Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be described below with reference to the accompanying drawings.

Any embodiment or design described herein as "exemplary," "such as" or "for example" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary," "such as" or "for example," etc., is intended to present related concepts in a concrete fashion.

Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating an indicated technical feature. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.

To solve one of the technical problems in the related art, according to one embodiment of the present utility model, there is provided a lighting device, including a support portion and a lighting portion, wherein the support portion includes a heat transfer unit for contacting a combustible substance and a buoy unit for providing buoyancy to the support portion, and the heat transfer unit is located below the buoy unit, and the lighting portion includes an outer tube unit for transferring heat to the heat transfer unit and a plurality of wires accommodated in the outer tube unit.

Specifically, as shown in fig. 1, the ignition device of the present embodiment includes a support portion 10 and an ignition portion 20. The ignition device may be placed in a container (not shown in fig. 1), for example, open upward, which contains a combustible substance, which may include, but is not limited to, wax or fuel. It will be appreciated that when the container contains wax, the wax is typically in a solid state in the unused state.

Referring to fig. 1, the support 10 may further include a heat transfer unit 11 and a float unit 12. Wherein the heat transfer unit 11 is adapted to be in contact with the combustible substance in the aforesaid container, so that when the heat transfer unit 11 is heated, it is capable of transferring heat to the combustible substance. This is particularly useful when the combustible substance is still in a solid state in the unused state, helping to melt the solid combustible substance into a liquid, facilitating subsequent ignition or combustion.

Also, the float unit 12 may be used to provide buoyancy to the entire support 10 so that the entire support 10 floats like a float in the aforementioned combustible material when in a liquid state. In order to enable the heat transfer unit 11 to be in sufficient contact with and transfer heat from the combustible material, and also to facilitate subsequent control and adjustment of the buoyancy provided by the float unit 12, the heat transfer unit 11 may be positioned below the float unit 12. Given that the heat transfer unit 11 is typically heavy and the float unit 12 is typically light and heavy, and that it is typically non-metallic, this arrangement is also advantageous to maintain stability throughout the support 10 and even throughout the ignition device.

The heat transfer unit 11 may be made of a metal material, preferably a known metal material having a good heat transfer property, and can be ensured to have a good heat transfer property. In one example, the heat transfer unit 11 is preferably a metal plate-like member. This has a large heat conduction area and also provides a good stability when the entire support 10 floats in the combustible substance.

The float unit 12 may be made of a non-metallic material, preferably of a known non-metallic material having a low specific gravity and being resistant to high temperatures and combustion, which ensures that it provides sufficient buoyancy without deformation or even combustion due to the heat that may be conducted by the heat transfer unit 11. In one example, the float unit 12 is preferably a non-metallic plate-like member. This helps to increase buoyancy and also provides better stability when the entire support 10 floats in the combustible substance. When the heat transfer unit 11 is a plate-like member, the float unit 12 is also of a plate-like member structure, which facilitates the assembly between the two members, and can be coordinated and matched as a whole to form a neat and uniform appearance structure.

In one embodiment of the present utility model, when both the heat transfer unit 11 and the float unit 12 are in the form of plate-like members, both may be rectangular parallelepiped, having the same length and width so that both form a neat and uniform appearance structure, while the thickness of the metal plate-like member is smaller than that of the non-metal plate-like member so that the latter can provide a sufficiently large buoyancy.

In another embodiment of the present utility model, the heat transfer unit 11 is a metal plate-like member, the float unit 12 is a non-metal plate-like member, the metal plate-like member is located below the non-metal plate-like member, and an upper surface of the metal plate-like member is in direct contact with a lower surface of the non-metal plate-like member. Thereby, the assembly between the two is facilitated, and the structure of the entire support portion 10 is also relatively firm and compact.

In another embodiment of the present utility model, the heat transfer unit 11 is a metal plate-like member, and the float unit 12 is a non-metal plate-like member, the metal plate-like member is located below the non-metal plate-like member, and the upper surface of the metal plate-like member is not in direct contact with the lower surface of the non-metal plate-like member. Thereby, it is avoided that the metal plate-like member directly conducts heat to the non-metal plate-like member, thereby avoiding deformation or even burning of the non-metal plate-like member. In one example, a first spacer structure is provided between the upper surface of the sheet metal piece and the lower surface of the non-sheet metal piece. The first spacing structure may be formed of a known material having poor heat transfer characteristics so as to enhance the stability of the connection between the heat transfer unit 11 and the float unit 12 while also minimizing heat transfer therebetween.

