[0021] like Figure 2-11 As shown, the cup lid includes a cup lid body 1, a straw 5, a switch 3 and a transmission mechanism. The cup lid body 1 is provided with a straw receiving cavity 12 with a side opening. The upper part of the straw 5 is disposed in the straw receiving cavity 12, and the dust cover 2 is disposed on the opening side of the straw receiving cavity 12. In the initial state, the upper part of the straw 5 is located inside the straw receiving cavity 12, and the dust cover 2 is located on the opening side of the straw receiving cavity 12, which is in a closed state. When drinking water, the switch 3 is pushed horizontally. The switch 3 drives the transmission mechanism to rotate the dust cover 2 away from the opening side of the straw receiving cavity 12 around the cup lid. At the same time, the transmission mechanism drives the straw 5 to rotate, and the water outlet end of the straw 5 rotates out of the cup lid from the opening side of the straw receiving cavity 12. After drinking water, the switch is pushed in the opposite direction. The upper part of the straw rotates back to the inside of the straw receiving cavity 12, and the dust cover 2 rotates to the opening side of the straw receiving cavity 12. The straw receiving cavity 12 is closed again, and the drinking outlet is sealed inside the cup lid, which can prevent dust and bacteria and other small particles from entering the cup.
[0022] like Figure 4-5 As shown in Figures 9-11, the dust cover 2 has teeth 21 on its inner side, and a straw gear 61 is fixed on the straw 5. The transmission mechanism includes a fixed shaft 41, a rack assembly, and a gear assembly sleeved on the fixed shaft 41. The fixed shaft 41 is fixed inside the cup lid. The switch 3 is connected to the rack assembly, the rack assembly is connected to the gear assembly, and the gear assembly is connected to the teeth 21 and the straw gear 61.
[0023] The rack includes a first rack 25 and a second rack 64. The gear set includes a first gear 24, a second gear 23, a third gear 63, and a fourth gear 62. The cup lid body 1 is provided with a rack slide rail 16. The second rack 16 is slidably mounted on the rack slide rail 16. The first rack 25 is located at the upper end of the second rack 64. The fourth gear 62 is fixedly connected to the lower end of the third gear 63. The third gear 63 meshes with the second rack 64, and the fourth gear 62 meshes with the straw gear 61. The second gear 23 is fixedly connected to the upper end of the first gear 24. The first gear 24 meshes with the first rack 25. The second gear 23 is horizontally meshed with a transmission gear 22. The transmission gear 22 meshes with teeth 21. The cup lid body 1 is provided with a protrusion 15 for mounting the transmission gear 22. The transmission gear 22 is sleeved on the protrusion 15. Optionally, the second gear 23 meshes with teeth 21, and the transmission gear 22 and protrusion 15 are not provided.
[0024] Pushing the switch causes the first rack 25 to drive the first gear 24 to rotate. The second gear 23 rotates coaxially with the first gear 24. The second gear 23 indirectly drives the dust cover 2 to rotate through the transmission gear 22, so that the dust cover 2 rotates on the opening side of the straw receiving cavity 12. At the same time, the switch pushes the second rack to drive the third gear to rotate. The fourth gear 62 rotates coaxially with the third gear 63. The fourth gear 62 drives the straw gear to drive the straw to rotate.
[0025] like Figure 2-3 As shown, the cup lid also includes a cup lid top cover 7, which is installed on the upper end of the cup lid body 1 by screws.
[0026] like Figure 6 As shown, the cup lid body 1 is provided with a dust cover storage groove 13 located at one end of the opening side of the straw receiving cavity 12.
