[0031] Please refer to Figures 1 to 3 The utility model provides a kind of pulse xenon lamp 100, pulse xenon lamp 100 includes shell 1, electrode structure 2 and temperature sensor 3, shell 1 is equipped with cavity 13;Electrode structure 2 includes electrode head 23, electrode head 23 at least part extends into cavity 13 and is enclosed with shell 1 to form the gas cavity 4 for accommodating xenon, electrode structure 2 is provided with mounting cavity 221 at one end away from cavity 13;Temperature sensor 3 is located in mounting cavity 221.

[0032] It can be understood that electrode structure 2 is connected to shell 1, and is enclosed with shell 1 to form a closed gas cavity 4, which is filled with xenon; Specifically, one end of electrode head 23 extends to the opening of cavity 13 to plug the cavity 13, so that the cavity 13 is a closed space, i.e. the gas cavity 4; In some embodiments, the electrode head 23 cannot completely plug the opening of the cavity 13, and the other components of the electrode structure 2 cooperate with the electrode head 23 to plug the opening of the cavity 13. Generally, the number of electrode heads 23 is two, the shell 1 is a hollow tube, i.e. the cavity 13 has two openings, and the two electrode heads 23 are arranged at the two openings to form a xenon lamp. The electrode head 23 generates high-voltage pulse to break down the xenon, so that the xenon ionizes to generate a large number of charged particles, which accelerate under the action of the electric field and collide with xenon atoms and molecules, causing the xenon atoms and molecules to transition to high energy levels. When the xenon atoms and molecules transition from high energy levels to low energy levels, they release energy in the form of photons, thereby generating light radiation. When the electrode head 23 discharges, the end in direct contact with the plasma usually has the highest temperature. At the same time, the other end of the electrode structure 2, i.e. the end away from the electrode head 23, is provided with a mounting cavity 221 for mounting a temperature sensor 3, and the temperature sensor 3 is used to detect the temperature of the electrode head 23 to provide corresponding heat dissipation mode or heat dissipation speed in time according to the temperature of the electrode head 23.

[0033] In the embodiment, the electrode head 23 of the electrode structure 2 is directed towards the gas-containing cavity 4, and the temperature sensor 3 is arranged in the mounting cavity 221 of the electrode structure 2. When the electrode head 23 discharges, the temperature sensor 3 can detect the real-time temperature of the electrode head 23 to warn the user, so as to avoid continuous discharge of the electrode head 23 to cause over-temperature, reduce the service life and discharge effect of the electrode structure 2, and even cause danger to the user.

[0034] In actual implementation, the mounting cavity 221 is arranged to extend towards the electrode head 23, so that the temperature sensor 3 is arranged as close to the electrode head 23 as possible, and the accuracy and precision of the temperature sensor 3 in detecting the temperature of the electrode head 23 are improved.

[0035] Optionally, the shell 1 is tubular and both ends are through, and two electrode structures 2 can be arranged at the two ends respectively, and one end of the electrode structure 2 provided with the electrode head 23 extends into the containing cavity 13.

[0036] Optionally, the electrode structure 2 and the temperature sensor 3 can be electrically connected with a control device, and the control device can control the on-off of the electrode structure 2. The user can set a threshold of the temperature detected by the temperature sensor 3 to the control device, and when the working temperature of the electrode head 23 detected by the temperature sensor 3 exceeds the threshold, the control device can automatically control the electrode structure 2 to be powered off, so as to ensure the safety of the use of the pulse xenon lamp 100.

[0037] In an embodiment of the utility model, as shown in Figures 1 to 3 The electrode structure 2 comprises a conductive part 21 and an insulating and heat-conducting part 22, the conductive part 21 is connected to the shell 1, the electrode head 23 is connected to the conductive part 21, the conductive part 21 is provided with a placing cavity 211, the insulating and heat-conducting part 22 is arranged in the placing cavity 211 and closely arranged on the cavity wall of the placing cavity 211, and the insulating and heat-conducting part 22 is provided with a mounting cavity 221.

[0038] In the embodiment, the conductive part 21 is used to electrically connect an external circuit with the electrode head 23 to transmit voltage to the electrode head 23, and the conductive part 21 is provided with the placing cavity 211 for accommodating the insulating and heat-conducting part 22. When the electrode structure 2 is powered on, the inner wall of the placing cavity 211 is electrified. In order to ensure the normal use of the temperature sensor 3, the temperature sensor 3 is arranged in the mounting cavity 221 of the insulating and heat-conducting part 22, and the insulating and heat-conducting part 22 separates the temperature sensor 3 from the conductive part 21, so as to avoid the temperature sensor 3 from being damaged by high voltage and unable to normally operate. The insulating and heat-conducting part 22 also has high heat conductivity, can efficiently transmit the heat on the conductive part 21 to the placing cavity 211, and the temperature sensor 3 can indirectly detect the temperature of the electrode structure 2.

