Description

Technical Field

[0001] This utility model relates to the field of password cup technology, and in particular to a password cup lid assembly and a password cup. Background Technology

[0002] A password cup is a cup with a combination lock or fingerprint unlocking function. The password or fingerprint unlocking function can ensure that only the user or authorized personnel can open the cup, effectively preventing others from accidentally drinking from or stealing the beverage in the cup, and protecting the safety of personal beverages.

[0003] In related technologies, the combination lock cup's password is set on the lid. The lid is placed over the rim of the cup, with the top cover locking onto the bottom cover. Unlocking requires a password. However, since the bottom cover is threaded onto the cup body, rotating the thread in one direction locks it in, and rotating it in the other direction unlocks it. But if, after the top cover is locked onto the bottom cover, the bottom cover can still be detached from the cup body by threading it, then the safety of the beverage inside remains compromised, rendering the combination lock on the lid meaningless. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a cup lid assembly for a password cup and a password cup. When the upper and lower lids of the cup lid assembly are closed, a limiting component allows the second lid and the lower lid of the cup lid assembly to rotate relative to each other, but the second lid cannot rotate when the first lid is closed.

[0005] The technical solution adopted by this utility model to solve its problem is: A lid assembly for a password-protected cup includes, A first cover, comprising an upper cover and a lower cover, wherein the upper cover and the lower cover are movably connected, and the lower cover is provided with a drinking opening; the upper cover is used to open or close the drinking opening. The second cover is rotatably connected to the lower cover, and the second cover is provided with a drinking outlet, which is correspondingly provided with the drinking opening. A limiting mechanism is provided, comprising a switch, a first limiting member, and a second limiting member. The switch is disposed on the upper cover, the first limiting member is disposed on the lower cover, and the second limiting member is disposed on the second cover body. The second limiting member can move closer to or away from the first limiting member. The second limiting member is used to connect with the first limiting member after moving closer to the first limiting member, so that the second cover body and the lower cover are linked. The switch is used to drive the first limiting member away from the second limiting member when the upper cover closes the drinking opening.

[0006] As an optional implementation, the first limiting member includes a limiting slider, which is slidably mounted on the lower cover; the second limiting member includes a limiting protrusion; the limiting slider is provided with a limiting groove, and the limiting protrusion is used to extend into or out of the limiting groove when the limiting slider slides.

[0007] As an optional implementation, the lower cover is provided with a through hole; the upper end of the limiting slider is provided with a pressure block, the pressure block is slidably connected to the through hole and is used to be pressed by the switch; the switch is used to press the pressure block when the upper cover closes the drinking opening.

[0008] As an optional implementation, the switching element includes a pressing protrusion, the pressing protrusion being provided with a pressing inclined surface, and the pressure receiving block being provided with a pressure receiving inclined surface, the pressure receiving inclined surface slidingly engaging with the pressing inclined surface.

[0009] As an optional implementation, the second limiting member includes a plurality of limiting protrusions, which are spaced apart in the circumferential direction of the second cover.

[0010] As an optional implementation, the limiting mechanism further includes a first elastic member, one end of which is connected to the lower cover and the other end of which is connected to the first limiting member. The first elastic member is used to provide a first elastic stress that drives the first limiting member toward the second limiting member.

[0011] As an optional implementation, the cup lid assembly further includes a linkage mechanism, which includes a first linkage member and a second linkage member. The first linkage member is connected to the lower cover, and the second linkage member is disposed on the second cover body. The first linkage member is used to move closer to the second linkage member and abut against the second linkage member when the lower cover rotates about a locking direction.

[0012] As an optional implementation, the first linkage component includes a linkage rod and a second elastic component. The linkage rod is connected to the lower cover through the second elastic component. The second cover is provided with a linkage step and a guide surface. The guide surface extends along the locking direction and is an inclined surface or a spiral surface. The linkage step is provided at one end of the guide surface. The linkage rod slides with the guide surface and can slide along the locking direction until it abuts against the linkage step.

