Description

Technical Field

[0001] This utility model relates to the field of water cup technology, specifically to a water cup lid with mechanical venting function. Background Technology

[0002] In daily use of water cups, especially when using insulated cups or cups containing carbonated beverages, a common problem arises: the steam generated by the hot water or the gas released from the carbonated beverage causes the pressure inside the cup to gradually increase. When the user attempts to open the lid, this increased pressure is often released suddenly, causing a "bang" sound, and may even cause the carbonated beverage to spray out, which is both inconvenient and unsafe.

[0003] To address this issue, some water bottle lid designs with venting functions have emerged on the market. However, these designs often suffer from drawbacks such as complex structure, inconvenient operation, or poor venting performance. For example, some designs employ complex electronic control mechanisms to achieve the venting function, which not only increases manufacturing costs but may also lead to venting failure due to electronic component malfunctions. Other designs may suffer from poorly designed venting channels, resulting in inadequate venting or incomplete sealing, affecting the water bottle's heat retention and user experience. Utility Model Content

[0004] The purpose of this invention is to provide a water cup lid with a mechanical venting function, in order to address the problems mentioned in the background section regarding the existence of water cup lid designs with venting functions on the market. However, these designs often suffer from drawbacks such as complex structure, inconvenient operation, or poor venting effect.

[0005] To achieve the above objectives, this utility model provides a water cup lid with a mechanical venting function, comprising a lid body, an upper lid and a lower lid, a central circular groove in the middle of the upper lid, a venting structure installed in the central circular groove, the venting structure including a venting switch, the side of the venting switch being rotatably connected to the inner wall of the central circular groove via a pin, a snap-fit ​​cover at the bottom of the venting switch, a small mushroom head at the bottom of the snap-fit ​​cover, and a sealing element made of silicone material installed at the bottom of the central circular groove. When the outer side of the venting switch is pulled upwards, the small mushroom head is pressed downwards by the lever action on the other side, causing the small mushroom head to disengage from the sealing element, thereby releasing the internal pressure.

[0006] Preferably, the upper and lower cup lids are rotatably connected on one side by a hinge, and the other side is engaged by a snap-fit ​​connection.

[0007] Preferably, the inner wall of the central circular groove is provided with a vertical guide strip, and the outer wall of the snap-fit ​​cover is provided with a guide groove, which slides vertically with the guide strip.

[0008] Preferably, the snap-fit ​​cover has a through hole in the middle, and the inner wall of the through hole has a snap-fit ​​inlet and a snap-fit ​​position. The top of the small mushroom head is provided with a snap-fit ​​block. The top of the small mushroom head passes through the through hole in the middle of the snap-fit ​​cover. The snap-fit ​​block rotates 90 degrees after passing through the snap-fit ​​inlet and cooperates with the snap-fit ​​position.

[0009] Preferably, the small mushroom head includes a stem and an end, with an opening in the center of the bottom of the central circular groove, the stem of the small mushroom head slidingly engaging with the opening vertically, and the end of the small mushroom head fitting against the bottom outer side of the opening.

[0010] Preferably, a spring is provided inside the central circular groove. The spring is wound around the outside of the stem of the mushroom head. The bottom of the spring abuts against the inner wall of the central circular groove, and the top abuts against the bottom surface of the snap-fit ​​cover.

[0011] Preferably, a sealing protrusion is integrally formed on the bottom surface of the seal, and the end of the mushroom head abuts against the sealing protrusion.

[0012] Preferably, a groove is provided on the outer side of the bottom of the central circular groove, and an annular retaining strip is provided on the inner wall of the seal, the annular retaining strip engaging with the groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This water cup lid with mechanical venting function utilizes a mechanical venting structure to safely release internal pressure. When the user needs to release pressure, simply pull up the vent switch; the lever action disengages the small mushroom-shaped nozzle from the seal, allowing internal gas to escape smoothly. This effectively avoids noise and spillage caused by sudden pressure release when opening the lid, thus improving safety.

[0015] The venting mechanism is compactly installed within the central circular groove, taking up no extra space and making the overall structure of the cup lid more rational. The venting switch is rotatably connected to the inner wall of the central circular groove via a pin, making operation simple and quick, allowing users to vent without complicated procedures.

