Abstract

The utility model provides a heat-preserving bag comprising a bag wall. A heat-preserving layer and an electric heating element are arranged in the bag wall; and the electric heating element is connected with an USB interface by a lead. The heat-preserving bag can achieve the heat-preservation function as the heat-preserving layer is provided; as the heat-preserving bag is connected with the USB faucet for heating, thus having low power consumption; no other electrical appliances such as a transformer and the like are needed; and the USB interface of the heat-preserving bag is directly pluggedin the USB faucet when heating is needed, therefore, the heat-preserving bag is very convenient and reduces production cost.

Description

A kind of insulation bag

Technical field

The utility model relates to the insulation bag.

Background technology

Insulation bag major part on the existing market has all designed insulating and has been incubated, but often have only heat insulation function and do not have the temperature function of adding, the slightly long cooling that a bit unavoidably can be slowly of time that food is deposited, and often price comparison costliness is wrapped in the insulation of the high high insulating effect of quality.Also have on the market by having circuit socket and electric heating element, have the insulation bag that can add temperature function, but it need use the bigger power supply of civil power equipower, to some specific place incompatibilities, and consumption of power is relatively large.

Summary of the invention

Technical problem to be solved in the utility model provides the insulation bag that a kind of power is little, easy to use, not only can be incubated but also can heat.For this reason, the utility model by the following technical solutions: it comprises the bag wall, is provided with heat-insulation layer and electric heating element in the described bag wall, and described electric heating element is connected with USB interface by lead.

By above technical scheme, the utility model is provided with heat-insulation layer, can play heat insulation effect, it is by the heating that links to each other with the USB socket, consumption of power is low, need not the electrical equipment of other voltage transformer and so on, directly USB interface of the present utility model is inserted in the USB socket when needing heating to get final product, very convenient, and reduced the cost of making.

The specific embodiment

The utility model is the food insulation heat packs of being heated by the USB interface power supply, and the user can utilize the USB low potential source interface of particular place to heat for inclusion inside for power supply source, and design simultaneously has heat-insulation layer, to improve insulation and heats.

With reference to accompanying

drawing

1,2,3.The utility model comprises inclusion, and inclusion is formed at the bottom of wrapping wall and clad, bag.The utility model is bag wall 1, clad 2 and the bag end on four limits all around, all is made up of inwall 3 and outer wall 4, is provided with heat-insulation layer 5 between inwall 3 and the outer wall 4, also is provided with handle 6 on the clad 2.In the present embodiment, bag all is provided with heat-insulation layer at the bottom of wall, clad and the bag, certainly for cost-cutting, and also can only the bag wall on four limits be provided with heat-insulation layer all around.

In the present embodiment, heat-insulation layer 5 can certainly adopt other materials by expanded material or compound insulating material or metal wool (space wadding) material formation, can play heat insulation effect and get final product.The electric heating element of establishing in heat-insulation layer and the utility model cooperatively interacts, in heating is arranged, insulation is arranged outward, can improve heats greatly to food.Through experiment, the utility model can heat the temperature of food and remain on more than 60 degree.

The utility model has been installed one or more electric heating elements 7 between the inwall 3 of all around bag wall 1 and heat-insulation layer 5, electric heating element 7 is connected with USB interface 9 by extending to the outer lead 8 of bag wall, and in the present embodiment, electric heating element 7 is four.Inwall 3 has adopted heat conduction waterproof fabrics preferably, can be passed in the bag by actv. to ensure heat that heat element was sent.In the present embodiment, electric heating element is two heating films that PET is a material, and links to each other with USB interface in parallel.Adopting PET is that the reason of the heating film of material is that its material softness, waterproof, anti-high temperature, insulativity are also very good.Electric heating element 7 links to each other with USB interface 9 by lead 8 can allow heat element work after the energising, and inside of the present utility model is heated.

The utility model can also be parallel with the LED light 10 of a band current-limiting resistance simultaneously in circuit, whether the heating part of checking USB insulation bag that so just can be real-time is in normal working, adopts LED to have as the advantage of indicator lamp: electric quantity consumption is low, working stability, long service life etc.

The lead 8 of drawing from electric heating element 7 and LED light 10 is connected to USB interface power supply 9 by a pull-type USB connector 11 of list.Single pull-type USB connector 11 be one at lead design-calculated folk prescription to from winding apparatus, lead can be pulled out in this device during use, the time spent lead can not bounce back in this device automatically.

In the present embodiment, the Bao Biyu bag end, the common package space of depositing common cutlery box that forms of clad use to make things convenient for the working clan.In fact, the utility model also can manufacture plurality of specifications adapting to user's different needs, as puts the little insulation bag of warm pot foods, or the big insulation bag eaten of one family etc.

All be provided with the elastic frenulum 12 of placing tableware on four angles of the utility model inwall, can be used for assigning the instruments of having a dinner such as soupspoon and chopsticks.This elastic frenulum also can be designed as slash pocket, and playing fixedly, the effect of tableware gets final product.

The utility model has the advantage of: 1) the utility model has adopted the USB interface low-voltage power supply, environmental protection, It is again practical and convenient to economize on electricity. 2) the utility model has been installed LED light at inclusion, can allow user one Order checks whether the insulation bag is in running order with being clear. (3) the utility model is owing to adopt USB low pressure to supply Electricity, power limited all needs higher requirement to exothermic material electric conversion efficiency, thermal conductivity etc., therefore originally The heating of utility model has adopted the PET material to make, and its heating is stable, waterproof, anti-high temperature, insulation The property splendid, effectively guaranteed the use safety of insulation bag.

The utility model be for the white collar clan go to work designed, during use, can be with food (as carrying lunch box) After taking the job site to, with the energising of this insulation bag, allow it slowly heat, noon just can be had and carry Good to eat warm food, very convenient to use.
