Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to a purifier. Background Technology

[0002] There are two main types of air purifiers currently available: consumable-type (using HEPA filters, High Efficiency Particulate Air Filters) and consumable-free type (using electro-filtration filters). Both HEPA filters and electro-filtration filters use interception filtration, where dust is trapped inside the filter, making it difficult for users to clean and prone to secondary pollution. Utility Model Content

[0003] The main purpose of this invention is to propose a purifier that is easy to clean, thereby reducing the risk of secondary pollution.

[0004] To achieve the above objectives, this utility model proposes an air purifier, comprising:

[0005] The casing is equipped with a dust collection port;

[0006] A dust collection component is disposed inside the housing. The dust collection surface of the dust collection component is set to be planar. When the dust collection component is energized, it can generate an electric field to adsorb pollutants in the air from the dust collection port through the electric field.

[0007] A cleaning component, located within the housing, is used to clean contaminants from the dust collection component.

[0008] In one embodiment, the housing is provided with a mounting component, the dust collection component is mounted on the mounting component or the base of the housing, and the cleaning component is mounted on the mounting component.

[0009] In one embodiment, the cleaning component includes:

[0010] A driving component is provided on the mounting component;

[0011] A scraping assembly is connected to the driving member, which drives the scraping assembly to reciprocate along the dust collection surface to scrape the dust collection surface.

[0012] In one embodiment, the driving member drives the scraping assembly to reciprocate up and down along the dust collection surface.

[0013] In one embodiment, the driving element includes:

[0014] A rack is provided on the mounting component and extends vertically;

[0015] The gear meshes with the rack;

[0016] An electric motor, the output shaft of which passes through the gear to drive the gear to rotate, so that the gear and the motor reciprocate up and down along the rack;

[0017] A motor mounting bracket is provided, on which both the motor and the scraping assembly are mounted.

[0018] In one embodiment, the motor mounting bracket extends along the length of the dust collection component;

[0019] Two racks, two gears, and two motors are provided. The two racks are located on both sides of the dust collection component in the length direction. Each gear meshes with one rack. The output shaft of each motor passes through one gear. The two motors are located at both ends of the motor mounting bracket.

[0020] In one embodiment, the scraping assembly includes:

[0021] A scraping mounting bracket is provided on the motor mounting bracket;

[0022] A scraping component is provided on the scraping mounting bracket and extends along the length of the dust collection component for scraping the dust collection surface.

[0023] In one embodiment, the scraping assembly further includes:

[0024] A roller is rotatably mounted on the scraping mounting bracket and rolls in contact with the mounting component.

[0025] In one embodiment, the cleaning component further includes a dust collection box located below the dust collection surface for collecting contaminants scraped off by the scraping assembly.

[0026] In one embodiment, a limiting groove is provided on one side of the mounting component, and the dust collection component is mounted in the limiting groove.

[0027] In one embodiment, the dust collection surface protrudes from the limiting groove.

[0028] In one embodiment, the side wall of the dust collection component is provided with a wiring terminal, and the side wall of the limiting groove is provided with a clearance hole, through which the wiring terminal passes.

[0029] In one embodiment, the housing is provided with a discharge port;

[0030] The housing is also equipped with an ion generator, which is used to release ions into the air through the discharge port to charge pollutants in the air. The dust collection component and the ion generator are energized at opposite voltages.

[0031] In one embodiment, the housing includes:

[0032] The base is provided with the discharge port, and the ion generator is disposed inside the base;

[0033] The outer cover has the dust collection port and covers the base. The outer cover and the base enclose a mounting cavity, and the dust collection component and the cleaning component are both installed in the mounting cavity.

[0034] The technical solution of this utility model involves incorporating a dust collection component within the housing. When energized, this component generates an electric field, which is used to adsorb airborne pollutants from the dust collection port of the housing, thereby purifying the air. Because the dust collection surface of the component is planar, airborne pollutants are adsorbed onto the surface via electro-adsorption, preventing them from remaining inside the component. This facilitates cleaning the dust collection component and reduces the risk of secondary pollution.

