As a popular smoking substitute product, the surface characteristics of the plastic accessories of electronic cigarettes have an important impact on the user experience and maintenance. Among them, surface roughness is a key factor, which is closely related to the residue of smoke oil and the difficulty of cleaning, and it is worth exploring in depth.
Surface roughness refers to the small spacing and tiny peak-to-valley unevenness of the processed surface. For electronic cigarette plastic accessories, the surface roughness depends on the manufacturing process, such as the surface quality of the mold during injection molding, processing parameters, etc. Different roughness values will cause the surface of the accessories to present different microscopic morphologies.
When the electronic cigarette is working, the smoke oil flows on the surface of the plastic accessories. The surface with greater roughness has more microscopic depressions and protrusions, and the smoke oil can easily enter these tiny gaps and grooves and adhere. For example, in the plastic shell of the atomizer core or the inside of the mouthpiece, if the surface is rough, the smoke oil will accumulate in these parts, which will not only affect the normal atomization and transmission of the smoke oil, but also may cause the smoke oil to concentrate locally, changing the taste and smoke output of the electronic cigarette.
The smoke oil residue on the rough surface increases the difficulty of cleaning. Since the smoke oil has a certain viscosity, it is difficult to be easily removed in the microscopic rough structure. Ordinary cleaning methods, such as wiping or simple rinsing, often cannot completely remove the smoke oil remaining in the depression. Moreover, as the number of uses increases, the residual smoke oil will gradually solidify or deteriorate, further increasing the complexity of cleaning, and special cleaning agents or tools may be required for deep cleaning, which increases the user's maintenance cost and time cost.
The material properties of plastic accessories will also interact with the surface roughness to affect the smoke oil residue and cleaning difficulty. Some plastic materials themselves have a certain lipophilicity and are more likely to absorb smoke oil on rough surfaces. For example, some nylon electronic cigarette accessories have a more prominent smoke oil residue problem when the surface roughness is large, and it is easy to absorb smoke oil again after cleaning.
In order to reduce the impact of surface roughness on smoke oil residue and cleaning difficulty, some optimization measures can be adopted. In terms of manufacturing process, improve the processing accuracy and surface finish of the mold, and use precision injection molding technology to obtain a smoother plastic accessory surface. In addition, the surface of plastic accessories can be post-processed, such as polishing and coating, to reduce microscopic defects on the surface, making it difficult for e-liquid to remain and easy to clean.
The surface roughness of electronic cigarette plastic accessories has a significant impact on e-liquid residue and cleaning difficulty. By deeply understanding this influence mechanism and taking corresponding optimization measures, it is possible to effectively reduce e-liquid residue, reduce cleaning difficulty, improve the performance and user experience of electronic cigarettes, and also help to extend the service life of electronic cigarette plastic accessories and ensure the overall quality of electronic cigarette products.
