[0002] Air handling equipment, with air conditioners as a typical example, is widely used in residential, commercial, industrial, and medical fields. Furthermore, as people's demands for indoor air quality increase, air conditioners have evolved from simple temperature control to a combination of temperature control and purification functions. Traditional air conditioners rely on filters to remove particulate matter, which suffers from problems such as easy clogging, the need for regular replacement of consumables, and limited ability to handle fine particles like PM2.5 and odors, making it difficult to meet user needs.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: Traditional filters have poor filtration and deodorization effects.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0021] Combination Figure 1-15 As shown, this disclosure provides an air treatment device including an ion module 200.

[0022] In some embodiments, such as Figure 1 As shown, the ion module 200 includes an air inlet electrode 210 and a filter electrode 220. The air inlet electrode 210 is connected to the negative terminal of the power supply device 270. The filter electrode 220 is spaced apart on one side of the air inlet electrode 210 and is connected to the positive terminal of the power supply device 270, or to the neutral wire of the power supply device 270, or to the ground wire of the power supply device 270.

[0023] In this embodiment, when the air inlet electrode 210 is connected to the negative electrode and the filter electrode 220 is connected to the positive electrode, the ion module 200 can function as a plasma device. In this case, a high-intensity electric field is formed between the air inlet electrode 210 and the filter electrode 220. This high-intensity electric field ionizes the gas to generate plasma (including positive ions, negative ions, and free radicals), which deodorizes and sterilizes the flowing air. When the air inlet electrode 210 is connected to the negative electrode and the filter electrode 220 is connected to the neutral or ground wire, the ion module 200 can function as a negative ion device. In this case, a low-intensity electric field is formed between the air inlet electrode 210 and the filter electrode 220. This low-intensity electric field ionizes the air to generate negative ions, which then adsorb pollutant particles from the flowing air. Thus, the ion module 200 can function as both a plasma device for deodorization and sterilization and a negative ion device for adsorbing pollutant particles, thereby meeting the needs of different application scenarios.

[0024] Optionally, the ion module 200 also includes a protective section 230, which is used to protect the air inlet electrode 210, thereby preventing accidental contact or electrode short circuit.

[0025] Optionally, such as Figure 1 As shown, the protective section 230 includes a protective grille 231, which is disposed on the side of the air inlet section 210 away from the filter section 220. The protective grille 231, while blocking foreign objects, facilitates the smooth passage of airflow.

[0026] Optionally, the ion module 200 also includes a mounting section 240 for mounting the air inlet electrode 210 and the filter electrode 220. In this way, the air inlet electrode 210 and the filter electrode 220 can be connected as a whole through the mounting section 240, thereby improving the modular design.

[0027] Optionally, such as Figure 1 As shown, the mounting part 240 includes a mounting frame 241, which is disposed between the air inlet electrode 210 and the filter electrode 220. The mounting frame 241 includes a first frame surface 2411 facing the air inlet electrode 210 and a second frame surface 2412 facing the filter electrode 220. The first frame surface 2411 is used to mount the air inlet electrode 210, and the second frame surface 2412 is used to mount the filter electrode 220. In this embodiment, the air inlet electrode 210 and the filter electrode 220 are typically thin and lightweight structures, and are easily deformed by external forces when fixed separately. Mounting them on two separate frame surfaces helps to improve the structural strength of the ion module 200.

[0028] Optionally, the mounting part 240 further includes a mounting plate 250, which is disposed on the side of the filter screen electrode 220 away from the air inlet electrode 210, for pressing the filter screen electrode 220 onto the second frame surface 2412. This improves the installation stability of the filter screen electrode 220.

[0029] Optionally, such as Figure 2 As shown, the air inlet electrode 210 includes a needle-shaped electrode 212 or a filamentous electrode. The needle tip of the needle-shaped electrode 212 and the elongated surface of the filamentous electrode can both generate an effective electric field.

[0030] Optionally, such as Figure 3 As shown, the filter electrode 220 is constructed as a mesh structure. When air flowing through the electric field passes through the mesh structure, the airflow distribution can be optimized, avoiding the impact of local airflow turbulence on ionization stability.

[0031] In some embodiments, the ion module 200 includes an air inlet electrode 210 and a filter electrode 220. The air inlet electrode 210 is connected to the negative terminal of the power supply device 270. The filter electrode 220 is spaced apart on one side of the air inlet electrode 210 and is connected to the positive terminal, neutral wire, or ground wire of the power supply device 270. The distance between the air inlet electrode 210 and the filter electrode 220 is d1, and 3mm ≤ d1 ≤ 20mm. To more clearly illustrate the distance between them, in... Figure 4 The exploded view illustrates d1.

[0032] In this embodiment, the type of ions generated by the ion module 200 can be controlled by adjusting the connection relationship between the filter electrode 220 and the power supply device 270. The ion module 200 can function as both a plasma device for deodorization and sterilization, and a negative ion device for adsorbing pollutant particles, thus meeting different application scenarios. Since the core function of the ion module 200 depends on the electric field strength between the air inlet electrode 210 and the filter electrode 220, and the electric field strength is inversely proportional to the distance (under the same voltage, the smaller the distance, the stronger the electric field), setting the distance d1 between the air inlet electrode 210 and the filter electrode 220 within the range of 3mm ≤ d1 ≤ 20mm can match the electric field strength requirements of the two functional modes.

[0033] Optionally, 3mm ≤ d1 ≤ 10mm. When d1 is within this smaller spacing range, it is beneficial to form a higher intensity electric field so that the ion module 200 can function as a plasma device.

[0034] Optionally, 10mm ≤ d1 ≤ 20mm. When d1 is within this larger spacing range, it is beneficial to form a lower intensity electric field so that the ion module 200 can function as a negative ion device.

[0035] Optionally, the value of d1 can be 3mm, 5mm, 7mm, 9mm, 10mm, 12mm, 14mm, 16mm, 18mm or 20mm.

[0036] Optionally, the plane containing the air inlet electrode 210 is parallel to the plane containing the filter electrode 220. This helps to enhance the stability of the electric field formed between the two.

[0037] Optionally, the ion module 200 further includes a mounting frame 241, which includes a first frame surface 2411 and a second frame surface 2412 facing each other. The air inlet electrode 210 is disposed on the first frame surface 2411, and the filter electrode 220 is disposed on the second frame surface 2412. In this embodiment, the air inlet electrode 210 and the filter electrode 220 are typically thin and lightweight structures, and are easily deformed by external forces when fixed separately. Mounting them on two separate frame surfaces helps improve the structural strength of the ion module 200.

