[0033] This invention proposes a photon therapy handpiece.

[0034] Combination Figures 2 to 4 As shown, in one embodiment of this utility model, the photon therapy handpiece includes a handpiece body 100 and a light source module 200. The handpiece body 100 includes a housing 110 and a core 120. The core 120 is mounted on the housing 110, and the surface of the housing 110 is provided with a guide portion. The light source module 200 includes a housing assembly 210 and a xenon lamp assembly 220. The xenon lamp assembly 220 is mounted on the housing assembly 210, and the surface of the housing assembly 210 is provided with a mating portion. The guide portion and the mating portion slide together and guide the xenon lamp assembly 220 to be inserted and connected to the core 120.

[0035] The mechanism 120 in the handle body 100 refers to the functional carrier that houses the water pipe connector 121 and the circuit connector 122, etc. The mechanism 120 is located inside the housing 110, making it an assembly that facilitates overall replacement and disassembly. The light source module 200 is a replaceable unit containing the xenon lamp 221 and its auxiliary components. Specifically, it can be a module that encapsulates the xenon lamp 221 and cooling pipes in a high-temperature resistant plastic housing.

[0036] The guide section and mating section refer to the physical structure that guides and positions the handle body 100 and the light source module 200 during assembly. Specifically, it can be a structure using a linear groove 124 and a slide rail 213, or a structure using a guide hole and a guide post. Its extension direction is the same as the direction in which the xenon lamp assembly 220 is inserted into the mechanism 120, to guide the two parts to fit together. The guide section is located on the surface of the housing 110. The mating section is located on the surface of the housing assembly 210.

[0037] Specifically, when replacing the xenon lamp assembly 220, the operator inserts the light source module 200 into the handle body 100 along the sliding engagement direction of the guide and mating parts. The contact surface between the mating part and the guide part generates a lateral constraint force to correct the spatial position of the xenon lamp assembly 220 and the mechanism 120. Here, lateral refers to the direction perpendicular to the insertion of the light source module 200 into the handle body 100. When the light source module 200 reaches the predetermined position, the water pipe plug 223 of the xenon lamp 221 coaxially aligns with the water pipe connector 121 of the mechanism 120, and the circuit plug 222 forms electrical contact with the circuit connector 122. During this process, no manual adjustment of the insertion angle is required; the functional connection with the handle body 100 is completed by guiding the linear movement of the light source assembly through the sliding engagement of the guide and mating parts.

[0038] Compared with existing technologies, traditional solutions require disassembling the outer casing and then separating the connectors one by one. This solution simplifies the complex disassembly and assembly steps into a single linear plug-in operation through modular design and sliding guide mechanism, enabling rapid disassembly and assembly of the xenon lamp assembly 220, improving the user experience and the convenience of component installation and maintenance.

[0039] Combination Figures 2 to 4 As shown, in one embodiment of this utility model, the guide part is a groove 124 and the mating part is a slide rail 213.

[0040] The slide groove 124 can be formed on the surface of the housing 110 by metal cutting or injection molding. The cross-sectional shape of the slide groove 124 can be rectangular, trapezoidal, or dovetail-shaped, and it is used to restrict the movement of the slide rail 213 in directions other than its length extension direction. The protruding shape of the slide rail 213 and the slide groove 124 form a complementary fit.

[0041] Specifically, when the operator pushes the light source module 200 toward the handle body 100, the slide rail 213 is inserted into the inlet end of the slide groove 124 and slides along its extension direction. During the sliding process, the side wall of the slide groove 124 is in continuous contact with the side of the slide rail 213, forcing the light source module 200 to move along a preset trajectory until the water pipe plug 223 and the circuit plug 222 of the xenon lamp assembly 220 are precisely aligned with the corresponding interface of the mechanism 120.

[0042] Compared to existing technologies, traditional assembly methods rely on the operator visually adjusting the insertion position, which carries the risk of axial misalignment leading to interface misalignment. The mating structure of the slide rail 213 and the slide groove 124 provides guidance and constraint, eliminating deviations in the lateral and rotational directions of the light source module 200. This enables rapid positioning and assembly of the light source module 200 and the handle body 100, allowing for precise docking without repeated adjustments to the insertion angle. During maintenance and disassembly, the light source module 200 can be separated by driving the guide and mating parts to slide in opposite directions, offering greater convenience compared to traditional threaded fastening or snap-locking.

