Description

Technical Field

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

[0002] Water cups are typically containers used to hold liquids, and water cup lids are structures that seal the cup to prevent spills and improve its insulation. As people's living standards improve, they have new demands for the structure and opening mechanisms of water cup lids, which current market offerings cannot fully meet. Utility Model Content

[0003] To address the aforementioned problems, this application provides a water cup lid and a water cup, featuring an ingenious design, novel structure, and unique opening method. By screwing on the upper lid, this application can control the extension and retraction of the suction tube relative to the upper lid, allowing the suction tube to extend above or retract below the upper lid. The technical solution adopted in this application is as follows:

[0004] A water cup lid includes: a lid base, an upper lid body, a transmission component, and a water suction tube;

[0005] The outer wall of the suction tube has a protrusion; the cup lid base has a through hole for the suction tube to make way; a limiting structure is provided between the cup lid base and the suction tube to prevent the suction tube from rotating relative to the cup lid base; the upper cover is located on the upper end face of the cup lid base and is adapted to rotate relative to the cup lid base around its own axis; the upper cover has an arc-shaped clearance groove for the suction tube to make way; the transmission component is located at the bottom of the upper cover and is coaxially arranged with the upper cover, and is adapted to rotate synchronously with the upper cover; the side wall of the transmission component has a sliding guide groove, the protrusion extends into the sliding guide groove, and the protrusion moves along the sliding guide groove when the upper cover is screwed on;

[0006] In the first state, both the perforation and the suction tube are covered by the upper cover. When the upper cover is gradually screwed down in the first direction from the first state, the upper cover first removes the cover from the perforation and the suction tube. As the upper cover is screwed down further, the suction tube moves outward along the perforation and gradually extends out of the upper cover through the relief groove. When the upper cover is screwed down in the opposite direction from the first direction, the suction tube first moves inward along the perforation. As the upper cover is screwed down further, the cup lid enters the first state.

[0007] The water cup lid of this application features an ingenious design, novel structure, and unique opening mechanism. The main differences between this water cup lid and existing technologies include: this application transforms the rotational movement of the upper lid into the extension and retraction (translational) movement of the drinking tube. By screwing on the upper lid, the upper lid drives the transmission component to rotate. The rotation of the transmission component causes the protrusion on the drinking tube to move along the sliding guide groove. The movement of the protrusion drives the entire drinking tube to move vertically relative to the upper lid. When the water cup lid is in its first state, the drinking tube and the perforation are covered under the upper lid, preventing contamination of the drinking tube and the perforation and ensuring cleanliness and hygiene. When drinking water is needed, the drinking tube can be extended from the upper lid by screwing on the upper lid in the first direction; when drinking water is not needed, the drinking tube can be retracted back under the upper lid by screwing on the upper lid in the opposite direction of the first direction.

[0008] In some embodiments, the sliding guide groove includes a first section and a second section. The first section is located at the same height along the axial direction of the transmission member, and the second section is spirally distributed along the axial direction of the transmission member. The lower ends of the first and second sections are connected. When the protrusion moves along the first section of the sliding guide groove, the suction tube remains stationary relative to the perforation. When the protrusion is located at the end of the first section away from the second section, the cup lid is in the first state. When the protrusion moves along the second section of the sliding guide groove, the suction tube moves outward or inward along the perforation.

[0009] When the protrusion moves relative to the transmission component along the first section of the sliding guide groove, the suction tube will not extend or retract. At this point, the top of the suction tube is below the bottom surface of the upper cover and will not interfere with the rotation of the upper cover. As the protrusion moves along the first section, it either gradually covers the suction tube with the upper cover and eventually enters the first state, or it gradually removes the cover from the first state. The existence of the first section provides favorable conditions for optimizing the thickness of the upper cover, eliminating the need to take measures to avoid interference with the rotation of the upper cover caused by the suction tube. Such measures could include providing a recess on the bottom surface of the upper cover for clearance, or raising the distance between the bottom surface of the upper cover and the top surface of the cup lid base. Furthermore, the existence of the first section reduces the risk of accidental movement of the protrusion relative to the transmission component along the height direction (axial direction of the transmission component). Especially when a spring is used, this helps maintain the cup lid in the first state and reduces the possibility of accidental release from the first state.

[0010] In some embodiments, the sliding guide groove further includes a third section located at the same axial height as the transmission member, and the third section is connected to the higher end of the second section; when the protrusion moves along the third section of the sliding guide groove, the water suction pipe remains stationary relative to the perforation and always extends out of the upper cover.

