The beneficial effect achieved by the utility model is: the patent sets a ventilation mechanism, a transmission mechanism and a filtering mechanism. When the air humidity is relatively humid, the ventilation tube is driven to move by the transmission ring, and the fan is running. The air inside the ventilation square tube is extracted through the air inlet on the ventilation tube.
