Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

A kind of syrup mixer disclosed in the present embodiment, including it is arranged at the observation of the upper surface of syrup mixer body 1 Window 2 and it is arranged at the inner side of syrup mixer body 1 and the not illuminating lamp 3 in the range of observation of observation window 2, in addition to be arranged at The outside of syrup mixer body 1 with detect the bright situation of external environment and export light detection signal bright detection means 11st, it is preset with benchmark value signal and is coupled to bright detection means 11 to receive light detection signal and by benchmark value signal and light Bright detection signal is compared and the voltage comparator device 13 of output voltage comparison signal, is coupled to voltage comparator device 13 to connect Receive voltage comparison signal and in response to voltage comparison signal to open and close the control device 12 of illuminating lamp 3；When the light detection letter Number be more than benchmark value signal when, illuminating lamp 3 light.

Here it is the dust on effectively reduction observation window 2, is hinged with cover plate 9 on the side wall of observation window 2, the quantity of cover plate 9 is Two pieces and it is symmetrical set, when cover plate 9 covers observation window 2 described in two, the observation window 2 is completely covered, and in cover plate 9 On be provided with handle 10.

When need not use observation window 2, now two cover plates 9 are covered, and are being needed in observation syrup mixer When portion's working condition, now only need to catch handle 10 to open cover plate 9.

Here bright detection means 11 includes the resistance R1 of one end ground connection, one end and is connected to resistance R1 and other end connection In power supply VCC photo resistance RG, the model 5537 of photo resistance RG here.

Syrup mixer also includes being arranged between bright detection means 11 and voltage comparator device 13 amplifying light inspection Survey the voltage amplification device 4 of signal.

Voltage amplification device 4 includes resistance R2, the positive that one end is connected to resistance R1 and photo resistance RG tie point Input be connected to the voltage amplifier A1 of resistance R2 one end, one end practice be connected to voltage amplifier A1 inverting input and The resistance R3 of other end ground connection, one end are connected to voltage amplifier A1 inverting input and resistance R3 tie point and another End is connected to the resistance R4, voltage amplifier A1 model AD620 of voltage amplifier A1 output end.

Voltage comparator device 13 includes being used for the reference circuit 5 of output reference value signal and is coupled to bright detection means 11 is more electric to receive the voltage ratio of light detection signal and benchmark value signal and output voltage comparison signal to control device 12 Road 6.

Reference circuit 5 including one end be connected to the slide rheostat RP1 of power supply, one end be connected to slide rheostat RP1 and The resistance R5 of other end ground connection, voltage comparator device 13 is connected to resistance R5's and slide rheostat RP1 including normal phase input end The voltage comparator A2 of tie point, voltage comparator A2 model LM393.

The control device 12 includes being coupled to voltage comparator device 13 with receiving voltage comparison signal and exporting people's physical examination Survey the human testing circuit 7 of signal, be coupled to human body detection device to receive human testing signal and in response to human testing believe Number to open and close the control circuit 8 of illuminating lamp 3.

Here human testing circuit 7 is the pyroelectric sensor that one end is connected to power supply, and control circuit 8 connects for base stage Be connected to the triode Q1 of pyroelectric sensor in voltage comparator A2 output end and colelctor electrode, triode Q1 be NPN type and Model S9014.

The specific work process of foregoing circuit is as follows：

Detected by the bright situation of photo resistance RG environment to external world, it is corresponding photosensitive with the reduction of light Resistance RG resistance will also increase, and the voltage being now carried on resistance R1 will be reduced, and examine light by voltage amplifier A1 After survey signal is amplified, now light detection signal will be transmitted on voltage comparator A2.

Here the corresponding voltage being carried on resistance R5 can be changed by changing slide rheostat RP1 resistance, passed through Voltage comparator A2 can realize the comparison of light detection signal and benchmark value signal.

When light detection signal is more than benchmark value signal, show that inconvenient user of service sees now extraneous light Examine the situation inside syrup mixer, now triode Q1 will triggering and conducting, by that can be carried out by pyroelectric sensor Human testing causes the power supply of illuminating lamp 3 to waste to avoid the illuminating lamp 3 under unmanned observation from lighting.

When and if only if bright dark and nigh someone, now illuminating lamp 3 will light irradiation syrup mixer Inside in order to the observation of user of service.

This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but As long as all being protected in right of the present utility model by Patent Law.