[0038] Optionally, such as Figure 2 As shown, the air inlet electrode 210 includes a connecting frame 211 and needle-shaped electrodes 212. The needle-shaped electrodes 212 are disposed on the edge of the connecting frame 211, and the extension direction of the needle tip is parallel to the plane on which the connecting frame 211 is located. In this way, multiple needle-shaped electrodes 212 are arranged on the connecting frame 211, and the power supply device 270 can supply power to all needle-shaped electrodes 212 through the connecting frame 211.

[0039] Optionally, such as Figure 5As shown, a first groove 242 is provided on the first frame surface 2411, and the first groove 242 corresponds to the connecting frame 211. Specifically, in a direction perpendicular to the first frame surface 2411, the connecting frame 211 is partially or completely embedded in the first groove 242. Thus, the first groove 242 provides an installation position for the connecting frame 211.

[0040] Optionally, such as Figure 5 As shown, a first clearance opening 2421 is provided on the side wall of the first groove 242. The first clearance opening 2421 corresponds to the needle-shaped electrode 212, and the tip of the needle-shaped electrode 212 extends outward through the first clearance opening 2421. In this way, structural interference can be avoided and the layout of the needle-shaped electrode 212 can be optimized.

[0041] In some embodiments, the ion module 200 includes an air inlet electrode 210, a filter electrode 220, and a protective part 230. The air inlet electrode 210 is connected to the negative terminal of the power supply device 270. The filter electrode 220 is spaced apart on one side of the air inlet electrode 210 and is connected to the positive terminal, neutral wire, or ground wire of the power supply device 270. The protective part 230 is disposed on the side of the air inlet electrode 210 away from the filter electrode 220 and is used to protect the air inlet electrode 210. The distance between the air inlet electrode 210 and the protective part 230 is d2, and 3mm ≤ d2 ≤ 15mm. To more clearly illustrate the distance between them, ... Figure 4 The exploded view illustrates d2.

[0042] In this embodiment, the type of ions generated by the ion module 200 can be controlled by adjusting the connection relationship between the filter electrode 220 and the power supply device 270. The ion module 200 can function as both a plasma device for deodorization and sterilization, and a negative ion device for adsorbing pollutant particles, thus meeting the needs of different application scenarios. Furthermore, setting the distance d2 between the air inlet electrode 210 and the protective part 230 within the range of 3mm ≤ d2 ≤ 15mm provides both effective protection and ensures smooth airflow.

[0043] Optionally, 3mm≤d2≤10mm. This results in a relatively small distance between the air inlet section 210 and the protective section 230, making it suitable for scenarios with limited installation space.

[0044] Optionally, 10mm≤d2≤15mm. This results in a relatively large distance between the air inlet section 210 and the protective section 230, making it suitable for installation scenarios with ample space.

[0045] Optionally, the value of d1 can be 3mm, 5mm, 7mm, 9mm, 10mm, 12mm, 14mm or 15mm.

[0046] Optionally, the protective part 230 includes a protective grille 231, which includes a first grille surface 2311 and a second grille surface 2312. The first grille surface 2311 faces the air inlet pole 210. The second grille surface 2312 is disposed opposite to the first grille surface 2311 and is provided with a grid structure. The distance between the air inlet pole 210 and the second grille surface 2312 is d2. In this way, the grid structure can effectively prevent foreign objects from entering and facilitate smooth airflow.

[0047] Optionally, the air inlet electrode 210 includes a connecting frame 211 and needle-shaped electrodes 212. The needle-shaped electrodes 212 are disposed on the edge of the connecting frame 211, and the extension direction of the needle tip is parallel to the plane on which the connecting frame 211 is located. In this way, multiple needle-shaped electrodes 212 are arranged on the connecting frame 211, and the power supply device 270 can supply power to all needle-shaped electrodes 212 through the connecting frame 211.

[0048] Optionally, such as Figure 6 As shown, a second groove 232 is provided on the first grid surface 2311, and the second groove 232 corresponds to the connecting frame 211. Specifically, in a direction perpendicular to the first grid surface 2311, the connecting frame 211 is partially or completely embedded in the second groove 232. Thus, the second groove 232 provides an installation position for the connecting frame 211.

[0049] Optionally, a second clearance opening 2321 is provided on the side wall of the second groove 232, the second clearance opening 2321 corresponding to the needle electrode 212, and the needle tip of the needle electrode 212 extends outward through the second clearance opening 2321. In this way, structural interference can be avoided and the layout of the needle electrode 212 can be optimized.

[0050] Optionally, the inner contour of the second clearance opening 2321 abuts against the outer contour of the needle electrode 212. This helps to prevent the needle electrode 212 from shaking.

[0051] Optionally, when the first frame surface 2411 has a first groove 242 and the first grid surface 2311 has a second groove 232, the mounting frame 241 and the protective grid 231 are connected, the first frame surface 2411 and the first grid surface 2311 are abutted, and the first groove 242 and the second groove 232 are engaged. Specifically, in the thickness direction of the connecting frame 211, a portion of the connecting frame 211 is located within the first groove 242, and another portion is located within the second groove 232. In the thickness direction of the needle electrode 212, a portion of the needle electrode 212 is located within the first clearance opening 2421, and another portion is located within the second clearance opening 2321.

[0052] In some embodiments, the ion module 200 includes an air inlet electrode 210 and a filter electrode 220. The air inlet electrode 210 is connected to the negative terminal of the power supply device 270. The filter electrode 220 is spaced apart on one side of the air inlet electrode 210 and is connected to the positive terminal, neutral wire, or ground wire of the power supply device 270. Figure 3 As shown, the filter pole 220 is constructed as a mesh structure. The mesh number of the filter pole 220 is m, then 20 mesh ≤ m ≤ 60 mesh.

