(22) As shown in FIGS. 1-10, according to the embodiments of the present disclosure, a cup lid with a straw is provided, including a cup lid body 1 and a slider 2 slidably connected with the cup lid body 1. The cup lid body 1 is configured to cover a cup mouth of a cup body. The cup lid body 1 is provided with a first channel 12 from a first side 110 facing the cup mouth to a second side 120 distal from the cup mouth, and the first channel 12 communicates with the cup body. The first channel 12 has an upper channel opening 121 at the second side 120 distal from the cup mouth. By disposing the first channel 12 which extends into the cup body, the fluid in the cup body can smoothly flow into the internal structure of the cup lid with a straw. The upper channel opening 121 serves as a liquid outlet of the cup lid body 1, ensuring the stability and continuity for a liquid flow path. Meanwhile, this structure is helpful to improve the overall sealing performance and prevent liquid leakage when the cup is not in use. The slider 2 functions as a core control component, enabling switching between opening and closing of the first channel for liquid through sliding. The slider 2 includes a second channel 23 and its lower channel opening 231, forming a key channel for the liquid to flow from the cup lid body 1 to a drinking straw 3. The structural design of the slider 2 ensures smooth liquid flow and excellent guidance.

(23) In some embodiments, as shown in FIGS. 4-10, a water outlet sealing block 4 is embedded in a first receiving groove 24 in the bottom of the slider 2, which not only saves the space, but also makes the overall structure more compact. Meanwhile, the water outlet sealing block 4 is prevented from shifting or falling off during sliding, improving the operational stability. The water outlet sealing block 4 is disposed at one side close to the upper channel opening 121 of the first channel 12, ensuring accurate engagement and disengagement with the upper channel opening 121 of the first channel 12 during the sliding of the slider 2, thereby improving the reliability of the switching action.

(24) The water outlet sealing block 4 slides synchronously with the slider 2, and has a sealing portion 41 and a water outlet hole portion 42, allowing the user to control the opening and closing of the channel for liquid through a simple sliding action.

(25) In some embodiments, as shown in FIG. 6, one side, close to the upper channel opening 121, of each of the sealing portion 41 and the water outlet hole portion 42 is respectively provided with a first annular protrusion 41a and a second annular protrusion 42b that protrude outward. The first annular protrusion 41a and the second annular protrusion 42b are configured to enhance the sealing effect, and reduce the frictional force between the water outlet sealing block 4 and a sinking groove 11 by reducing the contact area between the sealing portion 41 and the water outlet hole portion 42, and the bottom of the sinking groove 11. While moving, the first annular protrusion 41a and the second annular protrusion 42b remain closely fitted to the bottom of the sinking groove 11, ensuring tight contact between the water outlet sealing block 4 and the bottom of the sinking groove 11, thereby preventing water leakage.

(26) The water outlet hole portion 42 is aligned with the lower channel opening 231 of the second channel 23, enabling both to be accurately abutted no matter the slider 2 is at a first position 11a or a second position 11b. When the slider 2 is at the first position 11a, a continuous fluid flow path is formed, ensuring a smooth and unobstructed drinking process. The sealing portion 41 is made of an elastic material, such as food-grade silica gel, which can tightly fit with the channel opening 121 after the slider 2 slides in place, effectively preventing the leakage of a fluid such as liquid or air, thereby improving the safety and portability for the product.

(27) When the slider 2 slides to the first position 11a, the upper channel opening 121 of the first channel 12, the water outlet hole portion 42 and the lower channel opening 231 of the second channel 23 are aligned and are in communication. In this case, a complete liquid flow path is formed among the three components, allowing the user to drink normally through the drinking straw. The cup lid is intuitive and convenient to operate, and suitable for one-handed use, especially for scenarios such as driving and exercising.

