J. ZUBLIN ATOMIZER Dec. 16, 1952" Filed June 2, 1949 INVEN OR ouuus ZUBLIIV Patented Dec. 16, 1952 ATOMIZER Julius Ziiblin, Glarisegg-Steckborn, Switzerland Application June 2, 1949, Serial No. 96,757 In Switzerland January 31, 1949 3 Claims.
The present invention relates to an atomizer for liquids with which air is driven through a jet by means of a pump into which jet a pipe for liquid opens. The invention has as one of its principal objects the provision of a container for liquid which is interchangeably arranged on the atomizer and provided with means which automatically bring the container in connection with the pipe line for the liquid on the atomizer and which closes said container automatically on its being removed from the atomizer.
Other objects will be apparent from the detailed description of several embodiments of the present invention which will now be described by way of example with reference to the accompanying drawing in order that the invention be better understood and readily carried into effect.
Fig. 1 shows a first embodiment of the invention, showing the atomizer and liquid holding container in longitudinal section,
Fig. 2 shows on an enlarged scale a second embodiment of the invention with atomizer, partly in section, and
Fig. 3 a third embodiment of the invention with atomizer, partly in section.
According to the first embodiment of the invention shown in Fig. 1 a jet I is provided in the jet body 2. The jet duct is in connection with an air pump 3 consisting of a stationary hollow cylinder 4 and a piston 5 arranged therein for longitudinal displacement, said piston being provided with a rubber seal 6. An air inlet pipe I is in connection with the inside of the air pump 3, said inlet pipe at the same time serving as a guiding means for the piston 5 and as a piston rod. The free end of the air inlet pipe rests against a seal 911, secured to the operating lever 9 which is under the action of a spring 8 contained within the pump. The operating lever 9 is arranged pivotally about a pin It! in a housing, said housing having the shape of a handle and enclosing the air pump 3, between the jet body 2 and the air pump 3 being interposed a seal I2. A compression spring I3 forces the operating lever 9 into the position of rest shown in the drawing, a stop M on the housing I I limiting the outward movement of the lever 9.
A conduit or pipe I5 for liquid opens into the jet I, said pipe being formed of a short extension pointed or bevelled at its outer end to thereby facilitate projection of said tube into the interior of a bottle I6 serving as a container for liquid. The extension is of a length sufficient to permit dispensing of substantially the entire contents of the receptacle or bottle I6 under the action of the pump. The bottle is located above the jet with its opening provided in the neck downwardly directed (upside down position) so that the liquid contained therein can reach the jet I through the short tube piece I5 when the pump is being operated. On the neck of the bottle a closure sleeve I'I provided with a lid is detachably secured by means of a screw connection, said sleeve having a suitable opening in the lid to permit the entry of the pipe I5 for the liquid. The bottle I6 is capable of being inserted in the'axial direction with the cylindrical wall of the capsule ll into a suitable guiding means I8, said means being a cylindrical hollow body screwed on to the jet body 2. The elastic diaphragm I9 made e. g. of soft rubber is clamped between the edge of the neck of the bottle and the sleeve I! and serves on the one hand as a seal between the bottle I6 and the sleeve I1 and on the other hand for closing the opening of the bottle on removal of the bottle from tubular piece I5. Behind the opening of the sleeve lid the diaphragm I9 has a fine slot orifice which is formed by the piercing action of the pointed end of pipe or tubular piece I5 when the bottle is fitted on to the atomizer for the first time and which normally closes under the action of the elasticity of the diaphragm I9.
On pressing on the outside of the operating lever 9 with the thumb of the hand gripping the handle the air present in the air pump is forced through the jet I (forming dispensing and atomizing means) whereby a small quantity of liquid is sucked from the bottle and is atomized in the air stream. Due to the described arrangement of the bottle above the jet, the weight of the liquid assists the discharge of the liquid when atomizing. During the extraction of the liquid a vaccum is formed in the container which causes the corresponding volume of air to be sucked through the pipe line I5 immediately on cessation of the air flow through the jet in order to create an equalization of the pressure. On releasing the lever 9 it is rapidly moved back into its position of rest by the action of the spring I3, whereby the seal 9a is lifted from the air inlet pipe I. The air flows through it into the pump and the piston can slide back again under the action of the spring 8. On renewed pressure on the operating lever 9 the seal 9a closes the air inlet pipe 1, so that the air in the pump cylinder is forced to escape through the jet.
The combination atomizer and dispenser according to the invention requires neither an actual suction pipe nor a special air inlet orifice in the container for liquid.
If the container l5 for the liquid is to be removed, be it because the atomizer is not being used or for the purpose of refilling the bottle or replacing it by another one containing a different liquid, the container I6 is simply withdrawn in the direction of the neck of the bottle upwardly out of the guiding means 18. In doing this the pipe line [5 for the liquid slides out of the closable orifice of the diaphragm [9 which orifice immediately closes due to the elasticity of said diaphragm, and thus the liquid is prevented from flowing out. The operation of fitting a bottle to the atomizer takes place in the most simple manner in the inverse sequence. The closing action of the orifice of the diaphragm holds the fitted bottle securely by pressure on the pipe line for the liquid in the guiding means it.
For refilling a bottle i6 which has become empty, said bottle is removed from the atomizer whereupon the sleeve i! can be unscrewed.
In Fig. 2 a somewhat simpler example of em bodirnent of the-atomizer pump is shown. Whilst the jet and the container for the liquid are executed similarly to the first example just described, the guiding means 58 serving as a carrier for said container constitutes a bore in the jet'body 2. In this example the piston 5 of the air pump 3 is operated by hand and by exertion of pressure by means or one finger, the
inlet of'the air suction pipe 1 being simultaneously closed by the finger pressing on the piston. The airsu'ction' pipe 'I again serves aspiston rod which piston rod "is'slidably mounted in a passageway 2a of the jet-body'2. lThe air in the pump. cylinder 4'isforced through alongitudinal recess la, arranged on the outside of the pipe 1" into the jet; and the air suction through the pipe 7 on releasing the piston 5 similarly finds its way into the air pump through'this recess la;
The third embodiment shown in Fig. 3 distinguishes from the first two examples, in which the axis of motion of the piston of the pump lies in the direction of discharge of thejet, by having a pipe line 26 bent at-right' angles between the jet landthe air pump 21, 22. Expediently the pipe line 20 is bent'in such a manner that the pump is operated by a downward pressure. The pump consists of a hollow cylinder 22 arranged for'axia-l displacement in the housing 2'! in which cylinder a pumppistoninot shown) is fixedly arranged; The cylindrical body serving as guide means l8 for the insertion of the container l6 holding the liquid is formed of a single piece together with the jet body 2 in this example.
As the container for the liquid a bottle made of transparent materialmay be employed, which bottle is provided with graduation markings for checking the amount of liquid withdrawn. For the same purpose a marker capable of being axially displaced can be arranged around the bottle which marker is set before starting the atomizing to the height at which the level of the liquid is to be chosen upon the completion of the atomizing operation.
