Aluminum pressure cooker body with oxidation film

Abstract

The invention discloses an aluminum pressure cooker body with an oxidation film. The aluminum pressure cooker body comprises a cooker cover, a bearing is installed on the inner side of the cooker cover, a pressure relieving column is installed on the inner side of the bearing, a sector plate is installed on one side of the pressure relieving column, a pressure relieving hole is formed in the upperend of the sector plate, a pressure relieving groove is formed in the upper end of the pressure relieving hole, an upper handle is installed on one side of the cooker cover, an upper locking buckle is installed on the outer surface of the cooker cover, a lower locking buckle is installed on the inner side of the upper locking buckle, a protection shell is installed on one side of the lower locking buckle, a handle is installed on one side of the protection shell, a lower handle is installed on the other side of the protection shell, a heat preservation and insulation layer is installed on theinner side of the protection shell, and a cooker main body is installed on one side of the heat preservation and insulation layer. According to the aluminum pressure cooker body, as the protection shell is installed in cooperation with the heat preservation and insulation layer, the cooker body has a heat preservation and insulation function; through oxidation treatment of the cooker main body, the corrosion resistance and practicability of the cooker body are improved.

Description

technical field [0001] The invention relates to the technical field of a pressure cooker body, in particular to an aluminum pressure cooker body with an oxide film. Background technique [0002] With the rapid development of social economy, the pressure cooker is a kind of kitchen pot. The pressure cooker uses the physical phenomenon that the boiling point of the liquid will increase at a higher pressure, and puts pressure on the water so that the water can reach a higher temperature without boiling. Accelerate the efficiency of stewing food, use it to heat the cooked food to over 100 degrees Celsius, in high altitude areas, use pressure cooker to avoid the problem that the boiling point of water is lowered and it is not easy to cook food, its advantages are time-saving and energy-saving, The disadvantage is that when it is operated incorrectly or has defects, it may explode and cause damage. When the air pressure is greater than one atmospheric pressure, the water will boil...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an aluminum pressure cooker body with an oxide film to solve the problem that the aluminum pressure cooker body proposed in the background technology has not been oxidized, has no safety protection measures, cannot carry out thermal insulation and pressure relief holes. It will be blocked by food debris, resulting in problems such as failure to release pressure and danger
