Description

Technical Field

[0001] The invention relates to the technical field of water cups, and in particular to a non-threaded cup cover and a water cup thereof. Background Art

[0002] In today's daily life, cups are widely used beverage containers, and the cup lid is an important part of the cup. Its structure and performance are directly related to the user's experience and health. At present, most cups on the market are equipped with threaded cup lids. However, this traditional threaded cup lid has gradually exposed many problems that are difficult to ignore during long-term use.

[0003] From a health and hygiene perspective, the spiral structure of the threaded cup lid forms complex gaps and grooves, which are very likely to become a breeding ground for dirt and bacteria. In daily environments, cups are inevitably exposed to various impurities, such as dust floating in the air, food particles, etc. These tiny substances are easy to accumulate and remain in the tiny gaps of the threads. When the cup is used to hold various beverages, the liquid remaining in the threads is difficult to clean thoroughly. Under suitable temperature and humidity conditions, it provides an ideal environment for the growth of bacteria, such as harmful bacteria such as Escherichia coli and Staphylococcus aureus. When the user drinks the beverage in the cup again without knowing it, these bacteria may enter the human body, posing a potential threat to the human digestive system and immune system, causing gastrointestinal discomfort symptoms such as abdominal pain, diarrhea, vomiting, etc., seriously affecting physical health.

[0004] In terms of convenience in actual use, the threaded cup lid also brings inconvenience to many people. For children, they are in the stage of physical development, their hand muscle strength is relatively weak, and the coordination and flexibility of fine hand movements are not yet fully mature. When opening or closing the threaded cup lid, it often takes a lot of effort to rotate the cup lid, which is a difficult operation for them. It may even cause difficulty in drinking water due to the inability to open the cup lid smoothly, especially when children are thirsty and urgently need to drink water. This inconvenience will be more prominent, bringing unnecessary troubles to children's normal life and healthy growth. Similarly, as the elderly age, their physical functions gradually decline, their hand muscle strength decreases significantly, and the flexibility of their hand joints is much worse than before, making it more and more difficult to operate the threaded cup lid. This not only reduces the convenience of their use of cups, but may also affect their ability to live independently to a certain extent, bringing many inconveniences and troubles to their daily lives. In addition, for people with disabled or injured hands, due to their limited hand functions, rotating the threaded cup lid has almost become an impossible task, which makes them face great obstacles when using cups, severely restricting their normal use of cups, and thus having a negative impact on their daily lives.

[0005] From the perspective of the service life of the cup cover and the stability of the sealing performance, the threaded connection method has inherent defects. In the process of frequent opening and closing, mutual friction between the threads is inevitable. This continuous friction will gradually wear the thread profile structure, causing the dimensional accuracy and surface roughness of the thread to change. With the increase in the number of uses, the degree of thread wear will gradually increase, resulting in a decrease in the tightness of the fit between the cup cover and the cup, and the sealing performance will also be seriously affected, resulting in frequent water leakage. This will not only cause waste of drinks, but may also cause liquid to leak into the surrounding environment, wet the user's clothes, desktop or other items, and bring many inconveniences and troubles to the user. Moreover, once the thread wear reaches a certain extent, it is often impossible to restore its original performance through simple repair methods. Usually, the entire cup cover needs to be replaced, which undoubtedly increases the economic cost of the user, and also causes waste of resources and environmental pressure.

[0006] In summary, the traditional threaded cup lid has a series of problems in terms of hygiene, ease of use, sealing performance and service life, and an innovative cup lid structure is urgently needed to solve them. Summary of the invention

