[0023] In the above-mentioned three-drinking water cup, a hollow enclosure is fixedly provided on the top of the lower cover, and a plurality of cantilevers are provided between the inner wall of the enclosure and the central hole. The area enclosed by two adjacent cantilevers is the above-mentioned direct drinking port.

[0024] In the above three-drinking cup, a pressing piece is fixedly provided on the inner top surface of the upper cover. When the upper cover is closed on the middle cover, the pressing piece presses the hose downward to seal the suction nozzle.

[0025] In the above-mentioned three-drinking water cup, the base and the hose are integrally formed.

[0026] In the above-mentioned three-drinking water cup, the suction nozzle is made of thermochromic silicone material.

[0027] In the above-mentioned three-drinking water cup, when the cup cover is turned upside down, the base can be seen through the direct drinking port on the lower cover.

[0028] Through the thermochromic silicone material, the nozzle can change the corresponding color according to the water temperature. After opening the upper cover, the water temperature can be judged by observing the color of the hose; after opening the middle cover, the water temperature can be judged by observing the color of the base on the middle cover; when the cup lid is turned upside down, the water temperature can be judged by seeing the base through the direct drinking port on the lower cover. The nozzle can be seen in three different ways of drinking water, so the water temperature can be judged by the color of the nozzle, which serves as a reminder.

[0029] In the above three-drinking water cup, the upper cover is hingedly arranged on the middle cover, and a buckle structure is provided between the upper cover and the middle cover for locking the position of the upper cover and the middle cover after they are covered.

[0030] In the above-mentioned three-drinking water cup, the buckle structure includes a button movably arranged on the middle cover and a lock buckle fixed on the upper cover. The middle cover is fixed with an upper slide seat integrally formed with the middle cover. The button is horizontally slidably arranged in the inner cavity of the upper slide seat. An upper clamping block is fixed on the button. An upper plug hole connected to its inner cavity is opened on the top of the upper slide seat. The upper cover is pressed to insert the lock buckle into the upper plug hole. A reset spring is also provided in the upper slide seat to push the button outward so that the upper clamping block is inserted into the lock buckle to form a lock. Pressing the button separates the upper clamping block from the lock buckle to release the lock.

[0031] In the above-mentioned three-drinking water cup, a stop-recognition protrusion is fixedly provided on the button, and a guide slope is provided on the side of the stop-recognition protrusion facing the center of the middle cover. A avoidance hole corresponding to the position of the stop-recognition protrusion is also provided on the button. When the button is installed in the upper slide, the avoidance hole provides an avoidance space for the stop-recognition protrusion to be squeezed and deformed. When the stop-recognition protrusion enters the upper insertion hole, the reset spring pushes the button, and the stop-recognition protrusion can be blocked by the inner wall of the upper insertion hole to prevent the button from falling out of the upper slide.

[0032] In the above three-drinking cup, the middle cover is hingedly arranged on the lower cover, and a second buckle structure is provided between the middle cover and the lower cover for locking the position of the middle cover and the lower cover after they are covered.

[0033] In the above-mentioned three-drinking cup, the second buckle structure includes a second button movably arranged on the lower cover and a lock hook fixedly arranged on the middle cover. The lower cover is fixedly provided with a lower sliding seat integrally formed with the lower cover. The second button is horizontally slidably arranged in the inner cavity of the lower sliding seat. A lower card block is fixedly provided on the second button. A lower plug hole connected to its inner cavity is opened on the top of the lower seat. The middle cover is pressed to insert the lock hook into the lower plug hole. A second reset spring is also provided in the lower seat to push the second button outward so that the lower card block is inserted into the lock hook to form a lock. Press the second button to separate the lower card block from the lock hook to release the lock.

[0034] In the above-mentioned three-drinking cup, a second anti-recognition protrusion is fixedly provided on the button 2, and a anti-recognition groove communicating with its inner cavity is provided on the top of the lower slide. A guide slope is provided on the side of the second anti-recognition protrusion facing the center of the lower cover. A second avoidance hole corresponding to the position of the second anti-recognition protrusion is also provided on the button 2. When the button 2 is installed in the lower slide, the second anti-recognition protrusion is simultaneously installed in the anti-recognition groove. The second avoidance hole provides an avoidance space for the second anti-recognition protrusion to be squeezed and deformed. When the second anti-recognition protrusion enters the anti-recognition groove, when the reset spring 2 pushes the button 2, the second anti-recognition protrusion can be blocked by the inner wall of the anti-recognition groove to prevent the button 2 from falling out of the lower slide.

[0035] In the above-mentioned three-drinking water cup, there are two anti-retraction slots, which are respectively arranged on the left and right sides of the lower insertion hole.

[0036] In the above three-drinking water cup, a buckle is rotatably provided on the lower cover, and the buckle is flipped upward to be fastened to the upper cover.

