AI Technical Summary

Technical Problem

Existing electronic cigarettes face challenges in miniaturization due to internal component constraints, leading to increased inhaling resistance and poor user experience, as well as discomfort during gripping and carrying due to their thickness.

Method used

The atomization device features a shell with a ventilation hole and atomizing core assembly staggered in the width direction, allowing for a more compact design that minimizes the shell's thickness while maintaining functionality, and includes a one-way ventilation seal to prevent liquid leakage.

Benefits of technology

This design enhances user experience by reducing inhaling resistance, accommodating more e-liquid, and providing a thinner, more ergonomic device that meets the requirements for miniaturization without compromising performance.

Abstract

Provided are an atomization device for an electronic cigarette, and an electronic cigarette. The atomization device for an electronic cigarette comprises a housing (1) and an atomization core assembly (3). The housing (1) has a length direction, a width direction and a thickness direction, and is provided with an air outlet (111). A liquid storage cavity (100), an atomization cavity (200) and a separator (2) are provided in the housing (1). The liquid storage cavity (100) and the atomization cavity (200) are located on the two sides of the separator (2) along the length direction of the housing (1). A vent hole (4) passing through the length direction is formed at the separator (2). The atomization core assembly (3) is fixed on the separator (2), and is staggered from the vent hole (4) along the width direction. An air outlet pipeline (5) is provided in the housing (1), and communicates the air outlet (111) with the vent hole (4); and the atomization cavity (200) is communicated with the air outlet pipeline (5) by means of the vent hole (4). The atomization core assembly (3) is configured to absorb a liquid in the liquid storage cavity (100) and atomize the liquid.
