Rotating Spray Head and Flow Control for Versatile Handheld Water Sprayers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld water spraying guns typically have a single water outlet mode, limiting their applicability to a specific usage scenario, failing to meet diverse usage requirements.
Innovation Solution
A handheld water sprayer with a handle and spray head that allows for adjustable flow rates and multiple outlet channels, enabling switching between different water outlet modes through a rotatable spray head and a sliding pressing member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single water outlet mode is used, then the device structure is simple, but the adaptability to different usage scenarios is poor
Solution Approach 1:
The spray head is designed to be rotatable relative to the handle, allowing dynamic switching between different outlet channels (first outlet channel for spray mode, second outlet channel for straight shooting mode). This dynamic reconfiguration enables a single device to adapt to multiple usage scenarios without increasing structural complexity
Solution Approach 2:
The device incorporates multiple outlet channels within a single spray head structure, enabling it to perform both spray irrigation and straight shooting functions. The first outlet channel and second outlet channel are integrated into one spray head that can rotate to select different modes, achieving multi-functionality without requiring separate devices
2Ease of operation
If a fixed flow rate is used, then the device structure is simple, but the ease of operation for different tasks is limited
Solution Approach 1:
The pressing member is designed to be slidable along the handle axis, dynamically adjusting the opening degree of the inlet channel. This allows continuous adjustment of water flow rate from small to large, enabling users to optimize water consumption and cleaning efficiency for different tasks without adding complex control mechanisms

AI summary
The present disclosure provides a handheld water sprayer. The handheld water sprayer includes a handle and a spray head. The handle includes a holding body and a pressing member. The holding body defines an inlet channel, and the pressing member is slidably mounted on the holding body and extends into the inlet channel to adjust a flow rate of the inlet channel. The spray head is rotatably mounted on the holding body, and the spray head defines a first outlet channel and a second outlet channel. Rotating the spray head enables at least one of the first outlet channel and the second outlet channel to be communicated to the inlet channel. In this way, a water outlet mode can be switched by rotating the spray head, which is simple to operate. Moreover, the handheld water sprayer can be applied to various scenarios.
