[0020] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0021] Please refer to Figures 1 to 3 , an insulated water cup, comprising an upper cover 1, a lower cover 2, an insulated water outlet structure, and a cup body 6, wherein the upper cover 1 is connected to the lower cover 2 via a rotating shaft, the cup body 6 is a semi-sealed structure with one end open, and liquid can be stored inside it, the lower cover 2 is arranged on the open mouth, and the lower cover 2 is provided with an opening at the open mouth, the insulated water outlet structure is arranged between the cup body 6 and the lower cover 2 to cover the open mouth, the insulated water outlet structure comprises an inner plug 3 and a blocking body 4, one end of the blocking body 4 is a blocking part, and the other end is a protruding hollow straw part 41, the straw part 41 passes through the blocking part, the inner plug 3 is a hollow cylinder, the upper end of which is connected to the opening of the lower cover 2, and the lower end is connected to the blocking part, the straw part 41 passes through the inner plug 3 to form a stable water outlet and heat preservation structure.

[0022] Furthermore, a connecting plane is provided at the upper end of the inner plug 3 , and the connecting plane is buckled and connected to the opening of the lower cover 2 .

[0023] Furthermore, a water outlet 31 and an air outlet 32 ​​are provided on the connection plane, and the suction pipe portion 41 can pass through the water outlet 31 .

[0024] From the above description, it can be seen that the blocking body 4 and the inner plug 3 constitute a water outlet and heat preservation structure, that is, one end of the blocking body 44 is a blocking part, and the other end is a straw part 41. The inner plug 3 is a hollow structure, the blocking part is connected to the lower end of the inner plug 3, and the straw part 41 passes through the inner plug 3. The hollow inner plug 3 can form a heat preservation chamber, thereby reducing heat transfer and improving the heat preservation effect. The blocking part is used to seal the opening of the cup body 6. Because the straw part 41 is connected to the blocking part, when drinking is needed, the liquid in the cup body 6 can be sucked through the straw part 41, so that the heat preservation water outlet structure can achieve the dual functions of water outlet and heat preservation.

[0025] Furthermore, a plurality of one-way valves are provided on the blocking body 4 .

[0026] Furthermore, the number of the one-way valves is 2 or more.

[0027] Furthermore, the one-way valve is arranged on the suction tube portion 41 and / or the blocking portion.

[0028] Furthermore, the one-way valve includes one-way valve 1 42 and one-way valve 2 43 .

[0029] From the above description, it can be seen that the sealing body 4 is the core component for sealing and insulation. A one-way valve is arranged on it, which is conducive to the liquid or gas pressure in the cup body 6 being within a reasonable range, making drinking smoother, and can also release pressure in time when there is high pressure in the cup body 6.

[0030] Furthermore, the pressure-bearing capacity of the one-way valve 1 42 is greater than that of the one-way valve 2 43 .

[0031] From the above description, it can be known that the pressure-bearing capacity of the one-way valve 1 42 is greater than that of the one-way valve 2 43, that is, under the same pressure, the one-way valve 2 43 will open before the one-way valve 1 42, so that the pressure can be released in time through the one-way valve 2 43 to prevent high-temperature and high-pressure liquid or gas from spraying out from the straw part 41 where the one-way valve 1 42 is provided, thereby preventing accidental scalding.

[0032] Furthermore, the straw portion 41 has a tendency to bend.

[0033] From the above description, it can be seen that the straw portion 41 has a bending tendency, that is, the straw portion 41 has an inclined angle, which is not only convenient for drinking, but also can be bent and squeezed by the upper cover 1 when sealing is required to achieve the effect of intercepting and sealing.

[0034] Furthermore, the straw portion 41 has an enlarged plug-in portion 44 , and the plug-in portion 44 is connected to the extension tube 5 .

[0035] It can be seen from the above description that the provision of the extension tube 5 can achieve the technical effect of facilitating drinking.

[0036] like Figures 1 to 3 As shown, a thermos cup includes an upper cover 1, a lower cover 2, a heat preservation water outlet structure, and a cup body 6. The upper cover 1 is connected to one end of the lower cover 2 via a rotating shaft, and the upper cover 1 can rotate along the rotating shaft. The cup body 6 is a semi-sealed structure with one end open, and liquid can be stored inside. The lower cover 2 is arranged on the open end, and an opening is arranged on the side of the lower cover 2 facing the open end, and the lower cover 2 and the cup body 6 are connected by threads. In an optional embodiment, the cup body 6 can be a stainless steel thermos cup, a water cup with a heat preservation liner, or other water cups covered with heat preservation materials.

