When the first cooling cylinder 21 rotates until the balls on one of the abutting blocks 217 are in contact with the pressing arc plate 219, the pressing arc plate 219 generates rightward thrust force on the abutting block 217, the abutting block 217 drives the blocking block 215 to move rightward through the vertical plate 216, the ventilation groove 211 is communicated with the annular groove 212, the air pump 213 can send cooling air into the annular groove 212 and the ventilation groove 211, and finally the cooling air is blown out from the air blowing port 214, and the heat dissipation inside the first cooling cylinder 21 can be accelerated in an air cooling mode due to the highest temperature inside the first cooling cylinder 21, so that the cooling efficiency is improved. When the first cooling cylinder 21 continues to rotate, the balls on the abutting blocks 217 are separated from the extrusion arc plate 219, the abutting blocks 217 are not pushed any more, the vertical plates 216 drive the blocking blocks 215 to reset leftwards under the action of spring force, the blocking blocks 215 block the ventilation grooves 211, the air pump 213 cannot transmit cooling gas to the ventilation grooves 211 through the annular grooves 212, namely, the air blowing ports 214 only blow out the cooling gas when the ventilation grooves 211 rotate above the first cooling cylinder 21, so that the cooling gas cannot be mixed in cooling water, an effective air cooling effect cannot be achieved, and the problem of energy consumption waste is caused. When the upper ventilation groove 211 is rotated to communicate with the annular groove 212, the lower ventilation groove 211 is blocked, and the two ventilation grooves 211 are alternately opened.
In order to prevent cooling water from entering the ventilation groove 211 from the lower air blowing opening 214 and then entering the air pump 213 through the annular groove 212, affecting the normal operation of the air pump 213, a one-way valve may be installed in the air outlet of the air pump 213.
