[0007] As described above, in a smart fingerprint unlocking thermos, the slide plate has a through first groove that extends along the sliding direction of the slide plate. A slider is slidably disposed within the first groove, and the slider is fixedly connected to the connecting block.

[0008] As described above, a smart fingerprint unlocking thermos bottle has a lid including an upper lid and a bottom lid. The bottom of the upper lid is provided with two positioning blocks. One of the positioning blocks near the slide plate has a groove. The slide plate is slidably disposed in the groove.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1 to 7As shown, this invention proposes a smart fingerprint-unlocking thermos, including a bottle body 1. A slot 11 is formed on the inner wall of the bottle body 1. A bottle cap 2 is fitted onto one end of the bottle body 1. A pressing mechanism 24 is provided inside the bottle cap 2. The pressing mechanism 24 includes a spring 243. The two ends of the spring 243 respectively abut against a first pressing block 241 and a second pressing block 242. A locking block 2411 is provided on one side of both the first pressing block 241 and the second pressing block 242. The locking block 2411 engages with the slot 11. A fingerprint sensor 21 is provided on the surface of the bottle cap 2. A locking mechanism 23 is provided inside the bottle cap 2. The locking mechanism 23 includes a connecting block 232. One side of the connecting block 232... A sliding plate 233 is connected to the side, and a swing mechanism is connected to one side of the sliding plate 233. The swing mechanism is used to drive the sliding plate 233 to slide linearly. A first locking block 2413 is provided on one side of the first pressing block 241. A first limiting groove 2414 is opened on the bottom side of the first locking block 2413. A second locking block 2421 is provided on one side of the second pressing block 242. A second limiting groove 2422 is opened on the top side of the second locking block 2421. The first limiting groove 2414 and the second limiting groove 2422 together form a locking groove. One side of the sliding plate 233 can extend into or out of the locking groove. The fingerprint sensor 21 is electrically connected to the swing mechanism. In use, the user places their finger on the fingerprint sensor 21 on the surface of the bottle cap 2 for recognition. The fingerprint sensor 21 is electrically connected to the swing mechanism. After successful recognition, the swing mechanism is controlled to move. The swing mechanism drives the slide plate 233 to slide in a straight line, causing one side of the slide plate 233 to disengage from the locking groove formed by the first limiting groove 2414 and the second limiting groove 2422. At this time, pressing the first pressing block 241 and the second pressing block 242 brings them closer together, causing the locking block 2411 on them to disengage from the locking groove 11 on the inner wall of the bottle body 1, thereby unlocking the bottle cap 2. When the first pressing block 241 and the second pressing block 242 are released, the spring 243 will push them to return to their original positions. Conversely, when the slide plate 233 is driven by the swing mechanism to re-enter the locking groove, it restricts the relative movement of the first pressing block 241 and the second pressing block 242, keeping the locking block 2411 in the locking groove 11, thus completing the locking. By linking the fingerprint sensor 21 with the swing mechanism, the slide plate 233 and the pressing mechanism 24, an automatic unlocking function based on biometrics is realized, which is convenient and secure, without the need for a key or password.

[0027] Optionally, in some embodiments, the fingerprint sensor 21 is mounted on the top surface of the bottle cap 2, and the sensing area of ​​the fingerprint sensor 21 is lower than the outer surface of the bottle cap 2. When a user performs fingerprint recognition, their finger naturally touches the top surface of the bottle cap 2, covering the sensing area of ​​the fingerprint sensor 21 located in the recessed position, thereby completing biometric data collection and verification. By setting the sensing area of ​​the fingerprint sensor 21 to be lower than the outer surface of the bottle cap 2, friction and scratches during daily carrying or placement are effectively avoided.

[0028] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, a second sliding groove 2332 is provided on one side of the sliding plate 233. The swing mechanism includes a motor 231, which is electrically connected to the fingerprint sensor 21. A rotating block 2311 is connected to the power output end of the motor 231. A swing block 2312 is provided on one side of the rotating block 2311, and the swing block 2312 slides within the second sliding groove 2332. When the fingerprint sensor 21 successfully recognizes the fingerprint, it controls the motor 231 to start. The power output end of the motor 231 drives the rotating block 2311 to rotate, and the swing block 2312 on one side of the rotating block 2311 moves accordingly and slides within the second sliding groove 2332. This converts the rotational motion of the rotating block 2311 into the linear sliding motion of the sliding plate 233, enabling the sliding plate 233 to extend into or disengage from the locking groove. The rotational output of the motor 231 is converted into the linear motion required by the sliding plate 233, resulting in a compact structure and reliable transmission.

