When the fan is running, the airflow flows into the air inlet of the electrostatic adsorption device 1, flows through the electrostatic adsorption device 1, flows out of the air outlet of the electrostatic adsorption device 1, and flows into the fan, and the flow direction of the airflow is shown by an arrow in fig. 2.
Each insulating connector comprises an inner side piece 3 and an outer side piece 4. The ends of the fixing rods are fixed to the inner side member 3, specifically, the ends of the fixing rods are fixed at the center of the inner side member 3, as shown in fig. 3. With the present embodiment, the outer member 4 also serves to fix the end of the fixing rod. The fixing bars are exposed only to the inner side of the outer ground plate, specifically, the fixing bars are exposed only to the inside of the electrostatic adsorption device 1, that is, the fixing bars are exposed only between the first outer ground plate 2 and the second outer ground plate.
The number of the fixed rods is multiple, and the fixed rods specifically comprise five grounding pole plate fixed rods, five adsorption pole plate fixed rods and two ionization wire fixed rods 7. Fig. 3 is a view of the internal structure of the electrostatic adsorption device 1 with the second outer ground plate removed, in which the adsorption plate, the internal ground plate, five ground plate fixing bars, four adsorption plate fixing bars, and other elements are not yet installed. The ionizing wire fixing lever 7 is provided to be adapted to fix the ionizing wire 8 of the electrostatic adsorption apparatus 1, as shown in fig. 3. The adsorption plate fixing lever is provided to be suitable for fixing the adsorption plate of the electrostatic adsorption device 1. The ground plate fixing lever is provided to be suitable for fixing the internal ground plate of the electrostatic adsorption device 1. In fig. 2, seven outer side members 4 are fixed on the first outer side ground plate 2, wherein the insulating connecting members to which the two outer side members 4 at the bottom belong are used for fixing the ionizing wire fixing rod 7; and the other five insulating connecting pieces to which the outer side pieces 4 belong are all used for fixing the adsorption polar plate fixing rod. As shown in fig. 2, five mounting holes 9 are formed in the first outer ground plate 2 for mounting the insulating connectors, and the insulating connectors mounted in these mounting holes 9 are used for fixing the ground plate fixing rod (not shown).
A plurality of insulating connectors are fixed to the first outer ground plate 2, and an end of an adsorption plate fixing rod (hereinafter, the adsorption plate fixing rod is referred to as a first adsorption plate fixing rod 6) is fixed to one of the insulating connectors (hereinafter, the insulating connector is referred to as a first insulating connector), and as shown in fig. 3, the first adsorption plate fixing rod 6 is spaced apart from an edge of the inner member 3 by a predetermined distance. The first adsorption plate fixing rod 6 is isolated from the first outer ground plate 2 (the first adsorption plate fixing rod 6 is isolated from the first outer ground plate 2 by providing a first insulating connector therebetween), and as shown in fig. 2 and 3, the first outer ground plate 2 is held between the inner member 3 of the first insulating connector and the outer member 4 of the first insulating connector. The inner part 3 of the first insulating connection is located inside the first outer ground plate 2 and the outer part 4 of the first insulating connection is located outside the first outer ground plate 2. First absorption polar plate dead lever 6 connects in advance and is fixed in inside piece 3, the tip of first absorption polar plate dead lever 6 is provided with the external screw thread, outside piece 4 is provided with the internal thread, when fixed, the tip of first absorption polar plate dead lever 6 passes the mounting hole that corresponds on first outside ground plate 2 from inside to outside (keep apart through insulating element between first absorption polar plate dead lever 6 and this mounting hole), the outer wall of inside piece 3 pastes and leans on the inner wall in first outside ground plate 2, then, be fixed in the tip of first absorption polar plate dead lever 6 with outside piece 4 through threaded connection's mode, outside piece 4 supports and leans on the outer wall in first outside ground plate 2.
First outside ground connection polar plate 2 is provided with fretwork portion, and fretwork portion encircles the setting of first insulation connecting piece, specifically, and fretwork portion is opening convex up, as shown in fig. 2 and 3. The term "the hollow portion is in the form of an arc with an opening facing upward" means that the hollow portion is in the form of an arc as a whole, and the opening of the arc faces upward. Actually, the circular arc-shaped opening is a plate body of the first outer side grounding polar plate 2, and is not in a hollow structure.
