Description

Technical Field

[0001] This utility model relates to the field of water cup technology, specifically to a threadless cup lid and a water cup thereof. Background Technology

[0002] In today's daily life, cups are widely used beverage containers, and the cup lid, as an important component of the cup, directly affects the user's experience and health. Currently, the vast majority of cups on the market are equipped with threaded lids; however, these traditional threaded lids have gradually revealed many problems that cannot be ignored during long-term use.

[0003] From a hygiene and health perspective, the spiral structure of a threaded cup lid creates complex gaps and grooves, making these areas ideal breeding grounds for dirt and bacteria. In daily life, cups inevitably come into contact with various impurities, such as dust floating in the air and food residue particles. These tiny substances can easily accumulate and remain in the fine gaps of the threads. After the cup is used to hold various beverages, the liquid remaining in the threads, due to its difficulty in thorough cleaning, provides an ideal environment for bacterial growth under suitable temperature and humidity conditions. For example, harmful bacteria such as E. coli and Staphylococcus aureus may grow. When users unknowingly drink from the cup again, these bacteria may enter the human body, posing a potential threat to the digestive and immune systems, causing gastrointestinal discomfort symptoms such as abdominal pain, diarrhea, and vomiting, seriously affecting health.

[0004] In terms of practical convenience, screw-top cup lids also cause inconvenience for many people. Children, who are still developing, have relatively weak hand muscles and their fine motor skills are not yet fully mature. Opening or closing a screw-top lid often requires considerable effort to rotate, making it a difficult operation for them. This can even lead to difficulty drinking, especially when children are thirsty and urgently need water, causing unnecessary disruption to their daily lives and healthy development. Similarly, as the elderly age, their physical functions gradually decline, their hand muscle strength decreases significantly, and the flexibility of their hand joints diminishes, making it increasingly difficult to operate screw-top cup lids. This not only reduces the convenience of using the cup but may also affect their ability to live independently, causing numerous inconveniences and annoyances in daily life. Furthermore, for people with hand disabilities or injuries, rotating a screw-top cup lid becomes an almost impossible task due to their limited hand function, creating significant obstacles to using the cup and severely restricting its normal use, thus negatively impacting their daily lives.

[0005] From the perspective of the lifespan and sealing stability of the cup lid, threaded connections have inherent defects. During frequent opening and closing, friction between the threads is unavoidable. This continuous friction gradually wears down the thread profile, causing changes in dimensional accuracy and surface roughness. With increased use, thread wear intensifies, leading to a decrease in the tightness of the fit between the lid and the cup, severely impacting the sealing performance and resulting in frequent leaks. This not only wastes beverages but can also cause liquid to seep into the surrounding environment, wetting the user's clothes, tabletops, or other items, causing considerable inconvenience and distress. Furthermore, once the threads wear to a certain extent, their original performance often cannot be restored through simple repairs, usually requiring the replacement of the entire lid. This undoubtedly increases the user's financial cost while also wasting resources and creating environmental pressure.

[0006] In summary, traditional threaded cup lids have a series of problems in terms of hygiene, ease of use, sealing performance, and service life, which urgently require an innovative cup lid structure to solve. Summary of the Invention

[0007] This utility model provides a threadless cup lid and its water cup to overcome the defects of traditional threaded cup lids.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A threadless cup lid includes a cup lid, a push-button switch, a telescopic mechanism, and a sealing silicone sleeve. The push-button switch is connected to the telescopic mechanism via a transmission mechanism. One end of the telescopic mechanism is connected to the transmission mechanism, and the other end is connected to the sealing silicone sleeve. The sealing silicone sleeve is located at the bottom of the cup lid and is used to seal or open the cup opening. When sealing the cup, the telescopic mechanism compresses and deforms the sealing silicone sleeve, making the diameter of the sealing silicone sleeve inside the cup larger than the diameter of the cup opening, so that the sealing silicone sleeve fits tightly against the inner wall of the cup. When opening the cup, the push-button switch is pressed inward, and the transmission mechanism drives the telescopic mechanism to move downward and release the sealing silicone sleeve, so that the diameter of the sealing silicone sleeve inside the cup is smaller than the diameter of the cup opening, thereby opening the cup's spout.

