Description

Technical Field

[0001] This invention relates to the field of daily necessities technology, and in particular to a pop-up cup lid and a water cup. Background Technology

[0002] A thermos is a common household item. The lid of a thermos is usually a pop-up lid. To use it, press the control button once to open the water outlet, and press the control button again to close the water outlet.

[0003] To achieve the aforementioned press-and-release opening and closing function, the spring-loaded cup lid in related technologies typically includes a cup lid body, an operating component, a sealing component, a fixing component, a movable component, a lock, and a resilient reset component. The cup lid body has a water outlet channel. The operating component is located on the outside of the cup lid body for user operation and can move up and down relative to the cup lid body. The sealing component is located on the inside of the cup lid body and connected to the operating component, used to open or close the water outlet channel. The fixing component is mounted on the cup lid body and has a first toothed structure. The movable component can move up and down relative to the cup lid body and has a second toothed structure. The lock is fitted onto the operating component and can move up and down with the operating component; the lock has a third toothed structure. The resilient reset component is used to drive the operating component to reset after it is pressed. During the up and down movement of the lock, the third toothed structure rotates in conjunction with the first toothed structure of the fixing component and the second toothed structure of the movable component, thereby locking the sealing component in the sealing position or unlocking it. In other words, the relevant technology requires the cooperation of the lock, the fixing part, and the moving part to lock and unlock the sealing component. There are many parts, the assembly efficiency is low, and the cooperation of multiple parts is prone to the accumulation of assembly errors, which ultimately leads to the opening and closing process being unsmooth and affecting the user experience.

[0004] Therefore, there is an urgent need for a pop-up cup lid and cup to solve the above-mentioned technical problems. Summary of the Invention

[0005] One objective of this invention is to provide a pop-up cup lid that can not only open with a single press and close with a second press, but also has fewer parts, resulting in lower cost, higher assembly efficiency, and smaller cumulative assembly errors, thus ensuring smooth opening and closing.

[0006] To achieve this objective, the present invention adopts the following technical solution: A pop-up cup lid, comprising: The cup lid body has a water outlet channel and an installation channel. The inner wall of the installation channel has a mating protrusion along the circumference. The upper surface of the mating protrusion is constructed with multiple evenly distributed toothed grooves. The toothed grooves include a first V-shaped toothed groove and a second V-shaped toothed groove arranged adjacent to each other. The mating protrusion has a vertically penetrating slide at the second V-shaped toothed groove. The lower end of the mating protrusion has a slot structure. An operating component is disposed on the outside of the cup lid body and can slide up and down relative to the cup lid body; A sealing assembly includes a sealing part and a mounting shaft. The sealing part is disposed inside the cup lid body and is used to seal the inner end of the water outlet channel. The mounting shaft passes through the mounting channel and is connected to the operating component. A locking component is sleeved on the mounting shaft and can rotate relative to the mounting shaft. The upper end of the outer peripheral surface of the locking component has multiple upper locking teeth evenly distributed along the circumferential direction, and the lower end of the outer peripheral surface of the locking component has multiple lower locking teeth evenly distributed along the circumferential direction. An elastic reset element is configured to drive the operating element to reset after the operating element is pressed. When the sealing part blocks the inner end of the water outlet channel, each of the lower locking teeth is located in a corresponding slide. When the operating member is pressed once, the upper locking tooth slides into the first groove wall of the first V-shaped tooth groove, so as to drive the locking member to rotate in the first direction until each of the lower locking teeth can lock with a corresponding slot structure. When the operating member is pressed a second time, the upper locking tooth slides into the second groove wall of the second V-shaped tooth groove, and can drive the locking member to rotate in the first direction until the lower locking tooth unlocks the slot structure.

[0007] As an optional solution, the top surface of the lower locking tooth is a first inclined surface, the slot structure includes a slot portion and a boss portion arranged circumferentially, the bottom surface of the slot portion is a second inclined surface, and the bottom surface of the boss portion is a third inclined surface; When the operating member is reset after the elastic reset member is pressed once, the second inclined surface slides with the first inclined surface to drive the locking member to rotate in the first direction until the lower locking tooth abuts against the boss in the circumferential direction, and the lower end of the upper locking tooth is vertically opposite to the second groove wall. When the operating member is reset after being driven by the elastic reset member to press twice, the third inclined surface slides with the first inclined surface to drive the lock member to rotate in the first direction until the lower locking tooth enters the adjacent slide, and the lower end of the upper locking tooth is vertically opposite to the first groove wall of the adjacent tooth groove structure.