[0034] See also Figure 1-11 As shown, a non-threaded cup cover comprises a cup cover 1, a push switch 2 arranged on the cup cover 1, a telescopic mechanism and a sealing silicone sleeve 3, wherein the push 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 thereof is connected to the sealing silicone sleeve 3, and the sealing silicone sleeve 3 is arranged at the bottom of the cup cover 1 for sealing or opening the cup mouth of the cup body 4; Fig.11As shown, 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 in the cup body 4 is larger than the diameter of the cup mouth, so that the silicone sleeve fits tightly against the inner wall of the cup body 4 to achieve interference fit; Fig.11 As shown, when the cup body 4 needs to be opened, the push switch 2 is pressed inward, and the transmission mechanism drives the telescopic assembly to move downward to release the sealed silicone sleeve 3, so that the diameter of the sealed silicone sleeve 3 in the cup body 4 is smaller than the diameter of the cup mouth, so as to realize the opening of the water outlet of the cup body 4. Compared with the prior art, the beneficial effect of the present invention is to abandon the traditional thread form and realize the connection between the cup cover 1 and the cup body 4 by adopting the combination of the push switch 2, the transmission mechanism, the telescopic mechanism and the sealed silicone sleeve 3, without thread gaps, reducing the bacterial attachment points, and the sealed silicone sleeve 3 fits the cup body 4 tightly and is easy to clean, effectively avoiding the accumulation of dirt and the breeding of bacteria; at the same time, the pressing operation is labor-saving. Compared with the traditional thread rotation, children, the elderly and people with inconvenient hands can press the switch 2 with less force, and the telescopic assembly drives the sealed silicone sleeve 3 to move through the transmission, so that the cup cover 1 can be easily opened and closed. In terms of sealing performance and lifespan, the telescopic mechanism replaces thread friction with the squeezing and releasing mechanism of the sealing silicone sleeve 3, ensuring a stable interference fit of the sealing silicone sleeve 3 each time it is sealed, maintaining good sealing, avoiding water leakage, reducing beverage waste and soaking of items, while eliminating thread wear and extending the use time of the cup cover 1. Specific embodiment 1:

[0036] like Figure 1 to Figure 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 cover 1 through the valve seat 5. The valve seat 5 is provided with a valve stem 6 and a first compression spring 7. A mounting hole is provided in the middle of the valve seat 5. The upper end of the valve stem 6 is inserted into the mounting hole and is movably connected to the bottom of the rotating member 23. A spring limiter 8 is provided at the upper end of the valve stem 6. The first compression spring 7 is sleeved outside the valve stem 6 and one end abuts against the valve seat 5, and the other end abuts against the spring limiter 8; an extrusion plate 9 is provided at the lower end of the valve stem 6. The sealing silicone sleeve 3 is in the shape of a tube with openings at both ends. One end of the sealing silicone sleeve 3 is connected and fixed to the outer side wall of the valve seat 5, and the other end is connected and fixed to the extrusion plate 9; under the elastic force of the first compression spring 7, the valve stem 6 can drive the extrusion plate 9 to extrude and deform the sealing silicone sleeve 3.

[0037] When the cup body 4 needs to be sealed, the cup cover 1 is placed steadily on the cup body 4. The first compression spring 7 in the telescopic assembly, under the action of its own elastic force, 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 in the cup body 4 is larger than the diameter of the cup mouth, 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, and the sliding inclined surface 20 of the push switch 2 pushes the sliding inclined block 21 of the sliding member 18 to slide along the sliding inclined surface 20, and drives the sliding member 18 to move downward along the sliding channel, thereby driving the telescopic mechanism movably connected to the sliding member 18 to move downward synchronously. In this process, the telescopic mechanism releases the squeezing of the sealing silicone sleeve 3, so that the diameter of the sealing silicone sleeve 3 in the cup body 4 is smaller than the diameter of the cup mouth, thereby opening the water outlet of the cup body 4, making it convenient for the user to take the beverage in the cup. Specific embodiment 2:

[0040] like Figure 1 to Figure 2 As shown, the valve stem 6 is also provided with an exhaust component, 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, and the exhaust rod 10 is inserted into the exhaust channel 13. One end of the exhaust rod 10 is movably connected to the transmission component, and the other end thereof is fixedly connected to the exhaust plug 11. A first limiting clamping ring 14 is provided at the lower end of the exhaust rod 10, and an annular baffle 15 is provided inwardly at the end of the exhaust channel 13. One end of the second compression spring 12 is against the annular baffle 15, and the other end thereof is against the first limiting clamping 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 providing an exhaust assembly, when the exhaust channel 13 is closed, the exhaust rod 10 can be driven downward by pressing the switch 2 through the transmission assembly to overcome the elastic force of the second compression spring 12, thereby driving the exhaust rubber plug 11 at the end to open the exhaust channel 13 for exhaust and pressure relief, and steam and other pressures can be discharged from the exhaust channel 13, thereby preventing the user from being scalded by water vapor when opening the cup body 4. Conversely, the exhaust rod 10 can be driven to move upward by the elastic force of the second compression spring 12, thereby driving the exhaust rubber plug 11 at the end to block and close the exhaust channel 13, thereby ensuring the seal inside the cup body 4 and preventing the liquid inside the cup body 4 from leaking from the exhaust channel 13. Specific embodiment 3:

[0043] like Figure 1 to Figure 2As shown, in order to ensure the accuracy and stability of the vertical sliding of the exhaust rod 10 in the exhaust channel 13, a second limiting clamp ring 16 is further provided at the upper end of the exhaust rod 10. Through the synergistic effect of the first limiting clamp ring 14 and the second limiting clamp ring 16, during the movement of the exhaust rod 10, it is effectively limited from the upper and lower ends, effectively constraining the displacement direction of the exhaust rod 10, so that it always remains in a vertical state, and resolutely eliminating the deviation phenomenon, thereby ensuring the smoothness and reliability of the exhaust process, and avoiding problems such as poor exhaust or mechanical failure caused by the deviation of the exhaust rod 10; at the same time, in order to improve the exhaust effect of the exhaust channel 13, the first limiting clamp ring 14 and the second limiting clamp ring 16 are both provided with exhaust notches 17. In the actual exhaust process, steam or other gases can be realized in the exhaust channel 13 without obstacles by means of these exhaust notches 17, which greatly reduces the flow resistance of the gas at the limiting clamp ring position, effectively avoids the accumulation and blockage of steam in the exhaust channel 13, ensures that the exhaust channel 13 is always unobstructed, and significantly enhances the exhaust effect. Specific embodiment 4:

[0045] like Figures 1 to 4 As shown, the transmission assembly includes a sliding member 18 and a sliding mounting seat 19, the sliding mounting seat 19 is arranged in the cup cover 1, the push switch 2 is arranged on one side of the sliding mounting seat 19, and a sliding inclined surface 20 is provided on the side of the push switch 2 opposite to the sliding mounting seat 19, the sliding member 18 is slidably installed in the sliding mounting seat 19, and the sliding member 18 is movably connected with the telescopic mechanism; the sliding member 18 is provided with a sliding inclined block 21 on the side corresponding to the position of the push switch 2, and a sliding channel 22 is vertically provided on the side wall of the sliding mounting seat 19 corresponding to the position of the sliding inclined block 21, and the sliding inclined block 21 extends outward through the sliding channel 22 to cooperate with the sliding inclined surface 20; when the push switch 2 is pressed inward, the sliding The sliding inclined block 21 of the moving member 18 slides along the sliding inclined surface 20 and drives the sliding member 18 to move downward along the sliding channel 22, and drives the sliding member 18 and the rotating member 23 to move downward. When the rotating member 23 moves downward, the valve seat 5 below is pushed to overcome the elastic force of the first compression spring 7, thereby releasing the squeezing of the sealing silicone sleeve 3, so that the diameter of the sealing silicone sleeve 3 in the cup body 4 is smaller than the diameter of the cup mouth, and the water outlet of the cup body 4 is opened, which is convenient for users to take the beverage in the cup; in this process, the exhaust rod 10 below is also pushed to overcome the elastic force of the second compression spring 12, thereby driving the exhaust rubber plug 11, so that the exhaust rubber plug 11 can open the exhaust channel 13 for exhaust. When it is necessary to seal the cup body 4, the opposite is true. Specific embodiment 5:

[0047] like Figures 1 to 4As shown, a self-locking component that can lock the push switch 2 in the open state is also provided between the sliding member 18 and the telescopic mechanism. The self-locking component includes a rotating member 23. A center hole 24 is provided in the middle of the sliding member 18. The upper end of the rotating member 23 is sleeved in the center hole 24 of the sliding member 18. The rotating member 23 can rotate relative to the sliding member 18. The inner side wall of the sliding mounting seat 19 is evenly provided with vertical limiting convex strips 25. Vertical sliding grooves 26 are formed between adjacent limiting convex strips 25. The periphery of the sliding member 18 corresponds to the position of the sliding groove 26 and is provided with a first sliding block 27 that matches the sliding groove 26. The periphery of the rotating member 23 corresponds to the position of 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 surface of the sliding member 18 is provided with a ratchet 29, the upper end surface 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 inclined to both sides, the first guide slope 30 matches the second guide slope 31, the lower end surface of the limiting convex strip 25 is provided with a limiting groove 32 and a limiting block 33, the lower end surface of the limiting groove 32 is provided with a third guide slope 34, and the lower end surface of the limiting block 33 is provided with a fourth guide slope 35.