[0010] Preferably, the telescopic assembly includes a valve seat, a valve stem, and a first compression spring. The sealing silicone sleeve is installed at the bottom of the cup lid through the valve seat. The valve seat has a valve stem and a first compression spring. The valve seat has a mounting hole in the middle. The upper end of the valve stem passes through the mounting hole and is movably connected to the transmission assembly. The upper end of the valve stem has a spring limiting member. The first compression spring is sleeved on the valve stem, with one end abutting against the valve seat and the other end abutting against the spring limiting member. The lower end of the valve stem has a pressing plate. The sealing silicone sleeve is a cylindrical shape with open ends. One end of the sealing silicone sleeve is connected and fixed to the outer wall of the valve seat, and the other end is connected and fixed to the pressing plate. Under the elastic force of the first compression spring, the valve stem can drive the pressing plate to compress and deform the sealing silicone sleeve.

[0011] Preferably, the valve stem is further provided with an exhaust assembly, which includes an exhaust rod, an exhaust plug, and a second compression spring. An exhaust channel is provided through the middle of the valve stem, and the exhaust rod is inserted into the exhaust channel. One end of the exhaust rod is movably connected to a transmission assembly, and the other end is fixedly connected to the exhaust plug. A first limiting ring is provided at the lower end of the exhaust rod, and an annular stop is provided at the end of the exhaust channel. One end of the second compression spring abuts against the annular stop, and the other end abuts against the first limiting ring. Under the elastic force of the second compression spring, the exhaust rod can drive the exhaust plug to close the exhaust channel.

[0012] Preferably, the upper end of the exhaust rod is further provided with a second limiting ring, and both the first limiting ring and the second limiting ring are provided with exhaust notches.

[0013] Preferably, the transmission mechanism includes a sliding member and a sliding mounting base. The sliding mounting base is disposed inside the cup lid, and the push switch is disposed on one side of the sliding mounting base. A sliding inclined surface is provided on the side of the push switch facing the sliding mounting base. The sliding member is slidably mounted inside the sliding mounting base and is movably connected to the telescopic mechanism. The sliding member has a sliding inclined block on the side corresponding to the position of the push switch. A sliding channel is provided perpendicularly on the side wall of the sliding mounting base corresponding to the position of the sliding inclined block. The sliding inclined block extends outward through the sliding channel and cooperates with the sliding inclined surface. When the push switch is pressed inward, the sliding inclined block of the sliding member slides and displaces along the sliding inclined surface and drives the sliding member to move downward along the sliding channel, and drives the telescopic mechanism movably connected to the sliding member to move downward synchronously.

[0014] Preferably, a self-locking component is further provided between the sliding member and the telescopic mechanism to lock the push switch in the open state. The self-locking component includes a rotating member. The sliding member has a central hole in its middle. The upper end of the rotating member is fitted into the central hole of the sliding member. The rotating member can rotate relative to the sliding member. The inner sidewall of the sliding mounting base is uniformly provided with vertical limiting protrusions. A vertical sliding groove is formed between adjacent limiting protrusions. A first sliding block matching the sliding groove is provided on the periphery of the sliding member at the position corresponding to the sliding groove. A second sliding block matching the sliding groove is provided on the periphery of the rotating member at the position corresponding to the sliding groove. The first and second sliding blocks move up and down along the sliding groove. The lower end face of the sliding member is provided with a ratchet. The upper end face of the second sliding block is provided with a first guide slope. The ratchet is provided with a second guide slope that is inclined to both sides. The first guide slope matches the second guide slope. The lower end face of the limiting protrusion is provided with a limiting groove and a limiting block. The lower end face of the limiting groove is provided with a third guide slope. The lower end face of the limiting block is provided with a fourth guide slope.

[0015] Preferably, the cup lid is symmetrically provided with two push-button switches, and a switch locking assembly is movably provided between the two push-button switches. The switch locking assembly includes a groove formed on the top of the cup lid and a locking button slidably disposed in the groove. One end of the groove is a locking end, and the other end is an unlocking end. The locking button is connected to a locking slider inside the cup lid. The locking slider includes a horizontally arranged limiting rod and a guide rod horizontally arranged in the middle of the limiting rod. The push-button switches have limiting protrusions at positions corresponding to the limiting rods. The cup lid has a guide rail at positions corresponding to the guide rods, and the guide rod slides along the direction of the guide rails. When it is necessary to lock the push-button switches, the locking button is pushed to the locking end along the direction of the groove locking end, so that the two ends of the limiting rod abut against the limiting protrusions of the two push-button switches respectively, so that the two push-button switches cannot be pressed inward. When it is necessary to unlock the push-button switches, the locking button is pushed to the unlocking end along the direction of the groove unlocking end, and the limiting rod and the limiting protrusions of the two push-button switches are misaligned, so that the push-button switches can move inward.