[0029] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the slide plate 233 has a through-type first slide groove 2331, which extends along the sliding direction of the slide plate 233. A slider 2321 is slidably disposed within the first slide groove 2331, and the slider 2321 is fixedly connected to the connecting block 232. The bottle cap 2 includes an upper cap 22 and a bottom cap 25. The bottom of the upper cap 22 has two positioning blocks 222, one of which, near the slide plate 233, has a slide groove 223. The slide plate 233 is slidably disposed within the slide groove 223, and the cross-sectional shape of the slide groove 223 matches the cross-sectional shape of one end of the slide plate 233. When the slide plate 233 slides linearly under the drive of the swing mechanism, on the one hand, the connecting block 232 moves through the cooperation of the first slide groove 2331 and the slider 2321; on the other hand, it moves smoothly under the guidance and constraint of the slide groove 223, ensuring accurate and reliable transmission. This allows the skateboard 233 to effectively transmit linear motion within a limited space, effectively preventing the skateboard 233 from deflecting or wobbling during movement.

[0030] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the distance between the two positioning blocks 222 is equal to the outer diameter of the spring 243, and the spring 243 is sandwiched between the two positioning blocks 222. This arrangement ensures that the outer periphery of the spring 243 is limited by the two positioning blocks 222 during axial compression or reset, preventing the spring 243 from lateral displacement or twisting, thereby ensuring that its elastic force acts stably on the relevant components of the pressing mechanism 24.

[0031] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the bottle cap 2 also includes a main control chip and a power module. The main control chip is electrically connected to the fingerprint sensor 21, the motor 231, and the power module, respectively, and is used to control the start and stop of the motor 231 according to the recognition result of the fingerprint sensor 21. When a user's finger touches the fingerprint sensor 21, the fingerprint sensor 21 collects biometric information and transmits it to the main control chip. After verification, if the recognition is successful, the main control chip controls the motor 231 to start, driving the swing mechanism to unlock the device. If the recognition fails or there is no operation, the main control chip keeps the motor 231 in a stopped state, and the power module continuously provides power to the main control chip and the fingerprint sensor 21.

[0032] Furthermore, as a preferred embodiment of the invention and not a limitation thereof, the side wall of the bottom cover 25 has a through hole 251 through which the locking block 2411 slides, and the bottom of the locking block 2411 has a chamfer. When the pressing mechanism 24 is activated to move the locking block 2411 inward to disengage from the slot 11 of the bottle body 1, the locking block 2411 slides along the through hole 251, and the chamfer at its bottom plays a guiding role in passing through the edge of the through hole 251 or engaging with the bottle body 1, reducing movement resistance.

[0033] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the bottom cover 25 is provided with a motor base 252, and the motor 231 is fixed inside the motor base 252. The inner wall of the motor base 252 is provided with a protrusion, and the side wall of the motor housing 231 is provided with a notch, which mates with the protrusion of the motor base 252. During assembly, the motor 231 is placed into the motor base 252, the notch is aligned, and the protrusion is engaged, thereby achieving the positioning and limiting of the motor 231 in the circumferential and axial directions, effectively preventing the motor 231 from shifting or loosening due to vibration or torque during operation.

[0034] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the upper cover 22 is provided with a through groove 221, the position of which corresponds to the first pressing block 241 and the second pressing block 242. The through groove 221 is used for the user's fingers to press the first pressing block 241 and the second pressing block 242. When manual operation is required, the user's fingers can directly contact and press the first pressing block 241 and the second pressing block 242 through the through groove 221, causing them to overcome the elastic force of the spring 243 and move closer to each other, thereby driving the locking block 2411 to disengage from the locking groove 11 of the bottle body 1, and releasing the locking between the bottle cap 2 and the bottle body 1.

