[0052] Hereinafter, exemplary embodiments of the present application will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application can be more thoroughly understood and the scope of the present application can be completely conveyed to those skilled in the art.

[0053] As shown Figures 1 to 5 in FIG. 1, a dust collecting plate electrode 110 according to a first aspect of an embodiment of the present application includes: a first insulating layer 111 formed with at least two notches 1111; a first conductive layer 112 formed with an operating side 1121, the first insulating layer 111 wrapping the first conductive layer 112, and the notches 1111 being arranged corresponding to the operating side 1121 so that a part of the operating side 1121 is exposed through the notches 1111.

[0054] The dust collecting plate electrode 110 provided by the embodiment of the present application includes a first insulating layer 111 and a first conductive layer 112. Among them, the first insulating layer 111 wraps the first conductive layer 112, so that the first insulating layer 111 can provide structural protection for the first conductive layer 112 and improve the safety of the dust collecting plate electrode 110 during use. In practical applications, the dust collecting plate electrode 110 provided by the embodiment of the present application can be used as a component of the dust collecting device 100. The dust collecting plate electrode 110 can be powered on through the first conductive layer 112, so as to have a certain voltage, which is convenient for forming an electric field of a certain strength between the dust collecting plate electrode 110 and other electrodes of the dust collecting device 100. When the gas to be purified flows through the electric field, the particulate matter carried by the gas to be purified can move towards the dust collecting plate electrode 110 under the action of the electric field and be adsorbed by the dust collecting plate electrode 110, thereby realizing the dust removal and purification of the gas to be purified.

[0055] Taking the case where the dust collecting plate electrode 110 is used as a component of the dust collecting device 100 in practical applications as an example, as Figure 5 shown in FIG. 2, the dust collecting plate electrode 110 can be connected to the first output terminal of the power supply unit 140 of the dust collecting device 100. The dust collecting device 100 may further include a repelling plate electrode 120. The repelling plate electrode 120 is arranged at an interval from the dust collecting plate electrode 110 and is connected to the second output terminal of the power supply unit 140. The voltage of the first output terminal is less than the voltage of the second output terminal, so that a certain potential difference can be formed between the dust collecting plate electrode 110 and the repelling plate electrode 120. At least a part of the operating side 1121 of the first conductive layer 112 can be arranged facing the repelling plate electrode 120, so that an electric field of a certain strength can be formed between the repelling plate electrode 120 and the dust collecting plate electrode 110, which is convenient for dust removal treatment of the gas to be purified. And based on the setting of the first insulating layer 111, it can provide structural protection for the first conductive layer 112, reduce the possibility of damage to the first conductive layer 112, and improve the safety of the dust collecting plate electrode 110 during use.

[0056] Moreover, the first insulating layer 111 is formed with notches 1111, and the number of the notches 1111 is at least two. The notches 1111 are arranged corresponding to the working side 1121 of the first conductive layer 112, so that a part of the first conductive layer 112 can be exposed to the external environment through the notches 1111. Thus, during use, the charges accumulated by the first conductive layer 112 with the increase of the operating time can be released through the notches 1111, avoiding the accumulation of a large amount of charges on the dust collecting plate 110, preventing the dust collecting plate 110 from repelling the particulate matters in the gas to be purified, creating favorable conditions for the particulate matters to approach and adhere to the dust collecting plate 110, thereby improving the dust removal efficiency of the dust collecting plate 110, being beneficial to enhancing the overall purification efficiency of the dust collecting device 100, and improving the user experience of the product.

[0057] Meanwhile, since the number of the notches 1111 is at least two, different parts of the working side 1121 of the first conductive layer 112 can be exposed, which on the one hand is beneficial to ensuring the charge release effect of the first conductive layer 112, reducing the possibility of a large amount of charges accumulating on the dust collecting plate 110, and providing further guarantee for improving the dust collection efficiency of the dust collecting plate 110. On the other hand, it can also avoid continuously and widely exposing the first conductive layer 112, being beneficial to reducing the possibility of damage to the first conductive layer 112 and prolonging the service life of the dust collecting plate 110. It can be understood that the dust collecting plate 110 needs to be cleaned after being used for a certain period of time. If the first conductive layer 112 is continuously and widely exposed, it is easy to cause damage to the first conductive layer 112 during the cleaning process. Therefore, based on the above settings, it is beneficial to reduce the possibility of damage to the first conductive layer 112 during the cleaning process and reduce the cleaning difficulty of the dust collecting plate 110.

