Description
Technical Field
[0001] The utility model relates to the technical field of inner liner of a water bottle, and in particular to an inner liner structure and a water bottle having the same. Background Art
[0002] In the prior art, the inner liner structure of the water bottle generally includes an inner liner body and an inner liner bottom arranged at the bottom of the inner liner body. The inner liner body and the inner liner bottom are generally fixed in two connection methods. One is to weld the bottom edge of the inner liner body and the top edge of the inner liner bottom together. This connection method has extremely strict process requirements, cumbersome procedures and high costs. The other connection method, such as Figure 1-2 As shown, a curling edge is provided at the edge of the inner liner bottom, and then the inner liner body is integrally sleeved on the outside of the inner liner bottom and the bottom of the inner liner body is welded or bonded to the curling edge to achieve connection and fixation. However, when the second connection method is adopted, since the inner liner body is sleeved on the outside of the inner liner bottom, a large gap will be formed between the R angle of the inner liner bottom and the inside of the inner liner body, which not only reduces the overall aesthetics of the inner liner, but also makes it easy for external foreign matter and impurities to enter the gap, thereby causing pollution to the water in the inner liner; furthermore, due to the existence of the gap, users are also likely to touch the gap during cleaning, resulting in a bad touch.
[0003] In order to solve the above problems, it is urgently necessary to provide a new liner structure, which aims to optimize the connection process, reduce costs, and ensure aesthetics and user experience. Utility Model Content

[0011] Furthermore, the outer diameter of the bottom of the inner liner body is smaller than the inner diameter of the inner liner bottom, so that when the bottom of the inner liner body is inserted into the inner liner bottom, a clearance fit is formed between the two.
[0012] Furthermore, when a clearance fit is formed between the bottom of the inner liner body and the inner liner bottom, a horizontal distance between the outer wall of the inner liner body and the inner wall of the inner liner bottom is L, and satisfies: 0.1 mm ≤ L ≤ 0.5 mm.
[0013] Furthermore, the edge of the inner liner bottom is bent outward to form a first inclined bending edge, the first bending edge is bent upward to form a second vertical bending edge, and the first bending edge and the second bending edge together form the flange.
[0014] Furthermore, there are rounded transitions between the first bending edge and the edge of the inner liner bottom, and between the second bending edge and the first bending edge.
[0015] Furthermore, the top of the second bending edge is bent outward to form a third bending edge in a horizontal shape, and there is a rounded transition between the third bending edge and the second bending edge.
[0016] Furthermore, the inner liner body and the inner liner bottom are both made of stainless steel.

[0028] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the modules or components referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0031] like Figure 3-6 An inner liner structure shown includes an inner liner body 1 and an inner liner bottom 2, wherein the inner liner body 1 is cylindrical; the inner liner bottom 2 is disc-shaped; the bottom of the inner liner body 1 is inserted into the inner liner bottom 2; wherein the edge of the inner liner bottom 2 is bent outward to form a flange 21, and the flange 21 and the outer side wall of the inner liner body 1 form an annular glue groove 22, and the glue groove 22 is filled with a colloid to bond and fix the inner liner body 1 and the inner liner bottom 2 together.
[0032] Based on the above structure, in the kettle liner structure of the present invention, the bottom of the liner body 1 is inserted into the interior of the liner bottom 2, and the flange 21 formed by the outer bending of the edge of the liner bottom 2 is filled with colloid to bond and fix the liner body 1 and the liner bottom 2 together. Therefore, the above assembly method not only has low processing requirements for the liner bottom 2, but also simplifies the assembly process, thereby reducing the manufacturing and assembly process requirements; in addition, during the use of the product, the user cannot see the gap between the liner body 1 from the inside, thereby improving the overall aesthetics of the liner, while also avoiding the entry of foreign matter and poor touch.
[0033] It should be noted that, in this embodiment, the colloid used has a certain viscosity to avoid penetration caused by the colloid being too thin. At the same time, the colloid is also resistant to high temperatures to prevent the water in the inner tank from melting during heating, thereby causing looseness between the inner tank body 1 and the inner tank bottom 2, causing the water in the inner tank to penetrate out of the inner tank.
[0034] Furthermore, the outer diameter of the bottom of the inner liner body is larger than the inner diameter of the inner liner bottom 2, so that when the bottom of the inner liner body 1 is inserted into the inner liner bottom 2, an interference fit is formed between the two to tightly connect the inner liner body 1 and the inner liner bottom 2.
