Cigarette filter structure with built-in negative pressure drive fitting

Abstract

The invention discloses a cigarette filter structure with built-in negative pressure drive fitting. The structure includes a suction nozzle, a filter area and a cigarette area, wherein the inside of the filter area is provided with a suction port and a filter element, the suction nozzle sleeves the port position of the filter area, the filter area and the cigarette area are integrated into a cylindrical structure, the suction port runs through the filter element and cooperates with the suction nozzle, the suction port is of a rhombic structure and the outside of one end is provided with a through hole, the suction nozzle is provided with two ports, a negative pressure ball, a U-shaped negative pressure tube and pleated fit rings of the invention cooperate together, the deformation caused by the negative pressure ball causes a change in a standard atmospheric pressure filled in the inner part of the negative pressure ball, which causes the internal pressure of the pleated fit rings to increase, therefore, the two pleated fit rings of the same structure size interlace with each other, the cigarette end is fully sealed by using gradually decreased tightness gap, and the tightness sealof the cigarette end 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...
