Description

200808452 IX. Description of the Invention: [Technical Field] The present invention relates to an atomizing device, and more particularly to a power supply benefit for an atomizing device. The atomizing device comprises first and second electrodes, one of which is a spray electrode and the other is a reference or discharge electrode. The power supply applies a voltage between the two electrodes, as described below, such that the liquid within the spray electrode is atomized. [Prior Art: j Background of the Invention 10 An electrostatic spray device uses an electric field to be applied between a spray electrode (a liquid is fed into the electrode and exposed to a maximum amount to an electric field) and a reference electrode somewhere in the vicinity A potential difference decomposes the night body. This type of spray is well known and has been used by Sir Geoffrey Taylor in 1964.

Proceedings of the Royal Society is described on pages 383-397. 15 This technology is often referred to as electrospray technology. The substance to be sprayed or atomized is usually a liquid which is dispersed as a spray of substantially monodisperse particles. Electrospray is exemplified in European Patent No. 1,399, 265, which is incorporated herein by reference. The atomization of the liquid is achieved by the electronic device generating a high surface charge on a liquid. - a potential difference is applied to a spray 20 electrode (the liquid is dispersed therefrom) and a discharge or reference electrode (each electrode is placed in a - dielectric) 'active ingredients carried in the liquid, the composition The dispersion of (active ingredient) is achieved. An efficient spray can be produced, consisting of appropriately sized droplets (dr〇plet) carried by the air, and does not penetrate quickly into the ground under the influence of gravity. For a given composition, the diameter of the droplets such as 200808452 can be controlled (at least to some extent) by experimentally varying the applied voltage and liquid flow rate. Depending on the local electric field, the droplets are initially separated from the spray electrode. Subsequent discharge of the discharge electrode near the dielectric prevents the droplets from being drawn back into the device. If the voltage on the electrodes is balanced, the injection of the 5 liquid composition is immediately stopped. For the purpose of mass production of electrospray devices, it is desirable to keep the applied voltage at a known value and to re-form individual liquid compositions such that they possess certain physical properties, such as specific application. The proper conductivity and viscosity of the voltage and the desired flow rate. 10 When a liquid composition is so formulated but the output voltage is subject to slack manufacturing tolerances, the spray condition may not be optimal, increasing the chance that droplets will deposit on the discharge electrode, the dielectric, and, if present, any of the outer casings. During liquid composition, spray droplet deposition on the sprayhead also occurs as a result of the relaxed formulation limits, so that its physical properties do not apply to 15 preselected output voltages across the showerhead. , or may occur due to degradation of the liquid composition (eg, due to chronic oxidation), or may occur as a result of degradation of the spray electrode or a less stringent combination of spray heads. The result of these changes is that the electric field and/or ionic breeze carried by the sprayed droplets does not actually transport them away from the nozzle. The operation of the head under high humidity, especially in condensed humidity (e.g., in a home bathroom) may result in an electrical connection between the electrodes formed by the liquid on the showerhead such that the surface resistance of the showerhead is reduced. This may result in a reduction in the voltage at the spray site until the air is no longer ionized and depending on the local electric field, the dots are no longer transported away from the spray electrode. If the applied voltage required for the atomized liquid composition is lower than the voltage required for the ionized air, the substance from the electrospray site is continuously atomized without being discharged and blown on the ion breeze. go. 5 Apparatus for limiting or preventing the effects of load changes on the spray head is known in the art. U.S. Patent No. 6,880,554 B1 discloses an air filter wherein the spray path created by the spray device is defined in part by a flow of air drawn by a user's breath, which allows passage across the electrospray site. And away from the discharge electrode. No. 6,656,253 10 B2 teaches an apparatus in which a charged spray is introduced into a mechanically obtained gas stream which forces the spray away from the dispensing electrode to a collection reservoir (collection reservoir) ). Droplet deposition on or near the electrodes in the electrospray device disclosed in U.S. Patent No. 6,397,838 is believed to be controlled by the placement and geometry of the nozzle, but the device exhibits performance due to local electric field variations at the spray site. change. The effect of the liquid disclosed in