Description

Technical Field

[0001] This utility model relates to the field of cup lids, specifically a flip-type cup lid. Background Technology

[0002] In everyday beverage serving and carrying scenarios, the cup lid, as a core component of the cup, directly impacts the user experience and product practicality due to its sealing performance, ease of use, and structural stability. While there are many types of mainstream cup lids on the market, numerous technical defects and user pain points still exist in practical applications, making it difficult to fully meet users' core needs for "reliable sealing, convenient operation, and long-lasting durability."

[0003] In terms of sealing performance, traditional cup lids generally have shortcomings in their sealing structure design. Some cup lids that use threaded seals can achieve a certain sealing effect when tightened, but after long-term use, the threads are prone to wear, leading to increased sealing gaps. Especially when holding hot water or during transport, liquid can easily leak from the thread gaps. Other cup lids that use a press-type seal rely on the pressure between a silicone gasket and the spout to achieve a seal. However, the silicone gasket is prone to aging and deformation under long-term pressure, resulting in a decrease in sealing performance. Furthermore, improper control of the pressing pressure can lead to a seal that is too loose (leaking) or too tight (difficult to open). In addition, some flip-top cup lids only achieve closure through their own weight or a simple snap-fit, lacking a comprehensive coverage and tight fit structure for the spout. If subjected to external impact or tilting during transport, liquid can easily overflow from the spout, causing great inconvenience to users.

[0004] In terms of ease of use, the opening and closing processes of existing cup lids are generally quite cumbersome. Threaded lids require both hands to rotate, significantly increasing the difficulty of opening and closing when holding the cup with one hand (such as during commutes or office breaks). While push-button lids can be operated with one hand, some products require pressing to unlock before flipping the lid, involving multiple steps and making it difficult to control the unlocking force, posing a challenge for the elderly or children. Even some simplified flip-top lids lack stable guiding and limiting mechanisms during the flipping process, making it easy for the flipping angle to deviate. This can result in incomplete opening of the spout (affecting water flow efficiency) or excessive flipping (causing the lid to collide with the cup body and damage components), further reducing ease of use.

[0005] From the perspective of structural stability and durability, traditional cup lids have significant shortcomings in component connection and stress design. Most cup lids use a single hinge to connect the flip-top to the lid body. After repeated flipping over a long period, the hinge is prone to loosening, jamming, or even breaking due to concentrated stress, rendering the lid unusable. Some cup lid connectors (such as clips and hinges) are made of one-piece molded plastic, which lacks sufficient strength and toughness. It is prone to brittleness at low temperatures or softening and deforming at high temperatures, shortening the overall lifespan of the cup lid. Furthermore, existing cup lids lack accidental opening protection. The flip-top can easily open due to accidental contact (such as friction with other items when placed in a backpack or accidental contact by children), leading not only to liquid leakage but also potential damage to the lid components, further reducing product durability and safety.

[0006] Meanwhile, existing cup lids lack in-depth consideration of user experience in their detailed design. For example, the inner wall of the spout on some lids is vertical, making it easy for liquid to splash when poured out without guidance, especially when drinking hot water, which could scald the user. Some lids lack a cushioning structure at the point where the flip-top meets the lid body, resulting in significant impact noise when closing, and long-term impact can cause wear on the contact surface, further degrading the sealing performance. Although these minor defects do not directly affect the core function of the cup lid, they will significantly reduce the user experience in the long run, making it difficult to meet users' needs for "refined and user-friendly" products.

[0007] In conclusion, the current cup lid industry urgently needs a new type of cup lid structure that has reliable sealing performance, convenient operation, stable and durable structure, and can also take into account the user's detailed user experience. Therefore, it is essential to propose a flip-type cup lid. Utility Model Content

[0008] The purpose of this utility model is to provide a flip-type cup lid that features convenient operation, a stable and durable structure, and high sealing performance, thereby solving the existing technical defects and unmet technical requirements.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a flip-type cup lid, comprising:

[0010] A cover body, wherein a water outlet and a limiting component are provided on the cover body, and the water outlet is connected to the interior of the cover body;

[0011] A sealing component, comprising a cap and a first connector, wherein one end of the cap is rotatably connected to the inner wall of the cap body, and the other end extends downward toward the outlet to cover the lower end face of the outlet; one end of the first connector is connected to the cap, and the other end extends upward from the outlet.