[0013] As an optional implementation, the upper cover is provided with a latch, and the lower cover is provided with a locking slot, with the latch corresponding to the locking slot; The cup lid assembly also includes a password module and a driving component. The driving component is used to activate the password module after it receives a password, and to move the latch away from the lock opening.

[0014] A password cup includes the aforementioned cup lid assembly and a cup body, wherein the second lid body is threadedly connected to the rim of the cup body.

[0015] In summary, this utility model has the following technical effects: 1. The second limiting member on the second lid, which connects to the cup body, can only be linked with the first limiting member on the lower lid after the upper and lower lids are opened. This allows the lid assembly to be rotated and removed for adding beverages, or rotated for assembly. After assembly, when the upper lid slides to the drinking spout position with the lower lid closed, the second limiting member on the second lid disengages from the first limiting member on the lower lid. Therefore, in the closed state, only the user can remove the lid assembly to add beverages when opening the upper lid, improving the safety of the beverage inside the cup.

[0016] 2. When used in a combination lock cup, after the top and bottom lids are closed, a combination password is required to open the cup, enhancing beverage safety. In the closed state, because the bottom lid and the second lid can rotate relative to each other, operating the bottom lid will not allow the second lid to rotate, preventing it from detaching from the cup. In other words, the lid assembly cannot be removed when the top and bottom lids are closed. Drinking or adding beverages can only be done after entering the combination password, making it safer to use. Attached Figure Description

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] See Figures 1-10 This utility model discloses a cup lid assembly 1 for a password cup, including a first lid body 10, a second lid body 20, and a limiting mechanism. The first lid body 10 includes an upper lid 11 and a lower lid 12, and the upper lid 11 and the lower lid 12 are movably connected. A drinking opening is provided on the lower lid 12. During the movement of the upper lid 11 relative to the lower lid 12, the upper lid 11 opens or closes the drinking opening. For example, the upper lid 11 can be hinged to the lower lid 12, allowing the drinking opening to be opened or closed by rotation; or the upper lid 11 can be slidably mounted on the lower lid 12, allowing the drinking opening to be opened or closed by sliding.

[0027] The second cover 20 is rotatably connected to the lower cover 12. Specifically, the second cover 20 can be fitted onto the outside of the lower cover 12 and can rotate relative to it. The second cover 20 is provided with a drinking outlet 21, which corresponds to the drinking opening. When the second cover 20 is connected to the cup body 2, water in the cup body 2 can be discharged through the drinking outlet 21 of the second cover 20 and then guided to the drinking opening through the drinking outlet 21 to achieve normal drinking. When drinking is not required, the upper cover 11 can be moved to the position that closes the drinking opening of the lower cover 12.

[0028] The limiting mechanism includes a switch 33, a first limiting member 31, and a second limiting member 32. The switch 33 is disposed on the upper cover 11, the first limiting member 31 is disposed on the lower cover 12, and the second limiting member 32 is disposed on the second cover 20. The second limiting member 32 can move closer to or away from the first limiting member 31. After moving closer to the first limiting member 31, the second limiting member 32 connects with the first limiting member 31 so that the second cover 20 and the lower cover 12 are linked. When the upper cover 11 closes the drinking opening, the switch 33 can drive the first limiting member 31 away from the second limiting member 32.

[0029] Based on the above structure, when using the cup lid assembly 1 of the password cup of this utility model, the second cover 20 of the cup lid assembly 1 can be threadedly rotated and assembled with the cup mouth 201 of the cup body 2.

[0030] When the cup lid assembly 1 is assembled to the cup opening 201 of the cup body 2, since the lower cover 12 is fitted outside the second cover 20, the user needs to hold the outer lower cover 12 to rotate the inner second cover 20 relative to the cup opening 201 of the cup body 2. The lower cover 12 and the second cover 20 are in a rotating assembly relationship. In order to make the two work together, the upper cover 11 needs to be moved away from the drinking outlet 21 of the lower cover 12, that is, the upper cover 11 opens the lower cover 12. At this time, the switch 33 on the second cover 20 is not in contact with the first limiting member 31. The second limiting member 32 can move close to the first limiting member 31 on the lower cover 12. After the second limiting member 32 moves with the first limiting member 31, the second cover 20 is connected to the lower cover 12. When the user operates the lower cover 12 to rotate, the second cover 20 inside the lower cover 12 can be rotated together, so that the cup lid assembly 1 can be assembled onto the cup body 2.

