[0149] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are only for illustrating the essential spirit of the technical solution of the present invention.

[0150] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0151] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "in an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0152] In the following description, in order to clearly demonstrate the structure and working method of the present invention, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0153] In one embodiment of the present invention, an adsorption unit is provided, the adsorption unit including a plurality of adsorption electrodes arranged at intervals; each adsorption electrode includes at least two adsorption sidewalls, two adjacent adsorption sidewalls are connected to each other and form a certain angle; an airflow channel is formed between two adjacent adsorption electrodes, the airflow channel being configured to allow airflow to flow along the airflow channel in a manner that changes direction at least once.

[0154] In another embodiment of the present invention, an adsorption unit is provided, the adsorption unit including a plurality of adsorption electrodes arranged at intervals, an airflow channel is formed between two adjacent adsorption electrodes, and the direction of airflow entering the airflow channel is different from the direction of the airflow channel.

[0155] It should be noted that the airflow channel has at least one bend, so that when the airflow passes through the airflow channel, the airflow changes direction at least once along the airflow channel, rather than the gas entering from the air inlet and flowing directly out from the air outlet.

[0156] It should also be noted that the aforementioned adsorption unit can serve as the adsorption unit for an electric field device. The electric field device discharges and ionizes the gas particles, causing them to combine with charged ions, thus acquiring an electrical charge. These charged particles then move towards and deposit within the adsorption unit. The design of this adsorption unit causes the gas to swirl within or just upon entering the unit, increasing the residence time and resulting in greater particle deposition, thereby improving dust removal efficiency. Furthermore, compared to airflow flowing in a channel without changing direction, configuring the airflow channel to change direction at least once increases the area of ​​the adsorption unit, further enhancing adsorption efficiency.

[0157] In another embodiment of the present invention, an electric field system is provided, the electric field system including an adsorption unit, a discharge unit and a dust removal unit; the adsorption unit and the discharge unit are used to form an electric field; the dust removal unit includes at least one scraper, the scraper being movably arranged on the surface of the adsorption unit to remove particulate matter adsorbed on the surface of the adsorption unit;

[0158] Alternatively, an electric field system is provided, the electric field system including an adsorption unit, a discharge unit and a dust removal unit; the adsorption unit and the discharge unit are used to form an electric field; the dust removal unit includes at least one scraper and a motor lifting mechanism, the motor lifting mechanism being configured to control the scraper to be movably arranged on the surface of the adsorption unit to remove particulate matter adsorbed on the surface of the adsorption unit.

[0159] It is worth noting again that the above-mentioned electric field system can remove particulate matter adsorbed on the surface of the adsorption unit by a simple push-pull action; or the scraper can be cleaned by a motor, making the scraper movement speed controllable and more uniform, ultimately resulting in a cleaner self-cleaning of the electric field and extending the service life of the electric field.

[0160] Finally, the particulate matter mentioned above includes, but is not limited to, solid particles, droplets, solid particles with attached liquid, aerosols, plasma-state solid particles or droplets, and may also be microorganisms such as bacteria and fungi.

[0161] Example 1

[0162] Figure 1 This is a cross-sectional schematic diagram of a V-shaped adsorption unit according to an embodiment of the present invention. The adsorption unit 10 includes a plurality of adsorption electrodes 100 arranged at intervals. Each adsorption electrode 100 includes at least two adsorption sidewalls 130. Two adjacent adsorption sidewalls 130 are connected to each other and form a certain angle. An airflow channel 110 is formed between two adjacent adsorption electrodes 100. The airflow channel 110 is configured to allow the airflow to flow along the airflow channel 110 in a manner that changes direction at least once.

[0163] With this design, the cross-section of the airflow channel 110 has at least one bend, so that when the airflow passes through the airflow channel 110, the airflow changes direction at least once along the airflow channel 110, instead of the gas entering from the inlet 121 and flowing directly out from the outlet 122. This causes the gas to swirl in the adsorption unit or just entering the adsorption unit, thus increasing the residence time of the gas in the adsorption unit.

[0164] In one possible implementation, refer to Figure 1 The gap at one end of two adjacent adsorption electrodes 100 forms an air inlet 121, and the gap at the other end of two adjacent adsorption electrodes 100 forms an air outlet 122. Gas enters the adsorption unit 10 from the air inlet 121, flows in the airflow channel 110, and leaves the adsorption unit 10 from the air outlet 122.

[0165] Specifically, the airflow channel 110 has at least one bend, such that when the airflow passes through the airflow channel 110, the airflow changes direction at least once along the airflow channel 110, instead of the gas entering from the inlet 121 and flowing directly out from the outlet 122.

