Abstract

The invention discloses a multistage step-up system for an X-ray machine. The multistage step-up system comprises a lithium battery pack, a liquid crystal display circuit, a master control unit, a high-frequency step-up circuit, an X-ray tube and a voltage-multiplying rectifying circuit. An inverter step-up circuit and a pulse width modulation circuit are further connected in series between the lithium battery pack and the high-frequency step-up circuit. The lithium battery pack and the inverter step-up circuit constitute a primary step-up circuit. The pulse width modulation circuit, the highfrequency step-up circuit, the voltage-multiplying rectifying circuit, and the X-ray tube constitute a secondary high-voltage step-up circuit. The liquid crystal display circuit and the master controlunit constitute a display/control circuit to display and control the exposure time. The master control unit, the pulse width modulation circuit, and the X-ray tube constitute a filament drive circuitthat controls the magnitude of the current of an exposure tube. The multistage step-up system is simple in structure, reasonable in design, safe and reliable, can increase the 24V voltage of the lithium battery pack to 70kV, and can be directly applied to a medical portable X-ray dental machine.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a multi-stage boosting system for X-ray machines, and is especially suitable for portable dental machines with low power output. Background technique [0002] With the upgrading of residents' consumption, my country's oral medical market is in a stage of rapid development. With the development of dental implants and orthodontics, doctors and patients have higher and higher requirements for dental imaging equipment, which are small in size, light in weight, less in radiation, and have more exposure times after a full charge. In response to the new market demand for products, a portable energy storage dental X-ray machine is developed. This dental X-ray machine works at high frequency, small in size, light in weight, and less in radiation. The number of exposures can be increased after a full charge. Reach 150 sheets. Since the power supply is powered by a small 24V lithium...
