AI Technical Summary

Technical Problem

Existing e-cigarettes are prone to leakage in environments with high altitude and low pressure, high temperature and high humidity, and long-term static storage, which affects the user experience and poses safety hazards.

Method used

Design a closed atomizer with a structure of oil cup, atomizing component, component support and oil cup base. Through the mechanical contact between the outer end of the atomizing component and the first annular step, the interference fit between the first sealing ring and the inner wall of the oil cup, and the interference fit between the second sealing ring and the inner wall of the bottom of the oil cup, a full-range seal is formed to prevent e-liquid leakage.

Benefits of technology

It effectively prevents e-liquid from leaking out under high pressure, high temperature or vibration, improving the user experience and eliminating safety hazards.

Abstract

This utility model relates to the field of atomizer technology and discloses a closed atomizer with good oil-locking effect and condensation recovery capability. It includes an oil cup (102) for holding e-liquid, atomizing components (104-107), a component support (103), and an oil cup base (101). A first annular step is provided in the middle section of the inner side of the component support (103), and the outer end of the atomizing components (104-107) abuts against the first annular step. A first annular groove is provided in the middle section of the outer side of the component support (103), and a first sealing ring is installed in the first annular groove. The first sealing ring is press-fitted with the inner wall of the oil cup (102). A second annular groove is provided in the middle section of the outer side of the oil cup base (101), and a second sealing ring is installed in the second annular groove. The second sealing ring is press-fitted with the inner wall of the bottom of the oil cup.
