Description

Technical Field

[0001] This utility model relates to the technical field of discharge plasma generators, and in particular to an enhanced discharge plasma generator with an adjustable electrode spacing structure. Background Technology

[0002] A discharge plasma generator is a device used to generate plasma, which is the fourth state of matter. It is generally considered to be a gas composed of a large number of free electrons and charged ions. Discharge plasma generators use electric fields or currents to ionize the gas, thereby forming plasma. However, most discharge plasma generators in the present technology still have problems that need to be solved.

[0003] Most existing discharge plasma generators cannot adjust the spacing between their two electrode plates. A fixed spacing limits the adjustment of the generated plasma's characteristics (such as density, temperature, and electron energy distribution). This affects the plasma's application performance, such as the efficiency and quality of material processing. Furthermore, most existing discharge plasma generators are difficult to disassemble and assemble, allowing impurities, oxides, or other deposits to accumulate during operation, which can impact performance. The difficult-to-disassemble design makes routine maintenance, cleaning, and electrode replacement challenging, thus affecting the long-term performance of the equipment. Therefore, there is a need to design an enhanced discharge plasma generator with an adjustable electrode spacing structure to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an enhanced discharge plasma generator with an adjustable electrode spacing structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An enhanced discharge plasma generator with an adjustable electrode spacing structure includes a base. Two movable stages are mounted on the top of the base. Two positioning rods are fixedly connected to the top of each end of the two movable stages. An electrode plate is mounted on the top of each movable stage, and an electrical wire is connected to the output end of each electrode plate. Two positioning grooves adapted to the positioning rods are formed at both ends of each electrode plate. A first mounting groove and two guide grooves are formed at both ends of the base. Rollers are mounted in the guide grooves, and fixed shafts pass through the rollers. The rollers are rotatably connected to the fixed shafts. Two fixed shafts at the same end are fixedly connected to the same L-shaped plate on their closest sides. The L-shaped plate passes through the movable stages and is slidably connected to them. A lifting plate is fixedly connected to one top of the L-shaped plate, and pins are fixedly connected to the bottom of both ends of the lifting plate. A connecting plate is fixedly connected to the electrode plate, and slots adapted to the pins are formed at both ends of the connecting plate. Each of the two first mounting grooves is provided with a drive mechanism for the movable stage. The adjustment mechanism for moving the stage employs a technique that adjusts the position of the electrode plates and fixes them as they move closer together. When the two electrode plates approach each other, a pin can be inserted into a slot to fix the slot, thus securing the electrode plate. Once fixed, the distance between the two electrode plates can be adjusted to regulate plasma characteristics such as density, temperature, and electron energy distribution according to specific application requirements, thereby optimizing plasma generation and application effects. Moving the two electrode plates away allows the pin to be removed from the slot, releasing the electrode plates from fixation. This effectively solves the problems mentioned in the background art where most existing discharge plasma generators cannot adjust the distance between the two electrode plates and are difficult to disassemble and assemble. It achieves the technical effect of easy adjustment of the distance between the electrode plates, simple operation, easy disassembly and assembly of the electrode plates, reduced difficulty in equipment maintenance and cleaning, and improved user convenience.

[0006] As a further embodiment of this utility model, the adjustment mechanism includes two first bearing seats, the first bearing seats are fixedly connected to the base, the inner walls of the inner rings of the bearings on the two first bearing seats are fixedly connected to the same adjusting screw, the adjusting screw is fitted with a screw nut, the outer wall of the screw nut is fixedly connected to a fixing block, and the top of the fixing block is fixedly connected to the bottom of the moving platform.

[0007] As a further embodiment of this utility model, a second mounting groove is provided at the top of both ends of the mobile platform, and the adjustment mechanism is disposed in the second mounting groove.

[0008] As a further embodiment of this utility model, the L-shaped plate is fixedly connected to a limiting plate on the side away from the lifting plate, and two limiting rods are provided through the limiting plate. The limiting plate is slidably connected to the limiting rods, and the bottom of the limiting rods is fixedly connected to the top of the moving platform.

