FIELD: liquid atomisation or spraying devices.
SUBSTANCE: group of inventions relates to an aerosol-generating article and a liquid delivery element. Aerosol-generating article contains an aerosol-generating substrate and a mouthpiece attached to the downstream end of the aerosol-generating substrate. Said mouthpiece comprises at least one segment of filter material and fluid delivery element. Fluid delivery element comprises: upstream end and downstream end; a deformable outer container having at least one flexible wall; and brittle tubular element installed inside deformable outer container and forming longitudinal channel, passing through the deformable outer container between the upstream end and the downstream fluid delivery element end. Cavity is formed between at least one flexible wall of the deformable outer container and a brittle tubular element. Cavity contains a liquid that surrounds the fragile tubular element. Fluid delivery element is configured to deliver fluid from cavity to at least one segment of filter material when at least one wall of brittle tubular element is destructed. Fragile tubular element is made with possibility of destruction when force is applied to fluid delivery element for deformation of deformable outer container.
EFFECT: technical result consists in maintaining desired level of resistance to retraction, as well as in minimum change in technology of filter when fluid delivery device is included in filter structure.
