[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, the present invention provides a fan.

[0005] In view of this, the present invention provides a fan, including: a housing, the housing is provided with an air inlet and an air outlet; a fan blade, disposed in the housing, for sending air to the air outlet; a dust collection assembly, disposed in the housing, the dust collection assembly is located between the air inlet and the air outlet, the dust collection assembly includes a plurality of electrode plates, the plurality of electrode plates are stacked and wound, and an electric field can be generated between adjacent electrode plates to adsorb a charged medium through the electric field.

[0006] The fan provided by the present invention includes a housing, a fan blade and a dust collection assembly. The fan blade and the dust collection assembly are both disposed in the housing, and the housing plays a protective role for the fan blade and the dust collection assembly. The housing includes an air inlet and an air outlet. The dust collection assembly is disposed between the air inlet and the air outlet. When the fan blade works, it will send air to the air outlet, so that the air flow can flow between the air inlet and the air outlet. Furthermore, the air flow can pass through the dust collection assembly. Among them, the dust collection assembly includes a plurality of electrode plates, and the plurality of electrode plates are stacked and wound, so that an electric field can be generated between adjacent electrode plates. Furthermore, the dust collection assembly can adsorb the charged medium in the passing air flow, so that while the fan is sending air, it can remove dust, disinfect and sterilize the air, realizing the purification of the air, and further avoiding the accumulation of dust inside the fan and improving the comfort of the fan's air supply.

[0007] According to the fan provided by the present invention, the following additional technical features may also be provided:

[0008] In some technical solutions, optionally, the dust collection assembly is located between the fan blade and the air inlet.

[0009] In this technical solution, the dust collection assembly is disposed between the fan blade and the air inlet. The air flow outside the fan enters the housing from the air inlet, then passes through the dust collection assembly. Under the adsorption treatment of the dust collection assembly, dust and other substances in the air are removed. Then the air flow is sent out of the air outlet after passing through the fan blade, which can avoid the dust passing through the fan blade, and thus effectively improve the problem of dust accumulation on the fan blade.

[0010] In some technical solutions, optionally, the fan further includes: an ion generator disposed in the housing for charging the medium, and a plurality of electrode plates can form an electric field after being energized and adsorb the charged medium through the electric field.

[0011] In this technical solution, the fan further includes an ion generator. The ion generator is disposed in the housing and can generate ions, thereby charging the medium entering the housing. The magnetic field generated after the electrode plates are energized can adsorb the charged medium, thereby purifying the airflow passing through the fan and improving the comfort of the fan's air supply. In addition, there is a certain gap between the plurality of electrode plates of the dust collection assembly to form an electric field, which can ensure the performance requirements of both the air blowing and dust collection and purification of the fan on the premise that the air resistance coefficient of the fan meets the conditions.

[0012] In some technical solutions, optionally, the ion generator is disposed on one side of the dust collection assembly, or between the air inlet and the dust collection assembly, or between the air outlet and the dust collection assembly, wherein the ion generator is disposed close to the dust collection assembly.

[0013] In this technical solution, the ion generator is disposed on one side of the dust collection assembly, or between the air inlet and the dust collection assembly, or between the air outlet and the dust collection assembly, so that the ion generator is located in the air duct of the fan. The ion generator can effectively charge the medium, and at the same time shorten the distance for the medium carrying negative ions near the ion generator to diffuse to the dust collection assembly and be adsorbed, improving the dust collection efficiency. Among them, the ion generator is disposed close to the dust collection assembly, further shortening the moving distance for the charged medium to be adsorbed by the dust collection assembly, improving the dust collection efficiency, and preventing the charge generated by the ion generator from being blocked by other components, preventing the influence on the charging effect of the particulate matter.

[0014] In some technical solutions, optionally, the ion generator includes any one of a carbon brush positive ion generator, a carbon brush negative ion generator, a tip positive ion generator, a tip negative ion generator, a needle plate charging device, and a tungsten wire charging device.

[0015] In this technical solution, the ion generator can be any one of the following: a carbon brush positive ion generator, a carbon brush negative ion generator, a tip positive ion generator, a tip negative ion generator, a needle plate charging device, and a tungsten wire charging device.

[0016] In some technical solutions, optionally, the fan further includes: a power supply device disposed in the dust collection assembly or in the housing, and the power supply device is used to supply power to the electrode plates.

[0017] In this technical solution, the fan further includes a power supply device, which is arranged on the dust collection component or on the cover body. The power supply device is connected to the electrode plate and is used to provide a high-voltage power supply for the electrode plate, so as to enable the electrode plate to generate an electric field to adsorb the charged medium.

[0018] In some technical solutions, optionally, the power supply device includes a positive connection pole and a negative connection pole; the plurality of electrode plates include a positive electrode plate and a negative electrode plate, the positive connection pole is electrically connected to the positive electrode plate, and the negative connection pole is electrically connected to the negative electrode plate.

[0019] In this technical solution, the power supply device has a positive connection pole and a negative connection pole, and the plurality of electrode plates include a positive electrode plate and a negative electrode plate. The positive connection pole of the power supply device is connected to the positive electrode plate, and the negative connection pole is electrically connected to the negative electrode plate, so that the power supply device can simultaneously provide a high-voltage power supply for the positive electrode plate and the negative electrode plate, and then an electric field is generated at the gap between the positive electrode plate and the negative electrode plate to adsorb the charged medium.

[0020] In some technical solutions, optionally, the positive electrode plate and the negative electrode plate are alternately stacked in sequence. When the electrode plate is powered on, an electric field can be formed between the positive electrode plate and the negative electrode plate.

[0021] In this technical solution, the positive electrode plate and the negative electrode plate are alternately stacked in sequence, so that an electric field is generated at the gap between the adjacent stacked positive electrode plate and negative electrode plate, and then an adsorption force is generated on the charged medium.

[0022] In some technical solutions, optionally, the electrode plate is a flexible electrode plate.

[0023] In this technical solution, the electrode plate is a flexible electrode plate. After the plurality of electrode plates are stacked, they can be wound into various shapes, thereby reducing the space occupied by the electrode plates and improving the applicability of the dust collection component to meet the requirements of different fans for different electric field forms.

