[0021] Based on the above scheme, the present application sets up an air duct assembly 3, and a fan 34 set inside the bellows 31 draws outside air from the air inlet 311 into the bellows 31, and then inputs the air into the cabin 11 through the first exhaust port 312 to meet the air flow required by the cabin 11, and inputs air into the hull 2 ​​through the second exhaust port 313 and the air outlet duct 33 to supplement the air flow required by the hull 2. By setting up one fan 34, the air flow requirements of the cabin 11 and the hull 2 ​​can be met at the same time, which not only reduces the weight of the fan 34, but also reduces the production cost and saves the space occupied by the fan 34.

[0022] like Figure 1 As shown, in order to facilitate the fan 34 to draw air from the outside, the front and rear ends of the hull 1 are the bow 12 and the stern 13 respectively, and the bellows 31 is arranged on one side of the cabin 11 adjacent to the bow 12.

[0023] like Figure 1 As shown, in order to further reduce the space occupied by the wind duct assembly 3 , an instrument panel 4 is also included. The instrument panel 4 is arranged on one side of the cabin 11 adjacent to the bow 12 , and the bellows 31 is arranged in the instrument panel 4 .

[0024] like Figure 1 As shown, in order to ensure the normal use of the hull 2 ​​, the hull 2 ​​has an inlet 21 , the inlet 21 is arranged at the head of the hull 2 ​​, and the other end of the air outlet duct 33 is connected to the inlet 21 .

[0025] like Figure 1 As shown, in some embodiments, a guide port 5 is provided at the top of the stern 13, and the interior of the cabin 11 and the interior of the hull 2 ​​are respectively connected to the guide port 5, and the guide port 5 is used to discharge gas.

[0026] like Figure 2 and Figure 3As shown, in order to facilitate the control of the air flow for the hull 2 ​​and the air flow for the cabin 11, a partition 314 is further provided inside the bellows 31, and the partition 314 extends in the horizontal direction and divides the bellows 31 from top to bottom into a first chamber 315 and a second chamber 316, and the second exhaust port 313 is provided on the top surface of the bellows 31 and communicates with the first chamber 315, and the partition 314 has a first communication port 3141 and a second communication port 3142 arranged at intervals along the horizontal direction, and the bellows 31 is provided in the second chamber 316. , and the air outlet end of the wind box 31 is connected to the first connecting port 3141, the air inlet 311 is provided at the side of the wind box 31 and is connected to the second chamber 316, one end of the air inlet duct 32 extends from the air inlet 311 into the second chamber 316 and is connected to the fan 34, the first exhaust port 312 is provided at the bottom surface of the wind box 31 and is connected to the second chamber 316, and one end of the air outlet duct 33 extends from the first exhaust port 312 into the second chamber 316 and is connected to the second connecting port 3142;

[0027] By setting the partition 314, the bellows 31 is divided into a first chamber 315 and a second chamber 316, and air is supplied to the hull 2 ​​and the cabin 11 respectively through the second connecting port 3142 and the first exhaust port 312, so as to effectively separate the air for the cabin 11 from the air for the hull 2, thereby ensuring that the air flow rate for the hull 2 ​​and the air flow rate for the cabin 11 can meet the needs, and the ratio of the air flow rates can be controlled by controlling the size ratio of the second connecting port 3142 and the first exhaust port 312.

[0028] In some embodiments, the partition plate 314 can be detachably mounted on the wind box 31 to control the ratio of the second communication port 3142 and the first exhaust port 312 .

[0029] like Figure 2 As shown, in order to further control the air flow for the hull 2 ​​and the air flow for the cabin 11, the first exhaust port 312, the first connecting port 3141 and the second connecting port 3142 are spaced apart along the horizontal direction to prevent the first exhaust port 312 and the second connecting port 3142 from affecting each other.

The direction of the incoming wind is ensured by controlling the shape of the air outlet duct 33 to avoid affecting the use of the hull 2.

[0032] In summary, an embodiment of the present invention provides a ship with a hull 2, which, by providing an air duct assembly 3, has a fan 34 provided inside the bellows 31 to draw outside air from the air inlet 311 into the bellows 31, and then inputs the air into the cabin 11 through the first exhaust port 312 to meet the air flow required by the cabin 11, and inputs air into the hull 2 ​​through the second exhaust port 313 and the air outlet duct 33 to supplement the air flow required by the hull 2. By providing one fan 34, the air flow requirements of the cabin 11 and the hull 2 ​​can be met at the same time, which not only reduces the weight of the fan 34, but also reduces the production cost and saves the space occupied by the fan 34.
