Abstract
Description
Technical Field
[0001] This utility model relates to the field of air treatment technology, specifically providing an ion generating device. Background Technology
[0002] Air conditioners typically regulate indoor temperature by exchanging heat between indoor air and an indoor heat exchanger. Over time, this process can lead to the accumulation of bacteria, viruses, and particulate matter inside the air conditioner. When indoor air exchanges heat with the heat exchanger, it carries these bacteria, viruses, and particulate matter from the air conditioner into the indoor space, resulting in decreased indoor air quality and, in severe cases, harming people's health.
[0003] Therefore, people usually equip air conditioners with a sterilization device, such as an ultraviolet (UV) sterilization device, to perform sterilization. However, UV sterilization devices typically only have a sterilization effect within their irradiation range, and both the sterilization effect and range are relatively limited. To increase its irradiation range, adjustments and redesigns to its assembly and structure are usually required, making the process quite complex.
[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

The plasma generating component (2) is configured to ionize air to generate plasma when energized, and the ion emitting electrode (3) is configured to ionize air to generate negative ions when energized. The ion emitting electrode (3) is disposed on at least one side of the plasma generating component (2).
[0007] In the preferred embodiment of the above-mentioned ion generating device, the ion generating device includes a plasma generating component (2) and two ion emitting electrodes (3), with the two ion emitting electrodes (3) respectively disposed on both sides of the plasma generating component (2).
[0008] In the preferred embodiment of the above-mentioned ion generating device, the ion generating device includes two plasma generating components (2) and two ion emitting electrodes (3), wherein one ion generating component (2) is provided with an ion emitting electrode (3) and the other plasma generating component (2) on both sides respectively.
[0009] In the preferred embodiment of the above-mentioned ion generating device, the housing (1) is provided with a first mounting groove (11) and a mounting base (12), at least a portion of the mounting base (12) is located on the side of the first mounting groove (11), the plasma generating assembly (2) is disposed in the first mounting groove (11), and the ion emitting electrode (3) is disposed on the mounting base (12).
[0010] In the preferred embodiment of the above-mentioned ion generating device, the plasma generating component (2) includes a first electrode (21) and a second electrode (22) arranged opposite to each other. The first electrode (21) and the second electrode (22) are electrically connected to the positive high voltage end and the negative high voltage end, respectively. The first electrode (21) is provided with at least one through hole (211), and the second electrode (22) includes at least one tip (221). When assembled, at least a portion of the tip (221) is aligned with the through hole (211).
[0011] In the preferred embodiment of the above-mentioned ion generating device, the first electrode (21) is configured as a strip structure.
[0012] In the preferred embodiment of the above-mentioned ion generating device, the ion generating device further includes a bactericidal light generating component (4), which is disposed in the housing (1) and is configured to emit bactericidal light outward after being powered on.
[0013] In the preferred embodiment of the above-mentioned ion generating device, a second mounting groove (13) is provided on the side of the housing (1), and the bactericidal light generating component (4) is disposed in the second mounting groove (13).
[0014] In the preferred embodiment of the above-mentioned ion generating device, the bactericidal light generating component (4) includes LED beads (41).
[0015] In the preferred embodiment of the above-mentioned ion generating device, the housing (1) is provided with a light-transmitting element (5) at a position corresponding to the second mounting groove (13). The light-transmitting element (5) is configured to allow bactericidal light to pass through. When assembled, the outer surface of the light-transmitting element (5) is flush with the side of the housing (1).
[0016] In the technical solution of this utility model, the ion generating device includes a housing, at least one plasma generating component and at least one ion emitting electrode disposed on the housing. The ion emitting electrode, when energized, can ionize air to generate negative ions. These negative ions can disinfect and sterilize the air, and also provide health benefits to the human body. The plasma generating component, when energized, can ionize air to generate plasma. Furthermore, an ion emission electrode is provided on at least one side of the plasma generating component. This ensures that when air passes through the ion generating device, at least a portion of the air is ionized by the plasma generating component to generate plasma, while the remaining air is ionized by the ion emission electrode to generate negative ions. This arrangement of the plasma generating component and ion emission electrode, with the electrode located on at least one side of the plasma generating component, covers the entire ion generating device. The air flowing through the device is fully ionized to generate plasma and negative ions. These plasmas and negative ions not only sterilize the air flowing through them but also diffuse with the airflow to other areas, sterilizing those areas as well. This effectively increases the sterilization range and achieves a better sterilization effect.
