Brief description of the drawings
Figure 1 shows that the structural representation of the metal embedded heater that the utility model one embodiment provides.
Detailed description of the invention
As shown in Figure 1, the metal embedded heater that the present embodiment provides comprises metal sleeve 1, heater strip 2 and temp.-sensing wire 3.On metal sleeve 1 sidewall, have along metal sleeve 1 length direction and extend to the opening 11 of 1 two end faces of metal sleeve.And there is at the lateral wall of metal sleeve 1 heating tank 12 that multistage is interconnected, be also provided with temperature-sensitive groove 13 in a side of heating tank 12.Heater strip 2 is embedded to be fixed in heating tank 12.Temp.-sensing wire 3 enters along opening 11, and is fixed in temperature-sensitive groove 13, detects in real time the temperature of metal sleeve 1.
The metal embedded heater that the present embodiment provides is offered the opening 11 that is communicated with upper and lower end face on the length direction of metal sleeve 1, makes metal sleeve 1 be open state.Nozzle is sheathed to be fixed in metal sleeve 1, in the time that heater strip 2 heats metal sleeve 1, and metal sleeve 1 expanded by heating.Metal sleeve 1 after expansion packs tightly nozzle and nozzle close contact, has improved the heating effect to nozzle.In the present embodiment, metal sleeve 1 adopts metallic copper to make.But the utility model is not limited in any way this.
And in the time that heater damage maybe needs to change nozzle, metal sleeve 1 need be separated with nozzle.The closed sleeve of traditional sidewall, metal sleeve 1 is difficult to separate with nozzle.And the metal embedded heater that the present embodiment provides is when needs separate metal sleeve 1 with nozzle, stop the heating of heater strip 2 to metal sleeve 1, cooled metal sleeve 1 shrinks, and has certain space between metal sleeve 1 and nozzle.In this simultaneously, utilize separator (as Circlip tongs) to act on opening 11, the aperture of enlarged opening 11, thereby by nozzle from metallic sheath, take out in 1.In other embodiment, be better fixedly separated device, also there are two semicircular arc through holes at two sidewalls of opening 11.Two pliers of Circlip tongs can be fixed in these two through holes, facilitate enlarged opening 11.
Because the size of opening 11 not only has influence on the complexity that nozzle separates with metal sleeve 1, also have influence on the heating effect of metal sleeve 1 to nozzle simultaneously.Opening 11 is larger, and metal sleeve 1 more easily separates with nozzle; And that nozzle is exposed to the surface area at opening 11 places is also larger, just poorer to the heating effect of nozzle.Therefore,, for realizing both balances, the radian that is arranged on metal sleeve 1 perspective plane upper shed 11 is vertically not more than 20 degree.
