Description

Technical Field

[0001] This utility model relates to the technical field of beverage drinking equipment, specifically to a packaging bag, a liquid injection structure, and a wine injection device. Background Technology

[0002] Traditional beer dispensers typically use a tap-type dispensing valve for filling, but this method has many shortcomings in actual use.

[0003] First, during the bottling process, users need to hold the glass for extended periods. As beer is continuously poured in, the overall weight of the glass gradually increases, putting extra strain on the user's arms. Simultaneously, users must manually control the dispensing valve to adjust the flow rate. The entire operation requires the coordination of both hands, making it cumbersome, labor-intensive, and resulting in a poor user experience.

[0004] Moreover, the filling efficiency is low, and overflow and spillage are prone to occur during the dispensing process, which not only wastes the wine but also affects the cleanliness of the operating environment.

[0005] In addition, after beer is drawn from inside the beer dispenser, there is a certain length of conveying pipeline between the inside of the dispenser and the dispensing valve. This part of the pipeline is usually exposed outside the equipment. When refilling, in order to ensure the taste and quality of the newly dispensed beer, users often need to drain the remaining beer in the pipeline before they can receive fresh beer, resulting in high beer loss and increased operating costs.

[0006] Consumers also have a need to pack beer for takeout. However, existing beer glasses are heavy and lack a sealing structure, making them prone to leakage and spillage, which is inconvenient to carry. This is especially true for consumers who need to take beer out, as using existing beer glasses for transportation poses significant safety hazards and is inconvenient to operate.

[0007] Therefore, existing technologies need further development. Utility Model Content

[0008] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a packaging bag, liquid injection structure and beer injection equipment to solve the technical problem that users need to operate with both hands during the beer dispensing process in related technologies, which is extremely inconvenient.

[0009] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: providing a packaging bag, comprising: Bag body; The liquid outlet is connected to the inside of the bag and is used to discharge the liquid inside the bag. The inlet is connected to the inside of the bag body. The inlet and outlet are set independently. The inlet is located on the bottom or side of the bag body. A sealing component is provided at the inlet. The sealing component includes a sealing seat. The sealing seat has an inlet channel. A one-way valve is installed in the inlet channel to allow liquid to flow from the outside to the inside of the bag body in one direction.

[0010] Furthermore, the sealing seat includes a limiting component, which is disposed at one end of the sealing seat outside the bag body, and the limiting component includes a positioning groove formed on the periphery of the liquid inlet channel.

[0011] Furthermore, the packaging bag includes: The connector is located at the liquid outlet and has an internal liquid outlet channel that communicates with the liquid outlet. The cap is detachably connected to the connector to seal the liquid outlet channel.

[0012] Furthermore, the sealing assembly includes a valve cover, which is mounted on the sealing seat. The valve cover is hollow inside and has a flow port that communicates with the liquid inlet channel and the inside of the bag body.

[0013] A liquid injection structure, comprising: The aforementioned packaging bags; The injection tube carries liquid and is connected to a check valve to connect the injection tube to the inlet channel.

[0014] Furthermore, the liquid injection structure includes a support plate, the extension direction of which is perpendicular to the extension direction of the liquid injection tube. A liquid injection groove is formed through the support plate, and the liquid injection tube passes through the inside of the liquid injection groove. A positioning part is formed on the support plate around the liquid injection groove, and the positioning part and the sealing seat are grounded to limit the relative position of the packaging bag and the liquid injection tube. Furthermore, the injection structure includes a driving component, which includes a telescopic arm that is retractable along the extension direction of the injection tube. The telescopic arm is driven to connect with the injection tube and is used to drive the injection tube to move closer to or away from the packaging bag.

[0015] Furthermore, the injection structure includes: The first connecting seat is fixedly connected to the telescopic arm; The second connecting seat has an injection tube fixedly installed on it, and the second connecting seat is fixedly connected to the first connecting seat.

[0016] Furthermore, the liquid injection structure includes a water receiving plate with several water receiving holes for collecting leaked liquid, and the liquid injection pipe is movably disposed above the water receiving plate.

[0017] A wine dispensing device includes the above-described dispensing structure. Beneficial effects: 1. In this way, the inlet and outlet are set independently. The inlet is used to fill the bag, while the outlet is used to discharge the bag. The inlet is located on the bottom or side of the bag to facilitate connection between the inlet and the matching injection tube. The user only needs to place the bag in the designated position to trigger the connection between the injection tube and the inlet channel to start the injection. After the injection is completed, the container can be removed. The entire injection process does not require the user to hold the bag, thus freeing up the user's hands. By setting a sealing component to seal the inlet, it is ensured that the liquid can only enter the bag during the injection process and cannot flow back. At the same time, the sealing of the packaging bag is ensured during the external transportation process.

