Technical Field

[0001] This utility model relates to the field of air purification technology, and specifically to an improvement in the structure of an air purification device. Background Technology

[0002] Existing air purification ion generators contain internal emitting electrodes for ionizing air to produce plasma. These electrodes are typically fixed in position and cannot be moved. Consequently, once manufactured, the ion generator can only produce a fixed type of ion, such as fixed negative ions, positive and negative ions, or plasma. However, different ions have different purification capabilities for different pollutants. When using a single type of ion generated by the emitting electrode to sterilize or remove pollutants, the limited variety restricts its sterilization or purification capabilities, resulting in poor effectiveness against various pollutants.

[0034] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0035] In some embodiments of this application, an air purification device is proposed, with reference to Figures 1-2 As shown, it mainly comprises a housing 100, a first discharge electrode 200 and a second discharge electrode 300 arranged inside the housing 100, an electrode power supply unit 400 that provides output voltage to the first discharge electrode 200 and the second discharge electrode 300, and a spacing adjustment device 500 that adjusts the electrode spacing.

[0036] The housing 100 is used to form the outer shell of the entire air purification device, and is used to house and assemble the first discharge electrode 200, the second discharge electrode 300, the electrode power supply unit 400, and the spacing adjustment device 500.

[0037] The first discharge electrode 200 is fixedly disposed inside the housing 100.

[0038] The first discharge electrode 200 is fixed in position within the housing 100, and the first discharge electrode 200 has a first tip.

[0039] The first tip is a tapered needle with a gradually decreasing outer diameter. The tip of the needle can form the discharge point where the first discharge electrode 200 discharges when a voltage is applied to the first discharge electrode 200.

[0040] In some embodiments of this application, at least one of the first discharge electrode 200 and the second discharge electrode 300 is a carbon fiber porous water-absorbing electrode. Noble metals and transition metal oxides can be coated inside the electrode as electrocatalysts to promote the generation of highly efficient active substances—hydroxyl radicals, thereby improving the purification capacity for gaseous pollutants such as TVOC and formaldehyde.

[0041] Precious metals can include gold, silver, platinum, etc.

[0042] Reference Figures 1-2As shown, the second discharge electrode 300 is movably disposed within the housing 100, and is positioned opposite to the first discharge electrode 200. There is a gap D between the second discharge electrode 300 and the first discharge electrode 200.

[0043] The second discharge electrode 300 has a second tip.

[0044] The second tip is a tapered needle with a gradually decreasing outer diameter. The tip of the needle can form a discharge point where the second discharge electrode 300 discharges when a voltage is applied to the second discharge electrode 300.

[0045] Since the second discharge electrode 300 is movably disposed within the housing 100, the distance D between the second discharge electrode 300 and the first discharge electrode 200 can be changed when it moves relative to the housing 100.

[0046] The electrode power supply unit 400 supplies a first voltage and a second voltage to the first discharge electrode 200 and the second discharge electrode 300 respectively, and the first voltage and the second voltage have a voltage difference.

[0047] In the embodiments of this application, the electrode power supply unit 400 is a high-voltage transformer, which can be used to simultaneously supply a first voltage and a second voltage with a voltage difference to the first discharge electrode 200 and the second discharge electrode 300.

[0048] Because there is a voltage difference between the first voltage and the second voltage, an electric field will be formed between the first discharge electrode 200 and the second discharge electrode 300 when the first voltage and the second voltage are input to the first discharge electrode 200 and the second discharge electrode 300.

[0049] When the distance D between the first discharge electrode 200 and the second discharge electrode 300 is relatively far, the electric field strength between the two electrodes is relatively weak, the mutual influence between the two electrodes is relatively small, and at least one of the two electrodes is mainly responsible for ionizing the air around it.

[0050] When the distance D between the first discharge electrode 200 and the second discharge electrode 300 is close, a potential difference will be generated between the two electrodes, resulting in a strong electric field between them. The air between the two electrodes will be instantaneously ionized to generate plasma. That is, the moisture on the two electrodes and the moisture in the air will be ionized by the strong electric field to generate hydroxyl radicals •OH. The oxygen in the air will also be ionized and excited to generate ozone. Plasma, plasma + ozone + hydroxyl radicals are all strong oxidizing substances, which can kill bacteria on the surface of objects and oxidize and decompose volatile organic compounds (VOCs) in the air, thereby achieving the purpose of purifying gaseous pollutants.

