Solution Overview
Problem
Existing electric flushers for personal care, such as ear washers and nose washers, lack a reasonable nozzle flow channel structure that can increase the initial velocity and improve the spray distance and flushing intensity of the water flow.
Innovation Solution
A nozzle assembly comprising a nozzle body with a main flow channel pipe body and a conductor, and a water diversion tip with an installation and flow channel portion and a spherical end portion, which together create a spray separation that allows for directional flow and annular spray of water, enhancing the flushing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only the end of the water outlet pipe is used as a nozzle, then the device complexity is reduced, but the spray distance and flushing intensity are insufficient
Solution Approach 1:
The nozzle is segmented into multiple functional components: a nozzle body with flow channels, a water diversion tip with spherical end portion, and multiple spray separations. This segmentation allows each component to perform its specific function while collectively achieving high-velocity spray without requiring a complex overall structure.
Solution Approach 2:
The invention transitions from a simple linear outlet to a three-dimensional annular spray separation structure. The spherical end portion combined with the radial opening creates an annular geometry that distributes water flow in multiple directions simultaneously, increasing initial velocity and spray distance without proportionally increasing device complexity.
2Manufacturing precision
If a simple water passage nozzle is used, then the manufacturing precision requirements are reduced, but the spray distance and flushing intensity are insufficient
Solution Approach 1:
The nozzle body includes a first flow channel and a second flow channel that pre-condition and direct the water flow before it reaches the spray separation. This preliminary action of shaping and directing flow in controlled channels ensures that water arrives at the spray separation with optimal velocity and direction, maximizing spray distance without requiring extreme manufacturing precision.
Solution Approach 2:
The water diversion tip with its installation and flow channel portion is nested within the nozzle body structure. The spherical end portion fits against the radial opening, creating a compact nested arrangement that achieves complex spray geometry within a small overall footprint, maintaining manufacturing feasibility while achieving long spray distance.
3Ease of manufacture
If the nozzle structure is simplified to reduce device complexity, then the ease of manufacture is improved, but the washing force is insufficient
Solution Approach 1:
The spray separation acts as an intermediary structure between the water outlet and the target surface. By creating an annular separation geometry, it transforms the water flow into multiple high-velocity jets that maintain washing force over distance. This intermediary structure is simple in form (spherical end against radial opening) but effective in function.
Solution Approach 2:
The spherical end portion of the water diversion tip introduces curvature to the flow path, creating smooth transitions that reduce turbulence and energy loss. This spherical geometry naturally directs flow radially outward, generating consistent washing force across the annular spray pattern without requiring complex mechanical adjustments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The nozzle assembly achieves a longer spray distance and a larger washing force due to the increased initial velocity of the annular water column, thereby improving the overall performance of the electric flusher.