[0166] This design causes the gas to swirl within the adsorption unit, increasing its residence time and resulting in more particulate matter deposition, thus improving dust removal efficiency. Furthermore, compared to airflow flowing in a straight channel without changing direction, when the airflow channel is configured to change direction at least once, the adsorption unit has a bend, increasing its surface area and further enhancing adsorption efficiency.

[0167] In one possible implementation, refer to Figure 1 Arrow A indicates the air intake direction. Along the air intake direction A, the projected area S of one or both adsorption electrodes 100 of adjacent adsorption electrodes 100 constituting the air intake 121 or air outlet 122 on the air intake 121 is equal to the area of ​​the air intake 121. Because... Figure 1 This is merely a schematic diagram of the cross-section of the V-shaped adsorption unit, where 'a' represents the projected width. Those skilled in the art will understand that, in the vertical... Figure 1In the direction of the V-shaped adsorption unit, there is a certain height h, the projected area S = ah, and the area of ​​the air inlet is also S.

[0168] With this design, the air inlet 121 and the air outlet 122 are blocked by the adsorption electrode 100. After the airflow enters the adsorption unit 100 and touches the adsorption electrode 100, the flow path changes. This causes the gas to swirl in the adsorption unit, increasing the residence time of the gas in the adsorption unit and improving the dust removal efficiency of particulate matter.

[0169] In one possible implementation, refer to Figure 1 The adsorption electrode 100 includes two adsorption sidewalls 130, the cross-section of the adsorption electrode 100 is V-shaped, and multiple adsorption electrodes 100 are arranged in a fishbone pattern at intervals.

[0170] With this design, the air inlet 121 and the air outlet 122 can be easily blocked by the adsorption electrode 100.

[0171] Specifically, refer to Figure 1 A connecting line is formed at the connection of the adsorption sidewall 120 of the adsorption electrode 100. The adsorption unit 10 includes a first symmetry plane B. The plane where the connecting line of the multiple adsorption electrodes 100 is located is the first symmetry plane B. The two adsorption sidewalls 130 of any adsorption electrode 100 are symmetrically distributed along both sides of the first symmetry plane B, and the adsorption sidewalls 130 on the same side are parallel to each other.

[0172] This design satisfies both the requirement for gas to swirl within the adsorption unit and facilitates the generation and processing.

[0173] In one possible implementation, refer to Figure 1 Two adjacent adsorption sidewalls 130 are connected to each other and form a certain angle, the angle being between 30-120°.

[0174] Figure 2 This is a schematic cross-sectional view of a Z-shaped adsorption unit according to one embodiment of the present invention. In this embodiment, the similarities with the V-shaped adsorption unit will not be repeated; only the differences will be described. The adsorption electrode 200 includes three adsorption sidewalls, and its cross-section is Z-shaped. In other embodiments, the adsorption electrode may include four adsorption sidewalls, and its cross-section is W-shaped; the adsorption electrode may also include five or more adsorption sidewalls, and its cross-section is serrated.

[0175] This design allows for easy multiple swirling of the gas within the adsorption unit, and also facilitates the production and processing.

[0176] Specifically, refer to Figure 2The adsorption electrode 200 includes three adsorption sidewalls 230, and the adsorption unit 20 includes two local symmetry planes C. The adsorption sidewalls 230 of any adsorption electrode 200 are symmetrically distributed along both sides of the local symmetry plane C formed by the two adsorption sidewalls 230, and the adsorption sidewalls 230 on the same side are parallel to each other. Alternatively, the adsorption electrode may include N adsorption sidewalls, and the adsorption unit may include N-1 local symmetry planes, wherein the adsorption sidewalls of any adsorption electrode are symmetrically distributed along both sides of the local symmetry plane formed by the two adsorption sidewalls, and the adsorption sidewalls on the same side are parallel to each other.

[0177] Figure 3 This is a cross-sectional schematic diagram of an arc-shaped adsorption unit according to one embodiment of the present invention. In this embodiment, the similarities with the V-shaped adsorption unit will not be repeated, and only the differences from the V-shaped adsorption unit will be described. The adsorption electrode 300 includes at least one adsorption sidewall 330, the cross-section of which is arc-shaped, wherein the arc-shaped concave direction of adjacent adsorption sidewalls 330 of adjacent adsorption electrodes 300 is the same.

[0178] In one possible implementation, the adsorption electrode includes multiple interconnected adsorption sidewalls, the arcuate concave directions of adjacent adsorption sidewalls of the same adsorption electrode are opposite, the arcuate concave directions of adjacent adsorption sidewalls of adjacent adsorption electrodes are the same, and the cross-section of the adsorption electrode along the airflow direction is wavy.

