in the figure, 1 is a bag body, 2 is a heat preservation material layer, 3 is a heating sheet, 4 is a USB plug, 5 is an opening and closing zipper, 6 is a shoulder strap, and 7 is a hand strap.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the utility model is a but external power supply's heating package, including inclusion 1, this inclusion 1's inside is equipped with the cavity, inner wall or outer wall at inclusion 1 are equipped with insulation material layer 2, can play the heat preservation effect the same with similar insulation package through this insulation material layer 2, more importantly, still imbed the piece 3 that generates heat between the inner wall of inclusion 1 and outer wall, be connected this piece 3 that generates heat and USB connector 4 electricity, be used for inserting the power through USB connector 4 by the piece 3 that generates heat, and then make the heating circuit of the piece 3 that generates heat switch on, mobile power source such as the treasured that charges that generally can adopt the mainstream on the market passes through the USB connector and supplies power to the piece 3 that generates heat, be about to electric energy conversion for heat energy, on inclusion 1 insulation material is to its heat retaining basis, heat it simultaneously. Preferably, for the convenience of carrying, a back strap 6 and a hand strap 7 can be further arranged on the bag body 1, and as shown in fig. 1 in particular, the back strap 6 and the hand strap 7 have similar structures with the similar thermal insulation bags.

In the embodiment, the heating plate 3 is additionally arranged between the inner wall and the outer wall of the bag body 1, the USB plug 4 is connected with a power supply, the heating plate can be powered by using the currently widely used charger product, and then the heating plate 3 is used for continuously heating to supplement heat to the interior of the bag body, so that the heating and heat preservation effects are achieved, and the heat preservation time of the bag body 1 is effectively prolonged; and based on the thought in this embodiment, can process the inclusion into the size of variation in size, can be used to each field such as trade company takeaway delivery, individual meal carry.

According to the utility model discloses a further embodiment, for convenient use, similar with like insulation bag structure, still can add the annular zip fastener 5 that opens and shuts on the side of inclusion 1, conveniently open and shut inclusion 1 through this zip fastener 5 that opens and shuts and put the meal and get the meal promptly, be convenient for heat conduction simultaneously, can be with foretell generate heat piece 3 design for two, with two generate heat piece 3 imbed respectively between the inside and outside wall of inclusion 1 upper portion and lower part, the meal of intracavity in the inclusion is heated through upper and lower two-way promptly, heat conduction speed has not only been promoted, more can promote the homogeneity of heating. Further, the heat insulation material layer 2 can also be embedded between the inner wall and the outer wall of the bag body, the heat insulation material layer 2 is annularly arranged on the side surface of the bag body 1, and the heat insulation material layer 2 and the heating sheet 3 can be fixed in a sewing mode.

Based on the structure described in the above embodiments of the present invention, the most important purpose of the present invention is to heat and keep the heat for food, people take the prepared hot food to have a meal outdoors, or students take the hot lunch box to go to school, or office workers take the hot lunch box to go to work, and take out for delivery, etc., how to keep the heat of food, as long as the power is connected. The simplest and most convenient is that external power cord adopts the USB interface, and it is just right to join in marriage a treasured that charges, and is very convenient, as long as it has the electricity to charge the treasured, connects to charge the treasured and just can keep the original heat degree of food always, and the effect is very good. Compared with the existing heat preservation bag without a heat source, the heat preservation bag can really play a role in heating and heat preservation. The heat preservation bag without a heat source can not continuously preserve heat of food, the temperature of the food is lower and lower, and the cooked rice becomes cold after the food is heated for a long time. The heating bag which can be externally connected with the power supply can keep warm for food as long as the heating bag can be connected with the power supply. For cold food, the external power supply connecting wire can heat and preserve heat for the food as long as the external power supply connecting wire is communicated with the power supply. Therefore, the utility model can achieve the effects of heating and continuously keeping the heat degree as long as the power is switched on no matter the hot food or the cold food is eaten.