[0012] One end of the cap is rotatably connected to the inner wall of the cap body, and the other end extends downward to the water outlet, covering the lower end face of the blow outlet.

[0013] The flap has one end rotatably connected to the end of the first connector away from the cover, and the other end can abut against the cover. The flap is provided with a second connector, which is slidably connected to a limiting member. The second connector can rotate relative to the limiting member, and the connection position between the second connector and the limiting member is lower than the connection position between the flap and the first connector.

[0014] The flap and the cover are pulled against each other, allowing the flap to abut against the cover and the cover to seal the outlet, achieving a closed state. When the flap flips, the flap below the outlet rotates away from the outlet, allowing the outlet to connect with the inside of the cover, thus enabling water to flow.

[0015] In this application, the limiting member can be in the form of a groove, and the corresponding second connecting member can be in the form of a column. Alternatively, the two can be arranged in opposite shapes, with the limiting member in the form of a column and the second connecting member in the form of a slot.

[0016] In this application, in the closed state, the second connector is located at the end of the limiting member closer to the center line of the cover. When the flap flips upward, the second connector moves away from the end of the limiting member that is away from the center line of the cover. During the flipping process, the horizontal height of the second connector decreases or remains unchanged (if it decreases, taking the limiting member as a groove and the second connector as a column as an example, then the height of the end of the limiting member closer to the center line of the cup is higher than its height away from the center line of the cup, extending downward from the center line of the cup towards the outer wall of the cup; if it remains stationary, the limiting member is a horizontal groove). During this process, the connection position between the first connector and the flap is higher than the first connector, and the flipping of the flap will cause the connection position between the first connector and the flap to rotate downward (the position in the water-dispensing state is lower than the position in the closed state). Therefore, the sealing leaf moves away from the water outlet, completing the connection between the water outlet and the inside of the cover. The liquid in the container is then poured out from the water outlet.

[0017] Additionally, it needs to be explained that the rotation of the flap will cause the connection position between the first connecting piece and the second connecting piece to move downwards, which can be divided into the following situations: (As will be known below, the connection position between the flap and the first connecting piece is the position of the third connecting piece, so for better explanation, the position of the third connecting piece will be used as the position of the flap and the first connecting piece in the following description)

[0018] In the first case, the central axis of the second connector is in the horizontal direction and is located between the central axis of the third connector and the actuating end. This case is easy to understand because the rotation center is the second connector, while the third connector is a certain distance away from the rotation center. Therefore, when the actuating end moves upward, the third connector naturally moves downward, lower than its original position in the closed state.

[0019] In the second scenario, the central axis of the second connector is aligned vertically with the central axis of the third connector. The third connector is directly above the second connector, and the line connecting the central axis of the third connector and the central axis of the second connector is perpendicular to the end face of the limiting member (taking the limiting member as a horizontal groove as an example). In the closed state, the distance from the central axis of the third connector to the plane of the limiting member is the greatest. When the flap flips upward, the third connector rotates around the second connector. During the subsequent rotation, the third connector will get closer and closer to the plane of the limiting member, that is, the third connector moves downward in the vertical direction.