[0024] In some technical solutions, optionally, the dust collection component further includes: a frame, which is detachably arranged in the cover body, and the plurality of electrode plates are stacked in sequence and wound around the frame.

[0025] In this technical solution, the dust collection component further includes a frame, which is detachably arranged in the cover body. After the plurality of electrode plates are stacked in sequence, they are wound around the frame, so that the shape of the wound electrode plate is more firm, avoiding the wound electrode plate from spreading, and then improving the reliability of the electric field generated by the electrode plate and ensuring the dust removal effect of the fan.

[0026] In some technical solutions, optionally, the plurality of electrode plates are stacked in sequence and wound around the center of the frame to form a spiral dust collection structure; or the plurality of electrode plates are stacked in sequence and reciprocally stacked along the circumferential direction of the frame.

[0027] In this technical solution, after multiple electrode plates are stacked in sequence, they are wound around the center of the frame into a spiral dust collection structure, which reduces the space occupation and improves the adsorption effect on the charged medium. Or after multiple electrode plates are stacked in sequence, they are reciprocally stacked along the circumferential direction of the frame. For example, after multiple electrode plates are stacked, they are wound clockwise around the circumferential direction of the frame for one circle, then bent counterclockwise, and stacked on the surface of the previous circle along the counterclockwise direction, and so on to wind into a dust collection component. Of course, it can also be that after multiple electrode plates are stacked, they are wound counterclockwise around the circumferential direction of the frame for one circle, then bent clockwise, and stacked on the surface of the previous circle along the clockwise direction, and so on to wind into a dust collection component.

[0028] In some technical solutions, optionally, when multiple electrode plates are stacked in sequence and wound around the center of the frame into a spiral dust collection structure, the electric field is distributed radially with the winding center of the electrode plate as the center of the circle, and the directions of the electric fields generated between adjacent stacked electrode plates are different.

[0029] In this technical solution, after multiple electrode plates are stacked and wound, gaps are formed between adjacent stacked electrode plates. The spiral dust collection structure makes the electric field in the gaps distributed in a divergent manner with the winding center of the electrode plate as the center of the circle. Furthermore, the distance between the gap and the winding center gradually increases as the number of winding turns increases. Therefore, the dust collection volume gradually increases and the dust collection amount is improved. Specifically, the spiral winding method makes the directions of the electric fields generated in adjacent gaps different.

[0030] Optionally, when multiple electrode plates are stacked in sequence and wound around the center of the frame into a spiral dust collection structure, the electric field is distributed in a divergent manner radially with the winding center of the electrode plate as the center of the circle.

[0031] In some technical solutions, optionally, the frame further includes: a first frame, the first frame includes a first support ring, and the electrode plate is wound around the outer side wall of the first support ring; a second frame, detachably connected to the first frame, the second frame includes a second support ring, and when the first frame and the second frame are buckled, the second support ring passes through the first support ring.

[0032] In this technical solution, the frame further includes a first frame and a second frame, the first frame and the second frame are detachably connected, a first support ring is arranged on the first frame, a second support ring is arranged on the second frame. When assembling the dust collection component, first wind the electrode plate around the first support ring, and then buckle the second frame so that the second support ring of the second frame is inserted into the first support ring. Furthermore, the electrode plate is limited by the first frame and the second frame, which is convenient for winding and encapsulating the electrode plate. At the same time, it can also prevent the wound electrode plate from spreading, and can also hide the wire connecting the electrode plate to the input end of the high-voltage power supply to ensure safety during operation.

[0033] In some technical solutions, optionally, the frame includes an insulating frame; and / or a grille is provided on one side of the frame, and the grille is located on the side of the electrode sheet.

[0034] In this technical solution, the frame includes an insulating frame, which improves the safety performance and avoids the occurrence of electric leakage of the dust collection component. A grille is provided on one side of the frame, and the electrode sheet is located on the side of the grille. The grille can fix the electrode sheet, preventing the electrode sheet from falling or spreading from both sides of the frame, ensuring the stability of the dust collection component, and further ensuring the stability of the electric field.

[0035] In some technical solutions, optionally, any electrode sheet includes a flexible insulating layer and a conductive layer; a plurality of spaced limiting portions are provided on the flexible insulating layer, the conductive layer is provided on one side of the flexible insulating layer, and the limiting portions are located between adjacent stacked conductive layers, so that there is a gap between adjacent conductive layers, and an electric field is generated in the gap under the condition of power on.

[0036] In this technical solution, the electrode sheet includes a flexible insulating layer and a conductive layer. The conductive layer is provided on one side of the flexible insulating layer, and a plurality of limiting portions are provided on the flexible insulating layer. The plurality of limiting portions are spaced apart. When a plurality of electrode sheets are stacked, the limiting portions are located between adjacent conductive layers, providing sufficient gaps between adjacent conductive layers, ensuring the fixation of the gaps between adjacent conductive layers, preventing adjacent conductive layers from contacting, and further ensuring the stability of the electric field generated by the electrode sheet, realizing the adsorption of media such as dust, and eliminating the need to add clamping strips or apply hot melt adhesive to fix the electrode sheet, greatly reducing the process difficulty and processing cost of the dust collection component, and not affecting the appearance of the dust collection component. At the same time, the setting of the limiting portions also increases the distance between adjacent conductive layers, thereby increasing the dust collection area of the dust collection component and improving the dust removal and disinfection effects.

[0037] In some technical solutions, optionally, the conductive layer and the flexible insulating layer are detachably stacked, or the conductive layer is connected to the flexible insulating layer.

[0038] In this technical solution, when the conductive layer and the flexible insulating layer are detachably stacked, it is convenient for cleaning and maintenance of the dust collection component, improving the convenience of dust filtration and cleaning. Moreover, the detachable setting of the conductive layer and the flexible insulating layer can also change the shape of the dust collection component, that is, the conductive layer and the flexible insulating layer can be disassembled and wound into different shapes according to their flexible characteristics, improving the applicability of the dust collection component in different structures and meeting the requirements of the dust collection component for different electric field forms. When the conductive layer is connected to the flexible insulating layer, the conductive layer and the flexible insulating layer can be tightly connected, and the conductive layer and the flexible insulating layer can move together. When the electrode sheet is convolved or bent, the electrode sheet has an adaptive feature.