[0035] Meanwhile, this purifier collects pollutants through an electric field. The collected pollutants are adsorbed onto the dust collection surface of the dust collection component. After use, cleaning or wiping the dust collection surface removes the pollutants, eliminating the need for frequent filter replacements and reducing the purifier's operating costs. With no filters or consumables, it can be repeatedly cleaned and reused, thus solving the pain points of existing purifiers that require frequent filter replacements and are difficult to clean. Furthermore, the dust collection component generates relatively low noise when powered on, enhancing the user experience.

[0036] In addition, the cleaning components can be used to clean contaminants on the dust collection components, thereby achieving automatic cleaning of the dust collection components. This eliminates the need for manual removal and cleaning of the dust collection components, resulting in high cleaning efficiency, reduced labor intensity, and improved user experience.

[0060] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0061] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0062] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0063] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0064] There are two main types of air purifiers currently available: consumable-type (using HEPA filters, High Efficiency Particulate Air Filters) and consumable-free type (using electro-filtration filters). Both HEPA filters and electro-filtration filters use interception filtration, where dust is trapped inside the filter, making it difficult for users to clean and prone to secondary pollution.

[0065] Based on the above problems, this utility model proposes an air purifier 100, aiming to provide an easy-to-clean air purifier 100 to reduce the risk of secondary pollution. The air purifier 100 can be in a vertical form and is equipped with a dust collection component 20 and a cleaning component 30, realizing the functions of air purification and self-cleaning.

[0066] Please see Figures 1 to 6 In one embodiment of the present invention, the purifier 100 includes a housing 10, a dust collection component 20, and a cleaning component 30; the housing 10 is provided with a dust collection port 10a; the dust collection component 20 is disposed inside the housing 10, and the dust collection surface 20a of the dust collection component 20 is set to be planar; the dust collection component 20 can generate an electric field when energized, and is used to adsorb pollutants in the air from the dust collection port 10a through the electric field; the cleaning component 30 is disposed inside the housing 10 and is used to clean the pollutants on the dust collection component 20.

[0067] Understandably, the housing 10 can be a frame structure with an internal mounting cavity, and the dust collection component 20 and the cleaning component 30 are installed in the mounting cavity of the housing 10. The dust collection component 20 can be a plate-shaped structure, with the plate surface facing the dust collection port 10a as the dust collection surface 20a, so that pollutants in the air can be adsorbed from the dust collection port 10a through an electric field, thereby achieving the purpose of air purification.

[0068] In practical applications, the dust collection port 10a can be located on the side or top of the housing 10, as long as it ensures that the dust collection component 20 can adsorb pollutants from the air through the dust collection port 10a via an electric field during use. Of course, in order to provide a larger number of dust collection ports 10a so that the dust collection component 20 can adsorb more pollutants from the air, the dust collection ports 10a can be located on the side of the housing 10.

[0069] It should be noted that the dust collection component 20 generates an electric field after being energized. This electric field forms an electric field region in front of the dust collection surface 20a of the dust collection component 20. Pollutants in the electric field region are polarized. Under the action of Coulomb force, the polarized pollutants move towards the dust collection surface 20a until they are adsorbed onto the dust collection surface 20a. Alternatively, the pollutants in the electric field region are charged and adsorbed onto the dust collection surface 20a. Under this adsorption, the concentration of pollutants in the electric field region decreases. Under the action of concentration difference, pollutants outside the electric field region migrate to the low-concentration electric field region. They can also migrate to the low-concentration electric field region under the action of wind, thereby reducing the concentration of pollutants in the entire environment and achieving the air purification effect.

[0070] In some embodiments, the dust collection component 20 may include two insulating films and a conductive layer sandwiched between the two insulating films. When the conductive layer is energized, it can generate an electric field to adsorb pollutants in the air. The insulating film will not affect the effect of the conductive layer in adsorbing pollutants, but will also provide insulation protection, reduce the failure rate of the dust collection component 20, reduce the possibility of leakage of the dust collection component 20, and avoid the risk of electric shock caused by accidental contact by the user.

[0071] In practical applications, the insulating film can be made of materials such as PC (Polycarbonate), PET (Polyethylene terephthalate), PP (Polypropylene), PTFE (Polytetrafluoroethylene), or PE (Polyethylene). The conductive layer can be made of materials such as ink or copper foil. Optionally, a conductive ink layer can be formed between the two insulating films using screen printing. This method is simple, and the ink is low-cost, has good conductivity, and generates a high electric field strength, enabling better adsorption of pollutants.

