Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of candles, and in particular to a paper wick with a drainage piece and an environmentally friendly candle using the paper wick. 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 birthday parties, religious festivals and other activities.
[0003] A candle typically consists of a container with a holding cavity, kerosene within the cavity, and a wick immersed in the kerosene. Kernel oil is primarily made from paraffin wax, with additives such as white oil, stearic acid, polyethylene, and fragrances added to create a variety of craft candles. Wicks can be made from a variety of materials, with cotton being a common choice. However, cotton wicks can be prone to incomplete combustion, emitting black smoke, and are also soft and prone to collapsing.
[0004] Wicks can be made of different materials. Cotton or wood chips are commonly used as wicks. Cotton wicks are prone to incomplete combustion, emitting black smoke, and are also soft and prone to falling over. Wood wicks are less stable and tend to self-extinguish. Paper wicks are also currently available on the market. Compared to cotton and wood wicks, paper wicks burn more completely and are less likely to emit black smoke. They also allow for a stronger aroma during candle burning, are less likely to fall over, and are less likely to self-extinguish.
[0005] However, some factors can affect the consistent and stable burning of paper wicks, causing the flame size to be unstable. For example, the fiber distribution and the degree of compression of some paper sheets can affect their oil absorption, resulting in an unstable flame size, carbonization, and the emission of black smoke during combustion, which can affect both health and the aesthetics of the product.
[0006] Therefore, continued improvement is needed. Summary of the Invention
[0007] The technical problem to be solved by the present invention is to provide a paper wick with a drainage piece that is conducive to continuous and stable combustion in response to the above technical status quo.
[0008] The second technical problem to be solved by the present invention is to provide an environmentally friendly candle.
[0009] The technical solution adopted by the present invention to solve the first technical problem is: a paper wick with a drainage member, characterized in that:
[0010] There are two paper sheets spaced apart from each other, and both of the paper sheets extend in the up-down direction;
[0011] A guide member is provided between the two paper sheets to form a guide channel, and the guide member guides the liquid fuel to diffuse along the combustion path of the paper sheets.
[0012] Preferably, the width of the drainage channel is 0.5-2.0 mm. The paper sheet and the drainage member are bonded together to form a single piece. The distance between the two paper sheets is equal to the width of the drainage channel. If the width is too wide, two flames may form, affecting the candle's burning effect.
[0013] Preferably, the drain member is one or more of paper, cotton fiber, hemp fiber, cotton and hemp blended rope, wood, and porous ceramic strips; and the drain member has an oil absorption rate greater than that of the paper sheet. The paper sheet is made of an environmentally friendly and degradable material (such as kraft paper), or ordinary paper with good absorbency.
[0014] To improve drainage, the first and / or second surfaces of the paper sheet are preferably provided with one or more oil-guiding grooves. The oil-guiding grooves on the first surface are spaced apart along the length of the paper sheet; the oil-guiding grooves on the second surface are arranged in a grid pattern or as straight strips extending along the length of the paper sheet, with the angle between the grid lines of the grid-like oil-guiding grooves and the width of the paper sheet being greater than 45°. Wax produced by burning candles can flow between the two paper sheets through the oil-guiding grooves. Furthermore, the oil-guiding grooves on the second surface can guide the wax upward and downward, improving combustion efficiency.
[0015] In order to optimize the combustion performance, preferably, the depth of the oil guide groove is 20-60 μm. When the depth of the oil guide groove is 20-60 μm, the candle has the best combustion performance, the flame is not easy to extinguish and the flame height is high.
[0016] For ease of manufacturing, preferably, the oil guide groove of the guide member is manufactured by a nanoimprinting process, which has high precision, low cost, and high production efficiency.
[0017] Preferably, the drainage members extend continuously or are arranged at intervals along the length direction of the paper sheet.
[0018] Preferably, the thickness of the upper end of a single paper sheet is 0.1-0.3 mm; the width of the upper end of the paper sheet is 0.6-2 mm.
[0019] In order to facilitate production and improve the efficiency of production and installation, preferably, the method for making the paper wick is:
[0020] ① Determine the material and specifications of the guide piece and the depth, width and position of the oil guide groove, and prepare the drawing;
[0021] ② Hot emboss the paper according to the drawing on the nanoimprint machine;
[0022] ③ A laser cutting machine is used to cut the paper sheet to obtain the required drainage piece, or to obtain paper including the drainage piece and the paper sheet;
[0023] ④ Manually fold the paper to form a paper wick, with the folding angle ≥ 90°, or manually or by hot pressing the laminating machine to bond the drainage piece to the paper sheet.