[0027] like Figure 10-11As shown, the switch 3 is fixedly connected to the first rack 25, and there is a certain distance between the switch 3 and the second gear 64. The first rack 25 has a groove 26, and the upper end of the second rack 64 has a protrusion 65 located in the groove 26. When the switch 3 is pushed forward, since the switch 3 is fixedly connected to the first rack 25 and there is a certain distance between the switch 3 and the second gear 23, the switch 3 first pushes the first rack 25, causing the protrusion 65 to move from the end near the inside of the cup lid to the end away from the inside of the cup lid within the groove 26. At the same time, the switch 3 indirectly drives the dust cover 2 to slide a portion from the side of the straw receiving cavity 12 into the dust cover storage groove 13. After the opening on the side of the straw receiving cavity 12 is opened, the switch 3 connects with the second gear 23. Touching the switch 3, the first gear 24 and the second gear 23 are pushed simultaneously until the dust cover 2 slides completely into the dust cover storage groove 13, the straw rotates completely out, and the switch 3 is pressed to the bottom. During the process of pushing the switch 3 backward, since the switch 3 is not directly connected to the second rack 64, the switch 3 first drives the first rack 25 to pull back and drive the dust cover 2 to slide out from the inside of the dust cover storage groove 13. The protrusion 65 moves from the end away from the inside of the cup lid to the end closer to the inside of the cup lid in the groove 26. If the switch 3 is pushed backward, the first rack 25 continues to pull back, and at the same time, the groove 26 drives the protrusion 65 to drive the second rack 64 to pull back until the switch 3 is fully restored, the straw is completely retracted into the cup lid and is not connected from top to bottom, and the dust cover 2 completely seals the opening of the straw receiving cavity 12.
[0028] Optionally, the switch 3 is fixedly connected to the first rack 25 and the second rack 64. The first rack 25 has a toothed front section but no toothed rear section, while the second rack 64 has a toothed rear section but no toothed front section. When the switch 3 is pushed forward, the first rack 25 and the second rack 64 move forward simultaneously. Since the second rack 64 does not have a toothed front section, it cannot drive the third gear. Therefore, the first rack 25 first drives the dust cover to retract into the dust cover storage slot. When the second rack 64 and the toothed front section mesh with the third gear, the second rack drives the third gear to rotate the straw out of the side of the cup lid. When the switch is pushed backward, the first rack (25) and the second rack 64 move backward simultaneously. Since the first rack 25 does not have a toothed rear section, the first rack (25) moves backward. Since the convex teeth cannot drive the first gear, the second rack first drives the straw back into the cup lid, and the first rack then drives the dust cover to rotate to the opening side of the straw receiving cavity 12. More specifically, the convex teeth of the first rack 25 and the second rack 64 can be completely staggered. That is, when the switch 3 is pushed forward, the dust cover is fully opened, and the straw rotates out of the cup lid. When the switch is pushed backward, the straw rotates completely back into the straw receiving cavity 12, and the dust cover rotates to the opening side of the straw receiving cavity 12. The convex teeth of the first rack 25 and the second rack 64 can also overlap. That is, when the dust cover is partially opened, the straw opens along with the dust cover, and when closed, the straw closes along with the dust cover. The length of the overlap can be set as needed, as long as the dust cover and the straw do not collide. The overlapping arrangement of the convex teeth of the first rack 25 and the second rack 64 can reduce the overall length of the racks.
[0029] So Figure 9-10 As shown, the straw includes a rotating part and a fixed part. The rotating part includes a drinking part 51 and a water inlet part 52. The drinking part 51 is connected to the water inlet part 52 and is fixed to the upper end of the water inlet part 52. The straw receiving cavity 12 is provided with a vertically arranged through hole 14. The cup lid is also provided with a water-separating plate 4. The water-separating plate 4 is fixed to the lower end of the cup lid body. The water inlet part 52 is located in the through hole 14 and passes through the water-separating plate 4. The straw gear is fixedly sleeved on the outside of the water inlet part 52. When the straw rotates, the water inlet part 52 rotates on its own axis, and the drinking part 51 rotates around the water inlet part 52, thereby causing the drinking part 51 to rotate out of the outside of the cup body 8 for easy drinking.
