[0044] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0045] In order to purify indoor air while adjusting the humidification rate of the indoor environment, combined with Figure 1-12 As shown in the figure, this embodiment of the present disclosure provides an air purification device, which includes a duct assembly 410, a fan 420, an air purification component 10, and an intercepting net 430. The duct assembly 410 is constructed with a purification duct and has an air inlet and an air outlet that communicate with 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 and is used to atomize water into droplets and charge the droplets in the purification duct. The intercepting net 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 intercepting net 430 is adjusted when the air purification component 10 slides.

[0046] 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.

[0047] In this embodiment, the air purification device includes a duct assembly 410, and a fan 420 is disposed within the purification duct formed by the duct assembly 410 or directly or indirectly connected to the duct assembly 410. Exemplarily, the duct assembly 410 forms a tubular cavity, with its two ends serving as an air inlet and an air outlet, respectively. The fan 420 is disposed within the purification duct. When the fan 420 operates, it drives air to enter the duct from the air inlet and discharges the air from the air outlet after passing through the purification duct. The air is purified as it flows through the purification duct. Specifically, the air purification device also includes an air purification component 10 and an interceptor net 430. The air purification component 10 forms charged droplets, which are negatively charged. The interceptor net 430 is connected to the duct assembly 410 and is positively charged. After air enters the purification duct, dust, impurities, and pathogens in the air are captured by the charged droplets and attracted by the interceptor net 430 along with the charged droplets. The capture of dust, impurities, and pathogens in the air by charged droplets involves at least two mechanisms. The first mechanism involves the dust, impurities, and pathogens being positively charged as a whole, attracting the negatively charged droplets under the influence of Coulomb forces. The second mechanism involves the capture of dust, impurities, and pathogens upon contact with the droplets. Furthermore, during the formation of charged droplets and within the droplets themselves, some negatively charged ions, such as hydroxyl groups, with bactericidal properties are generated, which also play a role in eliminating pathogens.

[0048] 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.

[0049] 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.

[0050] 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 air purification component 10 is in a sliding configuration, 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.

[0051] Optionally, the direction of mist output of the air purification component 10 is the same as the direction of airflow in the purification duct.

[0052] 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.

[0053] Optionally, the air duct assembly 410 has a sliding groove that extends through the inside and outside, and the air purification assembly 10 is slidably disposed in the sliding groove. The air purification assembly 10 also includes a sliding baffle, which slides with the air purification assembly 10 and always covers the sliding groove.

[0054] The slide groove extends through the air duct assembly 410. When the air purification component 10 is slidably disposed in the slide groove, part of it is located inside the air duct assembly 410, and part of it is located outside the air duct assembly 410. This allows the air purification component 10 to slide by moving the outer portion, facilitating adjustment of the distance between the air purification component 10 and the interceptor mesh 430. The air purification component 10 slides between a first position and a second position on the slide groove. The length of the sliding baffle is greater than the length of the slide groove, ensuring that the slide groove is always covered during the sliding process of the air purification component 10. This keeps the purification air duct sealed, preventing air from entering the purification air duct from the slide groove or flowing out of the slide groove from the purification air duct.

[0055] 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.

[0056] 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.

[0057] Optionally, the sliding portion 11 and the atomizing portion 12 are located on the same side of the connecting portion 13; or, the sliding portion 11 is located on the side of the connecting portion 13 closer to the air inlet, and the atomizing portion 12 is located on the side of the connecting portion 13 closer to the air outlet.

[0058] In some cases, taking the vertical arrangement of the connecting portion 13 as an example, the sliding portion 11 and the atomizing portion 12 are located on the same side of the connecting portion 13, both extending from the connecting portion 13 towards the air outlet. With this arrangement, the center of the air purification component 10 is located at a position offset from the connecting portion 13 towards the air outlet, making it less likely for the air purification component 10 to tilt during sliding.

