DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0031] Embodiment one:

[0032] As shown in the drawings, Figures 1 to 7 The present application provides a self-heating storage device, which comprises a first shell 1, a second shell 3, a cover 5 and a cup 7. The first shell 1 can be a metal can. The top of the first shell 1 has an openable end cover 2. The edge of the end cover 2 is connected to the first shell 1 by a crimping process. The end cover 2 can adopt a pull ring type opening structure similar to a pop can. The second shell 3 is embedded in the first shell 1 (i.e. the second shell 3 is inserted into the first shell 1 from the bottom of the first shell 1). The cover 5 is arranged at the bottom of the second shell 3 and the first shell 1. As shown in the drawings, Figure 1 and Figure 2 The edge of the bottom of the first shell 1, the edge of the bottom of the second shell 3 and the edge of the cover 5 are connected by a double crimping process, so that the first shell 1, the end cover 2 and the second shell 3 cooperate to form a sealed first inner cavity 4. The first inner cavity 4 can store liquid or solid-liquid mixture, such as traditional Chinese medicine decoction and eight-treasure rice pudding. The cover 5 cooperates with the second shell 3 to form a second inner cavity 6.

[0033] As shown in the drawings, Figure 1As shown, the top of the second shell 3 is provided with a reverse recess 10 recessed to the second inner cavity 6. By providing the reverse recess 10, a part of the stored object in the first inner cavity 4 can be in the reverse recess 10, so as to increase the capacity of the first inner cavity 4 and increase the contact area of the stored object with the second shell 3. The inner wall of the second shell 3 is provided with a stepped first boss 23. The cup body 7 is arranged in the second inner cavity 6, and the end of the cup body 7 close to the reverse recess 10 is closed by the sealing film 8 and abuts against the first boss 23. In this way, the cup body 7 also has a sealed space inside, and the reaction liquid such as clean water or other water-containing reagents can be stored in the cup body 7. Then, the reaction agent capable of generating exothermic reaction with the reaction liquid, such as quicklime, is placed in the second inner cavity 6 between the sealing film 8 and the reverse recess 10. The cup body 7 is also provided with a top piercing member 9, and the bottom of the cup body 7 and the cover 5 are both provided with an outer convex surface 11. The cup body 7 and the cover 5 can both be deformed. The cup body 7 is made of plastic, and the cover 5 can be made of aluminum.

[0034] When the outer convex surface 11 of the cover 5 is pressed, the outer convex surface 11 is deformed inwardly under force and presses the bottom of the cup body 7. Since the top of the cup body 7 abuts against the first boss 23, the bottom of the cup body 7 will also be deformed and press the top piercing member 9 inside. The top piercing member 9 is pushed and moves upwardly and pierces the sealing film 8, so that the reaction liquid in the cup body 7 is no longer in a sealed state. By inverting and shaking the first shell 1, the reaction liquid in the cup body 7 can be brought into contact with the reaction agent and generate exothermic reaction. The heat generated is transmitted to the stored object in the first inner cavity 4 through the second shell 3, so as to heat the stored object.

[0035] If the stored object is traditional Chinese medicine soup, the traditional Chinese medicine soup is heated to a warm state from room temperature, which is more suitable for users to drink.

[0036] In some possible implementation manners, the first shell 1 can be a bottle body made of glass instead of a metal can. The end cover 2 can be a plastic cover threadedly matched with the first shell 1.

[0037] Embodiment two:

[0038] On the basis of the embodiment one, the present application further proposes the specific design of the cup body 7 and the top piercing member 9. As shown, Figure 5 The inner wall of the cup body 7 of the present application is provided with a limiting flange 14, and the bottom of the inner cavity of the cup body 7 is provided with a positioning plug 15. The limiting flange 14, the positioning plug 15 and the cup body 7 can be integrally formed by plastic material. Figure 6 and Figure 7The top piercing member 9 of the present application comprises a circular truncated cone shaped frame 16, four bayonets 18 evenly distributed on the top edge of the frame 16, and four limiting blocks 19 fixed on the bayonets 18. A plurality of through holes 20 are evenly distributed on the frame 16, and a plug hole 17 is formed on the bottom center of the frame 16 to cooperate with the positioning plug 15. Thus, the top piercing member 9 can be fixed in the cup body 7 by the interference fit between the positioning plug 15 and the plug hole 17, and the limiting blocks 19 are abutted against the limiting flange 14 to further limit the top piercing member 9.