[0058] It can be understood that the number of the notches 1111 can be equal to or more than two, such as three, four, five, etc., and no more limitations are made here.

[0059] It can be understood that the working side 1121 can include at least one side surface of the first conductive layer 112. In practical applications, at least part of the working side 1121 can be arranged facing the repelling plate 120 of the dust collecting device 100, so as to facilitate the formation of an electric field between the dust collecting plate 110 and the repelling plate 120; as Figure 2 shown, taking the first conductive layer 112 as a sheet structure as an example, the working side 1121 can be the surface of the sheet structure perpendicular to its thickness direction, so as to ensure that the working side 1121 has a large area, being beneficial to expanding the electric field space formed in practical applications.

[0060] It can be understood that the number of the working sides 1121 can also be more than one, and the specific number can be set in combination with the structural form of the first conductive layer 112 and the usage requirements, and no excessive limitation is made here. Taking the case where the first conductive layer 112 is a sheet structure as an example, the aforementioned working sides 1121 can be two mutually facing surfaces of the sheet structure perpendicular to its own thickness direction. Correspondingly, in practical applications, the repelling plates 120 can be arranged corresponding to the two working sides 1121 respectively, which is beneficial to expanding the distribution range of the electric field.

[0061] It can be understood that there can be various structural forms of the first conductive layer 112, and the specific structural form can be set in combination with the form of the corresponding repelling plate 120 and the usage requirements in practical applications, and no excessive limitation is made here. Exemplarily, as Figure 2 shown, in the case where the repelling plate 120 is a flat plate structure, the first conductive layer 112 and the dust collecting plate 110 as a whole can also be a relatively flat sheet structure, so that the working side 1121 can also be a relatively flat surface, which is convenient for the dust collecting plate 110 and the repelling plate 120 to cooperate to form a stable electric field; or it can also be as Figure 5 shown, in the case where the repelling plate 120 is distributed in a square spiral shape, the first conductive layer 112 and the dust collecting plate 110 as a whole can also be a sheet structure distributed in a square spiral shape. Thus, when the overall length of the dust collecting plate 110 and the repelling plate 120 is certain, the corresponding range between the dust collecting plate 110 and the repelling plate 120 can be increased, which is beneficial to expanding the electric field space. It can be understood that when the dust collecting plate 110 and the repelling plate 120 both distributed in a square spiral shape are arranged correspondingly, they can be distributed in a multi-layer square spiral shape as a whole, so that at least part of the dust collecting plate 110 can correspond to the repelling plate 120 on both sides in the thickness direction, thereby realizing the expansion of the electric field space and being beneficial to improving the dust collecting area and dust collecting efficiency of the dust collecting plate 110.

[0062] It can be understood that the first conductive layer 112 can be made of a conductive material to ensure the conductive performance of the first conductive layer 112, and then it is convenient for electrostatic dust collection; Exemplarily, the first conductive layer 112 can be made of materials such as metal materials, conductive plastics, or carbon-based conductive materials. Taking the case where the first conductive layer 112 is a sheet structure as an example, the first conductive layer 112 can be a sheet or a coating made of a conductive material, such as a metal sheet, a conductive plastic sheet, or a carbon-based conductive coating.

