[0038] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification and in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0039] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0040] Current X-ray generators generally consist of the following parts:

[0041] 1. The main box provides an insulating and shielding protective shell for the entire system;

[0042] 2. Sealing cover, used to seal the main box, isolate the outside air, and ensure the normal operation of the X-ray tube and other devices in the main box;

[0043] 3. A booster unit is arranged in the main box, and the booster unit contains a ray tube and a circuit for providing a high voltage electric field to the ray tube and heating the filament;

[0044] 4. The control unit is located outside the main box and is used to connect the external main power supply circuit and control communications.

[0045] Existing products have the following disadvantages:

[0046] 1. Large size, taking up a lot of equipment space, making it difficult to miniaturize the whole equipment, resulting in high cost of the whole equipment;

[0047] 2. The control unit is larger than the main box and is separated, which is not convenient for carrying;

[0048] 3. Irregular shape, low space utilization, and inconvenient transportation;

[0049] 4. Currently, most radiation sources are insulated with insulating oil. This method has high requirements for the sealing of the outer shell, and the requirements for parts processing accuracy and assembly are also correspondingly increased, which leads to a significant increase in parts cost and assembly cost, while the production efficiency is low.

[0050] Therefore, the present application provides an X-ray generator and a detection device to solve the above technical problems.

[0051] See also Figure 1 and Figure 2An X-ray generator provided in an embodiment of the present application includes a housing 10, an X-ray tube 20, a booster unit 30, a control unit 40 and a heat dissipation unit 50. The X-ray tube 20, the booster unit 30 and the control unit 40 are all arranged in the housing 10. The booster unit 30 is electrically connected to the X-ray tube 20, and the control unit 40 is electrically connected to the X-ray tube 20 and the booster unit 30 respectively. At least part of the heat dissipation unit 50 is arranged outside the housing 10 for heat dissipation. The housing 10 has a glue filling port 101, the input end of the control unit 40 is exposed at the glue filling port 101, and the output end of the control unit 40 is electrically connected to the X-ray tube 20 and the booster unit 30 respectively, wherein the glue filling port 101 is configured to fill high-voltage insulating sealant into the housing 10, and the high-voltage insulating sealant covers the X-ray tube 20, the booster unit 30 and the control unit 40. A sealed structure is formed inside the housing 10 to prevent high voltage from discharging with air or a shielding shell.

[0052] In some embodiments, the high-voltage insulating sealant is a two-component silicone elastomer. Since the high-voltage insulating sealant is a two-component silicone elastomer, the X-ray generator has the advantages of good pressure resistance and heat dissipation effect.

[0053] Specifically, silicone elastomer is a two-component set material. It consists of two liquid components, A and B. When the two components are fully mixed in a 1:1 weight ratio or volume ratio, the mixed liquid will solidify into a flexible elastomer. It is a low-density, flame-retardant, highly insulating, and anti-vulcanization silicone material. Its low viscosity and high thermal conductivity are perfectly used in the potting and packaging of precision components, and safely meet various heat dissipation, temperature resistance, and insulation requirements; moreover, silicone elastomer is a high thermal conductivity silicone, which fully meets the thermal conductivity requirements and has good thermal conductivity; the insulation performance of silicone elastomer is also excellent, which can ensure the consistency of the electrical performance of the product before potting.

[0054] In some embodiments, the housing 10 is provided with an exit window 103 that cooperates with the X-ray tube 20. For example, the ground electrode in the X-ray tube 20 is clamped in the exit window 103 on the housing 10, and the high voltage electrode in the X-ray tube 20 is encapsulated in a high voltage insulating sealant.

[0055] In some embodiments, a filter is provided in the exit window 103. The exit window 103 cooperates with the X-ray tube 20 to emit X-rays, and the filter provided in the exit window 103 can reduce the long-wave X-rays with weak puncture force, as an inherent filter of the X-rays. The center of the filter is designed to be at the center of the X-ray emission.

[0056] During the glue pouring process, the glue barrel window tooling is arranged in the exit window 103 to ensure the sealing. After the colloid is solidified, the glue barrel window tooling is taken out, and silicone is applied on the exit window 103. The filter is placed in the exit window 103 and pressed around the filter.

[0057] In some embodiments, the shell 10 is square in shape as a whole, which improves space utilization and facilitates transportation and processing.

[0058] In some embodiments, the housing 10 is made of aluminum.

