Abstract

The utility model discloses a foldable thermos bag, which comprises a bag cover, a bag body and a bag bottom. The bag body is connected with the bag cover by the aid of a zipper; the bag body and the bag bottom are connected fixedly to form a structure with a cavity; the bag body is formed by sequentially overlapping an outer layer, an heat insulating layer, a heating layer and an inner layer; a spiral spring is arranged between the outer layer and the heat insulating layer; the heating layer is formed by arranging synthetic fiber cloth between two nonwoven layers; conducting yarns are evenly distributed on the synthetic fiber cloth in a sewn manner to form a resistance loop with two electrodes; a battery bag carrying a power box is arranged on the bag cover; and the power box is connected with the two electrodes by the aid of leads to form a heating control circuit. As the structure is adopted, the bag body not only can be compressed and folded to reduce necessarily occupied space and facilitate carrying, but also is controllable in temperature, and can be heated and kept warm at any time and in any places, thereby meeting the need that heating and heat insulation can also be performed in a field and areas without commercial power, facilitating life of people and benefiting health.

Description

Collapsible thermal protective aid

Technical field

The utility model relates to a kind of thermal protective aid, relates in particular to a kind of collapsible thermal protective aid.

Background technology

Development along with society, great variety has also taken place in people's quality of life, in out on tours, mountain-climbing, pleasure trip on foot, during outdoor activities such as exploration, all need the food that is prepared in advance, foods such as drink are incubated, it is required that common way is to use thermal protective aid can partly satisfy for it, but thermal protective aid in the past only has heat insulation function and does not have heating function, if the resting period is long, food in the thermal protective aid, foods such as drink will cool off, thereby health and quality of life caused influence, in order to address this problem, so just there is the dealer to develop heatable thermal protective aid, and the exothermic body of this heat tracing bag adopts the thermo electric material of resistor wire and so on mostly, not only fractures easily and damages, and service life is short, it is low that heat is imitated conversion, poor stability, and only be applicable to the place that conveniently obtains civil power, just can't carry out heat tracing in the place of no civil power.Simultaneously bag can not fold, and it is big to take up room, and carries very inconveniently, thereby practicality is little.

The utility model content

The purpose of this utility model just provides that a kind of folding is anti-rubs, and saves the space, is easy to carry, and is both artistic and practical, safety factor height, long service life, and the collapsible thermal protective aid that can heat whenever and wherever possible.

For achieving the above object, the purpose of this utility model realizes by following technical proposals, a kind of collapsible thermal protective aid, comprise pkt. flap, the bag and the bag end, bag is connected by slide fastener with pkt. flap, be connected and fixed formation to have the structure of cavity at bag and bag at the end, described bag is by skin, thermal insulation layer, heating layer and internal layer and be formed by stacking in proper order according to this, between skin and thermal insulation layer, be provided with coil spring, described heating layer is to be provided with synthetic fiber cloth between the two-layer nonwoven, adopting the sewing mode to be evenly equipped with conductive yarn on synthetic fiber cloth constitutes to have the resistance loop of two electrodes, be provided with the battery bag above the described pkt. flap, at the mid-power pack that is placed with of battery bag, described power pack is connected to form the heating control circuit by lead and two electrodes.

Preferred scheme is, is that nylon cloth one surface is provided with waterproofing coating according to skin described in the utility model, and another surface is provided with the structure of PVC coating.

Preferred scheme is to be the composite structure of hot melt adhesive film and metallic film according to thermal insulation layer described in the utility model.

Preferred scheme is to be that the cross section is pipe strip, flat-shaped or rectangular-shaped steel according to coil spring described in the utility model, and in this steel appearance zinc coating to be set.

Preferred scheme is, is to be coated with silverskin or the nickel film is made by polyamide or polypropylene filament surface according to conductive yarn described in the utility model, and its fiber number is 75D-1000D, every meter 0.5 Ω-120 of resistance value Ω.

Preferred scheme is to be the composite structure of stainless steel wire screen cloth and metallic film according to internal layer described in the utility model.

Preferably scheme is, is provided with chargeable ferric phosphate lithium cell and controller according to power pack described in the utility model inside, and box is provided with indicator lamp, charging socket and function key, its output voltage 6V-12V outward.

Preferred scheme is to comprise cylinder, cuboid or square according to thermal protective aid shape described in the utility model.

The utility model has the advantages that, because bag has adopted coil spring and cloth matter exothermic body, its flexural strength height, be difficult for pressurized deformation, not only can compress folding, reduce required occupation space, be easy to carry, both artistic and practical, the safety factor height, and Controllable Temperature, the heat efficiency height is heated evenly, temperature retention time is long, and heat tracing whenever and wherever possible, to satisfy open-air and not have the needs that the civil power area also can heat tracing, make things convenient for people's life, helped health.
