[0002] Ships are vehicles that can sail or anchor in waters for transportation or operations. They have different technical performances, equipment and structural types according to different use requirements. During navigation, the air in the cabin must be kept circulating. The cabin of a ship is a closed environment. Most ships now ventilate through windows or ventilation systems. Due to weather changes, such as rain, the noise is too loud, but the windows have to be closed, which makes the air in the ship poor, causing people to breathe poorly, and even dizziness and brain swelling. If the windows are opened, rain will drift into the ship and wet the ship. When the wind is too strong, the things in the ship will be blown into a mess, and even blown out of the ship. In addition, the wind is strong, the rain is heavy or the ship traffic is too large. The defect of the prior art is that when the ship cabin ventilation device in the prior art ventilates the interior of the cabin, the internal fan will vibrate, thereby generating a lot of noise, affecting the comfort of the passengers in the cabin, and disturbing the people who need to rest.