[0031] After the cup lid assembly 1 is assembled to the cup body 2, when there is no need to drink water, by moving the upper cover 11 to the position where the drinking opening of the lower cover 12 is closed, in this state, the switch 33 on the upper cover 11 can drive the first limiting member 31 on the lower cover 12 to separate from the second limiting member 32 of the second cover 20. At this time, the lower cover 12 is disengaged from the second cover 20 and is not linked. Therefore, when the user operates the lower cover 12 located on the outside to rotate, the lower cover 12 can also rotate relative to the second cover 20 without driving the second cover 20 to rotate. Thus, when the drinking opening is open with the upper cover 11 closed, the user cannot rotate the second cover 20 by rotating the lower cover 12. Therefore, in this state, the cup lid assembly 1 cannot be disengaged from the cup body 2, and there will be no safety issues with the beverage due to the cup lid assembly 1 being removed.

[0032] In other words, the second limiting member 32 on the second cover 20, which is connected to the cup body 2, can only be linked with the first limiting member 31 of the lower cover 12 after the upper cover 11 and the lower cover 12 are opened, allowing the cup lid assembly 1 to be rotated and removed for beverage addition, or rotated for assembly. After assembly, when the upper cover 11 slides to the state of closing the drinking outlet 21 of the lower cover 12, the second limiting member 32 of the second cover 20 disengages from the first limiting member 31 of the lower cover 12. Therefore, in the closed state, only the user can remove the cup lid assembly 1 to add beverage when opening the upper cover 11.

[0033] Especially when applied to a combination lock cup, after the upper lid 11 is closed to the lower lid 12, a combination lock operation is required before it can be opened to improve the safety of drinking beverages. In the closed state, since the lower lid 12 and the second lid 20 can rotate relative to each other, operating the lower lid 12 cannot rotate the second lid 20. The second lid 20 cannot detach from the cup body 2. That is, when the upper lid 11 and lower lid 12 are closed, the cup lid assembly 1 cannot be removed. Drinking or adding beverages can only be done after a combination lock operation, making it safer to use.

[0034] As an optional implementation, the first limiting member 31 includes a limiting slider, which is slidably mounted on the lower cover 12. The corresponding second limiting member 32 includes a limiting protrusion. Specifically, the limiting slider is provided with a limiting groove 312, and the limiting protrusion can extend into and exit the limiting groove 312 when the limiting slider slides.

[0035] Based on this structure, when the upper cover 11 opens the lower cover 12, the switch 33 of the upper cover 11 separates from the limiting slider, allowing the limiting slider to move towards the limiting protrusion. The limiting groove 312 of the limiting slider allows the limiting protrusion to extend into it, causing the lower cover 12 to move in conjunction with the second cover 20. Thus, the movement of the lower cover 12 can drive the second cover 20 to rotate and open the cup lid assembly 1 for adding water. When the upper cover 11 moves to close the drinking opening of the lower cover 12, the switch 33 on the upper cover 11 moves towards the limiting slider, pushing the limiting slider away from the limiting protrusion during the closing process. The limiting groove 312 of the limiting slider can then separate from the limiting protrusion, and the lower cover 12 separates from the second cover 20. If the lower cover 12 is rotated, it will also rotate relative to the second cover 20. Therefore, the cup lid assembly 1 cannot be removed when the upper cover 11 and the lower cover 12 are closed.