[0011] By setting the third section, the risk of the protrusion moving unexpectedly relative to the transmission component along the height direction of the transmission component (transmission component axis) is reduced. Especially in the absence of a spring, this helps the suction pipe to remain extended from the upper cover and prevents it from retracting, thus reducing the possibility of the suction pipe retracting unexpectedly.

[0012] In some embodiments, the bottom of the cup lid base is provided with a closed cavity, and the protrusion of the water suction tube and the transmission component are both located in the closed cavity.

[0013] By creating a closed cavity, the protrusions and transmission components are isolated from the outside environment, preventing water, dust, and other contaminants from entering. This protects the components within the closed cavity, preventing contamination and facilitating cleaning of the cup lid. Without this closed cavity, dust, scale, and water can easily remain on the components, such as in the sliding guide groove, when cleaning the cup lid.

[0014] In some embodiments, the enclosed cavity includes a first chamber and a second chamber arranged adjacent to each other. The first chamber extends along the axial direction of the perforation, and the second chamber extends along the axial direction of the transmission member. A guide groove is formed on the adjacent portion of the first chamber and the second chamber. The first chamber communicates with the second chamber through the guide groove. The extension direction of the guide groove is parallel to the axial direction of the transmission member. The protrusion extends into the sliding guide groove through the guide groove. The protrusion and the guide groove form the limiting structure.

[0015] In some embodiments, the bottom of the closed cavity is provided with an opening, and a sealing cap is installed in the opening. The sealing cap has a through hole inside, which extends along the axial direction of the water suction pipe. A portion of the length of the water suction pipe is located in the through hole, and the water suction pipe moves relative to the through hole when it moves along the perforation.

[0016] In some embodiments, the suction tube is provided with a first shoulder; a spring is sleeved on the suction tube, the spring is located inside the closed cavity, one end of the spring abuts against the first shoulder, and the other end abuts against the sealing cap, the spring providing a force for the suction tube to move outward along the perforation.

[0017] By incorporating a spring, the suction tube is provided with a force that moves outward along the perforation, making it easier to extend the suction tube by rotating the top cover, thus improving the user experience. Furthermore, the spring reduces the risk of the protrusion accidentally moving relative to the transmission component along its height direction (transmission component axis), helping to keep the suction tube extended from the top cover and preventing it from retracting, thereby reducing the possibility of accidental retraction.

[0018] In some embodiments, a small-diameter hole is provided in the through hole, the bottom end of the water suction pipe is located in the through hole, and a sealing member is provided at the bottom end of the water suction pipe. The sealing member moves synchronously with the water suction pipe, and a connecting hole is opened on the side wall of the sealing member. The connecting hole is connected to the channel inside the water suction pipe. In the first state, the sealing member blocks the small-diameter hole. When the sealing member does not block the small-diameter hole, the channel inside the water suction pipe is connected to the small-diameter hole through the connecting hole.

[0019] By setting a small-diameter hole and a sealing element, the sealing element blocks the small-diameter hole in the first state, preventing water from entering the suction tube. This reduces the risk of water leakage from the suction tube in the first state and improves the overall sealing performance of the water cup when the cup lid is installed on the cup body.

[0020] In some embodiments, the end of the sealing member away from the water suction pipe is a cylindrical sealing head, which is adapted to the small-diameter hole. An annular protrusion is provided around the cylindrical sealing head on the sealing member; a second shoulder is provided on the outer periphery of the small-diameter hole, and an annular groove adapted to the annular protrusion is provided on the second shoulder around the small-diameter hole. Alternatively, an annular groove is provided around the cylindrical sealing head on the sealing member; a second shoulder is provided on the outer periphery of the small-diameter hole, and an annular protrusion adapted to the annular groove is provided on the second shoulder around the small-diameter hole. In the first state, the sealing head is located in the small-diameter hole and seals the small-diameter hole. At this time, the annular protrusion and the annular groove align, thus improving the sealing effect of the sealing member on the water suction pipe.

[0021] In some embodiments, the upper cover is integrally formed with the transmission component.

[0022] On the other hand, this application provides a water cup, including a body and the aforementioned water cup lid; the cup body and the lid base are detachably connected.

