The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] like Figure 1-8 The image shows an embodiment provided by this utility model.

[0035] This utility model embodiment provides a cup lid for covering a cup. The cup lid includes: a connecting seat 1, an inner lid 2, and an outer lid 4. The bottom of the connecting seat 1 is provided with an internal thread 12 for threaded connection with the cup. The connecting seat 1 is provided with a suction tube 10, and the top of the connecting seat 1 is provided with a connecting part 11. The bottom cavity of the inner lid 2 is provided, and the inner lid 2 is rotatably fitted onto the connecting seat 1. A slidable limiting member 3 is provided in the bottom cavity of the inner lid 2. One end of the limiting member 3 passes through the inner lid 2 and is located at the top of the inner lid 2. The limiting member 3 can engage with the connecting seat 1. The connecting part 11 is connected, and the top of the inner cover 2 is also provided with a buckle 22. The inner cover 2 is provided with a through hole for the suction tube 10 to pass through. One end of the outer cover 4 is rotatably connected to the inner cover 2, and the other end of the outer cover 4 is provided with a fingerprint recognition mechanism 40. By flipping the outer cover 4, the bottom of the outer cover 4 can cover the top of the inner cover 2 and the suction tube 10. The bottom of the outer cover 4 is provided with a limiting mechanism 41 that engages with the buckle 22. The limiting mechanism 41 is signal connected to the fingerprint recognition mechanism 40. The fingerprint recognition mechanism 40 drives the limiting mechanism 41 to engage with the buckle 22.

[0036] Specifically, the bottom of the connecting seat 1 is a hollow structure, and the inner wall of the bottom cavity of the connecting seat 1 is provided with an internal thread 12 to facilitate threaded connection to the cup body; the bottom cavity of the inner cover 2 is also hollow, and the depth of the bottom cavity of the inner cover 2 is greater than the thickness of the connecting seat 1, so that after the inner cover 2 is fitted onto the connecting seat 1, the inner cover 2 completely covers the connecting seat 1. Since the inner cover 2 and the connecting seat 1 are rotatably connected, rotating the inner cover 2 cannot drive the connecting seat 1 to rotate together, thus preventing accidental drinking by the user directly drinking the liquid in the cup by opening the connecting seat 1; in order to facilitate adding liquid to the cup, a sliding limiting member 3 is provided on the inner cover 2, and a connecting part 11 connected to the limiting member 3 is provided on the connecting seat 1. By sliding the limiting member 3, the limiting member 3 and the connecting part 11 are engaged, thereby connecting the inner cover 2 and the connecting seat 1. At this time, the inner cover can be screwed on. 2 can drive the connecting seat 1 to rotate together, thereby releasing the threaded connection between the connecting seat 1 and the cup; In this embodiment, a flip-out outer cover 4 is also provided on the top of the inner cover 2, and a fingerprint recognition mechanism 40 and a limiting mechanism 41 are provided inside the outer cover 4. Both the fingerprint recognition mechanism 40 and the limiting mechanism 41 adopt existing technology. The fingerprint recognition mechanism 40 collects the user's fingerprint information. If the person using the cup has the corresponding user's fingerprint information, the locking between the limiting mechanism 41 and the buckle can be released, thereby releasing the restriction between the outer cover 4 and the inner cover 2. At this time, the spout tube 10 is exposed, and the cup owner can drink the liquid in the cup through the spout tube 10. If it is necessary to replenish the liquid in the cup, the inner cover 2 and the connecting seat 1 can be connected by operating the limiting member 3 at the exposed end of the top of the inner cover 2. At this time, turning the inner cover 2 can release the threaded connection between the connecting seat 1 and the cup.

