초록 ▼

A mixing chamber for two fluid constituents is disclosed which provides improved mixing before the mixture is pushed through a mesh insert for the production of foam. Foam production using air and liquid is the basis of the exemplary embodiment though the disclosed mixing chamber could be used for any two fluid constituents. A single stream of air is diffused into a plurality of smaller streams of air. The single stream of liquid is directed into an annular sleeve resulting in a thinner wall of liquid flow as compared to the entering liquid stream. This annular sleeve of a thinner wall of liquid flow surrounds the plurality of smaller streams of air. In a second embodiment, there are individual streams of liquid which are directed inwardly toward the individual streams of air. The mixing chamber construction is disclosed herein can be used for any two fluid constituents which would benefit for more thorough mixing.

1. A mixing chamber for two fluid constituents comprising: a first flow conduit for a first fluid constituent;a diffuser positioned in said first flow conduit for directing flow of said first fluid constituent, said diffuser having a first free end, a second free end and a generally cylindrical body between said first free end and said second free end;a second flow conduit for a second fluid constituent;said first flow conduit being in flow communication with said second flow conduit for a flow of second fluid constituent to be arranged in a flow pattern around said diffuser;a mixing pocket constructed and arranged for receiving said two fluid constituent flows; andwherein said diffuser having an outer surface and being constructed and arranged with an overall axial length extending from said first free end which faces the flow of said first fluid constituent to said second free end which is adjacent said mixing pocket, wherein the directed flow of said first fluid constituent flows over said outer surface for the entirety of said overall axial length. 2. The mixing chamber of claim 1 wherein said first end of said diffuser having a proximal portion which faces said flow of said first fluid constituent. 3. The mixing chamber of claim 1 wherein said first fluid constituent is air. 4. The mixing chamber of claim 1 wherein said second fluid constituent is liquid. 5. The mixing chamber of claim 1 wherein said diffuser defines a plurality of flow channels in said outer surface. 6. The mixing chamber of claim 1 wherein the second end of said diffuser includes a tapered skirt. 7. The mixing chamber of claim 6 wherein said skirt is frustoconical in shape. 8. The mixing chamber of claim 6 wherein said skirt defines a plurality of flow channels. 9. The mixing chamber of claim 1 wherein said first flow conduit defines a flow space around said diffuser. 10. A dispensing device comprising: a liquid reservoir for retaining a liquid;a first supply for delivering liquid from said liquid reservoir to a remote site;a second supply for delivering air to said remote site;a housing which is constructed and arranged in communication with said first supply and with said second supply;a mesh insert assembled into said housing; anda mixing chamber which is received within said housing, said mixing chamber including an air diffuser and a mixing pocket wherein said mixing pocket is positioned between said air diffuser and said mesh insert, said air diffuser being constructed and arranged with a first free end, a second free end and a generally cylindrical body between said first free end and said second free end, said air diffuser being positioned in said second supply wherein said first free end having a proximal surface facing an incoming flow of air for directing said flow of air over said proximal surface wherein said mesh insert is spaced apart from and positioned exteriorly of said diffuser. 11. The dispensing device of claim 10 wherein said remote site is located within said mixing chamber. 12. The dispensing device of claim 10 wherein said diffuser defines a plurality of flow channels extending along a diffuser body. 13. The dispensing device of claim 10 wherein said diffuser includes a tapered skirt disposed at one end of said diffuser. 14. A dispensing device comprising; a housing defining an air flow path and a liquid flow path;air delivery means for delivering air to said air flow path;liquid delivery means for delivering liquid to said liquid flow path;a mixing chamber including an air diffuser, wherein said air diffuser being constructed and arranged with a first free end, a second free end and a generally cylindrical body between said first free end and said second free end, said first free end having a proximal surface which faces a flow of said air; andwherein said housing is constructed and arranged to direct a flow of liquid radially inwardly to engage said air diffuser and wherein the mixing of air and liquid occurs exteriorly of said diffuser. 15. The dispensing device of claim 14 wherein said air diffuser defines a liquid flow groove. 16. The dispensing device of claim 14 which further includes a mixing pocket and a mesh insert wherein said mixing pocket is axially positioned between said air diffuser and said mesh insert. 17. A mixing chamber for two fluid constituents comprising: a first flow conduit for a first fluid constituent;a diffuser positioned in said first flow conduit for dividing flow of said first fluid constituent into a plurality of flow streams, said diffuser having a first free end, a second free end and a generally cylindrical body between said first free end and said second free end;a second flow conduit for a second fluid constituent;said first flow conduit being in flow communication with said second flow conduit for a flow of second fluid constituent to be arranged in a flow pattern which surrounds said diffuser; anda mixing pocket constructed and arranged for receiving said two fluid constituent flows, wherein said first free end having a proximal surface with a tapered shape, said proximal surface being received in said first flow conduit and facing said flow of said first fluid constituent, wherein said first and second flows move past said second free end before entry into said mixing pocket. 18. The mixing chamber of claim 17 wherein said diffuser includes a tapered skirt disposed at said base end of said diffuser. 19. A dispensing device comprising: a housing defining an air flow path and a liquid flow path;a mesh insert received by said housing;air delivery means for delivering air to said air flow path;liquid delivery means for delivering liquid to said liquid flow path;a mixing chamber constructed and arranged to receive a flow of air and a flow of liquid;an air diffuser positioned in said air delivery means, wherein said air diffuser having a tapered surface at a first free end which faces a flow of said air; andwherein said air diffuser further including a tapered skirt at an opposite free end for directing air into a flow of said liquid and a generally cylindrical body between said first free end and said opposite free end, wherein said mesh insert is spaced apart from and positioned exteriorly of said diffuser. 20. The dispensing device of claim 19 wherein said air diffuser defines an air flow groove. 21. The dispensing device of claim 19 which further includes a mixing pocket which is axially positioned between said air diffuser and said mesh insert.