[0072] Furthermore, the thickness of the insulating film and conductive layer is not specifically limited here, and can be 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm, etc.

[0073] In practical applications, the cleaning component 30 can automatically clean the dust collection component 20 using methods such as scraping, spraying, air jetting, and adsorption. For example, the cleaning component 30 can use a scraper or a scraper strip 322 to scrape the dust collection surface 20a of the dust collection component 20 to remove contaminants from the surface; alternatively, the cleaning component 30 can use a spray head to spray water onto the dust collection surface 20a of the dust collection component 20, causing the contaminants to flow down with the wastewater; alternatively, the cleaning component 30 can use an air jet head to spray air onto the dust collection surface 20a of the dust collection component 20, causing the contaminants to be sprayed down; alternatively, the cleaning component 30 can use a suction head to adsorb the contaminants from the dust collection surface 20a of the dust collection component 20. Of course, the cleaning component 30 can also use other methods to automatically clean the dust collection component 20, as long as it can effectively clean the dust collection component 20, which will not be elaborated here.

[0074] In summary, the technical solution of this utility model provides a dust collection component 20 inside the housing 10. When energized, the dust collection component 20 generates an electric field, which is used to adsorb airborne pollutants from the dust collection port 10a of the housing 10, thereby purifying the air. Because the dust collection surface 20a of the dust collection component 20 is planar when collecting pollutants, the pollutants in the air are adsorbed onto the dust collection surface 20a by electro-adsorption, preventing them from hiding inside the dust collection component 20. This facilitates cleaning the dust collection component 20 and reduces the risk of secondary pollution.

[0075] Meanwhile, the air purifier 100 collects pollutants through an electric field. The collected pollutants are adsorbed onto the dust collection surface 20a of the dust collection component 20. After use, cleaning or wiping the dust collection surface 20a removes the pollutants, eliminating the need for frequent filter replacements and reducing the operating cost of the air purifier 100. With no filters or consumables, it can be repeatedly cleaned and reused, thus solving the pain points of existing air purifiers 100 that require frequent filter replacements and are difficult to clean. Furthermore, the dust collection component 20 generates relatively low noise when powered on, enhancing the user experience.

[0076] In addition, the cleaning component 30 can be used to clean contaminants on the dust collection component 20, thereby achieving automatic cleaning of the dust collection component 20. It eliminates the need for manual removal and cleaning of the dust collection component 20, resulting in high cleaning efficiency, reduced labor intensity, and improved user experience.

[0077] The pollutants mentioned in this application are mainly particulate pollutants, including dust, smoke, particulate matter, bacteria, and viruses in the air. They vary in diameter and can generally be classified into the following categories according to their diameter:

[0078] Visible particulate matter: Particulate matter with a diameter of 10 micrometers or less can be seen, such as dust, pollen, and human skin flakes.

[0079] Fine particulate matter: Particulate matter with a diameter of 2.5 micrometers or less, which cannot be seen with the naked eye, but has a significant impact on human health, such as automobile exhaust and factory exhaust.

[0080] Ultrafine particles: Particles with a diameter of 0.1 micrometers or less, which cannot be seen with the naked eye, but can penetrate deep into the human respiratory tract and have a greater impact on human health, such as viruses and bacteria.

[0081] Please see Figure 2 , Figure 4 In one embodiment of the present invention, the housing 10 is provided with an installation component 40, the dust collection component 20 is installed on the installation component 40 or the base 11 of the housing 10, and the cleaning component 30 is installed on the installation component 40.

[0082] This configuration, by mounting the dust collection component 20 on the mounting component 40 or the base 11 of the housing 10, and mounting the cleaning component 30 on the mounting component 40, makes it easier to disassemble and assemble the housing 10, so as to facilitate the disassembly and maintenance of the dust collection component 20 and the cleaning component 30.

[0083] In practical applications, the mounting component 40 can be a mounting plate, or a component in the shape of a mounting block, mounting strip, etc., as long as it can be used to mount the dust collection component 20 and the cleaning component 30. No specific limitation is made here.

[0084] Furthermore, the mounting component 40 can be installed inside the housing 10 using methods such as plug-in, screw connection, or snap-fit ​​to ensure the installation reliability of the mounting component 40. Similarly, the dust collection component 20 and the cleaning component 30 can also be installed on the mounting component 40 using methods such as plug-in, screw connection, or snap-fit ​​to ensure the installation reliability of the dust collection component 20 and the cleaning component 30.

