This creation is a kind of lift crown prince building,Include a bottom frame,One ceiling frame,One transmission group and a sensing group,Wherein: its top of the bottom frame is equipped with a port； Its group of the ceiling frame sets the port of the what bottom frame,The ceiling frame includes the ceiling that plural lifting sleeve and one group set what lifting sleeve top； The transmission system group sets the what bottom frame,It includes a driving source and plural drive assemblies,The driving source frenulum moves drive assemblies operating,And the drive assemblies frenulum moves lifting sleeve axial displacement； The sensing system includes the rising sensor of induction detecting ceiling frame lifting position,And one induction detecting ceiling frame down position decline sensor； Accordingly,Transmission group drives the lifting running of ceiling frame in closed state in the inside and outside air-flow of unlatching port guiding or closing port,And rising or falling for ceiling frame incudes the running detected its position and stop transmission group by rising sensor and decline sensor respectively.本創作是一種升降式太子樓，包括有一底棚架、一頂棚架、一傳動組及一感測組，其中：該底棚架其頂部設有一通口；該頂棚架其組設於該底棚架之通口，該頂棚架包括有複數升降套管及一組設於升降套管頂端之頂棚；該傳動組係組設於該底棚架，其包括有一驅動源及複數傳動套件，該驅動源係帶動傳動套件運轉，而該傳動套件係帶動升降套管軸向位移；該感測組係包括有一感應偵測頂棚架上升位置之上升感測器，及一感應偵測頂棚架下降位置之下降感測器；據此，傳動組帶動頂棚架之升降運作呈開啟通口導引內外氣流或封閉通口呈關閉狀態，且頂棚架之上升或下降分別由上升感測器及下降感測器感應偵測其位置而停止傳動組之運作。
