| description | The utility model provides an X-ray generating device which comprises a cathode configured to generate emission electrons, an anode configured to receive electron bombardment and generate X-rays, a shell configured to accommodate the cathode and the anode and provide a vacuum environment, and a ray window configured to receive the emission electrons, the X-ray transmitting part is constructed to face the X-ray emitting position so as to transmit the X-rays; the platform structure is configured to protrude along the outer side of the shell relative to the X-ray emergent position so as to form an opening, and the ray window is installed at the end of the opening so as to seal the shell. The arrangement of the platform structure enlarges the distance between the focal position of the X-ray emitted by the X-ray generating device and the ray window, partially absorbs bombardment of the X-ray, secondary electrons and other scattered electrons, does not affect the emission of the X-ray, reduces the deformation proba |
