Abstract
Abstract A water purifying apparatus includes a water line extending from a source to a nozzle and having a filter, a sanitizing element and a venturi in the line. An ozone generator is connected to the venturi to supply ozonated air to the water flowing through the line. The ozone sanitizes the nozzle as water is discharged into a bottle.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
167 words
Water purifying apparatus including a water line extending between a water source and a water dispensing nozzle; the line including first means for removing solids from the water flowing through the line, second means for killing bacteria in the water flowing through the line, the first and second means being located on the water line away from the nozzle, and a venturi located on the water line adjacent to the nozzle and having a low pressure port; an ozone generator; and an ozone line extending between the ozone generator and the low pressure port of the venturi whereby ozonated air from the generator is drawn into the water flowing through the water line at the venturi and is flowed with the water along the water line and out the nozzle to sanitize the nozzle, the water line including an inspection portion located between the venturi and the nozzle whereby bubbles of ozonated air entrained with the water passing through the water line are visible through such portion.
Claim 2
Dependent Claim
167 words
Water purifying apparatus including a water line extending between a water source and a water dispensing nozzle; the line including first means for removing solids from the water flowing through the line, second means for killing bacteria in the water flowing through the line, the first and second means being located on the water line away from the nozzle, and a venturi located on the water line adjacent to the nozzle and having a low pressure port; an ozone generator; and an ozone line extending between the ozone generator and the low pressure port of the venturi whereby ozonated air from the generator is drawn into the water flowing through the water line at the venturi and is flowed with the water along the water line and out the nozzle to sanitize the nozzle, the water line including an inspection portion located between the venturi and the nozzle whereby bubbles of ozonated air entrained with the water passing through the water line are visible through such portion.
Claim 3
Dependent Claim
17 words
Water purifying apparatus as in claim 1 wherein said portion is a length of light transmitting tubing.
Claim 4
Dependent Claim
99 words
Water purifying apparatus as in claim 1 wherein the ozone generator includes an elongate hollow body, third means for generating ozone in the body, an outlet port adjacent one end of the body and an inlet port adjacent the other end of the body and wherein the ozone line is connected to said outlet port whereby ozone is drawn out of one end of the body and into the ozone line, replenishment air flows through the inlet and into the other end of the body and along the interior of the body and is ozonated by the third means.
Claim 5
Dependent Claim
55 words
Water purifying apparatus as in claim 3 wherein the body includes end caps closing the ends of the body, said outlet port being located at one end cap and wherein said third means comprises an elongate ultra-violet bulb and including a bulb socket in the other end cap, said bulb being secured in said socket.
Claim 6
Dependent Claim
28 words
Water purifying apparatus as in claim 4 wherein said end caps each include U-fold means fitted over the ends of the body to secure the caps in place.
Claim 7
Dependent Claim
36 words
Water purifying apparatus as in claim 4 wherein said body is rectangular in cross section, said end caps are rectangular and each include four U-fold sides fitted over the ends of the sides of the body.
Claim 8
Dependent Claim
51 words
Water purifying apparatus as in claim 3 wherein said inlet port extends through a wall of said ozone generator and including an eye-shield secured to said wall having a plate spaced from and overlying the inlet opening whereby light generated by said third means is indirectly visible through the inlet opening.
Claim 9
Dependent Claim
30 words
Water purifying apparatus as in claim 7 wherein said body includes end caps each including U-fold means fitted over the ends of the body to secure the caps in place.
Claim 10
Dependent Claim
37 words
Water purifying apparatus as in claim 8 wherein said body is rectangular in cross section, said end caps are rectangular and each cap includes four U-fold sides fitted over the ends of corresponding side of the body.
Claim 11
Dependent Claim
149 words
Water purifying apparatus including a water line extending between a water source and a water dispensing nozzle; the line including first means for removing solids from the water flowing along the line, second means for killing bacteria in the water flowed through the line, and a venturi having a low pressure port; and an ozone generator including a hollow body, third means for generating ozone within the body, an inlet port at one end of the body, an outlet port connected to the ozone line at the other end of the body, and an eye-shield mounted on the interior of the body having a plate spaced from the body and located between the inlet opening and the third means whereby light from said third means is indirectly visible through the inlet opening; and an ozone line extending between the outlet port and the low pressure port of the venturi.
Claim 12
Dependent Claim
149 words
Water purifying apparatus including a water line extending between a water source and a water dispensing nozzle; the line including first means for removing solids from the water flowing along the line, second means for killing bacteria in the water flowed through the line, and a venturi having a low pressure port; and an ozone generator including a hollow body, third means for generating ozone within the body, an inlet port at one end of the body, an outlet port connected to the ozone line at the other end of the body, and an eye-shield mounted on the interior of the body having a plate spaced from the body and located between the inlet opening and the third means whereby light from said third means is indirectly visible through the inlet opening; and an ozone line extending between the outlet port and the low pressure port of the venturi.
Claim 13
Dependent Claim
50 words
Water purifying apparatus as in claim 10 wherein the venturi is located on the water line adjacent the nozzle, the first and second means are located on the water line away from the nozzle, and a portion of the water line between the venturi and the nozzle is light transmitting.
Claim 14
Dependent Claim
17 words
Water purifying apparatus as in claim 11 wherein said portion is a length of light transmitting tubing.
