[0049] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0050] Combination Figures 1 to 12 As shown, this disclosure provides an air purification device to implement the air purification method provided in this disclosure. The air purification device includes an air purification component 10 and a blow-out section. The air purification component 10 includes an atomizing section 100 and an ionization section 200. The atomizing section 100 is configured with an atomizing chamber and an outlet. The atomizing section 100 is used to atomize water into droplets, and the atomized droplets are discharged through the outlet. The ionization section 200 includes a hydrophobic electrode 212 and a hydrophilic electrode 211. The hydrophobic electrode 212 and the hydrophilic electrode 211 are used to form an electrostatic field acting on the outlet. The hydrophilic electrode 211 is used to adsorb the atomized droplets and ionize the droplets. The hydrophobic electrode 212 is used to ionize the atomized droplets and the air.

[0051] In this embodiment, "negative ion water mist" and "water and negative ions" both refer to negatively charged droplets. "Water and hydroxyl ions" refers to droplets combined with hydroxyl radicals, which are also a type of "water and negative ions." When negative ions exist as free ions, they exist in the air for a relatively short time. However, when negative ions combine with droplets, they can exist in the air for a longer period of time, thus achieving air purification over a longer duration and a wider area.

[0052] The ionization unit 200 is positioned corresponding to the mist outlet and forms an electrostatic field acting on the mist outlet. The ionization unit 200 includes multiple electrodes 210, which are distributed in a ring around the circumference of the mist outlet. This ensures that most, or even all, of the droplets discharged through the mist outlet pass through the electric field. When the multiple electrodes are energized, an electrostatic field is formed. Because these multiple electric fields can be superimposed, a higher electric field strength is achieved near the mist outlet. Compared to increasing the voltage of a single electrode, using multiple electrodes increases the coverage area of ​​the electric field and improves the safety of the air purification component 10.

[0053] After the droplet enters the electric field, a series of changes occur in the electric field, generating a large amount of water and negative ions through droplet splitting, high-voltage ionization, and contact with negative ions.

[0054] Before entering an electrostatic field, a droplet has an initial velocity and is roughly spherical due to the combined effects of liquid surface tension and air resistance. Upon entering the electric field, the charge on the droplet surface becomes non-uniformly distributed and accumulates at locations with greater droplet curvature, further altering the droplet's shape. This change in shape exacerbates the non-uniformity of charge distribution. At these charge-rich locations, the repulsive force between charges overcomes the liquid surface tension, causing the droplet to split into smaller droplets. During this splitting process, the smaller droplets tend to become negatively charged, forming smaller-diameter water molecules and negative ions. In the electric field created by the electrodes, water molecules in the droplet are ionized, generating hydroxyl groups. Droplets carrying more hydroxyl groups become water molecules and negative ions. Additionally, some gases in the air are ionized in the electric field, also generating negative oxygen ions. These negative oxygen ions then react with droplets to form water molecules and negative ions. Of these three methods, due to the larger number of droplets in the electric field, ionizing water molecules is easier than ionizing gaseous components in the air. Therefore, the combination of droplets with hydroxyl groups generated from ionized water molecules to form water molecules and negative ions is more common.

[0055] Hydroxyl radicals possess strong oxidizing properties and high reactivity. They can supply lipids, proteins, and carbohydrates to microbial cell membranes, thereby disrupting cell membrane integrity, causing leakage of contents, and ultimately killing microorganisms. Hydroxyl radicals can also react with nucleic acid molecules, interfering with the transmission and replication of microbial genetic information. Furthermore, hydroxyl radicals can cause oxidative modification of microbial proteins, thus destroying their protein activity. When hydroxyl radicals interact with microbial biomolecules, they may also generate reactive oxygen species such as hydrogen peroxide and superoxide anions, further killing the microorganisms. Because hydroxyl radicals can react rapidly with almost all types of organic molecules, they are effective against a wide variety of microorganisms.

[0056] Hydroxyl radicals combine with droplets to form water and negative ions. As droplets with a relatively large surface area, water and negative ions can collide and merge with dust and microorganisms in the air, thus capturing them. Because water and negative ions are negatively charged, while dust and impurities in the air are positively charged, the water and negative ions can further capture these impurities under the influence of Coulomb force. After water and negative ions aggregate with dust and impurities, they form larger particle clusters. Their movement characteristics in the air change, the influence of gravity becomes more significant, and dust and impurities are more likely to separate from the airflow and settle.

[0057] Furthermore, some droplets entering the electrostatic field are atomized a second time under the influence of electrostatic force. Due to the reduced droplet diameter, the droplets are more easily suspended in the air and diffuse more fully. In addition, smaller diameter droplets have a larger specific surface area, which is beneficial for the droplets to combine with hydroxyl radical ions and with purifying targets such as dust, bacteria, and microorganisms. Smaller diameter droplets are more easily ionized to generate hydroxyl groups, which also increases the number of water and negative ions carrying hydroxyl groups.

[0058] After being ejected from the mist outlet, the droplets move forward and diffuse. When the electrodes have water-absorbing properties, some droplets can be adsorbed by the hydrophilic electrode 211. After being adsorbed by the hydrophilic electrode 211, the droplets come into direct contact with it. These droplets more easily gain electrons from the electrode, thus undergoing secondary atomization and becoming water and negative ions after gaining electrons. This configuration improves the secondary atomization and ionization effect of water.

[0059] Electrodes without water absorption properties have less direct contact with water, ionizing both water molecules and gas molecules in the air. The ionization of gas molecules generates a large number of negative ions, which are beneficial for the formation of water and negative ions to capture dust, impurities, and large molecules in the air. Furthermore, the hydrophilic electrode 211 more easily ionizes water molecules adsorbed on it, generating a large number of hydroxyl radicals. This facilitates the formation of water, hydroxyl groups, and hydroxyl radicals, thereby eliminating pathogens in the air. This configuration allows the air purification component 10 to not only eliminate pathogens but also effectively capture odor molecules and dust impurities in the air, improving its overall air purification capability.

[0060] The air purification component 10 provided in this embodiment uses a hydrophobic electrode 212 to generate an electric field, causing droplets to undergo electrostriction and break into smaller droplets. The hydrophilic electrode 211 can directly contact water, ionizing the water to generate ions, primarily hydroxyl groups. These hydroxyl groups combine with the droplets to form relatively stable water and hydroxyl groups, allowing the components to remain in the air for a longer period.

[0061] In the embodiments disclosed herein, unless otherwise specified, "electrode" refers to at least one of the hydrophobic electrode 212 and the hydrophilic electrode 211.

[0062] Optionally, the voltage of the electrode is greater than or equal to 4 kV and less than or equal to 10 kV.

[0063] Excessive voltage at the electrodes results in a stronger electric field, making air molecules more easily ionized and generating more free radicals and ions. These high-energy particles promote the reaction between nitrogen and oxygen, producing more nitrogen oxides. Conversely, insufficient voltage may fail to effectively ionize water molecules and break droplets into charged droplets, resulting in insufficient charged droplets to purify the air.

