[0002] The existing water outlet mechanism draws water through the water pump and outputs it along the water outlet component. When the water pump stops running, there will be residual water in the pipeline. So when the water pump runs next time, the residual water will first be output from the water outlet component. In this way, the user will first output the residual water remaining in the pipeline before drinking.
