[0001] This utility model relates to the field of water cup technology, and in particular to a press-fit cup lid and a water cup. Background Technology

[0002] The lid is the main component of a water cup, used to seal the mouth of the cup. Traditional water cups require the entire lid to be removed from the body to pour out the liquid, which is inconvenient. Push-button lids are currently the most commonly used type.

[0003] Existing patents also disclose various types of press-type cup lids with different structures. For example, Chinese patent application number 202411129035.5 discloses a press-type ring-shaped water-dispensing cup lid; Chinese patent application number 202420681820.0 discloses an inner plug for a press-type water-dispensing thermos cup; Chinese patent application number 202421110489.3 discloses a cup lid that dispenses water after pressing; and Chinese patent application number 202421466021.8 discloses a press-opening cup lid and its cup. The press-type cup lids disclosed in these existing patent documents have complex structures, many parts, complicated assembly steps, and high production costs.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a press-fit cup lid and a water cup.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A press-type cup lid includes a lid body, a press-type water outlet plug, an elastic reset component, a locking rod, and an inner core. The top surface of the lid body has a cavity, a press hole, and a water passage hole coaxially arranged from top to bottom. A blocking step is formed at the junction of the press hole and the water passage hole. The inner core is disposed within the lid body and located within the water passage hole. A central hole is formed in the center of the inner core. Two symmetrical circulation guide locking channels are arranged on the inner sidewall of the central hole, each with an open locking position and a closed position. The press-type water outlet plug includes a press part extending into the cavity through the press hole, a limiting ring disposed on the bottom edge of the press part, a sealing ring sleeved on the outer sidewall of the press part and tightly connected to the top surface of the limiting ring, and a central post disposed in the center of the bottom surface of the press part and extending into the central hole. The central post has a radially arranged waist-shaped movable part. The locking rod passes through the waist-shaped movable hole and is movably positioned within it. Both ends of the locking rod extend into two circulating guide locking channels, and the locking rod is movably positioned within these channels. A limiting ring and a sealing ring are located within the water passage hole. An elastic reset element is elastically clamped between the bottom surface of the pressing part and the top surface of the inner core. The elastic reset element applies an outward elastic force to the pressing part. A water outlet gap exists between the outer wall of the pressing part and the inner wall of the pressing hole. When the locking rod is in the closed position, the elastic reset element is in an extended state, the sealing ring on the pressing part is tightly fitted with the blocking step, and the water outlet gap is not connected to the water passage hole. When the locking rod is locked in the open position, the elastic reset element is in a compressed state, the sealing ring on the pressing part separates from the blocking step, and the water outlet gap communicates with the water passage hole.

[0008] Furthermore, the outer wall of the inner core is fixedly connected to the inner wall of the water passage via multiple connecting plates.

[0009] Furthermore, the top surface of the inner core is recessed with an annular guide hole, and the central hole is located inside the annular guide hole. The water outlet plug also includes a guide sleeve disposed on the bottom surface of the pressing part, with the central column located inside the guide sleeve, and the guide sleeve slidingly engaging with the annular guide hole.

[0010] Furthermore, a cavity is formed between the outer wall of the central column and the inner wall of the guide sleeve, and the elastic reset element is located within the cavity.

[0011] Furthermore, the central column is detachably connected to the pressing part.

[0012] Furthermore, the inner wall of the central hole is slidably connected to the central column via a guide structure; the guide structure includes a guide groove and a guide block, the inner wall of the guide groove is slidably connected to the guide block; the inner wall of the central hole is provided with a guide groove and / or a guide block, and correspondingly, the outer wall of the central column is provided with a guide block and / or a guide groove.

[0013] Furthermore, the cyclic guide locking channel includes a closing channel, a cyclic movement trajectory cavity communicating with the closing channel, and a guide ramp located in the middle of the cyclic movement trajectory cavity. The outer side wall of the guide ramp and the inner side wall of the cyclic movement trajectory cavity form a press-down trajectory channel, an opening channel, and a press-up trajectory channel that are connected in sequence. The opening locking position is located on the lower side of the guide ramp and is located in the opening channel. The closing position is located in the closing channel. The locking rod can enter the press-down trajectory channel along the closing channel. The locking rod can enter the opening locking position of the opening channel along the press-down trajectory channel. The locking rod can move from the opening locking position to the press-up trajectory channel. The locking rod can move along the press-up trajectory channel to the closing channel.