[0053] In this embodiment, the type of ions generated by the ion module 200 can be controlled by adjusting the connection relationship between the filter electrode 220 and the power supply device 270. The ion module 200 can function as both a plasma device for deodorization and sterilization, and a negative ion device for adsorbing pollutant particles, thus meeting different application scenarios. The mesh count of the filter electrode 220 refers to the number of mesh openings per unit area; a lower mesh count indicates sparser pores, and a higher mesh count indicates denser pores. Whether it is plasma under a plasma device or negative ions under a negative ion device, both need to pass through the mesh openings of the filter electrode 220 and diffuse with the airflow. Limiting the mesh count of the filter electrode 220 to 20 mesh ≤ m ≤ 60 mesh ensures that a uniform high-intensity electric field is formed with the air inlet electrode 210 when connected to the positive electrode, and also facilitates the uniform diffusion of airflow containing negative ions or plasma, avoiding local airflow turbulence from affecting ionization stability.

[0054] Optionally, the mesh size should be 20 mesh ≤ m ≤ 30 mesh. In this way, the mesh size of the filter electrode 220 is relatively loose.

[0055] Optionally, the mesh size should be 30 mesh ≤ m ≤ 60 mesh. This results in a relatively denser mesh size at the filter electrode 220.

[0056] Optionally, the value of m can be 20 mesh, 25 mesh, 30 mesh, 35 mesh, 40 mesh, 45 mesh, 50 mesh, 55 mesh, or 60 mesh.

[0057] Optionally, the mesh shape of the filter electrode 220 is configured as circular, regular polygonal, or irregular. Here, circular or regular polygonal meshes experience more uniform stress compared to irregularly shaped meshes.

[0058] Alternatively, when the mesh shape of the filter electrode 220 is constructed as a regular polygon, the mesh shape of the filter electrode 220 includes rectangular or hexagonal shapes. Here, rectangular or hexagonal meshes are beneficial for uniform airflow diffusion.

[0059] Optionally, the mesh openings in the filter electrode portion 220 are configured as circular or regular polygonal. The air inlet electrode portion 210 includes a needle-shaped electrode 212, with the tip of the needle-shaped electrode 212 facing the filter electrode portion 220 and the center of the mesh opening shape. In this way, the extension direction of the needle tip is perpendicular to the plane where the connecting frame 211 is located, and the electric field of the needle tip diffuses radially. When the needle tip is aligned with the center of the mesh opening shape, it is beneficial for the electric field to uniformly cover the mesh opening, which in turn is beneficial for negative ions or plasma to diffuse uniformly through the mesh opening with the airflow.

[0060] Optionally, the ion module 200 further includes a mounting frame 241, which includes a first frame surface 2411 and a second frame surface 2412 facing each other. The air inlet electrode 210 is disposed on the first frame surface 2411, and the filter electrode 220 is disposed on the second frame surface 2412. In this embodiment, the air inlet electrode 210 and the filter electrode 220 are typically thin and lightweight structures, and are easily deformed by external forces when fixed separately. Mounting them on two separate frame surfaces helps improve the structural strength of the ion module 200.

[0061] Optionally, such as Figure 1 As shown, the ion module 200 also includes a mounting plate 250, which is disposed on the side of the filter electrode 220 away from the air inlet electrode 210, and is used to press the filter electrode 220 onto the second frame surface 2412. This improves the installation stability of the filter electrode 220.

[0062] In some embodiments, the air treatment device includes a housing 100 and an ion module 200 as described in any of the above embodiments. For example... Figure 7 As shown, the housing 100 has an air inlet 101, and a temperature regulating device 110 is installed inside it. The air inlet portion 210 and the filter portion 220 of the ion module 200 are disposed between the air inlet 101 and the temperature regulating device 110. Specifically, the air inlet portion 210 is closer to the air inlet 101, and the filter portion 220 is closer to the temperature regulating device 110. Thus, by applying the ion module 200 to air handling equipment, such as air conditioners, air purifiers, dehumidifiers, and fresh air systems 130, the air handling equipment can not only deodorize, sterilize, and adsorb pollutant particles, but also improve the defrosting effect of the temperature regulating device 110 in the self-cleaning mode of the air handling equipment.

[0063] Optionally, the housing 100 also includes an air outlet 102. The ion module 200 further includes an air outlet electrode 280, which is disposed at the air outlet 102 and connected to the negative terminal of the power supply 270. Under the action of the air outlet electrode 280, air can be ionized to generate negative ions, thereby neutralizing the positive ions in the flowing airflow, so that the ratio of positive and negative ions in the air blown out from the air outlet 102 reaches a relatively balanced level, meeting the user's health needs.

[0064] In some embodiments, the air handling unit includes a housing 100 and an ionization module 200. For example... Figure 7 As shown, the housing 100 has an air inlet 101, and a temperature regulating device 110 is installed inside it. The ion module 200 includes an air inlet electrode 210 and a filter electrode 220 disposed between the air inlet 101 and the temperature regulating device 110. The air inlet electrode 210 and the filter electrode 220 are spaced apart, with the air inlet electrode 210 closer to the air inlet 101 and the filter electrode 220 closer to the temperature regulating device 110. The air inlet electrode 210 is connected to the negative terminal of the power supply device 270, and the filter electrode 220 is connected to the positive terminal, neutral wire, or ground wire of the power supply device 270.

[0065] In this embodiment, air enters the housing 100 through the air inlet 101 and flows sequentially through the air inlet electrode 210, the filter electrode 220, and the temperature regulating device 110. When the air inlet electrode 210 is connected to the negative electrode and the filter electrode 220 is connected to the positive electrode, the ion module 200 functions as a plasma device. In this case, a high-intensity electric field is formed between the air inlet electrode 210 and the filter electrode 220. This high-intensity electric field ionizes the gas to generate plasma (including positive ions, negative ions, and free radicals), which deodorizes and sterilizes the airflow passing through the ion module 200. When the air inlet electrode 210 is connected to the negative electrode and the filter electrode 220 is connected to the neutral or ground wire, the ion module 200 functions as a negative ion device. In this case, a low-intensity electric field is formed between the air inlet electrode 210 and the filter electrode 220. This low-intensity electric field ionizes the air to generate negative ions, which then adsorb pollutant particles from the passing air. In this way, the ion module 200 can function as both a plasma device for deodorization and sterilization, and a negative ion device for adsorbing pollutant particles, thus meeting the needs of different application scenarios. Furthermore, in the self-cleaning mode of the air handling equipment, the ion module 200, acting as a negative ion device, can improve the condensation and frosting effects of the temperature control device 110, thereby cleaning the temperature control device 110 through defrosting. After the defrosting stage, the ion module 200, acting as a plasma device, can cause ions retained on the surface of the temperature control device 110 to move towards the air inlet electrode 210 under the influence of the potential difference, thus detaching from the temperature control device 110. This prevents the retained ions from corroding the organic coating on the surface of the temperature control device 110.

