Abstract
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:
[0005] The lid has a drinking spout, and there are connecting grooves with the opening facing upward on both sides of the drinking spout.
[0006] The nozzle has connecting shafts protruding from both sides. The connecting shafts are supported in the connecting groove and can rotate within the connecting groove to allow the nozzle to connect to or block the drinking opening.
[0007] A switch is slidably connected to the cover and can switch between covering the slot and avoiding the slot.
[0008] The cup lid provided in this application includes a lid body, a spout, and a switch. The lid body has a drinking spout, and there are connecting grooves with the opening facing upward on both sides of the drinking spout. Connecting shafts protrude from both sides of the spout, and the connecting shafts are supported in the connecting grooves and can rotate within the connecting grooves to allow the spout to connect to or block the drinking spout. The switch is slidably connected to the lid body and can switch between covering the groove and avoiding the groove. That is, the switch slides along the plane of the groove. The user only needs to operate the switch to slide to prevent the connecting shaft from passing through the groove or allow the connecting shaft to pass through the groove. This can ensure the reliability of the spout connection, prevent the spout from accidentally loosening or falling off during use, and simplify the installation and removal of the spout, thereby facilitating the removal and cleaning of the spout and improving the cleanliness and hygiene of the cup.
[0009] Optionally, the switch includes two arms, which are disposed opposite to each other on both sides of the nozzle. The arms extend along the sliding direction of the switch. When the switch slides along the lid, the arms switch between covering the slot and avoiding the slot. The two arms form a space for receiving and flipping the nozzle, allowing the switch and the sliding element to move independently without interference within the narrow space of the lid. This makes the overall structure of the lid more compact and simplifies its use.
[0010] Optionally, a sliding groove is provided above the connecting groove, the sliding groove extending along the sliding direction of the switch, the groove opening being located at the bottom of the sliding groove, and the arm being accommodated within the sliding groove, the arm sliding within the length range of the sliding groove. The arm being accommodated within the sliding groove allows at least a portion of the arm to sink into the groove along the thickness direction of the lid, reducing the height of the arm and thus decreasing the overall thickness of the lid. The arm slides within the length range of the sliding groove, and within the sliding stroke of the switch, the arm remains within the length range of the sliding groove, ensuring that the bottom of the sliding groove provides complete and reliable support for the arm, thereby preventing the end of the arm from being suspended and flipping up and down, leading to deformation, breakage, or falling off.
[0011] Optionally, the slide groove includes a first groove segment and a second groove segment, which are arranged along the sliding direction of the switch component. The first groove segment penetrates the upper surface of the cover, and the groove opening is located at the bottom of the first groove segment. The second groove segment has a stop portion on the upper surface of the cover, and within the sliding stroke of the switch component, a portion of the arm slidably engages with the second groove segment. On the one hand, an unobstructed operating space is formed above the groove opening, ensuring that the nozzle can be installed and removed vertically. On the other hand, the slidable engagement of a portion of the arm with the second groove segment limits the switch component along the thickness direction of the cover, preventing the switch component from detaching from the cover along the thickness direction. Furthermore, since the arm is the main force-bearing part of the switch component, directly limiting the arm can provide a stable and reliable constraint on the connecting shaft, preventing abnormalities such as water leakage caused by nozzle loosening.
[0012] Optionally, the length of the arm is greater than the length of the first groove segment, and the end face of the first groove segment away from the second groove segment is the tail end face, with a guide surface at the top of the tail end face; the guide surface gradually slopes away from the second groove segment along the bottom-up direction. By providing the guide surface, the longer arm can be forcibly squeezed into the slide groove by the shorter first groove segment, and the arm is difficult to detach from the slide groove from the first groove segment in the opposite direction. Therefore, a reliable connection of the switch element on the lid can be achieved solely through the cooperation between the arm and the slide groove, thereby simplifying the overall structure of the cup lid.
[0013] Optionally, the switch further includes a grip portion, and the two arms are connected to each other as a whole through the grip portion; the edge of the cover is provided with a notch, the notch is recessed into the upper surface of the cover, the two sliding grooves are interconnected through the notch, the grip portion is accommodated in the notch, and slides into or out of the cover along the notch. On the one hand, the grip portion forms an exposed structure on both the upper surface of the cover and the edge of the cover, increasing the effective gripping area of the grip portion and increasing the convenience for the user to operate the switch; on the other hand, the grip portion can slide along the notch to the edge of the cover, which can reduce the space occupied by the switch on the cover and increase the utilization rate of the cover space.
