[0087] The fastener 122 is hinged on the hinge shaft 1211 through the notched ring column 1223.

[0088] The bending part of the fastener 122 is placed between the two shoulder steps 1132 of the T-shaped notch of the second cover body 112 through the rotating shaft boss 1222. Each rotating shaft boss 1222 is a cylindrical shape with a diameter equal to the above-mentioned gap D2, and is rotatably stuck between the two positioning bosses of the positioning part 1123 of the second cover body 112.

[0089] That is, the L-shaped fastener 122: corresponds to the side wall through hole 100d one by one, is hinged at the side wall through hole 100d with the bending part, is hinged at the outer edge of the central plate 121 with the end of the radially inner branch arm, and the radially outer branch arm is configured as a wedge-shaped hook 1221.

[0090] The inclined surface of the wedge-shaped hook 1221 faces radially outward and the cup mouth 810.

[0091] Wedge-shaped catch 1221: When the cam 142 does not contact the center plate 121, it protrudes from the side wall through-hole 100d, so that it can automatically snap into the inner wall groove 810a of the cup mouth 810; when the cam 142 rotates and lifts the center plate 121, it retracts into the side wall through-hole 100d to unlock the cup lid 100 from the cup mouth 810.

[0092] The verification unit 130 is a fingerprint lock configured as an embedded computer system, including components such as a circuit main board 131, a magnetic charging base 132, a fingerprint module 133, and a charging battery.

[0093] Circuit main board 131: Assembled with conventional components such as a computing chip, a storage chip, a charging circuit, and a data connector, powered by a charging battery, and connected to the charging battery, the magnetic charging base 132, the fingerprint module 133, and the micro motor 142 through cables respectively.

[0094] The circuit main board 131 is provided with edge through-holes for being installed on the top of the protruding part 1124 of the second cover 112 by screws.

[0095] Magnetic charging base 132: Assembled on the first cover 111, used for magnetically attracting an external charging connector to charge the charging battery, including one or more permanent magnets and a pair of charging pole columns 1321. The top surface of the charging pole column 1321 is exposed outside the bottom surface of the strip-shaped groove 111b.

[0096] Charging battery: Powers the fingerprint module 133, the circuit main board 131, and the micro motor 141, and can be charged by connecting to an external power supply through the charging base 132.

[0097] Fingerprint module 133: Embedded in the top surface of the first cover 111, electrically connected to the circuit main board 131, used for receiving fingerprint input operations and outputting fingerprint data to the circuit main board 131.

[0098] The storage chip of the circuit main board 131 pre-stores the fingerprint data of the owner of the beverage cup. When the circuit main board 131 compares the input fingerprint and the pre-stored fingerprint successfully, it outputs an unlocking instruction and controls the micro motor 141 to unlock.

[0099] In the normal state, the tip of the cam 142 points radially outward and does not contact the center plate 121; the center plate 121 is pressed by the compression spring 123, the sealing convex column 1213 seals the plastic two-way joint 115, the two rectangular prisms 1133 of the third cover 113 abut against the lower part of the hinge shafts 1211 on both sides, and the wedge-shaped catch 1221 protrudes from the side wall through-hole 100d.

[0100] During use, the bottom end of the safety cup lid 100 is inserted into the cup mouth 810, and the inner wall of the cup mouth 810 squeezes the wedge-shaped catch 1211 into the side wall through hole 100d; after the safety cup lid 100 is in place, the wedge-shaped catch 1211 is snapped into the inner wall groove 810a of the cup mouth 810, the plastic sealing ring 114 abuts against the inner wall convex ring 812 of the cup mouth 810, and the barrel wall of the first lid body 111 shields the hidden part 811 of the cup mouth 810, thus locking onto the cup mouth 810; before opening the cup lid, the fingerprint module 133 accepts a fingerprint input operation. After the verification unit 130 acquires and verifies the user's fingerprint information, it issues an unlocking instruction and controls the micro motor to rotate. As a result, the cam rotates 90 degrees to lift the center plate 121, and the center plate 121 drives the three buckle members 122, causing the wedge-shaped catch 1221 to retract into the side wall through hole 100d, thus unlocking; at the same time, the sealing convex column 1213 disengages from the plastic two-way joint 115, allowing the inside of the beverage cup to communicate with the atmosphere through the second cavity 110b to eliminate the pressure difference.
