Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and more specifically, to a fan.

Background Art

[0002] In related technologies, when a fan operates, it can promote the flow of ambient air. However, after the fan operates for a long time, more dust accumulates on the fan blades, which affects the comfort of the fan for supplying air.

Summary of the Invention

Problems to be Solved by the Invention

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

Means for Solving the Problems

[0004] For this purpose, the present invention provides a fan.

[0005] Based on this, the present invention includes a cover body provided with an air inlet and an air outlet, a fan blade provided in the cover body and used to supply air to the air outlet, and a dust collection assembly provided in the cover body. The dust collection assembly is located between the air inlet and the air outlet. The dust collection assembly includes a plurality of electrode sheets, and the plurality of electrode sheets are arranged to be laminated and wound, generating an electric field between adjacent electrode sheets, and capable of adsorbing a charged medium through the electric field, and provides a fan.

[0006] The fan provided by the present invention comprises a cover body, fan blades, and a dust collection assembly, both of which are located within the cover body, and the cover body serves to protect the fan blades and the dust collection assembly. The cover body includes an intake port and an exhaust port, and the dust collection assembly is located between the intake port and the exhaust port. When the fan blades are operating, they supply air to the exhaust port, causing the airflow to flow between the intake port and the exhaust port, thereby allowing the airflow to pass through the dust collection assembly. The dust collection assembly comprises a plurality of electrode sheets, which are arranged to be stacked and wound together, generating an electric field between adjacent electrode sheets, thereby allowing the dust collection assembly to attract charged media in the passing airflow. This enables the fan to purify the air by performing dust removal, disinfection, and sterilization on the air while supplying it, thereby preventing dust from accumulating inside the fan and improving the comfort of the air supplying fan.

[0007] The fan provided by the present invention may further have the following additional technical features:

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

[0009] In this technical solution, the dust collection assembly is positioned between the fan blades and the air intake. The airflow from outside the fan flows into the cover body through the air intake, then passes through the dust collection assembly. The dust collection assembly removes dust and other substances from the air through its adsorption process. The airflow then passes through the fan blades and is expelled from the exhaust port, preventing dust from passing through the fan blades and thereby effectively improving the problem of dust accumulation on the fan blades.

[0010] In some technical solutions, the fan is optionally provided on the cover body and used to carry charge to the medium, further including an ion generator that forms an electric field after multiple electrode sheets are energized and can attract the charged medium through the electric field.

[0011] In this technical solution, the fan further includes an ion generator, which is mounted on the cover body. The ion generator generates ions, which cause the medium flowing into the cover body to carry an electric charge. The magnetic field generated after the electrode sheets are energized can attract the charged medium, thereby purifying the airflow passing through the fan and improving the comfort of the fan supplying air. Furthermore, there is a certain gap between the multiple electrode sheets of the dust collection assembly to form an electric field, and assuming the fan's wind resistance coefficient meets the requirements, the performance requirements for both airflow and dust collection can be simultaneously ensured.

[0012] In some technical solutions, the ion generator is optionally located on one side of the dust collection assembly, or between the intake port and the dust collection assembly, or between the exhaust port and the dust collection assembly, where the ion generator is positioned in close proximity to the dust collection assembly.

[0013] In this technical solution, the ion generator is positioned on one side of the dust collection assembly, or between the intake port and the dust collection assembly, or between the exhaust port and the dust collection assembly, thereby positioning the ion generator within the fan's air duct. The ion generator effectively carries charge to the medium while simultaneously shortening the distance over which the negatively charged medium near the ion generator diffuses and is adsorbed by the dust collection assembly, thereby improving dust collection efficiency. Here, the ion generator is positioned close to the dust collection assembly, further shortening the distance over which the charged medium is adsorbed by the dust collection assembly, improving dust collection efficiency, and preventing the charge generated by the ion generator from being blocked by other components, thus preventing any impact on the charging effect of granules.

[0014] In some technical solutions, the ion generator can be selected from among 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, or a tungsten wire charging device.

[0015] In this technical solution, the ion generator may be any 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, a tungsten wire charging device, etc.

[0016] In some technical solutions, the fan optionally further includes a power supply unit located in the dust collection assembly or cover body, which is used to supply power to the electrode sheet.

[0017] In this technical solution, the fan further includes a power supply, which is located on the dust collection assembly or in the cover body, and the power supply is connected to an electrode sheet and used to supply high voltage power to the electrode sheet, thereby generating an electric field on the electrode sheet to achieve the adsorption of a charged medium.

[0018] In some technical solutions, the power supply unit may optionally include a positive and a negative connection terminal, and the electrode sheets may include a positive electrode sheet and a negative electrode sheet, with the positive connection terminal being electrically connected to the positive electrode sheet and the negative connection terminal being electrically connected to the negative electrode sheet.

[0019] In this technical solution, the power supply unit has a positive and a negative connection terminal, and the multiple electrode sheets include a positive electrode sheet and a negative electrode sheet. The positive connection terminal of the power supply unit is connected to the positive electrode sheet, and the negative connection terminal is electrically connected to the negative electrode sheet. As a result, the power supply unit can simultaneously supply high voltage power to the positive and negative electrode sheets, thereby generating an electric field in the gap between the positive and negative electrode sheets, achieving the adsorption of the charged medium.

[0020] In some technical solutions, optionally, a positive electrode sheet and a negative electrode sheet are alternately laminated in sequence, and when the electrode sheet is energized, an electric field can be formed between the positive electrode sheet and the negative electrode sheet.

[0021] In this technical solution, the positive electrode sheet and the negative electrode sheet are alternately laminated in sequence, and an electric field is generated in the gap between the adjacent positive electrode sheet and negative electrode sheet after lamination, thereby generating an adsorption force on the charged medium.

