DETAILED DESCRIPTION

[0056] like Figure 1 As shown, Figure 1 The structure of an air treatment device 200 in this embodiment is shown. The air treatment device 200 includes the structure of an air purification device 100 .

[0057] like Figure 2 , 3 As shown, the air purification device 100 includes a housing 2, a light emitting part 3 and an ion generating assembly 1. The housing 2 is made of an insulating material, and the housing 2 can be made of plastic. The light emitting part 3 and the ion generating assembly 1 are both arranged on the housing 2, and the housing 2 supports the light emitting part 3 and the ion generating assembly 1.

[0058] The ion generating assembly 1 can ionize the air to generate negative ions and / or plasma, and the negative ions and / or plasma are used to purify the air. The ion generating assembly 1 can ionize the air to generate negative ions, and the negative ions combine with positively charged particles such as bacteria, viruses, and dust in the air to make them condense and settle, thereby achieving the purpose of reducing the fine particles such as bacteria, viruses, and dust in the air. The negative ions have a long diffusion distance and a large range of action. The ion generating assembly 1 can also ionize the air to generate plasma, generating a large number of high-energy particles such as electrons, hydroxyl radicals, reactive oxygen species (ROS), and reactive nitrogen species (RNS). The high-energy particles can not only have a good killing effect on bacteria and viruses passing through the plasma area, but also have a good decomposition and purification effect on odors in the air.

[0059] The light emitting unit 3 includes a lamp bead (not shown in the figure). The lamp bead can be a light emitting diode. The lamp bead is configured to emit light when the ion generating assembly 1 ionizes the air. For example, the control switch of the lamp bead is linked with the control switch of the ion generating assembly 1, and the control switch of the ion generating assembly 1 and the switch of the lamp bead are started and closed synchronously.

[0060] In this way, the light-emitting part 3 can be used as an indicator light to indicate whether the ion generating component 1 is working. When the ion generating component 1 ionizes the air, the light-emitting part 3 will be lit and emit light. When the user sees that the light-emitting part 3 emits light, he can determine that the air purification device 100 has been turned on; when the ion generating component 1 stops ionizing the air, the light-emitting part 3 will be extinguished. When the user sees that the light-emitting part 3 does not emit light, he can determine that the air purification device 100 has not been turned on. Therefore, the user only needs to see whether the light-emitting part 3 emits light to determine whether the air purification device 100 is turned on, which is more convenient. At the same time, when the light-emitting part 3 emits light, the air purification device 100 is easier to be perceived by the user, thereby improving the user experience.

[0061] In an illustrative embodiment, Figures 3 to 5 As shown, the housing 2 includes a base 21 and a bottom cover 22. Figure 5 As shown, an inner cavity 210 is provided in the base 21. The base 21 can be constructed as a box body with an opening at the lower end. The bottom cover 22 can be constructed as a rectangular plate. The bottom cover 22 covers the opening of the base 21. The base 21 and the bottom cover 22 can be connected by snap-fit ​​connection, screw connection or ultrasonic welding. A light-transmitting hole 211 is provided on the wall surface of the inner cavity 210, and the light-transmitting hole 211 is a through hole. The light-transmitting hole 211 can be provided on the top wall of the inner cavity 210 facing away from the bottom cover 22, and the light-transmitting hole 211 vertically penetrates the top wall.

[0062] The light emitting part 3 is accommodated in the inner cavity 210 of the base 21. The lamp bead of the light emitting part 3 is located at one end of the light transmission hole 211 close to the inner cavity 210. The lamp bead emits light toward the light transmission hole 211.

[0063] The ion generating assembly 1 is connected to the base 21. The area where the ion generating assembly 1 ionizes the air is arranged outside the base 21, and the ion generating assembly 1 ionizes the air outside the base 21 to generate negative ions and / or plasma.

