Description

Technical Field

[0001] This invention relates to the field of water cup technology, and more particularly to a cup lid and water cup with an easy-to-disassemble spout. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] To meet the convenient and efficient daily needs of today's young people, water cups with integrated spouts are increasingly common in the market, with the integrated spout structure becoming the mainstream design. For example, patent application CN202421731889.6 discloses a water cup with a spout structure, where the spout assembly is rotatably mounted on the top of the lid. However, this prior art has a significant drawback: when the spout assembly needs to be disassembled for cleaning, a considerable pulling force must be applied to separate the rotating shaft from the shaft hole, resulting in a poor overall disassembly experience. To address the shortcomings of the prior art, this application provides a lid and water cup with an easily detachable spout, thus solving the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a cup lid and water cup with an easily detachable spout.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cup lid with an easily detachable spout includes a cup lid body, a receiving groove on the top of the cup lid body, and a spout assembly rotatably mounted in the receiving groove. One end of the spout assembly is a sucking end, and the other end is a rotating end. Elastic cantilever arms are provided on both sides of the rotating end, and clearance grooves are provided on the rotating end corresponding to the positions of each elastic cantilever arm. The clearance grooves allow the elastic cantilever arms to elastically deform and move closer to the rotating end. A rotating shaft is fixed to the side of each elastic cantilever arm away from the rotating end, and the rotating shaft rotatably engages with shaft holes on both sides of the receiving groove. The receiving groove is provided with a stop block at the position of the relief groove on both sides of the rotating end, and the top of the stop block extends into the relief groove; the stop block is used to limit the elastic cantilever and restrict the elastic cantilever from deforming towards the side closer to the rotating end; when the suction nozzle assembly is rotated to a preset disassembly angle, the stop block and the relief groove disengage from each other.

[0006] Furthermore, the inner wall of the receiving groove is provided with raised protrusions corresponding to the position of the elastic cantilever; when the suction nozzle assembly is rotated to a preset disassembly angle, the protrusions abut against and squeeze the elastic cantilever, causing the elastic cantilever to deform towards the side closer to the rotating end, thereby driving the rotating shaft to move in the direction of disengaging from the shaft hole.

[0007] Furthermore, the rotating end is provided with a first locking point, and the receiving groove is provided with a matching clearance slot at the position corresponding to the first locking point; during the rotation and opening process of the suction nozzle assembly, the first locking point is driven to move along the inside of the clearance slot. When the suction nozzle assembly rotates to a preset disassembly angle, the first locking point and the clearance slot are pressed against each other and disengaged from the clearance slot.

[0008] Furthermore, the first locking point is located on the side of the rotating end opposite to the suction end; when the nozzle assembly is in the retracted state, the first locking point is located above the rotating shaft; during the rotation of the nozzle assembly to a preset disassembly angle, the first locking point rotates downward and abuts against the clearance slot, and the clearance slot applies an upward pushing force to the rotating shaft by means of the reverse force generated by the abutment, assisting the rotating shaft to separate from the shaft hole; after continuously rotating the nozzle assembly to the preset disassembly angle, the first locking point disengages from the clearance slot.

[0009] Furthermore, one side of the end face of the rotating shaft is formed with a bevel; when the nozzle assembly is rotated to a preset disassembly angle, the bevel of the rotating shaft faces upward.

[0010] Furthermore, it also includes a dust cover, which is used to cover the suction end of the nozzle assembly when the nozzle assembly is in the retracted state.

[0011] Furthermore, the dust cover is rotatably mounted on the nozzle assembly, and the dust cover can only be flipped up and down within a limited range relative to the nozzle assembly; the opening rotation direction of the dust cover is the same as the opening rotation direction of the nozzle assembly; after the dust cover is flipped up and opened, it abuts against the nozzle assembly, and when the dust cover is continuously rotated, it can drive the nozzle assembly to flip up and open synchronously by means of lever transmission.

[0012] Furthermore, the suction nozzle assembly is provided with a second locking point; after the dust cover is flipped open, it abuts and presses against the second locking point, and flips over the second locking point, the second locking point being used to limit and constrain the movement position of the dust cover.

[0013] Furthermore, a third locking point is provided on each side of the dust cover; a limiting slot is provided on each side of the receiving groove corresponding to the position of each of the third locking points, and the limiting slot is used to limit the dust cover when both the mouth assembly and the dust cover are in the closed state.

[0014] A water cup includes a cup body, on which a cup lid with a removable spout is provided as described above.

