Venturi Flush Channel for Low-Pressure Closestool Siphoning

The flow increasing device acts as an intermediary component between the injection hole and the drain-off pipeline. It includes a flow increasing channel with a Venturi structure that mediates the water flow, creating a vacuum suction effect that enhances discharge efficiency without requiring high water pressure from the supply source.

The invention utilizes hydraulic principles through the Venturi structure in the flow increasing channel. The constricted section creates a pressure differential that generates vacuum suction, harnessing hydraulic energy to improve flushing performance without increasing supply pressure.

The flow increasing device serves as a mediator that redirects water flow away from direct impact with the bedpan bottom. The flow increasing channel guides water along a controlled path, preventing direct collision with the bedpan surface and thereby eliminating noise and splashing while maintaining flushing effectiveness.

The flow increasing channel is designed to cushion and redirect water flow before it reaches the bedpan bottom. The channel structure pre-conditiones the water flow, distributing it in a controlled manner that prevents sudden impact and the associated harmful effects.

The flow increasing device merges multiple functions into a single integrated component: it combines the injection function, flow amplification through Venturi structure, and noise reduction in one unit. This consolidation simplifies the overall structure and reduces the number of separate parts that need to be manufactured and assembled.

The flow increasing device performs multiple functions simultaneously: it increases water flow velocity, creates vacuum suction for enhanced discharge, and reduces noise and splashing. This multi-functionality reduces the need for separate specialized components, thereby simplifying manufacturing.
