Description

Technical Field

[0001] This utility model relates to the field of water dispenser manufacturing technology, and more specifically, to a bottle mouth connector and a sparkling water machine. Background Technology

[0002] The related technology provides a sparkling water machine with water injection and gas injection (carbon dioxide gas). The water injection pipe and the gas injection pipe of the sparkling water machine are two separate pipes that enter the water bottle for water injection or gas injection respectively. This water injection and gas injection structure has high requirements for the diameter of the water bottle. A water bottle with a large diameter is required to meet the water injection and gas injection requirements, resulting in a large overall structure of the sparkling water machine.

[0003] If two separate pipes are used to connect to sparkling water machines with universally compatible small-diameter water bottles, then a water filling procedure and an air filling procedure are required. That is, the water bottle is filled with water using the water filling procedure, and then the air filling procedure is used to install it onto the sparkling water machine for air filling, which is a cumbersome operation. Utility Model Content

[0004] The main purpose of this utility model is to provide a bottle mouth connector and a sparkling water machine to solve the problem in the related technology that the water injection pipe and the air injection pipe are respectively adapted to a general-purpose small-diameter water bottle for water injection and air injection operations, which makes the operation cumbersome.

[0005] To achieve the above objectives, according to one aspect of the present invention, a bottle neck connector is provided, comprising: a connector having an interface, the connector being provided with an air injection hole, a water injection hole and an exhaust hole, the exhaust hole communicating with the interior of the interface; an air injection tube connected to the connector and extending through the interface, the interior of the air injection tube communicating with the air injection hole; and a water injection tube connected to the connector and extending through the interface, and sleeved outside the air injection tube, the interior of the water injection tube communicating with the water injection hole.

[0006] Furthermore, the water injection pipe and the air injection pipe are coaxially arranged.

[0007] Furthermore, the lower end of the air injection pipe protrudes beyond the lower end of the water injection pipe.

[0008] Furthermore, the inner wall of the water injection pipe is provided with guide ribs, which extend vertically or spirally from top to bottom.

[0009] Furthermore, there are multiple guide ribs, which are spaced apart along the circumference of the water injection pipe.

[0010] Furthermore, the inlet at the upper end of the water injection pipe is conical.

[0011] Furthermore, the upper end of the water injection pipe is connected to the connector by screwing, clamping, or welding.

[0012] Furthermore, an air outlet is connected to the lower end of the air injection tube, and the diameter of the inner hole of the air outlet is smaller than the diameter of the inner hole of the air injection tube.

[0013] Furthermore, a one-way check valve is installed at the water injection hole.

[0014] Furthermore, the connector includes a connector body and a connecting cover on the upper end of the connector body. The interface is the inner hole of the connector body, and the air injection hole, water injection hole and vent hole are all located on the connecting cover.

[0015] Furthermore, the bottle neck connector also includes a sealing ring, the outer side of which is connected between the connector body and the connecting cap, and the inner side of which extends radially into the interior of the interface. The inner side of the sealing ring is provided with a downwardly extending annular flange.

[0016] According to another aspect of the present invention, a sparkling water machine is provided, including a bottle mouth connector, wherein the bottle mouth connector is the aforementioned bottle mouth connector.

[0017] Furthermore, a first vent pipe is connected to the vent hole of the bottle neck connector, and the sparkling water machine also includes an vent valve disposed on the first vent pipe; and / or, a second vent pipe is connected to the vent hole of the bottle neck connector, and the sparkling water machine also includes a solenoid valve disposed on the second vent pipe; and / or, a third vent pipe is connected to the vent hole of the bottle neck connector, and the sparkling water machine also includes a safety valve disposed on the third vent pipe.