[0051] When the distance D between the two electrodes is further reduced, the electric field strength between the two electrodes is further increased. The electric field energy is mainly used to generate highly oxidizing hydroxyl radicals, O3, ion clusters and excited-state molecules. At this time, the air becomes plasma, the positive and negative charges are balanced, and it is difficult to release negative ions outward. The highly oxidizing ions can kill bacteria.

[0052] In some embodiments of this application, the air purification device includes a spacing adjustment device 500 connected to the second discharge electrode 300, for driving the second discharge electrode 300 to move relative to the housing 100 to change the spacing between the first discharge electrode 200 and the second discharge electrode 300.

[0053] The spacing adjustment device 500 is connected to the second discharge electrode 300. When it is activated, it can move the second discharge electrode 300 to change its position, thereby changing the spacing between the first discharge electrode 200 and the second discharge electrode 300.

[0054] The above embodiments have the following advantages and effects: In this embodiment, the air purification device has a first discharge electrode 200 and a second discharge electrode 300 arranged opposite to each other. The second discharge electrode 300 is movable and connected to a spacing adjustment device 500. In use, the spacing adjustment device 500 can be controlled to move the second discharge electrode 300 to change its position, thereby changing the spacing between the first discharge electrode 200 and the second discharge electrode 300. By adjusting the spacing between the two electrodes, different types of ions can be generated, ensuring that the required types of ions can be generated according to actual usage needs, thus achieving a more intelligent and comprehensive purification capability.

[0055] In some embodiments of this application, the first discharge electrode 200 is a positive high-voltage electrode or a ground electrode, and the second discharge electrode 300 is a negative high-voltage electrode.

[0056] When the first discharge electrode 200 is a positive high-voltage electrode or a ground electrode, its voltage is higher than that of the second discharge electrode 300. A voltage difference will be formed between it and the negative high-voltage second discharge electrode 300. An electric field for ionizing air can be formed between the first discharge electrode 200 and the second discharge electrode 300.

[0057] In some embodiments of this application, the first discharge electrode 200 is a negative high-voltage electrode, and the second discharge electrode 300 is a positive high-voltage electrode or a ground electrode.

[0058] When the second discharge electrode 300 is a positive high-voltage electrode or a ground electrode and the first discharge electrode 200 is a negative high-voltage electrode, a pressure difference and an electric field can be formed between the two.

[0059] When the distance between the first discharge electrode 200 and the second discharge electrode 300 is relatively large, and one electrode is a positive high voltage electrode and the other electrode is a negative high voltage electrode, the negative high voltage electrode will generate a large number of negative ions, and the positive high voltage electrode will generate positive ions. The positive and negative ions are released into the air in large quantities, which adsorb, agglomerate and settle pollutants such as bacteria, viruses and particulate matter in the air to the ground, thereby purifying the air.

[0060] When the distance between the first discharge electrode 200 and the second discharge electrode 300 is relatively large, and one electrode is a ground electrode and the other is a negative high-voltage electrode, the negative high-voltage electrode will generate a large number of negative ions, the ground electrode will not ionize the air, and a large number of negative ions will be released into the air to sterilize pollutants such as bacteria, viruses and particulate matter in the air.

[0061] When the distance D between two electrodes is close, and one electrode is a positive high-voltage electrode or a ground electrode, while the other electrode is a negative high-voltage electrode, a high-voltage electric field will be generated between the two electrodes, causing the air between the two electrodes to be instantaneously ionized, thus generating plasma.

[0062] When the distance D between the two electrodes is closer, and one electrode is a positive high-voltage electrode or a ground electrode, while the other electrode is a negative high-voltage electrode, a stronger high-voltage electric field will be generated between the two electrodes. This will cause the air between the two electrodes to be ionized instantaneously, producing a large amount of ozone, hydroxyl radicals, and other strong oxidizing substances.

