[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] To accommodate diverse drinking needs, most existing water cups employ a dual-drink lid structure, with a direct drinking spout and a straw mounting hole on the lid, along with corresponding sealing structures to open and close both openings. However, this structure results in a large number of lid components and a complex external shape, hindering lid design and limiting product aesthetic flexibility. To address these shortcomings of existing technology, this application provides a rotating lid and water cup to solve the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a rotating cup lid and a water cup.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 7This invention discloses a rotating cup lid, comprising: The cup lid body 1 has a drinking spout 11 and an air hole 12 on it. Control unit 2 is rotatably mounted on the cup lid body 1. One end of the control unit 2 is provided with a rotating shaft 21, which is rotatably engaged with the cup lid body 1. One end of the rotating shaft 21 passes through the cup lid body 1 and extends to the bottom of the cup lid body 1. A connecting plate 3 is connected to one end of the control unit 2 located below the cup lid body 1 and can rotate synchronously with the control unit 2; the connecting plate 3 is provided with a first sealing part 31, a second sealing part 32 and a suction member 33; the first sealing part 31 is used to block the drinking port 11, the second sealing part 32 is used to block the air hole 12, and the suction member 33 is used to dock with the drinking port 11; rotating the connecting plate 3 can make the drinking port 11 switch sequentially to a blocked state, a direct drinking state and a sucking state docked with the suction member 33.

[0020] This application uses the control unit 2 to drive the connecting plate 3 to rotate. The first sealing part 31, the second sealing part 32 and the suction part 33 integrated on the connecting plate 3 can achieve orderly switching between multiple working modes such as blocking the drinking spout 11, direct drinking and suction. The integration of various functional components on the connecting plate 3 simplifies the overall structure of the cup lid, reduces the number of parts, and facilitates the design of the cup lid's appearance. At the same time, the air hole 12 can cooperate to realize the adjustment of the air pressure inside the cup, ensuring smooth water flow in the direct drinking and suction modes. The mode switching operation is simple and convenient to use.

[0021] In specific implementation, the cup lid body 1 is provided with a shaft hole 17 adapted to the rotating shaft 21, and the rotating shaft 21 and the shaft hole 17 are slidably and sealingly adapted. In the initial state, the first sealing part 31 blocks the drinking mouth 11, the second sealing part 32 blocks the air hole 12, and the suction member 33 can be set in any other position; when the first sealing part 31 releases the blockage of the drinking mouth 11, the second sealing part 32 simultaneously releases the blockage of the air hole 12.

[0022] In one embodiment, the connecting plate 3 is elongated, and the first sealing part 31 and the suction member 33 are respectively disposed at both ends of the connecting plate 3. The first sealing part 31 and the second sealing part 32 are both sealing blocks with rubber sleeves on the outside. When the sealing block is rotated to the position corresponding to the drinking mouth 11 and the air hole 12, it seals the drinking mouth 11 and the air hole 12 on the inside of the cup lid body 1. One end of the suction member 33 is provided with a hollow docking end 331 with a rubber sleeve. The bottom of the docking end 331 is connected to a straw 332 extending towards the cup body 5. When the docking end 331 is rotated to the position of the drinking mouth 11, it docks with the drinking mouth 11 on the inside of the cup lid body 1, and drinking water can be achieved by sucking through the drinking mouth 11.

[0023] In this application, the elongated connecting plate 3 separates the first sealing part 31 and the suction part 33 at both ends. During rotation, the sealing and suction working modes can be easily switched. The sealing block and the suction part 33 are equipped with rubber sleeves on the outside of the docking end 331, which can improve the sealing effect between the sealing block and the drinking port 11 and the air hole 12, effectively preventing water and air leakage. The hollow docking end 331, together with the downward extending straw 332, realizes the inner docking and sucking of water. The overall structure is integrated on the connecting plate 3, and the components are arranged compactly, which helps to simplify the external shape of the cup lid, while ensuring the reliability of the seal and the drinking experience.

[0024] Preferably, the sleeve can be made of rubber, latex or silicone.

[0025] In one embodiment, the connecting plate 3 has a through hole 34 in the middle that is adapted to the rotating shaft 21. One end of the rotating shaft 21 passes through the through hole 34 and extends to the bottom of the connecting plate 3. The outer peripheral wall of the rotating shaft 21 located below the connecting plate 3 has an annular groove 211. The connecting plate 3 has a snap-fit ​​4 at the bottom. The snap-fit ​​4 engages with the annular groove 211 to limit the assembly position of the connecting plate 3 relative to the rotating shaft 21.

[0026] In this application, the rotating shaft 21 and the connecting plate 3 are fitted with a through hole 34 and are locked in place by a snap-fit ​​part 4 and an annular slot 211. After the locking part 4 is released, the connecting plate 3 can be removed from the rotating shaft 21, which facilitates the disassembly and cleaning of the connecting plate 3 and its sealing parts and suction parts 33, reduces dirt accumulation, and improves the hygiene of the product.

[0027] Preferably, the snap-fit ​​4 is U-shaped and snaps onto both sides of the rotating shaft 21. The bottom of the snap-fit ​​4 has a cover plate to cover the bottom of the rotating shaft 21.

[0028] Preferably, the rotating shaft 21 has a guide groove 212 that penetrates the side wall and bottom of the rotating shaft 21 at the position corresponding to the through hole 34, and a guide block 35 that matches the guide groove 212 is provided on the inner side of the through hole 34; the guide block 35 and the guide groove 212 cooperate with each other, which can transmit the torque of the rotating shaft 21 to the connecting plate 3 and prevent misalignment of the assembly direction between the rotating shaft 21 and the connecting plate 3.