[0043] In other embodiments, the guide portion is a slide rail, and the mating portion is a slide groove.

[0044] In one embodiment of the present invention, the end face of the housing 110 is provided with a plug-in hole (not shown), the xenon lamp assembly 220 passes through the plug-in hole and is plugged into the core 120, and the slide groove 124 extends along an acute angle with the end face of the housing 110.

[0045] In this context, the end face of the housing 110 refers to the planar structure on the housing 110 that abuts against the light source assembly, defining the position where the xenon lamp assembly 220 is inserted into the core 120. The insertion hole refers to a through-hole structure penetrating the end face of the housing 110, which can be circular or polygonal. In this embodiment, the extension path of the slide groove 124 forms an inclination angle of less than 90 degrees with the end face of the housing 110, specifically 80 degrees, 85 degrees, etc.

[0046] During assembly, the xenon lamp assembly 220 enters the housing 110 through the insertion hole. Because the slide groove 124 extends at an angle, the xenon lamp assembly 220 also inserts into the housing 120 along this angled direction. This angled insertion method decomposes the insertion force into an axial insertion component and a lateral limiting component, ensuring that the xenon lamp assembly 220 is accurately inserted into the mating position of the housing 120, while also eliminating any lateral offset that may occur during assembly through the lateral component. Simultaneously, this angled insertion method also restricts the separation of the xenon lamp assembly 220 from the housing 120, ensuring a stable connection between the xenon lamp assembly 220 and the housing 120 during daily use.

[0047] In one embodiment of the present invention, along the sliding direction perpendicular to the slide rail 213 relative to the slide groove 124, the widest part of the cross-sectional dimension of the slide rail 213 is not adjacent to the housing assembly 210, and the shape of the slide groove 124 is adapted to the slide rail 213.

[0048] In this embodiment, the slide rail 213 can be configured such that its widest point is not adjacent to the housing assembly 210. For example, along the sliding direction perpendicular to the slide rail 213 relative to the slide groove 124, the slide rail 213 includes two segments: the first segment has a rectangular longitudinal cross-section, and the second segment has a trapezoidal or semi-circular longitudinal cross-section; or the longitudinal cross-section of the slide rail 213 can be configured as an I-shape. Alternatively, the slide rail 213 can be configured such that its cross-sectional dimensions gradually increase or decrease along the sliding direction perpendicular to the slide rail 213 relative to the slide groove 124. For example, the longitudinal cross-sectional shape of the slide rail 213 can be configured as a trapezoid or triangular shape. In this way, the slide rail 213 can only slide into the slide groove 124 along its length. Moreover, after the slide rail 213 is inserted into the slide groove 124, since its widest point is away from the housing assembly 210, the slide rail 213 cannot move towards the housing assembly 210, i.e., it cannot disengage from the slide groove 124 in the vertical direction.

[0049] The aforementioned structural design of the slide rail 213 is intended to ensure that, after the slide rail 213 and the slide groove 124 are in sliding engagement, this structure of the slide rail 213 can form a limiting constraint with the groove wall of the slide groove 124 in the direction perpendicular to its sliding direction, preventing the slide rail 213 and the slide groove 124 from separating in the direction perpendicular to the sliding direction. This, in turn, ensures the assembly and positioning accuracy of the xenon lamp assembly 220 and the core 120.

[0050] In one embodiment of the present invention, the cross-sectional shape of the slide rail 213 is trapezoidal or dovetail-shaped, and the slide groove 124 is adapted to the shape of the slide rail 213.

[0051] The slide rail 213 has a trapezoidal or dovetail-shaped cross-section, meaning that the cross-sectional profile of the slide rail 213 has a geometric feature of being inclined on both sides. The slide groove 124 is adapted to the shape of the slide rail 213, meaning that the geometry of the inner wall of the slide groove 124 matches the outer contour of the slide rail 213, forming a complementary sliding contact surface.

[0052] Trapezoidal or dovetail-shaped slide rails 213 achieve stable connection without additional fixing devices through the mechanical limiting effect generated by their geometric shape, reducing the problem of slippage caused by vibration or improper operation. The trapezoidal or dovetail-shaped cross-section of the slide rail 213 achieves self-locking through geometric limiting, preventing lateral displacement or longitudinal disengagement of components after insertion.

[0053] Combination Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the xenon lamp assembly 220 includes a water pipe plug 223, a circuit plug 222 and a xenon lamp 221, and the mechanism 120 includes a water pipe connector 121, a circuit connector 122 and a fixing base 123.

