Embodiments of a spray gun incorporating a needle for applying multiple component materials are provided. In accordance with certain embodiments, the spray gun includes a fluid delivery tip assembly comprising an inner passage, a hollow needle disposed within the inner passage of the fluid delivery tip assembly, wherein the hollow needle comprises at least two indentions along an outer circumferential surface of the hollow needle near an end of the hollow needle, a first passage configured to deliver a first spray fluid to a fluid tip exit of the fluid delivery tip assembly, wherein the first passage is defined by a volume between the fluid delivery tip assembly and the hollow needle, and a second passage through the hollow needle, wherein the second passage is configured to deliver a second spray fluid to the fluid tip exit of the fluid delivery tip assembly.

A shower head assembly for cleaning fluid integration that includes: a shower head, where the shower head is attachable to a water pipe; a connector at a connection end of the shower head, where the connector connects the shower head to a water pipe; a first nozzle extending from a first side of a connector attached to the end of the shower head; a first tube extending from the first nozzle into a bottom of a first canister; a second nozzle extending from a second side of a connector attached to the end of the shower head; and a second tube extending from the second nozzle into a bottom of a second canister, wherein in the first canister and second canister includes a cleaning fluid and said cleaning fluid flows through each respective tube into water flow through the connector. The first nozzle enables release of cleaning fluid from the first canister to the first tube and the second nozzle enables release of cleaning fluid from the second canister to the second tube. In one particular embodiment, the first canister includes a body wash and the second canister includes a shampoo.

A device for administering fluid compositions includes a housing having a first end with an opening. The housing includes a compartment, proximate to the first end, that is capable of holding a liquid reservoir that is at least partially filled with a fluid. The device includes an air pump positioned within the housing, at a second end. The device includes an actuator positioned between the compartment and the air pump. The actuator includes an extendible piston that is configured to extend laterally toward the compartment. During device operation, the actuator causes the piston to extend towards the liquid reservoir and exert a force on the liquid reservoir. The force causes the fluid to be expelled from the liquid reservoir at the first end. The air pump is configured to atomize the fluid at the first end as it is expelled from the liquid reservoir.