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

[0023] In this technical solution, the electrode sheet is a flexible electrode sheet, and after a plurality of electrode sheets are laminated, they can be wound into various forms, thereby reducing the space occupied by the electrode sheet, improving the applicability of the dust collection assembly, and meeting the requirements of various fans for various electric field forms.

[0024] In some technical solutions, optionally, the dust collection assembly further includes a frame detachably provided in the cover body, and a plurality of electrode sheets are laminated in sequence and wound around the frame.

[0025] In this technical solution, the dust collection assembly further includes a frame, the frame is detachably arranged in the cover body, and after a plurality of electrode sheets are laminated in sequence, they are wound on the frame, thereby making the shape of the wound electrode sheet stronger, preventing the spread of the wound electrode sheet, thereby improving the reliability of the electric field generated by the electrode sheet, and ensuring the dust removal effect of the fan.

[0026] In some technical solutions, optionally, a plurality of electrode sheets are laminated in sequence and wound into a spiral dust collection structure around the center of the frame, or a plurality of electrode sheets are laminated in sequence and arranged to be reciprocally laminated along the circumferential direction of the frame.

[0027] In this technical solution, after a plurality of electrode sheets are arranged to be stacked in sequence, they are then wound into a spiral dust collection structure around the center of the frame, reducing the occupied space and improving the adsorption effect on the charged medium. Or after a plurality of electrode sheets are stacked in sequence, they are stacked back and forth along the circumferential direction of the frame. For example, after a plurality of electrode sheets are stacked, they are wound one round clockwise along the circumferential direction of the frame, then bent counterclockwise, and stacked on the surface of the previous round along the counterclockwise direction. In this way, they are wound back and forth on the dust collection assembly. Of course, after a plurality of electrode sheets are stacked, they are wound one round counterclockwise along the circumferential direction of the frame, then bent clockwise, and stacked on the surface of the previous round along the clockwise direction. In this way, they are wound back and forth on the dust collection assembly.

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

[0029] In this technical solution, after a plurality of electrode sheets are stacked and wound, a gap is formed between adjacent stacked electrode sheets. Due to the spiral dust collection structure, the electric field in the gap is divergently distributed with the winding center of the electrode sheet as the center of the circle. As a result, the distance between the gap and the winding center gradually increases as the number of winding turns increases, so the dust collection volume gradually increases and the dust collection amount is increased. Specifically, in the spiral winding mode, the directions of the electric fields generated in adjacent gaps are different.

[0030] Optionally, when a plurality of electrode sheets are stacked in sequence and wound into a spiral dust collection structure around the center of the frame, the electric field is divergently distributed radially along the radial direction with the winding center of the electrode sheet as the center of the circle.

[0031] In some technical solutions, the frame optionally includes a first support ring, and the electrode sheet further includes a first frame wrapped around the outer wall of the first support ring, and a second frame detachably connected to the first frame and including a second support ring, wherein when the first frame and the second frame are engaged, the second support ring is installed 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 being detachably connected, the first frame having a first support ring, and the second frame having a second support ring, and when the dust collection assembly is assembled, the electrode sheet is first wound onto the first support ring, and then the second frame is re-engaged so that the second support ring of the second frame is inserted into the first support ring, thereby using the first frame and the second frame to position the electrode sheet, thereby facilitating the winding and packaging of the electrode sheet, while simultaneously preventing the electrode sheet from unraveling after winding, concealing the wiring connecting the electrode sheet to the input terminal of the high-voltage power, and ensuring safety during operation.

[0033] In some technical solutions, the frame may optionally include an insulating frame and / or a grid provided on one side of the frame, with the grid located on the side of the electrode sheet.

[0034] In this technical solution, the frame includes an insulating frame to improve safety performance and prevent power leakage from the dust collection assembly. A grid is provided on one side of the frame, and the electrode sheet is located on the side of the grid. The grid secures the electrode sheet, preventing it from falling or spreading from either side of the frame, thus ensuring the stability of the dust collection assembly and, consequently, the stability of the electric field.

[0035] In some technical solutions, an optional electrode sheet includes a flexible insulating layer and a conductive layer, with multiple spaced positional limits provided on the flexible insulating layer, the conductive layer provided on one side of the flexible insulating layer, and the positional limits located between adjacent laminated conductive layers, thereby creating a gap between adjacent conductive layers, and when current is applied, an electric field is generated within the gap.

[0036] In this technical solution, the electrode sheet includes a flexible insulating layer and a conductive layer. The conductive layer is positioned on one side of the flexible insulating layer, and multiple position limiting sections are positioned on the flexible insulating layer. These position limiting sections are spaced apart, and when multiple electrode sheets are laminated, the position limiting sections are located between adjacent conductive layers, providing sufficient space between them and ensuring that the gaps between adjacent conductive layers are fixed, preventing contact between adjacent conductive layers, thereby ensuring the stability of the electric field generated on the electrode sheet and enabling the adsorption of dust and other media. Furthermore, since there is no need to install additional clamp strips or apply hot melt adhesive to fix the electrode sheet, the technical difficulty and processing cost of the dust collection assembly are greatly reduced, and the appearance of the dust collection assembly is not affected. At the same time, the arrangement of the position limiting sections also increases the distance between adjacent conductive layers, thereby increasing the dust collection area of ​​the dust collection assembly and improving the dust removal and sterilization effect.

[0037] In some technical solutions, the conductive layer and the flexible insulating layer are either laminated in a removable manner, or the conductive layer and the flexible insulating layer are bonded together.

[0038] In this technical solution, when the conductive layer and the flexible insulating layer are laminated in a removable manner, cleaning and maintenance of the dust collection assembly can be facilitated, improving the convenience of dust filtration and cleaning. Furthermore, the conductive layer and the flexible insulating layer are arranged in a removable manner, allowing the configuration of the dust collection assembly to be changed; that is, the conductive layer and the flexible insulating layer can be disassembled and wound into different shapes according to their flexible properties, improving the applicability of the dust collection assembly in different structures and meeting the requirements of the dust collection assembly for various electric field configurations. When the conductive layer and the flexible insulating layer are connected, they are tightly connected, and the conductive layer and the flexible insulating layer can move together, thereby winding or bending the electrode sheet, which then has adaptive properties.

