Description

A kind of variable capacity formula liquid drawing device

Technical field

The utility model is related to liquid drawing device field, specifically, is a kind of variable capacity formula liquid drawing device.

Background technology

Some liquid are frequently necessary to down in life, such as fall soy sauce during cooking, or fall liquid detergent etc during laundry, People are generally difficult to the amount of the liquid required for accurately pouring out, can be inevitably more or a little less, except meeting band Come outside some unnecessary wastes, it is also possible to cause other problemses, soy sauce when especially cooking, once soy sauce is more, just The implicit salinity in dish can be caused too high, cause people to take in excessive salinity and cause the symptoms such as hypertension；Liquid detergent falls When entering excessive, it can not only increase the water consumption and number of times of rinsing, and easily drift is not washed clean, and the residual of liquid detergent is to body It is pernicious.Therefore, it is controllable to quantify that to pour out liquid be a current problem concerning life for needing to solve.

Now relatively common solution is that high scale or graticule are designed on the bottle for hold liquid, or is specially looked for One, with utensils such as graduated graduated cylinder, measuring cups, is poured into the place of needs again after measuring.But, using designing scale on bottle Or the mode of graticule, when pouring liquid, scale can not play a part of measuring, can only repeatedly incline at all in state of putting upside down A certain amount is progressively reached, complex operation step, effect is not good, easy excess；Using measuring cup, graduated cylinder, first measure and pour out again Make in this way, although possible consumption is easier control, there is also the problem of complex steps, once it is many, it is difficult to Handled, refunding former bottle may liquid in pollution bottle.

At present, there is a kind of drawing device being stuck on liquid bottle closure on the market, the drawing device is included with graduated amount of liquid Part is taken, air can be squeezed into bottle, is forced the fluid into using atmospheric pressure by repeatedly pressing the air sacculus on drawing device Part is measured, is poured out again after reaching a certain amount of.But, this kind of drawing device needs repeatedly pressing air bag, it is impossible to which a step is arrived Position, uses trouble.Moreover, it is quantitative that existing liquid, which measures part total amount taken amount, it is impossible to which regulation is, it is necessary to which moment concern is measured The amount of liquid, uses trouble.

Now need one kind to adjust and draw total amount, and liquid in place can be drawn according to the step of total amount one of drawing of setting Drawing device solves the above problems.

Utility model content

The purpose of this utility model is to design a kind of variable capacity formula liquid drawing device, adjustable with total amount is drawn, Advantage easy to operate.
