DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0035] like Figures 1 to 3 As shown, an embodiment of the present invention provides a wine gasification and preservation device 100, which includes a gas cylinder 10 for storing inert gas, a gasification plug 20 for being inserted into a wine bottle, a vent valve 30 for connecting or disconnecting the gas path between the gas cylinder 10 and the gasification plug 20, and a control system in communication with the vent valve 30. The gasification and preservation device 100 can deliver the inert gas in the gas cylinder 10 to the wine bottle so that the air in the wine bottle is discharged, thereby preventing the wine in the wine bottle from being oxidized and affecting the taste, and can ensure the storage quality of the opened wine, which helps to extend the storage time of the opened wine.

[0036] Furthermore, the gas-filled fresh-keeping device 100 further includes a gas detection module 51, which is used to detect the concentration of inert gas in the gas discharged from the wine bottle to the outside, and the gas detection module 51 is in communication connection with the control system. During the process of the gas-filled fresh-keeping device 100 inflating the wine bottle, the gas detection module 51 can constantly monitor the concentration n of inert gas in the gas discharged from the wine bottle to the outside, and transmit the concentration n to the control system in the form of a signal. When the concentration n reaches the preset concentration value n1, the gas-filled fresh-keeping device 100 is inflated and the inflation is terminated.

[0037] Specifically, the gas charging plug 20 has an exhaust passage 22 and an air inlet passage 21 connected to the gas bottle 10. The exhaust passage 22 has an inlet located inside the wine bottle and an outlet located outside the wine bottle. The gas detection module 51 can be arranged at the outlet of the exhaust passage 22. The gas inside the wine bottle is discharged to the outside only through the exhaust passage 22. During the period when the gas charging and fresh-keeping device 100 is charging the wine bottle, the control system can monitor the concentration n of the inert gas in the gas inside the exhaust passage 22 at all times.

[0038] Optionally, the concentration preset value n1 can be set to 2%. When the gas discharged from the wine bottle contains 2% of inert gas, and since inert gas is generally heavier than air, the inert gas can be located between the air and the wine, thereby separating the wine from the air to prevent oxidation of the wine.

[0039] In this embodiment, the gas-filling and fresh-keeping device 100 further includes a mounting frame 41, and the gas cylinder 10 is detachably mounted on the mounting frame 41. Specifically, the mounting frame 41 is provided with an insertion needle, and the insertion needle can be inserted into the gas cylinder 10 to release the inert gas in the gas cylinder 10, and the inert gas is transported into the wine bottle through the gas-filling plug 20.

[0040] Among them, at least two gas cylinders 10 can be provided. When the gas cylinder 10 needs to be replaced, the prepared gas cylinder 10 can be directly replaced, thereby improving work efficiency and making it more convenient to use. Of course, in some embodiments, the gas-filled fresh-keeping device 100 can also be supplied with gas through equipment such as an air pump.

[0041] Optionally, the inert gas may be argon.

[0042] In this embodiment, the control system further includes an air pressure detection module 52 for monitoring the air pressure in the gas cylinder 10, and the air pressure detection module 52 is in communication connection with the control system. The control system can monitor the air pressure of the gas cylinder 10 through the air pressure detection module 52; when the actual air pressure p1 in the gas cylinder 10 is less than or equal to the preset air pressure p0, the control system can remind the operator to replace the gas cylinder with an air pressure greater than p0 or add inert gas to the gas cylinder 10 until the air pressure is greater than p0, and then control the gas cylinder 10 to inflate the wine bottle; when the actual air pressure p1 in the gas cylinder 10 is greater than the preset air pressure p0, the control system can directly control the gas cylinder 10 to inflate the wine bottle, so as to realize the aeration and freshness preservation of the wine in the wine bottle.

[0043] In this embodiment, the inflatable fresh-keeping device 100 further includes an air tube 60 and a winding assembly 70 for accommodating the air tube 60. The air tube 60 is used to connect the gas cylinder 10 and the inflatable plug 20. During the use of the inflatable fresh-keeping device 100, the operator can remove the inflatable plug 20 from the device and then install it on the wine bottle to achieve inflation. In addition, the air tube 60 can be wound around the winding assembly 70 to avoid the air tube 60 being placed in a messy manner and affecting the use, which helps to improve the user's comfort.

[0044] In this embodiment, the control system can control the ventilation valve 30 to open so that the gas cylinder 10 can inflate the wine bottle. The control system can also detect whether the ventilation valve 30 is powered on for the first time. If the ventilation valve 30 is powered on for the first time, the current air pressure p2 in the gas cylinder is obtained; if the air pressure p2 is greater than the preset air pressure value p0, the gas cylinder is controlled to supply gas to the outside through the charging plug until the accumulated gas supply time t2 is greater than the preset time t3, then the gas supply is stopped, so that the air in the trachea can be discharged to fill the trachea with inert gas, thereby improving the charging efficiency.

