Single-source microwave heating device

A single-source microwave heating device configured to heat up an object to be heated;

• the single-source microwave heating device comprising:
• a first power-divider having an input port, an isolated port, and two output ports;
• two opposite sides of the first power-divider being respectively an input side and an output side;
• the input port and the isolated port being located on the input side;
• and the two output ports being located on the output side;
• a microwave emitting module configured to emit a microwave into the first power-divider via the input port;
• the first power-divider dividing the microwave from the microwave emitting module between the two output ports according to a main divide ratio, and emitting the divided microwaves from the two output ports;
• and
• a shifting wave channel;
• each of two opposite ends of the shifting wave channel connected to a respective one of the two output ports of the first power-divider;
• a first phase-shifting module and a standing-wave heating chamber serially disposed in and along the shifting wave channel;
• wherein
• the first phase-shifting module is configured to shift a phase of a microwave passing through the first phase-shifting module;
• the first phase-shifting module has a first phase-adjusting assembly and a first driving assembly;
• a phase-shift provided by the first phase-shifting module varies according to a position of the first phase-adjusting assembly;
• the first driving assembly controls the position of the first phase-adjusting assembly;
• and
• the standing-wave heating chamber is configured to accommodate the object to be heated;
• wherein the microwaves emitted from the two output ports of the first power-divider interfere to form a standing wave in the shifting wave channel;
• positions of crests of the standing wave in the shifting wave channel vary according to a position of the first phase-adjusting assembly;
• wherein the standing wave in the shifting wave channel is absorbed by the object to be heated in the standing-wave heating chamber to heat up the object.
