A magnetron anode assembly and a magnetron provided with the magnetron anode assembly

Abstract

The invention relates to the technical field of magnetrons, in particular to a magnetron anode assembly and a magnetron provided with the magnetron anode assembly. The magnetron anode vane assembly provided by the present invention includes an anode cylinder and a plurality of anode vanes arranged in the anode cylinder, each anode vane is provided with at least one diversion groove, wherein at least one diversion groove is used to place the The melted solder on the upper surface of the vane is guided to the end where the anode vane is welded to the inner wall of the anode cylinder, so that when the anode vane and the anode cylinder are welded, the solder melts on the upper surface of the anode vane, and then passes through the capillary action and gravity of the melted solder Under the action of the guide groove, it flows to the welding place between the anode blade and the inner wall of the anode cylinder, avoiding the problem of welding failure between the anode blade and the anode cylinder caused by the accumulation of solder on the upper surface of the anode blade, and making the working frequency of the magnetron more stable. The welding quality of the anode vane and the anode cylinder is higher, the success rate of welding is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of magnetrons, in particular to a magnetron anode assembly and a magnetron provided with the magnetron anode assembly. Background technique [0002] Magnetron is a vacuum electron tube that generates microwaves. Because of its high oscillation efficiency and high microwave output power, it is widely used as a microwave source for microwave applications such as household microwave ovens and industrial microwave heating equipment. Such as figure 1 As shown, the existing magnetron includes a shell 3, a tube core (not labeled in the figure) located in the shell 3, an input power supply 4 located at the bottom of the shell 3, and an input power supply 4 located between the inner wall of the shell 3 and the outer wall of the tube core. Between the cooling parts 5, where such as figure 2 As shown, the tube core includes an anode part, a cathode part 2, an output part 6 and a magnetic pole part forming a magnetic...

AI Technical Summary

Problems solved by technology

However, during the installation of the solder 14, the welding ring is easily deformed, causing its diameter to be less than the inner diameter of the anode cylinder 11 (such as Image 6 As shown), that is, the solder 14 cannot be close to the inner wall of the anode cylinder 11. When the solder 14 melts, the solder 14 is directly melted on the upper end of the anode vane 12 (such as Figure 7 As shown), it is difficult to flow into the connection between the anode blade 12 and the anode cylinder 11, so that the welding of the anode blade 12 and the anode cylinder 11 fails, and the operating frequency of the magnetron deviates from the design value

What is more serious is that when the solder 14 accumulates at the upper end of the anode vane 12, it may flow to the suspension between the anode vane 12 and the cross-connecting ring, so that the place where the anode vane 12 and the cross-connecting ring should be disconnected is short-circuited, causing the workpiece to be scrapped (such as Figure 8 shown)