[0085] In one embodiment, when the housing 10 includes a base 11 and an outer cover 12, a slot may be provided on the top of the base 11 and a plug may be provided on the bottom of the mounting component 40. The mounting component 40 can be installed by inserting the plug of the mounting component 40 into the slot of the base 11.

[0086] Please see Figure 2 , Figure 4 In one embodiment of the present invention, the cleaning component 30 includes a driving component 31 and a scraping component 32; the driving component 31 is disposed on the mounting component 40; the scraping component 32 is throttle-connected to the driving component 31, and the driving component 31 drives the scraping component 32 to reciprocate along the dust collection surface 20a to scrape the dust collection surface 20a.

[0087] With this configuration, the scraping assembly 32 is driven by the drive component 31 to reciprocate along the dust collection surface 20a, thereby scraping off the contaminants on the dust collection surface 20a and achieving self-cleaning of the dust collection component 20. In addition, compared with cleaning methods such as spraying, air jetting, and adsorption, the scraping cleaning method is not only cheaper but also easier to collect contaminants.

[0088] In practical applications, the drive component 31 can drive the scraping component 32 to perform reciprocating up-and-down motion along the dust collection surface 20a, or it can drive the scraping component 32 to perform reciprocating horizontal motion along the dust collection surface 20a. As long as the pollutants on the dust collection surface 20a can be scraped off during the reciprocating motion, it is acceptable.

[0089] Furthermore, the drive component 31 can be a structure in which the motor 313 and the lead screw and nut cooperate, or a structure in which the motor 313 and the gear 312 and the rack 311 cooperate, or a structure in which the motor 313 and the synchronous belt cooperate, or a linear motor 313, as long as it can drive the scraping component 32 to perform reciprocating motion.

[0090] Please see Figures 6 to 12 In one embodiment of this utility model, the driving component 31 drives the scraping assembly 32 to reciprocate up and down along the dust collection surface 20a.

[0091] With this configuration, the scraping assembly 32 is driven by the drive component 31 to repeatedly scrape the dust collection surface 20a of the dust collection component 20 by reciprocating up and down. This not only makes the movement stability of the scraping assembly 32 more reliable, but also scrapes the pollutants off to the dust collection structure for collection.

[0092] In practical applications, the driving component 31 can be set on the front side of the dust collection component 20, or on the left and right sides of the dust collection component 20, or on the rear side of the dust collection component 20, as long as the driving component 31 can drive the scraping component 32 to reciprocate up and down along the dust collection surface 20a.

[0093] Please see Figures 13 to 19 In one embodiment of this utility model, the driving component 31 includes a rack 311, a gear 312, a motor 313, and a motor mounting bracket 314; the rack 311 is disposed on the mounting component 40 and extends vertically; the gear 312 meshes with the rack 311; the output shaft of the motor 313 passes through the gear 312 to drive the gear 312 to rotate, so that the gear 312 and the motor 313 reciprocate up and down along the rack 311; the motor 313 and the scraping assembly 32 are both mounted on the motor mounting bracket 314.

[0094] With this configuration, the rack 311 is fixed to the mounting component 40, the motor 313 is supported on the rack 311 via the gear 312, and the motor mounting bracket 314 is supported on the motor 313. Thus, when the motor 313 is working, it can drive the gear 312 to rotate via its output shaft. Under the meshing of the gear 312 and the rack 311, the gear 312 can reciprocate up and down along the rack 311, causing the motor 313, the motor mounting bracket 314, and the scraping assembly 32 to all reciprocate up and down with the gear 312. By using the gear 312 and rack 311 to drive the scraping assembly 32 up and down, higher precision and more reliable stability can be achieved.

[0095] In this embodiment, the motor 313 and the gear 312 can be respectively disposed on both sides of the motor mounting bracket 314. The output shaft of the motor 313 can pass through the motor mounting bracket 314 and pass through the gear 312. Optionally, in order to improve the installation reliability between the motor 313 and the motor mounting bracket 314, a bearing can be provided on the motor mounting bracket 314 so that the output shaft of the motor 313 passes through the bearing of the motor mounting bracket 314.

