[0037] Please refer to Figure 1 In an embodiment, the electrostatic dust removal mechanism includes a support 100, a dust collecting electrode 200, a cleaning piece 300, and a controller. The dust collecting electrode 200 is rotatably arranged on the support 100 and used for dust collection. The cleaning piece 300 is movably arranged on the outer periphery of the dust collecting electrode 200 and used for cleaning the dust collecting electrode 200. The controller is electrically connected with the cleaning piece 300 and the dust collecting electrode 200, respectively.

[0038] When the electrostatic dust removal mechanism is in the first cleaning mode, the controller drives the dust collecting electrode 200 to rotate; when the electrostatic dust removal mechanism is in the second cleaning mode, the controller drives the cleaning piece 300 to move; and when the electrostatic dust removal mechanism is in the dust collecting mode, the controller controls the dust collecting electrode 200 and the cleaning piece 300 to be fixed.

[0039] It should be noted that the electrostatic dust removal mechanism will accumulate a certain amount of particulate matter and dust on the dust collecting electrode 200 after being used for a period of time. If the dust collecting electrode 200 is not cleaned in time, the deflection ability of the repulsion electric field will be affected, thereby reducing the air purification efficiency. When the electrostatic dust removal mechanism is in the first cleaning mode, the controller drives the dust collecting electrode 200 to rotate, and at this time the cleaning piece 300 is fixed; when the electrostatic dust removal mechanism is in the second cleaning mode, the controller drives the cleaning piece 300 to move, and at this time the dust collecting electrode 200 is fixed.

[0040] The electrostatic dust removal mechanism described above can drive the dust collecting electrode 200 to rotate in the first cleaning mode to remove floating dust on the surface of the dust collecting electrode 200, and can drive the cleaning piece 300 to move along the dust collecting electrode 200 in the second cleaning mode to deeply remove floating dust and pollutants on the surface of the dust collecting electrode 200 through strong friction. Users can select different cleaning modes to clean the dust collecting electrode 200 according to actual needs, thereby achieving better cleaning effect and meeting the diversified cleaning needs of users.

[0041] In the above embodiment, the support 100 can be a one-piece structure or a split structure. The support 100 can be square, circular or other shapes, and the specific structure and shape of the support 100 are not specifically limited here.

[0042] In the above embodiment, the cleaning piece 300 is made of high-hardness wear-resistant material, such as silicon carbide or high manganese steel, and has good cleaning effect and is not easy to wear when cleaning the dust collecting electrode 200.

[0043] Further, please refer to Figure 1 The electrostatic dust removal mechanism further includes a first detection piece electrically connected with the controller and used for detecting the dust collecting quality of the dust collecting electrode 200. The controller controls the electrostatic dust removal mechanism to switch to one of the first cleaning mode, the second cleaning mode and the dust collecting mode according to the dust collecting quality of the dust collecting electrode 200. In this way, whether the dust collecting electrode 200 needs to be cleaned can be determined according to the dust collecting quality of the dust collecting electrode 200, which facilitates users to quickly and timely clean the dust collecting electrode 200.

[0044] For example, when the dust collection quality of the dust collection pole 200 is less than the first threshold value, the dust collection pole 200 can still be used, the controller controls the electrostatic dust removal mechanism to be in the dust collection mode, and the dust collection pole 200 and the cleaning piece 300 are fixed; when the dust collection quality of the dust collection pole 200 is greater than or equal to the first threshold value and less than or equal to the second threshold value, the dust collection pole 200 needs to be cleaned, the controller controls the electrostatic dust removal mechanism to be in the first cleaning mode, and drives the dust collection pole 200 to rotate to remove floating dust on the surface of the dust collection pole 200; when the dust collection quality of the dust collection pole 200 is greater than the second threshold value, the dust collection pole 200 needs to be deeply cleaned, the controller controls the electrostatic dust removal mechanism to be in the second cleaning mode, and drives the cleaning piece 300 to move to deeply remove floating dust and pollutants on the surface of the dust collection pole 200.

