Description
Technical Field
[0001] This invention belongs to the field of water cup technology, specifically relating to a multi-station rotary control cup lid and a water cup. Background Technology
[0002] Existing cup lids, especially those that open by rotating, generally have shortcomings in terms of user experience. Most rotating cup lids rely on simple screw-on tightening or purely frictional damping to maintain the closed or open state, lacking clear positional distinctions. When operating them, users often find it difficult to accurately judge by feel whether the lid has been rotated to the correct position, whether the drinking channel is fully open or reliably closed, which can easily lead to leaks due to insufficient tightening or difficulties in opening the lid next time due to excessive force.
[0003] In addition, although some existing cup lids have introduced positioning structures, they mostly use a single elastic locking point or protrusion for limiting, which makes the operation feel stiff and the steps unclear. Moreover, they are prone to wear after long-term use, leading to positioning failure and a gradual decline in reliability. Summary of the Invention
[0004] This invention addresses the aforementioned technical problems by providing a cup lid capable of switching between at least two stations via rotation. By optimizing the tactile feedback and positioning reliability during the rotational switching process, the user receives clear and precise feedback on the switching positions. Simultaneously, a water cup incorporating this lid is also provided. The objective of this invention is achieved through the following technical solutions:
[0005] A multi-position rotary control cup lid has at least one drinking channel. It includes a bottom cover and a screw cap, the screw cap being rotatably mounted on the bottom cover. A positioning mechanism is provided between the screw cap and the bottom cover. The screw cap rotates and is positioned between at least a first position and a second position through the positioning mechanism. When the screw cap is rotated and positioned to the first position, the drinking channel is blocked and is in a closed state. When the screw cap is rotated and positioned to the second position, one of the drinking channels is opened. The positioning mechanism includes a magnetic positioning mechanism and / or a mechanical positioning mechanism.
[0006] Preferably, the drinking channel has two parts: a direct drinking channel and a suction drinking channel. The direct drinking channel is defined by the water outlet on the bottom cover and the direct drinking spout on the screw cap. The suction drinking channel is defined by a suction drinking component inserted into the screw cap. The screw cap can rotate and switch between three positions. When the screw cap is rotated to the first position, both the direct drinking channel and the suction drinking channel are blocked and closed. When the screw cap is rotated to the second position, the water outlet and the direct drinking spout are aligned to open the direct drinking channel. When the screw cap is positioned to the third position, the suction drinking channel in the suction drinking component is open.
[0007] Preferably, the magnetic positioning mechanism includes a first magnet group and a second magnet group mounted on the cap, and a third magnet group mounted on the bottom cover. Each magnet group consists of two magnets arranged symmetrically in the radial direction. When the cap rotates to the first position, the first magnet group and the third magnet group are aligned and attracted to each other, generating magnetic positioning. When the cap rotates to the second position, the second magnet group and the third magnet group are aligned and attracted to each other, generating magnetic positioning. When the cap rotates to the third position, the first magnet group and the third magnet group are aligned and attracted to each other again, generating magnetic positioning. At this time, the radial positions of the two magnets in the first magnet group are interchanged with those in the first position.
[0008] Preferably, the side of the cap is provided with a circumferential groove, and at least one axial notch is provided on the circumferential groove; the bottom cover is provided with at least one retaining rib, which can enter the circumferential groove axially through the axial notch, and form an axially limiting engagement connection with the circumferential groove after the cap rotates relative to the bottom cover.
[0009] Preferably, the circumferential groove is segmented along the circumference of the cap, including a switching section and an assembly section, wherein the axial height of the switching section is greater than the axial height of the assembly section; the retaining rib includes an assembly retaining rib and a positioning retaining rib, wherein the axial height of the positioning retaining rib is greater than the axial height of the assembly retaining rib; the mechanical positioning mechanism includes a positioning retaining rib and two positioning steps formed in the switching section and the assembly section; the positioning retaining rib can only slide in the switching section, and when the cap rotates to the first position, the positioning retaining rib abuts against one of the positioning steps, and when the cap rotates to the third position, the positioning retaining rib abuts against the other positioning step.
