Abstract
A liquid storage box, an additive dispensing apparatus, and a method for identifying an additive type. The liquid storage box is provided with a closed chamber for storing additive. At least one marking conductive component is disposed on the liquid storage box. Any one element or a combination of elements selected from a group consisting of the quantity, position, shape, and resistance of the marking conductive components provided on the liquid storage box indicates correspondingly the type of additive. The identification conductive components are arranged in an accommodating portion of the additive dispensing apparatus. The identification conductive components cover the shadows of the marking conductive components disposed on different liquid storage boxes in the accommodation portion. The marking conductive component of the liquid storage box is spaced from the identification conductive component in the accommodating portion, so as to form capacitance correspondingly indicating the type of the additive.