U.S. Patent No. 6,729,552 B1 being condensed into the counter electrode of the apparatus is controlled by the optional heat application and/or adsorbent material directly to the counter electrode. The electrode itself can be heated to promote evaporation of material that has reached or is condensed on the electrode. Alternatively, a high surface area adsorbent material can be placed in contact with the electrode or elsewhere in the outer casing to prevent the inefficient spraying of the body composition from the device. None of the above techniques are satisfactory because they require additional electrical, mechanical or user-assisted thorns by the sprays emitted by the electrospray device. Such mechanical, user or geometrical assistance includes the introduction of additional electronics or housing components and their associated manufacturing and power costs, user added or coarse or unsuitable appearance. Alternatively, the adsorbent material can act as a reservoir for the liquid composition, potentially exposing the user to a non-known amount of the active ingredient of the liquid composition, some of which may be detrimental or dangerous to human health. US 6,274,202 discloses a method for controlling the operation of a powder spray coating apparatus comprising the purpose of overcoming spray overcharge and Peel e in a powder coating when the spray apparatus approaches a 10 When the workpiece is used, the discharge current and discharge voltage of the electrostatic charging device are automatically reduced. The device disclosed in US 6,274,202 comprises an oscillator for driving a transformer whose secondary winding is connected to an EHT multiplier. An indirect measurement of the output power from the eht multiplier is obtained by measuring the current flowing through the vibrator, and the output voltage of the oscillator is adjusted from -15 using a positive feedback technique to When the spray device approaches the workpiece, an appropriate _ discharge current and discharge voltage are set. However, a method of indirectly measuring the output power is such that the device cannot distinguish between the power consumption in the desired load (i.e., the actual output power) and the power consumption lost in the transformer and the EHT multiplier. Moreover, the device does not have a way to monitor the actual output voltage and 20 electrode current, and thus these feedback controls cannot be used to overcome any changes that occur during use or due to manufacturing tolerances. As can be seen, there is a need for an electrospray device that automatically responds to inefficient spray conditions caused by slack manufacturing tolerances, extreme environmental conditions, condensation of steam (eg, water vapor) on the spray head, Sprayed micro 8 200808452 drops or, he liquid n on the spray head or spray electrode or discharge electrode sink [invention] According to the invention - level, an atomization device is provided, including one for the younger brother - And a voltage supply between the second electrode and the second electrode, the power supply comprising - (four) circuit, the secret (4) the applied voltage causes the basin to have - the desired value, and - the monitoring circuit is adapted to monitor the flow through the first And the current of the second electrode and according to the -like characteristic, the expected value is changed according to the monitored current.

The monitoring circuit is further adapted to monitor the applied voltage and is adapted to provide an output signal indicative of the monitored voltage to the control circuit 5 such that it can control the applied voltage to have a desired value. This provides the The closed-loop control of the applied voltage. Although it is possible to use an open loop control technique, it is to be understood that this is less desirable because it is more difficult to stabilize the applied voltage to a desired value. In the embodiment A voltage is measured at the junction of the two resistors forming a voltage divider connected between the first and second H) electrodes, the monitoring circuit monitoring the applied voltage. In another embodiment, the monitoring circuit monitors the applied voltage by measuring the voltage across the diode in series with the bias resistor between the first and second electrodes.

In a preferred embodiment, the power supply includes a vibrator for generating a parent stream and an inverter circuit coupled to the oscillator for generating a voltage applied from the alternating current. The inverter circuit can include a charge pump and rectifier circuit, such as a Kirklaw_Walton generator. In one embodiment, the power supply controls the applied voltage by controlling the magnitude, frequency or duty cycle of the oscillation of the oscillator. In another embodiment, by causing the oscillator to generate an AC burst at a predetermined frequency, the power supply controls the applied voltage, and the duration and/or duty cycle of the bursts determines the The value of the applied voltage. Typically the power supply is further adapted to monitor the applied voltage so that it can control the applied voltage in accordance with the predetermined characteristic.

