Description

Technical Field

[0001] This utility model relates to the field of cup technology, and in particular to a self-locking fingerprint lock cup lid. Background Technology

[0002] A fingerprint lock cup lid is a smart cup lid that uses fingerprint recognition technology to unlock and lock the lid. Users need to register their fingerprints in advance, and can quickly unlock and open the lid with just a light touch, combining convenience and security.

[0003] However, traditional fingerprint lock cup lids require users to manually perform two operations: press once to unlock and press again to lock after use. In actual use, users often forget to lock the lid due to negligence. Once the lid is not locked in time, there is a great security risk. Malicious people may take the opportunity to open the lid and put harmful or toxic substances into the cup, and the user is often unaware of it during subsequent use, which can cause serious damage to the user's health.

[0004] Prior art 1 (Chinese patent application number CN202022229336.9, application date 2020-10-09) discloses a fingerprint-unlocked safety water cup, which is equipped with a fingerprint lock device to control the locking and unlocking of the cup body. The lid is fixedly connected to the cup body, and the lower end of the lid is movably connected to the cup body via a hinge with a reverse spring. When not in use, the fingerprint lock device locks the lid to the connecting body. Since the connecting body is fixedly connected to the cup body, when the fingerprint lock is locked, the lid, connecting body, and cup body form a complete unit that cannot be opened arbitrarily. The water cup is equipped with a fingerprint lock, and only the user can unlock it, ensuring the exclusivity of the water cup and solving the technical problem that the cup can be easily opened, thus ensuring the user's drinking water safety.

[0005] Prior art 2 (Chinese patent application number CN201821307629.0, application date 2018-08-14) discloses a fingerprint cup with a fingerprint lock system fixedly connected to the cup lid. The fingerprint unlocking system includes a fingerprint recognition module, a locking device, a PCB board, and a battery. The PCB board is electrically connected to the battery, which powers the components integrated on the PCB board. The fingerprint recognition module is electrically connected to the PCB board and transmits the collected fingerprint information to the CPU integrated on the PCB board for CPU calculation and analysis. The locking device is electrically connected to the PCB board. The PCB board controls the locking device to lock or unlock based on the analysis results of the fingerprint information collected by the fingerprint recognition module. The fingerprint recognition module can verify whether the user's fingerprint matches the original fingerprint information stored internally. If they match, the PCB board controls the locking device to unlock, and the cup lid can be rotated open. If they do not match, the PCB board does not control the locking device to unlock, and the cup lid cannot be rotated open, preventing others from intentionally or unintentionally putting harmful items into the cup and improving the safety of the cup. Utility Model Content

[0006] The purpose of this invention is to provide a self-locking fingerprint lock cup cover to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: it includes a cup lid body, a fingerprint touch panel is provided on the top of the cup lid body, an inner shell is provided inside the cup lid body, and a self-locking component is provided between the inner shell and the cup lid body.

[0008] As a preferred embodiment of the present invention, the self-locking assembly includes a motor disposed on the top of the inner shell, the transmission end of the motor is provided with a rotating seat, and a pull block is provided on one side of the rotating seat.

[0009] As a preferred embodiment of this utility model, the inner shell is provided with a lifting guide rail, a lifting block is slidably arranged in the lifting guide rail, the pull block passes through the top of the lifting block, and a spring is provided between the top side of the lifting block and the inner top surface of the cup lid body.

[0010] As a preferred embodiment of this invention, a locking pin is provided at the bottom of the lifting block, and the locking pin penetrates the inner shell.

[0011] As a preferred embodiment of this utility model, the bottom of the cup lid body is connected to the cup body, the top of the cup body is provided with a fixing seat, the cup lid body is threadedly connected to the fixing seat, and the fixing seat is provided with a locking hole corresponding to the locking pin.

[0012] In a preferred embodiment of this invention, the fingerprint touch panel is connected to the motor control.

