DETAILED DESCRIPTION

[0030] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0031] like Figure 2-Figure 9As shown, an embodiment of the present application provides an air purification device 100, including a dust collecting module 1, the dust collecting module 1 includes a plurality of first conductive electrode plates 11, a plurality of second conductive electrode plates 12 and a plurality of auxiliary insulating plates 13, the first conductive electrode plates 11 and the second conductive electrode plates 12 are alternately arranged, an auxiliary insulating plate 13 is arranged between each adjacent first conductive electrode plate 11 and second conductive electrode plate 12, and the dust collecting module 1 is an integrated structure of injection molding.

[0032] In the dust collecting module 1 of the air purification device 100, the first conductive electrode plate 11 and the second conductive electrode plate 12 are alternately arranged in sequence, and an auxiliary insulating plate 13 is provided between any adjacent first conductive electrode plates 11 and second conductive electrode plates 12, and there is a ventilation gap between the auxiliary insulating plate 13 and the adjacent first conductive electrode plates 11, and between the auxiliary insulating plate 13 and the adjacent second conductive electrode plates 12, for air to pass through ( Fig. 9 In the figure, the horizontal arrow W indicates the flow direction of air).

[0033] The dust collecting module 1 can be powered by the power supply module 5, and the first conductive electrode plate 11 and the second conductive electrode plate 12 can be electrically connected to the two poles of the power supply module 5 (e.g., the first conductive electrode plate 11 can be electrically connected to the negative high voltage pole of the power supply module 5, and the second conductive electrode plate 12 can be electrically connected to the grounding pole of the power supply module 5 (e.g., the voltage of the first conductive electrode plate 11 can be -8KV, and the voltage of the second conductive electrode plate 12 can be 0KV)) to form an electric field between the first conductive electrode plate 11 and the adjacent second conductive electrode plate 12 ( Fig. 9 In the figure, the vertical arrow E indicates the direction of the electric field).

[0034] like Fig. 9 As shown, when air passes through the ventilation gap of the dust collecting module 1, the charged particles in the air can move under the action of the electric field, such as: the movement direction of the negatively charged particles under the action of the electric field can be opposite to the direction of the electric field. Therefore, in the dust collecting module 1, the first conductive electrode plate 11 does not collect dust, and the upper surface of the first auxiliary insulating plate 13, the lower surface of the second auxiliary insulating plate 13, and the upper surface of the third auxiliary insulating plate 13 from top to bottom can collect dust, and the upper and lower plate surfaces of the second conductive electrode plate 12 can both collect dust (that is, the auxiliary insulating plate 13 collects dust on one side, and the second conductive electrode plate 12 collects dust on both sides). The dust collecting module 1 can be used to electrostatically remove dust from the air to achieve air purification.

[0035] The dust collecting module 1 is injection molded, wherein the first conductive electrode plate 11 and the second conductive electrode plate 12 can be injection molded with conductive plastic masterbatch, and the auxiliary insulating plate 13 can be injection molded with insulating plastic masterbatch. The dust collecting module 1 is an integrated structure of injection molding as a whole, which can reduce the labor cost of assembly and save a lot of material costs. In addition, compared with the original IFD (Intense Field Dielectric) mode processing (mainly including the steps of screen printing ink on the surface of the PP (polypropylene) Wantong board, then stacking and hot-cutting and sealing, and finally connecting the wires and encapsulating the frame), the processing procedure is complicated, the labor cost is high, and the manufacturing shape is limited. The dust collecting module 1 that is integrally molded by injection molding is not limited in its manufacturing shape, and integrated modules of different shapes can be processed to meet the use requirements of different products.

[0036] Therefore, the dust collecting module 1 of the embodiment of the present application is injection molded, which has a simple process and low cost; the shape of the dust collecting module 1 can be customized and can match different products with a high degree of matching; the dust collecting module 1 is an integrated structure of injection molding and does not need to be fixed with glue, etc., so the dust collecting module 1 has no odor; the dust collecting module 1 is disassembled and washable, and does not need to be replaced frequently, thereby reducing the cost of use; the cumulative purification amount of the dust collecting module 1 meets the latest national standards.

