[0001] The utility model relates to the field of containers, and particularly to a cup cover assembly and a water cup. Background Art

[0002] At present, the cup cover assembly of the water cup on the market includes an outer cover and an inner plug located inside the outer cover. A sealing ring is sleeved on the inner plug to seal the top opening of the cup body. The inner plug and the outer cover are usually fixed together, but this will make it difficult to clean the position between the inner plug and the outer cover, and it is easy to produce peculiar smell after long-term use. Summary of the Utility Model

[0003] Therefore, the purpose of the utility model is to provide a cup cover assembly and a water cup to solve at least one of the problems existing in the above-mentioned prior art or related art.

[0004] The first aspect embodiment of the utility model provides a cup cover assembly, which includes: an outer cover, with a first engaging part on the inner side; an inner plug assembly, detachably arranged in the outer cover. The inner plug assembly includes an inner plug and a first engaging member. A hollow inner plug cavity is formed in the inner plug. The first engaging member is movably arranged in the inner plug cavity. The first engaging member can be engaged with the first engaging part to fix the inner plug to the outer cover, or the first engaging member can also be disengaged from the first engaging part to detach the inner plug from the outer cover.

[0005] The cup cover assembly provided by the embodiment of this aspect makes the inner plug assembly detachably connected to the outer cover, and realizes the assembly and disassembly of the two through the mutual cooperation of the first engaging member and the first engaging part. The disassembly and assembly are convenient, so that it is convenient to clean the outer cover and the inner plug assembly separately, and the cleaning effect is good. Moreover, the first engaging member is arranged inside the inner plug, and the main structure of the first engaging member is located in the inner plug cavity, which is not easy to contact the water vapor or impurities in the cup body, and can prevent a large amount of water vapor or impurities from adhering to the first engaging member and causing pollution. Moreover, when the cup cover assembly is opened and the cup cover assembly is observed from the bottom of the cup cover assembly, the main structure of the first engaging member is hidden in the inner plug and will not be exposed, and the visual effect is good.

[0006] In some embodiments, one of the first engaging part and the first engaging member is provided with a slot, and the other includes a hook part that cooperates with the slot. The structure is simple and convenient for processing.

[0007] In some embodiments, the inner plug assembly further includes: a sealing member, detachably arranged on the inner plug, for fitting with the inner wall of the cup body. The sealing member can push the first engaging member to move so that the first engaging member is engaged with the first engaging part.

[0008] In these embodiments, when disassembling the inner plug assembly, first disassemble the seal to relieve the extrusion of the seal on the first engaging member, so as to cause the first engaging member to move away from the first engaging portion. When installing the inner plug assembly, the seal needs to be installed first, and the elastic force of the seal itself is used to squeeze the first engaging member, thereby pushing the first engaging member to be engaged with the first engaging portion. Compared with additionally providing a button to apply a thrust force to the first engaging member, the number of components can be reduced and the cost can be saved. Moreover, the elastic force of the seal can keep the first engaging member and the first engaging portion in an engaged connection, which is beneficial to improving the connection stability between the inner plug assembly and the outer cover. When the seal is not installed, the first engaging member cannot be easily engaged with the first engaging portion, and the omission of the seal can also be avoided.

[0009] In some embodiments, the inner plug assembly further includes: an elastic member disposed inside the inner plug cavity and located between the cavity wall of the inner plug cavity and the first engaging member. In the case where the seal is separated from the inner plug, the first engaging member can be separated from the first engaging portion under the elastic force of the elastic member.

[0010] In these embodiments, after the seal is disassembled, the first engaging member can automatically and quickly move away from the first engaging portion under the elastic force of the elastic member, which is convenient for the quick disassembly of the inner plug assembly. Moreover, by disposing the elastic member in the inner plug cavity, shielded by the inner plug, it is not easy for water vapor or impurities to adhere to the elastic member, and it is not easy to be contaminated or deteriorated, which is convenient for quick and thorough cleaning. In addition, the elastic member does not occupy the gap between the inner plug and the outer cover and does not interfere with the top of the cup body inserted into the outer cover.

[0011] In some embodiments, the inner plug includes an inner plug side wall and an inner plug bottom wall connected to the inner plug side wall. An avoidance opening is provided on the inner plug side wall, the seal is an O-ring, and the O-ring can block the avoidance opening and push the first engaging member to move through the avoidance opening.

