As mentioned above, when drinking a drink, usually a large-capacity drink cannot be consumed at one time. Even if the stopper such as a stopper/cap can seal the drink, the drink has been opened, and there is a large amount of air inside the drink bottle. Therefore, unspent drinks are very susceptible to deterioration or affect the next time you drink. At present, low-temperature refrigeration is often used, and the use of such a method cannot remove the air in the beverage bottle, and the oxidation rate of the beverage can be slowed down to a small extent.

Accordingly, some embodiments of the present disclosure provide an evacuated freshness retaining device that is capable of automatically performing vacuum preservation at least after being placed in a beverage bottle or, in some embodiments, for beverage bottles of different heights. The beverage bottle referred to in some embodiments of the present disclosure may be a beverage bottle that does not undergo an observable deformation after being stressed, such as a glass bottle, a porcelain bottle, a plexiglass bottle, or the like.