[0017] Furthermore, the housing is provided with a first mounting groove and a mounting base. At least a portion of the mounting base is located on the side of the first mounting groove. The plasma generating assembly is disposed within the first mounting groove, and the ion emitting electrode is disposed on the mounting base. This effectively positions the ion emitting electrode on the side of the plasma generating assembly, fully ionizing the air flowing through the ion generating device and completely covering the device. Moreover, the plasma generating assembly and the ion emitting electrode are mounted on the housing, integrating them together for easy installation.
[0018] Furthermore, the ion generating device also includes a germicidal light generating component, which is located on the side of the housing and is configured to emit germicidal light outward when powered on. In this way, the ion generating device can not only generate plasma and negative ions by ionizing air through the plasma generating component and ion emitting electrode, but also emit germicidal light for irradiation through the germicidal light generating component. Under the combined action of plasma, negative ions and germicidal light, the sterilization process can be better carried out and a better sterilization effect can be obtained.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0033] Currently, the ultraviolet sterilization devices installed on air conditioners can only sterilize within their irradiation range, resulting in a limited sterilization area and poor sterilization effect. To address this, the ion generating device of this application includes a housing, at least one plasma generating component, and at least one ion emitting electrode. The plasma generating component has an ion emitting electrode on at least one side. The plasma generating component and ion emitting electrode can fully cover the ion generating device, sufficiently ionizing the air flowing through it to generate enough plasma and negative ions. This sterilizes both the air and the surrounding space, effectively increasing the sterilization range and improving the sterilization effect.
[0034] The following is combined Figures 1 to 8 This paper will describe possible implementations of the ion generating device of this invention.
[0035] like Figures 1 to 8As shown, the ion generating device includes a housing 1, a plasma generating component 2, and an ion emitting electrode 3 disposed on the housing 1. The housing 1 is generally a cuboid structure. The plasma generating component 2, when energized, ionizes air to generate plasma, and the ion emitting electrode 3, when energized, ionizes air to generate negative ions. The plasma includes not only negative and positive ions but also ground-state or excited-state atoms or molecules, categorized as short-lived reactive particles (such as O, OH, HO2, etc.) and long-lived reactive ions (such as excited-state N2, H2O2, etc.). This plasma removes bacteria and viruses from the air through the penetration effect of high-speed ions, the electric field effect, and the action of high-energy ions and active free radicals. Negative ions can disinfect and sterilize the air, and upon entering an indoor space, they can increase the concentration of negative ions in the indoor space, thus providing health benefits to the human body. The plasma generating component 2 of this invention has an ion emitting electrode 3 disposed on at least one side, thus covering the entire ion generating device through the plasma generating component 2 and the ion emitting electrode 3. When air flows through the ion generator, some air comes into contact with the plasma generating component 2 and is ionized to generate plasma, while another portion comes into contact with the ion emitting electrode 3 and is ionized to generate negative ions. This means that the air flowing through the ion generator can contact and be ionized by at least one of the plasma generating component 2 and the ion emitting electrode 3, thus achieving comprehensive coverage and more thorough ionization of the air flowing through it. This plasma and negative ions flow out of the housing 1 with the airflow and enter the indoor space where it is located. This not only sterilizes the air flowing through the ion generator but also sterilizes the air and objects in the indoor space it enters, effectively increasing the sterilization range and achieving a better sterilization effect. The plasma generating component 2 and the ion emitting electrode 3 do not cause harm to the human body during operation, and the generated plasma and negative ions are also harmless to the human body. In fact, negative ions are beneficial to human health. Therefore, there are no restrictions on the installation location; it can be placed in any possible location. Furthermore, since the plasma generating component 2 and the ion emitting electrode 3 are integrated on the housing 1, the ion generating device can be installed in a preset position to sterilize the space flowing through that position, making installation very convenient.
[0036] In one possible implementation, the ion generating device includes a plasma generating component 2 and two ion emitting electrodes 3, which are described below in conjunction with... Figures 1 to 5 This will illustrate the possible implementation methods of an ion generating device.