Part of the edge of the inner member 3 of the first insulating connecting member extends to the hollow area 5 of the hollow portion, as shown in fig. 2 and 3, that is, the bottom edge, the left edge and the right edge of the inner member 3 of the first insulating connecting member all extend to the hollow area 5 between the inner circular arc edge and the outer circular arc edge of the hollow portion, and the bottom edge, the left edge and the right edge of the inner member 3 of the first insulating connecting member all cross the inner circular arc edge of the hollow portion and do not reach the outer circular arc edge of the hollow portion. The inner side arc edge of the hollow part and the edge of the inner side part 3 are separated by a certain distance, and the outer side arc edge of the hollow part and the edge of the inner side part 3 are also separated by a certain distance. Therefore, inside the electrostatic adsorption device 1, when viewed in a horizontal direction perpendicular to the inner wall of the first outer ground electrode plate 2 toward the first insulating connector, the inner circular arc edge of the hollow portion is blocked by the inner member 3 of the first insulating connector (the outer circular arc edge of the hollow portion is not blocked by the inner member 3 of the first insulating connector). The inner side arc edge of the hollow part is attached to the outer wall of the inner part 3, as shown in fig. 2, the edge of the outer part 4 of the first insulating connecting part is surrounded by the inner side arc edge of the hollow part, and a certain distance is formed between the edge of the outer part 4 of the first insulating connecting part and the inner side arc edge of the hollow part.
The function of the second outer ground plate is the same as that of the first outer ground plate 2, and a plurality of insulating connectors are fixed to the second outer ground plate. One end of the same fixing rod is fixed to the insulating connector on the first outer grounding plate 2, and the other end is fixed to the insulating connector on the second outer grounding plate. The second outer ground plate may also have a hollow portion thereon to achieve the same function, and the specific structure is the same as that of the hollow portion of the first outer ground plate 2, please refer to the above, which is not repeated herein.
Further, outer casing members (not shown) are respectively covered on the outer sides of the first outer ground plate 2 and the second outer ground plate to respectively shield the outer casing member 4 on the first outer ground plate 2 and the outer casing member on the second outer ground plate.
The foregoing is merely one embodiment of the present application and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, in the above embodiment, only one hollow-out portion is exemplarily provided on the first outer ground plate, and actually, a plurality of hollow-out portions may also be provided, where each hollow-out portion corresponds to each insulating connecting piece on the first outer ground plate one to one. The specific number of the hollowed-out parts can be designed and determined according to specific anti-creeping requirements. For example, any grounding electrode plate fixing rod corresponds to a hollow-out portion on the first outer grounding electrode plate, any adsorption electrode plate fixing rod corresponds to a hollow-out portion on the first outer grounding electrode plate, and any ionization wire fixing rod corresponds to a hollow-out portion on the first outer grounding electrode plate. Similarly, the second outer-side grounding pole plate can also be provided with one or more hollow parts, and the specific number of the hollow parts is designed and determined according to specific anti-creeping requirements.
The foregoing is merely one embodiment of the present application and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the hollow portion may be located only below the insulating connecting member, and the specific shape of the hollow portion may be a circle, an ellipse, a rectangle, a square, an irregular shape, or the like. Preferably, the bottom edge of the inner side member of the insulating connecting member extends to the hollow area of the hollow part.
The foregoing is merely one embodiment of the present application and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the specific fixing method between the insulating connector and the outer ground plate and the specific fixing method between the end of the fixing rod and the insulating connector are not limited to those shown in the embodiment, and the related fixing method may be used.
The foregoing is merely one embodiment of the present application and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, when the electrostatic adsorption device is viewed from the first insulating connector along a horizontal direction perpendicular to the inner wall of the first outer ground electrode plate, the inner arc edge of the hollow portion may not be shielded by the inner member of the first insulating connector, as shown in fig. 4; in other words, the inner member of the first insulating connector is hidden from view by the first outer ground plate when viewed from the outside of the electrostatic adsorption device in a horizontal direction perpendicular to the outer wall of the first outer ground plate toward the first insulating connector. However, this does not increase the creepage distance; however, it is still helpful to reduce the accumulation of grease on the inner side of the insulated connector, thereby reducing the risk of creepage.
The foregoing is merely one embodiment of the present application and other embodiments may be devised by adding, deleting, modifying or replacing certain features. For example, the second outer ground plate may be provided with no hollow portion, and only the first outer ground plate may be provided with a hollow portion. Or, the first outer grounding polar plate is not provided with the hollow part, and only the second outer grounding polar plate is provided with the hollow part.
The elements of the different embodiments may be combined with each other in any feasible manner to achieve the object of the application.
It should be additionally noted that the present application should not be construed as limited to the above-described embodiments, but should be construed to cover all possible embodiments as determined by the claims that follow when taken in conjunction with the disclosure herein. Therefore, any simple modification, equivalent change and modification of the above embodiments according to the technical essence of the present application shall fall within the protection scope of the technical solution of the present application, unless the technical essence of the present application departs from the content of the technical solution of the present application.