[0063] The above embodiments have the following advantages and effects: When setting the electrode structure, the first discharge electrode 200 can be set as an electrode with a higher input voltage, such as a positive high voltage electrode or a ground electrode, and the second discharge electrode 300 can be set as an electrode with a lower input voltage. Alternatively, the first discharge electrode 200 can be set as an electrode with a lower input voltage, and the second discharge electrode 300 can be set as an electrode with a higher input voltage. As long as there is a voltage difference between the two electrodes, the two electrode settings can be diversified.

[0064] In some embodiments of this application, reference is made to Figure 3 , 4 As shown, a slide 110 is formed on the housing 100; The electrode substrate 600 includes: a slider portion 610 arranged in the slide rail 110 and slidingly engaged with the slide rail 110; and the second discharge electrode 300 is mounted on the electrode substrate 600.

[0065] The electrode substrate 600 forms the electrode support of the second discharge electrode 300, thereby supporting and fixing the second discharge electrode 300.

[0066] Reference Figure 9As shown, the slide 110 is formed by a first slide member and a second slide member.

[0067] The first slide rail component is located at the bottom of the housing 100; The second slide rail component has two sections connected to both sides of the first slide rail component. The second slide rail component includes a vertical section and a transverse section that bends from the vertical section. The two transverse sections of the two second slide rail components are arranged opposite each other and have openings.

[0068] The slider part 610 is adapted to the shape of the slide rail 110 and is inserted into the slide rail 110. The width of the slider part 610 is greater than the opening, and it is limited by the lateral section to prevent it from disengaging from the slide rail 110.

[0069] The above embodiments have the following advantages and effects: The slider 610 on the electrode substrate 600 is slidably connected to the slide rail 110 of the housing 100, which can drive the second discharge electrode 300 mounted on it to move relative to the housing 100 and change its position, thereby changing the distance between the second discharge electrode 300 and the first discharge electrode 200.

[0070] In some embodiments of this application, reference is made to Figure 7 As shown, the air purification device includes a conductive component 700 connected between the second discharge electrode 300 and the electrode power supply unit 400, for transmitting the voltage of the electrode power supply unit 400 to the second discharge electrode 300.

[0071] The conductive component 700 has a conductive function and is connected between the second discharge electrode 300 and the electrode power supply unit 400, which can conduct the voltage output by the electrode power supply unit 400 to the second discharge electrode 300.

[0072] In some embodiments of this application, reference is made to Figure 7 As shown, the conductive component 700 includes: The first conductive element 710 is assembled inside the electrode substrate 600 and connected to the second discharge electrode 300.

[0073] The first conductive element 710 is a conductive needle with a pointed tip, which is mainly used to fix the second discharge electrode 300. Since the second discharge electrode 300 is made of carbon fiber material, when the second discharge electrode 300 is assembled with the conductive needle, the pointed tip of the conductive needle is inserted into the second discharge electrode 300 to achieve insertion and fixation.

[0074] The second conductive element 720 is electrically connected to the electrode power supply unit 400, is arranged in the slide rail 110 and extends along the length of the slide rail 110, and maintains contact with the first conductive element 710 when the first conductive element 710 slides.

[0075] A locking groove 111 is provided on both sides of the slide 110. The conductive component 700 is locked in the locking groove 111 and fixed to the slide 110. When the electrode substrate 600 drives the first conductive component 710 to slide relative to the housing 100, the second conductive component 720 does not move, and the first conductive component 710 moves along the second conductive component 720.

[0076] By arranging the second conductive element 720 to extend along the length of the slide rail 110, it can be ensured that when the first conductive element 710 is driven by the electrode substrate 600 to slide along the slide rail 110, it is located on the sliding path of the first conductive element 710 and can always maintain contact with the first conductive element 710 to ensure conductivity.