[0066] Optionally, the air handling unit includes an air conditioner, such as a wall-mounted or floor-standing air conditioner. The temperature control device 110 includes a heat exchanger 120.

[0067] Optionally, when the filter electrode 220 is connected to the neutral or ground wire of the power supply device 270, the ion module 200 generates negative ions. When the filter electrode 220 is connected to the positive terminal of the power supply device 270, the ion module 200 generates plasma. Furthermore, the mesh of the filter electrode 220 is used to uniformly distribute negative ions or plasma onto the temperature control device 110. In this way, the ion type can be controlled and the ions are uniformly distributed.

[0068] Optionally, the air handling unit includes a first cleaning mode. The first cleaning mode corresponds to the connection of the filter electrode 220 with the neutral or ground wire of the power supply unit 270, and is used to clean the filter electrode 220.

[0069] In this embodiment, the ion module 200 generates negative ions, and water molecules in the air combine with the negative ions to form hydrated negative ions. Since the filter electrode 220 is conductive and has a low potential, the hydrated negative ions can effectively adhere to the filter electrode 220 and condense into water droplets. The water droplets can then fall off under the influence of gravity, thus cleaning the filter electrode 220.

[0070] Optionally, the air handling equipment includes a first purification mode. The first purification mode corresponds to the filter electrode 220 being connected to the positive terminal of the power supply device 270, and is used to purify the air flowing through it. In this embodiment, the ion module 200 generates plasma, which deodorizes and sterilizes the airflow passing through the ion module 200.

[0071] Optionally, when the filter electrode 220 is connected to the positive terminal of the power supply device 270, when the airflow is small or there is no airflow, the potential difference generated by the ion module 200 can cause the ions retained on the surface of the temperature regulating device 110 to move toward the air inlet electrode 210 and thus detach from the temperature regulating device 110. This can prevent the retained ions from corroding the organic coating on the surface of the temperature regulating device 110.

[0072] Optionally, the temperature regulating device 110 is conductive and can be connected to the positive terminal, neutral wire, or ground wire of the power supply device 270. In this embodiment, the temperature regulating device 110 refers to a device capable of cooling and heating. Optionally, the temperature regulating device 110 includes a heat exchanger 120.

[0073] Optionally, when the temperature control device 110 is connected to a neutral or ground wire, an electric field for generating negative ions is formed between the air inlet electrode 210 and the temperature control device 110. When the temperature control device 110 is connected to a positive electrode, an electric field for generating plasma is formed between the air inlet electrode 210 and the temperature control device 110. Furthermore, the mesh of the filter electrode 220 is used to uniformly distribute negative ions or plasma onto the temperature control device 110. In this way, the ion type can be controlled and the ions are uniformly distributed.

[0074] Optionally, the air handling unit includes a second cleaning mode, which corresponds to the connection of the temperature control device 110 with the neutral or ground wire of the power supply device 270, for cleaning the temperature control device 110.

[0075] In this embodiment, an electric field generating negative ions is formed between the air inlet 210 and the temperature regulating device 110. Water molecules in the air combine with the negative ions to form hydrated negative ions. Hydrated negative ions are larger in size and have a stronger adsorption capacity than ordinary negative ions, enabling them to adsorb pollutants such as dust. Because the temperature regulating device 110 is at a low potential, the hydrated negative ions can effectively adhere to the temperature regulating device 110 and condense into water droplets (condensation). These water droplets can then fall off under gravity, thus cleaning the temperature regulating device 110. Furthermore, with the cooling of the temperature regulating device 110, the water droplets can condense into a frost layer, which can then be defrosted by heating the temperature regulating device 110. This cleaning mode, which includes at least condensation, frost formation, and defrosting, is also called a self-cleaning mode.

[0076] Optionally, the air handling unit includes a second purification mode. The second purification mode corresponds to the temperature control device 110 being connected to the positive terminal of the power supply device 270, and is used to purify the flowing air. In this embodiment, an electric field that generates plasma is formed between the air inlet 210 and the temperature control device 110, which deodorizes and sterilizes the flowing air.

[0077] In some embodiments, the air handling unit includes a housing 100 and an ionization module 200. The housing 100 has an air inlet 101 and a temperature control device 110 inside. Figure 7 As shown, the ion module 200 includes an air inlet electrode 210 and a filter electrode 220 disposed between the air inlet 101 and the temperature regulating device 110. The air inlet electrode 210 and the filter electrode 220 are spaced apart, with the air inlet electrode 210 closer to the air inlet 101 and the filter electrode 220 closer to the temperature regulating device 110. The air inlet electrode 210 is connected to the negative terminal of the power supply device 270, and the filter electrode 220 is connected to the positive terminal, neutral wire, or ground wire of the power supply device 270. The distance between the filter electrode 220 and the temperature regulating device 110 is d3, and 0mm ≤ d3 ≤ 10mm.

[0078] In this embodiment, air enters the housing 100 through the air inlet 101 and flows sequentially through the air inlet electrode 210, the filter electrode 220, and the temperature regulating device 110. By adjusting the connection between the filter electrode 220 and the power supply device 270, the type of ions generated by the ion module 200 can be controlled. The ion module 200 can function as a negative ion device to adsorb pollutant particles and improve the condensation and frosting effect of the temperature regulating device 110, and also as a plasma device to deodorize and sterilize, preventing corrosion of the organic coating on the surface of the temperature regulating device 110, thus meeting different application scenarios. Furthermore, setting the distance between the filter electrode 220 and the temperature regulating device 110 to 0mm≤d3≤10mm helps reduce the attenuation of ions during migration in the electric field, ensuring that ions effectively adhere to the surface of the temperature regulating device 110.

[0079] Optionally, 2mm≤d3≤8mm.

[0080] Optionally, 4mm≤d3≤6mm.

[0081] Optionally, the value of d3 can be 0mm, 2mm, 4mm, 6mm, 8mm or 10mm.

[0082] Optionally, the temperature regulating device 110 includes a heat exchanger 120, which includes a first heat exchange section 121, and the first heat exchange section 121 includes a first windward surface 1211. Furthermore, the filter screen electrode 220 is parallel to the first windward surface 1211, and d3 is the distance between the filter screen electrode 220 and the first windward surface 1211. In this embodiment, the first windward surface 1211 refers to the surface of the windward side of the first heat exchange section 121.

