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.
  • Both GB-A-2110771 and FR-A-2181198 disclose a hand-held pump-type dispenser in which depression of a nozzle causes increasing pressurisation of a fluid in the dispenser to a point at which the pressure forces open a valve in a passage connecting the fluid and the nozzle to allow pressurised fluid to exit the nozzle.
  • 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.
  • a pump-type atomizer comprising a nozzle in communication with one end of a first passage member, the first passage member comprising a valve seat, the other end of the first passage member communicating in a fluid-tight manner with one end of a second passage member and being mounted for slidable movement relative thereto, a valve member being mounted within the second passage member, the valve member being contactable in a fluid-tight manner with the other end of the second passage member or with the valve seat, and biassing means for urging the valve member away from the other end of the second passage member and toward the valve seat, wherein the second passage member comprises an upper portion and a lower portion with a maximum diameter less than the diameter of the upper portion, characterized in that the lower portion has a tapered configuration such that its diameter decreases in a direction away from the upper portion.
  • the underside of the cylinder, having a reduced taper diameter, is engaged in the liquid container.
  • 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.
