[0048] The advantages and features of the present invention and methods for achieving them will become apparent with reference to the embodiments described in detail below in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. This embodiment is provided only to complete the disclosure of the present invention and to enable those skilled in the art to fully understand the scope of the present invention, and the present invention is limited only by the scope of the claims. The same reference numerals represent the same constituent elements throughout the specification.

[0049] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0050] like Figure 2 and Figure 3 As shown, a dust removal device 100 is provided, including a power supply circuit 1, a first annular guide rail 2, a second annular guide rail 3, a conductive driving member 4, a dust removal assembly 5, an exhaust member 6 and a magnetic ring 7. The first annular guide rail 2 is arranged on the annular surface 2001 along the inner ring edge of the annular surface 2001, the second annular guide rail 3 is spaced from the first annular guide rail 2, and is arranged on the annular surface 2001 along the outer ring edge of the annular surface 2001, the conductive driving member 4 can be slidably connected to and electrically connected to the first annular guide rail 2 and the second annular guide rail 3, the conductive driving member 4 at least includes a first sub-segment 411 and a second sub-segment 412 located on the side of the first sub-segment 411 close to the second annular guide rail 3, the dust removal component 5 is arranged on the conductive driving member 4, the dust removal component 5 can move with the conductive driving member 4 and clean the annular surface 2001, the exhaust member 6 is used to exhaust the local area near the annular surface 2001, the magnetic ring 7 is concentrically arranged with the first annular guide rail 2, and the magnetic ring 7 is located on the side of the annular surface 2001 away from the first annular guide rail 2, the magnetic ring 7 can form a driving magnetic field on the side of the annular surface 2001 facing the first annular guide rail 2, wherein, due to Figure 2 The power circuit 1 and the magnetic ring 7 shown in the figure are both located on the side of the annular surface 2001 away from the first annular guide rail 2 and the second annular guide rail 3, so the power circuit 1 and the magnetic ring 7 are shown using dotted lines.

[0051] Among them, it can be understood that since the first annular guide rail 2 and the second annular guide rail 3 are both located on the same side of the annular surface 2001, the side of the annular surface 2001 away from the first annular guide rail 2 is equivalent to the side of the annular surface 2001 away from the second annular guide rail 3, and is also equivalent to the side of the annular surface 2001 away from the first annular guide rail 2 and the second annular guide rail 3, and the side of the annular surface 2001 toward the first annular guide rail 2 is equivalent to the side of the annular surface 2001 toward the second annular guide rail 3, and is also equivalent to the side of the annular surface 2001 toward the first annular guide rail 2 and.

[0052] The first annular guide rail 2 and the second annular guide rail 3 are electrically connected to the output end and the input end of the power supply circuit 1 respectively (that is, the first annular guide rail 2 can be electrically connected to the output end of the power supply circuit 1, and the second annular guide rail 3 can be electrically connected to the input end of the power supply circuit 1, or the first annular guide rail 2 can be electrically connected to the input end of the power supply circuit 1, and the second annular guide rail 3 can be electrically connected to the output end of the power supply circuit 1). When the power supply circuit 1 is operating, in the driving magnetic field, the Ampere force exerted on various parts of the conductive driving member 4 at least includes a component force parallel to the annular surface 2001 and pointing to the same side of the conductive driving member 4, and the Ampere force exerted on the first sub-segment 411 is smaller than the Ampere force exerted on the second sub-segment 412.

[0053] By setting the magnetic ring 7 to form a driving magnetic field on the side facing the annular surface 2001, and by setting the first annular guide rail 2, the second annular guide rail 3 and the conductive driving member 4, when the power supply circuit 1 is working, a current can be generated in the conductive driving member 4 from the connection at the first annular guide rail 2 to the connection at the second annular guide rail 3, or from the connection at the second annular guide rail 3 to the connection at the first annular guide rail 2, so that the conductive driving member 4 can be subjected to an Ampere force substantially perpendicular to the length direction of the conductive driving member 4, and the Ampere force at each location of the conductive driving member 4 includes at least a parallel The force is directed to the same side of the annular surface 2001 and toward the conductive driving member 4, so that the conductive driving member 4 can slide along the first annular guide rail 2 and the second annular guide rail 3 under the action of the Ampere force, and then can drive the dust removal component 5 to move, so as to realize the cleaning of the annular surface 2001 within a certain area by the dust removal component 5, so as to automatically clean and collect the impurity particles accumulated within the certain area into the suction action area of ​​the vacuum member 6, so that the vacuum member 6 can remove the impurity particles, thereby realizing the automatic cleaning of the impurity particles accumulated on the annular surface 2001 within a certain area.

