The specific embodiment
By the start research to piezoelectric type atomizer core component-piezoelectric ceramics ultrasound atomizer plate (as shown in Figure 1), we find that atomizing piece metallic membrane in motion process exists the phenomenon of flexural deformation inequality.On metallic membrane, to exist central area internal strain amount large in orifice distributed areas, and orifice edges of regions is partly out of shape less, and deflection is by the outside ever-reduced feature in center, and concrete deformation as shown in Figure 2,3.
Known according to the diastrophic relevant knowledge of plate shell in Elasticity, when metallic membrane is done bending motion, on metallic membrane thickness direction, exist a neutral line O-O(physically not exist), neutral line top is inconsistent (arrow represents to be subject to force direction) with the stressing conditions of below.When metallic membrane is bent downwardly, neutral line upper end material 001 pressurized, lower end material 002 tension, action effect is as shown in Figure 4; Otherwise, when metallic membrane is bent upwards, neutral line upper end material 001 tension, lower end material 002 pressurized, action effect is as shown in Figure 5.
The diastrophic inconsistent and upper and lower side material (001 and 002) of metallic membrane is subject to the inconsistent of force direction, directly the duty of orifice in metallic membrane has been impacted and final decision atomizing effect.For better explanation, we set forth in conjunction with Fig. 6,7,8,9.As shown in Figure 6, tapered, the taper hole miner diameter end diameter of orifice structure is
, taper hole bigger diameter end diameter is
.Neutral line is O-O, and the orifice cavity volume of neutral line top is
, below volume is
.When metallic membrane is bent downwardly, neutral line upper end material 001 pressurized, lower end material 002 tension, orifice miner diameter end diameter becomes because pressure-acting dwindles
, bigger diameter end diameter Yin Lali effect expands and becomes
, neutral line top cavity volume becomes
, below cavity volume becomes
, as shown in Figure 9; Otherwise, when metallic membrane is bent upwards, neutral line upper end material 001 tension, lower end material 002 pressurized, the effect of orifice miner diameter end diameter tension power expands and becomes
, bigger diameter end diameter is reduced into because of pressure-acting
, neutral line top cavity volume becomes
, below cavity volume becomes
, as shown in Figure 8.For from orifice path one side atomization (cone angle
meet
) atomizing piece, by integral and calculating, have
,
,
.By
known, when atomizing piece is bent downwardly motion, the volume of orifice
volume while being bent upwards with respect to atomizing piece
increase, so be bent downwardly direction when motion by being bent upwards to transfer to when metallic membrane, orifice volume increases, and orifice sucks liquid from outside, is to inhale journey; When metallic membrane is bent upwards direction when motion by being bent downwardly to transfer to, orifice volume reduces, and in orifice, liquid is discharged from, and at the first opening of atomizing piece, has droplet to produce, and is scheduling.To sum up analyze knownly, the atomizing particle size of final atomization is the aperture in the scheduling stage by the first opening
determine.For the atomizing piece that adopts arc generatrix taper orifice (Fig. 7), its action effect is also the same with principle, at this, repeats no more.
Known by above-mentioned analysis, atomizing piece (Fig. 1) aperture that present stage is used is on all four, so be out of shape inside and outside metallic membrane under the inconsistent condition of severe degree, in orifice region, the orifice of ectonexine is at first hatch bore diameter in scheduling stage
be inconsistent (shown in Figure 10 ~ 12), and then cause atomizing particle not of uniform size, atomizing effect is not good.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail: the present embodiment be under the first type piezoelectric ceramic atomizer patch that the utility model proposes (only include a slice the first metallic membrane and a slice the first piezoelectric ceramics ring plate forms) structure orifice that implement and that adopt be bellmouth.Provided detailed case study below and implemented and analyzed, but it must be noted that protection domain of the present utility model is not limited to the present embodiment.
Figure 13 and Figure 14 have provided each area distribution schematic diagram and cutaway view of the present utility model in the present embodiment.As Figure 13, shown in 14, in the utility model structure, mainly include: the first metallic membrane 1, the first piezoelectric ceramics ring plate 2.On the first metallic membrane 1, there is the first intensive orifice region 3, outwards there is the orifice of Different structural parameters in the first intensive orifice region 3 by center, be numbered respectively orifice 11, orifice 22, orifice 33, the orifice adopting is taper, all orifices are all provided with the first opening 5 and the second opening 6, the area that the first piezoelectric ceramics ring plate 2 is provided with the first intensive orifice region 3 on the first through hole 4, the first metallic membranes 1 is less than or equal to the area that the first through hole 4 covers.The first metallic membrane 1 and the first piezoelectric ceramics ring plate 2 are bonded together by binding agent.
Under alternating current effect, the first piezoelectric ceramics ring plate 2 is because inverse piezoelectric effect effect is by the vibration producing radially, and then does upwards or reclinate motion with the first metallic membrane 1, and movement effects can be with reference to Fig. 2 and Fig. 3.From figure, we can find out, the first metallic membrane 1 bending deformation quantity is outwards constantly reduced by center, and mid portion flexural deformation is the most violent.
In the atomizing piece the utility model proposes, the first opening 5 diameters of internal layer orifice 11 are
, the first opening 5 diameters of intermediate layer orifice 22 are
, the first opening diameter of outer orifice 33 is
, and meet
.Because the severe degree because of the distortion in the first intensive orifice region 3 in work scheduling is outwards constantly to reduce by center, so
expansion the most acutely becomes
,
take second place, expand and be
,
expand minimum becoming
, final realization has
, even from the atomizing particle size of the first opening 5 ejections like this, atomizing effect is even more ideal.