[0054] The guide is located on the surface of the mounting base 123. The water pipe connector 121 and the circuit connector 122 are both installed on the mounting base 123. The circuit plug 222 is electrically connected to the xenon lamp 221. When the xenon lamp assembly 220 and the mechanism are connected, the circuit plug 222 is plugged into the circuit connector 122, and the water pipe plug 223 is plugged into the water pipe connector 121.

[0055] The water pipe plug 223 and water pipe connector 121 are used to guide the liquid cooling the xenon lamp 221. Furthermore, the surface of the mounting base 123 is provided with a mounting hole 1232 and a mounting groove 1233. The water pipe plug 223 is installed in the mounting groove 1233. One end of the water pipe plug 223 passes through the mounting hole 1232 and extends to the outside of the mounting base 123 for plugging and connecting with the water pipe connector 121.

[0056] The water pipe plug 223 can adopt a quick-plug structure with a sealing ring, which forms a sealed connection by axially inserting into the water pipe connector 121 to prevent liquid leakage. The circuit plug 222 is a conductive interface for supplying power to the xenon lamp 221. Specifically, it can be a metal contact plug, or the circuit plug 222 can be integrated with the xenon lamp 221 and located at one end of the xenon lamp 221. After the circuit plug 222 and the circuit connector 122 are plugged in, a current transmission path is formed to control the light emission of the xenon lamp 221.

[0057] It is fitted around the water pipe plug 223 and locks the water pipe connector 121. The fixing base 123 is the base for installing the water pipe connector 121 and the circuit connector 122. It can be manufactured by injection molding or metal processing. The guide part on its surface is used to guide the xenon lamp assembly 220 to move along a preset trajectory.

[0058] Specifically, the water pipe plug 223 of the xenon lamp assembly 220 forms a sealed connection with the water pipe connector 121 on the mounting base 123, through which cooling liquid flows to cool the xenon lamp 221. After the circuit plug 222 is inserted into the circuit connector 122 of the mounting base 123, the xenon lamp 221 is connected to an external power source. The guide portion, by limiting the movement direction of the xenon lamp assembly 220, ensures that the water pipe plug 223 and connector, and the circuit plug 222 and connector, remain coaxially aligned during insertion, preventing sealing failure or poor contact due to misalignment.

[0059] Both ends of the xenon lamp 221 are provided with circuit plugs 222. The xenon lamp assembly 220 also includes two insulating sleeves 225, which are respectively fitted onto both ends of the xenon lamp 221 and used to fix the xenon lamp 221. A sealing gasket for the xenon lamp 221 is provided between the insulating sleeves 225 and the housing assembly 210 for insulating and sealing the xenon lamp 221 from the internal cooling water. The circuit plugs 222 include a cathode and an anode. An insulating cover 226 is also provided at the end of the xenon lamp 221 away from the water pipe plug 223. The insulating cover 226 is fitted onto the outside of the insulating sleeves 225. A crown spring double-hole socket 227 is installed on the inside of the insulating cover 226. The cathode and anode of the xenon lamp 221 are inserted into the crown spring double-hole socket 227 for series conduction. A sealing ring is provided between the insulating cover 226 and the insulating sleeves 225 for waterproof sealing. In one embodiment, the guide part is a groove 124 and the mating part is a slide rail 213. When the slide rail 213 slides on the groove 124, the circuit plug 222 moves toward the circuit connector 122. When the slide rail 213 slides to the end of the groove 124, the circuit plug 222 is just inserted into the circuit connector 122 to form an electrical connection.

[0060] Furthermore, a crown spring terminal is provided within the circuit connector 122. The circuit plug 222 is inserted into the circuit connector 122 and engages with the crown spring terminal for electrical connection. One end of the circuit connector 122 is an open plug-in end, while the other end is used for connection and fixation to external circuit wires. The crown spring terminal is located within the plug-in end and is connected to the external connection wires extending from the tail of the circuit connector 122 via wire soldering or other methods to achieve electrical connection with the external circuit. The crown spring terminal is made of a flexible metal material (such as copper) and is ring-shaped. Its outer diameter is slightly smaller than the inner diameter of the circuit connector, while the inner diameter is designed according to the size of the corresponding pin of the circuit plug 222 to ensure good contact fit. After the circuit plug 222 is inserted into the plug-in end of the circuit connector 122, the circuit plug 222 compresses the crown spring terminal, causing the crown spring terminal to elastically deform and tightly wrap around the circuit plug 222, thereby achieving a stable electrical connection.

