摘要：
This creation provides a vent valve for the exhaust column of the negative pressure cupping cup. The upper round top of the cup body is provided with a vent column and an exhaust column projecting outward, and the exhaust column is formed to communicate the internal and external rows of the cup body itself. Piston-shaped air relief valve is installed in the air hole and exhaust column. The design of the relief valve in this creation allows the user to use the relief valve to block the exhaust hole in the exhaust column so that there is no outward flow of gas in the cup to achieve the cupping effect. It circulates in the cup body to achieve the effect of reducing the vacuum degree, avoiding the user's operation mistakes and the excessive vacuum pressure of the modeling injury.本創作提供負壓拔罐杯體排氣柱用洩氣閥，杯體的上圓頂部設有向外凸出一通氣柱和一排氣柱，排氣柱內形成有連通杯體本身內部和外部排氣孔，排氣柱內安裝活塞形洩氣閥。本創作中洩氣閥設計，讓使用者使用時該洩壓閥堵住排氣柱內該排氣孔使杯體內氣體無向外流，達到拔罐效果，當真空度過量拉動洩壓閥，使外部空氣流通於杯體內達到真空度降低的效果，避免使用者的操作失誤造型真空壓力過大受傷。