[Embodiment] 10 Fig. 1 is an illustration of an electrospray device suitable for use in the present invention, as described in European Patent No. 1,399,265. It comprises a spray electrode 1 placed close to the exit surface 5 of the device, and another reference and discharge electrode 3 in proximity, also placed close to the exit surface 5 of the device. When assembled in an open geometry, the two electrodes are generally protected from interference by the user by masking the respective recesses 2, 15 • 4 inside the exit surface 5. The exit surface 5 is formed of a dielectric material that is selected such that it discharges at a low velocity so that any charge deposited via ions or charged particles does not immediately move or bleed. This ensures that when these dielectric recesses 2, 4 are trapped of the electrodes, a slight charge of the same polarity as the electrodes is retained. This greatly changes the local 20 electric field shape and most effectively ensures that further deposition is prevented, without the need for additional electrodes. Yet another advantage is that the device is polarity independent. In other words, the spray electrode 1 can operate at any voltage (positive or negative) and the discharge electrode 3 can operate at any other voltage - if in the first case the potential difference is only sufficient to cause a spray. The range of potential differences that can be operated depends on the following: the distance between two 18 200808452 electrodes, their relative position relative to the exit surface, the shape or contour of the spray surface, and the size of the recess itself. The potential difference can be up to 3〇kV or more from i_2kV, and the relative polarity can be positive or negative. The hemisphere electrode 1 in this example contains a 30 gauge metal hair '5 thin tube, and The discharge electrode 3 comprises a sharp stainless steel needle having a diameter of 〇.6 mm. The two longitudinal axes of the cylindrical recesses 2 and 4 are perpendicular to the spray outlet surface 5, which is made of a dielectric material. . In this example, the material is a crucible and the jet exit surface 5 is flat. However, other materials and a curved surface may be used if sufficient charge remains on the spray exit surface 5 to deflect the spray and charge carriers away from the device and electrode. Electrical connections are made via the wrapped metal tubes 6 and 7, which are electrically made with the f poles 1 and 3 and the 1 source supply (4), respectively, which are supplied with power from the battery 11. The atomized liquid is retained in a stock solution 8 and air is fed into the reservoir 8 via a small air inlet opening 9 to replace the chemicalized night body. Conveniently, one or more radio frequency identification (RFID) tags can be placed on or connected to the reservoir 8. In the case where the power supply is supplied by the power supply, for example, by inserting a battery or by an electronic timer, the liquid from the reservoir (10) is in a very fine form from the spray electrode. It is emitted to cause rapid evaporation according to its steam dust force and the surrounding conditions in the vicinity of the teaching. This type of electrostatic spray device can be adapted to dispense a formulation in an accidental or continuous manner. Fig. 2 is not shown for an alternative reservoir and capillary 19 200808452 unit of the present invention, wherein the discharge electrode 3 is not an element of the capillary unit. In this example, the reservoir 8 is provided in the form of a flexible container having two resilient walls sealed by a seal 21, a spray electrode 1 being in flow communication with the reservoir 8. The spray electrode crucible is located on the seal 21. 5 The conduit 25 in this example comprises a 27 gauge capillary (e.g., a stainless steel capillary)' unless simply fabricated from any semiconductor material including, for example, a modified plastic. The elastic reservoir in this example comprises a wall formed from a film of a polypropylene/aluminum/PET laminate, although there are many other possible materials that can be used for themselves or in many combinations with Other phase stacking. 10 The resilient liquid and conduit system is physically protected by a housing 22 which may be an individual entity that accepts and places the flexible reservoir and conduit system during manufacture or may be integrally included. Suitably, one or more 1^1 tags may be embedded or disposed on the housing 22. An RFID tag (communicating with or embedded in the reservoir 8 or protective structure 22) 15 can be active, preferably semi-passive or, more preferably, passive. The RFID tag can include a globally unique identifier (Gum) or a non-volatile electrically erasable programmable read only memory (EEPR〇M) or a combination thereof. A printing member 23 (e.g., a soft polymer compound) can be repeatedly removed and replaced to further prevent liquid from flowing out of the reservoir. In this example 20, a cover 24 provides a means for supporting the seal member 23 and maintaining its seal position when applied to the end of the spray electrode 1. The outer casing may further provide a position and support for connection to the conduit 25 or reservoir 8, such as applying a motion (e.g., vibration) or a high pressure connection 25, which causes electrical contact with the spray electrode 1. 20 200808452 When a high pressure is applied across the spray electrode 1 and the discharge electrode 3, the liquid composition exposed at the top of the spray electrode 1 encounters a strong electric field against the surface tension of the liquid, causing it to decompose the wire Electric droplets. Similarly, the electric field also causes ions of opposite polarity to the spray on the discharge electrode 3 to pass through each of the two opposite charges in the front of the spray outlet surface 5. The combination of solids, the viscous force of the droplets in the air becomes the main force on it, etc.' Under the gentle breeze created by the initial rapid motion of the initial charged entity, it is pushed away from the device. The spray surface illustrated in Figure 3 shows a possible spray surface. 