They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting this application.

[0034] See also Figures 1 to 9The thermos cup shown in the figure includes a cup body 1, a cup cover 2, an insulating inner plug 5, a suction nozzle cover assembly and a straw 6, wherein the cup body 1 includes a cup body 11 and a cup mouth 12 located above the cup body 11, the inner diameter of the cup mouth 12 is smaller than the inner diameter of the cup body 11, and the insulating inner plug 5 can be cooperatively embedded in the cup mouth 12; the straw 6 is arranged in the inner cavity of the cup body 1, and the upper part of the suction nozzle 6 is detachably connected to the lower part of the insulating inner plug 5; the suction nozzle cover assembly includes a cover body 3 and a suction nozzle 4 detachably arranged on the cover body 3, the cover body 3 is detachably connected to the upper part of the cup body 1, so that the suction nozzle 4 is fixed above the cup body 1; the cup cover 2 is covered above the suction nozzle 4 and is detachably connected to the cover body 3, so that the suction nozzle 4 is placed as a whole in the closed space surrounded by the cup cover 2 and the cup body 1, protecting the suction nozzle 4 from contamination while avoiding heat loss.

[0035] Specifically, the thermal insulation inner plug 5 comprises a disc-shaped plug body 51, and a connecting body 52 extending upward from the middle of the plug body 51. A connecting hole 55 is also provided at the lower portion of the plug body 51. The thermal insulation inner plug 5 is also provided with a liquid flow hole 53 and an exhaust hole 54 extending in the vertical direction. The liquid flow hole 53 passes through the connecting body 52 and the plug body 51 in the vertical direction and is connected to the connecting hole 55. The exhaust hole 54 is provided on the plug body 51 and is spaced apart from the liquid flow hole 53. The suction nozzle 4 comprises a cover portion 41, a mouth portion 42, and a connecting portion 43. The cover portion 41 is provided above the cup mouth portion 12, the mouth portion 42 is located above the cover portion 41, and the connecting portion 43 extends downward from the lower portion of the mouth portion 42 and can be detachably connected to the connecting body 52. ​​The suction nozzle 4 has a communicating hole 44 passing through the mouth portion 42 and the connecting portion 43.

[0036] In this thermos cup, the upper part of the straw 6 is detachably connected to the connecting hole 55, so that the straw 6 is fixedly connected to the lower part of the thermal insulation inner plug 5; the straw 6 and the thermal insulation inner plug 5 are integrally arranged in the cup body 1, and the suction nozzle 4 is fixed to the top of the cup mouth 12 through the cover body 3, wherein the connector 52 on the upper part of the thermal insulation inner plug 5 is correspondingly inserted into the connecting part 43 of the suction nozzle 4, realizing a detachable connection between the thermal insulation inner plug 5 and the suction nozzle 4, and at the same time, the communicating hole 44 is interconnected with the liquid flow hole 53 and the tube cavity of the straw 6, so that children can obtain liquid in the inner cavity of the cup body 1 through the mouth 42.

[0037] In this thermos cup, the opening of the cup mouth 12 is basically blocked by the thermal insulation inner plug 5. The liquid in the inner cavity of the cup body 1 can only be transferred to the mouth 42 through the tube cavity of the straw 6, the liquid flow hole 53 of the thermal insulation inner plug 5 and the liquid flow hole 53. The cover part 41 of the suction nozzle 4 basically does not contact the liquid under the insulating effect of the thermal insulation inner plug 5, which can effectively keep the liquid in the inner cavity of the cup body 1 warm and keep its temperature unchanged for a long time. At the same time, the provided suction nozzle 4 makes the thermos cup meet the use needs of small children.

[0038] As shown in the accompanying drawings, in the thermos cup provided in this embodiment, the plug body 51 is integrally built into the inner cavity of the cup body 1, wherein the top periphery of the plug body 51 is located below the top periphery of the cup mouth 12, and the cup mouth 12 is completely blocked by the thermal insulation inner plug 5.

[0039] In this thermos cup, the thermal insulation inner plug 5 is an integral component integrally formed of silicone or plastic material. The plug body 51 includes an upper plug portion 511, a transition portion 512 and a lower plug portion 513 connected in sequence along the up and down directions. The outer diameter of the upper plug portion 511 is larger than the outer diameter of the lower plug portion 513, and the outer diameter of the transition portion 512 gradually decreases from top to bottom; accordingly, the cup mouth portion 12 has a first mouth portion 121, a second mouth portion 122 and a third mouth portion 123 connected in sequence along the up and down directions. When the plug body 51 is embedded in the cup mouth portion 12, the upper plug portion 511, the transition portion 512 and the lower plug portion 513 correspondingly cooperate with the first mouth portion 121, the second mouth portion 122 and the third mouth portion 123, which enables the outer peripheral wall of the plug body 51 to be fully and tightly attached to the inner peripheral wall of the cup mouth portion 12, so that liquid is not easy to leak from between the two and heat is prevented from dissipating outward from here. At the same time, it is also convenient to embed the plug body 51 into the cup mouth portion 12. In the specific setting, the cup body 1 can be a heat-insulating cup body made of stainless steel.

[0040] The upper portion of the plug body 51 also has a concave groove, the bottom of which is a flat surface 56. The connector 52 protrudes upward from the flat surface 56. During assembly, the connecting portion 43 of the nozzle 4 is sleeved on the connector 52. The flat surface 56 provides a limit for the downward movement of the connecting portion 43 to prevent misalignment during assembly.

[0041] The cover 41 of the nozzle 4 is provided with a ventilation hole (not shown in the figure). A closed chamber is formed between the nozzle 4, the plug body 51, and the cup body 1. The ventilation hole communicates with the exhaust hole 54 on the thermal insulation inner plug 5 through the closed chamber, thereby maintaining a stable air pressure inside and outside the cup body 1. The presence of the above-mentioned closed chamber also allows heat dissipated from the thermal insulation inner plug 5 to transfer through the closed chamber, preventing the thermal insulation inner plug 5 from directly contacting the nozzle 4 and dissipating heat outward, further improving the thermal insulation effect.

[0042] On the thermal insulation inner plug 5, the exhaust hole 54 includes an upper hole portion 541 and a lower hole portion 542 which are connected to each other in the up and down directions. The upper hole portion 541 and the lower hole portion 542 both extend in the vertical direction, and the aperture of the upper hole portion 541 is smaller than the aperture of the lower hole portion 542. This not only facilitates the smooth discharge of gas inside the cup body 1, but also avoids liquid leakage from the exhaust hole 54 when the cup body 1 is tilted or inverted.

[0043] In the thermos cup, the nozzle 4 is an integral component formed of a silicone material. The nozzle 4 can be specifically as follows: Figures 1 to 3 ,as well as Figure 9The nozzle shown in the figure has a tubular mouth 42, which can be used by children over 6 months old; the nozzle 4 can also be Figures 6 to 8 The mouthpiece shown in the figure has a pacifier-shaped mouthpiece 42 that can be used by children over 0 months old.

[0044] In the thermos cup, the straw 6 can be Figures 1 to 3 ,as well as Figure 6 The straw shown in FIG includes a connector 61, a hollow hose 62 and a gravity ball 63. The hollow hose 62 is detachably connected between the connector 61 and the gravity ball 63, and the connector 61 is detachably connected to the connection hole 55. The straw 6 can also be as follows: Figures 8 and 9 The straight tube 64 shown in the figure has a hollow lumen, and the upper portion of the straight tube 64 is detachably inserted into the connecting hole 55 with an interference fit.

[0045] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the essence of the present invention are intended to be included in the scope of protection of the present invention.
