Description

Technical Field

[0001] This application relates to the field of heating devices, and in particular to a self-heating device and a self-heating Chinese medicine liquid. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to drugs that are collected, processed, and prepared according to the principles of traditional Chinese medicine, with explained mechanisms of action and guidance for clinical application. TCM generally requires a long decoction process before consumption, but most patients lack the necessary facilities for this process, leading to the emergence of TCM decoction services. These services involve hospitals decocting TCM into a liquid, packaging it in TCM bags, and mailing the bags to patients.

[0003] Most existing instructions for using packaged Chinese medicine liquid clearly state that it needs to be heated twice before use. However, many patients do not have the means to heat the medicine when they need to take it, which makes it inconvenient to heat the packaged Chinese medicine liquid twice. Utility Model Content

[0004] This application primarily addresses the technical problem of inconvenient secondary heating of bagged traditional Chinese medicine liquid in existing technologies. It provides a self-heating device and a self-heating traditional Chinese medicine liquid that integrates the heating element with the bagged traditional Chinese medicine liquid for convenient secondary heating.

[0005] To address the aforementioned technical problems, this application provides a self-heating device, characterized in that the self-heating device comprises,

[0006] An outer casing, wherein the outer casing has a first receiving cavity;

[0007] The self-heating pack is located in the first receiving cavity. The self-heating pack consists of an outer packaging bag and a self-heating agent. The self-heating agent is located inside the outer packaging bag, which is made of a water-permeable material.

[0008] A liquid storage bag is located within the first receiving cavity, and the liquid storage bag contains a self-heating liquid that reacts with the self-heating agent to form a self-heating reaction.

[0009] A disruptive structure is used to disrupt the liquid storage tank so that the self-heating liquid in the liquid storage tank can flow to the self-heating tank to generate heating heat.

[0010] A temperature display, located within the first receiving cavity, is used to detect the temperature within the first receiving cavity;

[0011] The object to be heated is located within the first receiving cavity.

[0012] In one possible embodiment, the self-heating device further includes,

[0013] The system comprises an inner shell and a connecting structure. The inner shell is located within a first receiving cavity, and the inner shell contains a second receiving cavity. The object to be heated is located within the second receiving cavity. A first vent hole is provided at the bottom of the inner shell. The inner shell is detachably connected to an outer shell via the connecting structure. The outer shell and the inner shell can be in a connected state or a separated state.

[0014] In the connected state, the outer shell is connected to the inner shell through the connecting structure, and the relative position of the breaking structure and the liquid storage bag is fixed;

[0015] In the separated state, the outer shell and the inner shell are separated, and the rupture structure is displaced from the liquid storage bag. The rupture structure ruptures the liquid storage bag, and the self-heating liquid in the liquid storage bag flows to the self-heating bag.

[0016] In one possible implementation, the connection structure includes,

[0017] An oil strip, wherein the oil strip is circumferentially arranged around the outer shell and the inner shell, and the oil strip is located between the outer shell and the inner shell;

[0018] Easy-tear strip, the easy-tear strip is connected to the inner shell and / or the outer shell through the easy-tear strip.

[0019] In one possible implementation, the connection structure further includes,

[0020] A pull ring, the first end of which is connected to the Lewis bar, and the second end of which extends outward.

[0021] In one possible embodiment, the inner housing further includes,

[0022] The inner shell has a first opening at its upper end, and the cover film covers the first opening to seal the inner shell.

[0023] In one possible embodiment, the self-heating device further includes,

[0025] In one embodiment, the cover is provided with a second vent hole, and a waterproof and breathable membrane is disposed inside the second vent hole.

[0026] In one possible embodiment, the liquid storage bag includes,

[0027] Self-heating liquid;

[0028] A rigid shell, wherein the rigid shell has a third receiving cavity, and the self-heating liquid is stored in the third receiving cavity;

[0029] A waterproof membrane is attached to the inner surface of the rigid housing.

[0030] In one embodiment, the destructive structure includes a connecting rope, a first end of which is connected to the liquid storage bag, and a second end of which is connected to the inner shell.

[0031] When the outer shell and the inner shell switch from the connected state to the separated state, the inner shell falls inside the outer shell, and at the same time the connecting rope pulls the liquid storage bag to release the self-heating liquid in the liquid storage bag.

