The invention includes a shell, an outlet pipe, a first container, a second container and a pressing structure.The guide pipe, the first container and the pressing structure are arranged on the shell.The outlet pipe is connected with the first container and the second container. The first container holds high-pressure fluid and is provided with a valve, which is between the first container and the outlet pipe, and the second container holds drinking liquid. The pressing structure can be moved to an original position and a lower pressure position.The original position moving to the pressing position has a first stroke, a second stroke and a third stroke.The valve body is only opened during the second stroke, so that the outlet pipe supplies high-pressure fluid to the second container.The rest of the travel and position remain closed.Therefore, this case has both the advantages of single press to achieve quantitative feeding, and mechanical design without power can be used for a long time.本創作係包括一殼體、一導出管、一第一容器、一第二容器及一按壓結構。導出管、第一容器及按壓結構設於殼體上。且導出管連結第一容器及第二容器，第一容器容納高壓流體，並設一閥，其介於第一容器與導出管之間，第二容器容納飲液；按壓結構可移動至一原始位置及一下壓位置。原始位置移動至下壓位置具有一第一行程、一第二行程及一第三行程。閥體只於第二行程內的時間開啟，使導出管對第二容器供應高壓流體。其餘行程及位置保持關閉。故，本案兼具單次按壓達成定量供料相當方便，與機械設計不需電力可長時間使用等優點。