[0039] In some technical solutions, optionally, when the conductive layer is connected to the flexible insulating layer, the conductive layer is coated or adhered to the flexible insulating layer.

[0040] In this technical solution, the conductive layer is coated or adhered to the flexible insulating layer, which improves the connection strength between the conductive layer and the flexible insulating layer and ensures the convenience during winding.

[0041] In some technical solutions, optionally, the electrode sheet further includes: an insulating substrate, the conductive layer is disposed on the insulating substrate, and when the conductive layer is connected to the flexible insulating layer, the insulating substrate is disposed on the flexible insulating layer.

[0042] In this technical solution, the electrode sheet further includes an insulating substrate, the conductive layer is disposed on the insulating substrate, and then the insulating substrate is connected to the flexible insulating layer, so that the conductive layer is connected to the flexible insulating layer through the insulating substrate, which is convenient for the manufacture of the electrode sheet.

[0043] In some technical solutions, optionally, the limiting portion includes a protrusion, and the protrusion is disposed on the same side or different sides of the flexible insulating layer.

[0044] In this technical solution, the limiting portion includes a protrusion, and the protrusion is disposed on one side or both sides of the flexible insulating layer. The setting of the protrusion can increase the distance between adjacent electrode sheets when multiple electrode sheets are stacked, which on the one hand ensures the stability of the electric field generated by the electrode sheets, and on the other hand increases the dust collection space of the dust collection assembly and improves the dust collection effect. Specifically, the protrusion can be disposed on one side or both sides of the flexible insulating layer.

[0045] In some technical solutions, optionally, the protrusion is disposed on one side of the flexible insulating layer, and the conductive layer is disposed on the other side of the flexible insulating layer.

[0046] In this technical solution, the protrusion and the conductive layer are respectively located on both sides of the flexible insulating layer, which facilitates the connection between the conductive layer and the flexible insulating layer and reduces the processing difficulty.

[0047] In some technical solutions, optionally, the height of the protrusion is greater than or equal to 0.1 mm and less than or equal to 10 mm.

[0048] In this technical solution, the height of the protrusion is set between 0.1 mm and 10 mm, which ensures the spacing effect between adjacent electrode sheets.

[0049] In some technical solutions, optionally, the number of fan blades is one or more. When the number of fan blades is multiple, the multiple fan blades are spaced along the rotation axis direction.

[0050] In this technical solution, the number of fan blades is one or more. When the number of fan blades is multiple, the multiple fan blades are spaced along the rotation axis direction, which can provide various air supply modes.

[0051] In some technical solutions, optionally, the rotation directions of at least two fan blades are the same or different.

[0052] In this technical solution, the rotation directions of at least two fan blades are the same or different. When the rotation directions of at least two fan blades are the same, the air supply distance can be increased. When the rotation directions of at least two fan blades are opposite, a windless air supply can be formed.

[0053] Optionally, the dust collection component, the ion generator and the fan blades are coaxially distributed along the rotation axis direction of the fan blades, improving the purification and dust collection efficiency of the fan.

Detailed implementation manners

[0074] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0075] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0076] Next, refer to Figures 1 to 16 Describe the fan proposed according to some embodiments of the present invention.

[0077] As Figure 1and Figure 2 As shown in Figure 2 , according to an embodiment of the present invention, a fan is proposed, which includes: a housing 1 and a dust collection assembly 3.

[0078] Specifically, the housing 1 is provided with an air inlet 10 and an air outlet 12; a fan blade 2 is arranged inside the housing 1 for sending air to the air outlet 12; the dust collection assembly 3 is arranged inside the housing 1, and the dust collection assembly 3 is located between the air inlet 10 and the air outlet 12; the dust collection assembly 3 includes a plurality of electrode plates 30, and the plurality of electrode plates 30 are stacked and wound, and an electric field can be generated between adjacent electrode plates 30 to adsorb a charged medium through the electric field.

[0079] The fan provided by the present invention includes a housing 1, a fan blade 2 and a dust collection assembly 3. The fan blade 2 and the dust collection assembly 3 are both arranged inside the housing 1, and the housing 1 plays a protective role for the fan blade 2 and the dust collection assembly 3. The housing 1 includes an air inlet 10 and an air outlet 12. The dust collection assembly 3 is arranged between the air inlet 10 and the air outlet 12. When the fan blade 2 works, it will send air to the air outlet 12, so that the air flow can flow between the air inlet 10 and the air outlet 12, and then the air flow can pass through the dust collection assembly 3. Among them, the dust collection assembly 3 includes a plurality of electrode plates 30, and the plurality of electrode plates 30 are stacked and wound, so that an electric field can be generated between adjacent electrode plates 30. Furthermore, the dust collection assembly 3 can adsorb the charged medium in the passing air flow, so that while the fan is sending air, it can remove dust, disinfect and sterilize the air, realize air purification, and then avoid the accumulation of dust inside the fan and improve the comfort of the fan's air supply.

[0080] It can be understood that the dust collection assembly 3 includes a plurality of electrode plates 30. After the plurality of electrode plates 30 are connected to a high-voltage power supply, an electric field can be generated, and the electric field can adsorb the charged dust and also has the function of sterilization and disinfection.

[0081] In some embodiments, optionally, the dust collection assembly 3 is located between the fan blade 2 and the air inlet 10.

[0082] In this embodiment, the dust collection assembly 3 is arranged between the fan blade 2 and the air inlet 10. The air flow outside the fan enters the housing 1 from the air inlet 10, then passes through the dust collection assembly 3. Under the adsorption treatment of the dust collection assembly 3, dust and other substances in the air are removed, and then the air flow is sent out from the air outlet 12 after passing through the fan blade 2, which can avoid the dust passing through the fan blade 2, and thus effectively improve the problem of dust accumulation on the fan blade 2.

