Oral Irrigator Dual-Trigger Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often inadvertently trigger the starting button of oral irrigators before positioning the handle in their mouth, leading to splashing water and a suboptimal cleaning experience.
Innovation Solution
The oral irrigator employs a double starting function with a signal processor and controller system, where a first starting signal is generated when the starter and handle triggers contact, and a second signal is required for the pumping assembly to activate, preventing premature water discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single starting button is provided on the oral irrigator, then the device is simple to operate, but the user may inadvertently trigger water discharge before positioning the handle in the mouth
Solution Approach 1:
The starting function is segmented into two separate triggering mechanisms: a first trigger on the handle and a second trigger on the starting part. Both triggers must be activated simultaneously to initiate water discharge, dividing the single starting action into multiple coordinated actions to prevent accidental activation.
Solution Approach 2:
A controller serves as an intermediary between the two triggers and the pumping assembly. The controller receives signals from both triggers and only activates the pumping assembly when both signals are received, mediating the interaction between the user's actions and the water discharge function.
2Object-affected harmful factors
If a double starting function with signal processor and controller is implemented, then water splashing is prevented, but the device complexity increases
Solution Approach 1:
The mechanical triggering system is enhanced with electronic signal processing. Instead of a purely mechanical switch, the patent uses a signal processor and controller with electrical/electronic trigger mechanisms, replacing simple mechanical operation with a more sophisticated but still user-friendly electronic control system.
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
This configuration effectively prevents splashing water by ensuring the oral irrigator only initiates fluid flow when both starting signals are received, enhancing user experience by ensuring proper readiness before cleaning commences.
Implementation Method 1
the signal processor includes a first radio frequency unit, and the controller includes a second radio frequency unit

AI summary
This disclosure provides an oral irrigator including a base, a reservoir, a handle and a starter. The base has a pumping assembly, a controller and a starting part. The reservoir has a storage cavity and is removably connected to the base and communicates the storage cavity with the pumping assembly. The handle is configured to guide fluid from the pumping assembly. The starter is provided on the handle or removably connected to the handle. One of the handle and the starter has a signal processor, and when the starting part is operated, the signal processor may receive a first starting signal and send it to the controller. The pumping assembly, the controller and the starting part are electrically connected, and when the starting part is operated, the controller receives a second starting signal. The controller controls the pumping assembly to work after receiving the first and second starting signals.