[0064] The light-emitting part 3 is contained in the inner cavity 210. When the lamp bead emits light, the light can be transmitted through the light-transmitting hole 211. The light can be directly irradiated in front of the light-transmitting hole 211, and most other areas will not be directly irradiated by the light. In this way, when the user views the air purification device 100 in the area other than in front of the light-transmitting hole 211, the light they see will be softer, and the user experience will be better. At the same time, a higher voltage is usually required to be loaded on the ion generating component 1 to ionize the air, and the ion generating component 1 ionizes the air outside the base 21, and the high-voltage electric field generated by the ion generating component 1 will not cause damage to the light-emitting part 3.

[0065] In an exemplary embodiment, the light-transmitting hole 211 on the base 21 is configured as a strip-shaped hole. The cross section of the light-transmitting hole 211 is strip-shaped.

[0066] The light-emitting part 3 includes a base and a plurality of lamp beads. The base can be configured as a strip. The plurality of lamp beads are arranged in sequence on the strip-shaped base. The light-emitting part 3 can be a light strip. The base is fixed on the base 21. The base and the base 21 can be bonded, clamped or screwed. The plurality of lamp beads are arranged in sequence at one end of the light-transmitting hole 211 close to the inner cavity 210 and along the extension direction of the cross section of the light-transmitting hole 211. The plurality of lamp beads emit light at the same time, the light intensity is greater, and it is more beautiful and conspicuous.

[0067] In an illustrative embodiment, Figure 6 As shown, the housing 2 further includes a support 23. The support 23 extends from a side of the base 21 where the light-transmitting hole 211 is provided in a direction away from the inner cavity 210 of the base 21. The support 23 and the base 21 may be an integrally formed structure. The support 23 is configured as a columnar structure. The support 23 is made of insulating material.

[0068] The ion generating assembly 1 includes a first electrode 11 and a second electrode 12. The first electrode 11 is disposed on and connected to the base 21. The first electrode 11 is located on one side of the light-transmitting hole 211. The second electrode 12 is connected to the support 23. The second electrode 12 may be connected to one end of the support 23 facing away from the base 21. The second electrode 12 and the support 23 may be snap-fit ​​connected.

[0069] The first electrode 11 and the second electrode 12 are both conductors. The first electrode 11 and / or the second electrode 12 may be made of metal, and the metal includes one or more of stainless steel, copper, aluminum, tungsten, and molybdenum. The first electrode 11 and / or the second electrode 12 may also be made of conductive non-metallic materials such as graphite and carbon fiber. The first electrode 11 and the second electrode 12 may include a strip-shaped, ring-shaped, or sheet-shaped conductive body, and the shapes of the first electrode 11 and the second electrode 12 are not limited.

[0070] The support 23 supports the second electrode 12 so that there is a gap between the first electrode 11 and the second electrode 12. The first electrode 11 is used to load a negative voltage, and the second electrode 12 is used to connect to the reference ground, so that there is a voltage difference between the first electrode 11 and the second electrode 12. The negative voltage loaded on the first electrode 11 can be -2kV to -10kV. When the voltage difference between the first electrode 11 and the second electrode 12 is large enough, the air between the first electrode 11 and the second electrode 12 is ionized to generate plasma, generating a large number of electrons, hydroxyl radicals, reactive oxygen species (ROS), reactive nitrogen species (RNS) and other high-energy particles, which can remove bacteria and odor. At the same time, the light-emitting portion 3 emits light when the first electrode 11 and the second electrode 12 generate plasma. The first electrode 11 and the second electrode 12 are located outside the base 21 in the area of ​​ionized air, and the plasma and the high-voltage electric field will not cause damage to the light-emitting portion 3.

[0071] In an exemplary embodiment, the housing 2 further includes a protective cover 25. The protective cover 25 covers the top wall of the base 21. The protective cover 25 covers an end of the light-transmitting hole 211 of the base 21 that faces away from the inner cavity 210 of the base 21.

