[0002] Quantitative dosing devices are widely used in laboratories of hospitals, colleges and universities, scientific research institutions, etc. to continuously and quantitatively dosing various test solutions, radioactive isotopes, biological agents, etc. during chemical analysis tests. In addition, it is also suitable for quantitative filling of hospital preparation rooms, ampoules, eye drops, various oral liquids, shampoos and various aqueous solutions. It is especially suitable for liquid packaging in large, medium and small pesticide factories.

[0003] The quantitative liquid adder uses the reciprocating motion of the plunger of the syringe barrel and two one-way pistons to make the liquid move quantitatively and directionally for adding liquid. The built-in liquid adder consists of a liquid storage bottle and a liquid adder. The liquid adder is a plastic screw-mouth bottle cap, which is connected to the syringe barrel with an outlet pipe and an inlet pipe equipped with a one-way piston to control the inflow and outflow of the test solution. There is a positioning stem with a metal scale mark and a movable positioning sleeve on the top of the bottle cap to control the accuracy of the amount of test solution added. The external liquid adder is a syringe barrel with an outlet pipe and an inlet pipe with a one-way automatic piston, a positioning stem with a scale mark, and a positioning sleeve installed together.

[0004] When adding liquid, the bottom of the existing liquid adder is installed with the bottle body through a threaded sleeve. However, since the top diameters of different bottles are different, when sucking liquid from different bottles, threaded sleeves of different diameters are required for installation. In this case, it is necessary to adapt to multiple different threaded sleeves. These threaded sleeves are all single structures, which are very inconvenient to use and need to be improved.
