Description

Technical Field

[0001] The utility model relates to the technology in the field of lighters, in particular to a lighter using a porous glass wick. Background Art

[0002] For traditional fuel lighters, it is usually necessary to place a wick in fuel for oil absorption to supply combustion. This kind of wick is generally made of pure cotton material or composed of cotton material wrapped with fiberglass material. After burning for a certain period of time, the upper burning part of the wick is prone to high-temperature carbonization, resulting in insufficient oil supply and inability to provide enough fuel for combustion, affecting the normal use of the product. To solve this problem, it is necessary to cut off the carbonized part of the wick or replace it with a new one, and operations such as trimming the wick and replacing the wick are often required. Moreover, the material texture of such wicks is relatively soft, and when installing or replacing the wick, auxiliary tools must be used to complete the installation of the wick, which is inconvenient to operate. In addition, due to the material limitation of traditional wicks (wick), transparency cannot be achieved. When forming products, especially when making transparent lighters, it is not beautiful and difficult to attract consumers. In addition, when traditional wicks need a large liquid absorption amount, only the outer diameter of the wick can be thickened, and there are few other operable means. The fuel tank opening of the corresponding product must also be increased, which brings inconvenience to the product structure design.

[0003] Therefore, the existing kerosene lighters should be improved to solve the above problems. Content of the Utility Model

[0004] In view of this, in view of the deficiencies existing in the prior art, the main purpose of the present utility model is to provide a lighter using a porous glass wick. The lighter is formed by installing a wick made of quartz glass or borosilicate glass on a base. The wick has a plurality of micron-sized pores, and has high temperature resistance and good durability. The pore diameter, porosity, outer diameter, length, etc. of the wick can be designed according to actual application needs to meet the requirements of various fuel delivery flows, and the application range is wide.

[0026] As shown in the present utility model Figures 1 to 6 A lighter using a porous glass wick, comprising a base 10 and an upper cover 20 hinged to the base 10, wherein:

[0027] A fuel tank 11 for containing liquid fuel is provided in the base 10, a wick 12 is provided in the fuel tank 11, a through hole 13 for the wick 12 to extend out of the fuel tank 11 is provided at the upper end of the base 10 corresponding to the wick 12, the upper end of the wick 12 extends out of the upper part of the base 10 through the through hole 13, the wick 12 includes a strip-shaped substrate 121 made of glass, and a plurality of micron-level channels 122 are densely arranged in a penetrating manner along the extending direction of the substrate 121, and the fuel in the fuel tank 11 rises to the upper end of the wick 12 through the channels 122; an ignition mechanism 30 is provided at the upper end of the base 10, and the ignition mechanism 30 is located beside the upper end of the wick 12.

[0028] The wick 12 is vertically inserted into the fuel tank 11 through the through hole 13, and a holding member 14 for fixing the upper end of the wick 12 to keep it in a vertical state all the time is arranged outside the through hole 13. A windproof cover 15 is arranged on the upper part of the base 10 corresponding to the through hole 13. The windproof cover 15 surrounds the outside of the upper end of the wick 12, and ventilation holes 151 are arranged on the windproof cover 15 to avoid being interfered by external air flow when the lighter is ignited, and at the same time, sufficient oxygen supply can be ensured.

[0029] The ignition mechanism 30 includes a fire wheel 31, a flint 32 and an elastic support rod 33. The fire wheel 31 is rotatably installed on the side part of the windproof cover 15. The elastic support rod 33 (in the form of a combination of a spring and a support rod) is vertically installed in the base 10. The flint 32 is installed at the top of the elastic support rod 33 and abuts against the lower end of the fire wheel 31. Quickly turning the fire wheel 31 can generate sparks by rubbing the flint 32 to ignite the wick 12.

[0030] A ventilation device 16 for communicating with the fuel tank 11 to balance the internal and external pressures of the fuel tank 11 is arranged on the base 10. The ventilation device 16 includes a gas hole 161 and a glass microporous plug 162 installed in the gas hole 161. The glass microporous plug 162 includes a matrix 121 made of glass material. A plurality of micron-sized pores 122 are densely arranged in a penetrating manner along the extending direction of the matrix 121, and an oil-repellent treatment is carried out to make the glass microporous plug 162 have the characteristic of repelling oil. The aperture 123 of the pores 122 of the glass microporous plug 162 is 1μm - 4μm. The design of the micron-sized pores 122 on the glass microporous plug 162 can satisfy the balance of the internal and external pressures of the fuel tank 11 and avoid the flame jumping caused by uneven internal and external air pressures. At the same time, the pores 122 are tiny and the thickness of the glass microporous plug 162 is very thin, which can prevent the liquid fuel in the fuel tank 11 from splashing out. The pore structure 122 on the glass microporous plug 162 is the same as the pore structure 122 on the wick 12, only the aperture 123 and the length 124 are different, and the specific dimensions are set according to actual needs.

[0031] The wick 12 includes a strip-shaped matrix 121 made of quartz glass or borosilicate glass material. A plurality of micron-sized pores 122 are densely arranged in a penetrating manner along the extending direction of the matrix 121. The plurality of pores 122 are closely distributed on the cross-section of the matrix 121. The shape of the pores 122 is circular or other shapes, such as diamond-shaped, square-shaped, etc., and preferably circular.

[0032] The matrix 121 and its internal through pipe are both extended in a non-curved straight line manner, and the pores 122 are straight through holes 13 extending in a straight line.