[0012] In these embodiments, by providing an avoidance opening on the inner plug side wall, after the O-ring is tightly sleeved on the inner plug, the O-ring has a tendency to shrink, and it is easier to apply an extrusion force to the avoidance opening towards the first engaging member, thereby pushing the first engaging member to be separated from the first engaging portion. Moreover, the O-ring can block the avoidance opening, preventing the avoidance opening from being exposed, thereby improving the appearance effect. Moreover, when the cup lid assembly is closed on the cup body, water vapor or impurities can be prevented from entering the inner plug cavity through the avoidance opening, preventing the components inside the inner plug cavity from being contaminated.

[0013] In some embodiments, the first engaging member is swingably connected to the inner plug side wall of the inner plug, or the first engaging member can move horizontally on the inner plug bottom wall of the inner plug. Here, the first engaging member is caused to move along a set path, which is convenient for the first engaging member to align with the first engaging portion and be engaged therewith.

[0014] In some embodiments, the outer cover includes an outer cover top wall and an outer cover side wall, and the first engaging portion is disposed on the inner surface of the outer cover side wall. A part of the first engaging member extends outward relative to the inner plug side wall of the inner plug to be engaged with the first engaging portion. Here, the first engaging portion is directly disposed on the outer cover side wall, so the outer cover has a simple structure and is convenient to process.

[0015] In some embodiments, the first engaging portion is disposed at a position on the outer cover side wall higher than the inner plug side wall. The inner plug has a top opening and is communicated with the inner plug cavity. A part of the first engaging member extends out of the inner plug cavity through the top opening of the inner plug and extends toward the first engaging portion.

[0016] In these embodiments, the portion of the first engaging member that cooperates with the first engaging portion is higher than the inner plug. Then, when the cup lid assembly is covered on the cup body and the top of the cup body is inserted into the gap between the outer cover and the inner plug, the top of the cup body will not interfere with the first engaging member, and the two do not affect each other. Moreover, compared with providing an opening on the inner plug side wall for the first engaging member to extend out, it will not affect the main structure of the inner plug, which is beneficial to ensuring the structural strength of the inner plug.

[0017] In some embodiments, a positioning rib protruding radially is provided on the outer surface of the inner plug, and a step is further provided on the inner surface of the outer cover side wall of the outer cover. The upper surface of the positioning rib abuts against the lower surface of the step.

[0018] In these embodiments, when the cup lid assembly is covered on the top of the cup body, the cup lid will be pressed down. When the inner plug assembly includes a sealing member that fits tightly with the cup body, a reaction force will be generated after the sealing member is pressed and acts on the inner plug. Here, the positioning rib is designed to abut and cooperate with the step surface on the inner side of the outer cover, which can effectively prevent the inner plug from moving upward and improve the installation stability of the inner plug.

[0019] In addition, the design of the positioning rib and the step can also achieve a sealing effect, which can block the water vapor or impurities between the outer cover and the inner plug from flowing upward continuously, so that the part of the outer cover and the inner plug above the step, as well as the inside of the inner plug, are not attached or less attached with impurities, thus facilitating quick and thorough cleaning.

[0020] In some embodiments, a second engaging portion is disposed at a position in the outer cover opposite to the first engaging portion, and a second engaging member is disposed on a side of the inner plug opposite to the first engaging member. The second engaging member can be engaged with the second engaging portion, and the second engaging member and the inner plug are integrally formed.

[0021] In these embodiments, the inner plug and the outer cover are connected by the first engaging member and the second engaging member distributed relatively, and the connection stability is good. Moreover, the second engaging member and the inner plug are of an integral structure, and the connection is firm, which is beneficial to the stable connection of the inner plug to the outer cover.

[0022] In a second aspect embodiment of the present utility model, a water cup is provided. The water cup includes a cup body and a cup cover assembly as described in any one of the above embodiments. The cup cover assembly is detachably covered at the top opening of the cup body.

[0023] Since the water cup provided in the embodiment of this aspect has the cup cover assembly of any one of the above embodiments, it thus has the beneficial effects of any one of the above embodiments, which will not be elaborated here.

[0024] Some other aspects and / or advantages of the general concept of the present utility model will be described in part in the following description, some will be clear from the description, or can be learned through the implementation of the general concept of the present utility model.

