Definitions

  • This invention provides a liquid atomizer having an improved valve body.
  • a conventionally structured atomizer mostly like that shown in Figure 6, meant to atomize liquids contained therein, embodies a valve element which is composed, as a rule, of a pair of individually moulded, but correspondingly shaped hollow-set valve stubs 14a, 14b. Between such two semi-cylinders is mounted a steel ball check valve 14c to unite both together.
  • a ball type valve as used in an atomizer has several disadvantages that should be removed in order to make best use of an atomizer.
  • such a conventional ball valve 14c is typically made of rigid materials such that the presence of any kind of oxides adhered to its surface will add to the detriment of liquid-tight performance and eventually result in prejudicing the compression efficiency, further resulting in liquid drops being present in the resulting spray. Furthermore, in operation, the valve element 14 may easily get clogged in the wall surrounding the journal of the compression cylinder. Additionally, when a conventionally structured valve is subject to excessive externally induced shock, vibration or tilting stresses, the steel ball 14c will respond accordingly so that the high pressure liquids being compressed in the compression chamber will have a chance to enter the semi-cylinder by passing the interval gap existing between the steel ball 14c and the medium chamber 14b.
  • a main objective of the present invention is to provide an atomizer wherein the valve body is prepared differently in contrast to the conventional steel valve bodies so that it will not suffer from any external shocks and maintain a tightly closed condition, a relatively higher compression ratio so as to permit optimum atomization, and which should prove advantageous in respect of economy of production costs.
  • the plunger is provided with a passage hole in association with the spraying outlet of the nozzle head, and tops the end portion of a valve body in communication with the valve seat being formed in the central area of the passage hole, to the effect that a steel spring seated in the reduced area of the cylinder will bear the end portion of the valve body against the valve seat such that the valve element may come to a position for fitting into the cylinder.
  • a piston provided down the valve element will maintain a tightly bound engagement with the interior wall of the reduced diameter of the cylinder as the nozzle head is depressed.
  • the cylinder 1 comprises, in combination, a portion of larger diameter 1a and one of a reduced diameter 1b, the larger diameter 1a telescopingly engaged with a hollow-set piston 4 provided as part of the plunger 3 of the nozzle head.
  • the lower end of the reduced diameter 1b extends in the form of a suction tube 11 into the vessel 5.
  • the valve seat 1c lies between the larger diameter portion 1a and the reduced diameter portion 1b.
  • the nozzle 7 is in connection with plunger 3 through opening 6.
  • valve element 8 points upwards and forms a tight-bound valve body 8a together with valve seat 9 and is mounted central to the opening 6.
  • the valve element 8 is fitted in cylinder 1, the valve body 8a being borne against the valve seat 9 by means of spring 10 fitted in the reduced diameter portion 1b.
  • the lower part of the valve element 8 is structured such that the interior of the reduced diameter 1b will maintain a tight-bound engagement with the piston 8b upon depression of the nozzle head 2.
  • piston 8b is made from emollient resin materials having highly reliable water and ethyl alcohol tightness characteristics. Initial depression in operation will bring liquids A into cylinder 1 through suction, spraying of atomized particles with the invention is through fingertip depression of the nozzle head 2.
  • the plunger 3 will move downward, the valve seat 9 forming a part of the plunger 3 and being positioned on the valve body 8a will move the valve element 8 in conjunction therewith.
  • the hollow-set piston 4, also forming a part of the plunger 3, is telescoped within the larger diameter portion 1a in the downward displacement.
  • the underside of the valve element 8 is formed into a piston 8b which forms an enclosure with respect to the larger diameter portion 1a when slid into engagement with the reduced diameter portion 1b of the cylinder 1.
  • nozzle head 2 of the atomizer illustrated in Fig. 1 is screwed to lid 12 through threaded area 12a formed about the opening 5a of the vessel in relation to the cylinder 1.
  • flange 12b Surrounding the periphery of the plunger 3 is provided flange 12b meant to secure in tight-bound condition the liquids contained within.
  • Plunger 3 is connected to the nozzle head 2 overhead by passing through an aperture 13 about which flange 12b forms a depending skirt, such an arrangement ensures the absolute leak-free condition of the liquid once established in the vessel container.
  • Such a tight-bound means is provided on the flange 12b, as shown in Fig.
  • the spraying nozzle 7, as illustrated in Fig. 5, and structured hereunder, is provided with a plurality of gently curved grooves 7a extending radially to even better enhance the atomization effects.
  • the diversification through moment of torsion will be improved all the more advantageously when the liquids are ejected under high pressure, high speed conditions, since atomized outputs twirling in a curl are seen as tiny mist sprays.
  • the construction of the nozzle herein accounts but for one feature of the invention and by no means shall restrict the scope thereof.
  • the present invention makes possible the provision of a valve element having the characteristics of a regular pump and permitting convenient contact displacements up-and-down between the cylinder and plunger of an atomizer device having excellent atomization performance and defying imitation by like products by the provision of outstanding tight-sealing thereof to maintain advantageous compression efficiency such that the invention device will withstand shock and tilting that would prove detrimental to a regular atomizer structured otherwise.
  • An atomizer structure embodying the invention will not shed liquid drops when driven to yield atomized sprays such as occurs with conventional atomizers utilizing steel ball components within, and has been proven to be economically advantageous for mass production.