10 15 20 "The power source 11 is coupled to the spray electrode and the test electrode 3 via a drive circuit, and the voltage generated from the power supply 1 () has a droplet size, a residual droplet charge, and A liquid composition of a desired characteristic of flow rate. A spray. The potential difference applied between the spray electrode and the discharge electrode depends on the geometry (and size) of the showerhead and may range from 1 to 4] Any range of 乂. For the example provided in Figure 1, where the distance between the tips of the electrodes is 8 mm, the magnitude of this voltage is, for example, a range of 3_6 kv, preferably 4.5-5_5kV, ideally 4.9kV, when the head load is equal to 6GQ. In many cases, if the aforementioned potential difference is maintained, the polarity on each electrode is not important. In addition, although it is usually convenient to one of the electrodes Or another electrical ground, but this is not essential. Figure 4 shows a prior art power supply that produces the high voltage required between the electrodes. It consists of four stages: a low voltage direct current (DC) power supply. Supply state 40 (usually one or more Voltatable batteries, which can be combined to form a battery); a unidirectional oscillator 41, causing alternating current (AC) bursts; an electromagnetic or piezoelectric transformer 21 200808452 to deliver low pressure into a seam; and - a charge of rectification (10) or Kirk The Lauf-Walton generator gradually rises to the seam exchange and even rectifies it back to DC. In this line, there may also be -_ network 44, red control the round and when appropriate (four) recorded The voltage across the negative 5 is expected to be the desired value. It may also include - a "new resistor 46" that spans the turn, allowing charge to flow from the Kroklaw Voltton generator or "by comparison, Because the external load (the nozzle) cannot be naturally fast enough • Do so because the resistance of the nozzle is not proportional to the applied voltage. 妓- species is generated according to _ control - Gaolang is more conventional and commercial w The device is applied. However, other sources of high voltage (e.g., a Van de Graff generator) can easily replace the three stages and maintain a functional embodiment of the present invention. The situation of the big material, the fine The source supply has been designed to generate a stable voltage. This means that the output of the power supply is independent of the load W f(R), where v is the applied electricity • Μ 'R is at any given time Point on the nozzle resistor, and 岐 a constant of the circuit.) This is by far the most common type of high voltage circuit. According to the - stable voltage drive circuit 'if the nozzle's resistance is reduced (eg due to the - humid environment τ Water vapor is cold (iv)_), and the current (4) (dmw) of the current will increase rapidly. The rapid increase of this current may be a problem if the device is operated by the battery because it greatly reduces the service life of the device. 'If the resistance of the showerhead increases (for example due to a collision of droplets on the discharge electrode), the current is reduced, reducing the discharge efficiency of the showerhead, which typically results in further deposition. 22 200808452 An alternative approach is to create a steady current system instead, where a mai test voltage is defined according to a typical nozzle resistance and then the current is held at this level. In this case, the voltage is a function of the load or V = f (R > ^R, where /3 is a constant proportional to the resistance of the nozzle, and the current is the current set by the circuit. Slightly different: if the nozzle resistance is reduced (for example due to condensation humidity), the voltage is reduced, if it is lowered below the operating voltage of the nozzle. Similarly, if the nozzle's resistance is increased (For example, due to the collision of droplets on the discharge electrode), the voltage is increased to help rid the discharge electrode of the material to be collided. However, in reality, due to the nonlinearity of the nozzle resistance The reason is that a steady current circuit usually causes a problem. If the voltage is lowered, it usually cuts off the discharge current before cutting off the electrospray. This causes some droplets to collide on the discharge electrode' and although this may cause an increase in voltage , but in fact, 15 never maintains its initial level, and thus the program is amplified until the reservoir is empty. We have empirically found that some combinations of these extremes are preferred. For example, the Solo electrospray assembly 20 manufactured by Aerstream Technology Limited, Pipe House, Lupton R0ad, Wallingford, 0X10 9BT uses a "tap-type feedback, system to maintain a voltage across the nozzle that is nearly stable, but at A slight increase at low load and a slight decrease at high load. The relationship between voltage and load v = f(R) is complex and is shown together with the contact current and contact voltage relationship in Figure 5. This response It is obtained from the fact that this feedback is obtained earlier in the charge pump ladder (and is slightly "removed" from the actual output from 23 200808452, and each stage of the charge pump ladder is not 100% efficient Excessive loss at the high voltage end. Although satisfactory for electrospray, this circuit causes more than the required current, resulting in reduced battery life. 5 Figure 6a shows a power supply for an atomizing device in accordance with the present invention. The first embodiment, as shown, is similar in many respects to the prior art power supply shown in Fig. 4. However, instead of the simple feedback arrangement shown in Fig. 4, There is a more complex feedback network 60. As shown, only passive resistors are used in the feedback network 60. In this circuit, the selection of resistors can produce a voltage_load response function (V= The f(R))' range ranges from a stable voltage response to any mix of current and voltage control. The bleeder resistor 46 no longer straddles the load 45 directly, instead of straddle the load 45 in series with the bond resistor 62 (i.e., between the spray and discharge 15 electrodes). Thus, the voltage at the junction of the bleeder resistor 46 and the junction resistor 62 represents the voltage across the load 45. A choke resistor 61 is provided in series with the load 45 such that all current through the nozzle mist and discharge electrodes (and thus the load 45) also passes through the choke resistor 61. Preferably, the current-resistance resistor has a value of 1 in the range of 20, and more preferably, in the range of 500 Ω to 1 〇〇Μ β. As shown, one end of the choke resistor 61 is connected to a ground reference point of the power supply, and thus the voltage at the junction of the choke resistor and the junction resistor 