Description

A kind of metering spoon

Technical field

The utility model relates to a kind of metering spoon.

Background technology

In daily life, the weight of weighing small amount of matter is common, and what of the condiment amount that institute should add when the various food of culinary art modulation are particularly perhaps limited the quantity of and take food the patient of salt to the metering of the required salt of every meal, and particular importance seems.

But in actual use, common way is will be measured to relay on balance or other measurement instruments after thing absorbs with spoon to take by weighing the very loaded down with trivial details inconvenience of such metering process again.

Granted publication number has just been announced a kind of metering spoon for the Chinese utility model patent of CN 86206194, this metering spoon comprises the spoon bar that has the spoon head, handle case with the hinge joint of spoon bar, handle cover, in handle case, be provided with the liquid capsule that is with band look liquid, the transparent tube that communicates with the liquid capsule, elastic steel sheet, the scale that shows weight is arranged on transparent tube or the handle case, handle case is balance pivot with the anchor point of spoon bar, the weighing principle of this metering spoon is as follows: when weighing, the spoon head is pressed down by gravity, the other end then upwarps, compressing liquid capsule and elastic steel sheet, colored liquid in the liquid capsule is entered in the transparent tube, thereby realize weighing, and when no weight, the weight of spoon head obtains balance by elastic steel sheet.

But weighing of above-mentioned metering spoon is subjected to the restriction of colored liquid weight in the liquid capsule, can only weigh to the object of some little quality; In addition, when using for a long time, because the liquid capsule is often oppressed, damage easily, in case the liquid capsule damages, so above-mentioned metering spoon will lose the effect of weighing; Moreover the weight of the object of being weighed shows that by scale because the weight of the object of being weighed itself is just low weight, everyone reads scale and has error easily, so weighing of the metering spoon of above-mentioned patent is accurate inadequately.

The utility model content

Technical problem to be solved in the utility model provides a kind of metering spoon accurate, easy to use, simple in structure of weighing.