[0054] Furthermore, when the conductive driving member 4 moves along the first annular guide rail 2 and the second annular guide rail 3 around the center of the annular surface 2001, the moving speed of the portion of the conductive driving member 4 close to the outer edge of the annular surface 2001 is greater than the moving speed of the portion of the conductive driving member 4 close to the inner edge of the annular surface 2001. Therefore, by making the conductive driving member 4 include at least a first sub-segment 411 and a second sub-segment 412 located on a side of the first sub-segment 411 close to the second annular guide rail 3, and making the Ampere force on the first sub-segment 411 smaller than that on the second sub-segment 412, the conductive driving member 4 can be easily moved. 2, the Ampere force exerted on the conductive driving member 4 can make the acceleration of the portion of the conductive driving member 4 close to the second annular guide rail 3 greater than the acceleration of the portion of the conductive driving member 4 close to the first annular guide rail 2, thereby making the movement speed of the portion of the conductive driving member 4 close to the outer edge of the annular surface 2001 greater than the movement speed of the portion of the conductive driving member 4 close to the inner edge of the annular surface 2001, thereby making the Ampere force exerted on the conductive driving member 4 more suitable for making the conductive driving member 4 move along the first annular guide rail 2 and the second annular guide rail 3 around the center of the annular surface 2001.

[0055] It can be understood that according to the left-hand rule, in order to make the Ampere force received at various locations of the conductive driving component 4 include at least a force component parallel to the annular surface 2001 and pointing to the same side of the conductive driving component 4, the magnetic flux lines of the driving magnetic field must not be parallel to the annular surface 2001, and must all point from the side facing the annular surface 2001 to the side facing away from the annular surface 2001, or from the side facing away from the annular surface 2001 to the side facing the annular surface 2001.

[0056] Preferably, the magnetic flux lines of the driving magnetic field can be made substantially perpendicular to the annular surface 2001, so that when the Ampere force on the conductive driving member 4 remains unchanged, the Ampere force included in the same side component parallel to the annular surface 2001 and directed to the conductive driving member 4 is larger. In other words, the utilization efficiency of the Ampere force is higher, and the conductive driving member 4 can be driven to move along the first annular guide rail 2 and the second annular guide rail 3 around the center of the annular surface 2001 with lower energy consumption. Figure 2 As shown, Figure 2 It is shown that the magnetic flux lines of the driving magnetic field are approximately perpendicular to the annular surface 2001 and point to Figure 2 within the paper.

[0057] Optionally, the magnetic ring 7 may be located on the side facing away from the annular surface 2001 to prevent the magnetic ring 7 from affecting the operation of other devices and equipment on the side facing the annular surface 2001 .

[0058] Since the Ampere force exerted on the conductive driving component 4 is proportional to the strength of the cut magnetic field and the magnitude of the current flowing in the conductive driving component 4, based on this, the Ampere force exerted on the first sub-segment 411 can be made smaller than the Ampere force exerted on the second sub-segment 412 by making the strength of the driving magnetic field cut by the first sub-segment 411 smaller than the strength of the driving magnetic field cut by the second sub-segment 412, and / or making the current flowing in the first sub-segment 411 smaller than the current flowing in the second sub-segment 412.

