[0027] The movable block 602 slides inside the guide groove 606, and the limit block 605 is slidably connected with the guide groove 606 and the fixed block 601 through the movable block 602;

[0028] Two extrusion springs 607 are provided, the two extrusion springs 607 are symmetrically distributed, and the two extrusion springs 607 are both in a stretched state;

[0029] Specifically, Figure 1 , Figure 3 and Figure 5 As shown, when in use, the movable block 602 is pushed to move horizontally by resetting the squeezing spring 607, thereby driving the limiting block 605 to pass through the through hole 603 and insert into the limiting groove 604, and then the activated carbon protection plate 10 is limited. Through the above operation, dust and small animals in the outside air are prevented from entering the inside of the housing 1, thereby reducing the influence of outside dust and small animals on the microwave power amplifier body 3, and improving the service life of the microwave power amplifier body 3;

[0033] A stirring mechanism 12 is provided inside the radiator 5;

[0034] The stirring mechanism 12 includes a protective frame 1201, and the protective frame 1201 is arranged inside the radiator 5, a stirring motor 1202 is installed inside the protective frame 1201, and a stirring shaft 1203 is installed on one side of the stirring motor 1202, and a driving bevel gear 1205 is sleeved on the outer side of the stirring shaft 1203, a driven bevel gear 1206 is meshed on one side of the driving bevel gear 1205, a driven shaft 1207 runs through the driven bevel gear 1206, and blocks 1204 are installed on both sides of the driving bevel gear 1205 and the driven bevel gear 1206;

[0035] There are two groups of stoppers 1204, each group of stoppers 1204 has two stoppers, and the cross-sections of the two groups of stoppers 1204 are both annular;

[0036] The driving bevel gear 1205 and the driven bevel gear 1206 have the same size and shape, and the moving directions of the driving bevel gear 1205 and the driven bevel gear 1206 are opposite;

[0037] The outer side of the stirring mechanism 12 is evenly provided with stirring blades 14, and the top of the radiator 5 is provided with a heat sink 13;

[0038] Specifically, Figure 1 , Figure 4 and Figure 5 As shown, when in use, by starting the stirring motor 1202, the active bevel gear 1205 is driven to rotate under the action of the stirring shaft 1203, and then the driven bevel gear 1206 is driven to rotate synchronously, and then the driven shaft 1207 is driven to rotate. The stirring shaft 1203 and the driven shaft 1207 rotate, thereby driving the stirring blade 14 to rotate synchronously, so that the water inside the radiator 5 flows, thereby increasing its heat dissipation effect.

[0039] Working principle: When the utility model is in use, firstly, by providing a heat-conducting frame 4, the four sides of the microwave power amplifier body 3 can be completely contacted together, so as to absorb the heat around the microwave power amplifier body 3, and the absorbed heat is conducted to the inside of the radiator 5 through the heat-conducting frame 4, and the stirring motor 1202 is started during the conduction to drive the stirring shaft 1203 to rotate, and the stirring shaft 1203 drives the driving bevel gear 1205 to rotate synchronously while the stirring shaft 1203 rotates, and because the driving bevel gear 1205 and the driven bevel gear 1206 are meshed with each other, the driving bevel gear 1205 drives the driven bevel gear 1206 to rotate synchronously while the driving bevel gear 1205 rotates, thereby driving the driven shaft 1207 to rotate, and by providing a stopper 1204, the moving driving bevel gear 1205 and the driven bevel gear 1206 can be limited, so as to prevent the driving bevel gear 1205 and the driven bevel gear 1206 from rotating. The movable bevel gear 1205 and the driven bevel gear 1206 are offset in position during the long-term movement, which affects the subsequent operation. The stirring shaft 1203 and the driven shaft 1207 rotate and drive the stirring blade 14 to rotate synchronously, thereby stirring the water inside the radiator 5, so that the water inside the radiator 5 flows, thereby increasing its heat dissipation effect. When the water inside the radiator 5 is heated, it will change from liquid to gas. When the gaseous water contacts the heat sink 13, it will release heat and condense into liquid again. The heat sink 13 will conduct the heat to the inside of the shell 1. By starting the heat dissipation fan 18, the heat dissipated from the heat sink 13 to the inside of the shell 1 is discharged through the air. By providing the air guide 11 and the air inlet 17, the air inside the shell 1 can be exchanged with the outside air under the action of the heat dissipation fan 18, thereby improving the heat dissipation effect of the microwave power amplifier body 3.

[0040] Then, the activated carbon protection plate 10 is pushed to be inserted between the two blocks 7. During the insertion process, the adjusting rod 608 is pulled to drive the movable block 602 to slide inside the guide groove 606. The guide groove 606 can be provided to limit the moving movable block 602 to prevent the movable block 602 from being offset in the process of movement, thereby affecting subsequent operations. While the movable block 602 moves horizontally, it squeezes the squeezing spring 607 on the one hand, so that the squeezing spring 607 is compressed by the squeezing force, and on the other hand, it drives the limit block 605 to make synchronous horizontal movement, so that the limit block 605 is retracted into the fixed block 601, until the activated carbon protection plate 10 is completely inserted into the two blocks 7. Inside, the adjusting rod 608 is immediately released, so that the force on the extrusion spring 607 disappears, thereby pushing the movable block 602 to make horizontal movement, and the movable block 602 drives the limit block 605 to make synchronous horizontal movement while making horizontal movement, until the limit block 605 passes through the through hole 603 and is inserted into the inside of the limit groove 604. Through the above operation, it is convenient to limit the activated carbon protective plate 10, so that the activated carbon protective plate 10 is installed on one side of the air guide port 11. By providing the activated carbon protective plate 10, external dust and small insects can be prevented from entering the interior of the shell 1 through the air guide port 11, thereby reducing the influence of dust and small insects on the microwave power amplifier body 3, and then improving the service life of the microwave power amplifier body 3.