[0037] In the aforementioned three-drink cup, after the buckle is flipped upward and fastened, the top surface of the buckle is flush with the top surface of the cup lid. When the cup lid is opened and turned upside down, due to the small top surface area of ​​the upper lid itself, a slight shake may cause the cup lid to tip over. By flipping the buckle upside down and fastening it, the top surface of the buckle can also work together with the top surface of the upper lid to support the cup lid when it is turned upside down, thereby increasing the overall support surface area of ​​the cup lid.

[0038] In the aforementioned three-drink water cup, when the buckle is flipped upward and fastened, the outer end surfaces of buttons 1 and 2 are flush with the side of the cylindrical cup body. Conventional cylindrical water cups tend to roll when placed horizontally. By supporting the water cup with the outer end surfaces of buttons 1 and 2 working together with the cup body, the cup body is prevented from rolling. Beneficial effects

[0039] Compared with the existing technology, it has the following beneficial effects:

[0040] 1. The water cup of the present invention has three drinking methods: open the upper cover and drink water through the spout, which is the first drinking method; open the middle cover and drink water through the drinking spout, which is the second drinking method; unscrew the entire cup cover, leave the straw in the cup body, turn the entire cup cover upside down, pour the water in the cup into the inner cavity of the lower cover, and use it as a drinking cup, which is the third drinking method;

[0041] 2. The water filter hole on the connector plays a filtering role. When drinking directly or pouring water from the cup into the cup lid, the connector plays a filtering role.

[0042] 3. The nozzle is made of thermochromic silicone material and changes color according to the water temperature. After opening the upper cover, the water temperature can be judged by observing the color of the hose; after opening the middle cover, the water temperature can be judged by observing the color of the base on the middle cover; when the cup lid is turned upside down, the base can be seen through the direct drinking port on the lower cover to judge the water temperature. The nozzle can be seen in all three different ways of drinking water, so the water temperature can be judged by the color of the nozzle, which serves as a reminder.

[0043] 4. By flipping the buckle upside down and fastening it, the top surface of the buckle can work together with the top surface of the upper cover to support the cup lid when the cup lid is inverted, thereby increasing the overall support surface area of ​​the cup lid; when the water cup is placed horizontally, the outer end surfaces of buttons 1 and 2 work together with the cup body to support the water cup, playing the role of preventing the cup body from rolling;

[0044] 5. When adding water to an ordinary double-drink cup, you need to remove the entire cup lid, which is inconvenient. The present invention has multiple direct drinking ports, which make the overall opening area of ​​the direct drinking ports larger. After opening the middle cover, a large diameter direct drinking port is exposed, allowing you to add water directly. The enclosure on the lower cover not only facilitates direct drinking of water, but also prevents water from overflowing when adding.

[0045] 6. The mounting hole and the center hole are concentrically arranged, which is actually the concentric arrangement of the suction nozzle center and the center of the direct drinking port. Different from the front-to-back staggered design of the two holes in similar products, the present invention is more stable. At the same time, the suction nozzle is positioned further forward during opening and use, which is convenient for use.

[0046] 7. The upper and lower buttons are secured using no traditional metal latches. Instead, they are secured by means of retaining bumps that snap into place once the buttons are pressed in. The second button and the lower cover are fixed on either side, reducing the thickness of the second button and the lower seat, minimizing the depth of the button slot and minimizing the height of the button structure in the overall design. This results in a more harmonious and aesthetically pleasing overall design, and provides more stable fixation on both sides. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0061] As shown in Figures 1 to 6, a three-drinking cup according to the present invention includes a cup body 1 and a cup cover. The cup cover includes an upper cover 2, a middle cover 3 and a lower cover 4 arranged in sequence from top to bottom. The middle cover 3 is provided with a suction nozzle 5. The upper cover 2 is movably connected to the middle cover 3 for blocking the suction nozzle 5 or opening the suction nozzle 5; a straight drinking port 6 is opened on the top of the lower cover 4, and the middle cover 3 is movably connected to the lower cover 4 for blocking or opening the straight drinking port 6. A holding device and a straw 17 are provided in the cup body 1. The straw 1 The cup body 1 is held in a position where it can dock with the nozzle 5 by a retaining device. When the lower cover 4 is closed over the mouth of the cup body 1 and the middle cover 3 is closed over the lower cover 4, the nozzle 5 docks and communicates with the straw 17. When the lower cover 4 is separated from the cup body 1, the straw 17 is separated from the nozzle 5 and can remain in the cup body 1. The bottom of the cup cover has a receiving cavity. When the upper cover 2 is closed over the middle cover 3 and the middle cover 3 is closed over the lower cover 4, the cup cover is turned upside down and the receiving cavity is used as a water storage cavity. The straw 17 remains stationary when the lower cover 4 is closed or separated from the cup body 1.

