Atomiser Top Cover Air Intake Design for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic cigarettes face liquid leakage issues due to the design of the liquid storage chamber and atomizing assembly, which affects user experience and device operation, and existing leak-proof structures are complex and unreliable.
Innovation Solution
An atomizer design featuring a top cover with an air intake hole and an L-shaped separation member within an inner connecting pipe, partitioning the pipe into an air inlet and smoke outlet passage, allowing external air to enter and carry aerosol formed by atomization, bypassing the separation member to prevent leakage, and a detachable connection for adding liquid from the top side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional leak-proof structures are added to prevent liquid leakage, then liquid leakage is reduced, but device complexity increases and reliability decreases
Solution Approach 1:
The inner connecting pipe is segmented into multiple functional sections: an air inlet section with air inlet holes, a smoke outlet section, and a separation section with a separation member. This segmentation allows air and smoke flows to be separated and guided through different paths, preventing liquid leakage without requiring complex additional leak-proof structures.
Solution Approach 2:
The separation member acts as an intermediary element within the inner connecting pipe, partitioning the pipe interior into an air inlet passage and a smoke outlet passage. This intermediary structure guides the airflow and aerosol separately, preventing liquid from following the air inlet path and leaking out through the smoke outlet.
2Reliability
If the bottom side of the atomizer is sealed to prevent leakage, then liquid leakage is prevented, but air intake for atomization is blocked
Solution Approach 1:
Instead of providing air intake holes in the bottom cover, the invention inverts the air intake location to the top cover. The air inlet holes are formed in the inner connecting pipe of the top cover, allowing air to be drawn from the top side. This inversion maintains a sealed bottom side for leakage prevention while ensuring adequate air supply for atomization through the top-mounted air intake holes.

An atomiser, comprising an upper cover (110), an air intake hole (115) being disposed in said upper cover (110), the upper cover (110) extending inward to form an inner connecting tube (117), a separating member (119) being disposed in the inner connecting tube (117), the separating member (119) separating the inner connecting tube (117) into an air intake channel (1171) and a vapour outlet channel (1173), the air intake hole (115) and the air intake channel (1171) being in communication; and an atomisation assembly (150), an atomisation cavity (163) being formed between the atomisation assembly (150) and the upper cover (110); the gas entering the atomisation cavity (163) via the air intake hole (115) and the air intake channel (1171) carries away the aerosol atomised by means of the atomisation assembly (150), and bypasses the separating member (119) to be released through the vapour outlet channel (1173). Also provided is an aerosol generating apparatus comprising said atomiser.