[0083] As Figure 1 and Figure 8 shown in Figure 1 and Figure 8 , in some embodiments, optionally, the fan further includes: an ion generator 4, arranged in the housing 1 for charging the medium, and a plurality of electrode plates 30 can form an electric field after being energized and adsorb the charged medium through the electric field.

[0084] In this embodiment, the fan further includes an ion generator 4. The ion generator 4 is disposed in the housing 1. The ion generator 4 can generate ions, so that the medium entering the housing 1 carries charges. The magnetic field generated after the electrode plates 30 are electrified can adsorb the medium carrying charges, so that the air flow passing through the fan is purified, improving the comfort of the fan's air supply. In addition, there is a certain gap between the multiple electrode plates 30 of the dust collection assembly 3 to form an electric field, which can ensure the performance requirements of the fan's air supply blowing and dust collection purification on the premise that the fan's air resistance coefficient meets the conditions.

[0085] It can be understood that the medium includes substances such as dust, bacteria, viruses or other aerosols.

[0086] In some embodiments, optionally, the ion generator 4 is disposed on one side of the dust collection assembly, or between the air inlet 10 and the dust collection assembly 3, or between the air outlet 12 and the dust collection assembly 3. Among them, the ion generator 4 is disposed close to the dust collection assembly 3.

[0087] In this embodiment, the ion generator 4 is disposed on one side of the dust collection assembly 3, or between the air inlet 10 and the dust collection assembly 3, or between the air outlet 12 and the dust collection assembly 3, so that the ion generator 4 is located in the air duct of the fan. The ion generator 4 can effectively make the medium carry charges, and at the same time shorten the distance for the medium carrying negative ions near the ion generator 4 to diffuse to the dust collection assembly 3 and be adsorbed, improving the dust collection efficiency. Among them, the ion generator 4 is disposed close to the dust collection assembly 3, further shortening the moving distance for the medium carrying charges to be adsorbed by the dust collection assembly 3, improving the dust collection efficiency, and preventing the charges generated by the ion generator 4 from being blocked by other components, preventing the influence on the charging effect of particulate matter.

[0088] In some embodiments, optionally, the ion generator 4 includes any one of a carbon brush positive ion generator, a carbon brush negative ion generator, a needle tip positive ion generator, a needle tip negative ion generator, a needle plate charging device, and a tungsten wire charging device.

[0089] In this embodiment, the ion generator 4 can be any one of the following: a carbon brush positive ion generator, a carbon brush negative ion generator, a needle tip positive ion generator, a needle tip negative ion generator, a needle plate charging device, and a tungsten wire charging device.

[0090] As Figure 3 and Figure 5 shown, in some embodiments, optionally, the fan further includes: a power supply device 5, which is disposed in the dust collection assembly 3 or in the housing 1. The power supply device 5 is used to supply power to the electrode plates 30.

[0091] In this embodiment, the fan further includes a power supply device 5, which is disposed on the dust collection assembly 3 or on the cover body 1. The power supply device 5 is connected to the electrode plate 30 and is used to provide a high-voltage power supply for the electrode plate 30, so as to enable the electrode plate 30 to generate an electric field to adsorb the charged medium.

[0092] As Figure 16 shown, in some embodiments, optionally, the power supply device 5 includes a positive connection pole 50 and a negative connection pole 52; the plurality of electrode plates 30 include a positive electrode plate 304 and a negative electrode plate 305. The positive connection pole 50 is electrically connected to the positive electrode plate 304, and the negative connection pole 52 is electrically connected to the negative electrode plate 305.

[0093] In this embodiment, the power supply device 5 has a positive connection pole 50 and a negative connection pole 52. The plurality of electrode plates 30 include a positive electrode plate 304 and a negative electrode plate 305. The positive connection pole 50 of the power supply device 5 is connected to the positive electrode plate 304, and the negative connection pole 52 is electrically connected to the negative electrode plate 305, so that the power supply device 5 can simultaneously provide a high-voltage power supply for the positive electrode plate 304 and the negative electrode plate 305, and then an electric field is generated at the gap between the positive electrode plate 304 and the negative electrode plate 305 to adsorb the charged medium.

[0094] As Figure 6 shown, in some embodiments, optionally, the positive electrode plate 304 and the negative electrode plate 305 are alternately stacked in sequence. When the electrode plate 30 is powered on, an electric field can be formed between the positive electrode plate 304 and the negative electrode plate 305.

[0095] In this embodiment, the positive electrode plate 304 and the negative electrode plate 305 are alternately stacked in sequence, so that an electric field is generated at the gap between the adjacent stacked positive electrode plate 304 and negative electrode plate 305, and then an adsorption force is generated on the charged medium.

[0096] In a specific application, after the positive electrode plate 304 and the negative electrode plate 305 are stacked, they are wound around the frame 32.

[0097] As Figure 5 and Figure 6 shown, in some embodiments, optionally, the electrode plate 30 is a flexible electrode plate, and the plurality of electrode plates 30 are stacked in sequence and wound.

[0098] In this embodiment, the electrode plate 30 is a flexible electrode plate. After the plurality of electrode plates 30 are stacked, they can be wound into various shapes, thereby reducing the space occupied by the electrode plate 30 and improving the applicability of the dust collection assembly 3 to meet the requirements of different fans for different electric field forms.

[0099] It can be understood that the electrode sheet 30 is a flexible electrode sheet, that is, the shape of the electrode sheet 30 is variable, and the electrode sheet 30 can be bent according to specific actual usage requirements to adjust the shape of the electrode sheet 30. For example, the electrode sheet 30 can be bent into an annular structure, for example, the electrode sheet 30 can be bent into an "S" - shaped structure, for example, the electrode sheet 30 can be bent into a spiral structure. That is to say, by bending the electrode sheet 30, the requirements for the electric - field area generated during the operation of the dust - collecting assembly 3 can be met. In this way, compared with the related art where multiple groups of electrode members are arranged alternately and in parallel, it is beneficial to reduce the number of electrode sheets 30, simplify the assembly process of the dust - collecting assembly 3, reduce the production cost of the dust - collecting assembly, generate a larger electric - field area with fewer electrode sheets 30, and has the advantages of diverse shapes and strong adaptability.

