Description

Technical Field

[0001] This application relates to the field of everyday consumer goods technology, and in particular to a cup lid and a water cup. Background Technology

[0002] A water cup typically consists of a body and a lid, with the lid attached to the mouth of the body to close it. A spout may be attached to the lid, allowing the user to drink from the liquid inside the cup. Usually, the spout is attached to the lid in a non-removable or difficult-to-remove manner, making it difficult to remove and clean, thus affecting the cleanliness and hygiene of the water cup. Utility Model Content

[0003] This application provides a cup lid and a water cup to facilitate the disassembly and cleaning of the spout, thereby improving the cleanliness and hygiene of the water cup.

[0004] The first aspect of this application provides a cup lid, which includes: The lid has a receiving groove on its upper surface, a drinking port at the bottom of the receiving groove, and connecting grooves on two opposite side walls of the receiving groove. At least one of the connecting grooves has an opening on its upward-facing side. A suction nozzle is disposed in the receiving groove. Connecting shafts are respectively provided on opposite sides of the suction nozzle. The connecting shafts are supported in the connecting groove and can rotate in the connecting groove to allow the suction nozzle to connect to or block the drinking port. A switch element is disposed above the slot, the switch element is slidably connected to the cover, and can slide along the axial direction of the connecting shaft to close or open the slot.

[0005] The cup lid provided in this application includes a lid body, a spout, and two switch components. The upper surface of the lid body has a receiving groove, the bottom of which has a drinking spout. Two opposite side walls of the receiving groove each have a connecting groove, and at least one of the connecting grooves has an opening on its upward-facing side. The spout is disposed within the receiving groove, and connecting shafts are located on opposite sides of the spout. The connecting shafts are supported within the connecting grooves and can rotate within them to allow the spout to connect to or block the drinking spout. The switch components are located above the openings and are slidably connected to the lid body. They can slide along the axial direction of the connecting shafts to close or open the openings. Therefore, the user only needs to operate the switch components to slide, preventing the connecting shafts from passing through the openings or allowing at least one side of the connecting shaft to pass through the opening. This ensures the reliability of the spout connection, preventing accidental loosening or detachment during use, and simplifies the installation and removal of the spout, facilitating cleaning and improving the hygiene of the cup. Furthermore, since the movement direction of the switch is perpendicular to the arrangement direction of the nozzle, the limited space on the lid surface can be utilized more effectively, making the overall structure of the cup lid more compact and reasonable.

[0006] Optionally, each of the connecting slots has an opening on its upward-facing side, and the cup lid includes two switching components, each corresponding to one of the connecting slots. This allows the connecting shafts on both sides of the nozzle to pass through the openings simultaneously, enabling the nozzle to be installed and removed simply through vertical translational movement, further simplifying the installation and removal of the nozzle.

[0007] Optionally, a sliding groove is provided above the connecting groove. The sliding groove is recessed into the upper surface of the cover body, extends axially along the connecting shaft and communicates with the receiving groove, and the groove opening is located at the bottom of the sliding groove. The switch element is engaged in the sliding groove and slides along the sliding groove. That is, the switch element and the sliding groove are locked together along the extension direction of the cross section and form a guide along the sliding direction, thereby ensuring that the switch element retains only the axial degree of freedom along the connecting shaft, increasing the stability of the switch element's movement and the reliability of the connection.

[0008] Optionally, the upper surface of the cover is provided with a boss, and both the receiving groove and the sliding groove are provided on the boss. The edges of the receiving groove and the boss are spaced apart, and the end of the sliding groove away from the receiving groove passes through the edge of the boss. On the one hand, by providing a boss to locally thicken the cover, a height space for storing the suction nozzle can be provided, which can avoid the overall weight of the cover being too large. On the other hand, the end of the sliding groove away from the receiving groove forms a mounting port for the switch, which provides a large installation and operation space. Furthermore, the direction of movement of the switch during disassembly and assembly is consistent with the direction of sliding of the switch during operation. Both are perpendicular to the direction of the force exerted by the connecting shaft on the switch, which can effectively prevent the switch from falling off under the squeezing action of the connecting shaft during use.

[0009] Optionally, the slide groove includes a rectangular groove and two opposing slots. The rectangular groove is recessed into the upper surface of the lid, and the slots are recessed into the groove wall of the rectangular groove. The groove opening is located at the bottom of the rectangular groove. The switch component includes a rectangular block and two opposing protrusions. The rectangular block slides with the rectangular groove, and the protrusions slide with the slots. On the one hand, this creates an open structure above the groove opening that is unobstructed and maintains a constant width, allowing the connecting shaft to pass through the slide groove more easily and be aligned with the groove opening for installation. On the other hand, the switch component and the slide groove form a rigid fit, which can significantly improve the load-bearing capacity of the switch component, effectively prevent the switch component from falling off under the pressure of the connecting shaft, and avoid the use of easily damaged elastic elements, thereby extending the service life of the lid.

