[0025] It should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "set up," "connected," "linked," and "hollow" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] See Figure 1 This embodiment of a double-drinking cup includes at least a cup body 1, a direct-drinking lid 2, and a spout lid 3. The direct-drinking lid 2 is mounted on the cup body 1 and has a direct-drinking spout 21 and a straw interface 22. The direct-drinking spout 21 is connected to the inner cavity of the cup body 1, and the straw interface 22 is connected to a straw 23 located within the inner cavity of the cup body 1. The spout lid 3 is mounted on the direct-drinking lid 2 and has a spout 31. The spout 31 has a first working position and a second working position. When the spout 31 is in the first working position, it is connected to the straw interface 22; when the spout 31 is in the second working position, it is not connected to the straw interface 22.

[0027] When a user needs to drink directly, they can open the spout cover 3 to expose the drinking port 21 of the drinking cover 2, and drink water using the drinking port 21. When a user needs a straw 23, they can drive the spout 31 to switch from the second working position to the first working position, connecting the spout 31 with the straw 23, allowing the user to drink water directly using the straw 23.

[0028] Specifically, the drinking lid 2 can be threaded onto the cup body 1, or it can be rotatably connected to the cup body 1, opening or closing via a snap-fit ​​structure, or other existing connection methods, which are not limited here. In this embodiment, the drinking lid 2 is threaded onto the top of the cup body 1. Similarly, the spout lid 3 can be threaded onto the drinking lid 2, or it can be rotatably connected to the drinking lid 2, opening or closing via a snap-fit ​​structure, or other existing connection methods, which are not limited here. In this embodiment, the spout lid 3 is rotatably connected to the drinking lid 2, opening or closing via a snap-fit ​​structure. Furthermore, the spout 31 can be rotatably connected to the spout lid 3, or it can be slidably connected to the spout lid 3, allowing the spout 31 to switch between a first working position and a second working position. In this embodiment, the spout 31 is rotatably connected to the spout lid 3.

[0029] In one embodiment, see Figure 2-4 The spout cover 3 has a pressure relief channel 32, which has a first vent 321 and a second vent 322. The first vent 321 and the second vent 322 are connected, and the first vent 321 is connected to the drinking spout 21. Through this pressure relief channel 32, the inner cavity of the cup body 1 can be directly connected to the outside, and the air pressure inside the cup body 1 is consistent with the outside air pressure, making it convenient for users to drink water smoothly using the spout 31. At the same time, the direct use of the drinking spout 21 simplifies the structure, reduces the possibility of leakage, and improves the overall sealing of the double drinking cup.

[0030] Since the drinking spout 21 is directly opposite the first vent 321, liquid in the cup body 1 may directly enter the pressure relief channel 32 from the drinking spout 21. Therefore, to prevent this from happening, the first vent 321 can be one or more vent micropores, and the pore diameter of the vent micropores is 0.4-1mm. In this embodiment, the first vent 321 includes multiple vent micropores, the pore diameter of the vent micropores is 0.6mm, and the multiple vent micropores are evenly distributed.

[0031] When the suction nozzle 31 is not needed, to prevent objects from entering the pressure relief channel 32, the suction nozzle 31 in the second working position can block the second vent 322 of the pressure relief channel 32. Specifically, the suction nozzle 31 has a plug 311, which can be inserted into the second vent 322 to close it. When the suction nozzle 31 is in the first working position, the suction nozzle 31 is connected to the straw interface 22, and the plug 311 is disengaged from the second vent 322 to open the pressure relief channel 32. When the suction nozzle 31 is in the second working position, the suction nozzle 31 is not connected to the straw interface 22, and the plug 311 is inserted into the second vent 322 to close the pressure relief channel 32.