[0039] In some technical solutions, when a conductive layer and a flexible insulating layer are connected, the conductive layer is coated or bonded to the flexible insulating layer.

[0040] In this technical solution, the conductive layer is coated or bonded onto the flexible insulating layer, thereby improving the connection strength between the conductive layer and the flexible insulating layer and ensuring convenience during winding.

[0041] In some technical solutions, the electrode sheet optionally includes an insulating base, and the conductive layer is provided on the insulating base, and if the conductive layer and the flexible insulating layer are connected, the insulating base is provided on the flexible insulating layer.

[0042] In this technical solution, the electrode sheet further includes an insulating base, the conductive layer is placed on the insulating base, and the insulating base is reconnected to a flexible insulating layer, thereby connecting the conductive layer to the flexible insulating layer via the insulating base, which facilitates the manufacture of the electrode sheet.

[0043] In some technical solutions, the position limiting portion may optionally include a projection, which may be located on the same side or different sides of the flexible insulating layer.

[0044] In this technical solution, the position limiting portion includes a projection, which is positioned on one or both sides of the flexible insulating layer. When the arrangement of the projections results in multiple electrode sheets being stacked, the distance between adjacent electrode sheets can be increased, ensuring the stability of the electric field generated on the electrode sheets, and increasing the dust collection space of the dust collection assembly, thereby improving the dust collection effect. Specifically, the projection can be positioned on one or both sides of the flexible insulating layer.

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

[0046] In this technical solution, the protrusions and conductive layer are located on either side of the flexible insulating layer, thereby facilitating the connection between the conductive layer and the flexible insulating layer and reducing the difficulty of processing.

[0047] In some technical solutions, the height of the protrusion can be selected to be between 0.1 mm and 10 mm.

[0048] In this technical solution, the height of the protrusions is set between 0.1 mm and 10 mm to ensure spacing between adjacent electrode sheets.

[0049] In some technical solutions, the number of fan blades can be one or more, and if there are multiple fan blades, the multiple fan blades are spaced apart along the direction of the rotation axis.

[0050] In this technical solution, the number of fan blades may be one or more, and if there are multiple fan blades, the multiple fan blades are spaced apart along the rotational axis direction, which can provide various air supply modes.

[0051] In some technical solutions, the rotation direction of at least two fan blades can be either the same or different, as a matter of choice.

[0052] In this technical solution, the rotation directions of at least two fan blades are either the same or different. If the rotation directions of at least two fan blades are the same, the distance over which air is supplied can be increased, and if the rotation directions of at least two fan blades are opposite, a still air supply can be formed.

[0053] Selectively, the dust collection assembly, ion generator, and fan blades are distributed coaxially along the rotation axis of the fan blades to improve the fan's purification and dust collection efficiency.

[0057] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. To the extent that it does not contradict the description, the embodiments and features described herein can be combined with each other.

[0058] Many specific details are provided in the following description to facilitate a full understanding of the present invention, but the present invention can also be carried out in other ways as described herein, and therefore the scope of protection of the present invention is not limited by the specific examples disclosed below.

[0059] The fans proposed by several embodiments of the present invention will be described below with reference to Figures 1 to 16.

[0060] As shown in Figures 1 and 2, based on one embodiment of the present invention, the present invention provides a fan including a cover body 1 and a dust collection assembly 3.

[0061] Specifically, the cover body 1 is provided with an air intake port 10 and an exhaust port 12, the fan blades 2 are provided inside the cover body 1 and used to supply air to the exhaust port 12, the dust collection assembly 3 is provided inside the cover body 1 and is located between the air intake port 10 and the exhaust port 12, the dust collection assembly 3 includes a plurality of electrode sheets 30, the plurality of electrode sheets 30 are arranged to be stacked and wound, and an electric field is generated between adjacent electrode sheets 30, which can attract charged media through the electric field.

[0062] The fan provided by the present invention comprises a cover body 1, fan blades 2, and a dust collection assembly 3, the fan blades 2 and the dust collection assembly 3 all being housed within the cover body 1, and the cover body 1 serves to protect the fan blades 2 and the dust collection assembly 3. The cover body 1 includes an air intake port 10 and an exhaust port 12. The dust collection assembly 3 is positioned between the air intake port 10 and the exhaust port 12. When the fan blades 2 are operating, the exhaust port 12 also supplies air, allowing the airflow to flow between the air intake port 10 and the exhaust port 12, thereby allowing the airflow to pass through the dust collection assembly 3. The dust collection assembly 3 includes a plurality of electrode sheets 30, which are arranged to be stacked and wound together, thereby generating an electric field between adjacent electrode sheets 30. This allows the dust collection assembly 3 to attract charged media in the passing airflow. As a result, the fan purifies the air by removing dust, disinfecting, and sterilizing it while supplying air, preventing dust from accumulating inside the fan and improving the comfort of the fan supplying air.

[0063] It should be understood that the dust collection assembly 3 includes multiple electrode sheets 30, which can generate an electric field when connected to high voltage power, and that this electric field can generate charged dust, while simultaneously having a sterilizing and disinfecting effect.

[0064] In some embodiments, the dust collection assembly 3 is optionally located between the fan blades 2 and the air intake 10.

[0065] In this embodiment, the dust collection assembly 3 is positioned between the fan blades 2 and the air intake port 10. The airflow outside the fan flows into the cover body 1 through the air intake port 10, then passes through the dust collection assembly 3, where dust and other substances in the air are removed by the adsorption process of the dust collection assembly 3. The airflow then passes through the fan blades 2 and is discharged from the exhaust port 12, preventing dust from passing through the fan blades 2, thereby effectively improving the problem of dust accumulation on the fan blades 2.