[0096] In practical applications, rack 311, gear 312 and motor 313 can each be provided with one, or at least two, depending on the actual usage.

[0097] Please see Figure 18 , Figure 19 In one embodiment of this utility model, the motor mounting bracket 314 extends along the length direction of the dust collection component 20; two racks 311, two gears 312, and two motors 313 are provided. The two racks 311 are located on both sides of the dust collection component 20 in the length direction. Each gear 312 meshes with one rack 311. The output shaft of each motor 313 passes through one gear 312. The two motors 313 are respectively located at both ends of the motor mounting bracket 314.

[0098] With this configuration, two racks 311 are provided on both sides of the dust collection component 20 along its length, and two gears 312 are respectively engaged with the two racks 311. Two motors 313 are used to drive the two gears 312 to rotate. This can effectively support both ends of the motor mounting bracket 314, thereby improving the stability of the motor mounting bracket 314 during the reciprocating lifting process, and thus driving the scraping component 32 to lift more smoothly.

[0099] Please see Figure 14 , Figure 15In one embodiment of the present invention, the scraping assembly 32 includes a scraping mounting bracket 321 and a scraping component 322; the scraping mounting bracket 321 is disposed on the motor mounting bracket 314; the scraping component 322 is disposed on the scraping mounting bracket 321 and extends along the length direction of the dust collection component 20 for scraping the dust collection surface 20a.

[0100] This configuration, where the scraper 322 is mounted on the motor mounting bracket 314 via the scraper mounting bracket 321, improves the reliability of the scraper 322's installation and facilitates its installation. Furthermore, by extending the scraper 322 along the length of the dust collection component 20, it can scrape various positions on the dust collection surface 20a during its reciprocating lifting and lowering process, ensuring thorough cleaning of all areas and enhancing the cleaning effect on the dust collection surface 20a.

[0101] In practical applications, the scraper mounting bracket 321 can be installed on the motor mounting bracket 314 using methods such as screw connection, snap-fit, adhesive bonding, or adsorption. Similarly, the scraper component 322 can also be installed on the scraper mounting bracket 321 using methods such as screw connection, snap-fit, adhesive bonding, or adsorption.

[0102] In practical applications, the scraping component 322 can be a scraper, scraper blade, brush, towel, or other structural component, as long as it can smoothly scrape off the contaminants on the dust collection surface 20a during the reciprocating motion. No specific limitation is made here.

[0103] Please see Figure 14 , Figure 15 , Figure 19 In one embodiment of the present invention, the scraping assembly 32 further includes a roller 323, which is rotatably disposed on the scraping mounting bracket 321 and rolls in contact with the mounting component 40.

[0104] With this configuration, during the reciprocating lifting and lowering of the scraping assembly 32, the roller 323 can roll into contact with the mounting component 40. The design of the roller 323 can reduce the driving resistance of the drive component 31 on the scraping assembly 32, enabling the scraping assembly 32 to achieve smooth lifting and lowering.

[0105] In this embodiment, a mounting groove may be provided on the side of the scraping mounting bracket 321 near the mounting component 40, and the roller 323 may be rotatably mounted in the mounting groove, with the outer side of the roller 323 protruding from the side of the scraping mounting bracket 321 near the mounting component 40.

[0106] In some embodiments, please refer to Figure 16In order to improve the stability of the rolling engagement between the roller 323 and the mounting component 40, a matching track can be provided on the side of the mounting component 40 near the scraping mounting bracket 321 so that the roller 323 can roll up and down within the matching track.

[0107] In practical applications, one or two rollers 323 can be provided, depending on the actual usage. Optionally, at least one roller 323 can be provided on both sides of the scraping mounting bracket 321.

[0108] Please see Figures 6 to 12 In one embodiment of the present invention, the cleaning component 30 further includes a dust collection box 33, which is located below the dust collection surface 20a and is used to collect contaminants scraped off by the scraping component 32.

[0109] With this configuration, as the drive component 31 drives the scraping assembly 32 to reciprocate, it can scrape off the contaminants on the dust collection surface 20a. The scraped-off contaminants can fall into the dust collection box 33 for collection. Users can then periodically remove the dust collection box 33 for cleaning.

