Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a press-type pop-up lid and a thermos cup. Background Technology

[0002] Insulated water bottles, as a common household item, are usually equipped with lids to provide dust protection and insulation. In traditional insulated water bottle designs, the lid needs to be fully unscrewed before pouring water. However, this design has certain limitations. In actual use, users often need both hands to open the lid smoothly. In special situations, such as carrying heavy objects with one hand, during exercise, or in other scenarios where two hands are inconvenient, it is difficult for users to open the lid of a traditional insulated water bottle with only one hand, causing inconvenience.

[0003] To address this issue, some thermos cups with press-to-open lids have emerged on the market. These thermos cups were designed to allow users to easily drink water with one hand. However, existing press-to-open thermos cups often have structural design shortcomings. For example, Chinese utility model patent CN210672929U, entitled "A Detachable and Washable Lid and a Thermospheric Cup Using the Lid," includes an outer lid, an inner lid that covers the spout of the outer lid, and a switch structure for moving the inner lid. The lid controls the movement of the inner lid through the switch structure to open and close the spout. However, the switch structure of this lid is relatively complex, including multiple components such as a mounting component, a pressing slider, a return spring, and a spline, with complex relationships between these components.

[0004] The above-mentioned switch structure requires the processing and assembly of multiple components, and the processing and assembly accuracy requirements of these components are high, which further increases the production difficulty and cost. At the same time, due to the large number of components, daily maintenance may be inconvenient. Utility Model Content

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0028] Example 1

[0029] This embodiment mainly describes the push-button pop-up cup lid, as follows:

[0030] like Figures 1 to 8 As shown, the push-button pop-up cup lid includes an outer cover 1 and a water-sealing assembly 2. The lower side of the outer cover 1 extends into the opening of the cup body 8 and works in conjunction with the cup body 8. The outer cover 1 has a water outlet 11 that communicates with the cup body 8 for water to flow out of the cup body 8. The outer cover 1 also has a fixing bracket 3 located below the water outlet channel, which supports and fixes the water-sealing assembly 2. The water-sealing assembly 2 is used to close or open the water outlet 11. The water-sealing assembly 2 includes a water-sealing cap 21, a spring 22, and a limiting cylinder 23. The water-sealing cap 21 is adapted to the water outlet 11 and is located below the water outlet 11. Under normal conditions, the water-sealing cap 21 is tightly pressed against the water outlet 11 by the elastic force of the spring 22 to achieve a seal. The bottom of the water-sealing cap 21 has a downwardly extending connecting shaft 24, and the connecting shaft 24 has outward protrusions 241 on both sides. The limiting cylinder 23 is fixed on the fixing frame 3. Its inner wall has limiting grooves 4 on both sides that mate with the protruding part 241. A guide rail 5 is provided within the limiting groove 4 to guide the protruding part 241 to or out of the limiting groove 4. A spring 22 is sleeved on the connecting shaft 24, with one end abutting against the bottom of the sealing cap 21 and the other end abutting against the upper end of the guide rail 5. When the sealing cap 21 is pressed, it slides down and disengages from the outlet 11. The limiting groove 4 and the protruding part 241 engage to limit the sealing cap 21, opening the outlet 11. Water in the cup body 8 can then pass through the fixing frame 3 and pour out from the outlet 11. When the sealing cap 21 is pressed again, the protruding part 241 disengages from the limiting groove 4, and under the action of the spring 22, the sealing cap 21 slides up to seal the outlet 11. In this solution, by setting up components such as a fixed frame 3 and a water sealing assembly 2 (including a water sealing cover 21, a spring 22, and a limiting cylinder 23), compared with the complex switch structure in the prior art (such as mounting parts, pressing sliders, reset springs, splines, etc.), this utility model reduces the number of components, reduces the processing and assembly difficulty in the production process, and at the same time, due to the reduction in the number of components, the cooperation relationship between the components is also simpler, reducing the component maintenance cost.

[0031] like Figures 4 to 8As shown, the fixing frame 3 includes a connecting ring 31 and connecting arms 32, with at least two connecting arms 32, preferably three. A limiting cylinder 23 is located inside the connecting ring 31, and the connecting arms 32 are located between the limiting cylinder 23 and the connecting ring 31, preferably at the center of the connecting ring 31. One end of each connecting arm 32 is fixedly connected to the connecting ring 31, and the other end is fixedly connected to the limiting cylinder 23. The connecting arms 32 are evenly distributed around the circumference of the connecting ring 31. The connecting ring 31 is fixedly connected to the lower edge of the outer cover 1 or threadedly connected. The fixed connection is generally welded or snap-fitted, making the connection between the fixing frame 3 and the outer cover 1 more secure; the threaded connection facilitates the installation and disassembly of the fixing frame 3, making it convenient for users to clean and maintain the cup lid. The limiting cylinder 23 provides stable support for the water-sealing assembly 2, ensuring that the water-sealing cover 21 can accurately slide along the limiting groove 4 during pressing, improving the performance and reliability of the cup lid.