[0100] Such as Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in ,

[0100] , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , in some embodiments, optionally, the dust - collecting assembly 3 further includes: a frame 32, detachably disposed in the housing 1, and a plurality of electrode sheets 30 are sequentially stacked and wound around the frame 32.

[0101] In this embodiment, the dust - collecting assembly 3 further includes a frame 32. The frame 32 is detachably disposed in the housing 1, and a plurality of electrode sheets 30 are sequentially stacked and then wound around the frame 32, making the shape of the wound electrode sheet 30 more firm, preventing the wound electrode sheet 30 from spreading, thereby improving the reliability of the electric field generated by the electrode sheet 30 and ensuring the dust - removal effect of the fan.

[0102] Optionally, the power - supply device 5 is disposed in the middle of the frame 32.

[0103] In some embodiments, optionally, a plurality of electrode sheets 30 are sequentially stacked and wound around the center of the frame 32 to form a spiral dust - collecting structure; or a plurality of electrode sheets 30 are sequentially stacked and reciprocally stacked along the circumferential direction of the frame 32.

[0104] In this embodiment, after a plurality of electrode sheets 30 are sequentially stacked, they are wound around the center of the frame 32 to form a spiral dust - collecting structure, reducing the space occupation and improving the adsorption effect on the charged medium. Or after a plurality of electrode sheets 30 are sequentially stacked, they are reciprocally stacked along the circumferential direction of the frame 32. For example, after a plurality of electrode sheets 30 are stacked, they are wound clockwise around the circumferential direction of the frame 32 for one circle, then bent counter - clockwise, and stacked on the surface of the previous circle along the counter - clockwise direction, and so on to wind into the dust - collecting assembly 3. Of course, it can also be that after a plurality of electrode sheets 30 are stacked, they are wound counter - clockwise around the circumferential direction of the frame 32 for one circle, then bent clockwise, and stacked on the surface of the previous circle along the clockwise direction, and so on to wind into the dust - collecting assembly 3.

[0105] As Figure 13 and Figure 14 shown, in some embodiments, optionally, in the case where a plurality of electrode sheets 30 are sequentially stacked and wound around the center of the frame 32 to form a spiral dust collection structure, the electric field is divergently distributed in the radial direction with the winding center of the electrode sheet 30 as the center of the circle, and the directions of the electric fields generated between adjacent stacked electrode sheets 30 are different.

[0106] In this embodiment, after a plurality of electrode sheets 30 are stacked and wound, a gap is formed between adjacent stacked electrode sheets 30. The spiral dust collection structure enables the electric field in the gap to be divergently distributed with the winding center of the electrode sheet 30 as the center of the circle. Furthermore, the distance between the gap and the winding center gradually increases as the number of winding turns increases. Therefore, the dust collection volume gradually increases, improving the dust collection capacity. Specifically, the spiral winding method makes the directions of the electric fields generated in adjacent gaps different.

[0107] Among them, as Figure 13 shown, the direction of the electric field is indicated by the dotted arrow. Specifically, the electric field is divergently arranged along the normal direction with the winding center of the electrode sheet 30 as the center. As Figure 14 shown, in adjacent stacked electrode sheets 30, an electric field is formed from the positive electrode sheet 304 to the negative electrode sheet 305, and the directions of adjacent electric fields are all different.

[0108] As Figure 3 , Figure 4 and Figure 7 shown, in some embodiments, optionally, the frame 32 further includes: a first frame 320, the first frame 320 includes a first support ring 322, and the electrode sheet 30 is wound around the outer sidewall of the first support ring 322; a second frame 324, detachably connected to the first frame 320, the second frame 324 includes a second support ring 326, and in the case where the first frame 320 and the second frame 324 are buckled, the second support ring 326 passes through the inside of the first support ring 322.

[0109] In this embodiment, the frame 32 further includes a first frame 320 and a second frame 324, the first frame 320 and the second frame 324 are detachably connected, the first frame 320 is provided with a first support ring 322, and the second frame 324 is provided with a second support ring 326. When assembling the dust collection assembly 3, first wind the electrode sheet 30 around the first support ring 322, and then buckle the second frame 324 so that the second support ring 326 of the second frame 324 is inserted into the first support ring 322. Furthermore, the electrode sheet 30 is limited by the first frame 320 and the second frame 324, facilitating the winding and encapsulation of the electrode sheet 30. At the same time, it can also prevent the wound electrode sheet 30 from spreading, and can also hide the wire connecting the electrode sheet 30 to the input end of the high-voltage power supply, ensuring safety during operation.

[0110] Optionally, the power supply device 5 is disposed within the first support ring 322.

[0111] In some embodiments, optionally, the frame 32 includes an insulating frame; and / or a grille 328 is provided on one side of the frame 32, and the grille 328 is located on the side of the electrode sheet 30.

[0112] In this embodiment, the frame 32 includes an insulating frame, which improves the safety performance and avoids the occurrence of electric leakage of the dust collection assembly 3. A grille 328 is provided on one side of the frame 32, and the electrode sheet 30 is located on the side of the grille 328. The grille 328 can fix the electrode sheet 30, preventing the electrode sheet 30 from falling or spreading from both sides of the frame 32, ensuring the stability of the dust collection assembly 3, and thus ensuring the stability of the electric field.

[0113] Specifically, after the electrode sheet 30 and the frame 32 are assembled, grilles 328 are provided on both sides of the electrode sheet 30.

[0114] In some embodiments, optionally, any one of the electrode sheets 30 includes a flexible insulating layer 300 and a conductive layer 302. A plurality of spaced-apart limiting portions 301 are provided on the flexible insulating layer 300. The conductive layer 302 is disposed on one side of the flexible insulating layer 300, and the limiting portions 301 are located between adjacent stacked conductive layers 302, so that there is a gap between adjacent conductive layers 302, and an electric field is generated in the gap under the condition of power-on.

