Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a liquid storage container and a tea bar machine. Background Art

[0002] A tea bar machine is a new type of drinking water device, typically featuring multiple temperature settings and suitable for brewing tea, coffee, powdered milk, and more. In related technologies, by adding a liquid storage container filled with various additives, such as juice or coffee, to the tea bar machine's water path, the machine can also brew rich juice drinks or aromatic, full-bodied coffee. Traditional liquid storage containers typically consist of a bottle body and a cap. The bottle body holds the liquid, while the cap seals the bottle mouth to prevent leakage. Traditional liquid storage containers offer advantages such as simple structure, ease of manufacture, and low cost.

[0003] However, existing traditional liquid storage containers present several issues. In particular, when extracting liquid from the bottle opening, users must manually install a pressure-balancing device on the bottle opening to facilitate extraction. This process is relatively cumbersome, requiring additional installation steps and inconvenient. Furthermore, for traditional liquid storage containers that don't have a pressure-balancing device, users must purchase one separately to extract the liquid, significantly impacting the user experience. Utility Model Content

[0004] In response to the problem that when extracting liquid from traditional liquid storage containers, an air pressure balancing device needs to be manually installed in order to smoothly extract the liquid, the utility model proposes a liquid storage container with a simple structure. Not only does it not require the additional installation of an air pressure balancing device, but it can also achieve smooth liquid extraction and solve the problems of fluency and precision that may arise when extracting liquid from traditional containers, thereby improving operational convenience and accuracy of liquid extraction.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] In a first aspect, a liquid storage container is provided, comprising a bottle body and a bottle cap, wherein the bottle body has a bottle mouth, a sealing plate is connected to the top of the bottle mouth to cover the bottle mouth, the bottle cap is arranged on a side of the sealing plate facing away from the bottle body, and an outlet for liquid outflow is opened at the bottom of the bottle body;

[0007] A hollow sealing column is protruding from the bottom of the sealing plate, and the sealing column is located in the bottle mouth. The sealing plate is provided with a first communication hole connected to the sealing column, the bottle cap is provided with a second communication hole connected to the first communication hole, and the side wall of the sealing column is provided with a third communication hole connected to the interior of the bottle body, and the second communication hole is movably connected to a press cover;

[0008] The bottom of the pressing cover is connected to a closing column for closing the third connecting hole, the closing column is slidably connected to the sealing column, and a return member is provided in the sealing column for driving the closing column to close the third connecting hole; when the pressing cover presses the closing column to move the side wall of the closing column away from the third connecting hole and open the third connecting hole, the third connecting hole is connected to the external atmosphere.

[0009] With the above technical solution, when liquid needs to be extracted, the pressing cover is pressed, and the pressing cover drives the closing column to open the third connecting hole, so that the atmosphere is connected to the third connecting hole, and then the atmospheric pressure pushes the liquid to be discharged from the outlet. Through the above setting, the user does not need to install an additional air pressure balancing device when extracting liquid, and can achieve smooth outflow of liquid by simply pressing the cover, which greatly improves the convenience of use and user experience; at the same time, the design of the outlet at the bottom of the bottle body enables smooth extraction of liquid, solving the problems of fluency and accuracy in liquid extraction from traditional containers.

[0010] Preferably, the side wall of the pressing cover is provided with at least one connecting hole, and the top of the pressing cover is provided with at least one air hole. When the pressing cover presses the closing column to move the side wall of the closing column away from the third connecting hole and opens the third connecting hole, the third connecting hole is connected to the atmosphere through the connecting hole.

[0011] By adopting the above technical solution, when liquid needs to be extracted, the pressing cover is pressed, and the pressing cover drives the closing column to open the third connecting hole, and the third connecting hole is connected with the connecting hole, and the atmosphere is connected with the third connecting hole. Then the atmospheric pressure pushes the liquid to be discharged from the outlet. Through the setting of the connecting hole, the speed of the third connecting hole connecting with the atmosphere is accelerated. By pressing the pressing cover, the liquid in the liquid storage container will be extracted from the liquid storage container faster, thereby improving the liquid extraction efficiency, reducing the operation time, and improving the convenience and efficiency of use.

