Abstract: A water filter is provided. The water filter includes a filtration material and a filter housing spaced for accommodating at least a portion of the filtration material therein. The water filter also includes a housing cap coupled to an upper end of the filter housing for enclosing the filtration material within the water filter. The housing cap includes an upper portion, a lower portion, and a channel formed through the upper portion and the lower portion. The water filter also includes an interface adapter accommodated in the channel, wherein the interface adapter includes a side wall vertically extending from an upper surface of the interface adapter and partially around a perimeter of the upper surface, and a projection vertically extending from the upper surface, wherein the projection is integrally formed with the upper surface and a portion of the side wall.

Abstract: A filter assembly includes an end cover configured to connect with the water dispenser, and a filter housing assembled with the end cover and comprising a cavity configured to receive a filtering material. The end cover includes a body portion and a mounting portion protruding from the body portion. The mounting portion is configured to releasably attach to the water dispenser and has an oval or oval-like cross-section in a horizontal plane, and both ends of the oval or oval-like cross-section are inwardly recessed. Also described is filter assembly including at least one seal having an oval or oval-like cross-section in a horizontal plane, wherein both ends of the oval or oval-like cross-section are inwardly recessed, and wherein the at least one seal is configured to create a water-tight seal between the mounting portion and the water dispenser. A water dispenser for use with the filter assemblies is also described.

Abstract: A pet water dispenser having a water tank assembly, a filter assembly, and a water pumping assembly. The water tank assembly include a tank body defining an interior space for water storage and a top cover detachably arranged on the tank body above the interior space. The top cover having an upper surface defining a drinking tray with a first water return port. The filter assembly is detachably installed in the interior space and located below the first water return port. The water pumping assembly is detachably connected on a side of the tank body and configured to circulate water from the interior space into the drinking tray where the water returns back to the interior space through the water return port and filter assembly.

Abstract: A filter structure comprises a filtering member, a housing, and an upper supporter. The housing comprises a housing body comprising an opening portion and a housing cap coupled to the opening portion of the housing body. The upper supporter is coupled to the filtering member and disposed on an inner surface of the housing cap. The upper supporter comprises a supporter extending portion extending from the upper supporter portion, the supporter extending portion comprises a filter inlet flow path, a projection portion formed on an inner surface of the filter inlet flow path, and a filter outlet flow path separated from the first filter inlet flow path in the supporter extending portion.

Abstract: A car washing system comprises a filtering unit, a pure water pipeline, a waste water pipeline, a washing pipeline, an optional first branch line, and a second branch line. The filtering unit comprises an RO filter membrane, a filtering pipeline and a booster pump. One end of the filtering pipeline is connected to the inlet of the RO filter membrane. The booster pump is set in the filtering pipeline. The pure water pipeline is connected between a pure water outlet of the RO filter membrane and one end of the washing pipeline. The joint of the pure water pipeline and the washing pipeline is provided with a high-pressure pump. One end of the waste water pipeline is connected with waste water outlet of the RO filtering membrane, and the other end is a discharge end. The second branch line is connected between the waste water pipeline and the washing pipeline.

Abstract: In a method for cleaning a portable filter assembly including an elongated housing and a mouthpiece assembled with an outlet end port of the housing, the mouthpiece is disassembled from a female threaded portion of the outlet end port. A male threaded end connection of a cleaning fluid source is assembled to the female threaded portion of the outlet end port. A pressurized cleaning fluid is supplied from the cleaning fluid source to the outlet end port and through a filter element disposed in a fluid passage of the housing to expel the cleaning fluid and trapped contaminants from an inlet end port of the housing.

Abstract: The present application discloses a filtration device. The filtration device comprises a housing, a lid and a filtration material. The housing comprises at least one outlet hole at a bottom of the housing. The lid is coupled to the housing and comprises at least one inlet hole at a top of the lid. The filtration material is disposed within the housing and comprises a top layer, a particulate treatment layer, an activated carbon fiber layer and a bottom layer. The particulate treatment layer is coupled to the top layer. The activated carbon fiber layer is coupled to the particulate treatment layer. The bottom layer is coupled between the activated carbon fiber layer and the bottom of the housing. A filtration assembly is also disclosed in the present application.

Abstract: A water pitcher with sensing capabilities is provided. The water pitcher includes at least a container adapted or otherwise shaped for retaining water therein, and a cover adapted to cover at least a portion of the container. The water pitcher further includes an indication assembly attached to the container and/or the cover. The indication assembly includes at least a sensor for detecting movement of contents within the water pitcher and/or movement of the pitcher upon expiration of a filter within the pitcher. Upon detecting movement of the pitcher, the sensor is configured to activate an indicator (e.g., an LED) for notifying a user of the expired filter and/or movement of the pitcher during the expiration period of the filter.
