Description

Technical Field

[0001] The present invention belongs to the technical field of atomized smoke products, and in particular relates to a self-heating aerosol product and a preparation method thereof. Background Art

[0002] Currently, atomized smoke products primarily include electronic cigarettes and low-temperature cigarettes. Both utilize electric heating devices to heat a substrate containing an atomizer, thereby evaporating atomized smoke. However, this atomization method requires the atomizer substrate to operate at a relatively high temperature and for a long time. Low-temperature cigarettes typically heat at around 300-350°C, requiring approximately 15 seconds to produce smoke, and must remain at this operating temperature for four minutes to complete a single puff. Electronic cigarettes, on the other hand, typically heat at around 180-250°C and must maintain this operating temperature until the puff stops.

[0003] However, prolonged high-temperature heating requires significant energy, resulting in high power consumption and frequent recharging of electric heating devices. Furthermore, excessively high smoke temperatures increase the difficulty in cooling the mouthpiece of low-temperature cigarettes. Heating elements typically rely on heat transfer, making it difficult for heat to reach areas of the substrate far from the heating element, resulting in uneven heating across the substrate. Summary of the Invention

[0004] In view of this, the present invention aims to provide a self-heating aerosol product and a preparation method thereof, wherein the self-heating aerosol product can reduce the operating temperature and time of the heating element while releasing a volume of smoke that meets the inhalation requirements.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] In a first aspect, the present invention provides a self-heating aerosol product, comprising an aerosol product matrix and ozone oil added to the aerosol product matrix;

[0007] Calculated by the amount of ozone, the amount of ozone oil added is 0.001% to 5% of the mass of the aerosol product matrix.

[0008] Preferably, the ozone content in the ozone oil is 0.1-160 mg / g.

[0009] More preferably, the ozone content in the ozone oil is 20-100 mg / g.

[0010] Preferably, the oil agent of the ozone oil is selected from unsaturated fatty acids.

[0011] Preferably, the oil is selected from any one or more of ω-9 unsaturated fatty acids, ω-6 unsaturated fatty acids or ω-3 unsaturated fatty acids.

[0012] Preferably, the aerosol product matrix is ​​selected from low-temperature cigarette tobacco or electronic cigarette oil.

[0013] In a second aspect, the present invention provides a method for preparing a spontaneous low-temperature heated cigarette, comprising the following steps:

[0014] The ozone oil is sprayed on the surface of low-temperature cigarette shreds and allowed to stand to prepare cigarettes.

[0015] Preferably, the mass ratio of the ozone oil to the low-temperature cigarette tobacco is 1:1000 to 1:20.

[0016] Preferably, the standing time is 1 to 5 h.

[0017] In a third aspect, the present invention provides a method for preparing a self-heating electronic cigarette, comprising the following steps:

[0018] Preferably, the mass ratio of the ozone oil to the electronic cigarette oil is 1:1000 to 1:20.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) In the present invention, the method of adding ozone oil is simple, and the preparation method of self-heating aerosol products (i.e., self-heating cigarettes and self-heating electronic cigarettes) is simple, which is convenient for industrial production;

[0021] (2) The ozone oil added in the present invention can stably release oxygen when heated, which is beneficial to the comfort of the flue gas and increases the flue gas volume;

[0022] (3) A large amount of heat is released during the process of ozone decomposition and oxygen release, making the heating element not only a heat transfer device, but also a trigger device for the exothermic reaction, which is conducive to the tobacco raw materials away from the heating element to release atomized smoke through their own heat;

[0023] (4) The present invention can significantly reduce the operating temperature of the heating element. After the heating element triggers the ozone decomposition reaction in the tobacco raw material, the heating of the heating element can be stopped, which greatly shortens the continuous heating time of the heating element and saves energy of the electric heating device. DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] To address the high operating temperatures and uneven heating of the substrate in existing aerosol smoke products, the present invention provides a self-heating aerosol product comprising an aerosol product substrate and ozone oil added to the aerosol product substrate. The aerosol product substrate is selected from low-temperature cigarette tobacco or e-cigarette oil, or other common aerosol substrates in the art.

[0026] In the present invention, the introduction of ozone into the ozone oil plays a key role in the self-heating effect of the aerosol product.

[0027] Ozone (O3), also known as superoxide, has a grassy smell at room temperature. At normal temperature and pressure, it is relatively unstable and decomposes spontaneously into oxygen. While inhaling small amounts is beneficial, inhaling excessive amounts can be harmful. The general reaction equation for ozone is: 2O3 → 3O2 + 285 kJ.

[0028] It can be seen that the introduction of ozone not only brings sufficient oxygen, but its decomposition reaction can also generate heat.

