Microfluidic Mixer Chip for Viscosity-Varied Fluid Blending

The patent replaces manual mechanical mixing with an automated microfluidic mixing system that uses electronic controllers, microfluidic chips with integrated channels, and computer-controlled pumps to precisely deliver and mix fluids. This substitution of manual mechanical operations with automated microfluidic systems enables accurate control of microfluidic amounts and ratios while maintaining manageable device complexity through integration.

The microfluidic mixing device is designed as a multi-functional system that can handle multiple fluids with different viscosities, perform mixing, heating, and dispensing operations, and interface with various applications (vaping, aromatherapy, pharmaceuticals). This universal design allows a single device to accomplish multiple tasks that would otherwise require separate equipment, improving precision without proportionally increasing complexity.

The patent integrates multiple functional components (pumps, valves, heaters, sensors, and control systems) into a unified microfluidic device architecture. The microfluidic chip itself combines mixing channels, heating zones, and dispensing mechanisms in a single integrated platform. This merging of functions reduces the overall system complexity compared to having separate devices for each function while maintaining high measurement precision for dispensing microfluidic amounts.

The microfluidic system incorporates self-regulating features such as integrated temperature control within the mixing chip, automated fluid delivery through pressure-driven or electro-osmotic pumps, and feedback-controlled dispensing mechanisms. These self-service capabilities reduce the need for external complex control systems while maintaining precise measurement and dispensing of microfluidic amounts.

The patent employs parameter changes to handle fluids of different viscosities, including adjustable pump speeds, variable heating temperatures to modify fluid viscosity during mixing, and controllable pressure gradients. By dynamically adjusting these parameters, the system maintains accurate control of mixing ratios and flow rates even when combining fluids with widely different viscosities, thus preserving manufacturing precision while achieving application versatility.

The microfluidic chip design incorporates local quality variations with different channel geometries, surface treatments, and heating zones tailored to specific fluid pathways. This allows each fluid stream to be optimized for its specific viscosity characteristics while maintaining precise control over the mixing ratio. The local customization of flow channels and mixing zones enables accurate mixing of multiple fluids with different properties without compromising overall system precision.