[0061] Combination Figure 2 and Figure 3 As shown, the circuit connector 122 has two plug terminals and two circuit plugs 222, which correspond to the cathode and anode of the xenon lamp 221 respectively. The two circuit plugs 222 are respectively inserted into the two plug terminals of the circuit connector 122 and connected to the crown spring terminal, thereby realizing the electrical connection between the cathode and anode of the xenon lamp 221 and the external circuit.

[0062] Combination Figure 1 and Figure 3As shown, in one embodiment of this utility model, the handle body 100 further includes an unlocking button 131 and a connector 132. The unlocking button 131 is movably disposed on the surface of the housing 110 and is connected to the connector 132 in a transmission manner. When the xenon lamp assembly 220 is plugged into the mechanism 120, the connector 132 is locked to the xenon lamp assembly 220. When the unlocking button 131 is pressed, the unlocking button 131 drives the connector 132 to move, thereby releasing the lock between the connector 132 and the xenon lamp assembly 220.

[0063] The unlock button 131 can be implemented using a spring-loaded reset button or a slider structure, and its movement direction can be a linear motion perpendicular to the surface of the housing 110 or a sliding motion parallel to the housing 110. The connector 132 is a transmission component that transmits the mechanical action of the unlock button 131; specifically, it can be a linkage, a snap-fit ​​push rod, or a snap ring structure. Its connection with the xenon lamp assembly 220 is configured such that the xenon lamp assembly 220 can be locked or unlocked through the displacement of the connector 132. The driving connection between the unlock button 131 and the connector 132 can be achieved through a snap-fit ​​linkage arm, a gear and rack mechanism, or a sloped push structure, ensuring that the pressing action is converted into a linear displacement of the connector 132.

[0064] Specifically, when the unlock button 131 is pressed by an external force, it will push the connector 132 to move along a preset guide path. The displacement of the connector 132 directly acts on the locking part of the xenon lamp assembly 220, such as the retaining ring disengaging from the annular groove of the water pipe plug 223, or the push rod opening the latching structure of the circuit plug 222. During this process, the water pipe connector 121 and the circuit connector 122 between the xenon lamp assembly 220 and the mechanism 120 are released from mechanical locking due to the displacement of the connector 132, thereby allowing the xenon lamp assembly 220 to be pulled out as a whole along the slide rail 213.

[0065] This solution unlocks the connection between the xenon lamp assembly 220 and the mechanism 120 by pressing the unlock button 131 at a single point, achieving one-click separation of the xenon lamp assembly 220. At the same time, the design of the unlock button 131 embedded in the housing 110 maintains the overall sealing of the handle, ensuring that it will not be accidentally unlocked due to accidental touch during treatment.

[0066] Combination Figure 1 and Figure 3 As shown, in one embodiment of this utility model, the connector 132 is a retaining ring, which is sleeved on the outer periphery of the water pipe plug 223 and engages with the water pipe plug 223. The unlocking key 131 abuts against the surface of the retaining ring. Pressing the unlocking key 131 causes the retaining ring to move, so that the retaining ring is separated from the water pipe plug 223.

[0067] In this embodiment, the retaining ring can be made of a metal or plastic material with a certain elasticity. The retaining ring is sleeved on the outer periphery of the water pipe plug 223. For example, an annular groove is provided on the outer periphery of the water pipe plug 223. The inner diameter of the retaining ring is larger than the outer diameter of the water pipe plug 223. The retaining ring is connected to the housing 110 or the core 120 through an elastic element. Under the action of the elastic element, the retaining ring is embedded and locked in the annular groove, forming an axial limit on the water pipe plug 223, that is, restricting the separation of the xenon lamp assembly 220 from the core 120.

[0068] When the unlock button 131 is pressed, the retaining ring moves radially along the water pipe plug 223 to disengage from the annular groove and release the radial lock on the xenon lamp assembly 220. At this time, the xenon lamp assembly 220 can slide away from the mechanism 120 along the guide slide path.

[0069] Combination Figure 4 As shown, in one embodiment of the present invention, the xenon lamp assembly 220 further includes a glass sleeve 224, the housing assembly 210 includes a housing 211 and a fixing block 212, the fixing block 212 is disposed inside the housing 211 and forms a water channel, the glass sleeve 224 is sleeved on the outer periphery of the xenon lamp 221, and the water channel is connected to both the glass sleeve 224 and the water pipe plug 223.

