Description
Technical field
The present invention is relevant for a kind of atomizer structure, be meant vibrations especially with vibrations element such as piezoelectric, make auxiliary vibrations element accept vibration energy and back and forth vibrations, and then make the liquid in the spray nozzle sheet fluctuating extruding fluid reservoir, make liquid discharge the atomizer structure that forms fog from spray orifice.
Background technology
Being seen on the market atomizer has two kinds of pressure type and mechanical concussion formulas.The former utilizes very big pressure differential with the atomization of liquid, though effect that can atomized amount, its shortcoming be particle big, need the bigger and cost of the machine, the noise that improve pressure than higher.The atomizer of machinery concussion formula is to utilize ultrasonic vibrations to come liquid is produced the cavitation corrosion phenomenon, and then allow cracked vacuole form droplet, produce the effect of atomizing, but this atomizing type has its shortcoming to exist, and for example: power consumption is big, need that fan provides that fog direction of transfer, volume are big, atomized drop is not of uniform size or the like.
In the atomizer based on piezoelectric, shown in Fig. 6 a～6b, except the mode of above-mentioned ultrasonic atomizing, the atomizer that the spray nozzle sheet 90 of arranging in pairs or groups in addition in addition uses, this spray nozzle sheet 90 has the jut 91 of cima shape, and jut 91 is provided with several spray orifices 92.Atomizer has added after the spray nozzle sheet 90, can reduce the electric energy of use greatly, and through the effect in aperture, makes granular size controlled.
Relevant at present patent or product roughly can be divided into two classes: the one, and utilize the piezoelectric vibrations that liquid is extruded spray nozzle sheet 90 and form fog, another is to utilize piezoelectric vibrations spray nozzle sheet 90, makes it to pat liquid, allows liquid discharge from spray orifice 92 and forms fog.The former needs bigger energy to go to drive the piezoelectric vibrations for producing short grained droplet, liquid could be extruded atomizing, with effect, a little less than the latter.
Yet the cost ratio of the element of this kind atomizer is the highest with the cost of spray nozzle sheet, accounts for about 30%.If can reduce the usable floor area of spray nozzle sheet, do not influence atomization quantity and atomizing effect simultaneously thus, then can promote its utilizability, cost of manufacture also can reduce a lot.In addition, at the spray nozzle sheet of electrotyping forming, because material is in the majority with nickel and copper, its resonant frequency can be lower, causes under some vibrations mode and can produce harsh noise.If be applied in the atomizer of medical purpose, then be not suitable for the patient and use, otherwise influence patient's mood easily, influence medical effect.
Shown in Fig. 6 a～6b, from machining angle, because the spray nozzle sheet of electrotyping forming 90 thickness are extremely thin, about about 30 μ m, remake projection processing, it is excessive and produce slight crack that the jut 91 of its cima shape is easy to stress, and part spray orifice 92 also can torsional deformation and influence the atomizing result.
Now that the relevant patent description of spray nozzle sheet is as follows:
US4605167 number: technical characterictic is that spray nozzle sheet is done convex design, the spray nozzle sheet area is relatively large; Its shortcoming is: 1. cost of manufacture is higher, comprises spray nozzle sheet moulding and projection processing.2. the spray nozzle sheet use amount is higher relatively.3. having noise when liquid is used up produces.
US5518179 number: technical characterictic is that spray nozzle sheet does not have convex design, the spray nozzle sheet area is relatively large; Its shortcoming is: 1. spray nozzle sheet use cost height.2. nebulization efficiency is limited.3. having noise when liquid is used up produces.
By the above as can be known, existing atomizer is unsatisfactory, and improved necessity is arranged.