[0020] In the third scenario (as shown in the model diagram), the central axis of the third connector is located horizontally between the central axis of the second connector and the actuating end. Therefore, as long as the horizontal distance between the third and second connectors is much smaller than the vertical distance between them, and this vertical distance is relatively small, the final position of the third connector in the water-accessible state will be lower than its position in the closed state. To better understand this, the positions of the third and second connectors can be considered as the two opposite corners of a rectangle, where the horizontal distance is much smaller than the vertical distance. The second connector is the lower left corner of the rectangle, and the third connector is the upper right corner. Flipping the rectangle reveals the trajectory of the third connector: vertically, it first moves upwards, then downwards. The critical point is when the third connector is directly above the second connector, at which point the distance between the third connector and the limiting component on the horizontal plane is at its maximum, equal to the diagonal length of the rectangle. Flipping the rectangle further significantly increases the height of the third connector. The degree of decrease (because while flipping, the position of the second connector also moves along the length direction of the limiting member), and finally the third connector will stop at a position lower than in the closed state. The degree of "small" in "and this vertical distance is small" mentioned earlier is further explained here. As we know from the above, during the rotation of the rectangle, it will first rise a certain distance, that is, the cover will rise slightly at this time. In order to reduce the impact of this process, it is only necessary to ensure that the height difference between the position of the third connector and the position when the third connector is directly above the second connector is within the deformation tolerance range of the cover and the cover body, the flap and the cover body, or the first connector, the flap and the cover plate. That is, the part of the cover plate that will rise slightly due to the rotation of the third connector mentioned earlier is converted into the deformation of the device component. This rising effect is offset by the deformation between the component connections or the deformation of the component itself. Furthermore, since this process requires a certain force to undergo deformation, this setting can also reduce the occurrence of leakage due to accidental touch causing the flap to flip, thus improving the fault tolerance rate.

[0021] Preferably, the cover is provided with a first platform, a second platform and a transition surface, the upper surface of the first platform is higher than the upper surface of the second platform, and the two are connected by the transition surface;

[0022] The water outlet is located on the upper surface of the first unit, and a first opening is provided on the side wall of the first unit, and a second opening is provided on the transition surface. In the closed state, the lower end face of the flap abuts against the opening of the water outlet on the side wall of the first unit. In the water-discharging state, the upper end face of the flap abuts against the first unit.

[0023] Preferably, the inner wall of the outlet has at least one inclined surface, the upper end of the inclined surface is connected to the first opening, and the other end extends downward toward the lower end face of the outlet in a direction close to the center line of the outlet.

[0024] The second platform is also provided with a support wall. One end of the support wall is connected to the upper surface of the second platform, and the other end extends downward toward the center line of the water outlet to the inner wall of the water outlet. This inner wall is opposite to the inclined surface. In the water discharge state, the upper surface of the flap can abut against the support wall.

[0025] Preferably, the flipper includes a toggle end and a rotating end. The rotating end is rotatably connected to the first connector. The toggle end can abut against the inner wall of the first opening in the closed state and can extend out of the first opening. A first connecting groove is provided on the toggle end. A third connector is provided on the inner side wall of the first connecting groove. The second connector is provided on both sides of the rotating end. The horizontal height of the third connector is higher than the horizontal height of the first connector.

[0026] A fourth connector is provided at the upper end of the first connector, and the third connector is rotatably connected to the fourth connector.

[0027] Preferably, the limiting member is configured as a horizontal groove, the second connecting member is configured as a column, the third connecting member is configured as a column, and the fourth connecting member is configured as a hole;

[0028] The limiting components are respectively installed on two opposing inner sidewalls of the water outlet;

[0029] The second connector is located on both sides of the flap;

[0030] The third connector is respectively disposed on two opposing inner sidewalls of the first connecting groove;

[0031] The fourth connector is disposed on both sides of the first connector.

[0032] Preferably, the first connector is further provided with a mounting hole on its side wall. One end of the mounting hole is connected to the fourth connector, and the other end gradually expands and extends toward the inclined surface to form a third opening on the other side wall of the first connector.

[0033] In this application, it is necessary to further explain that the opening size of the mounting hole at one end of the fourth connector (if it is hole-shaped) is smaller than the hole diameter of the fourth connector (if it is round, it refers to the diameter; for other shapes, it refers to the maximum inner diameter), while the size of the third opening is larger than the hole diameter of the fourth connector (as explained above).

[0034] Preferably, a first snap-fit ​​element is provided on the inner side wall of the water outlet, and a second snap-fit ​​element is provided on the side wall of the flap, wherein the first snap-fit ​​element and the second snap-fit ​​element can be snapped together.

[0035] Preferably, a fifth connector is provided on the upper side wall inside the cover body, and the fifth connector is provided with a rotating connection hole;

[0036] The cover is provided with a sixth connector, which is rotatably connected to the rotating connection hole.

[0037] Preferably, a sealing boss is provided on the upper surface of the cover near the water outlet. The upper surface of the cover abuts against the lower surface of the water outlet. The sealing boss can be fitted into the water outlet, and its outer side wall can be tightly against the inner side wall of the water outlet. The lower end of the first connector is connected to the sealing boss.

