13 according to the specific application scenario, as long as the ion generator 1 can generate plasma and negative ions simultaneously.

[0043] Continue to refer to Figures 1 to 6 The top of the casing 111 is provided with a transverse rib 1114, which extends along the length of the base 112. The ventilation structure 1113 includes eight first ventilation holes 11131 and two second ventilation holes 11132. Both the first ventilation holes 11131 and the second ventilation holes 11132 are approximately arc-shaped holes extending from the transverse rib 1114 toward the lower edge of the casing 111. The eight first ventilation holes 11131 are arranged along the length of the base 112 and aligned with the plasma generating module 12. The two ventilation holes are located near the left and right ends of the casing 111, respectively, aligned with the negative ion generating module 13. The area of ​​the first ventilation holes 11131 is smaller than the area of ​​the second ventilation holes 11132. In this way, when air flows through the ion generator 1, it will not encounter resistance and will directly reach the plasma generating module 12 and the negative ion generating module 13 through the first ventilation holes 11131 and the second ventilation holes 11132, making full contact with them and then being ionized to generate a sufficient amount of plasma and negative ions. Obviously, multiple second ventilation holes 11132 can also be provided at the positions corresponding to one negative ion generating module 13. It should be noted that the first ventilation hole 11131 and the second ventilation hole 11132 can also be provided as circular holes, elliptical holes, polygonal holes or other types of holes.

[0044] Continue to refer to Figure 1 and Figure 2 The ventilation structure 1113 also includes two third ventilation holes 11133, which are respectively located at both ends of the housing 111. This makes the housing 111 form a long strip-shaped cover structure with openings at both ends, which makes it easier for air to flow into the housing 11 and come into contact with the plasma generating module 12 and the negative ion generating module 13. The ionized air then flows out of the housing 11.

[0045] It should be noted that the specific number of the above-mentioned protruding end 1112, first buckle 1111, first slot 11213, second buckle 11222, second slot, first ventilation hole 11131, second ventilation hole 11132, and third ventilation hole 11133 are merely exemplary descriptions and are not restrictive. Without departing from the basic principles of this application, those skilled in the art can flexibly select the specific number of these structures according to the specific application scenario, as long as the engagement of the cover 111 and the base 112, the first part 1121 and the second part 1122, and the air intake and exhaust of the housing 11 can be achieved.

[0046] like Figure 1 , Figure 3 , Figure 5 as well as Figure 6 As shown, the boss 11211 of the first part 1121 is provided with a first mounting hole 11214 and a second mounting hole 11215. The first mounting hole 11214 is approximately rectangular, and the second mounting hole 11215 is approximately circular. The long side of the first mounting hole 11214 extends along the length direction of the base 112. Viewed along the length direction of the base 112, the two second mounting holes 11215 are located on the outer sides of the two short sides of the first mounting hole 11214. The plasma generating module 12 is located at the first mounting hole 11214, and the negative ion generating module 13 is located at the second mounting hole 11215, thus placing the two negative ion generating modules 13 on both sides of the plasma generating module 12. Obviously, the first mounting hole 11214 and the second mounting hole 11215 can also be arranged along the width direction of the base 112, wherein the width direction of the base 112 is perpendicular to the length direction of the base 112, approximately... Figure 1 The direction is perpendicular to the paper. Of course, one of the second mounting holes 11215 and the first mounting hole 11214 are arranged along the length of the base 112, and the other second mounting hole 11215 and the first mounting hole 11214 are arranged along the width of the base 112. That is, one second mounting hole 11215 is located outside the short side of the first mounting hole 11214, and the other second mounting hole 11215 is located outside the long side of the first mounting hole 11214.

[0047] like Figure 1 , Figure 5 as well as Figure 6As shown, the negative ion generating module 13 includes a mounting base 131 and a carbon brush 132 disposed on the mounting base 131. The mounting base 131 is generally cylindrical. When assembled, the mounting base 131 passes through a second mounting hole 11215, which serves as a second mounting position, and the carbon brush 132 passes through the second mounting hole 11215 and is located inside the housing 11. When the negative ion generating module 13 is powered on, the carbon brush 132 is electrically connected to the negative high-voltage terminal of the power module, resulting in a tip discharge that ionizes the air and generates negative ions. Of course, the negative ion generating module 13 may also not include the carbon brush 132, but instead include a carbon rod disposed on the mounting base 131, or a needle made of one or more metal materials selected from stainless steel, copper, aluminum, tungsten, and molybdenum.

