Abstract
Description
Technical Field
[0001] This utility model relates to the field of cup lid technology, and more specifically, to a rotating cup lid. Background Technology
[0002] The cup lid is an accessory used to connect to the cup body. Currently, Chinese Patent Publication No. CN222074958U discloses a rotating cup. When not in use, the rotating cup uses a drive component to move the spout and sealing plug downwards, causing the sealing plug to close the upper opening of the channel, thus sealing the straw. When drinking water is needed, the drive component moves the spout and sealing plug upwards, moving the sealing plug away from the upper opening of the channel. This is not only simple and convenient to operate, but also eliminates the need to remove the spout, making it easy to store and carry, and preventing contamination of the water inside the cup. However, in this rotating cup structure, there is a drawback: when the spout and silicone parts need to be disassembled for cleaning, the disassembly of the spout and silicone parts is inconvenient. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a rotating cup lid, which has the advantages of being easy to use and easy to clean the rotating and sealing parts.
[0004] This utility model provides a rotating cup lid, including a lid body, a rotating component, and a sealing component made of silicone material. The rotating component has an inner cavity with a lower opening. The sealing component is embedded in the cavity and circumferentially limited by the rotating component. A suction nozzle is located at the middle of the upper end of the sealing component, extending from bottom to top through the rotating component and then outwards. A flow guide cavity communicating with the lower end of the suction nozzle is located at the bottom of the sealing component. The lid body has an inner cavity with a upper opening. The rotating component is rotatably positioned within the cavity, and the lower end of the sealing component is tightly abutted against the inner bottom of the cavity. When the rotating component drives the sealing component to rotate relative to the lid body to a first position, the flow guide cavity is horizontally misaligned with the straw connection port located at the bottom of the cavity. When the rotating component drives the sealing component to rotate relative to the lid body to a second position, the flow guide cavity communicates with the straw connection port. When the rotating component drives the sealing component to rotate relative to the lid body to a third position, the rotating component unlocks from the lid body, allowing the rotating component and sealing component to vertically detach from the lid body.
[0005] By adopting the above-described structure, this utility model allows the opening and closing of the rotary cup lid to be controlled by rotating the rotating component relative to the lid. It also enables easy separation of the rotating component from the lid, thus providing the advantages of convenient use and easy cleaning of the rotating component and the sealing component.
[0006] In one possible implementation, a plurality of limiting plates are circumferentially arranged on the inner sidewall of the cavity, and a limiting groove corresponding vertically to each of the limiting plates is provided on the outer sidewall of the upper end of the seal. Each limiting plate is inserted into the limiting groove at the corresponding position. With this structure, after the seal is embedded in the cavity, each limiting plate can be engaged with the limiting groove at the corresponding position, thereby reliably achieving circumferential limiting of the rotating part and the seal.
[0007] In one possible implementation, a venting channel with an open lower end is provided on the inner wall of the cavity, and an air inlet communicating with the venting channel is provided on the outer side of the lower end of the venting channel. When the rotating component drives the sealing component to rotate relative to the cover to a first position, the venting channel is horizontally misaligned with the air inlet located at the bottom of the cavity. When the rotating component drives the sealing component to rotate relative to the cover to a second position, the venting channel communicates with the air inlet. With this structure, after the rotating cup lid is assembled onto the cup body, when the rotating component drives the sealing component to rotate relative to the cover to the first position, the rotating cup lid is in a closed state, meaning the user cannot draw liquid from the cup body through the spout. At this time, the venting channel can be horizontally misaligned with the air inlet located at the bottom of the cavity, i.e., the venting is open. The air passage cannot connect with the air inlet. In addition, since the lower end of the seal is tightly pressed against the bottom of the cavity, the seal can seal the straw connection and the air inlet to prevent the liquid in the cup from leaking out from the straw connection and the air inlet. When the rotating part drives the seal to rotate relative to the cover to the second position, the rotating cup lid is in the open state. That is, the mouthpiece is connected to the straw connection through the guide cavity, and the user can suck up the liquid in the cup through the mouthpiece. At this time, the air passage can connect with the air inlet located at the bottom of the cavity. That is, when the user sucks up the liquid in the cup through the mouthpiece, the air in the external environment can enter the cup through the air inlet, the air passage and the air inlet to ensure the air pressure balance in the cup, so that the user can suck up the liquid in the cup.
[0008] In one possible implementation, a rotating handle is provided on the outer top of the rotating component, and the rotating handle extends in the radial direction of the rotating component; with this structure, the user can easily rotate the rotating component by rotating the handle to make the rotating component rotate relative to the cover.
