Storage containers commonly used for liquids such as red wine, beverages, oils are mostly simple containers, e.g. glass bottles. After pouring a part of liquid from the container, air enters the container, oxidation reaction is easy to occur to the residual liquid in the container, such as a common red wine bottle, after the red wine bottle is opened, the red wine is easy to be oxidized and deteriorated by oxygen in the air, when part of red wine is still left in the red wine bottle, the red wine is easy to be oxidized by the air in the bottle, the storage life is short, and the taste difference is large when the red wine is drunk again.

If the wine needs to be stored for a longer time, the oxidation reaction of the wine liquid and oxygen in the air is basically reduced as much as possible, and the traditional storage method comprises the following steps:

The wine cabinet is refrigerated, the wine cabinet is not isolated from air, has no practical and obvious effect on slowing down oxidization, and has the main effect of storing wine which is not bottled, and if the wine cabinet is placed in a refrigerator for refrigeration, the too low temperature can cause obvious damage to the taste quality of red wine.

The bottle is replaced after being opened, the operation is troublesome, the volume of the bottle is fixed, and the proper size can not be adjusted according to the amount of the residual wine.

The vacuum plug can not be adjusted along with the air extraction due to the fixed volume of the wine bottle, and a large amount of air still exists in the bottle, so that the effect of preventing oxidization is not obvious.

The method for filling the wine bottle with the inert gas has the advantages that the operation is complicated, expensive professional machines and expensive inert gas consumable materials are needed, the inert gas can not be injected after the bottle is opened, oxygen can not be completely isolated, the oxygen content in the bottle and the contact oxygen amount of wine liquid are only reduced, the machine equipment is large in size, the inert gas consumable materials are expensive, the large-scale popularization value is not achieved, the raw wine plug is required to be used by the other method for injecting the inert gas without opening the bottle, the raw wine plug is not used by most of the wine sold on the market, the application range of the raw wine plug can not cover most of the wine sold on the market, but the equipment is expensive, the consumption of the consumable materials is large, the cost is high, and the operation is complicated.

The method and the device have the problems of poor oxidation prevention effect, high equipment and consumable cost, complex operation and inconvenient use after the wine is stored and opened.

The piston 22 comprises a float 230 connected to the air duct 21 and a sealing ring 220 sleeved on the periphery of the float 230, wherein the float 230 and the sealing ring 220 are made of food grade materials. When the air duct 21 moves up and down with respect to the container 10, the seal ring 220 is closely attached to the inner surface of the container 10. When the gas guide tube 21 drives the piston 22 to move downwards relative to the container 10, a gap is formed between the sealing ring 220 and the floater 230, so that gas can flow into the gas guide tube 21 through the gap and be discharged from the top opening of the gas guide tube 21.

When the float 230 moves until the bottom surface of the float 230 is fully contacted with the liquid, the outer peripheral side wall of the float 230 is tightly attached to the sealing ring 220, the plug 30 is linked with the float 230, and the plug 30 can drive the float 230 to rise when rotating along a preset direction. When the float 230 moves downwards until the air can not move downwards any more, air exhaust is completed, at this time, the plug 30 is inserted into the opening at the top of the air duct 21, and then when the plug 30 rotates along a preset direction, the float 230 is driven by the plug 30 to rise for a certain distance, at this time, the float 230 is further clung to the sealing ring 220, and further the gap between the sealing ring 220 and the float 230 is closed, so that external air is not easy to enter the container 10 from the air duct 21 to contact with liquid, the sealing effect is good, the anti-oxidation function of the storage device can be improved, and the fresh-keeping time is prolonged.