[0039] The insulating and heat-conducting member 22 is arranged close to the cavity wall of the placing cavity 211, and the heat transfer efficiency can be further improved.

[0040] In actual implementation, the temperature sensor 3 comprises a temperature probe and a lead wire, the placing cavity 211 is in communication with the outside, the temperature probe is arranged in the placing cavity 211, and the lead wire is connected to the temperature probe and extends out of the placing cavity 211 to be connected to the control device outside, so that the signal connection and the electrical connection between the temperature probe and the control device are realized, and the control device can receive the temperature signal of the temperature probe and can also supply power to the temperature probe. Optionally, the temperature probe can be a metal bare type probe, and a DC 1000V insulation voltage line body is adopted. The insulating and heat-conducting member 22 is arranged in a hollow mode to form the mounting cavity 221.

[0041] In the embodiment, the electrically conductive member 21 is connected to the shell 1, and the electrode head 23 can be arranged in a spaced mode with the shell 1, so that the electrode head 23 can better discharge to the xenon gas.

[0042] In the embodiment of the utility model, the mounting cavity is in a strip shape, the length direction of the mounting cavity is the same as the length direction of the cavity, and the probe of the temperature sensor is located at the bottom of the mounting cavity.

[0043] Referring to Figure 3 In the embodiment, the mounting cavity 221 is in a strip shape, two ends of the mounting cavity 221 are respectively an opening and a bottom, the bottom is close to the placing cavity 211, the probe is located at the bottom of the mounting cavity 221, and preferably abuts against the bottom of the mounting cavity 221, so that the electrode head 23, the placing cavity 211, the bottom of the mounting cavity 221 and the probe abut in sequence, the temperature at the electrode head 23 is rapidly transmitted to the probe along the electrically conductive member 21 and the insulating and heat-conducting member 22 which have good heat conductivity, and the probe can quickly and accurately collect the temperature at the electrode head 23. Since the mounting cavity 221 is in a strip shape, the bottom of the mounting cavity 221 is as close as possible to the electrode head 23, the area of the bottom of the mounting cavity 221 is small, the heat of the electrode head is as much as possible to be concentrated on the bottom and not to be diffused when reaching the mounting cavity, and the heat can be conducted to the probe with high efficiency, so that the temperature at the probe is highly synchronized with the temperature of the electrode head 23.

[0044] In the embodiment of the utility model, the shape of the bottom of the mounting cavity is matched with the shape of the probe.

[0045] In the embodiment, the adaptation means that the probe can be put into the bottom of the mounting cavity, and the shape of the bottom is just suitable for accommodating the probe, or the bottom just abuts against the outer part of the probe.For example, the probe is in a substantially cylindrical shape, and the bottom of the mounting cavity is in a cylindrical shape, so that the probe can be put into the bottom of the mounting cavity with little extra space.This makes the heat of the electrode tip be conducted to the mounting cavity, and the probe can be wrapped and cannot flow due to the large space, so that the efficiency of the heat of the electrode tip being transferred to the probe is improved, and the temperature sensor can collect the temperature of the electrode tip more accurately.In some other embodiments, the bottom of the mounting cavity can also be in other shapes such as a water drop shape, so as to accommodate the probe and make the space be relatively closed, so that the heat of the electrode tip is not easy to diffuse and move after being conducted to the mounting cavity.

[0046] In an embodiment of the utility model, as shown in Figure 2 and Figure 3 , one end of the conductive part 21 extending into the cavity 13 is provided with a threaded hole 212, and the electrode tip 23 is threadedly connected with the threaded hole 212.

[0047] In the embodiment, the conductive part 21 serves as the main structure of the electrode structure 2, and is connected with the electrode tip 23 through thread cooperation, so that when the electrode tip 23 is worn or damaged due to ionization, the electrode tip 23 can be conveniently and quickly replaced without replacing the entire electrode structure 2, thereby reducing the replacement cost and the use cost of the pulse laser xenon lamp.The insulating and heat-conducting part 22 is arranged in the placing cavity 211 of the conductive part 21, so that when the electrode tip 23 is replaced, the positions of the temperature sensor 3 and the insulating and heat-conducting part 22 relative to the conductive part 21 do not need to be changed, and the replacement convenience of the electrode tip 23 is improved.

[0048] Optionally, there is a certain gap between the electrode tip 23 and the cavity wall of the gas-containing cavity 4, so that the stability of the discharge of the electrode tip 23 can be effectively improved, and at the same time, the gap can also avoid the direct contact between the electrode tip 23 and the cavity wall of the gas-containing cavity 4, thereby reducing the mechanical wear of the electrode tip 23.

