A baffle 194 is provided at one end of the outer tube body 191 located on the outer wall of the outlet pipe 19, and the baffle 194 is connected to a guide rod 195, and the guide rod 195 is located inside the inner tube body 192, and a spring 196 is provided on the guide rod 195, and one end of the spring 196 is connected to the guide rod 195, and the other end is connected to the inner wall of the inner tube body 192. A sealing ring 197 is provided on one side of the baffle 194 close to the air outlet pipe 19 . The sealing ring 197 is made of rubber and can shield and seal the channel 193 .

[0040] During the drying process, when the gas containing a large amount of water vapor is discharged through the air outlet pipe 19, when the water vapor meets the air outlet pipe 19 to form condensed water, the condensed water flows downward along the air outlet pipe 19 to the cavity formed by the baffle 21 and the air outlet pipe 19. The baffle 21 prevents the condensed water from dripping into the box body 1, and prevents the Chinese herbal medicine slices from re-wetting the Chinese herbal medicine slices. When the water accumulation in the baffle 21 increases, the channel 193 is connected to the bottom of the baffle 21, the water pressure increases, and the water pressure in the channel 193 also increases, pushing the baffle 194 outward, and the spring 196 is stretched. It should be understood that the spring 196 is a stretching spring 196, the sealing ring 197 is separated from the channel 193, and the accumulation of the baffle 21 Water flows into the collecting pipe 20 through the channel 193 for collection. A drain port is provided at the bottom of the collecting pipe 20, through which condensed water is discharged to the outside to prevent it from flowing back into the box body 1 and affecting the drying efficiency. When the accumulated water in the baffle 21 decreases and the tension of the spring 196 is greater than the water pressure, the tension spring pulls the baffle 194 so that the sealing ring 197 on the baffle 194 seals and blocks the channel 193 to prevent gas from escaping from the channel 193. When there is no accumulated water in the baffle 21, when the airflow flows in the air outlet 19, the air outlet 19 is in a negative pressure state, and the baffle 194 is affected by the atmospheric pressure, so that the sealing ring 197 presses the channel 193 to prevent air leakage from the channel 193.
