Description

Technical Field

[0001] The utility model relates to a gas ignition device, in particular to a ignition device for a gas lighter. Background Art

[0002] In general, gas lighters can be divided into two categories from the perspective of function: open flame lighters and windproof lighters. Open flame lighters are gas that burns directly in the air. Its disadvantage is that the flame is small and easy to extinguish, but its advantage is simple structure and low cost. The disadvantage of existing windproof lighters is that the structure is complex and the cost is high, but the advantage is that the flame is not easily extinguished by the wind. Generally, consumers usually choose windproof lighters as their first choice, but the windproof lighters on the market are difficult to ignite tobacco, such as cigars, and it will be found that it is not easy to ignite with ordinary windproof lighters. Therefore, multi-flame windproof lighters are produced, which can produce multiple flames, but their cost is relatively high and the structure is relatively complex. Open flame lighters are easy to be blown out. In order to make them have a certain degree of windproofness, some manufacturers will use windproof sleeves around the top of the fire outlet on the shell. First, the windproof sleeve is easy to burn the user on the periphery of the flame. Secondly, the windproof sleeve increases the cost and reduces the aesthetics of the lighter. At the same time, the windproof sleeve is easy to further reduce the flame. Summary of the invention

[0003] The utility model provides a gas fire-generating device which is safe, low-cost and can produce a large flame.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a large flame gas ignition device, which is installed in the air outlet of the shell, and is also provided with an air storage box, an air outlet valve placed on the air storage box, an air control device for controlling the action of the air outlet valve, and a spark generating device arranged near the air outlet. The air outlet valve is connected to the ignition device through an air pipe, and includes a base body connected to the end of the air pipe and in a tubular shape with a central through hole. The top section of the base body is provided with a plurality of air expansion areas, and a plurality of air expansion holes penetrating the tube wall of the base body are opened in the air expansion area, and the plurality of air expansion holes are arranged along the length direction of the base body in the air expansion area.

[0005] As an improvement: a number of air expansion zones are arranged asymmetrically on the cross section of the tube wall, and a plurality of air expansion holes in the air expansion zone along the length direction of the base are connected to form a long groove-shaped air expansion groove, that is, the air expansion groove extends upward from the top section of the base to the opening of the base, and wind-blocking prism walls are formed between the air expansion grooves. The air expansion grooves at the left-right symmetrical positions on the cross section of the tube wall correspond to wind-blocking prism walls, thereby forming a laterally non-intersecting wind-blocking structure.

[0006] As an improvement: one or several ring members are sleeved on the top section of the base body near the opening position, and the peripheral wall of the ring member has a large number of micro pores penetrating the peripheral wall.

[0007] As an improvement: an ignition piece corresponding to the spark generating device is wound around the top section of the base, and the ignition piece at least partially passes through the gas expansion zone on the base.

[0008] As an improvement: the ignition piece is a spring with a pitch.

[0009] As an improvement: the free top of the substrate with the gas expansion zone is exposed at the gas outlet position, that is, the gas expansion zone is partially exposed at the gas outlet.

[0010] As an improvement: the multiple expansion holes in the expansion zone are not connected, and the expansion zones are arranged without gaps in the circumferential direction, that is, a large number of expansion holes are arranged on the top section of the base to form a top expansion section.

[0011] As an improvement: the multiple air expansion holes in the air expansion zone are not connected to each other, and the multiple air expansion zones are arranged with intervals in the circumferential direction.

[0012] The utility model provides the following beneficial effects: since the tube wall of the top section of the substrate is not closed, the fuel gas is not only released outward from the top of the substrate, but also diffuses outward from the top section gas expansion holes to mix with the air. After being ignited by the spark, an upward flame is formed from the gas expansion area, and the flame forms a thick root of the flame or a fire core around the gas expansion area, and the fire core is not completely exposed outside the fire outlet, and has a certain windproof property. The structure of the ignition device greatly improves the amount of gas fuel released and the mixing degree and mixing speed of the gas fuel and air, forming a thick root and a large flame, and the flame is stable. The gas expansion holes arranged along the length direction of the substrate can lengthen the length of the fire core, further increase the size of the flame, and make it difficult to blow out. At the same time, the ignition device has a simple structure, is easy to implement, low cost, safe, and has a certain versatility, that is, it can also be used for ignition guns, etc.

