[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0056] In the description of this utility model, it should be noted that the terms "center," "front," "rear," "upper," "lower," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0057] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a wine preservation device 100, which includes a gas supply component 10, a gas filling component 40, a control valve 20, a gas pipe 50 connecting the gas supply component 10 and the gas filling component 40, a winding component 30 for housing the gas pipe 50, and a housing 60. The gas supply component 10 may contain gas. The gas filling component 40 is used to deliver the gas flowing from the gas supply component 10 to a wine container holding the wine product. The control valve 20 can be used to control the opening and closing of the gas pipe 50, that is, the control valve 20 can control the opening and closing of the gas path between the gas filling component 40 and the gas supply component 10. The gas supply component 10 and the gas filling component 40 are connected to the housing 60.

[0058] Specifically, the wine preservation device 100 further includes an equipment chamber 62 disposed within the housing 60 and an operating area 63 located outside the housing 60. The equipment chamber 62 contains a gas supply area 621 and an inflation area 622. The gas supply component 10 is disposed in the gas supply area 621, and the inflation component 40 and the winding component 30 are disposed in the inflation area 622. The inflation component 40 is exposed in the operating area 63. Furthermore, the control valve 20 is disposed in the operating area 63, allowing the user to easily control the opening and closing of the control valve 20.

[0059] Furthermore, the inflation area 622 is also provided with a placement part 623 for placing the inflation component 40 and an air tube placement part 624 for accommodating the air tube 50, and the placement part 623 is disposed near the operation area 63 relative to the air tube placement part 624. The inflation component 40 may be disposed in the placement part 623, and the winding assembly 30 may be disposed in the air tube placement part 624.

[0060] In this embodiment, the equipment room 62 is further provided with a gas storage area 625 and a placement rack 6251 located in the gas storage area 625. The placement rack 6251 is provided with at least one storage slot 6252 for placing gas cylinders 13. The storage slot 6252 can hold excess gas cylinders 13, which can effectively reduce downtime caused by replacing gas cylinders 13, thereby achieving a better gas supply effect. In this embodiment, two storage slots 6252 may be provided.

[0061] Optionally, the gas storage area 625 is located at the bottom of the housing 60, which makes the gas cylinder 13 more stable and facilitates the user to pick up and put down the gas cylinder 13.

[0062] In this embodiment, the equipment room 62 is also provided with a bottle stopper placement area 626, which is provided with a placement slot 6261 for placing bottle stoppers. The placement slot 6261 can store bottle stoppers for user convenience.

[0063] Furthermore, the housing 60 also includes a door 80 for opening and closing the equipment chamber 62, and the bottle stopper placement area 626 is located on the side of the door 80 facing the equipment chamber 62, so that the bottle stopper can be placed inside the equipment chamber 62 to avoid contamination of the bottle stopper.

[0064] The aforementioned alcoholic beverage preservation device 100 can fill the wine container with gas to prevent the alcoholic beverage inside the container from coming into contact with air, thereby preventing the alcoholic beverage from oxidizing and affecting the taste. Furthermore, the alcoholic beverage preservation device 100 has a modular design, a compact structure, and is easy to use.

[0065] like Figure 3 and Figure 4 As shown, the gas supply assembly 10 includes a gas supply bracket 11, an insertion pin 12 fixedly disposed relative to the gas supply bracket 11, and a gas cylinder 13 defining a gas chamber 131. The insertion pin 12 is used to insert into the gas cylinder 13 to release the gas inside the gas cylinder 13, so that the gas flows into the wine container through the filling assembly 40. The gas supply assembly 10 can be configured with multiple gas cylinders 13, and when it is necessary to replace a gas cylinder 13, a prepared gas cylinder 13 can be directly replaced. Of course, in some embodiments, the gas supply assembly 10 can also supply gas through a device such as an air pump.

[0066] Furthermore, the gas supply bracket 11 can be fixedly mounted relative to the housing 60. It is conceivable that the gas supply bracket 11 can be fixed to the housing 60 via threaded structures, snap-fit ​​structures, or other connection methods, facilitating assembly.

[0067] Optionally, the gas supply component 10 is equipped with an inert gas, such as argon, to isolate the alcoholic beverage inside the container from the air, thereby extending the storage time of the alcoholic beverage and ensuring its storage quality. The alcoholic beverage can be liquid wine.

[0068] In this embodiment, the gas supply assembly 10 further includes a fixing part 141 and a sleeve 142 connected to the fixing part 141. The fixing part 141 can be connected to the gas supply bracket 11, and the insertion needle 12 is disposed on the side of the fixing part 141 facing the sleeve 142. Furthermore, the fixing part 141 and the sleeve 142 together define a receiving cavity 143 for accommodating the gas cylinder 13, and the insertion needle 12 is located within the receiving cavity 143.