[0064] Nitrogen molecules require approximately 9.8 eV of energy to dissociate, oxygen molecules require approximately 5.1 eV, and water molecules require 4.80 eV. The energy gained by electrons accelerated in an electric field is related to their mean free path; within the 4kV-10kV voltage range, the electron energy distribution is mainly concentrated in the 1-5 eV range. Within this range, neither nitrogen nor oxygen molecules can be directly ionized. However, droplets can be split into smaller droplets, and water molecules can also be ionized. Although nitrogen and oxygen molecules can continue to be ionized through multi-stage collisions, the number of ionized molecules is significantly reduced, thus suppressing the formation of nitrogen oxides and ozone.

[0065] Optionally, the distance between the electrode and the mist outlet is greater than or equal to 5 mm and less than or equal to 50 mm.

[0066] Based on the relationship between electric field strength and distance, a moderately strong electric field can be formed between the mist outlet and the electrode when the distance is within the range of 5mm-50mm. If the distance is less than 5mm, the electric field strength is too high, which can easily lead to instability in the electric field and even abnormal phenomena such as corona discharge, affecting the normal operation of the system. On the other hand, if the distance is greater than 50mm, the electric field strength may be too weak to effectively act on the droplets, such as preventing the droplets from splitting and charging as expected.

[0067] Within this distance range, the electric field distribution is relatively uniform. A uniform electric field is beneficial for applying a more consistent force to the droplets exiting the mist outlet, making the droplet behavior in the electric field more predictable and consistent. For example, processes such as droplet splitting and charging are more stable and uniform, which helps improve the stability and controllability of the misting effect. After the droplets are ejected from the mist outlet, within a distance of 5mm-50mm, the droplets have sufficient time to split and ionize under the influence of the electric field. This distance can prevent excessive accumulation or splashing of droplets under the influence of the electric field.

[0068] In addition, such a distance not only reduces the risk of electrical faults such as short circuits and breakdowns between the electrode and the mist outlet, but also facilitates the installation, commissioning and maintenance of the equipment.

[0069] Optionally, the electric field strength of the electric field formed by the electrode at the mist outlet is greater than or equal to 80 kV / m and less than or equal to 2000 kV / m.

[0070] When the electric field strength reaches 80 kV / m or higher, the electric field force can exert sufficient force on the molecules on the liquid surface. For common liquids, such as aqueous solutions containing surfactants, this electric field strength can enable the molecules on the liquid surface to overcome surface tension and begin to form tiny droplets, thus achieving a preliminary atomization effect. If the electric field strength is lower than this value, it cannot provide enough energy to overcome the surface tension of the liquid, resulting in poor atomization, difficulty in droplet formation, or excessively large droplets. When the electric field strength is too high, exceeding 2000 kV / m, excessive ionization may occur in the gas environment around the electrode, causing the gas to break down and forming plasma channels. This not only consumes a large amount of electrical energy but may also damage the equipment, such as electrode ablation. Moreover, excessive ionization may cause the droplets to be subjected to unstable electric field forces during the formation process, resulting in uneven droplet size and distribution, affecting the quality and effect of atomization.

[0071] At the mist outlet, the liquid is subjected to the combined effects of an electric field and surface tension. The electric field attempts to deform the liquid surface and draw the liquid into filaments or droplets, while surface tension attempts to maintain the integrity of the liquid. Within an electric field strength range of 80 kV / m to 2000 kV / m, a reasonable balance between the electric field and surface tension can be achieved, allowing the liquid to break into droplets in a suitable manner.

[0072] Under the influence of an electric field, liquids undergo polarization, resulting in a charge distribution on the droplet surface. Within this electric field strength range, the charge distribution on the droplet surface enables the droplet to rapidly interact with ions or other droplets in the surrounding environment after leaving the mist outlet, further promoting droplet refinement and uniform distribution. Furthermore, within this electric field strength range, the gas maintains good insulation properties while simultaneously participating in the atomization and diffusion process. The gas's insulation properties ensure a stable electric field distribution, allowing the electric field to act effectively on the droplets without causing disordered electric field distribution due to excessive ionization or breakdown of the gas, thus ensuring the stability and controllability of the atomization process.

[0073] Optionally, a pulsed electric field is generated when the electrodes are energized.

[0074] A pulsed electric field can increase energy density significantly in a short time, which is beneficial for the ionization of water molecules. Furthermore, the number of hydroxyl radicals generated by the air purification component 10 can be adjusted by controlling the interval of the pulsed electric field.

[0075] Optionally, a DC electric field is generated when the electrodes are energized.

[0076] The form of a DC electric field has a relatively stable electric field strength, which can reduce or avoid the phenomenon of arc discharge on the electrodes, thus reducing the operating noise of the air purification component 10 and improving its safety.

[0077] Optionally, the diameter of the droplets discharged by the atomizing section 100 is less than or equal to 10 micrometers.

[0078] Such small-diameter droplets are conducive to ionization, generating hydroxyl radicals, as well as water and negative ions.

[0079] Optionally, the ionization section 200 also includes an electrode support 220, which is provided corresponding to the mist outlet. The electrode support 220 has multiple electrode fixing positions, and the multiple electrodes are disposed at the multiple electrode fixing positions.

[0080] The ionization unit 200 provides mounting positions for multiple electrodes via the electrode support 220. When the multiple electrodes are mounted on the electrode support 220, they can maintain a preset distance from the mist outlet. The multiple electrodes 210 are arranged in a ring. Since the mist outlet is located within the inner ring of the electrodes, droplets discharged through the mist outlet travel a shorter distance before entering the electric field, improving the secondary atomization and ionization effect of the ionization unit 200 on the droplets. Furthermore, the superposition of multiple electrodes to form an electric field provides a hardware basis for the air purification component 10 to regulate the distribution range and intensity of the electric field by controlling the opening and closing of individual electrodes and adjusting the voltage of individual electrodes.

[0081] Optionally, the electrode holder 220 is configured with multiple mounting slots, and multiple electrodes are fixed in the mounting slots.

[0082] This setup allows for the use of electrodes made of different materials and facilitates individual control of the voltage and switching on / off states of multiple electrodes.

[0083] Optionally, the ionization section 200 includes a plurality of electrode supports 220, which are spaced apart.

[0084] This configuration can increase the electric field strength and expand the effective range of the electric field, thereby improving the secondary atomization and ionization effect of water and increasing the amount of water, negative ions, and hydroxyl radicals generated.

[0085] Optionally, the electrode holder 220 is provided with multiple turns of electrode fixing positions, and each turn of electrode fixing positions includes multiple electrode fixing positions.

[0086] This configuration can increase the electric field strength and expand the effective range of the electric field.

[0087] Optionally, the ionization section 200 further includes an electrode ring 223 surrounding the atomizing section 100, the electrode ring 223 having a plurality of protrusions to form a plurality of electrodes.

[0088] The electrode support 220 includes an electrode ring 223, which is made of a conductive material. Due to the tip discharge effect, charge accumulates at the protruding parts of the electrode ring 223, which essentially act as electrodes, forming an electric field. This arrangement reduces the cost of the ionization section 200 and allows the voltages between multiple electrodes to be synchronized.

