Rotating Brush Rod Liquid Delivery for Narrow-Neck Bottle Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric cleaning brushes often spray cleaning liquid out of the bottle, especially when cleaning bottles with small openings, and fail to effectively reach the bottom, leading to incomplete cleaning and reduced user experience.
Innovation Solution
An electric cleaning brush design with a rotatable shaft integrated with a liquid delivery channel, featuring a brush rod with liquid outlets, a power device-driven output shaft, and a liquid storage chamber adapter that guides cleaning liquid directly into the bottle while rotating the brush, preventing spray and ensuring thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid outlet is arranged at the front end of the housing and cleaning liquid is sprayed through a conduit, then the cleaning liquid can be delivered to the bottle, but the cleaning liquid sprays out of the bottle especially when cleaning bottles with small openings
Solution Approach 1:
The liquid outlet channel is integrated inside the brush rod, with the liquid outlet positioned at the brush rod end face. This nested structure allows the liquid delivery system to be contained within the rotating brush assembly, enabling direct liquid delivery to the bottle interior without external spraying conduits that cause overflow
Solution Approach 2:
Instead of spraying liquid from the front end of the housing toward the bottle, the liquid outlet is positioned at the end face of the brush rod, delivering liquid directly into the bottle interior through the rotating brush structure. This inverted approach changes the liquid delivery direction from external spraying to internal injection, preventing overflow
2Ease of operation
If the cleaning liquid is sprayed from the top, then the liquid can be delivered to the bottle, but the cleaning liquid concentrates at the top of the bottle and does not reach the bottom directly
Solution Approach 1:
The brush rod rotates during cleaning operation, dynamically distributing the cleaning liquid sprayed from the liquid outlet. This rotation ensures the liquid is dispersed throughout the bottle interior including the bottom area, rather than concentrating at the top, thereby improving cleaning efficiency without requiring additional cleaning time
Solution Approach 2:
The integrated liquid outlet channel ensures continuous liquid delivery to the bottle interior during brush rotation. The liquid is continuously supplied through the rotating brush rod, maintaining constant cleaning action throughout the bottle including hard-to-reach areas like the bottom, eliminating the need for additional cleaning passes

AI summary
The present disclosure provides an electric cleaning brush including a housing, a brush body, a driving component, and an adapter. The brush body includes a brush rod provided with a connected liquid outlet channel and a liquid outlet. The driving component includes a power device and an output shaft, the output shaft is provided with an axial channel, and connected to the power device and the brush rod. The axial channel is connected to the liquid outlet channel. The adapter is fixedly arranged within the housing and has a liquid storage chamber. The output shaft is rotatably connected to the adapter and is provided with lateral channels. The lateral channels are connected to the axial channel and the liquid storage chamber, which is connected to the cleaning bottle. The present disclosure can automatically clean the bottle and the cleaning liquid can be automatically guided out of the brush rod.
