[0002] Excimer lamps use high-voltage, high-frequency radiation from outside the tube to bombard the rare gas inside, emitting ultraviolet light. Unlike low-pressure mercury lamps, excimer lamps do not contain mercury or other harmful substances in their discharge tubes, resulting in less negative environmental impact. They are widely used in industries such as medicine, water treatment, environmental protection, chemicals, and surface treatment. When used for water treatment, the water is typically contained within a light-transmitting container while the excimer lamp is outside. The light from the excimer lamp penetrates the container and irradiates the water, making excimer lamps less effective for water treatment.

[0018] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

In addition, the terms "first", "second" and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] As shown in Figures 1-3, a quasi-molecular lamp device according to a preferred embodiment of the present invention includes a lamp tube 1, an inner electrode 2 and an electrode tube 3. A sealed cavity 11 is provided in the lamp tube 1, and the cavity 11 is filled with discharge gas. The inner electrode 2 is provided in the cavity 11, and one end of the inner electrode 2 is connected to the conductive component 4. The conductive component 4 extends out of the cavity 11, which is convenient for the conductive component 4 to be connected to the power supply, so that the inner electrode 2 can be connected to the power supply through the conductive component 4. The lamp tube 1 is inserted into the electrode tube 3, and there is a gap between the outer side of the lamp tube 1 and the inner side of the electrode tube 3 to form a flow channel 5. One end of the electrode tube 3 is provided with an input port 31 connected to the flow channel 5, and the other end of the electrode tube 3 is provided with an output port 32 connected to the flow channel 5. Both ends of the electrode tube 3 are respectively connected with sealing fixings 6 for blocking the flow channel 5, and the sealing fixings 6 are fixedly connected to the lamp tube 1.

[0021] The working principle of this embodiment is as follows: during assembly, firstly, the lamp tube 1 (the cavity 11 is provided with an inner electrode 2 and filled with discharge gas) is inserted into the electrode tube 3, and then the sealing fixture 6 is provided at both ends of the electrode tube 3, and then the sealing fixture 6 is fixedly connected to the lamp tube 1 and the sealing fixture 6 is connected to the electrode tube 3 to fix the lamp tube 1, so that a flow channel 5 is formed between the outside of the lamp tube 1 and the inside of the electrode tube 3, and the sealing fixture 6 blocks the port of the flow channel 5; during use, the electrode tube 3 is connected to the power supply, and the inner electrode 2 is connected to the power supply through the conductive component 4. Since the electrode tube 3 is made of conductive material, for safety reasons, generally, the electrode tube 3 is connected to a low-voltage power supply, and the inner electrode 2 is connected to a high-voltage power supply. In addition, An insulating layer can be coated on the outer surface of the electrode tube 3 to prevent electric shock accidents; after power is turned on, an arc will be generated between the electrode tube 3 and the inner electrode 2 to bombard the discharge gas in the cavity 11, thereby emitting ultraviolet light. At this time, water enters the flow channel 5 from the input port 31. Since the sealing fixings 6 located at both ends of the electrode tube 3 respectively block the flow channel 5, the water will flow along the flow channel 5 and finally be discharged through the output port 32. During the flow of water, the water will be irradiated by ultraviolet light, thereby achieving sterilization of the water; a flow channel 5 is provided inside the excimer lamp device, and water can be supplied to the flow channel 5. When working, the lamp tube 1 can be regarded as immersed in water. The ultraviolet light emitted by the device can directly irradiate the water, and the treatment effect is good.

[0022] Exemplarily, the sealing fixing member 6 is provided with a fixing hole 61 that cooperates with the lamp tube 1 , and the lamp tube 1 is positioned and fixed by the cooperation between the fixing hole 61 and the lamp tube 1 .

[0023] Exemplarily, the sealing fixture 6 is detachably connected to the electrode tube 3, such as the sealing fixture 6 is threadedly connected to the end of the electrode tube 3, the two ends of the lamp tube 1 respectively extend out of the electrode tube 3, and the end of the lamp tube 1 is embedded in the sealing fixture 6, that is, the fixing hole 61 is provided at one end of the sealing fixture 6 close to the lamp tube 1, and the fixing hole 61 is a blind hole. The positioning and installation of the lamp tube 1 are achieved by the cooperation between the end of the lamp tube 1 and the fixing hole 61, and the sealing fixture 6 covers the part of the lamp tube 1 extending out of the electrode tube 3, thereby protecting the lamp tube 1, and the conductive component 4 extends to the outside through the sealing fixture 6, that is, the sealing fixture 6 is provided with a The conductive component 4 extends out of the wiring hole to the outside, and the conductive component 4 extends out of the cavity 11 and extends out of the wiring hole to the outside. Generally, the wiring hole matches the part of the conductive component 4 that passes through the sealing fixture 6. In this embodiment, the sealing fixture 6 is also connected to a sealing joint. The conductive component 4 passes through the sealing fixture 6 and then extends out of the outside through the sealing joint to ensure sealing. In addition, in other embodiments, the end of the lamp tube 1 can pass through the sealing fixture 6, as shown in Figure 1, that is, the fixing hole 61 is a through hole that matches the lamp tube 1. The end of the lamp tube 1 passes through the fixing hole 61, which can facilitate assembly and facilitate the connection of the conductive component 4 to the power supply.

