The utility model relates to a scrapper structure improvement.The fan-shaped buckle groove hole is closed between the assembly groove and the oil volume chamber by the seat body of the sealing soft rubber seat.Only the scrapping oil in the oil volume chamber is allowed to be led from the infusion through-hole to the collecting tank chamber.And then through the perforations of liquid through holes and special-shaped soft films,It is the only function released from the outlet hole.So that the scraping part assembly joint is pivoted in the assembly groove of the bottle cap.The use of seals can be omitted.When the scrapping parts are opened or closed by the liquid through hole on the bottle cap, they can be turned to swing.To achieve a more labor-saving or smoother operation.一種刮痧器結構改良，係藉由止密軟膠座的座體在組接凹槽與油液容室間將扇形扣接槽孔封閉，只允許油液容室內的刮痧油液從輸液通孔導引至集液槽室，再經由通液孔及異形軟膠片的穿孔，而僅唯一從出液孔釋出的作用，俾使刮痧件組接頭在瓶蓋的組接凹槽內樞設，可以省略密封件的使用，並使刮痧件在瓶蓋上作通液孔打開或關閉轉擺操作時，達到操作較為省力或更為順暢的效果。