[0045] In the embodiment, the number of the first detection pieces is not limited to one, that is, at least two first detection pieces can be arranged on each dust collection pole 200, and all the first detection pieces can be arranged at different positions of the dust collection pole 200, so that the dust accumulation degree of the dust collection pole 200 at different positions is obtained, and the detection accuracy of the dust collection quality is improved.

[0046] In the embodiment, the first detection piece is a single-function sensor for detecting only the quality. In other embodiments, the first detection piece can also be a multi-function sensor for detecting the quality, humidity and other parameters.

[0047] Please refer to Figure 1 The electrostatic dust removal mechanism further comprises a driving piece, which is connected with the dust collection pole 200 and used to drive the dust collection pole 200 to rotate.

[0048] It should be noted that the driving piece is electrically connected with the controller. When the electrostatic dust removal mechanism is in the first cleaning mode, the controller drives the driving piece to operate, and the driving piece drives the dust collection pole 200 to rotate around the axis of the dust collection pole 200, so as to remove the floating dust on the surface of the dust collection pole 200.

[0049] In the embodiment, the driving piece is a motor, the output shaft of the motor is connected with the dust collection pole 200, and the motor can be a stepping motor or other types of driving motor, and the type of the motor is not limited here. In other embodiments, the driving piece can also be other types of driving structures that can drive the dust collection pole 200 to rotate.

[0050] Please refer to Figure 1 and Figure 2 Both ends of the dust collection pole 200 are respectively provided with a magnetic flux coil 400, and the cleaning piece 300 has magnetism; all the magnetic flux coils 400 generate a magnetic field in the energized state, and the cleaning piece 300 can reciprocate along the dust collection pole 200 under the action of the magnetic field.

[0051] It can be understood that the magnetic flux coil 400 generates a magnetic field in the energized state, and by controlling the frequency difference of the low-voltage power supply of the magnetic flux coil 400 at both ends of the dust collecting pole 200, the direction of the magnetic field is changed constantly, so that the cleaning piece 300 moves back and forth along the dust collecting pole 200. The magnetic flux coil 400 at both ends of the dust collecting pole 200 does not generate a magnetic field in the de-energized state, at which time the cleaning piece 300 is stationary and magnetically attracted to the magnetic flux coil 400.

[0052] In the embodiment, one magnetic flux coil 400 is arranged at each end of the dust collecting pole 200. In other embodiments, at least two magnetic flux coils 400 can also be arranged at each end of the dust collecting pole 200.

[0053] In the embodiment, the magnetic flux coil 400 is sleeved on the end of the dust collecting pole 200, so that the magnetic flux coil 400 is preliminarily fixed. In other embodiments, the magnetic flux coil 400 can also be adhered to the end of the dust collecting pole 200 by glue.

[0054] Please refer to Figure 1 The bracket 100 includes two first fixing plates 110 arranged at intervals along the first direction, and the dust collecting pole 200 is rotatably arranged between the two first fixing plates 110. Each first fixing plate 110 is provided with a receiving groove for accommodating the magnetic flux coil 400.

[0055] Here, the first direction is the X direction shown in Figure 1 , that is, the axis direction of the dust collecting pole 200. The dust collecting pole 200 is rotatably arranged between the two first fixing plates 110, and each first fixing plate 110 is provided with a receiving groove for accommodating the magnetic flux coil 400. The end of the dust collecting pole 200 penetrates the magnetic flux coil 400 and is located in the receiving groove. Through this arrangement, the space utilization of the first fixing plate 110 can be effectively improved.

[0056] In the embodiment, the two first fixing plates 110 are arranged at intervals along the first direction, and the shapes and sizes of the two first fixing plates 110 are completely the same, so as to facilitate installation and processing; for example Figure 1 As shown in the figure, both of the first fixing plates 110 are in the shape of a cuboid plate. In other embodiments, the shapes and sizes of the two first fixing plates 110 can also be different, for example, one of the two first fixing plates 110 is in the shape of a cuboid plate, and the other is in the shape of a cylinder or other shapes.

