20090127178 | PORTABLE WATER PURIFICATION DEVICE - A portable water purification device includes a base, a fixed sleeve, a tube, a filtering unit, and a movable sleeve. The base includes a channel for providing filtered liquid. The fixed sleeve is fixed on the base and includes a first peripheral wall and a first axial hole. The tube on where the filtering unit is mounted is secured on the base and held in the first axial hole to define a penetrated hole communicating with the channel. The movable sleeve is mounted on an external surface of the fixed sleeve, and slid between a first position away from the base and a second position adjacent to the base. The movable sleeve includes a second peripheral wall and a second axial hole whereby the first axial hole communicates with the second axial hole to define a containing room when the movable sleeve is located on the first position. | 05-21-2009 |
20090114587 | NEGATIVE PRESSURE REVERSE OSMOSIS FILTERING MEMBRANE SYSTEM - A negative pressure reverse osmosis filtering membrane system includes multiple reverse osmosis filtering members, multiple buckle units, multiple sealing members, a first base and a second base. Each of the reverse osmosis filtering members includes a supporting plate, a first membrane, a second membrane, and an aperture. The first membrane and the second membrane sandwiches the supporting plate to define a room. The aperture is defined along an axis and through the supporting plate, the first membrane and the second membrane to communicate with the room. The buckle units are embedded next to each other and alternately stacked with the reverse osmosis filtering members. The sealing members are respectively clamped between the buckle unit and the reverse osmosis filtering member. The first base further includes a pump hole communicating with the aperture and pumping the filtered liquid out of the reverse osmosis filtering membrane system by a negative pressure. | 05-07-2009 |