[0009] In one possible implementation, a first character, a second character, and a third character are provided at intervals along the circumferential direction of the lid at the upper edge of the lid body. The first character, the second character, and the third character are used to indicate the closed state, the open state, and the unlocked state, respectively. When the rotating component drives the sealing component to rotate relative to the lid body to the first position, the rotating handle points to the first character; when the rotating component drives the sealing component to rotate relative to the lid body to the second position, the rotating handle points to the second character; and when the rotating component drives the sealing component to rotate relative to the lid body to the third position, the rotating handle points to the third character. With this structure, when the user rotates the rotating component by rotating the handle to rotate it to different positions, the user can intuitively know the current state of the rotating lid under the combined indication of the rotating handle and the first, second, and third characters, thus providing convenience to the user.
[0010] In one possible implementation, the outer peripheral wall of the upper part of the rotating component is provided with a plurality of first ribs spaced apart in the circumferential direction around the rotating component, and the inner wall of the cavity is provided with a first groove corresponding to each of the plurality of first ribs; when the rotating component drives the sealing component to rotate relative to the cover to a first position or a second position, each first rib slides into the first groove at the corresponding position; when the rotating component drives the sealing component to rotate relative to the cover to a third position, each first rib disengages from the first groove at the corresponding position; with this structure, the rotating component can be reliably connected to the cover by the sliding action of the first ribs and the first grooves; and when the rotating component drives the sealing component to rotate relative to the cover to a third position, each first rib can disengage from the first groove at the corresponding position, that is, the axial limiting state between the rotating component and the cover can be released, so that the rotating component and the sealing component can be removed from the cover, thereby facilitating the cleaning of the rotating component and the sealing component.
[0011] In one possible implementation, the upper end face of each first rib gradually slopes upward from the first end of the first rib to the tail end of the first rib. With this structure, during the process of the rotating component switching from the third position to the second position relative to the cover, or during the process of the rotating component switching from the second position to the first position relative to the cover, the upper end face of the first rib abuts against the top of the first groove, which causes the rotating component to gradually shift downward relative to the cover. This allows the rotating component to further press the sealing component tightly against the bottom of the cavity, thereby increasing the damping force between the rotating component and the cover, preventing the rotating component from freely rotating back relative to the cover, thus achieving the purpose of preventing reverse rotation.
[0012] In one possible implementation, a plurality of second ribs are provided on the outer peripheral wall of the lower part of the rotating component, spaced apart in the circumferential direction around the rotating component. A second groove, corresponding to each of the second ribs, is provided on the inner wall of the cavity. When the rotating component drives the sealing component to rotate relative to the cover to a first or second position, each second rib slides into the corresponding second groove. When the rotating component drives the sealing component to rotate relative to the cover to a third position, each second rib disengages from the corresponding second groove. With this structure, the rotating component can be reliably connected to the cover under the sliding action of the second ribs and second grooves. Furthermore, when the rotating component drives the sealing component to rotate relative to the cover to a third position, each second rib disengages from the corresponding second groove, thus releasing the axial constraint between the rotating component and the cover, allowing the rotating component and the sealing component to be removed from the cover for easy cleaning.
[0013] In one possible implementation, a notch is provided at the bottom of the first end of one of the second ribs, and a stop block adapted to the notch is provided on the inner wall of the cavity; when the rotating component drives the sealing component to rotate relative to the cover to the first position, the stop block slides into the notch and abuts against the side wall of the notch; by adopting this structure, when the rotating component drives the sealing component to rotate relative to the cover to the first position, the stop block can slide into the notch and abut against the side wall of the notch, thereby realizing the rotational limitation of the rotating component and the cover, that is, after the rotating component switches relative to the cover from the second position to the first position, the rotational limitation of the rotating component and the cover can be realized.
[0014] In one possible implementation, each second groove has a baffle rib spaced apart along its extension direction on its inner wall. When the rotating component drives the sealing component to rotate relative to the cover to the first position, the tail end of each second rib abuts against the baffle rib at the corresponding position, and the baffle abuts against the side wall of the notch. When the rotating component drives the sealing component to rotate relative to the cover to the second position, the head and tail ends of each second rib abut against the baffle rib at the corresponding position. With this structure, after the rotating component drives the sealing component to rotate relative to the cover to the first position, the tail end of each second rib can abut against the baffle rib at the corresponding position. The stop ribs abut against each other, and the stop block abuts against the side wall of the notch, thereby limiting and locking the rotation of the rotating part and the cover to prevent the rotating part from rotating freely relative to the cover. After the rotating part drives the sealing part to rotate to the second position relative to the cover, the first and last ends of each second rib abut against the stop ribs at the corresponding positions, thereby limiting and locking the rotation of the rotating part and the cover to prevent the rotating part from rotating freely relative to the cover. When the rotating part is rotated to switch the rotating part from the second position to the third position, the second rib can pass over the stop ribs and disengage from the second groove.

