Description

Technical Field

[0001] The utility model relates to the technical field of X-ray detection, in particular to an X-ray emitter. Background Art

[0002] X-ray sources consist of electrons emitted from a cathode. After being accelerated by the electric field between the cathode and anode, they strike an X-ray anode target, transferring their kinetic energy to atoms on the target. Approximately 1% of this energy is converted into X-rays, which are emitted through the X-ray irradiation window. Due to their high energy and strong penetrating power, X-rays are widely used in security inspections, healthcare, and industrial imaging.

[0032] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0033] like Figure 1-8As shown, an embodiment of the present invention provides an X-ray emitter 300 , comprising: an X-ray shielding barrel 310 , an X-ray tube 380 , and an emission window composed of an isolation piece 350 and a beryllium window 340 .

[0034] A window 370 is formed through the outer wall of the X-ray shielding barrel 310 to facilitate X-ray emission from an X-ray tube 380. The X-ray tube 380 is mounted within the X-ray shielding barrel 310. Specifically, a first end cap 320 is mounted on a first side of the X-ray shielding barrel 310. A first mounting portion 322 is disposed within the inner side of the first end cap 320. One end of the X-ray tube 380 is mounted on the first mounting portion 322.

[0035] A second end cover 330 is installed on the second side of the X-ray shielding barrel 310 . A second mounting portion 333 is provided inside the second end cover 330 . The other end of the X-ray tube 380 is mounted on the second mounting portion 333 , thereby achieving the installation of the X-ray tube 380 .

[0036] Among them, the first end cover 320 and the second end cover 330 are both made of lead tetroxide material instead of the lead material in the prior art. This material and structural design, on the one hand, facilitates the production and processing of the end covers, and on the other hand, can improve the insulation performance, facilitate the installation of the X-ray tube 380, and improve the insulation protection performance between the X-ray tube 380 and the device housing.

[0037] A first through hole 323 is axially formed through the first end cap 320. A first protective cover 321 is mounted on the outside of the first end cap 320 to cover the first through hole 323. The first protective cover 321 is provided with a first channel vertically connected to the first through hole 323. The first through hole 323 passes through the first mounting portion 322. The tube power supply wiring 381 passes through the first channel and the first through hole 323 in sequence and is connected to the power input terminal of the X-ray tube 380. Some radiation may also be emitted from the axial ends of the X-ray tube, posing a risk of leakage through the first through hole 323. Therefore, in this embodiment, a first protective cover 321 is mounted on the outside of the first end cap 320 to cover the first through hole 323 to prevent lateral radiation leakage. By providing a first channel vertically connected to the first through hole 323, radiation shielding can be achieved while also allowing for the routing of the tube power supply wiring.

[0038] Similarly, a second through hole 334 is axially formed through the second end cap 330. A second protective cover is mounted on the outside of the second end cap 330 to cover the second through hole 334. The second protective cover is provided with a second channel that is in vertical communication with the second through hole 334. The second through hole 334 extends through the second mounting portion 333. The DC high-voltage power supply wiring 382 passes through the second channel and the second through hole 334 in sequence and is connected to the high-voltage power supply input of the X-ray tube 380. Similarly, some radiation may also be emitted from the axial ends of the X-ray tube, posing a risk of leakage through the second through hole 334. Therefore, in this embodiment, a second protective cover is mounted on the outside of the second end cap 330 to cover the second through hole 334 to prevent lateral radiation leakage. By providing a second channel that is in vertical communication with the second through hole 334, radiation shielding can be achieved while simultaneously routing the DC high-voltage power supply.

[0039] To further enhance radiation shielding, a first protective retaining ring 325 is provided on the outer periphery of the first mounting portion 322. The first protective retaining ring 325 is embedded in the X-ray shielding barrel 310 to cover one axial side of the X-ray tube 380. Similarly, a second protective retaining ring 335 is provided on the outer periphery of the second mounting portion 333. The second protective retaining ring 335 is embedded in the X-ray shielding barrel 310 to cover the other axial side of the X-ray tube 380. The window 370 in the center of the X-ray shielding barrel 310 is covered by the spacer 350, thereby forming a second radiation shielding layer that complements the X-ray shielding barrel 310 and reduces the risk of radiation leakage from the X-ray emitter.

[0040] A first window 352 is provided through the isolating member 350 for emitting X-rays. The isolating member 350 is mounted on the window 370. Specifically, a mounting platform 351 is provided at the bottom of the isolating member 350. The first window 352 passes through the mounting platform 351. The outer periphery of the beryllium window 340 is sealed and mounted on the mounting platform 351 through an integrally provided abutment platform 341. The beryllium window 340 and the mounting platform 351 are embedded in the window 370, so that the first window 352 corresponds to the ray exit port of the X-ray tube 380 through the beryllium window 340, forming a ray emission window.

[0041] A first mounting seat 371 is provided on the X-ray shielding barrel 310 around the window 370, and a second mounting seat 353 is provided on the isolation member 350 around the mounting platform 351. The isolation member 350 is installed on the first mounting seat 371 through the second mounting seat 353 to cover the window 370 area.

[0042] The isolation member 350 is made of lead tetroxide material to cover the window 370 to play a shielding role and improve the insulation performance between the emission window and the device housing.

[0043] A sealing gasket 360 with a second window 361 is disposed on the top of the isolating member 350. The isolating member 350 is sealed against the inner wall of the device housing 110 through the sealing gasket 360, providing insulation and sealing. Specifically, the device housing 110, the sealing gasket 360, and the isolating member 350 are connected and fixed in sequence from the outside using bolts.

[0044] A third window 111 is provided through the device housing, and the second window 361 and the third window 111 correspond to the positions of the ray emission window, thereby forming a ray-shielding, electrically insulated, and oil-sealed X-ray generation window.

[0045] The X-ray shielding barrel 310 is fixedly installed inside the device housing through the first end cover 320 and the second end cover 330 to achieve the overall installation of the X-ray emitter.

[0046] As described above, the present invention provides an X-ray emitter 300 that features a newly designed spacer 350 made of lead tetroxide, combined with a rubber gasket 360 to create an X-ray emission window. This meets radiation shielding requirements while also providing an oil seal, excellent insulation, and a convenient installation solution. Furthermore, the end caps on both sides of the X-ray shielding barrel 310 utilize a mounting structure made of lead tetroxide, facilitating assembly of the X-ray tube 380 while also providing insulation.

[0047] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