[0010] Preferably, the bottom of the cap is fitted with a sealing gasket, and the mechanical positioning structure includes a protrusion formed on the bottom wall of the sealing gasket and a convex ring formed on the bottom cover; when the cap rotates to the second position, the bottom end of the protrusion is embedded in the convex ring.
[0011] Preferably, the drinking component is movably inserted within the cap; the cap is equipped with an openable and closable flap, the bottom cover has a trajectory limiting structure, and the cap has a linkage guide structure; the openable and closing flap is simultaneously associated with the trajectory limiting structure and the linkage guide structure, and when the cap rotates, the openable and closing flap, driven by the linkage guide structure, is simultaneously constrained by the trajectory limiting structure to complete the opening and closing action, thereby controlling the opening and closing of the drinking channel; a linkage structure is provided between the cap and the drinking component, and when the cap rotates, the linkage structure synchronously drives the drinking component to complete the lifting and lowering action.
[0012] Preferably, when the rotating cap moves the two opening and closing tabs to the open position, the linkage structure synchronously drives the drinking component to rise, raising the drinking component to the drinking position, and the drinking channel is open when the opening and closing tabs move to the open position; when the rotating cap moves the two opening and closing tabs to the closed position, the linkage structure synchronously drives the drinking component to fall back to the storage position, and the drinking channel is blocked when the opening and closing tabs move to the closed position.
[0013] Preferably, the bottom cover has a downwardly extending mounting base formed in the center, and an axially extending guide sleeve is formed inside the mounting base; the screw cap has a hollow column extending downward in the center, and the hollow column is rotatably fitted outside the guide sleeve; the drinking assembly is axially inserted into the hollow column and the guide sleeve; the linkage structure includes a spiral groove formed in the inner wall of the hollow column, and a radial linkage rod provided on the drinking assembly and slidingly engaged with the spiral groove; when the screw cap rotates, the spiral groove drives the drinking assembly to rise and fall through the radial linkage rod.
[0014] Preferably, the drinking assembly includes a straw, a mouthpiece, and a radial linkage ring fixedly mounted on the straw. The radial linkage rod is located on the outer wall of the linkage ring and protrudes outward in the radial direction. An axial straight groove extending in the axial direction is provided on the side wall of the guide sleeve. The guide straight groove cooperates with the radial linkage rod to restrict the circumferential degree of freedom of the drinking assembly and guide it to move only in the axial direction.
[0015] Preferably, there are two spiral grooves and two radial linkage rods, which are arranged circumferentially. The spiral angle of the spiral groove is set so that within the rotation stroke of the cap between the first and third stations, the rotating cap drives the drinking assembly to complete the entire lifting stroke from the storage position to the drinking position. During the stroke of the cap rotating from the first station to the second station, the drinking assembly idles without rising, and its top end remains housed in the cavity of the hollow column. The top end of the spiral groove is provided with an upper stop point for supporting the radial linkage rod, and the bottom end of the spiral groove is provided with an idle track.
[0016] Preferably, the opening and closing piece consists of two pieces, arranged radially opposite to each other along the screw cap, with an axial linkage rod fixed at the bottom of each piece; the trajectory limiting structure consists of two track grooves on the bottom cover, and the linkage guiding structure consists of a radially extending long groove on the screw cap; the axial linkage rod passes downward into the corresponding radial long groove, and its lower end is embedded and slidably engaged with the corresponding track groove; when the screw cap rotates, the groove wall of the radial long groove moves the axial linkage rod, causing the lower end of the axial linkage rod to slide along the trajectory of the track groove, thereby driving the two opening and closing pieces to open and close synchronously.
[0017] Preferably, the drinking assembly is equipped with a check valve. When the two opening and closing plates are in the open position, they slightly compress the drinking assembly in the drinking position, forcing the check valve to open and the drinking channel to be open. When the two opening and closing plates are in the closed position, they release the compression and block the drinking assembly in the storage position, the check valve automatically closes, and the drinking channel is blocked.