[0016] Preferably, the cup lid is provided with a sliding locking assembly, which includes a transverse opening on the side wall of the cup lid and a slidable protruding button disposed in the transverse opening. One end of the transverse opening is a locking end, and the other end is an unlocking end. The cup lid is rotatably fitted with a rotating ring around the sliding mounting base, and the rotating ring is connected to the protruding button. The rotating ring extends inward to a stop block below the sliding ramp of the slider. When it is necessary to lock the slider, the protruding button is pushed to the locking end along the direction of the locking end of the transverse opening. The protruding button drives the rotating block connected to it to rotate around the sliding mounting base, so that the stop block is moved to the bottom of the sliding ramp of the slider and abuts against it, so that the sliding ramp of the slider cannot move downward along the sliding channel. When it is necessary to unlock the slider, the protruding button is pushed to the unlocking end along the direction of the unlocking end of the transverse opening. The protruding button drives the rotating block connected to it to rotate around the sliding mounting base, so that the stop block is moved to a position that is misaligned with the sliding ramp of the slider, so that the sliding ramp of the slider can move downward along the sliding channel.

[0017] Preferably, the sliding mounting base has a limiting protrusion on the outer side wall connected to the rotating ring, the inner side wall of the rotating ring has a first positioning groove corresponding to the limiting protrusion, a second positioning groove is provided on one side of the first positioning groove, the first positioning groove and the second positioning groove are interconnected and have a transition part.

[0018] A water cup includes a cup body and a threadless lid as described in any of the above claims, the threadless lid being detachably connected to the cup body; the diameter of the cup opening is smaller than the diameter of the cup body; when the cup body needs to be sealed, a telescopic component deforms a sealing silicone sleeve, making the diameter of the sealing silicone sleeve inside the cup body larger than the diameter of the cup opening, so that the sealing silicone sleeve fits tightly against the inner wall of the cup body to achieve an interference fit; when the cup body needs to be opened, a push-button switch is pressed inward, and a transmission mechanism drives the telescopic component to move downward to release the sealing silicone sleeve, so that the diameter of the sealing silicone sleeve inside the cup body is smaller than the diameter of the cup opening, thereby opening the water cup.

[0019] Compared with existing technologies, the advantages of this invention are that it abandons the traditional threaded connection and uses a combination of a push-button switch, a transmission mechanism, a telescopic mechanism, and a sealing silicone sleeve to connect the lid and the cup body. There are no threaded gaps, reducing bacterial attachment points. The sealing silicone sleeve fits tightly to the cup body and is easy to clean, effectively preventing dirt accumulation and bacterial growth. At the same time, the push-button operation is effortless; compared to traditional threaded rotation, children, the elderly, and those with hand disabilities can easily open and close the lid by pressing the switch with minimal force. The transmission mechanism causes the telescopic component to move the sealing silicone sleeve, allowing for easy opening and closing. Regarding sealing performance and lifespan, the telescopic mechanism's compression and release mechanism replaces threaded friction, ensuring a stable interference fit of the silicone sleeve with each seal, maintaining good sealing performance, preventing leakage, reducing beverage waste and item soaking, and eliminating thread wear, thus extending the lifespan of the lid.