[0029] However, ozone typically exists as a gas at room temperature and pressure, making it inconvenient to introduce into an aerosol matrix. This invention combines ozone with an oil (i.e., unsaturated fatty acids) to form a stable molecular structure, namely, ozone oil. Typically, ozone oil has a half-life of three years when stored in the dark at room temperature and pressure. However, the half-life of ozone oil at 0°C can reach ten years. Ozone decomposes more rapidly at higher temperatures, with ozone already decomposing at 270°C.

[0030] In the present invention, the unsaturated fatty acids can specifically be the ω-9 series unsaturated fatty acids represented by oleic acid contained in tea oil, the ω-6 series unsaturated fatty acids represented by linoleic acid contained in vegetable oil, the ω-3 series unsaturated fatty acids represented by 20-carbon 5-enoic acid (EPA) and 22-carbon 6-enoic acid (DHA) contained in fish oil, etc.

[0031] In the present invention, the ozone content in the ozone oil is 0.1-160 mg / g, preferably 20-100 mg / g.

[0032] In the present invention, the amount of ozone oil added is 0.001% to 5% of the mass of the aerosol product matrix, preferably 0.005% to 2%, calculated as the amount of ozone.

[0033] The present invention not only facilitates the introduction of ozone components into the aerosol matrix by adding the above-mentioned ozone oil, but also effectively realizes self-heating by means of the decomposition of ozone, thereby significantly reducing the operating temperature of the heating element while increasing the flue gas volume.

[0034] Illustratively, the present invention provides a method for preparing a self-heating low-temperature cigarette, comprising the following steps:

[0035] The ozone oil is sprayed on the surface of low-temperature cigarette shreds and allowed to stand to prepare cigarettes.

[0036] According to the present invention, ozone oil is sprayed onto the surface of low-temperature cigarette shreds and allowed to stand for a while to prepare cigarettes. The ozone oil is as described above and will not be further elaborated here. The spraying can be performed using methods well known to those skilled in the art. It is important to ensure that the ozone oil is sprayed evenly during the spraying process.

[0037] In some embodiments of the present invention, the mass ratio of the ozone oil to the low-temperature cigarette tobacco is 1:1000-1:20, preferably 1:800-1:50.

[0038] After spraying, according to the present invention, the mixture is generally left to stand for 1 to 5 hours, preferably 2 to 3 hours, in order to allow the ozone oil to penetrate the tobacco fibers.

[0039] The present invention has no particular limitation on the source of the low-temperature cigarette shreds and the preparation steps of the low-temperature cigarettes, and the steps may be performed according to the contents known to those skilled in the art.

[0040] The present invention tests the obtained self-heating low-temperature cigarettes and finds that when smoked using a low-temperature cigarette device with a heating temperature of 100° C., the smoke volume can still meet the smoking requirements.

[0041] Illustratively, the present invention provides a method for preparing a self-heating electronic cigarette, comprising the following steps:

[0042] The ozone oil is added to the electronic cigarette oil to prepare the electronic cigarette.

[0043] In the present invention, the mass ratio of the ozone oil to the electronic cigarette oil is generally 1:1000-1:20, preferably 1:800-1:50.

[0044] The present invention has no particular limitation on the composition and content of the electronic cigarette oil, which are well known to those skilled in the art.

[0045] The present invention tested the self-heating electronic cigarette and found that the amount of smoke increased significantly when the electronic cigarette was smoked at a temperature of 150-200°C. Even when the heating temperature of the electronic cigarette was lowered by 40-50°C, the amount of smoke was still relatively large.

[0046] It can be seen that the self-heating electronic cigarette and self-heating low-temperature cigarette prepared by the preparation method of the present invention can not only achieve self-heating and reduce the operating temperature of the heating device, but also meet the user's sensory smoking requirements.

[0047] In order to further illustrate the present invention, the following examples are provided for detailed description. The experimental raw materials used in the following examples of the present invention are all commonly available commercial products.

[0048] Example 1

[0049] Ozone oil (the solvent is safflower oil) with an ozone content of 20 mg / g is sprayed on the surface of low-temperature cigarette tobacco at a spraying ratio of 1% under normal temperature working environment. After standing for three hours, low-temperature cigarettes are prepared according to the usual process.

[0050] Sensory smoking effect: When smoking with a low-temperature cigarette device with a heating temperature of 150℃, the smoke volume can still meet the smoking requirements.

[0051] Example 2

[0052] Ozone oil (solvent: 20-elemental 5-hydroxy-1-propenoic acid (EPA)) with an ozone content of 50 mg / g was added to electronic cigarette oil at a mass ratio of 2%, and an electronic cigarette was prepared according to a conventional process.

[0053] Sensory vaping experience: The amount of smoke produced by the e-cigarette is significantly greater than that produced by an e-cigarette without ozone oil. Even when the heating temperature of the e-cigarette is lowered by 40°C, the amount of smoke is still relatively large.

[0054] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is to be construed in the widest manner consistent with the principles and novel features disclosed herein.