[0057] In the embodiment, the receiving groove can be circular, square or other shapes, and the shape of the receiving groove is not specifically limited here.

[0058] Please refer to Figure 1The electrostatic dust removal mechanism further comprises a discharge electrode 500 disposed between the two first fixed plates 110. When the electrostatic dust removal mechanism is in the dust collection mode, the discharge electrode 500 generates an electrostatic field in the energized state, and the dust collection electrode 200 collects dust under the action of the electrostatic field.

[0059] It should be noted that the discharge electrode 500 is connected with an external high-voltage power supply. When the electrostatic dust removal mechanism is in the dust collection mode, an electrostatic field is generated between the discharge electrode 500 and the dust collection electrode 200 in the energized state, and the charged particulate pollutants are adsorbed on the dust collection electrode 200 under the action of the electrostatic field, thereby realizing air purification.

[0060] Specifically, the discharge electrode 500 is a metal wire. Preferably, the discharge electrode 500 is a tungsten wire.

[0061] In the embodiment, the first fixed plate 110 is provided with a fixing hole, and the end of the discharge electrode 500 is disposed through the fixing hole and fixed in the fixing hole. In other embodiments, the discharge electrode 500 can also be welded or riveted to the first fixed plate 110.

[0062] Please refer to Figure 1 a plurality of discharge electrodes 500 and a plurality of dust collection electrodes 200 are alternately arranged along a second direction perpendicular to the first direction, and at least one cleaning piece 300 is sleeved on each dust collection electrode 200.

[0063] Here, the second direction is Figure 1 the Y direction shown in the figure, that is, the radial direction of the dust collection electrode 200. By alternately arranging a plurality of discharge electrodes 500 and a plurality of dust collection electrodes 200 along the second direction perpendicular to the first direction, the air purification efficiency can be improved and the space utilization of the first fixed plate 110 can be improved.

[0064] In the embodiment, one cleaning piece 300 is sleeved on each dust collection electrode 200. In other embodiments, at least two cleaning pieces 300 can be sleeved on each dust collection electrode 200 to clean different positions of the dust collection electrode 200 and strengthen the cleaning effect.

[0065] Further, please refer to Figure 1 The bracket 100 further comprises two second fixed plates 120 spaced apart along the second direction, the second fixed plates 120 are connected with the first fixed plates 110, and all the discharge electrodes 500 and the dust collection electrodes 200 are disposed between the two second fixed plates 120. In this way, the discharge electrodes 500 and the dust collection electrodes 200 can be effectively prevented from being exposed in the second direction, thereby avoiding safety hazards.

[0066] In the embodiment, the two second fixing plates 120 are connected with the two first fixing plates 110 and surround the hollow bracket 100 in a rectangular shape. The second fixing plate 120 and the first fixing plate 110 can be an integrated structure, for example, integrally formed by injection molding. Alternatively, the second fixing plate 120 and the first fixing plate 110 are a split structure, for example, fixed by welding or riveting.

[0067] Please refer to Figure 2 The cleaning piece 300 is annular, the dust collecting pole 200 is columnar, and the outer diameter of the dust collecting pole 200 is equal to the inner diameter of the cleaning piece 300.

[0068] Here, the outer diameter of the dust collecting pole 200 is equal to the inner diameter of the cleaning piece 300, that is, the outer wall of the dust collecting pole 200 can tightly abut the inner wall of the cleaning piece 300. When the cleaning piece 300 can reciprocate along the dust collecting pole 200 under the action of the magnetic field, the surface cleaning effect of the dust collecting pole 200 is better.

[0069] In the embodiment, the dust collecting pole 200 is cylindrical, and correspondingly, the cleaning piece 300 is annular to match the dust collecting pole 200. In other embodiments, the dust collecting pole 200 can also be prismatic or other shapes, and correspondingly, the cleaning piece 300 can also be square ring or other shapes.

