Description

Technical Field

[0001] The utility model relates to a gas ignition device, in particular to an ignition device of 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 that is difficult to burn, such as cigars. 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 covers around the ignition port on the shell. First, the windproof cover is easy to burn the user on the periphery of the flame. Secondly, the windproof cover increases the cost and reduces the aesthetics of the lighter. At the same time, the windproof cover easily makes the flame further reduced. Summary of the invention

[0003] The utility model provides a safe gas ignition device with certain fire core protection and windproof functions.

[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 fire outlet of the shell, and the shell is also provided with an air storage box, an air outlet valve placed on the air storage box, and an air control device for controlling the action of the air outlet valve. The air outlet valve is connected to the ignition device through an air pipe. The ignition device includes a tubular base connected to the end of the air pipe and with a central axis hole. The top section of the tubular base has a plurality of air expansion grooves that penetrate the wall of the tubular base. The air expansion grooves are arranged at intervals between each two on the wall of the tube. One or more ring members are embedded in the top section with the air expansion grooves. The peripheral wall of the ring member has a large number of micro pores that penetrate the ring body. The center hole of the ring member is connected to the central axis hole. The ring member forms a slow-release air storage belt in the top section of the tubular base.

[0005] As an improvement: windbreak prism walls are formed between the air expansion grooves on the top section, and the windbreak prism walls correspond to the left-right symmetrical positions of the air expansion grooves on the cross section of the tubular base, thereby forming a transversely non-intersecting windbreak structure.

[0006] As an improvement: the tubular base is connected to the end of the trachea through a telescopic extension tube, which is a telescopic tube section connected to the lower tail of the tubular base or an extended sleeve inner tube slidably sleeved on the lower part of the tubular base.

[0007] As an improvement: the free top of the tubular base is higher than the position of the fire outlet, that is, the top section of the tubular base with the gas expansion groove is partially exposed at the fire outlet.

[0008] As an improvement: a spark generating device is further arranged in the shell near the fire outlet, an ignition piece corresponding to the spark generating device is wound around the tubular base, and the ignition piece at least partially passes through the top section of the gas expansion groove on the base.

[0009] The beneficial effects provided by the utility model are as follows: since the tube wall of the top section of the tubular matrix is ​​not closed, the fuel gas is not only released outward from the top of the tubular matrix, but also diffuses outward from the air expansion holes in 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 matrix, and the flame surrounds the top section of the matrix to form a thick root of the flame or a fire core. Due to the setting of the ring member embedded in the top section of the tubular matrix, the combustion gas in the center hole diffuses to the outer periphery of the tubular matrix through a large number of micropores and the air expansion groove to form a fire core. The ring member forms a slow-release gas storage belt in the top section of the tubular matrix. When blowing, the ring member can protect the center of the fire core and play a certain wind resistance. That is, the utility model has the windproof protection structure built into the tubular matrix, which is not touched by the user and has high safety.

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.

[0015] like Figure 1 , Figure 2 , Figure 3 As shown, an embodiment of a lighter with a gas ignition device of the utility model, the gas ignition device is installed in the fire outlet 12 of the shell 1, and the shell is also provided with a gas storage box 2, an air outlet valve 3 placed on the gas storage box 2, a gas control device 4 for controlling the action of the air outlet valve 3, and a spark generating device 9 near the fire outlet. The air outlet valve 3 is connected to the ignition device through the air pipe 5, and the ignition device includes a tubular base 6 connected to the end of the air pipe 5 and with a central axis hole 62. The top section of the tubular base 6 is provided with a plurality of gas expansion grooves 61 penetrating the wall of the tubular base, and the gas expansion grooves 61 are arranged at intervals between each other on the wall of the tube. An ignition piece 8 corresponding to the spark generating device is wound around the tubular base 6, and the ignition piece 8 passes through the top section of the base at least partially where the gas expansion grooves are arranged. One or more ring members 7 are embedded in the top section with the gas expansion groove 61. The peripheral wall of the ring member 7 has a large number of micropores 71 that penetrate the ring body. The center hole 72 of the ring member is connected to the center axis hole 62. The ring member forms a slow-release gas storage belt in the top section of the tubular base 6. Wind-blocking prism walls are formed between the two gas expansion grooves on the top section of this embodiment, and the wind-blocking prism walls correspond to the left-right symmetrical positions of the gas expansion grooves on the cross section of the tubular base, thereby forming a wind-blocking structure that does not penetrate horizontally, so that the wind cannot penetrate through and extinguish the fire core, further improving the wind resistance of the lighter flame. The gas expansion groove can be a straight groove or a curved groove design. Of course, the gas expansion groove can also be a slot hole type, and the slot hole aperture is much larger than the aperture of the micropore 71.

[0016] In order to facilitate the use of open flames, the open flame can be designed to be extendable. There are various extendable schemes. In order not to affect the design of the upper part of the tubular base 6, the following scheme (not shown in the figure) can be adopted: the tubular base 6 is connected to the end of the gas pipe 5 through a retractable extension pipe, and the extension pipe is a retractable pipe section connected to the lower tail of the tubular base 6 or an extended sleeve inner pipe that can be slidably sleeved on the lower part of the tubular base 6. For easy extension, the free top of the tubular base 6 can also be higher than the position of the fire outlet 12, that is, the top section of the tubular base 6 with the gas expansion groove is partially exposed at the fire outlet 12. The exposed design can also accelerate the mixing of gas and air, further improve the thickness of the flame, and can also be used as a manual ignition device before ignition.

[0017] 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.