[0070] The glass sleeve 224 is a transparent tubular structure surrounding the outer surface of the xenon lamp 221. It can be made of quartz glass and serves to form a flow channel for the coolant. The transparent glass sleeve 224 also ensures that the light from the xenon lamp 221 can be transmitted unobstructed to the outside of the handle. A fixing block 212 is installed inside the outer casing 211 to form a water channel and fix the glass sleeve 224. The water channel is a continuous, through-flow channel located inside the fixing block 212. It can be molded into a straight or curved path to guide the coolant through the gap between the glass sleeve 224 and the xenon lamp 221. Multiple fixing blocks 212 can be provided and assembled into a single structure. A reflective groove 214 is recessed on one side of the fixing block 212. The glass sleeve 224 and the xenon lamp 221 are installed within the reflective groove 214. The light emitted by the xenon lamp 221 towards the fixing block 212 is reflected by the reflective groove 214 and emitted from the light outlet of the handle.

[0071] The water channels inside the mounting block 212 are directly connected to both ends of the glass sleeve 224. Coolant enters the mounting block 212 through the water pipe plug 223 and flows along the water channels to the glass sleeve 224, forming a circulating cooling path around the xenon lamp 221. The annular gap between the glass sleeve 224 and the xenon lamp 221 allows the coolant to evenly contact the surface of the xenon lamp 221. Simultaneously, the mounting block 212 integrates the water channels internally, avoiding the need for separate pipes on the outside of the housing assembly 210. This solution integrates the water channels in the mounting block 212, embedding the coolant delivery path within the housing assembly 210, reducing the number of external connecting parts. Furthermore, the direct connection between the mounting block 212 and the glass sleeve 224 allows the xenon lamp assembly 220 to be completely disassembled, simplifying maintenance procedures.

[0072] Combination Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the water channel includes an inlet channel 2122 and an outlet channel 2121, there are two water pipe plugs 223, namely an inlet plug 2231 and an outlet plug 2232, and there are two water pipe connectors 121, namely an inlet connector 1212 and an outlet connector 1211.

[0073] The water inlet plug 2231 is connected to the water inlet connector 1212 and the water inlet channel 2122 respectively; the glass sleeve 224 is connected to the water inlet channel 2122 and the water outlet channel 2121 respectively; and the water outlet plug 2232 is connected to the water outlet channel 2121 and the water outlet connector 1211 respectively.

[0074] The cooling water flows sequentially through the inlet connector 1212, the inlet plug 2231, the inlet channel 2122, the glass sleeve 224, the outlet channel 2121, the outlet plug 2232, and the outlet connector 1211.

[0075] The inlet channel 2122 is a flow path located inside the fixed block 212 and connected to the inlet plug 2231, used to guide external coolant into the glass sleeve 224 area. The outlet channel 2121 is a return path independently set from the inlet channel 2122 and connected to the outlet plug 2232, used to discharge the coolant after heat exchange.

[0076] Specifically, when the coolant is injected through the inlet connector 1212, it enters the inlet channel 2122 within the fixed block 212 via the inlet plug 2231, and flows along a predetermined path to the glass sleeve 224. During the operation of the xenon lamp 221, the coolant envelops the xenon lamp 221 and absorbs heat, then enters the outlet plug 2232 through the outlet channel 2121, and finally returns to the cooling system via the outlet connector 1211. This flow path forms a unidirectional closed loop through the spatially separated inlet / outlet channels 2121, improving the cooling effect on the xenon lamp 221. The inlet plug 2231 and the outlet plug 2232 have a leak-proof shut-off valve function to improve the sealing effect.

[0077] Combination Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment of the present invention, the surface of the fixed base 123 is provided with a light-transmitting hole 1231, and the mechanism 120 also includes a light guide lens 310, which is installed in the light-transmitting hole 1231.

[0078] The mechanism 120 includes a lens assembly 300, which includes a light guide lens 310 and two clamping plates 320. The two clamping plates 320 are clamped on both sides of the light guide lens 310 and are used to fix the light guide lens 310. The surface of the fixing base 123 is also provided with a connecting hole 1234, and the surface of the clamping plate 320 is provided with a threaded hole 321. The fixing base 123 and the clamping plate 320 are fixedly connected by a threaded connector 132 passing through the connecting hole 1234 and the threaded hole 321, thereby installing the light guide lens 310 in the light transmission hole 1231.