[0037] In some exemplary embodiments, Figure 6-Figure 9 As shown, the dust collecting module 1 further includes insulating ribs 14 , and the insulating ribs 14 are connected between adjacent auxiliary insulating plates 13 .

[0038] Adding insulating ribs 14 between adjacent auxiliary insulating plates 13 can increase the creepage distance between adjacent first conductive electrode plates 11 and second conductive electrode plates 12 to prevent sparking between adjacent first conductive electrode plates 11 and second conductive electrode plates 12 .

[0039] Of course, when the distance between the adjacent first conductive electrode plates 11 and the second conductive electrode plates 12 is large enough (eg, the distance reaches 20-30 mm), there is sufficient creepage distance between the adjacent first conductive electrode plates 11 and the second conductive electrode plates 12, and therefore, the insulating ribs 14 may not be provided.

[0040] In some exemplary embodiments, Figure 6-Figure 8 As shown, the insulating ribs 14 connected to the auxiliary insulating plate 13 on the side close to the first conductive electrode plate 11 are staggered with the insulating ribs 14 connected to the auxiliary insulating plate 13 on the side close to the second conductive electrode plate 12 .

[0041] The insulating ribs 14 connected to the auxiliary insulating plate 13 and respectively located on both sides of the auxiliary insulating plate 13 (the side close to the first conductive electrode plate 11 and the side close to the second conductive electrode plate 12) are staggered, which can further increase the creepage distance.

[0042] In some exemplary embodiments, Figure 6-Figure 9 As shown, the dust collecting module 1 also includes an insulating frame 15, the first conductive electrode plate 11, the second conductive electrode plate 12 and the auxiliary insulating plate 13 are all located in the insulating frame 15, and both ends of the auxiliary insulating plate 13 are connected to the insulating frame 15, and the first conductive electrode plate 11 and the second conductive electrode plate 12 are cross-arranged with the insulating ribs 14.

[0043] In the dust collecting module 1, the auxiliary insulating plate 13 may be located in the insulating frame 15, and both ends of the auxiliary insulating plate 13 are connected to the insulating frame 15, such as: the insulating frame 15 may be rectangular as a whole, and both ends of the auxiliary insulating plate 13 may be respectively connected to two oppositely arranged frame walls of the insulating frame 15. The first conductive electrode plate 11 and the second conductive electrode plate 12 are also located in the insulating frame 15, and the first conductive electrode plate 11 and the second conductive electrode plate 12 are both arranged crosswise with the insulating ribs 14, so that the first conductive electrode plate 11 and the second conductive electrode plate 12 are supported and fixed by the insulating ribs 14, so that the insulating frame 15, the first conductive electrode plate 11, the second conductive electrode plate 12, the auxiliary insulating plate 13 and the insulating ribs 14 can be connected into an integral structure.

[0044] In the dust collecting module 1 , the insulating ribs 14 can increase the creepage distance on the one hand, and can serve as a fixing frame for the first conductive electrode plate 11 and the second conductive electrode plate 12 on the other hand, to support and fix the first conductive electrode plate 11 and the second conductive electrode plate 12 .

[0045] In some exemplary embodiments, the insulating frame 15, insulating ribs 14 and auxiliary insulating plate 13 of the dust collection module 1 can be injection molded using the same insulating plastic masterbatch, and of course, different insulating plastic masterbatches can also be injection molded; the first conductive electrode plate 11 and the second conductive electrode plate 12 can be injection molded using the same conductive plastic masterbatch, and of course, different conductive plastic masterbatches can also be injection molded.

[0046] In some exemplary embodiments, the dust collection module 1 as a whole may be cylindrical or rectangular (such as square) or other shapes to meet the usage requirements of different products.

