Embodiment Construction

[0064] figure 1 and figure 2 Examples of droplet behavior on hydrophobic and hydrophilic surfaces are shown. The main method used to distinguish a hydrophobic surface 10 from a hydrophilic surface 11 is the contact angle 21 . This refers to the angle 21 formed by a fluid droplet, here an aerosol droplet 2 , at the point of contact with the surface of the rigid substrate 1 . For such as figure 1 For the hydrophobic surface 10 shown, the contact angle 21 is always greater than 90 degrees, and it can be as high as 150 degrees. In the case of contact angles higher than 150 degrees, the surface is said to be superhydrophobic. Such as figure 2 The shown hydrophilic surface 11 has a contact angle of less than 90 degrees and generally less than 50 degrees throughout.

[0065] exist image 3 , examples of combined microstructures and nanostructures are shown. The microstructures 12 are in the form of domes 12, which may be regularly or irregularly arranged on the surface. Th...

Abstract

The electronic aerosol-generating smoking device comprises a main body comprising a heating region for aerosol-forming substrate. At least portions of internal surfaces of the main body in the heatingregion or downstream of the heating region are a hydrophobic or super-hydrophobic surface.

Description

technical field [0001] The present invention relates to electronic aerosol generating smoking devices. Background technique [0002] Various smoking systems are known in which an aerosol-forming substrate is heated in order to vaporize material from the substrate to form an inhalable aerosol. In some systems, the rod of tobacco material is heated by heater blades inserted into the rod. Residue left on the blades and deposits in the flow path can affect the smoking experience. Furthermore, it is often not possible or only extremely laborious to clean parts of the device. [0003] There is a need for aerosol-generating devices to reduce the amount of residue and, in particular, reduce the need to clean parts of the device having an aerosol-forming substrate or components thereof. Contents of the invention [0004] According to the present invention, there is provided an electronic aerosol generating smoking device. The electronic smoking device comprises a body comprisin...
