Description

Technical Field

[0001] This application relates to the field of drinking water appliances, and more particularly to a liquid container. Background Technology

[0002] A liquid container consists of a lid and a body. The lid includes an inner lid mounted on the body and an outer lid that snaps onto the outside of the inner lid and can be used as a cup. The inner lid usually has a switch that needs to be opened and closed manually, which is inconvenient for users to use when pouring water. Utility Model Content

[0003] This application provides a liquid container that solves the problem in the prior art where users need to manually open and close the switch when pouring water from a liquid container, which is inconvenient to operate.

[0004] This application provides a liquid container, including a container body; the container lid includes an inner lid, an outer lid, and a sealing lid assembly, wherein the inner lid is detachably installed on the container body and has a water outlet channel communicating with the container body and the outside; the sealing lid assembly is movably installed on the inner lid and includes a sealing cover and an elastic element, wherein both ends of the elastic element abut against the sealing cover and the inner lid respectively; the outer lid is detachably connected to the container body, wherein when the outer lid is connected to the container body, the sealing cover closes the water outlet channel and compresses the elastic element under the drive of the outer lid; when the outer lid is disconnected from the container body, the sealing cover opens the water outlet channel under the drive of the elastic element.

[0005] In the above scheme, the sealing cap assembly is movably installed on the inner cap and is used to open or close the water outlet channel. When the outer cap is connected to the container body, the sealing cap is driven by the outer cap to approach the water outlet channel to close the water outlet channel. During this process, the sealing cap can compress the elastic element downward. When the outer cap is disconnected from the container body, the external force applied to the sealing cap disappears. At this time, the elastic element can return to its original shape, and the sealing cap can move away from the water outlet channel under the restoring force of the elastic element to open the water outlet channel.

[0006] In this embodiment, the outer cover and sealing cap assembly work together to automatically open the water outlet channel when the user removes the outer cover from the container body, and automatically close the water outlet channel when the user installs the outer cover back onto the container body. This eliminates the need for manual control of the water outlet channel's opening and closing, improving the convenience of pouring water from the liquid container and enhancing the user experience. Furthermore, the inner cover and container body are detachably connected, allowing the user to clean both the inner cover and the container body separately, further improving the convenience of cleaning the liquid container and enhancing the user experience.

[0007] In one possible design, the top of the sealing cap is provided with an abutment plane; during the connection between the outer cap and the container body, the inner top wall of the outer cap abuts against the abutment plane to drive the sealing cap to close the water outlet channel.

[0008] In the above solution, by setting an abutment plane on the top of the sealing cap, the driving engagement effect between the outer cap and the sealing cap can be achieved. Furthermore, the planar structure of the abutment plane increases the contact area between the outer cap and the sealing cap, which helps improve the reliability of the outer cap driving the sealing cap's movement. Moreover, when the abutment plane is set on the sealing cap to engage with the outer cap, there is no need to set a separate engagement structure on the inner top wall of the outer cap. This saves internal space in the outer cap, increases its capacity when used as a drinking cup, reduces hard-to-clean areas inside the outer cap, and makes it easier for users to clean the outer cap, thus improving the user experience.

[0009] In one possible design, the water outlet channel includes a water outlet disposed on the top of the inner cover; the sealing cover is provided with a first sealing ring, which is used to abut against the inner wall of the water outlet during the movement of the sealing cover relative to the inner cover to close the water outlet channel; the first sealing ring is also used to move away from the inner wall of the water outlet during the movement of the sealing cover relative to the inner cover to open the water outlet channel.

[0010] In the above scheme, when the outer cover is connected to the container body, the sealing cap, driven by the outer cover, moves the first sealing ring towards the outlet. When the first sealing ring abuts against the inner wall of the outlet, the outlet is closed, thus closing the water outlet channel. When the outer cover is disconnected from the container body, the sealing cap, driven by the elastic element, moves the first sealing ring away from the outlet. When the first sealing ring disengages from the inner wall of the outlet, the outlet is open, thus opening the water outlet channel.

[0011] In one possible design, the inner cover is provided with a mounting groove; the sealing cover is provided with a mounting post, at least a portion of which is located within the mounting groove and slidably connected to the mounting groove; the elastic element is located within the mounting groove along the axial direction of the container body, and both ends of the elastic element abut against the bottom wall of the mounting groove and the bottom wall of the mounting post, respectively.