[0063] As Figure 2As shown, in some feasible examples, the first insulating layer 111 may include a first insulating portion 1112 and a second insulating portion 1113. The first conductive layer 112 may be disposed between the first insulating portion 1112 and the second insulating portion 1113, and the first conductive layer 112 may be connected to the first insulating portion 1112 and the second insulating portion 1113 by bonding. The first insulating portion 1112 may be provided with the aforementioned notch 1111. The aforementioned working side 1121 at least includes the side of the first conductive layer 112 facing the first insulating portion 1112, so that a part of the working side 1121 is exposed through the aforementioned notch 1111. It can be understood that the aforementioned working side 1121 may also include the side of the first conductive layer 112 facing the second insulating portion 1113. Correspondingly, the second insulating portion 1113 may also be provided with the aforementioned notch 1111, so as to cooperate with the notch 1111 provided in the first insulating portion 1112, further facilitating the multi-directional charge release of the first conductive layer 112, being beneficial to improving the charge release effect of the dust collecting plate 110, and providing further guarantee for the improvement of the dust collecting efficiency of the dust collecting plate 110.

[0064] As Figure 3 shown, in some examples, the first conductive layer 112 is a sheet-like structure, and a gap is formed between the aforementioned notch 1111 and the outer edge of the first conductive layer 112.

[0065] In this technical solution, the first conductive layer 112 may be set as a sheet-like structure. Correspondingly, the aforementioned working side 1121 may include at least one surface of the first conductive layer 112 in a direction perpendicular to its own thickness direction. Thus, while the first conductive layer 112 has a relatively large working side 1121 in area, it has a relatively small volume, which is conducive to saving the material usage of the first conductive layer 112, reducing the overall weight and manufacturing cost of the dust collecting plate 110. At the same time, a gap may be formed between the aforementioned notch 1111 and the outer edge of the first conductive layer 112. Thus, on the one hand, the relative positional relationship between the aforementioned notch 1111 and the first conductive layer 112 can be restricted, making the notch 1111 relatively close to the middle region of the first conductive layer 112, being beneficial to the charge accumulated at different positions of the first conductive layer 112 to be released through the notch 1111, improving the charge release effect of the dust collecting plate 110. On the other hand, it can also reduce the opening area of the notch 1111 to a certain extent, thus avoiding continuously and widely exposing the working side 1121 of the first conductive layer 112, being beneficial to ensuring the protection effect of the first insulating layer 111 on the first conductive layer 112 and prolonging the service life of the first conductive layer 112.

[0066] It can be understood that, as Figure 2As shown, when the first conductive layer 112 is in a sheet structure, the aforementioned working side 1121 may include at least one surface of the sheet structure perpendicular to its own thickness direction; correspondingly, the outer edge of the first conductive layer 112 is also the edge of the aforementioned working side 1121, such as Figure 3 shown, Figure 3 The dashed line in is used to schematically represent the outer edge of the first conductive layer 112. The formation of a gap between the aforementioned notch 1111 and the outer edge of the first conductive layer 112 means that the notch 1111 has a spacing distance from the edge of the working side 1121 in any direction parallel to the aforementioned working side 1121. Exemplarily, as Figure 3 shown, when the first conductive layer 112 is in a rectangular sheet structure, the aforementioned working side 1121 may include at least one surface of the rectangular sheet structure perpendicular to its own thickness direction, that is, a rectangular surface. Correspondingly, the four sides of the rectangular surface are the outer edges of the first conductive layer 112, and a certain spacing distance is formed between the notch 1111 and the outer edges of the first conductive layer 112 in each direction parallel to the aforementioned rectangular surface.

[0067] In some examples, the distance from the notch 1111 to the outer edge of the first conductive layer 112 is greater than or equal to 1 mm.

[0068] In this technical solution, the distance from the notch 1111 to the outer edge of the first conductive layer 112 can be set to be greater than or equal to 1 mm, so as to restrict the gap amount between the notch 1111 and the outer edge of the first conductive layer 112. Furthermore, on the one hand, the relative positional relationship between the notch 1111 and the first conductive layer 112 can be restricted, so that the notch 1111 is relatively close to the middle region of the first conductive layer 112, which is beneficial to the release of charges accumulated at different positions of the first conductive layer 112 through the notch 1111, and improves the charge release effect of the dust collecting plate 110; on the other hand, it can ensure that the first insulating layer 111 wraps the outer edge of the first conductive layer 112, ensure the protective effect of the first insulating layer 111 on the first conductive layer 112, and to a certain extent reduce the opening area of the notch 1111, avoid continuously and widely exposing the working side 1121 of the first conductive layer 112, and extend the service life of the first conductive layer 112.

