It makes an explanation below to the working principle of the ultra-low-volume sprayer of the utility model:

The ultra-low-volume sprayer of the utility model, blower 5 are driven using direct current generator, open power switch, direct current Machine work, blower 5 operate, and adjust drive speed adjustor 36, select suitable position as needed, so that direct current generator keeps suitable Revolving speed, in the case, blower 5 generate high-speed flow, and high-speed flow is concentrated in the cavity 4 of shell 1 and by its inner wall stream To two-way directive wheel 9, the circulation path of high-speed flow is divided into three: one a of path: blower 5, cavity 4, wind guide chamber clockwise 25, Spray holes 20 and centre bore 8；Two b of path: blower 5, cavity 4, air-guiding hole 22, wind guide chamber counterclockwise 26 and centre bore 8；Path three C: blower 5, cavity 4, muffler 11 and medicine-chest 2 are equipped with helicla flute 10 in 7 inner wall of mask out, and high-speed flow passes through helicla flute 10 When, certain screw type wind can be generated, more quickly, smooth.A part of high-speed flow flows into medicine-chest 2 simultaneously by muffler 11 Make to generate certain air pressure in medicine-chest 2, liquid connecting tube is circulated to out by medicine absorbing tube 12 by the medical fluid in the medicine-chest 2 to pressurize 13, by Flow-rate adjustment valve module 14,15 flow nozzle 16 of outlet tube, regulating flow quantity valve assembly 14 herein, to set Determine the instantaneous flow of medical fluid, medical fluid is sprayed from nozzle 16, and at the same time, high-speed flow flows to the suitable of two-way 9 rear end of directive wheel Hour hands wind guide chamber 25, gap 33 of the high speed eddy airstream generated through wind guide chamber 25 clockwise between nozzle 16 and spray holes 20 Into spray holes 20, so that carry out first time separation in spray holes 20 from the water droplet that nozzle 16 sprays and generate atomization, Then, the primary water mist by first time atomization separation is sprayed from spray holes, it may be assumed that primary water mist appears in several wind-guidings counterclockwise The center that chamber 26 is formed, in the moment of ejection, primary water mist is generated in the case where wind guide chamber 26 counterclockwise is into the traditional method of indicating the pronunciation of a Chinese character to effect It is equivalent to the air-flow of twice blower wind speed, so that atomization more slot river levee, mist particle diameter is smaller, passes through test, droplet Minimum diameter can reach 15 μm, so that medical fluid generation be made to diffuse state, medical fluid skyborne diffusion time extends, to increase The service efficiency of medical fluid, the size of droplet, which can pass through, adjusts drive speed adjustor 36, the combination synthesis of Flow-rate adjustment valve module 14 Depending on collocation, this product droplet mist particle diameter can reach 15-50 μm.

The utility model is different according to the environment used, can match the connection type operation for lengthening component 39, medical fluid warp Outlet tube 15, transition sebific duct 43, nozzle 16 path spray, high-speed flow through blower 5, cavity 4, spiral sebific duct 40, two-way lead It is flowed out to the path of wheel 9, centre bore 8.The application of component 39 is lengthened, so that user is when in use, more humanized, convenience is more By force.

Lengthening component 39 is mounted in the outlet 3 of shell 1 by attachment cap 41, refers here to two nozzles, one The first jet being connect with outlet tube 15, the other is the second nozzle being connect with 43 outer end of transition sebific duct, first jet with The inner end of transition sebific duct 43 connects, and the spray assembly for exporting 3 positions is removable unloads the front end for being mounted on handle 42 down, thus shape It is complete with the spraying machine for lengthening component at one.

Blower 5 is mounted in inside shell 1, and shell 1 is screwed on battery case 37, and battery case 37 passes through this Included be threadedly coupled of body is fixed on medicine-chest 2.

35 electricity of lithium battery is finished, and is charged normal are as follows: charger socket is inserted into charging socket 38, when needing to grow Time Continuous can latch 44 rotational shells 1 for lithium battery 35 from battery by opening with several groups of lithium batteries 35 of prepare more when working It is taken out in box 37 and changes the full lithium battery 35 of electricity and continue operation, while can will changed through lithium battery 35 itself institute The charging socket 38 of band individually charges, to will not influence work.

Ultra-low-volume sprayer provided by the utility model embodiment is described in detail above, it is used herein Specific case is expounded the principles of the present invention and embodiment, and the explanation of above example is only intended to help Understand the revealed technical solution of the utility model；At the same time, for those skilled in the art, according to the utility model Thought, there will be changes in the specific implementation manner and application range, in conclusion the content of the present specification should not be construed as The limitation of the utility model.
