Offer the first spiral embedding slot 21 on the cylinder 2, the heater 1 along the first spiral embedding slot 21 on loaded on cylinder 2,
The heater 1 is also wound with the coil spring shape heat radiating structure 10 beyond the length of cylinder 2 in wherein one end of cylinder 2.In the electricity
In heater application process, terminals are made to be connected on power supply, to obtain electric energy from power supply.In the heater 1 of the present invention
Multiple Electrothermic wires 12 are provided with, and are to be connected respectively by respective wire 13 with power supply during the work of each Electrothermic wire 12
, so each Electrothermic wire 12 can realize independent work, so as to make electricity heating circle realize multistage heating, sectional temperature-controlled work
With this is favorably improved the temperature control scope of electric heating device, to improve the applicability of electric heating device.Meanwhile, pass through the present invention
Rational structure design, when manufacturing electric heater unit, can pre-processed unified specification heater 1, subsequently make as needed
The cylinder 2 of heater 1 and different size is assembled together, and thus the specification of heater 1 can be made to be fixed up, and makes heater 1
Production procedure more tends to standardization.In the electric heater unit of many specifications of manufacture high-volume, the debugging of machinery can be reduced, can be carried
The production efficiency of high electric heater unit, and then improve the production efficiency of enterprise.And so without being divided again each heater 1
Class, so that it may realize the management to heater 1, this can simplify the management process that electric heater unit constitutes component, reduce the pipe of accessory
What reason difficulty, the convenience of raising accessory management and reduction electricity heating were enclosed designs and develops cost.In the fabrication process, although heating
The work flow of body 1 is complex, but the efficiency of single process heater 1 is influenceed smaller by the length change of heater 1.Compared to point
Not Jia Gong plurality of specifications heater scheme, when can effectively shorten the manufacture of heater 1 using such structure design
Between, so as to greatly improve the manufacture efficiency of electric heater unit, and reduce the stock cost of electric heater unit.Heater 1 is another
One end can reduce the volume of whole electric heater unit around the structure for dressing up coil spring shape, to improve the suitable of electric heater unit
Use scope.Rationally, its service life is also very long for the electric heater unit overall construction design very simple of the present invention.In actual life
During production, 12 corresponding one sections of metal tubes 11 of an Electrothermic wire are at least made to be inlaid in the first spiral embedding slot 21 of cylinder 2
It is interior.When needing the adstante febre of cylinder 2, the Electrothermic wire 12 being connected on the correspondence position of metal tube 11 can be made to be connected with power supply, with
Electrothermic wire 12 is set to generate heat, the heat that then Electrothermic wire 12 is produced will be transmitted on cylinder 2.Generated heat by wire 13 with electricity
The reasonable Arrangement of silk 12, Electrothermic wire 12, can be according to the different wires 13 of connection when the cylinder 2 of different length is assembled respectively
To obtain the electric heater unit of corresponding heating condition, its structure design is very scientific and reasonable, it is possible to decrease the stock of electric heater unit
Cost.
It is the applicable performance of further lifting electrical heating device, as shown in Figures 4 to 6, the electricity on the basis of foregoing

It is interconnected together, and be also respectively formed with gap 30 between each cylinder 20, between cylinder 2 and adjacent secondary cylinder 20.
In the structure design, by connecting different wires 13 different Electrothermic wires 12 can be made to generate heat, in the adstante febre of Electrothermic wire 12,
Temperature can be interrogated and be transmitted to fastly on corresponding cylinder 2 or secondary cylinder 20, so that cylinder 2 or secondary cylinder 20 generate heat.Pass through
Such structure design, can make that the heating of cylinder 2, each cylinder 20 is separate with not generating heat, and it can make cylinder 2 and each time
Cylinder 20 generates heat simultaneously, again wherein one or more cylinders can be made individually to generate heat.Just can be real so on an electric heater unit
Now control, Discrete control, heat stepwise, sectional temperature-controlled purpose respectively.This is favorably improved the accuracy of hot flow path temperature control, with
And improve the crudy of product.When electric heater unit is applied, can arbitrarily it adjust according to actual needs, use is very flexible,
Applicability is more preferable.Meanwhile, gap 30 is respectively formed between each cylinder 20, between cylinder 2 and adjacent secondary cylinder 20, can be kept away
Exempt from each cylinder and occur heat conduction each other, so that the work of each cylinder is more independent, would not be deposited between so each cylinder
In office what connection disturbs, to avoid the performance of electric heater unit from being affected.In said structure, connect with each Electrothermic wire 12
Wire 13 greater concentration of management has been obtained by joint protective component 15, so, the space that can reduce electric heater unit is accounted for
Consumption, reduces the volume of product, and can also reduce the arrangement difficulty of wire, and improve the convenience of TOP-TIP assembling with
The efficiency of assembling, this helps to reduce the assembly cost of whole system.It is single although the work flow of heater 1 is complex
The efficiency of secondary processing heater 1 is influenceed smaller by heater length change, compared to the side of the heater 1 of processing plurality of specifications respectively
Case, the manufacturing time of heater 1 can be effectively shortened using such structure, so as to greatly improve the manufacture of electric heater unit
Efficiency, and reduce the stock cost of electric heater unit.After electric heater unit is completed, each cylinder 2 can be generated heat
The effectively position-limiting action of body 1, makes the relative position between cylinder 2 and cylinder 2 keep constant, can so improve electric heater unit
Itself precision.And the whole structure with Discrete control and heat stepwise can be just arranged on by electric heater unit by once mounting
In TOP-TIP, this can reduce the installation difficulty of electric heater unit, moreover it is possible to ensure the installation accuracy of electric heater unit, improve
The reliability of product.Because the electric heater unit with Discrete control and heat stepwise during fabrication, exists precision controlling
In qualified orientation, it, which is installed in TOP-TIP, will not change the precision of electric heater unit.Therefore, electric heater unit
Installation is influenceed smaller by operative's ability, helps to ensure that the performance of TOP-TIP, and make every batch
TOP-TIP quality is more unified.Because electric heater unit component of the invention is less, and each heating section is to be firmly attached
Together, the Classification Management difficulty of workman can be so reduced, the convenience of management is improved.The electric heater unit knot of the present invention
