Spray Gun Shower Head Automatic Reset Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray gun shower heads do not effectively prevent damage or injury caused by high-pressure spray gun water when switched back to normal mode, as they often inadvertently spray high-pressure water, leading to accidents.
Innovation Solution
A spray gun shower head with an automatic reset function, featuring a switching body that rotates between two positions, a reset assembly, and a hydraulic positioning assembly, which automatically covers the high-pressure water outflow path after use, ensuring safe switching back to normal mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the shower head is inserted into the shower holder after using spray gun water, then the shower head can be stored conveniently, but the shower head may inadvertently spray high-pressure water again when used, causing damage or injury
Solution Approach 1:
The patent applies preliminary action by automatically resetting the switching body to the first switch position (normal water mode) when the shower head is placed in the holder. This pre-action ensures that before the shower head is used again, it is already in a safe state, preventing inadvertent high-pressure water spraying and potential injury.
Solution Approach 2:
The patent implements feedback through the reset assembly that detects when the shower head is inserted into the holder and automatically triggers the switching body to return to the safe position. This feedback mechanism ensures the system self-corrects to prevent harmful effects, resolving the contradiction between storage convenience and safety.
2Productivity
If the shower head sprays spray gun water in high-pressure state, then cleaning effectiveness is improved, but objects or human body in the bathroom may be impacted, causing damage or injury
Solution Approach 1:
The patent applies dynamics by making the switching body rotatable between different positions (first switch position for normal water mode and second switch position for spray gun water mode). This dynamic switching mechanism allows users to select the appropriate mode based on needs, enabling high-pressure spray for effective cleaning while preventing accidental activation that could cause injury.
Solution Approach 2:
The patent introduces an intermediary element - the switching body - that mediates between the water supply and the outflow paths. This intermediary controls water flow direction, allowing high-pressure spray when needed while preventing inadvertent activation, thus resolving the contradiction between cleaning effectiveness and safety.
3Object-affected harmful factors
If the second water outflow path is hidden in the shower body through a cover, then protective effect and usage prompt effect are improved, but the structure becomes more complex
Solution Approach 1:
The patent merges the cover function with the switching mechanism. The cover is linked to the switching body position, automatically opening when the switching body is in the second switch position (spray gun mode) and closing when in the first switch position (normal mode). This integration provides protective effect while minimizing additional structural complexity.
Solution Approach 2:
The cover is pre-positioned to cover the second water outflow path, providing automatic protection. When the switching body moves to the spray gun mode, the cover automatically opens in advance, ensuring safety while maintaining a simple integrated structure rather than adding separate complex mechanisms.
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
Prevents accidental high-pressure spraying, enhancing user safety and experience by automatically resetting to normal mode, with a hidden and protected water outflow opening that promotes safe usage and stability.
Implementation Method 1
The reset member is disposed on the shower body, and one end of the reset member cooperates with the push block
Implementation Method 2
The shower body has a water intake path and at least one first water outflow path and at least one second water outflow path

AI summary
A spray gun shower head includes a shower body, a switching body and a reset assembly. The shower body has a water intake path and at least one first and second water outflow paths. The switching body is movable between first and second switch positions and configured to switch the water intake path to be communicated with the first or second water outflow path. The reset assembly includes at least one reset member and a push block. The second water outflow path is hidden in the shower body through a cover. The cover is pushed against by an opening structure to be opened. The reset member is disposed on the shower body, and one end thereof cooperates with the push block. The push block is disposed on the switching body and rotates toward the second switch position along with the switching body to press against the reset member.