[0024] Exemplarily, both ends of the lamp tube 1 are respectively provided with sealing rings 7 for sealing the flow channel 5, and the sealing fixing part 6 is provided with a mounting groove 62 that cooperates with the sealing ring 7. The setting of the sealing ring 7 can increase the sealing performance of the device and prevent water in the flow channel 5 from leaking out.

[0025] Exemplarily, the conductive component 4 includes a conductive sheet 41 and a conductive lead 42. A clamping portion 12 is provided at one end of the lamp tube 1, and the conductive sheet 41 is fixed in the clamping portion 12. The end of the inner electrode 2 close to the clamping portion 12 extends into the clamping portion 12 and is connected to the conductive sheet 41. The conductive sheet 41 is connected to one end of the conductive lead 42, and the other end of the conductive lead 42 extends out of the clamping portion 12. The setting of the clamping portion 12 plays a sealing role to ensure the sealing of the cavity 11. In addition, since the conductive sheet 41 is fixed in the clamping portion 12, and the inner electrode 2 is connected to the conductive sheet 41, that is, the end of the inner electrode 2 connected to the conductive sheet 41 is also clamped and fixed, thereby achieving the fixation of the inner electrode 2 and preventing the inner electrode 2 from displacement. The wire lead extends out of the clamping portion 12, which facilitates its connection to the power supply. The inner electrode 2 can be connected to the power supply through the conductive component 4.

[0026] Since the device mainly generates an arc between the inner side of the electrode tube 3 and the inner electrode 2 when working, the end of the inner electrode 2 generally does not need to extend out of the electrode tube 3. In order to facilitate the installation of the lamp tube 1, the end of the lamp tube 1 generally extends out of the electrode tube 3. At this time, in order to facilitate the positioning and installation of the inner electrode 2, for example, a positioning piece 13 is fixed in the cavity 11, and the positioning piece 13 is located in the electrode tube 3. The positioning piece 13 is provided with a positioning hole. One end of the inner electrode 2 extends into the positioning hole and is located in the electrode tube 3. The end of the inner electrode 2 cooperates with the positioning hole to facilitate the positioning of the inner electrode 2. The positioning piece 13 is located in the electrode tube 3, so that the end of the lamp tube 1 can extend out of the electrode tube 3, while the end of the inner electrode 2 does not extend out of the electrode tube 3. It can be understood that both ends of the inner electrode 2 can be positioned by the positioning piece 13.

[0027] Exemplarily, the lamp tube 1 and the electrode tube 3 are coaxially arranged, that is, flow channels 5 are formed all around the lamp tube 1, and the sizes of the flow channels 5 are consistent, which can make full use of the generated ultraviolet light and uniformly irradiate the water in the flow channel 5, so that the treatment effect in the flow channel 5 is basically consistent.

[0028] Exemplarily, the distance between the outer side of the lamp tube 1 and the inner side of the electrode tube 3 is 0.1mm to 10mm, which is a moderate range. If the distance between the outer side of the lamp tube 1 and the inner side of the electrode tube 3 is too small, the flow volume of the flow channel 5 will be too small, resulting in too low treatment efficiency. If the distance between the outer side of the lamp tube 1 and the inner side of the electrode tube 3 is too large, an arc cannot be generated between the electrode tube 3 and the inner electrode 2, and thus ultraviolet light cannot be emitted. It can be understood that the present device is not only used for water treatment, but can also be applied to the treatment of other liquids and even gases. Generally, due to the weak penetration ability of ultraviolet light in liquids, when the present device is used to treat liquids, the distance between the outer side of the lamp tube 1 and the inner side of the electrode tube 3 is small, such as 0.5mm, to ensure the treatment effect; due to the strong penetration ability of ultraviolet light in gases, when the present device is used to treat gases, the distance between the outer side of the lamp tube 1 and the inner side of the electrode tube 3 is large, such as 8mm, to ensure the treatment efficiency.

[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
