Use procedure of the present utility model: the course of work describing the welcome of this USB port charging here from two kinds of situations:
When guest greeting device accumulator 4 electricity abundance time:
The first step, USB charging inlet 1 to be placed in USB charging inlet telescopic chute 2, guest greeting device housing 10 is placed in doorway, shop;
Second step, open guest greeting device switch 6, guest greeting device is started working;
3rd step, when having people through sensor devices, the health for people can obstruct the light, and the light intensity that photoresistance RG1 receives changes signal; Intensity variation signal is coupled through C2, after the plus and blowup that Q1 etc. forms, and the inverting input of input IC1; The signal that this signal and in-phase input end input is inner after operation amplifier process at IC1, the audio generating circuit work of drive IC 1 inside, and " you are good, welcome sight to face in generation! " sound signal, through loudspeaker SP1 complete electroacoustic conversion, make people's ear can hear this greeting.
If the 4th step thinks that guest greeting device sound is too little or too large, inappropriate words, only need the volume adjuster 9 regulating guest greeting device gently;
5th step, place guest greeting device, adjust volume, after guest greeting device normally works, as long as have people to arrive greeting that doorway, shop guest greeting device will send " you are good, and welcome ", make the cordiality that the client into shop feels very.The whole course of work completes;
When guest greeting device accumulator needs charging time:
The first step, when accumulator 4 electricity of guest greeting device is very low time, there are two ways, one is if guest greeting device does not temporarily use, that just takes off guest greeting device, be placed into electric equipment with USB charge port as notebook computer charges, to be charged complete after the step repeating the first situation again will be used to use guest greeting device.Two outer ways use charger baby exactly, describe in detail below concrete steps;
Second step, first the switch 6 of guest greeting device cuts out, then charger baby is placed on the place that guest greeting device is placed, by the USB charging inlet 1 of guest greeting device, from USB charging inlet telescopic chute 2, fech connection is to the USB interface of charger baby, and charging indicator light is bright;
3rd step, complete second step after, opened by guest greeting device switch 6, guest greeting device is started working.
4th step, guest greeting device repeat the first situation step after normally working can use, here no longer repeated description.
5th step, after guest greeting device charge in batteries completes, USB charging inlet 1 to be pulled out from charger baby, and USB charging inlet 1 is placed in USB charging inlet telescopic chute 2, complete charging use procedure.
The beneficial effects of the utility model are: this guest greeting device passes through USB charging inlet to charge in batteries, can avoid regularly replacing battery, accumulator can repeatedly charge and use, energy-saving and environmental protection, structure is simple, convenient and practical, can reduce use cost, decreasing pollution, improves the stability of guest greeting device sounding.
