Description

Technical Field

[0001] This utility model relates to the technical field of multi-electrode corona discharge devices, specifically a multi-electrode corona discharge device. Background Technology

[0002] A multi-electrode corona discharge device is a device that uses high-voltage current to generate a non-uniform electric field between electrodes, thereby causing ionization and discharge of a gaseous medium. During the discharge process, a corona layer forms around the electrodes, altering the surface properties of the contacting object. With the continuous development of corona technology, its applications have been widely extended to many fields. For example, in chemical production, corona treatment can effectively improve the adhesion of various substrates, thereby improving the quality of coating, printing, or laminating processes. Furthermore, stun guns used in public safety equipment are also based on the principle of corona discharge, achieving a non-lethal subjugation function through the instantaneous release of high-voltage pulses. In agriculture, forestry, and everyday environments, some rodent traps also employ corona technology, using high-voltage electric shocks to achieve efficient rodent control. Therefore, corona devices, due to their high efficiency and controllability, play an important role in various scenarios such as industrial processing, public safety, and pest control.

[0003] Although multi-electrode corona discharge devices are widely used in many fields, they still have certain structural defects in practical use, especially in terms of electrode protection. Currently, the electrode heads of most devices are usually directly exposed at the outermost end of the device, lacking necessary protective structures. If the device is accidentally dropped during operation, the exposed electrode heads are very likely to collide with the ground or other hard objects, resulting in electrode deformation, damage, or even malfunction. Such damage not only affects the uniformity and stability of corona discharge but also increases the frequency of equipment maintenance and operating costs. In addition, since the electrode heads are usually critical discharge components, their damage may also cause safety hazards, such as leakage or abnormal discharge. The shortcomings of existing designs in terms of drop and impact protection significantly reduce the durability and operational safety of the device and limit its applicability in mobile or complex environments.

[0004] Based on this, a multi-electrode corona discharge device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] In one embodiment, such as Figures 1-4As shown, a multi-electrode corona discharge device includes a multi-electrode corona discharge component 11. The multi-electrode corona discharge component 11 has a lighting lamp 12 and an electric shock head 13 at its end. The multi-electrode corona discharge component 11 has a first control switch 14 and a second control switch 15, which are electrically connected to the lighting lamp 12 and the electric shock head 13, respectively. A sliding tube 17 is slidably provided at the end of the multi-electrode corona discharge component 11. A protective cover 16 is fixedly provided at the end of the sliding tube 17. A connecting tube 22 is fixedly provided at the end of the multi-electrode corona discharge component 11. A limiting mechanism is provided inside the connecting tube 22 to fix the working position of the protective cover 16. The limiting mechanism facilitates fixing the working position of the protective cover 16, allowing the protective cover 16 to protect the electric shock head 13.

[0024] A protective baffle 18 and a connecting rod 19 are fixedly provided at one end of the sliding tube 17. The protective baffle 18 and the connecting rod 19 are symmetrically arranged. The upper end of the protective baffle 18 is provided with a first slot and a second slot respectively corresponding to the positions of the first control switch 14 and the second control switch 15. A connecting plate 21 is fixedly provided between the ends of the sliding tube 17 and the protective baffle 18. A protective outer plate 20 is fixedly provided on the outside of the multi-electrode corona component 11. The protective outer plate 20 is aligned with the positions of the protective baffle 18 and the connecting rod 19. A limiting groove is provided at the connection point. The connecting plate 21 is set inside the connecting pipe 22. A positioning groove is provided on the connecting pipe 22 at the position corresponding to the connecting plate 21. In use, when it is necessary to protect the electric shock head 13, the end of the protective cover 16 is positioned beyond the end of the electric shock head 13. At this time, the first slot is aligned with the first control switch 14, and the second slot is offset from the second control switch 15. This allows the protective cover 16 to protect the electric shock head 13 while the protective baffle 18 can prevent the second control switch 15 from being accidentally touched.