[0034] Please see Figure 1-11 As shown, a threadless cup lid includes a cup lid 1, a push-button switch 2 disposed on the cup lid 1, a telescopic mechanism, and a sealing silicone sleeve 3. The push-button switch 2 is connected to the telescopic mechanism via a transmission mechanism. One end of the telescopic mechanism is connected to the transmission mechanism, and the other end is connected to the sealing silicone sleeve 3. The sealing silicone sleeve 3 is disposed at the bottom of the cup lid 1 for sealing or opening the mouth of the cup body 4. Figure 10As shown, when the cup body 4 needs to be sealed, the telescopic component compresses and deforms the sealing silicone sleeve 3, making the diameter of the sealing silicone sleeve 3 inside the cup body 4 larger than the diameter of the cup opening, so that the silicone sleeve tightly fits the inner wall of the cup body 4 to achieve an interference fit; as shown Figure 11 As shown, when it is necessary to open the cup body 4, press the push switch 2 inward. The transmission mechanism drives the telescopic component to move downward, releasing the sealing silicone sleeve 3. This makes the diameter of the sealing silicone sleeve 3 inside the cup body 4 smaller than the diameter of the cup opening, thus opening the water outlet of the cup body 4. Compared with the prior art, the beneficial effects of this utility model are that it abandons the traditional threaded form and uses a combination of push switch 2, transmission mechanism, telescopic mechanism and sealing silicone sleeve 3 to connect the cup lid 1 and the cup body 4. There are no thread gaps, reducing bacterial attachment points. The sealing silicone sleeve 3 fits tightly to the cup body 4 and is easy to clean, effectively preventing dirt accumulation and bacterial growth. At the same time, the pressing operation is labor-saving. Compared with the traditional threaded rotation, children, the elderly and those with hand inconvenience can easily open and close the cup lid 1 by pressing the switch 2 with less force, which drives the telescopic component to move the sealing silicone sleeve 3. In terms of sealing performance and lifespan, the compression and release mechanism of the telescopic mechanism on the sealing silicone sleeve 3 replaces the thread friction, ensuring a stable interference fit of the sealing silicone sleeve 3 every time it is sealed, maintaining good sealing performance, avoiding water leakage, reducing beverage waste and item soaking, while eliminating thread wear and extending the service life of the cup lid 1. Specific Implementation Example 1:

[0036] like Figures 1 to 2 As shown, the telescopic assembly includes a valve seat 5, a valve stem 6, and a first compression spring 7. The sealing silicone sleeve 3 is installed at the bottom of the cup lid 1 through the valve seat 5. The valve seat 5 is provided with the valve stem 6 and the first compression spring 7. The valve seat 5 has a mounting hole in the middle. The upper end of the valve stem 6 passes through the mounting hole and is movably connected to the bottom of the rotating part 23. The upper end of the valve stem 6 is provided with a spring limiting member 8. The first compression spring 7 is sleeved on the valve stem 6, with one end abutting against the valve seat 5 and the other end abutting against the spring limiting member 8. The lower end of the valve stem 6 is provided with a pressing plate 9. The sealing silicone sleeve 3 is a cylindrical shape with open ends. One end of the sealing silicone sleeve 3 is connected and fixed to the outer wall of the valve seat 5, and the other end is connected and fixed to the pressing plate 9. Under the elastic force of the first compression spring 7, the valve stem 6 can drive the pressing plate 9 to compress and deform the sealing silicone sleeve 3.

[0037] When it is necessary to seal the cup body 4, place the cup lid 1 stably on the cup body 4. Under the action of its own elastic force, the first compression spring 7 in the telescopic assembly pushes the valve stem 6 to drive the extrusion plate 9 to squeeze the sealing silicone sleeve 3, so that the diameter of the sealing silicone sleeve 3 inside the cup body 4 is larger than the diameter of the cup opening, thereby tightly fitting the inner wall of the cup body 4 to achieve an interference fit and achieve a good sealing effect.

[0038] When the cup body 4 needs to be opened, the user presses the push switch 2 inward. The sliding inclined surface 20 of the push switch 2 pushes the sliding block 21 of the slider 18 to slide along the sliding inclined surface 20, and drives the slider 18 to move downward along the sliding channel. This, in turn, drives the telescopic mechanism movably connected to the slider 18 to move downward synchronously. During this process, the telescopic mechanism releases the pressure on the sealing silicone sleeve 3, making the diameter of the sealing silicone sleeve 3 inside the cup body 4 smaller than the diameter of the cup opening, thus opening the spout of the cup body 4 and making it convenient for the user to take out the beverage inside. Specific Implementation Example 2:

[0040] like Figures 1 to 2 As shown, the valve stem 6 is also provided with an exhaust assembly, which includes an exhaust rod 10, an exhaust plug 11, and a second compression spring 12. An exhaust channel 13 is provided through the middle of the valve stem 6. The exhaust rod 10 passes through the exhaust channel 13. One end of the exhaust rod 10 is movably connected to the transmission assembly, and the other end is fixedly connected to the exhaust plug 11. A first limiting ring 14 is provided at the lower end of the exhaust rod 10. An annular baffle 15 is provided at the end of the exhaust channel 13. One end of the second compression spring 12 abuts against the annular baffle 15, and the other end abuts against the first limiting ring 14. Under the elastic force of the second compression spring 12, the exhaust rod 10 can drive the exhaust plug 11 to close the exhaust channel 13.