[0059] Specifically, when the intensity of the driving magnetic field cut by the first sub-segment 411 is smaller than the intensity of the driving magnetic field cut by the second sub-segment 412, as shown in FIG. Figure 3 As shown, in an optional embodiment, the magnetic ring 7 is located on the outer peripheral side of the second annular guide rail 3, so that the magnetic ring 7 can form a driving magnetic field on the side facing the annular surface 2001, and the magnetic field strength is stronger in the part closer to the second annular guide rail 3, and weaker in the part closer to the first annular guide rail 2, so that the strength of the driving magnetic field cut by the first sub-segment 411 is smaller than the strength of the driving magnetic field cut by the second sub-segment 412.

[0060] like Figure 2 and Figure 4 As shown, in another optional embodiment, the dust removal device 100 includes two magnetic rings 7, one of the two magnetic rings 7 is located on the inner side of the first annular guide rail 2, and the other is located on the outer side of the second annular guide rail 3, and the directions of the magnetic fields formed by the two magnetic rings 7 on the annular surface 2001 facing the side of the first annular guide rail 2 are opposite, and the magnetism of the magnetic ring 7 located on the inner side of the first annular guide rail 2 is smaller than the magnetism of the magnetic ring 7 located on the outer side of the second annular guide rail 3, so that the magnetic field formed by the magnetic ring 7 located on the outer side of the second annular guide rail 3 can be weakened by the magnetic field formed by the magnetic ring 7 located on the inner side of the first annular guide rail 2, so that the strength of the driving magnetic field gradually increases from the first annular guide rail 2 to the second annular guide rail 3, so that the strength of the driving magnetic field cut by the first sub-segment 411 is smaller than the strength of the driving magnetic field cut by the second sub-segment 412. In addition, the magnetic field formed by the magnetic ring 7 located on the inner side of the first annular guide rail 2 can weaken the magnetic field formed by the magnetic ring 7 located on the outer peripheral side of the second annular guide rail 3. On the one hand, the difference in magnetic field strength between the portion of the driving magnetic field close to the first annular guide rail 2 and the portion close to the second annular guide rail 3 can be increased, so that the difference between the Ampere force exerted on the first sub-segment 411 and the Ampere force exerted on the second sub-segment 412 can be further increased, so as to further make the force exerted on the conductive driving component 4 more reasonable. On the other hand, the magnetic field strength of each position of the formed driving magnetic field can be more flexibly adjusted by selecting magnetic rings 7 with different magnetic properties.

[0061] When the power supply circuit 1 is operated, the current flowing in the first sub-segment 411 is smaller than the current flowing in the second sub-segment 412. Figures 4 to 6 As shown, optionally, the dust removal device 100 may also include at least one third annular guide rail 8, the third annular guide rail 8 is concentrically arranged on the annular surface 2001 with the first annular guide rail 2, and the third annular guide rail 8 is located between the first annular guide rail 2 and the second annular guide rail 3, the conductive driving member 4 includes a plurality of sub-segments 41 connected in sequence, the plurality of sub-segments 41 include the aforementioned first sub-segment 411 and the second sub-segment 412, the sub-segments 41 are arranged in sequence along the direction from the first annular guide rail 2 to the second annular guide rail 3, and the two opposite ends of each sub-segment 41 are respectively electrically connected to two adjacent annular guide rails, the dust removal device 100 also includes a current regulating mechanism (not numbered in the figure), the current regulating mechanism is at least electrically connected to the two annular guide rails to be connected in parallel with the sub-segment 41 between the two annular guide rails, and the current regulating mechanism can at least regulate the current flowing in the sub-segment 41 between the two annular guide rails so that the current flowing in the first sub-segment 411 is less than the current flowing in the second sub-segment 412.

[0062] When the dust removal device 100 further includes a plurality of third annular guide rails 8, the radii of the plurality of third annular guide rails 8 may be increased sequentially so as to be arranged concentrically and sequentially spaced.

[0063] Optionally, the current regulating mechanism may be located on the side facing away from the annular surface 2001 to prevent the current regulating mechanism from affecting the operation of other devices and equipment on the side facing the annular surface 2001 .

