The present disclosure provides a spray device and a cleaning apparatus. The spray device includes an atomization structure, which is configured to atomize a cleaning liquid when the cleaning liquid is sprayed to form liquid droplets, and a jet structure, which is configured to spray a gas along a determined direction to cause the gas sprayed to collide with the liquid droplets to form atomized particles. The spray device provided by the present disclosure may increase cleaning uniformity and cleaning efficiency to improve cleaning process results, and may further reduce an impact force to the to-be-cleaned surface by the liquid droplets to a certain level. Thus, the damage to a surface pattern of a wafer may be reduced.

A method for aerosolising a liquid comprises the steps of: providing an aperture plate having at least 100 outlet holes per mm.sup.2; delivering liquid to the aperture plate; and vibrating the aperture plate to produce an aerosol. The viscosity of the liquid is in the range of from 1 to15 cP and the surface tension of the liquid is in the range of from 72 to 0.5 mN/m. The output rate of the generated aerosol is greater than 0.01 mL/min.

The disclosure discloses a connection structure and a spray shower. A connection structure includes a first object, a buckle and a second object. The first object includes a connection channel and a sliding slot perpendicular to the connection channel. A retaining wall and a plug-in channel are provided between the sliding slot and the connection channel. An insertion buckle is provided with a buckle body slidable in the sliding slot and an insertion piece adapted to be inserted in or retracted from the connection channel through the plug-in channel. The second object is inserted into the connection channel and is provided with a recess matching the insertion piece. The spray shower includes the connection mechanism. The connection structure and the spray shower are mechanically connected.

A sprayer that senses the presence or character of a surface to be sprayed includes one or more sensors configured to detect a presence or character of a surface to be sprayed; and a dispenser assembly including one or more components configured to modify at least one spray characteristic of a formulation based on an input from at least one of the one or more sensors indicative of the presence or character of the surface to be sprayed.

An aerosol generator includes a container and an atomizing module arranged in the container. The container has a liquid chamber and an aerosol chamber respectively arranged at two opposite sides of the atomizing module. The atomizing module includes an annular vibration plate, a microporous member, and a circuit board. The vibration plate has a first hole, and the microporous member is disposed on the vibration plate and covers the first hole. The circuit board is electrically coupled to an electrical contact of the vibration plate. The circuit board is arranged at one side of at least part of the vibration plate, and the circuit board and the at least part of the vibration plate have a gap there-between. A projected region defined by orthogonally projecting the circuit board onto a plane overlapping with the electrical contact partially covers the least part of the vibration plate.

A fluid dispensing cartridge includes a housing body having a proximal end wall, a distal end wall, a fluid chamber, and a hollow throat portion. The fluid chamber is in fluid communication with the hollow throat portion. The proximal end wall provides a proximal termination of the fluid chamber and the distal end wall provides a distal termination of the hollow throat portion. A plurality of electrical contacts face proximally from the proximal end wall. The fluid dispensing cartridge includes a fluid jetting chip that has a plurality of fluid jetting nozzles.

A vehicle climate control system includes a heating, ventilation, and air conditioning (HVAC) system where condensate from the system is conveyed to a misting device disposed at an air-conditioned outlet in the cabin of the vehicle. The misting device can be arranged at the exit of the air-conditioned outlet such that conditioned air is conveyed by the HVAC ducting and mixes with the mist generated by the misting device at the air-conditioned outlet. The mist may be scented using an injection device that pumps a fragrant fluid into the misting device along with the condensate. Prior to conveying the condensate to the misting device, the condensate may be pumped through bacteria and sediment filter media providing a clean supply of condensate to the misting device. Positioning the misting device at the air-conditioned outlet helps prevent mold or debris from being trapped in the HVAC system or ducting.

An atomizer for applying a coating includes a nozzle plate, an actuator, and an acoustic focusing device. The nozzle plate defines at least one aperture. The actuator is configured to oscillate to form pressure waves within a fluid to eject the fluid from the nozzle plate. The acoustic focusing device focuses the pressure waves toward the apertures.

The present disclosure generally relates to the field of aerosol generation devices, and more particularly to electronic cigarettes configured to generation of aerosols from aqueous formulations of nicotine or cannabis products. The present disclosure further provides aqueous cannabinoid compositions for use in the aerosol generation devices.

An apparatus to provide scent or other substances (e.g., active agent) includes a thin profile delivery apparatus that includes an actuator (e.g., nebulizer) and drive circuit to generate a spray, aerosol or vapor. The apparatus may have a slot to removably a media cartridge that carries the scent or other substances. The apparatus may include two contacts (e.g., buttons), opposed to one another across a dimension of the apparatus. Activation may require both engagement of both contacts, for instance concurrently, or even successive engagement of both contacts, in quick succession. Activation may further require a correct orientation of the apparatus. The apparatus may have a form factor similar to a conventional credit or debit card, and may be pliable or pliably resilient. The delivery apparatus can be used in entertainment (e.g., food or cooking programming), and in healthcare (e.g., control of metabolism).