[0023] The water cup lid and water cup provided in this application have at least one of the following beneficial effects:

[0024] 1. This application provides a water cup lid with an ingenious design, novel structure, and unique opening method. The main differences between this application's water cup lid and existing technologies include: this application transforms the rotational movement of the upper lid body into the extension and retraction (translational) movement of the suction tube. By screwing on the upper lid body, the upper lid body drives the transmission component to rotate. The rotation of the transmission component causes the protrusion on the suction tube to move along the sliding guide groove. The movement of the protrusion can drive the entire suction tube to move vertically relative to the upper lid body. When the water cup lid is in the first state, the suction tube and the perforation are covered under the upper lid body, preventing contamination of the suction tube and the perforation, ensuring cleanliness and hygiene. When drinking water is needed, the suction tube can be extended from the upper lid body by screwing on the upper lid body in the first direction; when drinking water is not needed, the suction tube can be retracted back under the upper lid body by screwing on the upper lid body in the opposite direction of the first direction.

[0025] 2. The water cup lid provided in this application, when the protrusion moves relative to the transmission member along the first section of the sliding guide groove, the suction tube will not extend or retract. At this time, the top of the suction tube is already below the bottom surface of the upper lid, and will not interfere with the rotation of the upper lid. When the protrusion moves along the first section, it either causes the upper lid to gradually cover the suction tube and eventually enter the first state, or it causes the upper lid to gradually release the cover of the suction tube from the first state. The existence of the first section provides favorable conditions for optimizing the thickness of the upper lid, eliminating the need to take avoidance measures on the bottom surface of the upper lid to consider the interference caused by the suction tube to the rotation of the upper lid. Avoidance measures can be to provide a groove for clearance on the bottom surface of the upper lid, or to raise the distance between the bottom surface of the upper lid and the top surface of the lid base. In addition, the existence of the first section reduces the risk of the protrusion moving unexpectedly relative to the transmission member along the height direction of the transmission member (transmission member axis), especially when a spring is provided, which helps the water cup lid to remain in the first state and reduces the possibility of accidentally releasing the first state.

[0026] 3. The cup lid provided in this application reduces the risk of the protrusion moving unexpectedly relative to the transmission component along the height direction (axial direction of the transmission component) by setting a third section. Especially in the absence of a spring, it helps the suction tube to remain extended from the upper cover and prevents it from retracting, thus reducing the possibility of the suction tube retracting unexpectedly.

[0027] 4. The water cup lid provided in this application features a closed cavity that isolates the protrusion and transmission components from the outside environment. Water, dust, and other contaminants cannot enter the closed cavity, thus protecting the components within and preventing contamination, while facilitating cleaning of the water cup lid. Without this closed cavity, dust, scale, and water can easily remain on the components during cleaning, for example, in the sliding guide groove.

[0028] 5. The water cup lid provided in this application incorporates a spring. The spring provides a force that moves the suction tube outward along the perforation, making it easier to extend the suction tube by rotating the lid, thus improving the user experience. Furthermore, the presence of the spring reduces the risk of accidental movement of the protrusion relative to the transmission component along the height direction (axial direction of the transmission component), helping to keep the suction tube extended from the lid and preventing retraction, thereby reducing the possibility of accidental retraction.

[0029] 6. The water cup lid provided in this application, by setting a small diameter hole and a sealing component, in the first state, the sealing component blocks the small diameter hole, preventing water from entering the water suction tube, reducing the risk of water leakage from the water suction tube in the first state, and improving the overall sealing performance of the water cup when the water cup lid is installed on the cup body.

Detailed Implementation

[0048] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0049] To keep the drawings concise, each drawing only schematically shows the parts relevant to this application, and they do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0050] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0051] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0053] refer to Figures 1-13 , Figure 15 This application provides a water cup lid, including: a lid base 1, an upper lid body 2, a transmission component 3, and a suction tube 4; the outer wall of the suction tube 4 is provided with a protrusion 41; the lid base 1 is provided with a through hole 11, which is used to make way for the suction tube 4; a limiting structure is provided between the lid base 1 and the suction tube 4, which is used to prevent the suction tube 4 from rotating relative to the lid base 1; the upper lid body 2 is located on the upper end face of the lid base 1 and is adapted to rotate relative to the lid base 1 around its own axis, and an arc-shaped clearance groove 21 is provided on the upper lid body 2, which is used to make way for the suction tube 4; the transmission component 3 is located at the bottom of the upper lid body 2 and is coaxially arranged with the upper lid body 2, and is adapted to rotate synchronously with the upper lid body 2; the side wall of the transmission component 3 is provided with a sliding guide groove 31, and the protrusion 41 extends into the sliding guide groove 31; when the upper lid body 2 is screwed, the protrusion 41 moves along the sliding guide groove 31.

