[0028] To make the objectives, features, and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described below are merely for explaining this utility model and are not intended to limit it. Furthermore, descriptions of identical or similar components in different embodiments, as well as descriptions of components, features, effects, etc., belonging to the prior art, may be omitted.

[0029] Furthermore, for ease of description, only the parts relevant to this invention are shown in the accompanying drawings, not the entire structure. Also, the same or similar reference numerals may be used in the drawings to refer to the same or similar components in different embodiments.

[0030] Reference Figures 1 to 6This utility model embodiment provides a needle guide 10 replacement unit 20 and a liquid collection device 1 including the needle guide 10.

[0031] Specifically, the liquid extraction device 1 is used to extract liquid from a container 30. The container 30 includes a container opening 31 and a stopper 32 disposed at the container opening 31. A needle guide 10 is adapted to be installed in the liquid extraction device 1 and is equipped with a liquid extraction needle 11. The liquid extraction needle 11 is adapted to pierce the stopper 32 and extract the liquid from the container 30.

[0032] In some embodiments, the liquid extraction device 1 may include a wine extractor and is adapted to extract wine from a wine bottle using a liquid extraction needle 11.

[0033] In some embodiments, the needle guide 10 is also equipped with an inflatable needle 12 adapted to pierce the plug 32.

[0034] In a specific implementation, the inflation needle 12 and the liquid collection needle 11 each have a hollow inflation needle chamber 121 and a liquid collection needle chamber 111, respectively. The inflation needle 12 is adapted to introduce gas into the container 30 through the inflation needle chamber 121 after piercing the stopper 32; the liquid collection needle 11 is adapted to extract the liquid from the container 30 through the liquid collection needle chamber 111 after piercing the stopper 32.

[0035] Specifically, when gas is introduced into container 30 through inflation needle 12, the gas pressure inside container 30 gradually increases. When the gas pressure inside container 30 is greater than the gas pressure outside, under the action of the pressure difference between the inside and outside, the liquid inside container 30 will flow out through the liquid collection needle chamber 111 of liquid collection needle 11, thereby extracting the liquid from container 30.

[0036] In a specific implementation, the liquid collection needle 11 also includes a liquid collection needle inlet 112 and a liquid collection needle outlet 113, which are respectively connected to the liquid collection needle chamber 111, to receive and output liquid respectively. The inflation needle 12 also includes an inflation needle inlet 122 and an inflation needle outlet 123, which are respectively connected to the inflation needle chamber 121, to receive and output gas respectively.

[0037] In some embodiments, the tips of the front ends of the inflation needle 12 and the liquid collection needle 11 can be tapered to facilitate piercing the plug 32.

[0038] In some embodiments, the liquid extraction device 1 further includes a gas cylinder 40 adapted to hold gas and connected to an inflation needle 12, so as to introduce gas into the container 30 through the inflation needle 12.

[0039] In practice, a valve is provided between the gas cylinder 40 and the inflation needle 12, and the gas flow between the gas cylinder 40 and the inflation needle 12 is controlled by opening and closing the valve.

[0040] In some embodiments, the liquid in container 30 may oxidize and deteriorate. In this case, the gas in cylinder 40 can be an inert gas. Introducing an inert gas into container 30 can prevent liquid oxidation and help maintain the original quality of the liquid.

[0041] In some embodiments, the liquid in container 30 can be wine, and the inert gas can be argon. The introduction of argon into container 30 can prevent the wine from oxidizing, thus helping to preserve its freshness for longer.

[0042] As mentioned above, both the liquid collection needle 11 and the inflation needle 12 are mounted on the needle guide 10.

[0043] In some embodiments, the needle guide 10 has a liquid-taking needle mounting groove 101 and an inflation needle mounting groove 102 corresponding to the liquid-taking needle 11 and the inflation needle 12, respectively, to fix the liquid-taking needle 11 and the inflation needle 12 in place.

[0044] In specific implementations, both the liquid collection needle mounting groove 101 and the air inflation needle mounting groove 102 can be implemented using any known technical means in the art, and no limitation is made here.

[0045] In some embodiments, the sip needle 11 and the inflation needle 12 are respectively adapted to be tightly embedded in the sip needle mounting groove 101 and the inflation needle mounting groove 102 to be fixed to the needle guide 10, and to be pulled directly out from the sip needle mounting groove 101 and the inflation needle mounting groove 102 to be removed from the needle guide 10.

[0046] In some embodiments, the liquid collection needle 11 and the inflation needle 12 can also be installed and removed from the needle guide 10 using any other known technical means in the prior art, which are not limited here.

[0047] In this embodiment of the utility model, in order to facilitate the installation and disassembly of the liquid collection needle 11 and the inflation needle 12 relative to the liquid collection device 1, the installation and disassembly of the needle guide 10 relative to the liquid collection device 1 can be achieved.

