The main purpose of the air pipe head is to regulate and maintain the air pressure inside the cabin, prevent foreign objects from entering, and balance the pressure difference. ‌

Air ducts, especially in marine environments, play an important role. They help the air pressure inside the cabin to approach atmospheric pressure through inhalation and respiration, thereby maintaining it within the designed pressure of the cabin. This design not only prevents external factors such as seawater, rainwater, and Mars from entering, but also prevents ocean waves and debris from entering the cabin through the ventilation pipe. In addition, the air tube head can effectively balance the pressure difference