[0072] The protective cover 25 is provided with a light-emitting through hole 251. A plurality of light-emitting through holes 251 can be provided. The light-emitting through holes 251 can allow light to pass through, and when the light is emitted into the protective cover 25 from the light-transmitting hole 211, it can be emitted from the protective cover 25 through the light-emitting through holes 251. The light-emitting through holes 251 can also allow air and active substances such as ions, electrons, and free radicals to enter or leave the protective cover 25. The protective cover 25 can be constructed as a hollow structure, and the hollow structure can be a grille, a screen, or other hollow structures, and the through holes formed by the hollow structure constitute the light-emitting through holes 251. The protective cover 25 can also be constructed as an arched plate. The air inside the protective cover 25 and the air outside the protective cover 25 can realize convection through the light-emitting through holes 251, so that the active substances can diffuse to the outside of the protective cover 25 through the light-emitting through holes 251.

[0073] The first electrode 11 may extend from the base 21 into the protective cover 25. The second electrode 12 and the support 23 are both located in the protective cover 25. The protective cover 25 can prevent a human body from touching the first electrode 11 and the second electrode 12, thereby preventing the human body from being cut by the first electrode 11 or the second electrode 12, and also preventing a human body from being electrocuted after contacting the first electrode 11 or the second electrode 12.

[0074] In an exemplary embodiment, the inner surface of the protective cover 25 is a mirror surface. When light enters the protective cover 25 from the light-transmitting hole 211, it can be reflected once or multiple times when it is directed to the inner surface of the protective cover 25 and then emitted from the protective cover 25 through the light-emitting through hole 251. The protective cover 25 hardly absorbs light, and the light emitted from the light-emitting through hole 251 is brighter.

[0075] In an illustrative embodiment, Figure 3 , 4 As shown, the first electrode 11 includes a conductive base 112 and a conductive tip portion 111. The conductive base 112 is disposed in the inner cavity 210 of the base 21 and is connected to the base 21. The conductive tip portion 111 is disposed on a side of the conductive base 112 close to the second electrode 12. A first mounting hole 212 is also disposed on the base 21. The first mounting hole 212 is disposed on one side of the light-transmitting hole 211. The conductive tip portion 111 extends from the conductive base 112 toward the second electrode 12, and the conductive tip portion 111 is penetrated through the first mounting hole 212 and extends into the protective cover 25. One end of the conductive tip portion 111 facing the second electrode 12 is a tip. The conductive tip portion 111 can be constructed as a structure with a small radius of curvature, such as a sawtooth shape, a needle shape, or a filament shape.

[0076] The light-emitting through hole 251 on the protective cover 25 includes a first light-emitting through hole 2511. The first light-emitting through hole 2511 may be disposed on the top of the protective cover 25. The first light-emitting through hole 2511 is a through hole. The first light-emitting through hole 2511 is located on the side of the second electrode 12 facing away from the first electrode 11.

[0077] The second electrode 12 is constructed as a flat plate. One plate surface of the second electrode 12 faces the first electrode 11, and the other plate surface of the second electrode 12 faces the first light-emitting through hole 2511. The second electrode 12 is provided with a spray hole 121. The spray hole 121 is a through hole. The spray hole 121 is located between the first light-emitting through hole 2511 and the conductive tip portion 111. One end of the spray hole 121 faces the conductive tip portion 111 of the first electrode 11, and the other end of the spray hole 121 faces the first light-emitting through hole 2511 of the protective cover 25. The spray hole 121 can be a centrally symmetrical shape such as a circle, a square, or a hexagon. The tip of the conductive tip portion 111 can be located on the central axis of the spray hole 121.

[0078] After such arrangement, the high-energy particles generated by the discharge of the first electrode 11 to the second electrode 12 are emitted in a beam shape toward the injection hole 121 of the second electrode 12, and are ejected out of the air purification device 100 through the injection hole 121 of the second electrode 12 and the first light-emitting through hole 2511 of the protective cover 25 in turn, thereby increasing the diffusion range of the high-energy particles and improving the sterilization and deodorization effects.