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] 1. This utility model features a self-locking component. When the user attaches the lid to the fixed base on top of the cup body and tightens it, the locking pin contacts the fixed base and is first subjected to pressure. This pressure causes the lifting block to compress the spring. When the locking pin moves to the lock hole, the spring's restoring force pushes the lifting block down, causing the locking pin to accurately insert into the lock hole, thus automatically locking the lid to the cup body. This improves convenience and safety, making it especially suitable for people with special needs. It effectively avoids safety hazards caused by forgetting to lock the lid. Secondly, in terms of unlocking, the fingerprint touch panel is connected to the motor control. The motor will only start when the fingerprint is successfully recognized. The motor drives the rotating base and the pull block to rotate. The pull block then drives the lifting block to rise along the lifting guide rail, causing the locking pin to exit the lock hole, thereby unlocking the lid. After the user opens the lid, the fingerprint touch panel will control the motor to rotate in the opposite direction, resetting the relevant components. When the lid and cup body are tightened again, the lid will automatically lock, requiring no additional user operation and thus preventing the situation of forgetting to lock the lid.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] like Figures 1-3As shown, the self-locking fingerprint lock cup lid proposed in this utility model includes a cup lid body 1, a fingerprint touch panel 2 is provided on the top of the cup lid body 1, the fingerprint touch panel 2 is used to receive the user's fingerprint information for identity recognition, and the cup lid body 1 can only be unlocked after successful recognition, an inner shell 3 is provided inside the cup lid body 1, the inner shell 3 provides the installation base for the self-locking component 4, and the self-locking component 4 is provided between the inner shell 3 and the cup lid body 1.

[0021] The self-locking assembly 4 includes a motor 41 located on the top of the inner shell 3. The motor 41 rotates forward and backward according to the control signal of the fingerprint touch panel 2, driving the rotating base 42 to rotate. The transmission end of the motor 41 is provided with the rotating base 42. The rotating base 42 transmits the rotational motion of the motor 41 to the pull block 43, driving the pull block 43 to rotate. The pull block 43 is provided on one side of the rotating base 42. When the pull block 43 rotates, it applies force to the lifting block 44, causing the lifting block 44 to move, thereby controlling the locking needle 46 to enter and exit the lock hole 7.

[0022] The inner shell 3 is provided with a lifting guide rail 45, and a lifting block 44 is slidably arranged inside the lifting guide rail 45. The lifting guide rail 45 provides guidance for the lifting block 44 to ensure the stability of the lifting block 44 when it moves. The pull block 43 passes through the top of the lifting block 44. A spring 47 is provided between the top side of the lifting block 44 and the inner top surface of the cup lid body 1. The spring 47 provides a restoring force for the lifting block 44 and the locking pin 46, pushing the locking pin 46 to insert into the locking hole 7.

[0023] The bottom of the lifting block 44 is provided with a locking pin 46, which penetrates the inner shell 3. The locking pin 46 locks and unlocks the cup lid body 1 by moving in and out of the locking hole 7.

[0024] The bottom of the cup lid body 1 is connected to the cup body 5, and the top of the cup body 5 is provided with a fixing seat 6. The cup lid body 1 and the fixing seat 6 are threadedly connected. The fixing seat 6 has a locking hole 7 corresponding to the locking pin 46. The fixing seat 6 and the cup lid body 1 are threadedly connected. The locking hole 7 corresponds to the locking pin 46. When the cup lid body 1 is tightened, it provides an insertion position for the locking pin 46 to achieve automatic locking. The fingerprint touch panel 2 is connected to the motor 41 for control.

[0025] Working principle: When the user needs to open the cup lid body 1, fingerprint recognition can be performed through the fingerprint touch panel 2. After successful recognition, the fingerprint touch panel 2 controls the motor 41 to rotate half a turn. The transmission end of the motor 41 drives the rotating base 42 to rotate, which in turn causes the pull block 43 on one side of the rotating base 42 to rotate. When the pull block 43 rotates, it gives the lifting block 44 an upward force, compressing the spring 47, causing the lifting block 44 to slide upward along the lifting guide rail 45, and driving the locking pin 46 to move upward together until the locking pin 46 exits from the lock hole 7, unlocking the cup lid body 1. The user can then unscrew the cup lid body 1 to drink water. The fingerprint touch panel 2 will automatically control the motor 41 to rotate half a turn in the opposite direction. At this time, the restoring force of the spring 47 pushes the lifting block 44 and the locking pin 46 back to the initial position.

[0026] After drinking the water, the user attaches the cup lid body 1 to the fixing seat 6 on the top of the cup body 5 and tightens it. During the tightening process, when the locking pin 46 contacts the fixing seat 6, it will be subjected to pressure, causing the lifting block 44 to squeeze the spring 47. When the locking pin 46 moves to the locking hole 7 on the fixing seat 6, the external force on the spring 47 disappears, and the restoring force of the spring 47 pushes the lifting block 44 to slide downward in the lifting guide rail 45, thereby driving the locking pin 46 to insert into the locking hole 7, realizing the automatic locking after the cup lid body 1 is tightened.

[0027] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
