Description

Technical Field

[0001] The present application relates to the technical field of household products, and in particular to an anti-breakage thermos bottle. Background Art

[0002] A thermos, also known as a hot water bottle or warm water bottle, consists of an outer shell and an inner liner. A thin layer of silver or other reflective paint is coated on the inner liner. This layer of paint can reflect thermal radiation, thereby reducing the loss of heat through radiation. It is an everyday item.

[0003] The existing thermos flask liners usually use glass liners and stainless steel liners. Although the stainless steel liners have good heat preservation effects and can withstand impacts and falls in daily use, the stainless steel liners are heavy. When the stainless steel liners are filled with hot water, it is difficult to lift the water bottle by holding the water bottle handle with one hand. The glass liners also have good heat preservation effects, but they are fragile. The existing patent (Announcement No.: CN218738491U) discloses a thermos flask with an inner liner that is not easy to break. The inner liner wall is cleaned by arranging multiple structures inside the outer shell. At the same time, springs and rubber blocks are arranged to achieve buffer protection for the inner liner, thereby improving the anti-breakage effect. However, the cleaning structure, springs and rubber blocks are arranged inside the outer shell, which will increase the overall weight of the thermos flask. When the thermos flask is full of water, it is difficult to lift the water bottle by holding the water bottle handle with one hand. At the same time, this design cannot replace the inner liner. Utility Model Content

[0004] The purpose of the present application is to provide a breakage-resistant thermos bottle to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a breakage-resistant thermos bottle, comprising an outer shell assembly and an inner liner fixed inside the outer shell assembly, the outer shell assembly comprising an inner shell, a lower seat body integrally formed at the lower end of the inner shell, an upper seat body detachably mounted at the upper end of the inner shell, avoidance grooves provided on opposite sides of the upper seat body and the lower seat body, an outer shell body sleeved on the outside of the inner shell body and fixedly connected to the avoidance groove, and a handle fixedly connected to the outer surface of the inner shell body, passing through the outer shell body and extending outward.

[0006] In one embodiment, a support unit is provided on the inner wall of the inner shell, and the support unit includes an annular sleeve fixedly connected to the inner wall of the inner shell, a plurality of arc seats evenly distributed and fixed on the inner wall of the annular sleeve, screw grooves opened inside the plurality of arc seats, a hollow disk screwed in the screw grooves, and a buffer pad four fixedly connected to one side of the hollow disk, and the outer surface of the buffer pad four is in contact with the outer surface of the lower end of the inner liner.

[0007] In one embodiment, an internal thread 2 matching the screw groove is provided on the inner wall of the arc seat, and a buffer pad 3 is fixedly connected to the inner wall of the arc seat, and one side of the buffer pad 3 is in contact with one side of the arc seat.

[0008] In one embodiment, a buffer collar is sleeved on the outer surface of the upper end of the inner shell, and the outer surface of the buffer collar is in contact with the inner wall of the inner shell.

[0009] In one embodiment, the lower end of the lower seat body is also connected to a bottom support module, and the bottom support module includes a screw connection part 2 integrally formed at the lower end of the lower seat body, a base screwed on the screw connection part 2, a buffer pad 1 sleeved on the outside of the screw connection part 2 and located between the lower seat body and the base, and a buffer pad 2 which is in contact with the lower end of the screw connection part 2 on one side and in contact with the base on the other side.

[0010] In one embodiment, an internal thread one matching with a screw connection part two is provided inside the base, a screw connection part one is provided on the outer surface of the shell, and a cover body is screwed onto the screw connection part one.

[0011] In one embodiment, a water diversion end is integrally formed at the upper end of the upper seat body.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] The present application designs a double-layer shell assembly consisting of an inner shell and an outer shell, and there is a hollow structure between the outer shell and the inner shell. Because the two layers of material can support each other, the overall structural strength is increased. The double-layer structure can provide better impact absorption and dispersion capabilities by adding an extra layer. When the thermos bottle accidentally falls, the double-layer shell can reduce the force of direct impact on the inner liner, thereby reducing the risk of the inner liner breaking. The double-layer structure is stronger than the single-layer structure, thereby improving the thermos bottle's drop resistance and anti-shattering performance. At the same time, the weight of the outer shell is less than the weight of the spring and the rubber block, which not only improves the anti-shattering performance of the thermos bottle but also avoids the situation where the thermos bottle is too heavy.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0026] Example:

[0027] See also Figure 1-9The present application provides a technical solution: an anti-breakage thermos bottle, comprising an outer shell 15 assembly and an inner liner 5 fixed inside the outer shell assembly 1, the outer shell 15 assembly comprises an inner shell 11, a lower seat 12 integrally formed at the lower end of the inner shell 11, an upper seat 13 detachably mounted at the upper end of the inner shell 11, a position avoidance groove 14 provided on opposite sides of the upper seat 13 and the lower seat 12, an outer shell 15 sleeved outside the inner shell 11 and fixed in the position avoidance groove 14, and a handle 4 fixed to the outer surface of the inner shell 11 and penetrating the outer shell 15 and extending outward. A water inlet 16 is integrally formed at the upper end of the upper seat 13.