[0026] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0027] See Figure 1-8 As shown, this application discloses a rotating cup lid, including a lid body 1, a rotating component 2, and a sealing component 3 made of silicone material; the inner side of the rotating component 2 is provided with a cavity 21 with an opening at the lower end, the sealing component 3 is embedded in the cavity 21 and is circumferentially limited by the rotating component 2, a suction nozzle 31 is provided at the middle of the upper end of the sealing component 3, the suction nozzle 31 moves from bottom to top through the rotating component 2 and extends out of the rotating component 2, and a guide cavity 32 communicating with the lower end of the suction nozzle 31 is provided at the bottom of the sealing component 3; the inner side of the lid body 1 A recess 11 with an upper opening is provided. The rotating component 2 is rotatably disposed in the recess 11, and the lower end of the sealing component 3 is tightly abutted against the inner bottom of the recess 11. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the first position, the guide cavity 32 is horizontally misaligned with the straw connection port 12 located at the bottom of the recess 11. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the second position, the guide cavity 32 is connected to the straw connection port 12. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the third position... When the rotating part 2 is engaged, it unlocks from the lid 1 so that the rotating part 2 and the sealing part 3 can be vertically detached from the lid 1. In the above structure, the lower end of the straw connection port is connected to a straw, that is, after the rotating cup lid is assembled onto the cup body, the straw can extend into the interior of the cup body, and the lower end of the straw can reach the bottom of the cup body. With the above structure, when the rotating part drives the sealing part to rotate relative to the lid body to the first position, the flow guide cavity and the straw connection port are horizontally misaligned. At this time, the rotating cup lid is in the closed state, that is, the user cannot suck the liquid in the cup body through the straw. When the rotating part drives the sealing part to rotate relative to the lid body to the second position, the rotating cup lid is in the open state, that is, the straw is connected to the straw connection port through the flow guide cavity, and the user can suck the liquid in the cup body through the straw. When the rotating part drives the sealing part to rotate relative to the lid body to the third position, the rotating part and the lid body are in the unlocked state. At this time, the rotating part and the sealing part can be vertically detached from the lid body, which facilitates the cleaning of the rotating part and the sealing part.
[0028] The inner wall of the cavity 21 is provided with several limiting pieces 22 circumferentially, and the outer wall of the upper end of the seal 3 is provided with limiting grooves 33 that are vertically corresponding to the limiting pieces 22. Each limiting piece 22 is inserted into the limiting groove 33 at the corresponding position. With this structure, after the seal is embedded in the cavity, each limiting piece can be engaged with the limiting groove at the corresponding position, thereby reliably achieving circumferential limiting of the rotating part and the seal.
[0029] An air guide channel 23 with an open lower end is provided on the inner wall of the cavity 21. An air inlet 231 communicating with the air guide channel 23 is provided on the outer side of the lower end of the air guide channel 23. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the first position, the air guide channel 23 is horizontally misaligned with the air inlet 13 located at the bottom of the cavity 11. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the second position, the air guide channel 23 communicates with the air inlet 13. With this structure, after the rotating cup lid is assembled onto the cup body, when the rotating component drives the sealing component to rotate relative to the cover body to the first position, the rotating cup lid is in a closed state, that is, the user cannot suck up the liquid in the cup body through the spout. At this time, the air guide channel can communicate with the air inlet 13 located at the bottom of the cavity. The misalignment means that the air guide channel cannot connect with the air inlet. In addition, because the lower end of the seal is tightly pressed against the bottom of the cavity, the seal can seal the straw connection port and the air inlet to prevent liquid in the cup from leaking out from the straw connection port and the air inlet. When the rotating part drives the seal to rotate relative to the cover to the second position, the rotating cup lid is in the open state. That is, the mouthpiece is connected to the straw connection port through the flow guide cavity, and the user can suck up the liquid in the cup through the mouthpiece. At this time, the air guide channel can connect with the air inlet located at the bottom of the cavity. That is, when the user sucks up the liquid in the cup through the mouthpiece, the air in the external environment can enter the cup through the air inlet, the air guide channel and the air inlet to ensure the air pressure balance in the cup, so that the user can suck up the liquid in the cup.
[0030] A rotating handle 24 is provided on the outer top of the rotating part 2, and the rotating handle 24 extends in the radial direction of the rotating part 2. With this structure, the user can easily rotate the rotating part by rotating the handle so that the rotating part rotates relative to the cover.