[0008] As an optional solution, the mounting shaft includes a first shaft portion and a second shaft portion. The first shaft portion is connected to the sealing portion, and the second shaft portion is connected to the end of the first shaft portion away from the sealing portion. A first annular locking protrusion is provided on the outer periphery of the end of the second shaft portion away from the first shaft portion. The locking member is sleeved on the second shaft portion, with one end of the locking member abutting against the first shaft portion. A second annular locking protrusion is provided on the inner circumferential surface of the other end of the locking member. The first annular locking protrusion axially stops the second annular locking protrusion.

[0009] As an alternative, the second annular protrusion is provided with a notch along its circumferential direction.

[0010] As an optional solution, the outer side of the cup lid body is provided with a mounting groove, and the cup lid body also includes a mounting cylinder, the mounting cylinder passing through the bottom of the mounting groove, the mounting cylinder forming the mounting channel, and the mounting shaft passing through the mounting cylinder; the operating member is slidably disposed in the mounting groove, and the bottom plate of the mounting groove is configured to axially limit the operating member.

[0011] As an optional solution, the inner wall of the mounting cylinder facing the sealing part is provided with a connecting groove. When the water outlet channel is opened by the sealing part, one end of the connecting groove communicates with the inner side of the cup lid body, and the other end communicates with the outer side of the cup lid body through the gap between the mounting cylinder and the locking member; and / or A sealing ring is fitted around the circumference of the mounting shaft. When the sealing part blocks the water outlet channel, the sealing ring seals the gap between the mounting shaft and the inner wall of the mounting cylinder.

[0012] As an optional solution, the elastic reset element is disposed between the cup lid body and the operating element; or The elastic reset element is disposed between the cup lid body and the sealing assembly.

[0013] As an optional solution, the lock element is integrally injection molded; and / or The operating component is threadedly connected to the mounting shaft.

[0014] As an optional solution, the cup lid body includes a lower lid and an upper lid. The lower lid is cylindrical, and the upper lid is installed on the upper end of the lower lid. The upper lid is inserted into the lower lid and forms a gap between them. The upper lid is provided with a water outlet hole. The gap communicates with the water outlet hole and forms the water outlet channel. The sealing part can open or block the lower end of the gap.

[0015] Another objective of this invention is to provide a water cup that, by adopting the aforementioned pop-up lid, is low in cost, has smooth opening and closing with a press, and provides a good user experience.

[0016] To achieve this objective, the present invention adopts the following technical solution: A water cup includes a cup body and a spring-loaded lid, the spring-loaded lid being able to cover the cup body.

[0017] The beneficial effects of this invention are: The spring-loaded cup lid of the present invention includes a cup lid body, an operating component, a sealing component, a locking component, and an elastic reset component. The operating component is disposed on the outer side of the cup lid body. The sealing part of the sealing component is disposed on the inner side of the cup lid body and is used to seal the inner end of the water outlet channel. The mounting shaft of the sealing component passes through the mounting channel and is connected to the operating component. The locking component is sleeved on the mounting shaft and can rotate relative to the mounting shaft. When the user presses the operating component, the operating component, the sealing component, and the locking component move synchronously. The elastic reset component is used to drive the operating component to reset after it is pressed. The inner wall of the mounting channel of the cup lid body is provided with a mating protrusion. The upper end surface of the mating protrusion is constructed with multiple evenly distributed toothed groove structures. The toothed groove structure includes adjacent first V-shaped toothed grooves and second V-shaped toothed grooves. The mating protrusion is provided with a slide extending axially along the cup lid body at the second V-shaped toothed groove. The lower end of the mating protrusion is provided with a slot structure. Multiple upper locking teeth are evenly distributed circumferentially at the upper end of the outer peripheral surface of the lock, and multiple lower locking teeth are evenly distributed circumferentially at the lower end of the outer peripheral surface of the lock. When the sealing part blocks the inner end of the water outlet channel (i.e., the initial state), each lower locking tooth is located in a corresponding slide. When the operating part is pressed once, the lower locking tooth moves downward along the corresponding slide. After the lower locking tooth moves downward away from the slide, the lower end of the upper locking tooth contacts the first groove wall of the first V-shaped tooth groove and slides along the first groove wall, so that the entire lock moves downward while rotating in the first direction. At this time, each lower locking tooth is vertically opposite to a slot structure. When the operating part is released, the elastic reset part drives the operating part, the sealing component and the lock to move upward synchronously. At this time, each lower locking tooth is locked with the corresponding slot structure, and the position of the sealing component is lower than the initial state, thus opening the inner end of the water outlet channel. When the operating component is pressed a second time, the lower end of the upper locking tooth contacts the second groove wall of the second V-shaped tooth groove and slides along the second groove wall, thereby causing the entire locking component to move downwards while rotating in the first direction. At this time, each lower locking tooth unlocks with the corresponding slot structure. When the operating component is released, the elastic reset component drives the operating component, the sealing component, and the locking component to move upwards synchronously until the entire cup lid returns to its initial state. In other words, the spring-loaded cup lid of the present invention achieves the function of pressing and spring-loaded opening and closing by setting a mating protrusion in the installation channel of the cup lid body, with the upper end face of the mating protrusion forming a tooth groove structure, the lower end face forming a slot structure, and setting a vertically penetrating slide, and setting upper locking teeth and lower locking teeth at the upper and lower ends of the locking component, respectively. It has fewer parts, lower cost, higher assembly efficiency, and smaller cumulative assembly error, which makes it easier to ensure the smoothness of the opening and closing process.

