The utility model relates to a structure of a rotary suction connecting pipe. The main structure comprises a suction component, and a suction inlet and a suction outlet are respectively arranged at two sides of the suction component facing away from each other, and the suction component defines mutually An inlet passage and an outlet passage are connected, wherein the inlet passage is in communication with the suction inlet, the outlet passage is in communication with the suction outlet, and the cross-sectional area of the outlet passage is smaller than the cross-sectional area of the inlet passage, and the suction member is further provided with an installation The sleeve portion and a guiding slope are formed by extending from the lower side of the inlet passage toward the outlet passage. With the above structure, the user can use the mounting socket to sleeve an electric burner or an auxiliary rod body, and connect a suction device through the connecting tube at the outlet passage to suck liquid or smoke with the suction member, and cooperate with the guide. The inclined surface achieves a fast attracting effect.本新型為有關一種迴旋式抽吸連接管之結構，主要結構包括一抽吸元件，抽吸元件相互背離之兩側處分別設有一抽吸入口及一抽吸出口，抽吸元件內界定有相互連通的一入口通道及一出口通道，其中入口通道與抽吸入口相連通，出口通道與抽吸出口相連通，且出口通道之截面積小於入口通道之截面積，抽吸元件上還設有一安裝套接部及一導引斜面，導引斜面由入口通道下側處往出口通道之方向延伸形成。藉上述結構，使用者可利用安裝套接部套接一電燒刀或一輔助桿體，並於出口通道經由連接管連接一抽吸裝置，以利用抽吸元件吸取液體或煙霧，並配合導引斜面達到快速吸引的效果。