[0035] See also Figure 4 The outer diameter of the bottom of the inner liner body 1 is smaller than the inner diameter of the inner liner bottom 2, so that when the bottom of the inner liner body 1 is inserted into the inner liner bottom 2, a clearance fit is formed between the two.
[0036] Specifically, when a gap is formed between the bottom of the inner liner body 1 and the inner liner bottom 2, the horizontal distance between the outer wall of the inner liner body 1 and the inner wall of the inner liner bottom 2 is L, and satisfies: 0.1mm≤L≤0.5mm. Thus, the processing technology requirements of the inner liner bottom 2 of the inner liner body 1 can be reduced, thereby reducing production costs. At the same time, since 0.1mm≤L≤0.5mm, the colloid is prevented from flowing into the inner liner when the colloid is filled in the glue groove 22.
[0037] See also Figure 3 The edge of the inner liner bottom 2 is bent outward to form an inclined first bending edge 211, and the first bending edge 211 is bent upward to form a vertical second bending edge 212. The first bending edge 211 and the second bending edge 212 together form a flange 21.
[0038] Furthermore, there are rounded transitions between the first bending edge 211 and the edge of the inner liner bottom 2 , and between the second bending edge 212 and the first bending edge 211 .
[0039] Specifically, a rounded transition is provided between the first bending edge 211 and the edge of the inner liner bottom 2, so as to guide the insertion of the inner liner body 1 and prevent the inner liner body 1 from scratching the inner wall of the inner liner bottom 2 when inserted into the inner liner bottom 2. A rounded transition is provided between the second bending edge 212 and the first bending edge 211 to prevent the inner liner bottom 2 from being scratched when the user takes it. At the same time, a rounded transition is provided between the first bending edge 211 and the edge of the inner liner bottom 2 and between the second bending edge 212 and the first bending edge 211 to prevent stress concentration from being generated when a right angle is used for transition, thereby affecting the service life of the flange.
[0040] Furthermore, the top of the second bending edge 212 is bent outward to form a third bending edge 213 in a horizontal shape, and a rounded transition is formed between the third bending edge 213 and the second bending edge 212 .
[0041] It should be noted that, in this embodiment, the third bending edge 213 is used to prevent the second bending edge 212 from cutting or generating burrs during the processing when the liner bottom 2 is taken, thereby endangering the operator. Secondly, the third bending edge 213 can also improve the overall strength of the flange 21, making the structure between the flange 21 and the liner bottom 2 more stable. At the same time, the rounded transition between the third bending edge 213 and the second bending edge 212 can also avoid the stress concentration caused by the right angle transition between the third bending edge 213 and the second bending edge 212. Of course, the rounded transition between the third bending edge 213 and the second bending edge 212 can further improve the guiding effect of the bottom of the liner body 1 inserted into the liner bottom 2, avoiding the bottom of the liner body 1 and the liner bottom 2 from being bumped and scratched during the assembly process, thereby affecting the aesthetics of the liner, and in severe cases, it may also cause damage to the liner body 1 and / or the liner bottom 2.
[0042] Furthermore, the inner liner body 1 and the inner liner bottom 2 are both made of stainless steel.
[0043] See also Figure 6 The bottom of the inner tank bottom 2 is provided with a downward and stepped water guide portion, which includes a circular first water guide groove 23 and a second water guide groove 24, and the second water guide groove 24 is located at the center of the first water guide groove 23; a water hole 25 is opened in the center of the second water guide groove 24.
[0044] Specifically, the stepped water guide portion formed by the first water guide groove 23 and the second water guide groove 24 of the inner pot bottom 2 facilitates the water in the inner pot bottom 2 to flow into the water hole 25, thereby preventing water from being retained in the inner pot bottom 2 of the kettle to form scale.
[0045] A water bottle comprises the above-mentioned inner liner structure.
[0046] To sum up, in the inner liner structure of the utility model and the water bottle having the same, the bottom of the inner liner body 1 is inserted into the interior of the inner liner bottom 2, and the flange 21 formed by bending the edge of the inner liner bottom 2 outward is filled with colloid to bond and fix the inner liner body 1 to the inner liner bottom 2. Therefore, the above-mentioned assembly method not only has lower processing requirements for the inner liner bottom 2, but also simplifies the assembly process, thereby reducing the manufacturing and assembly process requirements; in addition, during the use of the product, the user cannot see the gap between the inner liner body 1 from the inside of the inner liner body 1, thereby improving the overall aesthetics of the inner liner, while also avoiding the entry of foreign matter and poor touch.