[0069] Furthermore, the fixing part 141 can be fixedly disposed relative to the gas supply bracket 11. Specifically, the gas supply assembly 10 also includes a connecting frame 16 connecting the fixing part 141 and the gas supply bracket 11. The outer periphery of the fixing part 141 is columnar, and the connecting frame 16 has a large end 161 and a small end 162 disposed opposite to each other. The large end 161 is provided with a through hole 163 for the fixing part 141 to pass through. The arrangement of the large end 161 and the small end 162 can make the fixing part 141 more securely installed, and prevent the weight of the gas cylinder 13 from affecting the stability of the gas supply assembly 10 relative to the housing 60.

[0070] In this embodiment, the fixing part 141 and the sleeve 142 can be configured as a threaded connection. During the installation of the gas cylinder 13, the gas cylinder 13 is placed inside the sleeve 142, and then the sleeve 142 is rotated to make the sleeve 142 and the fixing part 141 securely connected, and the insertion needle 12 is inserted into the gas cylinder 13 through the bottle mouth 132 to release the gas in the gas cylinder 13. The arrangement of the receiving cavity 143 not only avoids the insertion needle 12 from being unable to be fixedly inserted into the gas cylinder 13 due to the high pressure inside the gas cylinder 13, but also prevents gas leakage. Of course, the fixing part 141 and the sleeve 142 can also be configured as a snap-fit ​​connection. In addition, in some embodiments, the gas cylinder 13 can also be directly fixed to the fixing part 141.

[0071] In this embodiment, the gas supply assembly 10 further includes a sealing gasket 151, which has a through hole through which the insertion needle 12 passes. The sealing gasket 151 can be installed to the outside of the insertion needle 12 through the through hole. The sealing gasket 151 can seal the gap between the outside of the insertion needle 12 and the mouth 132 of the gas cylinder 13, preventing gas from leaking from the gap between the insertion needle 12 and the mouth 132 of the gas cylinder 13.

[0072] Furthermore, the gas supply assembly 10 also includes an insert elastic element 152. During the insertion of the insertion needle 12 into the gas cylinder 13, the gas cylinder 13 can push against the sealing gasket 151 and move along the insertion needle 12, increasing the deformation of the insert elastic element 152. Specifically, during the insertion of the insertion needle 12 into the gas cylinder 13, the deformation of the insert elastic element 152 gradually increases. Under the action of the deformation force of the insert elastic element 152, the connection between the sealing gasket 151 and the cylinder opening 132 can be made tighter, preventing gas leakage and improving sealing performance.

[0073] In this embodiment, the control valve 20 can be located between the insertion needle 12 and the inflation assembly 40, and the control valve 20 can be configured as a pressure reducing valve 21. Additionally, the wine preservation device 100 also includes a switch 22 for controlling the opening of the control valve 20. The switch 22 controls the pressure reducing valve 21 to operate, thereby connecting the air passage between the insertion needle 12 and the inflation assembly 40. Optionally, the switch 22 can be located on the front side of the housing 60 for convenient user operation, such as... Figure 24 As shown.

[0074] like Figure 2 , Figures 5 to 8 As shown, the winding assembly 30 includes a base 31 and a rotating wheel 32 rotatably disposed relative to the base 31. The air tube 50 is at least partially wound around the rotating wheel 32, and one end of the air tube 50 connected to the inflation assembly 40 can be configured as a pull-out end 52. That is, the air tube 50 between the air supply assembly 10 and the inflation assembly 40 can be partially wound around the rotating wheel 32. During the operation of the winding assembly 30, the user can pull the pull-out end 52 out of the rotating wheel 32 to adjust the pull-out length of the pull-out end 52 for user convenience.

[0075] Specifically, the base 31 includes a first side plate 312 and a second side plate 313 disposed opposite to each other, and a connecting rod 314 connecting the first side plate 312 and the second side plate 313. The rotating wheel 32 is rotatably mounted between the first side plate 312 and the second side plate 313. The connecting rod 314 can limit the air tube 50 from winding around the rotating wheel 32, and can prevent the air tube 50 from detaching from the rotating wheel 32.

[0076] In this embodiment, the alcoholic beverage preservation device 100 further includes a conversion connector 33 disposed on the base 31. The conversion connector 33 may be located on the rotation axis of the rotating wheel 32. The air pipe 50 has a connection end 51 connected to the conversion connector 33, and the rotating wheel 32 is provided with a wire hole 323 for the connection end 51 to pass through.