[0033] Both the substrate 121 and the channels 122 extend in a straight line without curvature. The channels 122 are formed by straight-line extension in the straight through-hole 13 of the substrate 121. Setting both the substrate 121 and the channels 122 to be straight-line simplifies production and processing. The straight-line extension method enables mass production and improves production efficiency. On the other hand, the straight-line can reduce the obstruction of the pore wall when the fuel is transported in the channels 122, reduce the friction between the fuel and the pore wall, make the fuel transportation smoother, and improve the fuel transportation efficiency.

[0034] The transmission principle of the oil wick 12 mainly adopts the physical capillary phenomenon. The capillary phenomenon occurs in some capillaries with a linear dimension small enough to be comparable to the curvature radius of the fuel meniscus. The entire fuel surface in the capillary will become curved, and the interaction between liquid and solid molecules can extend to the entire fuel. When the oil wick 12 is inserted into the fuel, within a certain period of time, the fuel will continuously transport the fuel from bottom to top to the top of the substrate 121 along multiple micron-sized channels 122 in the transmission material.

[0035] The aperture 123 of the channels 122 is 1μm - 300μm, and can be specifically adjusted according to the characteristics of the fuel to be transported, such as density, viscosity, wettability, etc. If the viscosity of the fuel to be transported is small, the aperture 123 of the channels 122 can be designed to be relatively small; if the viscosity of the fuel to be transported is large, the aperture 123 of the channels 122 can be designed to be relatively large.

[0036] The porosity ratio of the channels 122 in the cross-section of the substrate 121 is 0.1% - 85%. The porosity is the ratio of the sum of the areas of the channels 122 to the cross-sectional area of the material. A higher porosity can increase the transmission flow rate of the transmission material within a certain period of time. When a larger transmission flow rate is required, the porosity can be increased to increase the area of the channels 122 in the cross-section of the substrate 121; when a smaller transmission flow rate is required, the porosity can be decreased to reduce the area of the channels 122 in the cross-section of the substrate 121. The size of the porosity ratio can be set according to the required liquid outflow rate within a certain period of time, with high flexibility.

[0037] The overall shape of the substrate 121 is cylindrical or cubic. The specific shape of the substrate 121 can be designed according to the corresponding application scenario, but its length 124 must be greater than its cross-sectional diameter or width to ensure that the transmission material is in a long strip shape.

[0038] The outer diameter of the substrate 121 is 0.5mm - 10mm, and the outer diameter parameter of the substrate 121 can be set according to the specific product space. The length 124 of the substrate 121 is 15mm - 200mm, and the specific length 124 can be set according to the size of the actual application product.

[0039] The wick 12 is made of hard glass and is transparent. After the liquid fuel enters the wick 12, it can be shown through the wick 12; and the wick 12 does not need to be trimmed and can be used for a long time.

[0040] The wick 12 in this application is mainly applied to lighter products using kerosene fuel. Of course, in addition to the above-listed products, the wick 12 can also be applied to other fields that require fuel transportation; the fuel transported by the wick 12 can be kerosene, ghee, alcohol, etc.

[0041] Using the glass wick 12 with multiple micron-sized channels 122 as the fuel transportation medium, it has the following advantages compared to the traditional cotton wick 12:

[0042] First, the wick 12 is made of quartz glass or borosilicate glass (preferably quartz) and has the characteristic of high temperature resistance, can be directly ignited, and has a wide range of applications;

[0043] Second, due to its material properties, the wick 12 has good durability and a long service life. It does not need to cut off the carbonized part like the traditional wick 12 after being used for a period of time (the upper burning part is carbonized, affecting the oil absorption effect) to be used normally, which is more worry-free and labor-saving;

[0044] Third, the aperture 123, the number of holes, the porosity, and the length 124 of the multiple micron-sized channels 122 of the wick 12 can all be designed according to actual application requirements to meet the adjustment requirements of the transmission flow rate within a fixed accommodation space and a fixed time, can adapt to different flow transmissions, has a wide range of applications, and is flexible in operation. While for the traditional wick 12, to increase the absorption and transmission flow rate of the oil liquid, it is necessary to increase the volume or increase the material density, which will result in being unable to be used within the original accommodation space, and it is necessary to simultaneously expand the opening of the fuel tank 11 to adapt to it, and the operation is inconvenient.

[0045] Fourth, the wick 12 is designed in a straight line, and the multiple straight through holes 13 in the form of micron-sized channels 122 inside make the fuel transportation smoother. After the wick 12 is placed in the fuel, the fuel can quickly reach the top from the bottom, with less transmission delay time, high transmission efficiency, and fast response speed, meeting the immediate needs of users;

[0046] Fifth, the wick 12 has a hard structure. When in use, it only needs to be inserted into the fuel accommodation cavity. It is less stained, does not require tool assistance, the operation process is fast, and the installation and replacement are convenient. While the traditional wick 12 is a cotton flexible structure, and during installation and replacement, tools must be used for operation, and it is easy to be stained with more stains, and the operation is cumbersome and inconvenient.

[0047] Sixth, when the fuel in the fuel lamp is transparent and enters the wick 12, the entire wick 12 is also transparent. While the traditional cotton or glass fiber wick 12 is opaque.

[0048] The design focus of the present utility model lies in that a lighter is formed by installing an oil wick made of quartz glass or borosilicate glass in a base. The oil wick has multiple micron-level pores and has high temperature resistance and good durability. According to actual application needs, the pore diameter, porosity, number of pores, and length of the oil wick can be designed to meet the requirements of various fuel delivery flows, with a wide range of applications. At the same time, the straight-through hole design has high delivery efficiency, and the hard transparent material manufacturing provides convenience for the installation and replacement of materials.

[0049] The above is only a preferred embodiment of the present utility model and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
