[0027] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0028] The present invention provides a self-heating beverage can with pressure relief, such as Figure 1 As shown, it includes an inner liner 1, an insulating outer shell 2 and a base 3, the inner liner 1 is arranged in the insulating outer shell 2, the inner liner 1 is fixedly connected to the base 3, and the insulating outer shell 2 is connected to the base 3; the inner liner 1 includes a reaction part 11 and a heating part 12, the reaction part 11 contains water, and the heating part 12 contains medicine that can react with water to release heat, the reaction part 11 and the heating part 12 are fixedly connected, and the reaction part 11 and the heating part 12 are connected, a protective film 13 is provided between the reaction part 11 and the heating part 12, the heating part 12 is cylindrical, and the outer wall of the heating part 12 is in contact with the beverage liquid, a pushing structure 14 is provided in the reaction part 11, and a pressure relief structure 15 is provided on the top of the heating part 12, and the pressure relief structure 15 is connected to the insulating outer shell 2.

[0029] Through the above-mentioned structural setting, when the beverage needs to be heated, the pushing structure 14 is used to penetrate the protective film 13, so that the medicine in the heating part 12 falls into the reaction part 11 through the hole on the protective film 13, so that the medicine reacts with water to emit heat, and the heat is transferred to the beverage through the heating part 12. The reaction part 11 is a cylinder, which greatly increases the contact area with the beverage liquid and greatly accelerates the heat transfer speed. When the heating part 12 increases with the temperature and the air pressure increases, the gas can be released through the pressure relief structure 15, thereby achieving a protective effect.

[0030] In some embodiments, as Figure 1 、 Figure 3 and Figure 4 As shown, the pressure relief structure 15 includes a pressure relief hole 151, a pressure relief column 152 and a pressure relief cover 153. The pressure relief hole 151 is provided at the top of the heating portion 12, the pressure relief column 152 is slidably connected to the pressure relief hole 151, the pressure relief cover 153 is connected to a pressure relief channel 154, and the pressure relief channel 154 is connected to the heat insulation shell 2, the pressure relief column 152 is provided with fixing plates 155 at both ends, the diameter of the fixing plates 155 is larger than the diameter of the pressure relief hole 151, the bottom of the pressure relief column 152 is provided with an exhaust channel 156, and the side wall of the pressure relief column 152 is provided with multiple exhaust ports 157, and the exhaust ports 157 are connected to the exhaust channel 156.

[0031] Through the above-mentioned structural setting, when the gas pressure of the heating part 12 is too high, the gas will push the pressure relief column 152 to rise, so that the exhaust port 157 rises from the bottom of the pressure relief hole 151 to the top of the pressure relief hole 151, and the gas can be discharged into the pressure relief cover 153 through the exhaust port 157 from the exhaust channel 156. Finally, the gas is discharged into the thermal insulation shell 2 through the pressure relief channel 154.

[0032] In some embodiments, as Figure 2 As shown, an air guide channel 21 is opened in the side wall of the heat-insulating shell 2 , the air guide channel 21 is connected to the exhaust channel 156 , and the air guide channel 21 passes through the heat-insulating shell 2 and the base 3 .

[0033] Through the above-mentioned structural arrangement, the gas discharged into the heat-insulating shell 2 through the pressure relief channel 154 can be discharged along the gas guide channel 21 .

[0034] In some embodiments, as Figure 1 As shown, the pushing structure 14 includes a puncture column 141 and a pushing block 142 . The puncture column 141 is fixedly connected to the pushing block 142 . The pushing block 142 passes through the base 3 , and the pushing block 142 is slidably connected to the base 3 .

[0035] With the above-mentioned structural arrangement, when the beverage needs to be heated, the pushing block 142 is pushed, thereby pushing the puncture column 141 upward, so that the puncture column 141 punctures the protective film 13 .

[0036] In some embodiments, as Figure 1 As shown, an annular disk 143 is sleeved on the bottom of the puncture column 141 , and the edge of the annular disk 143 abuts against the inner wall of the reaction part 11 .

[0037] With the above-mentioned structural arrangement, when the puncture column 141 rises, the annular disk 143 also drags the water in the reaction part 11 upward, thereby preventing the water from flowing out from the gap between the pushing block 142 and the base 3 .

[0038] In some embodiments, as Figure 1 As shown, a fixing ring 144 is provided at the bottom of the puncture column 141 , and the fixing ring 144 abuts against the base 3 .

[0039] With the above-mentioned structural arrangement, the fixing ring 144 can prevent the puncture column 141 from sliding out of the reaction part 11 due to inertia when it descends.

[0040] In some embodiments, as Figure 1 and Figure 5 As shown, the base 3 is provided with an annular groove 31 , and the bottom of the heat-insulating shell 2 is engaged with the annular groove 31 .

[0041] The above-mentioned structural arrangement can make the heat-insulating shell 2 more stable.

[0042] In summary, when the beverage needs to be heated, the push block 142 will be moved so that the puncture column 141 will pierce the protective film 13, so that the medicine in the heating part 12 will fall into the reaction part 11 through the hole in the protective film 13, so that the medicine reacts with water to emit heat, and the heat is transferred to the beverage through the heating part 12. The reaction part 11 is a cylinder, which greatly increases the contact surface with the beverage liquid and greatly accelerates the heat transfer speed. When the heating part 12 increases with the temperature and the air pressure increases, the gas will lift the pressure relief column 152, so that the exhaust port 157 rises from the bottom of the pressure relief hole 151 to the top of the pressure relief hole 151. The gas can be discharged from the exhaust channel 156 through the exhaust port 157 into the pressure relief cover 153, and finally the gas is discharged from the pressure relief channel 154 into the air guide channel 21 in the heat-insulating shell 2, so that the gas is released, thereby achieving a protective effect.

[0043] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0044] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0045] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
