Problems solved by technology

However, as a dense metal material, the metal heating sheet also has many problems that limit its further use: First, the graphic size design of the metal heating sheet is limited: the graphic size of the metal heating sheet will affect the resistance value of the heating element and the size of the heating area , in order to ensure the resistance and heating area, the design of the graphic size of the metal heating sheet will be subject to certain restrictions, for example, the use of thin metal heating sheet is conducive to the design of its length and width, but the thinner metal heating sheet has low strength and is prone to deformation , in the process of atomization, the repeated action of the thin metal heating sheet on the temperature will release the internal stress, and it will also cause the heating sheet to warp, resulting in higher defects; and due to the limitation of the technology level and production cost, the width of the metal heating sheet Generally above 0.1mm, so when the metal sheet is thick, the design of its length and width is greatly restricted

Secondly, the bonding strength between the metal heating element and the porous ceramic is poor: the combination of the metal heating element and the porous ceramic substrate is a mechanical fit, and the combination is poor. During the atomization process, due to temperature fluctuations, the metal heating element is prone to loosening or falling off , leading to the weakening of the heat conduction between it and the porous ceramic and the diffusion ability of the atomized liquid to the metal heating sheet, resulting in unstable atomization effect, and in severe cases, it will also produce peculiar smell, which will affect the atomization effect

Again, the utilization rate of the metal heating sheet is low: during the atomization process, the smoke generation area is mainly concentrated in the metal sheet and its surrounding porous ceramic area, and the metal sheet is a dense material. The top will hinder the transmission of the atomized liquid below it to the heating surface, affecting the atomization effect; and only the surface of the metal sheet can contact the atomized liquid to generate smoke, and the utilization rate is low; in addition, during the atomization process, the metal heating sheet The surface will generate a higher temperature. If the e-liquid cannot be transferred to the surface of the metal heating sheet in time, dry burning will occur, which will affect the atomization effect; but because the metal heating sheet has a certain width and is a dense material, the e-liquid will flow to The transmission on the surface of the heating sheet will be more difficult, especially for some e-liquids that have poor wettability with the metal heating sheet
