Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and in particular to an e-liquid and its preparation method. Background Technology

[0002] Electronic cigarettes, also known as virtual cigarettes, vaporizers, or aerosol generators, primarily work by heating e-liquid stored inside the e-cigarette to produce an aerosol for the user to inhale. E-liquid typically contains nicotine salts, and the resulting aerosol contains nicotine but does not contain harmful substances such as tar or carbon monoxide, thus providing users with a healthy alternative to traditional cigarettes.

[0003] Existing e-cigarettes are generally only used as a substitute for cigarettes and do not offer any additional functions, such as preventing motion sickness, seasickness, or airsickness. Motion sickness, seasickness, and airsickness all fall under the category of kinetosis, caused by any form of acceleration (or deceleration) such as bumps, swaying, and rotation produced when a car, ship, or airplane is in motion, stimulating the vestibular nerve. Symptoms are usually accompanied by dizziness, cold sweats, abdominal discomfort, nausea, and vomiting. Nowadays, with increasingly convenient transportation, people use airplanes, cars, and ships more and more frequently, and kinetosis causes great inconvenience to travel. Currently, commonly used medications for motion sickness are all Western medicines, which, in addition to their short duration of treatment, also have significant side effects, most commonly drowsiness, dizziness, and general weakness, and are unsuitable for people with poor gastrointestinal function. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this invention is to provide an e-liquid and its preparation method to solve the problem that electronic cigarettes cannot prevent motion sickness in the existing technology.

Attached Figure Description

[0025] Figure 1 This is a flowchart of the preparation method of e-liquid in this invention. Detailed Implementation

[0026] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation methods, structures, features, and effects of the e-liquid and its preparation method according to the present invention:

[0027] The present invention provides an e-liquid comprising a base e-liquid and an anti-motion sickness substance mixed together. The base e-liquid is used to atomize and generate smoke, and the anti-motion sickness substance is atomized together with the base e-liquid and used to prevent or alleviate motion sickness.

[0028] This application mixes anti-motion sickness substances into the e-liquid base liquid to form an e-liquid that can prevent or alleviate motion sickness. When a user inhales the e-cigarette, the e-liquid atomizes to produce vapor, and the anti-motion sickness substances are atomized along with the e-liquid base liquid and inhaled by the user, thereby preventing or alleviating the user's motion sickness. This achieves the goal of effectively preventing or alleviating motion sickness by inhaling e-cigarettes.

[0029] In this embodiment, the e-liquid base includes nicotine salts, propylene glycol, and glycerin. The addition of nicotine salts provides a stimulating and invigorating effect while also offering a smoother taste. Specifically, by weight, the nicotine salts comprise 2-7 parts, the propylene glycol 1-30 parts, and the glycerin 30-50 parts.

[0030] Furthermore, the e-liquid base also includes at least one of a sweetener and a cooling agent. Adding sweeteners and cooling agents improves the sweetness of the flavor and the cooling sensation in the mouth and nose, making the e-liquid more pleasant to drink. Specifically, by weight, the sweetener comprises 1-2 parts, and the cooling agent comprises 3-10 parts. Sweeteners are food additives that impart a sweet taste to soft drinks. Sweeteners can be classified into two categories based on nutritional value: nutritional sweeteners and non-nutritive sweeteners; based on their sweetness level: low-sweetness sweeteners and high-sweetness sweeteners; and based on their source: natural sweeteners and synthetic sweeteners. Natural sweeteners include stevia, licorice, disodium glycyrrhizate, tripotassium glycyrrhizate, and trisodium glycyrrhizate; synthetic sweeteners include saccharin, sodium saccharin, sodium cyclohexylsulfamate, and alitane, asparagine methyl ester. Cooling agents are a general term for all chemical substances that produce a cooling effect but are not very medicinal. The most common cooling agent is menthol (especially L-menthol), but due to its strong odor and strong irritation to the skin, mucous membranes and eyes, it should not be used in large quantities.

[0031] In this embodiment, the anti-motion sickness substance includes at least one of Zanthoxylum nitidum extract, Nardostachys jatamansi extract, and Eupatorium fortunei extract. Adding Zanthoxylum nitidum extract not only contributes to the aroma of the atomized liquid but also provides a cooling sensation, which can refresh the mind and prevent or alleviate motion sickness. Adding Nardostachys jatamansi extract can have a calming, analgesic, and stomach-strengthening effect, thus alleviating motion sickness. Adding Eupatorium fortunei extract is used to alleviate symptoms such as damp-heat retention, sweet and greasy taste in the mouth with excessive salivation, fever, headache, chest tightness, and indigestion. The proportions, by weight, are 1-3 parts Zanthoxylum nitidum extract, 2-10 parts Nardostachys jatamansi extract, and 2-10 parts Eupatorium fortunei extract. Of course, in other embodiments, the anti-motion sickness substance can also be other drugs that can effectively prevent or alleviate motion sickness, preferably plant extracts, to facilitate atomization along with the e-liquid base.

