    Abstract: An electrostatic painting method is disclosed in which air inside a paint feed channel is expelled when a color for painting is changed. An electrically conductive paint is channeled into a discharge channel of a fluid pathway, and the flow rate of the paint is measured. The fluid pathway is provided, via a paint valve, to a color changing valve mechanism, and communicates with a paint cartridge. The changing valve mechanism is provided in a distant position relative to a painting gun. Electrically conductive paint is channeled through a paint feed channel, which extends from the color changing valve mechanism to the painting gun, and air inside the paint feed channel is expelled. The paint feed channel is then filled with the electrically conductive paint according to the value measured for the flow rate.

  • Publication number: 20100001105
    Abstract: This invention relates to a humidification system for delivering atomized water to an object. In a humidification system of the invention for delivering humidified air to an object, the object is efficiently humidified. A humidification system (1) of the invention is provided with an electrostatic spraying device (2) for discharging water in an electrically charged and atomized state. When electrically charged water droplets discharged from the electrostatic spraying device (2) approach a person (P), these water droplets are attracted to the person (P) by electric image force. In this way, the water in atomized form is efficiently absorbed by or adhered to the object (P).

  • Publication number: 20100000240
    Abstract: An electrostatically atomizing unit for use in a temperature regulating appliance to add a function of generating a mist of charged minute water particles for deodorization and/or sterilization of a temperature-regulated space. The appliance has a cold space of which air is cooled by cooling means and is fed to cool the temperature-regulated space divided from the cold space by a partition. The atomizing unit has an emitter electrode which is configured to condense water from within a surrounding air. A high voltage source applies a high voltage to the emitter electrode to atomize the condensed water into the charged minute water particles which are discharged from the emitter electrode into the temperature-regulated space. The emitter electrode is provided with a cooling coupler which establishes a heat transfer relation through the partition to the cold space to cool the emitter electrode by making the use of the cooling means inherent to the appliance.

  • Publication number: 20090314861
    Abstract: Fluid ejection using multiple voltage pulses and removable well modules is provided. Ejection of an electrically conductive fluid is accomplished by the application of two or more high voltage pulses. The high voltage pulses are applied across a conducting nozzle for transporting the fluid and a grounded conducting ring positioned below the nozzle. Ejected fluid droplets fall through the center of the conducting ring and onto a substrate. The presence and approximate size of the ejected droplets can be sensed and used for feedback for the high voltage pulses. The conductive fluids are stored in well modules that are not permanently attached to a well plate. Each removable well module includes a conducting nozzle and can include valves and a memory chip. Control circuits are also provided to independently control the high voltage pulses applied to the individual well modules.

    Abstract: A high voltage is applied between an emitter electrode in an atomizing barrel and an opposed electrode supported to the atomizing barrel to electrostatically atomize a liquid supplied to the emitter electrode into a mist of charged minute particles. A silencer duct is attached to the front end of the atomizing barrel for reducing noises developed when generating the mist of the charged minute particles. Accordingly, the silencer duct can absorb the noises developed around the emitter electrode and the opposed electrode at immediately downstream thereof for effectively reducing the noises.

  • Patent number: 7621470
    Abstract: Water is fed from a tank to a capillary carrier having an emitter end from which an ionized water particle is emitted by a voltage being applied across the emitter end and an opposed electrode. A cation exchanger is provided to remove minerals such as Ca2+ and Mg2+ from the water being fed through the capillary carrier or from the water to be fed to the carrier from the tank, thereby avoiding the ions from precipitating at the emitter end as CaCO3 or MgO in reaction with CO2 in the surrounding air, and therefore assure reliable electrostatic atomization over a long period of time.

    Abstract: Total supplied current (I2) and high voltage (Vm) supplied to a rotary atomizer head (5) are detected by a total current sensor (115) and a high voltage sensor (116). Total leak current (I2) in paint paths, thinner paths and air paths inside an electrostatic atomizer (2) is detected via a metal back plate (40) of the electrostatic atomizer (2). When the total leak current value (I2) exceeds a threshold value (Ia), the level Vm of the high voltage applied to the rotary atomizer head (5) is lowered stepwise.

  • Patent number: 7614572
    Abstract: An electrostatic spraying device has a removable cartridge with a reservoir containing a volume of liquid compositions to be electrically sprayed. The reservoir is deformable according to inner pressure and configured to provide a removable cartridge. The device includes a dispensing unit for spraying the liquid composition. The dispensing unit includes a nozzle for dispensing the liquid composition and an emitter electrode which charges the liquid composition for electrostatically spraying the liquid composition out through the nozzle. A suction pump is integrated into the dispensing unit in an immediately upstream relation with the reservoir for feeding the liquid composition from the reservoir to the nozzle. Thus, the suction pump can be concentrated together with the emitter electrode and the nozzle into the dispensing unit on one end of the reservoir, enabling to realize the cartridge of a compact design.

  • Publication number: 20090272827
    Abstract: An emitter electrode is cooled by a cooler to generate condensed water which is charged by a high voltage applied between the emitter electrode and an opposed electrode and is discharged as a mist of charged minute water particles. A controller is provided to vary a temperature drop to a predetermined minimum temperature in dependence of an environmental temperature detected by a temperature sensor. The temperature drop is made variable in proportion to the environmental temperature. Accordingly, a sufficient amount of water can be condensed on the emitter electrode simply by controlling the cooling of the emitter electrode without relying upon an environmental humidity.