[0018] 2. Applying the packaging bag, liquid injection structure, and beer injection equipment in this embodiment to the beer dispensing process of a beer machine, by setting up an inlet, sealing components, and their internal structure, a packaging bag suitable for automatic beer dispensing is formed. The user only needs to place the bag in the designated position, so that the liquid injection tube is connected to the liquid inlet channel, and the packaging bag can automatically receive the beer. After the dispensing is completed, the container can be removed. During the beer dispensing process, the user is completely free of hands, which significantly reduces the complexity of operation and solves the technical problem in related technologies that require the user to operate with both hands during the beer dispensing process, which is extremely inconvenient.

[0019] 3. By setting limiting components and positioning grooves, the positioning grooves are used to accommodate the positioning structure, and the limiting components can limit the positioning structure in the positioning groove to prevent it from falling out of the positioning groove. This facilitates positioning of the packaging bag when it is placed in the injection position before the injection begins, so that the inlet of the packaging bag can be accurately connected with the injection pipe, and a stable connection between the inlet and the injection pipe is maintained during the injection process.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] Example 1 According to an embodiment of this utility model, a packaging bag is provided; please refer to [link / reference]. Figures 1 to 13The bag includes: a bag body 1; a liquid outlet, which is connected to the inside of the bag body 1 and is used to output liquid from the bag body 1; and a liquid inlet 12, which is connected to the inside of the bag body 1. The liquid inlet 12 and the liquid outlet are set independently. The liquid inlet 12 is set on the bottom or side of the bag body 1. A sealing assembly is provided at the liquid inlet 12. The sealing assembly includes a sealing seat 21. A liquid inlet channel 211 is opened in the sealing seat 21. A one-way valve 22 is installed in the liquid inlet channel 211 to allow liquid to flow unidirectionally into the bag body 1 from the outside to the inside.

[0024] Preferably, see Figure 5 The one-way valve 22 is a duckbill valve. The one-way valve 22 can automatically open under liquid pressure, and the liquid flows into the bag body 1 from the outside to the inside in one direction. When there is no external pressure, it remains closed to prevent the liquid inside the bag body from flowing out.

[0025] In this way, the inlet 12 and the outlet are set independently. The inlet 12 is used to complete the liquid inlet, and the outlet is used to complete the liquid outlet. The inlet 12 is set on the bottom or side of the bag body 1 to facilitate the connection between the inlet 12 and its matching injection tube. The user only needs to place the bag body 1 in the designated position to trigger the connection between the injection tube and the inlet channel 211 to start the liquid injection. After the liquid injection is completed, the container can be removed. The entire liquid injection process does not require the user to hold the container, which completely frees the user's hands. By setting a sealing component to seal the inlet 12, it is ensured that the liquid can only enter the bag body 1 during the liquid injection process and cannot flow back. At the same time, the sealing of the packaging bag is ensured during the external transportation process.

[0026] Understandably, the packaging bag can be folded and stored before filling, and after filling, it is lighter than a wine glass, making it more portable. It also has a seal to prevent the liquid from leaking or spilling during transport.

[0027] Applying the packaging bag in this embodiment to the beer dispensing process of a beer machine, by setting the liquid inlet 12, sealing components and their internal structure, a packaging bag suitable for automatic beer dispensing is formed. The user only needs to place the bag body 1 in the designated position, so that the liquid dispensing pipe is connected to the liquid inlet channel 211, and the packaging bag can automatically receive the beer. After the dispensing is completed, the container can be removed. During the beer dispensing process, the user is completely free of hands, which significantly reduces the complexity of operation and solves the technical problem in the related technology that the user needs to operate with both hands during the beer dispensing process, which is extremely inconvenient.

[0028] In some embodiments, a support seat is provided at the bottom of the bag body 1. The support seat is arranged around the periphery of the bottom surface of the bag body and is used to support the entire bag body 1. Since the bag body 1 is made of flexible material, by providing the support seat, the bag body 1 can be prevented from deforming under the pressure of liquid during the liquid injection process, which would affect the liquid injection effect.