[0037] In this embodiment, the outer cover 4 has a driving cavity 43 inside, and the bottom of the outer cover 4 has a clearance opening 44 that connects to the driving cavity 43. The fingerprint recognition mechanism 40 is a fingerprint recognition module. The limiting mechanism 41 is disposed in the driving cavity 43. The limiting mechanism 41 includes a circuit board 410, a motor 411, a transmission shaft 412, a swing arm 413, a torsion spring 414, and a battery 418. The swing arm 413 is arranged along the axial direction of the outer cover 4, and its middle part is hinged to the inner wall of the driving cavity 43. The bottom end of the swing arm 413 extends into the clearance opening 44 and is provided with a locking mechanism. Hook 415 and torsion spring 414 are set at the hinge of swing arm 413. Drive shaft 412 is set along the vertical direction of swing arm 413 and is rotatably connected to the inner wall of drive cavity 43. The end of drive shaft 412 is adjacent to the upper end of swing arm 413 and has a toggle block 416 radially provided. Motor 411 is fixedly connected to the inner wall of drive cavity 43. Its output shaft is driven by the front end of drive shaft 412 through helical gear 417. Battery 418 supplies power to fingerprint recognition module and motor 411 through circuit board 410. When the outer cover 4 When the inner cover 2 is closed, the latch 22 extends into the clearance opening 44 and pushes the swing arm 413 to swing and avoid it through the inclined surface of the bent end of the hook 415 until the hook 415 aligns with the latch 22. At this point, the swing arm 413 will return to its original position under the drive of the torsion spring 414, causing the hook 415 to engage with the latch 22. This prevents the outer cover 4 from flipping open relative to the inner cover 2, thus fixing it closed on the inner cover 2. When the user needs to drink water, they only need to touch the fingerprint recognition module. The correct fingerprint information triggers the circuit board 410, at which point the power... The circuit board 410 controls the motor 411 to rotate, and the motor 411 drives the transmission shaft 412 to rotate. The transmission shaft 412 drives the toggle block 416 to move the upper end of the swing arm 413, thereby driving the swing arm 413 to swing and drive the hook 415 to disengage from the buckle 22 so that the user can open the outer cover 4. The motor 411 can preset the time for the swing arm 413 to swing and hover, such as 5 seconds. After 5 seconds, the driving force is released, and the swing arm 413 will be reset under the drive of the torsion spring 414 so that it can be engaged with the buckle 22 again. This cycle is repeated.

[0038] In one embodiment, the fingerprint recognition mechanism 40 is a fingerprint recognition module, which is embedded on one side of the outer cover 4. The limiting mechanism 41 includes a hook for engaging the buckle 22 and a motor. The outer cover 4 has a hollow structure, and the motor is built into the inner cavity of the outer cover 4 and electrically connected to the fingerprint recognition module. A groove is formed radially at the bottom of the outer cover 4 to connect to the inner cavity of the outer cover 4. The hook is slidably connected in the groove, and its top end extends into the inner cavity of the outer cover 4 and is connected to a rack along its sliding direction. The bottom end of the hook extends to the bottom of the outer cover 4 and is hook-shaped. The output end of the motor meshes with the rack through a gear. The user can control the motor through the fingerprint recognition module. The motor rotates forward or backward. If a preset program is provided for the fingerprint recognition module, when the user triggers the fingerprint recognition module for the first time, the motor is controlled to rotate forward. When the user triggers the fingerprint recognition module for the second time, the motor is controlled to rotate backward. This cycle repeats. After the fingerprint recognition module is triggered by the correct fingerprint information, the fingerprint recognition module will send a drive signal to the motor to control the motor to rotate. Through gear and rack transmission, the hook moves along the slide groove, so that its bottom end engages or disengages from the buckle 22. This allows the user to lock the outer cover 4 onto the inner cover 2 to prevent others from easily opening the outer cover 4 and causing misuse, or to disconnect the outer cover 4 from the inner cover 2 and open the outer cover 4 to drink water (not shown in the attached figure).

