Description

Technical Field

[0001] This utility model relates to the field of cup lid assemblies and water cups, and particularly to a cup lid assembly and a water cup having the cup lid assembly. Background Technology

[0002] A water cup is a vessel used most often to hold liquids and is a commonly used utensil in daily life. Generally, a water cup consists of a body for holding water and a lid that seals over the opening of the body. The lid has a spout, which can be designed as a direct drinking spout or a straw that extends into the cup for sipping. The lid usually has a flip-top mechanism to seal the spout; opening the flip-top allows for drinking or sipping. However, existing water cups allow the lid to detach from the body when closed, which can easily cause water to spill out, potentially leading to burns if the liquid is hot. While some water cups allow the lid to detach only when open, this often results in a misaligned locking mechanism, making them less effective.

[0003] Chinese Patent Publication No. CN213909578U belongs to the field of water cup container technology, specifically a water cup lid locking mechanism. The flip-top has a locking hook that can be inserted into the lid; the edge of the lid has a pressing component that can flip back and forth, and the inner side of the pressing component has a limiting groove that matches the locking hook. When the locking hook is inserted into the limiting groove, the flip-top locks. When the pressing component flips, the locking hook disengages, releasing the restriction; the pressing component has a sliding key that can slide up and down, and the back of the sliding key has a limiting protrusion that passes through the pressing component and has an upward-opening positioning channel. A positioning rod that can slide up and down is located in the positioning channel. In the absence of external force, the tip of the positioning rod extends out of the positioning channel; the bottom of the flip-top has a limiting channel corresponding to the position of the positioning channel, allowing the tip of the positioning rod to be inserted into the limiting channel. This utility model has a simple structure, few components, low cost, and simple operation, effectively preventing the water cup flip-top from being accidentally opened and leaking water. This patent allows the lid to be separated from the cup body regardless of whether the lid is closed or open, resulting in poor safety.

[0004] Chinese Patent Publication No. CN118614746A discloses a cup lid for a beverage cup. The first lid (10) is threaded onto the cup rim and has several braking grooves (11b). The second lid (20) is rotatably fitted onto the first lid and has a braking through-hole (20d). A third lid (30) for covering the spout is hinged to the second lid via a braking element (314). After collecting and verifying the user's identity information, the verification unit releases the latching connection between the third and second lids. The braking element includes a cylindrical annular body, a braking arm, and a mounting arm. When the third lid is closed, it is located outside the braking through-hole. When the third lid is open, the end of the braking arm passes through the braking through-hole and embeds into a braking groove. This cup lid structure is reliable and has good safety. However, this patent achieves engagement through the rotation of the braking element contacting the braking groove of the lid. Due to the shallow depth of the braking groove, incomplete engagement is prone to occur, resulting in a flawed user experience. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing water cups, when in use, allow the lid to separate from the cup body when the lid is closed, easily causing water to spill out. When the liquid inside is hot, this can easily lead to burns. While some water cups can separate the lid only when the lid is open, they are prone to failure to properly engage and lock, resulting in poor usability. To address these shortcomings of the prior art, this invention provides a lid assembly and a water cup incorporating the lid assembly.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A cup lid assembly is constructed, comprising an upper lid and a lower lid, wherein the upper lid and the lower lid are connected on one side by a pivot, and the other side can move relative to the pivot to open or close the cup lid. A gear-mounted movable lid is provided inside the lower lid. The characteristic feature is that: a gear is provided on the gear-mounted movable lid, and a locking component is also provided on the lower lid. A pressing post is provided on the upper lid corresponding to the locking component. The pressing post rotates with the upper lid. When the upper lid rotates toward the lower lid, the pressing post pushes the locking component away from the gear, causing the lower lid and the gear-mounted movable lid to rotate asynchronously. When the upper lid rotates away from the lower lid, the locking component moves toward the gear, causing the lower lid and the gear-mounted movable lid to rotate synchronously.

[0008] Preferably, the locking assembly includes a locking block, the front end of which forms a locking post. The locking post can be inserted between the gears to make the lower cover and the gear movable cover rotate synchronously. The rear end of the locking block is connected to a locking spring. When the locking block moves away from the gear, the locking spring is compressed. The locking spring resets and pushes the locking block toward the gear.

[0009] Preferably, a force-bearing column is provided above the locking block, and a force-bearing column through hole is provided on the lower cover corresponding to the force-bearing column. Part of the force-bearing column passes through the force-bearing column through hole and is pushed by the pressing column. The upper cover is provided with a limiting groove, and the locking assembly moves within the limiting groove.