62 indicates that the flow occurs. Two electrodes and the current of the load 45. Thus, the signal across the feedback resistor 63 is a sum of the signals representing the voltage between the spray and the signal electrodes of the reference 24 200808452 indicating the current flowing through the electrodes. Oscillator 41 produces alternating bursts at a predetermined frequency ^^, early, and duty cycle. Although k the voltage across the feedback resistor 63 is reduced to a critical value (typically 5 疋 1 volt) under the defensive, the vibration is crying when the private profit breaks the start' and when the voltage increases above this When the value is reached, the disc is stopped. Fm攸 and the output of the oscillator 41 corresponds to the voltage at the feedback packet resistance of 63, such that if the feedback voltage falls below a critical value, the AC burst from the vibrator 41 appears more frequently, and conversely, If the voltage on the feedback resistor 63 increases, the AC burst from the oscillator 10 does not occur frequently. When the f-flow through the electrodes is very low (i.e., the load impedance is very high), the voltage across the anti-flow resistor 61 is very small and negligible. Thus the signal across the feedback resistor 63 represents the voltage across only the load, and this voltage is controlled by the start and stop of the oscillator when appropriate to maintain the signal across the feedback resistor at 1 volt. However, if the current increases (e.g., due to condensation on the showerhead), the voltage that is reduced across the choke resistor 61 will increase. The oscillator 41 generates bursts as appropriate to maintain the signal across the feedback resistor 63 as close as possible to 1 volt. Since this signal now contains a 20 element representing the current flowing through the electrodes and the voltage across the electrodes, this has the effect of reducing the voltage across the load 45 and thus the current flows to compensate. In other words, a small burst of oscillations is required to maintain the signal across the feedback resistor 63 at 1 volt and the voltage across the electrodes is reduced. In this way, the efficiency of the operation can be improved and battery life can be protected by taking a new operating point on a lower current and voltage. This results in lower execution costs for those who use 25 200808452. Fig. 6b shows a characteristic curve having various values of the bleeder resistor 46, the junction resistor 62, the choke resistor 61, and the feedback resistor 63 (the voltage across the electrodes is applied to the nozzle). It should be noted that the curve displayed when the connection resistor 5 62 has a value of 0β is only provided as a comparative example, which is not practical for general applications, because if the connection resistor 62 has a value of 〇Ω, then It is not possible to measure the voltage across the load 45 and the feedback network 60 as shown. When the bleeder resistor 46 has a value of 4 GQ, the splicing resistor 62 has a value of 10 Ω, the damper resistor η has a value of ι μΩ, and the feedback resistor 63 has a value of 5 ΜΩ, the output is similar to The output of the tapped feedback of the aforementioned §1〇 device. The specific values of the anti-flow and connection resistors 61 and 62 are selected based on (between other factors) board layout, component quality and loss, electrode geometry and 15 materials, materials to be sprayed, and the housing. . The resistance value is chosen to minimize the manufacturing tolerance. Typically, the feedback resistor 63 is a potentiometer that is adjusted to achieve adequate circuit performance. Figure 7a shows a second embodiment of the power supply of the present invention. This embodiment is very similar in structure to the first embodiment, with the only difference 20 being that a junction resistor 62 is replaced by a semiconductor body 71 to create a different feedback network 70. The signal on the feedback resistor 63 is now the voltage across the anti-flow resistor 61 (depending on the current flowing through the spray and reference electrodes and the load * $) and the forward voltage of the diode 71 (corrected by the resistor) The sum of the bias voltages). Thus, across 26 200808452, the (4) of the feedback "63" changes with the voltage variation across the spray and reference electrodes and the current flow through the electrodes and loads. We have found such nonlinear characteristics. Especially suitable for electrospray atomization devices. ' 5 10 15 20 In particular, a way is provided to select the stable voltage and the steady current ideal voltage · domain shouting _ optimal characteristics. In this case, when the load When the resistance of 45 is lower than some nominal reference load resistance, the voltage across the electrode is maintained at a stable value, and the choice of the nominal reference load resistance depends on the geometry of the nozzle and the desired optimal voltage (4). Thus, if, for example, the showerhead becomes more conductive (eg, under condensing humidity), (iv) the voltage does not decrease, and (iv) maintains a proper (iv) fog discharge. In the illustrated embodiment, the appropriate value of the reference load resistor It may be $2 to 2, ie, Cong. However, if the load resistor 45 is increased above this nominal reference load value, the voltage rises as the domain resistance increases. Thus, for example, if a droplet is temporarily deposited in the discharge On the electrode, increasing the resistance of the nozzle, the circuit responds by adding the voltage, thereby increasing the chance that the discharge electrode will electrostatically remove the material deposited thereon. In an extreme use case, where the liquid has been deposited On the reference electrode 3, or wherein the reference electrode has degraded over time, resulting in a decrease in load current (i.e., the flow of the flow-axis spray electrode and the reference electrodes 1 and 3, the load impedance of the showerhead is increased. The flow resistor is also called ^the voltage on the test electrode 3) is also reduced. This voltage drop causes the voltage drop on the feedback resistor to cry 63. The response from the _ oscillator is motivated to generate more frequent; The voltage across the electrodes responds to the load resistance 27 200808452 across the surface of the pole to increase the surface of the discharge electrode and clear the supply of the discharge ions, so that the discharge (four) time has passed Late pure or coated with material.

