The utility model is characterized in that the heating element is provided with a metal casing with the thermostat thereon corresponding to the position of the heating element; the heating element is provided with a heating wire; the metal casing can contain the heating element; a heat conductive layer is arranged between the incorporated metal casing and the heating element; the metal casing is copper casing; the metal casing is aluminum casing. The dry-burning protection electrical thermal bag of the utility model has simple structure, safety and reliability.
Description
Technical field
This utility model relates to a kind of heat-preserving equipment, is a kind of anti-dry electric warming bag specifically.
Background technology
Electric warming bag is a kind of heating, warming utensil that generally uses.Existing electric warming bag, generally by bag, be fixed on supply socket, the temperature controller on the bag and place the intravital heat generating member of bag to form.Wherein heat generating member is electrically connected with supply socket with lead, and temperature controller is located in the bag., the electric warming bag of this structure is because the caloric value of heat generating member is concentrated, and the temperature controller dip is in the intravital conductive fluid of bag, and its temperature control medium is a conductive fluid.When the temperature of heat generating member surpassed rated temperature, the intravital conductive fluid temperature of bag can further not improve, so temperature controller can accurately not survey the temperature of heat generating member, and the sensitivity of temperature controller monitoring is relatively poor, and heater circuit can not in time disconnect.Except causing electric warming bag to occur the dry combustion method phenomenon, when heat generating member touches bag, also can be because of the too high phenomenon that bag is burnt out of heat generating member temperature.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, safe and reliable anti-dry electric warming bag is provided.
Goal of the invention of the present utility model is achieved in that a kind of anti-dry electric warming bag, comprise bag, be located at the supply socket on the bag and be located at intravital temperature controller of bag and heat generating member, it is characterized in that: described heat generating member is provided with metal-back, temperature controller is located on the metal-back, and corresponding with the heat generating member position.
Described heat generating member is electrothermal wire heating's part.
Described metal-back is for containing the metal-back of heat generating member.
Be provided with heat-conducting layer between described metal-back and the heat generating member.
Described metal-back is that one is connected with heat generating member.
Described metal-back is the copper shell.
Described metal-back is an aluminum hull.
This utility model improves existing electric warming bag, and a metal-back is set outside heat generating member, and temperature controller is arranged on the metal-back, and by the conductive force of metal-back, the heat on the heat generating member can be delivered on the temperature controller fast.When the temperature of heat generating member has surpassed rated temperature, produce action by the temperature controller that is arranged on the metal-back, heater circuit is cut off, effectively prevent the phenomenon of electric warming bag dry combustion method.In addition,, therefore can be distributed to the heat of heat generating member fully on the conductive fluid, improve the efficiency of heating surface of electric warming bag because the heating surface of metal-back is long-pending bigger than heat generating member.
Description of drawings
Fig. 1 is the structural representation of this utility model most preferred embodiment.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
According to shown in Figure 1, anti-dry electric warming bag of the present utility model mainly is made up of bag 1, supply socket 2, temperature controller 3 and heat generating member 4, and wherein supply socket 2 is located on the bag 1, and 4 of temperature controller 3 and heat generating members are located at bag 1, and heat generating member 4 is the resistance wire heat generating member.Supply socket 2, temperature controller 3 and heat generating member 4 are connected in series.Heat generating member 4 is provided with metal-back 5, and this metal-back 5 can be to contain heat generating member 4 entirely, also can be half containing heat generating member 4.Can be that partition is connected between metal-back 5 and the heat generating member 4, also can be the one connection.In order to improve the heat conduction efficiency between metal 5 and the heat generating member 4, but between charges into heat-conducting layer, and this heat-conducting layer can be silicone grease or other Heat Conduction Material.In order to improve metal-back 5 thermal conduction effect in use, this metal-back 5 can be the copper shell, also can be aluminum hull.Temperature controller 3 is located on the metal-back 5, and corresponding with heat generating member 4 positions.Anti-dry electric warming bag of the present utility model, by heat conductive metal shell 5 is set on heat generating member 4, and temperature controller 3 is arranged on the metal-back 5, except the phenomenon that effectively prevents the electric warming bag dry combustion method, can also be distributed to the heat of heat generating member 4 fully on the conductive fluid, improve the efficiency of heating surface of electric warming bag.
