Description

Technical Field

[0001] This utility model relates to the field of sparkling water machine technology, and in particular to a two-in-one control valve for a sparkling water machine and a sparkling water machine. Background Technology

[0002] In existing sparkling water machine designs, controlling the on / off flow of water and gas, as well as wastewater discharge, typically relies on the coordinated operation of multiple independent valve assemblies (most commonly two solenoid valves). One solenoid valve controls the inflow of water from the tank into the mixing chamber (stirring chamber), while the other controls the output of the finished sparkling water from the mixing chamber and the discharge of waste liquid (such as rinsing water or residual liquid). This dual-valve or multi-valve system requires the installation of multiple independent valves, corresponding drive circuits, and connecting pipelines, increasing the internal structural complexity and overall size of the equipment. This hinders miniaturization and compact design, as the timing and status of multiple valves need to be coordinated, making the control program relatively complex.

[0003] To address this issue, this utility model proposes a two-in-one control valve for a sparkling water machine and a sparkling water machine in general, thus providing a solution. Utility Model Content
