[0034] Thermos flasks are commonly used to hold and keep warm water. A typical thermos flask consists of a body and a lid. The spout is located on the top side of the body, and the lid is placed over the top side of the body, with the spout inside the lid. When pouring water from a thermos flask, the lid is usually removed, and the water is poured out through the spout. After pouring, the lid is placed on the body. When placing the lid on the body, it is usually necessary to carefully align the lid with the body before installing it. In practice, however, this is often done casually, without careful alignment. This increases the gap between the lid and body, reducing the thermos flask's heat retention effect.

[0035] This utility model proposes a thermos.

[0036] Please see Figure 1 , Figure 2 and Figure 3 In one embodiment of this utility model, the thermos includes:

[0037] The body of the pot, including the spout;

[0038] The lid 2 is placed over the mouth of the pot body 1;

[0039] A first magnetic attraction part is provided on the side wall of the lid 2 and near the mouth of the pot, and is arranged circumferentially around the lid 2; and,

[0040] The second magnetic attraction part is arranged circumferentially around the spout of the kettle body 1. When the lid 2 is placed on the kettle body 1, the first magnetic attraction part and the second magnetic attraction part attract each other.

[0041] The technical solution of this utility model, by setting the first magnetic attraction part and the second magnetic attraction part, allows the first magnetic attraction part and the second magnetic attraction part to attract each other when the lid 2 is installed on the body 1, so that the lid 2 and the body 1 are automatically aligned and the lid 2 is attracted to the body 1. Through the automatic alignment of the lid 2 and the body 1, the correct installation of the lid 2 is ensured, the gap between the lid 2 and the body 1 is reduced, the sealing effect of the lid 2 on the mouth of the body 1 is ensured, and the overall heat preservation effect of the thermos is improved.

[0042] One of the first magnetic attraction part and the second magnetic attraction part is a magnet, and the other is a magnetic metal component. This ensures the attraction effect between the first magnetic attraction part and the second magnetic attraction part. The ferromagnetic structural component is preferably made of metals or alloys such as iron, cobalt, and nickel.

[0043] When the first magnetic attraction part is a magnet, the second magnetic attraction part is a ferromagnetic structural component; when the second magnetic attraction part is a magnet, the first magnetic attraction part is a ferromagnetic structural component.

[0044] Both the first and second magnetic attraction parts are magnets. The first magnetic attraction part is a permanent magnet or a magnetizable structure. The second magnetic attraction part is a permanent magnet or a magnetizable structure. A magnetizable structure includes an electromagnet.

[0045] When the lid 2 is closed on the body 1, the magnetic poles of the first magnetic member 3 and the second magnetic member 4 on their closest sides are different. Both the first magnetic member 3 and the second magnetic member 4 are magnets, which can increase the attraction force between them.

[0046] Both the first magnetic attraction part and the second magnetic attraction part can be ring magnets, and the first magnetic attraction part is sleeved on the lid 2, while the second magnetic attraction part is sleeved on the spout.

[0047] The first magnetic attraction part includes a plurality of first magnetic attraction elements 3, and the second magnetic attraction part includes a plurality of second magnetic attraction elements 4. When the lid 2 is placed on the body 1, the second magnetic attraction elements 4 and the first magnetic attraction elements 3 attract each other.

[0048] Specifically, multiple first magnetic components 3 are arranged sequentially around the lid 2, and multiple second magnetic components 4 are arranged sequentially around the body 1. The magnetic poles on the same side of the multiple first magnetic components 3 are identical, and the magnetic poles on the same side of the multiple second magnetic components 4 are identical. Specifically, the number of first magnetic components 3 and second magnetic components 4 is the same.

[0049] When the lid 2 is placed on the body 1, it can make the force on the circumference of the lid 2 relatively balanced, reducing the offset of the lid 2 to one side.

[0050] Both the first magnetic attractor 3 and the second magnetic attractor 4 are magnets. When the lid 2 is placed on the body 1, the end of each first magnetic attractor 3 near the second magnetic attractor 4 is a first magnetic pole; the end of each second magnetic attractor 4 near the first magnetic attractor 3 is a third magnetic pole, and the first and third magnetic poles are opposite.

[0051] When the lid 2 is placed on the body 1, the first magnetic component 3 is positioned above the second magnetic component 4, and the projection of the first magnetic component 3 relative to the second magnetic component 4 at least partially falls on the second magnetic component 4. This ensures mutual attraction between the first magnetic component 3 and the second magnetic component 4.

[0052] Specifically, the inner diameter of the first magnetic attraction part is greater than the inner diameter of the second magnetic attraction part, and the outer diameter of the first magnetic attraction part is less than or equal to the outer diameter of the second magnetic attraction part.

[0053] Please see Figure 1 , Figure 4 and Figure 5 Preferably, the first magnetic attractor has a first magnetic pole and a third magnetic pole, the first magnetic pole being located on the outer periphery of the first magnetic attractor and the third magnetic pole being located on the inner periphery of the first magnetic attractor. The second magnetic attractor has a second magnetic pole and a fourth magnetic pole, the second magnetic pole being located on the outer periphery of the second magnetic attractor and the fourth magnetic pole being located on the inner periphery of the second magnetic attractor. The first magnetic pole and the second magnetic pole have opposite polarities, and the third magnetic pole and the fourth magnetic pole have opposite polarities.

