Rotary Control Member for Multi-Stage Water Outflow Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water spray guns require separate operation of two control members for adjusting the amount of water outflow and controlling continuous outflow, which is inefficient and in need of integration for simplified operation.
Innovation Solution
A water spray gun design that integrates two control members into a single control part, utilizing a rotary control member with step-like parts and a press part to adjust the movable valve stem axially, allowing for multi-stage water outflow control through a single operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two control members are used separately for adjusting water outflow amount and controlling continuous outflow, then the control functions are achieved, but the operation complexity increases and efficiency decreases
Solution Approach 1:
The patent combines two separate control members (adjusting nut for outflow amount and positioning member for continuous outflow control) into a single integrated control member that can perform both functions. The control member includes an adjusting portion for axial movement to control outflow amount and a positioning portion for radial movement to control continuous outflow, merging previously separate controls into one unified component that simplifies operation while maintaining full functionality.
2Productivity
If two control members are used separately for adjusting water outflow amount and controlling continuous outflow, then the control functions are achieved, but the time consumption increases
Solution Approach 1:
The patent combines two separate control members (adjusting nut for outflow amount and positioning member for continuous outflow control) into a single integrated control member that can perform both functions. The control member includes an adjusting portion for axial movement to control outflow amount and a positioning portion for radial movement to control continuous outflow, merging previously separate controls into one unified component that simplifies operation while maintaining full functionality.
3Ease of operation
If a single control member is used for both adjusting water outflow amount and controlling continuous outflow, then operation efficiency improves, but the control precision may be compromised
Solution Approach 1:
The control member is segmented into distinct functional portions: an adjusting portion with threaded structure for precise axial movement to control outflow amount, and a positioning portion with positioning holes for precise radial movement to control continuous outflow. The valve stem is also segmented with a valve portion for flow regulation and a positioning portion for location control. This segmentation allows each portion to specialize in its specific control function while being integrated into a single control member.
Solution Approach 2:
The control member enables dynamic control through two independent movement modes: axial movement of the adjusting portion for continuous outflow amount adjustment, and radial movement of the positioning portion for on/off flow control. The valve stem responds dynamically to these movements, with the valve portion adjusting flow based on axial position and the positioning portion controlling flow continuity based on radial position. This dynamic capability allows precise control adaptation within a single integrated component.
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
Enables precise control and adjustment of water outflow with a single operation, achieving multiple stages of water flow by rotating the rotary control member to select different step-like parts, thereby simplifying user operation and enhancing efficiency.
Implementation Method 1
The rotary control member is rotated to select one of the step-like parts corresponding to the positioning part for adjusting the movable valve stem to move forward or backward axially
Implementation Method 2
a press part having one end connected to one end of the movable valve stem. The press part is further provided with a positioning part corresponding to the step-like parts of the rotary control member

AI summary
A water spray gun for control of an outflow of water and adjustment of the amount of the outflow is revealed. The water spray gun includes a handle portion, a pipe portion connected to the handle portion and used for spraying water, and a control device arranged at the position where the pipe portion meets the handle portion. The control device consists of a press part and a rotary control member. The amount of the water outflow is controlled by the rotary control member. The amount of the outflow sprayed out from the pipe portion at respective stages is continuously controlled and regulated by the control device.
