Oral Irrigator Pulse Spray Control for Mouthwash Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oral irrigators waste mouthwash due to continuous spraying that may not align with cleaning positions, leading to excessive usage.
Innovation Solution
An oral irrigator with a control method allowing switching between normal and spot spray modes, including pulsed water delivery in the spot spray mode, and manual or automatic operation, using two buttons for mode control and featuring a selection valve to alternate between clean water and mouthwash tanks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the oral irrigator sprays water continuously, then the cleaning coverage is improved, but the mouthwash consumption increases excessively
Solution Approach 1:
The patent implements periodic action by switching from continuous spraying to pulsed spraying mode. The control module enables the water pump to operate in intervals, spraying water for a predetermined time and then pausing, rather than maintaining continuous operation. This periodic operation pattern reduces mouthwash consumption while still achieving effective cleaning coverage at targeted positions.
Solution Approach 2:
The patent applies dynamics by making the spraying operation adjustable and adaptable. The system allows users to switch between normal working mode (continuous spraying) and spot spray working mode (pulsed spraying). This dynamic adjustment enables the device to optimize between cleaning coverage and mouthwash consumption based on specific usage requirements.
2Reliability
If the oral irrigator sprays water continuously, then the cleaning effectiveness is maintained, but the alignment with cleaning positions becomes difficult
Solution Approach 1:
The pulsed spraying operation provides users with time to reposition the spray head between water delivery cycles. This intermittent operation pattern makes it easier to align the spray head with specific cleaning positions while maintaining cleaning effectiveness during the active spray phases.
Solution Approach 2:
The pause intervals in pulsed spraying allow users to perform preliminary positioning actions before the next spray cycle begins. Users can adjust the spray head alignment during these pause periods, ensuring proper positioning before water is delivered again, thereby improving ease of operation.
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 control method reduces mouthwash usage by aligning spray with cleaning positions through pulsed water delivery, maintaining cleaning effectiveness while conserving mouthwash.
Implementation Method 1
The oral irrigator can use a water pump to draw water from the water tank to the nozzle to form a jet stream

AI summary
The present disclosure provides a control method of an oral irrigator and an oral irrigator, wherein the oral irrigator includes a normal working mode and a spot spray working mode. The oral irrigator is capable of switching between the normal working mode and the spot spray working mode. In the normal working mode, the oral irrigator continuously sprays water. In the spot spray working mode, the oral irrigator sprays water in a pulsed manner, with a pause duration between two water sprays.