[0009] As a further embodiment of this utility model, two sliding grooves are provided at the top of each end of the base, and a slider is provided in the sliding groove. The slider is slidably connected to the base, and the top of the two sliders at the same end is fixedly connected to the bottom of the moving platform.

[0010] As a further embodiment of this utility model, a worm gear is provided on one side of the base, and a worm is provided at the bottom of the worm gear for cooperation with it. A second bearing seat is sleeved on both ends of the worm, and the worm is rotatably connected to the second bearing seat. A knob is fixedly connected to one side of the worm, and an adjusting screw is fixedly connected to the worm gear. One end of the adjusting screw passes through the base, and the adjusting screw is rotatably connected to the base.

[0011] As a further embodiment of this utility model, two scale lines are provided on the top of one end of the base.

[0012] The beneficial effects of this utility model are as follows: Because of the use of an adjustment mechanism to adjust the position of the electrode plates and the technical means of fixing the electrode plates while bringing them closer together, the pin can be inserted into the slot to fix the slot, thus fixing the electrode plates. After fixing, the distance between the two electrode plates can be adjusted to adjust the plasma characteristics, such as density, temperature, and electron energy distribution, according to specific application requirements, thereby optimizing the plasma generation and application effect. Moving the two electrode plates away from each other allows the pin to be removed from the slot, thus releasing the electrode plates from fixation. This effectively solves the problems mentioned in the background art of most existing discharge plasma generators, such as the inability to adjust the distance between the two electrode plates and the difficulty in disassembling and assembling the electrode plates. Thus, it achieves the technical effect of easy adjustment of the distance between the electrode plates, simple operation, easy disassembly and assembly of the electrode plates, reduced difficulty in equipment maintenance and cleaning, and improved user convenience.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

A first mounting groove 3 and two guide grooves 4 are formed at both ends of the base 1. Rollers 5 are installed within the guide grooves 4. A fixed shaft 6 passes through the roller 5, and the roller 5 is rotatably connected to the fixed shaft 6. Two fixed shafts 6 at the same end are fixedly connected to the same L-shaped plate 7 on their close sides. The L-shaped plate 7 passes through the moving platform 2 and is slidably connected to the moving platform 2. A lifting plate 8 is fixedly connected to one of the top ends of the L-shaped plate 7. Pins 9 are fixedly connected to the bottom of both ends of the lifting plate 8. A connecting plate 10 is fixedly connected to the electrode plate 27. Slots 11 that are compatible with the pins 9 are opened at both ends of the connecting plate 10. Both first mounting slots 3 are provided with An adjustment mechanism is provided for driving the moving stage 2. This mechanism adjusts the position of the electrode plates and secures them as they move closer together. When the two electrode plates approach each other, a pin can be inserted into a slot to secure the slot, thus fixing the electrode plates. Once secured, the distance between the two electrode plates can be adjusted to regulate plasma characteristics such as density, temperature, and electron energy distribution, optimizing plasma generation and application effects. Moving the two electrode plates away from each other releases the pin from the slot, thus releasing the electrode plates. This effectively solves the problems mentioned in the background art where most existing discharge plasma generators cannot adjust the distance between the two electrode plates and are difficult to disassemble and assemble. This achieves the technical effect of easy adjustment of the distance between the electrode plates, simple operation, easy disassembly and assembly of the electrode plates, reduced difficulty in equipment maintenance and cleaning, and improved user convenience.

[0017] In this embodiment, the adjustment mechanism includes two first bearing seats 15, which are fixedly connected to the base 1. The inner walls of the inner rings of the bearings on the two first bearing seats 15 are fixedly connected to the same adjusting screw 16. A screw nut 17 is sleeved on the adjusting screw 16, and a fixing block 18 is fixedly connected to the outer wall of the screw nut 17. The top of the fixing block 18 is fixedly connected to the bottom of the moving platform 2.

[0018] In this embodiment, the top of both ends of the mobile platform 2 is provided with a second mounting groove 14, and the adjustment mechanism is disposed in the second mounting groove 14.

