Integrated One-Way Piston Pump for Compact Oral Irrigators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional dental irrigators have bulky designs due to the need for extra space for a liquid-outlet one-way valve, leading to inefficient water usage and inconvenience in carrying or gripping, and they lack sufficient water pressure before and after flow peaks.
Innovation Solution
A compact liquid-outlet system integrates the liquid-outlet one-way valve into the piston of the liquid pump device, eliminating the need for additional space and incorporating a release system for post-peak throttling, enhancing the design for portable dental irrigators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate liquid-outlet one-way valve is installed in traditional dental irrigators, then the liquid-outlet function is achieved, but the device structure becomes bulky and occupies extra space
Solution Approach 1:
The patent merges the liquid-outlet one-way valve directly into the piston structure of the liquid pump device. The piston includes a liquid-outlet valve chamber, valve core, and valve seat integrated within its body, eliminating the need for a separate externally installed valve. This integration maintains the liquid-outlet function while significantly reducing the overall device volume and achieving a compact structure suitable for portable dental irrigators.
2Power
If traditional pump structures are used in dental irrigators, then pumping function is achieved, but the device is inconvenient for carrying or gripping
Solution Approach 1:
The patent integrates the liquid-outlet one-way valve into the piston structure, and combines multiple functions within the liquid pump device including pumping, valve control, and flow regulation. This functional integration reduces the number of separate components, making the overall device more compact and easier to carry or grip while maintaining effective pumping power for dental irrigation.
Solution Approach 2:
The liquid-outlet valve chamber, valve core, and valve seat are nested within the piston body structure. The piston rod extends through the liquid pump cavity in a liquid-tight manner, with the piston dividing the pump chamber into rod chamber and rodless chamber. This nested arrangement maximizes space utilization and creates a compact pump structure that maintains pumping power while improving portability.
3Quantity of substance
If traditional liquid-outlet systems are used, then liquid delivery is achieved, but water pressure is weak before and after flow peaks resulting in inefficient water usage
Solution Approach 1:
The patent incorporates a release system with a release flow channel and post-peak release mechanism that responds to flow conditions in the liquid pump device. The post-peak release mechanism opens the release flow channel only after a flow peak occurs, allowing liquid to be discharged from the rodless chamber through the release flow channel. This feedback-based control optimizes water pressure timing, maintaining effective pressure during critical periods and improving overall water usage efficiency by reducing waste during low-pressure periods.
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 compact design conserves liquid before and after flow peaks, improving convenience and efficiency during oral hygiene procedures, while maintaining effective water pressure and reducing the need for extra space, especially beneficial for small products like portable dental irrigators.
Implementation Method 1
The piston comprises a liquid-outlet one-way valve allowing only liquid to flow from the rod chamber to the rodless chamber
Implementation Method 2
The liquid-outlet valve core abuts the liquid-outlet valve seat when the piston performs an exhaust stroke, and the liquid-outlet valve core is spaced apart from the liquid-outlet valve seat when the piston performs a suction stroke
Implementation Method 3
The liquid-inlet flow channel is communicated with the rod chamber through a liquid-inlet one-way valve
Implementation Method 4
The liquid-inlet one-way valve switches to a closed state... the liquid-inlet one-way valve switches to an open state
Implementation Method 5
The elastic reset member is configured for driving the moving rod to reset
Implementation Method 6
The rodless chamber is in a negative pressure state when the piston performs a suction stroke

AI summary
A compact liquid-outlet system comprising a liquid pump device, a liquid-inlet flow channel, and a liquid-outlet flow channel and an oral cleaning method. The liquid pump device comprises a liquid pump cavity, a piston slidably disposed in the liquid pump cavity, and a piston rod. The piston rod extends through the liquid pump cavity in a liquid-tight manner and is connected to the piston. The piston divides a pump chamber of the liquid pump cavity into a rod chamber and a rodless chamber. The piston comprises a liquid-outlet one-way valve allowing only liquid to flow from the rod chamber to the rodless chamber. The liquid-inlet flow channel communicates with the rod chamber through a liquid-inlet one-way valve. The liquid-outlet flow channel communicates with the rodless chamber. This system eliminates the need of extra space for installing the liquid-outlet one-way valve, resulting in a more compact structure.
