Description
Technical field
The utility model relates to heater commonly used in a kind of life, particularly a kind of electrically heated rod device.
Background technology
Existing common heating rod, normally do not have lamp or ordinary lamps, and do not have safety protective circuit.Under these circumstances, the difficult situation of heating rod when work of controlling of user increased danger coefficient.At present, thermistor is a kind of circuit original paper of technology maturation, have that volume is little, energy consumption is low, long service life, high sensitivity, controllability are strong, environmental protection and plurality of advantages such as sturdy and durable, be applied in a lot of industries and field and obtained good effect.But also be not applied on the common heating rod.
Summary of the invention
For solving the problems referred to above that prior art exists, the utility model will design a kind of electrically heated rod device with safeguard protection.
To achieve these goals, the technical solution of the utility model is as follows: a kind of electrically heated rod device, comprise heating rod, cable and plug, described heating rod comprises caput and excellent body, junction at caput and excellent body is inlaid with thermistor, be separately installed with electromagnetic relay and LED lamp on the top of caput, the temperature-adjusting circuit and the LED display circuit of thermistor control is housed in heating rod inside; Temperature-adjusting circuit, output that the input of described electromagnetic relay connects thermistor control are connected to the LED display circuit; It is the excellent body of high thermal conductivity alloy material preparation that described excellent body is adopted.
The temperature-adjusting circuit of thermistor described in the utility model control comprises thermistor and with the fixed value resistance of making comparisons.
One end of thermistor described in the utility model with after LED lamp and fixed value resistance are connected, is connected with an end of heating rod and an end of AC power respectively successively again; The other end of thermistor is connected with the other end of heating rod and an end of electromagnetic relay respectively, and the other end of electromagnetic relay is connected with the other end of AC power.
LED lamp described in the utility model is a red LED lamp.
Compared with prior art, the utlity model has following beneficial effect:
1, the electrically heated rod device of the utility model design is identical with common electrical heating rod device on external form, but in electric heating dress bar device inside the temperature-adjusting circuit and the LED display circuit of thermistor control is housed.When heating rod places when being heated liquid and using, Closing Switch is connected circuit, and red LED lamp is bright, the heating rod operate as normal.When if the temperature that heating rod is in empty burning state or is heated liquid surpasses limiting temperature, the circuit automatic disconnection, the LED lamp extinguishes, and guarantees that Yin Wendu sharply raises and produces safety problem.
2, daily electrically heated rod is generally shorter useful life, main because of the increase along with practical number of times, the degree of excellent body oxidation by air strengthens, and surperficial electric wire is very fast aging, this just makes people need frequent change heating rod, both uneconomical also not environmental protection.And the utility model timely open circuit in heating process, and rod effectively increases its useful life as the high thermal conductivity alloy material preparation, makes people more muchly to its effective utilization, reduced the pollution to environment.
3, the utility model shows the real-time working state of whole electrically heated rod device by display circuit, brings the design of a hommization to everybody.
Description of drawings
2 in the total accompanying drawing of the utility model, wherein:
Fig. 1 is an electrically heated rod apparatus structure schematic diagram.
Fig. 2 is the circuit diagram of electrically heated rod device.
Among the figure: 1, caput, 2, excellent body, 3, thermistor, 4, electromagnetic relay, 5, the LED lamp, 6, cable, 7, plug, 8, fixed value resistance.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.Shown in Fig. 1-2, a kind of electrically heated rod device, comprise heating rod, cable 6 and plug 7, described heating rod comprises caput 1 and excellent body 2, junction at caput 1 and excellent body 2 is inlaid with thermistor 3, be separately installed with electromagnetic relay 4 and LED lamp 5 on the top of caput 1, the temperature-adjusting circuit and the LED display circuit of thermistor 3 controls is housed in heating rod inside; Temperature-adjusting circuit, output that the input of described electromagnetic relay 4 connects thermistor 3 controls are connected to the LED display circuit; Described excellent body 2 is excellent bodies 2 of high thermal conductivity alloy material preparation.The temperature-adjusting circuit of described thermistor 3 controls comprises thermistor 3 and with the fixed value resistance 8 of making comparisons.One end of described thermistor 3 with after LED lamp 5 and fixed value resistance 8 are connected, is connected with an end of heating rod and an end of AC power respectively successively again; The other end of thermistor 3 is connected with the other end of heating rod and an end of electromagnetic relay 4 respectively, and the other end of electromagnetic relay 4 is connected with the other end of AC power.Described LED lamp 5 is red LED lamp.
Operation principle of the present utility model is as follows: the rod of heating rod is as the high thermal conductivity alloy material preparation, and LED lamp 5 can and extinguish the operating state of coming display circuit by Chang Liang.Heating rod rod body 2 is the heating major part, adopts the resistance wire nano junction that impedance is big, heat production is fast of energy saving to be fired into, and thermistor 3 can directly not contact with being heated liquid, can not produce leaky.This design is with thermistor 3 temperature-adjusting circuits, and electromagnetic relay 4 is protection control automatically.When placing to be heated, heating rod stirs mains switch when liquid uses, put into water, thermistor 3 is started working, resistance changes, circuit is transferred to electromagnetic relay 4 with signal, the LED display circuit that electromagnetic relay 4 can be controlled heating rod caput 1 changes, and shows the operating state of heating rod.When if the temperature that heating rod is in empty burning state or is heated liquid surpasses limiting temperature, the circuit automatic disconnection, LED lamp 5 extinguishes, and guarantees that Yin Wendu sharply raises and produces safety problem.If thermistor 3 operate as normal, temperature does not reach requirement, and resistance changes minimum, and electromagnetic relay 4 operating circuits receive undesirable circuit signal, and the LED lamp 5 of heating rod caput 1 still shows red.
Be heated when using in the liquid when heating rod is put in, the order that electromagnetic relay 4 operating circuits control LED lamp 5 changes is: Chang Liang--extinguish.