[0032] In one embodiment, the bottom of the rigid shell is provided with a third opening, and an easy-tear strip is provided inside the third opening. The easy-tear strip is connected to the rigid shell by an easy-tear groove to close the third opening. The first end of the connecting rope is connected to the easy-tear strip.

[0033] In one embodiment, the rigid shell is made of paper material, and the liquid storage bag is disposed at the bottom of the inner shell;

[0034] The damaged structure includes,

[0035] A horizontal plate assembly is disposed between the liquid storage bag and the self-heating bag. The horizontal plate assembly includes a left horizontal plate and a right horizontal plate that are spaced apart from each other. A water-permeable gap is formed between the left horizontal plate and the right horizontal plate. Both the left horizontal plate and the right horizontal plate are connected to the outer shell.

[0036] The destructive structure also includes,

[0037] A needle is disposed between the liquid storage bag and the self-heating bag. The first end of the needle is connected to the horizontal plate assembly, and the second end of the needle extends toward the liquid storage bag. The second end of the needle is spaced apart from the liquid storage bag.

[0038] Another aspect of this application provides a self-heating traditional Chinese medicine liquid, characterized in that it includes the self-heating device in Example 1 or Example 2, wherein the substance to be heated is a bagged traditional Chinese medicine liquid.

[0039] Compared to existing technologies, the object to be heated is placed directly in the self-heating device, and a self-heating pack and a liquid storage pack are placed inside the outer shell of this application. Then, the liquid storage pack is destroyed by a destructive structure to release the self-heating liquid in the liquid storage pack. When the self-heating liquid comes into contact with the self-heating agent, it will generate heating heat. At the same time, the self-heating liquid boils and heats the object to be heated, so as to achieve rapid heating of the object. The self-heating device is sold together with the object to be heated, so patients can directly heat the object through the self-heating device when they receive it.

[0040] Therefore, this application has the characteristics of reasonable structure and convenient use. Attached Figure Description

[0055] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] The existing technology has the technical problem of inconvenience in reheating bagged Chinese medicine liquid.

[0057] Therefore, this application provides a self-heating device, characterized in that the self-heating device includes,

[0058] An outer casing, wherein the outer casing has a first receiving cavity;

[0059] The self-heating pack is located in the first receiving cavity. The self-heating pack consists of an outer packaging bag and a self-heating agent. The self-heating agent is located inside the outer packaging bag, which is made of a water-permeable material.

[0060] A liquid storage bag is located within the first receiving cavity, and the liquid storage bag contains a self-heating liquid that reacts with the self-heating agent to form a self-heating reaction.

[0061] A disruptive structure is used to disrupt the liquid storage tank so that the self-heating liquid in the liquid storage tank can flow to the self-heating tank to generate heating heat.

[0062] A temperature display, located within the first receiving cavity, is used to detect the temperature within the first receiving cavity;

[0063] The object to be heated is located within the first receiving cavity.

[0064] Another aspect of this application provides a self-heating traditional Chinese medicine liquid, including the self-heating device in Example 1 or Example 2, wherein the substance to be heated is a bagged traditional Chinese medicine liquid.

[0065] Example 1:

[0066] Please refer to the attached document. Figure 1 To be continued Figure 3 As shown, one embodiment of the self-heating device of this application is presented.

[0067] Appendix Figure 1 This is a schematic diagram of one embodiment of the self-heating device of this application. Please refer to the attached diagram. Figure 1 As shown, the self-heating device of this application is used to heat the object 500 to be heated. The self-heating device includes the object 500, which is stored inside and sold together with the device, allowing users to directly heat the object 500 using the self-heating device. In this application, the outer packaging of the object 500 can be in the form of a bag or a box, and the contents of the object 500 can be a solid or a liquid. Furthermore, the object 500 can be boxed milk or bagged traditional Chinese medicine liquid.

[0068] Please refer to the attached document. Figure 1 As shown, the self-heating device of this application includes an outer shell 100, which has a first receiving cavity 110 inside. The upper end of the outer shell 100 is provided with a second opening, which is connected to the first receiving cavity 110. The outer shell 100 is the outermost protective device, used to protect the self-heating pack 200, the liquid storage pack 300 and the damage structure 400, and to store the object to be heated 500 in the first receiving cavity 110 of the outer shell 100 at the same time.

