A liquid filtering device that works in conjunction with an existing filtration system to provide, for example, cleaner water in a swimming pool.

A water filter assembly for a refrigeration appliance contains an inlet connection, a filter head, on which a water filter can be mounted, a non-return valve and an outlet connection. The non-return valve is connected to the water filter by way of a hose. The hose can be attached to a connection of the filter head which is already available to feed or drain water, without adjustments to the filter head being required for this purpose.

The invention relates to a device for metering an additive into a fluid, containing a valve body, a fluid inlet, and a fluid outlet. A first channel system extends between the fluid inlet and the fluid outlet in the valve body, and a second channel system extends between the fluid inlet and the fluid outlet in the valve body such that in the operating state fluid can flow from the fluid inlet to the fluid outlet either through the first channel system or through the second channel system. The valve body contains a docking element which is configured for docking a cartridge for the additive. A switchover device is provided which can be switched if the cartridge is docked such that the second channel system is fluidically connected to the cartridge when the cartridge is connected to the docking element.

The present invention relates to a device (1) for liquid treatment, comprising an outer tubular body (10, 20, 30) with an extension along a longitudinal axis a; an inlet conduit (10) for a water flow; an outlet conduit (20) of the water flow in fluid communication with said inlet conduit (10); a central body (45) contained in a central zone inside said outer tubular body (10, 20, 30) and in contact with said water flow, the central body (45) comprising a plurality of discs (40, 41, 42, 43, 44) aligned longitudinally along the direction of the water flow, each of which has one or more holes (40a, 40b, 40c, 40d, 40e, 40f) arranged in a circular crown, each central disc (40, 41, 42, 43, 44) being rotated by a predetermined angle with respect to the preceding central disc (40, 41, 42, 43, 44).

A water purifier includes a water purification unit, and an ice making unit. The water purification unit includes: a water filter for filtering introduced raw water to provide the purified water and unfiltered living water; a purified water tank including a first storage for storing unfiltered water, a second storage for storing the purified water discharged from the water filter, and a separation membrane formed of an impermeable material which independently partitions the first storage and the second storage and has elasticity, wherein the second storage shrinks when the first storage expands, and the first storage shrinks when the second storage expands; a flow channel connecting the water filter, the purified water tank, and the ice making unit to provide a passage through which the raw water, the living water, and the purified water flow; and a valve unit including a plurality of valve modules.

Filtering assemblies to be used with a flowable material container. The assembly includes a filtering screen. The assembly further includes filtering media. The filtering media includes activated carbon. The filtering media includes dissolvable material. The assembly further includes a filtering basket to contain the filtering media. The assembly further includes a valve assembly. The assembly further includes a spout with a filter. The spout further includes a removable filter. The removable filter is configured to extend beyond the end of the spout. The removable filter includes circulation holes. The removable filter is configured to be pushed into the spout by a closure cap. The removable filter is configured to contain filtering media.

A lifting mechanism for a wastewater plant skimmer arm is provided. The device includes a member. A pair of attaching members are each connected to the member via a hinge. The pair of attaching members are parallel from each other. A skimming member is connected to the pair of attaching members, and parallel to the member. A clamp with a pin is mounted to the member. A flat bar is connected to the clamp and pivots about the pin. The flat bar includes a hook and a plurality of notches. A U-bolt placed on the skimming member includes a rod, that may engage with the hook or a notch of the plurality of notches on the flat bar. The hook may lift the skimming member by engaging with the rod. The desired position of the skimming member may be secured by engaging with a notch of the plurality of notches.

A channel for fluid flow comprising a first unit and a second unit connected to each other. The first unit comprises a first u-section having a first open top side, and a first grate extending across the first open top side and removably attached to the first u-section. The second unit comprises a second u-section having a second open top side, and a second grate extending across the second open top side and removably attached to the second u-section. The first grate defines a negative semicircular distal end having a first diameter and a first center point. The second grate defines a positive semicircular proximal end having a second diameter and a second center point. The first center point is coincident with the second center point and the first diameter and the second diameter are sized such that the positive semicircular proximal end fits within the negative semicircular distal end.

A water purifier structure includes a container assembly and a buffer unit mounted in the container assembly. The container assembly includes a housing and a cap unit. The housing has a first receiving section and a second receiving section. The second receiving section of the housing is provided with a retaining portion. The buffer unit is mounted in the second receiving section of the housing and includes a positioning ring secured in the retaining portion of the housing, and a cushioning member mounted in the positioning ring. The cushioning member is elastically movable in the positioning ring. When the cushioning member is compressed by a force, the cushioning member is contracted and elastically deformed toward the second receiving section of the housing, to form a buffering force.