[0059] In some cases, taking the vertical arrangement of the connecting portion 13 as an example, the sliding portion 11 extends from the connecting portion 13 towards the air inlet, and the atomizing portion 12 extends from the connecting portion 13 towards the air outlet. With this arrangement, the sliding portion 11 is located far from the air outlet, which helps the air purifier to have a neater appearance at the outlet, thus facilitating its integration into household appliances.

[0060] Optionally, the sliding part 11 includes a water supply section 300, which has a water storage space.

[0061] 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.

[0062] Optionally, the water supply unit 300 includes a water storage box 330 and a lid, wherein the water storage box 330 is configured to store water and has an opening; the lid covers the opening of the water storage box 330.

[0063] The water supply unit 300 includes a water storage box 330 and a cover. Water can be added to the water supply unit 300 by opening the cover. This design makes it convenient for users.

[0064] Optionally, the atomizing part 12 includes an atomizing section 100 and an ionization section 200. The atomizing section 100 forms an atomizing chamber inside, which is connected to the water storage space. The atomizing chamber has a mist outlet, through which the atomized droplets are discharged. The ionization section 200 is provided corresponding to the mist outlet and forms an electric field acting on the mist outlet. The droplets discharged through the mist outlet flow through the electric field.

[0065] Before entering the electric field, the 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 begins to distribute non-uniformly, accumulating at locations with greater droplet curvature. During this process, the droplet's shape further changes. As the droplet's shape changes, the non-uniformity of charge distribution becomes more pronounced. At locations with concentrated charge, 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 droplets are ionized, generating hydroxyl groups. Droplets carrying more hydroxyl groups become water molecules and negative ions. In the electric field, some gases in the air are also ionized, generating negative oxygen ions. These negative oxygen ions, upon contact with the droplets, form water molecules and negative ions. Of the three methods mentioned above, since there are more droplets in the electric field, the energy required to ionize water molecules and split the droplets is less than the energy required to ionize nitrogen and oxygen in the air. Therefore, the droplets mainly combine with hydroxyl ions to form water and negative ions.

[0066] 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, water and negative ions can more easily capture dust and 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, and the influence of gravity becomes more significant, causing them to separate from the airflow and settle.

[0067] Furthermore, the process described above, where water and negative ions are formed through droplet splitting, is also a secondary atomization process. The splitting of larger droplets into smaller droplets can be considered secondary atomization. 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 also more easily ionized to generate hydroxyl groups, thus increasing the number of water and negative ions carrying hydroxyl groups.

[0068] Compared to dust removal methods that use negative ion generators, the air purification component 10 provided in this embodiment generates hydroxyl radicals from droplets, which can significantly reduce harmful gases such as nitrogen oxides and ozone generated by ionizing air. Compared to methods that only capture dust and pathogens through droplets, the air purification component 10 provided in this embodiment can kill microorganisms through the generated hydroxyl radicals, and the water and negative ions formed after the hydroxyl radicals combine with the droplets can more effectively combine with dust and impurities in the air. In addition, since the droplets are atomized a second time when passing through the electric field, the droplets have a larger specific surface area and can diffuse to a wider range in the air. The ionization section 200 provided at the mist outlet of the atomization section 100 can reduce the free movement distance of the droplets discharged from the mist outlet, thereby reducing the phenomenon of droplet agglomeration due to collision, improving atomization efficiency and ionization efficiency, and improving the sterilization and dust removal effects of the air purification component 10.

[0069] Optionally, the ionization section 200 includes an electrode support 220 and a plurality of electrodes 210, wherein the electrode support 220 is disposed corresponding to the mist outlet, the electrode support 220 has a plurality of electrode fixing positions, the plurality of electrode fixing positions are disposed along the circumference of the mist outlet; the plurality of electrodes are disposed at the plurality of electrode fixing positions.