[0036] As an optional implementation, a through-hole 123 is provided in the lower cover 12, and a pressure block 311 is provided at the upper end of the limiting slider. The pressure block 311 is slidably connected to the through-hole 123 and is used to be pressed by the switch member 33. The switch member 33 can press the pressure block 311 when the upper cover 11 closes the drinking opening. That is, the pressure block 311 on the limiting slider of the first limiting member 31 can extend out of the surface of the lower cover 12 through the through hole 123. When the upper cover 11 and the lower cover 12 are closed, the switch member 33 on the upper cover 11 can approach the pressure block 311 and push the limiting slider away from the limiting protrusion during the closing process. The limiting groove 312 of the limiting slider can then separate from the limiting protrusion, and the lower cover 12 will separate from the second cover 20. If the lower cover 12 is rotated, then the lower cover 12 will also rotate relative to the second cover 20. Therefore, the cup lid assembly 1 cannot be removed when the upper cover 11 and the lower cover 12 are closed.

[0037] More specifically, the switch 33 includes a pressing protrusion with a pressing slope, and a pressure block 311 with a pressure slope. The pressure slope and the pressing slope slide together. When the upper cover 11 closes the lower cover 12, the pressing protrusion on the upper cover 11 can press the pressure block 311 of the limiting slider during the closing process. The pressing action is achieved by the slope cooperation, which decomposes the longitudinal force into a transverse force. This can drive the limiting slider away from the limiting protrusion, thereby separating the limiting groove 312 of the limiting slider from the limiting protrusion.

[0038] It should be noted that when the movable connection between the upper cover 11 and the lower cover 12 is selected as a hinged connection, when the upper cover 11 closes the lower cover 12, the upper cover 11 can rotate downwards to close with the lower cover 12. The switch 33 on the upper cover 11 can then press down on the pressure block 311 of the limiting slider on the lower cover 12. The downward force is decomposed into a lateral force by the pressure inclined surface, driving the limiting slider away from the limiting protrusion.

[0039] Of course, when the upper cover 11 and the lower cover 12 are slidably connected, the switch 33 of the upper cover 11 can slide closer to or further away from the limiting slider, and after moving closer to the limiting slider, it can push the limiting slider away from the limiting protrusion, causing the limiting slider to separate from the limiting protrusion.

[0040] As an optional implementation, the second limiting member 32 includes multiple limiting protrusions, which are spaced apart in the circumferential direction of the second cover 20. Based on this structure, since multiple limiting protrusions are provided, when the cup lid assembly 1 is closed with the upper cover 11 and the lower cover 12, since the lower cover 12 can rotate relative to the second cover 20, even if the first limiting member 31 on the lower cover 12 rotates to be misaligned with one of the limiting protrusions, it can still correspond to the limiting protrusions at different positions on the second cover 20. This facilitates the alignment of the limiting slider and the limiting protrusions at different angles, and facilitates the subsequent disassembly of the cup lid assembly 1.

[0041] As an optional implementation, the limiting mechanism further includes a first elastic member 34, one end of which is connected to the lower cover 12 and the other end of which is connected to the first limiting member 31. The first elastic member 34 is used to provide a first elastic stress, which can drive the first limiting member 31 to move closer to the second limiting member 32.

[0042] Based on this structure, when the upper cover 11 opens the lower cover 12, the first elastic stress provided by the first elastic member 34 can drive the first limiting member 31 to move closer to the second limiting member 32, so that the first limiting member 31 and the second limiting member 32 are linked. That is, during the opening action, the first elastic member 34 acts to keep the lower cover 12 and the second cover body 20 in a linked state. When the upper cover 11 and the lower cover 12 are closed, the switch member 33 of the upper cover 11 can press against the first limiting member 31, driving the first limiting member 31 away from the second limiting member 32. At this time, the first elastic member 34 can be compressed to keep the first limiting member 31 in a reset state. Once the upper cover 11 is opened, the first elastic stress provided by the first elastic member 34 can drive the first limiting member 31 to quickly reset to the state connected with the second limiting member 32, which facilitates the removal of the cup lid assembly 1.

