Abstract
The utility model relates to an electric heating tube with a built-in thermal fuse body; the electric heating type soymilk machine is suitable for liquid heating household appliances, particularly a household soymilk machine, mainly comprises an electrode lead, an insulator, a nut, a thermal fuse, a stainless steel tube and an electric heating wire, and has the advantages of high reliability, stable fusing temperature value, quick temperature response, simple structure, low cost and the like compared with the prior art.
Description
Technical field:
The utility model relates to a kind of electrothermal tube with built-in thermal fuse-link, is suitable for using on liquid heat class household electrical appliance, the particularly household soy milk machine.
Background technology:
At present, electrical heating elements, particularly electric heating tube are widely used, it have electric conversion efficiency height, thermal inertia little, be convenient to advantage such as little in light weight, sanitation and hygiene of control, volume, thereby to be widely applied at liquid heat class domestic appliance, in particular be on the household soy milk machine.But in use, after being heated liquid and boiling dry, the circuit of electrothermal tube often still is in closure state, thereby produces high temperature, ignites to be heated liquid container or contiguous inflammable object, causes fire.
Summary of the invention:
The purpose of this utility model provides a kind of electrothermal tube with built-in thermal fuse-link, and it can overcome the deficiencies in the prior art.
The utility model is to realize like this, it mainly is made up of contact conductor, insulator, nut, thermal fuse-link, stainless steel tube, heating wire, wherein, the two ends of heating wire connect thermal fuse-link, contact conductor successively, insulator, nut and stainless steel tube connect and are enclosed within the outside of thermal fuse-link and heating wire successively, and insulator, nut are between contact conductor and thermal cut are stopped.
The utility model compared with prior art has reliability height, fusing-off temperature value stabilization, fast, simple in structure, the low cost and other advantages of temperature response.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Embodiment:
As shown in Figure 1, the utility model mainly is made up of contact conductor 1, insulator 2, nut 3, thermal fuse-link 4, stainless steel tube 5, heating wire 6, wherein, the two ends of heating wire 6 connect thermal fuse-link 4, contact conductor 1 successively, insulator 2, nut 3 and stainless steel tube 5 connect and are enclosed within the outside of thermal fuse-link 4 and heating wire 6 successively, and insulator 2, nut 3 are between contact conductor 1 and thermal fuse-link 4.During work; electric current is by heating wire 6; heating wire 6 heatings also make the stainless steel tube 5 peripherad liquid heat that are heated; because the effect of liquid; the temperature of stainless steel tube 5 and even heating wire 6, thermal fuse-link 4 can not surpass 100 degree Celsius; but when liquid constantly is heated, evaporates and reduces; and when liquid level is lower than the minimum point of stainless steel tube 5; the temperature of stainless steel tube 5, heating wire 6, thermal fuse-link 4 sharply rises; when temperature reaches a design temperature; thermal fuse-link 4 enters off-state, cuts off heating power supply, thereby reaches the purpose of heat protection.