[0016] The seal is made of silicone, which has good elasticity and sealing properties, ensuring that the cup remains well-sealed during normal use. The mating fit between the mushroom-shaped cap and the seal, along with the spring's elasticity, further enhances the sealing effect and effectively prevents gas leakage.

[0017] The snap-fit ​​cap and the mushroom-shaped nozzle are connected by a snap-fit ​​mechanism, as is the snap-fit ​​seal and the central circular groove, making it easy to disassemble and assemble the components. This design facilitates cleaning and maintenance, extending the lifespan of the cup lid. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a water cup lid with mechanical venting function, such as Figures 1-6As shown, the cup includes a lid body 1, which comprises an upper lid 11 and a lower lid 12. The upper lid 11 has a central circular groove 111 in its center. A venting structure 2 is installed within the central circular groove 111. The venting structure 2 includes a vent switch 24. The side of the vent switch 24 is rotatably connected to the inner wall of the central circular groove 111 via a pin 241. A snap-fit ​​cover 23 is located at the bottom of the vent switch 24, and a small mushroom head 21 is located at the bottom of the snap-fit ​​cover 23. A sealing element 25, made of silicone material, is installed at the bottom of the central circular groove 111. When the outer side of the vent switch 24 is pulled upwards, the small mushroom head 21 is pressed downwards by the lever action, causing the small mushroom head 21 to disengage from the sealing element 25, thereby releasing the internal pressure. By setting the venting structure 2, especially the vent switch 24, whose side is rotatably connected to the inner wall of the central circular groove 111 via a pin 241, a mechanical venting function is achieved. When the outer side of the vent switch 24 is pulled upward, the lever action on the other side pushes the small mushroom head 21 downward, causing the small mushroom head 21 to disengage from the seal 25, thereby quickly and safely releasing the pressure inside the water cup.

[0028] The venting structure 2 is compactly installed in the central circular groove 111 without occupying extra space, making the overall structure of the cup lid body 1 (including the upper cup lid 11 and the lower cup lid 12) more compact and reasonable. The upper cup lid 11 has a central circular groove 111 in the middle, which provides a stable installation position for the venting structure 2.

[0029] The seal 25 is made of silicone, which has good elasticity and sealing properties, ensuring that the cup maintains a good seal during normal use. The tight fit between the mushroom-shaped cap 21 and the seal 25 further enhances the sealing effect and effectively prevents gas leakage. Users can simply pull up the vent switch 24 to release air through leverage; the operation is simple and quick, requiring no complicated steps.

[0030] In this embodiment, the upper lid 11 and the lower lid 12 are rotatably connected on one side by a hinge, and the other side is connected by a snap-fit. This design makes the opening and closing of the lid body 1 more convenient. Users can easily open or close the cup lid with simple operations, improving the ease of use.

[0031] Specifically, the inner wall of the central circular groove 111 is provided with a vertical guide strip, and the outer wall of the snap-fit ​​cover 23 is provided with a guide groove, which slides vertically with the guide strip. This guide design ensures the stability of the snap-fit ​​cover 23 during its up-and-down movement, prevents it from shifting or shaking during operation, and improves the reliability of the venting structure.

[0032] Furthermore, the snap-fit ​​cover 23 has a through hole in its center, and the inner wall of the through hole has a snap-fit ​​inlet 231 and a snap-fit ​​position 232. A snap-fit ​​block 211 is provided at the top of the small mushroom head 21. The top of the small mushroom head 21 passes through the through hole in the center of the snap-fit ​​cover 23, and the snap-fit ​​block 211 rotates 90 degrees after passing through the snap-fit ​​inlet 231 and engages with the snap-fit ​​position 232. This snap-fit ​​connection method makes the connection between the small mushroom head 21 and the snap-fit ​​cover 23 more secure and less prone to falling off, ensuring the integrity of the venting structure.

[0033] Furthermore, the small mushroom head 21 includes a rod and an end. An opening is provided in the center of the bottom of the central circular groove 111. The rod of the small mushroom head 21 slides vertically into the opening, and the end of the small mushroom head 21 fits against the bottom outer side of the opening. This sliding fit design makes the small mushroom head 21 move more smoothly up and down without jamming, improving the smoothness of the degassing operation.

