A cigarette filter tip structure with built-in negative pressure drive fit

Abstract

The invention discloses a cigarette filter structure with a built-in negative pressure drive and lamination. The structure includes a suction nozzle, a filter area, and a cigarette area. The filter area is provided with a suction port and a filter core, and the suction nozzle is sleeved at the port position of the filter area. The filter area and the cigarette area are integrated to form a cylindrical structure. The suction port runs through the filter element and matches with the suction nozzle. , The U-shaped negative pressure tube and the pleated fitting ring cooperate together, and the deformation of the negative pressure ball causes a change in the standard atmospheric pressure filled inside it, which promotes the internal pressure of the pleated pleated fitting ring to increase, so the two The pleated fitting circles of the same structural size are interlaced with each other, and the gradually smaller fitting gaps are used to fully seal the cigarette butt, and the tight sealing of the cigarette butt is preliminarily realized.

Description

technical field [0001] The invention relates to a cigarette filter tip structure, in particular, a cigarette filter tip structure with a built-in negative pressure driven lamination. Background technique [0002] Cigarette filters become a mechanical device for reducing smoke particles, mainly to reduce the inhalation of tar and nicotine. They are used as mouth-shaped parts to tightly fix round cigarette butts to meet the maximum utilization of smoke by users; [0003] Because the cigarette butt is relatively soft, as long as it is pressed or subjected to external force, the cigarette butt can be deformed and difficult to return to its original shape. Under the condition of not wasting cigarettes, the deformed cigarette butt can no longer achieve a tight fit in the cigarette filter, making it The remaining gaps cause excess smoke waste during use. Contents of the invention [0004] In view of the above problems, the present invention provides a cigarette filter tip struct...
