Problems solved by technology

At present, the air guide assembly includes a separate drainage core, aluminum sleeve and foam pad. During installation, workers need to install the aluminum sleeve, drainage core, and foam pad into the matrix in sequence. The assembly efficiency is low, and it is easy to remove the foam The pad is installed reversely, resulting in a high scrap rate of lighters

Embodiment 1

[0048] An integrated assembled gas guide assembly for a lighter, such as Figures 1 to 3 As shown, it includes: a metal sleeve 1 for assembling with the lighter body, and a ventilation structure is provided on the metal sleeve 1; a drainage core 2 that penetrates in the metal sleeve 1 and extends to the bottom of the lighter body, and is used to lead out combustible gas; And, the air filter assembly 3 embedded in the metal sheath 1 and located above the drainage core 2 is clamped and fixed with the metal sheath 1 .

[0049] Specifically, a metal sleeve 13 is provided at the bottom of the metal sleeve 1, and the metal sleeve 1 and the metal sleeve 13 are integrally formed. Both the metal sleeve 1 and the metal sleeve 13 can be made of metal materials such as copper, aluminum, iron, and metal alloys. The ventilation structure is an air passage 11 opened on the metal sheath 1, the air passage 11 runs through the side wall of the metal sheath 1 and extends from the upper end surfa...

Embodiment 2

[0054] The difference between this embodiment and Embodiment 1 is that: Figure 4 with Figure 5 As shown, in this embodiment, the air filter assembly 3 includes: a constant flow filter 33, and a snap ring 34 arranged above the constant flow filter 33 for clamping and fixing the constant flow filter 33, the metal sleeve 1 The upper end of the upper end and the clamping ring 34 are tightly clamped, and the constant current filter 33 is pressed and fixed. The clamping ring 34 is a metal ring. Of course, in practical applications, it can also be set on both sides of the constant current filter 33. The snap ring 34, through the constant flow filter 33, the combustible gas can be drawn out at a constant flow rate, so that there is no need to adjust the gas flow during use, and it is more convenient to use. At the same time, the snap ring 34 is locked with the metal sleeve 1 Connect to realize the fixing of the constant current filter sheet 33.

[0055] Moreover, a gasket 35 is al...

Embodiment 3

[0058] The difference between this embodiment and Embodiment 1 is that: Figure 6 to Figure 8 As shown, in this embodiment, the metal sleeve 13 is not provided at the bottom of the metal sheath 1 to form a plane. At this time, the ventilation structure is also the air channel 11 opened on the metal sheath 1, and the air channel 11 runs through the side of the metal sheath 1. The wall extends from the upper end surface of the metal sheath 1 to the lower end surface, and the air channels 11 are arranged symmetrically on both sides of the metal sheath 1, or a plurality of them are evenly arranged around the circumference of the metal sheath 1, and the air is fed through the air channels 11 when inflated. , After the inflation is completed, the gas is released, which makes the flame of the lighter burn more stable.

Abstract

The invention relates to a lighter and an integrally-assembled type gas guide assembly thereof. The gas guide assembly comprises a metal sleeve, a drainage core and a gas filtering assembly, wherein the metal sleeve is used for being assembled with a lighter body, and a ventilation structure is arranged on the metal sleeve; the drainage core is arranged in the metal sleeve in a penetrating mode and extends to the bottom of the lighter body; the gas filtering assembly is embedded in the metal sleeve and located above the drainage core, and the gas filtering assembly is clamped and fixed to themetal sleeve; and the gas filtering assembly comprises a constant-current filtering piece and a clamping ring which is arranged above the constant-current filtering piece and used for clamping and fixing the constant-current filtering piece. According to the gas guide assembly, the gas guide assembly is assembled into a whole, so that the phenomenon that the gas filtering assembly is reversely assembled cannot occur during assembly, and therefore the rejection rate of the lighter is reduced; meanwhile, combustible gas can be led out at constant flow by arranging the constant-current filteringpiece, so that gas flow adjustment is not needed during use, and use is more convenient.

Description

technical field [0001] The invention relates to the technical field of lighters, in particular to a lighter and an integrated assembled air guide assembly thereof. Background technique [0002] Lighters are currently the most commonly used ignition devices. my country is the country with the largest production and consumption of lighters in the world. The annual demand for lighters in the country is about 12 billion. Common civil lighters usually include a body, a gas guide assembly and an ignition assembly. The combustible gas filled in the matrix is ​​led out through the gas guide assembly, and the ignition assembly ignites the combustible gas to complete the ignition action. At present, the air guide assembly includes a separate drainage core, aluminum sleeve and foam pad. During installation, workers need to install the aluminum sleeve, drainage core, and foam pad into the matrix in sequence. The assembly efficiency is low, and it is easy to put the foam The pad is inst...