[0054] In the first state, both the perforation 11 and the suction tube 4 are covered under the upper cover 2. When the upper cover 2 is gradually screwed on in the first direction from the first state, the upper cover 2 first removes the cover from the perforation 11 and the suction tube 4. As the upper cover 2 is screwed on, the suction tube 4 moves outward along the perforation 11 and gradually extends out of the upper cover 2 through the relief groove 21. When the upper cover 2 is screwed on in the opposite direction from the first direction, the suction tube 4 first moves inward along the perforation 11. As the upper cover 2 is screwed on, the cup lid enters the first state.

[0055] Specifically, the upper cover 2 can be integrally formed with the transmission component 3, forming a single component, or it can be two independent components. When the upper cover 2 and the transmission component 3 are two independent components, the transmission component 3 is connected to the bottom of the upper cover 2. The connection method can be bonding, hot-melt welding, screwing, snap-fitting, etc. Figures 4-7, Figure 15 A specific connection method is shown: the bottom of the upper cover 2 is provided with a linkage part 22, and the top of the transmission component 3 is provided with a driven part 32 that matches the linkage part 22. When the upper cover 2 is installed on the cup lid base 1, the linkage part 22 and the driven part 32 are connected. When the upper cover 2 is screwed, the transmission component 3 rotates synchronously.

[0056] Understandably, to enable the upper lid 2 to rotate relative to the cup lid base 1, there are multiple options for the connection between the upper lid 2 and the cup lid base 1. For example, a sliding groove can be provided on the outer periphery of the cup lid base 1, and the upper lid 2 can have a downwardly extending annular outer edge. The inner side of the annular outer edge can have a protrusion that matches the sliding groove. The upper lid 2 can be fastened onto the upper end of the cup lid base 1, and the protrusion on the inner side of the annular outer edge can be engaged in the sliding groove of the cup lid base 1. When the upper lid 2 is screwed on, the protrusion on the inner side of the annular outer edge can slide along the sliding groove of the cup lid base 1. Alternatively, the upper lid 2 can have a downwardly extending annular outer edge, and a sliding groove on the inner side of the annular outer edge. The outer periphery of the cup lid base 1 can have a protrusion that matches the sliding groove. The upper lid 2 can be fastened onto the upper end of the cup lid base 1, and the protrusion on the outer periphery of the cup lid base 1 can be engaged in the sliding groove on the inner side of the annular outer edge.

[0057] The water cup lid of this application features an ingenious design, novel structure, and unique opening method. The main differences between this water cup lid and existing technologies include: this application transforms the rotational movement of the upper cover 2 into the extension and retraction (translational) movement of the suction tube 4. By screwing on the upper cover 2, the upper cover 2 drives the transmission component 3 to rotate. The rotation of the transmission component 3 causes the protrusion 41 on the suction tube 4 to move along the sliding guide groove 31. The movement of the protrusion 41 enables the entire suction tube 4 to move vertically relative to the upper cover 2. When the water cup lid is in the first state, the suction tube 4 and the perforation 11 are both covered under the upper cover 2, preventing contamination of the suction tube 4 and the perforation 11 and ensuring cleanliness and hygiene. When drinking water is needed, the suction tube 4 can be extended from the upper cover 2 by screwing on the upper cover 2 in the first direction; when drinking water is not needed, the suction tube 4 can be retracted back under the upper cover 2 by screwing on the upper cover 2 in the opposite direction of the first direction.

[0058] refer to Figures 4-6 , Figure 11 , Figure 12In one embodiment, the sliding guide groove 31 includes a first section 311 and a second section 312. The first section 311 is located at the same height along the axial direction of the transmission member 3, and the second section 312 is spirally distributed along the axial direction of the transmission member 3. The lower ends of the first section 311 and the second section 312 are connected. When the protrusion 41 moves along the first section 311 of the sliding guide groove 31, the water suction tube 4 remains stationary relative to the perforation 11. When the protrusion 41 is located at the end of the first section 311 away from the second section 312, the cup lid is in the first state. When the protrusion 41 moves along the second section 312 of the sliding guide groove 31, the water suction tube 4 moves outward or inward along the perforation 11.