[0066] As shown in Figures 1 to 8, in some embodiments, the fan optionally includes an ion generator 4 provided on the cover body 1, which allows the medium to carry charge, forms an electric field after the multiple electrode sheets 30 are energized, and can attract the charged medium through the electric field.

[0067] In this embodiment, the fan further includes an ion generator 4, which is located on the cover body 1. The ion generator 4 can generate ions, thereby carrying an electric charge to the medium entering the cover body 1. The magnetic field generated after the electrode sheet 30 is energized can attract the charged medium, thereby purifying the airflow passing through the fan and improving the comfort of the fan supplying air. Furthermore, there is a certain gap between the multiple electrode sheets 30 of the dust collection assembly 3 to form an electric field, and assuming the fan's wind resistance coefficient meets the requirements, the performance requirements for airflow and dust collection purification can be simultaneously ensured.

[0068] Please understand that the medium may contain substances such as dust, bacteria, viruses, or other aerosols.

[0069] In some embodiments, the ion generator 4 is optionally located on one side of the dust collection assembly, or positioned between the intake port 10 and the dust collection assembly 3, or between the exhaust port 12 and the dust collection assembly 3, where the ion generator 4 is positioned in close proximity to the dust collection assembly 3.

[0070] In this embodiment, the ion generator 4 is positioned on one side of the dust collection assembly 3, or between the intake port 10 and the dust collection assembly 3, or between the exhaust port 12 and the dust collection assembly 3, thereby positioning the ion generator 4 within the fan's air duct, allowing the ion generator 4 to effectively carry charge to the medium, and simultaneously shortening the distance over which the negatively charged medium near the ion generator 4 diffuses and is adsorbed by the dust collection assembly 3, thereby improving dust collection efficiency. Here, the ion generator 4 is positioned close to the dust collection assembly 3, further shortening the distance the charged medium travels before being adsorbed by the dust collection assembly 3, improving dust collection efficiency, and preventing the charge generated by the ion generator 4 from being blocked by other components, thus preventing its influence on the charging effect of granular materials.

[0071] In some embodiments, the ion generator 4 may optionally include 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, or a tungsten wire charging device.

[0072] In this embodiment, the ion generator 4 may be any 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, a tungsten wire charging device, etc.

[0073] As shown in Figures 3 and 5, in some embodiments, the fan optionally includes a power supply unit 5, which is provided on the dust collection assembly 3 or the cover body 1 and is used to supply power to the electrode sheet 30.

[0074] In this embodiment, the fan further includes a power supply unit 5, which is located on the dust collection assembly 3 or on the cover body 1, and the power supply unit 5 and the electrode sheet 30 are connected and used to supply high voltage power to the electrode sheet 30, thereby generating an electric field on the electrode sheet 30 and achieving the adsorption of an electrically charged medium.

[0075] As shown in Figure 16, in some embodiments, the power supply 5 optionally includes a positive connection electrode 50 and a negative connection electrode 52, and the plurality of electrode sheets 30 include a positive electrode sheet 304 and a negative electrode sheet 305, with the positive connection electrode 50 being electrically connected to the positive electrode sheet 304 and the negative connection electrode 52 being electrically connected to the negative electrode sheet 305.

[0076] In this embodiment, the power supply unit 5 has a positive connection electrode 50 and a negative connection electrode 52, and the plurality of electrode sheets 30 include a positive electrode sheet 304 and a negative electrode sheet 305. The positive connection electrode 50 of the power supply unit 5 is connected to the positive electrode sheet 304, and the negative connection electrode 52 is electrically connected to the negative electrode sheet 305. The power supply unit 5 simultaneously supplies high voltage power to the positive electrode sheet 304 and the negative electrode sheet 305, thereby generating an electric field in the gap between the positive electrode sheet 304 and the negative electrode sheet 305, achieving the adsorption of the charged medium.

[0077] As shown in Figure 6, in some embodiments, the positive electrode sheet 304 and the negative electrode sheet 305 are selectively stacked alternately in sequence, and when current is applied to the electrode sheet 30, an electric field can be formed between the positive electrode sheet 304 and the negative electrode sheet 305.

[0078] In this embodiment, the positive electrode sheet 304 and the negative electrode sheet 305 are stacked alternately in sequence, and an electric field is generated in the gap between adjacent stacked positive electrode sheets 304 and negative electrode sheets 305, thereby generating an attractive force on the charged medium.

[0079] In a specific application, the positive electrode sheet 304 and the negative electrode sheet 305 are arranged in a stacked manner and then wound onto the frame 32.

[0080] As shown in Figures 5 and 6, in some embodiments, the electrode sheet 30 is optionally a flexible electrode sheet, and multiple electrode sheets 30 are arranged to be stacked in sequence and wound around each other.

[0081] In this embodiment, the electrode sheet 30 is a flexible electrode sheet, and multiple electrode sheets 30 can be wound into various forms after being laminated, thereby reducing the space occupied by the electrode sheets 30, improving the applicability of the dust collection assembly 3, and meeting the requirements of various fans for various electric field configurations.

[0082] The electrode sheet 30 is a flexible electrode sheet, meaning its shape is variable. It should be understood that the electrode sheet 30 can be bent to adjust its shape according to specific actual usage requirements. For example, the electrode sheet 30 can be bent into an annular structure, into an "S" shape, or into a spiral structure. In other words, by bending the electrode sheet 30, the requirements for the electric field region generated when the dust collection assembly 3 is in operation can be met. This reduces the number of electrode sheets 30 compared to the conventional method of arranging multiple groups of electrode members parallel to each other, simplifying the assembly process of the dust collection assembly 3, reducing the production cost of the dust collection assembly 3, and offering the advantages of generating a larger electric field region with fewer electrode sheets 30, as well as diverse shapes and high adaptability.