[0018] Another objective of this invention is to provide a water cup, including a cup body and the aforementioned pop-up lid, which has low overall cost, smooth opening and closing with pressing, and a good user experience. Attached Figure Description

[0026] This embodiment provides a double-drinking cup lid and a water cup. The water cup includes a cup body and a double-drinking cup lid. The cup body is a cylindrical structure with an open top, and the double-drinking cup lid is placed over the opening of the cup body. It is understood that, without departing from the inventive concept of this application, the specific shape and size of the cup body can be flexibly set as needed, and are not specifically limited here. Optionally, in this embodiment, the water cup can be a thermos cup.

[0027] like Figures 1-3As shown, the pop-up cup lid includes a lid body 10, an operating component 20, a sealing assembly 30, a locking component 40, and an elastic reset component 50. The lid body 10 is used to connect to the cup body. The lid body 10 is provided with a water outlet channel 101 and an installation channel 1121. One end of the water outlet channel 101 communicates with the inside of the cup body, and the other end communicates with the outside of the lid body 10, for water outlet. The installation channel 1121 is used to install the operating component 20, the sealing assembly 30, and the locking component 40, etc. Specifically, the operating component 20 is located on the outside of the lid body 10 and is used for user pressing operation. The operating component 20 can slide up and down relative to the lid body 10. In this embodiment, the up and down direction is the axial direction of the lid body 10. The sealing assembly 30 includes a sealing part 31 and a mounting shaft 32. The sealing part 31 is located inside the cup lid body 10 and is used to seal the inner end of the water outlet channel 101. The mounting shaft 32 is connected to the sealing part 31, passes through the mounting channel 1121, and is connected to the operating member 20. The locking member 40 is sleeved on the mounting shaft 32 and can rotate relative to the mounting shaft 32. The locking member 40 extends at least partially into the mounting channel 1121. That is, when the user presses the operating member 20, the operating member 20, the locking member 40, and the sealing assembly 30 move up and down synchronously. The elastic reset member 50 is used to drive the operating member 20 to reset after it is pressed.