[0110] In some embodiments, the dust collection box 33 may include a dust collection part 331 and a pull-out part 332. The top of the dust collection part 331 is provided with an opening, which is located directly below the dust collection surface 20a. The pull-out part 332 is connected to the dust collection part 331. When the user disassembles or installs the dust collection box 33, the dust collection box 33 can be pulled out through the pull-out part 332 or pushed into the installation position, which makes it easier to disassemble and install the dust collection box 33.

[0111] Optionally, the bottom of the pull-out section 332 is provided with a handle so that the user can pull out or push in the dust collection box 33 by using the handle.

[0112] In some embodiments, in order to improve the installation reliability of the dust collection box 33 and prevent the dust collection box 33 from shaking inside the housing 10 during the transportation of the purifier 100, a limiting slot can be provided inside the housing 10 to install the dust collection box 33 in the limiting slot for limiting and fixing the dust collection box 33.

[0113] Please see Figure 2 , Figure 4 In one embodiment of the present invention, a limiting groove 41 is provided on one side of the mounting component 40, and the dust collection component 20 is mounted in the limiting groove 41.

[0114] With this configuration, by installing the dust collection component 20 in the limiting groove 41 of the mounting component 40, the dust collection component 20 is limited and fixed by the limiting groove 41. This not only ensures the installation reliability of the dust collection component 20, but also facilitates the disassembly and replacement of the dust collection component 20.

[0115] In practical applications, the cross-section of the dust collection component 20 can be rectangular, circular, elliptical, or other shapes. Correspondingly, the cross-section of the limiting groove 41 is designed to match the cross-section of the dust collection component 20.

[0116] In some embodiments, please refer to Figure 16 To facilitate the installation of the dust collection component 20 in the limiting groove 41, the mounting component 40 can include a mounting body and a mounting cover. When the mounting cover is placed on the mounting body, it can enclose and form the limiting groove 41. In this way, the dust collection component 20 can be inserted into the limiting groove 41 from the top of the mounting body first, and then the mounting cover can be placed on the mounting base plate to limit and fix the dust collection component 20 in the limiting groove 41.

[0117] Please see Figure 4 In one embodiment of this utility model, the dust collection surface 20a protrudes from the limiting groove 41.

[0118] With this design, the dust collection surface 20a of the dust collection component 20 protrudes out of the limiting groove 41, making it easier to clean the dust collection surface 20a by the cleaning component 30. At the same time, it allows the cleaned contaminants to fall into the dust collection box 33 below, thus avoiding the contaminants falling into the limiting groove 41 and requiring subsequent manual cleaning.

[0119] Please see Figure 2 In one embodiment of the present invention, the side wall of the dust collection component 20 is provided with a wiring terminal 21, and the side wall of the limiting groove 41 is provided with a clearance hole 42, through which the wiring terminal 21 passes.

[0120] This configuration allows the terminals of the dust collection component 20 to pass through the clearance hole 42 of the mounting component 40, facilitating the connection of the dust collection component 20 to an external power supply device and enabling power supply to the dust collection component 20.

[0121] In addition, the cooperation between the wiring terminal 21 and the clearance hole 42 can further limit and fix the dust collection component 20, thereby improving the limiting and fixing effect of the dust collection component 20.

[0122] In practical applications, the number of clearance holes 42 and terminals 21 can be one or two, depending on the actual usage.

[0123] Please see Figure 2 In one embodiment of this utility model, the housing 10 can be equipped with a discharge port 10b; the housing 10 is also provided with an ion generator 50, which is used to release ions into the air through the discharge port 10b to charge pollutants in the air. The dust collection component 20 and the ion generator 50 have opposite energizing voltages.

[0124] With this configuration, the ions generated by the ion generator 50 are released into the air through the discharge port 10b. The ions attach to pollutants in the air, making the pollutants charged. Since the voltage of the dust collection component 20 is opposite to that of the ion generator 50, the pollutants can be charged with the opposite charge to the dust collection component 20, thereby accelerating the movement of the pollutants toward the dust collection surface 20a of the dust collection component 20. This achieves the technical effect of improving the adsorption capacity of the dust collection component 20 and enhancing the air purification capacity and efficiency.

[0125] At the same time, the ions released by the ion generator 50 can also sterilize and reduce the content of toxic substances in the air to protect the health of users.

