Water supply structure of drinking water machine

An outlet confluence is arranged between a miniature electric pump and a single outlet, and one or more miniature electric pumps are arranged on the outlet confluence accordingly. The outlet of the miniature electric pump is connected with the inlet of the outlet confluence through a pipeline. The vertical position of the outlet confluence is higher than the internal surface of the drinking water machine, and the outlet confluence is connected with the inlet of the outlet confluence. The outlet of the device is connected to a single outlet of the whole drinking water machine through a pipeline. The outlet diameter of the outlet is larger than that of the intake.

Correspondingly, the diameter of the pipeline connected with the outlet is larger than that of the pipeline connected with the intake. There is also an air outlet on the outlet confluence. The air outlet is connected to the normal temperature water tank through the pipeline, and the outlet is connected to the water confluence. The vent keeps normal pressure in the outlet confluence which is higher than the internal water surface of the drinking water machine, so that the vertical position of the single outlet can be lower than the internal water surface of the drinking water machine, which facilitates the arrangement of the overall structure of the drinking water machine.
