Cleaning machine (100) comprising a nebuliser device (10) for nebulising a liquid product (115), a tank (110) containing said liquid product (115), an intake part (120) comprising at least one waste air vent (125), wherein said nebuliser device (10) comprises a dispenser (20) for dispensing said liquid product (115), a first connecting duct (211) which connects in fluid communication said tank (110) with said dispenser (20), a second duct (225) which connects in air-flow communication said at least one waste air vent (125) of said intake part (120) with said dispenser (20), wherein said dispenser (20) comprises a hollow body (21) comprising an inner cavity (25) connected in air-flow communication with said second duct (225), a dispensing tube (30) connected in fluid communication with said first duct (211), wherein a space is provided forming a nebulisation area (40) arranged at a mouth of an outlet pass-through opening of said dispensing tube (30) and at a mouth of a pass-through outlet opening of said inner cavity (25).

An atomizing assembly includes a tubing section having an inlet end and an outlet end. The inlet end of the tubing section is connectable to a liquid storage portion, and the outlet end of the tubing section is in fluid communication with an atomizing nozzle. The tubing section is configured to deliver a flow of liquid aerosol-forming substrate through the atomizing nozzle. The atomizing nozzle includes an air channel configured to establish an air flow through the nozzle. The air flow is mixed with the flow of liquid aerosol-forming substrate.

An oral care device (10) with a pump assembly (12) including: a plunger assembly (52) having a rack assembly (74); a compressible spring (64) configured to exert a forward force on the plunger assembly; and a rack and pinion assembly (72) configured to exert a force on the plunger assembly opposite the forward force, wherein the rack assembly includes a plurality of rack teeth (74 a . . . 74 g) and the pinion assembly (76) includes a plurality of teeth (78) arranged around a portion of the pinion; where the plurality of rack teeth include an angled front surface (86) and an angled rear surface (87), the front surface of at least some of the plurality of rack teeth including a different angle than the rear surface, and further where at least some of the plurality of rack teeth include a pointed or rounded tip (82).

The painting system comprises a paint brush, a brush hose, a pump, a power source, a cap, and a suction hose. Paint may be pumped from a paint can to the paint brush by the pump such that the paint brush may continuously apply the paint to a surface without necessitating that bristles of the paint brush be dipped into the paint can. The cap may couple to the top of the paint can to retain the suction hose in position within the paint can. A bristle attachment of the paint brush may be detached so that the bristle attachment may be cleaned or replaced. A sprayer attachment may be coupled to the handle in place of the bristle attachment and may be activated to spray paint the surface.

A sprayer system includes a sprayer head, at least two reservoirs, and a gripping portion. The reservoirs hold constituent components of a product. The product is emitted from a nozzle included in the sprayer head. The emission of the product results in the depletion of the components of one of the reservoirs to a greater extent than the remaining at least one reservoir and changes the center of gravity of the sprayer system.

A hand held spray dispenser in which air and liquid are pressurised towards a turbulence chamber and wherein air is introduced into the liquid adjacent to an inlet orifice of the turbulence chamber and the mixture passes through the inlet orifice into the turbulence chamber before being expelled through an exit orifice.

A mister apparatus includes a portable mister body having an air inlet and an air outlet, a fan configured to draw air in through the air inlet and force the air out the air outlet, a reservoir configured to contain a liquid, the reservoir having a reservoir outlet, a liquid outlet, the liquid outlet being disposed adjacent to or downstream of the air outlet, and a pump in fluid communication with the reservoir. The pump is operable to move the liquid from the reservoir and out of the liquid outlet such that the liquid exiting the liquid outlet enters into the air exiting the air outlet to form a mist.

An atomizing assembly includes a tubing section having an inlet end and an outlet end. The inlet end of the tubing section is connectable to a liquid storage portion, and the outlet end of the tubing section is in fluid communication with an atomizing nozzle. The tubing section is configured to deliver a flow of liquid aerosol-forming substrate through the atomizing nozzle. The atomizing nozzle includes an air channel configured to establish an air flow through the nozzle. The air flow is mixed with the flow of liquid aerosol-forming substrate.

An apparatus for cleaning a surface includes a liquid delivery system for storing cleaning liquid and delivering the cleaning liquid to the surface to be cleaned, and an indicator system that is operably coupled with the liquid delivery system to indicate an operational status to the user operating the apparatus. The indicator system can include a light emitter that illuminates when an operational status is detected. The light emitter can illuminate the container storing cleaning liquid.