[0077] Furthermore, the adapter 33 is fixed to the base 31. One end of the adapter 33 can be connected to the control valve 20, and the other end of the adapter 33 can be connected to the connecting end 51. The end of the adapter 33 connected to the control valve 20 can be fixed relative to the base 31, and the end of the adapter 33 connected to the connecting end 51 can rotate synchronously with the rotating wheel 32, thereby ensuring that the rotating wheel 32 can rotate stably and preventing the connection between the connecting end 51 and the control valve 20 from breaking during the rotation of the rotating wheel 32.

[0078] Furthermore, the rotating wheel 32 includes a first wheel 321 and a second wheel 322 disposed opposite to each other, and a wire-passing hole 323 may be provided between the first wheel 321 and the second wheel 322. That is, the connecting end 51 can pass through the wire-passing hole 323 and be disposed inside the rotating wheel 32, and the air tube 50 is wound around the outer periphery of the rotating wheel 32. The first wheel 321 and the second wheel 322 can be connected by means of a threaded structure, a snap-fit ​​structure, etc. In this embodiment, the first wheel 321 and the second wheel 322 are connected by a threaded structure.

[0079] In this embodiment, the winding assembly 30 further includes a coil spring 34, with its two ends acting on the base 31 and the rotating wheel 32, respectively. During the extraction of the air tube 50, the rotating wheel 32 rotates relative to the base 31, increasing the deformation of the coil spring 34. After the extracted end 52 of the air tube 50 is released, under the deformation-restoring force of the coil spring 34, the rotating wheel 32 can rotate relative to the base 31, thereby retracting the air tube 50 into the rotating wheel 32, thus achieving convenient storage of the air tube 50. Of course, in some embodiments, the rotating wheel 32 can also be driven by a motor or other driving component.

[0080] When the pull-out end 52 is pulled out, the rotation direction of the rotating wheel 32 is set to the first direction M, and the direction in which the coil spring 34 drives the rotating wheel 32 to move is the second direction N, and the first direction M and the second direction N are opposite.

[0081] Furthermore, the coil spring 34 is disposed on the side of the first side plate 312 opposite to the rotating wheel 32. The base 31 is also provided with a spring magazine 315 for accommodating the coil spring 34. The spring magazine 315 has a placement opening 3151, a shaft hole 3152 through which the rotating shaft 324 of the rotating wheel 32 passes, and a fixing groove 3153 for fixing the end of the coil spring 34. The rotating shaft 324 of the rotating wheel 32 is provided with a spring groove 3241 for engaging the coil spring 34. One end of the coil spring 34 can be fixed to the fixing groove 3153, and the other end of the coil spring 34 can be fixed to the spring groove 3241, thereby fixing the coil spring 34.

[0082] Furthermore, the winding assembly 30 also includes a cover 35 that covers the placement opening 3151, thereby preventing the coil spring 34 from falling out of the spring chamber 315 and also preventing the coil spring 34 from being exposed and affecting the product appearance.

[0083] like Figures 7 to 10 As shown, the winding assembly 30 further includes a movable member 36 that is movably disposed along the radial direction of the rotating wheel 32. The movable member 36 is provided with a protrusion 361, and the base 31 or the rotating wheel 32 is provided with a guide groove 37 for the movement of the protrusion 361. During the movement of the protrusion 361 along the guide groove 37, the movable member 36 can move relative to the rotating wheel 32 in its radial direction.

[0084] Specifically, one of the base 31 and the rotating wheel 32 is provided with a guide groove 37, and the other of the base 31 and the rotating wheel 32 is provided with a sliding groove 325 for the movable member 36 to move radially along the rotating wheel 32. During the movement of the protrusion 361 along the guide groove 37, the movable member 36 can move relative to the rotating wheel 32 along the sliding groove 325. In this embodiment, the guide groove 37 is provided on the base 31, and the sliding groove 325 is provided on the rotating wheel 32.

[0085] Furthermore, the slide groove 325 and the guide groove 37 are arranged opposite to each other. The slide groove 325 is located on the side of the rotating wheel 32 facing the base 31. Optionally, the guide groove 37 is located on the first side plate 312, and the slide groove 325 is located on the side of the rotating wheel 32 opposite to the first side plate 312.

[0086] Furthermore, the movable part 36 has a hollow structure to reduce the friction between the movable part 36 and the slide groove 325, thereby ensuring the smoothness of the movement of the movable part 36 within the slide groove 325.

