Definitions

  • the invention regards a device that is able to nebulize liquid substances and solutions.
  • nebulizers are known, which, however, do not always prove satisfactory as regards their efficiency and ease of use.
  • a further drawback lies in the fact that known nebulizers can induce alterations of the nebulized liquid, for example of a thermal type or due to the use of propellents.
  • the purpose of the present invention is to overcome the drawbacks of nebulizers of a known type and to propose a high-efficiency nebulizer that is easy to use and able to nebulize the liquid without inducing alterations either from the thermal standpoint or ones due to the propellents used.
  • the nebulizer according to the invention has a high efficiency and ease of use, and is able to nebulize the liquid in a natural way without inducing alterations either from the thermal standpoint or ones due to the propellents used.
  • FIG. 1 shows a perspective view from the left of the device according to the invention
  • Figure 2 is a schematic view of the device, which highlights the path followed by the liquid up to its nebulization in the atmosphere;
  • Figure 3 shows schematically the control diagram the device.
  • the nebulizer comprises a flask 4 containing an amount of liquid substance to be nebulized.
  • a top 3 having a dispenser 6 connected to the liquid via a tube 9 and provided at the top with a nozzle 10 for delivery of the nebulized liquid.
  • a Venturi-effect system of ducts 14 having an inlet 15 for compressed air connected by means of a pipe 19 to a corresponding air outlet 18 of a compressor 2.
  • the flask is filled with the liquid 16 that is to be nebulized and the top 3 is inserted so as to prime the tube 9 in the liquid 16.
  • the compressor is started up, the compressed air leaving the air outlet 18 enters the top through the air inlet 15 and traverses the system of ducts 14, causing a negative-pressure by the Venturi effect.
  • the system of ducts 14 comprises a duct with decreasing section 20, which is traversed by the air coming from the inlet 15 and gives out into a negative-pressure chamber 21, which is in turn connected to the priming tube 9.
  • the liquid 16 is recalled into the chamber 21, converges with the flow of air leaving the duct 20 and is nebulized thereby coming out in a nebulized form 23 from a hole 22 in the chamber 21 and invading the internal compartment 24 of the top 3.
  • the liquid 16 is recalled and rises in the tube 9 up to the system of ducts 14 of the top 3, where the turbulence encountered causes decomposition of the liquid into microparticles, which nebulize and exit from the delivery nozzle 10.
  • the compressor 2 is electrically supplied and the nebulizer is provided with an electronic control circuit 17 ( Figure 3) operatively connected to the electrical supply 5, to the compressor 2 and to the dispenser 6.
  • an electronic control circuit 17 Figure 3 operatively connected to the electrical supply 5, to the compressor 2 and to the dispenser 6.
  • the nebulizer can moreover be housed inside a boxlike containment casing 7, provided with a hole 8 communicating with the delivery nozzle 10.
  • the nebulizer described above is able to transform from the liquid state to the gaseous state a liquid, which thanks to the compression of air coming from the compressor undergoes, owing to the conformation of the flask 4, a decomposition into tiny droplets, which are set in suspension in the air and are forced out of the dispensing flask reaching the outside to diffuse into the atmosphere and perform treatment thereof according to the active principle present in the liquid.
  • the entire operating cycle is not subject to thermal action or action of propellents other than air so that the nebulized liquid does not undergo any alteration and is not denatured.
  • the electronic circuit or a PLC, manages operation of the device to decide the time for delivery, the starting time, and the duration.
  • the device can function with different liquids, contained in removable flasks set either inside or outside the container 7 and possibly connected thereto via a system provided with air-delivery pipes .
