Anti-drip needle

Used to prevent the liquid dripping at the filling mouth during the filling process, also known as filling the needle.

General review

Used to prevent the liquid dripping at the filling mouth during the filling process, also known as filling the needle. Because of the different surface tension of the different liquids, the inner diameter of the filling mouth requirment is different. To pure water, for example, the inner diameter less than 5mm, the water will not drip. In addition, the choice of diameter of the filling mouth is also related to the viscosity of the liquid.
