Description

Technical Field

[0001] The present invention relates to the field of air purification, and in particular to a purification module, a control method, an air purification device, an electrical appliance and an air conditioner. Background Art

[0002] As people's pursuit of healthy life becomes higher and higher, the types of air purification products and related technologies have also developed greatly.

[0003] At present, most air purification products use adsorption materials or catalyst materials as filter components. However, when the saturation of adsorbed and reacted pollutants reaches a critical level, the existing filter components need to be replaced or disassembled for processing, which increases the maintenance cost of the product and reduces the maintenance efficiency. Summary of the invention

[0004] In view of the above problems, the present invention is proposed to provide a purification module, a control method, an air purification device, an electrical appliance and an air conditioner that overcome the above problems or at least partially solve the above problems.

[0005] In a first aspect, a purification module is provided, comprising:

[0006] A purification component, comprising a high-voltage electrode, a low-voltage electrode and a filter component, wherein the high-voltage electrode and the low-voltage electrode are arranged opposite to each other, and the filter component is located between the high-voltage electrode and the low-voltage electrode;

[0007] A driving component is connected to the purification component to drive the high-voltage electrode and the low-voltage electrode to move synchronously relative to the filter component, so that the plasma zone generated between the high-voltage electrode and the low-voltage electrode moves along the surface of the filter component.

[0008] By arranging the filter component between the high-voltage electrode and the low-voltage electrode, the plasma zone generated between the high-voltage electrode and the low-voltage electrode is used to oxidize and decompose the pollutants on the surface of the filter component, so that the filter component is regenerated, and the filter component does not need to be replaced or disassembled, and the pollutants can be filtered and the filter component can be regenerated at the same time, which reduces the maintenance cost of the product and improves the maintenance efficiency. Furthermore, a driving component is also provided to drive the high-voltage electrode and the low-voltage electrode to move synchronously relative to the filter component, so that the size of the electrode does not need to be increased, and the plasma zone is moved along the surface of the filter component through synchronous movement to increase the area of ​​the filter component surface that the plasma zone can act on, avoiding the limitation of the electrode size on the regeneration area of ​​the filter component, and realizing the regeneration of a large-size filter component by a small-size electrode, which can be applied to large air ducts, and further reducing the maintenance cost of the product.

[0009] In some embodiments, the two opposing surfaces of the high-voltage electrode and the low-voltage electrode are adapted to each other. Since the plasma zone is mainly concentrated between the two electrodes, the opposing surfaces of the two electrodes are adapted to each other to ensure that the plasma zone is filled as much as possible between the two electrodes, thereby avoiding wasting excess electrode materials and space.

[0010] In some embodiments, the two opposing surfaces of the high voltage electrode and the low voltage electrode have the same shape and size to ensure that the plasma region is fully distributed between the two electrodes, thereby further avoiding the waste of excess electrode material and space.

[0011] In some embodiments, the relative motion between the high voltage electrode and the low voltage electrode and the filter component is translational motion or rotational motion. By setting different motion modes of the two electrodes relative to the filter component, different product shape requirements can be met, thereby increasing the scope of application.

[0012] In some embodiments, the high-voltage electrode and the low-voltage electrode are both in the shape of a bar. Because when they have the same length, the bar-shaped electrode occupies less space and consumes less electrode material than electrodes of other shapes. And by matching the design of the shape of the filter component and the relative movement direction, the regeneration of the filter component with a larger area can be achieved.

[0013] In some embodiments, the first direction of the length of the high voltage electrode and the low voltage electrode is perpendicular to the second direction, and the second direction is the translational movement direction of the high voltage electrode and the low voltage electrode relative to the filter component. In the case where the type of relative movement is translational movement, by setting the length direction of the electrode to be perpendicular to the direction of relative movement between the electrode and the filter component, a larger plasma zone processing area can be achieved through a smaller movement distance and electrode size.

[0014] Alternatively, the first direction of the length of the high voltage electrode and the low voltage electrode is perpendicular or parallel to the plane of the second direction, and the second direction is the rotational movement direction of the high voltage electrode and the low voltage electrode relative to the filter component. In the case where the type of relative movement is rotational movement, by setting the length direction of the electrode perpendicular or parallel to the plane of the relative movement direction, a larger plasma zone processing area can be achieved through a smaller movement distance and electrode size.

