Abstract
The utility model discloses an acoustic-optic device of a vending machine. An acoustic-optic transducer is connected to a control circuit for controlling turning on, turning off and holding time of a sound-producing device or a light-emitting device, and the control circuit is connected with an acoustic-optic device. The acoustic-optic device of a vending machine has the advantages of simple structure and convenient manufacture, enhances a promotion function and the competitive ability of a vending machine, and is favorable for popularization and application of the vending machine.
Description
The utility model is about automatic vending machine, and more particularly, the utility model is the acousto-optic device of using about automatic vending machine.
At present, the automatic vending machine kind of selling on market is a lot, does not see the automatic vending machine that sounding, light-emitting device are housed as yet.
The purpose of this utility model provides a kind of automatic vending machine acousto-optic device simple in structure, easy to use, and it helps sales promotion, the promotion and application of automatic vending machine.
The technical solution of the utility model is summarized as follows.
The acousto-optic sensor connection control circuit is in order to the time that opens and closes and keep of control sound-producing device or light-emitting device, described control circuit sending and receiving acoustic device.
Described acousto-optic sensor can adopt infrared ray sensor, ultrasonic sensor etc.Described sound-producing device can adopt sound circuit or cassette player etc.But described control circuit is the sending and receiving electro-optical device also.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is circuit theory diagrams of the present utility model.
In the drawings, the output terminating diode D1 negative pole of acousto-optic sensor G, diode D1 positive pole is succeeded electrical equipment J coil and sustained diode 2, connects negative supply after the parallel connection.Relay J-1 is a normally opened contact, one termination positive supply, and another termination time relay sj coil, and connect negative supply after in parallel with sustained diode 3, and the termination cathode power supply of the make delay break contact SJ-1 of the described time relay, the other end divides two-way; The trigger end that meets sound circuit Y behind the switch XK-1 is selected in one tunnel selecting; Another road connects sending and receiving optical diode D4 positive pole behind the current-limiting resistance R, minus earth.The power supply of cassette player is controlled by selector switch XK-2 and time relay make delay break contact SJ-2.
Acousto-optic sensor can adopt infrared ray sensor, certainly, also can adopt ultrasonic sensor, human body pyroelectric sensor etc.Described sensor can be surveyed the dead ahead with one; Also can adopt a plurality ofly, survey a plurality of directions.During near automatic vending machine, when promptly entering the surveyed area of sensor, sensor just sends signal as the people, and Drive and Control Circuit starts sound-producing device and light-emitting device.Described sound-producing device can adopt sound circuit or cassette player etc.Described light-emitting device can adopt light emitting diode, neon lamp, bulb etc.Be provided with electronic time relay in control circuit, when client leaves automatic vending machine during a period of time, relay just cuts out acousto-optic device.
After acousto-optic sensor G receives the close signal of people, output terminal credit becoming noble potential.Through diode D1 output, make the relay J coil electricity, relay normally open contact J-1 connects, the time relay sj coil electricity, its contact SJ-1 is that normal opened contact is opened in the moment make delay, so it connects the trigger end of sound circuit Y immediately, also connects luminous display circuit D4 simultaneously.If when needing to use cassette player, selector switch XK-1 can be disconnected, XK-2 connects, and～220V power supply is connected cassette player through XK-2 and time relay sj-2 contact.The cassette player key often is in open state, and cassette player should have automatic upset band function.When the people left, acousto-optic sensor G output terminal recovered electronegative potential, relay J coil blackout, its contact J-1 disconnects, the disconnection of delaying time of time relay sj coil blackout, SJ-1, SJ-2 works on a period of time sound circuit or cassette player and luminous display circuit.
The beneficial effects of the utility model are:
1. simple in structure, easy to make.
2. promotional function and the competitiveness of automatic vending machine have been strengthened.
3. be conducive to applying of automatic vending machine.
Claims (5)
1. the acousto-optic device that automatic vending machine is used is characterized in that, the acousto-optic sensor connection control circuit is in order to the time that opens and closes and keep of control sound-producing device or light-emitting device, described control circuit sending and receiving acoustic device.
2. the acousto-optic device that automatic vending machine according to claim 1 is used is characterized in that, described acousto-optic sensor is infrared ray sensor or ultrasonic sensor.
3. the acousto-optic device that automatic vending machine according to claim 1 is used is characterized in that, described sound-producing device is a sound circuit.
4. the acousto-optic device that automatic vending machine according to claim 1 is used is characterized in that, described sound-producing device is a cassette player.
5. the acousto-optic device that automatic vending machine according to claim 1 is used is characterized in that, described control circuit sending and receiving electro-optical device.