[0029] Preferably, the liquid inlet is located on the side of the bag body 1, which provides better sealing and positioning. In this case, the liquid injection tube needs to be matched with the packaging bag to change the extension direction of the liquid injection tube so that the liquid injection tube is located on the side of the packaging bag. The packaging bag in this application can also be selected to have the liquid inlet located on the bottom surface of the bag body 1 according to actual needs. In this case, the liquid injection tube is located on the bottom surface of the packaging bag, which can be used in conjunction with the bottom wine injection device for bottom wine injection.

[0030] In the packaging bag of this embodiment, see Figure 3 The sealing seat 21 includes a limiting component 23, which is located at one end of the sealing seat 21 outside the bag body 1. The limiting component 23 includes a positioning groove 231 formed around the liquid inlet channel 211. By setting the limiting component 23 and the positioning groove 231, the positioning groove 231 is used to accommodate the positioning structure. The limiting component 23 can limit the positioning structure in the positioning groove 231 to prevent it from falling out of the positioning groove 231. This facilitates positioning of the packaging bag when it is placed in the liquid injection position before the liquid injection begins, so that the liquid inlet 12 of the packaging bag can be accurately connected with the liquid injection tube, and a stable connection between the liquid inlet 12 and the liquid injection tube is maintained during the liquid injection process.

[0031] When the liquid inlet is located on the side of the bag body 1, since the bag body 1 is made of flexible material, the aforementioned limiting component 23 and positioning groove 231 are used to prevent the bag body 1 from deforming under the pressure of the liquid by setting the limiting component 23 on the side of the bag body 1.

[0032] In some embodiments, the positioning groove may include two, which are respectively disposed on opposite sides of the outer wall of the sealing seat 21.

[0033] Preferably, the limiting component 23 is a cylindrical structure, and the positioning groove 231 is an annular groove surrounding the outer wall of the sealing seat, and the positioning groove 231 is coaxially arranged with the wine injection channel.

[0034] In the packaging bag of this embodiment, see Figure 1 or Figure 10 The packaging bag includes: a connector 31, which is located at the liquid outlet and has a liquid outlet channel inside, which communicates with the liquid outlet; and a cover 32, which is detachably connected to the connector 31 to close the liquid outlet channel. Thus, by providing the connector 31 and the cover 32, the liquid outlet channel is closed, allowing the user to easily open or close the liquid outlet.

[0035] In the packaging bag of this embodiment, see Figure 4The sealing assembly includes a valve cover 24, which is fitted onto the sealing seat 21. The valve cover 24 is hollow inside and has a flow port 241, which communicates with both the liquid inlet channel 211 and the inside of the bag body 1. By providing the valve cover 24, which is fitted onto the sealing seat 21, the sealing effect of the bag body 1 is further improved, preventing liquid leakage. Through the flow port 241, the liquid output from the liquid inlet channel 211 enters the inside of the bag body 1.

[0036] In some embodiments, the valve cover 24 and the sealing seat 21 are made of food-grade silicone. The valve cover 24 and the sealing seat 21 are provided with interlocking connection structures, which facilitates the assembly of the valve cover 24 onto the sealing seat 21 and increases the connection strength between the valve cover 24 and the sealing seat 21.

[0037] In some embodiments, see Figure 2 From the side view of the bag's structure, the bag adopts a design that is wider at the bottom and narrower at the top, which lowers the overall center of gravity and effectively reduces the possibility of the bag tipping over during use. Preferably, the liquid inlet and sealing components are located on the side of the bag near the bottom, which not only helps to further lower the center of gravity of the bag and improve its stability, but also accelerates the liquid flow rate during the injection process and improves the injection efficiency.

[0038] In some embodiments, a handle 11 is provided at the top of the bag to facilitate carrying the packaging bag.

[0039] Preferably, the liquid outlet is located at the top of the bag body 1.

[0040] In some embodiments, see Figure 6 The valve cover 24 is provided with a fixing groove 252, and the sealing seat 21 is provided with a fixing buckle 251 on the side near the valve cover 24. The fixing buckle 251 and the fixing groove 252 are engaged with each other to ensure a stable connection between the fixing buckle 251 and the fixing groove 252. The number of fixing buckles 251 and fixing grooves 252 can be selected according to the actual situation. For example, the number of fixing buckles 251 and fixing grooves 252 can be set to 2 each.

[0041] In some embodiments, see Figure 7 The limiting component 23 is provided with a process edge, and the installation direction of the entire sealing assembly can be determined according to the direction of the process edge.