[0038] In this application, it should be explained that, in the closed state, the cover is capable of sealing the lower end face of the water outlet.

[0039] Preferably, the first connecting groove has openings on the upper, side and lower surfaces of the flip piece, and an adapter surface is provided in the first connecting groove. The adapter surface is located on the flip piece at a position opposite to the toggle end, and the adapter surface is an arc-shaped surface.

[0040] Compared with the prior art, the beneficial effects of this utility model are:

[0041] 1. The sealing of this application is reliable and leak-proof: Through the precise matching of the cap and the outlet (the upper end face of the cap abuts against the lower end face of the outlet, and the sealing boss is fitted and tightly fits against the inner wall of the outlet), and the stable contact between the flap and the cap in the closed state (the lower end face of the flap abuts against the inner wall of the first opening, and the first snap-fit ​​and the second snap-fit ​​are engaged), the sealing performance in the closed state is doubly guaranteed, effectively preventing liquid leakage and solving the problem of poor sealing of traditional cup caps.

[0042] 2. This application is easy to operate and has a high fault tolerance: the flip-type design only requires flipping the toggle end to open and close the cup lid, which can be operated with one hand, simplifying the usage process; at the same time, the position design of the third connector and the second connector requires a certain amount of force to overcome the deformation of the parts before the flip can be completed, reducing the risk of accidental contact and leakage, and improving the safety of use.

[0043] 3. The structure of this application is stable and durable: the sliding fit between the limiting part and the second connecting part, and the rotational fit between the third connecting part (column) and the fourth connecting part, provide stable guidance for the flipping plate to flip; the setting of the abutting wall can not only limit the excessive flipping of the flipping plate, but also increase the contact area and reduce the pressure, so as to avoid damage to the parts due to concentrated force; the design of the mounting hole with "one end small and one end large" not only facilitates the installation of the third connecting part, but also prevents it from falling off during the flipping process, thus extending the service life of the cup lid.

[0056] The following will refer to the appendix in the embodiments of this utility model. Figure 1-11 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0057] In the description of this utility model, it should be understood that 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 technical features indicated. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0058] Please see Figure 1-11 Embodiments of this utility model:

[0059] Example:

[0060] like Figure 1 , 2 As shown in Figures 5, 6, 9, 10, and 11: A flip-type cup lid, comprising:

[0061] Cover 1, the cover 1 is provided with a water outlet 2 and a limiting member 3, the water outlet 2 is connected to the interior of the cover 1;

[0062] The sealing component includes a cover 4 and a first connector 5. One end of the cover 4 is rotatably connected to the inner wall of the cover body 1, and the other end extends downward to the outlet 2, covering the lower end surface of the outlet 2. One end of the first connector 5 is connected to the cover 4, and the other end extends upward from the outlet 2.

[0063] One end of the cover 4 is rotatably connected to the inner wall of the cover body 1, and the other end extends downward to the water outlet 2, covering the lower end face of the blow outlet.

[0064] The flap 6 has one end rotatably connected to the end of the first connector 5 away from the cover 4, and the other end can abut against the cover 1. The flap 6 is provided with a second connector 7, which is slidably connected to the limiting member 3. The second connector 7 can rotate relative to the limiting member 3, and the connection position between the second connector 7 and the limiting member 3 is lower than the connection position between the flap 6 and the first connector 5.

[0065] The flap 6 and the cover 4 are pulled against each other, so that the flap 6 can abut against the cover 1 and the cover 4 seals the water outlet 2 to achieve a closed state. The flap 6 flips over, and the flap below the water outlet 2 rotates away from the water outlet 2, so that the water outlet 2 is connected to the inside of the cover 1, and water can flow out.

[0066] As shown in the figure: The cover 1 is provided with a first platform 8, a second platform 9 and a transition surface 10. The height of the upper surface of the first platform 8 is higher than the height of the upper surface of the second platform 9, and the two are connected by the transition surface 10.

