The invention relates to a fixed part at the top of a main shell which is provided with a fishing line for tying.There is a secret room that can be opened inside.For installation of inner tank,In which the actuator and the main engine board,The main shell is further provided with a material inducing opening which is connected with the chamber.Fish can be filled in the inner tank.A spray head which is closely connected with a material inducer mouth is installed.The main shell is also relatively fixed with a counterweight.It is used to sink the material inducer of the main shell into the water.The actuator is opposite to the nozzle.Until the mainboard system can automatically act the actuator according to the set time parameter,Enable the actuator to press the nozzle regularly.The time of controlling the inner canister to export the bait essence to the mouth of the sink in the water.Accordingly,The invention can intermittently control the bait mouth to output fish flavor in time in water.In order to achieve the largest bait with the least fish flavor.本發明係於一主殼頂端設有供釣線繫結之固定部，其內部界定有一可開啟之密室，用以安裝內罐、致動器及主機板於其中，主殼另設有一連通密室之誘料口；內罐充填有誘魚香精，更安裝有一密接誘料口之噴頭；該主殼另相對固定有一配重，用以使主殼之誘料口沉入水中；致動器係與噴頭相對，至於主機板係能依設定時間參數而自動作用致動器，令致動器能定時按壓噴頭，以控制內罐對沉入水中誘料口輸出誘魚香精之時機，據此，使本發明能間歇式的控制誘料口於水中定時輸出誘魚香精，以達到以最少的誘魚香精獲得最大的就餌效果。
