Aerosol generating product with multilayer groove corrugated structure

Abstract

The invention discloses an aerosol generating product with a multilayer groove corrugated structure. The aerosol generating product comprises an integrated outer tube (1), and an aerosol generating substrate (6), a plugging piece (2), a cavity structure (3) and a filtering piece (4) which are positioned in the outer tube (1), the plugging piece (2) comprises a pipe wall (21) and a pipe cavity (22), the pipe wall (21) is of a groove corrugated structure and comprises an outer layer (211), an inner layer (212) and a groove corrugated layer (213) located between the outer layer (211) and the inner layer (212), the outer surface of the plugging piece (2) is limited by the outer layer (211), and the pipe cavity (22) is limited by the inner layer (212); a plurality of groove corrugated layers (213) are arranged in the pipe cavity (22), and a spacing layer (221) is arranged between every two adjacent groove corrugated layers (213). The plugging piece comprises the multiple groove corrugated layers, the multiple groove corrugated layers support one another, and more airflow channels can be reserved as much as possible on the premise that it is guaranteed that the aerosol generating material is plugged.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn cigarettes, in particular to an aerosol generating product with a multi-layer grooved corrugated structure. Background technique [0002] As consumers pay more attention to health issues and increase their demand for personalized experience of cigarette products, the tobacco industry has continuously responded to the upgrading of consumers' needs and developed various smoking products with reduced scorch and harm reduction. Among them, heated cigarettes can provide a healthier smoking experience while satisfying consumers' sensory requirements for cigarette products because of their different heating methods from traditional cigarette products. [0003] Existing one-piece aerosol-generating articles include an outer tube, an aerosol-generating matrix filled in the outer tube, and other cooling and aerosol-circulating units. At present, the aerosol-generating substrate of the integrated aero...

The problems of the above-mentioned filling preparation method are: 1. When filling, the pipe is placed vertically, and the positions of the sealing parts and filter parts on both sides of the cavity are difficult to locate, and the problem of inconsistent axial lengths of the cavity sections of different samples is likely to occur; 2. The outer surface of the blocking piece and the filter piece and the inner wall of the paper tube are fixed only by friction, and the blocking piece and the filter piece are easily displaced to the cavity section during transportation, or the filter piece is partially sucked out of the outer tube during the suction process; 3. Filling The limited method can only be used for batch filling of individual pipes, and the production efficiency is low

However, the existence of the multi-hole firmware section has brought increased cost and inconvenience to the industrialized manufacture of particle-type aerosol generating products. Therefore, those skilled in the art have always hoped to cancel the multi-hole firmware section.

However, after canceling the multi-hole solid section, an air flow channel section must be set downstream of the particle section to collect and accommodate the aerosol, and this section can also restrain the scattered aerosol source material particles. There is a dilemma, so the design of the plugging piece also needs improvement
