[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilation and drainage device for HVAC equipment, comprising: an outer wall of the HVAC equipment, and a positioning plate disposed on the right side of the outer wall of the HVAC equipment, wherein a shell is disposed on the right side of the positioning plate, a drainage interface is disposed on the inner side of the outer wall of the HVAC equipment, and a drainage pipe is disposed on the right side of the drainage interface, wherein a rubber ring is disposed in the middle of the drainage pipe, and further comprising:

[0007] A limiting component is installed on the lower left side of the housing, and a drive motor is provided on the upper side of the housing. The lower end of the drive motor is connected to a first drive disk, and a first support frame is provided on the lower end of the first drive disk. A second drive disk is provided on the outer side of the first drive disk, and a support block is provided on the outer side of the second drive disk. A fan blade is provided on the outer side of the support block, and connecting blocks are provided on the left and right sides of the support block.

[0009] In one possible implementation, the limiting rod is engaged with both the connecting rod and the housing, and the connecting rod is threadedly connected to the limiting block.

[0010] In one possible implementation, the limiting block and the guide plate are slidably arranged relative to each other, and the limiting block and the positioning plate are engaged relative to each other.

[0011] In one possible implementation, the first drive disk and the second drive disk are meshed relative to each other, and the second drive disk is symmetrically arranged about the central axis of the first drive disk.

[0012] In one possible implementation, the fan blade and the support block are engaged relative to each other, and the support block is symmetrically arranged about the central axis of the fan blade.

[0013] In one possible implementation, the connecting block is rotatably arranged relative to the second support frame, and the longitudinal section of the connecting block has a "T" shaped structure.