[0048] The following is combined Figure 1 , Figure 5 as well as Figure 6 This paper will describe possible implementations of the plasma generation module 12 of the ion generator 1 of this application.

[0049] like Figure 1 , Figure 5 as well as Figure 6 As shown, the plasma generating module 12 includes a plasma generating section 121, which includes a first electrode 1211, a second electrode 1212, and an insulating dielectric layer 1213. The insulating dielectric layer 1213 is generally cylindrical. The first electrode 1211 is disposed on the outer side of the insulating dielectric layer 1213, and the second electrode 1212 passes through the inner side of the insulating dielectric layer 1213. When assembled, the first electrode 1211, the second electrode 1212, and the insulating dielectric layer 1213 are coaxially arranged. The first electrode 1211 and the second electrode 1212 are electrically connected to a power source, and the electrical polarities of the two electrodes are opposite after the plasma generating module 12 is powered on. In this way, a potential difference can be formed between the two electrodes, thereby forming a high-voltage electric field. Under the blocking effect of the insulating dielectric layer 1213, the electric field formed between the two electrodes can be made more uniform. This uniform electric field extends along the axial direction of the insulating dielectric layer 1213 and surrounds the circumference of the insulating dielectric layer 1213. In this way, no matter which direction the air flows through the plasma generating module 12, it can be ionized by the electric field distributed circumferentially along the insulating dielectric layer 1213 to generate high-density, high-energy plasma, instead of producing harmful ozone. No subsequent harmless treatment is required, and a better sterilization effect is achieved.

[0050] It should be noted that in this embodiment, the axial direction of the insulating dielectric layer 1213 is approximately... Figure 1 The horizontal direction in the middle.

[0051] In one possible implementation, the first electrode 1211 and the second electrode 1212 can be made of metal materials such as copper, stainless steel, and tungsten, and the insulating dielectric layer 1213 can be made of inorganic insulating materials with a large dielectric constant such as ceramics and glass.

[0052] Preferably, the first electrode 1211 is made of brass, the second electrode 1212 is made of stainless steel, and the insulating dielectric layer 1213 is made of ceramic. This ensures that the first electrode 1211 can discharge continuously and stably, the second electrode 1212 has high hardness and is not easily oxidized during discharge, allowing for long-term use, and the insulating dielectric layer 1213 has a high dielectric constant, ensuring effective insulation between the first electrode 1211 and the second electrode 1212, thereby ensuring the lifespan of the plasma generator 121.

[0053] like Figure 1 , Figure 5 , Figure 6 As shown, the insulating dielectric layer 1213 is generally cylindrical, with two recessed regions 12131 on its outer wall. Each recessed region 12131 extends circumferentially along the insulating dielectric layer 1213, forming a generally annular recessed region 12131. The two recessed regions 12131 are arranged sequentially along the axial direction of the insulating dielectric layer 1213. The first electrode 1211 includes a main body 12111 and a mounting part 12112 that are electrically connected to each other. The main body 12111 is configured as a cylindrical structure and extends axially along the insulating dielectric layer 1213. This cylindrical structure can be directly cast integrally from brass, or it can be made from brass into two rectangles, which are then bent and their sides are joined together to form the structure. The main body 12111 has a plurality of first through holes 12113, each of which is circular. These circular holes are evenly arranged in an array along the circumference of the main body 12111, with equal distances between adjacent holes. When the plasma generating module 12 is energized, an electric field is generated between the first electrode 1211 and the second electrode 1212, and also at each of the first through holes 12113, with the electric field at each hole being relatively uniform. The mounting portion 12112 is approximately annular, with a plurality of notches near its outer edge, evenly distributed along the circumference of the mounting portion 12112. The insulating dielectric layer 1213 has two ends along its axial direction (approximately...) Figure 1Annular mounting plates 12132 and 11221 are respectively provided at the left and right ends of the insulating dielectric layer 1213 shown. The outer diameter of the annular mounting plate 12132 and 11221 is larger than the outer diameter of the insulating dielectric layer 1213 and approximately equal to the outer diameter of the mounting portion 12112. The center of the annular mounting plate 12132 and 11221 is located on the axis of the insulating dielectric layer 1213. One end of the insulating dielectric layer 1213 (approximately...) Figure 1 The right end of the insulating dielectric layer 1213 shown has an annular mounting groove formed near the annular mounting plate 11221. A locking position is formed between the annular mounting groove and the annular mounting plate 11221, and the mounting part 12112 is engaged in this locking position. The end of the main body 12111 near the mounting part 12112 (approximately...) Figure 1 Multiple insertion structures 121111 extend outward from the right end of the main body 12111 shown in the diagram. Each insertion structure 121111 extends outward along the axial direction of the main body 12111 and is approximately arc-shaped. Each insertion structure 121111 corresponds to a notch. When assembled, each insertion structure 121111 is inserted into its corresponding notch. The main body 12111 is coaxially arranged with the insulating dielectric layer 1213, and the outer edge of the main body 12111 is flush with the outer edges of the mounting portion 12112 and the annular mounting plate 12132 (mounting plate 11221). Through the adaptation of the annular mounting plate 12132 (mounting plate 11221), the mounting portion 12112, and the insertion structures 121111 with the notch, the first electrode 1211 is fixedly positioned on the first side (approximately the outer side of the insulating dielectric layer 1213). When assembled, the inner wall of the first electrode 1211 has a gap with at least one recessed region 12131 of the insulating dielectric layer 1213, thus forming a flow channel at least at one point between the first electrode 1211 and the insulating dielectric layer 1213. When air flows through the plasma generating module 12, at least a portion of the air enters into the flow channel through the first through-hole 12113 or exits the flow channel through the first through-hole 12113. While in the flow channel and during the process of entering and exiting the flow channel, the air can be sufficiently ionized by the electric field between the first electrode 1211 and the second electrode 1212, as well as the electric field at the first through-hole 12113, thereby generating more plasma. Obviously, there can also be a gap between the inner wall of the first electrode 1211 and the non-recessed region 12131 of the insulating dielectric layer 1213, which facilitates air passing through the electric field formed between the first electrode 1211 and the second electrode 1212, and thus being better ionized to generate plasma.