[0083] Optionally, the temperature regulating device 110 includes a heat exchanger 120, which includes a first heat exchange section 121, and the first heat exchange section 121 includes a first air-facing surface 1211. Furthermore, the filter screen electrode 220 is not parallel to the first air-facing surface 1211, and d3 is the maximum distance between the filter screen electrode 220 and the first air-facing surface 1211. In this embodiment, at least two points on the filter screen electrode 220 have different distances from the first air-facing surface 1211.

[0084] Optionally, the filter electrode 220 has a first end and a second end opposite to each other, with the first end facing the air inlet 101 and the second end away from the air inlet 101. For example... Figure 8 As shown, the distance between the first end and the first windward surface 1211 is d31, and the distance between the second end and the first windward surface 1211 is d32, where d31 < d32. In this embodiment, the filter pole portion 220 is located on a plane, and its first end is closer to the first windward surface 1211 than its second end.

[0085] Optionally, 0.2 ≤ d31 / d32 ≤ 0.8.

[0086] Optionally, 0.4 ≤ d31 / d32 ≤ 0.6.

[0087] Optionally, the values ​​of d31 / d32 can be 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 or 0.8.

[0088] Optionally, the housing 100 also includes an air outlet 102, and the ion module 200 further includes an air outlet electrode 280, which is located at the air outlet 102 and connected to the negative terminal of the power supply 270. Under the action of the air outlet electrode 280, air can be ionized to generate negative ions, thereby neutralizing the positive ions in the flowing airflow. This ensures that the ratio of positive to negative ions in the air blown out from the air outlet 102 reaches a relatively balanced level, meeting the user's health needs.

[0089] Optionally, the air outlet electrode 280 includes a needle electrode 212 or a wire electrode.

[0090] In some embodiments, the air handling unit includes a housing 100 and an ionization module 200. The housing 100 has an air inlet 101 and a temperature regulating device 110 inside. The ionization module 200 is disposed between the air inlet 101 and the temperature regulating device 110, and the ionization module 200 includes a mounting frame 241. Figure 9 As shown, the mounting frame 241 has first mounting members 243 at both ends of its first side and second mounting members 244 at both ends of its second side. The assembly assembly 260 includes two sliding grooves 261 corresponding to the two first mounting members 243, and two retaining members 262 corresponding to the two second mounting members 244. The sliding grooves 261 include a first groove position and a second groove position. When the first mounting member 243 moves along the sliding groove 261 to the first groove position and the second groove position respectively, the distance between the ion module 200 and the temperature regulating device 110 is different. The retaining members 262 are used to retain the mounting frame 241 after the first mounting member 243 moves to the first groove position or the second groove position.

[0091] In this embodiment, the mounting frame 241 of the ion module 200 is installed inside the housing 100 via a sliding groove 261 and a retaining member 262. During installation, the first mounting member 243 on the first side of the mounting frame 241 is first installed in the sliding groove 261 and slid to either the first groove position or the second groove position. Then, the retaining member 262 holds the second mounting member 244 on the second side of the mounting frame 241, thus completing the installation. In this way, the distance between the ion module 200 and the temperature regulating device 110 can be adjusted by changing the position of the first mounting member 243 within the sliding groove 261, thereby meeting different usage scenarios and installation requirements.

[0092] Optionally, such as Figure 9 and Figure 10 As shown, the slide rail 261 is constructed in an arc shape. In this way, the slide rail 261 forms a curved trajectory for movement adjustment.

[0093] Optionally, such as Figure 9 and Figure 10 As shown, the center of curvature of the slide 261 is oriented toward the temperature regulating device 110.

[0094] Optionally, such as Figure 9 As shown, the first end of the sliding part 261 is provided with an open slot 2611, and the first mounting part 243 enters the sliding part 261 through the open slot 2611. In this way, the open slot 2611 facilitates installation and disassembly.

[0095] Optionally, the first mounting member 243 is constructed in a cylindrical shape, and the diameter of the first mounting member 243 is adapted to the groove width of the slide member 261. This prevents the first mounting member 243 from getting stuck when moving within the slide member 261.

[0096] Optionally, such as Figure 9 As shown, the retaining member 262 includes a first retaining slot 2621 and a second retaining slot 2622. The first retaining slot 2621 can retain the second mounting member 244 when the first mounting member 243 moves to the first slot position. The second retaining slot 2622 can retain the second mounting member 244 when the first mounting member 243 moves to the second slot position. In this way, the position of the mounting frame 241 can be effectively fixed. Furthermore, the position of the retaining member 262 can be adjusted to correspond to the position of the sliding member 261.

[0097] Optionally, the second mounting member 244 is constructed as a cylinder, and the diameter of the second mounting member 244 is adapted to the groove width of the first slot 2621 and the groove width of the second slot 2622. This helps to improve the holding and fixing effect of the retaining member 262.

[0098] Optionally, when the first mounting component 243 is located in the first tank position and / or the second tank position, the ion module 200 is parallel to the temperature regulating device 110. This helps to save installation space.

[0099] Optionally, when the first mounting component 243 is located in the first tank position and / or the second tank position, the ion module 200 and the temperature regulating device 110 are not parallel, and the maximum distance between the ion module 200 and the temperature regulating device 110 is different. In this way, the appropriate distance can be adjusted according to design requirements if the installation space allows.

[0100] In some embodiments, the air handling equipment includes a housing 100 and a first ionization module 201. The housing 100 has an air inlet 101 and a temperature regulating device 110 inside it. The first ionization module 201 includes an air inlet electrode 210 and a filter electrode 220 disposed between the air inlet 101 and the temperature regulating device 110. The air inlet electrode 210 and the filter electrode 220 are spaced apart, with the air inlet electrode 210 closer to the air inlet 101 and the filter electrode 220 closer to the temperature regulating device 110. The air inlet electrode 210 is connected to the negative terminal of a power supply device 270, and the filter electrode 220 is connected to the positive terminal, neutral wire, or ground wire of the power supply device 270. The temperature regulating device 110 includes a first heat exchange section 121 having a first windward surface 1211, and a first projection of the filter electrode 220 is made in a direction perpendicular to the first windward surface 1211, the first projection partially or completely covering the first windward surface 1211.

