Helical Spray Nozzle Preventing Stream Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprayers experience reduced water swirl and spray range due to interfering streams, jamming from merged components, and alignment issues between the surface cover and water distribution member, which affect spraying efficiency and maintenance.
Innovation Solution
A nozzle design comprising a shell, distributor, panel, and collar with protuberances, tangential passageways, and a sealing ring, where the distributor's fins guide water streams to prevent interference and the panel's outlets ensure efficient atomization, while the collar and annular flange secure components for easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple streams enter each flange to form a whirlpool, then water spray is generated, but the streams interfere with each other reducing water swirl and spray range
Solution Approach 1:
The invention divides the water distribution system into multiple independent distributor elements, each with its own tangential openings and flange. This segmentation prevents stream interference by giving each stream its own dedicated path, eliminating the harmful interaction between multiple streams entering the same flange while maintaining effective water swirl and spray generation.
2Ease of manufacture
If the surface cover is merged with the water distribution member via ultrasonic waves, then assembly is simplified, but the components cannot be disassembled for maintenance and cleaning
Solution Approach 1:
The invention employs a dynamic fastening system using threaded fasteners that allow the surface cover and water distribution member to be easily assembled and disassembled. This replaces permanent ultrasonic welding with a reversible mechanical connection, enabling maintenance and cleaning operations while maintaining manufacturing simplicity.
3Reliability
If the orifices of the surface cover must be aligned with the holes of the water distribution member before connection, then proper water flow is ensured, but the assembly process becomes troublesome and time-consuming
Solution Approach 1:
The invention incorporates pre-aligned features during manufacturing, where the orifices in the surface cover and holes in the water distribution member are pre-positioned to match. Additionally, locating pins or guide features are provided to automatically ensure proper alignment during assembly, eliminating the need for manual alignment operations and reducing assembly time while maintaining reliable water flow paths.

AI summary
A nozzle includes a shell, a distributor, a panel and a collar. The distributor is inserted in the shell. The distributor includes protuberances each of which includes a cylindrical section, a conical section extending from the cylindrical section, and two fins extending from the cylindrical section. The panel includes outlets and tubes. The outlets extend through the panel. Each of the tubes is in communication with a corresponding one of the outlets and includes tangential passageways. Each of the tubes receives a corresponding one of the protuberances. The tangential passageways of each of the tubes receive the fins of the corresponding protuberance so that each of the tangential passageways is partially blocked by the corresponding fin. The collar is connected to the shell and includes an annular flange. The collar receives the panel. The panel is sandwiched between the annular flange of the collar and an end of the shell.
