Abstract

The invention discloses a magnetron excitation cavity comprising a rectangular portion and a semi-cylindrical upper portion disposed above the rectangular portion, wherein the rectangular portion andthe upper portion are hollow and communicate with each other to form a cavity; the top of the rectangular portion matches and communicates with the rectangular surface of the upper portion; the bottomof the rectangular portion is equipped with an opening; a plurality of interference bars are disposed in the cavity; and a panel of the rectangular portion connected to one of semicircular surfaces is provided with a welding ring for mounting a magnetron. By designing the upper portion of the magnetron excitation cavity into a semi-cylindrical shape, the reflection transmission of microwaves is improved and the sparking phenomena of the boundary are reduced. By disposing the welding ring in the rectangular portion of the excitation cavity, the precise welding of the excitation cavity and themagnetron are ensured, thereby achieving a purpose of ensuring the product quality, facilitating the reflection and transmission of microwaves, achieving efficient coupling transmission of microwavesand improves transmission efficiency.