[0037] like Figures 1 to 5 As shown and in accordance with Figure 4As shown, the housing 1 has a first mounting groove 11 and two mounting seats 12. The first mounting groove 11 is formed by an inward indentation from the top of the housing 1, and is roughly open upwards with a roughly rectangular front projection. The two mounting seats 12 are respectively located on the left and right sides of the first mounting groove 11. The plasma generating assembly 2 is disposed within the first mounting groove 11, and the two ion emitting electrodes 3 are respectively disposed on the two mounting seats 12, thus placing the two ion emitting electrodes 3 on the left and right sides of the plasma generating assembly 2. When air flows through the ion generating device, some air comes into contact with the central plasma generating assembly 2 and is ionized to generate plasma, while the other part of the air comes into contact with the ion emitting electrodes 3 on both sides and is ionized to generate negative ions.
[0038] Continue to refer to Figure 1 and Figure 2 The ion generator also includes a sterilization light generating component 4, which comprises two LED beads 41 that emit ultraviolet light when powered on. A second mounting groove 13 is formed by an inward indentation in the center of the front side of the housing 1. The bottom of the second mounting groove 13 is smaller than the size of the front side of the housing 1. The two LED beads 41 are arranged side-by-side at the bottom of the second mounting groove 13, one on the left and one on the right. Thus, when the ion generator is powered on, the ultraviolet light emitted by the LED beads 41 can irradiate the front side of the ion generator, sterilizing the surfaces of objects and the air within its irradiation range.
[0039] Continue to refer to Figure 1 and Figure 2 The housing 1 has a recessed mounting position 14 corresponding to the second mounting groove 13. A light-transmitting element 5 is provided at the mounting position 14, which is designed to allow ultraviolet light to pass through. The light-transmitting element 5 can be made of materials such as silicate glass, plexiglass, or polycarbonate, as long as it allows ultraviolet light to pass through. The light-transmitting element 5 is roughly rectangular, and its size is larger than the size of the bottom of the second mounting groove 13. When assembled, the light-transmitting element 5 covers the outside of the LED beads 41, and the outer surface of the light-transmitting element 5 is flush with the front side of the housing 1, resulting in a neat and aesthetically pleasing appearance.
[0040] In another possible implementation, the ion generating device includes two plasma generating components 2 and two ion emitting electrodes 3, which are described below in conjunction with... Figures 6 to 8 This will illustrate the possible implementation methods of an ion generating device.
[0041] like Figures 6 to 8 As shown and in accordance with Figure 8 As shown in the diagram, the housing 1 is provided with two first mounting slots 11 and two mounting bases 12. The two first mounting slots 11 are along the length direction of the housing 1 (approximately). Figure 8The first mounting groove 11 is formed by a recess inward from the top of the housing 1, and is generally open upward, with a roughly rectangular front projection. Two mounting seats 12 are respectively located on the side of the first mounting groove 11 away from the other first mounting groove 11 (approximately...). Figure 8 (The left side of the left first mounting groove 11 and the right side of the right first mounting groove 11 are shown). Two plasma generating components 2 are respectively disposed in the first mounting groove 11, and two ion emitting electrodes 3 are respectively disposed on two mounting bases 12, so that they are arranged along the length of the housing 1 in the manner of one ion emitting electrode 3, two plasma generating components 2, and another ion emitting electrode 3. When air flows through the ion generating device, part of the air comes into contact with the two plasma generating components 2 in the middle and is ionized to generate plasma, while the other part of the air comes into contact with the ion emitting electrodes 3 on both sides and is ionized to generate negative ions.
[0042] Continue to refer to Figure 6 and Figure 7 The ion generator also includes a sterilization light generating component 4, which comprises three LED beads 41 that emit ultraviolet light when powered on. A second mounting groove 13 is formed inwardly at the position corresponding to the spacer 15 on the front side of the housing 1. The bottom of the second mounting groove 13 is slightly smaller than the size of the spacer 15. The three LED beads 41 are arranged sequentially along the length of the housing 1 at the bottom of the second mounting groove 13. Thus, when the ion generator is powered on, the ultraviolet light emitted by the LED beads 41 can irradiate the front of the ion generator, sterilizing the surfaces of objects and the air within its irradiation range.