On the 10 15 4 side, the junction diode 71 is -BAWS, and the resistor 63 has a value of 5 touches. This reference voltage is 4.8 kV at the reference load of 6G. The ratio of the feedback characteristic to the reference electrode is determined by the value of the diameter of the choke resistor (10). It is clear that although the higher value allows the voltage to rise faster and the IV has a value of I, the circuit maintains a relatively stable voltage. For comparison purposes, the dashed line shows the equivalent characteristics of the tapped feedback that has been mentioned with respect to the Solo device. As can be seen, these characteristics are very similar at approximately 6GQ of load impedance.

Fig. 8 shows a third embodiment. Again, this embodiment is very similar to the second and second embodiments. However, in this case, the feedback signal for controlling the oscillator 41 is generated in the digital domain. In particular, a analog to digital converter 81 is used to monitor the output voltage from the charge pump and rectifier 43 and the load current flowing through the spray and reference electrodes and load 45 via bleeder resistor 46. Each of these is converted to a digital signal that is fed to a digital computer 82. The digital computer 82 then processes the signals in accordance with a pre- > beneficiary method to produce a digital feedback signal that is provided to the digital to analog converter 83. This produces an analogy from the digital feedback signal to 200808452 and provides the analog signal to oscillator 41 to control its start and stop to control the output voltage in a desired manner. The computer 82 can be used to generate any desired feedback response, assuming that the frequency response of the computer 82 is fast enough, e.g., above 1 kHz, typically the 炀 shape. Additionally, one or more digital wafers can be used in place of the digital computer. Several solutions, such as this solution, have the advantage that different nozzles can be detected by the feedback system and the feedback response can be adjusted accordingly to provide a more flexible device. The use of a digital computer 82 makes it very simple and even further enhances the invention. First, the reservoir 8 can have a radio frequency identification (RFID) tag disposed thereon or embedded therein. The RFID tag transmits a signal identifying the liquid composition contained in the reservoir 8. The signal can be detected by an RFH) interrogator (not shown), and an output signal from the interrogator can be provided to the digital computer 82, which can then set which liquid needs to be The atomizing device is sprayed. The digital computer 82 can then adjust the digital feedback signal accordingly such that the voltage across the electrodes is set to an optimum value for the liquid to be sprayed and the current flowing through the dedicated electrode. A second improvement involves returning to the surroundings of the 20 in which the atomizing device is operating. To do so, the sensor can be connected to the digital computer 82' to detect one or more surrounding conditions including ambient temperature, pressure and humidity. The digital computer can respond to the wheeling signal from the sensor connected thereto to adjust the digital feedback signal (depending on the type of sensor being connected) according to the ambient pressure, temperature and humidity, thereby The ambient voltages 29 200808452 and the current flowing through the electrodes cause the voltage across the electrodes to be set to an optimum value. Of course, the digital computer can receive the wheel man from the surrounding situation sensor and an RFID query H, and adjust the digital feedback signal according to the predetermined data matrix or according to a suitable algorithm, so as to The situation and the particular nucleus being sprayed, such that a suitable voltage is applied across the electrodes. The digital computer can also control the duty cycle of the electrospray dispersion 10 of the liquid composition based on such ambient conditions and/or the liquid composition identified by the RF detector. Fig. 9 shows a fourth embodiment. It is similar to the first and second embodiments. However, the feedback network 91 monitors the voltage across the charge pump and a node within the rectifier 43 via a trickle resistor (tHekle reSiStr) 92. The trickle resistor 92 is connected within the charge pump and rectifier 43 to the level 15 of the charge pump so that the voltage it monitors is a small fraction of the voltage between the spray and the reference electrode. It therefore provides a selectable position from which the voltage across the electrodes can be monitored, albeit in an indirect measurement. The feedback network 91, the trickle resistor 92, and the bleeder resistor 20, can be provided to monitor the voltage across the scale and the voltage within the charge pump. Although the addition of (four) current resistance H92 increases the component and f is a more complex feedback network, it is useful in situations where the load 455 picks up (d) the flow exceeds the charge spring. In this case, there is a simple relationship between the voltage at any of the levels in the charge I and the voltage across the electrodes. Therefore, useful information can be obtained by measuring the deviation from the desired scalar relationship. The drop "child resistance benefit 92 can be provided instead of the Maomei resistor. If the value of the flow resistor is such that the circuit can be discharged, the charge spring can be discharged at a rapid rate 5 times. In this case, the resistor II with a lower voltage rating can be used, which is generally cheaper and can have a more precise manufacturing tolerance.