[0048] Specifically, the liquid collection needle 11 and the inflation needle 12 can be installed on the needle guide 10 first, and then the needle guide 10 can be installed on the liquid collection device 1. When it is necessary to replace the liquid collection needle 11 and / or the inflation needle 12, the needle guide 10 should be removed from the liquid collection device 1 first, and then the liquid collection needle 11 and / or the inflation needle 12 should be removed from the needle guide 10 and replaced.

[0049] To facilitate the replacement of the needle guide 10 with respect to the liquid collection device 1, this embodiment of the invention also provides a replacement unit 20.

[0050] Specifically, the replacement unit 20 includes a base 21 and a limiting member 22. The base 21 is mounted on the liquid dispensing device 1 and has a first base chamber 211 and a second base chamber 212 arranged sequentially from the inside to the outside. The limiting member 22 is disposed in the second base chamber 212 and has a cutout 221 to allow the needle guide 10 to pass through and be fixed in the first base chamber 211.

[0051] In a specific implementation, the limiting member 22 is adapted to rotate so that the hollow part 221 is misaligned with the needle guide 10, thereby restricting the needle guide 10 from passing through the hollow part 221 and leaving the first base chamber 211; the limiting member 22 is also adapted to rotate in the opposite direction so that its hollow part 221 corresponds with the needle guide 10, thereby allowing the needle guide 10 to pass through the hollow part 221 and leave the first base chamber 211.

[0052] In a specific implementation, the limiting member 22 is located outside the needle guide 10 to restrict the needle guide 10 from passing through the hollowed-out portion 221 and leaving the first base chamber 211 from the outside.

[0053] In some embodiments, the base 21 further includes a slot 213 located on its side and communicating with the second base chamber 212. Accordingly, the replacement unit 20 also includes an actuating member 23 adapted to pass through the slot 213 and connect with the limiting member 22.

[0054] In some embodiments, two slots 213 are symmetrically arranged. Correspondingly, two toggle members 23 are also provided.

[0055] In some embodiments, the actuating member 23 and the limiting member 22 may be connected by screws.

[0056] In practice, the actuating member 23 is adapted to move along the slot 213 to drive the limiting member 22 to rotate.

[0057] In some embodiments, the toggle member 23 is adapted to be manually toggle to move along the slot 213, thereby driving the stop member 22 to rotate.

[0058] In some embodiments, the cross-section of the limiting member 22 is a centrally symmetrical shape. Accordingly, the limiting member 22 is adapted to rotate about its center of symmetry.

[0059] In some embodiments, the slot 213 of the base 21 can be an arc-shaped slot, so that the actuating member 23 is adapted to move along the arc-shaped slot 213, thereby driving the limiting member 22 to rotate.

[0060] In some embodiments, the cutout portion 221 of the limiting member 22 has a shape adapted to the needle guide 10 so that the needle guide 10 is adapted to pass exactly through the cutout portion 221.

[0061] In some embodiments, the first base chamber 211 also has a shape adapted to the needle guide 10 so that the needle guide 10 is adapted to be tightly embedded in the first base chamber 211 and fixed thereto.

[0062] In some embodiments, the needle guide 10 has a guide ear 103. Correspondingly, the cutout portion 221 of the limiting member 22 also has a cutout ear 222 corresponding to the needle guide ear 103. When the needle guide 10 passes through the cutout portion 221 of the limiting member 22, the needle guide ear 103 also passes through the cutout ear 222.

[0063] Furthermore, the first base chamber 211 also has a chamber ear 214 corresponding to the needle guide ear 103. When the needle guide 10 is fixed in the first base chamber 211, the needle guide ear 103 is accommodated in the chamber ear 214.

[0064] In some embodiments, two guide ears 103 are symmetrically arranged. Correspondingly, two hollow ears 222 and two chamber ears 214 are also symmetrically arranged.

[0065] When the needle guide 10 needs to be installed in the first base chamber 211, the needle guide ear 103, the hollow ear 222, and the chamber ear 214 correspond in sequence so that the needle guide 10 is suitable to pass through the hollow part 221 and be fixed in the first base chamber 211.

[0066] After the needle guide 10 is fixed in the first base chamber 211, the actuating member 23 moves along the slot 213 to drive the limiting member 22 to rotate, thereby causing the hollow part 221 and the hollow ear 222 of the limiting member 22 to rotate relative to the needle guide 10 and the needle guide ear 103, and causing the hollow ear 222 to be misaligned with the needle guide ear 103, thereby restricting the needle guide 10 from passing through the hollow part 221 of the limiting member 22 and leaving the first base chamber 211.

[0067] When it is necessary to disassemble the needle guide 10, the toggle member 23 can be moved in the opposite direction to drive the limiting member 22 to rotate in the opposite direction, so that the hollow ear 222 of the limiting member 22 corresponds to the needle guide ear 103 again, thereby making the needle guide 10 suitable to pass through the hollow part 221 of the limiting member 22 and leave the first base chamber 211.
