Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a wine dispensing machine and a wine dispensing needle. Background Art

[0002] Wine is a common and important beverage in our daily lives. It contains ethanol, a fermented form of sugar, as well as a large amount of tannins and polyphenols. These substances are highly susceptible to oxidation when exposed to oxygen. Therefore, once the lid of a bottle of red wine is opened, its seal is compromised. Consequently, if the entire bottle is not consumed within a short period of time, the polyphenols in the wine will react chemically with oxygen in the air, causing the wine to deteriorate or even spoil.

[0003] To solve this problem, people mainly fix the red wine bottle on a wine dispenser. The wine dispenser is equipped with a needle that can be inserted into the wine bottle. The needle passes through the cork at the bottle mouth and contacts the wine. The wine is taken out through the needle to minimize the damage to the sealing of the bottle mouth.

[0004] However, when the same bottle of wine is consumed again, if the wine dispenser is replaced with another bottle, the wine needle needs to be inserted through the cork in the bottle again. Therefore, after multiple consumption, the airtightness of the cork will decrease, resulting in deterioration of the wine quality. Utility Model Content

[0048] Furthermore, the technical features involved in the different embodiments of the present invention described below may be combined as long as they do not conflict with each other. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art without requiring creative effort are also within the scope of protection of the present invention.

[0049] like Figure 1-Figure 2 As shown, the wine dispensing machine provided by the embodiment of the present invention includes a frame 1, a wine bottle fixing device 2 arranged on the frame 1, a drainage device 3 and a liquid outlet device 4. Among them, the wine bottle fixing device 2 is used to fix the wine bottle 5, and the wine bottle fixing device 2 includes a locking mechanism for limiting the movement of the wine bottle. The drainage device 3 is arranged opposite to the wine bottle fixing device 2, and the drainage device 3 is used to communicate with the wine bottle 5 through the wine collection needle 6. The drainage device 3 includes a connector 30 for connecting to the wine collection needle 6, and a walking mechanism 31 for driving the connector 30 to approach or move away from the wine bottle fixing device 2. Among them, as Figure 3 As shown, the wine extraction needle 6 includes a needle body 61 and a tail seat 62. One end of the connector 30 is connected to the tail seat 62, and the other end is connected to the liquid outlet device 4. The wine in the wine bottle 5 flows into the liquid outlet device 4 through the wine extraction needle and the drainage device, and then enters the cup from the liquid outlet device 4 for people to drink.

[0050] like Figure 1 、 Figure 2 and Figure 4 As shown, the wine dispenser also includes a needle box 7 for storing the wine needle 6, as shown in FIG. Figure 5 and Figure 6 As shown, the needle box 7 is equipped with a feed bin 70 for storing the wine needle 6. At one end of the needle box 7 is a pre-launch bin 71 for accommodating a single wine needle 6. The pre-launch bin 71 is connected to the feed bin 70, allowing the wine needle 6 to enter the pre-launch bin 71 from the feed bin 70. The wine needle 6 in the pre-launch bin 71 is driven by the connector 30 toward the wine bottle fixture 2 until the wine needle 6 penetrates the bottle mouth 50 of the wine bottle 5. The feed bin 70 can accommodate multiple wine needles 6.

[0051] When the wine dispenser is in use, the travel mechanism 31 drives the connector 30 to contact the wine needle 6, and drives the wine needle 6 close to the wine bottle 5, thereby achieving the action of the wine needle 6 piercing the wine bottle 5. When the wine bottle 5 is pulled out, the wine needle 6 remains in the bottle mouth 50 and is separated from the connector 30. When a new wine bottle 5 is inserted again, the sensor provided in the wine dispenser recognizes that the wine bottle 5 does not carry the wine needle 6, and controls the travel mechanism 31 to drive the connector 30 to reset, and drive the connector 30 to contact the wine needle 6 again. The new wine needle 6 in the waiting chamber 71 is inserted into the wine bottle 5 again, and the docking of the wine bottle 5 and the drainage device 3 is automatically completed.

[0052] The wine-dispensing machine disclosed in this embodiment can use the standby wine-dispensing needle 6 stored in the needle box 7 to replace the wine-dispensing needle 6 after the wine-dispensing needle 6 is pulled out together with the wine bottle. When the wine bottle is replaced, wine can be quickly dispensed without the need to separately install the wine-dispensing needle. It is only necessary to replace the needle box 7 or fill the needle box 7 with the wine-dispensing needle 6.

[0053] In order to avoid the wine needle 6 from being unstable when moving in the feeding bin 70, Figure 4-Figure 6 As shown, the feed bin 70 is further provided with a guide rail 72 adapted for the tailstock 60, and the guide rail 72 is provided with a retaining groove 720 adapted for the tailstock 62. The tailstock 62 of the wine extraction needle 6 is provided with a retaining protrusion 63, which is adapted to the retaining groove 720 of the guide rail 72. The retaining protrusion 63 is located at the end of the tailstock 62 adjacent to the needle body 61. Thus, the engagement between the retaining protrusion 63 and the retaining groove 720 allows the tailstock 62 to move along the extension direction of the guide rail 72. The retaining groove 720, through the retaining protrusion 63, limits the freedom of the tailstock 62 in a direction perpendicular to the extension direction of the guide rail 72, guiding the feeding of the wine extraction needle 6, preventing jumping and congestion during the movement of the wine extraction needle 6, and improving the stability of the equipment.