[0010] Optionally, the end of the slot away from the receiving groove extends through the edge of the boss, and the end of the slot near the receiving groove is provided with a stop surface, with the slot opening located on the side of the stop surface near the receiving groove. On the one hand, by setting the stop surface to stop and limit the boss, the maximum distance of the switch sliding inward is limited, preventing the switch from interfering with or hindering the flipping movement of the nozzle; on the other hand, the slot and the connecting groove are arranged at intervals along the axial direction of the connecting shaft, which can both avoid the cover from forming an excessively weak local structure, ensuring the overall structural strength of the cover, and reduce the overall width of the slide groove, increasing the support rigidity of the slide groove.

[0011] Optionally, the slot is provided with a first suction member, the side of the first suction member facing away from the receiving groove forming the stop surface, and the slot protrudes with a second suction member. The first and second suction members can attract and abut against each other. On the one hand, under the action of the attraction force, the switch can automatically close the slot and remain stably and reliably in the closed slot state, which can simplify the installation of the switch, improve operating efficiency and flexibility, and prevent the slot from accidentally opening during use, causing the nozzle to fall off. On the other hand, the mutual abutment and limiting of the first and second suction members can ensure that the first and second suction members fit tightly, thereby providing a uniform and reliable attraction force.

[0012] Optionally, the boss is located in the center of the cover, and arc-shaped ribs are provided on opposite sides of the boss, with the two ends of the arc-shaped ribs located on opposite sides of the slide groove. This allows the arc-shaped ribs to form a retaining structure outside the mounting opening of the slide groove. When the user slides the switch outwards, completely disengaging it from the slide groove, the switch is contained between the arc-shaped ribs and the boss, preventing it from falling or being lost.

[0013] Optionally, when the switch closes the slot, the end of the switch aligns with the edge of the boss, thereby maintaining a simple and regular overall shape of the cup lid during normal use and improving the appearance of the cup lid.

[0014] Optionally, the lower surface of the switch is provided with a mating groove, and the cross-sections of the connecting groove and the mating groove are semi-circular. When the switch closes the groove, the mating groove and the connecting groove together form a circular hole structure, thereby forming a uniform and continuous arc contact surface around the connecting shaft, making the force distribution more uniform and reducing abnormalities such as stress concentration or local wear.

[0015] A second aspect of this application provides a water cup, which includes a cup body and any of the cup lids provided in this application, wherein the cup lid is detachably connected to the cup body.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0021] In the description of this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0022] like Figures 1-5 As shown, this application embodiment provides a cup lid that can be connected to a cup body and close the opening of the cup body, thereby forming a water cup capable of holding liquid together with the cup body. The cup lid may include a lid body 1 and a spout 2. The lid body 1 is used to connect to the cup body, realizing the connection and fixation between the cup lid and the cup body. The upper surface of the lid body 1 is provided with a receiving groove 11, and the bottom of the receiving groove 11 is provided with a drinking port 12. A straw (not shown in the figure) can be connected below the drinking port 12, and the straw extends into the cup body. The two opposite side walls of the receiving groove 11 are respectively provided with connecting grooves 13. The nozzle 2 is disposed in the receiving groove 11. Connecting shafts 21 are respectively provided on opposite sides of the nozzle 2. The connecting shafts 21 are supported in the connecting groove 13 and can rotate in the connecting groove 13. That is, the nozzle 2 rotates around the connecting shaft 21 to connect or block the drinking opening 12. When the nozzle 2 connects to the drinking opening 12, the nozzle 2 is away from the receiving groove 11 and is in use, and the user can drink the liquid in the cup through the nozzle 2. When the nozzle 2 blocks the drinking opening 12, the nozzle 2 is stored in the receiving groove 11 and is in a stored state, which can prevent the liquid in the cup from leaking through the drinking opening 12.

[0023] Furthermore, at least one of the connecting grooves 13 has an opening on its upward-facing side, forming an unobstructed open structure above the connecting groove 13, allowing the connecting shaft 21 to pass through the opening from top to bottom and be inserted into the connecting groove 13. The cup lid also includes a switch 3, which is disposed above the opening. The switch 3 is slidably connected to the lid body 1 and can slide along the axial direction of the connecting shaft 21 to close or open the opening.

[0024] Therefore, the user only needs to operate the switch 3 to slide, which can prevent the connecting shaft 21 from passing through the slot or allow the connecting shaft 21 on at least one side to pass through the slot. This ensures the reliability of the spout 2 connection, preventing accidental loosening or detachment of the spout 2 during use, and simplifies the installation and removal of the spout 2, thus facilitating the removal and cleaning of the spout 2 and improving the cleanliness and hygiene of the water cup. In addition, since the movement direction of the switch 3 is perpendicular to the arrangement direction of the spout 2, the limited space on the surface of the lid 1 can be utilized more effectively, making the overall structure of the cup lid more compact and reasonable.