[0077] The air purification device includes an electronic control unit, which includes the electrode power supply unit 400. When the second discharge electrode 300 is a positive high voltage electrode, the electrode power supply unit 400, i.e., the high voltage transformer, can boost the weak current to a positive high voltage, such as boosting the 12V weak current to a positive high voltage of 2±1KV. The positive high voltage is transmitted to the first conductive element 710 through the second conductive element 720, and the first conductive element 710 transmits the positive high voltage to the second discharge electrode 300.

[0078] The above embodiments have the following advantages and effects: By configuring the conductive component 700 as a first conductive component 710 mounted on the electrode substrate 600 and connected to the second discharge electrode 300, and a second conductive component 720 extending along the length direction of the slide rail 110 and connected to the electrode power supply unit 400, it can be ensured that when the first conductive component 710 is moved by the electrode substrate 600, it can always be in contact with the second conductive component 720 arranged in the direction of the slide rail 110 for conduction.

[0079] In some embodiments of this application, reference is made to Figure 10 As shown, the second conductive element 720 is elastic and includes: A second conductive surface 721 is provided protruding to one side of the first conductive element 710; The first conductive element 710 is provided with a first conductive surface 711, and the first conductive surface 711 and the second conductive surface 721 are adapted in shape.

[0080] By providing a second conductive surface 721 on the second conductive element 720 that protrudes toward the first conductive element 710, and a first conductive surface 711 on the first conductive element 710 that matches it, it is possible to ensure a tight fit between the first conductive element 710 and the second conductive element 720, thus ensuring conductivity.

[0081] The second conductive element 720 is a conductive plate made of an elastic metal material. While ensuring conductivity, it also has a certain amount of elastic deformation, so that it can maintain close contact with the first conductive element 710.

[0082] In some embodiments, the first conductive surface 711 is a first arc-shaped surface, the second conductive surface 721 is a second arc-shaped surface, and the second arc-shaped surface and the first arc-shaped surface are interference-fitted.

[0083] In some embodiments of this application, reference is made to Figure 5 , 6 As shown in Figure 8, the electrode substrate 600 includes: The base portion 620 is connected to the slider portion 610 via the connecting portion 630 and is located outside the slide rail 110. An assembly portion 640 is formed on the base portion 620. An electrode mounting portion 641 for mounting the emitting electrode is formed on the assembly portion 640. A conductive component mounting portion 650 for mounting the first conductive component 710 is formed between the assembly portion 640, the connecting portion 630 and the slider portion 610.

[0084] The width of the connecting part 630 is adapted to the width of the opening. It is inserted into the opening position, with one end connected to the base part 620 and the other end connected to the slider part 610.

[0085] The assembly part 640 is an assembly base part formed at one end of the base part 620, and the electrode mounting part 641 is an electrode mounting hole formed on the assembly part 640 with an open top.

[0086] The conductive component mounting portion 650 is a conductive component mounting hole that extends downward from the assembly portion 640 and sequentially passes through the bottom wall of the assembly portion 640, the connecting portion 630, and the slider portion 610.

[0087] The electrode mounting holes and conductive component mounting holes are arranged sequentially from top to bottom along the height direction of the assembly part 640 and are interconnected, ensuring that the first conductive component 710 can be inserted into the electrode mounting hole and assembled with the second discharge electrode 300.

[0088] The electrode mounting hole is used to insert the second discharge electrode 300. The inner diameter and shape of the electrode mounting hole are adapted to the outer diameter and external shape of the second discharge electrode 300 to achieve support and fixation of the second discharge electrode 300.

[0089] The shape of the mounting hole for the conductive component is adapted to the shape and size of the first conductive component 710 to support and fix the first conductive component 710.

[0090] When the second discharge electrode 300 and the electrode substrate 600 are assembled, the slider portion 610 on the electrode substrate 600 is inserted into the slide 110 from one end of the slide 110 to achieve a sliding connection between the electrode substrate 600 and the slide 110.

[0091] When the first conductive element 710 is assembled, it is inserted into the conductive element mounting hole from below the electrode base 600 with its tip facing upward. When the first conductive element 710 is inserted into place, at least a portion of its tip extends into the electrode mounting hole, and its bottom abuts against the second conductive element 720 fixed in the slide rail 110.