[0014] Optionally, the grip portion has an extension between the two arms, the extension extending downward from the edge of the grip portion; a recessed step is provided within the notch away from the edge of the cover, the extension abutting against the surface of the step and sliding along the surface of the step. The grip portion is thinner on the side facing the edge of the cover, which can reduce the depth of the notch at the edge of the cover and maintain the integrity of the cover's own outline as much as possible; the grip portion is thicker on the side facing the axis of the cover, which can increase the effective gripping area of the grip portion and increase the structural strength of the grip portion itself.
[0015] Optionally, the arm spans over the slot, and a clearance opening is provided on the side of the arm facing the nozzle. When the clearance opening is offset from the slot, the arm covers the slot; when the clearance opening is directly opposite the slot, the arm avoids the slot. The two ends of the arm are supported on both sides of the slot, and the middle of the arm covers and avoids the slot, which increases the stability of the fit between the arm and the slot and prevents damage such as collisions or wear between the end face of the arm and the slot.
[0016] Optionally, the cup lid further includes an elastic element that abuts against the switch element to force the switch element to cover the slot. After the user inserts the nozzle's connecting shaft into the connecting slot, they only need to release the switch element. Under the pushing action of the elastic element, the switch element will automatically cover the slot. The user does not need to manually operate the switch element to cover the slot, which simplifies the nozzle installation process. Furthermore, it ensures that the switch element remains stably and reliably in the state of covering the slot, preventing the position of the switch element from changing during use, which could cause the nozzle to loosen or fall off.
[0017] 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.
[0018] 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

[0054] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation
[0055] 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.
[0056] 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.
[0057] 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.
[0058] like Figure 1 As shown in the figure, this application embodiment provides a water cup, which includes a cup body 01 and a cup lid 02. The cup lid 02 is detachably connected to the mouth of the cup body 01. For example, the cup lid 02 is connected to the opening of the cup body 01 by a suitable means such as a snap or thread. A sealing fit can be formed between the cup lid 02 and the cup body 01. For example, a sealing ring can be provided between the cup lid 02 and the cup body 01.
[0059] like Figures 1-7 As shown, the cup lid 02 provided in this embodiment includes a lid body 1, a spout 2, and a switch 3. The lid body 1 is used to connect the cup body 01, realizing the connection and fixation between the cup lid 02 and the cup body 01. The lid body 1 is provided with a drinking port 11, and a straw 111 can be connected to the bottom of the drinking port 11. The straw 111 extends into the cup body 01. The two sides of the drinking port 11 are respectively provided with connecting grooves 121 facing upwards. The two sides of the spout 2 are respectively provided with connecting shafts 21. The connecting shafts 21 are supported in the connecting grooves 12 and can rotate in the connecting grooves 12. That is, the spout 2 rotates around the connecting shafts 21 to make the spout 2 connect to or block the drinking port 11. When the spout 2 connects to the drinking port 11, the user can drink the liquid in the cup through the spout 2. When the spout 2 blocks the drinking port 11, it can prevent the liquid in the cup from leaking through the drinking port 11. The switch 3 is slidably connected to the cover 1 and can switch between covering the slot 121 and avoiding the slot 121. That is, the switch 3 slides along the plane of the slot 121. The user only needs to operate the switch 3 to slide to prevent the connecting shaft 21 from passing through the slot 121 or allow the connecting shaft 21 to pass through the slot 121. This can ensure the reliability of the nozzle 2 connection, prevent the nozzle 2 from accidentally loosening or falling off during use, and simplify the installation and disassembly of the nozzle 2, thereby facilitating the disassembly and cleaning of the nozzle 2 and improving the cleanliness and hygiene of the water cup.
[0060] Specifically, when the switch element 3 covers the slot 121 (refer to...) Figure 2 and Figure 3 The connecting shaft 21 surrounds the switch 3 and the connecting groove 12. The connecting shaft 21 cannot detach from the connecting groove 12, thus ensuring the reliability of the nozzle 2 connection and preventing the nozzle 2 from accidentally loosening or falling off during use. When the switch 3 avoids the groove 121 (refer to...), Figure 4 and Figure 5The connecting shaft 21 can be inserted into or removed from the connecting groove 121 through the slot 121, enabling the installation or removal of the nozzle 2. This facilitates the disassembly and cleaning of the nozzle 2, improving the cleanliness and hygiene of the water cup. Furthermore, with the slot 121 of the connecting groove 12 facing upwards, the user only needs to pull or push the nozzle 2 vertically during installation and removal, providing ample operating space and easy force application. During installation and removal of the nozzle 2, the switch 3 remains connected to the cover 1, reducing the number of parts required for assembly and disassembly, further improving the efficiency of nozzle 2 installation and removal.
