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.

A soap dispenser can be configured to dispense an amount of liquid soap, for example, upon detecting the presence of an object. Certain embodiments of the dispenser include a housing, reservoir, pump, motor, sensor, electronic processor, and nozzle. In certain embodiments, the sensor can be configured to generate a signal based on a distance between an object and the sensor. In certain embodiments, the electronic processor can be configured to receive the signal from the sensor and to determine a dispensation volume of the liquid. The dispensation volume can vary as a function of the distance between the object and the sensor. The processor can be configured to control the motor to dispense approximately the dispensation volume of the liquid.

The bottle and spray assembly is a device that is designed pump liquids through a nozzle. The pump of the bottle and spray assembly is manually operated. The bottle and spray assembly is designed to rest on the arm of the user while the user holds a handle. The placement of bottle and spray assembly is in such a manner that the arm holds the bottle and spray assembly in place while the user pulls on the handle. The motion of pulling the handle operates the pump action within the spray assembly, which pumps the liquid through a nozzle. The bottle and spray assembly comprises a bottle and a spray assembly.

A pre-push miniaturized atomizing device has blank cap fixed to the outer diameter of pump nozzle underneath L-shaped water inlet of body. The blank cap and elastic body are fastened to the hole on the side of a large ring of body, the elastic body water outlet hole has a fastened and fixed valve needle, the thru-hole is connected to piston cavity in body, the outer diameter of the elastic body water outlet hole is set against the inner wall underneath the piston cavity at the L-shaped water inlet hole of the body to form a spray hole clearance. As the valve needle floats up and down in the water outlet hole, the clearance passage between the valve needle and elastic body opens or closes, while the spray hole clearance between the elastic body and the piston cavity closes or opens as corresponding to the deformation of the elastic body.

A hand-held integral airbrush comprising a shell provided with a grab handle, wherein an upper accommodating cavity and a lower accommodating cavity are formed in the shell, wherein an airbrush assembly is arranged in the upper accommodating cavity of the shell, and wherein an air pump assembly is arranged in the lower accommodating cavity of the shell and is used for pumping compressed air into the airbrush assembly, wherein the hand-held integral airbrush further comprising a switch part, an operating button which comprises a first control part and a second control part, wherein an air pump and an airbrush are integrated in a the ergonomically designed grab handle, and wherein the air pump and the airbrush are controlled by the trigger-type operating button.

Apparatus and methods for variable-control fragrance dispensing. The disclosed device brings customization to the fragrance industry. Interchanging sub-containers and selecting the amounts of each sub-container allows a user to customize their scents. A mixing chamber contained to receive and mix a variable amount of each liquid from a plurality of sub-containers is described. The mixed liquid is sprayable out a spray head of the device. Selector knobs may be used to control valves which control the variable amount of each liquid dispensed.

Provided is a fluid container including: a container main body, of which one side is open, configured to store a fluid; a housing having an outlet provided at one side and in which the container main body slides in a longitudinal direction; and a pump module coupled to the open one side of the container main body and configured to discharge the fluid to the outlet by sliding the container main body.

An all-plastic emulsion pump, includes a body, threads, pressing head, main column, suction tube, plastic spring, pull rod, stopper, lock cover, first and second one-way valve devices made of plastic material. A communication port is between the plastic spring and the main column. The pull rod is in the plastic spring. The stopper is connected to the pull rod upper end. When the plastic spring is pressed, there is a gap between the pull rod and the side wall of the communication port. When the plastic spring pops up, the stopper blocks the communication port. The first one-way valve device is between the pressing head and the main column to supply the emulsion to the pressing head. The second one-way valve device is between the plastic spring and the inlet of the body to supply the emulsion from the inlet of the body into the plastic spring.