[0048] If the cup body 4 needs to be kept open for a long time, the self-locking component can be operated. When the push switch 2 is pressed to drive the sliding member 18 to move downward in the sliding mounting seat 19, the sliding member 18 drives the rotating member 23 to move downward along the sliding mounting seat 19, and the second guiding inclined surface 31 of the ratchet teeth 29 on the lower end surface of the sliding member 18 interacts with the first guiding inclined surface 30 on the upper end surface of the second sliding block 28 of the rotating member 23. When the sliding member 18 drives the second sliding block 28 of the rotating member 23 to move downward to disengage from the sliding groove 26, the second sliding block 28 is stuck between the ratchet teeth 29, forcing the rotating member 23 to rotate relative to the sliding member 18. The second sliding block 28 of the rotating member 23 moves along the third guiding inclined surface 34 of the limiting groove 32 to the limiting groove 32 on the lower end surface of the limiting convex strip 25 and is blocked by the limiting block 33 and cannot be separated from the limiting groove 32, that is, the rotating member 23 is locked in the current position, so as to limit the rotating member 23, so that the valve stem 6 that abuts against the bottom of the rotating member 23 cannot be pushed by the first compression spring 7 under its own elastic force to drive the extrusion plate 9 to squeeze the sealing silicone sleeve 3, thereby locking the position of the valve stem 6 and keeping the cup body 4 open. At the same time, the exhaust rod 10 that abuts against the bottom of the rotating member 23 cannot be pushed by the second compression spring 12 under its own elastic force to drive the exhaust rubber plug 11 to close the exhaust channel 13, thereby locking the position of the exhaust rod 10, so that the exhaust channel 13 remains open.

[0049] When the cup body 4 needs to be resealed, the self-locking assembly can be operated. Press the push switch 2. When the push switch 2 is pressed, the sliding member 18 is driven to move downward in the sliding mounting seat 19. The sliding member 18 drives the rotating member 23 to move downward in the opposite direction of the sliding mounting seat 19 again. The second guide slope 31 of the ratchet 29 on the lower end surface of the sliding member 18 interacts with the first guide slope 30 on the upper end surface of the second sliding block 28 of the rotating member 23. At this time, the rotating member 23 is located in the limiting groove 32. When the sliding member 18 drives the second sliding block 28 of the rotating member 23 to move downward to disengage from the limiting groove 32, the second sliding block 28 is stuck between the ratchet 29, forcing the rotating member 23 to move relative to the rotating member 23 again. The sliding member 18 rotates, and the second sliding block 28 of the rotating member 23 is rotated and displaced to the limiting block 33 at the lower end surface of the limiting convex strip 25, and slides into the sliding groove 26 again along the fourth guide inclined surface 35 of the limiting block 33, so that the second sliding block 28 gradually disengages from the limiting groove 32, and moves upward along the sliding groove 26 of the limiting convex strip 25 until it returns to the initial normal position, so that the valve stem 6 against the bottom of the rotating member 23 can be pushed by the first compression spring 7 under its own elastic force to drive the extrusion plate 9 to squeeze the sealing silicone sleeve 3, thereby unlocking the position of the valve stem 6 and maintaining the sealing state of the cup body 4. At the same time, the exhaust rod 10 against the bottom of the rotating member 23 can also be pushed by the second compression spring 12 under its own elastic force to drive the exhaust rubber plug 11 to close the exhaust channel 13, thereby unlocking the position of the exhaust rod 10, so that the exhaust channel 13 remains in a closed state. Specific embodiment 6:

[0051] like Figure 5 to Figure 6As shown, in order to prevent misoperation of the push switch 2, in daily use, the water cup may be placed in a backpack, pocket or other environment that is easily squeezed. At this time, the switch locking component of the cup cover 1 plays a key role. By pushing the locking button 37 to the locking end, the limit rod 38 tightly presses against the limit protrusions 40 of the two push switches 2, so that the push switch 2 cannot be accidentally pressed. For example, during outdoor activities, people may move their bodies frequently. If there is no switch locking component, it is very likely that the cup cover 1 will be accidentally opened due to inadvertent collision or squeezing of the body, causing the drink to spill. This component effectively avoids this situation and ensures the sealing and safety of the water cup during carrying. Therefore, specifically, the cup cover 1 is symmetrically provided with two push switches 2, and the cup cover 1 is movably provided with a switch locking assembly between the two push switches 2, and the switch locking assembly includes a slide groove 36 opened on the top of the cup cover 1 and a locking button 37 slidably arranged 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 in the cup cover 1, and the locking slider includes a limit rod 38 arranged horizontally and a guide rod 39 arranged horizontally in the middle of the limit rod 38, and the position of the push switch 2 corresponding to the limit rod 38 is provided with a limit protrusion 40; Figure 5 As shown, when it is necessary to lock the push switch 2, the locking button 37 is pushed along the direction of the locking end of the slide groove 36 to the locking end, so that the two ends of the limit rod 38 are respectively against the limit protrusions 40 of the two push switches 2, so that the two push switches 2 cannot be pressed and moved inward; when it is necessary to unlock the push switch 2, the locking button 37 is pushed along the direction of the unlocking end of the slide groove 36 to the unlocking end, and the limit rod 38 and the limit protrusions 40 of the two push switches 2 are offset and separated, so that the push switch 2 can move inward.

[0052] like Figure 6 The cup cover 1 is provided with a guide rail 41 at a position corresponding to the guide rod 39. The guide rod 39 slides and moves along the direction of the guide rail 41. When the locking button 37 drives the limit rod 38 to move, the guide rod 39 slides in the guide rail 41, strictly limiting the displacement path and range of the limit rod 38, ensuring that the limit rod 38 can accurately reach the predetermined position and achieve accurate locking or unlocking cooperation with the limit protrusion 40 of the push switch 2. This precise positioning mechanism effectively avoids problems such as locking failure or poor unlocking caused by rotation deviation, and ensures the reliability and stability of the operation of the cup cover 1. Specific embodiment 7:

[0054] like Figures 7 to 9As shown, in complex usage environments, such as outdoor travel, sports scenes or daily carrying, the water cup may be subjected to various external impacts and bumps. Therefore, the cup cover 1 is provided with a sliding locking assembly, which includes a transverse opening 42 opened on the side wall of the cup cover 1 and a convex column button 43 slidably arranged on the transverse opening 42, one end of the transverse opening 42 is a locking end, and the other end is an unlocking end; the cup cover 1 is rotatably provided with a rotating ring 44 around the sliding mounting seat 19, and the rotating ring 44 is connected to the convex column button 43; the rotating ring 44 extends inwardly to the sliding bevel 21 of the sliding member 18 and is provided with a stop block 55; when the sliding member 18 needs to be locked, the convex column button 43 is pushed to move to the locking end along the direction of the locking end of the transverse opening 42, and the convex column button 43 is unlocked. The rotating ring 44 connected thereto is driven to rotate around the sliding mounting seat 19, so that the stop block 55 is displaced to the bottom of the sliding bevel block 21 of the sliding member 18 and abuts against the bottom of the sliding bevel block 21, so that the sliding bevel block 21 of the sliding member 18 cannot be displaced downward along the sliding channel 22; when the sliding member 18 needs to be unlocked, the boss button 43 is pushed along the direction of the unlocking end of the transverse opening 42 to be displaced to the unlocking end, and the rotating ring 44 connected thereto is driven to rotate around the sliding mounting seat 19 through the boss button 43, so that the stop block 55 is displaced to the position of the sliding bevel block 21 of the sliding member 18, so that the sliding bevel block 21 of the sliding member 18 can be displaced downward along the sliding channel 22.

[0055] like Fig. 9 As shown, when the sliding member 18 needs to be locked, the boss button 43 is pushed to the locking end, and the rotating ring 44 connected to the pushing boss drives the stop block 55 to move below the sliding bevel block 21 of the sliding member 18, thereby hindering the sliding bevel block 21 of the sliding member 18, so that the displacement of the sliding bevel block 21 in the vertical direction is completely restricted, thereby ensuring that when the cup cover 1 does not need to be opened, even if it is subjected to unexpected external pressure or vibration, the sliding member 18 will not be displaced when the switch 2 is pressed, effectively preventing the cup cover 1 from being accidentally opened due to misoperation, and greatly improving the stability and safety of the cup cover 1 in the closed state.

