The middle of the holder 8 is provided with a step, the bottom of the holder 8 is provided with an external thread, the top of the base 13 is provided with an internal thread, the holder 8 and the base 13 are threadedly connected, and tightening the thread ensures that the holder 8 and the cup cover 11 are sealed.

[0046] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 , Figure 5 and Fig.10 An air inlet 20 is provided on one end of the surface of the base 8 near the third sealing ring 10, and a vent hole is provided on the cup cover 11, and the air inlet 20 is communicated with the vent hole. Air flows along the gap between the nozzle body 3 and the base 8, along the air inlet 20 on the surface of the base 8, and along the air inlet provided on the cup cover 11 into the interior of the cup body 15, forming air convection.

[0047] Please refer to the attached figure in the instruction manual Figure 3 , Figure 4 , Figure 8 and Fig. 9The nozzle body 3 is installed inside the card seat 8, and the top of the rotating sleeve 2 is clamped with the silicone dust cover 1. The top of the silicone dust cover 1 is provided with a cross cut, and the size of the cross cut is larger than the diameter of the nozzle body 3. The cross cut makes it easy for the nozzle body 3 to extend out of the silicone dust cover 1 or retract into the silicone dust cover 1. When the nozzle body 3 is extended, a certain gap is ensured between it and the silicone dust cover 1.

[0048] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 , Figure 4 , Figure 7 , Fig.10 and Fig.13 , a first sealing ring 5 is sleeved on the middle part of the outer side of the nozzle body 3. When the nozzle body 3 is retracted, the first sealing ring 5 contacts the holder 8 to form a seal to prevent liquid leakage. A silicone plug 7 is connected to the bottom of the nozzle body 3, and a second sealing ring 6 is sleeved on one end of the outer side of the nozzle body 3 close to the silicone plug 7. When the nozzle body 3 is extended, the silicone plug 7 is separated from the base 13 to release the seal, which is convenient for sucking liquid. At this time, the second sealing ring 6 contacts the holder 8 to form a seal, so that a seal is formed between the nozzle body 3, the holder 8 and the base 13, ensuring that there will be no leakage when sucking liquid. When the nozzle body 3 is retracted, the silicone plug 7 contacts the base 13 to achieve the sealing function.

[0049] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 , Figure 7 and Fig.10 The outer diameter of the first sealing ring 5 is smaller than the outer diameter of the middle of the nozzle body 3, a gap is provided between the first sealing ring 5 and the holder 8, a gap is provided between the holder 8 and the rotating sleeve 2, a gap is provided between the rotating sleeve 2 and the cup cover 11, a gap is provided between the middle of the nozzle body 3 and the holder 8, and a plurality of grooves 16 are provided in the middle of the nozzle body 3. The smoothness of air intake is ensured, and the provision of the grooves 16 makes the air intake more unobstructed.

[0050] Please refer to the attached figure in the instruction manual Figure 1 , Figure 2 , Figure 7 and Fig.13 A water level line 19 is arranged at the upper end of the inner wall of the cup body 15, and the end of the base 13 away from the straw 14 is arranged to be larger at the top and smaller at the bottom. The outer diameter of the silicone plug 7 is larger than the inner diameter of the lower part of the base 13, and the position where the base 13 is larger at the top and smaller at the bottom is parallel to the water level line 19. When the liquid in the cup body 15 is at a high water level, the suction nozzle body 3 contracts to press the liquid back into the cup body 15, so as to prevent excessive liquid from remaining above the silicone plug 7, causing liquid to seep out or remain between the suction nozzle body 3 and the holder 8 and between the holder 8 and the rotating sleeve 2 when the cup body 15 is tilted later.

[0051] Please refer to the attached figure in the instruction manual Figure 1 , Figure 6 , Fig.11 and Fig.12 A circular pin 4 is connected to the middle part of the outer side of the nozzle body 3, a guide groove 9 matching the circular pin 4 is opened on the surface of the holder 8, a spiral guide groove 17 matching the circular pin 4 is opened on the inner wall of the rotating sleeve 2, and the circular pin 4 extends from the guide groove 9 and is inserted into the spiral guide groove 17.

