Description

FIELD

The present application relates to the technical field of cigarettes, and more particularly to a cigarette holder. The present application further relates to a cigarette including the cigarette holder.

BACKGROUND

The style and characteristic of Chinese-style cigarettes have always been the focus of the cigarette industry. The Chinese-style cigarette is a cigarette which can satisfy the present and potential consumption demands of the Chinese cigarette customers, having a unique aroma style and flavor characteristic, and possessing core techniques. Strong aroma, low tar and less harm have always been the core object of the cigarette industry.
The raw material resource and the tobacco blend formulation design play a role in the unique aroma style and flavor characteristic of the Chinese-style cigarette. And the aroma style and the flavor characteristic with Chinese features make the Chinese-style cigarette distinctly differ from the British-style, the American-style and the Japanese-style cigarettes in tar content. Customers are used to a strong aroma and flavor and are unaccustomed to a low tar flavor, and presently without adding other spices to supplement the flavor, a low concentration flavor caused by a low tar cigarette is in contradiction with the strong flavor that customers are used to. Tar decrease and harm reduction of the cigarettes are urgent demands and trends whether in the aspect of the development of the tobacco industry or in the aspect of customers' own health demands.

the filter includes a shell 3 and an impeller arranged inside the shell 3, the impeller includes a central shaft 1 and blades 2 arranged on the central shaft 1;
an extension line of the central shaft 1 extends toward the primary filter holder section and the secondary filter holder section. It should be understood that, in a case that the primary filter holder section, the filter and the secondary filter holder section are connected in the listed sequence and vertically arranged, the central shaft 1 is also vertically arranged;
the blade is composed of a front end portion 21 and a rear end portion 22 arranged front and back along a rotation track, and the front end portion 21 is heavier than the rear end portion 22. It should be understood that, the blade 2 rotates clockwise or anticlockwise by 360 degrees with respect to the central shaft 1, and the front end portion 21 and the rear end portion 22 are arranged according to the order of rotation.

Further, in order to reduce a resistance of the blade during rotation, each of the front end portion 21 and the rear end portion 22 is a continuous smooth curved surface. Preferably, a bending direction of the front end portion 21 is opposite to a bending direction of the rear end portion 22, making the blade in an S shape.
During the process that the impeller stops rotating, for making more obvious vibration feel for people, an edge of the front end portion 21 and an edge of the rear end portion 22 are located in different planes, and a projection area of the blade 2 is enlarged. Preferably, a height difference between the edge of the front end portion 21 and the edge of the rear end portion 22 is equal to or larger than 1/2 of a height of the shell 3.