[0070] The ionization unit 200 is positioned corresponding to the mist outlet and forms an electric field acting on the mist outlet. The ionization unit 200 includes multiple electrodes arranged in a ring around the circumference of the mist outlet, ensuring 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 electric field is formed; since 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. Furthermore, the arrangement of multiple electrodes around the circumference of the mist outlet ensures that all mist-like droplets discharged through the mist outlet can pass through the electric field.

[0071] Using the air purification component 10 provided in this embodiment, the droplets generated by the atomizing section 100 do not exhibit polarity and can move freely in the electric field, thereby generating more water and negative ions. Multiple electrodes are arranged circumferentially along the mist outlet, and the electric field effectively acts on most of the droplets discharged through the mist outlet, making the negative ionization of the droplets more complete and increasing the amount of water and negative ions generated. Multiple electrodes are arranged circumferentially along the mist outlet, allowing droplets and charged droplets to move towards the mist outlet in the mist discharge direction, which is beneficial for the air purification component 10 to control the diffusion direction of water and negative ions. Some droplets are ionized a second time in the electric field, which can improve the uniformity of the droplets and increase the specific area of ​​the droplets. The hydroxyl radicals generated by ionizing water can broadly disinfect microorganisms in the air. The droplets and hydroxyl radicals form water and negative ions, which can capture dust and impurities in the air. Through the above multiple mechanisms, air quality is improved in multiple ways.

[0072] Optionally, the voltage of the electrode is greater than or equal to 4 kV and less than or equal to 10 kV.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] When the electric field strength reaches 80 kV / m or higher, the electric field force can exert a 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.

[0080] 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.

[0081] Optionally, a pulsed electric field is generated when the electrodes are energized.

[0082] 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.

[0083] Optionally, a DC electric field is generated when the electrodes are energized.

[0084] 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 helping to reduce the operating noise of the air purification component 10 and improve its safety.

[0085] Optionally, the diameter of the droplets discharged by the atomizing section 100 is less than or equal to 10 micrometers.

[0086] Such small-diameter droplets are conducive to ionization, generating hydroxyl radicals, as well as water and negative ions.

[0087] 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.

[0088] 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.

[0089] Optionally, the electrode holder 220 is configured with multiple mounting slots, and multiple electrodes are fixed in the mounting slots.

[0090] 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.

[0091] Optionally, the ionization section 200 includes a plurality of electrode supports 220, which are spaced apart.

[0092] 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.

[0093] 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.

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

[0095] 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.

[0096] 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.

[0097] Optionally, at least a portion of the electrodes of the plurality of electrodes extend in the mist-emission direction of the atomizing section 100.

[0098] 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.

[0099] Optionally, the ionization section 200 includes a plurality of electrode rings 223, which are spaced apart.

[0100] 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.

[0101] 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.

[0102] This configuration can increase the electric field strength and expand the effective range of the electric field.

[0103] Optionally, the plurality of electrodes includes at least one hydrophilic electrode 211, which adsorbs droplets discharged from the mist outlet.

[0104] 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 due to Coulomb explosion, and gaining electrons to become water and negative ions. This configuration improves the secondary atomization and ionization effect of water.

[0105] Electrodes without water absorption properties have less direct contact with water, and while ionizing water molecules, they also ionize 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 and impurities in the air. Furthermore, the hydrophilic electrode 211 more easily ionizes water molecules adsorbed on it, generating a large number of hydroxyl radicals during ionization. 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 large odor molecules and dust impurities in the air, improving its overall air purification capability.

[0106] Optionally, the hydrophilic electrode 211 is made of graphite.

[0107] Graphite materials have a porous structure that allows them to adsorb droplets. Graphite materials also have good electrical conductivity, which allows them to provide electrons to the water in the hydrophilic electrode 211, promoting secondary atomization of the droplets.

[0108] Optionally, the hydrophilic electrode 211 includes multiple clustered conductive fiber bundles.

[0109] For example, the wire bundles are made of metal. The ends of individual wire bundles, due to the tip effect, act as areas of charge accumulation, thus forming an electric field. When multiple wire bundles are bundled together, they create pores, forming a structure that easily absorbs water.