[0010] Preferably, the upper end of the force-bearing column is arc-shaped, the pressing column is correspondingly provided with an arc surface, the front end of the locking column is provided with a conical front end, the limiting groove is provided with an upper step, and the lower end of the locking block is provided with a lower step corresponding to the upper step, thereby limiting the movement distance of the locking block through the upper and lower steps.

[0011] Preferably, the lower cover is further provided with a fingerprint component, the upper cover is provided with an insertion post, the insertion post is provided with a slot, the lower cover is provided with a square hole corresponding to the insertion post, the insertion post can pass through the square hole and connect with the fingerprint component, the fingerprint component is provided with a buckle corresponding to the slot to connect the upper cover and the lower cover, the lower cover includes an upper shell and a lower shell, and the gear movable cover is placed between the upper shell and the lower shell.

[0012] Preferably, the fingerprint component includes a fingerprint motherboard, a display screen and a fingerprint unlocking area corresponding to the fingerprint motherboard, and a battery and a control board electrically connected to the fingerprint motherboard are disposed inside the upper cover. The fingerprint component also includes a motor connected to the fingerprint motherboard and a cam that rotates synchronously with the motor. The fingerprint component also includes a latch, on which a buckle is provided. The buckle corresponds to a latch. When the cam rotates, it pushes the latch to move, and the buckle and the latch can be separated. A second spring is connected to one side of the latch. When the cam rotates and causes the latch to move, the second spring is compressed. After the rotation stops, the second spring resets and pushes the latch to move, connecting the buckle and the latch.

[0013] Preferably, the cam is provided with a pushing part, the lower end of the locking tongue is provided with a sliding post corresponding to the pushing part, the locking tongue is provided with a socket, and the buckle is placed in the socket.

[0014] Preferably, the upper end of the buckle is set as an inclined surface, the sliding post is provided with a contact inclined surface, the pushing part pushes the contact inclined surface to move and the locking tongue moves, the locking tongue is provided with a stop part on both sides, and the lower cover is provided with a locking tongue sliding groove corresponding to the stop part, and the locking tongue moves in the locking tongue sliding groove.

[0015] Preferably, the upper cover is provided with a hanging ear on the side, the upper cover is provided with a pivot seat, the pivot is placed in the pivot seat, the lower end of the pivot seat is provided with a protrusion, the protrusion is placed above the hanging ear, and the upper cover opens to the maximum angle relative to the lower cover when the protrusion contacts the hanging ear.

[0016] An inclined suction tube is provided in the middle of the gear movable cover, and a suction tube pressing post is provided on the upper cover corresponding to the suction tube. When the upper cover is closed, the suction tube pressing post pushes the suction tube to move.

[0017] Alternatively, a straw may be provided in the middle of the gear-mounted cover, and a waterproof component may be provided in the middle of the upper cover corresponding to the straw. When the upper cover is closed, the waterproof component is in contact with the straw, and the waterproof component can rotate relative to the upper cover.

[0018] A water cup is constructed, including a cup body, an opening at the top of the cup body, and a water storage cavity inside. An external thread is provided at the opening, and a cup lid assembly as described above is connected to the opening. The cup lid assembly is provided with an internal thread corresponding to the external thread, and the cup body and the cup lid assembly are detachably connected by the thread.

[0019] The beneficial effects of this utility model are as follows: By setting a locking component on the cup lid assembly, when the upper lid is closed, the pressing column pushes the locking component to move. At this time, the gear-mounted movable cover and the lower cover cannot rotate synchronously, meaning the cup lid cannot be removed from the cup body. However, after the cup lid is opened, the locking spring resets and pushes the locking block between the gears, thus achieving synchronous rotation of the gear-mounted movable cover and the lower cover. This makes it more convenient to use and avoids accidentally separating the cup lid from the cup body when the lid is closed, making it safer to use. Simultaneously, the fingerprint component further enhances security. After unlocking, the second spring pushes the locking tongue to reset, allowing the upper and lower covers to be locked again, facilitating repeated use. Furthermore, in the second embodiment, a waterproof component is set on the upper cover so that the straw does not need to rotate when the lid rotates, preventing the rotation of the cup lid from affecting the seal at the straw, resulting in better sealing performance.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. 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.