[0056] Similarly, when unlocking is required, the boss button 43 only needs to be pushed toward the unlocking end, and the rotating ring 44 rotates synchronously, driving the stop block 55 to move away from under the sliding inclined block 21, so that the stop block and the sliding inclined block 21 are staggered, and the restriction on the sliding inclined block 21 is released. At this time, the sliding member 18 can move freely in the sliding channel 22, and the pressing switch 2 can normally drive the sliding member 18 and the subsequent telescopic mechanism to work, so as to realize the smooth opening of the cup cover 1. The entire unlocking operation is simple and easy, without complicated steps or tools, and can quickly meet the user's needs for taking the drink in the cup, ensuring the smoothness of use.

[0057] Furthermore, the sliding mounting seat 19 is provided with a limiting protrusion 46 at the outer side wall connected to the rotating ring 44, and the inner side wall of the rotating ring 44 is provided with a first positioning groove 47 corresponding to the limiting protrusion 46, and a second positioning groove 48 is provided on one side of the first positioning groove 47. The first positioning groove 47 and the second positioning groove 48 are connected to each other and provided with a transition portion 49. During the operation of the above-mentioned sliding locking assembly, the limiting protrusion 46 on the outer side wall of the sliding mounting seat 19 is closely matched 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 boss button 43 drives the rotating ring 44 to rotate, the limiting protrusion 46 slides in the first positioning groove 47, strictly limiting the rotation path and angle range of the rotating ring 44, ensuring that the stopper block 55 can accurately reach the predetermined position, and realize accurate locking or unlocking cooperation with the sliding inclined block 21 of the sliding member 18. This precise positioning mechanism effectively avoids the problems of locking failure or poor unlocking caused by rotation deviation, and ensures the reliability and stability of the operation of the cup cover 1.

[0058] In summary, both the switch locking assembly and the sliding locking assembly can realize effective control over the opening function of the cup cover 1 , and the two can be used simultaneously to complement each other or selected according to actual conditions.

[0059] The switch locking component focuses on the direct control restriction of the push switch 2. Through the slide groove 3 on the top of the cup cover 1 and the matching locking button 37, locking slider and other components, when in the locked state, its limit rod 38 accurately presses against the limit protrusion 40 of the push switch 2, eliminating the possibility of accidental opening of the cup cover 1 due to mis-touching the push switch 2. In scenarios such as placing the water cup in a backpack, pocket or in a bumpy transportation environment, it plays a vital role, effectively ensuring the sealing of the water cup, avoiding the occurrence of beverage leakage, and greatly improving the safety and convenience of users during use.

[0060] The sliding locking assembly focuses on locking the key link of the transmission path - the sliding member 18. By using the lateral opening 42 on the side wall of the cup cover 1, the boss button 43, the rotatable rotating ring 44 and the stop block 55 thereon, when the boss button 43 is pushed to the locking end, the stop block 55 can accurately move to the bottom of the sliding bevel 21 of the sliding member 18 and tightly abut against it, so that the sliding bevel 21 cannot move downward along the sliding channel 22, thereby cutting off the power transmission link between the push switch 2 and the telescopic mechanism. Similarly, when the water cup is subjected to a large external impact, vibration or in a complex use environment, it can effectively prevent the cup cover 1 from opening due to unexpected factors, providing a reliable secondary guarantee for the closed state of the cup cover 1, and further enhancing the stability of the structure of the threadless cup cover 1.

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

[0062] like Fig.10 and Fig.11 As shown, a water cup is also disclosed, including a cup body 4 with a non-threaded cup cover structure as described in any of the above items, and the non-threaded cup cover is detachably connected to the cup body 4; the diameter of the cup mouth of the cup body 4 is smaller than the diameter inside the cup body 4, and 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 mouth, 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 push switch 2 is pressed inward, and the telescopic component is driven by the transmission mechanism to move downward 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 mouth, so as to open the water cup.