[0043] Continue to refer to Figure 6 and Figure 7 The housing 1 has a recessed mounting position 14 corresponding to the second mounting groove 13. A light-transmitting element 5 is provided at the mounting position 14, which is designed to allow ultraviolet light to pass through. The light-transmitting element 5 can be made of materials such as silicate glass, plexiglass, or polycarbonate, as long as it allows ultraviolet light to pass through. The light-transmitting element 5 is roughly rectangular, and its size is larger than the size of the bottom of the second mounting groove 13. When assembled, the light-transmitting element 5 covers the outside of the LED beads 41, and the outer surface of the light-transmitting element 5 is flush with the front side of the housing 1, resulting in a neat and aesthetically pleasing appearance.
[0044] In one possible implementation, the light-transmitting element 5 may also be designed with a logo, symbol, such as "AIP Ultra-Clean System," so that users can accurately identify the ion generating device.
[0045] It should be noted that although the above description uses examples of the germicidal light generating component 4 including two LED beads 41 and three LED beads 41, it is clear that the germicidal light generating component 4 can also include only one LED bead 41, or four, five, or more LED beads 41. Of course, the germicidal light generating component 4 can also include an LED tube that emits ultraviolet light when powered on. Without departing from the basic principles of this application, those skilled in the art can flexibly choose the specific type and quantity of the germicidal light generating component 4 according to the specific application scenario, as long as it can generate ultraviolet light when powered on.
[0046] Although the above description uses the example of the germicidal light generating component 4 being installed in the second mounting groove 13, it is clear that the housing 1 may not necessarily have the second mounting groove 13. For example, the front side of the housing 1 may have a mounting platform protruding outwards, and the LED bead 41 may be mounted on this mounting platform. Alternatively, the LED bead 41 may be installed inside the housing 1, with a through hole 211 provided at the corresponding position to allow the emitted ultraviolet light to irradiate outwards. Of course, the LED bead 41 may also not be installed on the side of the housing 1, but rather on the top or bottom of the housing 1 (according to...). Figure 4 (as shown in the diagram) or other possible positions. Without departing from the basic principles of this application, those skilled in the art can flexibly choose according to the specific application scenario, as long as the LED bead 41 can be set on the housing 1.
[0047] It should also be noted that the sterilizing light can also be far-infrared light, pulsed light, etc. Taking far-infrared light as an example, the sterilizing light generating component 4 includes a far-infrared sterilizing lamp that can emit far-infrared light. Of course, the sterilizing light can also be other types of light, as long as the light can sterilize items, air, etc. within its irradiation range.
[0048] It should be noted that although the above descriptions use examples of an ion generating device including one plasma generating component 2 and two ion emitting electrodes 3, and two plasma generating components 2 and two ion emitting electrodes 3, it is clear that the ion generating device can also include more or fewer plasma generating components 2 and ion emitting electrodes 3. Accordingly, the number of first mounting slots 11 and mounting bases 12 provided on the housing 1 is also adjusted adaptively so that the corresponding number of plasma generating components 2 and ion emitting electrodes 3 can be assembled on the housing 1. For example, the ion generating device includes three plasma generating components 2 and three ion emitting electrodes 3. Three first mounting slots 11 are arranged sequentially along the length of the housing 1. Two mounting bases 12 are respectively located outside the two leftmost and rightmost first mounting slots 11, and another mounting base 12 is located between one pair of adjacent first mounting slots 11. The three plasma generating components 2 and three ion emitting electrodes 3 are respectively located in each first mounting slot 11 and each mounting base 12. Without departing from the basic principles of this application, those skilled in the art can flexibly select the number of plasma generating components 2 and ion emitting electrodes 3 according to specific application scenarios, as long as ion emitting electrodes 3 are provided on at least one side of the plasma generating components 2, and the air can be ionized to generate plasma and negative ions.
[0049] The following example uses an ion generator comprising a plasma generating component 2 and two ion emitting electrodes 3, and combines them with... Figures 1 to 5 This will illustrate the possible implementation methods of the plasma generating component 2 and the ion emitting electrode 3.