[0012] In the above scheme, the mounting groove can position and guide the movement of the mounting post, which helps to improve the movement stability of the sealing cap. The elastic element is also set in the mounting groove, making the connection structure between the sealing cap assembly and the inner cover more compact. When the sealing cap moves downward under the drive of the outer cover, the bottom wall of the mounting post gradually approaches the bottom wall of the mounting groove to compress the elastic element. When the elastic element returns to its original shape, it can apply a force to the bottom wall of the mounting post to drive the bottom wall of the mounting post to gradually move away from the bottom wall of the mounting groove, thereby realizing the automatic reset of the sealing cap assembly.

[0013] In one possible design, the sealing cap assembly further includes a second sealing ring, which is fitted onto the side wall of the mounting post and seals against the inner side wall of the mounting groove.

[0014] In the above scheme, the second sealing ring is sealed to the inner wall of the mounting groove to prevent water in the water outlet channel from entering the mounting groove through the gap of the mounting column.

[0015] In one possible design, the liquid container further includes a limiting rod assembly, which includes a limiting rod and a limiting cap. One end of the limiting rod is mounted to the sealing cap, and the other end passes through the bottom wall of the inner cap. The limiting cap is mounted on the end of the limiting rod away from the sealing cap, and the limiting cap is used to limit the movement of the limiting rod relative to the inner cap by the sealing cap and engage with the bottom wall of the inner cap.

[0016] In the above solution, the cap can drive the limiting rod to move synchronously. When the sealing cap moves towards the inner bottom wall away from the inner cover, the limiting rod can drive the limiting cap to gradually approach the outer bottom wall of the inner cover. When the limiting cap abuts against the outer bottom wall of the inner cover to form a limiting fit, the inner cover can restrict the limiting rod assembly from continuing to move, thereby restricting the sealing cap from continuing to move away from the inner bottom wall of the inner cover, preventing the sealing cap from detaching from the inner cover. At the same time, it also limits the opening degree of the water outlet, avoiding excessive water flow when the liquid container is poured out, thus improving the user experience.

[0017] In one possible design, the outer wall of the limiting rod is provided with a sliding groove, the sliding groove including a first segment and a second segment that are connected to each other, the first segment extending along the axial direction of the limiting rod and the second segment extending along the circumferential direction of the limiting rod; the inner wall of the limiting cap is provided with a protrusion, during the rotation of the limiting cap relative to the limiting rod, the protrusion slides into the sliding groove so that when the protrusion slides to the second segment, it engages with the sliding groove, or when the protrusion slides to the first segment, it disengages from the sliding groove.

[0018] In the above solution, the protrusion can slide along the first segment to the connection between the first and second segments. Then, the limiting cap rotates relative to the limiting rod. When the protrusion slides into the second segment, it aligns with the second segment along the axial direction of the limiting rod. At this point, the protrusion engages with the slide groove, thus installing the limiting cap. When the limiting cap needs to be removed, it rotates in the opposite direction relative to the limiting rod, allowing the protrusion to slide along the second segment to the first segment. Then, the protrusion continues to slide along the first segment until it disengages from the slide groove, releasing the engagement and thus removing the limiting cap. By rotating the limiting cap relative to the limiting rod to achieve engagement and unlocking of the protrusion and slide groove, the connection structure between the limiting rod and the limiting cap is simplified, the operational difficulty of the connection process is reduced, and the user experience is improved.

[0019] In one possible design, the bottom wall of the inner cover is provided with a mounting hole, and the limiting rod passes through the mounting hole; the limiting rod assembly also includes a third sealing ring, which is sleeved on the side wall of the limiting rod and is in sealing fit with the inner wall of the mounting hole.

[0020] In the above scheme, the third sealing ring is sealed to the inner wall of the mounting hole to prevent water inside the container from entering the mounting groove through the gap between the mounting hole and the limiting rod.

[0021] In one possible design, the inner cover is detachably connected to the inner wall of the container body; the outer cover is detachably connected to the outer wall of the container body.

[0022] In the above scheme, the structure for connecting with the inner cover and the structure for connecting with the outer cover on the container body are set separately, which can avoid the inner cover from obstructing the connection with the outer cover.

[0023] In one possible design, the container lid further includes a fourth sealing ring, which is fitted onto the side wall of the inner lid and forms a sealing fit with the inner side wall of the container body.

[0024] In the above solution, the fourth sealing ring is sealed to the inner wall of the container to prevent liquid in the container from leaking out from the gap between the inner cap and the container, reducing the risk of leakage when the liquid container is poured, and improving the user experience.