[0089] Optionally, at least a portion of the electrodes of the plurality of electrodes extend in the mist-emission direction of the atomizing section 100.

[0090] This configuration reduces the resistance to movement of the water mist discharged from the atomizing section 100, thereby increasing the overall mist output of the air purification component 10.

[0091] Optionally, the ionization section 200 includes a plurality of electrode rings 223, which are spaced apart.

[0092] This configuration can further increase the electric field strength and expand the effective range of the electric field, thereby improving the secondary atomization and ionization effect of water and increasing the amount of water, negative ions, and hydroxyl radicals generated.

[0093] Optionally, the electrode ring 223 is provided with multiple turns of electrodes, which are arranged concentrically at intervals, and each turn of electrodes is provided with multiple electrodes.

[0094] This configuration can increase the electric field strength and expand the effective range of the electric field.

[0095] Optionally, the ionization section 200 includes a plurality of hydrophobic electrodes 212 and a plurality of hydrophilic electrodes 211, which are distributed circumferentially along the mist outlet.

[0096] Optionally, the electrode support 220 is provided corresponding to the mist outlet, and a plurality of hydrophobic electrodes 212 and a plurality of hydrophilic electrodes 211 are disposed on the electrode support 220; wherein, the electrode support 220 includes an outer ring 222, which is coaxially disposed with the mist outlet of the atomizing part 100; the hydrophilic electrodes 211 extend radially from the outer ring 222 along the mist outlet, and / or, the hydrophobic electrodes 212 extend axially from the outer ring 222 along the mist outlet.

[0097] The hydrophilic electrode 211 extends radially from the outer ring 222 along the mist outlet, and can form an electric field component in the radial direction of the mist outlet. This allows the droplets discharged from the mist outlet to also be subjected to electric field force in the radial direction, which helps guide the droplets to move towards the hydrophilic electrode 211. This better realizes the function of the hydrophilic electrode 211 to adsorb and ionize the atomized droplets, and at the same time, it can make the droplets more evenly distributed in the radial direction, improving the uniformity of the electric field effect on the droplets.

[0098] The hydrophobic electrode 212 extends axially from the outer ring 222 along the mist outlet, generating a strong electric field along the axial direction of the mist outlet. This electric field, combined with the radial electric field, forms a more complex and effective three-dimensional electric field distribution. This electric field distribution can act more comprehensively on the droplets exiting the mist outlet, ensuring that the droplets are subjected to electric fields in both the axial and radial directions after leaving the mist outlet. This further promotes the ionization and splitting processes of the droplets, improving the generation efficiency of water and negative ions.

[0099] Optionally, the atomizing section 100 includes an atomizing tube 110, which has an atomizing chamber, and an atomizing outlet is provided at one end of the atomizing tube 110; wherein, the electrode support 220 is sleeved on the atomizing tube 110, and multiple electrodes are distributed along the circumference of the atomizing tube 110.

[0100] The atomizing chamber of the atomizing tube 110 is used to accommodate the atomized object and the atomizing assembly. The atomizing assembly atomizes the object into droplets and discharges the droplets from the mist outlet. For example, the atomized object is water, and the atomizing assembly includes an ultrasonic atomizing plate 113. By using the atomizing tube 110, the atomizing section 100 has a smaller volume and facilitates the installation of the electrode support 220 and the electrode ring 223. Multiple electrodes are distributed circumferentially along the atomizing tube 110, and the electrostatic field formed by the multiple electrodes covers the mist outlet of the atomizing tube 110.

[0101] Optionally, the atomizing section 100 includes an ultrasonic atomizing plate 113, which is disposed in the atomizing chamber and atomizes water into droplets during operation.

[0102] Optionally, the atomizing unit 100 also includes a mist outlet nozzle 114, which is disposed at the mist outlet and has multiple mist outlet holes.

[0103] When the diameter of the atomized droplets is close to or larger than the diameter of the mist outlet, the droplets will be intercepted by the mist outlet nozzle 114. Setting the mist outlet nozzle 114 helps to control the diameter of the droplets discharged from the atomizing section 100, thereby reducing or preventing large droplets from settling and accumulating near the usage location to form water accumulation.

[0104] Optionally, the atomizing unit 100 also includes a charging component 115, which is electrically connected to the atomizing chamber to precharge the water before atomization.

[0105] Pre-charging the water during atomization allows it to carry a certain negative charge upon atomization. When such droplets enter the electric field, they are more easily atomized and ionized by Coulomb forces, generating more hydroxyl radicals. It should be noted that because multiple electrodes are arranged circumferentially along the atomization outlet, even if charged droplets experience Coulomb forces in the electric field, they will not leave the effective range of the electric field due to repulsion before being fully utilized. For example, the charging component 115 includes a conductive material, and a voltage is applied to the conductive material to pre-charge the water in the atomization chamber.

[0106] Optionally, the charging component 115 includes a photocatalyst and an ultraviolet light source, with the photocatalyst disposed in the atomization chamber and the ultraviolet light source irradiating towards the photocatalyst.

[0107] For example, the photocatalyst includes TiO2. When the photocatalyst is irradiated with ultraviolet light, it generates electron-hole pairs. These holes can react with water molecules to generate hydroxyl radicals. Specifically, photoholes react with oxidized water molecules to form hydroxyl radicals. The hydroxyl radicals are negatively charged, pre-charging the water in the atomization chamber. Furthermore, irradiation with the ultraviolet light source can also disinfect the water in the atomization chamber.

[0108] Optionally, multiple electrodes can be moved along the length of the atomizing tube 110 to adjust the position of the mist outlet in the electrostatic field.

[0109] Optionally, the atomizing unit 100 further includes a guide member 120, which is disposed at the mist outlet and is used to guide the droplets discharged through the mist outlet to the locations of multiple electrodes.

[0110] The guide element 120 precisely guides the droplets discharged from the mist outlet, directing them towards the locations of multiple electrodes. This prevents droplets from failing to fully enter the electric field region due to random diffusion, ensuring that the droplets accurately enter the electrostatic field formed by the hydrophobic electrode 212 and the hydrophilic electrode 211. This increases the contact probability between the droplets and the electric field, creating favorable conditions for subsequent ionization and splitting processes, thereby effectively improving the generation efficiency of water and negative ions. By precisely guiding the droplets to the electrode locations, the electric field can be fully utilized to treat the droplets. This allows more droplets to undergo the expected physical changes under the influence of the electric field, improving the overall droplet utilization efficiency of the air purification component 10.

[0111] Optionally, the atomizing tube 110 includes a tube body 111 and an end cap 112, wherein the tube body 111 is configured with an atomizing chamber; the end cap 112 is connected to one end of the tube body 111 and has an atomizing outlet; wherein the electrode support 220 and the end cap 112 are integrally formed; or, the electrode support 220 and the tube body 111 are integrally formed; or, the electrode support 220, the tube body 111 and the end cap 112 are integrally formed.

