[0044] It should be noted that the wine bottle is additionally provided with a wine head, the wine head is matched with the accommodating cavity, the wine head provides an air inlet channel and a liquid outlet channel that can enter the inside of the wine bottle, and the air inlet channel and the liquid outlet channel are respectively in abutment with the first connecting pipe 10 and the second connecting pipe 11.

[0045] Further, the body 1 is provided with a liquid outlet portion 12, the liquid outlet 13 is arranged on the liquid outlet portion 12, and the liquid outlet 13 is connected with a liquid outlet pipe 29. The liquid outlet pipe 29 can be shaped according to actual conditions, so as to meet the actual needs of different users. For example, some users want the wine outlet of the liquid outlet pipe 29 to be higher, and then the liquid outlet pipe with a higher wine outlet can be used.

[0046] Further, the liquid outlet pipe 29 and the liquid outlet 13 can be detachably connected, and the liquid outlet pipe 29 and the liquid outlet 13 can be rotatably arranged. It can be understood that when the liquid outlet pipe 29 is used, the liquid outlet pipe 29 can be detached from the liquid outlet 13 for cleaning, and the liquid outlet pipe 29 and the liquid outlet 13 can be rotatably arranged, that is, after the liquid outlet pipe 29 and the liquid outlet 13 are assembled, the liquid outlet pipe 29 can still rotate around the axis of the liquid outlet 13 and stop at any angle, so that the end of the liquid outlet pipe 29 is rotated to a specified height to adapt to wine cups of different heights, that is, when the wine cup is too short, the liquid outlet pipe 29 can be rotated to the specified height to prevent the wine from splashing when the wine is poured out.

[0047] Further, the liquid outlet of the liquid discharge conduit 29 is provided with a cap, which is a silica gel cap in an embodiment.

[0050] Further, as shown in Figure 5 The outer surface of the end of the liquid discharge conduit connected with the liquid outlet 13 is provided with a sealing layer 15. The liquid discharge conduit and the liquid outlet 13 are detachably connected. When used for a period of time, the liquid discharge conduit can be detached for flushing. The sealing layer 15 can ensure that the liquid discharge conduit and the liquid outlet 13 are tightly connected and prevent the phenomenon of liquid leakage.

[0051] Further, as shown in Figure 5 The sealing layer 15 includes a plurality of convex rings 16, which abut against the inner wall of the liquid outlet 13. The convex rings 16 can reduce the contact area between the sealing layer 15 and the liquid outlet 13, i.e., can reduce the friction between the sealing layer 15 and the liquid outlet 13. While ensuring that the liquid discharge conduit and the liquid outlet 13 are tightly connected, the convex rings 16 can enable the liquid discharge conduit and the liquid outlet 13 to be quickly installed, preventing the friction between the sealing layer 15 of the liquid discharge conduit and the liquid outlet 13 from being too large, which causes difficulty in installation of the liquid discharge conduit and the liquid outlet 13.

[0052] Further, as shown in Figure 1 The accommodating cavity 2 is provided with a positioning portion 31 for facilitating fixation of the wine bottle with the accommodating cavity 2. It should be noted that the wine bottle is matched with a wine head for installation with the accommodating cavity 2. The wine head is correspondingly provided with a clamping portion matched with the positioning portion 31. In this embodiment, the positioning portion 31 is a slot, and the width of the top end of the slot is greater than the width of the bottom end of the slot, which facilitates quick clamping of the clamping portion on the wine head with the positioning portion 31 and effectively provides the effect of assembly.

[0053] It should be noted that the bottom end of the slot is arranged in an arc shape, and correspondingly, the bottom end of the clamping part is also arranged in an arc shape, facilitating the clamping part to quickly enter the slot.

[0054] Further, the body 1 is also provided with a deoxidizing device 4, and the air vent 5 is communicated with the air outlet 20 of the deoxidizing device 4 through an air pipe. It can be understood that the deoxidizing device 4 is used to remove oxygen in the air, so that the gas entering the air vent 5 does not contain oxygen, preventing the wine in the wine bottle from being oxidized and deteriorated.

