The specific embodiment
The present invention proposes a kind of atomising device and ultrasonic humidifier, and the floating atomizing enhancing section that arranges in the liquid above transducer all can produce better atomizing effect when making the liquid of transducer top be in any liquid level.Because the liquid of the present invention on transducer all can work when being in any liquid level of dynamic change, no longer need to keep fixing by the liquid level that the polycrystalline substance of cistern assembly is controlled on the transducer, thereby can break away from ultrasonic humidifier to the dependence of cistern assembly, realize the purpose of simplified structure and raising atomizing effect.
As shown in Figure 1, the atomising device that the present invention proposes comprises: the water tank 1 that is used for holding atomized liquid (such as water, medicament, pastil etc.), the bottom of this water tank 1 is fixedly installed transducer 2, and floating in water tank 1 atomizing enhancing section is set, and the upper surface of atomizing enhancing section changes with liquid level in the water tank 1 and is consistent with liquid surface.
This atomizing enhancing section comprises: guide barrel 3, the axial centre of the longitudinal center line of this guide barrel 3 and transducer 2 keep basically identical, guide barrel 3 axially on have columniform through hole, the bottom of this through hole is that inlet 31, top are fog outlet 32; And be fixedly connected with and swim in the buoyancy section 4 of liquid surface in the water tank 1 with guide barrel 3; liquid in the water tank 1 produces buoyancy to buoyancy section 4 swims in the water tank 1 whole atomizing enhancing section; and buoyancy section 4 provides equilibrant force for guide barrel 3; the longitudinal center line of through hole of guide barrel 3 and the longitudinal center line of transducer 2 are consistent; to guarantee that ultrasonic water column that transducer produces can be successfully enters through hole from the inlet 31 of guide barrel 3, in through hole, produce behind the liquid mist from fog outlet 32 ejections.
Along with liquid in the water tank 1 through the atomizing and be sent water tank 1 after, liquid reduces gradually in the water tank 1, thereby the liquid surface position in the water tank 1 also constantly descends, and atomizing enhancing section then swims in the liquid level that liquid surface follows in the water tank 1 automatically always and changes and dynamically change at its relative position in water tank 1.Atomizing enhancing section in motion process, because the radial diameter of buoyancy section 4 greater than the radial diameter of the limiting section 5 that is arranged on transducer 2 peripheries (wherein, the radial diameter of guide barrel 3 is less than the radial diameter of limiting section 5), thereby 4 limited 5 in buoyancy section limits and makes the bottom of guide barrel 3 can't touch transducer 2, can enter through hole from the inlet 31 of guide barrel 3 to guarantee ultrasonic water column.
In order to ensure buoyancy being provided and making as much as possible guide barrel 3 keep balance, so buoyancy section 4 needs to produce enough buoyancy.In general, buoyancy section 4 is made less than the material of fluid density in the water tank 1 by density, such as cystosepiment.
In conjunction with shown in Figure 2, in general, being shaped as of through hole is cylindrical.In addition, the shape of through hole can also be that the diameter of inlet 31 is large and taper shape or bottom that the diameter of liquid outlet 32 is less are columniform truncated cone for conical top near liquid outlet 32.
In another embodiment of the present invention, as shown in Figure 3, the bottom of through hole be larger cylindrical, the middle part of a diameter for hemispherical, the top consistent with lower diameter be less cylindrical of a diameter.Present embodiment can utilize the perforation pore structure, after ultrasonic water column enters through hole, the active force that the ultrasonic water column of hemispherical middle part balance of process through hole is produced guide barrel 3, thereby make atomizing enhancing section have the function of positioning oneself, the longitudinal center line of through hole and the longitudinal center line of transducer 2 are consistent substantially, and the enhancing section that guarantees to atomize is positioned at the top of transducer 2.
In conjunction with shown in Figure 4, in another embodiment, in the connection of the bottom of guide barrel 3 spacing ring 6 is set, the profile of this spacing ring 6 is any, and appearance and size is greater than the size of limiting section 5, when making liquid level in the water tank 1 low, conflict at the top of limiting section 5 by spacing ring 6 in the bottom of guide barrel 3, thus the enough distances of the bottom that makes guide barrel 3 and transducer 2 maintenances.
In addition, in conjunction with shown in Figure 5, sheathed one or more sleeves 3 ' on the outer surface/inner surface of guide barrel 3, and spacing ring 6 is fixed on the bottom of a sleeve 3 ' of outermost/interior, by sleeve 3 ' can be covert the length of adjustment guide barrel 3.Such as, when liquid level in the water tank 1 was low, this moment, a plurality of sleeves 3 ' were socketed in the outside of guide barrel 3 successively, and the move distance of ultrasonic water column this moment in atomizing enhancing section equals the axial distance of through hole in the guide barrel 3; If liquid level increases a little in the water tank 1, under the effect of buoyancy section 4, drive atomizing enhancing section and swim on the liquid level, band moving sleeve 3 ' slides in the outside of guide barrel 3, thereby the move distance of ultrasonic water column in atomizing enhancing section increased; When liquid level in the water tank 1 enough when high (be 20mm more than such as liquid level), under the Action of Gravity Field of spacing ring 6, all elongate to maximum length between guide barrel 3 and a plurality of sleeve 3 ', at this moment, the move distance of ultrasonic water column in atomizing enhancing section further becomes large, reach according to the different move distances of ultrasonic water column in atomizing enhancing section of automatically regulating of liquid level in the water tank 1 with this, strengthen atomizing effect, improve nebulization efficiency.
