A hand-held dispenser to dispense fluid includes a casing to fit into a hand of a user, a nozzle in the casing to dispense a mist, a fluid reservoir contained in the casing to hold a fluid to be turned into the mist, a filament extension atomizer contained in the casing to generate the mist, an air source contained in the casing to provide air flow to direct the mist to the nozzle, a motor contained in the casing to operate the filament extension atomizer, an actuator positioned on the casing to activate the dispenser, a control circuit contained in the casing to receive a signal from the actuator and to send a signal to the motor to cause the motor to actuate, and a power source contained in the casing to provide power to the motor upon receive a signal from the control circuit.

A fluid sprayer includes a pump motor, a piston, a pump housing, and an outer housing. The piston is reciprocatable by the pump motor. The pump housing comprises a pump chamber housing disposed to receive the piston, and a plurality of alignment pins extending laterally away from the pump chamber housing. The outer housing surround and anchors the pump motor, and has a plurality of internal lateral bores disposed to slideably receive and retain the alignment pins, such that the pump housing is free to self-align with the piston.

An adapter (14) allows direct connection of a handheld spray device (10) to paint cans (12, 12A, 12B, 12C), of varying dimensions. The adapter (14) includes a cage (60) for holding the paint can (12, 12A, 12B, 12C), a cap (62) that connects the cage (60) to the handheld spray device (10), and a gasket (64) that seals the open upper end of the paint can (12, 12A, 12B, 12C) to the cap (62). The adapter (14) may also include a suction tube extension 66 that is connectable between the pump inlet (52) and the suction tube (54) of the spray device (10).

A handheld fluid sprayer (10) is configured to draw spray fluid from a reservoir (14) mounted on the fluid sprayer and eject the spray fluid through a nozzle (32). The reservoir is removably mounted to the fluid sprayer. A filling apparatus can connect to the reservoir at the same interfaced that the reservoir (14) connects to the fluid sprayer (10). The filling apparatus can be used to refill the reservoir (14).

A fluid sprayer includes a pump and an electrostatic module configured to provide an electrostatic charge to spray fluid. The electrostatic module is electrically connected to a conductive component of the fluid sprayer, such as a fluid displacement member, fitting, cylinder, or spray tip, to charge the spray fluid via the conductive component. The fluid is electrostatically charged prior to exiting the fluid sprayer.

Methods, apparatuses and systems are disclosed including a method of filling a container with substantially only a liquid. The method can include the removal of a gas from the container prior to, during or after the filling of the container with the liquid. According to one embodiment, the container includes an inner liner and a lid. The method includes providing a volume defined by at least the inner liner and the lid of the container. In such embodiment, the liquid can initially be contained within a first portion of the volume and a remaining portion of the volume can contain a gas. The method can include removing substantially all the gas from the volume via one or more ports that communicate with the volume while retaining substantially only the liquid within the volume.

A discharge container 1 includes a container body having a discharge face 13, on which a discharge hole 15 is formed, a cylinder part including a discharge space 2 in communication with the discharge hole 15 inside the container body, a piston 3 movable between a first position and a second position, the second position being farther than the first position from the discharge face in the discharge space 2, and a plurality of storage portions 5a to 5e for storing contents, wherein a plurality of inlet holes respectively corresponding to the plurality of storage portions 5a to 5e are formed in an inner wall of the discharge space 2, wherein, when the piston 3 is at the second position, the plurality of inlet holes 22a to 22e communicate with the discharge space 2 between a top face of the piston 3 and the discharge face, and the contents are ready to flow into the discharge space 2 from the plurality of inlet holes 22a to 22e, and wherein, when the piston 3 is at the first position, the plurality of inlet holes 22a to 22e are closed by the piston 3.

A pump draws fluid from a reservoir and drives the fluid downstream to a spray tip where the fluid is applied to a surface. A piston is driven in a reciprocating manner to pump the fluid. A check valve is disposed downstream of the piston to regulate a flow of the fluid downstream from the piston. The pump is initially dry and is primed with fluid prior to operation. To facilitate priming, the piston is dimensioned to impact the ball and unseat a valve member of the check valve during a priming stroke, thereby ejecting any air from the pump through the check valve. With the air ejected from the pump, a vacuum is formed during a suction stroke of the piston, which draws fluid downstream from the reservoir to prime the pump.

A fluid dispensing device includes a housing and a reciprocating piston fluid pump coupled to the housing. The reciprocating piston fluid pump includes a piston. The piston is configured to pressurize at least one pumping chamber. A motor is connected to the reciprocating piston fluid pump to actuate the piston. A spray tip connected to an outlet of the at least one pumping chamber.

Disclosed is an intelligent device for outputting liquid, including: a base and a cover body. The base extends into the liquid bottle, a cavity body is provided in the base for accommodating one or more of a pump, a motor and a power supply, the pump or/and the power supply is/are connected to a control assembly, a distance from a joint point of the cover body and the liquid bottle to a top surface of the cover body is less than a distance from a bottom surface of the base to the top surface of the cover body, and the cover body is connected to the base.
