Description
Technical field
The utility model belongs to the control device technical field, relates in particular to a kind of sound control switch device.
Background technology
The existing insulating pot of blowing a whistle can be pointed out people by sounding when water is held, but powered-down is still by manually operating, if people nearby or not do not hear, again or the user be handicapped people, timely powered-down then, therefore the existing insulating pot of blowing a whistle is safe not enough, energy-conservation.
Summary of the invention
The utility model is exactly at the problems referred to above, provides a kind of and is used with the insulating pot of blowing a whistle, safer, environmental protection, sound control switch device energy-conservation, easy to use and simple in structure.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises casing, its structural feature casing is provided with socket, switch, microphone, indicator light and potentiometer knob, be provided with ATD in the described casing, the input of ATD links to each other with microphone by amplifying circuit, the output of ATD is leaded up to first resistance and is linked to each other with dc power anode, another road of the output of ATD links to each other with transistor base by second resistance, transistor collector links to each other with dc power anode, transistor emitter links to each other with relay control end one end by described switch, the relay control end other end links to each other with dc power cathode, and the controlled end of relay is connected and linked to each other with civil power behind the described socket; The port that is provided with of described ATD is connected with potentiometer.
As a kind of preferred version, amplifying circuit described in the utility model adopts transistor amplifier.
As another kind of preferred version, ATD described in the utility model adopts the LM567 ATD.
The utility model beneficial effect
1, safer
The utility model casing is provided with socket, switch, microphone, indicator light and potentiometer knob, be provided with ATD in the described casing, the input of ATD links to each other with microphone by amplifying circuit, the output of ATD is leaded up to first resistance and is linked to each other with dc power anode, another road of the output of ATD links to each other with transistor base by second resistance, transistor collector links to each other with dc power anode, transistor emitter links to each other with relay control end one end by described switch, the relay control end other end links to each other with dc power cathode, and the controlled end of relay is connected and linked to each other with civil power behind the described socket; The port that is provided with of described ATD is connected with potentiometer; Blow a whistle insulating pot with water boiled after, can sound, sound inputs to ATD by microphone, amplifying circuit, ATD with input signal with frequency be set compare, when satisfying condition, send control signal relay is disconnected, the blow a whistle insulating pot and the civil power disconnection that will link to each other with socket.So the utility model is safer.
2, environmental protection, energy-conservation
Because the utility model can cut off the power supply the insulating pot of blowing a whistle immediately, do not have unnecessary steam volatilization and waste of electric energy after the insulating pot of blowing a whistle is boiled with water.So the utility model environmental protection, energy-conservation.
3, easy to use
Be convenient to according to the concrete insulating pot of blowing a whistle by the utility model potentiometer knob, ATD is finely tuned, be convenient to the electric control that adds by switch to socket, prevent that the utility model one from powering up, socket just links to each other with civil power, thereby the insulating pot of blowing a whistle that links to each other with socket is powered up, and produce the situation of dry combustion method.Whether in addition, be convenient to observe the utility model by indicator light is powered.
4, simple in structure
The utility model mainly comprises socket, switch, microphone, indicator light, potentiometer, ATD; Member is few, connects simply, so the utility model is simple in structure.
