[0027] Example:

[0028] Cup lids and water cups, such as Figure 1-Figure 6As shown, it includes a bottom cover 1, a flip cover 2 and a torsion spring arranged at the rotation connection between the bottom cover 1 and the flip cover 2, and the torsion spring provides power for the rotation after opening the flip cover 2, wherein the bottom cover 1 includes an outer cover 3 and an inner cover 4 rotatably connected to the outer cover 3, the inner cover 4 is provided with an internal thread for connecting with the cup body 18 to realize the connection between the cup cover and the water cup, a positioning assembly is provided on the outer cover 3, and a hole is also provided on the outer cover 3 for the positioning assembly to pass through and abut against the inner cover 4, and a pressing piece 5 for pressing the positioning assembly is provided on the flip cover 2, so that when the flip cover 2 is closed, the pressing piece 5 presses the positioning assembly to separate from the inner cover 4, and releases the fixed connection between the outer cover 3 and the inner cover 4, so that when the flip cover 2 is closed, the inner cover 4 and the outer cover 3 are in a rotating state, so when the cup cover is directly rotated, the inner cover 4 does not move, and the outer cover 3 can rotate in any direction, but the cup cover cannot be opened, thereby ensuring the safety of the liquid in the water cup and improving the personal safety of the user.

[0029] At the same time Figure 2-Figure 4 As shown, the flip cover 2 is set to a split structure, including an upper flip cover 2 and an equipment compartment support plate, so that a cavity is formed in the internal design of the flip cover 2, a lock tongue slider 6 is slidably arranged in the cavity, a lock buckle 7 for engaging with the lock tongue slider 6 is fixedly arranged on the bottom cover 1, a slideway for the lock tongue slider 6 to slide and a hole for the lock buckle 7 to be embedded in the cavity are provided on the equipment compartment support plate, so that when the flip cover 2 is closed, the lock buckle 7 is embedded in the cavity through the hole to be connected with the lock tongue slider 6, wherein a driving component is provided at one end of the lock tongue slider 6 away from the lock buckle 7, and the driving component is connected to a fingerprint recognition module 8, the fingerprint recognition module 8 is fixedly arranged on the flip cover 2, and one side is located on the outer side of the flip cover 2, so that the fingerprint recognition module 8 is activated by fingerprint matching to control the driving component to drive the lock tongue slider 6 from a locked state to an unlocked state, and the identity of the person opening the door is ensured by fingerprint unlocking, thereby ensuring the safety of the liquid in the water cup and improving the personal safety of the user.

[0030] The driving assembly includes an elastic element 29 and a memory metal 10. The two ends of the elastic element 29 are respectively in contact with the lock tongue slider 6 and the flip cover 2. The elastic element 29 provides elastic support force for the lock tongue slider 6, thereby ensuring the connection stability between the lock tongue slider 6 and the lock buckle 7. At the same time, a chamfered structure is provided on the side of the lock buckle 7 close to the flip cover 2, and a chamfered structure is also provided on the side of the lock tongue slider 6 close to the bottom cover 1. Through the cooperation of the two chamfered structures, when the lock buckle 7 is just embedded, the lock buckle 7 pushes the lock tongue slider 6 to form a displacement through the chamfered structure, thereby ensuring that the lock buckle 7 enters smoothly. Then the elastic element 29 pushes the lock tongue slider 6 to reset its position, so that the lock tongue slider 6 and the lock buckle 7 are stably engaged.

[0031] The memory metal 10 is made of high-temperature nickel-titanium wire. The high-temperature nickel-titanium wire has the characteristics of light weight and high strength to ensure the use effect of the memory metal 10, and the deformation temperature of the high-temperature nickel-titanium wire is between 80°C. The recommended liquid temperature of the existing thermos cup is between 60-70°C. This temperature range can not only maintain the heat of the water, but also not easily scald the mouth. The high-temperature nickel-titanium wire has a phase change temperature of >80°C, so the problem of deformation of the high-temperature nickel-titanium wire caused by water temperature can be effectively avoided. At the same time, this application is mainly used for children, and the children's thermos cup requires that the water temperature in the cup shall not exceed 50°C, and the high-temperature nickel-titanium wire is designed to be installed in the upper flip cover 2 equipment compartment, away from high-temperature water, and the working environment is basically at room temperature, which is far lower than the phase change temperature of the high-temperature nickel-titanium wire of 80°C, which can ensure the effectiveness and stability of the high-temperature nickel-titanium wire.

[0032] The memory metal 10 is connected to the lock tongue slider 6, and the memory metal 10 terminal is connected to the fingerprint recognition module 8, so that the fingerprint recognition module 8 supplies power to the memory metal 10. After power is supplied to the memory metal 10, the memory metal 10 heats up and contracts due to resistance heating to reach the phase change temperature, so that the memory metal 10 pulls the lock tongue slider 6 and the lock buckle 7 to separate, and moves from the locked state to the unlocked state.