[0110] Multiple clustered conductive fiber bundles can provide a larger specific surface area, significantly increasing the contact area between the hydrophilic electrode 211 and water or atomized micro-droplets. Numerous tiny gaps and channels exist between the conductive fiber bundles, creating a significant capillary effect. This capillary action allows water to rise and diffuse rapidly between the fiber bundles, accelerating water absorption and enabling the hydrophilic electrode 211 to quickly absorb surrounding moisture, thus performing its water absorption function effectively even in environments with low moisture content.

[0111] Multiple conductive fiber bundles effectively provide multiple parallel conductive channels. When an electric field is applied, current can be conducted through different bundles. Even if some bundles experience localized faults or poor contact, the overall conductivity remains unaffected, improving the stability and reliability of the conductivity and ensuring the continuous and stable ionization process. The clustered conductive fiber bundles form multiple conductive nodes at their contact points, which reduce the overall contact resistance. Based on the principle of parallel resistance, connecting multiple conductive fiber bundles in parallel reduces the total resistance, allowing a larger current to pass through at the same voltage. This improves ionization efficiency, enabling more water molecules to be ionized into water and negative ions.

[0112] Optionally, when the hydrophilic electrode 211 comprises multiple aggregated conductive fiber bundles, the diameter of the conductive fiber bundles is greater than or equal to 5 micrometers and less than or equal to 80 micrometers.

[0113] A diameter of 5 micrometers or more ensures sufficient gaps between the conductive fiber bundles, generating effective capillary action, allowing the hydrophilic electrode 211 to rapidly absorb atomized droplets. Simultaneously, a diameter of less than 80 micrometers ensures that the capillary gaps are not excessively large, maintaining sufficient capillary force to allow water to rise and distribute stably between the fiber bundles, providing a sufficient water source for ionization. This moderate capillary action helps improve the water absorption efficiency of the hydrophilic electrode 211, thereby ensuring sufficient droplets are ionized and promoting the generation of water and negative ions. This diameter range ensures that the conductive fiber bundles have a suitable cross-sectional area to conduct current. On one hand, a sufficient cross-sectional area ensures good conductivity, allowing the electric field to effectively act on the adsorbed droplets, promoting droplet ionization. On the other hand, excessively thick fiber bundles prevent the electric field distribution from becoming overly concentrated on the surface, instead allowing the electric field to act uniformly on the droplets to a certain extent, improving ionization efficiency and contributing to the generation of more water and negative ions.

[0114] A suitable fiber bundle diameter can effectively capture atomized droplets and, to a certain extent, ensure that the droplets are evenly dispersed on the fiber bundle surface. This increases the contact area and time between the droplets and the electric field, improving the ionization effect. It also facilitates the diffusion of subsequently generated water and negative ions in the air, enhancing the air purification effect.

[0115] 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.

[0116] Multiple hydrophobic electrodes 212 and hydrophilic electrodes 211 are distributed circumferentially around the mist outlet, enabling a more uniform distribution of the electric field around the outlet. This ensures that droplets discharged from the outlet are subjected to a relatively uniform electric field force in all directions, avoiding situations where the electric field is too strong or too weak in some areas, thereby improving the stability and consistency of droplet ionization and air purification. When multiple electrodes are energized, their respective electric fields superimpose, significantly enhancing the electric field strength near the mist outlet. A stronger electric field can more effectively cause droplets to split and ionize, promoting the generation of more water and negative ions and improving the working efficiency of the air purification component 10. The multiple electrodes distributed circumferentially around the mist outlet can form a ring-shaped electric field region, covering most or even all of the droplets discharged from the outlet. Regardless of the angle or direction at which droplets are discharged from the outlet, they can enter the electric field region, ensuring that all droplets have the opportunity to be ionized and further processed, maximizing the function of the air purification component 10. A larger electric field coverage means a correspondingly larger air purification area. It can not only effectively purify the air near the mist outlet, but also expand to a larger surrounding space to a certain extent, so that the air purification component 10 can play a role in a wider area and improve the overall air purification effect.

