Solution Overview
Problem
Existing high-capacity electronic atomization devices suffer from poor taste due to unsaturated atomization cores before liquid saturation, and leakage due to excessive liquid absorption leading to condensate flow into central holes.
Innovation Solution
A multi-stage liquid guiding system with liquid guiding elements of varying densities, including a first liquid guiding element with low density for increased storage volume and a second element with high density for rapid absorption, combined with a seal member and vent structure to control liquid transfer speed and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single liquid guiding element is used to wrap around the atomization core, then the device structure is simple, but the liquid supply is unstable causing poor taste and dry hits before saturation and leakage after saturation
Solution Approach 1:
The liquid guiding element is divided into multiple segments with different densities arranged in sequence from bottom to top. The first liquid guiding element has a first density, the second liquid guiding element has a second density greater than the first, and the third liquid guiding element has a third density greater than the second. This segmentation allows different parts of the system to perform different functions: lower-density elements provide liquid storage and gradual release, while higher-density elements provide rapid absorption and transfer to the atomization core, achieving stable liquid supply throughout the entire usage cycle.
2Device complexity
If the liquid guiding element relies solely on capillarity action to continuously absorb liquid, then the absorption mechanism is simple, but the atomization core remains unsaturated before moisturization causing poor taste
Solution Approach 1:
The patent changes the density parameter of the liquid guiding elements to control liquid absorption and transfer rates. By using elements with progressively increasing densities from bottom to top, the system creates different absorption kinetics: lower-density elements absorb liquid more slowly from the storage cavity, while higher-density elements transfer liquid more rapidly to the atomization core. This parameter variation ensures the atomization core receives adequate liquid quantity from the beginning, eliminating dry hits and poor taste.
3Quantity of substance
If the liquid guiding element is completely moisturized, then liquid storage capacity is maximized, but condensed aerosol cannot be absorbed and flows into the central hole causing leakage
Solution Approach 1:
Different sections of the liquid guiding system are assigned different local qualities through varying densities. The lower-density first liquid guiding element in the storage cavity provides gradual liquid release, while the higher-density second and third liquid guiding elements near the atomization core provide rapid absorption and transfer. This local quality differentiation ensures that liquid is consumed at the atomization core as fast as it is supplied, preventing over-saturation and leakage during inhalation while maintaining adequate storage capacity.
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
Stable liquid supply is maintained, preventing leakage and ensuring consistent flavor by controlling liquid transfer speed through the use of elements with different densities and a dynamic vent structure, addressing both early-stage dry hits and late-stage leakage.
Implementation Method 1
The liquid guiding element has a single structure, which relies solely on its capillarity action to continuously absorb liquid until saturation is reached

AI summary
The present application relates to an atomizer and an electronic atomization device. The atomizer includes: a liquid storage cavity; an atomization core; a fixed pipe at least partially arranged in the liquid storage cavity and provided with a liquid inlet hole; and a first liquid guiding element and a second liquid guiding element that are sequentially arranged in the fixed pipe in an axial direction. The first liquid guiding element is in liquid guiding communication with the liquid storage cavity through the liquid inlet hole, and the second liquid guiding element surrounds at least the portion of the atomization core. The density of the first liquid guiding element is less than the density of the second liquid guiding element. The first liquid guiding element has the small density, thereby increasing the liquid storage volume of the first liquid guiding element. The second liquid guiding element has the larger density, thereby accelerating absorption of liquid from the first liquid guiding element and quickly transferring the liquid to the atomization core for atomization. The liquid guiding speed at the contact surface between the first liquid guiding element and the second liquid guiding element may decrease, thereby decreasing the overall liquid guiding speed and avoiding leakage during inhalation due to excessively quick liquid transfer.
