Apparatus for converting a powered air blower to a sprayer is disclosed. The apparatus comprises at least one discharge port terminating in a nozzle and at least one clamp, such as an alligator jaw. The clamp may open in a direction away from a direction of discharge from each nozzle. The clamp and the at least one discharge port may be mounted on a chassis having a configuration of a tube. A feed conduit is in fluid communication with each of the discharge port. Where there is more than one discharge port, the feed conduit splits to supply each discharge port. In an embodiment, there is one discharge port having a direction of discharge and an associated axis, and at least two clamps symmetrically disposed about the axis. The apparatus may be clamped to a discharge conduit of the blower.

A dispenser includes a housing defining an internal volume. A cartridge is coupled with the housing. A tube extends into the internal volume of the housing. A first liquid is drawn from the internal volume into the tube through a first inlet in the tube when the pump assembly is actuated. A connecting member is positioned in the internal volume of the housing and coupled to the cartridge and the tube. A second liquid is drawn from the cartridge, through the connecting member, and into the tube through a second inlet in the tube when the pump assembly is actuated.

An adjustable jet valve includes a valve body containing a cold water opening, a hot water opening and a mixed water opening for outputting mixed water; a spray nozzle arranged in the valve body includes a cold water inlet and a cold water outlet connected to a cold water channel of a valve by means of the cold water opening; a spray needle assembled inside the spray nozzle forms a cold water inflow space with an inner chamber of the spray nozzle, and forms a cold water spray outlet with the cold water outlet of the spray nozzle; and a throat pipe connected to the mixed water opening of the valve body for guiding the mixed water to flow into a device using mixed water.

A dispenser includes a housing, a cartridge, and a pump assembly. The housing has a first liquid disposed therein, and the cartridge has a second liquid disposed therein. The pump assembly includes a tube. The first liquid is drawn from the housing into the tube through a first inlet in the tube when the pump assembly is actuated, and the second liquid is drawn from the cartridge into the tube through a second inlet in the tube when the pump assembly is actuated. The first and second liquids are combined within the tube to form a mixture.
