Solution Overview

Problem

Existing rinsing and brushing integrated oral cleaning devices suffer from interference between drive parts, leading to reduced shock force and inefficient cleaning due to simultaneous operation of vibration and water spraying, which affects rinsing and cleaning effectiveness.

Innovation Solution

An oral cleaning device with a control method that alternately operates the actuator and pump mechanism to perform periodic cleaning motions, ensuring the actuator suspends operation during fluid shock, reducing adverse impacts and enhancing fluid shock force for improved rinsing and cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the actuator and pump mechanism operate synchronously, then both tooth cleaning and tooth gaps rinsing functions are provided, but the vibration of the toothbrush head interferes with water spraying, reducing rinsing effects

Engineering Contradiction:
Improvecleaning functionVSAvoidrinsing effect
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The control component alternates the operation of the actuator and pump mechanism in periodic cycles. During each cycle, the actuator operates first to drive the toothbrush head for cleaning, then the pump mechanism operates to spray water for rinsing tooth gaps. This periodic alternation eliminates interference between the two functions while maintaining both cleaning capabilities.

Inventive Principle:
Principle #19Periodic action

2Duration of action of moving object

If the actuator operates during fluid shock, then continuous cleaning motion is maintained, but energy loss increases and fluid shock force is reduced

Engineering Contradiction:
Improvecleaning motion continuityVSAvoidfluid shock energy
Core Design Contradiction:
Duration of action of moving objectVSLoss of energy

Solution Approach 1:

The system implements periodic operation where the actuator suspends operation during the fluid shock phase. The control component switches between actuator-driven cleaning mode and pump-driven rinsing mode, creating alternating cycles that prevent energy loss from simultaneous operation while maintaining overall cleaning continuity through rapid switching.

Inventive Principle:
Principle #19Periodic action

3Area of stationary object

If the actuator and pump mechanism operate simultaneously, then cleaning coverage is comprehensive, but the shock force is reduced due to interference

Engineering Contradiction:
Improvecleaning coverageVSAvoidfluid shock force
Core Design Contradiction:
Area of stationary objectVSForce

Solution Approach 1:

The control component alternates between actuator operation and pump mechanism operation in sequential phases. During the pump operation phase, the actuator is suspended to eliminate vibration interference, allowing maximum fluid shock force to be applied to tooth gaps. The periodic switching ensures both cleaning functions achieve optimal performance at different times within each cycle.

Inventive Principle:
Principle #19Periodic action

AI summary

The present disclosure relates to the field of oral cleaning device technology, and discloses an oral cleaning device. During operation of the oral cleaning device, an actuator and a pump mechanism are controlled by a control component to alternately operate, so the actuator suspends operation when the pump mechanism is operating. During the operation of the pump mechanism, that is, in a process when tooth gaps are rinsed by means of fluid shock effects of a fluid medium conveyed by the pump mechanism to a fluid cleaning element through a communicating path, a motion cleaning element cannot be driven to perform a displacement motion because the actuator suspends operation, so adverse impacts of the motion cleaning element on the fluid shock effects of the fluid medium are reduced, to improve rinsing effects on the tooth gaps, thereby improving cleaning effects of the oral cleaning device. The present disclosure also discloses a control method for the oral cleaning device, an electronic device, and a storage medium.