[0069] In one embodiment, the cross-section of the outer casing 100 is circular or rectangular.

[0070] In one embodiment, the outer casing 100 is made of a rigid, waterproof material.

[0071] In one embodiment, an insulating film is provided on the inner surface of the outer casing 100.

[0072] Please refer to the attached document. Figure 1 As shown, the self-heating device of this application includes a self-heating pack 200, which is located within a first receiving cavity 110. Further, the position of the self-heating pack 200 within the first receiving cavity 110 is such that it can contact the self-heating liquid 310 flowing out after the storage pack 300 ruptures. In one embodiment, the self-heating pack 200 is located at the bottom of the first receiving cavity 110.

[0073] In one embodiment, the self-heating pack 200 includes an outer packaging bag and a self-heating agent. The self-heating agent is located inside the outer packaging bag, which is made of non-woven fabric. The main components of the self-heating agent are quicklime, sodium bicarbonate, magnesium sulfate, and other materials. The self-heating agent generates high temperature upon contact with water.

[0074] In one embodiment, the self-heating pack 200 is fixedly connected to the bottom of the first receiving cavity to avoid the self-heating pack 200 impacting the liquid storage pack 300 during transportation.

[0075] Please refer to the attached document. Figure 1As shown, the self-heating device of this application includes a liquid storage tank 300, which is located within a first receiving cavity 110. The liquid storage tank 300 contains a self-heating liquid 310 that reacts with a self-heating agent to form a self-heating reaction; the self-heating agent reacts with the self-heating liquid 310 to generate high temperatures. Furthermore, the liquid storage tank 300 is located at the top of or to one side of the self-heating pack 200, so that in the event of a rupture, the self-heating liquid 310 within the liquid storage tank 300 flows into the self-heating pack 200.

[0076] In one embodiment, the self-heating liquid 310 is water or other aqueous solutions.

[0077] In one embodiment, the liquid storage bag 300 is located between the side wall of the inner shell 600 and the side wall of the outer shell 100, and the liquid storage bag 300 is fixedly connected to the side wall of the outer shell 100.

[0078] Please refer to the attached document. Figure 1 As shown, the self-heating device of this application includes an inner shell 600, which is located within a first receiving cavity 110. The inner shell 600 has a second receiving cavity 610, which is also located within the first receiving cavity 110; that is, the second receiving cavity 610 is a part of the first receiving cavity 110. A first vent hole 620 is provided at the bottom of the inner shell 600 to allow the heat generated after the self-heating agent encounters the self-heating liquid 310 to enter the inner shell 600 through the first vent hole 620.

[0079] In one embodiment, the cross-section of the inner housing 600 is circular or rectangular.

[0080] In one embodiment, the object to be heated 500 is located in the second receiving cavity 610, and the self-heating pack 200 and the liquid storage pack 300 are located in the area outside the second receiving cavity 610 within the first receiving cavity 110.

[0081] In one embodiment, the top of the inner housing 600 is flush with the top of the outer housing 100.

[0082] Please refer to the attached document. Figure 1 As shown, the self-heating device of this application also includes a breaking structure 400, which is used to break the water tank so that the self-heating liquid 310 in the storage tank 300 can flow to the self-heating pack 200 to generate heating heat, which is used to directly heat the object 500 to be heated.

[0083] In this application, the destructive structure 400 includes a connecting rope 410. The first end of the connecting rope 410 is connected to the liquid storage tank 300, and the second end of the connecting rope 410 is connected to the inner shell 600. The connecting rope 410 is fixedly connected to both the liquid storage tank 300 and the inner shell 600. Therefore, the connecting rope 410 will not separate from the liquid storage tank 300 and the inner shell 600 when it moves. However, since the material used for the outer shell of the liquid storage tank 300 is not very strong, the liquid storage tank 300 will be torn under the pull of the connecting rope 410, causing the self-heating liquid 310 inside the liquid storage tank 300 to overflow.

[0084] Please refer to the attached document. Figure 1 As shown, the self-heating device of this application also includes a connecting structure 700. The inner shell 600 is detachably connected to the outer shell 100 through the connecting structure 700. With the inner shell 600 and the outer shell 100 detachably connected, the outer shell 100 and the inner shell 600 are in a connected state and a separated state.

