The heat pipe 423 is internally provided with a heating medium, two ends of the heat pipe 423 are respectively extended to the lower end of the sealing bottom plate to be connected with a heating medium transmission pipeline, or the heat pipe 423 is connected with a heating wire for heating the heat pipe 423, so that the heat pipe 423 is in a state that water drops falling to the heat pipe 423 can be vaporized when being heated, and the heat pipe 423 is generally kept at more than 200 degrees. By heating the heat pipe 423, water droplets at the runner heat pipe 423 are formed into water vapor, which is then sucked away by the moisture-discharging pump 21, thereby realizing the effect of water-discharging-free.
