Below in conjunction with above-mentioned accompanying drawing embodiment of the present utility model is remake and to describe in further detail.

Automatically the housing of odorator (referring to Fig. 1-6) is made up of chassis (1), front shroud (7) and top cover (6), all adopts injection molding, and front shroud adopts the hook groove to be connected with the chassis, utilizes the elasticity of plastics itself to snap in hook even, and top cover and chassis adopt screw to fix.

Be provided with fragrant jar (5) with fragrant mouth (4) in the chamber of housing, it is bearing on two semi arch supports with the chassis integrated through injection molding, and fragrant jar is the outsourcing product, comes from Nanjing angel Industrial Co., Ltd. and produces, and is the vapour-pressure type basin.Fragrant jar fragrant power is three grades of decelerations from the reduction gearing mechanism that battery DC power supply, motor M drive, this mechanism is located between motor and the fragrant mouth, and be located at and the fixed dividing plate in chassis (1) (10) on, outward by top cover (6) sealing, comprise being connected the gear Z that rotates synchronously with the motor axle key ₁, with gear Z ₁The duplicate gear Z of engagement ₂, with the duplicate gear Z of gear Z2 engagement ₃, with gear Z ₃The escapement (3) of engagement, escapement is the sector structure, and extends a fore-set, does regularly to rotate the fragrant mouth action of bump mouth over against compressible fragrant mouth, make the fragrance ejection in fragrant jar, the metered injection rear motor fragrant mouth that cuts off the power supply is closed by himself automatically replying function.When closing up the pushing tow escapement it is resetted, when escapement resets,, make it recover initial operating position because each gear meshing transmission makes motor reversing, prepare to work next time.

The fragrant control circuit of timing on the circuit board (2) is made up of clock frequency divider and hex inverter, and the outfan control motor of hex inverter rotates.The core parts of described timing frequency divider are that model is the ic chip of 74HC4060 ₁, also comprise peripheral cell: capacitor C ₁, C ₂, C ₃, resistance R ₁, R ₂, R ₃, R ₄, R ₁₁, light emitting diode DEL, audion Q ₁, K switch ₃Make time set, as 5 minutes the spray once or 10 minutes the spray once or 20 minutes the spray once, resistance R ₄Be variable resistance, regulate time constant, control open-interval length.Described hex inverter is that model is the ic chip of 74HC14P ₂, also comprise peripheral cell: capacitor C ₄, resistance R ₅, R ₆, R ₇, R ₈, R ₉, R ₁₀, resistance R ₆, R ₇Ground connection is accepted the photoconductive resistance RG of usefulness as light, audion Q2, and K switch 1 is an on and off switch, and K2 is the Working mode set switch, still is the setting that daytime, spray still all will be sprayed in 24 hours as the spray at night, and the user can select as required.IC ₁1. foot, 2. foot, 3. foot and IC ₂9. foot connect, by K switch ₃Control.IC ₁ foot and IC ₂5. foot, 6. foot connects, by K switch ₂Control.

Circuit working principle: turn on the power switch K ₁, the display lamp diode DEL in the display lamp window (9) is bright, be the work indication, and certain hour is once glittering at interval in the course of the work.This moment capacitor C ₂Produce pulse, make ic chip ₁The return-to-zero of foot, the beginning of clocking, IC ₁9. foot, 10. foot, foot are formed RC time constant adjusting circuit, IC ₁Another part circuit be 14 grades of frequency dividers, 1. foot, 2. foot, 3. foot is respectively the 12nd grade, the 13rd grade, the 14th grade, changes K ₃Can change terminal output and set and clock, be respectively 5 minutes, 10 minutes, 20 minutes, that is to say: as set 5 minutes, per 5 minutes circuit turn-ons once, as 10 minutes, conducting in then per 10 minutes once, these are by clock switch K ₃ Manually control.IC ₁4. foot is the 6th grade of frequency division output, trigger triode Q ₁Push And Release.

The Working mode set part is accepted window (8) by light and is made photoconductive resistance RG enter ic chip ₂(IC ₂Close for executing with hex inverter) the 1st, the 2nd inverter group sets all night, if then form the setting on daytime with the 3rd phase inverter, other has R ₇In the time of over the ground, form setting in 24 hours, that is to say when the mode of operation K switch ₂Manually be arranged on daytime during state, this odorator works by day, and do not work night, when being set in night, works at night, and do not work daytime, when being set in 24 hours, then all works at daytime, 24 hours nights.

IC ₁Frequency division is exported to C ₄Enter IC ₂9. foot the 4th phase inverter is by IC ₂8. foot output triggers Q ₂Push And Release (opening time is about 0.5 second, and open-interval length can be according to concrete working condition by variable resistance R ₄Time constant is regulated), make motor M energising or outage, control motor rotation (being about 0.5 second the duration of runs).

Power transmission process is by motor M driven gear Z ₁Do to rotate synchronously, thereby transmit driven gear Z through gears engaged ₂With gear Z ₃, drive escapement at last and rotate, form three grades of deceleration transmission, the rotation of escapement starts fragrant mouth action, realizes regularly fragrant purpose.