[0117] Optionally, the atomizing section 100 includes an atomizing tube 110, which has an atomizing chamber and an outlet at one end; wherein, the electrode support 220 is sleeved on the atomizing tube 110 and multiple electrodes are distributed circumferentially along the atomizing tube 110.

[0118] 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 electric field formed by the multiple electrodes covers the mist outlet of the atomizing tube 110.

[0119] Optionally, the diameter of the atomizing tube 110 gradually increases along the airflow direction.

[0120] The end of the atomizing tube 110 near the air inlet serves to deliver water, while the end of the atomizing tube 110 near the air outlet needs to house the atomizing component. The gradually increasing diameter of the atomizing tube 110 ensures that there are no steps in the atomization along the airflow direction, reducing airflow resistance.

[0121] 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.

[0122] The ultrasonic atomizing plate 113 is small in size, has low power, and is also low in cost. Furthermore, the atomization power and atomization diameter of the ultrasonic atomizing plate 113 are easily adjustable. This configuration facilitates the matching of the atomizing section 100 and the ionization section 200, and also allows users to adjust the atomization diameter by adjusting the atomization power during use, thereby adjusting or switching the humidification, air purification, and sterilization functions of the air purification component 10.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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 oxidize 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.

[0129] Optionally, multiple electrodes can be moved along the length of the atomizing tube 110 to adjust the position of the mist outlet in the electric field.

[0130] As one implementation of multiple electrodes moving along the length of the atomizing tube 110, the electrode support 220 is slidably disposed on the atomizing tube 110; as another implementation of multiple electrodes moving along the length of the atomizing tube 110, the electrode ring 223 is slidably disposed on the atomizing tube 110. Taking the electrode support 220 slidably disposed on the atomizing tube 110 as an example, by adjusting the position of the electrode support 220, the position of the mist outlet in the electric field can be adjusted. Given a constant initial velocity of the droplet exiting from the mist outlet, the position of the mist outlet in the electric field affects the time required for the droplet to pass through the electric field. The time the droplet spends in the electric field, in turn, affects the secondary atomization and ionization effects of the droplet. Specifically, a longer residence time of the droplet in the electric field is beneficial for secondary atomization, while a higher electric field strength is beneficial for water ionization. Moving the electrode support 220 can be used as a means to adjust the electric field strength near the mist outlet, and can also adjust the time the droplet spends in the electric field, thereby adjusting the secondary atomization effect of the multiple electrodes on the droplet and the ionization effect on the water. Furthermore, the sliding arrangement of the electrode support 220 or electrode ring 223 makes the ionization section 200 easy to assemble, clean, and maintain.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] Optionally, the water supply unit 300 includes a water supply pipe 310, and the water supply hose is connected to the atomizing chamber.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] Optionally, the height of the water box 330 is higher than the height of the atomizing chamber.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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 electric 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.

[0148] The guide element 120 directs the droplets towards the electrode position, making the droplet distribution in the electric field more concentrated. This helps enhance the effect of the electric field on the droplets, because the electric field strength has a more significant impact on the droplets in a relatively concentrated area. Under this high-intensity and concentrated electric field environment, the droplets are more likely to undergo processes such as charge distribution changes, splitting into smaller droplets, and ionization, thereby generating water and negative ions more efficiently. Due to the effect of the guide element 120, the angle and position of the droplets entering the electric field are relatively stable, which is conducive to forming a more stable and effective interaction between the electric field and the droplets. This stable interaction mode makes the behavior of the droplets in the electric field more predictable, making it easier to further optimize the droplet treatment process by adjusting the electric field parameters, thereby improving the performance and stability of the air purification component 10.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] Optionally, the interception net 430 includes a mesh panel and a support portion, wherein the mesh panel has multiple mesh openings; the support portion extends from the mesh panel toward the air inlet or air outlet, and one side of the support portion abuts against the inner wall of the purification air duct.

