Description

Technical Field

[0001] This utility model relates to the field of radiation generating device design technology, and in particular to a radiation generating device and detection equipment. Background Technology

[0002] X-ray generating devices (such as X-ray generating devices) are core components of non-destructive testing, medical imaging and other testing equipment. The high-voltage power supply module of the X-ray generating device provides stable high voltage for its X-ray tube and is a key component.

[0003] In existing technologies, the high-voltage circuit components of high-voltage power supply modules are generally encapsulated with solid insulating materials such as epoxy resin, and are completely covered by a casting body through a casting process to ensure insulation performance and structural stability. However, this method results in a large amount of material used for the casting body, which accounts for more than 60% of the total weight of the microfocus X-ray source, making the overall X-ray generating device relatively heavy.

[0004] Excessive weight of the X-ray generator directly leads to increased inertia during movement, which can easily cause imaging jitter when moving, turning, or adjusting its attitude, affecting the stability of the X-ray beam. This results in blurred images, reduced resolution, and consequently, poor detection accuracy of the equipment. Utility Model Content

[0005] This utility model discloses a radiation generating device and a detection equipment to solve the problem of poor detection accuracy of detection equipment in related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is implemented as follows: In a first aspect, this application discloses a radiation generating device, which includes a high-voltage power supply module and a radiation tube. The high-voltage power supply module includes a high-voltage circuit assembly and a casting body. The high-voltage circuit assembly is disposed inside the casting body, and the radiation tube is disposed outside the casting body and electrically connected to the high-voltage circuit assembly. The casting body has a weight-reducing structure.

[0007] Secondly, this application also discloses a detection device, which includes the radiation generating device described in the first aspect.

[0008] The technical solution adopted in this utility model can achieve the following technical effects: The radiation generating device disclosed in this application reduces the weight of the casting body by creating a weight-reducing structure on the casting body, thereby reducing the inertia of the radiation generating device during movement while ensuring insulation of the high-voltage circuit components.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0013] Please refer to Figures 1 to 3 This utility model discloses a radiation generating device. The disclosed radiation generating device can be an X-ray generating device or a gamma-ray generating device, etc. This application does not specifically limit the type of radiation generating device.

[0014] The disclosed radiation generating device includes a high-voltage power supply module 100 and a radiation tube. The radiation tube is the main part that generates radiation (such as X-rays, gamma rays, etc.). When the cathode of the radiation tube is energized, it can generate electrons. The electrons are accelerated under the action of the high-voltage electric field formed by the cathode and anode of the radiation tube and collide with the anode target surface, thereby generating radiation through the breech-induced radiation mechanism.

[0015] The high-voltage power supply module 100 is a component used to provide high voltage to the cathode and anode of the X-ray tube so as to form a high-voltage electric field between the cathode and anode.

[0016] The high-voltage power supply module 100 includes a high-voltage circuit assembly 110 and a casting body 120. The high-voltage circuit assembly 110 may include components such as a voltage multiplier circuit board and filter capacitors, which are used to increase the externally input voltage to the high voltage required by the X-ray tube (the process of accelerating electrons in the X-ray tube usually requires the application of a high voltage of thousands to hundreds of thousands of volts between the cathode and anode).

[0017] The high-voltage circuit assembly 110 is located inside the casting body 120. When the high-voltage circuit assembly 110 is working, it usually needs to output a high voltage of several thousand to hundreds of thousands of volts. The casting body 120 is a component that insulates and protects the high-voltage circuit assembly 110 to prevent the high-voltage circuit assembly 110 from forming a conductive path with the outside world. It also serves as a support structure for the high-voltage circuit assembly 110.

[0018] The X-ray tube is located outside the casting body 120 and is electrically connected to the high-voltage circuit assembly 110, which supplies the high voltage required by the X-ray tube. The casting body 120 has a weight-reducing structure. The casting body 120 is made of epoxy resin or silicone, etc. The material of the casting body 120 is not limited in this embodiment, but the casting body 120 needs to have good insulation properties.

[0019] It should be noted that the weight-reducing structure can be a groove, hole, or cavity, etc., and the embodiments of this application do not impose specific limitations on the form of the weight-reducing structure. The weight-reducing structure needs to maintain a sufficient distance from the high-voltage circuit assembly 110, and the thickness of the casting 120 at any location between the high-voltage circuit assembly 110 and the outer surface of the casting 120 needs to meet the requirements of the insulation thickness.