[0069] In some examples, the first insulating layer 111 is made of a plastic material.

[0070] In this technical solution, the first insulating layer 111 can be made of a plastic material. It can be understood that most plastic materials have a relatively high resistivity, which can ensure the insulating effect of the first insulating layer 111, thereby improving the safety of the dust collecting plate 110 during use, facilitating the improvement of the user experience of the product, and enabling the first insulating layer 111 to have good strength and toughness, enhancing the protection effect of the first insulating layer 111 on the first conductive layer 112, extending the service life of the first conductive layer 112, and further reducing the maintenance cost of the dust collecting plate 110 during use.

[0071] In some feasible examples, the first insulating layer 111 can be a plastic substrate or an insulating plastic sleeve wrapped around the first conductive layer 112.

[0072] In some feasible examples, the first insulating layer 111 can be made of PET (Polyethylene glycol Terephthalate) or PP (Polypropylene).

[0073] In some examples, the surface resistivity of the first insulating layer 111 is greater than or equal to 10 11 Ω; and / or the thickness of the first insulating layer 111 is greater than or equal to 0.01 mm and less than or equal to 2 mm; and / or the surface resistivity of the first conductive layer 112 is less than or equal to 10 6 Ω; and / or the thickness of the first conductive layer 112 is greater than or equal to 0.01 mm and less than or equal to 2 mm.

[0074] In this technical solution, the surface resistivity of the first insulating layer 111 can be set to be greater than or equal to 10 11 Ω, so as to ensure that the first insulating layer 111 has strong insulating properties, and further provide guarantee for the safe use of the dust collecting plate 110.

[0075] In this technical solution, the thickness of the first insulating layer 111 can be set to be greater than or equal to 0.01 mm and less than or equal to 2 mm. On the one hand, this can avoid the thickness of the first insulating layer 111 being too thin, reduce the possibility of the first insulating layer 111 being broken down during use, avoid the dust collecting plate 110 from arcing, and be conducive to improving the use stability and safety of the dust collecting plate 110. On the other hand, it can also avoid the thickness of the first insulating layer 111 being too large, which is beneficial to saving the material usage for making the first insulating layer 111, and then reducing the manufacturing cost of the dust collecting plate 110.

[0076] In this technical solution, the surface resistivity of the first conductive layer 112 can be set to be less than or equal to 10 6Ω, so that on the one hand, the cost of the first conductive layer 112 can be saved while ensuring the conductive performance of the first conductive layer 112; on the other hand, it can also avoid the resistance of the first conductive layer 112 being too large, reduce the voltage attenuation of the first conductive layer 112, and ensure the voltage stability of the first conductive layer 112 during operation, thereby providing further protection for the dust collection performance of the dust collecting plate 110.

[0077] In this technical solution, the thickness of the first conductive layer 112 can be set to be greater than or equal to 0.01 mm and less than or equal to 2 mm. On the one hand, this can prevent the first conductive layer 112 from being too thin, thereby improving the structural reliability of the first conductive layer 112, reducing the probability of damage to the first conductive layer 112, and helping to reduce the difficulty of cleaning the first conductive layer 112; on the other hand, it can also prevent the first conductive layer 112 from being too thick, thereby preventing the resistance of the first conductive layer 112 from being too large, which is beneficial to preventing the voltage of the first conductive layer 112 from attenuating, improving the voltage stability of the dust collecting plate 110, and further ensuring the dust collecting performance of the dust collecting plate 110.

[0078] It can be understood that the above four parameter ranges provided in the technical solution can be adopted at the same time, or any one, any two, or any three of them can be adopted.