[0014] Furthermore, the outer wall of the cover is provided with a limiting step, a sealing groove and an external thread from top to bottom, and a sealing ring is embedded in the sealing groove.

[0015] This utility model also provides a water cup, including a cup body and the aforementioned press-fit lid, the press-fit lid being detachably mounted on the mouth of the cup body.

[0016] Furthermore, a temperature control display screen is installed in the middle of the cup body, and a temperature control system is installed at the bottom of the cup body. The temperature control display screen is electrically connected to the temperature control system.

[0017] The beneficial effects of this utility model are as follows: In practical applications, when the press-fit cup lid is installed on the mouth of the cup body, under normal conditions, the locking rod is located in the closed position of the circulation guide locking channel. At this time, the elastic reset member is in the extended state and applies an upward elastic force to the press-fit water plug, so that the limiting ring of the press-fit water plug presses the sealing ring tightly onto the blocking step, thereby making the sealing ring and the blocking step fit tightly together and play a sealing role. The water outlet gap is not connected to the water passage hole, so the liquid in the cup body cannot be poured out. When it is necessary to pour out the liquid in the cup, apply downward pressure to the pressing part of the water outlet plug, causing the water outlet plug to move downward and compress the elastic reset member. During the downward movement of the water outlet plug, the end of the locking rod moves downward along the circulation guide locking channel. After releasing the pressing pressure, the water outlet plug will move slightly upward under the rebound force of the elastic reset member, so that the locking rod is locked in the open locking position. At this time, the sealing ring separates from the blocking step and creates a communication gap. The water outlet gap communicates with the water inlet through this communication gap, so that the liquid in the cup can be poured out into the concave cavity through the water inlet, the communication gap and the water outlet gap. The liquid in the concave cavity is for the user to drink. When the pressing part of the water outlet plug is pressed again, the locking rod will disengage from the open position and move upward along the circulation guide locking channel to the closed position under the rebound force of the elastic reset element, so that the sealing ring is in tight contact with the blocking step, and the liquid in the cup cannot be poured out; thus achieving the purpose of opening the water outlet plug with one press and closing the water outlet plug with another press; in particular, during the process of the locking rod moving up and down along the circulation guide locking channel, the locking rod can move adaptively within the waist-shaped movable hole. This press-button cup lid and cup use a circulating guide channel to guide the lifting and lowering movement of the locking rod. The circulating guide channel includes a closed position and an open position that cooperate with the locking rod to facilitate switching between open and closed states. It is easy to operate, has a simple structure, reduces the number of parts, simplifies assembly steps, and lowers production costs. The top surface of the lid has a recessed cavity, which is aesthetically pleasing and prevents liquid from easily overflowing. It also buffers spilled liquid, allowing for a more comfortable drinking experience. Furthermore, when the water outlet is in the closed position, external liquids can be poured into the recessed cavity, or items (such as fruit) can be placed inside. The recessed cavity serves as a container for liquids or items, functioning as a cup or other container. Attached Figure Description

