[0002] A thermos is a water container made of ceramic or stainless steel with a vacuum layer. It has a lid that is tightly sealed. The vacuum insulation layer slows down the heat dissipation of the liquid inside, thus achieving the purpose of keeping it warm.

[0003] Most insulated cups consist of a cup body and a lid. Water is added to the cup by opening the lid. For ease of use, the lid is usually designed with at least two layers, and the upper and lower layers are generally connected in a detachable or hinged manner. During use, the lower layer is fixedly connected to the cup body, and water can be drunk by opening the upper layer from the lower layer.

[0004] To prevent unauthorized access to insulated cups, insulated cups with identification features, such as fingerprint unlocking, have appeared on the market. However, in existing insulated cups of this type, the fingerprint only locks the top and bottom layers of the lid. During use, fingerprint recognition separates the top and bottom layers of the cup body; the bottom layer of the lid is usually still connected to the cup body by screws or clips, making it easy to open the insulated cup.

[0005] This shows that the existing thermos cup structure has a low safety factor, and it is necessary to propose improvements to the existing thermos cup structure. Utility Model Content

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0028] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figure 1-8 As shown, a thermos cup with a double self-locking structure includes a cup body 1 and a cup lid. The cup lid is detachably connected to the cup body 1. The cup body 1 adopts a double-layer structure, and a gap is reserved between the two layers of the cup body 1, which is conducive to heat preservation. When in use, water or other liquids can be poured into the cup body 1 by opening the cup lid.

[0031] The cup lid includes an upper lid 2 and a lower lid 3. The lower lid 3 is detachably connected to the cup body 1 to allow water to be poured into the cup body 1. One end of the upper lid 2 is hinged to one end of the lower lid 3, and the upper lid 2 can rotate and swing along the hinge end. A damper 4 is provided on the lower lid 3 at the corresponding position of the hinge end, and a torsion spring is sleeved on the damper 4. The rotating shaft of the damper 4 is connected to the upper lid 2, and one end of the torsion spring is connected to the upper lid 2. The torsion spring can drive the upper lid 2 to rotate and swing along the hinge end, thereby opening the upper lid 2. By setting the damper 4, a buffering effect is provided, so that the upper lid 2 opens relatively slowly, avoiding the situation where the upper lid 2 opens too quickly and injuring the user, thus improving practicality.

[0032] A mounting bracket 5 is fixedly installed inside the upper cover 2. A control board 6, an identification component, and a drive component are mounted on the mounting bracket 5. The identification component and the drive component are electrically connected to the control board 6. The identification component is used to identify the user's identity information. Only when the identification component identifies the correct identity information will the control board 6 control the drive component to work. The upper cover 2 has a latch 7. One end of the latch 7 is connected to the output end of the drive component, and the other end can be locked to the lower cover 3 and the cup body 1 respectively. The drive component can drive the latch 7 to move, thereby locking or disengaging the latch 7 from the lower cover 3 and the cup body 1 respectively. In actual use, when the upper cover 2 is closed, the latch 7 engages with the lower cover 3 and the cup body 1 respectively. The user identifies their identity information through the identity recognition component. When the identity recognition component identifies the correct identity information, it sends a signal to the control board 6. At this time, the control board 6 controls the drive component to work, driving the latch 7 to disengage from the lower cover 3 and the cup body 1 respectively. After the latch 7 disengages from the lower cover 3, it drives the upper cover 2 to rotate upward along the hinge end under the action of the torsion spring, thereby opening the upper cover 2 so that the user can drink water.

[0033] Specifically, the lower cover 3 has a locking hole 31 at a position corresponding to the latch 7, and the outer wall of the cup body 1 has a locking protrusion 101 at a position corresponding to the latch 7. The driving component can drive the latch 7 to pass through the locking hole 31 and engage with the locking protrusion 101. When the upper cover 2 and the lower cover 3 are closed, the driving component will drive the latch 7 to pass through the locking hole 31 and engage with the locking protrusion 101. This thermos cup with a double self-locking structure, through the cooperation of the latch 7, the locking hole 31 and the locking protrusion 101, allows the upper cover 2 to lock both the lower cover 3 and the cup body 1, thereby preventing outsiders from opening the thermos cup at will and improving the safety factor of the thermos cup.