[0079] In some feasible examples, the thickness of the first insulating layer 111 may be equal to 0.15 mm; and / or the thickness of the first conductive layer 112 may be equal to 0.5 mm.

[0080] In some examples, a ratio of an area of ​​the exposed portion of the working side 1121 to an area of ​​the working side 1121 is greater than or equal to 1% and less than or equal to 50%.

[0081] In this technical solution, the area ratio of the exposed portion of the working side 1121 is constrained, and the ratio of the area of ​​the exposed portion of the working side 1121 to the area of ​​the working side 1121 can be set to be greater than or equal to 1% and less than or equal to 50%. On the one hand, it can avoid exposing the first conductive layer 112 in a large range, thereby reducing the probability of damage to the first conductive layer 112, and can ensure the coverage effect of the first insulating layer 111 and the safety of the dust collecting plate 110. At the same time, it can also avoid the excessive release of charge, which is beneficial to ensure the dust collection efficiency; on the other hand, On the one hand, since the number of notches 1111 is at least two, the area of ​​the exposed portion of the working side 1121 is the sum of the cross-sectional areas of each notch 1111. Based on the above-mentioned setting, the area of ​​the exposed portion of the working side 1121 corresponding to a single notch 1111 can be smaller, thereby further reducing the continuously exposed area of ​​the working side 1121, which is beneficial to further reduce the probability of damage to the first conductive layer 112, and also helps to improve the uniformity of charge release at various locations of the dust collecting plate 110, thereby improving the dust collection uniformity of the dust collecting plate 110.

[0082] In some feasible examples, the ratio of the area of the exposed part of the working side 1121 to the area of the working side 1121 is greater than or equal to 10% and less than or equal to 40%, so that the protection effect of the first conductive layer 112 and the dust collection effect of the dust collection plate 110 can be further balanced.

[0083] In some examples, the cross-sectional area of the aforementioned notch 1111 is greater than or equal to 1 mm 2 .

[0084] In this technical solution, the cross-sectional area of the aforementioned notch 1111 can be set to be greater than or equal to 1 mm 2 , so as to avoid the cross-sectional area of a single notch 1111 being too small, reduce the possibility of electric sparks generated at the notch 1111, and further improve the use safety and reliability of the dust collection plate 110.

[0085] Exemplarily, as Figures 1 to 4 shown, when the cross-section of the aforementioned notch 1111 is rectangular, the length and width of the aforementioned rectangle can be set to be greater than 1 mm; when the aforementioned notch 1111 is circular, the diameter of the aforementioned notch 1111 can be set to be greater than 1 mm. Based on the setting of the aforementioned cross-sectional area, the cross-sectional dimension parameters of the notch 1111 can be further set in combination with the cross-sectional shape of the notch 1111, and no excessive limitation is made here.

[0086] As Figure 4 shown, in some examples, the dust collection plate 110 further includes: a first connection terminal 113, which is arranged at one end of the first conductive layer 112, and the first conductive layer 112 is used to be connected to a power supply device through the first connection terminal 113.

[0087] In this technical solution, the dust collection plate 110 may further include a first connection terminal 113 arranged at one end of the first conductive layer 112. In practical applications, the first conductive layer 112 can be connected to a power supply device through the aforementioned first connection terminal 113 to realize the power connection of the dust collection plate 110, and then facilitate the cooperation of the dust collection plate 110 with other plates of the dust collection device 100 to form an electric field with a certain intensity for electrostatic dust collection operations; and, based on the setting of the first connection terminal 113, there is no need to directly connect the first conductive layer 112 to the power supply device, which is beneficial to improving the connection convenience between the dust collection plate 110 and the power supply device and avoiding the probability of damage to the first conductive layer 112 during the electrical connection process.

[0088] In some examples, the length L of the first connection terminal 113 is greater than or equal to 1 mm and less than or equal to 10 mm; and / or the surface resistivity of the first conductive layer 112 is less than or equal to 10 3 Ω.

