Vehicle-mounted heating bag

Abstract

The invention discloses a vehicle-mounted heating bag and relates to the field of heating bag structures. The vehicle-mounted heating bag comprises a bag body; a sealing opening is formed in the bag body; a power supply base is arranged at one end, opposite to the opening, of the bag body; a coupling vehicle-mounted power supply connector is arranged on the power supply base; a controller is arranged in the power supply base; the bag body is made of a flexible material and sequentially comprises a waterproof outer layer, a heat insulating layer, a heat conducting layer and a waterproof inner layer from outside to inside; the heat conducting layer is made of thermally conductive silica gel; heating coils connected with the power supply base are respectively arranged on two sides, relative to the sealing opening, of the bag body; the heating coils are arranged in the heat conducting layer and are opposite in position; inwards-raising structures are separately arranged at positions, corresponding to the heating coils, in the bag body and are annular raising structures; the middles of the annular raising structures are of inwards-concaved cambered surfaces; a plurality of suckers are uniformly arranged on the raising structures; a temperature sensor is arranged in each raising structure; the controller controls the opening or closing and passing current of the heating coils according to input signals of the temperature sensors. By arranging the flexible heating bag with heat insulation and quick heating, the vehicle-mounted heating bag disclosed by the invention has the advantages of convenience in carrying, no occupation of space, convenience for placement of bag heating objects or food with different shapes, capability of being used in a carriage and the like.

Description

technical field [0001] The invention relates to the field of heating bag structures, in particular to a vehicle-mounted heating bag. Background technique [0002] Vehicle-mounted incubators are mainly used for carrying refrigerated food or keeping food warm, such as carrying food, tea, beverages, etc. during travel.