[0101] In this embodiment, air enters the housing 100 through the air inlet 101 and flows sequentially through the air inlet electrode 210, the filter electrode 220, and the temperature regulating device 110. By adjusting the connection between the filter electrode 220 and the power supply device 270, the type of ions generated by the ion module 200 can be controlled. The ion module 200 can function as a negative ion device to adsorb pollutant particles and improve the condensation and frosting effect of the temperature regulating device 110, and also as a plasma device to deodorize and sterilize, preventing corrosion of the organic coating on the surface of the temperature regulating device 110, thus meeting different application scenarios. Since the air first contacts the first windward surface 1211 after flowing through the filter electrode 220, designing the first projection to partially or completely cover the first windward surface 1211 is beneficial for ions to adhere evenly to the first windward surface 1211.

[0102] Optionally, the area of ​​the first projection is s1, the area of ​​the first windward surface 1211 is s2, and 0.5≤s1 / s2≤1.

[0103] Optionally, 0.8 ≤ s1 / s2 ≤ 1.

[0104] Optionally, the value of s1 / s2 can be 0.5, 0.6, 0.7, 0.8, 0.9 or 1.

[0105] Optionally, such as Figure 11As shown, the air handling equipment also includes a second ion module 202 with the same structure as the first ion module 201. The temperature regulating device 110 also includes a second heat exchange section 122, which is obliquely connected to the lower end of the first heat exchange section 121. The second heat exchange section 122 includes a second air-facing surface 1221. The second ion module 202 corresponds to the second heat exchange section 122, and a second projection of the filter pole portion 220 of the second ion module 202 is made along a direction perpendicular to the second air-facing surface 1221. The second projection partially or completely covers the second air-facing surface 1221. In this way, the combination of the first heat exchange section 121 and the second heat exchange section 122 increases the heat exchange area, and by setting the second ion module 202, the flowing air can form hydrated negative ions and attach to the second heat exchange section 122, so as to facilitate the cleaning of the second heat exchange section 122.

[0106] Optionally, the area of ​​the second projection is s3, and the area of ​​the second windward surface 1221 is s4, where 0.5≤s3 / s4≤1.

[0107] Optionally, 0.8 ≤ s3 / s4 ≤ 1.

[0108] Optionally, the values ​​of s3 / s4 can be 0.5, 0.6, 0.7, 0.8, 0.9 or 1.

[0109] Optionally, such as Figure 11 As shown, the air handling equipment also includes a third ion module 203 with the same structure as the first ion module 201. The temperature regulating device 110 also includes a third heat exchange section 123, which is obliquely connected to the upper end of the first heat exchange section 121. The third heat exchange section 123 includes a third air-facing surface 1231. The third ion module 203 corresponds to the third heat exchange section 123, and a third projection of the filter pole portion 220 of the third ion module 203 is made along a direction perpendicular to the third air-facing surface 1231. The third projection partially or completely covers the third air-facing surface 1231. In this way, the combination of the first heat exchange section 121 and the third heat exchange section 123 increases the heat exchange area, and by setting the third ion module 203, the flowing air can form hydrated negative ions and attach to the third heat exchange section 123, so as to facilitate the cleaning of the third heat exchange section 123.

[0110] Optionally, the area of ​​the third projection is s5, the area of ​​the third windward surface 1231 is s6, and 0.5≤s5 / s6≤1.

[0111] Optionally, 0.8 ≤ s5 / s6 ≤ 1.

[0112] Optionally, the values ​​of s5 / s6 can be 0.5, 0.6, 0.7, 0.8, 0.9 or 1.

[0113] In some embodiments, the air handling unit includes a housing 100 and an ionization module 200. The housing 100 has an air inlet 101 and a temperature regulating device 110 inside. The ionization module 200 includes an air inlet electrode 210 and a filter electrode 220 disposed between the air inlet 101 and the temperature regulating device 110. The air inlet electrode 210 and the filter electrode 220 are spaced apart, with the air inlet electrode 210 near the air inlet 101 and connected to the negative terminal of a power supply device 270, and the filter electrode 220 near the temperature regulating device 110. Figure 11 As shown, the filter electrode 220 can move from a first moving position to a second moving position toward the temperature regulating device 110, wherein the first moving position corresponds to the filter electrode 220 being connected to the positive terminal of the power supply device 270, and the second moving position corresponds to the filter electrode 220 being connected to the neutral or ground wire of the power supply device 270.

[0114] In this embodiment, air enters the housing 100 through the air inlet 101 and flows sequentially through the air inlet electrode 210, the filter electrode 220, and the temperature regulating device 110. The filter electrode 220 is a movable component and has a first movable position and a second movable position. When the filter electrode 220 moves to the first position, it is connected to the positive electrode. At this time, the distance between the filter electrode 220 and the air inlet electrode 210 is small, which is conducive to forming a high-intensity electric field, so that the ion module 200 can function as a plasma device. When the filter electrode 220 moves to the second position, it is connected to the neutral wire or ground wire, so that the ion module 200 can function as a negative ion device. In this way, by adjusting the connection relationship between the filter electrode 220 and the power supply device 270, the type of ions generated by the ion module 200 can be controlled. The ion module 200 can function as a negative ion device to adsorb pollutant particles and improve the condensation and frosting effect of the temperature control device 110, and it can also function as a plasma device to deodorize and sterilize, and prevent corrosion of the organic coating on the surface of the temperature control device 110, thus meeting different application scenarios.

[0115] Optionally, such as Figure 12 As shown, the ion module 200 also includes a first terminal 271 and a second terminal 272. The first terminal 271 is connected to the positive terminal of the power supply device 270 and corresponds to the first moving position. The second terminal 272 is connected to the neutral or ground wire of the power supply device 270 and corresponds to the second moving position. The filter electrode 220 is connected to the first terminal 271 in the first moving position and to the second terminal 272 in the second moving position. Thus, when the filter electrode 220 moves to the first position, it is connected to the positive terminal through the first terminal 271; when the filter electrode 220 moves to the second position, it is connected to the neutral or ground wire through the first terminal 271.

[0116] Optionally, such as Figure 12As shown, the moving device 300 includes a telescopic member 301 and a driving member 302. The first end of the telescopic member 301 is connected to the filter screen pole portion 220. The driving member 302 is connected to the second end of the telescopic member 301 and is used to drive the telescopic member 301 to extend or retract along the moving direction of the first filter screen portion 221. Thus, when the driving member 302 drives the telescopic member 301 to extend, it moves the filter screen pole portion 220 towards a second moving position; when the driving member 302 drives the telescopic member 301 to retract, it moves the filter screen pole portion 220 towards a first moving position.

