[0043] Referring to the description of the present invention Figures 1 to 8 , a straw cup according to a preferred embodiment of the present invention will be disclosed and described hereinafter. The straw cup includes a cup body 10, a straw 20, and a straw cup lid assembly 30. The straw cup lid assembly 30 is mounted on the cup body 10, and the straw 20 is mounted on the straw cup lid assembly 30.

[0044] The specific structure of the cup body 10 is not limited in the straw cup of the present invention. For example, in the specific example of the straw cup shown in Figures 1 to 8 , the cup body 10 includes a cup 11 and at least one handle 12. The handle is integrally connected to the outer wall of the cup 11. The cup body 10 has a cup body space 13 formed in the cup 11. Preferably, there are two handles 12, and the two handles 12 are respectively arranged on opposite sides of the cup 11.

[0045] The straw cup lid assembly 30 includes a straw cup lid 31 and an auxiliary cup lid 32. The straw cup lid 31 has a straw passage 311. After the straw cup lid 31 is installed on the cup body 10, the straw passage 311 of the straw cup lid 31 communicates with the cup body space 13 of the cup body 10. The straw 20 is installed in the straw passage 311 of the straw cup lid assembly 30. One end of the straw 20 extends into the cup body space 13 of the cup body 10, and the other end can protrude above the straw cup lid assembly 30 to allow a user to drink the water contained in the cup body space 13 of the cup body 10 through the straw 20. The auxiliary cup lid 32 has a pivot end 321 and an operation end 322 that are opposite to each other. The pivot end 321 of the auxiliary cup lid 32 is rotatably installed on the top of the straw cup lid 31. The operation end 322 of the auxiliary cup lid 32 is configured to be able to cover the straw passage 311 of the straw cup lid 31, and the straw 20 is sealed in the straw passage 311 of the straw cup lid 31 by the auxiliary cup lid 32 to prevent the liquid in the cup body 10 from flowing out through the straw 20, facilitating the user to carry drinking water with the straw cup.

[0046] The straw cup lid assembly 30 includes a locking device 33. The locking device 33 is provided on one of the straw cup lid 31 and the auxiliary cup lid 32, and the locking device 33 is configured to be able to lock or release the other of the straw cup lid 31 and the auxiliary cup lid 32.

[0047] For example, in one specific embodiment shown in the present utility model shown in the appendix Figures 1 to 8 In one specific embodiment shown in the present utility model shown in the appendix, the locking device 33 is provided on the auxiliary cup lid 32, and the locking device 33 is able to lock or release the straw cup lid 31. When the locking device 33 locks the auxiliary cup lid 32 and the straw cup lid 31 to each other, the operation end 322 of the auxiliary cup lid 32 closes the opening of the straw 20 to prevent the water contained in the cup body space 13 of the cup body 10 from flowing out through the straw 20. When the locking device 33 releases the straw cup lid 31, the auxiliary cup lid 32 can be opened to expose the straw 20. At this time, the user can drink the water contained in the cup body space 13 of the cup body 10 through the straw 20.

[0048] In the appendix Figures 1 to 8In this specific example of the straw cup of the present utility model shown, the straw cup lid 31 includes a main lid element 312 integrally formed and an extension tube 313 extending upward from the side wall of the main lid element 312. The main lid element 312 is installed on the cup body 10 of the straw cup. The extension tube 313 extends a boss 3131 in the circumferential direction. The locking device 33 includes a locking element 331. The locking element 331 has a locking end 3311. The locking end 3311 of the locking element 331 can move below the boss 3131 of the extension tube 313 or move away from below the boss 3131 of the extension tube 313.

