Abstract

A device and system for purifying a fluid is provided. The system includes a tank having an interior space and a media container disposed within the interior space. A valve is provided that cooperates with an element within the interior, the valve being movable between an open and a closed position. The valve being biased to the open position when the element is not positioned within the interior space, wherein the interior space is fluidly coupled to the atmosphere in the open position. The valve further being configured to move to a closed position when the element is positioned within the interior space.

First claim

What is claimed is:

1 . A water purification system comprising:
a tank having an interior space; a media container disposed within the interior space; and a valve that cooperates with an element within the interior, the valve being movable between an open and a closed position, the valve being biased to the open position when the element is not positioned within the interior space, wherein the interior space is fluidly coupled to the atmosphere in the open position, the valve being configured to move to a closed position when the element is positioned within the interior space.

2 . The system of claim 1 , wherein element cooperates with the media container.

3 . The system of claim 1 , wherein the element is integral with the media container.

4 . The system of claim 1 , wherein the pressure relief valve comprises:
a first valve member movingly coupled to a cover, the cover being removably coupled to the tank; a second valve member movingly coupled to the first valve member, the second valve member being disposed to engage at least a portion of the media container when the cover is coupled to the tank; and a biasing member disposed between the first valve member and the second valve member, the biasing member biasing the second valve member towards an unsealed position.

5 . The system of claim 4 , wherein the pressure relief valve further comprises:
a first seal member disposed to form a first seal between the first valve member and the cover when the valve is in the closed position; and a second seal member coupled to the second valve member and disposed to engage the first valve member to form a second seal when the valve is in the closed position.

6 . The system of 5 , wherein the second seal being disengaged from the first valve member when the media container is not installed.

7 . The system of claim 5 , further comprising a lever operably coupled to the cover and movable between a first and second position, the lever being configured to engage the first valve member when in the second position.

8 . The system of claim 7 , wherein the first seal opens in response to the lever moving to the second position to open a first fluid path from the tank to an environment.

9 . The system of claim 5 , wherein:
the first valve member and the cover define a first fluid path therebetween; and the first valve member and the second valve member define a second fluid path therebetween.

10 . The system of claim 8 , wherein:
the first seal closes the first gap; and the second seal closes the second gap.

11 . The system of claim 3 , wherein the valve is further movable to a venting position.

12 . A fluid purification device comprising:
a first member, the first member having a first open end; a first element coupled to and disposed about the first open end; and a porous second member, the second member being operably coupled to the first element and enclosing the first open end.

13 . The device of claim 12 , wherein the first ring element is integral with the first member.

14 . The device of claim 12 , wherein the first member is made from a flexible material.

15 . The device of claim 14 , wherein the first member is made from an elastic and flexible material.

16 . The device of claim 12 , wherein the first member is made from a substantially rigid material.

17 . A fluid purification device for use in a fluid purification system having a tank, a valve, and a lever arranged to engage the valve, the valve having an open position and a closed position, the device comprising:
a first member configured to be disposed within the tank, having a purification media disposed therein; and an activation element sized to fit within the tank, the activation element being configured to engage the valve when the activation element is disposed in the tank.

18 . The fluid purification device of claim 17 , wherein the activation element is operably coupled to the first member.

19 . The fluid purification device of claim 17 , further comprising a porous second member, the second member being operably coupled to the activation element and enclosing the end of the first member.

20 . The fluid purification device of claim 17 , wherein the activation element is integral with the first member.

21 . The fluid purification device of claim 17 , wherein:
the tank has a hollow interior extending from an open end, the hollow interior having a predetermined depth; and the activation element includes activation surface, the activation surface being configured to be located 0-30% of the predetermined depth from the open end when the first member is inserted in the tank.

22 . The fluid purification device of claim 17 , wherein:
the tank includes a location surface; and the activation element includes an activation surface that is configured to be parallel with the location surface when the first member is inserted in the tank.

23 . The fluid purification device of claim 22 , wherein the activation element includes an activation surface configured to engage the valve when the first member is inserted in the tank, the activation surface being positioned at least partially within an annular region, the annular region being between 65% to 85% of the tank diameter when the first member is inserted in the tank.

24 . The fluid purification device of claim 17 , wherein the activation element includes a rib extending from a side opposite the valve.

25 . The fluid purification device of claim 24 , wherein the rib contacts the first member.

26 . The fluid purification device of claim 17 , wherein the first member and activation element are sized to fit within a tube that is 220 mm long and has a 205 mm inner diameter, the activation element having an activation surface that is positioned 0 mm to 40 mm from an end of the tube when the first member and activation element are positioned within the cylinder.