[0085] In the connected state, the outer shell 100 is connected to the inner shell 600 via the connecting structure 700, and the relative position between the breaking structure 400 and the liquid storage tank 300 is fixed, thus ensuring that the breaking structure 400 is unlikely to accidentally break the liquid storage tank 300. In the separated state, the outer shell 100 and the inner shell 600 are separated, and displacement occurs between the breaking structure 400 and the liquid storage tank 300. The breaking structure 400 breaks the liquid storage tank 300, and the self-heating liquid 310 inside the liquid storage tank 300 flows to the self-heating pack 200. Furthermore, when the outer shell 100 and the inner shell 600 switch from the connected state to the separated state, the inner shell 600 falls within the external gas, and at the same time, the connecting rope 410 pulls the liquid storage tank 300 to release the self-heating liquid 310 inside the liquid storage tank 300.

[0086] Please refer to the attached document. Figure 1 As shown, the inner housing 600 also includes a cover membrane 630, which is part of the inner housing 600. The inner housing 600 has a first opening at its upward-facing end, which communicates with the second receiving cavity 610. The cover membrane 630 covers the first opening to seal the inner housing 600 and prevent foreign objects from falling into the inner housing 600 through the first opening before heating is complete. Furthermore, the cover membrane 630 can achieve heat insulation within the inner housing 600.

[0087] In one embodiment, the cover membrane 630 is made of plastic or paper. The cover membrane 630 has ventilation holes to allow hot air to flow within the inner housing 600.

[0088] Please refer to the attached document. Figure 1As shown, the self-heating device also includes a cover 800. A second opening is provided at the upward-facing end of the outer shell 100. A connecting structure 700 is connected to the outer shell 100 and the inner shell 600 to close the outer shell 100. The cover 800 covers the second opening to protect the connecting structure 700. This prevents the pull ring 730 from being accidentally pulled or the membrane from being damaged. Simultaneously, the arrangement of the cover 800 and the outer shell 100 protects items stored in the first receiving cavity and further prevents moisture from entering the outer shell 100.

[0089] In one embodiment, the cover 800 and the outer shell 100 are connected by a thread or an interference fit.

[0090] In one embodiment, a second vent 810 is provided on the cover 800, and a waterproof and breathable membrane 820 is provided inside the second vent 810. This prevents the liquid storage tank 300 from rupturing unexpectedly when the inner shell 600 and the outer shell 100 are not separated. This would prevent the self-heating liquid 310 from coming into contact with the self-heating agent, generating a large amount of heat, and causing excessive pressure inside the outer shell 100, which could easily lead to spontaneous explosion. With the waterproof and breathable membrane 820 provided, pressure can be released through the second vent 810, thus preventing spontaneous explosion. Furthermore, the waterproof and breathable membrane 820 also prevents external moisture from entering the outer shell 100.

[0091] Appendix Figure 2 This application is attached Figure 1 A magnified view of a portion at point A. The connection structure 700 includes either a bolted connection structure 700 or a tear-off connection structure 700. Please refer to the attached document. Figure 2 As shown, this application employs an easy-tear connection structure 700. When the connection structure 700 employs an easy-tear connection structure 700, the connection structure 700 includes an easy-tear strip 710, which is an annular structure. The easy-tear strip 710 is circumferentially arranged around the outer shell 600, and is located between the inner shell 600 and the outer shell 100. The connection structure 700 also includes an easy-tear groove 720, through which the easy-tear strip 710 is connected to the inner shell 600 and / or the outer shell 100. In one embodiment, the easy-tear strip 710 is connected to both the inner shell 600 and the outer shell 100 via the easy-tear groove 720.

[0092] In one embodiment, the thickness at the tear mark 720 is less than the thickness of the inner shell 600, the outer shell 100, and the oil strip 710, so as to reduce the connection strength between the oil strip 710 and the inner shell 600 and / or the outer shell 100, thereby facilitating the easy separation of the oil strip 710 from the inner shell 600 and / or the outer shell 100 when the pull ring 730 pulls the oil strip 710.

[0093] In one embodiment, the tear mark 720 is a through hole surrounding the oil strip 710 and the inner housing 600 and / or the outer housing 100, so as to reduce the connection strength between the oil strip 710 and the inner housing 600 and / or the outer housing 100, thereby facilitating the easy separation of the oil strip 710 and the inner housing 600 and / or the outer housing 100 when the pull ring 730 pulls the oil strip 710.

