Description

Technical Field

[0001] The present application relates to the technical field of X-ray tubes, and in particular to a window body and an X-ray tube capable of transmitting X-rays. Background Art

[0002] With the continuous development of the current medical device field, X-ray tubes have become one of the important means of medical diagnosis.

[0003] An X-ray tube primarily consists of a cathode assembly, an anode assembly, and a housing. The housing primarily supports the cathode and anode assemblies and ensures electron acceleration in a vacuum electric field. It's important to note that the interior of the housing requires a complete vacuum, and a window is located at the X-ray exit.

[0004] Therefore, the window body, as part of the housing, not only serves as the X-ray outlet but also supports the cathode and anode assemblies. Since the tube core rotates at high speed during normal operation, a large amount of heat is transferred to the window body. Since existing window bodies are relatively thin and lack other supporting structures, after a period of use, the window body will develop varying degrees of wrinkling and deformation due to the torque and heat from the rotation. This can cause the coaxiality of the cathode and anode assemblies inside the housing to change, shortening the life of the tube core.

[0005] With regard to the technical problem in the prior art mentioned above, how to solve the problem that the thickness of the window body of the existing X-ray tube is too thin and there is no other supporting structure, so that when the tube core rotates at high speed or a large amount of heat is transferred to the window body, the window body is prone to wrinkling and deformation to varying degrees, thereby shortening the life of the tube core, no effective solution has been proposed so far. Utility Model Content

[0006] The utility model provides a window body capable of transmitting X-rays and an X-ray tube, so as to at least solve the technical problem existing in the prior art of how to solve the problem that the window body of the existing X-ray tube is too thin and has no other supporting structure, so that when the tube core rotates at high speed or a large amount of heat is transferred to the position of the window body, the window body is prone to wrinkling and deformation to varying degrees, thereby shortening the life of the tube core.

[0007] According to one aspect of the present application, a window body capable of transmitting X-rays is provided, comprising: a window body and a plurality of support members, wherein the window body is an annular structure, and the plurality of support members are fixed in sequence to the inner side of the window body at preset intervals, and the support members are capable of transmitting the X-rays.

[0008] Optionally, the support member is made of beryllium.

[0009] Optionally, the support member includes, from top to bottom, a first support portion, a second support portion, and a third support portion toward the inner side of the window body; the inner side of the window body includes, from top to bottom, a first main body portion, a second main body portion, and a third main body portion; the first support portion corresponds to the first main body portion, the second support portion corresponds to the second main body portion, and the third support portion corresponds to the third main body portion.

[0010] Optionally, the thickness of the first support portion is smaller than the thickness of the third support portion, and the first support portion and the third support portion are provided with vertical surfaces toward the inner side of the window body; and the second support portion is used to connect the first support portion and the third support portion, and the second support portion is provided with an inclined surface toward the inner side of the window body.

[0011] Optionally, the window body includes an outwardly protruding fixing platform, and the bottom end of the third supporting portion is fixed on the fixing platform.

[0012] Optionally, the window body is made of steel.

[0013] According to another aspect of the present application, an X-ray tube is provided, comprising: a shell, and a cathode assembly and an anode assembly respectively arranged at both ends of the shell, including a window body capable of transmitting X-rays, and the window body is fixedly connected between the shell and the anode assembly.

[0014] The present application provides a window body capable of transmitting X-rays. The window body comprises a window body and a plurality of supporting members. The window body is annular in structure, and the plurality of supporting members are sequentially fixed to the inner side of the window body at predetermined intervals. The supporting members are capable of transmitting X-rays.

[0015] Because the multiple support members provided in this application all have a certain thickness, when the multiple support members are fixed to the inner side of the window body, the thickness of the window body is increased. This prevents the window body from wrinkling or deformation even when the tube core rotates at high speed or a large amount of heat is transferred to the window body. Moreover, because the multiple support members can transmit X-rays, the normal operation of the window body can be guaranteed.