[0028] The upper seat 13 is screwed to the upper end of the inner shell 11 by screws. This design is to facilitate the outer shell 15 to be put on the outside of the inner shell 11, and the outer shell 15 is clamped by the upper seat 13 and the lower seat 12. The outer shell 15 and the inner shell 11 are both made of plastic. There is a hollow structure between the outer shell 15 and the inner shell 11. The double-layer structure can provide better impact absorption and dispersion capabilities by adding an extra layer. When the thermos bottle accidentally falls, the double-layer outer shell can reduce the force of direct impact on the inner liner, thereby reducing the risk of the inner liner breaking. The double-layer structure is stronger than the single-layer structure, thereby improving the thermos bottle's drop resistance and anti-breakage performance. The water inlet end 16 is used to drain the water discharged from the inner liner 5.

[0029] See also Figure 6-Figure 9 In this embodiment, a support unit 6 is provided on the inner wall of the inner shell 11, and the support unit 6 includes an annular sleeve 61 fixedly connected to the inner wall of the inner shell 11, a plurality of arc seats 62 evenly distributed and fixed on the inner wall of the annular sleeve 61, screw grooves 63 provided inside the plurality of arc seats 62, a hollow disk 64 screwed in the screw grooves 63, and a buffer pad 4 67 fixedly connected to one side of the hollow disk 64, and the outer surface of the buffer pad 4 67 is in contact with the outer surface of the lower end of the inner liner 5. An internal thread 2 65 matching the screw groove 63 is provided on the inner wall of the arc seat 62, and a buffer pad 3 66 is also fixedly connected to the inner wall of the arc seat 62, and one side of the buffer pad 3 66 is in contact with one side of the arc seat 62. A buffer collar 51 is sleeved on the outer surface of the upper end of the inner liner 5, and the outer surface of the buffer collar 51 is in contact with the inner wall of the inner shell 11.

[0030] By screwing the hollow disk 64 into the arc seat 62, the bottom of the inner liner 5 can be positioned and fixed. The outer surface of the upper end of the inner liner 5 is fitted with the upper inner wall of the inner shell 11 through the buffer collar 51, and then the bottom of the inner liner 5 is fixed by the hollow disk 64 to fix the inner liner 5 in the inner shell 11. The buffer collar 51, buffer pad four 67 and buffer pad three 66 can achieve the effect of buffering and shock absorption to avoid the influence of external force on the inner liner 5. At the same time, compared with the existing thermos bottle, a base is provided at the bottom of the shell to support the inner liner 5, and the inner liner 5 is fixed in the shell through the base. However, when the base is subjected to force, the force will be directly applied to the inner liner 5, which may cause the inner liner 5 to break. Therefore, the fixing method of the present application does not need to fix the inner liner 5 through the base, which can improve the anti-breakage performance of the water bottle.

[0031] See also Figure 3-Figure 5 In this embodiment, the lower end of the lower seat body 12 is also connected to a bottom support module 2, and the bottom support module 2 includes a screw connection part 21 integrally formed at the lower end of the lower seat body 12, a base 24 screwed on the screw connection part 21, a buffer pad 22 sleeved outside the screw connection part 21 and located between the lower seat body 12 and the base 24, and a buffer pad 23 with one side attached to the lower end of the screw connection part 21 and the other side attached to the base 24. The base 24 is provided with an internal thread 25 matching the screw connection part 21, and the outer surface of the outer shell 15 is provided with a screw connection part 17, and the cover body 3 is screwed on the screw connection part 17.

[0032] The bottom support module 2 is used to support the entire thermos bottle, so the buffer pad 1 22 and the buffer pad 2 23 can play a role in buffering and shock absorption. At the same time, the bottom support module 2 is not in direct contact with the inner liner 5, so as to avoid the force of the bottom support module 2 directly acting on the inner liner 5 and causing the inner liner 5 to break. The base 24 can be unscrewed from the screw connection part 21, and then the hollow disk 64 can be easily unscrewed from the arc seat 62, so that the inner liner 5 can be quickly replaced.
