The present invention provides a use of a spring check valve in an inflatable structure to adjust the gas in the inflatable structure to improve the sleep quality of the human body. The inflatable structure includes: two pillow bodies, each pillow body has a gas-filled area inside, and a spring check valve is arranged on the pillow body and communicates with the gas-filled area； and two seals of a removable closed check valve cover. The spring check valve includes a fixing seat and a stop piece. The fixing seat is arranged on each pillow body, and the fixing seat has a through hole connected to the gas filling area. The stopping piece is located in the gas filling area and is partially connected to the fixing seat to prevent The baffle movably closes the through hole. The use of the spring check valve in the inflatable structure of the present invention can improve the sleep quality of the human body, and can also promote the blood circulation of the human body during sleep, thereby preventing the human body from snoring and respiratory arrest during sleep.本發明提供一種使用彈簧逆止閥於充氣結構體中之用途，用於調整在充氣結構體中的氣體以改善人體之睡眠品質。充氣結構體包括：兩枕墊體，每一枕墊體內部具有氣體填充區，且彈簧逆止閥設置於枕墊體且與氣體填充區連通；以及可卸除的封閉逆止閥之兩封蓋。彈簧逆止閥包括固定座及止擋片，固定座設置於每一枕墊體，且固定座具有通孔連通於氣體填充區，止擋片位於氣體填充區且部分連接該固定座，使止擋片活動地封閉通孔。本發明的使用彈簧逆止閥於充氣結構體中之用途可改善人體之睡眠品質，更可促進人體睡眠時之血液循環，進而防止人體在睡眠時之打鼾及呼吸中止症。
