An inner liner is fixedly installed on the inner side of the housing.

[0009] A further improvement of the present invention is that a water storage tank is provided between the outer shell and the inner liner, and an exhaust hole is provided on the surface of the outer shell. Multiple sets of exhaust holes are provided, and the exhaust holes are evenly distributed on the surface of the outer shell.

[0010] A further improvement of this utility model is that a sealing ring is fixedly installed at the bottom of the outer shell, and a threaded boss is fixedly installed on the surface of the outer shell.

[0011] A further improvement of the present invention is that the heating component includes a base, the base is movably mounted on the surface of the outer shell, anti-slip blocks are fixedly mounted and evenly distributed on the surface of the base, a fixed connection point is fixedly connected to the surface of the outer shell, and a threaded groove is provided on the inner side of the base, the threaded groove being adapted to the threaded boss.

[0012] A further improvement of this utility model is that: a fixing frame is fixedly installed on the surface of the base, the fixing frame is movably installed on the surface of the heating pack, and the surface of the fixing frame is provided with multiple sets of connecting grooves.

[0013] A further improvement of this utility model is that: a column is fixedly installed on the surface of the base, and two sets of columns are provided. The columns are symmetrically distributed on both sides of the fixing frame, and a scraper is fixedly installed on the top of the column.

[0014] A further improvement of the present invention is that the heating assembly further includes a movable ring, which is movably connected to the surface of the support ring. A support rod is movably mounted on the surface of the movable ring. The bottom end of the support rod is fixedly mounted on the surface of the base. A fixing ring is fixedly mounted on the top end of the support rod. The fixing ring is movably mounted inside the water storage tank.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a portable self-heating device, which uses an inner liner, outer shell, water storage tank, vent, threaded boss, support ring, waterproof membrane, and sealing ring. The inner liner holds food and is made of aluminum with an anti-corrosion coating on the inside. It connects to the outer shell at the top, and the outer shell has a heat insulation layer. The inner liner and outer shell fit together to form a water storage tank at the bottom, storing a fixed amount of water that reacts with the heating pack. The waterproof membrane on the support ring at the bottom isolates the heating pack from the water inside the storage tank.

This utility model provides a portable self-heating device, which employs a support rod, a fixing ring, a protrusion, a base, an anti-slip block, a movable ring, a fixing frame, a column, a scraper, a threaded groove, and a fixed connection point. The base is connected to the outer shell via the fixed connection point on its surface to prevent the base from moving freely, thus preventing the scraper from puncturing the waterproof membrane during transportation. In use, by twisting the base, the anti-slip block on the base surface increases friction. At this time, the threaded protrusion rotates inside the threaded groove, causing the placement component to move downwards until the waterproof membrane contacts the scraper at the top of the column. During rotation, the scraper scrapes against the waterproof membrane, causing it to rupture, allowing water from the water storage tank to enter the base and the fixing frame. The heating pack in the inner pot reacts and heats the food inside. The fixing frame prevents the heating pack from moving freely. In the fixed state, it can be quickly wetted to achieve a rapid heating effect. The connecting groove on the surface of the fixing frame increases the contact area with water. At the same time, when the placement component rotates downward, the support ring rotates on the surface of the movable ring and moves downward. The fixing ring at the top of the support rod remains stationary and causes the protrusion to disengage from the vent. The steam generated by the reaction is discharged through the vent. The surface of the support rod is equipped with a rubber sleeve to prevent water from flowing out from the gap between the support rod and the movable ring. This device can be turned quickly to heat food, reducing operation steps and improving the adaptability of the device. Attached Figure Description

[0025] Example 1

[0026] like Figure 1-5 As shown, this utility model provides a portable self-heating device, including a heating pack 1, a storage component 2 on the surface of the heating pack 1, a heating component 3 on the surface of the storage component 2, the storage component 2 including a shell 202, the shell 202 being fixedly connected to the surface of the heating component 3, a support ring 206 being fixedly installed at the bottom end of the shell 202, a water-resistant membrane 207 being fixedly connected to the surface of the support ring 206, an inner liner 201 being fixedly installed inside the shell 202, a water storage tank 203 being provided between the shell 202 and the inner liner 201, an exhaust hole 204 being provided on the surface of the shell 202, multiple sets of exhaust holes 204 being evenly distributed on the surface of the shell 202, a sealing ring 208 being fixedly installed at the bottom end of the shell 202, and a threaded boss 205 being fixedly installed on the surface of the shell 202.

[0027] In this embodiment, food is held in an inner liner 201. The inner liner 201 is made of aluminum with an anti-corrosion coating on the inside and is connected to the outer shell 202 at its top. The outer shell 202 has a heat insulation layer on its surface. The inner liner 201 and the outer shell 202 cooperate to form a water storage tank 203 between them and the bottom, which is used to store a certain amount of water that reacts with the heating pack 1. A water-proof film 207 on the surface of the bottom support ring 206 is used to isolate the heating pack 1 from the water inside the water storage tank 203. At the same time, the surface of the outer shell 202... Multiple sets of vent holes 204 are provided, which are inclined downward at a 45-degree angle to discharge steam and prevent deformation of the outer shell 202. When not in use, they are sealed by the protrusion 303 to prevent water from flowing out of the water storage tank 203. A sealing ring 208 is provided at the bottom of the outer shell 202 to seal the gap between the storage component 2 and the heating component 3, preventing the heating pack 1 from coming into contact with humid air during transportation and also preventing steam from escaping from the gap when in use, thus improving the adaptability of the device.