[0034] The identification component includes a secondary control board 8, which is fixedly mounted on the mounting bracket 5 and electrically connected to the control board 6. The secondary control board 8 has a fingerprint reader 9, one end of which extends from the upper surface of the upper cover 2. The fingerprint reader 9 is used to identify the user's fingerprint information. During use, when the fingerprint reader 9 identifies the correct fingerprint information, it sends a signal to the control board 6 through the secondary control board 8. At this time, the control board 6 controls the drive component to start working, causing the latch 7 to disengage from the lower cover 3 and the cup body 1, so that the upper cover 2 can be opened for drinking water. In other embodiments, the fingerprint reader 9 can also be replaced with other identification methods, such as card swiping, password, or other existing biometric identification methods.

[0035] The drive assembly includes a motor 10, which is fixedly mounted on the mounting bracket 5. A rotatable transmission component 11 is provided on the upper cover 2. The output end of the motor 10 is connected to the transmission component 11. One end of the transmission component 11 is provided with a screw 12, and a slider 13 is sleeved on the screw 12. The slider 13 is threadedly connected to the screw 12 and is slidably limited to the upper cover 2. The latch 7 is fixedly connected to the slider 13. During use, when the fingerprint reader 9 reads the correct fingerprint information, it sends a feedback signal to the control board 6. The control board 6 controls the motor 10 to work, driving the transmission component 11 to rotate. This, through the screw 12, causes the slider 13 to slide on the upper cover 2. The slider 13 then moves the latch 7 together, causing the latch 7 to first disengage from the locking protrusion 101 and then extend out of the locking hole 31. Afterward, the upper cover 2 will flip upward and open under the action of a torsion spring, allowing the user to drink water.

[0036] Specifically, a first bevel gear 14 is installed on the output end of the motor 10, and a second bevel gear 15 is provided at the end of the transmission component 11 away from the screw 12. The first bevel gear 14 and the second bevel gear 15 are meshed together. During operation, the motor 10 drives the first bevel gear 14 to rotate, which in turn drives the second bevel gear 15 to rotate synchronously. The second bevel gear 15 then drives the transmission component 11 and the screw 12 to rotate, thereby driving the slider 13 and the latch 7 to slide on the upper cover 2, thus achieving the purpose of driving the latch 7 to extend into or out of the locking hole 31.

[0037] To limit the movement stroke and installation position of the slider 13, a first limiting groove 21 adapted to the slider 13 is provided on the upper cover 2. The slider 13 is limited within the first limiting groove 21 and can slide within it. In actual operation, the slider 13 can be driven to slide within the first limiting groove 21 by the transmission component 11. When the slider 13 slides to the limit position, it will abut against the side wall of the first limiting groove 21. The first limiting groove 21 limits the slider 13, which can prevent the slider 13 from rotating with the transmission component 11 and also limit the movement stroke of the slider 13, preventing the slider 13 from falling out of the screw 12. This ensures that the latch 7 can extend into or out of the locking hole 31, improving the stability of the structure and the accuracy of the transmission.

[0038] The upper cover 2 is provided with a second limiting groove 22 that is adapted to the latch 7. The latch 7 is limited in the second limiting groove 22 and slides in cooperation with the second limiting groove 22. The second limiting groove 22 limits the latch 7, so that the latch 7 can be limited and fixed in the upper cover 2, thereby improving the stability of the structure.

[0039] To limit the movement direction of the latch 7, two guide protrusions 23 are provided on the inner sidewall of the second limiting groove 22, and two guide slots 71 are provided on the outer sidewall of the latch 7. Each guide protrusion 23 is inserted into a corresponding guide slot 71, and the guide protrusion 23 and the guide slot 71 are slidably engaged. When the slider 13 drives the latch 7 to move, the guide slot 71 slides on the guide protrusion 23. The cooperation between the guide protrusion 23 and the guide slot 71 can limit the movement direction of the latch 7, so that the latch 7 can accurately pass through the locking hole 31 and be engaged and fixed with the engaging boss 101, thereby improving the accuracy of transmission and the stability of operation.