[0054] In this embodiment, Figure 4 As shown, since the wine-taking needle 6 is received in the feeding bin 70 with the needle body 61 perpendicular to the guide rail 72 , a through slot 721 is provided on the top of the guide rail 72 for the needle body 61 to move.

[0055] like Figure 7 and Figure 8 As shown, one end of the connector 30 is provided with a socket 301 for fixing the tailstock 62, the bottom of the socket 301 is provided with a plug connector 302 for inserting the tailstock 62, and the other end of the connector 30 is provided with a drainage tube connected to the plug connector 302. Figure 7 As shown, the socket 301 has a cavity for nesting the tailstock 62, with the socket 301 located at the bottom of the cavity. When the socket 301 and tailstock 62 are docked, the tailstock 62 is embedded in the cavity, and the plug connector 302 is inserted into the tailstock 62 to connect with the needle body 61. This ensures that the connector 30 is securely connected to the wine needle 6 through the socket 301, and the connection between the two is also established.

[0056] like Figure 9 As shown, a flow channel 303 is provided on the side wall of the top of the plug connector 302. When the top of the plug connector 302 encounters an obstacle, the top of the plug connector 302 can be used to push the obstacle away, and the liquid in the tailstock 62 flows into the plug connector 302 through the flow channel 303, avoiding clogging of the plug connector 302.

[0057] In this embodiment, Figure 7 As shown, the walking mechanism 31 includes a cantilever 313 connected to the joint 30, and the walking mechanism 31 is connected to the joint 30 through the cantilever 313. Figure 4-Figure 6As shown, in order to prevent the connector 30 from interfering with the side wall of the ready-to-fire chamber 71 when passing through the ready-to-fire chamber 71, a notch 710 is provided on the side wall of the ready-to-fire chamber 71 for the cantilever 313 to pass through.

[0058] like Figure 4 As shown, in order to prevent the needle body 61 from being contaminated by dust, the needle box 7 also includes a dust cover 73 arranged above the feed bin 70. The dust cover 73 is adjacent to the side of the waiting bin 71 and is provided with a first opening 730 for the wine needle 6 to pass through, so that the wine needle 6 can freely enter and exit the waiting bin 71.

[0059] When the wine extraction needle 6 in the waiting bin 71 is used, in order to allow the wine extraction needle 6 in the feeding bin 70 to be replaced in the waiting bin 71, the needle box 7 is also provided with a feeding mechanism for pushing the wine extraction needle 6 from the feeding bin 70 to the waiting bin 71.

[0060] like Figure 2 As shown, the feeding mechanism includes a first spring 74 arranged at one end of the needle box 7 away from the waiting chamber 71. The first spring 74 provides the power required for the wine-taking needle 6 in the feeding chamber 70 to enter the waiting chamber 71, so that the wine-taking needle 6 can automatically fill the position.

[0061] In order to avoid the collision of the wine taking needle 6 in the waiting chamber 71 when the connector 30 is reset, Figure 7 and Figure 8 As shown, the feeding mechanism also includes a locking component for releasing or blocking the wine-taking needle 6 from entering the waiting chamber 71 , and the locking component is arranged at one end of the feeding chamber 70 adjacent to the waiting chamber 71 .

[0062] When the connector 30 is located between the wine bottle fixing device 2 and the waiting chamber 71, the locking assembly blocks the wine needle 6 from entering the waiting chamber 71; when the waiting chamber 71 is located between the connector 30 and the wine bottle fixing device 2, the locking assembly allows the wine needle 6 to enter the waiting chamber 71.

[0063] like Figure 7 and Figure 8 As shown, the locking assembly includes a movable part 33 that can move relative to the feeding bin 71. The moving trajectory of the movable part 33 has a limiting position where it contacts the wine taking needle 6 in the feeding bin 71 to restrict it from entering the waiting bin 71, and a releasing position where it separates from the wine taking needle 6 in the feeding bin 70 to release it from entering the waiting bin 71.

[0064] like Figure 8 As shown, the movable part 33 is provided with a pressing piece 331 extending to the moving track of the joint 30. On the moving track of the joint 30, when the joint 30 moves in a direction away from the wine bottle fixing device 2 and passes through the ready-to-fire chamber 71, the joint 30 can be transmission-connected with the pressing piece 331 to drive the movable part 33 to move to the release position.

