Abstract
The utility model discloses a safety protection device of an electric blanket, which comprises a temperature sensitive resistor, a slide rheostat, a phase inverter, a light-emitting diode, a relay, a triode, a power supply, a switch, a buzzer and a resistor. The temperature sensitive resistor, the slide rheostat, the phase inverter, the light-emitting diode and the relay are in series connection to the position of a base electrode of the triode through wires, and the buzzer is connected to the position of a collector electrode of the triode. The relay is used for controlling a heating circuit of the electric blanket, when the relay is powered on, the heating circuit of the electric blanket is opened at once, and the electric blanket is not heated any more. One end of the resistor 1 is connected to a positive electrode of the power supply, and the other end of the resistor 1 is connected to the base electrode of the triode. The safety protection device of the electric blanket has the advantages of being 1 simple to operate and convenient to use; and 2 low in cost and convenient for mass production.
Description
Technical field
The utility model relates to a kind of protector, and is particularly a kind of when electric blanket temperature is too high, breaks off the electric blanket heater circuit immediately, the electric blanket safeguard protection apparatus of reporting to the police simultaneously.
Background technology
Winter temperature is low, and some will electric blanket.Because the electric blanket quality problems, perhaps service time long, cause electric blanket in use, can appearance temperature too high, breaking out of fire threatens to people's the security of the lives and property.
Summary of the invention
The utility model problem to be solved is: to existing electric blanket in use may appearance temperature too high, and the phenomenon of breaking out of fire, and a kind of electric blanket protector is provided.
The electric blanket protector of the utility model; Comprise that thermo-sensitive resistor 1, slide rheostat 2, inverter 3, light-emitting diode 4, relay 5, triode 6, power supply 7, switch 8, buzzer 9, resistance 10 form, described thermo-sensitive resistor 1, slide rheostat 2, inverter 3, light-emitting diode 4, relay 5, be connected in series to the base stage place of triode 6 through lead, described buzzer 9 is connected on collector electrode place of triode 6; Described relay 5 is the heater circuits that are used for controlling electric blanket; Must be electric when relay 5, the heater circuit of electric blanket opens circuit immediately, and electric blanket no longer heats; Described resistance 10 1 termination powers 7 positive poles, a termination triode 6 base stages.
The utlity model has following advantage:
1. simple to operate, easy to use;
2. with low cost, be convenient to a large amount of productions.

Fig. 1 is the circuit diagram of the utility model.
Among the figure: thermo-sensitive resistor 1 slide rheostat 2 inverters 3 light-emitting diodes 4 relays 5 triodes 6 power supplys 7 switches 8 buzzers 9 resistance 10
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
In Fig. 1, a kind of electric blanket protector comprises thermo-sensitive resistor 1, slide rheostat 2, inverter 3, light-emitting diode 4, relay 5, triode 6, power supply 7, switch 8, buzzer 9, resistance 10 compositions; Described thermo-sensitive resistor 1, slide rheostat 2, inverter 3, light-emitting diode 4, relay 5, be connected in series to the base stage place of triode 6 through lead; Described buzzer 9 is connected on collector electrode place of triode 6, and described relay 5 is the heater circuits that are used for controlling electric blanket, when relay 5 gets; The heater circuit of electric blanket opens circuit immediately; Electric blanket no longer heats, described resistance 10 1 termination powers 7 positive poles, a termination triode 6 base stages.
Too high when electric blanket temperature, the thermo-sensitive resistor resistance diminishes, the voltage decreases of inverter input; When its voltage was low level, the inverter output voltage was a high level, at this moment; The light-emitting diode conducting, the heater circuit of electric blanket is broken off in relay work immediately; Triode is conducting also, and buzzer is sounded, and wakes the heavy sleeper.
