Abstract

An electrolytic ozone generator for use with a faucet and methods for assembling and using the same.

First claim

What is claimed is:

1. An ozone generator for use with a faucet, the ozone generator comprising:
a first housing;
a first current spreader operably coupled to the first housing, the first current spreader including a body and a terminal having an electrical connection to a first wire lead;
an overmolded material of the first housing sealing with the first current spreader between the body and the terminal;
a first electrode operably coupled with the body of the first current spreader; and
wherein the body of the first current spreader includes an opening that receives the first electrode, the first housing surrounding the first current spreader in a sealed manner between the terminal and the opening.

2. The ozone generator of claim 1 , further comprising:
a second housing;
a second current spreader operably coupled to the second housing, the second current spreader including a body and a terminal having an electrical connection to a second wire lead;
an overmolded material of the second housing sealing with the second current spreader between the body and the terminal;
a second electrode operably coupled with the body of the second current spreader; and
wherein the body of the second current spreader includes an opening that receives the second electrode, the second housing surrounding the second current spreader in a sealed manner between the terminal and the opening.

3. The ozone generator of claim 2 , further comprising a separator, wherein the first electrode is an anode, the second electrode is a cathode, and the separator is positioned between the anode and the cathode.

4. The ozone generator of claim 3 , wherein the anode and the cathode each includes a plurality of water passageways.

5. The ozone generator of claim 4 , further comprising a first frame that receives the anode, and a second frame that receives the cathode.

6. The ozone generator of claim 2 , wherein the terminal of the first current spreader includes tabs configured to be crimped on the first wire lead, and the terminal of the second current spreader includes tabs configured to be crimped on the second wire lead.

7. The ozone generator of claim 2 , wherein the terminal of the first current spreader has a rectangular cross-section, and the terminal of the second current spreader has a rectangular cross-section.

8. The ozone generator of claim 2 , further comprising:
an outer cartridge;
wherein the first housing and the outer cartridge cooperate to define a first water flow path across the first electrode;
wherein the body of the first current spreader is sealed from the first electrical connection between the terminal of the first current spreader and the first wire lead, and the first electrical connection is outside of the first water flow path;
wherein the second housing and the outer cartridge cooperate to define a second water flow path across the second electrode; and
wherein the body of the second current spreader is sealed from the second electrical connection between the terminal of the second current spreader and the second wire lead, and the second electrical connection is outside of the second water flow path.

9. An ozone generator for use with a faucet, the ozone generator comprising:
a first housing;
a first current spreader operably coupled to the first housing, the first current spreader including a planar body and a planar terminal having an electrical connection to a first wire lead;
an overmolded material of the first housing sealing with the first current spreader between the planar body and the planar terminal;
a first electrode operably coupled with the planar body of the first current spreader;
a second housing;
a second current spreader operably coupled to the second housing, the second current spreader including a planar body and a planar terminal having an electrical connection to a second wire lead;
an overmolded material of the second housing sealing with the second current spreader between the planar body and the planar terminal;
a second electrode operably coupled with the planar body of the second current spreader; a separator, wherein the first electrode is an anode, the second electrode is a cathode, and the separator is positioned between the anode and the cathode;
wherein the anode and the cathode each includes a plurality of water passageways;
the planar body of the first current spreader includes an opening that receives the first electrode; and
the planar body of the second current spreader includes an opening that receives the second electrode.

10. The ozone generator of claim 9 , further comprising a first frame that receives the anode, and a second frame that receives the cathode.

11. The ozone generator of claim 9 , wherein the terminal of the first current spreader includes tabs configured to be crimped on the first wire lead, and the terminal of the second current spreader includes tabs configured to be crimped on the second wire lead.

12. The ozone generator of claim 9 , wherein the terminal of the first current spreader has a rectangular cross-section, and the terminal of the second current spreader has a rectangular cross-section.