[0028] like Figure 4 As shown, the inner wall of the mounting channel 1121 is provided with a mating protrusion 113 along the circumferential direction. The upper end surface of the mating protrusion 113 is constructed with multiple evenly distributed toothed groove structures 114. The toothed groove structure 114 includes a first V-shaped toothed groove 1141 and a second V-shaped toothed groove 1142 arranged adjacently. The mating protrusion 113 is provided with a vertically penetrating slide 115 at the second V-shaped toothed groove 1142, and the lower end of the mating protrusion 113 is provided with a slot structure 116. Figure 5 As shown, multiple upper locking teeth 42 are evenly distributed circumferentially at the upper end of the outer peripheral surface of the lock member 40, and multiple lower locking teeth 43 are evenly distributed circumferentially at the lower end of the outer peripheral surface of the lock member 40. Figure 2 and Figure 6 As shown, when the sealing part 31 blocks the inner end of the water outlet channel 101 (defined as the initial state of the pop-up cup lid), each lower locking tooth 43 is located in a corresponding slide 115, and the upper locking tooth 42 is located directly above the first groove wall 1143 of the first V-shaped groove 1141; as Figure 7 As shown, when the operating member 20 is pressed once, the lower locking tooth 43 first moves downward along the corresponding slide 115. After the lower locking tooth 43 moves downward away from the slide 115, the lower end of the upper locking tooth 42 contacts the first groove wall 1143 of the first V-shaped tooth groove 1141 and slides along the first groove wall 1143, so that the entire locking member 40 moves downward while rotating in the first direction until each lower locking tooth 43 is vertically aligned with a corresponding slot structure 116; as Figure 3 and Figure 8As shown, when the operating component 20 is released, the elastic reset component 50 drives the operating component 20, the sealing component 30, and the locking component 40 to move upward synchronously. At this time, each lower locking tooth 43 is locked with the corresponding slot structure 116, and the sealing component 30 opens the inner end of the water outlet channel 101. Figure 9 As shown, when the operating member 20 is pressed a second time, the lower end of the upper locking tooth 42 contacts the second groove wall 1144 of the second V-shaped tooth groove 1142 and slides along the second groove wall 1144, thereby causing the entire lock member 40 to move downwards while rotating in the first direction. At this time, each lower locking tooth 43 unlocks with the corresponding slot structure 116. When the operating member 20 is released, the elastic reset member 50 drives the operating member 20, the sealing component 30, and the lock member 40 assembly to move upwards synchronously until the entire pop-up cup cover returns to its original position. Figure 6 The state shown.

[0029] In other words, the pop-up cup lid of this embodiment can realize the function of pressing and popping open and close by setting a mating protrusion 113 in the installation channel 1121 of the cup lid body 10, and forming a toothed groove structure 114 on the upper end surface and a slot structure 116 on the lower end surface of the mating protrusion 113, as well as setting a vertically penetrating slide 115, and setting an upper locking tooth 42 and a lower locking tooth 43 on the upper and lower ends of the locking member 40, respectively. The number of parts is small, which not only reduces the cost and increases the assembly efficiency, but also reduces the cumulative assembly error, making it easy to ensure the smoothness of the opening and closing process.

[0030] It should be noted that in this embodiment, a single press can be understood as an odd number of presses, after which the water inlet channel is opened. A double press can be understood as an even number of presses, after which the water inlet channel is closed. Of course, the number of upper locking teeth 42, the number of lower locking teeth 43, the number of upper tooth groove structures 114 of the cooperating protrusion 113, the number of slides 115, and the number of slot structures 116 are all equal.

[0031] like Figure 1 As shown, the cup lid body 10 has a circular overall structure, with screw threads on its outer circumference and internal threads on the inner side of the cup opening. Inserting the cup lid body 10 into the cup opening and screwing it in achieves a spring-loaded connection between the lid and the cup, which is not only convenient to operate but also provides a good seal. Of course, in other embodiments, the cup lid body 10 can also be connected to the cup body via a snap-fit ​​mechanism; this is not a limitation here.

[0032] like Figure 2 and Figure 3As shown, the cup lid body 10 includes a lower lid 12 and an upper lid 11, with the lower lid 12 having a cylindrical structure. The upper lid 11 is installed on the upper end of the lower lid 12, with a portion of the upper lid 11 inserted into the lower lid 12, forming a gap 118 between them. The upper lid 11 is provided with a water outlet hole 111, and the gap 118 communicates with the water outlet hole 111 to form a water outlet channel 101. The sealing part 31 can open or block the lower end of the gap 118, thereby realizing the opening and blocking of the entire water outlet channel 101. In this embodiment, an annular rib 121 is provided on the inner side of the lower lid 12, and the annular rib 121 has a funnel-shaped structure. The lower end of the annular rib 121 forms the inlet of the water outlet channel 101 between it and the upper lid 11.

[0033] like Figure 5 As shown, the lock 40 includes a lock body 41, which has a cylindrical structure and is fitted onto the mounting shaft 32. Upper locking teeth 42 and lower locking teeth 43 are both located on the outer circumferential surface of the lock body 41. The upper locking teeth 42 have a V-shaped structure. When the operating member 20 is pressed and the lock 40 moves downward, when the lower tip of the upper locking teeth 42 contacts the first groove wall 1143 / second groove wall 1144, the first groove wall 1143 / second groove wall 1144 guides the upper locking teeth 42 to rotate, thus causing the entire lock 40 to rotate. When the lower end of the upper locking teeth 42 contacts the bottom of the first V-shaped groove 1141 / second V-shaped groove 1142, the lock 40 will no longer rotate. Optionally, the entire lock 40 is integrally injection molded. This design ensures the positional accuracy between each upper locking tooth 42, the positional accuracy between each lower locking tooth 43, and the positional accuracy between the upper locking tooth 42 and the lower locking tooth 43, thereby ensuring the smoothness of the entire pop-up cup cover pressing operation after assembly.

