Portable pressure cooker

Abstract

The invention provides a portable pressure cooker. The pressure cooker comprises a cooker body and a cover. The pressure cooker is characterized in that the cooker body comprises an outer cooker bodyand an inner cooker body, the inner cooker body is sleeved with the outer cooker body and connected with the outer cooker body through a cover ring and a clamp ring, a cavity used for placing self-heating materials is formed in the part between the inner cooker body and the outer cooker body, and a pressure limiting valve and / or a safety valve communicated with the cavity is arranged on the side face of the cooker body. By arranging the inner and outer cooker bodies and placing the self-heating materials in the cavity formed in the part between the inner and outer cooker bodies, automatic heating can be conducted by adding in water to cook foods in the inner cooker body, so that the use of the cooker in an environment without heating sources in the field is convenient; by arranging the safety valve on the side of the outer cooker body and arranging an exhaust valve on the cover, the pressure cooker is safe and reliable to use; by fixing the inner cooker body and the outer cooker body through the clamp ring and the cover ring, the disassembly and assembly of the pressure cooker are convenient, and the sealing performance is good; the outer cooker body is divided into two layers, theouter layer is a heat preserving layer, heat does not disperse easily, the heat preserving performance is good, and cooking is faster. The pressure cooker has the advantages of being simple and reasonable in structure, convenient to dismantle and assemble and safe and reliable to use.

Description

technical field [0001] The invention relates to a kitchen cooker, in particular to an energy-saving pressure cooker. Background technique [0002] A pressure cooker, also known as a pressure cooker, is an energy-saving cooking pot. Pressure cookers elevate this physical phenomenon by allowing liquids to boil at higher air pressure, applying pressure to the water so that the water can reach higher temperatures without boiling to speed up the efficiency of stewing. It can be used to heat the food to be cooked to more than 100 ℃. In high altitude areas, the use of a pressure cooker can avoid the problem that the boiling point of water is lowered and the food is not easy to cook. The advantage of the pressure cooker is that not only the cooking time is short, but also the cooked food tastes good, especially the meat that is not easy to cook becomes easy to cook and tastes good. Existing pressure cookers are all heated by electricity or gas. If they are operated in the field an...