[0039] A preferred embodiment of the present invention provides a cup lid assembly and a water cup having the cup lid assembly; such as... Figure 1 The device includes a cup body 1, within which a water storage cavity 10 is formed. An opening is formed at the upper end of the cup body, and a lid assembly 2 connects to the opening. External threads are provided on the outer side of the opening, and internal threads are provided on the lid assembly 2 corresponding to the external threads. The lid assembly 2 is detachably connected to the main body via these threads. Opening the lid assembly allows liquid to be injected into the water storage cavity, while closing the lid assembly stores the liquid within the cup body. Simultaneously, opening the lid assembly allows the liquid in the water storage cavity to be poured out for drinking. To improve the cup's heat retention, a double-layered material can be used for better heat preservation.

[0040] Specifically, such as Figure 2 As shown, the cup lid assembly 2 includes a lower lid 21 connected to the cup body and an upper lid 20 rotatably connected to the lower lid. The upper and lower lids are connected by a pivot 22, and a fingerprint component 3 is provided on the opposite side of the pivot to control the opening and locking of the upper lid. To facilitate drinking the liquid in the water storage cavity, a straw 4 is provided in the middle of the lower lid. The straw can be inserted into the cup body to drink the liquid.

[0041] Furthermore, such as Figure 2-3 and Figure 10-11 As shown, the lower cover 21 includes an upper shell 210 and a lower shell 211, and a gear-mounted movable cover 24 disposed between the upper shell and the lower shell. A straw hole 243 is provided in the center of the gear-mounted movable cover, and a straw 4 is placed at the straw hole. An internal thread connecting to the cup body is provided inside the gear-mounted movable cover, and a sealing ring 7 is provided at the internal thread. The sealing ring contacts the opening of the cup body to improve the sealing performance of the cup. An air hole 241 is provided on the gear-mounted movable cover 24, which communicates with the water storage cavity to prevent venting when hot liquid is poured into the water storage cavity, thus facilitating the opening of the upper cover.

[0042] Furthermore, such as Figure 2-3 and Figure 7-11As shown, a locking component 25 is provided between the upper cover 20 and the lower cover 21 to allow the cup lid assembly 2 to be separated from the cup body 1 only when the upper cover 20 is open. When the locking component is inserted between the gear movable cover 24, the lower cover and the gear movable cover can rotate synchronously; when the locking component is not inserted between the gear movable cover, the gear movable cover cannot rotate when the lower cover is rotated, and the cup lid assembly 2 cannot be removed from the cup body 1. The gear movable cover 24 includes an upper movable cover 242 and a lower movable cover. The radius of the upper movable cover is smaller than that of the lower movable cover, and the internal thread is located on the inner wall of the lower movable cover. A gear 240 is provided on the outer peripheral wall of the upper movable cover. The lower housing has an upper flange 2113 corresponding to the gear. The gear is placed inside the upper flange, and the upper flange extends to the locking component with a limiting groove 2110. The locking component moves in the limiting groove and engages with the gear 240 to achieve locking. At this time, the gear movable cover and the lower cover rotate synchronously. When it moves out of the gear in the limiting groove, the gear movable cover and the lower cover do not rotate synchronously.

[0043] Furthermore, such as Figure 8-11 As shown, the locking assembly 25 includes a locking block 250 and a locking spring 251 corresponding to the locking block. A locking pin 2502 is provided on the front side of the locking block, and a force-bearing pin 2500 is provided on the upper end. When the force-bearing pin is subjected to force, it drives the locking block to move away from the gear movable cover 24 within the limiting groove, and compresses the locking spring 251. When the locking pin 2502 moves out of the gear 240, the gear movable cover and the lower cover rotate asynchronously. After the force on the force-bearing pin is released, the locking spring resets and pushes the locking block toward the gear movable cover and moves between the gears. At this time, the gear movable cover can rotate synchronously with the lower cover. To avoid excessive reset of the locking spring, an upper step 2111 is provided in the limiting groove 2110, and a lower step 2501 is provided at the lower end of the locking block. When the upper step contacts the lower step, the locking block moves the maximum distance, and the locking pin is placed between the gears. To facilitate better engagement of the locking pin between the gears, a tapered front end 2504 is provided at the front end of the locking pin. The smaller area of ​​the tapered front end makes it easier to enter between the gears, or, when there is a certain area, it can push the gear movable cover to rotate at a small angle to allow the locking pin to enter the gear. Furthermore, due to the design of the limiting groove, the locking pin can only move along the length of the limiting groove, making its movement direction more stable.

