Referring to FIG. 1, a wine stopper capable of vacuumizing in accordance with an embodiment of the present invention, comprises a base 1 and a shell 2. The base 1 can cover an outside of the wine bottle opening, and the shell 2 is mounted on the base 1 and encloses with the base 1 to form a chamber 3 therebetween. The shell 2 and the base 1 can be connected by means of a snap connection; specifically, a buckle 11 is formed on an outer circular surface of the base 1, and a section of the base 1 with of the buckle 11 is fitted in the shell 2 with the buckle 11 engaged into a slot of the shell 2 to form a detachable connection between the base 1 and the shell 2. A boss 12 is provided at a side of the base 1 away from the shell 2. When the base 1 is placed on a wine bottle, the boss 12 of the base 1 can extend into the bottle opening and tightly fit with an inner wall of the bottle opening. The boss 12 can be covered with a bottle opening silicone sleeve 121 adapted to the bottle opening, and an outer surface of the bottle opening silicone sleeve 121 is provided with threads, thereby, when the boss 12 is inserted into the bottle opening, the bottle opening silicone sleeve 121 is squeezed and deformed to seal the bottle opening. The wine stopper also comprises a power supply and a vacuum pump 31. The power supply and the vacuum pump 31 are both set in the chamber 3. A battery box 32 is also set in the chamber 3, the vacuum pump 31 is mounted in the battery box 32, and has two mounting holes for installing batteries, the power supply can be two AAA batteries, and the two batteries are respectively received in the two mounting holes. The opposite ends of the battery box 32 are provided with battery springs 321 and a battery shrapnel 322, respectively. There are two battery springs 321 respectively corresponding to the two mounting holes; and there is one battery shrapnel 321 with two electrodes thereon respectively corresponding to two. The battery box 32 is also provided with a PCBA 33 therein. A control circuit of the vacuum pump 31 is set on the PCBA 33. The vacuum pump 31 and the power supply are electrically connected to the control circuit. The boss 12 defines a through hole 122 therein. when the boss 12 of the stopper is inserted into the bottle opening, the through hole 122 is in communication with the wine bottle, and the vacuum pump 31 can draw the air in the wine bottle through the through hole 122 and control a vacuum degree in the wine bottle. A measurement assembly 34 is provided in the chamber 3, and the measurement assembly 34 is electrically connected to the vacuum pump 31 through the control circuit. The measurement assembly 34 can be used for detecting a vacuum degree in the wine bottle, thereby achieving the purpose of controlling the operation of the vacuum pump 31. In the present invention, the wine stopper has a function of vacuuming. When the wine stopper is applied to a wine bottle, a vacuum degree in the wine bottle can be detected by the measurement assembly 34, and if the vacuum degree in the wine bottle reaches a preset requirement, the vacuum pump 31 does not work, and if it is detected that the vacuum degree in the bottle does not reach a preset requirement, the vacuum pump 31 starts to extract air in the wine bottle until the vacuum degree reaches the requirement. The whole process is completed automatically, which is more convenient, especially when there is remaining wine in the wine bottle after the wine bottle is opened, the vacuum degree in the wine bottle can be automatically controlled through this wine stopper to ensure the taste of the remaining wine. Generally, the through hole 122 forms a tapered port (tapered hole) away from the shell 2, and a sealing plug is provided in the tapered port. The sealing plug can be a sealing silicone plug 123. When the vacuum degree in the wine bottle reaches a preset vacuum degree, the wine stopper stops vacuuming, and then the sealing silicone plug 123 can be used for sealing the wine bottle and maintain a vacuum degree in the wine bottle. Since the wine bottle is in a relative vacuum state, there will always be a suction force to keep the sealing silicone plug 123 sucked and fitted in the tapered hole 13 of the base 1 with a good sealing.

Referring to FIGS. 1 and 2, specifically, the measurement assembly 34 comprises a silicone plate 341 installed on the base 1 and a first micro-touch switch 342 that controls the on-off of the control circuit of the vacuum pump. The silicone plate 341 and the first micro-touch switches 342 are all set in the chamber 3, and the first micro-touch switch 342 can presses against the silicone plate 341. The base 1 defines a cavity corresponding to the first micro-touch switch 342, and the cavity can communicate with the wine bottle. The silicone plate 341 can seal the cavity at one end thereof towards the chamber 3. In this embodiment, the structure of the measurement assembly 34 uses a micro-touch switch to control the on-off of the control circuit of the vacuum pump 31. The silicone plate 341 has one side corresponding to the wine bottle, and the other opposite side corresponding to the chamber 3. When the plate 341 is pressed against the first micro-touch switch 342, the control circuit becomes connected, thus the vacuum pump 31 start to work to extract air in the wine bottle. During the vacuuming process, an air pressure in the wine bottle gradually decreases, that is, an air pressure onto the side of the silicone plate 341 gradually decreases, while an air pressure onto the other opposite side of the silicone plate 341 remains unchanged, so that the silicone plate 341 is gradually recessed into the cavity of the base 1 under the air pressure onto the side of the silicone plate 341 corresponding to the chamber 3, and a pressing force of the silicone plate 341 on the first micro-touch switch 342 is gradually reduced. When the pressing force of the silicone plate 341 on the first micro-touch switch 342 is reduced to a certain degree or disappears, the first micro-touch switch 342 open the control circuit of the vacuum pump 31, the vacuum pump 31 stops working, and at this time, a vacuum degree in the wine bottle has reached a predetermined vacuum degree.

