Solution applicator assembly with removable flow control insert

A solution applicator assembly, comprising:

• an upper body defining an upper channel;
• the upper body further including a primary inlet fluidly connected to the upper channel for receiving a solution;
• a lower body defining a lower channel being fluidly connectable to the upper channel to define a central channel;
• the lower body further defining a primary outlet fluidly connected to the lower channel;
• a flow control insert removeably receivable in the central channel for receiving and accelerating the solution from the upper channel and releasing the solution into the lower channel such that it may be emitted from the primary outlet;
• the flow control insert having a fluid passage extending therethrough for conveying the solution between the primary inlet and the primary outlet, the flow control passage having a primary intake for receiving the solution and a control outlet for emitting the solution;
• the flow control insert having one or more air injection holes extending into the fluid passage between the primary intake and the control outlet for conveying air into the flow control insert for mixing the air with the solution;
• the flow control insert defining a chemical opening extending into the fluid passage between the primary intake and the control outlet for receiving a chemical to mix the chemical with the solution;
• and
• the upper body and the lower body removeably connectable to one another to selectively allow the flow control insert to be removed and positioned in the central channel.
