Remote Foam Generator With Two-Stage Mixing for Uniform Bubbles

The mixing process is divided into two distinct stages occurring in separate chambers: the outer mixing chamber performs initial liquid-air mixing, and the inner mixing chamber performs secondary mixing to refine bubble uniformity. This segmentation allows each chamber to optimize its mixing function, achieving both remote dispensing capability and uniform foam quality.

Mix media (such as screens or porous materials) are introduced as intermediary elements between the two mixing chambers. These media facilitate the transition of the liquid-air mixture from the outer chamber to the inner chamber, enabling thorough mixing in the second stage and ensuring uniform bubble distribution in the final foam product.

The mixing system is segmented into two chambers with distinct functions. The outer mixing chamber handles the primary mixing of liquid and air, while the inner mixing chamber refines the mixture to produce uniform bubbles. This segmentation improves foam quality without requiring an overly complex design, as each chamber has a specific optimized function.

The inner mixing chamber is nested within the outer mixing chamber structure. This nested configuration allows the two-stage mixing process to occur within a compact overall form factor, improving foam output quality while controlling device complexity through space-efficient design.

The air inlet is positioned asymmetrically above the liquid inlet, allowing the deflector to effectively direct air flow into the outer mixing chamber. This asymmetric arrangement optimizes the mixing process while the compact chamber design minimizes the vertical space required.

The deflector utilizes angular orientation in the horizontal plane to redirect air flow, rather than requiring additional vertical space. By employing three-dimensional flow management within the existing vertical envelope, the design achieves effective mixing without increasing overall device height.