In another embodiment, a second micro-touch switch 35 is also mounted to the base 1. The second micro-touch switch 35 has a contact 353 which can also control the on-off of the control circuit of the vacuum pump. The second micro-touch switch 35 is electrically connected in series with the first micro-touch switch 342 of the measurement assembly 34. When the wine stopper is engaged with the wine bottle, an end of the bottle opening can press against the contact 353, which make the control circuit connected by means of the contact 353. In this embodiment, the second micro-touch switch 35 and the first micro-touch switch 342 must be closed at the same time to keep the control circuit connected, and one of which is open will make the control circuit disconnected. When the boss 12 of the base 1 is inserted in the bottle opening, an end of the bottle opening is engaged with the contact 353 which makes the second micro-touch switch 35 closed; and the air pressure in the wine bottle is the same as the outside air pressure at this time, which make the first micro-touch switch 342 to maintain a closed state, thereby the vacuum pump 31 starts to work.

For optimizing the above embodiment, the second micro-touch switch 35 comprises a guide post 351 and a switch unit 352. The guide post 351 passes through a channel in the base 1 and can move therein relative to the base 1, and the guide post 351 can press against the switch unit 352 to control the connection or disconnection of the control circuit of the vacuum pump 31. The switch unit 352 is set on the PCBA 33, and the contact 353 is one end of the guide post 351 which extends into channel in the base 1, and the other end of the guide post 351 opposite to the contact 353 can press against the switch unit 352. In this embodiment, an end of the bottle opening can push against the guide post 351 to move linearly, and then the guide post 351 pushes against the switch unit 352, and at this time, the switch unit 352 is in the closed state. When the wine stopper is taken away from the wine bottle, the guide post 351 will fall back and the switch unit 352 will be disconnected; at this time, even if the measurement assembly 34 detects that an air pressure on the side of the bottle opening is higher, the vacuum pump 31 will not work, which can prevent the vacuum pump 31 from malfunctioning. Further, an elastic member 354 can be set to sleeve on the guide post 351, and the guide post 351 is provided with a flange 355 on one end thereof with the contact 353. The elastic member 354 is arranged in the chamber 3, and is set between the switch unit 352 and the flanges 355, The elastic member 354 is usually a return spring. When the guide post 351 pushes against the switch unit 352, the return spring is compressed. When the wine stopper is installed to the wine bottle, the return spring is compressed; if the wine stopper is pulled out from the wine bottle, the return spring pushes the flange 355, and then the flange 355 drives the guide post 351 to move into the base 1, and the switch assembly is disconnected.

Referring to FIG. 2, in another embodiment of the present invention, the wine stopper further comprises an anti-tilt switch 331, and the anti-tilt switch 331 is also connected in series to the control circuit of the vacuum pump 31 and is set on the PCBA 33. The anti-tilt switch 331 can detect a tilt angle of the wine bottle. After the wine stopper is inserted into the bottle opening, if the wine bottle is tilted to a certain angle and the wine stopper continues to vacuum, wine will be drawn out from the wine bottle, which will cause damage to the wine stopper. To avoid the wine stopper from vacuuming at the above possible situations, set a predetermined tilt angle, if the wine bottle with the wine stopper is tilted to the predetermined tilt angle, the wine stopper will automatically stop vacuuming, and the predetermined tilt angle can be less than 20 degrees or less than 45 degrees.

Further, the wine stopper also comprises an indicator light 332, which can be an LED indicator 332. The indicator light 332 is electrically connected to the vacuum pump 31. The indicator light 332 is used to indicating whether the vacuum pump 31 is working. For example, when the vacuum pump 31 is working, the indicator light 332 is blue, and when the vacuum pump 31 stops working, the indicator light 332 is green. A light guide post 21 is mounted at a side of the shell 2 away from the base 1. The indicator light 332 is set in the chamber 3 corresponding to the light guide post 21. The indicator light 332 is also set on the PCBA 33, and the light emitted by the indicator light 332 can be transmitted through the light guide post 21 to for the user to observe, and the indicator light 332 is set inside the shell 2 for protection. In another embodiment, the indicator light 332 is also set in the shell 2, and the shell 2 is light-transmitting. The light-transmitting shell can be made of a transparent or translucent material. Perform electroplating or spraying rubber oil or ordinary oil to treat a surface of the shell 2; and then, engrave with laser on the surface of the shell 2 where corresponds to the indicator light 332, generally at the middle position on the top surface of the shell 2, to form a laser mark indicating the work of the vacuum pump 31. The laser mark can be a pattern or a LOGO. When the LED indicator 332 is illuminated, the surface of the shell 2 will display the laser mark which also acts as a light indicator to indicate that the vacuum pump is working, so as to achieve the same technical effect as the previous embodiment.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