[0089] In this technical solution, the length L of the first terminal 113 can be set to be greater than or equal to 1 mm and less than or equal to 10 mm. On the one hand, this can avoid the length L of the first terminal 113 being too small, which is beneficial to ensuring the stability and convenience when the first terminal 113 is connected to the power supply device; on the other hand, it can also avoid the length L of the first terminal 113 being too large, which is beneficial to saving the manufacturing cost of the first terminal 113.

[0090] It can be understood that, as Figure 4 shown, the first terminal 113 is connected to one end of the first conductive layer 112, so the length L of the first terminal 113 is also the length that the first terminal 113 extends relative to the first conductive layer 112.

[0091] In this technical solution, the surface resistivity of the first terminal 113 can be set to be less than or equal to 10 3 Ω, so as to ensure that the first terminal 113 has strong electrical conductivity, reduce the power loss at the first terminal 113, and ensure the power connection effect and voltage reliability of the dust collecting plate 110.

[0092] It can be understood that the two parameter ranges provided in this technical solution can be adopted simultaneously, or any one of them can be adopted.

[0093] As Figures 1 to 4 shown, in some examples, at least two notches 1111 are spaced apart and formed in the first insulating layer 111.

[0094] In this technical solution, the aforementioned at least two notches 1111 are spaced apart and formed on the aforementioned first insulating layer 111. Based on the aforementioned setting, the positions of different notches 1111 can form a greater difference, which is convenient for exposing different parts of the first conductive layer 110. On the one hand, it can be beneficial to the release of charges of the first conductive layer 112 while further improving the uniformity of charge release, providing further guarantee for improving the dust collection efficiency of the dust collecting plate 110; on the other hand, it can also further avoid the continuous and large-scale exposure of the first conductive layer 112 by each notch 1111, which is beneficial to further reducing the possibility of damage to the first conductive layer 112 and extending the service life of the dust collecting plate 110.

[0095] As Figures 5 to 7As shown in the figure, according to the second aspect of the embodiments of the present application, a dust collection device 100 is provided, which includes: a power supply unit 140 including a first output terminal and a second output terminal, and the voltage of the first output terminal is less than that of the second output terminal; a repelling electrode plate 120 connected to the second output terminal; and a dust collection electrode plate 110 as proposed in any one of the above first aspects, connected to the first output terminal; wherein, the dust collection electrode plate 110 and the repelling electrode plate 120 are arranged at intervals, and at least part of the working side 1121 faces the repelling electrode plate 120.

[0096] The dust collection device 100 provided by the embodiments of the present application includes a power supply unit 140, a repelling electrode plate 120, and a dust collection electrode plate 110 as proposed in any one of the above first aspects. Among them, the power supply unit 140 is used to supply power to the dust collection electrode plate 110 and the repelling electrode plate 120. The dust collection electrode plate 110 and the repelling electrode plate 120 are respectively connected to the first output terminal and the second output terminal of the power supply unit 140, and the voltage of the first output terminal is lower than that of the second output terminal. Thus, the voltage of the dust collection electrode plate 110 is lower than that of the repelling electrode plate 120. The dust collection electrode plate 110 and the repelling electrode plate 120 are arranged at intervals, and at least part of the working side 1121 faces the repelling electrode plate 120. Therefore, an electric field with a certain intensity can be formed between the dust collection electrode plate 110 and the repelling electrode plate 120. When the gas to be purified flows through the aforementioned electric field, the particulate matter carried by the gas to be purified can move towards the dust collection electrode plate 110 under the action of the electric field and be adsorbed by the dust collection electrode plate 110, thereby realizing the dust removal and purification of the gas to be purified.

[0097] It can be understood that the structural forms of the dust collection electrode plate 110 and the repelling electrode plate 120 can be set according to actual needs. Exemplarily, both the dust collection electrode plate 110 and the repelling electrode plate 120 can be in a flat plate structure, and a high parallelism can be maintained between the dust collection electrode plate 110 and the repelling electrode plate 120 to form a stable electric field; or, as Figure 5 shown in the figure, both the dust collection electrode plate 110 and the repelling electrode plate 120 can be distributed in a square spiral shape, and there can be a certain proportional relationship between their structural dimensions. When the dust collection electrode plate 110 and the repelling electrode plate 120 are correspondingly arranged, they can form a multi-layer square spiral structure, so that at least part of the dust collection electrode plate 110 can correspond to the repelling electrode plate 120 on both sides in the thickness direction, thereby realizing the expansion of the electric field space and facilitating the improvement of the dust collection area and dust collection efficiency of the dust collection device 100.