[0112] Because the electrode holder 220 and end cap 112 are integrated, the number of independent components is reduced, thus simplifying the installation and maintenance process. The fixed relative position between the mist outlet and the electrode holder 220 improves the accuracy of the electric field acting on the droplets. Furthermore, this integrated design reduces connection points, enhancing the overall structural stability and durability. Directly integrating the electrode holder 220 into the tube body 111 makes the entire device more compact, reduces external connectors, and increases overall strength. In addition, reducing assembly steps lowers production costs and improves efficiency. The integrated structure of the electrode holder 220, tube body 111, and end cap 112 provides a compact and robust overall structure, reducing the number of independent components. This helps the air purification assembly 10 maintain consistent performance over long-term use.

[0113] Optionally, the electrode support 220 includes a plurality of spokes 221 and an outer ring 222, wherein the plurality of spokes 221 are distributed circumferentially along the tube body 111, and one end of the spokes 221 is connected to the end cap 112 or the tube body 111; the outer ring 222 is sleeved on the tube body 111 and connected to the other end of the spokes 221.

[0114] The spokes 221 and the outer ring 222 work together to form a stable frame structure, enhancing the mechanical strength of the entire assembly, especially under external forces or vibrations. The multiple spokes 221 effectively disperse the pressure from the outer ring 222, preventing localized stress concentration and reducing the risk of breakage. The perforated window between the multiple spokes 221 and the outer ring 222 allows the air purification assembly 10 to have an airflow path along the axial direction of the atomizing tube 110. With the aid of an external aerodynamic source such as a fan, the axial flow of air along the atomizing tube 110 allows the atomized droplets to flow in a specific direction and mix with the air during the flow. This mixing with the air facilitates the further diffusion of water, negative ions, and hydroxyl radicals.

[0115] Optionally, the air purification component 10 also includes a water supply unit 300, which is connected to the atomizing unit 100 and is used to supply water to the atomizing unit 100.

[0116] The water supply unit 300 can provide a stable water supply to the atomizing unit 100, so that the air purification component 10 can continuously humidify, deodorize and remove dust from the air.

[0117] Optionally, the water supply unit 300 includes a water supply pipe 310, and the water supply hose is connected to the atomizing chamber.

[0118] Supplying water to the atomizing section 100 via the water supply pipe 310 allows the water storage container to be placed away from the atomizing section 100, thereby reducing structural and electromagnetic interference to the atomizing section 100 and the ionization section 200.

[0119] Optionally, the water supply unit 300 also includes a water-absorbing material 320, which is disposed in the water supply pipe 310 and extends to the atomizing chamber.

[0120] The absorbent material 320 has a porous structure, enabling water pumping through capillary action. With this configuration, the water supply unit 300 can supply water to the atomizing unit 100 without the need for a pump or other power components, reducing the size and cost of the air purification assembly 10. Furthermore, the absorbent material 320's inherent properties allow for control of the water supply rate, thereby minimizing or preventing water overflow from the atomizing unit 100.

[0121] Optionally, the water supply unit 300 also includes a water box 330, which is connected to the atomizing chamber via a water supply pipe 310.

[0122] This configuration not only improves the continuous operation capability of the air purification component 10, but also reduces the cost and size of the air purification component 10.

[0123] Optionally, the height of the water box 330 is higher than the height of the atomizing chamber.

[0124] In this way, the water in the water box 330 can enter the atomization chamber under the action of gravity, and the water supply unit 300 does not need a water pump or other power components, which is conducive to the miniaturization of the air purification component 10.

[0125] It should be noted that, in this case, the aforementioned water-absorbing material 320 can be installed simultaneously. The water supply pipe 310, equipped with water-absorbing material 320, allows for control of the water supply speed.

[0126] Optionally, the air purification device further includes a fan 420 and a screen 430. The duct assembly 410 is constructed with a purification duct and has an air inlet and an air outlet that connect to the purification duct. The fan 420 is used to drive air to flow from the air inlet to the air outlet. The air purification component 10 is slidably disposed on the duct assembly 410. The screen 430 is disposed opposite to the air purification component 10 in the purification duct, and the relative distance between the air purification component 10 and the screen 430 is adjusted when the air purification component 10 slides.

[0127] The air purification device provided in this embodiment includes two air purification methods. The first method is to purify the air flowing through the air duct assembly 410, whereby indoor air is circulated through the air duct assembly 410 and thus purified. The second method is to deliver water and negative ions to the indoor environment 224 to purify the indoor environment 224.

[0128] When the fan 420 is running, the air pushes the charged droplets toward the interception net 430. The greater the initial velocity of the charged droplets, the easier it is for them to break through the interception net 430 and be discharged from the air outlet; the smaller the initial velocity of the charged droplets, the easier it is for them to be intercepted by the interception net 430. The greater the distance between the interception net 430 and the air purification component 10, the easier it is for the charged droplets to diffuse and be intercepted by the interception net 430; the smaller the distance between the interception net 430 and the air purification component 10, the easier it is for the charged droplets to concentrate and break through the interception net 430 and be discharged from the air outlet.

[0129] The air purification device provided in this embodiment allows for adjustment of the distance between the air purification component 10 and the interceptor net 430 by sliding the air purification component 10, thereby balancing the air purification and humidification functions of the air purification device. For example, when the humidity of the environment where the air purification device is located is high, sliding the air purification component 10 increases the distance between the air purification component 10 and the interceptor net 430, allowing fewer droplets to enter the environment where the air purification device is located; conversely, when the humidity of the environment where the air purification device is located is low, sliding the air purification component 10 decreases the distance between the air purification component 10 and the interceptor net 430, allowing more droplets to enter the environment where the air purification device is located, thereby increasing the humidity of the environment.

[0130] Optionally, the direction of mist output of the air purification component 10 is the same as the direction of airflow in the purification duct.

[0131] When the air purifier is running, the lower the air resistance of the purification duct, the greater the airflow through the duct, and the better the air purification effect of the air purifier on the surrounding environment. The mist outlet direction of the air purification component 10 is the same as the airflow direction of the purification duct, which can reduce the kinetic energy loss of the droplets, thereby increasing the airflow of the air purifier. In addition, the mist outlet direction of the air purification component 10 is the same as the airflow direction, both facing the interception net 430. This is conducive to the full contact between charged droplets and air, capturing dust, impurities and microorganisms in the air over a large area, and blowing them evenly towards the interception net 430.

[0132] Optionally, the air purification component 10 includes a sliding part 11, an atomizing part 12, and a connecting part 13, wherein the sliding part 11 is located outside the purification duct; the atomizing part 12 is connected to the sliding part 11 and located inside the purification duct; and the connecting part 13 passes through the slide groove and is used to connect the sliding part 11 and the atomizing part 12.

[0133] The sliding part 11 of the air purification component 10 is located outside the purification duct, while the atomizing part 12 is located inside the purification duct. The connecting part 13 of the air purification component 10 passes through the slide groove to connect the sliding part 11 and the atomizing part 12. With this arrangement, the various functional parts of the air purification component 10 have clear division of labor, which is beneficial to the sliding and atomizing of the air purification component 10.