[0045] Next, the cup lid assembly and water cup provided by the embodiments of the present utility model will be introduced in conjunction with Figures 1 to 4 the cup lid assembly and water cup provided by the embodiments of the present utility model will be introduced.

[0046] As Figures 1 to 4 shown, an embodiment of the first aspect of the present utility model provides a cup lid assembly, and the cup lid assembly includes an outer lid 10 and an inner plug assembly.

[0047] The outer lid 10 includes an outer lid top wall 110 and an outer lid side wall 120, and the two can be a split structure or integrally formed.

[0048] The inner plug assembly is detachably disposed within the outer lid 10. This facilitates the disassembly of the inner plug assembly and the separate cleaning of the inner plug assembly and the outer lid 10, with convenient cleaning and good cleaning effect.

[0049] As Figure 1 and Figure 2 shown, the inner plug assembly includes an inner plug 20 and a first engaging member 30. A hollow inner plug cavity 230 is formed in the inner plug 20, and the first engaging member 30 is movably disposed within the inner plug cavity 230. The inner side of the outer lid 10 has a first engaging portion 121. The first engaging member 30 can be engaged with the first engaging portion 121 to fix the inner plug assembly to the outer lid 10, and the first engaging member 30 can also be disengaged from the first engaging portion 121 to enable the inner plug 20 to be detached from the outer lid 10.

[0050] Here, the assembly and disassembly of the inner plug assembly and the outer cover 10 are realized through the mutual cooperation of the first engaging member 30 and the first engaging portion 121. The disassembly and assembly are convenient, so that it is convenient to clean the outer cover 10 and the inner plug assembly separately, and the cleaning effect is good. Moreover, the first engaging member 30 is arranged inside the inner plug 20, and the main structure of the first engaging member 30 is located in the inner plug cavity 230, and it is not easy to contact the water vapor or impurities in the cup body 60, which can prevent a large amount of water vapor or impurities from adhering to the first engaging member 30 and causing pollution. Moreover, when the cup cover assembly is opened and the cup cover assembly is observed from the bottom of the cup cover assembly, the main structure of the first engaging member 30 is hidden in the inner plug 20 and will not be exposed, and the visual effect is good.

[0051] One of the first engaging portion 121 and the first engaging member 30 is provided with a card slot, and the other includes a hook portion that cooperates with the card slot. The structure is simple and convenient for processing.

[0052] Figure 1 and Figure 4 The scheme in which the card slot is provided at the first engaging portion 121 on the outer cover 10 and the first engaging member 30 is a hook is shown. Therefore, the following will be combined with the attached Figures 1 to 4 , and the case where the first engaging portion 121 has a card slot and the first engaging member 30 is a hook will be taken as an example for detailed description. In this case, the first engaging member 30 may include a hook portion 310, and the hook portion 310 is inserted into the card slot. The first engaging member 30 may further include a pressing portion 320. By applying a force to the pressing portion 320, the hook portion 310 of the first engaging member 30 is pushed into the card slot.

[0053] Regarding how to trigger the movement of the first engaging member 30, further, in some embodiments, as Figure 1 and 2 shown, the inner plug assembly further includes a sealing member 50. The sealing member 50 is detachably arranged on the inner plug 20 and is used to fit with the inner wall of the cup body 60. The sealing member 50 can also push the first engaging member 30 to move, so that the first engaging member 30 is engaged with the first engaging portion 121.

[0054] Here, in addition to being used to fit with the inner wall of the cup body 60, the sealing member 50 is also used to trigger the hook portion 310 of the first engaging member 30 to be inserted into the first engaging portion 121. Compared with additionally providing a button to apply a thrust to the pressing portion 320, the number of components can be reduced and the cost can be saved. Moreover, the elastic force of the sealing member 50 can keep the hook portion 310 in the first engaging portion 121, which is beneficial to improving the connection stability between the inner plug assembly and the outer cover 10. When the sealing member 50 is not installed, the hook portion 310 of the first engaging member 30 cannot be easily inserted into the first engaging portion 121, and the omission of the sealing member 50 can also be avoided.