[0179] Figure 5 This is a cross-sectional schematic diagram of an adsorption unit according to one embodiment of the present invention. Arrow D indicates the air intake direction, that is, the direction in which the airflow enters the airflow channel is direction D; arrow E indicates the direction of the airflow channel. The adsorption unit 90 includes a plurality of adsorption electrodes 900 arranged at intervals. An airflow channel 910 is formed between two adjacent adsorption electrodes 900. The direction D of the airflow entering the airflow channel 910 is different from the direction E of the airflow channel 910.

[0180] This design alters the path of the gas as it enters the adsorption unit, causing it to swirl. This increases the gas's residence time within the adsorption unit, resulting in more particulate matter being deposited and thus improving dust removal efficiency.

[0181] Specifically, refer to Figure 5 The adsorption electrode 900 includes at least one adsorption sidewall 930, the cross-section of which is linear.

[0182] Specifically, refer to Figure 3 The adsorption electrode 300 includes at least one adsorption sidewall 330, and the cross-section of the adsorption sidewall 330 is arc-shaped.

[0183] Specifically, refer to Figure 3The cross-section of the adsorption sidewall 330 is arc-shaped, and the arc-shaped concave direction of the adjacent adsorption sidewalls 530 of the adjacent adsorption electrodes 500 is the same, making the airflow channel 310 arc-shaped.

[0184] Specifically, the adsorption electrode includes multiple interconnected adsorption sidewalls. The arc-shaped concave directions of adjacent adsorption sidewalls of the same adsorption electrode are opposite, while the arc-shaped concave directions of adjacent adsorption sidewalls of adjacent adsorption electrodes are the same. The cross-section of the adsorption electrode is wavy.

[0185] In one possible implementation, the similarities to the above embodiments will not be repeated; only the differences will be described. (Refer to...) Figure 1 The adsorption electrode 100 includes at least two adsorption sidewalls 130, and two adjacent adsorption sidewalls 130 are connected to each other and form a certain angle. The airflow channel 110 includes multiple channels with different directions. The channel adjacent to the airflow inlet is the first channel 111. The direction of the airflow entering the airflow channel 110 is different from the direction of the first channel 111.

[0186] In one possible implementation, the plurality of adsorption electrodes are arranged in parallel.

[0187] In one possible implementation, two adjacent adsorption electrodes may be identical or different.

[0188] Example 2

[0189] Figure 6 This is a schematic diagram of an adsorption unit according to an embodiment of the present invention. The parts identical to those in the above embodiments will not be repeated; only the parts different from the above embodiments will be described. The adsorption unit 810 includes a plurality of spaced-apart adsorption electrodes 8100. Each adsorption electrode 8100 includes at least two adsorption sidewalls 8110. Adjacent adsorption sidewalls 8110 are interconnected and form a certain included angle. An airflow channel 8120 is formed between two adjacent adsorption electrodes 8100. The airflow channel 8120 is configured to allow airflow to flow along the airflow channel 8120 in a manner that changes direction at least once. In this embodiment, because the airflow channel has a bend, the airflow channel 8120 is configured to allow airflow to flow along the airflow channel 8120 in a manner that changes direction once. In other embodiments, the airflow channel has multiple bends, and the airflow channel is configured to allow airflow to flow along the airflow channel in a manner that changes direction more than twice.

[0190] This design causes the gas to swirl within the adsorption unit, increasing the gas's residence time and allowing more particulate matter to deposit, thus improving dust removal efficiency.

[0191] In one possible implementation, refer to Figure 6The adsorption unit 810 includes a plurality of adsorption electrodes 8100 arranged at intervals; an airflow channel 8120 is formed between two adjacent adsorption electrodes 8100, and the airflow channel 8120 is configured such that the airflow entry direction (direction of arrow A) is different from the flow direction along the airflow channel 8120 (direction of arrow B).

[0192] This design causes the gas to swirl when it first enters the adsorption unit, increasing the gas's residence time within the unit and allowing more particulate matter to deposit, thus improving dust removal efficiency.