[0134] Optionally, the sliding part 11 includes a water supply section 300, which has a water storage space.

[0135] The sliding part 11 is equipped with a water supply section 300, the water outlet of which is higher than that of the atomizing part 12. This allows water in the water supply section 300 to naturally replenish the atomizing part 12 under gravity. With this configuration, the air purification component 10 can supply water to the atomizing part 12 without a water pump or other power source, simplifying its structure and reducing its cost. Furthermore, when the water storage space of the sliding part 11 contains water, its greater weight helps the air purification component 10 to remain stably positioned in the purification duct within a preset location.

[0136] Optionally, the air purification device further includes a fan 420 and a screen 430. The duct assembly 410 is constructed with a purification duct and has an air inlet and an air outlet that connect to the purification duct. The fan 420 is used to drive air to flow from the air inlet to the air outlet. The air purification component 10 is disposed in the duct assembly 410. The screen 430 is opposite to the air purification component 10 and is slidably disposed in the purification duct. The relative distance between the screen 430 component and the screen 430 is adjusted when the screen 430 component slides.

[0137] Using the air purification device provided in this embodiment, the charged droplets formed by the air purification component 10 can capture dust, impurities and pathogens in the air, and have a certain disinfection effect on pathogens, thus improving air quality; the droplets generated during the operation of the air purification device can also humidify the environment where the air purification device is located; since the interception net 430 is in the form of a sliding arrangement, the distance between the air purification component 10 and the interception net 430 can be adjusted by moving the air purification component 10, thereby adjusting the humidification rate of the air purification component 10.

[0138] It should be noted that when the interceptor net 430 is in a sliding position, the air purification component 10 can also be slidably positioned. This allows for more flexible adjustment of the relative distance between the air purification component 10 and the interceptor net 430.

[0139] Optionally, the flow equalization plate 440 is disposed between the fan 420 and the air purification component 10.

[0140] When the fan 420 operates, it generates turbulent airflow. The flow equalization plate 440, located between the fan 420 and the air purification assembly 10, uses multiple flow equalization holes to rectify this turbulent airflow. The flow equalization plate 440 makes the airflow within the purification duct more uniform and stable. This stable airflow is crucial for the air purification process because it allows droplets to flow along a predetermined path through the air purification assembly 10. Furthermore, the flow equalization plate 440 also serves a protective function. Because it is located between the fan 420 and the air purification assembly 10, when foreign objects enter the purification duct through the fan 420, the flow equalization plate 440 can block these objects, preventing them from directly impacting the air purification assembly 10.

[0141] Optionally, the fan 420 is disposed within the purification duct of the duct assembly 410.

[0142] Integrating the fan 420 within the purification duct makes the entire air purification device more compact. This layout reduces the extra space required for the connection between the fan 420 and the duct assembly 410, facilitating miniaturization and allowing the device to adapt to various installation scenarios, such as easier placement in confined indoor environments. The fan 420, directly within the purification duct, drives airflow more efficiently. Since air does not need to pass through complex transfer structures to enter the fan 420, energy loss during transmission is reduced. The fan 420 can directly power the air within the purification duct, ensuring a stable flow rate and volume from the inlet to the outlet, thus improving air purification efficiency. Furthermore, the integrated design of the fan 420 and the duct assembly 410 facilitates comprehensive troubleshooting of any abnormal airflow issues within the air purification device.

[0143] Optionally, the flow equalization plate 440 is disposed at the docking position between the fan 420 and the air duct assembly 410.

[0144] Because the airflow at the outlet of the fan 420 is turbulent, the flow equalization plate 440 is positioned at the docking point to immediately regulate the turbulent airflow from the fan 420. As soon as the airflow enters the duct assembly 410, the flow equalization holes on the flow equalization plate 440 begin to function, quickly homogenizing the chaotic airflow and ensuring a relatively stable and orderly flow from the initial stage of entering the purification duct. This provides a good airflow foundation for the subsequent air purification process within the duct. This position allows the flow equalization plate 440 to maximize the use of the initial kinetic energy of the airflow from the fan 420, effectively equalizing the airflow before it generates more complex turbulence and secondary flow within the duct assembly 410. This helps to further improve the flow equalization effect, ensuring a more uniform airflow distribution throughout the purification duct, making the movement of droplets within the purification duct more stable, and improving the purification efficiency of the air purification assembly 10. Furthermore, removing the fan 420 allows the flow equalization plate 440 to be fully exposed, facilitating user installation and removal of the flow equalization plate 440.

[0145] Optionally, the axis of the flow equalization orifice is oriented toward the air purification component 10.

[0146] With the flow equalization orifice axis oriented towards the air purification component 10, the airflow, after being rectified by the flow equalization plate 440, flows more precisely to the air purification component 10. This is like planning a clear path for the airflow, allowing it to impact the air purification component 10 in a more orderly manner. This ensures that droplets move in a specific direction within the purification duct, improving the contact efficiency between air and droplets, making the purification process more thorough and efficient. The orderly flow of airflow towards the air purification component 10 along the axis of the flow equalization orifice reduces irregular disturbances to the droplets. Because of the stable airflow, droplets are more likely to maintain their trajectory, moving along the predetermined path within the purification duct, reducing collisions and disorderly dispersion between droplets. This helps maintain the stability of the droplets during the purification process, further improving the air purification effect and efficiency.

[0147] Optionally, the fan 420 includes a centrifugal fan 420, and the flow equalization plate 440 is disposed at the air outlet of the centrifugal fan 420.

[0148] The centrifugal fan 420 has a large air volume and a certain angle between the air outlet direction and the air inlet direction. This helps to introduce a large amount of air into the air purification device, thereby improving the purification efficiency of the air purification device.

[0149] Optionally, the electrode holder 220 is annular and its axis faces the air outlet of the purification duct.

[0150] The air purification device provided in this embodiment has an annular electrode support 220 with its axis aligned with the airflow direction. This reduces air resistance and increases the airflow of the air purification device. Furthermore, the annular electrode support 220 facilitates electrode placement at different locations, ensuring optimal working positions for the electrodes within the purification duct. The annular design also allows for the placement of multiple electrodes, increasing the distribution range of negative ions within the purification duct and thus enhancing the air purification effect of the device.

[0151] Optionally, the electrode extends radially along the electrode support 220.

[0152] The electrodes extend radially along the electrode support 220, increasing the distance between two adjacent electrodes, increasing the effective range of the electrodes, and improving the air purification capacity of the air purification device.

[0153] Optionally, the electrode holder 220 includes an inner ring 224, an outer ring 222, and a plurality of spokes 221, wherein the outer ring 222 is used to fix the electrode; the inner ring 224 is adapted to be fixed in a preset installation position; and the plurality of spokes 221 extend along a plurality of radial lines of the inner ring 224, with one end of the spokes 221 connected to the inner ring 224 and the other end connected to the outer ring 222.