[0045] If the air pressure p2 is not greater than the preset air pressure value p0, then replace the gas cylinder with an air pressure greater than p0 or add inert gas to the gas cylinder 10 until the air pressure p2 is greater than p0, and control the gas cylinder 10 to supply gas to the outside through the charging plug 20 until the cumulative gas supply time t2 is greater than the preset time t3, then stop supplying gas. Of course, if the ventilation valve 30 is not powered on for the first time, the air pressure p1 in the gas cylinder 10 can be detected again. If the air pressure p1>p0, the control system can control the gas cylinder 10 to inflate the wine bottle.

[0046] Optionally, the preset air pressure p1 can be set to 0.05 MPa. The preset time duration t3 can be set to 10 seconds.

[0047] In this embodiment, the vent valve 30 further includes a pressure reducing valve 31 and a switch valve 32, wherein the pressure reducing valve 31 is disposed at the exhaust port of the gas cylinder 10, and the switch valve 32 is disposed at the gas charging plug 20. During the use of the gas charging fresh-keeping device 100, the control system may first control the pressure reducing valve 31 to open, so that the inert gas in the gas cylinder 10 flows to the gas charging plug 20, so that the gas pipe 60 between the gas cylinder 10 and the gas charging plug 20 is filled with the inert gas, and then control the switch valve 32 to open;

[0048] At the end of inflation, the control system first controls the pressure reducing valve 31 to close, and then controls the switch valve 32 to close after the pressure reducing valve 31 is closed, so as to avoid closing the switch valve 32 first and causing excessive pressure in the air pipe 60. And when the pressure in the air pipe 60 is relatively small, a weaker air pipe 60 can also be used to reduce costs. In some embodiments, the pressure reducing valve 31 and the switch valve 32 can also be opened or closed at the same time.

[0049] Figure 4 1 is a schematic diagram of the structure of the aeration preservation device 100 provided in one embodiment of the present invention. The control system includes a storage unit 82 and a processing unit 81. The storage unit 82 stores a computer program that can be run on the processing unit 81. The processing unit 81 can implement the steps of the aeration preservation method for wine described below when executing the computer program in the storage unit 82. Of course, in some embodiments, the air pressure detection module and the distance detection module can also be part of the control system.

[0050] Specifically, the processing unit 81 can realize various functions of the wine aeration preservation device 100 by running or executing the computer program stored in the storage unit 82 and calling the data stored in the storage unit 82. The storage unit 82 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application program required for at least one function, etc.

[0051] In addition, the storage unit 82 may include a high-speed random access storage unit and may also include a non-volatile storage unit, such as a hard disk, a memory, a plug-in hard disk, a smart memory card (Smart Media Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), at least one disk storage unit component, a flash memory device, or other volatile solid-state storage unit components.

[0052] Exemplarily, the computer program may be divided into one or more modules / units, which are stored in the storage unit 82 and executed by the processing unit 81 to implement the present invention. The one or more modules / units may be a series of computer program instruction segments capable of implementing specific functions, which are used to describe the execution process of the computer program in the aerated fresh-keeping device 100.

[0053] The processing unit 81 may be a central processing unit (CPU), or other general processing units, a digital signal processing unit (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general processing unit may be a microprocessing unit or any conventional processing unit. The processing unit is the control center of the aerated fresh-keeping device 100, and uses various interfaces and lines to connect various parts of the entire aerated fresh-keeping device 100.

[0054] In one embodiment of the present invention, a method for aerating and preserving wine is also provided, which can be applied to the above-mentioned aerating and preserving device 100 for wine. Figure 5 As shown, the aeration preservation method comprises the following steps:

[0055] Obtaining the current gas pressure p1 in the gas cylinder; the gas cylinder stores inert gas;

[0056] Determine whether the air pressure p1 is greater than a preset air pressure p0;

[0057] If yes, control the gas cylinder to inflate the wine bottle; if no, replace the gas cylinder with one with a pressure greater than p0 or add inert gas to the gas cylinder until the pressure is greater than p0, and then control the gas cylinder to inflate the wine bottle;

[0058] During the period when the gas cylinder is inflating the wine bottle, the concentration n of the inert gas in the gas discharged from the wine bottle to the outside is monitored;

[0059] When the concentration n is greater than or equal to the preset concentration value n1, the inflation is terminated.

[0060] Optionally, the preset air pressure may be set to 0.05 MPa, and the preset concentration value n1 may be set to 2%.

