[0043] In one embodiment of this utility model, such as Figures 1-7 As shown, a fingerprint-recognition automatic pop-up cup is provided, including a cup body 1, a support component 2, a pop-up component 3, a driving component 4, a recognition component 5, and a cup lid shell 6. The support component 2 is connected to the cup body 1, the pop-up component 3 is disposed on the support component 2, and the driving component 4 is connected to the support component 2 and abuts against the pop-up component 3. The recognition component 5 is disposed on the pop-up component 3, and the cup lid shell 6 is sleeved on the outside of the support component 2, the pop-up component 3, the driving component 4, and the recognition component 5, and is connected to the cup body 1.
[0044] The support assembly 2 includes a cup lid liner 21 and a spring bracket 22. The cup lid liner 21 is installed on the cup body 1, and the spring bracket 22 is installed on the cup lid liner 21.
[0045] The pop-out assembly 3 includes a spring 31 and a latch 32. The spring 31 is mounted on the spring bracket 22 and abuts against the latch 32. The latch 32 is mounted on the inner liner 21 of the cup lid.
[0046] The drive assembly 4 includes a drive motor 41 and a rotary cam 42. One end of the drive motor 41 is disposed in the inner liner 21 of the cup lid, and the other end is fixedly connected to the rotary cam 42. The rotary cam 42 is disposed in the buckle 32.
[0047] The identification component 5 includes a fingerprint recognition module 51 and a lithium battery 52. Both the fingerprint recognition module 51 and the lithium battery 52 are disposed inside the cup lid shell 6, and the fingerprint recognition module 51 and the lithium battery 52 are electrically connected.
[0048] The fingerprint recognition automatic pop-up cup provided in this application combines fingerprint recognition and automatic pop-up functions. Users only need to place their finger on the fingerprint recognition module 51, and the cup lid will automatically pop open after successful recognition. There is no need to manually press the switch or unscrew the cup lid. Even when both hands are inconvenient, the cup lid can be easily opened and closed, improving the convenience of use. The fingerprint recognition technology provides a certain degree of security for the cup. Only authorized users can open the cup lid, preventing others from opening the cup at will and protecting the safety of the items inside the cup.
[0049] The principle behind opening the lid is as follows:
[0050] When a user places their finger on the fingerprint recognition module 51, the module collects the fingerprint and compares it with pre-stored fingerprint information. If the comparison is successful, the fingerprint recognition module 51 sends a start signal to the drive motor 41. Upon receiving the signal, the drive motor 41 starts operating, driving the rotating cam 42, which is fixedly connected to it, to rotate. During rotation, the rotating cam 42, being positioned at the latch 32, applies a force to the latch 32. The spring 31, initially compressed, abuts against the support buckle 23, generating elasticity. When the force of the rotating cam 42 causes the latch 32 to open and disengage from the cup 1, the connection between the latch 32 and the cup body 1 is released. At this point, the spring 31 releases its elasticity, causing the cup lid to spring upwards, thus achieving automatic opening of the cup lid.
[0051] Users can quickly open the cup with a simple fingerprint scan, eliminating the need to manually press a switch or unscrew the lid. This design significantly improves convenience, especially when hands are occupied or complex operations are inconvenient. Using fingerprint recognition as the sole method of opening the lid ensures that only pre-registered users can open the cup. This also protects the contents of the cup, preventing unauthorized access, such as preventing children from accidentally opening cups containing hot water or hazardous materials.
[0052] In another embodiment of this utility model, the bottom of the cup lid liner 21 is provided with a liner limiting groove 211 and a cup stopper 212, the top of the cup body 1 is provided with the liner limiting groove 211, and the cup stopper 212 is provided inside the cup body 1; a motor base 213 is fixedly connected to the top of the cup lid liner 21, and a drive motor 41 is provided inside the motor base 213; the side of the cup lid liner 21 is provided with a liner positioning groove 214, and there are multiple liner positioning grooves 214, which are evenly arranged in a ring on the cup lid liner 21. The top of the cup body 1 is provided with the liner limiting groove 211, which plays a role in precise positioning and stable connection. It can ensure that the cup lid liner 21 and the cup body 1 are correctly installed, and avoid the cup lid liner 21 from shaking or shifting during use, thereby enhancing the stability of the connection between the cup lid and the cup body 1. The cup stopper 212 is provided inside the cup body 1 and plays a sealing role. It can effectively prevent liquid leakage and reduce heat loss, thus providing a certain degree of heat preservation; at the same time, it can also prevent dust, debris, and other contaminants from entering the cup, ensuring the cleanliness of the liquid inside.
[0053] In another embodiment of this utility model, a snap-fit limiting groove 215 is provided on one side of the inner lining positioning groove 214. Multiple snap-fit limiting grooves 215 are provided and are evenly arranged in a ring shape on the inner lining of the cup lid 21.
[0054] In another embodiment of this utility model, a support buckle 23 is fixedly connected to the spring bracket 22. The number of support buckles 23 is the same as that of the inner lining positioning grooves 214, and they are uniformly and annularly fixedly connected to the spring bracket 22. The support buckles 23 are inserted into the inner lining positioning grooves 214. The bottom of the spring bracket 22 is provided with a bracket limiting groove 221, and the spring 31 is disposed in the bracket limiting groove 221. The support buckles 23 and the inner lining positioning grooves 214 are the same in number and uniformly distributed in an annular shape. The cooperation between the two allows the spring bracket 22 to be accurately installed on the inner lining 21 of the cup lid. This precise positioning ensures that the position of the spring bracket 22 in the entire cup lid structure is accurate, so that the subsequently installed spring 31, buckle 32 and other components can also be in the correct position, thereby ensuring the normal operation of the spring-opening assembly 3. After the support buckles 23 are inserted into the inner lining positioning grooves 214, they can effectively limit the displacement and shaking of the spring bracket 22. During daily use of the cup, even if it is subjected to external impact or vibration, the spring bracket 22 can be firmly fixed on the inner liner 21 of the cup lid, maintaining the stability of the pop-up component 3 structure, thereby ensuring the reliability of the automatic pop-up function of the cup lid.