[0083] As shown in Figures 3, 4, 5, 6, and 7, in some embodiments, the dust collection assembly 3 optionally further includes a frame 32, which is detachably provided within the cover body 1, and a plurality of electrode sheets 30 are stacked in sequence and wrapped around the frame 32.

[0084] In this embodiment, the dust collection assembly 3 further includes a frame 32 which is detachably disposed within the cover body 1, and the multiple electrode sheets 30 are stacked in order and then wound onto the frame 32, thereby making the shape of the electrode sheets 30 more rigid after winding, preventing the electrode sheets 30 from spreading after winding, thereby improving the reliability of the electric field generated on the electrode sheets 30 and ensuring the dust removal effect of the fan.

[0085] Selectively, the power supply unit 5 is positioned in the center of the frame 32.

[0086] In some embodiments, the electrode sheets 30 are selectively stacked in sequence and wound around a spiral dust collection structure around the center of the frame 32, or the electrode sheets 30 are stacked in sequence and arranged to reciprocate along the circumferential direction of the frame 32.

[0087] In this embodiment, after the multiple electrode sheets 30 are arranged to be stacked in order, a spiral dust collection structure is wound around the center of the frame 32, thereby reducing the occupied space and improving the adsorption effect on the charged medium. Alternatively, after the multiple electrode sheets 30 are stacked in order, they are stacked reciprocally along the circumferential direction of the frame 32. For example, after the multiple electrode sheets 30 are stacked, they are wound one round clockwise in the circumferential direction of the frame 32, then bent counterclockwise and stacked on the surface of the previous round along the counterclockwise direction, thus winding reciprocally around the dust collection assembly 3. Of course, after the multiple electrode sheets 30 are stacked, they can be wound one round counterclockwise in the circumferential direction of the frame 32, then bent clockwise and stacked on the surface of the previous round along the clockwise direction, thus winding reciprocally around the dust collection assembly 3.

[0088] As shown in Figures 13 and 14, in some embodiments, when multiple electrode sheets 30 are selectively stacked in sequence and wound into a spiral dust collection structure around the center of the frame 32, the electric field is distributed radially divergently with the winding center of the electrode sheet 30 as the center of the circle, and the direction of the electric field generated between adjacent stacked electrode sheets 30 is different.

[0089] In this embodiment, after multiple electrode sheets 30 are stacked and wound, gaps are formed between adjacent stacked electrode sheets 30. Due to the helical dust collection structure, the electric field within the gaps is distributed divergently with the winding center of the electrode sheets 30 as the center of the circle. As a result, the distance between the gaps and the winding center gradually increases as the number of windings increases, thus gradually increasing the dust collection volume and increasing the amount of dust collected. Specifically, in the helical winding mode, the directions of the electric fields generated in adjacent gaps are different.

[0090] Here, as shown in Figure 13, the dotted arrows indicate the direction of the electric field, specifically, the electric field is divergently distributed along the normal direction from the winding center of the electrode sheet 30. As shown in Figure 14, in adjacent stacked electrode sheets 30, an electric field is formed in the direction from the positive electrode sheet 304 to the negative electrode sheet 305, and the directions of the electric fields of adjacent sheets are all different.

[0091] As shown in Figures 3, 4 and 7, in some embodiments, the frame 32 optionally includes a first frame 320 which includes a first support ring 322 and on which the electrode sheet 30 is wrapped around the outer wall of the first support ring 322, and a second frame 324 which is detachably connected to the first frame 320 and includes a second support ring 326 which, when the first frame 320 and the second frame 324 are engaged, is installed through the first support ring 322.

[0092] 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 being detachably connected, a first support ring 322 positioned on the first frame 320, and a second support ring 326 positioned on the second frame 324. When the dust collection assembly 3 is assembled, first the electrode sheet 30 is wound onto the first support ring 322, then re-engaged with the second frame 324, the second support ring 326 of the second frame 324 being inserted into the first support ring 322, thereby achieving positional constraints on the electrode sheet 30 through the first frame 320 and the second frame 324, facilitating the winding and packaging of the electrode sheet 30, while simultaneously preventing the electrode sheet 30 from unfolding after winding, concealing the wiring connecting the electrode sheet 30 to the high-voltage power input terminal, and ensuring safety during operation.

[0093] Selectively, the power supply unit 5 is positioned within the first support ring 322.

[0094] In some embodiments, the frame 32 optionally includes an insulating frame and / or a grid 328 is provided on one side of the frame 32, the grid 328 being located on the side of the electrode sheet 30.

[0095] In this embodiment, the frame 32 includes an insulating frame to improve safety performance and prevent situations of power leakage from the dust collection assembly 3. A grid 328 is provided on one side of the frame 32, and the electrode sheet 30 is located on the side of the grid 328. The grid 328 can fix the electrode sheet 30 in place, preventing it from falling or spreading from either side of the frame 32, thereby ensuring the stability of the dust collection assembly 3 and, consequently, the stability of the electric field.

[0096] Specifically, after the electrode sheet 30 and frame 32 are assembled, grids 328 are placed on both sides of the electrode sheet 30.

[0097] In some embodiments, optionally, the electrode sheet 30 comprises a flexible insulating layer 300 and a conductive layer 302, wherein the flexible insulating layer 300 is provided with a plurality of spaced position limiting portions 301, the conductive layer 302 is provided on one side of the flexible insulating layer 300, the position limiting portions 301 are located between adjacent laminated conductive layers 302, and a gap exists between adjacent conductive layers 302, and when current is applied, an electric field is generated in the gap.

