Description

Filter tip

Technical Field

The utility model relates to the technical field of cigarette tools, in particular to a filter tip.

Background

The filter tip is matched with the cigarette to filter most harmful substances in the cigarette, so that the damage of the toxic substances in the cigarette to the human body can be effectively reduced, and the health of the human body is protected.

The core structure of the filter cigarette holder is a filter element part for filtering smoke, and the structure commonly used at present is that a plurality of filter structures are arranged along the axial inner part of the cigarette holder, so that the smoke is gradually filtered in the process of being sucked. After multiple uses, the filter element can retain impurities such as particles and tar.

However, the conventional filter structure has the defects that only the bottommost part of the filter element is in direct contact with flue gas, the filter area is small, the single filter effect is insufficient, and the bottom of the filter element is easy to be blocked after long-term use, so that the service life of the filter element is reduced; because the position which is firstly contacted with the flue gas is at the lowest end of the filter element, tar can be adhered to the lowest end of the filter element by integrating liquid, which can cause tar to splash and cause pollution when the filter element is replaced. The whole is not environment-friendly.