[0059] In some embodiments, the shell 10 is constructed in the form of a sealed cover. For example, the shell 10 includes a first end and a second end that are relatively arranged. The above-mentioned glue filling port 101 is arranged at the first end, and the second end is an opening 102. The heat dissipation unit 50 is sealed and connected to the opening 102 to accelerate heat dissipation.

[0060] For the convenience of description, the first end and the second end are defined as the left and right directions of the housing 10 respectively.

[0061] In some embodiments, the boost unit 30 is accommodated at the top of the housing 10, and the control unit 40 is accommodated at the bottom of the housing 10. Figure 3 As shown, the housing 10 includes a main body 110, a bottom plate 120 and a cover plate 130, the bottom plate 120 and the cover plate 130 are arranged vertically, and the bottom plate 120 and the cover plate 130 are both detachably connected to the main body 110. Specifically, the booster unit 30 is fixed to the main body 110, the control unit 40 is fixed to the bottom plate 120, and the bottom plate 120 is covered at the bottom of the main body 110. The X-ray tube 20 is fixed to the heat dissipation unit 50, and the heat dissipation unit 50 is fixed to the right part of the main body 110, and then the cover plate 130 is fixed to the front part of the main body 110, so as to realize the overall assembly of various components, so that various components are installed in the housing 10, the installation datum is unified, and the risk of installation difficulties or uncontrollable radiation leakage due to inconsistent installation standards of various components is reduced.

[0062] It should be noted that the above-mentioned detachable connection includes but is not limited to the cooperation between screws and holes.

[0063] In some embodiments, a notch 111 is disposed on the main body 110 , and the bottom plate 120 and the notch 111 together form the glue filling port 101 .

[0064] In some embodiments, the exit window 103 is formed on the cover plate 130 .

[0065] In some embodiments, the boost unit 30 includes a boost feedback board 310 and a high-voltage multiplier rectifier 320 electrically connected thereto, the high-voltage multiplier rectifier 320 is electrically connected to the X-ray tube 20 , and the control unit 40 is electrically connected to the boost feedback board 310 .

[0066] In some embodiments, the boost feedback plate 310 is fixed to the main body 110. For example, the main body 110 and the boost feedback plate 310 are both provided with threaded holes, and screws are passed through the threaded holes on the main body 110 and the boost feedback plate 310 in sequence and then tightened to fix the boost feedback plate 310 to the main body 110. The high-voltage multiplier rectifier 320 is welded to the boost feedback plate 310.

[0067] Among them, the boost feedback board 310 modulates the low-voltage DC power supply from the battery or other low-voltage DC power supply into an AC high-voltage power supply of hundreds to thousands of volts, and transmits the AC high-voltage power supply to the high-voltage multiplier rectifier 320. After further amplification and rectification by the high-voltage multiplier rectifier 320, it becomes a DC high-voltage power supply of more than 10,000 volts. The high-voltage DC power supply is connected to the high-voltage pole of the X-ray tube 20.

[0068] In some embodiments, the heat dissipation unit 50 includes a heat dissipation plate 510 , on which a plurality of heat dissipation fins 520 are spaced apart, wherein the X-ray tube 20 is fixed to one end of the heat dissipation plate 510 away from the heat dissipation fins 520 .

[0069] It should be noted that the X-ray tube 20 can be fixed to the heat sink 510 by a fastening device. For example, a first threaded hole is provided on the heat sink, the first threaded hole passes through the heat sink, and a second threaded hole is provided on the X-ray tube 20.

Specifically, a plurality of integrally formed protrusions are disposed on the bottom plate, and the mounting plate 60 abuts against the plurality of protrusions to form the gap. The setting of the gap can ensure that the colloid can penetrate during the glue pouring, thereby ensuring a low bubble rate of the colloid.

[0071] In some embodiments, to facilitate the connection between the X-ray tube 20 and the control unit 40, the X-ray generator also includes a cable connector 70, which is fixed in the shell 10. For example, the cable connector 70 is fixed to the main body 110, and the X-ray tube 20 is electrically connected to the control unit 40 through the cable connector 70.

[0072] It can be understood that the cable connector 70 and the booster unit 30 do not interfere with each other, that is, the cable connector 70 and the booster unit 30 are spaced apart in the housing 10. For example, the cable connector 70 is fixed to the left part of the main body 110, and the booster unit 30 is fixed to the rear part of the main body 110.