[0153] The support portion of the interceptor mesh 430 serves as a frame arranged circumferentially along the mesh panel, which is supported by the support portion. Multiple mesh openings in the mesh panel are used to filter and screen a portion of the droplets. Specifically, the interceptor mesh 430 is in indirect contact with the air duct assembly 410 through the support portion and is positively charged. Dust and impurities in the air are also positively charged. Negatively charged droplets generated by the air purification assembly 10 easily come into contact with positively charged dust and impurities and are easily attracted and intercepted by the interceptor mesh 430. The interceptor mesh 430 can intercept a portion of the droplets while allowing another portion to pass through. The droplets passing through the interceptor mesh 430 have a smaller diameter and can diffuse a greater distance in the air, thus humidifying the indoor environment. At least one side of the support portion abuts against the inner wall of the purification air duct, thereby maintaining a preset angle within the purification air duct. For example, the purification air duct is arranged horizontally, and the interceptor mesh 430 is vertically arranged perpendicular to the purification air duct when at the preset angle.

[0154] With this configuration, the interceptor net 430 is easy to assemble and slide, and it has a good interception effect on droplets.

[0155] Optionally, the interceptor 430 includes multiple mesh panels.

[0156] With multiple mesh panels installed in the interceptor network 430, the difficulty for droplets to penetrate the interceptor network 430 increases, further improving the interception effect of the interceptor network 430.

[0157] Optionally, the bottom plate of the purification air duct is provided with a drainage groove, the interception net 430 abuts against the bottom plate, and the bottom of the interception net 430 and the drainage groove form a drainage channel.

[0158] After capturing dust and impurities, the droplets become dirty and have low utilization value. The droplets captured by the interceptor 430 will flow downwards along the interceptor 430 and flow outwards through the drainage channel. This arrangement allows for smoother drainage from the air purifier.

[0159] Optionally, the interceptor 430 is grounded.

[0160] With this configuration, the grounding effect of the interceptor 430 is better, enabling it to capture charged droplets more effectively.

[0161] 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.

[0162] 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 purify the indoor environment by delivering water and negative ions to the indoor environment.

[0163] In this embodiment, the air purification device includes a duct assembly 410, and a fan 420 is disposed within the purification duct formed by the duct assembly 410 or directly or indirectly connected to the duct assembly 410. Exemplarily, the duct assembly 410 forms a tubular cavity, with its two ends serving as an air inlet and an air outlet, respectively. The fan 420 is disposed within the purification duct. When the fan 420 operates, it drives air to enter the duct from the air inlet and discharges the air from the air outlet after passing through the purification duct. The air is purified as it flows through the purification duct. Specifically, the air purification device also includes an air purification component 10 and an interceptor net 430. The air purification component 10 forms charged droplets, which are negatively charged. The interceptor net 430 is connected to the duct assembly 410 and is positively charged. After air enters the purification duct, dust, impurities, and pathogens in the air are captured by the charged droplets and attracted by the interceptor net 430 along with the charged droplets. The capture of dust, impurities, and pathogens in the air by charged droplets involves at least two mechanisms. The first mechanism involves the dust, impurities, and pathogens being positively charged as a whole, attracting the negatively charged droplets under the influence of Coulomb forces. The second mechanism involves the capture of dust, impurities, and pathogens upon contact with the droplets. Furthermore, during the formation of charged droplets and within the droplets themselves, some negatively charged ions, such as hydroxyl groups, with bactericidal properties are generated, which also play a role in eliminating pathogens.

[0164] 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.

[0165] 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.

[0166] 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 air purification component 10 is in a sliding configuration, 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.

[0167] Optionally, the direction of mist output of the air purification component 10 is the same as the direction of airflow in the purification duct.

[0168] 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.

