AI Technical Summary

Technical Problem

The existing liquid injection structure results in a limited range of compatibility for e-cigarette cartridges, making it impossible to simultaneously accommodate different types of e-liquid bottles and ensure a tight seal.

Method used

A liquid injection structure was designed, including a cartridge, a guide channel, and a moving component. The guide channel and the injection hole work together to achieve rapid blocking and flow, support the connection of various oil bottle models, and ensure sealing through the interference fit of the elastic element and the blocking element.

Benefits of technology

It enables rapid opening and sealing of the liquid injection structure, expands the compatibility range of e-cigarette cartridges, improves liquid injection efficiency and sealing performance, avoids leakage and blockage of aerosol media, and extends service life.

Abstract

The application belongs to the technical field of aerosol generating devices, and relates to a liquid injection structure and an aerosol generating device. The liquid injection structure comprises: a cartridge, which is provided with a liquid storage cavity, a guide channel and a liquid injection hole. The liquid injection hole and the guide channel are oppositely arranged. The guide channel is connected with an external environment and the liquid storage cavity. The liquid injection hole is connected with the external environment and the liquid storage cavity. A moving assembly is movably arranged in the guide channel and is in interference fit with the guide channel. The moving assembly is used for reciprocating movement along the guide channel and blocks the liquid injection hole and the guide channel. The liquid injection structure can move along the guide channel, thereby quickly blocking and conducting the liquid injection hole. In the mode of supplementing aerosol generating medium by using a liquid injector, the liquid storage cavity can be quickly opened or sealed. In addition, an oil bottle can be connected to the cartridge through the liquid injection hole, thereby matching the cartridge. Therefore, the liquid injection structure has a wide range of adaptation.
