Problems solved by technology
However, due to the characteristics that electromagnetic waves can quickly heat objects, the metal parts of contact thermometers or metal-wrapped temperature sensors directly placed in high-power microwave heating devices are irradiated by strong electromagnetic waves to generate high-frequency currents, generate electric sparks, and cause heat generation. In mild cases, the thermometer will fail, and in serious cases, the thermometer will be scrapped or burned

The invention provides a contact type temperature measurement device based on a microwave heating device and a using method of the contact type temperature measurement device. The contact type temperature measurement device is provided with the microwave heating device with a microwave resonant cavity and a probe temperature gauge, wherein an aluminum tube with a smooth surface sleeves a probe ofthe probe temperature gauge, and the probe sleeved with the aluminum tube penetrates through a through hole in the top of the micro heating device; a silicone tube sleeves the contact section of the aluminum tube and the through hole, a cup container is placed in the microwave resonant cavity, the cup container is provided with a container cover, and a cover hole used for the aluminum tube to penetrate through is formed in the container cover. By means of the contact type temperature measurement device based on the microwave heating device and the using method of the contact type temperature measurement device, the temperature in heated matter can be accurately measured, and the interference of electromagnetic waves with a temperature measurement element in the high-power microwave heatingdevice is overcome.
Description
Technical field [0001] The present invention relates to the technical field of temperature measuring devices, and in particular to a contact temperature measuring device based on a microwave heating device and its use. Background technique [0002] Since the first magnetron was produced in the 1930s, people have gradually used magnetrons in military, industrial production and household activities. Under the control of the mutually perpendicular constant magnetic field and constant electric field, the electrons in the magnetron interact with the high-frequency electromagnetic field and convert the energy obtained from the constant electric field into microwave energy. The microwave energy can quickly heat objects. [0003] Many attempts have been made to detect and control the temperature of heated substances in high-power microwave heating devices. The temperature detection of existing magnetron-type microwave heating devices usually uses non-contact infrared temperature mea...
