[0002] In the use of kettles and other containers (such as thermos cups and health pots), the stopper or lid, as a container accessory, is a core component controlling the flow of liquid and sealing the container. Traditional stoppers often adopt a "pull-out" or "multi-turn screw-on" structure, which is inconvenient to open and close.

Therefore, there is a need for a stopper that is easy to open and close, provides a reliable seal, and can be expanded with intelligent functions. By optimizing the structural fit and linkage of various components, the user experience and functional practicality can be improved. Summary of the Invention

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model. Example

[0017] Reference Figure 1-9 As illustrated, this embodiment overcomes the shortcomings of existing kettle stoppers, such as cumbersome operation, unreliable sealing, and lack of status feedback, and provides a kettle stopper that can be opened and closed by rotation, has reliable sealing performance, and can be expanded with intelligent functions.

[0018] Specifically, in order to achieve opening and closing by rotation, the stopper in this embodiment includes a screw cap 5, a cap body 1, a limiting plate 2, a driving mechanism 4, and a water sealing component 3 assembled from top to bottom. The rotation of the screw cap 5 can drive the driving mechanism 4 to move the water sealing component 3 up and down at the bottom of the cap body 1, thereby opening or closing the channel at the bottom, thus achieving opening and closing by rotation.

[0019] Furthermore, the cap body 1, serving as the basic support component for the stopper, has an internal cavity comprising a guide post 11 and a flow guide 12. The guide post 11 is indirectly supported within the cavity by a mounting plate at its bottom, and has internal space for movement. An outlet channel 13 is formed between the outer wall of the guide post 11 and the inner wall of the cap body 1, through which fluid can flow. The portion of the mounting plate located within the outlet channel 13 has through holes for fluid passage, while the remainder is used for mounting and supporting the guide post 11 and the cap body 1.

[0020] The flow guide 12 is located at the edge of the cover body 1 and is used to guide the flow of fluid in the outlet channel 13, that is, the fluid can be discharged through the flow guide 12.

[0021] In order to seal the top of the outlet channel 13, in this embodiment, the limiting plate 2 covers the top of the cover body 1 and blocks the top of the outlet channel 13, and is provided with a notch 21 that forms the outlet 22 with the guide part 12. The fluid in the outlet channel 13 flows from the outlet channel 13 to the notch 21 under the guiding action of the guide part 12, and finally flows out from the outlet 22 formed.

[0022] In order to seal the bottom of the outlet channel 13, in this embodiment, the water sealing element 3 is fitted onto the bottom of the cover body 1. The water sealing element 3 opens or closes the bottom of the outlet channel 13 by moving up and down. That is, when the water sealing element 3 does not contact the bottom of the outlet channel 13 to seal, it is in the open state. When the water sealing element 3 contacts the bottom of the outlet channel 13 to seal, it is in the closed state.

[0023] Furthermore, in this embodiment, a driving mechanism 4 is provided to realize the up-and-down movement of the sealing element 3, thereby achieving opening and closing. Specifically, the driving mechanism 4 includes a driving seat 41 and a driving buckle 42. The driving seat 41 is located below the limiting plate 2 and can rotate relative to the limiting plate 2, while the limiting plate 2 cannot rotate. The driving buckle 42 is located below the driving seat 41. By rotating the driving seat 41, the driving buckle 42 is driven to move up and down within the guide post 11. The lower end of the driving buckle 42 is connected to the sealing element 3, thereby driving the sealing element 3 to move up and down.

[0024] Furthermore, in this embodiment, the rotation of the drive seat 41 drives the drive buckle 42 to move up and down. By setting the cap 5, the cap 5 is rotatably positioned above the limiting plate 2 and rotates synchronously with the drive seat 41. That is, the limiting plate 2 is sandwiched between the cap 5 and the drive seat 41. The cap 5 and the drive seat 41 rotate synchronously with respect to the limiting plate 2. That is, the rotation of the cap 5 can drive the water sealing component 3 to move up and down.

[0025] Reference Figure 4-5 As illustrated, in one embodiment, the linkage structure between the drive seat 41 and the drive buckle 42 includes a drive block 411 at the bottom of the drive seat 41, and correspondingly, a drive inclined surface 421 and a retaining groove 422 at the top of the drive buckle 42.

[0026] During its rotation, the drive block 411 moves from the bottom to the top under the guidance of the drive ramp 421, continuously squeezing the drive ramp 421. Since the drive block 411 cannot move up and down, the drive buckle 42 is set in the guide post 11 and can move up and down. This causes the drive buckle 42 to move down, and the drive buckle 42 simultaneously drives the sealing element 3 to move down, gradually disengaging from the outlet channel 13 until the drive block 411 falls into the retaining groove 422. At this time, the sealing element 3 keeps the outlet channel 13 open, and the fluid can flow from the bottom of the outlet channel 13.