[0031] The upper edge of the lid 1 is provided with a first character 14, a second character 15, and a third character 16 spaced apart along the circumferential direction of the lid 1. The first character 14, the second character 15, and the third character 16 are used to indicate the closed state, the open state, and the unlocked state, respectively. When the rotating component 2 drives the sealing component 3 to rotate relative to the lid 1 to the first position, the rotating handle 24 points to the first character 14. When the rotating component 2 drives the sealing component 3 to rotate relative to the lid 1 to the second position, the rotating handle 24 points to the second character 15. When the rotating component 2 drives the sealing component 3 to rotate relative to the lid 1 to the third position, the rotating handle 24 points to the third character 16. With this structure, when the user rotates the rotating component by rotating the handle to rotate it to different positions, the user can intuitively know the current state of the rotating lid under the indication of the rotating handle and the first, second, and third characters, thus bringing convenience to the user.
[0032] The outer peripheral wall of the upper part of the rotating component 2 is provided with a plurality of first ribs 25 spaced apart in the circumferential direction around the rotating component 2, and the inner wall of the cavity 11 is provided with a first groove 17 corresponding to the plurality of first ribs 25. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the first position or the second position, each first rib 25 slides and engages in the first groove 17 at the corresponding position. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the third position, each first rib 25 disengages from the first groove 17 at the corresponding position. With this structure, the rotating component can be reliably connected to the cover by the sliding action of the first ribs and the first grooves. And when the rotating component drives the sealing component to rotate relative to the cover to the third position, each first rib can disengage from the first groove at the corresponding position, that is, the axial limiting state between the rotating component and the cover can be released, so that the rotating component and the sealing component can be removed from the cover, thereby facilitating the cleaning of the rotating component and the sealing component.
[0033] The upper end face of each first rib 25 gradually slopes upward from the first end of the first rib 25 to the tail end of the first rib 25. With this structure, during the process of the rotating component switching from the third position to the second position relative to the cover, or during the process of the rotating component switching from the second position to the first position relative to the cover, the upper end face of the first rib abuts against the top of the first groove, which allows the rotating component to gradually shift downward relative to the cover. This allows the rotating component to further press the sealing component tightly against the bottom of the cavity, thereby increasing the damping force between the rotating component and the cover, preventing the rotating component from freely rotating back relative to the cover, thus achieving the purpose of preventing reverse rotation.
[0034] The lower outer peripheral wall of the rotating component 2 is provided with a plurality of second ribs 26 spaced apart around the circumferential direction of the rotating component 2, and the inner wall of the cavity 11 is provided with a second groove 18 corresponding to the plurality of second ribs 26. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the first position or the second position, each second rib 26 slides in the second groove 18 at the corresponding position. When the rotating component 2 drives the sealing component 3 to rotate relative to the cover 1 to the third position, each second rib 26 disengages from the second groove 18 at the corresponding position. With this structure, under the sliding action of the second ribs and the second groove, the rotating component can be reliably connected to the cover. When the rotating component drives the sealing component to rotate relative to the cover to the third position, each second rib can disengage from the second groove at the corresponding position. That is, the axial limiting state between the rotating component and the cover can be released, so that the rotating component and the sealing component can be removed from the cover, thereby facilitating the cleaning of the rotating component and the sealing component.
[0035] One of the second ribs 26 has a notch 261 at the bottom of its first end, and a stop block 181 adapted to the notch 261 is provided on the inner wall of the cavity 11. When the rotating member 2 drives the sealing member 3 to rotate relative to the cover 1 to the first position, the stop block 181 slides into the notch 261 and abuts against the side wall of the notch 261. With this structure, when the rotating member drives the sealing member to rotate relative to the cover to the first position, the stop block can slide into the notch and abut against the side wall of the notch, thereby achieving rotational limitation of the rotating member and the cover. That is, after the rotating member switches relative to the cover from the second position to the first position, rotational limitation of the rotating member and the cover can be achieved.
[0036] Each second groove 18 has a baffle 19 spaced apart along its extension direction on its inner wall. When the rotating member 2 drives the sealing member 3 to rotate relative to the cover 1 to the first position, the tail end of each second rib 26 abuts against the baffle 19 at the corresponding position, and the stop block 181 abuts against the side wall of the notch 261. When the rotating member 2 drives the sealing member 3 to rotate relative to the cover 1 to the second position, the head and tail ends of each second rib 26 abut against the baffle 19 at the corresponding position. With this structure, after the rotating member drives the sealing member to rotate relative to the cover to the first position, the tail ends of each second rib... Each of the two ribs can abut against the corresponding baffle, and the baffle can abut against the side wall of the notch, thereby limiting and locking the rotation of the rotating part and the cover to prevent the rotating part from rotating freely relative to the cover. After the rotating part drives the sealing part to rotate to the second position relative to the cover, since the first and last ends of each second rib can abut against the corresponding baffle, the rotation of the rotating part and the cover can be limited and locked to prevent the rotating part from rotating freely relative to the cover. When the rotating part is rotated to switch the rotating part from the second position to the third position, the second rib can pass over the baffle and disengage from the second groove.
[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