[0054] During the process of installing the lid onto the body of the kettle, when the lid and the body are misaligned, it is easy for the first magnetic pole of some of the first magnetic components to align with the fourth magnetic pole of the corresponding second magnetic component, and for the second magnetic pole of some of the first magnetic components to align with the third magnetic pole of the corresponding second magnetic component. As the lid continues to fall, the aligned first and fourth magnetic poles repel each other, and the aligned second and third magnetic poles repel each other. At the same time, the first and second magnetic poles attract each other, and the third and fourth magnetic poles align with each other, thus ensuring that the lid and the body are aligned. Overall, automatic alignment between the lid and the body is guaranteed; by ensuring that the lid neatly covers the kettle, the aesthetics of the thermos are preserved.

[0055] Please see Figure 1 , Figure 2 and Figure 3 In order to reduce the exposure of the first magnetic component, a protective cavity is formed in the cover body, and the first magnetic component is located in the protective cavity, which can reduce the exposure of the first magnetic component and reduce the first magnetic component from falling off due to external factors.

[0056] Specifically, the lid includes a first lid body and a second lid body, the second lid body is fitted onto the first lid body, and a protective cavity is formed between the first lid body and the second lid body, and the first magnetic suction member is located inside the protective cavity.

[0057] Please see Figure 2 , Figure 6 and Figure 7 In order to reduce the local closeness between the first cover 21 and the second cover 22 after being subjected to external force, which would cause deformation of the protective cavity 5, support blocks are provided at intervals inside the protective cavity 5. The support blocks are supported between the first cover 21 and the second cover 22 and are bonded to the first cover 21 and the second cover 22. The support blocks can reduce the deformation between the first cover 21 and the second cover 22.

[0058] The side wall of the lid 2 is provided with a mounting cavity 231 extending along the circumferential direction of the lid 2. A plurality of the first magnetic suction members 3 are located in the mounting cavity 231 and arranged sequentially. The mounting cavity 231 reduces the exposure of the first magnetic suction members 3.

[0059] The lid 2 includes a first lid body 21 and a fixing ring 23. The fixing ring 23 is fixedly sleeved on the outside of the first lid body 21, and the fixing ring 23 and the first lid body 21 form the mounting cavity 231.

[0060] The fixing ring 23 is located inside the second cover 22. The fixing ring 23 connects the first cover 21 and the second cover 22, ensuring the gap between the first cover 21 and the second cover 22, and making the mounting cavity located within the protective cavity 5.

[0061] Please see Figure 2 , Figure 6 and Figure 7 When the lid 2 is placed on the body 1, the first magnetic component 3 and the second magnetic component 4 attract each other, causing the lid 2 to be placed on the body 1 more quickly, making it easier for the lid 2 to collide with the body 1.

[0062] The portion of the lid 2 that contacts the body 1 is provided with an elastic part. This elastic part reduces the impact between the lid 2 and the body 1, thus protecting both parts.

[0063] A soft rubber gasket is fitted at the contact point between the kettle body 1 and the kettle lid 2. This soft rubber gasket reduces the impact between the kettle lid 2 and the kettle body 1, thus protecting both parts of the kettle.

[0064] Specifically, the elastic part and the soft rubber gasket can be a rubber sleeve covering the body of the kettle 1.

[0065] In order to protect the second magnetic component 4 and reduce the exposure of the second magnetic component 4, the side wall of the spout is provided with an installation space extending in the circumferential direction of the spout, and a plurality of the second magnetic components 4 are located in the installation space and arranged in sequence.

[0066] The kettle body 1 also includes an inner liner 12 and a bottom cover 13. The inner liner 12 is installed inside the shell 11, and the bottom cover 13 is connected to the bottom of the shell 11. A first mounting ring 6 and a second mounting ring 7 are provided inside the kettle body 1. Both the first mounting ring 6 and the second mounting ring 7 are coaxially arranged with the inner liner 12 and are located outside the inner liner 12. The second mounting ring 7 is located on the bottom side of the first mounting ring 6, and a first mounting groove 61 is provided at the bottom of the first mounting ring 6. The first mounting groove 61 forms the mounting space, and the second magnetic member 4 is located within the first mounting groove 61. The second mounting rings 7 are fixedly connected to each other, thus achieving the fixed installation of the second magnetic member 4. Specifically, multiple second magnetic members 4 abut against each other in sequence.

[0067] Please see Figure 2 , Figure 6 and Figure 7A sealing ring 8 is provided at the mouth of the kettle body 1. The sealing ring 8 can be a rubber ring. The sealing ring 8 connects the inner liner 12 and the shell 11, reducing the gap between the inner liner 12 and the shell 11 and ensuring the heat preservation effect of the thermos.

[0068] A handle is also installed on the outside of the housing 11 to facilitate picking up the thermos.

[0069] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