[0041] By incorporating a venting assembly, when the venting channel 13 is closed, pressing the switch 2 causes the venting rod 10 to move downwards via the transmission assembly, overcoming the elastic force of the second compression spring 12. This, in turn, causes the venting plug 11 at the end to open the venting channel 13, allowing pressure relief such as steam to escape. This prevents scalding of the user when the cup body 4 is opened. Conversely, the venting rod 10 can be moved upwards by the elastic force of the second compression spring 12, causing the venting plug 11 at the end to seal the venting channel 13, thus ensuring a seal within the cup body 4 and preventing liquid from leaking out of the venting channel 13. Specific Implementation Example 3:

[0043] like Figures 1 to 2As shown, to ensure the accuracy and stability of the vertical sliding of the exhaust rod 10 within the exhaust channel 13, a second limiting ring 16 is provided at the upper end of the exhaust rod 10. Through the coordinated action of the first limiting ring 14 and the second limiting ring 16, the exhaust rod 10 is effectively limited from both ends during its movement, strongly constraining the displacement direction of the exhaust rod 10 and ensuring that it remains vertical at all times, resolutely preventing deviation. This ensures the smoothness and reliability of the exhaust process and avoids problems such as poor exhaust or mechanical failure caused by the deviation of the exhaust rod 10. At the same time, to improve the exhaust effect of the exhaust channel 13, both the first limiting ring 14 and the second limiting ring 16 are provided with exhaust notches 17. In the actual exhaust process, steam or other gases can flow unimpeded within the exhaust channel 13 through these exhaust notches 17, greatly reducing the flow resistance of gas at the limiting rings, effectively preventing the accumulation and blockage of steam within the exhaust channel 13, ensuring that the exhaust channel 13 remains unobstructed at all times, and significantly enhancing the exhaust effect. Specific Implementation Example 4:

[0045] like Figures 1 to 4 As shown, the transmission mechanism includes a slider 18 and a sliding mounting base 19. The sliding mounting base 19 is disposed inside the cup lid 1. The push switch 2 is disposed on one side of the sliding mounting base 19. The side of the push switch 2 facing the sliding mounting base 19 has a sliding inclined surface 20. The slider 18 is slidably mounted inside the sliding mounting base 19 and is movably connected to the telescopic mechanism. The slider 18 has a sliding inclined block 21 on the side corresponding to the position of the push switch 2. The side wall of the sliding mounting base 19 has a sliding channel 22 perpendicularly provided at the position corresponding to the sliding inclined block 21. The sliding inclined block 21 extends outward through the sliding channel 22 and cooperates with the sliding inclined surface 20. When the push switch 2 is pressed inward, the slider 18... The sliding block 21 of the moving part 18 slides along the sliding inclined surface 20 and drives the sliding part 18 downward along the sliding channel 22, which in turn drives the sliding part 18 and the rotating part 23 downward. When the rotating part 23 moves downward, it pushes the lower valve seat 5 to overcome the elastic force of the first compression spring 7, thereby releasing the pressure on the sealing silicone sleeve 3. This makes the diameter of the sealing silicone sleeve 3 inside the cup body 4 smaller than the diameter of the cup opening, thus opening the spout of the cup body 4 and making it convenient for the user to take out the beverage. In the same process, it also pushes the lower vent rod 10 to overcome the elastic force of the second compression spring 12, thereby driving the vent plug 11 to open the vent channel 13 to release air. When it is necessary to seal the cup body 4, the opposite is true. Specific Implementation Example 5:

[0047] like Figures 1 to 4As shown, a self-locking component is provided between the sliding member 18 and the telescopic mechanism to lock the push switch 2 in the open state. The self-locking component includes a rotating member 23. The sliding member 18 has a central hole 24 in the middle. The upper end of the rotating member 23 is fitted into the central hole 24 of the sliding member 18. The rotating member 23 can rotate relative to the sliding member 18. The inner sidewall of the sliding mounting base 19 is uniformly provided with vertical limiting protrusions 25. Vertical sliding grooves 26 are formed between adjacent limiting protrusions 25. The periphery of the sliding member 18 is provided with a first sliding block 27 that matches the sliding groove 26. The periphery of the rotating member 23 is provided with a first sliding block 27 that matches the sliding groove 26. A second sliding block 28 matching the sliding groove 26 is provided at the position of the sliding groove 26. The first sliding block 27 and the second sliding block 28 move up and down along the sliding groove 26. The lower end face of the sliding member 18 is provided with a ratchet 29. The upper end face of the second sliding block 28 is provided with a first guide slope 30. The ratchet 29 is provided with a second guide slope 31 that is inclined to both sides. The first guide slope 30 matches the second guide slope 31. The lower end face of the limiting protrusion 25 is provided with a limiting groove 32 and a limiting block 33. The lower end face of the limiting groove 32 is provided with a third guide slope 34. The lower end face of the limiting block 33 is provided with a fourth guide slope 35.