[0015] In some embodiments, both ends of the high voltage electrode exceed or are flush with the edge of the filter component, and both ends of the low voltage electrode exceed or are flush with the edge of the filter component, so as to achieve regeneration of the entire filter component surface through motion energy.

[0016] In some embodiments, the surface of the filter component facing the high-voltage electrode and the surface facing the low-voltage electrode are both positive surfaces, wherein: the positive surface is a rectangle, and the first direction and the second direction are respectively the directions of the two perpendicular sides of the rectangle; or, the positive surface is a circle, and the positive projections of the high-voltage electrode and the low-voltage electrode on the positive surface both cover the center of the circle, and the second direction uses the straight line passing through the center and perpendicular to the positive surface as the rotation axis; or, the positive surface is a cylinder, and the first direction is the direction of the generatrix of the cylinder, and the second direction uses the axis of the cylinder as the rotation axis. By matching the shape of the filter component, the shape of the two electrodes, the position of the two electrodes, and the relative running direction of the electrode and the filter component, the actual needs of different products can be met, and a filter component with a larger area can be regenerated by using a smaller-sized electrode through a shorter distance movement.

[0017] In some embodiments, the surface of the filter component facing the high-voltage electrode and the surface facing the low-voltage electrode are both positive surfaces, wherein: the positive surface is circular; one end of the high-voltage electrode and the low-voltage electrode are both flush with the center of the circle, and the other end of the high-voltage electrode and the low-voltage electrode are both beyond or flush with the edge of the filter component; the second direction uses the straight line passing through the center of the circle and perpendicular to the positive surface as the rotation axis. Further reducing the size of the two electrodes, by increasing the distance of relative movement to achieve regeneration of the entire surface of the filter component, so as to achieve regeneration of a larger area filter component with a smaller size electrode.

[0018] In some embodiments, the high voltage electrode and the low voltage electrode are both annular in shape. For cylindrical or other enclosed filter components, annular electrodes occupy less space and consume less electrode material than electrodes of other shapes.

[0019] In some embodiments, the surface of the filter component facing the high-voltage electrode and the surface facing the low-voltage electrode are both positive surfaces, wherein: the positive surface is cylindrical; the high-voltage electrode and the low-voltage electrode are sleeved and located in a plane perpendicular to the busbar of the cylinder; the second direction of movement of the high-voltage electrode and the low-voltage electrode relative to the filter component is the direction of the busbar of the cylinder. By matching the shape of the filter component, the shape of the two electrodes, the position of the two electrodes, and the relative running direction of the electrodes and the filter component, the regeneration of the filter component with a larger area by a smaller-sized electrode through a shorter-distance movement is achieved.

[0020] In some embodiments, the purification module further comprises: a dielectric layer located between the high voltage electrode and the low voltage electrode; wherein the dielectric layer is disposed on the high voltage electrode and / or the low voltage electrode. The provision of the dielectric layer improves the safety of the electrodes and the uniformity of the plasma zone.

[0021] In some embodiments, the driving assembly is connected to both the high voltage electrode and the low voltage electrode to drive the high voltage electrode and the low voltage electrode to move; or the driving assembly is connected to the filter component to drive the filter component to move. By flexibly setting the connection mode between the driving assembly and the purification assembly, a variety of relative movement modes are provided to meet the needs of more types of products.

[0022] In a second aspect, a control method for a purification module is provided, wherein the purification module comprises a connected purification component and a driving component, wherein the purification component comprises a high-voltage electrode, a low-voltage electrode and a filter component; the high-voltage electrode and the low-voltage electrode are arranged opposite to each other, and the filter component is located between the high-voltage electrode and the low-voltage electrode; the control method comprises: powering on the high-voltage electrode and the low-voltage electrode to generate a plasma zone between the high-voltage electrode and the low-voltage electrode; controlling the driving component to output a driving force to drive the high-voltage electrode and the low-voltage electrode to move synchronously relative to the filter component, so that the plasma zone moves along the surface of the filter component, thereby regenerating the filter component.

[0023] The plasma zone is moved along the surface of the filter component by synchronous motion, so that the surface area of ​​the filter component that can be acted upon by the plasma zone can be increased without increasing the size of the electrode, thereby avoiding the limitation of the electrode size on the regeneration area of ​​the filter component and saving maintenance costs.