[0079] In an exemplary embodiment, the second electrode 12 is configured as a straight flat plate, with one surface of the second electrode 12 facing the first electrode 11 . A plurality of injection holes 121 are provided, and the plurality of injection holes 121 are sequentially arranged along the extension direction of the second electrode 12 .

[0080] The first light-emitting through hole 2511 on the protective cover 25 is configured as a strip-shaped hole. The plurality of injection holes 121 are aligned with the first light-emitting through hole 2511. The central axes of the plurality of injection holes 121 pass through the first light-emitting through hole 2511.

[0081] The conductive base 112 of the first electrode 11 is arranged in a straight strip shape. The extension direction of the conductive base 112 is the same as the extension direction of the cross section of the light-transmitting hole 211. The extension direction of the conductive base 112 is also parallel to the plate surface of the second electrode 12. The extension direction of the conductive base 112 of the first electrode 11 is also the same as the extension direction of the second electrode 12. A plurality of conductive tip portions 111 of the first electrode 11 are arranged. The number of conductive tip portions 111 of the first electrode 11 is the same as the number of injection holes 121.

[0082] An injection hole 121 is provided between each of the conductive tip portions 111 and the first light exiting through hole 2511. The tips of the plurality of conductive tip portions 111 may be located on the central axes of the plurality of injection holes 121, respectively.

[0083] The multiple conductive tip portions 111 discharge simultaneously, which generates more plasma and has better sterilization and deodorization effects.

[0084] In another exemplary embodiment, the second electrode 12 is provided with a spray hole 121 extending along the first direction, and the spray hole 121 may be a long strip-shaped hole. The first electrode 11 includes a conductive base 112 connected to the base 21 and a plurality of conductive tip portions 111 extending from the conductive base 112 toward the second electrode 12 and arranged along the first direction, and the conductive tip portions 111 are provided with a tip facing the spray hole 121, and at least two tips face the same spray hole 121. The protective cover 25 is provided with a first light-emitting through hole 2511 leading to the spray hole 121, and the first light-emitting through hole 2511 may extend along the first direction, and the first light-emitting through hole 2511 may be equal in length to the spray hole 121 in the first direction, and the first light-emitting through hole 2511 may be less than or equal to the width of the spray hole 121 in the width direction perpendicular to the first direction.

[0085] In an illustrative embodiment, Figure 6 As shown, the base 21 is provided with a first through hole 213. The first through hole 213 on the base 21 is provided between the pillar 23 and the first electrode 11. The first through hole 213 can be provided as a strip hole, and the extension direction of the cross section of the first through hole 213 is perpendicular to the direction from the pillar 23 to the first electrode 11. The length of the cross section of the first through hole 213 in its extension direction is preferably greater than or equal to the width of the pillar 23.

[0086] Since a first through hole 213 is provided between the pillar 23 and the first electrode 11, the water film formed on the surface of the pillar 23 and the base 21 in a high humidity environment is disconnected at the first through hole 213, which can effectively increase the creepage distance between the first electrode 11 and the second electrode 12 in a high humidity environment, and prevent the water film covering the pillar 23 and the base 21 from becoming an extension of the first electrode 11 and the second electrode 12 in a high humidity environment, thereby preventing arcing and sparking caused by a reduction in the discharge distance between the first electrode 11 and the second electrode 12.

[0087] In an exemplary embodiment, the width of the first through hole 213 of the base 21 in the direction from the pillar 23 to the first electrode 11 is greater than or equal to.

[0088] The width of the first through hole 213 is set to be greater than or equal to 1 mm, so that the creepage distance between the first electrode 11 and the second electrode 12 is sufficiently large in a high humidity environment, thereby further avoiding arcing between the first electrode 11 and the second electrode 12 .

[0089] In an illustrative embodiment, two pillars 23 are provided, and the two pillars 23 are spaced apart. The two pillars 23 are respectively connected to opposite ends of the second electrode 12. The two pillars 23 jointly support the second electrode 12. The first electrode 11 is disposed in the region between the two pillars 23. The opposite ends of the first electrode 11 are respectively oriented toward the two pillars 23. The two pillars 23 are spaced apart from the first electrode 11. The base 21 is provided with a first through hole 213 in the region between the first electrode 11 and each pillar 23.

