Liquid Diffuser With Integrated Nozzle Plate

The patent merges the nozzle-holding plate with the diffuser body by forming the plate as an integral part of the diffuser housing. This integration eliminates the need for separate external plates and their associated mounting hardware, thereby reducing assembly complexity while maintaining nozzle interchangeability through the integrated plate's nozzle seats and retaining structures.

By forming the nozzle-holding plate as an integral part of the diffuser housing, the patent eliminates the risk of losing the plate. The integrated plate cannot be separated from the housing, ensuring that the plate and its nozzle-retaining features remain permanently attached to the diffuser body while still allowing nozzle removal and replacement.

The patent segments the nozzle retention function into two distinct mechanisms: a snap-fit connection for quick initial attachment and a threaded locking mechanism for secure long-term retention. The nozzle first engages the snap-fit seat for rapid installation, then the threaded lock is engaged to prevent deformation and maintain connection efficiency over repeated use, while still allowing relatively easy removal by undoing the thread.

The patent incorporates identification features on the nozzles and/or holding plate that enable visual distinction between different nozzle types. These may include color-coded rings, painted sections, or contrast-colored identification elements that allow users to quickly identify nozzle characteristics such as spray pattern or flow rate without having to handle or test each nozzle.
