Multi-channel liquid mixing device

Abstract

This invention provides a multi-channel liquid mixing device, comprising a liquid supply assembly and an electrically connected control module. The liquid supply assembly has multiple liquid storage channels and corresponding drive pumps. The control module has built-in independent compensation parameters for each drive pump and provides dual operating modes to receive mixing commands. In the first mode, the control module parses text information to automatically generate a target ratio configuration; in the second mode, it generates the ratio configuration based on set values. The control module further converts the ratio configuration into a corresponding start-up time based on the independent compensation parameters and precisely controls the sequential operation of the drive pumps. Thus, this invention combines physical electromechanical drive with dual-mode signal processing, significantly improving the accuracy of liquid mixing.
