Definitions

  • the invention relates to an ultrasonic liquid atomizer with a piezoelectric vibration system, excitation electronics, a power supply, a switch, a liquid reservoir and a valve for controlling the liquid supply to the piezoelectric vibration system.
  • spray cans contain a pressurized propellant and the liquid to be sprayed, generally a cosmetic.
  • the propellant gas sprays the liquid and carries away the aerosol that forms.
  • Such spray cans pollute the environment due to the released propellant gas.
  • most of the propellants suitable for this purpose damage the earth's ozone shell.
  • the sprayed cosmetics such as hair sprays, hair fixators and the like also strain the respiratory tract, in particular those who are professionally concerned with it.
  • a liquid atomizer for medical purposes in which a liquid in a liquid storage container is fed to a piezoceramic vibration system and is atomized there.
  • the aerosol that forms is carried away by the air flow from a built-in blower.
  • the aerosol generated is carried along by the generated air flow and transported over a longer distance.
  • a battery-operated liquid atomizer is preferably known for inhalation purposes.
  • This liquid atomizer is handy - it has the dimensions of a cigarette box - and carries an atomizer funnel at one corner under a cap and behind this atomizer funnel a piezoelectric vibrating system.
  • the radiation surface of the piezoelectric oscillation system is wetted by the liquid dispenser with the liquid to be atomized via a pan.
  • the housing of the liquid atomizer also contains the excitation electronics for the piezoelectric oscillation system and a switch via which the excitation electronics can be switched on.
  • This liquid atomizer which does not require a blower, is used as a portable inhalation device. With the cap removed, the patient's mouth is held in front of the atomizing funnel and the atomized aerosol is inhaled. The aerosol is sucked into the patient's mouth and respiratory system by the air flow.
  • the invention is based on the object of showing a way in which, in particular, cosmetic articles such as hair sprays, hair fixers and the like can be applied in an environmentally friendly manner.
  • cosmetic articles such as hair sprays, hair fixers and the like can be applied in an environmentally friendly manner.
  • environmentally harmful propellants should be avoided.
  • a particularly expedient embodiment of the invention is achieved if the tubular device attachment can be plugged onto the atomizer housing. This allows several device attachments for different applications to be provided for one and the same ultrasonic liquid atomizer. This is also a prerequisite for being able to optimally adapt the tubular device attachment to a particular application.
  • a particularly environmentally friendly transport of the aerosol to the application site and at the same time particularly economical use of the cosmetic agent is achieved if, in a particularly advantageous development of the invention, the radiation surface of the piezoelectric oscillating system can be electrically charged.
  • the aerosol particles leaving the piezoelectric vibrating system can be charged electrostatically.
  • a reliable supply of the radiation surface of the piezoelectric oscillation system with the liquid to be atomized is achieved when the piezoelectric oscillation system in the embodiment of the invention has a central bore for the supply of liquid.
  • the tubular device attachment can also have a smaller diameter, which in many cases benefits the easier application of the aerosol.
  • the radiation surface of the piezoelectric oscillation system can be shaped approximately flat in an expedient embodiment of the invention.
  • the ultrasound vibrations of the radiation surface of the piezoelectric oscillation system impart a pulse to the aerosol particles essentially in the direction perpendicular to the radiation surface, so that an approximately cylindrical jet of aerosol particles flows from the radiation surface.
  • the radiation surface of the piezoelectric oscillation system can be designed as a truncated cone in a further embodiment of the invention.
  • the result of this is that the aerosol particles flow away in a more divergent manner and thus a larger surface is contacted with the aerosol at a given distance from the application surface.
  • the ultrasonic liquid atomizer 1 has an approximately pistol-shaped housing shape due to the best possible position in the hand of the user. It comprises an approximately cigarette-box-sized base housing 2 in which the power supply 4, the excitation electronics 6 and a switch which can be actuated via a release button 8 are accommodated. At the upper end of this base housing 2, at right angles to its longitudinal axis, a pluggable tubular device attachment 12 can be seen, which contains the piezoelectric vibration system 14. In addition, an attachment 16 with a liquid container 17 or a liquid cartridge can be plugged onto the upper side of the base housing 2.
  • the base housing 2 is provided on its one long, narrow side with corrugations 18, 19, 20, 21 for the four fingers of a holding hand.
  • the tubular device attachment 12 is slightly retracted in its front open end. As can be seen in FIG. 1, it carries the piezoceramic oscillating system 14 with a piezoceramic 22, a conical oscillating element 24 fastened to the piezoceramic with an integrally formed flat, plate-shaped radiation surface 26.
