The invention relates to the technical field of water dispensers, in particular to a method and device for preparing drinking
saline water for a water dispenser, a storage medium and the water dispenser. The method comprises the following steps: acquiring salt
elimination influence factors and
exercise duration of a user; calculating the sweating amount of the user in unit time according to the salt
elimination influence factors, and determining a
saline water concentration value according to the sweating amount; determining the
water intake according to the
exercise duration; and controllingthe water dispenser to prepare the drinking
saline water with the
saline water concentration value and the
water volume being the
water drinking amount. By analyzing from two aspects, which are salt
elimination influence factors and motion duration, the loss degree of
moisture and salt ions of the user due to sweating during exercise can be determined, and the water dispenser is further controlledto prepare the drinking
saline water with the concentration of the
saline water concentration value and a volume of the
water drinking amount for the user, the drinking saline water can supplement aproper amount of water for the user and can also supplement salt ions lost in the body of the user due to exercise, and healthy water supplementation of the user is achieved.