[0025] The limiting mechanism includes a fixing frame 24 symmetrically arranged on one side of the connecting plate 21. The connecting pipe 22 has mounting grooves corresponding to the positions on both sides of the connecting plate 21. A fixing box 27 is fixedly installed in each mounting groove. A sliding plate 26 is slidably installed inside each fixing box 27. A limiting frame 25 is symmetrically arranged on one side of each sliding plate 26. The limiting frame 25 is T-shaped. A through groove is provided in the middle of the fixing frame 24. Two second return springs 28 are symmetrically arranged between one side of the sliding plate 26 and one side of the interior of the fixing box 27. The two second return springs 28 are coaxially arranged with the two limiting frames 25. The connecting plate 21 has symmetrically arranged sliding holes. Guide rods are slidably installed in each sliding hole. The guide rods are fixed inside the connecting pipe 22. First return springs 23 are symmetrically arranged between one side of the connecting plate 21 and one end of the interior of the connecting pipe 22. The first return spring 23 is coaxially arranged with the two guide slide rods. In use, when the protective cover 16 needs to protect the electric shock head 13, the user presses the two sliding plates 26, causing the end of the limiting frame 25 to disengage from the end of the fixed frame 24. Under the action of the first return spring 23, the connecting plate 21 is pressed tightly against the end of the multi-electrode corona component 11. At the same time, the connecting plate 21 pushes the protective cover 16 to slide through the protective baffle 18 and the connecting rod 19. Then, the sliding plate 26 is released, so that the end of one limiting frame 25 is pressed tightly against the end of the fixed frame 24, thereby limiting the connecting plate 21. Similarly, when the electric shock head 13 needs to be used, the sliding plate 26 is pressed, and then the protective cover 16 is pushed to slide. The connecting plate 21 slides inside the connecting tube 22. Then, the sliding plate 26 is released, so that the other limiting frame 25 is pressed tightly against the fixed frame 24, thereby fixing the protective cover 16.

[0026] Both ends of the connecting plate 21 are fixedly provided with partitions, which are set at the positioning grooves to facilitate the sealing of the inside of the connecting pipe 22 during use.

[0027] One end of the connecting pipe 22 is fixedly provided with a fixed hinge seat 29, and a rotating hinge seat 30 is hinged on the fixed hinge seat 29. A hanging rope 31 is fixedly provided at the end of the rotating hinge seat 30, which facilitates the suspension and placement of the multi-electrode corona component 11 during use.

[0028] The protective cover 16 is cone-shaped. When in use, the protective cover 16 protects the electric shock head 13 and can concentrate the light emitted by the lighting lamp 12.

[0029] The outer side of the protective outer plate 20 is provided with anti-slip knurling, which facilitates the use of the multi-electrode corona component 11.

[0030] The above embodiment discloses a multi-electrode corona discharge device. When the protective cover 16 needs to protect the electric shock head 13, the user presses two sliding plates 26, causing the end of the limiting frame 25 to disengage from the end of the fixed frame 24. Under the action of the first return spring 23, the connecting plate 21 is pressed tightly against the end of the multi-electrode corona discharge component 11. At the same time, the connecting plate 21 pushes the protective cover 16 to slide through the protective baffle 18 and the connecting rod 19. Then, the sliding plates 26 are released, causing the end of one limiting frame 25 to press tightly against the end of the fixed frame 24, thereby enabling the protection of the electric shock head 13. When the connecting plate 21 is in a limiting position, the first slot is aligned with the first control switch 14, and the second slot is offset from the second control switch 15. This allows the protective cover 16 to protect the electric shock head 13 while the protective baffle 18 prevents the second control switch 15 from being accidentally touched. When the electric shock head 13 needs to be used, press the sliding plate 26 and then push the protective cover 16 to slide. The connecting plate 21 slides inside the connecting tube 22. Then release the sliding plate 26 so that the other limiting bracket 25 is in close contact with the fixing bracket 24, thereby fixing the protective cover 16.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