[0117] Optionally, the drive unit 302 includes an electrically driven structure, such as an electrically operated telescopic rod. Optionally, the drive unit 302 includes a pneumatically driven structure, such as a pneumatically operated telescopic rod.

[0118] Optionally, the ion module 200 also includes a mounting frame 241. The mounting frame 241 is used to mount the filter electrode 220, and the drive unit 302 is disposed on the mounting frame 241. In this way, the mounting frame 241 provides mounting space for the drive unit 302.

[0119] Optionally, the distance between the filter electrode 220 at the first moving position and the temperature regulating device 110 is d4, and the distance between the first moving position and the second moving position is d5, where 0.4 ≤ d5 / d4 ≤ 1. Optionally, 0.6 ≤ d5 / d4 ≤ 1. For example, the value of d5 / d4 can be selected from 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, or 1.

[0120] Optionally, 4mm ≤ d5 ≤ 10mm. For example, the value of d5 can be 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm.

[0121] Optionally, the housing 100 also includes an air outlet 102, and the ion module 200 further includes an air outlet electrode 280. The air outlet electrode 280 is located at the air outlet 102 and is connected to the negative terminal of the power supply device 270. Under the action of the air outlet electrode 280, air can be ionized to generate negative ions, thereby neutralizing the positive ions in the flowing airflow, so that the ratio of positive and negative ions in the air blown out from the air outlet 102 reaches a relatively balanced level, meeting the user's health needs.

[0122] In some embodiments, the air handling unit includes a housing 100 and an ionization module 200. The housing 100 has an air inlet 101 and a temperature regulating device 110 inside. The ionization module 200 includes a filter electrode portion 220 disposed between the air inlet 101 and the temperature regulating device 110. The filter electrode portion 220 includes a movable first filter portion 221 and a movable second filter portion 222. The filter electrode portion 220 has a third movable position and a fourth movable position. Figure 13As shown, the third moving position corresponds to the first filter portion 221 and the second filter portion 222 being located on the same plane. Figure 14 As shown, the fourth moving position corresponds to the first filter part 221 and the second filter part 222 being located on two spaced-apart planes, wherein the first filter part 221 is close to the temperature regulating device 110 and connected to the negative terminal of the power supply device 270, and the second filter part 222 is close to the air inlet 101 and connected to the positive terminal of the power supply device 270.

[0123] In this embodiment, when the filter pole 220 is in the third position, the first filter portion 221 and the second filter portion 222 are located on the same plane, which facilitates a large-area coverage of the temperature regulating device 110. This allows the filter pole 220 to evenly diffuse the flowing airflow onto the surface of the temperature regulating device 110. When the filter pole 220 is in the fourth position, a high-intensity electric field is formed between the first filter portion 221 and the second filter portion 222. This high-intensity electric field ionizes the gas, generating charged particles. These charged particles move directionally under the influence of the electric field force, colliding with neutral air molecules and transferring kinetic energy, ultimately forming a macroscopic airflow, i.e., ion wind, which blows towards the temperature regulating device 110. Thus, when the temperature regulating device 110 defrosts, the filter pole 220 is moved to the fourth position. At this time, the ion wind can directly blow defrost water, which facilitates the rapid falling of water droplets and reduces the amount of water droplets remaining on the surface of the temperature regulating device 110.

[0124] Optionally, such as Figure 14 As shown, the ion module 200 also includes a third terminal 273 and a fourth terminal 274. The third terminal 273 is connected to the negative terminal of the power supply 270. The fourth terminal 274 is connected to the positive terminal of the power supply 270. In the fourth movable position, the first filter portion 221 is connected to the third terminal 273, and the second filter portion 222 is connected to the fourth terminal 274. Thus, the first filter portion 221 can be connected to the negative terminal via the third terminal 273, and the second filter portion 222 can be connected to the positive terminal via the fourth terminal 274.

[0125] Optionally, the ion module 200 further includes a first moving component 310 and a second moving component 320. The first moving component 310 drives the first filter portion 221 to move along a first direction. The second moving component 320 drives the second filter portion 222 to move along a second direction perpendicular to the first direction. Thus, the first filter portion 221 and the second filter portion 222 can move independently.

[0126] Optionally, the first direction is the front-to-back direction, with the temperature regulating device 110 located in front of the filter screen pole portion 220. The second direction is the up-down direction, with the first filter screen portion 221 corresponding to the lower part of the temperature regulating device 110, and the second filter screen portion 222 located above the first filter screen portion 221.

[0127] Optionally, the first moving component 310 includes a first push rod 311 and a first driving device 312. A first end of the first push rod 311 is connected to the first filter portion 221. The first driving device 312 is connected to the second end of the first push rod 311 and is used to drive the first push rod 311 to extend or retract in a first direction. Thus, when the first driving device 312 drives the first push rod 311 to extend, the first filter portion 221 moves closer to the temperature regulating device 110, that is, moves forward. When the first driving device 312 drives the first push rod 311 to retract, the first filter portion 221 moves backward.

[0128] Optionally, the second moving component 320 includes a slider 321, a track 322, and a second driving device. The slider 321 is connected to the second filter portion 222. The track 322 is arranged along a second direction, and the slider 321 is slidably disposed on the track 322. The second driving device is used to drive the slider 321 to move along the track 322. Thus, when the second driving device drives the slider 321 to slide downward along the track 322, the second filter portion 222 moves downward. When the second driving device drives the slider 321 to slide upward along the track 322, the second filter portion 222 moves upward.

[0129] Optionally, when the filter screen pole 220 switches from the third moving position to the fourth moving position, the first driving device 312 is first controlled to drive the first filter screen part 221 forward through the first push rod 311, and then the second driving device is controlled to drive the second filter screen part 222 downward through the sliding member 321.

