Gardening Sprayer Head With Switchable Central and Peripheral Spray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gardening sprayers can only spray water from the outlet holes around the front end of the sprinkler head, lacking the ability to spray from the center, which limits their effectiveness in large-area irrigation.
Innovation Solution
A gardening sprayer with a main body, switching knob, control member, stopping unit, dividing member, and spraying head, allowing for both central and peripheral water outlets, with a switching mechanism to alternate between these outlets and adjust spray shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water spray gun uses only peripheral outlet holes around the sprinkler head, then the structure is simple, but the irrigation coverage and effectiveness are limited
Solution Approach 1:
The sprinkler head is segmented into multiple independent outlet components: a central outlet and multiple peripheral outlets arranged around the circumference. This segmentation allows water to be distributed through different paths (central and peripheral), significantly expanding the irrigation coverage area while maintaining a relatively simple overall structure.
Solution Approach 2:
The sprinkler head is designed with multi-functionality by incorporating both central and peripheral outlets that can operate simultaneously or independently. This universal design enables the device to adapt to different irrigation needs and cover both near and far areas effectively, enhancing overall productivity without requiring multiple separate devices.
2Adaptability or versatility
If water spray gun adds switching mechanism for central and peripheral outlets, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The switching mechanism employs a movable blocking member that can dynamically shift between different positions to control water flow distribution. This dynamic design allows users to switch between central spray mode, peripheral spray mode, or combined mode by simply moving the blocking member, providing high versatility without requiring complex mechanical structures or multiple components.
Solution Approach 2:
A blocking member serves as an intermediary element between the water supply and the outlets. By positioning this blocking member at different locations within the sprinkler head, users can control whether water flows through the central outlet, peripheral outlets, or both, thereby achieving versatile spray modes with a simple intermediary mechanism rather than complex control systems.

AI summary
A gardening sprayer has a main body, a switching knob, a control member, a stopping unit, a dividing member, and a spraying head. The main body has an entrance portion and an exit portion with an accepting notch; the accepting notch has a through aperture, a first positioning portion, and a second positioning portion at a bottom surface; the through aperture is connected to the entrance portion, a controlling chamber is disposed on a peripheral edge of the exit portion and the exit portion further has a through hole passing the controlling chamber, the spraying head has a plurality of outlet apertures with different shapes at a front end and a spraying aperture at a center position.