[0018] Preferably, the track groove is composed of a closed section, a transition section, an arc-shaped section, and an inward-retracting end. The closed section is located at the beginning of the track groove. When both axial linkage rods are in the closed section, the two opening and closing pieces are in the closed position. The transition section is located between the closed section and the arc-shaped section, extending smoothly outward from the end of the closed section. When the axial linkage rods move in the transition section, the two opening and closing pieces gradually separate with the change of trajectory, transitioning from the closed position to the open position. The arc-shaped section is located after the transition section and is an equal-diameter arc track concentric with the cap. When the axial linkage rods run in the arc-shaped section, the two opening and closing pieces remain in the open position, with the maximum radial distance between them, and the drinking component rises fully exposed without being squeezed. The inward-retracting end is located at the end of the arc-shaped section. After the axial linkage rods enter the inward-retracting end, the two opening and closing pieces retract inward to the conduction position, applying pressure to the drinking component. A limiting step is formed at the junction of the arc-shaped section and the inward-retracting end to reliably keep the opening and closing pieces in the conduction position.
[0019] Compared with existing technologies, the multi-station rotary-controlled cup lid provided in this solution achieves switching and positioning of multiple stations through lid rotation, resulting in the following beneficial effects:
[0020] It provides at least two workstations and can flexibly switch between multiple states such as off, direct drinking, and sipping to meet the needs of different scenarios; the magnetic positioning mechanism provides a clear damping feel, and the mechanical positioning mechanism provides a clear limit stop. The two can be used alone or in combination, which not only ensures the accuracy and reliability of positioning, but also prevents accidental rotation during use.
[0021] The drinking assembly can automatically rise and fall with the rotation of the cap, and the opening and closing tabs open and close in tandem, achieving integrated control: when rotated to the drinking position, the straw automatically rises and the opening and closing tabs open to guide the drinking channel; when rotated away from the drinking position, the straw automatically lowers and is stored, and the opening and closing tabs close to block it, so there is no need to directly touch the mouthpiece throughout the process, which is hygienic and convenient.
[0022] The combination of the clamp and the circumferential groove not only achieves axial positioning and rotational assembly of the cap, but also forms part of the mechanical positioning through segmented design and height difference. It has a compact structure and a high degree of functional reusability.
[0023] The layout of the magnet groups (such as the first magnet group being swapped in position at the third station) makes full use of the circumferential space, so that the magnetic positioning can play a role in all three stations, improving the consistency of the operating feel and the product grade.
[0024] By combining the track groove with the linkage guide structure, and the linkage between the spiral groove and the radial linkage rod, the single rotational motion of the cap is precisely decomposed into the radial opening and closing motion of the opening and closing plate and the axial lifting and lowering motion of the drinking component, resulting in smooth transmission and controllable action timing.

Detailed Implementation
[0036] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:
[0037] Example 1, see Figure 1 , Figure 2 This embodiment discloses a multi-position rotary control cup lid, mainly comprising a bottom cover 1, a screw cap 2, and a drinking assembly 3. The bottom cover 1 is screwed or fastened to the cup body and has a water outlet 11. The screw cap 2 is rotatably mounted on top of the bottom cover 1, and a direct drinking spout 21 is provided at a corresponding position on the top wall of the screw cap 2. The drinking assembly 3 is axially inserted through the center of the screw cap 2 and can be raised and lowered between a storage position and a drinking position. The screw cap 2 can be switched and maintained between at least a first position (sealed closed), a second position (direct drinking channel open), and a third position (drinking channel open) through a positioning mechanism provided therein.
[0038] See Figures 3-8 The bottom cover 1 has a downwardly extending mounting base 13 formed in the center, and an axially extending guide sleeve 12 is formed inside the mounting base 13. The screw cover 2 has a hollow column 22 extending downward in the center, and the hollow column 22 is rotatably fitted outside the guide sleeve 12. The inner side wall of the screw cover 2 is provided with a circumferential groove 24, and at least one axial notch is opened on the circumferential groove 24. At least one locking rib 15 is correspondingly provided on the outer wall of the bottom cover 1. During assembly, the locking rib 15 is aligned with the axial notch and pushed axially in, and then rotated. The locking rib 15 enters the circumferential groove 24, forming an axially limited locking connection to prevent the screw cover 2 from coming off.