In the storage device provided in this embodiment, when the air duct 21 drives the piston 22 to move downwards relative to the container 10, a gap is formed between the sealing ring 220 and the float 230, air can flow into the air duct 21 through the gap and is discharged from the opening at the top end of the air duct 21, the float 230 moves to contact with the liquid surface until the float 230 rises when the air discharge is completed, the gap between the float 230 and the peripheral sealing ring 220 gradually decreases, after the air discharge is completed, the float 230 is primarily clung to the sealing ring 220, and as the plug 30 and the float 230 are linked, the plug 30 is inserted into the air duct 21, the plug 30 can drive the float 230 to rise when rotating in a predetermined direction, so that the float 230 and the sealing ring 220 can be further clung to realize the isolation of liquid and air in the container 10, the outside air is not easy to enter the container 10 from the gap between the sealing ring 220 and the float 230, the deterioration process of the liquid is slowed down, the better anti-oxidation effect can be realized, and the fresh-keeping time is long.

In an embodiment, as shown in fig. 3 and 5, the top end of the float 230 is connected with a driving rod 240, the driving rod 240 is accommodated in the air duct 21, the plug 30 forms a linkage structure with the float 230 through the driving rod 240, the driving rod 240 can be driven to rotate when the plug 30 rotates along a predetermined direction (such as the direction F1 in fig. 5 and 8), and the driving rod 240 can be driven to rise relative to the air duct 21 when being driven to rotate by the plug 30. When the stopper 30 is removed from the air duct 21, the liquid in the container 10 can flow out from the gap between the float 230 and the seal ring 220, and the liquid in the container 10 can be poured out through the air duct 21 when pouring the container 10. When the air exhaust operation is performed, the plug 30 can be pulled out, and force is applied to the air duct 21, so that the air duct 21 drives the piston 20 to move downwards, the float 230 can not descend any more when the float 230 is in contact with the liquid surface to exhaust air, at the moment, the plug 30 is inserted into the air duct 21, the plug 30 is rotated for a certain angle in a preset direction, the plug 30 lifts the float 230 through the driving rod 240, the float 230 ascends at the same time, and the peripheral side wall of the float 230 can be further clung to the sealing ring 220. When the liquid in the container 10 needs to be poured out, the plug 30 is rotated in the direction opposite to the preset direction, the driving rod 240 is driven to the unlocking position, meanwhile, the driving rod 240 moves slightly downwards relative to the air duct 21, meanwhile, the float 230 is driven to move slightly downwards, the plug 30 is pulled out, the further clinging state of the float 230 and the sealing ring 220 is relieved, the air duct 21 is further moved upwards by external force, the driving rod 240 and the float 230 are driven to move upwards, the float 230 and the driving rod 240 descend due to self gravity, a gap is formed between the peripheral side wall of the float 230 and the sealing ring 220, the container 10 is inclined, and the liquid in the container 10 can flow out along the inner wall of the air duct 21.

In one embodiment, as shown in fig. 3 and 7, the bottom surface of the plug 30 is concavely formed with a groove 310, and a locking structure is formed between the wall of the groove 310 and the driving rod 240. When the air duct 21 drives the piston to move downwards and the floater 230 is not contacted with the liquid in the container 10, the driving rod 240 and the floater 230 are in a free suspension state, a gap is formed between the outer peripheral side wall of the floater 230 and the sealing ring 220, and air can flow out of the gap in the process of moving downwards by the air duct 21 and then is discharged through the air duct 21. When the float 230 moves to contact with the liquid in the container 10 until the air exhaust is completed, the float 230 rises to a predetermined height due to the buoyancy of the liquid, at this time, the driving rod 240 rises to the unlocking position, and the top end of the driving rod 240 stretches into the groove 310, so that the driving rod 240 can be driven to rise relative to the air duct 21 through the locking structure when the plug 30 rotates in a predetermined direction, and the peripheral side wall of the float 230 is further clung to the sealing ring 220. That is, in this process, the float 230 has two rising actions, the first is that the exhaust gas is raised by the buoyancy of the liquid, and the second is that the plug 30 drives the driving rod 240 to rise relative to the air duct 21 by means of the locking structure when rotating, so that the float 230 rises a certain distance again, thus the float 230 and the sealing ring 220 can be tightly adhered, and the storage device has a better fresh-keeping effect.
