The utility model has the advantages of good atomization effect and long jet distance.
Description
Technical field
The utility model relates to a kind of sprayer, especially a kind of low pressure vortex atomizing nozzle.
Background technology
Flit-gun at home and abroad is to be used for a kind of machinery of spray liquid on the market, is mainly used in aquas such as spraying various pesticides, perfume, deodorant, oil agent liquid.At present; Flit-gun on the market mainly is divided into several types: produce high pressure through the agent of can boosting and make liquid produce the manual flit-gun of atomizing, improve fluid pressure through manual thrust and produce the hand sprayer of atomizing and improve the power spraye that fluid pressure produces atomizing through electronic generation thrust.The expulsion pressure of the sprayer of can boosting agent is big; Jet length is long, scope reaches the even refinement of spraying granule greatly, and atomizing effect is better, but owing to have higher pressure all the time in the jar; Exist potential safety hazards such as blast, to transporting, store, carry and using and all bring many inconvenience.Therefore, being replaced by manual or electronic flit-gun is clear and definite development trend.With regard to present stage; Although occurred the different family expenses piston type intermittent hand sprayer of structure on the domestic and international market; Continue to use the nozzle arrangements of the sprayer of traditional can boosting agent but their common issue with is, and manual or electronic mode is difficult to the pressure that provides enough, causes atomizing effect bad; Jet length is not enough, influences insecticidal effect.
Summary of the invention
For the deficiency that atomizing effect is bad, jet length is short of the nozzle arrangements that overcomes existing sprayer, the utility model provides the low pressure vortex atomizing nozzle that a kind of atomizing effect is good, jet length is long.
The utility model solves the technical scheme that its technical problem adopted:
A kind of low pressure vortex atomizing nozzle; Comprise nozzle body and truncated cone-shaped conveyor screw; Said nozzle body is provided with internal taper hole, is provided with spray orifice in the end of nozzle body, and said internal taper hole is communicated with said spray orifice; The spirochetal outside of truncated cone-shaped is provided with at least two helicla flutes, and the truncated cone-shaped conveyor screw is nested in the internal taper hole of nozzle body slidably.
Further, the internal taper hole of the spirochetal front portion of said truncated cone-shaped is the taper spin chamber, and the interior cone angle of taper spin chamber is 65～90 °.
Further again, said helicla flute has three, and three helicla flutes are 120 ° of distributions; Certainly, also can be two helicla flutes, four conveyor screws or other; Usually the spiral fluted radius is constant.
Further, said helicla flute is for becoming the radius helicla flute, and is big at the radius in the radius ratio exit of helicla flute porch.
The beneficial effect of the utility model mainly shows: form spiral vortex atomizing nozzle structure, make liquid in the spin chamber, produce tangible eddy flow effect, can improve the atomizing effect of jet expansion.The swirling flow atomizing interaction energy makes under manual thrust or this situation that only can produce than low fluid pressure of electronic thrust, makes atomization of liquid better effects if, and jet length is farther.Simultaneously, whole nozzle arrangements is simple, convenient processing and manufacture, and volume is little, in light weight.
Description of drawings
Fig. 1 is the structural representation of low pressure vortex atomizing nozzle.
Fig. 2 is the spirochetal structural representation of truncated cone-shaped.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See figures.1.and.2; A kind of pressure vortex atomizing nozzle; Comprise nozzle body 1 and truncated cone-shaped conveyor screw 2, nozzle body 1 is provided with internal taper hole, and it is spray orifice 4 that the end of internal taper hole is provided with axially extending bore; Spray orifice 4 has certain outlet length, and the outside of truncated cone-shaped conveyor screw 2 is provided with 3 circular arc helicla flutes 6 that are the constant diameter of 120 degree distributions; As shown in Figure 2, truncated cone-shaped conveyor screw 2 sliding being contained in the internal taper hole of nozzle body 1, helicla flute 6 forms helical flow path with nozzle body 1 inwall, and voltage supply power liquid passes through.The spirochetal anterior taper spin chamber 5 that forms naturally of the internal taper hole of nozzle body 1 and truncated cone-shaped.The interior angle of taper of spin chamber is 65 to 90 °.
During work, liquid is under pressure through helical flow path, forms eddy flow liquid in the spin chamber by the screw action of runner, and eddy flow liquid sprays from nozzle, forms the liquid mist by atomizing.
The outside of described nozzle body 1 is provided with outer connecting thread 3, and is affixed through the siphunculus of outer connecting thread 3 nozzles and family expenses piston type intermittent hand sprayer.
The conveyor screw outer arc shape helicla flute 6 of present embodiment is for becoming radius, and promptly the circular arc helicla flute adopts big slightly inlet radius in the porch, and slightly little go out port radius, middle submissive transition are adopted in the exit.All the other structures of atomizer are with embodiment 1.Adopt change radius helicla flute 6 can change the eddy flow effect.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; Should not being regarded as of the protection domain of the utility model only limits to the concrete form that embodiment states, the protection domain of the utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