[0048] If it is necessary to keep the cup body 4 open for a long time, the self-locking component can be operated. When the push switch 2 is pressed, causing the slider 18 to move downward within the sliding mounting base 19, the slider 18 drives the rotating member 23 to move downward along the sliding mounting base 19. The second guide slope 31 of the ratchet 29 on the lower end face of the slider 18 interacts with the first guide slope 30 on the upper end face of the second sliding block 28 of the rotating member 23. When the slider 18 drives the second sliding block 28 of the rotating member 23 to move downward until it disengages from the sliding groove 26, the second sliding block 28 engages between the ratchet 29, forcing the rotating member 23 to rotate relative to the slider 18. The second sliding block 28 of the rotating component 23 moves along the third guide slope 34 of the limiting groove 32 to the limiting groove 32 on the lower end face of the limiting protrusion 25 and is blocked by the limiting block 33, preventing it from disengaging from the limiting groove 32. This locks the rotating component 23 in its current position, thus limiting the rotating component 23. This prevents the valve stem 6, which abuts against the bottom of the rotating component 23, from being pushed by the first compression spring 7 under its own elastic force to drive the extrusion plate 9 to press the sealing silicone sleeve 3, thereby locking the position of the valve stem 6 and keeping the cup body 4 open. Simultaneously, the exhaust rod 10, which abuts against the bottom of the rotating component 23, is also unable to be pushed by the second compression spring 12 under its own elastic force to drive the exhaust plug 11 to close the exhaust channel 13, thus locking the position of the exhaust rod 10 and keeping the exhaust channel 13 open.

[0049] When it is necessary to reseal the cup body 4, the self-locking component can be operated. Pressing the press switch 2 causes the slider 18 to move downward within the sliding mounting base 19. Simultaneously, the slider 18 drives the rotating member 23 to move downward along the opposite side of the sliding mounting base 19. The second guide slope 31 of the ratchet 29 on the lower end face of the slider 18 interacts with the first guide slope 30 on the upper end face of the second sliding block 28 of the rotating member 23. At this time, the rotating member 23 is located within the limiting groove 32. When the slider 18 drives the second sliding block 28 of the rotating member 23 to move downward until it disengages from the limiting groove 32, the second sliding block 28 engages between the ratchet 29, forcing the rotating member 23 to reposition itself. The sliding member 18 rotates, causing the second sliding block 28 of the rotating member 23 to rotate and move to the limiting block 33 at the lower end of the limiting protrusion 25. It then slides back into the sliding groove 26 along the fourth guide slope 35 of the limiting block 33, causing the second sliding block 28 to gradually disengage from the limiting groove 32 and move upwards along the sliding groove 26 of the limiting protrusion 25 until it returns to its initial normal position. This allows the valve stem 6, which abuts against the bottom of the rotating member 23, to be pushed by the first compression spring 7 under its own elastic force, driving the extrusion plate 9 to press against the sealing silicone sleeve 3, thereby unlocking the valve stem 6 and maintaining the sealed state of the cup body 4. Simultaneously, the exhaust rod 10, which abuts against the bottom of the rotating member 23, can also be pushed by the second compression spring 12 under its own elastic force, driving the exhaust plug 11 to close the exhaust channel 13, thereby unlocking the exhaust rod 10 and keeping the exhaust channel 13 closed. Specific Implementation Example 6:

[0051] like Figures 5 to 6As shown, to prevent accidental pressing of the switch 2, the water bottle may be placed in a backpack, pocket, or other environment prone to compression during daily use. In this case, the switch locking component of the lid 1 plays a crucial role. By pushing the locking button 37 to the locking end, the limiting rod 38 tightly abuts against the limiting protrusions 40 of the two switches 2, preventing accidental pressing of the switches 2. For example, during outdoor activities, people may move their bodies frequently. Without the switch locking component, the lid 1 could easily open due to unintentional bumps or pressure, causing the drink to spill. This component effectively prevents this from happening, ensuring the water bottle's airtightness and safety during transport. Therefore, specifically, the cup lid 1 is symmetrically provided with two push switches 2, and the cup lid 1 is movably provided with a switch locking assembly between the two push switches 2. The switch locking assembly includes a slide groove 36 formed on the top of the cup lid 1 and a locking button 37 slidably disposed in the slide groove 36. One end of the slide groove 36 is a locking end, and the other end is an unlocking end. The locking button 37 is connected to a locking slider inside the cup lid 1. The locking slider includes a horizontally arranged limiting rod 38 and a guide rod 39 horizontally arranged in the middle of the limiting rod 38. The push switches 2 are provided with limiting protrusions 40 corresponding to the positions of the limiting rod 38. Figure 5 As shown, when it is necessary to lock the push switch 2, push the locking button 37 to the locking end along the direction of the locking end of the slide groove 36, so that the two ends of the limit rod 38 abut against the limit protrusions 40 of the two push switches 2 respectively, so that the two push switches 2 cannot be pressed inward; when it is necessary to unlock the push switch 2, push the locking button 37 to the unlock end along the direction of the unlocking end of the slide groove 36, so that the limit rod 38 and the limit protrusions 40 of the two push switches 2 are misaligned and separated, so that the push switch 2 can move inward.

[0052] like Figure 6 The cup lid 1 is provided with a guide rail 41 at the position corresponding to the guide rod 39. The guide rod 39 slides along the direction of the guide rail 41. When the locking button 37 moves the limiting rod 38, the guide rod 39 slides within the guide rail 41, strictly limiting the displacement path and range of the limiting rod 38. This ensures that the limiting rod 38 can accurately reach the predetermined position and achieve precise locking or unlocking with the limiting protrusion 40 of the press switch 2. This precise positioning mechanism effectively avoids problems such as locking failure or unsmooth unlocking due to rotational deviation, ensuring the reliability and stability of the operation of the cup lid 1. Specific Implementation Example 7:

[0054] like Figures 7 to 9As shown, in complex usage environments, such as outdoor travel, sports activities, or daily carrying, water bottles may be subjected to various external impacts and bumps. Therefore, the cup lid 1 is equipped with a sliding locking assembly. The sliding locking assembly includes a transverse opening 42 on the side wall of the cup lid 1 and a protruding button 43 slidably disposed in the transverse opening 42. One end of the transverse opening 42 is the locking end, and the other end is the unlocking end. The cup lid 1 is rotatably fitted with a rotating ring 44 around the sliding mounting base 19. The rotating ring 44 is connected to the protruding button 43. The rotating ring 44 extends inward to a stop block 55 below the sliding inclined block 21 of the slider 18. When it is necessary to lock the slider 18, the protruding button 43 is pushed to the locking end along the direction of the locking end of the transverse opening 42. The rotating ring 44 connected to it rotates around the sliding mounting base 19, so that the stop block 55 is displaced to the bottom of the sliding inclined block 21 of the slider 18 and abuts against the bottom of the sliding inclined block 21, so that the sliding inclined block 21 of the slider 18 cannot move downward along the sliding channel 22; when it is necessary to unlock the slider 18, the protruding button 43 is pushed to the unlocking end along the direction of the unlocking end of the transverse opening 42, and the protruding button 43 drives the rotating ring 44 connected to it to rotate around the sliding mounting base 19, so that the stop block 55 is displaced to the position of the sliding inclined block 21 of the slider 18 and separated, so that the sliding inclined block 21 of the slider 18 can move downward along the sliding channel 22.

[0055] like Figure 9 As shown, when it is necessary to lock the slider 18, push the protruding button 43 to the locking end. The rotating ring 44 connected to the pushing protruding button drives the stop block 55 to move below the sliding inclined block 21 of the slider 18, which obstructs the sliding inclined block 21 of the slider 18. This completely restricts the vertical displacement of the sliding inclined block 21, thereby ensuring that even if the cup lid 1 is subjected to external unexpected pressure or vibration, the slider 18 will not be displaced when the switch 2 is pressed when the cup lid 1 is not required to be opened. This effectively prevents the cup lid 1 from being accidentally opened due to misoperation, and greatly improves the stability and safety of the cup lid 1 in the closed state.

