Abstract

Disclosed is an igniter gas bottle with high compressive strength, the igniter gas bottle comprising a body (1), a cover (2) and a sealing bowl (3), wherein the outer side of the upper end of the body (1) is provided with an upper outer inclined welding face (11) that inclines inwards, the lower end of the periphery of the cover (2) is in sealed connection with the body (1), the inner side of the lower end of the periphery of the cover (2) is provided with an upper inner inclined welding face (23), and the sealing bowl (3) is arranged at a lower section (213) of a hollow hole (21) of the cover (2). Before the body (1) is welded to the cover (2), the angle of inclination of the upper outer inclined welding face (11) is greater than that of the upper inner inclined welding face (23). With regard to the defect of an existing igniter gas bottle having low compressive strength, the body (1) and the cover (2) of the igniter gas cylinder with high compressive strength are mutually stressed before being welded to each other, and therefore, the upper outer inclined welding face (11) and the upper inner inclined welding face (23) can be better welded into a whole.

Abstract

A lighter gas cylinder having a good sealing effect, comprising: a body (1), which is provided with an accommodating chamber that can accommodate liquefied flammable gas; a cover (2), which is integrally injection molded, wherein an outer edge of the lower end of a hollow part is provided with a cold slug (22), the hollow part is provided with a hollow hole (21), and the hollow hole (21) comprises an upper section (211), a middle section (212), and a lower section (213); a sealing bowl (3), which is disposed in the lower section (213) of the hollow hole (21) of the cover (2); and a valve assembly (4), which is located in the hollow hole (21). The described lighter gas cylinder transfers, to the outer edge of the lower end of the hollow part of the cover, a welding mark that is originally generated in the hollow hole of the cover adjacent to the sealing bowl, the welding mark being relatively far from a sealing surface, thus the pressure-resistance strength of the gas cylinder is improved, and the sealing effect is ensured.