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0031] like Figures 1 to 10As shown, this utility model provides a press-type cup lid, which includes a lid body 1, a press-type water outlet plug 2, an elastic reset member 3, a locking rod 4, and an inner core 5. The top surface of the lid body 1 is coaxially provided with a cavity 6, a press hole 7, and a water passage hole 8 from top to bottom. A blocking step 9 is formed at the junction of the press hole 7 and the water passage hole 8. The inner core 5 is disposed inside the lid body 1 and located inside the water passage hole 8. A central hole 10 is opened in the middle of the inner core 5. Two circulation guide locking channels are symmetrically arranged on the inner side wall of the central hole 10. 11. The circulating guide locking channel 11 is provided with an open locking position 12 and a closed position 13. The press-out water plug 2 includes a pressing part 14 extending into the recessed cavity 6 through the pressing hole 7, a limiting ring 15 disposed on the bottom edge of the pressing part 14, a sealing ring 16 sleeved on the outer wall of the pressing part 14 and tightly connected to the top surface of the limiting ring 15, and a central column 17 disposed in the middle of the bottom surface of the pressing part 14 and extending into the central hole 10. The central column 17 has a waist-shaped movable hole 18 radially opened. The movable hole 18 penetrates the side wall of the central column 17. The locking rod 4 penetrates the waist-shaped movable hole 18 and is movably disposed within the waist-shaped movable hole 18. The two ends of the locking rod 4 extend into the two circulating guide locking channels 11 respectively. The locking rod 4 is movably disposed within the circulating guide locking channels 11. The limiting ring 15 and the sealing ring 16 are located within the water passage hole 8. The elastic reset member 3 is elastically clamped between the bottom surface of the pressing part 14 and the top surface of the inner core 5. The elastic reset member 3 is used to apply outward elastic force to the pressing part 14. The outer wall of the pressing part 14 and the inner wall of the pressing hole 7 have a water outlet gap 19; when the locking rod 4 is in the closed position 13, the elastic reset member 3 is in the extended state, the sealing ring 16 on the pressing part 14 is tightly fitted with the blocking step 9, and the water outlet gap 19 is not connected to the water passage hole 8; when the locking rod 4 is locked in the open locking position 12, the elastic reset member 3 is in the compressed state, the sealing ring 16 on the pressing part 14 is separated from the blocking step 9, and the water outlet gap 19 is connected to the water passage hole 8.

[0032] In practical applications, the press-fit cup lid is installed on the cup mouth of the cup body 42. Under normal conditions, the locking rod 4 is located at the closed position 13 of the circulation guide locking channel 11. At this time, the elastic reset member 3 is in the extended state and applies an upward elastic force to the press-fit water plug 2, so that the limiting ring 15 of the press-fit water plug 2 presses the sealing ring 16 tightly onto the blocking step 9, thereby making the sealing ring 16 and the blocking step 9 fit tightly together and play a sealing role. The water outlet gap 19 is not connected to the water passage hole 8, so the liquid in the cup body 42 cannot be poured out. When it is necessary to pour out the liquid in the cup body 42, a downward pressing force is applied to the pressing part 14 of the pressing plug 2, causing the pressing plug 2 to move downward and compress the elastic reset member 3. During the downward movement of the pressing plug 2, the end of the locking rod 4 moves downward along the circulation guide locking channel 11. After releasing the pressing force, the pressing plug 2 moves slightly upward under the rebound force of the elastic reset member 3, so that the locking rod 4 is locked at the open locking position 12. At this time, the sealing ring 16 separates from the blocking step 9 and creates a communication gap. The water outlet gap 19 communicates with the water passage hole 8 through the communication gap, so that the liquid in the cup body 42 can be poured out into the concave cavity 6 through the water passage hole 8, the communication gap and the water outlet gap 19. The liquid in the concave cavity 6 is for the user to drink. When the pressing part 14 of the water outlet plug 2 is pressed again, the locking rod 4 will disengage from the opening locking position 12 and move upward along the circulation guide locking channel 11 to the closing position 13 under the action of the elastic reset member 3, so that the sealing ring 16 is in close contact with the blocking step 9, and the liquid in the cup body 42 cannot be poured out; thus achieving the purpose of opening the water outlet plug 2 with one press and closing it with another press; wherein, during the process of the locking rod 4 moving up and down along the circulation guide locking channel 11, the locking rod 4 can adaptively move within the waist-shaped movable hole 18. This press-fit cup lid guides the lifting and lowering movement of the locking rod 4 through the circulating guide locking channel 11. A closed position 13 and an open position 12 are provided within the circulating guide locking channel 11 to cooperate with the locking rod 4, facilitating switching between open and closed states. It is easy to operate, has a simple structure, reduces the number of parts, simplifies assembly steps, and lowers production costs. Furthermore, the top surface of the lid 1 has a recessed cavity 6, which is aesthetically pleasing and prevents liquid from easily overflowing. It also buffers spilled liquid, allowing it to be drunk more smoothly. Additionally, when the press-fit water outlet plug 2 is in the closed state, external liquids can be poured into the recessed cavity 6, or items (such as fruit) can be placed inside. The recessed cavity 6 serves as a container for holding liquids or items, functioning as a cup or container.

