[0002] In medical consultation settings, excimer light sources are used to quickly sterilize the air, reducing cross-infection between doctors and patients, especially the impact of patients on doctors, which is of great significance in protecting doctors' health.
[0003] Currently, excimer light sources are usually placed on the ceiling of the clinic. Existing 254nm ultraviolet disinfection products cannot directly irradiate the human body, especially causing damage to the eyes. 222nm (KrCl) excimer ultraviolet disinfection products have a power of less than 200W and require long-term irradiation, resulting in a longer disinfection time. At the same time, the excimer light source generates high internal temperatures during operation, and the excimer light source cannot cool itself, which affects the lifespan of the excimer light source. Utility Model Content

[0022] 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.
[0023] Reference Figures 1-6 An excimer light source with a self-cooling system and a wound electrode includes a mounting base and a sterilizing discharge tube 3. The mounting base consists of a housing 1 and a back cover 2. The discharge tube 3 consists of a quartz tube, a ground electrode, a high voltage electrode, and a light source tube. A positioning seat 4 extending into the housing 1 is fixedly installed on the discharge tube 3.
[0024] The outer casing 1 has a U-shaped structure. The rear cover 2 is threaded with bolts connecting to the outer casing 1. The positioning seat 4 is threaded with bolts connecting to the outer casing 1. (See the attached instruction manual.) Figure 2 As shown, the grounding electrode and the high-voltage electrode have a spiral structure. The spiral structure of the grounding electrode and the high-voltage electrode effectively improves the power density of the light source, so that the maximum power of the light source can reach 2000W. The quartz tube consists of an inner tube and an outer tube. The water inlet 8 is connected to the inner tube of the quartz tube, and the water outlet 9 is connected to the outer tube of the quartz tube.
[0025] The rear cover 2 is provided with a buffer pad 5 that moves against the positioning seat 4. The discharge tube 3 is provided with a terminal 7 extending into the outer shell 1. The outer shell 1 is connected to a junction plate 6 by screws. The positioning seat 4 is provided with an inlet 8 and an outlet 9 that are connected to the discharge tube 3. The outer shell 1 is connected with an inlet pipe 10 and an outlet pipe 11 that extend into the inlet 8 and outlet 9 respectively. The water source extends into the inlet 8 through the inlet pipe 10 and then flows into the inner and outer tubes through the inner tube of the quartz tube, which can dissipate heat from the discharge tube 3 as a whole, thereby improving the service life of the discharge tube 3. It can be started and stopped quickly at any time, avoiding the disadvantage of the hot cathode mercury vapor ultraviolet lamp (center wavelength 254nm) light source requiring preheating. The outer shell 1 is provided with a clamping structure to clamp the inlet pipe 10.
[0026] The clamp structure includes an installation plate 12 integrally connected to the water inlet pipe 10, a limiting post 13 extending into the installation plate 12 is slidably sleeved on the positioning seat 4, a support plate 15 and a movable seat 17 are integrally connected to the limiting post 13, and a spring 16 is welded between the support plate 15 and the outer shell 1.
[0027] The positioning seat 4 has a limiting groove 14 that guides the limiting post 13. The limiting groove 14 guides the limiting post 13, allowing the limiting post 13 to extend smoothly into the mounting plate 12. The limiting post 13 is horizontally positioned on both sides of the mounting plate 12. The moving seat 17 extends into the limiting groove 14 on one side. The spring 16 is horizontally welded and resets the support plate 15 and the limiting post 13. When the moving seat 17 is unloaded, the spring 16 can drive the limiting post 13 and the support plate 15 back to their initial positions.
[0028] A retaining plate 19 is placed on the outer casing 1, and an abutment block 20 that moves against the movable seat 17 is fixedly installed on the retaining plate 19. A fixing bolt connected to the outer casing 1 is threaded on the retaining plate 19. A clamping groove 18 is provided on the movable seat 17 to clamp the abutment block 20. After the water inlet pipe 10 is installed into the water inlet 8, the two limiting posts 13 can extend into the limiting groove 14 in the mounting plate 12. By installing the retaining plate 19, the retaining plate 19 can drive the abutment block 20 to extend into the clamping groove 18, thereby locking the position of the limiting posts 13, making the installation of the water inlet pipe 10 more convenient.
[0029] The functional principle of this utility model can be explained through the following operation methods:
[0030] Insert the water outlet pipe 11 into the water outlet 9 and the water inlet pipe 10 into the water inlet 8. The water inlet pipe 10 drives the mounting plate 12 to extend into the outer shell 1. When the mounting plate 12 moves down, it moves against the limiting post 13, so that the lower end of the water inlet pipe 10 extends to the water inlet 8. When the limiting post 13 and the limiting groove 14 correspond to each other, the limiting post 13 extends into the limiting groove 14 in the mounting plate 12 under the action of the spring 16. Place the clamping plate 19 on the outer shell 1, so that the clamping plate 19 drives the contact block 20 to extend into the clamping groove 18 in the moving seat 17. Use the fixing bolt to connect the clamping plate 19 and the outer shell 1.
[0031] The light emitted by the discharge tube 3 after it is powered on can disinfect and sterilize.
[0032] 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.
