Electronic atomization equipment specifically includes medical liquid atomization equipment.

In the existing atomizing core, one of the materials used as the liquid-conducting body is generally a long glass fiber rope or cotton rope, and the heating wire for heating is directly wound on the glass fiber rope or cotton rope. The performance is poor. During the heating process, it is easy to burn due to the small amount of liquid storage and the untimely conduction of the atomized liquid, resulting in a burnt smell, resulting in poor user experience. Another atomizing core made of ceramics does not have an atomizing cavity on its body, so the area of the atomizing surface is small, and the vapor or aerosol formed after the atomizing liquid is heated and evaporated is carried out by the airflow. The speed is slow, the atomization efficiency is low, or there is no atomization chamber set horizontally, and the atomization liquid in the vertical atomization chamber is easily concentrated at the bottom end, so the atomization is uneven and the atomization is not sufficient, which also affects the atomization. Efficiency and fog output.