[0024] In some embodiments, the step of powering on the high-voltage electrode and the low-voltage electrode includes: obtaining a regeneration signal, the regeneration signal being a signal indicating that the pollutant saturation of the filter component has reached a preset saturation; and powering on the high-voltage electrode and the low-voltage electrode based on the regeneration signal. By setting a preset saturation to trigger the regeneration process, the regeneration function does not need to be turned on all the time, thereby achieving an energy-saving effect.

[0025] In a third aspect, an air purification device is provided, comprising any purification module described in the first aspect, thereby reducing the maintenance cost of the product and improving the maintenance efficiency.

[0026] In a fourth aspect, an electrical appliance is provided, comprising the air purification device described in the third aspect, thereby reducing the maintenance cost of the product and improving the maintenance efficiency.

[0027] In a fifth aspect, an air conditioner is provided, comprising the air purification device described in the third aspect, thereby reducing the maintenance cost of the product and improving the maintenance efficiency.

[0046] The present invention is described below with reference to specific embodiments in conjunction with the accompanying drawings.

[0047] First, combine Figure 1-11 A purification module 100 provided in an embodiment of the present invention is described, comprising:

[0048] The purification component 110 includes a high-voltage electrode 111, a low-voltage electrode 112, and a filter component 113. The high-voltage electrode 111 and the low-voltage electrode 112 are arranged opposite to each other, and the filter component 113 is arranged between the high-voltage electrode 111 and the low-voltage electrode 112.

[0049] The driving component 120 is connected to the purification component 110 to drive the high-voltage electrode 111 and the low-voltage electrode 112 to move synchronously relative to the filter component 113, so that the plasma zone generated between the high-voltage electrode 111 and the low-voltage electrode 112 can move along the surface of the filter component 113 to regenerate the filter component 113.

[0050] The high voltage electrode 111 and the low voltage electrode 112 move synchronously relative to the filter component 113 , including simultaneous movement and movement in the same direction.

[0051] Specifically, when the high-voltage electrode 111 and the low-voltage electrode 112 are powered on, a plasma zone with plasma is generated between the two electrodes, and the plasma zone acts on the filter component 113, oxidizing pollutants such as organic matter and viruses and bacteria on the surface of the filter component 113 into water and carbon dioxide, thereby reducing the saturation of pollutants on the filter component 113, increasing the surface activity of the filter component 113, and realizing the regeneration of the filter component 113 without disassembling the filter component 113. In addition, the two electrodes are driven to move synchronously relative to the filter component 113 through the driving component 120, thereby driving the plasma zone to move along the surface of the filter component 113, increasing the area that the plasma zone can act on, and effectively avoiding the limitation of the electrode size on the regeneration area of ​​the filter component 113.

[0052] It should be noted that the purification module 100 provided by the present invention can be a gas purification module for filtering air or exhaust gas, or a purification module for filtering non-conductive liquids or non-conductive aerosols, and is not limited here.

[0053] The purification component 110 is first introduced.

[0054] The filter element 113 in the purification assembly 110 has a filtering and purification function, and its shape can be as follows: Figure 1-4 and Figure 6-9 As shown, it is a rectangular parallelepiped, cylindrical or tubular shape, etc., and the distribution structure of the filter material inside it can be a mesh, honeycomb or granular structure to facilitate gas flow.

[0055] The filter material in the filter component 113 can be an active material, an adsorption material such as a molecular sieve, or a catalyst of a metal oxide-based porous material, for example, a catalyst prepared using one or more of molecular sieves, activated alumina, cerium oxide, MnO2-based materials and CrO2-based materials, without limitation herein.

[0056] The high voltage electrode 111 and the low voltage electrode 112 in the purification component 110 are arranged opposite to each other. Figure 1 and Figure 5 As shown, the high voltage electrode 111 is connected to the high voltage power supply 130, and the low voltage electrode 112 is connected to the ground or other relatively low voltage terminals. After the high voltage electrode 111 is powered on, a voltage difference is generated between the high voltage electrode 111 and the low voltage electrode 112, thereby generating a plasma region ( Figure 1 , Figure 3 and Figure 5 The area indicated by the dashed line).

[0057] The materials of the two electrodes can be conductors such as copper, tungsten, and iron, and the shapes of the two electrodes can be strips, rings, plates, meshes, or lines, etc., which are not limited here.

[0058] In some embodiments, two opposing surfaces of the high voltage electrode 111 and the low voltage electrode 112 may be configured to match. Matching may mean having the same or similar shapes and having the same or similar sizes.