[0087] In this embodiment, the guide groove 37 also has a resting part 3731. During the rotation of the rotating wheel 32, when the protrusion 361 moves along the guide groove 37 to the resting part 3731, the extraction end 52 of the air tube 50 is fixed to a predetermined extraction length. Specifically, during the use of the winding assembly 30, the coil spring 34 can drive the rotating wheel 32 to rotate around the second direction N, so that the protrusion 361 is restricted to the resting part 3731, thereby fixing the extraction end 52 of the air tube 50 to a predetermined extraction length, thus facilitating user use.

[0088] Further, the guide groove 37 includes an inner channel 371, an outer channel 372, a locking channel 373, and a connecting channel 374. The inner channel 371 and the outer channel 372 are arranged sequentially outward from the rotation axis of the rotating wheel 32. The two ends of the locking channel 373 are connected to the outer channel 372 and the inner channel 371, respectively, and the two ends of the connecting channel 374 are connected to the outer channel 372 and the inner channel 371, respectively. The resting part 3731 is located in the locking channel 373. When the coil spring 34 drives the rotating wheel 32 to rotate, the protrusion 361 can move from the inner channel 371 through the locking channel 373 to the resting part 3731, thereby restricting the extraction end 52 to a predetermined extraction length.

[0089] Optionally, the docking part 3731 may be configured as a notch formed by an inward recess from the inner wall of the locking channel 373, thereby conveniently restricting the movement of the protrusion 361 and fixing the extraction end 52 to a predetermined extraction length.

[0090] like Figure 10 As shown, the connecting channel 374 has a head end and a tail end disposed opposite to each other. The head end is disposed near the outer channel 372, and the tail end is located within the inner channel 371. The winding assembly 30 also includes an abutment portion 3721 located within the outer channel 372 and a stop portion 3741 disposed at the head end. The distance from the abutment portion 3721 to the rotation axis of the rotating wheel 32 is L1, and the distance from the stop portion 3741 to the rotation axis of the rotating wheel 32 is L2, where L1 is less than L2.

[0091] The abutment portion 3721, the stop portion 3741, and the locking channel 373 are sequentially arranged along the first direction M. During the movement of the protrusion 361 within the guide groove 37, the abutment portion 3721 and the stop portion 3741 guide the movement of the protrusion 361, allowing it to move from the outer channel 372 through the connecting channel 374 into the inner channel 371.

[0092] Figures 11 to 14The diagram illustrates the actuation process of the protrusion 361 within the guide groove 37 under four different conditions. A1-A6, B1-B7, C1-C8, and D1-D6 are schematic diagrams showing the protrusion 361 at different positions within the guide groove 37. The protrusion 361 has a first initial position located in the inner channel 371, a second initial position located in the outer channel 372, and a docking position located in the docking part 3731. The first initial position and the second initial position are correspondingly set, meaning that both the first initial position and the second initial position are at the same angle to the rotation axis of the rotating wheel 32. Figure 11 Figure A1 shows a schematic diagram of the protrusion 361 in the first initial position shown. Figure 11 Figure A6 shows a schematic diagram of the protrusion 361 in the docked position. Figure 12 Figure B7 shows a schematic diagram of the protrusion 361 in the second initial position.

[0093] Figure 11 The diagram illustrates the movement of the protrusion 361 from its initial position to its resting position. During use of the winding assembly 30, the angle by which the pull-out end 52 drives the rotating wheel 32 to rotate is β. If β is greater than 360 degrees, the number of rotations of the rotating wheel 32 driven by the pull-out end 52 is greater than 1. The movement of the protrusion 361 within the guide groove 37 is as follows: Figure 11 As shown. The pull-out end 52 can drive the rotating wheel 32 to rotate around the first direction M, so that the protrusion 361 of the movable member 36 moves along the guide groove 37. After the pull-out end 52 reaches the predetermined pull-out length, the pull-out end 52 can be released. Then, under the action of the coil spring 34, the coil spring 34 drives the rotating wheel 32 to rotate around the second direction N, so that the protrusion 361 is restricted to the stopping position, thereby fixing the pull-out end 52 to the predetermined pull-out length.

[0094] Figure 12 The diagram illustrates the movement of the protrusion 361 from the resting position to the second initial position. When the protrusion 361 is in the resting position, the user needs to return the extraction end 52 to its initial position, that is, to wind the air tube 50 around the rotating wheel 32. Specifically, the user can pull the extraction end 52, causing the rotating wheel 32 to rotate around the first direction M, thereby moving the protrusion 361 from the resting part 3731 to the outer channel 372. At this moment, the extraction end 52 can be released, and the coil spring 34 drives the protrusion 361 to rotate within the outer channel 372 until the elastic deformation of the coil spring 34 is restored, causing the protrusion 361 to stop at the second initial position. At this time, the extraction end 52 returns to its initial extraction length.