[0047] In some exemplary embodiments, Figure 2-Figure 5 As shown, the air purification device 100 also includes a charging module 2, and the charging module 2 is located on the air inlet side of the dust collecting module 1.

[0048] In the air purification device 100, the charging module 2 is located on the air inlet side of the dust collecting module 1, that is, along the air flow direction, the charging module 2 is located upstream of the dust collecting module 1. The charging module 2 can be powered by the power supply module 5. After the charging module 2 is powered on, the bacteria or dust particles in the air are charged by the action of high voltage electricity (ionization, instantaneous impact, oxidation), and the particles driven can be adsorbed on the dust collecting module 1. When the dust collecting module 1 is full of dust, the user can be reminded to clean the dust collecting module 1 regularly through an intelligent program (such as: APP / indicator light / display / voice, etc.), or the after-sales service can be reminded to clean the dust collecting module 1 regularly.

[0049] In some exemplary embodiments, Figure 2-Figure 5 and Fig.10 As shown, the charging module 2 includes a mounting bracket 21, a discharge portion 23 and a third conductive electrode plate 22, wherein the discharge portion 23 is mounted on the mounting bracket 21, and the third conductive electrode plate 22 is provided with a ventilation hole 221, and the discharge portion 23 extends into the ventilation hole 221. The discharge portion 23 may be a discharge tip, such as a discharge needle.

[0050] The charging module 2 adopts the form of a discharge part 23 + a third conductive electrode plate 22, and the discharge part 23 and the third conductive electrode plate 22 can be electrically connected to the two poles of the power supply module 5 respectively (for example, the discharge part 23 can be electrically connected to the negative high voltage pole of the power supply module 5, and the third conductive electrode plate 22 can be electrically connected to the grounding pole of the power supply module 5). After the charging module 2 is powered on, the discharge part 23 can discharge to charge (charge) particles such as bacteria and dust in the air; the dust collection module 1 can use high-voltage static electricity to form an electric field and adsorb charged particles, so that the particles in the air are adsorbed onto the dust collection module 1 to achieve the effect of purifying the air.

[0051] In the charging module 2 of the embodiment of the present application, the third conductive electrode plate 22 is provided with a ventilation hole 221, and the discharge part 23 can extend into the ventilation hole 221, so when the air passes through the ventilation hole 221 of the third conductive electrode plate 22, the discharge part 23 discharges to charge particles such as bacteria and dust in the air. Since the discharge part 23 extends into the ventilation hole 221 of the third conductive electrode plate 22, the overall thickness of the charging module 2 is reduced and the space occupied is reduced, which is conducive to reducing the overall size of the air purification device 100.

[0052] In some exemplary embodiments, Figure 2-Figure 3 and Fig.10 As shown, the mounting bracket 21 includes a mounting frame 211 and a mounting arm 212. The mounting arm 212 is located in the mounting frame 211, and the first end of the mounting arm 212 is connected to the mounting frame 211, and the second end extends toward the center of the ventilation hole 221. The discharge portion 23 is arranged at the second end of the mounting arm 212.

[0053] In the mounting bracket 21, a plurality of mounting arms 212 may be provided, and a plurality of ventilation holes 221 may also be provided on the third conductive electrode plate 22, and the plurality of mounting arms 212 correspond one-to-one to the plurality of ventilation holes 221. The first end of the mounting arm 212 is connected to the mounting frame 211, and the second end may extend toward the center of the corresponding ventilation hole 221, so that the discharge portion 23 provided at the second end of the mounting arm 212 is located at the center of the ventilation hole 221, so as to form a discharge between the discharge portion 23 and the side wall of the ventilation hole 221, so that particles such as bacteria and dust in the air are charged.

[0054] In some exemplary embodiments, Figure 2-Figure 4 As shown, the mounting frame 211 is located on a side of the third conductive electrode plate 22 close to the dust collecting module 1 , so that the discharge portion 23 arranged at the second end of the mounting arm 212 faces the air inlet side of the charging module 2 .