[0024] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: an environmentally friendly candle, characterized in that it includes a container with a accommodating cavity with an open top, kerosene located in the accommodating cavity, and a paper wick for the candle, wherein the paper wick is immersed in the kerosene through the open top; the proportion of vegetable wax in the kerosene is ≥80%.
[0025] Compared with the prior art, the advantages of the present invention are: a guide piece is provided to guide the wax oil to diffuse along the combustion path of the paper sheet, and also to guide the flow of wax oil between the two paper sheets, thereby optimizing the diffusion path of the wax oil after the candle burns, and avoiding the problem of flameout or smoking caused by uneven fuel supply during the combustion process; it helps the paper wick to burn continuously and stably, and the flame is not easy to extinguish, which is beneficial to reduce the requirements for the performance of the paper sheet material, and is also beneficial to increase the flame height; the paper wick of the present invention combines the advantages of paper and other materials, overcomes the defects that paper is easy to burn and ash and wood is not easy to burn, and is easy to produce and manufacture, simulates wooden wicks, burns fully, is not easy to shed ash, has a long flame, and is easy to shape; the proportion of plant wax in the environmentally friendly candle oil in the candle is ≥80%, and the oil uses renewable, biodegradable environmentally friendly plant oil materials, burns cleanly, has no black smoke, and has low energy consumption. Compared with the paraffin wax of traditional candles, the production and filling temperature is low, the energy consumption is low, it can be operated at low temperature, and is harmless to the human body.

[0033] In this patent, the paper sheet and the length direction of the paper sheet refer to the height direction of the wick, and the width direction of the paper sheet refers to the width direction of the wick.
[0034] Example 1
[0035] like Figure 1-2 FIG. 1 is a preferred embodiment of the present invention. A paper wick 300 with a drainage member 2 comprises a paper sheet 1 and a drainage member 2 .
[0036] There are two paper sheets 1 spaced apart from each other, and both paper sheets 1 extend in the up-down direction.
[0037] The guide member 2 is disposed between the two paper sheets 1 to form a guide channel. The guide member 2 guides the liquid fuel to diffuse along the combustion path of the paper sheets 1. The paper sheets 1 and the guide member 2 are bonded together to form a single piece. The oil absorption rate of the guide member 2 is greater than that of the paper sheets 1. The width of the guide channel is the same as the spacing between the two paper sheets 1. In this embodiment, the width of the guide channel is 0.5 mm. In other embodiments, the width of the guide channel is 0.5-2.0 mm. At this width, the candle with the paper wick 300 has better combustion performance. In this embodiment, the guide member 2 is a piece of paper, which is an environmentally friendly and degradable material (such as kraft paper) or ordinary paper with good adsorption properties. In other embodiments, the guide member 2 is one or more of paper, cotton fiber, hemp fiber, cotton and hemp blended rope, thin wood sheet, and porous ceramic strip. The drainage member 2 extends continuously along the length direction of the paper sheet 1 . In other embodiments, the drainage members 2 may be arranged at intervals along the length direction of the paper sheet 1 .
[0038] The method for making the paper wick is as follows:
[0039] ① Determine the material, specifications and dimensions of the drainage member 2 and the depth, width and position of the paper sheet 1, and prepare a drawing;
[0040] ② The laser cutting machine cuts the paper sheet material according to the drawing to obtain the drainage member 2, or obtains the paper including the drainage member 2 and the paper sheet 1;
[0041] ③ The paper is folded manually to form a paper wick, and the angle between the drainage piece 2 and the paper sheet 1 after folding is ≤90°, or the drainage piece 2 and the paper sheet 1 are bonded manually or by a hot pressing machine.
[0042] See also Figure 2An embodiment of the present invention further provides an environmentally friendly candle, which includes a container 100 having a accommodating cavity 101 with an open top, kerosene 200 located in the accommodating cavity 101, and the aforementioned paper wick 300 for the candle, wherein the paper wick 300 is immersed in the kerosene 200 through the open top.
[0043] Examples 2-4
[0044] The difference between Example 2-4 and Example 1 is that the width of the drainage channel is different.
[0045] Comparative Example 1
[0046] Comparative Example 1 differs from Example 1 in that the Comparative Example lacks a drain member 2, and the paper sheet 1 is composed of two laminated layers. As shown in Table 1, the presence of the drain member 2 results in a higher candle flame height and a lower self-extinguishing rate. A wider drain channel also results in a lower self-extinguishing rate.
[0047] Table 1 Parameters of paper wicks in Examples 1-4 and Comparative Example 1
[0048]
[0049] Example 5
[0050] like Figure 3 As shown, this embodiment differs from Example 1 in that one or more oil-conducting grooves 21 are provided on the paper sheet, spaced apart along the length of the paper sheet. In this embodiment, the depth of the oil-conducting grooves 21 is 20 μm and is fabricated using a nanoimprinting process. In other embodiments, the depth of the oil-conducting grooves 21 can be adjusted to 20-60 μm.