[0020] The radiation generating device disclosed in this application discloses a weight-reducing structure on the casting body 120. This reduces the weight of the casting body 120 while ensuring insulation of the high-voltage circuit assembly 110. Consequently, the inertia of the radiation generating device during movement is reduced, thereby improving the stability of the radiation generating device during movement and thus enhancing the detection accuracy of the detection equipment.

[0021] Specifically, the weight reduction structure may include a first groove 121 formed on the surface of the casting body 120, and the first groove 121 may be distributed at intervals with the high-voltage circuit assembly 110. There may be multiple first grooves 121, which may be distributed on the same surface of the casting body 120 or on different surfaces of the casting body 120. The arrangement of the first grooves 121 only needs to satisfy the requirement that "the thickness of the casting body 120 at any position between the high-voltage circuit assembly 110 and the outer surface of the casting body 120 meets the insulation thickness requirement". This application does not limit the location and number of the first grooves 121.

[0022] The radiation generating apparatus disclosed in this application makes the weight reduction structure relatively simple by setting the weight reduction structure to include a first groove 121 formed on the surface of the casting body 120.

[0023] In another embodiment, the weight-reducing structure may include through holes penetrating the casting body 120, and the through holes may be spaced apart from the high-voltage circuit assembly 110. There may be multiple through holes, which may be distributed on the same surface of the casting body 120 or on different surfaces of the casting body 120. The through holes are only required to satisfy the requirement that "the thickness of the casting body 120 at any location between the high-voltage circuit assembly 110 and the outer surface of the casting body 120 meets the insulation thickness requirement". This application does not limit the location and number of through holes.

[0024] The radiation generating apparatus disclosed in this application can remove more of the casting body 120 by setting the weight reduction structure to include a through hole penetrating the casting body 120, thereby making the weight reduction of the casting body 120 more advantageous.

[0025] Of course, in other embodiments, the weight reduction structure may simultaneously include a first groove 121 formed on the surface of the casting body 120 and a through hole penetrating the casting body 120. The specific structure of the weight reduction structure in this application embodiment is not limited.

[0026] Optionally, the weight reduction structure may include a second groove 123 formed on the surface of the casting body 120, and the high-voltage power module 100 may also include a transformer 130, which may be disposed in the second groove 123 and electrically connected to the high-voltage circuit assembly 110.

[0027] Specifically, the externally input voltage is first boosted by the transformer 130 and then sent to the high-voltage circuit assembly 110 for a second boost, thereby raising the externally input voltage to the high voltage required by the X-ray tube.

[0028] The radiation generating device disclosed in this application provides a second groove 123, which reduces the weight of the casting body 120. By placing the transformer 130 in the second groove 123, the second groove 123 not only serves as a weight-reducing structure for the casting body 120 but also as an installation structure for the transformer 130, thus making the second groove 123 serve two purposes.

[0029] To improve the overall compactness of the radiation generating device, the transformer 130 may optionally be flush with the opening of the second groove 123, or the transformer 130 may be lower than the opening of the second groove 123, so that the transformer 130 does not protrude from the outer surface of the casting body 120, thereby contributing to the overall compactness of the radiation generating device.

[0030] In one optional embodiment, the weight-reducing structure may include a third groove 124 formed on the surface of the casting body 120. The second groove 123 and the third groove 124 may be located on the same side of the casting body 120 and may be connected. The high-voltage power module 100 may also include a terminal 140, which may be embedded in the bottom of the third groove 124. The first end of the terminal 140 may be electrically connected to the high-voltage circuit assembly 110 via a wire. The second end of the terminal 140 may be exposed outside the bottom of the third groove 124 and may be used to electrically connect to the transformer 130 via a wire.

[0031] The radiation generating device disclosed in this application reduces the weight of the casting body 120 by creating a third groove 124 on the surface of the casting body 120. By setting a terminal 140, the transformer 130 is electrically connected to the high-voltage circuit assembly 110 through the terminal 140, making it easier for the transformer 130 to be electrically connected to the high-voltage circuit assembly 110. The terminal 140 is embedded in the bottom of the third groove 124, making the setting of the terminal 140 more stable.