[0037] In order to improve the heat preservation and portability of the thermos cup, the utility model is provided with a heat preservation water outlet structure between the cup body 6 and the lower cover 2, and the heat preservation water outlet structure has the dual functions of water outlet and heat preservation.

[0038] like Figure 1 As shown, the water outlet insulation structure includes an inner plug 3 and a blocking body 4. The inner plug 3 is a hollow cylinder, and its upper end is a connecting plane 35, and its lower end is an annular end face 34. The connecting plane 35 is provided with a water outlet 31 and an exhaust port 32. The connecting plane 35 of the inner plug 3 passes through the opening of the lower cover 2 and is connected with the lower cover 2 by snapping. In a specific embodiment, a buckle 33 is provided at the upper end of the inner plug 3, and the inner plug 3 is connected with the lower cover 2 via the buckle 33. One end of the blocking body 4 is a blocking part, which is used to seal the internal opening of the cup body 6. The other end of the blocking body 4 is a protruding hollow straw part 41, and the straw part 41 is connected with the blocking part. When connected, the straw part 41 on one side of the blocking body 4 passes through the water outlet 31 of the inner plug 3, and the two are firmly connected by interference fit. The sealing portion on the other side of the sealing body 4 is fixedly connected to the annular end surface 34 of the inner plug 3, thereby forming a water outlet and heat preservation structure with dual functions of water outlet and heat preservation.

[0039] Preferably, the upper cover 1 is provided with a supporting portion, which plays a role in squeezing the straw portion 41 after the upper cover 1 is closed, and the straw portion 41 achieves a flow-cutting and sealing effect under the squeezing of the supporting portion.

[0040] When the insulated water cup with the above structure is used, the cup body 6 is filled with liquid that needs to be insulated, and the lower cover 2 is tightened. With the help of the sealing of the sealing part, the insulation effect is achieved, and the liquid is sealed in the cup body 6. In addition, the inner plug 3 is a hollow structure, which can form an insulation chamber to reduce heat transfer. When drinking is needed, since the straw part 41 and the inside of the cup body 6 are in a through state, at this time, only the upper cover 1 needs to be opened, and the liquid in the cup body 6 can be sucked through the straw part 41. In this way, the dual effects of water discharge and heat preservation are achieved, which not only improves the insulation effect, but also increases the convenience of use.

[0041] In some embodiments, Figure 1 As shown, the straw portion 41 has a plug-in portion 44, and the plug-in portion 44 is sleeved with an extension tube 5. The extension tube 5 can achieve the technical effect of facilitating drinking. In a preferred embodiment, the extension tube 5 and the plugging body 4 are both made of silicone, and the wall thickness of the extension tube 5 is 0.5-1.5 mm. The cross-sectional thickness of the plugging portion of the plugging body 4 is 2-5 mm, and the diameter of the plugging portion is slightly larger than the internal opening of the cup body 6. The plugging portion and the internal opening are interference-fitted to form an internal sealed space with good heat preservation effect, thereby improving the heat preservation effect of the water cup.

[0042] In some embodiments, Figure 2 As shown, in order to improve the user experience of the thermos cup, a one-way valve is provided on the blocking body 4. In this embodiment, the one-way valve is preferably a valve-type one-way valve. Figure 3 As shown, the one-way valve includes a one-way valve 42 and a one-way valve 43. The one-way valve 42 is arranged on the straw portion 41, and the one-way valve 43 is arranged on the blocking portion. The one-way valve 42 and the one-way valve 43 have the same one-way characteristic, that is, the conduction direction is consistent. In the specific embodiment, both are conducted toward the inside of the cup body and not conducted toward the outside of the cup body.

[0043] In an alternative embodiment, if Figure 3 As shown, the model or specification of the one-way valve 1 42 is larger than that of the one-way valve 2 43, and the valve membrane constituting the one-way valve is also thicker than that of the one-way valve 1 42. The purpose of such a setting is that the one-way valve 2 43 opens before the one-way valve 1 42 under the same pressure. In a specific application scenario, when there is a high-temperature, high-pressure liquid or gas in the cup body 6, because the one-way valve 2 43 opens before the one-way valve 1 42 under the same pressure, the one-way valve 2 43 can be used to release the pressure in time, preventing the high-temperature, high-pressure liquid or gas from being sprayed out from the straw part 41 where the one-way valve 1 42 is set, and preventing accidental scalding.

[0044] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
