Description

Technical Field

[0001] The invention relates to the technical field of liquid candles, and in particular to lamp oil for liquid candles and the liquid candles. Background Art

[0002] Candles are a daily lighting tool. As a traditional lighting product, they have a long history of use and are often used in banquets, festivals and other activities.

[0003] Commonly used candles are solid candles. The fuel of solid candles is solid, mainly made of paraffin. The added auxiliary materials include white oil, stearic acid, polyethylene, flavors, etc., which can be made into craft candles of various shapes.

[0004] In addition, there are liquid candles. The fuel of liquid candles is liquid, which is also called lamp oil. The wick absorbs the lamp oil to the upper end of the wick, ignites the upper end of the wick and burns.

[0005] For example, the Chinese utility model patent "Artistic Colored Liquid Candles" with the authorization number CN2673871Y and the Chinese invention application "Liquid Candle System" with the publication number CN105593355A both disclose liquid candles. Another example is "A Liquid Candle" with the authorization number CN202415511U. The fuel of the liquid candle is any one of isoparaffins, normal paraffins, kerosene, heavy wax, light wax and white oil, but 1) these fuels are unsustainable and do not conform to the concept of green environmental protection; 2) the gasoline smell is heavy; 3) it is often not fully burned and is prone to black smoke; 4) the ingredients are not safe and healthy, and long-term use may be harmful to users.

[0006] There are also liquid candles that use alcohol substances such as ethanol as fuel, but 1) they are harmful if ingested; 2) the fuel is relatively thin, and the lamp oil is easily caused to fall due to gravity and is not easy to reach the top of the wick, thus affecting the ignition and the size of the flame; 3) the fuel has a low flash point and is flammable, generally belonging to a dangerous item, which is not safe and has high requirements for transportation and storage; 4) the smell is somewhat irritating. Summary of the invention

[0007] The first technical problem to be solved by the present invention is to provide a green, environmentally friendly, less gasoline odor, less likely to produce black smoke during combustion, and safe and healthy kerosene for liquid candles in view of the current status of the prior art.

[0008] The second technical problem to be solved by the present invention is to provide a safer lamp oil for liquid candles.

[0009] The third technical problem to be solved by the present invention is to provide a transparent and clear lamp oil for liquid candles.

[0010] The fourth technical problem to be solved by the present invention is to provide a liquid candle.

[0011] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is: a lamp oil for liquid candles, characterized in that it comprises the following components by volume:

[0012] 2-90 parts of vegetable oil;

[0013] 10 to 98 parts of a flammable solvent, wherein the viscosity of the flammable solvent is lower than that of the vegetable oil;

[0014] Solubilizer 0 to 3 parts.

[0015] Preferably, the vegetable oil comprises at least one of soybean oil, rapeseed oil, palm oil, corn oil, olive oil and peanut oil;

[0016] Or / and, the flammable solvent comprises at least one of dipropylene glycol methyl ether, isopropyl myristate, glyceryl caprylate, carbitol, isononyl isononanoate, and 3-methoxy-3-methyl-1-butanol;

[0017] Or / and, the solubilizer includes at least one of sorbitan polyether-30 and laureth-4.

[0018] In order to further solve the second technical problem of the present application, preferably, the flash point of the flammable solvent is greater than 60°C, or / and the flash point of the kerosene is greater than 60°C.

[0019] This way the flash point is higher and safer, and the requirements for transportation and storage are lower.

[0020] In order to increase the fragrance, the lamp oil also includes, by volume,

[0021] 0-10 parts of essence or essential oil.

[0022] When using essential oils, they have the following three functions: First, they increase the fragrance of liquid candles when they are burning; second, when the liquid candles are not burning, they can also be used as liquid fragrance volatile products, spreading the fragrance through rattan sticks, etc., or used as floating oil fragrance products; third, essential oils are oily, which is conducive to mutual integration with vegetable oils and flammable solvents, and lamp oil is not easy to stratify.

[0023] Preferably, the essential oil is at least one of rose oil, jasmine oil, rose oil and magnolia oil.

[0024] Preferably, the kerosene comprises the following components by volume:

[0025] The vegetable oil is soybean oil, accounting for 2 to 5 parts by volume;

[0026] The flammable solvent is isopropyl myristate, which accounts for 90 to 95 parts by volume.

[0027] The kerosene viscosity of this formula is preferably ≤10Pa.s.

