Description

Technical field

Background technique

Most atomization equipments such as electronic cigarettes in the related art use evaporative element parts or heating devices to heat the medium such as e-liquid to change it from liquid to mist state, but the use of these structures will cause chemical reactions of e-cigarette and other media. The production of toxic substances has certain damage to the user's health. With the development of the times, an atomizing device has gradually begun to be used in the field of atomizing equipment. Using the high-frequency vibration of ultrasonic waves, the medium such as e-liquid located next to the ultrasonic device will be used. Ultrasonic atomization is carried out because ultrasonic atomization is a physical process. All e-liquid mediums do not generate toxic and harmful substances, but there are the following problems when using this technology:

1) The unused e-liquid in the atomizing chamber cannot be discharged in time, which may cause residues of e-liquid and other media; causing the e-liquid and other media in the atomizing chamber to deteriorate after a long time, endangering the user's health;

2) The liquid-conducting part wraps the spring to form the atomizing cavity. The atomizing cavity wrapped by the liquid-conducting part has a narrow space, which is likely to affect the atomization effect. At the same time, the liquid-conducting part is prone to stains after a long time. Discharge, even because the suction force is too strong, it will easily cause the medium such as e-liquid or dirt on the liquid guide to be directly sucked out.
