Description
Technical field
The invention belongs to electric blanket fields, are related to a kind of electric blanket circuit.
Background technique
Electric blanket is one of product of commonly warming oneself in winter, and heat production speed is fast, high-efficient, cheap, becomes winter
Good sleep partner in house.Electric blanket mainly pass through heating wire heat production, if electric blanket forget after shutdown and it is long when
Between be powered, there will be security risk, be easy to cause fire, cause personnel and property loss, this case is not within minority.So
It is necessary to design a kind of highly-safe electric blanket, allow one to safe to use.
Summary of the invention
Electric blanket electricity consumption simple, easy to use that in order to compensate for the shortcomings of the prior art, the present invention provides a kind of structures
Road.
The present invention is achieved through the following technical solutions:
Electric blanket circuit of the invention, it is characterised in that: attaching plug is through fuse and temperature control insurance connection power switch, electricity
The switch terminal of source switch is once resistance R1, diode VD1, light emitting diode Q1 connection switch terminal two；Switch terminal one is also
One end of resistance R3 and resistance R4 through diode VD3 connection parallel connection, resistance R3 connect control unit with the other end of resistance R4
S, control unit S external temperature sensor and pressure sensor, terminal two also connect resistance R3 and resistance R4 after diode VD2
One end；Switch terminal connects resistance R2 after heating wire loads R, and heating wire loads R also through the connecting pin bidirectional triode thyristor BT
Son two, resistance R2 are sequentially connected adjustable resistance RW1, RW2, the one end capacitor C4, and capacitor C4 other end connection terminal two is two-way controllable
Silicon BT is through the one end diode ZL connection capacitor C4.
The invention has the advantages that realizing the auto-switch function of electric blanket, the use peace of electric blanket is improved
Quan Xing.Structure is simple, and design is rationally, easy to accomplish.Meet smart home idea of development, is provided to intelligentized life direction
It guides.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Attached drawing is a kind of specific embodiment of the invention.
Electric blanket circuit of the invention, attaching plug is through fuse and temperature control insurance connection power switch, power switch
Switch terminal once resistance R1, diode VD1, light emitting diode Q1 connection switch terminal two；Switch terminal one is also through two poles
One end of the resistance R3 and resistance R4 of pipe VD3 connection parallel connection, resistance R3 connect control unit S with the other end of resistance R4, control
Cell S external temperature sensor and pressure sensor, terminal two also connect the one of resistance R3 and resistance R4 after diode VD2
End；Switch terminal connects resistance R2 after heating wire loads R, and heating wire loads R also through bidirectional triode thyristor BT connection terminal two,
Resistance R2 is sequentially connected adjustable resistance RW1, RW2, the one end capacitor C4, capacitor C4 other end connection terminal two, bidirectional triode thyristor BT
Through the one end diode ZL connection capacitor C4.
Control unit S includes single-chip microcontroller, and single-chip microcontroller is separately connected temperature sensor and pressure sensor, in which: pressure passes
Sensor is set in electric blanket, and temperature sensor is used for senses room temperature, and pressure sensor and temperature sensor are all connected with single-chip microcontroller.
Temperature sensor incudes room temperature in real time, single when pressure sensor senses human pressure, room temperature lower than setting value
Piece machine controls electric blanket power-on switch and opens energization, electric blanket heat production.When pressure sensor influence electricity signal or room temperature
When higher than setting value, single-chip microcontroller control disconnects power-on switch, automatically powers off electric blanket.
