Detailed description of the invention
Fig. 1 is the structural representation of prior art embodiment.Show in figure, in prior art, atomizer is formed by assembling parts such as nozzle connection 1, rear end cover 2, intermediate sleeve 3, nut 4, front end sleeve 5, nozzles 6, nozzle 6 inside has the striker 6.2 contained in spray chamber 6.1, spray chamber 6.1, in nozzle 6 front end, there is squit hole 6.1,6.2, schematic indication's two squit holes in figure, squit hole quantity has several and distributes in the form of a ring.Rear end cover 2 on be provided with the first gas circuit entrance A11.1, the second gas circuit entrance A11.2, schematic indication's two gas circuit entrances in figure, gas circuit entry number there are several and by water centered by distribute in the form of a ring.Show in figure, nozzle connection 1 is fixed on rear end cover 2.Nozzle connection 1 inside arranges water route B, and percolate by water entrance B11 enters undergauge channel B 21, flows through waterway channel B22, flows into front end sleeve 5 successively again.Gases at high pressure enter from gas circuit entrance A11.1, A11.2, flow through gap that intermediate sleeve 3 and nozzle connection 1 form after, converge at front end sleeve 5 place and percolate, gases at high pressure play jet atomization effect to percolate, the percolate of first atomization enters spray chamber 6.1 through the hole that flows through of front end sleeve, and sputtering atomization is again there is at striker 6.2 place, finally outwards accelerate to spray spray film from squit hole 6.31,6.32.
As can be seen from Figure 1, in prior art, atomizer is formed by six assembling parts such as nozzle connection 1, rear end cover 2, intermediate sleeve 3, nut 4, front end sleeve 5, nozzles 6, therefore in use there is following problem:
1. structure is comparatively complicated, and dismounting and change comparatively not easily.
2., when gas pressure is excessive, percolate ejection can be stopped and generation backflow even stops in spray chamber.And when percolate pressure is excessive, then percolate can be made to return and be retracted into gas passage, cause atomized drop particle to increase simultaneously, affect atomizing effect.
3. first compressed air and percolate mix in spray chamber, and passage is not independent.Percolate leaves dead angle when flowing out at the place such as spray chamber, front end sleeve, can not produce rapidly evaporation and effects of reduced temperature, has percolate to remain and causes accumulation, corrosion (percolate is for acid), and then blocking squit hole.
Fig. 2 is the structural representation of one embodiment of the invention.Show in figure, unlike the prior art, the present invention proposes the atomizer that a kind of percolate returns spray system, the integral structure that shower nozzle is made up of inwall 7.1, outer wall 7.2, mainly comprise air-channel system A and water circuit system B, air-channel system A comprises compressed air inlet, compressed air channel and compressed air outlet, and water circuit system B comprises the outlet of percolate entrance, percolate passage and percolate.
Show in figure, in this example, air-channel system A is made up of ring-shaped distributed point of gas circuit centered by several by water system B, and each point of gas circuit forms jet atomization region at respective outlet side, show in figure, air-channel system A comprises compressed air inlet A11, taper undergauge passage A21, the first gas channels A22.1, the second gas channels A22.2, the first gas circuit outlet A12.1, the second gas circuit outlet A12.2.Wherein, the first gas channels A22.1, the second gas channels A22.2 distribute centered by B for independent point gas circuit and by water in the form of a ring.
Water circuit system B is from entrance B11 to exporting B12 successively through undergauge channel B 21 and waterway channel B22.Wherein, B12 place is exported in amplifying expansion structure suddenly.Percolate flows into from entrance B11, is accelerated in undergauge channel B 21, sharply expands thus forms liquid droplets after flowing through waterway channel B22 at outlet B12 place.
Compressed air flows into from gas circuit entrance A11, accelerated at taper undergauge passage A21, after flowing through the first gas channels A22.1, the second gas channels A22.2, form low-voltage high speed air flow stream at outlet A12.1, A12.2 place, converge with liquid droplets, carry out secondary injection atomization.Show in figure, compared with prior art, the atomizer that the present invention proposes has the following advantages:
1. due to gas passage and percolate passage separate, the change of gas pressure can not cause the phenomenon of backflowing of percolate.The optimization of atomizing effect just can be realized by adjusting compressed-air actuated pressure, simple.
2. percolate passage is isometrical passage, without dead angle.Can be that last jet band is from cleaning effect when spraying next time.
3. shower nozzle is integral type structure, and structure is very simple, and dismounting and change is easy, effectively improves maintenance efficiency.And percolate can bring for shower nozzle the effect that cools preferably through producing evaporation under turbulent condition.
4. can realize the complete compatibility with original spray-head interface.