[0032] like Figure 6 As shown, the limiting cylinder 23 includes two concentric inner sleeves 231 and outer sleeves 232 with the same bottom surface, forming an annular guide channel 2321 between the inner sleeves 231 and the outer sleeves 232. Guide rails 5 are provided on the inner walls on both sides of the inner sleeves 231, and the connecting shaft 24 slides within the inner sleeves 231. The bottom of the sealing cap 21 is provided with a guide cylinder 211, which covers the connecting shaft 24 and extends into the guide channel 2321. The guide cylinder 211 is adapted to the guide channel 2321 and can slide along the guide channel 2321. This structural design allows the sealing cap 21 to slide smoothly up and down along the guide channel 2321 during pressing, preventing the sealing cap 21 from shaking or jamming during movement and improving the smoothness of the cup cap's use. Meanwhile, the cooperative structure of the guide channel 2321 and the guide cylinder 211 provides precise guidance for the movement of the water sealing cover 21, ensuring that the protrusion 241 can accurately enter or leave the limiting groove 4, thus realizing the reliable opening and closing of the water outlet 11.

[0033] Specifically, the outer wall of the inner sleeve 231 is provided with guide protrusions 2311 along the vertical direction, such as... Figure 7 As shown, the inner wall of the guide cylinder 211 is provided with a guide groove 212 that mates with the guide protrusion 2311. The engagement of the guide protrusion 2311 and the guide groove 212 further restricts the horizontal movement of the sealing cap 21, allowing it to slide only up and down along the guide groove 212. This further improves the stability and accuracy of the sealing cap 21's movement, while eliminating wear caused by lateral swaying of the guide cylinder 211 and extending its service life. This design not only enhances the structural reliability of the cup cap but also improves the user experience, making the pressing operation smoother and more precise.

[0034] like Figure 6 As shown, the inner sleeve 231 is a racetrack-shaped cylinder, such as... Figure 7As shown, the connecting shaft 24 is a racetrack-shaped column adapted to the racetrack-shaped cylinder. The connecting shaft 24 has an operating channel 242 extending along its length. The top surface of the connecting shaft 24 has a recessed non-circular mounting groove 243, and the bottom of the non-circular mounting groove 243 has a connecting hole 244 communicating with the operating channel 242. The bottom surface of the water-sealing cover 21 has a protrusion 213 adapted to the non-circular mounting groove 243, and the protrusion 213 has a threaded hole corresponding to the connecting hole 244. The connecting shaft 24 is fixed to the water-sealing cover 21 by screws passing through the connecting hole 244 and engaging with the threaded hole. This structural design makes the connection between the connecting shaft 24 and the water-sealing cover 21 more secure. Simultaneously, the cooperation of the non-circular mounting groove 243 and the protrusion 213 restricts the rotational freedom of the connecting shaft 24, ensuring that the connecting shaft 24 will not rotate due to external forces during use, thereby ensuring that the outer protrusion 241 is always aligned with the guide rail 5. In addition, the design of the operating channel 242 facilitates the installation and removal of the connecting shaft 24, making it convenient for users to maintain and clean the cup lid.

[0035] Specifically, the two parallel walls of the connecting shaft 24 are symmetrically provided with transverse slots 245. Connecting rods 6 are installed within the two transverse slots 245, and the two ends of the connecting rods 6 extend out of the two transverse slots 245 to form the aforementioned protrusions 241. A U-shaped seat 7 is provided at the lower end of the connecting shaft 24. Vertical slots 71 are provided on the two arms of the U-shaped seat 7, and the U-shaped seat 7 is fitted onto the two protrusions 241 through the two vertical slots 71. This structural design makes the connection between the protrusions 241 and the connecting shaft 24 more stable. At the same time, the cooperation between the U-shaped seat 7 and the vertical slots 71 enables the detachable connection of the protrusions 241, facilitating the maintenance and replacement of the water-sealing assembly 2.