[0016] As can be seen from the foregoing, the window body provided by the present application can, while ensuring normal operation, avoid wrinkling or deformation caused by high-speed rotation of the tube core or large amounts of heat, thereby extending the life of the tube core. This solves the technical problem in the prior art of how to solve the problem ...

[0025] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form.

[0026] Figure 1 is a schematic diagram of a window body 10 according to an embodiment of the present application; Figure 2 Schematic diagram of the support member 120 according to an embodiment of the present application. Figure 3 Schematic diagram of an X-ray tube according to an embodiment of the present application. Figure 1 、 Figure 2 and Figure 3 As shown, a window body 10 capable of transmitting X-rays includes: a window body 110 and a plurality of support members 120, wherein the window body 110 is a ring structure, and the plurality of support members 120 are fixed in sequence on the inner side of the window body 110 at preset intervals, and the support members 120 can transmit X-rays.

[0027] As described in the background, the window body, as part of the housing, not only serves as the X-ray outlet but also supports the cathode and anode assemblies. Because the tube core rotates at high speed during normal operation, significant heat is transferred to the window body. Existing window bodies are mostly 0.2 mm thick. Consequently, after a period of use, the window body will wrinkle and deform to varying degrees due to the torque and heat from rotation. This can cause the coaxiality of the cathode and anode assemblies inside the housing to change, shortening the life of the tube core.

[0028] In addition, the existing window body is generally thick at both ends and thin in the middle, which increases the difficulty of processing. And because the manufacturing process is demanding, the scrap rate of the window body is significantly increased, which will increase economic costs.

[0029] In view of this, the present application provides a window body 10 capable of transmitting X-rays. The window body 10 includes a window body 110 and a plurality of support members 120. The window body 110 is an annular structure, and a plurality of support members 120 are sequentially arranged inside the window body 110 at predetermined intervals.

[0030] Since the multiple support members 120 provided in this application all have a certain thickness, when the multiple support members 120 are fixed to the inner side of the window body 110, it is equivalent to increasing the thickness of the window body 110, so that even if the tube core rotates at high speed or a large amount of heat is transferred to the position of the window body 110, the window body 110 can be prevented from wrinkling or deformation.

[0031] Furthermore, the support member 120 provided in this application is also capable of transmitting X-rays. Therefore, since the multiple support members 120 are all capable of transmitting X-rays, adding a support member 120 of a certain thickness to the inner side of the window body 110 will not have any impact on the degree of X-ray transmission, thereby ensuring the normal operation of the window body 10.

[0032] As can be seen from the above, the window body 10 provided by the present application can prevent wrinkling or deformation caused by high-speed rotation of the tube core or large amounts of heat while ensuring normal operation, thereby extending the life of the tube core. This solves the technical problem in the prior art of how to solve the problem ...

[0033] Optionally, the support member 120 is made of beryllium.

[0034] Specifically, refer to Figure 1 and Figure 2 As shown, the material for making the support member provided in the present application can be, for example, beryllium. Among them, when the material for making the support member 120 is beryllium, P91 and beryllium materials can be used to make the support member 120. And because beryllium is almost transparent to X-rays, adding beryllium material to make the support member 120 will not have any effect on the transmittance of X-rays. And because the thermal expansion coefficient of beryllium material is similar to that of P91 material, it has a similar thermal expansion coefficient when heated. Therefore, the material for making the support member 120 has little effect on the deformation of the window body 110, and there will be no cracks due to thermal deformation.

[0035] Therefore, by using the support member 120 made of beryllium, it is possible to avoid cracks in the window body 110 due to thermal deformation while ensuring the normal operation of the window body 10.

[0036] Preferably, the support member 120 may also be made of ceramic.