[0062] A pressing piece 28 is fixed on the inner top surface of the upper cover 2. When the upper cover 2 is closed on the middle cover 3, the pressing piece 28 presses the hose 20 downward to block the suction nozzle 5. When the upper cover 2 is opened, the hose 20 returns to its original state, and water is drunk through the suction nozzle 5. This is the first way of drinking water (as shown in Figure 2); open the middle cover 3 and drink water through the direct drinking port 6. This is the second way of drinking water (as shown in Figure 3); unscrew the entire cup cover, leave the straw 17 in the cup body 1, turn the entire cup cover upside down, pour the water in the cup into the inner cavity of the lower cover 4, and use it as a drinking cup. This is the third way of drinking water.

[0063] As shown in FIG4 , the retaining device is a connector 7. A connecting tube 8 integrally formed with the connector 7 is fixed on the connector 7. The connecting tube 8 connects the inner cavity and the outer side of the cup body 1. The lower end of the connecting tube 8 docks with the straw 17 in the cup body 1, and the upper end of the connecting tube 8 can dock with the mouthpiece 5. The connector 7 includes a sheet-like body 9 and a circle of connecting walls 10 arranged on the outer periphery of the body 9. A circle of ribs 11 is fixed on the bottom of the connecting wall 10. A retaining ring 12 is fixed on the inner wall of the cup body 1. An avoidance groove 13 is provided at the bottom of the connecting wall 10. After the connector 7 is inserted into the cup body 1, when the rib 11 on the connecting wall 10 passes over the retaining ring 12, the avoidance groove 13 provides an avoidance space for the rib 11 to be squeezed and deformed. After the rib 11 passes over the retaining ring 12, the retaining ring 12 abuts against the top surface of the rib 11 to prevent the connector 7 from falling out of the cup body 1. The connecting piece 7 and the straw 17 of the present invention can be designed as separate parts or as an integrated part.

[0064] The upper edge of the connecting wall 10 is folded outward to form a connecting edge 15. A sealing ring 16 is fitted over this connecting edge 15. The lower end of the sealing ring 16 presses against the rim of the cup body 1, and the lower cover 4 presses against the upper end of the sealing ring 16. Installing the connector 7 also secures the position of the sealing ring 16. The cup lid of this invention does not have a sealing member installed. The sealing ring 16 is installed at the rim of the cup body 1. The lid is connected to the cup body 1 via threads and also provides a seal.

[0065] The body 9 is provided with a plurality of water filter holes 14. The water filter holes 14 are arc-shaped and are concentrically arranged around the center of the connecting tube 8. The water filter holes 14 serve as a filter. Whether drinking directly or pouring water from the cup into the cup lid for use, the connecting member 7 performs a filtering function.

[0066] As shown in FIG5 , the middle cover 3 has a mounting hole, into which the suction nozzle 5 is fixedly embedded. The top of the lower cover 4 has a central hole 18, through which the suction nozzle 5 and the straw 17 connect to form a water outlet. There are at least two direct drinking ports 6, each of which is arranged around the central hole 18. The direct drinking ports 6 are arc-shaped and concentrically arranged around the central hole 18.

[0067] When adding water to an ordinary double-drinking cup, the entire cup lid needs to be removed, which is inconvenient to use. The present invention has a plurality of direct drinking ports 6, so that the overall opening area of ​​the direct drinking port 6 is larger. After opening the middle cover 3, the large-diameter direct drinking port 6 is exposed, and water can be added directly. The mounting hole and the center hole 18 are concentrically arranged, which is actually the concentric arrangement of the center of the suction nozzle 5 and the center of the direct drinking port 6. Different from the front-to-back offset design of the two holes of similar products, the present invention is more stable. At the same time, the position of the suction nozzle 5 is more forward during opening and use, which is convenient for use.

[0068] As shown in Figure 6, the suction nozzle 5 includes a base 19 and a hose 20 arranged on the base 19 and integrally formed with the base 19. The base 19 includes a cylindrical base 21, a mounting column 22 fixed to the top of the base 21, and a positioning column 23 fixed to the bottom of the body. The mounting column 22 is fixedly embedded in the mounting hole of the middle cover 3. When the middle cover 3 is closed on the lower cover 4, the base 21 is pressed against the top of each direct drinking port 6 to seal each direct drinking port 6. The positioning column 23 is embedded in the center hole 18 of the lower cover 4.