[0193] In one possible implementation, refer to Figure 6 The adsorption electrode 8100 includes four sequentially connected adsorption sidewalls 8110, and the multiple adsorption electrodes 8100 are arranged in a dovetail shape at intervals. The four sequentially connected adsorption sidewalls 8110 are a first adsorption sidewall 8111, a second adsorption sidewall 8112, a third adsorption sidewall 8113, and a fourth adsorption sidewall 8114. One end of the second adsorption sidewall 8112 and one end of the third adsorption sidewall 8113 are connected to each other so that the cross-sections of the second adsorption sidewall 8112 and the third adsorption sidewall 8113 are V-shaped. The other end of the second adsorption sidewall 8112 extends along the V-shaped opening direction to form the first adsorption sidewall 8111, and the other end of the third adsorption sidewall 8113 extends along the V-shaped opening direction to form the fourth adsorption sidewall 8114.

[0194] With this design, the dovetail shape has certain advantages over the V-shaped structure. For example, it can extend the residence time of the air carrying particles in a swirling and mixing manner, allowing the particles to be fully ionized and adsorbed, thus achieving a higher purification efficiency than the V-shaped structure. The first and fourth adsorption sidewalls of the dovetail-shaped adsorption electrode can increase the adsorption surface of the discharge electrode located therein from the original two surfaces to three surfaces, increasing the adsorption area under the same conditions, so the efficiency will also be higher than that of the V-shaped structure.

[0195] Specifically, refer to Figure 6 The adsorption unit 810 includes a second symmetry plane P, wherein the first adsorption sidewall 8111 and the second adsorption sidewall 8112 of any adsorption electrode 8100 are mirror-symmetrically distributed with respect to the second symmetry plane P.

[0196] Specifically, refer to Figure 6The plurality of spaced-apart adsorption electrodes 8100 include an intermediate adsorption electrode having two adjacent adsorption electrodes 8100, with the two sides of any one intermediate adsorption electrode being a first adjacent adsorption electrode and a second adjacent adsorption electrode, respectively; the first adsorption sidewall 8111, the second adsorption sidewall 8112, the third adsorption sidewall 8113, and the fourth adsorption sidewall 8114 of the intermediate adsorption electrode form the airflow channel 8120 with the second adsorption sidewall 8112 and the third adsorption sidewall 8113 of the first adjacent adsorption electrode; the second adsorption sidewall 8112 and the third adsorption sidewall 8113 of the intermediate adsorption electrode form the airflow channel 8120 with the first adsorption sidewall 8111, the second adsorption sidewall 8112, the third adsorption sidewall 8113, and the fourth adsorption sidewall 8114 of the second adjacent adsorption electrode.

[0197] In one possible implementation, refer to Figure 6 A gap 8130 is formed between the first adsorption sidewall 8111 or the fourth adsorption sidewall 8114 of any adsorption electrode 8100 and the adjacent adsorption electrode 8100, and the gap is an air inlet or an air outlet.

[0198] In one possible implementation, refer to Figure 6 The airflow channel 8120 has a hexagonal cross section, the intersection line of the second symmetry plane P and the hexagonal cross section is the axis of symmetry of the hexagonal cross section, and the shape of the hexagonal cross section after being folded along the axis of symmetry of the hexagonal cross section is a parallelogram.

[0199] Example 3

[0200] In one possible implementation, refer to Figure 4A and Figure 4B An electric field device 400 is provided, which includes a discharge unit 420 and an adsorption unit 410 according to any of the above embodiments (implementations). The discharge unit 420 includes at least one discharge electrode 421, and one or more discharge electrodes 421 are arranged between two adjacent adsorption electrodes 411 of the adsorption unit 410.

[0201] In one possible implementation, refer to Figure 4A and Figure 4B The adsorption electrode 411 includes two adsorption sidewalls, and the cross-section of the adsorption electrode 411 is V-shaped. Multiple adsorption electrodes 411 are arranged in a fishbone pattern with spacing between them. The two adsorption sidewalls of any adsorption electrode 411 are symmetrically distributed along both sides of the first symmetry plane B, and the adsorption sidewalls on the same side are parallel to each other. A discharge electrode 421 is arranged between two adjacent adsorption electrodes 411, and the discharge electrode 421 is located at the first symmetry plane B. For information on the symmetry plane B, please refer to... Figure 1 Understand the relevant descriptions.

[0202] In one possible implementation, refer to Figure 4A The minimum vertical distance y between the discharge electrode 421 and the adjacent adsorption electrode 411 is the same.

[0203] In one possible implementation, refer to Figure 4A and Figure 1 The discharge electrode 421 is at the same vertical distance x from the adjacent adsorption electrode 411 on the plane of symmetry B. In other words, the vertical distance from the discharge electrode 421 to the connecting line of the two adjacent adsorption electrodes 411 is the same.

[0204] In one possible implementation, refer to Figure 4A and Figure 4B The electric field strength of the electric field device 400 is 0.7-1.3 kV / mm.