[0055] Specifically, when disassembling the inner plug assembly, the seal 50 is first disassembled to release the seal 50 from squeezing the squeezing portion 320 of the first clamping member 30, so as to cause the hook portion 310 to be separated from the first clamping portion 121. When installing the inner plug assembly, the seal 50 is first installed, and the elastic force of the seal 50 itself is used to apply squeezing force to the squeezing portion 320, so as to push the hook portion 310 to be clamped into the first clamping portion 121, which is convenient for disassembly and assembly.

[0056] As an example, the sealing member 50 is a sealing ring, which facilitates circumferential sealing with the cup body 60 and can be securely mounted on the inner plug 20 .

[0057] In order to facilitate the first clamping component 30 to automatically move away from the first clamping portion 121 after the sealing component 50 is removed, further, in some embodiments, the first clamping component 30 can be swingably set on the inner plug side wall 210 of the inner plug 20, and a counterweight block can be set on the first clamping component 30, and the weight of the counterweight block can be used to make the first clamping component 30 swing back to its original position and away from the first clamping portion 121.

[0058] In other embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the cup cover assembly can also include an elastic member 40, which is arranged inside the inner plug cavity 230 and between the cavity wall of the inner plug cavity 230 and the first clamping member 30. When the sealing ring is separated from the inner plug 20, the first clamping member 30 can be separated from the first clamping portion 121 under the elastic force of the elastic member 40.

[0059] Here, the elastic force of the elastic member 40 is used to push the first clamping member 30 to separate from the first clamping portion 121, which is conducive to the first clamping member 30 to quickly move away from the first clamping portion 121, and facilitates the rapid disassembly of the inner plug assembly. In addition, the elastic member 40 is arranged in the inner plug cavity 230, and is shielded by the inner plug 20. It is not easy for water vapor or impurities to adhere to the elastic member 40, and it is not easy to be polluted or deteriorated, which is convenient and quick to clean. In addition, the elastic member 40 will not occupy the gap between the inner plug 20 and the outer cover 10, and will not interfere with the top of the cup body 60 inserted into the outer cover 10.

[0060] Of course, during the installation of the inner plug 20 , after the seal 50 is sleeved on the inner plug 20 , the elastic force of the seal 50 needs to overcome the elastic force of the elastic member 40 to push the hook portion 310 of the first clamping member 30 into the first clamping portion 121 .

[0061] Furthermore, in some embodiments, Figure 1 combine Figure 2As shown, the inner plug 20 includes an inner plug side wall 210 and an inner plug bottom wall 220 connected to the inner plug side wall 210. An avoidance opening 211 is provided on the inner plug side wall 210, and the extrusion part 320 is exposed through the avoidance opening 211. The sealing member 50 extrudes the extrusion part 320 through the avoidance opening 211 to push the first engaging member 30 to move. After the sealing member 50 is removed, the setting of the avoidance opening 211 enables the first engaging member 30 to have a space to swing around the inner plug side wall 210, so that the first engaging member 30 can disengage from the first engaging portion 121.

[0062] Among them, an avoidance opening 211 is provided on the inner plug side wall 210. After the sealing member 50 is tightly sleeved on the inner plug 20, the sealing member 50 has a tendency to shrink, and it is easier to apply an extrusion force to the extrusion part 320 at the avoidance opening 211, thereby pushing the first engaging member 30 to be engaged with the first engaging portion 121.

[0063] To further avoid the pollution of the internal components of the inner plug 20, in some embodiments, the sealing member 50 can block the avoidance opening 211. On the one hand, it avoids the exposure of the avoidance opening 211, thereby improving the appearance effect. On the other hand, when the cup lid assembly is closed on the cup body 60, water vapor or impurities can be prevented from entering the inner plug cavity 230 through the avoidance opening 211, preventing the pollution of the internal components in the inner plug cavity 230.

[0064] Regarding the setting position of the first engaging portion 121, further, in some embodiments, as Figure 1 and Figure 2 shown, the first engaging portion 121 is provided on the inner surface of the outer cover side wall 120. The structure of the outer cover 10 is simple and convenient to process. At this time, a part of the first engaging member 30 extends outward relative to the inner plug side wall 210 to be engaged with the first engaging portion 121.

[0065] As an example, referring to Figure 1 and Figure 2 , the inner plug cavity 230 can have a top opening. For example, the inner plug side wall 210 and the inner plug bottom wall 220 enclose an inner plug cavity 230 with an opening at the top, or the inner plug 20 further includes an inner plug top wall with an opening provided thereon. The hook portion 310 extends out of the inner plug cavity 230 through the top opening of the inner plug cavity 230 and extends laterally, and the first engaging portion 121 is provided at a position on the outer cover side wall 120 higher than the inner plug side wall 210.

