[0032] The following further illustrates the detailed implementation manners of the present utility model with reference to the drawings.

[0033] It is easy to understand that according to the technical solution of the present utility model, without changing the essence of the present utility model, various structural forms and implementation manners that can be mutually replaced by those of ordinary skill in the art. Therefore, the following detailed implementation manners and drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as all of the present utility model or as a limitation or restriction on the technical solution of the utility model.

[0035] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "attachment" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] Compared with ordinary water purifiers, the built-in water purifier has the advantages of high integration and space saving, and can be installed in places such as kitchen cabinets and office pantry areas. In related technologies, when adding a liquid storage container filled with various additives such as juice and coffee to the water path of the built-in water purifier, the built-in water purifier can also brew fruit juice drinks with rich flavors or strong and mellow coffee, further enriching the performance of the built-in water purifier.

[0037] In the current field of liquid storage containers, traditional designs usually include a bottle body and a lid, and users draw liquid through an opening on the lid. However, there are some challenges in the process of drawing liquid with this design, especially when the liquid cannot flow smoothly or an additional air pressure balancing device is required. To solve these problems, some existing technologies adopt air pressure balancing techniques, but this often requires adding additional components or devices, complicating the structure of the container, and not all containers are equipped with these devices. As a result, existing storage containers usually cannot well balance simplicity of structure and smoothness of liquid discharge.

[0038] To solve the above problems, please refer to Figures 1 to 4 , some embodiments of the present utility model provide a liquid storage container, which includes a bottle body 1, a pressing member 2, and an elastic member 3. Among them, the bottle body 1 has a liquid storage cavity 12, a sealing cavity 11, a first opening 13 connecting the liquid storage cavity 12 and the sealing cavity 11, a second opening 14 connecting the sealing cavity 11 and the outside of the bottle body 1, and an outlet 15 connecting the liquid storage cavity 12 and the outside of the bottle body 1. The pressing member 2 is movably sleeved in the first opening 13 and the second opening 14. The pressing member 2 has a breathable hole 21, a lid inner cavity 22, and a communication hole 23 that are sequentially connected. The pressing member 2 can be switched from a closed position to an open position under external pressing. As Figure 4 shown, in the closed position, the communication hole 23 and the liquid storage cavity 12 are isolated from each other, and in the open position (not shown in the figure), the communication hole 23 and the liquid storage cavity 12 are in communication with each other. The elastic member 3 is used to provide an elastic restoring force for the pressing member 2 to enable the pressing member 2 to return from the open position to the closed position.

[0039] In the liquid storage container provided in this embodiment, when the pressing member 2 is not subjected to an external force, the pressing member 2 is in the closed position, the communication hole 23 of the pressing member 2 and the liquid storage chamber 12 are isolated from each other, and the liquid storage chamber 12 is in a closed state. When the pressing member 2 is pressed by an external force, the pressing member 2 is in the open position, and the liquid storage chamber 12, the communication hole 23 on the pressing member 2, the inner cavity 22 of the cap, and the vent hole 21 on the pressing member 2 are communicated in sequence, that is, the liquid storage chamber 12 is indirectly communicated with the external atmosphere. At this time, the liquid in the liquid storage chamber 12 can be drawn out more smoothly from the outlet 15 at the bottom of the bottle body 1; the liquid storage container provided by the present invention does not require an additional air pressure balancing device, and the structure is relatively simple; moreover, it solves the problem of possible fluidity during liquid extraction of traditional containers, improving the operation convenience and the accuracy of liquid extraction.

[0040] In some embodiments of the present invention, please refer to Figure 4 , the liquid storage container further includes a sealing ring 4. A limiting member 5 surrounding the first opening 13 is convexly provided on the cavity wall of the sealing cavity 11. The sealing ring 4 is used to seal the gap between the inner wall of the limiting member 5 and the outer wall of the pressing member 2.