[0039] In one embodiment, the fingerprint recognition mechanism 40 is a fingerprint recognition module, which is embedded on one side of the outer cover 4. The limiting mechanism 41 includes a hook for engaging the buckle 22, a spring, a control module, and a bidirectional memory titanium alloy wire electrically connected to the control module. The outer cover 4 has a hollow structure, and the spring, control module, and titanium alloy wire are all built into the inner cavity of the outer cover 4. The control module is electrically connected to the fingerprint recognition module. A groove is radially formed at the bottom of the outer cover 4, which connects to the inner cavity of the outer cover 4. The hook is slidably connected in the groove, with its top end extending into the inner cavity of the outer cover 4 and fixedly connected to the end of the titanium alloy wire away from the control module. The bottom end of the hook extends to the bottom of the outer cover 4 and is hook-shaped. When the control module powers the titanium alloy wire, the titanium alloy wire will instantly... When heated, the titanium alloy wire contracts, pulling the hook to slide. At this time, the hook compresses the spring. After the power is cut off, the titanium alloy wire will return to its original position, and the spring will release energy and reset, driving the hook to slide along the groove to reset. Utilizing this feature, under the preset program of the fingerprint recognition module, when the user triggers the fingerprint recognition module for the first time with the correct fingerprint information, the fingerprint recognition module will send a control signal to the control module. The control module will then energize the titanium alloy wire, thereby causing the hook to slide and disengage its bottom end from the latch 22, thus releasing the connection between the outer cover 4 and the inner cover 2, so that the outer cover 4 can be opened for drinking water. After the discharge ends, the hook slides back to its original position under the drive of the spring, so that its bottom end engages with the latch 22, thereby locking the outer cover 4 onto the inner cover 2 to prevent others from easily opening the outer cover 4 and causing misuse (attached diagram not shown).

[0040] Both of the above locking schemes can be controlled by the chip built into the fingerprint recognition module. The specific control logic can be adjusted according to the actual application. Such control programs are existing technologies and will not be described in this embodiment.

[0041] In summary, this embodiment uses a fingerprint recognition mechanism 40 on the outer cover 4 to identify the owner's fingerprint information. Once the fingerprint recognition mechanism 40 obtains accurate fingerprint information, the connection between the outer cover 4 and the inner cover 2 can be released, thus preventing others from accidentally drinking the liquid inside the cup and solving the problem of accidental drinking from traditional cups. Furthermore, when the outer cover 4 and inner cover 2 are locked together, the limiting member 3 is not connected to the connecting part 11. At this time, the inner cover 2 and the connecting seat 1 are in a state of relative rotation, making it impossible to release the threaded connection between the connecting seat 1 and the cup by rotating the inner cover 2. Only after the outer cover 4 is flipped open can the limiting member 3 be operated to connect with the connecting part 11. At this point, the connection between the inner cover 2 and the cup can be released by twisting the inner cover 2. The cup's threaded connection allows for refilling or direct drinking of the liquid inside. In general, the cup with this lid uses a fingerprint recognition mechanism 40 to control the connection between the limiting mechanism 41 and the buckle, preventing unauthorized individuals from opening the outer lid 4 and accidentally drinking the liquid through the spout 10. Furthermore, when the outer lid 4 is closed, it conceals the limiting component 3, preventing outsiders from directly unscrewing the inner lid 2 to disengage the threaded connection between the connecting seat 1 and the cup, thus preventing accidental drinking. The cup with this lid, through a double-locking system, effectively prevents the spread of infectious diseases within a group due to misuse of the cup.

[0042] See appendix Figure 5The inner cover 2 has a sliding cavity 20 on the top wall of its bottom cavity, and the limiting member 3 includes a sliding seat 30 and a hand lever 31. The sliding seat 30 is slidably installed in the sliding cavity 20, and one end of the sliding seat 30 forms a limiting protrusion 300 that connects to the connecting part 11. One end of the hand lever 31 is fixedly connected to the sliding seat 30, and the other end of the hand lever 31 passes through the inner cover 2 and is placed on the top of the inner cover 2. Specifically, the inner cover 2 also includes a limiting plate. Two mounting posts are provided on the top wall of the bottom cavity of the inner cover 2, and the limiting plate is provided with two corresponding mounting grooves. The sliding cavity 20 is formed by the connection between the limiting plate and the mounting posts, and the top wall of the sliding cavity 20 is provided with a mounting groove for... The through hole of the handle 31 connects the sliding seat 30 to the sliding cavity 20. The user can engage the handle 31 with the connecting part 11 through the limiting protrusion 300 by passing through the end of the handle 31 through the inner cover 2, thereby connecting the inner cover 2 and the connecting seat 1. In order to facilitate the user's operation of the handle 31, there is also an anti-slip groove structure at the end of the handle 31. The bottom of the outer cover 4 is provided with a relief groove 42 corresponding to the handle 31. When the outer cover 4 closes the top of the inner cover 2, the relief groove 42 closes the handle 31, so that when the outer cover 4 closes the top of the inner cover 2, the bottom of the outer cover 4 and the end of the handle 31 will not interfere with each other, thus improving the structural compactness of the cup lid.

