Definitions
- a mist generator comprises a generally closed vessel formed with an elastically deflectable wall and with an aperture in its side.
- An inverted-bottle filler is provided to maintain a liquid level in the vessel below the wall and below the aperture and a piezoelectric transducer having a concave upper surface focused on the liquid level is provided in the vessel below the liquid level so as to vaporize this liquid and form a cloud of mist in the vessel
- a motor is provided to periodically deflect the vessel wall and expel] the cloud of mist from the vessel.
- This motor can have a lever actuated by a cam arrangement or can be a simple solenoid.
- the present invention relates to amist generator. More particularly this invention concerns a socalled coldmist generatingsystem usable for humidifying the air.
- Another object is the provision of a method of making an extremely finely divided and dense mist.
- a further object is the provision of a mist generator which Operates efficiently and silently.
- a generally closed vessel which is filled to a predetermined level with a liquid and is formed above this level'with a tdeflectable wall and with an aperture.
- a transducer is provided in the vessel below the level of the liquid'and is focused generally at the level of the liquid.
- Motor means ispro vided to periodically deflect the wall ofthe vessel so that the'mist formed by the ultrasonictransducer is expelled through the aperture in the side wall of the vessel.
- the dcilectable wall of the vessel is an elastic membrane constituting the top of the vessel andis vertically displaceable by means of an electrically operated motor.
- the operating motor comprises a lever connected at one end to the deflectable wall of the vessel. Another end pivoted at a fixed point. and a rotatable eccentric cant engageable with this arm so as to pivot it back and forth thereby dcflecting the wall of the vessel.
- Control means is provided which cycles the pump and energizesthe piezoelectric transducer with ultrasonic-frequency alternat ing-current electricity for a time period sufficient to generate in the vessel a body of mist having a volume corresponding to the displacement volume of the pump on one cycle.
- the transducer is energized to form a body of mist having a volume corresponding to the displacement volume of the pump on one cycle.
- the transducer is energized to form a body of mist. then the pump is operated to expel this body of mist from the vessel,
- the arrangement is cycled continuously. or is controlled by a humidistat or the like so as to humidify the surrounding air to a predetermined extent.
- the arrangement for maintaining the vessel filled to a predetermined level comprises an inverted-bottle feeder having a reservoir provided with a nozzle which is the soleopening between the interior and exterior of the-reservoir.
- This nozzle projects down into an upwardly open feed vessel so that when the feed vessel is filled up to the level of the nozzle. fluid flow out of the nozzle is arrestd.
- This feed vessel is arranged next to the mist-generating vessel and is connected thereto via a conduit so that the levels in the two vessels are the same.
- FIG. 1 An inverted bottle 1 supported on apair of fixed rails 32 is arranged upside down with its neck 33 received in an upwardly open filling vessel 5.
- a valve body 2 in this neck 33 is urged downwardly by against the bottom of this vessel 5 tolift the valve body 2 fromthe seat 4 thereby allowing liquid in thebottle 1 to flow out into the vessel 5, filling itto a level L.
- other vessel 7 is fixed adjacent the filling vessel 5 and is connected thereto by a conduit or tube 6 which is located entirely beneath the level L' so that the vessel 7 is alsofilled to a level L identical to the level L.
- this bottle I together with the vessel 5 and conduit 6 form an inverted-bottle feeder 34 which functions to maintain the liquid level'in the vessel 7 at a constant level L.
- the vessel 7 is formed with a lateral aperture 10a connected to an upwardly directed nozzle 10. This aperture 10a is above the level L.
- a piezoelectric transducer 8 which is focused at a point p lying at the level L. Encrgization of this transducer with alternating-current voltage at an ultrasonic frequency from a source S serves to form mist 8 in the vessel 7 above the level L.
- the vessel 7 is rigid except for its upper wall I] which-is formed by a deflectable elastic membrane connected to a rod 12 vertically reciprocal in a fixed yoke I3.
- a spring I4 is braced at its lower end against the yoke 13 and at its upper end against a washer 12a fitted to the rod I2 so as to urge this rod upwardly, also pulling the wall I] up into the solid-line position of FIG. I.
- a drive arrangement 35 comprises a motor 19 provided with a shaft 18 on which is carried a noncircular cam 17.