[0065] In this embodiment, the wine bottle fixing device 2 is located above the needle box 7, and the movement trajectory of the connector 30 is in the vertical direction. When the connector 30 moves to below the firing chamber 71, the connector 30 is in the reset state. At this time, the connector 30 drives the movable member 33 to the release position via the pressing piece 331. The movable member 33 disengages from the tailstock 2 of the wine needle 6 to be replaced, and the wine needle 6 enters the firing chamber 71.

[0066] When the connector 30 is in the reset state, the distance between the connector 30 and the wine needle 6 in the pre-launch chamber 71 is greater than the distance between the movable member 33 and the wine needle to be replaced. Thus, when the connector 30 moves from the reset state toward the bottle fixture 2, the movable member 33 simultaneously moves upward and contacts the tailstock 2 of the wine needle 6 to be replaced, preventing the wine needle 6 to be replaced from entering the pre-launch chamber 71.

[0067] As the connector 30 continues to move upward, the connector 30 begins to contact the wine extraction needle 6 in the ready-to-fire chamber 71, and drives the wine extraction needle 6 to move toward the wine bottle fixing device 2 until the connector 30 is disengaged from the pressing piece 331, the pressing piece 331 moves upward to the limit position, and the movable part 33 also stops moving accordingly.

[0068] Therefore, before the connector 30 contacts the wine-taking needle 6 in the waiting chamber 71, the movable part 33 can prevent the wine-taking needle to be filled from continuing to move toward the waiting chamber, thereby restricting the wine-taking needle 6 to be filled from entering the waiting chamber 71, and avoiding the connector 30 from colliding with the wine-taking needle 6 in the waiting chamber 71 when it returns to its original position.

[0069] When the pressing piece 331 is separated from the connector 30 , in order to realize the automatic reset of the movable member 33 to the limit position, the locking assembly in this embodiment further includes a reset member for actively moving the movable member 33 to the limit position.

[0070] Specifically, if Figure 10-12 As shown, the locking assembly includes a support body 34 for securing the movable member 33. The movable member 33 is movably connected to the support body 34. The support body 34 is equipped with a limiting structure for limiting the range of movement of the pressing plate 331. In this embodiment, the support body 31 is a hollow structure. The movable member 33 is sleeved within the support body 34. The limiting structure includes a limiting groove 340 defined in the side wall of the support body 34. The pressing plate 331 extends outside the support body 34 through the limiting groove 340. The reset member is a second spring 35 disposed between the movable member 33 and the support body 34.

[0071] In this way, the support body 34 supports and restrains the movable part 33, and limits the moving stroke of the movable part 33 to the two ends of the limit groove 340, so as to complete the switching of the movable part 33 between the release position and the limit position. By accurately controlling the moving state of the wine-taking needle 6 to be filled in the storage bin 70, it can not only realize automatic filling in the waiting bin 71, but also avoid the collision of the joint 30 with the wine-taking needle 6 to be filled when it is reset.

[0072] In this embodiment, Figure 13 As shown, the drainage device 3 also includes a mounting plate 36 fixed to the frame 1, to which the latch assembly and the needle cartridge 7 are attached. A second opening 75 is defined at the bottom of the storage bin 70 for access by the movable member 33. A needle cartridge mounting seat 360 is also provided on the mounting plate 36, with a slide groove 361 formed on the surface of the needle cartridge mounting seat 360. A retaining edge 76 is provided at the bottom of the needle cartridge 7, which mates with the slide groove 361. This allows for quick installation of the needle cartridge 7 through the combination of the retaining edge 76 and the retaining edge 76.

[0073] like Figure 13 As shown, the travel mechanism 31 includes a lead screw 310 fixedly connected to the frame 1, a nut 311 adapted to fit the lead screw 310, and a lifting platform 312 fixedly connected to the nut 311. The joint 30 is fixedly connected to the lifting platform 312 via a cantilever. The travel mechanism 31 also includes a servo motor 3 for controlling the rotation of the lead screw 310. By controlling the forward and reverse rotation of the servo motor, the start and stop of the lead screw 310 and the rotation direction are controlled, thereby controlling the raising and lowering of the lifting platform 312.

[0074] Frame 1 is also equipped with limit switches, located at the two extreme positions of the lift platform 312's ascent and descent. The limit switches are electrically connected to the servo motor's control circuit. When the lift platform 312 contacts the limit switches, the servo motor stops operating until the system actively controls the servo motor. In this way, the limit switches control the lift platform 312's ascent and descent, thereby controlling the advance of the wine needle 6 and precisely controlling the insertion depth of the needle 61 into the wine bottle 5.

[0075] In addition, in other embodiments of the present invention, the wine bottle 5 can also be fixed in the horizontal direction, and the wine bottle fixing device 2 and the drainage device 3 are distributed in the horizontal direction accordingly. At the same time, the feeding direction of the walking mechanism 31 can be adjusted to be in the horizontal direction.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Under the idea of ​​the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations in different aspects of the present invention as described above. For the sake of simplicity, they are not provided in detail. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacements for some of the technical features therein.