[0035] Example 1: This invention discloses a smart fingerprint-unlocking thermos bottle, comprising a bottle body 1 with a slot 11 on its inner wall. A cap 2 is fitted onto one end of the bottle body 1. The cap 2 contains a pressing mechanism 24, which includes a spring 243. The two ends of the spring 243 abut against a first pressing block 241 and a second pressing block 242, respectively. Each of the first and second pressing blocks 241 and 242 has a locking block 2411 on one side, which engages with the slot 11. A fingerprint sensor 21 is mounted on the top surface of the cap 2, with its sensing area lower than the outer surface of the cap 2. When a user performs fingerprint recognition, their finger naturally contacts the top surface of the cap 2, covering the sensing area of ​​the fingerprint sensor 21 located in the recessed position, thereby completing biometric data collection and verification. By setting the sensing area of ​​the fingerprint sensor 21 to be lower than the outer surface of the bottle cap 2, friction and scratches during daily carrying or placement are effectively avoided. The bottle cap 2 is provided with a locking mechanism 23, which includes a connecting block 232. A sliding plate 233 is slidably connected to one side of the connecting block 232. A swing mechanism is driven to one side of the sliding plate 233. The swing mechanism is used to drive the sliding plate 233 to slide linearly. A first locking block 2413 is provided on one side of the first pressing block 241. A first limiting groove 2414 is opened on the bottom side of the first locking block 2413. A second locking block 2421 is provided on one side of the second pressing block 242. A second limiting groove 2422 is opened on the top side of the second locking block 2421. The first limiting groove 2414 and the second limiting groove 2422 together form a locking groove. One side of the sliding plate 233 can extend into or out of the locking groove. The fingerprint sensor 21 is electrically connected to the swing mechanism. In use, the user places their finger on the fingerprint sensor 21 on the surface of the bottle cap 2 for recognition. The fingerprint sensor 21 is electrically connected to the swing mechanism. After successful recognition, the swing mechanism is controlled to move. The swing mechanism drives the slide plate 233 to slide in a straight line, causing one side of the slide plate 233 to disengage from the locking groove formed by the first limiting groove 2414 and the second limiting groove 2422. At this time, pressing the first pressing block 241 and the second pressing block 242 brings them closer together, causing the locking block 2411 on them to disengage from the locking groove 11 on the inner wall of the bottle body 1, thereby unlocking the bottle cap 2. When the first pressing block 241 and the second pressing block 242 are released, the spring 243 will push them to return to their original positions. Conversely, when the slide plate 233 is driven by the swing mechanism to re-enter the locking groove, it restricts the relative movement of the first pressing block 241 and the second pressing block 242, keeping the locking block 2411 in the locking groove 11, thus completing the locking. By linking the fingerprint sensor 21 with the swing mechanism, the slide plate 233 and the pressing mechanism 24, an automatic unlocking function based on biometrics is realized, which is convenient and secure, without the need for a key or password.

[0036] The bottle cap 2 also houses a main control chip and a power module. The main control chip is electrically connected to the fingerprint sensor 21, the motor 231, and the power module, respectively, and is used to control the start and stop of the motor 231 based on the recognition result of the fingerprint sensor 21. When a user's finger touches the fingerprint sensor 21, the fingerprint sensor 21 collects biometric information and transmits it to the main control chip. After verification, if the recognition is successful, the main control chip controls the motor 231 to start, driving the swing mechanism to unlock the device. If the recognition fails or there is no operation, the main control chip keeps the motor 231 in a stopped state, and the power module continuously provides power to the main control chip and the fingerprint sensor 21.

[0037] The slide plate 233 has a second slide groove 2332 on one side. The swing mechanism includes a motor 231, which is electrically connected to the fingerprint sensor 21. The power output end of the motor 231 is connected to a rotating block 2311. A swing block 2312 is provided on one side of the rotating block 2311, and the swing block 2312 is slidably engaged in the second slide groove 2332. When the fingerprint sensor 21 successfully recognizes the fingerprint, it controls the motor 231 to start. The power output end of the motor 231 drives the rotating block 2311 to rotate. The swing block 2312 on one side of the rotating block 2311 moves accordingly and slides in the second slide groove 2332, thereby converting the rotational motion of the rotating block 2311 into the linear sliding of the slide plate 233. This allows the slide plate 233 to extend into or disengage from the locking groove. The rotational output of the motor 231 is converted into the linear motion required by the slide plate 233, resulting in a compact structure and reliable transmission.

[0038] The slide plate 233 has a through-type first groove 2331, which extends along the sliding direction of the slide plate 233. A slider 2321 is slidably disposed within the first groove 2331, and the slider 2321 is fixedly connected to the connecting block 232. The bottle cap 2 includes an upper cap 22 and a bottom cap 25. The bottom of the upper cap 22 has two positioning blocks 222, one of which, near the slide plate 233, has a groove 223. The slide plate 233 is slidably disposed within the groove 223, and the cross-sectional shape of the groove 223 matches the cross-sectional shape of one end of the slide plate 233. When the slide plate 233 slides linearly under the drive of the swing mechanism, on the one hand, the first groove 2331 and the slider 2321 cooperate to drive the connecting block 232 to move; on the other hand, it moves smoothly under the guidance and constraint of the groove 223, ensuring accurate and reliable transmission. This allows the slide plate 233 to effectively transmit linear motion within a limited space and effectively prevents the slide plate 233 from deflecting or wobbling during movement.