[0043] In order to position the limiting member 3 so that it can be stably in two positions, either engaged with or not engaged with the connecting part 11, this embodiment provides two alternating positioning plates 200 in the sliding cavity 20. The positioning plates 200 are provided with two positioning grooves 201, which are arranged along the sliding direction of the limiting member 3. The sliding seat 30 is provided with positioning protrusions 301 on both sides that can engage with the positioning grooves 201. Specifically, when the positioning protrusions 301 engage with the positioning grooves 201 near the connecting part 11, the limiting member 3 is in the position engaged with the connecting part 11. At this time, the connecting seat 1 can rotate together with the inner cover 2. Conversely, when the positioning protrusions 301 engage with the positioning grooves 201 away from the connecting part 11, the limiting member 3 is in the position not engaged with the connecting part 11. At this time, the connecting seat 1 cannot rotate together with the inner cover 2.

[0044] To facilitate the user's sliding of the limiting member 3, two symmetrical openings 302 are provided on the sliding seat 30, and the openings 302 are located close to the limiting protrusion 300. The openings 302 extend along the sliding direction of the limiting member 3. The openings 302 make the positioning protrusion 301 have a certain elasticity, and the positioning protrusion 301 is a semi-cylindrical structure. The positioning groove 201 is a semi-cylindrical groove, so that the user can switch the positioning protrusion 301 between the two positioning grooves 201 by simply sliding the hand handle 31.

[0045] See appendix Figure 4The connecting part 11 consists of multiple toothed grooves 110 formed on the outer wall of the suction tube 10. Specifically, the multiple toothed grooves 110 are evenly spaced along the circumference of the suction tube 10. The limiting protrusion 300 is a frustoconical structure with rounded edges at the front end, so that the limiting protrusion 300 can be inserted into the toothed grooves 110 for locking. The design of multiple toothed grooves 110 makes it possible to insert the limiting protrusion 300 into the toothed grooves 110 for locking regardless of the angle to which the inner cover 2 is rotated.

[0046] See appendix Figure 4-5 The outer wall of the connecting seat 1 is provided with a limiting annular groove 13, and the inner wall of the bottom cavity of the inner cover 2 is provided with multiple limiting buckles 21. When the inner cover 2 closes the connecting seat 1, the limiting buckles 21 are placed in the limiting annular groove 13, and the axial displacement of the inner cover 2 is limited by the limiting buckles 21 and the limiting annular groove 13. Specifically, by connecting the limiting buckles 21 and the limiting annular groove 13, the axial displacement between the inner cover 2 and the connecting seat 1 can be limited, while allowing the inner cover 2 to rotate relative to the connecting seat 1, thereby improving the connection stability between the inner cover 2 and the connecting seat 1.

[0047] To facilitate the connection between the inner cover 2 and the connecting seat 1, the outer wall of the connecting seat 1 is provided with multiple guide grooves 14 corresponding to the multiple limiting buckles 21. The guide grooves 14 extend along the axial direction of the connecting seat 1, and the guide grooves 14 are not connected to the limiting ring grooves 13. Specifically, the distance between the guide grooves 14 and the limiting ring grooves 13 is small, and the side wall of the guide groove 14 near the limiting ring grooves 13 is an inclined wall, so that the limiting buckles 21 can quickly enter the limiting ring grooves 13 through the guide grooves 14.

[0048] See appendix Figure 1 Other embodiments also provide a cup, including the cup lid and cup body 5 described above, with the cup lid connector 1 threadedly connected to the cup body 5.

[0049] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