[0042] In some embodiments, see Figure 8-9 The sealing seat 21 includes a fixing plate 26 spaced apart from the limiting component 23. The fixing plate 26 is fixedly attached to the bag body 1 and cooperates with the fixing buckle 251 and the fixing groove 252 to fix the sealing seat 21 to the bag body 1.

[0043] In some embodiments, the inlet portion of the bag body 1 needs to be thickened to support the sealing structure such as the sealing seat 21.

[0044] In contrast to filling the packaging bag from the top, in this embodiment, the inlet and sealing assembly are located on the side of the bag near the bottom for filling, thus achieving bottom filling. This results in less foam during the filling process, effectively reducing wine loss and improving filling efficiency and wine utilization.

[0045] Example 2 According to an embodiment of this utility model, a liquid injection structure is provided. Please refer to [link / reference]. Figures 1 to 13 It includes: a packaging bag as described above; a liquid injection tube 4, which carries liquid, and the liquid injection tube 4 cooperates with a one-way valve 22 to connect the liquid injection tube 4 with the liquid inlet channel 211.

[0046] Applying the packaging bag in this embodiment to the beer dispensing process of a beer machine, by setting up a packaging bag and a matching liquid injection tube 4, an automatic dispensing structure is formed. The user only needs to place the bag 1 in the designated position, so that the liquid injection tube is connected to the liquid inlet channel 211, and the packaging bag can automatically receive the beer. After the dispensing is completed, the container can be removed. During the dispensing process, the user is completely free of hands, which significantly reduces the complexity of operation and solves the technical problem in related technologies that require the user to operate with both hands during the beer dispensing process, which is extremely inconvenient.

[0047] In addition, by adopting the above-mentioned automatic wine filling structure, all the delivery pipelines can be hidden inside the equipment, avoiding the wine filling taps or pipelines being exposed outside the equipment. The refrigerated environment inside the equipment ensures the freshness of the wine in the pipelines. When refilling, there is no need to first drain the residual wine in the pipelines, reducing the loss of wine.

[0048] The packaging bag and liquid injection structure in this embodiment can be used not only in the beer dispensing process, but also in the filling process of other alcoholic beverages, carbonated drinks, and regular beverages.

[0049] In the injection structure of this embodiment, see Figure 10 and Figure 12The injection structure includes a support plate 5, which extends perpendicularly to the injection tube 4. An injection groove 51 is formed through the support plate 5, through which the injection tube 4 passes. A positioning part 52 is formed on the support plate 5 surrounding the injection groove 51. The positioning part 52 is abutted against the sealing seat 21 to limit the relative position of the packaging bag and the injection tube 4. Specifically, the positioning groove 231 accommodates the positioning part 52, and the limiting component 23 can limit the positioning part 52 within the positioning groove 231 to prevent it from detaching. Before injection begins, the packaging bag is positioned during the process of placing it into the injection position, ensuring that the inlet 12 of the packaging bag can precisely align with the injection tube, maintaining a stable connection between the inlet 12 and the injection tube during the injection process.

[0050] Preferably, when the positioning groove 231 is an annular groove surrounding the outer wall of the sealing seat, the positioning groove 231 is a U-shaped groove. The opening of the U-shaped groove is used for the limiting component 23 to enter. The setting of the U-shaped groove increases the contact area between the limiting component 23 and the positioning part 52.

[0051] In the injection structure of this embodiment, see Figure 10-11 The liquid injection structure includes a driving component 6, which includes a telescopic arm 61 that is extendable along the extension direction of the liquid injection tube 4. The telescopic arm 61 is drivenly connected to the liquid injection tube 4 and is used to drive the liquid injection tube 4 to move closer to or away from the packaging bag. By setting the driving component 6, the liquid injection tube 4 is controlled to move closer to or away from the packaging bag, thereby completing the connection between the liquid injection tube 4 and the liquid inlet 12.

[0052] Preferably, the driving component is a cylinder, but a driving structure such as a linear motor or a gear and rack mechanism can also be used to control the injection tube 4.

[0053] It should be noted that by setting the limiting component 23 and the positioning groove 231, when the injection tube 4 is connected to the inlet 12, the limiting component 23 and the positioning part 52 are locked together, which can prevent the packaging bag from moving due to the impact of the injection tube 4, and further ensure the positioning effect of the packaging bag.