[0043] Of course, without the first elastic component 34, after the upper cover 11 opens the lower cover 12, the pressure block 311 of the first limiting component 31 can be manually moved to drive the first limiting component 31 closer to the second limiting component 32.

[0044] As an optional implementation, the cup lid assembly 1 also includes a linkage mechanism, which includes a first linkage member and a second linkage member, wherein the first linkage member is connected to the lower cover 12 and the second linkage member is disposed on the second cover body 20.

[0045] Specifically, when the upper cover 11 is closed to the lower cover 12, the first limiting member 31 of the lower cover 12 moves away from the second limiting member 32 under the action of the opening and closing member 33 of the upper cover 11. At this time, if the lower cover 12 is operated from the outside, even if the lower cover 12 can rotate, it cannot drive the second cover body 20 inside to rotate, so the cup lid assembly 1 cannot be disassembled.

[0046] It should be noted that when the second cover 20 of the cup lid assembly 1 is assembled with the cup body 2, the lower cover 12 drives the second cover 20 to rotate relative to the cup body 2 in the locking direction. If the second cover 20 of the cup lid assembly 1 is not fully tightened to the cup body 2 after being connected, the lower cover 12 needs to continue rotating in the locking direction to tighten it. Therefore, in this application, after the upper cover 11 and the lower cover 12 are closed, the first limiting member 31 on the lower cover 12 separates from the second limiting member 32 of the second cover 20. At this time, when the lower cover 12 is operated by hand, the first linkage member on the lower cover 12 can rotate in the locking direction toward the second linkage member on the second cover 20. After the first linkage member rotates to be close to the second linkage member and abuts against the second linkage member, the lower cover 12 can continue to rotate in the locking direction, so that the first linkage member links the second linkage member, driving the inner second cover 20 to continue rotating in the locking direction.

[0047] That is, when the upper cover 11 and the lower cover 12 are closed, the lower cover 12 can still be operated to further tighten the inner second cover 20 relative to the cup body 2, so that the cup lid assembly 1 can be locked. However, when the upper cover 11 and the lower cover 12 are closed, the first linkage can only abut against the second linkage when the lower cover 12 is rotated in the locking direction, thereby driving the second cover 20 to be further locked in the locking direction. When rotated in the opposite direction of the locking direction (the loosening direction), the first linkage separates from the second linkage, and the lower cover 12 cannot drive the inner second cover 20 to rotate at this time, that is, it cannot be loosened in the closed state, which can also ensure that the beverage is safe to drink in the closed state.

[0048] More specifically, the first linkage component includes a linkage rod 43 and a second elastic component 44. The linkage rod 43 is connected to the lower cover 12 through the second elastic component 44. Correspondingly, a linkage step 41 and a guide surface 42 are provided on the second cover 20. The guide surface 42 extends along the locking direction and is an inclined surface or a spiral surface. The linkage step 41 is set at one end of the guide surface 42, and the linkage rod 43 slides with the guide surface 42 and can slide along the locking direction until it abuts against the linkage step 41.

[0049] Based on this structure, when the upper cover 11 and the lower cover 12 are closed, the lower cover 12 rotates, and the linkage rod 43 on the lower cover 12 can slide along the guide surface 42. Under the action of the second elastic stress of the second elastic member 44, the linkage rod 43 remains in a downward and tight state against the guide surface 42. After the linkage rod 43 slides downward along the inclined plane or spiral surface until it abuts against the linkage step 41, it can drive the second cover 20 to rotate in the locking direction. When the lower cover 12 rotates in the opposite direction, the linkage rod 43 slides upward along the inclined plane or spiral surface, the second elastic member 44 is compressed, and the linkage rod 43 separates from the linkage step 41.

[0050] As an optional implementation, the upper cover 11 is provided with a latch 112, and the lower cover 12 is provided with a locking slot, with the latch 112 corresponding to the locking slot. The cup lid assembly 1 also includes a password module 111 and a driving component. The driving component can be activated after the password module receives the password, and the driving component can drive the latch 112 away from the locking slot.

