Combined machine head and ray imaging device

A combined machine head, comprising:

• a housing, having an enclosed cavity;
• an X-ray tube, arranged in the enclosed cavity;
• and
• a pump and a pipe, arranged in the enclosed cavity;
• wherein the pump is arranged on one side away from an anode of the X-ray tube, the pipe has a first end connected with an outlet of the pump and a second end extending to be near the anode of the X-ray tube;
• or the pump is arranged near the anode of the X-ray tube, the pipe has a first end connected to an inlet of the pump and a second end extending to one side away from the anode of the X-ray tube;
• wherein the housing comprises a cover plate and a housing body, and the combined machine head further comprises a first insulating barrier arranged in the enclosed cavity and dividing the enclosed cavity into a first cavity and a second cavity which are communicated, the cover plate is located on a side wall of the first cavity, the X-ray tube is arranged in the first cavity;
• and the pump is arranged on one side of the second cavity away from the anode of the X-ray tube;
• and
• wherein the combined machine head further comprises a second insulating barrier, arranged in the second cavity to be intersected with the first insulating barrier, and dividing the second cavity into a first sub-cavity and a second sub-cavity, the pump is arranged in the first sub-cavity, and the first sub-cavity is further used to arrange:
• a high frequency transformer of the combined machine head, with both terminals on a high-voltage side thereof respectively connected with the anode and a cathode of the X-ray tube;
• and
• a filament transformer of the combined machine head, with both terminals on a high-voltage side thereof respectively connected with two terminals of a cathode filament of the X-ray tube;
• and
• the second sub-cavity is used to arrange a circuit board of the combined machine head.
