US Patent 11529599 Electromechanical valve sequencing for fluid mixture dispensing devices

Systems and methods for reducing the overall current draw of a fluid mixture dispensing device are disclosed. A disclosed system includes a mixing area, a set of ingredient reservoirs, and a set of electromechanical valves. The set of electromechanical valves are in a one-to-one correspondence with the set of ingredient reservoirs, and fluidly connect the set of ingredient reservoirs and the mixing area during a respective set of dispense times. The system further includes a controller programmed to actuate at least two valves from the set of electromechanical valves to dispense, to the mixing area, at least two ingredients from the ingredient reservoirs associated with the at least two valves. The controller is programmed to actuate the at least two valves in sequence with partially overlapping dispense times and without overlapping opening times.
