Description

Heating cigarette with sealing function

Technical Field

The utility model belongs to the technical field of the heating cigarette, in particular to heating cigarette with sealed function props up.

Background

The heating cigarette, also called low-temperature cigarette, is a novel tobacco product which utilizes an external heat source to heat tobacco shreds, and nicotine and flavor substances in the tobacco shreds are volatilized to generate smoke gas to meet the requirements of smokers during heating. Because the temperature of the tobacco is far lower than that of the traditional cigarette, harmful components generated by high-temperature combustion and cracking of the tobacco can be reduced, and harmful chemical components and toxicity of smoke are greatly reduced; meanwhile, the sidestream smoke is greatly reduced, and the harm of second-hand smoke to non-smoking people is reduced.

The existing heating cigarette is composed of a cigarette core section and a filter rod section in a rolling connection mode, wherein the filter rod section is composed of a supporting section, a cooling section and a filter tip section according to functionality. When the cigarette heater is used, a heated cigarette is inserted into a heater cavity for providing a heat source, and a heating sheet/piece and the like in the heater convert electric energy into heat energy to heat the heated cigarette, so that smoke for smoking is generated.

In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems:

1. the existing heating cigarette is inserted into the cigarette core section of the heater and is in an open shape. After the use, when taking out cigarette from the heater, can cause the cigarette core material to drop in the heater cavity because of the cigarette core material is heated the carbonization, the pipe tobacco bonds the scheduling problem at the heating plate, leads to heating chamber and heating plate contaminated, is difficult to clean, heating function reduces, the spoilage risees.

2. Because the heating temperature of the heated cigarette is lower than the combustion temperature, compared with the traditional cigarette, the tobacco aroma components of the heated cigarette are difficult to completely release, and the smoke quantity is insufficient, so the cigarette is difficult to be accepted by traditional smokers.

In order to solve the above problems, the present invention is provided.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a first aspect provides a heating cigarette props up with sealing function, it includes cigarette core section 1 to prop up the cigarette, cigarette core section 1 contains one end opening, other end confined U type pipe 1-1 and fills cigarette core material piece 1-2 in the U type pipe 1-1.

Preferably, the block of smokable material 1-2 further comprises flakes, particles of smokable material, pieces of incense, or particles of flavourant.

Preferably, the closed end of the U-shaped pipe 1-1 is a plane or an arc surface.

Preferably, the piece of core material 1-2 comprises tobacco powder, tobacco shred, tobacco particles, tobacco pellets, tobacco gathered sheet material, and tobacco pleated sheet material.

Tobacco powder, pipe tobacco, tobacco granule, tobacco ball, tobacco gather together sheet and tobacco fold sheet, fuming agent piece, fuming agent granule, spice piece, or the known shape that the spices granule was current material, be prior art.

Preferably, the U-shaped pipe 1-1 comprises a metal U-shaped pipe and a high-temperature-resistant polymer U-shaped pipe; the high temperature resistance means that the material does not deform at 350 ℃ under atmospheric pressure.

Preferably, the U-shaped tube 1-1 is manufactured by a discontinuous process such as injection molding or die pressing.

Preferably, the tobacco rod further comprises a filter rod segment 2 and tipping paper 3.

Preferably, the filter rod section 2 comprises a support section, a cooling section and a filter section which are sequentially abutted.

Wherein the support section abuts the wick section 1.

The second aspect of the present invention provides the method for preparing a cigarette of the first aspect, comprising the steps of: the cigarette core material block 1-2 is placed in the U-shaped pipe 1-1 through filling or stuffing technology, and then the cigarette core section 1 and the filter stick section 2 are rolled and connected by tipping paper 3 to form the cigarette.

The utility model discloses following beneficial effect has:

1. the core material of the common cigarette is prepared by wrapping the cigarette paper and continuously cutting on line. The utility model discloses it is intraductal to arrange the one end confined U type with the cigarette core material for the first time, and the cigarette core material can not drop in the heating chamber, has solved because of being heated the carbonization cigarette core material drop in the heating chamber when the plug, bond on the heating plate, the heating chamber that leads to pollutes, be difficult to clean, the spoilage risees the scheduling problem.

2. Among the preferred technical scheme, the utility model discloses a U type pipe is the metal material, can effectively absorb the heat and conduct fast for the cigarette core material, plays and improves heat utilization rate, cigarette core material even heating, improves effect such as suction uniformity one by one.

3. The utility model discloses a cigarette core section connects with filter rod sealing, and cigarette core section bottom is sealed by U type pipe, can play sealed, the separation outside air's effect simultaneously, provides airtight oxygen-poor heating environment. Due to the replacement of the air inside the tobacco core section by the fresh flue gas formed, the oxygen content in the tobacco is reduced with the heating process. At the moment, even if the heating temperature is increased, the combustion phenomenon can not occur, the release of the tobacco aroma components can be increased, and the taste of the cigarette is closer to that of the traditional cigarette.