[0115] In this embodiment, as Figure 9 、 Figure 10 、 Figure 11 and Figure 12 shown, the electrode sheet 30 includes a flexible insulating layer 300 and a conductive layer 302. The conductive layer 302 is disposed on one side of the flexible insulating layer 300. A plurality of limiting portions 301 are provided on the flexible insulating layer 300, and the plurality of limiting portions 301 are spaced apart. When a plurality of electrode sheets 30 are stacked, the limiting portions 301 are located between adjacent conductive layers 302, providing sufficient gaps between adjacent conductive layers 302, ensuring the fixation of the gaps between adjacent conductive layers 302, preventing adjacent conductive layers 302 from contacting each other, thus ensuring the stability of the electric field generated by the electrode sheet 30, realizing the adsorption of media such as dust, and eliminating the need to add clamping strips or apply hot melt adhesive to fix the electrode sheet 30, greatly reducing the process difficulty and processing cost of the dust collection assembly 3, without affecting the appearance of the dust collection assembly 3. At the same time, the setting of the limiting portions 301 also increases the distance between adjacent conductive layers 302, thereby increasing the dust collection area of the dust collection assembly 3 and improving the dust removal and disinfection effects.

[0116] In some embodiments, optionally, the conductive layer 302 and the flexible insulating layer 300 are detachably stacked, or the conductive layer 302 is connected to the flexible insulating layer 300.

[0117] In this embodiment, when the conductive layer 302 and the flexible insulating layer 300 are detachably stacked, it is convenient to clean and repair the dust collection assembly 3, improving the convenience of dust filtration and cleaning. Moreover, the detachable setting of the conductive layer 302 and the flexible insulating layer 300 can also make the shape of the dust collection assembly 3 changeable. That is, the conductive layer 302 and the flexible insulating layer 300 can be disassembled and wound into different shapes according to their flexible characteristics, improving the applicability of the dust collection assembly 3 in different structures and meeting the requirements of the dust collection assembly 3 for different electric field forms. When the conductive layer 302 is connected to the flexible insulating layer 300, the conductive layer 302 and the flexible insulating layer 300 can be closely connected, and the conductive layer 302 and the flexible insulating layer 300 can move together. Thus, when the electrode sheet 30 is convolved or bent, the electrode sheet 30 has an adaptive feature.

[0118] In some embodiments, optionally, when the conductive layer 302 is connected to the flexible insulating layer 300, the conductive layer 302 is coated or adhered to the flexible insulating layer 300.

[0119] In this embodiment, the conductive layer 302 is coated or adhered on the flexible insulating layer 300, improving the connection strength between the conductive layer 302 and the flexible insulating layer 300 and ensuring the convenience during winding.

[0120] As Figure 15 shown, in some embodiments, optionally, the electrode sheet 30 further includes: an insulating substrate 303, the conductive layer 302 is disposed on the insulating substrate 303, and when the conductive layer 302 is connected to the flexible insulating layer 300, the insulating substrate 303 is disposed on the flexible insulating layer 300.

[0121] In this embodiment, the electrode sheet 30 further includes an insulating substrate 303, the conductive layer 302 is disposed on the insulating substrate 303, and the insulating substrate 303 is then connected to the flexible insulating layer 300, such that the conductive layer 302 is connected to the flexible insulating layer 300 through the insulating substrate 303, facilitating the manufacture of the electrode sheet 30.

[0122] Optionally, the side of the insulating substrate 303 where the conductive layer 302 is disposed is connected to the flexible insulating layer 300.

[0123] In this embodiment, the side of the insulating substrate 303 where the conductive layer 302 is disposed is connected to the flexible insulating layer 300, such that the two sides of the conductive layer 302 are respectively the flexible insulating layer 300 and the insulating substrate 303. Thus, the conductive layer 302 is completely sealed by the insulating substrate 303 and the flexible insulating layer 300, and the surface of the electrode sheet 30 is completely insulated. When powered on and operating, the occurrence of electric leakage can be avoided, improving the safety performance.

[0124] Optionally, the conductive layer 302 is coated or adhered to the insulating substrate 303.

[0125] In this embodiment, the conductive layer 302 is coated or adhered to the insulating substrate 303, so that the conductive layer 302 and the insulating substrate 303 are connected into an integral structure, improving the connection strength and reliability between the conductive layer 302 and the insulating substrate 303, and further ensuring the stability of the distance between adjacent electrode sheets 30 and the stability of the electric field.

[0126] Optionally, the insulating substrate 303 is adhered to the flexible insulating layer 300.

[0127] In this embodiment, the insulating substrate 303 is adhered to the flexible insulating layer 300, so that the insulating substrate 303 and the flexible insulating layer 300 are adhered into an integral structure, improving the reliability of the connection between the insulating substrate 303 and the flexible insulating layer 300, and avoiding the separation of the conductive layer 302 from the flexible insulating layer 300.

[0128] Optionally, the insulating substrate 303 includes any one of PC, PET, PP, and PS; and / or the thickness of the insulating substrate 303 is greater than or equal to 0.1 mm and less than or equal to 1.0 mm.

[0129] In this embodiment, the insulating substrate 303 includes any one of polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), and polystyrene (PS). The thickness of the insulating substrate 303 is set between 0.1 mm and 1 mm, ensuring the insulation performance of the electrode sheet 30.

[0130] In a specific application, the thickness of the insulating substrate 303 is any value among 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, and 1.0 mm.

[0131] As Figure 9 shown, in some embodiments, optionally, the limiting portion 301 includes a protrusion 3011, and the protrusion 3011 is provided on the same side or different sides of the flexible insulating layer 300.

[0132] In this embodiment, the limiting portion 301 includes a protrusion 3011. The protrusion 3011 is provided on one or both sides of the flexible insulating layer 300. The provision of the protrusion 3011 can increase the distance between adjacent electrode sheets 30 when a plurality of electrode sheets 30 are stacked. On the one hand, it ensures the stability of the electric field generated by the electrode sheets 30. On the other hand, it also increases the dust collection space of the dust collection assembly 3 and improves the dust collection effect. Specifically, the protrusion 3011 can be provided on one or both sides of the flexible insulating layer 300.

[0133] In some embodiments, optionally, the protrusion 3011 is provided on one side of the flexible insulating layer 300, and the conductive layer 302 is provided on the other side of the flexible insulating layer 300.