[0169] Optionally, the air duct assembly 410 has a sliding groove that extends through the inside and outside, and the air purification assembly 10 is slidably disposed in the sliding groove. The air purification assembly 10 also includes a sliding baffle, which slides with the air purification assembly 10 and always covers the sliding groove.

[0170] The slide groove extends through the air duct assembly 410. When the air purification component 10 is slidably disposed in the slide groove, part of it is located inside the air duct assembly 410, and part of it is located outside the air duct assembly 410. This allows the air purification component 10 to slide by moving the outer portion, facilitating adjustment of the distance between the air purification component 10 and the interceptor mesh 430. The air purification component 10 slides between a first position and a second position on the slide groove. The length of the sliding baffle is greater than the length of the slide groove, ensuring that the slide groove is always covered during the sliding process of the air purification component 10. This keeps the purification air duct sealed, preventing air from entering the purification air duct from the slide groove or flowing out of the slide groove from the purification air duct.

[0171] 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.

[0172] 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.

[0173] Optionally, the sliding part 11 and the atomizing part 12 are located on the same side of the connecting part 13; or, the sliding part 11 is located on the side of the connecting part 13 closer to the air inlet, and the atomizing part 12 is located on the side of the connecting part 13 closer to the air outlet.

[0174] In some cases, taking the vertical arrangement of the connecting portion 13 as an example, the sliding portion 11 and the atomizing portion 12 are located on the same side of the connecting portion 13, both extending from the connecting portion 13 towards the air outlet. With this arrangement, the center of the air purification component 10 is located at a position offset from the connecting portion 13 towards the air outlet, making it less likely for the air purification component 10 to tilt during sliding.

[0175] In some cases, taking the vertical arrangement of the connecting portion 13 as an example, the sliding portion 11 extends from the connecting portion 13 towards the air inlet, and the atomizing portion 12 extends from the connecting portion 13 towards the air outlet. With this arrangement, the sliding portion 11 is located far from the air outlet, which helps the air purifier to have a neater appearance at the outlet, thus facilitating its integration into household appliances.

[0176] Optionally, the sliding part 11 includes a water supply section 300, which has a water storage space.

[0177] 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.

[0178] Optionally, the water supply unit 300 includes a water storage box 330 and a lid, wherein the water storage box 330 is configured to store water and has an opening; the lid covers the opening of the water storage box 330.

[0179] The water supply unit 300 includes a water storage box 330 and a cover. Water can be added to the water supply unit 300 by opening the cover. This design makes it convenient for users.

[0180] Optionally, the air purification device also includes a flow equalization plate 440, which is disposed in the purification air duct and has multiple flow equalization holes. Air flows through the flow equalization plate 440 and the air purification component 10 in sequence under the drive of the fan 420.

[0181] When the fan 420 discharges air, there is considerable turbulence. This increases the instability of charged droplets in the purification duct. The air purification device provided in this embodiment also includes a flow equalization plate 440, which can rectify the airflow from the fan 420, thereby making the airflow in the purification duct more uniform and orderly, which is beneficial for droplets to flow through the air purification component 10 along a predetermined path and become charged. In addition, if foreign objects enter the fan 420, the flow equalization plate 440 also plays a protective role, preventing foreign objects from impacting the air purification component 10 and causing damage to the air purification component 10.

[0182] Optionally, the flow equalization plate 440 is disposed between the fan 420 and the air purification component 10.

[0183] 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.

[0184] Optionally, the fan 420 is disposed within the purification duct of the duct assembly 410.

[0185] 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 space-constrained indoor environments. The fan 420's direct location within the purification duct enables more efficient airflow. 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, thereby improving air purification efficiency. Furthermore, the integrated design of the fan 420 and duct assembly 410 facilitates comprehensive troubleshooting of any abnormal airflow issues within the air purification device.

[0186] Optionally, the air outlet of the fan 420 is connected to the air inlet of the duct assembly 410.

