Description

Storage device for guaranteeing essential oil quality Technical Field The utility model relates to the technical field of essential oil storage, in particular to a storage device for guaranteeing the quality of essential oil. Background Essential oils are widely used in many fields such as aromatherapy, massage, skin care product addition, etc. due to their unique fragrance and various effects. However, essential oils are highly volatile, easily oxidized, and susceptible to light and temperature effects, resulting in reduced quality. The existing essential oil storage device is mainly a simple glass bottle or a plastic bottle, the bottle mouth is sealed only through a screw cap, the sealing effect is poor, oxygen can not be effectively prevented from entering the bottle mouth and essential oil is volatilized, and the essential oil is easy to chemically react due to illumination under long-time storage without shading measures or unsatisfactory shading effects, so that the quality and the efficacy of the essential oil are influenced, and even harmful substances are possibly generated due to deterioration, so that the requirement of people on high-quality essential oil storage can not be met. Therefore, a storage device capable of guaranteeing the quality of the essential oil is urgently needed. Disclosure of utility model The utility model aims to provide a storage device for guaranteeing the quality of essential oil, which can ensure the stable quality of the essential oil in the storage process by optimizing a sealing structure, adding an antioxidant function and shading design, and effectively solves the problems of poor sealing performance, poor shading effect, easiness in oxidization and the like of the existing essential oil storage equipment. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The storage device for guaranteeing the quality of the essential oil comprises a tank body and a tank cover, wherein an inner container for storing the essential oil is arranged in the tank body, an opening is formed in the top of the inner container, a sealing cavity is formed between the inner container and the tank body, inert gas is filled in the sealing cavity, the tank cover is provided with a silica gel sealing plug which is tightly matched with the opening of the inner container, the outer wall of the tank body is provided with a shading layer made of a plurality of layers of composite materials, and the shading layer comprises an aluminum foil layer located on the outer layer, a fiber reinforced layer located on the middle layer and an EVA layer located on the inner layer. Further, the inner container is of a double-layer structure, and comprises a high borosilicate glass layer positioned on the inner layer and a heat-insulating coating positioned on the outer layer. By adopting the form of a double-layer structure and being provided with the heat-insulating coating, the heat-insulating performance of the liner is enhanced, and the influence of external temperature on essential oil is reduced. Further, the opening of the inner container is provided with a positioning ring which is distributed in an annular mode and is used for being abutted to the silica gel sealing plug, and the upper portion of the high borosilicate glass layer is fixedly connected with the positioning ring.