[0126] It should be noted that when the ion generator 50 emits negative ions, the dust collection component 20 is supplied with a positive DC high voltage; when the ion generator 50 emits positive ions, the dust collection component 20 is supplied with a negative DC high voltage.

[0127] In this embodiment, one of the positive and negative terminals on the power supply component can be connected to the dust collection component 202, and the other can be electrically connected to the ion generator 50, so that the polarity of the ions accumulated on the dust collection component 20 and the ions released by the ion generator 50 are opposite.

[0128] In practical applications, the discharge port 10b can be located on the side or top of the housing 10. Alternatively, in order to enable the ions released from the discharge port 10b to be better adsorbed onto air pollutants, the discharge port 10b can be located on the side of the housing 10 and near the bottom of the housing 10.

[0129] Furthermore, the discharge port 10b can be elongated, circular, elliptical, triangular, or other shapes, without any specific limitation.

[0130] In some embodiments, a fan may be provided inside the housing 10. When the fan is working, it can generate a directional airflow, which can drive the electro-ions generated by the ion generator 50 to diffuse into the air, so that more pollutants in the air are attached by the electro-ions. It can also drive the charged pollutants in the air to move towards the dust collection component 20, thereby accelerating the airflow around the purifier 100. Thus, together with the dust collection component 20 and the ion generator 50, the air purification capacity can be improved. At the same time, the directional electro-ions can sterilize the pollutants in the airflow, thereby reducing the content of toxic substances in the air and protecting the health of users.

[0131] In some embodiments, the ion generator 50 may include a high-voltage transformer 51 and an emitter 52. The high-voltage transformer 51 supplies power to the emitter 52 so that the emitter 52 generates ions corresponding to the electrodes and sprays the ions into the air through the discharge port 10b. This allows the ions to be sprayed into the air in a larger area near the purifier 100, thereby improving the air purification effect.

[0132] In this embodiment, the high-voltage pack 51 can be either a negative high-voltage pack 51 or a positive high-voltage pack 51. When the dust collection component 20 is supplied with positive DC high voltage, the high-voltage pack 51 of the ion generator 50 is a negative high-voltage pack 51; when the dust collection component 20 is supplied with negative DC high voltage, the high-voltage pack 51 of the ion generator 50 is a negative high-voltage pack 51.

[0133] In some embodiments, multiple discharge ports 10b can be provided along the length direction of the housing 10, and multiple emitters 52 can be provided. The multiple emitters 52 are distributed at intervals along the extension direction of the housing 10. In this way, multiple emitters 52 can simultaneously spray ions into the air, thereby generating more ions so that more pollutants in the air are attached with ions, thereby improving the air purification efficiency and purification effect.

[0134] Please see Figure 2 In one embodiment of the present invention, the housing 10 includes a base 11 and an outer cover 12; the base 11 is provided with a discharge port 10b, and the ion generator 50 is disposed inside the base 11; the outer cover 12 is provided with a dust collection port 10a and is disposed on the base 11, and the outer cover 12 and the base 11 enclose a mounting cavity, in which the dust collection component 20 and the cleaning component 30 are both installed.

[0135] This design makes it easier to install the dust collection component 20, the cleaning component 30, and the mounting component 40 inside the housing 10. First, the mounting component 40 can be installed on the base 11. Then, the dust collection component 20 and the cleaning component 30 can be installed on the mounting component 40. Finally, the outer cover 12 can be placed over the base 11. Furthermore, when maintenance or replacement of the dust collection component 20 or the cleaning component 30 is required, the outer cover 12 can be directly removed, further facilitating maintenance and replacement of the dust collection component 20 or the cleaning component 30.

[0136] In practical applications, the outer cover 12 and the base 11 can be connected by means of interference fit, snap-fit, screw connection, etc.

[0137] In one embodiment, since the purifier 100 can be vertical, to ensure its stability during use, the cross-sectional area of ​​the base 11 can be larger than that of the outer cover 12, resulting in a shape that is larger at the bottom and smaller at the top, thus preventing the purifier 100 from tipping over. Furthermore, to prevent dirt from accumulating on the top of the base 11 exposed outside the outer cover 12, the top of the base 11 exposed outside the outer cover 12 can be designed with an inclined surface, and the discharge port 10b is located on this inclined surface.

[0138] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