[0054] Specifically, before starting the wine filling process, during the process of placing the packaging bag into the filling position, the limiting component 23 is aligned and enters the positioning groove 231, and the packaging bag is moved downwards until it reaches the bottom, so that it is in place. The driving component 6 is fixed in the equipment and remains stationary. When the telescopic arm 61 extends towards the packaging bag, it pushes the first connecting seat 62 to move. The first connecting seat 62 then drives the second connecting seat 63 to move. The second connecting seat 63 then drives the injection tube 4 to move towards the injection port of the packaging bag, so that the injection tube 4 is accurately connected to the liquid inlet channel 211, and the wine filling begins. After the wine filling is completed, when the telescopic arm 61 retracts away from the packaging bag, it drives the first connecting seat 62 to retract. The first connecting seat 62 then drives the second connecting seat 63 to move. The second connecting seat 63 then drives the injection tube 4 to move away from the injection port of the packaging bag, so that the injection tube 4 is disconnected from the liquid inlet channel 211. At this time, the packaging bag can be removed.

[0055] In the injection structure of this embodiment, see Figure 10-11 The liquid injection structure includes: a first connecting seat 62, which is fixedly connected to the telescopic arm 61; and a second connecting seat 63, on which the liquid injection pipe 4 is fixedly installed, and which is fixedly connected to the first connecting seat 62. By setting the first connecting seat 62 and the second connecting seat 63, the liquid injection pipe 4 can reciprocate under the control of the drive component 6, ensuring the wine injection function.

[0056] Specifically, the second connecting seat 63 includes a base and a fixed seat. The fixed seat and the base are equipped with an injection pipe 4, an injection solenoid valve 83 for controlling the opening and closing of the injection pipe 4, and a liquid delivery pipe. The first connecting seat 62 is fixedly connected to the base, and the fixed seat and the base are detachably connected.

[0057] Preferably, the injection tube 4 and the support plate 5 are arranged on the side of the packaging bag corresponding to the liquid inlet of the packaging bag, and the water receiving plate 7 is located below the injection tube 4.

[0058] In some embodiments, the injection structure includes a receiving platform for placing the packaging bag to prevent the packaging bag from remaining stationary on the receiving platform during the injection process.

[0059] In the injection structure of this embodiment, see Figure 10-11 The liquid injection structure includes a water receiving plate 7 with several water receiving holes 71 for collecting leaked liquid. An injection pipe 4 is movably positioned above the water receiving plate 7. This design allows the water receiving plate 7 to collect leaked liquid during the injection process, keeping the injection structure clean.

[0060] Example 3 According to an embodiment of this utility model, a wine-pouring device is provided. Please refer to [link / reference]. Figure 13This includes the aforementioned liquid injection structure.

[0061] In the wine-filling device of this embodiment, see Figure 13 The beer-filling equipment includes: a beer-filling line 81, which is connected to both the injection pipe 4 and the beer keg 82; a beer-filling solenoid valve 83, which is installed on the beer-filling line 81 and controls the dispensing of beer from the injection pipe 4; and an intelligent control panel, which is signal-connected to the beer-filling solenoid valve 83. Through these features, the opening and closing of the beer-filling process is controlled. When the beer-filling solenoid valve 83 is opened, beer can be dispensed from the injection pipe 4. The intelligent control panel has a control interface for operating the solenoid valve 83, increasing the automation level of the beer-filling equipment.

[0062] In the wine-filling device of this embodiment, see Figure 13 The beer dispensing equipment includes: a gas supply line 9, which is connected to both a beer keg 82 and a carbon dioxide cylinder 91, and is used to supply carbon dioxide to the beer keg 82; and an anti-carbonation solenoid valve 92, which is installed on the gas supply line 9 and is used to control the gas output from the carbon dioxide cylinder 91. The anti-carbonation solenoid valve 92 is connected to the intelligent control panel. The anti-carbonation solenoid valve 92 controls the entry of carbon dioxide into the distributor on the beer keg 82, ensuring continuous dispensing of the beer.

[0063] In the beer-filling device of this embodiment, when the device has not been operated for a certain period of time, it will automatically close the anti-carbonation solenoid valve 92, cut off the carbon dioxide supply path, and avoid excessive carbonization of beer due to continuous gas supply, thereby effectively maintaining the original taste and quality of beer.

[0064] In some embodiments, the alcohol dispensing device includes an automated cleaning system. When the device accumulates a preset number of dispensing times or the continuous unused time exceeds a set threshold, the system will prompt the user to perform a cleaning operation.

[0065] In some embodiments, cleaning operations are prohibited during the wine pouring process. Depending on the type of glass used, the system has a corresponding wine pouring protection time. If wine pouring is not completed within the set time, the system activates the protection mechanism, automatically stops the pouring, and issues an alarm.