[0061] The lid 1 may have a receiving groove 16 on its top, with the drinking spout 11 located at the bottom of the receiving groove 16 and a connecting groove 12 located on the wall of the receiving groove 16. When the spout 2 is connected to the drinking spout 11, the spout 2 is away from the receiving groove 16 and is in use; when the spout 2 blocks the drinking spout 11, the spout 2 is stored in the receiving groove 16 and is in a stored state. A sliding member 5 may be fitted over the spout 2, sliding along the spout 2 to cover the end away from the drinking spout 11 or to expose the spout 2. The top of the lid 1 may also have a direct drinking spout 15, and the cup lid 02 also includes a flip cover 6, which is pivotally connected to the lid 1 to open or close the direct drinking spout 15. The switch member 3 may be configured as any suitable structure, such as a plate, block, or column, as long as it can cover and avoid the groove 121.
[0062] Furthermore, the cup lid 02 also includes an elastic element 4 (e.g., a spring), which abuts against the switch element 3 to force the switch element 3 to cover the slot 121. After the user inserts the connecting shaft 21 of the nozzle 2 into the connecting slot 12, they only need to release the switch element 3. Under the pushing action of the elastic element 4, the switch element 3 can automatically cover the slot 121. The user does not need to manually operate the switch element 3 to cover the slot 121, which simplifies the installation of the nozzle 2. In addition, it can make the switch element 3 stay stably and reliably in the state of covering the slot 121, preventing the position of the switch element 3 from changing during use, which would cause the nozzle 2 to loosen or fall off.
[0063] Furthermore, the switch 3 includes two arms 31, which are disposed opposite to each other on both sides of the nozzle 2, and extend along the sliding direction of the switch 3. When the switch 3 slides along the lid 1, the arms 31 switch between covering the groove 121 and avoiding the groove 121. The two arms 31 form a receiving space and a flipping space for the nozzle 2, allowing the switch 3 and the sliding member 5 to move independently without interference within the narrow space of the lid 1. This makes the overall structure of the cup lid 02 more compact and makes the operation of the cup lid 02 easier.
[0064] Furthermore, the arm 31 is positioned above the slot 121, and a clearance opening 311 is provided on the side of the arm 31 facing the nozzle 2. When the clearance opening 311 is offset from the slot 121, the arm 31 covers the slot 121; when the clearance opening 311 is directly opposite the slot 121, the arm 31 avoids the slot 121. The two ends of the arm 31 are respectively supported on both sides of the slot 121, and the middle part of the arm 31 covers and avoids the slot 121, which increases the stability of the fit between the arm 31 and the slot 121, and also avoids damage such as collision or wear between the end face of the arm 31 and the slot 121. Understandably, in other embodiments, the arm 31 may be disposed on one side of the slot 121, and when the arm 31 slides toward the slot 121, it covers the slot 121, and when the arm 31 slides away from the slot 121, it avoids the slot 121.
[0065] Furthermore, a sliding groove 13 is provided above the connecting groove 12. The sliding groove 13 extends along the sliding direction of the switch element 3, and the groove opening 121 is located at the bottom of the sliding groove 13. The arm 31 is accommodated within the sliding groove 13, meaning that at least a portion of the arm 31 sinks into the sliding groove 13 along the thickness direction of the cover 1, which can reduce the height of the arm 31 and thus reduce the overall thickness of the cup lid 02. The length of the arm 31 is less than the length of the sliding groove 13, and the arm 31 slides within the length range of the sliding groove 13. That is, within the sliding stroke of the switch element 3, the arm 31 is always located within the length range of the sliding groove 13, so that the bottom of the sliding groove 13 provides complete and reliable support for the arm 31, thereby preventing the end of the arm 31 from being suspended and flipping up and down, resulting in deformation, breakage, or falling of the arm 31 and other damage. It is understood that in other embodiments, a portion of the arm 31 can slide outside the length range of the sliding groove 13, so that the arm 31 forms a cantilever structure.