[0050] like Figures 1 to 5 As shown and in accordance with Figure 4 As shown, the plasma generating assembly 2 includes a first electrode 21 and a second electrode 22 arranged opposite to each other. The first electrode 21 is electrically connected to the positive high-voltage terminal of the power module and is roughly strip-shaped, with multiple through holes 211 arranged sequentially along the length of the first electrode 21. The second electrode 22 is connected to the negative high-voltage terminal of the power module and includes multiple tips 221 located below the first electrode 21. When assembled, at least a portion of each tip 221 is aligned with the through hole 211. Thus, when the plasma generating assembly 2 is energized, a plasma field is formed between each set of tips 221 and through holes 211, thereby forming multiple plasma fields along the length of the first electrode 21. The plasma fields cover the entire area, thus ionizing more air and generating more plasma.
[0051] Of course, the first electrode 21 and the second electrode 22 can also be arranged alternately rather than opposite each other. In this case, one of the first electrode 21 and the second electrode 22 is connected to the negative high-voltage terminal, and the other is grounded or connected to zero potential. The power module is connected to an external power source to supply power to the ion generator. It can process the input DC or AC power through EMI processing circuit and lightning protection circuit, and then through pulse oscillation circuit, overvoltage current limiting, high and low voltage isolation circuit, etc., to raise the low voltage to AC high voltage. Then, after rectification and filtering by special grade electronic materials, pure DC negative high voltage and DC positive high voltage are obtained, forming the positive high voltage terminal and negative high voltage terminal for powering the ion generator.
[0052] The first electrode 21 and the second electrode 22 can be made of one or more metallic materials selected from stainless steel, copper, aluminum, tungsten, and molybdenum, or they can be made of conductive non-metallic materials such as graphite and carbon fiber, as long as a plasma field can be formed between the first electrode 21 and the second electrode 22.
[0053] It should be noted that the first electrode 21 can also be set in other possible shapes such as ellipse, rectangle, square, triangle, etc., and the through hole 211 set thereon can also be in other possible shapes such as triangle, ellipse, irregular shape, rectangle, etc.
[0054] Although the above description uses the example of the first electrode 21 being positioned above the second electrode 22 as an example, it is clearly only an exemplary illustration. The first electrode 21 can also be positioned below the second electrode 22. Furthermore, the first electrode 21 can be electrically connected to the negative high-voltage terminal, and the second electrode 22 can be electrically connected to the positive high-voltage terminal. A wire-passing hole is provided at the bottom of the first mounting groove 11, through which electrical wires can pass to ensure that the first electrode 21 and the second electrode 22 are electrically connected to the power module.
[0055] like Figures 1 to 5 As shown and in accordance with Figure 4 As shown in the diagram, the second electrode 22 is generally a sheet-like structure, with multiple tips 221 extending outward from one of its long sides along the extension direction of its short sides (approximately). Figure 4(Extending vertically upwards in the middle). The bottom of the first mounting groove 11 forms a slot 111, and the second electrode 22 is engaged in the slot 111. When engaged, the tip 221 is located above the slot 111, that is, above the bottom of the first mounting groove 11 and inside the first mounting groove 11. Two mounting posts 112 are provided in the first mounting groove 11. The two mounting posts 112 are located near the groove wall of the first mounting groove 11 along the length direction of the housing 1. When the second electrode 22 is engaged, its two ends abut against the parts of the two mounting posts 112 near the bottom of the groove. The mounting post 112 on the left is slightly lower than the mounting post 112 on the right. The top of the left mounting post 112 is provided with a mounting hole 1121, which extends along the height direction of the mounting post 112. The part of the right mounting post 112 near the top is cylindrical. The first electrode 21 has a circular hole at each end. During installation, the circular hole near the right end is fitted onto the right mounting post 112, and the circular hole near the left end is aligned with the mounting hole 1121. Then, fasteners (such as screws or bolts) are used to secure it, thus installing the first electrode 21 into the first mounting groove 11. Alternatively, the left mounting post 112 can be slightly higher than the right mounting post 112. In this case, the top portion of the left mounting post 112 is cylindrical, and the top of the right mounting post 112 has the mounting hole 1121. Of course, both mounting posts 112 can also have cylindrical portions near the top, or both mounting posts 1122 can have mounting holes 1121 at their tops. Clearly, the first electrode 21 and the second electrode 22 can also be installed in the first mounting groove 11 by screwing, bonding, magnetic adsorption, or other methods.
