Vehicle Electrostatic Atomization Duct with Curved Liquid Traps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle electrostatic atomization systems, the layout restrictions often require the electrostatic atomization device to be positioned lower than the vehicle interior introduction port, leading to the risk of drinking water entering the device through the communication duct, potentially damaging it, especially when the vehicle is on a slope or during layout misalignment.
Innovation Solution
The electrostatic atomization system incorporates a communication duct with a first curved portion downward near the vehicle interior introduction port and a second curved portion upward near the emission port, along with a drain hole in the first curved portion, to prevent backflow of liquids into the device, ensuring that any entering liquid is drained and does not reach the electrostatic atomization device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electrostatic atomization device is arranged in a lower position than the vehicle interior introduction port due to layout restrictions, then the device can be installed in the vehicle, but drinking water may flow into the device through the communication duct causing damage
Solution Approach 1:
The communication duct is designed with curved portions (first and second curved portions) instead of straight connections. The first curved portion curves downward and the second curved portion curves upward, creating U-shaped bends that act as liquid traps. This curvature prevents drinking water from flowing directly from the vehicle interior introduction port to the electrostatic atomization device, while still allowing charged micro-particle water to pass through.
2Adaptability or versatility
If the electrostatic atomization device is positioned lower than the emission port to accommodate vehicle layout, then installation is possible, but the device becomes vulnerable to liquid backflow especially when the vehicle is on a slope
Solution Approach 1:
The curved portions in the communication duct create gravitational barriers that prevent liquid backflow even when the vehicle is on a slope. The downward-curving first curved portion and upward-curving second curved portion work together to trap liquids by gravity, ensuring that drinking water cannot reach the electrostatic atomization device regardless of vehicle orientation or slope conditions.
3Quantity of substance
If the vehicle interior introduction port is used to emit charged micro-particle water directly into the vehicle interior, then the concentration is maintained without dilution, but the port becomes a potential entry point for drinking water
Solution Approach 1:
The communication duct with its curved portions acts as an intermediary between the vehicle interior introduction port and the electrostatic atomization device. It allows the beneficial passage of charged micro-particle water while blocking the harmful entry of drinking water through gravitational liquid trapping mechanisms.
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
This configuration effectively prevents liquids from flowing back into the electrostatic atomization device, protecting it from damage while maintaining the concentration and emission efficiency of charged micro-particle water, ensuring effective deodorization and allergenic substance suppression without dilution by the air conditioner airflow.
Implementation Method 1
an electrostatic atomization device that generates charged micro-particle water by applying a high voltage to a liquid supplied to a discharge unit
Implementation Method 2
The first curved portion is curved downward in a lower position than the vehicle introduction port. The communication duct further includes a second curved portion that is arranged between the first curved portion and the emission port. The second curved portion is curved upward in an upper position than the first curved portion. According to this structure, even if a liquid, such as drinking water, enters the vehicle interior introduction port which emits the charged micro-particle water, a backflow of the liquid to the electrostatic atomization device is suppressed by the first curved portion and the second curved portion.