Here, the electric field strength refers to the ratio between the voltage of the electric field and the discharge distance. The discharge distance is the inter-electrode spacing, that is, the minimum vertical distance y between the discharge electrode and the adsorption electrode. For example, if the voltage of the electric field is 11 kV and the discharge distance is 11.5 mm, the electric field strength = 11 kV / 11.5 mm = 0.957 kV / mm. In this case, the decontamination efficiency is good (no pathogens were detected), and no ozone production was detected. The electric field device in this embodiment has lower energy consumption for the same efficiency.

[0225] Example 5

[0226] Figure 8 This is a three-dimensional schematic diagram of an electric field system according to an embodiment of the present invention. The electric field system 500 includes an adsorption unit 510, a discharge unit (not shown in the figure), and a dust removal unit 520. The adsorption unit 510 and the discharge unit 520 are used to form an electric field. The dust removal unit 520 includes at least one scraper 521, which is movably arranged on the surface of the adsorption unit 510 to remove particulate matter adsorbed on the surface of the adsorption unit 510. The adsorption unit 510 and the discharge unit can be composed of the adsorption unit and the discharge unit in the electric field device described in any of the above embodiments. If the adsorption unit 510 and the discharge unit are composed of the adsorption unit and the discharge unit in the electric field device described in any of the above embodiments, the parts that are the same as those in the above embodiments will not be described again; this section only describes the parts that are different from those in the above embodiments.

[0227] This design can improve the purification efficiency of the electric field system and compensate for the shortcomings of the self-cleaning function of the adsorption unit.

[0228] In one possible implementation, refer to Figure 8 The dust removal unit 520 also includes at least one pull rod 522, which is connected to the scraper 521. By pushing and pulling the pull rod 522, the scraper 521 can be movably arranged on the surface of the adsorption unit 510.

[0229] With this design, the scraper can remove particulate matter adsorbed on the surface of the adsorption unit by a simple push-pull action.

[0230] Specifically, the power source for scraper cleaning can be selected from manual, electric motor, pneumatic, hydraulic, and other methods.

[0231] In one possible implementation, refer to Figure 8 The electric field system 500 also includes a movable cover plate 530, which is arranged at one end of the adsorption unit 510. The movable cover plate 530 is provided with a pull rod hole (not shown in the figure) that matches the pull rod 522, and the pull rod 522 is movably inserted into the pull rod hole.

[0232] With this design, the movable cover plate 530 can fix one end of the adsorption unit 510, preventing arcing and short circuits caused by changes in the position of the adsorption unit 510.

[0233] In one possible implementation, refer to Figure 8The pull rod 522 also includes a first limiting mechanism 5221. The first limiting mechanism 5221 is arranged near the scraper 521 and has a first preset distance from the scraper 521. When the first limiting mechanism 5221 contacts the movable cover plate 530, the movable cover plate 530 is stopped relative to the pull rod 522. The movable cover plate 530 moves with the pull rod 522.

[0234] Specifically, when the dust removal begins and the scraper is pulled, the pull rod 522 is pulled. When the first limiting mechanism 5221 contacts the movable cover plate 530, the movable cover plate 530 is stopped relative to the pull rod 522. If the pull rod 522 is pulled further, the movable cover plate 530 moves together with the pull rod 522. When the dust removal ends and the scraper is returned to its original position, the pull rod 522 is pushed. Because the first limiting mechanism 5221 contacts the movable cover plate 530, the movable cover plate 530 is stopped relative to the pull rod 522. The movable cover plate 530 moves along with the pull rod 522. If the pull rod 522 is pushed further, the first limiting mechanism 5221 leaves the movable cover plate 530, and the movable cover plate 530 stops moving and is positioned at one end of the adsorption unit 510.

[0235] With this design, when the movable cover 530 moves away from the adsorption unit 510 along with the pull rod 522, the scraper 521 can fix one end of the adsorption unit 510, preventing the position of the adsorption unit 510 from changing and causing arcing and short circuit.

[0236] In one possible implementation, refer to Figure 8 The electric field system 500 also includes an upper frame 540 and / or a lower frame 550, which are configured to fix the adsorption unit 510 and / or the discharge unit.

[0237] Figure 8 This is a three-dimensional schematic diagram of an electric field system according to an embodiment of the present invention, wherein the scraper is displaced at the dust collection port. (Refer to...) Figure 8 When the lever 522 is pulled, the movable cover 530 reaches the upper frame 540, thus restricting the movable cover 530 from moving further.

[0238] In one possible implementation, refer to Figure 9 The electric field system 500 also includes a dust removal port 560. When the movable cover plate 530 reaches the upper frame 540, the scraper 521 reaches the dust removal port 560, thus collecting the particulate matter on the scraper 521 from the dust removal port 560.

