The invention relates to the technical field of seats, in particular to a ventilation device, a seat and a ventilation method. The ventilation device comprises a ventilation pad, a ventilation pipe, an air source and a controller. The ventilation pad comprises a sealing sleeve and a ventilation interlayer, the sealing sleeve is provided with a plurality of first ventilation holes and at least one second ventilation hole, and the ventilation interlayer is wrapped in the sealing sleeve. The ventilation pipe comprises a contraction section, a throat section and an expansion section which are sequentially connected, and the end, deviating from the throat section, of the contraction section communicates with the second ventilation hole. One end of the guide pipe is arranged in the contraction section, and the port of the guide pipe faces the expansion section. The air source is used for providing continuous airflow and communicated with the other end of the guide pipe, and the controller is used for controlling connection and disconnection of an air path between the air source and the guide pipe. Through the mode, the heat dissipation effect of the seat is enhanced, the heat dissipation efficiency of the seat is improved, and the seat is rapidly cooled.
本申请涉及座椅技术领域,尤其涉及一种通风装置、座椅及通风方法。通风装置包括通风垫、通风管、气源和控制器。通风垫包括密封套和透气隔层,密封套开设有多个第一通风孔和至少一个第二通风孔,透气隔层被包裹于密封套内部。通风管包括依次连接的收缩段、喉段和扩张段,收缩段背离喉段的一端与第二通风孔连通。通风管还包括导管,导管一端设置于收缩段内且其端口朝向扩张段。气源用于提供连续气流,气源与导管另一端连通,控制器用于控制气源与导管之间气路的通断。通过上述方式,有利于增强对座椅的散热效果,提升座椅的散热效率,使座椅快速降温。