[0039] The circumferential groove 24 is segmented circumferentially, consisting of a switching section 241 and an assembly section 242. The axial height of the switching section 241 is greater than that of the assembly section 242. Correspondingly, the retaining shank 15 includes an assembly retaining shank 151 and a positioning retaining shank 152, with the axial height of the positioning retaining shank 152 being greater than that of the assembly retaining shank 151. Therefore, the positioning retaining shank 152 can only slide within the higher switching section 241 and cannot enter the assembly section 242. At both ends of the switching section 241, a first positioning step 243a and a second positioning step 243b are formed, together constituting a mechanical positioning mechanism. When the cap 2 rotates to the first position, the positioning retaining shank 152 abuts against one of the positioning steps; when the cap 2 rotates to the third position, the positioning retaining shank 152 abuts against the other positioning step 243, both creating a clear mechanical stop.
[0040] The magnetic positioning mechanism includes a first magnet group 51 and a second magnet group 52 mounted on the cap 2, and a third magnet group 53 mounted on the bottom cover 1. Each magnet group consists of two magnets arranged symmetrically in the radial direction. When the cap 2 rotates to the first position, the first magnet group 51 and the third magnet group 53 align and attract each other, providing magnetic positioning. When the cap 2 rotates to the second position, the second magnet group 52 and the third magnet group 53 align and attract each other. When the cap 2 rotates to the third position, the magnetic poles of the first magnet group 51 align and attract each other with the third magnet group 53 again. At this time, the two magnets of the first magnet group 51 have their radial positions interchanged in the circumferential direction compared to the first position, but they can still successfully attract the corresponding magnetic poles of the third magnet group, thus achieving the third magnetic positioning point. In this way, there is a clear magnetic attraction feeling at all three positions. At the same time, the first and third positions are supplemented by mechanical limiting with positioning steps, while the second position relies solely on magnetic force, providing a clear tactile feel.
[0041] To achieve the linkage between the opening and closing of the drinking channel and the drinking assembly 3, a linkage structure is provided between the cap 2 and the drinking assembly 3. The drinking assembly 3 includes a straw 31 and a mouthpiece 32, and a linkage ring 34 is fixed on its outer wall. A radial linkage rod 341 protrudes from the linkage ring 34. A spiral groove 221 is opened on the inner wall of the hollow column 22. The radial linkage rod 341 is slidably fitted in the spiral groove 221. An axially extending straight groove 121 is opened on the side wall of the guide sleeve 12. The radial linkage rod 341 passes through the axial straight groove 121, thereby restricting the circumferential rotation of the drinking assembly 3 and allowing it to move only along the axial direction. The helix angle of the spiral groove 221 is set as follows: during the stroke of the cap 2 rotating from the first station to the second station, the bottom end of the spiral groove 221 is provided with a free-spinning track. At this time, the radial linkage rod 341 does not produce axial displacement, and the drinking component 3 rotates without rising, with its top end remaining housed in the cavity of the hollow column 22. When the cap 2 continues to rotate from the second station to the third station, the rising section of the spiral groove 221 drives the radial linkage rod 341 to climb, thereby lifting the drinking component 3 to the drinking position. When the cap 2 rotates back from the third station, the drinking component 3 descends and returns to its original position, and the top end of the spiral groove 221 forms an upper stop point to support the drinking component in the raised state.
[0042] Meanwhile, the cap 2 is also equipped with two opposing, openable / closable plates 4. Each plate 4 has an axial linkage rod 41 fixed at its bottom. The bottom cover 1 has two track grooves 14 as a trajectory limiting structure, and the cap 2 has a radially extending groove 23 as a linkage guide structure. The axial linkage rod 41 passes downward through the corresponding radial groove 23, and its lower end is embedded and slidably engaged with the corresponding track groove 14. When the cap 2 rotates, the groove wall of the radial groove 23 will move the axial linkage rod 41, forcing its lower end to slide along the trajectory of the track groove 14, thereby controlling the opening and closing of the two plates 4. A center cover 7 is installed at the top center of the cap 2 to block the plates 4.
