1Manufacturing precision
If a conventional fluid delivery system is used, then the cleaning apparatus can deliver cleaning fluid to the surface, but the fluid distribution is inconsistent and uneven
Solution Approach 1:
The distributor body is segmented into multiple internal reservoirs that are fluidly coupled by channels. This segmentation allows the fluid to be distributed through multiple separate pathways, ensuring consistent and even fluid distribution across all outlets while maintaining a relatively simple overall structure.
Solution Approach 2:
Each outlet in the distributor is provided with a flow restrictor that can be selectively adjusted. This allows local adjustment of fluid flow at each outlet to achieve consistent and even distribution across the entire distributor, addressing specific distribution issues at individual locations without affecting the overall system complexity.
2Productivity
If cleaning fluid is applied to the surface, then cleaning effectiveness improves, but drying time increases
Solution Approach 1:
The flow restrictors allow adjustment of fluid flow parameters at each outlet. By optimizing the flow rate and distribution pattern, the system achieves effective cleaning with reduced excess fluid application, thereby shortening drying time while maintaining cleaning effectiveness.
Solution Approach 2:
The adjustable flow restrictors enable operators to optimize fluid distribution based on observed cleaning performance and drying characteristics. This feedback mechanism allows tuning of the system to achieve the optimal balance between cleaning effectiveness and drying time for different surface types and conditions.

AI summary
A fluid delivery system for a surface cleaning apparatus includes a fluid container configured for storing a fluid, a fluid distributor configured for delivering the fluid to a surface to be cleaned, and a flow controller configured for controlling a flow of the fluid from the fluid container to the fluid distributor. The flow controller includes an adjustable valve and is configured for operating in a first mode of operation that supplies the fluid to the fluid distributor at a first volumetric flow rate; a second mode of operation that supplies the fluid to the fluid distributor at a second volumetric flow rate that is lower than the first volumetric flow rate; and a third mode of operation that supplies the fluid to the fluid distributor at a third volumetric flow rate that is lower than the second volumetric flow rate.
