Abstract

An additive dispensing device includes two channels capable of respectively inletting water, a negative pressure water supply channel (500) and a water supply channel (100); a liquid dispensing channel (3) connected to a liquid storage chamber (21) storing an additive; and a control switching structure for changing the connection mode of the liquid dispensing channel (3); the liquid dispensing channel (3) connects the negative pressure water supply channel (500) and the liquid storage chamber (21), and utilizes the negative pressure generated by the inlet water flow of the negative pressure water supply channel (500) to extract the additive in the liquid storage chamber (21) into the liquid dispensing channel (3); or, both ends of the liquid dispensing channel (3) are connected to the water supply channel (100), and part of the inlet water flow of the water supply channel (100) flows into the liquid dispensing channel (3), and the extracted additive is dispensed into the water supply channel (100). Through the above arrangement, the dispensing device can achieve the effect of extracting and mixing the additives in steps by utilizing the inlet water flows of different waterways, and then fully mix the additives by utilizing the inlet water flows that flow into the water supply channel (100) at intervals, thereby greatly improving the mixing uniformity of the additive mixture.