[0019] In this embodiment, the L-shaped plate 7 is fixedly connected to the limiting plate 13 on the side away from the lifting plate 8. Two limiting rods 12 are provided on the limiting plate 13. The limiting plate 13 is slidably connected to the limiting rods 12. The bottom of the limiting rods 12 is fixedly connected to the top of the moving platform 2. When the L-shaped plate 7 moves up and down, it will drive the limiting plate 13 to move along the limiting rods 12, ensuring the stability of the L-shaped plate 7 when it moves.

[0020] In this embodiment, two sliding grooves 19 are provided at the top of both ends of the base 1. A slider 20 is provided in the sliding groove 19. The slider 20 is slidably connected to the base 1. The top of the two sliders 20 at the same end is fixedly connected to the bottom of the moving platform 2. When the moving platform 2 moves, it will drive the slider 20 to move along the sliding groove 19, ensuring the stability of the moving platform 2 when it moves.

[0021] In this embodiment, a worm gear 21 is provided on one side of the base 1, and a worm 22 is provided at the bottom of the worm gear 21 for use with it. Both ends of the worm 22 are fitted with second bearing seats 23, and the worm 22 is rotatably connected to the second bearing seats 23. A knob 24 is fixedly connected to one side of the worm 22, and an adjusting screw 16 is fixedly connected to the worm gear 21. One end of the adjusting screw 16 passes through the base 1, and the adjusting screw 16 is rotatably connected to the base 1. Through the cooperation of the worm 22 and the second bearing seat 23, the position between the two electrode plates 27 can be kept stable without applying driving force to the knob 24. A protective box is provided on the worm gear 21 and the worm 22.

[0022] In this embodiment, two scale lines 26 are provided at the top of one end of the base 1. The distance between the two moving platforms 2 is determined by the scale lines 26, thereby adjusting the spacing between the two electrode plates 27.

[0023] Working principle: In use, connect wire 25 to the power supply equipment of the external device to supply power to the electrode plates 27. When it is necessary to adjust the distance between the two electrode plates 27, the operator can turn knob 24. Knob 24 will drive worm gear 22 to rotate, worm gear 22 will drive worm wheel 21 to rotate, worm wheel 21 will drive adjusting screw 16 to rotate, adjusting screw 16 will drive screw nut 17 to move, screw nut 17 will drive fixing block 18 to move, fixing block 18 will drive moving stage 2 to move, thereby adjusting the position of moving stage 2. Moving stage 2 will drive positioning rod 201 to move, positioning rod 201 will drive electrode plates 27 to move, thereby adjusting the distance between the two electrode plates 27. The distance between the two electrode plates 27 can be determined by the distance moved by moving stage 2 using scale line 26. When installing the two electrode plates 27, move the two moving stages 2 to their farthest points, then place the moving stages 2 on the positioning rod 201 for positioning. Turn knob 24 to move moving stage 2, so that the two electrode plates 2 are aligned. When the two moving platforms 2 move closer to each other, they will move the L-shaped plate 7, which in turn will move the fixed shaft 6. The fixed shaft 6 will then move the roller 5 along the inclined groove of the guide groove 4, allowing the roller 5 to descend during the lateral movement. This, in turn, will cause the L-shaped plate 7 to descend, which in turn will cause the lifting plate 8 to descend. The lifting plate 8 will then cause the pin 9 to descend. When the fixed shaft 6 moves into the transverse groove of the guide groove 4, the pin 9 will insert into the slot 11, thus restricting the position of the connecting plate 10 and fixing the electrode plate 27. This prevents the electrode plate 27 from detaching from the positioning rod 201, ensuring the stability of the electrode plate 27 and completing the assembly of the electrode plate 27. To remove the electrode plate 27, the two moving platforms 2 are moved further apart to their farthest points, causing the pin 9 to rise and move out of the slot 11. This releases the restriction on the connecting plate 10 and the electrode plate 27, allowing the electrode plate 27 to be removed from the positioning rod 201, completing the disassembly.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