[0034] like Figure 4 and Figure 5 As shown, the top surface of the lower locking tooth 43 is a first inclined surface 431, and the slot structure 116 includes a slot portion 1161 and a boss portion 1162 arranged circumferentially. The bottom surface of the slot portion 1161 is a second inclined surface 1163, and the bottom surface of the boss portion 1162 is a third inclined surface 1164. Figure 7 and Figure 8 As shown, when the operating member 20 is reset after being pressed once by the elastic reset member 50, the second inclined surface 1163 slides and engages with the first inclined surface 431, driving the locking member 40 to rotate in the first direction. This causes the lower locking tooth 43 to abut against the boss portion 1162 circumferentially, and the lower end of the upper locking tooth 42 to be vertically aligned with the second groove wall 1144. In other words, the engagement of the first inclined surface 431 and the second inclined surface 1163 ensures that after a single press, during the reset process of the operating member 20 driven by the elastic reset member 50, the upper locking tooth 42 of the locking member 40 can rotate to directly above the second groove wall 1144, so that the locking member 40 can continue to rotate in the first direction based on the guidance of the second groove wall 1144 during a second press. Figure 9 , Figure 6 As shown, when the operating member 20 moves upward to reset after being driven by the elastic reset member 50 to perform a second press, the third inclined surface 1164 slides and engages with the first inclined surface 431, driving the locking member 40 to rotate in the first direction. This causes the lower locking tooth 43 to enter the adjacent slide rail 115, and the lower end of the upper locking tooth 42 to be vertically aligned with the first groove wall 1143 of the adjacent tooth groove structure 114. In other words, the engagement of the second inclined surface 1163 and the third inclined surface 1164 ensures that after the second press, during the process of the elastic reset member 50 driving the operating member 20 to reset, the upper locking tooth 42 of the locking member 40 can rotate to directly above the first groove wall 1143 of the adjacent first V-shaped tooth groove 1141, and the lower locking tooth 43 can enter the adjacent slide rail 115. This allows the locking member 40 to rotate in the first direction based on the guidance of the first groove wall 1143 when the next press is performed.

[0035] In summary, the working principle of the pop-up cup lid is roughly as follows: like Figure 2 and Figure 6 As shown, in the initial state where the sealing part 31 blocks the inner end of the water outlet channel 101, each lower locking tooth 43 is located in a corresponding slide 115, and each upper locking tooth 42 is located directly above the first groove wall 1143 of a first V-shaped groove 1141; as Figure 7 As shown, when the operating member 20 is pressed once, the lower locking tooth 43 first moves downward along the corresponding slide 115. After the lower locking tooth 43 moves downward away from the slide 115, the lower end of the upper locking tooth 42 contacts the first groove wall 1143 of the first V-shaped tooth groove 1141 and slides along the first groove wall 1143 until the lower end of the upper locking tooth 42 reaches the bottom of the first V-shaped tooth groove 1141. During this process, the entire locking member 40 moves downward while rotating at a first angle in the first direction. At this time, each lower locking tooth 43 corresponds to the slot part 1161 of a slot structure 116, which is vertically opposite to the slot part 1161.

[0036] like Figure 3 and Figure 8As shown, when the operating member 20 is released, the elastic reset member 50 drives the operating member 20, the sealing assembly 30, and the locking member 40 to move upward synchronously. During this process, the first inclined surface 431 of the lower locking tooth 43 contacts the second inclined surface 1163 of the slot portion 1161. Under the guidance of the second inclined surface 1163, the lower locking tooth 43 and the entire locking member 40 continue to rotate a second angle along the first direction until the lower locking tooth 43 abuts against the boss portion 1162 circumferentially. At this time, the lower end of the upper locking tooth 42 rotates to the top of the second groove wall 1144 of the second V-shaped tooth groove 1142. The cooperation between the lower locking tooth 43 and the slot structure 116 realizes the position locking of the locking member 40 and also realizes the opening of the water outlet channel 101 of the sealing assembly 30. The water in the cup can enter the interval 118 through the opening between the sealing assembly 30 and the annular rib plate 121 and then be discharged from the water outlet hole 111.