[0061] Furthermore, the gas in the wine bottle is discharged to the outside only through the exhaust channel; the step of "monitoring the concentration n of inert gas in the gas discharged from the wine bottle to the outside during the period when the gas cylinder is inflating the wine bottle" is set as: monitoring the concentration n of inert gas in the gas in the exhaust channel during the period when the gas cylinder is inflating the wine bottle.

[0062] Specifically, when the control system controls the gas cylinder 10 to inflate the wine bottle, the control system can constantly monitor the actual air pressure p1 in the gas cylinder 10 through the air pressure detection module 52. When it is less than or equal to the preset air pressure p0 (0.05 MPa), it is considered that the remaining inert gas in the gas cylinder 10 is insufficient, and it is necessary to replace the gas cylinder with an air pressure greater than p0 or to add inert gas to the gas cylinder until the air pressure p1 is greater than p0, and then control the gas cylinder 10 to inflate the wine bottle; if the actual air pressure p1 in the gas cylinder 10 is greater than the preset air pressure p0 (0.05 MPa), it is considered that the remaining inert gas in the gas cylinder 10 is sufficient and the wine bottle can be inflated.

[0063] Moreover, during use, the gas detection module 51 can constantly monitor the concentration n of the inert gas in the exhaust channel 22 of the inflation plug 20, and transmit the concentration n to the control system in the form of a signal. When the concentration n is greater than or equal to the preset concentration value n1, the inflation of the inflation preservation device 100 is completed and the inflation is ended.

[0064] In this embodiment, in the step of “controlling the gas cylinder to inflate the wine bottle”, the ventilation valve is controlled to open so that the gas cylinder can inflate the wine bottle. The inflating and fresh-keeping method further includes:

[0065] Determining whether the ventilation valve is powered on for the first time;

[0066] If the ventilation valve is powered on for the first time, obtain the current gas pressure p2 in the gas cylinder;

[0067] If the air pressure p2 is greater than the preset air pressure value p0, the gas cylinder is controlled to supply gas to the outside through the charging plug until the cumulative gas supply time t2 is greater than the preset time t3; if the air pressure p2 is not greater than the preset air pressure value p0, the gas cylinder with an air pressure greater than p0 is replaced or inert gas is added to the gas cylinder until the air pressure is greater than p0, and the gas cylinder is controlled to supply gas to the outside through the charging plug until the cumulative gas supply time t2 is greater than the preset time t3;

[0068] If the ventilation valve is not powered on for the first time, the process proceeds to step “obtaining the current gas pressure p1 in the gas cylinder”.

[0069] Optionally, the preset time length t3 can be set to 10 seconds.

[0070] Specifically, when the control system detects that the ventilation valve is powered on for the first time, the control system detects the air pressure in the gas cylinder 10 through the air pressure detection module 52. When the air pressure p2 in the current gas cylinder 10 is greater than the preset air pressure p1, the control system controls the gas cylinder 10 to supply gas to the outside through the charging plug 20, and accumulates the gas supply time t2 until the gas supply time t2 is greater than the preset time t3, then stops the gas cylinder 10 from supplying gas to the outside, thereby being able to discharge the air in the air pipe 60 between the gas cylinder 10 and the charging plug 20, so that the air pipe 60 is filled with inert gas, thereby avoiding affecting the inflation effect during use.

[0071] When the air pressure p2 in the current gas cylinder 10 is less than or equal to the preset air pressure p1, the operator can replace the gas cylinder with an air pressure greater than p0 or add inert gas to the gas cylinder until the air pressure is greater than p0, and then control the gas cylinder to supply gas to the outside through the charging plug.

[0072] It should be noted that the various parameter values ​​in the above-mentioned wine aeration preservation method are experimental values ​​obtained by the inventor after several experiments, and can be set to other values ​​according to different experimental variables. Therefore, all technical solutions that are the same or similar to the present embodiment are covered within the protection scope of the present invention.

[0073] In addition, in one embodiment of the present invention, a computer-readable storage medium is also used, on which a computer program is stored. When the computer program is executed by the processing unit 81, the steps in the above-mentioned wine aeration preservation method can be implemented.

[0074] In summary, the beneficial effect of the wine aeration preservation method provided in one embodiment of the present invention is that the wine aeration preservation method can monitor the concentration n of the inert gas in the gas discharged from the wine bottle to the outside, and terminate the inflation when the concentration n is greater than or equal to the preset concentration value n1, thereby allowing the air in the wine bottle to be discharged, avoiding oxidation of the wine, ensuring the storage quality of the opened wine, and helping to extend the storage period of the opened wine.
