Claims

1. A microwave oven, comprising:

a furnace body having a heating chamber for receiving food;

a magnetron structure for generating microwaves in a second time sequence, wherein the second time sequence is positioned after the first time sequence; wherein, the microwave heats the water molecules in the mist and the water molecules in the food in the heating cavity;

and the second throttle valve structure is used for discharging mist in the heating cavity in a third time sequence, the third time sequence is positioned after the second time sequence, and the second throttle valve structure is closed in the first time sequence and the second time sequence.

2. The microwave oven of claim 1, further comprising a first throttle valve structure having a first operating state and a second operating state, wherein the atomizing structure is in communication with the heating chamber when the first throttle valve structure is in the first operating state; when the first throttle valve structure is in the second working state, the heating cavity and the atomizing structure are relatively independent.

3. The microwave oven of claim 2, wherein the first throttle valve structure is switched to the first operating state during the first time sequence; and in the second time sequence, the first throttle valve structure is switched to the second working state.

4. The microwave oven of claim 2, wherein the first throttle valve structure comprises a first housing and a first valve assembly, the first housing having a first air inlet for communicating with the atomizing structure and a first air outlet for communicating the first air inlet with the heating cavity; the first valve assembly is used for opening and closing the first air inlet or the first air outlet.

5. The microwave oven of claim 4, wherein the first valve assembly comprises a first door panel having the first operating state and the second operating state and a first driver for driving the first door panel to switch between the first operating state and the second operating state; wherein,,

6. The microwave oven of claim 5, wherein the first door panel is rotatably coupled to the first housing; or, the first door plate can be connected to the first shell in a turnover way; or, the first door panel is movably connected to the first housing.

7. The microwave oven of any one of claims 4-6 wherein the oven body further has a first through hole and a second through hole each in communication with the heating cavity, wherein the first through hole is for communication with the first air outlet and the second through hole is for venting the heating cavity;

8. The microwave oven of any one of claims 4-6, wherein the atomizing structure comprises a water storage tank having a water storage chamber and water inlet and outlet holes each communicating with the water storage chamber, the outlet hole being for communicating with the first air inlet, and an atomizer for atomizing water in the water storage chamber.

9. The microwave oven as claimed in claim 8, wherein a connection ring is formed to protrude from an outer wall of the water storage tank adjacent to the air outlet hole, and the connection ring extends into the first air inlet.

10. The microwave oven according to claim 9, wherein the atomizing structure further comprises two fixing members separately provided at both ends of the water tank, the fixing members including a first fixing portion connected to the water tank and a second fixing portion formed by bending and extending from the first fixing portion in a direction away from the water tank, the second fixing portion being adapted to be connected to the oven body.
