LIQUID TRANSFER DEVICE

To provide a liquid transfer device capable of quantitatively absorbing liquid, allowing a liquid collection assembly to be replaced, and capable of reusing pressing means, and saving cost.SOLUTION: A liquid transfer device includes pressing means, a housing, a connection component, and a liquid collection assembly. The pressing means includes an extrusion unit. The housing includes a first side wall and a second top wall. The first side wall and the second top wall form a receiving cavity. The pressing means is housed in the receiving cavity. One end of the connection component is connected to a second side wall and the other end is connected to the liquid collection assembly. The liquid collection assembly includes a liquid collection pipe, a liquid collection head, and a second connection unit. The liquid collection pipe is provided corresponding to the extrusion unit by projection of the liquid collection assembly into the accommodation cavity. The pressing means reciprocates along a center axis of the accommodation cavity, the extrusion unit reciprocates with respect to the liquid collecting pipe, and the extrusion unit abuts on the liquid collection pipe to grip or release the liquid collection pipe, thereby discharging or absorbing the liquid.SELECTED DRAWING: Figure 1 【課題】液体を定量的に吸収でき、且つ液体採取アセンブリが交換可能であり、押圧手段が再利用でき、コストを節約する液体転移装置を提供する。【解決手段】 液体転移装置であって、押圧手段、ハウジング、接続部品及び液体採取アセンブリを含む。押圧手段は、押出部を含み、ハウジングは、第１側壁及び第２頂壁を含み、第１側壁と第２頂壁が収容キャビティをなし、押圧手段が収容キャビティ内に収容され、接続部品の一端が第２側壁に接続され、他端が液体採取アセンブリに接続され、液体採取アセンブリは、液体採取管、液体採取ヘッド及び第２接続部を含み、液体採取アセンブリが収容キャビティに突入することで、液体採取管が押出部に対応して設けられる。押圧手段が収容キャビティの中心軸に沿って往復移動し、押出部を液体採取管に対して往復移動させ、押出部が液体採取管に当接して液体採取管を把持又は解放し、液体を排出又は吸収させる。【選択図】図１
