[0034] like Figure 1 and Figure 2 As shown, the integrated X-ray source device provided by this utility model includes a housing 100, an X-ray emitter 200, a power supply circuit 300, an isolation cover 400, and a protective component 500. Specifically, the X-ray emitter 200, the power supply circuit 300, and the isolation cover 400 are all installed inside the housing 100, wherein the isolation cover 400 is used to isolate the X-ray emitter 200 from the power supply circuit 300; the housing 100 is provided with... Figure 3The X-ray emitter 200 is provided with an emission window 210 adapted to be connected to the mounting window 101, and the protective member 500 is installed on the outside of the housing 100 to completely cover the mounting window 101 and the emission window 210, and to allow X-rays emitted by the X-ray emitter 200 through the emission window 210 to pass through.

[0035] In one specific embodiment, the power supply circuit 300 is configured according to... Figure 2 The X-ray emitter 200 is positioned at the back side of the X-ray emitter 200, and an isolation gap 301 is formed between the back side of the X-ray emitter 200 and the power circuit 300 to achieve initial isolation between the X-ray emitter 200 and the power circuit 300. At the same time, the housing 100 is filled with an insulating refrigerant (such as cooling oil) that acts on the X-ray emitter 200. The isolation gap 301 is also used to allow the flow of the insulating refrigerant to achieve integrated cooling of the X-ray emitter 200 and the power circuit 300.

[0036] In this embodiment, the power supply circuit 300 supplies power to the X-ray emitter 200, thus creating a high-voltage zone on the back side of the X-ray emitter 200. The isolation shield 400 is positioned between the X-ray emitter 200 and the power supply circuit 300 to further enhance the isolation effect between them. In a typical implementation, the isolation shield 400 covers the exterior of the X-ray emitter 200 and extends from the back side to the front side, thereby creating a structure where the rear wall thickness of the X-ray emitter 200 is greater than the front wall thickness. This ensures effective isolation while reducing the space occupied by each structure, achieving integrated assembly of the overall structure.

[0037] In one specific embodiment, the X-ray emitter 200 includes, as shown below: Figure 5 The shielding barrel 230 shown and the X-ray tube 240 installed inside the shielding barrel 230 are shown. The isolation cover 400 covers the outside of the shielding barrel 230, that is, the shielding barrel 230 has a structure in which the rear wall thickness is greater than the front wall thickness.

[0038] Specifically, such as Figure 4 and Figure 5As shown, a first end cap 231 and a second end cap 232 are respectively installed at both ends of the shielding barrel 230. The two ends of the X-ray tube 240 are respectively installed inside the first end cap 231 and the second end cap 232, thereby achieving stable installation of the X-ray tube 240. The first end cap 231 and the second end cap 232 are made of lead oxide material, which ensures shielding and insulation performance, meets creepage distance requirements, and allows the power supply circuit 300 to be housed within the outer casing 100, thus achieving an integrated oil-cooling design.

[0039] like Figure 5 As shown, the shielding barrel 230 has a first mounting platform 233 and a second mounting platform 234 at both ends, a first docking platform 237 on the first end cover 231, and a second docking platform 238 on the second end cover 232. For example, both the first mounting platform 233 and the second mounting platform 234 are configured with an inner ring structure whose outer diameter is smaller than that of the shielding barrel 230; the first docking platform 237 is configured with an outer ring structure whose inner diameter matches the outer diameter of the first mounting platform 233, so that when the first end cap 231 is installed on one end of the shielding barrel 230 through the matching docking of the first mounting platform 233 and the first docking platform 237, the first docking platform 237 is sleeved on the outside of the first mounting platform 233; the second docking platform 238 is configured with an outer ring structure whose inner diameter matches the outer diameter of the second mounting platform 234, so that when the second end cap 232 is installed on the other end of the shielding barrel 230 through the matching docking of the second mounting platform 234 and the second docking platform 238, the second docking platform 238 is sleeved on the outside of the second mounting platform 234. Based on this structural design, on the one hand, it facilitates the production and processing of the shielding barrel 230 and the first end cap 231 and the second end cap 232; on the other hand, it facilitates the assembly of the shielding barrel 230 with the first end cap 231 and the second end cap 232. In addition, based on the overlapping of the mounting platform and the docking platform, it can effectively prevent the X-rays emitted by the X-ray tube 240 from leaking out from the connection between the shielding barrel 230 and the end cap, thereby further improving the overall shielding performance of the shielding barrel 230 and the end cap.

