Description

Technical Field

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

[0002] The cup lid is a component used to cover the opening of a cup. It usually has functions such as sealing, heat preservation, and convenient drinking. It is made of food-grade silicone material and is formed by high-temperature vulcanization in a hydraulic press. It is soft, has strong adsorption, can be firmly fixed to the mouth of the cup, has a wide temperature resistance range, is non-toxic and odorless, environmentally friendly and safe, and comes in a variety of colors and can be customized in shape.

[0003] Some cup lids are designed with special drinking spouts or equipped with straws, such as flip-top cup lids, which make it convenient for people to drink directly and control the amount and flow rate of drinking, avoiding choking caused by drinking in large gulps. However, existing flip-top cup lids have certain inconveniences when used.

[0004] First, some flip-top cup lids have obvious shortcomings in design: when the user flips the lid to open the cup, the drinking spout and the straw spout, which should be used separately as needed, will be completely exposed at the same time. This can easily cause hygiene problems when not drinking. In addition, opening both openings at the same time will greatly increase the contact area between the inside of the cup and the outside air. The relatively sealed space originally formed by the lid is broken, and hot air (or cold air) will be quickly lost through the two openings, resulting in a significant reduction in the heat preservation (or cold preservation) effect.

[0005] Therefore, we propose a knob-type cup lid. Utility Model Content

[0006] In response to the existing technology where, when a user flips the lid to open the cup, the drinking spout and straw spout, which should be used separately as needed, are completely exposed at the same time, this can easily lead to hygiene hazards when not in use. Furthermore, opening both openings at the same time greatly increases the contact area between the inside of the cup and the outside air, breaking the relatively sealed space originally formed by the lid. Hot (or cold) air can quickly escape through the two openings, resulting in a significant reduction in the heat preservation (or cold preservation) effect. This utility model provides a knob-type cup lid.

[0007] The technical solution adopted by this utility model is as follows: a knob-type cup lid, including a lid body and a rotating top cover. The lower outer surface of the lid body is provided with a threaded insert. The middle part of the rotating top cover is provided with an opening and a connecting shaft. The opening is located on one side of the connecting shaft. The upper outer surface of the rotating top cover is provided with a rotating arrow. The middle part of the lid body is provided with a straw inlet and a drinking spout. The straw inlet is located on one side of the drinking spout. The upper outer surface of the lid body is provided with an elastic retaining bead and a positioning block. The elastic retaining bead is located on one side of the positioning block. The outer wall of the lid body is provided with a slot. The middle part of the slot is provided with a insert. The inner surface of one end of the rotating top cover is provided with a guide groove.

[0008] Furthermore, the outer wall of the cover is provided with a sliding groove, an embedded slider is provided in the middle of the sliding groove, an insertion hole is provided in the middle of the embedded slider, a cleaning rod is provided in the middle of the insertion hole, an internal rod and a fixing plate are provided in the middle of the cleaning rod, the internal rod passes through the fixing plate, a cleaning brush is fixedly installed on the outer surface of one end of the internal rod, a top plate is provided on the upper outer surface of the internal rod, and a limit spring is provided between the top plate and the fixing plate.

[0009] Furthermore, the rotating top cover is movably connected to the cover body via the connecting shaft, and the cover body and the threaded insert are integrally formed.

[0010] Furthermore, the rotating top cover is integrally formed with the opening and the rotating arrow, and the elastic retaining bead is embedded in the guide groove.

[0011] Furthermore, the card slot is provided in the middle of the card insert, and the card slot is connected to the connecting shaft.

[0012] Furthermore, the built-in rod is welded to the top plate, and the top plate is movably connected to the fixed plate via the limiting spring.

[0013] The beneficial effects of this utility model are:

[0014] In this invention, the rotating top cover is movably connected to the cover body via a connecting shaft. When the rotating top cover rotates, the elastic retaining ball moves along the guide groove, controlling the rotation angle of the rotating top cover. This allows the rotating top cover to drive the opening to rotate. When the opening is at the straw insertion position, the drinking spout is blocked and sealed by the rotating top cover. When the opening is at the drinking spout position, the straw insertion position is blocked and sealed by the rotating top cover. This effectively prevents the straw insertion position and the drinking spout from opening simultaneously, and can also seal and cover the straw insertion position and the drinking spout at the same time. Without affecting the use, it can ensure the hygiene and safety of drinking, and also has a good heat preservation effect.

[0015] In this invention, the embedded slider can drive the cleaning rod to rotate along the slide groove during use. The cleaning rod can be installed on the embedded slider through the insertion hole. When it is necessary to clean the cover, the cleaning rod can be inserted and installed. At the same time, the built-in rod can be pulled down, causing the built-in rod to move the top plate down and compress the limit spring. After the cleaning rod is inserted, the cleaning brush is located inside the threaded insert and the cover. Then the built-in rod can be loosened, and the limit spring will return to its original position, pushing the built-in rod to reset. Then the cleaning brush will fit against the inner wall of the threaded insert and the cover. The embedded slider drives the cleaning brush to rotate, which facilitates cleaning the inner wall of the threaded insert and the cover. After cleaning, the cleaning rod can be disassembled and removed. Attached Figure Description