[0054] It should be noted that the recessed region 12131 may not be annular, but may be arc-shaped, curved, wavy, or other possible shapes. Obviously, the outer wall of the insulating dielectric layer 1213 may have only one recessed region 12131, or three, four, or more recessed regions 12131. Without departing from the basic principles of this application, those skilled in the art can flexibly determine the specific shape and number of the recessed regions 12131 according to the specific application scenario, as long as a flow channel is formed between the inner wall of the first electrode 1211 and the insulating dielectric layer 1213.

[0055] It should be noted that the annular mounting plate 12132 and mounting plate 11221 can be integrally formed with the insulating dielectric layer 1213, or they can be disposed at both ends of the insulating dielectric layer 1213 by means of screwing, snap-fitting, or bonding. The material used to prepare the annular mounting plate 12132 and mounting plate 11221 can be the same as or a different insulating material than the insulating dielectric layer 1213. Furthermore, the outer diameter of the annular mounting plate 12132 and mounting plate 11221 can be smaller or larger than the outer diameter of the mounting portion 12112.

[0056] It should be noted that the first electrode 1211 may also consist only of the main body 12111. In this case, the first electrode 1211 can be disposed on the outside of the insulating dielectric layer 1213 by embedding, snapping, bonding, or other possible means. Taking the first electrode 1211 snapped on the outside of the insulating dielectric layer 1213 as an example, the first electrode 1211 is provided with snap-fit ​​parts (such as buckles, snap blocks, etc.), and the insulating dielectric layer 1213 is provided with multiple mating parts (such as slots, slot holes, etc.) at corresponding positions. The first electrode 1211 is snapped on the outside of the insulating dielectric layer 1213 through the matching connection between the snap-fit ​​parts and the mating parts.

[0057] like Figure 1 , Figure 5 , Figure 6As shown, the insulating dielectric layer 1213 is provided with a second through hole 12133, which penetrates the insulating dielectric layer 1213 along its axial direction. The cross-section of the second through hole 12133 is approximately circular, with its center located on the axis of the insulating dielectric layer 1213. The second electrode 1212 is a stainless steel rod with a circular cross-section. The diameter of the second through hole 12133 is slightly larger than the diameter of the stainless steel rod. The second electrode 1212 is inserted through the second through hole 12133, thus placing the second electrode 1212 on the second side of the insulating dielectric layer 1213. When assembled, the first electrode 1211, the second electrode 1212, and the insulating dielectric layer 1213 are coaxially arranged. In this way, the distance between the first electrode 1211 and the second electrode 1212 is equal everywhere. When the plasma generating module 12 is energized, all potential differences between the first electrode 1211 and the second electrode 1212 are exactly the same, thereby generating a more uniform electric field between them. Obviously, the cross-section of the second through hole 12133 can also be set to an ellipse, polygon, square or other possible shapes, as long as it allows the stainless steel rod to pass through.