[0090] The second electrode 12 is connected to the base 21 through two pillars 23, and the second electrode 12 is installed more firmly. At the same time, a first through hole 213 is provided between each pillar 23 and the first electrode 11, which can increase the creepage distance between the first electrode 11 and the second electrode 12 and prevent arcing and sparking.

[0091] In an illustrative embodiment, an insulating layer (not shown) is covered on the surface of the second electrode 12. The insulating layer covers the second electrode 12. The insulating layer can be an insulating paint coating, a plastic film layer, a silicone film layer or a ceramic film layer.

[0092] Since the insulating layer completely covers the second electrode 12, the insulating layer can completely isolate the second electrode 12 from the water film, and can completely prevent arcing and sparking between the first electrode 11 and the second electrode 12. In some embodiments, the surface of the second electrode 12 facing the first electrode 11 is exposed; or the second electrode 12 is provided with an insulating layer, and the insulating layer covers the surface of the second electrode 12 facing the first electrode 11.

[0093] In this way, the insulating layer may also partially cover the second electrode 12 , thereby reducing the probability of arcing and sparking between the first electrode 11 and the second electrode 12 .

[0094] In an illustrative embodiment, the ion generating assembly 1 further includes a third electrode 13. The third electrode 13 is a conductor. The third electrode 13 may be made of metal, and the metal may include one or more of stainless steel, copper, aluminum, tungsten, and molybdenum. The third electrode 13 may also be constructed as a carbon fiber bundle. The negative voltage loaded on the third electrode 13 may be -2kV to -10kV. The third electrode 13 is arranged outside the area between the first electrode 11 and the second electrode 12. The third electrode 13 may be arranged on one side of the first electrode 11 and spaced apart from the first electrode 11. The third electrode 13 is also spaced apart from the second electrode 12, and the distance between the second electrode 12 and the third electrode 13 is greater than or equal to 10mm. The distance between the third electrode 13 and the second electrode 12 is greater than the distance between the first electrode 11 and the second electrode 12. A negative voltage is loaded on the third electrode 13, and the third electrode 13 is configured to ionize the air to generate negative ions.

[0095] The negative ions generated by the third electrode 13 combine with positively charged particles such as bacteria, viruses, and dust in the air to cause them to condense and settle, thereby achieving the purpose of reducing fine particles such as bacteria, viruses, and dust in the air. The negative ions have a long diffusion distance and a large range of action; while the first electrode 11 and the second electrode 12 generate plasma to generate high-energy particles, which can not only have a good killing effect on bacteria and viruses passing through the plasma area, but also have a good decomposition and purification effect on odors in the air, but these high-energy particles are highly active, short-lived, and have a limited range of action. As a result, the plasma generated by the first electrode 11 and the second electrode 12 complements the negative ions generated by the third electrode 13, so that the air purification device 100 can not only diffuse negative ions into the air to play a large-scale sterilization role, but also kill bacteria and viruses in the air passing through the air purification device 100 through plasma, and at the same time have a deodorizing effect, so that the air can be purified and improved indoor air quality.

[0096] There is a voltage difference between the second electrode 12 and the third electrode 13, and an electric field is generated between the second electrode 12 and the third electrode 13. Because the distance between the second electrode 12 and the third electrode 13 is greater than or equal to 10 mm, the electric field can be greatly weakened. When a person touches the third electrode 13, the microcurrent passing through the human body will be smaller than the minimum value of the current that makes the human body feel an electric shock, so that the human body does not feel the electric shock, thereby improving the user experience.

[0097] In an exemplary embodiment, the distance between the second electrode 12 and the third electrode 13 is greater than or equal to 17 mm.

