  • Preferred Embodiment of the Invention
  • [0017]
    An apparatus for ultrasonic atomization of liquids comprises an ultrasonic radiator 1 (Fig. 1) with a concentrator 2 (Figs. 1, 2). The radiator 1 carries a main bearing sleeve 3, whereas provided at the concentrator 2 and at its end portion 4 are additional and auxiliary bearing sleeves indicated by 5 and 6, respectively. Arranged along the geometrical longitudinal axis 7 of the concentrator 2 are three tubes 8, 9, 10 (Fig. 1) for feeding the liquid, each such tube communicating with a respective vessel 11, 12, 13 containing liquids. The tubes 8, 9, 10 (Fig. 2) rest on the main bearing sleeve 3. Free ends 14, 15, 16 (Fig. 1) of the respective tubes 8, 9, 10 extend through the body of the sleeve 5, and are adapted to movably enter ends 17, 18, 19 of the corresponding hollow rods 20, 21, 22. The body of the sleeve 6 has three radial passages 23, 24, 25 (Figs. 2, 3) with the inlet hole of each such passage communicating with another end 26, 27, 28 of the corresponding hollow rod 20, 21, 22, their outlet holes being provided at an inner surface 29 of the sleeve 6. The end portion 4 of the concentrator 2 has grooves 30, 31, 32 (Figs. 3, 4) extending along its axis 7 and equal in number to the number of tubes 8, 9, 10 (Fig. 1), each such groove communicating with the outlet hole of the corresponding passage 23, 24, 25 (Figs. 3, 4) of the sleeve 6. Secured in the body of the sleeve 5 (Fig. 1) are three valves 33, 34, 35 for controlling the flow rate of the liquid, each such valve communicating with the respective tube 8, 9, 10.
  • [0018]
    According to another embodiment of the concentrator 2 of the apparatus for ultrasonic atomization of liquids, each groove 36, 37, 38 (Fig. 5) at its end portion 4 extends about a helical line. Otherwise, this construction of the concentrator 2 is similar to one described with reference to Figs. 1 and 2.
  • [0019]
    The proposed apparatus for ultrasonic atomization of liquids operates in the following manner.
  • [0020]
    Signals generated by an ultrasonic generator (not shown) are conveyed to the ultrasonic radiator 1 (Figs. 1, 2) to induce ultrasonic oscillations therein.
  • [0021]
    From the radiator 1 the oscillations are transmitted to the concentrator 2 to be emitted from its end portion 4. At the same time, the liquids, such as liquids of different properties, are convyed from the vessels 11, 12, 12 along the tubes 8, 9, 10 to the portion 4 of the concentrator 2. According to one specific feature of the invention, the use of several tubes 8, 9, 10 affords atomization of such unlike liquids which are preferably not to be mixed together prior to atomization.
  • [0022]
    When it is necessary to mix different liquids, the valves 33, 34, 35 (Fig. 1) act to control the feed of such liquids along the tubes 3, 9, 10 in preferred proportions. This arrangement of the valves 33, 34, 35 allows to increase the field of vision of the surface being treated and makes the apparatus more convenient in handling. The liquids flow from the tubes 8, 9, 10 and along the corresponding hollow rods 20, 21, 22 to the radial passages 23, 24, 25 (Fig. 3) of the auxiliary bearing sleeve 6. From the outlet holes of the passages 23, 24, 25 the liquids are conveyed to the corresponding groove 30, 31, 32 (Figs. 3, 4) of the concentrator 2. This feature of the invention prevents leaks of the liquids and excessive consumption rate thereof during atomization.
  • [0023]
    Arrangement of the grooves 30, 31, 32 (Fig. 5) of the concentrator 2 about a helical line allows to intensify the atomization process.
  • [0024]
    The present invention makes it possible to simplify operation of the apparatus.
  • [0025]
    In addition, the invention affords a saving in the consumption of liquids being atomized.
  • Industrial Applicability
  • [0026]
    The invention can be used for obtaining aerosols and mist sprays, for example, when applying liquids to various surfaces.
  • [0027]
    The invention can also find application in internal combustion engines, fuel injectors, and the like.
