Title: Use of organic porous material in aerosol generating device and atomizer using organic porous material
Inventor: XU YUNSHU
IPC: A24F47/00
Filed: 2020-07-03
Abstract: An application of an organic porous material (2) in an aerosol generating device, and an atomizer using the material. The organic porous material (2) is, at least in part, a melamine resin porous material. The melamine resin porous material has a decomposition temperature exceeding 400°C, can be used for a long time at a high temperature of 180-240°C without any change in properties, and thus can cover the operating temperature range of the atomizer. In addition, the material has a high porosity and controllable pore size distribution, can achieve both good liquid guiding and locking performance, and thus is an ideal liquid guiding material for an atomizer. The organic porous material (2) is applied to an atomizer, and has the advantages of quick liquid absorption, high liquid storage capacity, smooth liquid guide, and outstanding liquid locking capability due to a nano-capillary microstructure formed after liquid infiltration.
