[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 3 As shown, a backscatter ray source comprises a shell, wherein a voltage multiplier plate and an insulating glue are provided in the shell, and the voltage multiplier plate and the insulating glue are solid-state packaged inside the shell; a main power board and a tube core shell are fixedly connected to the shell, and a tungsten sheet, an insulating layer and a tube core are installed in the tube core shell from the outside to the inside, and the insulating layer is arranged between the tungsten sheet and the tube core; a tube core head cover plate is also installed on one side of the tube core, and the tube core head cover plate is connected to the tube core shell.

[0019] By adopting the above structure, the tube core shell is designed to protect the tube core and shield radiation; by arranging the tungsten sheet and the insulating layer on the tube core, it is beneficial to play the role of insulation and radiation shielding; and the voltage multiplier plate and the insulating glue are solidly encapsulated inside the shell, which increases the overall insulation performance. The device is small and light, and is easy to use and install.

[0020] Specifically, if Figures 1 to 3 As shown, the tube core housing is symmetrically provided with a number of fin-shaped grooves for increasing the heat dissipation area. The fin-shaped design plays a certain role in the heat dissipation of the tube core and the whole machine, which is conducive to reducing the internal heat of the product, achieving a more sufficient heat dissipation effect and extending the service life of the product.

[0021] like Figures 1 to 3As shown, the housing is also provided with three fixing holes for fixing. The fixing holes on the housing are used to fix the housing with screws, which is convenient for product use and has a stable and reliable structure.

[0022] like Figures 1 to 3 As shown, the surface of the shell is subjected to high gloss and nickel plating, and the surface of the tube core shell is also subjected to high gloss and nickel plating. The nickel plating is beneficial to increase its insulation performance, and the high gloss surface treatment is beneficial to make the device more beautiful.

[0023] like Figures 1 to 3 As shown, through the internal structure of the shell and simulation calculation, several insulating sheets can be installed inside the shell. By installing several insulating sheets inside the shell, especially at the places with larger electric fields, it is beneficial to achieve better insulation effect.

[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is that it includes three schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0026] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0027] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