[0092] When assembling the second discharge electrode 300, it is inserted from above into the electrode mounting hole in the assembly part 640, and simultaneously inserted into the tip portion extending into the electrode mounting hole. Since the second discharge electrode 300 is made of carbon fiber material, after the tip portion of the first conductive member 710 is inserted into the second discharge electrode 300, it will be stretched outward and then tightly fitted with the inner wall of the electrode mounting hole, thereby achieving fixation with the electrode substrate 600.

[0093] The above embodiments have the following advantages and effects: By arranging the slider portion 610, the connecting portion 630, and the assembly portion 640 on the electrode substrate 600, not only is the sliding connection between the electrode substrate 600 and the housing 100 realized, but also the assembly of the first conductive element 710 and the second discharge electrode 300 is realized, thus achieving the integrated configuration of the electrode substrate 600 structure.

[0094] In some embodiments of this application, reference is made to Figure 6 As shown, the electrode substrate 600 includes a rack portion 660 formed on the substrate portion 620. The rack portion 660 is a rack formed on the substrate portion 620 and is arranged along the length direction of the substrate portion 620.

[0095] The spacing adjustment device 500 includes: Drive component 510, and The drive gear section 520 is connected to the drive component 510 and the rack section 660 in a transmission connection.

[0096] The drive component 510 is a drive motor, which is fixed inside the housing 100 by a motor bracket and has an output shaft. The drive gear part 520 is a drive gear mounted on the output shaft, and the drive gear meshes with the rack.

[0097] The above embodiments have the following advantages and effects: By engaging the drive gear portion 520 provided on the drive component 510 with the rack portion 660 formed on the electrode substrate 600, when the drive component 510 rotates, the drive gear portion 520 can be driven to rotate, thereby driving the rack portion 660 that engages with it to move linearly, and driving the electrode substrate 600 and the second discharge electrode 300 mounted on it to move linearly.

[0098] In some embodiments of this application, reference is made to Figure 4 As shown, it includes: an electrode mounting base 120, which is fixed inside the housing 100, and a first discharge electrode mounting part 121 is provided on the electrode mounting base 120.

[0099] The first discharge electrode mounting part 121 is a mounting hole for the first discharge electrode 200 opened in the electrode mounting base 120, which is used to insert and fix the first discharge electrode 200.

[0100] A potting cavity 130 is formed inside the housing 100 and is used to arrange the power supply line of the first discharge electrode 200. It is connected to the first discharge electrode mounting part 121 and potting glue is filled in the potting cavity 130.

[0101] The power supply line of the first discharge electrode 200 led out from the electrode power supply unit 400 is laid in the potting cavity 130 and is connected to the first discharge electrode mounting part 121, which can ensure that the power supply line of the first discharge electrode 200 can enter the first discharge electrode mounting part 121 through the potting cavity 130 and be electrically connected to the first discharge electrode 200.

[0102] The power supply line can be sealed by filling the potting compound into the potting cavity 130.

[0103] Epoxy resin potting compound can be used.

[0104] The above embodiments have the following advantages and effects: The first discharge electrode 200 can be installed and fixed by the electrode mounting base 120 provided in the housing 100 and the first discharge electrode mounting part 121 arranged above it. The potting cavity 130 provided and connected to the first discharge electrode mounting part 121 can ensure the laying of the power supply line and the electrical connection with the first discharge electrode 200, and ensure that the voltage can be delivered to the first discharge electrode 200.

[0105] In some embodiments of this application, reference is made to Figure 2 As shown, the air purification device includes a partition 140 disposed inside the housing 100, which divides the housing 100 to form an ionization region 151. The first discharge electrode 200 and the second discharge electrode 300 are arranged in the ionization region 151.

[0106] The partition 140 is a partition plate, which is vertically set inside the housing 100. When the first discharge electrode 200 and the second discharge electrode 300 ionize, they ionize in the ionization region 151. By dividing the housing 100 into separate ionization regions 151, the independence of the ionization working space of the first discharge electrode 200 and the second discharge electrode 300 can be guaranteed, thus ensuring the ionization effect.