[0049] In actual implementation, the diameter of the electrode tip 23 is not greater than the diameter of the threaded hole 212, so that the gap is formed between the electrode tip 23 and the cavity wall of the gas-containing cavity 4.

[0050] In an embodiment of the utility model, as shown in Figures 1 to 3 , the electrode structure 2 further comprises a buffer sleeve 25, the buffer sleeve 25 is connected to the shell 1 and is arranged between the shell 1 and the conductive part 21, and the buffer sleeve 25 is used for buffering the thermal expansion between the conductive part 21 and the shell 1.

[0051] In the embodiment, the conductive piece 21 expands after being electrified and heated, and the expansion amount of the conductive piece 21 is greater than the expansion amount of the shell 1. In order to avoid that the conductive piece 21 expands and breaks the shell 1, a buffer sleeve 25 is arranged between the shell 1 and the conductive piece 21. The thermal expansion coefficient of the buffer sleeve 25 is greater than the thermal expansion coefficient of the shell 1 and less than the thermal expansion coefficient of the conductive piece 21. In this way, the buffer sleeve 25 plays a transition effect between the shell 1 and the conductive piece 21, so as to compensate for the thermal expansion difference between the conductive piece 21 and the shell 1, and improve the stability of the overall structure of the pulse xenon lamp 100.

[0052] In actual implementation, the buffer sleeve 25 is hollow and is sleeved on the outer periphery of the conductive piece 21. The buffer sleeve 25 can be limited on the inner side of the shell 1 through a limiting groove structure, or is bonded on the inner side of the shell 1, which is not limited here.

[0053] Optionally, the buffer sleeve 25 is detachably connected with the conductive piece 21. The inner side of the buffer sleeve 25 is formed with a threaded hole, and the outer periphery of the conductive piece 21 is provided with a thread. The conductive piece 21 and the buffer sleeve 25 are screwed.

[0054] In an embodiment of the utility model, as shown in Figure 1 and Figure 2 The shell 1 includes a light transmission section 11 and a mounting section 12 arranged at the end of the light transmission section 11. The buffer sleeve 25 is connected to the mounting section 12, and the conductive piece 21 is connected to the buffer sleeve 25.

[0055] In the embodiment, the mounting section 12 is used for mounting the buffer sleeve 25 and the conductive piece 21, and also plays a cooling effect on the conductive piece 21. The light transmission section 11 is used for transmitting the light emitted by the ionization of xenon gas to the outside of the gas cavity 4, so as to treat the patient.

[0056] It can be understood that the shell 1 is segmented, which can meet different setting requirements. The light transmission section 11 has high light transmission rate to ensure the light transmission effect. The mounting section 12 has good mechanical strength and thermal conductivity to ensure the mounting stability and heat dissipation effect of the conductive piece 21.

[0057] In actual implementation, the material of the light transmission section 11 is light transmission glass, and the material of the mounting section 12 is high-thermal-conductivity silicon oxide ceramic, which is not limited here. The light transmission glass has high light transmission rate, can efficiently transmit light, and can maintain stable optical performance in high-temperature and strong-light environment without obvious decrease in optical performance, which can well adapt to the high temperature generated when the xenon lamp emits light. The high-thermal-conductivity silicon oxide ceramic has high thermal conductivity, which is beneficial to heat dissipation of the conductive piece 21. Meanwhile, the ceramic has high strength and high hardness, can bear certain mechanical stress, is suitable for mounting of the conductive piece 21, and has good insulation performance to avoid electric leakage of the conductive piece 21.

[0058] Optionally, the light-transmitting section 11 and the mounting section 12 are connected by welding, and the welding material is silver-based welding filler material, which has good corrosion resistance and gap filling capacity, so as to ensure the connection strength of the light-transmitting section 11 and the mounting section 12.

[0059] In an embodiment of the utility model, as shown in Figure 2 and Figure 3 The material of the conductive part 21 and / or the electrode head 23 is tungsten or tungsten alloy. Tungsten has a high melting point and high temperature stability, so that the conductive part 21 and the electrode head 23 can still maintain stable physical properties and chemical properties in a high temperature environment and are not easy to melt or deform. The material of the buffer sleeve 25 is molybdenum, and the thermal expansion coefficient of molybdenum is between that of tungsten alloy and silicon oxide ceramic, which can play a good buffering role. At the same time, molybdenum also has good high temperature stability, high mechanical strength and thermal conductivity, which can provide a stable mounting structure for the conductive part 21, effectively transfer the heat of the conductive part 21, and improve the heat dissipation effect of the conductive part 21.