[0056] Similarly, when unlocking is required, simply push the protruding button 43 towards the unlocking end. The rotating ring 44 rotates simultaneously, causing the stop block 55 to move away from under the sliding ramp 21. This displaces the stop block and the sliding ramp 21, releasing the restriction on the sliding ramp 21. At this time, the slider 18 can move freely within the sliding channel 22, and the pressing switch 2 can normally drive the slider 18 and the subsequent telescopic mechanism to work, enabling the cup lid 1 to open smoothly. The entire unlocking operation is simple and easy to perform, requiring no complicated steps or tools, quickly meeting the user's need to take the beverage from the cup, and ensuring smooth operation.

[0057] Furthermore, the sliding mounting base 19 has a limiting protrusion 46 on its outer side wall connected to the rotating ring 44. The inner side wall of the rotating ring 44 has a first positioning groove 47 corresponding to the limiting protrusion 46, and a second positioning groove 48 on one side of the first positioning groove 47. The first positioning groove 47 and the second positioning groove 48 are interconnected and have a transition portion 49. During the operation of the sliding locking assembly, the limiting protrusion 46 on the outer side wall of the sliding mounting base 19 closely cooperates with the first positioning groove 47 on the inner side wall of the rotating ring 44, providing a precise positioning reference for the rotation of the rotating ring 44. When the protruding button 43 drives the rotating ring 44 to rotate, the limiting protrusion 46 slides within the first positioning groove 47, strictly limiting the rotation path and angle range of the rotating ring 44, ensuring that the stop block 55 can accurately reach the predetermined position and achieve precise locking or unlocking cooperation with the sliding inclined block 21 of the sliding member 18. This precise positioning mechanism effectively avoids problems such as locking failure or unsmooth unlocking due to rotational deviation, ensuring the reliability and stability of the cup lid 1 operation.

[0058] In summary, both the switch locking component and the sliding locking component can effectively control the opening function of the cup lid 1. The two can be used simultaneously to complement each other or selected according to the actual situation.

[0059] The switch locking assembly focuses on directly restricting the operation of the push-button switch 2. Through the sliding groove 3 on the top of the lid 1 and its corresponding locking button 37, locking slider, and other components, when in the locked state, its limiting rod 38 precisely abuts against the limiting protrusion 40 of the push-button switch 2, eliminating the possibility of the lid 1 accidentally opening due to accidental activation of the push-button switch 2. This plays a crucial role in scenarios such as placing the cup in a backpack, pocket, or during bumpy transportation, effectively ensuring the cup's airtightness, preventing beverage leakage, and greatly improving user safety and convenience.

[0060] The sliding locking assembly focuses on locking the key component of the transmission path—the slider 18. Utilizing the transverse opening 42 on the side wall of the lid 1, the protruding button 43, the rotatable rotating ring 44, and the stop block 55 thereon, when the protruding button 43 is pushed to the locking end, the stop block 55 accurately moves below the sliding ramp 21 of the slider 18 and firmly abuts against it, preventing the sliding ramp 21 from moving downwards along the sliding channel 22, thus cutting off the power transmission link between the push switch 2 and the telescopic mechanism. Similarly, when the cup is subjected to significant external impact, vibration, or in complex usage environments, it effectively prevents the lid 1 from opening due to unexpected factors, providing a reliable secondary guarantee for the closed state of the lid 1 and further enhancing the stability of the threadless lid 1 structure.

[0061] like Figure 7As shown, in order to facilitate user pressing, the surface of the press switch 2 is provided with friction protrusions, thereby increasing the friction force and making it easier for the user to operate and press; at the same time, the cup lid 1 is also provided with a handle for lifting the cup lid.

[0062] like Figure 10 and Figure 11 As shown, a water cup is also disclosed, including a cup body 4 with a threadless lid structure as described in any of the above claims, wherein the threadless lid is detachably connected to the cup body 4; the diameter of the cup opening of the cup body 4 is smaller than the diameter inside the cup body 4; when the cup body 4 needs to be sealed, the telescopic component squeezes and deforms the sealing silicone sleeve 3, so that the diameter of the sealing silicone sleeve 3 inside the cup body 4 is larger than the diameter of the cup opening, so that the sealing silicone sleeve 3 fits tightly against the inner wall of the cup body 4 to achieve an interference fit; when the cup body 4 needs to be opened, the press switch 2 is pressed inward, and the telescopic component is driven downward through the transmission mechanism to release the sealing silicone sleeve 3, so that the diameter of the sealing silicone sleeve 3 inside the cup body 4 is smaller than the diameter of the cup opening, thereby opening the water cup.

[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
