Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic waves, in particular to an electromagnetic wave stirring rod. Background Art
[0002] Electromagnetic waves are composed of electric and magnetic fields that oscillate in phase and are perpendicular to each other, moving in space in the form of waves. Their propagation direction is perpendicular to the plane formed by the electric and magnetic fields, effectively transferring energy and momentum. Science usually divides electromagnetic waves into seven basic types, but they are all different manifestations of the same phenomenon. In order of decreasing wavelength or increasing frequency, common names are: radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays and gamma rays. Among them, microwaves are widely used. For example, microwave ovens are essential household appliances, mainly used to heat food. Common microwave ovens usually have a stirrer to disturb the microwave energy inside the microwave oven to achieve uniform heating.

Since the stirrer itself has a limited length, the stirring range of the stirrer when rotating is limited and cannot cover the heating area inside the microwave oven. Once the area occupied by the heated food is large, the food outside the coverage range of the stirrer will not be heated enough, resulting in uneven heating of the food and affecting consumption.