[0036] like Figure 6As shown, the inner sleeve 231 has vertically extending mounting blocks 2312 on the inner walls of its two parallel walls. A limiting groove 4 is formed on each of the two mounting blocks 2312, and two guide rails 5 are symmetrically arranged on the two mounting blocks 2312. Each guide rail 5 includes a downwardly inclined opening 51 and a left V-shaped guide wall 52 and a right V-shaped guide wall 53 connected to the left and right sides of the opening 51, respectively. The openings of the two V-shaped guide walls face each other. The limiting groove 4 is located between the two V-shaped guide walls and has an inverted V-shaped structure. The orthographic projection of the ends of the two inclined surfaces of the opening 51 falls on the top surface of the right inclined arm of the limiting groove 4. There are gaps between the right inclined arm of the limiting groove 4 and the right V-shaped guide wall 53, and between the left inclined arm of the limiting groove 4 and the left V-shaped guide wall 52, allowing the outwardly protruding part 241 to slide through. A guide block 54 is provided below the limiting groove 4. The left side of the guide block 54 has a first guide surface 541 that cooperates with the left V-shaped guide wall 52 to guide the protruding part 241 out of the limiting groove 4, and the right side has a second guide surface 542 that cooperates with the right V-shaped guide wall 53 to guide the protruding part 241 into the limiting groove 4. When the sealing cap 21 is pressed for the first time, the connecting shaft 24 drives the protruding part 241 to slide from the opening 51 into the guide rail 5, and slides into the right V-shaped guide wall 53 under the guidance of the right inclined arm of the limiting groove 4, and slides from the end of the V-shaped guide wall to the second guide surface 542. When the connecting shaft 24 slides to the U-shaped seat 7 against the bottom of the inner sleeve 231, the connecting shaft 24 can no longer slide down, and the sealing cap 21 can no longer slide down. When the pressing of the sealing cap 21 is stopped, under the action of the spring 22, the protruding part 241 slides up the second guide surface 542 to the limiting groove 4, thereby fixing the sealing cap 21. During this process, the sealing cap 21 moves down with the protrusion 241 to open the outlet 11. When the sealing cap 21 is pressed again, the connecting shaft 24 slides down, causing the protrusion 241 to move down to the first guide surface 541 and continue to slide along the first guide surface 541. When the connecting shaft 24 slides to the U-shaped seat 7 against the bottom of the inner sleeve 231, the connecting shaft 24 can no longer slide down, and the sealing cap 21 can no longer slide down. At this time, the sealing cap 21 is stopped from being pressed. Under the action of the spring 22, the protrusion 241 slides up along the first guide surface 541 to the left V-shaped guide wall 52, and slides up along the gap between the V-shaped guide wall and the left inclined arm of the limiting groove 4 to the opening 51. During this process, the sealing cap 21 moves up with the protrusion 241 and abuts against the outlet 11 to close the outlet 11.

[0037] This structural design allows the protruding part 241 to smoothly enter or exit the limiting groove 4 during pressing, achieving reliable positioning and unlocking of the water-sealing cover 21. Simultaneously, the design of the V-shaped guide wall and guide block 54 provides a smooth guiding path for the movement of the protruding part 241, reducing friction between the protruding part 241 and the limiting groove 4, and extending the service life of the water-sealing assembly 2. The cooperation between the guide rail 5, the transverse slot 245 on the connecting shaft 24, the vertical slot 71 on both arms of the U-shaped seat 7, and the connecting rod 6 allows the connecting rod 6 to slightly deflect according to the shape of the guide rail 5, ensuring that the protruding part 241 can smoothly slide into the limiting groove 4.

[0038] Specifically, the bottom of the limiting cylinder 23 is provided with a drain hole 233. The design of the drain hole 233 prevents water from being stored in the limiting cylinder 23 for a long time, which can breed bacteria and leave stains. In order to improve the drainage effect, the bottom of both the outer sleeve 232 and the inner sleeve 231 are provided with drain holes 233.

[0039] Specifically, the bottom edge of the sealing cap 21 has an outward-facing annular step 214. The annular step 214 abuts against the bottom wall of the outer cap 1 at the outlet 11. An annular groove 215 is provided between the annular step 214 and the top surface of the sealing cap 21, and a first sealing ring 216 is fitted inside the annular groove 215. The function of the first sealing ring 216 is to further enhance the sealing performance between the sealing cap 21 and the outer cap 1, ensuring that liquid will not overflow from the gap when the sealing cap 21 blocks the outlet 11. This matching structure of the annular step 214 and the sealing ring not only improves the sealing performance of the cup cap, but also makes the contact between the sealing cap 21 and the outer cap 1 tighter, reducing liquid residue inside the cup cap and facilitating cleaning and maintenance.

[0040] Example 2

[0041] This embodiment mainly describes the push-button pop-up cup lid, as follows:

[0042] like Figure 3 and Figure 8As shown, a thermos cup includes a cup body 8, a storage cup 10, and a push-button pop-up lid. The push-button pop-up lid fits onto the mouth of the cup body 8. A connecting cover 9 is integrally formed at the bottom of the cup body 8. The inner wall of the connecting cover 9 has internal threads, and the side wall of the mouth of the storage cup 10 has external threads that match the internal threads. The storage cup 10 is threadedly connected to the connecting cover 9. The storage cup 10 can hold items such as tea and pills, which can be accessed by rotating the bottom of the cup body 8, allowing for separate storage of beverages and other items. The cup body 8 uses a double-layer vacuum stainless steel structure, and a silicone sealing ring 12 is provided at the mouth of the cup, forming a third seal with the threaded connection of the lid. The storage cup 10 can also be snapped onto the connecting cover 9. Specifically, the inner wall of the connecting cover 9 has an annular sealing groove 13, and the mouth of the storage cup 10 has an elastic protruding ring that mates with the annular sealing groove 13. The storage cup 10 is snapped onto the connecting cover 9 by the engagement of the annular protruding ring and the annular sealing groove 13.