[0051] The method for making the paper wick is as follows:
[0052] ① Determine the material and size of the paper and the depth, width and position of the oil guide groove 21 to prepare a drawing;
[0053] ② Hot stamping the paper according to the drawing on a nano-imprinting machine to form the oil guide groove 21;
[0054] ③ The laser cutting machine cuts the paper to obtain the drainage member 2, or obtains the paper including the drainage member 2 and the paper sheet 1;
[0055] ④ Manually fold the paper to form a paper wick, and after folding, the angle between the drainage piece 2 and the paper sheet 1 is ≤90°, or manually or by a hot pressing laminating machine to bond the drainage piece 2 and the paper sheet 1.
[0056] Examples 6-16
[0057] As shown in Table 2, the difference between Examples 6-16 and Example 5 is that the width of the drainage channel and the depth of the oil guide groove 21 are different.
[0058] Table 2 Parameters of paper wicks of Examples 1-16
[0059]
[0060] Examples 17-24
[0061] The differences between Examples 17-24 and Example 1 are: the width of the drainage channel is different; and the drainage member 2 is made of cotton fiber and / or hemp fiber. The parameters of Examples 17-24 are shown in Table 3.
[0062] The method for making the paper wicks of Examples 17-24 is as follows: bonding the drainage member 2 and the paper sheet 1 manually or using a hot pressing laminating machine.
[0063] Comparative Examples 2-5
[0064] The difference between Comparative Examples 2-5 and Example 1 is that there is no guide member between the two paper sheets in Comparative Examples 2-5. As shown in Table 3, when the guide member 2 is present, the candle flame height is higher and the self-extinguishing rate is lower.
[0065] Table 3 Parameters of Examples 17-24 and Comparative Examples 2-5
[0066]
[0067] Examples 25-39
[0068] The parameters of Examples 25-39 are shown in Table 4. The difference between Examples 25-39 and Example 2 is that: there are two drainage members 2 spaced apart from each other, respectively designated as a first drainage member 22 and a second drainage member 23, wherein the first drainage member 22 is a paper sheet, and the second drainage member 23 is cotton fiber and / or hemp fiber; Figure 4 This is a schematic diagram of the structure of Example 25; the depth of the oil guide groove 21 and the material of the second guide member are shown in Table 4. It can be seen that the presence of the second guide member 23 increases the candle's flame height and reduces its self-extinguishing rate. In other embodiments, the first guide member 22 and the second guide member 23 can both be paper sheets. The oil guide groove 21 can be embossed on one or both sides of the first guide member 22 and the second guide member 23. Furthermore, the first guide member 22 and the second guide member 23 can be symmetrically arranged relative to the central axis of the paper sheet 1.
[0069] The method for making the paper wicks of Examples 25-30 is as follows:
[0070] ① Determine the material and specifications of the first guide member 22 and the depth, width and position of the oil guide groove 21, and prepare a drawing;
[0071] ② Hot-emboss the paper made of the first guide member 22 on a nano-imprint machine according to the drawing to form the oil guide groove 21;
[0072] ③ The laser cutting machine cuts the paper to obtain the first drainage member 22 or the paper including the first drainage member 22 and the paper sheet 1;
[0073] ④ Manually fold the paper to form the first drain piece 22 and the paper sheet 1, or manually or with a hot pressing machine to bond the first drain piece 22 and the paper sheet 1; then, manually or with a hot pressing machine to bond the second drain piece 23 and the paper sheet 1.
[0074] Table 4 Parameters of Examples 25-39 and Example 2
[0075]
[0076] Examples 40-43
[0077] The parameters of Examples 40-43 are shown in Table 5. The difference between Examples 40-43 and Example 1 is that: one or more oil guide grooves 21 are provided on both the first and second sides of the paper sheet. The oil guide grooves 21 on the first side are arranged at intervals along the length direction of the paper sheet to achieve drainage between the two paper sheets 1; the oil guide grooves 21 on the second side are straight strips extending along the length direction of the paper sheet (see Figure 5 ), or, in a grid-like form, such as Figure 6 As shown, the grid lines of the grid-like oil guide grooves 21 form an angle greater than 45° with the width of the paper sheet, thereby directing the melted wax upward and downward. Table 5 shows that double-sided embossing of the oil guide grooves 21 results in better candle burning performance, a lower self-extinguishing rate, and stable combustion compared to single-sided embossing. The paper wicks of Examples 31-34 were manufactured using the same method as Example 5.