[0012] Preferably, the aperture of the second connecting hole is smaller than the aperture of the first connecting hole, and a limiting ring protrudes from the outer wall of the bottom of the pressing cover. The outer diameter of the limiting ring is larger than the aperture of the second connecting hole, and the outer diameter of the limiting ring is not larger than the outer diameter of the closing column.

[0013] The aforementioned technical solution utilizes a protruding retaining ring on the outer side of the bottom of the push-on cover to limit its range of movement, reducing the risk of the cover or closure column being pulled away from the bottle due to the return element returning to its original position too quickly. This design ensures the stability and safety of the liquid storage container during use, reduces the likelihood of accidents, and improves product reliability and user experience.

[0014] Preferably, the outer side wall of the closing column is provided with a first sealing ring for sealing the gap between the closing column and the sealing column, and when the limiting ring abuts against the bottle cap, the first sealing ring is located above the third communicating hole.

[0015] By adopting the above technical solution, by setting a first sealing ring on the outer wall of the closing column, when the limiting ring abuts against the bottle cap, the first sealing ring can effectively seal the gap between the closing column and the sealing column, preventing gas from leaking from the sealing column, and thus causing water leakage at the outlet.

[0016] Preferably, the outer side wall of the closing column is further provided with a second sealing ring for sealing the gap between the closing column and the sealing column. When the limiting ring abuts against the bottle cap, the second sealing ring is located below the third communicating hole.

[0017] The above technical solution ensures that the liquid storage container can be better sealed when not in use, reduces liquid leakage, and helps to reduce the situation where liquid flows into the interior of the sealing column from the third connecting hole due to shaking of the bottle.

[0018] Preferably, the first communicating hole extends obliquely downward toward the inner side wall of the sealing column at one end close to the bottle cap.

[0019] With the above technical solution, by angling the first communication hole toward the inner side of the sealing post, workers can more easily insert or connect the sealing post into the first communication hole when installing the liquid reservoir. This design can reduce the difficulty of operation during installation and improve installation efficiency and convenience.

[0020] Preferably, the bottom of the closing column is connected to a guide column, and the inner side of the bottom of the sealing column is connected to a guide rail that cooperates with the guide column.

[0021] By adopting the above technical solution, the coordinated design of the guide column and the guide rail can effectively guide the movement trajectory of the closing column, so that the closing column remains vertical and stable during the closing process, and reduces the deviation or instability of the closing column during the movement.

[0022] Preferably, the bottle cap is detachably connected to the outer periphery of the bottle mouth.

[0023] The above technical solution, by designing a detachable connection between the bottle cap and the outer periphery of the bottle mouth, allows the user to easily remove or replace the bottle cap, thereby conveniently cleaning the bottle cap and the bottle mouth. In addition, this detachable connection design also makes the liquid reservoir easier to maintain and service, extending its service life.

[0024] Preferably, the sealing plate is detachably connected to the top of the bottle mouth.

[0025] By adopting the above technical solution, when it is necessary to clean or repair the inside of the sealing column, the user only needs to simply remove the sealing plate and can easily enter the inside of the sealing column to perform cleaning or repair operations.

[0026] In a second aspect, a tea bar machine is provided, which includes a water outlet pipe and the above-mentioned liquid storage container, and the water outlet pipe and the outlet of the liquid storage container are connected to each other.