[0098] As Figure 6 and Figure 7 shown in the figure, in some examples, the repelling electrode plate 120 includes: a second conductive layer 122; a second wiring terminal 123 provided at one end of the second conductive layer 122, and the second conductive layer 122 is connected to the second output terminal through the second wiring terminal 123; and a second insulating layer 121 wrapping the second conductive layer 122.

[0099] In this technical solution, the repelling electrode plate 120 may include a second insulating layer 121, a second conductive layer 122, and a second terminal 123. Among them, the second terminal 123 may be provided at one end of the second conductive layer 122, and the second conductive layer 122 may be connected to the second output terminal of the aforementioned power supply unit 140 through the second terminal 123, so as to facilitate the connection of the repelling electrode plate 120 to electricity, and then cooperate with the dust collecting electrode plate 110 to form an electric field. The second insulating layer 121 wraps the aforementioned second conductive layer 122 to provide structural protection for the second conductive layer 122, reduce the possibility of damage to the second conductive layer 122, extend the service life of the repelling electrode plate 120, save the maintenance cost of the dust collecting device 100, and improve the operation safety and reliability of the repelling electrode plate 120, which is beneficial to improving the user experience of the product.

[0100] It should be noted that Figure 7 the second terminal 123 is hidden.

[0101] It can be understood that the structure of the repelling electrode plate 120 has a high similarity to the structure of the dust collecting electrode plate 110. In practical applications, some parameter specifications of the repelling electrode plate 120 can be the same as those of the dust collecting electrode plate 110.

[0102] Exemplarily, as Figure 7 shown, the second insulating layer 121 may include a third insulating portion 1211 and a fourth insulating portion 1212. The second conductive layer 122 may be disposed between the third insulating portion 1211 and the fourth insulating portion 1212, and the second conductive layer 122 may be connected to the third insulating portion 1211 and the fourth insulating portion 1212 by an adhesive method. It can be understood that the second conductive layer 122 may be a sheet structure, and a wiring port may be formed at one end of the second insulating portion 1113 corresponding to the second conductive layer 122 to facilitate the connection of the second conductive layer 122 to the second terminal 123.

[0103] Exemplarily, the second insulating layer 121 may be made of a plastic material. For example, it may be made of PET or PP. The second insulating layer 121 may be a plastic substrate or an insulating plastic sleeve that wraps the second conductive layer 122.

[0104] Exemplarily, the surface resistivity of the second insulating layer 121 is greater than or equal to 10 11 Ω; and / or the thickness of the second insulating layer 121 is greater than or equal to 0.01 mm and less than or equal to 2 mm; and / or the surface resistivity of the second conductive layer 122 is less than or equal to 10 6 Ω; and / or the thickness of the second conductive layer 122 is greater than or equal to 0.01 mm and less than or equal to 2 mm.

[0105] Exemplarily, the length of the second terminal 123 is greater than or equal to 1 mm and less than or equal to 10 mm; and / or the surface resistivity of the second conductive layer 122 is less than or equal to 10 3 Ω.

[0106] As Figure 5 shown, in some examples, the distance W between the dust collecting plate 110 and the repelling plate 120 is greater than or equal to 2 mm and less than or equal to 20 mm.

