Description

Technical Field

[0001] The utility model relates to the technical field of lighters, in particular to a windproof lighter with good low-temperature ignition performance. Background Art

[0002] A windproof lighter, as an ignition device, consists of a housing, a hood, a trigger, an ignition mechanism, a gas tank assembly, a direct-flow nozzle, a filter, a silver plate, a mixing chamber, a burner, a ceramic cup, a burner head, and an ignition device. Gas passes through the holes in the silver plate and mixes thoroughly with air in the mixing chamber. Most of the gas is ejected from the center of the direct-flow nozzle, producing a strong, rod-shaped, high-heat direct-flow flame. A small portion of the gas enters smaller holes around the direct-flow nozzle, producing multiple smaller flames to help maintain the central flame. The windproof direct-flow flame is particularly suitable for thick or hard tobacco, especially for lighting cigars. While the windproof direct-flow flame burns intensely, reaching temperatures of approximately 1300°C, typical windproof lighters can experience common flame performance issues at temperatures as low as 0°C: low ignition efficiency and misfires. As a daily lighting tool, the ignition rate of lighters directly impacts the user experience.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

[0004] The utility model provides a windproof lighter with good low-temperature ignition performance. The air intake, outlet and combustion structures of the windproof lighter are improved to have a high ignition rate and high combustion efficiency. It can adapt to the ignition requirements in a low-temperature environment of -5 to 0°C, and overcomes the shortcomings described in the background technology.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A windproof lighter with excellent low-temperature ignition performance includes a shell, a wind cover, a button, an ignition device, an air outlet assembly, an air box, and a gas nozzle assembly. The button is vertically slidably mounted on the shell. The ignition device includes a piezoelectric device. The bottom end of the button presses the piezoelectric device through a pry plate. The bottom end of the air box is sealed by a bottom cover. A wind cover is provided on the gas nozzle assembly. The air outlet assembly includes an air outlet regulating valve that can adjust the air outlet volume. The gas nozzle assembly includes a straight-in nozzle and a combustion furnace assembly. The combustion furnace assembly includes a gas mixing chamber connected to the air outlet regulating valve. The straight-in nozzle includes a central hole and a plurality of small holes. The small holes are arranged around the central hole.

[0007] By optimizing the gas and air mixing space and the combustion furnace structure, an improved windproof lighter with good low-temperature ignition performance and high ignition efficiency is provided to enhance the user experience.

[0008] A better technical solution: the wind cover includes an inner wind cover and an outer wind cover. The inner wind cover is nested on the top of the combustion furnace assembly, and the outer wind cover is nested outside the inner wind cover.

[0009] A preferred technical solution: it also includes a fire regulating ring, which is nested on the air outlet regulating valve.

[0010] A better technical solution: The combustion furnace assembly also includes an iron sleeve, a porcelain cup, a ferrule, a furnace body, a connecting piece, a silver sheet, an O-ring, a filter, a base, and a sealing ring. The iron sleeve and the porcelain cup are nested, the ferrule is nested at the bottom of the furnace body, and the furnace body is connected to the base through a connecting piece. A silver sheet, an O-ring, and a filter are set at the bottom of the connecting piece, and a sealing ring is nested at the bottom of the base.

[0011] A preferred technical solution: the air outlet regulating valve is fastened in the shell through a threaded sleeve.

[0012] A better technical solution: the thickness of the porcelain cup is 0.7-0.8mm.

[0013] A preferred technical solution: a silver hole is passed through the center of the silver sheet, and the radius of the silver hole is 0.03-0.035mm.

[0014] A preferred technical solution: the radius of the center hole is 0.5-0.525 mm.

[0015] A preferred technical solution: a plurality of ventilation holes are provided on the outer air hood.

[0016] A better technical solution: an air intake assembly is set at the bottom of the air box.

[0017] By adopting the above technical solution, the beneficial effects of the utility model are:

[0018] 1. When the lighter of the present invention is operated in a low temperature environment of 0°C, there is more space in the combustion chamber, the gas fuel and oxygen are fully mixed, and it is easier to ignite the fire;

[0019] 2. When the lighter of the present invention works in a low temperature environment of 0℃, the hole in the silver sheet becomes larger, the central hole of the nozzle becomes smaller, the surrounding holes become larger, and the thickness of the ceramic cup increases, so that the central airflow is more concentrated, the surrounding small fires last longer, the fuel utilization rate is higher, and the fire flame is larger.
