Description

Heating cigarette with punched filter tip

Technical Field

The utility model belongs to the technical field of novel tobacco products, and particularly relates to a heating cigarette with a punched filter tip.

Background

The cigarette is heated to enable the tobacco raw material to generate nicotine and aerosol, the natural combustion is replaced by a relatively closed heating environment to enable tobacco components to release smoke through dry distillation or a little cracking, the heating temperature is 200-400 ℃, harmful components generated by heating the cigarette are greatly reduced, and meanwhile, the released smoke quantity and the smoke concentration are lower. Typically such cigarettes are shorter in length than conventional cigarettes and have a lower smoke resistance.

Although the temperature of the combustion cone can reach 900 ℃ during the smoking of the traditional cigarette, the temperature of smoke is greatly reduced after the smoke passes through the unburned tobacco sections and the filter sticks in a relatively open environment, and the mainstream smoke entering the oral cavity can not cause a consumer to feel hot. However, although the temperature of the smoke generated by heating the cigarette is lower than that of the traditional cigarette, the smoke has a relatively high water content and a relatively short smoke passage, so that the sensory temperature of the mainstream smoke reaching the oral cavity is higher than that of the traditional cigarette.

Therefore, the filter rod for heating the cigarette needs to have the function of cooling the smoke. The cavity section of the cigarette filter tip is provided with air holes, cold air is introduced to cool the smoke, the existing cavity punching technology for cooling the smoke generally arranges micropores with the diameter less than 0.2mm and the number more than 10 on the cooling cavity section, and the micropores can cool the smoke, but the cold air is introduced to generate condensation and dilution effects on aerosol, so that the smoke quantity is reduced; the micropores are few, the cooling effect on the smoke is limited, the temperature of the smoke at the inlet is high, and the phenomenon of mouth burning exists.

Therefore, the situation that the cigarette smoking amount and the smoke inlet temperature are not ideal often occurs in the conventional micropore-punching and multi-hole-punching heating cigarette punching filter rod.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is: aims to provide a heating cigarette with a punched filter tip for solving the problem of poor smoking effect caused by the structural defects of the existing heating cigarette.

In order to achieve the technical purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a heating cigarette that filter tip punched, includes section of fuming, cooling cavity section, filter segment and cladding element, a plurality of holes have evenly been seted up in cooling cavity section circumference to the cladding element, the diameter size of hole is not less than 0.2mm, the number of hole is not more than 8.

Further defined, the diameter of the hole is not larger than 0.8 mm.

Further, the number of the holes is at least 2.

Further, the size of the central axis of the hole from the end face of the smoking section close to one end of the filter section is not less than 5 mm.

Further, the size of the central axis of the hole from the end face of the end, close to the smoking section, of the filter section is not less than 5 mm.

Further, the number of the holes is even. Due to the structural design, punching is more convenient.

Further defined, the sum of the diameter sizes of all the holes is less than 1/3 of the circumferential size of the cooling cavity section. Due to the structural design, the problem that the cooling cavity section is easily broken at the holes formed in the circumferential direction after the sum of the diameters of all the holes is too large can be solved.

Adopt above-mentioned technical scheme's utility model, have following advantage:

1. the holes with the diameter size not less than 0.2mm and the number not more than 8 are formed in the cooling cavity section to introduce the external air flow into the cooling cavity section, and different from the external air flow introduced by the micropores, the holes formed by the scheme can form stronger air flow disturbance in the cavity of the cooling cavity section, so that more aerosol can be formed in the subsequent cooling cavity section after the smoking section is heated, and the smoking smoke amount of cigarettes is increased;

2. through the design of punching with less holes and large holes, in the heating and smoking process of the heated cigarette, external cold air enters the cooling cavity section through the holes in the cooling cavity section, is mixed with hot smoke released by the smoking section after being heated, and can reduce the smoke temperature through heat exchange of cold air flow and hot air flow, so that the smoke temperature at the inlet is proper.

FIG. 1 is a schematic structural view of an embodiment of a heated cigarette with a perforated filter rod according to the present invention;

the main element symbols are as follows:

the device comprises a smoking section 1, a cooling cavity section 2, holes 20, a filtering section 3 and a cladding element 4.

Detailed Description

The present invention will be described in detail with reference to the drawings and specific embodiments, wherein like reference numerals are used for similar or identical parts in the drawings or the description, and implementations not shown or described in the drawings are known to those of ordinary skill in the art. In addition, directional terms, such as "upper", "lower", "top", "bottom", "left", "right", "front", "rear", and the like, used in the embodiments are only directions referring to the drawings, and are not intended to limit the scope of the present invention.

In this embodiment, as shown in fig. 1, the cigarette with a perforated filter tip comprises a smoking section 1, a cooling cavity section 2, a filtering section 3 and a wrapping element 4, wherein the wrapping element 4 is uniformly provided with a plurality of holes 20 in the circumferential direction of the cooling cavity section 3, the diameter of each hole 20 is not less than 0.2mm, the diameter of each hole 20 is not more than 0.8mm, and 0.5mm is selected in this embodiment;