[0018] The bottle neck connector, applying the technical solution of this utility model, includes: a connector, an air injection tube, and a water injection tube. The connector has an interface to which a water bottle can be connected, allowing communication between the interface and the inside of the bottle neck. The connector is provided with an air injection hole, a water injection hole, and an vent hole, with the vent hole communicating with the inside of the interface. The air injection tube is connected to the connector and extends through the interface, with its interior communicating with the air injection hole. The water injection tube is connected to the connector, extends through the interface, and is fitted over the air injection tube, with its interior communicating with the water injection hole. In this way, because the water injection pipe is sleeved outside the air injection pipe, the water injection pipe and air injection pipe are integrated into one unit. This reduces the requirements for the bottle's diameter, making it easier to adapt to common small-diameter water bottles. This allows small-diameter water bottles to simultaneously meet the requirements for water and air injection functions. Compared to existing technologies where water and air injection cannot be integrated and require separate water and air injection operations for each sparkling water bottle, the technical solution of this application solves the problem of related technologies where the water injection pipe and air injection pipe need to be adapted to common small-diameter water bottles for water and air injection operations respectively, and the operation is cumbersome because the positions need to be switched after water injection before air injection. Furthermore, while achieving simultaneous water and air injection operations, the overall structure of the sparkling water machine is also more compact. Attached Figure Description

[0033] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] like Figures 1 to 3 As shown, this application provides a bottle neck connector including: a connector 10, an air injection tube 20, and a water injection tube 30. The connector 10 has an interface 11, on which a water bottle 41 can be connected, so that the interface 11 and the inside of the bottle neck of the water bottle 41 are connected. The connector 10 is provided with an air injection hole 12, a water injection hole 13, and an exhaust hole 14, the exhaust hole 14 being connected to the inside of the interface 11. The air injection tube 20 is connected to the connector 10 and extends out of the interface 11, the inside of the air injection tube 20 being connected to the air injection hole 12. The water injection tube 30 is connected to the connector 10 and extends out of the interface 11, and is sleeved over the air injection tube 20, the inside of the water injection tube 30 being connected to the water injection hole 13.

[0037] The bottle neck connector, using the technical solution of this embodiment, includes: a connector 10, an air injection pipe 20, and a water injection pipe 30. Since the water injection pipe 30 is sleeved outside the air injection pipe 20, integrating the air injection pipe 20 and the water injection pipe 30 together reduces the requirements for the bottle's diameter, making it easier to adapt to common small-diameter water bottles. This allows small-diameter water bottles to simultaneously meet the requirements for water and air injection functions. Compared to existing technologies where water and air injection cannot be integrated and separate water and air injection operations are required for each sparkling water bottle, the technical solution of this embodiment solves the problem that in related technologies, the water injection pipe and air injection pipe need to be separately adapted to common small-diameter water bottles for water and air injection operations, and the operation is cumbersome because the positions need to be switched after water injection before air injection. Furthermore, while achieving simultaneous water and air injection operations, the overall structure of the sparkling water machine is made more compact.

[0038] Furthermore, compared to the wide-mouth water bottles used in the prior art to integrate water and air filling functions in one place and match the sparkling water machine, the sparkling water machine in this embodiment satisfies the universality of small-mouth water bottles, making it easy for users to adapt to existing sparkling water bottles on the market. In addition, small-mouth water bottles have the advantages of better drinking experience and portability compared to wide-mouth water bottles, thus improving the user experience.

[0039] In this embodiment, water enters the water inlet pipe 30 through the water inlet hole 13 and flows into the water bottle along the water inlet pipe 30. The water flows downward and along the outer wall of the air inlet pipe 20. The air inlet pipe 20 plays a guiding role, so that the water flow can maintain a good flow pattern before entering the water bottle. During the water inlet process, the air inside the water bottle will be discharged through the air vent 14 to ensure that the air pressure inside and outside the water bottle is consistent and the water inlet flow rate is not affected.

[0040] like Figures 1 to 3 As shown, in order to further reduce the requirements for the diameter of the water bottle, the water injection pipe 30 and the air injection pipe 20 are coaxially arranged.

