Abstract: A device for the treatment of water, in particular a filter device. The device has a cartridge which has a container for receiving treatment means for water, particularly for receiving filter means, and a connection head arranged on the container. In addition, a connection element is provided which has a recess for the connection head. At least one locking shaft is provided with which the connection head can be fixed in the connection element. The locking shaft is rotatably mounted and can be rotated from a locking position to an unlocking position and back again.

Abstract: The invention relates to a filter cartridge (1), especially a suction filter cartridge, which is provided, in the outlet opening (20), with an inward-pointing, peripheral snap-on rim (22) which can be folded from a first lower snap position into a second upper snap position and vice versa. The invention also relates to a seat element (30) for such a filter cartridge, comprising a connection sleeve (33) which engages with the outlet opening (20) of the filter cartridge (1). Said connecting sleeve (33) comprises at least one actuator which displaces, when the filter cartridge (1) is placed on the rim, the snap-on rim from a first lower snap position to the second upper snap-on rim from a first lower snap position to the second upper snap positioning which the snap-on rim rests against the connecting sleeve (33) in a sealing and clamping manner.

The device further includes a connecting element, which has a holder for the connecting head with at least one inflow opening and an outflow opening, which are connected to the inlet and outlet openings of the connecting head in a sealing manner by means of sealing elements. The connecting head is tapered toward the free end, wherein the outer surface has at least one first curved outer surface section, which is inclined toward the longitudinal axis of the cartridge, and a second outer surface section opposite from the first outer surface section. The inlet and outlet openings are located in the first and/or the second outer surface sections.

Abstract: The invention describes an apparatus for the filtration of liquids and an associated filter cartridge 100, the correct seating of which is ensured and can be established by the user.

Abstract: A filtration device for liquids is provided and includes a filtration beaker filled with a filtration material and a lid. The lid is connected to the filtration beaker in a liquid-tight manner to define an inner volume, and includes at least one liquid inlet and at least one air vent. A sieve-like textile fabric is disposed in between the filtration beaker and the lid. In order to guarantee secure operation and ensure a good retaining effect with respect to particles having a size of approximately 200 micrometers at different filtration-material fill heights in the filtration beaker, the sieve-like textile fabric has at least one formed part protruding into the inner volume of the lid, whereby air can be found on both sides of the part of the textile fabric which is located farthest away from the filtration beaker.
