The first preset gap is set to ensure that the impeller 3 can drive the stirring part 2 to rotate under normal conditions. After a period of time, the additive 4 is accumulated and blocked in the first preset gap, the impeller 3 can drive the casing 1 to rotate integrally, and the additive can be released into the pipeline 100 through the release hole 11 under the action of centrifugal force.

Stirring member 2 sets up in casing 1, and one end can stretch out casing 1 and impeller 3 fixed, and impeller 3 rotates and drives stirring member 2 and rotate under the impact of fluid, stirs the mixture of the fluid in casing 1 and additive 4. The diameter of the discharge hole 11 is set to have a different diameter according to the additive in the housing 1, so that it is ensured that the additive does not flow into the duct 100 through the discharge hole 11 or only a small portion of the additive can flow into the duct 100 when the fluid in the duct 100 is stationary.

Optionally, the duct 100 comprises a fluid inlet 101 and a fluid outlet 102, the fluid inlet 101 and the fluid outlet 102 are respectively disposed at two ends of the duct 100, and an axis of the fluid inlet 101 and an axis of the fluid outlet 102 are both coincident with an axis of the duct 100.

When the water purifier is used, water in the pipeline 100 flows, the impeller 3 rotates under the impact action of the flowing water to drive the stirring piece 2 or the shell 1 to rotate, so that the scale inhibitor is released into the pipeline 100 under the action of centrifugal force, and the larger the flow rate of the water is, the larger the release amount of the scale inhibitor is, so as to meet the requirement of purifying the used water.

When there is a specific need for drinking water, such as the need for added minerals and probiotics, the user needs to drink the water. The additive 4 in the slow release device in the water dispenser is mineral matter and/or probiotics.