[0041] like Figures 1 to 3 As shown, the lower end of the air injection tube 20 protrudes beyond the lower end of the water injection tube 30. Water enters the water injection tube 30 through the water injection hole 13, and flows down the air injection tube 20 towards the bottom of the water bottle. The air injection tube 20 acts as a guide to maintain a good water flow pattern.

[0042] like Figure 3 and Figure 4 As shown, while the air injection pipe 20 serves as a guide, the water injection pipe 30 has a guide rib 31 on its inner wall. The guide rib 31 extends vertically from top to bottom, allowing water to flow down to the bottom of the water bottle along the guide rib 31, further ensuring a better water flow pattern.

[0043] Of course, in the embodiment not shown in the figure, the guide ribs extend spirally from top to bottom.

[0044] like Figure 3 and Figure 4 As shown, there are multiple guide ribs 31, which are spaced apart circumferentially along the water injection pipe 30. In this way, when water flows into the water injection pipe 30, the multiple guide ribs 31 can divide the water flow, making the water bottle smoother and further ensuring a better water flow pattern.

[0045] like Figure 3 and Figure 4 As shown, in order to collect the water entering the water injection pipe 30 from the water injection hole 13, the inlet 32 ​​at the upper end of the water injection pipe 30 is conical.

[0046] like Figure 3 As shown, for ease of installation, the upper end of the water injection pipe 30 is welded to the connector 10.

[0047] Of course, in embodiments not shown in the figure, the upper end of the water injection pipe is connected to the connector by screwing or welding.

[0048] like Figures 1 to 3 As shown, in order to ensure that the gas entering the gas injection pipe 20 from the gas injection port 12 has sufficient injection pressure and improve the gas injection efficiency, a gas outlet 40 is connected to the outlet 21 at the lower end of the gas injection pipe 20. The diameter of the inner hole of the gas outlet 40 is much smaller than the diameter of the inner hole of the gas injection pipe 20.

[0049] After water filling is completed, press the operating lever to inject carbon dioxide gas into the water bottle 41 through the gas injection pipe, and at the same time close the vent 14. The carbon dioxide gas is injected into the liquid in the water bottle through the gas outlet 40 at the bottom of the gas injection pipe 20. The outlet of the gas outlet 40 is located below the water surface, and the inner diameter of the gas outlet 40 is much smaller than the inner diameter of the gas injection pipe 20. This ensures that the pressure of the gas output from the gas outlet 40 is sufficient to fill the liquid in the water bottle during gas injection, ensuring sufficient gas injection pressure for the sparkling water machine and improving gas injection efficiency.

[0050] like Figures 1 to 3 As shown, a one-way check valve is installed at the water injection hole 13. The one-way check valve ensures that gas cannot enter the water circuit through the water injection pipe 30 during the gas injection process.

[0051] like Figures 1 to 3 As shown, in order to facilitate the setting of air injection hole 12, water injection hole 13 and vent hole 14 on the connector 10, the connector 10 includes a connector body 15 and a connecting cover 16 covering the upper end of the connector body 15. The interface 11 is the inner hole of the connector body 15, and the air injection hole 12, water injection hole 13 and vent hole 14 are all set on the connecting cover 16.

[0052] like Figures 1 to 3As shown, the bottle neck connector also includes a sealing ring 50. The outer side of the sealing ring 50 is connected between the connector body 15 and the connecting cap 16, and the inner side of the sealing ring 50 extends radially into the interior of the interface 11. The water bottle 41 is connected to the interface 11, and the inner side of the sealing ring 50 can extend into the bottle neck of the water bottle 41, thus sealing the bottle neck and preventing gas entering the water bottle 41 from leaking between the connector body 15 and the connecting cap 16. Furthermore, the inner side of the sealing ring 50 is provided with a downwardly extending annular flange 51. The annular flange 51 can fit against the inner wall of the bottle neck of the water bottle 41, preventing gas entering the water bottle 41 from leaking from the interface 11.

