Abstract
An electric heating tube comprises a casing and a heater which is arranged in the casing and is connected with external electricity. The utility model is characterized in that the heater has an inner layer and an outer layer, wherein an insulated heat conducting layer is arranged between the outer layer and the inner layer, the outer layer is arranged between the casing and the insulated heat conducting layer, the casing and the insulated heat conducting layer are flexible soft material members, and the casing is insulated heat conducting material member, the outer layer is entwined with the insulated heat conducting layer. The utility model has the advantages of high adaptability in installment environment and high heating efficiency.
Description
Technical field
The utility model relates to firing equipment, particularly relates to a kind of electric heating tube.
Background technology
Existing electric heating tube, generally by housing, be arranged at the heating wire in the housing and be filled in housing and heating wire between the insulating packing layer.Be electrically connected with extraneous by the heating wire two ends, make the heating wire heating.The material of insulating packing layer is a heat-conducting medium, and the heat that heating wire produces can be delivered on the housing through the insulation packing layer, thereby reaches the purpose of heating., existing housing is rigid material spare, must mounting groove be set according to the size of electric heating tube itself when electric heating tube is installed.The electric heating tube of this structure in some specific occasions, the situation of bending etc. occurs after installing such as the size of mounting groove uncertain or electric heating tube when electric heating tube is installed, existing electric heating tube can not satisfy it and use needs.Therefore, existing electric heating tube structure still remains to be improved.
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, electric heating tube that the efficiency of heating surface high strong to installation environment adaptability is provided.
Goal of the invention of the present utility model is achieved in that a kind of electric heating tube, comprise housing and be located at the interior heating wire of housing, heating wire is electrically connected with extraneous, it is characterized in that: described heating wire is divided into skin and internal layer, be provided with the insulating heat-conductive layer between skin and the internal layer, skin is located between housing and the insulating heat-conductive layer, and housing and insulating heat-conductive layer are flexible soft material spare.
Described housing is an insulating heat-conduction material spare.
Described skin is wrapped on the insulating heat-conductive layer.
The utility model improves existing electric heating tube, replaces existing stiff case with soft housing and insulating heat-conductive layer.Because housing and insulating heat-conductive layer are flexible soft material spare,, therefore improved the adaptability of electric heating tube greatly to installation environment so in the process that electric heating tube is installed, the user can install electric heating tube according to being provided with of mounting groove.Simultaneously, because housing and insulating heat-conductive layer are insulation material layer, heating wire can be arranged to double-deck form, thereby has strengthened the efficiency of heating surface of electric heating tube.
Description of drawings
Fig. 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
According to shown in Figure 1, electric heating tube of the present utility model comprises housing 1 and heating wire, and heating wire is located at the inside of housing 1, and heating wire is electrically connected with extraneous.Wherein, heating wire is divided into skin 2 and internal layer 3, is provided with insulating heat-conductive layer 4 between skin 2 and the internal layer 3.Outer 3 are wrapped on the insulating heat-conductive layer 4, and outer 2 are located between housing 1 and the insulating heat-conductive layer 4.In order to improve the adaptability of electric heating tube to installation environment, housing 1 and insulating heat-conductive layer 4 are flexible soft material spare.Because heating wire skin 2 is wrapped on the insulating heat-conductive layer 4, so housing 1 is an insulating heat-conduction material spare.Electric heating tube of the present utility model is because housing 1 and insulating heat-conductive layer 4 are flexible soft material spare, so in the process that electric heating tube is installed, the user can install electric heating tube according to being provided with of mounting groove, has improved the adaptability of electric heating tube to installation environment greatly.Because housing 1 is insulation material layer with insulating heat-conductive layer 4, heating wire can be arranged to the double-deck form of skin 2 and internal layer 3, has strengthened the efficiency of heating surface of electric heating tube.