[0033] In this embodiment, the inner core 5 is coaxially arranged with the cover 1, and the outer side wall of the inner core 5 is fixedly connected to the inner side wall of the water passage 8 via multiple connecting plates 20. This structural design facilitates the fixed installation of the inner core 5 inside the cover 1 and allows for a suitable distance between the outer side wall of the inner core 5 and the inner wall of the cover 1.

[0034] Specifically, multiple connecting plates 20 are arranged in a ring array around the central axis of the inner core 5, so that the force between the inner core 5 and the cover 1 is uniform and the connection is firm.

[0035] Specifically, the cover 1, connecting plate 20 and inner core 5 are an integral structure with good structural stability, high strength and hardness.

[0036] In this embodiment, the top surface of the inner core 5 is recessed with an annular guide hole 21, and the central hole 10 is located within the annular guide hole 21. The press-to-discharge plug 2 also includes a guide sleeve 22 disposed on the bottom surface of the pressing part 14, with the central post 17 located within the guide sleeve 22. The guide sleeve 22 is slidably engaged with the annular guide hole 21. During the lifting and lowering process of the press-to-discharge plug 2, the guide sleeve 22 and the annular guide hole 21 are slidably engaged, which improves the lifting and lowering stability of the press-to-discharge plug 2, and the guide sleeve 22 plays a guiding and limiting role for the elastic reset member 3.

[0037] In this embodiment, a cavity 23 is formed between the outer wall of the central column 17 and the inner wall of the guide sleeve 22. The elastic reset member 3 is located in the cavity 23, which makes the structure of the central column 17, the elastic reset member 3 and the guide sleeve 22 compact. The central column 17 and the guide sleeve 22 play a guiding and limiting role for the elastic reset member 3, which improves the working stability of the elastic reset member 3.

[0038] In this embodiment, the central column 17 and the pressing part 14 are detachably connected. This structural design enables modular assembly of the central column 17 and the pressing part 14, facilitating the disassembly, assembly, and maintenance of the central column 17 and the locking rod 4.

[0039] Specifically, the bottom surface of the pressing part 14 has a downward-protruding connecting post 24. The central post 17 has a connecting hole 25, a through hole 26, and a mounting hole 27 arranged coaxially from top to bottom. The connecting post 24 extends into the connecting hole 25. The connecting post 24 has a threaded hole 28 communicating with the through hole 26. A bolt 29 is threadedly connected to the threaded hole 28. The bolt 29's shank passes through the through hole 26, and the bolt 29's nut is located in the mounting hole 27. The bolt 29 locks the central post 17 and the connecting post 24 together. A waist-shaped movable hole 18 radially passes through the mounting hole 27. During disassembly and assembly, a screwdriver can be inserted into the mounting hole 27 to tighten or loosen the bolt 29.

[0040] Specifically, a positioning block is provided on the peripheral side wall of the connecting column 24, and a positioning groove 44 is recessed on the inner side wall of the connecting hole 25. The positioning block and the positioning groove 44 are matched in a concave-convex manner. The positioning block and the positioning groove 44 cooperate to improve the positional accuracy and stability of the assembly of the pressing part 14 and the central column 17.

[0041] In this embodiment, the inner wall of the central hole 10 and the central column 17 are slidably connected via a guide structure. Specifically, the guide structure includes a guide groove 30 and a guide block 31, with the inner wall of the guide groove 30 slidably connected to the guide block 31; the inner wall of the central hole 10 is provided with the guide groove 30 and / or the guide block 31, and correspondingly, the outer wall of the central column 17 is provided with the guide block 31 and / or the guide groove 30. During the lifting and lowering of the water outlet plug 2, the guide groove 30 and / or the guide block 31 on the central column 17 slides in conjunction with the guide block 31 and / or the guide groove 30 in the central hole 10, further improving the stability of the lifting and lowering of the water outlet plug 2. By blocking and limiting the outer wall of the guide block 31 through the inner wall of the guide groove 30, the central column 17 can be prevented from rotating or swaying loosely relative to the central hole 10, thereby preventing the water outlet plug 2 from rotating or swaying loosely relative to the pressing hole 7.