[0018] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In the description of the present utility model, it should be understood that the terms "connected", "connected", "fixed" and the like used in the present utility model should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or integrated; it can be a mechanical connection or a welding connection; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] like Figure 1 , Figure 2 As shown, the first embodiment of a lighter with a large flame gas ignition device of the utility model, a large flame gas ignition device, which is installed in the gas outlet 12 of the shell 1, and the shell is also provided with a gas storage box 2, a gas outlet valve 3 placed on the gas storage box 2, a gas control device 4 for controlling the action of the gas outlet valve 3, and a spark generating device 9 arranged near the gas outlet. The gas outlet valve 3 is connected to the ignition device through the gas pipe 5, including a base 6 connected to the end of the gas pipe 5 and in a tubular shape with a central through hole 65, and the top section of the base 6 is provided with a plurality of gas expansion areas, and a plurality of gas expansion holes penetrating the base tube wall are opened in the gas expansion area, and the plurality of gas expansion holes are arranged along the length direction of the base in the gas expansion area. The expansion holes in this embodiment are connected to form long slot-shaped expansion grooves, that is, several expansion areas are arranged asymmetrically on the cross section of the tube wall, and multiple expansion holes along the length direction of the substrate in the expansion area are connected to form a long slot-shaped expansion groove 61, that is, the expansion groove extends upward from the top section of the substrate 6 to the opening of the substrate 6, and wind-proof prism walls are formed between the two expansion grooves. The expansion grooves 61 described in the cross section of the tube wall correspond to wind-proof prism walls 62 at the left-right symmetrical positions, thereby forming a wind-proof structure that does not penetrate horizontally. The substrate of this embodiment is arranged with three slots evenly distributed along the ring. Of course, other numbers of long slots can be opened as needed, as long as the long slots are not opened symmetrically. The non-left-right symmetrical layout can prevent the crosswind from passing through in diameter, protect the fire core, and make it have a certain wind resistance.

[0020] On the top section of the base of the present embodiment, one or several ring members 7 are sleeved near the opening position, and the peripheral wall of the ring member 7 has a large number of micropores 71 penetrating the peripheral wall. The thickness of the ring member is less than the length of the gas expansion zone. The ring member 7 is arranged on the gas expansion zone. Due to the thickness relationship and the micropores, the covering effect on the long groove is very small, and the ring member 7 with a large number of micropores further thickens the root of the flame. At the same time, compared with the long groove and the top outlet, the micropores have a certain slow-release diffusion of fuel gas, lengthening the root of the flame and protecting the flame core. When the flame is blown, the micropores also play a temporary gas storage for the flame core to be extinguished layer by layer, further improving the wind resistance and the ability to not be blown out. The ring member 7 sleeved at intervals ensures that the gas expansion of the long groove can lengthen the length of the slow-release section, thereby lengthening and thickening the flame.

[0021] In order to improve the success rate of ignition spark formation, the present embodiment has an ignition piece 8 corresponding to the spark generating device wound on the top section of the base 6, and the ignition piece 8 at least partially passes through the gas expansion zone on the base. The ignition piece of the present embodiment is a spring with a pitch. It has low cost and is easy to assemble. Of course, other metal parts can also be used.

[0022] The top surface of the substrate in this embodiment is flush with the air outlet 12. Of course, due to the open flame with a large flame, for safety reasons, the free top of the substrate with the air expansion area can be exposed at the air outlet position, that is, the air expansion area is partially exposed at the air outlet.

[0023] like Figure 3 , Figure 4 As shown, the second embodiment of the utility model of the gas ignition device lighter with a large flame, the gas expansion holes of this embodiment are slotted slots 63, that is, the multiple slotted gas expansion holes in the gas expansion area are not connected, and the slotted holes achieve wind blocking and fire core protection through the non-connected tube walls between the slots 63. Since the adjacent slots are not connected, there is no opposite straightness of the side wind, and there is no need to consider whether the gas expansion area is symmetrical and spaced. As shown in the present embodiment, the gas expansion areas can be arranged with intervals between the gas expansion areas in the circumferential direction, or the gas expansion holes can be arranged to cover the gas expansion areas, and the gas expansion areas can be arranged without intervals in the circumferential direction, that is, a large number of gas expansion holes are arranged on the top section of the base 6 to form a top gas expansion section. The size of the gas expansion holes, the number of gas expansion holes and the spacing layout of the gas expansion areas can be designed according to needs.

[0024] The utility model, whether it is the air expansion area or the ring member 7 and the ignition member 8, are all designed as a base connected to the conduit inside the air outlet. The base can even be integrated with the conduit, and is not arranged on the periphery of the flame. It has high safety. Its windproof and non-extinguishing property is aimed at the flame itself, that is, the flame root core protection, breaking the windproof limitation barrier of the windproof sleeve on the periphery of the flame, providing another windproof technology research and development direction for open flame lighters and even open flame equipment.

[0025] Although the present invention has been disclosed as above in terms of specific embodiments, it is not intended to limit the present invention. Any technician in the field may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the attached claims.
