[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0022] This embodiment relates to a fingerprint-unlocked water cup, such as... Figure 1-4 As shown, the cup includes a cup body 1, a straw assembly, a cup lid, a fingerprint lock, and a magnetic limiting assembly. The straw assembly extends into the cup body 1 and is threadedly connected to the cup body 1. The cup lid includes a lower cup lid shell 8, a middle cup lid shell 10, and an upper cup lid shell 20. The lower cup lid shell 8 is rotatably connected to the straw assembly. The middle cup lid shell 10 is installed inside the upper cup lid shell 20, and a locking element is provided between the middle cup lid shell 10 and the lower cup lid shell 8. The fingerprint lock is installed on the upper cup lid shell 20, and a fingerprint control module 15 is provided inside the fingerprint lock. The fingerprint control module 15 controls the opening and closing of the locking element. The magnetic limiting assembly is installed on the middle cup lid shell 10 and the lower cup lid shell 8, and the lower end of the magnetic limiting assembly extends into the straw assembly. The magnetic limiting assembly is used to limit the straw assembly.

[0023] Before using the water cup, users can register their fingerprints through the fingerprint lock so that they can unlock it later using their fingerprints.

[0024] When the cup lid is closed, the locking component is in the locked state, and the lower shell 8 and the middle shell 10 of the cup lid are locked together. The lower end of the magnetic limiting component is not located inside the straw assembly and cannot limit the straw assembly. If the lower shell 8 or the upper shell 20 of the cup lid is rotated at this time, the lower shell 8 will only rotate freely on the cup body 1 and cannot open the cup lid. This can effectively prevent outsiders from opening the cup lid, greatly improve the safety protection performance of the water cup, prevent pranks on the water cup when the user is not paying attention, and eliminate the risk of taking the wrong water cup or using the wrong water cup when there are multiple identical water cups.

[0025] To open the cup lid, the user can press the fingerprint lock with their finger. The fingerprint control module 15 in the fingerprint lock can recognize the fingerprint left by the user as a registered fingerprint. The fingerprint control module 15 will activate the locking mechanism, causing the locking mechanism to be opened. At this time, moving the upper shell 20 of the cup lid can separate the middle shell 10 of the cup lid from the lower shell 8 of the cup lid. The user can then use the straw assembly to suck up the liquid in the cup 1. After the inner shell 10 of the cup lid separates from the lower shell 8 of the cup lid, the lower end of the magnetic limiting component will enter the straw assembly and limit the straw assembly, so that the lower shell 8 of the cup lid and the straw assembly are limited together. If you want to clean the cup or add liquid to the cup, you can rotate the lower shell 8 of the cup lid to drive the lower end of the magnetic limiting component and the straw assembly to rotate together, so that the lower shell 8 of the cup lid can be unscrewed from the cup body 1.

[0026] Specifically, the straw assembly includes a straw holder 3, a straw 4, and a straw mounting bracket 9. The straw holder 3 is threadedly connected to the cup body 1, and the straw holder 3 is rotatably connected to the lower shell of the cup lid 8. The lower end of the magnetic limiting component extends into the straw holder 3. The upper end of the straw 4 is installed in the straw mounting bracket 9, and the lower end is embedded in the straw holder 3 and extends into the cup body 1. The middle shell of the cup lid 10 seals the upper end of the straw 4 or the upper surface of the straw mounting bracket 9. The straw mounting bracket 9 is installed in the lower shell of the cup lid 8. The straw mounting bracket 9 and the lower shell of the cup lid 8 can be installed by threaded connection, embedding, or snap-fit. When the user drinks water, they can directly draw water from the cup through the straw 4. Alternatively, the straw mounting bracket 9 and the lower shell of the cup lid 8 can also be installed by elastic pressing. The water in the cup is guided through the straw 4 to the gap between the straw mounting bracket 9 and the lower shell of the cup lid 8, and then discharged through the gap.

[0027] Specifically, such as Figure 2-4 As shown, the locking mechanism includes a latch seat 18, a second torsion spring 19, a latch 21, and a nickel-titanium wire 22. The latch seat 18 is mounted on the lower shell 8 of the cup lid, the second torsion spring 19 is mounted on the middle shell 10 of the cup lid, the latch 21 is slidably connected to the middle shell 10 of the cup lid and fixedly connected to the second torsion spring 19, and the latch 21 is engaged with the latch seat 18. The nickel-titanium wire 22 is mounted on the middle shell 10 of the cup lid and fixedly connected to the latch 21. There are five points on the middle shell 10 of the cup lid as fulcrums for the nickel-titanium wire 22 so that the nickel-titanium wire 22 is more stable when it moves. The nickel-titanium wire 22 is electrically connected to the fingerprint control module 15.

[0028] Specifically, such as Figure 2 As shown, the fingerprint lock also includes a mounting shell 14 and a lens 16. The mounting shell 14 is fixed to the side of the upper shell 20 of the cup lid, and the lens 16 is sealed and installed on the mounting shell 14 and in contact with the fingerprint control module 15. The lens 16 is used to acquire fingerprints.

