Description

Technical Field

[0001] This utility model relates to the technical field, specifically an explosion-proof thermos bottle. Background Technology

[0002] The thermos flask is mainly composed of a double-walled glass liner with a vacuum between the two layers, and is plated with silver or aluminum. The outer shell of the thermos flask is made of materials such as bamboo weaving, plastic, sheet metal, aluminum, and stainless steel. There is a rubber gasket at the mouth of the bottle and a bowl-shaped rubber pad at the bottom. These are all for fixing the glass liner to prevent it from colliding with the outer shell and avoiding violent impacts or drops that could damage the inner liner or the outer shell.

[0003] A heat-insulating and highly sealed thermos bottle disclosed in patent publication number CN220572043U includes an external thread and a sealing ring. The lower end of the cap has an external thread that matches a first thread groove. First, the cap is rotated to remove it, then the stopper is pulled out, liquid is injected, and then the stopper is put back in. The lower half of the stopper has a sealing ring made of elastic material to ensure the sealing of the inner bottle. When the cap is twisted until the lower end contacts the bottle mouth, the pressure block can press the stopper tightly, making it fit tightly with the fixing tube, further improving the overall sealing performance and preventing leakage during carrying. The inner bottle has a vacuum cavity. The outer shell and bottom cover are made of heat-insulating material to ensure the overall heat insulation effect. The bottom cover has an anti-slip pad made of rubber to prevent slipping. The outer shell has hooks on the front and back sides near the top, and a handle is provided between the hooks.

[0004] In daily use, the bottom cover of the above-mentioned device is prone to falling off when moved, causing the inner bottle to fall out and the inner liner inside to explode. It is also difficult to remove and may cause injury to the user. In order to address the above problems, an explosion-proof thermos bottle is proposed. Utility Model Content

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 In this embodiment, an explosion-proof thermos bottle includes a bottle body 1. The bottom of the bottle body 1 is connected to a bottom cover 5 via a connector. A fixing ring 4 is fixedly connected to the surface of the bottom of the bottle body 1. A support ring 6 is slidably connected to the bottom cover 5. A limiting member is provided on the bottom cover 5 to limit the sliding of the support ring 6. The top of the support ring 6 has not less than four sets of connecting holes 14. A fixing block 2 12 is fixedly connected in the connecting holes 14. The fixing ring 4 has a positioning hole 8 corresponding to the connecting hole 14. A bolt 9 is snapped into the positioning hole 8. The bolt 9 is threadedly connected to the fixing block 2 12.

[0026] The bottle body 1 is provided with a thermos liner 17, and the bottom cover 5 is provided with a fixing component for fixing the thermos liner 17. First, use an external tool to remove the bolt 9, pull the support ring 6 downward so that the support ring 6 slides downward on the bottom cover 5, and the connector loses connection. Place the thermos liner 17 into the bottle body 1, and the fixing component fixes the thermos liner 17. Then rotate the bottom cover 5 upward, and the connector connects the bottom cover 5 and the bottle body 1. Then move the support ring 6 upward, and the limiting component limits the support ring 6. Insert the bolt 9 into the positioning hole 8 and insert it into the fixing block 12. Use an external tool to tighten the bolt 9 to complete the installation of the thermos liner 17.

[0027] The connector includes a connecting ring 7 and a connecting groove 11. The bottom of the bottle body 1 is fixedly connected to the connecting ring 7, and the top of the bottom cover 5 is provided with a connecting groove 11 for threaded connection with the connecting ring 7. By rotating the bottom cover 5, the connecting ring 7 is disengaged from the connecting groove 11, and the bottle body 1 and the bottom cover 5 can be connected.

[0028] The limiting component includes a positioning ring 13 and a positioning groove 15. The positioning ring 13 is fixedly connected to the top surface of the bottom cover 5. The top of the support ring 6 is provided with a positioning groove 15 for the positioning ring 13 to be inserted. Moving the support ring 6 upward so that the positioning ring 13 is inserted into the positioning groove 15 can limit the sliding of the support ring 6 and facilitate the sliding of the support ring 6 to be close to the fixed ring 4.

[0029] The fixing components include a fixing block 10 and an anti-collision pad 16. The anti-collision pad 16 is fixedly connected to the top of the inner wall of the bottle body 1. The inner wall of the anti-collision pad 16 is in contact with the surface of the top of the thermos flask inner liner 17. The fixing block 10 is fixedly connected to the bottom of the inner wall of the bottom cover 5. The inner wall of the fixing block 10 is in contact with the bottom of the thermos flask inner liner 17. Rubber pads are provided on the contact side of the anti-collision pad 16 and the fixing block 10. The thermos flask inner liner 17 is placed into the bottle body 1, so that the mouth of the thermos flask inner liner 17 is aligned with the mouth of the bottle body 1, and it is inserted into the anti-collision pad 16. Then, the bottom cover 5 is rotated upward so that the bottom of the thermos flask inner liner 17 contacts the fixing block 10, thereby fixing the thermos flask inner liner 17 and reducing the risk of breakage due to impact. The anti-collision pad 16 and the fixing block 10 are made of PVC foam.

[0030] The bottle body 1 has a stopper 18 at its mouth. The rubber pad at the bottom of the stopper 18 contacts the inner wall of the bottle mouth of the thermos liner 17. The top surface of the bottle body 1 is fitted with a thermos cover 19 and a bottle cap 2. The thermos cover 19 is located inside the bottle cap 2. By setting the thermos cover 19, the hot water in the thermos liner 17 can be further kept warm, and the thermos cover 19 can be used as a cup to hold hot water.

[0031] A handle 3 is provided on one side of the bottle body 1, which allows users to easily pour out the hot water from the inner liner 17 of the thermos.

[0032] The working principle of this utility model is as follows: In use, firstly, use an external tool to remove the bolt 9, pull the support ring 6 downward so that the support ring 6 slides downward on the bottom cover 5, rotate the bottom cover 5 so that the connecting ring 7 disengages from the connecting groove 11, put the thermos flask inner liner 17 into the bottle body 1, align the bottle mouth of the thermos flask inner liner 17 with the bottle mouth of the bottle body 1, and insert it into the anti-collision pad 16. Then rotate the bottom cover 5 upward so that the connecting ring 7 is threaded into the connecting groove 11, so that the bottom of the thermos flask inner liner 17 contacts the fixing block 10 to fix the thermos flask inner liner 17. Then move the support ring 6 upward so that the positioning ring 13 is inserted into the positioning groove 15, and the support ring 6 is close to the fixing ring 4. Insert the bolt 9 into the positioning hole 8 and insert it into the fixing block 12. Use an external tool to tighten the bolt 9 to complete the installation of the thermos flask inner liner 17, reducing the possibility of the thermos flask inner liner 17 exploding due to the bottom cover 5 falling off.