[0095] Figure 13The diagram illustrates the process of the protrusion 361 moving from the resting position to bring the pull-out end 52 to the next predetermined pull-out length. When the protrusion 361 is in the resting position, if the user needs to continue pulling out the pull-out end 52, the user can pull the pull-out end 52 to move, causing the rotating wheel 32 to move around the first direction M, causing the protrusion 361 to move around the first direction M in the outer channel 372. Then, under the action of the abutment part 3721 and the stop part 3741, the protrusion 361 moves to the inner channel 371 until the pull-out length of the pull-out end 52 reaches the next predetermined pull-out length. Under the action of the coil spring 34, the protrusion 361 moves to the resting position.

[0096] Figure 14 The diagram illustrates the operation of the protrusion 361 within the guide groove 37 after the extraction end 52 is released before reaching the predetermined extraction length. After the extraction end 52 is released before reaching the predetermined extraction length, the rotating wheel 32 rotates around the second direction N under the action of the coil spring 34, causing the protrusion 361 to return to its first initial position along the inner channel 371.

[0097] In this embodiment, the winding assembly 30 can wind the air tube 50 around the rotating wheel 32. During the process of the extraction end 52 of the air tube 50 being pulled out, the rotating wheel 32 can rotate relative to the base 31, and the protrusion 361 can move along the guide groove 37 to the resting part 3731, so that the extraction end 52 is fixed to the predetermined extraction length. This not only facilitates the use of the air tube 50, but also avoids the situation where the rotating wheel 32 rotates in the opposite direction during the use of the air tube 50, causing the air tube 50 to be wound up, thus improving the user experience.

[0098] like Figure 2 , Figure 15 and Figure 16 As shown, the inflation assembly 40 includes an inflation needle 41 and a needle holder 42 for fixing the inflation needle 41. The wine product preservation device 100 also includes a detachable structure 70 connecting the housing 60 and the inflation assembly 40. A fixing frame 61 is also provided inside the housing 60, and the detachable structure 70 is used to connect the fixing frame 61 and the needle holder 42, thereby facilitating the installation and fixing of the inflation assembly 40.

[0099] Specifically, the detachable structure 70 includes a claw 71 and a slot 72 that engages with the claw 71. The claw 71 is disposed in one of the housing 60 and the needle holder 42, and the slot 72 is disposed in the other of the housing 60 and the needle holder 42. Of course, in other embodiments of this utility model, the detachable structure 70 may also be configured in other forms, such as: the needle holder 42 is provided with an insertion hole, and the fixing bracket 61 is provided with a fixing post 742, the fixing post 742 being insertable into the insertion hole.

[0100] Optionally, at least two detachable structures 70 may be provided around the outer periphery of the needle holder 42. In this embodiment, two detachable structures 70 are provided, and the two detachable structures 70 are arranged opposite to each other. The claw 71 is provided in the housing 60, and the slot 72 is provided in the needle holder 42.

[0101] like Figures 17 to 19 As shown, the detachable structure 70 includes a housing 73 and a sliding body 74 that moves relative to the housing 73. A claw 71 is connected to the sliding body 74, and the claw 71 has a free end 711 and a fixed end 712 opposite to the free end 711. The claw 71 is connected to the sliding body 74 through the fixed end 712. The housing 73 can be fixedly mounted relative to the fixing frame 61. The housing 73 is provided with a pressing part 731.

[0102] The claw 71 has a retracted state and an open state. The sliding body 74 can move within the housing 73. When the pressing part 731 abuts against the free end 711, the claw 71 is in the retracted state and can engage with the slot 72, thereby fixing the needle seat 42 to the fixing frame 61. When the pressing part 731 disengages from the free end 711, the claw 71 is in the open state and can disengage from the slot 72, thereby facilitating the removal of the needle seat 42 from the fixing frame 61.

[0103] Furthermore, the sliding body 74 also includes a relief portion 741 that abuts against or disengages from the needle holder 42. During the process of fixing the needle holder 42 to the fixing frame 61, the needle holder 42 moves toward the fixing frame 61. The needle holder 42 can push the sliding body 74 to move through the relief portion 741, causing the claw 71 to move from the open state to the retracted state, thereby facilitating the fixing of the needle holder 42.

[0104] like Figure 17 , Figure 20 and Figure 21As shown, the detachable structure 70 further includes a connecting rod 75 connecting the sliding body 74 and the housing 73. The sliding body 74 or the housing 73 is provided with a slide rail 76 for the end of the connecting rod 75 to move. During the movement of the end of the connecting rod 75 within the slide rail 76, the pawl 71 can be locked to the retracted state or unlocked from the retracted state to the open state, thereby fixing or disengaging the needle seat 42. In this embodiment, the slide rail 76 is disposed on the sliding body 74.