[0037] like Figure 9 As shown, when the operation component 20 is pressed for the second time, the entire locking component 40 moves downward. During this process, the lower locking tooth 43 first separates from the slot structure 116 in the vertical direction. Then, the lower end of the upper locking tooth 42 contacts the second groove wall 1144 of the second V-shaped groove 1142 and slides along the second groove wall 1144 until the lower end of the upper locking tooth 42 reaches the bottom of the second V-shaped groove 1142. During this process, the entire locking component 40 moves downward while rotating at a third angle along the first direction. At this time, the first inclined surface 431 of each lower locking tooth 43 is vertically opposite to the third inclined surface 1164 of the boss portion 1162, thus unlocking the lower locking tooth 43 from the slot structure 116.

[0038] When the operating member 20 is released, the elastic reset member 50 drives the operating member 20, the sealing component 30, and the locking component 40 to move upward synchronously. During this process, the first inclined surface 431 of the lower locking tooth 43 moves upward to contact the third inclined surface 1164 of the boss portion 1162. Guided by the third inclined surface 1164, the entire locking component 40 moves upward while rotating at a fourth angle along the first direction until the first inclined surface 431 separates from the third inclined surface 1164. At this time, the lower locking tooth 43 is vertically aligned with the adjacent slide rail 115, and the lower end of the upper locking tooth 42 is located above the first groove wall 1143 of the adjacent first V-shaped groove 1141. Finally, the operating member 20, the sealing component 30, and the locking component 40 move upward as a whole under the action of the elastic reset member 50. Figure 6 The initial state is shown.

[0039] In other words, after one press and two presses, the upper locking tooth 42 rotates along the first direction by the arc between two adjacent tooth groove structures 114, and the lower locking tooth 43 rotates along the first direction by the arc between two adjacent slides 115.

[0040] like Figure 2 and Figure 4As shown, a mounting groove 117 is provided on the outer side of the cup lid body 10. The cup lid body 10 also includes a mounting cylinder 112, which penetrates the bottom of the mounting groove 117, forming a mounting channel 1121. A protrusion 113 is provided on the inner wall of the mounting cylinder 112. In this embodiment, the mounting groove 117 is provided on the upper cover 11, and the mounting cylinder 112 is also part of the upper cover 11. Figure 2 and Figure 7 As shown, the operating member 20 is slidably disposed within the mounting groove 117, and the mounting shaft 32 passes through the mounting cylinder 112 to connect with the operating member 20. The bottom plate 1171 of the mounting groove 117 is configured to axially limit the operating member 20. That is to say, the mounting groove 117 not only serves to accommodate the operating member 20, ensuring the aesthetics of the pop-up cup lid, but also limits the stroke of the operating member 20, ensuring reliable locking or unlocking after each press. In this embodiment, the operating member 20 is roughly a cap-shaped structure, and the inner cavity of the operating member 20 can accommodate part of the locking member 40, thereby making the entire pop-up cup lid structure compact.

[0041] like Figure 2 As shown, the elastic reset member 50 is a spring. In this embodiment, the elastic reset member 50 is disposed between the cup lid body 10 and the operating member 20. Specifically, as shown... Figure 2 and Figure 4 As shown, the top of the mounting cylinder 112 is provided with an annular protrusion 1123. One end of the elastic reset member 50 is sleeved on the annular protrusion 1123, and the other end abuts against the inner wall of the operating member 20, ensuring the reliability of the installation of the elastic reset member 50. Of course, in other embodiments, the elastic reset member 50 can also be disposed between the cup lid body 10 and the sealing assembly 30.

[0042] like Figure 2 and Figure 10 As shown, the sealing part 31 of the sealing assembly 30 includes a sealing plate 311 and a sealing gasket 312. The sealing plate 311 is made of a rigid material, giving the sealing part 31 sufficient rigidity. The sealing gasket 312 is made of a flexible material such as rubber. The sealing gasket 312 can abut against the lower end of the annular rib plate 121 of the lower cover 12, thereby ensuring the reliability of the seal on the water outlet channel 101. In this embodiment, the sealing gasket 312 is constructed as annular.