[0032] In one embodiment, see Figure 2-4 The nozzle cover 3 has a liquid suction channel 33, which has a first liquid inlet 331 and a second liquid inlet 332. The first liquid inlet 331 and the second liquid inlet 332 are connected. The first liquid inlet 331 is connected to the straw interface 22, and the second liquid inlet 332 can be connected to the nozzle 31. When the nozzle 31 is in the first working position, the liquid inlet 312 of the nozzle 31 is opposite to the second liquid inlet 332 and is connected to the second liquid inlet 332, allowing the user to drink water using the nozzle 31. When the nozzle 31 is in the second working position, the liquid inlet 312 of the nozzle 31 is not opposite to the second liquid inlet 332 and is not connected to the second liquid inlet 332.

[0033] In one embodiment, see Figure 2-4 The top of the spout cover 3 is provided with a handle 34, and the spout 31 is movably mounted on the handle 34. In this embodiment, the spout 31 is rotatably mounted on the handle 34. Since the spout 31 is located on the handle 34, the distance between the spout 31 and the drinking cover 2 is relatively large, resulting in a long pressure relief channel 32 and a long liquid suction channel 33. Therefore, in order to facilitate cleaning of the pressure relief channel 32 and the liquid suction channel 33, the double drinking cup also includes a connecting component 4. The connecting component 4 is detachably installed inside the spout cover 3 by means of the disassembly component 5. The connecting component 4 has a pressure relief channel 32 and a liquid suction channel 33. The pressure relief channel 32 is connected to the drinking spout 21, and the liquid suction channel 33 is located between the straw interface 22 and the spout 31 so that the straw interface 22 is connected to the spout 31.

[0034] Specifically, see Figure 6 and Figure 7 The disassembly assembly 5 includes a fastener 51, a latch 52, and a reset member 53. The fastener 51 is disposed in one of the connecting assembly 4 and the nozzle cover 3. The latch 52 is movably disposed in the other of the connecting assembly 4 and the nozzle cover 3. The latch 52 can engage with the fastener 51 to fix the connecting assembly 4 inside the nozzle cover 3. The reset member 53 is used to drive the latch 52 to engage with the fastener 51. In this embodiment, the fastener 51 is disposed on the nozzle cover 3 and has a locking hole 511. The latch 52 is slidably connected to the connecting assembly 4 and can be inserted into the locking hole 511 to fix the connecting assembly 4 inside the nozzle cover 3. The reset member 53 is disposed between the latch 52 and the connecting assembly 4.

[0035] Specifically, see Figure 6 and Figure 7The connecting component 4 includes a base 41 and a cover plate 42. A first cavity 411 is provided at the top of the base 41, a locking member 52 is slidably disposed in the first cavity 411, and a resetting member 53 is disposed in the first cavity 411. A second cavity 412 is provided at the top of the base 41, allowing gas flow. A third cavity 413 is provided at the top of the base 41, allowing liquid flow. A first gas inlet 414 and a first liquid inlet 415 are provided at the bottom of the base 41. The first gas inlet 414 communicates with the second cavity 412 and is connected to the drinking spout 21. The first liquid inlet 415 communicates with the third cavity 413 and is connected to the straw inlet 22. The cover plate 42 is detachably or fixedly installed on the top of the base 41. Preferably, the cover plate 42 is fixedly installed on the base 41 by welding. Cover plate 42 seals the first cavity 411, the second cavity 412, and the third cavity 413, making them relatively independent and not interconnected. Cover plate 42 is provided with a second gas interface 421 and a second liquid interface 422. The second gas interface 421 communicates with the second cavity 412, and the second liquid interface 422 communicates with the third cavity 413. At this time, the first gas interface 414 serves as the first vent 321 of the pressure relief channel 32, the second gas interface 421 serves as the second vent 322 of the pressure relief channel 32, the first liquid interface 415 serves as the first liquid inlet 331 of the liquid suction channel 33, and the second liquid interface 422 serves as the second liquid inlet 332 of the liquid suction channel 33.