[0055] Further, as shown in Figure 7 and Figure 8 The deoxidizing device 4 includes a shell 17, the shell 17 is provided with a connecting structure for detachable connection with the deoxidizing device, the shell 17 is inlaid on the outer side of the deoxidizing device through the connecting structure, which can avoid the main parts inside the deoxidizing device as much as possible, so that more space is provided for installing the shell 17, that is, the volume of the shell 17 can be made larger, the shell 17 is provided with a chamber 18 for filling deoxidizing agent, the shell 17 is provided with an air inlet groove 19, an air inlet 20 and an air outlet, the air inlet groove 19 is communicated with the air inlet 20, the chamber 18 is provided with an air outlet cavity 21 at the position of the air outlet, and the inner wall of the air outlet cavity 21 is provided with a through hole communicated with the chamber 18.

[0056] It should be noted that the shell 17 is inlaid on the outer side of the deoxidizing device through the connecting structure, so that the shell 17 can be directly taken out from the outside of the deoxidizing device without disassembling the inside of the deoxidizing device, and the disassembling process is simple, which only needs to contact the connection between the shell 17 and the deoxidizing device; after the shell 17 and the deoxidizing device are assembled, there is a gap between the shell 17 and the deoxidizing device which is communicated with the outside air, the air inlet groove 19 can be communicated with the outside air through the gap, or the shell 17 of the deoxidizing device is provided with a hole which communicates the air inlet groove 19 with the outside air.

[0057] By inlaying the deoxidizing device 4 on the outer side of the deoxidizing device, and detachably connecting the deoxidizing device 4 with the deoxidizing device, the deoxidizing device 4 can be easily disassembled and replaced, and the deoxidizing device 4 is inlaid on the outer side of the deoxidizing device, which can avoid the main parts of the deoxidizing device, so that the volume of the chamber 18 can be larger, and the air inlet groove 19 is ventilated with the outside air, which effectively prolongs the service life of the deoxidizing agent.

[0058] Furthermore, the air inlet slot 19 includes a first groove 22 disposed on the top surface of the housing 17 and a second groove 23 disposed on the side surface of the housing 17. The first groove 22 communicates with the second groove 23. A side air inlet is disposed on the body 1, and the side air inlet communicates with the second groove 23. It is understood that the gap may exist between the top surface of the housing 17 and the deoxygenation device, or it may exist between the side surface of the housing 17 and the deoxygenation device. That is, the first groove 22, the second groove 23, and the side air inlet can ensure that the air inlet 20 is connected to the outside air. The side air inlet is disposed on the side of the body 1, that is, in a less conspicuous part of the body 1, which has a hiding effect and effectively improves the overall aesthetics of the device.

[0059] Furthermore, the housing 17 includes an upper shell and a bottom shell. The bottom of the upper shell is provided with a first convex edge 24 in the shape of a ring at the position corresponding to the air outlet. The surface of the bottom shell is provided with a third groove 25 that is adapted to the convex edge. The first convex edge 24 abuts against the third groove 25, so that the air outlet cavity 21 is formed between the first convex edge 24 and the third groove 25.

[0060] It is understandable that, since the chamber 18 is filled with the deoxidizer, the outlet chamber 21 can prevent the deoxidizer from directly entering the outlet, that is, prevent the deoxidizer from blocking the outlet.

[0061] Furthermore, such as Figure 4 As shown, a partition 26 is provided inside the machine body 1, dividing the interior of the machine body 1 into an inner cavity 27 and an outer cavity 28. The electrical control components and the water pump 3 are installed in the inner cavity 27, and the deoxygenation device 4 is embedded in the outer cavity 28. A sealing strip is provided between the partition 26 and the inner wall of the machine body 1, and the partition 26 is sealed to the inner wall of the machine body 1 through the sealing strip to prevent external moisture or water from entering the inner cavity 27 and thus damaging the electrical control components.

[0062] In summary, the wine drinking machine, the one-way valve can prevent the wine in the wine bottle from flowing out through the air pipe, the cross valve can prevent the red wine in the wine bottle from slowly dripping out to the liquid discharge port due to pressure, and can also prevent external air from entering the bottle through the liquid discharge port, the sealing layer can ensure that the liquid discharge conduit and the liquid discharge port are connected tightly, prevent the phenomenon of liquid leakage, the partition plate is sealed and connected with the inner wall of the machine body through the sealing strip, prevents external moisture or water from entering the inner cavity, thereby damaging the electric control assembly.
