Vacuum bottle stopper

Abstract

This invention discloses a vacuum bottle stopper, comprising a stopper body, a vacuum pump and a pressure sensing element installed within the stopper body, a stopper body mounted on the stopper body, and a connected suction chamber and ventilation space on the stopper body. The suction chamber has an air hole communicating with the internal space of the bottle, and the ventilation space is connected to the suction pipe of the vacuum pump and the air inlet pipe of the pressure sensing element. The ventilation space includes a first ventilation space and a second ventilation space that are separated from each other. By connecting the suction pipe and the air inlet pipe to the two ventilation spaces one by one through the suction chamber, without using connecting air pipes, the stopper body is inserted into the bottle opening for sealing. The activated vacuum pump draws air out of the bottle through the air hole on the stopper body, and the air enters the suction pipe and the air pipe through the air inlet space, thereby preserving the liquid in the bottle. The pressure sensing element detects the air in the air inlet space to control the vacuum pump to shut down, reducing the volume occupied and effectively preventing air leakage.

Description

Technical Field

[0001] The invention relates to the technical field of fresh-keeping structures, in particular to a vacuum bottle stopper. Background Art

[0002] When the liquid stored in the bottle is not used up, some liquids need to be preserved, otherwise the quality of the liquid will be affected or the liquid will expire and become unusable. A common practice is to plug the bottle mouth with a stopper, but since the bottle has been opened, air has been mixed into the bottle, which is not conducive to the preservation of the liquid, so the bottle will be vacuumed.

[0003] Vacuum bottle stoppers are generally used on the market. Vacuum bottle stoppers are equipped with a vacuum air pump and a pressure detection unit. The vacuum bottle stoppers are provided with a stopper body, and the stopper body is provided with an air extraction channel. The air inlet pipes of the vacuum air pump and the pressure detection unit are connected to the air extraction channel through the connecting air pipe. The stopper body is used to block the bottle mouth, and then the air in the bottle is extracted through the air extraction channel. If the length of the connecting air pipe is too long, the volume of the bottle stopper will increase, and if the length is too short, it may leak during vacuuming, affecting the vacuuming effect. In addition, since the vacuum air pump and the pressure detection unit have a certain volume, there is a certain distance between the two air inlet pipes. If the air inlet pipe is directly inserted into the stopper body, the volume of the stopper body will increase. Summary of the invention
