Problems solved by technology

[0004] At present, in general semiconductor microwave ovens, the microwave output of the semiconductor microwave generator is directly introduced into the waveguide box. The waveguide box can only be paired with a semiconductor microwave generator

Moreover, the current general semiconductor microwave oven generally uses a semiconductor microwave generator, and is equipped with a waveguide box to realize microwave introduction into the cavity. The microwave power is low, and the adjustable range of heating is small. If two or more semiconductor microwave generators are used It is not conducive to the miniaturization and structural simplification of the product due to the complex structure and large size of the waveguide box respectively, and it is difficult to realize because there are too many components and the limitation of the structural arrangement; two or more When the semiconductor microwave generators share a waveguide box, there are restrictions on the installation position and structure. The microwaves emitted by two or more semiconductor microwave generators will affect each other and cause danger. Therefore, based on the existing technology, Still can't find a better solution