[0055] In another embodiment of this utility model, the buckle 32 includes a buckle body 321 and a snap fastener 322. The number of snap fasteners 322 is the same as the number of buckle limiting grooves 215, and they are uniformly and annularly fixedly connected to the buckle body 321. The snap fasteners 322 are inserted into the buckle limiting grooves 215. The buckle body 321 is provided with multiple cam limiting grooves, which are uniformly and annularly arranged on the buckle body 321. The snap fasteners 322 are the same as the number of buckle limiting grooves 215 and are evenly distributed, so that the buckle 32 can be accurately installed on the inner liner 21 of the cup lid. By inserting the snap fasteners 322 into the corresponding buckle limiting grooves 215, the buckle body 321 can be accurately positioned in a predetermined position, ensuring that its relative positional relationship with the spring 31 and the rotating cam 42 is accurate, thereby ensuring the normal operation of the entire spring-opening mechanism.
[0056] In another embodiment of this utility model, the rotating cam 42 includes a cam body 421 and a limiting cam 422. The number of limiting cams 422 is the same as the number of cam limiting grooves, and they are uniformly and annularly fixedly connected to the cam body 421. The limiting cams 422 are disposed within the cam limiting grooves. The power generated by the drive motor 41 when it operates is transmitted to the cam body 421 of the rotating cam 42. Since the drive motor 41 is fixedly connected to the cam body 421, the rotation of the motor directly drives the cam body 421 to rotate, thereby converting electrical energy into mechanical energy, providing a power source for the cup lid to pop open. The rotating cam 42 converts the circular motion of the motor into the linear motion of the latch 32. When the cam body 421 drives the limiting cam 422 to rotate within the cam limiting groove, the limiting cam 422 applies a force to the inner wall of the cam limiting groove. This force pushes the latch 32 to overcome the elastic force of the spring 31, causing the latch 32 to produce a linear displacement, thereby realizing the pop-opening of the cup lid.
[0057] In another embodiment of this utility model, a water-proof ring 7 is fixedly connected inside the cup lid shell 6, and the fingerprint recognition module 51 and the lithium battery 52 are both fixedly connected to the water-proof ring 7. During daily use, the cup inevitably comes into contact with water or other liquids. The water-proof ring 7 can form a relatively sealed space inside the cup lid shell 6, effectively preventing liquid from seeping in from gaps or other parts of the cup lid shell 6, thus avoiding contact between the fingerprint recognition module 51 and the lithium battery 52 and the liquid. Because the fingerprint recognition module 51 and the lithium battery 52 are electronic components, they may experience short circuits or damage if exposed to water, leading to fingerprint recognition failure or battery power failure. The water-proof ring 7 greatly reduces this risk and ensures the normal operation of the electronic components.
[0058] In another embodiment of this utility model, a clearance groove 61 is provided on the top of the cup lid shell 6, and the top of the fingerprint recognition module 51 is disposed in the clearance groove 61. By placing the top of the fingerprint recognition module 51 in the clearance groove 61 on the top of the cup lid shell 6, the contact position between the module and the user's finger is more reasonable, making it easier for the user to quickly and accurately place their finger in the recognition area during use, thus improving the efficiency and convenience of fingerprint recognition.
[0059] In another embodiment of this utility model, a waterproof rubber ring 8 is fixedly connected to the inner side of the cup lid shell 6, and the waterproof rubber ring 8 is fixedly sleeved on the outer side of the spring bracket 22. The spring bracket 22 has many gaps and moving parts in the cup lid structure, which can easily become channels for liquid seepage. The waterproof rubber ring 8, sleeved on its outer side, can effectively prevent liquid inside the cup and external moisture from entering the cup lid through the gap between the spring bracket 22 and the cup lid shell 6. Together with the water-resistant ring 7 and other waterproof structures, it forms multiple lines of defense, protecting electronic components such as the fingerprint recognition module 51 and the lithium battery 52 from liquid corrosion and preventing short circuits and other malfunctions.
[0060] The fingerprint recognition automatic pop-up cup provided in this application also enables convenient lid closing, as detailed below:
[0061] The waterproof rubber ring 8 inside the cup lid shell 6 is fixedly sleeved on the outside of the spring bracket 22. This structure plays a guiding and positioning role when the lid is closed. When the cup lid shell 6 approaches the cup body 1, the contact between the waterproof rubber ring 8 and the cup body 1 can provide a certain guiding force, allowing the cup lid shell 6 to be aligned with the cup body 1 more accurately, making it convenient for the user to quickly place the cup lid shell 6 in the correct position. At the same time, when the cup lid shell 6 is close to the closed position, the spring bracket 22 uses its elasticity to provide a certain pre-tightening force, assisting the cup lid shell 6 to automatically fit against the cup body 1, achieving convenient closing.
[0062] The fingerprint recognition automatic pop-up cup provided in this application combines fingerprint recognition and automatic pop-up functions. Users only need to place their finger on the fingerprint recognition module 51, and the cup lid will automatically pop open after successful recognition. There is no need to manually press the switch or unscrew the cup lid. Even when both hands are inconvenient, the cup lid can be easily opened and closed, improving the convenience of use. The fingerprint recognition technology provides a certain degree of security for the cup. Only authorized users can open the cup lid, preventing others from opening the cup at will and protecting the safety of the items inside the cup.
[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