[0105] Furthermore, the slide 76 has a first positioning part 761 and a second positioning part 762, with the first positioning part 761 positioned relative to the second positioning part 762 and close to the claw 71. When the end of the connecting rod 75 is located at the first positioning part 761, the claw 71 is in a retracted state; when the end of the connecting rod 75 is located at the second positioning part 762, the claw 71 is in an open state.

[0106] Specifically, the connecting rod 75 has a first end 751 and a second end 752. The first end 751 can move within the slide rail 76, and the second end 752 is rotatably connected to the housing 73. Both the first positioning part 761 and the second positioning part 762 are configured to be recessed away from the claw 71, thereby facilitating the limiting of the first end 751.

[0107] In this embodiment, the slide 76 further includes a first guide section 763 and a second guide section 764 that are connected to each other. The first positioning part 761 is located at the end of the first guide section 763, and the second positioning part 762 is located at the end of the second guide section 764. The first guide section 763 is configured to extend from the first positioning part 761 in a direction away from the second positioning part 762, and the second guide section 764 is configured to extend from the end of the first guide section 763 away from the first positioning part 761 toward the second positioning part 762.

[0108] Furthermore, two sets of the first guide segment 763 and the second guide segment 764 can be provided, with the two sets of the first guide segment 763 and the second guide segment 764 respectively located on the left and right sides of the first positioning part 761. The two sets of the first guide segment 763 and the second guide segment 764 enable the slide 76 to be arranged in a ring shape. That is, the first end 751 can move unidirectionally within the slide 76 to realize the change of the first end 751 from the first positioning part 761 to the second positioning part 762. Of course, the first end 751 can also move from the slide 76 on the left or right side of the first positioning part 761 to realize the change of the first end 751 from the first positioning part 761 to the second positioning part 762.

[0109] In this embodiment, the first end 751 moves unidirectionally within the slide rail 76, meaning that the first end 751 can only move in one direction within the slide rail 76. The slide rail 76 includes a first guide section 763 and a second guide section 764 located to the left of the first positioning part 761, and a first guide section 763 and a second guide section 764 located to the right of the first positioning part 761. A step difference is formed at the connection points of the first guide section 763 located to the left of the first positioning part 761 and the first guide section 763 located to the right of the first positioning part 761, and at the connection points of the second guide section 764 located to the left of the first positioning part 761 and the second guide section 764 located to the right of the first positioning part 761.

[0110] like Figure 21 As shown, each guide section in the slide 76 has a step difference at its connection. The slide 76 is sequentially provided with a first step 7651, a second step 7652, a third step 7653, and a fourth step 7654, and these steps are arranged in a counterclockwise direction, so that the first end 751 can only move in one direction. In this embodiment, the first end 751 moves in a counterclockwise direction.

[0111] Specifically, the height of the connection between the first step 7651 and the second guide segment 764 is higher than the height of the connection between the first step 7651 and the first guide segment 763; the height of the connection between the second step 7652 and the first guide segment 763 on the left side of the first positioning part 761 is higher than the height of the connection between the second step 7652 and the first guide segment 763 on the right side of the first positioning part 761; the height of the connection between the third step 7653 and the first guide segment 763 is higher than the height of the connection between the third step 7653 and the second guide segment 764; and the height of the connection between the fourth step 7654 and the second guide segment 764 on the right side of the first positioning part 761 is higher than the height of the connection between the fourth step 7654 and the second guide segment 764 on the left side of the first positioning part 761.

[0112] In this embodiment, the detachable structure 70 further includes a reset elastic member 77 connecting the sliding body 74 and the housing 73. During the movement of the end of the connecting rod 75 from the second positioning part 762 to the first positioning part 761, the deformation of the reset elastic member 77 increases. When the end of the connecting rod 75 disengages from the first positioning part 761, under the action of the reset elastic member 77, the end of the connecting rod 75 can move from the first positioning part 761 to the second positioning part 762.

[0113] Furthermore, one end of the reset elastic member 77 is connected to the housing 73, and the other end of the reset elastic member 77 is connected to the sliding body 74. The sliding body 74 is also provided with a fixing post 742 for mounting the reset elastic member 77.

[0114] The working process of the detachable structure 70 is as follows: During the process of fixing the needle seat 42 to the fixing frame 61, the needle seat 42 moves toward the fixing frame 61. The needle seat 42 can push the sliding body 74 to move through the abutment part 741, so that the sliding body 74 slides in the housing 73, so that the pressing part 731 abuts against the free end 711, so that the claw 71 is in a retracted state, and the end of the connecting rod 75 moves from the second positioning part 762 to the first positioning part 761, thereby keeping the claw 71 in the retracted state.

