Description

Technical Field

[0001] The present invention belongs to the technical field of atomized smoke products, and specifically relates to a self-heating aerosol product, a method for preparing a self-heating cigarette, and a method for preparing a self-heating electronic cigarette. Background Art

[0002] At present, the main products of atomized smoke are electronic cigarettes and low-temperature cigarettes. Both use electric heating devices to heat the matrix with atomizers added to evaporate atomized smoke. However, this atomization method requires the matrix of the atomizer to work at a higher temperature and a longer working time. Among them, low-temperature cigarettes are generally around 300~350℃, and it takes about 15 seconds to heat up before smoke comes out, and it takes 4 minutes to maintain the working temperature to complete the smoking of a cigarette; while electronic cigarettes are generally around 180~250℃, and the working temperature needs to be maintained until the smoking stops.

[0003] However, long-term high-temperature heating requires a lot of energy, which results in high power of electric heating devices and frequent charging. In addition, excessively high smoke temperature increases the difficulty of cooling the mouthpiece of low-temperature cigarettes. Generally, the heating of the heating element relies on heat transfer to transfer heat, and it is difficult for heat to reach the substrate area far away from the heating element, resulting in uneven heating of the substrate as a whole. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide a self-heating aerosol product, a method for preparing a self-heating cigarette, and a method for preparing a self-heating electronic cigarette. The self-heating aerosol product can reduce the working temperature and time of the heating element, and at the same time, the amount of smoke released can meet the suction requirements.

[0005] To achieve this object, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a self-heating aerosol product, which includes an aerosol product matrix and ozone oil added to the aerosol product matrix; 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.

[0006] Preferably, the ozone content in the ozone oil is 0.1-160 mg / g.

[0007] More preferably, the ozone content in the ozone oil is 20-100 mg / g.

[0008] Preferably, the oil agent of the ozone oil is selected from unsaturated fatty acids.

[0009] 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.

[0010] Preferably, the aerosol product matrix is ​​selected from low-temperature cigarette tobacco or electronic cigarette oil.

[0011] In a second aspect, the present invention provides a method for preparing a spontaneous low-temperature hot cigarette, comprising the following steps: The ozone oil is sprayed on the surface of low-temperature cigarette shreds and allowed to stand to prepare cigarettes.

[0012] Preferably, the mass ratio of the ozone oil to low-temperature cigarette tobacco is 1:1000-1:20.

[0013] Preferably, the standing time is 1 to 5 h.

[0014] In a third aspect, the present invention provides a method for preparing a self-heating electronic cigarette, comprising the following steps: Preferably, the mass ratio of the ozone oil to the electronic cigarette oil is 1:1000~1:20.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (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; (2) The ozone oil added in the present invention can stably release oxygen under heating, which is beneficial to the comfort of flue gas and increases the amount of flue gas; (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 far away from the heating element to release atomized smoke through their own heat; (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

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In view of the problems of high working temperature and uneven heating of the substrate in the atomized smoke products in the prior art, the present invention provides a self-heating aerosol product, which comprises an aerosol product substrate and ozone oil added to the aerosol product substrate. The aerosol product substrate is selected from low-temperature cigarette shreds or electronic cigarette oil, or other common aerosol substrates in the art.

[0018] In the present invention, the introduction of ozone in the ozone oil plays a key role in the self-heating effect of the aerosol product.

[0019] Ozone (O3) is also called superoxide. At room temperature, ozone has the smell of grass. At room temperature and pressure, it has poor stability and can decompose into oxygen by itself. Inhaling a small amount is beneficial to the human body, but inhaling too much is harmful to human health. Generally, the reaction formula of ozone is: 2O3→3O2+285 kJ.

[0020] It can be seen that the introduction of ozone not only brings sufficient oxygen, but its decomposition reaction can also generate heat.

[0021] However, ozone usually exists in the form of gas at room temperature and pressure, which is not convenient to introduce into the aerosol matrix. The present invention forms a stable molecular structure of ozone and oil (i.e., unsaturated fatty acid), i.e., ozone oil. Generally, ozone oil is stored in the dark at room temperature and pressure, and the half-life of ozone is three years. The half-life of ozone oil at 0°C can reach ten years. The higher the temperature, the faster the decomposition of ozone, and ozone can be decomposed at 270°C.

[0022] In the present invention, the unsaturated fatty acids can specifically be ω-9 series unsaturated fatty acids represented by oleic acid contained in tea oil, ω-6 series unsaturated fatty acids represented by linalool contained in vegetable oil, ω-3 series unsaturated fatty acids represented by EPA and DHA contained in fish oil, etc.

[0023] In the present invention, the content of ozone in the ozone oil is 0.1-160 mg / g, preferably 20-100 mg / g.

[0024] 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 on the basis of the amount of ozone.

[0025] The present invention not only facilitates the introduction of ozone components into the aerosol matrix by adding the above-mentioned ozone oil, but also can effectively realize self-heating by means of the decomposition of ozone, and can significantly reduce the working temperature of the heating element while increasing the smoke volume.

[0026] Exemplarily, the present invention provides a method for preparing a self-heating low-temperature cigarette, comprising the following steps: The ozone oil is sprayed on the surface of low-temperature cigarette shreds and allowed to stand to prepare cigarettes.

[0027] According to the present invention, ozone oil is sprayed on the surface of low-temperature cigarette shreds, and after standing, cigarettes are prepared. The ozone oil is as described in the above-mentioned related content, which will not be repeated here. The spraying can be carried out according to the method well known to those skilled in the art. It should be noted that the ozone oil should be sprayed evenly as much as possible during the spraying process.

[0028] 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.

[0029] After spraying, according to the present invention, it 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.

[0030] The present invention has no particular limitation on the source of the low-temperature cigarette shreds and the steps for preparing the low-temperature cigarettes, and the steps may be performed according to the contents known to those skilled in the art.

[0031] The present invention tests the obtained self-heating low-temperature cigarettes and finds that the smoke volume can still meet the smoking requirements when smoked using a low-temperature cigarette utensil with a heating temperature of 100°C.

[0032] Exemplarily, the present invention provides a method for preparing a self-heating electronic cigarette, comprising the following steps: The ozone oil is added to the electronic cigarette oil to prepare the electronic cigarette.

[0033] 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.

[0034] 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.

[0035] The present invention tests the obtained self-heating electronic cigarette and finds that the amount of smoke increases significantly when the electronic cigarette is smoked at a temperature of 150-200° C. The amount of smoke is still relatively large when the heating temperature of the electronic cigarette is lowered by 40-50° C.

[0036] It can be seen that the self-heating electronic cigarette and the self-heating low-temperature cigarette prepared by the preparation method of the present invention can not only achieve self-heating and reduce the working temperature of the heating device, but also meet the sensory smoking requirements of the user.

[0037] 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 common commercially available products.

[0038] Example 1

[0039] Ozone oil (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 a normal temperature working environment. After standing for three hours, low-temperature cigarettes are prepared according to the usual process.

[0040] Sensory smoking effect: When smoking with a low-temperature cigarette utensil with a heating temperature of 150°C, the smoke volume can still meet the smoking requirements.

[0041] Example 2

[0042] Ozone oil (solvent is 20-carbon 5-enoic acid (EPA)) with an ozone content of 50 mg / g was added into the electronic cigarette oil at a mass ratio of 2%, and the electronic cigarette was prepared according to the usual process.

[0043] Sensory tasting effect: The amount of smoke from the electronic cigarette is significantly larger than that of the electronic cigarette without ozone oil. When the heating temperature of the electronic cigarette is lowered by 40℃, the amount of smoke is still relatively large.

[0044] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those 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 will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