[0049] Specifically, the straw channel 311 of the straw cup lid 31 is formed in the extension tube 313. The pivot end 321 of the auxiliary cup lid 32 is rotatably provided on the main lid element 312. When the locking end 3311 of the locking element 331 moves below the boss 3131 of the extension tube 313, the locking device 33 locks the straw cup lid 31. The operating end 322 of the auxiliary cup lid 32 closes the top opening of the extension tube 313. The straw 20 installed in the straw channel 311 of the straw cup lid 31 is received in the straw channel 311 of the straw cup lid 31, and the top of the straw 20 abuts against the inner wall of the operating end 322 of the auxiliary cup lid 32. The opening of the straw 20 is closed by the auxiliary cup lid 32, preventing the straw 20 from moving up and down in the straw channel 311 of the straw cup lid 31 when the user carries the straw cup, and also preventing the water in the cup space 13 of the cup body 10 from flowing out through the straw 20. When the locking end 3311 of the locking element 331 moves away from below the boss 3131 of the extension tube 313, the locking device 33 releases the straw cup lid 31. At this time, the operating end 322 of the auxiliary cup lid 32 is driven to disengage from the top opening of the extension tube 313. The user can rotate the pivot end 321 of the auxiliary cup lid 32 relative to the main lid element 312 to completely expose the top opening of the extension tube 313 of the straw cup lid 31, making the straw 20 protrude. The user can drink the water contained in the cup space 13 of the cup body 10 through the straw 20.

[0050] Reference Figure 6As shown, the auxiliary cup cover 32 has a locking cavity 323 and a through hole 324 that communicate with each other at the pivoting end 321. The locking element 331 of the locking device 33 is installed in the locking cavity 323 of the auxiliary cup cover 32, and the locking end 3311 is located in the through hole 324 of the auxiliary cup cover 32. The locking element 331 of the locking device 33 can move left and right in the locking cavity 323. The through hole 324 of the auxiliary cup cover 32 can limit the movement path of the locking element 331 of the locking device 33, so that the locking element 331 of the locking device 33 can only move left and right in the locking cavity 323 of the auxiliary cup cover 32, ensuring that the locking end 3311 of the locking element 331 can move below the boss 3131 of the extension tube 313.

[0051] Optionally, in other examples of the straw cup of the present invention, the locking element 331 of the locking device 33 can be entirely located in the locking cavity 323 of the auxiliary cup cover 32. When the locking element 331 moves in the locking cavity 323 of the auxiliary cup cover 32, the locking end 3311 of the locking element 331 can move below the boss 3131 of the extension tube 313 or move away from below the boss 3131 of the extension tube 313 through the through hole 324 of the auxiliary cup cover 32.

[0052] Refer to the attached Figure 5 , the locking element 331 has two limiting platforms 3312 that longitudinally extend from the top and bottom of the locking element 331 at the locking end 3311. When the locking element 331 of the locking device 33 moves in the locking cavity 323 of the auxiliary cup cover 32, the limiting platforms 3312 will be blocked by the inner wall of the auxiliary cup cover 32 that defines the locking cavity 323 to limit the position of the locking element 331 moving in the locking cavity 323 of the auxiliary cup cover 32, preventing the locking device 33 from falling off the auxiliary cup cover 32.

[0053] Further, the locking device 33 further includes an elastic element 332. The elastic element 332 is disposed in the locking cavity 323 of the auxiliary cup cover 32, and opposite ends of the elastic element 332 respectively abut against an end of the locking element 331 away from the locking end 3311 and an inner wall of the auxiliary cup cover 32 that defines the locking cavity 323. For example, one end of the elastic element 332 can abut against the lower limiting platform 3312 of the locking element 331, so that this end of the elastic element 332 abuts against the end of the locking element 331 away from the locking end 3311. It can be understood that since the elastic element 332 is located in the locking cavity 323 of the auxiliary cup cover 32, the elastic element 332 is hidden and visually invisible.