The middle of the rotating top cover 2 is provided with an opening 4 and a connecting shaft 5, with the opening 4 located on one side of the connecting shaft 5. The upper outer surface of the rotating top cover 2 is provided with a rotating arrow 6. The middle of the cover 1 is provided with a straw inlet 11 and a drinking spout 12, with the straw inlet 11 located on one side of the drinking spout 12. The upper outer surface of the cover 1 is provided with an elastic retaining bead 13 and a positioning block 14, with the elastic retaining bead 13 located on one side of the positioning block 14. The outer wall of the cover 1 is provided with a slot 15, with a insert 16 located in the middle of the slot 15. One end of the inner surface of the rotating top cover 2 is provided with a guide groove 17. When in use, the lid 2 is movably connected to the lid body 1 via the connecting shaft 5. When the rotating top cover 2 rotates, the elastic locking bead 13 moves along the guide groove 17, which can control the rotation angle of the rotating top cover 2. This allows the rotating top cover 2 to drive the opening 4 to rotate. When the opening 4 is at the straw inlet 11, the drinking spout 12 is blocked and sealed by the rotating top cover 2. When the opening 4 is at the drinking spout 12, the straw inlet 11 is blocked and sealed by the rotating top cover 2. This effectively prevents the straw inlet 11 and the drinking spout 12 from opening at the same time. It can also seal and cover the straw inlet 11 and the drinking spout 12 at the same time. Without affecting the use, it can ensure the hygiene and safety of drinking and also has a good heat preservation effect.

[0026] Furthermore, the rotating top cover 2 is movably connected to the cover body 1 via the connecting shaft 5. The cover body 1 and the threaded insert 3 are integrally formed. The rotating top cover 2 is integrally formed with the opening 4 and the rotating arrow 6. The elastic retaining ball 13 is embedded in the guide groove 17. The middle of the insert card 16 is provided with a card slot, which is connected to the connecting shaft 5. When in use, the insert card 16 mainly positions the connecting shaft 5 through the card slot. When it is necessary to disassemble the rotating top cover 2, the insert card 16 can be pulled out first, which allows the rotating top cover 2 to be separated from the cover body 1 for easy cleaning.

[0027] Reference Figure 1 and Figure 4As shown, the outer wall of the cover 1 is provided with a groove 7, and an embedded slider 8 is provided in the middle of the groove 7. An insertion hole 9 is provided in the middle of the embedded slider 8, and a cleaning rod 10 is provided in the middle of the insertion hole 9. An internal rod 18 and a fixing plate 19 are provided in the middle of the cleaning rod 10. The internal rod 18 passes through the fixing plate 19, and a cleaning brush 20 is fixedly installed on the outer surface of one end of the internal rod 18. A top plate 21 is provided on the upper outer surface of the internal rod 18, and a limit spring 22 is provided between the top plate 21 and the fixing plate 19. When in use, the embedded slider 8 can drive the cleaning rod 10 to rotate along the groove 7. The cleaning rod 10 can be installed on the embedded slider 8 through the insertion hole 9. When cleaning the cover 1, the cleaning rod 10 can be inserted and installed. At the same time, the built-in rod 18 can be pulled down, causing the built-in rod 18 to move the top plate 21 down and compress the limiting spring 22. After the cleaning rod 10 is inserted, the cleaning brush 20 is located inside the threaded insert 3 and the cover 1. Then the built-in rod 18 can be loosened, and the limiting spring 22 will return to its original position, pushing the built-in rod 18 to reset. Then the cleaning brush 20 will fit against the inner wall of the threaded insert 3 and the cover 1. The cleaning brush 20 will rotate through the embedded slider 8, which facilitates cleaning the inner wall of the threaded insert 3 and the cover 1. After cleaning, the cleaning rod 10 can be disassembled and removed.

[0028] Furthermore, the built-in rod 18 is welded to the top plate 21, and the top plate 21 is movably connected to the fixed plate 19 through the limiting spring 22. The limiting spring 22 is mainly used to reset the built-in rod 18 during use.

[0029] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0030] During use, the rotating top cover 2 is movably connected to the cover body 1 via the connecting shaft 5. When the rotating top cover 2 rotates, the elastic locking bead 13 moves along the guide groove 17, which can control the rotation angle of the rotating top cover 2. This allows the rotating top cover 2 to drive the opening 4 to rotate. When the opening 4 is at the straw inlet 11 position, the drinking spout 12 is blocked and sealed by the rotating top cover 2. When the opening 4 is at the drinking spout 12 position, the straw inlet 11 is blocked and sealed by the rotating top cover 2. This effectively prevents the straw inlet 11 and the drinking spout 12 from opening simultaneously, and can also simultaneously seal and cover the straw inlet 11 and the drinking spout 12. Without affecting use, it can ensure the hygiene and safety of drinking, and can also provide a good heat preservation effect. The embedded slider 8 can drive the cleaning rod 10 along the slider during use. The groove 7 rotates, and the cleaning rod 10 can be installed on the embedded slider 8 through the insertion hole 9. When it is necessary to clean the cover 1, the cleaning rod 10 can be inserted and installed. At the same time, the built-in rod 18 can be pulled down, so that the built-in rod 18 drives the top plate 21 to move down and compress the limit spring 22. After the cleaning rod 10 is inserted, the cleaning brush 20 is located inside the threaded insert 3 and the cover 1. Then the built-in rod 18 can be loosened. At this time, the limit spring 22 rebounds and resets, which can push the built-in rod 18 to reset. Then the cleaning brush 20 fits against the inner wall of the threaded insert 3 and the cover 1. The embedded slider 8 drives the cleaning brush 20 to rotate, which facilitates the cleaning of the inner wall of the threaded insert 3 and the cover 1. After cleaning, the cleaning rod 10 can be disassembled and removed.
