Description

A kind of can auto-breaking and the adjustable supply socket of output voltage

. technical field

The utility model patent relates to a kind of supply socket, have people leave after can auto-breaking and the output voltage function that can regulate, inoperable high-power warming appliance use in suitable unmanned situation.

. background technology

Every winter, when being cold, a lot of people was accustomed to warming oneself by powerful space heater.Sometimes after people leaves, forget power-off, or after power failure, forget closedown socket power, after incoming call, warmer just works when unmanned again, if space heater works long hours in unmanned situation, often easily causes fire.Similar to not closing warmer power supply in unmanned situation or again to send a telegram here after having a power failure and the fire that causes all can occur a lot of every year, cause serious property loss and casualties.

. summary of the invention

In order to eliminate this potential safety hazard, a kind of smart jack of the utility model patented invention, possesses following functions: can auto-breaking through the delay time rear socket that arranges after people leaves; In loaded situation, the output voltage of socket is adjustable, thus the power of regulating load.

The technical scheme adopted is: when interrupteur SW is placed in automated location, pyroelectric infrared sensor D203S can convert the infrared ray that the human body sensed discharges to the faint signal of telecommunication and deliver to high performance transducing signal process integrated circuit BIS0001, amplify through internal secondary and signal is amplified, again via the two-way amplitude discriminator process in inside, export high level signal and make transistor V saturation conduction, drive power cut off delay time relay KT work, Bidirectional thyristor trigger circuit is connected after the power cut off delay normally opened contact of KT is closed, in the situation of socket access power consumption equipment, bidirectional thyristor just energy conducting, power consumption equipment normally works, indicator light L2 is luminous simultaneously, socket for indicating just in working order.If once people forgets after leaving disconnect socket switch SB, pyroelectric infrared sensor D203S can't detect human body signal, IC output signal is low level, transistor V ends, time relay KT dead electricity, its power cut off delay normally opened contact break trigger circuit after the delay time of setting, bidirectional thyristor ends, deenergization, thus realize automatically disconnecting socket power when unmanned.If people is of short duration leaving, return within the time of setting, the time relay again electricly make bidirectional thyristor maintenance conducting, make socket can not power-off.

R1, Rp, C1, VD1 constitute the Trigger Angle regulating circuit of bidirectional thyristor, and regulator potentiometer Rp just can the effective value of adjustable socket output voltage.

. embodiment

Socket has hand control and automation selector switch, and when SW is placed in manual position, socket does not possess automatic circuit break function, does not also have voltage-regulation function, is equivalent to general supply socket, and now L1 lamp is shinny.

When interrupteur SW is placed in automated location, possesses the function that output voltage is adjustable, people leaves rear auto-breaking.First Fresnel Lenses by receive human body radiation focus IR radiation after, add to interference filter element, light, sunlight and other infrared radiation, except allowing the infrared radiation of the wave-length coverage of human-body emitting and passing through, can also be kept outside of the door, prevent these interference signals from causing false triggering by filter plate.The infrared ray that filtered human body distributes adds to pyroelectric sensor D203S two and detects in unit, after detection unit can convert the infrared ray that the human body sensed discharges to the faint signal of telecommunication, deliver to high performance transducing signal process integrated circuit BIS0001, through the enlarge leadingly of inner amplifier, the second level of operational amplifier is amplified, DC potential is raised for delivering to the two-way amplitude discriminator be made up of two voltage comparator COP1 and COP2 after built-in voltage Um, detect effective triggering signal Us, when Us is less than built-in voltage (about 1V), two-way amplitude discriminator exports as low level, not output signal.Then export as high level when Us is greater than built-in voltage, if now there is the upper saltus step forward position of triggering signal Us to arrive, then can start-up study timer, after the time of time delay, output V0 is high level.Transistor V saturation conduction, drives the work of the power cut off delay time relay, after normally opened contact is closed, start capacitor charging, after electric capacity C1 both end voltage is greater than the trigger voltage of bidirectional trigger diode, bidirectional trigger diode conducting, connects Bidirectional thyristor trigger circuit.Now when socket access power consumption equipment, bidirectional thyristor conducting, power consumption equipment normally works, and now L1 and L2 lamp is simultaneously shinny.Regulate current potential Rp, making can charging interval of control capacittance C1, and the charging interval of electric capacity determines the speed of bidirectional trigger diode VD1 triggering and conducting, thus regulates the Trigger Angle of bidirectional thyristor, realize the adjustment of the output voltage of socket, the power of power consumption equipment is regulated.

After people leaves, cut-off push button SB to disconnect the power supply of socket.If forget and disconnect socket switch SB, pyroelectric infrared sensor D203S can't detect human body signal, the V0 pin output signal of BIS0001 is low level, transistor V ends, time relay dead electricity, its power cut off delay contact disconnects after the time of setting, thus break trigger circuit, bidirectional thyristor is ended, thus realizes automatically disconnecting socket power when unmanned.If people is of short duration leaving, return within the time of setting, after infrared sensor detects signal the time relay again electricly make bidirectional thyristor maintenance conducting, make socket can not power-off.

If after power-off, forget and disconnect socket switch SB, again after incoming call, under unmanned state, the V0 pin output signal of BIS0001 is similarly low level, and bidirectional thyristor ends, power consumption equipment can not work, thus under ensureing unmanned state, large power-consuming equipment can not run, and guarantees Electrical Safety.

Socket functions of indicator light illustrates: when L1 lamp is bright, and represent and get to manual gear, now socket has electricity, but output voltage is non-adjustable, without automatic circuit break function; When L2 lamp is bright, represent that automatic gear got to by socket, but socket does not access power consumption equipment, socket no-output voltage; When L1 and L2 lamp is simultaneously shinny, represent that automatic gear got to by socket, power consumption equipment works, and socket output voltage is adjustable.L3 is alarm lamp, and when L3 is bright, represent that automatic gear got to by socket, and now nobody uses socket, prompting user wants disconnecting power switch SB.