[0015] The beneficial effects of this invention are reflected in: The elastic cantilever and clearance groove of this invention allow the nozzle assembly to be disassembled more easily by deforming the elastic cantilever during disassembly. By setting a stop that can extend into the clearance groove on the receiving groove, and having the stop locked in the clearance groove in the normal use state, the elastic cantilever is rigidly limited, preventing the shaft from accidentally coming out of the shaft hole during use. Only when the nozzle assembly is rotated to a preset disassembly angle will the stop separate from the clearance groove, releasing the deformation restriction on the elastic cantilever. This combines the locking and anti-dislodgement effect for daily use with the advantages of convenient and labor-saving disassembly. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 4This invention discloses a cup lid with an easy-to-disassemble spout, comprising a cup lid body 1, a receiving groove 11 disposed on the top of the cup lid body 1, and a spout assembly 2 rotatably assembled in the receiving groove 11; one end of the spout assembly 2 is a sucking end 21, and the other end is a rotating end 22; elastic cantilever arms 23 are respectively provided on both sides of the rotating end 22, and a relief groove 221 is provided on the rotating end 22 at the position corresponding to each elastic cantilever arm 23, the relief groove 221 is used to allow the elastic cantilever arm 23 to elastically deform and make way in the direction closer to the rotating end 22; a rotating shaft 24 is fixedly provided on the side of the elastic cantilever arm 23 away from the rotating end 22, and the rotating shaft 24 is rotatably engaged with the shaft holes disposed on both sides of the receiving groove 11; The receiving groove 11 is provided with a stop 13 at the position of the relief groove 221 on both sides of the rotating end 22. The top of the stop 13 extends into the relief groove 221. The stop 13 is used to limit the elastic cantilever 23 and restrict the elastic cantilever 23 from deforming towards the side closer to the rotating end 22. When the suction nozzle assembly 2 is rotated to the preset disassembly angle, the stop 13 disengages from the relief groove 221.

[0020] This invention features a stop 13 on the receiving groove 11 that can extend into the relief groove 221. Under normal use, the stop 13 is engaged within the relief groove 221, providing a rigid limit to the elastic cantilever 23. This prevents the rotating shaft 24 from accidentally dislodging from the shaft hole during use, effectively preventing the nozzle assembly 2 from detaching abnormally during drinking, carrying, shaking, or dropping, thus improving the stability of the structural connection. The stop 13 only separates from the relief groove 221 when the nozzle assembly 2 rotates to a preset disassembly angle, releasing the deformation restriction on the elastic cantilever 23. This design balances the locking and anti-detachment effect for daily use with the convenience and effortlessness of disassembly. The structure is integrally molded without additional snap-fit ​​accessories, resulting in a simple part structure and convenient assembly and processing. The limiting structure is not prone to wear and failure during long-term repeated opening and closing, extending its service life.

[0021] Preferably, an arc-shaped notch is provided on the elastic cantilever 23 at the position corresponding to the stop block 13. The arc-shaped notch exposes the stop block 13 when the suction nozzle assembly 2 is rotated to a preset disassembly angle, so that the stop block 13 releases its restriction on the elastic cantilever 23.

[0022] In one embodiment, the inner wall of the receiving groove 11 is provided with a raised protrusion 12 corresponding to the position of the elastic cantilever 23; when the suction nozzle assembly 2 rotates to a preset disassembly angle, the protrusion 12 abuts against and squeezes the elastic cantilever 23, causing the elastic cantilever 23 to deform toward the side closer to the rotating end 22, thereby driving the rotating shaft 24 to move toward the direction of disengaging from the shaft hole.

[0023] This invention provides a structure by setting protrusions 12 on the inner wall of the receiving groove 11 and setting elastic cantilever 23 with relief grooves 221 and rotating shaft 24 on both sides of the rotating end 22 of the suction assembly 2. When the suction assembly 2 rotates to a preset disassembly angle, the protrusions 12 on the receiving groove 11 can automatically squeeze the elastic cantilever 23 on both sides to deform towards the rotating end 22, and simultaneously drive the rotating shaft 24 to retract inward and separate from the shaft holes on both sides of the receiving groove 11. The disassembly operation can be completed without the user applying a large pulling force to the suction assembly 2, which greatly reduces the disassembly force required for the suction assembly 2. The disassembly and assembly operation is simple and labor-saving, improving the user experience. The overall structure is compact, requiring no additional disassembly auxiliary accessories, with few parts, simple assembly, and low production cost.