纟In case of precise _round power _, the (four) discharge resistor 46 is used alone. In the case where it is desired to use a high tolerance, low cost component, 10 the trickle resistor 92 is used. In a variation of this fourth embodiment, a plurality of trickle resistors are provided, each connected to a different stage of the electrical view. This arrangement can be used when low value resistors are used and the losses in the charge pump can be interpolated or extrapolated, and it is thus inferred that the exact value of the turn-off voltage is desired. This arrangement can also be used with the bleeder resistor 46. • The present invention can accommodate a wide range of formulation, establish different levels of space charge and thereby provide different load characteristics. By making a rise in the load current (which may be independent of the input (four) voltage), the _ voltage rises and the output voltage is reduced to compensate. 2〇 A 1st diagram shows a pattern with a load response of Figure 7b superimposed on a different/night body loaded load curve sprayed through the same nozzle. The two liquids that can be seen are represented in different ways, with different loads being applied to the drive circuit of the spray head. Formulation 1 (higher line along the drawing) indicates that the liquid is only sprayed at a higher voltage. It can be seen from the figure that the "tap-type feedback" load response curve does not intersect the load curve of configuration 1, but only tangentially meets the curve of formulation 2. The actual result is a combination of Formulation 1, and the nozzle (driven by a "tap-type feedback" circuit, set to 4.8 kV at 6GO) does not form a stable output. In order to obtain this spray formulation, the circuit needs to be driven at a higher voltage, such as 5.2 kV at 6 GQ. It is very inconvenient to set up the circuit differently for different configurations. In a commercial unit, the need to adapt a circuit to a formulation is generally not an economical practice, and the use of such circuitry actually limits the range of formulations available for the product. However, a power supply similar to that illustrated in Figure 7a (whose load response curve is superimposed in Figure 10) allows for a wider range of spray-to-spray configurations to be used without having to adjust the drive circuit. This reason is illustrated in Figure 10 by the following facts: marked as "bleeder resistance = 4 Ό Ω, dc resistance = 44 Μ Ω, _ 15 • connected diode = BAV23S, feedback resistance = 5MQ (4.8kV @ 6GQ)" The curve intersects all three formulated load curves. Figure 11 shows the same load response curve for both a "tap-type feedback" circuit and the circuit illustrated in Figure 7a (with a diode in the feedback network). However, for the same formulation sprayed through different nozzles, there are two load curves that are superimposed. Although the two nozzles are nominally the same, in other words they all conform to the same manufacturing specifications, they produce slightly different load profiles. This is due to small differences in electrode position and its surface processing. Such variations in the load curve with high standard manufacturing tolerances are typical. According to the looser tolerance, the difference between 32 200808452 in the load curve is more extreme. The circuit described in the present invention and illustrated in Figure 7a provides a good cross-H plane through the negative _ line of the head. This "tap-type feedback" circuit must be simplified, which is inconvenient. . The patterns of Figures 00 and U clearly demonstrate the advantages of controlling the load response curve that is desired to be used with an electrospray. The circuit of Figure 7a can produce a stable time for a wide range of formulations and sprays, and from (four) have (four) Cheng # application. In addition, because it can handle more extreme formulations and nozzles, it also responds better when the nozzle is exposed to extreme conditions. This further adds to the application area of a product using this circuit, which has obvious commercial benefits. Figure 12 shows a portion of an appropriate circuit for use with the previously described embodiments. In particular, Fig. 12 shows the appropriate circuit of the transformer 42 and