[0025] Specifically, when the switch 3 slides towards the receiving groove 11, the switch 3 can close the groove. At this time, the connecting shaft 21 surrounds the switch 3 and the connecting groove 13, and the connecting shaft 21 cannot disengage from the connecting groove 13. This ensures the reliability of the nozzle 2 connection and prevents the nozzle 2 from accidentally loosening or falling off during use (see reference). Figure 1 When the switch 3 slides away from the receiving groove 11, the switch 3 can open the groove. At this time, the connecting shaft 21 can be inserted into or removed from the connecting groove 13 through the groove, realizing the installation or removal of the nozzle 2. This facilitates the removal and cleaning of the nozzle 2 and improves the cleanliness and hygiene of the water cup (see reference). Figure 2 ).

[0026] The switch 3 can be attached to any suitable position, such as the top or side of the lid 1, as long as it allows the switch 3 to close and open the slot. The surface of the switch 3 can be kept smooth and flat to simplify the overall structure and improve the appearance of the lid. The user can use a tool to push the switch 3 from inside the receiving groove 11 to slide the switch 3 outward to open the slot, preventing accidental opening of the slot due to user misoperation. The top of the switch 3 can be provided with a rough surface, ribs, or a handle to facilitate direct operation of the switch 3 with the user's fingers, improving ease of use.

[0027] In one embodiment, one of the connecting grooves 13 has an opening above it, and the other connecting groove 13 is a circumferentially closed annular groove. When the switch 3 opens the opening of the connecting groove 13, the suction nozzle 2 can rotate up and down with the connecting shaft 21 in the annular groove as a fulcrum, so that the connecting shaft 21 at the other end passes through the opening, thereby realizing the installation and removal of the suction nozzle 2.

[0028] In another embodiment, each connecting groove 13 has an opening on its upward-facing side, and the cup lid includes two switching components 3, which are arranged in a one-to-one correspondence with the connecting grooves 13. This allows the connecting shafts 21 on both sides of the nozzle 2 to pass through the openings simultaneously, and the nozzle 2 can be installed and removed simply by vertical translational movement, further simplifying the installation and removal of the nozzle 2.

[0029] Furthermore, a sliding groove 14 is provided above the connecting groove 13. The sliding groove 14 is recessed into the upper surface of the cover 1. The sliding groove 14 extends axially along the connecting shaft 21 and connects to the receiving groove 11. The groove opening is located at the bottom of the sliding groove 14. The switch 3 is inserted into the sliding groove 14 and slides along the sliding groove 14. That is, the switch 3 and the sliding groove 14 are locked together along the extension direction of the cross section and form a guide along the sliding direction. This ensures that the switch 3 retains only the axial degree of freedom along the connecting shaft 21, increasing the stability of the movement of the switch 3 and the reliability of the connection.

[0030] Specifically, the slide 14 can be configured as a stepped structure with a larger bottom and a smaller top, or a tapered structure. Correspondingly, the switch 3 can be configured as a stepped structure with a larger bottom and a smaller top, or a necked structure, etc. Alternatively, a locking structure such as a pin or elastic buckle can be provided between the slide 14 and the switch 3 to cooperate with each other, as long as the switch 3 and the slide 14 can be locked together along the cross-sectional direction and guided along the sliding direction.

[0031] Furthermore, the upper surface of the cover 1 is provided with a boss 15, and the receiving groove 11 and the sliding groove 14 are both provided on the boss 15. By providing the boss 15 to locally thicken the cover 1, the height space for storing the nozzle 2 can be provided, which can avoid the overall weight of the cover 1 being too large.

[0032] Furthermore, the edges of the receiving groove 11 and the boss 15 are spaced apart, and the end of the slide groove 14 away from the receiving groove 11 passes through the edge of the boss 15. This makes the end of the slide groove 14 away from the receiving groove 11 form the mounting opening for the switch element 3, providing a larger installation and operation space. Moreover, the direction of movement of the switch element 3 during installation and removal is consistent with the sliding direction of the switch element 3 during operation; both are perpendicular to the direction of the force exerted by the connecting shaft 21 on the switch element 3. This effectively prevents the switch element 3 from falling off under the squeezing action of the connecting shaft 21 during use. Understandably, in other embodiments, the switch element 3 can be inserted into the slide groove 14 from the end where the receiving groove 11 is located, or the switch element 3 can be forcibly inserted into the slide groove 14 from top to bottom.

[0033] Furthermore, when the switch 3 closes the slot, the end of the switch 3 is aligned with the edge of the boss 15. In other words, the edge contours of the switch 3 and the boss 15 complement each other, so that the cup lid maintains a simple and regular overall shape during normal use and improves the appearance of the cup lid.