[0034] Furthermore, a spring 22 is provided inside the central circular groove 111. The spring 22 is wound around the outside of the stem of the small mushroom head 21. The bottom of the spring 22 abuts against the inner wall of the central circular groove 111, and the top abuts against the bottom surface of the snap-fit ​​cover 23. The spring 22 provides additional elastic support, allowing the small mushroom head 21 to fit tightly against the seal 25 when not being pressed, thus enhancing the sealing effect. At the same time, after the venting operation, the elasticity of the spring 22 can also help the small mushroom head 21 to quickly reset, improving the response speed of the venting structure.

[0035] Furthermore, a sealing protrusion 251 is integrally formed on the bottom surface of the sealing element 25, and the end of the mushroom head 21 abuts against the sealing protrusion 251. This abutting fit design makes the seal between the sealing element 25 and the mushroom head 21 tighter, effectively preventing gas leakage and improving the heat preservation effect and sealing performance of the water cup.

[0036] Furthermore, a groove is provided on the outer bottom of the central circular groove 111, and an annular retaining strip is provided on the inner wall of the seal 25, which engages with the groove. This engaging design allows the seal 25 to be firmly installed at the bottom of the central circular groove 111, preventing it from falling off or shifting, thus ensuring the stability and durability of the venting structure.

[0037] When using the water cup lid with mechanical venting function, if the pressure inside the water cup increases due to hot water steam or gas released from carbonated beverages, the user needs to vent the air to balance the internal and external pressure.

[0038] Pull the outer side of the vent switch 24 upwards. The side of the vent switch 24 is rotatably connected to the inner wall of the central circular groove 111 via a pin 241, thus allowing for smooth rotation. As the vent switch 24 is pulled upwards, its other side presses down on the locking cover 23 through leverage. After being pressed down, the locking cover 23 moves downwards, simultaneously moving the small mushroom head 21 at its bottom as well.

[0039] The mushroom head 21 includes a stem and an end. The stem slides vertically into the opening at the bottom of the central circular groove 111, and the end is fitted against the bottom outer side of the opening. When the snap-fit ​​cover 23 moves downward, the end of the mushroom head 21 also moves downward, thereby disengaging from the tight fit with the seal 25. The seal 25 is made of silicone material, which has good elasticity and sealing performance. A sealing protrusion 251 is integrally formed on its bottom surface. The end of the mushroom head 21 originally abuts against the sealing protrusion 251 to form a sealed state.

[0040] After the small mushroom head 21 separates from the seal 25, the pressure inside the cup is quickly released through the opening, thereby balancing the internal and external pressures and avoiding noise and spraying caused by the sudden release of air pressure when the cup lid is opened.

[0041] After the venting operation is completed, the user releases the venting switch 24. At this time, the spring 22 inside the central circular groove 111 comes into play. The spring 22 is wrapped around the outside of the stem of the mushroom head 21, with its bottom abutting against the inner wall of the central circular groove 111 and its top abutting against the bottom surface of the snap-fit ​​cover 23. The elasticity of the spring 22 helps the snap-fit ​​cover 23 and the mushroom head 21 to quickly reset, so that the end of the mushroom head 21 tightly fits the sealing protrusion 251 of the seal 25 again, restoring the sealing state.

[0042] The upper lid 11 and the lower lid 12 are connected on one side by a hinge, and on the other side by a snap-fit ​​connection. This design makes opening and closing the lid body 1 more convenient, allowing users to easily open or close the lid with simple operation. A vertical guide strip is provided on the inner wall of the central circular groove 111, and a guide groove is provided on the outer wall of the snap-fit ​​cover 23. The guide groove and guide strip slide vertically together, ensuring the stability of the snap-fit ​​cover 23 during up-and-down movement and preventing it from shifting or shaking during operation. The mushroom-shaped head 21 and the snap-fit ​​cover 23 are snap-fitted together, making the connection between them more secure and less prone to falling off. A slot is provided on the outer bottom of the central circular groove 111, and an annular retaining strip is provided on the inner wall of the sealing element 25. The annular retaining strip engages with the slot, allowing the sealing element 25 to be firmly installed at the bottom of the central circular groove 111, preventing it from falling off or shifting.
