Description

Storage device

Technical Field

The invention belongs to the technical field of liquid storage equipment, and particularly relates to a storage device.

Background

Conventional storage containers for liquids, such as red wine, beverages, oils, are mostly simple containers, for example glass bottles. After a part of liquid is poured out of the container, air enters the container, and the residual liquid in the container is easy to generate oxidation reaction, such as a common red wine bottle, after the red wine bottle is opened, the red wine is easy to be contacted by oxygen in the air and oxidized and deteriorated, and when a part of red wine remains in the red wine bottle, the red wine is easy to be oxidized by the air in the bottle, so that the storage life is short, and the taste is greatly different when the red wine is drunk again.

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

and (3) refrigerating: the wine cabinet has no air isolation, has no practical obvious effect on slowing down oxidation, has the main function of storing wine without opening bottles, and can cause obvious damage to the taste and quality of red wine at an excessively low temperature if the wine cabinet is placed in a refrigerator for refrigeration.

Replacing the bottle after opening the bottle: it is cumbersome to handle and the vial has a fixed volume and cannot be adjusted to the proper size depending on the amount of wine remaining.

And (3) vacuumizing a plug: because the volume of the wine bottle is fixed, the size of the wine bottle can not be adjusted along with the air extraction, a large amount of air still exists in the bottle, and the obvious actual oxidation prevention effect is not achieved.

Filling inert gas into the wine bottle: the operation is complicated, and very expensive professional machines and expensive inert gas consumables are needed, wherein the mode of injecting the inert gas after opening the bottle cannot completely isolate oxygen, only reduces the oxygen content in the bottle and the contact oxygen amount of wine liquid, and the machine equipment has large volume, and the inert gas consumables are expensive and do not have large-scale popularization value; another way of injecting inert gas without opening the bottle needle requires the use of a cork as the raw wine cork, but most of the commercially available wines do not use the cork, the use range of the cork cannot cover most of the commercially available wines, but the equipment is expensive, the consumption of consumables is high, the cost is high, and the operation is complicated.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

As shown in fig. 1 to 3 and 5, the storage device according to the embodiment of the present invention includes a container 10, an adjusting member 20, and a plug 30. The container 10 can be made of transparent or semitransparent materials, and the top end of the container 10 is opened; the top of the container 10 may be provided with a cover 100, the cover 100 may be detachably mounted on the container 10, the cover 100 may be provided with a through hole which is coaxially arranged with the container 10, the liquid contained in the container 10 may be poured out when the cover 100 is detached and the adjusting member 20 is taken out, and the components in the container 10 may be cleaned.

As shown in fig. 3 and 5, the adjusting member 20 includes an air duct 21 and a piston 22, the upper end and the lower end of the air duct 21 are open, the piston 22 is connected to the bottom end of the air duct 21, the top end of the air duct 21 passes through the through hole of the cover 100, and the air duct 21 can drive the piston 22 to move up and down relative to the container 10. 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 packing 220 is in close contact with the inner surface of the container 10. When the air duct 21 carries the piston 22 to move downwards relative to the container 10, a gap is formed between the sealing ring 220 and the float 230, so that air can flow into the air duct 21 through the gap and is discharged from the top opening of the air duct 21.

When the float 230 moves until the bottom surface of the float 230 sufficiently contacts the liquid, the outer peripheral side wall of the float 230 is in close contact with the packing 220; the plug 30 is interlocked with the float 230, and the plug 30 rotates in a predetermined direction to drive the float 230 to ascend. When the floater 230 moves downwards to the state that the floater cannot move downwards any more, the air exhaust is completed, at the moment, the plug 30 is inserted into the opening at the top of the air guide pipe 21, when the plug 30 rotates along the preset direction, the floater 230 is driven by the plug 30 to rise for a certain distance, at the moment, the floater 230 is further clung to the sealing ring 220, and then the gap between the sealing ring 220 and the floater 230 is sealed, so that the external air is difficult to enter the container 10 from the air guide pipe 21 to contact with liquid, the sealing effect is good, the anti-oxidation function of the storage device can be improved, and the preservation time is prolonged.

In the storage device provided by this embodiment, when the air duct 21 drives the piston 22 to move downward 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 be 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 ascends when the air discharge is completed, the gap between the float 230 and the peripheral sealing ring 220 is gradually reduced, after the air discharge is completed, the float 230 and the sealing ring 220 are preliminarily attached, because the plug 30 and the float 230 are linked, the plug 30 is inserted into the air duct 21, and when the plug 30 rotates in a predetermined direction, the float 230 can be driven to ascend, so that the float 230 and the sealing ring 220 can be further attached to each other, thereby isolating the liquid in the container 10 from the air, and preventing external air from entering the container 10 from between the sealing ring 220 and the float 230, thereby slowing down the liquid, and the fresh-keeping time is long.

In one embodiment, as shown in fig. 3 and 5, the driving rod 240 is connected to the top end of the float 230, the driving rod 240 is accommodated in the airway tube 21, the plug 30 forms an interlocking structure with the float 230 through the driving rod 240, the driving rod 240 can be driven to rotate when the plug 30 rotates in a predetermined direction (e.g., the direction of F1 in fig. 5 and 8), and the float 230 can be driven to ascend relative to the airway tube 21 when the driving rod 240 is 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 through the gap between the float 230 and the packing 220, and the liquid in the container 10 can be poured out through the air duct 21 when the container 10 is poured. When the air exhausting operation is performed, the plug 30 can be pulled out, force is applied to the air duct 21, the air duct 21 drives the piston 20 to move downwards, when the floater 230 descends to be in contact with the liquid level to exhaust air, the floater 230 can not descend any more, at the moment, the plug 30 is inserted into the air duct 21, the plug 30 is rotated by a certain angle according to the preset direction, the plug 30 lifts the floater 230 through the driving rod 240, the floater 230 ascends at the same time, and further the peripheral side wall of the floater 230 can be tightly attached 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 predetermined direction, the driving rod 240 is driven to the unlocking position, the driving rod 240 slightly moves downwards relative to the air duct 21, the float 230 is driven to slightly move downwards, the plug 30 is pulled out, the state that the float 230 is further tightly attached to the sealing ring 220 is released, the air duct 21 is 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 the 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 recessed to form a groove 310, and a locking structure is formed between the groove wall of the groove 310 and the driving rod 240. When the air duct 21 drives the piston to move downwards and the float 230 is not in contact with the liquid in the container 10, the driving rod 240 and the float 230 are in a free suspension state, a gap is formed between the peripheral side wall of the float 230 and the sealing ring 220, and air can flow out from the gap in the downward movement process of 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 extends into the groove 310, so that when the plug 30 rotates in a predetermined direction, the driving rod 240 can be driven to rise relative to the air duct 21 through the locking structure, and further, the peripheral side wall of the float 230 is tightly attached to the sealing ring 220. That is to say, the float 230 has twice actions of rising in this process, the first time is that the exhaust rises due to liquid buoyancy, the second time is that the plug 30 drives the driving rod 240 to rise relative to the air duct 21 by virtue of the locking structure when rotating, and then the float 230 rises for a certain distance again, so that the float 230 and the sealing ring 220 can be attached more tightly, and the storage device has a better fresh-keeping effect. The cross-section of both the drive rod 240 and the groove 310 may be provided in a circular shape.