[0066] Since the position of the hook portion 310 is higher than that of the inner plug 20, during the process of the cup lid assembly being closed on the cup body 60 and the top of the cup body 60 being inserted into the gap between the outer cover 10 and the inner plug 20, the top of the cup body 60 will not interfere with the hook portion 310, and the two do not affect each other. Moreover, compared with providing an opening on the inner plug side wall 210 for the hook portion 310 to extend out, it does not affect the main structure of the inner plug 20, which is beneficial to ensuring the structural strength of the inner plug 20.

[0067] As an example, an opening may also be provided on the inner plug side wall 210 for the hook portion 310 to protrude. For example, a notch is provided at the top of the inner plug side wall 210 for the hook portion 310 to protrude. At this time, the hook portion 310 may be lower than the top of the inner plug side wall 210, and the position of the hook portion 310 can be set as needed.

[0068] Further, in some other embodiments, the inner plug 20 has a top opening that communicates with the inner plug cavity 230. The outer cover 10 includes an outer cover top wall 110 and an outer cover side wall 120. The lower surface of the outer cover top wall 110 has a hanging rib (not shown in the figure) protruding toward the inner plug cavity 230, and the first engaging portion 121 is provided on the hanging rib.

[0069] Here, the first engaging portion 121 is provided on the hanging rib extending downward from the outer cover top wall 110, eliminating the need to provide a card slot on the outer cover side wall 120, which is beneficial to ensuring the structural strength of the outer cover 10. Moreover, by making the hanging rib protrude toward the inner plug cavity 230 and its projection on the horizontal plane fall into the inner plug cavity 230, the hook portion 310 of the first engaging member 30 does not need to protrude laterally out of the inner plug cavity 230 to connect with the first engaging portion 121 on the outer cover side wall 120. Moisture or impurities will not directly impact the hook portion 310, and the probability of moisture and impurities adhering to the hook portion 310 can be reduced. Moreover, when the cup lid assembly is opened and the cup lid assembly is observed from the bottom of the cup lid assembly, the first engaging member 30 is entirely hidden inside the inner plug 20, and the appearance effect is good.

[0070] In this case, the hanging rib can be located above the inner plug cavity 230, and the first engaging portion 121 can be located above the inner plug cavity 230. Then, the hook portion 310 protrudes upward out of the inner plug cavity 230 and then extends laterally to insert into the first engaging portion 121. It is also possible to make the hanging rib extend into the top opening of the inner plug 20, and the first engaging portion 121 is located at the inner top of the inner plug cavity 230. At this time, the hook portion 310 inserts into the first engaging portion 121 inside the inner plug cavity 230.

[0071] Regarding the movement path of the first engaging member 30, further, in some embodiments, as Figure 1 and Figure 2 shown, the first engaging member 30 is swingably connected to the inner plug side wall 210, or the first engaging member 30 can move horizontally on the inner plug bottom wall 220. Here, making the first engaging member 30 move along a set path facilitates the first engaging member 30 to align with the first engaging portion 121 and engage with it.

[0072] In a specific embodiment, as Figure 1 、 Figure 2 and Figure 4As shown, the first clamping member 30 is swingably connected to the inner side wall 210 of the inner plug. On both sides in the width direction of the first clamping member 30, there are integrally connected convex columns, and the convex columns are configured as connecting shafts 330. On the inner surface of the inner side wall 210 of the inner plug, there are two connecting ribs 212 distributed at intervals. On the two connecting ribs 212, there are shaft holes 213 arranged face to face. The two convex columns are respectively inserted into the shaft holes 213 and can rotate within the shaft holes 213. When installing the first clamping member 30, the first clamping member 30 can be squeezed between the two connecting ribs 212, and the two convex columns are inserted into the corresponding shaft holes 213. The installation of the first clamping member 30 is convenient and it is not easy to fall off. Moreover, compared with the related art in which an additional rotating shaft penetrates through the first clamping member 30 and the two connecting ribs 212, and the first clamping member 30 rotates around the center line of the rotating shaft, the number of parts can be reduced and the cost can be saved.