[0059] Among them, similar shapes include: right-angled rectangle and rounded rectangle, right-angled bar and rounded bar, toothed edge shape and wavy edge shape, circular ring and elliptical ring, circular ring and square ring, mesh type and hole type, etc.

[0060] Among them, the close size can be that the difference in the electrode sizes of the high-voltage electrode 111 and the low-voltage electrode 112 in the same direction is set to meet a preset range. For example, the ratio of the difference in the electrode sizes in this direction to the sizes of each electrode in this direction is set to be less than or equal to a preset percentage. The preset percentage can be set in the range of 10% to 30%. Of course, it can also be set in the range of greater than 30% or less than 10%.

[0061] Because the plasma zone is mainly concentrated between the two electrodes, the surfaces of the two electrodes facing each other are matched to ensure that the plasma zone is as full as possible between the two electrodes, thus avoiding wasting excess electrode material and space.

[0062] In some embodiments, the sizes and shapes of the two opposing surfaces of the high voltage electrode 111 and the low voltage electrode 112 may be the same to ensure that the plasma region is fully distributed between the two electrodes, further avoiding the waste of excess electrode material and space.

[0063] Among them, a dielectric layer 114 can also be arranged between the high-voltage electrode 111 and the low-voltage electrode 112 to increase the uniformity and discharge safety of the generated plasma zone. Of course, the dielectric layer 114 can also be omitted, and the plasma zone can be generated directly by electrode discharge, which is not limited here.

[0064] The dielectric layer 114 may be Figure 1 As shown, the dielectric layer 114 is disposed on the high voltage electrode 111 to increase the discharge safety of the high voltage electrode 111. Of course, the dielectric layer 114 can also be disposed on the low voltage electrode 112, or as shown in FIG. Figure 5 The dielectric layer 114 is disposed on both electrodes, which is not limited here. The dielectric layer 114 can be an insulating material such as quartz, ceramic or silica gel, and the dielectric layer 114 can be disposed on the electrode by plating, sleeve, pasting or coating, which is not limited here.

[0065] The drive assembly 120 is then introduced.

[0066] The driving component 120 is connected to the purification component 110 to provide a driving force for relative movement of two electrodes or filter components 113 in the purification component 110 .

[0067] Specifically, you can Figure 1 As shown, the driving assembly 120 is connected to the filter component 113, and the relative movement between the electrode and the filter component 113 is achieved by driving the filter component 113 to move; Figure 6 As shown, the driving assembly 120 is connected to the two electrodes, and the relative movement between the electrodes and the filter component 113 is achieved by driving the two electrodes to move. Specifically, the above two driving modes can be flexibly selected in combination with the scenario in which the purification module 100 is used to enrich its applicability.

[0068] The driving assembly 120 may include a power component such as a motor or a cylinder that can output a driving force, and may also include a connecting component such as a rotating shaft or a connecting rod that transmits the driving force to the purification assembly 110. The power component is connected to the purification assembly 110 through the connecting component.

[0069] For example, Fig.10 As shown, the driving assembly 120 may be a cylinder, including a cylinder body 121, a piston 122 and a connecting rod mechanism 123. The fixed end 1231 of the connecting rod mechanism 123 is fixed to the middle of the filter component 113, and the movable end 1232 of the connecting rod mechanism 123 is fixed to the edge of the filter component 113. Fig.10 The dashed arrows shown control the inflow and outflow of air, and can control the piston 122 to drive the connecting rod mechanism 123 to move, so that the movable end 1232 rotates around the fixed end 1231, thereby providing a driving force for the filter component 113 to rotate. Of course, the fixed end 1231 of the connecting rod mechanism 123 can also be fixed at the middle of the two electrodes, and the movable end 1232 of the connecting rod mechanism 123 can be fixed at the edge of the two electrodes, thereby providing a driving force for the electrodes to rotate.

[0070] Of course, if the relative motion between the two electrodes and the filter component 113 is translation, Fig.10The connecting rod mechanism 123 in the embodiment is replaced with a straight rod, one end of which is connected to the piston 122, and the other end is connected to the filter component 113 or two electrodes. Fig.10 The dashed arrows shown control the inflow and outflow of air, and can control the piston 122 to drive the straight rod to move, thereby providing a translational driving force for the filter component 113 or the two electrodes.

