[0035] The heat conducting block 22 is internally rotatably connected with an exhaust fan 24, the input end of which is connected to the circuit board, and contacts the electronic components through the heat conducting block 22, so that the heat inside the electronic components can be introduced into the position of the heat conducting block 22. At the same time, after the exhaust fan 24 is turned on, the heat introduced by the heat conducting block 22 can be discharged, so that the circuit board can be cooled;

[0036] At the same time, a positioning plate 26 is fixedly installed on the sealing plate 21, and a conical tube 25 is clamped inside the positioning plate 26. At the same time, the conical tube 25 is divided into a first part with a large diameter and a second part with a gradually reduced diameter. Two groups of air ducts 28 are installed on one side of the second part of the conical tube 25. At the same time, an air outlet 14 is fixedly installed on one end of the table 11 close to the air duct 28, so that part of the hot air blown out by the exhaust fan 24 will enter the conical tube 25, and then will be blown into the inside of the two groups of air ducts 28 and the air outlet 14 respectively, so that the hot air can enter the cab through the air outlet 14, thereby slightly increasing the temperature inside the cab, thereby achieving recycling;
