Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a sliding straw that automatically pops out a cup cover and a water cup. Background Art

[0002] In daily necessities, water cups are used to hold liquids. In order to prevent the liquid in the water cup from flowing out when not drinking, the water cups are often provided with a cup cover to seal the water. When the water is not drinking, the cup cover is used to seal the water, which is convenient for carrying and using the water cup.

[0003] There is also a sliding switch type water cup disclosed in the Chinese utility model patent with authorization announcement number CN219500796U. When drinking water is needed, the sliding switch is pushed to drive the sliding member to slide until the self-locking component automatically locks the sliding switch. During this process, the first guide surface presses against and pushes the second guide surface, driving the first movable member to slide in the movable groove and compress the reset spring. The second movable member slides with the first movable member. After the auxiliary block moves, it no longer presses against the piston member, so that the ejection spring recovers and pushes the piston member to move close to the auxiliary block, and the bottom of the piston member continues to press against the auxiliary block. At the top, the piston column moves with the piston member so that the sealing gasket no longer presses against the water outlet, and the liquid in the cup can flow out of the water outlet through the water outlet groove for the user to drink; when drinking water is no longer needed, the sliding switch is pushed to drive the sliding member to slide until the self-locking assembly automatically locks the sliding switch. At this time, the first guide surface is no longer pressed against the second guide surface, and the reset spring restores and pushes the first movable member to slide close to the movable switch, thereby driving the second movable member and the auxiliary block to move together. The auxiliary block pushes the piston member to move and compresses the ejection spring, and the piston column follows the piston member to move until the sealing gasket presses against the water outlet, and the liquid in the cup no longer flows out. It can be seen that this method is to close and open the water outlet by moving the piston column following the piston member, which requires a more complex internal structure, which is not conducive to production and manufacturing, thus increasing the investment in production and manufacturing costs and cannot be mass-produced.

However, it should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0049] Example 1: See Figure 1 , Figure 2 and Figure 4 , a sliding straw automatic pop-up cup cover comprises a cover body 1, a linkage assembly 2 is arranged inside the cover body 1, a bouncing tube assembly 3 and a closing button assembly 4 are arranged on the linkage assembly 2, and the bouncing tube assembly 3 and the closing button assembly 4 can move up and down under the drive of the linkage assembly 2, and a sliding assembly 5 is arranged on the upper end surface of the cover body 1, and the back and forth sliding of the sliding assembly 5 realizes the bouncing tube assembly 3 to pop out, so that the user can drink water through the bouncing tube assembly 3, and when the closing button assembly 4 is pressed to start, the bouncing tube assembly 3 is driven to move downward by the linkage assembly 2, and then the sliding assembly 5 covers the bouncing tube assembly 3 when it returns to its original position, preventing the bouncing tube assembly 3 from popping up, so that it is in a closed state, and when drinking is needed, it only needs to slide the sliding assembly 5, so that the bouncing tube assembly 3 and the closing button assembly 4 can simultaneously pass through the cover body 1 and move upward under the guidance of the linkage assembly 2.

[0050] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the cover body 1 includes a main body 11 and a cover 12 arranged on the upper end surface of the main body 11, and the main body 11 is provided with a accommodating cavity 13 for installing the linkage assembly 2, and the linkage assembly 2 can move up and down in the accommodating cavity 13, and the main body 11 is provided with a first through hole and a second through hole for the corresponding bouncing tube assembly 3 and the closing button assembly 4 to slide back and forth up and down, and the cover 12 is provided with a third through hole for the closing button assembly 4 to slide back and forth up and down, and the cover 12 is provided with a mounting hole for installing the sliding assembly 5, and the bouncing tube assembly 3 can bounce out from the mounting hole. During use, the sliding assembly 5 slides to one side, so that the mounting hole will leave space for the bouncing tube assembly 3, and the bouncing tube assembly 3 will pop out. At this time, the closing button assembly 4 will also move upward, so that the user can drink water through the bouncing tube assembly 3. When the closing button assembly 4 is pressed downward, the closing button assembly 4 will move the bouncing tube assembly 3 downward together through the linkage assembly 2, so that the sliding assembly 5 will return to its position to block the bouncing tube assembly 3 from moving upward, thereby realizing the closed state.