[0107] In this technical solution, the distance W between the dust collecting plate 110 and the repelling plate 120 can be greater than or equal to 2 mm and less than or equal to 20 mm. Thus, on the one hand, it can avoid the distance between the dust collecting plate 110 and the repelling plate 120 from being too small, facilitating the formation of a relatively large electric field space between the dust collecting plate 110 and the repelling plate 120, and then improving the treatment efficiency of the dust collecting device 100 for the gas to be purified; on the other hand, it can also avoid the distance between the dust collecting plate 110 and the repelling plate 120 from being too large, being able to shorten the distance between the particulate matter in the electric field space and the dust collecting plate 110, and then facilitating the movement of small-scale particulate matter towards the dust collecting plate 110 and improving the dust collecting performance of the dust collecting device 100.

[0108] As Figure 5 shown, in some examples, the dust collecting device 100 further includes: an auxiliary plate 130, disposed between the dust collecting plate 110 and the repelling plate 120, with a gap formed between one side of the auxiliary plate 130 and the dust collecting plate 110, and a gap formed between the other side and the repelling plate 120.

[0109] In this technical solution, the dust collecting device 100 can further include an auxiliary plate 130. The auxiliary plate 130 can be arranged between the dust collecting plate 110 and the repelling plate 120, and gaps are respectively formed between both sides of the auxiliary plate 130 and the dust collecting plate 110 and the repelling plate 120. Thus, the auxiliary plate 130 can be in the electric field between the dust collecting plate 110 and the repelling plate 120 and further divide the aforementioned electric field to define more gas channels. Then, when the gas to be purified flows through the electric field between the auxiliary plate 130 and the repelling plate 120, the particulate matter carried by the gas to be purified can approach the auxiliary plate 130 and be adsorbed and collected by the auxiliary plate 130. When the gas to be purified flows through the electric field between the auxiliary plate 130 and the dust collecting plate 110, the particulate matter carried by the gas to be purified can approach the dust collecting plate 110 and be adsorbed and collected by the dust collecting plate 110. Thereby, it can further increase the dust collecting area of the dust collecting device 100, and when the distance between the dust collecting plate 110 and the repelling plate 120 is fixed, the setting of the auxiliary plate 130 can further reduce the distance between adjacent plates, and then shorten the distance between the particulate matter and the plates, improving the dust collecting efficiency of the dust collecting device 100.

[0110] In some feasible examples, the auxiliary electrode plate 130 can be made of an insulating material, such as insulating plastic materials like PET or PP.

[0111] As Figure 5 shown, in some examples, the ratio of the distance W1 from the auxiliary electrode plate 130 to the dust collecting electrode plate 110 to the distance W2 from the auxiliary electrode plate 130 to the repelling electrode plate 120 is greater than or equal to 0.8 and less than or equal to 1.3.

[0112] In this technical solution, the distance W1 from the auxiliary electrode plate 130 to the dust collecting electrode plate 110 and the distance W2 between the auxiliary electrode plate 130 and the repelling electrode plate 120 are constrained. Based on the foregoing settings, it is possible to make the auxiliary electrode plate 130 in the middle region of the electric field between the dust collecting electrode plate 110 and the repelling electrode plate 120, avoiding the auxiliary electrode plate 130 being too close to the dust collecting electrode plate 110 or the repelling electrode plate 120, so as to facilitate making the gas flow rate between the auxiliary electrode plate 130 and the dust collecting electrode plate 110 close to the gas flow rate between the auxiliary electrode plate 130 and the repelling electrode plate 120, and then balancing the dust collection efficiency on both sides of the auxiliary electrode plate 130, avoiding a significant reduction in the dust collection efficiency on one side of the auxiliary electrode plate 130, and providing a reliable guarantee for improving the overall dust collection efficiency of the dust collection device 100.

[0113] Exemplarily, when the distance W between the dust collecting electrode plate 110 and the repelling electrode plate 120 is 20 mm, the distance W1 from the auxiliary electrode plate 130 to the dust collecting electrode plate 110 can be greater than or equal to 9 mm and less than or equal to 11 mm. Correspondingly, the distance W2 from the auxiliary electrode plate 130 to the repelling electrode plate 120 can be less than or equal to 11 mm and greater than or equal to 9 mm. It can be understood that the foregoing W, W1, and W2 are measured based on the median line of the thickness of each electrode plate.