[0027] Furthermore, after the drive block 411 presses the drive buckle 42 downward, the drive buckle 42 needs to spring back to make the sealing element 3 move upward and close the opened outlet channel 13. In one embodiment, the elastic element 43 between the drive buckle 42 and the cover body 1 is used to provide the drive buckle 42 with the restoring force after being pressed down, so as to drive the sealing element 3 back to its original position and close the outlet channel 13. The elastic element 43 can be a spring or an elastic sleeve with elasticity.

[0028] It is not difficult to understand that the proposed solution in this embodiment is the best solution. Alternatively, the driving block 411 and the driving buckle 42 can be magnetically attracted. That is, under the guidance of the driving inclined surface 421, the two are always attracted together by the magnetic force. Therefore, regardless of whether the driving block 411 is at the top or bottom of the driving inclined surface 421, the driving buckle 42 can be moved up and down by reversing the direction of rotation, which means the water sealing component 3 can be moved up and down to close and open the outlet channel 13.

[0029] Reference Figure 2-3 As illustrated, to achieve synchronous rotation of the cap 5 and the drive seat 41, and to limit the rotational stroke, in one embodiment, the cap 5 has a connecting post 51 at its bottom, the drive seat 41 has a connecting hole 412, and the limiting plate 2 has a stroke groove 23. The connecting post 51 passes through the stroke groove 23 and connects to the connecting hole 412. The stroke groove 23 is used to constrain the rotational stroke of the connecting post 51. The drive seat 41 is fixedly connected to the cap 5 via the connecting post 51, and in this embodiment, a screw fixing method is used.

[0030] In one embodiment, to restrict the drive buckle 42 to only move up and down within the guide post 11 and not rotate, the side wall of the drive buckle 42 is provided with a limiting groove 423 and the inner wall of the guide post 11 is provided with a limiting rib 14. The limiting rib 14 is embedded in the limiting groove 423 to restrict the rotation of the drive buckle 42 within the guide post 11, allowing it to move only axially up and down.

[0031] In one embodiment, to achieve the positioning and installation of the limiting plate 2, the limiting plate 2 is provided with a positioning groove 24 and the cover body 1 is provided with a positioning block 15; wherein the positioning block 15 is embedded in the positioning groove 24 for positioning the installation of the limiting plate 2, so that the notch 21 is positioned correspondingly to the guide part 12, and the notch 21 and the guide part 12 form an outlet 22.

[0032] In one embodiment, the limiting plate 2 and the cap 5 are rotatably connected by a rotating shaft 52 and a bearing 54 sleeved on the rotating shaft 52. The limiting plate 2 is provided with a shaft hole 25, and the cap 5 is provided with a rotating shaft 52. The bearing 54 is sleeved on the rotating shaft 52 and is located in the shaft hole 25. It is used for the rotation of the cap 5 relative to the axis of the limiting plate 2. The bearing 54 can make the rotation of the cap 5 smooth and fluid, and the user experience is very good.

[0033] Furthermore, to achieve a reliable seal, the water-sealing component 3 in this embodiment includes a guide rod 31, a water-sealing plate 32, a water-sealing plate sealing ring 33, and a guide rod sealing ring 34. The guide rod 31 extends through the bottom hole of the guide post 11 and connects to the drive buckle 42. The water-sealing plate sealing ring 33 and the guide rod sealing ring 34 are used for sealing, and a cup-mouth sealing ring 16 is provided to provide a reliable seal. The drive buckle 42 and the guide rod 31 are detachably connected; in this embodiment, this is a threaded connection.

[0034] Furthermore, to achieve expandable smart functions for the kettle stopper, this embodiment includes a smart component 6, which includes a circuit board 61, a battery 62, a display component 63, a vibration motor 64, and a temperature sensor 65 disposed within the screw cap 5.

[0035] The display component 63 is located at the opening at the upper end of the screw cap 5, and a transparent cover 66 covers the opening of the screw cap 5. The temperature sensor 65 passes through the bottom of the screw cap 5, the limiting plate 2, the drive seat 41, the drive buckle 42, and the water seal 3 from top to bottom. The vibration motor 64 is used for vibration alerts, specifically for high water temperature alerts, lid opening / closing alerts, etc., depending on specific needs. The circuit board 61 has a charging interface 67 located at the opening 53 for external connection.

[0036] Furthermore, it includes a cover opening detection mechanism 7, which includes a magnet 71 located below the limiting plate 2 and a corresponding Hall sensor 72 located inside the cover 5; during rotation, the Hall sensor 72 obtains the rotation signal of the cover 5 based on the change of the magnetic field, and detects the opening and closing state of the bottom of the outlet channel 13.