[0134] In this embodiment, the protrusion 3011 and the conductive layer 302 are respectively located on both sides of the flexible insulating layer 300, which facilitates the connection between the conductive layer 302 and the flexible insulating layer 300 and reduces the processing difficulty.

[0135] As Figure 11 shown, in some embodiments, optionally, the height C of the protrusion 3011 is greater than or equal to 0.1 mm and less than or equal to 10 mm.

[0136] In this embodiment, the height C of the protrusion 3011 is set between 0.1 mm and 10 mm, ensuring the spacing effect between adjacent electrode sheets 30.

[0137] Optionally, in any cross-section perpendicular to the height direction of the protrusion 3011, the width A between any two points on the contour line of the protrusion 3011 is greater than or equal to 0.1 mm and less than or equal to 10 mm; and / or the spacing B between adjacent protrusions 3011 is greater than or equal to 0.5 mm and less than or equal to 100 mm; and / or the difference in height between any two protrusions 3011 is greater than or equal to 0 mm and less than or equal to 1 mm.

[0138] In this design, if the width A of the protrusion 3011 is too large, it will increase the manufacturing cost and reduce the volume of the dust collection space. If the width A of the protrusion 3011 is too small, it will increase the manufacturing difficulty. Therefore, the width A between any two points on the contour line of any cross-section of the protrusion 3011 is set between 0.1 mm and 10 mm, which can not only ensure the volume of the dust collection space but also facilitate manufacturing. Optionally, the spacing B between adjacent protrusions 3011 is set between 0.5 mm and 100 mm. Optionally, the difference in height between any two protrusions 3011 is less than or equal to 0 mm and less than or equal to 1 mm, so that the heights of multiple protrusions 3011 are close to each other, and thus the distance between the electrode sheets 30 is maintained within a stable range.

[0139] It can be understood that the height C of the protrusion 3011 is also the height by which the protrusion 3011 protrudes from the flexible insulating layer 300.

[0140] In a specific application, in any cross-section perpendicular to the height direction of the protrusion 3011, the width A (i.e., the width of the protrusion 3011) between any two points on the contour line of the protrusion 3011 is any value among 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, or is between any two values.

[0141] Optionally, the spacing B between adjacent protrusions 3011 is greater than or equal to 2 mm and less than or equal to 100 mm. Specifically, the spacing between adjacent protrusions 3011 is any value among 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, or is between any two values.

[0142] Optionally, the height C of the protrusion 3011 is any value among 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or is between any two values.

[0143] Optionally, multiple protrusions 3011 are set to be of equal height.

[0144] Optionally, the edge of the conductive layer 302 is located within the region enclosed by the edges of the flexible insulating layer 300.

[0145] In this embodiment, the edge of the conductive layer 302 is located within the region enclosed by the edges of the flexible insulating layer 300, such that the projection of the conductive layer 302 on the flexible insulating layer 300 is within the flexible insulating layer 300, improving the creepage distance and the electrical clearance and avoiding the occurrence of discharge and sparking phenomena.

[0146] Optionally, along the width direction of the flexible insulating layer 300, the distance from the edge of the conductive layer 302 to the edge of the flexible insulating layer 300 is greater than or equal to 1 mm and less than or equal to 50 mm.

[0147] In this embodiment, along the width direction of the flexible insulating layer 300, the distance from the edge of the conductive layer 302 to the edge of the flexible insulating layer 300 is greater than or equal to 1 mm and less than or equal to 50 mm, which not only ensures the electrical clearance but also can ensure the range of electric field coverage.

[0148] In a specific application, along the width direction of the flexible insulating layer 300, the distance from the edge of the conductive layer 302 to the edge of the flexible insulating layer 300 is any value among 2 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm, 50 mm.

[0149] Optionally, the flexible insulating layer 300 includes an insulating film or an insulating plastic sheet.

[0150] In this embodiment, the flexible insulating layer 300 includes an insulating film or an insulating plastic sheet, which can not only achieve winding but also ensure the insulation effect between adjacent electrode sheets 30.

[0151] Optionally, the thickness of the flexible insulating layer 300 is greater than or equal to 0.1 mm and less than or equal to 1 mm.

[0152] In this embodiment, the thickness of the flexible insulating layer 300 is between 0.1 mm and 1 mm, which can achieve insulation between adjacent electrode sheets 30.

[0153] In a specific application, the thickness of the flexible insulating layer 300 is any value among 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, or is between any two values.

[0154] Optionally, the conductive layer 302 includes any one of a metal foil, a conductive thin film, or a flexible conductive sheet coated with a conductive coating.

[0155] In this embodiment, the conductive layer 302 includes any one of a metal foil, a conductive thin film, or a flexible conductive sheet coated with a conductive coating.

[0156] Optionally, the surface resistance of the conductive layer 302 is less than or equal to 1×10 8 Ω.

[0157] In this embodiment, the surface resistance of the conductive layer 302 is less than or equal to 1×10 8 Ω, ensuring that when the electrode sheet 30 is long, the applied voltage will not show a significant attenuation.

[0158] As Figure 12 shown, optionally, the electrode sheet 30 further includes: an electrical connection portion 3020, the electrical connection portion 3020 is electrically connected to the conductive layer 302, and the electrical connection portion 3020 is used to connect to the power supply device 5.

[0159] In this embodiment, the electrode sheet 30 further includes an electrical connection portion 3020, the electrical connection portion 3020 is connected to the conductive layer 302, and can be connected to the power supply device 5, thereby providing a high-voltage power supply for the electrode sheet 30 so that the electrode sheet 30 can generate a corresponding electric field to achieve dust adsorption.

[0163] Optionally, the electrical connection portion 3020 includes a metal part or a wire.

[0164] In this embodiment, the electrical connection portion 3020 includes structures such as a metal part or a wire that can achieve electrical conductivity.

[0165] In some embodiments, optionally, the number of the fan blades 2 is one or more. When the number of the fan blades 2 is multiple, the multiple fan blades 2 are arranged at intervals along the rotation axis direction.