the oscillators 41-15 and a Kirktor-Wortz generator (shown only one stage) used as the charge pump and rectifier circuit 43. In this case, the circuit is powered by a 6V DC source (e.g., a 6¥ battery pack) connected between the electrical ground and the ground. The oscillator is a tuned main push-pull Royer transistor type 20' comprising a pair of matched transistors Q1 and Q2. Suitable transistors Q1 and Q2 are ZDT1048A manufactured by Zetex PLC, Zetex Technology Park, Chadderton, Oldham, 0L9 9LL, UK. The operation of this oscillator is controlled by the MAX761 manufactured by Maxim Integrated Products Inc., 120 San Gabriel Drive, Sunnyvale, CA 94086 USA, which receives the output from the feedback network on the feedback pins of 33 200808452. The ΜΑΧ761 疋 is always a DC-DC converter control, although in general, any pulse width modulator or burst frequency modulator can be used. The transformer "TFR" has three main coils and one sub-coil having a number of turns higher than five turns of the main lines. A suitable transformer is by Cooper Bussmann, Cooper Electronic Technologies, 1225 Broken

Sociend Pkwy NW, Suite F, Boca Raton, FL 33487, USA CTX01-15604X3. The Kroklaw-Walton generator (herein only one stage, as indicated by the dashed box 10 1〇0) can be expanded by connecting more of the same level if necessary, until the output voltage is The required range is reached on this output, labeled "Output (HV), in Figure 12. At the initial startup of the power supply, the voltage on the feedback pin is zero, and thus the oscillator is ΜΑΧ 761 controls the wafer to be turned on. At the rectified output of the voltage transformer and the charge pump, the voltage rapidly rises to several thousand volts] and the voltage ratio is fed back to the feedback pin. When the feedback pin is on When the voltage reaches a predetermined voltage, the ΜΑΧ761 turns off the oscillator. When the output voltage is sufficiently lowered to reduce the voltage on the feedback pin, the MAX761 turns on the oscillator and the cycle is repeated, and the ΜΑχ76ι allows a brief 20 Oscillation bursts to maintain the desired output voltage. Turtle's device typically causes very small currents, such as less than 5μΑ at 4°, in which case the oscillator only needs to be short pulse length (when Pulse delay approx. 1 Typically 5 ms is less than 1 ms, preferably less than 5 〇〇 ^, and more preferably 250 (4) is turned on, resulting in the power supply 1 〇 requiring 34 200808452 very low average current from the power supply 11. When in electrospray Approximately 4.9 kV of output power is generated on the site. According to the present invention, the power supply can cause an average current as small as 25 mA from a 6V power supply. For continuous spraying at a flow rate of approximately 5 g/day. In the case of an electrostatic spray device as exemplified by the dispersing device disclosed in European Patent No. U99,265, the power supply 1 described in this example is based on an active element. Efficient dispersion produces a stable _ spray without observable deposition. The power supply 10 can be used in combination with an electrospray, for example, to provide the following: fragrance dispersion or deodorization Agent, sterilizing agent, sterilizing AJ (fungicide), air disinfectant, bactericide plus gamma), antiviral agent, w agent, pharmacy, therapeutic agent, drug, stimulant, relaxant, analgesic Anesthetics, antidepressants, organisms such as vitamins, hormones, chemical signaling substances, neurotransmitters, blood fractions, amino acids, peptides, polypeptides, proteins, DNA, RNA or other forms of nucleic acids. • Many other possibilities In application, the power supply 1〇 can also be used in the following products: removing smoke, bacteria, viruses, fungus, pollen, dust, household dust mites, jumping particulate allergens and other airborne bodies in the air. 20 This power supply 10 is ideal for products that are used in extreme environments, examples of which include, but are not limited to, in public places, restrooms, ventilation systems, in transportation vehicles, and portable personal devices ( For example, perfume spray), air cleaner on the itn and similar devices, air disinfectant, air freshener #1 and / or chemical points Id and the t road can be used for 35 200808452 early strike, multi-shot, timing In a space, burst or continuous system, this depends on the needs of the application. The activation of the atomizing device is achieved by consuming the power source 11 to the power supply unit 1 . The coupling can be formed by a physical device (eg, a user-initiated .5 switch). Alternatively, the consuming can be formed merely by betting the power source into the =source provider 1G. After the device is activated, the atomization provided by the voltage across the spray and reference electrodes can be conveniently controlled by a (four)-step start or stop switch. The switches are optionally programmed to - Integral circuits (for example - programmable logic devices (pLD). 10...