[0029] Specifically, such as Figure 2 As shown, the magnetic limiting assembly includes a rotating stop 5, a first strong magnet 6, a first torsion spring 7, and a second strong magnet 23, which are fixed together in sequence. The rotating stop 5, the first strong magnet 6, and the first torsion spring 7 are fixed together in sequence. The first torsion spring 7 is fixed inside the lower shell 8 of the cup lid, and the second strong magnet 23 is fixed on the middle shell 10 of the cup lid. The first strong magnet 6 and the second strong magnet 23 attract each other. The straw bracket 3 has a groove 31 for the rotating stop 5 to enter. When the first strong magnet 6 and the second strong magnet 23 attract each other, the first torsion spring 7 is in a compressed state. When the middle shell 10 of the cup lid is separated from the lower shell 8 of the cup lid, the first strong magnet 6 and the second strong magnet no longer attract each other. The first torsion spring 7, which has elastic potential energy, will push the rotating stop 5 into the groove 31, so that the middle shell 10 of the cup lid and the lower shell 8 of the cup lid are limited together.

[0030] like Figure 2As shown, a storage battery 17 is installed inside the upper shell 20 of the cup lid. The fingerprint lock and the nickel-titanium wire 22 are both electrically connected to the storage battery 17. The storage battery 17 provides power to the fingerprint lock and the nickel-titanium wire 22. The voltage of the power supply is 12V.

[0031] Furthermore, a charging port 12 is provided on one side of the upper shell 20 of the cup lid. The charging port 12 is preferably a TPC charging port. The battery 17 is electrically connected to the charging port 12, and a waterproof plug 13 is sealed and embedded in the charging port 12. When not charging, the waterproof plug 13 can be used to block the charging port 12 to prevent water from entering the charging port 12.

[0032] like Figure 2 and 4 As shown, the lower shell 8 of the cup lid is hinged to the upper shell 20 of the cup lid, and a handle 11 is installed at the hinge point between the lower shell 8 of the cup lid and the upper shell 20 of the cup lid. The handle 11 makes it convenient for users to carry the water cup.

[0033] like Figure 1-3 As shown, an anti-slip pad 2 is fitted onto the bottom of the cup body 1. The surface of the anti-slip pad 2 is flush with the surface of the cup body 1. The use of the anti-slip pad 2 increases the friction at the bottom of the cup body 1, preventing the cup from sliding when placed on the table.

[0034] Preferably, the water cup is a thermos cup, which is convenient for keeping the liquid inside the cup body 1 warm.

[0035] The working principle is as follows: When a user wants to open the cup lid, they press the fingerprint lock lens 16 with their fingerprint-registered finger. The lens 16 acquires the fingerprint, and the fingerprint control module 15, after recognizing the user's fingerprint, sends an electrical signal to the nickel-titanium wire 22. Upon receiving the electrical signal, the nickel-titanium wire 22 contracts to pull the latch 21. The latch 21 moves into the inner shell 10 of the cup lid and compresses the second torsion spring 19, separating the latch 21 from the latch seat 18. At this time, flipping up the upper shell 20 of the cup lid separates the inner shell 10 of the cup lid from the lower shell 8 of the cup lid. Figure 3 As shown, the user can use the straw 4 to draw liquid from the cup 1. It should be noted that the fingerprint lock is in a power-off state when there is no fingerprint touch, and the nickel-titanium wire 22 returns to its original state, that is, the stretched state.

[0036] After the inner shell 10 of the cup lid separates from the lower shell 8 of the cup lid, the first strong magnet 6 no longer attracts the second strong magnet 23, and the first strong magnet 6 and the second strong magnet no longer attract each other. The first torsion spring 7 with elastic potential energy will spring the stop 5 into the groove 31, so that the straw support 3 and the lower shell 8 of the cup lid are limited together. If the user wants to unscrew the straw support 3 from the cup body 1, he only needs to rotate the lower shell 8 of the cup lid to drive the straw support 3 to rotate on the cup body 1, so that the straw support 3 can be unscrewed from the cup body 1.

[0037] When it is necessary to close the upper cover 20 of the cup lid, pressing down on the upper cover 20 will cause the buckle 21 to engage with the buckle seat 18, so that the upper cover 20 and the middle cover 10 of the cup lid cover the lower cover 8 of the cup lid, and the fingerprint lock is in the closed state. At the same time, the second strong magnet 23 can attract the first strong magnet 6 upward, so that the first strong magnet 6 compresses the first torsion spring 7, causing the rotating stop 5 to move out of the groove 31 and no longer limit the straw bracket 3. If an outsider rotates the upper cover 20 or the lower cover 8 of the cup lid afterward, the lower cover 8 of the cup lid will only spin on the straw bracket 3 and will not be able to unscrew the straw bracket 3 from the cup body 1, thus enhancing the safety protection performance of the water cup.

[0038] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
