Because atomizer and rotary clip removably connect, so can pull down atomizer, change the syndeton between atomizer and rotary clip, to change different work shower nozzles.For the convenient more good berth shower nozzle of the atomize different, the syndeton between syndeton, the hard bend pipe in embodiment 3 and skirt section, rotary clip between the pneumatic hose two ends in syndeton (Quick-mounting joint), embodiment 2 between skirt section and rotary clip in embodiment 1 and skirt section, rotary clip is all identical.
Series excited machine produces enough air quantity and blast, and through the air channel of front end case, blast is brought up to a sufficiently high level, obtains the steady air flow of high speed and high pressure.This high velocity air divides two-way ejection through atomizer, makes nozzle front produce certain negative pressure, cause liquid by siphon to nozzle place, thereby form higher relative velocity between two-way air-flow and liquid, realize twice atomization.Atomizer adopts strength atomizing principles, and adopts two stage cyclone atomization structure, can produce the droplet of aerosol rank and atomizing rank.
Atomizer and auto take-up are individual components, can carry out integral installation or integral demounting, are convenient to maintenance and maintenance.Utilize the Quick-mounting joint being equipped with, according to different spraying operation requirements, the spraying elbow of horizontal spraying joint, pneumatic hose as described in Example 2 and certain angle as described in Example 3 is as described in Example 1 installed.Utilize Quick-mounting joint to load onto pneumatic hose, Flow-rate adjustment knob is adjusted to high flow capacity, now produces the droplet of atomizing rank, can realize surperficial residual spray (spraying).When spray in needs space, can select to install the spraying elbow of horizontal spraying joint or certain angle, all need Flow-rate adjustment knob to be adjusted to low discharge, now will produce the droplet of aerosol rank, this rank droplet can be realized and fill the air infiltration control.Space is sprayed and is generally carried out timing sprinkling.During choosing dress horizontal spraying joint, do not need rotating spraying, and need rotating spraying, rapid Cover dissipation space during the spraying elbow of choosing dress certain angle.Timing spraying function relies on timing means to realize, and can select suitable timing according to epidemic prevention space size.Rotating spraying utilizes rotary control switch to open electric rotating machine and realizes.
Strength atomization system has three kinds of duties, horizontal positioned (referring to Fig. 1), erects and places (referring to Fig. 5) and the side back of the body, and horizontal positioned and erectting is placed by complete machine bottom with right-hand member arranges fulcrum 104, fulcrum 105 is realized, and side is carried on the back and relied on braces realization.When horizontal spraying joint is installed, is chosen as horizontal positioned or erects and place two kinds of duties; When the spraying elbow of certain angle is installed, recommendation is erect and is placed; When installing during pneumatic hose, use the mode of the braces side back of the body to aim at the controlling object operation of preventing epidemic.
Concrete use procedure: (1), according to different epidemic prevention environment and epidemic prevention requirement, select different spraying joints.In open environment or while there is specific epidemic prevention object, elect the residual spray of larger droplet as.Now, utilize rapid-assembling/disassembling joint that pneumatic hose is connected on atomizer; If the sealing in epidemic prevention region is higher, complex structure, elects the space spray modes of less droplet as.Space hour, optional dress horizontal spraying joint, when space is larger, the spraying elbow of optional dress certain angle.(2), by complete machine erect place, open medicine chest cover, in medicine-chest, add injecting medical liquid.Carry out after safety and routine inspection, then attaching plug is extracted out and is inserted in supply socket from auto take-up.(3) if elect residual spray as, Flow-rate adjustment knob is adjusted to high flow capacity, utilizes braces side back of the body epidemic prevention machine.Opening power gauge tap is to normally open, the generation atomizing of starting working, and hand-held pneumatic hose, aims at epidemic prevention object spraying operation.(4) while the space spray modes of horizontal spraying joint being installed if elect as, Flow-rate adjustment knob is adjusted to low discharge, complete machine is erect and is placed.Timing means is adjusted to suitable timing, turns on the power switch and be adjusted to time delay open position, operating personnel speed away.Under this pattern, possess Automatic Time Lag Function, after a period of time, the generation aerosol of starting working, realizes the space spraying operation that automatically fills the air infiltration.(5) if while electing the space spray modes of the spraying elbow that certain angle is installed as, and the space that horizontal spraying joint is installed sprays difference and is, needs rotating spraying operation.After needing power control switch to open, fast rotary control switch is opened, realized revolution space and spray.(6), during the end of job, powered-down gauge tap, utilizes auto take-up automatically power line to be regained.
By series excited machine, provide enough air quantity and blast, adopt the strength atomizing type of two-stage centrifugal impeller.When guaranteeing atomization quality, guarantee that equipment is reliable; By the micromachine in motor case, through crucial connection switching members such as swivel joint, rotation liquid collecting bar, rotary clips, drive shower nozzle rotation implementation space to spray, whole system compact conformation.
This technology is a kind of light, compact conformation, easy to maintenance, perfect in shape and function, possess that spray in space, the strength atomization system of two kinds of work patterns of residual spray, also realized the function that delayed start-up and timing are sprayed, the flow spraying is adjustable, mist droplet particle size is adjustable, the direction of spraying can be manually and automatic rotation, complete machine is can level sleeping to be put, uprightly place, portable, the side back of the body, is a kind of strength atomization system of multi-function operation.