[0051] Further, if Figure 3 As shown, a sealing ring 14 is provided on the main body 11, which is helpful to improve the sealing performance during the later use.

[0052] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, the linkage assembly 2 includes a linkage member 21 arranged inside the cover body 1, and the linkage member 21 is connected to the inside of the cover body 1 through a shaft body 22. The linkage member 21 rotates back and forth up and down inside the cover body 1 with the shaft body 22 as a fulcrum. A bouncing tube assembly 3 and a closing button assembly 4 are arranged on the linkage member 21. The shaft body 22 is located on one end of the linkage member 21, the bouncing tube assembly 3 is located on the other end of the linkage member 21, and the closing button assembly 4 is located on the linkage member 21 between the shaft body 22 and the bouncing tube assembly 3. This arrangement is beneficial for the linkage member 21 to drive the bouncing tube assembly 3 and the closing button assembly 4 to move upward and downward at the same time. To further illustrate, the ratio of the distance between the bouncing tube assembly 3 and the closing button assembly 4 and the distance between the closing button assembly 4 and the shaft body 22 is 3:1. This arrangement is conducive to achieving that the length of the bouncing tube assembly 3 exposed on the upper end surface of the cover body 1 is greater than the length of the closing button assembly 4 exposed on the upper end surface of the cover body 1. This is not only conducive to the user to drink water through the bouncing tube assembly 3 exposed on the upper end surface of the cover body 1, but also when closing, it only needs to press down the closing button assembly 4 exposed on the upper end surface of the cover body 1, and pressing the closing button assembly 4 exposed on the upper end surface of the cover body 1 is easier. In the present embodiment, the length of the bouncing tube assembly 3 exposed on the upper end surface of the cover body 1 is 25 mm, and the length of the closing button assembly 4 exposed on the upper end surface of the cover body 1 is 10 mm. This is not only conducive to the user to drink water through the bouncing tube assembly 3 exposed on the upper end surface of the cover body 1, but also when closing, it only needs to press down the closing button assembly 4 exposed on the upper end surface of the cover body 1, which is easier to press and more conducive to the user's operation.

[0053] Among them, Figure 4 As shown, in this embodiment, the linkage member 21 includes a linkage plate 211, a connecting rod 212 is provided at one end of the linkage plate 211, a fixing rod 213 is provided on the connecting rod 212, the fixing rod 213 and the linkage plate 211 are connected together through a connecting shaft 214, and a bouncing tube assembly 3 is connected to the other end of the linkage plate 211, and a closing button assembly 4 is connected to the connecting shaft 214, and the shaft body 22 passes through the connecting rod 212. This arrangement is reasonable and easy to implement.

[0054] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9As shown, the bouncing tube assembly 3 includes a limiting hole 31 provided on the linkage assembly 2 and a straw 32 provided in the cover body 1 and capable of sliding up and down. The straw 32 is provided with a first return spring 33, and the straw 32 is provided with a limiting column 34 for being installed in the limiting hole 31. The first return spring 33 is conducive to realizing the upward movement of the straw 32, and is also conducive to realizing that the straw 32 can only move up and down. The limiting hole 31 is a strip hole, and the strip hole is particularly a ball-shaped hole. The limiting column 34 moves back and forth in the strip hole, which is conducive to realizing the up and down movement of the straw 32.

[0055] like Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the closing button assembly 4 includes a placement hole 41 provided on the linkage assembly 2 and a return button 42 provided in the cover body 1 and capable of sliding up and down. The return button 42 is provided with a second return spring 43, which is conducive to the return and reset of the return button 42. The return button 42 is provided with a mounting post 44 for mounting in the placement hole 41, which is conducive to enabling the return button 42 to move up and down in the cover body 1. The placement hole 41 is a bar-shaped hole, and the bar-shaped hole is particularly a ball-shaped hole. The mounting post 44 moves back and forth in the bar-shaped hole, which is conducive to realizing the up and down movement of the return button 42.