Returning to fig. 1, the pilot portion 20 may further include an outer tube unit 21 and a wire 22. The outer tube unit 21 is used to transfer heat to the heat transfer unit 11 upon ignition or combustion. The outer tube unit 21 may be made of a known nonflammable, high temperature resistant material, which may have good heat transfer performance. The outer tube unit 21 may have a hollow tubular structure, and several wires 22 may be accommodated in the tubular structure of the outer tube unit 21. The wire 22 may be made of a known nonflammable, high temperature resistant material having a wire-like structure.

According to one embodiment of the utility model, the outer tube unit 21 may be a metal tubular member, the buoy unit 12 may be provided with a first through hole 13, and the heat transfer unit 11 may be provided with a second through hole 14, such that the outer tube unit 21 may pass through the first through hole 13 and the second through hole 14. In one example, the outer surface of the metallic tubular member is in direct contact with the inner wall surface of the second through hole 14 by a tight fit. Thereby, the outer tube unit 21 can be firmly connected with the heat transfer unit 11, and the outer tube unit 21 can sufficiently conduct heat to the heat transfer unit 11. The lowermost end of the outer tube unit 21 may protrude a small portion from the lower surface of the heat transfer unit 11 or may be flush with the lower surface of the heat transfer unit 11.

In another example, the outer surface of the metal tubular member of the outer tube unit 21 may not be in direct contact with the inner wall surface of the first through hole 13, thereby avoiding direct conduction of heat from the outer tube unit 21 to the float unit 12. In this case, a second spacing structure may be provided between the outer surface of the outer tube unit 21 and the inner wall surface of the first through hole 13, and may be made of a known material having poor heat conduction properties, while the outer tube unit 21 is more stably supported by the float unit 12, and heat conduction therebetween is also insulated as much as possible.

In one embodiment of the utility model, the wire 22 has an outer diameter of between 0.1 and 0.3 mm, which fills the hollow structure of the outer tube unit 21 as much as possible, essentially functioning as a wick. In one example, the wire 22 may have a hollow structure so that a combustible substance in a liquid state may also be contained therein, enhancing the capillary effect of the outer tube unit 21 when the entire ignition device is ignited. At this time, the outer diameter of the wire 22 may be between 0.1 and 0.3 mm, and the inner diameter may be between 0.05 and 0.2 mm.

In another embodiment of the utility model, the outer tube unit 21 is a metal tubular member having a diameter to height ratio of between 1:50 and 1:150, so that the capillary effect of the metal tubular member upon ignition of the entire ignition device can be effectively utilized and ensured.

In use, the ignition device of the present utility model, the outer tube unit 21 and/or the wires 22 contained therein may be first impregnated or wrapped with the combustible substance, or they may be first impregnated or wrapped with other known combustible substances, such as white phosphorus or the like, in preparation for ignition. In addition, in the case where the combustible substance is initially in a solid state, the ignition may also be achieved by first heating the outer tube unit 21 and/or the wires 22 contained therein, and then melting and vaporizing the solid combustible substance contacted by the heat transfer unit 11. After ignition, by sucking the combustible substance in liquid state to the tip of the outer tube unit 21 by capillary effect of the outer tube unit 21 and/or the wire 22 accommodated therein, the combustible substance can be kept in a combustion state all the time. In this case, the ignition device may float like a float in the combustible substance in liquid form inside the container.

According to the technical scheme of the utility model, the ignition device of the lighting equipment does not adopt the traditional cotton thread as the core, so that the ignition device is safer and more environment-friendly, and the waste of combustible substances can be avoided. In addition, the ignition device has novel shape, unique structure and wider application.

In this specification, each embodiment is described in a progressive manner, and identical and similar parts of each embodiment are all referred to each other, and each embodiment mainly describes differences from other embodiments.

The embodiments of the present utility model described above do not limit the scope of the present utility model. Any modifications, equivalent substitutions and improvements made within the principle of the present utility model should be included in the protection scope of the present utility model.