[0029] In one embodiment, the bottom of the cup lid body 1 is provided with a first stop 13, and the connecting plate 3 is provided with a second stop 36 that cooperates with the first stop 13. When the connecting plate 3 rotates forward to the position where the first blocking part 31 blocks the drinking port 11, the first stop 13 contacts one side of the second stop 36, restricting the connecting plate 3 from continuing to rotate forward. When the connecting plate 3 rotates in the reverse direction to the position where the sucking member 33 aligns with the drinking port 11, the first stop 13 contacts the other side of the second stop 36, restricting the connecting plate 3 from continuing to rotate in the reverse direction.

[0030] By using the double-sided abutment limit of the first stop 13 and the second stop 36, the rotation stroke of the connecting plate 3 is constrained in both directions, so that the connecting plate 3 can accurately stop at the target working position of sealing the drinking port 11 and the suction component 33 docking with the drinking port 11, avoiding excessive rotation that causes misalignment, ensuring the sealing effect and the docking accuracy of the suction component 33 and the drinking port 11, the mode switching positioning is clear, and the reliability of use is improved.

[0031] It should be noted that when the drinking spout 11 is open and the suction member 33 has not yet connected with the drinking spout 11, the drinking spout 11 is in a direct drinking state.

[0032] Preferably, the first stop 13 consists of two first blocks connected by an arc-shaped connecting plate 3, and the second stop 36 consists of two second blocks side by side.

[0033] In one embodiment, the cup lid body 1 is provided with a boss 14 below the drinking spout 11. The boss 14 is provided with a guide slope. The guide slope is used to guide the connecting plate 3 to slide along the guide slope to the top of the boss 14, so that the corresponding end of the connecting plate 3 forms a tight fit with the drinking spout 11.

[0034] In this application, the guide slope on the boss 14 can guide and lift the connecting plate 3 during the rotation of the connecting plate 3, so that the corresponding end of the connecting plate 3 can slide smoothly into place and reliably abut against the drinking port 11, ensuring the sealing performance when blocking or sucking.

[0035] In one embodiment, the control part 2 is in the shape of a sheet, one end of the control part 2 is connected to the rotating shaft 21, and the other end of the control part 2 can rotate to block the drinking port 11; when the control part 2 blocks the drinking port 11, the first blocking part 31 blocks the drinking port 11, so that the drinking port 11 is in a blocked state.

[0036] In this application, the rotating plate-shaped control unit 2 can block the external side of the drinking port 11. At the same time, the linkage shaft 21 drives the first sealing part 31 on the connecting plate 3 to complete the internal sealing of the drinking port 11, forming double protection inside and outside, improving the sealing and dustproof effect of the drinking port 11 after it is closed. The control unit 2 is exposed and can be directly rotated and operated by the user. The structure is simple and the mode switching operation is intuitive and convenient.

[0037] In one embodiment, the bottom of the control unit 2 is provided with a limiting block 22, and the top surface of the cup lid body 1 is provided with an arc-shaped limiting groove 15 at the position corresponding to the limiting block 22; when the drinking mouth 11 is in a blocked state, the limiting block 22 is located at one end of the arc-shaped limiting groove 15; when the drinking mouth 11 is in a sucking state, the limiting block 22 moves to the other end of the arc-shaped limiting groove 15.

[0038] Although this application has set up a first stop 13 and a second stop 36 to cooperate in achieving inner limit of the connecting plate 3, since the control part 2 has a long lever arm, if only the first stop 13 and the second stop 36 bear the limit load, when the connecting plate 3 is rotated into place and subjected to the external force of continued rotation, the injection-molded shaft 21 is prone to torsional deformation due to large torque, which affects the assembly accuracy and service life. Therefore, this application adds a limit block 22 to the bottom of the control part 2, which cooperates with the arc-shaped limit groove 15 on the top surface of the cup lid body 1 to achieve secondary limit of the overall rotation stroke from the outside of the control part 2, share the limit force, and avoid the shaft 21 from bearing excessive torque and torsional deformation. It cooperates with the first stop 13 and the second stop 36 set on the inner side of the connecting plate 3 to form an inner and outer double limit structure, which effectively protects the injection-molded shaft 21 and improves the positioning reliability of the whole machine and the durability of the product.

[0039] In one embodiment, the bottom of the control unit 2 is also provided with a positioning rod 23, and the top surface of the cup lid body 1 is provided with a plurality of positioning grooves 16 along the movement trajectory of the positioning rod 23; when the drinking port 11 is in a blocked state, a direct drinking state and a sucking state respectively, the positioning rod 23 can be sequentially inserted into the positioning groove 16 in the corresponding state.

[0040] In practice, initially, the positioning rod 23 is located in one of the positioning slots 16. When the control unit 2 rotates, it can cause the bottom of the positioning rod 23 to deform, passing over the positioning slot 16 and entering the other positioning slot 16. Through the engagement of the positioning rod 23 with the corresponding positioning slot 16, positioning can be achieved in various working modes such as blocking, direct drinking, and sucking. When rotating to switch modes, a noticeable shift feedback is generated, further improving the alignment accuracy in each working mode, preventing the control unit 2 from rotating unexpectedly, optimizing the user's operating feel, and assisting the front and rear limiting structures to further improve the overall working stability of the cup lid.

[0041] The present invention also discloses a water cup, which includes a cup body 5 (not shown in the figure) and the aforementioned rotating cup lid is provided on the cup body 5.
