In the practical application process, the specific shape and specific position of the ventilation air duct can be determined according to practical situations, for example, the ventilation air duct can be arranged in an extending manner up and down or in a front-back extending manner. The first air port 101 is in communication with the outside, and the first air port 101 may be disposed at the rear side, the bottom, the left and right sides, etc. of the casing 1, alternatively, considering that the first air port 101 needs to be in communication with the outside, a pipe may be externally connected to the first air port 101 for penetrating through a wall or a window, so as to realize a communication function with the outside. Alternatively, the second tuyere 102 may be provided at the front face, the left and right sides, the upper and lower sides, or the like of the cabinet 1. Optionally, in this embodiment, the second air port 102 may be disposed corresponding to the air flow outlet of the fan assembly 2, so that the air flow blown out by the fan assembly 2 can be directly blown out from the second air port 102, so that the flow path of the air is reduced, and the loss of the air volume is reduced, so as to achieve the effect of increasing the fresh air volume.