[0025] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0070] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0071] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0072] This application provides a liquid container, such as... Figure 1 As shown, the liquid container includes a container body 10 and a container lid 20. The container body 10 is used to store liquid, and the container lid 20 is fastened to the container body 10, serving to seal and prevent dust from entering the liquid inside the container body 10. Figure 2 and Figure 3 As shown, the container lid 20 includes an inner lid 1, an outer lid 2, and a sealing lid assembly 3. The inner lid 1 is detachably installed on the container body 10 and has a water outlet channel 11, which communicates with both the container body 10 and the outside. The sealing lid assembly 3 is movably installed on the inner lid 1 and is used to open or close the water outlet channel 11. The sealing lid assembly 3 includes a sealing cover 31 and an elastic element 32, with both ends of the elastic element 32 abutting against the sealing cover 31 and the inner lid 1, respectively. The outer lid 2 is detachably connected to the container body 10 and is fastened to the outside of the inner lid 1. When the outer lid 2 is connected to the container body 10, the sealing cover 31 is driven by the outer lid 2 to approach the water outlet channel 11 to close the water outlet channel 11. During this process, the sealing cover 31 can compress the elastic element 32 downwards; Figure 4 and Figure 5 As shown, when the outer cover 2 is disconnected from the container body 10, the external force applied to the sealing cover 31 disappears. At this time, the elastic element 32 can return to its original shape, and the sealing cover 31 can move away from the water outlet channel 11 under the driving force of the elastic element 32, so as to open the water outlet channel 11. The water in the container body 10 can be poured out through the water outlet channel 11. At this time, the outer cover 2 can be used as a drinking cup for the user to drink water.

[0073] In this embodiment, the outer cover 2 cooperates with the sealing cover assembly 3. When the user removes the outer cover 2 from the container body 10, the water outlet channel 11 automatically opens. When the user installs the outer cover 2 back onto the container body 10, the water outlet channel 11 automatically closes. This eliminates the need for manual control of the opening and closing of the water outlet channel 11, improving the convenience for users when pouring water from the liquid container and enhancing the user experience. Furthermore, in this embodiment, the inner cover 1 and the container body 10 are detachably connected, allowing users to clean both the inner cover 1 and the container body 10 separately, further improving the convenience of cleaning the liquid container and enhancing the user experience.

[0074] In one specific implementation, such as Figure 3 As shown, the top of the sealing cover 31 is provided with an abutting surface 311. During the process of connecting the outer cover 2 with the container body 10, the inner top wall of the outer cover 2 abuts against the abutting surface 311 so that the outer cover 2 can drive the sealing cover 31 to move synchronously, thereby closing the water outlet channel 11.

[0075] In this embodiment, by providing an abutment plane 311 on the top of the sealing cap 31, the driving engagement effect between the outer cap 2 and the sealing cap 31 can be achieved. Furthermore, the planar structure of the abutment plane 311 increases the contact area between the outer cap 2 and the sealing cap 31, which is beneficial for improving the reliability of the outer cap 2 driving the sealing cap 31 to move. Moreover, when the abutment plane 311 is provided on the sealing cap 31 to engage with the outer cap 2, there is no need to provide a separate engagement structure on the inner top wall of the outer cap 2. This helps save internal space in the outer cap 2, increases its capacity when used as a drinking cup, and reduces hard-to-clean areas inside the outer cap 2, making it easier for users to clean the outer cap 2 and improving the user experience.

[0076] In one specific implementation, such as Figure 3 As shown, the water outlet channel 11 includes a water outlet 111 disposed on the top of the inner cover 1 and a water passage hole 112 disposed on the bottom wall of the inner cover 1. The water passage hole 112 is used to communicate with the interior of the container body 10, and the water outlet 111 is used to communicate with the outside. In this embodiment, the sealing cover 31 opens and closes the water outlet channel 11 by opening and closing the water outlet 111.

[0077] Specifically, the sealing cap 31 includes a cap body 310 and a first sealing ring 33 fitted onto the cap body 310, with an abutment plane 311 disposed on the cap body 310. The first sealing ring 33 is used to abut against the inner wall of the outlet 111 during the movement of the sealing cap 31 relative to the inner cap 1, thereby closing the water outlet channel 11. The first sealing ring 33 is also used to move away from the inner wall of the outlet 111 during the movement of the sealing cap 31 relative to the inner cap 1, thereby opening the water outlet channel 11.

[0078] In this embodiment, such as Figure 3 As shown, when the outer cover 2 is connected to the container body 10, the cover body 310 can drive the first sealing ring 33 to move in the direction close to the water outlet 111 under the drive of the outer cover 2. When the first sealing ring 33 abuts against the inner wall of the water outlet 111, the water outlet 111 is in a closed state, thereby closing the water outlet channel 11. Figure 5 As shown, when the outer cover 2 is disconnected from the container body 10, the cover body 310 can drive the first sealing ring 33 to move away from the water outlet 111 under the drive of the elastic element 32. When the first sealing ring 33 is released from the contact with the inner wall of the water outlet 111, the water outlet 111 is in the open state, so as to realize the opening of the water outlet channel 11.