[0071] For example, Fig.11 As shown, the driving assembly 120 can be a motor, including a motor body 124 and a rotating shaft 125. The output end of the rotating shaft 125 is connected to the middle of the filter component 113. When the motor is running, the rotating shaft 125 rotates, thereby driving the filter component 113 to rotate, providing a driving force for the filter component 113 to rotate. Of course, the output end of the rotating shaft 125 of the motor can also be fixed in the middle of the two electrodes, thereby providing a driving force for the electrodes to rotate.

[0072] Next, the arrangement of the electrodes, the filter component 113 and the drive assembly 120 will be described.

[0073] In a specific implementation process, two electrodes (ie, the high voltage electrode 111 and the low voltage electrode 112 ) and the filter component 113 may be arranged in parallel and spaced apart to obtain a stable and uniform plasma region.

[0074] The relative movement between the high voltage electrode 111 and the low voltage electrode 112 and the filter component 113 can be set to be a translational movement or a rotational movement to adapt to the shape requirements of different filter components 113 and increase the applicable scenarios.

[0075] The shapes and positions of the two electrodes and the filter component 113 and the relative movement direction driven by the driving assembly 120 can be matched to optimize the avoidance of the restriction of the electrode size on the regeneration area of ​​the filter component, and to achieve the regeneration of the large-sized filter component by the smaller-sized electrode. There are many ways to match and set the specific configuration, and examples are given below to illustrate:

[0076] For example, the high voltage electrode 111 and the low voltage electrode 112 may both be in the shape of bars.

[0077] In the case of the same length, the strip electrode occupies less space than other shapes of electrodes and consumes less electrode material. And by matching the design of the shape and relative movement direction of the filter component 113, the regeneration of the filter component 113 with a larger area can be achieved. It should be noted that the strip in this example can be a strip with a regular shape and uniform size, or a strip with an irregular shape or uneven size (for example, a strip with a curved edge or a strip with varying thickness).

[0078] In some embodiments, the positions of the high voltage electrode 111 and the low voltage electrode 112 relative to the filter component 113 can be set, and the length direction of the two strip electrodes is set to be the direction in which they have the largest size, and the first direction a of the length is perpendicular to the second direction b (such as Figure 6 ), the second direction b is the translational movement direction of the high voltage electrode 111 and the low voltage electrode 112 relative to the filter component 113.

[0079] When the relative movement between the two electrodes and the filter component 113 is a translational movement, by setting the first direction a of the electrode length and the second direction b of the relative movement perpendicular, a larger plasma zone processing area can be achieved through a smaller movement distance and electrode size.

[0080] In some embodiments, it is also possible to set the first direction a of the lengths of the high voltage electrode 111 and the low voltage electrode 112 to be perpendicular to the plane where the second direction b is located (eg Figure 7 ), or the first direction a is parallel to the plane where the second direction b is located (such as Figure 2 ), wherein the rotational movement direction of the high voltage electrode 111 and the low voltage electrode 112 relative to the filter component 113 is the second direction b.

[0081] When the relative motion between the two electrodes and the filter component 113 is rotational motion, by setting the length direction of the electrode to be perpendicular or parallel to the plane where the direction of relative motion lies, a larger plasma zone processing area can be achieved through a smaller movement distance and electrode size.

[0082] In some embodiments, both ends of the high voltage electrode 111 and the low voltage electrode 112 may be arranged to exceed or be flush with the edge of the filter component 113. That is, the orthographic projections of the two electrodes on the front surface both penetrate the front surface. By arranging both ends of the electrodes to exceed or be flush with the edge of the filter component 113, plasma regeneration of the entire surface of the filter component 113 can be achieved through relative movement.

[0083] Here are a few examples:

[0084] like Figure 1-4 As shown, Figure 1 The structure of the purification module in the embodiment of the present invention is Figure 1 , Figure 2 for Figure 1 A top view of the purification components. Figure 3 for Figure 1 Side view of the purification component. Figure 4 for Figure 1In the bottom view of the purification component, the filter component 113 is a cylinder or a circular plate, that is, the circular surface facing the high-voltage electrode 111 and the circular surface facing the low-voltage electrode 112 on the filter component 113 are two positive surfaces. Among them, the positive projections of the two electrodes on the two positive surfaces facing each other cover the center of the circle, that is, the two electrodes are arranged along the diameter of the circle. The second direction b in which the two electrodes and the filter component 113 produce relative motion is: the rotation direction with the straight line passing through the center of the circle and perpendicular to the positive surface as the rotation axis. The first direction a where the length of the two strip electrodes is located is parallel to the plane where the second direction b is located.