[0037] Reference Figure 8-9 As illustrated, the operation process in this embodiment is as follows: During the opening process of the kettle stopper, the user rotates the cap 5 clockwise. The direction of rotation can be adjusted according to the structural design. Taking clockwise as an example, the cap 5 is connected to the drive seat 41 through the connecting post 51, which drives the drive seat 41 to rotate clockwise synchronously. The drive block 411 at the bottom of the drive seat 41 rotates with the drive seat 41, gradually pressing the drive slope 421 at the top of the drive buckle 42. Under the pressing force of the drive block 411, the drive buckle 42 overcomes the elastic force of the elastic element 43 and moves downward along the axial direction of the guide post 11. The limiting rib 14 and the limiting groove 423 ensure that the drive buckle 42 does not rotate and only makes linear motion. The buckle 42 drives the guide rod 31 of the sealing component 3 to move downwards in sync, and the sealing plate 32 moves downwards accordingly, separating from the bottom end of the outlet channel 13 at the bottom of the cap body 1, and the outlet channel 13 is opened; continue to rotate the cap 5 until the drive block 411 slides to the top of the drive inclined surface 421 and falls into the retaining groove 422. At this time, the position of the drive buckle 42 is locked, and the sealing component 3 remains open; the liquid in the container can flow into the outlet channel 13 of the cap body 1 under the action of gravity, be guided to the notch 21 of the limiting plate 2 through the guide part 12, and finally flow out from the outlet 22 formed by the notch 21 and the guide part 12.

[0038] Conversely, during the stopper closing process, the user rotates the cap 5 counterclockwise; the cap 5 drives the drive seat 41 to rotate counterclockwise synchronously, and the drive block 411 of the drive seat 41 disengages from the retaining groove 422 of the drive buckle 42; the elastic element 43 loses the squeezing force constraint of the drive block 411, generates a rebound deformation, and pushes the drive buckle 42 upward; the drive buckle 42 moves upward along the axial direction of the guide post 11, driving the guide rod 31 of the sealing element 3 and the sealing plate 32 to move upward synchronously; the sealing ring 33 of the sealing plate 32 gradually adheres to the bottom end of the outlet channel 13 at the bottom of the cap body 1 until the channel opening is completely blocked, and the outlet channel 13 is closed; continue rotating the cap 5 until the connecting post 51 abuts the end of the stroke groove 23, and the cap 5 can no longer rotate, and the closing process is completed.

[0039] The intelligent function and opening / closing detection process are as follows: during temperature monitoring and prompting, the temperature sensor 65 detects the liquid temperature in the container in real time and transmits the temperature signal to the circuit board 61; after processing the temperature data, the circuit board 61 displays it through the display component 63, such as a digital display or indicator light prompt; when the temperature exceeds the preset threshold, such as 60℃, it can be set through the circuit board program, and the circuit board 61 controls the vibration motor 64 to vibrate to prompt the user that the water temperature is too high and avoid scalding.

[0040] During the opening / closing status detection, when the cap 5 rotates, it causes the Hall sensor 72 to rotate around the magnet 71. The Hall sensor 72 senses changes in the magnetic field strength and direction, and outputs different electrical signals to the circuit board 61. The circuit board 61 determines the rotation angle of the cap 5 based on the changes in the electrical signals, and then identifies whether the sealing component 3 is open (i.e., the drive block 411 falls into the retaining groove 422) or closed (i.e., the drive block 411 disengages from the retaining groove 422). The opening / closing status can be fed back through the display component 63 or the vibration motor 64. For example, "Open" is displayed when it is open, and "Closed" is displayed when it is closed.

[0041] It should be noted that this embodiment aims to provide the spatial configuration and motion linkage between the limiting plate 2, the sealing component 3, the driving mechanism 4, and the screw cap 5. Through an innovative structure, the opening and closing of the kettle stopper can be achieved simply by rotating the screw cap 5, thereby improving operational convenience and ensuring reliable primary sealing. The stroke groove constrains the rotation angle of the screw cap. In other words, it involves structural component connections. The intelligent functional implementation principles and some of its own functional implementations (such as the cooperation between the kettle stopper and the cup body) are all existing and mature technologies. For example, how the sensing principle between Hall effect components is implemented, the circuit layout of components and sensors inside the circuit board 61, how the Hall sensor 72 receives the sensing signal and converts it into a control signal, and how the monitoring signal is converted to the display component 63 for display, etc. The above are just some examples of technical issues. Of course, there are also technical issues similar to or including those mentioned above, all of which are existing and mature technologies. The technical features corresponding to the technical problems to be solved are also non-essential technical features of this application. When determining whether this application is sufficiently disclosed, it should not deviate from the core meaning; therefore, they will not be described in detail.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit the scope of protection of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description and ideas. It is neither necessary nor possible to exhaustively describe all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the technical solution of this utility model should be covered within the scope of protection of the claims of this utility model.