[0024] Preferably, the elastic cantilever 23 can be designed in an L-shape, with one end of the L-shape fixedly connected to the rotating end 22, and the other end of the L-shape extending away from the suction end 21. The elastic cantilever 23 can be integrally formed with the rotating end 22.

[0025] In one embodiment, the rotating end 22 is provided with a first locking point 222, and the receiving groove 11 has a corresponding clearance groove 14 at the position corresponding to the first locking point 222. During the rotation and opening process of the suction nozzle assembly 2, the first locking point 222 moves along the interior of the clearance groove 14. When the suction nozzle assembly 2 rotates to a preset disassembly angle, the first locking point 222 and the clearance groove 14 press against each other and disengage from the clearance groove 14. The first locking point 222 and the clearance groove 14 limit each other, and under normal use, the suction nozzle assembly 2 can be restricted from rotating freely to the preset disassembly angle, and can only be rotated to the preset disassembly angle during disassembly operations.

[0026] This invention forms a rotation limiting structure by setting a first locking point 222 at the rotating end 22 of the spout assembly 2 and matching a clearance slot 14 in the receiving groove 11. During daily drinking, the first locking point 222 is always confined inside the clearance slot 14, forming a rotation damping limit. This effectively prevents the spout assembly 2 from being accidentally rotated to a disassembly angle, avoiding the spout assembly 2 from unlocking and falling off on its own when carried, shaken, or accidentally touched, thus greatly improving the structural stability during daily use. Only when the user actively applies a torsional force and deliberately rotates the spout assembly 2 to a preset disassembly angle can the first locking point 222 squeeze the clearance slot 14 and disengage, accurately distinguishing between normal opening and disassembly. The limiting structure is integrally formed with the cup lid and spout, eliminating the need for additional locking parts. The overall structure is simple and compact, with simple molding and assembly processes and low production costs.

[0027] In one embodiment, the first locking point 222 is located on the side of the rotating end 22 away from the suction end 21; when the suction nozzle assembly 2 is in the retracted state, the first locking point 222 is located above the rotating shaft 24; during the rotation of the suction nozzle assembly 2 to the preset disassembly angle, the first locking point 222 rotates downward and abuts against the clearance groove 14, and the clearance groove 14 applies an upward pushing force to the rotating shaft 24 by means of the reverse force generated by the abutment, assisting the rotating shaft 24 to separate from the shaft hole; after the suction nozzle assembly 2 is continuously rotated to the preset disassembly angle, the first locking point 222 disengages from the clearance groove 14.

[0028] In this invention, the first locking point 222 is positioned on the side of the rotating end 22 away from the sucking end 21. In the retracted state, the locking point is positioned above the rotating shaft 24. When the spout is rotated for normal drinking, the locking point will not press against the clearance groove 14, ensuring smooth opening and closing without jamming. Only when the user actively twists the spout towards the disassembly angle, the downward-rotating locking point presses against the clearance groove 14, using the reverse force of the groove to apply an upward pushing force to the rotating shaft 24. This, combined with the structure where the protrusion 12 compresses the elastic cantilever 23, causing the rotating shaft 24 to retract inward, forms a double disassembly aid. The external force required to disassemble the nozzle is greatly reduced, making disassembly easy and convenient. When the nozzle is fully rotated to the disassembly angle, the locking point automatically disengages from the clearance slot 14. The locking point and clearance slot 14 are integrally formed on the original structure, eliminating the need for additional auxiliary pushing parts. The overall structure is simplified and compact, and the mold injection molding and assembly process is simple, effectively reducing production and manufacturing costs. Moreover, the locking point and slot only come into contact and rub against each other during disassembly, resulting in minimal wear during daily use. After long-term repeated disassembly and rotation, the limiting and assist functions are not prone to failure, effectively extending the overall service life of the cup lid.

[0029] In one embodiment, one side of the end face of the rotating shaft 24 is formed with a bevel; when the nozzle assembly 2 is rotated to a preset disassembly angle, the bevel of the rotating shaft 24 is arranged facing upward.

[0030] This application provides a beveled structure on one side of the end face of the rotating shaft 24. After the nozzle assembly 2 is rotated to the disassembly angle, the bevel faces upward. During the process of the rotating shaft 24 disengaging from the shaft hole, the upward-facing bevel can form a smooth guiding fit with the edge of the shaft hole, eliminating the jamming and scraping resistance caused by the hard contact of the corners when the rotating shaft 24 is disengaged, further reducing the external force required to disassemble the nozzle assembly 2, and making the disassembly and assembly operation smoother and less strenuous.

