Description of the new type: [Technical field to which the new type belongs] This creation is related to the stopper used to make the inside of the bottle vacuum, especially about a type of stopper that can be easily disassembled and not easy to fall off. [Prior art] The stopper for air extraction is used to plug the opening of the bottle 'and usually has a piston mechanism to extract the air in the bottle to make the inside of the bottle in a vacuum state' to avoid the contents of the bottle Rot. The conventionally available bottle stopper is usually an elastic body with a conical surface. The stopper is provided in the bottle hole, so that the piston mechanism can only extract the air in the bottle 'and after the air in the bottle has been extracted. Keep the vacuum inside the bottle. However, if the elastomer fits too tightly into the bottle hole, it will be difficult for the user to insert the elastomer into the bottle hole and pull it out of the bottle hole; if the elastomer does not fit tightly with the bottle hole, the user will borrow When the air in the bottle is extracted by the piston mechanism, the stopper for extraction can easily fall off. There is also another type of stopper available on the market for sealing. The bottle hole is sealed with a cap made of elastic material. However, the cap is still too tight to be easily disassembled and too loose to fall off easily. . In other words, the bottle stoppers used for air extraction still have their shortcomings, and need to be improved. [New content] In view of the above-mentioned shortcomings, the main purpose of this creation is to provide a stopper that can be evacuated, which can be easily placed in the bottle hole and can be easily disassembled ', and its sealing effect is good and it is not easy to fall off. 3 Μ431872 In order to achieve the above purpose, the design mentioned in this creation includes a first unit, which has a bottle with -cylinder ... recorded phase_section-limit of the unit =, with-and a single set on the professional cylinder _... bottle riding The size of the second unit is to increase the outer diameter of the second unit when it is displaced relative to the stopper of the second unit. The first unit enlarges the bottle hole seal and closes the bottle hole of Shu, so that the bottle hole seal not only achieves the sealing function, but also is not easy to be loosened by the action of the piston. The cylinder sucks air out of the bottle_air. Conversely, as long as the bottle hole seal is no longer pressed against the bottle hole by operating the first unit, the suction-stopperable stopper can be removed easily. The detailed structure, characteristic assembly or use method of the stopper provided by this creation will be described in the detailed description of the subsequent embodiments. However, those with ordinary knowledge in the field of creation should be able to understand that these detailed descriptions and the specific embodiments listed in the implementation of this creation are only used to illustrate this creation and are not intended to limit the scope of patent applications for this creation. [Embodiment] In the following, the technical content and characteristics of this creation will be explained in detail with the enumerated examples and accompanying drawings. Please refer to the first diagram to the third diagram first. The extractable stopper 10 provided by a preferred embodiment of the present invention includes a first unit 20, a piston 30, a bottle hole seal 40, and a second Unit 50, the ventable stopper 10 is used for sealing-9 holes in the bottle. The first unit 20 includes a driving member 22 and a spacer f. The driving member 22 has a screw hole 222. The spacer 24 is ring-shaped and has an abutting portion 242 having a larger outer diameter and a position portion 244 having a smaller outer diameter. The limiting portion 244 can extend into the bottle hole. The piston 30 includes a body 32 and a seal 34 provided thereon. The bottle hole seal 40 is ring-shaped and has an outer peripheral surface 42 which is bent outward to protrude from the protruding portion 44 of the outer peripheral surface 42. The number of the protrusions 44 of the bottle hole seal 40 is not limited. The first single 5G of 5H includes-cylinder 60 and-one-way valve% for external unidirectional exhaust, and the piston 3G can be operated to slide in the gas rainbow of the second material. The gas red 60 has a cylinder 62 and a limiting portion 64 protruding from an outer peripheral surface 622 of the cylinder. The top of the cylinder block 62 is shaped and has a threaded portion 624 '. The bottom of the cylinder block 62 has a perforation 626 (as shown in the fourth figure). As shown in the fifth figure, the one-way valve 70 and the piston 30 are disposed in the cylinder 62, and the piston 30 can slide between the one-way valve 70 and the phantom top of the cylinder; the The check valve 70 has-a valve seat 71 and a valve disc. The valve seat 71 is formed with a plurality of vent grooves 711 ′. The check valve 70 is located at the bottom of the cylinder block 62 to prevent air from entering the cylinder block 62 from the perforation 626. . The bottle hole seal 40 and the spacer 24 are sequentially sleeved on the cylinder block, and the bottle hole seal 40 is located at the stopper portion 244 of the spacer 24 and the stopper portion of the cylinder 60M431872. 64; in other words, the first unit: between the driving member and the bottle hole seal. The driving member ^ is sleeved on the piston 3G and screwed to the threaded portion of the button body 62, and the driving member 22 is abutted against the abutting portion of the spacer μ. A stopper ⑽ can be further provided at the end of the plug 30 located outside the cylinder body 62. 々—The pure weaving 1 () that can be touched by the foregoing capture, -Early 5G and the bottle hole seal 4G can be made into ordinary bottle diameter x inch to easily extend into -Bottle 9〇 Inside, and with the M part of the spacer as abut against the top of the bottle 90. Then, the user can make the direction axis outside the 5G_ hole of the second unit by turning the driving member U (as shown in the figure); in other words, the limit position of the first unit and the position of the second unit The relative displacement of the part is driven by the driving member. At the same time, in the gas rainbow, the position portion 64 will squeeze the bottle hole seal 40 repeatedly to increase its maximum outer diameter (for «° the bottle hole seal is subject to the limit portion of the first unit and the second The limit part of the unit is squeezed to increase its outer diameter.), And then the bottle hole seal 40 $ protruding portion 44 abuts against the bottle hole 90. In this way, the bottle hole seal 40 is sealed. Then, the user pulls the piston 30 outward (as shown in the sixth figure) through the holding member 80, so that the air in the bottle 90 can enter the air passage 711 through the one-way air groove 711. The cylinder 62; the user presses the piston 30 inward (as shown in the seventh figure), so that the air in the cylinder 62 can pass through the gap between the cylinder 62 and the seal 34 and The gap between the driving member 22 and the piston 30 is discharged, and the valve plate 75 is forced to cover the back hole 626 to prevent the air in the cylinder 62 from flowing back into the bottle 90. In this way, M431872, as long as the above action is repeated several times, the inside of the bottle 9q can be in a vacuum state, and the woven hole seal can not be easily loosened by the action of the piston 3G. Erdanfan 50 moved in the direction of the bottle ceremony, so that the bottle hole seal fairy no longer abuts the bottle 90 dekong ', you can taste the easy-to-money bottle stopper 90 bottles. In other words, the stopper 10 that can be reduced can be easily plugged in the bottle hole and can be easily disassembled, and its sealing effect is good and it is not easy to fall off.