[0064] like Figure 4 As shown, in an optional embodiment, the current regulating mechanism includes a resistor 91, so that the resistor 91 can be connected in parallel to the sub-segment 41 between the two annular guides through the two annular guides, so that the current can be partially diverted to the place where it flows through the resistor 91, so as to reduce the current flowing through the sub-segment 41 between the two annular guides. Specifically, at least the first sub-segment 411 is connected in parallel to the resistor 91, so that the current flowing in the first sub-segment 411 can be reduced through the resistor 91.

[0065] Optionally, the current regulating mechanism includes multiple resistors 91, which are electrically connected between two annular guide rails, and at least one of the two annular guide rails electrically connected to different resistors 91 is different. In other words, for any two resistors 91, both ends of the two resistors 91 are electrically connected to different annular guide rails, or one end of the two resistors 91 may be connected to the same annular guide rail, and the other ends of the two resistors 91 are connected to different annular guide rails, so that the current flowing in more sub-segments 41 can be adjusted through the resistors 91, so as to more flexibly adjust the Ampere force exerted on more sub-segments 41 in the driving magnetic field.

[0066] Exemplarily, a resistor 91 may be connected between any two adjacent annular guide rails, so that each sub-segment 41 is respectively connected in parallel with a resistor 91, so that the current flowing in each sub-segment 41 can be flexibly adjusted by adjusting the resistance of the resistor 91 connected in parallel to each sub-segment 41, thereby flexibly adjusting the Ampere force exerted on more sub-segments 41 in the driving magnetic field.

[0067] Optionally, the current shunting capability of the resistor 91 can be changed by replacing the resistor 91 with a different resistance value, or at least part of the resistor 91 can be a variable resistor, so that the resistance value of the resistor 91 can be adjusted without replacing the resistor 91.

The current regulating mechanism includes two sub-power sources 11 and a resistor 91. The two sub-power sources 11 are respectively connected in parallel to the two sub-segments 41 through the annular guide rails, and the resistor 91 is connected between the first annular guide rail 2 and the second annular guide rail 3. In other words, the resistor 91 is connected in parallel to the conductive driving member 4 as a whole, so that the current flowing in the first sub-segment 411 and the second sub-segment 412 can be flexibly adjusted by controlling the conductive connector 43 to disconnect or connect or adjust the specific resistance value of the conductive connector 43, and cooperating with the sub-power source 11 to control the two sub-segments 41 respectively.

The two insulating connectors 42 and the two conductive connectors 43 are respectively located between one end of a sub-segment 41 and the third annular guide rail 8 close to the first annular guide rail 2 and close to the second annular guide rail 3. The remaining one insulating connector 42 and one conductive connector 43 current regulating mechanism include four sub-power supplies 11 and two resistors 91. The two sub-power supplies 11 are respectively connected in parallel to the two sub-segments 41 through the annular guide rails. Among the two resistors 91, one is connected in parallel to the two sub-segments 41 closest to the first annular guide rail 2, and the other is connected in parallel to the two sub-segments 41 closest to the second annular guide rail 3.

Figure 4 As shown), the adsorbable surface area of ​​the dust removal component 5 for charged foreign particles can be increased by increasing the number of anode adsorbents 52, thereby improving the collection capacity of the dust removal component 5 for charged foreign particles.

[0093] Optionally, the anode adsorbent 52 is a porous structure. For example, the anode adsorbent 52 may be a sheet structure including but not limited to a mesh structure with multiple holes, thereby increasing the surface area of ​​the anode adsorbent 52 and further improving the dust removal component 5's ability to collect charged impurity particles.

[0094] Optionally, the component seat 50 is a cover-shaped structure with an inner cavity 501. The component seat 50 has an opening 502 connected to the inner cavity 501 on the side facing the annular surface 2001. The discharge member 51 and the anode adsorption member 52 are both located inside the inner cavity 501, so that the component seat 50 can prevent the charged impurity particles entering the inner cavity 501 from scattering, so as to improve the dust removal effect of the dust removal component 5. In addition, such a setting can also make it possible for the conductive driving member 4 to drive the dust removal component 5 to move to the vicinity of the suction action area of ​​the suction member 6, and the opening 502 is roughly aligned with the through hole 2001a, so that the suction member 6 can extract the impurity particles collected in the inner cavity 501 through the through hole 2001a.