[0044] Furthermore, such as Figure 4-6As shown, the upper housing 210 is provided with a force-bearing column through hole 2108. The force-bearing column 2500 partially passes through the force-bearing column through hole and can move within the force-bearing column through hole. The upper cover 20 is provided with a pressing plate 203 corresponding to the force-bearing column. When the upper cover rotates towards the lower cover via the pivot, the pressing plate moves close to the locking block. When it contacts the locking block, it generates a pushing force on the locking block. Since the movement trajectory of the pressing plate is rotational, the horizontal force on the locking block is converted into a pushing force, causing the locking block to slide out between the gears. In order to make the pressing plate push the locking block better, the pressing plate is provided with an arc surface 204, and the upper end of the force-bearing column is provided with an arc-shaped upper end 2503 to achieve better force pushing. The upper housing 210 is provided with a notch 2107, and the end of the limiting groove abuts against the notch, so that the upper housing and the lower housing rotate synchronously.

[0045] Furthermore, such as Figure 4-11 As shown, the gear-mounted movable cover 24 has multiple sets of outward protrusions 244 on its exterior, and corresponding inner grooves 2112 are provided inside the lower housing. The friction between the outward protrusions and the inner grooves increases the rotational friction between the gear-mounted movable cover and the lower cover. When the gear-mounted movable cover and the lower cover rotate asynchronously, the greater friction allows for better perception of the current rotation status. A circular hole 2100 is provided in the middle of the upper housing corresponding to the straw 4, and a straw pressure plate 201 is provided on the upper cover corresponding to the straw. When the upper cover is closed, the straw pressure plate exerts a pushing force on the straw, causing the straw to bend and reducing the volume of the cup lid assembly. At the same time, a support plate 202 is provided on the side of the straw pressure plate to improve its strength. A pivot seat 2101 is provided on the side of the upper shell, and a pivot hole 2102 is provided in the pivot seat. The pivot 22 is placed in the pivot hole and connected to the upper cover, so that the upper cover and the lower cover can rotate relative to each other to open or close the cup lid assembly. A hanging ear 23 is provided on the side of the lower cover. The cup can be carried by connecting a hanging rope through the hanging ear, making it more convenient to carry. At the same time, the hanging ear is located below the pivot seat, and a protrusion 2103 is provided at the lower end of the pivot seat. When the upper cover is opened, when the protrusion contacts the hanging ear, this is the maximum angle at which the upper cover can be opened. At the same time, the hanging ear and the protrusion can also prevent the upper cover from being opened too much, which may cause connection failure at the pivot.

[0046] Furthermore, such as Figure 2-6As shown in Figures 12-13, to facilitate the opening and closing of the upper cover, a fingerprint component chamber 2104 is provided on the lower cover, which contains a fingerprint component 3. The fingerprint component includes a bracket 33, a fingerprint motherboard 32 and a display screen 31 disposed within the bracket. The display screen can display the temperature of the liquid inside the cup, and a fingerprint unlocking area 30 is provided on the display screen. The cup cover assembly also contains a control board 6 connected to the fingerprint motherboard and a battery 5. The battery powers the fingerprint component, and a charging port is provided on the control board to charge the battery. The fingerprint component 3 also includes a motor 34 and a cam 35 that rotates synchronously with the motor. When the fingerprint unlocking area receives the correct fingerprint information, the motor rotates, causing the cam to rotate synchronously. The cam is provided with a pusher 350, and the fingerprint component is provided with a latch 36 corresponding to the pusher. The latch is provided with a hole 360, and a buckle 361 is provided in the hole. The upper cover is provided with a latch slot 200 corresponding to the buckle. When the upper cover is closed, the insert pin enters the hole until the buckle engages with the buckle, thus locking the upper cover and lower cover together. When the fingerprint unlocking area receives the correct fingerprint, the pusher rotates, pushing the latch to move and unlocking the buckle and latch slot. At this time, the ear shell opens the upper cover. A second spring 37 is provided at the end of the latch. The pusher pushes the latch to move, compressing the second spring. After the upper cover is opened, the second spring resets, pushing the latch to reset. When the upper cover is closed, the insert pin is inserted into the hole. The insert pin exerts a pushing force on the buckle, causing the latch to move until the pushing force disappears and the second spring resets, allowing the latch to engage with the latch slot, and the upper cover closes and locks. To facilitate smoother movement of the latch, a sliding post 362 is provided at the lower end of the latch, and a contact slope 363 is provided on the sliding post. The pushing part contacts the contact slope and pushes the latch to move. Stopping parts 364 are provided on both sides of the latch, and a latch sliding groove 2106 is provided in the fingerprint component chamber 2104 corresponding to the stopping part, so that the latch can only move in the direction of the sliding groove. At the same time, a square hole 2105 is provided above the insertion hole corresponding to the insertion hole.