[0034] Furthermore, the boss 15 is located in the center of the cover 1 and extends radially along the cover 1. Arc-shaped ribs 16 are respectively provided on opposite sides of the boss 15, with the two ends of the arc-shaped ribs 16 located on opposite sides of the slide groove 14. This allows the arc-shaped ribs 16 to form a retaining structure outside the mounting opening of the slide groove 14. When the user operates the switch 3 to slide it outwards, completely disengaging the switch 3 from the slide groove 14, the switch 3 can be contained between the arc-shaped ribs 16 and the boss 15, preventing the switch 3 from falling and being lost.

[0035] like Figure 4 and Figure 5 As shown, the slide groove 14 further includes a rectangular groove 141 and two opposing slots 142. The rectangular groove 141 is recessed into the upper surface of the cover 1, and the slots 142 are recessed into the groove wall of the rectangular groove 141. The groove opening is located at the bottom of the rectangular groove 141, thus forming an open structure with no obstruction and a constant width above the groove opening, making it easier for the connecting shaft 21 to pass through the slide groove 14 and be aligned with the groove opening for installation. The switch component 3 includes a rectangular block 31 and two opposing protrusions 32. The rectangular block 31 is slidably engaged with the rectangular groove 141, and the protrusions 32 are slidably engaged with the slots 142, thus forming a rigid engagement between the switch component 3 and the slide groove 14. This not only significantly improves the load-bearing capacity of the switch component 3 and effectively prevents the switch component 3 from falling off under the squeezing action of the connecting shaft 21, but also avoids the use of easily damaged elastic elements, thereby extending the service life of the cup lid.

[0036] Furthermore, the end of the slot 142 away from the receiving groove 11 extends through the edge of the boss 15, and the end of the slot 142 near the receiving groove 11 is provided with a stop surface 143, with the slot opening located on the side of the stop surface 143 near the receiving groove 11. On the one hand, by setting the stop surface 143 to stop and limit the boss 15, the maximum distance of the switch 3 sliding inward is limited, preventing the switch 3 from interfering with or hindering the flipping movement of the nozzle 2; on the other hand, the slot 142 and the connecting groove 13 are arranged at intervals along the axial direction of the connecting shaft 21, which can both prevent the cover 1 from forming an overly weak local structure, ensuring the overall structural strength of the cover 1, and reduce the overall width of the slide groove 14, increasing the support rigidity of the slide groove 14.

[0037] Furthermore, a first suction member 144 is provided in the slot 142, and the side of the first suction member 144 facing away from the receiving groove 11 forms a stop surface 143. A second suction member 33 is provided in the protrusion 32. The first suction member 144 and the second suction member 33 attract each other (e.g., magnetic attraction or electrostatic attraction) and abut. That is, when the switch member 3 is pushed into the slide groove 14 from the mounting port, under the action of the attraction force, the switch member 3 can automatically slide into the slide groove 14 until the first suction member 144 and the second suction member 33 abut each other. On the one hand, under the action of the attraction force, the switch member 3 can automatically close the slot and remain stably and reliably in the closed slot state, which can simplify the installation of the switch member 3, improve the operating efficiency and flexibility, and prevent the slot from accidentally opening during use, causing the nozzle 2 to fall off. On the other hand, the mutual abutment and limiting of the first suction member 144 and the second suction member 33 can ensure that the first suction member 144 and the second suction member 33 fit tightly, thereby providing a uniform and reliable attraction force.

[0038] Specifically, at least one of the first adsorption member 144 and the second adsorption member 33 is a magnet, and the other can be a magnet or a material that can be magnetically attracted, such as iron. The first adsorption member 144 can be fixed to the stop surface 143 by any suitable method such as injection molding, snap-fit, or screws. Similarly, the second adsorption member 33 can be fixed to the switch member 3 by any suitable method such as injection molding, snap-fit, or screws.

[0039] Furthermore, the lower surface of the switch element 3 is provided with a mating groove 34. The cross-sections of the connecting groove 13 and the mating groove 34 are semi-circular. When the switch element 3 closes the groove, the mating groove 34 and the connecting groove 13 together form a circular hole structure. This allows a uniform and continuous arc contact surface to be formed around the connecting shaft 21, making the force distribution more uniform and reducing stress concentration or local wear and other abnormalities. Understandably, in other embodiments, the switch element 3 and the connecting groove 13 can form a non-circular hole structure such as a square hole structure or an arched structure.

[0040] This application provides a water cup, which includes a cup body and a cup lid. The cup lid is detachably connected to the mouth of the cup body, for example, the cup lid is connected to the opening of the cup body by a suitable means such as a snap or thread; a sealing fit can be formed between the cup lid and the cup body, for example, a sealing ring can be provided between the cup lid and the cup body.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
