Description

technical field

The invention belongs to the field of environmental protection devices for body treatment, and in particular relates to a microwave body treatment device and a treatment method.

Background technique

Microwave heating is a heating method in which microwaves directly act on the inside of medium molecules. Under microwave radiation, the molecules inside the medium generate heat at the same time, and the temperature rises as a whole. Compared with the traditional indirect heating method based on heat conduction, the temperature rises faster. As the heating process proceeds, the water on the surface of the medium evaporates, and the medium presents a temperature gradient that is higher on the inside and lower on the outside, so that the water migrates from the inside to the outside, greatly improving the drying efficiency. At present, microwave technology has been applied to the cremation of remains.

Because the dielectric properties of different parts of the body change with the change of humidity. Where the humidity is low, the dielectric constant is relatively small, the medium’s ability to absorb and convert microwaves is reduced, and the temperature rise is slow; on the contrary, where the humidity is high, the dielectric constant is larger, and the medium’s ability to absorb and convert microwaves is stronger. Fast temperature rise. In the dead body, the dielectric constant of muscle is greater than that of fat, and the dielectric constant of fat is greater than that of bone. How to ensure that the cremation speed of different parts of the dead body is basically the same is a problem that needs attention.

The controller acquires the front image and the side image before the cremation of the dead body taken by the camera 40, and compares it with the reference scale in the image (such as the length of the dead body supporting plate), to obtain the height, thickness and width of the dead body.

S3. The controller uses machine learning to obtain the bones, visceral regions and limb regions of the remains. The specific method is as follows: the controller obtains CT detection images of remains of different body types as a sample data set; divides the sample data set into a training set and a test set; annotates the training set pictures and divides them into at least bones, visceral regions, and limbs Training set sub-pictures; input the training set sub-pictures into the machine learning model to train the machine learning model, so that the machine learning model learns the training set sub-pictures to identify targets (bones, visceral regions and limb regions); input the test set to the machine In the learning model, the machine learning model identifies the recognition target in the picture to be marked.

S4. The controller selects different parts and different numbers of microwave heaters 14 to work according to the height and width of the body.

In the present invention, the microwave heater 14 is mainly composed of a microwave magnetron (abbreviated as a magnetron), a waveguide, a circulator and a directional coupler.

Among them, the magnetron is the source of microwave generation. When it is energized, it is placed in a constant electric field and magnetic field perpendicular to each other. The electrons in the magnetron oscillate at high frequency under the control of the electromagnetic field and transfer energy to pass outward. A waveguide is a hollow guide with a very smooth inner wall. Using it to transmit electromagnetic waves can minimize the energy loss of electromagnetic waves. At present, circular or semicircular waveguides and rectangular waveguides are common. The circulator can separate electromagnetic wave signals of different frequencies, and the microwave can only circulate in one direction inside the circulator. Therefore, adding a matching load at the appropriate position of the three-port circulator can effectively avoid the damage caused by microwave reflection to the magnetron. The directional coupler is used to separate microwave incident and reflected signals. By connecting to a microwave power meter, the incident and reflected microwave power can be detected in real time. In the microwave heating cavity, the incident microwave interacts with the medium to complete energy conversion.

A microwave heater composed of a magnetron, a waveguide, a circulator and a directional coupler is a prior art, and its structure and principle will not be described in detail here.