(28) When the slider 2 slides to the second position 11b, the sealing portion 41 of the water outlet sealing block 4 covers the upper channel opening 121 of the first channel 12 for sealing, blocking the communication between the upper channel opening 121 of the first channel 12 and the lower channel opening 231 of the second channel 23, and preventing the fluid such as liquid or air from flowing out through the upper channel opening 121. In this state, all channels for liquid and air are cut off, ensuring no liquid leakage even if the cup is tilted or inverted, thereby greatly improving the sealing performance and usage safety for the product, and making the cup lid suitable for daily carrying and use in different environments.

(29) In some embodiments, as shown in FIGS. 4-6 and FIGS. 9-10, the cup lid body 1 is further provided with an air vent 13 configured to be in communication with the interior of the cup body. The cup lid with a straw further includes an air outlet sealing block 5 embedded in a second receiving groove 25 in the bottom of the slider 2, and close to one side of the air vent 13. The air vent 13 is configured to communicate the air pressures inside and outside the cup body during drinking, preventing poor water flow due to negative pressure. When the slider 2 is at the first position 11a, the air vent remains open, ensuring normal drinking. When the slider slides to the second position 11b, the air outlet sealing block 5 slides to block off the air vent 13, preventing liquid leakage through the air vent 13.

(30) The air outlet sealing block 5 moves synchronously with the water outlet sealing block 4. When the slider 2 slides to the closing position in the second position 11b, both the water outlet channel and the air vent channel are sealed, forming a complete sealing system that effectively prevents liquid leakage from either channel. The sealed air vent 13 and upper channel opening 121 can prevent external pollutants such as dust and bacteria from entering the interior of the cup body, ensuring the cleanliness and drinking safety for the beverage.

(31) In some embodiments, as shown in FIGS. 1-10, the cup lid body 1 further includes a drinking straw 3 detachably connected with the second channel 23 in a inserting manner and synchronously moving with the slider 2. Meanwhile, the user can quickly mount or remove the drinking straw 3 as needed, improving the flexibility and convenience for use. The drinking straw 3 can be replaced independently, allowing the user to choose the drinking straw 3 with different lengths, materials or shapes according to actual requirements, such as a bendy straw for children, and a bite-type straw for sports, thereby improving the applicability for the product. Additionally, the drinking straw 3 can be taken out independently and thoroughly cleaned, effectively preventing dirt accumulation and bacterial growth, thereby improving the sanitary performance for the product. The drinking straw 3 is in the shape of a truncated cone with a narrow top and a wide bottom, which is helpful to guide liquid to the drinking straw smoothly, reduce the flow resistance, and improve the smoothness and comfort while drinking. As shown in FIG. 4, a first end 3a of the drinking straw 3 is a sipping end, and a second end 3b of the drinking straw 3 is inserted into an outer tube wall 232 of the second channel 23 with an interference fit, by which a tight connection between both is ensured, avoiding problems such as liquid leakage or poor drinking due to looseness. A continuous fluid flow path is formed between the drinking straw 3 and the second channel 23 when both are connected.

(32) In some embodiments, a sinking groove 11 is recessed in a direction from an upper surface of the cup lid body 1 towards the interior of the cup body, and both the upper channel opening 121 of the first channel 12 and the air vent 13 are disposed on the bottom surface of the sinking groove 11. The design of the sinking groove 11 concentrates the upper channel opening 121 of the first channel 12 and the air vent 13 at the bottom of the sinking groove 11, making the overall structure more compact, effectively utilizing the internal space of the cup lid, and avoiding external interference. The slider 2 is configured to selectively slide in the sinking groove 11, and the sinking groove 11 provides excellent limiting and guiding functions, ensuring that the slider 2 moves stably in the sinking groove 11 during movement, without shifting or wobbling. Meanwhile, the sinking groove 11 forms a partially enclosed space, facilitating a tighter fit between the slider 2 and the water outlet sealing block 4 and the air outlet sealing block 5, reducing the risk of liquid leakage, and further improving the overall sealing effect.