[0166] In this embodiment, the number of the fan blades 2 is one or more. When the number of the fan blades 2 is multiple, the multiple fan blades 2 are arranged at intervals along the rotation axis direction, which can provide multiple air supply modes.

[0167] Optionally, when the number of the fan blades 2 is multiple, the dust collection assembly 3 is arranged between the multiple fan blades 2 and the air inlet 10.

[0168] In some embodiments, optionally, the rotation directions of at least two fan blades 2 are the same or different.

[0169] In this embodiment, the rotation directions of at least two fan blades 2 are the same or different. When the rotation directions of at least two fan blades 2 are the same, the air supply distance can be increased. When the rotation directions of at least two fan blades 2 are opposite, a windless air supply can be formed.

[0170] Optionally, the dust collection assembly 3, the ion generator 4 and the fan blades 2 are coaxially distributed along the rotation axis direction of the fan blades 2, which improves the purification and dust collection efficiency of the fan.

[0171] Specifically, the present invention relates to the field of air purification, specifically to purification and sterilization filters and purification fans. It mainly introduces a filter screen (such as the dust collection assembly 3) made of an adaptive flexible electrode. The filter screen includes a positive electrode and a negative electrode, and the positive electrode and the negative electrode are made of an adaptive flexible electrode and wound in parallel into a spiral structure. The filter screen has the characteristics of low wind resistance, high efficiency and simple process. The fan applying this spiral structure has the effects of dust removal and sterilization.

[0172] The electrostatic purification dust collection device (such as the dust collection component 3) has the effects of dust removal and sterilization and disinfection, and has a very low air resistance, which can meet the application scenarios with strict requirements for air resistance, such as air conditioners, fans, heaters, etc.; however, since the electrostatic purification dust collection device mainly relies on an electric field to complete the adsorption and sterilization of particulate matter, the electrodes generating the electric field need to be spaced apart, parallel to each other, and respectively connected to the high-voltage output terminal and the low-voltage output terminal of the high-voltage power supply, resulting in a relatively complex manufacturing process for the current integrated device, a relatively high manufacturing cost, and a single form, thus also limiting the scope of use of this technology. In the related art, in terms of controlling the distance between the positive and negative plates, an external spacer or hot melt adhesive is used. On the one hand, the processing accuracy cannot be guaranteed, and on the other hand, fine manual operation is required, resulting in a high processing cost.

[0173] The filter screen made of an adaptive flexible electrode includes a flexible electrode sheet and a support frame (such as the frame 32). The flexible electrode sheet is divided into a positive electrode (such as the positive electrode sheet) and a negative electrode (such as the negative electrode sheet), which are respectively connected to the high-voltage output terminal and the low-voltage output terminal of the high-voltage power supply during operation. Both the positive electrode and the negative electrode are flexible electrode sheets with a limiting structure (such as the limiting portion 301). The positive electrode and the negative electrode are wound parallel to each other at one end of the support frame, and the assembly of the filter screen can be completed by buckling with the other end of the support frame. A grille 328 is provided on the surface of the support frame. The core purification component of the fan using this filter screen also includes an ion generator 4 and a high-voltage power supply (such as the power supply device 5). During the operation of the fan, the ion generator 4 charges the particulate matter in the air, and the high-voltage power supply energizes the positive electrode and the negative electrode of the filter screen, forming an electric field between the positive and negative electrodes, thereby adsorbing the charged particulate matter. At the same time, the electric field also has the effect of sterilization and disinfection.

[0174] The filter screen made of an adaptive flexible electrode includes a flexible electrode sheet with a limiting structure and a support frame.

[0175] The flexible electrode sheet with a limiting structure includes a conductive layer 302 and a limiting structure insulating layer (such as the flexible insulating layer 300). The limiting structure is a number of protrusions 3011 provided on the surface of the insulating layer. The supporting effect of the protrusions 3011 can control the electric field distance between the positive electrode and the negative electrode to be between 0.1 mm and 10 mm.

[0176] The flexible electrode sheet with a limiting structure includes 1 positive electrode with a limiting structure and 1 negative electrode with a limiting structure. The positive electrode and the negative electrode are wound parallel to each other on the support frame to form a spiral filter screen body.

[0177] The support frame is made of an insulating material. The flexible electrode sheet is wound along the central axis direction of the support frame. A grille 328 is provided on the support frame, which can fix the spirally wound flexible electrode sheet so that it will not fall off or spread from the front and back, maintaining the stability of the filter screen structure.

[0178] For the convenience of winding and encapsulation, the support frame can be set as a detachable part. First, the flexible electrode sheet is wound around one side of the support frame (such as the first frame 320), and then it is snapped together with another component (such as the second frame 324) to achieve the encapsulation and fixation of the filter screen. The support frame can ensure the stable shape of the filter screen and can also hide the wires connected to the positive and negative electrodes at the high-voltage power input end to ensure safety during operation.

[0179] When the filter screen is installed for use with the fan, it needs to be used in conjunction with the ion generator 4 and the high-voltage power supply. The filter screen is preferably installed at the air inlet 10 of the fan, which can effectively alleviate the problem of dust accumulation on the main body of the fan.

[0180] The ion generator 4 can be set on the air duct path, preferably at the air outlet 12 of the fan or at a position close to the filter screen at the air inlet 10. This can prevent the generated ions from being blocked by other components in the air duct and affecting the charging effect of the particulate matter.

[0181] The main function of the ion generator 4 is to charge the particulate matter, and it can be a carbon brush positive / negative ion generator 4, a needle tip positive / negative ion generator 4, a needle plate charging device, a tungsten wire charging device, etc.

[0182] The high-voltage power supply can be set on the filter screen or the whole machine, and it mainly supplies power to the positive and negative electrodes of the filter screen.

[0183] The adaptive flexible electrode sheet can be directly wound into a filter screen with a special-shaped structure, controlling the distance between the positive and negative electrodes of the dust collection component 3, greatly reducing the processing difficulty and processing cost of the filter screen. At the same time, the protrusion 3011 can also increase the dust collection area of the filter screen and improve the dust removal and disinfection effect of the filter screen.
