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-discharging device which is safe, can produce thick and hard-to-extinguish flames.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a gas ignition device, which is installed in the gas outlet of the shell, and is also provided with a gas storage box, a gas outlet valve placed on the gas storage box, a gas control device for controlling the action of the gas outlet valve, and a spark generating device arranged near the gas outlet. The gas outlet valve is connected to the ignition device through an air pipe, and includes a tubular base connected to the end of the air pipe. The top section of the base is provided with a plurality of gas expansion grooves that penetrate the tube wall of the base, and the gas expansion grooves are arranged at intervals between each other on the peripheral wall of the tube.

[0005] As an improvement, the gas expansion groove extends non-linearly on the base.

[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: the top section of the base body is in a multi-layer sleeve-connected shape with spacing, and the air expansion grooves are arranged in a staggered manner on each layer.

[0008] As an improvement: the top section of the base body is partially exposed at the air outlet.

[0009] The beneficial effects provided by the utility model are as follows: 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 air expansion hole of the top section to mix with the air. After being ignited by the spark, an upward flame is formed from the top section of the substrate, and the flame surrounds the top section of the substrate to form a thick root of the flame or a fire core. Compared with the existing fire-emitting device, the central fire core position of the fire-emitting device of the utility model is lower, and the tube wall of the air expansion groove is spaced to form a wind-proof prism wall that can block the wind, which has a certain windproof property, especially ensuring that the flame is not extinguished when shaking. The structure has an invisible windproof wall that cannot be touched by the user and has high safety. Furthermore, the non-linear air expansion groove is conducive to an asymmetric design and has stronger wind resistance. At the same time, the fire-emitting device has a simple structure, is easy to implement, is low-cost, safe, and has a certain versatility, that is, it can also be used for ignition guns, etc.

[0016] 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.

[0017] like Figure 1 , Figure 2 As shown, the first embodiment of the lighter with the gas ignition device of the utility model, the gas ignition device is installed in the gas outlet 12 of the housing 1, and the housing 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 air pipe 5, including a tubular base 6 connected to the end of the air pipe 5, and the top section of the base 6 is provided with a plurality of gas expansion grooves 61 penetrating the base tube wall, and the spacing between the gas expansion grooves is arranged on the tube wall. The gas expansion grooves 61 extend non-linearly on the base, and in this embodiment, they are oblique grooves, and of course, they can also be curved grooves. The base of this embodiment is arranged with three grooves evenly distributed along the ring, and of course, other numbers of long grooves can be opened as needed, and the long grooves only need to be opened non-symmetrically. The non-symmetrical layout can prevent the crosswind from passing through the diameter, protect the fire core, and make it have a certain wind resistance.

[0018] 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 oblique 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 oblique groove and the top outlet, the micropores have a certain slow-release diffusion of fuel gas, lengthen the root of the flame, and protect 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 oblique groove can lengthen the length of the slow-release section, thereby lengthening and thickening the flame. The top surface of the base 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 top section of the base 6 can be partially exposed at the air outlet.

[0019] like Figure 3 , Figure 4 , Figure 5 As shown, the second embodiment of the gas ignition device lighter of the utility model, the gas expansion hole of this embodiment is a slotted hole, the top section of the base 6 is in a multi-layer sleeve shape with spacing, and the gas expansion grooves 61 are arranged in a staggered manner on each layer. The spacing setting and staggered arrangement between the multiple layers not only make the top of the base with the gas expansion grooves 61 have a windbreak wall, but also form a short-term gas storage between the layers, which has a better effect of protecting the fire core.

[0020] The utility model, whether it is the air expansion groove 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.

[0021] 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.