[0043] In this embodiment, the drinking assembly 3 is equipped with a check valve, specifically located inside the mouthpiece 32. The track groove 14 is composed of a closed section 141, a transition section 142, an arc-shaped section 143, and an inner closing end 144. When both axial linkage rods 41 are in the closed section 141, the two opening and closing plates 4 are in the closed position and radially retract. At this time, the drinking assembly 3 is in the storage position, and the opening and closing plates 4 just cover its upper end without applying pressure. The check valve automatically closes, and the drinking channel is blocked. When the cap 2 rotates into the transition section 142, the opening and closing plates 4 gradually separate. After entering the arc-shaped section 143 (concentric with the cap and of the same diameter), the two opening and closing plates 4 remain in the open position with the maximum radial distance between them. At this time, the drinking assembly 3 begins to rise under the action of the spiral groove and is not compressed after it is fully raised. As the cap 2 continues to rotate into the inner end 144, the two opening and closing pieces 4 retract from the open position to the conducting position, exerting a slight radial pressure on the mouthpiece 32, which has been raised to the drinking position. This pressure forces the check valve to open, and the drinking channel is fully open. A limiting step is formed at the junction of the inner end and the arc section, which can prevent the opening and closing pieces from accidentally loosening and keep them in the conducting position.
[0044] Therefore, when the lid is in the first position, the water outlet 11 and the drinking spout 21 are misaligned, the drinking channel is blocked, and the drinking component 3 is lowered and blocked and closed by the opening and closing piece 4, and the lid is fully locked; rotate 45 degrees to the second position, the magnetic attraction and positioning, the water outlet 11 and the drinking spout 21 are aligned, the drinking channel is opened, and the drinking channel remains closed; continue to rotate 135 degrees to the third position, the positioning latch 152 abuts against the second positioning step 243a and is positioned by magnetic attraction, the drinking channel is disconnected, the drinking component 3 rises and is lightly pressed by the opening and closing piece 4 to open the check valve, and the drinking channel is opened.
[0045] Example 2 differs from Example 1 mainly in that all magnet groups are eliminated, and mechanical limiting mechanisms are used to achieve the positioning of the three workstations.
[0046] See Figure 9 , Figure 10 The mechanical positioning mechanism in this embodiment comprises two parts. The first is the positioning step structure formed by the aforementioned circumferential groove 24 and the locking 15: the positioning locking 152 abuts against the first positioning step 243a and the second positioning step 243b to achieve clear positioning of the first and third work positions. The second is a positioning structure specifically designed for the second work position (direct drinking work position) with a set of protruding posts and convex rings. Specifically, a sealing gasket 6 is assembled at the bottom of the cap 2, and a protruding post 61 is integrally formed on the bottom wall of the sealing gasket 6; on the corresponding top surface of the cap 1, a ring of intermittent or continuous convex rings 16 is formed. When the cap 2 is rotated to the second work position, the water outlet 11 and the direct drinking port 21 are precisely aligned. At the same time, the bottom end of the protruding post 61 is precisely engaged in the convex ring 16, producing a clear engaging feeling, reliably holding the cap in the direct drinking position. When the cap is rotated out of the second work position, the protruding post slides out of the convex ring, and the damping disappears.
[0047] In this embodiment, the linkage structure of the drinking component, the structure of the opening and closing piece 4 and its cooperation with the track groove 14, as well as the feature that the drinking component 3 is squeezed in the conduction position and forces the check valve to open, are all the same as in embodiment 1, and will not be repeated here.
[0048] Example 3 provides a water cup, including a cup body and a multi-position rotary-controlled cup lid detachably connected to the mouth of the cup body as described in Example 1, Example 2, or Example 3. The bottom cover 1 is threadedly connected to the cup body, facilitating filling and cleaning for the user, ensuring convenient use and reliable sealing.