[0154] The inner ring 224 of the electrode holder 220 provides a fixed position for the electrode holder 220. The outer ring 222 is connected to the inner ring 224 by a plurality of spokes 221. The opening between the inner ring 224 and the outer ring 222 serves as an air channel allowing air to pass through. The outer ring 222 provides a mounting position for the electrode.

[0155] In order to meet different air purification needs, combined with Figure 13 As shown, this disclosure provides a method for controlling an air purification device, comprising:

[0156] S01, the air purification device determines the current air purification needs.

[0157] S02, the air purification device selectively activates one or more of the atomizing section, hydrophilic electrode, and hydrophobic electrode according to the control and purification requirements.

[0158] In this embodiment of the disclosure, the air purification device has multiple operating modes, including at least two or more of the following: sterilization mode, dust removal mode, odor removal mode, and humidification mode.

[0159] Air purification devices include an atomizing unit, a hydrophilic electrode, and a hydrophobic electrode.

[0160] When only the atomizing section is running, water is atomized into small droplets. These small droplets then enter the environment where the air purifier is located, thereby increasing the ambient humidity.

[0161] When the atomizing unit stops operating and the hydrophilic and / or hydrophobic electrodes are in operation, an electric field is generated. This electric field ionizes gas molecules in the air, forming negative ions. Dust and other particulate matter in the air are positively charged and attract these negative ions, causing them to aggregate and settle. This is how the air purification device removes dust.

[0162] When the atomizing unit and the hydrophilic electrode operate together, the hydrophilic electrode adsorbs small droplets and ionizes them into hydroxyl ions. These hydroxyl ions can inactivate bacteria, viruses, and other microorganisms in the air, thus sterilizing the air purifier. If the hydrophobic electrode operates simultaneously, it can ionize the air to generate ozone, which provides some auxiliary sterilization.

[0163] When the atomizing unit and hydrophilic electrode operate together, the hydrophilic electrode generates hydroxyl ions, which can decompose organic odor molecules. This helps the air purifier remove odors. If the hydrophobic electrode operates simultaneously, it ionizes the air to produce ozone, which can decompose inorganic odor molecules in the air. This further assists the atomizing unit and hydrophilic electrode in their odor-removing function.

[0164] The method provided in this disclosure allows for flexible switching of humidification, dust removal, odor removal, and sterilization functions according to environmental needs by selecting one or more of the atomizing unit, hydrophilic electrode, and hydrophobic electrode. This design enables the air purification device to more efficiently address different air quality issues and improve the user experience.

[0165] Combination Figure 14 As shown, this disclosure provides another method for controlling an air purification device, wherein a hydrophilic electrode is configured to generate hydroxyl ions for sterilization, and a hydrophobic electrode is configured to generate ozone for sterilization; the method includes:

[0166] S01, the air purification device determines the current air purification needs.

[0167] S211, when the primary air purification requirement is sterilization, the air purifier activates the atomizing unit and the hydrophilic electrode, and deactivates the hydrophobic electrode.

[0168] S212, the air purification device activates the atomizing section, hydrophilic electrode, and hydrophobic electrode when the current air purification requirement is the second sterilization requirement.

[0169] Under the first sterilization requirement, sterilization is mainly achieved through hydroxyl free ions, water, and hydroxyl ions. Under the second sterilization requirement, sterilization is achieved through hydroxyl free ions, water, hydroxyl ions, and ozone. For example, the first sterilization requirement is a highly efficient sterilization mode targeting bacteria and viruses, while the second sterilization requirement is a comprehensive sterilization mode targeting bacteria, viruses, and odors.

[0170] Hydroxyl ions are strong oxidants that can destroy the cell membranes, proteins, and DNA of microorganisms, rendering them inactive. Hydroxyl ions have a rapid sterilization effect and do not produce harmful residues. Ozone is also a strong oxidant that can penetrate the cell walls of microorganisms, destroying their internal structure. Ozone has a strong bactericidal effect, but excessively high concentrations may irritate the human respiratory tract, therefore its use needs to be controlled.

[0171] Users or the system determine whether a primary or secondary sterilization requirement is needed based on the current environment's sterilization needs. The primary sterilization requirement is suitable for scenarios requiring a strong sterilization effect but not requiring ozone (such as ordinary households and offices). The secondary sterilization requirement is suitable for scenarios requiring a stronger sterilization effect and tolerating a small amount of ozone (such as hospitals and laboratories).

[0172] Under the primary sterilization requirement, the atomizing unit atomizes water into small droplets. Hydrophilic electrodes adsorb these droplets and ionize them to generate hydroxyl ions. The generated hydroxyl ions exist in two forms. The first is free hydroxyl ions, which exist in the air as free ions and possess strong oxidizing properties. They can directly destroy the cell structure of bacteria, viruses, and other microorganisms, rendering them inactive. The second form is water and hydroxyl ions, which combine with the droplets to form water and hydroxyl ions. This form is also effective for sterilization. Hydroxyl ions have a strong sterilization effect and do not produce ozone, making them suitable for ozone-sensitive environments.

[0173] Under the second sterilization requirement, the atomizing section and hydrophilic electrode generate hydroxyl ions during operation, exerting a sterilization effect (as described in step S211). Simultaneously, the hydrophobic electrode ionizes the air to generate ozone, which also has strong oxidizing properties and can further kill bacteria and viruses. The synergistic effect of hydroxyl ions and ozone achieves a better sterilization effect.

[0174] In this embodiment, the hydrophilic electrode, when operating together with the atomizing unit, can generate hydroxyl ions. Some of these hydroxyl ions can exist in the air as free ions, while others combine with droplets to form water and hydroxyl ions. Both free hydroxyl ions and water / hydroxyl ions can have a bactericidal effect.

[0175] The control method provided in this disclosure can achieve efficient air purification by flexibly configuring the operating states of the atomizing part, hydrophilic electrode and hydrophobic electrode according to different sterilization needs. This design enables the air purification device to better adapt to diverse usage needs, while taking into account both sterilization effect and safety.

[0176] Optionally, the ozone concentration is controlled between 0.05 ppm and 0.1 ppm.

[0177] Low ozone concentrations result in poor sterilization. High ozone concentrations can easily harm human health. Maintaining ozone concentrations between 0.05 ppm and 0.1 ppm allows for more effective air disinfection within a safe range.

[0178] Combination Figure 15 As shown, this disclosure provides another method for controlling an air purification device, wherein a hydrophilic electrode is configured to generate hydroxyl ions to oxidize and decompose organic odor molecules, and a hydrophobic electrode is configured to generate ozone to decompose inorganic odor molecules; one or more of the atomizing section, hydrophilic electrode, and hydrophobic electrode are selectively activated according to the purification control requirements, the method comprising:

[0179] S01, the air purification device determines the current air purification needs.

[0180] S221, the air purifier activates the atomizing section and hydrophilic electrode when the primary air purification requirement is odor removal.

[0181] S222, when the current air purification demand is the second demand for odor removal, the air purifier activates the atomizing part and the hydrophilic electrode, and also activates the hydrophobic electrode.

[0182] S223, the air purifier activates the hydrophobic electrode when the current air purification requirement is the third requirement of odor removal.

