Abstract: The accurate microwave heating method and device based on the time reversal calibration technology are provided. The heating method is applied in the heating device having a signal generator and multiple microwave transceivers, including steps of: placing a material to be heated into the heating device, wherein the signal generator is arranged at a placement position of the material to be heated; according to the placement position of the material to be heated in the heating device, controlling the signal generator to emit a beacon microwave signal; controlling the microwave transceivers to emit microwave power signals according to the received beacon microwave signal; during heating, when a preset trigger condition is detected to be triggered and a current temperature of the material to be heated does not meet a preset temperature, repeating emitting the first and microwave power signals until meeting the preset temperature, and then stopping working.

Abstract: An air purification device able to kill bacteria and viruses is provided, including an air channel, an air pump, a filtering device, and an electrodeless ultraviolet sterilization device. The electrodeless ultraviolet sterilization device is arranged inside the air channel and includes a microwave generator, an electrodeless ultraviolet tube, and a uniform radiator. The uniform radiator is a coaxial cable with gaps provided thereon. The electrodeless ultraviolet tube is a hollow columnar quartz tube. The coaxial cable is arranged in a hollow portion of the quartz tube. The coaxial cable is connected to the to microwave generator. The air purification device has a compact structure. Through arranging the electrodeless ultraviolet sterilization device inside the air channel, large-granular dust in the air is filtered, and meanwhile, bacteria and viruses in the air are effectively killed. Moreover, the present invention is safe and effective and has high sterilization efficiency and a low production cost.

Abstract: A microwave oven based on phased arrays includes a heating chamber; a microwave feed source, wherein the microwave feed source includes multiple array antennas which are evenly distributed at a top portion of the heating chamber; mass sensors which are adapted for at least dividing a bottom portion of the heating chamber into two parts; a phase control module for connecting the mass sensors and the array antennas, wherein the mass sensors are adapted for transmitting quality signals of an object to be heated to the phase control module. The quality signals of the object of the mass sensors are transmitted back to the phase control module, in which the microwave is radiated more to the food with high quality, that is, the space controllable heating is achieved, so as to improve energy efficiency and heating uniformity.