[0058] Continue to refer to Figures 1 to 6 The length of the first mounting hole 11214 is approximately equal to the axial dimension of the first electrode 1211. Two mounting platforms 11216 are respectively provided on the left and right sides of the first mounting hole 11214. Each mounting platform 11216 extends along the width of the first mounting hole 11214 and has two mounting posts 11217 extending perpendicular to the top side of the first part 1121. The two mounting posts 11217 are arranged along the width of the first mounting hole 11214. A first through hole 11218 is provided between the two mounting posts 11217, penetrating the top side of the first part 1121. Thus, the first mounting hole 11214 and the mounting platforms 11216 constitute the first mounting position for the plasma generating module 12.

[0059] The plasma generating unit 121 also includes two strip-shaped mounting plates 1214, each strip-shaped mounting plate 1214 having two mounting holes 12141, and a second through hole 12142 disposed between the two mounting holes 12141. The second electrode 1212 extends to the outside of the insulating dielectric layer 1213 at both ends along its axial direction, and slots 12121 are respectively provided at both ends of the second electrode 1212, the slots 12121 being recessed inward from the ends of the second electrode 1212. The second electrode 1212 has third through holes 12122 respectively provided near both ends, the third through holes 12122 penetrating the second electrode 1212 and the slots 12121 radially through the second electrode 1212. During assembly, the lower part of the plasma generator 121 extends into the first mounting hole 11214, and the strip mounting pieces 1214 are inserted into the corresponding slots 12121. The second through holes 12142 are aligned with the corresponding third through holes 12122. Then, the mounting holes 12141 on the strip mounting pieces 1214 are aligned with the corresponding mounting posts 11217 to adapt to the corresponding mounting posts 11217, thereby assembling the second electrode 1212 with the base 112 and securing the plasma generator 121 on the base 112. When assembled, at least a portion of the plasma generator 121 extends into the base 112 through the first mounting hole 11214, and the axis of the plasma generator 121 extends along the length of the base 112. Furthermore, the first via 11218, the second via 12142, and the third via 12122 are aligned with each other, so that the electrical connector connected to the power supply can pass through these vias and be electrically connected to the second electrode 1212, thereby ensuring the power supply to the second electrode 1212.

[0060] It should be noted that the long side of the first mounting hole 11214 may not extend along the length direction of the base 112, but may form an angle with the length direction of the base 112. Of course, when the ion generator 1 includes other numbers of plasma generating modules 12 and negative ion generating modules 13, a corresponding number of first mounting holes 11214 and second mounting holes 11215 will also be formed on the base 112. When there are multiple first mounting holes 11214 and second mounting holes 11215, each first mounting hole 11214 and second mounting hole 11215 may not be arranged along the length direction of the base 112, but may be arranged along the width direction of the base 112, or the line connecting the centers of two first mounting holes 11214 and second mounting holes 11215, or the line connecting the centers of two first mounting holes 11214, or the line connecting the centers of two second mounting holes 11215 may form an angle with the length direction of the base 112. Without departing from the basic principles of this application, those skilled in the art can flexibly select the number of the first mounting hole 11214 and the second mounting hole 11215, as well as the specific arrangement of each mounting hole, according to the specific application scenario, as long as the installation of the plasma generating module 12 and the negative ion generating module 13 can be achieved.

[0061] It should be noted that the first mounting position and the second mounting position may also include the first mounting hole 11214 and the second mounting hole 11215, or they may include the first groove and the second groove. Correspondingly, the mounting platform 11216 is adjusted to be a slot or hole set in the first groove, and the strip mounting piece 1214 is correspondingly provided with a buckle or a block. The second electrode 1212 can also be fixedly installed by the adaptation of the buckle (or block) and the slot (or hole). Obviously, the first mounting position and the second mounting position can also be set in other possible forms. For example, the first mounting position includes the first groove and the second mounting position includes the second mounting hole 11215, or the first mounting position includes the first mounting hole 11214 and the second mounting position includes the second groove, etc. Obviously, it is also possible to provide only the first mounting hole 11214 or the mounting platform 11216. Taking the mounting platform 11216 as an example, the height of the mounting platform 11216 is approximately equal to the radius of the first electrode 1211. By adapting the mounting hole 12141 on the strip mounting piece 1214 to the mounting post 11217 on the mounting platform 11216, the plasma generating unit 121 can also be fixed to the base 112. Of course, the plasma generating module 12 and the negative ion generating module 13 can also be fixed in the housing 11 by screwing, snapping, bonding, or other possible methods. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific configuration of the first mounting position and the second mounting position according to the specific application scenario, as long as the installation of the plasma generating module 12 and the negative ion generating module 13 can be achieved.

