Abstract

The utility model provides a take audible cue's switch, including electric switch, the live wire, load and zero line contact, electric switch's both ends are connected respectively with electrical apparatus load and live wire, live wire and zero line contact connect gradually voltage reducing module with four -hole network circuit structure, rectifier module, the linkage independent switch, trigger module and pronunciation warning chip, the voice output termination of reminding the chip at pronunciation has the speaker, pronunciation remind the power of chip and ground to hold the output of connecting rectifier module respectively high, the cold end, linkage independent switch and electric independence of electric switch and linkage action. The utility model has the advantages of being simple in structure and convenient in operation, job stabilization is effective, through the on off state of the speaker warning light that can be vocal of switching on, can be arranged in solving the problem that the blind person lived, and resources are saved has just improved the security.

Description

A kind of switch with auditory tone cues

Technical field

The utility model belongs to living electric apparatus technical field, is specifically related to a kind of switch with auditory tone cues.

Background technology

Known, in life, blind person is a special colony, because cannot see light, so usually do not know the state that the state of electric light or appliance switch is opened or closed, particularly, if the installation of switch is lack of standardization when finishing is installed, on off state is obscured, and is difficult to judge whether switch closes by the location status of switch.

Utility model content

For overcoming the defect existing for prior art, the utility model provides a kind of switch with auditory tone cues, cannot see whether electrical equipment connects electricity, the problem of uncontrollable switch to solve blind person.

The switch of described band auditory tone cues, comprise appliance switch, live wire, load and zero line contact, the two ends of described appliance switch connect electrical appliance load and live wire respectively, it is characterized in that: described live wire is connected voltage reduction module with zero line contact successively with four mouthfuls of lattice network structures, rectification module, interlock independent switch, trigger module and voice reminder chip, loud speaker is connected at the sound output of described voice reminder chip, the output that the VDD-to-VSS end of described voice reminder chip connects described rectification module is respectively high, cold end, the electrically independent and linkage action of described interlock independent switch and described appliance switch.

Especially, the input of described trigger module is provided with differential circuit, the output of differential circuit connects the control end of bidirectional triode thyristor SCR, the negative electrode of described bidirectional triode thyristor SCR connects the cold end of described rectification module, anode connects the hot end of rectification module by resistance R, and the anode of described bidirectional triode thyristor SCR is connected as the trigger end of described trigger module output with described voice reminder chip.

Further, filter capacitor C are accessed with four mouthfuls of lattice network structures between described rectification module and described interlock independent switch.

The beneficial effect that the utility model has is: structure is simple, easy to operate, and working stability is effective.

In the technical program, the feature of differential circuit is that the saltus step of forward is converted into a positive pulse, the saltus step of negative sense is converted into a negative pulse, and bidirectional triode thyristor can be undertaken triggering and conducting by positive pulse or negative pulse, just in time the open and closed of switch are that the power supply of corresponding electrical appliance is led to and broken and realizes in turn, and corresponding Music Clip is also the sound playing two kinds of audio frequency in turn.And differential circuit just in time only exports a pulse, makes Music Clip only play an audio sound, loud speaker can be broken and put down.

Can the on off state of loud speaker warning light of sounding by energising, may be used for solving the problem in blindman, economize on resources and improve fail safe.

Embodiment

A kind of switch with auditory tone cues described as shown in Figure 1, Figure 2, the switch of described band auditory tone cues, comprise appliance switch 1, live wire, load and zero line contact, the two ends of described appliance switch 1 connect electrical appliance load and live wire respectively, and described live wire is connected voltage reduction module 2, rectification module 3, filter capacitor C, interlock independent switch 4, trigger module 5 and voice reminder chip 6 with zero line contact successively with four mouthfuls of lattice network structures.

As shown in Figure 2, loud speaker 7 is connected at the sound output of described voice reminder chip 6, the VDD-to-VSS end of described voice reminder chip 6 connects the high and low potential end of output of described rectification module respectively, the electrically independent and linkage action of described interlock independent switch 4 and described appliance switch 1.

A kind of embodiment is, the input of described trigger module 5 is provided with differential circuit, the output of differential circuit connects the control end of bidirectional triode thyristor SCR, the negative electrode of described bidirectional triode thyristor SCR connects the cold end of described rectification module, anode connects the hot end of rectification module by resistance R, and the anode of described bidirectional triode thyristor SCR is connected with the trigger end of described voice reminder chip as described trigger module 5 output.The voice that speech chip can arrange two states are play in turn, respectively the corresponding on off state switched on and off.

The feature of differential circuit is that the saltus step of forward is converted into a positive pulse, the saltus step of negative sense is converted into a negative pulse, and bidirectional triode thyristor can be undertaken triggering and conducting by positive pulse or negative pulse, just in time the open and closed of switch are that the power supply of corresponding electrical appliance is led to and broken and realizes in turn, and corresponding Music Clip is also the sound playing two kinds of audio frequency in turn.And differential circuit just in time only exports a pulse, makes Music Clip only play an audio sound, loud speaker can be broken and put down.

During use, when the switch is opened, differential circuit exports forward waveform in the moment of switch change and triggers controlled silicon conducting, output current potential step-down triggering voice chip exports voice signal, control loudspeaker is play the audio frequency set and is connected voice, and when the switch is closed, differential circuit exports negative sense waveform in the moment of switch change and triggers controlled silicon conducting, output current potential step-down triggering voice chip exports voice signal, and the disconnection voice set play by control loudspeaker.

Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although be described in detail the utility model with reference to above-described embodiment, will be understood by those skilled in the art that: still can modify to the utility model or equivalent replacement, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of right of the present utility model.
