Description
Technical field
The utility model is related to a kind of power-supply circuit, it is electric that specifically a kind of list fire takes electric smart electronics switch on wall to take
Road.
Background technology
Switch on wall in the market develops in terms of electronization, intelligence, Networking, remote controlization.Currently on the market
Oneself through there is the intelligent electronic switch of the Networkings such as many WIFI, bluetooth, ZIGBEE control, but because WIFI, bluetooth,
The operating current of the electronic circuits such as ZIGBEE is larger（Its operating current is up to 40 milliamperes or so）, can only be inscribed into alternating current in switch
Zero firewire is used by electronic circuits such as the Switching Power Supply decompression supply WIFI of switch internal, bluetooth, ZIGBEE.For zero fire
The switch of power supply has a disadvantage that because to increase a zero curve in corresponding switch bottom case：One, entire room is more
Many lines are planted, this will increase wiring expense.Two, because increasing a zero curve, such switch bottom case in switch bottom case
In just have zero curve, and have firewire, if this both threads has been accidentally run into together, will short circuit, have equal danger on fire
Danger.Three, most basic reason is the tradition based on electrician, this is it is difficult to change.So in order to substitute old-fashioned mechanical switch,
It avoids rewiring, intelligent switch from requiring to be compatible with old-fashioned switch, can directly substitute old-fashioned switch.
But existing single firewire switch uses the way to take power with load in series, when loading OFF state, to ensure small work(
The problem of work and flicker will not occur because of electric leakage in the load of rate, so the electric energy that single firewire switch takes out from concatenated load
No more than 220 volts 100 microamperes, if this leakage current all provides electric current by the Switching Power Supply decompression of single firewire switch internal
Afterwards, maximum power supply electric energy is also no more than 5 volts 2 milliamperes（Low current switch power supply it is less efficient, do not exceed 50%）.Consider
After each section electric leakage of single firewire switch internal circuit, actual power electric current only understands smaller.So present single firewire switch
Quiescent current cannot be satisfied the consumption of WIFI, bluetooth, ZIGBEE etc..
Also occur the load lamps and lanterns of direct Networking control in the market（Or control module）, load end directly by mobile phone or
The inadequate problem of operating current is also not present because of load end continued power in remote control control.But pass through mobile phone or distant
Control device control load is far from the real-time and conveniently of local side control load, when such as using mobile phone operation load lamp state, user
It is required for digging out mobile phone every time, opens mobile phone, unlock mobile phone, into operation interface, then adjust the state of load lamp.In addition, washing
When bath or wash vegetables, when having water on hand, at this moment user just will not more lack the condition of service load lamp with mobile phone or remote controler
?.So local side wall operation panel is necessary and necessary.In addition for the load lamps and lanterns of direct Networking control, because
There are problems that electronic component failure, so it, which manipulates reliability, can not show a candle to mechanical switch, as WIFI, bluetooth, ZIGBEE etc.
After electronic circuit failure, user just loses the control ability and means to load lamp, therefore the wall operation panel of local side
Band on-off switch is also needed to, in the control damage of the electronic circuits such as WIFI, bluetooth, ZIGBEE, it is negative to provide another control
Carry the replenishment control mode of lamp switch.It, can be with deenergization, to change load lamp simultaneously when load lamp damages.

Fig. 1 is the circuit diagram of the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of list fire takes electric smart electronics switch on wall power-supply circuit, including on-off switch, power-supply circuit,
Current rectifying and wave filtering circuit, DC-DC power source and linear voltage decreasing power supply, the on-off switch connect power-supply circuit, and power-supply circuit is also connected with
Current rectifying and wave filtering circuit, current rectifying and wave filtering circuit are also connected with DC-DC power source, and DC-DC power source is also connected with linear voltage decreasing power supply.
On-off switch has multiple, and power-supply circuit is made of silicon-controlled and bi-directional voltage stabilizing pipe, and the connection of silicon-controlled T2 pins is more
A on-off switch, then it is connected to by on-off switch the terminal of load, power grid center line is reached by load, silicon-controlled T2 is except connection
Outside on-off switch, also G is connected to by two back-to-back voltage-stabiliser tubes and triggers pin, the phase line that LINE terminals get access to grid passes through
Internal circuit is connected to silicon-controlled T1 pins.
Current rectifying and wave filtering circuit includes bridge type rectifier and the filter capacitor that is connected in parallel therewith, as the utility model into
One step technical solution：The current rectifying and wave filtering circuit includes bridge type rectifier and the filter capacitor that is connected in parallel therewith, bridge type rectification
2 feet of device connect silicon-controlled T1 feet, and 3 feet of bridge type rectifier connect silicon-controlled T2 feet.
The operation principle of the utility model is：The phase line that LINE terminals get access to grid is connected to silicon-controlled by internal circuit
T1 pins, silicon-controlled T2 pins connect multiple on-off switches, then the terminal of load is connected to by on-off switch, by loading to
Up to power grid center line.Silicon-controlled T2 is also connected to G triggerings by two back-to-back voltage-stabiliser tubes and draws in addition to connecting on-off switch
Foot.When voltage in this way between silicon-controlled T1 and T2 pins is more than the clamp voltage of voltage-stabiliser tube, controlled silicon conducting is connected in this way
Rectification is gone out the operating current equal to voltage-stabiliser tube clamp voltage by the rectifier bridge of silicon-controlled T1 and T2 pins, after capacitor filtering,
It is used for subsequent Switching Power Supply.It is connected on the chopping depressuring scheme that the Switching Power Supply after rectifier bridge uses Width funtion, it will be higher
Voltage drops to 5V, then drops to 3.3V by LDO, is used for circuit below.
For by it is silicon-controlled with two back-to-back regulator tube groups at circuit, the voltage between silicon-controlled T1 and T2 is less than
Silicon-controlled to be not turned on when the clamp voltage of voltage-stabiliser tube, electric current can lead to the rectifier bridge being connected afterwards with T1 and T2, and after supply
Face circuit uses, this has been equivalent on silicon-controlled T1 and T2 in parallel and has loaded, if the bearing power after rectifier bridge is larger, etc.
The load resistance imitated in silicon-controlled upper parallel connection is smaller, and the electric current of bigger is thus needed to can be only achieved the clamp voltage of voltage-stabiliser tube,
Triggering controlled silicon conducting could be connected in the clamp circuit of voltage-stabiliser tube, silicon-controlled to maintain conducting always before alternating current again zero passage
State.Because connect on silicon-controlled triggering foot back-to-back two voltage-stabiliser tubes to clamp circuit, alternating current is just
Negative half period, clamp circuit can trigger controlled silicon conducting.For silicon-controlled, because its conduction voltage drop is also smaller, so work
Calorific value is also smaller.