[0098] The distance between the second electrode 12 and the third electrode 13 is greater than or equal to 17 mm, which can avoid mutual interference between the electric field generated between the first electrode 11 and the second electrode 12 and the electric field generated by the third electrode 13 and reduce the generation rate of plasma and negative ions.

[0099] In an exemplary embodiment, the distance between the first electrode 11 and the second electrode 12 is less than or equal to 5.9 mm.

[0100] In this way, the distance between the first electrode 11 and the second electrode 12 is small, and the electric field strength between the first electrode 11 and the second electrode 12 is large, which can increase the discharge cavity between the first electrode 11 and the second electrode 12, thereby increasing the amount of plasma, so that the sterilization efficiency is further improved.

[0101] In an illustrative embodiment, a negative high voltage of -6.5 kV is applied to the first electrode 11, a negative high voltage of -6.5 kV is applied to the third electrode 13, and the second electrode 12 is grounded. The spacing between the first electrode 11 and the second electrode 12 is 5.9 mm, and the spacing between the third electrode 13 and the second electrode 12 is 17.4 mm. The air purification device 100 can achieve a sterilization rate of 99.9% in just one hour indoors, while the existing air purification device 100 usually takes two hours to achieve a sterilization rate of 99.9% under the same conditions.

[0102] In an illustrative embodiment, Figure 3 As shown, the housing 2 further includes a cylinder 24. The cylinder 24 extends from the base 21 to the second electrode 12. The cylinder 24 is also connected to the inner cavity 210 of the base 21. The cylinder 24 is used for the ground wire to pass through. The ground wire extends from the inner cavity 210 into the cylinder 24 and extends to the second electrode 12, and is connected to the second electrode 12.

[0103] The ground wire can be more beautiful when it is routed through the barrel 24 . Meanwhile, the barrel 24 can also protect the ground wire and weaken the electric field between the ground wire and the first electrode 11 .

[0104] In an illustrative embodiment, a mounting seat 214 is provided on the base 21. The mounting seat 214 is connected to the base 21 and is located outside the protective cover 25. The mounting seat 214 may be connected to a side of the base 21 close to the second electrode 12. The third electrode 13 is provided on the mounting seat 214. The mounting seat 214 may be provided with a second mounting hole, and the third electrode 13 is inserted into the second mounting hole of the mounting seat 214. The third electrode 13 is located outside the protective cover 25.

[0105] The third electrode 13 is arranged outside the protective cover 25 to prevent the third electrode 13 from being covered by the protective cover 25. The negative ions generated by the third electrode 13 ionizing the air diffuse onto the protective cover 25, causing negative charges to accumulate on the protective cover 25 to form a reverse electric field, resulting in a decrease in the rate at which the third electrode 13 generates negative ions.

[0106] In an exemplary embodiment, the base 21 is configured as a strip structure. A plurality of third electrodes 13 are provided. Two third electrodes 13 may be provided, and the two third electrodes 13 are respectively provided at opposite ends of the base 21. The protective cover 25 is located between the two third electrodes 13.

[0107] The plurality of third electrodes 13 are all disposed outside the protective cover 25 , and the plurality of third electrodes 13 generate more negative ions, which have a more significant effect on dust reduction and sterilization of the air.

[0108] In an illustrative embodiment, the air purification device 100 also includes a high-voltage power supply assembly. The high-voltage power supply assembly includes a high-voltage package and a plurality of wires. The high-voltage package includes a transformer, a rectifier electrically connected to the transformer, and an output port electrically connected to the rectifier. The transformer converts low-voltage alternating current into high-voltage alternating current and outputs it to the rectifier, and the rectifier converts high-voltage alternating current into high-voltage direct current. The output port includes a low-voltage output terminal and a high-voltage output terminal. High-voltage direct current is output to the outside through the low-voltage output terminal and the high-voltage output terminal. The low-voltage output terminal is electrically connected to the second electrode 12 through a wire. The high-voltage output terminal is electrically connected to the first electrode 11 and the third electrode 13 through a wire. Only one high-voltage output terminal can be set, and the high-voltage output terminal outputs the same negative high voltage to the first electrode 11 and the third electrode 13. Two high-voltage output terminals can also be set, one high-voltage output terminal is connected to the first electrode 11 through a wire, and the other high-voltage output terminal is connected to the third electrode through another wire. The two high-voltage output terminals can output negative high voltages with different voltages, so that the voltages of the negative high voltages loaded on the first electrode 11 and the third electrode 13 are different.