[0183] In this embodiment of the disclosure, different components are selectively activated to decompose odors according to different odor removal requirements (first odor removal requirement, second odor removal requirement, and third odor removal requirement):

[0184] Hydrophilic electrode: Generates hydroxyl ions for the oxidative decomposition of organic odor molecules. Hydrophobic electrode: Generates ozone for the decomposition of inorganic odor molecules. Atomizing section: Atomizes water into small droplets, assisting the hydrophilic electrode in generating hydroxyl ions.

[0185] The first odor removal requirement primarily targets organic odors (such as those from food, tobacco, and pets). The second odor removal requirement addresses the combined treatment of organic and inorganic odors (such as in complex odor environments like kitchens and bathrooms). The third odor removal requirement primarily targets inorganic odors (such as chemical smells and ammonia).

[0186] To address the primary need for odor removal, the atomizing unit atomizes water into small droplets. These droplets are then adsorbed by a hydrophilic electrode and ionized to generate hydroxyl ions. These hydroxyl ions possess strong oxidizing properties, effectively decomposing organic odor molecules in the air (such as aldehydes, ketones, and volatile organic compounds).

[0187] To address the secondary odor removal need, the atomizing unit and hydrophilic electrode generate hydroxyl ions during operation, which decompose organic odor molecules. The hydrophobic electrode ionizes the air to generate ozone, which can decompose inorganic odor molecules (such as ammonia and hydrogen sulfide). The synergistic effect of hydroxyl ions and ozone can simultaneously treat both organic and inorganic odors.

[0188] For the third odor-neutralizing need, the hydrophobic electrode ionizes the air to generate ozone, which can efficiently decompose inorganic odor molecules. Because the atomizing unit and hydrophilic electrode are not activated, the generation of hydroxyl ions is suppressed, focusing solely on the odor-neutralizing effect of ozone. Suitable for laboratories, chemical plants, sewage treatment plants, and other places where inorganic odors are present. Highly effective against inorganic odors. Simple to operate and low energy consumption.

[0189] The control method provided in this disclosure, by flexibly configuring the operating states of the atomizing unit, hydrophilic electrode, and hydrophobic electrode, can achieve efficient odor decomposition according to different odor removal needs. This design allows the air purification device to better adapt to diverse odor treatment requirements, while balancing effectiveness and safety.

[0190] Combination Figure 16 As shown, this disclosure provides another method for controlling an air purification device, wherein a hydrophobic electrode is configured to generate air ions to charge particulate matter and cause it to aggregate into particulate matter, and a hydrophilic electrode is configured to generate water and negative ions; the method includes:

[0191] S01, the air purification device determines the current air purification needs.

[0192] S231, the air purification device activates the hydrophobic electrode when the primary air purification requirement is dust removal.

[0193] S232, the air purification device activates the atomizing section and hydrophobic electrode when the current air purification requirement is the second dust removal requirement.

[0194] S233, the air purification device activates the atomizing section, hydrophobic electrode, and hydrophilic electrode when the current air purification requirement is the third dust removal requirement.

[0195] When the hydrophobic electrode is in operation, it ionizes the air to generate a large number of negative ions. These negative ions combine with the air, causing dust and other particulate matter to gather and settle.

[0196] This method selectively activates different components to achieve particulate matter charging, aggregation, and sedimentation based on different dust removal requirements (primary, secondary, and tertiary dust removal). A hydrophobic electrode generates negative air ions, charging the particles and causing them to aggregate into larger particles, facilitating sedimentation or filtration. The atomizing section atomizes water into small droplets, aiding in particle aggregation and sedimentation. A hydrophilic electrode generates hydroxyl ions, further enhancing the particle charging and aggregation effects.

[0197] The first dust removal requirement is suitable for environments with low particulate matter concentrations, requiring only the activation of the hydrophobic electrode. The second dust removal requirement is suitable for environments with high particulate matter concentrations, requiring the activation of both the atomizing unit and the hydrophobic electrode. The third dust removal requirement is suitable for environments with extremely high particulate matter concentrations requiring highly efficient purification, requiring the activation of both the atomizing unit and the hydrophobic and hydrophilic electrodes.

[0198] For primary dust removal needs, the hydrophobic electrode ionizes the air to generate negative ions. These negative ions combine with airborne particulate matter (such as dust and pollen), causing the particles to become charged. The charged particles attract each other and aggregate into larger particles. Due to their increased weight, they eventually settle to the ground or are captured by the filter. Suitable for environments with low particulate matter concentrations, such as homes and offices. Simple to operate and low energy consumption. Suitable for daily air purification.

[0199] For the second dust removal requirement, the atomizing unit atomizes water into small droplets. These droplets combine with airborne particles, increasing their weight. A hydrophobic electrode generates negative ions, charging the particles and causing them to aggregate further. The synergistic effect of the droplets and negative ions makes the particles easier to settle or filter. This results in a stronger dust removal effect, capable of handling higher concentrations of particulate matter. The addition of droplets enhances the aggregation and settling of particles.

[0200] For the third dust removal requirement, the atomizing section generates droplets, increasing the weight of the particles. The hydrophobic electrode generates negative ions, causing the particles to become charged and aggregate. The hydrophilic electrode generates hydroxyl ions, further enhancing the charging effect of the particles and decomposing some organic particles. This method offers the strongest dust removal effect and can handle extremely high concentrations of particulate matter. The addition of hydroxyl ions further improves the purification efficiency.

[0201] The control method provided in this disclosure, by flexibly configuring the operating states of the atomizing unit, hydrophobic electrode, and hydrophilic electrode, can achieve efficient air purification according to different dust removal needs. The first dust removal need is suitable for low-concentration particulate matter, requiring only the activation of the hydrophobic electrode. The second dust removal need is suitable for high-concentration particulate matter, requiring the activation of both the atomizing unit and the hydrophobic electrode. The third dust removal need is suitable for extremely high-concentration particulate matter, requiring the activation of the atomizing unit, the hydrophobic electrode, and the hydrophilic electrode. This design allows the air purification device to better adapt to diverse particulate matter purification needs, while balancing effectiveness and energy consumption. The synergistic effect of the three components causes particulate matter to rapidly aggregate, settle, or be filtered.

[0202] Combination Figure 17 As shown, this disclosure provides another method for controlling an air purification device, including:

[0203] S01, the air purification device determines the current air purification needs.

[0204] S241, the air purifier activates the atomizing section when the current air purification requirement is the primary humidification requirement.

[0205] S242, the air purification device activates the atomizing section and hydrophilic electrode when the current air purification demand is the second humidification demand.

[0206] For example, the first humidification requirement is a normal humidification requirement, and the atomizing unit is configured to generate atomized droplets to increase the ambient humidity; the second humidification requirement is a sterilization humidification requirement, and the hydrophilic electrode is configured to generate hydroxyl ions to sterilize while humidifying.

