First Claim
Patent Images
1. A spray nozzle for use with a surface cleaning apparatus, comprising:
- a primary solution line having an inlet for receiving a primary solution and an exit orifice;
at least one secondary solution exit orifice associated with at least one secondary solution; and
wherein the primary solution is forced through the primary solution line, out the primary solution exit orifice and past the at least one secondary solution exit orifice thereby inducing flow of the at least one secondary solution out of the at least one secondary solution exit orifice.

Abstract
The present invention relates generally to a spray nozzle that is configured to mix at least two cleaning solutions and then to apply the mixed cleaning solutions to a surface to be cleaned. Furthermore, the spray nozzle can be configured to mix the at least two cleaning solutions at various ratios, thereby creating a customized cleaning solution for each type of surface that is to be cleaned.

12. A spray nozzle for use with a surface cleaning apparatus, comprising:
-
a primary solution line having an inlet and an exit orifice, wherein a primary solution under pressure is forced through the line out the exit orifice;
a selection chamber having an inlet in fluid communication with the primary solution line exit orifice and a plurality of exit orifices; and
a plurality of secondary solution exit orifices adapted to transmit a plurality of secondary solutions, wherein the selection chamber controls an amount of primary solution passed across each of the plurality of secondary solution exit orifices thereby inducing a flow of at least one of the plurality of secondary solutions. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A spray nozzle for use with a surface cleaning apparatus, comprising:
-
a means for distributing a primary solution;
a means for distributing a secondary solution;
a means for forcing the primary solution out of the means for distributing the primary solution and past the means for distributing the secondary solution such that the secondary solution is siphoned out of the means for distributing the secondary solution; and
wherein the means for distributing the primary and secondary solutions are open to atmospheric pressure. - View Dependent Claims (24, 25, 26)
