Detailed ways

As shown in FIGS. 1 to 4 , the non-AC-powered fire-free heating system according to the preferred embodiment of the present invention includes a heater body 1 , an open-top heater casing 2 , and a container 3 for accommodating objects that need to be heated. In this embodiment, the heating system is used for heating food, and the container 3 is a food tray made of thermally conductive material for accommodating food to be heated, in this embodiment, the thermally conductive material is stainless steel.

The heater body 1 is composed of four compartments 4 , a box-shaped cover 8 , an activation liquid accommodating portion 5 and a controller housing 6 , which are integrally formed. Each compartment 4 is intended to house a liquid-activated heating element. In this embodiment, the liquid-activated heating element is a water-activated heating pack, which is activated with water to release thermal energy over a period of approximately half an hour. Such water-activated heating packs belong to the prior art, so their construction will not be described in detail here. The activation liquid accommodating part 5 is used for accommodating the liquid which activates the liquid-activated heating element to release thermal energy, and in this embodiment, the liquid is water. The liquid guide 7 directs a specific amount of liquid in the activation liquid receptacle 5 to the four compartments 4 in sequence, wherein the specific amount is an amount sufficient to activate the liquid-activated heating element in the compartment 4 .

The liquid guiding device 7 includes four pumps 71 , a controller 72 and a power source 73 . Four pumps 71 are located within the activation liquid receptacle 5 . The four pumps 71 are respectively provided corresponding to the four compartments 4 and are operatively connected to the conduits 74 for pumping the liquid in the activation liquid receptacle 5 to the corresponding compartment 4 . The controller 72 is operatively connected to the four pumps 71 to activate the pumps 71 in sequence to pump a specified amount of liquid within the activation liquid receptacle 5 to the compartment 4, wherein the specified amount is sufficient to activate the compartment 4 The amount of liquid activated heating element inside. The power source 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 source 73 are accommodated in the controller housing 6 .

In this embodiment, four compartments 4 are arranged adjacently. The tops of the four compartments 4 are covered with box-like lids 8 . The box-shaped cover body 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 disposed 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 the heater body 1 consisting of the controller housing 6 , the four compartments 4 , the box-shaped cover 8 and the activation liquid accommodating portion 5 . The top 22 houses the container 3 . The open top heater housing 2 is made of 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 shell 2 and the container 3, so that the water vapor generated when the water in the compartment 4 is heated is discharged.

The operating principle of this embodiment is as follows: (1) place the heater body 1 on the bottom 21 of the open-top heater housing 2; (2) place a water activated heating pack in each compartment 4, and then use the box cover 8 covers the four compartments 4; (3) injects water into the activation liquid container 5; (4) activates the controller 72; (5) places the container 3 on the top 22 of the open top heater housing 2. When the controller 72 is activated, the controller 72 first activates the first pump 71 to pump a specific amount of the activation liquid receptacle 5 into the first compartment 4, wherein the specified amount is sufficient to activate the first The water in compartment 4 activates the portion size of the heating pack. When the water-activated heating pack in the first compartment 4 is activated by water, heat energy is released and the water in the first compartment 4 is heated and water vapor is generated; The through hole 811 of the bottom plate 81 is discharged and spreads in the box-shaped cover 8 , and then passes 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 open-top heater casing 2 and the space between the container 3 is discharged. The heater body 1 becomes very hot due to the released thermal energy; the open-top heater housing 2 made of insulating material prevents the user's hands from being injured when touching the present invention. After half an hour has elapsed, that is, after the water-activated heating pack is activated, the controller 72 activates the second pump 71 to pump a specific amount of the activated liquid container 5 to the first Two compartments 4 , wherein the specified amount is an amount sufficient to activate the water-activated heating pack in the second compartment 4 . The foregoing process is then repeated until all four compartments 4 have been filled with water and are available for heating for two hours without manual intervention.

The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited by the above embodiments, and any other changes, modifications, substitutions, combinations, simplifications made without departing from the spirit and principle of the present invention , all should be equivalent replacement modes, and all are included in the protection scope of the present invention.
