[0002] Ship is the general term of various ships, and it is a vehicle capable of sailing or berthing in water area for transportation or operation. It has different technical performances, equipment and structural types according to different use requirements. The ventilation and air exchange device in the ship engine room is an important part of the ship. Therefore, it is necessary to explore the ventilation and air exchange device of the ship. In the prior art, because there are suspended dust and particulate matters in the air, a filter screen is usually arranged inside the ventilation device to filter the impurities in the air, so as to ensure the air quality. However, when the filter screen is used for a period of time, the impurities accumulated on the filter screen will affect the air quality, so that the air quality in the ship engine room is poor, which affects the ventilation and exhaust effect in the ship.

[0013] Further, the shell is internally hollow, one side of the shell is provided with an air inlet part, and the other side of the shell is provided with an air outlet part.

[0014] Compared with the prior art, the device has the following beneficial effects: the device has simple structure, reasonable design and convenient use. The fan in the shell rotates and inhales external air, so that the external air is output to the ship engine room through the air inlet part, the shell interior and the air outlet part, and then enters the ship engine room. The entering air is filtered through the filter screen, thereby ensuring the ventilation and exhaust effect. After a period of use, a large amount of dust and suspended particles are attached to the surface of the filter screen. At this time, the motor drives the winding wheel to rotate, the winding wheel pulls the reciprocating block to move up and down along the guide rod, and the cleaning roller cleans the surface of the filter screen, thereby avoiding the problem that the dust and suspended particles block the filter screen plate and cannot be cleaned, thereby affecting the ventilation and exhaust of the device and the air quality in the ship engine room, and improving the ventilation effect of the ship engine room.
