Saline-sugar solution concentration regulating method based on intelligent cup used for kitchen

Abstract

The invention discloses a saline-sugar solution concentration regulating method based on an intelligent cup used for a kitchen, relating to the field of kitchenware. The method includes firstly collecting an offset distance D, on a second light receiving module, of first light emitted by a first light emission module after the first light is reflected by a first accommodating chamber of the intelligent cup; solving the refractive index n of a solution according to the offset distance D, a first distance L and a first angle of incidence [theta]i; acquiring the concentration c of the solution according to the refractive index n of the solution, solute information of the solution, and a solvent of the solution; and finally sending a control instruction to a water feeding control valve according to a relationship between the solution concentration c and a solution target concentration value c<goal>. The method avoids precision requirements on solution ratios in weighing methods, improves the accuracy of the concentration of a prepared solution, and does not need manual conversion to solve the concentration like weighing methods. The concentration of the solution can be acquired again after evaporation or addition of an indefinite quantity of a material.

Description

technical field [0001] The invention relates to the field of water cups, in particular to a method for controlling the concentration of salt water and sugar water based on a kitchen smart water cup. Background technique [0002] In daily life, human beings often drink sugar water, prepare physiological saline, or prepare salt water with seawater concentration so that the ocean can spit fresh sand. [0003] In the prior art, sugar water and salt water are usually prepared by weighing method, but in fact, the amount of solution generally available at home is not large. The concentration of the solution is not easy to be accurate. On the other hand, if the accuracy of the weighing method is reduced by increasing the solvent and solute, it will easily cause waste of water resources and solute. [0004] In addition, the weighing method also has the following problems: 1), it is necessary to manually convert the solute volume to solve the concentration; 2), due to evaporation or ...