[0094] In one embodiment, the Lewis strip 710 is made of paper or plastic material.

[0095] Please refer to the attached document. Figure 2 As shown, the connecting structure 700 also includes a pull ring 730, the first end of which is connected to the Lewis strip 710, and the second end of which extends outward.

[0096] In one embodiment, a pull hole is provided through the second end of the pull ring 730. When in use, a finger can pass through the pull hole and pull the pull ring 730 to release the connection between the inner shell 600 and the outer shell 100.

[0097] In one embodiment, the easy strip 710 has a first end and a second end. The first end of the easy strip 710 is connected to the second end of the easy strip 710 through an easy tear 720. The connection point between the pull ring 730 and the easy strip 710 is located near the first end or the second end of the easy strip 710, thereby facilitating the separation of the easy strip 710 from the inner housing 600 or the housing when the pull ring 730 is pulled.

[0098] Appendix Figure 3 This application is attached Figure 1 A magnified view of a section at point B. Please refer to the attached image. Figure 3 As shown, the storage tank 300 includes a self-heating liquid 310, which is stored in the storage tank 300. The self-heating liquid 310 is water or an aqueous solution.

[0099] The liquid storage tank 300 includes a rigid shell 320, within which a third receiving cavity is provided, in which the self-heating liquid 310 is stored. The rigid shell 320 serves to support the third receiving cavity and ensure that the liquid storage tank 300 is not easily deformed, thus preventing the liquid storage tank 300 from rupturing due to deformation impacting the inner shell 600 during transportation.

[0100] The liquid storage tank 300 also includes a waterproof membrane 330, which is disposed on the inner surface of the rigid housing 320 to prevent the self-heating liquid 310 from leaking out of the rigid housing 320.

[0101] In one embodiment, the rigid housing 320 is made of plastic or paper.

[0102] In one embodiment, the waterproof membrane 330 is made of plastic.

[0103] In one embodiment, a third opening is provided at the bottom of the rigid shell 320, and an oil strip 710 is disposed within the third opening. The oil strip 710 is connected to the rigid shell 320 via an easy-tear groove 720 to close the third opening. Further, the first end of the connecting rope 410 is connected to the oil strip 710. When the inner shell 600 falls within the outer shell 100, it forms a falling distance. The length of the connecting rope 410 is less than this falling distance, thereby ensuring that the inner shell 600 can tear the liquid storage bag 300 during its fall. The self-heating bag 200 is disposed at the bottom of the inner shell 600. Further, the thickness at the easy-tear groove 720 is less than the thickness of the rigid shell 320 and the oil strip 710, thereby reducing the connection strength between the oil strip 710 and the rigid shell 320, thus facilitating easy separation between the oil strip 710 and the rigid shell 320 when the connecting rope 410 pulls on the oil strip 710. The tear mark 720 is a through hole provided in the Lewis strip 710 and the rigid housing 320 to reduce the connection strength between the Lewis strip 710 and the rigid housing 320, thereby facilitating the easy separation between the Lewis strip 710 and the rigid housing 320 when the connecting rope 410 pulls the Lewis strip 710.

[0104] In one embodiment, the Lewis bar 710 has a first end and a second end, and the connection point between the connecting rope 410 and the Lewis bar 710 is located near the first end or the second end of the Lewis bar 710, thereby facilitating the separation of the Lewis bar 710 from the rigid housing 320 when the pull ring 730 pulls the Lewis bar 710.

[0105] The self-heating device of this application also includes a temperature display, which is disposed within the housing. Furthermore, the temperature display is disposed in a region outside the second receiving cavity within the first receiving cavity.

[0106] In one embodiment, the temperature display can be an electronic thermometer or a test paper thermometer; more specifically, this application uses a test paper thermometer. The test paper thermometer is made of a thermistor material, and the temperature display shows different colors depending on the temperature inside the casing. Furthermore, if the temperature inside the casing is higher than a first temperature, the temperature display shows red, indicating that the self-heating device is still in a heating state, and handling items to be heated at this time is likely to cause burns. If the temperature inside the casing is lower than a second temperature, the temperature display shows green, indicating that the self-heating device is in a heat-preservation state, and handling items to be heated at this time is less likely to cause burns. When the temperature inside the casing is between the first and second temperatures, the temperature display transitions from red to green.