[0098] In this embodiment, as shown in Figures 9, 10, 11, and 12, the electrode sheet 30 includes a flexible insulating layer 300 and a conductive layer 302. The conductive layer 302 is positioned on one side of the flexible insulating layer 300, and multiple position limiting portions 301 are positioned on the flexible insulating layer 300. The multiple position limiting portions 301 are spaced apart, and when multiple electrode sheets 30 are laminated, the position limiting portions 301 are positioned between adjacent conductive layers 302, providing sufficient space between adjacent conductive layers 302. This ensures that the gaps between adjacent conductive layers 302 are fixed, preventing contact between adjacent conductive layers 302, thereby ensuring the stability of the electric field generated on the electrode sheets 30, enabling the adsorption of dust and other media. Furthermore, there is no need to install additional clamp strips or apply hot melt adhesive to fix the electrode sheets 30, significantly reducing the technical difficulty and processing cost of the dust collection assembly 3, and without affecting the appearance of the dust collection assembly 3. At the same time, the position limiting portions 301 increase 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 sterilization effect.

[0099] In some embodiments, the conductive layer 302 is optionally removably grounded to the flexible insulating layer 300, or the conductive layer 302 is connected to the flexible insulating layer 300.

[0100] In this embodiment, when the conductive layer 302 is removably laminated to the flexible insulating layer 300, cleaning and maintenance of the dust collection assembly 3 are facilitated, and the convenience of dust filtration and cleaning is improved. Furthermore, the conductive layer 302 is removably positioned on the flexible insulating layer 300, and the configuration of the dust collection assembly 3 can be changed. The conductive layer 302 and the flexible insulating layer 300 can also be separated, and depending on their flexible properties, they can be wound into different shapes, 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 configurations. When the conductive layer 302 is connected to the flexible insulating layer 300, the conductive layer 302 can be tightly connected to the flexible insulating layer 300, and the conductive layer 302 and the flexible insulating layer 300 can move together, thereby causing the electrode sheet 30 to be wound or bent, and the electrode sheet 30 has adaptive properties.

[0101] In some embodiments, if the conductive layer 302 is optionally connected to the flexible insulating layer 300, the conductive layer 302 is coated or bonded to the flexible insulating layer 300.

[0102] In this embodiment, the conductive layer 302 is coated or bonded to the flexible insulating layer 300 to improve the connection strength between the conductive layer 302 and the flexible insulating layer 300 and to ensure convenience during winding.

[0103] As shown in Figure 15, in some embodiments, the electrode sheet 30 optionally further includes an insulating base 303, and the conductive layer 302 is provided on the insulating base 303, and the insulating base 303 is provided on the flexible insulating layer 300 when the conductive layer 302 is connected to a flexible insulating layer 300.

[0104] In this embodiment, the electrode sheet 30 further includes an insulating base 303, the conductive layer 302 is placed on the insulating base 303, the insulating base 303 is reconnected to a flexible insulating layer 300, and the conductive layer 302 is connected to the flexible insulating layer 300 via the insulating base 303, thereby facilitating the manufacture of the electrode sheet 30.

[0105] Selectively, one side of the insulating base 303, which is provided with the conductive layer 302, is connected to the flexible insulating layer 300.

[0106] In this embodiment, one side of the insulating base 303 on which the conductive layer 302 is provided is connected to the flexible insulating layer 300, so that both sides of the conductive layer 302 are the flexible insulating layer 300 and the insulating base 303, respectively. As a result, the conductive layer 302 is completely sealed by the insulating base 303 and the flexible insulating layer 300, the surface of the electrode sheet 30 is completely insulated, and when operated by power, the occurrence of power leakage can be prevented, improving safety performance.

[0107] The conductive layer 302 is optionally coated or bonded to the insulating substrate 303.

[0108] In this embodiment, the conductive layer 302 is coated or bonded to the insulating base 303, so that the conductive layer 302 is integrally connected to the insulating base 303, improving the connection strength and reliability between the conductive layer 302 and the insulating base 303, thereby ensuring the stability of the distance and electric field between adjacent electrode sheets 30.

[0109] Optionally, the insulating base 303 is bonded to the flexible insulating layer 300.

[0110] In this embodiment, the insulating base 303 is bonded onto the flexible insulating layer 300, thereby integrally bonding the insulating base 303 to the flexible insulating layer 300, improving the reliability of the connection between the insulating base 303 and the flexible insulating layer 300, and preventing the occurrence of a situation in which the conductive layer 302 and the flexible insulating layer 300 separate.

[0111] The insulating base 303 may be selected to include PC, PET, PP, or PS, and / or the thickness of the insulating base 303 may be between 0.1 mm and 1.0 mm.

[0112] In this embodiment, the insulating base 303 includes one of the following: polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), or polystyrene (PS). The thickness of the insulating base 303 is set between 0.1 mm and 1 mm to ensure the insulating performance of the electrode sheet 30.

[0113] In specific applications, the thickness of the insulating substrate 303 is one of the following values: 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, or 1.0 mm.

[0114] As shown in Figure 9, in some embodiments, the position limiting portion 301 optionally includes a projection 3011, which is provided on the same side or different sides of the flexible insulating layer 300.

[0115] In this embodiment, the position limiting portion 301 includes a projection 3011, which is arranged on one or both sides of the flexible insulating layer 300. The arrangement of the projection 3011 allows multiple electrode sheets 30 to be stacked, thereby increasing the distance between adjacent electrode sheets 30, ensuring the stability of the electric field generated on the electrode sheets 30, and increasing the dust collection space of the dust collection assembly 3, thereby improving the dust collection effect. Specifically, the projection 3011 can be arranged on one or both sides of the flexible insulating layer 300.

[0116] In some embodiments, the projection 3011 is optionally 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.

[0117] In this embodiment, the protrusion 3011 and the conductive layer 302 are located on both sides of the flexible insulating layer 300, thereby facilitating connection between the conductive layer 302 and the flexible insulating layer 300 and reducing the difficulty of processing.

[0118] As shown in Figure 11, in some embodiments, the height C of the projection 3011 is selectably between 0.1 mm and 10 mm.

[0119] In this embodiment, the height C of the projection 3011 is set between 0.1 mm and 10 mm to ensure spacing between adjacent electrode sheets 30.

