[0039] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0040] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the referred module or component must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present utility model.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0042] Referring to Figures 1-9 , the present utility model provides a thermos bottle for preventing the housing from aging and failing, which includes an inner container 2, a housing 1 arranged on the outer periphery of the top of the inner container 2, and a decorative ring 3 arranged on the housing 1. Among them, the inner container 2 is made of stainless steel; the top of the inner container 2 is turned outward to form a first flanging 21; an opening 11 and a groove 12 communicating with the opening 11 are formed on the housing 1. The inner container 2 sequentially passes through the groove 12 and the opening 11 from top to bottom and is hung on the opening 11 through the first flanging 21; the decorative ring 3 is made of stainless steel, and a part of the decorative ring 3 extends into the groove 12 and is engaged with the first flanging 21; thus, the high-temperature water vapor generated by the inner container 2 can sequentially flow along the inner wall of the inner container 2 and the inner wall of the decorative ring 3 and be discharged.

[0043] Therefore, by using the thermos bottle of the present application, by arranging the decorative ring 3 on the housing 1 and the decorative ring 3 being engaged with the first flanging 21 of the inner container 2, when water vapor leaks, the water vapor can sequentially flow along the inner wall of the inner container 2 and the inner wall of the decorative ring 3 and be discharged, thereby avoiding the high-temperature water vapor from contacting the housing 1 and causing the housing 1 to age and fail, and thus extending the service life of the housing 1. In addition, by separately arranging the decorative ring 3 and the inner container 2, the processing technology and assembly difficulty are reduced, and thus the cost is reduced.

[0044] It should be noted that in other embodiments, the decorative ring 3 and the inner container 2 can also be integrally formed, and it can also achieve the effect of preventing the housing 1 from contacting high-temperature water vapor, and there is no limitation here.

[0045] Specifically, the decorative ring 3 includes a first top wall 31 and a first side wall 32 disposed below one side of the first top wall 31 and extending into the groove 12. The bottom of the first side wall 32 is turned inward to form a second flanging 33, and the second flanging 33 is engaged and cooperated with the first flanging 21. Preferably, the first flanging 21 is stacked on the top of the second flanging 33 to achieve the engagement and cooperation.

[0046] Further, the decorative ring 3 further includes a second side wall 34 disposed on the other side of the first top wall 31. A clamping groove 13 is also formed on the housing 1 and surrounds the outside of the groove 12. The first top wall 31 abuts against the housing 1 and the second side wall 34 extends into the clamping groove 13. In this way, not only can the decorative ring 3 be limited and fixed, but also the decorative ring 3 can wrap the outer periphery of the top of the groove 12, thereby further preventing high-temperature water vapor from contacting the housing 1.

[0047] Refer to Figure 5 also includes a sealing ring 4 disposed in the groove 12 and at the opening 11. The second flanging 33 abuts against the top of the sealing ring 4, and the first flanging 21 is stacked on the top of the second flanging 33 and presses and fixes the second flanging 33 and the sealing ring 4. Thus, by providing the sealing ring 4, the inner container 2 and the opening 11 of the housing 1 can be sealed to prevent water vapor leakage.

[0048] In this embodiment, the first top wall 31, the first side wall 32 and the second side wall 34 in the decorative ring 3 are integrally formed.

[0049] Refer to Figures 6-9 also includes a kettle lid 5 covering the top of the inner container 2. The kettle lid 5 includes an outer lid 51. The outer lid 51 is made of stainless steel and includes a second top wall 511 and a side wall 512 surrounding the lower part of the outer periphery of the second top wall 511. When the kettle lid 5 covers the top of the inner container 2, the side wall 512 and the inner wall of the inner container 2 and the inner wall of the decorative ring 3 enclose a steam channel for discharging water vapor. Specifically, the side wall 512 includes a third side wall 5121 protruding outward and a fourth side wall 5122 connected to the third side wall 5121 and extending downward. When the kettle lid 5 covers the top of the inner container 2, the third side wall 5121 abuts against the top of the first flanging 21, and the fourth side wall 5122 extends into the inner container 2.

[0050] Thus, by making the outer lid 51 of stainless steel, there is no need to provide a silicone ring between the outer lid 51 and the inner container 2 for sealing. The kettle lid 5 will not produce any plastic smell such as silicone during use, thereby improving the user experience; in addition, since there is no silicone ring, it is possible to avoid the water in the inner container 2 contacting the silicone ring and generating an odor, thus ensuring the cleanliness and hygiene of the water in the inner container 2.

[0051] Further, a number of bumps 51221 are provided on the fourth sidewall 5122 in a ring shape. When the outer lid 51 is covered on the inner container 2, the bumps 51221 are in contact with the inner sidewall of the inner container 2. Thus, by providing the bumps 51221, not only is the outer lid 51 more firmly assembled on the inner container 2, but also a certain frictional force is generated when the user assembles or removes the kettle lid 5, giving it an assembly feel.

[0052] In this embodiment, four bumps 51221 are provided and are arranged at intervals in the circumferential direction on the fourth sidewall 5122; of course, in other embodiments, the number of bumps 51221 can also be set to other quantities (such as 2, 3, or more than 4), and the number of bumps 51221 is not limited here.

[0053] In addition, a number of ventilation holes 5111 are also provided on the second top wall 511 of the outer lid 51. The high-temperature water vapor generated in the inner container 2 can be discharged to the outside through the number of ventilation holes 1111, thereby achieving air pressure balance and further ensuring the safe use of the thermos flask.

[0054] Refer again to Figures 6-9 , and it further includes an inner lid 52 provided in the middle inside the outer lid 51. Specifically, the middle part of the second top wall 511 of the outer lid 51 is concave to form a mounting groove 5112. The inner lid 52 is provided in the mounting groove 5112 and its periphery and bottom are all shielded. A handle 521 is provided on the top of the inner lid 52. Among them, a number of mounting holes 5113 are provided in a ring shape on the mounting groove 5112, and mounting posts 522 corresponding to the mounting holes 5113 are provided in a ring shape on the bottom of the inner lid 52, and screw holes are provided in the mounting posts 522; thus, by passing a bolt through the mounting hole 5113 and threadedly connecting it into the screw hole, the inner lid 52 can be fixed in the mounting groove 5112.

[0055] To sum up, a thermos flask provided by the present utility model for preventing the housing from aging and failing has the following beneficial effects:

[0056] (1) For the thermos flask of the present utility model, by providing the decorative ring 3 on the housing 1 and the decorative ring 3 being engaged and cooperating with the first flanging 21 of the inner container 2, when water vapor leaks, the water vapor can sequentially flow along the inner wall of the inner container 2 and the inner wall of the decorative ring 3 and be discharged, thereby preventing the high-temperature water vapor from contacting the housing 1 and causing the housing 1 to age and fail, and thus extending the service life of the housing 1.

[0057] (2) For the thermos flask of the present utility model, by separately providing the decorative ring 3 and the inner container 2, the processing technology and assembly difficulty are reduced, and thus the cost is reduced.
