Abstract

The utility model relates to a timing and quantitative automatic sprayer, comprising a door 1, a housing 2, a fixing plate 3, a control switch 11, and an agent bottle 12. The utility model is characterized in that the timing and quantitative automatic sprayer also comprises a motor 7, double gear 4, 5, a shaft gear 6, a fan gear 8, an electronic switch plate 9, a quantitative valve 10, and a battery 13, wherein, the electronic switch plate 9 can send out the timing pulse to control the start of the motor 7 and control the periodical quantitative spraying of the quantitative valve through the gear transmission. The utility model is used for the sterilization, the disinsection, and the air control. Besides, the utility model is suitable for the automatic spraying of the public space and the household.

Description

Timing and quantitative automatic sprayer

The utility model relates to antomobile sprayer, particularly the small-sized antomobile sprayer of electronic switch control spraying.The sprayer of prior art is seen the CN2031314U patent specification, its shortcoming is that used valve is a common valve, during each the spraying, press down just spray, ability stop-spraying up to not according to valve the time, control circuit is controlled the time of pressing valve in this way, but because there is randomness in the transmission mechanism action, thereby can not reach metered injection.

The purpose of this utility model is to provide a kind of rational in infrastructure, antomobile sprayer at regular time and quantity that volume is little.

Below in conjunction with description of drawings the utility model.

Fig. 1 is the structure chart of antomobile sprayer at regular time and quantity of the present utility model.

Fig. 2 is the elevating arc 8 shape figure among Fig. 1.

Fig. 3 is the circuit theory diagrams among Fig. 1.

See Fig. 1, at regular time and quantity antomobile sprayer of the present utility model comprises door 1, shell 2, fixed head 3, gauge tap 11, agent bottle 12, it is characterized by and also comprise motor 7, doubly-linked gear 4,5, shaft gear 6, elevating arc 8, electronic switch plate 9, quantitative valve 10, battery 13.

Be equipped with on the fixed head 3 motor 7, doubly-linked gear 4,5 and axle, electronic switch plate 9, gauge tap 11, agent bottle 12, the battery upper and lower of elevating arc 8 have spring leaf to withstand, spring leaf and as the extraction pole of battery supply.

Shaft gear 6 is installed on the motor 7, the large fluted disc interlock of shaft gear 6 and doubly-linked gear 4, the gear wheel interlock of the pinion of doubly-linked gear 4 and gear 5, the pinion of doubly-linked gear 5 and elevating arc 8 interlocks, the other end of elevating arc 8 is the lever (see figure 2), the quantitative valve 10 of lever end bottom alignment agent bottle 12, contacts just with 10.

Doubly-linked gear 4,5, shaft gear 6, elevating arc 8 are plastic gear, and in light weight, easy to process, cost is low.Motor 7 adopts the 3V special micromotor, battery 13 usefulness 1.5V1 batteries 2 joints.

The said gear transmission mechanism landing slow-speed of revolution and the effect that increases moment.

Referring to Fig. 3, be the circuit theory diagrams among Fig. 1, electronic switch plate 9 comprises: 555 timers, the PNP triode, resistance R 1, R2, R3, R4, capacitor C 1, C2, C3, K switch, 4 pin of 555 timers, 8 pin connect power supply "+" utmost point, 1 pin connects K switch, and 5 pin connect capacitor C 2, resistance R 1, capacitor C 1 series connection cross-over connection is between power supply "+" " " utmost point, R2 is connected to 7 pin and 6 pin, between 2 pin, R4 connects the base stage of 3 pin and Q, is the load of 555 timers, and R3 connects the base stage of power supply "+" utmost point and Q, be biasing resistor, C3 connects power supply "+", between "-" the utmost point, can improve the detent torque of motor 7, motor 7(is M) be connected between the colelctor electrode and " " of Q.555 timers and R1, R2, C1, C2 form pulse-generating circuit, and Q, R3, R4 form pulse amplifying circuit, spray one time mist when the connection of gauge tap K guarantees to place " ON " at switch, so that can be with hand switch control eruption when needing very fast eruption.

Embodiment:

Sprayer at regular time and quantity of the present utility model adopts 555 timers and positive-negative-positive triode Q to do the startup of pulse control motor 7, motor 7 adopts the 3V special micromotor, battery saves with No. 1 battery 2, resistance R 1 value 3.3M, R2 value 1.3K, R3 value 10K, R4 value 22 Ω, capacitor C 1 value 220 μ, C2 value 10 μ, C3 value 100 μ, K switch is a toggle switch, the high 200mm of machine, wide 120mm, thick 80mm.

The utility model operation principle is as follows: when gauge tap 11 is allocated to " ON ", electronic switch plate 9 is started working, the regularly pulse of sending the about 1S of width, this pulse control PNP pipe Q, PNP pipe Q conducting, motor 7 rotates, and the shaft gear 6 that drives on it rotates, and shaft gear 6 is stirred doubly-linked gear 4 and rotated, 4 drive doubly-linked gear 5 rotates, doubly-linked gear 5 is stirred sector gear 8 and is rotated, and the lever end of sector gear 8 presses down quantitative valve 10, sprays quantitative fog.After pulse was intact, motor stopped operating, the make progress lever end of cabin fan generating gear of the springs in the quantitative valve 10, and quantitative valve 10 resets, and sector gear resets, and waits for when pulse is sent next time spraying again.Place " OFF " position as gauge tap 11, quit work.

In sprayer at regular time and quantity of the present utility model, load onto the agent bottle that fills disinfectant or pesticide or air freshener, promptly can be jet at regular time and quantity, after agent bottle inner liquid medicine uses up, open door 1, take off former dose of bottle, recess with on the new agent bottle wiredrawn edge seam secured in alignment plate 3 gets final product by putting in place gently.
