Abstract
The utility model discloses an adjustable electric heating device. The device is in a structure of double heating tubes and a joint soleplate. Four contacts of the electric heating tubes form a one-shaped arrangement, and shapes of the two electric heating tubes are respectively a star shape and a U shape. The utility model has the advantages of simple structure, and safe and convenient use.
Description
The utility model relates to a kind of electrothermal tube heater.
The electrothermal tube heater that generally uses at present is single tube double-contact structure, though this traditional electrical heat pipe heater has advantage of simple structure, electric current and temperature are unadjustable, uses inconvenient.
The purpose of this utility model provides a kind of electric current and temperature scalable, electrothermal tube heater easy to use.
The utility model comprises common electrothermal tube 1 and these electrothermal tube two end in contact 2, interface 2 ', this two interface passes substrate 3 respectively, fixedly connected with substrate 3 through insulating case 7, also be provided with earth point 6 and another electrothermal tube 4 on the substrate 3, two end interfaces 5 of electrothermal tube 4, interface 5 ' also pass substrate 3 is fixedlyed connected with this substrate through insulating case 8.
The power of electrothermal tube 1 is bigger, shape can for
Shape, to shorten straight length, the power of electrothermal tube 4 is less, and its shape can be U-shaped, and electrothermal tube 4 is included in the upper opening place of electrothermal tube 1, taken up space to reduce, the interface of two electrothermal tubes on substrate is in-line to be arranged, and it puts in order and is followed successively by: interface 2, interface 5, interface 5 ' and interface 2 ', earth point 6 interface 5 and interface 5 ' between.
The utility model is two heating tubes, many interfaces, the common backplane structure, an as long as external common change-over switches, just can select single electrothermal tube work or two electrothermal tubes to work simultaneously as required, the temperature and the electric current of this device can suitably be regulated,, just use safe ready so the utility model is simple in structure.
Accompanying drawing 1 is the utility model structural representation.
The power of the electrothermal tube 1 of the utility model embodiment is 1000W, and profile can
Shape or " U " shape, the power of electrothermal tube 4 is 700W, is common " U " shape electrothermal tube, electrothermal tube 4 is included in electrothermal tube 1 upper shed portion, the interface 2 of electrothermal tube 1, interface 2 ' with the interface 5 of electrothermal tube 4, interface 5 ' on substrate 3, be in-line to arrange, it is followed successively by interface 2 in proper order, interface 5, interface 5 ', interface 2 ', earth point 6 interface 5 and interface 5 ' between, substrate 3 can be made of metal materials such as aluminium alloys, is equipped with insulating case between this substrate and each interface, i.e. insulating case 7, insulating case 8.
