Pulsation Disc Shower Head for Strong Jets at Low Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shower heads often fail to produce fully developed jets at low liquid pressure.
Innovation Solution
A sanitary shower head design featuring a pulsator chamber, pulsator disc, and supply channels that utilize fluid flow energy to alternately open and close chamber inlets, generating strong jets even at low pressure through a pulsator disc's wobbling motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a conventional shower head is used, then the structure is simple, but the spray pattern is weak at low liquid pressure
Solution Approach 1:
The shower head employs a pulsator disc that dynamically alternates between open and closed positions to create pulsating flow. This dynamic mechanism allows the system to generate strong jets even at low inlet pressure by concentrating flow through alternating chamber closure, resolving the contradiction between maintaining simplicity and achieving effective spray at low pressure.
Solution Approach 2:
The pulsator disc creates periodic opening and closing of chamber inlets, generating alternating flow pulses. This periodic action transforms continuous low-pressure flow into concentrated jet bursts, enabling strong spray patterns without requiring high continuous pressure or complex multi-component structures.
2Productivity
If liquid pressure is low, then energy consumption is reduced, but jet development is insufficient
Solution Approach 1:
The shower head divides the flow into multiple chambers (first chamber, second chamber, etc.) with individual inlet openings. The pulsator disc sequentially closes these chamber inlets, segmenting the continuous flow into discrete pulses. This segmentation allows each chamber to build pressure and deliver concentrated jets even when overall inlet pressure is low, improving jet development without requiring high pressure.
Solution Approach 2:
The system changes the flow parameters dynamically by alternating between open and closed states of chamber inlets. This parameter change transforms low continuous pressure into high instantaneous pressure pulses during the closed phase, enabling strong jet development while operating from low inlet pressure sources.

Function Achieved in This Case
Ensures strong liquid jets are generated even at low liquid pressure by alternately opening and closing chamber inlets with a pulsator disc, enhancing jet development.
Implementation Method 1
The movement of the pulsator disc is achieved exclusively by the flow energy of the fluid entering the pulsator chamber