[0037] Optionally, the support member 120 includes, from top to bottom, a first support portion 121, a second support portion 122 and a third support portion 123 toward the inner side of the window body 110; the inner side of the window body 110 includes, from top to bottom, a first main body portion 111, a second main body portion 112 and a third main body portion 113; the first support portion 121 corresponds to the first main body portion 111, the second support portion 122 corresponds to the second main body portion 112 and the third support portion 123 corresponds to the third main body portion 113.

[0038] Specifically, refer to Figure 1 and Figure 2 As shown, the support member 120 includes, from top to bottom, a first support portion 121, a second support portion 122, and a third support portion 123 toward the inner side of the window body 110. The inner side of the window body 110 includes, from top to bottom, a first body portion 111, a second body portion 112, and a third body portion 113.

[0039] Among them, the first support part 121 corresponds to the first main body part 111, so that the first support part 121 can support the first main body part 111 and increase the thickness at the position corresponding to the first main body part 111, thereby ensuring that the first main body part 111 of the window body 110 will not produce wrinkles or deformation due to the tube core rotating too fast or a large amount of heat.

[0040] Similar to the above, the second support portion 122 corresponds to the second main body portion 112, so that the second support portion 112 can support the second main body portion 112 and increase the thickness at the position corresponding to the second main body portion 112, thereby ensuring that the second main body portion 112 of the window body 110 will not be wrinkled or deformed due to the tube core rotating too fast or a large amount of heat.

[0041] Similar to the above, the third support portion 123 corresponds to the third main body portion 113, so that the third support portion 113 can support the third main body portion 113 and increase the thickness at the position corresponding to the third main body portion 113, thereby ensuring that the third main body portion 113 of the window body 110 will not produce wrinkles or deformation due to the tube core rotating too fast or a large amount of heat.

[0042] Optionally, the thickness of the first support portion 121 is smaller than the thickness of the third support portion 123, and the first support portion 121 and the third support portion 123 are provided with a vertical surface toward the inner side of the window body 110; and the second support portion 122 is used to connect the first support portion 121 and the third support portion 123, and the second support portion 122 is provided with an inclined surface toward the inner side of the window body 110.

[0043] Specifically, refer to Figure 1 and Figure 2As shown, since the thickness of the window body 110 at the position corresponding to the first body portion 111 provided in the present application is greater than the thickness of the window body 110 at the position corresponding to the third body portion 113, the thickness of the first support portion 121 of the support member 120 is less than the thickness of the third support portion 123. Furthermore, since the surfaces of the first body portion 111 and the third body portion 113 provided in the present application are arranged vertically, the first support portion 121 and the third support portion 123 of the support member 120 are also provided with vertical surfaces facing the inner side of the window body 110.

[0044] Therefore, the shapes and thicknesses of the first supporting portion 121 and the third supporting portion 123 of the supporting member 120 are consistent with those of the corresponding first body portion 111 and the third body portion 113 , thereby being able to better play a supporting role.

[0045] Similar to the above, since the window body 110 provided in this application is tilted at a position corresponding to the second body portion 112, the second support portion 122 of the support member 120 is also provided with an inclined surface facing the inner side of the window body 110. Thus, the shape and thickness of the second support portion 122 of the support member 120 match those of the corresponding second body portion 112, thereby better providing support.

[0046] Optionally, the window body 110 includes an outwardly protruding fixing platform 114 , and the bottom end of the third support portion 123 is fixed on the fixing platform 114 .

[0047] Specifically, refer to Figure 1 and Figure 2 As shown, the window body 110 further includes an outwardly protruding fixing platform 114 , so that the bottom end of the third support portion 123 can be fixed on the fixing platform 114 , thereby better fixing the support member 120 and preventing the support member 120 from falling off.

[0048] According to another aspect of the present application, an X-ray tube is provided, comprising: a shell 20, and a cathode assembly 30 and an anode assembly 40 respectively arranged at both ends of the shell 20, including a window body 10 capable of transmitting X-rays, and the window body 10 is fixedly connected between the shell 20 and the anode assembly 40.