[0051] When the upper cover 11 and the lower cover 12 are closed, the latch 112 can be locked inside the lock opening. When unlocking, the password module 111 can receive password authentication, such as fingerprint password or numeric password. After receiving the password, the drive unit can be activated to move the latch 112 away from the lock opening, so that the upper cover 11 and the lower cover 12 can be opened.

[0052] It should be noted that the password module 111 may include a control board, on which a password is preset. The upper cover 11 is equipped with a password input structure. After the password is entered, the controller receives the password information and controls the opening of the drive component. This part belongs to the prior art and is not the technical content to be protected in this application, so it will not be described in detail here.

[0053] To facilitate the assembly of the password module 111 and the driving component into the upper cover 11, an assembly cavity is provided inside the upper cover 11, and a disassembly port is provided at the top of the upper cover 11. The password module 111 and the driving component are inserted into or removed from the assembly cavity through the disassembly port. A power source (such as a battery structure) can also be installed in the assembly cavity. After the operation is completed, the disassembly port can be sealed with a cover plate 113 to prevent the internal structure from being exposed.

[0054] Example 2, like Figures 1-12 The illustrated password cup includes a cup lid assembly 1 and a cup body 2, with a second lid 20 threadedly connected to the cup mouth 201 of the cup body 2.

[0055] In use, the second lid 20 of the cup lid assembly 1 can be threadedly rotated onto the cup opening 201 of the cup body 2. When the cup lid assembly 1 is assembled onto the cup opening 201 of the cup body 2, since the lower cover 12 is fitted outside the second lid 20, the user needs to hold the outer lower cover 12 to rotate the inner second lid 20 relative to the cup opening 201 of the cup body 2. Furthermore, the lower cover 12 and the second lid 20 are in a rotating assembly relationship. To enable them to move together, the upper cover 11 needs to be moved away from the lower cover 12. When the drinking outlet 21 is in the state of the upper cover 11 and the lower cover 12 is open, the switch 33 on the second cover 20 is not in contact with the first limiting member 31. The second limiting member 32 can move close to the first limiting member 31 on the lower cover 12. After the second limiting member 32 moves with the first limiting member 31, the second cover 20 is connected to the lower cover 12. When the lower cover 12 is rotated by hand, the second cover 20 inside the lower cover 12 can be rotated together, so that the cup lid assembly 1 can be assembled onto the cup body 2.

[0056] After the cup lid assembly 1 is assembled to the cup body 2, when there is no need to drink water, by moving the upper cover 11 to the position where the drinking opening of the lower cover 12 is closed, in this state, the switch 33 on the upper cover 11 can drive the first limiting member 31 on the lower cover 12 to separate from the second limiting member 32 of the second cover 20. At this time, the lower cover 12 is disengaged from the second cover 20 and is not linked. Therefore, when the user operates the lower cover 12 located on the outside to rotate, the lower cover 12 can also rotate relative to the second cover 20 without driving the second cover 20 to rotate. Thus, when the drinking opening is open with the upper cover 11 closed, the user cannot rotate the second cover 20 by rotating the lower cover 12. Therefore, in this state, the cup lid assembly 1 cannot be disengaged from the cup body 2, and there will be no safety issues with the beverage due to the cup lid assembly 1 being removed.

[0057] When applied to a combination lock cup, after the upper lid 11 is closed to the lower lid 12, a combination lock operation is required before it can be opened to enhance beverage safety. In the closed state, since the lower lid 12 and the second lid 20 can rotate relative to each other, operating the lower lid 12 cannot rotate the second lid 20. Therefore, the second lid 20 cannot detach from the cup body 2. In other words, with the upper lid 11 and lower lid 12 closed, the lid assembly 1 cannot be removed. Drinking or adding beverages can only be done after a combination lock operation, making it safer to use.

[0058] It should be noted that the other structures of the cup lid assembly 1 in this embodiment are the same as those in embodiment 1. When applied to the password cup, the function and effect are the same as those in embodiment 1, and will not be described in detail here.

[0059] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
