Spraying apparatus enabling large-volume generation of particles minute to a Brownian-motion engendering level. The spraying apparatus includes an atomization tank, an atomizing device, a blower, an atomization unit furnished with a liquid-level sensor for measuring liquid level in the atomization tank, a tank unit for supplying liquid formulation to the atomization tank, and a control unit for controlling supply of the liquid formulation from the tank unit to the atomization tank. If the liquid level measured by the liquid-level sensor falls below a predetermined first level h.sub.1, the control unit starts supply of the liquid formulation from the tank unit to the atomization tank, and if the liquid level measured by the liquid-level sensor reaches a predetermined second level h.sub.2 higher than the first level h.sub.1, the control unit halts supply of the liquid formulation from the tank unit to the atomization tank.

There are provided methods for treating a gas having an undesirable odor. The methods comprise contacting the gas with an acidic aqueous oxidizing composition having a pH of about 2.0 to about 3.0 and comprising at least one cation of a metal; a sequestering agent; and H.sub.2O.sub.2 and submitting the gas and the composition to UV radiation when the gas and the composition are contacting each other, wherein the treatment permits to reduce by at least 60% intensity of the undesirable odor.

A decontaminating filter table for decontaminating exhaled or ambient air is provided. The table includes an input air grille; a first air trough in fluidic connection with the input air grille; a second air trough in fluidic connection with the first air trough; and a HEPA filter for filtering the decontaminated air. The table also includes an air mover for drawing the exhaled air through the first and second air troughs and through the HEPA filter. In addition, the table includes a scrubber for decontaminating the exhaled air and a visual/audio indicator for monitoring air flow through the first and second troughs.

A portable scent dispensing ashtray includes an enclosure and a lid. The enclosure comprises an ash retaining portion, an absorbent retaining portion, and a dispenser retaining portion. An absorbent is retained by the absorbent retaining portion. A dispenser is retained by the dispenser retaining portion and stores odor neutralizing matter that is to be absorbed by the absorbent. The lid is rotatably attached to an upper end of the enclosure such that the lid opens or closes. When the lid opens, the ash retaining portion is exposed allowing ash or waste to be deposited into or removed from the ash retaining portion. When the lid closes, the lid activates the dispenser causing the odor neutralizing matter to be released and absorbed by the absorbent. The ashtray is portable and fits into any standard cup holder. The ashtray automatically provides odor neutralization without having to carry a separate odor neutralizing spray.

An atomizing diffuser for gaseous environment cleaning: includes a tank cover covered in a water tank to define an oscillation space in the tank cover so as to enhance the effect of oscillating atomized liquid, a housing shield shielding the tank cover and provided with a water filling hole for allowing direct filling of liquid in the water tank and the oscillation space, and an oscillation device with the oscillator thereof coated with a layer of acid and alkali resistant coating for oscillating the alkaline ionized water and other acid-alkaline cleaning liquids in the oscillation space into gaseous cleaning mist that is outputted to the external environmental space for sterilization, cleaning, deodorization, virus elimination, or air purification, and an umbrella-shaped panel with radial ribs provided in the housing is illuminated by light to show the beauty of a paper umbrella, matching the spray effect.

The present invention is directed to an electrostatic sprayer for applying disinfectants, agricultural production, pesticides, and other chemicals and liquid solutions. The electrostatic sprayer may be used for indoor and outdoor applications. The electrostatic sprayer provides a solution tank for holding a treatment solution, a base for holding and protecting the mechanical and electrical components, including a power supply, solution pump, and electrostatic generator, of the electrostatic sprayer, a supply hose, and a spray wand. The solution tank further includes input and exit filters to remove particles that may damage the solution pump of clog the spray wand. The spray wand includes spray nozzles with backflow valves and metering disks to control the flow of the treatment solution and close the valve when the treatment solution is not sufficiently pressurized to pass through the backflow valve to prevent leak when not in use. An electrostatic switch is also provided for selectively powering on the electrostatic generator. The electrostatic generator provides a positive charge to an electrode in the solution tank and a negative charge to a grounding strip in the handle of the spray wand providing a negative pathway through Earth to the objects being treated enhancing the electrical attraction of the treatment solution to those items. A grounding strap is also provided to be worn by the user to reduce the resistance in the path between the grounding strip and Earth by bypassing some of the user's clothing and protective gear that may provide resistance to the path.

A disinfection apparatus and method is provided for disinfecting a fluid. The apparatus elements define three internal container volumes. Fluid is introduced into an entry volume where its flow is conditioned to reduce splash and slow the fluid flow. The fluid is then channeled into a disinfection volume where a disinfection unit delivers a disinfection agent to the fluid. Finally, the fluid exits the apparatus through an exit volume. In one aspect, a sink-trap is disclosed in which wastewater liquid contacts a pair of diverters. The diverters have conditioned contact surfaces that slows and spreads the liquid flow and reduces liquid splash. The wastewater then passes through a UV chamber in which it is disinfected. The liquid then exits the sink-trap. Advanced self-cleaning apparatus are additionally disclosed to clean and disinfect the sink-trap and trapped wastewater. The entire apparatus operates under computer control.