[0079] Among them, such as Figure 6 As shown, a first mounting groove 310a for installing the first sealing ring 33 can be provided on the side wall of the cover body 310, which is beneficial to improving the installation stability of the first sealing ring 33.

[0080] In this embodiment, the elastic element 32 can be a spring, a sheet, or other compressible elastic component, and this application does not limit this. The specific structure of the sealing cover assembly 3 and the inner cover 1 will be described below using the example of the elastic element 32 being a spring.

[0081] In one specific implementation, such as Figure 3 As shown, the inner cover 1 has an installation groove 12 inside, which can be formed on the inner bottom wall of the inner cover 1. Multiple water passage holes 112 are arranged around the installation groove 12. The sealing cover 31 also has an installation post 312 fixedly connected to the cover body 310. At least a portion of the installation post 312 is located within the installation groove 12 and slidably connected to it. The installation groove 12 can position and guide the movement of the installation post 312, which helps improve the movement stability of the sealing cover 31. An elastic element 32 is also provided within the installation groove 12, making the connection structure between the sealing cover assembly 3 and the inner cover 1 more compact. Along the axial direction Z of the container body 10, both ends of the elastic element 32 abut against the inner bottom wall of the installation groove 12 and the outer bottom wall of the installation post 312, respectively. When the sealing cover 31 moves downward under the drive of the outer cover 2, the bottom wall of the installation post 312 gradually approaches the bottom wall of the installation groove 12 to compress the elastic element 32. Figure 5 As shown, when the elastic element 32 returns to its original state, it can apply a force to the bottom wall of the mounting post 312 to drive the bottom wall of the mounting post 312 to gradually move away from the bottom wall of the mounting groove 12, so as to realize the automatic reset of the sealing cover assembly 3.

[0082] Specifically, such as Figure 5As shown, a columnar elastic element mounting part 121 can be provided in the mounting groove 12. The elastic element 32 is sleeved on the outer wall of the elastic element mounting part 121, which can reduce the risk of the elastic element 32 shaking or shifting, and is conducive to improving the installation stability and movement stability of the elastic element 32.

[0083] In this embodiment, the sealing cap assembly 3 further includes a second sealing ring 34, which is sleeved on the side wall of the mounting post 312 and seals against the inner side wall of the mounting groove 12 to prevent water in the water outlet channel 11 from entering the mounting groove 12 through the gap in the mounting post 312.

[0084] Specifically, such as Figure 6 As shown, a second mounting groove 312a for mounting the second sealing ring 34 can be provided on the side wall of the mounting post 312, which helps to improve the installation stability of the second sealing ring 34. The second sealing ring 34 can be provided with raised sealing ribs, which are used to make an interference fit with the inner side wall of the mounting groove 12 to improve the sealing effect of the second sealing ring 34.

[0085] In one specific implementation, such as Figure 3 As shown, the liquid container also includes a limiting rod assembly 4, which includes a limiting rod 41 and a limiting cap 42. One end of the limiting rod 41 is installed on the sealing cap 31, and the other end passes through the mounting hole 13 on the bottom wall of the inner cover 1. The limiting cap 42 is installed at the end of the limiting rod 41 away from the sealing cap 31, that is, the limiting cap 42 is located on the outer bottom wall side of the inner cover 1. The limiting cap 42 is used to limit the movement of the limiting rod 41 relative to the inner cover 1 by the sealing cap 31.

[0086] In this embodiment, the sealing cover 31 can drive the limiting rod 41 to move synchronously. When the sealing cover 31 moves away from the inner bottom wall of the inner cover 1, the limiting rod 41 can drive the limiting cap 42 to gradually approach the outer bottom wall of the inner cover 1. Figure 5 As shown, when the limiting cap 42 abuts against the outer bottom wall of the inner cover 1 to form a limiting fit, the inner cover 1 can restrict the limiting rod assembly 4 from continuing to move, thereby restricting the sealing cover 31 from continuing to move away from the inner bottom wall of the inner cover 1, preventing the sealing cover 31 from detaching from the inner cover 1. At the same time, it also restricts the opening degree of the water outlet 111, avoiding excessive water flow when the liquid container is poured out, thus improving the user experience.