[0187] The design of the fan 420 and the duct assembly 410 being connected makes equipment maintenance more convenient. Maintenance personnel can more easily inspect, clean, or repair the fan 420 and the duct assembly 410 because their connection is relatively direct, allowing access to key components without complicated disassembly procedures, thus reducing maintenance costs and difficulty.

[0188] Optionally, the flow equalization plate 440 is disposed at the docking position between the fan 420 and the air duct assembly 410.

[0189] 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.

[0190] Optionally, the axis of the flow equalization orifice is oriented toward the air purification component 10.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] Optionally, the electrode holder 220 is annular and its axis faces the air outlet of the purification duct.

[0195] 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.

[0196] Optionally, the electrodes are oriented towards the air outlet.

[0197] After the electrodes are installed on the electrode holder 220, they extend from the electrode holder 220 towards the air outlet. This arrangement reduces the air resistance of the electrodes themselves, further increasing the airflow of the air purifier. In addition, the arrangement of the electrodes extending towards the air outlet can reduce or avoid electric arcing between the electrodes and the inner wall of the air duct assembly 410, improving the safety of the air purifier.

[0198] Optionally, the electrode extends radially along the electrode support 220.

[0199] 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.

[0200] 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.

[0201] 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.

[0202] Optionally, the hydrophilic electrode 211 extends radially from the outer ring 222 along the mist outlet.

[0203] This creates an electric field component in the radial direction of the mist outlet, allowing the droplets discharged from the mist outlet to be subjected to electric field forces in the radial direction as well. This helps guide the droplets toward the hydrophilic electrode 211, better enabling the hydrophilic electrode 211 to adsorb and ionize the atomized droplets. It also allows the droplets to be distributed more evenly in the radial direction, improving the uniformity of the electric field's effect on the droplets.

[0204] Optionally, the hydrophobic electrode 212 extends from the outer ring 222 along the axial direction of the mist outlet.

[0205] 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.

[0206] Optionally, the thickness of the outer ring 222 in the radial direction is less than its length in the axial direction.

[0207] The outer ring 222 has a hollow cylindrical structure. When air passes through the outer ring 222 of the electrode support 220, it is rectified by the outer ring 222, reducing turbulence and increasing laminar flow. This arrangement improves the stability of airflow through the outer ring 222, allowing air to flow through the electrode in an orderly manner.

[0208] Optionally, the diameter of the outer ring 222 gradually decreases along the direction of airflow.

[0209] The outer ring 222 of the electrode support 220 has a gradually narrowing shape. This creates a throttling effect on the airflow through the electrode support 220, making the adhesion effect more pronounced. This allows the airflow inside the outer ring 222 to be more stable and orderly. Furthermore, the airflow velocity inside the outer ring 222 is higher than that outside the outer ring 222. When the air inside the outer ring 222 reaches the end of the outer ring 222, it undergoes a diffusion and mixing process with the air outside the outer ring 222, which facilitates the collision, aggregation, and sedimentation of negatively charged particles with positively charged particles.

[0210] This disclosure provides an air conditioner, which includes a housing and the aforementioned air purification component 10. The housing has an air outlet, and the air purification component 10 is disposed at the air outlet.

[0211] When the air conditioner is running, air is blown out of the air outlet. The air purification component 10 is located at the air outlet, and with the help of the air outlet, the atomized droplets, water, negative ions and hydroxyl radicals generated by the air purification component 10 can be diffused into the indoor environment, thereby humidifying, sterilizing, removing dust and odors in the indoor environment.

[0212] This disclosure provides a household appliance, which includes the air purification device described above.

[0213] The household appliance provided in this embodiment can capture dust, impurities and pathogens in the air by forming charged droplets through the air purification component, and has a certain disinfection effect on pathogens, thereby 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 air purification component is in the form of a sliding arrangement, the distance between the air purification component and the interception net can be adjusted by moving the air purification component, thereby adjusting the humidification rate of the air purification component.