[0073] On one side of the first clamping member 30 facing the inner side wall 210 and / or on the inner surface of the inner side wall 210 of the inner plug, there is a groove 340. The elastic member 40 is a spring, and the end of the spring is inserted into the corresponding groove 340. The design of the groove 340 can, on the one hand, limit the spring, and on the other hand, the groove 340 does not occupy the space between the first clamping member 30 and the inner side wall 210, facilitating the rotation of the first clamping member 30 towards the inner side wall 210 without being interfered by the groove 340.

[0074] The elastic member 40 is a spring, and one end of the spring abuts on a part of the first clamping member 30 above its rotation center line. The spring is close to the hook portion 310, facilitating the elastic member 40 to apply a relatively small force to push the hook portion 310 away from the first engaging portion 121, so that it is convenient for the sealing ring to overcome the elastic force of the elastic member 40 and push the hook portion 310 into the first engaging portion 121.

[0075] As Figure 1 and Figure 2 shown, the hook portion 310 is arranged at the upper end of the first clamping member 30, the pressing portion 320 is arranged at the lower end of the first clamping member 30, the connecting shaft 330 is located between the hook portion 310 and the pressing portion 320, and one end of the spring abuts on the area between the hook portion 310 and the connecting shaft 330 on the first clamping member 30.

[0076] In addition, referring to Figure 1 、 Figure 2 and Figure 4, for the convenience of installing the spring, a protruding portion can be formed by locally protruding the top of the inner plug side wall 210 upward, and one end of the spring is abutted against the protruding portion, so that the spring and the pressing portion 320 can be more evenly distributed on both sides of the connecting shaft 330, facilitating the spring to push the first engaging member 30 away from the first engaging portion 121. Of course, the spring can also be arranged downward, with one end of the spring abutted against a portion of the first engaging member 30 below its rotation center line. In this case, the above-mentioned protruding portion may not be provided on the inner plug side wall 210.

[0077] In the case where the first engaging member 30 is swingably connected in the inner plug cavity 230, the first engaging portion 121 can be provided either on the inner surface of the outer cover side wall 120 or on the hanging ribs of the above-mentioned outer cover top wall 110. As long as the position of the first engaging member 30 is adjusted so that it can be inserted into the first engaging portion 121 after swinging.

[0078] In another specific embodiment, the first engaging member 30 can move horizontally in the inner plug cavity 230. At this time, a limiting guide rail (not shown in the figure) is provided on the inner surface of the inner plug bottom wall 220, and the first engaging member 30 moves along the limiting guide rail. This can ensure that the sealing ring accurately pushes the first engaging member 30 into the first engaging portion 121.

[0079] In the case where the first engaging member 30 can move horizontally in the inner plug cavity 230, the first engaging portion 121 can be provided either on the inner surface of the outer cover side wall 120 or on the hanging ribs of the above-mentioned outer cover top wall 110. One end of the limiting guide rail extends towards the direction where the first engaging portion 121 is located, and it is only necessary to guide the hook portion 310 of the first engaging member 30 to be inserted into the first engaging portion 121.

[0080] In this case, a corresponding spring can also be configured so that the spring is located between the inner plug side wall 210 and the first engaging member 30 to push the hook portion 310 away from the first engaging portion 121 under the action of its own elastic force. Grooves 340 can be provided on one side of the first engaging member 30 facing the inner plug side wall 210 and / or on the inner surface of the inner plug side wall 210, and the end of the spring is inserted into the corresponding groove 340. Alternatively, protrusions can be provided on one side of the first engaging member 30 facing the inner plug side wall 210 and / or on the inner surface of the inner plug side wall 210, and the end of the spring is sleeved on the corresponding protrusion.

[0081] Furthermore, in some embodiments, such as Figure 1 , Figure 2 and Figure 3 shown, a stop rib 240 protruding radially is provided on the outer surface of the inner plug side wall 210, and a step 123 is further provided on the inner surface of the outer cover side wall 120 of the outer cover 10. The upper surface of the stop rib 240 abuts against the step 123.