[0028] Example 2

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the heating component 3 includes a base 304, which is movably mounted on the surface of the outer shell 202. Anti-slip blocks 305 are fixedly mounted and evenly distributed on the surface of the base 304. A fixed connection point 311 is fixedly connected to the surface of the outer shell 202. A threaded groove 310 is provided on the inner side of the base 304, which is adapted to the threaded boss 205. A fixing bracket 307 is fixedly mounted on the surface of the base 304, and is movably mounted on the surface of the heating pack 1. Multiple sets of connecting grooves are provided on the surface of the base 304. The surface of the base 304 is fixedly mounted with columns 308. There are two sets of columns 308, which are symmetrically distributed on both sides of the mounting frame 307. The top of the column 308 is fixedly mounted with a scraper 309. The heating component 3 also includes a movable ring 306, which is movably connected to the surface of the support ring 206. The surface of the movable ring 306 is movably mounted with a support rod 301. The bottom end of the support rod 301 is fixedly mounted on the surface of the base 304. The top end of the support rod 301 is fixedly mounted with a fixing ring 302. The fixing ring 302 is movably mounted inside the water storage tank 203. The surface of the fixing ring 302 is evenly distributed and fixedly mounted with protrusions 303, which are adapted to the vent 204.

[0030] In this embodiment, the base 304 is connected to the outer shell 202 via a fixed connection point 311 on its surface to prevent the base 304 from moving freely. This prevents the scraper 309 from puncturing the waterproof membrane 207 during transportation. During use, twisting the base 304 increases friction on the anti-slip block 305 on its surface. The threaded boss 205 rotates within the threaded groove 310, causing the storage assembly 2 to move downwards until the waterproof membrane 207 contacts the scraper 309 at the top of the column 308. During rotation, the scraper 309 scrapes against the waterproof membrane 207, causing it to rupture. Water from the water storage tank 203 enters the base 304, reacting with the heating pack 1 inside the fixing frame 307. The resulting temperature rise heats the inner liner 201. The food inside is heated, and the fixing frame 307 prevents the heating pack 1 from moving freely. In the fixed state, it can be quickly wetted to achieve a rapid heating effect. The connecting groove on the surface of the fixing frame 307 increases the contact area with water. At the same time, when the placement component 2 rotates downward, the support ring 206 rotates on the surface of the movable ring 306 and moves downward. The fixing ring 302 at the top of the support rod 301 remains stationary, and the protrusion 303 disengages from the exhaust hole 204. The steam generated by the reaction is discharged through the exhaust hole 204. The surface of the support rod 301 is provided with a rubber sleeve to prevent water from flowing out from the gap between the support rod 301 and the movable ring 306. This device can be turned quickly to heat food, reducing operation steps and improving the adaptability of the device.

[0031] The working principle of this portable self-heating device will be explained in detail below.

[0032] like Figure 1-5 As shown, food is held in the inner liner 201, which is made of aluminum with an anti-corrosion coating on the inside. It connects to the outer shell 202 at the top. The outer shell 202 has a heat-insulating layer on its surface. The inner liner 201 and the outer shell 202 work together to form a water tank 203 at the bottom, storing a fixed amount of water that reacts with the heating pack 1. A waterproof film 207 on the surface of the bottom support ring 206 isolates the heating pack 1 from the water inside the water tank 203. The outer shell 202 has multiple sets of vents 204, which are angled downwards at a 45-degree angle to release steam and prevent... To prevent deformation of the outer shell 202, the protrusion 303 seals the water tank 203 when not in use, preventing water from leaking out. A sealing ring 208 is provided at the bottom of the outer shell 202 to seal the gap between the storage component 2 and the heating component 3, preventing the heating pack 1 from coming into contact with humid air during transportation and also preventing steam from escaping through the gap during use. The fixing connection point 311 on the surface of the base 304 connects to the outer shell 202, preventing the base 304 from moving freely and causing the scraper 309 to puncture the waterproof membrane 207 during transportation. During use, the base 304 is rotated... The anti-slip block 305 on the surface of 04 increases friction. At this time, the threaded boss 205 rotates inside the threaded groove 310, causing the storage assembly 2 to move downwards until the waterproof membrane 207 contacts the scraper 309 at the top of the column 308. During rotation, the scraper 309 scrapes against the waterproof membrane 207, causing it to rupture. Water from the water storage tank 203 enters the base 304 and reacts with the heating pack 1 inside the fixing frame 307. After heating, it heats the food inside the inner liner 201. The fixing frame 307 prevents the heating pack 1 from moving freely. In its fixed state, it can quickly wet the food to achieve… The device achieves rapid heating and increases the contact area with water through the connecting groove on the surface of the fixed frame 307. Simultaneously, when the placement assembly 2 rotates downwards, the support ring 206 rotates on the surface of the movable ring 306 and moves downwards, ensuring the fixed ring 302 at the top of the support rod 301 remains stationary and disengaging the protrusion 303 from the exhaust port 204. The steam generated by the reaction is discharged through the exhaust port 204. A rubber sleeve is provided on the surface of the support rod 301 to prevent water from flowing out through the gap between the support rod 301 and the movable ring 306. This device can be rotated to quickly heat food, reducing operating steps and improving the adaptability of the device.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
