[0021] Preferably, the microwave resonance probe comprises a metal shell 100, a resonance mechanism 200 and a spoke 300, wherein:

[0022] The resonance mechanism 200 comprises a cathode electron generating device 210, a solenoid 220, two permanent magnet rings 230 and a plurality of metal blocks 240, the cathode electron generating device 210 is externally arranged in the metal shell 100, the solenoid 220, the permanent magnet ring 230 and the metal block 240 are internally arranged in the metal shell 100, the metal blocks 240 are arranged at the outer periphery of the permanent magnet rings 230, the two permanent magnet rings 230 have a spacing therebetween to form an accommodating space 201, the solenoid 220 is located in the accommodating space 201, one side of the metal block 240 is inserted into one of the permanent magnet rings 230, and the other side of the metal block 240 is inserted into the other permanent magnet ring 230; so that the electrons generated by the cathode electron generating device 210 are deflected in the magnetic field generated by the solenoid 220.

[0023] The spoke 300 is partially internally arranged in the metal shell 100, one end of the spoke 300 extends out of the metal shell 100 (the length of the spoke 300 extending out of the metal shell 100 is only a small part of the spoke 300), and the other end of the spoke 300 abuts against the junction of the permanent magnet ring 230 and the metal block 240; so that the electrons interact with the metal shell 100 after flying out of the permanent magnet ring 230, resonate in the cavity inside the metal shell 100, and further generate microwaves.

[0024] The metal shell 100 is internally arranged with a cavity (not shown in the figure), and the accommodating space 201 is in communication with the cavity.

[0025] The metal blocks 240 between the two adjacent metal blocks 240 (together with the two permanent magnet rings 230) form a metal block opening 202, the metal block opening 202 is in communication with the accommodating space 201, and the metal block opening 202 is in communication with the cavity.

[0026] The metal shell 100 is provided with a main body part 110, a contraction part 120 and an opening part 130, the main body part 110, the contraction part 120 and the opening part 130 are sequentially connected and integrally formed, the solenoid 220, the permanent magnet ring 230 and the metal block 240 are located in the main body part 110, and the cavity is distributed in the main body part 110, the contraction part 120 and the opening part 130; so that the solenoid 220, the permanent magnet ring 230 and the metal block 240 are simultaneously collected in the main body part 110. Since the inner diameter of the contraction part 120 is significantly smaller than the inner diameter of the main body part 110, and the inner diameter of the opening part 130 gradually increases from the side close to the contraction part 120 to the side away from the contraction part 120, it is beneficial to guide the microwaves to be emitted from the cavity.

[0029] As an illustration, the two sides of the solenoid 220 are two permanent magnet rings 230, and the metal blocks 240 are arranged outside the permanent magnet rings 230, so that the electrons generated by the cathode electron generating device 210 are deflected in the magnetic field generated by the solenoid 220. The electrons are further deflected under the action of the permanent magnet rings 230 and the metal blocks 240. The deflected electrons spiral outward, interact with the metal cover 100 after flying out of the permanent magnet rings 230, resonate in the cavity inside the metal cover 100, and further generate microwaves. The microwaves are guided by the spokes 300 and propagate along the length direction of the solenoid 220, and are emitted from the opening 133 of the metal cover 100.

[0030] As an example, the microwaves generated by the microwave resonance probe of the embodiment can be used to detect internal defects of the detected object, for example, cold welding defects of polyethylene gas pipeline hot melt joints.

[0031] It is worth mentioning that the specific structure of the cathode electron generating device 210 and other technical features involved in the utility model patent application should be regarded as prior art, and the specific structure, working principle and possible control method and spatial arrangement method involved in the technical features can be selected by using the conventional selection in the field, and should not be regarded as the invention point of the utility model patent, and the utility model patent will not be further expanded and described in detail.