[0120] Selectively, in any cross section perpendicular to the height direction of the projection 3011, the width A between any two points on the contour line of the projection 3011 is 0.1 mm or more and 10 mm or less, and / or the distance B between adjacent projections 3011 is 0.5 mm or more and 100 mm or less, and / or the height difference between any two projections 3011 is 0 mm or more and 1 mm or less.

[0121] In this design, if the width A of the protrusion 3011 is too large, manufacturing costs will increase and the volume of the dust collection space will decrease. If the width A of the protrusion 3011 is too small, the difficulty of manufacturing will increase. Therefore, by setting the width A between any two points on the contour line of any cross-section of the protrusion 3011 to between 0.1 mm and 10 mm, it is possible to secure the volume of the dust collection space and to facilitate manufacturing. Selectively, the distance B between adjacent protrusions 3011 can be set to between 0.5 mm and 100 mm. Selectively, the height difference between any two protrusions 3011 is between 0 mm and 1 mm, so that the heights of multiple protrusions 3011 are close to each other, thereby maintaining the distance between the electrode sheets 30 within a stable range.

[0122] Please understand that the height C of the projection 3011 is the height to which the projection 3011 protrudes from the flexible insulating layer 300.

[0123] In a specific application, in any cross section perpendicular to the height direction of the projection 3011, the width A between any two points on the contour line of the projection 3011 (i.e., the width of the projection 3011) is one of the following values: 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 between any two of these values.

[0124] Selectively, the distance B between adjacent protrusions 3011 is between 2 mm and 100 mm. Specifically, the distance between adjacent protrusions 3011 is one of the following values: 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, or 90 mm, or between any two of these values.

[0125] Selectively, the height C of projection 3011 may be one of the following values: 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or between any two of these values.

[0126] Multiple protrusions 3011 are set to the same height for selection.

[0127] Selectively, the edges of the conductive layer 302 are located within the region enclosed by the edges of the flexible insulating layer 300.

[0128] In this embodiment, the edges of the conductive layer 302 are located within the region enclosed by the edges of the flexible insulating layer 300, thereby ensuring that the projection of the conductive layer 302 onto the flexible insulating layer 300 is located within the flexible insulating layer 300, increasing the creepage distance and electrical gap, and preventing the occurrence of discharge and spark reduction.

[0129] Selectively, the distance from the edge of the conductive layer 302 to the edge of the flexible insulating layer 300 along the width direction of the flexible insulating layer 300 is between 1 mm and 50 mm.

[0130] In this embodiment, the distance from the edge of the conductive layer 302 to the edge of the flexible insulating layer 300 along the width direction of the flexible insulating layer 300 is 1 mm or more and 50 mm or less, which not only ensures an electrical gap but also ensures coverage of the electric field.

[0131] In specific applications, the distance from the edge of the conductive layer 302 to the edge of the flexible insulating layer 300 along the width direction of the flexible insulating layer 300 is one of the following values: 2 mm, 5 mm, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 40 mm, or 50 mm.

[0132] The flexible insulating layer 300 may optionally include an insulating film or an insulating plastic sheet.

[0133] In this embodiment, the flexible insulating layer 300 includes an insulating film or an insulating plastic sheet, which not only enables winding but also ensures an insulating effect between adjacent electrode sheets 30.

[0134] The thickness of the flexible insulating layer 300 can be selected to be between 0.1 mm and 1 mm.

[0135] In this embodiment, the thickness of the flexible insulating layer 300 is between 0.1 mm and 1 mm, ensuring insulation between adjacent electrode sheets 30.

[0136] In specific applications, the thickness of the flexible insulating layer 300 is one of the following values: 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, or 1 mm, or between any two of these values.

[0137] The conductive layer 302 may optionally include a metal foil, a conductive thin film, or a flexible conductive sheet coated with a conductive coating layer.

[0138] In this embodiment, the conductive layer 302 includes one of the following: a metal foil, a conductive thin film, or a flexible conductive sheet coated with a conductive coating layer.

[0139] Selectively, the surface resistance of the conductive layer 302 is 1 × 10⁻⁶. 8 It is less than or equal to Ω.

[0140] In this embodiment, the surface resistance of the conductive layer 302 is 1 × 10⁻⁶ 8 If the impedance is less than or equal to Ω and the electrode sheet 30 is ensured to be longer, then it is ensured that the load voltage does not attenuate significantly.

[0141] As shown in Figure 12, the electrode sheet 30 optionally further includes an electrical connection portion 3020, which is electrically connected to the conductive layer 302 and is used to connect the power supply unit 5.

[0142] In this embodiment, the electrode sheet 30 further includes an electrical connection portion 3020, which is connected to a conductive layer 302 and can be connected to a power supply device 5, thereby supplying high voltage power to the electrode sheet 30, which in turn generates a corresponding electric field and achieves dust adsorption.

[0143] Selectively, along the longitudinal direction of the flexible insulating layer 300, the electrical connection portion 3020 is located at the end of the conductive layer 302.

[0144] In this embodiment, the electrical connection portion 3020 is positioned along the length of the flexible insulating layer 300 at the end of the conductive layer 302 to facilitate connection between the electrical connection portion 3020 and the power supply device 5.

[0145] Please understand that the flexible insulating layer 300 has a strip-like shape.

[0146] The electrical connection portion 3020 may optionally include a metal piece or wiring.

[0147] In this embodiment, the electrical connection portion 3020, which includes metal pieces or wiring, can have a conductive structure.

[0148] In some embodiments, the number of fan blades 2 can be selected to be one or more, and if there are multiple fan blades 2, the multiple fan blades 2 are spaced apart along the rotational axis direction.

[0149] In this embodiment, the number of fan blades 2 is one or more, and if there are multiple fan blades 2, the multiple fan blades 2 are spaced apart along the rotation axis direction, which can provide various air supply modes.