[0107] Please refer to the attached document. Figure 1 To be continued Figure 3As shown, the specific usage of the self-heating device of this application is as follows: First, open the cover 800 to expose the pull ring 730; then pull the pull ring 730 to disconnect the connection between the inner shell 600 and the outer shell 100. Due to the weight of the inner shell 600 and the object to be heated 500, the inner shell 600 falls, and at the same time, the connecting rope 410 pulls the liquid storage bag 300, causing the liquid storage bag 300 to rupture. The self-heating liquid 310 flows to the self-heating bag 200 to generate heating heat to heat the object to be heated 500; finally, after heating is completed, puncture the film and remove the object to be heated 500.

[0108] Example 2

[0109] Please refer to the attached document. Figure 4 and appendix Figure 5 As shown, another embodiment of the self-heating device of this application is presented.

[0110] Appendix Figure 4 This is a schematic diagram of another embodiment of the self-heating device of this application. Please refer to the attached diagram. Figure 4 As shown, the self-heating device of this application is used to heat the object 500 to be heated. The self-heating device includes the object 500 to be heated, which is stored inside the device and sold together with it, thus facilitating direct heating of the object 500 by the user. In this application, the outer packaging of the object 500 can be in the form of a bag or a box, and the contents of the object 500 can be a solid or a liquid. Furthermore, the object 500 can be boxed milk or bagged traditional Chinese medicine liquid.

The upper end of the outer shell 100 is provided with a second opening, which is connected to the first receiving cavity 110. The outer shell 100 is the outermost protective device, used to protect the self-heating pack 200, the liquid storage pack 300 and the damage structure 400, and to store the object to be heated 500 in the first receiving cavity 110 of the outer shell 100 at the same time.

[0112] In one embodiment, the cross-section of the outer casing 100 is circular or rectangular.

[0113] In one embodiment, the outer casing 100 is made of a rigid, waterproof material.

[0114] In one embodiment, an insulating film is provided on the inner surface of the outer casing 100.

[0115] Please refer to the attached document. Figure 4As shown, the self-heating device of this application includes a self-heating pack 200, which is located within a first receiving cavity 110. Further, the position of the self-heating pack 200 within the first receiving cavity 110 is such that it can contact the self-heating liquid 310 flowing out after the storage pack 300 ruptures. In one embodiment, the self-heating pack 200 is located at the bottom of the first receiving cavity 110.

[0116] In one embodiment, the self-heating pack 200 includes an outer packaging bag and a self-heating agent. The self-heating agent is located inside the outer packaging bag, which is made of non-woven fabric. The main components of the self-heating agent are quicklime, sodium bicarbonate, magnesium sulfate, and other materials. The self-heating agent generates high temperature upon contact with water.

[0117] In one embodiment, the self-heating pack 200 is fixedly connected to the bottom of the first receiving cavity 110 to avoid the self-heating pack 200 impacting the liquid storage pack 300 during transportation.

[0118] Please refer to the attached document. Figure 4 As shown, the self-heating device of this application includes a liquid storage tank 300, which is located within a first receiving cavity 110. The liquid storage tank 300 contains a self-heating liquid 310 that reacts with a self-heating agent to form a self-heating reaction; the self-heating agent reacts with the self-heating liquid 310 to generate high temperatures. Furthermore, the liquid storage tank 300 is located at the top of the self-heating pack 200, so that in the event of a rupture, the self-heating liquid 310 within the liquid storage tank 300 flows into the self-heating pack 200.

[0119] In one embodiment, the self-heating liquid 310 is water or other aqueous solutions.

[0120] In one embodiment, the liquid storage bag 300 is located at the bottom of the inner shell 600, and the liquid storage bag 300 is fixedly connected to the bottom of the inner shell 600.

[0121] Please refer to the attached document. Figure 4 As shown, the self-heating device of this application includes an inner shell 600, which is located within a first receiving cavity 110. The inner shell 600 has a second receiving cavity 610, which is also located within the first receiving cavity 110; that is, the second receiving cavity 610 is a part of the first receiving cavity 110. A first vent hole 620 is provided at the bottom of the inner shell 600 to allow the heat generated after the self-heating agent encounters the self-heating liquid 310 to enter the inner shell 600 through the first vent hole 620.