[0059] It is easy to understand that when the protrusion 41 moves relative to the transmission member 3 along the first section 311 of the sliding guide groove 31, the suction pipe 4 will not extend or retract. At this time, the top of the suction pipe 4 is already below the bottom surface of the upper cover 2, and will not interfere with the rotation of the upper cover 2. When the protrusion 41 moves along the first section 311, it either causes the upper cover 2 to gradually cover the suction pipe 4 and eventually enter the first state, or it causes the upper cover 2 to gradually remove the cover from the first state. The existence of the first section 311 provides favorable conditions for optimizing the thickness of the upper cover 2. There is no need to take avoidance measures on the bottom surface of the upper cover 2 because of the interference caused by the suction pipe 4 to the rotation of the upper cover 2. Avoidance measures can be to set a groove on the bottom surface of the upper cover 2 for clearance, or to raise the distance between the bottom surface of the upper cover 2 and the top surface of the cup lid base 1. Furthermore, the presence of the first segment 311 reduces the risk of accidental movement of the protrusion 41 relative to the transmission member 3 along the height direction of the transmission member 3 (axial direction of the transmission member 3). Especially when the spring 5 is provided, it helps to keep the cup lid in the first state and reduces the possibility of accidental release of the first state. Specific embodiments of the spring 5 will be described below and will not be repeated in this section.

[0060] It should be noted that the first section 311 of the sliding guide groove 31 is not necessary. In one embodiment, the first section 311 may not be provided, but in order to avoid interference of the suction pipe 4 with the rotation of the upper cover 2, it is necessary to take measures to avoid the bottom surface of the upper cover 2. The avoidance measures may be to provide a groove for clearance on the bottom surface of the upper cover 2, or to increase the distance between the bottom surface of the upper cover 2 and the top surface of the cup lid base 1.

[0061] refer to Figures 4-6 , Figure 11 , Figure 12 In one embodiment, the sliding guide groove 31 further includes a third section 313, which is located at the same height in the axial direction of the transmission member 3. The third section 313 is connected to the end of the second section 312 located at the higher position. When the protrusion 41 moves along the third section 313 of the sliding guide groove 31, the water suction pipe 4 remains stationary relative to the perforation 11 and always extends out of the upper cover 2.

[0062] Understandably, by setting the third segment 313, the risk of the protrusion 41 moving unexpectedly relative to the transmission member 3 along the height direction of the transmission member 3 (axial direction of the transmission member 3) is reduced. In particular, in the absence of the spring 5, it is beneficial for the suction pipe 4 to remain extended from the upper cover 2 and not to retract, thus reducing the possibility of the suction pipe 4 retracting unexpectedly.

[0063] It should be noted that the third segment 313 of the sliding guide groove 31 is not mandatory. In one embodiment, the third segment 313 may be omitted, but to prevent the suction pipe 4 from remaining extended from the upper cover 2 and from retracting, and to reduce the possibility of accidental retraction of the suction pipe 4, a spring 5 can be used. Specific embodiments of the spring 5 will be described below and will not be repeated in this section.

[0064] refer to Figure 4 , Figure 5 , Figures 8-10 , Figure 15 In one embodiment, the bottom of the cup lid base 1 is provided with a closed cavity 12, and the protrusion 41 of the water suction tube 4 and the transmission component 3 are both located in the closed cavity 12.

[0065] By providing a closed cavity 12, the protrusion 41 and the transmission component 3 are isolated from the outside environment. Water, dust, and other contaminants cannot enter the closed cavity 12, thus protecting the components within it and preventing contamination. This also facilitates cleaning of the cup lid. Without the closed cavity 12, dust, scale, and water can easily remain on the components, such as in the sliding guide groove 31, when cleaning the cup lid.

[0066] refer to Figure 4 , Figure 5 , Figures 8-10 , Figure 15 In one embodiment, the enclosed cavity 12 includes a first chamber 121 and a second chamber 122 arranged adjacent to each other. The first chamber 121 extends along the axial direction of the perforation 11, and the second chamber 122 extends along the axial direction of the transmission member 3. A guide groove 123 is provided on the adjacent portion of the first chamber 121 and the second chamber 122. The first chamber 121 communicates with the second chamber 122 through the guide groove 123. The extending direction of the guide groove 123 is parallel to the axial direction of the transmission member 3. The protrusion 41 extends into the sliding guide groove 31 through the guide groove 123. The protrusion 41 and the guide groove 123 form a limiting structure.