[0070] Please refer to Figure 1 The electrostatic dust removal mechanism further comprises a second detection piece, which is electrically connected with the controller and is used for detecting the moving position of the cleaning piece 300.

[0071] It can be understood that when the electrostatic dust removal mechanism is in the first cleaning mode, the controller drives the dust collecting pole 200 to rotate and the cleaning piece 300 to be fixed; when the electrostatic dust removal mechanism is in the second cleaning mode, the controller drives the cleaning piece 300 to move and the dust collecting pole 200 to be fixed; and when the electrostatic dust removal mechanism is in the dust collecting mode, the controller controls the dust collecting pole 200 and the cleaning piece 300 to be fixed. By setting the second detection piece, the position of the cleaning piece 300 can be monitored in real time, so that the movement of the cleaning piece 300 can be better controlled.

[0072] For example, when the electrostatic dust removal mechanism is in the second cleaning mode, the cleaning piece 300 reciprocates along the dust collecting pole 200 under the action of the magnetic field to deeply remove the dust and pollutants on the surface of the dust collecting pole 200 by strong friction. In order to make the dust collecting pole 200 have no cleaning dead angle, the cleaning piece 300 is preferably moved to the limit position at both ends of the dust collecting pole 200 each time, and the controller can control the cleaning piece 300 to move to the limit position at both ends of the dust collecting pole 200 each time through the second detection piece, so that the cleaning effect is better.

[0073] In the embodiment, the second detection member is a single-function sensor for position detection only. In other embodiments, the second detection member can also be a multi-function sensor for position detection, humidity detection, and the like.

[0074] In the embodiment, the number of the second detection members is not limited to one, i.e., at least two second detection members can be provided on each cleaning member 300. All the second detection members can be arranged at different positions of the cleaning member 300, so as to improve the detection accuracy of the position of the cleaning member 300.

[0075] Please refer to Figure 1 The control method of the electrostatic dust removal mechanism in an embodiment includes:

[0076] detecting the dust collection quality of the dust collection electrode 200;

[0077] when the dust collection quality of the dust collection electrode 200 is less than a first threshold value, controlling the electrostatic dust removal mechanism to be in a dust collection mode, and controlling the dust collection electrode 200 and the cleaning member 300 to be stationary;

[0078] when the dust collection quality of the dust collection electrode 200 is greater than or equal to the first threshold value and less than or equal to a second threshold value, controlling the electrostatic dust removal mechanism to be in a first cleaning mode, and driving the dust collection electrode 200 to rotate;

[0079] when the dust collection quality of the dust collection electrode 200 is greater than the second threshold value, controlling the electrostatic dust removal mechanism to be in a second cleaning mode, and driving the cleaning member 300 to move.

[0080] The control method of the electrostatic dust removal mechanism described above, the controller can drive the dust collection electrode 200 to rotate in the first cleaning mode to remove floating dust on the surface of the dust collection electrode 200, and the controller can drive the cleaning member 300 to move along the dust collection electrode 200 in the second cleaning mode to remove floating dust and pollutants on the surface of the dust collection electrode 200 by strong friction. The user can select different cleaning modes to clean the dust collection electrode 200 according to actual needs, so as to achieve better cleaning effect and meet the diversified cleaning needs of the user.

[0081] Preferably, the first threshold value is 20g, and the second threshold value is 30g.

[0082] In an embodiment, the step of detecting the dust collection quality of the dust collection electrode 200 includes: detecting the mass A1 of the dust collection electrode 200 before dust collection, detecting the mass A2 of the dust collection electrode 200 after dust collection, and calculating the difference between the mass A2 and the mass A1 to obtain the dust collection quality of the dust collection electrode 200.

[0083] Please refer to Figure 1 An air purifier in an embodiment includes the electrostatic dust removal mechanism described above.

[0084] It should be noted that the air purifier described above comprises a shell, a filtering mechanism and other components in addition to the electrostatic dust removal mechanism, and the electrostatic dust removal mechanism is arranged in the shell.