  • the piezoelectric oscillating system 14 is installed in the tubular device attachment 12 in such a way that the flat radiation surface 26 is arranged only a few millimeters behind the opening 28 of the tubular device attachment 12. It contains a central bore 30 and is connected in a manner not shown here via a liquid line 32 and a valve 34 to the liquid reservoir 17 in the attachment 16.
  • the ultrasonic liquid atomizer is taken in the hand in such a way that the fingers lie in the corrugations 18, 19, 20, 21 of the base housing 2 and the index finger rests on the release button 8.
  • the ultrasonic liquid atomizer 1 can now be directed against the application surface, for example the hair of the customer, with the opening of the tubular device attachment 12.
  • the trigger button 8 is actuated with the index finger, the excitation electronics 6 are first switched on and the piezoelectric oscillation system 14 is thus excited to oscillate.
  • the valve 34 is opened so that the liquid, such as. B. hair set, hair tonic or the like, from the liquid container 17 through the central bore 30 of the piezoelectric vibration system 14 on its radiation surface 26.
  • the liquid is thrown from there in the form of very fine droplets at right angles to the radiation surface 26.
  • An impulse is transmitted to the detached aerosol particles, which enables them to fly 5 to 10 cm.
  • the aerosol particles are not thrown out diffusely into the room, but can be aimed directly at the customer's hair or a suitable application surface.
  • the valve 34 is first closed and then the excitation electronics 6 are switched off. This will ensure that liquid particles still on the radiation surface 26 fly away completely and do not gradually dry out there and contaminate the radiation surface over time.
  • the oscillating element 24 itself or the surface of the radiation surface 26 of the oscillating element 24 is designed to be electrically conductive and to an electri cal high-voltage source 27 connected in the base housing 2.
  • an electri cal high-voltage source 27 connected in the base housing 2.
  • the electrical high-voltage source 27 is to be connected in series via an additional switch 36 to the switch 10 actuated by the release button 8 for the piezoelectric vibration system.
  • the switch 36 for the electrical high-voltage source 27 is now switched on, the electrical high-voltage source 27 is also switched on when the trigger button 8 is actuated together with the piezoelectric oscillating system 14, so that the radiation surface 26 is electrically charged with respect to the surroundings.
  • the application surface such as, for. B. the customer's hair.
  • the tubular device attachment 12 is now directed onto an application surface, all the emitted aerosol particles are collected by this application surface. Any air pollution caused by freely floating aerosol particles can be reliably avoided. This is particularly important because many of the cosmetics used, such as. B. hair set, should not be inhaled if possible for health reasons.
  • the exemplary embodiment in FIG. 2 shows a piezoelectric oscillation system 40 with a shape that differs from the exemplary embodiment in FIG.
  • the piezoceramic 42 is attached to the surface at the rear end of the oscillating element 44.
  • the oscillating element 44 is essentially cylindrical. It only contains a circumferential semicircular notch 46 behind the radiation surface 48. This shape Given a more plane-parallel vibration of the radiation surface 48 is achieved and an aerosol flow is generated, which is essentially cylindrical and flows perpendicularly from the radiation surface 48.
  • Also in this piezoelectric vibration system 40 in a central bore 29 for the liquid supply and the radiation surface 48 of the vibrating element can be made electrically conductive.
  • the exemplary embodiment in FIG. 3 shows a further piezoelectric vibration system 50, in which the piezoceramic 52 is in turn placed on an essentially conical vibration element 54.
  • the emitting surface 56 is not flat, but is of truncated cone shape.
  • the main radiation power is emitted at the edges of the radiation surface 56 and this radiation power is in turn directed essentially perpendicular to the radiation surface.
  • the piezoelectric oscillation system 50 according to FIG. 3 also generates an essentially conical aerosol flow. This is particularly suitable for large-area application areas.
  • there is a central bore 31 for the liquid and the radiation surface 56 can be made electrically conductive and connected to an electrostatic high-voltage source.
  • each of these piezoelectric vibration systems 14, 40, 50 is housed in its own tubular device attachment 12, which can be plugged onto the base housing 2 if necessary, can be achieved by changing the radiation profile of the ultrasonic liquid atomizer 1 very quickly. This can be flexibly adapted to the respective work situation.
  • the ultrasonic liquid atomizer 1 It is a particular advantage of the ultrasonic liquid atomizer 1 that it is not only easy to handle and its radiation characteristics can be changed, but that it can be used above it in addition, the use of environmentally harmful propellants, such as spray cans, is avoided. In addition, it is a particular advantage of this ultrasonic liquid atomizer that the aerosol produced is not widely scattered by any air or gas flow, but rather can be radiated directly onto the application focus. Finally, with additional electrostatic charging of the aerosol, any contamination of the air in freely floating aerosol particles can be reliably prevented.
