[0002] X-ray source devices are special devices that can generate X-rays. Due to the penetrating, fluorescent, and photographic properties of X-rays, objects form images on the detection medium. Since each object has different density and thickness, the degree to which X-rays are absorbed varies when X-rays penetrate different objects. Therefore, the amount of X-rays reaching the detection medium varies, forming images with different black and white contrasts. X-rays are widely used in medical, industrial, and security inspection fields for inspection or flaw detection.

[0003] In the present technology, in order to achieve miniaturization, the X-ray tube and the control unit are generally integrated together to form a portable X-ray source device.

Detailed Implementation

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] Embodiments of this utility model: such as Figure 1-4 As shown, a highly sealed radiation source device is disclosed, including a housing 1, a radiation tube 2 disposed inside the housing 1, and a control unit 3 disposed outside the housing 1; the housing 1 is provided with a housing radiation outlet 10, the radiation tube 2 has a radiation outlet, the radiation outlet and the housing radiation outlet 10 are positioned opposite each other, and the housing radiation outlet 10 can be disposed on the side or bottom of the housing 1.

[0028] The aforementioned X-ray tube specifically refers to a device used to generate X-rays. It includes a negative electrode and a positive electrode. By applying a high voltage, electrons are accelerated from the negative electrode and collide with the positive electrode to generate X-rays. To generate a sufficiently high voltage to accelerate the electrons, the X-ray tube needs to be connected to a high-voltage generator. This high-voltage generator can generate and regulate the required high voltage and deliver it between the positive and negative electrodes of the X-ray tube. In this way, a sufficiently large electric field can be formed inside the X-ray tube to accelerate electrons and generate X-rays.

[0029] During operation, the electron beam emitted by the electron emitter of the negative electrode assembly is accelerated by the accelerating electric field within the X-ray tube, forming a focused electron beam. This focused electron beam bombards the positive electrode target, generating diffused X-rays, which are then emitted outwards through the X-ray outlet. Due to the relative positions of the X-ray outlet 10 and the X-ray exit, the diffused X-rays are ultimately emitted outwards through the X-ray outlet 10.

[0030] The control unit 3 is housed in the enclosure 1. The control unit includes a voltage drive module, a filament control module, a signal feedback module, and a battery module, all electrically connected to the high-voltage generator. The voltage drive module and the filament control module provide the voltage drive and filament current drive required for the X-ray tube's operation, respectively. The signal feedback module receives the high-voltage and positive current signals from the X-ray tube to monitor the stability of the high-voltage and positive current. The battery module serves as a backup battery.

[0031] The control unit 3 in the prior art has poor sealing, resulting in poor waterproofing and dustproofing, which affects the service life of the entire device.