[0122] In one embodiment, the cross-section of the inner housing 600 is circular or rectangular.

[0123] In one embodiment, the object to be heated 500 is located in the second receiving cavity 610, and the self-heating pack 200 and the liquid storage pack 300 are located in the area outside the second receiving cavity 610 within the first receiving cavity 110.

[0124] In one embodiment, the top of the inner housing 600 is flush with the top of the outer housing 100.

[0125] Please refer to the attached document. Figure 4 As shown, the inner shell 600 of this application also includes an intermediate plate 640. In this application, two intermediate plates 640 are provided, arranged laterally within the inner shell 600. The first ends of the two intermediate plates 640 are connected to the inner shell 600, and the second ends of the two intermediate plates 640 are spaced apart to form a central hole. The two intermediate plates 640 are spaced apart from the ground of the inner shell 600. The object to be heated 500 is placed above the intermediate plates 640, and the heating heat is generated through the intermediate spacer to heat the object to be heated 500. A first distance exists between the two intermediate plates 640 and the bottom of the inner shell 600.

[0126] Please refer to the attached document. Figure 4 As shown, the destructive structure 400 of this application also includes a horizontal plate assembly 420. The horizontal plate assembly 420 is disposed between the liquid storage bag 300 and the self-heating bag 200. The horizontal plate assembly 420 includes a left horizontal plate 421 and a right horizontal plate that are spaced apart from each other. A water-permeable gap 430 is formed between the left horizontal plate 421 and the right horizontal plate. Both the left horizontal plate 421 and the right horizontal plate 422 are connected to the outer shell 100.

[0127] Please refer to the attached document. Figure 4 As shown, the self-heating device of this application also includes a breaking structure 400, which is used to break the water tank so that the self-heating liquid 310 in the storage tank 300 can flow to the self-heating pack 200 to generate heating heat, which is used to directly heat the object 500 to be heated.

[0128] In this application, the destructive structure 400 includes a needle 440 disposed between the liquid storage tank 300 and the self-heating pack 200. A first end of the needle 440 is connected to the horizontal plate assembly 420, and a second end of the needle 440 is positioned towards the liquid storage tank 300. The second end of the needle 440 is spaced apart from the liquid storage tank 300 to prevent accidental puncture of the liquid storage tank 300. The second end of the needle 440 is provided with a spike.

[0129] In one embodiment, the length of the needle 440 is less than the first distance to prevent the needle 440 from entering the inner housing 600 through the first vent 620 and accidentally puncturing the heated object 500.

[0130] In one embodiment, the diameter of the needle 440 is smaller than the diameter of the first water-permeable hole to prevent the needle 440 from entering the inner housing 600.

[0131] Please refer to the attached document. Figure 4As shown, the self-heating device of this application also includes a connecting structure 700. The inner shell 600 is detachably connected to the outer shell 100 through the connecting structure 700. With the inner shell 600 and the outer shell 100 detachably connected, the outer shell 100 and the inner shell 600 are in a connected state and a separated state.

[0132] In the connected state, the outer shell 100 is connected to the inner shell 600 via the connecting structure 700, and the relative position between the breaking structure 400 and the liquid storage tank 300 is fixed, thus ensuring that the breaking structure 400 is unlikely to accidentally break the liquid storage tank 300. In the separated state, the outer shell 100 and the inner shell 600 are separated, and displacement occurs between the breaking structure 400 and the liquid storage tank 300. The breaking structure 400 breaks the liquid storage tank 300, and the self-heating liquid 310 inside the liquid storage tank 300 flows to the self-heating pack 200. Furthermore, when the outer shell 100 and the inner shell 600 switch from the connected state to the separated state, the inner shell 600 falls within the external gas, and at the same time, the connecting rope 410 pulls the liquid storage tank 300 to release the self-heating liquid 310 inside the liquid storage tank 300.

[0133] Please refer to the attached document. Figure 4 As shown, the inner housing 600 also includes a cover membrane 630, which is part of the inner housing 600. The inner housing 600 has a first opening at its upward-facing end, which communicates with the second receiving cavity 610. The cover membrane 630 covers the first opening to seal the inner housing 600 and prevent foreign objects from falling into the inner housing 600 through the first opening before heating is complete. Furthermore, the cover membrane 630 can achieve heat insulation within the inner housing 600.

