Further, two sets of guide plates 25 are oppositely arranged on one side surface of the partition plate 21, which is close to the main body 1 of the device, and the guide plates 25 are obliquely arranged towards the middle of the through groove 24.

The specific application embodiment of the utility model is as follows:

the air outlet pipe 11 is connected with the air outlet of the equipment main body 1, and the impeller in the equipment main body 1 drives the air entering from the air inlet to be discharged through the air outlet pipe 11, and the air outlet pipe 11 is close to the first reflux groove 2 arranged on one section of the equipment main body 1, so that condensate reflux generated due to overlong air outlet pipe 11 is blocked and collected. And the condensate collected in the first reflux groove 2 is discharged into the air outlet pipe 11 through a drain pipe 12 which is arranged at the bottom of the first reflux groove 2 and is communicated with the outside of the air outlet pipe 11. Avoiding the condensate water from remaining in the air outlet pipe 11 to form scale.

When the centrifugal fan is in operation, the partition plate 21 hinged with the first backflow groove 2 rotates towards a direction away from the device main body 1 under the action of wind force, so that air flow can be discharged from the device main body 1 through the air outlet pipe 11. When the centrifugal fan stops running, the baffle 21 covers the air outlet pipe 11, and condensate is prevented from flowing back along the air outlet pipe 11.

The first elastic member 22 may be made of a torsion spring. The first elastic piece 22 is arranged between the inner wall of the air outlet pipe 11 and the partition plate 21, and pushes the partition plate 21 to rotate and return to a position covering the air outlet pipe 11 when the centrifugal fan stops blowing air. The abutment block 3 is provided on the side of the partition plate 21 close to the apparatus main body 1, and limits the position when the partition plate 21 covers the air outlet duct 11.