[0082] In these embodiments, during the process of the cup lid assembly covering the top of the cup body 60, the outer lid 10 is pressed downwards, and the seal 50 is squeezed against the inner surface of the cup body 60, realizing the sealed connection between the cup lid assembly and the cup body 60. However, when the seal 50 is pressed, a reaction force is generated and acts on the inner plug 20. Here, the anti-displacement rib 240 is designed to abut and cooperate with the step 123 on the inner side of the outer lid 10, which can effectively prevent the inner plug 20 from moving upwards and improve the installation stability of the inner plug 20.

[0083] In addition, the design of the anti-displacement rib 240 and the step 123 can also achieve a sealing effect, which can block the water vapor or impurities between the outer lid 10 and the inner plug 20 from flowing upwards continuously, so that the parts of the outer lid 10 and the inner plug 20 above the step 123, and the inside of the inner plug 20 are not attached or less attached with impurities, thus facilitating quick and thorough cleaning.

[0084] Specifically, when the first engaging portion 121 is provided on the side wall 120 of the outer lid and is higher than the step 123, the abutting and cooperating of the step 123 and the anti-displacement rib 240 can block the water vapor or impurities from flowing upwards to the first engaging portion 121 and the hook portion 310. Similarly, when the hanging rib of the first engaging portion 121 is provided on the top wall 110 of the outer lid and the projection of the hanging rib on the horizontal plane falls into the inner plug cavity 230, whether the hanging rib is higher than the inner plug cavity 230 or partially extends into the inner plug cavity 230, the abutting and cooperating of the step 123 and the anti-displacement rib 240 can block the water vapor or impurities from entering the top opening of the inner plug cavity 230 upwards, and can avoid or reduce the pollution of the internal components of the inner plug cavity 230.

[0085] As an example, as Figure 3 and Figure 4 shown, the top of the inner plug side wall 210 has a flanging extending outwards, and the flanging is configured as the anti-displacement rib 240. The flanging is convenient to process. Moreover, it can leave a sufficiently high gap between the inner plug side wall 210 and the outer lid side wall 120 for the top of the cup body 60 to be inserted.

[0086] Of course, in other examples, the anti-displacement rib 240 can also be spaced a certain distance from the top of the inner plug side wall 210, and the position of the anti-displacement rib 240 can be designed according to needs.

[0087] Furthermore, as Figure 1 and Figure 3 shown, a connecting thread 125 is provided at a position on the inner surface of the outer lid side wall 120 below the step 123, and the connecting thread 125 is used for screwing and connecting with the top of the cup body 60. The cup lid assembly and the cup body 60 are firmly connected and not easy to leak water. A vertical extending limiting rib 124 is provided on one of the step 123 and the anti-displacement rib 240, and a limiting groove 241 cooperating with the limiting rib 124 is provided on the other.

[0088] When the outer cover 10 and the cup body 60 are screwed together, during the process of screwing the outer cover 10, there is a risk that the inner plug 20 rotates relative to the outer cover 10, which easily causes damage to the connection relationship between the two. Therefore, by vertically inserting the limiting rib 124 into the limiting groove 241, it can be ensured that the outer cover 10 and the inner plug 20 rotate synchronously, thereby improving the connection stability between the two.

[0089] As Figure 3 and Figure 4 shown, on the step 123 of the outer cover 10, there is a vertically extending limiting rib 124, and a limiting groove 241 is provided on the stop rib 240 for the limiting rib 124 to be inserted. The limiting groove 241 can vertically penetrate the stop rib 240 or horizontally penetrate the outer edge of the stop rib 240.

[0090] Furthermore, in some embodiments, as Figure 1 , Figure 2 and Figure 4 shown, a second engaging portion 122 is provided at a position in the outer cover 10 opposite to the first engaging portion 121, and a second engaging member 250 is provided on one side of the inner plug 20 opposite to the first engaging member 30. The second engaging member 250 can be engaged into the second engaging portion 122, and the second engaging member 250 is fixedly connected to the inner plug 20.

[0091] In these embodiments, the inner plug 20 and the outer cover 10 are connected by the relatively distributed first engaging member 30 and the second engaging member 250, and the connection stability is good. Moreover, the second engaging member 250 is fixedly connected to the inner plug 20, and the connection is firm, which is conducive to the stable connection of the inner plug 20 to the outer cover 10.

[0092] Among them, one of the second engaging portion 122 and the second engaging member 250 includes a card slot, and the other includes a hook portion that cooperates with the card slot. The structure is simple and convenient for processing.