[0062] like Figure 1 , Figure 5 as well as Figure 6 As shown, the first electrode 1211 also includes an electrical connection end 12114, which extends outward from the outer edge of the mounting portion 12112. It is generally elongated and rounded at the end furthest from the mounting portion 12112. When assembled, the electrical connection end 12114 extends downward from the first electrode 1211, passes through the first mounting hole 11214, and extends into the base 112. It then connects to the power module via an electrical connector, ensuring power supply to the first electrode 1211. Alternatively, the first electrode 1211 may not have an elongated electrical connection end 12114. Instead, an electrical connection portion can be formed on the main body 12111 or the mounting portion 12112. An electrical connector, connected to the power supply, passes through a slot and connects to this electrical connection portion, thus achieving electrical connection between the first electrode 1211 and the power module.

[0063] Continue to refer to Figure 6 The plasma generating module 12 also includes an indicator light 122, which can be an LED strip. The indicator light 122 displays the operating status of the plasma generating module 12. For example, a red indicator light 122 indicates that the plasma assembly is not operating, while a green indicator light 122 indicates that the plasma assembly is operating normally, and so on. Obviously, the indicator light 122 can also be an LED bead, etc. The second part 1122 also has a limiting block 11223 near the mounting plate 11221. This limiting block 11223 and the mounting plate 11221 enclose an installation space, and the indicator light 122 is installed within this space by screwing, snap-fitting, or other possible methods. Obviously, the plasma generating module 12 may also be without the indicator light 122.

[0064] In one possible implementation, the ion generator 1 further includes a power supply module electrically connected to the plasma generating module 12 and the negative ion generating module 13, respectively, to supply power to the plasma generating module 12 and the negative ion generating module 13, ensuring the stable operation of the ion generator 1. The power supply module can be a high-voltage battery pack, which can process the input DC or AC power through an EMI processing circuit and a lightning protection circuit, then boost the low voltage to AC high voltage (e.g., 220V) through a pulse oscillation circuit, overvoltage current limiting, and high / low voltage isolation circuits, and then convert it to DC high voltage (including DC positive and DC negative high voltage) through a voltage multiplier circuit. The plasma generating module 12 is electrically connected to the AC high-voltage terminal of the high-voltage battery pack. During operation, the first electrode 1211 and the second electrode 1212 are always opposite in polarity, and the negative ion generating module 13 is electrically connected to the DC negative high voltage terminal of the high-voltage battery pack. Obviously, it is also possible that the power supply module includes an AC high-voltage power supply and a DC high-voltage power supply, with the negative ion generating module 13 connected to the negative high-voltage terminal of the DC high-voltage power supply and the plasma generating module 12 electrically connected to the AC high-voltage power supply.

[0065] In summary, in the preferred embodiment of this utility model, by setting a plasma generating module 12 and a negative ion generating module 13 inside the housing 11, and by setting a ventilation structure 1113 on the housing 11, two different types of ion generating modules are simultaneously installed inside the housing 11. When the ion generator 1 is running, it can ionize the air to generate plasma and negative ions. Through the combined action of plasma and negative ions, the air can be effectively sterilized and dust-removed. Furthermore, the high-energy plasma can also carry negative ions into the indoor space for further sterilization and dust removal, resulting in better sterilization and dust removal effects. By setting one first mounting position and two second mounting positions on the base 112, and arranging the first and second mounting positions along the length of the base 112, the plasma generating module 12 and the negative ion generating module 13 are also installed inside the housing 11 along the length of the base 112, achieving full coverage. This allows for more efficient ionization of the air flowing through the ion generator 1 to generate more plasma and negative ions.

[0066] In addition, this utility model also provides an air conditioner equipped with the aforementioned ion generator 1.

[0067] It should be noted that this air conditioner has all the technical effects of the aforementioned ion generator 1, which will not be repeated here.

[0068] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.
