[0001] The utility model relates to the technical field of medicine-adding boxes, in particular to a pH value automatic regulating device for a spray medicine-adding box. Background Art

[0002] At present, the pH value adjustment inside the existing dosing box mostly requires manual adjustment. During the adjustment, it is often necessary to weigh the acid or alkali solution according to the demand and then add it. After the addition is completed, it is stirred and mixed and finally the pH value is tested. This adjustment method through manual addition and weighing is not only prone to errors, but also has relatively low efficiency, and thus has certain shortcomings. For this reason, we propose an automatic pH value adjustment device for a spray dosing box. Utility Model Content
