Abstract

The utility model belongs to the field of switches and particularly relates to a touch control switch. The touch control switch comprises a switch panel, and a control circuit board connected with an electric appliance. The control circuit board is provided with a relay. A back surface of the switch panel is provided with a vibration sensing piece used for converting a vibration signal into a voltage signal. The control circuit board is provided with a control unit connected with the relay and a voltage amplifier used for receiving and amplifying the voltage signal of the vibration sensing piece. The control circuit board sends the voltage signal of the voltage amplifier to the control unit. The control unit controls the on-off of the relay to control the on-off of a circuit further. The touch control switch utilizes the vibration sensing piece to obtain signals, so that danger that a traditional switch generates open fire is prevented, and disadvantages that a current employed capacitive sensing touch switch is inaccurate and unstable are overcome. According to the touch control switch, electromagnetic interference is prevented, waterproof and dustproof arrangement is not required, and an effect of long-term stability is achieved.

Description

A kind of touch control switch
Technical field
The utility model belongs to field of switches, is specially a kind of touch control switch.
Background technology
Soft-touch control is a kind of switch on wall of Based Intelligent Control, generally refers to a kind of switch on wall of application touch sensible chip principle design, is the regeneration product of traditional mechanical push-key type switch on wall.Can realize soft-touch control more intelligent, more convenient operation has the incomparable advantage of traditional switch, is popular a kind of decorative switch of current family product.
The touch control switch of use generally all adopts the mode of capacitive sensing or resistance induction to realize crawl signal at present.But soft-touch control itself need to consume certain electric energy, in the time of standby, because single fiery intelligent switch standby power taking is electric current by flowing through electric ballast to the power supply of Intelligent wall switch control circuit, if the little stand-by circuit that will cause of standby input current can not be worked, if having cold flash of light incandescent lamp after will causing greatly electronic ballast lamp to close, standby input current closes the problems such as rear red silk.In when work, during due to single fiery intelligent switch work, power taking is that two ends pressure reduction while disconnecting by switch carrys out power taking, has not just had the pressure reduction cannot power taking in the time of switch closure, dead electricity problem out of control will cause like this control circuit to be opened time.Therefore the technical barrier of single live wire soft-touch control power taking exists always, and the research and development difficulty of micro-power consumption list live wire standby and working power circuit is very large, and up to the present this is still the main technical bottleneck of domestic and international restriction list live wire soft-touch control development.
Realize real capacitor induction type soft-touch control, need stable single live wire power supply to process and reliable and stable touch sensible chip, accomplish anti-error triggering, anti-various electromagnetic interference, load disturbance, environmental interference, even need the Intelligent touch switch functional requirements such as functions of waterproof and dustproof, the system scheme of integrated induction touch function is the technical barrier in industry especially.
Especially, the technology of touch sensitive panel main flow is to adopt capacitive sensing technology to realize.Because the capacitance variations that finger brings in inductive disks is minimum, and along with the insulating panel thickness of isolation increases, the size of electric capacity can reduce by exponentially.General after the toughened glass of 5mm, people's finger touch can only bring the capacitance variations less than 0.5PF.For small like this measurement, the variation of humidity, temperature, electromagnetic interference, power supply interference etc. all can affect the measurement result of measuring circuit greatly.If there is no the long-time stability under the very difficult especially various adverse circumstances of working stability that guarantee touch sensitive panel of special, professional treating method.
Summary of the invention
For overcoming the above problems, the utility model provides the touch control switch that a kind of stability is strong.
A kind of touch control switch, comprise switch panel, and the control circuit board being connected with electrical equipment, control circuit board is provided with relay, the described switch panel back side is provided with the vibration induction sheet that vibration signal is converted into voltage signal, described control circuit board is provided with the control unit being connected with relay and the voltage amplifier that the voltage signal of vibration induction sheet is received and amplified, the voltage signal of voltage amplifier is passed to control unit by control circuit board, the switch of control unit control relay, and then control circuit switch.
Further, described vibration induction sheet is fixed on the back side of switch panel by high-strength double-face glue.
Further, on described switch panel, the position of corresponding sensing chip is pasted or is printed with and opens or closes mark.
Further, described switch panel is metal or plastic material.
The utility model is realized and is captured signal by a kind of vibration induction sheet, both can avoid the danger of traditional switch generation naked light, can avoid again inaccurate, the unsettled shortcoming of the capacitor induction type soft-touch control using at present.The touch control switch that the utility model provides can in case various electromagnetic interference, do not need to carry out water proof and dust proof setting, reach effect steady in a long-term.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model switch panel schematic diagram.
Embodiment
Switch panel of the present utility model, vibration induction sheet, voltage amplifier and relay are market and buy.
Described control circuit board and the control unit of control relay thereof, can be by the single-chip microcomputer of buying on market, the corresponding program of record of reburning.
As shown in Figure 1-2, a kind of touch control switch, comprise switch panel 1, and the control circuit board 3 being connected with electrical equipment, control circuit board is provided with relay 4, described switch panel 1 is metal material (also can be plastic material), the front of the position of switch panel 1 corresponding sensing chip be printed with open or close mark 5(also can be directly stick on above), switch panel 1 back side is provided with the vibration induction sheet 2 that vibration signal is converted into voltage signal, and vibration induction sheet 2 is fixed on the back side of switch panel 1 by high-strength double-face glue.Described control circuit board 3 is provided with the voltage signal of vibration induction sheet 2 is received and the voltage amplifier that amplifies and the control unit of control relay.Control circuit board 3 passes to the voltage signal of voltage amplifier on the switch of control unit control relay 4, and then control circuit switch.
When use, when staff touch on switch panel 1 open or close mark 5 time, metal (or plastics) material switch panel 1 corresponding finger contact area can produce very slight vibration, the vibration that this is trickle can be detected and produce voltage signal and switch panel 1 opens or closes the vibration induction sheet 2 at mark 5 back side, then by control circuit board 3, the signal of voltage amplifier is passed to the control unit that is arranged on control circuit board 3, the break-make that control unit carries out control relay realizes the control to electrical equipment.
