Description
The utility model relates to a kind of touch switch on wall, and particularly a kind of little power consumption inductive switch is used for the light fixture of family and public place, the switch control of electrical equipment.
Touch switch on wall of the prior art is to adopt controllable silicon to drive loaded work piece as driving element, controllable silicon damages when driving such as inductive loads such as Inductive ballast formula fluorescent lamp, electricity-saving lamp, ventilating fans easily, and can not use fluorescent lamp and electricity-saving lamp.Because the desired heat dissipation problem of controllable silicon is restricted its bringing onto load power.In addition, the silicon controlled conduction voltage drop is bigger, and especially the conduction voltage drop of two lines system electronic formula switch is bigger, and the switch conduction pressure drop that has is restricted its application up to 20V.And the electronic switch that adopts the common electrical magnetic relay needs add at coil when the adhesive of contact and keeps electric current, and power consumption is bigger.
The purpose of this utility model is to provide a kind of little power consumption soft-touch control, adopt magnetic latching relay as driving element, only the need drive circuit can make switch open to the logical pulse current of relay coil or cut out, relay coil is only at the switch open or the instantaneous consumed power of closing, consumed power not at ordinary times, can realize little power consumption of inductive switch, power saving more.Because adopting the open and close mode of relay contact to make the switch conduction pressure drop is zero, can be with high power load, and workload-adaptability is strong, can be with various loads such as fluorescent lamp, electricity-saving lamp, incandescent lamp and ventilating fan.
The technical solution of the utility model is: a kind of little power consumption soft-touch control is characterized in that: a circuit board assemblies and a rechargeable battery pack are installed in switch case, and rechargeable battery pack is connected with circuit board assemblies; Circuit board assemblies comprises magnetic latching relay, drive circuit, power circuit and has the touch control circuit of microcontroller chip, the coil of magnetic latching relay is connected with drive circuit, and the touch control circuit output port is connected with drive circuit and control Driver Circuit drives magnetic latching relay unlatching or off switch; Power circuit is connected with rechargeable battery pack, touch control circuit and drive circuit and provides electric power to it.
The utility model compared with prior art has the following advantages:
Only the need drive circuit can make switch open for the logical pulse current of coil of magnetic latching relay or cuts out, relay coil is only at the switch open or the instantaneous consumed power of closing, consumed power not at ordinary times, can realize not having zero line the two-wire system switch single channel and multichannel control and the single channel of three-wire system switch of zero line and little power consumption work of multichannel soft-touch control, power saving are more arranged.Because adopting the open and close mode of magnetic latching relay contact to make the switch conduction pressure drop is zero, power consumption was both low, can be with high power load again, and workload-adaptability is strong, can be with various loads such as fluorescent lamp, electricity-saving lamp, incandescent lamp and ventilating fan.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a resistance-capacitance depressurization type circuit theory schematic diagram of the present utility model;
Fig. 2 is a transformer voltage-dropping type circuit theory schematic diagram of the present utility model;
Fig. 3 is battery voltage detection of the present utility model, power failure test section circuit theory schematic diagram.
Referring to Fig. 1, A touch control circuit, B are drive circuit, and C is a power circuit, and BT is a rechargeable battery pack, and RL is a magnetic latching relay.There is a microcontroller chip touch control circuit A inside, the switch surface is equipped with touch electrode and is connected to the input port of microcontroller chip, send control commands corresponding after handling by microcontroller when the touch signal of staff is input to microcontroller, this part is a prior art, in this few description.
The contact of magnetic latching relay RL is in parallel with the binding post L and the LOAD of switch, input with power circuit C is connected then, and the capacitor C 1 that the input of power circuit C has passed through the step-down effect is connected with the input of resistance R 7 with the rectifier bridge of diode D3～D6 composition.The dc output end of rectifier bridge is connected with voltage stabilizing didoe D7 and diode D8 through resistance R 8, and voltage stabilizing didoe D7 can be stabilized in voltage in the rated range, to prevent over-charging of battery.The negative pole of diode D8 is connected with the positive pole of rechargeable battery pack BT.Diode D8 can prevent that battery discharges by voltage stabilizing didoe behind mains failure.
The dc output end VDD of power circuit C is connected with the power input of touch control circuit A and the power input VDD among the drive circuit B respectively, the driving port of touch control circuit A respectively with drive circuit B in resistance R 1 be connected with R2.In drive circuit B, when pulse signal of resistance R 1 input, triode T1, T3, T6 conducting, T2, T4, T5 end, and the coil of magnetic latching relay RL leads to direct impulse voltage, and the closing of contact of RL is opened load.When pulse signal of resistance R 2 inputs, triode T2, T4, T5 conducting, T1, T3, T6 end, and magnetic latching relay RL coil leads to reverse impulse voltage, and the contact of RL disconnects, and load is closed.Since only need at switch open and the instantaneous magnetic latching relay coil electricity of giving of closing, not power consumption at ordinary times, and power consumption is very low, can make switch make little power consumption type.
Referring to Fig. 2, replaced by transformer TR by the resistance-capacitance depressurization element in the power circuit with the difference of circuit shown in Figure 1.
When descending power circuit in off position, switch can through electric capacity and resistance step-down, offer inductive control circuit, drive circuit and magnetic latching relay behind the diode rectification directly from switch terminal LOAD and L input civil power.When the closing of contact of switch magnetic latching relay RL after unlatching, make the voltage of switch input terminal reduce to zero, can provide electric power to control circuit, drive circuit and magnetic latching relay this moment by battery.
