Definitions

  • a cylindrical liquid receptacle Spaced coaxially within the housing by several axially extending vanes is a cylindrical liquid receptacle having a frustoconical end portion with a tubular extension of small fluid-flow cross section extending into the housing extension.
  • the blower exerts pressure on the liquid in the receptacle to drive it through the constriction at the bottom of the receptacle, an airstream flowing around the receptacle entrains these droplets toward an impact (impingement) surface formed at the end of the handpiece to atomize the larger droplets and form a mist which is ejected through the orifice of the endpiece.
  • the present invention relates to a spraying apparatus particularly adapted for household use for cosmetic, medical, or dental purposes and, more particularly, to a spray .device and method for dispensing a lowwiscosity liquid (e.g. water or an aqueous solution) in the form of an atomized jet.
  • a lowwiscosity liquid e.g. water or an aqueous solution
  • Such sprayers for household use generally comprise a small air compressor, a small liquid reservoir, a nozzle arrangement adapted to held in the hand, and two generally coaxial flexible conduits connecting the nozzle to the reservoir and compressor.
  • the airstream of one conduit encounters the liquid emerging from the other at a specially designed nozzle and breaks up the liquid to form droplets which emerge at the nozzle.
  • This type of apparatus has several disadvantages. Firstly the apparatus is quite noisy, the compressor usually being a small pump or blower which must develop considerable pressure, expensive, difficult to handle and prone to breakdown.
  • a more specific object is to provide an apparatus of the above-described general type which overcomes the abovementioned disadvantages, e.g., which is inexpensive and silent while being easy to handle.
  • a small axial blower is fastened to a wall and a housing can be screwed onto the base of this blower and hang there.
  • a receptacle is received within the housing with a space all around between it and the housing so that the air pressure generated by the blower is exerted both on the liquid in the receptacle to drive it out through an aperture in its extreme lower end, and forms an airstreamaround this receptacle.
  • Both the housing and the receptacle are of similar shape, i.e., cylindrical with a frustoconical lower end terminating in a tubular extension, and are nested coaxially one within the other with circumferential spacing and the extension of the receptacle extending into that of the housing.
  • the receptacle is removable filling and is provided with flat spacing elements which extend radially outwardly and axially along the receptacle.
  • the endpiece mounted on the flexible tube fitted over the extension of the housing is advantageously a blind tube having a radially or laterally opening orifice near its end wall.
  • this tube can be fitted with bristles and may constitute a toothbrush.
  • the invention is able to accomplish satisfactory transmission of a liquid-in-gas dispersion with only partial agglomeration of liquid droplets, through a single conduit, by virtue of the combined effect of the pressure drive of the liquid to the point at which the initial dispersion of liquid in gas is formed, and subsequent impingement or impact atomization.
  • FIG. 2 is an axial sectional view through the receptacle of the present invention.
  • FIG. 3 is a cross section according to the line llIIll of FIG. 1.
  • the spraying apparatus has, as shown in FIG. 1, an axial blower 1 attachable to a wall by means of a bracket 13 and into which a cylindrical housing 2 is threaded by means of a threaded region 14.
  • the housing 2 has a frustoconical end portion and a tubular extension 6 with a flexible conduit 7 extending from the base 6 of the housing 2 to an endpiece 8.
  • FIG. 2 also shows how the extension 5 can be sitted with a small valve 16 to adjust the flow thercthrough.
  • the endpiece 8 is formed as a blind tube having a longitudinal axis a and an internal end wall 9. An orifice 10 is formed in the side of this tube 8 adjacent the flat wall Q. This endpiece 8 is simply press fitted in the end of the tube 7, as the tube is fitted over the extension 6 of the housing 2. For use as an irrigated toothbrush, the endpiece 8 is provided with bristles 12.
  • the receptacle is filled with whatever liquid is to be sprayed, e.g., mouthwash, alcohol, disinfectant, astringent, and is placed in the housing 2 which is then screwed onto the base of the blower l.
  • a plug 15 is connected to a source of electricity or a switch is actuated to start the blower I going.
  • This blower I then exerts gas pressure on the entire surface 12 of the body of liquid in the receptacle 4 and thereby causes it to spurt or drop out of the extension 5 and form droplets 11.
  • An airstream produced by the fan 1 also passes axially down all around the receptacle 4 and is compressed and entrains the droplets 11 to drive them through the tube 7. This airstream completely surrounds the extension 5 at its tip where is defines the aperture through which the droplets 11 pass, so that these droplets are very effectively entrained.
  • said conduit means adjacent said orifice forming an impact surface transverse to said path for intercepting said droplets and atomizing same, said conduit means further guiding the airstream out through said orifice to entrain the mist produced at said impact surface, said receptacle having an extreme lower end formed with said apenure, said conduit means including a housing receiving said receptacle, a flexible conduit having one end connected to said housing adjacent said aperture, and an endpiece connected to the other end of said conduit and formed with said surface, said housing and said receptacle each having a central axis and being of uniform cross section, said receptacle being spacedly received within and coaxial with said housing.
  • said endpiece is adapted to be held in the hand and constitutes a blind tube having a longitudinal axis and a radial opening constituting said orifice, the internal end wall of said tube being flat and perpendicular to said longitudinal axis and forming said surface.