[0040] To further improve radiation shielding and facilitate the power connection of the X-ray tube 240, a first through hole 235 is provided on the peripheral wall of the first end cover 231, and a second through hole 236 is provided on the peripheral wall of the second end cover 232. Figure 5As shown, the central axes of the first through-hole 235 and the second through-hole 236 are both inclined relative to the central axis of the shielding barrel 230. The power supply circuit 300 is electrically connected to the X-ray emitter 200 through a power connection line 302 passing through the first through-hole 235 and the second through-hole 236. The inclination of the first through-hole 235 and the second through-hole 236 prevents X-rays emitted from the X-ray tube 240 from directly passing through the through-holes, effectively preventing lateral X-ray leakage. Simultaneously, the through-hole structure also makes the installation of the power connection line 302 more convenient.

[0041] In one specific embodiment, reference is made to Figure 5 As shown, the X-ray tube 240 includes a tube body 241 and an anode 242 that is fixed through one end of the tube body 241, such that both ends of the anode 242 are exposed in the shielding barrel 230 and enclosed in the tube body 241, respectively; wherein, the anode 242 is electrically connected to the power supply circuit 300 through the end exposed in the shielding barrel 230.

[0042] In this embodiment, as Figure 4 and Figure 6 As shown, the shielding barrel 230 is provided with an isolation window 211 opposite to one end of the anode 242 enclosing the tube body 241. The isolation window 211 is made of lead oxide material and has a hollow structure. A glass window 212 is installed inside the hollow of the isolation window 211. The isolation window 211 and the glass window 212 are combined to form an emission window 210 that guides the X-ray tube 240 out. The outer shell 100 is provided with an installation window 101 that mates with the emission window 210. The X-ray emitter 200 is installed inside the outer shell 100 by mates the emission window 210 with the installation window 101. Specifically, the emission window 210 is located on the front side of the shielding barrel 230 to further improve the radiation shielding effect through reasonable structural arrangement and isolation of the isolation window 211.

[0043] It is worth noting that when the ejection window 210 aligns with the mounting window 101, the hollow coaxial portion of the isolation window 211 is aligned with the mounting window 101, and a space is provided between the isolation window 211 and the outer casing 100 as follows: Figure 6 The sealing gasket 220 shown is used to enclose the hollow exterior. For example... Figure 4 As shown, the isolation window 211 has a sealing groove 213 at its end, and the sealing gasket 220 between the isolation window 211 and the outer shell 100 is at least partially embedded in the sealing groove 213, thereby effectively improving the insulation performance between the isolation window 211 and the outer shell 100.

[0044] In one specific embodiment, reference is made to Figure 7 As shown, the protective component 500 includes a connecting flange 501 and a light-transmitting protective plate 502 fixed to the outside of the housing 100 via the connecting flange 501. The connecting flange 501 is coaxially fitted to the outside of the mounting window 101 so that the light-transmitting protective plate 502 completely covers the mounting window 101, thereby achieving the effect of protecting the mounting window 101 and the ejection window 210 from impact damage.

[0045] In summary, this utility model provides an integrated X-ray source device, and a new shielding barrel 230 and isolation window 211 made of lead oxide material are designed to facilitate the assembly of the X-ray tube 240, while meeting the requirements of integrated oil cooling, structural insulation, and radiation shielding. In addition, a protective component 500 is provided to protect the radiation emission window 210 to avoid damage to the window.