[0027] In summary, the present invention has the following beneficial effects:

[0028] When liquid needs to be extracted, the user presses the pressing cover, and the pressing cover drives the closing column to open the third connecting hole, so that the atmosphere is connected to the third connecting hole, and the atmospheric pressure will immediately push the liquid to be discharged from the outlet. The user does not need to install an additional air pressure balancing device when extracting liquid, and can achieve smooth outflow of liquid by simply pressing the cover. Therefore, the utility model proposes a liquid storage container with a simple structure, which not only does not require the installation of an additional air pressure balancing device, but also can achieve smooth extraction of liquid, and can solve the problems of fluency and precision that may occur when extracting liquid from traditional containers, thereby improving the convenience of operation and the accuracy of liquid extraction.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0039] See also Figure 1 、 Figure 2 as well as Figure 3The present invention discloses a liquid storage container comprising a bottle body 1 and a bottle cap 2. The bottom of the bottle body 1 is provided with an outlet 12 for liquid outflow, the bottle body 1 has a bottle mouth 11, and a sealing plate 3 is provided on the top of the bottle mouth 11 for covering the bottle mouth 11. The bottle cap 2 is provided on the side of the sealing plate 3 facing away from the bottle body 1. A hollow sealing post 4 protrudes from the center of the bottom wall of the sealing plate 3. The sealing post 4 is located within the storage bottle. The sealing plate 3 has a first communication hole 31 in communication with the sealing post 4. The bottle cap 2 has a second communication hole 21 in communication with the first communication hole 31. A third communication hole 41 in communication with the interior of the bottle body 1 is provided on the side wall of the sealing post 4. A pressing cover 5 is slidably connected to the second communication hole 21. A closing post 6 for closing the third communication hole 41 is fixedly connected to the bottom of the pressing cover 5. The closing post 6 is slidably connected to the sealing post 4. A return member 7 is installed within the sealing post 4 for driving the closing post 6 to close the third communication hole 41. When it is necessary to extract liquid, the pressing cover 5 on the bottle cap 2 is pressed by hand, and the pressing cover 5 pushes the closing column 6 to move away from the bottle cap 2, so that the closing column 6 is away from the third communicating hole 41, the third communicating hole 41 is opened, and the third communicating hole 41 is connected to the atmosphere. At this time, the air pressure pushes the liquid to be discharged from the outlet 12; when the liquid is extracted, the pressing cover 5 is released, and the return member 7 drives the closing column 6 to move towards the bottle cap 2, so that the closing column 6 closes the third communicating hole 41, thereby stopping the liquid from being discharged from the outlet 12.

[0040] Specifically, the bottle cap 2 can be detachably connected to the bottle mouth 11 by means of a snap connection or a threaded connection, so that the bottle cap 2 can be easily removed to allow the bottle body 1 to be connected with other structures. The bottle cap 2 can cover the outer periphery of the bottle mouth 11 and the sealing plate 3, or the bottle cap 2 can only cover the sealing plate 3.

[0041] Specifically, the pressing cover 5 and the closing column 6 can be formed separately or integrally, and can be arranged as needed.

[0042] Specifically, the return member 7 can be a compression spring, which is arranged between the inner wall of the bottom of the closing column 6 and the bottom wall of the sealing column 4. In other cases, the return member 7 can also be a tension spring.

[0043] Preferably, at least one air hole 51 is provided on the top of the pressing cover 5. At least one connecting hole 52 is provided on the side wall of the pressing cover 5, and the third connecting hole 41 is connected to the atmosphere through the connecting hole 52. When liquid needs to be extracted, the pressing cover 5 on the bottle cap 2 is pressed by hand, and the pressing cover 5 pushes the closing column 6 to move in a direction away from the bottle cap 2, so that the closing column 6 is away from the third connecting hole 41, and the third connecting hole 41 opens and is connected to the connecting hole 52. At this time, the air pressure pushes the liquid to be discharged from the outlet 12. By using the connecting hole 52 to connect the third connecting hole 41 with the atmosphere, that is, the air hole 51, the internal space of the pressing cover 5, the connecting hole 52 and the third connecting hole 41 are connected in sequence, the speed at which the atmosphere flows into the third connecting hole 41 can be accelerated, thereby improving the efficiency of liquid extraction, reducing the operation time, and improving the convenience and efficiency of use.

