The invention belongs to the field of vacuum electronic devices, and particularly provides a miniaturized magnetron structure. According to the present invention, a neodymium iron boron or samarium cobalt permanent magnet material placed on an external support of a magnetron is adopted to replace an original ferrite magnetic ring so as to ensure the magnetic field intensity in an interaction space. The ferrite magnetic ring is not needed in the magnetron structure, and a neodymium iron boron or samarium cobalt permanent magnet is placed on the external support of the magnetron, so that the height and the width of the magnetron can be greatly reduced, and the magnetron structure is cuboid-shaped and can be matched with the shapes and the structures of the cooling fins and a filtering assembly synchronously, especially the filtering assembly. According to the invention, the output of an original same-direction choking coil from one end is improved into the output of a heterodromous choking coil from the left end and the right end, so that the miniaturized magnetron structure can stably work while being matched with a magnetic circuit structure. In conclusion, the invention provides the novel magnetron structure, and the miniaturization design of the magnetron structure is further realized.
Description
technical field [0001] The invention belongs to the field of vacuum electronic devices, and is mainly aimed at household microwave oven magnetrons, and proposes a new magnetron structure, a magnetic circuit system and a filter box structure, which effectively reduces the height and width of the magnetron, and further realizes the magnetron Control miniaturization. Background technique [0002] A microwave oven is mainly composed of a power supply, a magnetron, a control circuit, and a heating chamber. The power supply supplies high voltage to the magnetron, and the magnetron generates microwaves under the excitation of the power supply, and then transmits the microwaves to the heating chamber through a waveguide and an antenna. heating. The miniaturization of magnetrons has always been the main research direction of universities, enterprises, and research institutes, which not only improves the utilization rate, but also saves manufacturing costs. [0003] The magnetron is...