[0054] When the auxiliary cup cover 31 is switched from the open state to covering the top opening of the extension tube 313 of the straw cup cover 31 (i.e., the closed state), the boss 3131 of the extension tube 313 drives the locking end 3311 of the locking element 331 to allow the locking element 331 to move relative to the straw cup cover 31. At this time, the limiting platform 3312 and the inner wall of the auxiliary cup cover 31 squeeze the elastic element 332, and the elastic element 332 accumulates elastic potential energy due to deformation; when the operating end 322 of the auxiliary cup cover 32 covers and seals the opening of the straw 20, the locking element 331 of the locking device 33 moves towards the main cover element 312 via the outer ring of the boss 3131. During the process of the elastic element 332 restoring to its initial state, it drives the locking end 3311 of the locking element 331 to move below the boss 3131, so that the locking device 33 automatically locks the straw cup cover 31, that is, the user can interlock the auxiliary cup cover 32 with the straw cup cover without manually moving the locking device 33, and realize sealing the opening of the straw 20 through the auxiliary cup cover 31.

[0055] It is worth mentioning that the boss 3131 of the extension tube 313 has a first driving inclined surface 31311, and the end of the locking end 3311 of the locking element 331 has a first driven inclined surface 33111. The first driving inclined surface 31311 of the boss 3131 and the first driven inclined surface 33111 of the locking element 331 are mutually attached. The extending direction of the first driven inclined surface 33111 of the locking element 331 intersects with the horizontal plane, and the intersection point is located on the right side of the first driven inclined surface 33111 of the locking element 331. The included angle formed between the first driven inclined surface 33111 of the locking element 331 and the horizontal plane is less than 90 degrees, presenting an acute angle state. During the process that the pivot end 321 of the auxiliary cup cover 32 rotates to make the operating end 322 of the auxiliary cup cover 32 cover the top opening of the extension tube 313 of the straw cup cover 31, when the first driven inclined surface 33111 of the locking element 331 changes from a separated state to being mutually attached to the first driving inclined surface 31311 of the boss 3131, an external force drives the first driven inclined surface 33111 of the locking element 331 to slide along the first driving inclined surface 31311 of the boss 3131, so that the top end of the locking end 3311 of the locking element 331 passes through the outer ring wall of the boss 3131 to the lower part of the boss 3131.

[0056] For the sake of easy understanding, Figure 7 the opening process of the straw cup cover assembly 30 of the present utility model is shown, Figure 8 and the closing process of the straw cup cover assembly 30 of the present utility model is shown.

[0057] Specifically, referring to Figure 7 , the locking element 331 is installed in the locking cavity 323 of the auxiliary cup cover 32. The locking end 3311 of the locking element 331 is located in the through hole 324 of the locking cavity 323. The elastic element 332 makes the locking end 3311 of the locking element 331 be positioned below the boss 3131 of the extension tube 313. The limiting platform 3312 of the locking element 331 is attached to the inner wall of the auxiliary cup cover 32 for defining the locking cavity 323. At this time, the operating end 322 of the auxiliary cup cover 32 covers the opening of the straw 20, preventing the water in the cup body space 13 of the cup body 10 from flowing out through the straw 20.

[0058] When the user needs to open the auxiliary cup cover 32 to drink the water in the straw cup, by applying an external force, the locking element 331 of the locking device 33 moves along the locking cavity 323 of the auxiliary cup cover 32, and the locking end 3311 of the locking element 331 moves away from the boss 3131. At this time, the limiting platform 3312 at the bottom of the locking element 331 compresses the elastic element 332 located in the locking cavity 323, and the elastic element 332 accumulates elastic potential energy due to being compressed and deformed. When the locking end 3311 moves away from below the boss 3131 of the extension tube 313, the pivot end 321 of the auxiliary cup cover 32 can rotate relative to the main cover element 312. At this time, the operating end 322 of the auxiliary cup cover 32 moves away from the extension tube 313, and the top of the straw 20 protrudes from the extension tube 313 of the straw cup cover 31, and the user can drink the water in the cup body 10 through the straw 20.