[0115] When the needle holder 42 needs to be removed from the fixing frame 61, the needle holder 42 can move back to the fixing frame 61. The needle holder 42 pushes the sliding body 74 to move through the abutment part 741, so that the sliding body 74 slides in the housing 73, causing the end of the connecting rod 75 to disengage from the first positioning part 761. Then, under the action of the reset elastic member 77, the sliding body 74 moves, and the end of the connecting rod 75 moves to the second positioning part 762, so that the claw 71 is in an open state, thereby facilitating the removal of the needle holder 42 from the fixing frame 61.

[0116] like Figure 16 As shown, the inflation needle 41 has a front end and a rear end connected to the needle holder 42. The inflation needle 41 is provided with an exhaust channel 411 and an intake channel 412 connected to the air supply assembly 10. The exhaust channel 411 has an exhaust port 4111 located at the front end of the inflation needle 41, and the intake channel 412 has an air inlet 4121 located at the front end of the inflation needle 41. The air inlet 4121 is positioned away from the needle holder 42 relative to the exhaust port 4111. That is, the air inlet 4121 is positioned close to the front end of the inflation needle 41 relative to the exhaust port 4111, thereby increasing the exhaust rate, facilitating the removal of air from the wine container, preventing oxidation of the wine inside the container, and thus ensuring the storage quality of the wine.

[0117] Furthermore, the diameter of the air intake channel 412 is less than or equal to the diameter of the exhaust channel 411, thereby enabling the gas in the wine container to be discharged quickly and improving the inflation efficiency.

[0118] Optionally, the air outlet 4112 of the exhaust channel 411 can be located at the rear end of the inflation needle 41, as long as it allows for convenient gas discharge.

[0119] like Figure 16 and Figure 22 As shown, the inflation assembly 40 further includes a limiting structure 43 disposed on the needle holder 42, and the wine container of the alcoholic beverage product is provided with a locking part that cooperates with the limiting structure 43. The needle holder 42 may be provided with a limiting cavity 422 for accommodating the limiting structure 43. The cooperation between the limiting structure 43 and the locking part can fix the needle holder 42 to the wine container, which is convenient for user use and can prevent the inflation needle 41 from detaching from the wine container during inflation.

[0120] Optionally, the bottle neck 132 or the stopper of the wine container is provided with a protrusion to form the locking part. The pin seat 42 is provided with a groove 421 that mates with the bottle neck 132, and the limiting structure 43 is disposed in the groove 421.

[0121] Furthermore, the limiting structure 43 includes a limiting elastic member 432 and a ball head 433 that is floating relative to the needle seat 42. One end of the limiting elastic member 432 is connected to the ball head 433, and the other end of the limiting elastic member 432 is fixedly disposed relative to the needle seat 42.

[0122] In this embodiment, the limiting structure 43 further includes a base 431 that defines a floating cavity 4311. The ball head 433 and the limiting elastic member 432 are disposed in the floating cavity 4311, thereby integrating the ball head 433 and the limiting elastic member 432 into the base 431, which facilitates assembly and improves assembly efficiency.

[0123] Furthermore, the floating cavity 4311 is provided with an opening 4312 for the ball head 433 to move, and the diameter of the opening 4312 is smaller than the maximum outer diameter of the ball head 433, thereby preventing the ball head 433 from detaching from the floating cavity 4311 and preventing the limiting structure 43 from working stably.

[0124] like Figure 15 , Figure 16 , Figure 23 and Figure 24 As shown, the inflation assembly 40 is relatively exposed outside the housing 60. The inflation assembly 40 includes a needle cover 44 covering the inflation needle 41. The needle cover 44 can prevent the inflation needle 41 from being exposed, thereby protecting the inflation needle 41 and preventing it from being contaminated.

[0125] Furthermore, the inflation assembly 40 also includes a positioning structure 45 disposed on the needle holder 42, and the needle cover 44 is provided with a mating part 441 that cooperates with the positioning structure 45. The mating part 441 may be configured as a positioning groove located inside the needle cover 44. In addition, the positioning structure 45 may be configured as a structure similar to the limiting structure 43 described above, and will be described in this application as the limiting structure 43.

[0126] Furthermore, at least two positioning structures 45 may be provided, and the two positioning structures 45 are evenly arranged around the outer periphery of the needle seat 42, thereby ensuring that the needle cover 44 can be installed firmly.

[0127] In this embodiment, the outer side of the needle cover 44 is also provided with a plurality of protrusions 442. The protrusions 442 can make it easier for the user to hold the needle cover 44, increase friction, and make it easier for the user to insert the needle cover 44.

