The invention relates to the technical field of ships, in particular to a novel mushroom type ventilator for a ship, and the ventilator comprises an air cap; a water blocking coaming is fixedly weldedto the periphery of the edge of the bottom end of the air cap, an air duct body is inserted into the bottom end of the air cap, a residue discharging pipe is installed on one side of the outer wall of the bottom end of the water blocking coaming, and the water blocking coaming communicates with the residue discharging pipe; the outer wall of the residue discharging pipe is sleeved with a residuedischarging pipe support, and the residue discharging pipe support is fixed to one end of the outer wall of the air duct body. The invention aims at designing a new mushroom type ventilation cap form,the principle is that a circle of water blocking coaming is additionally arranged on the edge of the air cap, a circle of groove is formed between the water blocking coaming and the air cap, seawateror rainwater on the outer wall of the air cap just falls into the groove after flowing down along the air cap, and the situation that the seawater or the rainwater is possibly blown into the air capby strong wind is avoided; meanwhile, the accumulated water in the groove can be discharged to the deck surface through the residual discharge pipe, so that the ventilation and exhaust quality of theresidential area is guaranteed.

    本发明涉及船舶技术领域,尤其涉及一种新型船用菌菇式通风筒,包括风帽,所述风帽的底端边缘四周固定焊接有拦水围板,所述风帽的底端插接有风筒本体,所述拦水围板的底端外壁一侧安装有放残管,所述拦水围板与所述放残管贯通,所述放残管的外壁套接有放残管支架,所述放残管支架与所述风筒本体的外壁一端固定。本发明的目的在于设计一种新的菌菇式通风帽的形式,其原理为在风帽的边缘增加一圈拦水围板,与风帽间形成一圈凹槽,风帽外壁的海水或雨水沿风帽流下后正好落入凹槽中,避免了可能被大风吹入风帽内的情况,同时凹槽内的积水可以通过放残管排出到甲板面上,以此保证居住区通排风的质量。