(33) In some embodiments, a first inner side wall 1a of the sinking groove 11 is provided with a first slideway 111, and a second inner side wall 1b of the sinking groove 11 is provided with a second slideway 112. A first outer wall 2a of the slider 2 is provided with a first clamping block 21, and a second outer wall 2b of the slider 2 is provided with a second clamping block 22. The slider 2 is slidably connected with the cup lid body 1 through sliding fit between the first clamping block 21 and the first slideway 111 and sliding fit between the second clamping block 22 and the second slideway 112. In this case, the slider 2 have excellent guidance and limiting function during moving, ensuring an accurate sliding path and a steady movement. The slider 2 is slidably connected with the cup lid body 1 through sliding fit between the first clamping block 21 and the first slideway 111 and sliding fit between the second clamping block 22 and the second slideway 112. The dual-side slideways in cooperation with the clamping blocks effectively prevent the slider 2 from deviating, jamming or tilting during sliding, improving the operating feel of the user, and making the opening and closing actions smoother and more reliable. The first clamping block 21 and the first slideway 111, and the second clamping block 22 and the second slideway 112 are engaged in an embedded sliding manner, allowing the slider 2 to be mounted and positioned without complicated fasteners, thereby improving the assembly efficiency, and facilitating subsequent disassembly and cleanliness or replacement of parts. The slider 2 can only slide along a predefined path using a slideway limiting structure, preventing accident opening due to an external force, and further improving the safety and portability for the product.

(34) In some embodiments, the cup lid body 1 has a lower port extension portion 10 for connecting to the cup mouth. The lower port extension portion 10 has an external thread 101 connected with an internal thread of the cup mouth. The cup lid body 1 is in cooperation with the cup mouth of the cup body through the lower port extension portion 10 disposed at its lower end, and the cup lid is securely fastened to the cup body by screwing the external thread 101 with the internal thread of the cup mouth, preventing accidental falling off during use. Compared with a snap-fit or inserting connection structure, the threaded connection provides a higher connection tightness, which is helpful to enhance the sealing performance between the cup lid and the cup body, preventing liquid leakage during carrying or use.

(35) In some embodiments, as shown in FIG. 6, a lower end face of the slider 2 is integrally designed as a groove structure. An upper bottom wall of the groove is disposed with one or more annular protrusions, dividing the groove into form a first receiving groove 24 and a second receiving groove 25. Through the above structural design of the annular protrusions, the material usage for the slider 2 can be reduced, thereby reducing the manufacturing cost. Moreover, the contact area between the lower end face of the slider 2 and the bottom of the sinking groove 11 is reduced, reducing the frictional force, which facilitates smoother sliding of the slider 2 on the cup lid body 1. More importantly, the structural design of the grooves and the annular protrusions can further improve the elastic deformation capability of the side walls where the clamping blocks are located on the slider 2, allowing the slider 2 to more easily deform and restore during mounting or removal, thereby improving the assembly convenience and the user experience.

(36) In the present disclosure, the sliding of the slider 2 enables the water outlet sealing block 4 and the air outlet sealing block 5 to synchronously move, controlling the opening and closing of the upper channel opening 121 and the air vent 13, thereby achieving a control over the connection and disconnection of the channel for liquid and the channel for air. In conjunction with multiple innovations such as the design of detachable drinking straw, the structure of sinking groove, and the dual-slideway guiding mechanism, a solution for the cup lid with a straw, which has a compact structure, is easy to operate and convenient to clean and maintain, and has high sealing performance, is realized.

(37) The cup lid body 1 is preferably made of high-strength food-grade polypropylene or tritan copolyester materials, and the drinking straw 3 is made of food-grade silica gel, ensuring that the product is safe and non-toxic during a long-term use, and meets high standard requirements of modern consumers for health and hygiene.

(38) The above are only some of the embodiments of the present disclosure, and are not used to limit the present disclosure. For those skilled in the art, various modifications and variations can be made to the present disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present disclosure shall fall within the protection scope of the present disclosure.
