[0020] like Figures 1 to 4 As shown, the non-AC powered fireless heating system of the preferred embodiment of the present invention comprises a heater body 1, an open-top heater housing 2, and a container 3 for accommodating objects to be heated. In this embodiment, the heating system is used to heat food, and the container 3 is a food pan made of a heat-conducting material for accommodating food to be heated. In this embodiment, the heat-conducting material is stainless steel.

[0021] The heater body 1 is formed integrally of four compartments 4, a box-shaped cover 8, an activation liquid receiving portion 5 and a controller housing 6. Each compartment 4 is used to receive a liquid-activated heating element. In the present embodiment, the liquid-activated heating element is a water-activated heating pack, which is activated by water to release heat energy over a period of about half an hour. Such a water-activated heating pack belongs to the prior art, so its structure is not described in detail here. The activation liquid receiving portion 5 is used to receive a liquid that activates the liquid-activated heating element to release heat energy, and in the present embodiment, the liquid is water. The liquid guiding device 7 guides a specific amount of liquid in the activation liquid receiving portion 5 to the four compartments 4 in a sequential manner, wherein the specific amount is an amount sufficient to activate the liquid-activated heating element in the compartment 4.

[0022] The liquid guiding device 7 includes four pumps 71, a controller 72 and a power supply 73. The four pumps 71 are located in the activation liquid containing part 5. The four pumps 71 are respectively arranged corresponding to the four compartments 4, and are operably connected to the conduit 74 to pump the liquid in the activation liquid containing part 5 to the corresponding compartment 4. The controller 72 is operably connected to the four pumps 71 to sequentially start the pumps 71 to pump a specific amount of liquid in the activation liquid containing part 5 to the compartment 4, wherein the specific amount is an amount sufficient to activate the heating element activated by the liquid in the activation compartment 4. The power supply 73 is a battery, which is electrically connected to the controller 72 and the pump 71 to supply power to the controller 72 and the pump 71. The controller 72 and the power supply 73 are accommodated in the controller housing 6.

[0023] In this embodiment, four compartments 4 are arranged adjacent to each other. The tops of the four compartments 4 are covered with a box-shaped cover 8. The box-shaped cover 8 includes a bottom plate 81, a top plate 82 and four side plates 83. The bottom plate 81 is provided with four groups of through holes 811, and each group of through holes 811 is respectively provided corresponding to the four compartments 4. The top plate 82 is provided with a central opening 821. The open-top heater housing 2 is provided with a bottom 21 and a top 22. The bottom 21 accommodates a heater body 1 composed of a controller housing 6, four compartments 4, a box-shaped cover 8 and an activation liquid containing portion 5. The top 22 accommodates a container 3. The open-top heater housing 2 is made of a heat-insulating material. There is a gap between the top plate 82 of the box-shaped cover 8 and the container 3, and there is also a gap between the open-top heater housing 2 and the container 3, so that the water vapor generated when the water in the compartment 4 is heated can be discharged.

[0024] The operating principle of this embodiment is as follows: (1) place the heater body 1 at the bottom 21 of the open-top heater housing 2; (2) place a water-activated heating pack in each compartment 4, and then cover the four compartments 4 with a box-shaped cover 8; (3) inject water into the activation liquid receiving portion 5; (4) start the controller 72; (5) place the container 3 at the top 22 of the open-top heater housing 2. When the controller 72 is started, the controller 72 first starts the first pump 71 to pump a specific amount of water in the activation liquid receiving portion 5 to the first compartment 4, wherein the specific amount is an amount sufficient to activate the water-activated heating pack in the first compartment 4. When the water-activated heating pack in the first compartment 4 is activated by water, it releases heat energy and heats the water in the first compartment 4 and generates water vapor; the water vapor is discharged through the through hole 811 of the bottom plate 81 corresponding to the first compartment 4, diffuses in the box-shaped cover 8, and then discharged through the central opening 821 of the top plate 82, the gap between the top plate 82 of the box-shaped cover 8 and the container 3, and the gap between the open-top heater shell 2 and the container 3. Due to the release of heat energy, the heater body 1 becomes very hot; the open-top heater shell 2 made of heat-insulating material can prevent the user's hands from being injured when touching the present invention. After half an hour has passed, that is, after the time that the water-activated heating pack can generate heat after being activated has passed, the controller 72 starts the second pump 71 to pump a specific amount of water in the activation liquid receiving portion 5 to the second compartment 4, wherein the specific amount is sufficient to activate the water-activated heating pack in the second compartment 4. Then the above process is repeated until all four compartments 4 have been filled with water, and heating can be provided for two hours without manual operation during the period.

[0025] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