[0044] See also Figure 3 as well as Figure 5 The diameter of the second connecting hole 21 is smaller than that of the first connecting hole 31. A limiting ring 53 protrudes from the outer sidewall of the bottom of the pressing cover 5. The outer diameter of the limiting ring 53 is larger than the diameter of the second connecting hole 21 and no larger than the outer diameter of the closing post 6. In this embodiment, the outer diameter of the limiting ring 53 is equal to the outer diameter of the closing post 6. In this embodiment, the return element 7 is a spring, one end of which is fixedly connected to the inner sidewall of the bottom of the sealing post 4 and the other end is fixedly connected to the bottom of the closing post 6. The spring constantly drives the closing post 6 toward the bottle cap 2. In some embodiments, the return element 7 can be a pneumatic or hydraulic element. When liquid needs to be extracted, the pressing cover 5 on the bottle cap 2 is manually pressed, and the closing post 6 compresses the spring, causing it to be compressed. After the liquid is extracted, the pressing cover 5 is released, and the spring restores its elastic force, driving the closing post 6 toward the bottle cap 2, thereby sealing the third connecting hole 41.

[0045] See also Figure 3 as well as Figure 5 The outer wall of the closing column 6 is fixedly connected with a first sealing ring 61 for sealing the gap between the closing column 6 and the sealing column 4. When the limiting ring 53 abuts against the bottle cap 2, the first sealing ring 61 is located above the third communicating hole 41. The first sealing ring 61 effectively seals the gap between the closing column 6 and the sealing column 4, preventing gas from leaking from the sealing column 4, thereby reducing the occurrence of water leakage from the outlet 12. The outer wall of the closing column 6 is also fixedly connected with a second sealing ring 62 for sealing the gap between the closing column 6 and the sealing column 4. When the limiting ring 53 abuts against the bottle cap 2, the second sealing ring 62 is located below the third communicating hole 41. The provision of the second sealing ring 62 ensures that the liquid storage container can be sealed when not in use to prevent liquid leakage. Only when the liquid storage container needs to be used, pressing the pressing cover 5 will open the third communicating hole 41 to allow the liquid to flow out. This design not only reduces the water leakage problem, but also ensures the safe storage and use of the liquid.

[0046] See also Figure 4 as well as Figure 5 The end of the first communication hole 31 near the bottle cap 2 extends obliquely downward toward the inner sidewall of the sealing column 4. A guide post 8 is fixedly connected to the bottom of the sealing column 6, and a guide rail 9 is fixedly connected to the inner side of the bottom of the sealing column 4, which cooperates with the guide post 8. The cooperation between the guide post 8 and the guide rail 9 effectively guides the movement trajectory of the sealing column 6, ensuring that the sealing column 6 remains vertical and stable during the sealing process, and reducing the possibility of displacement or instability of the sealing column 6 during movement.

[0047] The implementation principle of this embodiment is:

[0048] When liquid needs to be extracted, the pressing cover 5 is pressed, and the pressing cover 5 pushes the closing column 6 to move away from the bottle cap 2. The closing column 6 opens the third connecting hole 41, and the closing column 6 compresses the spring. At this time, the atmosphere will flow from the air hole 51 through the connecting hole 52 to the third connecting hole 41, and the atmospheric pressure pushes the liquid out of the outlet 12.

[0049] When the extraction is completed, the pressing cover 5 is released, the spring restores its elastic force, and the spring pushes the closing column 6 to move toward the bottle cap 2, so that the positioning ring abuts against the bottle cap 2, the closing column 6 closes the third connecting hole 41, and the closing column 6 is located between the first sealing ring 61 and the second sealing ring 62, stopping the liquid from flowing out of the outlet 12.

[0050] The embodiment of the present application also provides a tea bar machine (not shown in the figure), which includes a water outlet pipe and the above-mentioned liquid storage container. The water outlet pipe and the outlet 12 of the liquid storage container are connected to each other. After the added liquid stored in the liquid storage container enters the water outlet pipe of the tea bar machine through the outlet 12, it can be mixed with the water in the water outlet pipe to brew a rich-tasting fruit juice drink or a rich and mellow coffee, which can greatly enrich the user's drinking experience.

[0051] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