[0059] Reference Figure 8 , after the auxiliary cup cover 32 covers the top opening of the extension tube 313, the user presses the auxiliary cup cover 32, and the first driven inclined surface 33111 of the locking end 3311 of the locking element 331 fits with the first driving inclined surface 31311 of the boss 3131 of the extension tube 313. Continuing to press the auxiliary cup cover 32 to drive the locking device 33 to move downward, the first driving inclined surface 31311 of the boss 3131 drives the locking end 3311 of the locking element 331 to move along the through hole 324 of the auxiliary cup cover 32, and the limiting platform 3312 of the locking end 3311 squeezes the elastic element 332 to deform and accumulate elastic potential energy; when an external force drives the locking end 3311 of the locking element 331 to move below the boss 3131, the elastic element 332 releases elastic potential energy to push the limiting platform 3312 of the locking end 3311 of the locking element 331 to move, so that the locking end 3311 of the locking element 331 moves below the boss 3131, allowing the locking device 33 to automatically lock the straw cup cover 31.

[0060] Figures 9 to 16 Another embodiment of the straw cup according to the present invention is shown. Different from the straw cup shown in the appendix Figures 1 to 8 shown, in this specific example of the straw cup shown in the appendix Figures 9 to 16 shown, the locking device 33 includes a pressing part 333, the pressing part 333 is movably arranged up and down in the locking cavity 323 of the auxiliary cup cover 32, and the top of the locking element 331 is drivingly connected to the pressing part 333.

[0061] When the user needs to use the straw cup to open the auxiliary cup cover 32, after the pressing part 333 is pressed downward by an external force, the pressing part 333 drives the locking element 331 to move in the locking cavity 323 of the auxiliary cup cover 32. The locking end 3311 of the locking element 331 moves away from below the boss 3131 and moves to a position where the end point of the locking end 3311 is spaced from the outer circle of the boss 3131. The auxiliary cup cover 32 rotates relative to the main cover element 312 to open the straw channel 311 of the straw cup cover 31, and the top of the straw 20 protrudes from the extension tube 313.

[0062] Preferably, the bottom of the pressing part 333 has a second driving inclined surface 3331, and the top of the locking element 331 has a second driven inclined surface 3313. The second driving inclined surface 3331 of the pressing part 333 and the second driven inclined surface 3313 of the locking element 331 are mutually attached.

[0064] Figure 15The opening process of the straw cup lid assembly 30 of the straw cup is shown. The locking end 3311 of the locking element 331 extends through the through hole 324 of the auxiliary cup lid 32 to the lower side of the boss 3131 of the extension tube 313 of the straw cup lid 31. The user presses down on the pressing portion 333 so that the second driving slope 3331 of the pressing portion 333 abuts against the second driven slope 3313 of the locking element 331. At the same time, the limiting platform 3312 of the locking element 331 compresses the elastic element 332 from left to right, causing the elastic element 332 to store elastic potential energy. The auxiliary cup lid 32 covering the extension tube 313 rotates relative to the main lid element 312. At this time, the operating end 322 of the auxiliary cup lid 32 moves away from the extension tube 313, and the top of the straw 20 protrudes from the extension tube 313 of the straw cup lid 31. The user can drink the water in the cup body 10 through the straw 20.

[0065] Figure 16 The locking process of the straw cup lid assembly 30 of the above-mentioned straw cup is shown. The user covers the auxiliary cup lid 32 onto the straw cup lid 31. The first driven slope 33111 of the locking end 3311 of the locking element 331 abuts against the first driving slope 31311 of the extension tube 313 and moves downward. At this time, the limiting platform 3312 of the locking element 331 squeezes the elastic element 332 from left to right, and the elastic element 332 stores elastic potential energy. When the position of the locking end 3311 of the locking element 331 corresponds to the space below the boss 3131 of the extension tube 313, during the process of the elastic element 332 releasing elastic potential energy, it pushes the locking end 3311 of the locking element 331 to move to the lower side of the boss 3131 of the extension tube 313. At this time, the locking device 33 locks the straw cup lid 31.