[0067] The water outlet 2 is located on the upper surface of the first unit 8, and a first opening 11 is provided on the side wall of the first unit 8, and a second opening 12 is provided on the transition surface 10. In the closed state, the lower end face of the flap 6 abuts against the opening of the water outlet 2 on the side wall of the first unit 8. In the water-discharging state, the upper end face of the flap 6 abuts against the first unit 8.

[0068] In this embodiment, two platforms with a height difference and a second opening 12 provide sufficient space for the flipper 6 to flip, allowing it to flip at a sufficient angle. Alternatively, several first adjusting components can be provided on the cover 1, and second adjusting components can be provided on the flipper 6. The first and second adjusting components cooperate with each other to control the flipping angle of the flipper 6 during use, thereby controlling the degree of flipping of the cover 4 and thus controlling the flow rate of the outlet 2 to adapt to different situations. In this embodiment, in the closed state, the first connecting member is perpendicular to both the cover and the flipper.

[0069] Specifically, the first unit 8, the second unit 9, the transition surface 10, the outlet 2, the first opening 11, and the second opening 12 on the body work together. The upper surface of the first unit 8 is higher than that of the second unit 9, and the two are connected by the transition surface 10. This height difference provides ample space for the flapper 6 to rotate, ensuring it can smoothly rotate to the target angle and achieve complete opening and closing of the outlet 2, avoiding incomplete opening of the outlet 2 due to insufficient rotation space. The first opening 11 provides a stable support position for the flapper 6 in the closed state, allowing the lower surface of the flapper 6 to tightly fit against the inner wall of the opening, further ensuring a tight seal when closed. The second opening 12 further expands the rotation range of the flapper 6, preventing interference between the flapper 6 and the cover 1 during rotation and ensuring smooth operation. The outlet 2, as the core channel for liquid outflow, is located on the upper surface of the first unit 8, allowing it to precisely cooperate with the subsequent cover 4 and sealing protrusion 26, providing basic support for the sealing structure.

[0070] like Figure 2 and 7 As shown: The inner wall of the outlet 2 has at least one inclined surface 13. The upper end of the inclined surface 13 is connected to the first opening 11, and the other end extends downward toward the lower end face of the outlet 2 in a direction close to the center line of the outlet 2.

[0071] The second unit 9 is also provided with abutting wall 14. One end of the abutting wall 14 is connected to the upper end face of the second unit 9, and the other end extends downward toward the center line of the outlet 2 to the inner side wall of the outlet 2. This inner side wall is opposite to the inclined surface 13. In the water discharge state, the upper end face of the flap 6 can abut against the abutting wall 14.

[0072] In this embodiment, the inclined surface 13 can guide the water. In this embodiment, the inclined surface 13 is also a curved surface. In addition, the abutment wall 14 is set for two purposes: first, to limit the flipping of the flap 6 and prevent the flap 6 from flipping excessively; second, to buffer and increase the contact area with the flip cover, thereby reducing the pressure on the flip cover; and third, to make the abutment surface more stable when it abuts against the surface of the flap 6, so that the flap 6 can abut stably in the water discharge state, thereby improving the stability of the device.

[0073] like Figure 3-4 As shown: The flipper 6 includes a toggle end 15 and a rotating end 16. The rotating end 16 is rotatably connected to the first connecting member 5. The toggle end 15 can abut against the inner wall of the first opening 11 in the closed state, and it can extend out of the first opening 11. A first connecting groove 17 is provided on the toggle end 15. A third connecting member 18 is provided on the inner side wall of the first connecting groove 17. The second connecting member 7 is provided on both sides of the rotating end 16. The horizontal height of the third connecting member 18 is higher than the horizontal height of the first connecting member 5.

[0074] A fourth connector 19 is provided at the upper end of the first connector 5, and the third connector 18 is rotatably connected to the fourth connector 19.

[0075] This embodiment adopts the third case described above, which increases the stability of the device in a closed state and improves fault tolerance. The principle has been explained in detail above and will not be repeated here.