[0032] In this embodiment, the e-liquid also includes flavorings, including at least one of citronellal, citral, naringin, peppermint oil, and menthol. Adding citronellal, citral, or naringin can adjust the pungent taste of the plant extracts (Zanthoxylum nitidum extract, Nardostachys jatamansi extract, and Eupatorium fortunei extract), and can also prevent nausea and vomiting, resulting in a refreshing and pleasant effect. Adding peppermint oil or menthol can synergistically enhance the effect of Zanthoxylum nitidum extract, suppressing the hot flashes associated with motion sickness and preventing or alleviating kinesthesia. Specifically, by weight, the amounts are 1-3 parts citronellal, 2-12 parts citral, 1-3 parts naringin, 1-3 parts peppermint oil, and 1-3 parts menthol.

[0033] Understandably, depending on the actual production volume of e-liquid, each portion mentioned above, based on weight, can be 1 mg, 1 g, or 1 kg, etc.

[0034] Figure 1 This is a flowchart illustrating the preparation method of e-liquid in this invention. For example... Figure 1 As shown, this application also provides a method for preparing e-liquid, the method being used to prepare the e-liquid as described above. The preparation method includes:

[0035] Step S1: Provide an anti-motion sickness substance. This anti-motion sickness substance includes at least one of Zanthoxylum nitidum extract, Nardostachys jatamansi extract, and Eupatorium fortunei extract. Adding Zanthoxylum nitidum extract not only contributes to the aroma of the atomized liquid but also provides a cooling sensation, which can refresh the mind and prevent or alleviate motion sickness. Adding Nardostachys jatamansi extract can have a calming, analgesic, and stomach-strengthening effect, thus alleviating motion sickness. Adding Eupatorium fortunei extract is used to alleviate symptoms such as damp-heat retention, sweet and greasy taste in the mouth with excessive salivation, fever, headache, chest tightness, and indigestion. The amounts of Zanthoxylum nitidum extract, Nardostachys jatamansi extract, and Eupatorium fortunei extract are 1-3 parts by weight. However, in other embodiments, the anti-motion sickness substance can also be other drugs that can effectively prevent or alleviate motion sickness, preferably plant extracts, to facilitate atomization along with the e-liquid base.

[0036] Specifically, the preparation method of Zanthoxylum nitidum extract includes: pulverizing Zanthoxylum nitidum to 80-120 mesh, and subjecting the pulverized raw materials to supercritical carbon dioxide extraction to obtain supercritical carbon dioxide extract of Zanthoxylum nitidum, i.e. Zanthoxylum nitidum extract.

[0037] The preparation method of spikenard extract includes: pulverizing spikenard to 80-120 mesh, and subjecting the pulverized raw material to supercritical carbon dioxide extraction to obtain supercritical carbon dioxide extract of spikenard, i.e. spikenard extract.

[0038] The preparation method of Eupatorium fortunei extract includes: pulverizing Eupatorium fortunei to 80-120 mesh, and then subjecting the pulverized raw materials to supercritical carbon dioxide extraction to obtain supercritical carbon dioxide extract of Eupatorium fortunei, i.e., Eupatorium fortunei extract.

[0039] By weight, the raw materials are 4-6 parts of Zanthoxylum nitidum and 4-12 parts of Nardostachys jatamansi and Eupatorium fortunei.

[0040] Step S2: Provide a flavoring agent by mixing the anti-motion sickness substance with the flavoring agent to form a flavor composition. The flavoring agent includes at least one of sweet orange aldehyde, citral, naringin, peppermint oil, and menthol. Adding sweet orange aldehyde, citral, or naringin can modulate the pungent taste of the plant extracts (Zanthoxylum nitidum extract, Nardostachys jatamansi extract, Eupatorium fortunei extract), and can also prevent nausea and vomiting, providing a refreshing and pleasant effect. Adding peppermint oil or menthol can synergistically enhance the effect of Zanthoxylum nitidum extract to invigorate the mind, suppress the hot flashes associated with motion sickness, and prevent or alleviate motion sickness. The composition, by weight, is 1-3 parts sweet orange aldehyde, 2-12 parts citral, 1-3 parts naringin, 1-3 parts peppermint oil, and 1-3 parts menthol.

[0041] Step S3: Provide the e-liquid base. Mix and stir the above flavor combination with the e-liquid base. For example, the volatile e-liquid can be stirred evenly on a magnetic stirrer to obtain an e-liquid with anti-motion sickness properties. The e-liquid base includes nicotine salts, propylene glycol, and glycerin. By adding nicotine salts, a refreshing and stimulating sensation can be achieved while maintaining a smooth taste. Of course, the e-liquid base also includes at least one of sweeteners and cooling agents. By adding sweeteners and cooling agents, the sweetness of the flavor and the cooling sensation in the mouth and nose are improved, making the taste of the vaporized liquid more comfortable. Specifically, by weight, the nicotine salts are 2-7 parts, the propylene glycol is 1-30 parts, the glycerin is 30-50 parts, the sweetener is 1-2 parts, and the cooling agent is 3-10 parts.

[0042] Of course, in other embodiments, when there is no flavoring in the e-liquid, the e-liquid base liquid and the anti-motion sickness substance can be directly mixed and stirred.