[0079] The light-transmitting aperture 1231 allows light emitted from the xenon lamp 221 to pass through, and can be a circular or rectangular opening. The light-guiding lens 310 is an optical element used to guide light in a specific direction, and can be made of sapphire or quartz glass. The function of the light-guiding lens 310 is to guide the light emitted from the xenon lamp 221 through the light-transmitting aperture 1231 and onto the skin, reducing heat dissipation and leakage of light, and improving the treatment effect.

[0080] Specifically, the light generated by the xenon lamp 221 is directly transmitted to the light guide lens 310 through the light-transmitting hole 1231, and the light guide lens 310 and the xenon lamp assembly 220 are spatially isolated by the mounting base 123. When it is necessary to disassemble or replace the xenon lamp 221, the xenon lamp assembly 220 only needs to be moved along the mating direction of the slide rail 213 and the slide groove 124, without removing the light guide lens 310. Since the light guide lens 310 is fixed on the other side of the mounting base 123 and has no direct connection with the xenon lamp 221, the insertion and removal of the xenon lamp assembly 220 will not affect the installation status of the light guide lens 310, thus simplifying the maintenance steps.

[0081] In one embodiment of this utility model, the light guide lens 310 is arranged opposite to the xenon lamp 221, and the projection of the xenon lamp 221 toward the light guide lens 310 is located within the area of ​​the light guide lens 310.

[0082] In this embodiment, the light guide lens 310 is positioned directly opposite the xenon lamp 221 to improve the light guiding effect of the light guide lens 310 on the light from the xenon lamp 221. At the same time, the projection of the xenon lamp 221 toward the light guide lens 310 is located within the area of ​​the light guide lens 310, that is, the area of ​​the light guide lens 310 is larger than the area of ​​the xenon lamp 221, in order to reduce light leakage and allow as much of the light energy emitted by the xenon lamp 221 as possible to be guided by the light guide lens 310 and act on the skin, thereby increasing the light guiding efficiency.

[0083] Furthermore, the area of ​​the light guide lens 310 is larger than that of the glass sleeve 224 surrounding the xenon lamp 221. The light emitted by the xenon lamp 221 through the glass sleeve 224 can be guided by the light guide lens 310 to act on the skin as much as possible, thereby further reducing light leakage and improving the light guiding efficiency of the light guide lens 310.

[0084] Furthermore, the xenon lamp 221 and the light guide lens 310 are fitted with a gap to facilitate the installation and mating of the xenon lamp assembly 220 and the light guide lens 310. Simultaneously, the small gap between the xenon lamp 221 and the light guide lens 310 reduces scattering of the xenon lamp 221 towards the outside of the light guide lens 310, thereby allowing the light emitted by the xenon lamp 221 to be guided by the light guide lens 310 and applied to the skin as much as possible.

[0085] This utility model also proposes a photon therapy device, which includes a main unit 400 and a photon therapy handle. The specific structure of the photon therapy handle is as described in the above embodiments. Since the photon therapy device adopts all the technical solutions of all the above embodiments of the photon therapy handle, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0086] Among them, combined Figure 1 As shown, the main unit 400 is electrically connected to the photon therapy handpiece. The main unit 400 refers to the control unit, which can specifically be a device with data processing and power supply functions, used to regulate treatment parameters and maintain system operation. A handpiece plug 500 is provided on one side of the main unit 400, and it is connected to the photon therapy handpiece via a cable for communication, so as to exchange working status data in real time and send control commands.

[0087] The guide and mating parts of the photon therapy handpiece guide the xenon lamp assembly 220 to precisely connect with the mechanism 120 via a sliding trajectory. After the unlock button 131 and the linkage connector 132 are released from the locked state, the xenon lamp assembly 220 can be separated along a preset path. The host 400 obtains the power and temperature data of the xenon lamp 221 in real time through a communication connection and dynamically adjusts the output parameters. When the xenon lamp 221 needs to be replaced, simply press the unlock button 131 and pull the xenon lamp assembly 220 away along the slide rail 213 without disassembling other related components. This achieves quick replacement of the xenon lamp assembly 220, reduces intervention in the overall structure during maintenance, shortens repair time, and reduces operational complexity. At the same time, it ensures that the photon therapy device can maintain its original energy output accuracy and cooling system reliability after maintenance.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
