Solution Overview
Problem
Existing electronic atomization devices face inefficiencies in liquid substrate absorption and aerosol generation, particularly in the design of liquid guide elements and heating mechanisms, leading to suboptimal performance and potential leakage of liquid.
Innovation Solution
The atomizer incorporates a dual liquid guide element system with a first guide element covering the liquid storage cavity opening and a second guide element indirectly absorbing liquid from the first, coupled with a heating element to heat the liquid substrate for aerosol generation, and a holder providing structural support and air flow pathways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single liquid guide element is used to absorb liquid substrate, then the structure is simple, but the liquid absorption efficiency is insufficient and leakage occurs
Solution Approach 1:
The liquid guide element is divided into two separate elements: a first liquid guide element that absorbs liquid from the storage cavity, and a second liquid guide element that indirectly absorbs liquid from the first element. This segmentation improves liquid absorption efficiency and prevents leakage by distributing the absorption function across multiple specialized components.
2Productivity
If direct heating of liquid substrate is applied, then aerosol generation is efficient, but liquid distribution uniformity is poor
Solution Approach 1:
The second liquid guide element acts as an intermediary between the first liquid guide element and the heating element. It indirectly absorbs liquid from the first element and delivers it to the heating element in a controlled manner, ensuring uniform liquid distribution while maintaining efficient aerosol generation.
3Ease of operation
If liquid substrate is directly delivered to heating element, then the atomization process is simple, but liquid delivery control is insufficient
Solution Approach 1:
The liquid delivery path is segmented into two distinct guide elements with different functions. The first element handles bulk liquid absorption from the storage cavity, while the second element provides controlled indirect absorption and delivery to the heating element, improving liquid delivery control.
4Volume of moving object
If a compact atomization assembly is used, then the device size is reduced, but air flow pathways are restricted
Solution Approach 1:
The second liquid guide element is positioned within or adjacent to the first liquid guide element, creating a nested arrangement. This compact configuration reduces overall device volume while the holder provides dedicated air flow pathways that maintain sufficient air flow rate for effective atomization.

AI summary
The present application provides an atomizer and an electronic atomization device. The atomizer comprises: a liquid storage cavity for storing a liquid matrix, the liquid storage cavity being provided with an opening; a first liquid guide element arranged to cover the opening and to absorb and store the liquid matrix from the liquid storage cavity; a second liquid guide element arranged to extend in the longitudinal direction of the atomizer and partially surrounded by the first liquid guide element so as to be located in the first liquid guide element, the second liquid guide element comprising an outer side surface and an inner side surface which are opposite to each other, and the outer side surface being arranged to indirectly absorb the liquid matrix from the first liquid guide element; and a heating element combined with the second liquid guide element and adjacent to the inner side surface, and used for heating at least part of the liquid matrix in the second liquid guide element to generate aerosol. According to the atomizer, the first liquid guide element covers the opening of the liquid storage cavity and absorbs the liquid matrix, and then the second liquid guide element partially located in the first liquid guide element indirectly absorbs the liquid matrix of the liquid storage cavity from the first liquid guide element and then heats and atomizes the liquid matrix to generate aerosol.
