The lunch box has another advantage that a safety pressure relief valve is arranged on the outer box, it can be guaranteed that the space for containing the mantle heater has pressure so that the lunch box can have better heating effect, and the safety pressure relief valve has the protection effect.
Description
Technical field
The present invention relates to a kind of lunch box capable of heating, specifically a kind of need not fire, not electricity consumption just can self-heating outdoor lunch box capable of heating.
Background technology
Most is applied to the method for Portable heating and insulation, to depend on as propane, butane, the fuel of unleaded gas or its gas mixing or liquid, but the heating process of using liquid fuel and gaseous fuel often needs the hot production mechanism of more complicated height, because it relates to more workpiece, like this parts placed under repair and replace and will be difficult to, maintenance and the expense of changing also can be higher, although if adopt the heater meeting of fuel rod and fuel flat board both economical, but shortcoming is that the firing rate of food is slower, be exactly that the flame that produces of most of Portable cooking systems needs windproof barrier guarantee that flame does not extinguish in addition, on market, exist now a kind of lunch box capable of heating being formed by lunch box body and heater, utilize coal briquette burning to heat food, play the effect to lunch box insulation within a certain period of time, heater is provided with fan, the speed of capable of adjusting air inlet mouth air intake is controlled the speed of coal briquette burning, when but shortcoming is to use, be the heating means that must use kindling material to light, use inconvenience and dangerous, the electric heating contant temperature lunch box that also has a kind of PTC of utilization semiconductive ceramic electric heating element, temperature in lunch box rises to 110 while spending, can automatically reduce electrical power, make lunch box carry out temperature constant state, avoid sticking with paste meal and save electric energy, but weak point be, must in the situation that having power supply, could use, environment for use is subject to larger restriction, can not use in the wild, moreover be exactly to be a kind ofly from lunch box capable of heating, by outer box, lid, fixed support, rotation handle, inner bag and heating agent etc., to be formed, in the middle of box and inner bag, leave space outside, in the space of box and inner bag, be provided with outside removable water bag and calcium oxide heating bag, shortcoming is to carry and open inconvenience, and unreliable.
Summary of the invention
The object of this invention is to provide a kind of outdoor lunch box capable of heating from heating, can be used to cook, also can be used for being incubated, and simple in structure, and volume is little, lightweight, easy to carry, more safe and reliable during use.
Technical scheme of the present invention is achieved in that outdoor lunch box capable of heating, comprise outer box, inner bag, lid, inner bag is nested in outer box, and leave heating space for placing heat packs between inner bag bottom and outer box, lid is added a cover in outer box top, safety relief valve is installed on the sidewall of outer box and is communicated with heating space.Outer box is to adopt vacuum design, can play for a long time insulation effect; Safety relief valve can guarantee that the space of putting heat packs can exist pressure, makes it reach better heating effect, and safety relief valve plays a protective role, and when internal pressure is excessive, safe safety relief valve is opened automatically, plays the effect of pressure release.Described safety relief valve is provided with spring, O type circle and pad.Lid is provided with a circle sealing strip, and outer box top edge is provided with a circle sealing strip, plays the effect of sealing, guarantees the sealing of inner space, strengthens heat insulation effect, in addition also Leakage prevention.Fixed by snap between outer box and lid.Outer box lateral surface is provided with anti-skidding soft rubber sleeve.Inner bag surrounding is surrounded by plastic protective sleeve, can protect stainless steel inner container.
Lunch box capable of heating not only can heat food, and can in the container that uses inner bag, keep super higher temperature after an hour, and it can also be before food heats, serve as a leakproof, anti-overflow device afterwards; When you do not need to heat book food, not that it can also use as incubation canteen.
Described heat packs is put in the bottom of outer box, suitable quantity of water is poured into the outer box of putting into heat packs, just can make heat packs that chemical reaction occurs rapidly, produce a large amount of heats, make the temperature in lunch box or cup increase rapidly, but add water effect depend on the size of heat packs and pour into the water yield number, the temperature that finally can reach and outside weather, environment and the kind etc. of putting into food have relation.The external packing of heat packs is to be made by a kind of material of porous, and heating material is wrapped in to inside.External packing is polyethylene/LDPE paper, and water can be penetrated wherein, and chemical reaction fully occurs, and inner heat packs composition can not infiltrate yet.
Inner bag of the present invention is to be made by resistant to elevated temperatures stainless steel material, and outer box is made by food stage PP material, and food stage PP is food-grade polypropylene plastics, few stripping harmful substance under normal condition and high-temperature condition; Inner bag is to need the food of heating or water for placing, outer box is for placing the heat packs of porous, heat packs and water reaction releases heat, inner bag is positioned in outer box, the food and the water that in the heat heating inner box that in outer box, heat packs generates after being activated, need heating, the lid of sealing has effectively been preserved heat to the full extent.
Beneficial effect of the present invention is: this lunch box can be used to cook, also can be used for being incubated, and simple in structure, and volume is little, lightweight, easy to carry, heat time is short, and safe and reliable, convenient unlatching and operation, just can heat without naked light, also without electricity consumption, be applicable to various environment, low price in the time of safe and reliable, is widely used.Another feature of the present invention is provided with safety relief valve on box outside, can guarantee that the space of putting heat packs can exist pressure, make it reach better heating effect, and safety relief valve plays a protective role.