[0076] Specifically, the components of the flipper 6 are designed around the principles of "convenient flipping and stable connection." The actuating end 15 is the core part for user operation. When closed, it extends out of the first opening 11, making it easy for the user to grasp and apply force. The lid can be opened or closed with just one hand, simplifying the cumbersome operation process of traditional lids. The rotating end 16 is rotatably connected to the first connecting piece 5, providing a fulcrum for the flipper 6 to flip, ensuring that the flipping action can be stably transmitted to the sealing lid 4 to open and close the spout 2. The first connecting groove 17 has openings on the upper, side, and lower surfaces of the flipper 6. This multi-opening design provides ample space for the rotation of the third connecting piece 18 and the fourth connecting piece 19, avoiding interference between components during rotation and making the flipping smoother. The third connector 18 (column) is located on the inner side wall of the first connecting groove 17 and rotates with the fourth connector 19 (hole) of the first connector 5. Its horizontal height is higher than that of the first connector 5. At the same time, the horizontal distance between the third connector 18 and the second connector 7 is much smaller than the vertical distance. This position design makes it necessary to overcome a certain component deformation to complete the flipping of the flap 6, effectively reducing the probability of accidental opening. The second connector 7 (column) is located on both sides of the rotating end 16 and slides with the limiting part 3 (horizontal groove) of the cover 1 to provide a fixed trajectory for the flipping of the flap 6, prevent the flap 6 from swaying left and right, and ensure accurate flipping direction.

[0077] like Figure 2-7 As shown: the limiting member 3 is configured as a horizontal groove, the second connecting member 7 is configured as a column, the third connecting member 18 is configured as a column, and the fourth connecting member 19 is configured as a hole.

[0078] The limiting components 3 are respectively installed on two opposing inner sidewalls of the water outlet 2;

[0079] The second connector 7 is disposed on both sides of the flap 6;

[0080] The third connector 18 is respectively disposed on two opposing inner sidewalls of the first connecting groove 17;

[0081] The fourth connector 19 is disposed on both sides of the first connector 5.

[0082] like Figure 5-6As shown: The first connector 5 is also provided with a mounting hole 20 on its side wall. One end of the mounting hole 20 is connected to the fourth connector 19, and the other end gradually expands and extends towards the inclined surface 13, forming a third opening 21 on the other side wall of the first connector 5.

[0083] In this embodiment, the size setting of the holes at both ends of the mounting hole 20 has the following effect: the setting of the third opening 21 makes it easier for the third connector 18 to be better installed into the fourth connector 19, while the smaller hole at the other end is to prevent the third connector 18 from detaching from the fourth connector 19 during the flipping process. In this embodiment, when there is a slight deformation involved in the flipping process, it can further improve the anti-detachment effect, that is, improve the ability to withstand deformation and improve the flipping fault tolerance rate.

[0084] Specifically, the limiting component 3, the third connecting component 18, the fourth connecting component 19, and the mounting hole 20 jointly ensure the stability of the component connection and the ease of assembly. The limiting component 3 adopts the form of a horizontal groove, which is respectively set on the inner sidewalls opposite to the outlet 2. It slides with the second connecting component 7 (column) of the flap 6, which can limit the horizontal trajectory of the flap 6's flipping, ensuring that the flap 6 moves along the preset path and avoiding flipping deviation. The third connecting component 18 (column) and the fourth connecting component 19 (hole) form a rotating pair, which is the core of the connection between the flap 6 and the first connecting component 5. The fitting accuracy of the two directly affects the smoothness of the flipping. At the same time, the fitting form of the column and the hole can prevent the component from falling off during long-term use. The mounting hole 20 is opened in the first... One end of the side wall of connector 5 is connected to the fourth connector 19 (the aperture is smaller than that of the fourth connector 19), and the other end expands towards the inclined surface 13 to form a third opening 21 (the aperture is larger than that of the fourth connector 19). The large-diameter third opening 21 facilitates the quick insertion of the third connector 18 into the fourth connector 19 during assembly, while the small-diameter connecting end can hold the third connector 18 in place during the flipping process of the flip plate 6, preventing it from detaching from the fourth connector 19. This can further improve the reliability of the connection, especially in flipping scenarios where the components have slight deformation.

[0085] like Figure 2 , 3 As shown in Figures 4, 5, and 7: A first snap-fit ​​member 22 is provided on the inner side wall of the outlet 2, and a second snap-fit ​​member 23 is provided on the side wall of the flap 6. The first snap-fit ​​member 22 and the second snap-fit ​​member 23 can be snapped together.