[0053] This application also provides a sparkling water machine, such as Figures 1 to 5 As shown, the sparkling water machine includes a bottle neck connector, which is the aforementioned bottle neck connector. Because the aforementioned bottle neck connector solves the problem in related technologies where the water injection pipe and air injection pipe are respectively adapted to universally sized small-diameter water bottles for water injection and air injection operations, resulting in cumbersome operation, the sparkling water machine with this bottle neck connector can solve the same technical problem.

[0054] In this embodiment, the sparkling water machine further includes: a gas cylinder, a water bottle, an injection line, and an operating lever. The gas cylinder is mounted on the connector 10. The water bottle is detachably mounted on the interface 11 of the connector 10. The injection line connects the gas cylinder and the water bottle. The operating lever is movably mounted on the connector 10 and has a first open position for connecting the injection line to the gas cylinder and the water bottle, and a first closed position for disconnecting the injection line from the gas cylinder and the water bottle. The injection line is connected to the injection port 12.

[0055] The gas injection line includes an inlet that connects to the gas injection port 12 and an outlet that connects to the mouth of the water bottle. A needle valve is installed at the inlet. The end of the operating lever furthest from the water bottle drives the needle valve to open or close the inlet. When the operating lever is in the first open position, the needle valve opens the inlet to connect the gas injection line, facilitating connection between the gas cylinder and the water bottle. When the operating lever is in the first closed position, the needle valve closes the inlet to disconnect the gas injection line, facilitating disconnection between the gas cylinder and the water bottle.

[0056] The sparkling water machine also includes a first exhaust pipe 61 connected to the exhaust port 14 and an exhaust valve disposed on the first exhaust pipe 61. The operating lever also has a second open position for driving the exhaust valve to connect to the first exhaust pipe 61 and a second closed position for driving the exhaust valve to block the first exhaust pipe 61. The operating lever is simultaneously in the first open position and the second closed position, or simultaneously in the first closed position and the second open position.

[0057] like Figures 1 to 5As shown, a first vent pipe 61 is connected to the vent hole 14 of the bottle neck connector. The sparkling water machine also includes a vent valve 71 installed on the first vent pipe 61. During water filling, the vent valve 71 opens the first vent pipe 61, allowing the environment inside the water bottle to connect with the external environment through the first vent pipe 61, ensuring consistent air pressure inside and outside the water bottle. After water filling, pressing the operating lever closes the vent valve 71, preventing gas leakage during filling. A second vent pipe 62 is connected to the vent hole 14 of the bottle neck connector. The sparkling water machine also includes a solenoid valve 72 installed on the second vent pipe 62. Because the inner diameter of the first vent pipe 61 is small, to prevent insufficient gas exhaust during water filling due to a high water flow rate, a solenoid valve is installed on the second vent pipe 62. The solenoid valve opens simultaneously with water filling, venting synchronously with the first vent pipe 61 to meet the requirements of high-flow-rate water filling. The solenoid valve closes when water filling is complete and remains in a normally closed state. A third vent pipe 63 is connected to the vent hole 14 of the bottle mouth connector. The sparkling water machine also includes a safety valve 73 installed on the third vent pipe 63. The function of the safety valve is to open when the air pressure inside the water bottle reaches a certain value during the filling process, preventing excessive air pressure inside the water bottle from causing safety hazards. Two safety valves can be set, one opening when the pressure reaches 8 bar and the other opening when the pressure reaches 16 bar.

[0058] Of course, in embodiments not shown in the figures, a first vent pipe is connected to the vent hole of the bottle neck connector, and the sparkling water machine also includes a vent valve disposed on the first vent pipe. Alternatively, a second vent pipe is connected to the vent hole of the bottle neck connector, and the sparkling water machine also includes a solenoid valve disposed on the second vent pipe. Alternatively, a third vent pipe is connected to the vent hole of the bottle neck connector, and the sparkling water machine also includes a safety valve disposed on the third vent pipe.

[0059] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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 on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0061] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0062] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
