Description

Technical Field

[0001] The utility model relates to the technical field of solution preparation, in particular to a solution preparation device. Background Art

[0002] Disinfection is one of the important means of epidemic prevention. It is usually necessary to pay attention to the correct selection and use of disinfectants, ensure the accuracy and disinfection effect of their concentration and active ingredients, reasonably arrange the use time and amount, and strictly control the methods and processes to ensure public health and safety.

[0003] Alcohol disinfectant and 84 disinfectant are commonly used disinfectants for epidemic prevention. Taking 84 disinfectant as an example, you need to pay attention to its effective chlorine concentration when using it. Effective chlorine is an effective bactericidal component and an important indicator for measuring the bactericidal ability of disinfectants. According to relevant regulations, the most common concentration of chlorine-containing disinfectants used by the public at home and in offices is generally 500mg / L to 1000mg / L of effective chlorine. The effective chlorine concentration of the original solution of 84 disinfectant is usually 5%, equivalent to 50000mg / L. When wiping or soaking items used on the surface of objects that are in daily contact for preventive disinfection, a concentration of 500mg / L can be used. Therefore, when using the original solution of 84 disinfectant for disinfection, it needs to be diluted to a ratio of 1:100.

[0004] Currently, when preparing solutions of precise concentrations, multiple beakers and precise measuring tools are required for precise measurement before mixing. For example, measuring tools include graduated cylinders and electronic scales. Both the measurement and mixing processes require manual operation, which is not only cumbersome but also prone to errors. In addition, manual stirring during mixing can easily cause accidental incidents such as splashing or spilling of the solution. Utility Model Content

When the solid solute meets the set weight, the control board 11 controls the driving member 53 to drive the rotating plate 54 to rotate, and pours the solid solute in the second container 56 into the second funnel 52.
