Preferably, described MCU module adopts PIC single chip microcomputer as control core, and described button comprises switching on and shutting down button, function button, arranges button and LED light.
Preferably, described power module comprises USB and powers and powered battery.
Preferably, ultrasonic wave perfume atomization circuit of the present utility model can also comprise: the low-voltage testing circuit connecting MCU module and battery module respectively, for detecting cell voltage and outputs level signals extremely described single-chip microcomputer.
In order to more clear the technical solution of the utility model, set forth some application examples of the present utility model further below in conjunction with accompanying drawing.
For MCU module, PIC16F913 single-chip microcomputer can be adopted as control core, also comprise LED light, instruction relevant work state; Button arranges switching on and shutting down button, function button, arranges button, arranges LED light etc.
Wherein, PIC16F913 single-chip microcomputer is 8 COMS single-chip microcomputers, interior band lcd driver and EPPROM data storing, and single-chip microcomputer operating current reaches nA level under energy-conservation park mode, and product stand-by time when using powered battery can be made greatly to increase.
For clock module, clock chip DS1302 can be adopted.
For power module, external USB Power supply can be adopted to be main, powered battery is that auxiliary mode is powered.Without battery-powered during external power source, when there being external USB plant-grid connection, powered battery is cut off, and turns and to be powered by USB and not charge to battery.
Above-mentioned functions can utilize the switching function of metal-oxide-semiconductor to realize, shown in figure 3, Fig. 3 is the circuit theory diagrams of the power module of an example, when accessing without external power source, P raceway groove M1 grounded-grid makes its conducting, thus make M3 grid become high voltage, M3 conducting, battery (BT) by M3 to load supplying.When there being USB power source to access, M1 cut-off, M2 conducting thus make M3 grounded-grid, M3 is in cut-off state at this moment, and battery does not discharge, and USB power source just by diode D2 to load supplying.As shown in Figure 2.
For low-voltage testing circuit, generally, in single-chip microcomputer, the voltage of battery can be detected by the AD conversion moment, but consider that single-chip microcomputer internal resource is limited, therefore, devise low-voltage testing circuit to realize this function at this.
Shown in figure 4, Fig. 4 is the circuit theory diagrams of the low-voltage testing circuit of an example, this circuit can utilize the switching characteristic of triode Q to realize, cell voltage is by R4, R5 resistance-type dividing potential drop, positive pole and divider resistance R4, the R5 of connecting between negative pole of voltage, the negative pole that the base stage of triode connects between two divider resistances R4, R5 by resistance R6, colelctor electrode connects positive source, emitter stage connection power supply by resistance R7.The triode ON when cell voltage is greater than 3.7V, output low level is held by L_CHECK, when voltage is less than 3.7V, triode ends, high level is exported by L_CHECK end, single-chip microcomputer just can simply by identifying that the level that L_CHECK end exports distinguishes whether battery is in low-pressure state, reduces taking mcu resource.
For display module, consider and need to show nebulisation time, institute thinks that reducing costs the undersized short in size LCD of employing shows.The advantage of this LCD is that volume is little, low in energy consumption, and PIC16F913 single-chip microcomputer carries the driver of this LCD, so preferably consider to select GDC0209 display screen.
For atomization circuit, shown in figure 5, Fig. 5 is the circuit theory diagrams of the atomization circuit of an example, producing frequency by LC vibration is the wave of oscillation of 110KHz, then by power tube Q4 and transformer, ultrasonic wave is boosted to 40V, and high frequency oscillation ripple stimulates atomizing piece by build-out resistor again, convert electrical energy into mechanical energy, thus make atomizing piece produce dither, the water touching atomizing piece internal layer is dispersed as the fine globule, reaches atomizing.
The utility model also provides a kind of perfume atomiser, comprises above-mentioned ultrasonic wave perfume atomization circuit and perfume bogey; Wherein, described ultrasonic wave perfume atomization circuit exports high frequency oscillation ripple to atomizing piece, and the perfume in perfume bogey is dispersed as the fine globule.
As an example, can shown in reference diagram 6, Fig. 6 is the working-flow of the utility model perfume atomiser example, main realization powers on, system initialization, key scan, read data and displaying time, spraying starts, and low pressure detects, report to the police, arrange (set of time, the available machine time is arranged, and the unused time is arranged, spray time is arranged), the functions such as shutdown.
The perfume atomiser of comprehensive above-described embodiment, take full advantage of the performance advantage of single-chip microcomputer at control field, machine switching on and shutting down time, nebulisation time, atomization interval time can be set freely, there is the function such as battery electric quantity detection and power down preservation data simultaneously, be applicable to the occasion that family, office space etc. use perfume.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