[0069] The mounting post 22 has a mounting slot 24 defined around its periphery. The suction nozzle 5 is inserted upward through the mounting hole of the middle cover 3 until the post 22 passes over the hole, whereupon the suction nozzle 5 is secured within the hole. The outer diameter of the mounting slot 24 matches the inner diameter of the hole. The positioning post 23 has a tapered guide surface 25 defined around its periphery. When the middle cover 3 is closed onto the lower cover 4, the suction nozzle 5 is forced into the center hole 18 of the lower cover 4 via this tapered guide surface 25. The bottom surface of the positioning post 23 has a concave curved surface 26, while the top surface of the connecting tube 8 has a convex curved surface 27. When the middle cover 3 is closed onto the lower cover 4, the positioning post 23 passes through the center hole 18 and presses against the connecting tube 8. The concave curved surface 26 on the positioning post 23 and the convex curved surface 27 on the connecting tube 8 abut against each other, forming a sealed connection.

[0070] A hollow enclosure 29 is fixed to the top of the lower cover 4. A plurality of cantilevers 30 are provided between the inner wall of the enclosure 29 and the central hole 18. The area enclosed by two adjacent cantilevers 30 is the above-mentioned direct drinking port 6. After opening the middle cover 3, water from the direct drinking port 6 flows into the enclosure 29, making it convenient for the user to drink and not easy to overflow when adding water.

[0071] The nozzle 5 is made of thermochromic silicone material. When the cup lid is inverted, the base 19 can be seen through the direct drinking port 6 on the lower cover 4. The nozzle 5 changes color according to the water temperature. After opening the upper cover 2, the water temperature can be judged by observing the color of the hose 20; after opening the middle cover 3, the water temperature can be judged by observing the color of the base 19 on the middle cover 3. When the cup lid is inverted, the base 19 can be seen through the direct drinking port 6 on the lower cover 4 to judge the water temperature. The nozzle 5 can be seen in all three different ways of drinking water, so the water temperature can be judged by the color of the nozzle 5, serving as a reminder.

[0072] As shown in Figures 7 and 8, the upper cover 2 is hingedly mounted on the middle cover 3. A buckle structure is provided between the upper cover 2 and the middle cover 3 for locking the upper cover 2 and the middle cover 3 in their closed position. The buckle structure includes a button 31 movably mounted on the middle cover 3 and a lock catch 32 fixed to the upper cover 2. The middle cover 3 is fixed with an upper slide 33 integrally formed with the middle cover 3. The button 31 slides horizontally within the inner cavity of the upper slide 33. An upper clamping block 34 is fixed to the button 31. An upper insertion hole 35 communicating with the inner cavity of the upper slide 33 is formed at the top. Pressing the upper cover 2 causes the lock catch 32 to be inserted into the upper insertion hole 35. A return spring is also provided within the upper slide 33 for pushing the button 31 outward, causing the upper clamping block 34 to be inserted into the lock catch 32 to form a lock. Pressing the button 31 separates the upper clamping block 34 from the lock catch 32 to release the lock.

[0073] As shown in Figure 11, a stop-recognition protrusion 36 is fixedly provided on the button 31, and a guiding slope is provided on the side of the stop-recognition protrusion 36 facing the center of the middle cover 3. A avoidance hole 1 corresponding to the position of the stop-recognition protrusion 36 is also provided on the button 31. When the button 31 is installed in the upper slide 33, the avoidance hole 1 provides an avoidance space for the stop-recognition protrusion 36 to be squeezed and deformed. When the stop-recognition protrusion 36 enters the upper insertion hole 35, when the reset spring 1 pushes the button 31, the stop-recognition protrusion 36 can be blocked by the inner wall of the upper insertion hole 35 to prevent the button 31 from falling out of the upper slide 33.

[0074] As shown in Figures 9 and 10, the middle cover 3 is hingedly mounted on the lower cover 4. A second buckle structure is provided between the middle cover 3 and the lower cover 4 for locking the middle cover 3 and the lower cover 4 in their closed position. The second buckle structure includes a second button 37 movably mounted on the lower cover 4 and a lock hook 38 fixedly mounted on the middle cover 3. The lower cover 4 is fixedly provided with a lower slide 39 integrally formed with the lower cover 4. The second button 37 is horizontally slidably mounted in the inner cavity of the lower slide 39. A lower clamping block 40 is fixedly mounted on the second button 37. A lower insertion hole 41 communicating with the inner cavity of the lower slide 39 is formed at the top of the lower slide 39. Pressing the middle cover 3 causes the lock hook 38 to be inserted into the lower insertion hole 41. A second return spring is further provided in the lower slide 39 for pushing the second button 37 outward, so that the lower clamping block 40 is inserted into the lock hook 38 to lock the lower cover. Pressing the second button 37 causes the lower clamping block 40 to separate from the lock hook 38 to release the lock.

[0075] As shown in FIG12 , the second button 37 is fixed with a second anti-recoil protrusion 42. The top of the lower slide 39 is provided with an anti-recoil slot 43 communicating with the inner cavity thereof. The side of the second anti-recoil protrusion 42 facing the center of the lower cover 4 is provided with a guide slope.
