Rotating Water Dispenser Aerators for Dual Spray Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water discharge devices, such as faucets and bidets, typically offer only single spray functions, either bubbling or needle-like, which do not cater to the varied needs of users for different cleansing tasks, and existing dual-function aerators are complex, large, and difficult to switch between modes, often requiring sealing structures that can lead to jamming issues.
Innovation Solution
A compact aerator with dual spraying functions featuring a rotatable water dispenser and separator, allowing direct fitting into a threaded housing, with needle-like and bubbling water channels that can be switched by rotation, eliminating the need for sealing structures and reducing the number of parts, enabling easy switching between needle-like and bubbling sprays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional aerator is designed with only single spray function (bubbling or needle-like), then the structure is simple and easy to manufacture, but it cannot meet the varied needs of users for different cleansing tasks
Solution Approach 1:
The aerator integrates both needle-like spray and bubbling spray functions into a single device. The water dispenser is designed with multiple water channels (needle-like water channels and bubbling water channels) that can be selectively activated through rotation, allowing one aerator to perform multiple spray functions suitable for different cleansing tasks
Solution Approach 2:
The aerator employs a rotatable water dispenser that can be manually rotated to switch between different spray modes. The rotation of the water dispenser aligns different water channels with the discharge holes, enabling dynamic switching between needle-like spray and bubbling spray functions without requiring complex mechanical mechanisms
2Adaptability or versatility
If a dual-function aerator is designed with both needle-like and bubbling spray functions, then it can meet various user needs, but the structure becomes complex and large in size
Solution Approach 1:
The aerator merges the needle-like water channels and bubbling water channels into a single integrated water dispenser structure. Both types of water channels are arranged concentrically within the same dispenser body, allowing them to be controlled and switched together through a single rotation mechanism, thereby reducing overall structural complexity
Solution Approach 2:
The water dispenser is designed as a rotatable component that can be manually rotated to switch between different spray modes. The rotation of the water dispenser aligns different water channels with the discharge holes, enabling dynamic switching between needle-like spray and bubbling spray functions without requiring complex mechanical mechanisms
3Ease of operation
If a sealing structure is preset between needle-like water passage and surrounding air, then switching between spray modes becomes possible, but the product becomes complicated and large in size
Solution Approach 1:
The aerator employs a rotatable water dispenser that can be manually rotated to switch between different spray modes. The rotation of the water dispenser aligns different water channels with the discharge holes, enabling dynamic switching between needle-like spray and bubbling spray functions without requiring complex mechanical mechanisms
Solution Approach 2:
The invention extracts and eliminates the need for complex sealing structures by using a rotational alignment mechanism. Instead of relying on seals to prevent leakage during mode switching, the design uses the rotation of the water dispenser to naturally align open water channels with discharge holes, simplifying the overall structure
4Adaptability or versatility
If multiple openings are provided for needle-like spray, then switching between spray modes is enabled, but the jetting power is insufficient for applications requiring powerful jetting
Solution Approach 1:
The aerator employs a rotatable water dispenser that can be manually rotated to switch between different spray modes. The rotation of the water dispenser aligns different water channels with the discharge holes, enabling dynamic switching between needle-like spray and bubbling spray functions without requiring complex mechanical 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
The aerator provides a simple, cost-effective solution with extended lifespan, allowing for efficient switching between sprays, maintaining performance under both low and high pressure, and promoting energy saving and environmental conservation.
Implementation Method 1
The flow control assembly comprises a top lid, an elastic body, and a bottom base, wherein the elastic body has a circumference from which at least two pawls extend downward
Implementation Method 2
After the inner core 91 is assembled in the threaded housing 92, there is no obvious projection of the inner core 91 outside the threaded housing 92. The aerator 9 has a water discharge end where only grid-like discharge holes 912 are formed to provide a single type of spray. When water flows through the water separator 911 to fast jet out, a negative pressure is induced around the water discharge openings of the water separator 911 to draw in air through a gap between the threaded housing 92 and the inner core 91 to mix with water for formation of a bubbling spray

AI summary
Disclosed is an aerator with dual spraying functions, including a flow control assembly, a water separator, and a water dispenser that are combined with a housing. The flow control assembly and the water separator are combined together and the water separator and the water dispenser are rotatably connected to each other. The water separator has a surface in which discharge holes are formed. The water dispenser has an internal chamber having a circumferential portion in which needle-like water channels are formed to correspond to the water separator. Bubbling water passages are formed between the needle-like water channels and a central portion surrounded by the needle-like water channels defines a bubbling water channel.