[0039] The through holes 20 can reduce the weight and material of the frame 16, and the water in the cup body 7 can easily pass through the through holes 20. In order to strengthen the structural strength of the frame 16, four inner ribs 21 and four outer ribs 22 are respectively fixed on the inner wall and the outer wall of the frame 16. The top piercing member 9 of the present application can also be integrally formed by using plastic material.

[0040] When the cover 5 is pressed, the cup body 7 is deformed under stress, so that the frame 16 in the cup body 7 moves upward, and the bayonets 18 at the top pierce the sealing film 8.

[0041] Example three:

[0042] On the basis of the above-mentioned examples, the present application forms a gas permeable hole 12 on the outer convex surface 11 of the cover 5. The gas permeable hole 12 allows the gas in the second inner cavity 6 to be discharged, so that when the reaction liquid and the reagent have an exothermic reaction, the hot gas in the second inner cavity 6 can be partially discharged from the gas permeable hole 12 to prevent the pressure in the second inner cavity 6 from being too high. At the same time, the existence of the gas permeable hole 12 also reduces the strength of the outer convex surface 11 of the cover 5, so that the cover 5 is more easily deformed.

[0043] In order to retain the pressure relief capability while avoiding the entry of external water vapor into the second inner cavity 6 from the gas permeable hole 12, the present application fixes a one-way gas permeable film 13 on the side of the cover 5 close to the cup body 7. The one-way gas permeable film 13 allows the water and gas in the second inner cavity 6 to pass through the one-way gas permeable film 13, but can prevent external water and gas from entering the second inner cavity 6, so that the pressure relief capability can be maintained, and the reagent can be prevented from being damp.

[0044] Example four:

[0045] On the basis of the above-mentioned examples, considering that the present application needs to be inverted and shaken sufficiently to allow the reaction liquid and the reagent to be in sufficient contact and reaction. In order to more easily and sufficiently achieve the reaction of the reaction liquid and the reagent, the present application further designs the following structure.

[0046] As Figures 8 to 11As shown, the cup body 7 is provided with a telescopic wavy shape, which can refer to the structure of a bellows. When the bottom of the cup body 7 is subjected to a force, the cup body 7 can be compressed. In order to compress the cup body 7, a compression mechanism is arranged in the second shell 3 for compressing the cup body 7.

[0047] As shown in Figure 8 and Figure 9 The compression mechanism of the present application comprises a limiting sleeve 24 sleeved on the cup body 7, a spring 26 and an arc-shaped plate 27 arranged inside the limiting sleeve 24. The top of the limiting sleeve 24 can abut against the first boss 23, and the other end of the limiting sleeve 24 is symmetrically inserted with a lock block 25 which can slide. One end of the spring 26 is fixed to the end of the limiting sleeve 24 close to the first boss 23, and the other end of the spring 26 can be buckled on the part of the lock block 25 inside the limiting sleeve 24. At this time, the spring 26 is in a stretched state. As shown in Figure 11 The spring 26 can be supported on the bottom of the cup body 7.

[0048] As shown in Figure 8 and Figure 9 The arc-shaped plate 27 is arranged between the cover 5 and the cup body 7, and the two ends of the arc-shaped plate 27 abut against the two lock blocks 25. Meanwhile, a stepped second boss 28 is arranged on the second shell 3. When the cover 5 is pressed, the cover 5 is deformed and presses the arc-shaped plate 27. When the arc-shaped plate 27 is pressed, it tends to be flat, thereby pushing the two lock blocks 25 to move. The lock blocks 25 abut against the second boss 28 and are separated from the spring 26. At this time, the spring 26 is contracted and supports the bottom of the cup body 7, thereby compressing the cup body 7.

[0049] Through the above arrangement, when the cover 5 is pressed, not only the top piercing member 9 can pierce the sealing film 8, but also the spring 26 can compress the cup body 7, so that the reaction liquid in the cup body 7 is extruded upward from the pierced sealing film 8 and fully contacts with the reagent. Meanwhile, since the cup body 7 is compressed, the slurry formed by the fusion reaction of the reagent and the reaction liquid is also supported by the compressed cup body 7 (compared with the first embodiment, if the cup body 7 cannot be compressed, part of the slurry formed by the mixing will enter the cup body 7 from the pierced sealing film 8, which is not conducive to the heat transfer to the second shell 3), thereby fully contacting with the top of the second shell 3 and better conducting heat.

[0050] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies thereof, the present application also intends to include these modifications and variations.