[0056] like Figures 1 to 4 As shown, the ion emission electrode 3 includes a carbon brush 32, which is electrically connected to the negative high-voltage terminal of the power module. When energized, it can ionize air through the tip 221 of the carbon brush 32 to generate negative ions. In this way, when the ion generator is powered on, the plasma generating component 2 and the ion emission electrode 3 can cover the entire ion generator. Any air flowing through the ion generator can come into contact with at least one of the plasma generating component 2 and the two ion emission electrodes 3. Under the plasma field generated by the plasma generating component 2 or the discharge from the tip 221 of the ion emission electrode 3, a sufficient number of plasma and negative ions are generated, thereby better sterilizing the air flowing through it and the space it occupies, effectively improving the sterilization effect. Of course, the ion emission electrode 3 can also be a carbon rod, or a needle made of one or more metal materials selected from stainless steel, copper, aluminum, tungsten, and molybdenum.
[0057] The ion emission electrode 3 includes a substrate 31 and a carbon brush 32 disposed on the substrate 31. The substrate 31 is generally cylindrical, and the carbon brush 32 is disposed at the end of the substrate 31. The mounting base 12 on the housing 1 is recessed inward from the upper side of the housing 1 and is generally cylindrical, with a through hole 121 at its bottom. The height of the mounting base 12 is approximately the same as the height of the substrate 31 of the ion emission electrode 3. During installation, the ion emission electrode 3 is placed in the mounting base 12, and the electrical wire is connected to it and then passes through the through hole 121 to connect to the negative high voltage terminal of the power module. Of course, the substrate 31 can be disposed on the mounting base 12 by other possible methods such as screwing, bonding, or snap-fitting. Correspondingly, the mounting base 12 and the substrate 31 are respectively provided with structures corresponding to the connection methods such as screwing, bonding, and snap-fitting. The specific structures for realizing these connection methods all adopt structures common in the art and are not limited in this application.
[0058] In one possible implementation, the ion generating device of this application is positioned near the air inlet of the indoor unit of the wall-mounted air conditioner. When installed, the plasma generating component 2 and the ion emitting electrode 3 face the air inlet, while the ultraviolet light emitted by the sterilization light generating component 4 irradiates along the length of the evaporator. Thus, when the wall-mounted air conditioner is running, after indoor air enters the indoor unit, part of it is ionized by the plasma generating component 2 and the ion emitting electrode 3 to generate plasma and negative ions, and part is irradiated by ultraviolet light. Under the action of plasma, negative ions, and ultraviolet light, the air is thoroughly sterilized. Simultaneously, the ultraviolet light irradiation also sterilizes the surface of the evaporator, preventing bacterial growth and secondary air pollution. Obviously, when installed, the plasma generating component 2 and the ion emitting electrode 3 can also be positioned along the length of the indoor unit, with the sterilization light generating component 4 emitting ultraviolet light towards the evaporator. Of course, the ion generating device can also be positioned near the air outlet of the indoor unit, or at any possible location within the air duct between the air inlet and outlet of the indoor unit. Although the above example uses an ion generator installed on a wall-mounted air conditioner, it is clear that the ion generator can also be installed on other types of air conditioners such as cabinet air conditioners and central air conditioners, or other types of air handling equipment such as air purifiers and sterilizers, or other possible equipment.
[0059] In summary, in the preferred embodiment of this invention, by providing a plasma generating component 2 capable of generating plasma, an ion emitting electrode 3 capable of generating negative ions, and an ion emitting electrode 3 disposed on at least one side of the plasma generating component 2, sufficient plasma and negative ions can be generated by fully ionizing the air flowing through the ion generating device. These plasmas and negative ions not only sterilize the air flowing through it but also sterilize the space where the ion generating device is located, effectively increasing the sterilization range and improving the sterilization effect. By integrating the plasma generating component 2 and the ion emitting electrode 3 onto the housing 1, it is convenient for users to install it in any preset position, all of which can meet sterilization requirements. The sterilization light generating component 4 disposed on the side of the housing 1 allows for better sterilization under the combined action of plasma, negative ions, and sterilization light, resulting in a better sterilization effect.