[0239] In one possible implementation, refer to Figure 8The pull rod 522 also includes a second limiting mechanism 5222, which is arranged near the movable cover plate 530. When the pull rod 522 is pulled, the second limiting mechanism 5222 is configured to prevent the movable cover plate 530 from moving with the pull rod 522 when the first limiting mechanism 5221 does not contact the movable cover plate 530.

[0240] In one possible implementation, refer to Figure 8 The second limiting mechanism 5222 is a sleeve, which is connected to the movable cover plate 530, and the pull rod 522 is movably inserted into the sleeve.

[0241] In one possible implementation, refer to Figure 8 The sleeve is movably installed and arranged on the upper frame 540.

[0242] In one possible implementation, refer to Figure 8 The sidewall of the sleeve includes a grooved track, along which the sleeve moves on the upper frame 540.

[0243] In one possible implementation, refer to Figure 8 The electric field unit 500 also includes a side frame 570.

[0244] In one possible implementation, refer to Figure 8 The side frame 570 is equipped with a dust removal port 560.

[0245] In one possible implementation, refer to Figure 8 The scraper 521 contacts at least a portion of the surface of the adsorption unit 510.

[0246] In one possible implementation, refer to Figure 8 The scraper 521 has at least one opening corresponding to the cross-section of the adsorption unit 510. The shape of the inner surface of the opening includes at least the cross-sectional shape of the adsorption unit 510. The opening is movably fitted onto the surface of the adsorption unit.

[0247] In one possible implementation, refer to Figure 8 The shape of the inner surface of the opening is the same as the cross-sectional shape of the adsorption unit 510 and the discharge unit.

[0248] In one possible implementation, refer to Figure 8 The inner surface of the opening is in contact with the surface of the adsorption unit 510, and is used to scrape off surface particles of the adsorption unit.

[0249] In one possible implementation, refer to Figure 8 The inner surface of the opening has a gap with the surface of the adsorption unit 510, which is used to scrape off some of the surface particles of the adsorption electrode.

[0250] Figure 10 This is a schematic diagram of a scraper according to an embodiment of the present invention, with reference to... Figure 10 The scraper 31 is provided with at least an opening 311 corresponding to the cross-section of the adsorption unit. The shape of the inner surface of the opening 311 includes at least the cross-sectional shape of the adsorption unit. The opening 311 is movably fitted onto the surface of the adsorption unit.

[0251] In one possible implementation, refer to Figure 10 The shape of the inner surface of the opening 311 is the same as the cross-sectional shape of the adsorption unit and the discharge unit.

[0252] In one possible implementation, refer to Figure 10 The inner surface of the opening 311 is in contact with the surface of the adsorption unit and is used to scrape off surface particles of the adsorption unit.

[0253] In one possible implementation, refer to Figure 10 The inner surface of the opening 311 has a gap with the surface of the adsorption unit, which is used to scrape off some of the surface particles of the adsorption unit.

[0254] Example 6

[0255] Figure 11 This is a schematic diagram of the adsorption electrode according to an embodiment of the present invention. Figure 12 It is aimed at Figure 11 A three-dimensional schematic diagram of the electric field system designed for the adsorption electrode. This embodiment (implementation method) only discusses the differences between the adsorption electrode and the above embodiment (implementation method); similarities are not repeated. (Refer to...) Figure 11 and Figure 12 The adsorption electrode 600 includes at least two adsorption sidewalls 610, adjacent adsorption sidewalls 610 are connected to each other and form a certain angle, and one end of at least one adsorption sidewall 610 extends in a direction parallel to the adsorption sidewall to form a first fixing part 620, the first fixing part 620 is configured to be assembled with the upper frame 61 of the electric field system 60.

[0256] With this design, the adsorption electrode can be fixed on the upper frame of the electric field system. When the electric field system is performing dust removal operation, the adsorption electrode can be stably arranged in the electric field system without shaking.

[0257] In one possible implementation, refer to Figure 11 and Figure 12 At least one adsorption sidewall 610 extends at the other end in a direction perpendicular to the adsorption sidewall 610 to form a second fixing part 630, which is configured to be assembled with the lower frame 62 of the electric field system 60.

[0258] With this design, the adsorption electrode can be fixed on the lower frame of the electric field system. When the electric field system is performing dust removal operation, the adsorption electrode can be stably arranged in the electric field system without shaking.

[0259] In one possible implementation, refer to Figure 11 and Figure 12 The second fixing part 630 is assembled with the lower frame 62 of the electric field system 60 by screws.