[0041] In the embodiment of the present application, the sealing ring 4 is provided between the outer wall of the pressing member 2 and the inner wall of the limiting member 5. When the pressing member 2 is in the closed position, the sealing ring 4 can isolate the sealing cavity 11 and the liquid storage chamber 12, and can effectively seal the liquid storage chamber 12, thereby preventing external air and pollutants from entering the liquid storage chamber 12 through the sealing cavity 11 and maintaining a pure environment in the liquid storage chamber 12. Moreover, the pressing action of the limiting member 5 ensures that the sealing ring 4 is firmly fixed to the outer periphery of the pressing member 2, preventing the sealing ring 4 from loosening or shifting due to external pressure or vibration, and improving the service life and stability of the sealing ring 4.

[0042] Specifically, when the bottle body 1 includes the bottle body 101, the support base 102, and the bottle cap 103 described below, and the pressing member 2 includes the pressing cap and the central column 202 described below, the sealing ring 4 can be installed between the inner wall of the limiting member 5 and the outer wall of the central column 202.

[0043] In some embodiments of the present invention, please refer to Figure 4 , a pressing member 6 for pressing the sealing ring 4 is provided at the top of the limiting member 5.

[0044] Specifically, the top clamping member 6 of the limiter 5 may be integrally formed with the limiter 5, or may be an independent part. Regardless of being integrally formed or an independent part, the clamping member 6 will be located at the top of the limiter 5 to ensure that the applied pressure can be evenly transmitted to the sealing ring 4. By compressing the sealing ring 4, it is ensured that the gap between the limiter 5 and the pressing member 2 is fully filled, thereby improving the sealing performance of the sealing chamber 11, preventing liquid leakage and contaminants from entering the sealing chamber 11 and leaking, and also preventing contaminants in the external air from entering. The top clamping member 6 of the limiter 5 can provide appropriate pressure to keep the sealing ring 4 in a stable position and not easily loosen or shift, thereby enhancing the stability and reliability of the entire system.

[0045] In some embodiments of the present invention, the pressing member 6 and the limiting member 5 are detachably connected.

[0046] Specifically, the clamping member 6 and the stopper 5 are designed to be detachably connected, which means that they can be easily separated without using excessive force or special tools. The detachable connection allows maintenance personnel to easily remove and reinstall the clamping member 6 and the stopper 5, thereby facilitating maintenance and repair of the liquid storage container. If the clamping member 6 or the stopper 5 needs to be replaced, the detachable connection allows the user to easily replace the parts without replacing the entire device, reducing maintenance costs and time. The user can easily separate the clamping member 6 and the stopper 5 for thorough cleaning and disinfection, thereby ensuring the hygiene and safety of the liquid storage container.

[0047] See also Figure 3 and Figure 4 In some embodiments of the present invention, the bottle 1 includes a bottle body 101, a support base 102 and a bottle cap 103. The bottle body 101 has an open mouth, the support base 102 is covered on the open mouth and encloses the bottle body 101 to form a liquid storage cavity 12; the middle part of the support base 102 is concave toward the liquid storage cavity 12, and the support base 102 is provided with a first opening 13; the bottle cap 103 is covered on the side of the support base 102 away from the bottle body 101 and encloses the support base 102 to form a sealed cavity 11, and the bottle cap 103 is provided with a second opening 14.

[0048] Specifically, the support base 102 and the bottle body 101 can be connected by welding, clamping, etc., and the bottle cap 103 and the bottle body 101 can be connected by snap connection, threaded connection, etc.

[0049] The liquid storage container provided in this embodiment has a bottle body 1 including a bottle body 101, a support base 102, and a bottle cap 103. The bottle body 101, the support base 102, and the bottle cap 103 are integrally formed separately, which can simplify the preparation process of the bottle body 1. When the bottle cap 103 and the bottle body 101 are set to be detachably connected, during the transportation and storage of the liquid storage container, the bottle cap 103 and the bottle body 101 can be kept connected, so that the liquid storage container is in a closed state. When using the liquid storage container, the bottle cap 103 can be detached, and then a driving structure is used to drive the pressing member 2 to switch the pressing member 2 from the closed position to the open position and maintain it in the open position or the closed position, so that the liquid storage container can be applied to an automatic liquid discharging system, simplifying the operation steps and improving the use convenience.