[0042] In this embodiment, the cyclic guide locking channel 11 includes a closing channel 32, a cyclic movement trajectory cavity communicating with the closing channel 32, and a guide ramp 33 disposed in the middle of the cyclic movement trajectory cavity. The outer side wall of the guide ramp 33 and the inner side wall of the cyclic movement trajectory cavity form a press-down trajectory channel 34, an opening channel 35, and a press-up trajectory channel 36 that are connected in sequence. The opening locking position 12 is disposed on the lower side of the guide ramp 33 and located in the opening channel 35. The closing position 13 is located in the closing channel 32. The locking rod 4 can enter the press-down trajectory channel 34 along the closing channel 32. The locking rod 4 can enter the opening locking position 12 of the opening channel 35 along the press-down trajectory channel 34. The locking rod 4 can move from the opening locking position 12 to the press-up trajectory channel 36. The locking rod 4 can move along the press-up trajectory channel 36 to the closing channel 32.

[0043] Initially, the locking lever 4 is in the closed position 13, and the water outlet plug 2 is in the closed state. At this time, pressing the water outlet plug 2 once moves the water outlet plug 2 and the locking lever 4 from the closed channel 32 to the pressing downward trajectory channel 34. The locking lever 4 moves along the pressing downward trajectory channel 34 to the opening locking position 12 in the opening channel 35, so that the water outlet plug 2 switches to the open state. Then, pressing the water outlet plug 2 once more causes the water outlet plug 2 and the locking lever 4 to descend and disengage from the opening locking position 12. Under the rebound force of the elastic reset member 3, the water outlet plug 2 and the locking lever 4 move along the pressing upward trajectory channel 36 to the closed position 13 of the closed channel 32, so that the water outlet plug 2 switches to the closed state.

[0044] In this embodiment, the outer side wall of the lid 1 is provided with a limiting step 37, a sealing groove 38, and an external thread 39 from top to bottom. A sealing ring 40 is embedded in the sealing groove 38. When the lid 1 is installed on the mouth of the cup body 42, the external thread 39 is threadedly connected to the internal thread of the mouth of the cup body 42, the sealing ring 40 seals the gap between the lid 1 and the mouth of the cup body 42, and the limiting step 37 abuts against the end face of the mouth of the cup body 42, ensuring the positional accuracy and stability of the lid 1 installed on the cup body 42.

[0045] In this embodiment, the elastic reset element 3 is a spring, which is sleeved outside the central post 17. The central post 17 and the guide sleeve 22 guide and limit the spring, improving the working stability of the spring.

[0046] Specifically, the top surface of the pressing part 14 is provided with an upwardly arched arc surface that extends into the recessed cavity 6. This structural design is aesthetically pleasing and facilitates easy and comfortable application of downward pressing force to the pressing part 14 by the user.

[0047] Specifically, the inner core 5 has a through hole 41 that communicates with the central hole 10 and the annular guide hole 21. This structural design allows the inner core 5 to communicate with the water passage hole 8. Even if there is liquid or water droplets inside the inner core 5, it will be discharged through the through hole 41, reducing the problem of liquid stagnation in the central hole 10 and the annular guide hole 21 of the inner core 5, which could lead to bacterial growth or mold.

[0048] This utility model also provides a water cup, including a cup body 42 and the aforementioned press-fit lid, the press-fit lid being detachably mounted on the rim of the cup body 42. This water cup possesses all the beneficial effects of the press-fit lid, which will not be elaborated further here.

[0049] In this embodiment, a temperature control display screen 43 is provided in the middle of the cup body 42, and a temperature control system is provided at the bottom of the cup body 42. The temperature control display screen 43 is electrically connected to the temperature control system. The temperature control display screen 43 can display the current temperature and adjust the temperature value. The temperature control system cools, heats, or keeps the liquid in the cup body 42 warm according to the temperature value adjusted by the temperature control display screen 43. Specifically, the temperature control system can adopt a temperature electronic control system of existing technology, which will not be described in detail here.

[0050] All technical features in this embodiment can be freely combined according to actual needs.

[0051] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