[0055] In some exemplary embodiments, the mounting frame 211 of the charging module 2 and the third conductive electrode plate 22 of the charging module 2 are fixedly connected to the dust collecting module 1. Among them, the mounting frame 211 and the third conductive electrode plate 22 of the charging module 2 and the insulating frame 15 of the dust collecting module 1 can be fixedly connected to fix the charging module 2 and the dust collecting module 1, and then the charging module 2 and the dust collecting module 1 can be removed at the same time for cleaning.

[0056] Of course, it is also possible to only disassemble and clean the dust collection module 1 without disassembling and cleaning the charging module 2.

[0057] In some exemplary embodiments, Figure 3 As shown, an electrical connection part 3 is provided on one side of the dust collection module 1 or the charging module 2, and both the dust collection module 1 and the charging module 2 are electrically connected to the electrical connection part 3, and the electrical connection part 3 is configured to be detachably connected to the power supply module 5.

[0058] The electrical connection part 3 can be arranged on the outer wall of the insulating frame 15 of the dust collecting module 1, or the electrical connection part 3 can also be arranged on the outer wall of the mounting frame 211 of the charging module 2 or the third conductive electrode plate 22. The dust collecting module 1 and the charging module 2 can be electrically connected to the power supply module 5 through the electrical connection part 3, so that the power supply module 5 can supply power to the dust collecting module 1 and the charging module 2.

[0059] In some exemplary embodiments, Figure 3 As shown, the electrical connection portion 3 includes two conductive springs, and the conductive springs are arranged to contact and conduct electricity with the power supply module 5 .

[0060] The electrical connection part 3 includes two conductive spring clips, one conductive spring clip can be electrically connected to the first conductive electrode plate 11 of the dust collecting module 1 and the discharge part 23 of the charging module 2, and the other conductive spring clip can be electrically connected to the second conductive electrode plate 12 of the dust collecting module 1 and the third conductive electrode plate 22 of the charging module 2; the two conductive spring clips can also respectively contact the two poles of the power supply module 5 to achieve electrical connection.

[0061] The conductive spring sheet is elastic to ensure that the conductive spring sheet can fully contact the two poles of the power supply module 5, so as to avoid the power supply module 5 being unable to supply power to the dust collection module 1 and the charging module 2 due to poor contact. In addition, the provision of the two conductive spring sheets makes it easy for the conductive spring sheet to contact or separate from the two poles of the power supply module 5, so that the dust collection module 1 and the charging module 2 can be disassembled for cleaning.

[0062] In some exemplary embodiments, Figure 3 As shown, a switch 4 is also provided on one side of the dust collecting module 1 or the charging module 2, and the switch 4 is configured to control the on-off of the electrical connection part 3 and the dust collecting module 1, and the on-off of the electrical connection part 3 and the charging module 2. The switch 4 may be a micro switch or other forms of switches.

[0063] The switch 4 can be set on a circuit in which a conductive spring is electrically connected to the first conductive electrode plate 11 of the dust collecting module 1 and the discharge part 23 of the charging module 2, so as to control the on and off of the conductive spring and the dust collecting module 1 and the charging module 2 through the switch 4. After the dust collecting module 1 and the charging module 2 are installed in place (at this time, the two conductive springs are in contact with the two poles of the power supply module 5 respectively for electrical conduction), the switch 4 can connect the conductive spring with the dust collecting module 1 and the charging module 2 to realize power supply; after the dust collecting module 1 and the charging module 2 are disassembled, the switch 4 can disconnect the conductive spring from the dust collecting module 1 and the charging module 2, thereby improving the safety of the air purification device 100.

[0066] In some exemplary embodiments, the air purification device 100 is detachably connected to the housing.

[0067] The air purifying device 100 is detachably connected to the housing so that after the air purifying device 100 has been working for a period of time, the air purifying device 100 can be disassembled and cleaned.