[0047] Regarding the use of the cup and lid assembly, when the upper cover 20 is closed, the insertion post is inserted into the insertion hole 360. At this time, the buckle 361 and the latch 200 are locked together, locking the upper and lower covers. At this time, the pressure plate 203 pushes the locking block 250 to move and compresses the locking spring 251. The locking post 2502 is not placed between the gears. Since the locking assembly 25 is not in contact with the gears, the lower cover and the gear movable cover cannot rotate synchronously. At this time, rotating the lower cover 21 cannot remove the lid assembly 2 from the cup body 1. When the correct fingerprint is placed in the fingerprint unlocking area 30, the fingerprint main board 32 recognizes the correct fingerprint. The motor 34 rotates, driving the cam 35 to rotate, and pushes the sliding post 362 to move through the pushing part 350, causing the latch 36 to move. When the latch moves and causes the buckle 361 to move to a position where it is not locked with the latch, the upper cover 20 can be opened. At this time, the second spring 37 is compressed. After the upper cover is opened, the second spring returns to its original position, causing the latch to return to its original position. After the top cover is opened, the blocking force of the pressing column on the force-bearing column 2503 disappears, the locking spring 251 resets and pushes the locking block 250 to reset. At this time, the locking column 2502 is engaged between the gears. When the bottom cover is rotated, the gear movable cover rotates synchronously with the bottom cover under the action of the locking component and the gear, so that the cup cover assembly can be removed from the cup body and liquid can be injected into the water storage cavity. After opening the top cover, you can also drink the liquid in the water storage chamber by opening the straw. After drinking, close the top cover 20. The straw pressure plate 201 presses the straw tightly. At the same time, the pressing column 203 pushes the force-receiving column 2500 to move the locking block until the locking column 2502 moves out from between the gears. At this time, the gear movable cover and the lower cover rotate asynchronously. The top cover is closed until the insertion column is inserted into the insertion hole 360. The insertion column pushes the locking tongue 36 to move and compresses the second spring 37. When the insertion column continues to move to the same horizontal position as the buckle 361 and the bayonet 200, the insertion column can no longer push the buckle. The second spring resets and pushes the locking tongue to move so that the buckle is engaged in the bayonet. At this time, the top cover and the lower cover are locked. When the cup lid is rotated, the lower cover and the gear movable cover rotate asynchronously, and the cup lid assembly cannot be removed from the cup body.

[0048] A preferred embodiment of this utility model provides a cup lid assembly and a water cup having the cup lid assembly. The difference from embodiment one is that in embodiment one, when the upper lid 20 and lower lid 21 are closed, the straw 4 needs to be pressed together by the straw pressure plate 201. At this time, rotating the cup lid assembly can easily lead to leakage due to compromised straw sealing. To solve this problem, such as... Figure 14-15 As shown, the straw 4 is set perpendicular to the lower cover 21. At this time, there is no need to set a straw pressure plate on the upper cover. Instead, a waterproof component 206 is set in the middle of the upper cover corresponding to the straw position. A waterproof component cavity 205 is set in the middle of the upper cover corresponding to the waterproof component. The waterproof component is placed in the waterproof component cavity, and the lower end of the waterproof component is better in contact with the upper end of the straw to seal the straw. At this time, the straw will not rotate when the cup lid is rotated.

[0049] Furthermore, such as Figure 16-17As shown, the waterproof component cavity 205 includes an annular cavity wall 2050, and a sliding groove 2051 is provided inside the annular cavity wall. The waterproof component is placed inside the waterproof component cavity, and the waterproof component includes waterproof silicone 2061 and a waterproof silicone fixing member 2060 that connects the waterproof silicone and the top cover. A connecting hole 20600 is provided in the middle of the waterproof silicone fixing member, and a connecting post 20610 is provided in the middle of the waterproof silicone corresponding to the connecting hole. The connecting post passes through the connecting hole to connect the waterproof silicone with the waterproof silicone fixing member. At the same time, a clamping post 20611 is formed above the connecting post, and the radius of the clamping post is larger than the radius of the connecting hole. To allow for some sliding between the waterproof component and the top cover, multiple sets of locking teeth 20601 are provided on the upper part of the waterproof silicone fastener. The locking teeth can slide within the sliding groove 2051, and gaps 20602 are left between the multiple sets of locking teeth to facilitate sliding. The waterproof component can also be removed from the top cover for cleaning. The lower end of the waterproof silicone forms a sealing surface 20612, which can be spherical to better fit the straw, increasing the straw's sealing performance without affecting rotation.

[0050] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
