Abstract

The utility model discloses a portable heat-insulation box which comprises a box body, a sealing cover of the box body, a control circuit and a battery unit, wherein the box body 1 is a double-layer structure. A heat insulating layer is filled in an interlayer of the box body. When foods with certain temperature are arranged in the utility model, the heat can be effectively prevented from emitting out. Simultaneously, the tank bottom is provided with a heater. When the foods are gradually cooled after a long time, the heater works by the control circuit and thus the temperature of the foods is increased. The utility model solves the problem that the foods are easy to cool when people go out, and is convenient and practical.

Description

A kind of portable heat-insulation box

Technical field

The utility model relates to a kind of container, particularly a kind of portable heat-insulation box.

Background technology

Usually people are travelling outdoors, camp or all can relate to the problem of how to carry food when driving for a long time, generally can only select some bagged instant food and bottled drink etc., and these food often all are normal temperature or freezer storage, when edible, can not be fit to proprietary edible demand, especially in the entourage, the baby is arranged, when old man or patient or when going on a journey winter, more edible warm foods are wished in the capital, in addition, the problem that exists food to be incubated too in fast food express delivery industry, now generally be to reach the purpose that keeps food temperature by wrapping up simply with some insulation materials, but time long slightly back food still can cool off, thereby influences quality of food.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of temperature that can keep food for a long time, and the portable heat-insulation box that can heat food.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of portable heat-insulation box comprises casing, box sealing lid, control circuit and battery pack, is provided with inner bag in the described casing, is filled with insulating between casing and inner bag, also is provided with the heater that is electrically connected with control circuit and battery pack in casing.

As the utility model preferred embodiment, be provided with inner cap in the described box sealing lid, be filled with insulating therebetween.

As the improvement of the above-mentioned embodiment of the utility model, casing is provided with the utility outlets that can import external power supply outward.

The beneficial effects of the utility model are: because the utility model has added inner bag in the casing that has seal cover of splendid attire food, and between casing and inner bag stuffed heat insulated heat-insulation layer, can prevent effectively that like this fuel value of food from distributing, also at the bottom of case, be provided with heater simultaneously, when cooling off gradually through the long period, food heater work can be heated to food by control circuit, use when travelling or going out because this portable heat-insulation box is furnished with battery pack institute, and casing also can be provided with the utility outlets of external power supply outward, like this when this portable heat-insulation box uses in indoor or car, also can connect civil power or connect directly that cigar lighter uses in the car by the external power supply adapter, also can be the rechargeable battery pack charging simultaneously, convenient and practical.

The specific embodiment

Referring to figs. 1 through Fig. 4, the utility model is a kind of portable heat-insulation box, comprise casing 1, box sealing lid 2, control circuit and be chargeable storage group 3, be provided with inner bag 11 in the described casing 1, between casing 1 and inner bag 11, be filled with insulating 12, in casing 1, also be provided with the plane formula heater 4 that is electrically connected with control circuit and battery pack 3, be provided with inner cap 21 in the seal cover 2, be filled with insulating 22 therebetween, casing 1 outer utility outlets 5 and the display floater 6 that to import external power supply that be provided with, described sealing case lid 2 is rotatably connected by hinge 7 and casing 1, and by snap close 8 and casing 1 fastening, be provided with handle 9 outside the sealing case lid 2, on described display floater 6, be provided with power supply indicator 61, pre-thermal light 62, charging indicator light 63, three sections holding temperatures show 64, internal memory battery electric quantity indication 65, button 67 is set in insulation selection key 66 and preheating.

In the present embodiment, casing 1 and seal cover 2 all are made as double-decker, and all stuffed heat insulated heat-insulation layer in interlayer, can prevent effectively when putting into the food of uniform temperature that like this heat from distributing, because also be provided with battery pack 3 and control circuit in the casing 1, so when memory time, length caused food temperature to descend, control circuit makes heater 4 work that are located in the casing 1, heat food is with the heat of replenish lost, various index indicator lamps and button set on display floater 6 can help the user to understand the working condition of incubator, so that operate accordingly, sealing case lid 2 is connected on the casing 1 and with snap close 8 by hinge 7 and fastens, make incubator become as a whole, be convenient to arbitrarily move.