[0039] The side wall of the bottom cover 25 has a through hole 251 through which the locking block 2411 slides. The bottom of the locking block 2411 has a chamfer. When the pressing mechanism 24 moves the locking block 2411 inward to disengage from the slot 11 of the bottle body 1, the locking block 2411 slides along the through hole 251. The chamfer at its bottom plays a guiding role in passing through the edge of the through hole 251 or engaging with the bottle body 1, reducing movement resistance.

[0040] The distance between the two positioning blocks 222 is equal to the outer diameter of the spring 243, and the spring 243 is sandwiched between the two positioning blocks 222. This arrangement ensures that the outer periphery of the spring 243 is limited by the two positioning blocks 222 during axial compression or reset, preventing the spring 243 from shifting laterally or twisting, thereby ensuring that its elastic force acts stably on the relevant components of the pressing mechanism 24.

[0041] The bottom cover 25 is equipped with a motor base 252, and the motor 231 is fixed inside the motor base 252. The inner wall of the motor base 252 has a protrusion, and the side wall of the motor housing 231 has a notch that mates with the protrusion of the motor base 252. During assembly, the motor 231 is placed into the motor base 252, the notch is aligned, and the protrusion is engaged, thereby achieving the positioning and limiting of the motor 231 in the circumferential and axial directions, effectively preventing the motor 231 from shifting or loosening due to vibration or torque during operation.

[0042] The top cover 22 has a through groove 221, which corresponds to the position of the first pressing block 241 and the second pressing block 242. The through groove 221 is used for the user's fingers to press the first pressing block 241 and the second pressing block 242. When manual operation is required, the user's fingers can directly contact and press the first pressing block 241 and the second pressing block 242 through the through groove 221, causing them to overcome the elastic force of the spring 243 and move closer to each other, thereby driving the locking block 2411 to disengage from the locking groove 11 of the bottle body 1 and releasing the locking between the bottle cap 2 and the bottle body 1.

[0043] Specifically, the working principle of this invention is as follows:

[0044] The user places their finger on the fingerprint sensor 21 on the top surface of the bottle cap 2 for recognition. Since the sensing area of ​​the fingerprint sensor 21 is lower than the outer surface of the bottle cap 2, it can effectively prevent scratches and wear. After the recognition signal is processed by the main control chip, if the verification is successful, the motor 231 is started. The motor 231 drives the rotating block 2311 to rotate through its power output end. The swing block 2312 on the rotating block 2311 slides in the second slide groove 2332 of the slide plate 233, thereby converting the rotational motion into the linear sliding of the slide plate 233, so that one side of the slide plate 233 disengages from the locking groove formed by the first limiting groove 2414 and the second limiting groove 2422.

[0045] When the slide plate 233 exits the locking groove, the limiting of the first pressing block 241 and the second pressing block 242 is released; at this time, the user manually presses the first pressing block 241 and the second pressing block 242 through the through groove 221 on the top cover 22, so that they overcome the elastic force of the spring 243 and move closer to each other, causing the locking block 2411 to move inward along the through hole 251 on the side wall of the bottom cover 25. The chamfer at the bottom of the locking block 2411 guides it to smoothly disengage from the locking groove 11 on the inner wall of the bottle body 1, thereby unlocking the bottle cap 2.

[0046] After releasing the first pressing block 241 and the second pressing block 242, the spring 243, clamped between the two positioning blocks 222, pushes them back to their original positions, and the locking block 2411 extends again. When the user finishes using the thermos and wants to relock it, the fingerprint sensor 21 can be triggered again. After receiving the locking command, the main control chip controls the motor 231 to run, driving the rotating block 2311 to rotate in the opposite direction. This causes the swing block 2312 to push the sliding plate 233 to move linearly along the guide path of the slider 2321 in the slide groove 223 and the first slide groove 2331, and re-enter the locking groove formed by the first limiting groove 2414 and the second limiting groove 2422. At this time, the sliding plate 233 restricts the first pressing block 241 and the second pressing block 242 from getting close to each other. Even if pressed by external force, the locking block 2411 cannot disengage from the locking groove 11, thus achieving reliable automatic locking. Throughout the process, the spring 243 is stably clamped between the two positioning blocks 222 to prevent displacement and ensure long-term stable operation of the mechanism.
