[0102] Figure 7 yes Figure 1 Schematic diagram of the structure of the detection module 600. Figure 1 , Figure 3 and Figure 7 In particular, the processing device 100 may further include a detection module 600 .

[0103] The detection module 600 may be disposed outside the shielding feature to determine whether electromagnetic wave leakage occurs in the processing device 100. In the present invention, "electromagnetic wave leakage occurs" means that the electromagnetic wave leakage exceeds a safety threshold.

[0112] The controller 450 can also be configured to control the electromagnetic wave generating system to reduce the power of the electromagnetic wave it generates or stop working to reduce or stop electromagnetic wave leakage when the value of the reference signal is greater than the second threshold during the continued processing stage (heating the object to be processed 500 after impedance matching).

[0113] In the absence of electromagnetic wave leakage, the power of the electromagnetic waves generated by the electromagnetic wave generating system may be greater in the continued processing stage than in the initial matching stage, so as to improve the processing efficiency of the object 500 to be processed.

[0114] The second threshold value may be greater than the first threshold value. The first threshold value may correspond to an electromagnetic wave radiation density of 5W / m 2 The second threshold value may correspond to an electromagnetic wave radiation density of 40W / m 2 .

[0115] In some further embodiments, the controller 450 may be configured to control the electromagnetic wave generating system to reduce the power of the electromagnetic wave it generates (for example, by 50%) when the value of the reference signal is greater than the second threshold for the first time during the continued processing stage; and to control the electromagnetic wave generating system to stop working when the value of the reference signal is still greater than the second threshold after the power is reduced, so as to improve safety and user experience.

[0116] In some embodiments, the detection circuit 610 may further include a detection circuit 612 and a rectification and filtering circuit 613 .

[0117] The detection circuit 612 may be configured to collect electrical signals related to electromagnetic wave leakage of the processing device 100;

[0118] The rectifier and filter circuit 613 may be configured to convert the electrical signal collected by the detection circuit 612 into a DC signal and to supply power to the light emitting element 611 .

[0119] In some embodiments, the detection circuit 612 may include a receiving antenna disposed outside the shielding features of the door body 300 and the cylinder body 210 to receive leaked electromagnetic waves.

[0120] In other embodiments, the detection circuit 610 may be configured to be electrically connected to the shielding feature of the door body 300 or the shielding feature of the cylinder body 210 at the first connection point and the second connection point, that is, the detection circuit 612 is an electrical connection line. The first connection point and the second connection point are spaced at different distances from the grounding point of the shielding feature, so as to determine whether the processing device 100 has electromagnetic wave leakage through the change in the induced voltage generated by the shielding feature under the action of the leakage electromagnetic wave.

[0121] In some further embodiments, the shielding feature of the barrel 210 may be configured to be grounded to ensure the reliability of the electrical connection.

[0122] The detection circuit 610 may be configured to be electrically connected to the shielding feature of the door body 300 to improve the sensitivity of electromagnetic wave leakage detection.

[0123] In some further embodiments, the detection circuit 610 may be configured to be electrically connected to the edge of the shielding plate 330 to improve the sensitivity of electromagnetic wave leakage detection.
