Document Type and Number:
WIPO Patent Application WO/2021/121147
Kind Code:
A1
Abstract:
Provided is a quantitative sampling dropper, comprising a suction tube (1) and an air bag (2) arranged at the top of the suction tube (1), wherein the upper end of the suction tube (1) extends into the inside of air bag (2) and a liquid storage tank (3) is formed in the space of the air bag (2) below the top of the suction tube (1); the suction tube (1) extends into the inside of the air bag (2), so that part of the space of the air bag (2) is below the top of the suction tube (1) to form the liquid storage tank (3), when a liquid is taken, the suction tube (1) is firstly filled with the liquid, then the liquid enters the liquid storage tank (3). Therefore, the liquid level in the air bag (2) is lower than the top end of the suction tube (1) when the liquid is taken, and thus, when the liquid in the dropper is discharged, only the liquid in the suction tube (1) is discharged, and the liquid in the liquid storage tank (3) does not flow out, so that quantitative liquid adding is achieved.
