Description

a low temperature fume

technical field

The invention relates to a low-temperature smoking body, which belongs to the technical field of electronic cigarettes.

Background technique

In traditional cigarettes, there are dozens of carcinogens in the smoke of tobacco burning, and the smoke diffuses in the air to form more harmful second-hand smoke, which will cause greater health damage to the surrounding people and pollute the environment.

With the advancement of science and technology and people's pursuit of a healthy life, a smokeless cigarette system has emerged, which generates smoke by roasting solid smoking materials such as cigarettes without burning. At present, the low-temperature non-burning cigarette products on the market are mainly filled with tobacco materials such as cigarette sticks, shredded tobacco or tobacco sheets in special electric heating devices, and the smoke in the tobacco filling materials is volatilized by electric heating, thereby making the smoking Those who get a smoking experience similar to traditional tobacco. However, the electric heating in the prior art is basically peripheral heating, the heating speed is slow and uneven, the smoke generation time is long and the concentration is insufficient; at the same time, it is troublesome to fill the tobacco material and remove it after smoking, which seriously affects the user experience.

Contents of the invention

The technical problem solved by the invention is that the tobacco extract is in a liquid state, and it is inconvenient to take and use when smoking; and it is not evenly heated when heated.

The technical solution of the present invention is to provide a low-temperature smoke body, including a carrier and tobacco extract adsorbed on the carrier; the carrier is composed of plant adsorption materials, heat-conducting components and binders; the low-temperature smoke body The mass ratio of the plant adsorbent material to the tobacco extract is not more than 1:1.

The preparation method of the low-temperature smoke body includes the following steps: (1) uniformly mixing the plant adsorption material, the heat-conducting component and the binder, and forming a carrier to obtain a carrier; (2) soaking the carrier in tobacco extract, and taking it out A low-temperature smoke body is obtained; in the low-temperature smoke body, the mass ratio of the plant adsorption material to the tobacco extract is not more than 1:1.

The plant adsorption material refers to the plant material with adsorption properties. The plant adsorption material of the present invention is selected from the fruit of the plant and obtained after crushing. It can be the whole fruit or a part of the fruit such as the peel/husk. In the present invention, the plant adsorption material is used as the carrier material of the tobacco extract (or e-liquid, e-liquid, etc.), so that the tobacco extract is adsorbed on the plant carrier. Considering the thermal conductivity and molding of the plant adsorption material, the The plant adsorption material is mixed with heat-conducting components and binders, and then soaked and adsorbed to obtain a low-temperature smoke body that is convenient to take, heats and smokes evenly. The adsorption capacity of plant adsorption materials is an important indicator for selecting carrier materials. Generally, plant materials with large adsorption capacity and no peculiar smell are selected. The tobacco extract adsorbed by plant adsorption materials should not be lower than the weight of plant adsorption materials themselves, so as to avoid weak smoke smell.

Further, the heat-conducting component is heat-conducting powder and/or heat-conducting fiber. Thermally conductive powder and thermally conductive fiber represent two types of materials with different thermal conduction methods. The heat-conducting powder is evenly distributed in the low-temperature smoke body, which can increase the thermal conductivity of the low-temperature smoke body. Through the propagation of smoke, the heat-conducting powder is easy to be heated, so that the smoke oil around the heat-conducting powder is heated evenly. Due to the longer length of the heat-conducting fiber, in addition to the above-mentioned heat-conducting methods, the heat-conducting fiber can also conduct heat in the direction of the fiber, making it easier for the low-temperature smoker to be heated evenly as a whole.

Further, the heat-conducting powder is spherical alumina powder; the heat-conducting fiber is carbon fiber.

Further, the particle size of the heat-conducting powder is 0.15-0.25 mm; the diameter of the heat-conducting fiber is 0.05-0.2 mm, and the length is 1-10 mm.

Further, the thermal conductivity of the thermal conductive component is 500-5000 W/(m·K). These materials are actually superconducting thermal materials. The present invention finds that when the thermal conductivity of the heat-conducting component reaches above 500 W/(m·K), the heat-conducting component with a thermal conductivity greater than 1000 W/(m·K) is preferred, the heat-conducting effect of the smoke column is significantly improved, and the cigarette fragrance is released evenly .

Further, the mass ratio of the plant adsorption material, heat-conducting component and binder is 100: (1-15): (1-20), preferably the mass ratio is 100: (5-10): (5-15 ).

Further, before step (1), adjust the water content of the plant adsorbent to 10-15%, and carry out disinfection and sterilization treatment; in step (1), adjust the water content of the carrier to 3-6%; step (2) The low-temperature smoke body obtained in the end is then packaged; the packaging material can be PET, PA, PE, BOPP, LDPE and other film materials or aluminum foil paper.

Further, the binder is one or more of white latex for cigarettes, pregelatinized modified starch, cyclodextrin, chitosan, and hot melt adhesive.

Further, the plant adsorption material is one or more of corn cob powder, walnut shell powder, rice husk powder, grapefruit peel powder.

Further, the immersion time of the plant adsorption material in the tobacco extract is 5-15 minutes, so that the tobacco extract is adsorbed on the carrier. After soaking, drain for 4-8 hours before packing.

Further, the particle size of the plant adsorption material is 20-40 mesh, and the density of the carrier is 0.2-1.0 g/cm ³ . The particle size of the plant adsorption material is related to the adsorption performance and the density of the carrier; the density of the carrier should not be too large, so as to avoid the lack of space in the smoke body, the smoke is not easy to diffuse, and the heat is not easy to transfer. Of course, if the density is too low, it means that the content of e-liquid is less, the smoke that can be smoked is not much, and the smoke taste is very light.

Compared with prior art, the beneficial effect of the present invention is:

1. The low-temperature smoking body provided by the present invention has been shaped according to the size of the heating chamber of the smoking appliance, absorbs the smoke oil and is sealed and packaged. It can be stored for a long time without affecting the smoking experience, and it is easy to add and remove.

2. The low-temperature smoke body provided by the present invention has a loose structure, a large number of pores inside, and easy suction, and can increase the heating area and heating uniformity of the suction material.

3. The carrier provided by the present invention has excellent adsorption performance on e-liquid, and the low-temperature smoking body can give consumers a good sense of satisfaction when smoking; at the same time, the raw material is cheap, safe and environmentally friendly, and is suitable as a disposable consumer product.

4. The low-temperature smoker provided by the present invention contains superconducting heat-conducting powder material inside, and the internal heat conduction will be greatly accelerated, which is conducive to improving the uniformity of heating and quickly forming smoke at a lower temperature.