[0085] With this arrangement, the entire filter component 113 can be regenerated by controlling the two strip electrodes and the filter component 113 to rotate 180 degrees relative to each other in the second direction b. The larger filter component 113 can be fully regenerated by using electrodes of smaller size to perform relative movement of smaller distance. The purification module 100 does not need to stop running, and the entire filter surface of the filter component 113 is still in the filtering working state to complete the regeneration. This improves the product maintenance efficiency and saves maintenance costs.

[0086] like Figure 6 As shown, Figure 6 The structure of the purification module in the embodiment of the present invention is Figure 2 , the filter component 113 is a cuboid or a rectangular plate, that is, the two front surfaces of the filter component 113 facing the high voltage electrode 111 and the low voltage electrode 112 are rectangular. Among them, the second direction b of the relative movement between the two electrodes and the filter component 113, and the first direction a where the lengths of the two electrodes are located, are respectively the directions of the two sides of the rectangle that are perpendicular to each other.

[0087] In this way, it is only necessary to control the two strip electrodes to move the distance of one side of the rectangle relative to the filter component 113 along the second direction b to achieve the regeneration of the entire filter component 113. The limitation of the electrode size on the regeneration area of ​​the filter component 113 is also overcome, and the pollutant filtering and the filter component regeneration can be performed at the same time, which reduces the maintenance cost of the product and improves the maintenance efficiency.

[0088] like Figure 7 As shown ( Figure 7 The structure of the purification module in the embodiment of the present invention is Figure 3 ), the filter component 113 is cylindrical, that is, the two front surfaces of the filter component 113 facing the high voltage electrode 111 and the low voltage electrode 112 are cylindrical. Among them, the first direction a where the lengths of the two electrodes are located is the direction where the busbars of the cylinder are located. The second direction b where the two electrodes and the filter component 113 move relative to each other is the rotation direction with the axis of the cylinder as the rotation axis.

[0089] In this way, it is only necessary to control the two strip electrodes and the filter component 113 to rotate 360 ​​degrees relative to each other along the second direction b to achieve regeneration of the entire filter component 113. The limitation of the electrode size on the regeneration area of ​​the filter component 113 is also overcome, and the filter component can be regenerated while filtering pollutants, thereby reducing the maintenance cost of the product and improving the maintenance efficiency.

[0090] In some embodiments, the size of the two electrodes may be further reduced to achieve regeneration of the entire surface of the filter element 113 by increasing the distance of relative movement.

[0091] For example, Figure 8 As shown ( Figure 8 The structure of the purification module in the embodiment of the present invention is Figure 4 ), the filter component 113 is a cylinder (or a circular plate), that is, the two front surfaces of the filter component 113 facing the high-voltage electrode 111 and the low-voltage electrode 112 are circular. Among them, one end of the high-voltage electrode 111 and the low-voltage electrode 112 are both flush with the center of the circle, and the other ends of the high-voltage electrode 111 and the low-voltage electrode 112 are both beyond or flush with the edge of the filter component 113, that is, the two electrodes are arranged along the radius of the circle. The second direction b of the relative movement of the two electrodes and the filter component 113 is: the rotation direction with the straight line passing through the center of the circle and perpendicular to the front surface as the rotation axis.

[0092] So relative to Figure 1 The purification module shown, Figure 8 The purification module shown further reduces the size of the two electrodes. It only needs to increase the distance of controlling the relative movement of the two strip electrodes and the filter component 113, that is, to rotate 360 ​​degrees relative to each other in the second direction b, to achieve regeneration of the entire filter component 113, further saving costs.

[0093] Of course, in addition to reducing the size of the electrode by increasing the relative movement distance between the electrode and the filter component 113, you can also reduce the relative movement distance between the electrode and the filter component 113 by increasing the size or number of the electrode. This is not limited here and will not be listed one by one.

[0094] For another example, the high voltage electrode 111 and the low voltage electrode 112 may both be ring-shaped.

[0095] For the cylindrical or other enclosed filter components 113, the annular electrode occupies less space and consumes less electrode material than electrodes of other shapes. Moreover, by matching and designing the shape and relative movement direction of the filter component 113, the regeneration of the filter component 113 with a larger area can be achieved. The annular shape can be a circular ring, a square ring, an elliptical ring, etc.

