The liquid storage and release device comprises a tube shell (), a capsule-like liquid container (), a piercing component () and a piston rod (), wherein the tube shell () is open at one end and closed at the other end, and the interior thereof is a tube cavity (); the capsule-like liquid container () and/or the piercing component () is/are slidably arranged in the tube cavity (); one end of the piston rod () is slidably arranged in the tube cavity () of the tube shell (), and the other end of the piston rod () is provided with a liquid release opening (); and the piston rod () is provided with a liquid channel through which the liquid release opening () is in communication with the tube cavity (). When the piston rod () slides towards the interior of the tube cavity (), the capsule-like liquid container () and the piercing component () apply pressure to each other under the action of the piston rod (), so that the piercing component () pierces the capsule-like liquid container () so as to release the liquid pre-stored in the capsule-like liquid container ().