[0050] In some embodiments of the present utility model, the bottle body 101 is set as a rigid bottle body. With this setting, the bottle body 101 can better protect the liquid in the liquid storage cavity 12, and the transportation is also more convenient. In addition, compared with using a soft packaging bag as the bottle body 101, although the soft packaging bag theoretically does not require additional air pressure balance, the soft packaging bag is prone to self-compression, resulting in negative pressure inside the liquid storage cavity 12, affecting the accuracy and efficiency of liquid extraction. The rigid bottle body can improve the above problems and enhance the accuracy and efficiency of liquid extraction.

[0051] In some embodiments of the present utility model, the pressing member 2 includes a cover body 201 and a central column 202 that enclose to form a cover inner cavity 22. The cover body 201 is movably sleeved on the second opening 14 and is provided with a ventilation hole 21. The central column 202 is movably sleeved on the first opening 13 and is provided with a communication hole 23. The maximum outer diameter of the cover body 201 is greater than the maximum outer diameter of the central column 202. The elastic member 3 abuts between the end face of the cover body 201 facing the central column 202 and the cavity wall of the sealing cavity 11.

[0052] Specifically, the maximum outer diameter of the cover body 201 is greater than the maximum outer diameter of the central column 202, which can be understood as that one end of the cover body 201 close to the central column 202 forms an end face for the elastic member 3 to abut. For example, when the cross-section of the cover body 201 and the cross-section of the central column 202 are both circular, the outer diameter of the cover body 201 is greater than the outer diameter of the central column 202. Another example is that when the cross-section of the cover body 201 is square and the cross-section of the central column 202 is circular, the side length of the cover body 201 is greater than the outer diameter of the central column 202.

[0053] The cover body 201 and the central column 202 can be integrally formed, or the cover body 201 and the central column 202 can be integrally formed separately, or part of the structure of the cover body 201 and the central column 202 can be integrally formed. For example, as Figure 5As shown, the cover body 201 includes a first cylindrical body 2011 with an open bottom and a plate-shaped ring 2012. The central column 202 is a second cylindrical body 2021 with an open top. The bottom of the first cylindrical body 2011 is connected to the outer side of the plate-shaped ring 2012, and the top of the second cylindrical body 2021 is connected to the inner side of the plate-shaped ring 2012. The second cylindrical body 2021 and the plate-shaped ring 2012 are integrally formed, and the inner wall of the plate-shaped ring 2012 and the first cylindrical body 2011 are in mutual contact.

[0054] Specifically, the air holes 21 can be provided on the top wall and / or the side wall of the cover body 201, and the number of the air holes 21 can be set to one or more. For example, a plurality of uniformly arranged air holes 21 are provided on the top wall of the cover body 201. The communication holes 23 are provided on the side wall of the central column 202, and the number of the communication holes 23 can be one or more. The communication holes 23 can be set as capillary holes. When the pressing member 2 is in the closed position, the sealing ring 4 can directly seal the communication holes 23, and the sealing ring 4 can also make the communication holes 23 communicate with the sealing cavity 11 by being located on the side of the communication holes 23 close to the liquid storage cavity 12, so as to achieve the effect of separating the liquid storage cavity 12 and the sealing cavity 11.

[0055] In the liquid storage container provided in this embodiment, the pressing member 2 includes a cover body 201 and a central column 202. The maximum outer diameter of the pressing member 2 is greater than the maximum outer diameter of the central column 202, so that an end surface for the elastic member 3 to abut against can be formed at one end of the pressing member 2 close to the central column 202, making the installation of the elastic member 3 more convenient. Moreover, setting the outer diameter of the cover body 201 to be larger can facilitate pressing the cover body 201, and setting the outer diameter of the central column 202 to be smaller can reduce the sealing difficulty between the central column 202 and the limiting member 5, making the sealing performance of the liquid storage cavity 12 better. In addition, when the cover body 201 and the central column 202 are separately provided, it is convenient to manufacture the pressing member 2.