[0052] Please refer to the attached figure in the instruction manual Figure 2 , Figure 5 and Figure 7 , the top and bottom of the holder 8 are provided with transverse guide grooves 18. The transverse guide grooves 18 provided at the bottom can fix the nozzle body 3 when the nozzle body 3 is retracted, ensure that the silicone plug 7 is in close contact with the base 13, and ensure that the nozzle body 3 will not be affected by the rebound force of the silicone plug 7 to cause unstable sealing or sealing failure. The transverse guide grooves 18 provided at the top can fix the nozzle body 3 when the nozzle body 3 is extended, ensure that the second sealing ring 6 at the bottom of the nozzle body 3 is in close contact with the bottom of the holder 8, and ensure that the nozzle body 3 will not be affected by the rebound force of the silicone plug 7 to cause unstable sealing or sealing failure.

[0053] Working principle: When drinking water, rotate the rotating sleeve 2 forward. At this time, the circular pin 4 on the nozzle body 3 slides upward along the spiral guide groove 17 on the inner side of the rotating sleeve 2 until the nozzle body 3 extends out and pushes open the cross cut on the silicone dust cover 1. At this time, there is a certain gap between the nozzle body 3 and the silicone dust cover 1, and the silicone plug 7 is separated from the base 13 to release the seal. The liquid in the cup body 15 can be smoothly sucked through the straw 14 and the nozzle body 3. The groove 16 set in the middle of the nozzle body 3 makes the air intake more unobstructed, and when the nozzle body 3 is extended, the second sealing ring 6 contacts the holder 8 to form a seal, so that a seal is formed among the nozzle body 3, the holder 8 and the base 13, ensuring that there will be no leakage when sucking liquid.

[0054] When you don't need to drink water, rotate the rotating sleeve 2 in the opposite direction. At this time, the circular pin 4 on the nozzle body 3 slides downward along the spiral guide groove 17 on the inner side of the rotating sleeve 2 to drive the nozzle body 3 to contract. When the nozzle body 3 contracts, the silicone plug 7 contacts the base 13 to achieve a seal. At this time, the third sealing ring 10 on the outside of the holder 8 contacts the cup cover 11 to form a seal, the first sealing ring 5 on the nozzle body 3 contacts the holder 8 to form a seal, and the fourth sealing ring 12 on the cup cover 11 contacts the cup body 15 to form a seal, ensuring that the liquid in the cup body 15 does not overflow.

[0055] In the present invention, the rotating sleeve 2 serves as a part of the operating interface. The rotating sleeve controls the extension and retraction of the nozzle body by forward and reverse rotation, allowing the user to easily control the position of the nozzle, ensuring convenient use while reducing the risk of accidentally touching the nozzle.

[0056] The portion of the nozzle body 3 that directly contacts the user's oral cavity is a retractable structure and can be hidden after use, which reduces the chance of contact with bacteria and other pollutants and improves the overall hygiene level.

[0057] The circular pin 4 and the spiral guide groove 17 enable the nozzle body to be extended and retracted. The circular pin can move in the spiral guide groove, and the nozzle body can be pushed or pulled by the rotation of the rotating sleeve.

[0058] The silicone dust cover 1 is located outside the nozzle body and is used to close the opening when the nozzle body is hidden to prevent dust and pollutants from entering.

[0059] When the nozzle body is extended, the second sealing ring 6 contacts the holder 8 to form a seal, thereby ensuring that the inside of the system maintains a good sealing state when sucking liquid, avoiding air leakage and ensuring stable suction.

[0060] When the parts need to be cleaned, due to the threaded connection between the cup cover 11 and the cup body 15, it is convenient to remove the cup cover 11 from the cup body 15 and clean the inside of the cup body 15 later. At the same time, the bottom of the holder 8 is provided with an external thread, and the upper part of the base 13 is provided with an internal thread. The holder 8 and the base 13 are threadedly connected, so that it is convenient to disassemble the holder 8 and the base 13 later, and remove the straw 14 from the base 13, so that the suction nozzle has a detachable function.

[0061] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
