AI Technical Summary

Technical Problem

The central rod oil cup structure of existing small-volume atomizing devices makes liquid addition difficult and results in a poor user experience, mainly due to the small liquid addition space and capillary action, which makes it difficult for the liquid to flow freely.

Method used

Design an atomizing core with the atomizing chamber offset to the circumferential side for guiding the liquid, the heating element attached to the inner wall of the atomizing chamber, and the air guide tube located on the side of the shell. The liquid storage chamber has a large volume, the air guide channel is smooth, and there are fewer components, which facilitates automated assembly.

Benefits of technology

The increased volume of the liquid storage chamber facilitates the addition of the aerosol generation matrix, reduces material costs, and enhances user experience and product competitiveness.

Abstract

This utility model discloses an atomizing core, an atomizing device, and an aerosol generating apparatus. The atomizing device includes an atomizing core comprising a liquid guide and a heating element. The liquid guide has an atomizing chamber for communicating with an air guide channel in the outer casing. The atomizing chamber is offset towards a first circumferential side of the liquid guide, or the atomizing chamber has a portion of its structure penetrating the first circumferential side of the liquid guide, making the atomizing chamber more offset towards the side wall of the outer casing, thus improving the communication between the atomizing chamber and the air guide channel. The air guide tube of this atomizing device is formed on the side of the casing. Compared to a central rod oil cup structure, the air guide tube occupies less internal space in the casing, increasing the volume of the liquid storage chamber. Furthermore, due to the larger volume of the liquid storage chamber, the aerosol generating matrix can be added from the liquid storage chamber, making addition more convenient. Moreover, this atomizing device has fewer components, which facilitates automated assembly, reduces material costs, and improves product competitiveness.