[0060] In an embodiment of the utility model, the material of the insulating and heat-conducting part 22 is high-thermal-conductivity silicon oxide ceramic. Silicon oxide ceramic has excellent insulation performance to ensure the stability of the operation of the temperature sensor 3 and avoid damage of the temperature sensor 3 caused by high voltage breakdown. At the same time, high-thermal-conductivity silicon oxide ceramic also has high thermal conductivity, which can transfer the temperature of the conductive part 21 to the temperature sensor 3, so that the temperature sensor 3 can accurately detect the temperature of the conductive part 21.

[0061] In an embodiment of the utility model, as shown in Figures 1 to 3 The electrode structure 2 is provided with a gas supply channel 24 communicating with the gas-containing cavity 4, which is used for supplying xenon gas into the gas-containing cavity 4. The gas inlet 241 of the gas supply channel 24 is arranged at the part of the electrode structure 2 extending out of the cavity 13, and the gas outlet 242 of the gas supply channel 24 is arranged at the outer periphery of the electrode head 23.

[0062] It can be understood that after the pulse xenon lamp 100 is used for a long time, the xenon gas in the gas-containing cavity 4 will gradually leak, which will cause the light energy of the xenon lamp to attenuate and affect the treatment effect of the pulse xenon lamp 100. The gas supply channel 24 can continuously and stably supply xenon gas into the gas-containing cavity 4. The gas inlet 241 of the gas supply channel 24 can be connected to a gas source, and the gas outlet 242 of the gas supply channel 24 communicates with the gas-containing cavity 4, so as to supplement the xenon gas in the gas-containing cavity 4 and prolong the service life of the pulse xenon lamp 100.

[0063] In actual implementation, the gas supply channel 24 is arranged inside the conductive member 21 and the electrode head 23, the gas inlet 241 of the gas supply channel 24 is arranged at the part of the conductive member 21 extending out of the cavity 13, so as to be connected to an external xenon storage container, and the gas outlet 242 of the gas supply channel 24 is arranged on the electrode head 23, so as to supply gas into the gas cavity 4. In this way, the gas supply structure can be avoided to be added on the pulse xenon lamp 100, and the possibility of xenon leakage during transmission can be reduced. The gas supply channel 24 can also be used to transmit the xenon in the gas cavity 4 out of the gas cavity 4, so as to replace the xenon in the gas cavity 4.

[0064] The gas outlet 242 of the gas supply channel 24 can be arranged on the end surface of the electrode head 23, or can be arranged on the side surface of the electrode head 23. In an embodiment, the gas outlet 242 is arranged on the side surface of the electrode head 23, so as to reduce the interference with the discharge of the electrode head 23.

[0065] In an embodiment of the utility model, as shown in Figures 1 to 3 The electrode structure 2 is further provided with a valve hole 243 communicating with the gas supply channel 24, the valve hole 243 is located between the gas inlet 241 and the gas outlet 242, and the pulse xenon lamp 100 further comprises a plugging assembly 5, which is detachably arranged in the valve hole 243 and extends into the gas supply channel 24, and is used for plugging the gas supply channel 24.

[0066] In the embodiment, the valve hole 243 is arranged between the gas inlet 241 and the gas outlet 242, the gas inlet 241 can be continuously communicated with an external xenon storage container, and the user can extend or pull out the plugging assembly 5 into or out of the gas supply channel 24 through the valve hole 243, so as to realize the plugging or communication between the gas inlet 241 and the gas outlet 242, and then pause or start the gas supply to the gas cavity 4.

[0067] In actual implementation, the valve hole 243 is arranged at the part of the electrode structure 2 extending out of the cavity 13, and the plugging assembly 5 can be detachably arranged in the valve hole 243 through a clamping structure or a threaded structure.

[0069] In the embodiment, the sealing ring 52 is connected to the connecting piece 51 near one end of the air supply channel 24, when the connecting piece 51 extends into the air supply channel 24 through the valve hole 243, the sealing ring 52 enters the air supply channel 24 and overlaps with the cross section of the air supply channel 24, and abuts with the hole wall of the valve hole 243, so as to block the air supply channel 24, when the connecting piece 51 is screwed with the valve hole 243, the detachable connection of the connecting piece 51 and the valve hole 243 is realized, the user tightens or loosens the connecting piece 51, and then drives the sealing ring 52 to enter or leave the air supply channel 24, so as to realize the blocking or communication of the air supply channel 24.

[0070] In actual implementation, the connecting piece 51 is provided with a limiting groove near one end of the air supply channel 24, and the sealing ring 52 is limited in the limiting groove, so as to realize the detachable connection of the sealing ring 52, and facilitate the replacement of the sealing ring 52 after aging or damage.