[0128] Furthermore, the needle cover 44 is exposed relative to the operating area 63 to facilitate user use of the inflation assembly 40. A protrusion 443 is also provided on the outer side of the needle cover 44, and the housing 60 is provided with a mating part that engages with the protrusion 443, thereby facilitating the positioning of the needle cover and the positioning and installation of the inflation assembly 40. During the use of the wine product preservation device 100, the user can remove the needle cover 44 and the needle holder 42 together from the fixing frame 61 for convenient use.

[0129] like Figures 25 to 29 As shown, one embodiment of this utility model also provides a refrigeration device, which includes a wine preservation device 100, a cabinet defining a storage compartment, and a mounting structure 90 connecting the wine preservation device 100 and the cabinet. The wine preservation device 100 can be installed into the storage compartment through the mounting structure, which is not only convenient to install and disassemble, but also can be used independently, which helps to expand the application scenarios of the wine preservation device, meet the diverse usage needs of users, and improve the user experience.

[0130] In this embodiment, the hanging structure 90 includes a hook 91 and a hanging groove 92 that cooperates with the hook 91. The hook 91 has a locking part 911, which engages with the hanging groove 92. Of course, in some embodiments, the hanging structure 90 can also be configured in other forms, as long as it facilitates the assembly and disassembly of the wine product preservation device 100.

[0131] Optionally, at least two hanging structures 90 are provided. The inner wall of the cabinet may be provided with the hanging groove 92, or the cabinet may also be provided with a fixing plate 93 forming the hanging groove 92. The fixing plate 93 can be fixed to the inner wall of the cabinet by a threaded structure or a snap-fit ​​structure. In this embodiment, three hanging structures 90 are provided, and the three hanging structures 90 are arranged in an array on the fixing plate.

[0132] In this embodiment, the hook 91 has an installation end 912. The engaging portion 911 includes a locking section 9111 and a transition section 9112 that is away from the installation end 912 relative to the locking section 9111. The outer diameter of the transition section is larger than the outer diameter of the locking section 9111. The hanging groove 92 includes an insertion portion 921 that mates with the transition section 9112 and a locking portion 922 that mates with the locking section 9111. The insertion portion and the locking portion 922 are connected. During use of the hanging structure 90, the transition section 9112 can enter the hanging groove 92 through the insertion portion 921, thereby achieving a stable connection of the hanging structure 90 through the cooperation of the locking section 9111 and the locking portion 922.

[0133] Furthermore, the mounting structure 90 also includes a holder 931 defining the hanging groove 92 and a limiting part 932 provided on the holder 931. The limiting part 932 is used to restrict the hook 91 from moving from the holder part 922 to the insertion part 921.

[0134] Specifically, the limiting part 932 is configured as a limiting claw 933 with a suspension end 9331, the suspension end 9331 being positioned on the trajectory of the locking segment 9111 moving from the locking part 922 to the insertion part 921. When the hook 91 moves to the locking part 922, the suspension end 9331 can block the movement of the locking segment 9111, preventing the locking segment 9111 from moving from the locking part 922 to the insertion part 921, thereby achieving a stable connection between the hook 91 and the hanging slot 92.

[0135] In this embodiment, the card holder 931 includes a first sidewall 9311 and a second sidewall 9312 forming the hanging groove 92. The first sidewall 9311 and the second sidewall 9312 are located between the card slot portion 922 and the insertion portion 921. Two limiting portions 932 are provided, and the two limiting portions 932 are respectively located on the first sidewall 9311 and the second sidewall 9312.

[0136] Furthermore, the two limiting portions 932 are symmetrically arranged, and the gap formed between the two limiting portions 932 is smaller than the outer diameter of the engaging portion 911. Of course, in some embodiments, the two limiting portions 932 may also be asymmetrically arranged, as long as they can block the movement of the locking segment 9111 from the locking portion 922 to the insertion portion.

[0137] Furthermore, the locking part 922 includes a first stepped surface 9221 that cooperates with the locking section 9111 and a second stepped surface 9222 that cooperates with the abrupt change section 9112. The limiting part 932 is disposed on the first stepped surface 9221, making the connection between the hook 91 and the hanging groove 92 more stable.

[0138] In summary, the beneficial effects of this utility model are as follows: the above-mentioned wine product preservation device 100 and the refrigeration equipment thereon can fill the wine container with gas to prevent the wine product in the wine container from coming into contact with air, thereby preventing the wine product from oxidizing and affecting the taste. Furthermore, the wine product preservation device 100 is modular in design, has a compact structure, and is easy to use.
