DETAILED DESCRIPTION

[0023] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-5 As shown, the utility model describes a retractable straw structure for a water cup, comprising a cup body 1, a cup cover 2, a water guide pipe 21 and an elastic straw 3, wherein the upper end of the water guide pipe 21 is fixedly connected to the cup cover 2, and the elastic straw 3 is passed through the water guide pipe 21 and fixedly connected thereto; a first retaining ring 34 is provided on the outer wall of the elastic straw 3, a constricting ring 23 is provided in the upper end of the water guide pipe 21, and the first retaining ring 34 is connected to the constricting ring 23 by abutting contact.

[0025] The utility model is a device for drinking water, especially for drinking iced water / beverages. The cup body 1 is used to hold water and beverages, and the cup cover 2 is sealed on the cup body 1. Of course, a sealing ring is provided between the cup cover 2 and the cup mouth of the cup body 1 to prevent water leakage. The upper end of the water guide pipe 21 passes through the cup cover 2, and the lower end of the water guide pipe 21 is connected to the inner cavity of the cup body 1. The elastic straw 3 is inserted into the water guide pipe 21, and the upper end of the elastic straw 3 passes through the upper end of the water guide pipe 21 and is exposed and arranged on the cup cover 2. The lower end of the elastic straw 3 can be installed with an extension straw, so as to facilitate the user to drink the water or beverage in the cup body 1.

[0026] In particular, the elastic straw 3 is made of a flexible silicone material, which has the ability to deform, and the elastic straw 3 can be compressed / folded so as to be stored in the water guide pipe 21, so as to avoid the elastic straw 3 being exposed and contaminated. Of course, the elastic silicone straw 3 can rebound by itself and be extended again to be set on the cup cover 2.

[0027] It is understandable that the deformation action of the elastic straw 3 is usually folding, contracting and bending. Preferably, the elastic straw 3 adopts a foldable structure to shorten its own length, such as a bellows structure. After being folded, the elastic straw 3 can compress the area of ​​the inner wall, reduce the liquid residue on the inner wall of the elastic straw 3, and avoid hygiene risks.

[0028] Preferably, a cinch ring 23 is provided at the upper end of the water pipe 21, and when the elastic straw 3 stretches upward, the first stop ring 34 contacts the cinch ring 23 to form a limit, thereby preventing the elastic straw 3 from overstretching. Furthermore, the elastic straw 3 has elastic force, thereby providing potential energy to the first stop ring 34, so that it fits tightly against the cinch ring 23, and the first stop ring 34 and the cinch ring 23 cooperate to close the upper end of the water pipe 21, thereby preventing residual water and dust from entering the cup body 1 through the gap between the water pipe 21 and the elastic straw 3.

[0029] The elastic straw 3 includes a water suction nozzle 31, a first telescopic part 32 and a transfer tube 33 which are sequentially connected from top to bottom. The transfer tube 33 is connected with the water diversion pipe 21. A first baffle ring 34 is provided at the upper end of the first telescopic part 32. When the first telescopic part 32 is unfolded, the first baffle ring 34 touches the connecting cuff ring 23. When the first telescopic part 32 is folded, the water suction nozzle 31 and the first baffle ring 34 are accommodated in the water diversion pipe 21.

[0030] Preferably, the first telescopic portion 32 is a bellows structure, and the lower end of the first telescopic portion 32 is connected to the adapter tube 33, so that the water suction nozzle 31 is exposed and arranged on the cup cover 2 or retracted and arranged in the water guide pipe 21. The adapter tube 33 is used to install an extension straw, and the extension straw extends into the inner cavity of the cup body 1.

[0031] The first retaining ring 34 cooperates with the water diversion pipe 21 , and the first retaining ring 34 slides up and down along the water diversion pipe 21 , thereby controlling the deformation trajectory of the first telescopic portion 32 .

[0032] A second stop ring 35 is provided at the lower end of the first telescopic portion 32, and a stopper structure is provided in the water guide pipe 21, and the second stop ring 35 contacts and connects with the stopper structure. The stopper structure is provided near the lower end of the water guide pipe 21, and after the second stop ring 35 contacts the stopper structure, the second stop ring 35 and the stopper structure can also play the role of closing the lower end of the water guide pipe 21, preventing the water in the cup body 1 from entering the water guide pipe 21 when drinking water in large gulps or when the cup body 1 is tilted.