- a lever 15 has one end resting on the upper end of the rod I2 and the other end pivoted at 16 on the motor. This lever I5 rests against the cam 17 so that on rotation of this cam I7 it is deflected between the upper solid-line position of FIG. I and the lower dotdash position of FIG. 1, thereby also vertically deflecting the wall 11.
- Control means 9 is provided to connect the source S to the transducer 8 for a period of time sufficient to generate a predetermined volume of mist 8. Meanwhile the cam 17 is rotated so that each time this predetermined quantity of mist is generated the wall 11 is deflected once to drive it out of the nozzle 10. Thus each revolution of the cam 17 in direction S about its axis 18 takes slightly more time than the time necessary to generate the requisite quantity of mist. Thus the mist is generated in a volume at least equal to the displacement of the deflectible wall.
- Such an arrangement is usually provided at its controller 9 with a humidistat or the like which cycles it periodically until the humidity in the room is at the desired level. It is noted that when the device runs out of liquid in the bottle I there is no danger of overheating or damage, as the liquid level will drop from level L thereby making the transducer almost totally ineffective so that the device will merely cease to function.
- FIG. 2 The arrangement in FIG. 2 is similar to that shown in FIG. I with identical reference numerals used for identical structure.
- the shaft 18 is fitted with a second cam 20 in addition to the cam 17.
- This second cam 20 is engageable with the actuating arm 22 of a fixed switch 2] that is connected to the source S and replaces the controller 9.
- the cam 20 serves to close the switch 21 thereby connecting the source S tothe transducer 8 immediately after the cam I7 has allowed the lever 15 to rise to its uppermost position.
- This switch remains closed for approximately 200 of rotation of the shaft 18, thereby allowing the transducer to generate a predetermined quantity of mist in the vessel 7.
- the operating arm 22 falls off the cam 20, disconnecting the source S and the transducer 8 and shortly thereafter the cam 17 depresses the lever 15 and pumps the newly formed mist out the nozzle 10.
- Such an arrangement is intended for continuous operation.
- the device of FIG. 3 again uses the reference numerals of FIGS. 1 and 2 for identical structure.
- the upper wall II is connected to a plate 24 carried by a simple fast-acting solenoid or vibrator 23 operated by the controller 9.
- a partition wall 27 provided with a hole 28 covered by a flap-type check valve 29 is provided across the vessel 7' above the mist B and the level L so as to define an upper compartment 26 and a lower compartment 25.
- the rigid wall of the vessel 7' is formed at the compartment 26 with a hole 30 again provided with a flap-type check valve 3! allowing entrance of air only into the chamber 26.
- the motor 23 rapidly presses down the membrane II. causing air in the chamber 26 to be driven past the check valve 29 into the chamber 25, thereby expelling a predetermincdquantity of mist B from the nozzle I0.
- the valve 31 is closed.
- valve 29 closes to prevent the mist B from being sucked back into the nozzle I0, while at the same time the valve 31 opens to allow a new mass of air to be drawn into the upper chamber 26.
- the partition 27 as well as the check valves 29 and 3I prevent the apparatus from merely expelling a quantity of mist and then sucking it back in again as the membrane is drawn back to its starting position.
- the relatively slowly acting piston rod 12 does not have this effect as the expulsion through the nozzle 10 and later aspiration of air back into the nozzle 10 takes place slowly enough to allow proper dissemination of the mist B.
- a mist generator comprising:
- said vessel being formed above said level with a throughgoing outwardly open aperture and having at least one deflectible wall;
- means including a transducer below said level in said vessel for generating and focusing ultrasonic vibration on a location in said liquid at substantially said level to generate a homogeneous body of mist above said level.
- said aperture communicating with said vessel by a passage opening within said body of mist;
- control means connected to said transducer and to said means for deflecting for operating said transducer for a predetermined length of time and thereafter deflecting said wall.
- control means includes a motor and at least one cam mounted on and rotatable by said motor.
- the generator defined in claim I further comprising a partition across said vessel between said level and said deflectable wall.
- said vessel being provided with a first check valve permitting air flow into the region between said partition and said wall and a second check valve permitting air flow from said region through said partition to the region between said partition and said level.