[0130] Optionally, the ion module 200 further includes a third moving component 330, which includes a second push rod 331 and a third driving device 332. The first end of the second push rod 331 is connected to the second filter section 222. The third driving device 332 is fixedly mounted on the sliding member 321 and connected to the second end of the second push rod 331, for driving the second push rod 331 to extend or retract in a first direction. Thus, when the third driving device 332 drives the second push rod 331 to extend, the second filter section 222 moves closer to the temperature regulating device 110, i.e., moves forward. When the third driving device 332 drives the second push rod 331 to retract, the second filter section 222 moves backward. Furthermore, under the simultaneous movement of the first moving component 310 and the third moving component 330, the first filter part 221 and the second filter part 222 can move synchronously. In this way, the two can still be located on the same plane after moving synchronously. This is the same as the function of the moving device 300 described above. That is, the filter pole part 220 can also be moved between the first moving position and the second moving position by using the first moving component 310 and the third moving component 330.

[0131] Optionally, the ion module 200 also includes a mounting frame 241, on which the first moving component 310, the second moving component 320 and the third moving component 330 are all disposed.

[0132] Optionally, the ion module 200 further includes a rotating assembly 340, which includes a fourth driving device 341 and two rotating shafts 342. The two rotating shafts 342 are respectively disposed at both ends of the mounting frame 241, and the fourth driving device 341 is connected to either rotating shaft 342 and can drive it to rotate. Thus, the fourth driving device can drive the mounting frame 241 to rotate as a whole, thereby adjusting the direction of the ion airflow, and this rotation does not affect the movement of the filter electrode 220 driven by the first moving assembly 310, the second moving assembly 320, and the third moving assembly 330. For example, the ion airflow can be directed diagonally downwards to facilitate the removal of defrost water.

[0133] In combination with the above embodiments, under the action of the first moving component 310, the second moving component 320, the third moving component 330 and the rotating component 340, the ion module 200 can form a variety of motion states, and thus is applicable to a variety of scenarios.

[0134] In some embodiments, the air handling equipment includes an air conditioner, the temperature regulating device 110 includes a heat exchanger 120, and the air conditioner includes a self-cleaning mode. The self-cleaning mode sequentially includes a pre-sterilization stage, a condensation stage, a frosting stage, a defrosting stage, and a corrosion prevention stage.

[0135] During the pre-sterilization stage, the air inlet section 210 is connected to the negative electrode, and the filter section 220 moves to the first moving position to connect to the positive electrode. At this time, the ion module 200 functions as a plasma device. In this way, pre-sterilization is performed using the ion module 200, reducing bacteria adsorbed by hydrated negative ions during the condensation stage. During this stage, the air conditioner's fan 130 operates, and the air outlet section 280 is connected to the negative electrode to balance the ratio of positive to negative ions in the blown-out air.

[0136] During the condensation stage, the air inlet electrode 210 is connected to the negative electrode, and the filter electrode 220 moves to the second position to connect to the neutral or ground wire. At this time, the ion module 200 acts as a negative ion device. Water molecules in the air combine with negative ions to form hydrated negative ions. After adsorbing pollutant particles in the air, the hydrated negative ions adhere evenly to the surface of the heat exchanger 120 and condense into water droplets.

[0137] During the frosting stage, heat exchanger 120 cools down and fan 130 stops, and water droplets on the surface of heat exchanger 120 begin to frost.

[0138] During the defrosting stage, the heat exchanger 120 heats up while the fan 130 stops, and the frost on the surface of the heat exchanger 120 begins to melt. The filter screen electrode 220 moves to the fourth position, at which point the first filter screen part 221 is connected to the negative electrode and the second filter screen part 222 is connected to the positive electrode, thereby forming an ion wind that directly blows the defrosting water, which facilitates the rapid falling of water droplets and reduces the water droplets remaining on the surface of the temperature regulating device 110. Furthermore, the airflow direction of the ion wind can be adjusted using the rotating component 340.

[0139] During the corrosion prevention stage, the air inlet electrode 210 is connected to the negative electrode, and the filter electrode 220 is moved to the first moving position to connect to the positive electrode. In this way, the ions retained on the surface of the heat exchanger 120 in the above stage move towards the air inlet electrode 210 under the action of potential difference, thereby avoiding corrosion of the organic coating on the surface of the heat exchanger 120 by the retained ions.

[0140] In some embodiments, the air handling equipment includes an air conditioner, the temperature regulating device 110 includes a heat exchanger 120, and the air conditioner includes an adaptive switching mode. In the adaptive switching mode, the air conditioner can adjust the type of ions generated by the ion module 200 according to preset parameters.

[0141] Optionally, the type of ions generated by the ion module 200 can be adjusted according to the indoor temperature and humidity.

[0142] When the indoor humidity is greater than or equal to a first humidity level and the indoor temperature is greater than or equal to a first temperature level, the ion module 200 operates as a plasma module 200. Plasma is relatively stable under high humidity, but bacteria and odors increase significantly when combined with high temperature. At this time, the hydroxyl radicals of the plasma can destroy bacterial cell membranes and decompose organic odor molecules. Optionally, the first humidity level is 60% RH, and the first temperature is 26℃.

[0143] When the indoor humidity is greater than or equal to a first humidity level and the indoor temperature is less than a first temperature level, the ion module 200 first operates as a plasma device for a first duration, and then as a negative ion device for a second duration, with the first duration being longer than the second duration. Under high humidity and low temperature conditions, bacterial activity decreases, and the damp, low temperature can make users feel cold and damp. In this situation, the plasma device acts as the primary ion generator, while the negative ion generator acts as a secondary ion generator, simultaneously sterilizing and deodorizing while improving the user's comfort.

[0144] When the indoor humidity is lower than the first humidity level and the indoor temperature is greater than or equal to the first temperature level, the ion module 200 first operates as a negative ion device for a third time, and then as a plasma device for a fourth time, with the third time being longer than the fourth time. In this case, the negative ion device is the primary function, and the plasma device is secondary. Under low humidity conditions, negative ions can quickly settle dust and PM2.5 particles, primarily addressing dust accumulation caused by insufficient window opening in high-temperature environments. Secondly, high temperatures increase the activity of a small number of bacteria in low-humidity environments, which can be effectively sterilized by short-term operation of the plasma device.

[0145] When the indoor humidity and temperature are both below a certain threshold, the ion module 200 operates as a negative ion module 200. In a dry environment with low temperature and low humidity, the negative ion device can efficiently adsorb pollutant particles, and the released negative charge can neutralize the positive charge in the air, reducing static electricity issues for users. Furthermore, bacterial activity is low in a dry environment with low temperature and low humidity, eliminating the need to switch to the plasma device.