[0033] The lower end of the water pipe 21 is sleeved with a fixed cap 22, and the transfer pipe 33 is inserted into the fixed cap 22 and fixedly connected thereto, and a reflux port 24 is provided on the fixed cap 22; a second telescopic portion 36 is provided between the first telescopic portion 32 and the transfer pipe 33, and a second retaining ring 35 is provided on the outer wall of the second telescopic portion 36, and the lower end of the water pipe 21 constitutes a stopper structure, and when the second telescopic portion 36 is expanded, the second retaining ring 35 contacts the lower end of the water pipe 21. The transfer pipe 33 cooperates with the fixed cap 22 to fix the elastic suction pipe 3 with the water pipe 21, and the first telescopic portion 32 adopts a bellows structure, so that the water suction nozzle 31 can be telescoped up and down relative to the transfer pipe 33. The fixed cap 22 is sleeved on the water pipe 21, so that the second retaining ring 35 can fit the lower end of the water pipe 21 upward, thereby sealing the lower end of the gap channel between the elastic suction pipe 34 and the water pipe 21, and preventing the water in the cup body 1 from leaking from the gap between the two.

[0034] In particular, the second telescopic portion 36 is also a bellows structure, and when the second telescopic portion 36 is deformed, the second retaining ring 35 can move up and down between the lower end of the water pipe 21 and the lower end of the fixing cap 22. The elastic straw 3 is elastic, and its extension length is greater than the length of the water pipe 21. Therefore, the first retaining ring 34 and the second retaining ring 35 respectively control the extension range of the first telescopic portion 32 and the second telescopic portion 36, and control the exposed height of the water suction nozzle 31 on the cup cover 2.

[0035] Furthermore, the fixing cap 22 is provided with a reflux port 24, and the outer edge diameter of the second retaining ring 35 is smaller than the inner cavity diameter of the fixing cap 22. After the elastic straw 3 is folded and retracted into the water guide pipe 21, if there is water in the water guide pipe 21, it can return to the cup body 1 from the reflux port 24. The fixing cap 22 is sleeved on the lower end of the water guide pipe 21 through a detachable assembly structure. It is understandable that the transfer tube 33 and the fixing cap 22 can be assembled using processes such as snap-fit, bonding, injection molding, and ultrasonic connection.

[0036] The fixing cap 22 is sleeved on the lower end of the water pipe 21 through a detachable assembly structure. The preferred assembly structure includes a threaded connection and a snap-on structure. The fixing cap 22 can be fixedly connected to the elastic straw 3, and then the elastic straw 3 can be installed in the water pipe 21. Of course, the detachable fixing cap 2 can facilitate the cleaning of the elastic straw 3.

[0037] The cup cover 2 is provided with a sealing cover 4, a hinge 42 and a lock 41, one end of the sealing cover 4 is rotatably connected to the cup cover 2 through the hinge 42; the cup cover 2 is provided with a keyhole position 25, the lock 41 is movably installed on the keyhole position 25, and the other end of the sealing cover 4 is detachably connected to the lock 41 through a fastener; when the sealing cover 4 is covered on the cup cover 2, the sealing cover 4 squeezes the elastic straw 3 to make it stored in the water guide pipe 21. Preferably, the hinge 42 is also provided with a torsion spring, and after the lock 41 unlocks the sealing cover 3, the torsion spring can make the sealing cover 4 automatically pop up, and further, the elastic straw 3 will also automatically pop out of the cup cover 2, so that the user can drink the water or beverage in the cup body 1.

[0038] A sealing gasket 43 is provided inside the sealing cover 4. When the sealing cover 4 is covered on the cup cover 2, the sealing gasket 43 fits the cup cover 2 to cover the upper end of the water guide pipe 21. When the sealing cover 4 is covered on the cup cover 2, the lock buckle 41 locks it with the cup cover 2, and the water suction nozzle 31 is compressed downward into the water guide pipe 21. The sealing gasket 43 can seal the upper end surface of the cup cover 2 and surround the upper end of the water guide pipe 21 to prevent water leakage in the cup body 1.

[0039] The sealing cover 4 is provided with an ejector pin 44, and the cup cover 2 is provided with an air return hole 26. When the sealing cover 4 is closed on the cup cover 2, the ejector pin 44 is inserted into the air return hole 26. When the sealing cover 4 on the cup cover 2 is opened, the ejector pin 44 is withdrawn from the air return hole 26, and the inner cavity of the cup body 1 is connected to the outside through the air return hole 26. When the user drinks water through the elastic straw 3, no negative pressure will appear in the cup body 1.

[0040] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
