Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a water outlet structure and drinking water equipment. Background Technology

[0002] Currently, as people's quality of life continues to improve, their pursuit of coffee brewing methods and taste is also increasing. Hand-drip coffee, with its unique brewing process and rich taste experience, is favored by many coffee lovers.

[0003] However, traditional water dispensers only allow water to flow from a fixed position, failing to achieve the movement and variation of water flow seen in pour-over coffee. This results in uneven extraction of coffee grounds, affecting the coffee's taste. Existing technologies, such as the Chinese patent CN206534539U, have considered using mechanical transmission to change the water outlet position. This involves a motor rotating the spout, causing the two outlets to rotate together. However, this can easily create an extraction "dead zone" between the two outlets, resulting in a less than ideal pour-over simulation. Utility Model Content