[0030] So Figure 9-10As shown, the fixing part is fixed to the lower end of the water-separating plate 4. The fixing part includes a vertical water inlet pipe 56 and a horizontal water passage trough 55. The vertical water inlet pipe 56 and the horizontal water passage trough 55 are connected. A circular slot is provided on the horizontal water passage trough 55. The water inlet end of the water inlet part 52 is inserted into the circular slot. A water passage hole 54 is provided on one side of the circular slot. A water inlet hole 53 is provided on one side of the water inlet end of the water inlet part 52. When the drinking spout is located inside the cup lid, the water passage hole 54 and the water inlet hole 53 are not connected. When the drinking spout is rotated out of the cup lid, the water passage hole 54 and the water inlet hole 53 are connected. The lower end of the vertical water inlet pipe 56 can extend to the water storage space inside the cup.
[0031] The water passage 54 and the water inlet 53 are at the same horizontal level. When the straw is inside the cup lid, the water passage 54 and the water inlet 53 have a certain angle, and the straw is not connected vertically, so as to prevent the water in the cup from spilling when the cup is inverted or shaken. The angle between the water passage 54 and the water inlet 53 with the axis of the water inlet 52 as the intersection point is equal to the angle at which the drinking part 51 is completely rotated out of the cup lid. When the straw is rotated out of the cup lid, the angle between the water passage 54 and the water inlet 53 is zero, the straw is connected vertically, and water can be drunk directly.
[0032] like Figure 6-8 As shown, the cup lid also includes a buckle 31. The cup lid body 1 is provided with a switch mounting part 11 and a buckle mounting part 19. The buckle mounting part 19 is located at the lower end of the switch mounting part 11. The inner side of the switch mounting part 11 is provided with a spring mounting groove 17. The end of the first spring 36 away from the switch 3 is fixed in the spring mounting groove 17. The switch 3 can slide in the switch mounting part 11. The switch mounting part 11 is provided with a rack and pinion slide rail 16. The second rack 64 is slidably installed in the rack and pinion slide rail 16. The switch 3 can push the second rack 64 when it slides in the switch mounting part 11. The lower end of the buckle mounting part 19 is provided with a spring mounting hole 18. The end of the second spring 37 away from the buckle 31 is fixed to the side of the spring mounting hole 18. The end of the second spring 37 near the buckle 31 is fixedly connected to a spring connector 35. The spring connector 35 can slide in the spring mounting hole 18. The space of the buckle mounting part 19 gradually expands from the inside to the outside of the cup lid. One end of the buckle mounting part 19 near the inside of the cup lid has a rotating shaft mounting groove 192 for mounting the rotating shaft 32. When the other end of the buckle 31 is pressed, the buckle 31 rotates downwards around the rotating shaft 32. A vertical plate 34 is also provided at the lower end of the buckle 31, and a vertical plate receiving cavity 191 is provided at the lower end of the buckle mounting part 19. After the buckle 31 is pressed down, the vertical plate 34 abuts against the vertical plate receiving cavity 191, thus enhancing structural stability.
[0033] During the process of pushing the switch 3, the switch 3 contacts the inclined side of the positioning protrusion 33 and presses down the buckle 31. The first spring 36 and the second spring 37 are compressed. The switch 3 is pressed to the bottom. The switch 3 is disengaged from the inclined side of the positioning protrusion 33. The restoring force of the second spring 37 pushes the buckle 31 back to its original state, and the pushing force of the switch 3 is removed. The vertical side of the positioning protrusion 33 holds the switch 3, so that the switch 3 is always in the state of being pressed to the bottom. The straw is also in the state of being outside the cup lid and connected from top to bottom for easy drinking. After drinking water, press down on the buckle 31, compress the second spring 37, and the switch 3 disengages from the vertical side of the positioning protrusion 33. The restoring force of the first spring 36 restores the switch 3 to its original position, and the restoring force of the second spring 37 restores the switch 3 to its original position, and the buckle 31 also returns to its original position. like Figure 1 As shown, a water cup includes the aforementioned cup lid and cup body 8, wherein the cup lid and cup body 8 are connected by a threaded connection.
[0034] All of the above processes require only one hand to pick up the cup and press switch 3 once to drink immediately, and pressing the latch 31 again will restore it to its original state, achieving dustproof and water spill prevention. This invention is simple to operate, ingeniously structured, and integrates multiple functions, making it highly suitable for widespread use.
[0035] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