[0033] A high-temperature nickel-titanium wire mounting column for connecting the memory metal 10 is fixedly provided on the equipment warehouse support plate, so that the two ends of the memory metal 10 are fixedly connected to the inner wall of the cavity, and the middle section of the memory metal 10 is connected to the lock tongue slider 6. In the locked state, the memory metal 10 forms a V-shaped structure. The V-shaped structure increases the deformation space of the memory metal 10, and then also increases the moving stroke of the lock tongue slider 6, thereby ensuring that the lock tongue slider 6 and the lock buckle 7 are stably engaged.

[0034] At the same time Figure 2 , Figure 5 and Figure 6 As shown, the positioning assembly includes a buckle 11 movably arranged on the outer cover 3 and an elastic element 12 that pushes the buckle 11 to abut against the inner cover 4. In the locked state, the end of the buckle 11 away from the elastic element 12 abuts against the pressing member 5, so that the buckle 11 is separated from the inner cover 4, and the outer cover 3 is in a rotating state. When the flip cover 2 is opened, the abutment effect between the pressing member 5 and the buckle 11 causes the elastic element 12 to push the buckle 11 to return to its original position, and then the buckle 11 abuts against the inner cover 4, and the outer cover 3 is in a fixed state. At the same time, a plurality of abutment grooves 13 are provided on one side of the inner cover 4 close to the buckle 11, and the abutment grooves 13 are used to enhance the connection firmness when the buckle 11 abuts against the inner cover 4.

[0035] At the same time Figure 2 and Figure 6As shown, the buckle 11 is rotatably set on the outer cover 3, and the two ends of the buckle 11 on both sides of the rotation point are respectively used to connect with the elastic element 12 and the abutment groove 13. By rotating the buckle 11, when the pressing member 5 abuts against the buckle 11 to push the buckle 11 to move, the relative horizontal movement reduces the displacement resistance, improves the smoothness of the transmission and reduces wear.

[0036] At the same time Figure 2-Figure 4 As shown, the fingerprint recognition module 8 includes a fingerprint control chipset 14 with one side located on the outside of the flip cover 2 and a power supply 15 connected to the fingerprint control chipset 14 through a wire (not shown in the figure), wherein the control principle of the fingerprint control chipset 14 is existing and will not be described in detail here, the power supply 15 adopts a lithium polymer rechargeable battery, so that the power supply 15 can be repeatedly charged, the output end of the fingerprint control chipset 14 is connected to the memory metal 10 through a wire (not shown in the figure), and the fingerprint control chipset 14 is also connected to a magnetic charging seat 20 extending to the outside of the flip cover 2 through a wire (not shown in the figure), and the effect of charging the power supply 15 is achieved through the magnetic charging seat 20.

[0037] An indicator light 19 is provided on the fingerprint control chipset 14, and the indicator light 19 is directly integrated and fixedly installed on the fingerprint control chipset 14, thereby reducing production costs, and the indicator light 19 is connected to a light guide fiber 21, through which the light emitted by the indicator light 19 is propagated along the axial direction of the light guide fiber 21, thereby forming a transfer of the light-emitting point, and a through groove is provided on the flip cover 2 for the light guide fiber 21 to be embedded and contacted with the outside world, so that bright light appears at the through groove, and in order to improve the luminous effect of the light guide fiber 21, the scattering point distribution of the optical fiber can be optimized or a more efficient scattering material can be used to improve the scattering efficiency of the light, so that the light guide fiber 21 emits bright light throughout, thereby improving the visual beauty.

[0038] At the same time Figure 2 and Figure 3 As shown, a protrusion 16 embedded in the elastic element 29 is provided at the abutment between the lock tongue slider 6 and the elastic element 29, and a groove 17 is provided at the abutment between the flip cover 2 and the elastic element 29. Through the cooperation of the protrusion 16 and the groove 17, the positioning effect of the position of the elastic element 29 is enhanced to prevent the elastic element 29 from deviation.

[0039] At the same time Figure 1 and Figure 2 As shown, the water cup includes a cup body 18 and a cup cover. The cup body 18 is provided with an external thread for threaded connection with the cup cover. The external thread cooperates with the internal thread of the inner cover 4 to achieve a detachable connection between the cup body 18 and the cup cover.

[0040] The bottom cover 1 is also provided with a silicone nozzle, a straw, and a straw spring, so as to provide the cup body 18 with a straw water absorption function, thereby improving the convenience of use for the user.

[0041] Working principle: when the user wants to drink water or add water to the cup, the fingerprint control chipset 14 is first activated by the finger that records the fingerprint. After the fingerprint control chipset 14 receives the fingerprint and the comparison is correct, the output end will output current to the memory metal 10. After the memory metal 10 is energized, the resistance heats up to the phase change temperature and heats up and contracts, so that the memory metal 10 pulls the lock tongue slider 6 and the lock buckle 7 to separate, and moves from the locked state to the unlocked state. Then the torsion spring pushes the flip cover 2 to form a rotation effect, and then the flip cover 2 is opened, and the flip cover 2 is opened, so that the abutment between the pressing piece 5 and the buckle 11 disappears, and the elastic element 12 pushes the buckle 11 to rotate, so that the buckle 11 is embedded in the abutment groove 13, and then the outer cover 3 and the inner cover 4 form a fixed connection state, and then the user can choose to drink water or add water according to his own needs.