[0260] This design uses screws for assembly, which is inexpensive, easy to process, and has a simple structure.

[0261] In one possible implementation, refer to Figure 11 and Figure 12 The electric field system 60 also includes a movable cover plate 63, which is arranged at the junction of the first fixed part 620 and the adsorption sidewall 610.

[0262] With this design, although the first fixed part is an extension of the adsorption sidewall and is part of the adsorption electrode, it does not have a dust removal effect when the electric field system removes dust. Therefore, when the electric field system removes dust, the main air inlet is the area between the movable cover and the lower frame. The movable cover can act as a separator, preventing the air to be purified from passing through the first fixed part of the adsorption electrode.

[0263] In one possible implementation, the movable cover plate is provided with a tie rod hole that matches the tie rod, and the tie rod is movably inserted into the tie rod hole.

[0264] In one possible implementation, refer to Figure 11 and Figure 12 The movable cover plate 63 is provided with a fixing port that matches the first fixing part 620, and the movable cover plate 63 is movably sleeved on the first fixing part 620.

[0265] In one possible implementation, refer to Figure 11 and Figure 12 One end of the first adsorption sidewall 611 and the fourth adsorption sidewall 614 extends in a direction parallel to the adsorption sidewall 610 to form a first fixing part 620.

[0266] In one possible implementation, refer to Figure 11 and Figure 12 The other ends of the first adsorption sidewall 611 and the fourth adsorption sidewall 614 extend in a direction perpendicular to the adsorption sidewall to form a second fixing part 630.

[0268] Figure 11 This is a front perspective view of an electric field system according to an embodiment of the present invention.Figure 12 yes Figure 13A A three-dimensional side view of the electric field system, refer to... Figure 13B and Figure 13A The electric field system 700 includes an adsorption unit 710, a discharge unit (not shown in the figure), and a dust removal unit 720. The adsorption unit 710 and the discharge unit are used to form an electric field. The dust removal unit 720 includes at least one scraper 721 and a motor lifting mechanism 722. The motor lifting mechanism 722 is configured to control the scraper 721 to be movably arranged on the surface of the adsorption unit 710 to remove particulate matter adsorbed on the surface of the adsorption unit 710. The adsorption unit 710 and the discharge unit can be composed of the adsorption unit and the discharge unit in the electric field device described in any of the above embodiments. If the adsorption unit 710 and the discharge unit are composed of the adsorption unit and the discharge unit in the electric field device described in any of the above embodiments, the parts that are the same as those in the above embodiments will not be described again; this section only describes the parts that are different from those in the above embodiments. Furthermore, the parts of the electric field system in this embodiment that are the same as those in the electric field system described in any of the above embodiments will not be described again; this section only describes the parts that are different from those in the above embodiments.

[0269] This design improves the efficiency of the electric field purification and compensates for the shortcomings of the self-cleaning function. By controlling the dust removal with a motor, the speed of the scraper movement can be controlled and made more uniform, resulting in a cleaner self-cleaning of the electric field and extending its service life.

[0270] In one possible implementation, refer to Figure 13A and Figure 13B The motor lifting mechanism 722 includes a servo motor 7221, a rotating shaft 7222, a transmission block 7223, and a transmission steel wire 7224. The output shaft of the servo motor 7221 is fixedly connected to the rotating shaft 7222. The rotating shaft 7222 is movably connected to the transmission block 7223 via a thread. The transmission block 7223 is fixedly connected to the first preset position of the transmission steel wire 7224. The scraper 721 is fixedly connected to the second preset position of the transmission steel wire 7224. The servo motor drives the transmission block 7223 to move on the rotating shaft 7222, so that the transmission block 7223 drives the scraper 721 to be movably arranged on the surface of the adsorption unit 710 via the transmission steel wire 7224.

[0271] With this design, the kinetic energy of the servo motor can be easily and conveniently converted into the kinetic energy of the scraper. The up-and-down movement of the transmission block on the rotating shaft drives the movement of the transmission wire, which in turn drives the up-and-down movement of the scraper.

[0272] Specifically, refer to Figure 13A and Figure 13B The rotating shaft 7222 has an external thread, and the transmission block 7223 has an internal thread.

[0273] Specifically, refer to Figure 13A and Figure 13B The transmission block 7223 has an internal threaded hole in the middle, which matches the external thread of the rotating shaft 7222. The two ends of the transmission block 7223 are respectively fixedly connected to two sets of transmission steel wires 7224.

