Water-Changing Brush Washer With Segmented Fluid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush washers suffer from turbid water when changing the water, and the water storage tank volume is either insufficient or inconvenient for transportation due to size constraints.
Innovation Solution
A water-changing brush washer with a sealed water storage tank, a button structure, and a base, featuring a wastewater outlet connected to a dirty water pool, and a mechanism using a power arm, resistance arm, and pool plug to control water flow, ensuring clean water remains separate from dirty water during the washing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the water storage tank volume is increased to prevent clean water and dirty water mixing, then water capacity is improved, but transportation convenience deteriorates
Solution Approach 1:
The brush washer is divided into separate functional modules: a water storage tank for clean water, a brush washing pool for washing brushes, and a dirty water pool for collecting used water. This segmentation allows each component to be optimized independently - the water storage tank can be made compact for transport while still providing sufficient water capacity through efficient design.
Solution Approach 2:
The water storage tank is designed to be nested within or attached to the brush washing pool structure. The tank can be positioned such that it integrates with the base structure, allowing the clean water storage function to be incorporated into the existing device footprint without requiring a separate, bulky container that would compromise transportation convenience.
2Reliability
If a button mechanism is added to control water flow and prevent mixing, then water separation reliability is improved, but device complexity increases
Solution Approach 1:
A button mechanism serves as an intermediary control element between the user and the water flow system. When the button is pressed, it simultaneously activates two functions: opening the wastewater outlet to drain dirty water and closing the water flow channel to prevent clean water from mixing with dirty water. This single intermediary component achieves reliable water separation through coordinated control of multiple flow paths.
Solution Approach 2:
The button mechanism merges multiple control functions into a single action. Pressing the button combines the operation of opening the wastewater outlet and closing the water flow channel into one simultaneous event. This consolidation ensures that clean water is prevented from mixing with dirty water while maintaining simple user operation, achieving reliable separation without requiring multiple separate controls.

AI summary
This utility model discloses a water-changing brush washer, which includes a sealed water storage tank, a button structure, and a base; one side of the base forms a brush washing pool, the bottom of the base forms a dirty water pool, the bottom of the brush washing pool is equipped with a wastewater outlet, and the button structure includes a water-changing button, a reset spring, a power arm, a resistance arm, and a pool plug. One end of the power arm is connected to the water-changing button, and the other end is connected to the pool plug; one end of the resistance arm is connected to the outer side of the bottom of the brush washing pool, and the other end is connected to the pool plug; the bottom of the water storage tank is equipped with a water outlet, another side of the base is equipped with a water inlet, and the base has a water flow channel connecting the water inlet and the brush washing pool. The water flow channel is equipped with a water-changing button installation hole, and one side of the bottom of the water-changing button is equipped with a baffle. The water-changing button is movably installed in the installation hole. The advantage is that when the water-changing button is pressed, the baffle will block the fresh water in the water flow channel, and after the dirty water in the brush washing pool is drained, when the water-changing button is released, the fresh water flows into the brush washing pool.