[0036] Further, see Figure 6 and Figure 7 The connecting assembly 4 also includes a connecting connector 43. The bottom of the connecting connector 43 has a third gas port 431 connected to the second gas port 421, and the top of the connecting connector 43 has a fourth gas port 432 connected to the third gas port 431. The bottom of the connecting connector 43 has a third liquid port 433 connected to the second liquid port 422, and the top of the connecting connector 43 has a fourth liquid port 434 connected to the third liquid port 433. The fourth liquid port 434 can also be connected to the liquid inlet 312 of the suction nozzle 31. In this case, the fourth gas port 432 is the second vent 322 of the pressure relief channel 32, and the fourth liquid port 434 is the second liquid inlet 332 of the suction channel 33. Furthermore, the gas port responsible for gas flow and the liquid port responsible for liquid flow can be located on the same connecting connector 43 or on two separate connecting connectors 43; this is not limited here.

[0037] Further, see Figure 6 and Figure 7The connecting component 4 also includes a sealing element 44. The sealing element 44 is installed at the bottom of the base 41, located between the first gas interface 414 and the drinking spout 21. The sealing element 44 has gas through holes 441, which are connected to both the first gas interface 414 and the drinking spout 21. In this embodiment, the first gas interface 414 is inserted into the upper end of the gas through holes 441, thereby installing the sealing element 44 at the bottom of the base 41. Furthermore, the sealing element 44 is made of an elastic material, and its bottom surface is in contact with the top surface of the drinking spout 2, thus providing a sealing effect. Simultaneously, the lower end of the gas through holes 441 is opposite to the drinking spout 21, and the diameter of the lower end of the gas through holes 441 is smaller than the diameter of the drinking spout 21. At this time, the gas through holes 441 serve as the first vent 321 of the pressure relief channel 32.

[0038] Additionally, the sealing element 44 is located between the first liquid interface 415 and the straw interface 22. The sealing element 44 has a liquid through hole 442, which is connected to both the first liquid interface 415 and the straw interface 22. In this embodiment, the first liquid interface 415 is inserted into the upper end of the liquid through hole 442, thereby installing the sealing element 44 at the bottom of the base 41. Furthermore, the sealing element 44 is made of an elastic material, and its bottom surface is in contact with the top surface of the drinking cap 2, thus enabling the sealing element 44 to perform a sealing function. At the same time, the lower end of the liquid through hole 442 is opposite to the straw interface 22, and the diameter of the lower end of the liquid through hole 442 is smaller than the diameter of the straw interface 22. In this case, the liquid through hole 442 is the first liquid outlet 331 of the liquid suction channel 33. In other embodiments, the liquid through hole 442 and the gas through hole 441 can be provided on the same sealing element 44, or they can be provided on two separate sealing elements 44, which is not limited here.

[0039] In one embodiment, see Figure 8 The double-drink cup also includes a sealing gasket 6. The sealing gasket 6 is installed on the spout cover 3 and is connected to the connecting joint 43 of the connecting assembly 4. The sealing gasket 6 is located between the spout 31 and the connecting assembly 4. The sealing gasket 6 has a vent 61, which is adapted to the plug 311 of the spout 31 and communicates with the second cavity 412 of the base 41. The sealing gasket 6 also has a liquid inlet 62, which communicates with the spout 31 and the third cavity 413 of the base 41. In this embodiment, the fourth gas port 432 of the connecting joint 43 is inserted into the lower end of the vent 61, and the fourth liquid port 434 of the connecting joint 43 is inserted into the lower end of the liquid inlet. At this time, the vent 61 is the second vent 322 of the pressure relief channel 32, and the liquid inlet is the second liquid port 332 of the suction channel 33. Furthermore, the sealing gasket 6 is made of elastic material, and the top surface of the sealing gasket 6 is in contact with the pivot of the suction nozzle 31, which can seal the liquid exchange hole and the liquid inlet 312 of the suction nozzle 31.

[0040] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