[0056] In some embodiments of the present utility model, the elastic member 3 is sleeved on the outer circumferences of the central column 202 and the limiting member 5.

[0057] Specifically, the elastic member 3 can be set as structures such as a spring or an elastic silicone sleeve, and can be set according to needs.

[0058] In the liquid storage container provided in this embodiment, setting the elastic member 3 to be sleeved on the outer circumferences of the central column 202 and the limiting member 5 makes the stability of the elastic member 3 better, and enables the elastic member 3 to provide a relatively stable and uniform elastic restoring force for the pressing member 2, so that the pressing member 2 can be pressed and bounced back smoothly.

[0059] In some embodiments of the present utility model, please refer to Figure 4 , when the pressing member 2 is in the closed position, the top of the pressing member 2 protrudes beyond the second opening 14.

[0060] The top of the pressing member 2 protrudes beyond the second opening 14, enabling the user to easily grasp or press the pressing member 2 from the second opening 14 when the pressing member 2 is in the closed position, facilitating the user's opening, closing, or pressing operations. Since the top of the pressing member 2 protrudes beyond the second opening 14, the user can clearly see the position of the pressing member 2, which helps the user quickly identify and operate the liquid storage container.

[0061] In some embodiments of the present utility model, please refer to Figure 4 , a step 7 is convexly provided on the outer wall of the pressing member 2, and the step 7 is used to prevent the pressing member 2 from disengaging from the sealing cavity 11 through the second opening 14.

[0062] Specifically, when the pressing member 2 includes a cover body 201 and a central column 202, the step 7 can be provided on the cover body 201 or the central column 202. When the pressing member 2 is in the closed position, the step 7 abuts against the cavity wall of the sealing cavity 11 surrounding the second opening 14. When the bottle body 1 includes a bottle body 101, a bottle cap 103, and a support base 102, the step 7 abuts against the inner wall of the bottle cap 103, which can prevent the pressing member 2 from falling off the sealing cavity 11 through the second opening 14.

[0063] Specifically, when the pressing member 2 includes a cover body 201 and a central column 202, the cover body 201 includes a first cylindrical body 2011 and a plate-shaped ring 2012, and the central column 202 includes a second cylindrical body 2021. The step 7 protrudes from the bottom end of the outer side wall of the first cylindrical body 2011. In this case, the plate-shaped ring 2012 can abut against the connection between the first cylindrical body 2011 and the step 7, and the plate-shaped ring 2012 and the first cylindrical body 2011 can directly abut without the need for connection, which can simplify the manufacturing process of the pressing member 2.

[0064] In the liquid storage container provided in this embodiment, a step 7 is convexly provided on the outer wall of the pressing member 2, and the step 7 will abut against the cavity wall of the sealing cavity 11 surrounding the outer periphery of the second opening 14, preventing the pressing member 2 from disengaging from the sealing cavity 11, improving the stability and safety of the liquid storage container, reducing the occurrence of accidental leakage or other accidents, and protecting the reliability of the storage container.

[0065] In some embodiments of the present utility model, please refer to Figure 4 , the liquid storage container further includes a breathable filter member 8, and the breathable filter member 8 is installed in the cover inner cavity 22, which can prevent dirt in the external air from entering the liquid storage cavity 12 through the breathable hole 21, the cover inner cavity 22, and the communication hole 23, ensuring the purity of the liquid in the liquid storage cavity 12.

[0066] In some embodiments of the present utility model, please refer to Figures 1 to 5 , the liquid storage container includes a bottle body 1, a pressing member 2, an elastic member 3, a limiting member 5, a sealing ring 4, and a pressing member 6.

