Magnetron Antenna Cover

Abstract

Disclosed is an antenna seal cap of a magnetron. The antenna seal cap is defined by a seal cap wall and arranged on the upper portion of an anode casing of the magnetron, an upper sealing chamber is formed in the seal cap wall, an antenna outlet is arranged on the upper portion of the antenna seal cap, the seal cap wall at the upper end of the antenna seal cap uniformly bends toward the periphery of the antenna seal cap to form an outer seal cap wall, the antenna outlet is formed at the junction position of the seal cap wall and the outer seal cap wall, and the outer seal cap wall extends outwards to form a ring-shaped gasket ring. The gasket ring shields a gap at the position of a through hole in the middle of an upper casing, and the shielding portion of the gasket ring is capable of effectively preventing microwaves from leaking during the working of the magnetron; and the gasket ring and the antenna seal cap are formed in an integrated mode so that no gaps are formed between the gasket ring and the antenna seal cap, the leakage of the microwaves between the gasket ring and the antenna seal cap is avoided, the magnetron is more reliable, and negative influences of high frequency harmonic waves on surrounding human bodies and electrical elements are reduced during the working of the magnetron.

Description

technical field [0001] The invention belongs to the technical field of magnetrons, and in particular relates to a gasket ring with an integrated structure, thereby preventing microwave leakage, simplifying the process flow, and reducing production costs for the antenna cover of the magnetron. Background technique [0002] figure 1 It is a longitudinal sectional view of a magnetron structure in the prior art; figure 2 is a structural schematic diagram of a magnetron antenna cover in the prior art; image 3 is a structural schematic diagram of a gasket ring in the prior art; Figure 4 is a cross-sectional view of a prior art gasket ring; Figure 5 is a cross-sectional view of a prior art magnetron antenna cover and gasket ring combination. [0003] Such as Figure 1 to Figure 5 As shown, the magnetron mainly includes: a positive electrode part; a negative electrode part; a magnetic pole part; and a microwave emitting part. The positive electrode part is composed of a ba...

AI Technical Summary

Problems solved by technology

[0013] However, the magnetron antenna cover and the gasket ring in the prior art must be closely matched, so the requirements for the processing technology are relatively high

If the dimensions of the antenna cover and the gasket ring are improperly matched, there will be a gap between the antenna cover and the gasket ring, and the microwaves in the magnetron will leak out of the above gap, causing damage to the human body and electrical components around the microwave oven. adversely affect

In addition, the antenna cover and the gasket ring are two parts, and there are many technological processes during production and processing, resulting in a decrease in production efficiency