[0086] This configuration in this embodiment further ensures the stability of the flipping plate 6 in the closed state, thereby improving the stability of this application.

[0087] Specifically, the first snap-fit ​​component 22 is located on the inner wall of the outlet 2, and the second snap-fit ​​component 23 is located on the side wall of the flap 6. The two components can be snapped together in the closed state. This snap-fit ​​connection further secures the position of the flap 6, preventing it from shifting due to vibration or minor impacts during transport, which could loosen the seal between the cover 4 and the outlet 2, leading to liquid leakage. Especially in scenarios such as backpack carrying or bumpy commutes, the snap-fit ​​structure provides extra protection for the closed state, preventing damage to the seal due to accidental external forces.

[0088] like Figure 2 and 8 As shown: A fifth connector 24 is provided on the upper side wall inside the cover 1, and a rotating connection hole 25 is provided on the fifth connector 24;

[0089] The cover 4 is provided with a sixth connector 28, which is rotatably connected to the rotating connection hole 25.

[0090] As shown in the figure: A sealing boss 26 is provided on the upper surface of the cover 4 near the outlet 2. The upper surface of the cover 4 abuts against the lower surface of the outlet 2. The sealing boss 26 can be fitted into the outlet 2, and its outer side wall can be tightly against the inner side wall of the outlet 2. The lower end of the first connector 5 is connected to the sealing boss 26.

[0091] In this embodiment, this configuration is designed to better ensure the stability of the overall device in a closed state, prevent water leakage, and improve the fault tolerance rate.

[0092] Specifically, the fifth connector 24 on the upper inner wall of the cover 1 has a rotating connection hole 25, and the sixth connector 28 on the cover 4 rotates and engages with the rotating connection hole 25, forming the rotation fulcrum of the cover 4. This connection method ensures that the cover 4 can rotate around a fixed axis, accurately achieving the switching between the states of "covering the lower end face of the outlet 2 (closed)" and "away from the outlet 2 (water outlet)," avoiding the problem of inaccurate sealing position and inability to completely cover the outlet 2 due to the offset of the rotation axis of the cover 4. At the same time, the fitting clearance between the rotating connection hole 25 and the sixth connector 28 is precisely controlled, ensuring smooth rotation and preventing the cover 4 from shaking, thus ensuring the sealing accuracy.

[0093] like Figure 5-6 As shown: The first connecting groove 17 has openings on the upper, side and lower surfaces of the flip plate 6 respectively. An adapter surface 27 is provided in the first connecting groove 17. The adapter surface 27 is located on the flip plate 6 at a position opposite to the toggle end 15, and the adapter surface 27 is an arc-shaped surface.

[0094] In this embodiment, the first connecting groove 17 is configured in such a way that it can provide more space for the rotation between the flip piece 6 and the second connecting piece 7. That is, the openings on multiple surfaces allow the flip piece 6 to rotate in a larger space, while the arc-shaped surface provides space for the two to rotate and connect, and also makes the rotation between the first connecting piece and the flip piece 6 smoother and more fluid.

[0095] Specifically, the adapter surface 27 within the first connecting groove 17 is positioned opposite the flip piece 6 and the actuating end 15, and is an arc-shaped surface. The shape of the arc-shaped surface conforms to the rotation trajectory of the third connector 18 and the fourth connector 19, reducing frictional resistance during rotation, preventing wear of components due to hard friction, and extending the service life of the connectors. At the same time, the arc-shaped surface provides ample clearance for rotation, preventing the third connector 18 from colliding or jamming with the inner wall of the first connecting groove 17 during rotation, ensuring smooth and unobstructed flipping of the flip piece 6, and improving the user's operating feel.

[0096] In addition, such as Figure 4 As shown, in this embodiment, the shape formed by the outlet 2 between the transition surface 10, the upper end surface of the first platform 8, and the upper end surface of the second platform is adapted to the shape of both sides of the flip plate 6. First, it can limit and guide the direction of reversal when flipping, so as not to sway left and right. On the other hand, whether before or after flipping, it can increase the stability of the flip plate 6 in different states, and it will not sway left and right, thus increasing the stability of the device in each state.