[0150] If the number of fan blades 2 is selectable, the dust collection assembly 3 is positioned between the multiple fan blades 2 and the air intake port 10.

[0151] In some embodiments, the rotation directions of at least two fan blades 2 are selectable to be the same or different.

[0152] In this embodiment, the rotation directions of at least two fan blades 2 are either the same or different. When the rotation directions of at least two fan blades 2 are the same, the distance over which air is supplied can be increased, and when the rotation directions of at least two fan blades 2 are opposite, a windless air supply can be experimented with.

[0153] Selectively, the dust collection assembly 3, ion generator 4, and fan blade 2 are coaxially distributed along the rotation axis direction of the fan blade 2 to improve the purification and dust collection efficiency of the fan.

[0154] Specifically, the present invention relates to the field of air purification, and more specifically to purification and sterilization filters and purification fans, mainly introducing an adaptive flexible electrode filter (e.g., dust collection assembly 3), the filter comprising a positive electrode and a negative electrode, the positive electrode and negative electrode being manufactured from adaptive flexible electrodes, and the filter wound parallel to a helical structure, having the characteristics of low air resistance, high efficiency and simple process. A fan utilizing this helical structure has the effect of dust removal and sterilization.

[0155] Electrostatic dust collection devices (e.g., dust collection assembly 3) have the effect of dust removal and sterilization, and have very low wind resistance, making them suitable for application scenarios with strict requirements regarding wind resistance, such as air conditioners, fans, and heaters. However, since electrostatic dust collection devices mainly rely on an electric field to complete the adsorption and sterilization of granular materials, the electrodes that generate the electric field must be spaced apart, parallel to each other, and connected to the high-voltage output terminal and low-voltage output terminal of the high-voltage power, respectively. Therefore, the current manufacturing process for integrated devices is relatively complex, the manufacturing cost is higher, and the limited form factor restricts the scope of application of the technology. In related technologies, the distance between the positive and negative electrode plates is determined by using external spacing pieces or hot-melt adhesive, which either fails to ensure processing accuracy or requires meticulous manual work, resulting in high processing costs.

[0156] The adaptive flexible electrode filter includes a flexible electrode sheet and a support frame (e.g., frame 32), the flexible electrode sheet being divided into a positive electrode (e.g., positive electrode sheet) and a negative electrode (e.g., negative electrode sheet), which are connected to the high-voltage output terminal and low-voltage output terminal of a high-voltage power supply, respectively, during operation, and both the positive and negative electrodes are flexible electrode sheets equipped with a position-limiting structure (e.g., position-limiting section 301). The positive and negative electrodes are wound parallel to one end of the support frame and engaged with the other end of the support frame to complete the filter assembly. A grid 328 is arranged on the surface of the support frame. The core purification component of a fan utilizing this filter further includes an ion generator 4 and high-voltage power (e.g., power supply 5), and while the fan is operating, the ion generator 4 charges granular matter in the air, the high-voltage power energizes the positive and negative electrodes of the filter, forming an electric field between the positive and negative electrodes, thereby adsorbing the charged granular matter, and the electric field also has a sterilization and disinfection effect.

[0157] The adaptive flexible electrode filter includes a flexible electrode sheet and a support frame with a position-limiting structure.

[0158] A flexible electrode sheet with a position-limiting structure includes a conductive layer 302 and an insulating layer (e.g., a flexible insulating layer 300) with a position-limiting structure, the position-limiting structure being a few protrusions 3011 arranged on the surface of the insulating layer, the support action of which allows the electric field distance between the positive and negative electrodes to be controlled between 0.1 mm and 10 mm.

[0159] A flexible electrode sheet with a position-limiting structure includes a positive electrode with one position-limiting structure and a negative electrode with one position-limiting structure, the positive and negative electrodes being wound parallel to a support frame to form a helical filter body.

[0160] The support frame is made of insulating material, and the flexible electrode sheet is wound along the central axis of the support frame. A grid 328 is placed on the support frame to secure the spirally wound flexible electrode sheet, preventing it from falling off or spreading out from either side, thus maintaining the stability of the filter structure.

[0161] To facilitate winding and packaging, the support frame can be configured as a removable component. First, the flexible electrode sheet is wound around one side of the support frame (e.g., the first frame 320), and then engaged with another assembly (e.g., the second frame 324) to package and secure the filter. The support frame can ensure that the shape of the filter is stable, and can also conceal the wiring to which the positive and negative electrodes are connected to the high-voltage power input terminals, thus ensuring safety during operation.

[0162] When the filter is attached to the fan, it must be used in combination with the ion generator 4 and high-voltage power. By preferentially attaching the filter to the fan's air intake 10, the problem of dust accumulation in the fan body can be effectively mitigated.

[0163] The ion generator 4 can be positioned on the air duct path, preferably near the fan's exhaust port 12 or intake port 10, thereby preventing the generated ions from being blocked by other components in the air duct and affecting the charging effect of the granules.

[0164] The main function of the ion generator 4 is to charge granular material, and it can be a carbon brush positive / negative ion generator, a needle tip positive / negative ion generator, a needle plate charging device, a tungsten wire charging device, etc.

[0165] High-voltage power can be installed in the filter or throughout the entire machine, primarily to supply power to the positive and negative electrodes of the filter.

[0166] The adaptive flexible electrode sheet can be directly wound around a specially shaped filter, controlling the distance between the positive and negative electrodes of the dust collection assembly 3, significantly reducing the technical difficulty and processing cost of the filter, and simultaneously increasing the dust collection area of ​​the filter with the protrusions 3011, thereby improving the dust removal and sterilization effects of the filter.

Terms such as "installation," "connection," "bonding," and "fixing" should be understood in a broad sense; for example, "connection" can be a fixed connection, a detachable connection, or an integrated connection, and "connection" can be a direct connection or an indirect connection through an intermediate medium.
