Description
Technical field
The present invention is about a kind of spray generator, refers to a kind ofly to abate the noise, improve spray nozzle sheet service life especially, avoids the operating frequency drift and promotes the spray generator of nebulization efficiency.
Background technology
Spray generator on the market has two kinds of pressure type and mechanical concussion formulas now.The former utilizes pressure differential with the atomization of liquid, though can the big effect of atomized amount, shortcoming is that particle noise big, that need the machine that improves pressure and pressure type is bigger etc.With medical water smoke generator, do not need so big atomization quantity, and the requirement of granular size is taken much count of, so the spray generator of pressure type is not suitable on the medical application gradually.Medical water smoke generator in recent years is based on machinery concussion formula, and major part is the ultrasonic vibrations that produces with piezoelectric this liquid that atomizes, but this atomizing type has its shortcoming, and for example: power consumption is big, need fan that fog direction of transfer etc. is provided.
And in the spray generator based on piezoelectric, except the mode of above-mentioned ultrasonic atomizing, the spray generator that the spray nozzle sheet of arranging in pairs or groups in addition in addition uses.Added after the spray nozzle sheet, can reduce the electric energy of use greatly, and, made granular size controlled through the effect in aperture.Relevant at present patent or product roughly can be divided into two classes: a class is to utilize the piezoelectric vibrations that liquid is extruded spray orifice to form fog, and another kind of is to utilize piezoelectric vibrations spray nozzle sheet, makes and initiatively pushes liquid, and this liquid is discharged from spray orifice and formed 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; And the latter's spray nozzle sheet is the element that initiatively shakes, and easily has tired problem to take place.Have noise, spray nozzle sheet vibration area Da Yi during the empty shake of the phenomenon that it causes such as no liquid and reduce problems such as service life, operating frequency meeting drift and nebulization efficiency after the sky shake are low.
The general spray generator 60 that initiatively shakes the atomising device of element, comprise an oscillating element 70 and spray nozzle sheet 80, as shown in Figure 6, this spray nozzle sheet 80 drives aforementioned spray nozzle sheet 80 vibrations by this oscillating element 70, because aforementioned spray nozzle sheet 80 produces extrusion effect by vibration to liquid, liquid is discharged by aforementioned spray orifice 81, and form fog.
Yet in the process of this atomizing,, make when vibrations because of this spray nozzle sheet is bonded on this oscillating element, the integral body of this spray nozzle sheet can shake together, has increased the area of spray nozzle sheet vibrations, and has caused spray nozzle sheet that tired problem is easily arranged, and increase the load of spray nozzle sheet simultaneously, and make nebulization efficiency low.
In sum, the reduction of vibrations area, the service life of spray nozzle sheet are increased and the raising nebulization efficiency, and avoid the operating frequency drift, problem demanding prompt solution in the real industry for this reason.
Summary of the invention
The object of the present invention is to provide a kind of spray generator that can abate the noise.
Another object of the present invention is to provide a kind of spray nozzle sheet spray generator in service life that improves.
Another purpose of the present invention is to provide a kind of spray generator of avoiding the operating frequency drift.
A further object of the present invention is to provide a kind of spray generator that promotes nebulization efficiency.
Be the spray generator that achieves the above object, in order to the liquid that atomizes, and be applied to an atomising device with accommodation space and open-work, this spray generator comprises: an oscillating element, corresponding aforementioned open-work are provided with one first perforation; One spray nozzle sheet, corresponding aforementioned first perforation is provided with a plurality of spray orifices, and links with aforementioned oscillating element; An and structural detail, a plurality of spray orifices of corresponding aforementioned spray nozzle sheet are provided with one second perforation, and link with aforementioned spray nozzle sheet, aforementioned spray nozzle sheet is fixed between aforementioned oscillating element and the structural detail, and the oscillating element after will making up, spray nozzle sheet and structural detail place the accommodation space of aforementioned atomising device, produce vibration kinetic energy by aforementioned oscillating element, produce atomizing so that liquid sees through the spray orifice of this spray nozzle sheet.
Aforementioned body further can comprise a water filling port, in order to aforementioned liquid to be atomized is injected in the aforementioned cavity.And aforementioned oscillating element is a piezoelectric patches.The aforementioned structure element is made by plastic material.
Wherein, aforementioned oscillating element is provided with an elastomer, and aforementioned elastomeric material is selected a plastic cement material for use, and aforementioned spray nozzle sheet utilizes viscose to be fixed between aforementioned oscillating element and the structural detail.
The corresponding aforementioned through-hole position of aforementioned oscillating element is provided with one first perforation, and corresponding aforementioned first perforation place of aforementioned spray nozzle sheet is provided with a plurality of spray orifices, and the corresponding aforementioned a plurality of spray orifices of aforementioned structure element are provided with one second perforation.The aperture of aforementioned second perforation is less than the aperture of aforementioned first perforation.
And that aforesaid second perforation can be is one bowl-shape, rounding shape or chamfer shape.
According to such scheme, the present invention is significant with respect to the effect of prior art: spray generator of the present invention is when action, can limit the vibration area of spray nozzle sheet, make originally to the atomizing action not have help arround the zone stop to shake, and allow concentration of energy in the central area, thus, atomization rates can promote, also comparatively economizing can, and spray nozzle sheet of the present invention increases the reinforcement of structural detail compared to the spray nozzle sheet of prior art, and overall construction intensity is increased, making can be because of shaking the problem that comes off with glue that produces repeatedly arround the spray nozzle sheet, and then solve the problem of infiltration, and spray nozzle sheet is limited in the center because of vibration region, the zone that is subjected to fatigue effect is also less, therefore the spray nozzle sheet situation of breaking when sky shake is difficult for generation, and makes the long service life of spray nozzle sheet.