[0066] Furthermore, when the cup lid 02 includes an elastic element 4, the elastic element 4 can be disposed within the receiving groove 16, with both ends of the elastic element 4 abutting against the receiving groove 16 and the arm 31 respectively, thereby forcing the arm 31 to move towards covering the opening 121. The elastic element 4 directly pushes the arm 31 to slide, which can make the action of the switch 3 more sensitive and efficient.
[0067] Furthermore, the slide 13 includes a first groove segment 131 and a second groove segment 132, which are arranged along the sliding direction of the switch 3. The first groove segment 131 penetrates the upper surface of the cover 1, and the groove opening 121 is located at the bottom of the first groove segment 131, forming an unobstructed operating space above the groove opening 121, ensuring that the suction nozzle 2 can be installed and removed vertically. The second groove segment 132 has a stop portion 133 on the upper surface of the cover 1. Within the sliding stroke of the switch 3, a part of the arm portion 31 slides and engages with the second groove segment 132, thereby limiting the switch 3 along the thickness direction of the cover 1, preventing the switch 3 from detaching from the cover 1 along the thickness direction of the cover 1. Furthermore, since the arm portion 31 is the main force-bearing part of the switch 3, directly limiting the arm portion 31 can provide a stable and reliable constraint on the connecting shaft 21, preventing abnormalities such as water leakage caused by loosening of the suction nozzle 2.
[0068] Furthermore, the length of the arm 31 is greater than the length of the first groove segment 131. The end face of the first groove segment 131 away from the second groove segment 132 is the tail end face 1311, and the top of the tail end face 1311 is provided with a guide surface 1312. Along the bottom-up direction, the guide surface 1312 gradually slopes away from the second groove segment 132. By setting the guide surface 1312, the longer arm 31 can be forcibly squeezed into the slide groove 13 from the shorter first groove segment 131, and the arm 31 is difficult to detach from the slide groove 13 from the first groove segment 131 in the opposite direction. Therefore, the reliable connection of the switch 3 on the cover body 1 can be achieved simply by the cooperation between the arm 31 and the slide groove 13, thereby simplifying the overall structure of the cup lid 02.
[0069] Specifically, when assembling the switch 3 with the cover 1, the arm 31 is placed at an angle in the first groove 131. The head of the arm 31 (i.e., the part of the arm 31 that is close to the second groove 132) is lower and extends into the second groove 132, while the tail of the arm 31 (i.e., the part of the arm 31 that is away from the second groove 132) is higher and supported on the guide surface 1312. At this time, by applying force to the tail of the arm 31, the tail of the arm 31 can slide down along the guide surface 1312 and fall into the first groove 131.
[0070] Furthermore, the switch 3 also includes a grip 32, which is located at one end of the nozzle 2. The tails of the two arms 31 are connected to each other as one unit through the grip 32. When the user applies force to the grip 32, the two arms 31 can slide simultaneously without having to operate each arm 31 separately, making the disassembly and assembly of the nozzle 2 easier.
[0071] Furthermore, the edge of the cover 1 is provided with a notch 14, which is recessed into the upper surface of the cover 1. The two sliding grooves 13 are interconnected through the notch 14. The grip part 32 is accommodated in the notch 14 and slides into or out of the cover 1 along the notch 14. On the one hand, the grip part 32 forms an exposed structure on both the upper surface and the edge of the cover 1, increasing the effective gripping area of the grip part 32 and increasing the convenience for the user to operate the switch 3. On the other hand, the grip part 32 can slide along the notch 14 to the edge of the cover 1, which can reduce the space occupied by the switch 3 on the cover 1 and increase the space utilization of the cover 1.
[0072] Furthermore, the grip portion 32 has an extension portion 321 between the two arm portions 31, and the extension portion 321 extends downward from the edge of the grip portion 32. A recessed step 141 is provided within the notch 14 away from the edge of the cover 1, and the extension portion 321 abuts against the surface of the step 141 and slides along the surface of the step 141. The grip portion 32 is thinner on the side facing the edge of the cover 1, which can reduce the depth of the notch 14 at the edge of the cover 1 and maintain the integrity of the cover 1's own outline as much as possible; the grip portion 32 is thicker on the side facing the axis of the cover 1, which can both increase the effective gripping area of the grip portion 32 and increase the structural strength of the grip portion 32 itself.
[0073] 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.
