Abstract

A filtering cigarette holder comprises a cigarette holder head and a suction nozzle which is in threaded connection or buckling connection with the cigarette holder head. An indent cigarette groove is arranged on the top portion of the cigarette holder head, a first flue is communicated with the bottom end of the cigarette groove, a second flue is arranged on an outer wall of the first flue, the suction nozzle is of a hollow structure, a third flue and a fourth flue are formed inside the hollow structure, a sleeve with an opening at one end is sleeved on the outer wall of the second flue, and smoke enters the filtering cigarette holder to pass through the first flue, the second flue, a detour flue, the third flue and the fourth flue respectively to flow out from the filtering cigarette holder. The filtering cigarette holder uses a first smoke oil groove and a second smoke oil groove to filter hazardous substances such as smoke oil and dust in smoke, the sleeve is arranged between the second flue and the third flue to increase the detour flue to lengthen a circulation path of original smoke in the filtering cigarette holder to increase filter efficiency in limited size of the filtering cigarette holder.

Description

Filter-tip

Technical field

The present invention relates to a kind of smoking apparatus, particularly a kind of filter-tip.

Background technology

As everyone knows, smoking is the behavior that is harmful to health, but having greatly in the society, still there is this custom in the people owing to a variety of causes, but along with the development of society, the raising of health of people consciousness, increasing smoker understands the flue gas that the choice for use filter-tip purifies suction, and there are the problems such as single, that clean-up effect is undesirable that purify in the filter-tip great majority that exist at present.

Summary of the invention

The objective of the invention is: for overcoming the deficiencies in the prior art, provide a kind of novel filter-tip.

Technical scheme of the present invention is: a kind of filter-tip, include cigarette holder head, the suction nozzle that is threaded or is fastened and connected with cigarette holder head, the cigarette holder head top is provided with the cigarette groove of an indent, cigarette bottom land end is communicated with the first flue, the first flue outer wall is provided with the second flue outward, the diameter of described the second flue is greater than the diameter of the first flue, suction nozzle is that hollow structure inside is formed with the 3rd flue and the 4th flue, the diameter of the 3rd flue is greater than the diameter of the 4th flue, be socketed with the sleeve of an end opening at the second flue outer wall, be provided with projection between sleeve lining and the second flue outer wall, be provided with cushion block between sleeve openings end and the cigarette holder head internal chamber wall, the barrel bore diameter is provided with twisting flue greater than the second flue outer wall circle diameter and between, and flue gas enters behind the filter-tip respectively through the first flue, the second flue, twisting flue, outflow filter cigarette holder behind the 3rd flue and the 4th flue.

The first flue one end in the first flue and the second flue junction is provided with the first boss, the 4th flue one end in the 4th flue and the 3rd flue junction is provided with the second boss, be formed with the first tobacco tar groove between the first boss and the second flue, be formed with the second tobacco tar groove between the second boss and the 3rd flue.

The cigarette front of the slot is cylindrical-shaped structure, and the bottom is truncated cone structure, cigarette groove cover with its form fit of socket in the cigarette groove, and described cigarette groove cover has into mouth for metal structure and bottom it, describedly advances mouth and is communicated with the first flue.

Projection is fixed on the second flue outer wall, and cushion block is fixed on the cigarette holder head internal chamber wall.

Projection is fixed on the sleeve lining, and cushion block is fixed on the sleeve openings end.

Positive beneficial effect of the present invention:

1. filter-tip of the present invention is simple in structure, setting by the first and second boss structures, realized that dexterously the first tobacco tar groove and the second tobacco tar groove to the filtration of the harmful substance such as tobacco tar and flue dust in the flue gas, have improved the filter efficacy of filter-tip to harmful substance greatly.

2. filter-tip of the present invention, between the second flue and the 3rd flue, be provided with sleeve, thereby increased a twisting flue, arranging of twisting flue increased the circulating path length of raw flue gas in filter-tip, increased filter efficiency in limited filter-tip volume.