[0043] like Figure 5 , Figure 10 and Figure 11As shown, the mounting shaft 32 of the sealing assembly 30 includes a first shaft portion 321 and a second shaft portion 322. The first shaft portion 321 is connected to the sealing portion 31, and the second shaft portion 322 is connected to the end of the first shaft portion 321 opposite to the sealing portion 31. A first annular locking protrusion 324 is provided on the outer periphery of the end of the second shaft portion 322 opposite to the first shaft portion 321. The locking member 40 is sleeved on the second shaft portion 322, with one end of the locking member 40 abutting against the first shaft portion 321. A second annular locking protrusion 44 is provided on the inner circumferential surface of the other end of the locking member 40. The first annular locking protrusion 324 stops the second annular locking protrusion 44 axially. In other words, the axial limiting of each other can be achieved through the structural cooperation of the mounting shaft 32 and the locking member 40, which is simple in structure and reliable in limiting. During actual assembly, after the locking piece 40 is fitted onto the mounting shaft 32 and pressed down, the second annular locking protrusion 44 of the locking piece 40 passes over the first annular locking protrusion 324, thus realizing the assembly of the locking piece 40 and the sealing component 30.

[0044] like Figure 5 As shown, the second annular protrusion 44 has a notch 45 along its circumference. The notch 45 increases the elastic deformation capacity of the upper end of the locking member 40, thereby making the assembly process of the locking member 40 and the sealing assembly 30 smoother. Optionally, there can be two notches 45. In other embodiments, the number and shape of the notches 45 can be flexibly set.

[0045] like Figure 10 As shown, a slot 3221 is provided circumferentially on the second shaft portion 322. The slot 3221 reduces the mating area between the second shaft portion 322 and the locking member 40, thereby reducing the rotational resistance of the locking member 40 and further improving the smoothness of the pressing operation. In this embodiment, after the slot 3221 is completed on the second shaft portion 322, its cross-section is approximately cross-shaped. Of course, in other embodiments, the number and position of the slots 3221 can be flexibly set, and no specific limitation is made here.

[0046] like Figure 2 As shown, the operating component 20 is threadedly connected to the mounting shaft 32. This configuration allows for easy disassembly of the sealing assembly 30 and the operating component 20, facilitating the cleaning of the components of the pop-up cup lid and the interior of the cup lid body 10, thus improving the user experience. Specifically, as... Figure 10 and Figure 12 As shown, the mounting shaft 32 also includes a threaded portion 323, which is connected to one end of the second shaft portion 322 that is away from the first shaft portion 321. Correspondingly, a mounting post 21 protrudes from the inner side of the operating member 20, and an internal threaded hole 22 is provided on the mounting post 21, with the threaded portion 323 threadedly engaging with the internal threaded hole 22.

[0047] like Figure 2 and Figure 11As shown, a sealing ring 60 is fitted around the circumference of the mounting shaft 32. When the sealing part 31 blocks the water outlet channel 101, the sealing ring 60 seals the gap between the mounting shaft 32 and the inner wall of the mounting cylinder 112, thereby ensuring the sealing performance of the entire pop-up cup lid. In this embodiment, the sealing ring 60 is fitted onto the first shaft part 321. Optionally, a groove can be formed on the circumferential surface of the first shaft part 321 to limit the sealing ring 60. Optionally, the sealing ring 60 can be a rubber ring, and the specific cross-sectional shape of the sealing ring 60 can be flexibly set according to actual needs, and is not limited here.

[0048] like Figure 3 and Figure 13 As shown, the inner wall of the end of the mounting cylinder 112 facing the sealing part 31 is provided with a connecting groove 1122. When the water outlet channel 101 is opened in the sealing part 31, the sealing ring 60 descends to a position lower than the highest point of the connecting groove 1122. At this time, one end of the connecting groove 1122 is connected to the inner side of the cup lid body 10, and the other end is connected to the outer side of the cup lid body 10 through the gap between the mounting cylinder 112 and the locking piece 40. With this configuration, when the water outlet channel 101 is open, an air passage is formed that connects the inside and outside of the cup, thereby ensuring that the air pressure inside the cup is balanced with the external atmospheric pressure during drinking, thus ensuring smooth drinking and improving the user experience.

[0049] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, based on the concept of the present invention, there will be changes in specific implementation methods and application scope. The content of this specification should not be construed as a limitation of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the claims of the present invention.