[0274] In one possible implementation, refer to Figure 13A and Figure 13B The electric field system 700 also includes an upper frame 731 and / or a lower frame 732, which are configured to fix the adsorption unit 710 and / or the discharge unit.

[0275] Specifically, one end of the adsorption unit 710 and / or one end of the discharge unit is fixed to the upper frame 731, and the other end of the adsorption unit 710 and / or the other end of the discharge unit is fixed to the lower frame 732.

[0276] This design ensures that both the air intake and exhaust directions are within the area between the upper and lower frames.

[0277] In one possible implementation, refer to Figure 13A and Figure 13B The servo motor 7221 is fixedly connected to the upper frame 731, and the rotating shaft 7222 extends to the lower frame 732; or, the servo motor 7221 is fixedly connected to the lower frame 732, and the rotating shaft 7222 extends to the upper frame 731.

[0278] With this design, the distance the transmission block moves up and down is equal to the distance the scraper moves up and down, so that the scraper can remove particles from any part of the adsorption unit.

[0279] In one possible implementation, refer to Figure 13A and Figure 13B The upper frame 731 and the lower frame 732 are provided with pulleys 740 and transmission wire holes (not shown in the figure). The pulleys 740 are provided with transmission wires 7224, which are movably inserted through the transmission wire holes.

[0280] Specifically, refer to Figure 13A and Figure 13B The transmission wire 7224 is in the shape of a ring. For example, the transmission wire 7224 first passes through the transmission block 7223, then through the upper frame 731, scraper 720, lower frame 732, and finally returns to the transmission block 7223.

[0281] In one possible implementation, refer to Figure 13A and Figure 13BThe electric field system 700 also includes a movable cover plate 750, the adsorption unit 710 is disposed inside the movable cover plate 750, and the movable cover plate 750 is close to one end of the adsorption unit 710.

[0282] With this design, the movable cover can double-fix one end of the adsorption unit, preventing arcing and short circuits caused by changes in the position of the adsorption unit.

[0283] In one possible implementation, refer to Figure 13A and Figure 13B The movable cover plate 750 is provided with a transmission wire hole that matches the transmission wire 7224, and the transmission wire 7224 is movably inserted into the transmission wire hole.

[0284] In one possible implementation, refer to Figure 13A and Figure 13B The scraper 721 is equipped with a limiter 7211. The transmission wire 7224 drives the scraper 721 to move towards the movable cover plate 750. When the limiter 7211 contacts the movable cover plate 750, the transmission wire 7224 drives the scraper 721 and the movable cover plate 750 to continue moving. The distance between the scraper 721 and the movable cover plate 750 is the length of the limiter 7211. Until the movable cover plate 750 reaches the upper frame 731, the movable cover plate 750 and the scraper 721 are restricted from continuing to move.

[0285] In one possible implementation, refer to Figure 13A and Figure 13B The electric field system 700 also includes a dust removal port 760. When the movable cover plate 750 reaches the upper frame 731, the scraper 721 reaches the dust removal port 760 to collect the particles on the scraper 721 from the dust removal port 760.

[0286] With this design, the length of the limiter is just right, and when the movable cover reaches the upper frame, the scraper reaches the dust removal port.

[0287] In one possible implementation, refer to Figure 13A and Figure 13B The lower end of the movable cover 750 is not higher than the lower end of the dust removal port 760.

[0288] Specifically, refer to Figure 13A and Figure 13B A movable cover plate 750 is arranged at the lower end of the dust removal port 760.

[0289] This design prevents polluted air from escaping through the dust collection port.

[0290] In one possible implementation, refer to Figure 13A and Figure 13BThe electric field system 700 also includes a spring 770, one end of which is fixedly connected to a movable cover plate 750, and the other end of which is fixedly connected to an upper cover plate 731.

[0291] With this design, the drive steel wire drives the scraper and the movable cover to continue moving, and the spring is compressed; when the drive steel wire drives the scraper to move towards the lower cover, the movable cover returns to its original position from the upper frame by the spring's rebound.

[0292] In one possible implementation, refer to Figure 13A and Figure 13B The electric field system 700 also includes a guide rod 780, one end of which is fixedly connected to the upper cover plate 731, and the other end passes through the movable cover plate 750 and the scraper 731 until it is fixedly connected to the lower cover plate 732.

[0293] This design makes the scraper blade more stable during its up-and-down movement.

[0294] Specifically, refer to Figure 13A and Figure 13B Spring 770 is sleeved on guide rod 780.

[0295] Specifically, refer to Figure 13A and Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13A Figure 13B Figure 13 The limiter 7211 has a hollow structure, and the guide rod 780 passes through the hollow structure of the limiter 7211.