[0134] In one embodiment, the cover membrane 630 is made of plastic or paper. The cover membrane 630 has ventilation holes to allow hot air to flow within the inner housing 600.

[0135] Please refer to the attached document. Figure 4 As shown, the self-heating device also includes a cover 800. A second opening is provided at the upward-facing end of the outer shell 100. A connecting structure 700 is connected to the outer shell 100 and the inner shell 600 to close the outer shell 100. The cover 800 covers the second opening to protect the connecting structure 700. This prevents the pull ring 730 from being accidentally pulled or the membrane from being damaged. Simultaneously, the arrangement of the cover 800 and the outer shell 100 protects items stored in the first receiving cavity 110 and further prevents moisture from entering the outer shell 100.

[0136] In one embodiment, the cover 800 and the outer shell 100 are connected by a thread or an interference fit.

[0137] In one embodiment, a second vent 810 is provided on the cover 800, and a waterproof and breathable membrane 820 is provided inside the second vent 810. This prevents the liquid storage tank 300 from rupturing unexpectedly when the inner shell 600 and the outer shell 100 are not separated. This would prevent the self-heating liquid 310 from coming into contact with the self-heating agent, generating a large amount of heat, and causing excessive pressure inside the outer shell 100, which could easily lead to spontaneous explosion. With the waterproof and breathable membrane 820 provided, pressure can be released through the second vent 810, thus preventing spontaneous explosion. Furthermore, the waterproof and breathable membrane 820 also prevents external moisture from entering the outer shell 100.

[0138] Appendix Figure 5 This application is attached Figure 4 A magnified view of section C in the middle. Please refer to the attached image. Figure 5 As shown, the storage tank 300 includes a self-heating liquid 310, which is stored in the storage tank 300. The self-heating liquid 310 is water or an aqueous solution.

[0139] The liquid storage tank 300 includes a rigid shell 320, within which a third receiving cavity is provided, in which the self-heating liquid 310 is stored. The rigid shell 320 serves to support the third receiving cavity and ensure that the liquid storage tank 300 is not easily deformed, thus preventing the liquid storage tank 300 from rupturing due to deformation impacting the inner shell 600 during transportation.

[0140] The liquid storage tank 300 also includes a waterproof membrane 330, which is disposed on the inner surface of the rigid housing 320 to prevent the self-heating liquid 310 from leaking out of the rigid housing 320.

[0141] In one embodiment, the rigid housing 320 is made of plastic or paper.

[0142] In one embodiment, the waterproof membrane 330 is made of plastic.

[0143] The self-heating device of this application also includes a temperature display, which is disposed within the housing. Furthermore, the temperature display is disposed in a region outside the second receiving cavity within the first receiving cavity.

[0144] In one embodiment, the temperature display can be an electronic thermometer or a test paper thermometer; more specifically, this application uses a test paper thermometer. The test paper thermometer is made of a thermistor material, and the temperature display shows different colors depending on the temperature inside the casing. Furthermore, if the temperature inside the casing is higher than a first temperature, the temperature display shows red, indicating that the self-heating device is still in a heating state, and handling items to be heated at this time is likely to cause burns. If the temperature inside the casing is lower than a second temperature, the temperature display shows green, indicating that the self-heating device is in a heat-preservation state, and handling items to be heated at this time is less likely to cause burns. When the temperature inside the casing is between the first and second temperatures, the temperature display transitions from red to green.

[0145] Please refer to the attached document. Figure 4 and attached Figure 5 As shown, the specific usage of the self-heating device of this application is as follows: First, open the cover 800 to expose the pull ring 730; then pull the pull ring 730 to disconnect the connection between the inner shell 600 and the outer shell 100. Due to the weight of the inner shell 600 and the object to be heated 500, the inner shell 600 falls to the piercing needle 440. The piercing needle 440 punctures the liquid storage bag 300 and releases the self-heating liquid 310. The self-heating liquid 310 flows to the self-heating agent to generate heating heat to heat the object to be heated 500; finally, after heating is completed, puncture the film and remove the object to be heated 500.