[0028] Preferably, the kerosene comprises the following components by volume:

[0029] The vegetable oil is soybean oil, accounting for 40 to 60 parts by volume;

[0030] The flammable solvent is dipropylene glycol methyl ether, which accounts for 40 to 60 parts by volume.

[0031] The kerosene viscosity of this formula is preferably ≤18Pa.s.

[0032] To further solve the third technical problem of the present application, preferably, the kerosene comprises the following components by volume:

[0033] The vegetable oil is soybean oil, 2 to 5 parts;

[0034] The flammable solvents used are dipropylene glycol methyl ether and isopropyl myristate.

[0035] 85-90 parts of dipropylene glycol methyl ether;

[0036] 5-10 parts of isopropyl myristic acid.

[0037] By combining dipropylene glycol methyl ether, isopropyl myristate and soybean oil, the following advantages are achieved:

[0038] ① Lamp oil is harmless and highly safe, because soybean oil, dipropylene glycol methyl ether, and isopropyl myristate are all harmless ingredients. Liquid candles are harmless to inhale after lighting, and are also harmless to ingestion by mistake, so they are highly safe;

[0039] ② The lamp oil is easy to be absorbed by the wick, which is conducive to the ignition of the liquid candle. Although soybean oil itself is relatively viscous, after being diluted with dipropylene glycol methyl ether and isopropyl myristate, the overall consistency of the lamp oil is more appropriate, which is convenient for the wick to absorb upwards and the liquid candle to be ignited;

[0040] ③ Lamp oil has a high flash point, greater than 70°C, and is relatively safe. The flash point of dipropylene glycol methyl ether is relatively low, at around 70°C. After the action of soybean oil and isopropyl myristate, the flash point of lamp oil can be raised to above 70°C. In this way, lamp oil is not a flammable hazardous substance and is easy to transport and store.

[0041] ④ The smell of lamp oil is mild and not pungent. Dipropylene glycol methyl ether itself has a certain pungent smell and smells rather pungent, but isopropyl myristate is odorless, soybean oil is almost odorless, and the amount used is small. After the action of soybean oil and isopropyl myristate, the smell of lamp oil is mild and not pungent;

[0042] ⑤ Lamp oil is transparent and clear. Dipropylene glycol methyl ether has a certain hydrophilicity and can absorb moisture in the air, which may cause the lamp oil to be turbid and affect the appearance of the lamp oil. Soybean oil and isopropyl myristate are incompatible with water. This helps to isolate the lamp oil from external moisture to a certain extent, reduce water absorption, and help the lamp oil remain transparent and clear.

[0043] The technical solution adopted by the present invention to solve the fourth technical problem is: a liquid candle, characterized in that it includes the lamp oil for liquid candles as mentioned above, as well as a lamp tube and a wick; the lamp tube is used to accommodate the lamp oil and the wick.

[0044] The height of the lamp tube is less than or equal to 18 cm, the wick is made of glass fiber, and the viscosity of the lamp oil is ≤10 Pa.s;

[0045] Or, the height of the lamp tube is less than or equal to 8 cm, the wick is made of cotton or glass fiber, and the lamp oil viscosity is ≤18 Pa.s.

[0046] Different lamp oils are suitable for wicks of different materials.

[0047] Compared with the prior art, the advantages of the present invention are: 1. Vegetable oil is oil obtained from fruits, seeds and germs of plants. Plants are considered to be sustainable resources, so vegetable oil is sustainable and conforms to the concept of green environmental protection;

[0048] 2. It uses vegetable oil, which does not have the smell of gasoline and smells more comfortable;

[0049] 3. Vegetable oil is mainly composed of fat, which has sufficient oxygen supply, is conducive to full combustion, and is not easy to produce black smoke; while the components such as alkanes in the prior art are prone to incomplete combustion and easy to produce black smoke;

[0050] 4. The vegetable oil ingredients are safe and healthy and can be used for a long time;

[0051] 5. Vegetable oil is relatively viscous. Use flammable solvents to dilute the vegetable oil to reduce the viscosity. This way, the viscosity of the lamp oil is more appropriate and not too thick, making it easier to be absorbed by the wick.

[0052] 6. Adding a solubilizer will help the vegetable oil and the combustible solvent to blend together and prevent the kerosene oil from stratifying. BRIEF DESCRIPTION OF THE DRAWINGS