[0096] For example, Fig. 9 As shown ( Fig. 9 The structure of the purification module in the embodiment of the present invention is Figure 5 ), the filter component 113 is cylindrical, that is, the two front surfaces of the filter component 113 facing the high-voltage electrode 111 and the low-voltage electrode 112 are cylindrical. Both electrodes are annular. Among them, the high-voltage electrode 111, the filter component 113 and the low-voltage electrode 112 are arranged in sequence, and the two electrodes are located in a plane perpendicular to the busbar of the cylinder. The second direction b of the relative movement of the two electrodes and the filter component 113 is the direction of the busbar of the cylinder.

[0097] In this way, it is only necessary to control the two annular electrodes and the filter component 113 to move relative to each other along the second direction b by a distance of the cylinder height to achieve regeneration of the entire filter component 113. This also overcomes the limitation of the electrode size on the regeneration area of ​​the filter component 113, and there is no need to stop filtering pollutants when regenerating the filter component, thereby reducing maintenance costs and improving maintenance efficiency.

[0098] Of course, the specific shape of the filter component 113 is not limited to the above examples, and can also be a polygon, a ring or a sphere, etc.; the shapes of the two electrodes are not limited to bars and rings, but can also be circles, arcs or broken lines, etc., which are not limited here and will not be listed one by one.

[0099] Of course, in the specific implementation process, the number of filter components 113 is not limited to one, and there can be multiple. The number of electrodes is not limited to two, and there can be multiple pairs, or one high-voltage electrode 111 is provided with multiple low-voltage electrodes 112, which are not limited here.

[0100] Next, combine Fig.12 The control method of the purification module 100 provided in the embodiment of the present invention includes:

[0101] Step S1201, powering up the high voltage electrode 111 and the low voltage electrode 112 to generate a plasma region between the high voltage electrode 111 and the low voltage electrode 112;

[0102] Step S1202 , controlling the driving assembly 120 to output a driving force to drive the high voltage electrode 111 and the low voltage electrode 112 to move synchronously relative to the filter component 113 , so that the plasma zone moves along the surface of the filter component 113 , thereby regenerating the filter component 113 .

[0103] It should be noted that there is no restriction on the execution order of step S1201 and step S1202. Step S1201 may be executed first, or step S1202 may be executed first, or both steps may be executed simultaneously.

[0104] It should also be noted that in step S1201, when the two electrodes are powered on, the low-voltage electrode 112 can be grounded and the high-voltage electrode 111 can be connected to a high-voltage power supply, or the low-voltage electrode 112 can be not directly grounded but connected to a relatively low-voltage end and the high-voltage electrode 111 can be connected to a high-voltage power supply.

[0105] In some embodiments, it can be set that when the purification module 100 is in the purification state, the two electrodes are not powered on and do not produce relative movement. After obtaining a regeneration signal indicating that the pollutant saturation of the filter component 113 has reached a preset saturation, the high-voltage electrode 111 and the low-voltage electrode 112 are powered on based on the regeneration signal, and the drive component 120 is controlled to output a driving force to drive the two electrodes to move synchronously relative to the filter component 113. This can achieve the regeneration of the filter component 113 while purifying, and trigger the regeneration process by setting a preset saturation, thereby achieving an energy-saving effect.

[0106] In some embodiments, a sensor may be provided on the filter component 113 to monitor the pollutant saturation. After reaching a preset saturation, the sensor sends a regeneration signal to the controller, and the controller controls the power supply to power on the electrode and controls the drive component 120 to output the driving force. Alternatively, the sensor may send the pollutant saturation to the controller in real time or at a fixed time. After determining that the pollutant saturation reaches the preset saturation, the controller generates a regeneration signal, controls the power supply to power on the electrode, and controls the drive component 120 to output the driving force. The controller may be provided in the purification module 100 or may be provided externally to the purification module 100.

[0107] In some embodiments, when the purification module 100 is in the purification state, the two electrodes are kept in the power-on state, and the driving component 120 is kept outputting the driving force to drive the two electrodes to move synchronously relative to the filter component 113. In this way, the filter component 113 is continuously regenerated during purification, the purification effect is better, and it is more suitable for the case of high-concentration pollutants.
