Water stopping structure of a spout of a drinking fountain for a pet

摘要

A pet fountain includes a spout projecting from a reservoir, and a tap fastened at one end to the spout and provided at the other end with an opening via which a flow of water is discharged. The tap is provided with a steel ball space in communication with the spout and the opening, and a washer retained in a groove located in proximity of the opening, and a guide edge located between the groove and the steel ball space. A steel ball is movably disposed in the steel ball space such that the steel ball comes in contact with the washer, and such that the steel ball is partially extended out of the opening. The guide edge serves to prevent the steel ball from being inseparably arrested by the washer. The guide edge has a predetermined height which determines the rate of the flow of water discharged via the opening.