[0087] Specifically, such as Figure 3 As shown, the end of the limiting rod 41 connected to the sealing cover 31 can be specifically installed on the mounting post 312. The limiting rod 41 is provided with a protruding end 412, which is located inside the mounting post 312 to improve the connection reliability between the limiting rod 41 and the mounting post 312 and prevent the limiting rod 41 from detaching from the mounting post 312.

[0088] The mounting hole 13 on the inner cover 1 can be specifically set in the elastic element mounting part 121, which helps to save the internal space of the inner cover 1 and improve the compactness of the connection structure between the sealing cover assembly 3 and the inner cover 1.

[0089] In one specific embodiment, the limiting cap 42 and the limiting rod 41 are detachably connected, such as... Figure 6 and Figure 7 As shown, the outer wall of the limiting rod 41 is provided with a sliding groove 411, which includes a first section 411a and a second section 411b that are connected. The first section 411a extends along the axial direction Z of the limiting rod 41, and the second section 411b extends along the circumferential direction of the limiting rod 41. The inner wall of the limiting cap 42 is provided with a protrusion 421. During the rotation of the limiting cap 42 relative to the limiting rod 41, the protrusion 421 slides and engages with the sliding groove 411, so that when the protrusion 421 slides to the second section 411b, it engages with the sliding groove 411, or when the protrusion 421 slides to the first section 411a, it disengages from the sliding groove 411.

[0090] In this embodiment, the protrusion 421 can slide along the first segment 411a to the connection between the first segment 411a and the second segment 411b. Then, the limiting cap 42 rotates relative to the limiting rod 41. When the protrusion 421 slides into the second segment 411b, the protrusion 421 and the second segment 411b are aligned along the axial direction Z of the limiting rod 41. At this time, the protrusion 421 and the slide groove 411 form a locking engagement, thereby realizing the installation of the limiting cap 42. When it is necessary to remove the limiting cap 42, the limiting cap 42 is rotated in the opposite direction relative to the limiting rod 41. The protrusion 421 can slide along the second segment 411b to the first segment 411a. At this time, the protrusion 421 can continue to slide along the first segment 411a until it disengages from the slide groove 411, thereby releasing the locking engagement with the slide groove 411 and realizing the removal of the limiting cap 42. The engagement and unlocking of the protrusion 421 and the slide groove 411 are achieved by rotating the limit cap 42 relative to the limit rod 41. This not only simplifies the connection structure between the limit rod 41 and the limit cap 42, but also reduces the operational difficulty of the connection process and improves the user experience.

[0091] In this embodiment, such as Figure 3 As shown, the limiting rod assembly 4 also includes a third sealing ring 43, which is sleeved on the side wall of the limiting rod 41. The third sealing ring 43 is sealed to the inner wall of the mounting hole 13 to prevent water in the container body 10 from entering the mounting groove 12 through the gap between the mounting hole 13 and the limiting rod 41.

[0092] Specifically, such as Figure 6As shown, a third mounting groove 413 for installing the third sealing ring 43 can be provided on the side wall of the limiting rod 41, which helps to improve the installation stability of the third sealing ring 43. The third sealing ring 43 can be provided with raised sealing ribs, which are used to make an interference fit with the inner side wall of the mounting hole 13 to improve the sealing effect of the third sealing ring 43.

[0093] In one specific embodiment, the inner cover 1 is detachably connected to the inner wall of the container body 10, and the outer cover 2 is detachably connected to the outer wall of the container body 10. That is, the structure on the container body 10 for connecting with the inner cover 1 and the structure for connecting with the outer cover 2 are set separately, which can avoid the inner cover 1 from obstructing the connection with the outer cover 2.

[0094] The inner cover 1 and the container body 10 can be detachably connected by means of threaded connection, snap-fit ​​connection, magnetic connection, etc., and this application embodiment does not limit this. The outer cover 2 and the container body 10 can be detachably connected by means of threaded connection, snap-fit ​​connection, magnetic connection, etc., and this application embodiment does not limit this.

[0095] In one specific implementation, such as Figure 2 As shown, the container lid 20 also includes a fourth sealing ring 5, which is fitted onto the side wall of the inner lid 1. The fourth sealing ring 5 is sealed to the inner side wall of the container body 10 to prevent liquid in the container body 10 from leaking out from the gap between the inner lid 1 and the container body 10, thereby reducing the risk of leakage when the liquid container is poured and improving the user experience.

[0096] Specifically, such as Figure 6 As shown, a fourth mounting groove 14 for installing the fourth sealing ring 5 can be provided on the side wall of the inner cover 1, which helps to improve the installation stability of the fourth sealing ring 5.