[0067] It is understandable that the previous paragraph only described one specific form of the limiting structure. In fact, the limiting structure in this application can also be in other forms, such as: providing a guide groove on the wall of the closed cavity 12 (the position is different from the guide groove 123 in the previous paragraph), and providing a protrusion adapted to the guide groove at the corresponding position of the suction pipe 4 (the position is different from the protrusion 41 that extends into the sliding guide groove 31); or the guide groove is provided on the suction pipe 4, and the protrusion is provided on the wall of the closed cavity 12.

[0068] refer to Figure 4 , Figure 5 , Figure 7 , Figures 10-12 , Figure 15 In one embodiment, the bottom of the closed cavity 12 is provided with an opening 124, and a sealing cap 13 is installed inside the opening 124. The interior of the sealing cap 13 is a through hole 131, which extends axially along the water suction pipe 4. A portion of the length of the water suction pipe 4 is located in the through hole 131, and the water suction pipe 4 moves relative to the through hole 131 when it moves along the perforation 11. It should be noted that when the water suction pipe 4 is in the through hole 131, the two are in a sealed state, and water will not enter the closed cavity 12 through the through hole 131.

[0069] refer to Figure 4 , Figure 5 , Figure 12 , Figure 13 , Figure 15 In one embodiment, the suction pipe 4 is provided with a first shoulder 42; a spring 5 is provided on the outer sleeve of the suction pipe 4, the spring 5 is located in the closed cavity 12, one end of the spring 5 abuts against the first shoulder 42, and the other end abuts against the sealing cap 13, the spring 5 provides a force for the suction pipe 4 to move outward along the perforation 11.

[0070] It is worth noting that by setting spring 5, the suction tube 4 is provided with a force that moves outward along the perforation 11, making the process of rotating the upper cover 2 to extend the suction tube 4 easier and improving the user experience. In addition, the presence of spring 5 reduces the risk of the protrusion 41 moving unexpectedly relative to the transmission member 3 along the height direction of the transmission member 3 (axial direction of the transmission member 3), which helps the suction tube 4 to remain extended from the upper cover 2 and prevents it from retracting, thus reducing the possibility of the suction tube 4 retracting unexpectedly.

[0071] refer to Figure 4 , Figure 5 , Figures 13-15In one embodiment, a small-diameter hole 1311 is provided in the through hole 131, the bottom end of the water suction pipe 4 is located in the through hole 131, and a sealing member 6 is provided at the bottom end of the water suction pipe 4. The sealing member 6 moves synchronously with the water suction pipe 4, and a connecting hole 61131 is opened on the side wall of the sealing member 6. The connecting hole 61131 is connected to the channel inside the water suction pipe 4. In the first state, the sealing member 6 blocks the small-diameter hole 1311. When the sealing member 6 does not block the small-diameter hole 1311, the channel inside the water suction pipe 4 is connected to the small-diameter hole 1311 through the connecting hole 61.

[0072] Understandably, by setting the small diameter hole 1311 and the sealing component 6, the sealing component 6 blocks the small diameter hole 1311 in the first state, preventing water from entering the suction pipe 4, reducing the risk of water leakage from the suction pipe 4 in the first state, and improving the overall sealing performance of the water cup when the cup lid is installed on the cup body.

[0073] refer to Figures 13-15 In one embodiment, the end of the sealing member 6 away from the water suction pipe 4 is a cylindrical sealing head 62, which is adapted to the small-diameter hole 1311. An annular protrusion is provided on the sealing member 6 around the cylindrical sealing head 62; a second shoulder 132 is provided on the outer periphery of the small-diameter hole 1311, and an annular groove adapted to the annular protrusion is provided on the second shoulder 132 around the small-diameter hole 1311. Alternatively, an annular groove 63 is provided on the sealing member 6 around the cylindrical sealing head 62; a second shoulder 132 is provided on the outer periphery of the small-diameter hole 1311, and an annular protrusion 1321 adapted to the annular groove 63 is provided on the second shoulder 132 around the small-diameter hole 1311. In the first state, the plug head 62 is located in the small diameter hole 1311 and blocks the small diameter hole 1311. At this time, the annular protrusion 1321 is connected with the annular groove 63, thus improving the sealing effect of the plug 6 on the water suction pipe 4.
