This creation provides a curing device for use with a waste liquid collection container, which includes a containing body and an operating member. The containing body has a containing chamber for containing a curing agent, and has a through hole at the bottom. The operating member can be movably combined with the accommodating body, and the operating member passes through the accommodating chamber and is connected to a plug body. The plug body normally plugs the through hole. When the operating member is driven, the plug body moves away from the through hole The curing agent contained in the chamber leaks out through the through hole and is directly filled into the inside of the waste liquid collection container, so that the waste liquid is solidified and is beneficial to transportation and destruction treatment.本創作提供一種配合廢液收集容器使用之固化裝置,其包含一容置體和一操作件,容置體具有一供固化劑容裝之容室,且於底部具有一通孔。操作件可活動地結合於容置體,操作件並穿經容室而連著一塞體,塞體在常態時是塞住通孔,隨著操作件被驅動而連動塞體離開通孔時,容室內所容裝的固化劑即由通孔漏出,並直接填入所述廢液收集容器之內部,以使廢液固化而有利於搬運和銷毀處理。