[0040] To achieve automatic locking, a Hall switch 16 is provided on the control board 6, and a magnetic element 17 is provided on the lower cover 3 at a corresponding position to the Hall switch 16. When the user pushes the upper cover 2 downwards along the hinge end, after the upper cover 2 and lower cover 3 are closed, the Hall switch 16 is aligned with the magnetic element 17. At this time, the Hall switch 16 senses the magnetic element 17 and sends a signal to the control board 6. The control board 6 then controls the motor 10 to operate, driving the transmission component 11 to rotate, causing the latch 7 to extend into the locking hole 31 and pass through the locking hole 31 to engage with the locking protrusion 101, thus locking the upper cover 2, lower cover 3, and cup body 1. In this embodiment, the magnetic element 17 is a permanent magnet.

[0041] A battery 18 is fixedly mounted on the mounting bracket 5. The battery 18 is electrically connected to the control board 6 and supplies power to the control board 6, enabling the control board 6 to control the operation of the motor 10. A magnetic charging connector 19 is provided on the sub-control board 8, extending from the upper surface of the cover 2. The magnetic charging connector 19 is used to connect an external power source to charge the battery 18. The sub-control board 8 also has an indicator light 20, which can be used to display the status of the thermos, for example: a red light indicates charging, and a green light indicates full charge.

[0042] To ensure a secure connection between the lower cover 3 and the cup body 1, a connecting post 32 is provided inside the lower cover 3. The connecting post 32 extends into the cup body 1 and is threadedly connected to the inner wall of the cup body 1. When water needs to be added, the upper cover 2 can be opened, and then the lower cover 3 can be rotated to separate the connecting post 32 from the cup body 1, allowing water to be added to the cup body 1. After adding water, the connecting post 32 can be reinserted into the cup body 1, and the connection between the connecting post 32 and the cup body 1 can be tightened to secure the lower cover 3 and the cup body 1.

[0043] To facilitate drinking, a straw 33 is provided on the lower cover 3, with one end of the straw 33 extending into the cup body 1. During use, when the upper cover 2 and the lower cover 3 are opened, the liquid contained in the cup body 1 can be drawn through the straw 33.

[0044] Working principle:

[0045] Normally, the lower cover 3 is fixedly connected to the cup body 1, and the upper cover 2 is closed to the lower cover 3. When you need to drink water, you can place your finger on the fingerprint reader 9. After the fingerprint reader 9 reads the correct fingerprint information, it sends a signal to the control board 6. The control board 6 then immediately controls the motor 10 to work. The motor 10 drives the first bevel gear 14 to rotate, the first bevel gear 14 drives the second bevel gear 15 to rotate, the second bevel gear 15 drives the transmission component 11 and the screw 12 to rotate, and the screw 12 drives the slider 13 to slide in the first limiting groove 21. The slider 13 drives the latch 7 to slide on the guide protrusion 23, so that the latch 7 first disengages from the locking protrusion 101 and then extends out of the locking hole 31. When the latch 7 extends out of the locking hole 31, it will push the upper cover 2 to flip upward along the hinge end under the action of the torsion spring, thereby opening the upper cover 2. After the upper cover 2 is opened, the user can drink water from the cup body 1 through the straw 33.

[0046] When you finish drinking water and need to cover the top cover 2, push the top cover 2 downwards to flip it over. When the top cover 2 and the bottom cover 3 are closed, the Hall switch 16 is aligned with the magnetic component 17. The Hall switch 16 will send a signal to the control board 6, which will then control the motor 10 to work, driving the transmission component 11 and the screw 12 to rotate. The screw 12 will drive the slider 13 and the latch 7 to move, so that the latch 7 extends into the locking hole 31 and passes through the locking hole 31 to engage with the locking boss 101, thereby locking the top cover 2, the bottom cover 3 and the cup body 1 together.

[0047] The thermos cup can achieve double self-locking through the latch 7, which locks the upper lid 2 and the lower lid 3 at the same time, and also locks the upper lid 2 and the cup body 1. This can effectively improve the safety of the thermos cup and prevent outsiders from opening it at will.

[0048] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
