Description

Cross gas circuit atomizer

The utility model relates to a kind of atomizer, gas circuit atomizer particularly in parallel.

Existing atomizer is to utilize forced draft when nozzle sprays at a high speed, forms negative pressure principle near nozzle, and liquid rises to nearly nozzle place through pipette under the effect of pressure reduction, and air-flow is with its atomizing ejection.The atomizer that " the 36th piece of Pneumatic Transmission of mechanical engineering manual " provides adopts above-mentioned principle and nozzle, pipette structure with oil atomization.So-called secondary-atomizing is in atomizer mist of oil to be sprayed after the refinement once more.Atomizer also Chang Zuowei humidification device is used in lung ventilator." HFV series high frequency jet ventilator specification (Nanchang radio ten factories) ", the atomizer that is used for lung ventilator has been described, except that adopting said structure, also address another kind of version, promptly with minim pipette with fluid drips in nozzle the place ahead, air-flow is sent dropping liquid forth atomizing." B.E.SMITH The penlon bromsgrove high frequency jet ventilation for adults and paediatric use.A solution to the problems of humadificat-ion.Anaesthsia.1985.volume 40.P739-794 " reported a kind of atomizer in 1985, it is on the basis of said nozzle, pipette structure, add a spherical earthen table in the nozzle dead ahead, fog is injected on the spherical earthen table, and droplet clashes into the back fragmentation and further refinement ejection.Atomizer also is widely used in fields such as engines.

Existing atomizer generally has only one to spray gas circuit, and nozzle and atomising device fuse, and only can form fog before nozzle, fog can not be drawn and send larger distance.

The purpose of this utility model is that a kind of gas circuit atomizer in parallel will be provided, and when feeding forced draft, can make liquid form the even fog of mist droplet, particularly fog can be transported to more remote.

This gas circuit atomizer in parallel is made up of atomising device, gas circuit in parallel, outer nozzle, fluid infusion device, electric heater and reservoir.

Further feature of the present utility model is to have gas circuit in parallel, outer nozzle, fluid infusion device and electric heater.

Forced draft is divided into two-way after air intake duct input, a kind ofly spray at a high speed from the inner nozzle mouth, and the liquid in the reservoir rises to spout through pipette under differential pressure action, forms small droplet with the air-flow of ejection, forms the mist cloud in the reservoir chamber.The mist cloud is directed to the outer nozzle outer tube from defeated fog channel through fog conveying tube.Control valve on the defeated fog channel can be controlled the mist cloud amount of output.Another road forced draft is managed in appendix is directed to outer nozzle from gas off-take.When air-flow was managed ejection in outer nozzle, the mist cloud refinement once more with outer tube sprayed uniform fog from the outer nozzle spout.

Gas circuit in parallel is made up of defeated fog channel, control valve, fog conveying tube, gas off-take, appendix, and its terminal links to each other with outer nozzle.Control valve has the butterfly spool.Rotational valve core, defeated fog channel latus rectum changes, thus the mist cloud amount of control output.

Outer nozzle is made of concentric inner and outer pipe, and the even reducing of outer tube front end forms spray orifice, guarantees certain spray characteristic.

The fluid infusion device is made of taper hole, flap valve and gland.Taper hole can insert the liquid supplementation pipe joint on atomising device.When atomizer fed pressed gas, its inner chamber air pressure was greater than ambient pressure, and pressure reduction holds up flap valve and closes taper hole.When needing fluid infusion, overcome pressure reduction, flap valve is fallen, add liquid and can enter the atomizer inner chamber as long as add liquid.

Electric heater is made of contact pin, resistance wire and temp-controlling element.Contact pin is contained on the input adapter.In fog conveying tube and the appendix resistance wire is housed, resistance wire one end and contact pin link, and the temp-controlling element on the other end and the out splice going splice links.Temp-controlling element is contained on the inwall of out splice going splice, and its temperature-sensitive face is respectively in the tube chamber of fog conveying tube and appendix.When contact pin is introduced external power supply, the resistance wire heating, temperature raises in the pipe, temperature when setting value, the temp-controlling element disconnecting circuit.When temperature descended, temp-controlling element reclosed, thereby makes temperature remain on setting range.Select for use the temp-controlling element of different qualities can set different temperature values.

The utility model advantage and good effect compared with prior art is: fog is even, droplet is trickle; Fog can be transported to place far away through fog conveying tube, appendix, can reach 1.5 meters farthest; But defeated mist amount step-less adjustment; The fog temperature can remain on setting value; The power consumption of atomizer own is little, and can be in when work liquid make-up.Use this gas circuit atomizer in parallel to obtain evenly trickle fog at a distance, enlarged the scope of application of atomizer, improved practicality at the distance atomising device.
