Magnetron anode assembly and magnetron provided with magnetron anode assembly

Abstract

The invention relates to the technical field of a magnetron, in particular to a magnetron anode assembly and a magnetron provided with the magnetron anode assembly. A magnetron anode blade assembly provided by the invention comprises an anode tube and a plurality of anode blades arranged in the anode tube, wherein at least one flow guide groove is formed in each anode blade; the at least one flow guide groove is used for guiding molten welding materials positioned on the upper surface of the anode blades to one end, welded with the inner wall of the anode tube, of the anode blades, so that during the welding of the anode blades and the anode tube, the welding materials are molten on the upper surfaces of the anode blades; then, the molten welding materials flow to the welding position of the anode blades and the inner wall of the anode tube under the capillary effect and the gravity effect through the flow guide groove; the problem of welding failure of the anode blades and the anode tube due to the gathering of the welding materials on the upper surface of the anode blades can be avoided, so that the work frequency of the magnetron is more stable; the welding quality of the anode blades and the anode tube is higher; the welding success rate is improved; 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)
