DUAL-USE CIGARETTE

Abstract

The present invention discloses a dual-use cigarette, comprising a suckable material segment and a filter tip segment which are wrapped by roll paper, wherein a hollowed segment surrounded by roll paper is disposed between the suckable material segment and the filter tip segment, and the roll paper of the hollowed segment is provided with a plurality of first capillary pores. The dual-use cigarette has the advantages that cold air cannot be sucked when smoking is started, and the burn of a respiratory mucosa caused by high temperature smoke can be avoided.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0015] FIG. 1 is a sectional view of an embodiment of the present invention.

[0016] FIG. 2 is an enlarged view of a part A of FIG. 1.

DETAILED DESCRIPTION

[0017] The present invention is further explained in detail in combination with the embodiments and in accordance with the accompanying drawings.

[0018] A dual-use cigarette, referring to FIGS. 1 and 2, comprises a suckable material segment 6 and a filter tip segment 1 which are wrapped by roll paper 5, wherein a hollowed segment surrounded by the roll paper 5 is disposed between the suckable material segment 6 and the filter tip segment 1, and the roll paper of the hollowed segment is provided with a plurality of first capillary pores 4.

[0019] The present invention mainly uses an electric heating device to bake the suckable material segment, such that volatile substances (such as aroma substances and nicotine, etc., of the tobacco) are volatilized for people to suck. Since the hollowed segment is disposed between the suckable material segment and the filter tip segment, the volatile substances (smoke) volatilized by heating before the suction are stored in the hollowed segment, and the scented gas can be sucked when people start to suck. Since the plurality of first capillary pores is disposed in the roll paper of the hollowed segment, the cold air in the hollowed segment originally is discharged from the first capillary holes while the volatile substances are stored in the hollowed segment, so as to avoid the discomfort caused by suction of the cold air when the smoking is started. Due to the small aperture of the small first capillary pores, the gas flow will be formed only under a certain pressure difference. The plurality of first capillary pores is disposed in the roll paper of the hollowed segment, and during the suction, the cold air from the outside can be sucked to cool the sucked high-temperature smoke, and the high temperature smoke is prevented from burning the respiratory mucosa.

[0020] According to the dual-use cigarette of the present invention, referring to FIG. 1 to FIG. 2, based on the foregoing technical solution, specifically, the roll paper 5 of the filter tip section 1 is also provided with a plurality of second capillary pores 2. By using the second capillary pores 2 in the roll paper 5 of the filter tip section 1, the smoke is further cooled, and the comfort level of the smoke entering an oral cavity is ensured. In order to guarantee the full gas suction of the second capillary pores 2 of the filter tip section 1, a diameter of the first capillary pores 4 is set to be smaller than or equal to a diameter of the second capillary pores 2.

[0021] According to the dual-use cigarette of the present invention, referring to FIG. 1 to FIG. 2, based on the foregoing technical solution, specifically, the first capillary pores 4 are away from the end of the filter tip segment 1 by 2 mm-3 mm, a degree of aeration of the first capillary pores 4 is 100 CU-600 CU, the first capillary 4 pores are in two rows, and a length of the hollowed segment is 5 mm-35 mm.

[0022] According to the dual-use cigarette of the present invention, referring to FIG. 1 to FIG. 2, based on the foregoing technical solution, specifically, the suckable material segment 1 is a tobacco product segment.

[0023] According to the dual-use cigarette of the present invention, referring to FIG. 1 to FIG. 2, based on the foregoing technical solution, specifically, a suckable material in the suckable material segment 1 is filiform, and may also be granular or flaky in other embodiments.

[0024] According to the dual-use cigarette of the present invention, referring to FIG. 1 to FIG. 2, based on the foregoing technical solution, specifically, the roll paper 5 is roll paper for the cigarettes. In order to improve quality of the smoke, in other embodiments, the roll paper may also be roll paper for cigars.

[0025] According to the dual-use cigarette of the present invention, referring to FIG. 1 to FIG. 2, based on the foregoing technical solution, specifically, a length of the filter tip segment is 5 mm-25 mm, and a suction resistance of the filter tip segment is 2000 Pa-5000 Pa.

[0026] The foregoing elaborates the two-dual cigarette according to the present invention and is intended to help to understand the present invention. However, the embodiments of the present invention are not limited to the above embodiments, and any changes, modifications, substitutions, combinations and simplifications made without departing from the principle of the present invention should be equivalent replacement modes and are included within a protective scope of the present invention.
