[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this invention pertains; the terms used in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit this invention; the terms "including" and "having" and any variations thereof in the specification and claims of this invention and the accompanying drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" and the like in the specification and claims of this invention and the accompanying drawings are used to distinguish different objects, not to describe a specific order.

[0026] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figure 1-3 The following are examples provided by the present invention.

[0029] The embodiment of the present utility model provides a bottle sealing device, comprising: a water injector 10, a sealing valve 20, a conduit 30 and a water bag 40. The water injector 10 is directly connected to the sealing valve 20, or can be connected through the conduit 30. The conduit 30 is a hose, which is convenient for connection and layout. The sealing valve 20 is connected to the water bag 40 through the conduit 30, which makes it convenient to put the water bag 40 into the bottle while leaving the sealing valve 20 outside the bottle. The water injector 10 is used to inject liquid into the water bag 40. The liquid is generally water. The water bag 40 is an expandable and contractible elastic sphere, similar to a balloon. The size of the water bag 40 changes with the volume of the injected liquid. When the water bag 40 is not filled with liquid, the water bag 40 is in a deflated state and can easily enter the interior of the bottle through the mouth of a general bottle. Then, as liquid is continuously injected into the water bag 40, the volume of the water bag 40 gradually increases, becomes round, and finally abuts tightly against the inner wall of the bottle. As the liquid pressure in the water bag 40 continues to increase, the connection between the outer wall of the water bag 40 and the inner wall of the bottle becomes tighter, thereby isolating the objects originally contained in the bottle from the outside air, thereby achieving a good sealing effect. Compared with the airbag cork, the water bag 40 filled with liquid can exert greater pressure on the inner wall of the bottle and has a better sealing effect. In addition, the sealing valve 20 is in an open state during the process of the water injector 10 injecting water into the water bag 40, so that the liquid can smoothly enter the water bag 40. When the liquid in the water bag 40 is filled to a sufficient volume, the sealing valve 20 is closed. At this time, the sealing valve 20 can be used to seal the water bag 40, so that the liquid in the water bag 40 will not leak out, keeping the volume of the liquid in the water bag 40 fixed, and maintaining the size of the water bag 40. When the water bag 40 needs to be taken out, stop injecting water first, and then open the sealing valve 20. The water in the water bag 40 will be squeezed out under the elastic force of the water bag 40, and finally the water bag 40 that has shrunk to a certain size or shrunk can be taken out from the bottle mouth of the bottle.

[0030] Furthermore, the water injector 10 is detachably connected to the sealing valve 20. After the bottle is sealed with the water bag 40, the sealing valve 20 is closed first, and then the water injector 10 can be removed, which makes it more convenient to place the bottle and reduces the storage space occupied by the entire sealing device.

[0031] Furthermore, the sealing valve 20 is a one-way throttle valve, the conducting interface of the sealing valve 20 is connected to the water injector 10, and the throttling port of the sealing valve 20 is connected to the conduit 30, so that the liquid can enter the water bag 40 normally from the water injector 10, and cannot easily leak from the water bag 40. It can avoid or reduce the backflow of liquid that has been injected into the water bag 40 when the water injector 10 stops injecting water, and the volume of the water bag 40 is reduced, so that the sealing effect is worse.

[0032] Specifically, the water bag 40 is made of food-grade silicone, which is safer even when it comes into contact with objects stored in the bottle.

[0033] Furthermore, a dust cover 31 is provided on the sliding sleeve of the hose, and the dust cover 31 is used to cover the bottle mouth of the bottle. The dust cover 31 is made of elastic material and can be changed in size by stretching, so as to facilitate connection with bottle mouths of different diameters and prevent dust from falling into the bottle.

[0034] Specifically, in one embodiment, please refer to the attached Figure 1-2 As shown, the water injector 10 includes a water gun 11 and a water tank 12. The water gun 11 is connected to the water tank 12. The water outlet of the water tank 12 is connected to the sealing valve 20. The water gun 11 is a common water injection device, and its principle is similar to that of a toy water gun. The water gun 11 is provided with a trigger 111 for controlling the water discharge. Pulling the trigger 111 can make the water gun 11 discharge water. The water tank 12 is used to store liquid. The water tank 12 is provided with a detachable sealing cover 121 to facilitate the replenishment of liquid into the water tank 12.

[0035] Specifically, in another specific embodiment, please refer to the attached Figure 3 As shown, the water injector 10 is directly selected as a pump-type pressure head bottle, including a pump head 13 and a water storage bottle 14. The water outlet end of the pump head 13 can be connected to the sealing valve 20 through a hose, and the water-drawing end of the pump head 13 extends into the water storage bottle 14. By pressing the pump head 13, the liquid in the water storage bottle 14 can be drawn out and pumped into the water bag 40 through the catheter 30. It is quick and convenient to use, and the pump-type pressure head bottle is a common commodity currently available, with low cost and easy acquisition.

[0036] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