[0107] An electronic control region 152 is formed inside the housing 100, which is arranged side by side with the ionization region 151. An extension channel 160 is provided in the electronic control region 152 at a position corresponding to the slide 110, which can be used to accommodate the electrode substrate 600.

[0108] The electrical control area 152 is mainly used to arrange electrical control components and components such as the electrode power supply unit 400 that supplies power to the first discharge electrode 200 and the second discharge electrode 300.

[0109] The extension channel 160 is arranged in a corresponding position to the slide 110 and is connected to the slide 110. A through hole is provided on the partition 140.

[0110] When the movable second discharge electrode 300 moves away from the first discharge electrode 200 to increase the discharge distance D between the first discharge electrode 200 and the second discharge electrode 300, the end of the electrode substrate 600 will extend into the extension channel 160. The extension channel 160 can maximize the adjustment range of the distance D between the two electrodes within the limited volume of the air purifier, thereby more effectively controlling the electric field strength and generating different types of ions to purify the air.

[0111] The above embodiments have the following advantages and effects: The interior of the housing 100 is divided by the partition 140, so that the interior of the housing 100 is divided into a separately arranged ionization region 151 and an electronic control region 152. The ionization region 151 accommodates the first discharge electrode 200 and the second discharge electrode 300 used for ionization, ensuring that the first discharge electrode 200 and the second discharge electrode 300 do not interfere with the electronic control components in the electronic control region 152 when they are ionized, thus ensuring the normal operation of the entire air purification device.

[0112] In some embodiments of this application, reference is made to Figures 1-2 As shown, the housing 100 includes: Bottom shell 170; The cover 180 is connected to the bottom shell 170. When the cover 180 and the bottom shell 170 are connected and fixed, they can be fixed by snap-fit.

[0113] A moving channel 181 is provided on the cover 180 to facilitate the extension of the first discharge electrode 200 and the movement of the second discharge electrode 300. The moving channel 181 is elongated and provides space for the extension of the first discharge electrode 200 and for the movement of the second discharge electrode 300.

[0114] In some embodiments of this application, an air purification device is proposed, comprising: Casing 100; The first discharge electrode 200 is disposed inside the housing 100; The second discharge electrode 300 is disposed inside the housing 100 and is disposed opposite to the first discharge electrode 200. The electrode power supply unit 400 is used to supply a first voltage and a second voltage to the first discharge electrode 200 and the second discharge electrode 300 respectively, and there is a voltage difference between the first voltage and the second voltage; The spacing adjustment device 500 is used to drive the first discharge electrode 200 and the second discharge electrode 300 to move in order to adjust the spacing between the first discharge electrode 200 and the second discharge electrode 300.

[0115] In the arrangement, the first discharge electrode 200 is movably disposed within the housing 100, and the second discharge electrode 300 is fixedly disposed within the housing 100. The spacing adjustment device 500 is connected to the first discharge electrode 200 and drives the first discharge electrode 200 to move to change the spacing between the first discharge electrode 200 and the second discharge electrode 300.

[0116] Alternatively, the first discharge electrode 200 is fixedly disposed inside the housing 100, and the second discharge electrode 300 is movably disposed inside the housing 100. The spacing adjustment device 500 is connected to the second discharge electrode 300 to drive the second discharge electrode 300 to move. Alternatively, the first discharge electrode 200 may be movably disposed within the housing 100, and the second discharge electrode 300 may be movably disposed within the housing 100. The spacing adjustment device 500 includes a first spacing adjustment mechanism and a second spacing adjustment mechanism. The first spacing adjustment mechanism is connected to the first discharge electrode 200, and the second spacing adjustment mechanism is connected to the second discharge electrode 300.

[0117] Either the action of the first spacing adjustment mechanism or the second spacing adjustment mechanism can drive the first discharge electrode 200 or the second discharge electrode 300 to move, or the two mechanisms can act simultaneously to drive the two electrodes to move synchronously to adjust the spacing.

[0118] The first spacing adjustment mechanism and the second spacing adjustment mechanism may adopt the same structure as the spacing adjustment device 500 in the above embodiment.

[0119] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
