Description

The nozzle piece of sprayer unit and manufacture method thereof
Technical field
The present invention relates to a kind of atomization of liquid technology, particularly relate to a kind of nozzle piece and manufacture method thereof of sprayer unit.
Background technology
It is more and more extensive to utilize at present atomization system to carry out the application of technology of the atomization of liquid, be applied to the nozzle piece of sprayer unit from biomedical drug delivery system, provide the needed fuel oil of engine combustion to spray atomization system, and even the heat radiation cooling system that reaches by liquid phase-change etc. need the fully field of atomizing, all use atomizing principles, its relevant patent for example comprises that United States Patent (USP) announces the 4th, 465, No. 234, United States Patent (USP) announces the 4th, 605, No. 167, United States Patent (USP) announces the 6th, 089, No. 698, United States Patent (USP) announces the 6th, 235, No. 177, United States Patent (USP) announces the 6th, 629, No. 646, No. the 407529th, TaiWan, China patent announcement, No. the 449486th, TaiWan, China patent announcement, No. the 503129th, TaiWan, China patent announcement, No. the 506855th, TaiWan, China patent announcement, No. the 562704th, TaiWan, China patent announcement, and the technology such as TaiWan, China letters patent book number I222899 number.
See also shown in Fig. 8 A and Fig. 8 B, the existing nozzle piece that is applied to sprayer unit utilizes piezo-activator as the nozzle piece 20 of vibrator and a plurality of spray orifices 201 of the tool of arranging in pairs or groups more, make these nozzle piece 20 liquid 21 direct and to be atomized contact, by executing vibrate this liquid to be atomized 21 and spray via those spray orifices 201 and to break away from this body 20 of alive piezo-activator, produce thus atomizing effect.Yet, because existing nozzle piece is designed to symmetrical geometry more, liquid 201 in the device is to break away from (shown in Fig. 8 B) with the direction perpendicular to this body surface, make its spraying area be subject to spray orifice position of opening and the perforate scope of nozzle piece, and then make range of atomized flow too narrow, so that affect atomizing effect.Moreover, because range of atomized flow is too narrow, so that atomized drop (Droplet) clashes into accumulation each other, not only increase the size of atomized drop, more make atomizing effect not good, if will change range of atomized flow, then must relatively change the spray orifice distribution or adjust driving frequency, so certainly will increase system bulk, and carrying out needing higher resonance mode when large tracts of land drives, also consume the energy.
United States Patent (USP) announces the 4th, 465, then disclosing a kind of geometry by the change nozzle piece for No. 234 increases the semicircle nozzle piece that is applied to sprayer unit of atomizing area, and this nozzle piece that is applied to sprayer unit comprises having recess for the nozzle piece of receiving fluids, the nozzle of being located at this nozzle piece and being communicated with this recess, be located at this nozzle piece and the piezoelectric driving vibrator of this liquid that can periodically pressurize, inject and keep this liquid in the implantation tool of this recess, apply alternating current to the instrument of this piezoelectric driving vibrator, and the instrument that transmits to carry out liquid in conjunction with this implantation tool.When the liquid in this recess is vaporific droplet ejection through pressurization, can increase range of atomized flow by the nozzle piece with circular arc spray orifice.
United States Patent (USP) announces the 4th, 605, proposes a kind of ultrasonic applications in No. 167 in the nozzle piece of sprayer unit, and this nozzle piece that is applied to sprayer unit is to strengthen range of atomized flow by the spray regime that enlarges spray orifice.Yet, although utilize this kind prior art can strengthen range of atomized flow, but the spray regime of spray orifice is larger, the piezoelectric operated frequency that certainly will need higher-order, so also relatively increase and drive sprayer unit time institute energy requirement, and cause the excessive shortcoming of sprayer unit volume, and still can't improve the problem that atomized drop is piled up.
United States Patent (USP) announces the 6th, 089, proposes a kind of method and device that forms spray orifice in No. 698, and the method is to utilize the high-energy light beam of laser to carry out spray orifice towards the nozzle piece surface to make, and controls thus the emission direction of drop; Propose a kind of two-part processing procedure in Japanese patent laid-open publication gazette 2002-115627 number and form spray orifice in the nozzle piece surface, with the emission direction of control drop.Yet, use the wayward drop heading of this technology of Laser Processing, still there is the problem that range of atomized flow is narrow, atomizing effect is not good.
United States Patent (USP) announces the 6th, 235, then discloses a kind of manufacture method that is applied to the nozzle piece of sprayer unit in No. 177, is the spray orifice of convergent shape by forming upper surface and lower surface, so that drop can be along the central shaft of described spray orifice to ejecting rapidly; United States Patent (USP) announces the 7th, 040, then form central shaft to the spray orifice of symmetrical structure by etch process in No. 016, but, above-mentioned prior art is that this spray orifice that is applied in the nozzle piece of sprayer unit is designed to symmetrical structure, use this technology meeting restricting liquid drop vertical flight, still military order spraying area is subject to spray orifice position of opening and perforate scope.So, there is equally the defective in the aforementioned patent, so that cause atomizing effect not good.
As from the foregoing, because the technology of existing atomized liquid causes liquid perpendicular nozzle sheet to break away from jet atomization, order atomizing area and is subject to spray orifice zone, spray nozzle sheet and concentrates and spray many disadvantages such as causing the large and spray nozzle sheet processing procedure complexity of particle packing, sprayer unit volume, so that make that atomizing effect is not good, energy waste, be difficult to the product microminiaturization and be unfavorable for the industry utilization.
Therefore, how to propose a kind of nozzle piece of sprayer unit of the many disadvantages that overcomes background technology, real having become demanded the difficult problem that overcomes at present urgently.
