Description

The present invention relates to the technical field of manufacturing non-combustion / low-temperature heating type smoking articles, and specifically to aerosol-generating articles containing a support blocking member.

Non-combustion / low-temperature heating type smoking articles are attracting the attention of many cigarette makers because they have advantages such as significantly reducing harmful substances in the smoke by non-combustion / low-temperature heating and less passive smoking.

Conventional non-combustion / low temperature heating type smoking articles mainly include an aerosol generating member having a pellet-shaped, chopped tobacco or sheet-shaped and paste-shaped smoking material, a support blocking unit, and a filter member. The support blocking unit adjacent to the aerosol generating member 1. supports the outer tube of the non-combustion / low temperature heating type smoking article; 2. The fuming particles or fuming paste of the aerosol generating member are blocked, and the fuming particles to the filter member. Alternatively, it must prevent the movement of the fuming paste; 3. It must have a support blocking function and an airflow passage for guiding the aerosol generated from the aerosol generating member 2 to reach the filter member 4 through the supporting blocking member 3. Instead, it serves the purpose of lowering the temperature as the aerosol flows through the air passage and reaches the smoker's oral cavity. The conventional support blocking unit has 1. in order to improve the support blocking performance, its airflow passage becomes small and the aerosol passage rate becomes low; 2. the cross-sectional shape of the support blocking member is complicated, so that the manufacturing process is complicated.

It may be arranged in a row, another functional member may be inserted between adjacent two, or a predetermined interval may be provided. The other functional member may be a temperature lowering and incense increasing member having a temperature lowering and incense increasing material.

A circumferential airflow passage 5 in the longitudinal direction is formed between the outer edge of the support blocking member 3 and the inner edge of the pipe body 1. An object of the peripheral airflow passage 5 is to guide the aerosol generated from the aerosol generating member 2 to reach the filter member 4 through the support blocking member 3 and further to reach the smoker's oral cavity.

Preferably, the inside of the support blocking member 3 further has a longitudinal central airflow passage 6 penetrating the support blocking member 3 along the axial direction. The central airflow passage 6 can increase the passage area of the aerosol, the purpose of which is to allow the aerosol generated from the aerosol generating member 2 to reach the filter member 4 through the support blocking member 3 and further reach the smoker's oral cavity. It also includes inducing.

Preferably, the cross section of the central airflow passage 6 is circular, polygonal, star-shaped polygonal, alphabetical or numeric. Of these, circular or polygonal shapes are often used.

These are merely examples, but may be any shape that forms a hollow portion, forms a central airflow passage, and allows the aerosol to pass through.

Preferably, chamfers 7 are provided at both ends of the support blocking member 3. The chamfer 7 is formed so as to be inclined from both ends of the support blocking member 3 toward the central portion of the support blocking member 3, so that the support blocking member 3 can easily enter the inside of the pipe body 1.

Preferably, the aerosol-generating article further comprises a temperature-lowering flavor-supporting member 8 located between the support blocking member 3 and the filter member 4. In the absence of the temperature-lowering flavor-supporting member 8, the support blocking member 3 can play a role of temperature-lowering.

Preferably, the tube 1 is a paper tube.

Preferably, the support blocking member 3 is a polymer polymer material selected from polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate or polylactic acid. The material specifically used is not limited to these, and may be any material of the generally used support blocking member 3 capable of forming the structure of the support blocking member 3.
