The cap body is provided with a column body, an air inlet channel is arranged inside the column body, an air outlet is arranged at the lower end of the air inlet channel, and a one-way valve assembly is arranged between the air outlet and the lower cover. The flow direction of the one-way valve assembly is from the air inlet channel to the lower cover.

[0005] Preferably, the one-way valve assembly includes a sealing gasket, a pressing plate, and a spring arranged in sequence from top to bottom. The lower end of the spring abuts against the lower cover, and the upper end abuts against the pressing plate. The sealing gasket is abutted against the air outlet through the pressing plate to form a seal.

[0006] Preferably, an installation seat for installing the spring is arranged on the bottom surface of the pressing plate.

[0007] Preferably, a guiding part is arranged on the cap body around the pressing plate.

A supporting part is arranged on the upper surface of the lower cover. During assembly, the connecting columns pass through the connecting holes, and the supporting part abuts against the cap body. The lower cover and the cap body are fixedly connected by hot-pressing the ends of the connecting columns.

[0009] An electric carbonated beverage fresh-keeping component includes the bottle cap according to any one of the above, and further includes an air pump component. The air pump component is provided with an air outlet pipe that cooperates with the air inlet channel.

[0010] Preferably, a second sealing ring is provided on the outer wall of the air outlet pipe.

[0011] Advantages of the present utility model: The cooperation between the bottle cap and the air pump of the present utility model directly inflates the beverage bottle through the air pump, increasing the air pressure inside the bottle, so that the carbon dioxide in the soda water no longer escapes, having the effect of preserving the freshness of the soda water, and saving time and effort compared with manual pressurization.

[0018] As Figures 1-5 shown, a bottle cap includes a cap body 1. The cap body 1 is provided with a thread 101 for connecting to the mouth of the beverage bottle. A first sealing ring 2 is provided inside the cap body 1. When the cap body 1 is tightened, the first sealing ring 2 seals the mouth of the beverage bottle. The lower end of the cap body 1 is fixedly connected to a lower cover 3. The cap body 1 is provided with a cylinder 102. An air inlet channel 103 is provided inside the cylinder 102. An air outlet 105 is provided below the air inlet channel 103. A one-way valve assembly is provided between the air outlet 105 and the lower cover 3. The flow direction of the one-way valve assembly is from the air inlet channel 103 to the lower cover 3.

[0019] The one-way valve assembly includes a sealing gasket 4, a pressing plate 5, and a spring 6 arranged in sequence from top to bottom. The lower end of the spring 6 abuts against the lower cover 3, and the upper end abuts against the pressing plate 5. The sealing gasket 4 is pressed against the air outlet 105 by the pressing plate 5 to form a seal.