[0056] Embodiment 5: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 4 , Figure 5 , Figure 7 , Fig.10 and Fig.11As shown, the sliding assembly 5 includes a slider 51 which is arranged on the upper end surface of the cover body 1 and can slide back and forth. The slider 51 is located above the bouncing tube assembly 3. This is beneficial for the slider 51 to cover the bouncing tube assembly 3 when the bouncing tube assembly 3 is not in use, which is beneficial for preventing the bouncing tube assembly 3 from bouncing out. The slider 51 is provided with a sliding shaft 52, and a slide groove 53 which is arranged on the cover body 1 for the sliding shaft 52 to slide, and a third reset spring 54 is arranged between the sliding shaft 52 and the cover body 1. This is beneficial for the slider 51 to automatically reset after the external force is removed. When in use, the slider 51 can be pushed with force, and the sliding shaft 52 slides in the slide groove 53. At this time, the third reset spring 54 will be stretched and have the elasticity to restore to its original state. In this way, the bouncing tube assembly 3 will lose the obstruction of the slider 51, and the bouncing tube assembly 3 can move upward. The bouncing tube assembly 3 will cause one end of the linkage assembly 2 to move upward, which will cause the closing button assembly 4 to move upward together with the linkage assembly 2. At this time, the bouncing tube assembly 3 can be opened for drinking water. When the closing button assembly 4 is pressed downward, the downward movement of the closing button assembly 4 will cause one end of the linkage assembly 2 to move downward, and the linkage assembly 2 will drive the bouncing tube assembly 3 to move downward as well. Then, the slider 51 covers the bouncing tube assembly 3 when the third reset spring 54 is reset. In this way, the slider 51 will block the bouncing tube assembly 3 from moving upward, and the bouncing tube assembly 3 can be in a closed state.

[0057] like Figure 4 , Figure 5 , Figure 7 , Fig.10 and Fig.11 As shown, two sliding shafts 52 are used, and the two sliding shafts 52 pass through the slider 51, and corresponding sliding grooves 53 are arranged on the cover body 1 on both sides of the slider 51, which is more conducive to the slider 51 to slide back and forth more stably, one end of the third return spring 54 is fixed on the cover body 1, and the other end of the third return spring 54 is fixed on the end of the sliding shaft 52 away from the end of the third return spring 54, which is more conducive to the slider 51 to return to its original state after sliding.

[0058] like Fig.10 As shown, the slide groove 53 includes a horizontal groove 531 and an inclined groove 532 (arc groove), and the horizontal groove 531 is connected to the inclined groove 532, which is conducive to the sliding shaft 52 sliding back and forth, making the sliding more stable and avoiding the slider 51 from flipping during the sliding process.

[0059] like Figure 4 and Figure 7 As shown, the third return spring 54 is located at an upper position on one side of the bouncing tube assembly 3 , which is helpful to prevent the linkage assembly 2 from moving up and down and touching the third return spring 54 .

[0060] like Figure 4 and Fig.11 As shown, a pad 55 is provided on the lower surface of the slider 51 located above the bouncing tube assembly 3, which is conducive to better sealing the upper port of the bouncing tube assembly 3 and also improves hygiene. It is further explained that the pad 55 is made of silicone pad, which is widely available and easy to implement.

[0061] Embodiment 6: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4 or Embodiment 5, such as Fig.12 As shown, the utility model also provides a water cup, including a cup body 10, and the above-mentioned sliding straw automatic pop-up cup cover 20 is arranged at the opening of the cup body 10. Further explanation, the opening of the cup body 10 and the sliding straw automatic pop-up cup cover 20 are threadedly connected, that is, the inner side wall of the opening of the cup body 10 is provided with an internal thread, and the outer side wall of the sliding straw automatic pop-up cup cover 20 is provided with an external thread, and the external thread and the internal thread cooperate with each other to realize the detachable connection between the cup body 10 and the sliding straw automatic pop-up cup cover 20, which is convenient for installation and disassembly.

[0062] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts and rivets in the prior art, which will not be described in detail here.

[0063] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model.
