Oral Cleaner Bracket Assembly for Stable Pump Flow Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The poor reliability of connections between water pumps and flow channels in oral cleaners leads to easy detachment, and the design often results in a cumbersome shape that is difficult to clean and reduces the water tank volume.
Innovation Solution
The oral cleaning apparatus rearranges the motor, water pump, and water tank to optimize their distribution, shortening longitudinal lengths and increasing the water tank's volume while enhancing pumping efficiency by using a bracket assembly to stabilize connections and incorporating a microchannel for gas ventilation and leakage prevention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the motor and water pump are arranged independently with separate pipelines, then the pumping function is achieved, but the connection reliability deteriorates due to vibration causing pipelines to detach
Solution Approach 1:
The patent integrates the water pump directly onto the motor's output shaft, merging two previously separate components into a unified assembly. The pump's inlet is directly communicated with the motor's flow channel, eliminating separate pipelines and connection points. This integration ensures that when the motor vibrates, the pump moves with it, preventing detachment and improving connection reliability.
Solution Approach 2:
The water pump is positioned within or around the motor's output shaft area, with the pump's inlet channel directly receiving water from the motor's internal flow channel. This nested arrangement allows the pump to be supported by the motor structure itself, reducing the need for separate mounting pipelines and improving structural stability against vibration.
2Volume of stationary object
If the water tank is enlarged to increase capacity, then the water storage volume is improved, but the overall device shape becomes cumbersome and difficult to clean
Solution Approach 1:
The patent repositions the water tank from a traditional large-volume design to a configuration that utilizes vertical space more efficiently. By arranging the water tank above the motor-pump assembly and using the motor's output shaft as part of the water delivery pathway, the design achieves adequate water capacity without excessive horizontal expansion, maintaining a slimmer overall profile that is easier to clean.
3Reliability
If the motor output shaft is used directly for water flow without integration, then the mechanical driving function is achieved, but the water delivery reliability deteriorates due to lack of integrated flow channel
Solution Approach 1:
The patent combines the motor's mechanical output function with the water delivery function by integrating a flow channel directly into the output shaft. The output shaft simultaneously transmits rotational motion to the brush and delivers water through its internal flow channel to the brush, ensuring reliable water supply without requiring separate piping systems.

AI summary
The oral cleaning apparatus includes a casing, a motor, a pump mechanism, and a bracket assembly. The motor, the pump mechanism and the bracket assembly are all arranged in an inner cavity of the casing. An output shaft of the motor has a first flow channel penetrating through the output shaft, and the bracket assembly is connected to an inner shell wall of the casing. The pump mechanism includes a liquid inlet end, a liquid outlet end, and a power end. The pump mechanism can pump a liquid from the liquid inlet end into a pump chamber of the pump mechanism and pump the liquid out of the liquid outlet end, where the liquid outlet end is integrated into the bracket assembly, and the bracket assembly has a second flow channel communicated with the liquid outlet end and the first flow channel.