[0032] Furthermore, the high-voltage power module 100 may also include an encapsulation structure 150 filled in the gap between the inner wall of the second groove 123 and the transformer 130, and filled in the third groove 124. The encapsulation structure 150 may be epoxy resin or silicone, etc. The embodiments of this application do not impose specific limitations on the material of the encapsulation structure 150, and the encapsulation structure 150 has good insulation performance.

[0033] The radiation generating device disclosed in this application fills the gap between the inner wall of the second groove 123 and the transformer 130 and the third groove 124 with an encapsulation structure 150, thereby encapsulating the electrical connection structure between the transformer 130 and the high-voltage circuit assembly 110 within the encapsulation structure 150. This provides insulation protection for the electrical connection structure between the transformer 130 and the high-voltage circuit assembly 110. Furthermore, the portion of the encapsulation structure 150 filling the gap between the inner wall of the second groove 123 and the transformer 130 can fix the transformer 130, thereby improving the stability of the transformer 130 installation.

[0034] There can be two terminals 140, spaced apart to meet insulation requirements. Each terminal 140 can be electrically connected to the positive and negative terminals of the transformer 130, respectively. Since the wires connecting the transformer 130 to the high-voltage circuit assembly 110 are connected to the terminals 140, and the terminals 140 are embedded in the casting body 120 with fixed positions, the positions of the wires connecting the transformer 130 to the terminals 140 are also relatively fixed. This prevents significant displacement of the wires connecting the positive and negative terminals of the transformer 130, thus failing to meet insulation requirements, when filling the encapsulation structure 150 into the third groove 124.

[0035] Optionally, the second end of the terminal block 140 may be flush with the bottom of the third groove 124, and the second end of the terminal block 140 may be provided with a plug hole 141. The transformer 130 may include an electrical connection terminal, which may be plugged into the plug hole 141.

[0036] The radiation generating device disclosed in this application provides a plug hole 141 at the second end of the terminal block 140, which allows the transformer 130 to be electrically connected to the terminal block 140 by plugging the electrical connection terminal into the plug hole 141, thereby simplifying the wiring method between the transformer 130 and the terminal block 140.

[0037] Because the high-voltage power module 100 generates high-frequency, high-voltage electromagnetic fields during operation, leakage of this electromagnetic interference can affect the control circuit of the X-ray tube, the signal acquisition module of the imaging system, etc., leading to blurred images and reduced resolution. To reduce the radiation from the high-voltage power module 100 to the outside world, optionally, the outer surface of the casting 120 can be covered with a metal shielding structure, which needs to be grounded. It should be noted that the shielding principle of the metal shielding structure is prior art and will not be elaborated upon in this embodiment.

[0038] The radiation generating device disclosed in this application reduces the radiation of the high-voltage power module 100 to the outside by covering the outer surface of the casting body 120 with a metal shielding structure, thereby alleviating the problems of image blurring and resolution reduction caused by the external radiation of the high-voltage power module 100.

[0039] Specifically, the metal shielding structure can be copper foil or aluminum foil, etc., attached to the outer surface of the casting body 120. In another embodiment, the metal shielding structure can be a metal coating sprayed onto the outer surface of the casting body 120.

[0040] The radiation generating device disclosed in this application sets the metal shielding structure as a metal layer sprayed on the outer surface of the casting body 120. Since the sprayed metal layer (such as copper or aluminum) is very thin, usually only tens to hundreds of micrometers thick, it hardly increases the overall weight of the radiation generating device, thereby helping to reduce the weight of the radiation generating device. Moreover, the metal coating can form a seamless and continuous conductive layer, thereby making the shielding performance of the metal shielding structure better.

[0041] This application also discloses a detection device, which includes the radiation generating device disclosed in the above embodiments.

[0042] The detection equipment disclosed in this application can reduce the weight of the casting body 120 by setting the radiation generating device disclosed in the above embodiments, thereby reducing the inertia of the radiation generating device during movement, thus improving the stability of the radiation generating device during movement, and thus helping to improve the detection accuracy of the detection equipment.

[0043] The above embodiments of this utility model mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be described in detail here.

However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of the present invention.
