Description

Technical Field

[0001] The utility model belongs to the technical field of gas cylinders and relates to a food-grade aluminum alloy gas cylinder. Background Art

[0002] Common edible gas is generally carbon dioxide, which is mainly used to be injected into beverages that originally did not contain gas to improve the taste of the beverage. The carbon dioxide that needs to be injected is usually stored in the gas cylinder of the sparkling water machine. When sparkling water needs to be produced, the carbon dioxide in the gas cylinder can be filled into the beverage bottle through the sparkling water machine; Patent No. CN202121448665.0 discloses an edible-grade aluminum alloy gas cylinder, which belongs to the field of gas cylinders and includes a valve and an integrally formed bottle body. Once the internal pressure of the gas cylinder is large, the deformation will be concentrated at the center of the concave surface. Because there is a groove under the bottom of the bottle, the thickness of the center position of the bottle bottom is further reduced. Therefore, the deformation will occur completely at the groove. Since the groove is still a distance away from the bottom of the bottle, even if deformation occurs, it will not affect the stability of the bottle bottom, which solves the problem in the existing technology that the bottle bottom is easily deformed and unstable.

[0003] The above-mentioned gas cylinder has the disadvantage of lacking a structure for mounting an identification plate. In the prior art, identification plates are mostly riveted and cannot be effectively disassembled and replaced. Therefore, we design a food-grade aluminum alloy gas cylinder.