[0067] The bottle body 1 comprises a bottle body 101, a support base 102 and a bottle cap 103. The bottle body 101 has an open mouth, the support base 102 is covered on the open mouth and encloses the bottle body 101 to form a liquid storage cavity 12; the middle part of the support base 102 is concave toward the liquid storage cavity 12, and the support base 102 is provided with a first opening 13; the bottle cap 103 is covered on the side of the support base 102 away from the bottle body 101 and encloses the support base 102 to form a sealed cavity 11, and the bottle cap 103 is provided with a second opening 14; the first opening 13 and the second opening 14 are both connected to the outside of the bottle body 1.

[0068] The outlet 15 may be provided with a pierceable plugging member, and the liquid in the liquid storage chamber 12 may be extracted after the plugging member is pierced. The outlet 15 may also be provided with a check structure to prevent residual liquid from flowing out when the container is replaced or taken out, thereby keeping the operating environment clean and improving the overall hygiene level of the container. The outlet 15 may also be provided with an easy-to-use quick connection device, such as a twist lock, a quick release device or an easy locking mechanism, which can quickly fix or release the liquid storage container, reducing the time and labor cost of replacement or installation, so that it is easy to quickly replace or install the container, and the user can easily perform maintenance, saving time and labor costs.

[0069] The pressing member 2 includes a first cylindrical body 2011, a plate-shaped ring 2012 and a second cylindrical body 2021 which enclose and form a cap inner cavity 22. The bottom of the first cylindrical body 2011 is open and a plurality of air holes 21 are provided on the top wall. The bottom end of the outer wall of the first cylindrical body 2011 is provided with a step 7 for abutting against the inner wall of the bottle cap 103, and the outer diameter of the step 7 is greater than the inner diameter of the second opening 14. The top of the second cylindrical body 2021 is open and a single connecting hole 23 is provided on the side wall. The outer diameter of the second cylindrical body 2021 is smaller than the outer diameter of the first cylindrical body 2011. The outer side of the plate-shaped ring 2012 abuts against the bottom end of the first cylindrical body 2011, and the inner side of the plate-shaped ring 2012 is connected to the top end of the second cylindrical body 2021. The first cylindrical body 2011 is movably sleeved in the second opening 14, and the second cylindrical body 2021 is movably sleeved in the first opening 13.

[0070] The limiting member 5 is protruded on the bottom wall of the support seat 102 , and the limiting member 5 is disposed around the first opening 13 . The limiting member 5 and the support seat 102 are integrally formed.

[0071] The sealing member is arranged between the limiting member 5 and the second cylindrical body 2021 .

[0072] The pressing member 6 is used to press the sealing member between the limiting member 5 and the second cylindrical body 2021 .

[0073] The elastic member 3 is sleeved on the outer sides of the limiting member 5 and the second cylindrical body 2021 , one end of the elastic member 3 abuts against the plate-shaped ring 2012 , and the other end of the elastic member 3 abuts against the inner wall of the support seat 102 .

[0074] In the liquid storage container adopted in this embodiment, when the pressing member 2 is not externally pressed, the sealing ring 4 is located on the side of the communication hole 23 close to the liquid storage cavity 12, and the elastic member 3 provides an elastic restoring force for the pressing member 2, so that the step 7 abuts against the inner wall of the bottle cap 103. The sealing ring 4 is located on the side of the communication hole 23 close to the liquid storage cavity 12, and the communication hole 23 and the liquid storage cavity 12 are isolated from each other, and the liquid storage cavity 12 remains in a sealed state. In this state, the liquid storage container can be stored and transported. When the pressing member 2 is externally pressed, that is, when the first cylindrical body 2011 is pressed, the first cylindrical body 2011 drives the second cylindrical body 2021 to compress the elastic member 3 until the communication hole 23 on the second cylindrical body 2021 and the liquid storage cavity 12 communicate with each other. At this time, the pressing member 2 is in an open state as a whole.