The atomising device that proposes in order to ensure the present invention has best nebulization efficiency, a guide cup 8 can be set in water tank 1, and the internal diameter of guide cup 8 is slightly larger than the radial diameter of buoyancy section 4, and the enhancing section that will atomize fluctuates along with liquid level changes take guide cup 8 as guiding among being arranged on guide cup 8.
In conjunction with shown in Figure 6, if use the larger water tank 1 of bore, be fixedly installed many (such as 2,3 or more) leads 9 in the bottom of water tank 1, make between the many leads 9 guiding area that forms be slightly larger than the profile of buoyancy section 4, move thereby buoyancy section 4 is limited between the guiding area that forms between the many leads 9.Perhaps, in buoyancy section 4 a plurality of pilot holes (not drawing among Fig. 6) are set, every lead 9 passes one of them pilot hole, make buoyancy section 4 according to lead 9 along with the liquid dynamic motion in the water tank 1.
The pore size of through hole lower end, namely the radial diameter of inlet 31 must less than the radial diameter of transducer 2, can obtain better atomizing and strengthen effect.Better, the radial diameter of inlet 31 be transducer 2 radial diameter 30%～70%, specifically need to select according to the power of transducer 2: when the power of transducer 2 hour, the lower limit of getting above-mentioned value range; When the power of transducer 2 is larger, the higher limit of getting above-mentioned value range.
In addition, the move distance of ultrasonic water column in atomizing enhancing section, the ultrasonic wave that equals transducer 2 generations is propagated 5 times～20 times of wavelength in the liquid of water tank 1.
In addition, when being applied in atomising device of the present invention on the humidifier, only needing increases a support that contains ultrasonic drive circuit, and atomising device of the present invention is arranged on the support, can form ultrasonic humidifier.
Take the mean value of the atomising device (such as ultrasonic humidifier) of the prior art atomization quantity when liquid level (being the liquid level of the liquid on the transducer 2) is respectively 50mm, 30mm, 20mm and 10mm as 1 o'clock, the atomization quantity of test atomising device of the present invention, the atomization quantity that test is obtained and the average atomizing amount of prior art compare, and obtain relative atomization quantity and list in shown in the table 1:
Table 1
The liquid level of the liquid in the table 1 on the 1st line display transducer, the atomising device of the 2nd line display prior art relative atomization quantity under each liquid level, and the relative atomization quantity of the 3rd line display the application atomising device under each liquid level.
The relative atomization quantity of above-mentioned table 1 all is power to be tested by the transducer 2 of 8W obtained.As can be seen from Table 1, when liquid level was 10mm, the application's nebulization efficiency was 130% of prior art; When liquid level was 20mm, the application's nebulization efficiency was 152% of prior art; When liquid level was 30mm, the application's nebulization efficiency was 225% of prior art; When liquid level was 50mm, the atomising device of prior art almost can't be worked, and the application's atomising device still can obtain.This shows that compared to existing technologies, the application not only all can work, and all can significantly improve atomization quantity when each liquid level when each liquid level.
And can find out from above-mentioned table 1: when adopting power to be the transducer of 8W, the liquid level of the liquid on the transducer all can obtain better nebulization efficiency when 10～50mm.The liquid level of the liquid on the transducer the experiment proved that, even also can obtain better nebulization efficiency when 80mm.
In addition, adopt atomizing enhancing section shown in Figure 5 in a disguised form to adjust the length of guide barrel 3 according to the liquid level in the water tank 1, it is transformable making the move distance of ultrasonic water column in atomizing enhancing section.At this moment, when transducer 2 to distance between the spacing ring 6 of atomizing enhancing section is respectively 95mm, 25mm, 15mm and 5mm, the atomization quantity of test the application's atomising device (still adopting power is the transducer of 8W), the mean value contrast of the atomization quantity that the atomization quantity that 4 kinds of distances is measured and these 4 kinds of distances are measured obtains corresponding relatively atomization quantity and lists in shown in the table 2:
Table 2
The 1st line display transducer 2 is to distance between the spacing ring 6 of atomizing enhancing section in the table 2, the relative atomization quantity of the 2nd line display the application's atomising device under each distance.As can be seen from Table 2, when transducer 2 when distance between the spacing ring 6 of atomizing enhancing section is between 5mm and 95mm, the application's atomising device all can work and obtain the higher atomizing effect of nebulization efficiency.Especially at transducer 2 when distance between the spacing ring 6 of atomizing enhancing section is between 15mm and 25mm, use the application's atomising device not only can obtain the higher atomizing effect of nebulization efficiency, can also obtain atomization quantity and relatively keep stable atomizing effect.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
