Embodiment 1

[0033] The raw materials of the carbonaceous heat source of the present invention include the following components: 65g of carbon powder, 4g of guar gum, 8g of potassium alginate, 13g of calcium carbonate, 5g of potassium carbonate, 4g of potassium nitrate and 1g of iron oxide.

[0034] Mix the above components with a mold and make a cylindrical heat source with multiple five-pointed star-shaped longitudinal channels, the length of which is 15mm, and the internal void occupies 65% of the total volume of the heat source. figure 1 .

[0035] figure 2 It is a schematic diagram of a longitudinal section of a carbon-heated cigarette. It can be seen that the cigarette is composed of a carbonaceous heat source area a, a smoke forming area b and a filter tip area c. The carbonaceous heat source area a is composed of cigarette paper 6, aluminum foil paper 3 and carbonaceous heat source 1, and the length of the aluminum foil paper in the longitudinal direction is 1 / 3 to 1 / 2 of the le...

Embodiment 2

[0037] 20g guar gum, 50g vermiculite powder (200 mesh), 30g graphite powder (200 mesh) and 1g paraffin oil are sent into the extruder and mixed to make a bag with a thickness of 1000 μm and a width of 3.5mm, and tightly Wrap one end of the fixed section of the carbonaceous heat source prepared in Example 1 to obtain a carbonaceous heat source with both self-extinguishing and anti-shedding functions. The cross-sectional structure of the fixed section of the carbonaceous heat source is as follows: image 3 shown.

Embodiment 3

[0039] 15g guar gum, 45g vermiculite powder (400 orders), 40g graphite powder (150 orders) and 1.5g corn oil are sent into the extruder and mixed and made into a bag with a thickness of 700 μm and a width of 4.0mm. Tightly wrap one end of the fixed section of the carbonaceous heat source prepared in Example 1 to obtain a carbonaceous heat source with both self-extinguishing and anti-shedding functions.

Abstract

The invention discloses a carbonaceous heat source integrating self-extinguishing and anti-falloff functions. The carbonaceous heat source is of a cylindrical structure which is 10-20mm long; one end of the carbonaceous heat source is freely hung, called a free section, and the other end is fixed, called a fixed section; the ratio of the length of the fixed section to the length of the entire carbonaceous heat source is 1 to 4; and an expansive layer, which is 500-1500 [micro]m thick and is equal to the fixed section in length, covers the surface of the fixed section. The carbonaceous heat source disclosed by the invention is applicable to low-temperature heated cigarettes; and the carbonaceous heat source is capable of avoiding harm to human bodies in the case of the invasion of glass fibers when the cigarettes are covered by glass fibers and like heat-insulating materials and is also capable of avoiding the problem that rest parts of the cigarettes are ignited by the burning carbonaceous heat source which is to be burnt out.

Description

1. Technical field [0001] The invention relates to a carbonaceous heat source with both self-extinguishing and anti-shedding functions, belonging to the field of novel tobacco products. 2. Background technology [0002] Low-temperature heating cigarettes generally deliver satisfaction and tobacco aroma to consumers through heat-not-burn tobacco, which adapts and satisfies the physiological needs of consumers to a certain extent. It is heated at a low temperature (ideal temperature range 300-500°C), which can effectively and greatly reduce various harmful components in the flue gas. This is generally accomplished by physically separating the tobacco from the heat source, and therefore the heat source is at the heart of its design. Among them, the carbonaceous heat source has become one of the main heat sources for low-temperature cigarettes due to its advantages of safety, stability, speed, efficiency, and low price. In order to make the carbonaceous heat source easy to ign...