[0109] like Figure 1 As shown, the air treatment device 200 can take in and out air, and its air treatment function is not limited, for example, it can perform at least one of the air temperature adjustment, humidification, purification, circulation and other treatment functions. The air treatment device 200 includes but is not limited to an air conditioner, and the air treatment device 200 can also be a purifier, a humidifier, a fan, etc. After the specific type of the air treatment device 200 is determined, those skilled in the art can know the composition of the air treatment function implemented by the air treatment device 200, which will not be described in detail here.

[0110] The air treatment equipment 200 includes a housing 203, a fan and the above-mentioned air purification device 100. The housing 203 is provided with an air inlet, an air outlet 202 and an air duct 201. The two ends of the air duct 201 are respectively connected to the air inlet and the air outlet 202. The fan is arranged in the air duct 201. The fan can be a cross-flow fan or a centrifugal fan. After the fan is started, it can drive the air in the air duct 201 to move from the air inlet to the air outlet 202, so that the air inlet sucks the air in the surrounding environment into the air duct 201, and the air flows through the air duct 201 and then is discharged from the air outlet 202 to the surrounding environment. The air purification device 100 is arranged at the air inlet, in the air duct 201 or at the air outlet 202.

[0111] In an illustrative embodiment, the air purification device 100 is disposed in the air duct 201 , and the distance between the air purification device 100 and the air outlet 202 is no greater than 23 mm.

[0112] In this way, the distance between the air purification device 100 and the air outlet 202 is small, and the high-energy particles and negative ions generated by the air purification device 100 can enter the indoor space through the air outlet 202 as quickly as possible and diffuse in the indoor space, reducing the loss of high-energy particles and negative ions in the air duct 201, thereby further improving the sterilization efficiency of the indoor air.

[0113] In another embodiment, the light emitting portion 3 includes a fluorescent layer. The light emitting portion 3 does not have a lamp bead. The fluorescent layer is configured to be excited by the ions generated by the ion generating assembly 1 and emit light. The material of the fluorescent layer may include at least one of strontium titanate and zinc oxide. Both strontium titanate material and zinc oxide material can emit light when excited by ions. The fluorescent layer may be coated on the shell. The fluorescent layer may be coated on the base or on the inner wall of the protective cover.

[0114] When the ion generating assembly 1 ionizes the air, ions are generated, and a part of the ions (such as negative ions) can diffuse with the air to the fluorescent layer to excite the fluorescent layer to emit light, while the fluorescent layer will not be excited to emit light when the ion generating assembly 1 is not working. In this way, the user can judge whether the ion generating assembly 1 is working according to whether the fluorescent layer emits light.

[0115] At the same time, since the fluorescent layer does not need to be driven by a power source, there is no need to configure a power supply and a power supply line for the fluorescent layer, which can make the structure of the air purification device simpler and more energy-saving.

[0116] In an exemplary embodiment, the ion generating assembly 1 is connected to the base 21 and is disposed on one side of the base 21. The fluorescent layer is coated on the surface of the base 21 close to the ion generating assembly 1.

[0117] The fluorescent layer is coated on the surface of the base 21 close to the ion generating component 1. When the ions generated by the ion generating component 1 ionizing the air diffuse into the fluorescent layer, the ion concentration near the fluorescent layer is relatively large. When the high concentration of ions excites the fluorescent layer, the light emitted by the fluorescent layer is relatively strong, and the light emitted by the fluorescent layer is relatively obvious even in the daytime.