[0207] This method selectively activates different components to regulate ambient humidity based on different humidification needs (primary humidification need and secondary humidification need). The atomizing unit atomizes water into small droplets, directly increasing ambient humidity. Hydrophilic electrodes work in conjunction with the atomizing unit to adsorb droplets and generate hydroxyl ions, further enhancing humidification and air quality. The user or system determines the required humidification mode based on the current humidity requirements and air quality. Primary humidification need: only increases ambient humidity, suitable for environments with low humidity but good air quality. Secondary humidification need: increases humidity while improving air quality (e.g., sterilization, dust removal), suitable for environments with low humidity and poor air quality.

[0208] Under the initial humidification requirement, the atomizing unit atomizes water into small droplets, which are then released directly into the air to increase ambient humidity. The small droplet size allows for rapid evaporation and uniform distribution, thereby enhancing humidity.

[0209] For the second humidification requirement, the atomizing unit atomizes water into small droplets, directly increasing ambient humidity. The small droplet size allows for rapid evaporation and uniform distribution. A hydrophilic electrode adsorbs the droplets generated by the atomizing unit and ionizes them to generate hydroxyl ions. These hydroxyl ions have strong oxidizing properties, capable of killing bacteria and viruses, and decomposing odor molecules.

[0210] The control method provided in this disclosure can achieve efficient humidity regulation and air purification by flexibly configuring the operating states of the atomizing part and the hydrophilic electrode according to different humidification needs.

[0211] Optionally, when the air purifier is operating in odor-removing mode, the voltage of the hydrophilic electrode is greater than or equal to 5kV.

[0212] When an air purifier is operating in odor-removing mode, a voltage of 5kV or higher on the hydrophilic electrode is crucial. In odor-removing mode, activating the hydrophilic electrode and achieving a voltage of 5kV or higher allows it to more efficiently adsorb small droplets generated by the atomizing unit. Under this high voltage, the hydrophilic electrode's ionization ability for droplets is enhanced, generating more highly oxidizing hydroxyl ions. These abundant hydroxyl ions are highly effective in decomposing complex organic odor molecules in the air (such as those from food, tobacco, and pets), accelerating the oxidative decomposition process and improving odor removal efficiency.

[0213] When the odor-removing mode is activated using the hydrophobic electrode, a voltage of 5kV or higher enhances its ability to ionize air and produce ozone. The higher voltage strengthens the electric field around the hydrophobic electrode, more effectively ionizing oxygen molecules in the air into ozone molecules. Ozone is highly effective at decomposing inorganic odor molecules (such as chemical odors and ammonia). Sufficient ozone produced under high voltage can quickly react with inorganic odor molecules, destroying their molecular structure, thus playing a stronger role in treating inorganic odors. This is especially suitable for places with large amounts of inorganic odors, such as laboratories and chemical plants. Therefore, setting the voltage of the hydrophilic electrode (or hydrophobic electrode) to 5kV or higher when operating the odor-removing mode of an air purifier helps to better handle different types of odors and improves the overall odor-removing effect.

[0214] Optionally, when the air purifier is operating in humidification mode, the atomization power of the atomizing section is a first power; when the air purifier is operating in sterilization mode, the atomization power of the atomizing section is a second power; when the air purifier is operating in dust removal mode, the atomization power of the atomizing section is a third power; wherein, the first power is greater than the second power and the third power.

[0215] The atomization power setting of the atomizing unit varies in different operating modes of air purifiers, which is based on the functional characteristics and actual needs of each mode.

[0216] When the air purifier operates in humidification mode, the atomization power of the atomizing unit is set to the highest level, which is higher than the power in the other two modes. This is because the core objective of humidification mode is to increase ambient humidity, requiring the rapid atomization of a large amount of water into small droplets and their release into the air. A higher initial power allows the atomizing unit to operate more efficiently, producing more small droplets per unit time, thereby quickly and effectively increasing the moisture content in the environment. This meets the user's need for a rapid increase in indoor humidity, creating a suitable humidity environment for them.

[0217] In sterilization mode, the atomization power of the atomizing unit is the second power. In this mode, the main function of the atomizing unit is not simply to significantly increase humidity, but rather to provide the hydrophilic electrode with sufficient small droplets for ionization to generate hydroxyl ions. The hydrophilic electrode adsorbs these droplets generated by the atomizing unit and ionizes them. The generated hydroxyl ions are used to destroy the cell structure of bacteria, viruses, and other microorganisms, rendering them inactive. Therefore, the second power only needs to ensure a sufficient number of droplets for the hydrophilic electrode to carry out the ionization reaction; it does not need to generate a large number of droplets as in humidification mode, hence the power is lower than the first power.

[0218] When the air purifier operates in dust removal mode, the atomization power of the atomizing unit is the third power. In dust removal mode, the atomizing unit does not directly participate in the dust particle settling process. It mainly relies on the operation of hydrophilic and / or hydrophobic electrodes to create an electric field, ionizing gas molecules in the air to form negative ions. These ions attract positively charged dust particles, causing them to aggregate and settle. At this time, the atomizing unit is not a critical component; its operation is more about maintaining some auxiliary functions within the device, such as providing the necessary moisture environment for any other reactions that may occur. The atomization volume requirement is relatively low, so the third power is also low, lower than the first power in humidification mode.

[0219] By setting different atomization powers for different modes, the air purifier can efficiently regulate humidity in humidification mode and rationally allocate energy in sterilization and dust removal modes, ensuring that each mode meets functional requirements while achieving efficient energy utilization, thereby improving the overall performance and efficiency of the device.

[0220] Optionally, the second power is greater than the third power.

[0221] When the air purifier is in sterilization mode, the atomizing unit operates at its second power. As mentioned earlier, in sterilization mode, the key function of the atomizing unit is to supply sufficient small droplets to the hydrophilic electrode. After the hydrophilic electrode adsorbs these droplets, it ionizes them to generate hydroxyl ions, which are used to kill bacteria, viruses, and other microorganisms. This process requires a relatively stable and sufficient number of droplets to continuously generate hydroxyl ions to ensure effective microbial elimination. Therefore, the second power must be maintained at a certain level to ensure that the atomizing unit can generate enough droplets to meet the working requirements of the hydrophilic electrode and achieve efficient sterilization.

[0222] In dust removal mode, the atomizing unit operates at the third power level. Dust removal mode primarily relies on the electric field formed by hydrophilic and / or hydrophobic electrodes to ionize gas molecules in the air into negative ions. These ions then attract positively charged dust particles, causing them to aggregate and settle. In this process, the atomizing unit is not a core component; its role is relatively auxiliary. Its main function is to maintain a certain level of humidity within the device, providing the necessary conditions for ion generation and action. However, the required amount of water vapor is far less than the amount of droplets needed to generate hydroxyl ions in sterilization mode. Therefore, the third power level is set relatively low, lower than the second power level in sterilization mode. This satisfies the basic functional requirements of the atomizing unit in dust removal mode while effectively saving energy and avoiding unnecessary energy consumption.

[0223] The setting that the second power is greater than the third power precisely matches the different functional positioning and actual needs of the atomizing unit in the sterilization mode and the dust removal mode, which helps the air purification device to operate efficiently and energy-savingly in different modes.
