Abstract
The utility model discloses a kind of electrical bar with self-protection function; the first wire comprising Electrothermic wire and be connected with described Electrothermic wire and the second wire; also comprise thermal protector; described thermal protector is connected with described Electrothermic wire by the first wire; an encapsulating shell is provided with outside described Electrothermic wire; described encapsulating shell and described thermal protector are all placed in a shell, all filler are housed in described encapsulating shell and described shell.This utility model can control water temperature accurately, long service life, and convenient.
Description
Technical field
The utility model relates to a kind of electrical bar, especially a kind of electrical bar with self-protection function.
Background technology
Traditional electric heating bar is protected by external mechanical formula temperature detect switch (TDS); the shortcoming of mechanical temperature control switch needs to operate artificially; and each temperature disconnected and recover is all different; be not easy to control water temperature accurately; mechanical temperature control switch is external simultaneously, therefore its useful life is shorter.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide one can control water temperature accurately, long service life, uses the more convenient electrical bar with self-protection function simultaneously.
For achieving the above object; the utility model adopts following technical scheme: a kind of electrical bar with self-protection function; the first wire comprising Electrothermic wire and be connected with described Electrothermic wire and the second wire; also comprise thermal protector; described thermal protector is connected with described Electrothermic wire by the first wire; be provided with an encapsulating shell outside described Electrothermic wire, described encapsulating shell and described thermal protector are all placed in a shell, and described encapsulating shell and described enclosure are all equipped with filler.Thermal protector can disconnect and connecting circuit automatically, makes temperature more accurate.Encapsulating shell can protect electrical bar, and thermal protector is positioned at enclosure simultaneously, and it can be made to affect from external force, increase the service life, the filler be wherein equipped with has the effect of heat conduction.First wire is used for being connected external power source with the second wire, to realize the normal work of electrical bar.
Preferably, described thermal protector is TB02-BB8D thermal protector.
Preferably, the inner bottom part of described shell and the outer bottom of described encapsulating shell contact.
Preferably, interval is had between the inner bottom part of described shell and the outer bottom of described encapsulating shell.
More preferably, described filler is magnesium oxide, and magnesium oxide has good heat conduction function.
The beneficial effects of the utility model are as follows: this electrical bar can control water temperature accurately, not only easy to use but also useful life is longer, and its heat-conducting effect is also better simultaneously.
Accompanying drawing explanation
Fig. 1 is a kind of external view with the better embodiment of the electrical bar of self-protection function of the utility model.
Fig. 2 is a kind of enclosure structure chart with the better embodiment of the electrical bar of self-protection function of the utility model.
Fig. 3 is a kind of encapsulating shell cut-away view with the better embodiment of the electrical bar of self-protection function of the utility model.
Reference numeral: 1, Electrothermic wire; 2, thermal protector; 3, the first wire; 4, the second wire; 5, encapsulating shell; 6, shell; 7, filler.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1, Fig. 2 and Fig. 3; the utility model relates to a kind of electrical bar with self-protection function; the first wire 3 and the second wire 4 that its better embodiment comprises Electrothermic wire 1 and is connected with Electrothermic wire 1; also comprise thermal protector 2, this thermal protector 2 is TB02-BB8D thermal protector preferably.Thermal protector 2 is connected with Electrothermic wire 1 by the first wire 3, and be provided with an encapsulating shell 5 outside Electrothermic wire 1, encapsulating shell 5 and thermal protector 1 are all placed in a shell 6, have interval between the inner bottom part of shell 6 and the outer bottom of encapsulating shell 5.Filler 7 is all equipped with in encapsulating shell 5 and shell 6 inside, and this filler 7 is preferably magnesium oxide.
The utility model also comprises another kind of execution mode simultaneously, and namely the inner bottom part of shell and the outer bottom of encapsulating shell contact.
When electrical bar switches on power work, it temperature can rise because of heating, and after temperature reaches the protection value of thermal protector 2 setting, thermal protector 2 can disconnect automatically, cuts off circuit, plays a protective role.After the temperature of electrical bar drops to the recovery value of thermal protector 2 setting, thermal protector meeting automatic processing circuit, electrical bar recovers normal work.So heating provides heat repeatedly, thus realizes water temp. auto-control.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection range of the utility model claim.
