Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steam brushes suffer from inefficient heat utilization, limited angle of use, and water accumulation leading to dripping and insufficient steam ejection due to single-layer or poorly designed double-layer heating structures.
Innovation Solution
A double-layer electric heating plate with multiple channel units and staggered through openings between layers, allowing for efficient heating and steam production across various angles, featuring a U-shaped heater and temperature sensor for control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-layer flow channel is used in the electric heating plate, then the structure is simple, but the heat utilization is inefficient and the steam brush can only be used horizontally
Solution Approach 1:
The heating plate is divided into two independent heating layers, each with its own flow channels. This segmentation allows water to be distributed across multiple heating zones simultaneously, improving heat utilization efficiency while maintaining structural simplicity through modular design
2Device complexity
If a single-layer flow channel is used in the electric heating plate, then the structure is simple, but the steam brush has limited angle of use and drips when tilted
Solution Approach 1:
The design transitions from a single-layer to a double-layer structure, adding a vertical dimension to water distribution. This allows water to be heated simultaneously in multiple layers, enabling the steam brush to maintain effective steam generation at various angles without dripping
3Adaptability or versatility
If a double-layer heating structure with single channel per layer is used, then the steam brush can be used at any angle, but water accumulates at lower position and the first layer fills with water taking long time
Solution Approach 1:
Each heating layer is divided into multiple flow channels, segmenting the water flow path. This segmentation prevents water accumulation in any single channel, reduces filling time by providing multiple parallel flow paths, and maintains adaptability for use at various angles through balanced water distribution
4Adaptability or versatility
If a double-layer heating structure with single channel per layer is used, then the steam brush can be used at any angle, but the second layer is short of water and steam ejection is insufficient
Solution Approach 1:
The water flow system is segmented into multiple channels across two layers, with communication between layers through through-openings. This segmentation ensures water is distributed to both layers simultaneously through multiple paths, preventing water shortage in the second layer while maintaining angle adaptability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures continuous steam output and prevents dripping by quickly redistributing water across multiple channels, ensuring thorough heating and uniform steam distribution regardless of brush angle.
Implementation Method 1
heat generated by the electric heating tube
Implementation Method 2
water from the water inlet is directly ejected out of steam holes of the electric heating plate after being vaporized
Implementation Method 3
water in the channel units is heated until it is vaporized into high-temperature steam

AI summary
The disclosure provides a double-layer electric heating plate and a steam brush. The double-layer electric heating plate has a first heating layer and a second heating layer facing away from each other. The first heating layer and the second heating layer are respectively provided with at least two channel units. The channel units of the first heating layer and the channel units of the second heating layer are in communication with each other end to end in a staggered manner through a plurality of through openings to obtain heating channels running back and forth between the first heating layer and the second heating layer, which can effectively prevent the steam brush from dripping when used at all angles.
