Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facial cleansing devices face issues such as paste leakage, bacterial accumulation, brush deformation, skin damage, and inconvenient brush storage, along with limitations in functionality and design.
Innovation Solution
A cleaning apparatus with a flow regulating mechanism to prevent paste leakage, a dual-brush system for differential rotation, and a lifting mechanism for brush retraction, combined with stimulation elements like LEDs for enhanced skin therapy.

1Ease of operation
If an adjustment ring with baffle is used to control dispensing rate, then the flow rate can be regulated, but the baffle deforms under excessive pressure causing paste leakage and bacterial accumulation
Solution Approach 1:
The adjustment ring is divided into an outer ring and an inner ring that can rotate independently. The outer ring rotates with the bottle cap to control flow rate, while the inner ring remains stationary to prevent paste from entering the adjustment mechanism, thus preventing both leakage and bacterial accumulation.
Solution Approach 2:
A sealing ring is introduced as an intermediary component between the adjustment ring and the bottle cap. This sealing ring prevents paste from leaking into the adjustment mechanism while allowing the adjustment ring to function properly for flow rate control.
2Productivity
If a motor-driven brush disc is used to clean skin, then cleaning effectiveness is improved, but the bristles damage the stratum corneum causing skin harm
Solution Approach 1:
The traditional motor-driven mechanical brush disc is replaced with a sonic vibration mechanism. The sonic brush generates cleaning action through high-frequency vibrations rather than mechanical rotation and pressure, effectively cleaning skin while avoiding damage to the stratum corneum.
Solution Approach 2:
The cleaning mechanism changes from mechanical motion (rotation and pressure) to vibrational motion (sonic frequency). This parameter change allows the brush to clean effectively through vibrations while applying minimal mechanical stress to the skin, preventing damage to the stratum corneum.
3Ease of operation
If the brush is protruding from the bottle, then it is accessible for use, but it requires a separate cover for protection and storage
Solution Approach 1:
The brush assembly is merged with the bottle structure, with the brush rotating on the bottle cap itself. This integration eliminates the need for a separate cover, as the brush is protected by the bottle cap when not in use and remains accessible when needed.
Solution Approach 2:
The bottle cap serves multiple functions: it seals the bottle, protects the brush when not in use, and provides the mounting structure for the brush rotation mechanism. This multi-functionality eliminates the need for separate protective covers and simplifies storage.

AI summary
Embodiments of the present invention provide a cleaning apparatus for cleansing the skin. The apparatus comprises a brush assembly rotably installed in a housing. The brush assembly is driven by a driving assembly to rotate in circular manner to cleanse the skin. The brush assembly may further comprise a lifting assembly for driving the brush assembly to stretch out or retract into the housing, such that when it is necessary to use the cleaning device, the brush assembly can be controlled to extend out of the housing. During idle state, the brush assembly can be controlled to enter the housing through the lifting assembly, so as to prevent the brush assembly from being exposed, damaged or contaminated to a certain extent, so as to facilitate the storage and carrying of the cleaning device.
