Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a thermos cup unlocking structure. Background Technology

[0002] A thermos flask is generally a water-filled container made of ceramic or stainless steel with a vacuum layer. It has a lid that seals tightly, and the vacuum insulation layer slows down the heat loss of the liquid inside, thus keeping it warm.

[0003] The inventor applied for a utility model patent before the application date, patent number: 2025205123571, which discloses a thermos cup with a voice-reminder fingerprint lock, including: a body, a spout at the top of the body, a lid assembly covering the spout, and a temperature display, a fingerprint reader, a motor, and a locking component inside the lid assembly; the output end of the locking component extends out and inserts into a latching hole, and the output end of the locking component retracts through the drive of the motor, releasing the flipping restriction of the lid assembly. Using the above method, the locking component is pressed by the cooperation of the drive arm and the unlocking pin, causing it to slide. This new unlocking method is simpler in structure, faster to assemble, and lower in cost compared to existing gear-based technologies. It also features a temperature display and fingerprint reader on the top cover to show water temperature and prevent unauthorized use, ensuring user safety. A speaker announces the water temperature to prevent scalding and provides timely reminders to replenish fluids, enhancing the user experience. However, the inventors found that this unlocking method presents excessive resistance, often resulting in failure to unlock smoothly. This necessitates replacing the motor with a higher torque one, which undoubtedly increases costs.

[0004] Therefore, there is an urgent need to design a thermos cup unlocking structure to solve one or more technical problems that are lacking in the existing technology. Utility Model Content

[0006] In a preferred embodiment, one end of the slider extends outward and is provided with a push post.

[0007] In a preferred embodiment, a return spring is provided on the outer side of the push post.

[0008] In a preferred embodiment, the locking hook is provided with a return torsion spring.

[0009] The beneficial effects of this utility model are: the cup lid can be intelligently unlocked by the cooperation of the cam, the sliding part and the locking hook; the cooperation between the sliding part and the locking hook can reduce the resistance generated during unlocking, ensure the stability of the unlocking structure, and reduce the torque requirement of the motor, thereby reducing production costs; and the structure design is reasonable and simpler.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0017] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0018] In this embodiment of the utility model, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0019] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1-3As shown, this utility model provides a thermos cup unlocking structure, characterized in that it includes: a cup lid 10, a circuit board 11 and a battery 12 electrically connected to the circuit board 11 are provided inside the cup lid 10, a motor 13 is fixedly provided in the cup lid 10, the motor 13 is electrically connected to the circuit board 11, a cam 14 is connected to the output end of the motor 13, a sliding member 15 is provided within the movement range of the cam 14, the sliding member 15 is slidably disposed inside the cup lid 10, and a locking hook 16 is provided within the movement range of the sliding member 15, the locking hook 16 is rotatably disposed inside the cup lid 10, and the working end of the locking hook 16 is exposed outside the cup lid 10.

[0021] Furthermore, one end of the sliding member 15 extends outward and is provided with a push post 151.

[0022] Furthermore, a return spring 152 is provided on the outer side of the push post 151.

[0023] Furthermore, the locking hook 16 is provided with a reset torsion spring 17.

[0024] Specifically, a cam 14 is fixedly connected to the output end of the motor 13. When the motor 13 runs, it drives the cam 14 to rotate. A slider 15 is also provided within the rotation range of the cam 14. The slider 15 is slidably connected to the cup lid 10 and can slide back and forth within the cup lid 10. In this embodiment, it is preferably slid horizontally. When the cam 14 rotates to a predetermined angle, the cam 14 will contact the end of the slider 15 and push the slider 15 to slide within the cup lid 10 through the drive of the motor 13. At the same time, within the movement range of the slider 15, there is also a... The locking hook 16 is rotatably connected to the cup lid 10 via a shaft at its center. The locking hook 16 can rotate relative to the shaft and has a force-receiving end and a working end. The force-receiving end corresponds to the sliding member 15. When the sliding member 15 slides under the drive of the cam 14, it contacts the force-receiving end of the locking hook 16 and pushes it to rotate. At this time, the working end rotates in the opposite direction to the rotation of the force-receiving end. The rotation of the working end engages or disengages with the latch on the cup body. Preferably, the working end disengages when rotated by the sliding member 15. Compared to previous technical solutions, this method has less resistance, ensuring smooth unlocking each time, lower requirements on the motor 13, and effectively reduces production costs.

[0025] To make better use of space, an outwardly extending push post 151 is provided at the end of the slider 15. The diameter or width of the push post 151 is smaller than that of the slider 15, so that the cup lid 10 can have more space for the locking hook 16 to rotate. In order to enable the slider 15 to reset itself after losing the force of the cam 14 for the next use, a reset spring 152 is provided on the outside of the push post 151. When the slider 15 is driven to slide by the cup cam 14, it squeezes the reset spring 152. When the cam 14 disengages from the slider 15, the slider 15 resets itself under the force of the reset spring 152.

[0026] Furthermore, to ensure that the locking hook 16 can automatically engage with the cup body's latch to lock the cup lid 10 after it is closed, a return torsion spring 17 is provided in the locking hook 16. When the locking hook 16 rotates under the drive of the cup sliding member 15, it compresses the return torsion spring 17. After the sliding member 15 returns to its original position, the locking hook 16 returns to its original position under the force of the return torsion spring 17, so that the locking hook 16 can automatically engage with the cup body's latch to lock the cup lid 10 when it is closed.

[0027] In summary, the cup lid 10 can be intelligently unlocked through the cooperation of cam 14, slider 15, and locking hook 16. The cooperation between slider 15 and locking hook 16 can reduce the resistance generated during unlocking, ensure the stability of the unlocking structure, and reduce the torque requirement of motor 13, thereby reducing production costs. Moreover, the structure is reasonable and simpler.

[0028] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