[0093] In a specific application, when disassembling the inner plug assembly, the sealing ring can be disassembled first to separate the first engaging member 30 from the first engaging portion 121. At this time, when pulling down the inner plug assembly, the second engaging member 250 can be easily separated from the second engaging portion 122, which is convenient for disassembling the inner plug assembly. When installing the inner plug assembly, a sealing ring is sleeved on the inner plug 20 on which the first engaging member 30 and the elastic member 40 have been installed, and the first engaging member 30 is roughly aligned with the first engaging portion 121 in advance. The hook portion 310 of the first engaging member 30 is inserted into the first engaging portion 121 by using the sealing ring to push. Then, the inner plug 20 is pressed hard. When a clicking sound is heard, that is, when the second engaging member 250 is engaged with the second engaging portion 122, it means that the inner plug assembly and the outer cover 10 have been installed together.

[0094] As an example, the second engaging member 250 and the inner plug 20 are integrally formed. The connection between the two is firm and the processing is convenient.

[0095] As an example, when the first engaging portion 121 and the second engaging portion 122 are provided on the outer cover side wall 120, as Figure 4 shown, the second engaging member 250 is vertically extended from the top of the inner plug side wall 210 and then horizontally bent, and extends in the direction of the second engaging portion 122. The structure is simple and convenient for processing.

[0096] In addition, when a retaining rib 240 is provided on the outer surface of the inner plug side wall 210, a step 123 is provided on the inner surface of the outer cover side wall 120, and when the first engaging portion 121 and the second engaging portion 122 are provided on the outer cover side wall 120 and are higher than the step 123, in order to prevent the first engaging member 30 and the second engaging member 250 from interfering with the step 123 during the process of inserting the inner plug 20 into the outer cover 10, the part of the step 123 corresponding to the first engaging member 30 and the second engaging member 250 can have a notch, which facilitates the hook portion 310 of the first engaging member 30 and the second engaging member 250 to move above the step 123 through the notch and move to the height where the first engaging portion 121 and the second engaging portion 122 are located, so as to facilitate the first engaging member 30 and the second engaging member 250 to be inserted into the corresponding first engaging portion 121 and second engaging portion 122.

[0097] Furthermore, in some embodiments, as Figure 1 、 Figure 2 and Figure 4 shown, the top of the first engaging member 30 is bent to one side to form a hook portion 310. The hook portion 310 has a simple structure and is convenient for processing.

[0098] Furthermore, in some embodiments, as Figure 1 、 Figure 2 and Figure 4 shown, the bottom of the first engaging member 30 is bent to one side to form an extrusion portion 320, and the extrusion portion 320 extends into the avoidance opening 211. The extrusion portion 320 has a simple structure and is convenient for processing.

[0099] Furthermore, in some embodiments, as Figure 1 and Figure 2 shown, the bottom of the inner plug side wall 210 has a circumferentially distributed mounting groove 214, the avoidance opening 211 penetrates the bottom wall of the mounting groove 214, the inner side of the sealing ring has a convex rib 510, and the convex rib 510 is inserted into the mounting groove 214 and presses the extrusion portion 320.

[0100] In these embodiments, ribs 510 are provided on the sealing ring. By inserting the ribs 510 into the installation groove 214 on the side wall of the inner plug 210, the installation stability of the sealing ring can be improved, and the sealing ring can be prevented from easily falling off the inner plug 20. Moreover, the ribs 510 of the sealing ring are directly used to squeeze the squeezing portion 320, and the avoidance opening 211 is directly formed on the groove wall of the installation groove 214, without the need for a large-area improvement of the inner plug 20, which is beneficial to ensuring the structural strength of the inner plug 20.

[0101] Further, in some embodiments, as Figure 1 shown, the bottom of the sealing ring has a protruding handle portion 520, which is convenient for the user to hold the handle portion 520 to disassemble the sealing ring.

[0102] The second aspect embodiment of the present invention provides a water cup, which includes a cup body 60 and a cup cover assembly as described in any one of the above embodiments. The cup cover assembly is detachably covered at the top opening of the cup body 60.

[0103] The water cup provided by the embodiment of this aspect has the beneficial effects of any one of the above embodiments due to having the cup cover assembly as described in any one of the above embodiments, and will not be elaborated here.

[0104] Although the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope of the present invention. It should be understood that in the view of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention defined by the claims.