[0031] In one embodiment, a dust cover 3 is also included, which is used to cover the sucking end 21 of the nozzle assembly 2 when the nozzle assembly 2 is in the retracted state.

[0032] This invention adds a dust cover 3 structure. When the mouthpiece assembly 2 is folded and stored, the dust cover 3 can completely cover the sucking end 21, effectively preventing external dust, water stains, food residue, and pollutants in the environment from directly contacting the sucking end 21, avoiding dirt from the sucking end 21 and ensuring the user's drinking water hygiene. At the same time, the dust cover 3 can provide physical protection for the sucking end 21, preventing it from being deformed or damaged by external objects during the process of carrying the water cup, thus extending the service life of the mouthpiece assembly 2. The dust cover 3 can be adapted and assembled with the cup lid body 1, with a simple structure and convenient disassembly and assembly, without increasing the overall volume of the cup lid, making it easy to carry.

[0033] In one embodiment, the dust cover 3 is rotatably mounted on the nozzle assembly 2, and the dust cover 3 can only be flipped up and down relative to the nozzle assembly 2 within a limited range; the opening rotation direction of the dust cover 3 is consistent with the opening rotation direction of the nozzle assembly 2; after the dust cover 3 is flipped up and opened, it abuts against the nozzle assembly 2, and when the dust cover 3 is continuously rotated, it can drive the nozzle assembly 2 to flip up and open synchronously by means of lever transmission.

[0034] This invention rotatably mounts the dust cover 3 onto the nozzle assembly 2 and limits its rotation stroke. The opening direction of the dust cover 3 and the nozzle assembly 2 is consistent. After the dust cover 3 is lifted until it fits against the nozzle, the nozzle assembly 2 can be opened simultaneously by levering the force of the lever structure. There is no need to operate the dust cover 3 and the nozzle separately. The dust cover 3 can be opened and the nozzle can be popped out with a single rotation action, which simplifies the operation of opening the water cup and greatly improves the convenience of use. At the same time, the nozzle assembly 2 can be opened with less effort.

[0035] Preferably, the rotation center of the dust cover 3 is offset from the rotation center of the nozzle assembly 2. The offset arrangement forms an extended lever arm, which reduces the operating force required to open the nozzle assembly 2, making it easier to flip and open the nozzle assembly 2. At the same time, it can also rotate the nozzle assembly 2 to the preset disassembly angle with relatively little effort.

[0036] In one embodiment, the suction nozzle assembly 2 is provided with a second locking point 25; after the dust cover 3 is flipped open, it abuts and presses against the second locking point 25 and flips over the second locking point 25. The second locking point 25 is used to limit and constrain the movement position of the dust cover 3.

[0037] This invention features a second locking point 25 on the nozzle assembly 2. After the dust cover 3 is flipped upwards and passes the second locking point 25, it can be fixed by the locking point, preventing the dust cover 3 from shaking freely after opening and rebounding downwards to block the suction end 21. This eliminates the need to manually hold the dust cover 3 continuously, improving the convenience of drinking operations. At the same time, the dust cover 3 generates a slight damping feel when it flips over the second locking point 25, providing clear feedback to the user and making it easy to intuitively judge whether the dust cover 3 is fully opened. The locking point limiting structure is integrally molded into the nozzle assembly 2, eliminating the need for additional locking parts such as buckles and springs. The structure is simple and compact, the injection molding and assembly processes are simplified, and the production cost is lower.

[0038] In one embodiment, the dust cover 3 is provided with third locking points 31 on both sides; the receiving groove 11 is provided with limiting slots 15 on both sides corresponding to the positions of the third locking points 31. The limiting slots 15 are used to limit the dust cover 3 when both the nozzle assembly and the dust cover 3 are in the closed state.

[0039] This application provides third locking points 31 on both sides of the dust cover 3 and a limiting slot 15 at the corresponding position of the receiving groove 11. When the suction nozzle assembly 2 and the dust cover 3 are fully closed and stored, the third locking points 31 are engaged with the limiting slot 15 to form a locking and limiting structure, which can effectively lock the dust cover 3 and prevent the dust cover 3 from accidentally opening during the shaking or bumping of the water cup. This ensures that the dust cover 3 continues to fit and cover the suction end 21, and stably maintains the dustproof and anti-fouling effect.

[0040] The present invention also discloses a water cup, which includes a cup body (not shown in the figure) and a cup lid with a removable spout as described above.

[0041] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0042] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0043] Additionally, "multiple" refers to two or more.
